TOWEL ASSEMBLY WITH COUPLER

Description

CROSS REFERENCE TO RELATED APPLICATIONS

This claims the benefit of U.S. Provisional Application No. 63/706,472, filed on Oct. 11, 2024, which is incorporated in its entirety.

FIELD OF INVENTION

This disclosure relates generally to golf towels and, more particularly, relates to towels comprising a magnetic strap assembly.

BACKGROUND

Golfers frequently use towels during play to clean and dry golf club and balls. To reduce the risk of losing towels, however, golfers tend to leave them attached to a bag or cart. Additionally, individuals with back pain or limited mobility often avoid using a towel that is not secured to the golf bag, as retrieving it from the ground requires bending, which may cause discomfort or physical strain. While some golfers attach a towel to their golf bag via an accessory ring or clip, they typically do not bring the towel with them when moving away from the bag, as detaching and reattaching the towel is inconvenient and disrupts the flow of play.

To address these challenges, certain conventional golf towels have been designed to incorporate magnetic elements that enable temporary attachment to golf club heads or shafts. This configuration mitigates the likelihood of the towel becoming separated from the golfer's personal equipment and obviates the need for bending to retrieve the towel from the ground. However, embedding magnets directly within the towel fabric diminishes magnetic strength and range, and exposes the magnet to moisture and debris absorbed by the towel. Moreover, such designs are incapable of attaching to non-magnetic surfaces, such as golf bags or golf carts. Some designs incorporate magnets within a strap that is affixed to the towel. These straps, however, are frequently of insufficient length to loop around external objects and therefore necessitate additional attachment mechanisms to interface with non-magnetic surfaces. Moreover, the mechanical connection between the strap and the towel is often structurally weak, rendering it susceptible to failure under tensile loading and through prolonged wear. Accordingly, while some conventional magnetic towels may improve accessibility, they are less durable and limit the types of structures to which they can attach.

DETAILED DESCRIPTION

Towel assemblies including a towel and a coupler are described herein that enhance portability, accessibility, and durability during use. The coupler includes a strap that is securely coupled, directly or indirectly, to an attachment region of the towel and enables the towel assembly to distribute externally applied tensile loads over an expanded surface area of the towel substrate. This mitigates localized stress concentrations and is more durable under load-bearing conditions. In particular, the strap comprises a strap towel end coupled to the attachment region, a strap free end opposite the attachment region, a first linking region adjacent the strap towel end, a second linking region adjacent the strap free end, and at least a first and second magnet coupled to the first and second linking regions, respectively. The at least first and second magnets are therefore housed within the strap and separate from the towel material, ensuring they are not exposed to moisture or debris absorbed by the towel. The first and second linking regions are separated by a first fold region extending therebetween, which permits the strap to move between a folded state and an open state, described in greater detail below.

Each of the first and second linking regions, coupled to the first and second magnets, can magnetically engage with external ferromagnetic surfaces or with each other. This is done in part to the first fold region. In particular, the first fold region comprises a first fold region material that is sufficiently flexible to permit the first fold region to transition between an open state, in which the first and second linking regions are spaced from one another, and a folded state, in which the first linking region overlies the second linking region. The strap in the folded state thereby magnetically attracts to itself and forms a closed loop suitable for securing the towel assembly to non-magnetic structures, such as a golf bag handle, cart frame, or belt loop. This configuration provides a versatile and reliable attachment mechanism while preserving the structural integrity of the towel during repeated use.

II. Towel Assembly with Towel and Magnetic Strap Assembly

As previously mentioned, the towel assembly combines a towel and a coupler with a magnetic strap to enhance versatility without compromising durability. The coupler is coupled to the towel in a fashion that distributes tensile loads across a wider surface of the towel substrate, thereby reducing critical stress at the point of coupling and preventing strap detachment. Additionally, the flexible, fray-resistant strap ensures long-term reliability. The magnets allow the strap to be quickly and securely attached to various surfaces or fixtures, improving convenience and accessibility during active use. Together, these features yield a durable, adaptable towel assembly that can be deployed and repositioned across many environments. This significantly enhances portability and functionality without sacrificing structural integrity.

Various embodiments of a towel assembly, described in further detail below, include different coupler configurations and other features. The different coupler configurations affect whether the strap is directly or indirectly coupled to the towel. Additionally, the different coupler configurations affect whether the strap is permanently or releasably attached to the towel, and therefore whether or not the strap can be removed prior to washing the towel to avoid compromising the magnetic efficacy of the strap. For example, in some embodiments, the towel assembly comprises a strap directly coupled and permanently stitched to the towel attachment region. In other embodiments, the strap is permanently stitched in place yet indirectly coupled to the towel attachment region. In further embodiments, the strap indirectly and releasably couples to the towel attachment region. Details of towel assemblies that utilize permanent or releasably affixed couplers are described in further detail below.

A towel assembly 100 comprises a towel 110 and a coupler 120, as shown in FIGS. 1 and B. The coupler 120 is directly and permanently coupled to the towel 110 at a designated attachment region 114 via stitching. The coupler 120 improves the versatility (i.e., ability to transition between open and folded states, and couple with both ferromagnetic and non-magnetic objects) of the towel assembly 100 without compromising durability. In some embodiments, the coupler 120 comprises a strap 130 with a first and second magnetic linking region 133, 134 that can magnetically couple with external ferromagnetic surfaces (see FIG. 3). Additionally, the first and second linking regions 133, 134 may interconnect with each other to form a closed loop, facilitating secure coupling to non-magnetic surfaces and fixtures (see FIGS. 7-9). Accordingly, the strap 130 can be attached to a wider range of surfaces. As further illustrated in FIGS. 1 and 2, the coupler 120 comprises a base 160 permanently stitched to the strap 130 and the attachment region 114 of the towel 110. Permanently attaching the coupler 120 to the towel 110 creates a secure mechanical interface capable of withstanding applied tensile loads, thereby enhancing the structural integrity and long-term durability of the towel assembly 100 under repeated use and stress conditions.

The towel 110 defines a towel perimeter 112 having an attachment region 114 located to securely couple the strap 130 and the base 160 to the towel 110. Strategic placement of the attachment region ensures mechanical resilience and contributes to the long-term durability of the towel assembly 100 under operational stress conditions. In some embodiments, the attachment region 114 may be positioned at a corner of the towel perimeter 112, as illustrated in FIGS. 1 and 2. Positioning the attachment region 114 at a corner of the towel perimeter 112 ensures the tensile forces run both parallel and perpendicular to the lengthwise grain of a towel material. In alternative embodiments, the attachment region 114 may be positioned along a side of the towel perimeter 112.

The towel 110 can be made of any material capable of absorbing moisture and cleaning debris off of a golf club head. For example, the towel 110 can be made of any material such as polyester, cotton, cotton-polyester blend, or synthetic microfibers. In an exemplary embodiment, the towel 110 is made of a polyester material, which is durable, moisture-resistant, and quick-drying to effectively clean and dry the golf club head and golf ball. The towel 110 can additionally comprise various patterns, textures, and/or thicknesses to suit different aesthetic preferences and functional needs. Any of the towel embodiments 210, 310, or 410 described below may comprise the towel material referenced herein.

As described above, the strap 130 has distinct first and second magnetic linking regions 133, 134 capable of attaching to both magnetic and non-magnetic surfaces. As shown in FIGS. 3-9, the strap 130 comprises a strap towel end 131 coupled to the attachment region 114 of the towel 110, and a strap free end 132 positioned opposite the strap towel end 131. Additionally, the strap 130 comprises a first linking region 133 adjacent the strap towel end 131, a second linking region 134 adjacent the strap free end 132, and a first fold region 135 disposed therebetween. The first fold region 135 may move between a folded state (as shown in the plan and bottom views of FIGS. 7 and 8 and side elevation view of FIG. 9), in which the first linking region 133 overlies the second linking region 134, and an open state (as shown in the plan and bottom views of FIGS. 3 and 4 and side elevation view of FIG. 5), in which the first linking region 133 is spaced from the second linking region 134. The strap 130 and each of its above-described components may be unitarily formed from a continuous tubular strap material, described in greater detail below, that is sufficiently flexible to allow movement between the folded and open states.

The strap 130 further incorporates regions of strap stitching to delineate the structural boundaries between the first linking region 133, the second linking region 134, and the first fold region 135 therebetween (see FIG. 3). More specifically, each of the first and second linking regions 133, 134 comprise at least one region of strap stitching to define a discrete pocket within the respective linking region. As shown in FIGS. 3 and 4, the strap 130 may comprise first and second regions of strap stitching 142, 143 at opposite ends of the first linking region 133 to define a first pocket 148. A third and fourth region of strap stitching 144, 145 are positioned at opposite ends of the second linking region 134 to define a second pocket 149. Each region of strap stitching is positioned to enable strap flexibility and to size the pockets for supporting magnets, as described below.

Each of the first and second pockets 148, 149 comprise pocket lengths that are sufficient to support magnets, as shown in FIG. 6. In particular, the first pocket 148 comprises a first pocket length 174 measured along the length of the strap 130 between the first region of strap stitching 142 and the second region of strap stitching 143. Additionally, the second pocket 148 comprises a second pocket 175 length measured along the length of the strap 130 between the third region of strap stitching 144 and the fourth region of strap stitching 145. In some embodiments, the first pocket length 174 is different from the second pocket length 175. In some embodiments, the first pocket length 174 and the second pocket length 175 are the same. In some embodiments, the first and second pocket lengths 174, 175 can be 0.50 inch to 2.00 inches. In some embodiments, the first and second pocket lengths 174, 175 can be 0.50 inch to 0.75 inch, 0.75 inch to 1.00 inch, 1.00 inch to 1.25 inches, 1.25 inches to 1.50 inches, 1.50 inches to 1.75 inches, or 1.75 inches to 2.00 inches. Any of the pocket embodiments 248, 249, 348, 349, 350, 448, or 449 described below comprise pocket lengths 274, 275, 374, 375, 376, 474, 475 similar to the first and second magnet lengths 174, 175 described herein.

The first pocket 148 receives at least a first magnet 137 and the second pocket 149 receives at least a second magnet 138, as shown in FIG. 6. This enables the first and second linking regions 133, 134 to magnetically couple with external ferromagnetic surfaces or with each other (the first magnet 137 of the first pocket 148 magnetically couples to the second magnet 138 of the second pocket 149). In particular, the first magnet 137 is positioned within the first pocket 148 such that a first side 137a is adjacent the first region of strap stitching 142 and a second side 137b is adjacent the second region of strap stitching 143. Similarly, the second magnet 138 is positioned within the second pocket 149 such that a first side 138a is adjacent the third region of strap stitching 144 and a second side 138b is adjacent the fourth region of strap stitching 145.

Each of the first magnet 137 and the second magnet 138 are N52 grade neodymium magnets made from an alloy of neodymium, iron, and boron. N52 grade neodymium magnets are the strongest and most durable grade of neodymium magnets and therefore can easily attract and maintain attraction with ferromagnetic objects such as a golf club head or shaft. Specifically, the first magnet 137 and the second magnet 138 can retain magnetic objects comprising a weight. In some embodiments, the weight can be 3 lbs. to 10 lbs. In some embodiments, the weight can be 3 lbs. to 4 lbs., 4 lbs. to 5 lbs., 5 lbs. to 6 lbs., 6 lbs. to 7 lbs., 7 lbs. to 8 lbs., 8 lbs. to 9 lbs., or 9 lbs. to 10 lbs. Any of the magnet embodiments 237, 238, 337, 338, 339, 437, 438 described below may similarly be N52 grade neodymium magnets capable of retaining the weight described herein.

Each of the first and second magnets 137, 138 comprise magnet lengths selected comfortably fit within their respective pockets, as shown in FIG. 6. In particular, the first magnet 137 comprises a first magnet length 177 measured between the first side 137a and the second side 137b. Additionally, the second magnet 138 comprises a second magnet length 178 measured between the first side 138a and the second side 138b. In some embodiments, the first magnet length 177 is different from the second magnet length 178. In some embodiments, the first magnet length 177 and the second magnet length 178 are the same. In some embodiments, the first and second magnet lengths 177, 178 can be 0.50 inch to 1.75 inches. In some embodiments, the first and second magnet lengths 177 can be 0.50 inch to 0.75 inch, 0.75 inch to 1.00 inch, 1.00 inch to 1.25 inches, 1.25 inches to 1.50 inches, or 1.50 inches to 1.75 inches. Any of the magnet embodiments 237, 238, 337, 338, 339, 437, 438 described below comprise magnet lengths 277, 278, 377, 378, 379, 477, 478 similar to the first and second magnet lengths 177, 178 described herein.

The first and second magnets 137, 138, as shown in FIGS. 3 and 6, are strategically positioned to enable the strap 130 to alternate between the folded and open states. As mentioned above, the first and second linking regions 133, 134 are spaced in the open state and therefore, the first and second magnets 137, 138 are decoupled from each other (see FIG. 6). This allows the strap 130 to extend freely. Alternatively, the first linking region 133 overlies the second linking region 134 in the folded state to form a closed loop (see FIG. 9). This configuration allows the first and second magnets 137, 138 to magnetically couple with each other. The magnetic strength of each of the first and second magnets 137, 138 allows the first and second linking regions 133, 134 of the strap 130 to magnetically couple to external ferromagnetic surfaces while in both the folded and open states. Additionally, the magnetic strength of the first and second magnets 137, 138 allows the strap 130 to maintain the folded state, even when subjected to tensile loads. Therefore, the strap 130 of the coupler 120 resists separation and remains securely fastened to non-magnetic surfaces or fixtures in the folded state.

In the open configuration, the first fold region 135 allows the first and second linking regions 133, 134 to remain spatially separated, keeping the first and second magnets 137, 138 decoupled. In contrast, when the strap 130 is in the folded state, the first fold region 135 permits the first and second linking regions 133, 134 to align and come into close proximity with one another. This further allows the first and second magnets 137, 138 to magnetically couple and form the secure connection, as described above. The first fold region 135 comprises a first fold region length 182 measured along the length of the strap 130 (in the open state) from the second region of strap stitching 143 and the third region of strap stitching 144. The first fold region length 182 further enables the first fold region 135 to reliably transition between the folded and open states. In some embodiments the first fold region length 182 can be 0.50 inch to 2.00 inches. In some embodiments, the first fold region length 182 can be 0.50 inch to 0.75 inch, 0.75 inch to 1.00 inch, 1.00 inch to 1.25 inches, 1.25 inches to 1.50 inches, 1.50 inches to 1.75 inches, or 1.75 inches to 2.00 inches. Any of the fold region embodiments 235, 335, 336, 435, 436 described below comprise fold region lengths 282, 382, 383, 482, 483 similar to the first fold region length 182 described herein.

As mentioned above, the strap 130 may be formed from a continuous tubular strap material that is durable, moisture resistant, and flexible. Such characteristics allow the strap 130 to withstand tensile loading conditions, protect the first and second magnets 137, 138 from moisture that may weaken their magnetic properties, and permit easy rotation between the open and folded states. It is additionally preferred that the strap material comprise a low density and minimal resistance to magnetic fields. This prevents the strap material from distorting or absorbing magnetic flux lines, thereby allowing the first and second magnets 137, 138 to maintain stronger contact with external ferromagnetic surfaces or with each other. The strap material may comprise one or more constituent materials that can be any one of nylon tubular webbing, hypalon, and polyester fabric, or any other durable, yet flexible fabric. In an exemplary embodiment, the strap material is nylon tubular webbing. Any of the strap embodiments 230, 330, or 430 described below may comprise the strap material referenced herein.

In addition to the strap 130, the coupler 120 comprises a base 160 that reinforces the connection between the strap 130 and the attachment region 114 of the towel 110. The base 160 is designed to distribute tensile loads applied to the towel 110 across a broad surface area of the towel substrate. This load dissipation helps prevent localized stress and contributes to the overall durability and longevity of the towel assembly 100. As shown in FIGS. 3-9, the base 160 comprises a base towel end 161 coupled to the attachment region 114 of the towel 110, and a base strap end 162 positioned opposite the base strap end 161 and coupled to the strap towel end 131. The base 160 does not comprise a magnetic component.

Additionally, the base 160 comprises base first and second panels 163, 166 comprising first and second panel towel ends 164, 167 and first and second panel strap ends 165, 168, respectively (see FIG. 5). In particular, the first and second panel towel ends 164, 167 are disposed on and permanently stitched to opposite sides of the attachment region 114. Therefore, the first and second panel towel ends 164, 167 sandwich an area of the towel 110. In some embodiments, the area of the towel 110 sandwiched between first and second panel towel ends 164, 167 can be 3.0 inches² to 6.0 inches². In some embodiments, the area of the towel 110 sandwiched between first and second panel towel ends 164, 167 can be 3.0 inches² to 3.5 inches², 3.5 inches² to 4.0 inches², 4.0 inches² to 4.5 inches², 4.5 inches² to 5.0 inches², 5.0 inches² to 5.5 inches², or 5.5 inches² to 6.0 inches².

Furthermore, the first and second panel strap ends 165, 168 are disposed on and permanently stitching to opposite sides of the strap towel end 131. Therefore, the first and second panel strap ends 165, 168 sandwich an area of the strap 130. In some embodiments, the area of the strap 130 sandwiched between the first and second panel strap ends 165, 168 can be 0.5 inch² to 2.0 inches². In some embodiments, the area of the strap 130 sandwiched between the first and second panel strap ends 165, 168 can be 0.50 inch² to 0.75 inch², 0.75 inch² to 1.00 inch², 1.00 inch² to 1.25 inch², 1.25 inch² to 1.50 inch², 1.50 inch² to 1.75 inch², or 1.75 inch² to 2.00 inches².

The base 160 further incorporates regions of base stitching to permanently and durably connect the base first and second panels 163, 166, the strap 130, and the towel 110. In particular, a first region of base stitching 170, as shown in FIG. 3, surrounds the perimeter of the base first and second panels 163, 166 and more specifically, couples the first and second panel towel ends 164, 167 to each other. The first region of base stitching 170 additionally extends through the attachment region 114 of the towel 110 to anchor it securely between the first and second base panels 163, 166. Furthermore, a second region of base stitching 171, as shown in FIG. 3, couples the first and second panel strap ends 165, 168 to each other and extends through the strap towel end 131. This further secures the base first and second panels 163, 166 while also reinforcing the placement of the strap 130 in relation to the towel 110. This arrangement of stitching ensures that all components of the towel assembly 100 (i.e., the base first and second panels 163, 166, the towel 110, and the strap 130) are permanently joined, allowing the towel assembly to resist tensile loads and maintain long-term structural durability.

The base 160 can comprise a shape that dissipates tensile loads applied to the towel 110 over a larger surface area of the towel substrate, thereby strengthening the connection between the coupler 120 and the towel 110. In some embodiments, the base 160 can comprise a trapezoidal shape in which the base towel end 161 comprises a width greater than the width of the base strap end 162. The wider base towel end 161 enhances the structural integrity of the base-towel connection by increasing the surface area over which tensile forces are distributed. By sandwiching a broader section of the towel 110 between the base towel end 161, the applied pulling or tugging forces are spread across a larger region of the towel material, reducing localized stress concentrations. This expanded load-bearing interface helps prevent detachment of the strap 130 and mitigates wear of the towel assembly 100 during repeated used. In other embodiments, the base 160 can comprise a circular, elliptical, triangular, square, hexagonal, or any other polygonal shape suitable for maintaining the durability of the towel assembly 100.

The base 160 can further be made of a material that resists tearing and yet is sufficiently flexible to permit folding. In some embodiments, the base 160 can be made of polymers (e.g. thermoplastic polyurethane (TPU), thermoset polyurethane, thermoplastic elastomer (TPE), polyether block amide (marked by Arkema as PEBAX®), nylon, or leather. In one exemplary embodiment, the base 160 can be comprised of TPE, which resists pulling forces, permits rotation and bending, and is machine washable. Any of the base embodiments 260 or 360 described below may comprise the base material referenced herein.

Another embodiment is directed to a towel assembly 200 comprising a coupler 220 with a strap 230 that permanently and indirectly couples to a towel 210 via a base 260. The towel 210 and a coupler 220 are similar to the towel 110 and coupler 120 described above. However, the coupler 220 further incorporates a base 260 with an opening 269, as shown in FIGS. 10 and 11. Further, the base 260 may be permanently or removably affixed to the attachment region 214 of the towel 210. In this embodiment, the strap towel end 231 permanently couples to the opening 269, rather than being affixed to the attachment region 114 of the towel 110 and positioned between the first and second panel strap ends 165, 168, as previously described. This configuration, described in greater detail below, enhances the mobility and flexibility of the strap 230. Specifically, the configuration allows the strap 230 to rotate freely between the open state (as shown in FIG. 10) and the folded state (as shown in FIG. 11). Unlike the previously described strap 130, the strap towel end 261 is not directly coupled to the attachment region 214 between the base first and second panels 263, 266. Instead, the strap 230 is indirectly coupled by engaging with the opening 269 of the base 260 that is itself directly affixed to the towel 210.

Similar to the base 160, the base 260 reinforces the connection between the strap 230 and the attachment region 214 of the towel 210. The base 260 shares a similar shape and is constructed from comparable materials as the base 160. This design facilitates the dissipation of tensile loads applied to the towel 210 across a broad surface area of the towel substrate. As shown in FIGS. 10 and 11, the base 260 comprises a base towel end 261 coupled to the attachment region 214 of the towel 210, and a base strap end 262 positioned opposite the base towel end 261 and coupled to the strap towel end 231. Additionally, the base 260 comprises base first and second panels 263, 266 comprising first and second panel towel ends 264, 267 and first and second panel strap ends 265, 268, respectively. In particular, the first and second panel towel ends 264, 267 are disposed on opposite sides of the attachment region 214 and therefore sandwich an area of the towel 210. Because the strap 230 engages with the opening 269 of the base, the first and second panel strap ends do not sandwich an area of the strap 230. In some embodiments, the area of the towel 210 sandwiched between first and second panel towel ends 264, 267 can be 3.0 inches² to 6.0 inches². In some embodiments, the area of the towel 210 sandwiched between first and second panel towel ends 264, 267 can be 3.0 inches² to 3.5 inches², 3.5 inches² to 4.0 inches², 4.0 inches² to 4.5 inches², 4.5 inches² to 5.0 inches², 5.0 inches² to 5.5 inches², or 5.5 inches² to 6.0 inches².

The base 260 further defines an opening 269 located adjacent to the base strap end 262 and extending through both the first and second base panels 263, 266. This opening 269 provides an alternative, non-restrictive attachment surface for the strap 230, enabling direct integration with the base 260 and towel 210 of the towel assembly 200. The opening 269 comprises an opening shape that promotes even stress distribution to mitigate stress concentrations that may arise from tensile loads during use. Specifically, the opening 269 comprises an opening shape with rounded contours designed to securely receive the strap 269 while minimizing localized strain at the strap-base interface. In preferred embodiments, and as illustrated in FIGS. 10 and 11, the opening 269 comprises an obround opening shape. In further embodiments, the opening 269 comprises other opening shapes with rounded contours including, but not limited to elliptical, circular, rounded rectangular, or hourglass shapes.

The base 260 incorporates regions of base stitching that permanently and durably connect the base first and second panels 263, 266 and the towel 210, similar to the base 160. Specifically, the base 260 comprises a first region of base stitching 270, similar to the first region of base stitching 170, which couples the first and second panel towel ends 264, 267 to each other (see FIGS. 10 and 11). The first region of base stitching 270 therefore extends through the attachment region 214 of the towel 210 to anchor it securely between the first and second base panels 263, 266. The base 260 further comprises a second region of base stitching 271, which couples the first and second panel strap ends 265, 268 to each other (see FIGS. 10 and 11). This stitching arrangement ensures that the base first and second panels 263, 266 as well as the towel 210 are integrally joined, allowing the towel assembly to resist tensile loads and maintain long-term structural durability.

The strap towel end 231 is inserted through the opening 269 and looped around the base strap end 262, forming a closed loop that anchors the strap 230 to the integrated base 260 and towel 210. This looped configuration enables a secure mechanical interlock while preserving the flexibility and range of motion of the strap 230. The strap 230 additionally includes towel end strap stitching 272 positioned directly adjacent to the base strap end 262 to constrict and stabilize the closed loop. This towel end strap stitching 272 effectively tightens the strap 230 around the base strap end 262 and enhances the structural integrity of the strap-base interface.

As described above, an alternative embodiment comprises a base 260a devoid of regions of base stitching and instead is releasably coupled to the attachment region 214 of the towel 210 (see FIGS. 12-14). Similar to the base 260 described above, the removable base 260a comprises a base towel end 261a coupled to the attachment region 214 of the towel 210, a base strap end 262a positioned opposite the base towel end 261a and coupled to the strap towel end 231, and an opening 269a adjacent the base strap end 261a. Additionally, the base 260a comprises base first and second panels 263a, 266a comprising first and second panel towel ends 264a, 267a and first and second panel strap ends 265a, 268a, respectively. Specifically, the first and second base panels 264a, 267a clamp opposing sides of the attachment region 214, forming a secure mechanical interface without requiring permanent attachment. This clamping mechanism incorporates a torque-resistant feature that resists rotational displacement and separation under tensile loads, thereby maintaining a stable and reliable connection between the base 260a and the towel 210 during use. The torque-resistant clamp ensures that the base remains affixed to the towel even when subjected to dynamic forces, while also allowing for easy removal or repositioning of the base 260a as needed.

Another embodiment is directed to a towel assembly 300 comprising a coupler 320 with a strap 330 that removably and indirectly couples to a towel 310 via a base 360. The towel assembly 300 comprises a towel 310 similar to the towels 110 and 210, and a coupler 320 having a base 360 with an opening 369 that is similar to the base 260 described above. However, the coupler 320 incorporates a strap 330 comprising a first linking region 333 divided into a first sub-region 340, second sub-region 341, and a second fold region 336 therebetween. The strap 330 further comprises a second linking region 334 that, in combination with the first and second sub-regions 340, 341 of the first linking region 333, receives three magnets 137, 138, 139. This allows the strap to releasably engage with the opening 369 (see FIGS. 15-20). In this embodiment, the first linking region 333 is inserted through the opening 369 and the second linking region 334 is opposite the first linking region 333. Each of the first and second linking regions 333, 334 (having three magnets 137, 138, 139) are designed to magnetically couple with external ferromagnetic surfaces. Additionally, the first and second linking regions 333, 334 may interconnect with each other to form one or more closed loops, facilitating secure coupling to the opening 369 and non-magnetic surfaces. As described above, this dual-mode attachment capability enhances the adaptability and utility of the strap 330 across different environments. Further, it enables a releasable connection to the base 360, allowing for flexible deployment and easy removal.

The strap 330 has distinct first and second linking regions 333, 334 to enable versatile attachment to both magnetic and non-magnetic surfaces. Specifically, the first and second linking regions 333, 334 are designed to maintain a secure attachment between the strap 330 and the base opening 369, ensuring reliable engagement under operational loads. Similar to the strap 230, the strap 330 comprises a strap towel end 331, which inserts through the opening 369, and a strap free end 332 positioned opposite the strap towel end 331. Additionally, the strap 330 comprises a first linking region 333 adjacent the strap towel end 331, a second linking region 334 adjacent the strap free end 332, and a first fold region 335 disposed therebetween. The second linking region 334 and first fold region 335 are positioned and sized similarly to the second linking regions 134, 234 and first fold regions 135, 235. However, the first linking region 333 is lengthened to further include a first sub-region 340 bordering the first fold region 335, a second sub-region 341 bordering the strap towel end 331, and a second fold region 336 disposed therebetween. Both the first and second fold regions 335, 336 may move between distinct open and folded states. In the open state, as shown in FIGS. 16 and 17, the first sub-region 340 is spaced from the second sub-region 341. In the folded state, as shown in FIGS. 18-20, the first sub-region 340 overlies the second sub-region 341 and the first sub-region 340 of the first linking region 333 overlies the second linking region 334. The strap 330 and each of its above-described components may be unitarily formed from a continuous tubular strap material, described in greater detail below, that is sufficiently flexible to allow movement between the folded and open states.

Similar to the straps 130 and 230, the strap 330 incorporates regions of strap stitching to delineate the structural boundaries between the first linking region 333, the second linking region 334, and the first fold region 335 therebetween. Furthermore, the first linking region 333 incorporates regions of strap stitching to partition the first sub-region 340, the second sub-region 341, and the second fold region 336 therebetween. Each region of strap stitching defines a discrete pocket within the respective linking region or linking sub-region. As shown in FIG. 15, the strap 330 may comprise first and second regions of strap stitching 342, 343 at opposite ends of the second sub-region 341 to define a first pocket 348, third and fourth regions of strap stitching 344, 345 at opposite ends of the second linking region 334 to define a second pocket 349, and fifth and sixth regions of strap stitching 346, 347 at opposite ends of the first sub-region 340 to define a third pocket 350. Each region of strap stitching is positioned to enable strap flexibility and to size the pockets for supporting magnets, as described below.

Similar to the pockets 148, 149 described above, each of the first, second, and third pockets 348, 349, 350 comprise sufficient pocket lengths for supporting magnets. In particular, the first pocket 348 comprises a first pocket length 374 measured along a length of the strap 330 between the first region of strap stitching 342 and the second region of strap stitching 343. The second pocket 349 comprises a second pocket length 375 measured along a length of the strap 330 between the third region of strap stitching 344 and the second region of strap stitching 345. The third pocket 350 comprises a third pocket length 376 measured along a length of the strap 330 between the fifth region of strap stitching 346 and the sixth region of strap stitching 347. In some embodiments, the first, second, and third pocket lengths 374, 375, 376 are different from each other. In some embodiments, the first, second and third pocket lengths are the same. In some embodiments, the first, second, and third pocket lengths 374, 375, 376 can be 0.50 inch to 2.00 inches. In some embodiments, the first, second, and third pocket lengths 374, 375, 376 can be 0.50 inch to 2.00 inches. In some embodiments, the first and second pocket lengths 374, 375, 376 can be 0.50 inch to 0.75 inch, 0.75 inch to 1.00 inch, 1.00 inch to 1.25 inches, 1.25 inches to 1.50 inches, 1.50 inches to 1.75 inches, or 1.75 inches to 2.00 inches.

The first, second, and third pockets 348, 349, 350 receive at least first, second, and third magnets 337, 338, 339, respectively. Each of the first, second, and third magnets 337, 338, 339 enable the first and second sub-regions 340, 341 of the first linking region 333 as well as the second linking region 334 to engage in magnetic coupling with external ferromagnetic surfaces or with each other. In particular, the first magnet 337 is positioned within the first pocket 348 such that a first side 337a is adjacent to the first region of strap stitching 342 and a second side 337b is adjacent to the second region of strap stitching 343. Similarly, the second magnet 338 is positioned within the second pocket 349 such that a first side 338a is adjacent to the third region of strap stitching 344 and a second side 338b is adjacent the fourth region of strap stitching 345. Furthermore, the third magnet 339 is positioned within the third pocket 350 such that a first side 339a is adjacent the fifth region of strap stitching 346 and a second side 339b is adjacent the sixth region of strap stitching 347.

Similar to the magnets 137, 138 described above, each of the first, second, and third magnets 337, 338, and 339 comprise magnet lengths allowing the first, second, and third magnets 337, 338, 339 to comfortably fit within their respective pockets. In particular, the first magnet 337 comprises a first magnet length 377 measured between the first side 337a and the second side 337b. The second magnet 338 comprises a second magnet length 378 measured between the first side 338a and the second side 338b. Furthermore, the third magnet 339 comprises a first magnet length 379 measured between the first side 339a and the second side 339b. In some embodiments, the first, second, and third magnet lengths 377, 378, 379 are different from each other. In some embodiments, the first, second, and third magnet lengths 377, 378, 379 are the same. In some embodiments, the first and second magnet lengths 377, 378, 379 can be 0.50 inch to 1.75 inches. In some embodiments, the first and second magnet lengths 377, 378, 379 can be 0.50 inch to 0.75 inch, 0.75 inch to 1.00 inch, 1.00 inch to 1.25 inches, 1.25 inches to 1.50 inches, or 1.50 inches to 1.75 inches.

The strategic positioning of the first, second, and third magnets 337, 338, 339 of the first sub-region 340, second sub-region 341, and second linking region 334 enables the strap 330 to alternate between folded and open states. As mentioned above, the first sub-region 340, second sub-region 341, and second linking region 334 are spaced in the open state and therefore, the first, second, and third magnets 337, 338, 339 are decoupled from each other (see FIGS. 16 and 17). This allows the strap 330 to extend freely. Alternatively, the first sub-region 340 overlies the second sub-region 341, and the first sub-region 340 overlies the second linking region 334 in the folded state to form two closed loops (see FIGS. 18-20). This configuration allows the first magnet 337 and the third magnet 339, as well as the second magnet 338 and the third magnet 339 to magnetically couple with each other. As described above, the magnetic strength of each of the first, second, and third magnets 337, 338, 339 allows the first sub-region 340, second sub-region 341, and second linking region 334 of the strap 330 to magnetically couple to external ferromagnetic surfaces while in both the folded and open states. Additionally, the magnetic strength of the first, second, and third magnets 337, 338, 339 allows the strap 330 to maintain the folded state and retain attachment to the base opening 369, even when subjected to tensile loads. Therefore, the strap 330 of the coupler 320 resists separation and remains securely fastened to non-magnetic surfaces or fixtures in the folded state.

The dimensions of the first and second fold regions 335, 336 of the strap 330 further enable reliable transition between the folded and open states. In particular, the first fold region 335 comprises a first fold region length measured along the length of the strap 330 from the sixth region of strap stitching 347. Furthermore, the second fold region 336 comprises a second fold region length measured along the length of the strap 330 from the second region of strap stitching 343 to the fifth region of strap stitching 346. In the open configuration, the first and second fold region lengths allow the first sub-region 340, second sub-region 341, and second linking region 334 to remain spatially separated, keeping the first, second, and third magnets 337, 338, 339 decoupled. In contrast, when the strap 330 is in the folded state, the first and second fold region lengths permit the first sub-region 340, second sub-region 341, and second linking region 334 to align and come into close proximity with one another. This further allows the first, second, and third magnets 337, 338, 339 to magnetically couple and form the secure connection, as described above. In some embodiments, the first fold region length can be the same as the second fold region length. In some embodiments, the first fold region length can be different from the second fold region length. In some embodiments, first and second fold region lengths can be 0.50 inch to 2.00 inches. In some embodiments, the first fold region length can be 0.50 inch to 0.75 inch, 0.75 inch to 1.00 inch, 1.00 inch to 1.25 inches, 1.25 inches to 1.50 inches, 1.50 inches to 1.75 inches, or 1.75 inches to 2.00 inches.

Similar to the bases 160, 260, the base 360 reinforces the connection between the strap 330 and the attachment region 314 of the towel 310. More specifically, the base 360 comprises a comparable shape and material composition to the bases 160, 260, allowing tensile loads applied to the towel to dissipate across a broad surface area of the towel substrate. As illustrated in FIGS. 15-20, the base 360 includes a base towel end 361 coupled to the attachment region 314 of the towel 310, and a base strap end 362 positioned opposite the base towel end 361 and coupled to the strap towel end 331. The base 360 further comprises base first and second panels 363, 366, which include panel towel ends 364, 367 and panel strap ends 365, 368, respectively. The panel towel ends 364, 367 are disposed on opposite sides of the attachment region 314, thereby sandwiching a portion of the towel 310. In various embodiments, the sandwiched area may range from 3.0 in² to 6.0 in², including sub-ranges such as 3.0-3.5 in², 3.5-4.0 in², 4.0-4.5 in², 4.5-5.0 in², 5.0-5.5 in², and 5.5-6.0 in².

To ensure a permanent and durable connection, the base 360 may incorporate stitching regions that couple the panel towel ends 364, 367 (via a first region of base stitching 370) and the panel strap ends 365, 368 (via a second region of base stitching 371), anchoring the towel securely between the panels and maintaining structural integrity under tensile loading. In additional embodiments, the first and second base panels 363, 366 clamp opposing sides of the attachment region 314. As described above, this clamping mechanism incorporates a torque-resistant feature that resists rotational displacement and separation under tensile loads. Therefore, the torque-resistant clamp ensures that the base remains affixed to the towel even when subjected to dynamic forces, while also allowing for easy removal or repositioning of the base 360 as needed.

Similar to the base 260, the base strap end 362 of the base 360 defines an opening 369 extending through both panels 363 and 366, providing a non-restrictive attachment surface for the strap 330. As described above, this opening 369 features rounded contours to promote even stress distribution and reduce localized strain at the strap-base interface. Preferred embodiments utilize an obround shape, while alternative shapes may include elliptical, circular, rounded rectangular, or hourglass profiles.

Another embodiment is directed to a towel assembly 400 comprising a coupler 420 with a strap 430 that removably and indirectly couples to a towel 410 via a grommet 452. A towel assembly 400 comprises a towel 410 similar to the towels 110, 210, 310. However, the towel 410 comprises an attachment region 414 with a grommet 452 defining a through hole 453. Additionally, the strap 430 comprises a first linking region 433 divided into a first sub-region 440, a second sub-region 441, and a second fold region 436 therebetween. The strap 430 further comprises a second linking region 434 that, in combination with the first and second sub-regions 440, 441 of the first linking region 433, receives two magnets 437, 438 and first and second interlocks 455, 456. This allows the strap to releasably engage with the grommet 452 (see FIGS. 21-30). The coupler 420 does not comprise a base. In this embodiment, the first linking region 433 is inserted via the through hole 453 and the second linking region 434 is opposite the first linking region 433. Each of the first and second linking regions 433, 434 (having two magnets 437, 438) are designed to magnetically couple with external ferromagnetic surfaces or with each other to form a closed loop. This facilitates secure coupling with non-magnetic surfaces. Additionally, the first and second interlocks 440, 441 of the first and second sub-regions 433, 434 may interconnect with each other to form another closed loop, facilitating secure coupling to the grommet 452. As described above, this dual-attachment capability enhances the adaptability and utility of the strap 430 across different environments. Further, it enables a releasable connection to the grommet 452, allowing for flexible deployment and easy removal.

The grommet 452, as described above, is positioned at the designated attachment region 414 of the towel 410, where it defines a through hole 453 configured to receive the removable strap 430. The grommet 452 and through hole 453 feature rounded geometries that enable flexibility of the strap 430 during use, while also minimizing the development of high stress concentrations when the towel assembly 400 is subjected to tensile loads. In particular, the rounded geometries of the grommet 452 and through hole 453 preserve the structural integrity of both the towel fabric and the strap interface by distributing mechanical forces more evenly around the perimeter of the through hole 453. Due to the rounded shaping, the grommet 452 and through hole 453 do not comprise any sharp corners or edges that could create high concentrations in the towel assembly 400. This ensures reliable performance under repeated loading conditions. In some embodiments, the grommet 452 comprises a shape similar to the shape of the through hole 453. In alternative embodiments, the grommet 452 comprises a shape different than the shape of the through hole 453. In preferred embodiments, and as illustrated in FIGS. 21-30, the grommet 452 and the through hole 453 comprise an obround shape. In further embodiments, the gromet 452 and the through hole 453 comprise shapes with rounded contours including, but not limited to elliptical, circular, rounded rectangular, or hourglass shapes.

Additionally, the through hole 453 is dimensioned to comfortably accommodate the removable strap 430, ensuring ease of insertion and removal without excessive friction. The through hole 453 comprises a specific through hole diameter 484, measured from a through hole first side 453a to a through hole second side 453b, to provide sufficient clearance around the strap 430 (see FIGS. 21 and 26). As such, the strap 430 is allowed to pivot, slide, or rotate within the through hole 453 as needed to transition between the open and folded states. This through hole diameter 484 sizing not only supports dynamic movement of the strap 430, but also helps maintain the flexibility and adaptability of the towel assembly, especially when subjected to repeated folding or tensile forces. In some embodiments, the through hole diameter 484 is 0.50 inch to 3.00 inches. In some embodiments, the through hole diameter 484 is 0.50 inch to 0.75 inch, 0.75 inch to 1.00 inch, 1.00 inch to 1.25 inches, 1.25 inches to 1.50 inches, 1.50 inches to 1.75 inches, 1.75 inches to 2.00 inches, 2.00 inches to 2.25 inches, 2.25 inches to 2.50 inches, 2.50 inches to 2.75 inches, or 2.75 inches to 3.00 inches.

The strap 430 has distinct first and second linking regions 433, 434 that attach to both magnetic and non-magnetic surfaces. Specifically, the first and second linking region 433, 434 maintain secure attachment of the strap 430 to the grommet 452, ensuring reliable engagement under operational loads. As shown in FIGS. 21 and 26, the strap 430 comprises a strap towel end 431, which inserts through the through hole 453 of the grommet 452, and a strap free end 432 positioned opposite the strap towel end 431. Additionally, the strap 430 comprises a first linking region 433 adjacent the strap towel end 431, a second linking region 434 adjacent the strap free end 432, and a first fold region 435 disposed therebetween. The second linking region and 434 and first fold region 435 are positioned and sized similarly to the second linking regions 134, 234, 334 and first fold regions 135, 235, 335. Similar to the first linking region 333, the first linking region 433 is lengthened to further include a first sub-region 440 bordering the first fold region 435, a second sub-region 441 bordering the strap towel end 431, and a second fold region 436 disposed therebetween. Both the first and second fold regions 435, 436 may move between distinct open and folded states. In the open state, as shown in FIGS. 22, 23, 27, and 28, the first sub-region 440 is spaced from the second sub-region 441. In the folded state, the first sub-region 440 of the first linking region 433 overlies the second linking region 434, as shown in FIGS. 24, 25, 29, and 30. The strap 430 and each of its above-described components may be unitarily formed from a continuous tubular strap material, described in greater detail below, that is sufficiently flexible to allow movement between the folded and open states.

Similar to the straps 130, 230, and 330, the strap 430 incorporates regions of strap stitching to delineate the structural boundaries between the first linking region 433, the second linking region 434, and the first fold region 335 therebetween. Furthermore, the first linking region 433 incorporates regions of strap stitching to partition the first sub-region 440 from the second sub-region 441 and second fold region 436 therebetween. Each region of strap stitching defines a discrete pocket within the respective linking region or linking sub-region. As shown in FIGS. 21 and 26, the strap 430 may comprise first and second regions of strap stitching 442, 443 at opposite ends of the first sub-region 440 to define a first pocket 448, and third and fourth regions of strap stitching 444, 445 at opposite ends of the second linking region 434 to define a second pocket 449. Similar to regions of strap stitching previously described, each region of strap stitching is positioned to enable strap flexibility and to size the pockets for supporting magnets.

Each of the first and second pockets 448, 449 are sized similarly to the first and second pockets 148, 149 described above to support magnets. As such, the first and second pockets 448, 449 receive at least first and second magnets 437, 438, respectively. The first and second magnets 437, 438 enable the first sub-region 440 of the first linking region 433 as well as the second linking region 434 to engage in magnetic coupling with external ferromagnetic surfaces or with each other. As shown in FIGS. 21 and 26, the first magnet 437 is positioned within the first pocket 448 such that a first side 437a is adjacent to the first region of strap stitching 442 and a second side 437b is adjacent to the second region of strap stitching 443. Similarly, the second magnet 438 is positioned within the second pocket 449 such that a first side 438a is adjacent to the third region of strap stitching 444 and a second side 438b is adjacent to the fourth region of strap stitching 445. The magnets 437, 438 are N52 grade neodymium magnets, identical in composition and strength to magnets 137, 138, 337, 338. In particular, the magnets 437, 438 share the same magnet lengths 474, 475 and are capable of retaining an equivalent amount of weight.

The strap 430 comprises complementary first and second interlocks 455, 456 that securely yet releasably connect the strap 430 to the grommet 452. In some embodiments, the first interlock 455 is positioned at the first sub-region 440 adjacent to the first fold region, and the complementary second interlock 456 is positioned at the second sub-region 441 adjacent the towel end 431 of the strap 430. For example, the first interlock 455 may be coupled to the first magnet 437 of the first sub-region 440, as shown in FIGS. 21-25. In additional embodiments, however, the first interlock 455 may be spaced from the first magnet 437 of the first sub-region 440, as shown in FIGS. 26-30. In some configurations, the interlocks 455, 456 form a complementary snap and button attachment mechanism. In other embodiments, the interlocks 455, 456 may comprise cam locks, bayonet mounts, latch mechanisms, or any other suitable mechanical locking features capable of ensure a strong, yet detachable engagement with the grommet 452.

The first and second magnets 437, 438 as well as the first and second interlocks 455, 456 enables strategic positioning of the strap 430 for alternating between folded and open states. As mentioned above, the first sub-region 440, second sub-region 441, and second linking region 434 are spaced in the open state, as shown in FIGS. 22, 23, 27, and 28. Therefore, the first and second magnets 437, 438 as well as the first and second interlocks 455, 456 are decoupled from each other. This allows the strap 430 to extend freely. Alternatively, the first sub-region 440 overlies the second sub-region 441, and the first sub-region 440 overlies the second linking region 434 in the folded state to form two closed loops (see FIGS. 24, 25, 29, and 30). This configuration allows the first magnet 437 and the second magnet 438 to magnetically couple with each other, and the first interlock 455 to releasably engage with the second interlock 456. The magnetic strength of each of the first and second magnets 437, 438 allows the first sub-region 440 and second linking region 434 to magnetically couple to external ferromagnetic surfaces while in both the folded and open states. Additionally, the magnetic strength of the first and second magnets 437, 438 as well as the mechanical strength of the first and second interlocks 455, 456 allows the strap 430 to maintain the folded state and retain attachment to the grommet 452, even when the strap 430 is subjected to tensile loads. Therefore, the strap 430 of the coupler 420 resists separation and remains securely fastened to non-magnetic surfaces or fixtures in the folded state.

The dimensions of the first and second fold regions 435, 436 of the strap 430 further enable reliable transition between the folded and open states. In particular, the first fold region 435 comprises a first fold region length 482 measured along the length of the strap 430 from the second region of strap stitching 443 to the third region of strap stitching 444. Furthermore, the second fold region 436 comprises a second fold region length 483 measured along the length of the strap 430 from a point 456a of the second interlock 456 positioned furthest from the towel end 431 to the first region of strap stitching 442. In the open configuration, the first and second fold region lengths 482, 483 allow the first sub-region 440, second sub-region 441, and second linking region 434 to remain spatially separated, keeping the first and second magnets 437, 438 as well as the first and second interlocks 455, 456 decoupled. In contrast, the first and second fold region lengths 482, 483 in the folded state permit the first sub-region 440, second sub-region 441, and second linking region 434 to align and come into close proximity with one another. This further allows the first and second magnets 437, 438 to magnetically couple as well as the first and second interlocks to mechanically engage and form a secure connection, as described above. In some embodiments, the first fold region length 482 can be the same as the second fold region length 483. In some embodiments, the first fold region length 482 can be different from the second fold region length 483. The first and second fold region lengths 482, 483 can be similar to the first and second fold region lengths of the first and second fold regions 135, 136, 235, 236, 335, and 336. In particular, the first and second fold region lengths 482, 483 can be 0.50 inch to 2.00 inches. In some embodiments, the first and second fold region lengths 482, 483 can be 0.50 inch to 0.75 inch, 0.75 inch to 1.00 inch, 1.00 inch to 1.25 inches, 1.25 inches to 1.50 inches, 1.50 inches to 1.75 inches, or 1.75 inches to 2.00 inches.

Examples

I. Example 1—Magnetic Load Performance of Towel Assembly with Coupler

The magnetic load performance characteristics of towel assemblies with various magnetic components were tested via a handheld luggage scale. All the towel assemblies comprised towels of comparable dimensions and materials. Additionally, each towel assembly embodiment included a magnetic component designed to facilitate attachment to a ferromagnetic surface, such as a golf club head. Each towel assembly embodiment, however, featured distinct coupler configuration and materials used to house the magnetic components. The magnetic components of the towel assembly embodiments were magnetically coupled to a face center position of a ferromagnetic golf club head. The luggage scale was hooked to the towel assemblies and gradually pulled away from the towel assemblies in identical directions. The luggage scale translated this pulling force into a measurable weight reading. The procedure was video recorded to accurately capture the moment the towel assemblies decoupled from the ferromagnetic golf club head and the peak weight force reading at this moment of decoupling. The peak weight force reading on the scale at the point of separation was identified for each towel assembly by reviewing the video footage. These peak weight force values represented the magnetic holding strength of the respective magnetic couplers, enabling a direct performance comparison between the towel assembly embodiments. The following towel assembly designs were studied: (1) a first control towel assembly comprising a magnetic component encased within a rubber housing that was removably affixed to the towel substrate; (2) a second control towel assembly comprising a magnetic component embedded within a silicone patch that mechanically affixed to the towel substrate; and (3) an exemplary towel assembly comprising a coupler 320 having a magnetic nylon strap 330 removably affixed to a TPE base 360, as described above. At the start of the test, towel assembly (1) was coupled to the face center position with the rubber housing magnetic component. Towel assembly (2) was coupled to the face center position with the silicone patch magnetic component. Towel assembly (3) was positioned in the folded state and coupled to the face center position with the first magnet 337 of the second sub-region 341. Table 1 below displays the peak weight force values required to magnetically decouple the ferromagnetic golf club head from towel assemblies (1), (2), and (3).

As illustrated by Table 1, towel assembly (2) exhibited the worst magnetic load performance and towel assembly (3) retained the greatest amount of weight, significantly outperforming both control towel assemblies. In particular, towel assembly (2) retained the least amount of weight before magnetically decoupling and towel assembly (1) in comparison to towel assemblies (1) and (3). Towel assembly (1) performed only slightly better with a peak weight force increase of 1.16 lb. over towel assembly (2). On the other hand, towel assembly (3) exhibited substantial magnetic load performance improvements with a peak weight force increase of 3.4 lb. over towel assembly (2) and 2.24 lb. over towel assembly (1).

The combination of the nylon strap material and base 360 reinforcement provides a magnetic towel assembly with superior magnetic load performance, as proven by the results. The magnetic load performance of the first and second control towel assemblies was weakened by the use of dense magnet housing materials. The rubber in towel assembly (1) and silicone in towel assembly (2) impeded magnetic field transmission, thereby limiting the peak weight force each assembly was capable of retaining. Furthermore, the absence of a reinforcing base in the first and second control designs proved to result in weaker mechanical performance under tensile loads. In contrast, the nylon material allowed magnetic field to pass through the strap 330 with minimal resistance, preserving the coupling strength of the magnet with the ferromagnetic golf club head. Additionally, the base 360 effectively distributed tensile loads across a wider area of the towel substrate, reducing stress concentrations and enhancing the overall structural integrity of the exemplary towel assembly.

II. Example 2—Manual Detachment Performance of Towel Assembly with Coupler

The manual detachment performance of an exemplary towel assembly comprising the coupler 320 with a removable magnetic strap 330 and base 360 (as described above) was evaluated in comparison to that of a control towel assembly featuring a removably magnetic patch. Both the exemplary and control towel assemblies featured similar sized towels made of comparable materials and included magnetic components designed to couple with ferromagnetic surfaces, such as golf club heads. The two towel assemblies differed, however, in their coupling configurations. The exemplary towel assembly included a removable magnetic strap 330 that was inserted through the opening 369 of the base 360, which was directly affixed to the towel. The strap magnetically coupled to itself, forming a closed loop that secured the connection between the strap 330 and the base 360. In contrast, the control towel assembly featured a silicone patch with an embedded magnet, which mechanically coupled to the towel using a snap and complementary button attachment mechanism.

The manual detachment performance was determined via a time-based removal test. Each trial began with the strap 330 and silicone patch fully attached to their respective towel assemblies. A stopwatch was used to measure the time it took a person to completely remove the strap 330 and silicone patch from the towel. The removal process was repeated three times for each towel assembly, and the individual times were recorded to calculate an average removal time. The average removal time results are displayed in Table 2 below.

As displayed in Table 2 above, the exemplary towel assembly exhibited a decrease in average removal time of 1.9 seconds. This performance advantage can be attributed to the ease of magnetic decoupling compared to the mechanical snap-button disengagement associated with the control towel assembly. Furthermore, the base 360 of the exemplary towel assembly provided a firmer, less flexible surface that facilitated faster and more stable removal of the magnetic strap 330. The exemplary design avoided coupling directly to the unreinforced towel material. In contrast, the control towel assembly relied on the silicone patch that mechanically snapped into a button affixed to the towel substrate. Mechanical attachments on non-reinforced substrates, such as the snap-button configuration of the control assembly, tend to resist quick detachment due to material flexing and misalignment during removal. This not only slows the detachment process, but may also contribute to long-term wear of the towel fabric around the attachment point. Alternatively, the rigid base 360 of the exemplary assembly stabilized the attachment interface, allowing the magnetic strap 330 to be disengaged with minimal resistance. This additionally reduced stress on the towel material and enhanced overall durability of the exemplary towel assembly.
