WALL-MOUNTED EXERCISE SYSTEM

Description

PRIORITY CLAIM

This application claims priority to U.S. Provisional Patent Application No. 63/662,857, filed on Jun. 21, 2024, and titled, “Wall-Mounted Exercise System,” which is incorporated by reference herein.

TECHNICAL FIELD

Numerous embodiments are disclosed for a wall-mounted exercise system that is adjustable in height and can be folded against the wall for efficient storage.

BACKGROUND OF THE INVENTION

The prior art includes wall-mounted ballet bars typically used in dance studios and exercise facilities. Ballet bars are used by dancers, persons during exercise as a stability device to keep their balance while engaging in stretching, dancing, cardiovascular, weight training, and other exercise activities, and persons engaged in physical therapy. These ballet bars typically are mounted to walls, and once installed, cannot be moved vertically. This limits the ability of the bar to adjust to various user heights and types of activities or exercises that can be performed with the ballet bar. For instance, the ballet bar can be difficult to use from a sitting position for users whose height and arm length are not aligned with the fixed height of the ballet bar. The inability of the ballet bar to adjust in height can cause a user to train or engage in physical therapy in improper hip alignment (e.g., the user's hip might tilt due to the placement of the bar), which can further exacerbate an injury or cause an injury to occur. Furthermore, users sometimes will sit or kneel on mats under the ballet bar, but these mats are not attached to anything and will move during strenuous activities or activity that requires movement of the feet while using the ballet bar as a balance or stability support, which increases the risk of injury to the user.

The assignee of this application is an innovator in free-standing ballet bar exercise devices and previously obtained U.S. Pat. Nos. 6,743,152; 7,608,029; 9,295,866; and 10,010,735, each of which is incorporated by reference herein. The inventions of those patents greatly improved upon the prior art, but nevertheless still contained limitations. For instance, free-standing ballet bars are not as stable as wall-mounted ballet bars. The units also can be difficult to move for elderly users and require significant storage space.

What is needed is a wall-mounted ballet bar exercise device that is easily adjustable in height to allow the user to engage with the bar in proper hip alignment and that can be installed as an individual unit or as a set of multiple units. What is further needed is a device that includes a backboard and foldable mat that the user may sit or kneel on when using the ballet bar and that is attached to a fixed structure such as a wall.

Wall-mounted exercise unit 120 comprises bar assembly 101, backboard assembly 102, mounting assembly 103 on the left side and mounting assembly 113 on the right side. Bar assembly 101, backboard assembly 102, and mounting assembly 103 are the same as in FIGS. 1A and 1B. Mounting assembly 113 is the same as mounting assembly 113 in FIG. 1B but is rotated 180 degrees. Bar assembly 101 is attached to mounting assemblies 103 and 113, and mounting assemblies 103 and 113 are attached to wall 104. Mounting assembly 113 is used on the right side of bar assembly 101 when one does not intend to install a second bar assembly to the right of wall-mounted exercise unit 120.

FIG. 1D depicts wall-mounted exercise unit 130. Wall-mounted exercise unit 130 comprises bar assembly 101, backboard assembly 102, and mounting assemblies 113. Bar assembly 101 and backboard assembly 102 are the same as in FIGS. 1A, 1B, and 1C. Mounting assemblies 113 are the same as in FIGS. 1B and 1C, with mounting assembly 113 on the right rotated 180 degrees relative to mounting assembly 113 on the left. Bar assembly 101 is attached to mounting assemblies 113, and mounting assemblies 113 are attached to wall 104. Mounting assemblies 113 are used when one does not intend to install a second bar assembly to either the left or the right of wall-mounted exercise unit 130.

FIG. 2 depicts wall-mounted exercise system 200 that comprises wall-mounted exercise unit 110 mounted to wall 104 on the left-most side of the system, wall-mounted exercise unit 120 mounted to wall 104 on the right-most side of the system, and a plurality of wall-mounted exercise units 100 mounted to wall 104 between wall-mounted exercise units 110 and 120, where adjacent wall-mounted exercise units 100 share a mounting assembly 103. In this example, wall-mounted exercise system 200 comprises three wall-mounted exercise units 100, but it is to be understood that wall-mounted exercise system 200 can comprise any number of wall-mounted exercise units 100, limited only by the size of wall 104. As will be explained in greater detail below, the height of the bar in each wall-mounted exercise unit 100, 110, and 120 can be adjusted to suit the height of the user.

FIG. 3 depicts exercise system 200 mounted to wall 104 as in FIG. 2 but with studs 301 in wall 104 depicted. Studs 301 provide structural integrity for wall 104 and typically are located behind drywall or plaster to form wall 104. Mounting assemblies 103 and 113 each are mounted into one of studs 301. Under modern building practices, studs typically are located 16 inches apart. In this example, mounting assemblies 103 and 113 are located 48 inches apart from adjacent mounting assemblies, meaning they are placed on every third stud 301 within wall 104.

FIG. 4A depicts additional aspects of mounting assembly 103 of wall-mounted exercise units 100, 110, and 120 and wall-mounted exercise system 200. Mounting assembly 103 comprises bracket 401 containing holes 402 and weld nuts 403 on both the left and right sides of bracket 401. Bracket 401 is mounted to studs 301 (not shown) using bolts 404. Holes 402 can receive a stem 817 attached to a pull knob 807 of bar assembly 101 (not shown) as will be described below. Weld nuts 403 receive bolts from bar assembly 101 to fasten bar assembly 101 to bracket 401. In the example shown, bracket 401 comprises four weld nuts 403 and bar assembly 101 is fastened to two of the weld nuts 403, such as the first and third weld nut 403 from the top or the second and fourth weld nut 403 from the top; the former might be used to accommodate a taller user and the latter might be used to accommodate a shorter user. It is to be understood that bracket 401 can contain a larger number of weld nuts 403 to accommodate additional heights or a smaller number of weld nuts 403 to reduce the complexity and cost of the manufacturing of mounting assembly 103. Thus, bracket 401 can accommodate adjacent bar assemblies 101 attached to bracket 401 at different heights.

FIG. 4B depicts additional aspects of the mounting assembly 113 of wall-mounted exercise units 110, 120, and 130 and wall-mounted exercise system 200. Mounting assembly 113 comprises bracket 411 containing holes 402 and weld nuts 403 on the right side of bracket 411. Mounting assembly 113 is similar to mounting assembly 103 except that bracket 411 lacks a set of weld nuts 403 and holes 402 on one side compared to bracket 401, as mounting assembly 113 is intended to be used on an end unit in wall-mounted exercise system 200. Bracket 411 is mounted to studs 301 (not shown) using bolts 404. Holes 402 can receive a stem 817 attached to a pull knob 807 of bar assembly 101 (not shown) as will be described below. Weld nuts 403 receive bolts from bar assembly 101 to fasten bar assembly 101 to bracket 411. In the example shown, bracket 411 comprises four weld nuts 403 and bar assembly 101 is fastened to two of the weld nuts 403, such as the first and third weld nut 403 from the top or the second and fourth weld nut 403 from the top; the former might be used to accommodate a taller user and the latter might be used to accommodate a shorter user. It is to be understood that bracket 411 can contain a larger number of weld nuts 403 to accommodate additional heights or a smaller number of weld nuts 403 to reduce the complexity and cost of the manufacturing of mounting assembly 113. As discussed above with reference to FIGS. 1B, 1C, and 1D, mounting assembly 113 can be rotated 180 degrees and placed on the right side of bar assembly 101.

FIG. 5 depicts additional aspects of backboard assembly 102 of wall-mounted exercise units 100, 110, 120, and 130 (and wall-mounted exercise unit 1100 described with reference to FIG. 11) and wall-mounted exercise system 200. Backboard assembly 102 comprises backboard 501, handle 502, and brackets 503.

FIGS. 6A, 6B, 6C, 6D, 6E, and 6F depict additional aspects of backboard assembly 102 of wall-mounted exercise units 100, 110, 120, 130, and 1100 and wall-mounted exercise system 200 and show how backboard assembly 102 is mounted to wall 104.

In FIG. 6A, a portion of backboard assembly 102 is shown. Backboard assembly 102 comprises mounting strips 601. In this example, mounting strips 601 are sheet metal strips.

FIG. 6B depicts mounting strips 601 mounted to studs 301 from a vantage point within wall 104. Mounting strips 601 are fastened to studs 301 with bolts or another fastening mechanism. Mounting strips 601 also can be fastened at additional points to wall 104 using drywall bolts or another fastening mechanism.

FIG. 6C depicts a backside view of a portion of backboard assembly 102. Backboard assembly 102 comprises four cleats 602 that are shaped to engage with mounting strips 601. Cleats 602 are mounted on backboard 501.

FIG. 6E depicts backboard assembly 102 with optional clamps 603. Clamps 603 can be used to prevent upward movement of backboard assembly 102, as might occur if a tall user has attached bungees 902 (not shown, but shown in FIGS. 9A and 9B) to backboard assembly and pulls upward on the bungees. FIG. 6F depicts backboard assembly 102 with optional clamps 603 screwed into studs 301.

FIGS. 7A, 7B, 7C, 7D, and 7E depict aspects of backboard assembly 102 of wall-mounted exercise units 100 and show how mat 701 is used and how it is attached to backboard 501. The same principles apply to backboard assembly 102 used in wall-mounted exercise units 110, 120, 130, and 1100 as well. In the example shown, mat 701 can be decoupled from backboard 501 so that mat 701 can be replaced when it wears out or if one wants a new mat 701 with a different logo, material, color, or other characteristic.

FIG. 7A depicts backboard assembly 102, which comprises mat 701. In the example shown, mat 701 comprises three segments that can be folded together as shown in FIG. 7B. In FIG. 7B, fastening strip 702 can be used to hold mat 701 in place against backboard 501 by looping around handle 502. Fastening strip 702 can comprise the material known by the trademark “VELCRO” or another fastening material.

FIGS. 7C and 7D depict two alternative implementations of mat 701.

FIG. 7C depicts mat 711, which is one implementation of mat 701. Mat 711 comprises fastening strip 712 (which is an implementation of fastening strip 702) that wraps around handle 502 as shown in FIG. 7B. Mat 711 comprises pocket 713 that can be placed over the top of backboard 501. Pocket 713 includes slot 714 through which handle 502 protrudes when pocket 713 is placed over the top of backboard 501. Mat 711 comprises fastening strip 715 that attaches to another fastening strip (not shown) on the side of backboard 501 that faces mat 711. Fastening strip 715 and the fastening strip on backboard 501 can comprise the material known by the trademark “VELCRO” or another fastening material.

FIG. 7D depicts mat 721, which is another implementation of mat 701. Mat 721 comprises fastening strip 722 (which is an implementation of fastening strip 702) that wraps around handle 502 as shown in FIG. 7B. Mat 721 comprises pocket 723 that can be placed over the top of backboard 501. Pocket 723 includes slot 724 through which handle 602 protrudes when pocket 723 is placed over the top of backboard 501. Mat 721 comprises flaps 725 and 727. Flap 725 comprises fastening strip 726 and flap 727 comprises fastening strip 728. Fastening strips 726 and 728 can comprise the material known by the trademark “VELCRO” or another fastening material. When pocket 723 is placed over the top of backboard 501, flaps 725 and 727 wrap around backboard 501 and fastening strips 726 and 728 secure to one another as shown in FIG. 7E.

FIGS. 8A, 8B, 8C, 8D, 8E, and 8F depict details regarding bar assembly 101 of wall-mounted exercise units 100, 110, 120, and 130 and wall-mounted exercise system 200.

FIG. 8A depicts bar assembly 101, which comprises bar 801, crossbar 802, clamps 803a and 803b, and vertical adjustment mechanisms 804a and 804b. Bar 801 in one embodiment is made of wood with a diameter of 50 mm but it is to be understood that bar 801 can be made of other materials such a metal or plastic and can be of any diameter. Crossbar 802 in one embodiment is made of steel but it is to be understood that crossbar 802 can be made of other materials such as another metal or plastic. Vertical adjustment mechanisms 804a and 804b are mirror-images of each other. Clamps 803a and 803b are mirror images of one another, as clamp 803a is designed to hold the left ends of bar 801 and crossbar 802 and clamp 803b is designed to hold the right ends of bar 801 and crossbar 802.

Vertical adjustment mechanism 804a comprises rail 805, carriage 806a, pull knob 807, and end cap 808. Vertical adjustment mechanism 804b comprises rail 805, carriage 806b, pull knob 807, and end cap 808. Carriages 806a and 806b are mirror images of each other, as carriage 806a is designed to hold clamp 803a and carriage 806b is designed to hold clamp 803b. Carriages 806a and 806 fit within each instance of rail 805 and can move up and down within rail 805 when pull knob 807 is pulled outward. When pull knob 807 is not pulled outward, pull knob 807 and its attached mechanism (described below) holds carriage 806a or 806b in place such that it cannot move up and down within rail 805. Clamps 803a and 803b are attached to carriages 806a and 806b, respectively (or are each formed of the same piece as their respective carriage 806), and move up and down when carriages 806a and 806b move up and down.

FIG. 8B shows a portion of bar assembly 101 from a vantage point below bar 801. Clamp 803a comprises bolt 809 and optional screw 810. Bolt 809 tightens clamp 803a around bar 801 and reduces or eliminates movement of bar 801. Optional screw 810 further secures bar 801 to clamp 803a and reduces or eliminates rotational movement of bar 801 within clamp 803a. Clamp 803b (not shown) contains bolt 809 and, optionally, screw 810 as well and operates in the same manner.

FIG. 8C depicts a portion of bar assembly 101 without bar 801 for convenience. Clamp 803b comprises nut 811 to receive bolt 809 and optional screw hole 812 (which will be present if screw 810 is present) to receive optional screw 810 (not shown). Bolt 809 is driven into nut 811 and nut 815 (not shown, but shown in FIG. 8E) to tighten clamp 803 around bar 801 (not shown). Carriage 806b comprises recess 813 to receive constant force spring 814 (shown in FIG. 8D). Clamp 803a also contains nut 811, recess 813, and, optionally screw hole 812 and operates in the same manner as clamp 803b.

FIG. 8D depicts a portion of bar assembly 101. Bar assembly 101 comprises constant force spring 814 which engages with carriage 806a to provide assistance to the user when moving carriage 806a upward or downward. Specifically, constant force spring 814 provides upward force, which can assist the user to move carriage 806a upward and can counteract the force of gravity when the user moves the carriage 806a downward so that it does not drop too quickly when the user pulls out pull knob 807. Carriage 806b also contains constant force spring 814 and operates in the same manner.

FIG. 8E depicts a cross section of various components in a portion of bar assembly 101, including bar 801, clamp 803a, pull knob assembly 820, rail 805, bolt 810, nuts 811 and 815, and holes 816. Pull knob assembly 820 comprises pull knob 807, stem 817, nut 818, spring 819, and pin 821 (shown in FIG. 8F). Spring 819 is captured between a flange on stem 817 and a pocket in nut 818. When the user wishes to change the height of bar 801, the user pulls pull knob 807 outward in one of carriages 806a and 806b. Spring 819 will exert force on pull knob 807 in the inward direction such that if the user releases pull knob 807, it will move inward.

With reference to both FIGS. 8E and 8F, stem 817 contains pin 821 that sits within grooves 822 in nut 818 (only one groove 822 is shown in FIG. 8F; another groove 822 is not shown and is on the opposite side of nut 818) when stem 817 is in the inward position. The user can pull pull knob 807 outward such that pin 821 exits grooves 822, and the user can then twist pull knob 807 in the clockwise or counterclockwise directions to cause pin 821 to sit against nut 818 outside of grooves 822. This locks pull knob 807 and stem 817 in an outward position such that stem 817 is not in any of the holes 816. After the user pulls and twists one of the pull knobs 807, the user can then pull and twist the other pull knob 807 (or simply pull it and hold onto it). This ensures stems 817 on both sides are not contained in any of the holes 816. The user adjusts bar 801 to the desired height and releases or untwists pull knobs 807. If properly aligned, stems 817 will be inserted into one of the holes 816; if not properly aligned, stems 817 will hit rail 805 and the user will need to move bar 801 slightly upward or downward until stems 817 extend into holes 816 on each side. Once stems 817 are extended into holes 816, bar 801 will be secured in place vertically.

FIG. 9A depicts collar 901. FIG. 9B depicts bungee 902. FIG. 9C depicts exercise unit 100 and wall-mounted exercise system 200 with collar 901 attached to bar 801 in bar assembly 101, and bungee 902 attached to collar 901. A user can exercise using bungee 902, either while standing or sitting on mat 701 in an unfolded position or while standing or sitting on the floor with mat 701 folded up against backboard 501. Bungee 902 (or additional bungees 902) also can attach to handle 502, brackets 503, bar 801, or carabiner 1001 (not shown here but shown in FIGS. 10A, 10B, and 10C). Collar 901 and bungee 902 can be used with exercise units 110, 120, 130, and 1100 in the same manner.

FIGS. 10A, 10B, and 10C depict additional aspects of backboard assembly 102 of wall-mounted exercise units 100, 110, 120, 130, and 1100 and wall-mounted exercise system 200. In FIG. 10A, carabiners 1001 can be attached to brackets 503. With reference to FIG. 10B, a user can attach bungees 902 to one or more of carabiners 1001 or collars 901. In this example, a first bungee 902 is attached to collar 901, which is attached to bar 801, and runs through carabiner 1001 in the bottom left corner of backboard assembly 102, and second bungee 902 is attached to carabiner 1001 in the upper right corner of backboard assembly 102 and runs over bar 801. The user can then exercise with the first bungee 901 and/or the second bungee 902. FIG. 10C depicts another example where a first bungee 902 is attached to carabiner 1001 in the bottom left corner of backboard assembly 102. The user can then exercise with the first bungee 901. It is to be understood that FIGS. 10B and 10C are mere examples and that a user can attach one or more bungees 902 to one or more collars 901 attached to bar 801 and/or to one or more carabiners 1001 in any possible combination.

FIGS. 11-13 depict wall-mounted exercise unit 1100, which is designed to operate as a single unit mounted on wall 104.

FIG. 11 depicts wall-mounted exercise unit 1100. Wall-mounted exercise unit 1100 comprises bar assembly 1101 and backboard assembly 102. Unlike wall-mounted exercise units 100, 110, 120, and 130, wall-mounted exercise unit 1100 does not include mounting assembly 103 or mounting assembly 113. Instead, bar assembly 1101 attaches directly to wall 104. Bar assembly 1101 is identical to bar assembly 101 except as to the differences discussed below with reference to FIGS. 12-14. Backboard assembly 102 is the same as shown in previous Figures, and the previous discission of backboard assembly 102 applies to backboard assembly 102 in wall-mounting exercise unit 1100 as well. For the discussion that follows, it is to be understood that when a component of bar assembly 1101 is identical to a component of bar assembly 101, the previous discussion of the component in bar assembly 101 applies to the component of bar assembly 1101 as well.

FIG. 12 depicts wall-mounted exercise unit 1100, including bar assembly 1101 and backboard assembly 102, from the back side.

Bar assembly 1101 comprises bar 1201, crossbar 1202, clamps 1203a and 1203b, and vertical adjustment mechanisms 1204a and 1204b. Vertical adjustment mechanism 1204a comprises rail 1205, carriage 1206a (not shown), pull knob 1207, and end cap 1208. Vertical adjustment mechanism 1204b comprises rail 1205, carriage 1206b (not shown), pull knob 1207, and end cap 1208. Bar 1201 is identical to bar 801 except that bar 1201 is longer, as described below with reference to FIGS. 14A, 14B, and 14C. Crossbar 1202 is identical to crossbar 802 except that crossbar 1202 is longer, as described below with reference to FIGS. 14A, 14B, and 14C. Clamps 1203a and 1203b are identical to clamps 803a and 803b, respectively. Carriages 1206a and 1206b are identical to carriages 806a and 806b, respectively. Pull knob 1207 and its attached mechanism and end cap 1208 are identical to pull knob 807 and its attached mechanism and end cap 808 discussed previously.

Vertical adjustment mechanisms 1204a and 1204b and their respective rails 1205 are identical to vertical adjustment mechanisms 804a and 804b and their respective rails 805 except that rails 1205 include the additions of spacers 1209. In one embodiment, spacers 1209 comprise metal pieces welded onto rails 1205. Spacers 1209 contain holes through which bolts can be placed to mount bar assembly 1101 to wall 104 (not shown), and spacers 1209 will be the only portion of bar assembly 1101 that will physically touch wall 104. Spacers 1209 guarantee that a gap will be present between the other portion of rails 1205 and wall 104, which will allow the stems of pull knobs 1207 to protrude through holes 1210 without contacting wall 104, which is shown in FIG. 13.

FIG. 13 depicts bar assembly 1101 installed into wall 104. Wall 104 comprises stud 301 and drywall 1301 over stud 301. Spacers 1209 cause a gap 1302 to be present between rail 1205 and drywall 1301, which allows stem 1303 attached to pull knob 1207 to protrude through a hole 1210 in rail 1205 without touching drywall 1301.

FIG. 14A depicts wall-mounted exercise unit 100, FIG. 14B depicts wall-mounted exercise unit 1100, and FIG. 14C depicts wall-mounted exercise unit 130 for a side-by-side-by-side comparison. With reference to FIG. 14A, and as explained previously, wall-mounted exercise unit 100 comprises bar assembly 101, backboard assembly 102, and mounting assemblies 103. Mounting assemblies 103 are mounted into two of the studs 301. Bar assembly 101 comprises bar 801 and crossbar 802. With reference to FIG. 14C, and as explained previously, wall-mounted exercise unit 130 comprises bar assembly 101, backboard assembly 102, and mounting assemblies 113. Mounting assemblies 113 are mounted into two of the studs 301. Bar assembly 101 comprises bar 801 and crossbar 802.

Wall-mounted exercise unit 110 would follow the same principles shown in FIG. 14A for mounting assembly 103 and in FIG. 14C for mounting assembly 113. Wall-mounted exercise unit 120 would follow the same principles shown in FIG. 14A for mounting assembly 103 and in FIG. 14C for mounting assembly 113.

With reference to FIG. 14B, and as explained previously, wall-mounted exercise unit 1100 comprises bar assembly 1101 and backboard assembly 102. Bar assembly 1101 comprises vertical adjustment mechanisms 1204a and 1204b, bar 1201, and crossbar 1202. Vertical adjustment mechanisms 1204a and 1204b are mounted into two of the studs 301. Because wall-mounted exercise unit 1100 does not include mounting assemblies 103 or 113, bar 1201 and crossbar 1202 are longer than bar 801 and crossbar 802 because mounting assemblies 103 are designed to be shared by two wall-mounted exercise units 100, resulting in bar 801 and crossbar 802 spanning a distance slightly inward of two adjacent studs.
