GOLF BALL WITH RING DESIGNS IN POLE AREAS FOR IMPROVED ALIGNMENT OPPORTUNITIES

Description

BACKGROUND

Golfers frequently use alignment aids on a golf ball to assist in aligning the golf ball towards a target. Alignment aids may allow golfers to maintain alignment of a target direction from a variety of perspectives around the golf ball. For example, a golfer may use an alignment aid to aim a golf ball while standing behind the golf ball. This may allow the golfer to align the golf ball in the target direction while viewing the target direction from behind the golf ball. The alignment aid may also provide an alignment direction when the golfer is standing above the golf ball to hit the golf ball, allowing the golfer to maintain alignment with the target direction after moving from behind the golf ball in preparation to hit the golf ball in the target direction.

Many current alignment aids may be formed by printing a line on a golf ball that passes through the center of the golf ball at its highest point. From this position, the line appears to be straight as it wraps around the curves of the surface of the golf ball. Solutions are needed, however, to provide alternative alignment aids that can better assist golfers in aiming golf balls in target directions. Such solutions may provide a first circular marking and a second circular marking on the golf ball, where each circular marking is printed around opposite poles of the golf ball. Such solutions provide, for example, a wider view of the alignment aid while standing behind and above the golf ball. Such solutions may further provide circular markings that appear to have a constant diameter around the center point of the pole of the golf ball to provide a consistent alignment aid around each pole of the golf ball that appear linear when viewed from a standard golf position with a golfer standing over and looking down on a golf ball. To achieve such solutions, the circular markings must be precisely printed on the golf ball to counteract the curvature of the golf ball itself. These solutions may provide improved alignment aids to golf balls.

DETAILED DESCRIPTION

Reference will now be made in detail to exemplary embodiments, discussed with regards to the accompanying drawings. In some instances, the same reference numbers will be used throughout the drawings and the following description to refer to the same or like parts. Unless otherwise defined, technical and/or scientific terms have the meaning commonly understood by one of ordinary skill in the art. The disclosed embodiments are described in sufficient detail to enable those skilled in the art to practice the disclosed embodiments. It is to be understood that other embodiments may be utilized and that changes may be made without departing from the scope of the disclosed embodiments. Thus, the materials, methods, and examples are illustrative only and are not intended to be necessarily limiting.

The pad printing methods and processes disclosed herein address technical challenges in printing markings on a spherical object, such as alignment aids on a golf ball. For example, because of the curvature of the golf ball, the farther a stamped linear marking is from a centerline plane of a golf ball, the more distorted the marking appears when ink is transferred to the golf ball. The distorted pattern, as printed on the golf ball, may be particularly noticeable when viewed from a standard golfing position with a golfer standing over and looking down at a golf ball. Due to these distortions, markings that are intended to appear linear, such as alignment aids, may appear to the observer as arcs or curves. This effect is especially noticeable on markings that are not coincident with the centerline plane. The disclosed embodiments address these challenges in printing a first circular marking and a second circular marking on a golf ball. In example embodiments, the method may include an etching pattern, a printing plate, and a pad used to print circular markings on a golf ball. In an example embodiment, the golf ball may be printed with a first circular marking and a second circular marking, where the first circular marking and the second circular marking are printed on opposite poles of the golf ball. The exemplary embodiments address technical challenges by providing a first circular marking and a second circular marking with constant diameters around opposite poles of the golf ball to provide alignment aids that appear linear when viewed from a standard golfing position with a golfer standing over and looking down at a golf ball.

FIG. 1A shows an exemplary pad printing process 100. At step 105, process 100 may comprise aligning pad 140 above etching pattern 145 on printing plate 150. Pad 140 may be an ink transfer mechanism capable of compressing onto etching pattern 145 to transfer an image of etching pattern 145 to another surface. For example, pad 140 may comprise a smooth, resilient stamp block of silicone rubber. The shape and size of pad 140 may vary based on the size of etching pattern 145. Etching pattern 145 may be a 2-D image comprising a pattern to be printed on a spherical object. For example, etching pattern 145 may comprise depressions, or wells, formed in a surface of printing plate 150. Ink may be filled into the depressions of etching pattern 145 to allow transfer of the pattern engraved in etching pattern 145 to a spherical object. Printing plate 150 may be a surface that holds the image to be printed on the spherical object. For example, printing plate 150 may be a flat block in which depressions are created to form etching pattern 145. Ink used in process 100 may include solvent evaporating inks, oxidation curing inks, reactive (catalyst curing or dual component) inks, baking inks, UV curable inks, sublimation inks, or ceramic and glass inks. The ink may optionally contain additives such as binders, reactive prepolymers, thinners, low-viscosity mono and poly-functional monomers, photoinitiators to stimulate polymerization, stabilizing additives, flow control agents, wetting agents, pigments, extenders, or any combination thereof.

At step 110, process 100 may comprise contacting pad 140 with etching pattern 145 on printing plate 150. Pad 140 may contact etching pattern 145, which may allow ink filling etching pattern 145 to transfer to pad 140. At step 115, process 100 may comprise removing pad 140 from plate 150. Ink from etching pattern 145 may now be transferred to pad 140. The ink surface contacting pad 140 may be tacky and adhesive, while the ink surface facing away from pad 140 may be more fluid. At step 120, process 100 may comprise positioning golf ball 155 beneath pad 140. Golf ball 155 may be aligned beneath pad 140 such that the ink on pad 140 is directly above the portion of the surface of golf ball 155 to be stamped. In some embodiments, positioning golf ball 155 beneath pad 140 may comprise moving pad 140 above a stationary golf ball 155. In other embodiments, positioning golf ball 155 may comprise moving golf ball 155 beneath a stationary pad 140. At step 125, process 100 may comprise moving pad 140 to contact golf ball 155. Moving pad 140 to contact golf ball 155 may allow the ink from etching pattern 145 on pad 140 to transfer to golf ball 155. The ink on pad 140 may adhere to the surface of golf ball 155 as pad 140 contacts golf ball 155. At step 130, process 100 may comprise removing pad 140 from golf ball 155. When pad 140 is removed from golf ball 155, the surface of golf ball 155 may have printed marking 160. Printed marking 160 may correspond to etching pattern 145.

FIG. 1B depicts exemplary clamps for holding golf ball 155 during the pad printing process. Golf ball 155 may be held in place by top clamp 165A and bottom clamp 165B. Top clamp 165A may comprise a rounded bottom section for encompassing a top pole of golf ball 155. Bottom clamp 165B may comprise a rounded top section for encompassing a bottom pole of golf ball 155. The rounded bottom section of top clamp 165A and the rounded top section of bottom clamp 165B may be of a diameter the same as or similar to golf ball 155. The width of top clamp 165A and bottom clamp 165B may be less than the diameter of golf ball 155, such that the sides of golf ball 155 extend past the edges of top clamp 165A and bottom clamp 165B to allow pads 140 to print markings on golf ball 155.

FIG. 1C depicts a side view of exemplary top clamp 165A and bottom clamp 165B during the pad printing process. The pad printing process may include two pads 140 for simultaneously printing first circular marking 205A and second circular marking 205B on golf ball 155. Top clamp 165A and bottom clamp 165B may hold golf ball 155 in place while pads 140 press first circular marking 205A and second circular marking 205B onto golf ball 155 simultaneously.

FIG. 2A depicts an exemplary golf ball 155 having first circular marking 205A and second circular marking 205B.

The Y-direction as shown is a side-to-side lateral direction that may be parallel to a target line for a golfer-observer. The Z-direction is directed into and out of the page of the drawing and represents the direction from which the observer views the ball. Centerline plane 210 passes through a center of the golf ball in the Y-Z plane. As is common practice in golf, a golfer may position the golf ball (for example on a putting green or on a tee) such that centerline plane 210 is parallel to or coincident with a target line in the direction in which the golfer intends to hit the golf ball. First circular marking 205A and second circular marking 205B may assist a golfer with aligning or hitting golf ball 155 in the direction of a target line.

Second centerline marking 225B may include a pad-printed marking that is centered on centerline plane 210. Second centerline marking 225B may comprise shapes associated with logos, side stamps, lettering, words, symbols, dashes, numbers, alignment markings, arrows, patterns, or any other stamp that may be printed on a golf ball. In some embodiments, first centerline marking 225A and second centerline marking 225B may comprise the same marking. In other embodiments, first centerline marking 225A and second centerline marking 225B may comprise different markings. Golf ball 155 may be printed with first centerline marking 225A and second centerline marking 225B, either first centerline marking 225A or second centerline marking 225B, or neither first centerline marking 225A nor second centerline marking 225B.

FIG. 2F depicts an exemplary coordinate system for identifying first circular marking 205A on golf ball 155. FIG. 2F is a view of golf ball 155 in a plan view as viewed in a direction toward first reference position 220A. Golf ball 155 may include centerline plane 210 that entirely passes through a center of golf ball 155 and falls within the X-Y plane at the Z=0 position. For example, centerline plane 210 may bisect golf ball 155 and may include a normal that is collinear with the Z-axis. Golf ball 155 may also include a perpendicular centerline plane 215 that may be perpendicular to centerline plane 210. Perpendicular centerline plane 215 may also bisect golf ball 155 and may include a normal that is collinear with the Y-axis. Golf ball 155 may further include first reference position 220A. First reference position 220A may be at a point of intersection between centerline plane 210 and perpendicular centerline plane 215. For example, as shown in FIG. 2F, first reference position 220A may be at the Y=0, Z=0 position of the coordinate system. First reference position 220A may be located at a first center point of a first pole of golf ball 155 when viewed in a plan view as viewed in a direction toward first reference position 220A of golf ball 155.

Adjusted variables may be delivered to production system 310. Production system 310 may be configured to convert the adjusted variables into an adjusted design. The adjusted design may be a representation of the intended design that may compensate for the curvature of golf ball 155. More particularly, the adjusted design may be a design for an etching on a printing plate. The etching may include shapes that produce the intended design when printed on golf ball 155. Production system 310 may be configured to produce a printing plate have an etching. In some embodiments, production system 310 may include an etching system for producing the printing plate. In other embodiments, production system 310 may deliver the adjusted design to a separate machine for etching the printing plate. The printing plate may be delivered to action system 315 for producing a finished golf ball 155. For example, the printing plate may be delivered to a pad printing system for printing a marking on golf ball 155 using the etched printing plate in a manner the same as or similar to the process described herein with respect to FIG. 1. The resulting marking on the finished golf ball may include a marking that matches the intended design as a result of printing using an etching of an adjusted design that compensates for the curvature of golf ball 155.

FIG. 3B is another diagram of the exemplary golf ball printing system 300. Golf ball printing system 300 may include design system 305, production system 310, and action system 315. Design system 305 may include or may be configured to interface with a computing system. The computing system may be configured to modify an intended design to create an adjusted design, as described herein. For example, design system 305 may include central processing unit (CPU) 330, input/output (I/O) unit 325, and plate design unit 335. In some embodiments, design system 305 may include or interface with mark design unit 320. Design system 305 may be configured to receive an intended design and output an adjusted design. For example, plate design unit 335 may be configured to receive an intended design, determine measured variables that depend on the position of the marking on the golf ball, and used the measured variables to determine adjusted variables for an adjusted design. Design system 305 may be configured to send the adjusted variables to production system 310.

Production system 310 may include one or more computing systems and/or plate production device 340 (e.g., a laser etching machine) configured to produce a printing plate 345 having an etching pattern 350. Etching pattern 350 may correspond to the adjusted design. For example, production system 310 may produce the pattern etched printing plate 345 based on the adjusted variables received from design system 305.

Action system 315 may include printer 355 configured to print marking 160 on golf ball 155 by transferring ink from printing plate 345 to golf ball 155. For example, printer 355 may be a pad printing system the same as or similar to FIG. 1. Printer 355 may be configured to transfer ink from printing plate 345 to golf ball 155 to produce marking 160. Marking 160 may correspond to the intended design input to design system 305 when golf ball 155 is viewed from a standard golfing position.

FIG. 4 depicts an exemplary printing plate 150 with etching pattern 145. Printing plate 150 may include plate centerline 410. Plate centerline 410 may correspond to centerline plane 210 of golf ball 155 as described herein with respect to FIG. 2B. Printing plate 150 may also include a plate horizontal centerline 415 that is perpendicular to plate centerline 410.

The disclosed embodiments provide printing methods and golf balls produced by such methods. The disclosed golf balls include markings with an improved appearance by compensating for the curvature of the golf ball during printing. In particular, the design for the etching pattern on a printing plate is adjusted to compensate for a visual distortion that may otherwise occur depending on the position of a marking on the golf ball. The further from the centerline plane of the golf ball, the larger the necessary adjustment of the etching pattern. As a result, a printed appearance of a golf ball in a standard golfing position is visually appealing, more precisely aligns with a target line of the golfer, and eliminates apparent curvature of markings intended to be linear when viewed from the standard golfing position.

While it is apparent that the illustrative embodiments of the invention disclosed herein fulfill the objectives stated above, it is appreciated that numerous modifications and other embodiments may be devised by those skilled in the art. Therefore, it will be understood that the appended claims are intended to cover all such modifications and embodiments, which would come within the spirit and scope of the present invention.
