DETAILED DESCRIPTION

[0026] While the invention may be embodied in various forms, there are shown in the drawings, and will hereinafter be described, some exemplary and non-limiting embodiments, with the understanding that the present disclosure is to be considered an exemplification of the invention and is not intended to limit the invention to the specific embodiments illustrated.

[0027] Example putters disclosed herein have multiple putting configurations that facilitate players with disabilities to more easily and comfortably putt golf balls on putting greens and/or miniature golf courses. For example, each putter has a lefthand configuration, a righthand configuration, and one or more push configurations. Additionally, each putter is configured to enable a player with disabilities to quickly and easily transition between the different configurations of the putter.

[0028] Each putter of the examples disclosed herein includes a shaft and a putter head. The shaft has a lower end and an upper end and extends between the upper end and the lower end along a longitudinal axis. A grip, which facilitates the player in securely holding the putter, may be located at the upper end of the shaft. The lower end of the shaft is rotatably coupled to the putter head via an articulating connection such that the shaft is able to rotate about a rotational axis relative to the putter head. Further, the putter head defines a plurality of putt surfaces. Each putt surface includes a flat, vertical region to facilitate a golf ball in being putt in a straight line. The plurality of putt surfaces includes a front surface and one or more side surfaces. Each side surface is perpendicular to the front surface. In examples with two side surfaces, the side surfaces are opposite and extend parallel to each other.

[0029] In some examples, the lower end of the shaft is rotatably coupled to the putter head via a hosel, which is a connection piece that provides the articulating connection between the putter head and the shaft. For example, the hosel may include a socket into which the lower end of the shaft is securely received. In examples disclosed herein, the hosel is fixedly coupled to the lower end of the shaft and pivotably coupled to the putter head via an articulating connection. In turn, the hosel enables the shaft to rotate relative to the putter head about the rotational axis.

[0030] The combination of the multiple putt surfaces of the putter head and the rotatability of the shaft relative to the putter head (e.g., via the hosel) enable a player, such as a player with disabilities, to quickly easily transition the putter between the various putting configurations.

[0031] With some example putters, the front surface of the putter head is arranged to contact a golf ball, and the shaft is rotated to extend in a first angle relative to the putter head in the lefthand configuration. In the righthand configuration, the front surface of the putter head is arranged to contact the golf ball, and the shaft is rotated to extend in a second opposing angle relative to the putter head. In each push configuration, a respective side surface of the putter head is arranged to contact the golf ball, and the shaft is rotated to extend in a third angle relative to the putter head.

[0032] With other example putters, a first side surface of the putter head is arranged to contact the golf ball, and the shaft is rotated to extend in a first angle relative to the putter head in the lefthand configuration. In the righthand configuration, a second opposing side surface of the putter head is arranged to contact the golf ball, and the shaft is rotated to extend in a second angle (e.g., similar or identical to the first angle) relative to the putter head. In the push configuration, the front surface of the putter head is arranged to contact the golf ball, and the shaft is rotated to extend in a third angle relative to the putter head.

[0033] Additionally or alternatively, example putters disclosed herein may have other features to provide accessibility to player with disabilities. In some examples, the shaft has an a relatively long length (e.g., 43 inches) to facilitate a player in a wheelchair in easily and comfortably using the putter to putt a golf ball. In some examples, a putter may have a ball grabber located at the upper end of the shaft that enables a player to pick up the golf ball from a putting surface and/or a cup without having to bend over and/or reach downward. Further in some examples, the putter head may include a ball scoop that enables a player to scoop the golf ball upward from a putting surface without having to bend over and/or reach downward.

[0034] Turning to the figures, FIG. 1 illustrates an example putter 100 (also referred to as a golf putter, an accessibility putter, a club, a golf club, and an accessibility club) in accordance with the teachings herein. The putter 100 includes a shaft 110 and a head 130 (also referred to as a putter head).

[0035] The shaft 110 includes an upper end 112 and a lower end 114 and extends along a longitudinal axis between the upper end 112 and the lower end 114. In the illustrated example, a grip 116 is located at the upper end 112 of the shaft 110. The grip 116 may be formed of leather, rubber, a cord material, a multi-compound hybrid material, etc. The grip 116 is configured to facilitate a player 10 (FIGS. 4, 6, and 8) in securely holding the putter 100.

[0036] The putter 100 of FIG. 1 also includes a ball grabber 190 that is coupled to and/or extends from the upper end 112 of the shaft 110. The ball grabber 190 is configured to pick up a golf ball 20 (FIGS. 5, 7, and 9-11) from a putting surface and/or a cup without requiring the player to bend over and/or reach downward. In the illustrated example, the ball grabber 190 includes a plurality of flexible finger that extend from the upper end 112 of the shaft 110. To pick up the golf ball 20 with the ball grabber 190, the player 10 is to rotate the putter 100 upside-down, place the ball grabber 190 above the golf ball 20, and subsequently push the putter 100 downward so that the flexible fingers press against the golf ball 20. The flexible fingers expand outward upon being pressed against the golf ball 20, and the golf ball 20 slides into an opening formed between the flexible fingers. Once the golf ball 20 is positioned between flexible fingers, the flexible fingers return inward to retain the golf ball 20 in place until the player 10 removes the golf ball 20 from ball grabber 190 (e.g., with their hand).

[0037] FIGS. 2-3 further depicts the head 130 of the putter 100. The head 130 includes a head body 135. In the illustrated example, the head body 135 defines a bottom surface 142 and a plurality of putt surfaces 153, 163, 173. The bottom surface 142 extends along a bottom of the head 130 and is configured to rest on the putting surface and/or slide along the putting surface as the player 10 performs a putting stroke. Each putt surface 153, 163, 173 extends transversely upward from the bottom surface 142. The bottom surface 142 has an extent residing along a bottom horizonal plane and an extent of each of the putt surfaces 153, 163, 173 is transverse to the bottom horizontal plane. For example, each putt surface 153, 163, 173 is perpendicular to the bottom surface 142. Further, each putt surface 153, 163, 173 in the illustrated example includes a flat, vertical region to facilitate the golf ball 20 in being putt in a straight line along the putting surface.

[0038] In the illustrated example, the plurality of putt surfaces includes a front surface 153 (also referred to as a front putt surface), a side surface 163 (also referred to as a side putt surface, a first side surface, and a first side putt surface), and another side surface 173 (also referred to as a side putt surface, a second side surface, and a second side putt surface). The front surface 153 is perpendicular to each side surface 163, 173. The side surfaces 163, 173 are opposite and extend parallel to each other.

[0039] As shown in FIGS. 2-3, the head body 135 of the head 130 includes a floor 140 that defines the bottom surface 142. The head body 135 of the head 130 also includes a front wall 150 that defines the front surface 153. That is, the front surface 153 is the outer surface of the front wall 150. The front wall 150 is located at a front end of the head 130 and extends upwardly from and perpendicular to the floor 140.

[0040] The head body 135 of the head 130 also includes side walls 160, 170 that define the side surfaces 163, 173, respectively. That is, the side surface 163 is the outer surface of the side wall 160, and the side surface 173 is the outer surface of the side wall 170. The side wall 160 (also referred to as a first side wall) is located along a first side of the head 130, the side wall 170 (also referred to as a second side wall) is located along a second side of the head 130 opposite the first side. Each side wall 160, 170 extends upwardly from and perpendicular to the floor 140. Further, the side walls 160, 170 are opposite and extend parallel to each other.

[0041] The head 130 also includes a ball scoop 144 that enables the player 10 to scoop the golf ball 20 upward from a putting surface without having to bend over and/or reach downward. In the illustrated example, the ball scoop 144 is defined by the floor 140 along a rear end of the head 130. The ball scoop 144 is formed by a circumferential and concave outer surface of the floor 140 that defines a crescent-shaped opening. The outer surface is angled to extend inwardly from the bottom surface 142 to an upper surface of the floor 140. As shown in FIGS. 10-11, the golf ball 20 is to securely rest on the outer surface when the golf ball 20 is scooped up by the ball scoop 144.

[0042] Returning to FIGS. 2-3, the head body 135 of the head 130 also includes a rear wall 156 that is positioned behind and extends parallel to the front wall 150. The rear wall 156 is spaced apart from the front wall 150 to define an opening 138 in which the lower end 114 of the shaft 110 is at least partially extended when the putter 100 is assembled together.

[0043] As shown in FIG. 3, the rear wall 156 defines a through hole 158 and a back surface of the front wall 150 defines a blind hole 154. The blind hole 154 and the rear wall 156 along a rotational axis about which the shaft 110 is configured to rotate relative to the head 130. In the illustrated example, the rotational axis extends parallel to the bottom surface 142 and side surfaces 163, 173 and perpendicular to the front surface 153.

[0044] In the illustrated example, the head body 135 is integrally and monolithically formed together. For example, the head body 135 is formed of material that is durable and enables the head 130 to putt the golf ball 20 in a consistent manner. The head body 135 may be formed of polylactic acid (PLA), nylon, acrylonitrile butadiene styrene (ABS), stainless steel, thermoplastic polyurethane (TPU), etc. For example, a head body formed of PLA may be produced via 3D printing. A head body formed of nylon and/or ABS may be produced via computer numerical control (CNC) machining. Another head body formed of nylon and/or ABS, along with TPU and/or another rubber, may be produced via injection and/or compression molding. For example, such a head body may be molded with nylon and/or ABS and subsequently coated with TPU and/or another rubber. Further, a head body formed of stainless steel may be produced via a die casting process. In other examples, the floor 140, the front wall 150, the rear wall 156, and/or the side walls 160, 170 may be coupled together, for example, via fastener(s) and/or adhesive(s).

[0045] The putter 100 of the illustrated example also includes a fastener 180 that is configured to pivotably couple the lower end 114 of the shaft 110 to the head 130 to provide an articulating connection between the shaft 110 and the head 130. The fastener 180 is configured to be securely received by the blind hole 154 of the head 130 to pivotably couple the head 130 to the lower end 114 of the shaft 110. The fastener 180 extends along the rotational axis, and the lower end 114 of the shaft 110 rotates about the fastener 180 such that the shaft 110 is able to rotate about the rotational axis relative to the head 130. In the illustrated example, the fastener 180 is to extend through the through hole 158 of the rear wall 156, extend through a through hole of the lower end 114 of the shaft 110, and be received by the blind hole 154 of the front wall 150 to pivotably couple the lower end 114 of the shaft 110 to the head 130 about the rotational axis.

[0046] In the illustrated example, the putter 100 includes an insert 185 that is configured to secure the fastener 180 to the head 130. For example, the insert 185 is configured to be inserted into and securely received in the blind hole 154 of the front wall 150 (e.g., via threading, press fit, and other means). The insert 185 includes a hole that is configured to securely receive the fastener 180. For example, the fastener 180 and the hole of the insert 185 are threaded such that the blind hole 154 threadably receives the fastener 180. In other examples, the fastener 180 may be secured to the head 130 without the insert 185. For example, the fastener 180 and the blind hole 154 may be threaded such that the blind hole 154 threadably receives the fastener 180. In other examples, the fastener 180 may be securely received by the blind hole 154 via press fit and/or other means.

[0047] The shaft 110 and the head 130 are assembled together such that the shaft 110 is configured to rotate together about the rotational axis. The shaft 110 is capable of rotating a first maximum angle in a first direction (e.g., toward the side wall 160) relative to a vertical axis and rotating a second maximum angle in a second direction (e.g., toward the side wall 170) opposite the first direction relative to the vertical axis. In the illustrated example, the first maximum angle equals the second maximum angle such that the hosel 120 and the shaft 110 are able to rotate a predefined maximum angle (e.g., 60 degrees) in either direction relative to the vertical axis.

[0048] In the illustrated example, the putter 100 includes a hosel 120 that provides an articulating connection between the lower end 114 of the shaft 110 and the head 130. FIG. 3 further depicts the hosel 120 and the lower end 114 of the shaft 110. The hosel 120 is fixedly coupled to the lower end 114 of the shaft 110. In some such examples, hosel 120 is fixedly coupled to the shaft 110 via press fit and/or an adhesive. In other such examples, the hosel 120 may be integrally and monolithically formed with the shaft 110.

[0049] In the illustrated example, the hosel 120 is T-shaped and at least partially hollow. The hosel 120 includes a first body 122 (also referred to as a hosel-shaft body) and a second body 124 also referred to as a hosel-fastener body). The first body 122 extends perpendicular to and outwardly from a center portion of the second body 124. In the illustrated example, the first body 122 and the second body 124 are integrally and monolithically formed together. In other examples, first body 122 is coupled to the second body 124 via welding, fastener(s), adhesive, etc. The first body 126 defines a hole in which the lower end 114 of the shaft 110 is securely inserted to fixedly couple the shaft 110 to the hosel 120. The second body 124 defines a through hole 218 that is configured to align with the through hole 158 of the rear wall 156 and the blind hole 154 of the front wall 150 when the hosel 120 is placed in the opening 138 of the head body 135 of the head 130.

[0050] With the hosel 120, the fastener 180 is configured to pivotably couple the hosel 120 and, in turn, the shaft 110 to the head 130. The fastener 180 is configured to extend through the through hole 128 of the hosel 120 and be securely received in the blind hole 154 of the head 130 to couple the hosel 120 to the head 130. The fastener 180 extends along the rotational axis and the hosel 120 rotates about the fastener 180 such that to enable the shaft 110 to rotate about the rotational axis relative to the head 130. The hosel 120 is at least partially housed in the opening 138 when coupled to the head 130 in such a manner.

[0051] Turning to FIGS. 4-9, various putting configurations of the putter 100 with the head 130 are depicted. More specifically, FIGS. 4-5 depict the lefthand configuration of the putter 100, FIGS. 6-7 depict the righthand configuration of the putter 100, and FIGS. 8-9 depict a push configuration of the putter 100.

Further, the shaft 110 is rotated about the rotational axis to extend in a second angle relative to the ground surface, the bottom surface 142 of the head 130, and/or the bottom horizontal plane. The second angle may be any angle between the vertical axis and the second maximum angle of rotation. For example, the shaft 110 may be rotated to extend at an angle anywhere between 30 degrees and 90 degrees relative to the ground surface, the bottom surface 142 of the head 130, and/or the bottom horizontal plane.

[0054] In the push configuration of FIGS. 8-9, the side surface 173 of the head 130 is configured to contact the golf ball 20. In another push configuration, the side surface 163 of the head 130 is configured to contact the golf ball 20. In either push configuration, the player 10 holds the upper end 112 of the shaft 110 and positions the golf ball 20 and the head 130 in front of them. Further, the shaft 110 is rotated about the rotational axis to extend in an angle relative to the ground surface, the bottom surface 142 of the head 130, and/or the bottom horizontal plane. That angle may be any angle between the vertical axis and the first or second maximum angle of rotation. For example, the shaft 110 may be rotated to extend at an angle anywhere between 30 degrees and 90 degrees relative to the ground surface, the bottom surface 142 of the head 130, and/or the bottom horizontal plane.

[0055] Turning to FIGS. 12-14, another example head 230 of the putter 100 of FIG. 1 is depicted. In the illustrated example, the head 230 includes a head body 235 and one or more inserts 252, 262, 272 (also referred to as putter inserts and putter plates). The head body 235 defines a bottom surface 142 that extends along a bottom of the head 230 and is configured to rest on the putting surface and/or slide along the putting surface as the player 10 performs a putting stroke. As disclosed below in further detail, each insert 252, 262, 272 is securely coupled to the head 230 and is configured to define an extent of a respective putt surface 253, 263, 273. Each putt surface 253, 263, 273 extends transversely upward from the bottom surface 142. For example, each putt surface 253, 263, 273 is perpendicular to the bottom surface 142. Further, each putt surface 253, 263, 273 in the illustrated example includes a flat, vertical region to facilitate the golf ball 20 in being putt in a straight line along the putting surface.
