Introduction to the Disclosed Technology

[056] Typically, a person grabs a striking implement, such as a stick or a bat, with the small finger of their non-dominant hand near one end of the implement and their dominant hand adjacent the non-dominant hand towards the other end of the implement. It has been determined that when the person holds the implement straight up, their non-dominant hand and wrist naturally position themselves in a 10-40 degree angle (ulnar neutral position) and a 95-120 degree angle between implement, hand/wrist, and forearm, as shown for example in FIG. 29. Typical implements, however, do not fit the natural shape of the hand. Therefore, gaps exist between the hand and implement, which result in energy loss during a swing, throw, hit, etc.

[057] For maximal comfort and power, a user should hold a striking implement such that their wrist is in straight alignment with their forearm. However, if the user holds the striking implement with a neutral wrist, an obtuse angle of approximately 113° is formed between the forearm and the striking implement due to the natural slant of a person's hand. In order for a user to hold the striking implement in the correct position for striking, the angle between the implement and the forearm should be approximately 90°. This discrepancy forces the user to bend their wrist towards their radius bone (which can be referred to as "radial deviation"). The combination of a deviated wrist and the forces generated by hitting something with an implement can not only cause discomfort, but can also injure the user. In particular, the combination of radial deviation and swinging an implement can fracture the hamate bone in the wrist, located at the base of the fifth metacarpal (also referred to as the "little finger").

[058] Also, when using implements with knobs, such as a baseball bat, users frequently hold the implement at its end for maximum leverage and power. This forces the user to rest the hypothenar region (palm) of their hand against the knob in an effort to achieve the 10-40 degree angle and/or the 95-120 degree angle. Due to the friction between the user's hand and the knob, blistering, bruising, and hamate bone fractures to the hypothenar region of the hand can occur. For example, 10.80% of active Major League Baseball players (as of November 28, 2016) have broken their hamate bone because of the compression between the knob and hypothenar region of the hand. Furthermore, this "knob grabbing" technique causes greater inefficiencies between hand and handle that not only cause energy to be transferred inefficiently from the user to their hit, but also decreases a user's control.

[059] The problems with forcefully swinging a striking implement held with a radially deviated wrist are not limited to baseball bats, and methods or devices to help a user maintain a neutral wrist in other activities are desired. For example, users of diverse striking implements may benefit from a neutral wrist grip.

[060] Described herein are devices and methods which modify striking implements (e.g., lacrosse sticks, field hockey sticks, hockey sticks, hurling sticks, cricket bats, baseball bats, etc.) to increase the user's comfort, lessen the possibility of injury, and/or increase the power capable of being transferred to the ball or other object being struck. The disclosed devices and methods can also be used with other hand-held devices including oars, paddles, fishing rods, canes, handles, etc.

[061] In some embodiments, the devices and methods include ergonomic grips for striking implements that position a striking implement at a 10-40 degree angle relative to the user's hand and/or a 95-120 degree angle relative to the user's forearm, thus helping the user maintain a neutral wrist position. In certain embodiments, the grips can be configured to position the striking implement at a 20-30 degree angle relative to the user's hand and/or a 100-1 15 degree angle relative to the user's forearm. In one particular embodiment, a grip can position the striking implement at a 23 degree angle relative to the user's hand and/or a 109 degree angle relative to the user's forearm, as shown for example in FIG. 30. Accordingly, the disclosed grips can, for example, improve a user's comfort, energy transfer, and control of the implement. The disclosed grips can also reduce the possibility of injury to the user's hand and/or wrist.

[062] In some embodiments, the devices and methods include an ergonomic grip that a user can use with standard striking implements and/or other types of devices. In certain embodiments the devices and methods include an ergonomic grip that can be added to striking implements during manufacture.

[063] In some embodiments the ergonomic grip for a striking implement allows the user to maintain a neutral wrist position while holding the implement at approximately 109° relative to the user's forearm. In particular embodiments, the devices and methods include an angled

ergonometric grip with an apex near the user's little finger when in use.

[064] For simplicity, certain embodiments are described in the context of a particular sport (e.g., baseball, lacrosse, etc.). It should be noted, however, that any embodiment and/or feature of the embodiment may be used for or adapted to other activities. For example, an embodiment of a grip described in connection with a baseball bat can be used for or adapted to other sporting good bats, clubs, and/or sticks, as well as other similarly handled objects such as hammers and barbells.

Exemplary Embodiments

[065] FIG. 4 shows an exemplary baseball bat 200. The baseball bat 200 includes a longitudinal axis 202, a transverse axis 203 having a diameter 209, an outer surface 204, a top terminus 205, a handle portion 206, and a bottom terminus 207. Further, many embodiments comprise a knob 208 located near the bottom terminus 207, as shown in the illustrated embodiment.

[066] FIGS. 1-3 depict an exemplary embodiment of a grip 100. The grip 100 comprises a longitudinal axis 102, a transverse axis 103, a bottom terminus 104, a top terminus 105, a length extending from the bottom terminus to the top terminus parallel to said longitudinal axis, an outer surface 106, and an inner surface 107. The outer surface 106 further comprises a slanted region 108 having an apex 109 near the bottom terminus 104 of the grip 100 and a nadir 110 near the top terminus 105 of the grip 100. As shown in FIG. 5, the inner surface 107 of the grip 100 includes a semi -circular trench with a diameter 210 substantially the same as the diameter 207 of the transverse section of the handle portion 206 of the bat 200 so that at least 80% of inner surface 107 contacts the outer surface 204 of the bat 200 when the grip 100 is placed against the handle 206 of the bat 200.

[067] Referring to FIG. 3, the slanted region 108 further comprises an angle 111 having a vertex at the nadir 110 and comprised of a first ray extending from the nadir 110 of the slanted region 108 to the apex 109 of the slanted region 108 and a second ray parallel to the longitudinal axis 102 of the grip 100. In some embodiments, the angle 111 is between 1-15 degrees or between 3-10 degrees. In particular embodiments, the angle 111 is between 4-8 degrees or between 6-7 degrees. The grip 100 also comprises a length 112 which is approximately equal to the width of a user's hand.

[068] The inner surface 107 can comprise an attachment means 113 for attaching the grip to a striking implement. In some embodiments, the attachment means 113 is an adhesive (e.g., glue and/or or tape covered until use with a removable shield). For example, the attachment means 113 can be used to attach the inner surface 107 of the grip 100 and/or the handle 206 of the bat 200, as shown in FIGS. 4-5. The inner surface 107 of the grip 100 is placed against the handle 206 of the bat 200 such that the bottom terminus 104 of the grip 104 is located at or near the bottom terminus 207 of the bat 200. In certain embodiments, the bottom terminus 104 of the grip 104 can abut the knob 208 of the bat 200. [069] In lieu of or in addition to the attachment means 113, tape (grip tape and/or athletic tape) can be wound around the grip 100 and the handle 206 of the bat 200 to hold secure the grip 100 to the bat 200. Additionally or alternatively, the grip 100 can include one or more holes though which a user could drive a fastener (e.g., a nail or a screw) into the bat to prevent the sleeve and bat separating.

[070] In some embodiments, the grip 100 can be configured such that the frictional engagement between the grip 100 and the handle of the bat prevents the grip from moving relative to the bat during use. In certain embodiments, tape or a wrap can be wrapped around the grip 100 to secure the grip relative to the bat.

[071] A batter using the bat 200 with the grip 100 can slide the fingers of their non-dominant hand towards the top or bottom terminus of the wedge until the position of their fingers is such that the bat is held at between 95° and 120° or between 100° and 115° relative to their non-dominant forearm while their wrist is in its neutral position, in alignment with the forearm. In particular embodiments, the angle formed by the bat and the user's forearm is between 108-110° or 109° (see e.g., FIG. 30). The user's dominant hand is then also placed into the user's preferred location along the handle of the bat.

[072] In certain embodiments, the apex 109 of the grip 100 can extend radially outwardly approximately 0.25-0.75 inches from the outer surface 204 of the bat 200. This configuration, for example, positions most users' wrists in a neutral position when holding the bat 200. In some embodiments, a grip 100 having an angle 111 greater than 9° with a vertex proximal to the bottom terminus 104 of the grip 100 and extending radially outwardly approximately 0.5 inches from the outer surface 204 of the bat 200 can also accommodate most users. In other embodiments, the apex 109 of the grip can extend radially outwardly farther or less than 0.5 inches to achieve the neutral position.

[073] FIGS. 6-7 show an exemplary embodiment of a grip 300. The grip 300 can be configured similar to the grip 100, except the grip 300 extends annularly around the entire handle of striking implement rather than just a portion of the handle like the grip 100.

[074] The grip 300 comprises a longitudinal axis 301, a transverse axis 302, a bottom terminus 303, a top terminus 304, an outer surface 305, and an inner surface 306 defining a lumen having an inner diameter consistent across the lumen. The outer surface 305 of the grip 300 is asymmetrical such that the grip 300 has a cross-sectional profile similar to that of the grip 100 and the bat 200 shown in FIG. 5, other than the grip 300 has a hollow portion for the lumen. The lumen can, for example, allow a user to slide the grip 300 onto the handle of a bat. [075] Referring to FIG. 6, the grip 300 further comprises a first open end 307 and a second open end 308. In some embodiments, the grip 300 can be stretched over the knob of a bat and placed into position on the handle of the bat so that the bottom terminus 303 of the grip 300 is disposed adjacent the bottom terminus of the bat.

[076] In certain embodiments, the grip 300 can include a plurality of perforations or holes 309. The holes 309 can, for example, decrease the amount of force necessary to stretch the sleeve over the knob and onto the handle of the bat. In some embodiments, one or more of the holes 309 extend through the grip 300 (e.g., from the outer surface 305 to the inner surface 306). In other

embodiments, one or more of the holes 309 do not extend through the grip 300 (e.g., from the outer surface 305 toward the inner surface 306). In some embodiments, the holes 309 are distributed across the entire grip 300. In other embodiments, the holes 309 are distributed across one or more sections of the grip and one or more other sections of the grip do not have holes distributed thereon. In one particular embodiment, the holes 309 have a diameter of 0.0625 inches, a depth of 0.0195 inches, and/or an edge-to-edge spacing of 0.0625 inches.

[077] In some embodiments, the holes 309 can be evenly or uniformly distributed on the one or more sections of the grip in which the holes are formed. In other embodiments, the holes can be unevenly or non-uniformly distributed on the one or more sections of the grip in which the holes are formed.

[078] FIGS. 8-11 depict a grip 400, according to one embodiment. The grip 400 is configured similar to the grip 300, except that the grip 400 only has an opening at one end rather than lumen extend all the way through the grip like the grip 300.

[079] The grip 400 comprises a longitudinal axis 401, a transverse axis 402, a bottom terminus 403, a top terminus 404, an outer surface 405, and an inner surface 406 defining an opening 407 formed in the top terminus 404 and having an inner diameter consistent across the opening 407.

[080] The outer surface 405 of the grip 400 comprises a primary slanted region 408 having an apex 409 near the bottom terminus 403 of the grip 400 and a nadir 410 near the top terminus 404 of the grip 400. The diameter of the opening 407 is large enough so that the grip 400 may be placed over the handle of a bat.

[081] The primary slanted region 408 comprises an angle having a vertex and comprised of a first ray extending from the nadir 410 of the slanted region 408 to the apex 409 of the slanted region 408 and a second ray of the longitudinal axis 401 of the grip 400. The angle can be between 1 and 15 degrees, between 3 and 10 degrees, between 4 and 8 degrees, or between 6-7 degrees. [082] The grip 400 can be used, for example, with a striking implement without a knob. In some embodiments, a manufacturer can mold the grip 400 out of a plastic and place them on a wooden bat machined without a knob using a glue and friction between the handle of the bat and the inner surface 406 of the grip 400.

[083] Additionally or alternatively, a user could cut the knob off a bat and attach the grip 400 in a similar manner. For example, FIG. 12 depicts the bat 200 without the knob 208 (see FIG. 4) and with the grip 400 attached thereto.

[084] FIGS. 13-16 depict an exemplary embodiment of a grip 500. The grip 500 is configured similar to the grip 400, except the grip 500 further comprises a secondary slanted region 502. The secondary slanted region 502 is disposed between a bottom terminus 504 of the grip 500 and an apex 506 of a primary slanted region 508. The secondary slanted region 502 can be used, for example, to approximate the familiar sensation of gripping a striking implement with a knob and/or to serve as a tactile indicator of the implement's bottom terminus.

[085] FIGS. 17-21 depict a grip 600, according to another embodiment. The grip 600 comprises a longitudinal axis 602, a bottom terminus 604, a top terminus 606, an outer surface 608, and an inner surface 610 defining an opening 612 formed in the top terminus 606.

[086] The outer surface 608 of the grip 600 comprises a primary slanted region 614 and a secondary slanted region 616. The primary slanted region 614 has a nadir 618 adjacent the top terminus 606 of the grip 600 and an apex 620 near the bottom terminus 604 of the grip 600. The primary slanted region 614 can comprise an angle of 1-15 degrees, 3-10 degrees, 4-8 degrees, or 6- 7 degrees relative to the longitudinal axis 602 of the grip 600. The secondary slanted region 616 has a nadir 622 at the apex 620 of the primary slanted region 614 and an apex 624 toward the bottom terminus 604 of the grip 600.

[099] FIG. 25 depicts a grip 900, according to another embodiment. In some embodiments, the grip 900 can be configured similar to the grip 600. The grip 900 comprises an opening 902 formed in an end of the grip. The opening 902 can be configured for receiving a handle portion of a striking implement.

[0100] In some embodiments, the opening 902 can have an ovular shape taken in a plane perpendicular to a longitudinal axis of the opening. Configuring the grip 900 with an ovular opening 902 can, for example, allow the grip 900 to be used with striking implements having ovular handles (e.g., hurling sticks and/or field hockey sticks).

[0101] The opening 902 can comprise various dimensions and can be adapted for various applications. The opening 902 can include a major axis Ai and a minor axis A₂. In some embodiments, the major axis Ai can have a length of 0.5-2.5 inches, and the minor axis A₂ can have a length of 0.25-2.0 inches. In one particular embodiment, the major axis Ai can have a length of 1.1875 inches, and the minor axis A₂ can have a length of 0.75 inches.

[0102] FIG. 26 depicts a grip 1000, according to another embodiment. In some embodiments, the grip 1000 can be configured similar to the grip 600. The grip 1000 comprises an opening 1002 formed in an end of the grip. The opening 1002 can be configured for receiving a handle portion of a striking implement.

[0103] In some embodiments, the opening 1002 can have a rectangular shape taken in a plane perpendicular to a longitudinal axis of the opening. Configuring the grip 1000 with a rectangular opening 1002 can, for example, allow the grip 1000 to be used with striking implements having rectangular handles (e.g., hockey sticks).

[0104] The grip 1000 can comprise various dimensions and can be adapted for various

applications. The grip 1000 can include widths Wi, Wn, Wm, and Wiv. In some embodiments, Wi can be 0.5-3 inches, Wn can be 0.5-3 inches, Wm can be 0.5-3 inches, and/or Wrv can be 0.5-3 inches. In one particular embodiment, Wi can be 0.938 inches, Wn can be 1.313 inches, Wm can be 0.875 inches, and/or Wrv can be 1.25 inches.

[0105] FIG. 27 depicts an exemplary embodiment of a grip 1100. The grip 1100 can comprise a first portion 1102 and a second portion 1104. The first portion 1102 can be configured for a user's non-dominant hand to be placed thereon. The second portion 1104 can be configured for the user's dominant hand to be placed thereon.

[0106] In certain embodiments, the first portion 1102 can be configured similar to the grip 600.

[0107] The second portion 1104 can taper radially outwardly from the location at which the first and second portions meet. For example, the second portion 1104 can have a generally frustoconical shape taken in a plane parallel to a longitudinal axis of the grip 1100. In this manner, the first and second portions 1102, 1104 collectively form a "bow-tie" or "V" shape taken in a plane parallel to a longitudinal axis of the grip 1100. This shape can, for example, create a centripetal force which urges the user's hands together when a user swings the striking implement to which the grip is attached. This can, for example, reduce the likelihood that the implement will unintentionally fly out of the user's hand, which in turn can reduce injuries to players, fans, and/or bystanders.

[0108] The degree of taper of the second portion 1104 can vary. In some embodiments, for example, the second portion 1104 can be tapered 1-30 degrees, 10-20 degrees, or 12-15 degrees relative to a longitudinal axis of the grip 1100. [0109] FIG. 28 depicts an exemplary embodiment of a grip 1200. The grip 1200 can comprise a first portion 1202 and a second portion 1204. The first portion 1202 can be configured for a user's non-dominant hand to be placed thereon. The second portion 1204 can be configured for the user's dominant hand to be placed thereon.

[0110] In some embodiments, the first portion 1202 can be configured similar to the grip 600.

[0111] The second portion 1204 can have an arcuate or semi-oval cross-sectional profile taken in a plane parallel to a longitudinal axis of the grip 1200. The asymmetrical shape of the second portion 1204 can be configured to better match the shape of a user's hand when wrapped around the handle of the striking implement. This can, for example, improve the ergonomics of a striking implement to which the grip 1200 is attached and can also increase power and efficiency of the user.

[0112] In particular embodiments, a grip (e.g., the grips 100, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200) can comprise an opening (e.g., the opening 612, 710, 802, 902, 1002) that has a plurality of sections. Each section can comprise a different cross-sectional profile taken in a plane perpendicular to the longitudinal axis of the opening. For example, in one particular embodiment, the opening can comprise a first section with an ovular cross-sectional profile and a second section having a circular cross-sectional profile. Such embodiments can be used, for example, with striking implements that have various cross-sectional profiles, such a field hockey stick that has a circular cross-sectional profile at a first end of the stick and an ovular cross-sectional profile at an intermediate portion of the stick.

[0113] The grips disclosed herein can be formed from various materials. For example, in some embodiments, a grip can be formed of a material capable of being stretched, such as a rubber, and/or may be made of a rigid material such as a hardened plastic or wood. In one particular embodiment, the grip comprises ethylene propylene diene monomer ("EPDM").

[0114] The disclosed grips can also have various surface textures such as smooth, perforated, knurled, and/or ribbed. Additionally or alternatively, the grips can include indentations in which the user' s fingers can rest.

[0115] The grips disclosed herein can, for example, facilitate a user holding a striking implement at an angle between 95°-120°, between 100°-115°, or between 108°-110° (e.g., 109°) relative to their non-dominant forearm while their wrist is in its neutral position and in alignment with their forearm. The angles disclosed herein can be adapted to ensure a neutral wrist position for other sports and/or activities. By facilitating a neutral wrist position, the disclosed grips can, for example, increase the user's comfort, lessen the possibility of injury, and/or increase the power capable of being transferred to the ball or object being struck, thrown, etc. [0116] Additionally, the disclosed grips can be adapted for use with nearly any type of handle.

[0117] The technologies from any example can be combined with the technologies described in any one or more of the other examples. For example, one or more of the technologies described with respect to the grip 100 can be combined with one or more of the technologies described with respect to the grip 600, or vice versa. As another example, the technologies of the grip 300 can be combined with one or more of the technologies of the grip 1100, or vice versa.

[0118] In view of the many possible embodiments to which the principles of the disclosure may be applied, it should be recognized that the illustrated embodiments are only preferred examples and should not be taken as limiting the scope of the claims.
