TEXTURIZED GOLF GRIP SURFACES

Abstract

A golf grip comprising two texturized surface patterns formed by outward-extending resiliently pliable protrusions. The first texturized surface pattern encircles an upper portion while the second texturized surface pattern encircles a lower portion of the golf grip. A border region separates the two texturized surface patterns. The border region defines an elongate tongued shape of the first texturized surface pattern extending along the top surface of the golf grip from its butt end and further defines an elliptical wave shape receding toward the butt end of the golf grip the opposite side surfaces of the golf grip. The two texturized surface patterns may be identical wherein each texturized surface pattern comprises a plurality of rows of equidistantly spaced-apart globular protrusions extending outward from the golf grip, each of the rows offset from its adjacent rows whereby the spaced-apart globular protrusions form a honeycomb pattern.

Description

TECHNICAL FIELD

This disclosure relates to grips for golf clubs and putters. More specifically, this disclosure pertains to golf grips having raised textured patterns for improved gripping and grip alignment.

BACKGROUND

Golf is a popular but not easy sport engaged by a large number of professional players on a number of global tours. Additionally, golf is particularly popular as a recreational activity around the world. There have been many improvements to golf clubs and putters to improve their playability by amateurs, i.e. to enable amateurs to increase their enjoyment of the game by shooting lower scores.

A successful golf swing requires a golfer to controllably coordinate a variety of twisting and turning biomechanical movements of their torso, hips and shoulders from the beginning of a stroke to the end of a stroke. Prior to commencing a golf swing, the golfer must grip a selected golf club with both hands which requires separate alignment of the fingers and thumb on each hand around the golf grip in reference to the face of the golf club, and then once the grip of each hand is set, adjust the pressure exerted by the hands around the grip. Then, the golfer must maintain a constant pressure on the grip with both hands from the beginning of the swing to the end of the swing. Right-handed golfers typically grip a golf club with their left hand at the top of the golf grip on the golf shaft with the left thumb resting on the top surface of the golf grip or alternatively, just off the top on the upper right side of the golf grip, while their left fingers encircle and apply a selected pressure to the grip. Then, the palm of their right hand is placed over the left thumb with the right thumb overlapping the left thumb and the right fingers encircle and apply a selected pressure to the grip. Left-handed golfers grip a golf club in a similar manner except their right hand is at the top of the golf grip and the palm of the left hand is placed over the right thumb.

Most amateur golfers have many problems with properly positioning their hands on a golf grip, and then aligning their grip with the face of the club before they commence their swing, so that they are able to hit a straight golf shot, and if they are somewhat skilled, a shaped golf shot during execution of their golf swing. For example, a strong grip which is characterized by the “V's” formed by compressing the thumb against the index finger of each hand for a right-handed golfer, pointing to their right shoulder typically results in a hooked shot to the left. A weak grip for a right-handed golfer characterized by the “V's” of the left hand pointing toward the golfer's chest or left shoulder typically results in sliced shots to the right. Problems caused by mis-alignment of the golfer's hands on the golf grip are exacerbated by mis-alignment of the club face to the ball. For example, an open face occurs when the toe of the club face is behind the heel of the club face when the ball is addressed, while a closed face occurs when the of the club face is behind the heel of the club face when the ball is addressed. An open club face during a golf swing typically results in the golf ball flying significantly to the right of the target, while a closed club face during a golf swing typically results in the golf ball flying significantly to the left of the target. A weak grip combined with an open face during the swing causes a slicing ball flight farther to the right than typically occurs when only one of the two alignment problems is manifest. Likewise, a strong grip combined with closed face during the swing causes a hooking ball flight farther to the left than typically occurs when only one of the two alignment problems is manifest.

Other problems encountered by amateur golfers relate to the tactile sensations they experience in the contact between their hands and golf grips during their setup while addressing a golf ball, and then during their golf swing. There have been numerous innovations to improve the “tackiness” or “stickiness” of golf grips to prevent the golf club from slipping in the golfer's hands during a swing, and to provide feedback on maintaining a certain selected grip pressure through the execution of a golf swing. However, the problems still remain with the known golf grip innovations with regarding to assisting a golfer to properly align their hands and grip pressure during their golf shot set up, and for balancing the pressures applied by each of their hands onto the golf grip.

SUMMARY

The exemplary embodiments of the present disclosure generally relate to golf grips having two textured patterns encircling the circumference of the grips in a pattern wherein the first textured pattern extends downward along the grip from its butt end and the second textured pattern extends upward along the grip from its shaft-receiving end. The two textured patterns are separated by an asymmetrical tongue-shaped band extending downward about the circumference of the grip from its butt end that provides a golfer a visual reference plus a tactile reference for repeatedly positioning their upper hand, thumb and fingers on and about the first textured pattern in a selected position, and for repeatedly positioning their lower hand, thumb and fingers on and about the second textured pattern in a position complementary to the selected position for the upper hand.

According to one aspect, the first texturized pattern at the top of the grip comprises a series of raised elongate protrusions extending outward from grip surface in a repeating herringbone-type pattern around the circumference of the upper portion of the grip. The second texturized pattern comprises a series of raised approximately circular protrusions extending outward from the grip surface around the bottom portion of the grip in a plurality of off-set rows. The two texturized patterns abut a border region that extends the first texturized pattern downward along the top surface portion of the grip, extends the second texturized portion upward along the bottom portion of the grip, and provides a downward-extending elliptical profile along the sides of the grip from its upper surface to its lower surface.

According to another aspect, an exemplary texturized grip may comprising a pliable resilient material exemplified by polyurethane that may be adhered to a core material forming the grip profile. Suitable core materials are exemplified by ethylene-vinyl acetate compositions, rubber compositions, and the like.

According to another aspect, the texturized grip surfaces disclosed herein are suitable for producing grips for receiving and engaging the shafts of putters.

DETAILED DESCRIPTION

The exemplary embodiments of the present disclosure generally relate to golf grips having two textured patterns encircling the circumference of the grips in a pattern wherein the first textured pattern extends downward along the grip from its butt end and the second textured pattern extends upward along the grip from its shaft-receiving end. The two textured patterns are separated by an asymmetrical tongue-shaped band extending downward about the circumference of the grip from its butt end that provides a golfer a visual reference plus a tactile reference for repeatedly positioning their upper hand, thumb and fingers on and about the first textured pattern in a selected position, and for repeatedly positioning their lower hand, thumb and fingers on and about the second textured pattern in a position complementary to the selected position for the upper hand. The tongue element of the band is positionable along the top surface of the proximal end of a shaft inserted into the grip so that the downward-extending tongue element is squared to the bottom-leading edge of a club head engaged with the distal end of the shaft. The two textured patterns in combination with the asymmetrical tongue-shaped band provide a golfer a visual reference plus a tactile reference for repeatedly positioning their upper hand, thumb and fingers on and about the first textured pattern in a selected position, and for repeatedly positioning their lower hand, thumb and fingers on and about the second textured pattern in a position complementary to the selected position for the upper hand. For example, a golfer would place the thumb of their upper hand extending downward on top of the tongue-shaped element while their fingers encircle the grip with one or more of the finger tips touching the asymmetrical band. After some experimentation and practice with positioning the thumb and fingertips of their upper hand on the grip prior to hitting practice golf balls, the golfer will have an understanding of how to shift the positioning of their upper thumb and fingertips in reference to the visual cues provided by the asymmetrical band to, for example, precisely open or alternatively close the clubface prior to swinging and hitting a golf ball.

FIG. 4(B) is a cross-sectional view of an alternative exemplary lower texturized pattern.

The grip 10 is provided with an orifice (not shown) at its lower end for receiving therethrough and demountably engaging therein the shaft 5 of a golf club (not shown). The opposite top end of the grip 10, also commonly referred to as the “butt end”, is provided with an end cap 18.

An exemplary first texturized surface pattern 12 encircling the upper portion of the grip 10 is provided with a plurality of rows of side-by-side elongate protrusions 24 extending outward from the surface 22 of the grip 10 (FIGS. 3(B), 4(A)). Each row of the side-by-side elongate protrusions 24 runs parallel to the longitudinal axis of the grip 10 from the top of the grip 10 to the border region 16. The side-by-side elongate protrusions 24 in each row are equidistantly spaced apart from each other and are offset from perpendicular by the same angle, for example by 2.5°, 5°, 7.5°, 10°, 12.5°, 15°, 17.5°, 20°, 22.5°, 25°, 27.5°, 30°, 32.5°, 35°, 37.5°, 40°. Each elongate projection is slightly inwardly inclined as it projects upward, for example by 1°, 1.25°, 1.5°, 1.75°, 2.°, 2.25°, 2.5°, 2.75°, 3°. Each row of side-by-side elongate protrusions 24 is offset from its adjacent rows to form a herringbone pattern running from the top of the grip 10 toward its lower portion, for example by 2.5°, 5°, 7.5°, 10°, 12.5°, 15°, 17.5°, 20°, 22.5°, 25°, 27.5°, 30°, 32.5°, 35°, 37.5°, 40°. The elongate protrusions 24 extend outward equidistantly from the grip surface 22, for example by about 0.25 mm, 0.5 mm, 0.75 mm, 1.0 mm. Each of the elongate protrusions 24 is spaced from its adjacent elongate protrusions 24 by about 0.25 mm, 0.5 mm, 0.75 mm, 1.0 mm, 1.25 mm, 1.5 mm.

It is optional, if so desired, for a modification of the first texturized surface pattern (not shown), to have the ends of the side-by-side protrusions 24 of one row joined to the ends of an adjacent row of side-by-side protrusions 24 to form a single row with a series of V-shaped protrusions extending from the top of the grip toward its lower portion. In this modified pattern, the texturized herringbone surface pattern would comprise a plurality of adjacent spaced-apart rows of side-by-side V-shaped protrusions. Alternatively, if so desired, the ends of the side-by-side protrusions 24 of one row joined to the ends of an adjacent row of side-by-side protrusions 24 to form a single row with a series of inverted V-shaped protrusions extending from the top of the grip toward its lower portion. Alternatively, if so desired, both ends of the side-by-side protrusions 24 of one row to the ends of the side-by-side protrusions 24 of two adjacent rows of protrusions to form a zig-zag pattern running from the top portion of the grip toward the bottom portion.

An exemplary second texturized surface pattern 14 encircling the lower portion of the grip 10 is provided with a plurality of rows of a plurality of side-by-side approximately globular protrusions 26 extending upwards from the surface 22 of the grip 10 (FIG. 4(B)). Each row of plurality of globular protrusions 26 is positioned to fit into about the junctures of the plurality of circular protrusions 26 in the rows on either side of the row, to form a “honeycomb” appearance. As shown in FIG. 3(D), the globular protrusions 26 may be hexagonal in shape. Alternatively, if so desired, the globular protrusions 26 may be pentagonal, heptagonal, octagonal, nonagonal, decagonal, hendecagonal, dodecagonal in shape. Each globular protrusion 26 may be slightly inwardly inclined as it projects upward, for example by 1°, 1.25°, 1.5°, 1.75°, 2.°, 2.25°, 2.5°, 2.75°, 3°. Alternatively, the globular protrusions 26 may be a circular globe or dome or alternatively, an elliptical dome. Such globe-shaped and dome-shaped and elliptical dome-shaped protrusions are also referred to herein as “reverse dimples”. The globular protrusions 26 extend outward equidistantly from the grip surface 22, for example by about 0.25 mm, 0.5 mm, 0.75 mm, 1.0 mm. Each of the elongate protrusions 26 is spaced from its adjacent elongate protrusions 24 by about 0.25 mm, 0.5 mm, 0.75 mm, 1.0 mm, 1.25 mm, 1.5 mm.

The border region 16 abutted by the first texturized surface pattern 12 and the second texturized surface pattern 14 forms a tongue-shape extending downward along the top of the grip 10 from its upper portion to its bottom portion (FIGS. 1, 3(A)) with a wave-shaped elliptical pattern extending along the sides of the grip 10 from the tip of the “tongue” formed by the first texturized surface pattern 12 on the top of the grip 10 toward the top of the grip 10 (FIGS. 1, 2(A), 2(C)). The border region 16 (also visible in FIG. 3(C)) comprises the surface 22 of the grip 10 between the first texturized surface pattern 12 and the second texturized surface pattern 14. The width of the border region may be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 7.5 mm, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm.

It is also optional, if so desired, for the first texturized surface pattern to comprise a plurality of rows of a plurality of side-by-side approximately globular protrusions 26 extending upwards from the surface 22 of the grip 10 (FIG. 4(B)). Each row of plurality of globular protrusions 26 is positioned to fit into about the junctures of the plurality of circular protrusions 26 in the rows on either side of the row, to form a “honeycomb” appearance. As shown in FIG. 3(D), the globular protrusions 26 may be hexagonal in shape. Alternatively, if so desired, the globular protrusions 26 may be pentagonal, heptagonal, octagonal, nonagonal, decagonal, hendecagonal, dodecagonal in shape. Each globular protrusion 26 may be slightly inwardly inclined as it projects upward, for example by 1°, 1.25°, 1.5°, 1.75°, 2.°, 2.25°, 2.5°, 2.75°, 3°. Alternatively, the globular protrusions 26 may be a circular globe or dome or alternatively, an elliptical dome. The globular protrusions 26 extend outward equidistantly from the grip surface 22, for example by about 0.25 mm, 0.5 mm, 0.75 mm, 1.0 mm. Each of the elongate protrusions 26 is spaced from its adjacent elongate protrusions 24 by about 0.25 mm, 0.5 mm, 0.75 mm, 1.0 mm, 1.25 mm, 1.5 mm.

Another exemplary embodiment of a cylindrical grip 100 according to the present disclosure is illustrated in FIGS. 5(A), 5(B) wherein grip 100 is provided with an orifice (not shown) at its lower end for receiving therethrough and demountably engaging therein the shaft 5 of a golf club (not shown). The opposite top end of the grip 100, also commonly referred to as the “butt end”, is provided with an end cap 18. The golf grip 100 comprises two sets of the same texturized surface pattern 14 (FIGS. 4(B), 5(A), 5(B)) separated by a border region 16 that is interposed the two sets of texturized pattern 14 to form a tongue-shape extending downward along the top of the grip 100 from its upper portion to its bottom portion (FIG. 5(B)) with a wave-shaped elliptical pattern extending along the sides of the grip 10 from the tip of the “tongue” formed by the first texturized surface pattern 12 on the top of the grip 100 toward the top of the grip 10 (FIG. 5(A)). The border region 16 comprises the surface 22 of the grip 10 between the first set of texturized surface pattern 14 and the second set of texturized surface pattern 14. The width of the border region 16 may be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 7.5 mm, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm. In reference to FIG. 4(B), each set of texturized pattern 14 comprises a plurality of rows of a plurality of side-by-side approximately globular protrusions 26 extending upwards from the surface 22 of the grip 10. Each row of plurality of globular protrusions 26 is positioned to fit into about the junctures of the plurality of circular protrusions 26 in the rows on either side of the row, to form a “honeycomb” appearance. As shown in FIGS. 5(A), 5(B), the globular protrusions 26 may be hexagonal in shape. Alternatively, if so desired, the globular protrusions 26 may be pentagonal, heptagonal, octagonal, nonagonal, decagonal, hendecagonal, dodecagonal in shape. Each globular protrusion 26 may be slightly inwardly inclined as it projects upward, for example by 1°, 1.25°, 1.5°, 1.75°, 2.°, 2.25°, 2.5°, 2.75°, 3°. Alternatively, the globular protrusions 26 may be a circular globe or dome or alternatively, an elliptical dome. Such globe-shaped and dome-shaped and elliptical dome-shaped protrusions are also referred to herein as “reverse dimples”. The globular protrusions 26 extend outward equidistantly from the grip surface 22, for example by about 0.25 mm, 0.5 mm, 0.75 mm, 1.0 mm. Each of the elongate protrusions 26 is spaced from its adjacent elongate protrusions 24 by about 0.25 mm, 0.5 mm, 0.75 mm, 1.0 mm, 1.25 mm, 1.5 mm. The border region 16 comprises the surface 22 of the grip 10 between the first set of texturized surface pattern 14 and the second set of texturized surface pattern 14. The width of the border region 16 may be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 7.5 mm, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm.

The base diameter of the each globular protrusion in the first set of texturized pattern 14 is about the same as the other globular protrusions in the second set of texturized pattern 14. The diameters of the globular protrusions in the first set of texturized pattern 14 may be the same as the diameters of the globular protrusions in the second set of texturized pattern 14. Alternatively, the diameters of the globular protrusions in the first texturized pattern 14 may be the larger than the diameters of the globular protrusions in the second texturized pattern 14. Alternatively, the diameters of the globular protrusions in the first set of texturized pattern 14 may be the smaller than the diameters of the globular protrusions in the second set of texturized pattern 14. The globular protrusions in the first set of texturized pattern 14 may extend outward farther from the grip surface than the globular protrusions in the second set of texturized pattern 14, for example by about 0.25 mm, 0.5 mm, 0.75 mm, 1.0 mm. Alternatively, the globular protrusions in the second set of texturized pattern 14 may extend outward farther from the grip surface than the globular protrusions in the first set of texturized pattern 14, for example by about 0.25 mm, 0.5 mm, 0.75 mm, 1.0 mm. It is optional for the globular protrusions in the first set of texturized pattern 14 to be less resiliently pliable (i.e., “stiffer”) than the globular protrusions in the second set of texturized pattern 14. Alternatively, the globular protrusions in the second set of texturized pattern 14 may be less resiliently pliable (i.e., “stiffer”) than the globular protrusions in the first set of texturized pattern 14.

The two sets of texturized pattern 14 may be globular protrusions in the form of reverse dimples or alternatively may be pentagonal, heptagonal, octagonal, nonagonal, decagonal, hendecagonal, dodecagonal in shape. The shapes and heights of the globular protrusions may be identical in both sets of texturized pattern 14. Alternatively, while the general shape of the globular protrusions may be similar, the globular protrusions in one set of texturized pattern 14 may have larger base diameters than the globular protrusions in the other set of texturized pattern 14 whereby the globular protrusions with the wider bases will have larger top surfaces than the globular protrusions with the wider bases thereby providing two different types of “feel” (i.e., tactile sensations) when gripped with two hands. Similarly, one set of globular protrusions may extend outward from the base surface of the grip about 0.5 mm, 1.0 mm, 1.5 mm, 2.0 mm, 2.5 mm than the other set of globular protrusions thereby providing two different types of “feel” (i.e., tactile sensations) when gripped with two hands.

Another example of two sets of the same texturized pattern abutting the asymmetrical tongue-shaped band may comprise a plurality of side-by-side equidistantly spaced-apart elongate protrusions forming a herringbone pattern 12 as described above and illustrated in FIGS. 1-3. The shapes and heights of the elongate protrusions may be identical in both sets of texturized patterns. Alternatively, while the general shape of the elongate protrusions may be similar, the elongate protrusions in one of the texturized patterns may have larger base diameters than the elongate protrusions in the other of the texturized patterns whereby the elongate protrusions with the wider bases will have larger top surfaces than the elongate protrusions with the wider bases thereby providing two different types of “feel” (i.e., tactile sensations) when gripped with two hands. Similarly, one set of elongate protrusions may extend outward from the base surface of the grip about 0.5 mm, 1.0 mm, 1.5 mm, 2.0 mm, 2.5 mm than the other set of elongate protrusions thereby providing two different types of “feel” (i.e., tactile sensations) when gripped with two hands.

The exemplary texturized golf grips disclosed herein can be produced by stamping the two texturized surface patterns abutting a tongue-shaped border region onto a flat sheet of a selected pliable resilient material, for example as illustrated in FIG. 3(A), and then wrapping and adhering the stamped sheet onto a selected core material forming the grip profile. The two ends of the wrapped texturized material may be glued together forming a seam 17 (FIG. 2(D). Alternatively, as shown in FIG. 6(C), the seam 47 may be stitched together with the texturized patterns “outside in” to form the cylinder which is then unrolled onto and adhered to the core material.

Suitable pliable resilient sheet materials are exemplified by thermoset elastomers and thermoplastic elastomers. In this context, the term “elastomer” refers to polymers that have resiliency properties similar to those of rubber. In particular, the term elastomer reflects the property of the material, in that it can undergo a substantial elongation and then return to its original dimensions upon release of the stress elongating the elastomer. Examples of classes of elastomers suitable for use in connection with forming molded articles include anionic triblock copolymers, polyolefin-based thermoplastic elastomers, thermoplastic elastomers based on halogen-containing polyolefins, thermoplastic elastomers based on dynamically vulcanized elastomer-thermoplastic blends, thermoplastic polyether ester or polyester based elastomers, thermoplastic elastomers based on polyamides or polyimides, ionomeric thermoplastic elastomers, hydrogenated block copolymers in thermoplastic elastomer interpenetrating polymer networks, thermoplastic elastomers by carbocationic polymerization, polymer blends containing styrene/hydrogenated butadiene block copolymers, and polyacrylate-based thermoplastic elastomers. Some specific examples of elastomers are natural rubber, butyl rubber, EPDM rubber, silicone rubber such as polydimethyl siloxane, polyisoprene, polybutadiene, polyurethane, ethylene/propylene/diene terpolymer elastomers, chloroprene rubber, styrene-butadiene copolymers (random or block), styrene-isoprene copolymers (random or block), acrylonitrile-butadiene copolymers, mixtures thereof and copolymers thereof. The block copolymers may be linear, radial or star configurations and may be diblock (AB) or triblock (ABA) copolymers or mixtures thereof. Blends of these elastomers with each other or with modifying non-elastomers are also suitable. Particularly useful is polyurethane.

It is also within the scope of the present disclosure to provide the two texturized surface patterns abutting a tongue-shaped border region on one-piece golf grips by stamping or moulding the two texturized patterns and border region into the other surface of the golf grips. Suitable materials for making such one-piece grips are exemplified by ethylene-vinyl acetate compositions, natural rubber compositions, blends of natural rubbers, blends of natural rubber with ethylene-propylene-diene rubbers (also referred to as “EPDM”), natural rubber-EDPM blends compounded with one or more of hydrated aluminum silicate powder, magnesium carbonate, barium sulfate, calcium oxide, silicon oxide, and the like.

The exemplary texturized golf grips disclosed herein are particularly suitable for installation onto the shafts of golf clubs such as golf irons, hybrid clubs, fairway woods, and drivers wherein the grips 40 are tapered inward from the butt end 48 of the shaft 5 toward the head end of the shaft 5 as illustrated in FIGS. 6(A)-6(C) wherein the tongue-shaped first texturized herringbone surface pattern 42 encircling the upper portion of the grip 40 abuts the second texturized honeycomb surface pattern 44 encircling the lower portion of the grip 40 at the border region 46. The design and layout of the border region 46 in cooperation with the tongue-shaped first texturized herringbone surface pattern 42 and the second texturized honeycomb surface pattern 44 provides reference points for a golfer to set up their golf grip with first their upper hand and followed by their lower hand. A right-handed golfer will first place their left thumb on the top of the tongue of first texturized herringbone surface pattern 42 (e.g., FIG. 6(B) position “a”) and wrap their left fingers around the grip so that their index, middle, ring, and little fingers (i.e., their 1^st, 2^nd, 3^rd, and 4^th fingers) are in contact with or alternatively, abut the “wave-shaped” border region 46 (FIG. 6(A) positions “b”, “c”, “d”, “e” respectively). The right-handed golfer would then place their right palm over their left thumb and wrap their right fingers around the grip. Similarly, a left-handed golfer with begin their setup with their right hand placed about the top of the grip, and once their right hand is engaged, the place their left palm over their right thumb and then engage their left hand with the grip underneath their right hand. The combination of the two textured patterns and the border region will enable a golfer to routinely reproduce the same grip set up, and if so desired, “strengthen” or “weaken” their grip by slightingly rotating the grip in their left hand in reference to the placement of their thumb on the first texturized herringbone surface pattern 42 and its proximity to the border region 46 on the top surface of the grip, and to the proximity of their left fingers to the border region 46 on the side surface of the grip. The pliable resilience of the two texturized surfaces will provide tactile feedback to the golfer regarding the grip pressure they are exerting and will also, reduce the possibility of grip slippage and rotation within the golfer's hands during their execution of a golf swing.

The exemplary texturized golf grips disclosed herein are also particularly suitable for producing putter grips. For example, the two texturized surfaces abutting the tongue-shaped border region can be used to produce non-tapered cylindrical putter grips similar to the exemplary grip 10 shown in FIGS. 2A-3. Alternatively, the two texturized surfaces abutting the tongue-shaped border region can be used to produce putter grips that are tapered inward from the butt end of the putter shaft toward the putter head similar to the exemplary grip 40 shown in FIGS. 5(A)-5(C). Alternatively, the two texturized surfaces abutting the tongue-shaped border region can be used to produce putter grips that are tapered outward from the butt end of the putter shaft toward the putter head as illustrated in FIGS. 6(A)-6(C). A right-handed golfer will first place their left thumb on the top of the tongue of first texturized herringbone surface pattern 62 (e.g., FIG. 6(B) position “a”) and wrap their left fingers around the grip so that their index, middle, ring, and little fingers (i.e., their 1^st, 2^nd, 3^rd, and 4^th fingers) are in contact with or alternatively, abut the “wave-shaped” border region 66 (FIG. 6(A) positions “b”, “c”, “d”, “e” respectively). The right-handed golfer would then place their right palm over their left thumb and wrap their right fingers around the grip. Similarly, a left-handed golfer will begin their setup with their right hand placed about the upper end of the grip with their right thumb extending down on top of the tongue element formed by the top of the tongue of first texturized herringbone surface pattern 62 (e.g., FIG. 6(B) position “a”) and wrap their right fingers around the grip so that their index, middle, ring, and little fingers (i.e., their 1^st, 2^nd, 3^rd ,and 4^th fingers) are in contact with or alternatively, abut the “wave-shaped” border region on the opposite side of the grip mirroring positions “b”, “c”, “d”, “e” respectively shown in FIG. 6(A) and once their right hand is engaged around the grip, then place their left palm over their right thumb and then engage their left hand around the grip underneath their right hand. The combination of the two textured patterns and the border region will enable a golfer to routinely reproduce the same putter set up, and the pliable resilience of the two texturized surfaces will provide tactile feedback to the golfer regarding the grip pressure they are exerting and will also, reduce the possibility of grip slippage and rotation within the golfer's hands during their execution of a golf swing. The reverse taper of this exemplary putter grip (FIGS. 6(A)-6(B)) will assist the golfer to ease up the grip pressure exerted by their lower hand during a putter stroke. Alternatively, a right-handed golfer may wish to begin their setup with their right hand placed about the upper end of the grip with their right thumb extending down on top of the tongue element formed by the top of the tongue of first texturized herringbone surface pattern 62 (e.g., FIG. 6(B) position “a”) and wrap their right fingers around the grip so that their index, middle, ring, and little fingers (i.e., their 1^st, 2^nd, 3^rd, and 4^th fingers) are in contact with or alternatively, abut the “wave-shaped” border region on the opposite side of the grip mirroring positions “b”, “c”, “d”, “e” respectively shown in FIG. 6(A) and once their right hand is engaged around the grip, then place their left palm over their right thumb and then engage their left hand around the grip underneath their right hand. Alternatively, a right-handed golfer may wish to use the “claw” grip wherein their left hand is engaged around the upper end of the grip as described while their right hand is placed below the left hand with the four fingers of their right hand open across the front side of the grip with the base of their forefinger abutting the tip of their left thumb and then wrapping their right thumb around the back of the grip. A left-handed golfer would reproduce the “claw” grip in reverse with their right hand at the upper end of the grip and their left hand abutting the tip of their right thumb and right forefinger.

Another exemplary putter grip 80 according to the present disclosure is shown in FIGS. 8(A)-8(E), wherein the front surface 81 of the grip 80 is flat while the sides and the back of the grip 80 are round. The tongue-shaped first texturized herringbone surface pattern 82 encircles the upper portion of the grip 80 and abuts the second texturized honeycomb surface pattern 84 encircling the lower portion of the grip 80 at the border region 86. The design and layout of the border region 86 in cooperation with the tongue-shaped first texturized herringbone surface pattern 82 and the second texturized honeycomb surface pattern 84 provides reference points for a golfer to set up their putter grip with first their upper hand and followed by their lower hand in reference to the border region 86 as previously described. It is within the scope of the present disclosure to provide different types of end caps at the butt end of the textured grips exemplified herein. For example, a plain end cap such as exemplified by end cap 18 shown in FIG. 1 may be provided. Such plain end caps may be optionally stamped or overlaid with cosmetic designs if so desired. Alternatively, it is optional to provide an end cap that may releasingly engage a ball marker as exemplified in FIGS. 8 and 9 by marker end cap 90. It is preferable that the marker end cap 90 is provided with a retaining rim 92 that extends around at least 55% of the circumference of the marker end cap. If so desired, a magnet 94 may be incorporated into the base of the marker end cap 90 to securely engage metallic markers. Alternatively, the marker end cap 90 may simply be provided with a flat base and have a resilient rim 92 for retaining markers therein.

It is also within the scope of the present disclosure for the exemplary grips to be adapted for securely engaging the shafts of sports equipment wherein alignment of one or both hands around the grip at the butt end of the shaft is a critical element for reproducibly executing desired swing patterns, as exemplified by fishing rods, in particularly fly fishing rods, casting rods and the like, racquets exemplified by tennis racquets, squash racquets, badminton racquets and the like.
