- the present disclosure relates to flexible grips employed on the shaft of a golf club.
- Such grips are typically molded of elastomeric material and have employed various shapes and surface textures for facilitating gripping by the user.
- one of the more important aspects of the use of a golf club is the manner and position in which the user addresses the golf ball with the club prior to initiating the backswing.

All users exhibit personal tendencies at the address position which can place them at a disadvantage due to poor hand position. Furthermore, the inability to achieve a consistent address position leads to variability in the swing that results in improper impact of the club head or blade with the ball resulting in an undesired trajectory of the golf ball.

Abstract
A flexible elastomeric grip for a golf club having indicators on the upper face which indicate visibly to the user when the angle of lie is less than, greater than, and optimum when the user grips the club and addresses the ball. The indicator on its end cap indicates visibly to the user when the angle of lean is neutral or left or right of neutral by at least five degrees (5°). The visible indicator may be either by a changing holographic image or reflective coating. Another version provides a combined angle of lean and angle of lie indicator in an end cap on a flexible grip.
Description
- The present disclosure relates to flexible grips employed on the shaft of a golf club. Such grips are typically molded of elastomeric material and have employed various shapes and surface textures for facilitating gripping by the user. However, one of the more important aspects of the use of a golf club is the manner and position in which the user addresses the golf ball with the club prior to initiating the backswing. If the club is not properly positioned for a given club blade or head, the position of the user's hands on the club will initiate a poorly executed backswing and thus a less than optimum swing path. All users exhibit personal tendencies at the address position which can place them at a disadvantage due to poor hand position. Furthermore, the inability to achieve a consistent address position leads to variability in the swing that results in improper impact of the club head or blade with the ball resulting in an undesired trajectory of the golf ball.
- It has been found that two of the important factors in producing a proper and consistent backswing are the angles of lie and angle of lean of the club upon the golf club being addressed by the user prior to the backswing. The angle of lie is that measured between the club shaft and the horizontal; and, the angle of lean is measured as the lateral angular left or right deviation from an equal angular optimum position of the user's wrists as the club is gripped and the ball addressed. Therefore, it has long been desired to find a way or means of indicating to the user that they have addressed the ball with the club at the optimum angles of lie and lean and in a consistent manner so as to initiate a backswing which will result in a highly repeatable downswing producing the desired ball path as it is related to the players stance and target line for the ball upon impact by the club.
- The present disclosure provides a solution to the above-described problem of indicating to the user the angle of lie and the angle of lean of the club shaft upon the user addressing the ball with the club prior to initiating the backswing. In one version, the present disclosure provides a flexible grip having an indicator on the upper surface of the grip so as to provide a visible indication to the user, after gripping the club and addressing the ball, of the angle of lie of the club shaft. The angle of lie indicator provides a moving image or region of reflection which changes as the angle of lie of the club shaft is varied by the user. If the angle of lie is less than optimum, the user will see a certain image or reflection. If the angle of lie is optimum, the user will see one of a different image or reflection either of which may be in a different location; and, if the angle of lie is greater than optimum, the user will see another image or reflection either of which may be different from the lesser angle of lie image and in a different location on the grip.
- In one version of the lie indicator of the present disclosure, the visible indications to the user may be provided by an insert displaying different holographic images for the different positions of the angle of lie of the club shaft. These holographic images may include moving graphical images, changes in color of the image or different images for different values of angle of lie.
- In another version of the indicator of the lie indication present disclosure, a reflective coating, which may be painted on, is provided on the upper surface of the grip in a manner visible to the user, after gripping the club and addressing the golf ball, in which the paint is reflective in different positions or locations thereon, or in different colors as the angle of lie is varied by the user.
- The grip of the present disclosure may have an end cap and in another version, the lean indicator comprises an insert on the end cap of the flexible grip, with visible images which change to indicate the optimum and left and right deviation from optimum of the angle of lean upon the user gripping the club and addressing the ball.

upper surface 14 of the grip and locatedproximate end cap 18 so as to remain visible to the user when the user has gripped theflexible grip 10 for gripping the club and addressing the golf ball. Theindicator 20 in the present practice may be either of the type employing an insert having a holographic image disposed therein, or the indicator may comprise a surface coating having different reflective properties so as to provide a difference visible image to the user dependent upon the angle of lie denoted alpha (α). In the version shown anFIGS. 1-3 the indicator is of a type having a holographic image; and, as shown inFIG. 1 , theimage 22 is visible in a centrally located position onindicator 20 when the angle alpha (α) is at the optimum shown as seventy-one degrees (71°). Angle alpha (α) may have other values for optimum depending may upon the type of club being employed. - With reference to
FIG. 2 , theholographic image 22 is shown as having moved upwardly in theindicator 20 to a position closer to theend cap 18 when the angle alpha is greater than optimum by at least a predetermined amount, which in the present practice is at least two degrees (2°) as indicated inFIG. 2 where the alpha (α) is seventy-three degrees (73°). Thus, in the present practice, theindicator 20 will cause the image to move to the upper position when the user has gripped the club and addressed the golf ball so that the angle alpha (α) is increased two degrees (2°) from the optimum. - Referring to
FIG. 3 , theholographic image 22 is shown in a position further from theend cap 22 than the neutral portion ofFIG. 1 which represents an angle alpha (α) for theclub shaft 12 less than the optimum by a predetermined amount which in the present practice is an angle of two degrees (2°). Thus,FIG. 3 shows the position of theimage 22 when the club shaft has been gripped by user and addressed the golf ball at angle of lie of sixty-nine degrees (69°). - Referring to
FIG. 4 , another version of the present disclosure, indicated generally at 30, includes a flexible grip of elastomeric material having anupper surface 32 and alower surface 34 and is shown as received onshaft 36 of a golf club with theupper surface 32 oriented to be substantially perpendicular to the face of the club head or blade. Theclub shaft 36 is shown inclined to the horizontal by a lie angle indicated by the designation alpha (α). The angle of lie indicator is indicated generally at 39 and is disposed on thesurface 32 proximate the upper end of the grip which is shown as having anend cap 38. - Referring to
FIG. 5 , one version of the indicator denoted generally at 41, is shown wherein theimage 42, shown in solid line, appears to the user in an upper region of theindicator 41 when the angle alpha (α) is greater than optimum; and,image 42 as shown in dashed line, is moved to a new location lower on theindicator 41 when the alpha is less than optimum. When the angle of lie alpha (α) is optimum, theimage 42 is visible in both locations. Alternatively, theimage 42 may be displayed visible to the user in a central position of the indicator when the angle of lie alpha (α) is at the optimum angle. - Referring to
FIG. 6 , another version of the indicator, denoted generally at 40, is illustrated wherein a series of graphical indicators such as thebars 44 progressively move to different positions and have changing bar lengths on the indicator. In the version ofFIG. 6 , thebars 44 are displayed positioned in the upper portion of the indicator with the maximum length when the angle of lie is greater than the optimum; and, as the angle alpha (α) decreases, and is closer to the optimum, the length of thebars 44 decreases and move toward the center of theindicator 40. When the angle alpha (α) is at the optimum, thebars 44 are shown as having the shortest length and in a central position of theindicator 40. As the angle of lie alpha (α) decreases to less than optimum, the bars appear to the right side of central position, or the lower portion of theindicator 40, and increase in length as the angle of lie is further decreased. Thus, in the version ofFIG. 6 , the user sees a moving bar graph as the angle of lie alpha (α) changes from the user moving the club shaft. - Referring to
FIG. 7 , another version of the indicator, denoted generally at 43, is theimage 46 which comprises text visible in solid line in the upper region of theindicator 43 when the angle of lie alpha (α) is greater than optimum. Theimage 46 appears as shown in dashed line in the lower region of theindicator 43 when the angle of lower alpha (α) is less than the optimum by a predetermined amount, for example, two degrees (2°) less. If desired, the holographic images may be of the type that change colors when the angle of lie alpha changes by the predetermined amount. When the angle of lie alpha (α) is at optimum, both of theimages 46, shown in solid and dashed line, will be visible to the user. - Referring to
FIG. 8 , an alternate version of theindicator FIG. 8 version, the upper third of the indicator denoted 50 is coated with reflective material giving a dark appearance and is indicative of the angle of lie alpha (α) being greater than optimum by a predetermined amount, such, as for example five degrees (5°). When the angle of lie alpha of a club shaft is at an optimum, the user sees the indicator reflected light as is shown incentral region 52 of the indicator inFIG. 8 , which is shown lighter in shade and may be of a different color than theimage 50. When the angle of lie alpha (α) for the club shaft is less than the optimum by the predetermined amount, the user sees thelower region 54 of the indicator as reflecting light in a lighter appearance and may be of another different color. - In the present practice it has been found satisfactory to provide the indicator of
FIG. 8 with a coating having embedded therein reflective particles of different reflective characteristics each of theregion - In the present practice it has been found satisfactory to form the coating with paint comprising a clear paint having multilayered flakes dispersed therein. In the present practice, the coating may combine reflective flakes in multiple layers that provides the ability for the surface to appear to change color when viewed from different angles.

FIG. 9 , another version of the grip of the present disclosure is indicated generally at 60 having anend cap 62 attached to the upper end of the grip with an insert with an indicator which is indicated generally at 64 of the type presenting a holographic image to the user of the club wherein the image visible to the user is varied and depends on the lateral or left-right inclination of the club from a neutral position upon the user gripping the club and possessing the golf ball. As described above, the lateral angle of inclination is referred to as the angle of lean. As discussed hereinabove, it is designed to maintain the club angle of lean in a neutral position as the user grips the club and addresses the ball prior to initiating a backswing. With reference toFIG. 9 , the holographic image visible to the user such as the text letter “G” is displayed in the position left of center as denoted byreference numeral 66 and a second text letter such as “P” indicated by thereference numeral 68, displayed in the position to the right of center, are both visible to the user simultaneously as an indication that the club shaft is in the neutral position. In the present practice, it has been found satisfactory to have bothtext characters - Referring to
FIG. 10 , the indicator 65 is shown with the club shaft having an angle of lean of positive five degrees (5°) representative of the grip being located to the left of the neutral position ofFIG. 9 . In the position of thegrip 60 inFIG. 10 , with a positive angle of lean of at least five degrees (5°), theindicator 64 displays to the user thevisible character 66 in the location left of center of a indicator with thetext image 68 being invisible to the user. - Referring to
FIG. 11 , theindicator 64 displays to the user the holographic image of thecharacter 68 to the right of the center of theindicator 64 for the angle of lean at address to have a value of at least negative five degrees (−5°); and, the lefthand text character 66 remains invisible to the user. The angle of lean (FIG. 11 ) represents the end thegrip 60 moved to the right of the neutral position by at least five degrees (5°). - Referring to
FIG. 12 , another version of the grip of the present disclosure is indicated generally at 70 and is shown attached to theshaft 72 of a golf club. The grip has anend cap 74 on the upper end thereof which cap has an angle oflean indicator 76 disposed on the upper face thereof indicated generally at 76. With reference toFIG. 12 , theindicator 76 displays aholographic image 78 located in the center ofinsert 76 thereby indicating that the club shaft is in the neutral or centered position. - Referring to
FIG. 13 , the holographic image of theindicator 76 has moved to a position left of the center of indicator to be visible to the user indicating that the angle of lean is positive by an amount of at least five degrees (5°). - Referring to
FIG. 14 , the holographic image of theindicator 76 has moved to a position right of the center of indicator, indicating to the user visibly that the angle of lean of the club shaft is at least five degrees (5°) to the right. - If desired, the holographic image may employ characters of different colors or a different colored background changing as the angle of lie or lean changes.
- Referring to
FIG. 15 , another embodiment of the flexible grip of the present disclosure is indicated generally at 80 and is illustrated as received onto ashaft 81 of a golf club. Thegrip 80 has aninsert 82 disposed in the upper or butt end thereof; and, the grip may include anend cap 84 with the insert received in the end cap. The insert includes an indicator which provides visible images to the user, upon gripping the club and addressing the golf ball with the club, of deviations in both the angle of lean and the angle of lie. In the present practice, it has been convenient to employ holographic images in theindicator 82. Theindicator 82 provides animage 86 which is movable in response to deviations in both the angle of lie and angle of lean as will hereinafter be described. For clarity of reference, the line A-A indicates the direction of movement of the club shaft and grip to vary the angle of lie. Thus, it will be understood that variations in the angle of lean are in a direction perpendicular to the line A-A as indicated by the curve line with arrows denoted 85 inFIG. 15 . Movement of the grip in a leftward direction from neutral is indicated as a positive deviation in the angle of lean whereas movement in the rightward direction is indicated a negative deviation in the angle of lean. Similarly, deviation of the angle of lie from a neutral position in an upward direction is denoted as positive deviation in the angle of lie and movement in a downward direction is indicated as a negative deviation in the angle of lie as shown by thecurved line 87 inFIG. 15 . For reference, the direction of the target line or path of the ball is indicated by the dashed line denoted TL inFIG. 15 . - Referring to
FIG. 16 , the position of the uservisible image 86 onindicator 82 is indicated centered on the line A-A thereon and centered with respect to movement at right angles to the line A-A. - Referring to
FIG. 17 , the user visible image has moved to the upper righthand quadrant of theindicator 82 and, in this position, indicates positive deviation in the angle of lie and a negative deviation in the angle of lean. - Referring to
FIG. 18 , the uservisible image 86 is shown in the position in the lower lefthand quadrant of the indicator in which position the indicator shows that the deviation of the angle of lean is positive and the deviation of lie is negative. It will be understood that if the user visible image is in an unshown position in the upper lefthand quadrant of theindicator 82, that such a position would indicate to the user that the angle of lean is positive and the angle of lie is positive. It will further be understood that if the unshownvisible image 86 is in the lower righthand quadrant of theindicator 82, the image would indicate to the user that the angle of lean is negative and that the angle of lie is negative. - The present disclosure describes a flexible grip for golf club having an indicator on the upper face of the grip facing the club head or blade, which visibly indicates to the user upon gripping the club and addressing the ball, whether the angle of lie is in the optimum position or less than or greater than the optimum. The angle of lie indicator may employ a holographic image or reflective material in a coating provided on the upper face of the grip. In another version, an angle of lean indicator is provided on the end cap of the grip. The angle of lean indicator utilizes the holographic image to indicate whether the cap end of the grip is in the neutral position or whether the club shaft is leaning left or right of the neutral. In another version, a combinations indicator is provided on the end cap which indicates to the user deviations from neutral for both the angle of lie and angle of lean.
