[0008] Figure 3 is a schematic view of the placement of the golf club grip of Figure 1 on a golf club.
DETAILED DESCRIPTION
[0009] Generally stated, a golf club grip according to a non-limitative illustrative embodiment of the present invention provide a golf club grip for golfers of all calibers; from amateur to professional. Its principle function is to make griping the golf club easier, maximizing the distance, the trajectory and the distance control of golf shots by providing griping indicators. The griping indicators provide positioning indications to the golfer so that he or she may properly position his or her hands on the grip to effectuate a desired shot. To this end, a method of use of the golf club grip is also disclosed so as to help the golfer in properly positioning his or her hands on the golf club grip.
[0010] Referring to Figure 1 , there is shown a detailed view of a non- limitative illustrative embodiment of the golf club grip 20. The golf club grip 20 comprises five (5) longitudinal indicators, here in the form of lines 31 , 32, 33, 34 and 35 with respective identifiers 41 , 42, 43, 44 and 45 (in this example letters A, B, C, D and E, respectively) and six (6) transversal indicators, here in the form of lines 51 , 52, 53, 54, 55 and 56 with respective identifiers 61 , 62, 63, 64, 65 and 66 (in this example digits 1 , 2, 3, 4, 5 and 6, respectively). It is to be understood that, although lines are used as the longitudinal 31 , 32, 33, 34, 35 and transversal 51 , 52, 53, 54, 55, 56 indicators, other types of indicators may be used as well. It is also to be understood that only longitudinal 31 , 32, 33, 34, 35 or only transversal 51 , 52, 53, 54, 55, 56 indicators may be used.
[0011] Furthermore, in an alternative embodiment, the longitudinal 31 , 32, 33, 34, 35 and/or transversal 51 , 52, 53, 54, 55, 56 lines may further be identified/distinguished by using colors, or the colors may replace the identifiers altogether, for example longitudinal lines 41 , 42 may be colored green, longitudinal line 43 may be colored white, longitudinal lines 44, 45 may be colored red and transversal lines 51 , 52, 53, 54, 55, 56 may be colored orange. It is to be understood that various identifiers may be used to identify the longitudinal 31 , 32, 33, 34, 35 and transversal 51 , 52, 53, 54, 55, 56 lines such as, for example, alphanumeric characters, symbols, textures, colors, embossing, different materials, etc., and that such identifiers may be placed in other locations than those shown in the illustrative embodiment.
[0012] Referring to Figure 2, there is shown an example a typical golf club 10, having a shaft 12 and a head 14, which has been provided with the golf club grip 20. In this example, the golf club 10 illustrated is an iron (as seen by the shape of the head 14). However, it is to be understood that the golf club grip 20 may be provided with or applied to any type of golf club such as, for example, drivers, woods, irons, wedges (pitching (pw), gap (gw), sand (sw), lobe (Iw)) or putters, made of whatever type of material.
[0013] The golf club grip 20 may be provided pre-installed on a golf club, or it may be provided on its own to be used as a replacement grip and placed over the shaft 12 of a golf club whose grip has been removed, as illustrated in Figure 3. It is to be understood that the golf club grip 20 may be provided pre-installed on a complete set of golf clubs or provided in a set of, for example, 15 grips, one for each type of club, to be installed by the user on an existing set of golf clubs. Furthermore, the golf club grip 20 may be designed so as to be applicable to any size of club, for example ladies so-called "56" core, men's so-called "58" core, men's oversize so-called "60" core, etc.
[0014] The golf club grip 20 may be made of, for example, rubber, polyvinyl chloride (PVC), polysulfide rubber (PTR), leather, etc.
[0015] Referring back to Figure 1 , the longitudinal lines 31 , 32, 33, 34 and 35 are indicative of the angle at which the golf club is being held. In the illustrative embodiment lines 31 and 35 are indicative of a 45 degree angle (open grip and closed grip, respectively), lines 32 and 34 are indicative of a 20 degree angle (open grip and closed grip, respectively) and line 33 is the neutral or 0 degree angle. In order to obtain a desired trajectory, lateral effect and distance, the golfer grips the golf club grip 20 so as to align his or her thumbs with the longitudinal line corresponding to the required inclination of the golf club 10. In other words, longitudinal lines 31 and 32 are generally used to produce lateral shots towards the left, longitudinal line 33 for straight shots and longitudinal lines 34 and 35 for lateral shots towards the right. It is to be understood that the angles represented by the longitudinal lines may be different than those specified above and that the number of longitudinal lines may vary depending on the number of desired angles.
[0016] As for the transversal lines 51 , 52, 53, 54, 55 and 56, they are indicative of the amount of grip choke which has an effect on the distance and trajectory of a golf shot. In the illustrative embodiment the transversal lines 51 , 52, 53, 54, 55 and 56 are spaced 1 inch (approximately 2.5 cm) apart from each other but it is to be understood that the number of transversal lines as well as their spacing may vary depending on the desired precision of the grip choke.
Guideline grids [0017] Table 1 shows a tillable guideline grid that may be used in conjunction with the golf club grip 20 in order to allow the golfer to register the distance and trajectory of the golf ball according to the golf club used and precise positioning of his or her hands on the golf club grip 20 as indicated by the longitudinal A, B, C, D, E and transversal 1 , 2, 3, 4, 5, 6 identifiers. Thus, one such table is used for each golf club, identified by the field CLUB. For a given golf club, the observed deflection for each longitudinal line A, B, C, D and E is recorded in corresponding cells identified as defA, defB, defC, defD and defE in Table 1 , respectively. Furthermore, distances obtained for each combination of longitudinal line A, B, C, D, E and transversal lines 1 , 2, 3, 4, 5, 6 are recorded in cells distAI to distEδ.
Figure imgf000007_0001
Table 1 - Fillable guideline grid
[0018] Once a grid has been completed for each golf club, the golfer may then use the completed grids to choose the most appropriate golf club and determine the positioning of his or her hands on that golf club grip 20 to obtain a desired shot distance and trajectory.
[0019] Table 2 shows a computed guideline grid that may be used in conjunction with the golf club grip 20. Unlike the fillable guideline grid of Table 1 , the golfer only registers, for each golf club, the distance obtained for each combination of longitudinal line C (straight shot) and transversal lines 1 , 2, 3, 4, 5, 6, which are recorded in cells distCI to distCβ. The deflection for each longitudinal line A, B, C, D and E is arbitrarily set to 30, 10, 0, 10 and 30, respectively. As for the distances CdistAI to CdistEΘ, these are computed using, for example, the following equations:
CdistAi = distCi x 0.90 ; Equation 1
CdistBi = distCi x 0.95 ; Equation 2
CdistDi = distCi / 0.90 ; Equation 3
CdistEi = distCi / 0.95 ; Equation 4
where i = 1 to 6 (longitudinal lines).
[0020] Equations 1 , 2, 3 and 4 may be solved by the Golfer using, for example, a calculator or the computed guideline grid may be implemented using, for example, an Excel™ spread sheet or any similar software or programming language.
[0021] It is to be understood that other deflection values may be used or that they may also be estimated by equations. Furthermore, Equations 1 , 2, 3 and 4 are given as examples only, other equations may be defined which may take into account the type of club, brand of club, weight of club, material used for the club head, gender and size of the golfer, etc.
