the present invention accordingly provides for a system and method to re - grip golf clubs utilizing a series of systematically weighted grips used to balance the swing weight of a golf club . a standard grip is usually about 50 grams ( on average ). the series of weighted grips may be provided in 5 gram increments from 25 to 60 grams in weight . the user may , however , choose to be more exact and implement grips with 2 or 3 gram increments if necessary . the present system allows the exact swing weight of a club to be determined based on the grip weight . the relationship is such that , as the grip is lightened , the heavier the swing weight will be . as weight is added to the grip end the swing weight will be decreased . this system allows the player to achieve a desired swing weight without undue and tedious trial and error . as an example , when a player shortens a club , for every one inch the club is shortened the club will lose about 5 swing weights , depending on shaft weight and club head design . swing weight in golf is an indication of how “ heavy ” a club head feels in a golfer &# 39 ; s hands . it is a golf specific scale that commonly is measured in terms of a , b , c , d , e and f weights and numerical numbers from 1 - 9 for each alphabetic denomination . the most common weights are in the c and d weight range . in the past , players have had to use lead tape to try and maintain the same swing weight of a club before the club is shortened . it was messy and awkward as to where to put the tape on the head and it added to the overall weight of that club . as an example , if a player shortens a driver half of an inch about 2 swing weights are lost . if the club had a 50 gram grip and the club is d2 before the half inch was cut off , a 45 gram grip according to the invention can be used to regain 2 swing weights and balance the club back to d2 . if we would like an even heavier swing weight , of say d4 , one can use a 40 gram grip and achieve a desired d4 swing weight . similarly , if the player wishes to lighten a swing weight from d2 to d0 , a 55 gram grip can be used to lose 2 points and come out to d0 if so desired . note the user optionally may choose 2 or 3 gram intervals to provide even more precise weighting . referring to fig2 , for a conventional rubber grip 10 the invention can use a series of circular air pockets 20 within the grip that will control the weight . the larger the air pockets the less rubber is needed and the lighter the grip will weigh . it may be graduated from small pockets on the 45 gram grip and get larger 30 as the grip gets lighter , as illustrated in fig2 and 3 . the 25 gram grip will have the largest air pockets and the 50 , 55 and 60 gram grips could be solid rubber . another means of achieving this result would be to use lighter rubber compounds to make the grip . for a multi - layer grip the invention can adjust the weight by controlling the under listings weight in 5 gram intervals since the outer layer will always remain constant . an under listing is a smaller version of a rubber grip that has an outer layer already attached to it . a presently preferred embodiment fitting system provides one “ fitting grip ” 30 of each of the 8 different gram weighted grips ( 25 , 30 , 35 , 40 , 45 , 50 , 55 and 60 grams ). as illustrated in fig4 , the grip will be cut 32 or manufactured with a cut or void allowing the grip to be put on the bare shaft 12 and can be checked for balance along one entire side lengthwise so that the player can attach one of the desired “ fitting grips ” 30 on to the end of the shaft to see what the swing weight will become . note : the addition of one wrap of “ two way ” tape that is used to adhere the grip to the shaft will decrease the swing weight about 1 swing weight . this “ fitting grip ” will take much of the guess work out of golf club assembly , particularly when the total length and swing weight are to be substantially altered , and to make sure the swing weight comes out correctly without having to use time consuming trial assembly and disassembly calculations . referring to fig4 a , the invention may use different end cap numbers , colors or paint fills 40 on the top of the grips of these “ same design and looks ” grips to differentiate the grips in an easy to use system of end cap colors or perhaps different color paint fill on the butt end of the grip to differentiate the weights of the grips and make them easier to work with and keep separated at the retail level . in one aspect of the invention , for example , we may choose red end caps or paint fill to equal the 25 gram grips , blue end caps or paint fill to equal 30 gram grips and white end caps or paint fill to equal 35 gram grips etc ., so customers and staff will know immediately the weights of each grip in this “ end cap color or paint fill color coded system .” the user may also choose to make the entire grip in specific colors in a color coded system to represent the different weighted grips . for example , we may chose red grips to equal the 25 gram grips , blue to equal 30 gram grips and white to equal 35 gram grips etc ., so customers and staff will know immediately the weights of each grip in this “ entire grip color specific system .” such a system of color coding would be particularly useful for test grips of the method of this invention . there can also be midsize and oversize versions available for the grips of the invention along with putter grips to achieve the head weight / swing weight the player desires . in order to make the grips in those weights described above , the grips should be lighter than the traditional standard weighted grips that are generally around 50 grams . in order to achieve this , the invention can use lighter weight materials to be used in multi - layered grips or a series of voids within the grips for “ traditional ” rubber - type grips . how it is exactly done will be done in the well - known manufacturing process of the grips by the companies who manufacture them . as illustrated in fig5 , both the fitting grip 30 and final installed grip 60 may make use of a further weighting element 50 . as shown in fig5 a , weighting element 50 may be threaded into the grips by threads 52 on the cap weight 50 mating to similar threads in grip 34 as desired and with extended weight 54 to vary in a more vernier fashion the swing weight and distribution of weight in the grip . from the above , it may be seen by those skilled in the art of club assembly and repair that the present invention represents important advantages over previous systems .
a system and method to re - grip golf clubs includes a series of systematically weighted golf club grips used to achieve a desired swing weight of a golf club . a series of interchangeable weighted tubular fitting grips having a sequence of systematically varying predetermined weights can be removably mounted on a golf club , as desired , to provide the desired swing weight . the tubular fitting grips each have a void through a length of one side of a tubular outer wall allowing each grip to be interchangeably mounted on the golf club .
