[Embodiment of the invention]

 An embodiment of an improved sleeve type golf club grip according to the present invention will be described below with reference to the drawings. Referring to the drawings, an elongated elastic strip S is utilized to provide the preferred form of the golf club grip of the present invention shown in FIG. The strip S is adapted to be spirally wound around a split sleeve SL attached to the upper portion of a conventional golf club shaft 30 to provide an improved golf club grip as shown in FIG. . The elastic strip S has a fiber layer 40 formed of a suitable open-pore material such as felt, the upper surface of the elastic strip S being adhered to the lower surface of the polyurethane layer 44. As shown in FIG. 4, the polyurethane layer 44 is formed with closed pores 46 extending vertically, that is, substantially perpendicular to the longitudinal axis of the strip S. The pores 46 allow the polyurethane layer to be easily compressed by the gripping force of the golfer's hand. The polyurethane layer 44 is formed by coating one side of the felt strip with a solvent of polyurethane dissolved in dimethylformamide (DMF), such as polyester or polyether, and immersing the coated strip in a water bath to replace the DMF. It can be made by conventional methods by solidifying urethane and finally using water and heat to drive off the water. In this way closed pores 46 are formed, while the lower surface of the polyurethane strip is affixed to the upper surface of the felt layer. To form the closed pores 46, the ratio of the thickness of the polyurethane layer to the thickness of the felt layer should have a minimum value of 0.18. The underside of the felt layer 40 has a conventional adhesive 48 initially covered with a quick release protective tape 50, as shown in FIG. The polyurethane layer 44 absorbs the impact of the player's hand gripping the shaft 30 and also increases the adhesion between the player's hand and the golf club grip as compared to conventional golf club grips. Increase the player's grip. The felt layer 40 provides strength to the polyurethane layer 44 and also acts as a means for attaching the interbonded polyurethane strip and felt strip to the sleeve SL.

Referring now to FIGS. 2 and 3, the outer surface of the polyurethane layer 44 has a plurality of air passages 51 formed in the upper portion thereof. The air passages guide perspiration and moisture into the felt layer 40, further reducing the golfer's hand slip on the grip G. Referring now to Figures 2, 3 and 4, the illustrated strip S is formed with laterally outwardly extending, recessed, reinforced tensile side edges generally indicated at 52 and 54. . The reinforced side edges are formed by a heated platen (not shown) which compresses the outer portion of the side edges of the polyurethane layer below the strip's original outer surface dimensions. The compression increases the strength of the polyurethane layer near the side edges 52 and 54, prevents strips from unraveling from the sleeve, and also enhances the grip grip of the golfer. Referring now to FIGS. 5 and 8-12, a torn sleeve member SL of a golf club grip embodying the present invention is shown. The sleeve SL is of a single synthetic plastic foam or rubber construction utilizing an integral cap 60 that abuts the upper end of the golf club shaft 30. The inner diameter of the sleeve SL should be selected to be a slip fit with the grip receiving portion of the golf club shaft 30 when the sleeve is attached to the golf club shaft 30. A slit 62 extending in the longitudinal direction is formed on one surface of the sleeve SL. It is important to note that the sleeve is secured to the golf club shaft by utilizing the elongated flat adhesive carrier A shown in FIGS. The inner surface of the adhesive carrier A has a flexible body 64 coated on the inner surface with a suitable adhesive 66. The body 64 is coated on its outer surface with an adhesive 68 of the same type. Protective tapes 70 and 72 initially cover the adhesives 66 and 68.

To attach the sleeve SL to the upper end of the golf club shaft 30, the protective tape 70 is first stripped from the adhesive layer of the adhesive carrier A, as shown in FIG. Fixed inside. The protective tape 72 is then stripped from the adhesive 68. The upper end of the golf club shaft is then brought into the area of the sleeve SL by manipulating the sleeve to separate along the slit 62, as shown in FIG. The appearance of the sleeve when attached to the golf club shaft is shown in FIG. The sleeve SL is fixed to the golf club shaft by the adhesive 68. The next step is to wind the strip S onto the sleeve SL. This is achieved by first removing the protective tape 50 from the underside of the strip S. Thereafter, the inclined upper end 74 of the strip S is attached to the upper end of the sleeve SL below the lower surface of the sleeve cap 60. It should be noted that the upper end of the sleeve SL is formed with a recess 76 for receiving the beveled upper end 74 of the strip S. The remainder of the length of the strip S is then spirally wound around the sleeve SL so that the edges of the strip S abut without gaps, as indicated at 78 in FIG. The lower portion of the strip is then secured to the sleeve and golf club shaft by spirally winding a finish tape (not shown) over the golf club shaft. The finishing tape is then preferably covered with a frustoconical protective ferrule (not shown). It should be noted that the strip S can be wrapped around the sleeve SL by the manufacturer to give an attached grip. The mounted grip is then attached to the golf club shaft as a replacement grip by the golfer or a pro shop. Alternatively, the sleeve can be made without slits 62 and this grip can be slip-fitted onto the golf club shaft after the strip has been wrapped around the sleeve as an attached slip-on grip.

The longitudinal contour of the sleeve SL may be the same as the longitudinal contour of the upper portion of the golf club shaft, but with a different longitudinal contour than that of the golf club shaft, for example when the golf club is a putter. It should be noted that it is also possible to use the contour of the sleeve. It should also be noted that the above-mentioned golf club grip embodying the present invention may be used as the first equipment of the golf club or as a substitute for the first golf club grip. Should be.

[Effect of the invention]

 The mounting of the golf club grip of the present invention does not require solvent and tools and can be easily accomplished by an average golfer. Therefore, the golfer does not have to leave the golf club at the golf shop for days to replace its original golf club grip. Also, the cost of replacing the first golf club grip with a golf club grip embodying the present invention is less than the cost of replacing it with a conventional grip. In addition, a golf club grip embodying the present invention allows a golfer to hold the grip firmly even when playing in the rain or when the grip becomes damp due to perspiration formed on the golfer's hand. Can be grasped. Also, the grip of the present invention absorbs more vibrations and shocks than conventional grips, thereby reducing hand fatigue. Therefore, the golfer can continue to hold the grip better than the conventional grip, thereby maintaining better control of the golfer's golf swing. The above control is enhanced by the inherent tackiness of the polyurethane layer of the grip. The golf club grip embodying the present invention also enhances the feel and control of the player during the swing by eliminating the need to wear gloves that protect against skin abrasion.
