Definitions

  • Embodiments of the invention relate to an improved grip for use with the handle portion of articles, in particular, the handle portion of golf clubs.
  • Some embodiments provide a grip configured for use with at least a portion of the handle portion of an article wherein the grip includes an ethylene vinyl acetate sleeve including a first end, a second end, and a mounting surface extending generally therebetween and a gripping member adhered to the mounting surface of the sleeve.
  • the article is a golf club.
  • Some embodiments provide a method of manufacturing a sleeve for use with a grip including the steps of injection molding a primary form of the sleeve in a first mold, the primary form of the sleeve comprising ethylene vinyl acetate.
  • the injection molded primary form of the sleeve is removed from the first mold.
  • a core bar is inserted into the inner cavity of the primary form of the sleeve.
  • the core bar and the primary form of the sleeve are inserted into additional tooling machinery to allow for control of the temperature and time spent at the one or more temperatures to control the coagulation of the ethylene vinyl acetate.
  • Embodiments of the present invention include one or more advantages including offering great feel by absorbing shock and vibrations caused by the article impacting other objects and being light in weight and of low density.
  • lighter grips allow for the manipulation of the club swing weight.
  • Current common grips weigh approximately 52 grams.
  • Embodiments of the present invention can reduce the weight of the grip by approximately 32 grams. Generally, decreasing the weight of a grip by approximately 4.5 grams will increase one unit of the club's swing weight. Thus, a 32 gram savings in grip weight can increase a club's swing weight by approximately 7 units. Increased swing weight allows a golfer to hit the ball further with a similar stroke.
  • decreasing the weight of a grip will decrease the total weight of a club, a feature that can be beneficial to older golfers and golfers having less strength. In particular, it enables golfers to create higher head speed and provides easier maneuverability. Furthermore, light weight grips are important for longer shafted clubs which may be preferred by longer distance and taller golfers.
  • a golfer generally carries approximately 14 clubs in their bag. When that golfer is walking the course or carrying the bag any appreciable distance, it is advantageous to reduce the weight of the bag as much as possible. This can be accomplished by using embodiments of the present grip that are much lighter than standard grips.

  • a finished grip G including a polyurethane/felt gripping member 50 adhered to an EVA sleeve 2 weighs between approximately 15 and 25 grams. In a preferred embodiment, the finished grip G weighs approximately 20 grams while still providing the desired shock absorption, tackiness and torsion resistance required of a grip for an article such as a golf club.
  • FIG. 11B is an alternative view of the portion shown in FIG. 11A according to some embodiments.
  • an additional woven fabric mesh 82 is included in the polyurethane layer 58 during the manufacturing process.
  • the fabric mesh 82 is attached to the non-woven fabric layer 60 prior to depositing the polyurethane onto the fabric layer 60.
  • Such a process is known in the art. See, for example, U.S. Patent No. 6,695,713 .
  • the fabric mesh 82 includes longitudinally extending fibers (fibers that extend generally along the length of the long axis of a grip for a grip formed by a panel ( FIG. 12 ) or along the long axis of a strip where the finished grip is formed from a spirally wrapped strip) and transversely extending fibers.
  • the longitudinally extending fibers will preferably be of a larger diameter than the transversely extending fibers.
  • the longitudinal fibers may have a diameter between approximately 0.4 and 0.75 millimeters and the transverse fibers may have a diameter between approximately 0.25 and 0.5 millimeters.
  • the longitudinal and transverse fibers may be of substantially equal diameters.
  • the woven fabric mesh may be fabricated of suitable materials such as nylon, cotton, polyester, or the like.
  • FIGS. 12-15A show the application of a gripping member 50 or panel onto a sleeve 2 according to some embodiments.
  • An adhesive 162 is sprayed onto the mounting surface 12 of the sleeve 2, the inner surface 66 of the gripping member 50 or both as shown and the panel P is wrapped around the mounting surface 12.
  • the side edges 54, 56 of the panel P can be skived so as to overlap along the seam 52 with like layers generally contacting and adhered to like layers as shown in FIGS. 14 and 15 .
  • the side edges 54, 56 can be skived such that the outer surface 64 of the panel P at or near the side edges 54, 56 contact each other along the seam 52.
  • such a seam 52 is stitched closed with the stitches 170 preferably extending through at least a portion of the polyurethane outer layer 58 and at least a portion of the felt inner layer 60 as shown in FIG. 15A .
  • the panel P is stitched inside out with the polyurethane surface 64 facing inwards and, after stitching the seam 52, the panel P is reversed as it is applied to the sleeve 2 such that, on the finished grip G, the polyurethane surface 64 is outward facing.
  • the thickness 180 ( FIG. 11A ) of the panel P corresponds generally to the distance 190 the nipple contact surface 18 ( FIG. 2 ) extends from the mounting surface 12 to facilitate the creation of a smooth transition from the gripping member 50 to the nipple 14. In some embodiments, the thickness 180 of the panel P corresponds generally to the distance 192 the cap contact surface 28 extends from the mounting surface 12 to facilitate the creation of a smooth transition from the gripping member 50 to the cap 22.
  • the EVA sleeve 2 is injection molded rather than ground down from a block 32 of EVA foam.
  • Ethylene vinyl acetate copolymers possess many excellent characteristics such as low weight, low density, flexibility, transparency, non-toxicity and good resistance to environmental stress cracking, etc.
  • Some embodiments of the present invention overcome the difficulties of working with injection molded EVA. For example, EVA coagulation is a relatively slow process. After injection molding a rough EVA sleeve, a core bar can be inserted inside the sleeve and the sleeve can be transferred to an appropriate mold to control the shape of the finished product. Controlling temperature and time facilitates effective control of the EVA coagulation.
  • the density of the EVA injected to form the sleeve 2 is less than approximately 1 g/cm 3 . In some embodiments, the density is between approximately 0.9 and 1 g/cm 3 . In a preferred embodiment, the density is between approximately 0.930 and 0.943 g/cm 3 . Controlling the degree of coagulation of the EVA allows embodiments of the invention to include an EVA sleeve 2 whose volume is, for example, approximately doubled or tripled from the original volume. Therefore, in some embodiments, the density of the finished sleeve 2 can be approximately one half or one third of the original density.
  • the density of the finished sleeve 2 can be between approximately 0.25 and 0.75 g/cm 3 . In some embodiments, the density of the finished sleeve 2 can be between approximately 0.3 and 0.6 g/cm 3 . In some embodiments, the weight of the finished sleeve 2 can be between approximately 5 and 15 g. In some embodiments, the weight of the finished sleeve 2 can be between approximately 7 and 12 g. In a preferred embodiment, the finished sleeve 2 weighs approximately 10 g.
