Definitions

  • the present invention relates to an improved grip for golf clubs.
  • Description of Prior Art [0002] Applicant has previously developed resilient grips which successfully reduce impact shock to the muscle and arm joints of the user's of golf clubs and also provide a feeling of tackiness between a player's hands and the grip. See for example U.S. Patent No. 5,797,813 granted to Applicant on August 25, 1998.
  • Such earlier grips utilize a polyurethane-felt strip which is spirally wrapped around an underlisting sleeve that is slipped onto and adhered to a golf club handle. The sides of the strips are formed with overlapping heat depressed recessed reinforcement edges.
  • the grip will tend to absorb the perspiration from the user's hand and may become saturated during play thereby causing slippage of the golf club or tennis racquet in the user's hands.
  • EVA ethylene-vinyl acetate copolymer
  • the golf club grip overcomes the aforementioned disadvantages of existing spirally wrapped grips while providing the same resistance to shock afforded by such grips, as well as providing tackiness, reducing the overall weight of the grip and providing a resistance to absorbing water which can impair the above-mentioned advantages.
  • the disadvantages are eliminated by forming a structurally integral grip from a single polyurethane- EVA panel having a configuration corresponding to the exterior shape of an underlisting sleeve. The side edges of such single panel abut one another and, preferably, are adhered together to define a longitudinal seam extending through the panel.
  • a heat formed recessed sealing channel may be formed in the exterior portion of the polyurethane layer at the outer end of the seam to strengthen such seam.
  • Hot polyurethane is deposited along the seam or within the channel, and after such polyurethane has hardened it is buffed to smoothly blend into the surface of the grip.
  • a mold is utilized to emboss a friction enhancing pattern over the deposited polyurethane to match the friction enhancing pattern of the main body of the surface of the grip.
  • Another embodiment is a grip for the handle of a golf club including an underlisting sleeve and a single panel. The underlisting sleeve is telescopically slipped onto the handle of a golf club.
  • the single panel includes a polymeric outside layer bonded to a polymeric inside layer.
  • the panel is wrapped about and adhered to the underlisting sleeve with the side edges of the panel abutting one another to define a longitudinal seam extending from the interior surface of the inside layer to the exterior surface of the outside layer.
  • the side edges are adhered together.
  • a polymeric material is deposited along the seam.
  • a heat depressed channel is formed exteriorially of the seam.
  • the channel is filled with a polymeric deposit, h yet another embodiment, the polymeric deposits are smooth buffed.
  • a segment of friction enhancing pattern is formed outwardly of the seam so as to merge the friction enhancing pattern formed on the outside of the outside layer.
  • Another embodiment is a method of making a grip for the handle of a golf club including the following steps: providing an underlisting sleeve that is telescopically slipped onto the handle of a golf club, providing a single panel that includes a polyurethane outside layer bonded to an EVA inside layer, wherein the panel has a configuration corresponding to the exterior shape of the resilient sleeve, wrapping the single panel about and adhering it to the underlisting sleeve and abutting the side edges of the panel together to define a longitudinal seam extending from the interior surface of the inside layer to the exterior surface of the outside layer.
  • the golf club grip may be manufactured at considerably less cost than existing spirally wrapped grips, since the intensive labor of spirally wrapping a strip around an underlisting sleeve within specific pressure parameters is eliminated. Additionally, the single panel grip will desirably not twist either during nianufacture or after it is adhered to an underlisting sleeve.
  • My new grip desirably has an appearance similar to conventional molded rubber grips so as to appeal to professional golfers and low-handicap amateurs, and desirably also provides a greater area for the application of decorative designs. Further, the EVA inside layer of my new grip will resist the absorption of water to preserve the other advantages provided by the grip when the grip is exposed to moisture.

Alternatively, channel 95 is not buffed after it is filled with hot polyurethane 96. [0099] Referring now to FIGS.
  • Grip G-4 does not use the channel 95. Rather, seam 91 is coated by a small deposite of hot polyurethane 96 by means of a nozzle, brush or the like, as shown in FIG. 50. After the polyurethane 96 hardens, it may be buffed by a suitable brush or the like 97 to smoothly blend into the surface of the grip, as indicated in FIG. 51. Alternatively, the polyurethane 96 is not buffed. [0100] In still another embodiment, the adhesive 90 is sprayed on the EVA layer 62 such that it covers only the EVA layer 62 and does not extend to cover the edges of the polyurethane layer 60.
  • hot polyurethane 96 may be injected between the polyurethane layers of the seam 91 by a needle, brush, sprayer or the like. After the polyurethane 96 hardens, it may be buffed by a suitable brush or the like 97 to smoothly blend in the surface of the grip any polyurethane 96 spilling from the seam. Alternatively, the polyurethane is not buffed. [0101] Referring to FIGS. 53-63, there is shown a modification of the grips of FIGS. 32- 52. In FIGS. 53-55, hot polyurethane 96 is shown being coated over the seam 91 by a nozzle, brush or the like. In FIGS.
  • hot polyurethane 96 is shown filling the depression 95 by a nozzle, brush or the like. In another embodiment, hot polyurethane 96 is injected between the edges of the polyurethane layer along the seam.
  • FIG. 59 shows a third mold M3 having a heated platen 100, the underside of which is formed with a segment 63 a of the friction enhancing pattern 63, which is embossed on the surface of the polyurethane layer 60 of the grip. The heated platen 100 is depressed against the outside surface of the polyurethane layer 60 over the area of the seam 91 while the polyurethane deposit 96 is still hot.
  • the area of the exterior of the polyurethane layer 60 outwardly of the seam 91 is formed with the friction enhancing segment 63 a of FIG. 60 whereby the segment 63 a merges with the friction enhancing pattern 63 previously molded on the polyurethane layer 60 of the grip G.
  • FIG. 63 shows such a grip G-5 with the merged friction enhancing pattern 63 placed over and adhered to the shaft 55 of a golf club GC.
  • the heated platen 100 may be urged against the naked seam 91 to form the friction enhancing pattern without first coating in or along the seam 91 with hot polyurethane 96.
  • FIGS. 64-73 there is shown a polyurethane-EVA single panel grip PG for use with a conventional putter P.
  • the grip PG includes a resilient underlisting UP (FIGS. 64-68), which is generally similar to the aforedescribed underlisting U, except that underlisting sleeve UP is not of an annular configuration. Instead, the front surface 98 of underlisting sleeve UP is of flat configuration in accordance with the design of most putters in general use.
  • underlisting sleeve UP receives a single panel SP of polyurethane-EVA configuration, similar to the aforedescribed single panel S.
  • Such single panel SP is wrapped about and adhered to the underlisting sleeve in the same manner as described hereinbefore with respect to the panel P in the polyurethane-EVA single panel grips G-l - G-5, with like parts of the two grips marked with like reference numerals.
  • a tooth 94' is used to create a channel 95', that channel 95' may be left alone or filled with hot polyurethane 96' and left alone or buffed with a brush or the like 97' (refer to FIGS.
  • the panel SP is smooth as shown in FIG. 69. Because a putter P is generally subjected to less forces due to the shortened putting swing as compared to the generally longer swing associated with other clubs, it is contemplated that putter grip PG does not require the friction enhancing pattern 63'.
  • the panel SP may incorporate a smaller heat embossed visual indicial such as logo 114' (not shown), a heat embossed friction enhancing pattern 63' (not shown), an inked visual indicia 118' (not shown), a larger heat embossed pattern extending the majority of the length of the panel 118' (not shown) or any combination or modification thereof.
  • a grip embodying the present invention may be coated by means of a brush, nozzle, sprayer or the like with a thin layer of polymeric material, preferably polyurethane (not shown), to protect such surface, add tackiness thereto and increase the durability thereof.
  • Golf club grips of the present invention provide several advantages over existing wrapped grips and single panel grips. Additionally, such grips have the appearance of molded, one-piece grips familiar to professional and low-handicap golfers. Although some of such golfers are reluctant to use a non-traditional wrapped club, they are willing to play with a structurally integral grip of the present invention since such grip affords the shock-absorbing and tackiness qualities of a wrapped grip.
