Description
    CROSS-REFERENCE TO RELATED APPLICATION
  • [0001]
    This application claims priority of Taiwanese Application No. 094101660, filed on Jan. 20, 2005.
  • BACKGROUND OF THE INVENTION
  • [0002]
    1. Field of the Invention
  • [0003]
    The invention relates to a golf club grip, more particularly to a golf club grip which has a cap that is easy to assemble and which has a flexible design to meet various specific demands.
  • [0004]
    2. Description of the Related Art
  • [0005]
    U.S. Pat. No. 2,721,741 discloses a grip piece for a golf club shaft. The grip piece includes a hollow cap portion and a strip portion integrated with the cap portion. The cap portion is adapted to fit over an end of the shaft on which the grip piece is attached. Inside an end of the cap is a key, which fits into a corresponding slot in the end of the shaft. The grip piece is assembled by wrapping the strip portion around the shaft and fastening its free end to the shaft with wrapping or the like. The cap portion is then pulled out from the shaft end and twisted in the direction of twist in the strip portion to tighten and even the strip portion on the shaft. Finally, the cap portion is let back on the end of the shaft, taking care to force the key into the slot in the end of the shaft. In practice, however, it is relatively difficult for a golf player to force the key into the slot in the end of the shaft.
  • [0006]
    Referring to FIG. 1, U.S. Pat. No. 5,816,933 discloses a golf club shaft grip which includes an elongated resilient strip 11 spirally wrapped about a golf club shaft 10, and an annular cap 12 telescopically received by an upper end of the shaft 10 to restrain the strip 11 from unraveling relative to the shaft 10. The strip 11 has an open-pored felt layer adhered to the golf club shaft 10, and a smooth closed pore polyurethane layer bonded to the felt layer. The cap 12 includes an inner skirt 120 and an outer skirt 121. The cap 12 is secured to an upper open end of the shaft 10 in a manner in which the inner skirt 120 is tightly and telescopically received by the upper open end of the shaft 10 and in which the outer skirt 64 can tightly and telescopically enclose the first wrap of the strip 11. However, the cap 12 is liable to disengage from the upper open end of the shaft 10 after a period of use. Furthermore, since the strip 11 is relatively thin, the application of the grip to various sizes of golf club shafts is limited.
  • [0007]
    Referring to FIGS. 2 and 3, in Taiwanese Patent Publication No. 559,098, there is disclosed a golf club grip 2 including an inner tubular body 20, an anti-slip skin 21, and a rigid cap 22. The tubular body 20 includes a first end portion 202, a second end portion 201 opposite to the first end portion 202, and a tubular wall surface 200 extending between the first and second end portions 202, 201. The first end portion 202 has a cross section larger than that of the tubular wall surface 200, and is formed with a vent hole 2030 in a top face thereof and a projection 203 around the event hole 2030. The second end portion 201 is formed as a ring. The anti-slip skin 21 is a tailored sheet, and extends around and covers the tubular wall surface 200 of the tubular body 20 between the first and second end portions 202, 201 of the tubular body 20. The anti-slip skin 21 has a first end portion 211 abutting against the second end portion 201 of the tubular body 20, and a second end portion 212 proximate to the first end portion 202 of the tubular body 20. A gap 222 is formed between the second end portion 212 of the anti-slip skin 21 and the first end portion 202 of the tubular body 20. The cap 22 includes a cover plate 223 having a fastening hold 220, and a skirt portion 221 extending peripherally and axially from the cover plate 223 in a direction toward the second end portion 201 of the tubular body 20. The cap 22 can be fastened to the first end portion 202 of the tubular body 20 by engaging the fastening hole 220 to the projection 203 of the first end portion 202 of the tubular body 20.
  • [0008]
    While production efficiency of the golf club grip 2 is increased, the fastening hole 220 of the cap 22 is required for fastening the cap 22 to the first end portion 202 of the tubular body 20. Since the cover plate 223 of the cap 22 is not formed with a continuously smooth top face, the integral appearance of the cover plate 223 of the cap 22 is destroyed, and the flexibility in the selection of materials and in the design of the golf club grip is limited.

  • [0034]
    The single-sheet anti-slip skin 6 extends around and covers the tubular wall surface 54 of the tubular body 5 between the first and second end portions 52, 51 of the tubular body 5, and has a first end portion 60 abutting against the ring 511, and a second end portion 61 abutting against the skirt portion 701. In this embodiment, the skirt portion 701 of the cap body 70 overlaps the second end portion 61 of the anti-slip skin 6. In particular, the skirt portion 701 of the cap body 70 has an inner surface 7011 abutting against the second end portion 61 of the anti-slip skin 6. Preferably, the anti-slip skin 6 is a tailored sheet made of natural leather, synthetic leather, cloth, other fibrillous material, or the like. Preferably, the anti-slip skin 6 is adhered to the tubular wall surface 54 of the tubular body 5 using a suitable binding layer 30, such as a resin layer.
  • [0035]
    Referring to FIG. 6, two edges portions 62, 63 of the anti-slip skin 6 abut against each other along an axial direction of the tubular body 5. Referring to FIG. 7, alternatively, the edge portions 62, 63 of the anti-slip skin 6 can be formed respectively with short butt sections 620, 630 that overlap each other along a transverse direction transverse to the axial direction. The total thickness of the butt sections 620, 630 should be equal to the thickness of the anti-slip skin 6 so as to result in a neat joint for the butt sections 620, 630 along the axial direction of the tubular body 5.
  • [0036]
    Since the skirt portion 701 of the cap body 700 overlaps the second end portion 61 of the anti-slip skin 6, the outer appearance of the golf club grip 3 will not be affected even though a clearance is formed between the second end portion 61 of the anti-slip skin 6 and the first end portion 52 of the tubular body 6 due to a manufacturing tolerance of the tubular body 5. Furthermore, due to the absence of the projection 203 around the vent hole 2030, which is required in the prior art of FIGS. 2 and 3 described hereinabove, the cover plate 700 of the cap 7 has a continuous top surface, which can be utilized sufficiently. Therefore, there is greater flexibility in the selection of materials and in the design of the golf club grip 3.
  • [0037]
    The golf club grip 3 of this invention can be assembled with relative ease through the following steps:
  • [0038]

  • [0040]
    3) mounting and fastening the hard shell cap 7 to the first end portion 52 of the tubular body 5.
  • [0041]
    When it is desired to remove the hard shell cap 7 from the tubular body 5, such as when replacing with a new cap, the fastening member 71 is first loosened to remove the cap body 70 such that a new cap body can be mounted and fastened afterward.
  • [0042]
    Referring to FIG. 8, the second preferred embodiment of a golf club grip 3 according to this invention is shown to be similar to the first preferred embodiment. However, in this embodiment, the hard shell cap 7 further includes a protecting lid 73 which is made of an anti-abrasive material, such as crystal glass. The peripheral flange 702 is formed with an engaging portion 7020. The protecting lid 73 engages the engaging portion 7020 of the peripheral flange 702.
  • [0043]
    Alternatively, the peripheral flange 702 of the hard shell cap 7 can be made of a material different from that of the cover plate 700 of the hard shell cap 7 so as to enhance aesthetic appeal of the hard shell cap 7. For example, the peripheral flange 702 of the hard shell cap 7 can be made of gold alloy, and the cover plate 700 of the hard shell cap 7 can be made of stainless steel.
  • [0044]
    Referring to FIGS. 9 and 10, the third preferred embodiment of a golf club grip 3 according to this invention is shown to be similar to the first preferred embodiment. However, in this embodiment, the hard shell cap 7 includes a decoration recess 705 confined by the peripheral flange 702, and a decorative member 72 (such as sapphire, emerald, or other gemstones) disposed in the decoration recess 705. Furthermore, in this preferred embodiment, the cover plate 700 of the hard shell cap 7 has a flat top surface that does not include the inserting recesses 703 and the decorative members 72 of the first and second preferred embodiments.
