Abstract
A golf club grip includes a molded or shaped tubular foam body of closed-cell foam material and an anti-slip rubbery skin bonded integrally to an outer surface of the tubular foam body, thus a slip-on type of this invention is formed. The closed-call foam provides advantages, such as light weight with correct or standard size, a wide range of size and grip weights for personal choice. The tubular foam body has a capped end to cap a grip-mounting portion of a golf club shaft. In an embodiment of coiled strip type, the tubular foam body is cut spirally to form a coiled strip that can be wrapped spirally around the grip-mounting portion, and the capped end is formed as a cap which is integral with the coiled strip.
Claims21
A golf club comprising:
- a shaft having a grip mounting portion;
- and
- a grip which includes:
- a tubular foam body mounted on said grip mounting portion and formed from a closed-cell foam material, said foam body including an integrated capped end, an open end opposite to said capped end, and an outer surface extending between said capped end and said open end, and
- an anti-slip rubbery skin extending around and covering at least a portion of said outer surface of said tubular foam body,
- wherein said closed-cell foam has a hardness in the range of 40˜70 in ASTM D2240 Type C hardness scale.
A golf club comprising:
- a shaft having a grip mounting portion;
- and
- a grip which includes:
- a tubular foam body mounted on said grip mounting portion and formed from a closed-cell foam material, said foam body including an integrated capped end, an open end opposite to said capped end, and an outer surface extending between said capped end and said open end, and
- an anti-slip rubbery skin extending around and covering at least a portion of said outer surface of said tubular foam body,
- wherein said closed-cell foam has a density in the range of 0.12˜0.3 g/cm3.
A golf club comprising:
- a shaft having a grip mounting portion;
- and
- a grip which includes:
- a tubular foam body mounted on said grip mounting portion and formed from a closed-cell foam material, said foam body including an integrated capped end, an open end opposite to said capped end, and an outer surface extending between said capped end and said open end, and
- an anti-slip rubbery skin extending around and covering at least a portion of said outer surface of said tubular foam body,
- wherein said tubular foam body of said grip includes:
- a coiled strip extending spirally and wrapped about said grip mounting portion of said shaft;
- and
- a cap capping one end of said grip mounting portion and formed as one piece with said coil strip, said cap having a rim extending around the grip mounting portion, said rim being connected integrally to one end of said coiled strip, and
- wherein said grip further includes a stretchable reinforcing member to be positioned over said rim and said coiled strip where said rim is connected to said coiled strip.
A golf club comprising:
- a shaft having a grip mounting portion;
- and
- a grip which includes:
- a tubular foam body mounted on said grip mounting portion and formed from a closed-cell foam material, said foam body including an integrated capped end, an open end opposite to said capped end, and an outer surface extending between said capped end and said open end, and
- an anti-slip rubbery skin extending around and covering at least a portion of said outer surface of said tubular foam body,
- wherein said tubular foam body of said grip includes:
- a coiled strip extending spirally and wrapped about said grip mounting portion of said shaft;
- and
- a cap capping one end of said grip mounting portion and formed as one piece with said coil strip, said cap having a rim extending around the grip mounting portion, said rim being connected integrally to one end of said coiled strip, and
- wherein said coiled strip has a cap connecting end connected to said rim, and a tip end opposite to said cap connecting end, said coiled strip further having a thickness which decreases from said cap connecting end to said tip end, and
- wherein said coiled strip has a variance of about 3 mm between the thickness of said cap connecting end and the thickness of said tip end.
