Definitions

  • the present invention relates to golf club grips in general, and in particular2 to a vibration reduction golf club grip. 3 4 2. Description of Related Art 5 6
  • a golfer When hitting a golf ball with a golf club, a golfer usually feels some7 vibrations generated from a golf club. Much of the vibrations are high-frequency vibrations8 arise from the face of the golf club head impacting a golf ball improperly or striking the9 ground.
  • a golf ball is struck at any location away from the preferred0 striking area (commonly known as "sweet spot") of the golf club or when a golf ball is1 struck at a wrong angle of attack relative to the face of the golf club head, a considerable2 amount of torsional vibration can also be induced.
  • a golf club grip in accordance with a preferred embodiment of the present invention, includes a body having a substantially circular cross-sectional configuration throughout a length thereof.
  • the body includes a first end having a first diameter and a second end having a second diameter.
  • the body includes a longitudinal cavity, which is opened to the first end, adapted to receive a shaft of a golf club.
  • the body also includes a circular cavity, which is opened to the second end, distributed around the longitudinal cavity, and the circular cavity is filled with a compressible material.
  • Figures IA and IB are diagrams of a golf club grip, according to the prior art.
  • FIGS. 2A and 2B are diagrams of a golf club grip, in accordance with a preferred embodiment of the present invention.
  • Figures 3A and 3B are diagrams of a golf club grip, in accordance with an alternative embodiment of the present invention.
  • Figure IA is a side view of a golf club grip 10
  • Figure IB is a cross-sectional view of golf club grip 10 along A-A. Any vibration generated in a shaft 11 is transferred to the hands of a golfer via golf club grip 10. As such, the golfer can experience both the damaging high-frequency vibration and the torsional vibration caused by off-"sweet spot" hits. Prolong golf play with golf club grip 10 may lead to problems from soreness to chronic pain in elbows and joints.
  • FIG. 2A is a side view of a golf club grip 20
  • Figure 2B is a cross-sectional view of golf club grip 20 along B-B.
  • golf club grip 20 includes a longitudinal cavity 25 adapted to receive a shaft 21.
  • a circular cavity 22 Within golf club grip 20 and distributed about cavity 25 is a circular cavity 22.
  • Cavity 22 is a circular elongated cavity extending longitudinally parallel to cavity 25. Cavity 22 can be tapered as it extends longitudinally along cavity 25.
  • cavity 22 is filled with a compressible material 29. When subjected to torsional vibrations, compressional material 29 deforms and compresses into and around cavity 22.
  • Material 29 may take various forms including Santoprene TM , thermoplastics, elastomers, composites, and rubbers, etc.
  • Cavity 22 and material 29 act as a dampener or filter to high-frequency vibration and low- frequency vibration. However, high-frequency components of the vibration are preferentially damped more than the low-frequency components. As mentioned above, high-frequency vibration is associated with discomfort and joint pain while low- frequency vibration is associated with the feeling of the good impact and help a golf ascertain the quality of the golfer's shot. Golf club grip 20, therefore, eliminates the painful sting associated with an off-"sweet spot" shot while retaining the feel of the impact.
  • the dampening may be tuned by varying the shape and/or size of cavity 22 as well as the durometer of material 29.
  • cavity 22 compress slightly when golf club grip 20 is grasped by a golfer. As a result, golf club grip 20 conforms to the golfs hand, enabling a more secure, stronger grip without excess exertion by the golfer. Cavity 22 also reduces the weight of golf club grip 20, which enables a higher club head speed and longer drives.
  • Cavity 22 may take various forms and cross-sectional shapes. They may extend longitudinally parallel to shaft 21. Alternately, they may spiral longitudinally or form other patterns. In addition, cavity 22 may be opened to or sealed from the environment.
  • FIGs 3A-3B there are depicted diagrams of a golf club grip, in accordance with an alternative embodiment of the present invention.
  • Figure 3 A is a side view of a golf club grip 30, and
  • Figure 3B is a cross-sectional view of golf club grip 30 along C-C.
  • golf club grip 30 includes a longitudinal cavity 35 having a first section 36 and a second section 37.
  • First section 36 has an even diameter adapted to receive a shaft 31.
  • Second section 37 has a tapered shape preferably filled with a compressible material 39. When subjected to torsional vibrations, compressional material 39 deforms and compresses into second section 37 of cavity 35.
  • One opening of second section 37 of cavity 35 can be closed by using an end cap (not shown).
  • the present invention provides a golf club grip for reducing the high-frequency vibration that can lead to discomfort and tissue damage while retaining low-frequency vibration that is associated with quality shots.

Abstract

La présente invention a pour objet un grip réduisant les vibrations pour des clubs de golf. Le grip pour club de golf comprend un corps possédant une configuration sensiblement circulaire en coupe transversale sur la longueur. Le corps comprend une première extrémité ayant un premier diamètre et une seconde extrémité ayant un second diamètre. De plus, le corps comprend une cavité longitudinale qui est ouverte vers la première extrémité, adaptée pour recevoir le manche d'un club de golf. Le corps comprend également une cavité circulaire, qui est ouverte vers la seconde extrémité, répartie autour de la cavité longitudinale, et la cavité circulaire est remplie d'un matériau compressible.
