Description
- The present application claims priority under 35 U.S.C. §119(e)(1) to provisional application No. 60/987,790 filed on Nov. 14, 2007, the contents of which are incorporated herein by reference.
- 1. Technical Field
- The present invention relates to golf club grips in general, and in particular to a vibration reduction golf club grip.
- 2. Description of Related Art
- When hitting a golf ball with a golf club, a golfer usually feels some vibrations generated from a golf club. Much of the vibrations are high-frequency vibrations arise from the face of the golf club head impacting a golf ball improperly or striking the ground. In addition, when a golf ball is struck at any location away from the preferred striking area (commonly known as “sweet spot”) of the golf club or when a golf ball is struck at a wrong angle of attack relative to the face of the golf club head, a considerable amount of torsional vibration can also be induced.
- Golf club vibration, at a minimum, is an annoyance that interferes with a golfer's enjoyment of a golf game. But often, a chronic soreness can be induced in a golfer's hand, wrist or elbow from long exposure to golf club vibration. One such condition is known as medial epicondylitis in medical term, and it is often exacerbated by a golfer's age and the frequency of play.
- Over the years, various schemes have been conceived by the golf club industry to reduce the golf club vibration felt by golfers at large. Those schemes include placing counter vibration weights and rods inside golf club shafts, filling shafts with vibration damping structures, placing coupling joints along the length of a shaft, altering the shape of a club head, etc. The problem with those schemes in that, in many cases, the alterations can add masses to a golf club and/or sacrifice structural integrity of the golf club. Furthermore, many of those schemes are ineffective against high-frequency vibration and/or making a golf club feel “mushy” or “sluggish.” Although high-frequency vibration of a golf club can lead to discomfort and joint damage, low-frequency vibration of a golf club is associated with a feeling of quality shot. Because sometimes the alterations may reduce all frequencies of golf club vibration, a golfer may lose the feel of a good shot.
- Consequently, it would be desirable to provide a golf club grip for reducing the high-frequency vibration that can lead to tissue damage while retaining low-frequency vibration that is associated with quality shots.
- In accordance with a preferred embodiment of the present invention, a golf club grip 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. In addition, 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.
- All features and advantages of the present invention will become apparent in the following detailed written description.
- The invention itself, as well as a preferred mode of use, further objects, and advantages thereof, will best be understood by reference to the following detailed description of an illustrative embodiment when read in conjunction with the accompanying drawings, wherein:
-
FIGS. 1A and 1B 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; and -
FIGS. 3A and 3B are diagrams of a golf club grip, in accordance with an alternative embodiment of the present invention. - Referring now to the drawings and in particular to
FIGS. 1A-1B , there are depicted diagrams of a golf club grip, according to the prior art.FIG. 1A is a side view of agolf club grip 10, andFIG. 1B is a cross-sectional view ofgolf club grip 10 along A-A. Any vibration generated in ashaft 11 is transferred to the hands of a golfer viagolf 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 withgolf club grip 10 may lead to problems from soreness to chronic pain in elbows and joints. - With reference now to
FIGS. 2A-2B , there are depicted diagrams of a golf club grip, in accordance with a preferred embodiment of the present invention.FIG. 2A is a side view of agolf club grip 20, andFIG. 2B is a cross-sectional view ofgolf club grip 20 along B-B. As shown,golf club grip 20 includes alongitudinal cavity 25 adapted to receive ashaft 21. Withingolf club grip 20 and distributed aboutcavity 25 is acircular cavity 22.Cavity 22 is a circular elongated cavity extending longitudinally parallel tocavity 25.Cavity 22 can be tapered as it extends longitudinally alongcavity 25. Preferably,cavity 22 is filled with acompressible material 29. When subjected to torsional vibrations,compressional material 29 deforms and compresses into and aroundcavity 22. -
Material 29 may take various forms including Santoprene™, thermoplastics, elastomers, composites, and rubbers, etc.Cavity 22 andmaterial 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 ofcavity 22 as well as the durometer ofmaterial 29. - In addition,
cavity 22 compress slightly whengolf club grip 20 is grasped by a golfer. As a result, golf club grip 20 conforms to the golf's hand, enabling a more secure, stronger grip without excess exertion by the golfer.Cavity 22 also reduces the weight ofgolf 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 toshaft 21. Alternately, they may spiral longitudinally or form other patterns. In addition,cavity 22 may be opened to or sealed from the environment. - Referring now to
FIGS. 3A-3B , there are depicted diagrams of a golf club grip, in accordance with an alternative embodiment of the present invention.FIG. 3A is a side view of agolf club grip 30, andFIG. 3B is a cross-sectional view ofgolf club grip 30 along C-C. As shown,golf club grip 30 includes alongitudinal cavity 35 having a first section 36 and asecond section 37. First section 36 has an even diameter adapted to receive ashaft 31.Second section 37 has a tapered shape preferably filled with acompressible material 39. When subjected to torsional vibrations,compressional material 39 deforms and compresses intosecond section 37 ofcavity 35. One opening ofsecond section 37 ofcavity 35 can be closed by using an end cap (not shown). - As has been described, 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.
- While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
