Benefits of technology

The invention is an interchangeable golf club grip assembly that can be easily attached and removed from a golf club shaft. The assembly includes a sleeve that fits over the shaft, an upper mechanism for securely attaching the sleeve to the shaft, and a grip portion that provides a comfortable grip for the golfer. The grip portion can be designed to accommodate different shaft diameters and has a threaded fastener or a separate clamp to securely hold the assembly in place. The invention also allows for adjusting the loft and lie angles of the golf club by angling the grip portion. Overall, the invention provides a convenient and customizable solution for golfers to modify the feel and performance of their golf clubs.

Problems solved by technology

However, grips for putters have not previously been provided which can be positioned on a shaft in such a way as to modify the loft and lie angles of the putter.
Because conventional golf club grips, or a sleeve component thereof, are adhesively attached to the shaft, it is not possible to change a grip without first cutting it off the shaft.
Consequently, the removal of conventional golf club grips from the shaft requires their destruction.
Furthermore, it is a laborious process to cut an adhesively secured grip or grip sleeve from a shaft and to remove the adhesive residue so that another grip may be attached.

first embodiment

[0124]FIGS. 35A and 35B illustrate a grip portion that is comprised of two materials of different densities, each of which comprises a different part of the grip portion. As shown therein, grip portion 1074 comprises a first material of a first density D1 that occupies radial portion 1076 comprising 180° of the circumference of the grip portion and a second material of a second density D2 that is different from the first density D1 that occupies radial portion 1078 also comprising 180° of the circumference of the grip portion. In other embodiments of the invention, the materials of different densities may occupy differently sized radial portions of the grip assembly. Preferably, however, a first material having a density of D1 occupies a radial portion R1 comprising at least about 90° of the circumference of the grip portion, and a second material having a density D2 that is different from density D1 occupies a radial portion R2 comprising 360°-R1 of the circumference of the grip po...

second embodiment

[0125]FIGS. 36A and 36B illustrate a grip portion that is comprised of two materials of different densities. As shown therein, grip portion 1080 comprises a first material of a first density D1 that occupies a portion 1082 of the grip portion that extends for a length L1 in a direction that is parallel to the axis of the grip portion, and a second material of a second density D2 that is different from the first density D1 that occupies the remainder 1084 of the space occupied by the grip portion. In this embodiment of the invention, the outer surface of portion 1082 occupies about 50° of the circumference of grip portion 1080, and the distance L1 comprises about 18% of the total length of grip portion 1080. In other embodiments of the invention, the materials of different densities may occupy differently sized radial portions and / or portions of different lengths of the grip assembly. In other embodiments of the invention, three or more materials, each having a different density, may...

Abstract

A grip assembly for a golf club is adapted to be removably attached to the upper portion of a golf club shaft. This grip assembly includes a sleeve that is adapted to fit over the upper portion of the shaft and a grip portion that is adapted to provide a gripping surface for a golfer. The assembly also includes an upper mechanism for removably securing the top end of the sleeve to the golf club shaft and a lower mechanism for removably securing the bottom end of the sleeve to the golf club shaft by applying a radially-directed compression force to the sleeve on the shaft.
