Abstract

A system of interchangeable club heads sharing one or more shafts and golf bag for carrying the club heads and one or more shafts. The club heads contain a shaft segment to set club length and a coupler to interconnect to the shaft and grip. The shaft contains an opposite gender coupler. The system is very lightweight and much more portable than a conventional set of golf clubs. It also creates the opportunity for players to match club heads with shafts with differing performance characteristics. Additionally, it solves a problem for golfers using long shafts on putters. These long shafts can now be disassembled for storage and transport. A ramp on the circumference of one end of a pullback sleeve works in conjunction with a post on a grip end fitting to more tightly couple the club head end to a shaft.

Dependent claims

A golf club system, comprising:

an upper shaft segment having a golf club grip thereon and a first portion of a first coupler;
a lower shaft segment having a second portion of the first coupler to be mated with the first portion of the first coupler, the lower shaft segment further having a grip end fitting that forms a first portion of a second coupler, wherein the grip end fitting that forms the first portion of the second coupler includes a pullback sleeve with two ends and a post, the pullback sleeve having a ramp on one end extending a portion of the way around the circumference of the pullback sleeve;
and
a plurality of golf club heads, each golf club head having a club head fitting that forms a second portion of the second coupler to be mated with the grip end fitting;
wherein when the pullback sleeve is twisted in one direction, the post rides up the ramp until it becomes too difficult for twisting to continue such that the golf club head is securely fastened to the lower shaft segment.
