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 golf club having a detachable head, comprising:
- a first shaft segment and a second shaft segment, the first shaft segment having a grip or handle attached thereto and the second shaft segment being fixedly attached to a golf club head, wherein one of the first shaft and the second shaft has an insertion pin having a conical insertion section, the conical insertion section having a top and a base, the base having a radius greater than a radius of the top such that the length of the conical insertion section from the base to the top is greater than the radius of the base of the conical insertion section, and the other of the first shaft and the second shaft has a receptor pin having a conical receptor section;
- and
- a coupler affixed to either the first shaft segment or the second shaft segment for reversibly mating the handle to the club head, wherein the coupler comprises a pull-back sleeve movable with respect to the conical receptor section to allow for movement of one or more first ball bearings within the coupler such that in a first pull-back sleeve position, the ball bearings allow insertion of an insertion pin during mating of the first and second shaft segments, and in a second pull-back sleeve position, the ball bearings exert a force on the conical insertion section to tightly couple the first shaft segment to the second shaft segment.
A golf club, comprising:
- a first shaft segment, coupled to a handle end of the golf club, the first shaft segment having a fixed length;
- and a second shaft segment coupled to a club head end of the golf club, the second shaft having a length dependent on a type of club head to which it is attached.
