Abstract
An adjustable golf shaft for a golf club which allows a child to use the same set of golf clubs during childhood and into his or her teen years. The golf shaft has a first shaft member, a second shaft member telescopically positioned within the first shaft member, and a compression fitting which fixedly attaches the first shaft member to the second shaft member at a desired golf shaft length. As the child grows, the compression fitting can be loosened, the second shaft member can be expanded outward from the first shaft member lengthening the golf shaft, and the compression fitting can be tightened fixing the first shaft member relative to the second shaft member.

A golf shaft for a golf club having a head and a grip, the golf shaft comprising:
- (a) a first shaft member having a first end, a second end, an inner diameter and an outer diameter;
- (b) a second shaft member having a first end, a second end, and an outer diameter, the second shaft member telescopically positioned within the first shaft member, the second shaft member outer diameter at the second end being larger than the first shaft member inner diameter at the first end whereby the second shaft member can not be separated from the first shaft member by extracting the second shaft member second end through the first shaft member first end;
- and
- (c) means for compressing the first shaft member first end around the second shaft member to fixedly attach the first shaft member to the second shaft member at one of a plurality of locations along the length of the second shaft member such that when the head of the golf club impacts a golf ball the first shaft member and the second shaft member will remain in a fixed longitudinal relationship with respect to each other wherein the compression means comprises
- a bolt having a head and a hollow cylindrical rod extending from the head, the cylindrical rod having external threads and at least one longitudinal slit allowing the inner diameter of the rod to decrease to a diameter smaller than the outer diameter of the first shaft member first end, the bolt slidably positioned on the first shaft member;
- a nut having internal threads that mate with the external threads of the bolt and slidably positioned on the golf shaft;
- and
- a compression ring positioned between the golf shaft and the nut.
