Abstract

A collapsible and adjustable golf club characterized by the presence of a selector means that includes first and second interlocking systems having different spaces between their respective points of mechanical interlock whereby uniform increments of adjustment may be made to vary the loft of the club to a preselected angle and with the shaft of the club being collapsible for storage purposes.

Claims

1. An adjustable golf club of the character described, comprising;

A. an angular shaped shank member receiviNg a golf shaft at one end thereof and having 1. an angular boss and a shaft projecting therefrom at the other end thereof, with said shaft having a threaded reduced diameter projecting end 2. a first series of lugs provided about the entire periphery on one face of said boss about the axis of said shaft;

B. a club head member having 1. a ball engaging surface, a rear face, a heel portion, and a toe portion;

2. a through bore located rearwardly of said ball engaging surface and interconnecting said heel and toe portion of said club head and receiving said shaft therein whereby the angle of inclination of said ball engaging surface may be varied by rotating said club head around said shaft;

3. a counterbore concentric with respect to said bore and opening into said rear face at said heel portion thereof; and

4. a second series of lugs arranged around the axis of said bore on one face of said counterbore;

C. a selector ring 1. rotatably received in said counterbore and having a through bore received over said shaft in concentricity therewith; and

2. having third and fourth series of lugs provided on the opposed faces thereof around the axis of said ring, with said first series of lugs on said boss being identical in number to and meshing with said third series of lugs of said selector ring while said second series of lugs on said counterbore is identical in number to and meshes with said fourth series of lug members on said selector ring, said first, second, third, and fourth series of lugs being concentric with respect to each other and the axis of said bore;

D. means for permitting said first, second, third and fourth series of lug members to move into and out of meshed condition with each other whereby the loft angle of said club head member can be adjusted by rotation of said club head relatively of said shank member and said selector ring; and

E. indicia means provided on said base, said selector ring, and said rear face of said club adjacent said counterbore whereby the loft angle of said club can be determined.

2. said components are frictionally locked against relative rotation about their common axis of rotation when positioned in said extended position.

3. a counterbore concentric with respect to said bore and opening into said rear face at said heel portion thereof;

and

4. The adjustable golf club of claim 3 further characterized by the fact that at least one of said stepped shaft portions has a roughened surface that engages its complemental counterpart when said components are moved to said extended position.
