Abstract

An Adjustable Golf Club including a series of golf club styles in a singular unit comprising a shaft member, a club head attachment member affixed to and orthogonal to the shaft member, a club head member pivoting about an axis orthogonally disposed to the shaft member, and a locking mechanism to establish the club head member at a fixed angular disposition relative to the pivotal axis of rotation.

Claims

1. A new and improved adjustable golf club for incorporating a series of golf club styles in a singular unit comprising:

a shaft member having a longitudinal axis,

a club head attachment member affixed to said shaft member, said club head attachment member being disposed within a first plane orthogonally oriented relative to a second plane containing said longitudinal axis of said shaft member,

a club head member pivoting about an axis orthogonally disposed relative to said second plane containing said longitudinal axis of said shaft member, and

a locking means to establish the club head member at a fixed angular disposition relative to the pivotal axis of rotation, said locking means comprising a plurality of spring energized cylindrical pins engaging holes in the club head attachment member, said holes in the club head attachment member comprising through-extending holes on a cylindrical member arranged as a nine element array having a plurality of array columns and array rows.

2. The new and improved adjustable golf club of claim 1 in which said array rows are displaced from one another by an amount equal to one half the distance between centers of any two holes in any of the array columns.

3. The new and improved adjustable golf club of claim 1, and further comprising a plurality of tension members each coupled to an individual one of said cylindrical pins, wherein said locking means is disengaged by an application of an external force to said tension members and further wherein said tension members transmit force from a single external activation source.
