Adjustable bicycle handle bar adapter and associated method
First Claim
1. A bicycle headstock assembly for adjusting a height and a reach of a handle bar of a bicycle, said bicycle headstock assembly comprising:
- a lower member adapted to be attached to a steering rod of the bicycle;
an upper member connected to said lower member;
a pivot joint formed at a connection of said lower and upper members;
a handle bar clamp connected to said upper member;
a primary fastener passed through a first location of said pivot joint; and
an auxiliary fastener passed through a second location of said pivot joint;
wherein said primary and auxiliary fasteners cooperate to permit said upper member to selectively pivot and lock at alternate positions relative to said lower member;
wherein said pivot joint comprises;
a plurality of first annular plates statically attached to a proximal end of said upper member, said first annular plates being spaced apart at a fixed spatial distance; and
a plurality of second annular plates statically attached to an upper end of said lower member, said second annular plates being spaced apart at a fixed spatial distance respectively;
wherein said first annular plates are rotatably interfitted between said second annular plates respectively such that said first and second annular plates are juxtaposed side-by-side in a parallel configuration;
wherein said first and second annular plates are co-axially aligned along a fulcrum axis of said pivot joint.

Abstract
A bicycle headstock assembly may include a lower member adapted to be attached to a steering rod of the bicycle, and an upper member adjustably connected to the lower member. A pivot joint may be formed at a connection of the lower and upper members respectively. A handle bar clamp may be connected to the upper member and extending away therefrom. A primary fastener may pass through a first location of the pivot joint while an auxiliary fastener may pass through a second location of the pivot joint respectively. In this way, the primary and auxiliary fasteners may cooperate to permit the upper member to selectively pivot and lock at alternate positions relative to the lower member.
