Shock-absorbing bicycle handlebar assembly

A bicycle handlebar support assembly for interconnection between a handlebar and a front fork assembly, the support assembly comprising:

• (a) a head unit adapted to be secured to the front fork assembly;
• (b) an upper linkage member having a front end, and a tail end wherein said tail end is pivotally attached to said head unit;
• (c) a lower linkage member including two laterally spaced-apart longitudinally extending linkage arms located below said upper linkage member and spaced therefrom, wherein said linkage arms are pivotally attached to said head unit;
• (d) handlebar clamp assembly means for mounting the handlebar pivotally attached to said upper linkage member front end, said handlebar clamp assembly also being pivotally attached to said linkage arms;
• (e) a stop assembly including a first stop member secured to said upper linkage member adjacent said linkage arms and a second stop member secured between said linkage arms, wherein said first stop member and said second stop member are positioned so that, when said upper linkage member and said linkage arms of said lower linkage member are moved upwardly, said first stop member abuts said second stop member prior to said linkage arms contacting said upper linkage member;
• (f) a biasing member coupled between one of said linkage members and said head unit;
• and
• (g) a bearing pin having a pinhead and an eccentrically mounted pin extension projecting inwardly from said pinhead, said pinhead being movably coupled to said head unit and said pin extension being coupled to the tail end of said upper linkage member for pivotally attaching said upper linkage member to said head unit.

A bicycle handlebar support assembly for interconnection between a handlebar and a front fork assembly, the support assembly comprising:

• (a) a head unit adapted to be secured to the front fork assembly, said head unit including at least one bearing pin having a pinhead and a pin cylinder extending inwardly from said pinhead, said pin cylinder attached eccentrically to said pinhead;
• (b) a first linkage member having a front end and a tail end, wherein said tail end is pivotally attached to said head unit by being coupled to said pin cylinder;
• (c) a second linkage member having a front end and a tail end, wherein said tail end is pivotally attached to said head unit;
• and
• (d) a handlebar clamp pivotally attached to the front end of said first linkage member and pivotally attached to the front end of said second linkage member.
