Abstract
Abstract A quick release assembly for supporting a bicycle wheel hub on a bicycle frame component. The assembly includes an elongated rod having an abutment nut threadedly disposed on one end thereof and a cam clamping assembly disposed on the other end. The clamping assembly includes a cup-shaped clamping head for rotatably supporting a cam member having an eccentric cam disposed within the cup-shaped clamping head. The eccentric cam is rotatably disposed in openings in a cylindrical reaction member. The cylindrical reaction member has a bore extending thereinto from one face to an annular flange adjacent the second face and the end of the rod has an enlarged head disposed in the bore of the reaction member and engaging the annular flange. The reaction member and the rod are separate members and the end of the rod has an arcuate recess concentric with the eccentric cam for engaging the eccentric cam to prevent rotation of the rod. The cam member has a handle extending therefrom for rotating the cam to move the clamping head relative to the reaction member between a clamping position where the rod is placed in tension and a release position for removing the bicycle wheel hub from the bicycle frame.

Claim 1
Independent Claim
292 words
A quick release assembly for supporting a bicycle wheel hub on a bicycle frame comprising: an elongated rod having first and second ends; abutment means disposed on said first end of said rod for engaging a bicycle frame; and clamping means disposed on said second end of said rod for movement longitudinally of said rod between a clamping position to clamp a wheel hub on a bicycle frame by placing said rod in tension and a release position to release said rod from said tension for releasing the wheel hub from the bicycle frame, said clamping means including a clamping head for engaging a bicycle frame, a reaction member separate from said clamping head and separate from said rod, connecting means connecting said reaction member to said second end of said rod for placing said rod in tension, and actuation means operatively interconnecting said clamping head and said reaction member for effecting relative movement between said clamping head and said reaction member in a direction longitudinally of said rod between said clamping and release positions, said actuation means including a cam member rotatably supported by said clamping head for rotation about a rotational axis which extends transversely of said rod, said cam member having an eccentric cam engaging said reaction member for effecting said relative movement between said clamping head and said reaction member, said second end of said rod including stop means engaging said eccentric cam for preventing rotation of said rod relative to said cam member and said clamping head, said eccentric cam being circular in cross section about an eccentric axis which is laterally displaced from said rotational axis, said stop means including an arcuate recess in said second end of said rod and concentric with said eccentric cam.
