ABSTRACT:
A quick-release bicycle axle fastener for standard hollow axles and standard safety drop-outs, comprising a control rod through the axle; a mount attached to one or both ends of the control rod; a cam lever attached to each mount; a washer with a finger grip, slidably mounted on the control rod inboard of the mount, shaped to engage the safety drop-out when pressed against it; and a spring urging the washer against the drop-out at all times. The cam forces the washer inward against the drop-out for clamping attachment of the wheel axle to the drop-out. When cam pressure is released, the interlock washer continues to be urged against the drop-out by the spring for safety until the washer is pulled outward by the fingers of a user. When the wheel is re-installed, the washer automatically shifts into engagement with the coupling surface of the drop-out, providing an automatic, undefeatable safety backup for the cam.
