Abstract
A lock having a pair of jaws and a connecting shaft therebetween turnable in a first direction in response to a locking action of a key to cause the jaws to move inwardly and tightly grip against a spoked wheel rim or frame member of a bicycle and releasable only upon an unlocking action of the key to turn the shaft in an opposite direction. A cable may be connected between the jaws to allow the bicycle to be secured to a stationary object.
Claims8
A bicycle lock, comprising:
- a pair of jaws for gripping opposite sides of a rim of a spoked wheel in a direction generally parallel to an axle of said wheel, at least one of said jaws supporting a projection for engaging a fork-like frame member supporting the said axle when said jaws are affixed in place on said rim to limit rotation of said wheel, said jaws including coaxial holes;
- a connecting shaft turnable in said coaxial holes in said jaws, axially fixed relative to a fixed one of said jaws, and axially slidable in the hole in a movable one of said jaws;
- and
- cooperative means on said movable jaw and connecting shaft for (a) driving said movable jaw toward said fixed jaw and for (b) releasably locking said movable jaw against axial movement on said shaft away from said fixed jaw as said shaft is turned to a preselected rotational position relative to said movable jaw.
