Claim 1
Independent Claim
151 words
A rattle-free, quick-release 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 axial 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 openings; a connecting shaft turnable in said coaxial openings in said jaws, axially fixed relative to a fixed one of said jaws, and axially slidable in the opening in a movable one of said jaws; and cooperative means including one-way ratchet means on said movable jaw and connecting shaft for releasably locking said movable jaw against axial movement on said shaft away from said fixed jaw when said shaft is in a preselected rotational position relative to said movable jaw.

A rattle-free, quick-release 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 axial 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 openings; a connecting shaft turnable in said coaxial openings in said jaws, axially fixed relative to a fixed one of said jaws, and axially slidable in the opening in a movable one of said jaws; and cooperative means including one-way ratchet means on said movable jaw and connecting shaft for releasably locking said movable jaw against axial movement on said shaft away from said fixed jaw when said shaft is in a preselected rotational position relative to said movable jaw.
Claim 3
Dependent Claim
66 words
The lock of claim 1 wherein said cooperative means comprises: a latching pawl extending into said opening in said movable jaw; and a row of teeth formed on one side of said connecting shaft for successively engaging said latching pawl with axial movement of said movable jaw toward said other jaw and for locking against axial movement of said movable jaw away from said other jaw.
Claim 4
Dependent Claim
97 words
The lock of claim 2 wherein: said movable jaw includes a cavity extending from said opening therein for receiving said latching pawl; and said latching pawl is secured in said cavity and includes a generally V-shaped spring member having one arm secured in said cavity and another arm extending from said cavity into said opening in said movable jaw in a direction away from said other jaw such that an end of said other arm successively engages and rides over said teeth with axial movement of said movable jaw along said connecting shaft toward said other jaw.
