Abstract

Abstract This is a bicycle lock specifically designed to be locked around the wheel of a bicycle to prevent rotation thereof and having sufficiently large cross sectional dimensions to prevent any portion thereof from being received between the jaws of a lever action cutter tool.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 190 words
A wheel-surrounding bicycle lock unit comprising; a pair of generally semi-circular similar locking segments each having mating overlapping end portions of reduced thickness and forming a body defining a wheel-surrounding opening therethrough when said segments are in closed position, the cross sectional dimensions of said segments when in wheelsurrounding locking position being sufficiently large to prevent the same from being received between the open jaws of a lever action bolt cutter and the cross sectional dimensions of at least a portion of the segments being sufficiently small to pass between the spokes of a bicycle wheel, a pivot pin connecting the mating overlapped end portions at one end of said segments to permit said segments to be opened to provide access to said opening and permit a bicYcle wheel to be received therein, and locking means mounted in the mating portion of one segment at the other end thereof and having a locking element disposed in generally parallel relation to said pivot pin and projectable into the adjacent overlapping mating portion of the other segment for securing the two segments of the body together when in closed wheel-surrounding locking position.
Claim 2
Dependent Claim 190 words
A wheel-surrounding bicycle lock unit comprising; a pair of generally semi-circular similar locking segments each having mating overlapping end portions of reduced thickness and forming a body defining a wheel-surrounding opening therethrough when said segments are in closed position, the cross sectional dimensions of said segments when in wheelsurrounding locking position being sufficiently large to prevent the same from being received between the open jaws of a lever action bolt cutter and the cross sectional dimensions of at least a portion of the segments being sufficiently small to pass between the spokes of a bicycle wheel, a pivot pin connecting the mating overlapped end portions at one end of said segments to permit said segments to be opened to provide access to said opening and permit a bicYcle wheel to be received therein, and locking means mounted in the mating portion of one segment at the other end thereof and having a locking element disposed in generally parallel relation to said pivot pin and projectable into the adjacent overlapping mating portion of the other segment for securing the two segments of the body together when in closed wheel-surrounding locking position.
Claim 3
Dependent Claim 49 words
The structure set forth in claim 1 wherein the minimum cross sectional dimension of said segments when in closed position is at least 1 inch and the maximum cross sectional dimension of the portion passing between the spokes of the bicycle wheel being no greater than 1 5/8 inches.
Claim 4
Dependent Claim 38 words
The structure set forth in claim 1 and said locking means including a threaded locking element threadably connecting adjacent portions of said segments when in closed position with means permitting rotation of said locking element only when unlocked.
Claim 5
Dependent Claim 45 words
The structure set forth in claim 3 and said means permitting rotation of the locking element comprising a key actuated mechanism having retractable anti-rotation locking elements permitting rotation of said threaded portion only when a key of the proper configuration is inserted into said mechanism.
Claim 6
Dependent Claim 154 words
The structure set forth in claim 1 and said locking means including, a threaded opening in the other ends of one of said segments, a lock casing having a cylindrical chamber therein and fixed to said other end of the other said segments, and axially aligned with the threaded opening of the other segment when in closed position, and having a keyway in the wall of said chamber, a lock core having an axially oriented key opening and a plurality of spring biased tumblers mounted transversely of said opening and normally urged into said casing keyway to prevent rotation of said core unless a key of the proper configuration is inserted into said opening to retract said tumblers from said keyway, a threaded locking element extending axially inwardly of said lock core and fixed thereto for projection into the threaded opening of the other segment aligned therewith when said segments are in closed position.
