Abstract

The bicycle lock includes a housing structure secured to the frame of the bicycle under the seat adjacent to the rear bicycle wheel. A C-shaped member is pivoted to the housing structure for movement from an unlocked position to a locked position wherein the member passes under the rear tire and rim portion of the wheel. In addition, the housing includes a spring-loaded cable with one end exposed which can be pulled from the housing and looped about a stationary object such as a post and then re-inserted through an entrance opening in a side of the housing so that the wheel of the bicycle is not only locked against rotation but the bicycle itself is secured to a stationary object. A single cylinder-tumbler type key operated lock functions to simultaneously release the C-shaped member from its locked position and the one end of the cable from the entrance opening.

Dependent claims

A bicycle lock comprising, in combination:

a. a housing having first and second legs extending downwardly in a given position to straddle opposite sides of a tire and rim portion of the bicycle wheel;
b. a C-shaped member pivotally mounted in an upper part of said housing such that the lower arm of the member can swing from an unlocked position in the lower end of said first leg of the housing into a locked position in the lower end of the second leg of the housing underneath said tire and rim of said bicycle wheel so that the tire and rim are wholly surrounded by the combination of the legs of the housing and the lower arm of the C-shaped member;
c. a cable coiled within said housing with one end extending from a side of the housing such that the cable can be pulled from the housing and looped about a stationary object, said second leg of said housing having an entrance opening for receiving said one end of the cable;
and
d. a single locking means in said second leg operable to separately or simultaneously lock the lower arm end of said C-shaped member and the one end of said cable in said second leg, and simultaneously unlock the same when operated whereby said bicycle is secured against theft.

2 more elements

A bicycle lock including, in combination:

(a) a housing structure;
(b) a swingable member pivoted in said housing structure for movement from an unlocked position to a locked position wherein said member passes under a wheel tire and rim portion of said bicycle;
(c) a cable stored in said housing with one end exposed so that the cable may be pulled from the housing and looped about a stationary object, said housing including an entrance opening for receiving said one end of said cable;
(d) locking means in said housing for locking said swingable member in its locked position and said one end of said cable in said housing, said locking means including a rotatable cylinder-tumbler type key operated lock and wherein said member and said one end of said cable each have notches, said locking means further including bolt means biased towards said notches and receivable therein when said member is swung to its locked position and said one end of said cable is received in said entrance opening, said bolt means being coupled to said cylinder and responsive to rotation thereof to move away from said notches, whereby said one end of said cable and said swingable member are secured in their locked positions and whereby the same or unlocked simultaneously in response to a single rotative motion of said cylinder-tumbler type key operated lock;
and
(e) bracket means for securing said housing to a frame portion of said bicycle adjacent to said wheel tire and rim portion, said bracket means being secured to said frame portion and including fastening openings positioned to register with fastening openings in said housing, said swingable member including access areas registering with said fastening openings when said member is in its unlocked position so that fastening means may be passed through the access areas to secure the housing to the bracket means, swinging of said swingable member to its locked position resulting in the eclipsing of said openings by areas of said member adjacent to said access areas so that when the swingable member is in its locked position, fastening means within said fastening openings cannot be removed.
