Bicycle cable lock

Claim 2

A locking apparatus comprising: a housing having an external housing wall, first and second apertures in said wall, opposite side walls and a central axis; first and second cable storage reels disposed within said housing adjacent each other, each reel being adjacent an opposite side wall and being independently rotatable about said axis; a separate elongated flexible cable wound around each of said first and second cable storage reels with one end of each cable fixed to the reel and the other end free and extractable through one of said first and second apertures in the external housing wall; a coiled spring disposed within each cable storage reel for biasing said reel in a cable retracted position against rotational movement; means associated with each opposite side wall for securing one end of the coiled spring adjacent to said side wall; means fixed to the free ends of said cables for enabling said cables to be secured to each other; said separate cables being capable of being independently withdrawn and extended from said cable storage reels through said apertures to enable securing the ends thereof and of being automatically retracted onto said cable storage reels by the force of said biasing means when said cables are unsecured.

Claim 3

A locking apparatus according to claim 1 further comprising means for securing said apparatus to the frame of a bicycle.

Claim 4

A locking apparatus according to claim 2 wherein the free end of at least one of said cables terminates in a shackle.

Claim 5

A locking apparatus according to claim 2 further comprising locking means to secure the free ends of said cables together.

Claim 6

A locking apparatus according to claim 4 wherein said locking means comprises a combination lock, said combination lock comprising a female component affixed to the free end of one cable and a male component affixed to the free end of the other cable.

Claim 7

A locking apparatus according to claim 1 further comprising means for guiding the cables around their respective cable storage reel during extension and retraction thereof.

Claim 8

A locking apparatus as claimed in claim 6 wherein said guiding means is integrally formed with each reel.

Claim 9

A locking apparatus as claimed in claim 6, wherein said guiding means is in the form of a single, continuous groove in the form of a helix on the surface of the reel with said groove conforming in configuration to the cross-section of the cable so as to receive said cable therein and guide said cable onto and off of the surface of the reel upon retraction and extension thereof.

Claim 10

A locking apparatus as claimed in claim 1 wherein the housing is constructed of lightweight plastic.

Claim 11

A locking apparatus as claimed in claim 2 wherein said means for securing said apparatus to the frame of a bicycle comprises a first hollow semi-cylindrical member extending from the housing and integrally formed therewith and a second semi-cylindrical, member conforming in shape to the first semi-cylindrical member, said members being fastenable about a tubular bicycle frame fit snugly therebetween, and means for securing said semi-cylindrical members to each other.

Claim 12

A locking apparatus comprising: a housing having an external wall, first and second apertures in said external housing wall, opposite side walls and a central axis; first and second cable storage reels disposed within said housing adjacent each other with each reel being adjacent an opposite side wall, said reels being independently rotatable about said axis; a separate elongated flexible cable wound around each of said first and second cable storage reels with one end of each cable fixed to the reel and the other end free and extractable through one of said first and second apertures in the external housing wall; separate and independent biasing means in the form of a coiled spring disposed within each cable storage reel, said biasing means biasing said reel in a cable retracted position against rotational movement; means associated with each opposite side wall for securing an end of the coiled spring adjacent to said side wall; means fixed to the free ends of said cables for enabling said cables to be secured to each other; cable guiding means on the surface of each reel for guiding the cables around their respective cable storage reel during extension and retraction of said cables; said cable guiding means comprising a single, continuous groove in the form of a helix on the surface of the reel with said groove conforming in configuration to the cross-section of the cable so as to receive said cable therein and guide said cable onto and off of the surface of the reel; said separate cables being capable of being independently withdrawn and extended from said cable storage reels through said apertures in said external wall of said housing to enable securing the ends thereof together and of being automatically retracted onto said cable storage reels by the force of said biasing means when said cables are unsecured.

Claim 13

A locking apparatus comprising: a housing having an external wall, first and second apertures in said external housing wall, opposite side walls and a central axis; first and second cable storage reels disposed within said housing adjacent each other with each reel being adjacent an opposite side wall, said reels being independently rotatable about said axis; a separate elongated flexible cable wound around each of said first and second cable storage reels with one end of each cable fixed to the reel and the other end free and extractable through one of said first and second apertures in the external housing wall; separate and independent biasing means in the form of a coiled spring disposed within each cable storage reel, said biasing means biasing said reel in a cable retracted position against rotational movement; means associated with each opposite side wall for securing an end of the coiled spring adjacent to said side wall; means fixed to the free ends of said cables for enabling said cables to be secured to each other; cable guiding means on the surface of each reel for guiding the cables around their respective cable storage reel during extension and retraction of said cables; said cable guiding means comprising a single, continuous groove in the form of a helix on the surface of the reel with said groove conforming in configuration to the cross-section of the cable so as to receive said cable therein and guide said cable onto and off of the surface of the reel; said separate cables being capable of being independently withdrawn and extended from said cable storage reels through said apertures in said external wall of said housing to enable securing the ends thereof together and of being automatically retracted onto said cable storage reels by the force of said biasing means when said cables are unsecured.
