ABSTRACT:
This invention is a bicycle lock, comprising a two-way horizontal swivel bicycle frame clamp which is secured by a nut and bolt to the bicycle frame. The clamp wraps around the bicycle frame just below the seat post and is secured in place by said nut and bolt. The lock also includes a 90.degree. pivot rod, one end of which is connected to said clamp and acts as a hinge, allowing the unit to move back and forth in a horizontal direction. Also included is a two-way cylinder which is attached to said pivot rod, permitting the unit to move back and forth in a vertical direction similar to the movement of a hinge. There are also flat metal tracks such that one end of one track is attached to said cylinder and the other end is connected to the other tracks, one after another in line, and held together by means of rivets. The rivets slide along the inside of the tracks, acting as a swivel and also allowing the tracks to extend or retract.
