Abstract: A clamp for releasably securing a lock to a bicycle frame is disclosed. The clamp is formed as a unitary body of a hard yet resilient plastic material, which unitary body defines a pair of spaced tubular openings: one to fit about the frame and the other to hold the lock. The pair of tubular openings are axially split at their respective outer peripheries, with an arcuate segment being removed from each tubular opening along the respective splits. A pair of opposed parallel shoulders extend astride each of the splits, with each pair of shoulders featuring fastening means. Preferably, the plastic material is nylon. Preferably, one of the pair of spaced tubular openings is tapered along its axial length.

Abstract: A locking device for securing a bicycle or the like to a post or other fixture. The locking device features a replaceable lock cylinder, which in turn allows for both replacing merely the lock cylinder when the keys get lost and also allows for conforming the lock cylinder of the device to an identical lock cylinder used in the owner's home so that one key, preferably a flat key, services both the device and the home. The lock cylinder cannot, however, be removed when the device is locked and in use. The key, on the other hand, can only be removed when the device is locked.

Abstract: A bracket is provided for carrying and/or storing a large U-shaped lock used to secure a motorcycle or the like by passing the U-shaped shackle through the wheel of the bike and closing the ends of the shackle by means of a cross bar locked thereto. The bracket is comprised of a flat body portion along at least one edge of which is formed a tubular or semi-tubular receptacle adapted to receive a leg of the U-shaped lock shackle. Mounted to the body portion is a fastening device for engaging the cross bar of the lock to prevent longitudinal movement thereof with respect to the bracket. The bracket when used on a motorcycle preferably is mounted against the shock absorber for the rear wheel thereof.

Abstract: A locking mechanism and storage bracket are provided for use in securing bicycles or the like to a post or other fixture. The lock includes a relatively large U-shaped shackle formed from cylindrical hard metal stock, one leg of which terminates in a bent foot portion. The other leg extends parallel to the first leg and is formed with a shoulder near the end thereof. The lock also includes a tubular cross piece formed with a pair of openings in register with the ends of the shackle legs and provided with a key operated lock in one end of the cross piece adapted to lock with the shoulder of the other shackle leg when assembled thereto. The bent foot portion locks to the cross piece by inserting the end of the foot in its cooperating opening and pivoting the shackle to bring the end of the other leg into its opening where it is secured by the key operated lock.
