ABSTRACT:
A device is adapted for use primarily as a theft deterrent for bicycles, mopeds and other two and three wheeled self propelled or motorized conveyances, said device comprises a pair of opposed, telescopically engaging U-shaped members and locking means associated with said members, securing them from being forcibly pulled apart. The locking means typically includes the use of a pawl and ratchet arrangement for facilitating the engagement of the two members for securing them in locking relationship. The device also includes a compressible and extendible rubber or elastomeric boot preferably in the form of bellows. This boot provides a protective cover around ratchet teeth that are longitudinally spaced along one of the arms of the two U-shaped members. The boot progressively surrounds the ratchet teeth as the rod is disengaged or withdrawn from the sleeve. The cover serves to prevent damage to the individual ratchet teeth, and in addition, provides a level of protection from scratching, chipping or marring the paint or other finish on the bicycle, etc. and injury to persons utilizing or otherwise coming into contact with the security device.
