Abstract
Abstract A security system for bicycles, ski racks and coat racks which includes a control in which a user can place a specific code for the specific lock which is to be used after which a free end of the cable can be passed through the device to be secured such as a bicycle, coat or a pair of skis and then inserted into the receptacle which locks. The security system includes an alarm when the cable carries either an electrical, a fibre optic or a pneumatic line such that if the cable is severed by a thief that an alarm system will instantly be actuated so as to prevent the theft. The user can release the cable by entering the known code when the article is to be removed which allows the one end of the cable to be unlocked from its holding socket.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
165 words
A locking system comprising, a holding member, a flexible locking cable with its first end attached to said holding member and adapted to be passed through an article which is to be locked to said holding member, the second end of said cable formed with a locking shoulder, a pair of locking jaws attached to said holding member and said second end of said cable insertable therein to lock said jaws behind said shoulder, a flexible conduit means which extends through said cable from said first to said second end, an energy transmitter connected to one end of said flexible conduit, and an energy sensor coupled to the other end of said flexible conduit to detect when said cable and flexible conduit are severed, including a micro-controller connected to said locking jaws to lock and unlock them, including a solenoid connected to said locking jaws and to said micro-controller and including an alarm connected to said micro-controller and said energy sensor connected to said micro-controller.
