Abstract:

The present invention defines an anti-theft device for use with a variety of personal property, including bicycles, motorcycles and other small vehicles employing a three-part assembly of high-impact glass-filled nylon which attaches to vehicle frames of various size. The fastening means is hidden and sound channels are utilized to enhance an audible alarm and to prevent muffling of an interior speaker, activated by partial cutting or disconnection of a cable of known resistance. The cable is inserted in a case assembly with differing positions depending on whether the user wishes to set the alarm or store the cable out of the way if not energized. The alarm may be silenced by incrementally turning a key and removing a cable. The same key is positioned to allow arming of the alarm by insertion of the cables in the proper orientation. Further, the same key, turned another increment allows removal of the front cover of the assembly exposing the power source and electronics and allowing the unfastening of the assembly from the frame.
