发明名称 Simulated dead bolt lock for deterring burglars
摘要 This apparatus simulates the appearance of an actual dead bolt lock. When installed, the simulated dead bolt lock discourages would-be vandals from attempting to break into homes or businesses. The simulated dead bolt lock is installed on a door and includes a collar fastened to the door so that the collar resists rotation when fastened. The collar has a back surface, beveled side surfaces and a front surface. A recess is formed in the front surface of the collar to receive a keyway insert. The keyway insert has a keyhole, and is permanently secured within the recess on the front surface of the collar.
