Abstract
An electric door lock having a return means comprising a pair of locking members, a return member, rod guides, and leaf springs which eliminates the disadvantages of roller type pivot member locks. The lock is thinner to provide improved appearance. The locking members and return member may be connected to each other to ensure more reliable operation. A biasing force is applied to the locking members in the same direction as the pivotal movement of the locking members, and the engaging surface of the locking members does not apply force to the locking levers thereby making it possible to disengage the locking lever from the locking members using only a minimum of magnetic force and consuming only a small amount of electric power which can be conveniently supplied by a small DC battery.
