ABSTRACT:
A lock release mechanism which is operable in conjunction with a locking device on an access means, such as a hood into a portion of a vehicle, preferably an automotive vehicle. The lock release mechanism comprises an outer housing having a shiftable locking element therein. The shiftable locking element is locked when a shiftable plunger, such as a wedge, is biased into locking position. The lock release mechanism also includes a solenoid which is energized to remove the plunger from the locking position. When the plunger is removed from its locking position, the lock device on the access means can be operated.
The lock release mechanism is preferably designed for use in vehicles of the type equipped with a safety interlock system and which is electrically operable pursuant to the introduction of a preselected code through a plurality of manually operable input switches. In most cases, the safety interlock system comprises a plurality of latches which are operated in preestablished sequence when a preestablished code of indicia is introduced through manual operation of the plurality of input switches. When the latches are operated pursuant to the introduction of the preestablished code, the lock release mechanism may be operated.
