Electric lock
First Claim
1. An electric lock, comprising:
- a. an elongate housing adapted for mounting in a narrow door stile or frame member with the longitudinal axis of the housing being aligned with the longitudinal axis of the member;
b. a bolt supported in said housing for movement on an axis in right-angled relation to the longitudinal axis of said housing between a projected locking position and a retracted non-locking position;
c. means normally urging said bolt towards its retracted position; and
d. means for actuating said bolt to a projected locking position, which includes;
a solenoid mounted to said housing and having a plunger supported for axial movement on an axis having parallel relation with respect to the longitudinal axis of said housing,an angle lever in said housing and pivoted at one end for swinging movement and having an outer end adapted for surface engagement with an inner end surface of said bolt,a ball member interposed between said solenoid plunger and said angle lever, and means in said housing for guidingly supporting said ball for free movement in a path coaxial with said solenoid plunger,said axial movement of said solenoid plunger, acting through said ball to swing said lever in a direction to move said bolt to said projected locking position.

Abstract
An electric lock of a configuration to facilitate its mounting in the limited space of a conventional door structure or door frame structure, in which an actuating solenoid for the bolt is mounted so that its plunger will have an axis of movement in right-angled relation to the axis of movement of the lock bolt. In one embodiment, the lock includes a detent switch operable upon door closure to energize the solenoid for actuation of the bolt to a locking position. In another embodiment, the lock has an associated deadlock which operates automatically to lock the bolt in locking position, and is operable to a non-deadlocking position in response to energization of an associated solenoid. In still another embodiment of the lock, the bolt is normally spring-urged to a locking position, and the bolt actuating solenoid must be energized to maintain the bolt in a retracted non-locking position.

12. An electric lock, comprising:
-
a. an elongate housing adapted for mounting in a narrow door stile or frame member with the longitudinal axis of the housing being aligned with the longitudinal axis of the member; b. a bolt supported in said housing for movement on an axis in right-angled relation to the longitudinal axis of said housing between a projected locking position and a retracted non-locking position; c. means normally urging said bolt towards its retracted position; d. means for actuating said bolt to a projected locking position, which includes a solenoid having a plunger supported for axial movement on an axis having parallel relation with respect to the longitudinal axis of said housing; e. deadlocking means automatically operable to releasably lock said bolt in said locking position, said deadlocking means comprising; a member supported in said housing for movement between deadlocking and non-deadlocking positions; a first spring normally urging said member to its non-deadlocking position; and electrically energizable means for releasing said deadlocking member, including a second solenoid mounted to said housing and having a plunger normally urged by a second spring in a direction to move said member against the force of said first spring into said deadlocking position, said second spring having a greater urging force than said first spring, whereby upon energization of said solenoid said first spring will be operative to move said member to said non-deadlocking position. - View Dependent Claims (13, 14, 15, 16)
