ABSTRACT:
An electric strike having a pivotally mounted keeper for engagement by a door lock bolt or the like having a solenoid control, pivotally mounted locking lever and a pivotally mounted locking cam associated with the lever for releasably retaining the lever in blocking relationship to an abutment on the keeper for releasably retaining the keeper in position for engagement by the door lock bolt, thereby enabling the electric strike to be remotely controlled and operated. The locking lever and locking cam are provided with arcuately curved engaging surfaces which precludes the possibility of the locking cam surface being "walked" off of the locking lever by exerting pressure on the keeper while tapping or otherwise impacting the adjacent structure. The curved engaging surfaces of the locking cam and locking lever reduces wear. The solenoid is oriented externally of the casing and can be oriented in different relationships to the casing for installation in various types of doorjambs. Also, the solenoids may be oriented optionally to provide optional failsafe arrangements and the casing is provided with a plastic insert, such as nylon, which serves as a strain relief for the electric wires extending to the solenoid, signal switches, and the like.
