Electric strike

摘要

An electric strike according to the present invention comprises a housing, and an actuator mounted to the housing to switch operation of said strike between open and locked modes. In changing the modes the actuator provides lateral motion and a blocking element is included that is also mounted to the housing and cooperates with the actuator. The actuator's lateral motion causes rotational movement in the blocking element to switch between said open and locked modes. Different embodiments of the present invention can operate as dual mode electric strikes wherein the actuator is movable between fail-safe and fail-secure positions, and can include switches and paddles to monitor the position or condition of certain mechanisms in or working with the strikes. In some embodiments the blocking element can be rotatably mounted to the housing at a plurality of rotation mounting points and can comprise a plurality of blocking surfaces. In other embodiments, at least one of the one or more blocking surfaces having a pre-load movement mechanism to reduce friction with the keeper.

1. An electric strike, comprising:
a housing; a keeper movably mounted to said housing; an actuator mounted to said housing to switch operation of said strike between open and locked modes, said actuator providing lateral motion; a blocking element mounted to said housing and cooperating with said actuator, wherein said actuator lateral motion causes rotational movement in said blocking element to switch between said open and locked modes; and a lever movably mounted to said housing, said lever moving in response to said actuator lateral movement and causing said blocking member rotational movement; wherein said lateral motion and the axis of said rotational movement are substantially parallel; wherein said lever has a slot and said blocking element comprising a finger in said slot, said lever movement causing said finger to move in said slot.
