Abstract: 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.

Abstract: The present invention provides an improved electric lock that allows for electrically controlled retraction of latch bolt to allow for opening of the door in which the lock is installed. The components that allow for retraction are primarily internal to the lock and have means for conducting electrical signals to the lock to allow for remote control of the latch retraction. In some embodiments, the locks comprise an electrically controllable actuator and at least one retraction lever configured to retract the latch bolt against an applied bias. In other embodiments, the actuator can be housed within a separate housing can be configured to retract the latch bolt directly without using a retraction lever.

In some embodiments, the locks comprise an electrically controllable actuator and at least one retraction lever configured to retract the latch bolt against an applied bias. The actuator can be configured with various other internal components such that movement of the other internal components in one direction, such as toward the actuator, causes movement of the latch bolt in the opposite direction, such as away from the actuator. This opposing movement can allow for different electrical arrangements within different locks having relatively small internal spaces.
