Patent number: 10815692Abstract: 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.Type: GrantFiled: August 27, 2014Date of Patent: October 27, 2020Assignee: Security Door ControlsInventors: Arthur V.

Patent number: 10697202Abstract: An electronic cathode lock includes a base formed with an opening that is communicated with an accommodating chamber in the base. In the accommodating chamber, two retaining units are provided symmetrically at two sides of the opening, and two driving units are provided corresponding to the retaining units. The two driving units are configured to position the retaining units to overlap the opening, or make the retaining unit move away from the opening. Thereby, the electronic cathode lock limits a latch in the accommodating chamber or makes the latch get out of the accommodating chamber. Such electronic unlocking of the electronic cathode lock is configured to work with a mechanical lock, thereby electronizing the mechanical lock.Type: GrantFiled: January 17, 2017Date of Patent: June 30, 2020Assignee: Security Door ControlsInventors: David A.

Publication number: 20170268256Abstract: 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.Type: ApplicationFiled: May 31, 2017Publication date: September 21, 2017Inventors: Arthur V.

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. 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.Type: ApplicationFiled: March 21, 2016Publication date: September 22, 2016Inventors: Arthur V.
