Latest Patents
One of his latest noteworthy inventions is the "Electrified Exit Device." This sophisticated latch dogging assembly incorporates an electromagnet and an actuator mounted on a bracket. The device features a guide slide that pivots on the bracket and is connected to a lead block. With a guide pin traversing the inner surface of the bracket, this design allows for fluid movement, enabling the pawl to engage and interact with the armature mounted on the panic bar. When energized, the actuator moves the lead block, engaging the pawl and pivoting the armature, which transitions the panic bar from an extended to a depressed position. This mechanism ensures that the armature is magnetically held in place during operation, preventing any reverse pivoting of the assembly, thus providing a reliable solution for retracting door latches.
