Latest Patents
Among his most recent inventions is a door lock capable of showing its locking or unlocking state. This unique design features a latch driving device with a thumb turn that can be switched between three positions: a locking position that prevents movement of the latch, an unlocking position that allows the latch to move when the outer handle is pivoted, and an intermediate position. The thumb turn is equipped with an actuator controlling a switch that indicates the lock's status through a lighting element. When in the locking position, the switch is conductive, illuminating the light. Conversely, in the unlocking position, the switch is non-conductive, and the light turns off, making it easy for users to identify the lock's state visually.
Another significant patent involves a lock mechanism with a lighted display when in the locked position. This invention includes a controllable lock member and a signal generator that produces a detectable signal, enhancing the latch's engagement with the latch receiver. This mechanism comprises a dual-side latch driving device setup and can operate in a normal locked state or an emergency position where the signal generator is activated for alerting users.
