  • Emergency deadbolt device with single action unlock
    Patent number: 11873664
    Abstract: The unlocking mechanism of the present invention is actuated as a result of contact with the door's existing lever. When an occupant rotates the door's lever, it not only retracts the door's latch, but the handle will also engage the unlocking mechanism of the present invention, the door lever engaging the unlocking mechanism. The door's lever follows the geometry of the cam thereby pushing the sliding bar of the unlocking mechanism thereby engaging a latch release. The latch release moves the locked lever of the door's deadbolt assembly and the deadbolt is retracted. When the door's lever is returned to its normal state, a spring pushes the sliding bar backward to the ready position. The latch release rotates to its ready position and the mechanism is ready for a subsequent activation.
