  • Patent number: 7055874
    Abstract: The door handle bracket and latch assembly of the present invention includes a bracket subassembly and a latch. The latch has a spring mounted rotor and a spring mounted catch which function to maintain a door in a latched or unlatched condition. The bracket subassembly includes a mounting plate, a pivotally mounted trip lever, and a rotational release cam receiving the drive shaft of the door handle. Upon rotation of the door handle in either a clockwise or counterclockwise direction, the release cam pivots the trip lever, which in turn pivots the catch out of retentive engagement with the rotor, such that the rotor rotates to the unlatched position to allow the door to move from the latched closed position to an unlatched open position. The assembly has a simple design with a low profile and versatile mounting options.

  • Patent number: 6708537
    Abstract: A door lock assembly is provided for use on multiple types of door latches. The assembly includes a housing, a paddle pivotally mounted on the housing, and a pivot plate pivotally mounted on the housing and operatively connected to the door latch. An actuator is mounted on the housing and is operatively connected to the paddle. A pin is slideably received within a slot in the pivot plate and moved between first and second positions in response to locking and unlocking of a locked cylinder. The actuator engages the pin in the first position so as to actuate the pivot plate and thereby open the door latch when the paddle is pulled. The actuator disengages the pin in the second position so that the paddle free floats when pulled and precludes the pivot plate from opening the door latch when the locked cylinder is locked or the power actuator is actuated.
