  • Patent number: 3991520
    Abstract: A push to open door opening assembly for appliance doors including a single molded opening piece positioned between front and back panels of a substantially hollow door with a pushbutton section projecting through the front panel and an actuator ram projecting through the back panel. A fulcrum point is provided on the molded piece and an integral spring maintains the fulcrum against the front panel and the pushbutton projecting through the front panel. Actuation of the pushbutton pivots the device around the fulcrum against the spring to force the actuator ram from the rear panel into contact with an appliance cabinet wall thereby biasing the door away from the cabinet wall and overcoming a releasable closure device which maintains the door in a closed position.
