Abstract:

A door latch includes a latch support, a plurality of lever members, each lever member being rotatably secured to the latch support, a lever actuating handle rotatably secured to a first end of each of the plurality of lever members, and a latch plate. Manually moving the lever actuating handle rotates the plurality of lever members between a substantially vertical position and a substantially horizontal position. The plurality of lever members extend past the edge of the latch support when they are in the substantially horizontal position. For a door which opens inwardly, toward the door latch, the latch support is secured to the door frame and the latch plate is secured to the door. For a door which opens outwardly, away from the door latch, the latch support is secured to the door and the latch plate is secured to the door frame. When the plurality of lever members are in the substantially vertical position, the second end is in the up position and when the plurality of lever members are in the substantially horizontal position, the plurality of lever members are not allowed to go past the substantially horizontal position. In one arrangement, each lever member forms a wing at the first end. The lever actuating handle is rotatably secured to the wing of each lever member of the plurality of lever members. In this way, the plurality of lever members cannot go past the substantially horizontal position.
