Abstract

The door latch includes a support bracket adapted to be mounted on the interior surface of an outer screen or storm door, an elongated bolt slidably and rotatably carried in a guideway on the support bracket, and a transversely extending handle on the bolt which extends through a slot in the guideway and is somewhat longer than the spacing between the outer door and an inner door. When the handle is in a generally horizontal operating position, the slot permits the bolt to slide freely between a latching position wherein the outer end is received in a keeper on the door frame and an unlatched position wherein the bolt is retracted from the keeper. Detent recesses located at the opposite ends of the slot permit the handle to be rotated downwardly to a generally vertical non-operating position when the bolt is in either the latching or unlatched positions and prevent sliding of the bolt unless the handle is rotated to the operating position. The handle cannot be rotated to the operating position for unlatching the bolt any time inner door is closed.
