ABSTRACT:
A door latch includes a plate member secured to the door jamb and extending therefrom generally parallel with one side of the door in its closed position. A stud on the plate member extends through an opening in the door in the closed position thereof and has an end portion projecting beyond the other side of the door. The end portion of the stud is bifurcated by having an open-ended slot formed therein. An elongated latch member has an elongated, inclined slot formed therein, the latch member being pivotally connected to the end portion of the stud by means of a pin spanning the two legs of the end portion and extending through the slot, the latch member being thereby pivotally movable from a first position extending axially outwardly from the stud to permit opening and closing of the door, and a second, latching position in which one side of the latch member engages the other side of the door in its closed position, the inclination of the slot providing a wedging action in co-operation with the pin so as to wedge the side of the latching member against the other side of the door.
