ABSTRACT:
A door locking mechanism for use on the inside of a pair of outswinging doors mounted in the opening of a frame in which the doors are hinged at opposite edges and having free edges adjacent each other and free to be moved between the opening and closing of the doors. The mechanism comprises extended members U-shaped in cross section mounted on the doors. One end terminates substantially flush with the free edge of each door. A latch plate is mounted for sliding movement within one U-shaped member. The latch plate is provided with a handle extending through a slot in the U-shaped member which can be employed to move the latch plate. The latch plate is moved between a closed position wherein the latch plate extends past the free edges of the doors to overlap the second door and an open position where the plate is entirely within the width of the first door. A lever is provided to clamp or unclamp the latch plate in either the open or closed positions. The second extended U-shaped member mounted on the second door receives the latch plate in the closed position. Provision is made to lock the latch plate in both the closed and open positions of the latch plate.
