Abstract

A door closure preventing device is mounted on the inside surface of a door and has a pivotal stop moveable between a deactivated position within the periphery of the door and the extended position extending beyond the periphery of the door to prevent closure of the door. The pivotal stop is moved to its extended position following opening of the door by a user and is then released to move by a spring to an intermediate position projecting beyond the door periphery following which closure of the door results in engagement of the door jamb by the stop to prevent complete closure. Engagement of the stop with the door jamb also returns the stop to is fully extended position and actuates a rotary latch so that upon subsequent opening movement of the door by the user the stop is automatically returned to its fully retracted position to permit a conventional door closure apparatus to fully close the door.
