ABSTRACT:
Apparatus for preventing the opening of a movable closure--such as a pivoted door--from either side thereof. First and second rods are pivotedly mounted together to be folded up for storage or transport, or to be disposed in end-to-end relationship when the apparatus is operative. A third rod slides with respect to the first and second rods and operatively engages the first and second rods to lock them together in end-to-end relationship. A fork for engaging the door knob is provided at one end of the rods, and an engaging member for securely engaging either a carpet or a smooth floor is provided at the other end of the rods. A chain having an enlarged loop at one end and an elongated pin at the other end cooperates with a tubular member formed on the rods to facilitate locking of a pivoted door from the jamb side thereof.
