ABSTRACT:
A door lock which can be slipped from the inside between the edge of a door and the jamb into the latch plate carried thereby and adjusted to engage the door and prevent inward swinging. It is made as a single assembly consisting of a narrow carrier strip which has a lug on its outer end for engaging the latch-receiving opening and a carriage slidable thereon which carries a pivoted locking lever having an outer end for engaging the inner face of the door and an inner end which has a restraining portion that is biased into engagement with the adjacent face of the carrier strip and which will engage the strip more firmly when inward pressure is exerted on the door. The carriage also carries a releasing lever for engaging the locking lever to swing it in a reverse direction to release the restrainer portion from the strip and permit inward sliding movement of the carriage to disengage the outer end of the locking lever from the inner face of the door.
