ABSTRACT:
An adjustable latch assembly for the lock assembly of a pull-down door used to close a container space such as the cargo bay of a van or van body of a truck or similar vehicle. The adjustable latch assembly includes a face plate designed to be mounted flush with the floor of the truck bed. The face plate has elongated openings on either side thereof for receiving the locking tongue of a lock assembly. The opposing openings are separated by a bridge surface which covers the adjustable latch mechanism of the present invention. The adjustable latch mechanism includes opposing legs protruding from either side of the bridge with a foot on the opposite end of each leg. Each of the legs has an elongated slot that serves as a guide mechanism for the adjustable latch striker extending beneath the bridge and substantially parallel to it. The striker has opposing ends with holes bored through each opposing end. On one end, the hole passes over a guide journal, and the hole on the opposite end is threaded and receives a threaded adjustment bolt. Turning the threads of the bolt will cause the striker to raise or lower depending on the direction of rotation of the adjustment bolt. This allows the striker to be adjusted so that in the event the door fails to seal the cargo area of a van, the adjustment bolt can be turned, lowering the striker and thereby causing a greater downward force to be placed on the door when the tongue of the lock assembly is engaged beneath the striker and pivoted into a locking position. The guides on both sides of the striker hold it in alignment and keep it from jamming or otherwise binding when the striker is adjusted from time to time.
