Abstract
A sliding door lock having a latch plate, which slidably engages a channel in one leg of a corner piece. The corner piece is mounted in a door frame. A stud is attached to the slider plate so that a person may grasp the stud and slide the plate up and down. The stud has internal threads. A small screw is threaded into the internal threads of the stud. The sliding door lock is used by grasping the stud, which extends through an elongated slot in the door frame, and using the stud to move the latch plate upward so that it extends past the top of the door frame. The small screw is then used to hold the latch plate in an upward position. A tool is used to thread the small screw past the end of the stud so that the end of the small screw is in frictional contact with the corner piece, thus holding the latch plate in the upward position. When the latch plate is locked in the upward position, the door cannot be slid open because the upper end of the plate will come into contact with a block positioned above the door frame and mounted on a supporting structure surrounding the door frame. The latch plate may also be used in conjunction with other blocks for the purpose of holding the sliding door open.
