ABSTRACT:
A secondary locking mechanism having a lock mountable to a sliding closure, such as a sliding window or sliding patio door, and a stop block mountable to a frame member which mounts the sliding closure. The lock has a pivotable stop arm which is spring-retained in an inactive position wherein a foot of the stop arm travels in a path of movement along with the sliding closure which is out of interfering relation with the stop block and an active position wherein the foot of the stop arm is positioned to engage beneath an inclined end of the stop block to prevent further movement of the sliding closure in a direction toward the stop block. One or more stop blocks can be mounted in various positions on the frame member to assist in locking the sliding closure in a fully-closed position and to prevent further opening movement of the sliding closure when it is in a partially-open vent position. In a patio door, the lock is mounted adjacent the bottom of a vertical edge of the sliding door and the stop block constitutes a floor stop in the form of a plate mounted to the sill of the patio door.
