ABSTRACT:
Herein is disclosed a novel locking mechanism for a sliding window or door of the type having an outer surrounding rectangular frame mounted to a wall, and an inner transparent pane mounted to a second rectangular frame slidably mounted within the outer frame. The locking mechanism is incorporated within one side of the inner frame and comprises a slide, a latch adapted to move and lock the slide, a deadbolt attached to the slide and adapted to extend into the outer frame to lock the two frames together, and a latch accessed through a latch port defined in the side of the inner frame. The latch port comprises a wider locking segment and a narrower adjacent unlocking segment, and the latch comprises a post attached to the slide and a button slidably mounted on the post and sized to extend through the wider locking segment of the latch port. A coil spring surrounding the post forces the button into the wider locking segment when the deadbolt is in the lock position, thus maintaining the latch and slide in a vibration-resistant configuration until the button is depressed through the wider locking segment and transported along the unlocking segment of the port.
