Abstract
The self-locking guillotine door assembly includes a door, a locking mechanism attached to the door, and a cable attached to the locking mechanism. Pulling the cable releases the locking mechanism and lifts the locking mechanism and door. Pushing up on the bottom of the door locks the locking mechanism and resists lifting the door. The locking mechanism can include a post, a vertical slide with a slot, connector bars and cams such that when the cable is pulled, the cable lifts the vertical slide to lift proximal ends of the connector bars, which pivots the cams to release the locking mechanism. When the enclosure door is pushed up from the bottom, the locking mechanism pivots the cams towards the top of the enclosure door to lock the locking mechanism and resist lifting of the enclosure door.
