CLOSURE LOCK

摘要

A closure lock for a folding door having top and bottom locking bars in the tubular post at the leading end of the door. The locking bars are normally biased to an unlocked position within the door. The bars can be manually moved to project from the ends of the post in a locked position. A single locking finger in the post automatically holds the locking bars in their locked position. A cylinder lock on each side of the post can be operated to move the locking finger to a position allowing the locking bars to withdraw to an unlocked position.
