Abstract
A lock mechanism is disclosed for use with sliding, swinging or overhead doors. A receiver is affixed to the door frame and a bolt, linkage and handle are affixed to the door. The linkage allows the bolt to engage the receiver by sliding along the receiver until it becomes latched so that the door may be closed though the handle is locked. Pulling upon the unlocked handle retracts the bolt from the receiver and also causes the door to start opening.
