ABSTRACT:
A locking or latching device for double panels sharing the same opening or frame serves to secure the two panels together, to provide additional security over separate locks or latches for the two panels. The device is particularly adapted to securing two adjacent doors together (e.g., at outer storm door or screen door and a main entrance door for a residence or other structure), but is also adaptable to other double panels or closures, such as windows of various types and their associated shutters. The mechanism comprises a first generally cylindrical component which secures through the outermost panel or door, a second generally cylindrical component which secures through the adjacent relatively inner panel or door and is coaxial with the first component, and a rod which passes coaxially through the two cylindrical components. The rod is captured within the first component and extends through the second component when the two panels are closed and has a series of circumferential slots or grooves therearound. A latch secured to the inner end of the second component engages one of the slots in the rod to prevent its being withdrawn from the second component, thereby securing the two panels together. The multiple slots in the rod provide for adjustability, but still provide for rapid disengagement of the assembly so the doors may be opened quickly in the event of an emergency.
