  • Patent number: 5474345
    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.
