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 A latch secured to the inner end of the second component engages one of the slots in the rod to prevent its being withdrawn from the second component, thereby securing the two panels together.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.

A double panel lock in combination with facing first and second panels for providing for the securing of the facing first and second panels together, said lock comprising: a rod extending inwardly from the first panel, with said rod having an attachment end secured to the first panel and an opposite latch engaging end having at least one circumferential groove therearound; a cooperating hollow latch cylinder disposed,through the second panel and captured therein and in coaxial alignment with said rod, with said latch cylinder having an outer end and an opposite inner end; a latch plate pivotally secured to said inner end of said cooperating latch cylinder, with said latch plate having a thickness less than said at least one circumferential groove of said rod and a pivot axis disposed parallel to said latch cylinder, so that said latch plate pivots across said inner end of said latch cylinder, whereby; the first panel and second panel are positioned in proximity to one another so that said rod extending inwardly from the first panel extends through said hollow cooperating latch cylinder captured in the second panel with said at least one groove of said rod in alignment with said latch plate, and said latch plate is pivotally moved to engage said groove of said rod to preclude the withdrawal of said rod from said latch cylinder and the separation of the first panel and second panel.
