ABSTRACT:
A security lock device for a side-by-side pair of hinged double doors which permits securely locking the doors to the opposing door jambs and to one another to thereby secure the same against forced entry. The security lock device comprises a pair of locking bar assemblies mounted on a common face of the pair of doors and extending generally horizontally thereacross. Each locking bar assembly includes an elongate central mounting bar extending widthwise of the door with a pair of slidable bars mounted along opposite sides of the central mounting bar and adapted for longitudinal sliding movement between a retracted unlocked position and an extended locked position. When in the extended locked position, the slidable bars interlockingly engage one another at the opposing inside edges of the doors where the doors meet and also engage the door jambs along the outside edges of the door to thereby maintain the pair of double doors in a tightly locked position.
