Abstract

A high strength security bolt assembly for double doors of commercial establishments and the like affords security on both sides of the door when in the active locking position bridging both door leaves. The device features separate self-contained assemblies which are mounted with through bolts on each door leaf and a sliding locking tube which spans or bridges components of each assembly when in the active locking position. The assemblies are reversible to accommodate any arrangement of active and inactive door leaves.

Claims

1. A security bolt assembly for double leaf hinged doors comprising a base mounting plate rigidly secured to one face of each door leaf and extending substantially thereacross horizontally, a relatively narrow web secured to each base mounting plate and projecting outwardly thereof and being substantially coextensive lengthwise therewith, a rectangular cross section bar forming a guide rail rigid with each web and substantially coextensive lengthwise with the web and maintained spaced outwardly from the adjacent base mounting plate by the web, each bar extending substantially equidistantly above and below the web and having horizontal faces above and below the web, a bridging locking member in the form of a rectangular cross section slotted tube slidable externally on both of said bars and being retractable bodily onto one bar so as to be completely separated from the other bar, said webs engaging through the slot of said tube and the slot being disposed on the interior side of the tube in opposing relation to the base mounting plates, and alignable elements adapted to be padlocked on the bridging locking member and on at least one of said bars.

2. The structure of claim 1, and a pair of apertured lugs on the bridging locking member near the opposite ends thereof adapted for padlocking with a pair of stationary apertured lugs adjacent to said bars.

3. The structure of claim 2, and rigid bolts on the outer ends of said bars adapted to enter openings of adjacent door jambs when the door leaves are closed and lie in a common plane.
