Abstract

A high strength bolt assembly for positive securement of doors and the like is disclosed. The assembly includes a pair of mounting elements adapted for mounting to a door and door frame, and a slide bolt mounted to one of the elements for sliding movement to and from a bolted position engaging the remaining element. The mounting elements include flange portions and the flange portions and the slide bolt are each formed with openings therethrough positioned to enable padlocking of the flanges and bolt together as a unit. The mounting elements further are preferably formed for access to the padlock locking the bolt assembly from either side of the door. In one embodiment the flanges are provided on each of the mounting elements and extend toward each other to overlap in side-by-side relation. In another embodiment, particularly well suited for sliding glass doors, the flanges are provided on a single mounting element.

Dependent claims

In a high strength bolt assembly for positive securement of a door, window or the like, said assembly including a pair of assembly mounting elements with a first of said elements being formed for mounting to said door proximate a door frame and a second of said elements being formed for mounting to said door frame proximate said first of said elements, and a bolt mounted to one of said elements for movement to and from a bolted position and an unbolted position, the improvement comprising:

said elements being formed to provide, as mounted on said door and door frame, adjacent flange portions defining a bolt receiving slot therebetween, said flange portions each spanning across the slot defined by the confronting edges of said door and said door frame when said door is in a closed position;
said bolt being mounted for movement into said bolt receiving slot upon movement to said bolted position and being mounted to span across the slot defined by the confronting edges of said door and said door frame in said bolted position;
and
said flange portions and said bolt each being formed with a channel therein dimensioned for receipt of lock means, and each said channel being positioned for aligned registration of all of the channels in a direction extending substantially parallel to the slot defined by the confronting edges of said door and door frame upon closing of said door and movement of said bolt to said bolted position, said elements being further formed and said channels oriented for positioning of said lock means therethrough for access to said lock and unlock the same from both sides of said door.

In a high strength bolt assembly for positive securement of double doors or the like, said assembly including a pair of assembly mounting elements with a first of said elements being adapted for mounting to a first of said double doors proximate a second of said double doors and a second of said elements being formed for mounting to said second of said double doors proximate said first of said elements, and a slide bolt formed for mounting proximate said elements and formed for sliding movement to and from a bolted position and an unbolted position, the improvement comprising:

said elements each being formed with flange portions formed to extend toward and overlap each other and the slot defined by the confronting edges of said double doors when said elements are mounted to said double doors and said double doors are in a substantially closed position;
said slide bolt being formed to overlap the overlapped flange portions and span across between said elements when said double doors are in a substantially closed position and said slide bolt is in said bolted position;
and
said flange portions and said slide bolt each being formed with a channel therein dimensioned for receipt of lock means and positioned for aligned registration of all of the channels in a direction substantially perpendicular to said doors upon positioning of said double doors in a substantially closed position and sliding of said slide bolt to said bolted position, said elements and said slide bolt being further formed for cooperative securement of said double doors against a forced opening independently of lock means positioned in said channels.
