Abstract: The double door security device uses at least two opposed hinges of the double door pair to secure corresponding door bar retainers to the door frame structure. The hinge pin is removed and the door bar retainer is placed upon the hinge, with a hinge pin of suitable length reinstalled through the hinge to secure the door bar retainer pivotally to the hinge. The door bar retainer, in combination with the hinge, defines a door bar passage for the removable installation of a door bar therethrough. The retainers may be configured to accept door bars having various cross sectional shapes, e.g. two by four lumber, square and round tubing and pipe, etc. The hinge attachment ends of the retainers are preferably beveled to minimize marring of the door and door frame adjacent to the hinge, and to serve as a door stop limiting the opening swing of the door.

Abstract: A rest for a firearm or the like that attaches to the sling swivel on the forearm of the firearm. Said rest is comprised of two major assemblies. First assembly attaches to the sling swivel and provides a surrogate sling swivel and a female receptacle for the second assembly. Second assembly consists of male protrusion that mates with first assembly and two lightweight legs that can be quickly assembled and disassembled. Said rest allows quick attachment and detachment in the field. With a static leg position, said rest allows the ability to move the muzzle of the firearm in a conical motion, and randomly within the confines of the cone, while concurrently adjusting the cant of the rifle.
