Abstract

Abstract This invention relates to a kit for reinforcing door hinges and, more specifically, to a two-piece kit for strengthening door hinges that may have come loose. The kit comprises a two-piece hinge repair kit that is adapted for use with standard size doors and with standard size hinges. The first piece of the kit is a rectangular U-shaped bracket having an open side or face. This U-shaped bracket is adapted to fit through its open side around the edge of the door. The sides and roof of this U-shaped structure have apertures to be used as connecting holes for attachment to the door and hinge. The roof has a recessed cutout section containing the holes for alignment with the holes of a hinge. The cutout distance down from the top of the roof should approximate the thickness of one leaf of the hinge. Thus, when the hinge is attached to the U-shaped bracket and door, the top surface is level with the face of the bracket and flush with the face of the roof sides adjacent the cutout portion. The vertical sides of the U-shaped bracket extending down from the roof portion contain screw holes for attaching the U-shaped bracket to the side edge portion of a door. This U-shaped mounting bracket is merely slipped over the door with some of its roof apertures aligned with the existing screw holes so that no adjustment or further chipping away of the door edge is required.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 246 words
A reinforcement hinge repair kit comprising only two one piece brackets, a first and second bracket, the first one piece bracket being an elongated U-shaped structure with a roof portion and two side sections extending down from and disposed at substantially right angles to said roof portion to form an open face, said roof portion having three sections, a center section and two end sections, said center section depressed downward from surfaces of said end sections, the distance from the plane of said center section to the plane of said end section being substantially the same as the thickness of a standard hinge leaf wherein when the hinge leaf is attached to the first bracket the top surface of the hinge leaf is level with the roof portion end sections to thereby prevent impedement of the closing of the door and the function of a hinge, said center section having apertures therein which will align with standard hinge leaf holes when in use, said end sections having apertures therein for receiving screws for attachment of said first bracket to a door edge, said second one piece bracket having a bar-like configuration with apertures therethrough to accommodate attachment of said second bracket to a door frame and also to accommodate attachment to a hinge leaf, said first hinge bracket being slipped over the door edge to repair and strength the door edge and to permit the hinge to be secured to a damaged or cracked door edge.
Claim 2
Dependent Claim 246 words
A reinforcement hinge repair kit comprising only two one piece brackets, a first and second bracket, the first one piece bracket being an elongated U-shaped structure with a roof portion and two side sections extending down from and disposed at substantially right angles to said roof portion to form an open face, said roof portion having three sections, a center section and two end sections, said center section depressed downward from surfaces of said end sections, the distance from the plane of said center section to the plane of said end section being substantially the same as the thickness of a standard hinge leaf wherein when the hinge leaf is attached to the first bracket the top surface of the hinge leaf is level with the roof portion end sections to thereby prevent impedement of the closing of the door and the function of a hinge, said center section having apertures therein which will align with standard hinge leaf holes when in use, said end sections having apertures therein for receiving screws for attachment of said first bracket to a door edge, said second one piece bracket having a bar-like configuration with apertures therethrough to accommodate attachment of said second bracket to a door frame and also to accommodate attachment to a hinge leaf, said first hinge bracket being slipped over the door edge to repair and strength the door edge and to permit the hinge to be secured to a damaged or cracked door edge.
