Abstract

A horizontally adjustable door hinge, for hingedly connecting the vertical edge of a door to the adjacent vertical edge of the door frame, is secured upon an elongated metal strip which forms one of said edges. An enlarged opening cut in the strip loosely receives one leaf of the hinge. A plate overlaps the opening at the rear surface of the strip, and, the plate rear surface is overlapped by a back-up plate. The plate is rigidly fastened to the strip rear surface, and the back-up plate is secured to the plate by a mechanical fastening means that permits horizontal movement of the back-up plate relative to the fixed position plate. A number of sets of aligned screw receiving holes are formed in the leaf, plate and back-up plate. The holes in the plate are formed as horizontally elongated slots. At least some of the holes in the back-up plate are threaded, while others are of sufficient diameter to loosely pass a screw therethrough. Short screws extend through the aligned holes which include the threaded holes and when tightened, fasten together the leaf, plate, and back-up member. When the screws are loosened, the leaf, together with the back-up plate, may be horizontally moved relative to the plate and the strip. Other long screws extend through the other holes for embedding within a door or frame substrate, upon which the strip is applied, after the leaf is horizontally adjusted to predetermined location.

Dependent claims

A horizontally adjustable hinge system for hingedly connecting the vertical edge of a door to a vertical frame edge, comprising:

a vertically elongated, flat metal strip forming one of said edges and having an exposed face and a rear face, with said strip having a vertically elongated opening formed therein;
a hinge having a flat leaf loosely fitted within said opening and arranged generally in the plane of the strip, and a second leaf pivotally connected to said flap leaf and adapted for securement to the other of said edges;
a vertically elongated plate overlapping said opening and having end portions overlapping and rigidly secured to the strip portions immediately above and below the upper and lower ends of the opening;
and with the plate being arranged so that its central portion, which overlaps the strip opening, is substantially flat, and parallel to the strip for face-to-face contact with said flat leaf;
a flat, back-up plate member of about the same size as, and overlapping in face-to-face contact, the rear face of the plate;
means fastening said back-up plate member to said plate for providing limited horizontal movement only of said back-up plate member relative to said plate;
a number of screw holes formed in the leaf, and corresponding horizontally elongated slots formed in said plate in alignment with each screw hole, and aligned screw receiving openings formed in the back-up plate member;
short screws extending through certain of the leaf screw holes and through their aligned plate horizontal slots and being screw threaded within their aligned back-up plate member screw holes, for screw fastening the leaf to the back-up plate member, so that loosening of such screws permits horizontal movement only of the leaf relative to the plate and said strip.
