Top-mounted double-action door hinge

A double-acting heavy-duty spring-biased door-hinge device comprising in combination:

• mounting means for supporting spring and hinge elements, having door-jamb-mounting structure adapted to be mounted on a substantially upright inwardly-directed door-jamb surface, and having spaced-apart substantially parallel first and second flanges extending in a common direction from the door-jamb-mounting structure, and for each of the flanges there being a pivot means providing a pivot pin and a pivot-pin-receiving space positioned for mounting opposite ends of a hinge-structure by the pivot pins at opposite ends thereof, said flange having a base, at least a first one of the pivot-pin-receiving spaces at said first flange being formed as an elongated slot extending in said common direction toward a base of the flange adapted for the pivot-pin to move transversely therein when a hinge-structure is supported thereby on said first flange, a hinge-structure at a first-end thereof being mountable by said pivot means on said first flange by a first pivot-pin extending axially substantially parallel with a longitudinal axis of a length of the hinge-structure adapted for pivot thereon of the hinge-structure, the first pivot-pin being mounted and ridable within said elongated slot in a direction transverse to the longitudinal axis of the first pivot-pin, said door-jamb-mounting structure at said first-end one of said flanges having a substantially flat surface extending substantially transversely across a longitudinal axis of the door-jamb-mounting structure such that the substantially flat surface is substantially parallel to the inwardly-directed door-jamb surface when mounted, said hinge-structure including an abutting means having abutting-structure at said first flange positioned at at-least two spaced-apart points along a plane substantially parallel to said substantially flat surface and in juxtaposition thereto such that one or the other of said spaced-apart abutting structure portions contact and slide along the flat surface when the hinge-structure is revolved pivotally in one of opposite directions on said first pivot pin whereby the first pivot-pin moves transversely in said elongated slot, and at-least one coil spring means extending in a direction substantially parallel to axes of each of said door-jamb-mounting structure and an opposite end of the coil spring means mounted on said hinge structure.

A door-hinge device comprising in combination:

• first and second spaced-apart hinge-support structures each mountable on an inwardly-facing surface of an upright door jamb-structure, a hinge structure having opposite first and second hinge-ends mounted on the first and second hinge-support structures, a first hinge-mounting means pivotably mounting the first hinge-end on the first hinge-support structure, a second hinge-mounting means pivotably mounting the second hinge-end on the second hinge-support structure, said first hinge-mounting means including one of a pivot pin and an elongated slot-forming structure and an elongated slot-space thereof, and the first hinge-support structure including the remaining one of the pin and the elongated slot-forming structure, said slot-space extending in a direction substantially transversely to a longitudinal axis of said hinge structure, said pivot pin being transversely-movably mounted in said slot-space, said one of said pivot pin and said elongated slot-forming structure being mounted as a part of said first end of the hinge structure, and said remaining one of said pivot pin and said elongated slot-forming structure being mounted as a part of said first support structure, and an abutting portion of at least one of said first hinge-mounting means and said first hinge-end including abutting means having spaced-apart surface portions positioned along a plane substantially parallel to a second axis extending between the first and second hinge-support structures and in juxtaposition thereto such that the abutting portion contacts and is movable-along a flat surface extending along said second axis when the hinge structure is revolvably pivoted.
