Abstract

The invention disclosed provides a hinge capable of a vertical and overlay adjustment, comprised of a recessed hinge cup and a hinge arm connected to an attachment plate and an abutment plate which are further connected by a deformable hinge section. An overlay adjustment is provided by bending the deformable hinge section through use of an overlay adjustment screw fitted between the attachment plate and the abutment plate. The novel hinge provided is also adjustable vertically via an adjustment screw accessed by a portal in the attachment plate. The design is less complicated and therefore is lighter and less expensive than previous overlay adjustable hinges and allows delicate and semi-permanent adjustments to be made by a single installer.

Claims

1. An adjustable hinge for mounting a cabinet door having a receiving bore to a cabinet frame comprising:

a hinge cup adapted to reside in the receiving bore;

a pair of mounting flanges attached to the hinge cup for attaching the hinge cup to the cabinet door;

a spring retaining tab on the hinge cup;

a pair of coaxially aligned spring retaining holes in the hinge cup;

a pair of coaxially aligned hinge arm mounting holes in the hinge cup;

a hinge arm having a tubular mounting hole and further comprising a first cam surface and a second cam surface;

the hinge arm rotatably mounted in the hinge cup by an axle pin having a first axis through the hinge arm mounting holes and the tubular mounting hole;

a coiled bias spring having a pair of helical coils and a first end and a second end adjacent the helical coils and a connecting arch between the helical coils;

the coiled bias spring further attached to the hinge cup whereby the connecting arch is adjacent the spring retaining tab, the pair of helical coils is coaxially aligned with the pair of hinge mounting holes and retained by a retaining pin through the retaining holes, and the first end is in sliding contact with the first cam surface and the second end is in sliding contact with the second cam surface;

an adjustment plate rigidly attached to the hinge arm and having an access hole and a threaded overlay adjustment hole;

an abutment plate having an elongated cabinet frame mounting hole for adjustably attaching the abutment plate to the cabinet frame;

a rigidly deformable unitary hinge plate connecting the adjustment plate and the abutment plate whereby the access hole is adjacent the elongated cabinet frame mounting hole;

a first set of guide flanges extending from the abutment plate at approximately 50 degrees adjacent to and flanking opposite edges of the rigidly deformable unitary hinge plate for contact with the cabinet frame;

a second set of guide flanges extending generally perpendicularly from the abutment plate for contact with the cabinet frame wherein the first set of guide flanges and the second set of guide flanges cooperate to center the abutment plate on the cabinet frame;

wherein the hinge arm is of one-piece construction including the adjustment plate, the abutment plate, and the rigidly deformable unitary hinge plate; and

a threaded adjustment means, mounted in the threaded overlay adjustment hole and in contact with the abutment plate whereby when the threaded adjustment means is rotated the adjustment plate is angularly displaced with respect to the abutment plate by plastic deformation of the rigidly deformable unitary hinge plate.

2. The adjustable hinge of claim 1 wherein the threaded adjustment means further comprises a threaded screw rotatably attached to a seating means on the abutment plate for advancement and retraction of the adjustment plate.

3. The adjustable hinge of claim 2 wherein the seating means further comprises:

a raised seat platform on the abutment plate having a seating hole therethrough; and

,

a retaining means adjacent the seating hole and rigidly attached to the threaded adjustment means.

4. The adjustable hinge of claim 3 wherein the retaining means further comprises an extension shaft on the adjustment means extending through the seating hole and terminating in a mushroom cap of diameter larger than the hole.

5. The adjustable hinge of claim 3 wherein the retaining means further comprises a cavity adjacent the seating hole and a keeper surface on the threaded adjustment means of larger diameter than the seating hole.

6. The adjustable hinge of claim 1 wherein the rigidly deformable unitary hinge plate has a bending axis that is generally parallel to the first axis.
