Adjustable hinge
First Claim
1. An overlay adjustable hinge fixture for mounting a door member on a cabinet frame member comprising:
- a hinge cup fitted for insertion into a bore of the door member having a spring support tab, a first pair of concentrically aligned support holes and a second pair of concentrically aligned support holes;
a hinge arm having a tubular slot pivotally connected to the hinge cup by a first axel pin through the tubular slot and the first pair of concentrically aligned support holes;
the hinge arm connected to an attachment section;
a deformable hinge member comprised of a semi-cylindrical plate attached along a first longitudinal axis to the attachment section and attached along a second longitudinal axis to an abutment section;
a spring functionally held adjacent the hinge cup by a second axel pin through the second pair of concentrically aligned support holes;
the tubular slot further forming at least one cam surface adjacent the spring whereby the spring biases the hinge arm against the hinge cup in at least one of an open position and a closed position;
wherein the abutment section includes an elongated aperture longitudinally aligned with the axis of rotation of the tubular slot;
a vertical adjustment screw for threaded insertion into the cabinet frame through the elongated aperture;
a first pair of alignment tabs, connected to the abutment section for alignment of the abutment section with the cabinet frame;
a second pair of alignment tabs, opposing the first pair of alignment tabs, connected to the abutment section for alignment of the abutment section with the cabinet frame;
the abutment section further comprising a raised platform defining a centering hole;
wherein the attachment section is further comprised of an access aperture adjacent the elongated aperture and an adjustment hole;
an overlay adjustment screw for threaded insertion through the adjustment hole and abutting the centering hole;
wherein the overlay adjustment screw may be rotated to move the attachment section with respect to the abutment section by bending the deformable hinge member in order to effect an overlay adjustment; and
,wherein the vertical adjustment screw may be accessed through the access aperture and rotated to allow a vertical adjustment of the abutment section with respect to the cabinet frame member.

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.

5. An adjustable hinge comprising:
-
a hinge cup pivotally connected to a hinge arm; the hinge arm including a first plate having a rectangular access aperture and an overlay adjustment screw in a threaded adjustment hole; the first plate connected to a second plate by a deformable hinge plate;
wherein the second plate further comprises an elongated hole generally aligned with the rectangular access aperture and including a receiving surface adjacent the adjustment screw;wherein the overlay adjustment screw abuts the receiving surface;
where the overlay adjustment screw advances when turned thereby altering the location of the first plate relative to the second plate by bending the deformable hinge plate; and
,wherein access to a vertical adjustment screw in the elongated hole is provided by the rectangular access aperture. - View Dependent Claims (6, 7)

8. 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 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 and a plurality of guide flanges for centering the adjustment plate on 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 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 attachment plate is angularly displaced with respect to the abutment plate by plastic deformation of the rigidly deformable unitary hinge plate. - View Dependent Claims (9, 10, 11, 12, 13)
