Adjustable hinge
View Patent ↗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.
1. An 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;
a hinge arm pivotally connected to the hinge cup and integrally formed with an attachment section;
a deformable hinge member comprised of a semi-cylindrical plate integrally formed with the attachment section and an abutment section;
a first set of alignment tabs, extending from the abutment section for contact with the cabinet frame and for alignment of the abutment section with the cabinet frame;
a second set of alignment tabs, opposing the first set of alignment tabs, extending from the abutment section for contact with the cabinet frame and for alignment of the abutment section with the cabinet frame;
a raised seat extending from the abutment section towards the attachment section;
an overlay adjustment screw, detachable from the abutment section, for threaded insertion through the attachment section and abutting the seat; and,
wherein the overlay adjustment screw moves the attachment section with respect to the abutment section by bending the deformable hinge member in order to effect an overlay adjustment.
2. The adjustable hinge fixture of claim 1 further comprising:
a pivot axis defined by the pivotable connection between the hinge arm and the hinge cup;
a bending axis defined by the semi-cylindrical plate; and,
where the pivot axis is generally parallel to the bending axis.
3. An adjustable hinge for mounting a door member on a cabinet frame comprising:
a hinge cup pivotally connected to a hinge arm;
the hinge arm comprising a first plate connected to a second plate by a deformable hinge plate;
wherein the hinge arm is of one-piece construction including the first plate, the deformable hinge plate, and the second plate;
wherein the hinge arm further includes a first set of guide flanges connected to the second plate located adjacent to the deformable hinge plate for contact with the cabinet frame and a second set of guide flanges connected to the second plate located opposite the deformable hinge plate for contact with the cabinet frame;
wherein a raised platform extends from the second plate towards the first plate;
wherein an overlay adjustment screw is detachable from the second plate and threadably engaged with the first plate abuts the platform; and,
wherein rotation of the overlay adjustment screw alters the location of the first plate relative to the second plate by bending the deformable hinge plate.
4. The adjustable hinge of claim 3 wherein the hinge arm is pivotally connected to the hinge cup via a pin having a pivoting axis and wherein the deformable hinge plate has a bending axis generally parallel to the pivoting axis.
5. The adjustable hinge of claim 3 wherein the first plate has an access hole and the second plate has a vertical adjustment slot axially aligned with the access hole, wherein a vertical adjustment screw attaches the second plate to the cabinet frame and the access hole provides access to the vertical adjustment screw.
