Abstract
A vertically adjustable hinge includes a first leaf rotatably connected to a leaf assembly. The leaf assembly defines an opening with at least a first inclined surface and includes a block received in the opening. The block defines a threaded hole and at least a second inclined surface abutting the first inclined surface. A leaf assembly housing receives the leaf assembly and the block. The leaf assembly housing defines screw holes for receiving a screw that passes through the threaded hole. A rotation of a screw in the threaded hole causes a horizontal translation of the block, which in turn causes a vertical translation of the leaf assembly.
Claims16
A hinge apparatus, comprising:
- a vertically adjustable hinge, comprising:
- a first leaf;
- a second leaf rotatably connected to the first leaf so the first and the second leafs are free to rotate relative to each other about a vertical axis;
- a first block defining a block opening with at least a first inclined surface;
- a second block received in the block opening, the second block defining at least a second inclined surface supporting the first inclined surface of the first block, the second block defining a threaded hole, wherein:
- the block opening comprises two walls defining inclined grooves;
- the second block comprises two walls with inclined tongues received in the inclined grooves of the block opening;
- a leaf housing receiving the second leaf, the first block, and the second block, the leaf housing having first and second vertical surfaces with vertical guides for the first block so the first block is vertically translatable relative to the leaf housing, the first vertical surface defining a first screw hole providing access to the threaded hole of the second block, the second vertical surface defining a second screw hole opposite the first screw hole;
- and
- a screw passing horizontally through the first screw hole of the leaf housing, the threaded hole of the second block, and the second screw hole of the leaf housing, wherein a rotation of the screw causes a horizontal translation of the second block relative to the leaf housing, which in turn causes a vertical translation of the first block, the second leaf, and the first leaf relative to the leaf housing.

A hinge apparatus, comprising:
- a vertically adjustable hinge, comprising:
- a first leaf;
- a second leaf rotatably connected to the first leaf so the first and the second leafs are free to rotate relative to each other about a vertical axis;
- a first block defining a block opening with at least a first inclined surface;
- a second block received in the block opening, the second block defining at least a second inclined surface supporting the first inclined surface of the first block, the second block defining a first threaded hole;
- a leaf housing receiving the second leaf, the first block, and the second block, the leaf housing having first and second vertical surfaces with vertical guides for the first block so the first block is vertically translatable relative to the leaf housing, the first vertical surface defining a first screw hole providing access to the first threaded hole of the second block, the second vertical surface defining a second screw hole opposite the first screw hole;
- a screw passing horizontally through the first screw hole of the leaf housing, the first threaded hole of the second block, and the second screw hole of the leaf housing, wherein a rotation of the screw causes a horizontal translation of the second block relative to the leaf housing, which in turn causes a vertical translation of the first block, the second leaf, and the first leaf relative to the leaf housing;
- a hex key;
- and
- a hinge pin with a circumferential groove, wherein the first and second leafs comprise knuckles, one of the knuckles defines a second threaded hole, the hinge pin is inserted through the knuckles, and the hex key is screwed through the second threaded hole and into the circumferential groove.

- and
- a screw passing horizontally through the first screw hole of the leaf housing, the threaded hole of the second block, and the second screw hole of the leaf housing, wherein a rotation of the screw causes a horizontal translation of the second block relative to the leaf housing, which in turn causes a vertical translation of the first block, the second leaf, and the first leaf relative to the leaf housing;
- and
- a horizontally adjustable hinge, comprising:
- a third leaf;
- a fourth leaf rotatably connected to the third leaf so the third and the fourth leafs are free to rotate relative to each other, the second leaf defining an other threaded hole;
- an other screw screwed through the other threaded hole;
- and
- an other leaf housing receiving the fourth leaf and the other screw, the other leaf housing having third and fourth vertical surfaces with other vertical guides receiving first and second ends of the other screw so the other screw is free to translate vertically relative to the leaf housing, wherein a rotation of the other screw causes a horizontal translation of the fourth and the third leafs relative to the leaf housing.

A vertical adjustable hinge, comprising:
- a first leaf;
- and
- a leaf assembly rotatably connected to the leaf, the leaf assembly comprising:
- a ramp;
- a block on the ramp, wherein one of the ramp and the block is only horizontally translatable and the other one is only vertically translatable and coupled to the leaf;
- a screw threaded horizontally through the one of the ramp and the block;
- a housing receiving the ramp, the block, and the screw, wherein a rotation of the screw causes a horizontal translation of the one of the ramp and the block relative to the housing, which in turn causes a vertical translation of the other of the ramp and the block and the first leaf relative to the housing;
- and
- a second leaf rotatably connected to the first leaf so the first and the second leafs are free to rotate relative to each other, the second leaf defining a leaf opening receiving the block, the second leaf being free to translate horizontally relative to the block;
