A hinge assembly for mounting a door on a cabinet below an opening thereof is provided. The hinge assembly may include a pin defining an axis about which the door rotates, the pin being supported by a hinge plate and including a splined portion. Moreover, the hinge assembly may include a height adjuster including an inner circumference through which the pin extends and at least a portion that is rotatable about the pin. The hinge assembly additionally may include a first cam element including a cam surface and an inner circumference through which the pin extends, the inner circumference corresponding to the splined portion of the pin for mating therewith at a single position, the first cam element being vertically adjustable along the splined portion of the pin through rotation of the rotatable portion of the height adjuster about the pin.

1. A hinge assembly for mounting a door on a cabinet below an opening thereof, the hinge assembly comprising: a hinge plate configured to mount the door to the cabinet, the hinge plate comprising a hole extending through the hinge plate;a pin configured to define an axis about which the door rotates
1. A hinge assembly for mounting a door on a cabinet below an opening thereof, the hinge assembly comprising: a hinge plate configured to mount the door to the cabinet, the hinge plate comprising a hole extending through the hinge plate;a pin configured to define an axis about which the door rotates, the pin being supported by the hinge plate and comprising a bush, a splined portion, a threaded portion, and a cylindrical portion, the bush and the cylindrical portion being positioned at opposite ends of the pin, the threaded portion being positioned between the bush and the splined portion, the splined portion being positioned between the threaded portion and the cylindrical portion, the bush extending into the hole in the hinge plate, the bush engaging walls of the hole in the hinge plate to limit rotation of the pin;a height adjuster comprising a threaded hole threaded onto the threaded portion of the pin and a knurled surface on a side of the height adjuster that faces away from the hinge plate;a first cam element comprising a splined hole through which the splined portion of the pin extends, the splined hole engaging the splined portion of the pin to inhibit rotation of the first cam element, a cam surface facing away from the height adjuster, and a knurled surface engaging the knurled surface of the height adjuster to inhibit rotation of the height adjuster about the pin; anda mounting plate comprising a second cam element interacting with the first cam element, the second cam element comprising a cylindrical hole through which the cylindrical portion of the pin extends and a cam surface interacting with the cam surface of the first cam element, the cylindrical hole comprising an projection into which the cylindrical portion of the pin is positioned and a diameter that is greater than an outerdiameter of the splined portion of the pin, the engagement of the cam surfaces of the first and second cam elements being configured to control a position and an action of the door, the projection being rotatable about the pin and configured to fit into a hole in the door and rotate about the pin with the mounting plate,wherein the height adjuster is configured to move vertically on the pin when rotated about the pin thereby adjusting the height of the door. 2. The hinge assembly of claim 1, further comprising: a limiting plate fastened to the mounting plate and surrounding the second cam element and the pin, the limiting plate being configured to rotate about the pin with the door, the limiting plate comprising a tab,wherein the hinge plate comprises a stopper, the stopper being configured to inhibit the door from rotating past a predetermined position, andwherein the predetermined position is defined by a position at which the tab contacts the stopper. 3. The hinge assembly of claim 1, wherein the cam surface of the first cam element comprises elevated portions, depressed portions, and transitional portions connecting the elevated portions and the depressed portions. 4. The hinge assembly of claim 3, wherein the cam surface of the second cam element comprises elevated portions, depressed portions, and transitioning portions connecting the elevated portions and the depressed portions, and wherein the elevated portions, the depressed portions, and the transitioning portions of the second cam element interact with the elevated portions, the depressed portions, and the transitioning portions of the first cam element. 5. The hinge assembly of claim 4, wherein the elevated portions of the cam surface of the first cam element divide a circumference of the cam surface of the first cam element into a plurality of arced zones between which the elevated portions of the cam surface of the second cam element are configured to move in order to control the position and the action of the door. 6. The hinge assembly of claim 1, wherein, when an angular range defined by the position of the door and a point at which the door meets the opening of the cabinet is 0 to 20 degrees, the cam surface of the second cam element is configured to interact with the cam surface of the first cam element to urge the door to the point at which the door meets the opening of the cabinet. 7. The hinge assembly of claim 1, wherein, when an angular range defined by the position of the door and a point at which the door meets the opening of the cabinet is 125 degrees or greater, the cam surface of the second cam element is configured to interact with the cam surface of the first cam element to maintain the angular range. 8. The hinge assembly of claim 1, wherein the hinge plate comprises slots configured to allow mounting of the hinge plate on the cabinet below the opening thereof to be adjustable perpendicular to the axis. 9. The hinge assembly of claim 1, wherein the hole of the hinge plate comprises a rectangular hole, and wherein the bush of the pin comprises a rectangular bush projecting from the pin and mating with the rectangular hole. 10. The hinge assembly of claim 1, wherein the projection is cylindrical to facilitate the rotation of the door about the axis. 11. The hinge assembly of claim 1, wherein the splined portion of the pin comprises a plurality of splines extending from the threaded portion to the cylindrical portion of the pin, each of the splines protruding perpendicular to the axis away from a center of the pin and further from the center of the pin than an outer circumference of the cylindrical portion. 12. The hinge assembly of claim 1, wherein the height adjuster further comprises a plurality of outer knurled surfaces positioned on an outer circumference of the height adjuster, and wherein the outer knurled surfaces are configured to enable grabbing of the forcibly mated height adjuster to enable forcible rotation of the threaded hole about the pin. 13. The hinge assembly of claim 1, wherein the protrusion is integrally formed in the mounting plate.
