Hinge assembly for mounting door on cabinet below opening thereof

摘要

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, 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; and a 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 outer diameter 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.
