Abstract

A door hinge assembly is provided which includes a mounting body with a pocket for receiving an edge of a door, a clamping mechanism positioned on and securing the mounting body to the door, a pin projecting upwards from the mounting body and a bushing for receiving the pin. The bushing is mounted in a recess of a door frame and preferably includes a series of fluted ribs along its outer wall. An annular ring projects inwardly from an inner wall of the bushing. A channel on the pin receives the annular ring and retains same within the bushing.

Claims

1. A door hinge assembly comprising:

a mounting body having walls forming an opening for receiving an edge of a door;

at least one clamping means positioned on one of the walls of the mounting body for securing the door to the body;

a pin with upper and lower ends, the pin being connected at the lower end to the mounting body, the pin including a pin head at the upper end, and a uniformly diametered trunk being adjacent the lower end and a uniformly, reduced diametered neck forming annular channel between the pin head and the trunk; and

a bushing with outer and inner walls, the outer wall including means for engaging a recess in a doors frame, the inner wall defining a cylindrical cavity for receiving the pin and including an annular ring projecting inward from the inner wall for snap seating of the annular ring within the annular channel, the annular channel having an axial length substantially greater than a axial length of the annular ring permitting the pin an amount of vertical play for adjustment.

2. The door hinge assembly according the claim 1 wherein the means for engaging the recess comprises a plurality of vertically oriented ribs.

3. The door hinge assembly according to claim 1 wherein the clamping means is a screw comprising a head with at least two flat sides parallel one another.

4. The door hinge assembly according to claim 3 wherein the head is formed with a pair of cross slots.

5. The door hinge assembly according to claim 1 wherein the clamping means is a screw formed of pressed fibers molded together.

6. The door hinge assembly according to claim 1 wherein the mounting body further comprises an end wall orthogonal to a pair of parallel side walls forming the opening.
