Abstract

A hinge construction includes a hinge bracket that includes a hinge pin supporting plate and at least one opening extending through the hinge pin supporting plate. Also included in the hinge construction is a hinge pin that is held at the at least one opening. The hinge pin includes a hinge pin outer surface, a hinge pin bore extending through the entire length of the hinge pin and a hinge pin slot extending along the entire length of the hinge pin from the hinge pin outer surface to within the hinge pin bore. The at least one opening can be tapered, and the hinge pin outer surface can include a hinge pin outer surface first portion that also is tapered so as to be congruent with the at least one tapered opening. The hinge construction allows elements such as electrical wiring to be routed through the hinge construction.

First claim

What is claimed is:

1. A hinge construction including:
a frame hinge bracket configured to be secured to a frame including a hinge pin supporting plate and a first and second frame bracket opening extending through the hinge pin supporting plate;
a hinge pin held within the first or second frame bracket opening, the hinge pin including:
a hinge pin outer surface; and
a hinge pin bore extending through the entire length of the hinge pin;

a door hinge bracket that is configured to be secured to a door, comprising a first and a second door bracket opening; and
a bearing system, comprising a first bearing having a first cam surface and a second bearing having a second cam surface that cooperates with the first cam surface during rotation of the door;
wherein the frame hinge bracket comprises an upturned portion, wherein the door hinge bracket comprises at least two protrusions, wherein the protrusions are configured to cooperate with the upturned portion to prohibit rotation of the door about a rotational axis defined by the hinge pin beyond respective certain positions in different rotational directions,
wherein in a first configuration the hinge pin is held within the first frame bracket opening and the hinge pin extends through the first door bracket opening,
wherein in a second configuration the hinge pin is held within the second frame bracket opening and the hinge pin extends through the second door bracket opening.

2. The hinge construction of claim 1 , wherein the frame hinge bracket further includes a third and a fourth frame bracket opening, extending through the hinge pin supporting plate.

3. The hinge construction of claim 2 , wherein in the first configuration a portion of the first bearing is operably held at the third frame bracket opening and in the second configuration a portion of the first bearing is operably held at the fourth frame bracket opening.

4. The hinge construction of claim 1 , wherein in the first configuration the first protrusion is configured to cooperate with the upturned portion to prohibit rotation of the door beyond a first position in a first rotational direction about the rotational axis and in the second configuration the second protrusion is configured to cooperate with the upturned portion to prohibit rotation of the door beyond a second position in a second rotational direction about the rotational axis.

5. A hinge construction including:
a frame hinge bracket configured to be secured to a frame including a hinge pin supporting plate and a first and second frame bracket tapered opening extending through the hinge pin supporting plate;
a hinge pin including:
a hinge pin outer surface, including a hinge pin outer surface first portion that is tapered along a length of the hinge pin so as to be congruent with the first and second frame bracket tapered openings extending through the hinge pin supporting plate, the hinge pin being held within the first or second tapered opening at the hinge pin outer surface first portion; and
a hinge pin bore extending through the entire length of the hinge pin;

a door hinge bracket that is configured to be secured to a door, comprising a first and a second door bracket opening; and
a bearing system, comprising a first bearing having a first cam surface and a second bearing having a second cam surface that cooperates with the first cam surface during rotation of the door;
wherein the frame hinge bracket comprises an upturned portion, wherein the door hinge bracket comprises at least two protrusions, wherein the protrusions are configured to cooperate with the upturned portion to prohibit rotation of the door about a rotational axis defined by the hinge pin beyond respective certain positions in different rotational directions,
wherein in a first configuration the hinge pin is held within the first frame bracket tapered opening and the hinge pin extends through the first door bracket opening,
wherein in a second configuration the hinge pin is held within the second frame bracket tapered opening and the hinge pin extends through the second door bracket opening.

6. The hinge construction of claim 5 wherein the first portion of the hinge pin is selectively held within one of the first and second frame bracket tapered openings.

7. The hinge construction of claim 6 wherein each of the first and second frame bracket tapered openings are entirely circumscribed by the hinge pin supporting plate.

8. The hinge construction of claim 7 wherein the outer surface of the hinge pin includes a hinge pin outer surface second portion that has a cylindrical configuration and merges with the hinge pin outer surface first portion.

9. The hinge construction of claim 5 wherein each of the first and second frame bracket tapered openings are entirely circumscribed by the hinge pin supporting plate.

10. The hinge construction of claim 9 wherein the door is part of a refrigeration appliance.

11. The hinge construction of claim 9 wherein the outer surface of the hinge pin includes a hinge pin outer surface second portion that has a cylindrical configuration and merges with the hinge pin outer surface first portion.

12. The hinge construction of claim 11 wherein the second portion of the hinge pin is rotatably held at the door.

13. The hinge construction of claim 5 wherein the outer surface of the hinge pin includes a hinge pin outer portion second portion that has a cylindrical configuration and merges with the hinge pin outer surface first portion.

14. The hinge construction of claim 5 , wherein the frame hinge bracket further includes a third and a fourth frame bracket opening, extending through the hinge pin supporting plate.

15. The hinge construction of claim 14 , wherein in the first configuration a portion of the first bearing is operably held at the third frame bracket opening and in the second configuration a portion of the first bearing is operably held at the fourth frame bracket opening.

16. The hinge construction of claim 5 , wherein in the first configuration the first protrusion is configured to cooperate with the upturned portion to prohibit rotation of the door beyond a first position in a first rotational direction about the rotational axis and in the second configuration the second protrusion is configured to cooperate with the upturned portion to prohibit rotation of the door beyond a second position in a second rotational direction about the rotational axis.

17. A hinge construction including:
a frame hinge bracket configured to be secured to a frame including a hinge pin supporting plate and a first, a second, a third, and a fourth frame bracket opening extending through the hinge pin supporting plate;
a hinge pin held within the first or second frame bracket opening, the hinge pin including:
a hinge pin outer surface; and
a hinge pin bore extending through the entire length of the hinge pin;

a door hinge bracket that is configured to be secured to a door, comprising a first and a second door bracket opening; and
a bearing system, comprising a first bearing having a first cam surface and a second bearing having a second cam surface that cooperates with the first cam surface during rotation of the door;
wherein the frame hinge bracket comprises an upturned portion, wherein the door hinge bracket comprises at least two protrusions, wherein the protrusions are configured to cooperate with the upturned portion to prohibit rotation of the door about a rotational axis defined by the hinge pin beyond respective certain positions in different rotational directions,
wherein in a first configu
