Abstract

An oven door hinge having an arm and a hinge assembly pivotally attached thereto. The hinge assembly has an elongated, channel-shaped housing that is configured to be removably and constrainingly received within a pocket of an oven door. The housing has two ends, with one end having a slotted, transverse end wall and the other end pivotally attached to the arm of the hinge at a first location. The hinge assembly also includes an elongated, channel-shaped link having two ends, with one end pivotally attached to the arm of the hinge at a second location, and the second end extending towards the transverse end wall of the housing. The link is configured to be retained within the channel of the housing so that it is able to shift positions with respect thereto as the hinge assembly is rotated. An elongated channel-shaped post having two ends is operatively connected to the other end of the link near the transverse end wall of the housing so that it extends through and beyond the transverse end wall of the housing, where it receives a spring element. An adjustment member that is attached to the other end of the post retains a spring element on the post. The adjustment member is provided with a threaded end and an adjustable stop to enable the length of the spring continuously varied within a predetermined range of values.

Claims

1. A hinge assembly for pivotally attaching an oven door to an oven of a range, the hinge assembly comprising:

a housing comprising a first end, a second end, opposing side walls and a transverse end wall, the first end of the housing pivotally attachable to a support arm at a first predetermined location;

a link comprising a first end, as second end, and opposing sidewalls, with the first end of the link pivotally attachable to the support arm at a second predetermined location, and with the link in substantial alignment with the housing;

a post comprising a first end, a second end, and opposing side walls, with the first end of the post operatively connectable to the second end of the link, wherein the second end of the post projects through the transverse end wall of the housing, the post in substantial alignment with the link;

an adjustment member operatively connected to the post, the adjustment member having an adjustable stop; and

a biasing element interposed between the end wall of the housing and the adjustable stop;

wherein the biasing element exerts a force that urges the hinge assembly towards a vertical position; and

,

wherein the force exerted by the biasing element may be changed by manipulating the adjustable stop.

2. The hinge of claim 1, wherein the link substantially nests within the housing.

3. The hinge assembly of claim 1, wherein the adjustable stop is stepless.

4. The hinge assembly of claim 1, wherein the adjustment member comprises a threaded shaft, and wherein the adjustable stop comprises a threaded fastener.

5. The hinge of claim 1, wherein the biasing element is a spring.

6. A hinge for pivotally attaching an oven door to an oven of a range, the hinge comprising:

an arm, the arm connectable to a range; and

a hinge assembly, the hinge assembly attachable to the arm and connectable to an oven door, the hinge assembly comprising;

a generally u-shaped housing comprising a first end, a second end, opposing side walls and a transverse end wall, the first end of the u-shaped housing pivotally attachable to the arm at a first predetermined location;

a generally u-shaped link comprising a first end, a second end, and opposing sidewalls, with the first end of the u-shaped link pivotally attachable to the arm at a second predetermined location, and with the u-shaped link nestably positionable with respect to the u-shaped housing;

a generally u-shaped post comprising a first end, a second end, and opposing side walls, with the first end of the u-shaped post operatively connectable to the second end of the u-shaped link, wherein the second end of the u-shaped post projects through the transverse end wall of the u-shaped housing;

an adjustment member operatively connected to the second end of the u-shaped post, the adjustment member comprising an adjustable stop; and

a biasing element interposed between the transverse end wall of the u-shaped housing and the adjustable stop;

wherein the biasing element exerts a force that urges the hinge assembly towards a vertical position; and

wherein the force exerted by the biasing element may be changed by manipulating the adjustable stop.

7. The hinge of claim 6, wherein the adjustable stop is stepless.

8. The hinge of claim 6, wherein the adjustment member comprises a threaded shaft, and wherein the adjustable stop comprises a threaded fastener.

9. The hinge of claim 6, wherein the biasing element is a spring.
