Abstract

According to one embodiment, an oven includes an oven chamber operable to be heated and having a front opening. The oven further includes a frame coupled to and at least partially surrounding the oven chamber. The oven further includes a door operable to seal the front opening of the oven chamber, and a pair of hinges pivotally coupling the door to the frame. Each hinge is positioned on opposing sides of the oven chamber. The oven further includes a pair counterweights that are each coupled to the rear portion of a respective hinge, and a pair of dampers. Each damper is coupled to the frame and operable to resist movement of the door in a single direction opposite that of the other damper.

First claim

What is claimed is:

1. An oven, comprising:
a. an oven chamber operable to be heated, the oven chamber having a front opening;
b. a frame coupled to and at least partially surrounding the oven chamber, the frame including a pair of vertical portions each being positioned on opposing lateral sides of the front opening;
c. a door operable to seal the front opening of the oven chamber, the door extending laterally to at least the vertical portions of the frame;
d. a pair of hinges pivotally coupling the door to the frame, the hinges each being positioned on opposing sides of the oven chamber, each hinge having:
i. a front portion disposed in-between a front surface and a back surface of the door; and
ii. a rear portion that extends rearward away from the door and through an opening in a respective vertical portion of the frame;

e. a pair of counterweights that are each coupled to the rear portion of a respective hinge, wherein the rear portion of each of the hinges and each of the counterweights are configured to pivot when the door pivots; and
f. a pair of dampers, each damper coupled to the frame and operable to resist movement of the door in a single direction opposite that of the other damper, wherein a first damper of the pair of dampers couples a first counterweight of the pair of counterweights to the frame.

2. The oven of claim 1 , wherein the oven chamber is selected from a group consisting of:
a. a gas oven chamber;
b. an electric oven chamber;
c. a wood-burning oven chamber;
d. a charcoal-burning oven chamber; and
e. a convection oven chamber.

3. The oven of claim 1 , wherein the first damper of the pair of dampers is an extension damper.

4. The oven of claim 1 , wherein a second damper of the pair of dampers is a compression damper.

5. The oven of claim 1 , further comprising a second pair of dampers, each damper of the second pair of dampers being coupled to the frame and operable to resist movement of the door in a single direction opposite that of the other damper of the second pair of dampers, a first damper of the second pair of dampers coupling a second counterweight of the pair of counterweights to the frame.

6. The oven of claim 1 , wherein each damper of the pair of dampers is positioned on the same side of the oven chamber.

7. The oven of claim 1 , wherein each damper of the pair of dampers is positioned on opposing sides of the oven chamber.

8. The oven of claim 1 , wherein the pair of counterweights have a combined weight that is equal to a weight of the door plus or minus 5 pounds.

9. The oven of claim 1 , wherein the front portion of each hinge is positioned orthogonal to the rear portion.

10. A method, comprising:
a. coupling a frame to an oven chamber so that the frame at least partially surrounds the oven chamber, the oven chamber being operable to be heated, the oven chamber having a front opening, the frame having a pair of vertical portions that are each positioned on opposing lateral sides of the front opening;
b. pivotally coupling a door to the frame using a pair of hinges, the door being operable to seal the front opening of the oven chamber, the door extending laterally to at least the vertical portions of the frame, the hinges each being positioned on opposing sides of the oven chamber, each hinge having:
i. a front portion disposed in-between a front surface and a back surface of the door; and
ii. a rear portion that extends rearward away from the door and through an opening in a respective vertical portion of the frame;

c. coupling each of a pair of counterweights to the rear portion of a respective hinge wherein the rear portion of each of the hinges and each of the counterweights are configured to pivot when the door pivots;
d. coupling a pair of dampers to the frame, each damper being operable to resist movement of the door in a single direction opposite that of the other damper; and
e. coupling a first counterweight of the pair of counterweights to the frame using a first damper of the pair of dampers.

11. The method of claim 10 , wherein the oven chamber is selected from a group consisting of:
a. a gas oven chamber;
b. an electric oven chamber;
c. a wood-burning oven chamber;
d. a charcoal-burning oven chamber; and
e. a convection oven chamber.

12. The method of claim 10 , wherein the first damper of the pair of dampers is an extension damper.

13. The method of claim 10 , wherein a second damper of the pair of dampers is a compression damper.

14. The method of claim 10 , further comprising:
a. coupling a second pair of dampers to the frame, each damper of the second pair of dampers being operable to resist movement of the door in a single direction opposite that of the other damper of the second pair of dampers; and
b. coupling a second counterweight of the pair of counterweights to the frame using a first damper of the second pair of dampers.

15. The method of claim 10 , wherein each damper of the pair of dampers is positioned on the same side of the oven chamber.

16. The method of claim 10 , wherein each damper of the pair of dampers is positioned on opposing sides of the oven chamber.

17. The method of claim 10 , wherein the pair of counterweights have a combined weight that is equal to a weight of the door plus or minus 5 pounds.

18. An oven, comprising:
a. an oven chamber operable to be heated, the oven chamber having a front opening;
b. a frame operatively coupled to support and at least partially surround the oven chamber;
c. a door operable to seal the front opening of the oven chamber, the door extending laterally to at least a pair of vertical portions of the frame;
d. a pair of hinges pivotally coupling the door to the frame, the hinges each being positioned on opposing sides of the oven chamber and in-between respective side portions of the frame and the oven chamber, each hinge having:
i. a front portion disposed in-between a front surface and a back surface of the door; and
ii. a rear portion that extends rearward away from the door and through an opening in a respective vertical portion of the frame;

e. a first counterweight coupled to the rear portion of a first hinge of the pair of hinges wherein both the rear portion of the first hinge and the first counterweight are configured to pivot when the door pivots; and
f. a first damper coupled to the frame and operable to resist movement of the door in at least a first direction, wherein the first damper couples the first counterweight to the frame.

19. The oven of claim 18 , further comprising a second counterweight coupled to the rear portion of a second hinge of the pair of hinges.

20. The oven of claim 18 , further comprising a second damper coupled to the frame and operable to resist movement of the door in a direction opposite of that resisted by the first damper.

21. The oven of claim 20 , wherein the first damper and the second damper are each disposed in-between a side portion of the frame and the oven chamber.

22. The oven of claim 21 , wherein the first damper is an extension damper pivotally coupled to a portion of the frame and a portion of at least one of the first counterweight and the rear portion of the first hinge of the pair of hinges, and wherein the second damper is a compression damper.

23. The oven of claim 22 , wherein the extension damper and compression damper are disposed on the same side of the oven chamber.

24. The oven of claim 18 , wherein the first da
