Abstract

A hinge system for mounting a door to an appliance has an upper hinge bracket having an upper hinge swing element configured to engage a door upper swing element fixed to the door, the engagement of the upper hinge swing element and the door upper swing element allowing the door to swing about a vertical axis between an open position and a closed position, and an upper hinge pivot limiting element configured to engage a frame pivot limiting element fixed to the appliance; a lower hinge bracket having a lower hinge swing element configured to engage a door lower swing element, and a system pivot element configured to engage a frame pivot element such that the upper hinge bracket, the lower hinge bracket, and the door are pivotable about a horizontal axis as a unit relative to the appliance while still being attached to the appliance.

First claim

What is claimed is:

1. A hinge system for mounting a side swing door of a domestic kitchen appliance to a frame of the domestic kitchen appliance, the system comprising:
an upper hinge bracket having
an upper hinge swing element configured to engage a door upper swing element fixed to the door of the domestic kitchen appliance, the engagement of the upper hinge swing element and the door upper swing element allowing the door to swing about a vertical axis between an open position and a closed position, and
an upper hinge pivot limiting element configured to engage a frame pivot limiting element fixed to the frame of the domestic home appliance;

a lower hinge bracket having
a lower hinge swing element configured to engage a door lower swing element, the engagement of the lower hinge swing element and the door lower swing element allowing the door to swing about the vertical axis between the open position and the closed position, and
a system pivot element configured to engage a frame pivot element such that the upper hinge bracket, the lower hinge bracket, and the door are pivotable about a horizontal axis as a unit relative to the frame of the domestic kitchen appliance between an appliance operational position and a door removal position; and

an operational position holding element attached to the upper hinge bracket or the lower hinge bracket, the operational position holding element configured to releasably hold the door in the appliance operational position,
wherein the appliance operational position is a position of the upper hinge bracket, the lower hinge bracket, and the door at which the domestic kitchen appliance can be operated, and
the upper hinge bracket and the lower hinge bracket are configured to keep the door attached to the frame of the domestic kitchen appliance when the upper hinge bracket, the lower hinge bracket and the door are in the door removal position.

2. The system of claim 1 , wherein the upper hinge swing element is a hole and the door upper swing element is a pin.

3. The system of claim 2 , wherein the lower hinge swing element is a hole or a recess and the door lower swing element is a pin.

4. The system of claim 1 , wherein the lower hinge swing element is a pin and the door lower swing element is a hole or recess.

5. The system of claim 1 , wherein the upper hinge pivot limiting element is a slot and the frame pivot limiting element is a bolt.

6. The system of claim 5 , wherein the slot is a radiused slot having a constant radius relative to the horizontal axis.

7. The system of claim 5 , wherein the slot is closed at a pivot limiting end and configured to hold the door in the door removal position by the frame pivot limiting element contacting the pivot limiting end of the slot.

8. The system of claim 1 , wherein the system pivot element is a hole and the frame pivot element is a bolt.

9. The system of claim 1 , wherein the operational position holding element is a tab, the tab having a hole configured to receive a fastener that holds the tab in a fixed position relative to the frame of the domestic kitchen appliance when the door is in the operational position.

10. The system of claim 1 , wherein the upper hinge bracket further comprises a second upper hinge pivot limiting element configured to engage a second frame pivot limiting element fixed to the frame of the domestic home appliance.

11. The system of claim 1 , wherein the upper hinge bracket and the lower hinge bracket are configured to be attached to the frame of the domestic kitchen appliance when the upper hinge bracket, the lower hinge bracket and the door are in the door removal position, such that the door is held in the door removal position by the upper hinge bracket and the lower hinge bracket.

12. A domestic kitchen appliance having a cavity for receiving food to be processed by the domestic kitchen appliance, the domestic kitchen appliance comprising:
a frame having a frame pivot limiting element and a frame pivot element;
a side swing door for selectively opening or closing the cavity, the door having a door upper swing element and a door lower swing element;
a hinge system mounting the door to the frame of the domestic kitchen appliance, the hinge system having
an upper hinge bracket having
an upper hinge swing element engaging the door upper swing element, the engagement of the upper hinge swing element and the door upper swing element allowing the door to swing about a vertical axis between an open position and a closed position, and
an upper hinge pivot limiting element engaging the frame pivot limiting element;

a lower hinge bracket having
a lower hinge swing element engaging the door lower swing element, the engagement of the lower hinge swing element and the door lower swing element allowing the door to swing about the vertical axis between the open position and the closed position, and
a system pivot element engaging the frame pivot element such that the upper hinge bracket, the lower hinge bracket, and the door are pivotable about a horizontal axis as a unit relative to the frame of the domestic kitchen appliance between an appliance operational position and a door removal position; and

an operational position holding element attached to the upper hinge bracket or the lower hinge bracket, the operational position holding element releasably holding the door in the appliance operational position,
wherein the appliance operational position is a position of the upper hinge bracket, the lower hinge bracket, and the door at which the domestic kitchen appliance can be operated, and
the upper hinge bracket and the lower hinge bracket keep the door attached to the frame of the domestic kitchen appliance when the upper hinge bracket, the lower hinge bracket and the door are in the door removal position.

13. The domestic kitchen appliance of claim 12 , wherein the upper hinge swing element is a hole and the door upper swing element is a pin.

14. The domestic kitchen appliance of claim 13 , wherein the pin is removable from the door such that removing the pin from the door allows the door to move relative to the upper hinge swing element.

15. The domestic kitchen appliance of claim 13 , wherein the lower hinge swing element is a hole or a recess and the door lower swing element is a pin.

16. The domestic kitchen appliance of claim 12 , wherein the upper hinge pivot limiting element is a slot and the frame pivot limiting element is a bolt.

17. The domestic kitchen appliance of claim 16 , wherein the slot is a radiused slot having a constant radius relative to the horizontal axis.

18. The domestic kitchen appliance of claim 16 , wherein the slot is closed at a pivot limiting end and configured to hold the door in the door removal position by the frame pivot limiting element contacting the pivot limiting end of the slot.

19. The domestic kitchen appliance of claim 12 , wherein the system pivot element is a hole and the frame pivot element is a bolt.

20. The domestic kitchen appliance of claim 12 , wherein the operational position holding element is a tab, the tab having a hole configured to receive a fastener that holds the tab in a fixed position relative to the frame of the domestic kitchen appliance when the door is in the operational position.

21. The domestic kitchen appliance of claim 12 , wherein the upper hinge bracket further comprises a second upper hinge pivot limiting element configured to engage a second frame pivot limiting element fixed to the frame of the domestic
