Abstract

A door assembly includes an inner door panel and an outer door panel pivotable with respect to the inner door panel, the inner door panel including a latch base. The outer door panel includes a handle assembly including a handle endcap, a handle body rotatable with respect to the handle endcap, and a latch bar connected with the handle body, the latch bar being detachably coupled to the latch base. The outer door panel is rotatable with respect to the inner door panel, such that the outer door panel can be rotated away from the inner door panel.

First claim

What is claimed is:

1. A door assembly defining a vertical direction, a lateral direction, and a transverse direction, the door assembly comprising:
an inner door panel;
a latch base fixed to the inner door panel;
an outer door panel pivotally connected to the inner door panel; and
a handle assembly attached to the outer door panel, wherein the handle assembly comprises:
a handle endcap attached to an outer surface of the outer door panel;
a handle body connected with the handle endcap, the handle body being rotatable with respect to the handle endcap; and
a latch bar extending from the handle body such that the latch bar rotates together with the handle body, the latch bar being detachably coupled to the latch base through the handle endcap, the inner door panel, and the outer door panel.

2. The door assembly of claim 1 , further comprising a resilient member biasing the latch bar into engagement with the latch base.

3. The door assembly of claim 2 , wherein the resilient member is a compression spring biasing the latch bar in the vertical direction.

4. The door assembly of claim 1 , wherein the latch bar is fixed to the handle body and comprises:
an aperture formed laterally through a first end of the latch bar, the aperture defining a keyed portion; and
a hook extending from a second end in the vertical direction, the second end being opposite the first end along the transverse direction.

5. The door assembly of claim 4 , wherein the handle assembly further comprises a shaft extending laterally from the handle body, the shaft connecting the handle body with the latch bar through the handle endcap via the aperture.

6. The door assembly of claim 5 , wherein the shaft is shaped complimentary to the keyed portion of the aperture such that the latch bar rotates together with the shaft when the handle body is rotated.

7. The door assembly of claim 6 , wherein the shaft is coaxial with the handle body.

8. The door assembly of claim 4 , wherein the latch base comprises a catch extending in the transverse direction, the catch comprising a lip extending in the vertical direction from a distal end of the catch.

9. The door assembly of claim 8 , wherein the lip defines a front face, and wherein a bottom end of the front face is located further forward than a top end of the front face in the transverse direction.

10. The door assembly of claim 1 , wherein the handle endcap is a first handle endcap, the latch bar is a first latch bar, and the latch base is a first latch base, the handle assembly further comprising:
a second handle endcap opposite the first handle endcap along the lateral direction,
a second latch base opposite the first latch base along the lateral direction, and
a second latch bar opposite the first latch bar along the lateral direction, the second latch bar being detachably coupled to the second latch base through the second handle endcap.

11. A home appliance defining a vertical direction, a lateral direction, and a transverse direction, the home appliance comprising:
a body defining a cavity; and
a door assembly pivotally attached to the body for opening and closing the cavity, the door assembly comprising:
an inner door panel;
a latch base fixed to the inner door panel;
an outer door panel pivotally connected to the inner door panel; and
a handle assembly attached to the outer door panel, wherein the handle assembly comprises:
a handle endcap attached to an outer surface of the outer door panel;
a handle body connected with the handle endcap, the handle body being rotatable with respect to the handle endcap; and
a latch bar extending from the handle body such that the latch bar rotates together with the handle body, the latch bar being detachably coupled to the latch base through the handle endcap, the inner door panel, and the outer door panel.

12. The home appliance of claim 11 , wherein the handle assembly further comprises a resilient member biasing the latch bar into engagement with the latch base.

13. The home appliance of claim 12 , wherein the resilient member is a compression spring biasing the latch bar in the vertical direction.

14. The home appliance of claim 11 , wherein the latch bar is fixed to the handle body and comprises:
an aperture formed laterally through a first end of the latch bar, the aperture defining a keyed portion; and
a hook extending from a second end in the vertical direction, the second end being opposite the first end along the transverse direction.

15. The home appliance of claim 14 , wherein the handle assembly further comprises a shaft extending laterally from the handle body, the shaft connecting the handle body with the latch bar through the handle endcap via the aperture.

16. The home appliance of claim 15 , wherein the shaft is shaped complimentary to the keyed portion of the aperture such that the latch bar rotates together with the shaft when the handle body is rotated.

17. The home appliance of claim 16 , wherein the shaft is coaxial with the handle body.

18. The home appliance of claim 14 , wherein the latch base comprises a catch extending in the transverse direction, the catch comprising a lip extending in the vertical direction from a distal end of the catch.

19. The home appliance of claim 18 , wherein the lip defines a front face, and wherein a bottom end of the front face is located further forward than a top end of the front face in the transverse direction.

20. The home appliance of claim 11 , wherein the handle endcap is a first handle endcap, the latch bar is a first latch bar, and the latch base is a first latch base, the handle assembly further comprising:
a second handle endcap opposite the first handle endcap along the lateral direction,
a second latch base opposite the first latch base along the lateral direction, and
a second latch bar opposite the first latch bar along the lateral direction, the second latch bar being detachably coupled to the second latch base through the second handle endcap.
