Abstract

A refrigerator door assembly includes a refrigerator door that has a recess and an alignment mechanism that includes a door hinge. A plate is fixedly attached to the door hinge and positioned at least partially within the recess of the refrigerator door. The plate includes an orienting member configured to extend along an axis of rotation of the door hinge and away from a body of the plate. The refrigerator door is movably positionable between at least a first position and a second position relative to the plate to permit adjustment of a location of the refrigerator door relative to the door hinge. The recess includes a track that slides against the plate in a linear path between the first and second positions of the refrigerator door.

First claim

What is claimed is:

1. A refrigerator door assembly comprising:
a refrigerator door having a recess;
an alignment mechanism including a door hinge and a plate that is fixedly attached to the door hinge; and
the plate positioned at least partially within the recess of the refrigerator door, the plate including an orienting member configured to extend along an axis of rotation of the door hinge and away from a body of the plate, wherein the refrigerator door is movably positionable between at least first and second positions relative to the plate to permit adjustment of a location of the refrigerator door relative to the door hinge, and wherein the recess defines a track that the plate slides against in a linear path as the refrigerator door moves between the first and second positions;
wherein the alignment mechanism further includes a movement element disposed within the plate;
wherein the movement element includes a worm gear secured to the refrigerator door, wherein the worm gear is selectively rotatable to move the refrigerator door between the first and second positions; and
wherein the movement element further comprises a rack gear secured to the plate and wherein a rotational operation of the worm gear translates the worm gear relative to the rack gear.

2. The refrigerator door assembly of claim 1 , wherein the rotational operation of the worm gear translates the refrigerator door between the first position and the second position.

3. The refrigerator door assembly of claim 1 , wherein the plate is disposed at a top of the refrigerator door, and wherein the orienting member at least partially surrounds the door hinge.

4. The refrigerator door assembly of claim 1 , wherein the orienting member includes a cup shaped protrusion.

5. The refrigerator door assembly of claim 1 , wherein the plate includes a cutaway portion defining the first and second positions of the refrigerator door.

6. The refrigerator door assembly of claim 5 , wherein a fastener is extendable into the refrigerator door and positionable within the cutaway portion position, respectively the first position or the second position, respectively.

7. The refrigerator door assembly of claim 1 , wherein the refrigerator door is in the first position when the refrigerator door is positioned adjacent a first edge of the plate and wherein the refrigerator door is in the second position when the refrigerator door is positioned adjacent a second edge of the plate.

8. A refrigerator door assembly comprising:
a refrigerator door having a recess;
a door hinge; and
a plate that is fixedly attached to the door hinge and positioned at least partially within the recess of the refrigerator door, the plate including an orienting member configured to extend along an axis of rotation of the door hinge and away from a body of the plate, wherein the refrigerator door is movably positionable between at least first and second positions relative to the plate to permit adjustment of a location of the refrigerator door relative to the door hinge, and wherein the recess defines a track that the plate slides against in a linear path as the refrigerator door moves between the first and second positions;
wherein a movement element is disposed within the plate;
wherein the movement element includes a worm gear secured to the refrigerator door, wherein the worm gear is selectively rotatable to move the refrigerator door between the first and second positions;
wherein the movement element further comprises a rack gear secured to the plate and wherein a rotational operation of the worm gear translates the worm gear relative to the rack gear; and
wherein the rotational operation of the worm gear translates the refrigerator door between said first position and said second position.

9. The refrigerator door assembly of claim 8 , wherein the refrigerator door is in the first position when the refrigerator door is positioned adjacent a first edge of the plate and wherein the refrigerator is in the second position when the refrigerator door is positioned adjacent a second edge of the plate.

10. The refrigerator door assembly of claim 8 , wherein the plate is disposed at a top of the refrigerator door, and wherein the orienting member at least partially surrounds the door hinge.

11. The refrigerator door assembly of claim 8 , wherein the orienting member includes a cup shaped protrusion.

12. The refrigerator door assembly of claim 8 , wherein the plate includes a cutaway portion defining the first and second positions of the refrigerator door.

13. The refrigerator door assembly of claim 12 , wherein a fastener is extendable into the refrigerator door and positionable within the cutaway portion.
