Abstract

A refrigerator door assembly includes a refrigerator door having a recess. An alignment mechanism includes a plate and a door hinge. The plate is fixedly attached to the door hinge and positioned at least partially within the recess of the refrigerator door. 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.

First claim

What is claimed is:

1. A refrigerator door assembly comprising:
a refrigerator cabinet;
a refrigerator door having a recess; and
an alignment mechanism including a plate, a door hinge, and a door hinge axis of rotation,
wherein the plate is coupled to the door hinge, at least partially disposed around the door hinge axis of rotation, and positioned at least partially within the recess of the refrigerator door,
wherein the refrigerator door is movably positionable between at least a first position and a second position relative to the plate to permit translation of the refrigerator door relative to the door hinge and the door hinge axis of rotation,
wherein the door hinge and the door hinge axis of rotation are substantially fixed relative to the refrigerator cabinet,
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 in a first rotational direction or a second rotational direction to respectively move the refrigerator door to the first position or the second position,
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 in relation to the rack gear translates the refrigerator door between the first position and the second position.

3. The refrigerator door assembly of claim 1 , wherein the plate includes an orienting member configured to extend along the door hinge axis of rotation and away from a body of the plate.

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

5. The refrigerator door assembly of claim 3 , wherein the orienting member is a cup shaped protrusion.

6. The refrigerator door assembly of claim 1 , wherein the alignment mechanism also includes a fastener to hold a cage relative to the refrigerator door, wherein the fastener is extendable into the refrigerator door and positionable within a cutaway portion of the plate.

7. The refrigerator door assembly of claim 1 , wherein the recess includes a track that slides against the plate as the refrigerator door moves between the first and second positions.

8. The refrigerator door assembly of claim 1 , wherein the worm gear is axially fixed with respect to a cage and wherein the cage is fixed to the refrigerator door.

9. The refrigerator door assembly of claim 8 , wherein rotation of the worm gear in the first rotational direction causes the refrigerator door to move toward the first position and wherein rotation of the worm gear in the second rotational direction causes the refrigerator door to move toward the second position.

10. The refrigerator door assembly of claim 9 , further comprising:
an actuator, wherein the actuator is selectively engageable with the worm gear to rotate the worm gear.

11. The refrigerator door assembly of claim 1 , wherein the recess includes a track that is configured to slide against the plate when the refrigerator door moves toward the first position and when the refrigerator door moves toward the second position.
