Abstract

A door for a home appliance includes four hinges which may be interchanged regarding a location on the door, and a series of interconnected arms that allow a pivot axis of the door to be changed from a first direction to a second direction by manipulation of a handle on the door.

First claim

What is claimed is:

1. A laundry-treating apparatus comprising:
a cabinet having an inlet formed therein;
a door configured to open and close the inlet;
first and second fasteners provided on the door, wherein the first and second fasteners are axially symmetrical to each other about a vertical centerline of the door;
a first hinge including:
a first shaft attached to the cabinet;
a housing fixed to the door by the first fastener or the second fastener; and
a first shaft receiving space defined in the housing, wherein the first shaft is configured to be received in the first shaft receiving space;

a second hinge including:
a second shaft coupled to the door, wherein the first and second shafts are coaxial and collectively define a first pivoting axis; and
a third shaft arranged perpendicular to the second shaft wherein the third shaft defines a second pivoting axis about which the door pivots in a second direction different from the first direction;

a third hinge including:
a fourth shaft attached to the door, wherein the third and fourth shafts are coaxial and collectively define the second pivoting axis;
a fourth shaft receiving space provided at the cabinet, wherein the fourth shaft receiving space is configured to receive the fourth shaft therein; and
a receiving body provided at the cabinet and arranged below the fourth shaft receiving space;

a handle including:
a handle body pivotably secured to the door; and
an input fixed to the handle body;

a first linkage provided between the first fastener and the second fastener, wherein the first linkage includes first and second contact points,
wherein when the handle body pivots when the housing is fixed by the first fastener, the input actuates the first contact point to allow the first linkage to move in a direction from the first fastener toward the second fastener, and
wherein when the handle body pivots when the housing is fixed by the second fastener, the input actuates the second contact point to allow the first linkage to move in a direction from the second fastener toward the first fastener,
a first shaft latch configured to secure the first shaft within the first shaft receiving space, wherein when the housing is fixed by the first fastener, the first shaft latch is fixed to a first free end of the first linkage that faces the first fastener, wherein when the housing is fixed by the second fastener, the first shaft latch is fixed to a second free end of the first linkage that faces the second fastener, and wherein the first shaft latch is configured to open or close the first shaft receiving space when the first linkage moves; and
a second linkage, wherein when the first linkage moves the first shaft latch to open the first shaft receiving space, one of the first and second free ends of the first linkage opposite of the first shaft latch moves the second linkage toward the fourth shaft to insert the second linkage into a through hole provided in the receiving body to latch the fourth shaft into the fourth shaft receiving space.

2. The laundry-treating apparatus of claim 1 , further comprising:
a first accommodation groove defined in the first free end of the first linkage, wherein the first shaft latch is configured to be received in the first accommodation groove;
a second accommodation groove defined in the second free end of the first linkage, wherein the first shaft latch is configured to be received in the second accommodation groove;
a cover configured to cover the second shaft within the door;
a cover fastener configured to secure the cover to the door; and
a body fastener configured to secure the fourth shaft to the door, wherein the cover and body fasteners are positioned axially symmetrical with each other about the vertical centerline of the door.

3. The laundry-treating apparatus of claim 2 , wherein the first hinge further includes:
a guide provided at the housing to guide a movement of the first shaft latch; and
a first spring having a first end fixed to the housing and a second end fixed to the first shaft latch, wherein the spring is configured to press the first shaft latch to close the first shaft receiving space.

4. The laundry-treating apparatus of claim 3 , further comprising an elastic member configured to provide an elastic force to the second linkage to open the fourth shaft receiving space.

5. The laundry-treating apparatus of claim 4 , wherein the elastic member includes:
a casing detachably secured to the door, wherein the second linkage passes through the casing; and
a second spring having a first end fixed to the casing and a second end fixed to the second linkage, wherein the second spring is configured to provide an elastic force to the second linkage to open the fourth shaft receiving space.

6. The laundry-treating apparatus of claim 5 , further comprising:
first and second through-holes respectively provided in the casing, wherein the second linkage passes through the first and second through-holes;
a third through-hole defined in the bottom of the casing;
a stopper that extends from the second linkage, wherein the stopper is positioned between the first through-hole and the third through-hole; and
a guide that extends from the stopper and is inserted into the third through-hole, wherein the guide is configured to guide a movement of the second linkage.

7. The laundry-treating apparatus of claim 1 , wherein the second linkage includes:
a second linkage body, wherein when the housing is fixed by the first fastener, the second linkage body contacts the second free end of the first linkage, wherein when the housing is fixed by the second fastener, the second linkage body contact the first free end of the first linkage, wherein when the first linkage moves the first shaft latch to release the first shaft from the first shaft receiving space, the second linkage body moves toward the fourth shaft, and
a fourth shaft latch, wherein the fourth shaft latch is detachably secured to the second linkage body, wherein when the second linkage body moves toward the fourth shaft, the fourth shaft latch is inserted into the through hole provided in the receiving body.

8. The laundry-treating apparatus of claim 7 , wherein the third hinge includes:
a third hinge body fixed to the door;
a shaft support configured to secure the fourth shaft to the third hinge body, wherein the shaft support separates the fourth shaft and the third hinge body from each other;
a guide provided at the third hinge body to guide the fourth shaft latch into the through hole provided in the receiving body; and
a spring having a first end secured to the third hinge body and a second end secured to the fourth shaft latch, wherein the spring is configured to remove the fourth shaft latch from the through hole.

9. The laundry-treating apparatus of claim 1 , further comprising a first lock, wherein when the door opens the inlet, the first lock is configured to lock the first linkage in a predetermined position.

10. The laundry-treating apparatus of claim 1 , wherein the second linkage includes:
a first body, wherein when the housing is fixed by the first fastener, the first body contacts the second free end of the first linkage, wherein when the first linkage moves the first shaft latch to release the first shaft from the first shaft receiving space, the first body moves toward the fourth shaft;
a second body, wherein when the housing is secured by the first fastener, the second body is detachably secured into and between the housing and the second hinge, wherein the first and second bodies have the same shape; and
a fourth shaft latch configured to latch the fourth shaft into the fourth shaft receiving space, w
