Abstract

A garment processing device comprising: a cabinet; a door; a first hinge comprising a first shaft disposed on one of the cabinet or the door, and a first shaft containing portion disposed on the other of the cabinet or the door such that the first shaft is contained therein in an attachable/detachable manner; a second hinge comprising a second shaft coupled to the door so as to form a first axis of rotation together with the first shaft and a third shaft for rotatably fixing the second shaft to the cabinet; a third hinge comprising a fourth shaft disposed on one of the cabinet or the door so as to form a second axis of rotation together with the third shaft, and a fourth shaft containing portion disposed on the other of the cabinet or the door such that the fourth shaft is contained therein in an attachable/detachable manner.

First claim

1 . A laundry-treating apparatus comprising:
a cabinet having an inlet; a door configured to open or close the inlet; a first hinge including:
a first shaft positioned on one of the cabinet or the door and axially extending along a first pivoting axis for the door; and
a first receiving space positioned on another one of the cabinet or the door that does not include the first shaft, wherein the first receiving space is configured to removably receive the first shaft therein;
a second hinge including:
a second shaft coupled to the door, wherein the second shafts axially extends along the first pivoting axis; and
a third shaft that pivotably couples the second shaft to the cabinet, wherein the third shaft axially extends along a second pivoting axis for the door that differs from the first pivoting axis;
a third hinge including:
a fourth shaft positioned on one of the cabinet or the door, wherein the fourth shaft axially extends along the second pivoting axis; and
a fourth shaft receiving space positioned on another one of the cabinet or the door that does not include the fourth shaft, wherein the fourth shaft receiving space is configured to removably receive the fourth shaft therein;
a handle positioned on the door; first and second driving linkages positioned to contact the handle, wherein when force is applied to the handle, each of the first and second driving linkages is configured to move toward or away from the handle; a first shaft latch operatively coupled to the first driving linkage and configured to move to open or close the first shaft receiving space during actuation of the first driving linkage; and a driven linkage, wherein when, upon application of force to the handle, the first driving linkage moves the first shaft latch to open the first shaft receiving space, the second driving linkage moves to cause the driven linkage to move toward the third hinge to close the fourth shaft receiving space.

2 . The laundry-treating apparatus of claim 1 , further comprising:
a first fastener configured to be positioned on the door to secure a housing defining the first shaft receiving space such that when the first fastener secures the housing to the door, the first shaft receiving space faces a free end of the first driving linkage; a second fastener configured to be positioned on the door to secure the housing such that when the second fastener secures the housing to the door, the first shaft receiving space faces a free end of the second driving linkage, wherein the second fastener is positioned to be axially symmetric with the first fastener around a vertical line passing through a center of the door; a cover positioned on the door to pivotably secure the second shaft to the door; a cover fastener positioned on the door to secure the cover to the door; and a fastener positioned on the door to secure the fourth shaft to the door, wherein the fastener is positioned to be axially symmetric with the cover fastener around the vertical line passing through the center of the door.

3 . The laundry-treating apparatus of claim 1 , wherein the first hinge further includes:
a housing configured to be secured to the door, the housing defining the first shaft receiving space; a guide provided on the housing and defining a path to guide a movement of the first shaft latch; and a spring having a first end contacting the housing and a second end contacting the latch, wherein the spring provides a force to push the first shaft latch to close the first shaft receiving space.

4 . The laundry-treating apparatus of claim 3 , further comprising:
a first slot defined in the first driving linkage, wherein the first shaft latch is configured to be removably inserted into the first slot; a second slot defined in the second driving linkage, wherein the first shaft latch is configured to be removably inserted into the second slot; a first fastener positioned on the door and configured to secure the housing to face a free end of the first driving linkage; a second fastener positioned on the door and configured to secure the housing to face a free end of the second driving linkage, wherein the second fastener is positioned to be axially symmetric with the first fastener around a vertical line passing through a center of the door; a cover positioned on the door to pivotably secure the second shaft to the door; a cover fastener positioned on the door to secure the cover to the door; and a fastener positioned on the door to secure the fourth shaft to the door, wherein the fastener is positioned to be axially symmetric with the cover fastener around the vertical line passing through the center of the door.

5 . The laundry-treating apparatus of claim 4 , wherein the driven linkage includes:
a driven link positioned between the second driving linkage and the third hinge, wherein when force is applied to the handle to actuate the second driving linkage, the second driving linkages transmits force to cause the driven link to move to close the fourth shaft receiving space; and a spring that supplies an elastic force to move the driven link to open the fourth shaft receiving space.

6 . The laundry-treating apparatus of claim 5 , further comprising:
a casing detachably secured to the door, wherein the driven link passes through the casing, wherein the spring has a first end connected to the casing and a second end coupled to the driven link.

7 . The laundry-treating apparatus of claim 6 , further comprising:
first and second through-holes respectively in top and bottom faces of the casing, wherein the driven link passes through the first and second through-holes; a third through-hole defined in the bottom face of the casing; a stopper extending from the driven link, wherein the stopper is positioned between the first through-hole and the third through-hole; and a guide extending from the stopper and inserted into the third through-hole, wherein the guide directs a movement of the driven link.

8 . The laundry-treating apparatus of claim 4 , wherein the handle includes:
a handle block pivotally secured to the door; and first and second extensions provided on the handle block and spaced apart from each other, wherein the first driving linkage includes a first contact surface, wherein when force applied to the handle causes the handle block to pivot, the first extension presses the first contact surface to move the first driving linkage toward the handle block, wherein the second driving linkage includes a second contact surface, wherein when force applied to the handle causes the handle block to pivot, the second extension presses the second contact surface to move the second driving linkage toward the handle block.

9 . The laundry-treating apparatus of claim 8 , further comprising:
a first rack provided at the first contact surface and protruding from the first contact surface toward the second contact surface; a second rack provided at the second contact surface and protruding from the second contact surface toward the first contact surface; and a connection gear to connect the first rack and the second rack, wherein the connection gear is configured to transmit force between the first rack and the second rack.

10 . The laundry-treating apparatus of claim 8 , wherein the first driving linkage further includes:
a first driving link positioned between the handle and the first hinge, wherein the first driving link includes the first slot and the first contact surface; and a first linkage extension connected to the first driving link, wherein the second linkage further includes: a second driving link positioned to be axially symmetrical with the first driving link around the verti
