Abstract

Provided is a refrigerator which allows a pivoting bar to pivot to seal a gap between a pair of doors regardless of whether the door at which the pivoting bar is not installed between the pair of doors is open or closed. The refrigerator includes a guide device which induces the pivoting bar to pivot. Here, the guide device includes a rack that is moved forward and backward linearly depending on opening and closing of the second door and includes a second magnet built therein, a pinion gear engaged with the rack and pivoting when the rack is moved linearly, and a guide unit which includes a guide groove guiding a guide protrusion and is engaged with the pinion gear to move linearly in a direction opposite to that of the rack to allow the pivoting bar to pivot when the pinion gear pivots.

First claim

What is claimed is:

1. A refrigerator comprising:
a body;
a storage compartment provided in the body and having a front side;
a first door and a second door coupled to the body to open or close the front side of the storage compartment;
a rotating bar coupled to the first door; and
a guide assembly provided at the body to guide the rotating bar, wherein the guide assembly comprises:
a moveable member configured to move in a first direction as the second door is being opened, and to move in a second direction as the second door is being closed, the first direction being opposite to the second direction, and
a guide configured to move away from the front side as the moveable member moves in the first direction while the first door is closed so that the rotating bar rotates away from the second door, and to move toward the front side as the moveable member moves in the second direction while the first door is closed so that the rotating bar rotates toward the second door.

2. The refrigerator of claim 1 , wherein the guide assembly further comprises a base having an opening along which the moveable member moves in the first direction or the second direction.

3. The refrigerator of claim 2 , wherein the opening is configured to allow the moveable member to move linearly.

4. The refrigerator of claim 1 , further comprising:
a protruding portion provided on an upper rear side of the second door to move the moveable member in the first direction or the second direction.

5. The refrigerator of claim 4 , wherein the moveable member includes a contact portion to come in contact with the protruding portion so that the moveable member is moved by the protruding portion in the first direction or the second direction when the second door is being opened or closed, respectively.

6. The refrigerator of claim 5 , wherein the guide assembly further comprises a base having an opening along which the moveable member moves in the first direction or the second direction, and
wherein the protruding portion is positioned below the opening and faces the contact portion while the second door is closed.

7. The refrigerator of claim 5 , wherein the protruding portion of the second door is configured to use a magnetic force to move the moveable member in the first direction when the second door is being opened.

8. The refrigerator of claim 7 , wherein the contact portion comprises a magnet that operates to provide the magnetic force so that the moveable member is moved by the protruding portion in the first direction or the second direction when the second door is being opened or closed, respectively.

9. The refrigerator of claim 7 , wherein the contact portion comprises a first magnet, and the protruding portion comprises a second magnet, wherein the first magnet and the second magnet provide the magnetic force.

10. The refrigerator of claim 1 , wherein the rotating bar comprises a guide protrusion provided on a top of the rotating bar, and the guide comprises a guide groove which guides the guide protrusion as the guide moves away from or toward the front side.

11. The refrigerator of claim 10 , wherein, when the moveable member moves in the first direction and the guide moves away from the front side, the guide protrusion is guided by the guide groove to allow the rotating bar to rotate away from the second door.

12. The refrigerator of claim 10 , wherein, when the moveable member moves in the second direction and the guide moves toward the front side, the guide protrusion is guided by the guide groove to allow the rotating bar to rotate toward the second door.

13. The refrigerator of claim 1 , wherein the first direction and the second direction in which the moveable member moves correspond to a direction toward the front side and a direction away from the front side, respectively.

14. A refrigerator comprising:
a body;
a storage compartment provided in the body and having a front side;
a first door and a second door coupled to the body, the first door and the second door positioned for the front side of the storage compartment;
a rotating bar coupled to the first door; and
a guide assembly provided at the body to guide the rotating bar, the guide assembly including
a moveable member configured to be moved toward the front side by the second door as the second door is being opened, and to be moved away from the front side by the second door as the second door is being closed, and
a guide configured to move away from the front side as the second door moves the movable member toward the front side while the first door is closed so that the guide guides the rotating bar away from the second door, and to move toward the front side as the second door moves the movable member away from the front side while the first door is closed so that the guide guides the rotating bar toward the second door.

15. The refrigerator of claim 14 , wherein the moveable member comprises a magnet, wherein the second door is configured to use a magnetic force of the magnet to move the moveable member toward the front side.

16. The refrigerator of claim 15 , wherein the second door comprises a magnet to attract the magnet of the moveable member to provide the magnetic force.

17. The refrigerator of claim 16 , wherein the second door comprises a protrusion that accommodates the magnet of the second door.

18. A refrigerator comprising:
a body;
a storage compartment provided in the body and having a front side;
a first door and a second door coupled to the body, the first door and the second door positioned on the front side of the storage compartment;
a rotating bar coupled to the first door; and
a guide assembly provided at the body to guide the rotating bar, the guide assembly including
a moveable member configured to move toward the front side as the second door is being opened, and to move away from the front side as the second door is being closed, and
a guide configured to move away from the front side as the movable member moves toward the front side while the first door is closed so that the guide guides the rotating bar away from the second door, to move toward the front side as the movable member moves away from the front side while the first door is closed so that the guide guides the rotating bar toward the second door, and to be moved away from the front side by the rotating bar as the first door is being closed while the guide is moved to the front side when the second door is opened.

19. The refrigerator of claim 18 , wherein the rotating bar is configured to be rotated to cover a gap between the first door and the second door as the second door is being closed from a position of the rotating bar that is substantially perpendicular to the first door while the first door is closed.
