First claim

Opening claim text (preview).

The invention claimed is: 1. A refrigerator comprising: a cabinet having a storage compartment; a first door pivotably installed to the cabinet, the first door being configured to open or close one side of the storage compartment; a second door pivotably installed to the cabinet, the second door being configured to open or close a remaining side of the storage compartment, the second door having a pillar configured to be rotated so as to come into contact with the first door; a first link device provided outside of the storage compartment, the first link device being operated in contact with the first door and the second door at a top of the cabinet; and a second link device configured to be operated by the first link device, the second link device serving to rotate the pillar. 2. The refrigerator according to claim 1 , wherein the first link device includes a housing coupled to the top of the cabinet, and wherein the housing is located outside of the storage compartment, which is closed by the first door and the second door, cold air not being supplied to an inside of the housing. 3. The refrigerator according to claim 2 , wherein the first link device further includes: a first bar configured to be pushed by the first door; a second bar configured to be pushed by the second door; and a rotation gear engaged and rotated between the first bar and the second bar. 4. The refrigerator according to claim 3 , wherein the first bar and the second bar respectively include accommodation regions, in which part of the rotation gear is accommodated, and wherein the rotation gear is placed in the accommodation regions so as to overlap the first bar and the second bar. 5. The refrigerator according to claim 1 , wherein the second link device includes: a first link member configured to be pushed and operated by the first link device; a second link member configured to rotate the pillar; and a transmission member configured to transmit an operation of the first link member to the second link member. 6. The refrigerator according to claim 5 , wherein the second link device further includes an elastic member configured to elastically support the first link member so that the first link member is moved in a rearward direction of the cabinet when external force applied to the first link member is removed. 7. The refrigerator according to claim 5 , wherein the transmission member includes: a first rotator configured to be engaged with and rotated by the first link member; a second rotator configured to be engaged with and rotated by the second link member; and a connection bar configured to connect the first rotator and the second rotator to each other. 8. The refrigerator according to claim 7 , wherein the first rotator is located outside a region defined by a gasket, which is located between the door and the cabinet, and wherein the second rotator is located inside the region defined by the gasket, which is located between the door and the cabinet. 9. The refrigerator according to claim 5 , wherein the second link member includes: a first connector configured to be engaged with and moved by the transmission member; and a second connector having one end rotatably connected to the first connector and a remaining end rotatably connected to the pillar. 10. The refrigerator according to claim 9 , wherein the first connector includes: a first extending portion configured to extend in a rearward direction of the cabinet; and a second extending portion configured to extend toward the first door at a prescribed angle in relation to the first extending portion. 11. The refrigerator according to claim 9 , wherein the second connector includes: a first connecting portion connected to the second extending portion; and a second connecting portion bent from the first connecting portion at a prescribed angle. 12. The refrigerator according to claim 11 , wherein the second connector simultaneously performs linear movement and rotation when the first connector is linearly moved. 13. The refrigerator according to claim 11 , wherein the first connecting portion has a longer length than a length of the second connecting portion. 14. The refrigerator according to claim 1 , further comprising a rotation assistance device installed to a rotating shaft configured to rotate the pillar, the rotation assistance device serving to assist rotation of the pillar. 15. The refrigerator according to claim 14 , wherein the rotation assistance device includes: a first cam supported by an elastic member, the first cam being rotated along with the pillar; and a second cam engaged with the first cam. 16. The refrigerator according to claim 1 , wherein the pillar is operated so as to be unfolded when the first door and the second door are changed in state so as to close the storage compartment. 17. The refrigerator according to claim 1 , wherein, in a state in which the first door and the second door close the storage compartment, the pillar is rotated so as to be folded in relation to the second door when any one of the first door and the second door is rotated to open the storage compartment. 18. The refrigerator according to claim 1 , further comprising: a first drawer located on a side of the first door; and a second drawer located on a side of the second door, wherein the first drawer and the second drawer have the same width. 19. The refrigerator according to claim 18 , wherein the first drawer and the second drawer are arranged in the same horizontal plane, and wherein the first drawer and the second drawer are configured so as to be pulled outward independently of each other. 20. The refrigerator according to claim 1 , wherein the first door and the second door have the same width.
