    Description

    BACKGROUND



    [0001] Generally, refrigerators are electric appliances for storing foods at a low temperature. Such a refrigerator may include a refrigerating compartment and a freezing compartment provided under the refrigerating compartment. Also, the refrigerator may include a plurality of refrigerating compartment doors for opening/closing the refrigerating compartment and a freezing compartment door for opening/closing the freezing compartment.

    [0002] The plurality of refrigerating compartment doors may be horizontally disposed to independently open or close the refrigerating compartment. The plurality of refrigerating compartment doors may include a first refrigerating compartment door and a second refrigerating compartment door disposed at a left side of the first refrigerating compartment door.

    [0003] Generally, a pillar may be rotatably disposed on the first refrigerating compartment door to prevent cool air within the refrigerating compartment from leaking between the refrigerating compartment doors when each of the refrigerating compartment doors closes the refrigerating compartment.

    [0004] The pillar may be spread while the pillar is inserted into a holder provided in the refrigerating compartment when the first refrigerating compartment door is closed and be folded while the pillar is withdrawn from the holder when the first refrigerating compartment door is opened.

    [0005] However, according to the refrigerator according to the related art, such as disclosed in JP2004176941A, there are limitations as follows.

    [0006] First, the pillar may be rotatably coupled to the first refrigerating compartment door. Thus, since a locking device for preventing the pillar from rotating is not provided within the pillar, the pillar may be maintained in an opened state when the first refrigerating compartment door is opened. Also, if the first refrigerating compartment door is strongly opened, the pillar may be folded and then spread again by retroaction thereof.

    [0007] As described above, when a user close the first refrigerating compartment door in the state where the pillar is spread, the pillar may collide with the holder. As a result, the pillar may be damaged, or the first refrigerating compartment door may not be completely closed, and thus, the cool air may leak to the outside.

    [0008] In addition, when the pillar is spread, and the second refrigerating compartment door is closed, the first refrigerating compartment door can not be closed. Thus, the user has to close the second refrigerating compartment door after the first refrigerating compartment door is closed.

    DETAILED DESCRIPTION OF THE EMBODIMENTS



    [0013] Reference will now be made in detail to the embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings.

    [0014] In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration specific preferred embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, and it is understood that other embodiments may be utilized and that logical structural, mechanical, electrical, and chemical changes may be made without departing from the scope of the invention. To avoid detail not necessary to enable those skilled in the art to practice the invention, the description may omit certain information known to those skilled in the art. The following detailed description is, therefore, not to be taken in a limiting sense.

    [0015] Hereinafter, exemplary embodiments will be described with reference to the accompanying drawings.

    [0016] Fig. 1 is a perspective view of a refrigerator according to an embodiment, and Fig. 2 is a partial perspective view of the refrigerator with a first refrigerating compartment door opened.

    [0017] Figs. 1 and 2 illustrate an example of a state in which a second refrigerating compartment door is removed.

    [0018] Referring to Figs. 1 and 2, a refrigerator 1 according to the current embodiment may include a main body 10 having a refrigerating compartment 11 and a freezing compartment 12, a plurality of refrigerating compartment doors rotatably connected to the main body 10 by using a hinge assembly to open or close the refrigerating compartment 11, and a freezing compartment door 23 for opening or closing the freezing compartment 12.

    [0019] The plurality of refrigerating compartment doors may include a first refrigerating compartment door rotatably connected to a left portion of the main body 10 and a second refrigerating compartment door (not shown) rotatably connected to a right portion of the main body 10. That is, in the current embodiment, the first refrigerating compartment door 20 and the second refrigerating compartment door may be disposed on left and right sides, respectively. In some cases, the plurality of refrigerating compartment doors may further include at least a door in addition to the two doors.

    [0020] The freezing compartment door 23 may open or close the freezing compartment 12 by using, for example, a sliding manner. That is, the freezing compartment door may be, for example, a drawer type door. Alternatively, the freezing compartment door 23 may be rotatably coupled to the main body 10.

    [0021] A pillar 30 may be provided on one of the first refrigerating compartment door 20 and the second refrigerating compartment door. The pillar 30 may prevent the cool air within the refrigerating compartment 11 from leaking between the plurality of refrigerating compartment doors when the plurality of refrigerating compartment doors are closed.

    [0022] Fig. 1 illustrates an example of a state in which the pillar 30 is disposed on the first refrigerating compartment door 20.

    [0023] The first refrigerating compartment door 20 may includes an outer case 21 and a door liner 22 connected to the outer case 21. The pillar 30 may be rotatably connected to the door liner 22.

    [0024] The holder 13 in which an upper end of the pillar 30 is accommodated may be disposed on the refrigerating compartment 11. For example, the holder 13 may be disposed on an upper portion of a sidewall of the refrigerating compartment 11. For another example, the holder 13 may be disposed on a lower portion of the sidewall of the refrigerating compartment 11, and a lower end of the pillar 30 may be accommodated into the holder 13. If the first refrigerating compartment door 20 rotates upward or downward about a horizontal hinge shaft, the pillar 30 may be disposed on the sidewall of the refrigerating compartment 11.

    [0025] When the first refrigerating compartment door 20 is closed, the pillar 30 may be spread by an interaction with the holder 13. Thus, the pillar 30 may prevent the refrigerating compartment 20 from communicating with a gap between the plurality of refrigerating compartment doors. That is, the holder 13 may guide the pillar 30 to allow the pillar 30 to rotate.

    [0026] On the other hand, when the first refrigerating compartment door 20 is opened, the pillar 30 is folded by the interaction with the holder 13.

    [0027] In this specification, the state of the pillar 30 illustrated in Fig. 1 may be a state in which the pillar 30 is spread, and the state of the pillar 30 illustrated in Fig. 2 may be a state in which the pillar 30 is folded.

    [0028] In the current embodiment, when the pillar 30 is folded, the rotation of the pillar 30 is prevented by a locking device (that will be described below), and thus the pillar 30 is not spread until the first refrigerating compartment door 20 is closed.

    [0029] Hereinafter, a structure of the pillar 30 according to the current embodiment will be described in detail.

    [0030] Fig. 3 is a view of a state in which a pillar cover is separated from a pillar body constituting a pillar according to an embodiment, Fig. 4 is an exploded perspective view of the pillar according to an embodiment, and Fig. 5 is a view of a first hinge assembly according to an embodiment. Fig. 5 illustrates a first hinge assembly in the state where the first refrigerating compartment door is opened.

    [0031] Referring to Figs. 3 to 5, the pillar 30 according to an embodiment may include a pillar body 310 and a pillar cover 330 coupled to the pillar body 310.

    [0032] The pillar 30 may further include an insulation material 320 accommodated in the pillar body 310. A heater 332 for preventing frosts from being attached to the pillar 30 may be disposed in the pillar cover 330. Thus, in a state where the pillar cover 330 is coupled to the pillar body 310, the heater 332 may contact the insulation material 320.

    [0033] In the current embodiment, when the first refrigerating compartment door 20 is closed, the heater 332 is disposed between the insulation material 320 and the pillar cover 330. Thus, the insulation material 320 prevents heat generated in the heater 332 from being transmitted into the refrigerating compartment 11.

    [0034] Also, the pillar 30 may further include a plurality of hinge assemblies 340, 360, and 370. The plurality of hinge assemblies 340, 360, and 370 may include a first hinge assembly 340 disposed on an upper portion of the pillar 30, a second hinge assembly 360 disposed on a middle portion of the pillar 30, and a third hinge assembly 370 disposed on a lower portion of the pillar 30. Although the pillar 30 includes the three hinge assemblies in the current embodiment, the current embodiment is not limited to the number of hinge assemblies. However, for the smooth rotation of the pillar 30, the hinge assembly may be provided in plurality. For example, the hinge assemblies may be disposed on the upper and lower portions of the pillar, respectively.

    [0035] The third hinge assembly 370 may include a hinge body 372 and a hinge cover 374. A portion of the hinge body 372 may be coupled to the door liner 22. Also, the hinge body 372 includes a hinge shaft. Also, in a state where the hinge shaft is seated on the pillar body 310, the hinge cover 374 covers the hinge shaft.

    [0036] A wire connected to the heater 332 may be withdrawn to the outside through the second hinge assembly 360.

    [0037] The first hinge assembly 340 (hereinafter, referred to as a "hinge") includes a hinge body 355, a rotation shaft 350 rotatably connected to the hinge body 355, and an operator 346 for moving the rotation shaft 350. The rotation shaft 350 may rotate about the hinge body 356 together with the pillar 30.

    [0038] The hinge body 355 may include a coupling part 356 coupled to the door liner 22 and a shaft connection part 357 to which the rotation shaft 350 is connected. The coupling part 356 may be coupled to a side surface of the door liner 22.

    [0039] The first hinge assembly 340 may further include the rotation shaft 350 and an installation part 341 on which the operator 346 is installed. For example, the installation part 341 may be coupled to the pillar body 310. For another example, the installation part 341 may be integrated with the pillar body 310.

    [0040] An opening 345 through which a connection portion between the shaft connection part 357 and the coupling part 356 passes may be defined in the installation part 341.

    [0041] A portion of the operator 346 may protrude outward from the installation part 341 in a state where the operator 346 is seated on the installation part 341. Also, the operator 346 may move by external force. That is, the operator 346 may be movably disposed on the pillar 30.

    [0042] The operator 346 may include a protrusion 347 accommodated in the holder 13 and a press part 348 extending downward from the protrusion 347.

    [0043] The rotation shaft 350 may be disposed under the press part 348, and the press part 348 may selectively press the rotation shaft 350 downward. The rotation shaft 350 may move downward by the compression of the press part 348.

    [0044] The protrusion 347 may be elastically supported by a first elastic member S1. The first elastic member S1 supports the protrusion 347 in a direction in which the protrusion 347 protrudes from the installation part 341. For example, the first elastic member S1 supports the protrusion 347 upward at a lower side of the protrusion 347. For example, the first elastic member S1 may be a coil spring. The current embodiment is not limited to a kind of first elastic member S1. For another example, the first elastic member S1 may elastically support the press part 348.

    [0045] The installation part 341 may include a hole 342 through which the protrusion 347 passes and a first support 344 for supporting the first elastic member S1.

    [0046] The rotation shaft 350 may pass through the shaft connection part 357. The rotation shaft 350 may include a shaft body 351 passing through the shaft connection part 357. Thus, the rotation shaft 350 and the hinge body 355 may relatively rotate with respect to each other.

    [0047] The first hinge assembly 340 further includes a locking device for preventing the rotation shaft 350 and the hinge body 355 from relatively rotating with each other in the state where the first refrigerating compartment 20 is opened.

    [0048] The locking device may include a first locking part 352 protruding from the shaft body 351 and a second locking part 358 interacting with the first locking part 352 and disposed on the shaft connection part 357.

    [0049] The locking part 352 may have a diameter greater than that of the shaft body 351. The first locking part 352 may protrude from an entire circumference of the shaft body 351 or radially protrude from a portion of the shaft body 351. The first locking part 352 may include a locking projection 353, and the second locking part 358 may include a locking groove 359. The locking projection 353 may have a first contact surface 354 contacting the locking groove 359 in a state where the locking projection 353 is inserted into the locking groove 359. Also, the locking groove 359 may have a second contact surface contacting the first contact surface 354. Each of the contact surfaces 354 may be a vertical surface, a tilted surface, or a rounded surface.

    [0050] The first locking part 352 may be elastically supported by a second elastic member S2. A support 343 for supporting the second elastic member S2 may be disposed on the installation part 341. Here, the rotation shaft 350 may pass through the support 343 to guide the rotation of the rotation shaft 350.

    [0051] The second elastic member S2 elastically supports the first locking part 352 in a direction in which the locking projection 353 is inserted into the locking groove 358. For example, the second elastic member S2 may support the first locking part 352 upward at a lower side of the first locking part 352. For example, the second elastic member S2 may be a coil spring. The current embodiment is not limited to a kind of second elastic member S2.

    [0052] In the current embodiment, the rotation shaft 350 extends vertically. Thus, the rotation shaft 350 may relatively rotate with respect to the hinge body 355 in a horizontal direction.

    [0053] To prevent the rotation shaft 350 and the hinge body 355 from rotating in the horizontal direction, the locking projection 353 may vertically move together with the rotation shaft 350 and thus be inserted into the locking groove 359 or withdrawn from the locking groove 359.

    [0054] Although the first locking part 352 includes the locking projection 353, and the second locking part 358 includes the locking groove 359 in the current embodiment, the first locking part 352 may include the locking groove 359, and the second locking part 358 may include the locking projection 353.

    [0055] Alternatively, the first locking part 352 may be one of the locking projection and the locking groove, and the second locking part 358 may be the other one of the locking projection and the locking groove.

    [0056] Fig. 6 is a partial perspective view illustrating an upper portion of the pillar according to an embodiment, and Fig. 7 is a perspective view of a holder according to an embodiment.

    [0057] Referring to Figs. 6 and 7, the protrusion 347 of the operator 346 may have a tilted surface 347A. Thus, the protrusion 347 may have a thickness gradually increasing upward.

    [0058] The holder 13 may have an opening 131 through which the protrusion 347 passes and an accommodation space for accommodating the protrusion 347 passing through the opening 131. The accommodation space 132 may include a first accommodation space 132A extending in parallel with the insertion direction of the protrusion 347 and a second accommodation space 132B bent from the first accommodation space 132A to change the moving direction of the protrusion 347.

    [0059] The accommodation space 132 may include a side surface 133, a top surface 134, and a connection surface 135 connecting the side surface 133 to the top surface 134. Also, the connection surface 135 may contact the tilted surface 347A of the protrusion 347. The connection surface 135 of the accommodation space 132 may be a substantially tilted surface as a protruding surface in the accommodation space 132. That is, the side surface 133 and the top surface 134 may be connected to each other by the connection surface 135 of the protruding portion in the accommodation space 132 without directly connecting the side surface 133 to the top surface 134. Also, the connection surface 135 of the accommodation space 132 may press the protrusion 347 downward while the protrusion 347 is accommodated into the accommodation space 132. Thus, in the current embodiment, the connection surface 135 may be called a push part pressing the protrusion 347.

    [0060] Hereinafter, an operation of the pillar when the first refrigerating compartment door is opened will be described.

    [0061] Fig. 8 is a view of a state before the first hinge assembly is unlocked according to an embodiment, and Fig. 9 is a view of a state in which the first hinge assembly is unlocked according to an embodiment.

    [0062] First, referring to Figs. 2 and 5, external force is not applied to the operator 346 in the state where the first refrigerating compartment door 20 is opened.

    [0063] Thus, the protrusion 347 of the operator 346 may be maintained in the state protruding upward from the pillar 30 by the elastic force of the first elastic member S1, and the first locking part 352 may be supported by the second elastic member S2. Thus, the first and second locking parts 352 and 358 may be locked. That is, the first hinge assembly 340 is locked by the locking device. As described above, in the state where the first hinge assembly 340 is locked, the pillar may be maintained in the folded state as shown in Fig. 2. The pillar 30 does not rotate if downward pressing force is not applied to the operator 346. That is, the pillar 30 may be maintained in the folded state.

    [0064] In this state, when the first refrigerating compartment door 20 rotates and then is closed, the pillar 30 may rotate together with the first refrigerating compartment door 20 in the folded state. While the first refrigerating compartment door 20 is closed, the protrusion 347 of the operator 346 is inserted into the first accommodation space 132A through the opening 131 of the holder 13. Here, the highest point of the protrusion 347 when the insertion of the protrusion 347 into the first accommodation space 132A starts is disposed between the side surface 133 and the top surface 134 of the accommodation space 132.

    [0065] Thus, when the protrusion 347 is initially inserted into the first accommodation space 132A, the push part of the accommodation space 132 may contact the tilted surface 347A of the protrusion 347 to press the protrusion 347 downward as shown in Fig. 8.

    [0066] Thus, when the protrusion 347 is pressed downward, the first elastic member S1 is contracted. Thus, the press part 348 presses the rotation shaft 350 downward move the rotation shaft 350 downward. That is, the rotation shaft 350 may move in a direction in which the locking projection 353 of the first locking part 352 is withdrawn from the locking groove 359 of the second locking part 358. Then, the second elastic member S2 is contracted.

    [0067] Then, when the protrusion 347 is continuously inserted into the first accommodation space 132A, the protrusion 347 and the rotation shaft 350 may further move downward. Thus, as shown in Fig. 9, the locking projection 353 of the first locking part 352 may be completely withdrawn from the locking groove 359 to release the locking of the locking device.

    [0068] Here, in the current embodiment, the locking of the locking device may be released in a state where the protrusion 347 is disposed in the first accommodation space 132A.

    [0069] The protrusion 347 has to be changed in moving direction so as to move the protrusion 347 from the first accommodation space 132A to the second accommodation space 132B. To change the moving direction of the protrusion 347, the locking of the locking device may be released to enable the rotation shaft 350 to rotate. Thus, in the current embodiment, the locking of the locking device may be released in a state where the protrusion 347 is completely inserted into the first accommodation space 132A or before the protrusion 347 is completely inserted into the first accommodation space 132A. However, even though the locking of the locking device is released, the pillar 30 does not rotate before the protrusion 347 moves into the second accommodation space 132B. Thus, the pillar 30 may be maintained in the folded state.

    [0070] When the locking of the locking device is released, the rotation shaft 350 and the hinge body 355 may relatively rotate with respect to each other. Also, while the protrusion 347 moves into the second accommodation space 132B, rotation force may be applied to the protrusion 347. Here, since the hinge body 355 is fixed to the first refrigerating compartment door 20, the pillar 30 may rotate together with the rotation of the rotation shaft 350. Also, when the protrusion 347 is completely inserted into the second accommodation space 132B, the pillar may be completely spread. The locking device may be maintained in the unlocked state in the state where the protrusion 347 is completely accommodated into the second accommodation space 132B.

    [0071] Thus, since the operator 346 and the push part of the holder 13 release the locking of the locking device in the current embodiment, the operator 346 and the push part may be called an unlocking device. Also, the locking device and the unlocking device may be commonly called a rotation restriction unit for selectively restricting the rotation of the pillar (or the rotation shaft).

    [0072] When the first refrigerating compartment door 20 rotates to open the first refrigerating compartment door 20, the protrusion 347 may move from the second accommodation space 132B to the first accommodation space 132A and then be withdrawn from the first accommodation space 132A. Here, the locked state of the locking device may be maintained in the state where the protrusion 347 is disposed in the second accommodation space 132B. Also, the locking device may be locked while the protrusion 347 is withdrawn from the first accommodation space 132A in the state where the protrusion 347 moves to the first accommodation space 132A.

    [0073] While the protrusion 347 moves from the second accommodation space 132B to the first accommodation space 132A, the pillar 30 may be folded. On the other hand, when the protrusion 347 moves from the second accommodation space 132B to the first accommodation space 132A, the locking device may become to a lockable state. Also, when the protrusion 347 is completely withdrawn from the first accommodation space 132A, the locking device may be locked in the state where the pillar 30 is folded.

    [0074] According to the current embodiment, the pillar is folded while the first refrigerating compartment door is opened. Thus, since the rotation of the pillar is prevented by the locking device in the state where the pillar is folded, it may prevent the first refrigerating compartment door from being closed in the state where the pillar is folded.

    [0075] Also, since the folded state of the pillar is maintained in the state where the first refrigerating compartment door is opened, a user may close the first refrigerating compartment door even though the second refrigerating compartment door is closed.

    [0076] Also, since the locking device is automatically locked or unlocked while the first refrigerating compartment door is opened or closed, it may be unnecessary to separately manipulate the locking device by the user.

    [0077] Although the push part is disposed in the accommodation space 132 in the current embodiment, the push part may be disposed outside the holder 13. In this case, the protrusion 347 may be pressed by the push part before the protrusion 347 is inserted into the accommodation space of the holder 13 to release the locked state of the locking device.

    [0078] Also, although the pillar includes the first and second elastic members in the current embodiment, one of the first and second elastic members may be omitted.

    [0079] Also, although the operator and the rotation shaft are separately provided, the operator and the rotation shaft may be integrated with each other.

    [0080] Also, although the pillar is disposed on the first refrigerating compartment door in the current embodiment, the pillar may be disposed on one of the plurality of freezing compartment doors for opening or closing the freezing compartment. Thus, the refrigerating compartment and the freezing compartment may be commonly called a storage compartment, and a door for opening or closing the storage compartment may be called first and second doors.

    [0081] Fig. 10 is an exploded perspective view of a pillar according to another embodiment, and Fig. 11 is a view of a first hinge assembly according to another embodiment. Fig. 11 illustrates a first hinge assembly in a state where a first refrigerating compartment door is opened.

    [0082] This embodiment is the same as the foregoing embodiment except for a first hinge assembly. Thus, only specific parts in the current embodiment will be described below, and descriptions of the same part as that of the foregoing embodiment will be quoted from the foregoing embodiment.

    [0083] Referring to Figs. 10 and 11, a pillar 30 according to the current embodiment may include a pillar body 310 and a pillar cover 330 coupled to the pillar body 310.

    [0084] Also, the pillar 30 may further include a plurality of hinge assembles 440, 360, and 370. The plurality of hinge assembles 440, 360, and 370 may include a first hinge assembly 440 disposed on an upper portion of the pillar 30, a second hinge assembly 360 disposed on a middle portion of the pillar 30, and a third hinge assembly 370 disposed on a lower portion of the pillar 30.

    [0085] The first hinge assembly 440 (hereinafter, referred to as a "hinge") may include a hinge body 450 and an operator 441 rotatably connected to the hinge body 450.

    [0086] The operator 441 may include a protrusion 442 protruding to a side of the pillar 30, e.g., upward from the pillar 30, an extension part 443 extending from the protrusion 442, and a rotation shaft extending downward from the extension part 443 to provide a rotational center of the pillar 30. The rotation shaft 444 may be integrated with the extension part 443 or be coupled to a lower portion of the extension part 443.

    [0087] For another example, the operator 441 may include the protrusion 442 and a rotation shaft 444 extending downward from the protrusion 442. For another example, the operator 441 includes the protrusion 442, and the rotation shaft 444 may be separated from the operator.

    [0088] The hinge body 450 may include a coupling part 451 coupled to a door liner 22 and a shaft connection part 452 connected to the rotation shaft 444 of the operator 441. The coupling part 451 may be coupled to a side surface of the door liner 22.

    [0089] The rotation shaft 444 may pass through the shaft connection part 452. Thus, the rotation shaft 444 and the hinge body 450 may relatively rotate with respect to each other.

    [0090] The first hinge assembly 440 may further include a locking device for preventing the rotation shaft 444 and the hinge body 450 from relatively rotating with each other in a state where the first refrigerating compartment 20 is opened.

    [0091] The locking device may include a first locking part 455 disposed on the rotation shaft 456 and second locking parts 453 and 454 interacting with the first locking part 445 and disposed on the shaft connection part 457.

    [0092] The first locking part 445 may be a protrusion protruding from the rotation shaft 444 in a radius direction. The first locking part 445 may be integrated with the rotation shaft 444 or coupled to the rotation shaft 444.

    [0093] The second locking parts 453 and 454 may include a first accommodation part 453 extending from the shaft connection part 452 in a direction parallel to the extension direction of the rotation shaft 444, e.g., a vertical direction and a second accommodation part 454 extending from a lower end of the first accommodation part 453 in a direction crossing the extension direction of the rotation shaft 444, e.g., a horizontal direction. Here, the second accommodation part 454 may be defined along a circumference of the shaft connection part 452 and thus rounded.

    [0094] Each of the first and second accommodation parts 453 and 454 may be a hole through which the first locking part 445 passes in a state where the rotation shaft 444 is connected to the shaft connection part 452.

    [0095] Also, the first locking part 445 may move along the second locking parts 453 and 454 in a state where the first locking part is accommodated into the second locking parts 453 and 454.

    [0096] For another example, each of the second locking parts 453 and 454 may be a groove in which the first locking part 445 is accommodated. That is, each of the second locking parts 453 and 454 may be a groove in which an inner circumferential surface of the shaft connection part 452 is recessed outward. Also, the second locking parts 453 and 454 may include a first accommodation part extending vertically and a second accommodation part extending from a lower end of the first accommodation part in a horizontal direction.

    [0097] In the current embodiment, the opening or the guide groove may be commonly called an accommodation part.

    [0098] In the current embodiment, each of the second locking parts 453 and 454 may be limited to a shape thereof.

    [0099] The operator 441 may be elastically supported by an elastic member 456. The elastic member 456 may support the operator 441 in a direction in which the protrusion 442 protrudes from the pillar 30. For example, the elastic member 456 may support the operator 441 upward from a lower side of the operator 441. For example, the elastic member 456 may be a coil spring. The current embodiment is not limited to a kind of elastic member 456. For another example, the elastic member 456 may support the rotation shaft.

    [0100] For example, the elastic member 456 may support a lower portion of the extension part 443. Here, the elastic member 456 may surround the rotation shaft 444, and a lower end of the elastic member 456 may be supported by an upper portion of the shaft connection part 452.

    [0101] In the current embodiment, the rotation shaft 444 extends vertically. Thus, the rotation shaft 444 may relatively rotate with respect to the hinge body 450 in a horizontal direction.

    [0102] The relative rotation of the rotation shaft 444 and the hinge body 450 in the horizontal direction may be prevented in a state where the rotation shaft 444 is disposed in the first accommodation part 453. On the other hand, in a state where the rotation shaft 444 is disposed in the second accommodation part 454, the relative rotation of the rotation shaft 444 and the hinge body 450 in the horizontal direction may be enabled. Here, the elastic member 456 may act so that the first locking part 445 is disposed in the first accommodation part 452.

    [0103] Fig. 12 is a view of a state in which the first hinge assembly is unlocked according to another embodiment.

    [0104] Referring to Figs. 2, 7, 11, and 12, external force is not applied to the operator 441 in a state where the first refrigerating compartment door 20 is opened.

    [0105] Thus, the protrusion 442 of the operator 441 may be maintained in the state in which the protrusion 442 protrudes upward from the pillar 30 by elastic force of the elastic member 456, and the first locking member 445 may be disposed in the first accommodation part 453. Thus, the first locking part 445 and the second locking part may be locked.

    [0106] That is, the first hinge assembly 440 is locked by the locking device. As described above, in the state where the first hinge assembly 440 is locked, the pillar 30 may be maintained in the folded state as shown in Fig. 2. The pillar 30 does not rotate if downward pressing force is not applied to the operator 441. That is, the pillar 30 may be maintained in the folded state.

    [0107] In this state, when the first refrigerating compartment door 20 rotates and then is closed, the pillar 30 may rotate together with the first refrigerating compartment door 20 in the folded state. While the first refrigerating compartment door 20 is closed, the protrusion 441 of the operator 442 is inserted into the first accommodation space 132A through the opening 131 of the holder 13. Here, the highest point of the protrusion 442 when the insertion of the protrusion 442 into the first accommodation space 132A starts is disposed between the side surface 133 and the top surface 134 of the accommodation space 132.

    [0108] Thus, when the protrusion 442 is initially inserted into the first accommodation space 132A, the push part of the accommodation space 132 may contact a tilted surface 347A of the protrusion 442 to press the protrusion 442 downward as shown in Fig. 12.

    [0109] Thus, when the protrusion 442 is pressed downward, the elastic member 456 is contracted. Thus, the first locking part 445 may move downward along the first accommodation part 453.

    [0110] Then, when the protrusion 442 is continuously inserted into the first accommodation space 132A, the protrusion 442 and the rotation shaft 444 may further move downward. Thus, the first locking protrusion 452 may move from the first accommodation part 453 to the second accommodation part 454 to release the locking of the locking device.

    [0111] Here, in the current embodiment, the locking of the locking device may be released in a state where the protrusion 442 is disposed in the first accommodation space 132A.

    [0112] The protrusion 442 has to be changed in moving direction so as to move the protrusion 442 from the first accommodation space 132A to the second accommodation space 132B. To change the moving direction of the protrusion 442, the locking of the locking device may be released to enable the rotation shaft 444 to rotate. Thus, in the current embodiment, the locking of the locking device may be released in a state where the protrusion 442 is completely inserted into the first accommodation space 132A or before the protrusion 442 is completely inserted into the first accommodation space 132A. However, even though the locking of the locking device is released, the pillar 30 does not rotate before the protrusion 442 moves into the second accommodation space 132B. Thus, the pillar 30 may be maintained in the folded state.

    [0113] When the locking of the locking device is released, the rotation shaft 444 and the hinge body 450 may relatively rotate with respect to each other. Also, while the protrusion 442 moves into the second accommodation space 132B, rotation force may be applied to the protrusion 442. Here, since the hinge body 450 is fixed to the first refrigerating compartment door 20, the first locking part 445 may move along the second accommodation part 454 together with the rotation of the rotation shaft 444, and thus, the pillar 30 may rotate. Also, when the protrusion 442 is completely inserted into the second accommodation space 132B, the pillar 30 may be completely spread. The locking device may be maintained in the unlocked state in the state where the protrusion 442 is completely accommodated into the second accommodation space 132B.

    [0114] Thus, since the operator 446 and the push part of the holder 13 release the locking of the locking device in the current embodiment, the operator 446 and the push part may be called an unlocking device. Also, the locking device and the unlocking device may be commonly called a rotation restriction unit for selectively restricting the rotation of the pillar (or the rotation shaft).

    [0115] When the first refrigerating compartment door 20 rotates to open the first refrigerating compartment door 20, the protrusion 442 may move from the second accommodation space 132B to the first accommodation space 132A and then be withdrawn from the first accommodation space 132A. Here, the locked state of the locking device may be maintained in the state where the protrusion 442 is disposed in the second accommodation space 132B. Also, the locking device may be locked while the protrusion 442 is withdrawn from the first accommodation space 132A in the state where the protrusion 442 moves to the first accommodation space 132A.

    [0116] While the protrusion 442 moves from the second accommodation space 132B to the first accommodation space 132A, the pillar 30 may be folded. On the other hand, when the protrusion 442 moves from the second accommodation space 132B to the first accommodation space 132A, the locking device may become to a lockable state. Also, when the protrusion 442 is completely withdrawn from the first accommodation space 132A, the locking device may be locked in the state where the pillar 30 is folded.

    [0117] Fig. 13 is a view of a first hinge assembly according to another embodiment, and Fig, 14 is a view of a state in which the first hinge assembly is unlocked according to another embodiment.

    [0118] The current embodiment is the same as the foregoing embodiment except for a structure of each of first and second locking parts. Thus, only specific parts in the current embodiment will be described below, and the same description as the foregoing embodiment will be denoted by the foregoing embodiment.

    [0119] Referring to Figs. 13 and 14, a first locking part according to the current embodiment may be a portion having a diameter greater than that of a shaft body 351. The first locking part 352 may protrude from the whole circumferential surface of the shaft body 351 or radially protrude from a portion of the shaft body 351. The first locking part 352 may include a first locking groove 553 and a second locking projection 554. The second locking part 358 may include a first locking projection 558 inserted into the first locking groove 553 and a second locking groove 559 in which the second locking projection 554 is inserted.

    [0120] The second locking projection 554 has a plurality of tilted surfaces 554A and 554B. The plurality of tilted surfaces 554A and 554B may be tilted so that the tilted surfaces 554A and 554B are gradually closer to the second locking groove 559. Thus, at least a portion of the second locking projection 554 may have a triangular shape. Accordingly, the second locking groove 559 may also have a plurality of tilted surfaces, and at least a portion of the second locking groove 559 may have a triangular shape.

    [0121] At least a portion of a contact surface between the first locking groove 553 and the first locking projection 558 may be a horizontal plane.

    [0122] When a rotation shaft 350 is pressed, the first locking projection 558 may be withdrawn from the first locking groove, and thus, the rotation shaft 350 together with a pillar 30 may be rotatable.

    [0123] Here, when rotation force is removed in a state where the pressed rotation shaft 350 is rotated within a predetermined angle, the rotation shaft 350 may be rotated in a direction in which the second locking projection 554 is inserted into the second locking groove 559 by the plurality of tilted surfaces 554A and 554B of the second locking projection 554, the plurality of tilted surfaces of the second locking groove 559, and a second elastic member S2. Thus, the pillar 30 may be maintained in a folded state without being spread.

    [0124] That is, according to the current embodiment, when rotation force of the pillar 30 is removed in the state where the pillar 30 is not completely spread by the rotation force of the pillar 30, the pillar 30 may be return to its folded state by the first and second locking parts 352 and 358. Thus, in the current embodiment, the second locking projection 554 and the second locking groove 559 may be called a locking guide device for the pillar 30.

    [0125] Unlike the foregoing embodiment, the first locking part 352 may have the configuration of the second locking part, and the second locking part 358 may have the configuration of the first locking part.

    [0126] Although embodiments have been described with reference to a number of illustrative embodiments thereof, it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the scope of the principles of this disclosure. More particularly, various variations and modifications are possible in the component parts and/or arrangements of the subject combination arrangement within the scope of the disclosure, the drawings and the appended claims. In addition to variations and modifications in the component parts and/or arrangements, alternative uses will also be apparent to those skilled in the art.
