The sliding case 100 has a position retracted from the moving rail 300 (see FIGS. 7, 9, etc.) and a position withdrawn from the moving rail 300 (see FIGS. 10, 13, 14, 16, etc.) (Reference) can be provided to enable sliding movement between them. The sliding case 100 can move in the front-back direction along the moving rail 300, and can be pulled in and out of the moving rail 300.

In addition, the moving rail 300 has a position retracted from the fixed rail 200 (see FIGS. 7, 9, 10, 13, etc.) and a position withdrawn from the fixed rail 200 (see FIGS. 14 and 13). 16, etc.) can be provided to enable sliding movement between them. The movable rail 300 can move in the front and rear directions along the fixed rail 200 and can be moved in and out of the fixed rail 200.

The position where the sliding case 100 is retracted with respect to the moving rail 300 is referred to as the first case position (100A, see FIG. 7, etc.), and the position where the sliding case 100 is withdrawn with respect to the moving rail 300 is referred to as the second case position. It may be referred to as location (100B, see FIG. 10, etc.). The sliding case 100 may be provided to be movable along the moving rail 300 between the first case position 100A and the second case position 100B. The second case location 100B may be provided in front of the first case location 100A.

In addition, for convenience of explanation, each component of the sliding case 100 (case body 110, case opening 111, case stopper 114, case roller 115, etc.) is also shown at the first case position 100A. It may be referred to as being located in the second case position (100B), and may be referred to as being movable between the first case position (100A) and the second case position (100B). Likewise, the case storage compartment 112 provided in the sliding case 100 may also be referred to as being located at the first case position 100A to the second case position 100B, and the first case position 100A and the second case position 100B. It may be referred to as being movable between locations 100B.

In addition, the position where the movable rail 300 is retracted with respect to the fixed rail 200 is referred to as the first rail position (300A, see FIG. 7, etc.), and the position where the movable rail 300 is withdrawn with respect to the fixed rail 200 is defined as the first rail position (300A, see FIG. 7, etc.). It may be referred to as a 2-rail position (300B, see FIG. 14, etc.). The movable rail 300 may be provided to be movable along the fixed rail 200 between the first rail position 300A and the second rail position 300B. The second rail position 300B may be provided in front of the first rail position 300A.

When the moving rail 300 maintains the retracted position with respect to the fixed rail 200, that is, the first rail position 300A, the maximum distance that the sliding case 100 can be withdrawn with respect to the inner case 11 is moved. It may correspond to the distance between the first case position 100A and the second case position 100B with respect to the rail 300.

Here, if the sliding case 100 does not secure a sufficient distance to be withdrawn relative to the moving rail 300 while the moving rail 300 maintains the first rail position 300A, the sliding case 100 The degree of opening may not be sufficient. Accordingly, the user's accessibility to the case storage room 112 may be reduced.

In particular, as described in FIGS. 1 to 3, etc., when the sliding case 100 is a refrigerator 1 that is completely inserted into the storage compartment 20 at the first case position 100A, the user's case storage compartment 112 A problem may arise that accessibility may be further restricted.

In contrast, in the case of one embodiment of the present disclosure, the movable rail 300 may be provided to be movable along the fixed rail 200 between the first rail position 300A and the second rail position 300B.

For example, when the sliding case 100 is at the first case position (100A) and the moving rail 300 is at the first rail position (300A) (see FIG. 9), the sliding case 100 is in the inner case (11) It may be in the most retracted position. When the sliding case 100 is at the second case position 100B and the moving rail 300 is at the first rail position 300A (see FIG. 13), the sliding case 100 is pulled out with respect to the inner case 11. However, at this time, the position of the sliding case 100 may not be the position in which the sliding case 100 is maximally withdrawn with respect to the inner case 11. When the sliding case 100 is at the second case position 100B and the moving rail 300 is at the second rail position 300B (see FIG. 16), the sliding case 100 moves up to the inner case 11. It may be in a location where it was withdrawn.

Therefore, the maximum distance that the sliding case 100 can be drawn out relative to the inner case 11 is the distance between the first case position 100A and the second case position 100B with respect to the moving rail 300, and the fixed rail It may correspond to a distance equal to the sum of the distances between the first rail position 300A and the second rail position 300B with respect to (200).

That is, compared to the case where the movable rail 300 maintains the first rail position 300A, when the movable rail 300 is moved to the second rail position 300B, the sliding case 100 moves to the first rail position. It can be pulled out to the front of the refrigerator 1 further by the distance between 300A and the second rail position 300B.

According to this configuration, in the refrigerator 1 according to an embodiment of the present disclosure, the degree to which the sliding case 100 can be opened when it moves along the rails 200 and 300 and is pulled out can be increased. Accordingly, the user's accessibility to the case storage compartment 112 inside the sliding case 100 can be increased, and the user's convenience can be improved.

FIG. 7 is a diagram illustrating a refrigerator according to an embodiment of the present disclosure when the sliding case is at the first case position and the moving rail is at the first rail position.

As shown in FIG. 10, with the sliding case 100 positioned at the second case position 100B and the moving rail 300 positioned at the first rail position 300A, the sliding case 100 is positioned in front of the sliding case 100. When an external force is applied in the direction in which it is drawn out, the external force applied to the sliding case 100 may be transmitted to the moving rail 300.

More specifically, when an external force directed forward is applied to the sliding case 100 at the second case position 100B, the case stopper 114 at the second case position 100B moves the moving rail 300 forward. It can be pressurized. That is, as the movable rail 300 is pressed by the case stopper 114, it can receive an external force in the direction in which it is pulled out with respect to the fixed rail 200. As an example, the case stopper 114 at the second case position 100B may press the rail roller 350 of the moving rail 300 forward, and accordingly the moving rail 300 may move to the first rail position ( 300A), an external force can be received in the direction toward the second rail position (300B).

When the movable rail 300 is moved from the first rail position 300A to the second rail position 300B, the movable rail 300 may be provided so that the locking connection with the fixed rail 200 is released. The movable rail 300 may be slidably movable with respect to the fixed rail 200 as the engagement with the fixed rail 200 is released and may be pulled forward along the fixed rail 200.

More specifically, when a predetermined or more external force directed toward the second rail position 300B is applied to the movable rail 300 at the first rail position 300A, the engaging coupling between the movable rail 300 and the fixed rail 200 This can be released. For example, as the case stopper 114 at the second case position 100B presses the movable rail 300 forward, the engaging coupling between the movable rail 300 and the fixed rail 200 may be released.

As shown in FIG. 12, when the movable rail 300 is pulled out from the first rail position 300A with respect to the fixed rail 200, the locking portion 320 inserted into the insertion portion 220 is an insertion portion ( 220) can be arranged to deviate from this.

Specifically, the locking portion 320 may be configured to be elastically deformable as an external force is applied. The locking portion 320 may be provided to separate from the insertion portion 220 as it is elastically deformed.

As an example, the locking portion 320 has a fixed end 321 fixed to the movable rail body 310, a free end 322 opposite to the fixed end 321, and a free end 322 from the fixed end 321. It may include an extension part 323 extending towards.

The free end 322 can be inserted into the insertion portion 220 at the first rail position 300A. The free end 322 at the first rail position 300A may be engaged with the insertion portion 220. When the movable rail 300 is pulled forward from the first rail position 300A, the free end 322 is separated from the insertion portion 220, and the engagement with the insertion portion 220 may be released.

The fixed end 321 may maintain a fixed position on the movable rail body 310. When the free end 322 is pressed, the engaging portion 320 may be elastically deformed around the fixed end 321. The fixed end 321 may be located on the side in which the moving rail 300 is pulled out with respect to the free end 322. That is, the fixed end 321 may be located in front of the free end 322.

The extension portion 323 may connect the fixed end 321 and the free end 322. The extension portion 323 may be elastically deformed around the fixed end 321 when the free end 322 is pressed. When the extension portion 323 is elastically deformed, the position of the free end 322 with respect to the fixed end 321 may change.

The extension portion 323 is such that the movable rail 300 is easily elastically deformed when the movable rail 300 is pulled out from the first rail position 300A, so that the movable rail 300 is pulled out from the fixed end 321 toward the free end 322. It may be formed to extend in a direction opposite to the direction. In other words, the extension portion 323 may extend rearward from the fixed end 321 toward the free end 322.

As shown in FIG. 8, etc., the locking portion 320 at the first rail position 300A protrudes outward from the movable rail body 310 toward the fixed rail 200 so that it can be inserted into the insertion portion 220. It can have any shape. Therefore, the free end 322 can be located in an outer direction of the movable rail 300 compared to the fixed end 321, and the extension portion 323 moves from the fixed end 321 toward the free end 322. It may extend in an outward direction of (300).

The extension portion 323 may extend rearward from the fixed end 321 toward the free end 322 and may also extend in an outward direction of the movable rail 300. In this case, the extension portion 323 may extend in an inclined direction with respect to the front-back direction of the moving rail 300. At this time, the extension portion 323 can be elastically deformed more efficiently when the free end 322 is pressed.

However, the present invention is not limited to this, and the fixed end 321, free end 322, and extension part 323 may be formed to have various shapes.

The locking portion 320 may be configured to include an elastically deformable material. For example, the engaging portion 320 may be formed of various materials such as plastic materials.

The locking portion 320 may be formed by injection molding integrally with the moving rail body 310. However, the present invention is not limited to this, and the locking portion 320 may be manufactured separately from the moving rail body 310 and then assembled.

With this configuration, the locking portion 320 can be configured to be elastically deformed when subjected to an external force of a predetermined or greater amount. However, the present invention is not limited to this, and the locking portion 320 may be configured in various ways to enable elastic deformation as an external force is applied.

The free end 322 at the first rail position 300A may be located behind the pressing surface 221 of the insertion portion 220. When an external force in the direction in which the free end 322 is drawn out is applied at the first rail position 300A, the pressing surface 221 may be provided to press the free end 322. The free end 322 at the first rail position 300A may be prevented from moving forward by the pressing surface 221 when the locking portion 320 is not provided with sufficient external force to elastically deform.

When a predetermined or more external force is applied to the moving rail 300 at the first rail position 300A, the free end 322 may be pressed against the pressing surface 221 to a degree sufficient to elastically deform the locking portion 320. . In other words, when the movable rail 300 at the first rail position 300A receives an external force greater than a predetermined level, the free end 322 is pressed by the pressing surface 221, so that the extension portion 323 moves to the fixed end ( 321) can be elastically deformed. When the extension portion 323 is elastically deformed, the free end 322 may be separated from the insertion portion 220 while its position relative to the fixed end 321 changes.

The pressing surface 221 may be formed to have an inclination in a direction that gets closer to the rail receiving portion 210 as it moves forward. The pressing surface 221 may be formed to have an inclination that approaches the inside of the fixed rail 200 as it moves forward.

For example, when the insertion portion 220 is provided on the upper part of the fixed rail 200, the pressing surface 221 may be formed to have a shape that slopes downward toward the front.

For example, when the insertion portion 220 is provided at the lower part of the fixed rail 200, the pressing surface 221 may be formed to have a shape that slopes upward toward the front.

As the pressing surface 221 is formed to have such an inclination, when an external force is applied in the direction in which the moving rail 300 at the first rail position 300A is pulled out, the locking portion 320 is pressed against the pressing surface 221. It is possible to receive guidance for leaving the insertion part 220. That is, the catching portion 320 can be separated from the insertion portion 220 more efficiently.

So that the locking part 320 can be guided more efficiently by the pressing surface 221 when it is separated from the insertion part 220, one side of the locking part 320 that is in contact with the pressing surface 221 is pressed against the pressing surface 221. ) can be formed to have a slope corresponding to the slope of ).

That is, one surface of the locking portion 320 in contact with the pressing surface 221 at the first rail position 300A may be formed to have an inclination in a direction that approaches the moving rail body 310 as it moves forward. One surface of the locking portion 320 in contact with the pressing surface 221 may be formed to have an inclination that approaches the inside of the moving rail 300 as it moves forward.

In other words, one surface of the free end 322 in contact with the pressing surface 221 may be formed to have an inclination in a direction that gets closer to the fixed end 321 as it faces forward.

Here, one side of the locking portion 320 that is in contact with the pressing surface 221 may refer to the front side of the locking portion 320.

For example, when the locking part 320 is provided on the upper part of the moving rail 300, the front side of the locking part 320 in contact with the pressing surface 221 at the first rail position 300A moves downward toward the front. It may be formed to have an inclined shape.

For example, when the locking part 320 is provided at the lower part of the moving rail 300, the front side of the locking part 320 in contact with the pressing surface 221 at the first rail position 300A moves upward toward the front. It may be formed to have an inclined shape.

However, it is not limited to this, and the contact surface where the pressing surface 221 and the catching portion 320 come into contact with each other may be formed to have various shapes. As an example, the pressing surface 221 may be formed to have an inclination having the above characteristics, but the locking portion 320 may not. As an example, the catching portion 320 may be formed to have an inclination having the above characteristics, but the pressing surface 221 may not. As an example, both the pressing surface 221 and the catching portion 320 may be formed so as not to have an inclined surface.

When the movable rail 300 pulled out with respect to the fixed rail 200 is re-entered into the fixed rail 200, that is, the movable rail 300 moves from the second rail position 300B to the first rail position 300A. When this occurs, the locking portion 320 of the moving rail 300 may be moved in a direction opposite to the moving direction shown in FIG. 12. When the first rail position 300A is reached on the movable rail 300, the locking portion 320 can be inserted into the insertion portion 220 again, and the movable rail 300 is caught with respect to the fixed rail 200. can be combined

More specifically, as in the example shown in FIG. 12, the engaging portion 320 at a position separated from the insertion portion 220 may maintain an elastically deformed state. Here, when the locking portion 320 is moved to the first rail position 300A, the elastic deformation of the locking portion 320 may be restored. In this case, as shown in FIG. 8, the locking part 320 can be inserted into the insertion part 220 again and can be hooked to the insertion part 220.

With this configuration, the locking portion 320 inserted into the insertion portion 220 at the first rail position 300A is pressed against the pressing surface 221 when the moving rail 300 is pulled out from the first rail position 300A. It can be pressurized by and can be arranged to be separated from the insertion part 220. Accordingly, the movable rail 300 may be released from its engagement with the fixed rail 200 and may slide with respect to the fixed rail 200.

Additionally, with this configuration, when the movable rail 300 is moved from the second rail position 300B to the first rail position 300A, the locking part 320 can be inserted into the insertion part 220. Accordingly, the movable rail 300 can be engaged with the fixed rail 200 and maintain a fixed position with respect to the fixed rail 200.

However, the movable rail 300 is engaged with the fixed rail 200 at the first rail position 300A, and is moved from the first rail position 300A to the second rail position 300B. It may include various configurations that are provided to release the locking connection to the fixed rail 200.

For example, unlike shown in FIGS. 7 and 8, the fixed rail 200 may include a locking portion, and the moving rail 300 may include an insertion portion provided to be engaged with the locking portion at the first rail position 300A. It can be included.

At this time, the locking portion of the fixed rail 200 may be provided to be inserted into the insertion portion of the movable rail 300 at the first rail position 300A. When the movable rail 300 receives an external force greater than a predetermined amount in the direction from the first rail position 300A to the second rail position 300B, the engaging portion of the fixed rail 200 separates from the insertion portion of the movable rail 300. It can be. The locking portion of the fixed rail 200 may be provided to be elastically deformable when pressed. As the engaging portion of the fixed rail 200 is elastically deformed, it may be separated from the insertion portion of the movable rail 300, and the movable rail 300 may be released from its engagement with the fixed rail 200. When the movable rail 300 is moved from the second rail position 300B back to the first rail position 300A, the engaging portion of the fixed rail 200 is restored from its elastic deformation state and is inserted into the insertion portion of the movable rail 300. It can be inserted, and the moving rail 300 can be engaged with the fixed rail 200.

At this time, the engaging portion of the fixed rail 200 may include a fixed end and a free end opposed to the fixed end and inserted into the insertion portion of the movable rail 300. The locking portion of the fixed rail 200 may extend forward from the fixed end toward the free end. The locking portion of the fixed rail 200 may protrude in a direction toward the inside of the fixed rail 200 from the fixed end to the free end.

At this time, the insertion portion of the moving rail 300 may include a pressing surface provided to press the engaging portion of the fixed rail 200. At the first rail position 300A, the pressing surface of the insertion portion of the movable rail 300 may be located behind the engaging portion of the fixed rail 200.

The pressing surface of the insertion portion of the moving rail 300 may be formed to have an inclination in a direction that approaches the rail receiving portion 210 as it moves forward. One surface of the locking portion of the fixed rail 200 that contacts the pressing surface of the insertion portion of the moving rail 300 may be formed to have an inclination in a direction that approaches the inside of the rail receiving portion 210 as it moves forward.

FIG. 14 is a diagram illustrating a refrigerator according to an embodiment of the present disclosure when the sliding case is at the second case position and the moving rail is at the second rail position. FIG. 15 is a cross-sectional view taken along line X-X' of FIG. 14. FIG. 16 is a diagram illustrating a refrigerator according to an embodiment of the present disclosure when the sliding case is at the second case position and the moving rail is at the first rail position.

14 to 16, when the sliding case 100 is at the second case position (100B) and the moving rail 300 is at the second rail position (300B), the sliding case 100 has an inner case (11). ) can be positioned to be maximally drawn out.

As shown in FIG. 16, when the sliding case 100 is at the second case position 100B and the moving rail 300 is at the second rail position 300B, the moving rail 300 is at the first rail position ( Compared to the case in 300A) (see FIG. 13, etc.), the degree to which the case storage compartment 112 of the sliding case 100 is opened may increase. Accordingly, the user's accessibility to the case storage room 112 can be improved, and the user's convenience can be improved.

Meanwhile, as shown in FIG. 15, the fixed rail 200 may include a rail stopper 230. The rail stopper 230 may be provided to prevent the moving rail 300 from being further pulled out with respect to the fixed rail 200 when it reaches the second rail position 300B.

The rail stopper 230 may be formed to have a shape that protrudes toward the moving rail 300. The rail stopper 230 may be provided in the rail receiving portion 210.

The moving rail 300 may further include a moving rail protrusion 330. The movable rail protrusion 330 may protrude from the movable rail body 310 toward the fixed rail 200. When the movable rail 300 is inserted into the rail receiving portion 210, the movable rail protrusion 330 may be disposed inside the rail receiving portion 210.

The movable rail protrusion 330 may be disposed behind the rail stopper 230. The movable rail protrusion 330 can slide along the rail receiving portion 210 together with the movable rail body 310.

The moving rail protrusion 330 may be provided to contact the rail stopper 230 at the second rail position 300B. More specifically, the moving rail protrusion 330 is accessible to the rail stopper 230 as it moves from the first rail position 300A to the second rail position 300B, and at the second rail position 300B It can be in contact with the rail stopper (230).

The movable rail protrusion 330 may be provided to contact the rail stopper 230 at the second rail position 300B to prevent the movable rail 300 from being pulled out with respect to the fixed rail 200. The moving rail protrusion 330 at the second rail position 300B may contact the rear side 232 (see FIG. 17) of the rail stopper 230, and the rail stopper 230 may be in contact with the rear surface 232 of the rail stopper 230 (see FIG. 17). It is possible to prevent the moving rail protrusion 330 from moving forward. Accordingly, when the movable rail protrusion 330 contacts the rail stopper 230, the movable rail 300 can no longer move forward with respect to the fixed rail 200. In addition, the movable rail 300 can be prevented from moving forward with respect to the fixed rail 200 by the movable rail protrusion 330 and the rail stopper 230.

The movable rail 300 may slide with respect to the fixed rail 200 by the distance between the rail stopper 230 and the movable rail protrusion 330. That is, the distance between the first rail position 300A and the second rail position 300B may approximately correspond to the distance between the rail stopper 230 and the movable rail protrusion 330. Accordingly, in a state where the moving rail 300 is at the first rail position 300A and the sliding case 100 is at the second case position 100B, the sliding case 100 is positioned so that the moving rail 300 is positioned at the second rail. As it moves to the position 300B, it can be further pulled out by the distance between the rail stopper 230 and the moving rail protrusion 330.

By the above-described configuration, the sliding case 100 can be moved from a position where it is maximally retracted with respect to the inner case 11 to a position where it is maximally withdrawn.

Below, an example of a process in which the sliding case 100 is moved from a position at which the sliding case 100 is maximally withdrawn to a position at which it is maximally retracted with respect to the inner case 11 will be briefly described.

When the sliding case 100 is at the second case position 100B and the moving rail 300 is at the second rail position 300B, when the user presses the sliding case 100 backward, the sliding case 100 And the moving rail 300 can slide backward.

As an example, the sliding case 100 may be moved from the second case position 100B to the first case position 100A with respect to the moving rail 300. At this time, the moving rail 300 can still maintain the second rail position 300B with respect to the fixed rail 200.

Afterwards, when the sliding case 100 reaches the first case position 100A, the moving rail 300 is pressed by the sliding case 100 and moves from the second rail position 300B to the first rail position 300A. can be moved

As an example, the moving rail 300 in the second rail position 300B may be moved to the first rail position 300A by being pressed backwards by the case roller 115 in the first case position 100A. . Or, as an example, the moving rail 300 at the second rail position 300B is moved by the rail roller 350 or the moving rail body 310 by the back of the front portion 120 at the first case position 100A. It can be pressed backward and moved to the first rail position (300A).

However, the process of inserting the sliding case and the moving rail into the refrigerator according to the spirit of the present disclosure is not limited to what has been described above. What has been described above is only an example of the process of inserting the sliding case 100 and the moving rail 300 into the refrigerator 1 according to an embodiment of the present disclosure.

Figure 17 is an enlarged cross-sectional view showing an enlarged view of C of Figure 15. Figure 18 is an enlarged cross-sectional view showing the rail stopper and the moving rail protrusion when the moving rail is in the first rail position in the refrigerator according to an embodiment of the present disclosure. Figure 19 is an enlarged cross-sectional view showing the rail stopper and the moving rail protrusion when the moving rail is separated from the fixed rail in the refrigerator according to an embodiment of the present disclosure. FIG. 20 is a diagram illustrating the movable rail and the fixed rail as seen from one direction when the movable rail is at the first rail position in the refrigerator according to an embodiment of the present disclosure.

17 to 20, the moving rail 300 may be detachably mounted on the fixed rail 200.

The fixed rail 200 may include a through hole 250 penetrating toward the movable rail 300. The through hole 250 may be formed to communicate with the inside and outside of the rail receiving portion 210. The through hole 250 may be formed on one side of the fixed rail 200 facing the inner wall of the inner case 11.

The through hole 250 may be placed behind the rail stopper 230. The through hole 250 may be placed adjacent to the rear surface 232 of the rail stopper 230.

FIG. 17 is a diagram showing the moving rail 300 at the second rail position 300B. As shown in FIG. 17, the movable rail protrusion 330 at the second rail position 300B may be positioned to cover one side of the through hole 250. The moving rail protrusion 330 at the second rail position 300B may cover the through hole 250 in the rail receiving portion 210.

When the moving rail 300 is at the second rail position 300B, as shown in FIG. 20, the user makes a through hole 250 on one side of the fixed rail 200 on the side coupled to the rail fixing part 11c. You can access the moving rail protrusion 330 through . The user can press the moving rail protrusion 330 at the second rail position 300B through the through hole 250.

The movable rail protrusion 330 may include a connection portion 332 connected to the movable rail body 310 and a pressing portion 331 extending from the connection portion 332. The connecting portion 332 may connect the pressing portion 331 and the moving rail body 310. The connection portion 332 may be fixed to the movable rail body 310.

The pressing portion 331 may cover one side of the through hole 250 at the second rail position 300B. The user can press the pressing part 331 at the second rail position 300B through the through hole 250.

The pressing part 331 may be disposed in front of the connecting part 332. However, the present invention is not limited to this, and for example, the connection part 332 may be placed in various positions, such as in front of the pressing part 331 or above or below.

The moving rail protrusion 330 may be configured to include an elastically deformable material. As an example, the moving rail protrusion 330 may be made of a plastic material. However, the present invention is not limited thereto, and the moving rail protrusion 330 may be made of various materials.

The moving rail protrusion 330 may be provided to be elastically deformable as it is pressed. More specifically, the movable rail protrusion 330 at the second rail position 300B may be elastically deformed as the pressing portion 331 is pressed. For example, as shown in FIG. 18, the user can press the pressing part 331 at the second rail position 300B through the through hole 250, and the pressing part 331 is connected to the movable rail body 310. ) may change location.

As shown in FIG. 17, the pressing portion 331 at the second rail position 300B may be positioned parallel to the rail stopper 230 in the front-back direction. As shown in FIG. 18, when the pressing part 331 is moved in the pressing direction due to elastic deformation, the pressing part 331 is moved laterally in a position parallel to the rail stopper 230 in the front-back direction. You can. In this state, when the moving rail 300 is pulled forward, the pressing portion 331 may be moved forward past the rail stopper 230, as shown in FIG. 19. As shown in FIG. 19, after the pressing part 331 is elastically deformed and moved forward a predetermined distance, the pressing part 331 is attached to the rail stopper 230 while passing through the rail stopper 230. It can be supported by and maintain an elastically deformed state. Accordingly, after moving the pressing unit 331 forward by a predetermined distance, the user can move the moving rail 300 to the front of the fixed rail 200 without having to press the pressing unit 331 any longer. .

With this configuration, the user can easily separate the movable rail 300 from the fixed rail 200 by pressing the movable rail protrusion 330.

Figure 21 is an enlarged cross-sectional view showing the rail stopper and the moving rail protrusion when the moving rail is mounted on the fixed rail in the refrigerator according to an embodiment of the present disclosure.

Referring to FIG. 21, the movable rail 300 may be mounted in a sliding manner with respect to the fixed rail 200.

More specifically, when the movable rail 300 is separated from the fixed rail 200 and mounted on the fixed rail 200, it can be mounted while sliding from the front to the rear of the fixed rail 200.

As an example, the rail stopper 230 may include a front surface 231 that is inclined with respect to the moving direction of the moving rail 300. That is, the front 231 of the rail stopper 230 may be formed to be inclined in the front-back direction. The front 231 of the rail stopper 230 may be provided in front of the rear 232.

For example, the front 231 of the rail stopper 230 may include an inclined surface formed so that the thickness of the rail stopper 230 in the left and right directions increases as it moves from the front to the rear. In other words, the front 231 of the rail stopper 230 may have a shape inclined in a direction that moves away from the rail fixing portion 11c of the inner case 11 as it moves toward the rear.

When the movable rail 300 is mounted on the fixed rail 200 in a sliding manner, the movable rail protrusion 330 contacts the front 231 of the rail stopper 230 and can be moved rearward. When the moving rail protrusion 330 is moved backward, it may be elastically deformed by being pressed by the front surface 231 of the rail stopper 230. As the front 231 of the rail stopper 230 has an inclination, the degree of elastic deformation may increase as the movable rail protrusion 330 moves rearward before being separated from the front 231 of the rail stopper 230. there is. When the movable rail protrusion 330 moves rearward of the rail stopper 230, the elastically deformed shape of the movable rail protrusion 330 may be restored. More specifically, the rail stopper 230 may be provided so that the movable rail protrusion 330 is elastically deformed by pressing the pressing portion 331 of the movable rail protrusion 330.

When the movable rail 300 is moved from the front to the rear of the rail stopper 230, the movable rail protrusion 330 is moved to the front of the rail stopper 230 even if the user does not press the movable rail protrusion 330 separately. It moves along (231) and can be elastically deformed. Accordingly, when mounting the movable rail 300 on the fixed rail 200, the user can easily mount the movable rail 300 in a sliding manner without performing any separate manipulation.

Meanwhile, unlike the front 231 of the rail stopper 230, the rear 232 may not include such an inclined surface. Accordingly, even if the movable rail 300 is pulled forward while the movable rail 300 is mounted on the fixed rail 200, it is possible to prevent the movable rail 300 from being pulled forward beyond the rail stopper 230. You can. In order for the movable rail 300 to be pulled out ahead of the rail stopper 230, a separate operation may be required for the user to press the movable rail protrusion 330 through the through hole 250.
