 TECHNICAL FIELD The present invention relates to a storage cabinet in which a storage container is removably housed in a storage chamber.

[0002]

[Prior Art]

 In recent years, storages such as household refrigerators have been provided with drawer type freezer compartments and vegetable compartments. This is configured such that a storage container integrally having a door for opening and closing the opening can be put into and taken out from a storage room (freezing room or vegetable room) having an open front surface.

Then, as shown in FIG. 7, rollers 2 and 2 are provided on both inner side wall portions 1 and 1 of the storage chamber, respectively, while a side wall portion of the storage container is provided with a direction (in and out) of the storage container. Movable rails 3 extending in the front-back direction are provided. At this time, the movable rail 3 is placed on the roller 2, and the roller 2 relatively rolls on the movable rail 3 so that the movable rail 3 is guided by the roller 2 to move in the front-back direction. It is supposed to do.

Thus, the storage container is smoothly guided in and out of the storage chamber by being guided by the roller 2.

[0005]

[Problems to be solved by the device]

 By the way, as shown in FIG. 7, the movable rail 3 includes a horizontally elongated metal plate whose upper and lower portions are bent outward at right angles to form a front U-shaped portion having an eave-shaped rail portion 3b above the main plate portion 3a. The rail portion 3b is placed on the roller 2. In this case, a required clearance is provided between the main plate portion 3a of the movable rail 3 and the roller 2.

However, in addition to the above-mentioned clearance, when the movable rail 3 is attached to the storage container (door) or when the roller 2 is attached to the inner wall portion 1 of the storage chamber, the dimension in the left-right direction is increased. Mounting variations may occur, and this mounting variation may cause a large gap S of, for example, 5 mm between the main plate portion 3a and the roller 2.

For this reason, rattling in the left-right direction occurs in the storage container (door), and for example, when the storage container is housed, that is, when the door is closed, the positional displacement of the door may become large. The doors in the storage room were sometimes unevenly arranged, which in turn caused the appearance to deteriorate.

Therefore, an object of the present invention is to provide a storage container having a drawer type storage container in a storage chamber, and to provide a storage container capable of preventing rattling of the storage container in the left-right direction as much as possible. There is

[0009]

[Means for Solving the Problems]

 The storage of the present invention includes a storage chamber having an open front surface, a storage container that can be stored in and out of the storage chamber, rollers provided on the left and right inner wall portions of the storage chamber, and left and right sides of the storage container. A movable rail provided on both side surfaces of the movable rail and moved in the front-rear direction by being guided by the roller, and at least one of the movable rails has a convex portion or a concave portion extending in the front-rear direction. In addition to being provided, the roller for guiding the movable rail is provided with a concave portion or a convex portion that fits in the convex portion or the concave portion.

[0010]

[Action]

 According to the above means, at least one of the movable rails is provided with the convex portion or the concave portion extending in the front-rear direction, and the roller for guiding the movable rail is provided with the concave portion or the convex portion fitted into the convex portion or the concave portion. Since the movable rail is positioned in the left-right direction, it is guided by the roller and moves in the front-rear direction. Therefore, even if a large mounting error occurs in addition to the clearance between the movable rail and the roller, the storage container will not rattle in the left-right direction.

【Example】

 An embodiment in which the present invention is applied to a household refrigerator will be described below with reference to FIGS. 1 to 4. First, FIG. 4 shows the overall appearance of the refrigerator 11 as a storage according to this embodiment. Here, the refrigerator 11 is entirely partitioned by a heat-insulating partition wall, a refrigerating chamber that is opened and closed by a double door 12 is formed in the upper part, and four storage chambers whose front faces are opened are formed in the lower part. Has been done.

Specifically, immediately below the refrigerating compartment, an ice making compartment and a first freezing compartment are provided side by side, and a second freezing compartment 13 (see FIG. 2) is provided below it. There is a vegetable room below it. Each of these four storage chambers is, so to speak, a drawer type, and as will be described later, each front opening is provided with a heat insulating door 14, 15, 16, 17 which is integrally provided in the storage container. Have been shut down respectively.

Although the four drawer-type storage chambers have different sizes and the like, they have substantially the same structure for loading and unloading the storage container, and the second freezing chamber 13 is represented as a representative of them. 1 to 3 will be described below.

Although not shown in detail, the freezer compartment 13 is formed by surrounding the upper, lower, left, right, and rear sides with heat insulating walls, and has an opening 13 a on the front surface that is opened and closed by the door 16. Inside the freezer compartment 13, a storage container 18 in the shape of a substantially rectangular container that is completely accommodated in the freezer compartment 13 is housed so that it can be taken in and out as described later. Further, cold air from a cooler (not shown) is supplied into the freezing chamber 13 from above. As a result, the stored items such as foods (not shown) stored in the storage container 18 are stored in the freezer compartment 13 in a frozen state.

As shown in FIG. 1, the left and right inner side wall portions 13b and 13b of the freezer compartment 13 are provided with rollers 19 and 20, respectively, which are located near the front side upper portion. .. The rollers 19 and 20 are rotatably supported by a shaft member 21 and are attached to the inner wall portion 13b via the shaft member 21.

On the other hand, the storage container 18 is integrally provided with the door 16. That is, as shown in FIG. 3, the door 16 has a rectangular shape which is slightly larger than the front opening 13a of the refrigerating chamber 13, and a frame member 22 having a substantially U-shape is screwed to the rear surface of the door 16, for example. Installed. The storage container 18 is fitted into the frame member 22 from above and is held in a state where it does not fall downward.

The left and right sides of the frame member 22 are movable rails 23 and 24 extending in the front-rear direction, respectively. As shown in FIG. 1, the movable rails 23 and 24 have a shape such that the upper and lower parts of a horizontally long rectangular metal plate are bent outward at a substantially right angle, and the movable rails 23 and 24 are respectively provided above the main plate parts 23a and 24a. It is configured to have rail portions 23b and 24b in an eaves shape.

The movable rails 23 and 24 (frame member 22) are provided in the freezer compartment 13 so that the rail portions 23b and 24b are placed on the rollers 19 and 20, respectively. At this time, the rollers 19 and 20 relatively roll the rail portions 23b and 24b, so that the movable rails 23 and 24 can be moved in the front-rear direction, that is, in the direction in which the freezing chamber 13 is taken in and out. Thus, the storage container 18 supported by the frame member 22 is guided by the rollers 19 and 20 through the movable rails 23 and 24 and is taken in and out of the freezer compartment 13.

As shown in FIG. 1, in the present embodiment, of the left and right movable rails 23, 24, the left movable rail 23 is provided with a projecting ridge portion 25 which is a convex portion extending in the front-rear direction. The corresponding groove 19 on the left side is formed with a concave groove 26. In this case, the protruding portion 25 is formed by protruding the rail portion 23b of the movable rail 23 on the lower surface side in a V shape when viewed from the front. On the other hand, the recessed groove portion 26 has a V-shape corresponding to the above-mentioned projected streak portion 25 and is formed over the entire outer circumference of the roller 19.

Thus, the roller 19 guides the movable rail 23 in a state where the concave groove portion 26 is fitted in the ridge portion 25. The rail portion 24b of the right movable rail 24 has a flat plate shape, while the right roller 20 for guiding the rail portion 24b has a flat outer peripheral surface. In addition, the stopper mechanism (not shown) regulates the amount of the movable rails 23, 24 and by extension, the storage container 18 withdrawn from the freezer compartment 13.

Next, the operation of the above configuration will be described. When a user takes out the storage container 18 from the freezer compartment 13 to, for example, take in and out a stored item, the user pulls the door 16 forward. Then, the movable rails 23 and 24 integrated with the door 16 are guided by the rollers 19 and 20, and are smoothly pulled out to the front side by a light operating force, so that the storage container 18 is pulled out from the freezer compartment 13. Further, in order to store the storage container 18 in the freezer compartment 13, the door 16 can be pushed in so that the rollers 19 and 20 can also smoothly move to the back with a light force.

A required clearance is provided between the rollers 19 and 20 and the movable rails 23 and 24 (main plate portions 23a and 24a). When installing 22 or when installing the rollers 19 and 20 on the inner wall portion 13b of the freezer compartment 13, there is a mounting variation in the horizontal dimension of each refrigerator 11, which causes the refrigerators 19 and 20 to move. The gap between the rails 23 and 24 may become large.

However, in the present embodiment, the movable rail 23 is not only placed on the roller 19 but also the concave groove portion 26 and the ridge portion 25 are fitted to each other, so that the movable rails 23 and 24 are movable. As a result, the storage container 18 moves in the front-rear direction while being guided by the rollers 19 and 20 while being positioned in the left-right direction.

Therefore, according to the present embodiment, even if the gap S ′ between the roller 20 and the main plate portion 24a may become large due to the mounting variation, the storage container 18 and thus the door 16 rattle in the left-right direction. Does not occur.

As a result, unlike the prior art in which the door may be displaced in the left-right direction when the door is closed and the appearance may be deteriorated, a plurality of doors 14, 15, 16, 17 cannot be installed. It is possible to prevent a uniform state as much as possible, and prevent deterioration of appearance.

In the above embodiment, the ridge 25 is formed on the movable rail 23 and the concave groove 26 is formed on the roller 19. However, as shown in FIG. 5, for example, as shown in FIG. It is also possible to provide the V-shaped concave groove portion 32 and use the outer peripheral portion of the roller 33 as the mountain-shaped protrusion portion 34. Further, as shown in FIG. 6, instead of the V-shaped concave groove portion 26, a U-shaped concave groove portion 36 extending in the entire outer peripheral direction may be formed in a part of the roller 35.

Besides, the present invention is not limited to the embodiments described above and shown in the drawings, and can be appropriately modified within a range not departing from the gist such as being applicable to general storages other than the refrigerator. It can be implemented.
