Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide type storage box for easily storing clothes and the like.

[0002]

2. Description of the Related Art Conventionally, a simple storage box 10 as shown in FIG. 7 has been known. The storage box 10 is composed of an outer box 20 and an inner box 30 fitted in the outer box 20 so as to be freely inserted and removed. The overall size is set to be about the same as Yuri Yuki. Normally, they are stacked and arranged in multiple stages in the push-in. By using the storage box 10 as described above, the space in the press-in, which has been difficult to use in the related art, can be effectively used, and therefore, it tends to be used favorably.

Since many of the items to be stored in the storage box 10 are usually cloth products such as underwear, sheets or towels that are used in daily home life, many items are stored in the storage box 10. It's generally light when packed with. Therefore, the storage box 10 does not need to be made as sturdy as a chest of drawers or a bookcase, and some storage boxes can be easily made of cardboard or the like, but in recent years, both the outer box 20 and the inner box 30 are plastic injection molded products. Is increasing.

[0004] Also, the place of use is in the invisible closet, and is not used in the sense of interior decoration,
Since it is used exclusively functionally, there is a tendency that the cheapest one is preferred.

[0005]

By the way, even in the storage box 10 used for the above-mentioned purpose, if the storage item is pushed until the inner box 30 is full, the storage item is, for example, clothing. Also becomes a considerable weight, and it becomes very difficult to put the inner box 30 in and out of the outer box 20. In particular, in the future aging society, if there is an increasing tendency for elderly people to live alone, the inconveniences that frequently occur in daily life should be eliminated as much as possible.

Therefore, conventionally, a roller is attached to the bottom of the inner surface of the outer box or the bottom of the outer surface of the inner box, and a sill is provided at a portion of the inner or outer box corresponding to the roller, and the roller rolls on the sill. Has been proposed that allows the inner box to be lightly moved in and out. However, in general, the storage box as described above is generally an injection molded product made of synthetic resin, and the injection molded product of such a box body has a dimensional accuracy because the main body is formed of a thin plate-shaped body. Unfortunately, even if a roller is attached to the outer box or the inner box, the sill portion does not always come into contact with the roller due to the distortion of the plate-like body, and therefore, the rolling of the roller always ensures a smooth and stable inner box. It is not always possible to carry out the entry and exit operations.

Further, even if the roller and the sill portion are in contact with each other, when an oblique force is applied to the inner box when the inner box is moved in and out, the roller slides laterally on the surface of the sill portion and the inner box is slanted. When the inner box is slanted, the outer surface of the inner box collides with the inner surface of the outer box, and the two are in sliding contact with each other, which makes it impossible to smoothly move the inner box in and out. It also has points.

Therefore, it is conceivable to apply a conventionally known slide device used for pulling out a steel desk to the storage box as described above. This slide device is normally provided with male rails horizontally on both sides of the drawer corresponding to the inner box, and female rails corresponding to the male rails are provided on the inner side surface of the desk. A roller is attached, and the male rail is fitted to the female rail so as to be supported by the roller, which is extremely complicated in structure. Therefore, in order to manufacture the above-mentioned complicated structure, it is necessary to improve the dimensional accuracy, and therefore the material cost and the labor cost are high and the manufacturing cost is generally increased.

However, for the purpose of the storage box 10 used for organizing the internal space such as push-in, an expensive one does not meet the demand, and it is preferable that the storage box 10 has a function that is as inexpensive as possible. As a normal material, among the plastics, inexpensive polyethylene or polypropylene is preferably used, and the injection molding method in which the outer box 20 or the inner box 30 is molded by one operation is adopted. At present, efforts are being accumulated.

The storage box of the present invention has been made in order to solve the above-mentioned problems of the prior art, and has a stable and smooth in / out operation, and lateral shake can be effectively suppressed. It is an object of the present invention to provide a storage box that can be manufactured at low cost.
