Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage case for efficiently storing clothes and the like, and more particularly to a storage case that is movable by casters.

[0002]

2. Description of the Related Art Various cases have been proposed for accommodating clothes and the like since ancient times, but in recent years, a large number of cases integrally molded of synthetic resin have come into circulation. Then, such a storage case is, for example, an actual flatbed 6
As described in the section of the prior art in JP-A-47138, it is composed of a case main body and a lid, and the casters are attached to the four corners of the lower part of the case main body, and the recesses into which the casters just fit on the upper surface of the lid. It has also been proposed as a storage case with casters in which parts are formed.

Such a conventional storage case with casters is convenient because it can be rolled on the floor, for example, by the casters, and also has a lid and a recessed portion for storing casters formed therein. Therefore, the respective storage cases with casters can be piled up so as not to move to each other in, for example, a closet, which is very useful.

However, even though the storage case with casters is useful as described above, there is still room for improvement. The first point to be improved is that the recess for forming the casters, which is formed in the lid, is an obstacle to taking out the storage case on the caster. In other words, since the caster is completely stored by the recess, it is possible to sufficiently prevent relative movement of the upper and lower storage cases, but if you try to take out only the upper storage case, the caster will not be recessed in the lower storage case. Since it fits in the part, the upper storage case, which is sometimes heavy, cannot be taken out without lifting.

The above-mentioned inconveniences in use are caused by the fact that it is used in practical use.
The same applies to the "storage container" shown in Japanese Patent No. 135. That is, in this “storage container”, as shown in FIG. 9 and paragraph 0014 of the above publication, the “guide groove 1
5, a semi-circular receiving concave portion 16A to 16C is formed in a portion corresponding to the position of each wheel 4A to 4C. "When trying to slide a heavy storage container on the upper side, , The whole must be lifted so that the wheels emerge from the receiving recess.

The second point to be improved is that when this type of storage case is not used, it is merely an obstacle for taking a place containing only air, and in order to eliminate this, the case is placed inside the case body. The point is that the stacking of the main body must be possible. When stacking case bodies, it is necessary to put items such as clothes inside the empty case body and store another overlapping case body, but it is provided on the lower case body side. Since it is also moved by casters, the structure of each part must be able to withstand stacking sufficiently, and each part must have sufficient rigidity even when moved by the casters on the empty case body side. .

Therefore, the present inventors have made various studies on how to improve at least two points of the conventional storage case with casters, and as a result, completed the present invention. .

[0008]

SUMMARY OF THE INVENTION The present invention has been made based on the above-described background, and the problem to be solved is to eliminate the inconvenience in use in a conventional storage case with casters. And to ensure rigidity.

That is, the object of the present invention is to
Even if you put things in and stack them up, you can easily take out the whole thing without putting too much effort,
Moreover, even if you store another case body containing the stored items, it is possible to easily withstand the gravity of the case body, and a storage case with casters that can withstand rolling even if you use the casters as it is. It is to be provided by the configuration.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention as described above is an embodiment of the storage case 100 with casters shown in the drawings, and the present invention will be described below in accordance with the storage case 100 with casters. To do.

FIG. 1 is a vertical cross-sectional view showing two vertically stacked storage cases 100 with casters according to the present invention. The storage cases 100 with casters are shown in FIG.
Is a semi-transparent case body 10 that is semi-transparent so that whether or not a stored item is contained can be visually recognized from the outside, and an upper flange 14 of the case body 10 that is fitted by a stopper 24. Lid 20 that keeps the combined state
And four casters 30 attached to at least four corners of the bottom surface 12, as shown in FIG. 4, all of which are integrally formed of synthetic resin. . The left-right direction of FIG. 1 is the front-back direction of the storage case 100 with casters.

As shown in FIGS. 1, 2 and 4, the case body 10 has a rectangular shape which is long in the rolling direction of each caster 30, and a side wall 11 thereof is shown in FIGS. As shown, the bottom surface 12 is inclined so as to be small. The bottom surface 12 is inclined in this manner so that another case body 10 can be reliably stacked in the empty case body 10 as shown in FIG. 6, for example.

In addition, at four corners of the bottom surface 12 of the case main body 10, as shown in FIGS. 1, 2 and 7, there are caster housing portions 13 that bulge inward and house the respective casters 30 in a rollable manner. Has been formed. Each of the caster housing portions 13 is long in the long side wall direction of the case body 10, and a caster 30 described later is projected from the extended side of the side wall 11 in the up-down direction to the inner side and from the lower side of the bottom surface 12 by about half. It can be stored in. Also,
As shown in FIG. 7, a support shaft mounting groove 1 for mounting the caster 30 by fitting the support shaft 31 of the caster 30 on the side wall of the caster housing portion 13 is provided.
3a is formed, and the upper surface of the caster housing portion 13 serves as a horizontal surface 13b for stably supporting the caster 30 on the other storage case 100 with casters. As shown in FIG. 7, the inner end side of the horizontal surface 13b is in the shape of an arc along the outer shape of the caster 30, and the end thereof is continuous with the bottom surface 12.

From the above, each caster storage portion 13
Has a very high rigidity. Because each of the caster storage portions 13 is formed at the four corners of the bottom surface 12 at the positions where the casters 30 are stored at the above-described positions, the caster storage portions 13 are located at the so-called boundary portions between the side wall 11 and the bottom surface 12, and the casters 30 are placed. The force received through these side walls 1
This is because they can be easily dispersed on the side of 1 and the bottom surface 12.

As shown in FIGS. 6 and 7, the horizontal surface 13b of the caster housing portion 13 is such that when another case body 10 is housed in an empty case body 10,
The caster 30 on the side of the case body 10 to be stored is
As shown in FIG. 7, the case body 10 is received, and coupled with the guide according to the shape of the case body 10, the other case body 10 accommodated in the case body 10 is firmly supported. From this point as well, the rigidity of each caster storage portion 13 itself is high.

On the other hand, an upper flange 14 extending outward from the side wall 11 is integrally formed above the case body 10 as shown in FIGS. The flange 14 has a fitting flange 23 on the lid 20 side.
Is to be fitted outside. Then, as shown in FIGS. 3 and 5, the stopper 24 is provided on the short side wall side of the lid body 20.
By moving the stopper 24 inward, the engaging portion 24a engages with the lower surface of the upper flange 14 on the case body 10 side, as shown in FIG. Will be fitted and fixed to the case body 10.

As shown in FIG. 3, two caster guide grooves 21 parallel to each other are formed on the upper surface of the lid body 20, and each of the caster guide grooves 21 is formed as shown in FIG.
As shown in FIG. 2, the casters 30 have substantially the same length as the span of the pair of front and rear casters 30, and have the same width as the casters 30, as shown in FIG. That is, each caster 30 positioned in the front-rear direction is not limited to the case of the front-rear pair as in the embodiment, and another caster 30 may be provided between the front-rear pair, for example. In order to accommodate all the casters 30 arranged in the front-rear direction in this way and to guide the respective casters 30 in the front-rear direction in a stable state, the casters 30 have the same width. Therefore, as shown in FIGS. 1 and 2, each of the caster guide grooves 21 is provided in the other storage case 1 with casters.
Because each caster 30 on the 00 side is securely stored,
In combination with the action of each arcuate inclined surface 22 described below, the movement of the other storage case with casters 100 stacked with respect to the storage case with casters 100 is reliably prevented.

Each caster guide groove 21 is implemented as a concrete structure as shown in FIG. 8 (a)
The caster guide groove 21 shown in FIG.
It has a vertical surface that is wider than 0, a horizontal bottom surface that is narrower than the caster 30, and an inclined surface 21a that connects the horizontal bottom surface and each vertical surface, and the guide of the caster 30 is always stable. It is designed so that it can be performed in the state of being. On the other hand, the caster 30 is generally formed with a chamfered portion 30a on its side end surface. Therefore, in the caster guide groove 21 shown in FIG. 8A, the chamfered portion 30a formed on the side end surface of the caster 30 contacts the inclined surface 21a due to the weight of the case body 10 itself having the caster 30. And this caster 30
Will be naturally guided to the center of the guide groove 21. Therefore, each caster 30 has a corresponding guide groove 21.
It is always guided so as to be closer to the center of, and is guided with the space R formed on both sides thereof. Therefore, the other storage cases with casters 100 stacked with respect to the storage case with casters 100 can be moved without generating abnormal noise, and the durability of the casters 30 themselves can be improved. .

By forming the caster guide groove 21 as shown in (b) or (c) of FIG. 8, the caster guide groove 2 shown in (a) of FIG. 8 is also formed.
The same effect as the case of 1 can be exhibited. In the caster guide groove 21 shown in FIG. 8B, the vertical surface that is wider than the width of the caster 30 and the caster 30.
The caster guide groove 21 shown in FIG. 8C has a horizontal bottom surface that is narrower than the horizontal bottom surface and an arcuate surface 21b that connects the horizontal bottom surface and each vertical surface. The inclined surfaces 21c continuous from each vertical surface are intersected at the center of the caster guide groove 21.

As shown in FIG. 5, arcuate inclined surfaces 22 are formed at the front and rear ends of each caster guide groove 21, that is, the left and right ends in the drawing of FIG. 1, respectively.
When the storage cases with casters 100 are stacked on the arc-shaped inclined surfaces 22 as shown in FIG. 1, the storage cases with casters 100 on the upper side are formed and the lower sides of the casters 30 located at the front and rear ends, respectively. The outer surface portions are in surface contact with each other, so that movement of the lower side of the stacked storage cases with casters 100 with respect to that is prevented.

Since each of the arcuate inclined surfaces 22 is formed in a literally arcuate shape substantially the same as the outer surface of the caster 30, the storage case 100 with casters shown in the upper side of FIG. The caster 30 on the left side of the drawing has an arc-shaped inclined surface 2 below the caster 30 when the caster 30 on the left side of the drawing is pulled out toward the front side of the person trying to pull it out.
It's easy to get on top 2. Further, in this case, since each caster guide groove 21 has a length corresponding to the span of the casters 30 at the front and rear ends, the caster 30 on the right side in FIG. Therefore, the casters 30 on the right side can easily climb up on the arc-shaped inclined surface 22 on the left side at the end of the removal of the upper storage case 100 with casters. The caster 30 is generally provided with a chamfered portion 30a as shown in FIG. 8 on its side end surface.

Therefore, the storage case with casters 10
When 0 is taken out from the stacked state, even if there is something heavy in the case body 10 because it is heavy, it is necessary to take out the case, for example, lifting the entire storage case 100 with casters. It's easy to do without.

Now, the inside of one case body 10 is emptied, and the other case body 10 is placed inside the case body 10.
When it becomes necessary to stack them as shown in FIGS. 6 and 7, for example, the lid 20 of the emptied storage case 100 with casters is removed, and another caster with other casters is placed in the case body 10. The lid body 20 in which the storage case 100 is stored and removed is, for example, the stored storage case 10 with casters.
It is stacked on the lid 20 of 0. When the storage case 100 with casters is stored, since the case body 10 is guided by the inner surface of the side wall 11 on the side of the empty case body 10, each of the casters 30 is as shown in FIGS. 6 and 7. Therefore, it is surely placed on the horizontal surface 13b in the caster housing portion 13 on the empty case body 10 side.

In this case, since each caster storage portion 13 has a high rigidity as described above, even if there is something stored in the case body 10 of the storage case with casters 100 to be stored and it is heavy. While the weight is received by the horizontal surface 13b, the casters 30 are transmitted almost directly, and, for example, the bottom surface 12 of the case body 10 accommodating the storage case with casters 100 is not deformed.

The above is, for example, an empty case body 1
It is also important when the caster-equipped storage case 100 containing another object is stacked on the caster-equipped storage case 100 housed in 0. In other words, even if there are stored items in both the uppermost storage case 100 with casters and the lower storage case 100 with casters, the weight is transmitted to the caster storage portion 13 of the lowermost case body 10. Therefore, the bottom surface 12 of each case body 10 is not deformed.

Further, in any of the above cases, the casters 3 on the case body 10 side located at the lowermost stage.
Since 0 is firmly supported by the caster storage portion 13, there is no hindrance in its rolling operation, and the movement of each of the casters can be made by pushing or pulling the entire one shown in FIG. 6, for example. It can be surely done by using 30.

[0031]

As described above, according to the present invention, as described in detail in the above embodiment, the caster housing portions 13 that bulge inward are formed at least at the four corners of the bottom surface 12 of the case body 10. Each caster 30 stored in this
Is the inner side of the extension surface of each side wall 11 of the case body 10 and the bottom surface 1 while protruding from the bottom surface 12 by about half.
In addition to being mounted on the second side, at least two rows of caster guide grooves 21 in which the casters 30 forming the front and rear rows are accommodated at the same time are formed on the upper surface of the lid body 20, and at the front and rear ends of each of these caster guide grooves 21, The structure is characterized in that the arc-shaped inclined surface 22 with which the lower outer surface portion of each of the casters 30 on the side of the other storage case with casters 100 abuts is formed, which makes it possible to store stored items and stack them. Even if there is, you can easily take out the whole without much effort, and even if you store the other case body containing the stored items, you can withstand the gravity sufficiently and it is a caster as it is Thus, it is possible to provide a storage case with casters that can withstand rolling even by using a simple structure.
