And the rolling of each rolling part 21 adjacent to each other
When the directions are set to be orthogonal to each other,
A method of determining the moving direction of the organizing box 100 , wherein the moving of the organizing box 100 is disabled .

That is, the moving direction determining method is applied.
In regulating box 100, the fixed caster 20 on the lower surface side of the rectangular bottom plate portion 10 of its those that are applied as follows. That is, the rearranging box 100 is made independent as shown in FIG. 1 by combining the bottom plate portion 10 to the door body 34 as shown in FIG. 2, for example. In FIG. 10, a recess 12 as shown in FIGS. 3 and 4 is formed in advance through a substrate portion 11, and a fixed caster 20 is formed with respect to a shaft support 13 protruding into the recess 12. Is attached.

In other words, as shown in FIGS. 1 and 2, the rearranging box 100 has at least a bottom plate portion 10 integrally formed of, for example, a synthetic resin as a material. A concave portion 12 is formed on the lower surface, and a total of four shaft support portions 13, 13 facing each other in front and rear and right and left are formed to protrude into the concave portion 12. On the other hand, the fixed caster 20 has a pair of left and right rolling parts 21, 21 having a substantially disc shape, and a shaft part 22 integrated between the rolling parts 21 at an axis. The fixed caster 20 has its shaft 22 supported by a pair of shafts 13.

The application of the fixed caster 20 to the sorting box 100 which is a moving object is as shown in FIGS.
When the fixed caster 20 formed separately from the bottom plate 10 is stored in the recess 12 formed in the bottom plate 10 on the moving body side which is the rearranging box 100, the shaft 22

This is carried out by forcibly fitting into the bearings 14 of 3 and 13.

In the fixed caster 20 as described above, as shown by the solid line and the imaginary line in FIG. 4, the rolling direction is changed from left to right (solid line) or up and down (virtual line) in the figure.
Can be converted to This is because each shaft portion 22 of the fixed caster 20 constituting the fixed caster 20 is, for example, as shown in FIG. 5, in a bearing portion 14 of a shaft support portion 13 formed on the bottom plate portion 10 side. This is because the shaft is supported by forcibly fitting from the outside (the lower side in the figure in the figure), and can be removed from each bearing portion 14 by performing the reverse operation.

In other words, one shaft portion 22 integrally connecting the two rolling portions 21 on the fixed caster 20 side to each shaft support portion 13 formed on the lower surface of the moving body. To
Since both rolling portions 21 are arranged outside the respective shaft supporting portions 13 (in FIG. 4, left and right sides in FIG. 4), the shaft portions 22 may be forcibly fitted into the corresponding shaft supporting portions 13. is there. In this case, each rolling part 21 is arranged so as to be able to roll the rearranging box 100 in a desired direction. However, the rolling direction of the fixed caster 20 after mounting is wrong or changed afterwards. When it becomes necessary to
The shaft portion 22 is removed from each shaft support portion 13 and another shaft support portion 13 is removed.
By forcibly re-fitting inside, the direction shown by the solid line in FIG. 4 can be changed to the direction shown by the virtual line, for example.

As described above, since the rolling direction of each fixed caster 20 can be freely selected, even if the fixed caster 20 is fixed to the sorting box 100, the moving direction of the sorting box 100 is changed. It can be determined with some degree of freedom. Of course, when a plurality of such fixed casters 20 are attached to the moving object, that is, the organizing box 100 side, if various changes are made as shown in (a) of FIGS. As shown in FIGS. 6 and 7 (b), the movable direction of 100 can be freely determined . That is, the shaft portion 22 of the fixed caster 20

It is to be noted that, for the rearranging box 100, the top plate portion 30 constituting the rearranging box 100 or the lid 50 as shown in FIG. At a position corresponding to each of the recesses 12, for example, as shown in FIGS. 1 and 2, a second recess 40 in which the fixed caster 20 pivotally supported on the bottom plate 10 side is to be stored is formed. Alternatively, the present invention may be implemented such that the shaft 22 of the fixed caster 20 is supported by the shaft support 13 in the second recess 40.

In this sort of sorting box 100, it is assumed that another sorting box 100 similar to this is stacked in order, and in order to enhance the stability when the sorting boxes 100 are stacked, each sorting box 100 is stacked. Is intended to effectively use the fixed casters 20 of the vehicle. That is,
In the rearranging box 100, the second recess 40 is formed in the top plate 30.
Is formed, if another sorting box 100 is stacked on this, the rolling portions 21 of the fixed casters 20 provided in the other sorting box 100 are stored in the second recesses 40. Will be. In this case, since each rolling portion 21 is housed in the second recess 40, the positional displacement between the two storage boxes 100 is prevented, and the upper storage box 100 is positioned at the lower side. On the other hand, they can be stacked in a stable state.

The arrangement box 100 shown in FIG. 1 and FIG.
Since the bottom plate 10 has the same shape so that the top plate 30 can be commonly used as the bottom plate 10, that is, the bottom plate 10 and the top plate 30 can be used even if they are interchanged. The second recess 40 on the side of the bottom 30 is
It is exactly the same as the recess 12 on the side.

[0022]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Now, with reference to the invention configured as described above, the rearranging box 100 according to the embodiment shown in the drawings will be described.
The following is a more detailed description with reference to FIG.

[0023] FIGS. 1 and 2, call the onset Akira is applied
There is shown a organize box 100, which is in the door, but this tidy 10
0 indicates the bottom plate 10 and the top plate 30 as shown in FIG.
And a pair of left and right side plates 32 in which a half back plate 33 is foldably integrated, and a door body 34 covering an opening on the front side are separately formed, and these are combined as shown in FIG. It is formed by this. That is,
In the organizing box 100 of the present embodiment, the constituent members are formed in the same shape as much as possible, and by stacking them, packing and storage when not in use can be performed even in a small space, and manufacturing is also possible. It is intended to be easily performed.

In the rearranging box 100, a total of four recesses 12 are formed in both the bottom plate portion 10 and the top plate portion 30, for example, as shown in FIG. That is, recesses 12 as shown in FIGS. 3 and 4 are formed at the four corners of the bottom plate portion 10 and the top plate portion 30, and each of the recesses 12 has an outer end side. Fitting opening 14
a, the shaft support portions 13 each having a bearing portion 14 at the end thereof are formed. These pivot portions 13 are formed so as to be located inside the surrounding walls in each recess 12. The reason is that each rolling part 21 (so-called wheel) of the fixed caster 20 described later is
This is for enabling rotation without resistance between and the peripheral wall in each recess 12.

The recess 12 formed in the bottom plate 10 of this embodiment has a square shape as shown in FIG. 4, and the recess 12 is recessed inward. This recess 12
As shown in FIGS. 3 and 4, a total of four shaft supports 13 are integrally formed so as to face each other two by two at the center of the substrate part 11 inside each wall, As described above, a bearing portion 14 for fitting and supporting the shaft portion 22 on the fixed caster 20 side is provided at an outer end of each of the shaft support portions 13.
Are formed respectively.

As shown in FIG. 2, each bearing 14 is forcibly fitted with a shaft 22 on the side of the fixed caster 20 to support the shaft. )
Is formed with a fitting opening 14a. Of course, the size of the fitting opening 14a is smaller than the diameter of the shaft portion 22 on the fixed caster 20 side. The shaft 22 is rotatably supported. Needless to say that the shaft portion 22 can be forcibly fitted through the fitting opening 14a, the shaft portion 22 that has been in the shaft support portion 13 can be removed. In addition, since the weight from the rearranging box 100 side is added to the surface of the shaft support 13 opposite to the fitting opening 14a and between the shaft 22,
Even if the fitting opening 14a is left open, no problem occurs.

The fitting opening 14a of each bearing 14 is shown in FIG.
It may be formed and implemented as shown in FIG.
That is, the shaft support 13 in FIG. 10 has an L-shaped bottom surface, and the corners thereof are opposed to each other.
A total of four components are integrally formed at the center of the substrate portion 11, and the outer ends (opposite to the substrate portion 11) of each of the shaft support portions 13 form a gap to be the fitting opening 14 a. Thus, they are separated by a predetermined distance. That is, as shown in FIG. 10, each fitting opening 14a is opened in a cross shape as a whole. A bearing portion 14 is formed at a substantially central portion of each shaft support portion 13 so as to face each other to form a circular cylinder.

Thus, also in the case of the one shown in FIG. 10, if the fixed caster 20 is fitted to the shaft portion 22 from the fitting opening 14a forming one straight line forming a cross, It is rotatably supported in the bearing portion 14. Of course, by performing the reverse operation on the supported shaft portion 22, the shaft portion 22 can be easily removed, and the fitting opening 1 forming another straight line forming the cross is formed.
4a, the shaft portion 22 on the fixed caster 20 side
Can be supported by changing the direction by 90 °.

With respect to such a rearranging box 100, one corresponding to each of the recesses 12 may be formed on the top plate 30 side as well. That is, the recess 12 formed on the top plate 30 side may be the second recess 40 which is simply a recess, and the fixed caster 20 is not attached thereto. However, in the sorting box 100 of the embodiment shown in FIGS. 1 and 2, the bottom plate 10 and the top plate 30
Can be configured as the rearranging box 100 even if the upper and lower sides are exchanged.
The recess 12 on the side and the second recess 40 on the top 30 are substantially the same.

FIGS. 3 to 5 show an embodiment of the fixed caster 20. The fixed caster 20 has a substantially disc-shaped rolling portion 21 and both sides from the axis of the rolling portion 21. And a pair of left and right shaft portions 22 protruding from the shaft.
As shown in FIG. 5, these fixed casters 20 are rotatably mounted on a pair of bearing portions 13, 13 facing each other on the rearranging box 100 side by respective shaft portions 22.

The present invention can also be applied to an assembling wagon 100a as shown in FIG. 9, but in this case, the bottom member shown in FIG. What is necessary is just to apply the said fixed caster 20 to the part 10 as mentioned above. As described above, the movable wagon 100a to which the present invention is applied can freely change its movable direction and can not be moved.
