Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a collapsible container for general transportation of cargo materials.

Railway vehicles, large trucks, ships, etc. are used to transport cargo from one area to another remote area.

A large cube-shaped container is mounted on the tower, and the desired cargo is stored inside the container, and the cargo is safely delivered all at once to the required area.

Since this container has a cubic external shape, it can be placed neatly side by side without leaving any gaps even when placed on a vehicle, so there is no unnecessary dead space. Since it can be accommodated, it is possible to carry out the intended safe transportation without causing damage to the members.

However, 1. For example, if a 2Q item is sent by ship from Japan to a foreign country, and the imported goods from the foreign country are expensive, or if parts are sent to a remote location within Japan, it may be necessary to send the 2Q items by land transportation to that remote location. If there are no orders, the used containers have no choice but to be taken home empty.

In such a case - due to the large volume of the container,
There is a problem in that the space occupied on the ship, truck or vehicle that accommodates this becomes large, and the freight for transporting it becomes extra, which is economically disadvantageous.

This invention was made in view of the problems of the prior art, and aims to reduce the size of a hexahedral container by forming it into a box shape when in use and folding it up when not in use. be.

Therefore, in the present invention, two sides of the hexahedron are folded overlapping one of the other four sides.

Embodiments of the invention will be described below with reference to the drawings.

Figure 1 and Figure 2 are regular T16 views showing this embodiment, and some of the sides are 1. Reference numeral 1 denotes a large plate of the main body of the container, which is made of a steel plate or the like, and at the four corners of the upper surface of the container, suspension fittings 2 for hanging the container by a crane or the like are fixedly installed.

For example, a rectangular cylindrical reinforcing frame 3 is fixed to the four circumferences of the top plate 1 by welding. Reference numeral 4 denotes a bottom plate of the container body, and a similar reinforcing frame 5 is fixed to the four peripheries of this bottom plate 4 as well. Legs 6 are fixed to the four corners of the lower surface of the bottom plate 4 by welding. Furthermore, between the two upper and lower reinforcing frames 3 and 5, two pillars 7 are attached to each of the front side and the rear side 111. The strut 7 consists of strut members 7a, 7h each having a bisected structure, and one end of these strut members 7a, 7h is pivotally connected to each other by a hinge member 8 so as to be able to bend in the front-rear direction, and the strut members 7a, 7h The other end of 7h is pivotally connected to the bracket 9 on the side of the reinforcing frames 3 and 5 by a pin 9a so as to be rotatable in the front-rear direction. These upper and lower support members 7a.

The left and right sides of 7h are connected by a blocking plate 10.11, and each of these blocking plates 1.0 on the front and back side,
11 forms a front plate and a back plate of the container body.

2 is a right side plate serving as a shutter, and a long link 1 is suspended from two brackets 1 and 2 protruding from both ends of the inner surface of the plate.

Both ends of a coil spring J5 are fixed between the pin 1.5 (Z) provided at the approximate center of this link 14 and the valley closing plate 10 of the main Ihi plate and the rear plate.

A kite roller 16 is rotatably supported on the side surface of the right end of the right side plate 12, and this guide roller 1
6 is a kite 1) installed on the front and back reinforcing frame 3.
It is now possible to drive on Le 17-hi. Note that the coil spring 15 constantly pulls the right side plate 12 inward.

Further, the right side plate (not shown) can be stored in the same way when folding by adopting the same mounting structure as the right side plate 12. It can also be installed as a single plate or other shutter so as to be housed on the lower surface of the radish 1 or the top 1n of the bottom A no j4.

In a container having such a configuration, the lower part of the right side plate 12 is raised against the coil splinter 15, and the kite roller 16 is moved to the left of the kite 1 and 17-hi in the direction of arrow X. . Continuing this operation, when the position indicated by the chain line Y is reached, the coil spring 15 is expanded to the maximum extent - from this point on, the distance between the support points of the coil spring 15 is shortened, and this coil spring 15, the opening operation of the right side plate 12 is easily performed. When the lower end of the right side plate 12 approaches the reinforcing frame 3, the kite rail 17
It is accommodated and held within the thickness of , and reaches the position indicated by the chain line 2.

Also, like the right side plate, the left 11'A11 face plate can be pulled up along the kite rail and housed and held at the top, or it can be superimposed on the top plate 1 by rotating around the hinge. .

Next, each of the blocking plates 1, 0, which constitutes the front plate and the back plate,
1.1 near the hinge member 8 to the position shown by the chain line in Figure λ・2, these are folded in while rotating around the pin 9a, and finally the top plate 1 is the right side plate] 2 can be folded onto the bottom plate 4. In this way, the folding operation of the container can be performed extremely easily, and since the space occupied after folding is reduced, it is easy to transport the container. When used as a container, assembly can be easily performed by operating the closing plates 10 and 1.1, the right side plate 12, and the right side plate in the opposite manner to that described above.

Figures 3 through 10 show other embodiments of the present invention. Note that the same components as in Fig. 1 and Fig. 2 are given the same reference numerals. Reference numeral 21 denotes a support frame plate attached to the four circumferences of the lower part of the reinforcing frame 3, and a pair of shutter cases 22 are attached to the left and right sides of this support frame plate in the front and back direction.
A shutter 24 is wound and layered around a winding shaft 23 which is installed in the shutter case 22 in the front-rear direction. This shutter 24 is biased in a certain rotational direction by a spring (not shown) attached to the winder 2:3, and manual operation can be performed smoothly while balancing the weight of this splinter and the shutter 24. It looks like this.

In addition, a kite rail 25 having an opening-shaped cross section is provided integrally or separately on each opposing surface of the front and rear support members 7a and 7h, and both ends of the shutter 24 can be smoothly raised and lowered within this kite rail 25. It looks wet. In addition, as shown in FIG. 8, this kite rail 25 has an opening edge curved inward, a para-kink 27 inserted into this curved portion 26, and a shutter 24 so as to be in contact with this backing 27. By raising and lowering the container, the airtightness inside the container can be improved.

- Figures 7, 9 and 10 show the support parts 7a and 7b.
This shows the details of the hinge connection. According to this, one end of each of the support members 7cL and 7b is connected to the flaket 9.
The support member 7a is rotatably supported around a pin 9a suspended from the support member 7a.

The other ends of the pins 7b are rotatably supported by pins 8a and 8b suspended between two opposing hinge members 8.

Therefore, when folding the container, first close the shutter 24.
The shutter 24 is manually pulled up along the kite rail 25, and each support member 7α is moved around the pins Ba, 8b on the winding shaft.

Fold 7b into a dogleg shape and lower the top plate 1 as shown in Figure 10. If this folding operation is continued further, the front and rear closing plates IQ, 11, top plate 1, and bottom plate 5 will be folded 9 so that they overlap each other, as shown in the off-line diagram, reducing the volume of the container. can be achieved.

FIGS. 11, 12 and 13 show still other embodiments of the invention. This differs only in the lifting and lowering structure of the shutter, and the folding structure of the other substrate 10° is exactly the same as in the above embodiment. That is, 28 is a shutter in which a plurality of somewhat wide plates 28a are arranged vertically, and the plates 28a and 28a are rotatably connected to each other, and
A hanging wire 29 is connected to the upper end of the shutter 28 to connect one end of a coil spring 30.The other end of the coil spring 30 is fixed to a stop pin 31 in the shutter case 22, When the shutter 28 is always lowered into the shutter case 22 to form both side walls of the container, the locking tool provided at the lower end of the shutter 28 is fixed to the reinforcing frame 5. It is adapted to be engaged with a fixing member. As shown in FIG. 13, a kite roller 33 is rotatably attached to both ends of the plate 28a constituting the shutter 28 via a bracket 32, and this kite roller 33 is attached to the support members 7a, 7b. In addition, the shutter 28 can be smoothly moved up and down within the kite rail 34 provided integrally along the shutter case 22.

In addition, 35 is a kite wheel for kiting a suspension line.

The folding of the container in this embodiment is also carried out in the same manner as described above.

Figures A-14 to 19 show still other embodiments of the present invention. Even in this example, the plug], 0, 11
The folding structure is the same as that of the above embodiment, but the shutter elevating structure is different. In the figure, reference numeral 36 denotes a shutter p in which a plurality of plate bodies 39 are connected, each of which is composed of a rectangular cylinder 37 and track plates 38 extending downwardly from the bottom of the cylinder 37. One end of a connecting rod 41 is rotatably supported by a pin 42 on a bracket 40 protruding from the lower part of the cylindrical body 37. It has a protrusion 43 that is located inside the cylinder 37A and does not come off from the cylinder 37A, and its connecting rod 41 is slidably provided within the cylinder 37A. 38A is a track plate connected to another cylindrical body 37A, 40A is a bracket, 41
A is continuous. 4.4, 44A are cylinder bodies 37, 37
Kite rollers 46, . 46A is rotatably attached. The kite rollers 46, 46A roll along abbreviated kite rails 47 which are separably provided on each board 7a, 7b, as shown in FIG. 16. Further, one end of a coil splinter 49 is fixed to the lowermost cylindrical body 37 via a hanging wire 48, and the other end of this coil splinter 49 is fixed to a stop pin 50 in the shutter case 22. This coil spring 49 always biases the shutter 36 in the direction of drawing it into the shutter case 22. Therefore, when the shutter 36 is lowered to form the side wall of the container, the lower end of the shutter 36 A stopper provided on the reinforcing frame 5 is adapted to be latched to a fixing member fixed to the reinforcing frame 5. However, it can be used without the splinter 49.

In this shutter elevating structure, the shutter 36 is pulled into the shutter case 22 by the contraction force of the coil spring 49, as in the case of the above embodiment, but when the above-mentioned locking tool is removed from the fixing member. , the bottom cylinder 3
7 is lifted upward by the contraction force of the coil spring 49, and the upper cylindrical body 37 is sequentially moved to the adjacent lower cylindrical body 3.
19, and is housed in the shutter case 22 so as to overlap with the shutter case 7. Next, by folding each of the support members 7a and 7b into a dogleg shape around the hinge member 8 and lowering the top plate 1, the volume of the container can be reduced in the same way as explained in the off-line diagram. As shown in FIG. 9, the space occupied during transportation becomes narrower.

As described above in detail, Mr. C said that according to the present invention, in a container in which two opposing side panels can be folded in two, the other two opposing panels adjacent to the two side panels can be folded into two. By making the two side plates into vertically movable shutters, the folding and assembling operations of the container are extremely simple and reliable, and the container is highly practical as it has a simple structure and is less likely to break down. It will become.
