Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cargo-carrying box-shaped carrier for transporting a vertically long box-shaped product.

[0002]

[Prior art]

 Conventionally, a box-shaped carrier such as a truck for road transportation, a freight car for rail transportation, and a container for mounting on these is generally simply surrounded by a plate material and partially provided with an opening / closing door. is there.

When a vertically long product such as a refrigerator or a vending machine for food and drink is transported by such a box-shaped carrier, conventionally, the product is placed on a palette so that a forklift can be used. It is fixed. A simple disposable item is used for this pallet. For this reason, the pallets alone cannot prevent the products from rolling sideways during transportation, and the products lined up collide with each other.

In order to prevent the products from colliding with each other during transportation, a wooden frame 2 is assembled so as to surround the outer periphery of the product as shown in FIG. A cushioning material 3 made of a material such as Styrofoam is interposed therebetween.

On the other hand, as a device for fixing the load on the loading platform, a jack is provided on the ceiling, and the upper surface of the load is pressed by the pressing plate on the lower surface (Japanese Utility Model Laid-Open No. 55-151640). Also, there is one that uses a sac which expands by injecting and discharging air instead of the jack (Japanese Utility Model Publication No. 58-26235).

[0006]

[Problems to be solved by the device]

 Among such conventional devices, the method of using a wooden frame requires a lot of materials, but it requires a lot of labor for assembling it, and further, it is disposable and therefore expensive for the treatment after use. There was a problem.

[0007] Furthermore, the conventional fixing device that uses a jack or a stilt on the ceiling cannot handle luggage with greatly different heights, so that there is a problem that a wooden frame must be used together. It was

In view of such conventional problems, the present invention has an object to provide a box-type cargo carrier for freight transportation that does not require the use of a wooden frame or a cushioning material for each product.

[0009]

[Means for Solving the Problems]

 The features of the present invention for solving the above-mentioned conventional problems and achieving the intended purpose are to provide a cargo-carrying box-type carrier having a floor portion on which cargo is placed and a ceiling portion above the floor portion. In this case, a flat plate-shaped pressing support is hung and supported on the ceiling portion via a jack so that the pressing support is provided with an air mat which expands and contracts by injecting and ejecting air on the lower surface of the pressing support.

[0010]

[Action]

 When using this box-shaped carrier, put the cargo on the pallet or arrange it directly on the floor without putting it on the floor, remove the air in the air mat and compress it to operate the jack to lower the pressing support. Stop at a height where the air mat does not touch the cargo. Next, air is injected into the air mat to inflate it. This causes the air mat to press the top of the cargo.

By thus pressing the top surface via the air mat by the pressing support, individual rolling of the cargo during transportation is prevented.

[0012]

【Example】

 Next, an example in which the present invention is applied to a truck bed will be described with reference to FIGS.

In the figure, 10 is a truck and 11 is a box-shaped carrier. A side plate 13 is erected around a floor 12 on which cargo is loaded, the upper surface of the box-type carrier 11 is closed by a ceiling 14, and a closing door 15 is provided at the rear.

A pressure support body 16 is suspended and supported on the ceiling portion 14 via a plurality of jacks 17, 17 ... And an air mat 18 is fixed to the lower surface of the pressure support body 16.

The pressing support 16 has a rectangular frame 19 made of a metal material, and a wire net 20 is stretched on the lower surface of the frame 19 so that the whole is flat. A plurality of pressing supports 16 are provided so as to cover the entire surface below the ceiling portion 14. The jack 17 has four links 23, 23 ... Pivotally mounted in a pantograph-shaped diamond-shaped arrangement between the upper and lower fixing brackets 21, 22. The nuts 24 and 24 having the screw are fixed, and the screw shaft 25 is screwed into the nuts 24 and 24. Then, by rotating the screw shaft 25 in a direction in which the nuts 24 and 24 are moved toward and away from each other, the fixing metal fittings 21 and 2 are expanded and contracted.

The jacks 17 configured as described above are arranged at four positions in the front, rear, left, and right for each pressing support body 16, and the upper fixing metal fitting 21 is fixed to the lower surface of the ceiling portion 14, and the lower fixing metal fitting. 22 is fixed to the upper surface of the pressing support 16. Further, one screw shaft 25 is commonly used by the pair of jacks 17 and 17 arranged in the front-rear direction, and the universal joint 26 is provided at one end of the screw shaft 25, and the handle 27 is fitted to the universal joint 26 to rotate manually. I am trying to be able to do it.

The upper surface of the air mat 18 is fixed to the lower surface of the pressing support 16, and the inner surface of the air mat 18 is filled with air so that the lower surface bulges downward. The filling of air is performed by connecting an injection hose (not shown) connected to the air tank of the truck 10 to the injection port 28 provided in part. Alternatively, a small injection pump (not shown) driven by the power supply of the truck 10 may be used so that both air filling and forced exhaust can be performed.

When using the cargo-carrying box-type carrier configured as described above, the air in the air mat 18 is deflated and contracted, and the pressing support 16 is raised. Product A fixed on 1 is mounted side by side on floor 12. Then, when the mounting is completed under one pressing support 16, the handle 27 is fitted to the universal joint, and the screw shaft 25 is rotated to extend the jack 17 and lower the pressing support 16. Then, the air mat 18 comes into contact with the top surface of the highest product A, or is lowered to the height immediately before it and stopped. After that, the air mat 18 is filled with air and expanded. As a result, the surface of the air mat 18 conforms to the height of each product A, the top surface of each product A is pressed, and rolling is prevented.

The above-described embodiment is an example implemented on a truck bed. In addition, it can be applied to trailers, containers, railroad cars, etc.

[0020]

[Effect of device]

 As described above, the freight transport box type carrier of the present invention is provided with a pressing support body for raising and lowering through a jack on the ceiling part, and an air mat is attached to the lower surface thereof to fill the air mat with air and expand the same. By pressing the top surface of the cargo to prevent it from rolling, even when products with different heights and sizes are loaded, each top surface is pressed according to the height. Moreover, since the product is pressed by the air mat, the loaded products will not be damaged even if no other cushioning material is used. In addition, since rolling is prevented in this way, the product can be safely transported without the need for a protective frame or cushioning material that surrounds the vertically long product to be transported as in the past. There is an advantage that the economical efficiency is remarkably improved by eliminating the need for assembling and disassembling and disposal of waste materials.
