Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shipping container which is less likely to collapse during transportation by a vehicle or the like.

[0002]

2. Description of the Related Art Conventionally, in the transportation of extremely expensive electronic parts and the like, various measures have been taken in order to prevent the load from collapsing due to vibration or shock during transportation.

For example, according to Japanese Patent Laid-Open No. 61-196841, a roll bar is provided in a packing box, a load is arranged inside the roll bar, and a shock absorber is interposed between the roll bar and the load. , To prevent damage to the cargo during transportation.

[0004]

However, in this case, the load is impacted depending on the direction of vibration, and the front and rear,
Absorption and relaxation of vibration in all directions such as left and right and up and down cannot be achieved. In addition, it takes time and effort to interpose a shock absorber between the roll bar and the load, and it becomes difficult to attach the shock absorber depending on the type, size, and loading method of the load. there were.

It is an object of the present invention to provide a shipping container which can easily absorb and reduce vibrations from all directions and at the same time can easily handle a load.

[0006]

Therefore, a first aspect of the present invention provides a floating plate that absorbs vertical vibrations through a spring arranged at the bottom of a box-shaped container body, and an entire inner peripheral surface of the container body. It is composed of an arranged air mat having a predetermined thickness and an air mat arranged on the inner surface of an upper lid detachably attached to the container body.

In a second aspect based on the first aspect, a moving wheel is provided at the bottom of the container body.

In a third aspect based on the first aspect, the air mat arranged on the inner circumference of the container body and the inner surface of the upper lid is
It is formed of an elastic bag having a predetermined thickness, and each has an air inlet.

In a fourth aspect based on the third aspect, the air mat disposed on the inner circumference of the box-shaped container body is composed of four air mats, front and rear, and left and right. The air mats are connected by pipes so that the air communicates with each other.

[0010]

Therefore, in the first aspect of the present invention, since the air mat is arranged along the inner peripheral surface of the inside of the container body, if the load is stored tightly so that there is no gap in the internal space, the front, rear, left and right It is elastically held against vibration and shock from the direction, and the bottom floating plate is supported by springs, and the air mat is also placed on the inner surface of the upper lid,
It is also possible to absorb and mitigate the transmission to the load of vertical vibration and shock. As a result, it is possible to reliably prevent a load from collapsing during transportation by a truck or the like and to safely transport even a fragile item. Also, by opening and closing the upper lid,
You can easily load and unload cargo.

In the second aspect of the invention, since the container body can be freely moved by the wheel, handling before and after transportation becomes very easy.

In the third aspect of the present invention, the air mat can be set to a predetermined elastic force by injecting air as necessary, and depending on the type of cargo, it has soft elasticity or hard elasticity. It can be adjusted or adjusted freely.

In the fourth invention, the air mats inside the container body are communicated with each other so that they face each other, so that even if the air mat receives a strong load in one direction and the load moves in that direction, the air mat on the other side Air is sent to the air mat,
Since it follows the movement of the load, there is no gap,
In this way, the air mat around the load can always elastically retain the space around the load without creating a gap, and the impact on the load can be reliably reduced.

[0014]

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

1 to 5, the container body 1 is composed of a roll box pallet formed in a box shape by a pipe member 2, and a moving wheel 3 is attached to the bottom thereof. An upper lid 4 is detachably attached to an upper portion of the container body 1 via a spring-attached hook 5 for fixing, and an air mat 6 having a predetermined thickness and slightly smaller than the upper lid 4 is arranged on the inner surface thereof. . The air mat 6 is formed of an elastic bag made of rubber or the like, and air is sealed inside from the inlet 7.

On the inner circumference of the container body 1, four air mats 8a, 8b and 9 are provided along the front, rear, left and right wall surfaces.
a and 9b are arranged, and like the air mat 6, they are formed of elastic bags having a predetermined thickness. Each air mat 8a, 8b and 9a, 9b has an inlet 1
0 is formed and the inside can be filled with air.

The air mats 8a, 8b and 9a, 9b
Does not need to be fixed to the inner wall of the container body 1 in particular, and the size is made to match the inner wall so that the air can be closely attached to the inner wall when air is enclosed.

Next, the base frame 1 is attached to the bottom 11 of the container body 1.
The floating plate 12 housed in 4 is supported by a plurality of springs 13, and the floating plate 12 receives the load of the cargo stored inside.

With the above construction, the operation will be described below.

When loading a load on the container body 1, air is filled in the air mats 6, 8a, 8b, 9a, 9b in advance, and the load is stored with the upper lid 4 opened. The cargo is tightly stored in the internal space of the container body 1 so that there is no gap between them.

In this case, by adjusting the air pressure of the air mats 6, 8a, 8b, 9a, 9b according to the shape of the cargo, it is possible to bring them into close contact with each other without any gap. Also,
Depending on the type of cargo, for example a relatively heavy one,
It is also possible to adjust the holding pressure of the cargo to the optimum state by increasing the air filling pressure and reducing the filling pressure of a lightweight and non-seismic one.

After the load is stored, the upper lid 4 is closed and the fixing hook 5 is hooked on the pipe member 2 of the container body 1 to be fixed.

When the container body is transported by a truck or the like, the cargo stored in the container body 1 is elastically supported in the vertical direction by the floating plate 12 of the bottom 11 and the air mat 6 of the upper lid 4. , Vertical vibration and shock are absorbed and relaxed.

Regarding the horizontal front and rear, left and right,
An air mat 8a arranged on the inner peripheral surface of the box-shaped container body 1,
It is elastically held by 8b and 9a, 9b. Therefore, even if vibrations and impacts from the front, rear, left and right of the vehicle are input, the cargo can be stably supported elastically without affecting the load.

As a result, the cargo is less likely to be damaged during transportation and can be safely transported while maintaining the initial quality.

6 and 7, the four air mats 8a, 8b and 9a, 9b arranged inside the container body 1 will be described below. When the air mats 8b and 9b are connected to each other in a communicating state by the pipes 15a and 15b and are strongly compressed in a specific direction, for example, when one of the air mats 8a and 9a is strongly compressed, air is released to the air mats 8b and 9b on the other side to inflate.
It is designed so that there is no gap between it and the cargo.

In this case, the inlet 10 is connected to each pipe 15
a and 15b.

Depending on transportation conditions such as a truck, it is expected that a large horizontal load will be applied during transportation, and in this case, the load may move. If you move,
A gap may be formed between the air mat on the opposite side, which may hinder the subsequent load holding.

However, if the front and rear air mats 8a, 8b and 9a, 9b are communicated with each other in this way, even if the load moves a little in one direction due to a horizontal load, the air mats on the opposite side will move. Since the air moves and inflates the air mat, the gap between the moved cargo is filled, the cargo is elastically held without a gap, and the shock during transportation can be always absorbed.

[0030]

According to the first aspect of the invention, the floating plate which absorbs vertical vibrations through the spring arranged at the bottom of the box-shaped container body, and the predetermined plate arranged on the entire inner peripheral surface of the container body. Since it is composed of an air mat having a thickness of and an air mat arranged on the inner surface of the upper lid detachably attached to the container body,
The cargo stored in the internal space is elastically held against vibrations and shocks from the front, back, left and right, and the floating plate at the bottom and the air mat on the inner surface of the top cover also protect the cargo from vertical vibrations and shocks. As a result, it is possible to reliably prevent the collapse of loads during transportation by trucks etc., safely transport even fragile items, and to open and close the top lid to easily load loads. It can also be unloaded and has excellent workability.

According to the second aspect of the invention, since the moving wheel is arranged at the bottom of the container body, before and after transportation,
The container body has a high degree of freedom of movement, which makes handling it very easy.

According to the third aspect of the invention, the air mat arranged on the inner circumference of the container body and the inner surface of the upper lid is formed of an elastic bag having a predetermined thickness, and each has an air inlet. As for the air mat, by injecting air as necessary, it can be closely attached so that there is no gap with the load, and the elastic force can be adjusted freely, giving a soft elasticity depending on the type of load. Optimal elastic supporting force can be imparted, such as a strong elasticity and a firm elasticity.

According to the fourth invention, the air mat disposed on the inner circumference of the box-shaped container body is composed of four air mats, front and rear, left and right, and front and rear air mats facing each other are air mates. Since the pipes are connected so that they communicate with each other, even if the air mat receives a strong load in one direction and the load moves in that direction, the air is sent to the air mat on the other side and follows the movement of the load. Since there is no gap, the load can always be held without a gap around the load, and the shock applied to the load can be reliably absorbed and relaxed.
