DESCRIPTION OF THE PREFERRED EMBODIMENTS A cardboard cushioning material according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a cardboard cushioning material according to a first embodiment of the present invention. The rectangular cardboard piece 3 shown in the figure constitutes the cardboard cushioning material of the present invention, and as shown in FIG. 2, a trapezoidal flap 3a, 3a formed with a cut and a fold at the center, as shown in an exploded view. It is provided with a long hole 3 on both sides
c, 3c are provided, and further, a bent portion 3b,
3b is formed. The solid line in the figure is a cut, and the dotted line is a fold.

The vehicle-mounted communication device main body 1 shown in FIG. 1 is inserted into vacancies 4a, 4a of cardboard cushioning materials 4, 4 arranged on both sides. Projections 4b, 4b,... Protrude from the periphery in the space 4a of the cardboard cushioning material 4, and these projections 4b,
4b abut on the in-vehicle communication device body 1 to regulate the position of the in-vehicle communication device body 1 in the left, right, up and down directions.

The vehicle-mounted communication device main body 1 is inserted into the cardboard box 6 while being inserted into the cardboard cushioning members 4 and 4 as described above. The rectangular cardboard piece 3 is placed thereon with the fold indicated by the dotted line in FIG. 2 being bent. Then, the legs of the bracket 2 are connected to the oblong holes 3c, 3c of the rectangular cardboard piece 4.
, The trapezoidal flaps 3a, 3a are turned down, the instruction manual 5 is placed thereon, and the lid of the cardboard box 6 is closed.

FIG. 3 shows a state immediately before the feet of the bracket 2 are inserted into the elongated holes 3c, 3c of the rectangular cardboard piece 4, and FIG. 4 shows a state in which the trapezoidal flaps 3a, 3a are lowered. Since the tips of the bent portions 3b and 3b are in contact with the lid of the cardboard box 6, the position of the rectangular cardboard piece 4 in the vertical direction is regulated.

The height of the trapezoidal flaps 3a, 3a is higher than the height of the bent portions 3b, 3b.
In the case 3a, the rising angle is kept at least at an acute angle. The trapezoidal flaps 3a, 3a regulate the position of the bracket 2 in the width direction (upper right, lower left in FIG. 1).

The length of the folds of the trapezoidal flaps 3a, 3a is the bottom of the trapezoid, and can be made sufficiently long. be able to. Further, since the adjacent cuts of the trapezoid flaps 3a, 3a are slanted, the trapezoid flaps 3a, 3a can be easily raised. That is, it is easy to pack and take out the product.

FIG. 5 shows the positional relationship among the product 1, the cardboard cushioning materials 4, 4, the bracket 2, and the rectangular cardboard piece 2 in the packaged state. The position in the length direction (upper left and lower right in FIG. 1) of the bracket 2 is regulated by the in-vehicle communication device main body 1 as shown in FIG. Even when the in-vehicle communication device main body 1 and the bracket 2 are moved by deforming the protrusions 4b of the cardboard cushioning members 4, 4 by impact, the elongated holes 3c, 3c around the rectangular holes 3c, 3c are not damaged. It is desirable to increase the width of 3c and 3c. When the projection 4b is hard, the width of the long holes 3c, 3c can be reduced to eliminate backlash.

FIG. 6 is a perspective view showing a cardboard cushioning material according to a second embodiment of the present invention. A rectangular cardboard piece 7 shown in the figure has a trapezoidal flap 7a similar to that of the first embodiment,
7a are provided with bent portions 7b, 7b and elongated holes 7c, 7c. This rectangular cardboard piece 7 has the same function as the rectangular cardboard piece of the first embodiment.

In this example, the trapezoidal flaps 7a, 7a are creased at the center, and the rectangular corrugated cardboard pieces 7 are provided with slots 9a, 9a at positions corresponding to the slots 7c, 7c.
The cardboard piece 9 having the following is used to overlap the rectangular cardboard piece 7. With such a configuration, the trapezoidal flaps 7a, 7a do not jump up the member placed on the rectangular cardboard piece 7, and the member can be easily accommodated.
Further, since the cardboard pieces are stacked, the strength is increased.

FIG. 7 is a perspective view showing a cardboard cushioning material according to a third embodiment of the present invention. A rectangular cardboard piece 8 shown in the figure has a trapezoidal flap 8a similar to that of the first embodiment,
8a are provided with bent portions 8b, 8b and elongated holes 8c, 8c. This rectangular cardboard piece 8 has the same function as the rectangular cardboard piece of the first embodiment. In this example, since the trapezoidal flap bending portions 8b are folded back, the strength for regulating the vertical position of the rectangular cardboard piece 8 can be increased.

FIG. 8 is a perspective view showing a cardboard cushioning material according to a fourth embodiment of the present invention, and FIG. 9 is a sectional view showing a use state of the cardboard cushioning material. A rectangular cardboard piece 10 shown in the figure is a trapezoidal flap 10 similar to that of the first embodiment.
a, 10a bent portions 10b, 10b, elongated holes 10c, 10c
Is provided. This rectangular cardboard piece 10 is the first
It has the same function as the rectangular cardboard piece of the embodiment.

In this example, the trapezoidal flap bending portions 10b, 1
0b is folded back, so that the rectangular cardboard piece 10
The strength that regulates the position in the vertical direction can be increased. Therefore, even when a rectangular parallelepiped object such as an in-vehicle communication device body having an operation as a padding is not put in the space below the bracket 2 as in the first embodiment or when a thin member is put in, the rectangular cardboard piece 10 is used. The bracket 2 can be fixed.

[0021]

According to the cardboard cushioning material of the present invention,
The use of polystyrene foam does not affect the environment. Further, the cushioning material for regulating the position of the plate member can be made by cutting and raising a rectangular cardboard piece, and the material can be used efficiently.

Further, the cushioning material for regulating the position of the plate-like member is in the form of a thin plate, so that space can be saved and a function as a partition for the member can be provided. Further, the product is easily packed and taken out because the flap is easily generated.
