BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging device such as an air conditioner, and more particularly to a packaging device such as an outdoor unit whose main body is made of synthetic resin.

[0002]

2. Description of the Related Art For packaging an outdoor unit of an air conditioner, for example, a box-shaped cardboard bottom plate 1 as shown in FIG. 5 and a lower portion arranged on the left and right inside the bottom plate 1 to support a device body 3 are provided. The cushioning body 2, a pair of upper cushioning bodies 4 formed in a U-shape to cover the upper and left sides of the upper portion of the device body 3 to protect the corners from impacts, and the like. A top plate 5 made of cardboard and a corner reinforcement having an L-shaped cross section in which the lower part is inserted between the inner corner surface of the bottom plate 1 and the lower cushioning member 2 and the upper outer surface is brought into contact with the inner corner surface of the top plate 5. Using the plate 6, a band (not shown) is wound on the outside and fastened. However, in the conventional shape of the upper cushioning member 4, as shown in FIG. 5, the portion in contact with the upper corner portion of the device body 3 hits the flat portion on the top surface. By the way, as for the outdoor unit, there is a movement to make the device body 3 a synthetic resin as the appearance and weight of the outdoor unit are reduced. AE as material
There are synthetic resins called S, AAS, PP, etc., but PP is attracting attention because it is cheaper. But,
PP is weak against heat, and when the device body 3 is shaped as shown in FIG. 5 and a heat-resistant compression test (test assuming storage in a warehouse for a long period on a hot summer day) is performed, the device body is The vicinity of the center of the upper end face of No. 3 becomes wavy, which may cause a problem in appearance. As one means for eliminating this kind of deformation, it is effective to change the shape of the upper buffer body 4 from the current U-shape to a box shape that covers the entire upper part of the device main body 3, but this upper buffer body 4 has Foamed resin (HPS) is used, and if it is left unused after use, it may cause environmental problems, so the amount of use tends to be reduced. If the upper buffer body 4 is made larger, it goes against the environmental problems.

[0003]

In view of the above problems, it is an object of the present invention to provide a packing device such as an air conditioner which can solve the above problems without going against the improvement of environmental problems. .

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has a box-shaped bottom plate made of cardboard, and lower cushioning members arranged on the left and right inside the bottom plate. A device main body having an upper corner portion curved on the lower cushion, an upper cushion disposed on the left and right of the device main body in contact with a curved surface of the upper corner, and a bottom plate A cross-section L inserted between the inner corner surface and the lower shock absorber so that the upper inner surface abuts the outer corner surface of the upper impact body.
A corner reinforcing plate, a box-shaped top plate made of cardboard that covers the upper cushioning body, and a packing device in which a band is fastened to the outside of the top and bottom plates. The inside of the device is cut into a portion that comes into contact with the top surface of the device body. In addition, the upper buffer body is formed into a pair of U-shapes. Also,
The cutout portion of the upper buffer body is formed to be curved. Further, the cutout portion of the upper buffer body is formed in an L shape.

[0005]

With the above construction, since the upper corners of the device body are pressed by the upper shock absorbers and the upper shock absorbers are pressed by the top plate, the top surface of the device main body and its periphery are strengthened. Therefore, even if a heat resistant compression test or the like is performed, the top surface of the device body and its surroundings can be protected, and deformation of the top surface can be prevented.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows an outdoor unit of an air conditioner and a packing device therefor. 1 is a box-shaped bottom plate made of corrugated cardboard, 2 is a bottom cushion made of foam resin arranged inside the bottom plate 1 on the left and right sides. Body, 3 is an outdoor unit whose main body is made of synthetic resin,
Reference numeral 4 denotes a foamed resin upper shock absorber that protects the upper left and right corners of the outdoor unit 3 from shocks and the like, 5 denotes a box-shaped cardboard top plate that covers the upper shock absorber 4 from above, and 6 denotes the lower part. The corner reinforcing plate is a corrugated cardboard having an L-shaped cross section, which is inserted between the inner corner surface of the bottom plate 1 and the lower shock absorber 2 so that the upper inner surface abuts the outer corner surface of the upper shock absorber 4. The upper cushioning body 4 is provided with a curved cutout portion 7 which is fitted to the curved surface of the upper corner of the outdoor unit 3, and is formed in a pair of U-shapes.

FIG. 2 shows a portion where the upper corners of the outdoor unit 3 and the upper shock absorber 4 are in contact with each other, which is a feature of this embodiment. FIG. The state where one side of the cushioning body 4 is covered is shown, and FIG. 7B shows the cross section of the abutting portion. (B) As shown in the figure, the upper shock absorber 4 comes into contact with only the curved surface of the upper corner of the outdoor unit 3 by the notch 7, and even if a load is applied from the upper part of the upper shock absorber 4, It is formed so as not to hit the flat portion on the top surface. Further, FIG. 3 shows a cross-sectional shape of an upper cushioning body 4 showing another embodiment. An L-shaped step surface is provided inside the upper cushioning body 4 and the outdoor unit 3 of the outdoor unit 3 is provided in the same manner as in the above embodiment. It is formed so as not to hit the flat portion on the top surface. FIG.
Is a side view and a front view of the packed state of the outdoor unit with a partial cross section, and the upper corners of the outdoor unit 3 are the upper shock absorbers 4.
You can see that it is being held down by. A band 8 is wound and fastened to the outside of the packing device including the bottom plate 1 and the top plate 5.

[0008]

According to the packing apparatus described above, since the top surface of the main body of the outdoor unit, which is the object to be packed, is pressed by only the curved surfaces of the upper corners by the upper cushion, the main body is made of synthetic resin. Even though it does not deform during storage,
Further, since the upper buffer body is formed in a U-shape, it contributes to the prevention of environmental damage to some extent.
