Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a packaging device for packaging equipment having legs by placing it on a bottom cushioning body.

Conventionally, in this type of packaging device, an escape recess for storing the legs is formed on the upper surface of the bottom cushioning body, and when the device is placed on the bottom cushioning body, the legs are loosely inserted into the relief recess. A type is provided in which the load of the equipment is received on the top surface of the bottom shock absorber. However, with the above configuration, when a strong impact force is applied to the device, the load of the device is concentrated on the opening edge of the relief recess on the top surface of the bottom shock absorber, and in extreme cases, this portion may be damaged. Therefore, there was a problem that a sufficient buffering effect could not be obtained.

The present invention was developed in view of the above circumstances, and its purpose is to form the recess for storing legs provided in the bottom cushioning body into a bottomed shape that is deeper than the protruding length of the legs, and to increase the width at the bottom. It is formed into a tapered shape that gradually becomes narrower toward the bottom so that it is smaller than that of the legs, and the bottom of the device is always placed above the top of the bottom cushioning body with the bottom of the legs rising above the bottom of the recess. It is an object of the present invention to provide a packaging device which can increase the cushioning effect by gradually receiving the impact load acting on the bottom cushioning body from the equipment.

An embodiment in which the present invention is applied to, for example, a packaging device for a washing machine will be described below with reference to the drawings. Reference numeral 1 denotes a washing machine as a device, and legs 3 on which rollers 2 are rotatably provided protrude from the four corners of the bottom of the washing machine. Reference numeral 4 denotes a base of a packaging device for packaging the washing machine 1, and this is formed, for example, from cardboard into a flat rectangular box shape with an open top surface. Reference numeral 5 denotes four bottom cushioning bodies made of, for example, styrofoam and arranged at the four corners of the base 4, and a protective wall 6 is integrally extended above the two sides touching the side walls of the base 4. At the same time, a bottomed recess 7 for storing the legs 3 is formed in the upper surface. As shown in FIG. 2, the depth A of the recess 7 is set larger than the protruding length a of the leg 3, and the opening dimension at the upper part is larger than the cross-sectional external dimension at the upper part of the leg 3. The width of the leg 3 is also large, and the width tapers downward so that the width dimension (width dimension B) between the inner wall surfaces at the bottom is smaller than the width dimension (width dimension b) at the lower end of the leg 3. It is formed. Reference numeral 8 denotes a groove for escaping the roller 2 which is further recessed in the bottom surface of the recess 7, and in this embodiment, its depth C is larger than the protruding length c of the roller 2 from the leg 3. . Therefore, when the washing machine 1 is placed on the four bottom cushioning bodies 5 with the legs 3 housed in the recesses 7, the washing machine 1 is placed with the legs 3 floating above the bottom of the recesses 7. The bottom surface is supported by the upper surface of the bottom buffer 5, and the outer circumferential wall of the bottom of the leg 3 comes into contact with the inner wall surface of the recess 7. Reference numeral 9 denotes an upper box body, which is in the shape of a rectangular box with an open bottom surface in contrast to the base 4, and is placed over the top surface of the washing machine 1 placed on the bottom cushion 5 of the base 4. The washing machine 1 is wrapped together with the base 4 by tightening with a band (not shown).

In the case where the washing machine 1 is packaged with the above structure, if a downward impact force is applied to the washing machine 1 for some reason during handling during transportation, the bottom shock absorber 5 is compressed by the impact force. It is received by the upper surface of the bottom buffer 5 from the bottom. When a stronger impact force is applied, the bottom buffer 5 is first compressed as described above, and as a result, the legs 3 enter deeper into the recess 7, causing the bottom of the legs 3 to come into frictional contact with the inner surface of the recess 7. Since it is strongly press-fitted while still being strong, it can be received not only by the upper surface of the bottom cushioning body 5 but also by the inner wall surface of the recessed portion 7. Further, when a stronger impact force is applied, in addition to the above, the bottom of the leg 3 comes into contact with the bottom of the recess 7 and compresses it, thereby providing a buffer.

In this embodiment, when an impact force is applied to the washing machine 1, this force is first applied to the upper surface of the bottom buffer 5, then to the inner wall surface of the recess 7, and then to the recess 7. Since the bottom surface cushions the impact in stages, even a fairly strong impact force can be attenuated in stages, resulting in an excellent cushioning effect. Moreover, in this embodiment, the depth dimension C of the groove 8 is set to be larger than the protrusion length c of the roller 2, so even when the bottom of the leg 3 comes into contact with the bottom surface of the recess 7, the lower end of the roller 2 Since it is floating above the bottom surface of the groove 8 and has a bearing etc., it is possible to prevent impact force from acting on the roller 2, which is mechanically weaker than other parts, as much as possible.

In the above embodiment, the bottom of the leg 3 is in contact with the inner wall surface of the recess 7 when the washing machine 1 is placed on the bottom cushion 5, but the present invention is not limited to this. In the normal mounting state, the legs 3 are in the recess 7.
The bottom part of the leg 3 comes into contact with the inner wall surface of the recess 7 and is press-fitted into the recess 7 only when an impact force is applied thereto and the bottom buffer body 5 is compressed without touching the inner wall surface of the leg 3. Also, as mentioned above, it is possible to exhibit an excellent buffering effect. Furthermore, the inner wall surface of the recess 7 does not necessarily have to be smoothly tapered, but may be made substantially tapered by decreasing the width stepwise downward.

As described above, the present invention is such that the recess for storing the legs of the bottom cushioning body is formed into a bottomed shape that is deeper than the protruding length of the legs, and the recesses are formed downward so that the width at the bottom is smaller than that of the legs. The legs are formed into a tapered shape that gradually becomes narrower toward The device is characterized by the fact that the bottom of the device is received by the top surface of the bottom cushioning body while the device is lifted up from the bottom of the recess, and as a result, a strong impact force is applied to the packaged device. It is possible to provide a packaging device that can absorb this in stages even if it occurs, exert an excellent cushioning effect, and sufficiently protect the equipment.

[Brief explanation of drawings]

Claims (1)

[Scope of utility model registration request] In a device in which a device having legs at the bottom is placed on a bottom cushioning body having a recess for storing the legs, the recess of the bottom cushioning body is deeper than the protruding length of the legs. Formed in a bottom shape, the bottom of the leg is normally raised above the bottom of the recess to receive the bottom of the device on the top of the bottom buffer;
The concave portion of the bottom buffer is configured such that the opening size at the top is larger than the outer diameter across the upper part of the leg, and the width across the inner wall surfaces at the bottom is larger than the outer diameter across the bottom at the lower end of the leg. The packaging device is characterized in that the legs are formed in a tapered shape that gradually becomes narrower toward the bottom so that the lower end portions of the legs come into contact with the inner wall surface of the recess.
