[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device having a flange at one end, for example, a packing device for a ventilation fan or a lighting device.

[0002]

2. Description of the Related Art As a technique prior to the present invention, the actual technology of Shoko 53
There is a packing device described in Japanese Patent No. 539. This packing device sandwiches the equipment from both sides in a sandwich shape with a cushioning body such as styrofoam, and encloses this outer periphery with a sheet-shaped cardboard paper outer casing, in which a groove is formed on the outer periphery of the cushioning body, The end portion of the outer package is bent and inserted into this groove with a slight press fit. Therefore, the external shape of the packing device is a rectangular parallelepiped.

Since such a packing device has a rectangular parallelepiped shape, a large space is required for transportation and storage in a warehouse, and transportation and storage costs are high.
Further, although the device has a collar portion, a large amount of expanded polystyrene is required to form a rectangular parallelepiped part in the portion excluding the collar portion, and the material is wasted.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and aims to reduce the load capacity during transportation and the storage capacity during storage, and to reduce the material forming the buffer body. An object of the present invention is to provide a packaging device that can be used.

[0005]

DISCLOSURE OF THE INVENTION The present invention provides a pair of cushioning bodies each having a tubular device body having a flange portion formed at one end and a fitting recess formed on one side surface for fitting the collar portion and the device body. It is sandwiched between the cushioning bodies and surrounded by a cylindrical outer casing, and both side surfaces adjacent to one side surface of the cushioning body having the fitting recess are provided on the device body and the protrusion corresponding to the flange portion. Correspondingly, it is configured with a concave step surface that is recessed from the protrusion, and the length of the concave step surface along the axial direction of the tubular device body is the same as or longer than that of the protrusion, and the exterior body is formed. The cushioning body is surrounded along the protrusions and the concave step surfaces on both side surfaces.

[0006]

According to the present invention, since the portion corresponding to the device main body on both side surfaces adjacent to the one side surface having the fitting concave portion of the shock absorber is the concave step surface, the material of the shock absorber can be saved. When transporting or storing multiple packing devices of this type, the overall dimensions can be made compact by arranging the projections provided on the buffer body of one packing device so as to be combined with the concave step surfaces of the other packing device. Become.

[Example] For a ventilation fan as the equipment to be packed,
A description will be given based on the figure. The ventilation fan 1 includes a rectangular tubular ventilation fan main body 2 formed by bending and joining sheet metal, and a front panel 3 mounted on a mounting flange portion formed on one side of the main body 2. On the other side of the main body 2, a shutter plate is openably and closably mounted, and an electric motor is mounted inside. A blower blade is attached to the electric motor. The front panel 3 is molded of synthetic resin to form a wind tunnel surrounding the blower blades. The periphery of the front panel 3 projects from the main body 2 to form a collar portion 4.

A pair of buffer bodies 5, 6 for sandwiching the ventilation fan 1 from both sides (only one buffer body 5 is shown in FIGS. 1 and 2, but both buffer bodies 5 are shown in FIG. 5 as another embodiment). ,
6 is shown in the drawing) is molded with polystyrene foam. A deep and wide fitting concave portion 7 into which the collar portion 4 is fitted and a shallow and narrow fitting concave portion 8 into which the main body 2 is fitted are formed on the opposite side surfaces of the buffer bodies 5 and 6. is doing. (Fig. 2
(See FIG. 5 and FIG. 5) Both side surfaces adjacent to one side surface on which the fitting concave portions 7 and 8 of the buffer bodies 5 and 6 are formed are provided with protrusions 10 corresponding to the collar portion 4.
And a concave step surface 9 corresponding to the main body 2 and retracted from the protrusion 10.

In the state where the ventilation fan 1 is sandwiched between the buffer bodies 5 and 6, the ventilation fan 1 of the buffer bodies 5 and 6 is shown in FIG.
A is the length along the axial direction of A, B is the length of the concave step surface 9, and W is the depth. The length B is equal to or larger than half of A. In other words, the length B of the concave step surface 9 is set to be equal to or longer than the length of the protrusion 10. The depth W is the same as the projecting dimension of the collar portion 4 when the thickness of each portion of the buffer bodies 5 and 6 is made uniform.

The exterior body 11 is a protrusion 10 on both side surfaces of the buffer bodies 5 and 6.
And a tube having a T-shaped cross section along the concave step surface 9,
With the ventilation fan 1 sandwiched between the buffer bodies 5 and 6, the space between the buffer bodies is surrounded by the exterior body 11.

After being surrounded by the outer casing 11, the tightening band 12 is wound as shown in FIG. 1, whereby the ventilation fan 1, the buffer bodies 5 and 6 and the outer casing 11 can be integrated. In this state, the projections 10 of the buffer bodies 5 and 6 are projected, and the appearance becomes T-shaped as shown in the figure.

Next, the difference from the conventional technique during transportation and storage will be described with reference to FIG. The solid line in FIG. 3 shows the case of the present invention, in which the projecting portion 10 of one packing device is stacked side by side so as to be combined with the concave step surface 9 of the other packing device.
By doing this, compared to the conventional one shown by the one-dot chain line,
When three packing devices are arranged as shown in the drawing, the size can be reduced by the dimension of 2W, which is twice the depth W of the concave step surface 9. Also, the combination makes it difficult for the load to collapse.

FIGS. 4 and 5 show another embodiment which is more convenient to use, in which the tightening band 12 is wound around the concave step surface 9 so that the outer casing 11 can be securely held in the T-shape. It will be In addition, a notch 13 is formed at the end of the exterior body 11 around which the tightening band 12 is wound, and a groove 14 is formed in each of the shock absorbers 5 and 6, and the tightening band 12 is wound around the notch 13 and the groove 14. While surely blocking the movement of the attached band 12,
The thickness of the tightening band 12 reduces the gap during loading. Further, a concave portion 15 into which a finger is inserted is formed in a portion around which the tightening band 12 of the buffer bodies 5 and 6 is wound, so that the tightening band 12 can be used as a handle.

[0014]

As described above, according to the present invention, since the portions corresponding to the main body of the device on both side surfaces adjacent to the one end portion having the fitting concave portion of the cushioning body are the concave step surfaces, the material of the cushioning body can be greatly reduced. In addition, when storing or transporting multiple packing devices, the packing device has a T-shape, so the projection provided on one buffer body should be combined with the concave step surface of the other buffer body. By arranging in, the overall size becomes compact and the storage and transportation costs can be reduced.
