DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to storage of a ventilation fan and
The present invention relates to a ventilation fan packaging device for preventing damage to a ventilation fan during transportation.

[0002]

2. Description of the Related Art In recent years, there has been a demand for a ventilating fan packaging device that has high workability in packing and unpacking, has a simple structure, and sufficiently absorbs a load during storage and a shock during transportation.

As shown in FIG. 4, a conventional ventilation fan packaging apparatus of this type houses a box-shaped ventilation fan 101 manufactured in a factory in an outer box 102, and receives the ventilation fan 101 by an external impact. To prevent the outer box 102 from being moved or damaged, and to prevent the outer box 102 from being deformed by the load when being stacked in multiple layers. The formed buffer pad 103 was inserted.

[0004]

In such a conventional ventilating fan packaging apparatus, the buffer pad 103 is formed of styrofoam, and a molding die is required.
There have been problems such as an increase in manufacturing cost and generation of harmful gases that cause pollution during incineration and disposal after use.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and sufficiently absorbs the load during storage and the impact during transportation, which are the original purposes of the ventilation fan packaging device, without impairing the protection of the ventilation fan after use. An object of the present invention is to provide an inexpensive ventilation fan packaging device that does not cause pollution in incineration disposal.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an outer box for accommodating a box-shaped ventilation fan having an opening on one side and a flange protruding outward on the outer periphery of the opening. Along with providing a reinforcing portion that fits on the inner periphery of the outer box by vertically bending the four sides of the square plate material as bending lines, and providing a square hole in the center, and from each corner of this hole, A diagonally outward cut is made and bent vertically downward to provide a holding part that abuts on the inner periphery of the opening of the ventilation fan, and a flat part connecting the reinforcing part and the holding part is provided on the upper surface of the flange part. A buffer pad as an abutting holding plate; and an inner box fitted on the inner periphery of the holding portion of the buffer pad and preventing the ventilation fan from moving in the vertical direction, the outer box, the buffer pad, and the inner box. Box is made of rigid paper such as cardboard And it is obtained by the configuration of the packaging apparatus of the ventilation fan.

[0007]

According to the present invention, the ventilation fan is positioned horizontally by the buffer pad and the inner box fitted on the inner periphery of the holding portion of the buffer pad, and vertically by the inner box. The ventilation pad is moved and damaged by shock from the outside, and the shock absorber pad and inner box are buffered and fall from the top surface where the flange of the ventilation fan is easily deformed. The damping pad's holding plate cushions the damper from being damaged. Further, since the outer box, the buffer pad, and the inner box are formed of rigid paper such as cardboard, styrofoam is not required.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

As shown in the figure, a box-shaped ventilation fan 3 having an opening on one surface serving as a main body suction opening and having an outwardly protruding flange 2 on the outer periphery of the opening 1 is made of corrugated cardboard. It is stored inside the formed outer box 4 with the opening 1 facing upward,
At this time, it is held and fixed by a below-described buffer pad 5 and an inner box 6 inserted between the upper part of the ventilation fan 3 and the lower surface of the upper plate 4a of the outer box 4. The buffer pad 5 is formed by vertically bending the four side portions 7 of a quadrangle corrugated cardboard as a folding line to form a reinforcing portion 8, and the upper end of the reinforcing portion 8 is brought into contact with the lower surface of the upper plate 4a of the outer box 4. At the same time, the outer periphery is fitted to the inner periphery of the outer box 4. In addition, buffer pad 5
Has a rectangular hole 9 in the center, cuts 10 diagonally outward from each corner of the hole 9, and vertically folds the opening 9 so that the opening end of the hole 9 faces downward.
Is formed. Then, the holding portion 11 is fitted to the inner periphery of the opening 1 of the ventilation fan 3, and the reinforcing portion 8 and the holding portion 1 are fitted.
The lower surface of the pressing plate 12, which is a flat portion connecting with 1, is connected to the ventilation fan 3
The ventilation fan 3 is held and fixed by pressing it against the flange portion 2. On the other hand, the inner box 6 is formed in the shape of a box whose upper surface is opened by corrugated paper, and its upper end is brought into contact with the lower surface of the upper plate 4a of the outer box 4 and the lower surface is pressed against the central portion of the ventilation fan 3. The vertical movement of the ventilation fan 3 is prevented, and the outer periphery is fitted to the inner periphery of the opening 1 of the ventilation fan 3 with a holding portion 11 interposed therebetween to hold and fix the ventilation fan 3 in the horizontal direction.

In the above configuration, the reinforcing portion 8 of the buffer pad 5 and the inner box 6 prevent the outer box 4 from being deformed by the load, and the ventilation fan 3
Can be buffered. In addition, the holding portion 11 of the buffer pad 5 holding the ventilation fan 3 moves due to the impact in the front, rear, left and right directions, and the inner box 6 prevents the movement of the ventilation fan 3 and the shock applied to the ventilation fan 3 is buffered. can do. Further, the ventilation fan 3 drops from the top surface where the easily deformable flange portion 2 is located, and the flange portion 2
Collides with the inner wall of the outer box 4 and deforms.
The entire lower surface of the holding plate 12 can be blocked, and a drop impact applied to the flange portion 2 can be buffered. And because it does not use styrofoam, it can be reused after use, and it can be disposed of without generating harmful gases that cause pollution even if it is incinerated. Since only a die is required, the cost of a mold per unit can be reduced.

As described above, according to the ventilation fan packaging apparatus of the present invention, the shock absorbing pad 3 and the inner box 6 cushion the movement or damage of the ventilation fan 3 from the outside,
Can be protected. Then, after use, it can be incinerated and disposed of without regenerating or causing pollution, and the unit price per unit can be reduced.

[0012]

As is apparent from the above description of the embodiment, according to the present invention, the load during storage and the shock during transportation are sufficiently buffered by simple members such as the buffer pad and the inner box to protect the ventilation fan. In addition, since the outer box, the buffer pad, and the inner box are formed of corrugated cardboard, it is possible to provide an inexpensive ventilating fan packaging device that can be reused after use or disposed of by incineration without risk of pollution. .
