Description

[Detailed Description of the Invention] The present invention relates to a packaging device for a ventilation fan, and provides a packaging device that has a simple structure and reduces the influence of external force on the ventilation fan housed in an outer box.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

Reference numeral 1 denotes a ventilation fan, which is composed of a rectangular cylindrical main body 2 and a flange 3 located at the front of the main body 2 and whose peripheral edge protrudes from the main body.

Although not shown in the drawings, a fan motor is fixed inside the main body 2 via a mounting frame.

Further, the flange portion 3 is integrally formed with a lattice-shaped wind tunnel located with a gap between it and the outer periphery of the fan motor.

Reference numeral 4 designates an outer box in which the ventilation fan 1 held by a buffer body 5 is housed.

The buffer body 5 is formed by bending a sheet of corrugated paper.

A substantially H-shaped notch 6 is formed in the center of the corrugated paperboard to form a side holding portion 7.

The buffer body 5 includes an annular frame portion 8 formed by bending the side surface holding portion 7, a spacing piece 9 rising from the opposing outer edge of the frame portion 8, and a collar portion extending from the spacing piece 9. 3 and a cover portion 10 that covers the upper surface.

The annular frame portion 8 has its outer peripheral edge in contact with the inner surface of the outer box 4.

The edge of the central opening 11 of the frame portion 8 abuts against the main body 2 .

The side surface holding portion 7 is in contact with the side surface of the main body 2, and
Its edge abuts the inner surface of the outer box 4.

The spacing piece 9 comes into contact with the inner surface of the outer box 4 and extends to the bent portion of the outer box 4, and forms a gap between the spacing piece 9 and the side surface of the flange 3.

The cover portion 10 extends in contact with the upper surface of the flange 3 and the inner surface of the outer box 4, and its edges abut each other at the center of the upper surface of the flange 3.

Therefore, the ventilation fan 1 held by the buffer body 5 is placed in the outer box 4.
When the ventilating fan 1 is housed in the ventilating fan 1, the external force applied to the outer box 4 is absorbed by the side surface holding part 7, the annular frame part 8, and the cover part 10.degree. 10, so that no large force is applied to the ventilation fan 1.

Further, the flange portion 3 includes the annular frame portion 8 and the double force bar portion 10.
．． Since the edges of the double-edged bar portions 10 are in contact with each other, the force applied to the flange portion 3 is smoothly absorbed by the upper and lower surfaces of the flange portion 3.

Furthermore, since the ends of each part of the buffer body 5 are in contact with the inner surface of the outer case 4, it has the effect of functioning as a reinforcing material for the outer case 4.

Figures 6 and 7 and Figures 8 and 9 show other embodiments of the present invention.

In the embodiment shown in FIGS. 6 and 7, the lower part of the side holding part 7 in the above-mentioned embodiment is bent to form a foot part 12 extending along the inner surface of the outer box 4 to the bent part of the outer box. It was established.

Therefore, when the buffer body 5 holding the ventilation fan 1 is inserted into the outer box 4, the side holding portions 7 tend to move away from the main body 2, but the foot portions 12 come into contact with the bent portions of the outer box. Therefore, the side surface holding portion 7 always comes into contact with the side surface of the main body 2 and holds the main body with a good cushioning effect.

The embodiment shown in FIGS. 8 and 9 has a U-shaped cut 13 extending from the cover part 10 to the outer edge of the annular frame part 8 in the cover part 10 and the spacing piece 9 in the first embodiment described. , with which a raised piece 14 is formed.

The cut and raised piece 14 is bent in the same direction as the side holding part 7 in an oval shape so as to follow the bent part of the outer box 4,
Its edge is brought into contact with the lower part of the holding part 7.

Therefore, even if the side surface holding portion 7 tries to spread out from the side surface of the main body 2, the movement is prevented by the cut and raised pieces 13, so that the side surface holding portion 7 always comes into contact with the side surface of the main body 2 and provides a good buffering effect. Hold the ventilation fan body.

As described above, the present invention includes a buffer body for holding a ventilation fan, which has an annular frame portion that has an opening into which the ventilation fan body fits and contacts the lower surface of the ventilation fan flange and the inner surface of the outer box, and a buffer body that hangs down from the inner edge of the frame portion. a side holding part whose lower edge abuts the outer box; and a side holding part which covers the upper surface of the flange part from the opposite outer edge of the frame part through a spacer piece having a height matching the thickness of the flange part, and whose edges abut each other. Since the parts of the cover that are in contact with each other are formed continuously and integrally, the number of parts is small, which simplifies the packaging process, and the external force applied to the outer box is smoothly absorbed by each part of the shock absorber. A large amount of force is not applied to the ventilation fan.

Further, the flange portion is covered with the annular frame portion and a portion of the force bars, and the edges of the portions of the force bars are in contact with each other, so that the external force that is about to act on the flange portion is It is absorbed by the frame part and a part of the cover, and the flange part is held with better cushioning effect, which has great practical effects.
