Abstract

PURPOSE:To permit a ventilating fan to be supportably received in an outer case in a suspended condition by using the two cushioning plates made by bending the product stamped from a single kind of corrugated card-board sheet into a predetermined shape in contact with the ventilating fan. CONSTITUTION:The trough parts consisting of U-shaped front walls 2a and both side walls 2b and the two cushioning plates 2 consisting of horizontal flange parts 2c provided on the top of the trough part and bent in the directions opposite to the bent directions of the aforesaid side walls are placed in opposed relation in an outer case 1 in such a manner that each of the end parts of the horizontal flange parts 2c makes contact with the facing inner wall of the outer case 1 and, by using these two cushioning plates, a ventilating fan is supportably received in the outer case in a suspended condition. Since the two cushioning plates made by bending the products stamped from a single kind of corrugated cardboard sheet into the same shape and size are used in contact with the ventilating fan, the time required for the packaging is saved, the unit cost of the production is low and the storage is easy.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging device for a ventilation fan having a cylindrical main body and a grille projecting outward from the top of the main body.

0002

2. Description of the Related Art FIG. 7 is a perspective view showing a conventional ventilation fan packaging device disclosed in, for example, Japanese Utility Model Publication No. 57-20538. C) is stored in a suspended state, the whole thing is tightened with a band (D), and it is stored inside the outer box.

0003

[Problems to be Solved by the Invention] As described above, in the conventional packaging device, four sheets of sheet material punched in advance into a predetermined shape are used in combination in parallel grids, which requires time and effort to assemble, resulting in reduced productivity. The problem was that the quality was poor and the price was high.

[0004] This invention was made to solve the above-mentioned problems, and consists of two buffer plates made by bending a single type of cardboard sheet die-cut product into a predetermined shape, and placing them in contact with a ventilation fan. The purpose is to store and support the ventilation fan in an outer box in a suspended state just by using it.

[0005]

[Means for Solving the Problems] A packaging device for a ventilation fan according to a first aspect of the present invention includes a gutter-shaped part bent in a U-shape, and a gutter-shaped part provided in series at the top of the gutter-shaped part, and a bent part of the gutter-shaped part. A buffer plate consisting of a horizontal flange bent in the opposite direction.
They are housed in an opposing state in the outer box so that the tip of each horizontal flange is in contact with the opposing inner wall surface of the outer box. The shaped main body is inserted, and its top grill is placed on each of the horizontal flanges so that the ventilation fan is suspended in midair.

[0006] Further, directly below the horizontal flange of each of the above-mentioned buffer plates,
An end reinforcing piece may be formed that is continuous with this and stands flush with the front wall of the U-shaped trough-like portion.

[0007] In the ventilation fan packaging device according to the second aspect of the present invention, an inner bag is attached to the top of each of the two buffer plates that are in contact with the opposing surfaces of the cylindrical main body and are housed in an opposing state in the outer box. The peripheral edge of the grill of the ventilation fan is held from the outside, and the grill protection walls, whose outer end surfaces are in contact with the inner wall surface of the outer box, are bent in a series, and the ventilation fan is suspended in the air using both of these buffer plates. It is stored and supported inside the box.

[0008]

[Operation] In both the first and second aspects of the present invention, the ventilation fan is supported in a suspended state within the outer box by using the two buffer plates bent into the specific shape mentioned above in contact with the ventilation fan. Ru. In particular, in the second aspect of the invention, the grill of the ventilation fan can be protected at the same time. Furthermore, in the first invention, by forming the end reinforcing piece directly under the horizontal flange of the buffer plate, the strength against the load applied to the horizontal flange is improved.

[0009]

[Example] Example 1. 1 to 3 show an embodiment of the first invention of the present invention, and in these figures, (1) is an outer box that houses a ventilation fan, and (2) is a box that is opposed to each other inside this outer box (1). This is a buffer board made of a punched and folded cardboard sheet of the same shape and size as that stored in the box.This buffer board is made by punching and folding a cardboard sheet in one process as shown in Figure 3, as shown in Figure 2. Used by folding. That is, (2a) in the figure is the front wall that comes into contact with the side surface of the cylindrical main body (3) of the ventilation fan,
(2b) is a cylindrical main body (3) which is bent toward the opposite side in FIG.
), (2c) is the top of the front wall (2a) that is bent toward the front in the figure with the upper bending line C connecting the cut groove B and the upper bending line C between them as a boundary. The grill (4) of the ventilation fan is placed on top of the horizontal flange when in use. In summary, the above buffer plate (2)
It consists of a U-shaped gutter-like part consisting of a front piece (2a) and both side walls (2b), and a horizontal collar part (2c) at the top. (5) is a band that tightens the gutter-like part of each buffer plate (2) together with the cylindrical main body (3) of the ventilation fan, and (6) is a bottom buffer sheet laid on the inner bottom of the outer box (1). , (7) is an upper buffer sheet placed on the grille (4), and (8) is a sealing tape attached to the open line portion of the outer box (1). Note that the band (5) may be replaced with adhesive tape, or the lower end surface of each buffer plate (2) may be covered with a bottom buffer sheet (6).
It is also possible to omit their use by locking them.

Example 2. Fig. 4 shows another embodiment of the buffer plate shown in Fig. 3, in which a front wall (2a) of a U-shaped gutter-like part is provided directly below the upper horizontal brim part (2c) and continuous with this. The end reinforcing piece (2d) of the horizontal flange (2c) rising flush from the
It is characterized in that it is formed by an intermediate bending line D.

Example 3. 5 and 6 show an embodiment of the second invention of this invention,
In this case, on both sides of the front wall (2a), the side walls (2
b), and above the bending line C of the horizontal flange (2c), a ventilation fan grill protection wall (2e) defined by two bending guides D and E is formed in series. The points are distinctive.

That is, each buffer plate (2) is in contact with the opposing surface of the cylindrical main body (3) and is housed in the outer box (1) in an opposing state.
), there is a horizontal flange on the top of the grille protection chamber (2e) which holds the peripheral edge of the grille (4) of the interior ventilation fan from the outside and whose outer end surfaces are in contact with the inner wall surface of the outer box (1). (2
c), and these parts are held together by the peripheral edge of the grille (4) and are tightened with, for example, a band (10) as shown in Figure 6. In state 6, the ventilation fan is housed in the outer box (1) as shown in Figure 1. Note that the use of the above band can also be omitted by suppressing it with the upper buffer sheet (7).

[0013]

[Effects of the Invention] Since the ventilation fan packaging devices of the first and second aspects of the present invention are constructed as described above, two buffer plates bent to the same shape and size can be brought into contact with the ventilation fan. By simply using the ventilation fan, the ventilation fan can be stored and supported in a suspended state within the outer box, and especially in the case of the second embodiment, it is also possible to protect the grille. Furthermore, by forming the end reinforcing piece directly under the horizontal flange of the buffer plate of the first invention, there is also an effect that the strength against the load applied to the horizontal flange is improved.
