Description

[Detailed description of the invention] This invention is a ventilation fan that can be inserted between ventilation fan parts to fix the ventilation fan and parts inside the outer box when packing the ventilation fan and two or more parts in an outer box. This relates to cushioning materials.

Conventionally, this type of cushioning material made of cardboard was used by fitting a ventilation fan into it, storing it in an outer box, and then inserting several parts previously placed in parts boxes into the space in front and behind it.

However, such conventional products require a dedicated parts box for ventilation fan parts and require assembly work, resulting in high packaging costs.

The present invention has been made to eliminate such conventional drawbacks, and for this purpose, the present invention has a separation surface that is inserted into the upper flap of the cushioning material into the space between the parts to separate them. It is characterized by being integrally provided.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings. Figure 1 shows a cross-section of the packaging according to this invention, Figure 2 is a perspective view of the ventilation fan and parts inserted into the cushioning material for ventilation fans, and Figure 3 is an exploded view of the cushioning material for ventilation fans according to the invention. .

In the figure, 1 is a cushioning material for a ventilation fan made by cutting a sheet of cardboard or cardboard, 2 to 14 indicate each side, and 2, 4, 6, and 8 are 4 of the outer box 20.
Reinforcement surfaces 3 and 7 that double the corner portions are provided so as to face the side surfaces of the outer box 20, and rising surfaces 5 and 9 have the same spacing as the body frame of the ventilation fan 18, and 5 and 9 are reinforced surfaces of the outer box 1. An outer box width surface contact surface that is inserted so as to be in contact with the inside of the width surface and has the same dimensions as the inner diameter dimension of the outer box width surface, 10, 12
is connected to the upright surfaces 3 and 7, and is bent outward to extend between the ventilation fan 18 and the side surface of the outer box 20. 11 is an outer tensioning fixing surface that extends between the ventilation fan 18 and the side surface of the outer box 20, and 11 allows the shutter 19 fixed to the ventilation fan 18 to be easily inserted. An inner tensioning and fixing surface 13 is connected to the rising surface 5 and extends and supports and fixes the back surface of the front cover of the ventilation fan 18 by bending inward. An inner tensioning fixing surface 14 having the same dimensions as the inner diameter in the width plane and supporting and fixing the rear surface of the front cover of the ventilation fan 18 by bending it inward.
is connected to the outer tension fixing surface 12, and is bent downward from the C line at the center of the side surface to form parts 17 and 1, which will be described later.
15 is a wire that connects each surface, 16 is a stitching wire that secures the reinforcing surfaces 2, 4, 6, 8 and the outer box width contact surfaces 5, 9 in a double square manner. , 17, 17 are parts packed together with the ventilation fan 18 in the outer box 20.

With the above configuration, the cushioning material 1 cut out from cardboard is assembled by bending it from the designated wire 15, reinforcing surfaces 2, 4, 6, 8, outer box width contact surface 5,
9 with the stitching wire 16, and then attach the outer box 2.
0, the outer box 20 and the cushioning material are integrated. This outer box 20 is molded and bottomed, and the outer tension fixing surfaces 10 and 12 are bent outward. Then, the parts 17, 17 are inserted to the left and right using the separation surface 14 which is connected to the fixing surface A12. When inserting the ventilation fan 18 thereon, by folding the fixed surfaces 11 and 13 inward at the same time, the ventilation fan 18 will be placed inside the outer box 20 with the fixed surface 1 at the back of its front cover.
Supported and fixed by tensions 0, 11, 12, and 13. Since the two parts 17, 17 are separated by the separation surface 14 at the same time as they are fixed with a certain gap, they are protected from each other.

As described above, according to this invention, part of the cushioning material of the ventilation fan is used to buffer the parts,
It has a high cushioning effect, and since the part that was previously cut off is used as a separation surface between parts, materials can be used effectively, and a cushioning material for ventilation fans that can cushion parts without increasing cost can be provided.

In addition, since the back of the ventilation fan front cover is supported and fixed on the inner tension fixing surface that is bent inward from the contact surface of the outer box width surface, the ventilation fan body does not have any protruding objects such as shutters that are wider than the supported front cover. It also has the effect that it can be easily inserted and fixed even if it is damaged.
