Description

[Detailed description of the invention] This invention relates to a packaging frame for preventing soiling and damage to ventilation fans during storage or transportation.

Conventionally, ventilation fans produced in factories are housed in an outer box, and in order to prevent the ventilation fan from moving within the outer box, it is necessary to fill the space between the outer box and the ventilation fan with a packaging frame. In this method, cardboard materials were cut into appropriate dimensions, and these were assembled and bonded to form a single body, or foamed resin was used.

However, the conventional packaging frame configured in this way.

The manufacturing cost is high, and the process of disposing of the used layer is time-consuming and causes pollution.

This invention aims to improve the above-mentioned drawbacks.

A total of four slits are provided at a predetermined length in a direction perpendicular to the reference line y at the inner position provided, and these four slits 2
a denotes an inner piece 8a, an outer piece 9a, and a flap 10a, which will be described later.
The length of each slit is formed to be slightly longer toward the reference line y side than the length of the slit 2 of the first holder 11.

4a is a first fold formed by connecting the outer ends of two sets of slits 2a provided parallel to each other on both sides of the reference line y, and 5a is a reference line y between the two sets of slits 2a. The second folds 3b are formed on the sides, the third folds 3b are formed from the ends of the four slits 2a on the reference line y side to the edges 1c in the longitudinal direction, and the 5a are parallel to the third folds 3b. 10a is a flap formed on the outside of the first fold 4a; The outer piece 8a is surrounded by a pair of slits 2a, a first fold 4a and a second fold 5a, and 8a is a slit 2a and a third fold 3b.

The longitudinal edge 1C of the second holder base paper 1b and the fourth
The inner piece 7 is surrounded by the folds 6a, and the bottom piece 7 is surrounded by the second folds 5a on both sides of the reference line y and the portion of the slit 2a closer to the reference line y. It consists of

Furthermore, this second holder 12 has its inner piece 8a, outer piece 9a, and flap 10a, respectively, in the same way as the first holder 11, with the inner piece 8a standing upright inward through the third fold 3b, and the outer piece 9a is made to stand upright inward through the second fold 5a, and the flap 10a is horizontally bent outward through the first fold 4a, resulting in the shape shown in FIG. 3.

And as shown in Figure 3. Bottom piece 7 of first holder 11
The two holders 11.12 are superimposed so that the back surfaces of the bottom pieces 7a of the second holder 12 are in contact with each other, and the bottom pieces 7, 7a are joined to the flaps 10.10a by adhesive or the like to form the packaging frame body. It consists of 13.

FIG. 4 is a developed view of the protection plate 14 for protecting the front part of the ventilation fan housed in the outer box, which is bent from the fold line 14a and has double sides to increase mechanical strength.

FIG. 5 shows the housing state of the ventilation fan in the outer box. In FIG. 1, the same reference numerals as in FIGS. 1 to 4 indicate the same or corresponding parts, and 15 is the outer box.

15a is the lid of the outer box.

16 is a ventilation fan. As shown in the figure, the flap 10a of the packaging frame main body 13 is brought into close contact with the stepped portion 16a of the ventilation fan 16,
The left and right sides of the square rear part 16b of the ventilation fan 16 are attached to the packaging frame body 13.
