The Also, the left and right leg engaging pieces 3c are joined to the engaging grooves of the left and right leg slits 2a in the left and right leg inner pieces 3d at the ends of the left and right leg inner pieces 3b facing the left and right leg outer pieces 3a. Are integrally formed in a rectangular parallelepiped. Thereby, an opening part is formed in the mounting part frame 2, and the left and right leg parts of the electronic device packaging body 1 as shown in FIG. 2 are formed in a rectangular parallelepiped.

FIG. 2 shows a state where the electronic device packaging body 1 shown in FIG. 1 is assembled.
Similarly to the left and right legs 3, the upright portion 4 includes an upright portion outer piece 4 a and an upright portion inner piece 4 b, and an upright portion engaging piece at an end portion of the upright portion inner piece 4 b facing the upright portion outer piece 4 a. 4c is formed with a triangular prism integrally with the upright portion inner piece 4b by inserting a piece into the engaging groove of the upright portion slit 2a. Thereby, the opening part 7 is formed in the mounting part frame 2, and when the cushioning material 1 is stored in the packaging box, the upright part 4 can support the top surface of the packaging box from below to reinforce the strength. it can.

FIG. 2 shows a state where the electronic device packaging body 1 shown in FIG. 1 is assembled.
The front / rear leg portion 6 includes a front / rear leg outer piece 6 a, a front / rear leg inner lower piece 6 b, a front / rear leg inner piece 6 c, and a front / rear leg engagement piece 6 d. It is formed. The front and rear legs 6 bend the front and rear legs outer pieces 6a downward with respect to the placement frame 2, and further bend the front and rear legs lower pieces 6b below the front and rear legs outer pieces 6a. Further, the front / rear leg inner piece 6c is bent upward from the inside of the placement section frame 2, and the front / rear leg engaging piece 6d is fitted into the front / rear leg slit 2a. Thereby, the opening part 7 is formed in the mounting part frame 2, and the front-and-rear leg part of the packaging body 1 for electronic devices as shown in FIG. 2 is formed in a rectangular parallelepiped. In this way, the stacking unit frame 2 is constituted by the left and right leg parts 3, the standing part 4, and the front and rear leg parts 6, and forms an electronic device packaging body 1 as shown in FIG.

FIG. 3 shows a state in which the left and right legs of the electronic device packaging body 1 shown in FIG. 2 are assembled.
At the end of the left and right leg inner piece 3b facing the left and right leg outer pieces 3a, the left and right leg engaging pieces 3c are fitted into the engagement grooves with the left and right leg slits 2a on the left and right leg inner pieces 3d. A piece is inserted, and the tip of the left and right leg engaging pieces 3c is enlarged so that the engagement is not released.

  FIG. 4 shows a state in which the films 5a and 5b are attached to the electronic device packaging body 1, and FIG. 5 shows a state in which the electronic device packaging body 1 to which the film 5 is attached is assembled. The film 5a is adhered and fixed to the two left and right leg lower pieces 3b. The film 5 has a certain degree of bending on the mounting portion frame 2. In addition, the film 5b (not shown) in FIG. 4 is attached to all the portions in contact with the placement unit frame 2 in a mode of closing the opening 7 from the surface of the placement unit frame 2.

  FIG. 6 shows a mode immediately before the accommodation product 10 such as an electronic device is accommodated in the electronic device packaging body 1. As shown in FIG. 6, a sufficient space can be formed between the film 5 a and the film 5 b by lifting the leg portion 3 above the placement portion frame body 2. That is, even when the gap between the film 5a and the film 5b is insufficient in the state where the package 10 for the electronic device is accommodated, the gap between the film 5a and the film 5b is large as shown in FIG. Therefore, the accommodating operation can be performed smoothly.

  FIG. 7 shows a state in which the electronic device packaging body 1 containing the storage product 10 shown in FIG. 6 is assembled as shown in FIGS. 2 and 5. Compared to the package 1 for electronic equipment in a state in which the stored product 10 is not stored, the film 5a is tensioned depending on the thickness and height of the stored product 10, and the stored product 10 can be firmly held and fixed. FIG. 8 shows a cross section taken along the plane AA of FIG. In this way, the left and right leg portions 3 are bent below the placement portion frame body 2 so that the film 5a is pulled downward and tension is applied, and a force is applied in the direction of pressing the stored item 10 against the film 5b. Even when the electronic device packaging body 1 in this state is stored in a packaging box (not shown), the stored product 10 is not detached from the electronic device packaging body 1, and there is no possibility that the stored product 10 is damaged during transportation.

  FIG. 9 is a perspective view showing a film pressing experiment of the electronic device packaging body 1, and FIG. 10 is a cross-sectional view taken along the line BB in FIG. 9. In the experiment, in a state where the stored item is stored between the films, the extra length portion 4 of the film 5a is pressed by the tension gauge 50, and the elasticity, that is, the tension generated in the film 5 is confirmed. In the pressing experiment, a numerical value (unit: N) when pressing at a right angle to the extra length portion of the film up to a depth of 1 cm using a tension gauge in which the pressing surface at the front end in contact with the film is a square of 1 cm in length and width. This is done by checking the elasticity.

  In the experiment, the outer dimensions of the electronic device packaging body 1 were 340 mm long × 240 mm wide × thickness (height of the leg) 40 mm. Further, an aluminum plate formed with a plurality of types of dimensions is prepared as the stored item 10. The outer dimensions of the stored items are 240 mm long × 170 mm wide, and a total of five types having a thickness of 1 cm, 2 cm, 3 cm, 4 cm, and 5 cm were used. The film 5 employs a polyurethane film as a test film material, has a thickness of 70 μm, and has a length of 440 mm (with an extra length of 50 mm for the vertical dimension of the electronic device packaging body 1) × width of 310 mm (The extra length is 35 mm for the lateral dimension of the electronic device packaging body 1). In addition, in the state in which each stored item is stored in the electronic device package 1 using a bar-type tension gauge 50 (measurable up to 30N = 3,060 g) as a measuring instrument, the longitudinal direction of the test film material is measured. This was done by changing the length. In addition, the numerical value in the bracket | parenthesis of the thickness of the stored item of Table 1 shows the maximum value (unit: cm) of the depth of the sinking of the film 5b.

The depth of sinking of the film 5b in the experiment occurs when the stored item 10 of the electronic device package 1 is placed on the film 5b. The weight of the stored item 10 is 1 kg at a thickness of 1 kg, 2 kg at a thickness of 2 cm, 3 kg at a thickness of 3 cm, 4 kg at a thickness of 4 cm, and 5 kg at a thickness of 5 cm. The depth becomes deeper. In this experiment, this affected range is clarified and the elasticity of the film 5a is confirmed.

According to the above experimental results, it is considered that the tension applied to the film 5a of the electronic device packaging body 1 is most preferably in a state where the thickness of the stored item 10 is 3 cm to 4 cm. That is, it is understood that the tension of the film 5a is desirably 4.3 N / cm ² to 5.8 N / cm ² , and most desirably is approximately 5.1 N / cm ² to 5.5 N / cm ² . In addition, when the state in which tension was applied to the film 5a within the range of the numerical value on the storage product 10 having various thicknesses and sizes, the fixed state of the film 5b of the placement unit frame 2 and the storage product 10 is as follows. The result was almost the same. If the tension applied to the film 5 is a high value exceeding this range, the tension is too strong, and the film 5a is enlarged. Conversely, if the tension applied to the film 5a falls below this range, the tension is weak and the film 5a is made smaller.

Since the placement unit frame 2 is a cardboard, when a certain amount of force is applied to the placement unit frame 2, the placement unit frame 2 is distorted and the opening of the placement unit frame 2. 7 is unable to maintain the tension of the film 5b stretched to 7, and a large gap is formed between the film 5a, and the stored product 10 can be held when the tension of the film 5a is 7.4 N / cm ² or more. I found out that it might disappear. Further, both the film 5a and the film 5b have a certain degree of elasticity, but there is a limit to this. For this reason, when storing the different thickness storage goods 10 using the same mounting part frame 2, it is necessary to make the length of the film 5a suitable for the size of the individual storage goods 10 (clearance or margin). There is. The above-described experiment is an examination of the tension of the film 5a when the thickness of the stored item 10 is changed, and the optimum tension is examined. Therefore, for example, if the stored product 10 becomes larger than the experimental result described later, it is necessary to select a size of the film 5a that provides an appropriate tension so that the stored product 10 does not detach from the placement unit frame 2.

  According to the electronic device packaging body 1 as described above, since all the members except the film 5a and the film 5b can be formed of one cardboard material, the cost required for the formation can be suppressed. Since it consists of these members, management is not complicated and the convenience is very high. Moreover, a certain degree of freedom can be secured in the height direction by cutting out the film 5a larger than the mounting part frame 2, bending it, and attaching it, without changing the size and shape of the packaging 1 for electronic equipment. Both can accommodate various sizes of stored items. Further, by forming the opening 7 in the mounting portion frame 2 and attaching the film 5b from the surface, the stored product is sandwiched and fixed between the film 5a and the film 5b. Even if a large impact is applied to 1 itself, the impact transmitted from the unillustrated packing box to the mounting frame 2 can be absorbed by the film 5a and the film 5b, and the stored items can be protected more reliably. . Moreover, since the packaging body 1 for electronic devices can be easily expanded and assembled, it can be used repeatedly, and when it is not used, it can be stored to ensure storage.

  As mentioned above, although the Example of this invention was explained in full detail, this invention is not limited to the said Example, A various deformation | transformation implementation is possible within the range of the summary of this invention. For example, the engaging pieces 3c, 4c, and 6d of the left and right leg parts 3, the front and rear leg parts 6, and the upright part 4 have been illustrated and described. There is no problem.
