There were problems as listed below.

■ If the inner shape of the resin molded product to be placed changes, it is necessary to completely rebuild it, and there is no compatibility with the inner shape of the resin molded product.

■ Since it is made of styrofoam (highly foamed material), it has poor scratch resistance, and the ends of the product are chipped due to galling during attachment and detachment, causing the shape of the styrofoam to change.

■ Since a mold is required, the manufacturing cost of the mold is high.

Furthermore, the resin molded article holder B had the following problems.

■ If the inner shape of the resin molded product to be placed changes, it must be completely replaced, and there is no compatibility with the inner shape of the resin molded product.

■ Since the metal round bars are bent one by one to match the plate gauge, the number of manufacturing steps is enormous and the manufacturing time is also long.

■ When a resin molded product is placed, it is supported by a hard wire, so a locally concentrated load is applied to the resin molded product, making it difficult to maintain the shape of the resin molded product.

(Means for Solving the Problems) Therefore, the present invention was made for the purpose of solving the above-mentioned problems, and to achieve this purpose, the present invention has a structure in which the upper part is a receiver for a resin molded product. A hollow body that forms a surface and has a gas sealed inside is provided, the hollow body is formed of a flexible material, and the means is fixed to a support member that supports the hollow body.

First, the structure of the first embodiment shown in FIGS. 1 to 3 will be explained.

Reference numeral 1 denotes a hollow body, the upper part of which serves as a receiving surface for the resin molded product 2 placed on it.This hollow body has air sealed inside 3, is made of a flexible material such as rubber, It has a cylindrical shape.

4 is a plywood board as a supporting member, and the hollow body l
It supports and fixes the hollow body 1, and is adhesively fixed to the lower surface of the hollow body 1.

The plywood board 4 has the shape of a rectangular flat plate, and its area is set to be large enough to support and fix the entire hollow body 1.

Reference numeral 5 denotes a belt as a shape-retaining member, which is used to partially pull the hollow body 1 to conform to the shape of the resin molded product 2 when the resin molded product 2 has a large recess. Both ends of the belt 5 are removably attached to both ends of the plywood board 4, respectively.

6 is a valve provided in the hollow body,
This valve 6 is for adjusting the air pressure inside the hollow body 1.

Note that a seam weld 7 (self-welded joint) is formed in the hollow body 1 during molding.

Next, the operation of the first embodiment will be explained.

First, air is injected into the interior 3 of the hollow body 1 through the valve 6,
When the hollow body l is swollen by air, both ends of the belt 5 are attached to both ends of the plywood board 4 so as to match the shape of the resin molded product 2 to be placed, and the hollow body l is partially pulled. The shape of the resin molded product 2 is set to be close to that of the resin molded product 2, and the resin molded product 2 is disposed on the subframe 8.

When the resin molded product 2 is placed on the hollow body 1, the shape followability of the hollow body 1 deforms the upper part of the hollow body 1 along the inner surface shape of the resin molded product 2, and the hollow body 1 is made of plywood. By being supported and fixed to 4, the resin molded product 2 can be supported in terms of a distributed load state, and the shape of the resin molded product 2 can also be maintained.

Next, a second embodiment shown in FIGS. 4 to 7 will be described.

In this embodiment, the shape-retaining member is eliminated, and the seam weld 7 cm (self-welded part) of the hollow body 1 is sandwiched between angle members 9.10 as supporting members, and tightened with ports 11 and nuts 12. This is an example in which the hollow body 1 is supported and fixed at two locations, one in the front and one in the rear.

Therefore, when the resin molded product 2 is not placed, as shown in FIG. 6 and FIG. By loosening and sliding the pallet 13 inward together with the wheels 16, 17, the hollow body 1 can be shortened in the folded state due to its deformability, and the length of the pallet 13 can also be shortened.

In this embodiment, a substantially quadrangular prism hollow body l and a substantially triangular prism hollow body 1' are bonded together, the lower surfaces of the rain hollow bodies l and 1' are adhesively fixed to a base 15 serving as a supporting member, and the base 18 This is an example in which a metallic round bar 19 is bent and welded. Therefore, in this third embodiment, by using a plurality of hollow bodies 1.1' and a round bar together, a complex shape can be formed. The receiver of the resin molded product 2 can be a stand.

Next, a fourth embodiment shown in FIGS. 10 and 11 will be described.

In this embodiment, the interior 3 of the hollow body 1 of a substantially square prism is divided into two groups 3a.
, 3b, and the hollow body 1 is adhesively fixed to a base 18 having an inverted cross-section as a support member.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments. Included in invention.

For example, the gas injected into the hollow body may be other than air, such as alcohol or nitrogen, and the supporting member may be a plywood board, an angle material, or an iron plate, an aluminum plate, or a plastic plate other than the base.

In addition, the shape-retaining member is not necessarily required, and if a shape-retaining member is used, a wire or the like may be used outside the belt, and the width of the shape-retaining member is The location, number, etc. of the installation may also be determined.

Further, the hollow body may also be divided into a plurality of chambers instead of one chamber, and each chamber may be provided with a valve.

(Effects of the Invention) As described above, according to the present invention, since the hollow body deforms to follow the shape of the resin molded product on which it is placed, the shape of the resin molded product when placed is not limited and the hollow body is This has the excellent effect of making it possible to share the body.

In addition, since hollow bodies can be shared, it is also possible to share pallets, which reduces the number of pallets that can be damaged. This has the effect of eliminating the need for storage space and reducing logistics costs.

Furthermore, since no mold is required, the cost can be reduced.

In addition, since the hollow body is made of a flexible material and gas is sealed inside, it is possible to prevent galling during attachment and detachment.Also, even when an external force is applied to the hollow body, the shape of the hollow body is maintained due to the restoring force of the hollow body. The effect is that it does not change.

In addition to the above-mentioned effects, in the first embodiment, since the valve and the belt are provided, when placing the resin molded product on the hollow body, the air pressure of the hollow body can be controlled by the valve, Further, by making the shape of the hollow body match the shape of the resin molded product using the belt, it is possible to obtain the effect that it can be made to fit the inner surface shape of the resin molded product.

In addition to the above-mentioned effects, in the second embodiment, since the length of the hollow body can be adjusted when no resin molded product is placed, the pallet can be made smaller when suspended from the pallet. This has the effect of eliminating the need to take up a large space for storing pallets.

In addition to the above-mentioned effects, in the third and fourth embodiments, since a plurality of hollow bodies or divided hollow bodies are used, resin molded products with large shapes or resin molded products with complicated shapes can be produced. This has the advantage that even products can be placed there.
