Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a support for placing articles, and more particularly to a cylindrical support that is hollow in the height direction.

[Conventional technology]

Traditionally, cylinders made of cardboard have been used as supports on which products are placed, such as in displays. However, when a square cylinder is used, multiple vertical edges are created, making it difficult to feel the impact from the cylinder. It has the disadvantage of being hard and difficult to satisfy in terms of appearance. Also,
Since a highly rigid material such as cardboard is used directly, there are also drawbacks such as poor print quality on the surface.

[The problem that the idea attempts to solve]

This project solves the above problem by making it possible to curve the vertical corners of the cylindrical support, giving it a softer feel and improving its appearance, as well as printing on the surface. It makes it possible to make it easy and beautiful, as well as
This increases the strength of the support base in the axial direction.

[Means for solving problems]

In order to achieve the above-mentioned purpose, the cylindrical support of the present invention consists of a cylindrical sheet made of a somewhat stiff paper or other material, and a core plate made of cardboard or other material with high rigidity that covers almost the entire circumferential length of the cylindrical sheet. is arranged, and the core plate has a substantially V-shaped bent part that is bent inward of the sheet and provided over the entire length of the core plate at intervals in the circumferential direction of the sheet. The core plate is attached to the sheet only at the straight portions between the bent portions, and the bent portions and the sheet are spaced apart from each other.

[Effects of action and design]

This cylindrical support base has a cylindrical sheet placed outside the core plate as described above, and the core plate extends over the entire length of the core plate and is bent inward of the sheet. It has a roughly V-shaped bent part, and the bent part becomes a corner part of the core plate, and the bent part and the sheet are spaced apart from each other, so the part of the sheet facing the bent part has an arc shape. Therefore, each corner of the rectangular tube can be rounded, and a good-looking support stand can be obtained. Since the core plate has a sheet on its surface, it is easy to print on it, and it is possible to improve the finish. The core plate has a bent part that protrudes inward from the support base over its entire length, so when placing an article on the support base, the top plate can be placed on the core plate. Since the top plate is easy to place and each bent portion is columnar, the support base has high strength in the axial direction and can sufficiently withstand large loads.

〔Example〕

To explain the embodiment of the cylindrical support of the present invention in the drawings, 1 is a cylindrical sheet, which is made of slightly thick paper, synthetic resin sheet, nonwoven fabric, woven fabric, etc. Any sheet made of any material can be used. A core board 2 is made of a rigid material such as cardboard, a synthetic resin board such as polypropylene, or a wooden board such as plywood. There is. Reference numeral 3 denotes bent portions formed on the core plate 2 at four locations at intervals in the circumferential direction. It is provided over the entire length in the axial direction. Reference numeral 4 denotes a straight portion of the core plate 2 between the bent portions 3, 3. The core plate 2 is adhered to the inner surface of the sheet 1 only at each straight portion 4, and the bent portion 3 is separated from the sheet 1. That is, the shape of the cylindrical sheet 1 is maintained by the core plate 2 affixed to its inner surface, and when there are four bends 3, the sheet 1 becomes rectangular; If so, it will be a triangle. The bent portions 3 can also be formed at four or more locations. In this embodiment, the cross-sectional shape of the bent portion 3 is V-shaped, but it may be arbitrarily shaped such as an arc. Reference numeral 5 denotes a support piece that projects in the extending direction of the straight portion 4 from a portion of both end edges of the bent portion 3 in the circumferential direction of the core plate 2. It is formed integrally with the straight portion 4 by cutting the straight portion 4 into one piece. This bearing piece 5 is attached to the core plate 2 for the bending part 3.
The shape of the sheet 1 is adjusted by supporting the portion of the sheet 1 that is spaced apart from the inner surface of the sheet 1, and it is suitable to provide a plurality of portions on each edge of the folded portion 3, but it is optional, such as providing one portion. It is.

The core plate 2 is divided into two parts in the circumferential direction, and is attached to the sheet 1 by joining the protruding edges 6 provided on the opposing edges thereof to each other so as to protrude inward from the sheet 1. There is. Although this configuration is suitable for folding the support base, it is also possible to do so without providing the protruding edges 6, by abutting the opposite edges of the core plate 2, or by bonding them in an overlapping manner. The edge of the sheet 1 in the axial direction may be made to protrude from the core plate 2 as in the embodiment.
It is suitable for placing a top plate on top or attaching a bottom plate, but when the top plate is larger than the diameter of the support stand or when the bottom plate is not used, the height of sheet 1 and core plate 2 should be the same. do.

As described above, in this cylindrical support, the core plate 2 is attached to the inside of the cylindrical sheet 1, and the core plate 2 is placed at a position corresponding to each corner of the sheet 1. The core plate 2 has a bent portion 3 having a V-shaped cross section, which extends over the entire length of the core plate 2 in the height direction and is bent inwardly from the sheet 1. Therefore, if the length in the circumferential direction of the sheet 1 facing the folded part 3 is made longer than the distance between the opposing edges of the folded part 3, that part will become circular as shown in FIG. It has an arc shape, and each corner of the support base can be rounded, providing a good-looking support base. for example,
The core plate 2 with the folds of each bent part 3 and the like is applied to only the straight part 4 and adhered to the straight sheet 1, and both ends of the sheet 1 are adhered to each other to form a cylinder. By making the core plate 2 into a shape and bending each bent portion 3 of the core plate 2 inward, a rectangular tube with rounded corners can be easily obtained.

If supporting pieces 5 protruding in the extending direction of the straight portion 4 are provided at the opposing edges of each folded portion 3, they will support both ends of the portion of the sheet 1 facing the folded portion 3. Each corner of the tube can be rounded to a more natural shape. However, even without the support piece 5, the rigidity of the sheet 1 itself creates a rounded shape.
The bearing piece 5 can also be omitted.

When this support stand is used, for example, as a stand for placing articles, a top plate is placed on the core plate 2. Since each bent portion 3 protrudes inward from the core plate 2, the top plate is placed on the core plate 2. can be placed stably, and since the bent portion 3 serves as a pillar, it is possible to withstand a large load and it is also possible to place heavy objects. If the core plate 2 is provided with a protruding edge 6, this will also support the top plate and will contribute to increasing the strength of the support base, but the protruding edge 6 may be provided arbitrarily.

Since this support base has a core plate 2 arranged inside the sheet 1, if the sheet 1 is made to protrude from both ends or one end of the core plate 2 as in the embodiment, the top plate and bottom plate can be placed inside the sheet 1. By fitting them, they can be easily attached to the support base, and they can also be prevented from moving in the radial direction of the support base, making it possible to attach the top plate and bottom plate in an attractive and stable manner. Furthermore, if the entire or a part of the top plate or the like is dropped into the seat 1, the shape of the support base can be maintained constant by the top plate or the like.

If the cross section of the support base is square, if the core plate 2 is divided into two pieces and the cross section of the bent part 3 is made V-shaped, the sheet 1 can be held at the joint between the core plates 2 and 2. By folding it inward and folding each bent portion 3, it can be folded as shown in FIG. 3 to reduce its bulk, making it easier to transport.

By using a material suitable for printing as the sheet 1, printing can be applied easily and beautifully regardless of the material of the core plate 2, and a good-looking support can be obtained.
