Description

[Detailed explanation of the invention] () Purpose of the invention Industrial application field This invention is a rectangular cylindrical support that can be used in a wide range of situations, from large ones such as life-sized displays to small ones such as counter displays. This relates to a display support that consists of multiple layers of structural members connected at the top and bottom.

Furthermore, the column of this invention not only can be folded into a flat shape, but also has an engagement mechanism for assembly and connection, so it will not come off accidentally during use.

Conventional Technology Reflecting the recent trends in resource and energy conservation, low-cost and highly effective advertising and promotional activities are becoming mainstream. Under such circumstances, in the field of displays that this invention aims at, displays that use inexpensive paper and cardboard as materials and are equipped with a folding function to further reduce transportation and storage costs are becoming mainstream.

This tendency is especially noticeable in large-sized displays, and the display that the present invention aims at, which consists of a display board and a support, is no exception to this. To give a concrete example, Jikoko 50-
21429, Jitko Sho 58-12192, etc. As exemplified by these two cases, most of the products on the market are display boards that are divided into multiple pieces.
It is structured so that it is pasted on each section divided by the fold lines of the integrated support and folded through the fold lines of the support. There are also many products with this configuration that have the ability to be assembled with one touch, as shown in the two examples above.

Problems that the invention aims to solve However, although the above-mentioned conventional products are extremely easy to use in stores, they are extremely complicated and difficult to design and manufacture, resulting in high costs. It becomes expensive. In addition, the fold line part on the support often broke during repeated assembly and folding, making it unsuitable for long-term use.

Therefore, this invention focused on the pillars of the display,
The cylindrical support can be easily designed and manufactured by dividing it into multiple parts to reduce the overall cost and can be stored in an extremely compact state.Assembling can be done by simply connecting each support component at the top and bottom.
The connection can also be done automatically.

They abut and stack, and at the same time the locking plate rises into a flat plate shape, and the locking protrusion of the locking hole enters and engages with the locking hole of the locking plate, so that it may come off accidentally during use. It is not.

Example In order to make the present invention more clear, we will explain it in detail according to the example shown in the drawings below.

The present invention is a display column consisting of rectangular cylindrical column components removably joined at the top and bottom via multi-stage connecting parts, and can be used by attaching a display plate or directly displaying information. Masu. The support component used in this invention must be able to be folded flat, so there is no problem with square or regular hexagonal cylinders, but with pentagonal cylinders, each side plate It must be able to be folded flat considering its horizontal length.

In the example shown below, the support component is square cylindrical. In addition, the number of connections was set to two, which is the minimum required to explain the configuration of the connecting part.

The column component 1, which is made up of four side plates 2, 2, 2, 2, has a pair of opposing ridge lines inside its lower end.
On the inner surfaces of the side plates ₂ , 2, _2, 2 forming r 1 and r 1 ′, respectively, there is a rectangular shape that straddles the ridge lines r ₁ and r ₁ ′ and whose lower end protrudes from the lower end of the column component 1. The locking plates 3, 3' are fixed via adhesive plates 4, 4, 4', 4' which are connected to both sides of the locking plate 3 via fold lines. Further, the locking plates 3, 3' have vertical fold lines L, L' in the center, and locking holes 5, 5' superimposed on the vertical fold lines.

Next, the column component 1' located below the column component 1 similarly has four side plates 2', 2',
2', 2' are arranged in series, and the ridge line r ₁ ,
The inner surfaces of the first side plates ₂ ' and 2' adjacent to the ridge lines r ₂ and r ₂ ', which are vertically connected to r 1 ', have a horizontal length equal to the length between the ridge lines r ₂ and r ₂ ', and the support component The reinforcing plates 6, 6' reaching to the lower ends of the reinforcing plates 6, 6', respectively, are attached to one side of the reinforcing plates 6, 6' through adhesion plates 7, 7', which are connected to each other via a fold line. The reinforcing plates 6, 6' are fixed at positions where they overlap inside the ridge lines r _{2 and r 2 ', and the reinforcing plates 6 and 6' are made to protrude within the plane formed by the ridge lines r 2 and r 2} '. The upper ends of the reinforcing plates 6, 6' are set lower than the upper end of the column component 1' by the protrusion of the locking plates 3, 3'.

Furthermore, a locking piece 8 is attached to the upper part of the reinforcing plate 6, 6'.
The locking pieces 8, 8' have locking protrusions 9, 9' on the upper portions of the sides facing the open side of the reinforcing plates 6, 6', respectively.

To connect the above-mentioned strut components 1 and 1', first fold both members flat using the ridge lines r ₁ , r ₁ ′, r ₂ , and r ₂ ′ as creases. Then, the locking pieces 8, 8 of the other column component 1' are inserted into the locking plates 3, 3' which are bent flat in the direction of the ridge lines _r1 , _r1 ' through the fold lines L, L'. ', and at the same time hold the member of the locking plates 3, 3 protruding from the lower end of the column component member at the inner edge of the upper end, and bring the ends of the column component members 1, 1' into contact with each other.

Next, while in this state, both support pillar components 1, 1'
If the ridge lines r ₁ , r ₁ ′, r ₂ , and r ₂ ′ are pushed inward and assembled into the original rectangular tube shape, the ends of both members will be stacked on top of each other, and at the same time the internal locking plates 3 and 3 ′ will be stacked on top of each other. rises into a flat plate shape, and the reinforcing plates 6, 6' are pushed by the ridgeline and move to come into contact with the ridgeline facing the open side, and in response to this movement, the upper locking pieces 8, 8'
The locking protrusions 9, 9' are connected to the locking plates 3, 9' respectively.
Enter the locking holes 5 and 5' at 3' from the inside and engage.

In addition, in this embodiment, in order to maintain the rectangular cylindrical state of the pillar constituent members 1, 1', the reinforcing plates 6,
Notches 10, 10' are provided in the center of the plate 6', and the notches provided at the top of the separately provided reinforcing plate are inserted into the notches 10, 10', and the plate functions as a cross-shaped reinforcing plate as it is. Masu.

The present invention is not limited to the above-mentioned embodiments; instead of attaching the reinforcing plate by pasting it, it can be made to protrude from the ridgeline in a blank state, and then folded back inward using the ridgeline as a crease and provided integrally with the side plate. Also, the dimensions can be made very low, and even if the horizontal length is set shorter than the length between the two opposing ridgelines, it will no longer function as a reinforcing plate, but it can be used separately. Providing a cross-shaped reinforcing member will not cause any problems.

Also, when inserting the locking piece into the locking plate as in the above embodiment, the two locking pieces are inserted when the strut component is folded flat so that the relative horizontal length of the two locking pieces is the smallest. If the pieces are set so that they overlap completely, this invention will be more convenient to use.

Similarly, when increasing the number of strut components to three or four, a connecting section consisting of a locking piece and a locking plate is provided at the appropriate end of each strut component.

() Effects of the invention As is clear from the above description, the invention has the following effects:
Because the book support is formed from multiple support structure members that can be folded flat,
It can be transported and stored in a very compact state. In addition, when in use, all you have to do is insert the locking pieces and locking plates of each flat member and then assemble them into the original square tube shape, and they will automatically engage and will not come off accidentally. Furthermore, since the engagement mechanism cannot be seen from outside, the appearance is extremely good.
