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 support 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.

() Structure of the invention Specific means for solving the problem A column consisting of rectangular cylindrical column structural members that can be folded flat and removably joined at the top and bottom via multi-stage connecting parts, with at least one corner The part includes an adhesive plate 3, which is attached on the inside to the two side plates forming the corner part.
3, and a locking piece 2 having a triangular shape having a fold line L in the center spanning the adhesive plates 3, 3, or having a protrusion 4 connected to one side partitioned by the fold line L. The corner of the locking piece 2 at the upper end of the other column component, which is different from the corner provided on the column component, has a vertical fold line M in the center. There are locking protrusions 11, 11 on both upper ends.
and a rectangular cylindrical support component to which a locking plate 10 is fixed, and the locking projection 11 is connected to the locking piece 2.
The present invention provides a support for a multi-stage connected display board with an engagement mechanism that engages with the inner surface of the side edge of the display board, and when folded, protrudes outward and is disengaged from the locking piece 2 that is folded in half.

Effect: When the support component having a locking piece on one end edge and the support support component having a locking plate at the end corresponding to the locking piece are both folded flat, the locking piece is attached to the other support. Similarly, the locking plate is inserted into the other strut component through the two folded locking pieces, and after the ends of both strut components are brought into contact with each other, each strut is inserted. When the constituent members are assembled to form a rectangular tube shape, the locking piece that was folded in two into a flat shape and protruding outward rises into a flat plate shape, so that the upper end of the protruding portion of the locking plate is aligned with the locking plate. It engages with the upper surface of the inner edge of the piece, and each strut component member will not come out.

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 post that is made up of rectangular cylindrical support members that are removably joined at the top and bottom via multi-stage connecting parts, and the support can be used to attach a display board or to directly display a display. and use it.

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.

Right-angled isosceles triangular locking pieces 2, 2 are attached to two opposing corners of the lower end of the strut component 1, with fold lines 1, 1 provided on both sides of the locking pieces 2, 2, respectively. It is fixed via plates 3 and 3 to the inner surface of the two side plates that form the respective corners. the locking piece 2,
2 further has a fold line L in the center, and a protrusion 4 on either side defined by the fold line L on the oblique side.
are installed in succession.

In addition, a vertical fold line M is placed at the center of each of the two corner parts of the supporting post forming member 1 at the upper end of the opposing supporting post forming member 1', which are not opposite to the two corners where the locking pieces 2, 2 are provided.
A locking plate 10, 10, 10, 10 having locking protrusions 11, 11 on both sides and an upper edge, the upper part of the locking plate 10, 10, 10, 10 protrudes from the end, and , is fixed to the inner surface of the second side plate forming the corner so that the fold line M matches the ridgeline of the corner. At this time, each locking protrusion 11 is not fixed to the side plate.

In order to connect the above-described respective strut constituent members 1, 1', first the strut constituent members 1 are folded along the ridge line of the corner where the locking piece is provided, and then the strut constituent members 1'
Fold each piece flat, using the ridgeline of the corner where the locking plate is not provided as the crease. At this time, the locking pieces 2, 2 of the strut component 1 are connected to the fold lines l, l, and L.
It is folded in half and protrudes downward. The upper edge of the locking plate 10 of the strut component 1' is
The locking piece 2 is inserted through each of the folded locking pieces 2, 2 and protrudes at the same time,
2 into the strut component 1, and bring the ends of both strut components 1 and 1' into contact with each other.

Then, in this state, each pillar component member 1,
1' is assembled into the original square cylindrical shape, both strut constituent members 1 and 1' are stacked end to end,
At the same time, the locking pieces 2, 2 rise up into a flat plate shape, and the upper surfaces of both side edges, more specifically, the vicinity of the fold lines 1, 1,
each member 1 and 1' are completely joined.

After that, in order to maintain this square cylindrical state, a cross-shaped reinforcing plate can be inserted, or a reinforcing plate 20 that can be folded into a flat square shape with cuts on one diagonal and fold lines on the other diagonal. This can also be done by attaching it inside and engaging and disengaging protrusions provided near the intersection of each diagonal at the upper end of each diagonal.

In this embodiment, the protrusion 4 is provided on the locking piece 2 in order to facilitate the insertion of the locking plate 10 into the locking piece, and also to ensure that the locking plate 10 is securely attached to the locking piece when joined. 2
This is provided to engage the upper surface of one side edge of the holder and to prevent it from slipping off during use. Although it would have a great effect if provided, it is not necessary.

Regarding the height at which the locking plate 10 projects, in this embodiment, the locking piece 2 is projected slightly downward from the lower end of the column component 1, Since it also functions as an insertion piece that fits into the inner surface of the corner, the lower end of the locking protrusion 11 of the locking plate 10 is necessarily inward from the upper end of the strut component 1' by the protrusion of the locking piece 2. I'm setting it to go in the direction. In other words, the height of the locking piece and the locking plate is determined by the combination of the locking piece and the locking plate so that they can be engaged.

Next, to describe the constraints on the horizontal length of the locking plate 10, as can be seen from the above-mentioned joining means, it is clear that it needs to be long enough to engage with the locking piece when joined, but it is also necessary to have a length that is long enough to engage the locking piece when it is joined. When it is,
The length must be set so that it can be inserted and removed freely into the space formed by the inner ends of both locking pieces.

The present invention is not limited to the above-mentioned embodiments; for example, the shape of the locking piece does not have to be a right isosceles triangle, but can be any shape as long as it can straddle the two side plates forming the corner in a flat plate shape. It doesn't matter if it is. However, one additional condition is that it can be folded in two.

Similarly, it is also possible to provide the locking plates independently, one by one, instead of having two locking plates connected to each other via a fold line as in the embodiment of the present invention.

In addition, it is sufficient to provide at least one locking piece and one locking plate each, and the locking piece at the end forming the connecting part of each pillar component, or the part where the locking plate is not provided. By providing an insert piece etc. in the holder, it is possible to join in a stable state and to ensure complete engagement.

Similarly, when increasing the number of strut components by 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. Moreover, since the engagement mechanism itself is not visible from the outside, the appearance is extremely good.
