Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display board, and more particularly to a display board such as a guide sign or a danger sign used in traffic control and a traffic accident, and various other displays for commercial purposes. It relates to improvement of a display panel.

[0002]

2. Description of the Related Art In the case of traffic control, a traffic accident, or the like, it is sometimes necessary to urgently install a stop sign, an arrow regulating plate indicating a traveling direction, etc. on a road for the purpose of traffic control.

[0003] The road signs and the like used for these are portable because of the urgent purpose of use, and are generally always loaded on a patrol car or the like so that they can respond immediately to an emergency.

[0004]

Conventionally, as these portable signs, there are, for example, a plastic triangular cone (cone) and an assembled arrow display board, and the plastic triangular cone is lightweight. However, due to the large volume, there is a limit to the number of vehicles that can be loaded on a patrol car or the like. There was a drawback that it was easily overturned or blown off, resulting in poor stability.

[0005] In the case of the arrow control plate, the folded main body has a flat shape, so that even a vehicle with a small loading capacity such as a patrol car can be loaded in a large amount, and the responsiveness is considerably improved as compared with a plastic triangular conical cylinder. There is a drawback that the leg structure for standing and supporting is complicated, the operation at the time of installation is troublesome, the wind resistance is poor, and if a back wind enters, it can easily fall down and become useless as a sign.

However, there is a type in which three plates are connected so as to be foldable and assembled into a triangular cylindrical shape when used, and are placed horizontally with one surface as a base. However, in this case, the installation base is flat. When installed on uneven roads or on a scattered road surface such as gravel, there is a drawback that the function as a sign is impaired because even a weak wind rotates around the convex support point.

[0007] Furthermore, the assembling type display panel has a disadvantage that useless time may be spent until installation if the structure and the assembling procedure are not well understood. In addition to the above-mentioned emergency use, the display may be frequently changed for commercial purposes, for example, advertising, product price display, and the information may be changed and displayed intermittently at regular time intervals. In each case, the work of installing and removing the display board was sometimes troublesome.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and is lightweight and easy to carry. Also, it is thinly folded during transportation, does not take up space for storage management, and is very easy to use. An object of the present invention is to provide a display panel that can be assembled, has excellent visibility and weather resistance, and has good wind resistance.

[0009]

That is, in the display panel according to the first aspect of the present invention, two front panels having legs formed on the lower side are connected at the upper side so as to be foldable. The bottom sides excluding the legs are connected by a bottom plate that is bendable at a central folding line parallel to the bottom side, and the bottom plate is added with a weight that shifts the entire center of gravity downward. It is a feature.

[0010] By connecting the two front plates for displaying freely at the upper side and connecting the lower sides with the bendable bottom plate, it is possible to stand upright on the base surface in a triangular shape in side view. By adding weight to the bottom plate, the display plate can be made to stand alone just by throwing it out, and when folded, it can be folded naturally only by lifting it up by the weight of the bottom plate.

According to a second aspect of the present invention, there is provided a display panel having a triangular shape in a side view formed by joining two sides of the two front panels with opposing sides thereof and forming the two front panels and a base surface. An elongated triangular side plate forming a side surface is connected to bend freely, and opposing sides of the elongated triangular side plate are connected by a bendable connecting member.

That is, in the display panel of the first aspect, a necessary display can be performed even on a triangular portion in a side view. The display panel of claim 3 has a trapezoidal shape in which the width is narrower as the two front plates of claim 1 or 2 move toward the upper side,
In addition, a reinforcing edge member extending from the upper side to the leg along the side of the front plate is provided integrally.

With this configuration, the standing display panel is more stable in shape, and can withstand long-term use even under severe use conditions such as throwing it off with a reinforcing edge. Furthermore, when combined with the configuration of claim 2, the side plate is inclined toward the rear side of the front plate when standing upright in relation to the position of the center of gravity of the long triangular side plate. Folding on the back is self-contained, facilitating folding.

According to a fourth aspect of the present invention, there is provided the display panel according to the first, second, or third aspect, wherein the two front plates are reversible with the bottom plate interposed therebetween. It is characterized in that a connecting member that can be attached and detached in any of the front and back positions of the front plate is provided.

That is, the display panel is so-called reversible, and if different displays are provided on the front and back sides of the front panel, the display can be easily changed by flipping the front panel over the bottom panel. .

According to a fifth aspect of the present invention, in the display panel of the first, second, third, or fourth aspect, the front plate, the bottom plate, and the side plates are each formed of a plastic panel made of a material that does not generate harmful incineration gas. It is characterized by being done.

Display panels are required to have rain resistance, light weight, etc.
Plastic is generally used as a material satisfying this. However, some of these materials emit harmful gases when incinerated, which can impose severe restrictions on disposal methods.

In order to solve these problems, a material which does not emit harmful gas is used, and when it becomes unnecessary, it can be incinerated. The display panel according to claim 6 is the display panel according to claim 1, 2, 3 or 4, wherein the front plate and the side plate are provided with a light-reflecting base surface having a reflectance of 100% or more, respectively. It is characterized in that a necessary display is displayed by covering the light reflecting surface on the lower ground.

When a character or graphic is displayed on a reflecting surface having a high light reflectance, the light beam of the reflected light may be extremely invisible.
Such a problem can be solved by reversing the relationship between the base surface and the light reflecting surface of the display surface.

When the light reflectance is 130% or more, the visibility becomes more remarkable.

[0021]

Next, an embodiment of the present invention will be described. FIG. 1 is a perspective view of an embodiment of an assembled state of the display panel of claim 1, and FIG. 2 is a front view of the folded state.

The display panel 1 according to the first aspect of the present invention has a leg 2 on the lower side 2A.
3, two front plates 2 formed by extension are connected to each other by a hook-and-loop fastener or hooks at an upper side 2C so as to be foldable as shown by a dotted line in FIG.
A, 2A are connected to each other by a bottom plate 3 which can be freely bent at a center fold line 3A parallel to the lower side.
As shown by a dotted line in the figure, a weight 4 for shifting the entire center of gravity G below the geometrical center of gravity g that is obtained graphically is added.

As shown in the figure, the weight 4 may be such that the weight 5 is mounted and fixed on the bottom plate 3, or the bottom plate 3 itself may be formed of a heavy material. The weight 5 can be made of metal, concrete, etc., as long as it adds a necessary weight, and the material is not limited. However, a material made of a compressed synthetic material using waste paper waste or the like can be used. Therefore, its use is preferred.

When the bottom plate 3 itself is made of a heavy material,
The bottom plate 3 can be formed of a compression synthetic material using waste paper waste or the like as a raw material. It is preferable that the position of the center of gravity G is as low as possible. Therefore, the weight of the weight 4 is made as large as possible as long as the strength of the material forming the display panel allows.

Necessary signs, characters, figures, and the like are displayed on the front plates 2 and 2. 2D in the figure indicates a long hole for a handle provided on the front plate 2, and is provided as needed.

FIG. 3 and FIG. 4 are explanatory views of the use state of the display panel. First, when the display panel 1 is installed, as shown by a dotted line in FIG.
Lower vertically.

At this time, since the bottom plate 3 is added with weight, it is folded in two by its own weight and extends below the lower side 2A of the front plate 2. Since the front panel 2 of the folded display panel 1 is easily opened due to the thickness of the bottom panel 3, after the bottom panel 3 comes into contact with the base 6, the display panel 1 can be further lowered. 3 opens by its own weight, the front plates 2 and 2 also open their lower ends in conjunction with the bottom plate 3, and eventually stand up against the base surface 6 of the leg 2.

Therefore, the display panel 1 can be erected on the base surface 6 only by the lowering operation. Since the bottom plate 3 is given a weight that lowers the position of the center of gravity of the display plate 1, it can stand alone even if thrown away as shown in FIG.

That is, when the display panel 1 is thrown and thrown so that the bottom panel 3 comes first, the display panel 1 lands on the bottom panel 3 due to the relationship between the wind pressure and the position of the center of gravity, and after landing, the bottom panel 3 opens by its own weight. The front plates 2 and 2 also open in conjunction.

Since the position of the center of gravity of the display panel 1 is eccentrically located downward, the entire display panel 1 stably stands alone just like "rise and fall". By the way, when the display plate 1 is folded, the bottom plate 3 is folded by its own weight and extends downward. However, the width of the central folding line 3A of this extension portion is made smaller than the width of the front plate 2 as shown in FIG. In addition, it is desirable that the angle θ between the center fold line 3A and the line LL connecting the end of the center fold line 3A and the lower end of the leg 2B is 45 ° or more.

When the display panel 1 is thrown to be self-sustained, if the angle of incidence of collision with the base surface 6 is too close to horizontal, the base plate may slide down on the base surface and become unable to stand by itself. This is because

The angle of 45 ° or more is based on empirical values obtained by experiments of the present inventor. If the angle is smaller than 45 °, the angle of collision with the base surface is too small, and the angle of the folded state before being self-standing is reduced. This is because the display board sometimes falls down as it is.

FIG. 5 is a perspective view of the embodiment of the display panel 1 according to the second embodiment in an assembled state, and FIG. 6 is a side view of the folded state. A display panel 1 according to a second aspect is one in which a side plate is foldably attached to the display panel 1 shown in FIGS.

That is, as shown in FIG. 5, two front plates 2,
Each of the long sides 2E, 2E has opposing sides 7A, 7A attached to each other, and the long triangular side plates 7, 7 are flexibly connected to each other. ,
7A are connected by a bendable connecting member 8.

The connecting member 8 is formed of a flexible material such as cloth, and is detachably attached to the side plate 7 with a hook-and-loop fastener or the like. Is also good.

When the side plates 7, 7 are attached in this manner, the side surfaces can also be used as display surfaces. Further, since the side plate 7 only partially connects the opposing sides 7A, even if a cross wind is blown at the time of standing, the wind is well removed and the display plate can be prevented from falling down due to the wind pressure.

At the time of folding, the side plates 7, 7 are folded and stored on the back side of the front plate 2 as shown in FIG. In addition, the folded side plates 7, 7 open the front plates 2, 2 without permission, so that the expanding operation at the time of standing is also assisted.

When used in an upright position, the upright position is set up in the same manner as shown in FIGS. 3 and 4. However, the side plates 7 are formed so that the opposing sides 7A of the front plate 2 and the side plate 7 can be bent. Because they are connected, they do not hinder the expansion of the front plates 2 and 2,
Expands in conjunction with 2.

As shown in FIG. 2, the front plate 2 has a trapezoidal shape in which the width decreases toward the upper side 2C, and the front plate 2 extends from the upper side 2C along the side 2E of the front plate 2 as shown in FIG. It is desirable that the reinforcing edge member 2F reaching the portion 2B be provided integrally.

In the case of such a configuration, the lateral stability of the display panel 1 is improved, and the self-sustainability in the case where the display panel 1 is installed by being thrown out is further improved. When the side plate 7 is provided as shown in FIG. 5, the side plate 7 is inclined more inward than the relationship between the position of attachment to the inclined edge of the front plate 2 and the position of the center of gravity.

Therefore, when the display panel 1 is lifted and folded, the side panels 7, 7 are naturally folded to the back side of the front panel 2, and the removability is extremely improved. In addition, since the front plate 2 is reinforced by the reinforcing edge material 2F, it has excellent impact strength,
The durability against repeated use is also increased, and the durability is good even in a usage method in which the player can throw and throw himself.

Further, the leg 2 reinforced with the reinforcing edge 2F
It is desirable to apply anti-slip processing to the installation surface of B.
This is because it is possible to prevent a fall due to a slip when the player throws himself to throw himself or a movement due to a wind after standing.

FIG. 7 is an explanatory view of an embodiment according to claim 4.
FIG. 8 is an enlarged sectional view of the main part. Display plate 1 shown in FIG.
As shown in FIG. 1 and FIG. 2 or FIGS. 5 and 6, two front plates 2 and 2 of the display plate 1 are detachable at an upper side connecting portion 2G, and as shown by arrows with the bottom plate 3 interposed therebetween. The connecting member 9 on the upper side 2C is configured to be detachable in both the front and rear positions of the front plate 2 as shown in an enlarged view in FIG.

The connecting member 9 can be a hook-and-loop fastener as well as a hook as shown in the figure. Then, display is performed on both sides of the front plate 2, and the front plate 2 is inverted and used according to the purpose.

In this case, there are a maximum of four display types. When the side plate 7 is provided as shown in FIG. 5 and FIG. 6, the side plate 7 is also
The connecting member 8 on the opposite side 7A can also be attached to and detached from both the front and back surfaces of the side plate 7 using a hook-and-loop fastener or the like.

In this case, the number of types of display further increases, and a maximum of eight
Can be of any type. In the above embodiment, each of the front plate, the bottom plate, and the side plate is preferably formed of a panel made of a plastic that does not generate harmful incineration gas, for example, an environmental protection resin material such as polyethylene, polyester, or polypropylene.

This is because the display plate 1 can be incinerated when it is no longer needed, which is convenient for waste disposal or environmental conservation. As the plastic panel, a so-called plastic cardboard panel 10 in which the plastic sheet 10A is formed in a corrugated cardboard shape as shown in FIG. 9 is preferably used in terms of strength and weight reduction.

The front panel 2 and the side panel 7 of the display panel 1 of the present invention.
In the case where display is performed on a light reflecting surface for night visibility, if the light reflectance is 100% or more due to the anti-slope setting condition, the base surface 11A is used as a light reflecting surface. , The necessary display 11B on the light reflecting surface.

When a necessary character or graphic is displayed on the non-reflective surface on the light-reflective surface, the light-reflection surface can be easily recognized when the light reflectance is lower than 100%. In other words, the display is hidden in this beam of light, making it invisible.

Therefore, when the light reflectance exceeds 100%, the base surface 11A is a light reflection surface and the display is a non-anti-slope surface 11B. In this way, even if the ground surface 11A emits a light beam, the display of characters and the like appears black in the light beam, and the display becomes very clearly visible.

When the light reflectance is 130% or more, the visibility becomes more remarkable.

[0052]

As described above, the display panel according to any one of the first to sixth aspects can be installed independently by simply placing or throwing it at the time of installation due to the weight of the bottom plate, which is extremely simple. Can be installed in

In addition, anyone can install the apparatus without any special prerequisite knowledge, such as the structure and procedure, of the assembly. At the time of installation, the posture is stabilized by the weight of the bottom plate, and the points of contact with the installation surface are mainly the four points at the tip of the legs of the front plate. Can be installed stably regardless of

When the display panel is folded, the display panel is naturally folded by its own weight of the bottom panel 3 by simply lifting it upward. In addition, since it can be folded thinly during storage, the required number of sheets can always be loaded and stored in a narrow storage space, such as a patrol car.

In the display panel according to the fourth aspect, in addition to the above-mentioned effects, the front panel for performing display is so-called reversible, so that a single display panel can selectively use a plurality of displays according to the situation, and a maximum of eight screens can be used. Can be displayed, which has an effect that is versatile.

The display panel according to claim 5 uses plastic as a material for realizing water resistance, strength and light weight, but since these are made of incinerator, there is no need to worry about disposal. It has the effect of contributing to conservation.

Further, in the display panel according to the present invention, it is possible to solve the difficulty of seeing by the light beam of the reflection surface having a high light reflectance only by changing the combination of the display surface and the reflection surface of the base surface, and the implementation is very easy. This has the effect that the display is remarkably easy to see.
