[0002]

2. Description of the Related Art Conventionally, as a sign device for roads, a sign device having a sign plate on which a required sign pattern is written on a surface of a plate material such as a metal plate or the like by a pole or the like is used. However, this configuration requires a foundation such as concrete or a thick iron plate in order to stably support the sign board, so that it has a problem that it is heavy, difficult to carry, and takes up storage space. is there.

[0003] For this reason, the present applicant has previously filed Japanese Patent Application No. 6-33.
No. 0251 proposes a lightweight and foldable self-luminous sign device. In this sign device, a sheet having flexibility and air permeability is used as a base material, and a plurality of light emitting units are attached to the sheet to form a predetermined sign pattern. If this sign device is used, the sign can be reduced in weight, so that a pole, a base, etc. supporting the sign can be also reduced in weight, and it can be easily carried by folding and is advantageous in storage.

[0004]

However, in the above-mentioned proposals, the sheet must be formed in a mesh structure or a porous structure in order to impart air permeability to the base sheet. Therefore, the adhesive when attaching the light emitting unit becomes difficult to adhere to the base material,
Adhesion problems arise. For this reason, in the previous proposal, the resin sheet is attached to the base material so as to be sandwiched between the base material and the adhesiveness and the adhesion property to the base material are enhanced. However, the number of components is increased. In addition, because the light reflectance of the base material itself is low, the visibility of the base material is low when the sign device is actually used, and the visibility of the entire sign device may be reduced depending on the environmental situation in which the sign is installed. is there.

[0009]

Next, the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of one embodiment in which the present invention is applied to a road sign. A flexible sheet 1 is formed in a horizontally long rectangle, and a required reflection pattern sheet is formed on the surface of the sheet.
Here, a reflective pattern sheet 2 composed of three arrows pointing in the horizontal direction is formed, and a light emitting unit 3 that emits light linearly along the center line of the reflective pattern sheet 2 is attached. In addition, metal rings 4 are integrally attached to six places along the sides of the flexible sheet 1 so that the sign device can be hooked on a support base, a pillar, or the like described later using the metal rings 4. Make up. A cord 5 is led out from one side of the flexible sheet 1, and a connector 6 connected to a power source (not shown) for causing the light emitting unit 3 to emit light is connected to a tip of the cord 5.

The flexible sheet 1 is formed of a sheet material having a high bending resistance and a high light reflectance on the surface.
It is made by coating resin material such as vinyl chloride resin. Since this sheet material is made of a polyester base fabric, it has high durability against repeated bending, has glossiness due to the resin coated on its surface, and is easy to reflect light. Here, two white sheets are piled up and their peripheral edges are sewn together to form a rectangular flat bag.

The reflection pattern sheet 2 provided on the surface of the flexible sheet is obtained by cutting out a sheet material having a high light reflectance, and an adhesive 7 is applied to the surface of the flexible sheet 1 (see FIG. 3).
It is bonded and fixed. Here, the same material as the sheet material of the flexible sheet 1 is used as the reflection pattern sheet 2, the red sheet material is cut out in an arrow-shaped pattern, and three arrow-shaped patterns are arranged in a horizontal line. ing. Then, on the surface of the reflection pattern sheet 2,
The light emitting unit 3 is adhered along the center line of each arrow-shaped pattern with an adhesive 8 (see FIG. 3).

The light-emitting unit 3 has an elongated strip shape having a semi-cylindrical cross section made of an elastic synthetic resin material such as urethane rubber, as shown in a perspective view with a part broken away in FIG. 2 and a sectional view taken along the line AA in FIG. An opening groove 32 whose width is increased inwardly is formed on the upper surface along the longitudinal direction of the body 31, and the bottom surface of the opening groove 32 has some flexibility. And elongated circuit board 3
3 are stored. On the surface of the circuit board 33, a plurality of light emitting elements 3 such as light emitting diodes and light emitting diode chips are provided.
4 are arranged at substantially equal intervals, and are electrically connected by the circuit board 35. The opening groove including the circuit board is filled with a transparent resin 35 such as milky white silicon, and the transparent resin 35 supports the circuit board 33 in the opening groove 32, and the upper surface of the transparent resin 35 is circular. By forming it in an arc shape, the transparent resin 35 itself is configured to function as a lens of the luminous body.

The lead wire 36 connected to the circuit board 33 is made of a flexible wire,
Is pulled out from one end. The lead wire 36 is drawn into the inside of the flexible sheet 1 through the hole 11 provided in a part of the surface of the flexible sheet 1, and after the lead wires of each light emitting unit are electrically connected to each other, It is connected to the cord 5 pulled out from the flexible sheet. In this case, the respective lead wires 36 of the plurality of light emitting unit 3 are connected to the flexible sheet 1 as used in the earlier application.
The connection can be made by a relay board or a power distribution component (not shown) provided inside.

Here, the body 3 of the light emitting section unit 3
1 uses the same red material as the reflection pattern sheet 2, and when adhered to the surface of the reflection pattern sheet 2,
The body 31 and the reflection pattern sheet 2 are configured so that they appear completely integrated in appearance. Further, the light emitting unit 3 is configured such that each light emitting body 34 emits light by energizing each light emitting body 34 through the circuit board 33, and the emitted light is emitted to the upper surface side of the body 31 through the transparent resin 35, At this time, since the upper surface of the transparent resin 35 has an arc shape, the light can be made into parallel light or light can be emitted in a diffused state, and as a result, it functions as a linear light source along the opening groove 32. become.

Therefore, according to this marking device, the surface of the flexible sheet 1 is coated with a resin, so that the flatness thereof is high. Therefore, even when the reflection pattern sheet 2 is directly adhered to the flexible sheet 1, , High adhesive strength can be obtained. For this reason, a resin sheet as a base film like the one proposed by the present applicant is unnecessary, and the number of components can be reduced.

On the other hand, when this sign device is used as a sign, as shown in FIG. 4 (a), the flexible sheet 1 is expanded, and is constituted by a support and a horizontal frame, thereby forming a road. The metal rings 4 provided at six places of the flexible sheet 1 are attached to hooks 101 provided on a support frame base 100 erected on the portion directly or via a ring 102 as shown in the drawing. As a result, the marker device is supported by the support frame 100 in a state where the surface is expanded. In this state, the surface of the flexible sheet 1 is white and has high reflectance, and thus functions as a reflection plate. Then, the light of the headlight of the automobile is reflected or the external light is reflected, so that the entire flexible sheet 1 looks bright and the visibility at night is improved. Similarly, since the reflection pattern sheet 2 also has a high reflectance, it functions as a reflection plate, and the visibility is improved as a red arrow.

In addition, when the light emitting section unit 3 emits light, a linear light emission is performed along the center line of the reflection pattern sheet 2, and the direction of the arrow is displayed. This display is effective especially for a pedestrian who does not have a light even when the flexible sheet 1 and the reflection pattern sheet 2 are not irradiated with external light. Further, when the light emitting unit 3 emits light, a part of the light is irradiated on the reflection pattern sheet 2 and the flexible sheet 1 to illuminate them, thereby enhancing the display effect. is there.
In particular, since the light emitting unit 3 is disposed along the center line of the arrow-shaped pattern constituting the reflection pattern sheet 2, the portion along the center line of the reflection pattern sheet 2 becomes brightest, and from there, both width directions Since the lighting is performed even when the camera is directed to the camera, a unique display effect can be obtained.

On the other hand, when the marking device is not used, as shown in FIG. 5A, the flexible sheet 1 is formed so as to include one of the three reflection pattern sheets 2 on one side. Fold approximately 1/3 of the part. Then, another approximately 1/3 of the flexible sheet 1 is overlapped and folded so as to include the reflection pattern sheet 2 on the other side, so that the entire marker device is reduced to 1/3 as shown in FIG. It can be folded to size and downsized. Therefore, by storing or transporting in this state, the handling of the marking device can be made extremely simple.

Since the lead wire 36 is made of a flexible wire, it does not hinder the folding of the flexible sheet 1. Further, the light emitting unit 3 includes a body 31.
The light emitting unit 3 can also be curved in its length direction because the light emitting unit 3 is provided with some flexibility. It is also possible to store it in a state of being rolled up from one end side.

Here, in the present invention, as shown in FIG. 4 (b), the reflection pattern sheet to be attached to the surface of the flexible sheet is a different pattern 2A, and light is emitted at a position along the center line of the reflection pattern sheet. By providing the unit 3, it can be configured as a marker for a different reflection pattern sheet 2 </ b> A. Also in this case, by folding the flexible sheet 1, the marking device can be downsized when not in use.

In the above embodiment, the configuration example in which the reflection pattern sheet is provided is shown. However, the light emitting unit 3 is directly adhered to the surface of the flexible sheet 1 and the display is performed only by the light emission in the light emitting unit 3. It is also possible to configure to perform the following. Also in this case, since the flexible sheet 1 has a high reflectance, the visibility can be enhanced and the display effect in the light emitting unit 3 can be enhanced. Also in this case, since the flexible sheet 1 has high surface flatness, a high adhesive force can be obtained even when the light emitting unit is directly adhered to the flexible sheet without using a base film.

Further, in order to connect the light emitting unit to a power source, in the above-described embodiment, the cord 5 is pulled out from the flexible sheet 1 and the connector 6 is connected.
A connector may be directly attached to a part of the connector, and an external connector connected to a power supply may be configured to be detachable from the connector. In this case, since the cord is not pulled out from the flexible sheet, the handling at the time of storage can be further facilitated.

Thus, light from the light emitting unit and external light are reflected with high efficiency, the visibility of the flexible sheet is increased, and the visibility of the entire sign device is improved. In addition, resin core on the surface of the flexible sheet
Since the surface of the coating is flat, the adhesiveness of the reflection pattern sheet and the adhesiveness of the light emitting unit thereon are improved, and components such as a resin sheet become unnecessary, which is effective in reducing the number of components.

Further, according to the present invention, the flexible lead wire electrically connected to the light emitting unit is inserted into the internal space of the flexible sheet through a hole formed in the surface of the flexible sheet. The appearance of the lead wire does not deteriorate, and the flexibility of the lead wire does not hinder the folding of the flexible sheet.

Further, according to the present invention, by providing a reflection pattern sheet around the light emitting unit, the light emitted from the light emitting unit and the external light are effectively reflected by the reflection pattern sheet so that the visibility of the sign pattern is improved. Can also be increased.

Further, since the light emitting unit is mainly composed of a slender and flexible body, the light emitting unit can be folded or wound up together with the flexible sheet, so that the sign device can be used. The storability can be improved.

Further, by forming the body of the light emitting unit in the same color as the reflection pattern sheet, a sense of unity in appearance between the reflection pattern sheet and the light emitting unit is enhanced, and the appearance of the sign device is improved. It is also possible.
