DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sign device used for regulating traffic during road works and accidents, and regulating traffic for vehicles and pedestrians, and more particularly to a self-luminous sign formed in a required pattern. The present invention relates to a marker device having a configuration in which a pattern is arranged on a flexible sheet to enable winding and storage.

[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. For this reason, the present applicant has previously proposed a light-weight and foldable self-luminous sign device in Japanese Patent Application No. Hei 6-330251. 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.

[0003]

However, in the prior proposal, when the sheet is folded during carrying or storage, the sheet may be bent at the light emitting unit, and the light emitting unit and the relay board for connecting the power supply may be folded. There is a possibility that the light emitting unit and the relay board may be damaged due to the application of external force. For this reason, it has been proposed that the sheet be wound and stored from one end side, but when the light emitting unit is bent together with the sheet during winding, a bending force is generated in the light emitting unit, and the light emitting unit is moved in the same manner as described above. You will be damaged.

From this, it is conceivable that the light emitting unit is configured as a sign pattern in which the light emitting unit is formed on a flexible sheet, for example, a flexible printed circuit board. However, even when the sign pattern is provided with flexibility, if the sign pattern is integrally attached to the sheet, the sheet or the sign pattern may vary depending on the inner and outer radius difference between the sheet and the sign pattern when the sheet is rolled up. Any of the low rigidity sides of the sign pattern may be loosened or a tensile force may be applied. And, when the rigidity of the sign pattern is lower than that of the sheet, if such a bend or tension occurs in the sign pattern, the thin film circuit pattern provided on the printed circuit board is broken due to breakage or tensile force, There is a possibility that the sign pattern may be in an electrically inoperable state.

[0005] An object of the present invention is to solve the problem that occurs when such a flexible sign pattern is employed, and to provide a sign device that can be stored without damaging the sign pattern. .

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of an embodiment in which the present invention is applied to a road sign, FIG. 2 is a front view thereof, and FIG. 3 is a side view. A mesh-shaped main sheet 1 having stitches or a large number of pores, and having breathability, ventilation and flexibility.
Is formed in a predetermined dimension, for example, a rectangle of 1 m × 1 m in length and width,
A self-luminous sign pattern 2 formed in a required pattern on one surface of the main sheet 1, an arrow pattern 3 in which three laterally oriented arrows are arranged, and "under construction"
Are arranged at respective positions in the vertical direction of the plane of the main sheet 1 and fixedly supported. In this embodiment, the character pattern 4 is provided directly on the main sheet 1, but the arrow pattern 3 is provided on a flexible sub-sheet as described later. The sub-sheet is detachable from the main sheet 1. Thus, the arrow pattern 3 is configured to be mounted on the main sheet 1 with the direction of the arrow pointing in one direction or the opposite direction.

The self-luminous sign pattern 2 composed of the arrow pattern 3 and the character pattern 4 is shown in FIG.
As shown in the example, an amber reflective sheet 6 having a high light reflectance is attached to the surface of an FPC board (flexible printed circuit board) 5 in which a thin film conductor is formed in a required pattern on a flexible insulating board. These FPC boards 5
And the reflection sheet 6 are cut out in an arrow shape.
At this time, the reflection sheet 6 is provided with windows 6a at a plurality of positions along the center line of the arrow shape, and a chip type light emitting diode 7a and a resistor 7b are provided on the surface of the FPC board 5 exposed in the window 6a. Etc. are mounted and electrically connected by the thin film conductor 8. And the FPC board 5
A lead wire 9 is connected to the thin film conductor 8, and a plurality of arrow patterns 3 are electrically connected to each other by a lead wire, and are connected to a power supply circuit described later. Note that the character pattern 4 is also configured in the same manner as the arrow pattern, except that the reflection sheet is formed in red and the character pattern “under construction” is formed as described above.

Here, the three character patterns 4 constituting the "under construction" self-luminous sign pattern are arranged in a horizontal line as shown in FIG.
As shown in FIG. 5A, the cross-sectional structure along the line A is covered with a transparent resin sheet 41 made of polyethylene or the like patterned along the contour of the character pattern 4 so as to cover the front surface of the character pattern 4. A similar transparent resin sheet 42 is also arranged on the back surface side.
The peripheral portions 1 and 42 are integrally welded with the main sheet 1 sandwiched therebetween. Therefore, a liquid-tight space 43 is defined between the front and rear transparent resin sheets 41 and 42 as support sheets, and a part of the main sheet 1 and the character pattern 4 are sealed in the liquid-tight space. State
Waterproofness against rainwater and the like is ensured. In this case, the outer dimensions of the transparent resin sheet are slightly larger than the outer dimensions of the character patterns, and each character pattern 4 is configured to be accommodated in the hermetic space 43 with a margin particularly in the parallel direction. In addition, as shown in FIG. 2, the lead wire 9 connected in series to each character pattern is drawn out from between a part of the transparent resin sheets 41 and 42.

On the other hand, the arrow pattern 3 corresponds to BB in FIG.
As shown in FIG. 5B, the line cross-sectional structure is supported by the sub-sheet 31 made of thick vinyl chloride or the like which has flexibility as described above and has a relatively large surface light reflectance. . The three arrow patterns 3 are arranged in a horizontal row as shown in FIG. 2, and are covered with a transparent resin sheet 32 of polyethylene or the like patterned along the outline so as to cover these front faces, Then, the periphery of the transparent resin sheet 32 is integrally welded to the surface of the sub-sheet 31. Therefore, a liquid-tight space 33 is defined by the sub-sheet 31 and the transparent resin sheet 32, and the liquid crystal space 33 is in a state where the arrow pattern 3 is sealed. in this case,
The outer dimensions of the transparent resin sheet 32 are made larger than the outer dimensions of the arrow patterns 3, and each of the arrow patterns 3 is configured to be accommodated in the liquid-tight space 33 with a margin particularly in the planar direction. The lead wire 9 connected to each arrow pattern 3
Is pulled out from the back side of the sub-sheet 31 as shown in FIG. 1 and is held in a state of being adhered to the main sheet 1 by a fixing tape 34 or the like. At the six peripheral edges of the sub-sheet 31, resin-molded female hooks 35 are attached. The female hooks 35 can be attached to and detached from the main sheet 1 by using the female hooks 35 as described later. Configuration.

The main sheet 1 is formed by coating a resin material having a relatively low melting point, such as a vinyl chloride resin, on a mesh in which fibers having a high melting point, such as polyester, are woven. The chemical strength is increased and the chemical strength under the influence of rainwater, exhaust gas and the like is increased. As shown in FIGS. 1 to 3, a sheet band 11 made of vinyl chloride, polyethylene, or the like is extended around the periphery of the main sheet 1 so as to cover the edge thereof. Is welded to and integrated with the main sheet 1 to form a fringe portion 11 that covers the peripheral side portion of the main sheet 1. A circular fixed ring 1 is provided at a plurality of locations of the fringe portion 11.
2 is used to fix and to insert a string or wire when installing the marking device. Male hooks 13 are fixed to the sub-sheet 31 provided with the arrow pattern 3 at six locations corresponding to the female hooks 35.
By fitting the female hook 35 with the sub-seat 3
1 is configured to be fixedly supported on the main sheet 1. The lead wire 9 pulled out from the sub-sheet 31 is inserted into the fringe portion 11 at a part of the fringe portion 11.

A pair of wide sheet strips 14 made of the same resin material as the sheet strips constituting the fringe portion 11 are provided on the lower side of the main sheet 1 so as to face each other and extend along the lower side. The upper and lower edges of these wide sheet strips 14 are welded to face each other to form a tubular shape. The cylindrical main shaft 15 is inserted into the inside of the cylindrical shape. The main shaft 15 is slightly heavier in weight, and its outer diameter is set as large as possible within a range not bulky when the main sheet 1 is wound as described later.

The main shaft 15 is covered with circular caps 16 at both ends, and the inside is sealed. A power supply circuit board 10 for illuminating the light emitting diode 7a provided on the marker pattern 2 is provided inside the main shaft 15. ing. Then, the lead wires 9 respectively drawn out from the character pattern 4 and the arrow pattern 3 are inserted through holes 15a opened in a part of the main shaft 15 in a state where waterproofness is maintained by a rubber bushing or the like (not shown), The power supply circuit board 10 is connected. Also, the power cord 2 connected to the power circuit board 10
0 is drawn out through a hole 16a provided in the cap 16 while maintaining waterproofness, and a connector 21 is connected to a distal end thereof.

Similarly, a pair of wide sheet strips 17 are arranged on the upper part of the main sheet 1 so as to face each other, and the upper edge and the lower edge are welded to each other to form a cylinder. An auxiliary shaft 18 composed of a circular shaft is inserted in the inside of the shape. The auxiliary shaft 18 has a solid shape, and has an outer diameter smaller than that of the main shaft 15 within a range having a strength such that the auxiliary shaft 18 is not extremely bent. Further, of the pair of wide sheet bands 17, a protective sheet 19 formed on the back surface of the wide sheet band on the back side is formed to be somewhat longer than the outer peripheral length when the main sheet 1 is wound as described later. One side is integrally connected. The protective sheet 19 is formed of a cloth such as cotton or chemical fiber, and one edge of the protective sheet 19 is formed of the wide sheet band 17.
And one side of the one edge and the other edge is detachable coupling means, for example, a tape composed of one group of micro hooks and the other group of loop fibers. A coupling means (not shown) such as a structured product name “Magic Tape” is attached.

In this embodiment, the main seat 1
A plurality of circular fixed rings 1 are also provided on the outer edges of the wide sheet strips 14 and 17 provided on the upper portion and the lower portion, respectively.
2 are provided.

Therefore, when the sign device is actually installed, as shown in FIG. 6, the main sheet 1 is hung in a state where the main sheet 1 is spread between two pillars 100 erected on a part of the road. Let it. At this time, for example, the fixed ring 12 of the main sheet 1 is attached to the hook 101 provided on the support column 100 directly or via a ring (not shown). As a result, the sign device is supported between the columns 110 with the main sheet 1 expanded and in a substantially vertical plane. In this state, since the auxiliary shaft 18 exists along the upper portion of the main seat 1 and the main shaft 15 exists along the lower portion, the main seat 1 is moved upward by the auxiliary shaft 18 and the main shaft 15. And the lower side are held in a straight line, so that the surface is kept flat. In particular, on the lower side, the weight of the main shaft 15 functions as a weight and the main seat 1
In order to apply a downward tensile force to the surface, the flatness of the surface becomes high. And even when the strong wind hits the main sheet 1, the flatness of the main sheet 1 especially
5, the shape is held, so that the shape is not lifted, and the shape is securely held.

When power is supplied to the self-luminous sign pattern 3 through the power cord 20, the light emitting diode 7a
Is emitted. At the same time, since the reflection sheet 6 of the self-luminous sign pattern 2 reflects the light of the headlight of the car or the outside light of the streetlight, the sign pattern is displayed, and the driver of the car is presented to the driver. This makes it possible to recognize the sign. The light emission of the light emitting diode 7a can be controlled by the power supply circuit board 10 to emit light in any form such as continuous light emission, blinking, and sequential light emission. In addition, since each light emitting diode 7a is disposed along the center line of each of the patterns 3 and 4 of the arrow or character formed by the reflection sheet 6, the portion along the center line of the reflection sheet 6 becomes brightest. Since the reflective sheet surfaces in the regions in both width directions are illuminated therefrom, a unique display effect can be obtained.

On the other hand, when the marking device is not used, as shown in FIGS. 7A and 7B, the main sheet 1 is moved from the lower part to the upper part with the main shaft 15 provided at the lower part as a center. You can wind it up. Then, after winding up to the upper part, the protective sheet 1 is wrapped around the whole including the main shaft 15 and the auxiliary shaft 18.
By winding around 9 and joining one edge to the other edge, it is possible to store the marker device. At this time,
Since the outer diameter of the main shaft 15 is designed to be relatively large, each of the patterns 3 and 4 of arrows and characters is bent into a cylindrical surface when the main sheet 1 is wound up. Since the outer diameter of the main shaft 15 is not made smaller, the patterns 3 and 4 are prevented from being damaged by bending. In particular, in this embodiment, each pattern 3,
An FPC board 5 is used for the FPC board 4. The FPC board 5 has a thin film conductor that is easily broken by bending, but the bending curvature is limited, so that breakage is effectively prevented.

When the main sheet 1 is wound on the main shaft 15, the transparent resin sheets 32, 41 and 42 are present on the front surface or the front and back sides of the self-luminous marker pattern, and the sub-sheets are provided on the back side. 31 and the main sheet 1 are present, the thickness thereof is larger than that of other portions, and stress is applied to each of the patterns 3 and 4 due to a difference in inner and outer circumferential dimensions at the time of winding. Bending may occur. However, the transparent resin sheets 41, 4
2, 32 and the liquid-tight space 33 defined by the sub-sheet 31,
Since 43 is larger than the external dimensions of each of the patterns 3 and 4, as shown in FIG.
Since the character pattern 4 is freely moved in the liquid-tight space 43, the stress can be released particularly by movement in the plane direction, and the character pattern 4 is prevented from being bent. This is the same for the arrow pattern 3.

Particularly, in this embodiment, the arrow pattern 3
Is provided on the flexible sub-sheet 31 and the sub-sheet 31 is attached to the main sheet 1. Therefore, when the main sheet 1 is wound, the arrow pattern 3 on the sub-sheet 31 The difference in radius between the main sheet 1 and the character pattern 4 directly attached to the main sheet 1
However, since the arrow pattern 3 is moved in the liquid-tight space 33 between the sub-sheet 31 and the transparent resin sheet 32 as described above, the arrow pattern 3 is wrinkled like the character pattern 4. Is not generated.

Since the sub-sheet 31 supporting the arrow pattern 3 is detachable from the main sheet 1, the male hook 13 and the female hook 35 are provided as shown in FIG.
Is removed, the sub-sheet 31 is rotated 180 degrees in the plane direction, and the male hook 13 and the female hook 35 are again engaged in a state where the left and right sides are reversed, so that the arrow pattern 3 is displayed in the left and right opposite direction. It is also possible. In this case, the lead wire 9 is twisted, but this does not cause any problem.

Here, as a structure of a support sheet for holding the self-luminous sign pattern 2 on the main sheet 1,
In the above embodiment, the transparent resin sheets 41 and 42 are provided on the front side and the back side of the main sheet 1, but the transparent resin sheet 42 on the back side is disposed on the front side of the main sheet 1 as shown in FIG. It may be arranged. That is, the pair of transparent resin sheets 41 and 42 are welded at their peripheral portions to form a liquid-tight space 4.
3, the character pattern 4 may be provided in this space, and the transparent resin sheet 42 on the back side may be fixed to the main sheet 1. In this case, the transparent resin sheet 4
As a method of fixing the second resin sheet 2 to the main sheet 1, a method of welding the peripheral portion of the transparent resin sheet 42 to the main sheet 1 can be adopted as in the above embodiment. Alternatively, bonding with a resinous adhesive can also be used. In this configuration, a manufacturing procedure of forming a structure including the character pattern 4 and the transparent resin sheets 41 and 42 in a separate process and integrating the structure with the main sheet 1 in a subsequent process can be adopted, and therefore, the workability of the manufacturing is improved. Is more effective than the structure of the above embodiment. Even in this configuration, it is important that the dimensions of the liquid-tight space 43 be slightly larger than the outer dimensions of the character pattern 4 so that the character pattern 4 can move in the liquid-tight space 43. When the arrow pattern 3 is directly installed on the main sheet 1 like the character pattern 3, the same configuration as the character pattern 4 can be adopted.

In the character pattern 4, the transparent resin sheet 42 on the back side does not need to particularly expose the sign pattern, and may be formed of a non-transparent resin sheet. In the arrow pattern 3, the sub-sheet 3
1 may be disposed on the back side of the main sheet 1 and welded to the transparent resin sheet 32 on the front side. Also in the configuration of FIG. 10, it is important that the dimensions of the liquid-tight space be slightly larger than the outer dimensions of the self-luminous sign pattern so that the sign pattern can move in the liquid-tight space. .

Here, the main sheet does not have a mesh structure, but may be a general flexible sheet, for example, a non-transparent sheet used in the sub-sheet of the above embodiment. In the case of forming a mesh sheet, various mesh structures can be used. In the above embodiment, a mesh type as shown in FIG. 11A is employed. On the other hand, a mesh structure such as a triangle type as shown in FIG. 11B and a honeycomb type as shown in FIG. 11C can be adopted. In particular, the triangular type does not collapse in the mesh shape even for the tensile force around the mesh,
This tensile force can be prevented from being influenced by the sign pattern 2, the sign pattern 2 is deformed, and further, the sign pattern 2 or the transparent resin sheets 41 and 42 and the sub-sheet 3
1 is prevented from being peeled off from the main sheet 1.

[0025]

As described above, according to the present invention, the flexible self-luminous sign pattern attached to the main sheet is disposed along the front and back surfaces, and the periphery thereof is sealed.
Seal between a pair of support sheets that are transparent on at least the front side
Inside the closed space, and the dimension in the plane direction inside the sealed space
Method is set larger than the external dimensions of the self-luminous sign pattern
The main sheet is provided so as to be relatively movable in the plane direction with respect to the main sheet, so that when the main sheet is rolled in when the marker device is stored, a dimensional difference in the radial direction occurs between the main sheet and the marker pattern. In this case, it is possible to prevent a bending force from acting on the marker pattern, thereby preventing the marker pattern from being damaged. In addition, since the sign pattern is provided inside the sealed space defined by the pair of support sheets, the waterproofness and dustproof property of the sign pattern can be secured, and the reliability of the mark pattern can be secured.
