[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 up from one end side and stored, but if the winding diameter is small, a bending force is applied to the light emitting unit and the relay board, and it is impossible to reliably prevent such damage. Can not.

Further, in a state where the marking device is actually used, the bending of the sheet due to the wind or the like due to the air permeability of the sheet is reduced, but it is difficult to completely prevent this. In particular, when the sheet is used in a vertically hung state, the lower edge of the sheet is easily lifted by the wind,
It becomes difficult to ensure the flatness of the sheet, and as a result, the visibility of the marker pattern formed by the light emitting unit arranged on the sheet surface is likely to be reduced.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the problems inherent in the above-described sign device, to enable storage without damaging the sign pattern, and to reduce visibility due to bending of the sheet during use. It is to provide a marker device which has improved.

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 liquid-tight 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 core. 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 the respective patterns 3 and 4 are formed due to the difference in inner and outer circumferential dimensions during winding.
May be stressed, and these may be wrinkled. However, in this embodiment, the liquid-tight spaces 33, 43 defined by the transparent resin sheets 41, 42, 32 and the sub-sheet 31 are made larger than the outer dimensions of each of the patterns 3, 4, so that FIG. Since the character pattern 4 is freely moved in the liquid-tight space 43 as shown in a part of the character pattern 4, the stress can be relieved particularly by movement in a plane direction, and the character pattern 4 is bent. Is avoided. This is the same for the arrow pattern 3.

In this embodiment, the arrow pattern 3
Is provided on the flexible sub-sheet 31, and the sub-sheet 31 is detachable from the main sheet 1, so that the male hook 13 and the female hook 35 are removed as shown in FIG. The male hook 13 and the female hook 3 are rotated again 180 degrees in the plane direction and turned left and right.
By engaging 5, it is also possible to display the arrow pattern 3 in the left and right opposite directions. In this case, the lead wire 9 is twisted, but this does not cause any problem.

Here, in the above embodiment, the character pattern 4
To hold the main sheet 1
Although the transparent resin sheets 41 and 42 are disposed on the front side and the rear side of the main sheet 1, the transparent resin sheet 42 on the rear side may be disposed on the front side of the main sheet 1 as shown in FIG. That is, a pair of transparent resin sheets 41 and 42 are welded at the peripheral edge thereof to define a liquid-tight space 43, and the character pattern 4 is provided in this space, and the transparent resin sheet 42 on the back side is provided.
May be fixed to the main sheet 1. In this case, the method of fixing the transparent resin sheet 42 to the main sheet 1 is the same as that of the above-described embodiment.
A method of welding the peripheral portion of the main sheet 1 to the main sheet 1 can be adopted. Alternatively, bonding with a resinous adhesive can also be used.
In this configuration, the character pattern 4 and the transparent resin sheet 4
Since a manufacturing procedure of forming a structure composed of 1, 42 in a separate step and integrating it with the main sheet 1 in a later step can be adopted, it is more effective than the structure of the above embodiment in terms of manufacturing workability. . 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. Also, 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.

Here, various mesh structures of the main sheet 1 can be used.
The mesh type shown in (a) 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,
Since the triangular type does not collapse in the mesh shape even with respect to the tensile force at the periphery of the mesh, the tensile force can be prevented from being affected by the sign pattern 2, and the sign pattern 2 is deformed. Further, the marker pattern 2 or the transparent resin sheets 41 and 42 and the sub-sheet 31 are prevented from being peeled off from the main sheet 1.

In the above-described embodiment, the power cord 20 is pulled out from the cap 16 of the main shaft 15 and the connector 21 is connected. However, the connector is directly provided on the cap 16 and the external connector connected to the power cord is connected to this connector. You may comprise so that attachment and detachment are possible to a connector. In this way, the power cord is not pulled out of the sign device,
The convenience of handling during storage can be improved.

Further, the main shaft 15 at the lower side of the main seat is provided.
May be a solid circular axis, a cylindrical axis with a polygonal cross section, or a solid axis. However, in the case of a solid shaft, a concave portion or a through hole may be formed in a part of the solid shaft, a power supply circuit board may be provided inside the concave portion, and a power cord may be inserted into the through hole. Further, the auxiliary shaft 18 at the upper part of the main seat is not limited to a circular shape, but may be a cylindrical shaft or a square shaft. Alternatively, when a horizontal bar exists between the columns on which the main seat is installed and the upper portion of the main sheet can be locked to the horizontal bar, the auxiliary shaft of the upper portion may be omitted.

[0026]

As described above, according to the present invention, the shaft is provided on one side of the main sheet to which the flexible self-luminous sign pattern is attached, so that the main sheet is wound around the shaft. By taking it, it can be stored.
Thus, since the main sheet is wound up with a curvature according to the diameter of the shaft, the self-luminous sign pattern is prevented from being extremely bent and damaged. In addition, by disposing the shaft portion on the lower side of the main sheet, the shaft portion functions as a weight in a state where the marking device is installed, and the main sheet is kept flat to make it easier to see the display of the sign pattern. It is possible to suppress the main sheet from being lifted by wind or the like.
