DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in emergency sites such as traffic accidents and road surface construction, and is used for center lines, lane change lines, and separation zones on roads to safely and easily regulate road traffic zones. For road signposts.

[0002]

2. Description of the Related Art As a simple sign for regulating a traffic lane on a road, a conical sign formed in the shape of a pilgrimage is conventionally known. In the case of this conical sign, in order to enhance the transportability, it is formed into an internal hollow shape with a plastic material or the like to reduce the weight, and a large number is overlapped during transportation. The outer surface is decorated with red and white stripes to enhance the visibility of passers-by. By the way, in the case of such a plastic conical sign, it is disadvantageous that the weight is reduced in consideration of the transportability, and the sign falls or moves due to a slight natural wind or vibration during use on the road. Or there is a defect. In addition, in terms of transportation, this can be loaded on a vehicle in an overlapping state, but in an emergency vehicle, it is necessary to load a lot of other emergency supplies, and there is only extra flat and narrow space So it cannot be loaded.
Also, because it is bulky, it can get in the way in many ways.

In order to solve the problem of such a conical sign, the present applicant has previously proposed a road sign excellent in transportability and usability (Japanese Patent Laid-Open No. 5-222710).
This road sign can be folded into a single flat plate when stored or transported from the usage state in which it is raised into a pyramid shape, thereby greatly improving the convenience during transport and use.

Each of the above-mentioned road signs has a pair of left and right sign portions on both mountain-shaped slopes rising up in a pyramid shape by a folding structure. For example, an arrow mark or the like indicating a direction is displayed. Therefore, by reflecting the light with the headlights radiated by the traveling vehicle at night, the visibility of the instruction mark of the driver is enhanced, and the vehicle can be guided safely.

By the way, in the case of such a reflection type sign display, a driver who is driving at night, in particular, can visually recognize the sign display only when the sign display is irradiated with a headlight and reflected. For this reason, confirmation may be instantaneously delayed, and there is a problem that it is necessary to solve this.

[0006] For example, as a solution to this, Japanese Utility Model 5-3
As shown in the display device of JP-A-8392, there is a display device in which an LED lamp is lit and displayed instead of the reflective sign.
Such a lighting display method of the LED lamp is effective in that the driver of the running vehicle can check the lighting display even from a considerable distance, thereby improving visibility.
However, in spite of such effects, the display device of the Utility Model Publication has another structure, in which air is sealed in a sheet during installation to maintain the shape of the sign. However, there is a drawback that the air filling operation is troublesome and troublesome. This lacks quick assemblability during use and causes a delay in response in an emergency.

On the other hand, it can be said that when the sign display is a figure such as an arrow mark, the driver visually recognizes the figure and judges the meaning of the display. On the other hand, in the case of characters, it can be read directly to determine the meaning of the display,
This is effective in making the driver understand the meaning of the sign display instantly. In this sense, further visibility can be expected by using a structure in which the display using “characters” and the lighting method using the LED lamp described above are combined.

[0008]

SUMMARY OF THE INVENTION An object of the present invention is to improve the transportability and the usability, and to improve the visibility from a distant place, particularly during nighttime driving, so that the display can be instantly understood. The goal is to provide a safe and simple road sign that satisfies all the conditions.

[0009]

A road sign according to the present invention has a pair of bottom substrates that can be folded and folded from the center and a pair of sign plates that can be folded and folded flat from a mountain shape. On each side edge, each skirt end of the sign board is connected so as to be overlapped and foldable, and in a road sign that can be folded into a flat plate shape from the whole pyramid-shaped assembly state, a large number of light emitting elements are provided on the surface of the sign board. They are arranged and displayed in predetermined characters or figures, and are configured to light or blink, preferably blink.

[0010]

[Function] Since the light emitting elements such as LEDs (light emitting diodes) are mounted in a row along the character display of the sign,
By turning on or off the light-emitting element, the driver of a vehicle traveling at night in particular can instantly confirm the display even from a long distance. In addition, when using the sign, when the bottom substrate and the sign plate are opened, this opening action causes the pressure-sensitive switch sensor
The switch of the switch is released , and the power is turned on. When folded and stored, when the bottom substrate and the sign board are folded and closed, the closing operation pushes in the contact of the limit switch and turns off the power. That is, the time for turning on and off the power switch at the time of installing and storing the sign is omitted, and the light emitting element is automatically turned on and off.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a road sign according to the present invention will be described below with reference to the drawings. FIG. 1 is an assembled perspective view of a road sign according to an embodiment, and FIGS. 2 to 5 show an assembled front view, an enlarged view of a main part, a rear view, and a side view. As shown in the figure, a sign 10 that is raised in a pyramid shape in a folding structure has a pair of left and right bottom substrates 11, 11, and the pair of bottom substrates 11, 11 is connected to a hinge sheet 12 so as to be folded outward. Have been. On the bottom substrates 11, 11, a pair of sign plates 13, 13 forming both mountain-shaped slopes from these ends are also foldably connected.

For the bottom substrate 11, for example, a vinyl chloride resin plate having a thickness of about 10 mm is used. For the hinge sheet 12, for example, a vinyl chloride resin sheet containing a base cloth is used. Left and right bottom substrate 1
1 and 11 can be bent outside. For the bottom substrate 11, chloroprene rubber, urethane rubber, or the like can be used in addition to the vinyl chloride resin.

In the embodiment, a semi-rigid vinyl chloride resin plate is used as the pair of sign plates 13 and 13. The sign plate 13 is foldably connected by a hinge sheet 14 at the top portion of the chevron. The reflection sheet 15 in the shape of an arrow such as white indicating the direction is
To enhance daytime visibility. In addition, characters, rectangles, and the like may be displayed in black and displayed on a yellow non-reflective sheet that is not reflected by daylight or night headlight.

As described above, the sign 10 is composed of the pair of left and right bottom substrates 11 and 11 and the four plate members consisting of the sign plates 13 and 13, and when assembled into a pyramid shape, the corner portion which becomes a ridge line. May be used, for example, in addition to the above-described base cloth-containing vinyl chloride resin sheet having a thickness of about 0.2 to 0.5 mm, a sheet made of polyurethane rubber, or the like. This is easy to join by heat fusion by high frequency, and has a strong joining strength and excellent durability even when folding is repeated. However, the hinge sheets 12 and 14 may be made of urethane rubber, instead of vinyl chloride resin containing a base cloth, and vice versa.

Further, as shown in FIG. 2, for example, a character display 16 of "accident" is provided on one side plate 13, which is the front side of the pair of sign plates 13, 13. A non-reflective sheet made of a material that is not reflected by sunlight or headlights is used for the base 17 around the character display 16 so as not to hinder clear recognition of the character display 16.

Here, as shown in FIG.
LED along with the word "accident" in the example
Light emitting elements 18 such as (light emitting diodes) are mounted in a row. The light emitting element 18 can be a lighting or blinking electric circuit. However, as described as a conventional problem, the blinking method is more effective in that it is effective for the gaze of the driver of the traveling vehicle.

The blinking cycle of the light emitting element 18 is preferably in the range of 50 to 250 times per minute, and about 20 to 250 times per minute in terms of effect. One lighting time is preferably about 0.03 to 0.3 seconds.

The structure of the blinking circuit or the lighting circuit of the light emitting element 18 is such that a control box 19 incorporating the circuit is embedded in one of the bottom substrates 11 by utilizing its thickness.
A power supply battery, a power switch for turning the circuit on and off, and the like are housed inside the control box 19, and are connected to the light emitting element 18 via a lead wire 20, as shown in FIG. The light emitting elements 18 are, for example, of a chip type having a forward current of 20 mA and a forward voltage of 2 V. In the case of two characters “accident” as in the embodiment, about 120 pieces are sufficient. Several AAA batteries can be used as the power supply battery.

As the power switch, a limit switch is used as a pressure-sensitive switch sensor according to the present invention. Figure 1 shows the on / off operation when the limit switch is used.
As shown in (1), the switch contact 23 is mechanically set outside the control box 19 so as to be retractable. When the sign is used, when the bottom substrates 11 and 11 and the sign plates 13 and 13 are opened, the opening operation opens the contact 23 of the limit switch and projects from the control box 19 to the outside. turn on. On the other hand, when folded and stored, when the bottom substrates 11 and 11 and the sign plates 13 and 13 are folded and closed, this closing operation causes
3 is pushed into the control box 19, and the power is turned off by this detection. By configuring such a circuit, the trouble of turning on and off the power switch each time the sign is installed and stored can be omitted, and the light emitting element 18 can be turned on and off automatically.

In order to enhance the ease of handling when the sign 10 is installed and stored, in the embodiment, the total weight is suppressed to about 4 to 5 kg, and the handle is located at the optimum position of the sign plates 13, 13 in consideration of the convenience of work. Holes 21 and 22 are provided. Also,
As shown in FIG. 5, the thickness when folded and stored is also 10 to 40 mm.
Because it is a degree, it is easy to load on emergency dispatch vehicles.

If a buzzer or the like for an alarm is set in a control box 19 in which a circuit for turning on or off the light emitting element 18 is incorporated, the sign 1 temporarily set by the wind and rain can be obtained.
When 0 is overturned, an alarm sound is generated to facilitate the restoration.

[0022]

In the road sign according to the present invention, the sign is displayed on a light-emitting element using characters or the like for the purpose of safety, and the driver of a vehicle traveling at night can be used instantaneously even from a long distance. The situation at the accident site can be visually recognized at the same time, and the danger of causing a secondary disaster is eliminated. In addition, since the display by lighting or blinking by such a light emitting element is detected and operated simultaneously and automatically at the time of installation use and folding storage, it can be quickly installed at an emergency site, and furthermore, Because it can be folded compactly, it has excellent transportability and usability.
