Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variable sign capable of switching and displaying two or more meanings, and can be applied to, for example, a traffic sign such as a variable speed regulation sign used on a highway. Is.

[0002]

2. Description of the Related Art Conventionally, as a variable marker of this type, a spiral rotary plate is rotated to position a display plate of the regulation speed in front of a shield plate, thereby switching a plurality of kinds of regulation speeds to a desired regulation speed. There is provided a variable speed regulation sign for displaying a desired speed limit and a variable speed regulation sign for displaying a desired speed limit by rotating a subtitle with a roller to position a desired display described on the subtitle on the front surface.

However, since these variable speed regulation signs have mechanically movable parts, they easily deteriorate.
It had a short life.

Therefore, in recent years, a lightning type variable speed regulation sign as shown in FIG. 15 has been put to practical use on highways and the like. FIG. 15 is a schematic front view showing this conventional variable speed regulation sign. This variable speed regulation sign has a yellow LED
Using, to switch between two types of display patterns: the display pattern of the number "50" indicating that the regulation speed is 50 km / h and the display pattern of the number "70" indicating that the regulation speed is 70 km / h. It is configured to display in yellow. That is, this variable speed regulation sign displays a ring-shaped area 1 along the outer periphery and a display pattern of "50" or "70" in the circular area inside the area 1. A display pattern display scheduled area (the whole of a plurality of small circle areas 2 shown in black in FIG. 15) to be made, and an area 3 inside the ring-shaped area 1 excluding the display pattern display scheduled area. And have. The region 1 is a region colored red with paint or the like, and the region 3 is a region colored black with paint or the like. Each area 2 has multiple yellow LEs.
D is arranged, and the light emitting surface (light emitting area) of the yellow LED (not shown) is provided over almost the entire area of each small circle area 2.

According to this electric variable speed regulation sign,
When displaying that the regulation speed is 50 km / h, the yellow LED of the small circle area 2 forming the display pattern of “50” in all the small circle areas 2 is turned on, and the remaining small circle areas 2 are displayed. Yellow LED is turned off. As a result, "5
The small circle area 2 in which the display pattern of "0" is emitted in yellow and does not form the display pattern of "50" appears black and is assimilated to the black color of the area 3, and together with the area 3, the background of the display pattern of "50". Is displayed in black. Therefore, the regulated speed is not erroneously recognized. When displaying that the regulation speed is 70 km / h, the yellow L of the small circle area 2 forming the display pattern of "70" out of the entire small circle areas 2 is displayed.
It is sufficient to turn on the ED and turn off the yellow LED of the remaining small circle area 2. As described above, the lightning type variable speed regulation sign is preferable because it has no mechanically movable part and thus has a long life.

[0006]

However, in the conventional lightning type variable speed regulation sign, the LEDs in the non-light emitting state are used in order to switch and display a plurality of display patterns.
By utilizing the fact that the light emitting surface of the above, and the like, appears black, the LEDs in the small circle area 2 that do not form the display pattern are turned off when the predetermined display pattern is displayed. Therefore, in order to prevent erroneous recognition of the regulation speed, the background color of the display pattern is limited to black, and there is no freedom in selecting the background color. For example, when the area 3 is white, when the display pattern of "50" is displayed, the small circle area 2 that does not form the display pattern of "50" looks black due to the turning off of the LED and is not assimilated with the area 3. The control speed is mistakenly recognized.

By the way, a normal speed regulation sign which is not a variable type used on ordinary roads is constructed as shown in FIG. In this normal speed regulation sign, the ring-shaped region 11 along the outer circumference is formed of a white reflective sheet, and the region 11
The ring-shaped area 12 on the inner side of is formed of a red reflective sheet, and the display pattern 13 of "50" in the circular area on the inner side of the area 12 is formed of a blue reflective sheet. The area 14 excluding the display pattern 13 of "50" is formed of a white reflective sheet.

The color scheme and pattern of the speed regulation sign shown in FIG. 16 are "commands for road signs, marking lines and road markings" (1960, Prime Minister's Office, Ministry of Construction Ordinance, in consideration of visibility, etc.). No. 3, hereinafter referred to as the "Sign Order"). The lightning type variable speed regulation sign is also approved by the signing law, but it is only approved as a special case under the technical restriction that the background color is limited to black. Even in the case of the variable speed regulation sign, it is preferable that the background color of the display pattern is a color originally defined.

The circumstances described above are the same not only for variable speed regulation signs but also for other variable signs.

The present invention has been made in view of the above-mentioned circumstances, and has a long life without mechanically moving parts. Further, the background color of the display pattern can be prevented while preventing erroneous recognition. It is an object of the present invention to provide a variable label capable of increasing the degree of freedom of selection.

And the display pattern of the numeral "70" indicating that the regulated speed is 70 km / h are switched between the two display patterns to be displayed in blue, and the display pattern of the two display patterns is displayed. The background of one type of display pattern is displayed in white. FIG. 2 is a diagram showing a display state in which the display pattern of “50” of the variable speed regulation sign shown in FIG. 1 is displayed. Figure 3
FIG. 3 is a diagram showing a display state of a display pattern of “70” of the variable speed regulation sign shown in FIG. 1.

The variable speed regulation sign according to the present embodiment is
In the ring-shaped region 21 along the outer periphery, the ring-shaped region 22 inside this region 21, and the circular region inside this region 22, the display patterns of “50” and “70” are displayed. The display pattern display scheduled area (the whole of a large number of small circle areas 23 shown in black in FIG. 1) for displaying any one of them and the display pattern display scheduled area of the circular area inside the ring-shaped area 22 And an area 24 except for.

The area where the background of the display pattern of "50" is to be displayed is an area obtained by adding the area 24 and the area 23 of the small circle shown in white in FIG. 2, and the background of the display pattern of "70". The area where is to be displayed is an area obtained by adding the area 24 and the small circular area 23 shown in white in FIG. Therefore, the background display planned area in which the background of either the display pattern of “50” or the display pattern of “70” should be displayed is
The area 24 and the small circle area 23 shown in white in FIG. 2 and FIG.
This is a region to which a small circle region 23 shown in white is added. The fixed background area, which is an area excluding the display pattern display scheduled area, in the background display scheduled area is an area 24. The common area between the display pattern display scheduled area and the background display scheduled area is an area obtained by adding a small circle area 23 shown in white in FIG. 2 and a small circle area 23 shown in white in FIG. Is. Areas 21 and 22 are fixed display areas for fixedly displaying a predetermined color in addition to the display scheduled area and the background display scheduled area, respectively.

In the present embodiment, each region 23 is provided with a plurality of LED units 31 shown in FIG. 4 over almost the entire region 23. FIG. 4 is a schematic enlarged front view showing the LED unit 31, in other words, FIG.
It is shown by enlarging a part of one area 23 in the inside. The LED unit 31 is formed by arranging five blue LEDs 32 and four white LEDs 33 as shown in FIG. Note that the light emitting surfaces (light emitting regions) of the LEDs 32 and 33 appear in FIG.

Therefore, in the display pattern display scheduled area, a group of light emitting areas whose emission color is blue (in this embodiment, the light emitting surface of the blue LED 32) and a group of light emitting areas whose emission color is white ( In the present embodiment, the light emitting surface of the white LED 33) is mixed.

In the present embodiment, the fixed background area 2

In the present embodiment, the background color of the display pattern can be arbitrarily determined, unlike the conventional variable speed regulation sign of the electric type, and therefore the normal speed which is not the conventional variable speed shown in FIG. Similar to the regulatory sign, it is possible to realize the white background color originally specified in the signage.

Further, according to the present embodiment, since two types of display patterns can be switched and displayed as described above, there is no mechanically movable part and the life can be extended.

Further, according to the present embodiment, the blue LEDs 32 existing in the area 23 of all the small circles are turned off and the white LEDs 33 existing in the area 23 of all the small circles are turned off.
By turning on, all display patterns can be hidden, and thus it is possible to display that there is no special speed regulation and the speed is regulated to the legal speed.

Furthermore, according to the present embodiment, since the outside light is strong during the daylight hours, the LEDs 42 and 52 existing in the areas 21, 22 and 24 are turned off, and the areas 21, 22 and 22 are turned off.
24 colors are displayed only by the reflection sheets 43 and 53. As a result, it is possible to reduce operating costs due to power consumption associated with lighting the LEDs 42 and 52. On the other hand, during the sunset time, since the outside light is weak, the LEDs 42 and 52 existing in the areas 21, 22 and 24 are turned on to turn on the areas 21 and 22,
The color display of 2, 24 is not limited to L as well as the reflection sheets 43 and 53.
This is also performed by light emission display by the EDs 42 and 52. Thereby, it is possible to improve the attractiveness and the visibility even during the sunset time.

The above operation can be realized by controlling the LEDs 42 and 52 by a control unit (not shown) based on a signal from the illuminance detector or a signal from the timepiece.

The first embodiment described above may be modified as follows, for example.

First, instead of using the white LEDs 33, 42, 52, LEDs of different emission colors may be used in combination so as to display white as a mixed color.

Secondly, instead of forming the non-emissive display area with the reflection sheets 43 and 53, the non-emissive display area may be simply a colored area made of paint or the like.

Third, in the case where all display patterns are not hidden, the white LED 3 is provided in the small circle area 23 shown in black in FIG. 2 and FIG.
You may remove 3.

Fourth, LEDs are provided in the areas 21, 22, and 24.
The regions 21, 22 and 24 may be formed only by the reflection sheets 43 and 53 without mixing 42 and 52, or may be simply colored regions.

Fifth, the small circle area 23 shown in white in FIG. 3 may be removed, and this portion may also be used as the fixed background area 24. In this case, the variable speed regulation sign displays one type of “70” display pattern in blue and also displays the background of this display pattern in white and hides this display pattern. It becomes a variable speed regulation sign to switch.

Sixth, as a structure in which the LEDs 32, 33, 42, 43 are mixed, instead of disposing the LED units 31, 41, 51 which are unitized in advance, individual LEDs are not converted into one unit but one LED each. You may employ the structure arrange | positioned. That is, for example, even if a red reflection sheet is provided over the entire fixed display area 22, holes for mounting individual red LEDs are provided in the red reflection sheet, and the red LEDs are arranged at the positions of the holes. Good. In this case, one red reflective sheet is continuous, but in the present specification, even in such a case, the group of non-light emitting display areas and the group of light emitting areas are mixed. .
