Description

[Detailed Description of the Invention] [Industrial field of application] The present invention installs roads on the roadside in areas where road surface may be frozen, areas that may be exposed to strong winds, areas that require caution during heavy rain, etc. The present invention relates to an improvement of the automatic variable alarm device.

[Conventional technology]

As the automatic variable alarm device as described above, one in which a caption consisting of a reflective sheet is used for the entire character portion, or
There is a variable type in which a light emitting diode fixed to a part of a display character is used, the other character portion is of a reflective type, and a reflective type dial plate is vertically placed at the position of the light emitting diode.

[Problems to be solved by the invention]

Variable display devices that use solar cells or commercial power sources have come into wide use, but there is a limit to how they can be seen when only a reflective sheet is used, and when the night headlight is a passing beam or bends. In the case of a road that does not have sufficient reflection effect unless the vehicle reaches a short distance, fog,
It has been required to be a self-luminous lamp that is completely invisible when it snows. On the other hand, the one using a light emitting diode for some characters has a simple structure, but since it is a dot shape,
There is a problem that the warning content becomes unclear and that the characters displayed on the light emitting diode cannot be identified in the daytime. The present invention solves the above-mentioned problems of the prior art, and provides an automatic variable warning device with good visibility regardless of the weather environment by using a battery equipped with a solar cell or a commercial power source as a power source. To aim.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention is characterized in that a surface light emitter is used for a display portion of a fixed plate, and one side is made transparent and another side is made to be reflective and driven to make it variable. And

[Work]

In the present invention, a surface light emitter (EL) is used as a light source on the whole surface or a part thereof, and a semi-transmissive film or plate on which characters or the like are printed is coated on the surface light emitter (EL) to provide good visibility in daytime and nighttime. By driving the subtitles, variable display can be easily performed, and a sufficient effect can be exhibited as an alarm device using a solar cell or a commercial power source as a power source.

〔Example〕

An embodiment of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 is a side view in which a part of the automatic variable warning device of the present invention is cut away, FIG. 2 is a front view of the same, and FIG. 3 is an enlarged front view of a part of a display character portion using a surface light emitter. It is a figure and a side view. In these figures, 1 is a pillar, 2 is a housing attached to the pillar, and a solar cell 3 is provided above the housing.
Is attached, and the electric power obtained by the solar cell can be stored in the battery 13. A fixed display unit 5 is provided in the housing, and the fixed display unit 5 is composed of display characters 5a, a semi-transmissive film or plate 5b, a substrate 5c, a surface light emitter 6 and the like. A display screen 7 is provided via rollers 9 provided above and below so as to surround the fixed display portion 5, and one side surface of the subtitle sheet 7 is a transparent film portion 7 ′, and one side surface corresponds to the opposite side surface. A display character 8 made of a reflective sheet is attached to the display screen 7. The display character 5a and the display character 8 formed by the reflection sheet, which appear to be raised by the light emission of the surface light emitters 6, are
Both are made visible through the front windshield 4. Further, a plurality of light emitting diodes are arranged on the upper front surface of the housing 2, and a blinking lamp 12 that blinks at night is provided. Further, 14 is a control unit and 15 is a sensor, which issues a freeze alarm in this embodiment, and the sensor 15 is a temperature sensor. Further, 10 is a driving motor for replacing the transparent film portion 7'of the display screen 7 and the reflection type display character 8 and is operated by the roller 9 via the transmission belt 11. The displayed character 8 forms a desired character, for example, "running caution" or "curve caution". In the case of this embodiment, the sensor 15
For example, when the sensor detects a value set as the detected temperature, the value is input to the drive circuit provided in the control unit 14 to drive the motor 10, and when the display character 8 is displayed on the front surface, the display curtain is displayed. It turns to the transparent film 7 side so that the display characters 5a printed or affixed to the semi-transparent film or plate appear, and at night, the blinking transmission circuit in the control unit 14 operates to activate the surface light emitter 6 Flashes and lights up so that the displayed characters can be seen from a distance. Whether the blinking operation in this case is an operation only at night, an operation at daytime or nighttime, or an interlocking operation with the blinking lamp 12 can be freely set by an electric circuit.

[Effect of device]

In this way, in normal times, the display characters made of a reflective sheet, for example, "running caution" are displayed,
For example, when the outside temperature drops to the freezing temperature, the display character 5
"a", for example, "freezing caution" appears and the surface light-emitting body emits light and blinks at night, so that good visibility of the displayed characters 5a can be obtained. Moreover, there is an effect that it is possible to realize an automatic variable warning device which has a simple structure and can sufficiently achieve its purpose as a traffic safety facility.
