Description

[Detailed Description of the Invention] The present invention relates to a variable sign board that selects and displays a necessary sign depending on the time of day or road congestion.

As shown in FIGS. 1 to 3, the conventional variable sign board has both ends of a display screen 5 equipped with a large number of signs 4 fixed to a pair of rollers 2 and 3 assembled above and below in a container body 1. Then, by rotating the pair of rollers 2 and 3 in the forward and reverse directions and winding the display curtain 5 around the rollers 2 and 3 or letting it out from the rollers 2 and 3, the display curtain 5 is given a feeding drive and is installed on one side of the body 1. A specific sign 2 is selected and displayed on a display window 1a, and a lighting device 6 is turned on at night, etc., and light is projected from behind a display curtain 5 so that the sign 2 receives the light and is displayed clearly. It was hot.

However, conventionally, the sign 4 is displayed using one side of the body 1, so when installing it on the road of the oncoming lane, one variable sign board must be placed on the road of each lane individually. When double-sided display is performed at the same location, a pair of variable sign boards are installed back to back, which makes them bulky, large, and heavy, requiring a strong support structure. The switching had to be done for each variable sign board. Subsequently, a variable sign board was developed in which display windows were opened on both sides of the vessel body, the display screen was arranged so that it could be turned back and forth across both display windows, and a lighting fixture that was shared by both display windows was built into the vessel body. (Reference example, Jikko No. 48-18458,
Utility Model No. 49-85983).

However, with the above configuration, when the variable sign board is installed outdoors at a high location, and one of the display windows receives sunlight, resulting in a so-called backlight condition,
The shadow of the sign on the display curtain that appears in the display window will be reflected on the display curtain in the other display window, and this will overlap the other sign and make it difficult to read. There is a risk that the displayed content may be different.

An object of the present invention is to improve the double-sided display type variable sign board, and to provide a variable sign board particularly suitable for installation at high places outdoors.

In other words, the present invention provides display windows on the front and rear sides of the variable sign board body, and arranges a single display screen with a traffic sign attached inside the body between both display windows so that it can be run in reverse. and in a variable sign board in which the display curtain is driven to display a selected sign in each display window, a variable sign board is provided in the body of the display screen that is directed toward one display window or the other display window. This is a variable sign board characterized in that lighting fixtures are arranged alternately in vertical rows, and a wavy light-shielding plate having reflective surfaces on both sides is installed across each row of lighting fixtures.

Embodiments of the present invention will be described below with reference to the drawings. Conventionally, the display window 1a is provided only on the front side of the container body 1 as shown in FIG. 2, but in the present invention, as shown in FIG.
Display windows 11 and 12 are provided on the rear surface 10b, respectively. A pair of rollers 13 and 14 are installed horizontally in parallel at the front and back of the lower part of the container body 10.
is connected to the motor shaft 15, and the rollers 13, 14 are connected to the motor shaft 15.
Both ends of the display window 16 are fixed respectively, and the display curtain 16 pulled out from both rollers 13 and 14 is folded back and passed over upper auxiliary rollers 17 and 18, and is arranged between both display windows 11 and 12. . Therefore, by rotating the motor shaft 15 counterclockwise, the rollers 13 and 14 rotate forward, and the display curtain 16 is fed out from the roller 13 and the display curtain 1 is placed on the roller 14.
6 is wound around the display curtain 16, the display curtain 16 travels upward along the display window 11, is reversed at the upper end, and travels downward along the display window 12.

Further, when the motor shaft 15 is rotated clockwise, the display curtain 16 is let out from the roller 14 and wrapped around the roller 13, and the display curtain 16 runs upward along the display window 12, contrary to the above, Display window 11
Driving down along the road, each sign has its own window 1
1 and 12. Also,
The movement of the display curtain 16 is detected by the micro switch 19, and when the display curtain 16 has traveled the required distance, the display curtain 16 is moved.
6 is stopped, and the switched specific markers 20 and 21 are displayed in each display window 11 and 12.

Note that since the amount of winding up and the amount of feeding out due to the rotation of the rollers 13 and 14 are different, it is necessary to give pretension to the display curtain 16.

Further, within the vessel body 10, lighting fixtures 22 and 23 are installed alternately in upper and lower rows with the light projection direction facing the display window 11 or the display window 12, and each of the lighting fixtures 22, 23
A wavy light-shielding plate 24 having reflective surfaces on both sides is attached across the row to isolate the lighting fixtures 22 and 23 and prevent light from leaking backwards.

When turned on at night, etc., the lighting fixture 22 projects light onto the display curtain 16 on the display window 11 side, the lighting fixture 23 projects light onto the display curtain 16 on the display window 12 side,
Each sign 20, 21 is clearly displayed when exposed to light.

In addition, since the light-shielding plate 24 has reflective surfaces on both sides, it is possible to focus the light from the lighting fixtures 22 and 23 reflected by the curved surfaces onto the display windows 11 and 12, respectively, so that the signs 20 and 21 can be seen at night. can be made easier to see.

As shown in FIG. 5, the display window 11 on the front surface 10a
A sign 20 displayed from the rear surface 10b and a display window 12 on the rear surface 10b.
A large number of signs 20 and 21 are arranged on the display curtain 16 with the signs 20 and 21 displayed as one set, respectively, and the signs 20 and 21 are oriented in different directions with respect to the longitudinal direction of the display curtain 16.

In the present invention, the rollers 13 and 14 are rotated to provide a feeding drive to the display screen 16, and each set of specific signs 20 and 21 is selected and displayed on the display windows 11 and 12, respectively. Display window 1 on the front side 10a
Sign 20 displayed from 1 and display window 1 on rear surface 10b
Since the directions of the signs 21 that are displayed from 2 to 2 are different from each other, when the display curtain 16 stops, the signs 20 and 21 are simultaneously displayed in the display window 11 and 12 in their normal postures, respectively.

As described above, according to the present invention, since the inside of the container with display windows opened on both sides is isolated, signs with the same or different contents can be displayed in each display window without being affected by back light such as sunlight. In addition, since a wavy shading plate with reflective surfaces on both sides was used to isolate the interior of the container, the back side of the display curtain was illuminated with direct light from the lighting equipment as well as reflected light from the curved surface of the wavy shading plate, making the sign clearly visible. can be displayed in
Furthermore, since the wavy light-shielding plate is installed across the rows of lighting fixtures, there is virtually no need for any space for isolation, which makes it possible to make the device thinner, which in turn has the effect of making it smaller and lighter.
