Description

[Detailed description of the invention] The present invention relates to a variable display board, which is particularly used as a variable display board for road traffic or general advertising, and whose display surface can be freely changed as necessary. This invention relates to a variable display board.

Conventionally, as variable signs for road traffic, there are rotary variable signs that change the display surface by rotating a movable plate completely by an electric motor, and internally illuminated variable signs that change the display surface by winding up subtitles on a rotating drum. Proposed.

However, with these conventional variable signs for road traffic, the former cannot convert auxiliary signs for specifying vehicle types and sections at the same time as the main sign, and the combinations of displayed symbols or letters are limited, and the latter Since a total reflection sheet cannot be used, it is necessary to have a built-in illumination or light source device, which not only complicates the structure but also increases power consumption.

The present invention solves the above-mentioned problem, and consists of a plurality of movable display boards, each of which is guided by a guide rail and can move up and down freely on the front side of a fixed display board, arranged in parallel planes in front and back positions. , display the display surface of the fixed display board with all the movable display boards stored below the fixed display board, and move all the movable display boards sequentially upward, that is, to the front of the fixed display board through the joints. The display surface of the movable display board can be displayed while connected to the top and bottom positions, and a balance weight is suspended from the opposite end of the drive belt that lifts the movable display board that should be located at the top and moves it up and down. This makes it possible to reduce the power consumption required to move the movable display board up and down, thereby contributing to power saving, and the variable display board can be used not only as a variable sign for road traffic, but also as a variable display board for general advertising. The purpose is to provide display boards.

EMBODIMENT OF THE INVENTION Below, referring to the drawings, an embodiment in which the present invention is applied to a variable sign for road traffic will be described.

In the drawings, reference numeral 1 denotes a housing whose front side is open, and a front frame 3 using a hinge 2 at the edge of the opening is attached to the front frame 3 so as to be openable and closable. A translucent front cover 5 covering almost the entire surface of the front frame 3 is fitted, and a frame 6.6' is fixed to both left and right ends of the inside of the front frame 3, and the frame 6.6' rotates together with the front frame 3. Configure it so that it can be done.

A fixed display board 7 for displaying this sign on this frame 6.6'
Fixed display boards 8 for displaying and auxiliary signs are fixed side by side in longitudinal and vertical positions so that their respective display surfaces can be viewed simultaneously from the front side through the front cover 5, and fixed display boards 8 on the front side of the fixed display board 7 They are guided by guide rails 9 and 9' to move up and down freely, and a fixed display board 7 is mounted on the display surface.
Movable display boards 10 and 11 depicting display patterns or characters different from those shown in FIG. A movable display board 12 depicting a display pattern or characters different from that of the fixed display board 8 is arranged in parallel planes.

In the present invention, the movable display boards 10 and 11 are arranged in pairs, that is, the movable display boards 10 and 11 are connected vertically, and the main sign is displayed on both display surfaces. The displayed pattern or characters are drawn so as to be substantially divided into two parts, upper and lower.

The movable display boards 10, 11.12 are normally fixed display boards 7,
8, and if desired, it can be lifted upward and moved to the front of the fixed display boards 7, 8.
The display screens of movable display boards 10, 11, and 12 are displayed by shielding the display faces of 8, and adjacent movable display boards 10 and 11, and 11 and 12 are connected to each other in the upper and lower positions, respectively. A joint 13 is provided on the periphery of the two, so that when one moves to a predetermined height, the other can be successively connected and lifted.

14.14' is a drive chain that lifts and moves the movable display boards 1G and 11.12 up and down, and one end is fastened to the upper edge of the movable display board 10, which should be located at the top, and the other end is fastened to the upper edge of the movable display board 10, which should be located at the top. It is suspended from the rear surface of the fixed display board 5 via sprockets 15.15' arranged above the frame 6.6', and a balance weight 16 is attached to the tip thereof.

The movable display board 10. 11. 12 and balance weight 16 are balanced back and forth around a rotating shaft 17 that fixes the sprocket 15° 15', and the movable display plates 10, 1
1.12 can be moved up and down with a small force.

The sprocket 15.15' is connected to an electric motor 20 via a coaxially fixed gear 18 and a gear 19 that meshes with the gear 18, and by rotating the electric motor 20, the sprocket 15.15' can be rotated to vertically move the drive chain 14.14' and the movable display board 10.11.12 suspended from the drive chain 14.14'.

21 and 22 are microswitches for detecting the vertical movement positions of the movable display boards 10, 11, and 12; When it engages with the piece 23, it closes and detects the upper position of the movable display plate 10, and the balance weight 16 of the other microswitch 22 rises, and its upper edge touches the operating piece 2 of the microswitch 22.
4, the movable display panel 10 is disposed so that it can be closed and the lower position of the movable display panel 10 can be detected.

25 is a control section, and 26 is a power supply section.

In the present invention, the fixed display boards 7 and 8 and the movable display board 10
, 11.12 The display design or characters that should be displayed on the main sign or auxiliary sign are depicted using a retroreflective sheet, fluorescent paint, etc. In particular, when using a retroreflective sheet, its visibility must be improved. can be significantly improved.

The movable display boards 10, 11, 12 may be configured to be always stored above the fixed display boards 7, 8 and moved downwards as desired, or when multiple main signs or auxiliary signs are displayed. A plurality of movable display boards in which the display design or characters are drawn on a single fixed display board, and the display design or characters are divided into a plurality of upper and lower parts to display other main signs or auxiliary signs on the front of the fixed display board. It is also possible to arrange them in parallel planes.

Since the present invention is configured as described above, it is possible to freely change the display surface by moving the plurality of movable display boards corresponding to one or more fixed display boards up and down, and also to change the display surface freely. It is possible to provide a variable display board with a simple structure that can reduce the power consumption required for vertical movement and contribute to power saving.

In addition, the variable display board according to the present invention can be operated with dry batteries, so it can be installed at any location regardless of whether or not it is connected to a commercial power source.It can be used not only as a variable sign for road traffic, but also as a variable display board for general advertising. It can also be used as a display board.
