Description

TECHNICAL FIELD The present invention relates to a height variable speed regulation sign blinding device.

BACKGROUND ART Conventionally, a technique described in Patent Document 1 has been known as a high-altitude variable speed regulation sign blinding device.
This conventional high-altitude variable speed regulation sign blindfold device has a substantially rectangular plate shape with a grooved frame arranged in a U-shape, a hook on the back of the upper part, and a spring opening/closing arm on the lower part. and a back plate behind it, and by hooking the hook to the top of the display board of the target variable speed limit sign and pulling the spring opening/closing arm downward, the variable speed control sign can be adjusted. The blind board for the regulation sign was attached to the display board of the target variable-height speed regulation sign, and after installation, a display panel corresponding to the speed regulation was inserted.
That is, the variable-height speed regulation sign blinding device of Patent Document 1 has the disadvantage that conventionally, the variable-height speed regulation sign was simply covered with a bag to hide the speed display, so the speed regulation display was not displayed. It has been improved to display speed restrictions.

Utility model registration No. 3077329

However, since variable-height speed regulation signs are installed high above the ground, both the conventional method of covering them with a bag and the method of Patent Document 1 do not allow for the installation of a bag or a variable-height speed regulation sign concealing device. Another problem is that it requires laborious and dangerous work such as climbing up and down a ladder or leaning over at a high position.

The problem to be solved by the present invention is to make it possible to hide variable-height speed regulation signs with safe and simple work without having to go up or down ladders or lean over during construction work on expressways. Another object of the present invention is to provide a height-variable speed regulation sign blinding device that can display a safe speed regulation speed such as "50" as needed.

In order to solve the above-mentioned problem, a variable height speed regulation sign blinding device according to claim 1 is provided that covers the front surface of a variable height speed regulation sign via a mounting bracket on a height variable speed regulation sign mounting column. A blindfold member that can be opened and closed is attached and fixed, and a remote opening/closing operation means that operates the opening and closing of the blindfold member,
The blindfold member includes a blindfold sheet large enough to cover the front surface of the variable-height speed regulation sign, a winding storage cylinder housing a winding shaft capable of winding up the blindfold sheet upward and pulling it back downward, and an upper end. A pair of left and right guide bars are each fixed to both ends of the winding storage cylinder and the lower ends are connected by a horizontal bar.
A weight bar is provided at the lower edge of the blind sheet, and guide rings are provided at both ends of the weight bar that can move up and down along the guide bars, respectively.
The remote opening/closing operation means includes a flexible shaft whose upper end is connected to one end of the winding shaft , and a winding device which is connected to the lower end of the flexible shaft and is mounted and fixed at a lower position of the mounting support. This is a method that is characterized by

Further, the variable height speed regulation sign blinding device according to claim 2 is the variable height speed regulation sign blinding device according to claim 1, which includes:
The means is characterized in that the blind sheet is provided with a speed limit display such as 50 during construction, etc.

Further, the height variable speed regulation sign blinding device according to claim 3 is the height variable speed regulation sign blinding device according to claim 1 or 2,
The winding device is characterized in that it includes an accelerating gear device comprising a large gear connected to a winding handle and a small gear connected to a flexible shaft.

In the height-variable speed regulation sign blindfold device according to claim 1, as described above, the blindfold member includes a blindfold sheet having a width that covers the front surface of the height-variable speed regulation sign, and a blindfold sheet that is rolled upward. and a winding storage cylinder that accommodates a winding shaft that can be pulled back downward, and a pair of left and right guide bars whose upper ends are fixed to both ends of the winding storage cylinder and whose lower ends are connected by a horizontal bar,
A weight bar is provided at the lower edge of the blind sheet, and guide rings are provided at both ends of the weight bar that can move up and down along the guide bars, respectively.
The remote opening/closing operation means includes a flexible shaft whose upper end is connected to one end of the winding shaft , and a winding device which is connected to the lower end of the flexible shaft and is mounted and fixed at a lower position of the mounting support. The variable height speed regulation sign can be hidden by operating a hoisting device fixed at a low position and pulling down the blind sheet. Note that by providing a weight bar on the lower edge of the blindfold sheet, the blindfold sheet can be pulled down smoothly.
Therefore, during expressway construction, etc., it is possible to hide the variable-height speed regulation sign with a safe and simple operation without having to go up or down a ladder or lean out.

In the height-variable speed regulation sign blinding device according to claim 2, as described above, the blindfold sheet is provided with a speed regulation display such as "50", so that the height-variable speed regulation sign is simply hidden. In addition, it is possible to display the safe speed limit during construction work, etc.

Embodiments of the present invention will be described below based on the drawings.

First, the height-variable speed regulation sign blindfold device of Example 1 will be explained based on the drawings.

As shown in FIGS. 1 to 5, this height variable speed regulation sign blindfold device attaches the front surface of the height variable speed regulation sign 3 to the height variable speed regulation sign mounting column 1 via the mounting bracket 2. It is provided with a blindfold member 4 which is attached and fixed in a covering state and can be opened and closed freely, and a remote opening/closing operation means 5 which operates the opening and closing of the blindfold member 4.

More specifically, the blindfold member 4 includes a blindfold sheet 41 having a width that covers the front surface of the variable height speed regulation sign 3, and a winding shaft 42 capable of winding up the blindfold sheet 41 upward and pulling it back downward. The lower end of the blind sheet 41 is provided with a housing winding storage cylinder 43 and a pair of left and right guide bars 45, 45 whose upper ends are respectively fixed to both ends of the winding storage cylinder 43 and whose lower ends are connected by a horizontal bar 44. A weight bar 46 is provided at the edge, and guide rings 47, 47 are provided at both ends of the weight bar 46, which can move up and down along the guide bars 45, 45, respectively.
