ようにした標識装置に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sign device such as a road sign plate for preventing snow from adhering to the front surface of the sign plate during snowfall.

Description of the Related Art A conventional road sign device, for example, a round road sign device incorporating a light-emitting diode and displaying the maximum speed by the light-emitting diode, when installed in an area with a large amount of snowfall, displays the sign by snowfall. Since letters and the like become invisible due to snow on the surface, a method of mechanically dropping or a method of utilizing a freezing point drop by a chemical substance is considered.

Therefore, a road sign device in which a heater is buried on the surface of the sign plate has been developed and used. However, since the power consumption is large, the electricity cost required for one season is considerable.

ａの前面に着雪するのを防止できると記載されている。In view of the above, there has been developed a device in which a snow-covered eave is mounted on the upper surface of a sign plate to prevent snow on the display surface. For example, Japanese Unexamined Utility Model Publication No. 4-44650 discloses this. That is, the inclined plate b is projected obliquely upward from the sign plate a, and a substantially vertical restraint plate c is extended forwardly above the inclined plate b at the protruding end of the inclined plate b.
In addition, it is described that the deterrent plate c prevents snow from accumulating on the inclined plate during snowfall and the deterrent plate c to serve as a snow eave to prevent snow from reaching the front surface of the sign plate a.

た問題があった。In the case of this snow protection plate, when snowfall occurs in the absence of wind, snow piles up on the inclined plate as described above, so that the snow on the display surface is small. However, if the wind is blowing toward the display surface, there is a problem that snow accumulates on the inclined plate but snow also occurs on the display surface.

いった問題があった。That is, as shown in FIG. 4, when wind blows from the surface of a sign board installed vertically, a wind stagnation point is formed at the center of the sign board and at the boundary between the inclined board and the sign board. From this point, since snow S develops, there is a problem that snow is formed at the center of the surface of the sign board and at the boundary, making it difficult to see the display.

The present invention is to provide a sign device provided with a snow accretion preventer characterized by preventing snow accretion on the display surface portion.

道路標識である。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a sign device provided with a snow accretion prevention device according to the present invention will be described below with reference to the drawings. 1
Is a control box for controlling a light emitting diode displayed on the front surface of the sign board 3, and a pole 2 is attached to the pole 1 through a mounting bracket 2a and a mounting member 2b.
It is fixed in a state inclined forward. The above configuration is a known road sign.

However, this snow-covered part is the signboard 3
Since it is out of the sign portion, there is no obstacle to recognizing the sign.

効ある効果を生じせしめることができる。According to the present invention, as described above, the sign plate is slightly inclined forward with respect to the vertical line, and the eave is formed on the upper edge of the sign plate with slight inclination. By creating a wind stagnation only in the upper part and forming a snowboard on this stagnation part, an eaves and a snowboard are added to the signboard that is tilted forward so as not to interfere with visibility. With a simple improvement, it is possible to produce an effective effect of preventing snow on the sign board surface.
