Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a wind and snow fence that can lower and automatically store a plurality of wind and snow board units in an almost vertical position when not in use. .

[Prior art]

Conventionally, it has been used as a downward storage type wind and snow fence installed on the side of motorways in snowy regions.
As disclosed in Publication No. 130623, the lower end of the upper frame having the upper support with an H-shaped cross section is foldably connected to the upper end of the lower frame having the lower support with an H-shaped cross section, and is extended laterally. A wind and snow board unit is constructed by fixing a horizontal rod to the widthwise middle part of a wind and snow board with a corrugated cross section. Connected via a link mechanism for plate expansion and stacking, the support member attached to the end of the horizontal rod of each wind and snow break plate unit is inserted into the side groove of the upper column, and then connected to the pulley attached to the upper end of the upper column. A wind and snow fence is known that has a structure in which the horizontal rods of the uppermost wind and snow board unit are supported by a lifting strip that is wrapped around the wind and snow board unit.

When storing each wind and snow board unit in this wind and snow fence below, each wind and snow board unit is lowered by the elevating strip, and the supporting member of each wind and snow board unit is inserted into the side groove of the lower support. At the same time, the wind and snow break plates are placed sideways and overlapped in close proximity.

[Problem that the invention seeks to solve]

However, in the case of the conventional wind and snow break fence, when each wind and snow break board unit is stored horizontally and downward, both ends of each wind and snow board unit are supported, so that the middle part of each wind and snow board unit is supported. As a result, moisture such as rainwater accumulates on the upper surface of the middle part of the wind and snow break board, making the wind and snow break easy to corrode, and foreign matter such as dust accumulates on the top surface of the wind and snow break board that is turned sideways. Furthermore, since a plurality of wind and snow break boards are placed sideways and stacked one on top of the other in the vertical direction, there is a problem that the appearance is not only bad but also dangerous for pedestrians.

[Purpose and structure of the invention]

〔Effect of the invention〕

According to this invention, when it is no longer necessary to use the wind and snow fence after the winter season, all the wind and snow board units 6 are simply lowered using the lifting strips 7, and each wind and snow board unit is lowered. Support member 1 in 6
0 descends through the guide space 9 between the support column 2 and the guide/holding member 8 and reaches the support member storage inclined member 13.
and then the inclined support member 1
3 toward the lower level side, and each support member 10 is overlapped in the longitudinal direction on the inclined support member 13, so that each wind and snow break between the left and right column support members 1 The board units 6 can be automatically stored so as to be stacked almost vertically, and furthermore, since the wind and snow break boards 4 in all the wind and snow board units 6 are stored in an almost vertically assembled state, they can be stored horizontally. Problems with the conventional downward storage type wind and snow fence are that moisture such as rainwater accumulates on the upper surface of the middle part of the wind and snow break board 4 that is bent due to the wind and snow break, and that foreign matter such as dust accumulates on the top surface of the wind and snow break board 4 that is oriented horizontally. In addition, the present invention has a good appearance and is highly safe for pedestrians.In particular, in the case of this invention, when each wind and snow board unit 6 is unfolded,
A support member 10 fixed to the end of the horizontal rod 5 of each wind and snow board unit 6 is disposed between the support column 2 and the guide/press member 8, and extends between the support column 2 and the guide/press member 8. Since the tightening bolts 11 are inserted, each support member 10 is tightened and fixed to the column 2 via the guide/holding member 8 using the tightening bolt 11, so that each wind and snow board unit 6 is secured. Effects such as being able to be fixed to the support column 2 in a stable state without shaking can be obtained.
