When carrying out this invention, the connecting wire rope 34 may be omitted and the end of the lifting strip 9 may be directly connected to the supporting member 7 of the uppermost wind and snow fence unit 6. Further, any link mechanism other than that shown in the drawings may be used as the link mechanism that connects the plurality of wind and snow board units 6 so as to be expandable and foldable. Furthermore, as the stopper mechanism that allows rotation of the holding member 12 by approximately 90 degrees, any structure other than that shown in the drawings may be employed.

〔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, by simply lowering all the wind and snow board units 6 using the lifting strips 9, each wind and snow board unit can be lowered. Support member 7 in 6
is from the side groove 8 of the support column 2 to the storage groove 1 of the holding member 12.
0 and the lowest wind and snow board unit 6
The support member 7 is located at the stopper 1 at the lower end of the storage groove 10.
At the same time, the wind and snow break boards 4 in each wind and snow break board unit 6 are turned sideways and folded so as to overlap in the vertical direction, and then the holding member 12 holding each wind and snow break board unit 6 is folded.
By simply rotating the wind and snow breakers 4 by about 90 degrees, all the wind and snow breakers 4 in all the wind and snow breakers units 6 can be simultaneously changed from the horizontal orientation to the vertical orientation. Since the wind and snow break boards 4 in the board unit 6 are stored in a vertically assembled state, the wind and snow break boards 4 are bent in a horizontal state.
It is possible to solve the problems of the conventional downward storage type wind and snow fence, in which moisture such as rainwater accumulates on the upper surface of the middle part of the fence, and foreign matter such as dust accumulates on the upper surface of the horizontally oriented wind and snow break board 4. In addition, it not only looks good but also provides high safety for pedestrians.
