Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a lower storage device for a wind and snow fence that can lower and automatically store a plurality of wind and snow board units in a nearly vertical state when not in use. It is related to.

[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.
