Description

  The present invention is installed along the road and changes the flow of wind and snow to prevent the vehicle driver from impeding visibility due to wind and snow, or to deflect the direction of the wind flowing from the windward toward the road to the road surface. It relates to a snow fence that blows away the snow accumulated on the road surface.

In the winter snow-covered region, pillars are erected along the road at a predetermined interval, and snow fences with wing-type snow plates attached laterally are installed between the pillars.
This type of snow fence has a slope so that the wind blowing side of the wind path deflector plate that changes the wind direction is raised, and it is installed in the horizontal direction to deflect the wind passing through the fence into a slanting downward flow. There is an effect that the driving field of view can be secured by blowing off the snow accumulated in the vehicle or by deflecting the flow of the snowstorm below the eye level of the vehicle driver.
Japanese Patent Application Laid-Open No. 10-338909 and Japanese Patent Application Laid-Open No. 2002-227136 disclose techniques related to the airfoil deflector for the purpose of improving the effect of deflecting the wind direction (wind path) downward.

For example, as shown in FIG. 11, the conventional airfoil deflecting plate has a panel member 111 such as a steel plate attached to a wing frame member 113 with rivets 113g and screws. A gap s is generated between the material and the panel, and it is difficult to maintain the optimal shape of the panel.
Japanese Patent Application Laid-Open No. 2002-227136 discloses a cross-sectional hollow blade made of FRP. However, in FRP, there are many man-hours for forming a hollow cross section, and workability is not good.

The front panel is inserted into the upper panel insertion part of the front and rear edge members and fixed to the upper surface side of the front edge member, the intermediate member, and the rear edge member. It is inserted into the lower panel insertion part of the edge member, and fixed to the lower surface side of the front edge member, the intermediate member and the rear edge member. Plates and, characterized in that on a support in the struts at an interval in the vertical direction.

Here, the upper panel material refers to a plate material that forms the upper side surface of the wing, and the lower panel material refers to a plate material that forms the lower side surface of the wing.
The leading edge member refers to the frame member on the air blowing side of the wing-type air passage deflecting plate, and the trailing edge member refers to the frame member on the road side of the wing-shaped air passage deflecting plate.
Since the upper and lower panel members have upper and lower panel insertion portions on the upper and lower sides of the front edge member and the rear edge member, respectively, the front side of the upper panel material and the lower panel material. Insert the end and rear end into the upper and lower panel insertion parts of the front edge member and the rear edge member, respectively, and connect the upper panel material and the lower panel material to the intermediate member located between the front edge member and the rear edge member. Can be formed into an airfoil shape.

  After inserting the front and rear edge parts of the upper and lower panel materials into the upper and lower panel insertion parts of the front and rear edge members, fix them with rivets or screws.

By inserting the front end and rear end of the panel material diagonally into the insertion portion and bending the panel material, the panel inner receiving portion is placed at the end of the panel material. Since the abutting from the inner side and the locking side part are locked from the outer side to hold the panel material end, the assemblability and shape stability of the airfoil deflector plate can be further improved. Since the opening width of the insertion portion is larger than the thickness of the panel material, it is easy to insert the panel material into the insertion portion.
In addition, when a plurality of air path deflecting plates are supported in the vertical direction using support columns that are erected at predetermined intervals, the leading edge members or the trailing edge members of the air path deflecting plates are connected by a connecting member. Then, the rotation of the air path deflecting plate due to the wind pressure can be suppressed, and the plurality of air path deflecting plates are connected to each other, so that the air path deflecting plate can be prevented from being dropped or damaged. Furthermore, by connecting the uppermost or lowermost airway deflector plate to the cross member spanned between the columns with a connecting member, a so-called truss structure is obtained, and the entire twist, rotation and dropout are reliably prevented. Can do.
When the intermediate member is arranged between the upper and lower panel materials and serves as a member to maintain the shape of the wing and as a mounting member to the column, and provided with attachments to the column at both ends, The number of parts of the airfoil deflecting plate is reduced, and the assembly is further facilitated. At the same time, the airfoil deflecting plate can be easily mounted between the columns, and the strength of the airfoil deflecting plate can be secured by the intermediate member .
