Abstract

PROBLEM TO BE SOLVED: To provide a windbreak fence which enables the drivers of vehicles to safely drive the vehicles by damping a cross-wind force by constituting a wall surface when a strong wind blows and to safely and comfortably drive the vehicles by securing a wide visual field without spoiling the spectacle under a relatively stable moderate atmospheric condition. SOLUTION: An upper panel 4 and a lower panel 6 are vertically connected to each other with hinges 5 between supports 1. To a fixed-side support 1A, an air cylinder 3 is installed with its cylinder rod 2 upside. Then the front end of the rod 2 is fixed to the internal top of a hollow moving-side support 1B which is slid upward/downward on the outer periphery of the support 1A. In addition, the bearing shaft 7 installed to the upper part of the side section of the upper panel 4 is pivotally attached to the support 1B and a bearing shaft 8 installed to the lower part of the side section of the lower panel 6 is pivotally attached to the support 1A.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a windbreak fence that is installed on a motorway or the like to attenuate a lateral wind force acting on a passing vehicle in a strong wind and to ensure a safe running of the vehicle. The present invention relates to a windbreak fence capable of securing a view under the condition.

[0002]

2. Description of the Related Art Conventional windbreak fences are panels which are vertically arranged in multiple stages between pillars, each of which rotates horizontally through an interlocking mechanism to be in a horizontally movable state, or a continuously movable type. A panel is provided between the installed columns, and a fixed panel and an open / close panel are alternately installed between the columns. One end of the open / close panel is rotatably fixed to one of the columns, and the other end is attached to and detached from the other column. There is an opening and closing type that locks as much as possible and pivots the opening and closing panel to overlap an adjacent fixed panel.

[0003]

A windbreak fence installed on a high-speed motorway or the like is an important protection facility for attenuating a lateral wind force acting on a passing vehicle at the time of a strong wind and ensuring safe running of the vehicle. The view is obstructed in summer or the like, in which relatively stable weather conditions continue, and it is particularly unsightly in a scenic area. Therefore, conventionally, as mentioned above, there are horizontal movable windbreak fences and openable and closed windbreak fences, but the horizontal movable windbreak fence has a thickness equivalent to the width of the front and rear of the panel even when the panel is in the horizontal state. Has a problem that it appears as a bar in the lateral direction.

[0004] Further, since the openable / closable windbreak fence is provided with the fixed panels and the open / close panels alternately provided between the columns, they are not continuously opened in the lateral direction. In addition, both the horizontally movable type and the openable / closable type windbreak fences do not have low supports, so that only the supports stand in forests and impair the surrounding scenery.

In view of the above, the present invention forms a wall surface in strong winds to attenuate the lateral wind to ensure the safe running of the vehicle, and in a relatively stable and calm weather condition, secures a wide field of view and impairs the landscape. It is an object of the present invention to provide a windbreak fence that enables a safe and comfortable running of a vehicle without any problem.

[0006]

In order to solve the above-mentioned problems, a windbreak fence according to the present invention is provided with two vertically arranged panels between extendable columns, and an upper panel and a lower panel are rotatably connected to each other. The upper part of the upper panel is rotatably fixed to the movable column, and the lower part of the lower panel is rotatably fixed to the fixed column. It is.

According to the present invention having the above structure, the column is extended in a strong wind to connect the upper panel and the lower panel in a vertical state, and has a function as a windbreak wall. By lowering the column on the moving side, both panels rotate about the connecting portion as a fulcrum and are folded downward, so that the upper part is opened and the visibility is wide and good.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a state in which the support of the windbreak fence of the present invention is extended, and FIGS. 2 and 3 shorten the support of the same,
This shows a state where the panel is folded.

In the drawing, reference numeral 1 denotes a hollow column having a rectangular cross section, which is erected at a predetermined interval. The column 1 has a double structure and is provided inside a column 1A on the inner fixed side. The air cylinder 3 is fixed with the cylinder rod 2 facing upward, and the tip of the cylinder rod 2 is positioned on the outer moving side support 1.
As the cylinder rod 2 is fixed to the top in B and the cylinder rod 2 expands and contracts, the moving-side column 1B moves up and down the outer periphery of the fixed-side column 1A.

An upper panel 4 using a perforated folded plate or the like between the columns 1 and 1, and a lower panel 6 whose upper part is rotatably connected to a lower part of the upper panel 4 by a hinge 5 are installed.
A support shaft 7 is provided above a side portion of the upper panel 4, and the support shaft 7 is rotatably mounted on a side portion of the support 1B on the moving side.

The support shaft 8 is also provided below the side of the lower panel 6.
Is provided, and the support shaft 8 is rotatably mounted on the side of the fixed-side support 1A. A notch 9 is formed upward from the lower end of the side surface of the moving-side support 1B, and the moving-side support 1B is formed.
In this case, the lower end of the column 1B on the moving side is not supported by the support shaft 8 of the lower panel 6.

[0012] The windbreak fence of the present invention having such a configuration is as follows.
In a strong wind, the cylinder rod 2 of the air cylinder 3 is extended, and the upper panel 4 and the lower panel 6 are kept vertical. If the cylinder rod 2 is shortened on a calm day, both panels are supported by the hinge 5 as a fulcrum. It pivots and folds down below the front of the panel. In addition, what is shown in FIG. 4 has panels provided on both sides of one support column 1, and this configuration has the same operation.

[0013]

According to the present invention, since the panel is folded downward by shortening the column, both the column and the panel are lowered, the visibility is wide and good, and only the column is not established. Without compromising the surrounding landscape. Therefore, the windbreak fence, which became a windbreak wall in strong winds and secured the vehicle's safe running from the side wind, can be safely and comfortably driven without compromising the scenery by folding the panel on a calm day if the panel is folded. Is what you do.
