Description

【0001】
【発明の属する技術分野】
本発明は自動車道等に設置し、通行車両に作用する強風時の横風力を減衰し、車両の安全走行を確保するための防風柵に係り、比較的安定した気象状態下では視界を確保することができる防風柵に関するものである。
【0002】
【従来の技術】
従来の防風柵は、支柱間に上下方向に多段に設置したパネルが、連動機構を介して夫々が回動し、水平状態となる水平可動式のもの、或いは連続して立設した支柱間にパネルを設け、パネルは固定パネルと開閉パネルを交互に支柱間に設置し、開閉パネルの一端は一方の支柱へ回動可能に止着し、他端は他方の支柱へ着脱可能に係止し、開閉パネルを回動させて隣接の固定パネルに重合する開閉式のものは存在する。
【0003】
【発明が解決しようとする課題】
高速自動車道等に設置される防風柵は、通行車両に作用する強風時の横風力を減衰し、車両の安全走行を確保する重要な防護施設であるが、比較的安定した気象状態が続く夏季等においては視界が遮られ、特に風光明媚な地区では目障りな存在となる。
そこで、従来は上記のように、水平可動式防風柵や開閉式防風柵は存在するのであるが、水平可動式防風柵はパネルが水平状態となった時でもパネルの前後の巾分の厚さが横方向に棒状に現れる問題点を有している。
【0004】
又、開閉式防風柵は固定パネルと開閉パネルが交互に支柱間に設けられているので、横方向に連続して開放されることはない。
又、水平可動式や開閉式の両方の防風柵は、共に支柱は低くなることないので支柱のみが林立し、周囲の景観を損なうものである。
【0005】
上記点より本発明は、強風時に壁面を構成して横風力を減衰して車両の安全走行を確保し、比較的安定した穏やかな気象状態時には、視界を広く確保すると共に景観を損なうことなく、安全でかつ快適な車両の走行を可能とする防風柵を提供しようとするものである。
【0006】
【課題を解決するための手段】
上記課題を解決するため本発明防風柵は、伸縮可能な支柱間に上下二段にパネルが設けられ、上部パネルと下部パネルは回動可能に連結されると共に、上部パネルの側部の上方は移動側の支柱に回動可能に止着され、下部パネルの側部の下方は固定側の支柱に回動可能に止着されていることを特徴とするものである。
【0007】
上記構成を有する本発明は、強風時は支柱を伸長して上部パネルと下部パネルが垂直な状態で連結され、防風壁としての機能を有するが、比較的気象条件の穏やかな日は移動側の支柱を下降することより、両パネルは連結部を支点として回動し下方へ折り畳まれるため、上方が開放され視界が広く良好となる。
【0008】
【発明の実施の形態】
以下、本発明の一実施の形態を図面に基づき説明する。
図1は本発明防風柵の支柱を伸長した状態を示し、図2及び図3は同上の支柱を短縮し、パネルが折り畳まれた状態を示している。
【0009】
而して、図中1は所定の間隔を於いて立設した断面が四角形状の中空の支柱であり、この支柱1は二重に構成され、内側の固定側の支柱1A内にシリンダーロッド2を上向きにしてエアシリンダー3が固定され、シリンダーロッド2の先端が外側の移動側の支柱1B内の頂部に固定され、シリンダーロッド2が伸縮することにより、移動側の支柱1Bが固定側の支柱1Aの外周を昇降する。
【0010】
そして、支柱1、1間に有孔折板等を使用した上部パネル4と、上部パネル4の下部にヒンジ5で回動可能に上部を連結された下部パネル6が設置され、上部パネル4の側部の上方には支軸7が設けられると共に、支軸7は移動側の支柱1Bの側部に回動可能に軸着されている。
【0011】
又、下部パネル6の側部の下方にも支軸8が設けられ、支軸8は固定側の支柱1Aの側部に回動可能に軸着されている。
尚、移動側の支柱1Bの側面の下端より上方に向け切溝9が形成され、移動側の支柱1Bの下降時、移動側の支柱1Bの下端が下部パネル6の支軸8に支えないようになっている。
【0012】
このような構成を有する本発明防風柵は、強風時にはエアシリンダー3のシリンダーロッド2を伸長し、上部パネル4と下部パネル6を垂直な状態にしておき、穏やかな日にはシリンダーロッド2を短縮すれば、両パネルはヒンジ5部を支点として回動し、パネル前部の下方へ折り畳まれる。
尚、図4に示すものは、一本の支柱1の両側にパネルを設けたもので、かかる構成でも同様の作用を有する。
【0013】
【発明の効果】
本発明によれば、支柱を短縮することによりパネルが下方へ折り畳まれるので、支柱とパネルの両方が低くなり、視界が広く良好となると共に支柱のみが林立することがないので、周囲の景観を損なうことがない。
したがって、強風時に防風壁となり、横風から車両の安全走行を確保していた防風柵が、穏やかな日にはパネルを折り畳んでおけば景観を損なうことなく、安全かつ快適な車両の走行を可能とするものである。

BACKGROUND OF THE INVENTION
The present invention relates to a windbreak fence that is installed on a motorway or the like, attenuates a lateral wind force when a strong wind acts on a passing vehicle, and ensures a safe driving of the vehicle, and secures visibility under relatively stable weather conditions. It relates to a windbreak fence that can be.
[0002]
[Prior art]
In conventional windbreak fences, panels installed in multiple stages in the vertical direction between support columns rotate horizontally via an interlocking mechanism, and are horizontally movable, or between continuous support columns. A panel is provided, and a fixed panel and an open / close panel are alternately installed between the columns, and one end of the open / close panel is rotatably fixed to one column, and the other end is detachably locked to the other column. There is an open / close type that rotates the open / close panel to overlap with an adjacent fixed panel.
[0003]
[Problems to be solved by the invention]
Windbreak fences installed on expressways, etc. are important protective facilities for attenuating the lateral wind force in strong winds acting on passing vehicles and ensuring safe driving of the vehicle, but in the summer season when relatively stable weather conditions continue Etc., the field of view is obstructed, and it becomes annoying especially in scenic areas.
Therefore, as described above, there are horizontal movable windbreak fences and openable windbreak fences, but horizontal movable windbreak fences are thick enough for the width before and after the panel even when the panel is horizontal. Has a problem of appearing in a bar shape in the lateral direction.
[0004]
Further, since the openable windbreak fence is provided with fixed panels and openable panels alternately between the columns, the openable windbreak fence is not continuously opened in the lateral direction.
Moreover, both the horizontal movable type and the openable type windbreak fences are such that the support is not lowered, so that only the support stands and damages the surrounding landscape.
[0005]
From the above points, the present invention configures the wall surface during strong winds and attenuates the lateral wind force to ensure safe driving of the vehicle. An object of the present invention is to provide a windbreak fence that enables safe and comfortable vehicle travel.
[0006]
[Means for Solving the Problems]
In order to solve the above problems, the windbreak fence of the present invention is provided with panels in two upper and lower stages between extendable struts, the upper panel and the lower panel are rotatably connected, and the upper side of the upper panel It is characterized in that it is fixed to the movable column so that it can rotate, and the lower part of the side of the lower panel is fixed to the fixed column so that it can rotate.
[0007]
In the present invention having the above-described configuration, the struts are extended in a strong wind and the upper panel and the lower panel are connected in a vertical state, and have a function as a windbreak wall. By lowering the column, both panels rotate with the connecting portion as a fulcrum and are folded downward, so that the upper part is opened and the field of view is wide and good.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a state in which the column of the windbreak fence according to the present invention is extended, and FIGS. 2 and 3 show a state in which the column is folded and the panel is folded.
[0009]
Thus, reference numeral 1 in the figure denotes a hollow column having a square cross-section standing at a predetermined interval. This column 1 is double-structured, and the cylinder rod 2 is placed inside the column 1A on the inner fixed side. The air cylinder 3 is fixed with the tip facing upward, the tip of the cylinder rod 2 is fixed to the top of the outer moving column 1B, and the cylinder rod 2 expands and contracts so that the moving column 1B becomes the fixed column. Move up and down the outer periphery of 1A.
[0010]
Then, an upper panel 4 using a perforated folded plate or the like between the columns 1 and 1 and a lower panel 6 connected to the lower portion of the upper panel 4 so as to be rotatable by a hinge 5 are installed. A support shaft 7 is provided above the side portion, and the support shaft 7 is pivotally attached to a side portion of the movable column 1B.
[0011]
A support shaft 8 is also provided below the side of the lower panel 6, and the support shaft 8 is pivotally attached to the side of the fixed column 1A.
A kerf 9 is formed upward from the lower end of the side surface of the moving column 1B so that the lower end of the moving column 1B is not supported by the support shaft 8 of the lower panel 6 when the moving column 1B is lowered. It has become.
[0012]
The windbreak fence of the present invention having such a configuration extends the cylinder rod 2 of the air cylinder 3 in a strong wind, keeps the upper panel 4 and the lower panel 6 in a vertical state, and shortens the cylinder rod 2 on a calm day. If it does, both panels will rotate using the hinge 5 part as a fulcrum, and will be folded below the panel front part.
4 shows a structure in which panels are provided on both sides of one support column 1, and this structure has the same function.
[0013]
【The invention's effect】
According to the present invention, since the panel is folded downward by shortening the support column, both the support column and the panel are lowered, the visibility is wide and good, and only the support column does not stand up. There is no loss.
Therefore, the windbreak fence, which was a windbreak wall during strong winds and secured safe driving of the vehicle from crosswinds, can be used to fold the panel on a calm day, allowing safe and comfortable driving without compromising the scenery. To do.
