Description

本考案は道路用車線規制棒に関するものであって、更により詳細には車両の不法Uターン及び他側車線への進入を規制する規制棒に車両の接触による外力が加わると弾性変形され、その衝撃を吸収した後、原状復帰されて車両と規制棒が変形及び破損されないように考案されたものである。   The present invention relates to a road lane control rod, and more specifically, when the external force due to the contact of the vehicle is applied to the control rod that restricts the illegal U-turn of the vehicle and the approach to the other lane, it is elastically deformed. After absorbing the impact, the vehicle is restored to its original state, and the vehicle and the control rod are designed not to be deformed or damaged.

一般的に、道路には中央線侵犯及び不法Uターンは勿論、他側車線への進入を防止し、車線の案内のための道路安全用規制棒が設置されている。
このような道路安全用規制棒は通常的に金属材あるいは合成樹脂材で製作されて道路に固定されるように設置されている。
しかし、このような規制棒は、運行中にある車両が規制棒と接触することになると、上記規制棒が衝撃力によって変形及び破損されることは勿論、車両にも変形を発生させて車両を運行する運転者が物質的被害を直接被ることになる問題点があった。
一方、上記車両との接触によって破損された規制棒は道路辺に飛散されて、さらに他の大型交通事故を誘発させる問題点があった。
又、上記規制棒は道路の地面に接して固定される座台と、上記座台の上部に立てられる支柱が一体に形成されているので、上記座台や支柱が変形及び破損された場合、部分的な入れ替わりを行うことができず、不要な資源を無駄にするとの問題点があった。 Generally, road safety regulation rods are installed on roads to prevent lane traffic and illegal U-turns as well as to enter other lanes and to guide lanes.
Such a road safety regulating rod is usually made of a metal material or a synthetic resin material and is installed so as to be fixed to the road.
However, such a restriction rod is not only deformed and damaged by an impact force when the vehicle in operation comes into contact with the restriction rod, but also causes the vehicle to deform and There was a problem that the operating driver suffered material damage directly.
On the other hand, there is a problem in that the regulation rod damaged by the contact with the vehicle is scattered on the roadside and induces another large traffic accident.
In addition, since the restriction rod is integrally formed with a pedestal fixed in contact with the ground of the road and a support column that stands on the top of the pedestal, when the pedestal or support column is deformed and damaged, There was a problem that it was not possible to perform partial replacement, and unnecessary resources were wasted.

従って、従来にも上記のような問題点を解決するため、座台と支柱を分離し、上記支柱と座台をワイヤ又はスプリングで連結して復元するようにしている。
しかし、上記のように座台及び支柱がワイヤや板スプリングのような弾性部材によってのみ支持連結されることで、復元現象が繰り返し、時間が経つにつれて、その弾性部材の弾性復元力が低下され座台の一側に支柱が垂れ下がれる問題点があった。
本考案の目的は道路の地面にボルト締結される座台と上記座台の上部に立てられる支柱の連結強性を向上させると共に弾性復帰力が優れた道路用車線規制棒を提供することにある。
本考案の他の目的は座台と連結される支柱の強性を向上させて、上記支柱に一定の値以上の衝撃が加わる場合にも変形されるか又は破損されることが抑制されるようにする道路用車線規制棒を提供することにある。 Therefore, conventionally, in order to solve the above-described problems, the pedestal and the support are separated, and the support and the support are connected by a wire or a spring to be restored.
However, as described above, the pedestal and support are supported and connected only by an elastic member such as a wire or a leaf spring, so that the restoring phenomenon is repeated, and the elastic restoring force of the elastic member is lowered with time, and the seat is reduced. There was a problem that the column dropped on one side of the table.
SUMMARY OF THE INVENTION An object of the present invention is to provide a road lane control rod that improves the connection strength between a seat that is bolted to the ground of a road and a column that stands on the top of the seat and has an excellent elastic return force. .
Another object of the present invention is to improve the strength of the column connected to the seat so that the column is prevented from being deformed or damaged even when an impact of a certain value or more is applied to the column. It is to provide a road lane control rod.

このような本考案の目的は、道路にボルト(700)で締結される座台(200)と;上記座台(200)の上部に立てられる支柱(100)と;
上記支柱(100)と座台(200)を離脱防止するように連結する連結部材(600)と、上記支柱(100)が外部衝撃によって変形される時、再び立てられるように復帰させる弾性復帰手段(500)で構成されたものにおいて、上記連結部材(600)の上端部にはコイルスプリング形状である弾性復帰手段(500)の下端部が結合され、上記コイルスプリング形状の弾性復帰手段(500)の上端部が係合される係止板(410)が上部に形成された円筒形の支持パイプ(400)が支柱(100)の内部に設けられ、上記支柱(100)の下部には支持パイプ(400)が安着されるようにすると共に座台(200)に支柱(100)が立てられた状態で安着されるようにする受け台(300)が設置されることによって達成される。
従って、規制棒に車両の接触による外力が加わると支柱が弾性変形され、その衝撃を吸収した後、原状復帰されて車両と規制棒が変形及び破損されないようにすることである。 The purpose of the present invention is a seat (200) fastened to the road with bolts (700); a column (100) that stands on the top of the seat (200);
A connecting member (600) for connecting the support post (100) and the pedestal (200) so as to prevent detachment, and an elastic return means for returning the support post (100) to be stood up again when deformed by an external impact. (500), the lower end of the elastic return means (500) in the form of a coil spring is coupled to the upper end of the connecting member (600), and the elastic return means (500) in the shape of the coil spring. A cylindrical support pipe (400) having a locking plate (410) with which an upper end of the support is formed is formed in the upper part of the support (100), and a support pipe is provided below the support (100). This is achieved by installing a cradle (300) that allows the seat (200) to be seated and the seat (200) to be seated with the column (100) standing upright.
Therefore, when an external force due to vehicle contact is applied to the regulating rod, the support column is elastically deformed, and after the impact is absorbed, it is restored to its original state so that the vehicle and the regulating rod are not deformed or damaged.

このような本考案は、車両の不法Uターン及び他側車線への進入を規制する規制棒に車両の接触による外力が加わると弾性変形され、その衝撃を吸収した後、原状復帰されて車両と規制棒が変形及び破損されないようにする効果がある。
又、座台と連結される支柱の強性が向上されて、上記支柱に一定の値以上の衝撃が加わる場合にも、変形されるか又破損されることが抑制されるようにすることで、規制棒を設置及び維持及び補修の際、費用が低減されるようにする等の効果がある非常に有用な考案である。 This invention is elastically deformed when an external force due to vehicle contact is applied to the control rod that restricts the vehicle's illegal U-turn and entry into the other lane, absorbs the impact, and then returns to its original state. This has the effect of preventing the regulating rod from being deformed and broken.
In addition, the strength of the column connected to the seat is improved, and even when an impact of a certain value or more is applied to the column, it is suppressed from being deformed or damaged. It is a very useful device that has the effect of reducing the cost when installing, maintaining and repairing the control rod.

以下添付された図面によって本考案のその技術的構成を詳細に説明すれば次の通りである。
図1は本考案の設置状態を示した断面図であり、図2と図3は本考案の要部構成を拡大して断面図で示している。
上記座台(200)は図1及び図3に示しているように地面と結束のためのボルト(700)が通過するように結束孔(230)等が複数個穿孔され、中央には連結部材(600)が貫通するための通過孔(220)が穿孔される。
この座台(200)の上部に位置される支柱(100)は棒形状に夜間識別力を高めることができるように軸管体又は反射体等のような一つ以上の夜間識別具(110)が外側面に取付けられ、上記夜間識別具(110)が外側面に取付けられている支柱(100)の下部には受け台(300)が結合される。
上記受け台(300)は支柱(100)の下部外側面が内側壁面に接する下部蓋(310)と、上記支柱(100)の下部内側面に外側壁面が接する上部蓋(320)で構成されていて、上記下部蓋(310)に上部蓋(320)を安着させることによって、上記下部蓋(310)の内側壁面と上部蓋(320)と外側壁面との間に支柱(100)の下部が挿入されて固定して結合されるようにする空間部が形成されることで、上記受け台(300)に支柱(100)が固定されるように結合させることができる。
一方、支柱(100)に結合されている受け台(300)の下部蓋(310)底面部は膨らんで曲面部(311)が突出形成され、上記曲面部(311)と接する支持溝部(210)が座台(200)の上部面に形成されていて、座台(200)の上部に立てられた形態を維持する支柱(100)が外力が加わる場合、方向性なしで円滑に曲がり作用がなされることになる。 Hereinafter, the technical configuration of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a cross-sectional view showing the installation state of the present invention, and FIGS. 2 and 3 are enlarged cross-sectional views of the main configuration of the present invention.
As shown in FIGS. 1 and 3, the pedestal (200) has a plurality of bundling holes (230) drilled so that the ground and bundling bolts (700) can pass therethrough. A passage hole (220) through which (600) passes is drilled.
One or more night discriminators (110) such as a shaft tube or a reflector so that the column (100) located on the top of the seat (200) can increase the night discriminating power in a bar shape. Is attached to the outer surface, and a cradle (300) is coupled to the lower part of the column (100) where the night discriminator (110) is attached to the outer surface.
The cradle (300) includes a lower lid (310) in which the lower outer surface of the support column (100) is in contact with the inner wall surface, and an upper cover (320) in which the outer wall surface is in contact with the lower inner surface of the column (100). Thus, by lowering the upper lid (320) on the lower lid (310), the lower portion of the column (100) is placed between the inner wall surface of the lower lid (310) and the upper lid (320) and the outer wall surface. By forming the space portion to be inserted and fixed and coupled, the column (100) can be coupled to the cradle (300) so as to be fixed.
On the other hand, the bottom surface portion of the lower lid (310) of the cradle (300) coupled to the support column (100) swells to form a curved surface portion (311), and a support groove portion (210) in contact with the curved surface portion (311). Is formed on the upper surface of the pedestal (200), and when an external force is applied to the column (100) that maintains the standing state on the upper portion of the pedestal (200), it can bend smoothly without directionality. It will be.

勿論、上記受け台(300)下部に結合されている支柱(100)内部には上端部に係止板(410)が形成されている円筒形の支持パイプ(400)が設置される。
この際、上記支持パイプ(400)の外側面は支柱(100)の内側面に接触されて、上記支柱(100)を支持することで、支柱(100)に一定の値以上の衝撃が加わると、上記支柱(100)に加えられた衝撃エネルギを吸収及び分散させて変形が発生しないようにする。
又、座台(200)と受け台(300)が結合されている支柱(100)は連結部材(600)で連結することになる。
連結部材(600)は支柱(100)が車両衝突等によって曲がり変異が作用される際、曲がり変異が可能になり、支柱の離脱を防止するワイヤであることが明らかである。
この連結部材(600)の上端部には上端部が支持パイプ(400)の係止板(410)に結合されているコイルスプリング形態の弾性復帰手段(500)の下端部が結合され、上記弾性復帰手段(500)が結合されている連結部材(600)の下端部には座台(200)から連結部材(600)が離脱されることを防止するためワイヤよりその直径が大きい頭部(610)が形成されている。
従って、この連結部材(600)によって座台(200)及び支持パイプ(400)が内部に設置されている支柱(100)が分離されずに連結された状態を維持することができる。
一方、弾性復帰手段(500)はコイルスプリング形状で引張力及び原状復帰力が優れて成形されている。
このような本考案の車線規制棒は道路に車両が通過されないように規制する必要がある場所に設置することになるが、運転不注意等で衝撃が加わる場合、図1の仮象線で示したように支柱(100)の設置角度が変形されながらコイルスプリング形状の弾性復帰手段(500)がその変異を吸収した後、外力が除去されると、更に弾性復帰手段の引っ張る力によって再び復帰するようにすることである。 Of course, a cylindrical support pipe (400) having a locking plate (410) formed at the upper end portion is installed in the column (100) coupled to the lower part of the cradle (300).
At this time, the outer side surface of the support pipe (400) is in contact with the inner side surface of the support column (100), and by supporting the support column (100), an impact of a certain value or more is applied to the support column (100). The impact energy applied to the column (100) is absorbed and dispersed to prevent deformation.
Further, the support column (100) to which the seat (200) and the cradle (300) are coupled is connected by the connecting member (600).
It is apparent that the connecting member (600) is a wire that can be bent and deformed when the column (100) is bent due to a vehicle collision or the like and prevents the column from being detached.
The upper end portion of the connecting member (600) is coupled to the lower end portion of the elastic return means (500) in the form of a coil spring, the upper end portion of which is coupled to the locking plate (410) of the support pipe (400). In order to prevent the connecting member (600) from being detached from the seat (200) at the lower end of the connecting member (600) to which the return means (500) is coupled, a head (610) having a diameter larger than that of the wire. ) Is formed.
Therefore, the connecting member (600) can maintain the state in which the support (100) in which the seat (200) and the support pipe (400) are installed is connected without being separated.
On the other hand, the elastic return means (500) has a coil spring shape and is formed with excellent tensile force and original return force.
Such a lane control rod of the present invention will be installed in a place where it is necessary to control the vehicle so that it does not pass on the road. Thus, when the external force is removed after the coil spring-shaped elastic return means (500) absorbs the variation while the installation angle of the support column (100) is deformed, it is restored again by the pulling force of the elastic return means. Is to do.
