Description

Improved Structure of Safety Guide Bar [0002]

More particularly, the present invention relates to an attachable sight line guiding rod, which can be installed without perforating a concrete or asphalt road surface, so that it can be installed without breakage of the road, and can be removed and replaced when the guide rod is broken, The present invention relates to a line-guiding rod which is easy to maintain.

Generally, the sight line stick is used for separating the center line like a median separator or preventing intrusion of a lane, and a reflector is provided so that it can be visually checked at night.

However, since the general visual indicator rod is integrally formed, it is necessary to replace the entire body of the vehicle from the road even if only a part of the vehicle collides with the vehicle, so that the replacement cost is increased. In addition, It is necessary to separate the guide bar from the position where the line-of-sight guiding rod is attached, and therefore, when the guide bar is replaced, the guide line is slightly displaced from the position where the guide bar is previously engaged. Therefore, there is a problem that it is difficult to newly attach the sight-guiding rod on the road surface.

Conventionally, in order to solve such a problem, Korean Patent Registration No. 10-1149719 has proposed a hollow tube-shaped protrusion formed with a groove along the longitudinal direction on the inner circumferential surface thereof and a protrusion on the road surface of the road to restrict the moving direction of the vehicle, A pedestal including a floor panel connected thereto; A fixing member inserted into the protrusion and protruding from the outer circumferential surface of the fixing protrusion in a shape corresponding to the groove of the protrusion and having a nut formed on the inner circumferential surface thereof; A connecting member including the nut, a bolt fastened to the bottom panel of the pedestal, and a coupling hole formed on the top of the bolt; A rubber material packing formed in a hollow tube shape so that the bolt of the connecting member passes through the center shaft and a coupling member which is inserted between the coupling member of the connecting member and the fixing member, And a body on which a reflector is formed on an outer circumferential surface of the body, wherein the body is provided with an elastic guide hole formed in the body in a longitudinal direction thereof.

However, the above-mentioned registered patent has a problem that the road is broken or damaged because the road surface of the road is punctured and fixed by a column or anchor.

 In order to solve such a problem of road breakage, the adhesive sight induction rod of Patent No. 10-1568661 filed and filed by the applicant of the present invention is installed by using an adhesive function by road surface and adhesive in order to prevent road breakage, , The induction rod and the supporting part are formed as a separate type to facilitate maintenance and repair.

However, the patent applied and registered by the present applicant has a problem that the adhesive function between the bottom of the supporting part and the road is weakened over time and the supporting part and the road drawing are separated during application in the field, Or when a departure occurs, there is a problem in that the administrator can not perform confirmation or maintenance quickly.
