Description

Handrail for Pedestrian Protection {HANDRAIL FOR PERDETRAIN PROTECTION}

The present invention relates to handrails for pedestrian protection.

In general, at the boundary of a road through which vehicles pass and a sidewalk through which pedestrians pass, handrails for protecting pedestrians are installed to protect pedestrians from vehicles.

The handrail for pedestrian protection is coupled to the ground in a state of being erected with respect to the ground and includes a post having a hollow pipe shape and a crossbar disposed in the transverse direction to the posts.

The props of general pedestrian protection railings are mainly made of aluminum alloy, which is a lightweight metal, by extrusion method. Since light metal is used, if a vehicle collides with a pedestrian protection railing in the direction of the sidewalk, the pedestrian protection railing is easily damaged and protects pedestrians. It has a problem that it becomes difficult to protect.

On the other hand, if the pedestrian protection railing installed adjacent to the road is partially damaged or damaged by natural disasters, vehicle collisions, or pedestrians, it is difficult for road managers to obtain the manufacturer, contact information, and manager contact number of the pedestrian protection railing. There is also a problem that the maintenance and repair of the railing is difficult.

Of these, the crosspiece 400 may be made of a lightweight alloy metal or synthetic resin material, and the crosspiece 400 has a portion of the crosspiece 400 in the same shape as the post 100 shown in FIG. 1 to improve strength. It includes a cross-strength reinforcement portion (not shown) formed by twisting and at least one cross-strength reinforcement portion 410 extending to the inner surface of the crosspiece 400 .

As described above in detail, the railing for pedestrian protection improves the structure and improves the strength even though it is made of a lightweight metal material to improve the protection power of pedestrians, and in case of damage caused by natural disasters, vehicles or pedestrians, the road manager It is possible to quickly and easily obtain the manufacturer, manufacturing date, manager contact information, etc. quickly and easily, so it can be restored quickly.

On the other hand, the embodiments disclosed in the drawings are merely presented as specific examples to aid understanding, and are not intended to limit the scope of the present invention. It is apparent to those of ordinary skill in the art to which the present invention pertains that other modifications based on the technical spirit of the present invention can be implemented in addition to the embodiments disclosed herein.
