The present invention relates to a pedestrian safety device, and more particularly, to a pedestrian safety device for preventing traffic accidents and falling accidents by being installed at both sides of a pedestrian crossing or a road and a subway stop line so as to block the entry of vehicles and pedestrians. .

In general, crosswalks are formed on the roads on which vehicles travel, so that pedestrians can safely pass the roads, and traffic lights are installed on both sides of these crosswalks to inform the pedestrians and vehicles when they pass. It is.

However, despite the traffic signal system described above, most vehicle drivers will drive the vehicle regardless of whether or not the pedestrian is passing, causing pedestrians to create psychological anxiety, especially when the vehicle violates the stop line. Traffic accidents in pedestrian crossings frequently occurred due to entering crosswalks or forcibly driving on congested roads.

In particular, although children who lack attention and judgment often pass, such as crosswalks in schools and housing complexes, no safeguards have been taken to ensure that children can cross the street safely.

However, a conventional technique for preventing traffic accidents in a crosswalk in advance is a strut installed vertically on a sidewalk, a motor installed inside the top of the strut, and a blocking rod which is coupled to the motor by a gear and operated at a 90 ° angle. The "pedestrian safety device" consisting of a support bar and a blocking rod coupled to the blocking rod support has been conceived as Korean Utility Model Registration No. 0255636, but the pedestrian safety device is structured to be operated by lifting the blocking bar at an angle of 90 °, Since a significant physical load is concentrated on the gears, the gears are easily broken, and the blocking rods have a considerable length, so that a collision with the surrounding objects occurs as the lifting rod is lifted. To have a lung. Also, in order to lift the blocking rod with a considerable load, the motor must be operated excessively and it may cause the equipment deterioration and failure due to the overload of the motor.

Moreover, the conventional blocking rods should be manufactured so that the length of the blocking rods corresponds to the length of the crosswalk. This means that the longer the length of the blocking rods, the greater the bending stress caused by the increase in bending stress, and in severe cases, the safety rods are cut off. As a result, the blocking rods fall on the road, causing traffic accidents due to collision with the vehicle. Also, since maintenance work is performed on dangerous roads, safety accidents are frequently caused by workers. It has a fatal drawback that can only be extremely limited.

Therefore, pedestrian safety devices that are installed on both sides of pedestrian crossings and roadways and subway stop lines or parking lots to efficiently block and pass pedestrians and vehicles are more urgently needed.

Accordingly, the present invention has been made to solve the problems of the conventional pedestrian safety device as described above, the winding device and the guide device installed on both sides of the crosswalk or roadway and subway stop line, and the winding device and the guide device By forming a blocking member that blocks the entry of vehicles and pedestrians while connecting and descending, the pedestrians can pass safely and prevent the accident of falling on the subway tracks. It is to provide a pedestrian safety device that prevents traffic violations in a vehicle's stop line violation, subway crash and crosswalk by inducing compliance with the stop line.
