Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curb material for sidewalks arranged at an edge of a sidewalk at a boundary between a sidewalk having a step and a roadway, and a barrier-free sidewalk structure using the curb material for sidewalks.

[0002]

2. Description of the Related Art In recent years, the need to create a cityscape where people with disabilities can easily move has increased due to the barrier-free concept. For example, at the boundary between a sidewalk and a pedestrian crossing (roadway), a safer and more comfortable road can be created by improving the structure so that the sidewalk can be easily distinguished from the pedestrian crossing so that the pedestrian can easily enter the sidewalk. It is progressing. However, there is a conflict between safe and comfortable walkway structures for visually impaired and visually impaired people who use wheelchairs. For example, in a riding section from a pedestrian crossing (roadway) to a sidewalk, it is desirable for a wheelchair user to have difficulty in entering if there is a step, but if it is a slope, it is easy to enter. On the other hand, visually impaired people can reliably recognize the boundary between the pedestrian crossing and the sidewalk with the feeling of a cane or foot because of the step, but if it is a slope, it is not possible to distinguish the boundary between the two. Dangerous to.

Therefore, the barrier-free method stipulates that a step of 2 cm or less is provided in the riding portion from the pedestrian crossing (roadway) to the sidewalk so that all people can move safely and comfortably. Therefore, as shown in FIG. 5, a step with a height of 10 to 20 mm is provided by the curb material 3 at the boundary between the sidewalk and the pedestrian crossing (roadway) so that the sidewalk 1 and the pedestrian crossing 2 can be distinguished from each other. While wearing it, the visually impaired were able to recognize the boundary between the two with a cane. However, it is difficult for a wheelchair to get over even a step having a height of 10 to 20 mm, and the caregiver pushes the wheelchair carelessly at the boundary, so that the front wheel is caught in the step, and the impact causes the wheelchair user. There is a problem that may be shaken off in front.

On the other hand, as shown in FIG. 6, eliminating the step at the boundary between the curb material 3 of the sidewalk 1 and the pedestrian crossing 2 is convenient for wheelchair users because it enables smooth passage, but There is a problem for persons with disabilities that they cannot recognize the boundaries. In addition, a sloping surface that slopes from the sidewalk side to the pedestrian side is provided on the curb material at the boundary between the sidewalk with a step and the pedestrian crossing.
It is also possible to provide a level difference. This is convenient for wheelchair users because it enables smooth passage. However, there are only 5 steps between the crosswalk and the edge of the curb.
Since it is about mm, the step portion is immediately filled with sand or dust, and as a result, there is a problem that a visually impaired person cannot recognize the boundary between the two.
