Description

DETAILED DESCRIPTION OF THE INVENTION The present invention can safely and accurately guide the walking of blind people, and at the same time prevent walking disorders of sighted people, thereby increasing the safety of both people while walking and significantly reducing the degree of fatigue during walking. To provide a method for guiding a blind person to walk, which can give an excellent feeling of walking.

As a conventional walking guidance method for blind people, a method is known in which guidance is provided by laying a pavement board 14 made of a concrete block integrally formed with hemispherical protrusions 13, as shown in Fig. 4A. Since the projections 13 of this pavement board 14 are made of concrete, it is hard and difficult for blind and sighted people to walk on, and the soles of their feet come into point contact with the projections 13, causing a great sense of fatigue. However, if it contains such materials, it has serious drawbacks such as being slippery when walking, and the installation of such materials to guide blind people has been a serious problem in terms of safety and walking performance. Furthermore, a non-slip pavement board 16 on which rubber pieces 15 are planted as shown in FIG. The degree of protrusion is extremely small, approximately 1.5 mm from the maximum surface, and using this for walking guidance for blind people is extremely difficult to distinguish due to changes in the tactile sensation of blind people, and there is a risk of confusion with products for other purposes. There was a problem that I could not use it because of the problem.

In view of these points, the present invention was created by creating a method for safely and accurately guiding blind people as a result of various experiments.The present invention is characterized by having a flat top surface that makes surface contact with the soles of the feet; A number of rod-shaped rubber paving slabs are integrally molded in parallel on the paving slab body so that the rod-shaped rubber pieces with the peripheral edge of the head formed into a convex surface with an arcuate cross section protrude by 3 mm from the surface of the paving slab body. A circular rubber piece is laid continuously in the longitudinal direction of the rubber strip, and the upper surface is flat so as to be in surface contact with the sole of the foot, and the peripheral edge of the head is formed into a convex surface with an arcuate cross section. A plurality of round rubber pavement slabs, which are integrally formed with a larger number than the rod-shaped rubber pieces arranged on the pavement slab body so as to protrude by 3 mm from the above, are combined with the continuously laid bar rubber pavement slabs. The purpose is to make it possible to guide blind people when walking by laying them consecutively at the position recognition part of destination points such as dangerous areas and crosswalk entrances.

To explain in more detail, the round rubber pavement board 1 used in the present invention has a flat top surface in contact with the sole of the foot as shown in FIG. 2, and a peripheral edge of the head 3 as shown in FIG. Diameter 19 formed on convex surface 4 with arcuate cross section
mm circular rubber pieces 5 are made to protrude by 3 mm from the surface of the pavement board main body 2, and the intervals between the rubber pieces 5 are arranged at equal intervals of 41 mm, 5 x 5 in length and width, for a total of 25 pieces, so as to improve the discriminating ability of the soles of the feet. It is arranged and integrally molded into the pavement board main body 2. The bar rubber pavement board 6 has a width of 17 mm and has a flat upper surface that makes surface contact with the sole of the foot as shown in Figure 1, and a peripheral edge of the head 8 formed into a convex surface 4 with an arcuate cross section as shown in Figure 1. A rod-shaped rubber piece 10... is made to protrude 3 mm from the surface of the pavement board body 7, and the rubber piece 10
The distance between the soles of the foot is 43 to increase the discrimination
Five of them are arranged in the longitudinal direction at equal intervals of mm and are integrally molded into the pavement board main body 7.

The two types of pavement boards 1 and 6 formed in this way are laid to guide blind people.In particular, the round rubber pavement board 1 is used to recognize the location of destination points such as stairway entrances and crosswalk entrances. The bar rubber pavement board 6 is effective on sidewalk surfaces such as straight walking, and an example of its use will be explained with reference to FIG. 3. Paving slabs 1... are installed in parallel, and the bar rubber paving slabs 6 are connected to the round rubber paving slabs 1, and the rubber pieces 1 of the bar rubber paving slabs 6 are connected to the round rubber paving slabs 1.
0 When the rubber pavement is laid continuously in the longitudinal direction, a blind person can identify the direction of travel by the bar-shaped rubber pieces 10 of the bar rubber pavement board 6. The circular rubber pieces 5 make it possible to go up and down the stairs while recognizing their position through the sense of touch, thereby safely and reliably guiding the person to walk.

Moreover, since the surfaces of the rubber pieces 6 and 10 on the pavement boards 1 and 6 are both formed into a flat plate shape, when walking, the sole of the foot and the surface are in surface contact, which significantly increases fatigue during walking. This reduces the amount of wear and tear and improves the walking feeling significantly. In addition, the peripheral edges of the heads 3 and 8 of the rubber pieces 5 and 10 are formed into convex surfaces 4 and 9 with an arcuate cross section, so despite the protrusion of 3 mm, they do not cause any hindrance when walking and are extremely superior. It gives a feeling of walking. The combination and arrangement of the bar rubber pavement board 6 and the round rubber pavement board 1 may be arbitrarily selected depending on the installation location. However, round rubber pavement slabs must be installed in the location recognition area to allow blind people to identify specific locations. Further, the number and arrangement of the rubber pieces are not limited to those in this embodiment, but the number of circular rubber pieces 5 is larger than that of the rod-shaped rubber pieces 10, and the rod-shaped rubber pieces 10 are parallel to each other. It is necessary that the

As described above, as a result of various experiments, the present invention has demonstrated that the walking of blind people, who need to be able to recognize and distinguish information through the tactile sense of a white cane or the soles of their feet, can be done safely and accurately by laying a combination of two types of pavement boards. This makes it possible to guide the user through the walking process, and furthermore, it can significantly enhance the feeling of walking.

In other words, by making the rubber piece protrude 3 mm from the tread surface, it is possible to identify and recognize the position of the sole of the foot or a white cane, and by making the surface of the rubber piece flat, it increases the ability to identify the sole of the foot and reduces fatigue when walking. This product was created in such a way that it significantly reduces the degree of discomfort and does not cause any hindrance to walking for long periods of time. In addition, the peripheral edge of the head of the rubber piece is formed into a convex surface with an arcuate cross section, thereby making the feeling of walking extremely good when walking.
