BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pavement for visually impaired persons who guide visually impaired persons such as blind persons and visually impaired persons.

[0002]

2. Description of the Related Art Conventionally, a visually impaired person is guided by a linear body for guiding in a straight line shape and a dot-shaped protruding body for giving attention (hereinafter collectively referred to as Braille marker body). There is. The visually impaired will detect this with a cane or foot, and the visually impaired will be guided by the contrast of the braille markings with the yellow or other color of the surrounding road surface material.

Further, in recent years, for example, the actual exploitation Sho 61-14.
As described in Japanese Patent Publication No. 906, while a magnetic marker is laid on the road, a white cane incorporating a magnetic sensor and an electric control circuit is provided to a visually handicapped person, and the magnetic sensor detects a magnetic substance and the vibration is transmitted to the white cane. A magnetic induction method of inducing is also attempted. In addition, an antenna that captures the weak radio waves emitted from the magnetic sensor is embedded in the lower part of the sign body, and when a visually impaired person with the white cane comes in, a speaker is activated by the signal from the antenna to make a voice. It is known that information is generated and safer guidance can be performed.

[0004]

As described above, both the Braille marker system and the magnetic guidance system properly guide the visually impaired. However, in this case, it can be applied to the visually impaired persons including those suffering from cataract. In that case, there is a case without a white cane, and there is a possibility that the magnetic guidance type may not function as a guidance pavement for the visually impaired. In addition, at night, it is difficult to see the color (yellow) of the Braille marker, and there is a particular lack of consideration for people with low vision.

Therefore, in this invention, it is an object of the present invention to provide a guiding pavement for visually impaired persons who can surely guide even visually impaired persons, not to mention blind persons.

[0006]

In order to achieve the above object, in the present invention, a magnetic labeling mixture layer containing ferrite as a main component, a plurality of ridges protruding from the surface of the mixture layer, A magnetic marker provided with a plurality of light emitting diodes embedded so as to emit light from the surface of the magnetic marker mixture layer at a position lower than the top of each ridge and a connecting terminal of the light emitting diode at the outer peripheral end has a predetermined size. It is formed into a block and is laid on the sidewalk so as to be in contact with each other along the longitudinal direction, and each magnetic marker and each light emitting diode of the magnetic marker are connected through the connection terminal. In addition, while forming a continuous magnetic labeling mixture layer, the connection circuit connecting each of the light emitting diodes and the light emitting diode is connected to a control circuit for making continuous lighting or discontinuous lighting.

[0007]

[Function] According to such a guide pavement for the visually impaired, for a blind person with a white cane having a built-in magnetic sensor,
The magnetic labeling mixture layer ensures that it is guided.
In addition, a person with a disability who has a cane that does not have a built-in magnetic sensor can be guided by a general Braille block by sensing the ridge at the tip of the cane.

On the other hand, an amblyopia without a cane can surely guide even at night by walking along the light emitted from the light emitting diode together with the sensing of the foot by the ridge.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described in detail below with reference to the drawings of FIGS.

Reference numeral 1 in the figure shows a guide pavement provided in a road 3. The guide pavement 1 is configured by continuously coupling the magnetic marker bodies 5 provided with the protrusions 5a protruding on the surface in the longitudinal direction. As shown in the cross-sectional view of FIG. 2, the magnetic marker 5 has a particle size φ0.6 mm on the non-magnetic cement concrete layer 7 formed in a predetermined block.
It is composed of a ferrite cement mixture in which 50% by weight of magnetite (Fe ₃ 0 ₄ ) powder described below is mixed, and has a structure in which a magnetic marker mixture layer 9 having the protrusions 5 a protruding from the surface is superposed. In the magnetic labeling mixture layer 9, three light emitting diodes 11 are embedded so as to emit light from the surface of the mixture layer 9 at a position lower than the top of the protrusion 5a protruding from the surface of the mixture layer 9. The surface of the magnetic marker mixture layer 9 is a surface coating layer 13 which is surface-treated with a synthetic resin material except for the region of the light emitting diode 11. Each light emitting diode 11 of each magnetic marker 5 is an electric wire 1
9, the connection terminal 21 is connected, and lighting is controlled by the control circuit 14 as shown in FIG. The control circuit 14 controls the energization time and the energization interval of the current from the power supply circuit 17 by receiving a signal from the external sensor 15 set based on environmental conditions such as a timer and an illuminance sensor. As a result, continuous lighting and blinking lighting can be obtained. The thickness of the magnetic labeling mixture layer 9 depends on the amount of the soft magnetic material and the mixed amount, and when a stainless sheet, an amorphous metal sheet or the like is adopted, the thickness may be about 0.1 mm. If the ferrite content is small, 3
If the thickness is increased to about 0 mm, the magnetism is improved, but if the thickness is further increased, the effect of the thickness is rapidly reduced. However, due to molding reasons, the magnetic marker mixture layer 9 and the cement concrete layer 7
And may be integrally molded.

On the other hand, since the light emitting diode 11 needs to have a constant thickness (about 30 mm) and the electric wire 19 needs to be arranged on the lower surface thereof, in order to embed it on the existing road surface, a groove for wiring or an existing pavement body is formed. Since stripping is required, it is preferable to wire and embed in a block in a factory beforehand. In this case, the light emitting diode 11 can be easily embedded by a method in which the cement concrete, the ferrite cement mixture, and the like are poured with the electric wire 19 being connected. The electric wires 19 of the magnetic marker bodies 5 of the adjacent blocks are the males provided on the outer peripheral ends of the magnetic marker tie bars 5 when they are aligned in the longitudinal direction as shown in FIG.
The connection circuit connected by the female connection terminal 21 and connecting the respective light emitting diodes 11 is connected to the control circuit 14 described above. The light emitting diode 11 can also be embedded in a braille marker made of ILB (interlocking block), pseudo stone block, or the like. Furthermore, in the case of drilling, it is possible to install it on conventional braille markers and molded products (non-magnetic).

According to the guide pavement thus constructed,
A person with a blindness who has a cane with a built-in magnetic sensor can be surely guided by the continuous magnetic labeling mixture layer 9. Also, for a disabled person who has a cane that does not have a built-in magnetic sensor, the guide can be performed by a general Braille block by sensing the protrusion 5a at the tip of the cane.

Next, for a visually impaired person who does not have a cane, in addition to sensing the foot by the ridge 5a, walking along the light emitted from the light emitting diode enables reliable guidance even at night. At the same time, the light emitting diode 11 is protected by the ridges 5a, and the influence of wear or the like is suppressed to a small level.

The guide pavement is not limited to a straight line, and may be arranged in a cross shape at the intersection as shown in FIG. 4, or may be a combination of those with and without the light emitting diode 11. Further, the number of light emitting diodes 11 is not limited to three per block. Furthermore, it is desirable that the color emitted by the light emitting diode 11 be adapted to the region and environment. As a result, not only low vision
It can be expected to bring the joy of walking to healthy people and to deepen the understanding of people with disabilities.

[0015]

As described above, according to the present invention, magnetic induction, light-emitting diode induction, and
In particular, it is possible to guide with a general Braille block without having a dedicated cane that senses magnetism, and it is possible for a blind person with impaired eyesight to certainly guide even a visually impaired person.

Further, the light emitting diode is protected by a ridge so that the influence of abrasion or the like can be suppressed to a small level, and the lighting of the light emitting diode at night makes the street a bright atmosphere, which is very preferable even for a healthy person. In downtown areas such as towns, there is the merit of being able to change the overall image.
