Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a guide pavement for visually impaired persons who guides visually impaired persons such as blind persons and visually impaired persons.

[0002]

[Prior Art]

 Conventionally, visually impaired people have been guided by a linear marker for linear guidance and a dot-shaped marker for giving attention (hereinafter collectively referred to as Braille marker). People with impaired blindness detect this with a cane or foot, and those with low vision are guided by the contrast of the road markings with the yellow or other color of the braille marker.

Further, in recent years, for example, as described in Japanese Utility Model Laid-Open No. 61-14906, a magnetic marker is laid on the guideway, while a visually handicapped person is provided with a white cane incorporating a magnetic sensor and an electric control circuit. As a result, a magnetic induction method in which a magnetic sensor detects a magnetic substance and guides it by vibration transmitted to a white cane has been attempted. In addition, an antenna that captures the weak radio waves emitted from the magnetic sensor is embedded under the sign, and when a visually impaired person with the above-mentioned white cane comes in, a speaker is activated by the signal from the antenna to produce a voice. It is known that information is generated and safer guidance can be performed.

[0004]

[Problems to be solved by the device]

 As mentioned above, the braille marker system and the magnetic guidance system are both suitable for guiding visually impaired persons, but in this case, amblyopia, including people with cataracts, do not have a white cane. In some cases, the magnetic guidance system type might not function as a guiding pavement for the visually impaired. In addition, at night, it was difficult to see the color (yellow) of the Braille signs, and there was 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 guide pavement for visually impaired persons, who can surely guide even visually impaired persons, not to mention blind persons.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the present invention, a magnetic marker mixture layer containing ferrite as a main component is laid with a predetermined width in a walkway, and the magnetic marker mixture layer is provided along the mixture layer. The light emitting diodes are embedded and are connected to a control circuit for lighting each light emitting diode continuously or discontinuously.

[0007]

[Action]

 According to such a guide pavement for the visually impaired, a blind person with a white cane can be surely guided by the magnetic labeling mixture layer.

On the other hand, for a low vision person, the light emitted from the light emitting diode enables reliable visual recognition even at night, and enables walking along the light emitting diode.

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings of FIGS.

In the figure, reference numeral 1 indicates a guide pavement provided in a road 3. The guide pavement 1 is configured by continuously connecting magnetic marker bodies 5 having ridges 5a on the surface along the longitudinal direction. As shown in the cross-sectional view of FIG. 2, the magnetic marker 5 has 50% by weight of magnetite (Fe ₃ 0 ₄ ) powder having a particle size of φ0.6 mm or less in a non-magnetic cement concrete layer 7 formed in a predetermined block. And a magnetic marker mixture layer 9 having the ridges 5a is superposed on the upper surface of the ferrite cement mixture 9. Three light emitting diodes 11 are embedded in the magnetic marker mixture 9, and the upper surface of the magnetic marker mixture layer 9 is a surface coating layer 13 surface-treated with a synthetic resin material. Lighting of each light emitting diode 11 is controlled by the control circuit 14 as shown in FIG. The control circuit 13 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 marker mixture layer 9 varies depending on the amount of the soft magnetic material and the amount of mixture, and when a stainless sheet, an amorphous metal sheet or the like is used, the thickness of about 0.1 mm will still work. When the amount of ferrite mixed is small, the magnetism is improved by increasing the thickness up to about 30 mm, but the effect of the thickness is rapidly reduced when the amount is more than 30 mm. However, for the reason of molding, the magnetic marker mixture layer 9 and the cement concrete layer 7 may be molded integrally.

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, in order to bury it on the existing road surface, a groove for wiring or an existing pavement body is required. 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 embedded more easily by a method in which the cement concrete, the ferrite cement mixture, and the like are poured into the connected state. The adjacent electric wires 19 of the magnetic markers 5 of each block are connected by male and female connection terminals 21 when they are arranged in the longitudinal direction as shown in FIG. Further, the light emitting diode processing can 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 constructed as described above, even a blind person with a white cane having a built-in magnetic sensor can be surely guided by the magnetic marker mixture layer 9.

[0013] Next, for a visually impaired person who does not have a white cane, a light emitting diode that emits light enables easy visual recognition even in the case of amblyopia. it can.

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 combined with or without the light emitting diode 11. Further, the number of light emitting diodes 11 is not limited to three per block. Further, it is desirable that the color emitted by the light emitting diode 11 should be adapted to the region and environment. As a result, it is expected that not only the visually impaired but also the able-bodied will be able to walk and the benefits of deepening the understanding of people with disabilities can be expected.

[0015]

[Effect of the device]

 As described above, according to the present invention, a blind person with a blindness can correctly guide even a visually impaired person including an elderly person who suffers from cataract.

[0016] In addition, the lighting of the light emitting diode at night makes the streets a bright atmosphere, which is very preferable even for healthy people, and also has the advantage of being able to achieve an overall image change in a downtown area such as a shopping district. Be done.
