DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to laying for safely guiding and guiding visually impaired persons in station premises, platforms, toilets and exits, ascending and descending stairs, sidewalks and intersections, and in general buildings. It is about a board.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 3 (A), a laying board having uniform and regular projections as shown in FIG. The handicapped person can move left or right with the tip of the cane or proceed while checking the convexity by touching the feet.

[0003]

The above-mentioned conventional laying boards have various problems and are listed.

[0004] The guide band formed of a laying plate having uniform and regular projections is simply laid along a passage or a platform. A visually impaired person can only walk along a guide zone without knowing that he is walking off a passage or platform. However, it is not possible to know whether the vehicle is heading to the destination or retreating, which is the train side and which is the platform side. That is, the most basic guidance, that is, front, back, left, and right cannot be performed. A visually-impaired person can know at a glance which side of the taxiway the train enters. The visually impaired can be judged by the voices and footsteps of trains and people. The only person who has hearing loss in addition to visual impairment depends on memory and intuition.

[0005] Even if the user walks along the guidance zone, it is not possible to guide the user up or down the stairs ahead, toilets and exits on the right or left side, guidance on a forked road, intersections, etc., which is dangerous. There is also a guide band that changes from a long thin convex part to a round convex part, but it cannot be understood only from the feeling of the sole. A visually impaired person can know at a glance where and what they are. A visually impaired person can judge a person's voice and footsteps with difficulty. The only person who has hearing loss in addition to visual impairment depends on memory and intuition.

[0006] Guidance bands consisting of a laying plate having a convex portion formed on the surface are used only at stations and specific places. There are various reasons, but standing on top of it is a bit unstable and dangerous. In addition, when walking or running on it, the toe or heel may be caught or tilted sideways due to the step of the convex part. The convex portion also has an advantage as a guiding band for judging from the sole of the foot, but has a problem in safety a little. Even a visually-impaired person has a risk of falling over at the convex part of the guiding band. Visually impaired and hearing impaired people are more cautious than healthy people, so it is thought that there will be fewer accidents, but it is still unstable. It is for people with mobility impairments that the effects of the protrusions formed on the surface of the laying board are even more serious and dangerous.

In a general building, a laying plate having convex portions formed uniformly and regularly on its surface is hardly used. The biggest cause is that once it is laid, it is not possible to freely place objects on it, lay a jutan, or change the pattern.

[0008] The conventional visually impaired person holds a simple stick on a stick, supports weight, avoids obstacles in front, and confirms safety.
Walk along the guide band by hitting the convex part of the conventional laying board or swiping left and right. The floor is damaged because the walking surface is moved left and right with the walking stick. The walking is very slow because the protruding part is beaten with a cane or the protruding part is checked while being swept right and left. Arms and wrists get tired because the wand is always waving. You can know the position of the laying board, but you do not know what is ahead until you go and check it directly. Even if there are dangerous things such as stairs, escalators, intersections, etc., you cannot know in advance.
A person with normal vision can see at a glance if there is a dangerous place ahead. A visually impaired person can make a difficult but judgeable judgment based on human voices, footsteps, and car sounds. People with hearing impairment in addition to visual impairment have no choice but to rely on memory and intuition.

An object of the present invention is to provide a laying board for guiding a visually impaired person, which solves the above-mentioned problem of the conventional laying board.

[0010]

According to the present invention, a required number of magnets are provided inside a plate body formed of a magnetic flux transmitting body,
The present invention relates to a laying board for guiding a visually impaired person, which shows guidance information in a space near the surface in a pattern of lines of magnetic force due to the arrangement of magnets provided inside.

[0011]

According to the laying plate constructed as described above, the lines of magnetic force run in the space near the surface of the laying plate of the magnet 2 installed inside. Any material such as plastic, rubber, concrete, wood, aluminum and the like can be used as long as the material of the laying plate is a magnetic flux transmitting body. It can be selected according to the place to be used. As long as the magnet 2 emits magnetic lines of force, a permanent magnet,
Anything such as an electromagnet can be used. It should be selected according to the place to use and how to use it.

The arrangement of the required number of magnets 2 provided inside the plate body 1 is basically free, and there are countless patterns. By regularizing the use place and the pattern, the place can be easily determined. The guide pattern can be indicated by the arrangement pattern of the magnets 2. In a place where it is sufficient to simply walk along the guide band 10, the guide band 10 may be formed by a laying plate in which the magnets 2 are vertically and uniformly arranged regularly. The entrance of a train with danger, just before the up stairs, just before the down stairs, before the escalator, at the entrance of the elevator, just before the intersection,
Before the railroad crossing, etc., a laying plate on which the magnets 2 are arranged correspondingly is laid. Toilet, exit, telephone, direction, etc. can also be displayed by the arrangement of the magnets 2. The magnetic field line pattern can be varied depending on the arrangement of the north pole and the south pole. The arrangement pattern of the magnets 2 can be simple to complex. When an electromagnet is used, the magnetic force line pattern can be changed, such as the presence or absence of a magnetic force due to the turning on and off of the current, the strength of the magnetic force due to the strength of the current, and the reversal of the magnetic pole due to the reversal of the electrode.

Since the lines of magnetic force are not affected by the shape of the surface of the laying plate, they may be flat, convex, wavy, or any other type. As shown in FIG. 1B, the convex portions 11 are uniformly and regularly formed.
Magnet 2 even if it has the same shape as the
Can be set freely. FIG.
(A) If it is flat as shown in FIG. 3 (B), it is stable even if it stands on its top, its feet are not caught, and it is possible to lay a jutan.

The laying board of the present invention can detect the magnetic field lines with a stick having the magnetic field line receiver 5 built therein. When the magnetic field line receiving antenna 4 arranged at the tip of the stick main body 3 is within the range where the magnetic field lines reach, the built-in magnetic field line receiver 5 can receive the magnetic field lines in the space near the surface of the laying plate. The magnetic field line receiving antenna 4 is generally a coil as shown in the figure.
A weak current is generated when the coil passes through the magnetic field lines. However, in some cases, a reed switch (magnet switch) that responds to the magnetic field lines may be used. If there is no problem in hearing, the sound is converted into a sound signal, and the sound is output as a sound from the earphone 12 or the like as shown in FIG. If the hearing loss or the trouble of the earphone 12 are bothersome, they are converted into a vibration signal and output by vibration of the vibrator 13 or the like as shown in FIG. Instead of earphone 12,
You may use the vibration receiver for hearing-impaired persons using the vibration of a bone. As shown in FIG. 1 (E), the guide guide information can be known by walking or moving the cane with the tip of the cane near the surface of the laying board.

As a specific example, in the case of the laying board shown in FIGS. 1A and 1B, "pi-pi-pi-pi (voice)" or "bi-bi-bi (vibration)" is used. If you go to the right, you will get "beep ... beep (voice)" or "bib ... bib (vibration)". If you go left on the laying board of FIG.・ Pip-pip (voice) ”or“ bit-
······································································································ if
Bee bit (vibration) ". As an example of the guide band 10 using the laying board shown in FIG. 2A, when the laying boards are arranged in a vertical direction, when walking along the guide band 10, a “pip-pip-pip (voice)” or “ Bi-bi-bi (vibration), shake the stick to the right to “pi-pi-pi-pi (voice)” or “bi-bi-bit (vibration)”, or shake the cane to the left. "Beep ... Beep (voice)" or "Beep ..."
Bit-by-bit (vibration) ". If the guide zone 10 is provided on the platform 14 of the station, the train side and the walk side can be known as the guide information.

When proceeding along the guide band 10, it is possible to confirm the line of magnetic force of the magnet simply by walking with the tip of the stick close to the surface of the laying plate. The laying board and the cane do not need to touch, nor do they have to keep swinging the cane. It is possible to walk very smoothly and quickly as compared with the related art.
