Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide plate such as a Braille guide plate and the like, which enables a physically handicapped person, particularly a visually impaired person such as a blind person to grasp the meaning by tracing with his / her fingers. The present invention relates to a manufacturing method.

[0002]

2. Description of the Related Art Today, social development for people with physical disabilities is gradually progressing, but it is said that such development is limited to public facilities in large cities and is still insufficient in local cities and public facilities. I have no choice. This situation also applies to Braille guide plates used by visually impaired people.
The reality is that they are installed only in very limited places. One of the reasons for this is the Braille guide plate or the manufacturing method thereof that has been conventionally used. That is, as shown in FIG. 15, the conventional Braille guide plate has a metal plate 100 made of iron or stainless steel.
A plurality of convex portions 101 corresponding to one braille character from the back surface of the
Plural types of pressing blocks 10 in which a is formed on the front surface
1 is pressed in order by the arrow A method at a predetermined pressure, one by one, to press on the metal plate 100, and thereby the convex portion formed on the pressing block 101 on the front surface of the metal plate 100. Convex portion 1 corresponding to 101a
00a are sequentially formed to display specific meaning contents as a whole.

[0003]

However, the Braille guide plate according to the above-mentioned conventional manufacturing method is manufactured by pressing the pressing block 101 on the metal plate 100 as described above. There are various problems to be solved. That is, since it is due to pressing, the metal plate 100 is often distorted, and as a result, the Braille guide plate cannot be reliably fixed to the wall surface of the structure or the like, and therefore such distortion is not generated after the pressing process. A correction process is required. Further, in order to have a specific meaning content as a whole, the individual pressing blocks 101
Since they are sequentially pressed one by one, not only does it take a long time to manufacture, but also the pressing lengths of the convex portions 100a forming the individual Braille characters are different because the pressing forces vary. In many cases, there are variations.
Furthermore, if a typographical error or a typographical error is confirmed during or after manufacturing, the metal plate 100 cannot be used anymore, and it is necessary to start the manufacturing from the first step, and similarly the predetermined Even if the display contents such as the telephone number and the address are changed after installation in the place and other parts do not need to be changed, the original Braille guide plate cannot be modified, and a completely new Braille guide plate cannot be modified. Braille guide plates must be manufactured. Regarding the size of each braille, in the conventional manufacturing method described above, it is necessary to prepare various kinds of pressing blocks 101 according to the size even if the braille is the same, and the braille can be small. As the distance increases, the convex portions 100a forming the individual Braille characters may interfere with each other, and the user may not be able to reliably grasp the meaning of the Braille guide plate.

On the other hand, at present, not only congenital visually impaired persons but also acquired visually impaired persons due to causes such as traffic accidents are increasing year by year. You cannot use the Braille guide plate unless you master Braille.

Therefore, the present invention was proposed in order to effectively solve various problems of the above-mentioned conventional Braille guide plate and its manufacturing method, and can be manufactured in a short time without distortion. It is an object of the present invention to provide a guide plate which can be reused by correction and can be made clear even with small Braille, and a manufacturing method thereof. Further, in addition to the above objects, the present invention also aims to provide a guide plate that can be used by persons with acquired visual impairment who do not master Braille, and a method for manufacturing the guide plate. The purpose is to improve welfare by popularizing information boards.

[0006]

The present invention has been proposed in order to achieve the above-mentioned object, and its first
Relates to a guide plate, a flat plate, a plurality of convex member placement portions formed on the flat plate and corresponding to Braille, numbers or letters, and a lower end of the convex member placement portion and a top end of the convex member placement portion. A plurality of convex members that are fixed so as to project from the surface of the flat plate.
The guide plate may be one in which the convex member and the flat plate are fixed by a sheet member attached to the flat plate. A second aspect of the present invention relates to a method for manufacturing a guide plate, which includes a step of forming a plurality of convex member mounting portions corresponding to Braille, numbers, or characters on a flat plate, and a step of mounting these convex members. It is characterized by comprising a step of disposing a plurality of convex members on the placing portion and a step of fixing the flat plate and the convex member. The step of fixing the flat plate and the convex member constituting the manufacturing method may be a step of sticking the sheet body on the flat plate in which the convex member is provided in the concave portion or the through hole. The flat plate that constitutes the first invention and the second invention may be resin, hard rubber, wood, or glass in addition to metal materials such as iron, copper, and aluminum. In addition, the convex member mounting portion is, for example, a through hole,
As long as at least a convex member is provided, such as a through hole, a concave portion or a groove portion, and a slit, these forming methods are not limited to the case where a laser beam is used. A turret punch or the like may be used in the case of posting, or etching may be performed in the case of using a metal material as the flat plate. Further, when forming a concave portion as the convex member mounting portion, a trimming device may be used. The convex member constituting the present invention is, for example, a sphere, a pin, an object having a shape such as a rivet having a spherical surface formed at one end, an object having an oval shape, an object having a shape like a bullet, and the like. The wire may be a wire such as a wire as long as it is mounted in at least the convex member mounting portion so that the upper end thereof projects above the flat plate.

[0007]

According to the guide plate of the above invention, the convex member mounting portion to which the convex member is fixed is, for example, a through hole, a concave portion or a groove portion, and a slit, and the convex member is disposed and fixed on the convex member mounting portion. However, since the convex portion is not formed by pressing, there is no risk of distortion of the flat plate, and therefore the step of correcting the distortion is unnecessary, and a prompt and inexpensive guide plate can be manufactured. it can. Further, for example, when the guide plate according to the present invention is a Braille guide plate, by making the shape of the convex member mounting portion and the convex member small, clear Braille without mutual interference between the convex members. Can be formed. In addition, by forming a convex member mounting portion corresponding to characters such as katakana, numbers or alphabets, and fixing the convex member as described above, even a visually impaired person who does not master Braille can obtain it. Can be used. Further, the present invention is configured such that the predetermined meaning content as Braille, numbers, or characters can be grasped by a plurality of convex members mounted and fixed on the convex member mounting portion, Since the convex portion is formed by the pressing process and the predetermined meaning is not grasped as a whole, the convex portion can be formed uniformly without variation. In addition, even if a typographical error is found during manufacturing, or if it is necessary to change the contents of the guide plate once manufactured, a predetermined material is embedded in the convex member mounting portion and the convex portion is projected again at the same position. Since it is sufficient to form the member mounting portion, it is not necessary to discard the flat plate and it can be reused.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the guide plate and the manufacturing method thereof according to the present invention will be described in detail below with reference to the drawings. First,
A method of manufacturing the guide plate according to the first embodiment will be sequentially described according to each step. First of all, as shown in FIG.
The through hole 3 as the convex member mounting portion constituting the present invention is formed. The material of the flat plate 1 may be not only a metal material such as iron, aluminum and copper, but also a thermoplastic resin such as vinyl chloride resin, ABS resin, methacrylic resin and polyamide, or wood. The laser light 2 is emitted from a conventionally known laser device such as a C0 ₂ laser _or YAG.
(Yittrium-Aluminium-Garne
t) Laser or excimer laser, etc., and preferably a numerically controlled laser device is used. In addition, the through holes 3 formed by the laser light 2 correspond to the respective points forming the Braille which has been popularized in the present embodiment, and the through holes 3 as a whole are specified. It is formed at a position that has the meaning and meaning of. Then, the flat plate 1 is formed by the laser light 2 described above.
After the plurality of through-holes 3 are formed in each of the through-holes 3, a spherical body 4 as a convex member constituting the present invention is placed in each of the through-holes 3 as shown in FIG. These spheres 4 are formed to have a diameter slightly larger than the diameter of the through hole 3, and the same material as that of the flat plate 1 is used as the material. The step of mounting the spherical body 4 in each through hole 3 is, for example, as shown in FIG. 3, one end of the flat plate 1 is lifted slightly upward by using the lifting drive device 10, and slightly tilted,
A method of flowing a large number of spheres 4 on the flat plate 1 from one end side,
As shown in FIG. 4, a large number of spheres 4 are placed on the flat plate 1,
Air is sucked in the direction B by the suction device 11 arranged below the flat plate 1, and the spherical body 4 is sucked in the through hole 3 by this, and then the lifting drive device 10 lifts one end side in the direction of arrow A. Various methods such as inclining the flat plate 1 and removing other extra spherical bodies 4 may be used.

When the step of placing the sphere 4 in the through hole 3 formed in the flat plate 1 as described above is completed, then the sphere 4 is fixed at that position. In the fixing process of the sphere, for example, as shown in FIG. 5, laser light 2 is irradiated from the back surface side of the flat plate 1 to melt the portion where the sphere 4 and the through hole 3 are in contact with each other, and the through hole 3 6 may be a method of welding the wall surface and the spherical body 4 to each other, or a method of sticking (laminating) the sheet body 5 on the surface of the flat plate 1 as shown in FIG. If the method of fixing the flat plate 1 and the spherical body 4 by sticking the sheet body 5 in this way is adopted, the material of the flat plate 1 and the material of the spherical body 4 can be different from each other. . According to the guide plate 6 manufactured by such a manufacturing method, since the through hole 3 formed in the flat plate 1 is formed through the laser light 2, the flat plate 1 is formed.
All of them have the same shape without causing distortion, and the projection lengths of the spheres 4 mounted and fixed in the through holes 3 are all uniform without variation. It is possible to make sure visually impaired people understand.

Although the guide plate 6 according to the above-described embodiment has been illustrated and described in which the through hole 3 is formed in the flat plate 1 by using the laser beam 2, the guide plate according to the present invention is not necessarily a convex member. As shown in FIG. 7, not only the through-holes are formed as the mounting portions, but also a plurality of recesses 21 are formed on the upper surface of the flat plate 20, and a spherical body 22 is adhered to these recesses 21, which is a guide plate 23. Is also good.

Further, the guide plates 6 and 20 according to each of the above embodiments.

Alternatively, the recesses 21 are formed and the spherical bodies 4 and 22 are fixed to the recesses 21. However, the guide plate according to the present invention is
Not only those corresponding to Braille but also those formed with characters such as Katakana or alphabet. For example, the guide plate 30 shown in FIG.
The outline corresponding to the office and the numbers, alphabets and katakana are displayed by the sphere 32, and the plurality of spheres 32 representing the outline of the office are formed on the flat plate 31 as shown in FIG. A large number of spheres 32 are arranged and fixed in a groove 33 formed on the surface, and the numbers, alphabets and katakana are such that the spheres 32 are linear or curved along a slit 34 as shown in FIG. It is fixed in parallel with. The spherical bodies 32 may be fixed by attaching a sheet body to the upper surface of the flat plate 31 as shown in FIG. 6 referred to in the description of the embodiment. According to the guide plate 30 having the above-described structure, even a visually impaired person who has not mastered Braille yet can reliably understand the meaning, that is, the outline of this office, the position of the toilet, or the position of the door. be able to.

In the description of each of the above-mentioned embodiments, a spherical body is shown as an example of the convex member constituting the present invention, but the convex member is not limited to the spherical body, and for example, the guide shown in FIG. A large number of round rivets 40 may be used like the plate 43. That is, the guide plate 43 is configured such that the shaft portion 40a of each round rivet 40 is inserted and fixed in the through hole 42 formed in the flat plate 41, and the head portion 40b projects from the flat plate 41. Alternatively, like the guide plate 48 shown in FIG. 12, a large number of pins 45 having a slightly rounded tip 45a like a bullet may be used. That is,
The guide plate 48 is formed by inserting and fixing each of the pins 45 into a large number of recesses 47 formed in the flat plate 46.
