Description

  The present invention relates to a guide plate installed on a floor surface or wall surface through which a person passes to guide a person's destination, and has a large number of convex portions on the surface for a visually impaired person and is installed on a walking surface. In addition to guide plates such as braille sheets and braille blocks used in the dark, in the dark, pictograms depicting the running of people to show the presence of emergency exits to visually impaired people, and other destination directions appropriate to people The present invention relates to a guide plate and a manufacturing method thereof.

  The guide plate has a convex portion on the surface thereof, and is installed in public facilities such as roads and stations for the visually impaired. In general, a guide plate is a linear and trapezoidal convex part arranged in parallel to represent the direction of travel, guiding a person to a destination, or a dotted frustoconical convex part like a Braille plate. There are known parts that display warnings and positions. The visually impaired person obtains information by feeling the unevenness of the guide plate with the sole of the foot.

  In recent years, there is a problem that an object or the like is left on such a guide plate and hinders the passage of the visually impaired. For such problems, background images, characters, figures, etc. are placed on the surface of induction plates such as Braille plates and Braille blocks in order to appeal to visually-impaired people and appeal to them. A guidance technique for displaying is known (for example, see Patent Document 1).

  In addition, a guide plate having only information for visually handicapped persons displays information for a visually impaired person as one member (for example, refer to Patent Document 2), or a letter plate on a guide plate such as a Braille plate or a Braille block. A guide plate (see, for example, Patent Document 3) that can be guided to a visually healthy person even in a dark place by using a phosphorescent agent while applying a pattern or a figure has been studied.

  However, in the conventional induction plates described in Patent Document 1 and Patent Document 3, since characters, figures, etc. are directly displayed on the surface by printing or the like, they are rubbed and displayed when a person walks. There is a problem that disappears. Some are installed so that they can be guided when a disaster occurs. However, when a disaster actually occurs, the display on the surface disappears, and there is a possibility that a visually impaired person cannot be guided in a dark place.

  In addition, as described in Patent Document 2, there are some that protect the display from friction caused by human walking by adhering a transparent sheet on the display of characters, figures, etc. As a result, the transparent sheet may peel off, and there is a risk that the visually impaired person will go to the sheet that is about to peel off. In addition, after the sheet is peeled off, the display may disappear due to friction as described above.

  In addition, as described in Patent Document 3, if the phosphorescent agent is applied to the braille block, or if characters, patterns, arrows, etc. are applied to the portion without the braille, the braille block is made of rubber. In such a case, there is a possibility that the phosphorescent agent or characters may be peeled off.

  The present invention has been made in view of the above-mentioned problems, and can provide not only appropriate guidance display for visually impaired persons, but also for general visual healthy persons, particularly for visually healthy persons such as nursing homes. Another object of the present invention is to provide a guide plate and a method for manufacturing the guide plate, in which the guide display does not easily disappear in a dark place at the time of occurrence of a disaster.

  In order to achieve the above object, the first characteristic configuration of the guide plate according to the present invention is a destination guide plate that has a convex portion on the surface and can be used even in a dark place, and is a guide display mainly composed of synthetic rubber. The member is attached to the surface of the plate body mainly composed of a synthetic rubber containing at least one type of molecular structural unit constituting the synthetic rubber.

That is, according to this configuration, the display on the guide plate is different from printing or the like, and the guide display member is attached to the plate body, so that it does not disappear even by friction such as walking.
In addition, the induction display member is attached to the plate body mainly composed of a synthetic rubber containing at least one type of molecular structural unit of the synthetic rubber constituting the induction display member. Even if it is not used, it can be firmly bonded. Therefore, there is no possibility that the guide display member may be peeled off due to deterioration of the adhesive over time.

  The 2nd characteristic structure of the induction | guidance | derivation plate which concerns on this invention exists in the point whose said induction | guidance | derivation display member has as a main component any one of ethylene propylene rubber, butadiene rubber, and styrene butadiene rubber.

  That is, according to this configuration, ethylene propylene rubber, butadiene rubber, and styrene butadiene rubber are suitable for induction plates because they have good friction resistance. In particular, ethylene propylene rubber is excellent in weather resistance in addition to wear resistance, and is therefore suitable for the case where the induction plate is used outdoors.

  The 3rd characteristic structure of the induction | guidance | derivation plate which concerns on this invention exists in the point by which the luminous agent is mix | blended with the said induction | guidance | derivation display member.

  That is, according to this configuration, the guidance display member can be visually recognized even in the case of an emergency such as the occurrence of a disaster even when the surroundings are dark due to a power failure or the like. For this reason, it is generally possible to guide people to an emergency exit or the like by guidance display.

  A fourth characteristic configuration of the induction plate according to the present invention is that the hue of the induction display member is the same system as the hue of the plate body.

  That is, according to this configuration, for example, even if the guidance display member is displayed in advance so that it can be guided to an emergency exit or the like, the guidance display member is made inconspicuous in a bright state such as normal. Can do. And people can be guided only when the surroundings become dark due to a power failure or the like.

  A fifth characteristic configuration of the guide plate according to the present invention is that a part of the convex portion is formed on the front surface or the back surface of the guide display member.

  That is, according to this structure, a convex part can be formed in the surface thru | or back surface of a guidance display member instead of the convex part of a plate main body. For this reason, the shape and attachment position of a guidance display member are not limited only to the part which does not have the convex part of a plate main body. That is, an arbitrary shape of the guidance display member can be attached to an arbitrary position on the plate body.

  The characteristic means of the method for manufacturing the induction plate according to the present invention includes an induction display member mainly composed of a vulcanized synthetic rubber previously vulcanized with an organic peroxide, and a molecular structural unit constituting the synthetic rubber. Then, the unvulcanized synthetic rubber is vulcanized by superimposing a plate body composed mainly of an unvulcanized synthetic rubber containing an organic peroxide vulcanizing agent and heating it at a constant pressure. The guide display member is attached to the surface of the plate body.

  That is, according to this means, the guide display member can be attached to the plate body without using an adhesive or the like. For this reason, there is no possibility that the guidance display member may be peeled off due to deterioration of the adhesive over time.

  In addition, as a method for producing the induction plate according to the present invention, an induction display member mainly composed of an unvulcanized synthetic rubber compounded with an organic peroxide vulcanizing agent, and a molecular structural unit constituting the synthetic rubber The unvulcanized synthetic rubber is vulcanized by superimposing a plate body mainly composed of a vulcanized synthetic rubber previously vulcanized with an organic peroxide and heating at a constant pressure. The guide display member may be attached to the surface of the plate body. A similar effect can be obtained by this means.

  The induction plate according to the present invention is a destination induction plate that has a convex portion on the surface and can be used even in a dark place, and an induction display member mainly composed of synthetic rubber is a molecular structural unit constituting the synthetic rubber. Are attached to the surface of a plate body mainly composed of a synthetic rubber containing at least one kind of the same molecular structural unit. As a result, since the guide display member is attached to the plate body, it does not disappear even by friction such as walking, and it can be firmly bonded without using an adhesive. There is no possibility that the guide display member may be peeled off due to the above.

  Hereinafter, an example of the guide plate according to the present invention will be described with reference to FIGS. That is, the guide plate is a plate made of synthetic rubber whose main component is 30 cm in length and width, and is a point-like shape that hits the pedestrian's sole on the plate body 1 and has a truncated cone shape with D1 of 22 mm and D2 of 12 mm. The portions 2 are formed in a matrix of 5 rows and 5 rows, and an arrow-shaped guidance display member 3 for guiding a healthy visual person is integrally disposed at the center. And this guidance plate is laid and used for warning or a position display in a sidewalk, a station building, the inside of a building, and other floor materials in walking of a visually handicapped person. In addition, although the arrow shape of the guidance | indication display member 3 is not specifically limited, For example, the shape as shown to FIGS. 5-8 is illustrated. T1 is 7 mm and T2 is 5 mm.

  Further, another example of the guide plate according to the present invention is a plate mainly composed of synthetic rubber having a length and width of 30 cm as shown in FIGS. 3 and 4, and a line that hits the pedestrian's sole on the plate body 1. The trapezoidal convex portions 2 having W1 of 27 mm and W2 of 17 mm are arranged in four rows, and an arrow-shaped guide display member 3 for guiding a healthy visual person is integrally formed in the central portion. It is arranged. And this guidance plate is laid and used for the direction indication in a straight walk on a sidewalk, a station building, the inside of a building, and other floor materials in walking of a visually handicapped person. In addition, although the arrow shape of the guidance | indication display member 3 is not specifically limited, For example, the shape as shown to FIGS. 9-12 is illustrated. T3 is 7 mm.

The plate body 1 is mainly composed of a synthetic rubber containing at least one kind of molecular structural unit among the molecular structural units constituting the synthetic rubber which is the main component of the guide display member 3. The type of the synthetic rubber is not particularly limited, but is preferably wear-resistant because a person walks on the synthetic rubber. From this viewpoint, ethylene propylene rubber, butadiene rubber, styrene butadiene are preferable. What has either rubber | gum as a main component is preferable. And especially when using the induction | guidance | derivation plate of this invention outdoors, what has ethylene propylene rubber which has a weather resistance further as a main component is preferable. Of course, for example, a plurality of synthetic rubbers such as ethylene propylene rubber and styrene butadiene rubber may be mixed and used.
Therefore, in the case where a material mainly composed of styrene butadiene rubber is applied to the induction display member 3, the plate body 1 has butadiene made of butadiene rubber which is a part of the molecular structural unit of styrene butadiene rubber. A rubber or one having a styrene butadiene rubber itself having the same molecular structural unit as a main component can be applied. Similarly, in the case where a material containing ethylene propylene rubber or butadiene rubber as a main component is applied to the induction display member 3, the plate main body 1 has the same molecular structural unit as the ethylene propylene rubber. Those having ethylene butadiene rubber itself as the main component, and butadiene rubber having the same molecular structure unit as the main component, or part of the molecular structure unit. The main component is styrene butadiene rubber containing butadiene rubber.
Since the main components of the synthetic rubber having the same molecular structural unit as described above can be firmly bonded to each other without using an adhesive, the plate main body 1 and the guide display member 3 can be combined. An induction plate that is difficult to peel off can be obtained.

Further, the guide display member 3 can be blended with a luminous agent. That is, by blending the phosphorescent agent, the shape of the guidance display member 3 can be made visible even when the surroundings become dark due to a power failure or the like in an emergency such as a disaster. It is possible to guide people to an emergency exit or the like by using a guidance display indicating the presence of an emergency exit such as a pictogram depicting a person running as well as an arrow.
In addition, the kind of luminous agent to mix is not specifically limited, A conventionally well-known luminous agent can be applied. Also, the particle size of the phosphorescent agent is not particularly limited, but the larger the particle size, the greater the phosphorescent property, but the wear resistance is lowered, so the average particle size is preferably about 2 to 60 μm. The blending ratio of the phosphorescent agent is preferably 10 to 60 parts with respect to 100 parts of the synthetic rubber. However, if the blending ratio is increased, there is a concern that the physical properties of the rubber may be lowered. More preferred.

  In the case where a phosphorescent agent is blended in the guide display member 3, it is preferable that the rubber itself has transparency that allows light to pass through. From this point of view, the main component is ethylene propylene rubber or butadiene rubber as described above. Can be preferably applied. Furthermore, in order to improve the transparency of the rubber, about 40 to 80 parts of silica can be mixed. In addition, when vulcanizing such an induction display member 3, in the case of sulfur vulcanization from the viewpoint of maintaining transparency, the vulcanizing agent is transferred to the surface or discolored. It is preferable to carry out using.

  Further, when a phosphorescent agent is blended in the guidance display member 3, the hue of the guidance display member 3 can be made the same system as the hue of the plate body 1. For example, even if the guidance display member 3 is displayed in advance so that it can be guided to an emergency exit or the like, people are not affected by the guidance display on the guidance plate at normal times because the surroundings are not noticeable in a bright state. And it becomes visible only when the surroundings become dark due to a power failure or the like, and people can be guided. That is, a preferred example of the embodiment of the induction plate of the present invention is, as shown in FIG. 13, laid on a flooring such as a building, and when the surroundings become dark due to a power failure or the like in the event of a disaster, etc. It is exclusively for visually handicapped people in normal times and can be used for common use with healthy people in an emergency.

  A convex portion 2 having the same component as the plate main body 1 can be formed on the surface of the guide display member 3, or the same component as that of the guide display member 3 can be used. That is, since the convex portion 2 can be formed on the surface of the guide display member 3 instead of the convex portion 2 of the plate body 1, the shape and mounting position of the guide display member 3 has the convex portion 2 of the plate body 1. The guide display member 3 having an arbitrary shape can be attached to an arbitrary position on the plate body 1 without being limited to only the portion that is not. That is, the protrusion 2 may be formed at a position of the original guide plate before or after the guide display member 3 is attached to the plate body 1. Moreover, the convex part 2 which consists of the component similar to the guidance display member 3 can also be formed in the back surface of the guidance display member 3. FIG. When the convex part 2 which consists of the component similar to the guidance display member 3 is formed in the surface and back surface of the guidance display member 3, the convex part 2 increases the luminous amount of the guidance display member 3, and the emitted light amount of the convex part 2. However, different colors and patterns can be formed by making the composition of the phosphorescent agent different.

  An example of the method of manufacturing the induction plate according to the present invention is as follows. A plate body 1 mainly composed of an unvulcanized synthetic rubber compounded with an organic peroxide vulcanizing agent, and an organic peroxide in advance. The induction display member 3 containing vulcanized synthetic rubber as a main component is overlapped and heated at a constant pressure to vulcanize the unvulcanized synthetic rubber, and the induction display member 3 is formed on the surface of the plate body 1. Is to be attached. Accordingly, the guide display member can be attached to the plate body without using an adhesive or the like, and therefore the guide display member is not peeled off due to deterioration of the adhesive over time or the like.

The guide display member 3 is formed of a synthetic rubber preliminarily blended with an organic peroxide vulcanizing agent as a main component, and an arbitrary shape having a guide display function is formed. And it arrange | positions to a metal mold | die, processes with a press molding machine, and makes an organic peroxide vulcanize | cure. Vulcanization conditions are not particularly limited. For example, vulcanization can be carried out satisfactorily by treating at a pressure of 8 to 10 MPa at 170 ° C. for about 10 minutes. Moreover, it is preferable to mix | blend about 1.5-2 parts of organic peroxide vulcanizing agents.
When the convex portion 2 is formed on the surface of the guide display member 3 and the convex portion 2 has the same component as that of the plate body, the guide display member 3 and the convex portion 2 are arranged in a mold and simultaneously This can be done by vulcanization. Moreover, when the convex part 2 is made into the component similar to the induction | guidance | derivation display member 3, it arrange | positions the induction | guidance | derivation display member 3 which previously formed the convex part 2 on the surface by the method similar to the above, and vulcanizes it. This can be done. Even when the convex portion 2 having the same component as that of the guidance display member is formed on the back surface of the guidance display member 3, the guidance display member 3 having the projection 2 formed on the surface in advance is disposed in the mold in the same manner. Can be formed.

Then, as described above, the plate body 1 mainly composed of synthetic rubber preliminarily blended with the organic peroxide vulcanizing agent is formed, and the organic peroxide vulcanized induction display member 3 is overlaid on the mold. The vulcanization treatment can be preferably performed under the same conditions as the conditions for treating the induction display member 3 in a press molding machine.
In the above description, the case where the unvulcanized synthetic rubber is used as the plate body 1 and the vulcanized synthetic rubber is used as the guide display member 3 has been described. Even if a vulcanized synthetic rubber is used and an unvulcanized synthetic rubber is used as the induction display member 3, the induction plate can be manufactured in the same manner.
In addition, the convex part 2 which the induction | guidance | derivation plate main body 1 has can be favorably formed by performing said vulcanization process with the plate main body 1 and the induction | guidance | derivation display member 3. FIG.

Thus, the unvulcanized rubber and the vulcanized rubber are combined and vulcanized, whereby both can be firmly bonded without using an adhesive or the like.
