Description

  The present invention relates to a guiding block used for guiding a pedestrian or the like under no illumination during a power failure or the like.

In subway premises (for example, stairs, passages, platforms), other public facilities, sidewalks, etc., lay blocks with linear or dotted projections to guide visually impaired persons such as blind people Is widely practiced. In this case, a visually handicapped person can recognize the position and shape of the convex part on the block by the feel of the tip of the cane or the sole of the foot, and can know the direction to advance and the place to stop and pay attention to. .
On the other hand, a phosphorescent material is known as a material that stores light under sunlight or artificial lighting and then emits light when it becomes dark. As a tile using this phosphorescent material, for example, it is a guide tile provided with a non-slip piece for slipping on the surface of the tile body, and separately from the non-slip piece, a light-emitting display piece containing a phosphorescent agent is A guidance tile characterized by being provided on the surface of a tile body has been proposed (Patent Document 1).

JP 2009-150163 A

As described above, the guidance tile described in Patent Document 1 has a non-slip piece for slipping and a light-emitting display piece containing a phosphorescent agent. Patent Document 1 exemplifies an end portion of a platform and a staircase as an application of this guidance tile.
However, tiles having non-slip pieces for slipping are usually provided only in places where there is a high risk of falling over, such as the edge of the platform on the vehicle traffic side or stairs. Therefore, it is considered difficult to promptly and reliably guide a large number of people including a healthy person waiting for a train on a platform to the ground during a power failure in a subway premises or the like. In particular, when a guide tile having a light-emitting display piece containing a phosphorescent agent is arranged at the edge of the platform on the vehicle traffic side, walking along the light-emitting display piece in the dark during an emergency It is considered that there is a risk of falling from the platform to the track side because it walks on the outside (track side) of the white line or yellow line for preventing contact with the track.
An object of the present invention is to provide a guiding block that can quickly, safely and reliably guide a large number of persons including healthy persons under no illumination such as during a power failure.

  As a result of intensive studies to solve the above-mentioned problems, the present inventor has formed a light emitting display unit including a phosphorescent material on a convex part or a region in the vicinity thereof that has been widely adopted so far to guide a visually impaired person. For example, many people, including healthy people, can evacuate to the ground quickly, safely, and reliably using light emitted from the light-emitting display as a landmark, for example, on a subway platform, etc. The present invention was completed.

That is, the present invention provides the following [1] to [6].
[1] A guidance block having one or more convex portions for guiding a visually handicapped person, wherein a light emitting display portion including a phosphorescent material is formed on at least one of the convex portions and the vicinity thereof. A guide block characterized by that.
[2] The guide block according to [1], wherein the light-emitting display unit is formed of a coating film including a phosphorescent material, a tape including the phosphorescent material, or a molded body including the phosphorescent material.
[3] The guiding block according to [1] or [2], wherein the light emitting display section is formed at least in a region near the convex portion.
[4] The guidance block according to any one of [1] to [3], wherein the convex portion is a linear or dotted convex portion.
[5] The guidance block according to any one of [1] to [4], wherein the upper surface of the guidance block other than the light emitting display unit is colored for a low vision person.
[6] The guidance block is a platform edge warning block of a station platform, a block for a station passage, a block for an underground shopping street, a passage in a commercial facility or business facility used by an unspecified number of persons, or The guide block according to any one of [1] to [5], which is a block for a floor or a block for an outdoor sidewalk.

According to the present invention, the guidance block having one or more convex parts for guiding the visually impaired is selected as the place where the light emitting display part including the phosphorescent material is formed. A light emitting display portion including a phosphorescent material can be formed over the entire path from the exit to the ground. Therefore, for example, in the event of a power failure, a large number of persons including healthy persons can evacuate to the ground quickly, safely, and reliably by using the light emitted from the light emitting display unit as a landmark in the subway station. In particular, the guidance block for guiding the visually impaired is arranged inside the white line or yellow line for preventing contact with the train (the side away from the track). Forming the lane also prevents a pedestrian from accidentally falling from the platform to the track side in the darkness during a power failure.
According to the present invention, since the light emitting display part including the phosphorescent material is formed on the convex part for guiding the visually impaired person or the vicinity thereof, it is conspicuous under no illumination (in the dark) such as at the time of a power failure. It is easy to see. In particular, the visibility is good when the light emitting display part is formed on the upper surface of the convex part. In addition, the upper surface of the guide block other than the light-emitting display portion can be colored yellow or the like for the low vision person as in the conventional case, so that the function of guiding the low vision person under normal illumination is not impaired. .
The guide block of the present invention may be obtained by constructing an existing guide block for a visually impaired person, or when a guide block for a visually impaired person is newly manufactured, You may manufacture by adding the process of forming a light emission display part.

It is a perspective view which shows an example of the platform of a train including the block for guidance of this invention. It is sectional drawing which shows the various form of the light emission display part of the block for guidance of this invention. FIG.

Hereinafter, embodiments of the guide block according to the present invention will be described with reference to the drawings.
In FIG. 1, the home edge block 1 is arranged facing a space through which a train vehicle passes, and prevents a person getting on and off the vehicle from slipping and falling down. Convex part 2 is provided. In addition, the linear convex part 2 is formed with rubber | gum etc., for example. The main body of the home edge block 1 is formed of, for example, mortar,
On the inner side block (side away from the track) adjacent to the home edge block 1, a line 3 for preventing contact with the vehicle is formed as a coating film colored white or yellow.
Inside the block having the line 3 for preventing contact with the vehicle, the home edge warning blocks 5 and 6 for visually handicapped persons are disposed with the block 4 interposed therebetween.
Of these, the home edge warning block 5 is the guiding block of the present invention.

The home edge warning block 5 is for notifying a visually handicapped person that the edge of the platform is near. In general, the home edge warning block 5 has dot-like convex portions 7 (usually 25 pieces) and linear convex portions 8 (usually one piece), and the side where the dot-like convex portions 7 are located is The side near the edge of the home and where the linear convex portion 8 (also referred to as “inward line”) is located is the side away from the edge of the home. In addition, the structure of such a home edge warning block 5 has been changed in recent years from a structure having only point-like convex portions for the purpose of improving the safety of the visually impaired.
The dimensions of the dot-like convex part 7 are, for example, a height of 5 to 6 mm, an upper surface diameter of 12 to 14 mm, and a lower surface diameter of 22 to 24 mm. The dimensions of the linear protrusion 8 are, for example, 5 to 6 mm in height, 17 to 19 mm in the length of the upper side in the short direction, 27 to 29 mm in the length of the lower side in the short direction, and length in the longitudinal direction. Is 270 mm or more. In addition, as a linear convex part, there exists a short thing whose length of a longitudinal direction is less than 270 mm. Such a short length in the longitudinal direction is also included in the “linear convex portion” in this specification.
In general, in a block having a dot-like or linear convex part for guiding a visually impaired person, the dot-like convex part means "stop" or "caution", and the linear convex part is Means “advance”. In recent years, the shape and size of the protrusions (protrusions) for each of the block having point-like protrusions (dot-like block), the block having line-like protrusions (linear block), and the home edge warning block The JIS standard regarding the length and the arrangement is defined as “JIS T9251 Shapes and dimensions of protrusions such as blocks for guiding the visually impaired and their arrangements”.

In FIG. 1, the home edge warning block 5 includes a linear protrusion 8 and a region in the vicinity of the linear protrusion 8 (specifically, extends in the longitudinal direction adjacent to the linear protrusion 8. In the belt-like region on the flat surface of the block 5, the coating films 10, 11, and 12 containing the phosphorescent material are provided.
2A is a conceptual view in which the coatings 10, 11, and 12 of the home edge warning block 5 are cut in the short direction (direction perpendicular to the longitudinal direction) of the linear convex portion 8 in FIG. As a cross-sectional view. In FIG. 2A, the linear convex portion 8 is formed integrally with the block body 13 having a rectangular cross section. A coating film 10 containing a phosphorescent material is formed on the upper surface of the linear protrusion 8. A coating film 11 containing a phosphorescent material is formed on the upper surface of the block main body 13 adjacent to the side close to the edge of the home of the linear protrusion 8. A coating film 12 containing a phosphorescent material is formed on the upper surface of the block main body 13 adjacent to the side of the linear convex portion 8 away from the edge of the home.
In FIG. 2, the block main body 13 and the linear protrusion 8 are usually formed integrally using a material such as mortar or concrete. However, for the sake of convenience of explanation, the base layer portion having a certain thickness is used. The block main body 13 is distinguished from each other.
In the present invention, it is not essential to form all of the coating films 10, 11 and 12, and one or more selected from the coating films 10, 11 and 12 may be formed. For example, only the coating film 10 may be formed, only the coating films 11 and 12 may be formed, only one of the coating film 11 and the coating film 12 may be formed, or It may be formed as a combination of the coating film 10 and any one of the coating film 11 and the coating film 12. The same applies to the cases of (b) and (c) in FIG.
As the phosphorescent material used in the present invention, any commercially available material can be used. Examples of the phosphorescent material constituting the phosphorescent material include strontium aluminate, zinc sulfide and the like.

The coating film containing a phosphorescent material can be formed by the following procedures (A) to (E), for example.
(A) A masking tape is applied around the area where the coating film containing the phosphorescent material is formed.
(B) A liquid anchor agent is applied to an area surrounded by a masking tape (an area where a coating film containing a phosphorescent material is formed) and dried to form an anchor layer.
(C) On the anchor layer, an aqueous paint containing a phosphorescent material is applied and dried to form a phosphorescent material-containing layer.
(D) A polymer-containing liquid is applied on the phosphorescent material-containing layer and dried to form a protective layer.
(E) Remove the masking tape.
The protective layer (d) is for suppressing wear and the like of the light emitting display portion.
In addition, the coating film containing a phosphorescent material may be formed at the time of manufacture of the guide block, or may be formed on an existing guide block. The same applies to the cases of (b) and (c) in FIG.

In this invention, when the light emission display part (For example, coating film containing a phosphorescent material) is formed in the upper surface of the linear convex part 8, it is easy to visually recognize under no illumination at the time of a power failure etc. There is. Moreover, in this invention, the light emission display part (For example, coating film containing a phosphorescent material) is a strip | belt-shaped adjacent area | region (especially without leaving a space | interval within 5 mm, without leaving a space | interval). In the normal state, pedestrian shoes or the like may come into contact with the linear convex portion 8 and wear the coating film on the convex portion 8, but the linear shape Since it does not contact the vicinity area (especially adjacent strip-shaped area) of the convex part 8, the light emitting display part (for example, a coating film containing a phosphorescent material) is hardly worn.
In the present invention, the light emitting display portion is formed at least in one of the convex portion and the vicinity of the convex portion (particularly, the region adjacent to the convex portion with no gap or within 5 mm). It only has to be. However, it is preferable that the light emitting display part is formed in both the convex part and the vicinity of the convex part.

As the light emitting display section of the home edge warning block 5, the form (b) or (c) in FIG. 2 may be adopted instead of (a) in FIG.
In FIG. 2B, a tape 14 containing a phosphorescent material is affixed to the upper surface of the linear protrusion 8 on the block body 13. Tapes 15 and 16 containing a phosphorescent material are affixed to the upper surface of the block main body 13 that is a region in the vicinity of the linear convex portion 8.
When the tape containing the phosphorescent material does not have an adhesive layer on the surface of the tape body, the tape is applied after applying a liquid primer (adhesive). When the adhesive layer is provided on one side of the main body of the tape containing the phosphorescent material, the tape containing the phosphorescent material is directly affixed on the application target surface.
In FIG. 2C, a concave portion is formed on the upper surface of the linear convex portion 21 on the block body 20, and a molded body 22 containing a phosphorescent material is disposed in the concave portion. . Concave portions are also formed on the upper surface of the block main body 20, which is a region in the vicinity of the linear convex portion 21, and molded bodies 23 and 24 containing a phosphorescent material are disposed in these concave portions. In addition, when forming the light emission display part in the existing guidance block, the recessed part for fitting a light emission display part is formed using a concrete cutter etc., and the molded object containing a luminous material in this recessed part ( The light emitting display portion) may be fitted. Further, in FIG. 2C, there seems to be a step between the colored coating film 9 for low vision and the molded bodies 23 and 24 containing the phosphorescent material, but this exaggerates the drawing conceptually. This is because of the description, and since the thickness of the colored coating film 9 is small, there are actually almost no steps.
Examples of the molded body including the phosphorescent material include a ceramic molded body including the phosphorescent material.

The upper surface of the home edge warning block 5 other than the light-emitting display portion is formed by a colored coating film 9 for low vision. The color of the colored coating film 9 is preferably a color (for example, yellow) that is easily visible to a low vision person.
In the home edge warning block 5 shown in FIG. 1, a colored coating film 9 for low vision is formed on the entire upper surface of the block 5 other than the light emitting display portion (the linear convex portion 8 and its neighboring region). Therefore, the function of guiding the weak eyesight is not impaired as compared with the case where only the colored coating film for the weak eyesight is formed without the light emitting display portion.
The block body 13 of the home edge warning block 5 can be formed, for example, as a laminate of a surface layer having a thickness of about 10 mm and a base layer having a thickness of about 20 mm. In this case, a material (for example, mortar, concrete, resin concrete, etc.) containing a pigment for low vision (for example, yellow) can be used as the material for only the surface layer or the material for both the surface layer and the base layer. Thus, when a material containing a pigment for low vision is used as a material for forming the portion including at least the upper surface of the block body, the colored coating on the block body can be omitted. In this case, even if the upper surface of the block main body is worn by pedestrian shoes or the like, the color for low vision (for example, yellow) can be maintained.
In FIG. 1, home edge warning blocks 6 arranged on both sides of the home edge warning block 5 are replaced with coating films 10, 11, and 12 containing a phosphorescent material, and a colored coating film 9 for a low vision person. Except for being formed, it has the same structure as the home edge warning block 5, and the entire upper surface of the block 6 is formed of a colored coating 9 for low vision.
Thus, the home edge warning block 6 having no light emitting display part and the home edge warning block 5 having a light emitting display part can be alternately arranged as shown in FIG. 1, for example.

The light-emitting display part of the home edge warning block 5 is a point-like convex part 7 and its vicinity area (in particular, with no space between them, together with the linear convex part 8 or instead of the linear convex part 8. Or it can also form in at least one of the cyclic | annular area | region adjacent to the convex part 7 at intervals within 5 mm.
In the case where the light emitting display portion is formed in the dot-like protrusions 7 or in the vicinity thereof, for example, in FIG. 1, for example, five dot-like protrusions 7 arranged in the same direction as the longitudinal direction of the line-like protrusions 8 A light-emitting display portion can be formed. In this case, a colored coating for low vision is formed on the other four rows (20 in total) of the dot-like convex portions 7. For example, the home edge warning block in which the light emitting display part is formed on the dot-like convex part 7 and the home edge warning block 6 having no light emitting display part can be alternately arranged.
However, considering the ease of forming the light-emitting display portion, it is desirable to form the light-emitting display portion in the linear convex portion 8 or in the vicinity thereof.

In addition to the home edge warning block 5 shown in FIG. 1, the present invention can be applied to a guide block having only a large number of point-like convex portions and a guide block having only a plurality of linear convex portions. .
In general, guide blocks for visually impaired persons are continuously laid from the entrance on the ground to the platform entrance / exit in a subway or the like. Therefore, if all of the guidance blocks for the visually impaired are made to have a light-emitting display that includes a phosphorescent material, for example, when a power failure occurs and the lighting in the station is turned off, the train waits on the platform. A person or the like can evacuate to the ground quickly, safely, and reliably along the light emitting display unit.
In addition, when the guidance block of the present invention is laid outdoors, when a power failure occurs and the road lighting and signals are extinguished and there is no lighting (darkness), the pedestrian The sidewalk can be safely passed along the light emitting display portion.

  The guidance block of the present invention can be used for a platform edge warning block of a station platform, a block for a station passage, a block for an underground shopping street, a commercial facility used by an unspecified number of people (for example, a department store, a hotel, a supermarket). Etc.) or a block for a passage or floor in a business facility (for example, an office, a factory, a government office, a public hall, a cultural hall, etc.), a block for an outdoor sidewalk, or the like.
