Description

Technical Field

[0001] Braille blocks for guiding visually impaired persons, Braille tiles for guiding visually impaired persons, or Braille sheets for guiding visually impaired persons (hereinafter collectively referred to as Braille guiding blocks) are already widespread, and the special uneven pattern (hereinafter referred to as the uneven part that people touch) on the surface that people touch is easy for anyone to understand, but there are still many inconveniences left.

[0002] Regarding Braille guiding blocks that enable visually impaired persons to recognize the center or both ends of the Braille guiding blocks regardless of the weather, and at intersections, the Braille guiding blocks can guide the visually impaired persons without interruption, and on the platform, the Braille guiding blocks can ensure greater safety for the visually impaired persons.

Background Art

[0003] On rainy or snowy days, even for healthy people, the hems of their trousers or skirts may get wet due to the splashing of their own shoes or the wet parts of the umbrellas they hold. In some cases, mud or the like may stick to other people's clothes.

[0004] Naturally, the same is true for the actions of visually impaired persons. On rainy or snowy days, the hems of their trousers or skirts may get wet due to the splashing of their own shoes or the wet parts of the umbrellas they hold. In some cases, mud or the like may stick to other people's clothes.

[0005] On rainy or snowy days, unlike the way healthy people take a detour along the sidewalk while avoiding puddles, visually impaired persons have no choice but to follow the route where the Braille guiding blocks are installed because they cannot choose a path with less splashing. If puddles form at the installation locations of the Braille guiding blocks, the shoes of the visually impaired persons will get wet all the way through, and it will take a long time for the installation locations of the Braille guiding blocks to dry.

[0006] One of the reasons why sand is used during the construction of the sidewalk by the contractor or the client constructing the Braille guiding blocks is that it can be absorbed by the ground in light rain or snowfall. However, once heavy rain or snow occurs, the water absorption capacity of the sand around the Braille guiding blocks and the surrounding soil is inferior, resulting in puddles remaining.

[0007] For visually impaired people, on rainy or snowy days, their clothes and footwear get wet more easily compared to healthy people. Or, at intersections for visually impaired people, the path guidance is interrupted throughout the day. Or, on platforms, the safety of visually impaired people remains insufficient. Thus, for visually impaired people, it is as difficult as climbing a steep hill to be able to walk outside without any resistance like healthy people and enjoy work, recreation, and shopping.

[0010] Japanese Unexamined Patent Application Publication No. 2001 - 271315 provides an invention of a multi - colored Braille guiding block or a walking guide with enhanced distinctiveness and visibility, but the invention to be applied is different from the present invention and is not applicable.

[0011] JP-A-2002-194717 is an invention that provides a braille sign sheet that can be easily laid and removed on a temporary sidewalk at a construction site or the like and can ensure smooth passage for visually impaired persons. However, the invention to be applied is different from the present invention and does not apply.

Advantages of the Invention

Embodiments for Carrying Out the Invention

Examples

[0014] The details of the present invention will be described using representative drawings.

[0015] Taking the uneven portion that a person touches on the Braille guiding block 1 as the XY plane, in the uneven portion that a person touches on the XY plane of the aforementioned Braille guiding block 1, the line segment connecting the origin of the X-axis and the Y-axis and the vertical component of the midpoint of the aforementioned Y-axis has a depression angle when viewed from the aforementioned X-axis, and the vertical component of the midpoint of the aforementioned Y-axis and the end point of the aforementioned Y-axis return to the original aforementioned XY plane at the uneven portion that a person touches on the aforementioned Braille guiding block 1, creating a sunken step on the aforementioned XY plane at the uneven portion that a person touches on the aforementioned Braille guiding block 1, and arranging it so that water flows to the lowest step of the uneven portion that a person touches on the aforementioned Braille guiding block 1 (Fig. 3).

[0016] Taking the uneven portion that a person touches on the Braille guiding block 3 as the XY plane, in the uneven portion that a person touches on the XY plane of the aforementioned Braille guiding block 3, the line segment connecting the origin of the X-axis and the Y-axis and the vertical component of the midpoint of the aforementioned Y-axis has an elevation angle when viewed from the aforementioned X-axis, and the vertical component of the midpoint of the aforementioned Y-axis and the end point of the aforementioned Y-axis return to the original aforementioned XY plane at the uneven portion that a person touches on the aforementioned Braille guiding block 3, creating a protruding step on the aforementioned XY plane at the uneven portion that a person touches on the aforementioned Braille guiding block 3, and arranging it so that water flows to the lowest step of the uneven portion that a person touches on the aforementioned Braille guiding block 3 (Fig. 4).

[0017] Regarding the vertical and horizontal dimensions of a general Braille guiding block, the difference in steps of the uneven portion that a person touches on the aforementioned Braille guiding block 1 or the difference in steps of the uneven portion that a person touches on the aforementioned Braille guiding block 3 is about 5 mm to about 8 mm, which can be recognized as an obvious slope by visually impaired persons without disturbing normal persons, but is not a step that can catch the feet of normal persons and cause them to fall.

[0018] Since the functions of Fig. 3 and Fig. 4 are the same, for the sake of simplicity of explanation, Fig. 3 will be taken as an example for explanation.

[0019] The structural material 2 other than the aforementioned Braille guiding block 1 is generally composed of asphalt or cement or stone paving or resin, and in some cases, it is composed of a permeable paving material such as JIS A-1218.

[0020] Due to its nature, water flows from a higher level to a lower level. Therefore, even if the uneven portions that a person touches on the surface of the aforementioned braille guiding block 1 are wet with rainwater, the rainwater will flow to the portion with the lowest step of the uneven portions that a person touches on the aforementioned braille guiding block 1.

[0021] The rainwater that has flowed through the portion with the lowest step of the uneven portions that a person touches on the aforementioned braille guiding block 1 is discharged into the sewage directly or together with other sewage at one or more locations.

[0022] Even during rain or snowfall, since rainwater flows through the portion with a lower step of the uneven portions that a person touches on the aforementioned braille guiding block 1, the portion with a higher step of the uneven portions that a person touches on the aforementioned braille guiding block 1 will not form a water pool. Also, even when the rain or snow stops and only the wet ground or water pool remains, the rainwater will flow through the portion with a lower step of the uneven portions that a person touches on the aforementioned braille guiding block 1, and the portion with a higher step of the uneven portions that a person touches on the aforementioned braille guiding block 1 will quickly drain and dry.

[0023] Visually impaired persons who rely on the walking path on the aforementioned braille guiding block 1 of the present invention are guided by the aforementioned braille guiding block 1 to a place where there is less splashing of rain, snow, and shoes in rainy or snowy weather, and after the rain or snow has stopped, they are guided to a place where the ground has quickly drained and the feet are dry due to the step of the uneven portions that a person touches on the aforementioned braille guiding block 1.

[0024] In the intersection, there is no installation of braille guiding blocks because reasons such as improving the riding comfort of vehicles, being concerned about the noise between the tires and the road surface in nearby houses, or the unevenness in the intersection disappearing over the years and new unevenness having to be created in the intersection.

[0025] For visually and hearing-impaired people, although there are Braille guiding blocks up to the intersection, once they enter the intersection, the Braille guiding blocks disappear, which is very dangerous. However, in the aforementioned Braille guiding block 1 of the present invention, as long as the corresponding road surface is not in a bad condition, healthy people can clearly distinguish the aforementioned concave part of the Braille guiding block 1 from the road step. Therefore, the aforementioned concave part of the Braille guiding block 1 is also arranged in the part where the vehicle passes. The riding comfort does not change much, or the noise between the tire and the road surface does not occur, or the unevenness once created can be maintained. Moreover, the visually and hearing-impaired people can be guided by the aforementioned Braille guiding block 1 to ensure their safety.

Embodiment

[0026] In the Braille guiding block 5 that constitutes the yellow line indicating a safe section when passengers wait for a train or a train on the platform, taking the uneven part that people contact of the aforementioned Braille guiding block 5 as the XY plane, in the aforementioned uneven part that people contact of the aforementioned XY plane of the aforementioned Braille guiding block 5, the line segment connecting the starting points of the X-axis and the Y-axis and the vertical component of the midpoint of the aforementioned Y-axis has a depression angle when viewed from the aforementioned X-axis. When returning to the original aforementioned XY plane at the aforementioned uneven part that people contact of the aforementioned Braille guiding block 5 at the vertical component of the midpoint of the aforementioned Y-axis and the end point of the aforementioned Y-axis at the aforementioned uneven part that people contact of the aforementioned Braille guiding block 5, a concave step in the aforementioned XY plane is created. The lowest step of the aforementioned uneven part that people contact of the aforementioned Braille guiding block 5 is arranged so that water can flow (Figure 5).

[0027] In the braille guide block 8 that constitutes a yellow line indicating a safe section when passengers wait for a train or a train on the platform, the uneven portion that a person of the braille guide block 8 touches is set as the XY plane. In the uneven portion that a person of the braille guide block 8 touches on the XY plane, a line segment connecting the origin of the X-axis and the Y-axis and the vertical component of the midpoint of the Y-axis has an elevation angle when viewed from the X-axis, and the vertical component of the midpoint of the Y-axis and the end point of the Y-axis return to the original XY plane at the uneven portion that a person of the braille guide block 8 touches, creating a convex step in the XY plane at the uneven portion that a person of the braille guide block 8 touches, and arranging it so that water flows to the lowest step of the uneven portion that a person of the braille guide block 8 touches (Fig. 6).

[0028] Regarding the vertical and horizontal dimensions of a general braille guide block, the difference in steps of the uneven portion that a person of the braille guide block 5 touches or the difference in steps of the uneven portion that a person of the braille guide block 8 touches is about 5 mm to about 8 mm, which can be recognized as an obvious slope by visually impaired persons without disturbing normal persons, but it is not a step that can catch the feet of normal persons and cause them to fall.

[0029] Since the functions of Fig. 5 and Fig. 6 are the same, for the sake of simplicity of explanation, Fig. 5 will be taken as an example for explanation.

[0030] The structural material 6 other than the braille guide block 5 is generally composed of asphalt, cement, stone paving, or resin, and in some cases, it is composed of JIS A-1218, etc., which is a permeable paving material.

[0031] Due to the nature of water, it flows from a place with a higher step to a place with a lower step. Therefore, even if the uneven portion that a person touches on the surface of the braille guide block 5 is wet with rainwater, the rainwater will flow to the portion with the lowest step of the uneven portion that a person touches on the braille guide block 5.

[0032] The rainwater that has flowed through the lowest part of the uneven portion that the aforementioned person touches on the aforementioned Braille guiding block 5 is drained into the sewage directly or together with other sewage at one or more locations.

[0033] Recently, platform doors have begun to become popular on platforms. However, there are still many stations without platform doors, and at some stations, the white lines remain and there are places that have not become yellow lines. On such platforms with remaining white lines, a virtual yellow line is created inside a single white line. Taking the uneven portion that a person touches on the Braille guiding block 1' as the XY plane, at the uneven portion that the aforementioned person touches on the aforementioned XY plane of the aforementioned Braille guiding block 1', the line segment connecting the starting points of the X-axis and Y-axis and the vertical component of the midpoint of the aforementioned Y-axis has a depression angle when viewed from the aforementioned X-axis. When returning to the original aforementioned XY plane at the uneven portion that the aforementioned person touches on the aforementioned Braille guiding block 1' at the vertical component of the midpoint of the aforementioned Y-axis and the end point of the aforementioned Y-axis at the uneven portion that the aforementioned person touches on the aforementioned Braille guiding block 1', a sunken step on the aforementioned XY plane is created. By arranging it so that water flows to the lowest step of the uneven portion that the aforementioned person touches on the aforementioned Braille guiding block 1', it serves as a substitute for the yellow line.

[0034] Platforms include island platforms and opposed platforms. An island platform is a platform type where incoming trains or trains and outgoing trains or trains arrive separately at one platform building. In an opposed platform, incoming trains or trains and outgoing trains or trains arrive at different platform buildings. However, since an island platform only connects the sides where there are no trains or trains on the opposed platform, when only looking at the boarding areas for trains or trains, the island platform and the opposed platform are the same.

[0035] Due to its structure, the cross-section of the platform is such that the height from the ground of the platform is higher at places far from the train or train, and lower at places close to the train or train.

[0036] For normal people, on rainy or snowy days, it is part of the measures to prevent troubles among passengers, such as preventing rainwater from entering the train or causing trouble among passengers if clothes get wet and enter the train. However, for visually impaired people, they may not notice when a train approaches on the platform and may even be hit by the train in the worst case, and many such accidents have occurred.

[0037] If a visually impaired person pays attention to the approach of a train and stands far from the train in the middle of the platform as described above, when the train arrives, they cannot keep up with the flow of passengers getting on and off the train, and as a result, they cannot board the train or will miss the train.

[0038] When using the above-mentioned braille guiding block 5 of the present invention, the braille guiding block 5 at the feet clearly indicates the places that are not the places to walk, and it is very difficult to take off the above-mentioned braille guiding block 5 unless it is extremely difficult because one walks by sandwiching the above-mentioned braille guiding block 5 with both feet. Even if leading a guide dog, the guide dog will not be afraid of or scared of the above-mentioned braille guiding block and can walk normally.

Example

[0039] Taking the uneven part that a person touches of the braille guiding block 11 as the XY plane, in the uneven part that a person touches of the XY plane of the above-mentioned braille guiding block 11, the line segment connecting the starting points of the X-axis and Y-axis and the vertical component of the midpoint of the above-mentioned Y-axis has a depression angle when viewed from the above-mentioned X-axis, and the vertical component of the midpoint of the above-mentioned Y-axis and the end point of the above-mentioned Y-axis return to the original above-mentioned XY plane at the uneven part that a person touches of the above-mentioned braille guiding block 11, creating a concave step in the above-mentioned XY plane at the uneven part that a person touches of the above-mentioned braille guiding block 11, and a drain groove 13 is provided at the lowest step of the uneven part that a person touches of the above-mentioned braille guiding block 11 (Figure 7).

[0040] Taking the uneven portion that a person touches on the braille guiding block 14 as the XY plane, in the uneven portion that a person touches on the XY plane of the aforementioned braille guiding block 14, the line segment connecting the origin of the X-axis and the Y-axis and the vertical component of the midpoint of the aforementioned Y-axis has an elevation angle when viewed from the aforementioned X-axis, and the vertical component of the aforementioned midpoint of the aforementioned Y-axis and the end point of the aforementioned Y-axis return to the original aforementioned XY plane at the uneven portion that a person touches on the aforementioned braille guiding block 14, creating a convex step in the aforementioned XY plane at the uneven portion that a person touches on the aforementioned braille guiding block 14, and a drain groove 16 is provided at the lowest step of the uneven portion that a person touches on the aforementioned braille guiding block 14 (Fig. 8).

[0041] Fig. 7 is almost the same as Fig. 3 and Fig. 8 is almost the same as Fig. 4, but Figs. 7 and 8 are different from Figs. 3 and 4 in terms of the presence or absence of a drain groove. When the surface of the aforementioned braille guiding block 11 or the aforementioned braille guiding block 14 is wet with rainwater, the rainwater flows along the aforementioned braille guiding block 11 or the aforementioned braille guiding block 14 to the aforementioned drain groove 13 or the aforementioned drain groove 16. Since the other parts are the same, the common explanations for Figs. 3 and 4 are omitted, and only the explanations specific to Figs. 7 and 8 are given.

[0042] Although not shown in Figs. 7 and 8, there is no problem even if there is the aforementioned rainwater cover on the aforementioned drain groove 13 or the aforementioned drain groove 16. The aforementioned rainwater cover can prevent people from stepping into the small gap of the aforementioned drain groove 13 or the aforementioned drain groove 16 and getting injured, or prevent small objects from falling into the aforementioned drain groove 13 or the aforementioned drain groove 16 and falling into the sewage through the aforementioned rainwater cover. Therefore, it is better to have the aforementioned rainwater cover.

[0043] The aforementioned drain groove 16 has three types: a right-side drain groove, a left-side drain groove, and a both-sides drain groove. Here, the both-sides drain groove is taken as an example, but it is also okay to choose the aforementioned right-side drain groove or the aforementioned left-side drain groove due to construction reasons.

[0044] Since the functions of Figs. 7 and 8 are the same, for the sake of simplicity of explanation, Fig. 7 is taken as an example for explanation.

[0045] When rain or snow falls, the rainwater adhering to the aforementioned braille guiding block 11 is collected at the lowest stepped portion of the aforementioned braille guiding block 11. The rainwater collected by the aforementioned braille guiding block 11 flows into the aforementioned drain gutter 13, and the rainwater collected by the aforementioned drain gutter 13 is discharged into the sewer directly at one or more locations or together with other sewage.

[0046] When there is remaining snow in a cold region, if the reflectivity between the ground and the aforementioned drain gutter 13 is different, the snowmelt will progress significantly. When removing the snow accumulated on the road or sidewalk by a snowplow, it is also possible to utilize the water temperature of the aforementioned drain gutter 13 or the sewer to remove the snow.

[0047] When there is a lot of rain or snow, if there is the aforementioned rainwater cover on the aforementioned drain gutter 13, the fallen garbage can be dropped in front of the aforementioned rainwater cover in advance. However, there is also a problem that the aforementioned rainwater cover of the aforementioned drain gutter 13 may be accidentally removed. Therefore, usually the aforementioned rainwater cover of the aforementioned drain gutter 13 cannot be removed, but it is preferable to have a structure that allows the aforementioned rainwater cover to be easily removed during cleaning.

Embodiment

[0048] In the braille guiding block 17 that constitutes the yellow line indicating a safe section when passengers wait for a train or a train on the platform, the uneven portion that people contact on the aforementioned braille guiding block 17 is set as the XY plane. In the uneven portion that people contact on the aforementioned XY plane of the aforementioned braille guiding block 17, the line segment connecting the starting points of the X-axis and the Y-axis and the vertical component of the midpoint of the aforementioned Y-axis has a depression angle when viewed from the aforementioned X-axis. When returning to the original aforementioned XY plane at the uneven portion that people contact on the aforementioned braille guiding block 17 at the vertical component of the midpoint of the aforementioned Y-axis and the end point of the aforementioned Y-axis, a concave step in the aforementioned XY plane is created at the uneven portion that people contact on the aforementioned braille guiding block 17. A drain gutter 19 is provided at the lowest step of the uneven portion that people contact on the aforementioned braille guiding block 17 (Fig. 9).

[0049] In the braille guide block 21 that constitutes a yellow line indicating a safe section when passengers wait for a train or a train on the platform, the uneven portion that a person of the braille guide block 21 touches is taken as the XY plane. In the uneven portion that the person of the braille guide block 21 touches on the XY plane of the braille guide block 21, the line segment connecting the origin of the X-axis and the Y-axis and the vertical component of the midpoint of the Y-axis has an elevation angle when viewed from the X-axis, and the vertical component of the midpoint of the Y-axis and the end point of the Y-axis return to the original XY plane at the uneven portion that the person of the braille guide block 21 touches, creating a convex step in the XY plane at the uneven portion that the person of the braille guide block 21 touches. A drain 23 is provided at the lowest step of the uneven portion that the person of the braille guide block 21 touches (Fig. 10).

[0050] Fig. 9 is almost the same as Fig. 5 and Fig. 10 is almost the same as Fig. 6. However, Fig. 9 and Fig. 10 are different from Fig. 5 and Fig. 6 in terms of the presence or absence of a drain. When the surface of the braille guide block 17 or the braille guide block 21 is wet with rain, the rain flows along the braille guide block 17 or the braille guide block 21 into the drain 19 or the drain 23. Since the other parts are the same, the common explanations for Fig. 5 and Fig. 6 are omitted, and only the explanations specific to Fig. 9 and Fig. 10 are given.

[0051] Although not shown in Figs. 9 and 10, there is no problem even if there is a rain cover for the drain 19 or the drain 23. The rain cover can prevent people from stepping into the small gap of the drain 19 or the drain 23 and getting injured, or prevent small objects from falling into the drain 19 or the drain 23 and falling into the sewer. Therefore, it is better to have the rain cover.

[0052] In recent years, due to the no-smoking policy in the station building, there is no more littering of cigarette butts, and there is no cigarette butt garbage in the drain 19 or the drain 23. The garbage is mainly dry grass and fallen leaves, and a simple rain cover for the drain 19 or the drain 23 can handle it well.

[0053] The aforementioned drain 23 has three types: a right - hand drain, a left - hand drain, or a both - sides drain. Here, the both - sides drain is taken as an example. However, due to construction reasons, it is also okay to choose the aforementioned right - hand drain or the aforementioned left - hand drain.

[0054] Since the functions of FIGS. 9 and 10 are the same, for the sake of simplicity of explanation, FIG. 9 is taken as an example for explanation.

[0055] When it rains or snows, the rainwater on the aforementioned braille guiding block 17 is collected at the lowest - step part of the aforementioned braille guiding block 17. The rainwater collected by the aforementioned braille guiding block 17 flows into the aforementioned drain 19, and the rainwater collected by the aforementioned drain 19 is discharged into the sewer directly at one or more locations or together with other sewage.

[0056] On the platform, since passengers often drop things, it is preferable to provide the aforementioned rainwater cover for the aforementioned drain 19 or to have a structure that allows small items dropped into the aforementioned drain 19 to be easily picked up from the aforementioned drain 19.

[0057] If there is remaining snow in cold regions and the reflectivity between the ground and the aforementioned drain 19 is different, the snowmelt will progress significantly. When removing the snow accumulated on the track or platform by a Russell car or a snow - removal vehicle, it is also good to use the water temperature of the aforementioned drain 19 or the sewer to remove the snow.

[0058] When there is a lot of rain or snow, if there is the aforementioned rainwater cover for the aforementioned drain 19, the garbage that has fallen can be dropped in front of the aforementioned rainwater cover in advance. However, there is also a problem that the aforementioned rainwater cover of the aforementioned drain 19 may be accidentally removed. Therefore, usually the aforementioned rainwater cover of the aforementioned drain 19 cannot be removed, but it is good to have a structure that allows the aforementioned rainwater cover to be easily removed during cleaning.

[0059] The path for visually impaired people is not always a single one. When the above-mentioned braille guiding blocks of the present invention are divided in two directions, one way to guide the visually impaired is to use the above-mentioned braille guiding blocks with different patterns in the longitudinal and short-side directions of the above-mentioned braille guiding blocks.

[0060] It was assumed that the difference in steps of the uneven portions that the above-mentioned person contacts of the above-mentioned braille guiding blocks of the present invention is from about 5 mm to about 8 mm. However, the difference in steps of the uneven portions that the above-mentioned person contacts is only a guideline, and the difference in steps of the uneven portions that the above-mentioned person contacts of the above-mentioned braille guiding blocks may be lower or higher as long as the visually impaired can recognize it.

[0061] In the example, the above-mentioned concave portion or the above-mentioned convex portion of the uneven portions that the above-mentioned person contacts of the above-mentioned braille guiding blocks of the present invention was symmetric, but the above-mentioned concave portion or the above-mentioned convex portion of the uneven portions that the above-mentioned person contacts of the above-mentioned braille guiding blocks may be shifted to one side.

[0062] In the example, the above-mentioned concave portion or the above-mentioned convex portion of the uneven portions that the above-mentioned person contacts of the above-mentioned braille guiding blocks of the present invention was symmetric, but the heights of both ends of the uneven portions that the above-mentioned person contacts of the above-mentioned braille guiding blocks may be different.

[0063] In the example, the pattern of the above-mentioned concave portion or the above-mentioned convex portion of the uneven portions that the above-mentioned person contacts of the above-mentioned braille guiding blocks of the present invention was symmetric, but the pattern of the above-mentioned concave portion or the above-mentioned convex portion of the uneven portions that the above-mentioned person contacts of the above-mentioned braille guiding blocks may be different between the right half and the left half.

[0064] The above-mentioned concave portion or the above-mentioned convex portion of the uneven portions that the above-mentioned person contacts of the above-mentioned braille guiding blocks of the present invention may be in the shape of a bathtub curve when looking at the cross-section of the above-mentioned braille guiding blocks.

[0065] The above-mentioned concave portion or the above-mentioned convex portion of the uneven portions that the above-mentioned person contacts of the above-mentioned braille guiding blocks of the present invention does not need to be horizontal or vertical on each side.

[0066] The concave or convex portion of the uneven portion touched by the aforementioned person of the aforementioned Braille guiding block of the present invention does not have to be a straight line, and it may include a curve.

[0067] The cross-section of the aforementioned Braille guiding block of the present invention inevitably becomes an uneven cross-section, which causes problems during storage and installation of the aforementioned Braille guiding block. However, attaching a spacer that eliminates the step on the back surface of the aforementioned Braille guiding block is also one method.

[0068] For the purpose of explaining the aforementioned Braille guiding block of the present invention, an example of a single fold has been shown, but there are more folds, and there is no problem even if the steps gradually become lower or higher like a pyramid.

[0069] For example, in FIG. 3, a drainage channel or the like can be installed where it changes from the aforementioned structural material 2 to the aforementioned Braille guiding block of the present invention or from the aforementioned Braille guiding block of the present invention to the aforementioned structural material 2. However, since the influence on the function of the aforementioned drainage channel or the like is minor, it can be regarded as a part of many deformations.

Industrial Applicability

[0070] Although a sidewalk or a platform has been taken as an example, the Braille guiding block of the present invention applies to all general things. For example, it can be used in various places such as bus stops, taxi stands, tram stops, service areas, or parking areas.

[0071] Even when it rains or snows, visually impaired people can easily identify the center or both ends of the Braille guiding block of the present invention as easily as normal people, and there will be no resistance to walking outside, enabling them to enjoy work, recreation, and shopping, and fulfilling their role as a member of society even more.

[0072] Although an example has been given for explanation, those skilled in the art will easily understand that many deformations that do not substantially deviate from the novel matters and effects of the present invention are possible.
