DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a home guiding block for a visually impaired person and a walking guideway for a visually impaired person, which are laid to guide a visually impaired person. To enable persons with disabilities to easily recognize the direction of the guidance destination and the direction of the safe area through the soles or white canes, especially for laying along the white line of the transportation station platform. The present invention relates to a suitable home guidance block for visually impaired persons and a walking guidance path for visually impaired persons.

[0002]

2. Description of the Related Art A home guidance block for the visually impaired (hereinafter simply referred to as a guidance block for simplicity) is also referred to as a guidance block for the visually impaired, and a conventional guidance block is shown in FIGS. ) Is a block provided with a plurality of parallel linear ridges on its surface as shown in FIG. 1), for displaying a guiding direction, for example, for displaying a direction to a place where a guiding target exists. used. As shown in FIGS. 8A and 8B, a position display warning block for the visually impaired (hereinafter, simply referred to as a warning block) has a spherical shape that forms a part of a sphere. It is a block with many projections scattered on its surface.For example, it is for the visually impaired that the location is the target location or that it should be stopped to check the safety of the surroundings. The purpose is to make them aware.

[0003] A visually impaired person can be safely guided by properly using a guidance block and a warning block according to their respective uses and purposes.
For example, as shown in FIG. 9, a conventional walking guideway for the visually impaired includes a plurality of guide blocks laid in a row with the longitudinal direction of the leading ridge directed in the guiding direction, and a change position of the guiding direction in a visual impairment. And a warning block to be recognized by the user, and is formed from the guiding end to the guiding destination.

[0004]

Problems of Home Guidance Block for the Visually Handicapped By the way, in the conventional guidance block, the upper surface of FIG.
As shown in (a) and (b), a plurality of linear ridges having the same width over the entire length and having the same shape at opposite ends are simply arranged in parallel with each other. It is just that. Therefore, the conventional guide block can give only information to the visually impaired that the guide destination is located on either side on the longitudinal extension of the linear ridge, and the guide destination is The visually impaired cannot give information such as whether it is in front of, behind, or on the right or left side of the guidance block. In other words, when the visually impaired reaches the guide block from the direction crossing the linear ridge, the visually impaired person should proceed, retreat, or go to the right even if the presence of the linear ridge can be recognized. I can't tell if I should or should go to the left. Therefore, in the conventional guidance block, the visually impaired, for example, when the visually impaired gets down on the platform of the station from the train, even if it can recognize the presence of the guidance block, to reach the stairs It was impossible to determine at all in the longitudinal direction of the linear ridge, and the visually impaired people often got stuck there.

[0005] The present inventor, based on various experiences encountered by himself being a visually impaired person, has taken the form of Japanese Utility Model No. 7-543.
As disclosed in No. 30, by providing a right triangular three-dimensional mark having an outline recognizable by a tactile sensation such as a white stick at the tip of the linear ridge, a traveling direction and a safe area for a visually impaired person are provided. It is devised to give guidance information on the direction of existence. FIGS. 6A, 6B, and 6C are respectively a perspective view, a plan view, and an arrow I of the guide block of the embodiment described in Japanese Utility Model Publication No. 7-54330.
It is a side view in -I. Guidance block 1 shown in FIG.
1 is a main block 12, four linear ridges 16 provided on the upper surface 14 thereof, and a leading ridge 18 provided at the tip of the linear ridge 16 to allow the visually impaired person to recognize the guiding direction V. Consists of

As shown in FIG. 6 (b), the leading ridge 18 is formed as a triangular ridge having a plane of a right triangle when viewed in a plane parallel to the upper surface 14 of the main body block 12. That is, it is located at a position closest to the guidance destination and protrudes toward the guidance destination, and is located on an extension of the right side edge 20 of the linear ridge 16 with respect to the guidance direction V of the linear ridge 16. A leading ridge is provided by a triangular ridge having a first triangular ridge 24 having one side and a second triangular ridge 26 projecting from the left side edge 22 of the linear ridge 16 in a direction perpendicular to the guiding direction V. 18 are constituted. The projection length l 'of the second triangular projection 26 is 20 mm.

When the white cane is slid along the left side edge 22 of the linear protrusion 16, the second triangular projection 26 prevents the white cane from sliding forward. If the promise or regulation that the projecting direction of the second triangular projecting portion 26 is safe is predetermined between visually impaired persons, the visually impaired person
It can be recognized that the left side of 1 is safe.

Problems of Position Display Warning Block for the Visually Impaired When the visually impaired person is walking on uneven ground or pavement, the tactile sensation of the sole becomes dull and the irregularity cannot be recognized. He couldn't stop because he recognized that he was going too far or lost his direction.

Problems of Walking Guideway for the Visually Impaired The conventional walking guideway for the visually impaired, in which guide blocks are arranged, has a linear shape even if the visually impaired can recognize the direction of the destination by the linear ridge. No information can be given to the visually impaired whether the direction across the ridge is safe. Therefore, even if the conventional guide block is laid along the white line of the platform of the station, it cannot be determined which side of the linear ridge is the dangerous railway side.
For this reason, the visually impaired has no choice but to follow only on the guide block, and must follow the guide block in a psychological state that is extremely uneasy for the visually impaired. As a result, an accidental fall from the platform onto the track sometimes occurred. In addition, in a conventional walking guideway for the visually impaired in which a guiding block and a warning block are combined, when a visually impaired person is walking on the guiding block while checking a linear convex portion, the touch received by the sole of the foot is reduced. The sensation becomes dull, and as a result, even when the robot reaches the warning block, it cannot be distinguished from the guidance block and often passes the warning block.

In view of the circumstances described above, an object of the present invention is to provide a home guidance block for visually impaired persons with better inductive properties, a stop warning block for visually impaired persons with high recognizability, and more secure guidance. It is an object of the present invention to provide a walking guideway for visually impaired persons.

[0011]

According to the present invention SUMMARY OF] for the visually impaired home guide block inventor has first below, it focuses on the second point.
The first is the instinct of the visually impaired. A visually impaired person walks while judging safety by relying on hearing and tactile sensation, particularly tactile sensation, so that the tactile sensation is usually more developed and sensitive than ordinary people. For this reason, the inclination direction can be easily determined if the taxiway has a slight slope. Further, when walking on the ground, a visually impaired person has an instinctual fear of intruding into a dangerous place such as a groove when walking in a direction of decreasing height. On the other hand, when walking in a slightly higher direction, they instinctively recognize that they are safe. The second is a position where the visually impaired person walks with respect to the conventional guide block. In the conventional guide block, the distance between the linear ridge and the adjacent linear ridge is too small, so that when a visually impaired person walks following the guide block, the outermost portion formed on the periphery of the linear ridge is It is difficult to recognize the steps other than the steps 10A and 10B by the tactile sensation of the sole. For this reason, the visually impaired person needs to walk while checking the guidance direction so that the sole hits the step 10A or 10B, and walks on the right end or left end of the guidance block. Therefore, the present inventor has as a result of intensive studies, as a result, the top surface has an inclined surface that rises toward the guidance destination, and furthermore, the distance between the linear ridge and the adjacent linear ridge is made larger than before. We devised a guide block that is slightly wider and allows any step on the linear ridge to be recognized by the tactile sensation of the sole.

In order to achieve the above object, a home guidance block for a visually impaired person according to the present invention (hereinafter, referred to as a first invention) is provided to guide a visually impaired person to walk toward a guidance destination. This is a home guidance block for the visually impaired provided with a plurality of linear ridges extending almost parallel to the upper surface. The visually impaired person follows the linear ridges through a shoe sole or a white cane, etc. The guiding block is designed to guide the walking of the subject, and the linear ridge is located 5 mm from the upper surface of the block.
mm, with a top surface that is gently inclined upward toward the guidance destination in an angle range of 0.3 ° to 1.0 ° with respect to a horizontal line, and has a top surface that is protruded up and down around 20 mm and a width of 20 mm to 25 mm, and At the end of each of the linear ridges near the guidance destination, there is provided a leading ridge having a right triangular top surface formed at the same height on the upper surface of the linear ridge, and a linear ridge is provided. The distance between the bottom edge of the ridge and the bottom edge of the adjacent linear ridge is 40 mm to 7
0 mm, the top surface of the right triangular shape of the leading ridge is such that the first acute triangle is located at the tip closest to the guidance destination and the second acute triangle is the top surface of the linear ridge. Projecting outward from a side edge in the width direction at least about 20 mm to about 30 mm in a direction substantially orthogonal to the side edge, and a side corresponding to the second acute triangular portion is formed on the top surface of the linear protrusion. The side surface of the linear ridge and the leading ridge is formed so as to coincide with the extension of the other side edge from the periphery of the top surface by 45 ° to 6 °.
It is formed to reach the upper surface of the block at an angle (α) in the range of 0 °, with the first acute triangle of the leading ridge pointing toward the guidance destination and the second acute triangle being safe. It is characterized by designating an appropriate area. Preferably, the guidance destination is a stair.

The reason why the width of the linear protruding portion is set to a band shape in the range of 20 mm to 25 mm is that if the width is 20 mm or less, it is difficult to recognize the inclined surface with the tactile sensation of the shoe sole, and if it is 25 mm or more, the shoe sole has a line. This is because the linear ridge may not be recognized due to insufficient contact with the step of the ridge. The distance between the bottom edge of the linear ridge and the bottom edge of the adjacent linear ridge is in the range of 40 mm to 70 mm. This is because it is difficult to recognize the step difference of 70 mm or more, and if it is 70 mm or more, the shoe sole does not sufficiently hit the step of the linear protrusion, and the inclination direction of the linear protrusion may not be recognized. It is not more than 20 mm that the second acute triangular portion of the leading protrusion projects at least 20 mm or more outwardly in a direction substantially perpendicular to the side edge from one widthwise edge of the top surface of the linear protrusion. If there is, it is difficult to recognize it with a white cane or the like. Further, the angle formed between the top surface of the linear ridge and the horizontal line is in the range of 0.3 ° to 1.0 °, and the angle (α, α) formed between the side surface of the linear ridge and the leading ridge and the top surface.
(See FIG. 2 (c)) in the range of 45 ° to 60 °
If the angle is less than the angle, it is difficult to detect the shoe sole, and if the angle is more than that, ordinary pedestrians are likely to stumble and be dangerous. In the first invention, since the top surface of the linear ridge rises and inclines in the guiding direction, the direction in which the visually impaired instinctively walks matches the guiding direction. In addition, even when walking on the guide block, all steps along the guide direction of the periphery of the linear ridge can be recognized by the tactile sensation of the shoe sole, so that the user can walk on the guide block with confidence in the guide direction.

[0014] The stop warning block for the visually impaired person according to the present invention.
Click Further, the present inventor has also dulled senses tactile receive the sole walks over the guide block, so that it can recognize that the sole reaches the warning block, the central portion of the warning projecting block Various experiments were conducted with the idea that the height position of the portion was higher than the surrounding protrusions. As a result of the experiment, ordinary pedestrians tripped when the center of the guide block was too high. Also, if only the central projection is raised,
Only the protrusions were worn, which was not good in durability.
Then, the present inventor tried to make the central portion of the warning block appropriately higher than the peripheral edge, and completed the present invention separately from the first invention.

A stop warning block for the visually impaired according to the present invention (hereinafter, referred to as a second invention) has a plurality of truncated cone-shaped projections arranged on an upper surface so that a visually impaired person can recognize a stop position. A stop warning block for a disabled person, wherein the upper surface of the block has a similar shape with a smaller size than the periphery of the block, a horizontal distance from the periphery of the block is in a range of 9 cm to 12 cm, and a range of 5 mm to 10 mm. A horizontal center plane having a height higher than the upper side of the block periphery, and an angle (β) in the range of 2 ° to 7 ° with respect to the horizontal plane from the center plane periphery.
And an inclined plane descending to the periphery of the block, and at least one projection is formed on the central plane. The position of the central plane is a distance range of 9 cm to 12 cm from the periphery of the block, the central plane is at least 5 mm higher than the periphery of the block, and the angle between the inclined plane and the horizontal plane is 2 ° or more. This is so that the guidance block and the warning block can be clearly distinguished even in the sole where the tactile sensation has become dull. Also, the central plane is higher than the block periphery by a height difference of 10 mm or less,
The angle between the inclined plane and the horizontal plane was 7 ° or less.
This is to prevent general pedestrians from tripping.

In the first invention and the second invention, the shape of the block is not limited to a flat plate or a quadrangular prism block having a relatively large dimension in the thickness direction, that is, a thick block. It may be a thin plate having a relatively small thickness. Such a block may be laid directly on the platform of the station depending on its thickness, or may be attached to an existing walking surface with an adhesive or the like. The material for forming the block is not particularly limited, and concrete, cement mortar, plastic, and the like can be used. However, concrete is preferable in order to prevent the upper surface of the block from becoming slippery when wet by rain or the like. According to the second invention, a stop warning block for the visually impaired with high recognizability is realized.

In the walking guideway for the visually impaired person according to the present invention, the walking guideway for the visually impaired person according to the present invention (hereinafter referred to as a third invention) has a first acute-angled triangular portion directed to a guidance destination. A plurality of home guidance blocks for the visually impaired person according to the first invention laid in a line in the traveling direction, with the directions of the second acute triangles aligned, and the visually impaired person according to the second invention laid at the stop position It is equipped with a stop warning block for use. The guidance destination is preferably a staircase. According to the third aspect of the present invention, since a guide path in which a guide block having a height difference formed on the upper surface and a warning block are formed is formed, it is complex to recognize the traveling direction and the stop position with the tactile sensation of the sole. The effect occurs. For example, even if a visually impaired person walks on the home guidance block for the visually impaired and the tactile sensation received by the sole becomes dull, the tactile sensation of the sole indicates that the person has reached the stop warning block for the visually impaired. It is clearly recognizable, is prevented from passing through the stop warning block for the visually impaired, and the visually impaired can reliably reach the guidance destination. In addition, since the direction of the safety zone is indicated by the second acute triangle, the driver recognizes which of the right and left directions is safe, and can easily change the traveling direction on the warning block.

The home guidance block 30 for the visually impaired person of the present embodiment (hereinafter, abbreviated as the guidance block 30 for simplicity) includes a main body block 32, a linear protrusion 36 provided on an upper surface 34 thereof,
And a leading ridge 38 provided at the tip of the linear ridge 36.

The main body block 32 is set to an appropriate thickness depending on whether it is a thick block laid directly on a roadbed or a thin plate block stuck on an existing walking surface, and has a side of 30 cm (S1 and S2). The upper surface 34 has four linear protrusions 36 extending parallel to each other in the direction V for guiding the visually impaired. The linear ridges 36 are arranged on the upper surface 34 at substantially equal intervals, and have a leading ridge 38 at the tip thereof in the guiding direction V. The other end 40 located on the side facing the leading ridge 38 is configured to have an outer convexly curved periphery.

In this embodiment, the leading ridge 38 provided at the leading end of the linear ridge 36 in the guiding direction is viewed in a plane parallel to the upper surface 34 of the main body block 32 as shown in FIG. It is formed as a triangular ridge having a plane of a right triangle. That is, it is located at a position closest to the guidance purpose and projects so as to direct the guidance purpose, and one side of the linear projection 36 extends along an extension of the right side edge 20 of the linear projection 36 with respect to the guidance direction V. And a second triangular protrusion 46 projecting from the left side edge 22 of the linear protrusion 36 in a direction perpendicular to the guiding direction V. 38 are configured.

As shown in FIG. 2B, the top surface of the linear ridge 36 is oriented in the direction V with respect to the upper surface 34 of the main body block 32.
The height of the top surface of the linear ridge 36 is h ₁ = 2 mm at the end 40 and h ₂ = 5 mm at the opposing tip end 45. As shown in FIG. 2 (c), the cross-sectional shape of the linear protrusion 36 is inclined outward at an angle of α = 45 ° from the top surface so that the upper surface 3

Embodiment of Walking Guideway for the Visually Impaired This embodiment combines the guide blocks 30 and 48 of the first embodiment with the warning block 50 of the second embodiment, and provides two steps for general passengers. It is an embodiment of the third invention in which a walking guideway for the visually impaired (hereinafter, abbreviated as a guideway) is formed on a platform of a station provided at the station. FIG.
FIG. 2 is a plan view illustrating the concept of a guideway according to the present embodiment. The taxiways of the present embodiment are taxiways 64A to 64D to the first staircase 62A.
And the taxiways 64E to 64E to the second stairs 62B and the taxiway 6
Guide paths 66A and B are respectively connected to the tips of 4A to 4D and 64E to 64H.

The taxiway 64A extends from a predetermined position at an end in the longitudinal direction of the home to the right side wall 70a toward the stair 62A.
The guide blocks 30 are arranged in a row at a predetermined distance from A. In the leading protrusion 38 of each guide block of the guide path 64A, the second triangular protrusion 38
Protrudes to the left side of the linear ridge 36, that is, the safe side. The guide path 64B is configured by laying the guide block 48 on the home side wall 70B facing the home side wall 70A in the same manner as the guide path 64A. At the leading ridge of each guide block of the guide path 64B, the second triangular protrusion protrudes to the right side of the linear ridge, that is, on the safe side, similarly to the guide path 64A. Warning blocks 50A and 50B are laid at the tips of the guideways 64A and 64B, respectively. In addition, a conventional point display warning block 72 of 30 cm square, which makes a visually impaired person recognize the stairway entrance of the stairs, is laid side by side so as to connect the stairway entrance of the stairway 62A and the warning blocks 50A, 50B. The guideway 64C has a warning block 50A at its tip.
Stairs 6 so as to be connected to the side of
The guide blocks 30 are arranged in a line at a predetermined distance from the home side wall 70A on the left side toward 2A. The guideway 64D is configured by laying the guide block 48 on the home side wall 70B in the same manner as the guideway 64A.

The guideways 64E to 64H are laid toward the stairs 62B in the same manner as the guideways 64A to 64D.

The visually impaired can use the side wall 70A from the train.
When the vehicle descends in the vicinity, the taxiways 64A, C, and
Recognize and reach either F or H with a white cane. Taxiway 64
When the vehicle reaches A, the second triangular projection of the leading ridge 38 is clearly recognized by the tactile sensation of the white cane, the sole of the shoe, or the like.
It is possible to obtain information that it is dangerous to further deflect forward to the right of 4A. In addition, the visually impaired can recognize the inclination direction of the top surface of the linear protrusion 36 by the tactile sensation of the shoe sole, and can clearly determine the guiding direction. Even when the vehicle reaches one of the guideways 64C, F, and H, the guide direction can be similarly clearly determined. When reaching the warning block 50A or 50B, the arrival is surely recognized by the tactile sensation of the sole, and then temporarily stopped. Since the visually impaired has already obtained the information that it is dangerous to further deflect to the right and move forward, it is presumed that the guiding direction will change to the left, and the elongated conventional warning block 72 is replaced with a white stick or a white stick. Recognizing with a tactile sensation such as a sole, the user reaches the stairs 62A or 62B and climbs. Home side wall 7 instead of near home side wall 70A
Similarly, when the vehicle descends near 0B, the stairs 62A
Or reach 62B and ascend.

In the present embodiment, the visually impaired person, through the sole of the shoe, connects the stairway entrance of the stairs 62A and 62B as the guidance destination and the direction in which the safe area in the platform opposite to the track exists. The user can clearly recognize and walk with the tactile sensation of the sole. Further, even if the tactile sensation received by the sole becomes dull due to the steps while walking the guide blocks 30 and 48, it is possible to reliably recognize the arrival on the warning blocks 50A and 50B by the tactile sensation of the sole. Change the direction of travel,
It is possible to reliably reach the stairs 62A or 62B and further to the guidance destination.

When the guiding block 30 of the present embodiment was prototyped and subjected to an experiment with a blind person, 48 out of 50 persons could clearly recognize the traveling direction of the guiding block on the guiding path 64,
In addition, the traveling direction is easily changed by clearly recognizing that the traveling direction changes when the warning block 50 is reached.

[0035]

According to the first aspect of the present invention, the linear protrusion of the home guidance block for the visually impaired protrudes about 5 mm from the upper surface of the block, and the top is gently inclined upward toward the guidance destination. At the end of each linear ridge near the guidance destination, a leading ridge having a right triangular top surface is provided, at least so as to be orthogonal to one side edge of the leading ridge. The distance between the linear ridge and the adjacent linear ridge protruding from 20 mm to 30 mm is in the range of 40 mm to 70 mm. Thereby, the visually impaired can clearly recognize the traveling direction to the guidance destination by the tactile sensation of the sole via the sole, and can clearly recognize the safe area by the tactile sensation such as the white cane or the sole. . In addition, since the distance between the linear ridge and the adjacent linear ridge is wider than before, when walking on the guide block, the step of the linear ridge can be reliably recognized by the tactile sensation of the sole, and the traveling direction can be determined. There is a combined effect of being clearly recognizable.

Further, according to the second aspect of the present invention, the upper surface of the stop warning block for the visually impaired has a similar shape smaller in size than the block periphery, and has a higher height position than the upper side of the block periphery. It is composed of a central plane and an inclined plane in which the peripheral edge of the block is lowered from the peripheral edge of the central plane, and at least one projection is formed on the central plane. Thereby, a stop warning block for visually impaired persons with high recognizability can be realized, and the visually impaired person can clearly recognize that the touch panel has reached the warning block even if the tactile sensation received by the sole becomes dull.

Further, according to the third aspect of the present invention, in the walking guideway for the visually impaired, the first acute triangle points in the traveling direction to the guidance destination, and the direction of the second acute triangle points. There are a plurality of guide blocks of the first invention laid in a line in a row, and a warning block of the second invention laid at a stop position. As a result, a guiding path is formed in which a guiding block having a height difference formed on the upper surface and a warning block are laid, so that a combined effect can be obtained by recognizing the traveling direction and the stopping position with the tactile sensation of the sole. is there. Therefore, a visually impaired person can clearly recognize the guidance destination and the direction in which the safe area exists by the tactile sensation of the sole via the sole, and walk when walking. In addition, the traveling direction can be easily changed on the warning block.
