Description

  The present invention relates to a walking path for guiding a visually impaired person to guide a visually impaired person in a road, a passage of a building, a vehicle, or the like.

  Conventionally, for visually impaired persons, a Braille block type is known in which a rugged pattern is provided on the surface of a walking path and the concavo-convex pattern is recognized by a visually impaired person by the sole of a foot or the tip of a cane. In recent years, a system has been proposed in which a barcode is attached to a flooring material, a code reader is attached to the tip of a white cane for a visually impaired person, and the code is read to guide and warn a visually impaired person (see Patent Document 1). In addition, a personal navigation system using a mobile phone, the Internet network or the like has been proposed (see Patent Document 2). Furthermore, a guidance system that recognizes a guidance line provided on a walking surface with a color sensor has also been proposed (see Patent Document 3).

  However, since the pattern of the above-mentioned patent document 1 uses a pattern such as a bar code, there is a risk of misidentification due to dirt adhesion, scratches, etc., which may lead to a serious accident. In addition, it is good to guide and warn patterns such as barcodes placed in front of stepped parts, branching points, etc. However, if they are continuously installed in the aisle, it will give a sense of discomfort to normal healthy people and relieve the sense of discomfort If the pattern is made smaller, the risk of misperception increases, and it is not suitable for a method of continuously guiding the visually impaired's walking.

  Regarding the thing of patent document 2, although the advantage which can obtain much information is large, these are also not suitable for the method of guide | inducing walking of a visually handicapped person continuously. In addition, the system becomes complicated and the frequency of malfunctions such as failures may increase, which is disadvantageous in terms of cost.

Regarding the thing of patent document 3, a visually impaired person's walk can be guide | induced continuously and it can implement at comparatively low cost. In recent years, however, outdoor pedestrian walkways have increased in color, and floor materials such as indoors and vehicles have many designs such as colors, and many respond to color sensors. Therefore, in order to avoid misidentification, the color of the induction line and the design of the flooring are greatly restricted.
Red, yellow, green, blue, white, black, and other pigments are usually used for the flooring. If the guide line is set to yellow, the flooring that appears green or beige at first glance is yellow. In many cases, pigments are used, and even if the yellow color of the induction line is identified by the color sensor, the color sensor responds anywhere on the flooring and cannot be induced. The same can be said for other color floors and induction lines. This problem is particularly serious when an induction line is provided on an existing flooring.

  The present invention has been made in view of the above-mentioned problems, and can be continuously guided and can be reliably guided by a visually handicapped person without any misrecognition of a color sensor without being greatly restricted by the design of a walking path. An object is to provide a walking path for guiding a visually impaired person who can walk to the front.

  The means of the present invention taken to solve the above problem is a walking path that guides a visually impaired person to a destination along a guidance line while identifying with a color sensor, and the guidance line does not misidentify with the color sensor. And a visually-impaired walking path for providing a masking portion on both sides or one side of the guide line.

  By using a walking path for guiding the visually impaired with a masking section near the guidance line, it is possible to prevent color sensors from misidentifying the color sensor due to the color of the walking path. You will be able to walk to the destination without fail.

  The walking path in this invention means asphalt pavement, concrete pavement, porcelain, concrete, rubber tiles, olefin, vinyl chloride, rubber, stone, wood, etc. Flooring.

  The guide line and the masking portion according to the present invention can be provided by attaching a film, a sheet or the like on the walking path or applying a paint or the like.

  The induction line according to the present invention can be set to a color tone such as red, orange, yellow, green, blue, purple, etc., as long as it is continuously connected in a line shape or intermittently in the longitudinal direction of the flooring. , Lines, broken lines, circles, polygons, other shapes, or combinations thereof. The width of the guide line is usually 10 to 300 mm, preferably 50 to 200 mm, more preferably 70 to 150 mm in consideration of the distinguishability and design properties of the color sensor.

  The masking unit according to the present invention needs to be set to a color tone different from that of the guide line so as not to be misidentified by the color sensor, and the use of the same colorant as that used for the guide line should be avoided. The width of the masking portion is usually 100 to 500 mm, preferably 150 to 400 mm, more preferably 200 to 300 mm in consideration of suppression of misidentification in the color sensor and design properties. The masking portions are provided on both sides of the guide line, but may be on one side as shown in FIG.

  The thickness of the guide line and the masking part is usually 0.03 to 2 mm depending on the part to be used, and 0.05 to 1.0 mm is preferable in view of durability and curling property during walking. -0.5 mm is more preferable.

When the guide line and the masking portion are provided by a film, a sheet, etc., the material of the film or sheet is not particularly limited, but synthetic resin, rubber, fiber, metal foil, or a composite thereof is preferable in terms of easy handling. Of these, olefin resins, vinyl chloride resins, fluorine resins, acrylic resins, polyamide resins, polyester resins, urethane resins, metal foils, or combinations thereof can be suitably used.
The guide line and the masking portion are obtained by giving a certain color tone or pattern to the film or sheet itself, or printing a certain color tone or pattern on the base of the film or sheet.

  In order to attach the film and sheet as the guide line and masking part to the walking path, it can be done by any method such as adhesive, adhesive, magnetic force, induction heating, thermal lamination, etc. Pasting is relatively easy. It is preferable to apply an adhesive to the guide line and the masking part film and the back of the sheet in advance so that it can be easily applied to a walking path. In order to prevent blistering due to air at the time of construction, it is necessary to give air permeability to the guide line and masking part film and sheet by needle hole processing etc., or to maintain the crossroads, adhesives and adhesives are mesh holes It is preferable to apply in the form of a mesh (a mesh is used as an air passage and only in the mesh), a dot or the like.

  When the guide line and masking part are provided by coating such as paint, inorganic, organic, or inorganic / organic mixed paints are used, and usually epoxy, polyester, and urethane paints are used. The

  The guide line may be formed by film or sheet bonding or paint coating, and the masking portion may be formed by paint coating or film or sheet bonding, and this combination is arbitrary. Further, the masking portion may be formed first, and the guide line may be formed thereon, and vice versa. Furthermore, it is also possible to integrally provide a guide line and a masking portion on the base of the film or sheet. The guide line and masking part can be formed by the above-mentioned methods, etc., but considering the workability, the masking part is formed first, and then the guide line is formed on the mask and the film and sheet base. A method of integrally providing the line and the masking portion is preferable.

  The masking unit may cover the entire width of the walking path except for the guide line as shown in FIG. 2, or may cover a part of the walking path only in the vicinity of the guide line as shown in FIG. In addition, in both cases where films, sheets, or paints are used for the guide lines and masking parts, UV curable paints, electron beam curable paints, etc. are provided on the surfaces of the guide lines and masking parts to improve wear resistance and scratch resistance. Surface treatment can also be performed with.

  The visually handicapped person should walk safely and safely along the guide line of the visually impaired person guide walking path of the present invention using a white cane with a color sensor described in Patent Document 3 described above. Will be able to.
