  By the way, the conventional mat used on the braille block is often provided with a through-hole in a general mat in which the fiber layer is formed by flocking on the surface of the mat body. There was a problem that the appearance of the fiber deteriorated when a part of the fibers around the edge frayed.

  Accordingly, the present invention provides a mat capable of improving appearance in a form in which a mat is laid on a visually impaired person guidance block, a manufacturing method thereof, a visually impaired person guidance block, and a mat structure. For the purpose.

  The present invention that achieves the above-described object is a mat that is used by being laid on a block for guiding a visually impaired person having a plurality of protrusions on the surface of a flat block body, and a fiber layer is formed on the surface of the mat body. The mat body has a plurality of through holes formed at positions corresponding to the protrusions, and the fiber layer is formed to expose the surface of the mat body within a predetermined range from an edge of the through hole. It is characterized by.

  According to the mat configured as described above, since the fiber layer is formed so as to expose the surface of the mat body in a predetermined range from the edge of the through hole, a part of the fiber around the edge of the through hole is frayed. Therefore, the appearance of the mat itself can be improved. In addition, the said predetermined range can be 2-5 mm from the edge of a through-hole, for example.

  In the mat, the fiber layer is formed in a shape in which a plurality of dotted portions or a plurality of linear portions are opened so that a part of the surface of the mat body is exposed, and the mat body corresponding to the opening is formed. It can be manufactured by forming the through hole at a predetermined interval from the edge of the opening in the exposed portion.

  Further, the present invention is a block for guiding a visually impaired person having a plurality of protrusions on a surface of a flat block main body and using the mat on the protrusion, wherein the protrusion is provided with the mat. In the state, it has a lower part of the projection that fits in the through hole, and an upper part of the protrusion that overhangs from the lower part of the projection and that is applied to the exposed portion of the mat body.

  According to the visually impaired person guiding block configured as described above, since the upper part of the protrusion overhangs from the lower part of the protrusion, the upper part of the protrusion covers the periphery of the through hole, so that the appearance can be improved. Further, even when a foot or an object is hooked on the mat, the mat is hooked on the upper portion of the protrusion, so that the mat can be prevented from being displaced or detached from the visually impaired person guiding block.

  The present invention also provides a mat structure including a visually impaired person guidance block having a plurality of protrusions on a surface of a flat block main body and the mat laid on the visually impaired person guidance block. The protrusion has a lower part of the protrusion that fits in the through hole and an upper part of the protrusion that overhangs from the lower part of the protrusion and that is hooked on the exposed portion of the mat body when the mat is laid. The exposed portion is configured to be caught on the upper portion of the protrusion.

  According to the mat structure configured as described above, the upper portion of the protrusion overhangs from the lower portion of the protrusion and is hung on the exposed portion of the mat body, so that the upper portion of the protrusion covers the exposed portion and the appearance can be improved. Further, even if a foot or an object is hooked on the mat, the exposed portion of the mat body is hooked on the upper part of the protrusion, so that the mat can be prevented from being displaced or detached from the visually impaired person guiding block.

It is a disassembled perspective view of the mat structure which concerns on other embodiment of this invention. It is figure (a) and (b) which shows the other usage example of the mat | matte which concerns on embodiment of this invention.

Next, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.
As shown in FIG. 1, the mat structure 1 includes a Braille block 10 (block for guiding a visually impaired person) and a mat 20 that is used by being laid on the Braille block 10.

  The braille block 10 is configured to have a plurality of dot-like protrusions 12 arranged in a 5 × 5 lattice point pattern on the upper surface (front surface) of a flat (square) block main body 11. As shown in FIG. 2, the projection 12 includes a projection lower portion 13 and a projection upper portion 14.

  The protrusion lower portion 13 is a portion that fits into a through hole 23 described later in a state where the mat 20 is laid, and is formed in a columnar shape. The height (vertical dimension) of the protrusion lower portion 13 is substantially the same as the thickness of the mat body 21.

  The protrusion upper portion 14 is a portion that protrudes from the surface of the mat 20 (mat body 21) in a state where the mat 20 is laid, and alerts or warns a visually impaired person, and the outer peripheral surface faces from the bottom to the top. It is formed in a substantially truncated cone shape with a small diameter.

  The protrusion upper part 14 is formed so as to overhang from the protrusion lower part 13. Specifically, the protrusion upper portion 14 is formed so that the maximum diameter 14D is larger than the diameter 13D of the protrusion lower portion 13. Thereby, the protrusion upper part 14 is arrange | positioned so that it may hang | hang on the cyclic | annular exposed part 26 mentioned later of the mat 20 in the state by which the mat 20 was spread | laid.

  The mat 20 includes a mat body 21 and a fiber layer 22 formed on the surface of the mat body 21.

  The mat body 21 has a sheet shape and is made of an elastic material such as rubber. A plurality of through holes 23 into which the protrusions 12 (protrusion lower portions 13) are fitted are formed in the mat body 21 at positions corresponding to the protrusions 12 of the braille block 10 on which the mat 20 is laid. The mat body 21 has dimensions that are slightly larger (or substantially the same dimensions) than the braille block 10 in which the mat 20 is laid, and has a thickness of, for example, 2 to 10 mm. It has become.

  The fiber layer 22 is formed by planting fibers on the upper surface (surface) of the mat body 21. The fiber layer 22 is formed so as to expose the upper surface (front surface) of the mat body 21 with an interval R from the edge 23A of the through hole 23 (within a predetermined range). In other words, the fiber layer 22 has a plurality of (5 × 5 lattice point-like) circular shapes having a larger diameter than the through holes 23 of the mat body 21 at positions corresponding to the protrusions 12 of the Braille block 10 on which the mat 20 is laid. It is formed in a shape having an opening 24 (dotted portion). The space | interval R can be 2-5 mm from the edge 23A of the through-hole 23, for example. In addition, the formation method of the fiber layer 22 is not limited to flocking, A widely well-known method is employable.

Next, a method for manufacturing the mat 20 (mat structure 1) configured as described above will be described.
First, as shown in FIG. 3A, a sheet-like mat body 21 is prepared from a material having elasticity such as rubber by a known method.

  Next, as shown in FIG. 3B, the fiber layer 22 is formed in a shape (see FIG. 1) having 5 × 5 lattice point-like openings 24 so that a part of the surface of the mat body 21 is exposed. Form.

  Then, as shown in FIG. 3C, on the exposed surface 25 (exposed portion) of the mat body 21 corresponding to the opening 24, a through hole 23 is formed with a gap R from the edge 24A of the opening 24. The mat 20 can be manufactured.

  Further, as shown in FIG. 3D, the mat structure 1 can be configured by laying the mat 20 on the braille block 10 laid at the entrance of the building or the like. At this time, the annular exposed portion 26 (the exposed portion of the mat body 21 between the edge 23A of the through hole 23 and the edge 24A of the opening 24) is fitted so as to be hooked on the protrusion upper portion 14.

  When the mat 20 is laid on the braille block 10, the through hole 23 is expanded by the bending of the annular exposed portion 26 of the mat body 21 having elasticity by the protrusion upper portion 14. Then, after the protrusion upper portion 14 passes through the through hole 23, the protrusion lower portion 13 is fitted into the through hole 23 by returning the bending of the annular exposed portion 26 to the original state.

According to the above, the following effects can be obtained in the present embodiment.
The mat 20 of the mat structure 1 is formed so that the fiber layer 22 exposes the surface (annular exposed portion 26) of the mat main body 21 with a distance R from the edge 23A of the through hole 23. Thus, the fibers around the edge of the through hole are not frayed and pulled out. Therefore, the appearance of the mat 20 itself can be improved as compared with the conventional mat.

  In the braille block 10 of the mat structure 1, the protrusion upper portion 14 overhangs from the protrusion lower portion 13 and is hooked on the annular exposed portion 26, so that the annular exposed portion 26 can be covered (hidden) by the protrusion upper portion 14. Thereby, the appearance of the mat structure 1 can be improved. Further, even when a foot or an object is caught on the mat 20, the annular exposed portion 26 (mat body 21) is caught on the protrusion upper portion 14, so that displacement of the mat 20 and detachment from the braille block 10 can be suppressed.

  Since the mat body 21 is formed of an elastic material, the mat 20 can be laid relatively easily on the Braille block 10 and can be lifted from the Braille block 10 by lifting one side of the mat 20. It can be removed relatively easily. The detached mat 20 can be cleaned using a cleaning machine or the like, as in the conventional mat.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment. About a concrete structure, it can change suitably in the range which does not deviate from the meaning of this invention.

  In the said embodiment, although the example (mat structure 1) which combined and used the braille block 10 and the mat 20 was demonstrated, this invention is not limited to this. For example, the Braille block 10 and the mat 20 of the embodiment can be used in combination with a conventional mat and a conventional Braille block, respectively, and the following effects can be obtained.

  When the mat 20 of the embodiment and the conventional Braille block are used in combination, that is, when the mat 20 is laid on the conventional Braille block, the annular exposed portion 26 is exposed to the outside ( Visible). However, since the fibers around the annular exposed portion 26 are not frayed and pulled out, the appearance can be improved as compared with the case where a conventional mat is used. In this case, the interval R described above may be 2 mm or less.

  Further, when the Braille block 10 of the above embodiment and the conventional mat are used in combination, that is, when the conventional mat is laid on the Braille block 10, the upper portion 14 of the projection covers the periphery of the through hole. (Hide) can improve the appearance. Further, even when a foot or an object is hooked on the mat, the periphery of the through hole (mat body) is hooked on the protrusion upper portion 14, so that displacement of the mat and detachment from the braille block 10 can be suppressed.

  In the embodiment, the example in which the dotted projections 12 of the braille block 10 are arranged in a 5 × 5 lattice point shape is shown, but the present invention is not limited to this, and the number and arrangement of the dotted projections, etc. Can be appropriately changed.

  In the said embodiment, the mat structure 1 provided with the braille block 10 which has the some dotted | punctate protrusion 12, and the mat 20 which has the dotted | punctate (circular) through-hole 23 and opening 24 corresponding to the protrusion 12 was illustrated. However, the present invention is not limited to this. For example, like the mat structure 2 shown in FIG. 4, a Braille block 210 having a plurality of (four in FIG. 4) linear protrusions 212, a linear (rectangular) through-hole 223 corresponding to the protrusion 212, and It is good also as a structure provided with the mat | matte 220 which has the opening 224. FIG.

  The protrusion 212 is composed of a lower protrusion 213 and an upper protrusion 214 in the same manner as the protrusion 12. The protrusion lower portion 213 and the protrusion upper portion 214 are configured in substantially the same manner as the protrusion lower portion 13 and the protrusion upper portion 14 of the protrusion 12 described above, and thus description thereof is omitted. Further, the through hole 223 and the opening 224 are also configured in substantially the same manner as the through hole 23 and the opening 24 of the mat 20 described above, and thus description thereof is omitted.

  In the embodiment, the example in which the mat 20 is laid on the braille block 10 has been described, but the method of using the mat of the present invention is not limited to this. For example, as shown in FIGS. 5A and 5B, the braille scissors fixing tool 40 is inserted into the through hole 23 from the lower side of the mat 20, and the braille scissors 30 are inserted into the braille scissors fixing tool 40 from the upper side of the mat 20. It is possible to attach and use the mat 20 with protrusions.

  Here, the Braille heel 30 is composed of a heel body portion 31 that is a portion that alerts or warns a visually impaired person, and a leg portion 32 that extends downward from the center of the lower surface of the heel body portion 31. The maximum diameter of the heel body 31 is substantially the same as the diameter of the opening 24.

  Further, the Braille tack fixing tool 40 is formed in a substantially flange shape, and is provided in a substantially cylindrical fixing portion 41 to which the leg portion 32 of the Braille tack 30 is attached, and is provided at a lower portion of the fixing portion 41 and functions as a retainer. It is comprised from the disk shaped collar part 42. FIG. The fixing portion 41 has a height that is substantially the same as the thickness of the mat body 21, and a diameter that is substantially the same as the diameter of the through hole 23. The diameter of the flange 42 is larger than the diameter of the through hole 23.

  In the case where the mat 20 is used as shown in FIG. 5B, the radial length of the collar portion 42 is set so that the Braille rod 30 does not come out of the mat 20 together with the Braille rod fixing tool 40. For example, it is desirable to make it sufficiently large, for example, to be 5 mm or more, or to form the mat body 21 from a material harder than the above embodiment.
