  The block for guiding visually handicapped persons according to the present invention is provided with a phosphorescent layer (or a phosphorescent layer and a glass bead layer) only at the bottom, so that visually impaired persons with low vision can easily identify even at night, and the installation is large. Does not require any special equipment or construction. Moreover, durability is favorable. Moreover, the visually impaired person guidance block which has a luminous layer can be manufactured comparatively easily by using the formation sheet for visually impaired person guidance block formation which concerns on this invention. Moreover, the road surface display body according to the present invention is easy to identify even if it is not a visually handicapped person, and has good durability.

  Hereinafter, a visually impaired person guidance block according to a preferred embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a planar shape of a point-like visually impaired person guiding block according to a preferred embodiment of the present invention. This visually impaired person guiding block 1 has a rectangular bottom 10 and circular protrusions 11 protruding from the bottom 10 and arranged in a matrix. This visually impaired person guiding block 1 conforms to the current JIS standard, has an outer dimension of about 30 cm square, and has 5 × 5 protrusions 11 having a diameter of about 2.2 cm. .

  FIG. 2 is an enlarged sectional view showing the vicinity of the surface of the visually impaired person guiding block 1. The base body 12 is made of asphalt, concrete mortar, or the like, and has a bottom 10 on the surface side and a protrusion 11 that protrudes about 5 mm from the bottom 10 and is colored in a conspicuous color (for example, yellow). . A phosphorescent layer 14 is provided on the surface of the bottom 10 of the base body 12 via a glass bead layer 13. Further, a protective layer 15 is provided on the surface of the protrusion 11 of the base body 12 where the luminous layer 14 and the luminous layer 14 do not exist so as to cover them, and an anti-slip layer 16 is provided on the protective layer 15. ing.

  The glass bead layer 13 reflects in the direction of the light when illuminated at night, and together with the phosphorescent layer 14 makes it easy for visually impaired persons with low vision to identify the visually impaired person guiding block 1. In the glass bead layer 13, glass beads having a small particle size (for example, around 50 μm) are densely embedded on the surface of a colored (for example, white or silver) resin for holding the glass beads.

  The phosphorescent layer 14 accumulates light during the daytime and shines at night, thereby making it easier for visually impaired persons with low vision to identify the visually impaired person guiding block 1. The phosphorescent layer 14 contains phosphorescent pigments that store ultraviolet rays by absorbing them in a volume ratio of 10% to 30%. Others are transparent resins. In order to transmit light of light to the glass bead layer 13 described above, the luminous pigment is preferably about 10%.

  The protective layer 15 provided on the phosphorescent layer 14 protects the relatively flexible phosphorescent layer 14 to improve durability. Further, the protective layer 15 provided on the protrusion 11 of the base 12 suppresses the wear of the base 12 of the protrusion 11. The material of the protective layer 15 is preferably a hard acrylic resin. Hard acrylic resin has high chemical resistance and little discoloration over time. In addition, since the road surface and the atmosphere are cured by radical polymerization after application even at a low temperature (for example, below 30 ° C.), the construction is quick and the work can be completed at night. Further, the protective layer 15 is substantially transparent, and does not include a component that cuts ultraviolet rays such as an ultraviolet absorber for the luminous layer 14.

  The anti-slip layer 16 suppresses slipping of shoes or tires. The anti-slip layer 16 is provided with slight irregularities on the surface by sparsely arranging glass beads having a large particle size (for example, 1 mm) whose shape is not constant.

  As described above, the visually impaired person guiding block 1 is provided with the glass bead layer 13 and the phosphorescent layer 14, so that visually impaired persons with low vision can easily identify at night, and large-scale facilities and construction are required for installation. And not. Further, since the glass bead layer 13 and the phosphorescent layer 14 are provided only on the bottom portion 10, the weight of what passes over the visually impaired person guiding block 1 is not easily applied to the glass bead layer 13 and the phosphorescent layer 14. Is good.

FIG. 3 shows a planar shape of a point-like visually impaired person guidance block according to another preferred embodiment of the present invention. This visually impaired person guiding block 2 is a modification of the visually impaired person guiding block 1 and has an outer dimension of about 30 cm square and an array of 7 × 7 projections 11 having a diameter of about 2.2 cm. Has been. The gap between the adjacent projecting portions 11 and 11 is shortened in order to prevent the phosphorescent layer 14 from being directly damaged by what passes over the visually impaired person guiding block 2. The length of this interval (L _X or L _{Y in} FIG. 3) is preferably 2 cm or less in order to make it difficult to touch shoes or bicycle tires. The cross-sectional structure of the visually impaired person guiding block 2 is the same as that of the visually impaired person guiding block 1.

  As described above, the glass bead layer 13 and the phosphorescent layer 14 are provided only on the bottom 10. A method for manufacturing the visually impaired person guide blocks 1 and 2 for providing these will be described below. FIG. 4 shows a forming sheet for forming a visually impaired person guiding block, specifically, a forming sheet 40 for forming the glass bead layer 13 and the phosphorescent layer 14 of the visually impaired person guiding blocks 1 and 2. The forming sheet 40 has the glass bead layer 13 and the phosphorescent layer 14 on the release paper 41 via the adhesive layer 42. The glass bead layer 13 and the phosphorescent layer 14 have a plurality of hole portions 43 corresponding to the protrusions 11 in FIGS. 1 and 3, and these two layers have substantially the same planar shape. The formation sheet 40 is substantially the same size as the base body 12 of the visually impaired person guiding blocks 1 and 2. In order to manufacture the visually-impaired person guiding blocks 1 and 2 using the forming sheet 40, first, the forming sheet 40 is prepared, and the release paper 41 of the forming sheet 40 is removed. And the adhesion layer 42 is mounted in the bottom part 10 of the base body 12, and it pressurizes and adheres. Thereby, the glass bead layer 13 and the luminous layer 14 are provided only at the bottom 10. In order to increase the work efficiency, it is also possible to connect the forming sheets 40 continuously in a tape shape and simultaneously provide the glass bead layer 13 and the phosphorescent layer 14 on the plurality of visually impaired person guidance blocks 1 and 2. In this manufacturing method, the glass bead layer 13 and the phosphorescent layer 14 can be formed relatively easily in terms of work efficiency and cost. Note that the protective sheet 15 may be further provided on the forming sheet 40.

Next, a linear blind hand guiding block to which the present invention is applied will be described. FIG. 5 shows a planar shape of a linear blind hand guiding block according to a preferred embodiment of the present invention. This visually impaired person guidance block 3 has a rectangular bottom portion 30 and projecting portions 31 protruding from the bottom portion 30 and arranged in a line. This visually impaired person guiding block 3 has an outer dimension of about 30 cm square. And only six protrusions 31 having a width of about 2 cm are arranged. Further, there are a portion 30a where the gap between the adjacent protrusions 31, 31 is relatively wide and a portion 30b where the gap is relatively narrow. These points are different from the current JIS standard. The length L _X ′ of the relatively narrow portion 30b is the same length as the interval length L _X in the visually impaired person guiding block 2 of FIG. The cross-sectional structure of the visually impaired person guiding block 3 is the same as that of the visually impaired person guiding block 2.

  The visually-impaired person guiding block 3 is easy to identify visually impaired persons with low vision even at night, like the visually-impaired person guiding blocks 1 and 2, and does not require large-scale equipment or construction for installation. Moreover, the durability 30 is good and the portion 30b where the gap between the adjacent protrusions 31 and 31 is relatively narrow passes over the block 1 for guiding the visually impaired, so that the phosphorescent layer 14 may be directly damaged. It is suppressed.

  In addition, since the structure which consists of the order of the base body 12, the glass bead layer 13, the luminous layer 14, the protective layer 15, and the anti-slip layer 16 can be easily identified at night other than the visually impaired block, other road surfaces ( For example, the present invention can be applied to display bodies such as roads and heliports of general vehicles.

  The glass bead layer 13 is desirable for identifying the visually impaired person guiding blocks 1, 2, and 3, but may be omitted if the luminous layer 14 is sufficiently effective. In this case, the above-described forming sheet 40 is not provided with the glass bead layer 13.

  As described above, the visually impaired person guiding block according to the embodiment of the present invention has been described. However, the present invention is not limited to that described in the embodiment, and various modifications within the scope of the matters described in the claims. Design changes are possible. For example, the planar shape or the cross-sectional structure described in the embodiment can be deformed, and various improvements can be made in terms of sensitivity or discrimination.
