Description

  The present invention relates to a block for guiding a visually impaired person, and a protrusion forming body and a block body. More specifically, the present invention relates to a visually impaired person guidance block laid on a walking surface to guide a visually impaired person and assist walking, and a protrusion forming body and a block body used for the visually impaired person guidance block.

In order to guide a visually handicapped person, urge warning, and assist walking, laying a block for guiding a visually handicapped person having a linear or dotted protrusion on a walking surface is performed.
There is a method of laying a projection on the surface of the block as a block for guiding the visually impaired, and laying it on the walking surface, but a method of laying the projection directly on the walking surface without using such a block There is also.

The protrusion unit described in Patent Document 1 includes a pair of rod-shaped support bodies and one or more protrusion-forming bodies, and the protrusion formation body has one end portion connected to one of the pair of rod-shaped support bodies. In addition, the other end portion is connected to the other of the pair of rod-shaped supports, and is provided between the pair of rod-shaped supports in a bridging manner. Further, the projection forming body is configured such that the back surface thereof is an adhesive surface bonded to the walking surface with an adhesive, and the projection forming body and the rod-shaped support body can be separated at the connecting portion.
Thus, the protrusion unit is arranged on the walking surface with the bonding surface of the protrusion forming body facing down while holding the rod-shaped support, and by bonding the bonding surface to the walking surface with an adhesive, Can be easily fixed at a predetermined position on the walking surface. And after this fixation, a protrusion can be directly formed in a walking surface by separating a protrusion formation body and a rod-shaped support body in a connection part.

  However, since the protrusion unit described in Patent Document 1 simply adheres the back surface of the protrusion formation body to the walking surface with an adhesive, it is subject to a load caused by walking of a person, kicking with a shoe tip, There is a problem that it often peels off when you get in.

  In addition, the conventional visually-impaired person guidance block has the whole block made yellow. This is to improve the visibility of the visually-impaired person guiding block on the road surface such as gray asphalt for visually-impaired persons and healthy persons.

  However, as the range of action for visually impaired persons becomes wider, it is required that the visually impaired person guidance block be installed not only on the road surface such as asphalt but also indoors such as buildings. When indoors such as buildings, the walking surface may be colored by color tiles, etc., but when the yellow visually impaired guide block is laid on such a walking surface, the visibility is rather low There is also a problem that the scenery is impaired.

(First embodiment)
As shown in FIG. 1, the protrusion forming body A according to the first embodiment of the present invention has a bar shape in plan view, and a plurality of the protrusion forming bodies A are laid in parallel, and linear protrusions for instructing the moving direction and Is to do.
More specifically, the protrusion forming body A has a flat plate shape and has a long rectangular shape in plan view, and is defined in JIS T9251 (the shape and size of protrusions such as blocks for guiding the visually impaired and their arrangement). It has the dimension of a linear protrusion.

As shown in FIG. 2 (A), the protrusion forming body A is formed of a top plate 10 that comes into contact with the sole of the pedestrian and a foot portion 20 that hangs down from the long edge of the top plate 10, The cross-sectional shape is a gate shape. A pressure contact protrusion 21 extending linearly in the longitudinal direction is formed on the outer surface of the foot 20.
Further, a non-slip columnar protrusion 11 is formed on the surface of the top plate 10. As a result, when the protrusion forming body A is laid, friction with the shoe sole increases, thereby preventing slipping.
Further, as shown in FIG. 2 (C), a plurality of adhesive grooves 12 are formed vertically and horizontally on the back surface of the top plate 10.

As shown in FIG. 1 (A), the protrusion forming body A is divided into three short rod-shaped protrusion forming bodies 30 each having a length that is one third of the protrusion forming body A, and a short rod-shaped protrusion forming body at the center. 30 and the short rod-shaped protrusion forming bodies 30 at both ends thereof have a shape in which the ends are connected by a thin connecting portion 31.
More specifically, as shown in FIG. 2 (B), the connecting portion 31 connects the short rod-shaped protrusion forming bodies 30 to each other at the base portion of the foot portion 20 with the top plate 10, and FIG. 1 (B). As shown in FIG. 3, the upper and lower portions of the connecting portion 31 are notched. Therefore, the protrusion forming body A can be bent by bending the connecting portion 31 up and down.

  In addition to being molded by injection molding using a plastic material, the projection forming body A is molded from ceramics or stainless steel according to the walking surface to be laid. However, in the case of bending at the connecting portion 30, it is necessary to mold from a flexible material.

In order to configure the visually impaired person guiding block using the protrusion forming body A, a block body B as shown in FIG. 3 is used.
The block body B is a rectangular block in plan view formed from concrete or the like. A plurality of fitting grooves 40 into which the feet 20 of the protrusion forming body A are fitted are formed on the plane of the block body B. Since the two foot portions 20 are formed on the top plate 10 so that the cross-sectional shape of the projection forming body A is a gate shape, a pair of fittings are made in accordance with the interval between the two foot portions 20. The interval between the grooves 20 is set. Furthermore, a total of eight fitting grooves 40 are formed in the block body B of the present embodiment at a predetermined interval so that four projection forming bodies A can be fitted in parallel. The interval between the fitting grooves 40 is set so that the projection forming bodies A that are fitted in parallel have an array of linear projections defined in JIS T9251.

The depth of the fitting groove 40 is sufficient to fit all the feet 20 and the back surface of the top plate 10 is in contact with the surface of the block body B.

At this stage, the pressure contact protrusion 21 is caught on the side surface of the fitting groove 40, and the foot portion 20 is not fully fitted in the fitting groove 40, and the protrusion forming body A is in a floating state. Moreover, the space | interval of the fitting groove 40 used as a pair is set so that it may become like this.

(3) Crimp formation body crimping Next, the projection formation body A and the block body B are crimped | bonded by hitting the projection formation body A with a hammer. At this time, as shown in FIG. 4 (B), the foot 20 is slightly bent inward so that the pressure contact protrusion 21 comes into contact with the side surface of the fitting groove 40. Therefore, the pressure contact protrusion 21 is fitted by the elastic force of the foot 20. The side surfaces of the mating grooves 40 are pressed against each other, so that the protrusion forming body A is hardly peeled off from the block body B. Further, since the adhesive S enters the adhesive groove 12 on the back surface of the top plate 10 and the contact area with the adhesive S increases, the protrusion forming body A and the block body B can be firmly bonded. For this reason, even if the load and impact at the time of a person's walk or boarding a vehicle apply, the protrusion formation body A does not peel easily from the block body B.

  By fitting the protrusion forming body A to the block body B through the above steps, a visually impaired person guiding block C as shown in FIG. 5 can be obtained. The visually impaired person guiding block C has a linear protrusion and serves as a guiding block (linear block) for instructing the moving direction.

In the visually impaired person guide block C, if the color of the block B is similar to the walking surface on which the color is laid, even if it is laid on the colored walking surface, the scenery is not impaired. Further, if the color of the projection forming body A is a color having a stronger contrast than the color of the block body B, the visibility of the projection forming body A can be increased and guided easily.
Since the protrusion forming body A and the block body B are manufactured separately and the color can be selected at the construction site, it is easy to adjust such a color.

In addition to fitting the protrusion forming body A to the block body B, the fitting groove may be cut directly on the walking surface and fitted to the fitting groove.
Further, when laying on a bent walking surface, the projection forming body A can be bent by bending the connecting portion 31, so even when using a bent block body or directly laying on the walking surface. The top plate 10 can be laid in close contact.

  Generally, a plastic molded product may be warped, but even when the protrusion forming body A is warped, the warping can be canceled by bending the connecting portion 31, so that it is laid in close contact with the block body B. can do.

  When the projection forming body A is formed from a hard material such as ceramics, the foot portion 20 cannot be bent in the fitting to the block body B as described above. In this case, it is preferable that the pressure contact protrusion 21 is not provided, and the foot 20 and the fitting groove 40 are bonded with the adhesive S instead.
