Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blind guide plate which is laid on a sidewalk, a platform, a passage inside or outside a building, etc., for guiding a blind person, a low vision person and the like.

[0002]

2. Description of the Related Art Conventionally, this type of blind guide plate is made of a material such as concrete, synthetic resin, ceramic, metal or the like. In addition, a plurality of guide projections are provided so that a blind person can sense the safety side, the direction, and the like. Then, the blind person can perceive the shape and the like by his / her sole tactile sensation by walking on the guide protrusion, and can recognize the danger zone and the walking direction.

[0003]

However, since the protruding surface of the guide projection in the above-mentioned conventional blind guide plate is smooth, it is difficult to walk without being kicked, and it is easy to slide.
Since the surface of the main body between the guide protrusions is also smooth, there is a problem that the bicycle or the like easily slips when passing. Further, when the blind guide plate is wet by rainfall or the like, or when dust or the like floats together with water, the guide plate tends to be more slippery.

Further, since the guide projection is sensed on the sole of the foot, it is necessary to further devise the guide projection to make it easier to detect. In particular, since amblyopia suffers from less visual impairment than blind people, it is generally considered that the sensation is less sharp than a blind person, and since they tend to rely on visual acuity, they merely provide a guiding projection having a smooth protruding surface. The blind board is not enough.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has as its object to provide a blind guide plate which is hard to slip when walking and is easily perceived by a blind person or the like.
In addition, another object of the present invention is to provide a blind guide plate that is sufficiently considered for the visually impaired.

[0006]

The present invention has been made to solve the above-mentioned problems, and means for solving the problems are as follows: guide projections 2 having a predetermined shape on the upper surface of a blind guide plate body 1. In at least two or more blind guide plates, the projecting surface of the guide projection 2 is formed into a rough rough surface, and the blind guide plate main body 1 between the guide projections 2 ... The surface 1a of the above is formed into a rough surface having irregularities, and moreover, a smooth surface is formed between the protruding surface of the guide projection 2 formed on the rough surface and the surface 1a of the blind guide plate body 1.

[0007] In the blind guide plate comprising such means, since the protruding surface of the guide projection 2 is formed as a rough surface having irregularities, the foot sole becomes rough when walking on the protruding surface. In addition, it is easy for even a low vision person to perceive, and furthermore, the frictional resistance with the sole increases due to the rough surface, so that pedestrians and the like are less likely to slip.

In addition, since the surface 1a of the blind guide plate main body 1 between the guide projections 2 ... Or around the guide projections 2 ... Is formed into a rough rough surface, it is possible to prevent the tire from contacting the tire even if a bicycle or the like passes through it. Friction resistance increases, and it becomes difficult to slip. Further, in general, between the protruding surface of the guide projection 2 and the upper surface of the blind guide plate body 1, that is, near the hem of the guide projection 2, is a portion where it is difficult for the soles of pedestrians, bicycle tires, etc. to come into contact. This is the part that is most likely to get dirty, and the dirt that is attached is difficult to remove. Therefore, if a smooth surface is formed between the protruding surface of the guide projection 2 and the surface 1a of the blind guide plate body 1 as in the above means, it is difficult for dirt to adhere to that portion and the adhered dirt can be removed easily.

[0009] Further, depending on the reflection of light, the contrast between the smooth surface and the protruding surface formed on the rough surface becomes vivid, and there is an aesthetic effect that the guide protrusion 2 appears to be raised from the plate surface.

Further, like the second means, the peripheral edge 2b of the protruding surface of the guide projection 2 formed on the rough surface and the peripheral edge 1b of the surface 1a of the blind guide plate body 1 formed on the rough surface are gradually smoothed. If it is made to be smooth, the boundary with the smoothly formed portion becomes unclear, and the rough surface and the smooth surface appear to move naturally, and it becomes difficult for the portion to become dirty.

The third means is to use a fluorescent glaze, a fluorescent paint or the like on any one or more of the surface 1a of the blind guide plate body 1, a part 1a 'of the upper surface and the protruding surface of the guide projection 2. Means are provided. In this way, the blind guide plate main body 1 provided with the fluorescent means accumulates sunlight in the daytime, and at night, that portion is more prominently fluorescent than the surroundings,
Amblyopia can visually recognize the blind guide plate.
