PAVING TILE FOR GUIDANCE OF BLIND PERSONS

摘要

The invention relates to a concrete pavement tile, which produces a clear ly recognizable sound when touched with a blind person's cane or a white stick. In practice, it appears useful to incorporate sound sources in guide paths for the blind. The invention has solved this problem by providing a pavement tile with an upper plate of metal, which is supported by the tile at its circumference. The pla te can be provided with regularly distributed outwardly projecting tears, bumps or ledges. Below the plate there is a sound space which can be formed by pressing the plate, upwardly convex, whereas a hollow executed tile give the same effect.
