Tactile signalling structure for sight disabled people incorporated in conventional paving

摘要

The described signalling structure (1) comprises a plate-like element (2) set in coplanar relation with a floor (3) adjacent the obstacle to be signalled and provided with a number of surface projections (6) having an elongated configuration, aligned so as to form several parallel rows (7) in side by side relation and extending transversely to the user's advance direction towards the obstacle or dangerous area to the signalled. The surface projections (6) can be easily recognized to the touch by a blind person walking towards the obstacle or the signalled dangerous area.
