ABSTRACT:
The threshold includes a shaped support plate of steel or the like with a sinuous profile which forms at least one longitudinal, substantially U-shaped loop between two raised portions. A profiled cover element of aluminum or the like is located on the plate and forms at least one guide for guiding the running of a door panel. This guide penetrates into the corresponding loop of the support plate. The threshold further includes fixing devices for anchoring it in the zone connecting the landing and the lift shaft or well.
