Abstract

The patent consists of a flap which can be employed for covering the cavity corresponding to the lower profile of a sliding window when the sash opens. Said system subsequently allowing automatic withdrawal of said flap in a side-by-side position and not interfering with the sliding of said door during closing: said automatic withdrawal thus taking place in correspondence with the sliding in the opposite direction of the same door. This double synchronized movement with opening and closing of said sliding door favors the crossing of the threshold by users but above all by wheelchairs, trolleys, pushchairs and similar. The system object of the patent proposal is based on a mechanism controlled directly by the sliding of said sliding door which allows the automatic movement of said flap from a first horizontal position covering the frame track to a second lateral position next to the sliding door and vice versa.
