摘要
The ladder has a balustrade tube (13) associated to a lower platform (15) and including lower and upper rails (17, 19) arranged at about 0.5 mm and 1 mm from the platform, respectively. The rails form a peripheral edge articulated to an upper plane (5). The edge is connected to side legs (27) slidably connected to a post (21) in the plane. The platform is foldably mounted in an out of service folded position in which the platform and tube are brought in the ladder plane to occupy only a less volume, from a service position where the platform and tube are deployed to protect a person.
