The foot plate (1) consists of a circular metal disc, with a diameter substantially equal to that of the platform (2), while the platform (2), also made of sheet metal, is integral with a circular protective edge (1b) extending to the foot plate, and the bottom elements (4a) of the two vertical members are linked by a horizontal cross member (10), which, arranged at the level of an adult's knee, is itself reinforced by a sloping bar (11) extending between said cross member and the front part of the platform (2).
