DISPOSITIF DE CONDAMNATION DE L'ACCÈS INFÉRIEUR À UNE ÉCHELLE
The invention relates to a device for the controlled access to an upper area, having a ladder (1) with transverse rungs (3) and longitudinal uprights (1a, 1b), which is flat with a mean plane (P), extending between a lower area that is freely accessible to a user and said upper area, a means for hindering or preventing the use of at least some of the rungs of this ladder, formed by an elongate panel (4), and means for connecting the latter to the ladder, which make it possible to place the panel (4), in a first state, pressed against a face of the ladder (1) and, in a second state, away from this face of the ladder, characterized in that said panel (4) is designed so as to have a running section, transverse to its major axis, at least a central part (4a) of which crosses the mean plane (P) of the ladder, and to have cutouts (5) in this central part (4a) for each rung (3) to pass through, when the panel (4) is in its first state.
