A platform for research: civil engineering, architecture and urbanism
A safety ladder (100) for mounting between a support surface (1) and a ground surface (2) includes two support assemblies (20,20') and parallel step members (30) pivoted between the support assemblies (20,20'). Each support assembly (20,20') includes first and second support rods (21,22) each having upper and lower ends. The upper ends (211,221) of the first support rods (21) of the support assemblies (20,20') are configured to be pivoted to the support surface (1). The safety ladder (100) is movable between a use position, in which the lower ends (212,222) of the first and second support rods (21,22) of the support assemblies (20,20') are adapted to simultaneously contact the ground surface (2), and a storage position, in which the first and second support rods (21,22) stand substantially perpendicular relative to the ground surfaces (2).
