Abstract

The bonding of the rungs (14) of a ladder, in the side rails (12), has an angled surface (32) at the side rail (12) next to the rung (14) to take up loading forces and also form a rotating limit stop (34) for the rung (14). A further limit surface (32) is formed opposite the rotating limit. The rung (14) has an out-of-round shape, and its end is formed into a shoulder (30).
