In a rung ladder having lateral pairs of spars (10, 11), on which a number of ladder rungs (12) keep the spars (10, 11) at a distance from one another, the ladder rungs (12) are connected at the ends to the spars (10, 11) in an articulated manner, in such a way that they can thus be folded parallel to the spars (10, 11) in an articulated manner. At the same time, fastened in the middle of each divided ladder rung (12) is a rod (15) which is mounted thereon in an articulated manner and the lower end of which can serve as a foot (17) for the position of use.
