The invention relates to an arrangement in a foldable fire escape ladder. This comprises individual, elongate spaced-apart steps (32) which are connected to each other. Each step has a tread (34) and at least one side wall. In the longitudinal direction of each step (32) extends a groove integrated with the step. A spacer member (46) is hingedly mounted in the groove of one of the steps (32). Further, there is provided a guide means for positively guiding the spacer member (46) from a first, folded-in position in which, in the folded state of the ladder, it engages the ladder, to a second, folded-out position in which, in the unfolded state of the ladder, it extends at approximately right angles to the direction of unfolding of the ladder and to an engagement surface therefor. |
