Abstract

A ladder having four-point contact with the underlying surface comprises ladder rungs (5), side members or stringers (8) and support legs (6) that are fastened at one end to respective side members (8) for pivoting outwards therefrom. Each support leg (6) independently is rapidly deployable by means of a pressure device (1) acting between the stringer (8) and the support leg (6). The ladder itself may be of any type, but is intended particularly for rescue purposes where time is of critical importance.
