COLLAPSIBLE ESCAPE LADDER WITH GUARDS
A collapsible escape ladder, including a first upright, a second upright, and a plurality of elongated rungs that extend between the first and second uprights and that are rotatably attached to the first and second uprights about a first and second rotation axis, respectively, that extend perpendicular to a ladder plane spanned by the first and second uprights and the rungs. The ladder has a closed state where the rungs are substantially hidden between the uprights and an open state where the rungs extend between the uprights and perpendicular to a building wall and wherein the ladder extends downward from an escape point to the ground. The ladder further comprises a plurality of rigid, elongated guard profiles extending parallel to the rungs, and each guard profile is connected to the uprights through a first side profile between one end of the guard profile and the first upright and a second side profile between the other end of the guard profile and the second upright, and wherein the guard profile is moveable from a position adjacent the rungs in the closed state to a position at a distance perpendicular to the ladder plane in the open state.
