Escape structure

An escape structure, which is applicable to an external wall of a building, the escape structure comprising:

• at least two slide bars, which are mounted to the external wall of the building, the two slide bars being spaced from each other by a distance;
• a plurality of foot board units, which are mounted to the slide bars, the foot board units being arranged on the two slide bars in an alternate manner;
• and
• a surround cover unit, which surrounds the slide bars to form an escape space, one side of the surround cover unit corresponding to an escaping site of the building for allowing an escaping person to enter and be constrained in the escape space;
• wherein each of the slide bars is formed in a sectioned arrangement to form sites between the sections to mount the foot board units, and each of the foot board units comprises a bottom plate, an elastic body, and a foot board, wherein the bottom plate comprises a joining tube mounted thereto by penetrating therethrough, such that upper-end and lower-end parts of the joining tube respectively form an upper section portion and lower section portion respectively projecting from upper and lower sides of the bottom plate and the upper section portion and the lower section portion of the joining tube are respectively joined to separate sections of the slide bar, wherein the elastic body is arranged on the bottom plate, and the foot board is fit over the upper section portion of the joining tube and arranged on the elastic body, such that when the foot board receives a pressing force acting thereon, the elastic body presents a rebounding force through a spring force thereof, one side of the bottom plate being fixedly mounted to the external wall of the building so as to fix the slide bars to the external wall of the building.
