Abstract: This invention's purpose is to quickly and safely evacuate people from the highest stories of a high-rise building. It is a slide, much like those on airplanes, but with more features and uses. Another part of this creation is a movable slide that is attached to a funnel, which can be carried around on fire trucks and attached to the fire truck's crane when needed for use. There is also a machine that can be used to re-wrap the slide once it has been used. The slides are packed inside an exact windowsill and will roll out of its storage space when called for. There is one every few stories and the slides are at intervals so that no collision will occur. Another feature of the slide is clear plastic covering over the top to keep people in and make it possible to direct traffic. The most important attribute of this invention is the plastic sheets that keep the walls and the slide stiff. It is through these that the air is pumped into the slide.

Abstract: A stairway slide assembly including an anchoring approach pad at the top of the stairway, an intermediate inflatable slide section for overlying the stairway steps and an deceleration section at the bottom of the stairway. A slide section includes a plurality of inflatable, longitudinally extending air passages which are formed by sealing laterally spaced apart elongate confronting portions of a pair of air impervious sheets. An inflatable support base is coupled to and underlies the slide and includes transversely extending inflatable air passages received on the steps and supporting the underside of the slide in spaced relation with the underlying steps.

Abstract: The invention relates to an improved escape system including a chute adapted to compensate for varying vertical distance. Elastic cords extend in a course of direction which progresses differently from vertically when the escape system has been launched and the chute is hanging vertically from the higher position to the lower position, such that tension is applied to the elastic cords. By the present invention it is realised that a longer elongation of the chute may be obtained without increasing the minimum length when the elastic cords extend in such a course of direction, because the cords hereby become longer than in a course of direction progressing straight and vertically. Since any elastic cord has a maximum strain which it may safely endure, a longer extent of such a cord subjected to maximum strain will result in a longer elongation, and hence longer maximum length while maintaining or even reducing the minimum length.
