STOWABLE, UNOBTRUSIVE ACCESS AND ESCAPE DEVICES

摘要

To provide another way to exit and/or enter an elevated structure may include alternative access devices. For example, some of the windows on the upper floors of a building may be equipped with devices to allow occupants of those floors to exit and/or enter the building via the window. The devices may be integrated with the building. The alternative access devices also may be used for other applications. For example, the devices may provide access to a structure that is a considerable distance from the ground, such as a tree house or other play structure. The invented access device includes a chute mounted at the top to a pivotal frame mounted, for example near a window or other elevated opening, the chute having a connected or independently deployable step ladder therein and optionally spaced apart support members such as circular, rectangular or oval hoops therearound. The rungs of the step ladder provide a standoff for the webbed material of the chute. Stowage can be in a stowage receptacle mounted to an exterior portion of an elevated structure and deployment can be semi-automatic, reliable and smooth. In accordance with one embodiment of the invention, the access/escape device is hidden within and behind a box-like receptacle on an exterior wall of the building below a window sill. The receptacle generally includes aesthetic elements which closely correspond to aesthetic elements of the structure, rending the receptacle visually unobtrusive and relatively hidden upon casual observation.
