Inflatable evacuation slide with arch support
First Claim
1. An inflatable evacuation device adapted for deployment from an exit opening of a structure, the inflatable evacuation device comprising:
- an inflatable slide portion, comprising;
at least a first inflatable elongate beam; and
a second inflatable elongate beam spaced from the first inflatable elongate beam;
a floor extending between the at least first and second inflatable elongate beams, the floor being constructed of a flexible material; and
an inflatable arch-shaped support portion comprising at least one substantially vertically oriented inflatable curved beam connected to the inflatable slide portion, such that forces generated at least at a central section of the inflatable slide portion are transferred to the at least one substantially vertically oriented curved beam to thereby support at least the central section.

Abstract
An inflatable evacuation device includes an inflatable slide portion and an inflatable arch-shaped support portion for supporting the inflatable slide portion. The inflatable slide portion has a support frame with a first inflatable elongate beam and a second inflatable elongate beam spaced from the first inflatable elongate beam. A floor extends between the first and second inflatable elongate beams and is constructed of a flexible material. The inflatable arch-shaped support portion comprising first and second inflatable curved beams connected to the inflatable slide portion such that forces generated at least at a central region of the inflatable slide portion are transferred to the curved beams to thereby support at least the central region.

27. An inflatable evacuation device adapted for deployment from an exit opening of a structure, the inflatable evacuation device comprising:
-
an inflatable slide portion including at least first and second inflatable elongated beams spaced from each other;
a floor extending between said at least first and second inflatable elongated beams; and
an inflatable arch-shaped support portion comprising first and second inflatable curved beams oriented substantially vertically, whereby forces generated at least at a central section of the inflatable slide portion are transferred to the substantially vertically oriented first and second inflatable curved beams to thereby structurally support at least the central section when the inflatable slide portion is at least partially spaced from a supporting surface.
