Abstract

An inflatable, generally horizontal, elevated platform fastened to a supporting structure is connected to an inflatable escape slide extending downwardly at an inclination from the platform to a lower surface. An elongated tension strap is connected at one end to the platform adjacent the supporting structure and at the other end to the slide at a position around midway down the slide to reinforce the platform and maintain the horizontal position of the platform under the weight of persons using the platform and slide.

The slide may have a laterally extending inflatable member on the underside with longitudinally extending slide reinforcing tension members cooperative with the laterally extending inflatable member to provide a truss-like structure. The tension strap for reinforcing the platform may be connected to the slide at a position at the laterally extending inflatable member at one end and be connected to the platform at a position adjacent the supporting structure at the other end. The platform also may have an edge connected to the slide which is not parallel to the edge adjacent the supporting structure in which case the tension member is located on the side of the platform where the edges are the greatest distance apart.

Claims

1. An escape slide and platform assembly adapted to be inflated and extend from a supporting structure at an elevated position to a lower surface comprising a generally horizontal platform, an escape slide inclined downwardly from said platform and extending to said lower surface, and an elongated platform supporting tension member means connected at one end to said platform at a first position spaced from said slide and connected at the other end to said slide at a second position spaced from said platform to sustain said platform in said generally horizontal position under the weight of persons using the assembly.

2. An escape slide and platform assembly according to claim 1 wherein said first position on said platform at which said platform supporting tension member means is connected at one end is located adjacent said supporting structure.

3. An escape slide and platform assembly according to claim 2 wherein said second position at which said other end of said platform supporting tension member means is connected to said slide is located at a distance from said platform of around one-half the length of said slide.

4. An escape slide and platform assembly according to claim 1 wherein said slide and platform comprise a series of inflatable tubes of flexible material and said platform supporting tension member means is a flexible strap adhered to said platform and to said slide by an adhesive.

5. An escape slide and platform assembly according to claim 1 wherein said platform has a first side and an opposing second side, a first edge connected to said slide and an opposing second edge for abutting said supporting structure, said first edge being closer to said second edge at said first side than at said second side and said first position on said platform being adjacent said second side and next to said supporting structure.

6. An escape slide and platform assembly according to claim 1 wherein said slide has a laterally extending inflatable member attached to the underside of said slide, an elongated longitudinally extending slide reinforcing tension member abuttingly engaging the lower surface of said laterally extending member and cooperative with said slide and laterally extending member to provide a truss-like structure and said second position at which said platform supporting tension member means is connected being located where said slide reinforcing tension member engages said laterally extending member.

7. An escape slide and platform assembly according to claim 6 wherein said laterally extending member is located at a distance from said platform equal to around one-half the length of said slide.

8. An escape slide and platform assembly according to claim 1 wherein said slide is an elongated inflatable body and said platform is an extension of said body.

9. An escape slide and platform assembly according to claim 8 wherein said slide has a pair of longitudinally extending inflatable lower side tubes extending into said platform and connected to a first laterally extending inflatable end tube adjacent said supporting structure.

10. An escape slide and platform assembly according to claim 9 wherein said slide has a laterally extending inflatable member attached to the underside of said slide, an elongated longitudinally extending slide reinforcing tension member abuttingly engaging the lower surface of said laterally extending member and cooperative with said slide and laterally extending member to provide a truss-like structure and said second position where said platform supporting tension member means is connected being located where said slide reinforcing tension member engages said laterally extending member.

11. An escape slide and platform assembly according to claim 9 wherein said slide has a pair of inflatable upper side tubes attached to said first pair of lower side tubes and said pair of upper side tubes extend into said platform and are connected to a laterally extending inflatable tubular second end tube, said second end tube extending beneath said first end tube and adjacent said supporting structure and said first position being located on said second end tube.
