Abstract

Disclosed is an emergency slide system comprising a slide having a telescoping structural support, and a slide surface. The emergency slide system further comprises a gas deployment device comprising a gas generator, compressed gas cylinder, or both. The gas deployment device may further include an aspirator, according to various embodiments. The telescoping structural support provides a more compact and quickly deployable system.

First claim

The invention claimed is:

1. An emergency slide system comprising:
a slide including a telescoping structural support, and a fabric wrap; and
a gas deployment device configured to deploy said slide;
wherein said telescoping structural support comprises a first rail and a second rail forming longitudinal borders of said slide, said first rail comprising a first set of telescoping segments, and said second rail comprising a second set of telescoping segments, wherein corresponding telescoping segments of the first set of telescoping segments and the second set of telescoping segments are attached to one another via an attachment segment, wherein the attachment segment comprises a first loop that wraps around the first set of telescoping segments and a second loop that wraps around the second set of telescoping segments, wherein said first set of telescoping segments comprise a plurality of interlocking nested tubes, the plurality of interlocking nested tubes having a closed bottom end and an open top end, wherein deployment of said first set of telescoping segments is effectuated by forcing gas through said open end, wherein said fabric wrap comprises a slide surface and comprises a closed bottom end and an opened top end, wherein said fabric wrap envelopes the telescoping structural support and the attachment segment.

2. The emergency slide system of claim 1 , wherein said gas deployment device is configured to force gas through said open end.

3. The emergency slide system of claim 1 , wherein said emergency slide system is a component of an aircraft.

4. The emergency slide system of claim 1 , said gas deployment device comprising at least one of a gas generator, a compressed gas cylinder, or a combination thereof.

5. The emergency slide system of claim 1 , said emergency slide system being configured to pack within a storage compartment.

6. The emergency slide system of claim 5 , said emergency slide system configured to deploy upon opening said storage compartment.

7. The emergency slide system of claim 1 , wherein the attachment segment is rigid.

8. An emergency slide system comprising:
a slide including a telescoping structural support, and a fabric wrap; and
a gas deployment device configured to deploy said slide;
wherein said telescoping structural support comprises a first rail and a second rail forming longitudinal borders of said slide, said first rail comprising a first set of telescoping segments having a closed bottom end and an open top end, and said second rail comprising a second set of telescoping segments, wherein deployment of said first set of telescoping segments is effectuated by forcing gas through said open end, wherein corresponding telescoping segments of the first set of telescoping segments and the second set of telescoping segments are attached to one another via an attachment segment, wherein the attachment segment comprises a first loop that wraps around the first set of telescoping segments and a second loop that wraps around the second set of telescoping segments, wherein said fabric wrap comprises a slide surface and comprises a closed bottom end and an opened top end, wherein said fabric wrap envelopes the telescoping structural support and the fabric wrap also envelopes the attachment segment.
