Abstract
Abstract An inflatable slide device for emergency evacuation from structures such as aircraft, offshore drilling platforms, etc. The slide device comprises two assemblies of tubular members defining two mutually independent inflatable chambers. One chamber includes tubular members supportive of the slide panel of the device and certain side rail tubular members as well as another tubular member functioning as the central slide support. The other chamber also includes tubular members supportive of the slide panel of the device and certain other side rail tubular members as well as another tubular member also functioning as an additional central slide support.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
113 words
An inflatable slide device for emergency evacuation having a flexible panel defining a slide surface extending from a head end of the inflatable slide device to a foot end of the inflatable side device and a first plurality of interconnected tubular members defining a first inflatable chamber, a second plurality of interconnected tubular members defining a second inflatable chamber fluidly independent of said first chamber, each of said chambers including tubular rail means along portions of each lateral margin of said panel, said rail means being raised from said flexible panel along the slide and contoured for being raised even higher from the slide panel adjacent the head end of the slide device.
Claim 2
Dependent Claim
113 words
An inflatable slide device for emergency evacuation having a flexible panel defining a slide surface extending from a head end of the inflatable slide device to a foot end of the inflatable side device and a first plurality of interconnected tubular members defining a first inflatable chamber, a second plurality of interconnected tubular members defining a second inflatable chamber fluidly independent of said first chamber, each of said chambers including tubular rail means along portions of each lateral margin of said panel, said rail means being raised from said flexible panel along the slide and contoured for being raised even higher from the slide panel adjacent the head end of the slide device.
Claim 3
Dependent Claim
35 words
An inflatable slide device as set forth in claim 1 wherein each chamber includes a central longitudinal support tube to divide the slide panel into two lanes from the head end to the foot end.
Claim 4
Dependent Claim
39 words
The device as set forth in claim 1 and further including a plurality of truss supports extending beneath said panel member transverse to the axial center line of the device, said truss supports being fluidly independent of each other.
Claim 5
Dependent Claim
88 words
An inflatable slide device for emergency evacuation having a flexible panel defining a slide surface extending from a head portion of the inflatable slide device to a foot portion of the inflatable slide device and a first plurality of interconnected tubular members defining a first inflatable chamber, a second plurality of interconnected tubular members defining a second inflatable chamber fluidly independent of said first chamber, each of said chambers including tubular rail means along portions of each lateral margin of said panel and a central longitudinal support tube.
Claim 6
Dependent Claim
88 words
An inflatable slide device for emergency evacuation having a flexible panel defining a slide surface extending from a head portion of the inflatable slide device to a foot portion of the inflatable slide device and a first plurality of interconnected tubular members defining a first inflatable chamber, a second plurality of interconnected tubular members defining a second inflatable chamber fluidly independent of said first chamber, each of said chambers including tubular rail means along portions of each lateral margin of said panel and a central longitudinal support tube.
Claim 7
Dependent Claim
22 words
An inflatable slide device as set forth in claim 4 wherein said central longitudinal support tubes are located one above the other.
Claim 8
Dependent Claim
33 words
An inflatable slide device as set forth in claim 4 wherein the top of each central longitudinal support tube is located in a plane beneath the top of its associated tubular rail means.
Claim 9
Dependent Claim
142 words
An inflatable slide device for emergency evacuation having a first plurality of tubular members defining a first inflatable chamber a second plurality of tubular members defining a second inflatable chamber fluidly independent of said first chamber, a flexible panel defining a slide surface extending from a head end of the slide device to a foot end of the slide device, each of said chambers including an inflatable tubular means longitudinally disposed beneath said panel and extending adjacent the longitudinal center line of the panel along its length to support said panel and form said slide surface into two lanes each of said chambers also including tubular means disposed adjacent the edges of the panel along its length to define side supports and each of said chambers also including tubular means beneath the panel at a central location to define lateral truss supports.
Claim 10
Dependent Claim
142 words
An inflatable slide device for emergency evacuation having a first plurality of tubular members defining a first inflatable chamber a second plurality of tubular members defining a second inflatable chamber fluidly independent of said first chamber, a flexible panel defining a slide surface extending from a head end of the slide device to a foot end of the slide device, each of said chambers including an inflatable tubular means longitudinally disposed beneath said panel and extending adjacent the longitudinal center line of the panel along its length to support said panel and form said slide surface into two lanes each of said chambers also including tubular means disposed adjacent the edges of the panel along its length to define side supports and each of said chambers also including tubular means beneath the panel at a central location to define lateral truss supports.
Claim 11
Dependent Claim
32 words
An inflatable slide device as set forth in claim 7 wherein at least one of said last mentioned tubular means extends around to the sides of the slide device for added support.
Claim 12
Dependent Claim
41 words
An inflatable slide device as set forth in claim 8 and further including strap means extending beneath said panel member parallel with the axial center line of the device from the head end to the foot end for added longitudinal support.
