Abstract
Abstract An escape slide (10) for evacuating personnel from an aircraft wing or other elevated surface where persons to be evacuated must walk a short distance before sliding down the slide. The escape slide (10) has an entrance portion (13) with a walkway (17) and a walkway ramp (19) of an inflatable bulkhead construction providing a firm walkway surface. The slide portion (14) joins the entrance portion (13) and is inclined toward the ground. When used on an aircraft wing (12) with flaps, the bottom of the slide portion (14) is engageable with and supported by the flaps at different operating positions. A support pillow (45) attached to the bottom of the slide portion (14) is engageable with the flap in the fully extended landing position. Inflatable indicator tubes (58) are also attached to and in communication with the inflatable members of the slide to indicate when the slide is inflated and ready for passengers.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
161 words
An escape slide adapted to be inflated and extend from a supporting surface (12) at an elevated position to a lower surface comprising an inflatable entrance portion (13) with a walkway (17) for mounting on said supporting surface and a slide portion (14) extending from an entrance end at said elevated position to an exit end (16) at said lower surface, said entrance portion (13) of said escape slide (14) including a plurality of supporting tubes (29,32,33,43,44) having top and bottom surfaces, at least some of said bottom surfaces of said supporting tubes being in the same plane for engagement with said supporting surface (-12), at least some-of said top surfaces of said supporting tubes providing support for said walkway (17) and all of said supporting tubes being located above said plane of said bottom surfaces and below said walkway to provide a stable support for persons traversing said walkway (17) to said entrance end (15) of said slide portion (14).
Claim 2
Dependent Claim
161 words
An escape slide adapted to be inflated and extend from a supporting surface (12) at an elevated position to a lower surface comprising an inflatable entrance portion (13) with a walkway (17) for mounting on said supporting surface and a slide portion (14) extending from an entrance end at said elevated position to an exit end (16) at said lower surface, said entrance portion (13) of said escape slide (14) including a plurality of supporting tubes (29,32,33,43,44) having top and bottom surfaces, at least some of said bottom surfaces of said supporting tubes being in the same plane for engagement with said supporting surface (-12), at least some-of said top surfaces of said supporting tubes providing support for said walkway (17) and all of said supporting tubes being located above said plane of said bottom surfaces and below said walkway to provide a stable support for persons traversing said walkway (17) to said entrance end (15) of said slide portion (14).
Claim 3
Dependent Claim
27 words
An escape slide in accordance with claim 1 wherein said supporting tubes (29,32,33,43,44) are in side-by-side relationship providing said walkway with forming a relatively rigid smooth surface.
Claim 4
Dependent Claim
35 words
An escape slide in accordance with claim 2 further comprising an inflatable, substantially rigid walkway ramp (19) having an upper surface and a lower surface extending outwardly from an edge of said entrancet portion (13).
Claim 5
Dependent Claim
77 words
An escape slide in accordance with claim 3 wherein said walkway ramp (19) has supporting tubes formed by bulkheads (53,54,55) extending between said upper surface (49) and said lower surface (52) of said ramp and said bulkheads (55) in close proximity to said edge (18) having a greater length than other of said bulkheads remote from said edge so that said upper surface of said ramp is inclined from said supporting surface (12) to said edge (18).
Claim 6
Dependent Claim
44 words
An escape slide in accordance with claim 1 wherein said slide portion (14) has an inflatable indicator tube (57,58) attached to and in communication with said slide portion (14) for indicating inflation of said slide portion upon inflation and extension of said escape slide.
Claim 7
Dependent Claim
100 words
An escape slide in accordance with claim 1 wherein said supporting surface is an aircraft wing (12) having a flap (46) movable to different positions during different operating conditions, said slide portion (14) having an inflatable support means (45) attached to the bottom of said slide portion and said flap (46) being engageable with the bottom of said slide portion in certain operating positions of said flap and being engageable with said inflatable support means (45) in other operating positions of said flap to support said escape slide (10) in an inclined position for evacuation of passengers from the aircraft.
Claim 8
Dependent Claim
48 words
An escape slide in accordance with claim 6 wherein said inflatable supporting means includes an inflatable pillow member (45) attached to and in communication with inflatable members of said slide (10) and said pillow member being engageable with said flap in said other operating positions of said flap.
Claim 9
Dependent Claim
27 words
An escape slide in accordance with claim 7 wherein said other operating positions of said flap include the generally extended position of said flap (46) during landing.
Claim 10
Dependent Claim
82 words
An escape slide in accordance with claim 6 wherein said supporting means includes a second inflatable support means (47,48) at the bottom of said slide portion (14) at a position adjacent said first-mentioned support means (45) and toward said exit end of said slide portion (14) from said first-mentioned support means for engagement of said second support means by said first-mentioned support means (45) upon engagement of said first-mentioned support means with said flap in said certain operating positions of said flap.
Claim 11
Dependent Claim
42 words
An escape slide in accordance with claim 9 wherein said first-mentioned support means (45) extends across said slide portion (14) and said second support means (47, 48) includes two spaced-apart inflatable pillow members attached to and in communication with said slide member.
