Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
157 words
An airplane comprising: (a) a main section including a cockpit and a fuselage having an elongated receptacle with a floor therein, (b) a detachable air tight passenger compartment having a plurality of seats for passengers, (c) means for upwardly ejecting said passenger compartment from said receptacle of said fuselage of said main section when said airplane is in danger of crashing; (d) means for gently floating said passenger compartment to earth; (e) a plurality of tracks spaced apart and rearwardly angled to sides of said receptacle in said fuselage; and (f) a plurality of rails spaced apart and rearwardly angled to sides of said passenger compartment, said rails ride in said tracks so that when said passenger compartment is upwardly ejected from said receptacle of said fuselage said passenger compartment will travel upwardly and rearwardly away from said airplane whereby the continued forward movement of the main section creates an air lifting motion on the passenger compartment.
Claim 2
Dependent Claim
157 words
An airplane comprising: (a) a main section including a cockpit and a fuselage having an elongated receptacle with a floor therein, (b) a detachable air tight passenger compartment having a plurality of seats for passengers, (c) means for upwardly ejecting said passenger compartment from said receptacle of said fuselage of said main section when said airplane is in danger of crashing; (d) means for gently floating said passenger compartment to earth; (e) a plurality of tracks spaced apart and rearwardly angled to sides of said receptacle in said fuselage; and (f) a plurality of rails spaced apart and rearwardly angled to sides of said passenger compartment, said rails ride in said tracks so that when said passenger compartment is upwardly ejected from said receptacle of said fuselage said passenger compartment will travel upwardly and rearwardly away from said airplane whereby the continued forward movement of the main section creates an air lifting motion on the passenger compartment.
Claim 3
Dependent Claim
88 words
An airplane as recited in claim 1 wherein said ejecting means comprises: (a) a plurality of lifting cylinders spaced apart and mounted to said floor of said receptacle of said fuselage of said main section; and (b) a plurality of lifting blocks spaced apart and formed to underside of said passenger compartment to rest upon said lifting cylinders so that when said lifting cylinders are activated said lifting blocks will be pushed away from said floor allowing wind to further push the passenger compartment away from the airplane.
Claim 4
Dependent Claim
30 words
An airplane as recited in claim 1 further comprising a blow away tail so that said tail will be free from said fuselage when said passenger compartment is ejected therefrom.
Claim 5
Dependent Claim
64 words
An airplane as recited in claim 3 wherein said floating means comprises: (a) said pasenger compartment having a plurality of spaced apart top chambers formed therein; (b) a plurality of parachutes attached within said top chambers of said passenger compartment; and (c) a plurality of covers each removably attached to each of said top chambers to hold said parachutes within said chambers until released.
Claim 6
Dependent Claim
92 words
An airplane as recited in claim 4 further comprising: (a) said passenger compartment having at least one bottom chamber formed therein; and (b) at least one elongated air bag attached within said at least one bottom chamber so that when said passenger compartment is ejected from said receptacle of said fuselage said at least one air bag will be inflated to cushion shock of landing even in a close ground crash whereby a great deal of the shock will be absorbed so as to prevent injury to passengers within said passenger compartment.
Claim 7
Dependent Claim
120 words
An airplane as recited in claim 5 wherein said passenger compartment further comprises: (a) a front air tight entrance door so that pilot and crew of said airplane can leave said cockpit after throttling down speed of said airplane from cruising speed to just above stalling speed whereby in time it takes for said airplane to slow down said crew will enter said passenger comparment through said front door and activate a release mechanism to operate said lifting cylinders for ejecting said passenger compartment and jettison said parachute covers and said tail simultaneously; and (b) a rear airtight exit door so that said pilot, crew and said passengers can exit therefrom when said passenger compartment is safely on said earth.
Claim 8
Dependent Claim
89 words
An airplane as recited in claim 6 further comprising: (a) a plurality of first windows spaced apart between said tracks in said sides of said receptacle in said fuselage; and (b) a plurality of second windows spaced apart between said rails in said sides of said passenger compartment so that said second windows will align with said first windows when said passenger compartment is placed within said receptacle of said fuselage allowing said passengers in said seats to look out of said airplane during normal operations of said airplane.
