Abstract

Abstract A moveable wing aircraft including a quick release, attachment mechanism carrying the aircraft on a bomb rack or other carrier and a mechanism for deploying the moveable wing from its captive carry position to its extended free flight position are disclosed. The aircraft includes an elongate fuselage, a portion of the top surface of which is substantially flat in order to accommodate the moveable wing. The moveable wing is positionable between a captive carry position in which it is aligned with the longitudinal axis of the fuselage and an extended free flight position. The single, moveable wing is pivoted around a central point from its captive carry position to its extended free flight position such that it is substantially perpendicular to the aircraft fuselage. The quick release mechanism extends through apertures in the wing in its captive carry position and is spring biased to retract through the wing and into the aircraft fuselage when released from the bomb rack or other carrier. The deployment mechanism includes a spring loaded cable and pulley arrangement and serves to connect the moveable wing to the fuselage and to bias it from its captive carry position to its extended free flight position when activated upon release of the quick release mechanism.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 121 words
A retractable device for releasably attaching a first member to a second member comprising: a cylinder having a cylinder housing, an interior cylinder wall, a first end and a second end having means for connecting to said second member; a piston positioned in slideable engagement with said cylinder wall; a connecting rod having a hollow core and having extended and retracted positions and having a first end connected to said piston and a second end having means for releasable engagement with a deployment actuating mechanism connected to said first member; and spring means connected to said connecting rod and to said cylinder housing for biasing said connecting rod towards said cylinder second end, said spring means extending through said hollow core.
Claim 2
Dependent Claim 121 words
A retractable device for releasably attaching a first member to a second member comprising: a cylinder having a cylinder housing, an interior cylinder wall, a first end and a second end having means for connecting to said second member; a piston positioned in slideable engagement with said cylinder wall; a connecting rod having a hollow core and having extended and retracted positions and having a first end connected to said piston and a second end having means for releasable engagement with a deployment actuating mechanism connected to said first member; and spring means connected to said connecting rod and to said cylinder housing for biasing said connecting rod towards said cylinder second end, said spring means extending through said hollow core.
Claim 3
Dependent Claim 24 words
The retractable device of claim 1 further comprising: means in engagement with said cylinder for preventing said piston from sliding past a predetermined point.
Claim 4
Dependent Claim 35 words
The device of claim 2 wherein: said preventing means comprises a donut shaped stop secured in a fixed location against said cylinder and having a passageway there; and said connecting rod extends through said passageway.
Claim 5
Dependent Claim 31 words
The device of claim 3 wherein said piston has a threaded interior surface and said connecting rod has a threaded exterior surface for mating engagement with said piston threaded interior surface.
Claim 6
Dependent Claim 22 words
The device of claim 4 wherein said connecting rod second end means for releasable engagement with a deployment mechanism comprises an eyelet.
Claim 7
Dependent Claim 25 words
The retractable device of claim 1 wherein: said spring means is in a state of tension when said connecting rods is in said extended position.
Claim 8
Dependent Claim 37 words
The device of claim 5 wherein: said first end of said cylinder has a recess for receiving said eyelet when said connecting rods in said retracted position such that said eyelet is flush with said second member.
Claim 9
Dependent Claim 20 words
The retractable device of claim 1 wherein: said means for connection to said second member comprises an exterior threaded surface.
