Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
181 words
Hand control apparatus for the piloting of an aircraft by an-operator lacking use of his legs, the aircraft having means for controlling its course, means for controlling a throttle, means for heating a carburetor, a conventional joy-stick, and left and right brakes, said apparatus comprising a handle, means supporting said handle for three independent movements and means individually responsive to a respective movement of the handle for controlling the course control means, the throttle control means, and the carburetor heating means, hand-operated switch means carried by said handle for control of further elements of the aircraft, a second joy-stick, means coupled to said second joy stick for respectively operating the right and left brakes in accordance with the positioning of the second joy stick and a common support element on which said handle, said brake operating means and the means controlling the course control means are so assembled in operative position relative to one another and mutually coupled together for interrelated operation to allow complete manual control by the operator of the handle, and joy-sticks during respective flight and ground operations.
Claim 2
Dependent Claim
181 words
Hand control apparatus for the piloting of an aircraft by an-operator lacking use of his legs, the aircraft having means for controlling its course, means for controlling a throttle, means for heating a carburetor, a conventional joy-stick, and left and right brakes, said apparatus comprising a handle, means supporting said handle for three independent movements and means individually responsive to a respective movement of the handle for controlling the course control means, the throttle control means, and the carburetor heating means, hand-operated switch means carried by said handle for control of further elements of the aircraft, a second joy-stick, means coupled to said second joy stick for respectively operating the right and left brakes in accordance with the positioning of the second joy stick and a common support element on which said handle, said brake operating means and the means controlling the course control means are so assembled in operative position relative to one another and mutually coupled together for interrelated operation to allow complete manual control by the operator of the handle, and joy-sticks during respective flight and ground operations.
Claim 3
Dependent Claim
36 words
Apparatus as claimed in claim 1 wherein said handle is supported by the supporting means to effect said three movements respectively consisting of forward and rearward movement, lateral movement, and rotational movement about its own axis.
Claim 4
Dependent Claim
26 words
Apparatus as claimed in claim 1 wherein said switch means on said handle include three buttons respectively controlling operation of the alternator, flaps and fuel pump.
Claim 5
Dependent Claim
35 words
Apparatus as claimed in claim 1 wherein said means for controlling the course control means includes operating elements having end of travel positions which respectively act on the brake operating means for actuating the same.
Claim 6
Dependent Claim
38 words
Apparatus as claimed in claim 1 comprising means coupled to the conventional joy stick for controlling the trim tab of the aircraft by rotation of said conventional joy stick about the longitudinal axis of said conventional joy stick.
Claim 7
Dependent Claim
192 words
Apparatus as claimed in claim 1, said support element comprising a lower plate, said means controlling the course control means comprising a steering rocking lever rotatably mounted on said plate, two adjustable rods coupled to said steering lever, two rudder bars coupled to said rods and operated thereby, a control rod coupled to said steering lever to operate said steering lever, a vertical post supported in said plate for horizontal rotatable movement and coupled at the lower end thereof to said control rod, a second plate mounted on said first plate at a location thereabove, said second joy-stick being mounted on said first plate for longitudinal and transverse oscillatory movement, means on said second plate engaging the second joy stick to hold the same in a biassed inoperative centered position, two cables coupled to said second joy-stick to follow the movement thereof, two arms pivotably mounted on said second plate and connected to a respective one of said cables and controlling operation of the brakes, an end of travel beam pivotably mounted on said second plate and including two abutments for said two arms and two further abutments for said rudder bars.
Claim 8
Dependent Claim
101 words
Apparatus as claimed in claim 6 comprising a bracket means supporting said handle including a tubular arm, a ring rotatable in fixed structure, and slidably receiving said tubular arm, a fork joint in said tubular arm and coupled to said vertical post at the upper end thereof, a vertical arm secured to said tubular arm, a socket mounted on said vertical arm, and a longitudinal arm carrying said handle and rotatable in said socket, said handle being mounted on said longitudinal arm for rotation about the longitudinal axis of said handle, said switch means comprising control buttons mounted on said handle.
Claim 9
Dependent Claim
131 words
Apparatus as claimed in claim 3 wherein said button for control of said flaps comprises a switch having three positions corresponding to in, out and central flap positions, three warning lamps coupled to said switch, three non-return diodes connected to said switch, a first switch contact for the end of the inwards travel, a second switch contact for the end of outwards travel, a third switch contact closed in the central position of the three position switch, an inlet relay energized through said third switch contact when the flaps are slightly more than half way out, said second switch contact being closed in the central position of the three position switch, and an outlet relay energized through said second switch contact when the flaps are slightly more than half way in.
Claim 10
Dependent Claim
89 words
Apparatus as claimed in claim 5 wherein said conventional joy-stick includes a rotatable handle, said means coupled to the joy-stick for controlling the trib tab comprising a screw integral with the handle of the conventional joy-stick, a roller threaded on said screw, a slide, lugs coupled to said screw and said slide to drive the latter for control of the trim tab, a sleeve receiving said roller and integral with said handle of the joy-stick and a key on said slide slidably mounted in a groove in said sleeve.
