Abstract
Abstract A joystick mechanism for transducing vector motion of an end of a joystick into its X and Y components including: an X-potentiometer having a body and a shaft, a bracket for mounting the body of the X-potentiometer to a surface, a Y-potentiometer having a body and a shaft, a rod connecting the shaft of the X-potentiometer to the body of the Y-potentiometer so that the shafts of the X and Y-potentiometers lie at right angles to each other, and a joystick having one end attached to the shaft of the Y-potentiometer and which is oriented such that its effective axis lies at a right angle relative thereto.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
269 words
A joystick mechanism for generating output signals corresponding to the vector position components of an input mechanical displacement, comprising: a first transducer having a first member, and a second member which is rotatable in a first direction relative to said first member, said first transducer being operative to develop a first output signal corresponding to the rotational positioning of said first member relative to said second member; a second transducer having a third member, and a fourth member which is rotatable in a second direction relative to said third member, said second transducer being operative to develop a second output signal corresponding to the rotational positioning of said third member relative to said fourth member; means for mounting said first member to a reference surface; means for connecting said third member to said second member such that said first transducer supports said second transducer and such that said first and second directions are along arcuate paths that lie in planes normal to each other; control means including an elongated shaft having one end connected to said fourth member and another end movable over an imaginary spherical surface to which orthogonal coordinates can be ascribed relative to a neutral position whereby movement of said another end to any position on said imaginary surface causes corresponding rotation of said second member relative to said first member and of said fourth member relative to said third member such that said first output signal is proportional to one coordinate of said position on said imaginary surface and said second output signal is proportional to another coordinate of said position on said imaginary surface.
Claim 2
Dependent Claim
269 words
A joystick mechanism for generating output signals corresponding to the vector position components of an input mechanical displacement, comprising: a first transducer having a first member, and a second member which is rotatable in a first direction relative to said first member, said first transducer being operative to develop a first output signal corresponding to the rotational positioning of said first member relative to said second member; a second transducer having a third member, and a fourth member which is rotatable in a second direction relative to said third member, said second transducer being operative to develop a second output signal corresponding to the rotational positioning of said third member relative to said fourth member; means for mounting said first member to a reference surface; means for connecting said third member to said second member such that said first transducer supports said second transducer and such that said first and second directions are along arcuate paths that lie in planes normal to each other; control means including an elongated shaft having one end connected to said fourth member and another end movable over an imaginary spherical surface to which orthogonal coordinates can be ascribed relative to a neutral position whereby movement of said another end to any position on said imaginary surface causes corresponding rotation of said second member relative to said first member and of said fourth member relative to said third member such that said first output signal is proportional to one coordinate of said position on said imaginary surface and said second output signal is proportional to another coordinate of said position on said imaginary surface.
