Abstract
Abstract In a control device of the "joystick" type in which movement of a single control lever is resolved into two orthogonal components, each component is represented by movement of one of a pair of pivoting members. Each such pivoting member has a respective coupling member mounted thereon for angular movement relative thereto about an axis perpendicular to the axis of the corresponding pivoting member. The two coupling members are connected to the control member so as to be restrained against relative translational movement.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
90 words
A control device comprising a pair of pivoting members mounted in a housing for angular movement about mutually orthogonal axes, each pivoting member having a respective coupling member mounted thereon for angular movement relative thereto about an axis perpendicular to the axis of the corresponding pivoting member, and a common member connected to each of said coupling members so as to be restrained against relative translational movement in a plane containing the axis of pivotal movement of the corresponding coupling member, said four axes having a common point of intersection.
Claim 2
Dependent Claim
90 words
A control device comprising a pair of pivoting members mounted in a housing for angular movement about mutually orthogonal axes, each pivoting member having a respective coupling member mounted thereon for angular movement relative thereto about an axis perpendicular to the axis of the corresponding pivoting member, and a common member connected to each of said coupling members so as to be restrained against relative translational movement in a plane containing the axis of pivotal movement of the corresponding coupling member, said four axes having a common point of intersection.
Claim 3
Dependent Claim
69 words
A control device according to claim 1, wherein each of the pivoting members comprises a rectangular frame mounted for pivotal movement about an axis extending through and perpendicular to its end, and each of the coupling members comprising a respective U-shaped member having the ends of its limbs pivotally connected to the sides of the corresponding pivoting member and a centrally disposed socket through which the common member projects.
Claim 4
Dependent Claim
26 words
A control device according to claim 2, wherein the common member is a sliding fit in the socket of at least one of the coupling members.
Claim 5
Dependent Claim
43 words
A control device according to claim 2, wherein the sides of each pivoting member comprise respective E-shaped members with the ends of the frame attached to the end limbs of each E-shaped and the coupling members pivotally connected to the centre limbs thereof.
Claim 6
Dependent Claim
22 words
A control device according to claim 1, including means for resiliently biasing each of the pivoting members into respective predetermined angular orientations.
Claim 7
Dependent Claim
51 words
A control device according to claim 5, wherein the biasing means for each pivoting member comprises a cranked lever having a edge adapted to engage with at least one of a pair of projections on the pivoting member and a spring arranged to bias the lever into engagement with the projections.
Claim 8
Dependent Claim
34 words
A control device according to claim 1, wherein each pivoting member is connected to the wiper of a respective potentiometer, the resistance winding of which is coupled to a housing for the control device.
Claim 9
Dependent Claim
31 words
A control device according to claim 6, wherein the resistance winding of each potentiometer is coupled to the housing via means for varying the angular positions thereof relative to the housing.
