Mechanically-linked side stick controllers with isolated pitch and roll control movement
First Claim
1. Mechanically-linked control stick mechanisms for isolating movement in two axes, comprising:
- first and second control stick mechanisms, each comprising;
a hand-operated control member movable to swing about two axes of rotation;
a first lever member on said control member which moves in response to swinging movement of said control member about the first axis of rotation; and
a reciprocating member having a first portion pivotally attached to said control member at a location spaced from the second axis of rotation and having an elongated second portion longitudinally movable along a line of reciprocation substantially co-axial with said first axis of rotation in response to swinging movement of said control member about the second axis of rotation;
wherein movement of each said first lever member effecting operation of a separate first control sensor and movement of each said reciprocating member effecting operation of a separate second control sensor, each said control sensor including means for translating mechanical motion into an electrical signal; and
mechanical linkage between said first and second control stick mechanisms for transferring movement of the control member of one mechanism to the control member of the other, said mechanical linkage including override means for allowing movement of either one of said first and second control stick mechanisms and its separate control sensors in the even that the other control stick mechanism is mechanically stuck or inoperable.

Abstract
Side stick controllers with isolated pitch and roll control movement may be mechanically linked. A control stick mechanism includes a hand-operated control member (10, 10'"'"') movable to swing about two axes of rotation (12, 14). A first lever member (16, 16'"'"') on the control member (10, 10'"'"') moves in response to swinging movement of the control member (10, 10'"'"') about a first axis of rotation (12). A reciprocating member (20) has a first portion (22) pivotally attached to the control member (10, 10'"'"') at a location (24) spaced from the second axis of rotation (14). The reciprocating member (20) has an elongated second portion (26) axially movable along a line of reciprocation substantially co-axial with the first axis of rotation (12) in response to swinging movement of the control member (10, 10'"'"') about the second axis of rotation (14). Movement of the first lever member (16, 16'"'"') effects operation of a first control sensor (44, 46) and movement of the reciprocating member (20) effects operation of a second control sensor (40, 42).
