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).
