<p>A control stick having four rod-like shaft members (4, 5, 6 and 7) can be moved in the plane (X, Y) and turned, that is, three degrees of freedom. Three of the shaft members (4, 5, 6) are spherically supported in the handgrip (1) of the control stick and the base portion (3). A fourth shaft member (7) placed centrally between the three others transmits the stick motion to sensors in the base portion (all three degrees of freedom). This fourth shaft member (7) is spherically supported in the base portion and is attached to the handgrip portion (1) by means of a universal joint (22). The fourth shaft member (7) is advantageously capable of being tension-loaded by means of a tension device (24) so that the force required to operate the control stick can be adjusted.</p> |
