Abstract

See full text

A mechanism suitable for a control lever such as a joy stick has two mutually perpendicular axes of rotation which provide movement in two planes. At least two close wound coil springs form a set and a set of springs is provided for each plane. The springs deflect when a force is applied on the control lever but return to a center position when the force is released. The mechanism avoids the use of shafts.
