ABSTRACT:
A joystick includes a handle, a base shaft having opposite upper and lower ends, and a curvilinear housing. The handle is mounted on the upper end of the base shaft. The lower end of the base shaft is mounted into the curvilinear housing. The curvilinear housing has an outer curvilinear surface formed so as to include at least a clamp support portion of a zone of a spheroid between two generally horizontal and parallel planes. The zone includes a portion of the spheroid having the maximum circumference of the spheroid so that the curvilinear housing may be braced by clamped support of the portion. A releasable clamp having at least two cooperating clamp members is releasably mountable by releasable fasteners onto the clamp support portion along a clamp-member interface so as to support and clamp therebetween the portion of the spheroid having the maximum circumference of the spheroid.
