This invention provides an improvement in a control stick (e.g., joystick, side-stick, etc.) (20) adapted to control the movement of an object (e.g., an airfoil surface). The improvement includes: a support (21); an intermediately-pivoted upper member (23) mounted on the support, the upper member having an upper portion (24), and lower portion (25); an intermediate member (26) having an upper portion pivotally connected to the upper member lower portion, and having a lower portion; and a lower member (29) having a lower portion pivotally mounted on the support, and having an upper portion; and wherein the intermediate member lower portion is movably mounted on the lower member upper portion such that pivotal movement of the upper member upper portion relative to the support will produce pivotal movement of the intermediate and lower members relative to the support; and a resilient member (31) arranged to bias the direction of relative movement between the intermediate and lower members. The various pivotal connections may be provided by gimbals such that the various members arc mounted for compound pivotal movement about two mutually-perpendicular axes.

What is claimed is: 1. In a control stick mounted on a support and adapted to control the movement of an object, the improvement comprising:a support;a linkage for mounting a handle on said support for selective compound pivotal movement about two mutually-perpendicular axes to provide an input to said control stick, said linkage including:a first gimbal mounted on said support;an upper member mounted on said first gimbal, said upper member having a handle arranged above said first gimbal, and having a lower portion arranged below said first gimbal;an intermediate member;a second gimbal connecting said upper and intermediate members; anda lower member, one of said intermediate and lower members being movably mounted on the other of said intermediate and lower members to permit relative movement therebetween when said handle is moved relative to said support;a third gimbal connecting said lower member to said support; anda resilient member arranged to bias the direction of relative movement between said intermediate and lower members;whereby said handle may be grasped and selectively moved relative to said support to provide an input to said linkage.
