ABSTRACT:
A device for displacing a member, primarily a stage for optical instruments, in arbitrary directions in one and the same plane. The member is basically square, and its respective corners are connected to the middle of each side of a surrounding square frame which is supported on one hand by two substantially vertical rods carried by a base, said rods being attached to two diagonally opposite corners of the frame, and on the other hand by additionally two substantially vertical rods, which latter are suspended above the frame and are attached to the remaining opposite corners of the frame. The member is capable of being positively displaced by means of two articulate rods disposed in different directions in the plane of displacement of the member substantially orthogonal to each other. The member is prevented from rotating around an axis orthogonal to the plane of displacement by means of two further rods, both of which are attached to the member and to a rigid component connected to the base by means of a hinge joint.
