ABSTRACT:
A mechanism is disclosed to provide pivotal motion between two movable members. The mechanism includes a hemispherical yoke connected to one of the movable members. A center support is connected to the remaining movable member and is nested within the yoke and spaced apart therefrom. A set of four radially projecting torsion bars are connected to the yoke and center support. The torsion bars are substantially coplanar and define a cross-shaped configuration in plan. Four braces are provided to interconnect adjacent torsion bars. Preferably, each of the torsion bars is surrounded by a tubular segment which is affixed to the radially outer end of the torsion bars. Preferably the radially inner portion of the torsion bar is supported by a rotatable bearing. The subject mechanism is low in profile, easy to mount and dismount, and provides a degree of elasticity in the vertical axis.
