Abstract:
A self-centering device, comprisinga) a first plate; b) a second plate rotatably mounted to the first plate and free to rotate about an axis of rotation to at least two spaced stable positions, c) a first post mounted on the first plate at the first stable position; d) a second post mounted on the first plate at the second stable position; e) a flexible belt entrained about the first and second posts and defining a circumscribed space; and f) a force transferring element projecting from the second plate into the circumscribed space and movable about the axis with the second plate when an external rotatable force is applied to the second plate such as to stretch the flexible belt, the flexible belt thereby applying forces to move the second plate to either the first or the second stable position when the external force is removed.
