Position changing system

Abstract

A position control system is disclosed that replaces a parallelogram or quadrilateral movement system with greater efficiency, economy, stability and utility by eliminating one of the four links and providing a non-linear path to be followed. This system includes a dynamic triangular mechanism for movement from a first position to at least a second position, with at least three (3) link members interconnected by pivots with a first base link member defining a non-linear path, said first base link member having a fixed base pivot and a follower pivot that moves along the non-linear path, a second fixed length support link member pivotally connected to the fixed base pivot, and a third follower link member pivotally connected to, and located between, the follower pivot and a connector pivot, wherein the follower link member is adapted for following the non-linear path, thereby creating a virtual triangle defined by the three link members while the follower pivot, fixed base pivot and the connector pivot interconnect the first base link member, the second fixed length support link member and the third follower link member.
