ABSTRACT:
A mechanical linkage system for generating a straight line and useful as a guidance mechanism utilizing links which do not cross-over in the motion generated. A rigid bellcrank member has a centerpivot connection to a first suspension link, a second pivot connection to a substantially linear guide mechanism, and a third pivot connection to an output point, the dimensions of said link, the distance between said center pivot connection and said guide mechanism, and between said center pivot and said output point are generally equal. The guide mechanism can be a linear slide or a straight line linkage.
