Abstract
A parallel translation mechanism, when connected between a first element and a second element, maintains the relative direction between the two elements constant when one of those elements is moved relative to the other. The mechanism is in part formed by first and second rigid elongated members which are pivotally connected together and are pivotally connected by the end of the first elongated member to one of the elements. A first portion of an extendable member is connected between the one of the elements and the second elongated member, and a second portion is connected between the other element and the second elongated member. The other element is also pivotally connected to a position on the second elongated member. The three members of the mechanism are connected together in such a fashion that the described relative movement between the two elements is obtained. The mechanism has particular application to forklift vehicles.
