Abstract
A Sarrus linkage is a type of folding linkage or structure in which two opposed links are connected by two sets of connecting links, each of which sets includes two separate links. The links of such a linkage are hinged together in such a manner that the entire linkage will fold and unfold as any part of the linkage is moved with respect to the remainder of the linkage. By providing a control link which is pivotally connected to one of the opposed links and a motion transmitting link pivotally connected to the control link and to one of the links of one of the sets, a folding structure can be obtained which can be employed for a variety of useful purposes. Best results are obtained when two of the motion transmitting links are employed, one of the motion transmitting links being pivotally connected between a link of one of the sets and the control link and the other of the motion transmitting means being connected between a link of the other of the sets and the control link.
