1. A door for an elevator comprising a plurality of horizontally sliding door panels of generally the same width, and a multiple node scissors linkage for controlling the simultaneous movement of the panels between open and closed positions, the panels having their left and right vertical edges respectively substantially aligned and registered with one another when the panels lie alongside one another in an open position and having right and left edges of proximal panels adjacent one another when the panels are in a closed position, said linkage including long links having pivots at their operative ends and at their operative centers, said long links having lengths greater than the width of the door panels and being arranged such that in the closed position of the panels, said long links are substantially inclined from a horizontal plane, said links being supported by brackets extending from respective panels, said brackets being arranged to support said links in vertical planes that are parallel to said panels and when the panels are in an open position lie alongside said panels in a zone substantially between imaginary vertical planes at the edges of the panels and perpendicular to the panels.
