ABSTRACT:
A suspension system for operable partitions providing for several degrees of lost motion freedom, wherein the suspension system comprises an overhead track, a series of discrete panels, and a pair of carriers for each panel to suspend the respective panels individually from the track for movement of the panels between the point of use and a storage area that is remote from the space being subdivided, with each panel having a trackway along its upper end mounting a pair of trolleys that are connected one each to the respective carriers for the panel, for movement of the panel in its plane relative to the carrier supporting it. The carriers of each panel are tandem connected and by means accommodating self fitting adjustment of the individual carriers, and the carrier trolleys are resiliently connected to the panel, whereby when an individual panel is pushed edgewise in its plane, the plane shifts in its panel relative to the carriers supporting same to redistribute the weight of the panel that is supported by such carriers to take advantage of and utilize the momentum achieved, by pushing the panel to move same relative to the carriers, to assist in moving the panel carriers, through the resilient connection of the carriers to the panel, over and across track intersections and crossovers and the like. The self adjustment accommodating tandem connection of the carriers accommodates track deviations from squared and level positions and greatly eases movement of the individual panels along parallel track. The individual panels are also connected to the carriers that support same for adjustment in their respective planes to provide for squaring of adjacent panels at their edges to accommodate deviations of track from true level due to live load variations and the like.
