Abstract
An inverted trolley assembly mounted in an upper channel of a movable wall panel. The inverted trolley includes an elongated trolley carrier having a centrally attached trolley block and a bore at each end to receive the axle of a roller assembly. Each roller assembly includes spacers to center the roller on the axles. The inverted trolley is connectable to a track mounted trolley, preferably by a threaded hole which receives a pendant bolt from the track mounted trolley. The inverted trolley is installed within a channel at the upper end of the wall panel with the rollers engaging the wall panel top frame thus supporting the wall panel. The panel top frame includes a slot through which connection to the track mounted trolley is made. The assembly also includes a trolley retainer which limits the range of motion of the inverted trolley.
