An anti-float system for operable partitions in a movable wall system. The anti-float system includes first and second camming assemblies, each including a trolley camming surface, cooperatively positioned along the operable partition track. Preferably both of the trolley camming surfaces are spring biased to camming positions where they define a passageway through which a portion of the trolley passes when the trolley moves along the track. The passageway is narrower than the width of the trolley portion. When the trolley portion enters the passageway while traveling in the wall extending direction, the trolley portion engages the trolley camming surfaces and forces the surfaces outward from their camming positions against a resistance provided by the biasing springs in order for the trolley to pass. The camming assemblies are also movable from a camming alignment to a retracted alignment when the trolley portion travels in the wall stacking direction through the passageway. |
