Abstract: The present invention involves a latch mechanism and method that prevents the leading operable wall panel of an operable wall panel system from moving out of alignment with the track of a track and trolley system as the lead operable wall panel unfolds and extends from a stacked orientation to a straightened orientation. The latch mechanism includes a catch member to catch a latch pin depending down from the trolley of the track and trolley system. When the catch member catches the latch pin, a resilient biasing member of the latch mechanism operates to lock the latch mechanism about the latch pin. As a result, the lead operable wall panel is locked into a straightened orientation.

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.

Abstract: The present invention involves a flattener apparatus for a movable wall system that eliminates misalignment, drifting and binding of the wall panels in the extended wall-forming position. The flattener apparatus holds movable wall panels of a movable wall panel system in an extended aligned orientation along the length of the track thereof. The flattener apparatus includes a flattener member extending along a portion of the track. The flattener member has a base flange attached at the bottom of the track assembly and a relatively transverse guide flange depending vertically downward from the base flange. A sealing sweep extends along a portion of the top end of the movable wall panels. A guide pin protrudes from the top end of the movable wall panels. The sealing sweep and the guide pin define opposite sides of a vertical channel for receiving the guide flange portion of the flattener member as the wall panels are extended toward the portion of the track having the flattener member attached.
