Abstract:

A vertical movement accommodating apparatus for use with a wall panel includes a cap mounted on a ceiling structure of a room, and a support assembly mounted on a top edge of the wall panel and at least partially disposed within the cap for vertical movement with respect to the cap. The cap is a U-shaped member opening down. The support assembly includes an upper rail, a lower rail, and a truss assembly interconnecting the upper and lower rails. A sealing member is disposed between the upper rail and the cap to provide a sound reducing seal therebetween. The lower rail defines a channel in which a roller mounted on the upper edge of the wall panel is allowed to roll in the longitudinal direction.
