Abstract: Presented is a two-shell telescopic element for a movable partition that has a wall section and a horizontally extendable telescoping part. The cover panels of the telescoping part are disposed on the telescoping part in transversally movable fashion to their principal plane. With extended telescoping part, the cover panels run out formt he overlapping area formed with the cover panels of the wall section and can be brought into an end position aligning with the cover panels of the wall section, transversally to the running planes, by an actuating mechanism.

Abstract: Presented is a two-shell telescopic element of a movable partition containing (holding) two external cover panels on the supporting frame of a wall section, between which, at the upper and/or lower edge, are guided packing strips, and that are extendable out toward the ceiling and/or the floor. An edge-side telescoping part has a vertical edge strut to which are also attached cover panels that overlap the cover panels of the wall section, or that continue in surface-flush fashion. The packing strips have an edge section projecting inwardly between the cover panels of the telescoping part, said edge section being horizontally displaceable together with the telescoping part. In order to achieve an improved noise damping, provided are intermediate panels that engage behind the cover panels of the wall section and of the telescoping part.
