摘要

The chassis (1) has a door frame (2) and two adjacent openings (3), where each opening includes a central post (4) and a lateral post (5). A sliding sash is mounted on one of the openings, so as to slide between a closed position in which the central posts extend opposite to each other, and an open position in which the central posts are offset with respect to each other. The central posts are coupled to each other in a lifting direction in the closed position of the opening, where the central posts are coupled with each other by a coupling unit.
