Abstract: A profiled unit (10) for a shower partition door (S) is mounted for rotation about an off-center vertical axis (A) and accommodates, in longitudinal grooves (12, 14) on either side, partial leaves (22, 24) whose position relative to each other is adjustable in at least two directions. At the front and/or rear, flat elements (30, 38) are lockable into a profiled element (11), whose ends accommodate pivot bearings (26, 28) between which the profiled unit (10) can be raised or lowered even during its rotation and can be locked in position in at least one door position. An adjustable and lockable supporting plate (50) sits below the bottom pivot bearing (26). Above this, the door rests on a preloadable spring assembly (F) that includes a compression spring (67) that can be contracted and released in order to lower or raise said door (S), respectively.
