The two stiles (4, 6) are attached hingingly (at 18, 20) to a sliderail (16) on which the fastening points (18, 20) for the stiles (4, 6) are movable steplessly. One end (36) of a control rod (34) is arranged hingingly but not movably on the first stile (4) and its other end (38) is arranged hingingly but not movably on the sliderail (16). |
