<p>The framing has an intermediate element (4) fixed to a panel (5) and cooperated with a displacement unit (2) associated with a fixed frame (1) to allow displacement of the panel along the frame. An opening (3) comprises through slots (6a, 6b), and an intermediate element (4) has main longitudinal wings (4a, 4b) passing via the slots. Longitudinal pads (4d, 4e) are connected to ends of the wings and cooperated with the unit. The frame is positioned entirely above or below an outer surface (Se) of the opening, so that the frame does not disclose any element protruding to outside of the opening.</p> |
