<p>The invention relates to a transparent air volume separator meant to separate air masses for saving caloric energy and separating odours. According to the invention, the separator comprises a rod employed to attach a coloured transparent or semi-transparent foil (2) to the car ceiling or to the ceiling of a building, said foil being wound on a roll (5) and having at its ends some caps (3 and 3'), the extremities of which contain a moulded or screwed piece (4) used for fastening the device inside a roll attaching module (6), introduced into a modular clamp (28) which attaches the entire device to the internal lining of the car body, so that, the plastic moulded ends of the cap (3), by using a helical spring (13) fixed at one end within a casette (14), allow the decrease of the total length, in order to achieve fastening by means of the piece (4) entering the module (6), where the first cap (3), on the right, has a moulded or screwed blade (16), with a view to overlapping an attached piece (17), when the helical spring (13) is released, so as to block the unwinding of the foil (2) in the dismounted state of the device, and a mechanism with a prestressed spring has a shaft (18) to which the blocking piece (17) is screwed, the mechanism having some protuberances (19) on said shaft (18) allowing it to be attached to various materials and a metal safety element (22) for blocking the shaft in one direction, in the other direction the blocking being ensured by the specific shape of some wheels (20 and 21), on said mechanism there being mounted a thin metal jacket (23) which is tightened to clamp the foil (2) by means of some small screws, the foil (2) coming out through the caps (3 and 3'), through some slots (24), in the selected embodiment a fastening system (26) being clamped by screwing onto a thin metal sheet cover (27) which, in its turn, is clamped by small screws to the metal jacket (23).</p> |
