Abstract
This invention relates to a rotatable shutter for slot ventilation through a
hollow profile of which the internal wall and external wall form a
continuous hollow chamber, characterized in that in above said hollow
chamber a shut off element (8) is mounted, which can revolve around
an axis (9) extending over the entire length of the hollow chamber,
between the open and closed positions, to which purpose said shut off
element (8) shows an oblong cavity (14) in which fits a tap (13) being
part of a disc (11) which is rotatable from outside the hollow profile.
Description
- This invention relates to a rotatable shutter for slot ventilation through a hollow profile, of which the internal wall and external wall form a continuous hollow chamber with local passages, and the external wall shows an outwards protruding cap which partially protects the passages in the external wall.
- The aim of the invention is to achieve a shutter of the said type, which is easy to operate, and allows the desired hermetic seal and a ventilation in several intermediate positions.
- In order to make this possible in accordance with the invention, in above said hollow chamber a shut off element is mounted, which can revolve around an axis extending over the entire length of the hollow chamber, between the open and closed positions, to which purpose said shut off element shows an oblong cavity in which fits a tap being part of a disc which is rotatable from outside the hollow profile.
- Still according to the invention, the above said hollow profile, at the top and internally, shows a wing extending over the entire length of this external wall and forming the above said axis around which above said shut off element snapped on this axis can revolve.
- Other details and advantages will become evident from the following description of a rotatable shutter for slot ventilation according to the invention. This description is only given as an example and does not limit the invention. The reference numbers refer to the attached figures.
- Figure 1 is a cross section of the rotatable shutter according to the invention, shown in open position;
- Figure 2 is, on a smaller scale, the same cross section, with the shutter in closed position;
- Figure 3 is a side view of the disc for operating the shutter;
- Figure 4 is a partial section according to line IV-IV in figure 3;
- Figure 5 is a side view of the device according to the invention;
- Figure 6 is a section according to line VI-VI in figure 5.
-
- The rotatable shutter shown in these figures is mounted here in a hollow profile composed of an
internal wall 1 with local grate shapedpassages 2 and an external wall 3 - 3' with acontinuous passage 4 and ascreening cap 5. In the usual way, theinternal wall 1 and the external walls 3 - 3' are connected byplastic profiles 6 ensuring the interruption of the thermal bridge. Sidelong, theinternal wall 1 and the external walls 3 - 3' join twohead walls 7, one of which is shown in side view in figure 6. These parts actually form the housing in which the shutter is mounted. - The rotatable shutter according to the invention is formed by a shut off
element 8 which can revolve around anaxis 9 extending over the entire length. Theaxis 9 is part of the profile forming theexternal wall 3. - The shut off
element 8 which is made of a plastic material, may be slided over theaxis 9 or snapped to it. To that purpose, the shut offelement 8 shows a hollow chamber 8' extending over almost 270 °, and the element consists of a composite material so that the lip 8'', which in closed position is contacting thebuffer edge 10 belonging to the external wall 3', and consisting of a somewhat elastic material, may be pressed sealingly against thisbuffer edge 10. - The rotation from the inside of the shut off
element 8 is ensured by arotatable disc 11 with handle 15 (figures 1-4). Therotatable disc 11 sidelong has atap 13 which fits in anoblong cavity 14 belonging to the shut offelement 8. The rotation of thedisc 11 brings the shut offelement 8 alternately in the open and closed position. The open position is shown in figure 1, while the closed position is shown in figure 2. - The rotation by the user of the shut off
element 8 is obtained by acting on the handle 15 (figures 5, 6) withspring finger 16. Thelever 15 is spring-mounted between twoarms 17 belonging to thedisc 11. Because a protrusion 16' exists at the extremity of thespring fingers 16, it is possible to block the shut offelement 8 in several positions between the open and closed position. Indeed, upon rotation of thedisc 11, this protrusion 16' moves overteeth 18 on a part of thehead wall 7 located to the same side of the shut off element as thedisc 11. - From the above description of the shutter according to the invention, it is shown that an excellent ventilation can be realised using technically simple and reliable means.
Claims (5)
