Abstract
In order to provide a simple design of ventilation device which has a relatively open aperture of pleasing aesthetic appearance, there is provided a face 2 for facing into a room, the face including an aperture 3. Three closure parts 5 are provided for closing the aperture 3. The closure parts 5 are rotatably mounted adjacent to the aperture 3 about pivots 9 located around the periphery of the aperture. A drive means is provided for moving the closure parts between an open position and a closed position. A suitable fan 6 can be provided for drawing air through the aperture when the closure parts are in the open position. In a first aspect of the invention, the closure parts 5 each comprise closures surfaces having edges, the edges abutting one another in the closed position. In a second aspect of the invention, there is drive member 12 for contacting a drive part 11 of a closure part 5, the drive part 11 being located close to the pivot 9. In a third aspect of the invention, the drive means 12 is configured to act on a drive part 11 of each closure part, the pivot 9 and the drive part 11 being mounted on the same side of the closure part 5.
