Lamellar blind

摘要

The invention takes as its departure point lamellar blinds having lamellae which can pivot about a vertical axis. The main endeavour of the invention is that the blind should not only alter the influence of light and sun, but, in addition, should also be able to contribute to an air-conditioning of the associated room. This is achieved by one or more air ducts which run parallel to the lamellae and have an air-inflow opening at the bottom and an outflow opening at the top. Furthermore, however, the air ducts are translucent, at least in some areas, such that the air located in the duct can heat up.
