<p>A shutter, to be fixed to the substructure of a façade, having several blades (1-5), the latter arranged in parallel with a gap between each blade and the next. Each blade can be fixed in place by means of an upper fixing extremity to the façade substructure and has a blade section (1) running diagonal to the fixing extremity, the blade section (1) continues into a lower fixing extremity which is made up of a lower slot (3) open in the direction of the façade substructure. The latter has a somewhat greater than semi-hemispherically-shaped cross section and faces an upper slot (2) which forms the upper fixing extremity of the respective inferior blade and is open in the direction of the lower slot of the respective upper blade. In order to utilize the same blades for different shutter constructed, the invention provides that the upper slot (2) of each blade likewise has a somewhat greater than half-hemispherically-shaped cross section and forms part of a pivot bearing unit around which the blade (1-5) can be swung.</p> |
