ABSTRACT:
The present invention relates to a shutter device comprising a number of shielding slats and operating means, by means of which the shielding slats are displaceable from a position substantially removed from the shielding surface to individual positions distributed over said surface, and pivotable round their longitudinal axis for setting in different angular positions to provide the desired shielding of a surface. The device further comprises two guide rails carrying a number of runner units provided in pairwise arrangement in order to support the two ends of the respective shielding slat in such a manner, that the shielding slats are pivotable relative to the runner units and retainable in said individual positions distributed over the shielding surface. According to the invention the device is provided with retaining means comprising supporting organs on each runner unit and stops provided in each one of the guide rails which stops are so situated in the transverse direction of the respective guide rail that each one of them is in the path of movement of one of the individually placed supporting organs of the runner units and so situated in the longitudinal direction of the respective guide rail that each slat is in its predetermined individual position when the respective supporting organ is resting on the corresponding stop.
