In the 1 is a perspective view of a first embodiment of a roller shutter according to the invention 1 for a façade window 2 shown. The facade window 2 , which may alternatively be designed as a facade door, is in a facade 3 a building 4 arranged. Behind the facade window 2 there is a room 5 of the building 4 , The facade window 2 essentially comprises a fixed frame 6 and one of the window frame rotatable and / or tiltable suspended window sash 7 who is in the room 5 let open in an arrow direction z. According to an embodiment variant, not shown, the window sash 7 designed as a fixed window sash. The shutter 1 is thus as a facade window roller shutter 8th educated. The shutter 1 essentially comprises a roller shutter box 9 in which a winding shaft 10 rotatable about a winding shaft axis 11 is arranged, a left guide rail 12 , a right guide rail 13 , a cover 14 and a traction device 15 which by a left band 16 and a right band 17 is formed. The cover 14 is about the tapes 16 . 17 with the winding shaft 10 connected. The winding shaft 10 is rotatable by means of a motor, not shown, or by means of a roller shutter belt, not shown, in a reeling direction w and a unwinding direction w '. With dashed lines is a vertical position 18 the right guide rail 13 of the shutter 1 indicated. Such a vertical position 18 is known from conventional roller shutters and allows the cover 14 from a rolled-up position in which it is completely in the shutter box 9 is received, in an unrolled position, in which this parallel to the window sash 7 and completely covers it. Such positions of the shutter are also possible in the roller shutter according to the invention. This goes in particular from the 2a and 2 B in which a variant of the invention roller shutter is shown. In the in the 1 illustrated roller shutter according to the invention 1 essentially one stands out of the guide rails 12 . 13 and the cover 14 formed flap 19 in a tilted position K, which is referred to as Kippstellung K90, since the flap 19 to the frame 6 or the facade 3 an opening angle 20 of 90 °. To the illustrated tilt position K90 of the flap 19 To achieve essentially two technical measures are required in which the roller shutter according to the invention differs fundamentally from conventional roller shutter for facade windows. First, the guide rails 12 . 13 not firmly fixed to the facade or the frame of the facade window, but are by a joint means 21 which is in the form of a left joint 22 and a right joint 23 is executed to a rotation axis 24 pivotable on the frame 6 of the facade window 2 arranged. Here are the joints 22 . 23 each at a lower end of the rail 25 respectively. 26 the guide rails 12 respectively. 13 and consequently also on a lower cross member 27 of the frame 6 attached. As a result of this suspension are the guide rails 12 and 13 in front of the facade window 2 in a Zuklapprichtung q and a Aufklapprichtung q 'about the axis of rotation 24 pivotable, the axis of rotation 24 parallel to the winding shaft axis 11 runs. Second, the traction means 15 , which by the mentioned bands 16 . 17 is formed, carried out so long that the flap 19 on the tapes 16 and 17 after the cover 14 completely from the winding shaft 10 is settled and exclusively between the guide rails 12 . 13 is, can be lowered into the tilted position K90. A length L15 of the traction device 15 which is in the 1 is indicated only schematically, is in the in the 1 shown embodiment about 1.5 times a length L14 of the cover 14 , For stabilization is the flap 19 still stiffened by a cross member Q, which the guide rails 12 . 13 at upper rail ends 25a and 26a combines. The cross member Q connects the guide rails 12 . 13 where the cover 14 in grooves 12a . 13a the guide rails 12 . 13 entry.

The cover 14 is made of individual slats 28 formed, which are hinged together. These slats 28 in other words, form a so-called roller shutter RP. To the tilt position K of the flap 19 to give their special function is the cover 14 as a collector 29 executed, and points on its inside 30 a collector surface 31 on, which as a reflection surface 32 is trained. By such a design of the cover 14 is it possible to have light or heat radiation 33 , which on the facade window 2 would pass by, reflect and towards the facade window 2 to steer. Thus, it allows the folding position of the shutter according to the invention 1 , the brightness in the room 5 and / or the heat radiation into the room 5 to increase. Of course, it is also provided according to the invention, backs 34 . 35 the guide rails 12 . 13 which is approximately parallel to the collector surface 31 lie, as further reflection surfaces 36 . 37 to use.
