According to a particularly advantageous embodiment, said fixed member can be non-positive be connected to the upper end of the vertical guides that guide the adjustment of the screen serve according to the roller shutter.

Instead of using a curtain or roller shutter with two independent screens, the Means for relative adjustment of the two screens A curtain can be used in which the two screens are made of transparent material one below the other connected by opaque bands = the vertical adjustment of one of the screens thus obtained in relation to the other (or the two screens one in relation to the other) leads to the inclination of the opaque Ribbons and for regulating or "setting the air or the light that or" that through the Shutters through »

Eb it is assumed that the shields βαβ exist from £ öhbroohenen bands. Xn utidurohbroohener Line an eehematiaeh the zones indicated at where the screens are not broken, and in broken line the broken zones. It is known that in the extreme aoroll or Abwiokelstellung (Fig. 1), in which the bar 2 is symmetrical in relation to the axial horizontal plane of the drum vex * - runs, facing the broken zones.

In-call over an arch of the cylinder, for example by about 180 °, and allow free swinging of the strips 16, 17, which tend to occupy the permissible position furthest down due to the force of gravity.

In the maximum unwinding or unrolling position (Figo3) the strips 16, 17 are at one end of the path in relation to the drum 11 and the screens 14 »lij hang from the surface lines very close to the drum hernbo whose bands are divided into openings. If, starting from this position, the drum 11 is turned in the direction of the arrow in order to wind it up, the screen 14 is raised, while the screen 15 remains practically immobile, since the hanging strips 16, 17 remain in the lower position as a result of gravity 18 shift the length of the openings 19 until they reach the ends opposite these openings (position according to Pig. 4) At this moment the roller shutter has reached the closed position * If the winding movement is continued, the two screens are therefore wound up at the same time , namely the screen 14 somewhat faster than the screen 15 »as in the present example, and this is done in turn so that the load crossbars of the z white screens are in the completely raised position of the roller shutter against each other.

It will be noted that the screen 14 is preferably a The screen is on the outer edge of the opening, for example Window opening, is performed. The guidance of the screen 14 and possibly also the inner one

Screen 15 can be in vertical (not shown) Slideways take place on the Öhasois or «, The frame of the lockable opening is required *

In Pig * 5 and 6, the drum is marked with 21 and provided with a fastening strip 22, which is fastened by screws 23 to fasten the suspension strap 24 made of steel or other material, as a horizontal rod

25 on which the screen 26 is suspended, while the other screen 2 '? (which is preferably located at the same point on the outside of the opening) j is suspended from a rod 28 which is carried by the movable ring 29, which is loosely mounted on the drum 21. You Baader step between the movable rod 28 and the drum 21 in the recessed outer spaces sv / see the hangers 29 through =

In the completely unwound, rolled position (FIG. 5), the rod 25 is a certain amount under the drum 21 ₉ so that it corresponds, for example, to a closed position of the roller shutter. When the drum is rotated in the winding direction shown by the arrows, the screen becomes

26 initially raised to the position of Fig. (opening of the roller shutter). Soiann allows the continuation de3 Aufwickeins the simultaneous lifting of the two screens; the screen 27 "rolled up on the outside of the other" rises with something greater speed »

It should be noted that in this pail the relative

Positions of the umbrellas at the beginning of the winding up in the advance of the winding up causes the opposite direction and are therefore compensable, instead of adding themselves in such a way that the maximum denivelling, doh. Deviation from the horizontal position or conformity of the load bars can be reduced in the lower position of the roller shutter.

Figures 7 and 8 show an equivalent device. The drum is denoted by 31 and provided with a fastening strip 32 which passes through Screws 33 for hanging the screen 34 attached is, while the screen 35 is hung on bands, which pass through the openings 37 in the wall of the drum and sit on rollers 38 Wind up the frictional connection with the interior of the drum of the drive shaft 39 and a circular arc cam 40 is connected, which is able with its ends to the radial rib 41 of the profile to abut the tubular drum.

In the maximally developed position (I ¹ Ig. 7), the axis 39 is in its extreme position in relation to the drum 31. In this position, for example, an open position of the roller shutter is reached. If the axis 39 is rotated in the winding direction, which is shown by the arrows, the drum 31 remains immobile until the cam 40 assumes its extreme position in relation to the drum, which in this sense when it hits the inner rib 41 of the drum (position after Fig. 8) so opposite _r that the screen 35 only when

Adjusting the Kollaöenß flteigt in the closed position to ^"v ,, the ON position of Fig * 6 starting, the rotation takes öar Achae 39 through the perching 40, the drum 31 and the two screens are rolled up simultaneously; the screen 34 is actually wound up somewhat more narrowly in relation to the screen 35 "a reverse relative movement of the closing movement leads at the beginning of the winding process" there is, therefore, again a compensation for the two relative movements "

It is clear that the drive, for example driving the drum, can be easily implemented in various ways by hitting the drive shaft. drum is connected is driven to axially _c but for example by a thread of the axis "that it with the squatting comes into contact with the axis ₉ of the kraftschliissig at the end of a certain number of BAW axis. This arrangement can be preferred if the inside dimensions of the drum are too. ₉ is low in order to achieve sufficient winding of the suspension tapes with a rope amount of one revolution.
