Prior art roller blind devices reduce the window surface area. The aim of the invention is to further develop a prior art roller blind device in order to obtain a simple, inexpensive and compact design that reduces the incidence of light only minimally. To this end, the invention provides that a cord reel is connected to the fabric shaft in a rotationally fixed manner while being coaxial to said fabric shaft and located in the extension thereof, and the free end of the cord that can be wound on the reel is connected to the pull rod via a cord diverter. When the fabric is pulled from the fabric shaft, the cord is wound on the cord reel and vice versa. A spring device is provided over the course of the cord in order to adapt the cord to the varying winding state of the fabric shaft and cord reel.
CROSS-REFERENCES TO RELATED APPLICATIONS This application is a continuation of International Application No. PCT/EP2003/005383, filed May 23, 2003, the contents of which are here incorporated by reference in their entirety. The benefits of 35 USC Section 120 are here claimed.
TECHNICAL FIELD The invention relates to a roller blind device as well as to a pane of insulating glass provided with such a roller blind device and to a correspondingly equipped window.
BACKGROUND OF THE INVENTION The simplest kind of such roller blind devices are, e.g., the known bolt spring rollers or snap rollers. In these devices a torsional spring is arranged in the fabric shaft and an engagement mechanism for different roll-off lengths of the fabric is provided. These roller blinds require a significant amount of force for operation and frequently snap upward in an undesired manner. In addition, roller blinds with cord tensioning devices are known. In these instances the cord is rolled up onto a second shaft. The cord shaft is driven by torsional spring in the cord shaft. Even these devices require a great amount of force and exert a heavy load on the structural components.
BRIEF DESCRIPTION OF THE DRAWINGS A few embodiments of the invention are described in detail in the following, with reference made to the accompanying drawings.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 shows a frame 2 into which a roller blind device in accordance with the invention is integrated. Frame 2 consists of lower frame part 4 and upper frame part 5. Furthermore, guide slot 3 can be recognized. Frame 2 preferably consists of sheet-metal profiles or plastic profiles formed in such a manner that after assembly they enclose the mechanism, shown in the following in detail. Guide slot 3, in which the fabric and the pull rod move in a guided fashion, remains on the inside of frame 2.
Fabric shaft 7 itself is best recognized in FIG. 5, which shows a view in accordance with FIG. 4 but without fabric 6 to be wound. For the rest, the description of FIGS. 2�4 can be referred to for the description of FIG. 5. Clip holders 11 for receiving fabric shaft 7 are also shown, in particular, in FIGS. 4 and 5.
FIG. 6 shows a sectional view of FIG. 4 in which the guidance of fabric 6 as well as the guidance of pull cords 15, 16 are shown. In order to improve the clarity, the position of the cross section is not specific. It can be gathered from FIG. 6 that fabric 6 is wound onto fabric shaft 7 and is deflected downward (to the right in FIG. 6) via diverter shaft 8. Furthermore, FIG. 6 shows cord reel 9 on which pull cord 15, 16 is wound. Finally, FIG. 6 shows pull rod 12 consisting of two cylindrical, parallel and adjacent tubes around which fabric 6 is wound in the form of an �8� and between which it is clamped in. The two components (cylindrical sleeves) of pull rod 9 are held together by the already-described structural parts shown in FIG. 10 for cord diversion and pull rod connection. As has already been described above, a U-shaped profile is set over the cylindrical components of the pull rod and over the wound fabric in order to prevent a tipping over of the pull rod. It can be gathered from FIG. 6 that the effect of fabric diverter shaft 8 is that fabric 6 always lies on the same plane.
FIGS. 8�11 were already referred to in the description of FIGS. 1�6. They show details of the arrangement on an enlarged scale. In particular, FIG. 8 shows frame-connecting part 11 that receives shown fabric shaft 7 as well as diverter shaft 8 (not shown) in catch tabs provided to this end by clipping them in. FIG. 8 shows frame-connecting part 11 with and without clipped-in fabric shaft 7 and cord reel 9. FIG. 9 shows the further frame-connecting part 14 also in two views with reels 17 of which reel 17 is half pulled out in one view. Reels 17 function as described for cord diverting. Frame-connecting parts 14 to be placed in the lower left and the lower right corners of the frame are mirror-symmetrical and have two bores 23 into which reels 17 can be inserted. The roller blind device can be driven left or right by inserting reels 17 into the one or the other bore.
FIG. 11 shows holder 20 for motor 18 in detail. This holder 20 consists of a �shoe� connected to lower frame part 14, into which motor 18 can be inserted precisely. Clamp bracket 27 is placed over the motor body and tightened and locked by screws 28. As a result, motor 18 can be shifted on its longitudinal side as needed by loosening screws 28 and the bevel gears can be brought into exact engagement with each other.
