[0026] FIG. 2a a schematic drawing of front view of a door system according to the invention;

[0027] FIG. 2b a three-dimensional drawing of a front view of a door system according to the invention;

[0028] FIG. 3a a three-dimensional drawing of the pulley system;

[0029] FIG. 3b a further three-dimensional drawing of the pulley system;

[0030] FIG. 3c a schematic drawing of a front view of the pulley system;

[0031] FIG. 4 a detail of a first roller of the pulley system;

[0032] FIG. 5 a detail of a second roller of the pulley system;

[0033] FIG. 6 a detail of a pulley system;

[0034] FIG. 7a a schematic drawing of a second embodiment of the pulley system;

[0035] FIG. 7b a further drawing of the second embodiment of the pulley system;

[0036] FIG. 7c a detail of the pulley system according to the second embodiment.

[0037] FIG. 1 is a schematic drawing of a side view of a door system 1 according to the invention. Therein, reference numeral 8 denotes a drive device that is used for opening and closing the door. In the embodiment according to the invention, a pulley system 10 is provided as a drive device, and comprises in particular a first roller 14, a second roller 16, a cable 12, a drive motor 20 and a drive spindle (not visible in this drawing). A narrow side S of the slat elements 6 is also visible in this drawing, the slat elements 6 having a chamfer or slope 25 on the upper and lower narrow side S.

[0038] Moreover, reference numeral E denotes a plane of the ground surface O, and reference numeral 9 denotes the box, which is arranged below this ground surface O and serves to receive the slat elements 6 during an open state of the door.

[0039] Moreover, FIGS. 2a and 2b are a front view of the door system 1 according to the invention. Reference numeral B denotes the broad side of the slat elements 6. In this drawing, in particular the orthogonal relationship between the door 2 or the slat elements 6 and the guide elements 4 and 5 is visible, the guide elements 4 and 5 extending in a horizontal direction H and the slat elements 6 in a vertical direction V.

[0040] FIG. 3a-3c show the aforementioned pulley system 10. In this case, there are preferably two pulley systems 10 of this type, one system, or the cable 12 and the rollers 14 and 16 (not visible from the outside), being arranged in each of the guide elements 4 and 5. It can be seen that the two second rollers 16 are connected to one another via a drive spindle 11, and the drive spindle 11 is driven by way of a drive motor 20. Arranging two pulley systems of this type is advantageous in particular because this can make uniform opening and closing of the door possible, and there is no risk of for example the side of the door on which no pulley system is arranged tilting inside the guide element.

[0041] FIGS. 4 and 5 are each a detail of the aforementioned first roller 14 and second roller 16. In this case, preferably, the first roller 14 is a roller around which the cable 12 is merely guided when the door is opened and closed, and the second roller 16 is a roller around which the cable 12 is wound and unwound when the door is opened and closed.

[0042] FIG. 6 is a further detail of the pulley system 10, in particular the arrangement or connection of the cable 12 and the rollers 14, 16 being visible here.

[0043] FIG. 7a-7c show a further embodiment of the pulley system, this being in particular a pulley block system. By contrast with the embodiment shown in FIG. 1-6, in this case the pulley system 10 additionally has a third roller 18, in such a way that the cable 12 is guided over three rollers 14, 16, 18 in total. This third roller 18 is preferably arranged below the first roller 14 in a vertical direction and offset from the first roller 14 and/or the second roller 16 in a horizontal direction, as can be seen in particular from FIGS. 7a and 7b.

[0044] Here, reference numeral 19 denotes a sensor device, which, as was explained in greater detail above, is in particular for monitoring a tension of the cable, in such a way that for an untensioned cable for example the opening and/or closing movement of the door can be interrupted or stopped. Preferably, a sensor device of this type may also be provided in the embodiments of FIG. 1-6.

[0045] The Applicant reserves the right to claim all features disclosed in the application documents as essential to the invention so long as they are novel, individually or in combination, in respect of the prior art. It is further noted that the individual drawings have also described features that may be advantageous in their own right. A person skilled in the art will immediately recognize that a particular feature described in a drawing may be advantageous even without the incorporation of further features from said drawing. A person skilled in the art will further recognize that advantages may also result from a combination of a plurality of features shown in individual or in different drawings.
