6. The device according to claim 1, wherein the flexible fabric enters the device along an outwardly bent arcuate upper portion of a side wall of the receiving profile, follows the side wall of the receiving profile downward toward the keder rail, enters the keder rail trough the longitudinal opening, loops around the keder core, exits the keder rail trough the longitudinal opening, and upwardly follows the side wall of the receiving profile, wherein the keder rail is arranged in the receiving profile such that the keder channel is facing away from the flexible fabric entering to the device.

7. The device according to claim 1, wherein a fabric region leading in direction of the keder rail and a fabric region end piece protruding from the keder rail are guided on an underside of the keder rail so that they mutually jam each other.

8. The device according to claim 1, wherein the receiving profile comprises a substantially U-shaped receptacle, in an upper region of which the flexible fabric is introduced and guided on a front side of the receiving profile to the keder rail which is arranged in a lower region of the receiving profile.

9. The device according to claim 8, wherein the receiving profile comprises a cover which is releasably arranged on the receptacle.

10. The device according to one of claim 8, wherein the receiving profile comprises attachment grooves with which the receiving profile can be slidably attached on lugs or angle brackets with hammer head screws.

11. The device according to claim 1, wherein the longitudinal opening faces a flat bottom of the receiving profile.

12. A device for attaching a flexible fabric, comprising: a receiving profile; a keder rail having a keder channel accessible through a longitudinal opening, the keder rail being arranged at a slidingly adjustable height in the receiving profile; a keder core arranged within the keder channel; a plurality of adjustment members arranged at a distance from one another and engaging a top of the keder rail through corresponding tongue and groove profiles, each adjustment member being slidingly arranged on a bolt and pushed towards a bottom of the receiving profile by a compression spring which is coaxially held on the bolt above the adjustment member; and a releasable cover closing off an upper portion of the receiving profile.

DETAILED DESCRIPTION

(4) Referring to FIG. 1, a device 1 for attaching a flexible fabric to a structure such as a building comprises a keder rail 10 having a keder channel 100. Inserted into the keder channel 100 is a keder core 11 attached to the fabric 2. A receiving profile 12 is also provided on the device 1. In the receiving profile the keder rail 10 is arranged relocatable in height, i.e. at an adjustable height.

(5) The receiving profile 12 advantageously comprises a substantially U-shaped receptacle 120, in the upper region of which the fabric 2 is introduced. The fabric 2 is guided on a front side of the receiving profile 12 to the keder rail 10. The keder rail 10 is arranged in a lower region of the receiving profile 12. Furthermore, the receiving profile 12 preferably comprises a cover 121 reversibly arranged on the receptacle 120.

(6) Particularly advantageously, the at least one keder rail 10 or an adjustment member 13 holding the at least one keder rail 10 is arranged on at least one threaded rod 14 or at least one threaded screw 14. The at least one threaded rod 14 or at least one threaded screw 14 is rotatably accommodated on the receiving profile 12. The keder rail 10 or the adjustment member 13 holding the keder rail 10 can be displaced in height by the at least one threaded rod 14 or at least one threaded screw 14.

(7) It is advantageous in this case that the at least one threaded rod 14 or at least one threaded screw 14 comprises a head 140 which is accessible outside of the receiving profile 12. After engaging the head with a suitable tool the threaded rod 14 or the threaded screw 14 can be adjusted/rotated for adjusting the height of the keder rail 10.

(8) As shown in FIG. 1, the keder rail 10 and the adjustment member 13 comprise corresponding engagements 101, 130, which provide a reversible, accurately fitting connection between the keder rail 10 and the adjustment member 13. Thus, the keder rail 10 can be easily and effortlessly introduced from below into the adjustment member 13.

(9) The keder rail 10 is preferably arranged in the receiving profile 12 such that the keder channel 100 is aligned substantially in the direction opposite of the fabric 2 attached to the device 1. The keder channel 100 thus faces away from the fabric 2. Further, a fabric region 20 leading in the direction of the keder rail 10 and a fabric region end piece 21 protruding from the keder rail 10 are guided on an underside 102 of the keder rail 10 in such a way that these regions 20, 21 mutually jam. The advantage of this embodiment is to be seen in the fact that more or less of the fabric 2 can be wrapped and thus the dimensions of the entire fabric 2 can be easily influenced.

(10) The fabric 2 in the keder channel 100 is held particularly advantageous by adjusting jaws 15 which press the keder rail 10 with the fabric 2 downward when adjusting the threaded rod 14 or the threaded screw 14 and thus provide an individually adjustable tension of the fabric 2.

(11) Through rotation on the head 140, the adjusting jaws 15 then press the keder rail 10 with the fabric 2 downward and thus provide an individually adjustable tension of the fabric 2.

(12) To mitigate peak wind loads, it may be advantageous that the keder rail 10 or adjustment member 13 holding the keder rail 10 is arranged spring-loaded on the threaded rod 14 or the threaded screw 14. A compression spring 16 may preferably be installed for this purpose. In addition, this spring provides automatic tension compensation in the event of temperature changes. This particularly material-preserving attaching method makes it possible to easily outlast the warranty periods required in the construction and significantly reduce assembly costs, for example, in textile facades.

(13) The receiving profile 12 further comprises attachment grooves 1200, with which the receiving profile 12 is slidably attached on lugs or angle brackets by means of commercially available hammer head screws.

(14) While the present invention has been described with reference to exemplary embodiments, it will be readily apparent to those skilled in the art that the invention is not limited to the disclosed or illustrated embodiments but, on the contrary, is intended to cover numerous other modifications, substitutions, variations and broad equivalent arrangements that are included within the spirit and scope of the following claims.
