Description

[0001] The invention relates to a device for attaching a textile web according to the preamble of claim 1.

[0002] For presentation purposes at trade fairs, it is known to suspend printed textiles in a profile or to stretch them on partition walls formed from profile elements connected to each other via special connectors. For this purpose, the profile is designed as a keder profile, and a cylindrical keder is attached to the textile, which is inserted into the slotted bore arranged in the keder profile. Keder profiles designed as C-profiles are also known. For such a keder profile, keders with a rectangular cross-section are used, which are inserted into the keder profile. On their reverse side, opposite the keder receptacle, the profiles regularly have a C-profile section for receiving fasteners, in particular T-nuts for connection to a frame profile or for receiving support elements.

[0003] A disadvantage of the known presentation devices is that attaching a textile panel by inserting the keder attached to it is very time-consuming. Furthermore, the keder is subject to increasing wear and tear with repeated use due to abrasion from being inserted and removed from the keder profile.

[0004] The invention aims to remedy this problem. The invention is based on the objective of providing a device for suspending a textile web that enables simple and low-wear fastening of a textile web equipped with a keder. According to the invention, this objective is achieved by a device with the features of the characterizing part of claim 1.

[0005] The invention provides a device for suspending a textile web, enabling simple and low-wear fastening of a textile web with a

[0006] The design allows for the use of a textile web equipped with a keder (welt). The first recess is formed by a longitudinally extending U-profile section, enabling easy insertion of the keder. A second recess, spaced apart from the first in the direction of the C-profile section, contains a pivoting hinge profile that rests against the first recess in its end-position pivot position, thus facilitating easy fixation of the keder within the first recess.

[0007] In a further development of the invention, the second receptacle is designed as a channel with a substantially circular arc-shaped cross-section, wherein the folding profile has a longitudinally extending, substantially cylindrical projection which is incorporated into the second receptacle and by means of which the folding profile is pivotably mounted in the second receptacle. This achieves a hinge-like pivot connection between the folding profile and the retaining profile.

[0008] In an embodiment of the invention, the molded part is provided with a longitudinally extending cutout, preferably formed by two plane surfaces angled towards each other. The second receptacle has a stop edge against which the cutout rests in the end-position pivot position of the folding profile. This allows for easy assembly of the folding profile in the second receptacle. After the molded part is inserted into the second receptacle, it is secured in the second receptacle after pivoting the folding profile. The opening of the second receptacle is dimensioned such that it corresponds approximately to the reduced diameter of the molded part, which can be inserted through the opening into the second receptacle.

[0009] In a further embodiment of the invention, the folding profile has a stop rib, preferably extending over its entire width and spaced apart from its transverse side opposite the molded area, with which the folding profile rests against the first receptacle in its end-position pivot position. This allows a textile web to be clamped between the retaining profile and the stop rib.

[0010] In a further development of the invention, at least one bore is arranged in the end section of the hinged profile bounded by the stop bar. When the stop bar rests against the first receptacle, this bore aligns with a threaded bore provided in the first receptacle. This allows the insertion of at least one fastening screw, which can be screwed through the bore and into the threaded bore, thereby reliably connecting the textile web to the retaining profile. Tightening the screw also increases the contact pressure of the stop bar against the retaining profile, allowing the textile web to be clamped between the hinged profile and the retaining plate.

[0011] In an embodiment of the invention, the folding profile has a first locking tab on its side facing the retaining profile, which is locked in the end-position pivot position of the folding profile with a second locking tab arranged on the retaining profile for this purpose. This prevents the folding profile from pivoting open automatically.

[0012] In a further embodiment of the invention, the first locking lug extends over the entire length of the folding profile and / or the second locking lug extends over the entire length of the retaining profile. This improves the holding force of the locking connection between the folding profile and the retaining profile.

[0013] In a further development of the invention, the holding device and / or the folding profile is made of aluminum, preferably as an aluminum casting, and in particular as an aluminum extrusion. This results in a weight-reduced device.

[0014] In one embodiment of the invention, the retaining profile has a flat back wall, via which the first receptacle is connected to the C-profile section, the second receptacle being arranged on the C-profile section and connected to the back wall via a connecting web above the first receptacle, the connecting web forming an acute angle with the back wall. This results in a material-reduced design, thereby enabling a further reduction in the device's weight.

[0015] The invention further relates to a presentation device with such a device according to claim 10.

[0016] In a further development of the invention, a screw is guided through at least one bore of the hinged profile, which penetrates the textile web and is screwed into a threaded bore of the first receptacle. This ensures reliable securing of the textile web under maximized clamping pressure between the retaining profile and the hinged profile.

[0017] Other embodiments and configurations of the invention are specified in the remaining dependent claims. Exemplary embodiments of the invention are illustrated in the drawings and are described in detail below.
