Abstract
The fabric mounting system (1) includes a mounting profile (4) adapted to be mounted to a wall or ceiling and at least one fabric retaining element (5) engaging the mounting profile and being adapted to retain an edge (6) of the fabric (2). First and second supporting faces (9, 10) of the mounting profile (4) are mutually tapered in such a tapering direction (T) that a resilient bias of first and second legs (7, 8) of the fabric retaining element (5) urges the first and second legs (7, 8) to slide along the first and the second supporting faces (9, 10), respectively, to thereby displace the fabric retaining element in a direction generally against the tapering direction (T) and in a fabric tensioning direction (F) being transverse to a longitudinal direction (L) of the mounting profile (4) in order to stretch the fabric (2) in its retained position.

[0043] The fabric mounting system 1 includes at least a first mounting profile 4 having a longitudinal direction Las illustrated in
[0044] The first and the second supporting faces 9, 10 of the first mounting profile 4 are mutually tapered in such a tapering direction T that the resilient bias of the first and second legs 7, 8 of the first fabric retaining element 5 urges the first and second legs 7, 8 to slide along the first and the second supporting faces 9, 10, respectively, to thereby displace the first fabric retaining element in a direction generally against the tapering direction and in a fabric tensioning direction F being transverse to the longitudinal direction L of the first mounting profile 4 in order to stretch the fabric 2 in its retained position as illustrated in
[0045] Preferably, and as illustrated in the embodiments of
[0046] On the other hand, in the embodiments according to the invention illustrated in
[0047] Preferably, the fabric mounting system 1 includes a not shown second mounting profile to be arranged and mounted to the wall or ceiling 3 at a distance from the first mounting profile 4 and preferably symmetrically in relation to the first mounting profile about a plane extending perpendicularly in relation to the fabric 2 which plane in
[0048] It is also possibly that the first and second mounting profiles may be arranged at either side of a corner of a building, whereby the fabric may extend around the corner where it may be supported preferably by means of a rounded edge, for instance provided on a profile mounted to the wall or ceiling at the corner.
[0049] The fabric mounting system 1 may include four corresponding mounting profiles each including at least one fabric retaining element and together forming a frame by means of which a rectangular piece of fabric may be retained. The mounting profiles may be connected at corners by means of not shown, suitable corner pieces forming a smooth transition for the fabric to be extended. In the same way, any suitable number of corresponding mounting profiles each including at least one fabric retaining element may together form a frame by means of which a corresponding piece of fabric may be retained. For example, the frame may have the form of a pentagon, a hexagon or any other suitable polygon. Furthermore, the mounting profile or profiles may also be curved whereby the corresponding fabric retaining element or elements may be correspondingly curved. For instance, one mounting profile may form a circle, an oval or other closed form in order to extend a correspondingly formed piece of fabric.
[0050] It may be an advantage according to the present invention that the fabric mounting system 1 as illustrated in the figures may be sold as one or a number of lengths of a first mounting profile 4 with corresponding one or more first fabric retaining element or elements. On the building site, the length of the first mounting profile 4 may be cut into suitable sizes of mounting profile corresponding to the actual dimensions of the building in or on which the fabric 2 is to be extended. In this way, an extended fabric may be arranged in a tailor-made fashion to fit a room of a building. In the case that the first fabric retaining element 5 is adapted to have the same length as the first mounting profile 4, the first fabric retaining element may correspondingly be cut into suitable sizes. Alternatively, the first fabric retaining element may be provided as a number of fabric retaining elements each having a shorter length than the length of the first mounting profile 4 and being adapted to be positioned one after the other in the longitudinal direction L of the mounting profile.
[0051] The first mounting profile 4 may be sold with the corresponding one or more first fabric retaining element 5 or elements already mounted in the fabric attachment position as illustrated in
[0052] As illustrated in
[0053] As an alternative to mounting the mounting profiles separately on a wall or ceiling at the building site, it is also possible to provide panels which are ready to mount on a ceiling or wall, whereby the panels are composed by mounting profiles arranged to form a frame and provided with fabric stretched over the panel by means of fabric retaining elements arranged in the mounting profiles according to the invention and as described herein.

For instance, the first and second legs 7, 8 may be connected to each other at both their ends, so that a closed form is created. As an example, the first and second legs 7, 8 could each form a half part of a tube, whereby the tube may have for instance a circular or an oval cross-section.
