DETAILED DESCRIPTION

[0033] In relation to FIGS. 1 to 3, a device 1 for attaching a cloth for producing a tensioned-cloth false ceiling is described, comprising a first profiled member 2 and a second profiled member 4 able to be embedded in the first profiled member 2. The first profiled member 2 and the second profiled member 4 are hereinafter referred respectively as the profiled rail or main profiled member 2 and additional profiled member 4.

[0034] In the embodiment illustrated, the main profiled member 2, preferably made from aluminium, consists of a profiled rail in the form of a right-angled triangle, intended to be fixed to a support for the purpose of attaching a cloth by its peripheral edges provided, to do this, with an attachment means in the form of a harpoon. Such a profiled member is known and the general form of such a profiled member is described in the applications FR 2952087 and FR 2970013 in the name of the applicant. Any other form of main profiled member may of course be provided without departing from the scope of the invention. Such a profiled member is intended in particular for attaching a PVC cloth.

[0035] Like any profiled rail used for installing a cloth comprising attachment means, the profiled member 2 comprises a reception groove 20 intended to receive the attachment means. In the embodiment illustrated, the reception groove 20 has a U-shaped cross section and is delimited by two lateral walls 21, 23 and a bottom wall 22. The ends of the U-shaped lateral walls, opposite to the bottom wall 22, define an opening 7 for passage of the means for attaching the cloth in the reception groove 20. In order to attach the means for attaching the cloth, the internal face of one of the lateral walls comprises a longitudinal attachment shoulder 24. In the example illustrated, the attachment shoulder 24 is provided on the internal face 230 of the external lateral wall 23. External wall means the wall furthest away from the space delimited by the ceiling and the cloth when the latter is in place (awning). Moreover, internal face designates a face disposed on the groove side. Conversely, external face designates a face disposed on the side opposite to the groove.

[0036] As will be seen later, the shoulder 24 is sized so as to receive a slot 44 provided on the additional profiled member 4. The fitting of the shoulder 24 in the slot ensures the holding of the additional profiled member 4 in the reception groove 20 of the main profiled member 2. Advantageously, the shoulder 24 has a flat attachment surface 240. The advantage of this configuration is improving the holding of the additional profiled member 4 in the reception groove 20 and thus preventing any unwanted withdrawal of the additional profiled member 4 from the main profiled member 2.

[0037] The additional profiled member 4, advantageously produced from PVC, has a form substantially complementary to that of the reception groove 20 of the main profiled member 2.

[0038] More particularly, the additional profiled member 4 is, in the embodiment illustrated, in the form an elongate blade, preferably with the same length as that of the main profiled member 2, with a substantially U-shaped cross section. The arms 41, 43 of the blade are sized so as to extend over the entire width of the lateral walls 21, 23 of the groove 20 of the main profiled member 2. Width of the arms means the distance separating the bottom wall 42 of the U shape and the free end of the arms. Likewise, width of the lateral walls of the reception groove means the distance separating the bottom wall 22 of the groove and the end of the lateral walls opposite to the bottom wall 22.

[0039] The arm 41 of the additional profiled member 4 is provided, on its internal face 410, with semi-rigid or flexible longitudinal projections 40. Support arm 41 will be spoken of hereinafter. The projections 40 are arranged on the arm 41 and sized so as to come into abutment against the internal face 430 of the arm 43 of the additional profiled member 4 when the latter is in place in the reception groove 20.

[0040] The arm 43 opposite to the one carrying the projections 40 (arm 41) comprises a slot 44 sized so as to receive the shoulder 24 of the lateral wall 23 of the reception groove 20. In the embodiment illustrated, the slot 44 has been formed by pressing of the arm 43. It is provided on the arm 43 so that the width of the downstream portion of the slot 44 (portion of the arm 43A) is substantially equal to the distance separating the bottom wall 22 of the reception groove 20 the shoulder 24.

[0041] The placing of the additional profiled member 4 takes place by elastic fitting of the additional profiled member 4 in the groove 20 of the main profiled member 2. To do this, the additional profiled member 4 is positioned until the slot 44 comes to snap onto shoulder 24 of the groove 20 of the main profiled member 2. Any movement between the additional profiled member 4 and the main profiled member 2 is then prevented, the additional profiled member 4 being held in the main profiled member 2 by the shoulder 24. The arm 43 thus forms a retaining arm.

[0042] In order to facilitate the insertion and guidance of the peripheral edge of the cloth, the portion of the arm 43 upstream of the slot 44 (arm portion 43C) has an internal face arranged so as to form a ramp 46 from the end of the arm 43 as far as the fitted-in portion 43B of the arm 43A.

[0043] The terms upstream and downstream are defined with respect to the movement of insertion of the cloth in the additional profiled member 4. Thus the zone situated between the pressed-in portion zone 43B of the arm and the opening 45 allowing entry of the cloth is defined as being an upstream zone of the pressed-in portion, while the zone situated between the pressed-in portion 43B and the bottom wall 42 is defined as being a downstream zone of the pressed-in portion 43B.

[0044] In the previously described embodiment, the reception groove 20 has a U-shaped cross section. The invention is not limited to this type of groove and that the invention may be implemented with a main profiled member 2 having a groove in the form of a V or the form of a trough provided with any bottom wall, the additional profiled member 4 having in any event a cross section with a complementary form.

[0045] Moreover, in the embodiment illustrated, the additional profiled member 4 comprises four projections, with different lengths, distributed over the arm 41 between the end of the arm and a zone situated facing the pressed-in portion of the arm 43. The deformable projections also have a flange profile. The projections are not limited to this form and any other form may be provided without departing from the scope of the invention. Likewise, the number of projections can vary according to the dimensions of the additional profiled member and the degree of clamping required.

[0046] From the above description, it will be understood that the additional profiled member 4 enables a cloth with no attachment means to be attached to a main profiled member initially intended for attaching cloth provided with attachment means. Thus the attachment device enables cloth of any type to be used.

[0047] The attachment device also makes it possible to combine mixed frames. This is because, when the main profiled member comprises a plurality of reception grooves suitable for holding an attachment means of a cloth, this method can allow the attachment of a plurality of cloth, some being equipped with attachment means, the other having none. In the latter case, an additional profiled member will be integrated in the corresponding reception groove. FIG. 1 illustrates the use of such a frame, the cloth 5 with no attachment means being fixed in the reception groove 20 by clamping of projections against the internal face 430 of the retaining arm 43 while the cloth 6 provided with attachment means 60 is fixed conventionally in the groove 25.

[0048] In the previously described embodiment, the attachment device 1 comprises only one additional profiled member. Provision can be made to integrate a plurality of additional profiled members in the main profiled member, the form and dimensions of the additional profiled members being adapted to the form and dimensions of the reception groove for which they are intended.

[0049] The invention is described above by way of example. It will be understood that a person skilled in the art is in a position to produce different variant embodiments of the invention without departing from the scope of the invention.
