DETAILED DESCRIPTION

[0079] FIG. 1 is a partial diagrammatic representation, in a cross section view, of a non-limitative embodiment of a frame according to the invention.

[0080] The frame 100, shown in FIG. 1, comprises a fastening device 102 used for fastening a fabric T onto a profile 104, forming a side of a frame for example.

[0081] The profile 104 comprises an inner edge 104.sub.1 located on the side of the fabric T, and an outer edge 104.sub.2 located on the opposite side to the fabric T. In other words, the fabric T extends to the side of the inner edge 104.sub.1 of the profile 104.

[0082] The profile 104 comprises a groove 104.sub.3 for fastening the fastening device 102 to the profile 104, for example by clamping, over-centre locking, clipping, etc.

[0083] The fastening device 102 comprises a fastening part 106 that is accommodated in the groove 104.sub.3. The groove 104.sub.3, or the fastening part 106, can be notched in order to assist with holding the fastening part 106 in the groove 104.sub.3.

[0084] The fastening device 102 also comprises a covering part 108, forming an overhang, and extending from the groove 104.sub.3 to the outer edge 104.sub.2 of the profile and covering a part, or the entirety of the profile, between the groove 104.sub.3 and the outer edge 104.sub.2 of the profile. The width of the covering part 108 is adjusted so that the distal end 110 of the covering part 108 is aligned with the outer edge 104.sub.2 of the profile 104.

[0085] In other words, the covering part 108, or the overhang 108, extends beyond the fastening part 106 in the direction 112 from the inner edge 104.sub.1 of the profile 104 to the outer edge 104.sub.2 of the profile 104.

[0086] The covering part 108 is itself covered by the fabric T, up to the distal end 110 of the covering part 108.

[0087] The fabric T is fastened to the upper surface 114 of said covering part 108, for example by bonding or welding.

[0088] Thus, viewed from a direction 116 facing the fabric T, the profile 104 is entirely covered by the fabric T and the profile 104 is not visible.

[0089] The profile 104 is produced from aluminium and the fastening device 102 is in the form of a flexible joint produced from silicone.

[0090] FIG. 2 is a partial diagrammatic representation, in a cross section view, of a second non-limitative embodiment of a frame according to the invention.

[0091] The frame 200, shown in FIG. 2, adopts the same elements as the frame 100 in FIG. 1.

[0092] Unlike the frame 100 in FIG. 1, the frame 200 utilizes a fastening device 202, the covering part 108 of which stops before the outer edge 104.sub.2 of the profile 104. In other words, the distal end 110 of the covering part 108 is set back with respect to the outer edge 104.sub.2 of the profile 104.

[0093] The fabric T entirely covers the covering part 108, including the distal end 110 of the covering part 108.

[0094] In this configuration, the fabric T can be fastened to the distal end 110 of the covering part, and/or to the upper surface 114 of the covering part 108.

[0095] FIG. 3 is a partial diagrammatic representation, in a cross section view, of a third non-limitative embodiment of a frame according to the invention.

[0096] The frame 300, shown in FIG. 3, adopts the same elements as the frame 200 in FIG. 2.

[0097] Unlike the frame 200 in FIG. 2, the frame 300 utilizes a fastening device 302, the fastening part 106 of which has a smaller thickness compared with the thickness of the fastening part 106 of the fastening device 202. The fabric T entirely covers the covering part 108, including the distal end 110 of the covering part 108, and extends up to the fastening part 106. The peripheral border of the fabric T is inserted into the groove 104.sub.3 with the fastening part 106, so that it is jammed in the groove 104.sub.3 between the fastening part 106 and the profile 104.

[0098] In this configuration, the fabric T can be fastened to the fastening part 106, and in particular to the surface of the fastening part 106 located on the side of the outer edge 104.sub.2 of the profile 104. In particular, the fabric T can be bonded, welded or sewn onto this surface of the fastening part 106.

[0099] FIG. 4 is a diagrammatic representation, in a cross section view, of a non-limitative embodiment of another fastening device according to the invention.

[0100] The fastening device 402 in FIG. 4 is a preferred embodiment.

[0101] The device 402 in FIG. 4 comprises, like devices 102, 202 and 302, a fastening part 106 and a covering part 108.

[0102] Moreover, in the fastening device 402 in FIG. 4, the thickness of the covering part 108 reduces on the side of its distal end 110.

[0103] In particular, the distal end 110 of the covering part 108 is chamfered. This chamfered distal end 110 is obtained by: [0104] a first oblique cut 404 starting from the upper surface 114 and returning towards the profile, and [0105] a second oblique cut 406 starting from the lower surface and receding from the profile.

[0106] The first cut 404 is made over a greater distance compared with the second cut 406 so that the point of the chamfer is located closer to the profile.

[0107] FIG. 5 is a partial diagrammatic representation, in a cross section view, of another embodiment of a frame according to the invention.

[0108] The frame 500, shown in FIG. 5, utilizes the fastening device 402 in FIG. 4, in the configuration shown in FIG. 3.

[0109] As a reminder, in this configuration the fabric T entirely covers the covering part 108, including the distal end 110 of the covering part 108, and extends up to the fastening part 106 located in the groove 104.sub.3. The fabric T is fastened to the surface of the fastening part 106 located on the side of the outer edge 104.sub.2 of the profile 104. The border of the fabric T is thus located in the groove 104.sub.3.

[0110] The width of the covering part 108 is adjusted so that the covering part 108 extends beyond the outer edge 104.sub.2 of the profile 104. In other words, the distal end 110 of the covering part 108 projects from the profile 104 in the opposite direction to that in which the fabric T extends.

[0111] FIG. 6 is a partial diagrammatic representation, in a cross section view, of a non-limitative embodiment of an installation according to the invention.

[0112] The installation 600, shown in FIG. 5, is obtained by assembly end-to-end of two frames 500.sub.1 and 500.sub.2, identical to the frame 500 in FIG. 5. The assembly of the frames 500.sub.1 and 500.sub.2 can be carried out by screwing or bolting or by any other known fastening method.

[0113] The frame 500.sub.1 is formed by a fabric T.sub.1, a frame 104.sub.1 identical to the frame 104 in FIGS. 1-5 and a fastening device 402.sub.1 identical to the fastening device 402 in FIG. 4.

[0114] The frame 500.sub.2 is formed by a fabric T.sub.2, a frame 104.sub.2 identical to the frame 104 in FIGS. 1-5 and a fastening device 402.sub.2 identical to the fastening device 402 in FIG. 4.

[0115] As can be seen in FIG. 6, the distal end of each fastening device, respectively 402.sub.1 and 402.sub.2, extending from the outer edge of the frame, respectively 104.sub.1 and 104.sub.2, the fastening devices 402.sub.1 and 402.sub.2 come into contact with one another at their respective distal ends, being held tightly by compression against one another. This makes it possible to ensure a connection and perfect continuity between the frames 500.sub.1 et 500.sub.2, in particular at the junction of these frames.

[0116] Thus, viewed from the direction 116 facing the fabrics T.sub.1 and T.sub.2, and thus facing the structure 600, the frames 104.sub.1 and 104.sub.2 are not visible.

[0117] FIG. 7 is a diagrammatic representation, in a cross section view, of a non-limitative embodiment of a profile according to the invention, in a configuration for use.

[0118] The frame 700, shown in FIG. 7, adopts the same elements as the frame 300 in FIG. 3.

[0119] Unlike the frame 300 in FIG. 3, the frame 700 utilizes a profile 702 that is different from the profile 104.

[0120] Unlike the profile 104 shown in FIG. 3, the profile 702 in FIG. 7 comprises a greater thickness E1 between its inner edge 104.sub.1 and the groove 104.sub.3, compared with its thickness E2 between the groove 104.sub.3 and its outer edge 104.sub.2.

[0121] In particular, the thickness E1 is chosen so that the profile 702 and the fastening device 302 are at the same level at the fastening part 106.

[0122] This difference in thickness can for example be obtained by reducing the thickness of a profile existing between the groove 104.sub.3 and the outer edge 104.sub.2 by a desired quantity. This reduction in thickness can be produced by removing material between the groove 104.sub.3 and the outer edge, for example by a machining process.

[0123] Alternatively, this difference in thickness can be provided during the manufacture of the profile.

[0124] FIG. 8 is a partial diagrammatic representation, in a cross section view, of another non-limitative embodiment of a frame according to the invention.

[0125] The frame 800, shown in FIG. 8, adopts the same elements as the frame 200 in FIG. 2.

[0126] Unlike the frame 200 in FIG. 2, the frame 800 utilizes a fastening device 802, the covering part 106 of which has a smaller thickness compared with the thickness of the covering part 106 of the fastening device 202.

[0127] The fabric T entirely covers the covering part 108, including the distal end 110 of the covering part 108, and all the way under the covering part and stops at the fastening part 106, or just before the fastening part 106. The peripheral border of the fabric T is inserted under the covering part 108, so that it is jammed between the fastening part 108 and the profile 104.

[0128] In this configuration, the fabric T can be fastened to the covering part 108.

[0129] In the examples described, the groove 104.sub.3 is oriented perpendicularly with respect to the fabric. Of course, according to alternative embodiments, the groove can be oriented: [0130] towards the outer edge 104.sub.2. In particular, the groove can be oriented in a direction forming an angle greater than 90, or even greater than 100, with respect to the fabric, or [0131] towards the inner edge 104.sub.1. In particular, the groove can be oriented in a direction forming an angle less than 90, or even less than 80, with respect to the fabric.

[0132] Moreover, in the examples described, the covering part forms a right angle with respect to the fastening part. According to alternative embodiments, the covering 108 and fastening 106 parts can form an angle: [0133] less than 90, and in particular less than 80, in particular when the groove 104.sub.3 is oriented towards the inner edge 104.sub.1, or [0134] greater than 90, and in particular greater than 100, in particular when the groove 104.sub.3 is oriented towards the outer edge 104.sub.1.

[0135] Of course, the invention is not limited to the examples which have just been described.

[0136] For example, it is possible to use a fastening means different from a groove on the profile side. It is also possible to use other shapes of profiles than those shown.
