Fastening devices for wall curtains are known, in which the fastening members are extruded x-strips, the longitudinal edges of which are curved on the same side.

One of the moldings is pre-attached along the two edges of the curtain wall, the other is attached to the two edges of the curtain and the curtain is fitted by grasping the loose moldings from a fixed moldings, turning the loose moldings around one or more times, depending on the curtain. This technology has proven to be extremely efficient, convenient, fast and inexpensive.

The fixed and loose fastening moldings can be quite different in shape and dimensions, so that said technique can be properly applied according to the cladding problems to be performed, whether one, two or even three curtain layers are used.

2 56312 In practice, it has been found that in the case of certain types of impregnated or non-impregnated curtains, it would be desirable to provide an additional adhesive effect between the curtain and the members of the curtain associated with the solid and / or loose moldings. In certain applications, it has also been found to be best that the curtain and the associated parts of the loose-form list are not glued together, which may be quite sufficient in the case of numerous other types of curtains.

More particularly, the invention relates to a device for fastening at least one wall curtain, the device consisting of at least two parts, first and second, in the form of a strip, the longitudinal, parallel edges of which are bent to form a hinge chute and a fastening chute, the first part having a front surface between the edges bent on the same side of the part, and a back surface with means for fixing this part to the wall, and said second part has a front surface and a back surface with at least one area with protrusions.

In order to satisfy said need for additional adhesion, all or some of the parts of the moldings which come into contact with the curtain according to the present invention are provided with curtain-permeable projections which penetrate the curtain during wall cladding work, systematically providing a very strong adhesion and fastening between the curtain and moldings. The features of the invention appear from the following claim.

It has been found that the co-operation of the different areas with the projections in this way results in a very strong fastening of the curtain without compromising the integrity of the curtain and the portability of the system, which makes it possible to remove and restore the curtain at will.

It is clear that the protrusions can vary greatly in shape, size, density and distribution depending on the quality of the curtain to be attached.

An embodiment of the invention will now be described in more detail by way of example with reference to the accompanying drawings, in which Figure 1 shows a section of two fastening moldings used together, Figures 2 and 3 show the members of Figure 1 in two operating positions, intermediate and final, Figure 4 shows a modification of Figure 3, Figs. 5-8 schematically show perspective views of parts of the fastening moldings, and Fig. 9 shows on a larger scale point F10 in Fig. 8.

As shown by way of example in Figures 1 to 4, the solid shape strips 1, i. the two longitudinal edges 2, 3 of the fastening moldings intended to be pre-fastened to the wall to be clad are curved so as to form a suspension edge. The rear surface of the mold strip is provided with anchoring members 4 with which the strip is fixed to the wall. The front surface of said fastening member 1 has a region with protrusions 5. The loose moldings 6 are likewise made in the shape of a mold, both longitudinal edges 7, 8 of which are curved so that they can be hung to be fixed to the moldings 1. In these loose moldings 6 has protrusions 9 and 10 on both their backs and fronts.

Said protrusions are distributed so that the two areas in which the protrusions 9 are located are located in the area of the fixed strip 1 in which there are no protrusions 5 when the strips are connected to each other.

This arrangement makes it possible, as schematically shown in Figures 2 and 3, that when the loose mold strip 6 is suspended from the fixed mold strip 1, the first curtain 11 is gripped by the protrusions 9 of the temporarily lower part of the mold strip 6 and the second curtain 12 is gripped by the loose mold strip 6. temporarily bringing the loose mold strip 6 by turning it and moving it into contact with the fixed mold strip 1, as shown in Fig. 3, a very strong fastening of both curtains 11, 12 between the different protrusions and the areas opposite them, i.e. the interconnected mold strips, is obtained. Between 1 and 6. The fixed shape strip 1 is a continuous, planar strip.

4 S6312 Fig. 4 shows a somewhat different structure, in which the fixed mold strip 1 is instead of a simple planar strip, a mold strip with a central portion 13 corresponding to the protruding area 5 displaced to reduce the contact surface with the wall to which the fixed mold strip 1 is attached. The protrusions of the strips can be made quite varied in shape and dimensions. According to the schematic representation of Figure 5, these protrusions may be continuous ridges 14 with a triangular cross-section. This structure makes it possible to manufacture fastening moldings by extrusion, which is a fast and inexpensive industrial method. Alternatively, as shown in Figure 6, the protrusions 15 may be made by casting, e.g. in the form of small cones or pyramids. An analogous result can be obtained, as shown in Fig. 7, by compression molding, in which case the protrusions are likewise conical or triangular, but hollow. As shown in Figures 8 and 9, the protrusions can also be formed by stamping. These protrusions 17, as shown in Fig. 9, are formed by burrs formed during stamping. The stamping is preferably performed with triangular cross-sections, thus providing an orientation of the burrs in three converging directions, which may be particularly advantageous in order to achieve good adhesion.
