  FIXING PROFILE FOR SURFACE COATING

  The present invention relates to a fixing profile for a flexible and stretched surface covering for false planks and / or wall decoration, intended to be fixed on at least one support wall, said fixing profile comprising at least one stine support plane at bear on said support wall and at least one longitudinal groove arranged to receive over all or part of its length at least one edge of said surface covering, said longitudinal groove being terminated by a clamp formed by a fixed jaw and d '' a movable jaw arranged to cooperate with each other and exert a retaining force on said surface covering engaged in said longitudinal groove, said fixed jaw being disposed outside and said movable jaw being disposed inside when said surface covering is stretched. In the context of the present application, the term surface coating includes flexible coverings for false ceilings and for wall decorations such as welded PVC strips, fabrics, sheets of nonwovens, heat-stretch coverings, coverings heat shrinkable, etc. These different types of surface coatings can be fixed to their support by simple and inexpensive methods of use, such as gluing or stapling. However, it is known that these means do not make it possible to obtain a uniform tension of the surface covering and that the aesthetics of the false ceiling or of the wall decoration are affected. Other more sophisticated fixing means using profiles have been developed and numerous patents have been filed in this field. We can cite the example of the publication WO

  A-9218722 which relates to a fixing device comprising two fitted parts.

  The major drawback of this device is that it does not make it possible to arrange a space between the surface covering and the ceiling or the wall to be covered, in order for example to include lighting, a heating system, etc. We can also mention the publication FR-A-2 630 476 which relates to a false plaSond consisting of a stretched sheet, hung along its edges to a support fixed to the walls. The support consists of a profile having a recess in which the harpoons attached to the edges of the sheet engage and lock. The installation of this surface covering requires the prior mounting of the harpoons along the edges of the sheet. This operation is tedious and does not allow, once the surface coating is installed, an easy readjustment of the tension applied to the

  surface coating in the presence of folds or warping.

  Faced with this particular problem, other systems using a fixing thread comprising a deformable and elastic longitudinal groove and in which comes

  insert the edge of the surface covering and a locking ring has been developed.

  The publication FR-A-2 601 575 describes such a device allowing the fixing of curtains without prior sewing. The edge of the curtain and the rod around which this edge is wound are inserted into the deformable and elastic longitudinal groove formed by the fixing profile. This fixing profile is not usable for the technical field of the present invention since it remains apparent which is unacceptable for the aesthetics of the assembly. The publication GB-A-1 395 602 also describes a fixing device by means of a rod fitting into the longitudinal groove of a fixing profile. This fixing profile also has a longitudinal recess intended to receive a clipped cover. This device therefore comprises three separate parts including the cover which remains visible. Publication WO-A-99 31330 describes a fixing device in which the fixing profile has two longitudinal grooves which can each receive and block a rod surrounded by the surface covering. The opening axes of these longitudinal grooves are oriented 90 one relative to

  the other so as to allow versatile use on a wall or ceiling.

  The engagement area of the longitudinal grooves has teeth intended to

  help maintain a cover to conceal the attachment area.

  The major drawback of the systems described in these four publications lies in the fact that they require the use and handling of at least one first complementary part forming the rod, and possibly a second complementary part forming the cover. Handling these additional parts

  makes installing the surface covering tedious and complicated.

  The publications FR-A-2 699 209, FR-A-2 699 210, FR-A-2 699 211, FR-A-2 699 212 attempt to remedy this problem by proposing fixing profiles comprising wings forming a fixing clamp provided with hooks or teeth, allowing the surface coating to be maintained without the use of additional parts. C: the publications describe different variant embodiments of dimensions and shapes making it possible respectively to produce a small clamp, to fold down the free face of the surface covering emerging from the clamp and to keep it wedged between the fixing profile and the perpendicular surface on the surface to be coated, to make it possible to fix the strip on a surface distinct from that to be coated, to have longitudinal grooves forming longitudinal grooves allowing passage of fixing nails or staples whose heads are supported on the outer faces delimited by these longitudinal grooves. The devices described in these documents cited above certainly allow a simple and inexpensive fixing of the surface coating, but do not allow the disassembly of the surface coating, the latter being damaged when it is removed from the clamp. Indeed, the surface coating once trapped in the clamp can only be removed by applying a traction which has the effect of reinforcing the force of

  retention of the clamp and risk of tearing the surface coating.

  The present invention therefore aims to overcome this major drawback by proposing a fastening profile for surface coating allowing rapid installation, change and movement of the surface coating, simple and without risk of deterioration of the surface coating during its disassembly or readjustment, while providing effective surface coating that is proportional to the tension of this surface coating once in a while, as well as

  aesthetic enhanced once the surface covering has been laid and stretched.

  For this purpose, the invention relates to a fencing profile for surface coating such as defined in the preamble, characterized in that at least said movable chewing piece has an extension folded inwards of said longitudinal groove , this extension forming an elastic tongue subjected to a restoring force tending to press it against said fixed jaw and defined with it an acute angle, including

  between 10 and 80 degrees and, preDérence, equal to 45 degrees.

  According to a first preferred embodiment, said fixed jaw is disposed

  substantially parallel to said support plane.

  According to a second preferred embodiment, said fixed jaw is oriented

  substantially perpendicular to said support plane.

  The fixed jaw is advantageously extended by an extension oriented towards

  said elastic tongue and forming a support jaw.

  Preferably, the elastic tongue has a thickness less than that of said fixed jaw and, opposite said fixed jaw, a bearing face on the

less partially smooth.

  The free end of said elastic tongue may be provided with a longitudinal spout

oriented towards said fixed jaw.

  In an alternative embodiment, said fixing profile comprises two longitudinal channels each terminated by a clamp formed by a movable jaw and a fixed jaw, arranged near the opposite longitudinal edges of said fixing profile and for example oriented substantially perpendicular to one another. The profile may include a front wall having a V-shaped shape defining a longitudinal reinforcing rib and at least one longitudinal recess

  relief and fixing holes used for fixing to said support wall.

  Said fixing profile is advantageously made in one piece by extrusion of a material chosen from the group comprising at least aluminum, alloys

  aluminum, plastics.

  The present invention and its advantages will appear better in the following description

  of an exemplary embodiment, with reference to the accompanying drawings, in which: - Figures 1A, 1B and 1C are sectional views of three fixing profiles for surface coating according to the invention, Figures 2A and 2B are perspective views illustrating the fixing of the profiles of FIGS. 1A and 1B on their support wall, FIGS. 3A and 3B are perspective views illustrating the method of placing a surface coating in the fixing profiles of FIGS. 2A and 2B, - Figures 4A and 4B are perspective views illustrating the surface coating after it is tensioned in the fixing profiles of Figures 3A and 3B, and In Figures SA and 5B are perspective views illustrating different modes

  of use of the fixing profiles of FIGS. 1A and 1B.

  With reference to the figures, the present invention relates to a fixing profile 1a, 1b, 1c for a surface covering 2a, 2b flexible and stretched for false ceilings and wall decoration intended to be clad and fixed to a support wall 3. The profile of fixing la, lb, lc comprises a support plane P pressed against the periphery of at least one S support wall 3, corresponding either to the wall to be covered or to a wall adjacent to the wall to be covered, on which the profile of fixing la, lb, lc is fixed so as to maintain at least one peripheral edge of the surface covering 2a, 2b and at

  allow its homogeneous tensioning.

  Figures 1A, 1B and 1C show three embodiments of a fixing profile la, lb, lc consisting of a single piece obtained by extrusion of a material such as aluminum, aluminum alloys or, synthetic materials such as PVC. This fixing profile la, lb, lc is designed to meet all the installation configurations of a stretched suspended ceiling or a wall decoration such as

1S explained later.

  In reference to FIGS. 1A and 1B, the fixing profile 1a, 1b has a non-symmetrical section which fits approximately in a right triangle and comprises at least one back wall 4a, 4b and a front wall 5a, 5b. The back wall 4a, 4b is for example planar to form, at least in part, the support plane P of the fixing profile 1a, 1b. The front wall 5a, Sb extends opposite to the back wall 4a, 4b and can consist of several sections of different orientations, connected to each other by angular zones. In these examples, the back wall 4a, 4b and the front wall 5a, 5b substantially form a Y. The fixing profile 1a, 1b has a longitudinal groove 6a, 6b intended to receive the edge of a surface coating (not shown in these figures). This longitudinal groove 6a, 6b is preferably located near one of the edges

  longitudinal of the fixing profile la, lb. So, as the description details more

  far, when the surface covering is in place, the fixing profile 1a, 1b is largely concealed by the surface covering. The longitudinal groove 6a and 6b is terminated by a clamp formed by a fixed jaw 13a, 13b and a movable jaw 11a, 11b arranged opposite one another and cooperating with each other to maintain by pinching the surface coating when it is engaged in the

longitudinal groove 6a, 6b.

  The movable jaw 11a, 11b has an extension of reduced thickness folded towards the inside of the longitudinal groove 6a, 6b. This pro lo nment forms an elastic tongue 12a, 12b having at least one bearing face 14a, 14b disposed opposite the fixed jaw 13a, 13b. The elastic tongue 12a, 12b is supplied with a restoring force which tends to press it against the fixed jaw 13a, 13b defining a pinching zone Z. The bearing face 14a, 14b may be partially flat and smooth and include, at its free end, a longitudinal spout oriented towards the fixed jaw 13a, 13b and which contributes to maintaining the surface coating in the pinching zone Z. The fixed jaw 13a, 13b of the fixing profiles 1a, 1b is oriented respectively substantially parallel and substantially perpendicular to the support plane P. In these two cases, the elastic tongue 12a, 12b defines with the fixed jaw 13a, 13b an acute angle a1, a2, generally between 10 and 80 degrees. This angle a1, a2 is preferably equal to 45 degrees. Indeed, an angle al, a2 too open will make the insertion of the surface coating 2a, 2b difficult. Similarly, an angle al, a2 that is too closed would reduce the elastic effect of the elastic tongue 12a, 12b and therefore decrease the retaining force in the pinching zone Z. In addition, with an angle al, a2

  too closed the bracing effect would be more difficult to obtain.

  The fixed jaw 13a, 13b may include an extension folded inwards from the longitudinal groove 6a, 6b substantially perpendicular to the elastic tongue 12a, 12b. This extension forms a support jaw 15a, 15b for the elastic tongue 12a, 12b. The elastic tongue 12a, 12b and the support jaw 15a, lSb delimit a V-shaped introduction zone whose point corresponds to the pinch zone Z in which the surface coating 2a, 2b is held once engaged the longitudinal groove 6a, 6b. This support jaw 15a, 15b is preferably substantially

  perpendicular to the elastic tongue 12a, 12b, but can be oriented differently.

  If the angle f1,, B2 which it defines with the fixed jaw 13a, 13b is too open, the introduction of the surface coating 2a, 2b is made difficult. An angle, B1, p2 too closed will not allow the surface coating 2a, 2b to penetrate sufficiently

  far into the longitudinal groove 6a, 6b to guarantee its good insertion.

  The fixed jaw 13a, 13b comprises at least one, and in the examples illustrated by FIGS. 1A and 1B, two longitudinal protuberances forming teeth oriented towards the bearing face 14a, 14b and arranged so as to oppose the outlet of the surface coating 2a, 2b engaged in the longitudinal groove 6a, 6b. These longitudinal protrusions can have different profiles and form between them

longitudinal grooves.

  The fixing profile 1a, 1b also includes a longitudinal recess 8a, 8b making it possible to lighten its structure and reduce its material cost. This longitudinal recess 8a, 8b is separated from the longitudinal groove 6a, 6b by a longitudinal rib 9a, 9b reinforcing the structure of the fixing profile 1a, 1b. The number of longitudinal recesses 8a, 8b and longitudinal ribs 9a, 9b

  is obviously not limited.

  FIG. 1C illustrates an alternative embodiment of a fixing profile lc which combines the two profiles 1a, 1b. This lc mounting profile is versatile and allows

  use in various mounting configurations.

  The fixing profile lc has a non-symmetrical section which fits approximately in a rectangle and comprises at least one support plane P formed by a back wall 4c, a front wall Sc and two longitudinal grooves 6a, 6b provided along the edges of the fixing profile lc, these longitudinal grooves 6a and 6b being respectively terminated by jaws lla, 13a, llb, 13b for holding the surface covering (not shown in this figure). The longitudinal grooves 6a and 6b are located on the opposite edges of the fixing profile lc, oriented substantially perpendicular to each other and formed like those illustrated in FIGS. 1A, 1B and previously described. They thus allow the mounting of the fixing profile lc on a support wall, as close as possible or at a certain distance from the wall to be covered, this wall to be covered being vertical or horizontal

  and corresponding to the support wall or to an adjacent wall.

  In this alternative embodiment, the back wall 4c and the front wall 5c extend between the two longitudinal grooves 6a, 6b. The front wall 5c is arranged opposite the back wall 4c and can be made up of several sections of different orientations connected to each other by angular zones. In this example, the two central sections form a longitudinal V-shaped rib, reinforcing the structure of the fixing profile lc, the point of which is located at the dorsal wall 4c. This

  fixing profile lc also includes two longitudinal recesses 8a, 8b.

  The fixing profile la, lb, lc may include through holes (not shown) for fixing it to the support wall, for example by means of staples, screws, nails. The fixing profile 1a, 1b can also be fixed to the support wall by

  bonding or by any other equivalent means.

  The fixing profile 1a can be mounted, as illustrated in FIG. 2A, on a support wall 3, for example a wall, this support wall 3 being adjacent to the wall to be covered, for example a ceiling. This configuration is very advantageous by

  example for covering ceilings that you want to lower.

  As illustrated in FIG. 2B, the fixing profile 1b can be mounted on a support wall 3, for example a plate, corresponding to the wall to be covered. This configuration is also very advantageous since it allows that only the wall to be covered has fixing means, leaving the adjacent walls free of

all perforations.

  It is obvious from reading this description that the fixing profiles 1a, 1b,

  They can be used as desired to cover the support wall 3 or an adjacent wall and that they can be fixed to this support wall or to an adjacent wall. The fixing profile lc can be mounted in these two configurations and cooperate with other fixing profiles fixed on the support wall 3 or on adjoining walls. The laying distances dl, d2 separating the different fixing profiles of the wall to be covered and / or of the support wall 3 can vary. Thus, we can for example respect different distances dl allowing the installation of a surface coating 2a, 2b not parallel to the surface to be covered. In particular, the fixing profile la, lb, lc can be fixed, for example obliquely, so that the distance dl, d2 separating it from the adjacent wall is variable over its length or, different

from one wall adjacent to the other.

  By way of nonlimiting example, the surface coating 2a, 2b can be made of polyester coated with polyurethane which is the subject of patent application FROO / 14156, delivered in a roll, and cut to the appropriate dimensions to form a sheet adapted to the wall. to cover. This type of surface coating 2a, 2b has the particularity of shrinking with heat. The use of a heat source such as a heat gun will allow rapid retraction not requiring manual, long and painful tensioning of said surface coating 2a, 2b. This surface coating 2a, 2b also has the advantage of being impermeable to dust, of being washable, and of being able to be painted with any commercially available paint. In addition, it has a mechanical resistance up to fifteen times greater than that of PVC surface coverings and may include, in different places on its covering face, cutouts forming decorative patterns, holes allowing the installation of spotlights. lighting, etc. Advantageously, the introduction of flame retardant into the composition of the polyurethane coating will allow the coating to

  surface 2 to be classified as fire class M1.

  A method of fixing the surface covering 2a, 2b in the fixing profile 1a, 1b is now described with reference to FIGS. 3A, 3B and 4A, 4B, which respectively illustrate the insertion of the surface covering 2a, 2b into the fixing profile 1a, 1b and, the surface covering 2a, 2b stretched over the fixing profile 1a, 1b. Once the fixing profile 1a, 1b mounted on the support wall 3, the surface coating 2a, 2b can be inserted into the groove 6a, 6b. To do this, it is manually presented in front of the introduction area. The insertion is then carried out using a tool chosen from the group consisting of at least one spatula, a screwdriver, a

  squeegee. In the description which follows, we will use in a nonlimiting manner the

  spatula term 17 to designate this tool. Using this spatula 17, the operator forms a fold in the surface coating 2a, 2b and then presses the spatula 17 in the direction of the longitudinal groove 6a, 6b so as to spread the elastic tongue 12a, 12b from the jaw. support 15a, 15b in the direction of the movable jaw 11a, 1b, then inserting the surface coating 2a, 2b into the longitudinal groove 6a, 6b. The elasticity of the elastic tongue 12a, 12b allows it to deform to let the spatula 17 pass surrounded by the surface coating 2a, 2b being housed in the groove

longitudinal 6a, 6b.

  The operator removes the spatula 17 from the longitudinal groove 6a, 6b. During this removal, the elastic tongue 12a, 12b returns to the initial position by pressing on the surface covering 2a, 2b, thus maintaining it in the pinching zone Z between the tongue

  elastic 12a, 12b and fixed jaw 13a, 13b.

  s The greater the thickness of the surface coating 2a, 2b, the greater the pressure applied by the elastic tongue 12a, 12b to it. The fold formed in the surface coating 2a, 2b during insertion, separates the useful surface coating surface 2a, 2b from the free surface 7a, 7b. After insertion of the surface coating 2a, 2b this free face 7a, 7b remains accessible outside the fixing profile la, lb, lc. Thus if it is necessary to move the surface covering 2a, 2b, it is possible to pull this free face 7a, 7b in a direction substantially parallel to the elastic tongue 12a, 12b. This traction allows the free face 7a, 7b to slide between the jaw 13a, 13b and the useful face of the surface covering 2a, 2b until the fold formed by the surface covering 2a, 2b is extracted from the pinching zone Z. The surface coating 2a, 2b can be replaced in the fixing profile 2a, 2b as well as in the other fixing profiles fixed at the periphery of the wall to be covered so that its peripheral edges are maintained. The useful face of the surface covering 2a, 2b then covers the major part of the fixing profile 1a, 1b, so that only the edge of the fixed jaw 13a, 13b appears. The fixing profile 1a, 1b thus concealed is discreet and makes it possible to guarantee the aesthetics and the

  finishing, for example of the false ceiling.

  When tensioning the surface coating 2a, 2b, the latter wraps around the elastic tongue 12a, 12b. The traction applied in the pinching zone Z has the effect of causing an bracing of the elastic tongue 12a, 12b on the support jaw 15a, 15b. This bracing makes it possible to increase the holding force of the clamp in proportion to the tension of the surface covering 2a, 2b. The tension of the surface coating 2a, 2b can be obtained, advantageously, by heat-shrinking when the surface coating 2a, 2b is made of polyester coated with polyurethane. For the other types of surface coatings, the tensioning of the surface coating is obtained, for example, using the spatula 17 with which the surface coating is pushed into the longitudinal groove or grooves 6a, 6b up to at sufficient tension or after

  cooling when the surface coating 2a, 2b is applied hot.

  After fitting and tensioning the surface covering 2a, 2b, the free face 7a, 7b can be cut flush with the fixing profile 1a, 1b using a blade and inserted into the

  longitudinal groove 6a, 6b to no longer be visible.

  To disassemble the surface coating 2a, 2b, the free face housed in the longitudinal groove 6a, 6b will be extracted at one of the ends of the fixing profile 1a, 1b using for example a screwdriver. Then, as for moving the surface coating 2a, 2b, this free pan will be extracted from the longitudinal groove 6a, 6b, and will allow after traction to remove the surface coating 2a, 2b, over all or part of the length of the profile of fixing la, lb. The installation, tensioning and dismantling of one or more surface coverings 2a, 2b in a fixing profile lc are not shown but can be carried out in the same way as for the fixing profiles la, lb in using one or

  the two grooves s longitudinal n 6a, 6b.

  Another mode of use of the fixing profile 1a, 1b is illustrated by FIGS. 5A, B in which it allows two surface coatings 2a, 2b to be maintained. The - fixing profile 1a of FIG. 5A is fixed on a beam 10 integral with the support wall 3, for example a ceiling, and the fixing profile 1b is fixed on the wall to be covered. These configurations are very advantageous and allow the covering of very large walls and / or the simultaneous use of surface coatings 2a and 2b different, for example in their nature, composition, visual appearance, color, etc. In these two configurations, the fixing profile 1a, 1b is completely covered by the surface coatings 2a, 2b and is no longer visible. During assembly, the edges of the two surface coverings 2a and 2b are introduced simultaneously or successively into the groove 6a, 6b and retained by the clamp before being stretched in directions, for example opposite 01 and 02. Removal of the coverings 2a, 2b is obtained by simultaneous or successive removal of the two

surface coatings 2a, 2b.

  Depending on the configuration of the wall to be covered, of the support wall (s) and of the adjacent walls, it is possible to use the various fixing profiles 1a, 1b, 1c in a combined manner. The orientation of the longitudinal grooves 6a, 6b of the fixing profile 1c allows, while using only one type of fixing profile 1c, to choose the orientation of the fixed jaw 13a, 13b most suited to the configuration of the premises and thus offers a multitude of possibilities of arrangement of the surface coating 2a, 2b. The fixing profiles la, lb, lc can be used on various support walls 3 such as plaster, plasterboard (, wood, concrete, ... Insulation panels, for example soundproofing, can be placed on the wall to be covered before the installation of the surface coating 2a, 2b. Likewise, a heating device, for example by heating resistors, may be installed on the wall to be covered and concealed at

  the rear of the surface coating 2a, 2b.

  The fixing profiles la, lb, lc can be tinted during their manufacture and include a decorative frieze, for example along the fixed jaw 13a, 13b so as to be visible after the laying and tensioning of the surface covering

2a, 2b.

  This description clearly demonstrates that the invention achieves all of the

  fixed objectives, in particular that the installation of the surface coating 2a, 2b is clearly facilitated and that the retaining force of the fixing profiles la, lb, lc is excellent. Of course, the present invention is not limited to the embodiments described but extends to any modification and obvious variant for a

skilled in the art.
