Description

"Methods, device, and spatula for mounting
a panel and fix a hanging or the like "
DESCRIPTION
The present invention relates to a method for fixing a curtain or similar covering, in particular a wall covering.

 The present invention also relates to a method for mounting a panel of finishing work in the building industry, with subsequent installation of a curtain or similar covering, in particular wall covering.

 The present invention also relates to a profiled device for implementing the above methods.

 The present invention also relates to a spatula which can be used as a tool for implementing the above methods.

 In the building industry, in particular the finishing industry for professional premises and the like, such as office buildings, difficulties arise when the client requires decoration by drapery, most often made of textile material. While most finishing operations, including the installation of panels, bay windows, doors etc. can be prepared in the factory to the point that only simple operations are necessary on the construction site, the installation of the drapes remains a source of hazards and additional cost. The exposure time is relatively long, adjustments are difficult, tension defects can appear, with the formation of folds. There may also be horizontal defects when the drapery has patterns. In case of faulty installation, there is a risk that the corresponding fabric is lost.

The same difficulties will recur if the user of the premises wants to change the drapes after a certain period of use. Similar difficulties will arise when the partitioning of the premises is of the mobile type and the user wishes to modify the arrangement.

 FR-A-2 675 180 and 2 682 707 are in particular known for profiles making it possible to pinch a curtain edge between at least one lip of this profile and a surface of the building, for example a ceiling surface, of soil, etc. This device is a delicate implementation because it requires that the profile is placed with precision relative to the building surface in question. On the other hand, we do not control the qualities of friction between the drapery and this building surface. In addition, there is not always a building surface which is suitably located to be opposite a profile fixed under the edge of the curtain.

 The aim of the present invention is to propose methods and devices facilitating the installation of draperies and similar coverings, improving the result obtained, facilitating the removal and the refitting and offering new possibilities with regard to the use of draperies as interior lining of the walls. of building.

 According to a first aspect of the invention, the method for fixing a curtain or similar covering, in particular a wall covering, is characterized in that an edge of the curtain is engaged in a cage having an insertion slot delimiting the surface to be covered, so that the edge of the curtain is retained by clamping and / or friction in said cage.

 By placing the cage so that the insertion slot is along the desired limit for the surface to be coated, the curtain can be fixed by inserting the edge of the curtain in the cage regardless of the environment and in particular the surfaces available near that to be coated. In addition, the tightening and therefore the retention of the edge of the curtain is carried out in a cage specially provided for this purpose and which can therefore be arranged in an optimal manner for the retention of the edge of the curtain. The good fixing of the edge of the hanging is thus independent, once again, of the surfaces surrounding the hanging.

 I1 is possible to make the cage so that the curtain is held firmly when it is subjected to its own tension while being easy to release by applying a suitable force, in particular a force perpendicular to the plane of the covering and applied from a corner of the curtain, so as to release the curtain gradually from one end of the cage to the other end of the latter.

 The operations of removal and installation, or readjustment are therefore facilitated.

According to another aspect of the invention, the method for mounting a panel of finished work, comprising the following steps
- installation of at least one support profile
- installation of the panel so that a rear face of a
edge of the panel rests on a retaining face
of the support profile
- fixing of a locking profile on the
holding profile so that one side of
locking of the locking profile comes
lean on a front face of the edge of the panel
- installation of a curtain or similar covering on the
sign,
is characterized in that when the locking profile is fixed, the locking profile is placed so that it contributes to defining, with the retaining profile, a cage having an insertion slot, and in that for placing the curtain or similar coating, an edge of the curtain is engaged in the cage so that the edge of the curtain is retained by clamping in said cage.

 Thus, the cage is defined jointly by two profiles. The cage can thus be produced by very economical means such as aluminum extrusion, while presenting a very narrow insertion slot, of the order for example of a millimeter or a millimeter and a half. Such a slot can hardly be obtained by extrusion of a one-piece profile. I1 is better to use two profiles each defining one of the edges of the slot.

Thanks to the invention, one of the elements constituting the cage is a panel locking element, which is in any case necessarily attached, in order to lock the panel after its positioning. Therefore, the cage, although made from two profiles, is achievable without any additional profile compared to the number required to support the panel.

 According to a third aspect of the invention, the profiled device for the finishing work in the building, suitable for fixing a curtain or similar covering, in particular wall covering, is characterized in that it comprises autonomous means for retaining an edge of the curtain at the surface limit to be coated, these means comprising a cage having an insertion slot by which an edge of the curtain can be pressed into the cage and be retained there by tightening and / or friction.

 By "autonomous" means means capable of retaining the edge of the curtain themselves, without cooperating with, for example, a building surface such as a ceiling surface.

 According to a fourth aspect of the invention, the spatula, in particular for the implementation of a method according to the first aspect, is characterized in that it has a blade having an active curved convex edge, preferably connected to an edge lateral by an angle.

 To insert the edge of the curtain in the cage, we use the convex curved edge which is able to push the curtain through the insertion slot of the cage without an angle of the blade may damage the curtain. An angle can nevertheless be provided on one side of the blade, to complete the insertion at each corner of the periphery of the curtain.

 Other features and advantages of the invention will emerge from the description below.

- Figure 6 is a horizontal sectional view
partial of another mode of implementation of
the invention.

 In the example shown in Figure 1, a movable partition taken as an example of a finishing work in a building such as an office building, comprises an opaque upper part 1 and a lower part 2 forming picture window. The upper part 1 comprises two panels 3 such as cardboard plaster, arranged parallel to each other, and each comprising on its face facing the other panel an insulating lining 4. The panels 3 are held at a certain distance from each other by a ceiling connection structure 6 and along the lower edge by a structure 7 forming a bay frame, further having the function of keeping two transparent panels 8 apart from each other bay window 2.

 For the lower part of the partition, not shown, one can imagine an arrangement completely symmetrical to that of FIG. 1, with the lower part of the bay frame supporting the upper edge of an opaque part also held, along its lower edge, by a structure connecting to a building floor.

 In this example, we are looking for a particular aesthetic effect consisting of the fact that the panels 3, covered by a drapery 9 displayed by a strong mixed line with double dashes, protrude relative to the ceiling connection structure 6, which is nevertheless visible. over a certain height H from the ceiling 11.

 But the invention is applicable outside of such aesthetic research. In particular, in the example of FIG. 1, the lower edge of the panels 3 does not protrude relative to the picture window 2.

 In the example shown, the ceiling connection structure comprises a central section 12 fixed to the ceiling by any means not shown, and supporting on each side a strip 13 made for example of wood. The lower edge of each strip 13 is fitted into a groove in a rigid retaining profile 14, produced for example from aluminum profile. The groove of the retaining profile 14 is defined by a bottom 18, a rear wing 16 extended beyond the bottom 18 by a wing 17 having a face 17a for holding the insulating lining 4, and a front wing 19 whose front face 19a maintains the rear face 21 of the upper edge of the corresponding panel 3.

 In the following, for each panel, we qualify as "rear" and respectively scholarly "the orientation towards the other panel and respectively opposite to it.

 At its end opposite the bottom 18, located beyond the edge 22 of the panel 3, the retaining wing 19 carries three fins 23, 24, 26 directed towards the front, and forms with them a substructure 25 (see also figure 2). The proximal fin 23 is adjacent to the edge 22 of the panel 3 and contributes, with similar means along the other edges of the panel 3, to immobilize the panel 3 against movement in its own plane.

 The proximal fin 23 and the middle fin 24 define between them a locking cavity into which a locking profile 27 can snap. The locking profile 27 has two ribs 28, capable of engaging together between the fins 23 and 24. Each rib 28 carries on its face opposite to the other rib 28 a snap-fit spout which snaps behind a corresponding projection of the adjacent fin 23 or respectively 24.

 The median fin 24 and the extreme fin 26 form between them, with a bottom 29 constituting the terminal end of the wing 19, the body of a cage 31 retaining the edge of the curtain 9. The cage 31 carries inside it rigid retaining ribs 32 formed in one piece on the inside face of the end fin 26. The middle fin 24 carries on its face turned towards the inside of the cage 31 a recess 33 forming a slide intended to be received by longitudinal sliding, before mounting the profile 14, the sole 36 of a strip of deformable material 34. The sole 36 carries on its face facing the inside of the cage 31, two oblique retaining lips 37, directed obliquely towards the bottom 29 and towards the retaining projections 32. The strip 34 is produced in a known manner with a synthetic material having a greater hardness in the sole 36 than in the oblique lips 37. The lips 37 are therefore more deformable than the week it 36, but are nevertheless qualified as wsemi-rigid. In particular, they have sufficient resistance to the tensile forces which the drapery can undergo once mounted.

 The locking profile 27, shown in phantom in Figure 2, comprises a locking wing 38 which comes to bear by a locking face 38a against the front face 39 of the edge of the panel 3 to immobilize the panel 3 against of any displacement transverse to its own plane. The locking profile 27 further comprises, in the extension of the locking wing 38 and on the other side of the ribs 28, a closing wing 41 which completes the cage 31 by almost completely closing the opening that the fins 24 and 26 define between them on the side opposite the bottom 29. The closing wing 41 of the locking profile 27 leaves, however, between its free edge and that of the extreme fin 26 an insertion slot 42. The lips 37 of the strip 34 are higher than the protrusions 32 of the end fin 26 so as to form between the protrusions 32 and the lips 37 a passage roughly aligned with the insertion slot 42 (see Figure 1).

 We will now describe with regard to the upper region of the partition, the method of installing a panel and subsequent installation of the drapery.

 After setting up the structure 6 for connecting to the ceiling 11, supported for example by pillars not shown, the retaining profiles 14 are fitted onto the lower regions of the strips 13, after having placed a strip 34 in each profile 14. , a panel 3 with lining 4 is put in place for each profile 14 so that the lining 4 bears against the retaining face 17a. The rear face 21 of the panel, in a region adjacent to the edge 22 and stripped of the lining 4, bears against the holding face 19a.

The locking profile 27 is then put in place by snapping on the ribs 28 between the fins 23 and 24 of the profile 14 so as to close the cage almost completely.

 FIG. 3 represents the panel 3 and the lining 4 put in place relative to the retaining profile 14 adjacent to the upper edge 22 of the panel 3, and to an identical retaining profile 44 along one of the vertical edges of the panel 3. FIG. 3 further shows the upper locking profile 27 and an identical locking profile 47, ready to be snapped into the holding profile 14 and into the lateral holding profile 44 respectively. At the corner of the panel 3, the retaining sections 14, 44 and locking 27, 47 are cut at a tab at 450 so as to be joined together.

 Then, as shown in Figure 4, there is presented facing the assembly made the drapery 9 having, beyond a broken line 48, an edge 49 intended to be engaged in the cage 31. When applying the drapery 9 against the panel 3, the drapery 9 covers the panel 3 and all of the locking profiles 27, 47, the line displayed by the dashed line 48 coming to be superimposed on the insertion slot 42. Then, using a spatula 51, the edge 49 is engaged in the cage 31 of the sections 14 and 44 respectively, in a direction which is perpendicular to the plane of the visible part of the drapery 9. Thus, the edge of the introduction slot defined by the wing 41 of the locking profile 27 forces the drapery 9 to form an angle at 900 between the visible part and the hidden edge 49. This results in friction which makes the tension of the visible part of the drapery 9 only partially transmitted inside the cage 31. This contributes to the stability of the hanging attachment. In addition, the lips 37, thanks to their inclination, facilitate the introduction of the edge 49 but resist by arching the extraction of the edge 49.

 The spatula 51 is more particularly viewed in FIG. 5. It comprises a blade 52 having substantially the shape of a quarter of an ellipse or of a quarter of a circle. The blade has an edge 53 adjacent to a frame 54, a lateral edge 56 perpendicular to the edge 53 and a convex curved edge 57 extending between the ends distant from each other from the edge 53 and respectively from the lateral edge 56. The curved edge 57 forms a substantially right angle 58 with the lateral edge 56. In order not to risk damaging the hanging, the edges 56 and 57 of the blade 52 are not sharp and the angle 58 is slightly rounded.

 The use of the spatula 51 is displayed at the top left of FIG. 1 where we see the blade 52 pushing the edge 49 of the curtain 9 into the cage 31. To perform this operation, the curved edge 57 is preferably used ( figure 5) of the spatula. In this case, the slot 42 for introduction into the cage is positioned as shown by the dashed line in Figure 5, the angle 58 remaining outside the cage. There is thus no risk of damaging the curtain during the insertion of the edge 49 into the cage. The angle 58 of the spatula is useful for completing the insertion at each longitudinal end of the cage, that is to say for example in the angle between the sections 14 and 44 in FIG. 4.

 The edge 49, once inserted into the cage 31, is entirely concealed in the latter as shown in the upper right part of FIG. 1. The slot 42 for introduction into the cage 31 then marks the limit between the extent covered by the wall covering 9 and the region left bare by the covering. As the slot 42 is at the angle between a front wall of the cage 31, constituted by the closing wing 41 situated in the plane of the hanging 9 and the fin 26 forming the outer wall oriented transversely to the plane of the hanging 9 , the covering 9 appears as if it were projecting from an underlying structure situated behind, visually materialized by the strips 13.

 In the case of an upper edge of hanging (Figure 1) the fin 26 forming the outer wall of the cage is located above the hanging 9, as shown in Figure 1. We can then fix a profile d 'hooking 61 above the cage. The profile 61 has an anchoring wing 62 inserted between the cage 31 and the strip 13, in a recess 59 formed in the rear face of the wing 19 behind the cage 31. A wing 63 of the attachment profile 61 rests on the extreme wing 26 of the cage 31. A rib 64 of the profile 61, positioned above the slot 42, forms a hook for suspensions 66 supporting, for example, paintings or other works of art 67.

 We will now describe the lower part of Figure 1, mentioning only the differences from the upper part.

 The frame 74, forming an upper element of the frame of the opening 2, defines the bodies of the two cages 31, one on each face of the partition. For reasons of extrusion technique, the frame 74 is produced by means of two extruded elements 76 and 77 snapped into each other. The element 76 carries the cage bodies 31 while the element 77 carries two wings 78 between which are clipped two corresponding ribs 79 of the locking profile 27. The latter comprises as in the preceding example a locking wing 38 to prevent the panel 3 and the lining 4 from moving away from a retaining wing 17 of the profiled element 77, and a closing wing 41 opposite the wing 38 and partially closing the corresponding cage 31. positioning of each panel 3 and then of the drapery 9 along the upper edge of the opening 2 is similar to that described above.

 In the example shown in FIG. 6, a frame 84 having a profile and a structure very similar to those of the frame 74 of FIG. 1 as regards the positioning of the panels 3, 4 and the drapes 9 constitutes a vertical pillar for a door frame 81. The positioning of the panels and draperies along this door frame is once again analogous to that described above.

 Figure 6 further shows that the invention allows the drapes 9 to follow without discontinuity both the outside and the inside of an elbow 82 of the partition.

A composite pillar defines this elbow. It includes two angles, for example made of wood, one 83 defining the convex outside angle, the other 86 defining the concave inside angle. The angle 86 comprises for each partition plane, a wing 87 engaged in a groove 88 defined by a pillar 89 of profiled aluminum located between the two angles 83, 86 and between the two parallel panels 3, 4 of a respective partition plane . The pillars 89 are for example fixed to the floor and to the ceiling of the room. The outer wing 89 defining the groove 88 carries a substructure 25 with three fins 23, 24, 26, identical to that described with reference to the upper part of FIG. 1. A locking profile 27 can be inserted between the fins 23 and 24 by snap-fastening to retain a panel 3, 4 against a wing for retaining wing 17 of the pillar 89 while the fins 24 and 26 define between them a cage 31 whose insertion slot 42 is located extremely close to the edge interior of the elbow 82. As this structure is produced on each side of this interior edge, two drapes 9a, 9b, each extending along one of the partitioning planes on the concave side of the elbow 82 can be placed so as to be almost joined along the inner edge of the elbow 82.

 On its side facing the outside of the elbow 82, each pillar 89 carries two fins 91 between which a locking profile 92 is snapped on.

Each profile 92 maintains against the pillar 89, on the one hand one of the wings of the external angle 83 and on the other hand one of the panels 3 with trim 4 on the side of the outside of the elbow. A single curtain 9c can bypass the outside of the elbow and in particular the angle 83.

 Of course, the invention is not limited to the examples described and shown.

 With reference to FIG. 1, it would also be possible for the cage to be formed on the retaining profile 14 so as to be generally pivoted by 900 relative to the example shown, in order to open towards the ceiling 11 with for example a insertion slot adjacent to the strip 13. In this case, the closing flange 41 of the locking profile 27 is extended by a wing 900 towards the strip 13 to close an upper opening of the body of this cage.

 One could provide in the cage, in place of the retaining projections 32, a second strip opposite to that shown.
