Description

PROFILES TO SUPPORT AND HOLD IN VOLTAGE
FALSE CEILING OR FALSE WALL
The present invention relates to profiles used to support and maintain in tension a false ceiling or a false wall made of a plastic sheet.

Generally the sheet of plastic material is stretched between two opposite edges that are substantially rectilinear, in particular between two walls to form a false ceiling. The plastic sheet is usually attached to a border that is both flexible and rigid, the cross section of which is in the form of a hook which engages on a shoulder produced on supports fixed directly to the walls or against the ceiling. .

It is known that numerous profiles, generally made of extruded materials, have been used as supports comprising a shoulder on which the edge of the plastic sheet is gripped. The cross sections of these borders have a few variations in their construction so as to ensure their attachment function. The cooperation, of the hook formed by the border, and of the shoulder formed on the profile makes it possible to support and keep in tension the false ceiling or the false wall.

The major difficulty, conditioning the design and production of the profile and the integral border of the plastic sheet, lies in the installation, hanging, tensioning of the false ceiling or false wall but also the stall when it turns out to be necessary.

Generally the material constituting the plastic sheet elongates when the temperature rises. This is the reason why on the one hand the dimensions of the false ceiling or false wall are, before installation, slightly smaller than the finished dimensions and on the other hand it is essential to strongly heat the false ceiling or the false wall during installation as well as the room in which one and / or the other must be installed.

The installation conditions are not very comfortable not only because of the high temperature of the room, but also because the operator, in particular for installing a false ceiling, is most often placed under this false ceiling to hang it on the profiles. fixed against the walls.

In order to facilitate the positioning of the border, certain profiles include, a rounded surface so that the border slides before becoming wedged (Patent FR-A 2,078,579), or cut sides capable of playing an equivalent role ( Patents FR-A 2,310,450 and FR-A 2,475,093).

Despite the flexibility of the border, it is generally difficult to engage the lip forming a hook over the entire length of the shoulder produced on the profile, it is therefore necessary to proceed gradually. To keep the edge in place on a certain section of the shoulder made on the profile before continuing on another section, it is generally provided for recesses on this shoulder so as to limit the length of attachment and to proceed in steps of about 20 cm (Patent FR-A 2,310,450) or about 12 cm (Patent FR-A 2,475,093).

To do this, as soon as the first section is engaged, it is essential to identify the recesses which are not visible when the operator is located below the profile. To avoid carrying out a preliminary identification or to proceed by trial and error, a device comprising a profile with a shoulder without removing it cooperates with a border forming a hook on which recesses are made similar to those practiced on the shoulder mentioned above (Patent FR-A 2,658 .849).

However, these recesses, in addition to weakening the profiles or the edge, require resuming machining after extrusion, a process generally used. Expensive operation which significantly increases the cost price of the profile or edge.

Furthermore the profiles are more or less spaced from the surface of the wall on which they are fixed so that either their dimensions or this spacing are unsightly. For this purpose, one of the proposed profiles has a shoulder in its lower part capable of providing a drop shadow and which can serve as a picture rail (Patent FR-A 2,078,579).

Also for aesthetic reasons it is possible to place in the lower part of the profile fixed against the wall a compensation profile obscuring the attachment system of the border fixed by bracing between profile and its shoulder (Patent FR-A 2.624.167 ).

Generally to cover the entire surface of a ceiling or wall, these false ceilings and false walls are made of several strips welded by high frequency currents.

When the surface is not too large, the tension of the plastic sheet is sufficient to prevent the material's own weight, although low per square meter, from creating a significant deflection in the center of the part.

For large areas and to avoid this unsightly deflection, it is necessary to fix to the ceiling, in the middle position, profiles forming intermediate supports to which are hooked the edges of two adjacent strips secured to the edges forming hooks.

However, the profiles used are generally variants of the profiles used for fixing against the ceiling and allowing the attachment of two edges (Patents FR-A 2,078,579, FR
A 2.310.450).

These types of profiles serving as intermediate supports generally fixed in the middle of the room can be considered unsightly. This is one of the reasons why it is proposed to use the joining of the strips to ensure the suspension of the plastic sheet on the ceiling. This solution also makes it possible to mount a false ceiling according to the profile of the ceiling itself when the latter is not perfectly horizontal or when its profile is in a broken line, in particular for attic roof spaces (Patent EP 0.137.086).

Other solutions combine aesthetics with the need to fix the false ceiling in the center of the room and offer profiles suitable for fixing them against the wall, ceiling or serving both to maintain the edge of a false ceiling and a false wall thereby hiding the profile.

To do this, the border is fixed by bracing using a simple spatula, covers or hubcaps are fixed by clips on the profiles (Patent EP 0.338.925).

All the proposed profiles are generally expensive either because they require a resumption of machining to carry out a recess necessary for the installation of the false ceiling or the false wall or because each made for a specific use it is necessary to have several types of profiles for a specific use. To produce profiles at competitive prices, most manufacturers offer plastic profiles. These profiles weakened by recesses are less rigid than extruded light alloy profiles. In addition, their paint is difficult to hang on the plastic and requires rework during flaking occurring as a result of adjustments necessary for installation. Whatever the system for hanging the border used, using a hook and dimples or a bracing system on the shoulder, the laying operation remains delicate if only because of the fragility of the plastic sheet but also the laying conditions, in height most often and at high temperature.

If the installation operation is still delicate, the removal required by maintenance or repair operations, in particular during repairs to the electrical installation, water supplies, heating, air conditioning, is otherwise more difficult. This is in fact to unhook the edge of the shoulder on which it is stowed without damaging the plastic sheet.

The poses and removals are made more difficult when the design of the profiles makes it difficult to introduce spatula blades to carry out these operations, especially at the edge of walls.

For aesthetic reasons, it is necessary to fix the false ceiling in the center of the room using very narrow symmetrical profiles. Another solution is to cover the profile with the plastic sheet, leaving the smallest possible gap between the plastic sheets laid edge to edge. This so-called "invisible profile assembly" solution involves specific profiles allowing installation and removal operations in good conditions, which is rarely offered and which discredits this type of profile.

In addition, from a decorative point of view, it may be advantageous to combine these types of false ceilings or false walls with parts of the ceiling or wall made up of panels or boxes of different materials such as paneling, glass or different uses such as light fixtures. What the profiles reserved for false ceilings and false walls generally do not provide.

Without calling into question the installation conditions, the present invention proposes to facilitate them and to overcome the drawbacks mentioned above.

The subject of the invention is precisely profiles to support and maintain in tension a false ceiling or a false wall consisting of a plastic sheet integral with a hook-shaped border, said profiles fixed to the ceiling or to the false wall include a cavity closed in the upper part, open downwards to allow the insertion and the housing of the border, delimited laterally by two vertical wings, one of which has a horizontal shoulder used for hooking the hook which overcomes the drawbacks of the prior art.

According to the invention, the profiles comprise a second cavity closed downwards by a substantially horizontal wing and laterally by two vertical wings so as to form a gor monkfish to channel a halyard, this latter cavity is contiguous to the previous one by a common wing and communicates with it in the upper part closed by a common horizontal wing, said sections include coupling means so as to produce a double section, suspended from the ceiling by a vertical core formed by the vertical webs of the sections, which are produced in the extension one or more vertical wings used for hooking the hook, uncoupled each of the profiles has assembly means making it possible to constitute a continuous stringer for supporting and maintaining the false ceiling or the false wall, which requires for to be hooked using the hook-shaped border the simultaneous cooperation of two s patules and to be unhooked the cooperation of a halyard previously housed in the cavity forming chute.

Preferably, the coupling means produced on the lower end of the vertical core of each of the profiles consist of shoulders forming a groove of straight U-shaped section open upwards for one and downwards for other so that these shoulders fit into each other to produce a double profile.

According to an advantageous arrangement, the coupling means produced on the lower end of the vertical core of each of the sections consist of symmetrical vertical shoulders held by the wings of a heald of straight U-shaped cross section, said heald threaded by a of the ends of the profiles rests on the part opposite the shoulders in order to produce a double profile.

According to a preferred embodiment, the coupling means produced at the upper end of the vertical webs of the profiles consist of a shoulder forming a groove of U-shaped cross section open downwards for one in which the web engages. vertical of the other profile.

Preferably also the coupling means produced at the upper end of the webs of the profiles consist of a horizontal shoulder produced on each of the profiles which are held by a smooth section of C section open downward, said smooth threaded by one end of the profiles allows the double profile to be suspended from the ceiling.

Thus the profiles coupled to keep suspended the false ceiling in the center of a room include means made in the lower part and upper part of the vertical webs of each of the profiles.

In the lower part two solutions are envisaged. A first solution consists of a shoulder on each of the sections, one open upwards the other downwards so that an interlocking can be achieved. Another solution uses a U-shaped heald threaded at the end of the profiles presented contiguous so as to keep them tight. The rail thus used can be made in one or more parts. The base of the U rests on the bottom of the cavity in which the vertical shoulders end. Depending on whether these shoulders are made directed downwards or directed upwards, the wings of the U to keep them tight will be oriented in the opposite direction upwards or downwards.

In the upper part two solutions are also proposed. A first solution consists in making a vertical shoulder on one of the sections in which the vertical core of the other section engages. In this case the coupling of the two profiles is obtained by introducing the vertical core of one of the profiles into the shoulder of the other then sliding the profile down so that the shoulders in the lower part can s' nest one inside the other. A second solution uses two horizontal shoulders held tight by a heddle threaded through one of the ends of the profiles. This stringer can be made in one or more parts.

Depending on the solutions adopted, the healds can be installed either indifferently by starting with one of the two when two healds are used in the upper and lower parts or after the shoulders in the lower part fit together.

Thus coupled and immobilized with respect to each other, they can form a crosspiece making it possible to support and keep the false ceiling in tension. These profiles are suspended using a tab or a clip resting on the shoulder of the upper end of the vertical core and connected to the ceiling by a chain or cable. In the configuration using a heald, judiciously arranged holes allow the attachment of the chain or cable.

According to an advantageous arrangement, the external faces of the shoulders made on the vertical webs of the profiles to ensure their coupling are each situated on a plane so as to allow their fixing against a wall or against a ceiling.

Preferably, the means of assembly of each of the profiles making it possible to constitute a smooth continuous edge are produced on the internal face of the vertical core by means of grooves serving as slides to a spacer intended to hold the different sections in place. of profiles arranged end to end or forming an angle between them.

According to an alternative embodiment, the vertical wing of the double profile used for hooking the hooks of the edges housed in each of the cavities and delimiting them is produced on one or the other of the profiles.

Each of the profiles can thus constitute a continuous edge rail fixed against a wall or against a ceiling. The grooves made on the internal face of each of the profiles make it possible to abut them more easily to each other or to connect them at an angle depending on the angle of the bearing surfaces.

Only identical profiles can be easily butted together. Indeed, except for the case of symmetrical profiles coupled with halyards threaded in the upper and lower parts of the vertical webs, the profiles, to be coupled, have different embodiments of shoulder shapes. Thus, depending on the configuration of the shoulders, a “male” profile will be discerned from a “female” profile.

The joining of sections using a spacer inserted in the grooves is therefore only possible between the same category of male-male or female-female profiles, the so-called symmetrical profiles then being classified in the "male" category. .

The joining of different categories is only possible by making up for the excess thickness resulting from the shoulders of the "female" profiles. This is possible by having a shim placed on the external face of the vertical core.

The vertical wing extension of the wing of the double profile on which the shoulders used for hooking the hooks are produced can be produced in different ways. The simplest solution is to have symmetrical profiles, in this case, each of the profiles will have a vertical wing with its shoulder. The other two solutions consist in producing a single vertical wing comprising two shoulders, this vertical wing common to the two sections is produced either on the "male" section or on the "female1 'section.

Although it is easier to constitute a continuous rail fixed against the wall or against the ceiling using the so-called symmetrical profiles, it is possible to constitute it with one of the "male" or "female" profiles provided with the wing with shoulders intended for hooking hooks.

However, when the wall or the ceiling has a sufficiently rough surface, it is still possible to use a profile which does not have a shoulder. In this case, the hooking of the hook against the ceiling or the wall is obtained directly by bracing the hook against the ceiling or the wall.

According to an advantageous arrangement, the hooking of the hook from the edge of the false ceiling or of the false wall on the shoulder of the vertical wing requires the simultaneous cooperation of two spatulas, one with a flat blade in the shape of a U '. another with concave blade fitting between the wings of the U of the flat blade spatula so as to introduce the edge into the cavity with the flat blade and hook the hook with the concave blade of the other spatula.

Preferably unhooking the hook from the edge of the false ceiling or false wall stowed on the shoulder of the vertical wing requires the cooperation of a halyard slipped between the shoulder and the hook at one end of the said profile halyard passed over the hook, rests and runs at the bottom of the chute to come out at the other end of the profile and be fixed on the horizontal wing delimiting the upper part of the two cavities so that by pulling on the free end of the halyard the hook is taken down step by step.

Without the cooperation of these two spatulas, it is practically impossible to hang the hook from the edge on the shoulder provided for this purpose, in particular at the edge of the wall, the travel of the spatula then being limited to 90 ".

If the attachment is deemed difficult, the removal would be more difficult without the use of the halyard provided for this purpose.

This halyard is installed when the profile (s) are applied against the wall, against the ceiling or fixed to the ceiling in the center of the room. It is attached to one end of the profile and runs through the chute.

The hanging of the false ceiling or false wall begins in principle with the end on which the halyard is fixed.

At the other end, the halyard is passed between the hook and the shoulder. A small end of the halyard then hangs from the profile.

Just wedge it against the wall or against the ceiling to make it invisible. Each section of the profile will have this halyard end. It is however possible to leave only one end as long as the halyard is housed in continuity in the different troughs formed by the corner connections of the various profiles. To avoid looking for the presence of the end of the halyard, it is possible either to make a marked plan or systematically to always put the halyard ends in the same place.

To proceed with the stall, it is enough to pull the halyard continuously, the hook has come out of the shoulder in the same way as one proceeds to set up a car windshield.

Without this halyard, it is not possible to unhook the false ceiling or the false wall without risking damaging it.

Preferably, the profiles are rectilinear and make it possible to assemble modules and / or boxes of variable geometries.

According to an alternative embodiment, they are bent along the plane of the vertical core so as to produce domes.

According to another variant, they are bent along a plane perpendicular to the vertical core so as to produce planar curves.

Although it is possible to connect profiles of different categories, given the choice offered by the different coupling modes, it will be easy to produce all polygonal geometric shapes such as rectangle, rhombus, trapezoid or even irregular figures.

These figures constitute modules or boxes which fit together. It is also easy to produce surfaces comprising both panels of stretched plastic sheets and panels comprising rigid coverings such as paneling, mirrors or other decorative patterns. These modules or boxes can be made before fitting together when it is a question of constituting the same row of panels.

However, it is always possible to couple the profiles beforehand so as to form modules or boxes and then hang the plastic sheet or lay any other rigid covering.

The use of symmetrical profiles makes it easier to assemble staggered panels.

By producing curvatures compatible with the mechanical resistance of the materials used to manufacture the profiles, it is possible to obtain panels of complex shapes bent along the plane of the vertical core. They will make it possible to produce domes, the coupling being able to be carried out after bending.

Curved along a perpendicular plane, they will make plane curves.

It will thus be possible to produce a hemispherical dome with cut sides.

FIGS. 1 and 2 show schematic sections of the profiles coupled in FIG. 1 and uncoupled in FIGS. 2.

The five wings delimiting the cavities 4 and 10 substantially arranged according to a Greek have rounded shapes not only to facilitate the production by extrusion of the light alloy profiles but to make it possible to ensure the various functions such as guiding and maintaining in position of the edge 3 so that its hook is well hooked on the horizontal shoulder 5a and such that the deployment of the halyard 15 in the cavity 10. This halyard 15 shown only in the lm profile exists in each of the profiles because it is essential for unhook the hook 3 from the shoulder 5a as described later. The shape of these shoulders 5a in arrowhead is justified for the following two reasons: to facilitate the introduction of the edge 3 into the cavity 4, the cutaway of the 'shoulder 5a serving as a slide, avoid a flat surface clearly more visible from below than a sharp edge. Although the distance between the edges 3 hung on each of the profiles is small, of the order of 3mm, it is desirable to make the appearance of the joint between two strips of the false ceiling 2 as discreet as possible, this is what which is obtained with this arrowhead profile of the shoulders 5a. The coupling of the profiles lm, 1f as presented in these figures is done as follows: assuming the profile 1f stationary, the profile lm is presented slightly inclined by so that the upper end of the core 13m fits into the open cavity towards the bottom of the shoulder 12f, the profile lm is then tilted towards the profile 1f so that the outer faces of the cores 13 are contiguous, the lm profile is then slid down so as to carry out the fitting of the shoulder llm into the shoulder llf. The two profiles are then coupled. They can be suspended from the ceiling by means of a 19f boom and a chain or cable. This continuous boom or made in different sections threaded by one of the ends of the profiles is maintained by leaning on the end of the shoulder 12f and on a boss made for this purpose.

After suspension from the ceiling of the profiles thus coupled, each comprising a nylon halyard 15 of 1.5 to 2 mm in diameter fixed to each of the ends of the profiles on the horizontal wing 9 using a knot, it is then possible to hang the edge 3 of the false ceiling 2 on the shoulder 5a using spatulas 16 and 17 as described later.

Each of the profiles can be used in the form of continuous edge rails to support the false ceiling 2 or the false wall.

The lm profile is then fixed against the wall of the wall or the ceiling by resting on the plane 20m constituted by the external face of the core 13m. Likewise for the profile 1f by resting on the plane 20f constituted by the external face of the shoulders llf and 12f. The different sections of the edge rail are kept assembled using spacers slid in the grooves 14m or 14f made on the internal faces of the cores 13. This assembly can be straight or angular.

In FIGS. 3 are shown in partial schematic views in section the different variants of the couplings of the profiles according to the invention.

FIG. 3a shows a coupling obtained in the lower part of the cores 13 by the interlocking of the shoulder llm in the shoulder 11f as described above.

In the upper part, a horizontal shoulder 12m is produced on each of the profiles. These profiles are kept assembled in the upper part by a 19m smooth C-shaped open downward. This continuous beam or made in several sections threaded through one of the ends of the profiles allows the profiles or ceiling to be suspended using a chain or a cable.

This coupling configuration avoids, as in the previous case, the need to tilt the lm profile in order to carry out the interlocking in the upper part.

In FIG. 3b, the assembly in the upper part is identical to the previous one, the coupling is carried out using a smooth 18 in the shape of a U open upwards, the wings of the U of which hold the vertical shoulders îîm produced on each profiles. This smooth 18 continues or produced in several sections threaded for one of the ends of the profiles is supported on the part opposite to the shoulders llm forming a cavity so as to strengthen the coupling of the profiles produced in the upper part by the smooth 19m.

Figure 3c is an alternative embodiment of Figure 3b wherein in the lower part-the shoulders llm are directed upwards and the wings of the U of the heddle 18 directed downwards.

In FIG. 3d, the nesting in the upper part is identical to that shown in FIG. 1, the nesting in the lower part is carried out in an identical manner to that of FIG. 3b. It could just as easily be identical to that of Figure 3c. This configuration avoids the need to tilt the lm profile to achieve the nesting in the upper part and therefore allows to adjust without significant play the nesting between the upper end of the core 13m in the shoulder 12f.

In FIGS. 4 there are shown in partial schematic sections variants of the attachment of the border 3.

In these cases, the wings 5 previously produced on each of the sections are replaced by only one.

In FIG. 4a, the common wing 5m comprising the shoulders 5a is produced on the profile lm, in FIG. 4b, the common wing 5f is produced on the profile lf. The nesting in the lower part is carried out using the shoulders llm and 11f produced on the profiles lm and lf, but could use the solutions of FIGS. 3c, 3d.

There is shown in Figures 5 schematic sectional views of the profiles applied against the walls or against the ceiling.

In FIG. 5a, the plane 20m constituted by the external face of the core 13m rests against the wall on which the profile lm is fixed with the aid of screws positioned between the assembly grooves 14m.

In FIG. 5b, the plane 20f constituted by the external face of the shoulders 11f and 12f bears against the wall on which the profile 2f is fixed using screws positioned between the assembly grooves 14f. The distance from the plane 20f from the external face of the core 13f requires the use of spacers 21.

In Figure 5c we show the use of a lm profile having no wing 5 as shown in Figure 4b. This profile is fixed to the ceiling using screws positioned between the 14m grooves. It suffices that the surface of the ceiling is sufficiently rough for the arcuate brim 3 to be hooked against the ceiling in the manner of the shoulders 5a described above. Although not shown, the halyard 15 is also previously housed in the cavity 10 serving as a chute.

In FIGS. 6 are shown in perspective views the spatulas 16 and 17 used for the establishment of the edges as shown in FIGS. 7 for the installation of a false ceiling. The flat blade spatula 16 has a U shape, the base of which is integrated into the handle. This spatula is used to present the border 3 in the cavity 4 as shown in FIG. 7a. To make this border penetrate into the cavity 4 it is necessary to use the spatula 17 with concave blade which is inserted between the wings of the U of the spatula 16. The two spatulas then operate simultaneously as shown in FIG. 7b. Continuing to push with the spatula 17 we manage to hang the edge 3 on the shoulder 5a of the profile lm. It suffices to proceed gradually to hang the edge on the shoulder of the profile as shown on the figure 7c.

In FIGS. 8 we show how the dropout of the false ceiling is operated. The halyard 15 is previously housed in the cavity 10. It is fixed to one of the ends of the profile on the wing 9 simply by a knot operated at the end of the halyard.

It travels in this cavity 10 forming a chute to exit at the other end by passing over the edge 3 and being inserted between the edge and the shoulder 5a of the wing 5 of the profile as shown in the figure. 8a. Then it suffices to pull on this halyard so that the edge 3 is unhooked as indicated in FIG. 8b in the manner in which the car windshields were previously put in place.

Thus according to the invention the installation of a false ceiling or a false wall is easily carried out using suitable spatulas.

The use of a halyard previously housed inside the profiles makes it possible to unhook false ceilings and false walls very easily, making interventions for routine maintenance or repairs. In addition, these profiles covered by the plastic sheet are made practically invisible, making the butts of the strips particularly aesthetic, thus avoiding the use of subterfuges such as the coloring of the profiles to confuse them with the plastic sheet.

The profiles according to the invention respond well to the goals set.
