Description

Domaine de l'inventionField of the invention

La présente invention concerne de façon générale les barres de seuil et autres éléments de bordure de revêtements de sol ou de mur.The present invention generally relates to threshold bars and other border elements of floor or wall coverings.

Exposé de l'art antérieurPresentation of the prior art

Les barres de seuil sont des éléments fixés au sol de locaux d'habitation, de bureaux ou industriels, au niveau de jonctions de deux revêtements de sol différents ou de niveaux différents. Une barre de seuil présente un intérêt à la fois fonctionnel et esthétique. Elle assure une protection des bords de revêtements de sol adjacents et masque leurs irrégularités tout en constituant une ligne de séparation nette et droite.Threshold bars are floor-standing elements of residential, office or industrial premises at junctions of two different floor coverings or levels. A threshold bar is both functional and aesthetic. It protects the edges of adjacent floor coverings and masks their irregularities while constituting a clean and straight line of separation.

D'autres éléments de bordure constituant des arrêts de bordure sont utilisés entre la limite d'un revêtement de sol et un mur également pour des raisons fonctionnelles et/ou esthétiques. Par exemple, quand le revêtement de sol est un parquet, il est souhaitable de laisser un jour entre la limite du parquet et le mur pour éviter des problèmes de dilatation. L'arrêt de bordure cache le jour et protège le bord de revêtement.Other border elements constituting edge stops are used between the boundary of a floor covering and a wall also for functional and / or aesthetic reasons. For example, when the flooring is a parquet, it is desirable to leave a day between the limit of the floor and the wall to avoid problems of expansion. The edge stop hides the day and protects the liner edge.

Des éléments de bordure sont également utilisés contre des parois, par exemple en plinthe ou en baguette de séparation de revêtements muraux.Border elements are also used against walls, for example skirting board or wall cover separating rod.

La figure 1 est une vue en coupe partielle en perspective d'une barre de seuil 2 connue, dite barre de seuil à glissière, en situation sur un sol 11 sur lequel sont déposés des revêtements de hauteur inégale, respectivement 12 et 13, par exemple une moquette et un carreau. La barre de seuil 2 a une partie supérieure apparente légèrement bombée et éventuellement elle-même peinte ou recouverte totalement ou partiellement d'un matériau pour lui donner tout aspect esthétique souhaité. La partie inférieure de la barre 2 comprend des nervures 21 et 22 en saillie définissant entre-elles et avec la partie inférieure 23 de la barre 2 une glissière longitudinale 24. Dans cette glissière peut être insérée la tête 31 d'un clou 32. Ce clou est destiné à être enfoncé dans un trou formé dans le sol 11 dans lequel a été préalablement introduit ou non une cheville 33.The figure 1 is a partial sectional view in perspective of a known threshold bar 2, called the sliding threshold bar, in a situation on a floor 11 on which are deposited unequal height coatings, respectively 12 and 13, for example a carpet and a tile. The threshold bar 2 has an apparent upper part slightly curved and possibly itself painted or covered totally or partially with a material to give it any desired aesthetic appearance. The lower part of the bar 2 comprises ribs 21 and 22 projecting defining between them and with the lower part 23 of the bar 2 a longitudinal slide 24. In this slide can be inserted the head 31 of a nail 32. This nail is intended to be driven into a hole formed in the ground 11 in which has previously been introduced or not an ankle 33.

La figure 2 est une vue en perspective d'un clou 3 illustrant une forme de tête de clou particulièrement bien adaptée à la glissière 24 de la barre 2. Cette tête 31 a la forme d'un demi-cylindre perpendiculaire à une tige 32 du clou et aplatie au côté opposé de cette tige. Ce demi-cylindre 31 forme un coulisseau apte à être glissé dans la glissière 24. Cette forme légèrement allongée des coulisseaux 31 permet d'éviter une rotation des têtes de clou et donc des tiges 32 de clou 3 dans un plan passant par l'axe longitudinal de la glissière. Ainsi, les tiges ne peuvent se coucher dans la glissière pendant la phase d'enfoncement. Dans l'exemple de la figure 3, le clou 3 est un "clou-cheville" en matière plastique muni d'ailettes 33 anti-arrachement, destiné à être enfoncé directement dans un trou ménagé dans le sol.The figure 2 is a perspective view of a nail 3 illustrating a form of nail head particularly well adapted to the slide 24 of the bar 2. This head 31 has the shape of a half-cylinder perpendicular to a rod 32 of the nail and flattened on the opposite side of this rod. This half-cylinder 31 forms a slider able to be slid into the slide 24. This slightly elongated shape of the sliders 31 makes it possible to avoid a rotation of the nail heads and thus of the nail rods 3 in a plane passing through the axis longitudinal of the slide. Thus, the rods can not lie in the slide during the driving phase. In the example of the figure 3 , the nail 3 is a "pin-peg" of plastic provided with fins 33 anti-tearing, intended to be driven directly into a hole in the ground.

Le système des figures 1 et 2 présente un avantage de simplicité de pose. En effet, il suffit de préparer dans le sol des trous en alignement sans qu'il soit nécessaire qu'ils aient entre eux des espacements rigoureux. Un nombre de clous 3 correspondant au nombre de trous est placé dans la glissière, après quoi les clous sont mis en place par glissement en face des trous correspondants puis la barre est enfoncée, en entraînant les clous. Cet enfoncement peut se faire simplement en marchant sur la barre.The system of Figures 1 and 2 has the advantage of simplicity of installation. Indeed, it is sufficient to prepare holes in alignment in the ground without it being necessary for them to have rigorous spacings between them. A number of nails 3 corresponding to the number of holes is placed in the slide, after which the nails are set up by sliding in front of the corresponding holes and then the bar is pressed, driving the nails. This depression can be done simply by walking on the bar.

Dans l'exemple des figures 1 et 2, la partie inférieure 23 de la glissière a de préférence la forme d'un V définissant une arrête d'appui 25 (figure 1) venant appuyer sensiblement au centre de la face plane supérieure de la tête 31 du clou 3. En outre, l'espace entre les lèvres en regard des nervures 21 et 22 est supérieur au diamètre de la tige 32 du clou 3. Ainsi, une fois que le clou est mis en place, et jusqu'à son enfoncement complet, la barre de seuil peut tourner légèrement autour des têtes de clou, l'axe de rotation correspondant à l'arrête d'appui 25. Ceci permet un positionnement à une fixation pour différentes hauteurs de décalage entre les revêtements 12 et 13. Comme cela est représenté en figure 1, les parois internes, vers leurs extrémités, des nervures 21 et 22 ont une forme complémentaire de l'arrondi du coulisseau 31. L'angle du V définissant l'arrête d'appui 25 est de préférence choisi pour que, quand la barre de seuil est dans une position d'inclinaison extrême, on ait simultanément un appui de la tige du clou contre l'une des lèvres des nervures 21, 22 et de la moitié supérieure de la tête de clou contre l'un des flans du V.In the example of Figures 1 and 2 , the lower part 23 of the slideway is preferably in the form of a V defining a support stop 25 ( figure 1 ) coming substantially to bear in the center of the upper flat face of the head 31 of the nail 3. In addition, the space between the lips opposite the ribs 21 and 22 is greater than the diameter of the rod 32 of the nail 3. Thus, a once the nail is in place, and until it is fully seated, the threshold bar can turn slightly around the nail heads, the axis of rotation corresponding to the support stop 25. a fixation for different shift heights between the coatings 12 and 13. As shown in FIG. figure 1 , the inner walls, towards their ends, ribs 21 and 22 have a shape complementary to the rounding of the slider 31. The angle of the V defining the bearing stop 25 is preferably chosen so that when the bar of threshold is in a position of extreme inclination, it is simultaneously a support of the nail rod against one of the lips of the ribs 21, 22 and the upper half of the nail head against one of the blanks V.

Une barre de seuil telle qu'illustrée par la figure 1 est décrite dans le brevet Européen 0 588 734 de la demanderesse.A threshold bar as illustrated by the figure 1 is described in the European patent 0 588 734 of the plaintiff.

D'autres barres de seuil à glissière sont connues qui définissent, dans leur face inférieure, une glissière adaptée à une tête de clou-vis ou de clou-cheville. Par exemple, les têtes de clou pourront avoir toute forme cylindrique souhaitée, par exemple être des cylindres à section circulaire. De même, dans un mode de réalisation simple, les tiges des clous peuvent être des tiges filetées.Other sliding threshold bars are known which define, in their lower face, a slide adapted to a nail-screw or nail-pin head. For example, the nail heads may have any desired cylindrical shape, for example circular cylinders. Similarly, in a simple embodiment, the rods of the nails may be threaded rods.

On pourra également envisager une structure inverse de celle de la figure 1 dans laquelle le fond 23 de la glissière est sensiblement plan et où c'est la tête 31 du clou qui est en forme de V convexe, l'arrête de ce V définissant un axe de rotation.We can also consider a structure opposite to that of the figure 1 wherein the bottom 23 of the slide is substantially planar and where it is the head 31 of the nail which is V-shaped convex, the stop of this V defining an axis of rotation.

Un perçage du sol ou du mur sur lequel doit être fixé l'élément de bordure n'est pas toujours possible ou souhaité. On utilise alors des éléments de bordure à coller sur la surface du revêtement.Drilling of the floor or wall on which the edge element is to be fixed is not always possible or desired. Border elements to be bonded to the surface of the coating are then used.

La figure 3 est une vue en perspective partielle d'une autre barre de seuil connue, dite barre de seuil collée. La barre de seuil 4 est, comme pour la barre de seuil 2 de la figure 1, destinée à masquer la ligne de séparation entre deux revêtements 13 et 12 (par exemple de hauteur inégale). L'aspect externe de la barre de seuil 4 est similaire à celui de la barre de seuil 2 et comporte donc une partie supérieure apparente légèrement bombée et éventuellement elle-même peinte ou recouverte d'un matériau pour lui donner tout aspect esthétique souhaité. La fixation de la barre de seuil 4 s'effectue par collage. Pour cela, deux cordons 41 et 42 de colle sont prédisposés en face inférieure de la barre 4 à proximité de ses bords longitudinaux. Avant pose, ces cordons sont généralement protégés par une bande papier ou film pelable que l'utilisateur ôte pour appliquer la barre de seuil.The figure 3 is a partial perspective view of another known threshold bar, the so-called threshold threshold bar. The threshold bar 4 is, as for the threshold bar 2 of the figure 1 , intended to mask the line of separation between two coatings 13 and 12 (for example of unequal height). The external appearance of the threshold bar 4 is similar to that of the threshold bar 2 and therefore comprises an upper part slightly curved and possibly itself painted or covered with a material to give it any desired aesthetic appearance. The fixing of the threshold bar 4 is done by gluing. For this, two beads 41 and 42 of adhesive are predisposed on the lower face of the bar 4 near its longitudinal edges. Before laying, these cords are generally protected by a paper tape or peelable film that the user removes to apply the threshold bar.

Un inconvénient des cordons de colle est qu'ils engendrent une surépaisseur qui nuit à l'esthétique. De plus, avec le temps, et le passage, les cordons de colle ont tendance à fluer, ce qui engendre un décalage de la barre de seuil ou une rupture cohésive de l'adhésif.A disadvantage of the glue beads is that they generate an extra thickness that affects the aesthetics. In addition, over time, and passage, glue beads tend to flow, resulting in a shift of the threshold bar or a cohesive failure of the adhesive.

On connaît également des solutions consistant à appliquer un adhésif double face sous une barre de seuil pour sa fixation. Une telle solution n'est toutefois applicable qu'aux barres de seuil planes. En effet, une telle bande adhésive n'adhère pas si elle placée sous une barre de seuil de hauteur variable, par exemple bombée. Par conséquent, elle n'est pas utilisable pour des barres susceptibles de s'adapter à des revêtements de hauteur variable ou inégale.Solutions are also known consisting in applying a double-sided adhesive under a threshold bar for fixing it. Such a solution is, however, applicable only to plane threshold bars. Indeed, such an adhesive strip does not adhere if it is placed under a threshold bar of variable height, for example curved. Therefore, she is not usable for bars that can adapt to uneven or variable height coatings.

Il serait souhaitable de pouvoir coller une barre de seuil pouvant s'adapter à des revêtements de hauteurs variables ou inégales, le cas échéant en rattrapage de niveau, de façon simple et fiable.It would be desirable to be able to stick a threshold bar that can adapt to coatings variable heights or uneven, where appropriate in catch-up level, simply and reliably.

Le document WO 2008/003849 décrit un ensemble de finitions multifonctions pour revêtement de sol comportant un profil de renforcement et un profil de façade. Le profil de façade est séparable en plusieurs modules. Le profil de renforcement rigidifie le profil de façade une fois assemblé avec celui-ci. Les deux modules latéraux sont séparables du module central.The document WO 2008/003849 describes a set of multifunction finishes for floor covering comprising a reinforcing profile and a facade profile. The façade profile is separable into several modules. The reinforcement profile stiffens the facade profile once assembled with it. The two side modules are separable from the central module.

Description détailléedetailed description

De mêmes éléments ont été désignés par de mêmes références aux différentes figures qui ont été tracées sans respect d'échelle. Par souci de clarté, seuls les éléments utiles à la compréhension de l'invention ont été représentés et seront décrits. En particulier, la fabrication des profilés des éléments de bordure auxquels s'applique plus particulièrement la présente invention n'a pas été détaillée, l'invention étant compatible avec les profilés usuels. De plus, l'invention sera décrite par la suite en relation avec un exemple d'application aux barres de seuil mais les modes de réalisation qui vont être décrits s'appliquent plus généralement à tout élément de bordure, qu'il s'agisse d'éléments de bordure de revêtement de sol ou de mur. En outre, l'invention sera décrite en relation avec un exemple de barre de seuil bombée, mais elle s'applique plus généralement à toute barre de seuil ou élément de bordure, préférentiellement de hauteur variable.The same elements have been designated by the same references to the different figures that have been drawn without respect of scale. For the sake of clarity, only the elements useful for understanding the invention have been shown and will be described. In particular, the manufacture of the profiles of the edge elements to which the present invention is more particularly applied is not detailed, the invention being compatible with the usual profiles. In addition, the invention will be described later in connection with an example of application to the threshold bars, but the embodiments that will be described apply more generally to any edge element, whether border elements of flooring or wall. In addition, the invention will be described in connection with an example of curved threshold bar, but it applies more generally to any threshold bar or edge member, preferably of variable height.

On utilisera par la suite les termes d'orientation et de position "dessus", "dessous", "inférieur", supérieur" etc, en se référant arbitrairement à une barre de seuil en position d'utilisation sur un sol.The terms of orientation and position "above", "below", "lower", "upper" etc. will then be used, arbitrarily referring to a threshold bar in use position on a floor.

La figure 4 est une vue en perspective partielle d'un mode de réalisation d'une barre de seuil 5 à coller.The figure 4 is a partial perspective view of an embodiment of a threshold bar 5 to be bonded.

La figure 5 est une vue en situation d'une barre de seuil 5 du type de celle représentée en figure 4.The figure 5 is a situation view of a threshold bar 5 of the type represented by figure 4 .

La barre de seuil 5 est un profilé monobloc définissant, en section, une portion centrale 6 et deux ailes latérales 7 articulées à cette portion centrale. La portion centrale 6 a, dans cet exemple, une face supérieure apparente 61 légèrement bombée et éventuellement peinte, teinte, ou totalement ou partiellement recouverte d'un matériau pour lui donner tout aspect esthétique souhaité.The threshold bar 5 is a one-piece profile defining, in section, a central portion 6 and two lateral wings 7 hinged to this central portion. The central portion 6 has, in this example, an upper surface 61 slightly convex and optionally painted, dyed, or totally or partially covered with a material to give it any desired aesthetic appearance.

Les ailes 7 sont destinées à être repliées sous la portion centrale 6 en reposant par leurs faces inférieures 71 (en position repliée) sur les revêtements de sol ou de mur. Chaque aile 7 est adhésive par cette face inférieure 71. Par exemple, des cordons de colle non représentés sont rapportés sur ces faces de collage en étant temporairement protégés par un film. Selon un autre exemple, des bandes adhésives double-face 8 (figure 5) sont rapportées sur les faces inférieures des ailes 7. Une bande de protection, par exemple un papier ou film pelable non représenté, est conservée avant pose de façon à protéger l'adhésif 8 avant fixation de la barre de seuil.The wings 7 are intended to be folded under the central portion 6 by resting by their lower faces 71 (in folded position) on the floor or wall coverings. Each wing 7 is adhesive by this lower face 71. For example, unrepresented adhesive cords are attached to these bonding faces by being temporarily protected by a film. In another example, double-sided adhesive tapes 8 ( figure 5 ) are reported on the lower faces of the wings 7. A protective strip, for example a paper or peelable film not shown, is retained before laying so as to protect the adhesive 8 before fixing the threshold bar.

Une portion de liaison 65 formant charnière relie chaque aile 7 à la portion centrale 6. De préférence, cette portion de liaison 65 forme un V dirigé vers l'intérieur, c'est-à-dire vers la portion centrale quand les ailes sont repliées. En pratique, l'épaisseur de la portion de liaison 65 est inférieure à celles de la portion centrale et des ailes, l'épaisseur des ailes étant préférentiellement inférieure à celle de la portion centrale.A hinge connecting portion 65 connects each flange 7 to the central portion 6. Preferably, this connecting portion 65 forms a V directed inwards, that is to say towards the central portion when the wings are folded . In practice, the thickness of the connecting portion 65 is less than that of the central portion and the wings, the thickness of the wings being preferably less than that of the central portion.

La barre de seuil 5 est monobloc et en matière plastique ou autre matière déformable, par exemple en PVC et est, de préférence, obtenue par extrusion. La matière constitutive de la barre de seuil monobloc pourra également être composite, par exemple un plastique chargé par des éléments ponctuels (grains) d'une autre nature (par exemple, du sable, du métal, etc.). Selon une autre variante, la barre de seuil est métallique.The threshold bar 5 is monobloc and plastic or other deformable material, for example PVC and is preferably obtained by extrusion. The material constituting the one-piece threshold bar may also be composite, for example a plastic loaded with point elements (grains) of another nature (for example, sand, metal, etc.). According to another variant, the threshold bar is metallic.

La pose de la barre de seuil 5 est particulièrement simple, l'utilisateur ôte les bandes de protection des deux côtés de la barre et applique celle-ci au sol. La forme donnée aux portions de liaison 65 leur confère un effet ressort, qui bien que léger est suffisant pour, à l'aide de l'adhésif 8, plaquer les ailes 7 au sol. Cet effet est amélioré si, lors de la pose, l'utilisateur retire progressivement les bandes de protection longitudinalement au fur et à mesure de la pose. Le cas échéant, l'utilisateur pourra coller d'abord l'un des deux côtés et le maroufler, puis coller le second comme décrit ci-dessus.The installation of the threshold bar 5 is particularly simple, the user removes the protective strips on both sides of the bar and applies it to the ground. The shape given to the connecting portions 65 gives them a spring effect, which although light is sufficient for, using the adhesive 8, to press the wings 7 to the ground. This effect is improved if, during installation, the user gradually withdraws the protection strips longitudinally as and when laying. If necessary, the user can first glue one of the two sides and rub it, then glue the second as described above.

Une fois la barre de seuil 5 collée, une pression appliquée sur celle-ci écrase la charnière et supprime toute surépaisseur, l'épaisseur des ailes étant absorbée dans l'espace interne défini par la forme bombée de la portion centrale. La portion centrale 6 repose alors par ses bords sur le sol.Once the threshold bar 5 is glued, a pressure applied on it crushes the hinge and eliminates any extra thickness, the thickness of the wings being absorbed in the internal space defined by the curved shape of the central portion. The central portion 6 then rests by its edges on the ground.

Dans l'exemple de la figure 5, on suppose un besoin de rattrapage de niveau entre deux revêtements 12 et 13 posés sur un sol 11. Les ailes 7g (gauche dans l'orientation de la figure) et 7d (droite dans l'orientation de la figure) reposent par leurs faces adhésives sur les revêtements 12 et 13 et assurent un collage de la barre de seuil 5 sans surépaisseur.In the example of the figure 5 , it is assumed a need for level catch between two coatings 12 and 13 placed on a floor 11. The wings 7g (left in the orientation of the figure) and 7d (right in the orientation of the figure) rest by their faces adhesives on the coatings 12 and 13 and ensure a bonding of the threshold bar 5 without excess thickness.

Dans les exemples représentés aux figures, la barre de seuil 5 est équipée en face interne, de nervures 21 et 22 définissant une glissière 24 autorisant un montage à l'aide de clou-vis ou de clou-cheville (3, figure 2). La barre de seuil est ainsi mixte, à coller et à glissière. On simplifie ainsi les gammes de distribution des barres de seuil ou éléments de bordure analogue. L'utilisateur peut au choix, fixer la barre par l'intermédiaire de sa glissière, la coller, ou les deux. La forme et position de la glissière peut varier en fonction de l'application.In the examples shown in the figures, the threshold bar 5 is equipped on the internal face with ribs 21 and 22 defining a slideway 24 allowing mounting by means of nail-bolts or nail-pegs (3, figure 2 ). The threshold bar is thus mixed, glue and slide. This simplifies the distribution ranges of the threshold bars or similar border elements. The user can choose, fix the bar through its slide, paste, or both. The shape and position of the slide can vary depending on the application.

La figure 6 illustre un autre exemple de mise en situation dans lequel une barre de seuil 5' est collée en bordure d'un revêtement 12 de sol 11 le long d'un mur 15. La barre 5' est d'abord collée par une de ses ailes 7d contre le mur 15 en ouvrant le pli de la portion de liaison. Puis, elle est rabattue sur le revêtement 12 où sa bande 7g assure le collage.The figure 6 illustrates another example of a scenario in which a threshold bar 5 'is glued to the edge of a floor covering 12 along a wall 15. The bar 5' is first glued by one of its wings 7d against the wall 15 by opening the fold of the connecting portion. Then, it is folded over the coating 12 where its band 7g ensures the bonding.

La figure 6 illustre une variante dans laquelle la barre de seuil est dépourvue de glissière en face inférieure de sa portion centrale.The figure 6 illustrates a variant in which the threshold bar has no slide on the underside of its central portion.

Un avantage des ailes de collage est qu'elles autorisent une épaisseur relativement importante d'adhésif à partir du moment où elles sont en section légèrement décalée du bord de la barre. Aucune surépaisseur ne subsiste alors après collage.An advantage of gluing wings is that they allow a relatively large thickness of adhesive from the moment they are slightly offset section of the edge of the bar. No extra thickness then remains after bonding.

Divers modes de réalisation ont été décrits, diverses variantes et modifications apparaitront à l'homme de l'art. En particulier, le choix des matériaux constitutifs de l'élément de bordure monobloc est à la portée de l'homme du métier à partir des indications fonctionnelles données ci-dessus et de l'application. De même, les dimensions (largeur des ailes, de la portion centrale, des portions de liaison) pourront être adaptées en fonction des largeurs des éléments de bordure.Various embodiments have been described, various variations and modifications will occur to those skilled in the art. In particular, the choice of materials constituting the monoblock edging element is within the abilities of those skilled in the art from the functional indications given above and the application. Similarly, the dimensions (width of the wings, the central portion, connecting portions) may be adapted according to the widths of the edge elements.
