Description

DOMAINE TECHNIQUETECHNICAL AREA

La présente invention concerne le secteur technique des revêtements de sols et murs à l'aide de matériaux en polychlorure de vinyle ou similaires et, plus particulièrement, un dispositif pour la pose de revêtement de sols et murs pour angles sortants.The present invention relates to the technical sector of floor and wall coverings using polyvinyl chloride materials or the like and, more particularly, a device for laying floor and wall covering for outward angles.

ART ANTERIEURPRIOR ART

Dans le domaine des revêtements de sol, il est bien connu différents procédés pour la pose des revêtements de sols et murs dans les parties d'angles sortants ; toutefois, ces procédés de pose présentent certains problèmes et inconvénients.In the field of floor coverings, it is well known various methods for laying floor and wall coverings in the outgoing corner portions; however, these laying methods present certain problems and disadvantages.

En référence aux figures 1 à 3, un premier procédé de pose usuellement exploité met en oeuvre les phases suivantes. On dispose le long de la ligne de jointement, entre le sol (1C) et les murs (1A,1B), un berceau (1) profilé en quart de cercle qui est fixé par collage, ou autre, par ses parties longitudinales d'extrémité, sur les faces en regard des parois de sols (1C) et de murs (1A,1B). Ensuite, le revêtement (R) du sol est présenté dans la partie d'angle en la faisant remonter pour venir contre les parois verticales (1A,1B) correspondantes du mur. Cela nécessite préalablement d'effectuer une opération de coupe du revêtement (R) selon une de coupe en V (2) dont la pointe du V correspond au point inférieur de l'angle entre les deux murs (1A,1B). Une pièce rapportée (3) en forme de V est alors rapportée au niveau de l'angle sortant et soudée au revêtement de sol (R) au niveau de la découpe en V (2). La soudure de la pièce rapportée (3) s'effectue en deux fois ce qui grève le temps de pose. Cette soudure à chaud, avec la dépose d'un cordon de soudure (4), part du point sortant inférieur et s'effectue le long des deux lignes obliques du V. La formation de l'angle (1D) dans les deux plans successifs verticaux (1A,1B) peut entraîner un effet de peau de tambour et un risque de déchirement si elle n'est pas bien réalisée.With reference to Figures 1 to 3 a first laying method usually used implements the following phases. Along the joint line, between the floor (1C) and the walls (1A, 1B), is a quarter-circle cradle (1) which is fixed by gluing, or otherwise, by its longitudinal parts. end, on the facing faces of the walls of floors (1C) and walls (1A, 1B). Then, the coating (R) of the soil is presented in the corner portion by raising it to come against the corresponding vertical walls (1A, 1B) of the wall. This requires prior to performing a cutting operation of the coating (R) in a V-section (2) whose tip of the V corresponds to the lower point of the angle between the two walls (1A, 1B). A V-shaped insert (3) is then attached at the outgoing angle and welded to the floor covering (R) at the V-cut (2). The solder of the insert (3) is performed in two times which strike the exposure time. This hot welding, with the removal of a bead of welding (4), part of the lower outgoing point and is carried out along the two oblique lines of V. The formation of the angle (1D) in the two successive vertical planes (1A, 1B) can cause a skin effect of drum and a risk of tearing if not done well.

Une des difficultés rencontrées reste le contrôle de la qualité de soudure qui ne peut se faire qu'au plan visuel. En pratique, on a constaté qu'il suffit qu'il y ait une infime amorce de rupture pour que l'étanchéité ne soit pas réalisée.One of the difficulties encountered is the control of the weld quality which can only be done visually. In practice, it has been found that it is sufficient that there is a small incipient break so that the seal is not achieved.

Un autre problème réside dans le fait que l'opération de soudure dans les angles, à la roulette ou à la buse, peut entraîner une détérioration du revêtement (R) dans l'angle telle que, par exemple, des brûlures du revêtement (R) avec l'apparition de déformations géométriques, renflements ou autres, avec un aspect visuel peu net.Another problem lies in the fact that the welding operation in the corners, at the wheel or at the nozzle, can cause a deterioration of the coating (R) in the angle such as, for example, burns of the coating (R ) with the appearance of geometric deformations, bulges or others, with a visual appearance not very clear.

Par ailleurs, ce type d'angle sortant présente des arêtes vives qui supportent mal les chocs avec les appareils de nettoyage provoquant régulièrement la déchirure du revêtement, et in fine, une perte d'étanchéité.Moreover, this type of outgoing angle has sharp edges that poorly withstand shocks with cleaning devices regularly causing tearing of the coating, and ultimately a loss of tightness.

De plus, sur les sols hétérogènes avec grille de verre, il est nécessaire de réaliser un grugeage en envers du revêtement de la pièce rapportée (3) en forme de V afin d'épouser l'arête de l'ange sortant. Outre le fait que cette étape grève le temps de pose, elle peut conduire à une casse de la grille au moment du pliage de la pièce rapportée (3).In addition, on heterogeneous soils with a glass grid, it is necessary to make a notch on the back of the coating of the V-shaped insert (3) in order to fit the edge of the outgoing angel. In addition to the fact that this step strikes the exposure time, it can lead to a breakage of the gate at the time of folding of the insert (3).

En référence aux figures 4 et 5, une autre solution de remontée en plinthe avec un angle sortant consiste à réaliser des bandes pliées à 90° revenant sur le sol (1C) sur une largeur d'environ 10 cm et à souder à plat cette bande au sol. Pour les angles sortants, une coque (5) est préalablement réalisée à partir d'une bande de revêtement de sol par pliage puis ladite coque (5) est étanchée en envers avec une résine adaptée. Ladite coque (5) est alors soudée avec le sol et les deux bandes partant de part et d'autre de l'angle sortant.With reference to Figures 4 and 5 , another solution of skirting with an outgoing angle is to make strips bent at 90 ° returning to the ground (1C) over a width of about 10 cm and solder flat this strip to the ground. For outward angles, a shell (5) is previously made from a strip of floor covering by folding and then said shell (5) is sealed upside down with a suitable resin. Said shell (5) is then welded with the ground and the two strips starting on either side of the outgoing angle.

Ce type de pose au niveau des angles sortants présente l'inconvénient de nécessiter un grand nombre de soudures grevant le temps de pose. Par ailleurs, il nécessite la réalisation préalable d'une coque (5), cette dernière étant généralement réalisée sur le chantier, grevant également le temps de pose. De plus, ce type d'angle sortant présente des arêtes vives qui supportent mal les chocs avec les appareils de nettoyage provoquant régulièrement la déchirure du revêtement et une perte d'étanchéité.This type of laying at the outgoing angles has the disadvantage of requiring a large number of welds on the exposure time. Furthermore, it requires the prior implementation of a shell (5), the latter is generally performed on the site, also affecting the exposure time. In addition, this type of outgoing angle has sharp edges that poorly withstand shocks with cleaning devices regularly causing the tearing of the coating and a loss of tightness.

EP 2 527 562 A1 décrit un dispositif pour la pose de revêtement de sols et murs pour angles sortants, consistant en une première partie centrale rigide, et une seconde partie périphérique souple, et la seconde partie périphérique souple s'étend depuis toute la périphérie de la partie centrale, ladite partie périphérique étant destinée à venir en appui sur la partie sol et sur la partie mur disposées en regard dudit dispositif. EP 2 527 562 A1 discloses a device for laying floor and wall coverings for outward angles, consisting of a first rigid central portion, and a second flexible peripheral portion, and the second flexible peripheral portion extends from the entire periphery of the central portion, said peripheral portion being intended to bear against the ground portion and the wall portion disposed opposite said device.

EXPOSE DE L'INVENTIONSUMMARY OF THE INVENTION

L'un des buts de l'invention est donc de remédier à tous ces inconvénients en proposant un dispositif pour la pose de revêtement de sols et murs pour angles sortants de conception simple et peu onéreuse, facile à utiliser par des opérateurs et agents de pose n'ayant pas une expertise spécifique, facile à poser, sans utilisation d'outils nécessaires à une transformation du dispositif d'un état à un autre, et aussi en s'affranchissant des imperfections inhérentes à l'état des parois de murs et aussi des variations d'angulation des deux parois consécutives d'un mur réceptionnant le dispositif permettant la pose du revêtement de sols et murs en angle sortant.One of the aims of the invention is therefore to remedy all these drawbacks by proposing a device for laying flooring and walls for outbound corners of simple design and inexpensive, easy to use by operators and laying agents having no specific expertise, easy to install, without the use of tools necessary for a transformation of the device from one state to another, and also by overcoming the imperfections inherent in the state of the wall walls and also variations of angulation of the two consecutive walls of a wall receiving the device for laying the flooring and walls outward angle.

A cet effet et conformément à l'invention, il est proposé un dispositif pour la pose de revêtement de sols et murs pour angles sortants, remarquable en ce qu'il comporte deux parties, une première partie dite centrale rigide présentant une forme de quart de tronc de cône et une seconde partie dite périphérique souple présentant une forme sensiblement triangulaire qui s'étend depuis toute la périphérie de la partie centrale (6), ladite partie périphérique venant en appui sur la partie sol et sur la partie mur disposées en regard dudit dispositif.For this purpose and in accordance with the invention, there is provided a device for the laying of flooring and walls for outward angles, remarkable in that it comprises two parts, a first so-called rigid central portion having a quarter-form of truncated cone and a second so-called flexible peripheral portion having a substantially triangular shape extending from the entire periphery of the central portion (6), said peripheral portion bearing against the ground portion and the wall portion disposed facing said device.

On comprend bien que la pose du dispositif est rapide et aisée, contrairement aux dispositifs de l'art antérieur, et que les bords de la partie périphérique, de par sa souplesse et sa flexibilité, s'appliquent parfaitement contre les parois de murs et de sols quelques soient les défauts de ces dernières.It is understood that the installation of the device is fast and easy, unlike the devices of the prior art, and that the edges of the peripheral part, by its flexibility and flexibility, apply perfectly against the wall and floor walls whatever the defects of the latter.

Selon une variante d'exécution, la partie centrale présente une forme de quart de tronc de cône dont la base est évasée vers l'extérieur.According to an alternative embodiment, the central portion has a quarter-truncated cone shape whose base is flared outwardly.

De préférence, les deux sommets de la base de la partie périphérique (6) sont arrondis.Preferably, the two vertices of the base of the peripheral portion (6) are rounded.

Par ailleurs, la partie périphérique consiste dans une zone de matière souple liée avec la matière synthétique rigide dans laquelle est obtenue la partie centrale.Furthermore, the peripheral portion consists of a zone of flexible material bonded with the rigid synthetic material in which the central portion is obtained.

De préférence, la partie centrale et la partie périphérique sont obtenues dans du polychlorure de vinyle.Preferably, the central portion and the peripheral portion are obtained in polyvinyl chloride.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

Par souci de clarté, dans la suite de la description, les mêmes éléments ont été désignés par les mêmes références aux différentes figures. De plus, les diverses vues ne sont pas nécessairement tracées à l'échelle.For the sake of clarity, in the remainder of the description, the same elements have been designated by the same references in the various figures. In addition, the various views are not necessarily drawn to scale.

En référence à la figure 6, le dispositif pour la pose de revêtement de sols et murs pour angles sortants suivant l'invention comporte deux parties, une première partie dite centrale (6) rigide présentant une forme sensiblement de quart de tronc de cône creux et une seconde partie dite périphérique (7) souple présentant une forme sensiblement triangulaire qui s'étend depuis le long des deux bords verticaux de la partie centrale (6), ladite partie périphérique (7) venant en appui sur la partie sol et sur la partie mur disposées en regard dudit dispositif comme il sera détaillé un peu plus loin.With reference to the figure 6 , the device for laying flooring and walls for outward angles according to the invention comprises two parts, a first so-called central portion (6) rigid having a substantially quarter-hollow truncated cone shape and a second so-called peripheral portion ( 7) flexible having a substantially triangular shape extending from the two vertical edges of the central portion (6), said peripheral portion (7) bearing on the ground portion and the wall portion disposed opposite said device as it will be detailed a little further.

Ladite partie centrale (6) consiste dans une pièce rigide et creuse présentant une forme de quart de tronc de cône. Ladite partie périphérique (7) consiste dans deux pièces souples, c'est-à-dire flexibles, présentant une forme sensiblement triangulaire dont les deux sommets de la base sont arrondis et dont le sommet opposé à la base s'étend à proximité de l'extrémité supérieure de la partie centrale (6), l'extrémité supérieure de la partie centrale (6) correspondant à la petite base du tronc de cône. Par ailleurs, le quart de tronc de cône de la partie centrale (6) est de préférence évasé vers l'extérieur, c'est-à-dire que la paroi de la partie centrale (6) est concave avec la concavité orientée vers l'extérieur. De manière similaire, la partie périphérique (7) flexible est de préférence concave avec la concavité orientée vers l'extérieur, c'est-à-dire orientée du côté opposé aux murs lorsque le dispositif est mis en place dans un angle.Said central portion (6) consists of a rigid and hollow piece having a quarter-truncated cone shape. Said peripheral portion (7) consists of two flexible pieces, that is to say flexible, having a substantially triangular shape whose two peaks of the base are rounded and whose apex opposite the base extends near the upper end of the central part (6), the upper end of the central portion (6) corresponding to the small base of the truncated cone. Furthermore, the quarter-truncated cone of the central portion (6) is preferably outwardly flared, that is to say that the wall of the central portion (6) is concave with the concavity oriented towards the outside. 'outside. Similarly, the flexible peripheral portion (7) is preferably concave with the concavity facing outward, i.e., facing away from the walls when the device is set up at an angle.

Par ailleurs, ladite partie périphérique (7) consiste dans une zone de matière souple liée avec la matière synthétique rigide dans laquelle est obtenue la partie centrale (6) rigide. La matière synthétique rigide dans laquelle est obtenue la partie centrale (6) consiste par exemple dans du polychlorure de vinyle (PVC) rigide bien connu de l'homme du métier et, la partie périphérique (7) est obtenue par l'introduction d'un ou plusieurs plastifiants, bien connus de l'homme du métier, dans du polychlorure de vinyle (PVC) afin d'obtenir du polychlorure de vinyle (PVC) souple. Par ailleurs, d'autres polymères avec ces caractéristiques de rigidité ou de souplesse peuvent remplir les mêmes fonctions pour la partie centrale (6) ou la partie périphérique (7).Furthermore, said peripheral portion (7) consists of an area of flexible material bonded with the rigid synthetic material in which is obtained the rigid central portion (6). The rigid synthetic material in which the central portion (6) is obtained consists for example of rigid polyvinyl chloride (PVC) well known to those skilled in the art and the peripheral part (7) is obtained by the introduction of one or more plasticizers, well known to those skilled in the art, in polyvinyl chloride (PVC) to obtain flexible polyvinyl chloride (PVC). On the other hand, other polymers with these rigidity or flexibility characteristics can fulfill the same functions for the central part (6) or the peripheral part (7).

Selon l'invention, la partie périphérique souple (7) est obtenue par surmoulage de la partie centrale rigide (6). La nature chimique de la partie centrale (6) et la partie périphérique (7) étant obtenue dans la même matière, ou dans une matière différente.According to the invention, the flexible peripheral portion (7) is obtained by overmolding the rigid central portion (6). The chemical nature of the central portion (6) and the peripheral portion (7) being obtained in the same material, or in a different material.

Le dispositif pour la pose de revêtements de sols et de murs pour angles sortants est référencé dans son ensemble par (D). Il est destiné à être positionné dans une partie d'angle entre paroi de mur (M) et sol (S). Des bordures (1), connues en soi, obtenues par moulage, par exemple, sont disposées dans les parties d'angle entre le sol entre la ou les paroi(s) dans les zones de longueur de la pièce à recouvrir dudit revêtement (R).The device for laying floor and wall coverings for outward angles is referenced as a whole by (D). It is intended to be positioned in a corner portion between wall wall (M) and floor (S). Borders (1), known per se, obtained by molding, for example, are arranged in the corner portions between the floor between the wall (s) in the length zones of the part to be covered with said coating (R ).

Accessoirement, le bord inférieur de la partie centrale (6) rigide pourra présenter un bourrelet, le bord inférieur de la plinthe prenant appui au fond du creux formé par le bourrelet, assurant ainsi une parfaite étanchéité.Incidentally, the lower edge of the rigid central portion (6) may have a bead, the lower edge of the plinth bearing against the bottom of the hollow formed by the bead, thus ensuring a perfect seal.

On expliquera maintenant le fonctionnement du dispositif pour la pose de revêtement de sols et murs pour angles sortants suivant l'invention en référence aux figures 9 à 11.We will now explain the operation of the device for laying flooring and walls for outgoing corners according to the invention with reference to Figures 9 to 11 .

Des bordures (1), connues en soi, obtenues par moulage, par exemple, sont préalablement disposées dans les parties d'angle entre le sol et la ou les paroi(s) dans les zones de longueur de la pièce à recouvrir dudit revêtement. Puis le dispositif est positionné au droit de l'angle sortant de telle sorte que le bord de la base de la partie périphérique (7) prenne appui sur le sol et les parties de mur (1A,1B), le sommet de la partie centrale (6) rigide prenne appui sur l'arrête (M) de la paroi de mur et que la partie inférieure de la partie centrale (6) prenne appui sur le sol (1C). L'opérateur peut alors poser le revêtement de sol en recouvrant les bordures et le dispositif suivant l'invention.Borders (1), known per se, obtained by molding, for example, are previously arranged in the corner portions between the floor and the wall (s) in the length areas of the part to be covered with said coating. Then the device is positioned at the angle of the outgoing angle so that the edge of the base of the peripheral portion (7) bears on the floor and the wall portions (1A, 1B), the top of the central portion. (6) rigid bears on the edge (M) of the wall wall and the lower part of the central portion (6) bears on the ground (1C). The operator can then lay the floor covering covering the borders and the device according to the invention.

On observera que les avantages tels que la simplicité du dispositif et sa pose rapide et aisée ressortent bien de la description. On notera plus particulièrement que les bords de la partie périphérique (7), de par sa souplesse et sa flexibilité, s'appliquent parfaitement contre les parois de murs et de sols quelques soient les défauts de ces dernières. On notera également que le dispositif suivant l'invention permet une pose rapide quelle que soit la taille du dispositif sans nécessiter de gabarit ou d'outils de pose spécifiques. Par ailleurs, le soudage est effectué en une seule fois sans raccordement car s'effectuant au niveau de la partie inférieure de la partie centrale (6) rigide. De plus, outre le fait que l'étanchéité est assurée du fait que la soudure n'est pas réalisée au niveau du sol, la forme arrondie du dispositif ne procure pas d'effet peau de tambour et permet un entretien facile des sols avec des appareils industriels ou manuels.It will be observed that the advantages such as the simplicity of the device and its quick and easy installation stand out from the description. It will be noted more particularly that the edges of the peripheral portion (7), by its flexibility and flexibility, apply perfectly against the wall and floor walls, whatever the defects of the latter. Note also that the device according to the invention allows rapid installation regardless of the size of the device without the need for jig or specific installation tools. Furthermore, the welding is performed in one go without connection because being performed at the lower part of the central portion (6) rigid. Moreover, besides the fact that the watertightness is ensured by the fact Since the welding is not carried out at ground level, the rounded shape of the device does not provide a drum-skin effect and allows easy maintenance of the floors with industrial or manual appliances.

Selon une variante d'exécution du dispositif suivant l'invention, en référence aux figure 7 et 8, le dispositif comporte de la même manière que précédemment deux parties, une première partie dite centrale (6) rigide et une seconde partie dite périphérique (7) souple présentant une forme sensiblement triangulaire qui s'étend depuis le long des deux bords verticaux de la partie centrale (6), ladite partie périphérique (7) venant en appui sur la partie sol et sur la partie mur disposées en regard dudit dispositif comme il sera détaillé un peu plus loin.According to an alternative embodiment of the device according to the invention, with reference to figure 7 and 8 , the device comprises in the same manner as previously two parts, a first so-called central portion (6) rigid and a second said flexible peripheral portion (7) having a substantially triangular shape that extends from the two vertical edges of the central portion (6), said peripheral portion (7) bearing on the ground portion and on the wall portion disposed opposite said device as will be detailed a little further.

Dans cet exemple particulier de réalisation, en référence à la figure 8, la partie centrale (6) est obtenue dans un polymère, par exemple du polychlorure de vinyle (PVC), comportant plusieurs épaisseurs afin d'assurer la rigidité de ladite partie centrale et la partie périphérique (7) est également obtenue dans ce même polymère avec une épaisseur nettement inférieure à celle de la partie centrale (6) de telle manière que la partie périphérique (7) soit flexible.In this particular embodiment, with reference to the figure 8 , the central portion (6) is obtained in a polymer, for example polyvinyl chloride (PVC), having several thicknesses to ensure the rigidity of said central portion and the peripheral portion (7) is also obtained in the same polymer with a thickness substantially lower than that of the central portion (6) so that the peripheral portion (7) is flexible.

De la même manière que précédemment, ladite partie périphérique (7) pourra consister dans une zone de matière souple liée avec la matière synthétique rigide dans laquelle est obtenue la partie centrale (6) rigide. La matière synthétique rigide dans laquelle est obtenue la partie centrale (6) consiste par exemple dans du polychlorure de vinyle (PVC) rigide bien connu de l'homme du métier et, la partie périphérique (7) est obtenue par l'introduction d'un ou plusieurs plastifiants, bien connus de l'homme du métier, dans du polychlorure de vinyle (PVC) afin d'obtenir du polychlorure de vinyle (PVC) souple.In the same manner as above, said peripheral portion (7) may consist of a zone of flexible material bonded with the rigid synthetic material in which the rigid central portion (6) is obtained. The rigid synthetic material in which the central portion (6) is obtained consists for example of rigid polyvinyl chloride (PVC) well known to those skilled in the art and the peripheral part (7) is obtained by the introduction of one or more plasticizers, well known to those skilled in the art, in polyvinyl chloride (PVC) to obtain flexible polyvinyl chloride (PVC).

Selon l'invention, la partie périphérique (7) est obtenue par surmoulage de la partie centrale rigide (6), la nature chimique de la partie centrale (6) et la partie périphérique (7) étant obtenue dans la même matière, ou dans une matière différente, soit par la variation de l'épaisseur d'une matière souple appropriée conférant à la partie centrale (6) plus de rigidité que la partie périphérique (7).According to the invention, the peripheral part (7) is obtained by overmolding the rigid central portion (6), the chemical nature of the central portion (6) and the peripheral portion (7) being obtained in the same material, or in a different material, or by varying the thickness of the a suitable flexible material giving the central portion (6) more rigidity than the peripheral portion (7).
