Description

BARRE DE SEUIL A RATTRAPAGE DE NIVEAU LEVEL TAKE-UP THRESHOLD

La présente invention concerne une barre de seuil, c'est-à-dire un élément destiné à cacher un joint entre deux revêtements de sol ou à constituer une bordure nette entre un revêtement de sol et une paroi. La présente invention concerne plus particulièrement une barre de seuil adaptable à diverses hauteurs de revêtement et permettant de rattraper la différence de hauteur entre deux revêtements de sol.The present invention relates to a threshold bar, that is to say an element intended to hide a joint between two floor coverings or to constitute a clear border between a floor covering and a wall. The present invention relates more particularly to a threshold bar adaptable to various coating heights and making it possible to make up for the difference in height between two floor coverings.

La figure 1 représente une vue en coupe d'une barre de seuil classique de ce type, décrite dans la demande de brevet européen 0 321 634. Cette barre de seuil comporte un profilé socle 10 en forme de L comportant une partie horizontale fixée au sol 12 et une partie verticale 10-1 destinée à fixer un profilé de recouvrement 14. La partie verticale 10-1 du profilé socle est épaisse et comporte des taraudages 16 régulièrement espacés des- tinés à fixer le profilé de recouvrement 14 par vis.Figure 1 shows a sectional view of a conventional threshold bar of this type, described in European patent application 0 321 634. This threshold bar comprises a base profile L-shaped 10 having a horizontal part fixed to the ground 12 and a vertical part 10-1 intended to fix a covering profile 14. The vertical part 10-1 of the base profile is thick and comprises threads 16 regularly spaced intended to fix the covering profile 14 by screws.

Le profilé de recouvrement 14 comporte deux languettes verticales 14-1 qui viennent en appui de part et d'autre de la partie verticale 10-1 du profilé socle. Le profilé de recouvrement 14 comporte en outre deux ailes inclinées 14-2 et 14-3, s 'étendant vers le bas de part et d'autre de la partie supérieure des languettes 14-1. L'une des ailes inclinées 14-2 est destinée à venir en appui, comme cela est représenté, sur un revêtement de sol épais 18, tandis que l'autre aile inclinée 14-3 est destinée à venir en appui sur un revêtement de sol mince. Un inconvénient de cette barre de seuil est qu'elle est prévue pour rattraper une différence de niveau spécifique entre revêtements de sol. Une légère variation de la différence de niveau est permise par une certaine souplesse conférée aux ailes inclinées du profilé de recouvrement, permettant leur déformation. En effet, ces ailes sont raccordées à la partie centrale du profilé par des zones amincies 19. Mais cette solution est insuffisante pour permettre un rattrapage d'un grand éventail de différences de niveau. Le modèle d'utilité allemand 29 711 389 décrit un système complémentaire de celui représenté en figure 1, dans lequel, au lieu que deux languettes verticales du profilé de recouvrement viennent prendre appui de part et d'autre de la partie verticale du profilé socle, une languette verticale du profilé de recouvre- ment vient s'insérer dans une rainure d'un profilé socle. A nouveau, ce système ne permet de rattraper qu'une légère différence de niveau, sauf à tordre les ailes du profilé de recouvrement en profitant de l'existence de zones amincies.The cover profile 14 comprises two vertical tabs 14-1 which come into abutment on either side of the vertical part 10-1 of the base profile. The cover profile 14 further comprises two inclined wings 14-2 and 14-3, extending downward on either side of the upper part of the tongues 14-1. One of the inclined wings 14-2 is intended to come to bear, as shown, on a thick floor covering 18, while the other inclined wing 14-3 is intended to come to rest on a floor covering slim. A disadvantage of this threshold bar is that it is designed to make up for a specific difference in level between floor coverings. A slight variation in the level difference is allowed by a certain flexibility given to the inclined wings of the cover profile, allowing their deformation. Indeed, these wings are connected to the central part of the profile by thinned zones 19. But this solution is insufficient to allow a large range of level differences to be made up. The German utility model 29 711 389 describes a system complementary to that shown in FIG. 1, in which, instead of two vertical tabs of the cover profile coming to bear on either side of the vertical part of the base profile, a vertical tongue of the cover profile is inserted into a groove of a base profile. Again, this system only makes up for a slight difference in level, except to twist the wings of the cover profile while taking advantage of the existence of thinned zones.

Un objet de la présente invention est de prévoir une barre de seuil permettant un rattrapage d'un grand éventail de différences de niveau tout en assurant une résistance élevée aux efforts latéraux.An object of the present invention is to provide a threshold bar allowing a large range of level differences to be compensated for while ensuring high resistance to lateral forces.

Ces objets sont atteints grâce à une barre de seuil comportant un profilé socle à fixer au sol et un profilé de recouvrement à fixer par vis au profilé socle, dans laquelle le profilé de recouvrement comprend une languette longitudinale, et des trous de passage de vis le long d'un axe parallèle à la languette ; et le profilé socle comporte deux rainures longitudinales parallèles et juxtaposées, une première destinée à recevoir la languette et la deuxième destinée à recevoir des vis traversant les trous de passage du profilé de recouvrement. La languette est dimensionnée par rapport à la rainure destinée à la recevoir de façon à pouvoir pivoter autour d'un axe longitudinal . ~ These objects are achieved by means of a threshold bar comprising a base profile to be fixed to the ground and a cover profile to be fixed by screws to the base profile, in which the cover profile comprises a longitudinal tab, and screw passage holes the along an axis parallel to the tongue; and the base profile has two parallel and juxtaposed longitudinal grooves, a first intended to receive the tongue and the second intended to receive screws passing through the holes of passage of the covering profile. The tongue is dimensioned relative to the groove intended to receive it so as to be able to pivot around a longitudinal axis. ~

Selon un mode de réalisation de la présente invention, la languette se termine par une partie épaissie et en ce que la première rainure a une largeur sensiblement égale à la largeur de la partie épaissie de la languette.According to an embodiment of the present invention, the tongue ends in a thickened part and in that the first groove has a width substantially equal to the width of the thickened part of the tongue.

Selon un mode de réalisation de la présente invention, les parois de la deuxième rainure sont striées longitudinalement sensiblement au pas de filetage des vis de fixation du profilé de recouvrement .According to an embodiment of the present invention, the walls of the second groove are striated longitudinally substantially at the thread pitch of the fixing screws of the covering profile.

Selon un mode de réalisation de la présente invention, les rainures (31, 32) sont de même configuration, de manière que le profilé de recouvrement puisse être retourné. Selon un mode de réalisation de la présente invention, les parois des deux rainures sont striées longitudinalement sensiblement au pas de filetage des vis de fixation du profilé de recouvrement, et en ce que ladite languette est striée au même pas, la larguer maximale de la languette étant inférieure à la largeur minimale d'une rainure.According to an embodiment of the present invention, the grooves (31, 32) are of the same configuration, so that the cover profile can be turned over. According to an embodiment of the present invention, the walls of the two grooves are grooved longitudinally substantially at the thread pitch of the fixing screws of the covering profile, and in that said tongue is grooved at the same pitch, the maximum width of the tongue being less than the minimum width of a groove.

Selon un mode de réalisation de la présente invention, la languette s'étend continûment sur la longueur du profilé de recouvrement .According to an embodiment of the present invention, the tongue extends continuously over the length of the cover profile.

Ces objets, caractéristiques et avantages, ainsi que d'autres de la présente invention seront exposés en détail dans la description suivante de modes de réalisation particuliers faite à titre non-limitatif en relation avec les figures jointes parmi lesquelles : la figure 1, précédemment décrite, représente une barre de seuil classique ; la figure 2 représente un mode de réalisation de barre de seuil selon la présente invention ; et les figures 3A et 3B représentent un profilé de recouvrement réversible selon un deuxième mode de réalisation de la présente invention.These objects, characteristics and advantages, as well as others of the present invention will be explained in detail in the following description of particular embodiments given without limitation in relation to the attached figures, among which: FIG. 1, previously described , represents a conventional threshold bar; FIG. 2 represents an embodiment of threshold bar according to the present invention; and Figures 3A and 3B show a reversible cover profile according to a second embodiment of the present invention.

Une barre de seuil selon la présente invention permet de rattraper une large plage de différences de niveau grâce au fait que son profilé de recouvrement présente une certaine liberté de rotation autour d'un axe longitudinal tout en ayant une latitude de déplacement vertical.A threshold bar according to the present invention makes it possible to make up for a wide range of level differences thanks to the fact that its covering profile has a certain freedom of rotation around a longitudinal axis while having a latitude of vertical movement.

A la figure 2, une barre de seuil selon la présente invention comprend un profilé socle 20 comportant deux rainures verticales parallèles juxtaposées 21 et 22. L'une des rainures, 21, est destinée à recevoir une languette verticale 24 d'un profilé de recouvrement 25. L'autre rainure, 22, est destinée à recevoir des vis 27 de fixation du profilé de recouvrement 25 au socle 20. A cet effet, le profilé de recouvrement 25 comporte des trous 28 régulièrement espacés longitudinalement, en correspondance avec la rainure 22. Comme cela est représenté, pour améliorer la fiabilité de la fixation par vis, les parois de la rainure 22 sont striées longitudinalement sensiblement au pas de filetage des vis 27.In FIG. 2, a threshold bar according to the present invention comprises a base profile 20 comprising two grooves parallel vertical juxtaposed 21 and 22. One of the grooves, 21, is intended to receive a vertical tongue 24 of a cover profile 25. The other groove, 22, is intended to receive screws 27 for fixing the profile of covering 25 at the base 20. For this purpose, the covering profile 25 has holes 28 regularly spaced longitudinally, in correspondence with the groove 22. As shown, to improve the reliability of the fixing by screws, the walls of the groove 22 are striated longitudinally substantially at the thread pitch of the screws 27.

Selon un aspect important de ce mode de réalisation de l'invention, la partie inférieure de la languette 24 comporte une partie épaissie 29, par exemple cylindrique, de largeur sensiblement égale à la largeur de la rainure 21. Avec cette configuration, la languette 24, et donc le profilé de recouvrement 25, peuvent tourner de part et d'autre du centre de la partie épaissie 29 jusqu'à ce qu'une paroi de la languette 24 entre en contact avec un bord supérieur de la rainure 21. Cette liberté de rotation permet au profilé de recouvrement 25 de s'adapter à une plage de différences de niveau entre les revêtements de sol, cette plage étant d'autant plus importante que la position de la partie épaissie 29 dans la rainure 21 est haute.According to an important aspect of this embodiment of the invention, the lower part of the tongue 24 has a thickened part 29, for example cylindrical, of width substantially equal to the width of the groove 21. With this configuration, the tongue 24 , and therefore the cover profile 25, can rotate on either side of the center of the thickened part 29 until a wall of the tongue 24 comes into contact with an upper edge of the groove 21. This freedom of rotation allows the cover profile 25 to adapt to a range of level differences between the floor coverings, this range being all the greater the higher the position of the thickened part 29 in the groove 21.

Normalement, lorsqu'on serre les vis 27, les bords latéraux du profilé de recouvrement 25 viennent en contact avec leurs revêtements de sol respectifs et la languette 24 s'enfonce d'une quantité correspondante dans la rainure 21. Alors-, tout effort latéral exercé sur le profilé de recouvrement 25 est transmis de la languette 24 à l'une des parois de la rainure 21 par l'intermédiaire de la partie épaissie 29, ce qui soulage les vis 27 des efforts latéraux. En effet, les fixations par vis supportent mal les efforts latéraux dus, par exemple, à des coups de pieds dans la barre de seuil, à des passages de chariots ou à des déplacements de meubles. C'est pourquoi dans la barre de seuil classique de la figure 1, il n'y a pas de jeu entre les languettes 14- 1 et la partie verticale 10-1 du profilé socle, cette absence de jeu empêchant toute rotation du profilé de recouvrement. Pour obtenir une rigidité maximale de la languette 24, et donc optimiser son aptitude à transmettre les efforts latéraux, cette languette est de préférence continue et s ' étend sur toute la longueur de la barre de seuil. Malgré la liberté de rotation du profilé de recouvrement 25, une barre de seuil selon la présente invention ne permet pas de rattraper toutes les différences de niveau dans tous les cas. Pour élargir l'éventail de différences de niveau rattrapa- bles, on prévoit des profilés de recouvrement de formes différen- tes.Normally, when the screws 27 are tightened, the lateral edges of the covering profile 25 come into contact with their respective floor coverings and the tongue 24 is inserted by a corresponding amount into the groove 21. So, any lateral force exerted on the cover profile 25 is transmitted from the tongue 24 to one of the walls of the groove 21 via the thickened part 29, which relieves the screws 27 from the lateral forces. In fact, the screw fasteners do not withstand the lateral forces due, for example, to kicks in the threshold bar, to the passage of trolleys or to movement of furniture. This is why in the conventional threshold bar of FIG. 1, there is no play between the tongues 14-1 and the vertical part 10-1 of the base profile, this absence of play preventing any rotation of the profile from recovery. To obtain maximum rigidity of the tongue 24, and therefore optimize its ability to transmit lateral forces, this tongue is preferably continuous and extends over the entire length of the threshold bar. Despite the freedom of rotation of the covering profile 25, a threshold bar according to the present invention does not make it possible to make up for all the level differences in all cases. To widen the range of compensable level differences, cover profiles of different shapes are provided.

A titre d'exemple, la figure 2 représente un profilé de recouvrement 26 plat permettant de rattraper des différences de niveau entre des revêtements de sol ayant sensiblement la même épaisseur. Lorsque le profilé de recouvrement est asymétrique, il est intéressant de pouvoir le retourner, en insérant la languette dans l'une quelconque des rainures et les vis dans l'autre. Ceci permet de positionner le profilé de recouvrement indépendamment de la position initiale du socle 20. Alors, la rainure 21 aura la même configuration que la rainure 22 et sera de préférence striée .By way of example, FIG. 2 shows a flat cover profile 26 making it possible to make up for differences in level between floor coverings having substantially the same thickness. When the cover profile is asymmetrical, it is advantageous to be able to turn it over, by inserting the tongue in one of the grooves and the screws in the other. This makes it possible to position the covering profile independently of the initial position of the base 20. Then, the groove 21 will have the same configuration as the groove 22 and will preferably be striated.

Les figures 3A et 3B représentent un tel mode de réalisation pour deux hauteurs d'un revêtement de sol 18. Un profilé socle 30 comprend deux rainures verticales parallèles juxtaposées 31 et 32. Ces deux rainures sont striées longitudinalement. Dans le montage représenté, la rainure 32 reçoit une languette verticale 34 d'un profilé de recouvrement 35 comprenant deux ailes 35-1 et 35-2. La bordure de l'aile 35-1 prend appui sur le revêtement 18 et la bordure de l'aile 35-2 prend appui sur le sol. La languette 34 est striée. La plus grande largeur de la languette, après formation des stries, est plus petite que la largeur minimale définie par les parties en saillie des rainures. Ainsi, par exemple, si la plus petite largeur des rainures est de 1 ' ordre de 2 , 6 mm, la plus grande largeur de la languette sera de l'ordre de 2,4 mm. Ainsi, le profilé de recouvrement peut être inséré sensiblement verticalement dans une rainure et peut passer de la position représentée en figure 3A à la position inclinée représentée en figure 3B. On notera toutefois que la représentation de la figure 3B est très schématique. Chaque trou de vis 38 sera de préférence oblong pour que la vis puisse continuer à s'insérer verticalement dans la rainure sous-jacente et, une fois la vis engagée, la languette sera en butée par au moins deux points de ses côtés opposés avec la rainure correspondante, de façon à assurer la fonction de rigidité et l'aptitude à transmettre les efforts latéraux susmentionnés. Comme cela est représenté, le profilé de recouvrement présente de façon préférée une surépaisseur aux emplacements où sont formés les trous, éventuellement oblongs, d'insertion des vis.FIGS. 3A and 3B represent such an embodiment for two heights of a floor covering 18. A base section 30 comprises two parallel vertical grooves juxtaposed 31 and 32. These two grooves are striated longitudinally. In the assembly shown, the groove 32 receives a vertical tongue 34 of a cover profile 35 comprising two wings 35-1 and 35-2. The edge of the wing 35-1 is supported on the covering 18 and the edge of the wing 35-2 is supported on the ground. The tongue 34 is striated. The largest width of the tongue, after formation of the grooves, is smaller than the minimum width defined by the projecting parts of the grooves. Thus, for example, if the smallest width of the grooves is of the order of 2.6 mm, the largest width of the tongue will be of the order of 2.4 mm. Thus, the cover profile can be inserted substantially vertically in a groove and can pass from the position shown in Figure 3A to the inclined position shown in Figure 3B. Note however that the representation of Figure 3B is very schematic. Each screw hole 38 will preferably be oblong so that the screw can continue to be inserted vertically in the underlying groove and, once the screw engaged, the tongue will be in abutment by at least two points on its opposite sides with the corresponding groove, so as to ensure the rigidity function and the ability to transmit the aforementioned lateral forces. As shown, the cover profile preferably has an extra thickness at the locations where the holes, optionally oblong, of the screw insertion are formed.

La présente invention est susceptible de nombreuses variantes qui apparaîtront à l'homme de l'art. Notamment, le profilé de recouvrement pourra avoir diverses formes, par exemple les formes usuelles propres à satisfaire les fonctions usuelles de formation d'un joint entre des revêtements de hauteurs variables et/ou différentes, et de façon à former un joint latéral entre la limite d'un revêtement et une cloison.The present invention is susceptible of numerous variants which will appear to those skilled in the art. In particular, the cover profile may have various shapes, for example the usual shapes capable of satisfying the usual functions of forming a joint between coatings of variable and / or different heights, and so as to form a lateral joint between the limit of a covering and a partition.

De plus, comme cela est représenté, les profilés de recouvrement 25 et 35 des figures 2 et 3 sont légèrement creusés au niveau de leur face supérieure, ce qui permet d'appliquer sur ces profilés des bandes adhésives décoratives ou antidérapantes dont les bords seront protégés par des épaulements. In addition, as shown, the cover profiles 25 and 35 of Figures 2 and 3 are slightly hollowed out at their upper face, which allows to apply on these profiles decorative or non-slip adhesive strips whose edges will be protected by shoulders.
