Description

La présente invention concerne le domaine du bâtiment, en particulier des escaliers et, notamment la rénovation d'escaliers en bois ou l'habillage d'escaliers en béton et a pour objet un dispositif d'habillage destiné à cet effet.The present invention relates to the field of the building, especially stairs and, in particular the renovation of wooden stairs or the dressing of concrete stairs and has for object a covering device intended for this purpose.

Actuellement, la rénovation d'escaliers en bois est généralement réalisée par remplacement total de l'escalier existant, c'est-à-dire par démontage total de celui-ci et pose d'un nouvel escalier, ce qui entraîne une impossibilité d'utilisation dudit escalier pendant la durée du chantier ainsi que des désagréments liés à ce chantier, à savoir dépôt de poussière et autre et nécessité de refaire les plâtres et les tapisseries. Par ailleurs, ces travaux d'un coût élevé peuvent, dans certains cas, entraîner une impossibilité d'accès aux locaux des étages supérieurs.At present, the renovation of wooden staircases is generally carried out by total replacement of the existing staircase, that is to say by total disassembly of it and laying a new staircase, which entails an impossibility of use of said staircase during the duration of the site as well as inconvenience related to this site, namely dust deposit and other and need to redo the plasters and tapestries. Moreover, these works of a high cost may, in some cases, cause an impossibility of access to the premises of the upper floors.

Il est également courant de réaliser la rénovation par simple recouvrement au moyen d'une moquette ou d'un tapis en matière synthétique, solutions qui ne peuvent être considérées que comme provisoires.It is also common to carry out the renovation by simple covering with a carpet or carpet made of synthetic material, solutions that can only be considered temporary.

Les escaliers en bois présentent généralement une usure importante au milieu de chaque marche, alors que le limon et la rampe restent le plus souvent dans un excellent état. En outre, une rénovation d'un nez de marche en bois, usé, par recouvrement au moyen de bois est quasiment impossible avec les techniques actuelles.Wooden stairs usually have significant wear in the middle of each step, while the silt and ramp are most often in excellent condition. In addition, a renovation of a wooden stair nosing, worn, by covering with wood is almost impossible with current techniques.

Il a également été proposé, pour la réalisation de revêtements en bois de marches en béton, de fixer sur ces dernières et sur leurs contremarches, des planches ou panneaux en bois, leur maintien étant assuré par collage, par vissage aux extrémités et recouvrement par des limons rapportés. A cet effet, on connaît également un profilé fixé en extrémité de marche, sur l'arête de cette dernière, et pourvu de moyens de retenue d'un panneau de recouvrement de la marche et d'un panneau de recouvrement de la contre-marche.It has also been proposed, for the realization of wooden floorings of concrete steps, to fix on these and their risers, planks or wooden panels, their maintenance being ensured by gluing, by screwing at the ends and recovery by silt reported. For this purpose, a profile fixed at the walking end, on the edge thereof, and provided with means for retaining a covering panel of the step and a cover panel for the counter step are also known. .

Cependant, ce profilé connu ne permet pas la rénovation d'un escalier présentant des nez des marches en saillie, ni la réalisation de tels nez de marche, par exemple sur un escalier en béton.However, this known profile does not allow the renovation of a staircase with projecting steps, nor the realization of such stair nosing, for example on a concrete staircase.

Par le brevet français n° 2 736 078 , on connaît un dispositif d'habillage, en neuf ou en rénovation, permettant une adaptation à tous types d'escaliers en bois, ainsi que l'habillage en neuf de marches d'escaliers en béton, éventuellement avec création d'un nez de marche en saillie.By the patent French No. 2,736,078 , we know a dressing device, in nine or renovation, allowing adaptation to all types of wooden staircases, as well as the cladding of nine concrete staircases, possibly with the creation of a protruding stair nosing.

Bien qu'un tel dispositif surmonte les inconvénients exposés ci-dessus, il est relativement fastidieux à installer sur site du fait des très nombreux assemblages par vissage à réaliser et nécessite la mise en place d'un élément de recouvrement additionnel (par exemple sous la forme d'un joint) pour cacher les vis d'assemblage du profilé de nez de marche sur le profilé de base et de fixation.Although such a device overcomes the disadvantages described above, it is relatively tedious to install on site because of the many screw connections to be made and requires the establishment of an additional covering element (for example under the form of a gasket) to hide the assembly screws of the nosing profile on the base and fastening profile.

Par les documents DE-A-199 26 548 , EP-A-0 839 973 et EP-A-1 437 454 , on connaît des dispositifs d'habillage d'escalier constitués par des premiers profils de base, fixés sur les marches, et par des seconds profils formant nez de marche et retenant les éléments d'habillage.By the documents DE-A-199 26 548 , EP-A-0 839 973 and EP-A-1,437,454 , there are known staircase cladding devices consisting of first base profiles, fixed on the steps, and second profiles forming a stair nosing and retaining the cladding elements.

Les seconds profils sont assemblés avec les premiers profils par encastrement d'une aile pourvue de crans ou de stries d'un second profil dans une rainure crantée ou striée ménagée dans un premier profil associé.The second profiles are assembled with the first profiles by embedding a wing provided with notches or grooves of a second profile in a notched or serrated groove in a first associated profile.

Un tel montage, bien que limitant l'utilisation de vis de fixation ou d'assemblage, ne fournit pas un assemblage amovible. En effet, un désassemblage ne peut être réalisé qu'en forçant sur la liaison par enclenchement cranté, par exemple au moyen d'un pied de biche. Or, une telle opération de démontage forcé endommage irrémédiablement les crans d'assemblage, voire aboutit à une cassure de l'aile ou d'un des deux profilés, et n'autorise pas un remontage à l'identique en termes de qualité de l'assemblage. Il est donc nécessaire de remplacer les profilés après démontage.Such an assembly, while limiting the use of fastening screws or assembly, does not provide a removable assembly. Indeed, a disassembly can be achieved by forcing on the link by notched engagement, for example by means of a crowbar. However, such a forced disassembly operation irreparably damages the assembly notches, or even results in a breakage of the wing or one of the two profiles, and does not allow a reassembly identical in terms of quality of the assembly. 'assembly. It is therefore necessary to replace the profiles after disassembly.

La présente invention a pour but de fournir une solution aux inconvénients précités, en limitant le nombre de vis d'assemblage ou de fixation nécessaires, en permettant de s'affranchir de l'élément de recouvrement additionnel et en autorisant un démontage sans dégradation des profilés, ce tout en conservant tous les avantages du dispositif d'habillage connu du document FR-A-2 736 078 précité.The present invention aims to provide a solution to the aforementioned drawbacks, by limiting the number of screws assembly or fixing required, by eliminating the additional covering element and allowing disassembly without degradation of the profiles , while retaining all the advantages of the dressing device known from the document FR-A-2,736,078 supra.

A cet effet, la présente invention a pour objet un dispositif d'habillage, en neuf ou en rénovation, pour escalier ou analogue, comprenant essentiellement, pour chaque marche, d'une part, un premier élément profilé de fixation et de positionnement, à section sensiblement en forme de L et destiné à venir en application avec solidarisation, transversalement, sur le dessus de la marche et contre la contremarche ou le nez de marche existant, au moins au niveau de l'arête de la marche, et un second élément profilé formant nez de marche et également à section sensiblement en forme de L, les deux profilés étant destinés à être assemblés entre eux longitudinalement et à assurer en coopération le positionnement et le blocage en position d'un élément d'habillage de marche et d'un élément d'habillage de contremarche, le second élément recouvrant les bords longitudinaux des extrémités concourantes desdits éléments d'habillages et le premier élément profilé présentant, au niveau du côté extérieur de la zone de jonction de ses deux ailes constitutives, des sites de montage avec calage et de fixation pour le second élément profilé, destinés à coopérer avec des moyens complémentaires formés sur les faces internes des deux ailes constitutives dudit second élément profilé, dispositif d'habillage caractérisé en ce que le site de fixation consiste en au moins un site de verrouillage par enclenchement ou déformation élastique, sous la forme d'un nez ou d'une corniche profilé(e), destiné à coopérer, lors du montage de ce dernier sur le premier élément profilé, avec au moins un moyen d'engagement complémentaire du second élément profilé, consistant en une aile profilée dont le bord de l'extrémité libre est muni latéralement d'une nervure protubérante, ladite nervure venant en prise ou en accrochage élastique sur le nez ou la corniche lorsque le second élément profilé est monté avec calage en position sur le premier élément profilé, ce après dépassement d'un point dur correspondant à une déformation de l'aile, en vue d'assurer un verrouillage, amovible ou libérable, du montage dudit second profilé sur ledit premier élément profilé.For this purpose, the present invention relates to a covering device, in nine or renovation, for staircase or the like, essentially comprising, for each step, on the one hand, a first profiled element for fixing and positioning, to substantially L-shaped section and intended to come into application with solidarity, transversely, on the top of the step and against the riser or the existing stair nosing, at least at the edge of the step, and a second profiled member forming a step nosing and also substantially L-shaped section, the two sections being intended to be assembled together longitudinally and to ensure in cooperation the positioning and locking in position of a step trim element and a riser element, the second element covering the longitudinal edges of the concurrent ends of said cladding elements and the first profiled element having, at the outer side of the junction zone of its two constituent wings, mounting and securing means for the second profiled element, intended to cooperate with complementary means formed on the internal faces of the two wings constituting said second profiled element, dressing device characterized in that the fixing site consists of at least a locking site by interlocking or elastic deformation, in the form of a n nose or a profiled cornice (e), intended to cooperate, when mounting the latter on the first profiled element, with at least one additional engagement means of the second profiled element, consisting of a profiled wing whose edge the free end is provided laterally with a protruding rib, said rib engaging or elastic snap on the nose or cornice when the second profiled element is mounted in position with the first profiled element, after exceeding a hard point corresponding to a distortion of the wing, to ensure a lock, removable or releasable, mounting said second section on said first profiled element.

Le second élément profilé 4 recouvre les bords longitudinaux des extrémités concourantes desdits éléments d'habillages 5 et 6 et le premier élément profilé 3 présente, au niveau du côté extérieur de la zone de jonction de ses deux ailes constitutives 3' et 3", des sites de montage avec calage 8 et 9 et de fixation 7 pour le second élément profilé 4, ces sites étant destinés à coopérer avec des moyens complémentaires 10, 12 à 15 et 18 formés ou présents sur les faces internes des deux ailes constitutives 4' et 4" dudit second élément profilé 4.The second profiled element 4 covers the longitudinal edges of the concave ends of said cladding elements 5 and 6 and the first profiled element 3 has, at the outer side of the junction zone of its two constituent wings 3 'and 3 ", mounting sites with wedging 8 and 9 and fixing 7 for the second profiled element 4, these sites being intended to cooperate with complementary means 10, 12 to 15 and 18 formed or present on the inner faces of the two constituent wings 4 'and 4 "of said second profiled element 4.

Ainsi, la solidarisation du second élément profilé 4 avec le premier élément profilé 3 s'effectue sans mise en oeuvre d'un quelconque élément de fixation séparé, par simple "clipage". Ce montage peut, par conséquent, se faire sans outil et aucun élément de recouvrement additionnel n'est nécessaire pour cacher des éléments de fixation apparents.Thus, the securing of the second profiled element 4 with the first profiled element 3 takes place without implementation of any separate fastening element, by simple "clipping". This assembly can, for therefore, be tool-less and no additional overlap is needed to hide apparent fasteners.

De plus, une telle réalisation permet d'aboutir à une liaison très sûre et très résistante entre les deux éléments 3 et 4, puisqu'elle s'étend de manière continue sur une grande dimension (normalement sensiblement sur toute la largeur de la marche 2), tout en présentant un caractère amovible, sans dégradation.In addition, such an embodiment makes it possible to achieve a very safe and very strong connection between the two elements 3 and 4, since it extends continuously over a large dimension (normally substantially over the entire width of the step 2 ), while having a removable character, without degradation.

Avantageusement, le site de fixation ou de verrouillage 7 en forme de nez ou de corniche profilé(e) est situé(e) en surplomb au-dessus d'une rainure profilée 7' ménagée dans le premier élément profilé 3.Advantageously, the fixation or locking site 7 in the form of a profiled nose or cornice (e) is located (e) overhanging above a profiled groove 7 'formed in the first profiled element 3.

Afin de faciliter l'assemblage des deux éléments 3 et 4, le site 7 peut présenter une surface inclinée 11 de guidage et de déformation progressive du moyen d'engagement complémentaire 10 du second élément profilé 4, pendant le mouvement de montage guidé de ce dernier en vue de son assemblage avec le premier élément profilé 3, ce jusqu'à obtention de l'état enclenché ou accroché dudit site 7 avec ledit moyen 10.In order to facilitate the assembly of the two elements 3 and 4, the site 7 may have an inclined surface 11 for guiding and progressively deforming the complementary engagement means 10 of the second profiled element 4, during the guided mounting movement of the latter with a view to its assembly with the first profiled element 3, until the engaged or hooked state of said site 7 is reached with said means 10.

En vue d'autoriser un démontage sans effort excessif et sans risque d'endommagement des éléments 3 et 4, le nez ou la corniche 7 formant site de fixation ou de verrouillage vient en prise, sur la nervure 10' du moyen d'engagement 10, au niveau d'une surface plane inclinée 10" de celle-ci, autorisant un désengagement dudit site 7 d'avec ledit moyen d'engagement 10 par sollicitation du second élément profilé 4 dans une direction D' opposée à la direction D du mouvement de montage ou d'assemblage, par une déformation progressive de l'aile 10 formant ledit moyen d'engagement complémentaire sous l'action du nez ou de la corniche 7 en appui sur ladite surface plane inclinée 10" de la nervure 10'.In order to allow disassembly without excessive effort and without risk of damage to the elements 3 and 4, the nose or the cornice 7 forming the attachment or locking site engages on the rib 10 'of the engagement means 10 at an inclined flat surface 10 "thereof, allowing disengagement of said site 7 from said engagement means 10 by biasing the second profiled member 4 in a direction D 'opposite the direction D of the movement mounting or assembly, by a progressive deformation of the wing 10 forming said complementary engagement means under the action of the nose or cornice 7 resting on said inclined plane surface 10 "of the rib 10 '.

Conformément à une autre caractéristique de l'invention ne ressortant pas des dessins annexés, il peut être prévu que l'aile 10 formant le moyen d'engagement complémentaire soit dépourvue de la nervure protubérante 10' sur une longueur déterminée au niveau de l'une des deux extrémités longitudinales du second élément profilé 4.According to another feature of the invention not apparent from the accompanying drawings, it may be provided that the wing 10 forming the complementary engagement means is devoid of the protruding rib 10 'over a length determined at one two longitudinal ends of the second profiled element 4.

Une telle réalisation de l'aile 10 (obtenue par exemple par enlèvement par limage de la nervure 10' à l'une des extrémités longitudinales de l'aile 10 du premier élément profilé 3 découpé à la largeur de la marche) permet de créer une zone d'amorçage facilitant la désolidarisation, sans compromettre la solidité de la liaison entre les éléments 3 et 4 à l'état assemblé.Such an embodiment of the wing 10 (obtained for example by removal by filing the rib 10 'at one of the longitudinal ends of the flange 10 of the first profiled element 3 cut to the width of the step) allows to create a priming zone facilitating the disconnection, without compromising the strength of the connection between the elements 3 and 4 in the assembled state.

Conformément à une autre caractéristique avantageuse de l'invention ressortant également des figures 1 à 3 annexées, le premier élément profilé 3 comporte deux sites 8 et 9 de montage avec calage pour le second élément profilé 4, situés de part et d'autre du site de fixation ou de verrouillage 7 et assurant un support dudit second élément profilé 4 par ledit premier élément profilé 3 avec calage dans une direction DP perpendiculaire au plan défini conjointement par la direction d'appui DA du second élément profilé 4 sur le premier élément profilé 3 et par la direction longitudinale DL (direction de profilage) des premier et second éléments profilés 3 et 4 à l'état assemblé.According to another advantageous characteristic of the invention also apparent from the appended FIGS. 1 to 3, the first profiled element 3 comprises two wedge mounting sites 8 and 9 for the second profiled element 4, located on either side of the site. fixing or locking device 7 and providing a support for said second profiled element 4 by said first profiled element 3 with wedging in a direction DP perpendicular to the plane defined jointly by the support direction DA of the second profiled element 4 on the first profiled element 3 and by the longitudinal direction DL (profiling direction) of the first and second profiled elements 3 and 4 in the assembled state.

Préférentiellement, chaque site de montage avec calage 8, 9 du premier élément profilé 3 présente une surface d'appui 8', 9' profilée, éventuellement décalées l'une par rapport à l'autre mais toutes deux situées dans des plans parallèles au plan de l'aile 3' du premier élément profilé 3 venant en application sur le dessus 2' de la marche concernée, des surfaces d'appui conjuguées 12, 13 respectivement correspondantes et présentes sur le second élément profilé 4 reposant sur ces surfaces d'appui 8', 9' du premier élément profilé 3 à l'état monté ou assemblé de ces deux éléments profilés 3 et 4. En outre, chaque site de montage avec calage 8, 9 présente une surface de calage profilée 8", 9", situées chacune dans un plan perpendiculaire au plan de la surface d'appui 8', 9' correspondante et assurant ensemble, d'une part, le guidage du second élément profilé 4 par rapport au premier élément profilé 3, au moins lors de la phase finale du mouvement de montage et durant la phase d'enclenchement du moyen d'engagement complémentaire 10 au niveau du site de verrouillage 7 et, d'autre part, un calage en position à l'état monté du second élément profilé 4 par rapport au premier élément profilé 3 dans la direction DP, ce par coopération en contact surfacique avec des surfaces de calage et de guidage conjuguées 14, 15 respectivement correspondantes présentes au niveau du second élément profilé 4.Preferably, each wedged mounting site 8, 9 of the first profiled element 3 has a profiled bearing surface 8 ', 9', possibly offset relative to each other but both located in planes parallel to the plane of the wing 3 'of the first profiled element 3 coming into application on the top 2' of the step concerned, respectively corresponding matching bearing surfaces 12, 13 and present on the second profiled element 4 resting on these bearing surfaces 8 ', 9' of the first profiled element 3 in assembled or assembled state of these two profiled elements 3 and 4. In addition, each wedged mounting site 8, 9 has a profiled wedging surface 8 ", 9", each located in a plane perpendicular to the plane of the corresponding bearing surface 8 ', 9' and together, on the one hand, guiding the second profiled element 4 relative to the first profiled element 3, at least during the phase final of the movement of assembly and during the engagement phase of the complementary engagement means 10 at the locking site 7 and, secondly, a positional setting in the mounted state of the second profiled element 4 relative to the first profiled element 3 in the DP direction, by cooperation in surface contact with mating matching and matching wedging surfaces 14, 15 respectively present at the second profiled element 4.

On aboutit ainsi à une dissociation de la fonction de verrouillage de l'assemblage des éléments 3 et 4 (réalisée par 7 et 10) d'avec la fonction de reprise d'efforts et de sollicitations entre ces éléments 3 et 4 (réalisée par 8, 9 et 12 à 15).This leads to a dissociation of the locking function of the assembly of the elements 3 and 4 (carried out by 7 and 10) with the function of taking up forces and stresses between these elements 3 and 4 (performed by 8 , 9 and 12 to 15).

Selon un premier exemple de réalisation pratique, un premier site 8 de montage avec calage du premier élément profilé 3 correspond à une lèvre, formée au niveau de la zone de jonction de ses deux ailes constitutives 3', 3" et proéminente vers l'extérieur par rapport à l'aile 3" du premier élément profilé 3 venant en application sur le nez de marche existant 2"' ou sur la contremarche 2", le rebord 16 relevé de ladite lèvre 8 définissant une surface d'appui profilée plane 8' et une surface de calage et de guidage plane 8", le second élément profilé 4 comportant, au niveau de la face interne de son aile 4" destinée à maintenir l'élément d'habillage 6 de la contremarche 24, une surface d'appui conjuguée 12 formée au niveau d'un épaulement interne et une surface de guidage et de calage conjuguée 14 formée sur la face interne de ladite aile 4" et débouchant sur ledit épaulement.According to a first practical example, a first mounting site 8 with wedging of the first profiled element 3 corresponds to a lip formed at the junction zone of its two wings. 3 ', 3 "and protruding outwardly with respect to the wing 3" of the first profiled member 3 applying to the existing stair nose 2 "' or the riser 2", the rim 16 raised from said lip 8 defining a planar profiled bearing surface 8 'and a flat wedging and guide surface 8 ", the second profiled element 4 comprising, at the inner face of its flange 4" intended to hold the element of cladding 6 of the riser 24, a mating bearing surface 12 formed at an internal shoulder and a conjugate guide and wedging surface 14 formed on the inner face of said flange 4 "and opening on said shoulder.

Selon un second exemple de réalisation pratique, éventuellement coexistant avec le premier exemple précité, un second site de montage avec calage 9 est constitué par l'association d'une bande de surface d'appui profilée 9' définie sur l'aile 3' constitutive du premier élément profilé 3 venant en application sur le dessus 2' de la marche et d'une surface de guidage et de calage 9" constituée par une face d'une aile proéminente profilée 17 s'étendant perpendiculairement à partir de ladite aile 3' constitutive, le second élément profilé 4 présentant une aile interne profilée 18 dont le bord libre définit une surface d'appui conjuguée 13 correspondante et dont l'une des faces latérales définit la surface de guidage et de calage conjuguée 15 correspondante.According to a second example of practical embodiment, possibly coexisting with the aforementioned first example, a second wedging mounting site 9 is constituted by the association of a profiled bearing surface band 9 'defined on the wing 3' constituting the first profiled element 3 coming into application on the top 2 'of the step and a guide and wedging surface 9 "constituted by a face of a profiled prominent flange 17 extending perpendicularly from said flange 3' constitutive, the second profiled element 4 having a profiled inner flange 18 whose free edge defines a corresponding mating bearing surface 13 and one of the side faces defines the corresponding conjugate guide and wedging surface 15.

Lors du mouvement d'assemblage du second élément profilé 4 par rapport au premier élément profilé 3, résultant en un engagement mutuel progressif de ces éléments profilés 3 et 4, un guidage simple ou double est fourni par l'appui glissant de l'aile interne 18 sur l'aile proéminente 17 et/ou par l'appui glissant de la face interne de l'aile 4" sur le rebord 16 de la lèvre 8. Cet appui permet de provoquer par poussée sur le second profilé en direction du premier profilé la déformation élastique de l'aile 10.During the assembly movement of the second profiled element 4 relative to the first profiled element 3, resulting in a progressive mutual engagement of these profiled elements 3 and 4, a single or double guide is provided by the sliding support of the inner wing 18 on the prominent flange 17 and / or by the sliding support of the inner face of the flange 4 "on the flange 16 of the lip 8. This support allows to cause by pushing on the second section towards the first section the elastic deformation of the wing 10.

En vue de pouvoir éventuellement réaliser la fixation d'un élément d'habillage de nez de marche (non représenté sur les figures annexées), le dispositif 1 peut, en outre, comprendre un troisième élément profilé 19 à section en T ou en L, pouvant être solidarisé, de manière réglable en hauteur, sur la face interne de l'aile 3' du premier élément profilé 3 venant en application contre le nez de marche existant ou la contremarche, par imbrication mutuelle de formations protubérantes profilées 20 définissant des rainures et des nervures de formes complémentaires sur ladite face interne de l'aile 3' et sur une face d'assemblage correspondante de l'une des ailes dudit troisième élément profilé en T ou en L.In order to possibly be able to fix a step nosing element (not shown in the appended figures), the device 1 may furthermore comprise a third T-shaped or L-shaped profiled element 19. being able to be fixed, in a height-adjustable manner, on the internal face of the wing 3 'of the first profiled element 3 coming into application against the existing stair nosing or the riser, by mutual interweaving of profiled protruding formations 20 defining grooves and ribs of shapes complementary on said inner face of the wing 3 'and on a corresponding assembly face of one of the wings of said third element T-shaped or L-shaped.

Avantageusement, le premier et le second élément profilé 3 et 4, ainsi que, le cas échéant, le troisième élément profilé 19, consistent en des profilés extrudés en aluminium ou en alliage à base d'aluminium et en ce que les éléments d'habillage 5 et 6 consistent en des plaques de bois ou de parquet artificiel.Advantageously, the first and the second profiled element 3 and 4, as well as, where appropriate, the third profiled element 19, consist of extruded profiles made of aluminum or aluminum-based alloy and in that the cladding elements 5 and 6 consist of plates of wood or artificial parquet.

Grâce à l'invention, des vis de fixation ne seront mises en oeuvre que pour la solidarisation du premier élément profilé 3 sur le dessus 2' de la marche 2 et le nez de marche 2"' ou la contremarche 2".Thanks to the invention, fixing screws will be implemented only for securing the first profiled element 3 on the top 2 'of the step 2 and the step nosing 2 "' or the riser 2".

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés.
