Abstract
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, screwing to 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
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
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
En outre, la présente invention vise également à fournir une construction de dispositif d'habillage de marche favorisant la reprise des efforts appliqués sur le nez de marche.In addition, the present invention also aims to provide a walking cladding device construction promoting the recovery of forces applied to the nosing.
A cet effet, la présente invention a pour objet un dispositif d'habillage d'une marche d'escalier selon le préambule de la revendication 1 et faisant état des caractéristiques mentionnées dans la partie caractérisante de ladite revendication 1.For this purpose, the subject of the present invention is a device for cladding a staircase according to the preamble of claim 1 and making known the characteristics mentioned in the characterizing part of said claim 1.

Comme le montrent les
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
Le site de fixation 7 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 3, avec au moins un moyen d'engagement complémentaire 10 du second élément profilé 4, consistant en une aile profilée dont le bord de l'extrémité libre est muni latéralement d'une nervure 10' protubérante, ladite nervure 10' venant en prise ou en accrochage élastique sur le nez ou la corniche 7 lorsque le second élément profilé 4 est monté avec calage en position sur le premier élément profilé 3, ce après dépassement d'un point dur correspondant à une déformation de l'aile 10, en vue d'assurer un verrouillage, amovible ou libérable, du montage dudit second profilé 4 sur ledit premier élément profilé 3.The
Conformément à l'invention, 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 the invention, a
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
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
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
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
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
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
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

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
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
Selon un exemple de réalisation pratique, 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 an exemplary practical embodiment, a second
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
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
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
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
