Abstract
Description
L'invention concerne un escalier et un système de marches d'escalier modulaire apte à être monté/démonté et pouvant être réglé selon différentes configurations.The invention relates to a staircase and a modular stair step system adapted to be mounted / disassembled and adjustable in different configurations.
Outre leur largeur, les marches d'escaliers se caractérisent notamment par leur giron et leur hauteur. Le rapport entre ces deux paramètres définit la pente et détermine le confort de marche et est établi à l'aide la formule de Blondel : 60 < (2 x Hauteur) + Giron < 64.In addition to their width, the steps are characterized by their lap and their height. The ratio between these two parameters defines the slope and determines the walking comfort and is established using the Blondel formula: 60 <(2 x Height) + Giron <64.
Dans la technique antérieure des escaliers préfabriqués à monter, un ensemble de marches constitue généralement un bloc monolithique. Cette solution impose une mise en oeuvre par soudure sur site. Mis à part l'absence de flexibilité et l'infrastructure nécessaire à une telle mise en oeuvre in situ, cette solution ne permet pas de réglage ni de correction possible après coup. Elle ne permet pas de démontage ultérieur sans altérer l'ouvrage lui-même. Chaque élément constituant est mesuré et découpé selon des dimensions précises. Cette solution impose une étude et une fabrication sur mesure, précise, et au cas par cas.In the prior art of prefabricated stairs to climb, a set of steps is usually a monolithic block. This solution requires implementation by welding on site. Apart from the lack of flexibility and the infrastructure necessary for such an implementation in situ, this solution does not allow adjustment or possible correction after the fact. It does not allow subsequent disassembly without altering the structure itself. Each constituent element is measured and cut to precise dimensions. This solution requires a study and a custom made, precise, and case by case.
Là ou l'élément "monolithique" impose donc une fabrication spécifique pour chaque situation en fonction du giron et de la hauteur de marche.Where the "monolithic" element imposes a specific manufacture for each situation according to the lap and the walking height.
La présente invention propose une adaptation à un large éventail de cas. Lors du montage le giron et la hauteur des marches modulaires présentent une marge de manoeuvre pour répondre aux cas qui rentrent dans la formule de Blondel, fréquemment d'usage par l'homme de métier.The present invention provides adaptation to a wide range of cases. During assembly the tread and the height of the modular steps have room for maneuver to respond to cases that fit into the Blondel formula, frequently used by the skilled person.
Le but de l'invention est atteint en proposant un élément de marche selon la revendication 1 en annexe et un procédé de fabrication, accompagnés de caractéristiques mentionnées dans les revendications dépendantes.The object of the invention is achieved by providing a step member according to
L'élément de marche de la présente invention constitue un élément d'un système modulaire indépendant permettant l'assemblage d'une volée de marches dont la pente, donc la hauteur et le giron de chacune des marches est ajustable. Selon une forme de réalisation, tous les éléments modulaires sont de même dimensions, de même structure et de même forme. Avantageusement, chaque élément peut être symétrique par rapport à un point situé au milieu du plat de marche. Les marches sont reliées mécaniquement entre elles par des boulons, vis ou éléments de fixation équivalents.
Selon l'invention, l'indépendance de chacune des marches permet notamment un réglage fin de leur aplomb, de leur horizontalité et de leur inclinaison. La fixation mécanique permet les réglages précis. Ces fixations n'étant pas définitives elle permettent de corriger tant la position de la marche elle-même, ses éventuelles fluctuations ou dilatations que les éventuelles imperfections indépendantes de l'élément modulaire lui-même, tel que par exemple l'aplomb ou la planéité du mur support.The walking element of the present invention is an element of an independent modular system for assembling a flight of steps whose slope, so the height and the tread of each of the steps is adjustable. According to one embodiment, all the modular elements are of the same dimensions, of the same structure and of the same shape. Advantageously, each element may be symmetrical with respect to a point located in the middle of the walking dish. The steps are mechanically connected to each other by bolts, screws or equivalent fasteners.
According to the invention, the independence of each of the steps allows in particular a fine adjustment of their plumb, their horizontality and their inclination. Mechanical fixation allows precise adjustments. These fixations are not definitive, they make it possible to correct both the position of the step itself, its possible fluctuations or expansions, and any possible imperfections independent of the modular element itself, such as, for example, plumb or flatness. of the support wall.
L'invention propose donc une marche modulaire constituant un ensemble limon de jour, plat de la marche et limon de nuit. Chaque élément de marche peut être connecté à une marche identique supérieure et une marche identique inférieure. Il est prévu des moyens de fixations entre les éléments de marche au niveau des limons. On obtient ainsi un escalier à limon discontinu.The invention therefore proposes a modular step constituting a set of daytime limon, flat walk and night slime. Each step element can be connected to a higher identical step and a lower identical step. Fixing means are provided between the walking elements at the level of the slats. We thus obtain a staircase with discontinuous slime.
De manière générale, l'invention propose un élément de marche pour escalier modulaire comprenant un giron et deux éléments plats de limon s'étendant perpendiculairement à chaque extrémité du giron, l'un en direction opposée de l'autre, les éléments de limon comprenant des orifices de fixation aptes à coopérer avec des éléments de limon correspondant d'une marche modulaire identique ou similaire adjacente.In general, the invention provides a step element for a modular staircase comprising a tread and two flat members of stringer extending perpendicularly to each end of the tread, one in the opposite direction of the other, the stringer elements comprising fixing holes adapted to cooperate with corresponding silt elements of an identical modular step or similar adjacent.
Les moyens de fixations comprennent de préférence des pattes plaques de fixation comportant des encoches ou rosaces coopérant avec des rosaces ou encoches des pattes de limon adjacente. La fixation elle-même peut être obtenue par des boulons traversant une rosace de réglage et une encoche en forme de boutonnière, ou selon un autre mode de réalisations deux boutonnières non parallèles.The fastening means preferably comprise tabs fastening plates having notches or rosettes cooperating with rosettes or notches tabs of adjacent silt. The fastener itself can be obtained by bolts passing through an adjusting rosette and a notch in the form of a buttonhole, or according to another embodiment of two non-parallel buttonholes.
Selon un mode de réalisation, chaque marche modulaire est à relier à sa réplique parfaite. L'ajout d'une marche se fait par pivotement de 180° d'un nouvel élément par rapport à la marche déjà placée. Par ce pivotement, les pattes sont présentées de sorte à pouvoir s'imbriquer par superposition.According to one embodiment, each modular step is to be connected to its perfect replica. The addition of a step is made by pivoting by 180 ° of a new element with respect to the step already placed. By this pivoting, the tabs are presented so as to overlap by superposition.
Aucun autre élément modulaire que la marche elle-même n'est nécessaire pour compléter un escalier. Il suffit de prendre une nouvelle marche modulaire identique et de la faire pivoter pour présenter la marche supplémentaire de sorte que les pattes, les limons de chacune des marches, entre l'une dans l'autre.No other modular element than walking itself is needed to complete a staircase. Just take a new identical modular step and rotate it to present the extra step so that the legs, the strings of each step, between one in the other.
Du fait de la modularité de la marche, et de sa forme en "S", le stockage et le transport sont rationnels. Chaque marche se loge sur sa réplique et ainsi de suite.Due to the modularity of the step, and its "S" shape, storage and transport are rational. Each market is lodged on its replica and so on.
Selon un premier mode de réalisation l'ensemble de la marche est essentiellement formée d'une feuille métallique pliée à laquelle on aura préalablement soudé les pièces pour l'emboîtement des limons. Ces limons sont constitués de plats de moitié moins épais que l'épaisseur du plat de la marche. De cette façon chaque patte de limon sont dans deux plans parallèles mais non coplanaires et peuvent ainsi s'enchâsser. Le tout forme un seul ensemble usiné. La marche ainsi constituée rassemble tant le limon de nuit, que le giron de la marche et que le limon de jour et cet ensemble forme une seule pièce modulaire.According to a first embodiment, the whole of the step is essentially formed of a folded metal sheet to which the parts will have been previously welded for the nesting of the stringers. These silts consist of dishes half as thick as the thickness of the tread. In this way each lime leg is in two parallel planes but not coplanar and can thus be buried. All forms a single machined assembly. The march thus constituted gathers together the night silt, the walking tread and the silt of day and this set forms a single modular piece.
En fonction de la hauteur et de la profondeur choisie, les encoches ( ou boutonnières) se présenteront en positions différentes l'une par rapport à l'autre. Selon un mode de réalisation, au droit des limons, les marches modulaires sont pourvues d'une encoche horizontale permettant les réglages horizontal du giron de la marche d'une part. D'autre part elles sont pourvues d'un percement en rosace qui pourrait être muni, par exemple, d'un pas de vis. Ce percement rond peut recevoir une pastille circulaire métallique, elle même percée d'un trou décentré par rapport au centre de la pastille. Cette pièce permet l'ajustement du trou décentré, à l'encoche horizontale de l'autre module à laquelle la marche doit se fixer. Une fois ces éléments ajustés la fixation mécanique pourra être enchâssée à travers les trous laissés, puis boulonnés ou vissés suivant la méthode préférée de l'invention. Outre cette fixation mécanique de la marche elle-même, la rosace sera elle aussi fixée mécaniquement pour éviter toute rotation et ainsi empêcher la fluctuation des ajustements.Depending on the height and the depth chosen, the notches (or buttonholes) will be in different positions relative to each other. According to one embodiment, at the right of the stringers, the modular steps are provided with a horizontal notch allowing the horizontal adjustment of the tread of the march on the one hand. On the other hand they are provided with a rosette piercing which could be provided, for example, with a thread. This round piercing can receive a circular metal pellet, itself pierced with a hole off center of the center of the pellet. This part allows the adjustment of the off-center hole to the horizontal notch of the other module to which the step must be fixed. Once these elements have been adjusted, the mechanical fastening can be enshrined through the holes left, then bolted or screwed according to the preferred method of the invention. In addition to this mechanical attachment of the step itself, the rosette will also be mechanically fixed to prevent rotation and thus prevent the fluctuation of adjustments.
Chaque limon, c'est à dire de jour et de nuit, constituant le module doit présenter ces deux encoches pour le passage des fixation mécanique et le blocage des éléments entre eux.Each silt, that is to say day and night, constituting the module must have these two notches for the passage of mechanical fixing and blocking elements between them.
Suivant la méthode susmentionneé de l'invention, le percement circulaire en rosace et la pastille sont tous deux taraudés pour permettre l'ancrage stable entre l'un et l'autre.
Une variante possible serait d'intégrer la pastille dans la loge du percement circulaire tout en permettant la rotation libre et stable de la pastille, de manière à assurer l'ancrage de celle-ci à la marche modulaire.According to the aforementioned method of the invention, the circular hole rosette and the pellet are both threaded to allow stable anchoring between one and the other.
A possible variant would be to integrate the pellet in the box of the circular piercing while allowing the free and stable rotation of the pellet, so as to ensure the anchoring thereof to the modular step.
Pour assurer le calage des éléments modulaires entre les marches elles-mêmes, deux encoches sont découpées sur chacun des limons uniformément intégrés dans le module de marche l'une oblongue, l'autre circulaire. Ces pattes de limon sont constitués par exemple de soudure d'éléments de moitié d'épaisseur que le plat de la marche, afin que chaque patte de limon soit dans deux plans parallèles mais non coplanaires. Chaque patte d'emboîtement présente un des deux types d'encoches. Chaque type d'encoche doit être présent sur chacun des limons, de part et d'autre de la largeur de la marche.To ensure the wedging of the modular elements between the steps themselves, two notches are cut on each of the strings uniformly integrated in the walking module one oblong, the other circular. These lime legs consist for example of welding half-thick elements that the flat of the step, so that each leg silt is in two parallel planes but not coplanar. Each interlocking lug has one of two types of notches. Each type of notch must be present on each of the stringers, on either side of the width of the step.
Selon ce mode de réalisation, chaque nouvel élément peut être raccordé à un autre en utilisant le même module mais pivoté à 180° autour d'un axe horizontal parcourant la larguer de la marche. Chaque patte des différents modules qui vont être accolés présente chacune une encoche différente par rapport à l'autre. L'une circulaire, l'autre oblongue et horizontale.According to this embodiment, each new element can be connected to another using the same module but rotated 180 ° about a horizontal axis traversing the drop of the step. Each leg of the different modules that will be contiguous each has a notch different from the other. One circular, the other oblong and horizontal.
Selon un autre mode de réalisation le raccord se fait grâce à des éléments de fixation en coordination avec une boutonnière oblique et une boutonnière horizontale chacune présente sur chaque limon et s'ajustant respectivement avec une boutonnère horizontale et oblique d'un limon d'une marche adjacente.According to another embodiment the connection is made through fastening elements in coordination with an oblique buttonhole and a horizontal buttonhole each present on each stringer and fitting respectively with a horizontal and oblique buttonhole of a stringer of a step adjacent.
Suivant la méthode préférée de l'invention, l'escalier est adossé à un mur et les marches sont toujours raccordées les unes aux autres de sorte que les moments des forces à l'opposé de l'ancrage du mur puissent être transmis d'une marche à l'autre, ou d'un marche au palier, et ainsi répartir la charge.According to the preferred method of the invention, the staircase is leaned against a wall and the steps are always connected to each other so that the moments of the forces opposite the anchoring of the wall can be transmitted from one to the other. walk to another, or a step to the landing, and thus distribute the load.
Une variante possible consiste à consolider les marches entre elles au-delà de la suivante ou la précédente, en reliant l'ensemble des marches à l'aide d'un ou deux câbles fixés d'un élément "limon de jour" à l'autre, sur chacune des pattes constitutives du module de marche, fixés ensemble avec l'élément de fixation mécanique passant à travers les encoches et bloquant les marches.One possible variant is to consolidate the steps between them beyond the next or the previous one, by connecting all the steps using one or two cables fixed with a "daylight" element to the other, on each of the component tabs of the walking module, fixed together with the mechanical fastener passing through the notches and blocking the steps.
Une autre variante possible est celle qui vise à consolider les marches entre elles au-delà de la suivante ou la précédente, en reliant l'ensemble des marches à l'aide d'un ou deux profilés tubulaires ronds fixés ensemble avec l'élément de fixation mécanique passant à travers les encoches et bloquant les marches.Another possible variant is that which aims to consolidate the steps between them beyond the next or the previous one, by connecting all the steps using one or two round tubular profiles secured together with the element of mechanical fastener passing through the notches and blocking the steps.

- des tiges filetées peuvent être ancrées (par exemple par ancrage chimique) dans le mur et rester en attente de la pose d'une marche. Il est possible alors d'enfiler une première marche puis une marche suivante par les tiges filetées. La mise en oeuvre s'opère donc en 3 étapes :
placement 1. de la tige filetée, 2 première marche, 3 seconde marche. - dans le cas d'une marche en tôle qui est le matériau actuellement préféré, aucun autre usinage n'est nécessaire autre que découpe et pliage. Aucune soudure ne doit être effectuée.
- threaded rods can be anchored (for example by chemical anchoring) in the wall and remain waiting for a step. It is then possible to put on a first step then a next step by the threaded rods. The implementation takes place in 3 steps: 1. placement of the threaded rod, 2 first step, 3 second step.
- in the case of a sheet metal step which is the currently preferred material, no further machining is necessary other than cutting and bending. No soldering should be done.
Un gabarit sur papier peut être utilisé pour positionner les ancrages au fur et à mesure du montage suivant les dimensions souhaitées et disponibles.A template on paper can be used to position the anchors as and when mounting according to the desired dimensions and available.
