Description

L'invention se rapporte à un élément préfabriqué pour la construction d'escalier et aux escaliers obtenus par assemblage de tels éléments.The invention relates to a prefabricated element for the construction of stairs and to the stairs obtained by assembling such elements.

Elle s'applique plus particulièrement mais non exclusivement à la réalisation d'escaliers droits et/ou en colimaçon avec ou non des éléments combinés.It applies more particularly but not exclusively to the realization of straight and / or spiral staircases with or without combined elements.

On connaît déjà (FR-A-2.520.418) des éléments préfabriqués permettant de réaliser des escaliers droits, courbes et/ou en colimaçon.We already know (FR-A-2,520,418) prefabricated elements making it possible to produce straight, curved and / or spiral staircases.

Ces éléments connus forment chacun à la fois un des éléments de la structure porteuse et une des marches de cet escalier. Pour cela, ces éléments qui ont en plan une section circulaire sont principalement formés d'un plateau qui réalise le dessus de la marche ainsi que d'un fond bombé ayant une section verticale semi-elliptique pour offrir un bord périphérique qui soutient le plateau et pour réaliser son entretoisement par rapport au plateau d'un autre élément.These known elements each form both one of the elements of the supporting structure and one of the steps of this staircase. For this, these elements which have in plan a circular section are mainly formed of a plate which realizes the top of the step as well as a curved bottom having a vertical semi-elliptical section to offer a peripheral edge which supports the plate and to perform its bracing with respect to the plate of another element.

Pour leur assemblage, ils font appel à des ferrures de liaison. Ces éléments qui, en plan, sont décalés l'un de l'autre d'environ un demi élément présentent chacun des perçages dont un perçage central d'axe vertical et tout une série de perçages d'axe horizontal répartis sur un cercle situé à sa périphérie. Une ferrure est fixée, d'une part, dans le trou central d'un élément et sur la périphérie de l'autre élément qui, du fait du décalage, sert d'appui ou au moins passe environ sous le centre du premier élément tandis que deux autres ferrures sont fixées sur la périphérie des deux éléments à assembler aux deux points où, en plan, se coupent les cercles des perçages périphériques. Ces éléments limitent les possibilités de forme de plateau de marche et demandent des opérations complexes d'assemblage. On connaît aussi (FR-A-2.035.457 ) des éléments modulaires comprenant une ossature telle un tube cylindrique présentant à ses extrémités de deux pièces d'appui pourvues chacune de moyens complémentaires d'assemblage répartis de manière que l'assemblage entre des éléments puissent se faire par superposition exacte des cercles des pièces d'appui juxtaposées quelle que soit leur orientation réciproque.For their assembly, they use connecting fittings. These elements which, in plan, are offset from each other by about a half element each have holes including a central hole with a vertical axis and a whole series of holes with a horizontal axis distributed over a circle located at its periphery. A fitting is fixed, on the one hand, in the central hole of one element and on the periphery of the other element which, due to the offset, serves as a support or at least passes approximately under the center of the first element while that two other fittings are fixed on the periphery of the two elements to be assembled at the two points where, in plan, the circles of the peripheral holes intersect. These elements limit the possibilities of the shape of a step plate and require complex assembly operations. There are also known (FR-A-2,035,457) modular elements comprising a framework such as a cylindrical tube having at its ends two support pieces each provided with complementary assembly means distributed so that the assembly between elements can be done by exact superimposition of the circles of juxtaposed support pieces regardless of their mutual orientation.

Dans ce brevet, les pièces d'appui consistent en des rondelles soudées à l'intérieur du tube de l'ossature légèrement en retrait des faces extrêmes.In this patent, the support pieces consist of washers welded to the inside of the frame tube slightly set back from the end faces.

Pour accéder aux moyens d'assemblage, le tube est perçé d'un orifice .To access the assembly means, the tube is pierced with an orifice.

La mise en place des éléments d'assemblage en passant par cet orifice, se fait toutefois sans aucune visibilité, ce qui rend le montage extrêmement complexe.The installation of the assembly elements passing through this orifice, however, is done without any visibility, which makes the assembly extremely complex.

Les pièces d'appui sont en outre disposées de manière à réaliser un emboîtement d'un élément par rapport à l'autre, ceci pour assurer une continuité du faux montant.The support pieces are also arranged so as to make an interlocking of one element with respect to the other, this to ensure continuity of the false upright.

Cela interdit toutefois d'intercaler entre les éléments des plateaux réalisant des marches, et de ce fait, celles-ci font appel, pour leur fixation, à des moyens distincts portés par la face externe du cylindre à proximité de l'orifice laissant accès à l'intérieur de l'ossature.However, this prohibits interposing between the elements of the plates making steps, and therefore, they use, for their fixing, separate means carried by the external face of the cylinder near the orifice giving access to inside the frame.

Cela ne permet pas d'orienter la marche par rapport à l'ossature et, en conséquence, ne permet pas de réaliser des escaliers à la fois orientables et inclinés.This does not make it possible to orient the step with respect to the framework and, consequently, does not make it possible to make stairs which are both orientable and inclined.

En outre, cela ne permet pas la fixation d'organes de soutien des marches à moins de prévoir encore d'autres éléments distincts de ceux assurant l'assemblage des éléments entre eux. Un résultat que l'invention vise à obtenir est un élément permettant de réaliser des escaliers dont l'assemblage est aisé et qui laisse libre choix aux constructeurs tant de la forme des plateaux de marche que de l'inclinaison de l'escalier mais surtout qui, pour porter les marches, ne fait appel à aucun autre moyen d'assemblage que ceux nécessairement prévus pour relier les éléments entre eux.In addition, this does not allow the fixing of market support members unless there are still other elements separate from those ensuring the assembly of the elements together. A result which the invention aims to obtain is an element making it possible to produce stairs which are easy to assemble and which leaves manufacturers free choice both of the shape of the walking platforms and of the inclination of the staircase but above all which , to carry the steps, does not use any other means of assembly than those necessarily provided to connect the elements together.

A cet effet, elle a pour objet un élément du type précité notamment caractérisé en ce que c'est dans les plans de chacune des extrémités de son ossature que chaque élément présente ses deux pièces d'appui, en ce que ces pièces d'appui viennent latéralement en saillie vers l'extérieur de l'ossature et réalise des brides parallèles entre elles et en ce que l'une de ces brides au moins concourt à la réalisation d'un plateau de marche.To this end, it relates to an element of the aforementioned type, in particular characterized in that it is in the planes of each of the ends of its framework that each element has its two support pieces, in that these support pieces come laterally projecting towards the outside of the frame and produces flanges parallel to each other and in that one of these flanges at least contributes to the production of a step plate.

Elle a également pour objet les escaliers obtenus par assemblage de tels éléments.It also relates to the stairs obtained by assembling such elements.

L'invention sera mieux comprise à l'aide de la description ci-après faite, à titre d'exemple non limitatif, en regard du dessin ci-annexé qui représente schématiquement :

  • - figure 1 un élément entrant dans la réalisation d'un escalier en colimaçon,
  • - figure 2 : un élement entrant dans la réalisation. d'un escalier dit droit,
  • - figure 3 : un escalier en colimaçon réalisé exclusivement avec des éléments du type représenté en figure 1,
  • - figure 4 : un escalier droit réalisé avec des éléments du type représenté en figure 2,
  • - figures 5 et 6 : des variantes de réalisation de l'élément,
  • - figure 7 : un exemple d'escalier réalisé avec des éléments du type représenté figures 1 et 2
The invention will be better understood with the aid of the description below, given by way of nonlimiting example, with reference to the attached drawing which schematically represents:
  • - Figure 1 an element used in the realization of a spiral staircase,
  • - Figure 2: an element entering the realization. a straight staircase,
  • - Figure 3: a spiral staircase made exclusively with elements of the type shown in Figure 1,
  • FIG. 4: a straight staircase made with elements of the type shown in FIG. 2,
  • - Figures 5 and 6: alternative embodiments of the element,
  • - Figure 7: an example of a staircase made with elements of the type shown in Figures 1 and 2

En se reportant au dessin, on voit que la structure porteuse 1(1a, 1b), d'un escalier 2(2a, 2b), est formée d'éléments superposés 3(3a, 3b) et pourvus de plateaux 4 en vue de former les marches 5 de cet escalier 2.Referring to the drawing, it is seen that the supporting structure 1 (1a, 1b), a staircase 2 (2a, 2b) is formed from superimposed elements 3 (3a, 3b) and filled trays 4 in order to form the steps 5 of this staircase 2.

L'element 3(3a, 3b) a de préférence une section horizontale circulaire.Element 3 (3 a , 3 b ) preferably has a circular horizontal section.

Il comprend une ossature 10(10a, 10b) et deux pièces d'appui extrêmes 6, 7 parallèles entre elles dont les faces opposées 11, i2 présentent des moyens complémentaires 14, 15 d'assemblage répartis sur des cercles 13 de même diamètre pour que l'assemblage des éléments 3(3a, 3b) entre eux se fasse par superposition exacte des cercles 13 des pièces d'appui 6,' 7 juxtaposées quelle que soit leur orientation réciproque et dont les faces 8, 9 en vis à vis sont donc réliées entre elles au moyen de l'ossature 10(10a, 10b).It comprises a framework 10 (10 a , 10 b ) and two end support pieces 6, 7 which are parallel to each other, the opposite faces 11, i2 of which have complementary means 14, 15 for assembly distributed over circles 13 of the same diameter. so that the elements 3 (3 a , 3 b ) are assembled together by exact superimposition of the circles 13 of the support pieces 6, ' 7 juxtaposed whatever their mutual orientation and whose faces 8, 9 are facing screws are therefore connected to each other by means of the framework 10 (10a, 10b ).

De préférence, les moyens complémentaires 14, 15 d'assemblage sont constitués par des perçages 21, traversant de part en part au moins l'une des pièces 6, 7 et recevant des organes de liaison tels des vis, des boulons ou des goujons.Preferably, the complementary assembly means 14, 15 are formed by holes 21, passing right through at least one of the parts 6, 7 and receiving connecting members such as screws, bolts or studs.

Selon une caractéristique essentielle de l'invention, c'est dans les plans de chacune des extrémités de son ossature que chaque élément présente ses deux pièces d'appui, lesquelles pièces viennent latéralement en saillie vers l'extérieur de l'ossature et réalisent ainsi des brides 6, 7 parallèles entre elles dont l'une au moins concourt à la réalisation d'un plateau de marche. A cet effet, l'ossature est de section horizontale externe plus faible que celle non seulement des brides mais aussi que celle délimitée par les cercles 13 précités sur lesquels les moyens complémentaires 14, 15 des moyens d'assemblage sont avantageusement répartis de même manière.According to an essential characteristic of the invention, it is in the planes of each of the ends of its framework that each element has its two support parts, which parts project laterally projecting towards the outside of the framework and thus achieve flanges 6, 7 parallel to each other, at least one of which contributes to the production of a step plate. For this purpose, the framework is of smaller external horizontal section than that not only of the flanges but also that that delimited by the aforementioned circles 13 on which the complementary means 14, 15 of the assembly means are advantageously distributed in the same way.

L'ossature peut être constituée par plusieurs montants 35 de faible section de manière à dégager les brides d'appui 6, 7 (figure 6), mais de préférence, elle est constituée d'une portion de cylindre 25 de diamètre inférieur à celui du dit cercle 13.The frame can be constituted by several uprights 35 of small section so as to release the support flanges 6, 7 (FIG. 6), but preferably, it consists of a portion of cylinder 25 of diameter smaller than that of the says circle 13.

Avantageusement, l'ossature est coaxiale au dit cercle 13. De plus, le cylindre 25 sera de préférence formé par un tube et les brides d'appui 6, 7 comporteront des ouvertures 26 en regard de 1a cavité interne du tronçon tubulaire, ce qui permettra alors d'y faire passer diverses canalisations et/ou cables.Advantageously, the framework is coaxial with said circle 13. In addition, the cylinder 25 will preferably be formed by a tube and the support flanges 6, 7 will have openings 26 facing the internal cavity of the tubular section, which will then allow the passage of various pipes and / or cables.

Les brides d'appui 6, 7 ont au moins leurs faces opposées 11, 12 qui sont de préférence planes mais, dans une variante de réalisation (figure 6), il peut s'agir de structures en profilés telles des simples cerceaux 17, 18, situés dans des plans parallèles.The support flanges 6, 7 have at least their opposite faces 11, 12 which are preferably flat but, in an alternative embodiment (FIG. 6), they may be structures in sections such as simple hoops 17, 18 , located in parallel planes.

Dans ce cas, les moyens complémentaires 14, 15 d'assemblage peuvent comporter un cerceau en profilé ouvert 17 pour venir coiffer celui de l'autre cerceau 18 pour assurer un rigoureux positionnement.In this case, the complementary assembly means 14, 15 may include an open profile hoop 17 to come over that of the other hoop 18 to ensure rigorous positioning.

Les moyens complémentaires d'assemblage peuvent dans ce cas être réalisés sous la forme de brides et/ou de colliers.The complementary assembly means can in this case be produced in the form of flanges and / or collars.

Qu'elle soit formée d'un seul tube 25 ou plusieurs montants 35, l'ossature 10(10a, lOb) de liaison entre les pièces d'appui 6, 7 d'un même élément 3(3 a 3b), a son axe fictif 23 passant par les centres des cercles 13 qui forment, par rapport au plan des brides, un angle correspondant sensiblement à la pente donnée à l'escalier.Whether formed by a single tube 25 or several uprights 35, the framework 10 (10 a , 10 b ) connecting between the supporting parts 6, 7 of the same element 3 (3 a 3 b ) , has its fictitious axis 23 passing through the centers of the circles 13 which form, with respect to the plane of the flanges, an angle corresponding substantially to the slope given to the staircase.

Dans le cas d'un escalier en colimaçon 2 a tournant donc autour d'un axe vertical, l'axe fictif 23a passant par les centres des cercles 13 est alors perpendiculaire au plan contenant les cercles.In the case of a spiral staircase 2 therefore rotating around a vertical axis, the imaginary axis 23 a passing through the centers of the circles 13 is then perpendicular to the plane containing the circles.

Dans le cas d'un escalier dit droit et/ou tournant en avançant l'ossature 10b a son axe fictif 23b passant par les centres des cercles 13 qui forment alors avec le plan des brides un angle différent de quatre vingt dix degrés puisque de valeur correspondant à la pente donnée à l'escalier.In the case of a staircase said right and / or turning by advancing the frame 10 b has its notional axis 23 b passing through the centers of circles 13 which then form with the flange plane an angle different from ninety degrees as of value corresponding to the slope given to the staircase.

Afin de concourir à la réalisation d'une marche, l'une des brides d'appui de l'élément est étendue jusqu'à acquérir une forme et des dimensions la rendant apte à former directement le plateau 4 d'une marche 5 d'escalier.In order to contribute to the realization of a step, one of the support flanges of the element is extended until acquiring a shape and dimensions making it suitable for directly forming the plate 4 of a step 5 of staircase.

Dans une variante de réalisation, on rapporte un plateau 4 soit entre les deux brides d'appui juxtaposées, soit on l'applique au dessus ou au dessous de l'ensemble de ces deux brides -d'appui juxtaposées, lequel plateau est alors pourvu de parties coopérant avec les brides et/ou les moyens complémentaires d'assemblage de celles-ci pour que,grâce au concours ainsi apporté par les brides, le plateau soit lui-même fixé.In an alternative embodiment, a plate 4 is added either between the two juxtaposed support flanges, or it is applied above or below all of these two flanges - juxtaposed support flanges, which plate is then provided of parts cooperating with the flanges and / or the complementary means of assembling them so that, thanks to the assistance thus provided by the flanges, the plate is itself fixed.

Dans tous les cas, le plateau ne nécessite pour sa Flxation aucun autre élément que ceux déjà prévus pour l'assemblage des éléments entre eux.In all cases, the plate does not require any other element for its fixing than those already provided for assembling the elements together.

Dans une variante de réalisation, grâce aux brides externes réalisant entre elles des chapes, les brides concourent encore à la réalisation de la marche par un meilleur soutien du plateau 4 tel le plateau d'une marche d'un escalier en colimaçon 2 a au moyen d'une marche ou d'une ossature 27 de soutien du plateau de cette marche qui présente au moins une paire d'organes opposés 32, 33 coopérant avec des moyens complémentaires d'assemblage en vis à vis des deux pièces d'appui 6, 7 d'un même élément 3 a tel, par exemple, des tourillons 32, 33 traversant des perçages 21 et utilisant donc également les mêmes moyens d'assemblage que ceux utilisés pour l'assemblage des éléments entre eux.In an alternative embodiment, thanks to the external flanges making between them yokes, the flanges also contribute to the achievement of the step by better support of the plate 4 such as the plate of a step of a spiral staircase 2a by means a step or a frame 27 for supporting the platform of this step which has at least one pair of opposite members 32, 33 cooperating with complementary assembly means opposite the two support pieces 6, 7 of the same element 3 has such, for example, pins 32, 33 passing through bores 21 and therefore also using the same assembly means as those used for assembling the elements together.

De préférence, cette marche ou ossature de soutien comprendra au moins deux paires d'organes opposés afin de définir exactement sa position par rapport à l'élément.Preferably, this step or supporting framework will include at least two pairs of opposite members in order to exactly define its position relative to the element.

Certains des éléments et notamment les éléments extrêmes 31 de l'escalier pourront porter une bride présentant un rabat 29 perpendiculaire au plan de la bride d'appui en vue de réaliser une butée reprenant les efforts horizontaux de l'escalier. L'escalier réalisé avec ces éléments peut avantageusement (comme représenté figure 7), comporter alternativement des éléments dont l'axe fictif de l'ossature est perpendiculaire au plan des brides et des éléments dont l'axe fictif est incliné par rapport à ces plans des brides d'un angle différent de quatre vingt dix degrés, lequel escalier peut en outre tourner à partir de toute marche dans un sens ou dans l'autre pour s'adapter à chaque cas particulier rencontré dans la configuration des accès aux différents paliers d'une construction à équiper du dit escalier.Some of the elements and in particular the extreme elements 31 of the staircase may carry a flange having a flap 29 perpendicular to the plane of the support flange in order to produce a stop taking up the horizontal forces of the staircase. The staircase produced with these elements can advantageously (as shown in FIG. 7), alternately comprise elements whose fictitious axis of the framework is perpendicular to the plane of the flanges and elements whose fictitious axis is inclined relative to these planes flanges of an angle different from ninety degrees, which staircase can also turn from any step in one direction or the other to adapt to each particular case encountered in the configuration of accesses to the different landings of 'a building to be fitted with said staircase.
