La présente invention telle que définie par la combinaison de caractéristiques de la revendication 1 , tendant à apporter des améliorations à la demande de brevet FR-A-2 691 489, se différencie de cette technique antérieure par sa possibilité de réglage des hauteurs de marches et ou de son giron et ou de la largeur de chaque marche, ce qui rend cet escalier polyvalent et apte à être implanté dans des espaces à volumes dissemblables.The present invention as defined by the combination of features of claim 1, tending to provide improvements to patent application FR-A-2 691 489, are differentiates from this prior technique by its possibility adjusting the heights of steps and or its lap and or the width of each step, which makes this staircase versatile and able to be installed in spaces with volumes dissimilar.

Ainsi l'installation de l'escalier peut former des hauteurs de marches constantes. Thus the installation of the staircase can form constant step heights.

La plupart des escaliers industriels connus nécessitent un socle de départ d'escalier recoupable en hauteur qui, comparé aux espacements verticaux des autres marches, présente une disparité de hauteur pénalisant la cadence de montée ou de descente de l'utilisateur. Ce socle rend la structure inconfortable et dangereuse du fait de cette disparité de hauteur.Most known industrial stairs require a staircase base that can be cut vertically, compared to the vertical spacings of other steps, presents a disparity in height penalizing the cadence of rise or fall of the user. This base makes the uncomfortable and dangerous structure due to this height disparity.

La demande GB-A-2.114.182 divulgue un escalier en spirale construit par assemblage et comprenant une rampe rigide à laquelle sont fixées des barres métalliques s'étendant vers le bas, en direction des marches.GB-A-2.114.182 discloses a staircase in spiral built by assembly and including a ramp rigid to which metal bars are attached extending downward towards the steps.

Le brevet DE-A-2.619.804 décrit plusieurs configurations d'escaliers préfabriqués conçus pour être fabriqués à l'aide de béton renforcé de fibres de verre. A l'inverse de la présente invention, les différentes configurations décrites ainsi que le type de fabrication de celles-ci ne permettent ni un ajustage de la géométrie d'un type d'éléments de l'escalier préfabriqué, ni un choix de position et d'orientation de certains des éléments de l'escalier entre eux pour aboutir à un réglage possible in situ de la hauteur et du giron des marches, alors que la présente invention permet tout cela.DE-A-2,619,804 describes several configurations prefabricated stairs designed to be manufactured using glass fiber reinforced concrete. Unlike the present invention, the different configurations described as well as the type of manufacture of these do not allow nor an adjustment of the geometry of a type of elements of the prefabricated staircase, nor a choice of position and orientation of some of the elements of the staircase between them to achieve a possible in situ height adjustment and the belly of the stairs, while the present invention allows it all.

Suivant un mode d'exécution particulier, la présente invention est un escalier installé entre deux niveaux de sols comme illustré en figure 1.According to a particular embodiment, the present invention is a staircase installed between two floors as illustrated in figure 1.

Sur cette figure nous voyons un élément raidisseur 1 relié à la pièce verticale 3B faisant fonction de poteaux bas et au poteau haut 3E, ainsi que des pièces verticales 4A, 4A1 traversant des modules périphériques 12 et reliées aux traverses 7, 7a présentant un talon ou cale 6, lesquelles supportent les marches 5, 16.In this figure we see a stiffening element 1 connected to vertical part 3B acting as low poles and to the high post 3E, as well as vertical pieces 4A, 4A1 passing through peripheral modules 12 and connected to sleepers 7, 7a having a heel or wedge 6, which support steps 5, 16.

Il y a trois types de pièces verticales 4A, 4A1, 3B fixées au raidisseur 1, éventuellement de section rectangulaire aux arêtes arrondies. There are three types of vertical pieces 4A, 4A1, 3B fixed to stiffener 1, possibly of section rectangular with rounded edges.

Le bas des pièces verticales 4A, 4A1 est percé de deux fentes verticales 9a, 9b superposées de hauteurs différentes.The bottom of the vertical pieces 4A, 4A1 is pierced with two vertical slots 9a, 9b superimposed of different heights.

La fente 9a placée la plus haute est d'une hauteur supérieure par rapport à la fente 9b.The highest slot 9a is of a height higher than slot 9b.

La pièce verticale 3B est percée dans sa partie inférieure d'une fente 9a haute.The vertical part 3B is pierced in its part bottom of a slot 9a high.

La pièce verticale 4A1 est différente de la pièce verticale 4A par sa longueur légèrement supérieure.The vertical part 4A1 is different from the part vertical 4A by its slightly longer length.

L'entraxe des fentes 9a et 9b étant identique sur l'une et sur l'autre des pièces verticales dont la hauteur est différente.The distance between the slots 9a and 9b being identical on one and on the other vertical pieces whose height is different.

Au niveau de chaque fente 9a et 9b sont prévus, perpendiculairement à leur axes, des perçage 14 superposés et placés de façon à permettre le passage des organes de fixation, éventuellement des tourillons 8.At each slot 9a and 9b are provided, perpendicular to their axes, superimposed holes 14 and placed so as to allow the passage of the organs of fixing, possibly pins 8.

La forme particulière des traverses 7a ou traverses 7 équipées de cales 6, permet de régler le giron et la hauteur de marches.The particular shape of sleepers 7a or sleepers 7 equipped with shims 6, allows to adjust the tread and the height of steps.

Les traverses 7a, 7 s'encastrent dans la fente supérieure 9a des pièces verticales 4A, 4A1 ou dans la fente inférieure 9b de la pièce verticale 3B, comme illustré en figure 2.The crosspieces 7a, 7 fit into the slot upper 9a of the vertical pieces 4A, 4A1 or in the slot lower 9b of the vertical part 3B, as illustrated in figure 2.

La partie inférieure des dites traverses 7a comporte un talon, partie saillante, ou une cale 6 qui prend appui sur la partie inférieure de la fente 9a de chacune des pièces verticales.The lower part of said sleepers 7a has a heel, protruding part, or a wedge 6 which rests on the lower part of the slot 9a of each of the parts vertical.

Les fentes 9b prennent appui chacune sur la partie supérieure de chaque traverse 7, 7a.The slots 9b each bear on the part upper of each crosspiece 7, 7a.

Comme présentées en figure 1 et 3, les marches 5, 16 sont percées à chacune de leurs extrémités de trous 9, 15, éventuellement rectangulaires à angles arrondis, permettant le passage des pièces verticales 3B, 4A, 4A1 qui les transpercent en laissant libre accès aux fentes 9a, 9b.As shown in Figure 1 and 3, steps 5, 16 are drilled at each of their ends with holes 9, 15, possibly rectangular with rounded angles, allowing the passage of the vertical parts 3B, 4A, 4A1 which pierce leaving free access to the slots 9a, 9b.

Les dites fentes sont de forme éventuellement rectangulaire aux angles arrondis.Said slots are possibly shaped rectangular with rounded corners.

La fente 9a est prévue pour accueillir la partie la plus haute de la traverse 7a ou de la traverse 7 équipée de sa cale 6.Slot 9a is designed to accommodate the most high of cross member 7a or cross member 7 fitted with its wedge 6.

La partie la moins haute de la traverse 7, 7a est destinée à être introduite dans la fente 9b comme en figures 1 et 2.The lowest part of the crosspiece 7, 7a is intended to be introduced into the slot 9b as in figures 1 and 2.

Dans chaque marche 5, 16 sont aménagés des trous 9 ou 15 dont la dimension dans le sens du giron est supérieure à la dimension, dans le même sens, des pièces verticales 4A, 4A1 traversant les trous 9, ou 3B traversant les trous 15.In each step 5, 16 are arranged holes 9 or 15 whose dimension in the direction of the lap is greater than the dimension, in the same direction, of the vertical pieces 4A, 4A1 passing through holes 9, or 3B passing through holes 15.

Cette disposition, alliée à la possibilité de faire coulisser les traverses 7, 7a dans les fentes 9a, 9b, permet le réglage des pièces verticales 4A, 4A1, 3B par rapport aux marches 5, 16, aux traverses 7, 7a et aux cales 6.This provision, combined with the possibility of making sliding the crosspieces 7, 7a in the slots 9a, 9b, allows the adjustment of the vertical parts 4A, 4A1, 3B relative to the steps 5, 16, at sleepers 7, 7a and at holds 6.

Cela permet d'obtenir entre autres le réglage du giron des marches.This makes it possible, among other things, to adjust the lap steps.

Il est possible de modifier l'espace horizontal entre les pièces verticales 4A, 4A1 de chacune des marches.It is possible to modify the horizontal space between the vertical pieces 4A, 4A1 of each of the steps.

Des modules périphériques 12, 12A, comportant un trou 9c dans lequel passent des pièces verticales 4A, 4A1, 3B coulissent et viennent se poser sur chacune des marches 5, 16 qu'ils contribuent à immobiliser avec le concours d'organes de fixation traversant les marches 5, 16.Peripheral modules 12, 12A, comprising a hole 9c through which pass vertical pieces 4A, 4A1, 3B slide and come to rest on each of the steps 5, 16 that they help to immobilize with the help of organs fastening through the steps 5, 16.

La géométrie de ces modules périphériques permet de masquer les trous 9, 15 des marches.The geometry of these peripheral modules allows hide the holes 9, 15 of the steps.

Au moins une marche de la présente invention comprend sur sa face supérieure, un système qui la rend partiellement ou totalement antidérapante.At least one step of the present invention comprises on its upper side, a system which makes it partially or completely non-slip.

Le fond de marche présente un relief servant de butée pour empêcher le pied d'aller plus loin.The bottom of the step has a relief serving as a stop to prevent the foot from going further.

D'autres modes d'exécution de cet escalier dont la ligne de foulée peut présenter des courbes et ou des lignes brisées sont possible selon la présente invention.Other modes of execution of this staircase including the line stride may have broken curves and / or lines are possible according to the present invention.
