La présente invention, tendant à apporter des améliorations au brevet N° 92 06170 Publié sous le N° 2691 489, se différencie des techniques antérieures 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, tending to bring improvements to patent N ° 92 06170 Published under N ° 2691 489, differs from previous techniques by its possibility of adjusting the heights of steps and / or its lap and or the width of each step , which makes this staircase versatile and suitable for being installed in spaces with dissimilar volumes.
Ainsi l'installation de l' escalier peut former que des hauteurs de marches constantes. La pluspart des escaliers industriels connus nécessitent un socle de départ d'escalier recoupable en hauteur; qui comparé aux espacement verticaux des autres marches présente une disparité de hauteur pénalisant la cadence de monté ou de descente de l'utilisateur. Ce socle rend la structure inconfortable et dangereuse du fait de cette disparité de hauteur.So the installation of the staircase can only form constant step heights. Most of the known industrial staircases require a staircase that can be cut in height; which compared to the vertical spacing of the other steps presents a disparity in height penalizing the rate of ascent or descent of the user. This base makes the structure uncomfortable and dangerous due to this disparity in height.
Suivant un mode d'exécution particulier, la présente invention, est un escalier installé entre deux niveaux de sols fig 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), (4al) (3B) traversant des modules périphériques (12) et reliées aux traverses présentant un talon (7a) ou cale (6) équipant une traverses (7), lesquelles supportent les marches (5) (16).According to a particular embodiment, the present invention is a staircase installed between two levels of floors fig 1. In this figure we see a stiffening element (1) connected to the vertical part (3B) acting as low posts and at high post (3E), as well as vertical pieces (4a), (4al) (3B) passing through peripheral modules (12) and connected to the crosspieces having a heel (7a) or wedge (6) equipping a crosspiece (7), which support the steps (5) (16).
Il y a trois types de pièces verticales(4A )(4A1) (3B) fixées au raidisseur (1), évc ituellement de section rectangulaires aux arrêtes arrondies:. Le bas des pièces verticales (4 A) ( Al) sont percés de deux fente verticale (9a) (9b) supeφosées de hauteurs différentes. La Fente (9a) la plus haute est de type haute par rapport à la fente (9b) . La pièce verticale (3B) est percée dans sa partie inférieure d'une fente (9a) de type haut.There are three types of vertical parts (4A) (4A1) (3B) fixed to the stiffener (1), possibly of rectangular section with rounded edges :. The bottom of the vertical pieces (4 A) (Al) are pierced with two vertical slits (9a) (9b) supeφosées of different heights. The highest slot (9a) is of high type with respect to the slot (9b). The vertical part (3B) is pierced in its lower part with a slot (9a) of high type.
La pièce verticale (4 Al) est différent de la pièce verticale (4 A) par sa longueur légèrement supérieure. L'entr'axe des fentes (9a) et (9b) étant identique sur l'une et sur l'autre des pièces verticales dont la hauteur est différente. Au niveau de chaque fentes (9a) et (9b) sont prévus peφendiculairement à leur axes, des percements (14) supeφosés et placés de façon à permettre le passage des organes de fixation, éventuellement des tourillons (8)The vertical part (4 Al) is different from the vertical part (4 A) by its slightly longer length. The center distance of the slots (9a) and (9b) being identical on both of the vertical pieces whose height is different. At each slot (9a) and (9b) are provided peφendicular to their axes, holes (14) supeφosés and placed so as to allow the passage of the fixing members, possibly pins (8)
La forme particulière des traverse (7a) ou traverses (7) équipées de cales (6), permettent de régler le giron et la hauteur de marches.The particular shape of the crosspieces (7a) or crosspieces (7) fitted with shims (6), allow the tread and the height of the steps to be adjusted.
Les traverses s'encastrent dans la fente supérieure (9a) fig 2 des pièces verticales (4 A) (4 Al) ou dans la fente inférieur de la pièce verticale (3B).The crossmembers fit into the upper slot (9a) fig 2 of the vertical pieces (4 A) (4 Al) or into the lower slot of the vertical piece (3B).
La partie inférieur des dites traverses (7a) comporte un talon, partie saillante, ou une cale (6) qui prend appui sur la partie inférieure de la fente (9 A) de chacun des pièces verticales. Les fentes (9b) prenant appui chacune sur la partie supérieure de chaque traverse (7) (7a).The lower part of said crosspieces (7a) comprises a heel, projecting part, or a wedge (6) which bears on the lower part of the slot (9 A) of each of the vertical parts. The slots (9b) each bearing on the upper part of each crosspiece (7) (7a).
Les marches (5) et (16) fig 1 et 3, sont percées à chacune de leurs extrémités de trous (9) (15), éventuellement rectangulaires à angles arrondis, permettant le passage des pièces verticales (3B) (4a) (4al) qui les transpercent en laissant libre accès aux fentes(9a) et (9b).The steps (5) and (16) fig 1 and 3, are drilled at each of their ends of holes (9) (15), possibly rectangular with rounded angles, allowing the passage of vertical pieces (3B) (4a) (4al ) which pierce them, leaving free access to the slots (9a) and (9b).
Les dites fentes sont de forme éventuellement rectangulaires aux angles arrondis.Said slots are possibly rectangular in shape with rounded corners.
La fente (9b), est prévue pour accueillir la partie la plus haute de la traverse (7a) ou de la traverse (7) équipée de sa cale (6).La partie la moins haute de la traverse (7) ou (7a) étant destinée à être introduite dans la fente (9b) : fig 1.2.The slot (9b) is intended to accommodate the highest part of the crosspiece (7a) or of the crosspiece (7) equipped with its wedge (6) .The lowest part of the crosspiece (7) or (7a ) being intended to be inserted into the slot (9b): fig 1.2.
Dans chaque marches (5) ou(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). Cette disposition alliée à la possibilité de faire coulisser les traverses (7), (7a) dans les fentes (9a), (9b) permet le réglage des pièces verticales (4 A), (4 Al) ou (3B) par rapport aux marches (5) ou (16), aux traverses (7), (7a) et aux cales (6). Cela permet d'obtenir entre autres le réglage du giron des marches. Il est possible de modifier l'espace horizontal entre les pièces verticale (4 A) et (Al) de chacune des marches.In each step (5) or (16) are provided 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 the holes (9), or (3B) passing through the holes (15). This arrangement combined with the possibility of sliding the crosspieces (7), (7a) in the slots (9a), (9b) allows the adjustment of the vertical pieces (4 A), (4 Al) or (3B) relative to the steps (5) or (16), crosspieces (7), (7a) and wedges (6). This makes it possible, among other things, to adjust the tread of the steps. It is possible to modify the horizontal space between the vertical pieces (4 A) and (Al) of each of the steps.
Des modules périphériques (12) (12 A) comportant un trou (9c) dans lesquels 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). La géométrie de ces modules périphériques permet de masquer les trous (9), (15) des marches. Au moins une marche de la présente invention, comprend sur sa face supérieure, un système qui la rend parciellement ou totalement antidérapante.Peripheral modules (12) (12 A) comprising a hole (9c) through which pass vertical pieces (4A) (4A1) (3B) slide and come to rest on each of the steps (5) (16) which they contribute to be immobilized with the help of fasteners crossing the steps (5) (16). The geometry of these peripheral modules makes it possible to hide the holes (9), (15) of the steps. At least one step of the present invention, comprises on its upper face, a system which makes it partially or totally non-slip.
