The pins include a sliding member i.e. stop interface, on a ladder side.

Description

La présente invention concerne un système d'échelle amovible pour module d'habitation ou de stockage ainsi qu'une échelle adaptée au système. Elle a des applications dans le domaine de la construction ou du stockage modulaire et plus particulièrement pour la mise en oeuvre de modules d'habitation standardisés. Elle est destinée à assurer une certaine sécurité aux opérateurs devant monter le long et sur de tels modules.The present invention relates to a removable ladder system for housing or storage module and a ladder adapted to the system. It has applications in the field of construction or modular storage and more particularly for the implementation of standardized housing modules. It is intended to provide some security for operators to climb along and such modules.

Les modules d'habitation ou de stockage de type « ALGECO » (marque déposée) ou de type containeur normalisé pour transport de marchandises sont d'un usage courant. Le terme habitation couvre toute utilisation aussi bien à titre temporaire (bureau, vestiaire...) qu'à plus long terme (logement...). Les containeurs normalisés pour transport de marchandises sont largement utilisés dans les transports terrestres ou maritimes. Ils sont de forme généralement parallélépipédique et comportent le long de leurs parois, en général le long de montants de bords ou à leurs coins des orifices permettant leur manipulation ou leur arrimage par introduction d'un outil de levage ou d'arrimage. Ces modules peuvent également être empilés les uns sur les autres.The "ALGECO" (registered trademark) type of housing or storage modules or standard container type for the transport of goods are in common use. The term "habitation" covers all uses both temporarily (office, cloakroom ...) and longer term (housing ...). Standard freight containers are widely used in land and sea transport. They are of generally parallelepipedal shape and have along their walls, generally along edge posts or at their corners openings for handling or securing by introduction of a lifting tool or lashing. These modules can also be stacked on top of each other.

Lors de la mise en oeuvre de ces modules, il peut être nécessaire d'accéder à la partie supérieure du ou des modules, par exemple pour procéder à des raccordements électriques ou hydrauliques ou mettre en place des moyens de fixation entre les différents modules. Dans ce cas, l'opérateur doit monter sur le/les modules et il doit utiliser une échelle. Or, pour sa stabilité, une échelle rapportée classique doit avoir une certaine inclinaison et le sol doit être aussi adapté (stable, portant, régulier...). Ceci impose certaines contraintes, notamment disponibilité d'un espace suffisant autour du module, terrain adapté, ou peut conduire à des situations dangereuses si ces contraintes ne sont pas respectées.During the implementation of these modules, it may be necessary to access the upper part of the module or modules, for example to make electrical or hydraulic connections or set up fixing means between the various modules. In this case, the operator must climb onto the module (s) and use a ladder. However, for its stability, a classic reported ladder must have a certain inclination and the floor must also be adapted (stable, carrying, regular ...). This imposes certain constraints, in particular availability of sufficient space around the module, adapted terrain, or can lead to dangerous situations if these constraints are not respected.

Il peut alors être intéressant de disposer d'une échelle qui, tout en étant amovible, soit solidaire du module et n'ait pas besoin de reposer sur le sol et d'être inclinée. En outre, il est également utile que l'opérateur qui utilise une telle échelle puisse le faire dans des conditions de sécurité optimale et, en particulier que l'opérateur soit sécurisé en s'attachant à un rail de l'échelle par l'intermédiaire d'un coulisseau antichute, ce qui n'est pas possible dans le cas de l'utilisation d'une échelle classique. Toutefois, de préférence, cela ne doit pas conduire à des modifications du module et il est donc nécessaire d'utiliser des moyens disponibles sur le module pour une telle mise en oeuvre d'échelle amovible. Dans le cas de la présente invention, ces moyens sont les orifices de passage d'organes de manipulation ou d'arrimage de module que l'on trouve classiquement aux coins des modules ou le long de leurs bords, plus particulièrement les bords verticaux. Dans d'autres cas, on peut-être amené à percer des orifices dans les montants verticaux du module au cas où celui-ci n'en comporterait pas ou que les orifices d'origine ne conviendraient pas. De plus, l'échelle doit assurer une continuité lorsque plusieurs modules sont empilés les uns sur les autres et doit permettre d'assurer une certaine sécurité à l'opérateur lorsqu'il accède à la partie supérieure du module le plus haut.It may be interesting to have a ladder which, while removable, is integral with the module and does not need to rest on the ground and be inclined. Furthermore, it is also useful for the operator who uses such a ladder to be able to do so under optimum safety conditions and, in particular, that the operator is secure by attaching himself to a ladder rail via fall arrest, which is not possible in the case of the use of a conventional ladder. However, preferably, this should not lead to modifications of the module and it is therefore necessary to use the means available on the module for such a removable ladder implementation. In the case of the present invention, these means are the orifices for passage of module handling or securing members that are conventionally found at the corners of the modules or along their edges, more particularly the vertical edges. In other cases, it may be necessary to drill holes in the vertical uprights of the module in case it does not include or that the original openings would not be suitable. In addition, the scale must provide continuity when multiple modules are stacked on top of one another and must to ensure a certain security for the operator when he reaches the top of the highest module.

Le système d'échelle des Figures 1 à 3a, est une version à rail et barreaux simplifiés destinée à faciliter les explications concernant les moyens d'insertion et d'accrochage de l'échelle sur le module.The scale system of Figures 1 to 3a , is a simplified rail and bar version intended to facilitate explanations concerning the means of insertion and attachment of the ladder on the module.

Sur la Figure 1 on a schématisé la mise en place du système d'échelle amovible par la représentation de la relation entre une échelle 4 et un des bords verticaux d'un module 1. Le bord vertical du module est formé d'un montant 2 creux, notamment profilé métallique de section générale en équerre ou carré, comportant des orifices 3 normalement destinés à la manipulation du module par des équipements adaptés et/ou à son arrimage. L'échelle 4 est constituée d'un rail 5 vertical médian sur lequel sont fixés des barreaux 6 et des pions 7 qui sont placés en face des orifices. Dans un premier temps l'échelle est donc disposée verticalement le long du montant de façon à ce que les pions puissent être introduits dans les orifices selon un mouvement schématisé sur la Figure 1 par les flèches étendues le long des axes pion-orifice. Le cartouche en relation avec la Figure 1 permet de mieux visualiser la relation pion 7 - orifice 3 lors de ce premier temps. Dans cet exemple, l'orifice est circulaire ainsi que le pion au moins dans sa partie en relation avec l'orifice.On the Figure 1 the layout of the removable ladder system has been schematized by the representation of the relationship between a scale 4 and one of the vertical edges of a module 1. The vertical edge of the module is formed of a hollow upright 2, in particular profiled metal section generally square or square, having orifices 3 normally intended for handling the module by suitable equipment and / or its stowage. The ladder 4 consists of a median vertical rail 5 on which are fixed bars 6 and pins 7 which are placed in front of the orifices. In a first step the ladder is arranged vertically along the upright so that the pins can be introduced into the orifices in a schematic movement on the Figure 1 by the arrows extended along the pion-orifice axes. The cartridge in relation to the Figure 1 allows to better visualize the relation pion 7 - orifice 3 during this first time. In this example, the orifice is circular and the pin at least in its portion in relation to the orifice.

Sur la Figure 2, dans un deuxième temps, les pions ont été introduits dans leurs orifices respectifs. Sur la Figure 2a on peut voir que le pion comporte une extrémité d'insertion 8 (coté montant et introduit dans ce montant) d'extrémité libre arrondie afin de faciliter son introduction dans l'orifice. Le pion est en butée contre le bord de l'orifice par une butée 10 de dimension transversale empêchant la traversée de l'orifice. On peut noter, d'un coté radial du pion, la présence d'une gorge 9 au niveau de l'interface butée 11 et extrémité d'insertion 8 dont le rôle va être expliqué par la suite. Le pion 7 comporte coté échelle un organe de coulissement 11 permettant de régler la hauteur du pion le long de l'échelle. Un moyen non représenté dans le détail permet de fixer en le bloquant le pion le long du rail une fois la bonne position atteinte. Dans une variante, le pion est fixé une fois pour toute au rail, par exemple par soudure ou sertissage, et il n'y a pas de possibilité de réglage de la hauteur du pion le long du rail.On the Figure 2 in a second step, the pins were introduced into their respective orifices. On the Figure 2a it can be seen that the pin has an insertion end 8 (rising side and introduced into this amount) rounded free end to facilitate its introduction into the hole. The pin is in abutment against the edge of the orifice by a stop 10 of transverse dimension preventing the passage of the orifice. It may be noted, on a radial side of the pin, the presence of a groove 9 at the abutment interface 11 and insertion end 8 whose role will be explained later. The pin 7 has a sliding member 11 on the ladder side to adjust the height of the pin along the scale. A means not shown in detail allows to fix by blocking the pin along the rail once the right position reached. In a variant, the pin is fixed once and for all to the rail, for example by welding or crimping, and there is no possibility of adjusting the height of the pin along the rail.

Sur la Figure 3, dans un troisième temps, l'échelle est accrochée par un léger mouvement vertical vers le bas qui fait que le bord de l'orifice 3 rentre dans la gorge 9 du pion. Une fois cet accrochage réalisé, une traction horizontale de l'échelle ne peut pas la désolidariser du module. On comprend que pour retirer l'échelle du module il est nécessaire d'effectuer les déplacements inverses de ceux précédemment indiqués, c'est-à-dire qu'il est nécessaire d'appliquer un léger mouvement vertical vers le haut puis de tirer horizontalement l'échelle pour que les pions puissent se décrocher et se retirer des orifices. On peut noter que le fait que la gorge ne soit que d'un coté du pion, outre de rendre la mise en oeuvre de l'échelle unidirectionnelle, permet de faciliter le décrochage et démontage de l'échelle car il n'y a pas de risque qu'une gorge haute (non représentée) opposée à celle du bas (représentée) vienne interférer avec l'autre bord (le bord haut) de l'orifice lors du mouvement de l'échelle vers le haut pour décrochage.On the Figure 3 in a third step, the ladder is hung by a slight downward vertical movement which causes the edge of the orifice 3 to enter the groove 9 of the peg. Once this hooking done, a horizontal pull of the scale can not separate it from the module. It is understood that to remove the scale of the module it is necessary to perform the reverse displacements of those previously indicated, that is to say it is necessary to apply a slight upward vertical movement and then pull the ladder horizontally so that the pins can unhook and withdraw from the orifices. It may be noted that the fact that the groove is only one side of the pawn, besides making the implementation of the unidirectional scale, makes it easier to unhook and dismount the scale because there is no risk that a high groove (not shown) opposite that of the bottom (shown) comes to interfere with the other edge (the top edge) of the orifice during movement of the ladder upwards for stall.

De préférence, les dimensions de la gorge par rapport à celle de l'épaisseur du montant sont telles que le jeu est réduit afin que l'échelle ne puisse pas trop bouger lorsqu'elle est soumise à des efforts divers. De plus, ces dimensions sont adaptées au niveau de résistance mécanique souhaité. De même, le diamètre de l'extrémité d'insertion du pion est sensiblement égal au diamètre de l'orifice à un certain jeu près destiné à permettre une insertion relativement aisée du pion dans l'orifice de montant.Preferably, the dimensions of the groove relative to that of the thickness of the upright are such that the clearance is reduced so that the ladder can not move too much when subjected to various stresses. In addition, these dimensions are adapted to the desired level of mechanical strength. Similarly, the diameter of the insertion end of the pin is substantially equal to the diameter of the orifice to a certain clearance to allow a relatively easy insertion of the pin in the stud hole.

Le système d'échelle présenté, bien que simplifié, peut comporter des éléments complémentaires comme des moyens de liaison amovibles entre extrémités correspondantes d'échelles et/ou un prolongateur d'échelle qui vont être présentés à la suite.The scale system presented, although simplified, may include complementary elements such as removable connecting means between corresponding ends of scales and / or a scale extender which will be presented later.

On va maintenant décrire les Figures 4 à 4f concernant un système d'échelle perfectionné dans lequel on met en oeuvre les moyens d'insertion et d'accrochage d'échelle sur module présentés précédemment mais qui ne sont pas représentés en eux-mêmes sur les figures afin de simplifier la description de ce système d'échelle perfectionné.We will now describe the Figures 4 to 4f concerning an improved scale system in which one implements the insertion means and scale-on-module presented above but which are not represented in themselves in the figures to simplify the description of this system of improved scale.

Ce système d'échelle perfectionné permet en particulier l'installation sur son rail d'une fixation coulissante antichute d'une longe de retenue d'un opérateur, l'opérateur étant revêtu d'un harnais de sécurité relié à la longe de retenue. A cette fin, le rail central comporte un profilé en double C, les formes en C étant opposés dos à dos, et le profilé comportant donc des ouvertures le long de sa hauteur sur ses deux faces opposées. Il est ainsi possible d'utiliser un des C du profilé pour le coulissement d'un coulisseau de longe et l'autre pour la fixation des barreaux et des pions 7 et/ou organes de coulissement 11 de pions. On peut en particulier voir cette structure de profilé en double C du rail central 5 sur les Figures 4a, 4b et 4c vues en coupe.This improved scale system allows in particular the installation on its rail of a sliding fastener fall arrest of an operator retaining lanyard, the operator being covered with a safety harness connected to the retaining lanyard. To this end, the central rail comprises a double C profile, the C shapes being opposite back to back, and the profile thus having openings along its height on its two opposite faces. It is thus possible to use one of the C of the profile for sliding a lanyard slide and the other for fixing the bars and pins 7 and / or sliding members 11 pions. This double-C profile structure of the central rail 5 can in particular be seen on the Figures 4a, 4b and 4c sectional views.

L'échelle perfectionnée comporte latéralement deux longerons 19 d'extrémités de barreaux 6 rivetés 15 destinés à la renforcer. Dans une variante, les longerons comporte un moyen permettant la fixation coulissante de la longe. De préférence les extrémités des échelles de chaque module comportent des moyens de liaison amovibles permettant de solidariser ensembles les échelles qui se suivent le long de la hauteur d'un empilement de modules. Ce moyen de liaison amovible est par exemple une patte dépassant l'extrémité supérieure du rail creux et pouvant être introduite dans l'extrémité inférieure du rail creux de l'échelle juste supérieure ou d'un prolongateur d'échelle dans le cas où l'échelle en question correspond au module le plus haut. Dans ce dernier cas, le prolongateur d'échelle ne comporte donc pas de patte à son extrémité inférieure. Dans des variantes, le moyen de liaison amovible entre échelles adjacentes ou prolongateur d'échelle est un système d'accrochage manuel activé ou désactivé par un opérateur lors de sa progression le long des échelles et prolongateur d'échelle. Le verrouillage du système d'accrochage des échelles peut-être automatique.The improved scale comprises laterally two longitudinal members 19 of riveted rods 6 for reinforcing 15. In a variant, the longitudinal members comprise a means allowing the sliding fastening of the lanyard. Preferably the ends of the ladders of each module comprise removable connecting means for joining together the scales that follow along the height of a stack of modules. This detachable connection means is for example a lug protruding from the upper end of the hollow rail and can be introduced into the lower end of the hollow rail of the ladder just above or an extension scale in the case where the scale in question corresponds to the highest module. In the latter case, the ladder extender therefore has no tab at its lower end. In variants, the detachable connecting means between adjacent ladders or ladder extender is a manual snap system activated or deactivated by an operator during its progression along the ladder and extender scale. The locking system ladders can be automatic.

C'est cette dernière modalité qui est présentée en détail sur les Figures 4d, 4e et 4f. Une première extrémité de l'échelle 4 comporte un moyen de liaison amovible d'un premier type, ici pour l'extrémité inférieure un moyen de type femelle 12, et la seconde extrémité de l'échelle comporte un moyen de liaison amovible d'un second type, ici pour l'extrémité supérieure un moyen de type mâle 13. Ces moyens de liaison amovible sont du type à crochetage avec un crochet 14 basculant à moyen de rappel à ressort. Le crochet du moyen mâle 13 est actionné par un doigt 16 du moyen femelle 12.It is this last modality which is presented in detail on the Figures 4d, 4e and 4f . A first end of the ladder 4 comprises a removable connection means of a first type, here for the lower end a female-type means 12, and the second end of the ladder comprises a removable connection means of a second type, here for the upper end means of the male type 13. These removable connection means are of the hook type with a rocking hook 14 with spring biasing means. The hook of the male means 13 is actuated by a finger 16 of the female means 12.

Dans des modalités de réalisation, un moyen 18 de libération de coulisseau de fixation d'antichute représenté Figures 5, 5a et 5b est monté sur l'extrémité libre haute du rail du prolongateur d'échelle ou de l'échelle (de la plus haute échelle d'une succession d'échelles dans le cas où des modules sont empilés). L'échelle ou le prolongateur d'échelle est ainsi équipé à son extrémité supérieure libre d'un moyen 18 d'extrémité de libération de coulisseau de fixation d'antichute permettant, après pivotement dudit moyen, l'extraction du coulisseau de fixation de longe d'un harnais d'un opérateur. L'opérateur revêtu d'un harnais de sécurité fixe sa longe de retenue sur le coulisseau antichute et il ne peut retirer le coulisseau du rail de l'échelle ou prolongateur, par le haut, que lorsque le moyen 18 est pivoté comme représenté sur la Figure 5b. Ce moyen 18 de libération de coulisseau d'antichute comporte deux parties principales qui pivotent l'une par rapport à l'autre, une première pour montage sur le rail de l'échelle ou du prolongateur d'échelle et une seconde pivotante par rapport à la première. Ce pivotement est d'environ 120° entre une position de retrait pour libération du coulisseau et une position opérationnelle empêchant la sortie du coulisseau hors du rail. Deux moyens d'extrémité de libération de coulisseau sont disponibles, un premier type à entrée/sortie pivotante à droite et un second type à entrée/sortie pivotante à gauche.In embodiments, a fall arrest fastener release means 18 shown in FIG. Figures 5, 5a and 5b is mounted on the free end of the rail ladder extender or ladder (the highest scale of a succession of ladders in the case where modules are stacked). The ladder or the ladder extender is thus equipped at its free upper end with a fall arrest fastener release end means 18 allowing, after pivoting of said means, the extraction of the lanyard fixing slide of a harness of an operator. The operator wearing a safety harness secures his retaining lanyard on the fall arrest slider and can only remove the slider from the ladder rail or extension, from above, when the means 18 is pivoted as shown on the Figure 5b . This fall arrest slide release means 18 comprises two main parts that pivot relative to each other, a first one for mounting on the ladder or ladder extender rail and a second pivoting part relative to the other. the first one. This pivoting is approximately 120 ° between a withdrawal position for release of the slide and an operational position preventing the exit of the slide from the rail. Two slider release end means are available, a first right swivel input / output type and a second left swivel input / output type.

Bien entendu la présente invention n'est pas limitée aux modes de réalisation particuliers qui viennent d'être décrits, mais s'étend à toutes variantes et équivalents conformes à son esprit. Ainsi, on comprend bien que l'invention peut être déclinée selon de nombreuses autres possibilités sans pour autant sortir du cadre défini par la description et les revendications. Par exemple, l'échelle peut aussi être utilisée à l'intérieur du module, un trou d'homme étant éventuellement prévu sur la paroi du haut et/ou du bas du module le long de la verticale de l'échelle pour passage de l'opérateur hors du module (trou d'homme ouvert ou à fermeture/ouverture).Naturally, the present invention is not limited to the particular embodiments which have just been described, but extends to all variants and equivalents in accordance with its spirit. Thus, it is clear that the invention can be declined according to many other possibilities without departing from the scope defined by the description and the claims. For example, the ladder can also be used inside the module, a manhole being optionally provided on the wall of the top and / or bottom of the module along the vertical of the ladder for passage of the module. operator outside the module (manhole open or close / open).
