Description

La présente invention se rapporte à une plateforme modulable.The present invention relates to a modular platform.

Dans le domaine de la construction, certains corps de métier doivent travailler en hauteur. C'est notamment le cas des plaquistes.In the field of construction, some tradespeople have to work at height. This is particularly the case for plasterers.

A cet effet, un plaquiste utilise des échafaudages comprenant un plancher supporté par des montants et équipé de rambardes ou garde-corps.For this purpose, a plasterer uses scaffolding comprising a floor supported by uprights and equipped with railings or guardrails.

Selon ce type de construction, le plancher a des dimensions fixes qui ne sont généralement pas adaptées au lieu des travaux. Par conséquent, les utilisateurs doivent régulièrement déplacer leurs échafaudages. Habituellement, ils disposent de plusieurs échafaudages accolés les uns aux autres.According to this type of construction, the floor has fixed dimensions which are not generally adapted to the work site. As a result, users have to move their scaffolds regularly. Usually, they have several scaffolds attached to each other.

Ces échafaudages ne donnent pas pleinement satisfaction aux utilisateurs car ils ne sont pas aisément déplaçables, notamment lorsqu'il est nécessaire de déplacer plusieurs échafaudages simultanément.These scaffolds do not give full satisfaction to users because they are not easily movable, especially when it is necessary to move several scaffolds simultaneously.

Le document AU503902 décrit des modules comportant chacun un plancher avec à chaque extrémité des embouts avec des orifices. Ces orifices permettent de recevoir un crochet en forme de S permettant de relier deux modules pour former une plateforme. Ces crochets en S ont une section ronde. En complément, les embouts comprennent des échancrures en demi-cercle permettant de loger la partie centrale des crochets.The document AU503902 describes modules each having a floor with at each end of the tips with orifices. These orifices make it possible to receive an S-shaped hook making it possible to connect two modules to form a platform. These S-hooks have a round section. In addition, the endpieces comprise notches in a semicircle for accommodating the central portion of the hooks.

Ce mode de réalisation n'est pas satisfaisant car les modules peuvent se translater l'un par rapport à l'autre même lorsqu'ils sont reliés par un crochet. Aussi, la présente invention vie à pallier aux inconvénients de l'art antérieur, en proposant une plateforme modulable sûre, pratique à utiliser et aisément déplaçable.This embodiment is not satisfactory because the modules can translate relative to each other even when they are connected by a hook. Also, the present invention lives to overcome the disadvantages of the prior art, by providing a safe modular platform, convenient to use and easily movable.

A cet effet, l'invention a pour objet une plateforme modulable comprenant au moins deux modules comportant chacun un plancher avec des chants longitudinaux et des chants transversaux et deux supports ainsi que deux crochets de liaison assurant la liaison entre deux modules adjacents, un crochet de liaison ayant une forme de S et comprenant une partie centrale, au niveau d'une première extrémité de ladite partie centrale un axe sensiblement parallèle à la partie centrale orienté vers une seconde extrémité de ladite partie centrale susceptible de coopérer avec un orifice prévu au niveau de la surface supérieure du plancher d'un module, et d'autre part, au niveau de la seconde extrémité de ladite partie centrale un axe sensiblement parallèle à la partie centrale orienté vers la première extrémité de ladite partie centrale susceptible de coopérer avec un tube creux solidaire du plancher d'un module dont la section est adaptée à celle de l'axe au niveau de seconde extrémité, où la partie centrale de chaque crochet de liaison est plane sous forme d'une plaque et prolongée à une première extrémité par une première aile pliée à 90° selon une première direction et à une seconde extrémité par une seconde aile pliée à 90° selon une seconde direction opposée à la première direction.To this end, the subject of the invention is a modular platform comprising at least two modules each comprising a floor with longitudinal edges and transverse edges and two supports and two connecting hooks providing the connection between two adjacent modules, a hook of linkage having an S shape and comprising a central portion, at a first end of said central portion an axis substantially parallel to the central portion facing a second end of said central portion engageable with an orifice provided at the level of the upper surface of the floor of a module, and secondly, at the second end of said central portion an axis substantially parallel to the central portion facing the first end of said central portion capable of cooperating with a hollow tube integral with the floor of a module whose section is adapted to that of the axis at the level of second extr emitted, wherein the central portion of each connecting hook is flat in the form of a plate and extended at a first end by a first wing bent at 90 ° in a first direction and at a second end by a second wing bent at 90 ° in a second direction opposite to the first direction.

  • the Figure 11B is a perspective view illustrating another variant of a hook for assembling two modules.

Sur la figure 1, on a représenté un module 10 d'un premier type comprenant un plancher 12 et deux supports 14.On the figure 1 , there is shown a module 10 of a first type comprising a floor 12 and two supports 14.

Le plancher 12 a une forme rectangulaire. A titre indicatif, le plancher a une longueur de l'ordre de 2 m et une largeur de l'ordre de 0,8 m.The floor 12 has a rectangular shape. As an indication, the floor has a length of the order of 2 m and a width of about 0.8 m.

Pour la suite de la description, on entend par direction longitudinale, la direction qui correspond à la longueur du plancher alors que la direction transversale correspond à la largeur.For the remainder of the description, longitudinal direction means the direction corresponding to the length of the floor while the transverse direction corresponds to the width.

Selon un mode de réalisation, le plancher 12 est réalisé à partir d'une tôle dont les bords sont pliés à 90° de manière à former des chants longitudinaux 16 et des chants transversaux 18.According to one embodiment, the floor 12 is made from a sheet whose edges are bent at 90 ° so as to form longitudinal edges 16 and transverse edges 18.

Ainsi, le plancher et les chants transversaux et longitudinaux forment une cavité dans laquelle peuvent être disposés les supports 14 rabattus, comme cela sera expliqué ultérieurement. Lorsque les supports 14 sont rabattus, le module 10 a une forme parallélépipédique de manière à ce que les modules puissent être aisément empilés les uns sur les autres.Thus, the floor and the transverse and longitudinal edges form a cavity in which can be arranged the supports 14 folded, as will be explained later. When the supports 14 are folded down, the module 10 has a parallelepipedal shape so that the modules can be easily stacked on each other.

Selon un mode de réalisation, chaque support 14 comprend deux montants 20 reliés par deux traverses 22, chacun desdits montants 20 ayant une première extrémité pivotante par rapport à une platine 24 solidaire du plancher selon un axe de pivotement 25 orienté selon la direction transversale.According to one embodiment, each support 14 comprises two uprights 20 connected by two crosspieces 22, each of said uprights 20 having a first pivoting end relative to a plate 24 secured to the floor according to a pivot axis 25 oriented in the transverse direction.

De préférence, les montants sont réglables en longueur. Ainsi, chaque montant comprend deux tubes qui coulissent l'un dans l'autre, le premier étant pivotant par rapport à la platine, le second coulissant dans le premier et comprenant au niveau de son extrémité sortante une chape 26 supportant une roulette 28. Avantageusement, la roulette 28 est orientable et peut pivoter autour d'un axe parallèle à la direction du montant comme matérialisé par la double flèche 30. Pour obtenir le réglage en longueur du montant, le premier tube comprend un seul trou traversant orienté selon la direction transversale, le second tube comprenant une succession de trous adaptés pour coopérer avec celui du premier tube. En complément, une goupille prévue pour se loger dans le trou du premier tube et l'un des trous du second tube permet d'empêcher le coulissement du second tube dans le premier tube et ainsi de régler la longueur du montant.Preferably, the uprights are adjustable in length. Thus, each upright comprises two tubes which slide one inside the other, the first being pivotable relative to the plate, the second sliding in the first and comprising at its outgoing end a yoke 26 supporting a wheel 28. Advantageously , the wheel 28 is orientable and can pivot about an axis parallel to the direction of the amount as shown by the double arrow 30. To obtain the length adjustment of the amount, the first tube comprises a single through hole oriented in the transverse direction , the second tube comprising a succession of holes adapted to cooperate with that of the first tube. In addition, a pin adapted to be housed in the hole of the first tube and one of the holes of the second tube makes it possible to prevent the second tube from sliding in the first tube and thus to adjust the length of the upright.

De préférence, les tubes ont des sections carrées.Preferably, the tubes have square sections.

Selon un mode de réalisation, une platine 24 comprend un tube creux 32 avec une section carrée, orienté perpendiculairement au plancher 12, ainsi que deux ailes 34 de part et d'autre dudit tube creux 32 pour assurer sa liaison avec un chant longitudinal 16 à proximité d'un chant transversal 18. La liaison entre la platine 24 et le chant longitudinal 16 est assurée par tous moyens appropriés, par exemple par rivetage (quatre rivets selon l'exemple illustré).According to one embodiment, a plate 24 comprises a hollow tube 32 with a square section, oriented perpendicularly to the floor 12, and two wings 34 on either side of said hollow tube 32 to ensure its connection with a longitudinal edge 16 to close to a transverse edge 18. The connection between the plate 24 and the longitudinal edge 16 is provided by any appropriate means, for example by riveting (four rivets according to the illustrated example).

Une découpe 36 est réalisée au niveau du plancher 12 de manière à rendre accessible le tube creux 32 de la platine depuis le dessus du plancher comme illustré sur la figure 3.A cutout 36 is made at the floor 12 so as to make the hollow tube 32 of the plate accessible from the top of the floor as shown in FIG. figure 3 .

Pour assurer la liaison pivotante entre un montant et la platine correspondante, on peut prévoir une tige ou un tube assurant la fonction d'axe de rotation. Comme illustré sur la figure 1, chaque module 10 du premier type comprend deux supports, pivotant chacun selon un axe de rotation transversal disposé à proximité d'un chant transversal.To ensure the pivotal connection between an upright and the corresponding plate, there can be provided a rod or a tube providing the rotational axis function. As illustrated on the figure 1 each module 10 of the first type comprises two supports, each pivoting about a transverse axis of rotation disposed near a transverse edge.

Chaque support peut occuper deux états, un premier état déployé, comme illustré à gauche de la figure 1, dans lequel le support est disposé à 90° par rapport au plancher, et un second état rabattu, comme illustré à droite de la figure 1, dans lequel le support est disposé parallèlement au plancher.Each support can occupy two states, a first deployed state, as shown to the left of the figure 1 , in which the support is disposed at 90 ° to the floor, and a second folded state, as shown to the right of the figure 1 in which the support is arranged parallel to the floor.

Chaque support 14 dispose d'un jambage 38 pour le maintenir à l'état déployé.Each support 14 has a leg 38 to keep it in the deployed state.

Selon un mode de réalisation, un jambage 38 comprend un premier fourreau 40 qui peut pivoter sur une traverse 22 du support correspondant, notamment la traverse la plus éloignée de l'axe de pivotement du support, une tige 42 s'étendant selon la direction longitudinale et dont une première extrémité est liée au premier fourreau 40, un second fourreau 44 dans lequel peut coulisser la tige 42, un troisième fourreau 46 solidaire du second fourreau 44 apte à pivoter sur un axe 48 s'étendant selon la direction transversale et dont les extrémités sont solidaires des chants longitudinaux du plancher.According to one embodiment, a leg 38 comprises a first sleeve 40 which can pivot on a crosspiece 22 of the corresponding support, in particular the crosspiece farthest from the axis of pivoting of the support, a rod 42 extending in the longitudinal direction and a first end of which is connected to the first sleeve 40, a second sleeve 44 into which the rod 42 can slide, a third sleeve 46 secured to the second sleeve 44 adapted to pivot on an axis 48 extending in the transverse direction and whose ends are integral with the longitudinal edges of the floor.

Comme pour les montants, une goupille est prévue pour limiter le mouvement de coulissement de la tige 42 dans le second fourreau 44 et maintenir ainsi le support à l'état déployé.As for the amounts, a pin is provided to limit the sliding movement of the rod 42 in the second sleeve 44 and thus maintain the support in the deployed state.

Avantageusement, le même axe 48 est utilisé pour les deux ensembles jambage/support d'un même module 10.Advantageously, the same axis 48 is used for the two jamb / support assemblies of the same module 10.

D'autres modes de réalisation pourraient être envisagés pour les supports et les jambages.Other embodiments could be envisaged for the supports and jambs.

Sur la figure 2, on a représenté un module 50 d'un second type. Contrairement à un module 10 du premier type, il ne comprend ni support, ni jambage. Il comprend uniquement un plancher 12 et des platines 24 avec chacune un tube creux 32 accessible depuis le dessus du plancher grâce à une découpe 36.On the figure 2 , there is shown a module 50 of a second type. Unlike a module 10 of the first type, it does not include support or jamb. It comprises only a floor 12 and plates 24 each with a hollow tube 32 accessible from the top of the floor through a cutout 36.

Les modules 50 du second type ont des dimensions analogues aux modules 10 du premier type.The modules 50 of the second type have dimensions similar to the modules 10 of the first type.

Pour obtenir une plateforme selon l'invention, on peut utiliser un ou plusieurs modules 10 du premier type accolés les uns aux autres.To obtain a platform according to the invention, one or more modules 10 of the first type can be used next to one another.

De préférence, on relie deux modules 10 du premier type grâce à un module 50 du second type.Preferably, two modules 10 of the first type are connected by means of a module 50 of the second type.

Les éléments étant liés les uns aux autres, on peut déplacer l'ensemble des modules liés en agissant sur un seul module.The elements being linked to each other, we can move all the linked modules by acting on a single module.

A cet effet, la plateforme comprend des crochets de liaison 52 illustrés sur les figures 5, 6, 11A et 11B.For this purpose, the platform includes connecting hooks 52 illustrated on the Figures 5, 6 , 11A and 11B .

Comme illustré sur la figure 5, un crochet de liaison 52 selon l'invention comprend une platine en forme de S avec une partie centrale 54 plane sous forme d'une plaque et prolongée à une première extrémité par une première aile 56 pliée à 90° selon une première direction et à une seconde extrémité par une seconde aile 58 pliée à 90° selon une seconde direction opposée à la première direction. Le fait de prévoir une partie centrale 54 plane sous forme d'une plaque permet de limiter les mouvements relatifs entre modules lorsqu'ils sont assemblés. Optionnel, le fait de prévoir de part et d'autre de la partie centrale des ailes égales planes sous forme de plaque assure une meilleure stabilité.As illustrated on the figure 5 a connecting hook 52 according to the invention comprises an S-shaped plate with a flat central portion 54 in the form of a plate and extended at a first end by a first flange 56 bent at 90 ° in a first direction and at a second end by a second wing 58 bent at 90 ° in a second direction opposite to the first direction. Providing a flat central portion 54 in the form of a plate makes it possible to limit the relative movements between modules when they are assembled. Optionally, the fact of providing on both sides of the central portion of flat even wings in the form of a plate provides better stability.

Selon un premier mode de réalisation illustré sur la figure 5, pour assurer la liaison entre deux modules, le crochet 52 comprend d'une part au niveau de la première aile 56 un axe 60 sensiblement parallèle à la partie centrale 54 orienté vers la seconde extrémité de ladite partie centrale 54 susceptible de coopérer avec un orifice 62 prévu au niveau de la surface supérieure du plancher d'un module 10 du premier type, de préférence à équidistance des chants, et d'autre part, au niveau de la seconde aile 58 un tube 64 sensiblement parallèle à la partie centrale 54 orienté vers la première extrémité de ladite partie centrale 54 susceptible de coopérer avec un tube creux 66 dont la section est adaptée à celle du tube 64 afin que ce dernier coulisse dans ledit tube creux 66 quasiment sans jeu. De préférence, le tube 64 a une section carrée.According to a first embodiment illustrated on the figure 5 , to ensure the connection between two modules, the hook 52 comprises firstly at the first flange 56 an axis 60 substantially parallel to the central portion 54 facing the second end of said central portion 54 engageable with an orifice 62 provided at the level of the upper surface of the floor of a module 10 of the first type, preferably to equidistance of the edges, and secondly, at the second flange 58 a tube 64 substantially parallel to the central portion 54 facing the first end of said central portion 54 engageable with a hollow tube 66 whose section is adapted to that of the tube 64 so that the latter slides in said hollow tube 66 virtually free play. Preferably, the tube 64 has a square section.

Selon la variante illustrée sur la figure 4, le tube 64 et l'axe 60 sont disposés dans un plan perpendiculaire au plan de la partie centrale 54.According to the variant illustrated on the figure 4 the tube 64 and the axis 60 are arranged in a plane perpendicular to the plane of the central portion 54.

Selon la variante illustrée sur la figure 4, le tube creux 66 est disposé à équidistance du chant longitudinal et du chant transversal et solidarisé à une platine 24.According to the variant illustrated on the figure 4 , the hollow tube 66 is disposed equidistant from the longitudinal edge and the transverse edge and secured to a plate 24.

Pour obtenir un assemblage sûr, la distance entre le tube 64 et la partie centrale 54 notée E sur la figure 5 est sensiblement égale à la distance séparant la face extérieure du chant longitudinal ou du chant transversal et la face intérieure du tube creux 66. De la même manière, la distance entre l'axe 60 et la partie centrale 54, notée E1 sur la figure 5 est sensiblement égale à la distance séparant l'axe de l'orifice 62 du chant longitudinal et du chant transversal.To obtain a secure assembly, the distance between the tube 64 and the central portion 54 noted E on the figure 5 is substantially equal to the distance separating the outer face of the longitudinal song or the transverse edge and the inner face of the hollow tube 66. In the same manner, the distance between the axis 60 and the central portion 54, noted E1 on the figure 5 is substantially equal to the distance separating the axis of the orifice 62 from the longitudinal edge and the transverse edge.

En complément, la longueur de la partie centrale 54 correspond sensiblement à la hauteur d'un chant.In addition, the length of the central portion 54 substantially corresponds to the height of a song.

De préférence, un tube creux 66 est prévu au niveau de chaque angle d'un module 50 du second type.Preferably, a hollow tube 66 is provided at each angle of a module 50 of the second type.

Un orifice 62 est prévu au niveau de chaque angle d'un module 10 du premier type. D'autres orifices 62 peuvent être prévus entre ceux ménagés au niveau des angles selon la direction longitudinale pour associer un module 10 et un module 50 en L ou en T.An orifice 62 is provided at each angle of a module 10 of the first type. Other orifices 62 may be provided between those formed at the angles in the longitudinal direction to associate a module 10 and a module 50 L or T.

Pour assurer la liaison entre un module 10 du premier type et un module 50 du second type, on utilise deux crochets 52. Dans un premier temps, les tubes 64 des deux crochets sont insérés dans les tubes en creux 66 du second module puis les axes 60 des crochets 52 sont insérés dans les orifices 62 du premier module 10.To ensure the connection between a module 10 of the first type and a module 50 of the second type, two hooks 52 are used. In a first step, the tubes 64 of the two hooks are inserted into the hollow tubes 66 of the second module and then the axes 60 of the hooks 52 are inserted into the orifices 62 of the first module 10.

Des crochets de liaison 52 peuvent être utilisés pour assurer la liaison entre deux modules 10 du premier type. Dans ce cas, au moins l'un des deux modules 10 comprend des tubes creux 66 au niveau des platines 24.Link hooks 52 may be used to provide the connection between two modules 10 of the first type. In this case, at least one of the two modules 10 comprises hollow tubes 66 at the level of the plates 24.

Une goupille ou tout autre élément analogue peut être utilisée pour assurer une liaison entre le crochet 52 et le tube creux 66.A pin or the like may be used to provide a connection between the hook 52 and the hollow tube 66.

Selon l'invention, on note que les crochets 52 sont disposés entre les modules et qu'aucun élément de liaison ne vient en saillie par rapport aux modules.According to the invention, it is noted that the hooks 52 are arranged between the modules and no connecting element protrudes from the modules.

Selon une autre variante illustrée sur la figure 10, le tube creux 66 peut être fixé (par soudage par exemple) à la platine 24 au niveau de la face opposée à celle plaquée contre un chant longitudinal. Selon cette variante, seuls les modules du second type comprennent un tube creux 66.According to another variant illustrated on the figure 10 , the hollow tube 66 may be fixed (by welding for example) to the plate 24 at the opposite side to that pressed against a longitudinal edge. According to this variant, only the modules of the second type comprise a hollow tube 66.

Dans ce cas, le tube 64 est déporté par rapport à l'axe 60 comme illustré sur les figures 11A et 11B afin que l'orifice 62 apte à recevoir l'axe 60 soit décalé par rapport au tube creux 32 et que l'aile 58 n'obture pas le tube creux 32.In this case, the tube 64 is offset with respect to the axis 60 as illustrated in FIGS. Figures 11A and 11B so that the orifice 62 adapted to receive the axis 60 is offset relative to the hollow tube 32 and the wing 58 does not close the hollow tube 32.

Ainsi, le tube 64 peut être décalé d'un premier côté comme illustré sur la figure 11A et d'un autre côté comme illustré sur la figure 11B.Thus, the tube 64 can be shifted by a first side as illustrated on the figure 11A and on the other hand as illustrated on the Figure 11B .

Selon un mode d'assemblage, on utilise pour un module du second type au niveau d'un même chant longitudinal à une première extrémité un crochet 52 illustré sur la figure 11A et à l'autre extrémité un crochet 52 illustré sur la figure 11B de manière à disposer les axes 60 des crochets 52 décalés vers l'intérieur par rapport aux tubes 64 desdits crochets 52.According to one method of assembly, for a module of the second type, at the same end, a hook 52 illustrated in FIG. figure 11A and at the other end a hook 52 illustrated on the Figure 11B so as to have the axes 60 of the hooks 52 offset inwardly relative to the tubes 64 of said hooks 52.

Comme illustré sur les figures 7A à 7C, une plateforme est obtenue à partir d'un assemblage d'un module 50 du second type intercalé entre deux modules 10, 10' du premier type. Selon des configurations plus complexes, un autre module du second type peut être intercalé entre le module 10 ou 10' du premier type et un autre module du premier type.As illustrated on Figures 7A to 7C , a platform is obtained from an assembly of a module 50 of the second type interposed between two modules 10, 10 'of the first type. In more complex configurations, another module of the second type can be inserted between the module 10 or 10 'of the first type and another module of the first type.

Selon un mode d'assemblage illustré sur la figure 7A, les modules 10, 50 et 10' sont disposés bout à bout, les chants transversaux de deux modules adjacents étant plaqués l'un contre l'autre.According to an assembly method illustrated on the Figure 7A , the modules 10, 50 and 10 'are arranged end to end, the transverse edges of two adjacent modules being pressed against each other.

Selon un autre mode d'assemblage illustré sur la figure 7B, les modules 10, 50 et 10' sont disposés les uns contre les autres, les chants longitudinaux de deux modules adjacents étant plaqués l'un contre l'autre.According to another method of assembly illustrated on the Figure 7B , the modules 10, 50 and 10 'are arranged against each other, the longitudinal edges of two adjacent modules being pressed against each other.

Selon un autre mode d'assemblage illustré sur la figure 7C, les modules 10 et 10' sont disposés parallèlement et le module 50 est intercalé entre les modules 10 et 10' et disposé perpendiculairement auxdits modules 10 et 10'.According to another method of assembly illustrated on the Figure 7C , the modules 10 and 10 'are arranged in parallel and the module 50 is interposed between the modules 10 and 10' and arranged perpendicularly to said modules 10 and 10 '.

Bien entendu, l'invention n'est pas limitée à ces modes d'assemblage.Of course, the invention is not limited to these methods of assembly.

Selon une autre caractéristique de l'invention, la plateforme comprend un garde-corps disposé au niveau de la périphérie de ladite plateforme.According to another characteristic of the invention, the platform comprises a railing disposed at the periphery of said platform.

Ce garde-corps comprend des rambardes 68 dont la longueur correspond à la longueur d'un module 10 ou 50. Chaque rambarde 68 comprend d'une part deux montants dont les extrémités inférieures sont susceptibles de s'emmancher dans les tubes creux 32 des platines 24 accessibles depuis le dessus du plancher, et d'autre part, des traverses sensiblement horizontales reliant les deux montants. Le garde corps peut comprendre également des montants isolés ou poteau 70 dont les extrémités inférieures sont susceptibles de s'emmancher dans les tubes creux 32 des platines 24 accessibles depuis le dessus du plancher.This guardrail includes guardrails 68 whose length corresponds to the length of a module 10 or 50. Each guardrail 68 comprises on the one hand two uprights whose lower ends are capable of slipping into the hollow tubes 32 of the decks 24 accessible from the top of the floor, and secondly, substantially horizontal ties connecting the two uprights. The guard can also include insulated posts or posts 70 whose lower ends are able to be inserted into the hollow tubes 32 of the plates 24 accessible from the top of the floor.

Le garde-corps comprend également des portillons 72 comportant deux montants verticaux reliés par des traverses. Chaque portillon 72 peut être relié à une rambarde 68 par des moyens d'articulation autorisant un pivotement selon un axe vertical dudit portillon par rapport à la rambarde 68.The guardrail also includes gates 72 having two vertical uprights connected by sleepers. Each door 72 may be connected to a guardrail 68 by hinge means permitting pivoting along a vertical axis of said door relative to the guardrail 68.

En complément, chaque portillon 72 comprend des moyens pour empêcher son pivotement, par exemple un loquet.In addition, each gate 72 comprises means for preventing its pivoting, for example a latch.

Selon un mode de réalisation, chaque portillon 72 comprend au niveau d'un montant deux paumelles 74, chacune comportant un axe orienté vers le bas, coopérant avec deux fourreaux (ou deux pattes avec chacune un orifice) solidaires d'un montant d'une rambarde 68 de manière à former deux charnières. Chaque portillon 72 comprend au niveau de l'autre montant au moins une paumelle 76, comportant un axe orienté vers le bas et coopérant avec au moins un fourreau (ou au moins une patte avec un orifice) solidaire d'un montant isolé 70 ou d'un montant d'une rambarde 68 de manière à former un loquet. Selon cet agencement, l'axe de la paumelle 76 utilisée comme loquet est plus court que les axes des paumelles 74 utilisées comme charnière. Ainsi, pour ouvrir ou fermer le portillon, l'utilisateur doit légèrement soulever le portillon de manière à engager ou dégager l'axe d'une paumelle 76 du fourreau correspondant. Dans la mesure où les axes des paumelles 74 sont plus longs, le portillon est toujours articulé.According to one embodiment, each door 72 comprises at the level of an amount two hinges 74, each having a downward axis, cooperating with two sleeves (or two legs each with an orifice) integral with the amount of a guardrail 68 so as to form two hinges. Each door 72 comprises at the level of the other upright at least one hinge 76, having a downward axis and cooperating with at least one sheath (or at least one lug with an orifice) secured to an insulated upright 70 or an amount of a guardrail 68 so as to form a latch. According to this arrangement, the axis of the hinge 76 used as a latch is shorter than the axes of the hinges 74 used as hinge. Thus, to open or close the gate, the user must slightly lift the gate so as to engage or disengage the axis of a hinge 76 of the corresponding sheath. Insofar as the axes of the hinges 74 are longer, the door is always hinged.

Selon un mode de réalisation, un montant isolé ou poteau 70 comprend au moins un fourreau pour recevoir un axe d'une paumelle 74 ou 76.According to one embodiment, an insulated post or post 70 comprises at least one sleeve for receiving an axis of a hinge 74 or 76.

Selon un mode de réalisation, une rambarde 68 comprend au niveau de chaque montant deux pattes avec chacune un orifice, une en bas et une en haut, lesdites pattes étant rapportées au niveau de chaque montant à la face opposée à celle liée aux traverses des rambardes.According to one embodiment, a guardrail 68 comprises at the level of each upright two tabs each having an orifice, a bottom and a top, said tabs being attached at the level of each upright to the face opposite to that connected to the rails of the rails. .

Selon un mode de réalisation, chaque montant isolé ou poteau 70 comprend deux pattes avec chacune un orifice, une en bas et une en haut.According to one embodiment, each insulated post or post 70 comprises two tabs each with an orifice, one at the bottom and one at the top.

Selon un mode de réalisation, chaque portillon comprend au niveau d'un premier montant deux paumelles 76 et au niveau de l'autre montant deux paumelles 74.According to one embodiment, each door comprises at the level of a first upright two hinges 76 and at the level of the other upright two hinges 74.
