Description

La présente invention concerne de manière générale la protection des personnes travaillant sur les toitures de constructions.The present invention relates generally to the protection of persons working on building roofs.

La réglementation impose de protéger les personnes qui travaillent sur les toitures de constructions. Il existe des équipements de protection collective anti-chute appelés « ring » qui sont formés d'une structure périphérique de type garde-corps destinée à être rapportée sur la toiture d'une construction modulaire. La construction modulaire est appelée usuellement module. Cependant, l'utilisation d'un tel équipement de protection nécessite des opérations de transport et d'installation fastidieuses et coûteuses en temps. En outre, cet équipement de protection étant un équipement amovible, rien ne permet de s'assurer que cet équipement soit réellement installé et utilisé sur la toiture du module.Regulations require the protection of people working on building roofs. There are collective anti-fall protection equipment called "rings" which are formed of a peripheral structure of the guardrail type intended to be attached to the roof of a modular construction. Modular construction is usually called module. However, the use of such protective equipment requires tedious and time-consuming transport and installation operations. In addition, since this protective equipment is a removable device, nothing makes it possible to ensure that this equipment is actually installed and used on the roof of the module.

Il existe aussi des équipements de protection qui comprennent des garde-corps relevables et rabattables mais leur maniement est fastidieux et compliqué en particulier lorsque le module concerné est superposé à un autre module. Afin de former un étage supplémentaire, Il arrive alors qu'un opérateur monte sur la toiture du module du premier étage pour rabattre l'équipement de protection anti-chute de sorte qu'il se retrouve alors en position de travail non sécurisée.There are also protective equipment that include liftable and foldable guardrails but their handling is tedious and complicated especially when the module concerned is superimposed on another module. In order to form an additional stage, it happens that an operator climbs on the roof of the module of the first stage to fold down the fall protection equipment so that it is then in unsafe working position.

CN 202 912 199 U décrit une construction selon le préambule de la revendication 1. CN 202 912 199 U discloses a construction according to the preamble of claim 1.

La présente invention a pour but de proposer une nouvelle construction, de préférence modulaire, comprenant un équipement de protection anti-chute qu'un opérateur peut activer ou désactiver de manière simple et sécurisée.The present invention aims to provide a new construction, preferably modular, including fall protection equipment that an operator can activate or deactivate in a simple and secure manner.

A cet effet, l'invention a pour objet une construction comprenant les caractéristiques de la revendication 1.For this purpose, the subject of the invention is a construction comprising the features of claim 1.

L'équipement de protection anti-chute s'étend dans le périmètre de la toiture, et ladite partie de saisie du lien s'étend en dehors du périmètre de l'équipement de protection anti-chute.The fall protection equipment extends into the perimeter of the roof, and the said gripping portion of the tie extends outside the perimeter of the fall protection equipment.

Ledit lien est lié à l'équipement de protection anti-chute de telle sorte que l'opérateur situé à l'extérieur de la construction n'a qu'à tirer sur l'extrémité libre du lien accessible depuis l'extérieur de la construction, pour commander le passage en position inactive de l'équipement. En particulier, comme détaillé ci-après, la traction sur le système de lien entraine le rabat des garde-corps les uns sur les autres.This link is related to the fall protection equipment so that the operator located outside the building only has to pull the free end of the link accessible from outside the building. , to control the transition to the inactive position of the equipment. In particular, as detailed below, the traction on the link system causes the flap of the railings on top of each other.

Selon l'invention, le lien est un lien souple.According to the invention, the link is a flexible link.

L'opérateur peut ainsi, sans monter sur la toiture, saisir la partie du système de lien qui pend en dehors de la construction, et tirer dessus pour désactiver les moyens d'équipement à l'encontre des moyens de rappel correspondants. Pour activer l'équipement de protection, il suffit à l'opérateur de relâcher la partie de saisie du système de lien pour laisser les moyens de rappel rappeler l'équipement en position active.The operator can thus, without mounting on the roof, enter the part of the link system that hangs outside the construction, and shoot to disable the means of equipment against the corresponding return means. To activate the protection equipment, it is sufficient for the operator to release the input portion of the link system to allow the recall means to recall the equipment in the active position.

Selon une caractéristique avantageuse de l'invention, l'équipement de protection anti-chute comprend, d'une part, deux garde-corps opposés, appelés garde-corps d'extrémité, et, d'autre part, deux autres garde-corps opposés, appelés garde-corps latéraux qui, en configuration active dudit équipement, s'étendent d'un garde corps d'extrémité à l'autre.According to an advantageous characteristic of the invention, the fall protection equipment comprises, on the one hand, two opposite guardrails, called end railings, and, on the other hand, two other guardrails. opposed, called side railings which in active configuration of said equipment, extend from one end guard to the other.

Selon une caractéristique avantageuse de l'invention, le système de lien comprend une partie formant, seule ou en combinaison avec un autre lien, ladite partie de saisie, et, pour chaque garde-corps d'extrémité :

  • une partie, dite partie intérieure, qui s'étend à l'intérieur du périmètre de l'équipement jusqu'à l'un ou chacun des garde-corps d'extrémité, et
  • une partie, dite partie extérieure, liée à la partie intérieure par exemple par un anneau, qui s'étend du côté extérieur d'un garde-corps d'extrémité, tout en étant fixée à un ou chacun desdits garde-corps latéraux.
According to an advantageous characteristic of the invention, the link system comprises a part forming, alone or in combination with another link, said gripping part, and, for each end guard:
  • a portion, said inner portion, which extends within the perimeter of the equipment to one or each of the end railings, and
  • a portion, said outer portion, connected to the inner portion for example by a ring, which extends from the outer side of an end guard, while being attached to one or each of said side rails.

La partie de saisie peut être formée à partir de liens présentant chacun une partie, de préférence une extrémité, s'étendant en dehors de la construction, lesdits liens partant l'un vers un garde-corps corps d'extrémité l'autre vers l'autre garde-corps d'extrémité. La partie de saisie peut aussi être formée à partir d'un seul lien dont une partie, formant partie se saisie, s'étend en dehors de la construction, ledit lien partant vers un garde-corps d'extrémité puis vers le garde-corps d'extrémité opposé pour revenir en dehors de la construction et doublant ainsi ladite partie de saisie.The gripping portion may be formed from links each having a portion, preferably one end, extending outwardly of the construction, said links extending from one to a guard body end body to the other towards the end. other end railing. The gripping portion may also be formed from a single bond, a portion of which, forming a gripping portion, extends outwardly of the construction, said bond extending to an end railing and then to the guardrail opposite end to return outside the construction and thus doubling said gripping portion.

Selon une caractéristique avantageuse de l'invention, les parties de saisie et intérieure du système de lien sont formées par un même lien.According to an advantageous characteristic of the invention, the gripping and inner parts of the link system are formed by the same link.

Dans l'exemple illustré en particulier à la figure 1, on a représenté une construction 1 modulaire qui comprend une toiture 2.In the example illustrated in particular in the figure 1 , there is shown a modular construction 1 which comprises a roof 2.

Dans la suite de la description, la construction modulaire est appelée module. La toiture 2 du module 1 comporte un châssis 20 de toiture et au moins une couverture 21 reposant sur ledit châssis 20. La couverture 21 peut être formée de plusieurs bac-aciers.In the following description, the modular construction is called module. The roof 2 of the module 1 comprises a roof frame 20 and at least one cover 21 resting on said frame 20. The cover 21 may be formed of several steel trays.

Dans l'exemple illustré aux figures, la construction comprend deux faces 82 opposées, appelées faces d'extrémité, reliées entre elles par deux faces 81 opposées, appelées faces latérales.In the example illustrated in the figures, the construction comprises two opposite faces 82, called end faces, interconnected by two opposite faces 81, called side faces.

Dans l'exemple illustré aux figures, lesdites faces latérales s'étendent parallèlement à l'axe longitudinal de la construction et sont encore appelées long-pans. Les deux faces d'extrémité sont encore appelées pignons d'extrémité. Lesdites faces peuvent être fermées ou ouvertes. Dans l'exemple illustré aux figures, les faces sont formées de deux montants, délimitant entre eux une ouverture de passage.In the example illustrated in the figures, said lateral faces extend parallel to the longitudinal axis of the construction and are also called long-sides. Both end faces are still called end gears. Said faces can be closed or open. In the example illustrated in the figures, the faces are formed of two uprights, delimiting between them a passage opening.

La construction comprend aussi un châssis de plancher 10 opposé au châssis 20 de toiture. Les châssis de plancher et de plafond sont reliés l'un à l'autre par lesdites faces murales opposées deux à deux.The construction also includes a floor frame 10 opposite to the roof frame 20. The floor and ceiling frames are connected to each other by said opposite wall faces in pairs.

Le châssis 20 de toiture est formé d'un cadre de profilés et de pannes s'étendant entre deux profilés 201 opposés dudit cadre pour recevoir un élément 21 de couverture, ici un bac-acier. Dans l'exemple illustré aux figures, lesdits deux profilés 201 opposés sont des longerons et les pannes s'étendent parallèlement aux traverses (non représentées) du cadre du châssis 20 de toiture. Les profilés 202 qui s'étendent le long des faces d'extrémité forment les traverses dudit cadre de châssis 20.The roof frame 20 is formed of a frame of profiles and purlins extending between two opposite sections 201 of said frame to receive a cover element 21, here a steel tank. In the example illustrated in the figures, said two opposite sections 201 are longitudinal members and the purlins extend parallel to the sleepers (not shown) of the frame of the roof frame 20. The profiles 202 which extend along the end faces form the crosspieces of said frame frame 20.

Les bac-aciers formant la couverture 21 recouvrent les pannes. Les ondes ou nervures de chaque bac-acier s'étendent orthogonalement aux pannes, c'est-à-dire parallèlement aux long-pans formés par les faces murales 81 latérales.The steel trays forming the cover 21 cover the purlins. The waves or ribs of each steel tank extend orthogonally to the purlins, that is to say parallel to the long sides formed by the side wall faces 81.

Dans l'exemple illustré aux figures, chaque face murale comprend un cadre. Chaque cadre peut recevoir au moins un panneau logé dans ledit cadre. Ledit panneau est de préférence un panneau sandwich. Ledit cadre comprend deux montants tubulaires reliés l'un à l'autre par une traverse ou longeron inférieur(e) et une traverse ou longeron supérieur(e). Le cadre du châssis de toiture peut être formé desdits longerons et traverses supérieurs.In the example illustrated in the figures, each wall face comprises a frame. Each frame can receive at least one panel housed in said frame. Said panel is preferably a sandwich panel. Said frame comprises two tubular uprights connected to each other by a crossbar or lower beam (e) and a crossbar or upper spar (e). The frame of the roof frame may be formed of said longitudinal members and upper sleepers.

La construction comprend un équipement 3 de protection anti-chute couplé à la toiture 2. Ledit équipement 3 est apte à prendre une configuration active selon laquelle il forme un système de barrières anti-chute au niveau de la périphérie de la toiture, et une configuration inactive dans laquelle ledit équipement est rabattu contre la couverture de la toiture. L'équipement 3 de protection anti-chute est couplé à la toiture aussi bien en position active qu'inactive.The construction comprises a fall protection equipment 3 coupled to the roof 2. Said equipment 3 is able to take an active configuration in which it forms a system of anti-fall barriers at the periphery of the roof, and a configuration inactive in which said equipment is folded against the cover of the roof. The fall protection equipment 3 is coupled to the roof both in the active and inactive position.

Dans l'exemple illustré aux figures, en configuration inactive, ledit équipement 3 de protection antichute s'escamote dans le cadre du châssis 20 de toiture 2 (figure 5). Autrement dit, en configuration active, ledit équipement s'étend en saillie de la toiture, tandis qu'en configuration inactive, ledit équipement 3 rentre dans l'encombrement de la toiture. Ainsi, en position inactive ledit équipement 3 d'un premier module ne gêne pas la mise en place d'un deuxième module sur le premier module.In the example illustrated in the figures, in an inactive configuration, said fall protection equipment 3 is retracted in the frame of the roof frame 2 (FIG. figure 5 ). In other words, in active configuration, said equipment extends projecting from the roof, while in the inactive configuration, said equipment 3 enters the overall dimensions of the roof. Thus, in the inactive position said equipment 3 of a first module does not interfere with the introduction of a second module on the first module.

La construction est équipée de moyens de commande pour commander le passage de l'équipement 3 de sa configuration active à sa configuration inactive.The construction is equipped with control means for controlling the passage of the equipment 3 from its active configuration to its inactive configuration.

Lesdits moyens de commande sont agencés de manière à permettre à un opérateur d'actionner lesdits moyens de commande depuis l'extérieur de la construction 1, éventuellement après avoir débloqué lesdits moyens de commande comme détaillé ci-après.Said control means are arranged to allow an operator to operate said control means from outside the construction 1, possibly after unlocking said control means as detailed below.

Chacun des deux garde-corps latéraux 31 comprend deux portions 31A, 31 B disposées sur la toiture 2 au dessus et le long d'une face latérale 81. Chaque garde-corps 32 et chaque portion 31A, 31 B de garde-corps 31 se présente sous la forme d'une barrière présentant des montants et lisses tubulaires.The protective equipment 3 comprises, on the one hand, two end guard rails 32 which extend respectively above and along the end faces 82, and on the other hand, two guardrails 31 lateral which extend above and along the side faces 81. Each of the two side railings 31 comprises two portions 31A, 31B arranged on the roof 2 above and along a lateral face 81. Each railing 32 and each portion 31A, 31B of railing 31 is present in the form of a barrier having uprights and tubular stringers.

Avantageusement, chacune des portions 31A, 31 B de garde-corps latéral 31 est munie d'un élément supplémentaire, appelé portillon, monté mobile, de préférence par coulissement ou par articulation, par rapport à ladite portion 31A, 31 B de garde-corps latéral, entre une position active dans laquelle elle ferme le passage entre les deux portions 31A, 31 B de garde-corps latéral et une position inactive dans laquelle elle libère ledit passage pour permettre à un opérateur de passer d'une toiture d'un module à la toiture d'un autre module juxtaposé. Chaque portillon peut être rappelé en position active de fermeture dudit passage. En particulier, en position inactive et en version coulissante, chaque portillon s'escamote au moins partiellement à l'intérieur des tubes creux qui composent la portion de garde-corps latéral correspondante.Advantageously, each of the portions 31A, 31B of side railing 31 is provided with an additional element, called gate, mounted movably, preferably by sliding or by articulation, with respect to said portion 31A, 31B of guardrails lateral, between an active position in which it closes the passage between the two portions 31A, 31B of side railings and an inactive position in which it frees said passage to allow an operator to pass a roof of a module to the roof of another juxtaposed module. Each gate can be recalled in the active position of closing said passage. In particular, in the inactive position and in the sliding version, each door retracts at least partially inside the hollow tubes that make up the corresponding side railing portion.

Les axes de pivotement des garde-corps 31 latéraux ou portions 31 A, 31 B de garde-corps sont parallèles entre eux et orthogonaux aux axes de pivotement des garde-corps d'extrémité 32. Les axes de pivotement sont situés au niveau des pieds des garde-corps 31, 32. Pour rappel, dans l'exemple illustré aux figures, le cadre 20 du châssis de toiture comprend deux longerons parallèles aux faces latérales et deux traverses parallèles aux faces d'extrémité.The pivoting axes of the side railings 31 or portions 31 A, 31 B of guardrails are parallel to each other and orthogonal to the pivot axes of the end railings 32. The pivot axes are located at the level of the feet railings 31, 32. As a reminder, in the example illustrated in the figures, the frame 20 of the roof frame comprises two longitudinal members parallel to the side faces and two cross members parallel to the end faces.

L'axe de pivotement de chaque garde-corps 31 latéral ou de chaque portion de garde-corps 31 latéral est parallèle aux longerons du cadre de châssis de toiture et l'axe de pivotement de chaque garde-corps 32 d'extrémité est parallèle aux traverses du cadre de châssis de toiture.The pivot axis of each side guard 31 or of each side railing portion 31 is parallel to the side members of the roof frame frame and the pivot axis of each end guard rail 32 is parallel to the cross members of the roof frame frame.

Ledit équipement 3 comprend, pour chaque garde-corps 31, 32, des platines 341, 342 de fixation et des liaisons de pivotement entre les garde-corps 31, 32 et leur platine 341, 342 respective.Said equipment 3 comprises, for each railing 31, 32, mounting plates 341, 342 and pivot links between the guardrails 31, 32 and their plate 341, 342 respectively.

Pour chaque garde-corps latéral 31 ou portion de garde corps 31 latéral, ladite platine 341, appelée platine long-pan, est fixée sur la couverture 21 et de préférence sur le longeron 201 du cadre 20 situé du côté de la face formant long-pan le long de laquelle s'étend ledit garde-corps latéral 31 ou ladite portion de garde corps 31 latéral. En particulier, dans l'exemple illustré aux figures, chaque portion de garde-corps 31 latéral comprend deux pieds chacun couplés à une platine.For each side railing 31 or 31 sideguard portion, said plate 341, called platinum long-pan, is fixed on the cover 21 and preferably on the spar 201 of the frame 20 located on the side of the long-side face. pan along which extends said lateral guard rail 31 or said side guard portion 31. In particular, in the example illustrated in the figures, each portion of guard rail 31 laterally comprises two feet each coupled to a plate.

Pour chaque garde-corps 32 d'extrémité, ladite platine 342, appelée platine pignon, est fixée sur la couverture 21. En particulier, dans l'exemple illustré aux figures, chaque portion de garde-corps 32 d'extrémité comprend deux pieds couplés chacun à une platine.For each end railing 32, said plate 342, called the pinion plate, is fixed on the cover 21. In particular, in the example illustrated in the figures, each end railing portion 32 comprises two coupled feet. each to a platinum.

Chacun des garde-corps 31, 32 ou portion 31 A, 31 B de garde-corps 31 est monté pivotant entre une position active dressée, en formant un angle de l'ordre de 80° avec l'horizontale, et une position inactive rabattue contre la couverture de la toiture.Each of the guardrails 31, 32 or 31A, 31B of railing portion 31 is pivotally mounted between an erected active position, forming an angle of the order of 80 ° with the horizontal, and an inactive position folded against the roof covering.

Lesdits moyens de commande comprennent un système de lien 6 souple qui est lié audit équipement 3 de protection anti-chute. On entend par lien souple un élément longiligne, de type fil, câble ou corde.Said control means comprise a flexible link system 6 which is connected to said fall protection equipment 3. By flexible link is meant an elongated element, wire, cable or rope type.

Ledit système de lien 6 comprend un lien 4 qui présente une partie 40 formant une partie 40 saisissable par un utilisateur extérieur. La partie 40 de saisie s'étend dans le périmètre de la toiture, en particulier en vue de dessus de la construction, c'est-à-dire en projection dans le plan moyen de la toiture, hors du périmètre de la toiture 2 pour pouvoir être saisie par un utilisateur depuis l'extérieur de la construction 1. Cette partie de saisie 40 est prolongée par une partie 41 intérieure qui s'étend à l'intérieur du périmètre de sécurité défini par l'équipement en position active. Cette partie 41 passe au travers d'un élément 8 de renvoi d'angle de type anneau ou poulie, pour être orienté vers un garde-corps d'extrémité 32 et passer au travers d'un anneau 7 situé au niveau d'un garde-corps corps d'extrémité 32 comme détaillé ci-après.Said link system 6 comprises a link 4 which has a part 40 forming a part 40 which can be grasped by an external user. The gripping portion 40 extends in the perimeter of the roof, in particular in top view of the construction, that is to say in projection in the mean plane of the roof, outside the perimeter of the roof 2 for It can be entered by a user from outside the construction 1. This gripping portion 40 is extended by an inner portion 41 which extends within the security perimeter defined by the equipment in the active position. This part 41 passes through a ring or pulley-type angle-of-turn element 8, to be oriented towards an end railing 32 and pass through a ring 7 situated at a level of a guard. body end body 32 as detailed below.

Ladite partie 41 du lien repart vers le garde-corps d'extrémité 32 opposé pour, de manière similaire, passer à travers un autre anneau situé au niveau dudit garde-corps d'extrémité 32 opposé. La partie 41 du lien 4 ressort de l'anneau pour revenir vers l'élément 8 de renvoi d'angle et se prolonge par une partie 40 s'étendant hors de la construction en doublant l'autre partie 40 du lien.Said portion 41 of the link returns to the opposite end rail 32 to similarly pass through another ring located at said opposite end rail 32. The portion 41 of the link 4 leaves the ring to return to the element 8 of the angle of return and is extended by a portion 40 extending out of the construction by doubling the other part 40 of the link.

Ainsi les extrémités libres du lien 4 s'étendent d'un côté de la construction à l'extérieur de la construction. Comme illustré à la figure 9, la ou chaque partie 40 du lien 4 peut s'étendre hors de la construction en sortant au niveau d'un longeron 201 soit en passant à travers le longeron 201 (configuration CF1) par un orifice ménagé dans le longeron 201, soit en passant au dessus dudit longeron (configuration CF2). En variante, comme illustré à la figure 8, la ou chaque partie 40 du lien 4 peut s'étendre hors de la construction en sortant au niveau d'une traverse 202 du cadre du châssis de la toiture.Thus the free ends of the link 4 extend from one side of the building to the outside of the building. As illustrated in figure 9 , the or each portion 40 of the link 4 may extend out of the construction leaving at a spar 201 or passing through the spar 201 (CF1 configuration) by a hole in the spar 201, or passing above said spar (configuration CF2). Alternatively, as illustrated in figure 8 , the or each portion 40 of the link 4 may extend out of the construction exiting at a cross 202 of the frame of the frame of the roof.

Dans l'exemple illustré aux figures, les parties de saisie 40, en particulier les extrémités libres dudit lien 4, s'étendent d'un même côté de la construction, hors de la construction, pour pouvoir être saisies depuis l'extérieur.In the example illustrated in the figures, the gripping portions 40, in particular the free ends of said link 4, extend on the same side of the construction, out of the construction, to be seized from the outside.

Pour chaque garde-corps 32 d'extrémité, le système de lien comprend aussi un lien 42 dit extérieur qui s'étend du côté extérieur d'un garde-corps d'extrémité 32 tout en étant fixée aux garde-corps latéraux 31. Le côté extérieur d'un garde-corps correspondant au côté orienté vers l'extérieur du périmètre de sécurité défini par l'équipement 3.For each end guard 32, the link system also includes an outer link 42 extending from the outer side of an end guard 32 while attached to the side railings 31. The outer side of a railing corresponding to the outward-facing side of the safety perimeter defined by the equipment 3.

Ainsi dans l'exemple illustré aux figures, le système de lien comprend un lien 4 présentant une partie 40 et une partie 41, un lien 42 distinct du lien mais relié à la partie 41 du lien 4 du côté d'un garde-corps d'extrémité 32 par un anneau 7 et un autre lien 42 relié à la partie 41 du lien 4 du côté de l'autre garde-corps d'extrémité 32 par un autre anneau.Thus, in the example illustrated in the figures, the link system comprises a link 4 having a portion 40 and a portion 41, a link 42 distinct from the link but connected to the portion 41 of the link 4 on the side of a railing. end 32 by a ring 7 and another link 42 connected to the portion 41 of the link 4 on the side of the other end guard rail 32 by another ring.

En particulier, dans l'exemple illustré aux figures, chaque anneau 7 est agencé de sorte que les parties 41, 42 qu'il lie passent au dessus du garde-corps d'extrémité 32 correspondant.In particular, in the example illustrated in the figures, each ring 7 is arranged so that the parts 41, 42 that binds pass over the end guard 32 corresponding.

Chaque garde-corps d'extrémité 32 est avantageusement muni de moyens de guidage 34 de la partie 41 et de la partie 42 du système de lien correspondant. Ces moyens de guidage 34 sont situés en partie supérieure et au milieu de la longueur pour limiter le risque que les parties 41,42 du système de lien correspondant ne dévient un côté ou de l'autre le long du garde-corps d'extrémité 32. Ces moyens de guidage 34 peuvent être formés, soit d'un anneau de guidage commun aux portions du lien 42 qui s'étendent l'une vers l'un des garde-corps latéraux, l'autre vers le garde-corps opposé, soit de deux anneaux de guidage, l'un étant traversé par l'une des portions du lien 42, l'autre anneau de guidage étant traversé par l'autre portion dudit lien 42.Each end railing 32 is advantageously provided with guide means 34 of the portion 41 and the portion 42 of the corresponding link system. These guide means 34 are located in the upper part and in the middle of the length to limit the risk that the parts 41,42 of the corresponding link system deviate one side or the other along the end railing 32 These guide means 34 can be formed either of a common guide ring to the portions of the link 42 which extend one towards one of the side railings, the other towards the opposite railing, either of two guide rings, one being traversed by one of the portions of the link 42, the other guide ring being traversed by the other portion of said link 42.

Le lien qui forme la partie 41 traverse chaque anneau 7 et, comme le montre les figures, est ramené sur lui-même pour obtenir une partie 40 doublée dont les extrémités libres s'étendent en dehors de la construction.The link forming the portion 41 passes through each ring 7 and, as shown in the figures, is brought back on itself to obtain a doubled portion 40 whose free ends extend outside the construction.

Ainsi une fois que l'opérateur n'a plus l'utilité du lien 4 il peut lâcher l'une des extrémités et tirer sur l'autre pour, depuis l'extérieur de la construction, ressortir la partie 41 de l'anneau correspondant et retirer ainsi le lien 4 pour qu'il ne pende pas.Thus, once the operator no longer has the utility of the link 4, he can let go of one of the ends and pull on the other to, from the outside of the construction, leave the part 41 of the corresponding ring. and remove the link 4 so that it does not hang.

Pour chaque garde-corps d'extrémité 32, chaque portion du lien formant la partie extérieure 42 qui s'étend depuis l'anneau 7 situé au niveau de la zone supérieure du garde-corps d'extrémité, vers un garde-corps latéral, descend en passant à travers un anneau 22, appelé anneau de renvoi, solidaire de la toiture, en particulier de la couverture, pour remonter jusqu'à une zone supérieure du garde-corps latéral correspondant auquel il est fixé. Pour chaque garde-corps corps d'extrémité, on peut prévoir que les deux portions du lien 42 passent par un même anneau de renvoi22 ou chacun par un anneau de renvoi distinct de l'autre anneau de renvoi.For each end railing 32, each portion of the link forming the outer portion 42 which extends from the ring 7 located at the upper zone of the end railing, towards a side railing, descends through a ring 22, called return ring, secured to the roof, in particular the cover, to go up to an upper area of the corresponding side rail to which it is attached. For each guard body end body, it can be provided that the two portions of the link 42 pass through the same return ring22 or each by a return ring separate from the other ring return.

Le lien 4 formant les parties 40, 41 peut être retiré tandis que le lien formant la partie 42 est destiné à rester fixé auxdits garde-corps latéraux.The link 4 forming the parts 40, 41 can be removed while the link forming the portion 42 is intended to remain attached to said side railings.

Chaque partie extérieure 42 est agencée de manière à venir en appui contre plusieurs zones du garde-corps d'extrémité 32 associé lorsque le lien est soumis à un effort de traction.Each outer portion 42 is arranged to abut against several areas of the associated end rail 32 when the link is subjected to a tensile force.

Un tel agencement des liens avec des anneaux ou poulies formant des élément de passage ou de renvoi de lien, avec en particulier un anneau ou poulie de renvoi central 8, et un anneau 7 de liaison supérieur par garde-corps d'extrémité, permettent de faire sortir le ou chaque lien d'un seul côté de la construction et ainsi de permettre de commander le passage en position active de chaque garde-corps qui s'étend le long d'un côté de la construction, d'un seul côté sans que l'opérateur ait à relever un à un chaque garde-corps en tournant autour de la construction.Such an arrangement of links with rings or pulleys forming passage elements or link return, with in particular a central ring or return pulley 8, and an upper linkage ring 7 by end railing, allow to pull out the or each link on one side of the construction and thus allow to control the passage in the active position of each railing that extends along one side of the construction, a only side without the operator having to raise one by one each railing while turning around the construction.

Bien entendu, d'autres configurations du système de lien sont envisageables.Of course, other configurations of the link system are conceivable.

Préférentiellement, la construction est équipée de moyens de blocage par exemple formés d'un ou de plusieurs crochets, permettant d'accrocher le ou les liens, et ainsi de maintenir l'équipement de protection en position inactive.Preferably, the construction is equipped with locking means, for example formed of one or more hooks, for hanging the link or links, and thus to keep the protective equipment in the inactive position.

Lorsque l'opérateur souhaite commander le passage en position active dudit équipement, l'opérateur défait alors le ou les liens par rapport aux moyens de blocage correspondant, ce qui libère le ou les liens de sorte que l'équipement de protection repasse automatiquement en position active à l'aide des moyens de rappels.When the operator wishes to control the passage to the active position of said equipment, the operator then defeats the link or links relative to the corresponding blocking means, which releases the link or links so that the protective equipment automatically returns to position active by means of reminders.

Lesdits garde-corps latéraux 31 sont agencés pour venir partiellement au dessus des garde-corps 32 d'extrémité, de sorte que le passage en position rabattue, des garde-corps latéraux 31, entraine le rabat des garde-corps d'extrémité 32. En variante, on pourrait prévoir que ce soient les garde-corps 32 d'extrémité qui soient positionnés partiellement au dessus des garde-corps 31 latéraux.Said side rails 31 are arranged to come partially above the end railings 32, so that the passage in the folded position, side railings 31, causes the flap of the end railings 32. Alternatively, it could be provided that it is the end railings 32 are positioned partially above the railings 31 side.

Les garde-corps se chevauchent au niveau de leurs angles supérieurs non seulement pour permettre en rabattant certains garde-corps d'entrainer le rabat d'autres garde-corps mais aussi pour, en position active, fermer l'équipement 3 au niveau des coins définis entre lesdits garde-corps.The railings overlap at their upper angles not only to allow folding some railings to cause the flap of other railings but also to, in the active position, close the equipment 3 at the corners defined between said guardrails.

Les garde-corps 32 d'extrémité qui sont agencés pour, en position inactive, se retrouver sous les garde-corps latéraux 31, présentent des parties déformées ou cintrées vers la couverture 21 pour recevoir les garde-corps 31 latéraux au niveau de leur zone de contact afin de réduire l'encombrement de l'équipement 3 en position inactive. Les parties déformées ou cintrée s'étendent en position inactive des garde-corps entre deux ondes ou nervures de bac-acier. Ainsi, en configuration inactive de l'équipement, lesdits garde-corps sont contenus dans l'encombrement de la toiture.The end railings 32 which are arranged to, in the inactive position, be found under the side railings 31, have parts deformed or bent towards the cover 21 to receive the side railings 31 at their zone. contact to reduce the size of the equipment 3 in the inactive position. Deformed or arched parts extend into position Inactive railings between two waves or ribs of steel tank. Thus, in the inactive configuration of the equipment, said guardrails are contained in the overall dimensions of the roof.

Chaque garde-corps 31, 32 ou portion de garde-corps comprend des moyens de rappel (non représentés), tels qu'un ressort de torsion, agencés pour rappeler en configuration active le garde-corps ou portion de garde-corps correspondant.Each railing 31, 32 or guardrail portion comprises return means (not shown), such as a torsion spring, arranged to recall in active configuration the railing or portion of railing corresponding.

Chaque garde-corps 31, 32 ou portion de garde-corps comprend aussi une butée de limitation du déplacement du garde-corps lors de son passage de sa configuration inactive à sa configuration active.Each railing 31, 32 or guardrail portion also comprises a stop for limiting the movement of the guardrail during its transition from its inactive configuration to its active configuration.

Lesdits moyens de rappel présentent une force de rappel adaptée à maintenir les garde-corps 31, 32 en position active. En particulier, les moyens de rappel comprennent des ressorts couplés aux garde-corps 31 et des ressorts couplés aux garde-corps 32 de forces de rappel différentes.Said return means have a return force adapted to maintain the guardrails 31, 32 in the active position. In particular, the return means comprise springs coupled to the guardrails 31 and springs coupled to the guardrails 32 of different return forces.

Plus précisément les ressorts de chaque garde-corps d'extrémité 32 sont dimensionnés de manière à pouvoir rappeler le garde-corps 32 en position active, en l'absence de blocage ou verrouillage du garde-corps, quelle que soit sa position.More precisely the springs of each end railing 32 are sized so as to be able to return the railing 32 in the active position, in the absence of locking or locking the railing, regardless of its position.

Les ressorts de chaque garde-corps latéral 31 sont dimensionnés de manière à rappeler le garde-corps 31 en position active à partir du moment où celui-ci forme un angle donné avec le plan moyen de la toiture.The springs of each side railing 31 are sized to return the railing 31 in the active position from the moment when it forms a given angle with the average plane of the roof.

Ainsi les moyens de rappel sont configurés de sorte que, lorsque chaque garde-corps d'extrémité 32 se relève, le garde-corps 32 d'extrémité pousse chaque garde-corps latéral 31, ce qui relève ledit garde-corps latéral 31 d'un angle donné correspondant à un angle pour lequel les moyens de rappel dudit garde-corps latéral sont aptes à poursuivre son redressement en position active.Thus the return means are configured so that, when each end rail 32 is raised, the end rail 32 pushes each side rail 31, which raises said side rail 31 of a given angle corresponding to an angle for which the return means of said side railing are able to continue its recovery in position active.

Au cours de la traction sur les liens du système de lien 6, le garde-corps latéral 31 est ainsi rabattu à l'encontre de ses moyens de rappel jusqu'à un certain angle avec la verticale, angle au-delà duquel lesdits moyens de rappel associés au garde-corps 31 ne sont plus suffisants pour le rappeler, de sorte que le garde-corps latéral 31 s'affaisse par son propre poids contre le garde-corps d'extrémité 32.During traction on the links of the link system 6, the side railing 31 is thus folded against its return means to a certain angle with the vertical angle beyond which said means of recall associated with the guardrail 31 are no longer sufficient to recall it, so that the side railing 31 collapses by its own weight against the end railing 32.

En outre, la partie 42 passant derrière le garde-corps d'extrémité 32, la traction exercée sur le système de lien entraine un appui de la partie 42 du système de lien sur le garde-corps d'extrémité 32, ce qui peut faciliter le déplacement du garde-corps d'extrémité 32 en position inactive contre la couverture malgré l'effort de rappel exercé par ses moyens de rappel. Ainsi, si un lien du système de lien se rompt, les garde-corps 31, 32 sont automatiquement redressés par leurs moyens de rappel.In addition, the portion 42 passing behind the end railing 32, the traction exerted on the linkage system causes a support of the portion 42 of the linkage system on the end railing 32, which can facilitate the movement of the end guard 32 in the inactive position against the cover despite the return force exerted by its return means. Thus, if a link of the link system breaks, the guardrails 31, 32 are automatically adjusted by their return means.

Dans l'exemple illustré aux figures, le système de lien s'étend au dessus de la couverture. En variante, on peut prévoir que le système de lien s'étende au moins en partie sous la couverture. La partie du système de lien qui s'étend dans le périmètre de la toiture peut passer le long (sous ou dessus) d'une onde ou nervure de bac-acier pour favoriser le guidage du système de lien.In the example shown in the figures, the link system extends above the cover. Alternatively, it can be expected that the link system extends at least partially under the cover. The part of the link system that extends into the perimeter of the roof can pass along (under or over) a tubular steel wave or rib to promote guidance of the link system.

Le système de lien est ainsi couplé aux garde-corps 31, 32 et présente au moins une extrémité libre s'étendant hors de la construction pour permettre à un utilisateur extérieur de tirer dessus et ainsi de rabattre les garde-corps ou à l'inverse permettre de libérer le système de lien pour laisser les moyens de rappels redresser les garde-corps.The linkage system is thus coupled to the guardrails 31, 32 and has at least one free end extending out of the construction to allow an outside user to pull on and thus fold down the guardrails or vice versa to free the link system to allow the means of reminders to straighten the railings.
