  • the container is set up on the platform, which rests at the bottom. During the removal of the container, the platform rises, under the effect of the counterweight that goes down. The platform stabilizes on the surface and closes the pit.

Description

CONTEXTE ET ARRIERE-PLAN TECHNOLOGIQUEBACKGROUND AND TECHNOLOGICAL BACKGROUND

La présente invention se rapporte au domaine des conteneurs enterrés dans une fosse. Plus précisément, l'invention concerne un système d'accueil d'un conteneur enterré comprenant une fosse comprenant un fond et des parois latérales délimitant à l'intérieur un espace de réception pour un conteneur, ladite fosse étant ouverte sur sa partie supérieure.The present invention relates to the field of containers buried in a pit. More specifically, the invention relates to a system for receiving a buried container comprising a pit comprising a bottom and side walls delimiting inside a receiving space for a container, said pit being open on its upper part.

Le développement de la récupération des déchets afin de les recycler a entrainé la mise en place dans des espaces publiques de conteneurs à déchets collectifs, généralement affectés à un type particulier de déchets (plastiques, verres, cartons ...). Afin de minimiser l'encombrement de ces conteneurs, notamment en milieu urbain, ainsi que pour des raisons esthétiques, certains de ces conteneurs sont enterrés, c'est-à-dire qu'ils sont disposés sous le niveau du sol, en ne laissant dépasser qu'un collecteur par lequel les utilisateurs peuvent y introduire leurs déchets.The development of waste recovery for recycling has led to the establishment of public waste containers in public areas, generally assigned to a particular type of waste (plastics, glasses, cardboard ...). In order to minimize the bulk of these containers, particularly in urban areas, as well as for aesthetic reasons, some of these containers are buried, that is to say they are located below the ground level, leaving no exceed a collector by which users can introduce their waste.

Un conteneur enterré nécessite donc la mise en place dans le sol d'une fosse comprenant un fond et des parois latérales délimitant à l'intérieur un espace de réception pour ledit conteneur, et dont la partie supérieure est ouverte afin de permettre la mise en place et l'enlèvement dudit conteneur, et de permettre au collecteur de dépasser du sol. La fosse est donc située dans le sol, la partie supérieure de celle-ci affleurant au niveau du sol.A buried container therefore requires the establishment in the ground of a pit comprising a bottom and side walls delimiting inside a receiving space for said container, and whose upper part is open to allow the establishment and removing said container, and allowing the collector to protrude from the ground. The pit is located in the ground, the upper part of it flush with the ground.

Cette configuration, si elle permet de répondre aux contraintes de réduction de l'encombrement et de dissimulation des conteneurs, présente une contrainte supplémentaire. La partie supérieure de la fosse étant ouverte, en l'absence de conteneur à l'intérieur de celle-ci, il existe un danger de chute non négligeable dans l'espace de réception du conteneur, en particulier pour les enfants.This configuration, if it makes it possible to meet the constraints of reducing the size and concealment of the containers, presents an additional constraint. The upper part of the pit being open, in the absence of a container inside thereof, there is a significant danger of falling in the receiving space of the container, especially for children.

Il est nécessaire de prévoir des dispositifs de sécurité pour prévenir toute chute. Il a été proposé d'entourer l'emplacement de la fosse par des barrières afin d'en interdire l'accès. Cependant, la sécurisation est alors imparfaite puisque de telles barrières peuvent être franchies. En outre, lors de l'enlèvement et de la mise en place du conteneur, celui-ci doit être hissé et déplacé au-dessus de ces barrières. Il arrive fréquemment que le conteneur entre en collision avec les barrières, fragilisant celle-ci et compromettant la sécurisation du site.It is necessary to provide safety devices to prevent any fall. It was proposed to surround the pit location with gates to prevent access. However, security is imperfect since such barriers can be crossed. In addition, when removing and placing the container, it must be hoisted and moved over these barriers. It often happens that the container collides with the barriers, weakening it and compromising the security of the site.

Il a donc été proposé de munir la fosse d'un mécanisme d'obturation de sa partie ouverte. Un tel mécanisme comprend généralement une plate-forme ou un volet venant fermer la partie ouverte en l'absence de conteneur.It has therefore been proposed to provide the pit with a closure mechanism of its open part. Such a mechanism generally comprises a platform or a shutter that closes the open part in the absence of a container.

La plate-forme se déplace verticalement dans la fosse depuis le fond de celle-ci jusqu'à la surface ouverte qu'elle vient fermer. Un contrepoids est relié à la plate-forme par un câble et une poulie, la masse de ce contrepoids étant supérieure à la masse d'un adulte, et inférieure à la masse d'un conteneur vide.The platform moves vertically in the pit from the bottom of the latter to the open surface it comes close. A counterweight is connected to the platform by a cable and a pulley, the mass of this counterweight being greater than the mass of an adult, and less than the mass of an empty container.

Le conteneur est mis en place sur la plate-forme, qui repose au fond. Lors de l'enlèvement du conteneur, la plate-forme remonte, sous l'effet du contrepoids qui descend. La plate-forme se stabilise à la surface et ferme la fosse. Lors de la remise en place du conteneur, le poids de celui-ci fait redescendre la plate-forme au fond et remonter le contrepoids.The container is set up on the platform, which rests at the bottom. During the removal of the container, the platform rises, under the effect of the counterweight that goes down. The platform stabilizes on the surface and closes the pit. When the container is put back in place, the weight of the container causes the platform to descend to the bottom and raise the counterweight.

Cette configuration a cependant des inconvénients. Le contrepoids est toujours suspendu par le câble le reliant à la plate-forme. Le câble est donc en permanence sollicité en tension. Il en résulte un vieillissement accéléré du câble, et donc des risques de rupture de celui-ci. Un autre inconvénient tient au fait que l'obturation n'est obtenue qu'en l'absence de masse importante sur la plate-forme, inférieure à la masse du contrepoids. Or, plusieurs enfants se trouvant ensemble sur la plate-forme ou un véhicule automobile peuvent dépasser la masse du contrepoids. La plate-forme redescend alors, n'obturant plus la fosse.This configuration, however, has disadvantages. The counterweight is always suspended by the cable connecting it to the platform. The cable is therefore permanently stressed in tension. This results in accelerated aging of the cable, and therefore the risk of rupture thereof. Another disadvantage is that the shutter is obtained in the absence of significant mass on the platform, less than the mass of the counterweight. However, many children who are together on the platform or a motor vehicle may exceed the mass of the counterweight. The platform then descends, no longer closing the pit.

Des systèmes de verrouillage manuel de la plate-forme en position haute ont été proposés. Cependant, ceux-ci peuvent être endommagés ou intentionnellement déverrouillés, ce qui limite leur intérêt.Manual locking systems of the platform in the high position have been proposed. However, they can be damaged or intentionally unlocked, which limits their interest.

Dans une autre configuration, des volets articulés par des charnières en partie haute des parois latérales de la fosse sont sollicités par des ressorts pour venir obturer la partie ouverte de la fosse. La raideur des ressorts est déterminée pour être inférieure à la pression exercée par le poids d'un conteneur vide, de sorte que lors de la mise en place du conteneur, les volets reprennent une position repliée laissant ouverte la fosse. Un mécanisme verrouille les volets en position haute. Ce mécanisme est pourvu de pédales faisant saillie au-dessus des volets pour commander le déverrouillage. L'actionnement accidentel ou intentionnel de ces pédales de déverrouillage peut entraîner l'ouverture des volets, la fosse se retrouvant alors ouverte, annulant la sécurisation attendue. Par ailleurs, lorsque le conteneur est en place, les volets sont rétractés, et les ressorts sont alors déformés en compression. Comme le conteneur est en place dans la fosse la quasi-totalité du temps, les ressorts sont compressés pratiquement en permanence. Il en résulte une usure rapide de ceux-ci et une altération de leurs qualités mécaniques qui peut compromettre la fermeture des volets permettant leur verrouillage.In another configuration, flaps articulated by hinges at the upper part of the side walls of the pit are biased by springs to close off the open part of the pit. The stiffness of the springs is determined to be less than the pressure exerted by the weight of an empty container, so that when placing the container, the flaps take up a folded position leaving the pit open. A mechanism locks the shutters in the up position. This mechanism is provided with pedals projecting above the flaps to control the unlocking. Accidental or intentional actuation of these unlocking pedals may cause the flaps to open, leaving the pit open, canceling the expected securing. Moreover, when the container is in place, the flaps are retracted, and the springs are then deformed in compression. As the container is in place in the pit almost all of the time, the springs are compressed almost continuously. This results in a rapid wear thereof and an alteration of their mechanical properties that can compromise the closure of the shutters for locking.

PRESENTATION DE L'INVENTIONPRESENTATION OF THE INVENTION

L'invention a pour but de résoudre au moins certains des inconvénients précités, en proposant un ensemble assurant la sécurisation de la fosse par une fermeture automatique de sa partie ouverte lors de l'enlèvement d'un conteneur et la réouverture automatique de celle-ci lors de la remise en place du conteneur, sans risque d'ouverture accidentelle et sans sollicitation mécanique de l'ensemble lorsque le conteneur est en place.The invention aims to solve at least some of the aforementioned drawbacks, by proposing an assembly ensuring the securing of the pit by an automatic closing of its open part during the removal of a container and the automatic reopening thereof when replacing the container, without risk of accidental opening and without mechanical stress of the assembly when the container is in place.

  • the platform hangs at the top of the pit while the removal of the container continues,
  • the withdrawal force exerted by the container uncouples the coupling members.

De préférence, l'ensemble comprend un cadre coiffant la périphérie de la fosse et un mécanisme de verrouillage adapté pour verrouiller audit cadre la plate-forme dans sa position haute, et :

  • la mise en place du conteneur sur la plate-forme entraîne le déverrouillage de la plate-forme sur le cadre lors de la mise en place du conteneur dans la fosse, et

Preferably, the assembly comprises a frame capping the periphery of the pit and a locking mechanism adapted to lock said frame to the platform in its upper position, and:
  • placing the container on the platform causes the platform to be unlocked on the frame when the container is placed in the pit, and
  • removal of the container when the platform has reached the high position causes locking of the platform on the frame.

DESCRIPTION DETAILLEEDETAILED DESCRIPTION

En référence aux figures annexées, qui illustrent un mode de réalisation possible à titre non limitatif, l'ensemble d'accueil comprend un conteneur 1, généralement destiné à recevoir des déchets, également appelé cuve. En général le conteneur 1 est en métal, et présente une forme cylindrique ou parallélépipédique, mais d'autres formes et matières peuvent être employées. Couramment, et comme illustré sur les figures, le fond du conteneur 1 est constitué de portes 2 par lesquelles le conteneur 1 peut être vidé des objets qui y ont été introduits par le biais d'un avaloir (non représenté) émergeant de la surface du sol lorsque le conteneur 1 est disposé dans la fosse 3.With reference to the appended figures, which illustrate an embodiment possible in a non-limiting manner, the reception unit comprises a container 1, generally intended to receive waste, also called tank. In general, the container 1 is made of metal, and has a cylindrical or parallelepipedal shape, but other shapes and materials can be used. Commonly, and as illustrated in the figures, the bottom of the container 1 consists of doors 2 through which the container 1 can be emptied of the objects which have been introduced through a drain (not shown) emerging from the surface of the container. soil when the container 1 is disposed in the pit 3.

La fosse 3 un espace de réception pour le conteneur 1 et présente une partie ouverte 4 en haut 5 de la fosse. Le conteneur 1 est mis en place dans la fosse 3 et retiré de celle-ci via cette partie ouverte 5. La fosse 3 est ménagée dans le sol, le haut 5 de la fosse 3 affleurant généralement la surface du sol. La fosse comprend un fond 6 fermant celle-ci en bas. La fosse 3 est typiquement constituée de béton, mais tout autre matériau adapté peut être utilisé, comme par exemple du métal tel que l'acier. La fosse 3 peut présenter toute forme adaptée pour permettre la mise en place et le retrait du conteneur 1.The pit 3 a receiving space for the container 1 and has an open portion 4 at the top 5 of the pit. The container 1 is placed in the pit 3 and removed from it via this open part 5. The pit 3 is formed in the ground, the top 5 of the pit 3 is generally flush with the ground surface. The pit comprises a bottom 6 closing it down. The pit 3 is typically made of concrete, but any other suitable material can be used, such as metal such as steel. The pit 3 may have any suitable shape to allow the introduction and removal of the container 1.

L'ensemble comprend également une plate-forme 7 déplaçable entre une position au fond 6 de la fosse 3 et une position en haut 5 de la fosse 3 dans laquelle l'ouverture de la fosse 3 est obturée par la plate-forme 7. Sur la figure 1, la plate-forme 7 est montrée dans sa position en haut 5 de la fosse 3. Sur la figure 5, la plate-forme 7 est montrée dans sa position au fond 6 de la fosse 3.The assembly also comprises a platform 7 movable between a position at the bottom 6 of the pit 3 and a position at the top 5 of the pit 3 in which the opening of the pit 3 is closed by the platform 7. the figure 1 , the platform 7 is shown in its position at the top 5 of the pit 3. On the figure 5 , the platform 7 is shown in its position at the bottom 6 of the pit 3.

La plate-forme 7 est métallique, et de préférence en acier. C'est la plate-forme 7 qui, par l'obturation de la partie ouverte 4 de la fosse 3, permet de sécuriser celle-ci en empêchant toute chute accidentelle dans la fosse 3.The platform 7 is metallic, and preferably made of steel. It is the platform 7 which, by closing the open part 4 of the pit 3, makes it possible to secure the latter by preventing any accidental fall into the pit 3.

Le conteneur 1 et la plate-forme 7 présentent chacune un organe d'accouplement 8, 9 complémentaire de l'autre, lesdits organes d'accouplement 8,9 étant adaptés pour s'accoupler lors de la mise en place du conteneur 1 et pour se désaccoupler lors du retrait du conteneur 1 en dehors de la fosse 3.The container 1 and the platform 7 each have a coupling member 8, 9 complementary to the other, said coupling members 8, 9 being adapted to mate during the introduction of the container 1 and for to uncouple when removing the container 1 outside the pit 3.

Plus précisément, un organe d'accouplement est un organe mâle 8 et l'autre organe d'accouplement est un organe femelle 9 comprenant un espace d'accouplement 10 pour l'insertion de l'organe mâle 8. Dans l'exemple illustré, c'est l'organe d'accouplement du conteneur 1 qui est l'organe mâle 8 et c'est l'organe d'accouplement de la plate-forme 7 qui est l'organe femelle 9. L'inverse serait également possible.More specifically, a coupling member is a male member 8 and the other coupling member is a female member 9 comprising a coupling space 10 for the insertion of the male member 8. In the illustrated example, it is the coupling member of the container 1 which is the male member 8 and it is the coupling member of the platform 7 which is the female member 9. The opposite would also be possible.

Ainsi que visible sur les figures 2 et 3, l'organe femelle 9 comprend au moins une mâchoire 11 déplaçable entre une position fermée dans laquelle ladite mâchoire 11 obture au moins partiellement l'espace d'accouplement 10 et une position ouverte dans laquelle l'obturation de l'espace d'accouplement 10 est moins importante que dans la position fermée. Ainsi, dans sa position fermée et lorsque l'organe mâle 8 est inséré dans l'espace d'accouplement 10, la mâchoire maintient l'organe mâle 8 dans l'espace d'accouplement 10, comme dans la figure 2, tandis que la position ouverte de la mâchoire 11 permet l'insertion et le retrait de l'organe mâle 8 dans l'espace d'accouplement 10.As visible on the figures 2 and 3 , the female member 9 comprises at least one jaw 11 movable between a closed position in which said jaw 11 at least partially closes the coupling space 10 and an open position in which the closing of the coupling space 10 is less important than in the closed position. Thus, in its closed position and when the male member 8 is inserted into the coupling space 10, the jaw keeps the male member 8 in the coupling space 10, as in the figure 2 , while the open position of the jaw 11 allows insertion and removal of the male member 8 in the coupling space 10.

L'organe mâle 8 fait saillie vers le bas du conteneur 1 et comprend ici une tige 12 s'étendant verticalement terminée par une tête 13 de section plus large que la tige 12. Les surfaces respectives de l'organe mâle 8 et de la mâchoire 11 lorsque l'organe mâle 8 est dans l'espace d'accouplement 10 de l'organe femelle 9 et que la mâchoire 11 est en position fermée présentent des formes adaptées pour éviter le blocage de l'organe mâle 8 par la mâchoire 11. La tête 13 présente ainsi des surfaces convexes, au moins dans la direction verticale, c'est-à-dire dans le sens du déplacement du conteneur 1 lors de son retrait et de sa mise en place. De même, la mâchoire 11 présente une forme convexe dans l'espace d'accouplement 10.The male member 8 projects downwards from the container 1 and here comprises a vertically extending rod 12 terminated by a head 13 of wider section than the rod 12. The respective surfaces of the male member 8 and the jaw 11 when the male member 8 is in the coupling space 10 of the female member 9 and the jaw 11 is in the closed position have forms adapted to prevent the locking of the male member 8 by the jaw 11. The head 13 thus has convex surfaces, at least in the vertical direction, that is to say in the direction of movement of the container 1 during its removal and its introduction. Similarly, the jaw 11 has a convex shape in the coupling space 10.

La mâchoire 11 est sollicitée vers sa position fermée par au moins un ressort de rappel 14 exerçant une force de rappel sur ladite mâchoire 11. Le ressort est disposé de sorte à repousser la mâchoire 11 dans l'espace d'accouplement 10. Ainsi, en l'absence de l'organe mâle 8 dans l'espace d'accouplement 10, comme sur la figure 3, la mâchoire 11 est en position fermée. La mâchoire 11 est montée sur un pivot 15 excentré par rapport à direction de sollicitation du ressort de rappel 13. Ainsi, la mâchoire 11 pivote lorsqu'une force exercée sur elle dépasse la force exercée sur le ressort de rappel 13.The jaw 11 is urged towards its closed position by at least one return spring 14 exerting a restoring force on said jaw 11. The spring is arranged so as to push the jaw 11 into the coupling space 10. Thus, in the absence of the male member 8 in the coupling space 10, as on the figure 3 the jaw 11 is in the closed position. The jaw 11 is mounted on a pivot 15 eccentric with respect to the biasing direction of the return spring 13. Thus, the jaw 11 pivots when a force exerted on it exceeds the force exerted on the return spring 13.

En position fermée, la mâchoire 11 est saillante dans l'espace d'accouplement 10 et forme ainsi dans ledit espace d'accouplement 10 un goulot de section inférieure à celle de la tête 13 de l'organe mâle 8. En position ouverte, la mâchoire 11 libère dans l'espace d'accouplement 10 une section suffisante au passage de la tête 13 de l'organe mâle 8.In the closed position, the jaw 11 protrudes into the coupling space 10 and thus forms in said coupling space 10 a lower section of the neck than the head 13 of the male member 8. In the open position, the jaw 11 releases into the mating space 10 a sufficient section to pass the head 13 of the male member 8.

L'espace d'accouplement 10 présente une extension suffisante dans la direction verticale pour permettre, en position fermée de la mâchoire 11, une course libre des organes d'accouplement : l'organe mâle 8 peut ainsi se déplacer au moins verticalement dans l'espace d'accouplement 10, sans désaccouplement. Cette course libre est d'au moins 15 mm, de préférence d'au moins 30 mm.The coupling space 10 has a sufficient extension in the vertical direction to allow, in the closed position of the jaw 11, a free travel of coupling members: the male member 8 can thus move at least vertically in the coupling space 10, without uncoupling. This free stroke is at least 15 mm, preferably at least 30 mm.

L'ensemble comprend également un cadre 16 coiffant la périphérie de la fosse 3 et un mécanisme de verrouillage 17 adapté pour verrouiller la plate-forme 7 dans sa position haute audit cadre 16. Le cadre 16 est par exemple vissé à la fosse 3.The assembly also comprises a frame 16 covering the periphery of the pit 3 and a locking mechanism 17 adapted to lock the platform 7 in its upper position to said frame 16. The frame 16 is for example screwed to the pit 3.

En référence à la figure 4 qui montre plus en détail un mécanisme de verrouillage 17, la plate-forme 7 comprend des pênes 18 déplaçables entre une position de verrouillage et une position de déverrouillage. En position de verrouillage, les pênes 18 font saillie en dehors de la plate-forme 7 tandis que les pênes 18 sont rétractés en position de déverrouillage. Des ressorts de pêne 19 sollicitent les pênes 18 vers leurs positions de verrouillage.With reference to the figure 4 which shows in more detail a locking mechanism 17, the platform 7 comprises bolts 18 movable between a locking position and an unlocking position. In the locking position, the bolts 18 protrude outside the platform 7 while the bolts 18 are retracted in the unlocked position. Bolt springs 19 bias the bolts 18 toward their locking positions.

Le cadre 16 comprend des gâches 20 configurées pour accueillir les pênes 18 en position de verrouillage lorsque la plate-forme 7 est dans sa position haute. De préférence, les extrémités des pênes 18 destinées à s'engager dans les gâches 20 présentent des chanfreins orientés vers le haut, et des surfaces planes orientées vers le bas. Chaque ressort de pêne 19 est dimensionné pour exercer sur les pênes 18 une force supérieure à 100 N, de préférence dans une direction essentiellement perpendiculaire à la verticale. La course des pênes 18 entre leur position de verrouillage et leur position de déverrouillage est par exemple de 17 mm.The frame 16 includes strikes 20 configured to receive the bolts 18 in the locking position when the platform 7 is in its high position. Preferably, the ends of the bolts 18 intended to engage the latches 20 have upwardly facing chamfers, and downwardly facing planar surfaces. Each bolt spring 19 is sized to exert on the bolts 18 a force greater than 100 N, preferably in a direction substantially perpendicular to the vertical. The stroke of the bolts 18 between their locking position and their unlocking position is for example 17 mm.

La plate-forme 7 comprend des ouvertures 21 en face desquelles s'étendent partiellement les pênes 18 en position de verrouillage. En position de déverrouillage, les pênes 18 libèrent ces ouvertures 21. Plus précisément, les pênes 18 comportent des trous 22, qui en position de verrouillage, sont partiellement excentrés par rapport aux ouvertures 21 de la plate-forme 7, et sont centrés par rapport auxdites ouvertures 21 en position de déverrouillage.The platform 7 comprises openings 21 in front of which partially extend the bolts 18 in the locking position. In the unlocked position, the bolts 18 release these openings 21. Specifically, the bolts 18 comprise holes 22, which in the locking position, are partially eccentric with respect to the openings 21 of the platform 7, and are centered relative at said openings 21 in the unlocked position.

Le conteneur 1 comprend des pieds 23, et les ouvertures 21 de la plate-forme 7 sont adaptées pour recevoir lesdits pieds 23. De préférence, les extrémités des pieds 23 présentent un rétrécissement 24, adoptant par exemple une forme tronconique. De préférence également, les parties des pênes 18 s'étendant dans les ouvertures présentent sur leurs bords des chanfreins. Ainsi, lorsque les pieds 23 sont introduits dans les ouvertures 21 de la plate-forme 7, la coopération des pieds 23 et des pênes 18, par le glissement des surfaces de leurs bords, provoque le déplacement des pênes 18 vers leur position de déverrouillage, à l'encontre des ressorts les sollicitant. En revanche, le retrait des pieds 23 provoque le déplacement des pênes 18 vers leur position de verrouillage.The container 1 comprises feet 23, and the openings 21 of the platform 7 are adapted to receive said feet 23. Preferably, the ends of the legs 23 have a narrowing 24, adopting for example a frustoconical shape. Also preferably, the parts of the bolts 18 extending into the openings have chamfers on their edges. So when feet 23 are introduced into the openings 21 of the platform 7, the cooperation of the feet 23 and bolts 18, by the sliding of the surfaces of their edges, causes the displacement of the bolts 18 to their unlocking position, against the springs urging them. On the other hand, the withdrawal of the feet 23 causes the bolts 18 to move towards their locking position.

Les ouvertures 21 de la plate-forme 7 sont en regard des pieds 23 du conteneur 1 lorsque celui-ci est mis en place. A chaque pied 23 du conteneur 1 est associé un pêne 18 du système de verrouillage, s'étendant dans l'ouverture 21 en regard dudit pied 23. Comme ce sont les pênes 18 qui verrouillent la plate-forme 7 au cadre 16, le déverrouillage de la plate-forme 7 requiert que dans chaque ouverture 21 soit engagé un pied 23 du conteneur 1, afin de provoquer le dégagement de chaque pêne 18. Il en résulte que le déverrouillage de la plate-forme 7 par rapport au cadre 16 ne peut intervenir qu'en présence d'un conteneur 1 correctement placé. On évite ainsi tout risque d'accident dû à un déverrouillage accidentel de la plate-forme.The openings 21 of the platform 7 are opposite the feet 23 of the container 1 when it is put in place. At each foot 23 of the container 1 is associated a bolt 18 of the locking system, extending in the opening 21 opposite said foot 23. As are the bolts 18 which lock the platform 7 to the frame 16, the unlocking of the platform 7 requires that in each opening 21 is engaged a foot 23 of the container 1, to cause the release of each bolt 18. As a result, the unlocking of the platform 7 relative to the frame 16 can not intervene only in the presence of a correctly placed container 1. This avoids any risk of accident due to accidental unlocking of the platform.

En outre, comme il est prévu que l'accouplement des organes complémentaires 8,9 intervienne avant que la descente des pieds 23 du conteneur 1 ne déplace les pênes 18 en position de déverrouillage, on s'assure que le déverrouillage n'intervient qu'après l'accouplement, empêchant tout risque de chute accidentel de la plate-forme 7.In addition, as it is expected that the coupling of the complementary members 8,9 occurs before the lowering of the feet 23 of the container 1 moves the bolts 18 in the unlocked position, it is ensured that the unlocking only intervenes after mating, preventing any risk of accidental fall of the platform 7.

Comme représenté sur la figure 3, la plate-forme 7 peut comprendre sur sa périphérie des cônes de centrage 25 faisant saillie vers le haut et destiné à coopérer avec des trous de centrage 26 ouverts vers le bas ménagés dans le cadre 16, afin de guider la plate-forme 7 lors de sa remontée.As shown on the figure 3 , the platform 7 may comprise on its periphery centering cones 25 projecting upwards and intended to cooperate with downwardly open centering holes 26 formed in the frame 16, in order to guide the platform 7 during of his ascent.

L'invention sera mieux comprise en détaillant la mise en place et le retrait et d'un conteneur 1 dans la fosse 3. La figure 1 montre une vue d'ensemble de la fosse 3 dans l'espace de réception de laquelle il n'y a pas de conteneur 1. La plate-forme 7 est en position en haut de la fosse 3. La fosse 3 comporte en son fond 6 des plots d'appui 27 adaptés pour supporter le conteneur 1 lorsque la plate-forme 7 est positionnée au fond 6 de la fosse 3. Le conteneur 1 est représenté au-dessus de la plate-forme 7, en train d'être mis en place.The invention will be better understood by detailing the placement and removal and a container 1 in the pit 3. The figure 1 shows an overview of the pit 3 in the receiving space of which there is no container 1. The platform 7 is in position at the top of the pit 3. The pit 3 has in its bottom 6 support pads 27 adapted to support the container 1 when the platform 7 is positioned at the bottom 6 of the pit 3. The container 1 is shown above the platform 7, being put in place.

Le mécanisme de verrouillage 17 verrouille la plate-forme 7 au cadre 16. La figure 3 illustre un exemple d'un pêne 18 engagé dans une gâche 20 verrouillant la plate-forme 7. Plusieurs d'entre eux sont prévus sur le pourtour du cadre 16. Par exemple, dans le cas d'un cadre 16 de forme rectangulaire ou carré, quatre mécanismes de verrouillage 17 peuvent être prévus, un par coin ou par côté du cadre 16.The locking mechanism 17 locks the platform 7 to the frame 16. The figure 3 illustrates an example of a bolt 18 engaged in a strike 20 locking the platform 7. Several of them are provided on the periphery of the frame 16. For example, in the case of a frame 16 of rectangular or square shape, four locking mechanisms 17 may be provided, one per corner or one side of the frame 16.

Comme illustré sur la figure 3, les pênes 18 de la plate-forme 7 sont engagés dans les gâches 20 du cadre 16. Ils sont donc en position de verrouillage. Dans cette position, les ressorts sollicitant les pênes 18 vers leur position verrouillée subissent peu de contraintes. Les trous 22 ménagés dans les pênes 18 sont excentrés par rapport aux ouvertures ménagées dans la plate-forme 7, obturant partiellement les ouvertures 21. Plus précisément les trous ménagés dans les pênes 18 sont excentrés vers le ressort.As illustrated on the figure 3 the bolts 18 of the platform 7 are engaged in the strikers 20 of the frame 16. They are therefore in the locking position. In this position, the springs urging the bolts 18 to their locked position undergo few constraints. The holes 22 formed in the bolts 18 are eccentric with respect to the openings in the platform 7, partially closing the openings 21. More precisely, the holes in the bolts 18 are eccentric towards the spring.

Sur la figure 3, le conteneur 1 est représenté avec des pieds 23 ayant commencé à s'engager dans les ouvertures ménagées dans la plate-forme 7. Afin de faciliter l'insertion de ces pieds 23, leurs extrémités présentent de préférence un rétrécissement 24, adoptant par ici une forme tronconique. De même, les ouvertures 21 peuvent présenter un évasement vers le haut. Cela permet d'utiliser les pieds 23 pour centrer le conteneur 1 par rapport à la plate-forme 7 lors de sa descente.On the figure 3 , the container 1 is shown with feet 23 having begun to engage in the openings in the platform 7. In order to facilitate the insertion of these feet 23, their ends preferably have a narrowing 24, adopting here a frustoconical shape. Similarly, the openings 21 may have an upward flare. This allows the feet 23 to be used to center the container 1 with respect to the platform 7 during its descent.

Au fur et à mesure que le conteneur 1 descend, ces pieds 23 vont s'engager plus profondément dans les ouvertures, jusqu'à atteindre les pênes 18. La force exercée par le conteneur 1, essentiellement due au poids du conteneur 1, fait glisser les chanfreins des bords des trous 22 ménagés dans les pênes 18 par rapport aux surfaces des extrémités des pieds 23, de sorte à aligner les trous 21 des pênes 18, les ouvertures 22 de la plate-forme 7, et les pieds 23 du conteneur 1. Les pênes 18 se déplacent donc dans le sens inverse de la sollicitation du ressort de pêne 19, c'est-à-dire vers leur position de déverrouillage. Ce déplacement désengage les pênes 18 des gâches 20 du cadre 16. La plate-forme 7 n'est alors plus verrouillée au cadre 16. C'est la configuration illustrée sur la figure 4.As the container 1 goes down, these feet 23 will engage deeper into the openings, until the bolts 18 are reached. The force exerted by the container 1, essentially due to the weight of the container 1, is slippery. the chamfers of the edges of the holes 22 formed in the bolts 18 with respect to the surfaces of the ends of the feet 23, so as to align the holes 21 of the bolts 18, the openings 22 of the platform 7, and the feet 23 of the container 1 The bolts 18 therefore move in the opposite direction to the biasing of the bolt spring 19, that is to say towards their unlocking position. This movement disengages the latches 18 from the latches 20 of the frame 16. The platform 7 is then no longer locked to the frame 16. This is the configuration illustrated in FIG. figure 4 .

La figure 2 montre les organes d'accouplement 8, 9 du conteneur 1 et de la plate-forme 7 avant leur accouplement, tandis que la figure 4 montre ces organes d'accouplement 8, 9 lorsqu'ils sont accouplés.The figure 2 shows the coupling members 8, 9 of the container 1 and the platform 7 before coupling, while the figure 4 shows these coupling members 8, 9 when coupled.

Sur la figure 2, l'organe mâle 8 est en regard de l'espace d'accouplement 10 de l'organe femelle 9. La mâchoire 11 est en position fermée, obturant l'espace d'accouplement 10. Lorsque le conteneur 1 est descendu sur la plate-forme 7, l'organe mâle 8 s'insère dans l'espace d'accouplement 10. La tête 13 de l'organe mâle 8 appuie sur la mâchoire 11, exerçant sur celle-ci une force opposée à celle exercée par le ressort de rappel 14. La masse important du conteneur 1, plus de 200 kg, par exemple 650 kg, implique qu'une force importante s'exerce sur la mâchoire 11, dépassant la force de rappel du ressort, typiquement inférieure à 1000 N, par exemple de 850 N. La mâchoire 11 se déplace donc, libérant l'espace d'accouplement 10, et permettant l'insertion de l'organe mâle 8 dans l'espace d'accouplement 10.On the figure 2 , the male member 8 is opposite the coupling space 10 of the female member 9. The jaw 11 is in the closed position, closing the mating space 10. When the container 1 is lowered on the plate -form 7, the male member 8 fits into the coupling space 10. The head 13 of the male member 8 presses on the jaw 11, exerting on it a force opposite to that exerted by the return spring 14. The large mass of the container 1, more than 200 kg, for example 650 kg, implies that a significant force is exerted on the jaw 11, exceeding the restoring force of the spring, typically less than 1000 N, for example 850 N. The jaw 11 moves therefore, releasing the coupling space 10, and allowing the insertion of the male member 8 into the coupling space 10.

Comme la tête 13 de l'organe mâle 8 présente une section supérieure à la tige 12 de l'organe mâle 8, une fois la tête 13 insérée, la mâchoire 11 revient partiellement obturer l'espace d'accouplement 10. La mâchoire 11, toujours sollicitée par le ressort de rappel 14, s'oppose ainsi au retrait de la tête 13 de l'espace d'accouplement 10, et donc au désaccouplement des organes d'accouplement 8, 9. Les organes d'accouplement 8, 9 sont configurés pour résister à une force de désaccouplement supérieure au poids de la plate-forme 7, et pour se désaccoupler lorsque la force de désaccouplement dépasse un seuil de libération supérieur au poids de la plate-forme, de préférence au moins deux fois supérieur, voire au moins trois fois.As the head 13 of the male member 8 has an upper section to the rod 12 of the male member 8, once the head 13 inserted, the jaw 11 partially returns to close the mating space 10. The jaw 11, always biased by the return spring 14, thus opposes the withdrawal of the head 13 of the coupling space 10, and thus the uncoupling of the coupling members 8, 9. The coupling members 8, 9 are configured to withstand a decoupling force greater than the weight of the platform 7, and to disconnect when the uncoupling force exceeds a release threshold greater than the weight of the platform, preferably at least twice as much, or even at least three times.

Ainsi, la raideur du ressort de rappel 14 et les formes respectives de la mâchoire 11 et de l'organe mâle 8 sont choisis pour que la plate-forme 7 puisse être suspendue au conteneur 1 sans provoquer de désaccouplement. Typiquement, la plate-forme 7 présente une masse inférieure à 100 kg, par exemple de 65 kg, tandis qu'un désaccouplement requiert une force de désaccouplement supérieure à un seuil de libération de 1600 N.Thus, the stiffness of the return spring 14 and the respective shapes of the jaw 11 and the male member 8 are chosen so that the platform 7 can be suspended from the container 1 without causing disengagement. Typically, platform 7 has a mass less than 100 kg, for example 65 kg, while uncoupling requires a decoupling force greater than a release threshold of 1600 N.

La plate-forme 7 étant déverrouillée, et le conteneur 1 et la plate-forme 7 étant ainsi accouplés, la plate-forme 7 est suspendue au conteneur 1. Afin d'éviter toute chute de la plate-forme 7, les organes d'accouplement sont conçus pour que leur accouplement intervienne avant le déverrouillage des mécanismes de verrouillage 17. Par exemple, on peut prévoir qu'une course du conteneur 1 d'au moins 30 mm vers le bas par rapport à la plate-forme 7 soit nécessaire après l'accouplement des organes d'accouplement pour que les mécanismes de verrouillage 17 déverrouillent la plate-forme 7 du cadre 16. A cet effet, les organes d'accouplement 8, 9 sont de préférence configurés pour autoriser un déplacement relatif entre eux dans la direction verticale d'au moins 15 mm, et de préférence d'au moins 30 mm.The platform 7 being unlocked, and the container 1 and the platform 7 thus being coupled, the platform 7 is suspended from the container 1. In order to prevent the platform 7 from falling, the The couplings are designed so that their coupling intervenes before unlocking the locking mechanisms 17. For example, it is possible for a stroke of the container 1 to be at least 30 mm downwards with respect to the platform 7 to be necessary after the coupling of the coupling members so that the locking mechanisms 17 unlock the platform 7 of the frame 16. For this purpose, the coupling members 8, 9 are preferably configured to allow a relative movement between them in the vertical direction of at least 15 mm, and preferably at least 30 mm.

Le conteneur 1 et la plate-forme 7 suspendue audit conteneur 1 sont alors descendus dans la fosse 3. Les figures 4 et 5 montrent le conteneur 1 et la plate-forme 7 lorsqu'ils sont arrivés au fond 6 de la fosse 3.The container 1 and the platform 7 suspended to said container 1 are then lowered into the pit 3. The figures 4 and 5 show the container 1 and the platform 7 when they arrived at the bottom 6 of the pit 3.

La plate-forme 7 est positionnée au fond 6 de la fosse 3, et plus précisément entre ledit fond 6 et le conteneur 1. La plate-forme 7 comporte des passages adaptés pour permettre au conteneur 1 de reposer sur le fond 6 de la fosse 3 lorsque plate-forme 7 est positionnée au fond 6 de la fosse 3. Plus précisément, la fosse 3 et/ou le conteneur 1 peut comprendre des plots d'appui, et des passages 28 sont ménagés dans la plate-forme 7, à travers lesquels passent les plots d'appui 27.The platform 7 is positioned at the bottom 6 of the pit 3, and more precisely between said bottom 6 and the container 1. The platform 7 has passages adapted to allow the container 1 to rest on the bottom 6 of the pit 3 when platform 7 is positioned at the bottom 6 of the pit 3. More specifically, the pit 3 and / or the container 1 may comprise bearing pads, and passages 28 are formed in the platform 7, to through which the support pads pass 27.

Ces plots d'appui 27 permettent de faire reposer le conteneur 1, non sur la plate-forme 7, mais sur le fond 6 de la fosse 3, par l'intermédiaire desdits plots d'appui 27. De préférence, les plots d'appui 27 sont positionnés au niveau des portes du conteneur 1, ce qui permet de s'assurer de la fermeture.These support pads 27 make it possible to rest the container 1, not on the platform 7, but on the bottom 6 of the pit 3, by means of said bearing pads 27. Preferably, the pads of support 27 are positioned at the container doors 1, which ensures the closure.

La plate-forme 7 n'est plus suspendue au conteneur 1, bien qu'elle y soit accouplée. Des appuis sont prévus pour surélever la plate-forme 7 par rapport à sa position de suspension, laquelle correspondait à des organes d'accouplement 8, 9 dans leur extrémité basse de leur course libre. Ces appuis peuvent être, comme sur les figures 4 et 5, les plots d'appui 27, lesquels présentant une section s'élargissant vers le bas, supporte la plate-forme 7 à une hauteur où cette section devient supérieure à celle des passages 28. Ces appuis pourraient être également des appuis dédiés au fond 6 de la fosse 3, ne traversant pas la plate-forme 7.The platform 7 is no longer suspended from the container 1, although it is coupled therewith. Supports are provided to raise the platform 7 relative to its suspension position, which corresponded to coupling members 8, 9 in their lower end of their free stroke. These supports can be, as on the figures 4 and 5 , the bearing pads 27, which have a section widening downwards, supports the platform 7 at a height where this section becomes greater than that of the passages 28. These supports could also be supports dedicated to the bottom 6 of the pit 3, not crossing the platform 7.

Ainsi, lors de la descente du conteneur 1 et de la plate-forme 7 au fond 6 de la fosse 3, la plate-forme 7 vient d'abord reposer sur les appuis au fond 6 de la fosse 3. La course libre des organes d'accouplement 8, 9 permet ensuite de continuer la descente du conteneur 1 pour le faire reposer sur les plots d'appui 27. Les hauteurs respectives des positions de la plate-forme 7 et du conteneur 1 sont choisies pour que les pieds 23 du conteneur 1 se retirent suffisamment des ouvertures 21 pour permettre aux pênes 18 reprendre une position de verrouillage, dans laquelle le ressort de pêne n'est pas sollicité. Le retrait des pieds 23 peut ne pas être total, comme illustré dans les figures, où cependant la section décroissante des pieds 23 au niveau de leur rétrécissement 24 fait que leur déplacement vers le haut par rapport à la plate-forme 7 autorise un déplacement des pênes 18 vers leurs positions de verrouillage.Thus, during the descent of the container 1 and the platform 7 at the bottom 6 of the pit 3, the platform 7 is first rest on the supports at the bottom 6 of the pit 3. The free movement of the organs 8, 9 allows then to continue the descent of the container 1 to rest on the support pads 27. The respective heights of the positions of the platform 7 and the container 1 are chosen so that the feet 23 of the container 1 withdraw sufficiently from the openings 21 to allow the bolts 18 to resume a locking position, in which the bolt spring is not biased. The withdrawal of the feet 23 may not be total, as shown in the figures, where however the decreasing section of the feet 23 at their narrowing 24 makes their upward movement relative to the platform 7 allows a movement of bolts 18 to their locking positions.

Le conteneur 1 n'étant sorti de la fosse 3 que pour être vidé et étant remis en place immédiatement après, la configuration dans laquelle la plate-forme 7 et le conteneur 1 sont au fond 6 de la fosse 3 représente la configuration habituelle, pour plus de 99% du temps. Dans cette configuration, contrairement à l'état de la technique, aucun élément du système d'accouplement ou de verrouillage ne subit de contrainte. Le vieillissement et l'usure de l'ensemble est donc fortement réduit.Since the container 1 has only left the pit 3 to be emptied and replaced immediately afterwards, the configuration in which the platform 7 and the container 1 are at the bottom 6 of the pit 3 represents the usual configuration for more than 99% of the time. In this configuration, unlike the state of the art, no part of the coupling or locking system is constrained. Aging and wear of the whole is therefore greatly reduced.

Pour retirer le conteneur 1, celui-ci est soulevé verticalement. Les organes d'accouplement 8, 9, toujours accouplés, de déplacent l'un par rapport à l'autre sur leur course libre. Plus précisément, la tête 13 de l'organe mâle 8 remonte dans l'espace d'accouplement 10 jusqu'à entrer en contact avec la mâchoire 11. Le seul poids de la plate-forme 7 n'étant pas suffisant à vaincre la force de rappel exercée par le ressort de rappel 14, les organes restent accouplés. La plate-forme 7 se retrouve suspendue au conteneur 1, et soulevé avec lui.To remove the container 1, it is lifted vertically. The coupling members 8, 9, always coupled, move relative to each other on their free stroke. More specifically, the head 13 of the male member 8 rises in the coupling space 10 until it comes into contact with the jaw 11. The sole weight of the platform 7 is not sufficient to overcome the force restoring force exerted by the return spring 14, the organs remain coupled. The platform 7 is suspended from the container 1, and raised with him.

Le conteneur 1 et la plate-forme 7 qui lui est suspendue remonte jusqu'à ce que la plate-forme 7 atteigne le haut 5 de la fosse 3. Les cônes de centrage 25 de la plate-forme 7 s'engagent dans les trous de centrage 26 du cadre 16, guidant la plate-forme 7 lors de la partie finale de sa remontée. La remontée de la plate-forme 7 est arrêtée par le cadre 16. La plate-forme 7 est alors dans sa position en haut 5 de la fosse 3.The container 1 and the platform 7 which is suspended up to it until the platform 7 reaches the top 5 of the pit 3. The centering cones 25 of the platform 7 engage in the holes centering 26 of the frame 16, guiding the platform 7 during the final part of its ascent. The raising of the platform 7 is stopped by the frame 16. The platform 7 is then in its position at the top 5 of the pit 3.

Le conteneur 1 continuant d'être remonté, les pieds 23 se désengagent complètement des ouvertures de la plate-forme 7, permettant aux pênes 18 de se déplacer entre la position de verrouillage et la position de déverrouillage. Les chanfreins aux extrémités des pênes 18 permettent aux pênes 18 de se rétracter en position de déverrouillage à l'approche des gâches 20, lorsque les pênes 18 appuient sur le cadre 16. Arrivé en regard des gâches 20, les pênes 18 s'étendent dans leur position de verrouillage, de façon similaire à la fermeture d'une porte. La plate-forme 7 est alors verrouillée au cadre 16. On retrouve la configuration illustrée par la figure 3.As the container 1 continues to be reassembled, the feet 23 completely disengage from the openings of the platform 7, allowing the bolts 18 to move between the locking position and the unlocking position. The chamfers at the ends of the bolts 18 allow the bolts 18 to retract into the unlocked position at the approach of the strikes 20, when the bolts 18 rest on the frame 16. Arrived opposite the strikers 20, the bolts 18 extend into their locking position, similar to the closing of a door. The platform 7 is then locked to the frame 16. We find the configuration illustrated by the figure 3 .

Le conteneur 1 continue, mais la plate-forme 7 est désormais verrouillée au cadre 16, et ne remonte donc plus. La force de désaccouplement s'exerçant sur les organes d'accouplement 8,9 dépasse alors le poids de la plate-forme 7, et atteint le seuil de libération au-delà duquel la force de rappel exercée par le ressort de rappel 14 ne permet pas à la mâchoire 11 de rester en position fermée. La mâchoire 11 pivote donc, libérant la sortie de l'espace d'accouplement 10. La tête 13 de l'organe mâle 8 se dégage alors de l'espace d'accouplement 10. Les organes d'accouplement sont alors découplés. La mâchoire 11 reprend ensuite sa position fermée. On retrouve la configuration illustrée par la figure 2. Le conteneur 1 est alors sorti de la fosse 3 et désolidarisé de la plate-forme 7. On retrouve donc la configuration illustrée par la figure 1.The container 1 continues, but the platform 7 is now locked to the frame 16, and therefore no longer goes up. The uncoupling force exerted on the coupling members 8, 9 then exceeds the weight of the platform 7, and reaches the release threshold beyond which the restoring force exerted by the return spring 14 does not allow not to the jaw 11 to remain in closed position. The jaw 11 pivots, releasing the output of the coupling space 10. The head 13 of the male member 8 then emerges from the coupling space 10. The coupling members are then decoupled. The jaw 11 then resumes its closed position. We find the configuration illustrated by the figure 2 . The container 1 is then released from the pit 3 and disengaged from the platform 7. There is therefore the configuration illustrated by the figure 1 .
