Description

L'invention a trait à un dispositif de connexion étanche entre deux enceintes.The invention relates to a device for sealing connection between two enclosures.

Le terme enceinte désigne ici un dispositif ou un récipient équipé d'un moyen d'accès obturable de manière étanche. Ce récipient ou dispositif définit un volume de préparation, de stockage et/ou de manipulation de produits ne devant pas être en contact avec l'extérieur ou avec un utilisateur. Il s'agit par exemple de produits dits dangereux comme certains produits biologiques, chimiques ou radioactifs. De telles enceintes, dites de manipulation, permettent de réaliser certaines manipulations sur ces produits sans que le manipulateur ait un contact direct avec les produits. La manipulation s'effectue par l'intermédiaire d'outils ou de gants fixés sur l'enceinte. Les manipulations des produits sont ainsi réalisées en isolant l'enceinte de l'extérieur.The term "enclosure" here designates a device or a container equipped with an access means that can be sealed off. This container or device defines a volume of preparation, storage and / or manipulation of products not to be in contact with the outside or with a user. These are, for example, so-called hazardous products such as certain biological, chemical or radioactive products. Such speakers, called manipulation, allow to perform certain manipulations on these products without the manipulator has direct contact with the products. Handling is carried out by means of tools or gloves attached to the enclosure. The manipulations of the products are thus achieved by isolating the enclosure from the outside.

Il convient, pour certaines manipulations, de connecter de manière étanche deux enceintes entre elles. Cette connexion s'effectue en préservant la stérilité d'au moins une des deux enceintes, sans contact direct avec l'extérieur.It is appropriate, for some manipulations, to connect tightly two speakers between them. This connection is made by preserving the sterility of at least one of the two speakers, without direct contact with the outside.

Une des enceintes connectées peut, par exemple, être un récipient de collecte des déchets, de type container. Au moins une des enceintes est apte à être stérilisée.One of the connected speakers may, for example, be a waste collection container type container. At least one of the enclosures is capable of being sterilized.

Afin d'accéder à l'intérieur d'une enceinte de manipulation, celle-ci est munie d'au moins une ouverture équipée d'une porte étanche. Cette porte est généralement manoeuvrable par l'utilisateur à partir de l'intérieur de l'enceinte. Il convient, lorsque l'on souhaite connecter deux enceintes, de même type ou de types différents, d'assurer une liaison évitant toute pollution d'une des enceintes par l'autre ou par l'extérieur. Pour cela, il est connu de connecter les portes des deux enceintes de manière jointive en isolant un matelas d'air, minimal, entre les deux portes connectées.In order to access the inside of a handling enclosure, it is provided with at least one opening equipped with a sealed door. This door is generally maneuverable by the user from inside the enclosure. It is appropriate, when it is desired to connect two speakers, of the same type or of different types, to ensure a connection avoiding any pollution of one of the speakers by the other or by the outside. For this, it is known to connect the doors of the two enclosures contiguously by isolating a minimum air mattress between the two connected doors.

La stérilité de l'enceinte doit également être préservée lorsque l'on connecte une enceinte de manipulation à un récipient de type container à déchets pour évacuer certains produits hors de l'enceinte.The sterility of the enclosure must also be preserved when connecting a handling chamber to a waste container container to evacuate certain products outside the enclosure.

Par EP-A-688 020 , on connaît un dispositif de jonction étanche entre une enceinte de manipulation et une enceinte à usage unique. L'enceinte à usage unique comprend une porte dont le verrouillage est commandé par des moyens installés dans l'enceinte de manipulation. Les deux enceintes sont reliées au moyen de brides annulaires entourant leurs portes respectives. La solidarisation a lieu au moyen de plaquettes magnétiques ou de ventouses, de manière à assembler par simple contact les portes des enceintes. Des câbles actionnés par un levier permettent de retirer simultanément les portes ainsi solidarisées. Ceci permet de dégager une ouverture autorisant le passage d'une enceinte à l'autre.By EP-A-688 020 , there is known a sealed junction device between a handling chamber and a disposable enclosure. The disposable enclosure comprises a door whose locking is controlled by means installed in the handling chamber. The two enclosures are connected by means of annular flanges surrounding their respective doors. The securing takes place by means of magnetic pads or suction cups, so as to assemble by simple contact the speaker doors. Cables operated by a lever can simultaneously remove the doors and secured. This allows to release an opening allowing the passage of a speaker to another.

On connaît également, par FR-A-2 695 343 , un dispositif de transfert étanche entre deux enceintes. Ce dispositif comprend au moins un organe de commande mobile intégrant quatre verrous. Deux de ces verrous empêchent toute manoeuvre d'ouverture tant que les portes des enceintes ne sont pas en contact mutuel. Un troisième verrou empêche la déconnection des deux enceintes lorsqu'elles sont connectées par leurs brides respectives. Un quatrième verrou empêche tout mouvement de l'organe de commande lorsque les portes sont ouvertes.We also know, by FR-A-2,695,343 , a waterproof transfer device between two enclosures. This device comprises at least one movable control member incorporating four locks. Two of these locks prevent any opening maneuver as long as the speaker doors are not in contact with each other. A third latch prevents disconnection of both speakers when connected by their respective flanges. A fourth latch prevents any movement of the controller when the doors are open.

On connaît également, par FR-A-2 496 325 , un dispositif de connexion entre deux enceintes, pourvu d'organes de sécurité évitant certaines fausses manoeuvres telles que l'ouverture de la porte d'une enceinte en l'absence de l'autre enceinte. Pour cela, le dispositif comporte plusieurs verrous situés sur une enceinte, associés à des moyens de détection sensibles à la présence d'une deuxième enceinte pour autoriser l'ouverture des portes des enceintes. Ces moyens de détection sont formés par des microrupteurs et les verrous sont de type électrique.We also know, by FR-A-2,496,325 , a connection device between two enclosures, provided with safety devices avoiding certain false maneuvers such as the opening of the door of an enclosure in the absence of the other enclosure. For this, the device comprises several locks located on a speaker, associated with detection means responsive to the presence of a second speaker to allow the opening of the speaker doors. These detection means are formed by microswitches and the locks are of the electric type.

GB-A-2 109 719 décrit un dispositif de connexion entre deux enceintes comprenant une plaque, montée sur une porte pivotante d'une enceinte, et adaptée pour coopérer avec une plaque fixe montée sur un anneau fixé sur l'ouverture d'une autre enceinte. Une barre de manoeuvre permet de faire tourner la plaque pour qu'elle coopère avec des logements situés sur l'autre enceinte. Une seule manoeuvre assure la liaison des enceintes et la connexion des portes. GB-A-2,109,719 discloses a connection device between two enclosures comprising a plate, mounted on a pivoting door of an enclosure, and adapted to cooperate with a fixed plate mounted on a ring fixed on the opening of another enclosure. An operating bar allows the plate to rotate so that it cooperates with housings located on the other pregnant. A single maneuver ensures the connection of the speakers and the connection of the doors.

Par GB-A-2 218 663 on connaît un dispositif de connexion comprenant trois bras articulés, disposés en triangle et montés rotatifs sur une porte d'une enceinte. Sur l'autre enceinte, la porte est équipée de bras fixes, disposés en étoile, manoeuvrés conjointement aux bras articulés lorsque les enceintes sont connectées. Le dispositif comprend également un organe de sécurité évitant l'ouverture de la porte lorsque les enceintes ne sont pas connectées.By GB-A-2 218 663 a connection device is known comprising three articulated arms, arranged in a triangle and rotatably mounted on a door of an enclosure. On the other speaker, the door is equipped with fixed arms, arranged in star, manipulated together with the articulated arms when the speakers are connected. The device also comprises a safety member avoiding the opening of the door when the speakers are not connected.

Ces différents dispositifs de connexion permettent, par des manoeuvres plus ou moins complexes, de connecter une enceinte à une autre enceinte avec des dispositifs de sécurité évitant certaines fausses manoeuvres de la part de l'utilisateur.These different connection devices allow, by more or less complex maneuvers, to connect an enclosure to another enclosure with safety devices avoiding certain false maneuvers on the part of the user.

L'invention se propose de réaliser un autre dispositif de connexion entre deux enceintes, simple, aisé à fabriquer et à manoeuvrer, permettant la connexion de deux enceintes puis la solidarisation et l'ouverture des portes, tout en préservant la stérilité des enceintes.The invention proposes to make another connection device between two speakers, simple, easy to manufacture and operate, allowing the connection of two speakers and the joining and opening of the doors, while preserving the sterility of the speakers.

A cet effet, l'invention a pour objet un dispositif de connexion étanche entre deux enceintes, équipées chacune d'au moins une porte, comprenant des moyens de connexion des enceintes et des moyens de solidarisation des portes des enceintes, les moyens de solidarisation des portes comprenant, sur une porte d'une première enceinte, un organe de liaison en relief, de forme prédéfinie et mobile en rotation, adapté pour coopérer avec un organe de liaison en relief, fixe et de forme complémentaire à celle de l'organe de liaison mobile, situé sur une porte d'une seconde enceinte, caractérisé en ce que la porte d'une enceinte est pourvue d'au moins une barre de blocage verrouillant son ouverture et montée sur un support fixé sur l'organe de liaison, le support étant mobile en translation, sous l'action de la rotation de l'organe de liaison, dans une fente configurée en arc de cercle et ménagée dans la porte.For this purpose, the subject of the invention is a device for sealing connection between two enclosures, each equipped with at least one door, comprising means for connecting the enclosures and means for securing the doors of the enclosures, the means for securing the doors comprising, on a door of a first enclosure, a relief connecting member, of predefined shape and movable in rotation, adapted to cooperate with a relief connecting element, fixed and of complementary shape to that of the body of mobile connection, located on a door of a second enclosure, characterized in that the door of an enclosure is provided with at least one locking bar locking its opening and mounted on a support fixed on the connecting member, the support being movable in translation, under the action of the rotation of the connecting member, in a slot configured in an arc and formed in the door.

La présence d'organes de liaison de formes complémentaires, sur chacune des portes permet, d'une part, de guider les portes lors de la connexion, et, d'autre part, d'éviter de solidariser deux enceintes non adaptées l'une à l'autre. En d'autres termes, chacune des portes d'une enceinte conforme à l'invention ne peut être solidarisée et ouverte, qu'avec une porte d'une enceinte complémentaire. Avec un tel dispositif l'ouverture et la fermeture des portes des enceintes ne peuvent avoir lieu que lorsque les enceintes prédéfinies sont connectées. En effet, il n'est pas possible de connecter entre elles des enceintes, et donc encore moins de solidariser les portes et de les manoeuvrer, si les enceintes n'ont pas d'organes de liaison de formes complémentaires.The presence of connecting members of complementary shapes on each of the doors makes it possible, on the one hand, to guide the doors during the connection, and, on the other hand, to avoid joining two non-adapted enclosures together. to the other. In other words, each of the doors of a compliant enclosure to the invention can be secured and open, with a door of a complementary enclosure. With such a device the opening and closing of the speaker doors can only take place when the predefined speakers are connected. Indeed, it is not possible to connect together the speakers, and therefore even less to secure the doors and maneuver, if the speakers do not have connecting members of complementary shapes.

Selon des aspects avantageux mais non obligatoires de l'invention, le dispositif peut incorporer une ou plusieurs des caractéristiques suivantes :

  • Deux barres de blocage sont montées sur deux supports fixés sur l'organe de liaison, ces supports étant mobiles chacun en translation, dans une fente.
  • Les barres de blocage sont de longueurs adaptées pour être mobiles en translation dans des logements ménagés dans la porte et dans des logements ménagés dans la paroi de l'enceinte, les logements étant dans le prolongement les uns des autres lorsque la porte est fermée.
  • L'organe de liaison d'une porte est une empreinte centrale qui reproduit, en positif, une forme géométrique et/ou un code alphanumérique, alors que l'organe de liaison de l'autre porte est une empreinte centrale qui reproduit cette forme géométrique et/ou ce code alphanumérique en négatif.
  • Les moyens de connexion des enceintes comprennent des brides de formes complémentaires formant un dispositif de connexion de type à baïonnette.
  • Les moyens de solidarisation des portes comprennent des brides de formes complémentaires formant un dispositif de solidarisation de type à baïonnette.
  • Une enceinte est équipée d'un organe de sécurité interdisant la désolidarisation des enceintes lorsque la porte de cette enceinte est ouverte, cet organe de sécurité étant adapté pour passer d'une première position interdisant l'ouverture de la porte d'une enceinte, lorsque celle-ci n'est pas reliée à une autre enceinte, à une seconde position autorisant l'ouverture de la porte lorsque les enceintes sont connectées.
  • L'organe de sécurité est mobile en rotation et équipé d'un logement de réception, à profondeur variable, d'un organe de blocage lui-même mobile en translation.
According to advantageous but not obligatory aspects of the invention, the device may incorporate one or more of the following features:
  • Two locking bars are mounted on two supports fixed on the connecting member, these supports being each movable in translation, in a slot.
  • The locking bars are of lengths adapted to be movable in translation in housings formed in the door and in housings formed in the wall of the enclosure, the housing being in the extension of each other when the door is closed.
  • The connecting member of a door is a central imprint that reproduces, in positive, a geometric shape and / or an alphanumeric code, while the connecting member of the other door is a central imprint that reproduces this geometric shape and / or this alphanumeric code in negative.
  • The speaker connection means comprise flanges of complementary shapes forming a bayonet type connection device.
  • The means for securing the doors comprise flanges of complementary shapes forming a bayonet-type fastening device.
  • An enclosure is equipped with a safety device preventing the detachment of the speakers when the door of this enclosure is open, this safety member being adapted to move from a first position prohibiting the opening of the door of an enclosure, when it is not connected to another speaker, to a second position allowing the opening of the door when the speakers are connected.
  • The safety member is rotatable and equipped with a receiving housing, with variable depth, a locking member itself movable in translation.

L'invention sera mieux comprise et d'autres avantages de celle-ci apparaîtront plus clairement à la lecture de la description qui va suivre d'un mode de réalisation d'un dispositif conforme à l'invention, donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés dans lesquels :

The invention will be better understood and other advantages thereof will appear more clearly on reading the following description of an embodiment of a device according to the invention, given solely by way of example. and with reference to the accompanying drawings in which:
  • the figure 1 is a top view of a first type of enclosure equipped with a door belonging to a device according to the invention,

  • the figures 8 , 9 and 10 are sections, respectively along the lines AA, CC and DD at the figure 7 and at other scales, when the door is in place on the second enclosure, the latter being also shown.

La figure 1 représente un premier type d'enceinte. Cette enceinte 1 est équipée d'une porte ou couvercle 2, qui est vu de dessus sur cette figure. Dans l'exemple, cette première enceinte est un container 1 à section carrée. De tels containers sont réalisés en matériau rigide. Ils permettent la collecte, le stockage et le transport de déchets potentiellement dangereux, tels que des déchets d'origine biologique ou chimique.The figure 1 represents a first type of enclosure. This enclosure 1 is equipped with a door or cover 2, which is seen from above in this figure. In the example, this first enclosure is a container 1 with a square section. Such containers are made of rigid material. They allow the collection, storage and transport of potentially hazardous waste, such as biological or chemical waste.

Le col 3 de ce container 1, illustré à la figure 3, reçoit un manchon interne 3' pourvu d'un bord périphérique 4, continu et s'étendant radialement vers l'extérieur. Ce bord définit donc une lèvre circulaire 4 continue. L'extrémité libre de cette lèvre 4 est repliée vers l'intérieur, en formant une gorge 4' visible par exemple à la figure 6.Collar 3 of this container 1, shown in FIG. figure 3 , receives an inner sleeve 3 'provided with a peripheral edge 4, continuous and extending radially outwardly. This edge therefore defines a continuous circular lip 4. The free end of this lip 4 is folded inwards, forming a groove 4 'visible for example at the figure 6 .

La lèvre 4 définit une première bride périphérique 5, annulaire et fixée sur le col 3. Cette bride 5 est pourvue de pattes 6 s'étendant radialement vers l'extérieur à partir de la périphérie de la bride 5, comme illustrée aux figures 1 et 3.The lip 4 defines a first peripheral flange 5, annular and fixed on the neck 3. This flange 5 is provided with tabs 6 extending radially outwardly from the periphery of the flange 5, as illustrated in FIGS. figures 1 and 3 .

En position fermée sur ce col 3, le couvercle 2 est configuré en relief s'étendant vers l'intérieur du container 1, tel que représenté aux figures 1, 3 à 5. La partie intérieure centrale 7 du couvercle 2 est d'un diamètre légèrement inférieur au diamètre intérieur du manchon 3. De cette manière, la partie 7 s'insère dans le col 3 et obture ce dernier de façon étanche grâce à un joint annulaire 8, visible aux figures 8 à 10 et inséré dans la gorge 4'. Cette partie intérieure 7 est en creux par rapport à un plan P tangent à une face supérieure de la bride 5, comme illustré à la figure 3.In the closed position on this neck 3, the cover 2 is configured in relief extending inwardly of the container 1, as shown in FIGS. Figures 1, 3 to 5 . The central inner part 7 of the lid 2 is of a diameter slightly smaller than the inside diameter of the sleeve 3. In this way, the part 7 fits into the neck 3 and closes the latter tightly thanks to an annular seal 8, visible to Figures 8 to 10 and inserted into the groove 4 '. This inner portion 7 is recessed relative to a plane P tangential to an upper face of the flange 5, as illustrated in FIG. figure 3 .

La partie 7 comporte un bord supérieur annulaire conformé en une bride périphérique 9 dirigée vers le centre du couvercle 2. Cette bride 9 est parallèle au plan P et située sensiblement au niveau de la lèvre 4. La bride 9 est concentrique avec la bride 5. La bride périphérique 9 est régulièrement pourvue d'encoches 10 et de pattes 10' permettant un accès à l'espace disponible entre la bride 9 et le fond 11 de la partie intérieure 7 du couvercle 2. La bride 9 est adaptée pour que sa périphérie extérieure, continue, soit en appui étanche contre le joint 8.The portion 7 comprises an annular upper edge shaped as a peripheral flange 9 directed towards the center of the lid 2. This flange 9 is parallel to the plane P and located substantially at the level of the lip 4. The flange 9 is concentric with the flange 5. The peripheral flange 9 is regularly provided with notches 10 and lugs 10 'allowing access to the available space between the flange 9 and the bottom 11 of the inner part 7 of the cover 2. The flange 9 is adapted so that its periphery external, continuous, or in sealing support against the gasket 8.

Le fond 11 du couvercle 2 est équipé en partie centrale, d'un organe de liaison ou empreinte 12 en relief. En l'occurrence, cette empreinte 12 reproduit le nom de la demanderesse avec un graphisme particulier. En l'espèce, cette empreinte 12 comprend un code alphanumérique 121 et une nervure périphérique 122. En variante, il peut s'agir d'une autre forme géométrique, par exemple un motif décoratif. Cette empreinte 12 en relief s'étend en saillie à partir du fond 11 en direction du plan P. Elle forme ainsi un organe de liaison 12 de géométrie prédéfinie.The bottom 11 of the lid 2 is equipped in the central part, with a connecting member or embossment 12 in relief. In this case, this imprint 12 reproduces the name of the applicant with a particular graphic. In this case, this imprint 12 comprises an alphanumeric code 121 and a peripheral rib 122. Alternatively, it may be another geometric shape, for example a decorative pattern. This relief 12 protrudes protruding from the bottom 11 in the direction of the plane P. It thus forms a connecting member 12 of predefined geometry.

Les brides 5 et 9 définissent deux systèmes de connexion de type à baïonnette, connus en soi. Ces systèmes sont concentriques. La bride 5 est orientée vers l'extérieur du col 3 et permet une connexion de ce dernier avec une enceinte autre que le container 1. L'autre bride 9 est orientée vers l'intérieur du col 3 et permet la connexion du couvercle 2 avec une porte de l'enceinte.Flanges 5 and 9 define two bayonet type connection systems, known per se. These systems are concentric. The flange 5 is oriented towards the outside of the neck 3 and allows a connection of the latter with an enclosure other than the container 1. The other flange 9 is oriented towards the inside of the neck 3 and allows the connection of the cover 2 with a door of the enclosure.

Le maintien en position verrouillée du couvercle 2 à l'intérieur du col 3, lorsque le container 1 est dans une position, illustrée à la figure 4, où il n'est pas connecté à une autre enceinte, est assuré par la partie intérieure 7. Cette partie 7 est pourvue, sur son bord extérieur, d'ergots. Un ergot 13 est partiellement visible à la figure 6. Plusieurs ergots 13 s'étendent radialement vers l'extérieur de la partie 7 et sont répartis sur sa périphérie. Ces ergots 13 sont insérés dans des fentes 14 visibles notamment à la figure 6 lorsque le couvercle est verrouillé dans le col 3. Les fentes 14 sont ménagées dans la paroi du manchon 3'. Ces fentes 14 sont configurées en L. La grande branche 140 de chaque fente 14 est située à proximité du haut du col 3 et orientée parallèlement au plan P. Ces fentes 14 permettent la réception des ergots 13 dans les petites branches 141 des fentes 14 qui sont orientées selon une direction parallèle à un axe longitudinal A-A' du container.Keeping the lid 2 in the locked position inside the neck 3, when the container 1 is in a position, illustrated in FIG. figure 4 , where it is not connected to another enclosure, is provided by the inner portion 7. This portion 7 is provided on its outer edge, pins. A pin 13 is partially visible at the figure 6 . Several lugs 13 extend radially outwardly of the portion 7 and are distributed on its periphery. These lugs 13 are inserted in slots 14 visible in particular at the figure 6 when the lid is locked in the neck 3. The slots 14 are formed in the wall of the sleeve 3 '. These slots 14 are configured in L. The large branch 140 of each slot 14 is located near the top of the neck 3 and oriented parallel to the plane P. These slots 14 allow the reception of the lugs 13 in the small branches 141 of the slots 14 which are oriented in a direction parallel to a longitudinal axis AA 'of the container.

Lors de la mise en place du couvercle 2 dans le col 3, il convient de positionner les ergots 13 en face de l'extrémité libre de la petite branche 141 des fentes 14. Ceci est facilité par des guides 14' situés entre deux fentes 14. Ainsi, on réalise un guidage du couvercle 2 préalablement à son verrouillage. Lorsqu'on a inséré les ergots 13 dans la partie 141 des fentes, on tourne le couvercle 2, dans le sens des aiguilles d'une montre à la figure 1. Chaque ergot 13 se déplace en direction de l'extrémité libre de la grande branche 140 en L de la fente 14 qui le reçoit. Cette branche 140 s'étendant perpendiculairement à l'axe longitudinal A-A' du container 1, le couvercle 2 est alors verrouillé, en position fermée, sur le col 3. Pour réaliser ce mouvement de rotation, il convient que le couvercle 2 soit équipé d'un organe de préhension. La seule partie du couvercle 2 permettant la préhension et la manoeuvre du couvercle 2 est formée par l'empreinte centrale 12.When placing the cover 2 in the neck 3, it is necessary to position the lugs 13 opposite the free end of the small branch 141 of the slots 14. This is facilitated by guides 14 'located between two slots 14 Thus, a guiding of the lid 2 is carried out prior to locking it. When the lugs 13 are inserted in the slot portion 141, the cover 2 is rotated clockwise at the figure 1 . Each lug 13 moves towards the free end of the large branch 140 L of the slot 14 which receives it. This branch 140 extending perpendicular to the longitudinal axis AA 'of the container 1, the lid 2 is then locked, in the closed position, on the neck 3. To achieve this rotational movement, it is appropriate that the lid 2 is equipped with a grasping organ. The only part of the cover 2 for gripping and actuating the cover 2 is formed by the central recess 12.

Compte tenu de la forme particulière de cette empreinte 12, la manoeuvre du couvercle 2 ne peut pas être aisément réalisée manuellement ou à l'aide d'un outil habituellement disponible, par exemple une pince ou un tournevis. Pour assurer la manoeuvre du couvercle 2, il est nécessaire de disposer d'un organe de liaison ou empreinte 15, de forme complémentaire à celle de l'empreinte 12, dont les reliefs et les creux vont coopérer avec les creux et les reliefs de l'empreinte 12 du couvercle 2 afin de pouvoir manoeuvrer celui-ci. Un tel organe de liaison 15 de forme complémentaire est représenté à la figure 2, en partie centrale de la porte 16 d'une enceinte 17. Ainsi, l'empreinte 15 comprend un motif alphanumérique 151 de forme complémentaire au motif 121 et un bord 152 complémentaire du bord interne de la nervure 122.Given the particular shape of this cavity 12, the operation of the lid 2 can not be easily performed manually or with a tool usually available, for example a clamp or a screwdriver. To ensure the operation of the lid 2, it is necessary to have a connecting member or impression 15, complementary in shape to that of the cavity 12, the reliefs and recesses will cooperate with the recesses and reliefs of the cavity 12 of the cover 2 in order to be able to maneuver it. Such a connecting member 15 of complementary shape is shown in FIG. figure 2 , in the central part of the door 16 of an enclosure 17. Thus, the impression 15 comprises an alphanumeric pattern 151 of complementary shape to the pattern 121 and a complementary edge 152 of the inner edge of the rib 122.

Cette porte 16 équipe une paroi 170 d'une enceinte 17, telle que schématiquement représentée à la figure 2. De telles enceintes 17 sont connues en soi. Elles peuvent être pourvues de plusieurs portes 16 équipées chacune d'une même empreinte 15. En variante, une même enceinte 17 peut être équipée de plusieurs portes 16, chaque porte 16 ayant une empreinte 15 spécifique adaptée à la connexion avec un type de récipient. Pour la clarté de l'exposé et la lisibilité des figures, seule la porte 16 est représentée aux figures 3 à 10.This door 16 equips a wall 170 of an enclosure 17, as schematically represented in FIG. figure 2 . Such enclosures 17 are known per se. They can be provided with several doors 16 each equipped with the same footprint 15. In a variant, the same enclosure 17 can be equipped with several doors 16, each door 16 having a specific footprint 15 adapted to the connection with a type of receptacle. For the clarity of the presentation and the readability of the figures, only the door 16 is shown in FIGS. Figures 3 to 10 .

Il est également possible d'utiliser d'un outil, par exemple un outil à main, équipé d'une extrémité pourvue d'une empreinte 15 de forme complémentaire à celle de l'empreinte 12 située sur le couvercle 2. Un tel outil permet, si besoin, l'ouverture et la fermeture du container 1, pour certaines opérations de maintenance ou de nettoyage du container 1. Il n'en demeure pas moins que le couvercle 2 du container 1 doit, pour pouvoir être manoeuvré, être relié à un dispositif pourvu d'une empreinte 15 de forme complémentaire à celle de l'empreinte 12 présente sur le couvercle 2.It is also possible to use a tool, for example a hand tool, equipped with an end provided with a recess 15 complementary to that of the cavity 12 located on the lid 2. Such a tool allows , if necessary, the opening and closing of the container 1, for certain maintenance or cleaning operations of the container 1. The fact remains that the lid 2 of the container 1 must, in order to be manoeuvrable, be connected to a device provided with a recess 15 of complementary shape to that of the imprint 12 present on the lid 2.

La porte 16, illustrée à la figure 2, a une forme complémentaire au couvercle 2 du container 1 illustré à la figure 1. L'emplacement de la porte 16 dans la paroi 170 est délimitée par une bride 18, annulaire, fixée sur la paroi 170 de l'enceinte 17 et parallèle à un plan principal P' de la porte 16 représenté à la figure 3 et qui est tangent à une face extérieure de la paroi 170 lorsque la porte 16 est fermée.The door 16, illustrated at figure 2 has a shape complementary to the lid 2 of the container 1 illustrated in FIG. figure 1 . The location of the door 16 in the wall 170 is delimited by a flange 18, annular, fixed on the wall 170 of the enclosure 17 and parallel to a main plane P 'of the door 16 shown in FIG. figure 3 and which is tangent to an outer face of the wall 170 when the door 16 is closed.

Cette bride 18 est équipée d'encoches 19 qui ménagent ainsi, entre la bride 18 et la paroi 170, un espace adapté pour recevoir les pattes 6, de la bride extérieure 5 du couvercle 2. On réalise ainsi un système de connexion mutuelle, de type à baïonnette, entre l'enceinte 17 et le container 1. Cette première connexion permet de solidariser les enceintes indépendamment d'une seconde connexion entre la porte 16 et le couvercle 2.This flange 18 is equipped with notches 19 which thus provide, between the flange 18 and the wall 170, a space adapted to receive the tabs 6, of the outer flange 5 of the cover 2. A connection system is thus produced. bayonet type, between the enclosure 17 and the container 1. This first connection allows to secure the speakers independently of a second connection between the door 16 and the cover 2.

Pour réaliser cette seconde connexion, la porte 16 de l'enceinte 17 est également équipée d'une bride 20 dite centrale, de plus petit diamètre que la bride 18 et concentrique à cette dernière lorsque la porte 16 est fermée. Cette bride 20 est pourvue de pattes 21 régulièrement espacées et s'étendant radialement en direction de l'extérieur de la porte 16, parallèlement au plan principal P'. Ces pattes 21 sont séparées par des décrochements 21'. Le bride 20 a des dimensions adaptées pour venir s'engager dans l'espace disponible entre le fond 11 du couvercle 2 et la bride 9, au niveau des encoches 10 de la bride 9. En d'autres termes, la porte 16 a des dimensions et une configuration correspondant à celles du couvercle 2. En particulier, la partie intérieure 7 du couvercle 2 est équipée de la bride 9 qui coopère avec la bride 20 de la porte 16, de manière à assurer la solidarisation de la porte 16 et du couvercle 2.To make this second connection, the door 16 of the enclosure 17 is also equipped with a so-called central flange 20, of smaller diameter than the flange 18 and concentric with the latter when the door 16 is closed. This flange 20 is provided with lugs 21 regularly spaced and extending radially towards the outside of the door 16, parallel to the main plane P '. These tabs 21 are separated by recesses 21 '. The flange 20 has dimensions adapted to engage in the space available between the bottom 11 of the cover 2 and the flange 9, at the notches 10 of the flange 9. In other words, the door 16 has dimensions and a configuration corresponding to those of the lid 2. In particular, the inner portion 7 of the lid 2 is equipped with the flange 9 which cooperates with the flange 20 of the door 16, so as to ensure the fastening of the door 16 and the cover 2.

On réalise ainsi un second système de connexion, également de type baïonnette, pour la connexion des portes 2, 16 entre elles, indépendamment de la connexion du container 1 et de l'enceinte 17.A second connection system, also of the bayonet type, is thus produced for connecting the doors 2, 16 to one another, independently of the connection of the container 1 and the enclosure 17.

Pour réaliser cette connexion, il convient que la porte 16 et le couvercle 2 soient en appui l'un contre l'autre, avec un matelas d'air entre les deux d'épaisseur la plus faible possible. A cet effet, les empreintes 12, 15 de formes complémentaires, coopèrent. L'empreinte 15, s'étend à l'extérieur de la porte 16 au-delà du plan P', comme illustré à la figure 3. En d'autres termes, la hauteur H15 de l'empreinte 15, sur laquelle celle-ci fait saillie par rapport au plan P' de la porte 16, est telle qu'il n'est pas possible d'avoir un contact, sur toute la surface, entre la porte 16 et le couvercle d'un container, dans le cas où ce couvercle n'est pas creux et pourvu d'une empreinte 12 de forme complémentaire à celle de l'empreinte 15.To achieve this connection, it is appropriate that the door 16 and the lid 2 are pressed against each other, with an air mattress between the two as thin as possible. For this purpose, the impressions 12, 15 of complementary shapes cooperate. The impression 15 extends outside the door 16 beyond the plane P ', as illustrated in FIG. figure 3 . In other words, the height H 15 of the recess 15, on which it protrudes with respect to the plane P 'of the door 16, is such that it is not possible to have a contact, over the entire surface, between the door 16 and the lid of a container, in the case where the lid is not hollow and provided with an imprint 12 of shape complementary to that of the imprint 15.

Lorsque la porte 16 et le couvercle 12 sont solidarisés, il faut les manoeuvrer afin d'accéder à l'intérieur du container 1 et/ou de l'enceinte 17. Pour cela, la porte 16 de l'enceinte 17 est montée sur une charnière 22 positionnée sur la face interne de la paroi 170 de l'enceinte 17. Un bouton de manoeuvre 23 permet d'ouvrir la porte 16, celle-ci s'ouvrant par conséquent en direction de l'intérieur de l'enceinte 17.When the door 16 and the cover 12 are secured, they must be maneuvered to access the interior of the container 1 and / or the enclosure 17. For this, the door 16 of the enclosure 17 is mounted on a hinge 22 positioned on the inner face of the wall 170 of the enclosure 17. A button operation 23 opens the door 16, which consequently opens towards the interior of the enclosure 17.

La face intérieure 24 de cette porte 16 reçoit un organe de sécurité 25. Cet organe de sécurité ou verrou 25 permet de maintenir la porte 16 en position verrouillée, par exemple lorsque l'enceinte 17 n'est pas connectée à une autre enceinte prédéfinie, telle que le container 1. Cet organe de sécurité 25 permet également d'éviter une séparation accidentelle entre les enceintes 17 et 1 connectées, lorsque la porte 16 et le couvercle 2 sont en positions ouvertes.The inner face 24 of this door 16 receives a safety member 25. This safety member or lock 25 makes it possible to keep the door 16 in the locked position, for example when the enclosure 17 is not connected to another predefined enclosure, such as the container 1. This safety member 25 also prevents accidental separation between the speakers 17 and 1 connected, when the door 16 and the lid 2 are in open positions.

Pour cela, cet organe de sécurité 25 est fixé à la paroi 170 de l'enceinte 17. Il comprend un bras de manoeuvre 26 permettant sa mise en rotation autour d'un axe géométrique B-B' perpendiculaire à la face intérieure 24 de la porte 16 et au plan P'.For this, this safety member 25 is fixed to the wall 170 of the enclosure 17. It comprises an operating arm 26 for its rotation around a geometric axis BB 'perpendicular to the inner face 24 of the door 16 and on the plane P '.

Dans la position illustrée aux figures 3 et 4, ce verrou 25, empêche toute ouverture de la porte. Un doigt aplati 27, s'étendant à partir du corps principal 28 du verrou 25, est en appui sur la face intérieure 24 de la porte 16. Dans cette position, une traction sur le bouton 23 dans le sens de la flèche F1 à la figure 6, ne permet pas d'ouvrir la porte 16, le doigt 27 empêchant ce mouvement.In the position illustrated in figures 3 and 4 this latch 25 prevents any opening of the door. A flattened finger 27, extending from the main body 28 of the lock 25, bears on the inner face 24 of the door 16. In this position, a pull on the button 23 in the direction of the arrow F1 to the figure 6 , does not open the door 16, the finger 27 preventing this movement.

Le corps principal 28 du verrou 25 est également pourvu d'une gorge hélicoïdale 29 s'étendant en direction de l'intérieur du corps 28, à partir de la face inférieure du corps 28 qui est en appui contre la paroi 170 de l'enceinte 17. La gorge 29 est visible aux figures 6 et 8.The main body 28 of the lock 25 is also provided with a helical groove 29 extending towards the inside of the body 28, from the lower face of the body 28 which bears against the wall 170 of the enclosure 17. The throat 29 is visible to figures 6 and 8 .

Dans la position illustrée aux figures 3 et 4, la partie 290 la plus profonde de la gorge 29 est située au-dessus d'une tige 30. Cette tige 30 est orientée parallèlement à l'axe B-B'. La tige 30 est disposée dans un puits 31 ménagé dans la paroi 170 de l'enceinte 17. La tige 30 comprend une collerette 32 s'étendant radialement en direction des parois du puits 31. Entre le fond du puits 31 et la collerette 32, la tige 30 est équipée d'un organe de rappel 33, en l'espèce un ressort à boudins. La tige 30 est mobile en translation dans le puits 31. Son déplacement, dans un sens, à savoir en direction du corps 28, s'effectue sous l'action du ressort 33 et son déplacement, en sens inverse, s'effectue à l'encontre de la force de rappel du ressort 33, par appui de la rampe 29 sur la tige 30.In the position illustrated in figures 3 and 4 , the deepest portion 290 of the groove 29 is located above a rod 30. This rod 30 is oriented parallel to the axis B-B '. The rod 30 is disposed in a well 31 formed in the wall 170 of the enclosure 17. The rod 30 comprises a collar 32 extending radially towards the walls of the well 31. Between the bottom of the well 31 and the collar 32, the rod 30 is equipped with a return member 33, in this case a coil spring. The rod 30 is movable in translation in the well 31. Its movement, in one direction, namely towards the body 28, is effected under the action of the spring 33 and its displacement, in the opposite direction, is carried out against the return force of the spring 33, by pressing the ramp 29 on the rod 30.

Le fond du puits 31 est situé au dessus de la bride 18 entourant la porte 16, plus précisément au dessus de l'espace recevant les pattes 6 de la bride 5 du couvercle 2. Le fond du puits 31 est percé. Ainsi, le puits 31 débouche sous la bride 18. L'ouverture ménagée dans le fond du puits est adaptée pour permettre le seul passage de la tige 30. Dans la configuration illustrée à la figure 4, la gorge 29 est en appui, au niveau de sa zone 290 de grande profondeur, sur la tige 30 mais sans déplacer celle-ci en direction du fond du puits 31. En d'autres termes, l'extrémité inférieure de la tige 30 ne débouche pas dans l'espace situé sous la bride 18.The bottom of the well 31 is located above the flange 18 surrounding the door 16, more precisely above the space receiving the tabs 6 of the flange 5 of the cover 2. The bottom of the well 31 is pierced. Thus, the well 31 opens out under the flange 18. The opening in the bottom of the well is adapted to allow the single passage of the rod 30. In the configuration illustrated in FIG. figure 4 , the groove 29 is supported, at its area 290 of great depth, on the rod 30 but without moving it towards the bottom of the well 31. In other words, the lower end of the rod 30 does not open into the space under the flange 18.

En revanche, dans la configuration illustrée aux figures 5 et 6, le corps 28 du verrou 25 a pivoté et le doigt 27 n'est plus en appui sur la face intérieure 24 de la porte 16. Le doigt 27 est orienté à l'opposé de la porte 16, en appui sur la paroi 170 de l'enceinte 17. Dans cette position, il n'interdit plus une manoeuvre d'ouverture de la porte 16. La partie 291 la moins profonde de la rampe 29 est alors en appui sur l'extrémité de la tige 30. Ceci a pour effet de déplacer la tige 30 en direction du fond du puits 31. Dans ce cas, l'extrémité inférieure 300 de la tige 30 traverse le fond du puits 31 et obstrue partiellement l'espace sous la bride 18. Lorsqu'une patte 6 de la bride extérieure 5 du container 1 est insérée dans cet espace, la tige 30 forme une butée à un déplacement de cette patte 6 dans cet espace. En d'autres termes, lorsque le container 1 est connecté à l'enceinte 17 par coopération des pattes 6 avec la bride 18, un mouvement de rotation visant à désolidariser les brides 18 et 5 est empêché par la tige 30. Ainsi, on évite, lorsque la porte 16 de l'enceinte 17 est ouverte, une désolidarisation, accidentelle ou non, du container 1 et de l'enceinte 17.On the other hand, in the configuration illustrated figures 5 and 6 , the body 28 of the lock 25 has pivoted and the finger 27 is no longer supported on the inner face 24 of the door 16. The finger 27 is oriented opposite the door 16, resting on the wall 170 of the enclosure 17. In this position, it no longer prohibits a maneuver opening the door 16. The shallower part 291 of the ramp 29 is then supported on the end of the rod 30. This has for effect of moving the rod 30 towards the bottom of the well 31. In this case, the lower end 300 of the rod 30 passes through the bottom of the well 31 and partially obstructs the space under the flange 18. When a leg 6 of the outer flange 5 of the container 1 is inserted in this space, the rod 30 forms a stop to a displacement of this lug 6 in this space. In other words, when the container 1 is connected to the enclosure 17 by cooperation of the tabs 6 with the flange 18, a rotational movement to disengage the flanges 18 and 5 is prevented by the rod 30. Thus, it avoids when the door 16 of the enclosure 17 is open, a separation, accidental or not, of the container 1 and the enclosure 17.

Le verrou 25 est donc adapté pour passer d'une première position où il interdit l'ouverture de la porte 16 tout en permettant la déconnexion entre l'enceinte 17 et le container 1, à une seconde position où il permet l'ouverture de la porte 16 tout en interdisant la séparation des enceintes 1, 17 connectées. Ces postions sont obtenues par le déplacement en rotation autour de l'axe BB' d'un logement de réception de profondeur variable, en l'espèce la gorge 29, ce logement étant propre à recevoir un organe de blocage mobile en translation, en l'espèce la tige 30. Il est possible, par sécurité, de visualiser les positions du verrou 25 correspondant à l'ouverture et au blocage de la porte 16, par exemple par un marquage visuel sur le doigt 27 et la face 24 de la porte 16.The lock 25 is adapted to move from a first position where it prohibits the opening of the door 16 while allowing the disconnection between the enclosure 17 and the container 1, at a second position where it allows the opening of the door 16 while prohibiting the separation of connected speakers 1, 17. These positions are obtained by rotating in rotation about the axis BB 'of a receiving housing of variable depth, in this case the groove 29, this housing being adapted to receive a locking member movable in translation, in this case the rod 30. It is possible, for safety, to view the positions of the lock 25 corresponding to the opening and locking of the door 16, for example by a visual marking on the finger 27 and the face 24 of the door 16.

L'empreinte 15 de la porte 16 de l'enceinte 17 est montée libre en rotation autour d'un axe matérialisé par un arbre central 34 inséré dans un logement 35 ménagé dans l'épaisseur de la porte 16 comme illustré aux figures 8 à 10. Cet arbre 34 est orienté selon une direction perpendiculaire à la face intérieure 24 de la porte 16. L'arbre 34 est ainsi parallèle à l'axe B-B' du verrou 25, lorsque la porte 16 est fermée. Dans ce cas, l'axe longitudinal de l'arbre 34 est confondu avec l'axe longitudinal A-A' du col 3, lorsque le container 1 est connecté à l'enceinte 17.The impression 15 of the door 16 of the enclosure 17 is mounted free to rotate about an axis represented by a central shaft 34 inserted in a housing 35 formed in the thickness of the door 16 as illustrated in FIGS. Figures 8 to 10 . This shaft 34 is oriented in a direction perpendicular to the inner face 24 of the door 16. The shaft 34 is thus parallel to the axis BB 'of the latch 25, when the door 16 is closed. In this case, the longitudinal axis of the shaft 34 coincides with the longitudinal axis AA 'of the neck 3, when the container 1 is connected to the enclosure 17.

Des ailes latérales 36, visibles à la figure 10, situées à la base de l'empreinte 15 sont en appui sur la face interne de la paroi du logement 35, de manière à éviter une sortie de l'empreinte 15 hors de son logement 35. Une pièce 37, en forme de disque plat, est positionnée entre le fond du logement 35 et les ailes 36. Cette pièce 37 est partiellement insérée dans la zone centrale 350 de la porte 16 recevant l'arbre 34. Cette pièce 37 est solidaire des ailes 36 afin de les maintenir en appui contre la paroi du logement 35. L'empreinte 15 est donc immobilisée en translation dans son logement 35, tout en étant guidée en rotation.Lateral wings 36, visible at the figure 10 , located at the base of the recess 15 bear on the inner face of the wall of the housing 35, so as to avoid an output of the cavity 15 out of its housing 35. A piece 37, flat disk-shaped is positioned between the bottom of the housing 35 and the wings 36. This piece 37 is partially inserted into the central zone 350 of the door 16 receiving the shaft 34. This piece 37 is integral with the wings 36 to hold them in abutment against the wall of the housing 35. The impression 15 is immobilized in translation in its housing 35, while being guided in rotation.

Cette pièce 37 est une partie constitutive de la porte 16 et elle est pourvue d'au moins une fente 38 en arc de cercle. En fait, comme illustré à la figure 7, la pièce annulaire est équipée de deux fentes 38 en arc de cercle donc les concavités sont orientées selon des directions opposées. Avantageusement, ces fentes 38 sont disposées à 120° l'une par rapport à l'autre. En variante, le nombre des fentes 38 est différent, par exemple il est de trois. De même, celles-ci peuvent être disposées différemment, par exemple à 180°.This piece 37 is a constituent part of the door 16 and is provided with at least one slot 38 in an arc. In fact, as illustrated in figure 7 the annular piece is equipped with two slots 38 in an arc so the concavities are oriented in opposite directions. Advantageously, these slots 38 are arranged at 120 ° relative to each other. Alternatively, the number of slots 38 is different, for example it is three. Similarly, they can be arranged differently, for example at 180 °.

Deux barres de blocage 39, dont les dimensions sont adaptées, sont insérées, par une extrémité 390, dans deux supports 40, la base 400 de chaque support 40 étant logée dans une fente 38. Chaque base 400 est solidaire d'une aile 36 de l'empreinte 15. Ainsi, le déplacement de chaque support 40 dans une fente 38 est sous l'action directe du mouvement de rotation de l'empreinte 15 par l'intermédiaire du mouvement solidaire des ailes 36, de la base 400 et de la pièce 37. Lors du déplacement de chaque support 40 dans la fente 38, compte tenu de la géométrie de ces fentes, on provoque un déplacement en translation des barres de blocage 39. Les logements 41 sont également disposés à 120° l'un par rapport à l'autre. Ce déplacement est réalisé dans deux logements 41, de section adaptée pour permettre le déplacement en translation des barres de blocage 39. Les logements 41 sont également disposés à 120° l'un par rapport à l'autre. Ce déplacement est guidé par des reliefs 391 situés à proximité d'une extrémité libre 392 de chaque barre 39. Ces reliefs 391 coulissent dans une partie du logement 41. Ces logements 41 s'étendent sur une longueur supérieure à la longueur des barres 39 et débouchent sur le bord périphérique de la porte 16.Two locking bars 39, the dimensions of which are adapted, are inserted, at one end 390, into two supports 40, the base 400 of each support 40 being housed in a slot 38. Each base 400 is integral with a wing 36 of the impression 15. Thus, the displacement of each support 40 in a slot 38 is under the direct action of the rotational movement of the cavity 15 via the integral movement of the wings 36, the base 400 and the part 37. When moving each support 40 in the slot 38 , given the geometry of these slots, it causes a translational movement of the locking bars 39. The housings 41 are also arranged at 120 ° relative to each other. This movement is carried out in two housings 41, of section adapted to allow the translational movement of the locking bars 39. The housings 41 are also arranged at 120 ° relative to each other. This displacement is guided by reliefs 391 located near a free end 392 of each bar 39. These reliefs 391 slide in a portion of the housing 41. These housings 41 extend over a length greater than the length of the bars 39 and open on the peripheral edge of the door 16.

Comme illustré à la figure 9, lorsque la porte 16 est en position fermée, un logement 42, de même dimension qu'un logement 41 et débouchant également sur la paroi périphérique de l'ouverture dans laquelle se trouve la porte 16, est disposé en regard de chaque logement 41. En d'autres termes, dans cette configuration, deux logements 42 ménagés dans la paroi 170 de l'enceinte 17 prolongent les logements 41 ménagés dans la porte 16. Ces logements 41 et 42 sont respectivement disposés parallèlement à la face intérieure 24 de la porte 16 et à la paroi 170 de l'enceinte 17, lorsque la porte 16 est fermée. Dans l'exemple illustré à la figure 7, la disposition des fentes 38 permet de déplacer selon des directions différentes les barres de blocage 39, lors d'une même rotation de l'empreinte 15. Si ce déplacement a lieu selon des directions différentes, le sens du déplacement des barres 39 est le même. En d'autres termes, la rotation de l'empreinte 15 permet de repousser les barres 39 depuis les logements 41 en direction des logements 42, les deux barres 39 étant déplacées simultanément en direction des logements 42.As illustrated in figure 9 when the door 16 is in the closed position, a housing 42 of the same size as a housing 41 and also opening on the peripheral wall of the opening in which the door 16 is located, is arranged opposite each housing 41. In other words, in this configuration, two housings 42 formed in the wall 170 of the enclosure 17 extend the housings 41 formed in the door 16. These housings 41 and 42 are respectively arranged parallel to the inner face 24 of the door 16 and the wall 170 of the enclosure 17, when the door 16 is closed. In the example shown in figure 7 , the disposition of the slots 38 makes it possible to move the locking bars 39 in different directions during the same rotation of the impression 15. If this displacement takes place in different directions, the direction of movement of the bars 39 is the even. In other words, the rotation of the recess 15 makes it possible to push the bars 39 from the recesses 41 towards the recesses 42, the two bars 39 being moved simultaneously toward the recesses 42.

Les longueurs de ces barres de blocage 39 sont telles qu'elles sortent des logements 41 lorsqu'elles sont en position d'avance maximum, c'est-à-dire lorsque les supports 40 sont situés à l'extrémité des fentes 38 qui sont les plus éloignées de l'arbre central 34. La partie terminale 392 de chaque barre 39 s'étendant à l'extérieur du logement 41 est, dans ce cas, logée dans le logement 42 correspondant lorsque la porte 16 est fermée. En d'autres termes, les barres 39 atteignent, par rotation de l'empreinte 15, une position de verrouillage de la porte fermée. Ce verrouillage permet de maintenir la porte 16 fermée, que l'organe de sécurité 25 soit ou non en position fermée.The lengths of these locking bars 39 are such that they come out of the housings 41 when they are in the maximum advance position, that is to say when the supports 40 are located at the end of the slots 38 which are the farthest from the central shaft 34. The end portion 392 of each bar 39 extending outside the housing 41 is, in this case, housed in the housing 42 corresponding when the door 16 is closed. In other words, the bars 39 reach, by rotation of the cavity 15, a locking position of the closed door. This locking makes it possible to keep the door 16 closed, whether the safety member 25 is in the closed position or not.

La position de l'empreinte 15, qui est accessible et manoeuvrable seulement depuis l'extérieur de l'enceinte 17, permet de réaliser un verrouillage optimal de la porte 16. Celle-ci ne peut alors être déverrouillée qu'à partir de l'extérieur de l'enceinte 17 par rotation de l'empreinte 15, cette rotation n'étant possible que si une empreinte 12 complémentaire est connectée à l'empreinte 15.The position of the footprint 15, which is accessible and operable only from outside the enclosure 17, allows for optimal locking of the door 16. It can then be unlocked only from the outside of the enclosure 17 by rotation of the cavity 15, this rotation being possible only if a complementary cavity 12 is connected to the cavity 15.

Ainsi, les organes 15, 12 permettent, d'une part, d'assurer une liaison qu'entre une enceinte 17 et un container 1 prédéterminés et, d'autre part, de n'autoriser les manoeuvres de la porte 16 et du couvercle 2 qu'entre des portes 16, 2 de formes complémentaires.Thus, the members 15, 12 make it possible, on the one hand, to ensure a connection between a predetermined enclosure 17 and a container 1 and, on the other hand, to prevent the operations of the door 16 and the cover 2 between doors 16, 2 of complementary shapes.

Par ailleurs, la configuration des empreintes 12, 15 permet de repérer la position dans laquelle les deux enceintes 1, 17 doivent être présentées pour être solidarisées. En d'autres termes, les organes 12, 15 constituent également un détrompeur pour la connexion des deux enceintes 1, 17.Moreover, the configuration of the imprints 12, 15 makes it possible to identify the position in which the two enclosures 1, 17 must be presented to be secured. In other words, the members 12, 15 also constitute a key for the connection of the two enclosures 1, 17.

En se référant aux figures 3 à 6, on décrit maintenant la solidarisation des enceintes 1, 17, des portes 2, 16 puis leur manoeuvre mutuelle afin de mettre en relation les volumes internes du container 1 et de l'enceinte 17.Referring to Figures 3 to 6 , the interconnection of the enclosures 1, 17, doors 2, 16 and their mutual operation is described in order to relate the internal volumes of the container 1 and the enclosure 17.

A la figure 3, on présente l'une en face de l'autre, l'enceinte 17 et le container 1 à mettre en relation. Lors de cette présentation, on positionne l'empreinte 12 du couvercle 2 du container 1 en face de l'empreinte 15 de la porte 16 de l'enceinte 17 dans une position où les reliefs complémentaires peuvent venir en prise mutuelle. Le motif 151 de l'empreinte 15 est inséré dans le motif 121 de l'empreinte 12, le bord 152 coopérant avec la nervure 122. En variante, les empreintes 12, 15 ne comportent qu'un motif 121, 122, 151, 152 coopérant avec un motif complémentaire 151, 152, 121, 122. Ainsi, l'empreinte 15, dite mâle, de la porte 16 de l'enceinte 17 est insérée dans l'empreinte 12, dite femelle, du couvercle 2 du container 1. En variante, les positions des empreintes mâle et femelle peuvent être inversées, l'empreinte 15 mâle étant, non pas sur la porte 16 de l'enceinte 17, mais sur le couvercle 2 du container 1. On qualifie également de positif l'empreinte 15 mâle, c'est-à-dire l'empreinte en relief et de négatif l'empreinte 12 femelle c'est-à-dire l'empreinte en creux, avec le code alphanumérique et/ou la forme en position miroir.To the figure 3 , one faces opposite to the other, the enclosure 17 and the container 1 to put in relation. During this presentation, the cavity 12 of the lid 2 of the container 1 is positioned facing the cavity 15 of the door 16 of the enclosure 17 in a position where the complementary reliefs can come into mutual engagement. The pattern 151 of the imprint 15 is inserted in the pattern 121 of the imprint 12, the edge 152 cooperating with the rib 122. In a variant, the imprints 12, 15 comprise only a pattern 121, 122, 151, 152 cooperating with a complementary pattern 151, 152, 121, 122. Thus, the so-called male footprint 15 of the door 16 of the enclosure 17 is inserted into the so-called female footprint 12 of the lid 2 of the container 1. Alternatively, the positions of male and female fingerprints can be reversed, the male fingerprint being, not on the door 16 of the chamber 17, but on the lid 2 of the container 1. The male fingerprint is also positive, it is that is to say, the embossed imprint and negative the female imprint 12, that is to say the intaglio imprint, with the alphanumeric code and / or the shape in the mirror position.

On effectue ensuite une première rotation du container 1 autour de l'axe A-A', l'enceinte 17 restant immobile. Dans l'exemple, cette rotation est réalisée dans le sens inverse des aiguilles d'une montre. En variante, elle peut être réalisée dans le sens des aiguilles d'une montre. Cette rotation permet d'engager les pattes 6 de la bride extérieure 5 du couvercle 2 du container 1 sous la bride fixe 18 de la paroi 170 de l'enceinte 17 entourant la porte 16. Une fois la rotation de ce premier dispositif de connexion de type à baïonnette réalisée, les lèvres 4 du col 3 du container 1 sont en appui contre la paroi 170, sous la bride 18. En d'autres termes, avec cette première rotation, on a solidarisé ensemble les deux enceintes 1, 17, pour atteindre la configuration illustrée à la figure 4.Then a first rotation of the container 1 around the axis A-A ', the enclosure 17 remaining stationary. In the example, this rotation is performed in the opposite direction of the clockwise. Alternatively, it can be performed in the direction of clockwise. This rotation makes it possible to engage the lugs 6 of the outer flange 5 of the lid 2 of the container 1 under the fixed flange 18 of the wall 170 of the enclosure 17 surrounding the door 16. Once the rotation of this first connection device bayonet type performed, the lips 4 of the neck 3 of the container 1 are in abutment against the wall 170, under the flange 18. In other words, with this first rotation, the two enclosures 1, 17 have been secured together for achieve the configuration illustrated in the figure 4 .

Ce premier mouvement de rotation n'est néanmoins pas suffisant pour entraîner la connexion de la porte 16 et du couvercle 2, bien que l'empreinte 15 ait amorcé une rotation, entraînée par l'empreinte fixe 12 du couvercle 2. La porte 16 de l'enceinte 17 est toujours bloquée en position fermée par les barres 39 insérées dans les logements 42 ménagés dans la paroi 170 de l'enceinte 17. Ce blocage de la porte 16 est également sécurisé par le verrou 25, qui est dans une position de verrouillage où le doigt 27 est en appui sur la porte 16. Dans cette configuration, la fermeture de la porte 16 est sécurisée.This first rotational movement is nevertheless not sufficient to cause the connection of the door 16 and the cover 2 to be connected, although the impression 15 has initiated a rotation driven by the fixed impression 12 of the cover 2. The door 16 of the enclosure 17 is always locked in the closed position by the bars 39 inserted in the housings 42 formed in the wall 170 of the enclosure 17. This blocking of the door 16 is also secured by the lock 25, which is in a position of locking where the finger 27 is supported on the door 16. In this configuration, the closing of the door 16 is secured.

Comme illustré à la figure 5, le mouvement de rotation, dans le même sens, du couvercle 2 se poursuit, ce qui entraîne les pattes 21 de la bride intérieure 20 de la porte 16 dans une position où elles sont logées sous la bride 9 du couvercle 2.As illustrated in figure 5 , the rotational movement in the same direction of the lid 2 continues, which causes the tabs 21 of the inner flange 20 of the door 16 in a position where they are housed under the flange 9 of the lid 2.

Lorsque cette rotation est achevée, typiquement après une rotation du couvercle 2 comprise entre 30° et 60°, la porte 16 et le couvercle 2 sont parfaitement connectés.When this rotation is completed, typically after a rotation of the lid 2 between 30 ° and 60 °, the door 16 and the lid 2 are perfectly connected.

Lors de ce second mouvement de rotation, on déplace complètement les barres de blocage 39 puisque chaque support 40 est, en fin de déplacement dans la fente 38, au niveau de l'extrémité située prés de l'arbre central 34. Ceci permet de déplacer les barres de blocage 39 vers le fond de leurs logements 41, le plus près de l'axe A-A'. Les barres 39 ne dépassent alors plus de la périphérie de la porte 16. On autorise ainsi la manoeuvre de la porte 16 de l'enceinte, celle-ci n'étant plus bloquée en position fermée par les barres 39 qui ne sont plus insérées dans les logements 42. Seul le verrou 25 assure encore le verrouillage en position fermée de la porte 16.During this second rotational movement, the locking bars 39 are completely displaced since each support 40 is, at the end of its displacement in the slot 38, at the end located near the central shaft 34. This makes it possible to move the locking bars 39 towards the bottom of their housings 41, closest to the axis A-A '. The bars 39 then no longer protrude beyond the periphery of the door 16. This authorizes the operation of the door 16 of the enclosure, the latter being no longer locked in the closed position by the bars 39 which are no longer inserted in the housings 42. Only the lock 25 still ensures the locking in the closed position of the door 16.

La poursuite du mouvement de rotation du couvercle 2 du container ne permet plus d'entraîner en rotation l'empreinte 15 puisque les supports 40, solidaires de l'empreinte 15, sont en butée contre une extrémité des fentes 38. Le container 1 peut être entraîné en rotation par rapport au couvercle 2, sur une course faible, correspondant sensiblement à la longueur des branches 140 des encoches 14. En d'autres termes, en fin de mouvement, le couvercle 2 et la porte 16 sont immobiles en rotation, par rapport au container 1, alors que celui-ci peut pivoter. Ainsi, on désolidarise le couvercle 2 du col 3 du container. Le couvercle 2 peut être alors aisément retiré, par traction selon la flèche F1 à la figure 6, lors de l'ouverture de la porte 16 à laquelle il est relié. A la fin de cette rotation, la couvercle 2 et la porte 16 sont en position déverrouillée, c'est-à-dire respectivement désolidarisées du col 3 du container 1 et de la paroi 170 dans l'enceinte 17.Continuing the rotational movement of the lid 2 of the container no longer makes it possible to rotate the impression 15 since the supports 40, integral with the impression 15, abut one end of the slots 38. The container 1 may be rotated relative to the cover 2, on a low stroke, corresponding substantially to the length of the branches 140 of the notches 14. In other words, at the end of the movement, the cover 2 and the door 16 are immobile in rotation, by compared to the container 1, while it can rotate. Thus, the lid 2 of the neck 3 of the container is detached. The lid 2 can then be easily removed by pulling along the arrow F1 to the figure 6 when opening the door 16 to which it is connected. At the end of this rotation, the cover 2 and the door 16 are in the unlocked position, that is to say respectively disengaged from the neck 3 of the container 1 and the wall 170 in the enclosure 17.

La manoeuvre simultanée du couvercle 2 et de la porte 16 est possible grâce au bouton de manoeuvre 23 situé sur la face intérieure 24 de la porte 16. Pour réaliser cette manoeuvre, il est nécessaire de mettre le verrou 25 en position déverrouillée. Pour cela, on effectue une rotation de 180° du verrou 25 autour de l'axe B-B'. Cette rotation permet de dégager le doigt 27 du verrou 25 qui n'est alors plus en appui sur la porte 16. Lors de ce mouvement de rotation, la rampe hélicoïdale 29 a également pivoté et sa zone 291 de moindre profondeur se trouve en appui contre l'extrémité supérieure 301 de la tige 30. Cette dernière est donc déplacée en direction du fond du puits 31. L'extrémité 300 de la tige 30 est ainsi positionnée entre les pattes 6 de la bride 5. En d'autres termes, la tige 30 bloque en rotation la bride 5. De cette manière, il n'est pas possible d'effectuer une manoeuvre de rotation du container 1 en sens inverse, pour le désolidariser de l'enceinte 17. On peut donc ouvrir les portes 2, 16 comme illustré à la figure 6, pour mettre en relation les contenus des deux enceintes 1, 17.The simultaneous operation of the cover 2 and the door 16 is possible thanks to the operating knob 23 located on the inner face 24 of the door 16. To perform this operation, it is necessary to put the lock 25 in the unlocked position. For this purpose, the latch 25 is rotated 180 ° about the axis B-B '. This rotation makes it possible to disengage the finger 27 from the latch 25 which is then no longer supported on the door 16. During this rotational movement, the helical ramp 29 has also rotated and its zone 291 of lesser depth is bearing against the upper end 301 of the rod 30. The latter is moved towards the bottom of the well 31. The end 300 of the rod 30 is thus positioned between the legs 6 of the flange 5. In in other words, the rod 30 blocks the flange 5 in rotation. In this way, it is not possible to carry out a rotation maneuver of the container 1 in the opposite direction, in order to separate it from the enclosure 17. so open the doors 2, 16 as shown in the figure 6 to relate the contents of the two enclosures 1, 17.

Les manoeuvres inverses, c'est-à-dire fermeture de la porte 16, rotation du verrou 25 afin de ramener la tige 30 à sa position initiale, rotation du container 1 dans le sens inverse afin de ramener les barres de blocage 39 au fond des logements 42 dans la paroi 170, verrouillage des ergots 13 du couvercle 2 dans les fentes sur le col 3 du container et rotation finale pour dégager le container 1 de l'enceinte 17, sont à effectuer pour séparer les deux enceintes 1, 17 après avoir fermé la porte 16 et le couvercle 2.Inverse maneuvers, that is to say, closing the door 16, rotation of the lock 25 to bring the rod 30 back to its initial position, rotation of the container 1 in the opposite direction to bring the locking bars 39 to the bottom housings 42 in the wall 170, locking the lugs 13 of the cover 2 in the slots on the neck 3 of the container and final rotation to clear the container 1 of the enclosure 17, are to be performed to separate the two enclosures 1, 17 after have closed the door 16 and the lid 2.

Grâce à l'invention, on a réalisé un dispositif de connexion, étanche, sécurisé, tout en préservant la stérilité de l'intérieur des deux enceintes 1, 17.Thanks to the invention, a connection device has been made, sealed, secure, while preserving the sterility of the interior of the two enclosures 1, 17.

Lorsque l'on souhaite ouvrir la porte 16 de l'enceinte 17 pour effectuer des opérations de maintenance et/ou de stérilisation sur la face extérieure de cette porte 16, ce qui permet également de stériliser l'empreinte 15 et son logement 35, on peut utiliser un dispositif reproduisant la partie du col 3 du container 1 équipé du couvercle 2. En d'autres termes, la partie de volume de réception du container 1 s'étendant au-delà du col n'existe pas dans un tel dispositif, elle est fermée et remplacée, par exemple, par une poignée de manoeuvre.When it is desired to open the door 16 of the enclosure 17 to carry out maintenance and / or sterilization operations on the outer face of this door 16, which also makes it possible to sterilize the cavity 15 and its housing 35, can use a device reproducing the portion of the neck 3 of the container 1 equipped with the lid 2. In other words, the receiving volume portion of the container 1 extending beyond the neck does not exist in such a device, it is closed and replaced, for example, by a maneuvering handle.

Pour la manoeuvre du couvercle 2 sans avoir à le connecter à une porte 16, il convient d'avoir également un outil pourvu d'une empreinte de forme complémentaire à celle de l'empreinte 12.To maneuver the lid 2 without having to connect it to a door 16, it is also necessary to have a tool provided with an impression of a shape complementary to that of the cavity 12.
