Description

Obturateur avec charnière élastique Shutter with elastic hinge
L'invention concerne une structure articulée pour relier un couvercie à un support, qui peut être installée, sur un réservoir, particulièrement en matière plastique, ou qui peut être formée d'une seule pièce avec une section d'ouverture du réservoir.The invention relates to an articulated structure for connecting a cover to a support, which can be installed on a tank, particularly of plastic, or which can be formed in one piece with an opening section of the tank.
Une structure articulée de ce type est par exemple, présentée dans le document US 2004 0016714 A1, pour laquelle le mouvement d'ouverture d'un couvercle est exécuté par une charnière-film. En outre, le mouvement d'ouverture est supporté par une partie de ressort élastomère précontraint située adjacente du côté extérieur de la charnière-film. L'inconvénient de la structure articulée connue réside dans le fait que seules de faibles forces de la partie de ressort élastomère peuvent être mises à disposition pour une ouverture autonome du couvercle. Plus particulièrement, en cas de forte résistance pour un mouvement d'ouverture, cette force d'ouverture de la partie de ressort élastomère ne suffit pas.An articulated structure of this type is for example, presented in US 2004 0016714 A1, for which the opening movement of a cover is performed by a film hinge. In addition, the opening movement is supported by a prestressed elastomeric spring portion located adjacent to the outer side of the film hinge. The disadvantage of the known articulated structure lies in the fact that only small forces of the elastomeric spring part can be made available for an independent opening of the cover. More particularly, in case of high resistance for an opening movement, this opening force of the elastomeric spring portion is not sufficient.
L'invention a pour but d'éliminer les inconvénients de l'état de la technique, plus particulièrement d'améliorer une structure articulée pour relier un couvercle à un support, de sorte que des forces importantes sont mises à disposition pour le mouvement d'ouverture du couvercle.The object of the invention is to eliminate the drawbacks of the state of the art, more particularly to improve an articulated structure for connecting a cover to a support, so that large forces are made available for the movement of opening the lid.
Ce but est résolu par la structure articulée pour relier un couvercle à un support selon l'invention, qui peut être installée sur un réservoir ou peut être formée d'une seule pièce avec une section d'ouverture du réservoir, comprenant un joint articulé pour guider le couvercle entre une position fermée et une position ouverte avec un axe de pivotement situé sur le côté extérieur du couvercle et/ou du support, et une partie de ressort élastomère, qui saisit le côté extérieur du couvercle ainsi que du support et est précontrainte au moins dans la position fermée du couvercle sur tension, qui se distingue en ce qu'un point d'application de force de la partie du ressort élastomère au couvercle et/ou au support au moins dans une position fermée du couvercle est déplacé vers l'extérieur au-delà de l'axe de pivotement du joint articulé. Selon l'invention, la partie de ressort élastomère est précontrainte au moins dans la position fermée du couvercle sur tension, au moins un point d'application de force de la partie de ressort élastomère au couvercle et/ou au support au moins dans la position fermée du couvercle étant déplacé au- delà du joint articulé par rapport au couvercle et/ou au support, en dépassant l'axe de pivotement. La structure articulée selon l ' invention prévoit une séparation structu¬ relle du joint articulé de la partie de ressort élastomère, de sorte qu'il est possible de générer d'importants couples d'entraînement pour ouvrir le couvercle. Grâce au déplacement d'un point d'application de force du couvercle et/ou du support vers l'extérieur, au-delà de l'axe de pivotement, des rapports de levage pour l'ouverture du couvercle entre l'axe de pivotement et la partie de ressort élastomère précontrainte sur tension sont optimisés.This object is solved by the articulated structure for connecting a lid to a support according to the invention, which can be installed on a tank or can be formed in one piece with an opening section of the tank, comprising an articulated joint for guiding the cover between a closed position and an open position with a pivot axis located on the outer side of the cover and / or support, and an elastomeric spring portion, which grips the outer side of the cover and the support and is prestressed at least in the closed position of the lid on tension, which is distinguished in that a point of force application of the portion of the elastomeric spring to the lid and / or the support at least in a closed position of the lid is moved towards the outside the pivot axis of the articulated joint. According to the invention, the elastomer spring portion is preloaded at least in the closed position of the lid on tension, at least one point of force application of the elastomer spring portion to the lid and / or the support at least in the position With the lid closed, the lid is moved beyond the hinged joint with respect to the lid and / or the support, beyond the pivot axis. The articulated structure according to the invention provides a structural separation of the articulated joint of the elastomeric spring portion, so that it is possible to generate large drive torques to open the lid. By moving a point of force application of the cover and / or the support outwards, beyond the pivot axis, lifting ratios for opening the cover between the pivot axis and the tension-preloaded elastomeric spring portion are optimized.
Dans un mode de réalisation préféré de l'invention, la structure articulée peut être formée par une paire de joints articulés avec des axes de pivotement parallèles, de préférence alignés, qui sont associés à une, deux ou plusieurs parties de ressort élastomère précontraintes sous tension au moins dans la position fermée du couvercle. De même, la structure articulée selon l 'invention peut être formée par une paire de parties de ressort élastomère, qui sont associées à un joint articulé plus particulièrement renforcé. Pour obtenir une entrée de force d'ouverture optimale, le joint articulé renforcé peut être disposé au milieu, entre deux parties de ressort élastomère.In a preferred embodiment of the invention, the articulated structure may be formed by a pair of articulated joints with parallel, preferably aligned, pivot axes that are associated with one, two, or more pre-stressed elastomeric spring portions under tension. at least in the closed position of the lid. Similarly, the articulated structure according to the invention can be formed by a pair of elastomer spring parts, which are associated with a particularly reinforced articulated joint. To obtain an optimum opening force input, the reinforced articulated joint can be centrally disposed between two elastomeric spring portions.
Grâce à la mesure selon l'invention de déplacement d'un point d'application de force de la partie de ressort élasto¬ mère au couvercle et/ou au support au-delà de l'axe de pivotement, on obtient que l'ensemble de la partie de ressort .élastomère avec la précontrainte mémorisée, au moins dans la position fermée du couvercle, se situe dans un intervalle plus grand que l'axe de pivotement par rapport au couvercle et/ou au support lequel axe de pivotement est situé de préférence au-delà du côté extérieur du couvercle et/ou du support.Thanks to the measurement according to the invention of displacement of a point of force application of the elasto¬ mother spring portion to the cover and / or the support beyond the pivot axis, we obtain that all of the elastomeric spring portion with the stored preload, at least in the closed position of the cover, is in a greater range than the pivot axis with respect to the cover and / or to the support which pivot axis is preferably located beyond the outer side of the cover and / or support.
Dans un mode de réalisation préféré de l'invention, le déplacement du point d'application de force de la partie de ressort élastomère, plus particulièrement du point d'applica¬ tion de force de la partie en élastomère au niveau du couver¬ cle et du support, est réalisé de sorte qu'au moins une saillie ou une partie en saillie rigide, de préférence deux parties en saillie rigides, sont prévues pour fixer la partie de ressort élastomère au couvercle respectif et/ou au support respectif. Une partie en saillie ou les deux parties en saillie peuvent s'étendre vers l'extérieur plus particu¬ lièrement au-dessus et/ou en dessous de l'axe de pivotement, en le dépassant. De préférence, les deux parties en saillie sont parallèles l'une à l'autre dans la position fermée du couvercle .In a preferred embodiment of the invention, the displacement of the force application point of the elastomer spring portion, more particularly the point of force application of the elastomeric portion at the couver¬ clef and of the support, is made so that at least one protrusion or a rigid projecting part, preferably two rigid protruding parts, are provided for fixing the elastomeric spring part to the respective cover and / or to the respective support. A protruding part or both projecting parts may extend outwardly particu¬ larly above and / or below the pivot axis, exceeding it. Preferably, the two protruding portions are parallel to each other in the closed position of the lid.
Dans un mode de réalisation préféré de l'invention, la partie en saillie ou les parties en saillie sont fabriquées en une pièce avec l'élément respectif, le couvercle ou le support, plus particulièrement, elles sont moulées à partir d'une pièce en matière plastique. La partie de ressort élastomère est fixée aux extrémités des parties en saillie. De préférence, les parties en saillie s'éloignent du couvercle à distance essentiellement égale, de sorte que la partie de ressort élastomère est verticale par rapport à un plan déterminé par le couvercle dans sa position fermée.In a preferred embodiment of the invention, the protruding part or the protruding parts are manufactured in one piece with the respective element, the cover or the support, more particularly, they are molded from a workpiece. plastic material. The elastomeric spring portion is attached to the ends of the projecting portions. Preferably, the projecting portions move away from the substantially equal distance cover, so that the elastomeric spring portion is vertical with respect to a plane determined by the cover in its closed position.
Dans un mode de réalisation de l'invention, les points d'application de force de la partie de ressort élastomère au couvercle et au support se déplacent tellement loin vers l'extérieur, de sorte que l'ensemble de la partie de ressort élastomère reste entre la position fermée et la position ouverte du couvercle par rapport au dernier toujours au-delà de l'axe de pivotement. De cette façon, on garantit que des rapports de levage optimaux sont mis à disposition pendant tout le mouvement d'ouverture pour générer un couple d'entraî¬ nement suffisant. De préférence, la partie de ressort élastomère réalisée de façon structurelle et séparée du joint articulé est réalisée comme bande d'élastomère, dont les points d'application de force s'étendent linéairement et princi- paiement parallèlement à l'axe de pivotement. Le joint articulé peut être réalisé à cet effet comme charnière avec un pivot ou tourillon et un logement cylindrique. De préférence, le pivot est plus particulièrement réalisé d'une seule pièce avec le couvercle, moyennant quoi le logement cylindrique et le support sont fabriqués en une seule pièce .In one embodiment of the invention, the force application points of the elastomeric spring portion to the cover and the support move so far outwardly, so that the entire elastomeric spring portion remains between the closed position and the open position of the cover with respect to the last always beyond the pivot axis. In this way, it is ensured that optimal lifting ratios are provided throughout the opening movement to generate a sufficient torque entrain¬ ment. Preferably, the elastomer spring portion made structurally and separate from the hinged joint is made as an elastomer strip, whose force application points extend linearly and principally parallel to the pivot axis. The articulated joint can be designed for this purpose as a hinge with a pivot or journal and a cylindrical housing. Preferably, the pivot is more particularly made in one piece with the lid, whereby the cylindrical housing and the support are manufactured in one piece.
Dans un mode de réalisation de l'invention, l'axe de pivotement du joint articulé est non-courbé, mais est plus particulièrement droit. Un aspect de l'invention indépendant, mais pouvant également être combiné avec l'objet de l'inven- tion mentionné plus haut, concerne une structure articulée, pour laquelle le joint articulé est prévu pour libérer le couvercle du support. Un dispositif de libération du pivot à charnière du logement cylindrique est conçu pour permettre une séparation dans chaque position de marche du couvercle par rapport au support, plus particulièrement exclusivement dans une position constructive prédéfinie, plus particulièrement une position fermée du couvercle, dans laquelle les forces de tension importantes de la partie de ressort élastomère dominent, lesquelles forcent le pivot à charnière contre un démontage autonome dans le logement cylindrique. Le dispositif de libération est associé de façon fonctionnelle à la partie de ressort élastomère précontrainte sur tension, de sorte que la précontrainte sur tension mémorisée dans la partie de ressort élastomère est alignée par rapport à la direction de démontage. De préférence, le dispositif de libération est réalisé de sorte que le logement cylindrique de l'articulation à charnière est construit du côté du couvercle de façon découverte. De cette façon, le pivot à charnière peut être enlevé dans une position de marche prédéfinie par le côté ouvert du logement cylindrique en surmontant la tension précontrainte de la partie de ressort: élastomère. Un autre aspect de l'invention indépendant des objets de l'invention mentionnés plus haut mais pouvant être combiné avec eux réside dans le fait que la structure articulée doit être prévue avec un dispositif de limitation de pivotement, lequel limite le mouvement d'ouverture du couvercle. La partie de ressort élastomère sert à réaliser un mouvement d'ouverture autonome, moyennant quoi les forces de précontrainte de la partie de ressort élastomère doivent être surmontées pour fermer le couvercle. Lors de l'ouverture du couvercle, le dispositif de limitation de pivotement garantit l'obtention contrôlée d'une position finale prédéfinie.In one embodiment of the invention, the pivot axis of the articulated joint is not curved, but is more particularly straight. An aspect of the invention which is independent, but which can also be combined with the subject of the invention mentioned above, relates to an articulated structure, for which the articulated joint is provided to release the cover of the support. A hinge pivot release device of the cylindrical housing is adapted to allow separation in each operating position of the lid with respect to the support, more particularly exclusively in a predefined constructive position, more particularly a closed position of the lid, in which the forces Important tensioning of the elastomer spring portion dominates, which forces the hinge pin against self-disassembly in the cylindrical housing. The release device is operatively associated with the tension preloaded elastomeric spring portion such that the voltage prestress stored in the elastomeric spring portion is aligned with respect to the disassembly direction. Preferably, the release device is constructed such that the cylindrical housing of the hinge joint is constructed on the cover side uncovered. In this way, the hinged pivot can be removed in a predefined operating position by the open side of the cylindrical housing by overcoming the prestressing tension of the spring portion: elastomer. Another aspect of the invention that is independent of the objects of the invention mentioned above but which can be combined with them lies in the fact that the articulated structure must be provided with a pivot limitation device, which limits the opening movement of the lid. The elastomeric spring portion serves to provide a self-opening movement, whereby the biasing forces of the elastomeric spring portion must be overcome to close the lid. When opening the lid, the pivot limiting device guarantees the controlled obtaining of a predefined final position.
De préférence, le dispositif de limitation de pivotement est formé par une butée intégrée dans le joint articulé. Cette butée peut être formée par au moins un tenon fixé au support, lequel est pointé vers l'intérieur du logement cylindrique du joint articulé et agit sur le pivot à charnière en limitant la rotation. Le tenon doit ainsi de préférence empêcher un démontage du pivot à charnière du logement cylindrique au moins dans la position ouverte du couvercle. Dans un mode de réalisation, le dispositif de limitation de pivotement est réalisé de sorte qu'un mouvement d'ouverture de pivotement du couvercle est limité à environ 90° à partir de la position fermée du couvercle.Preferably, the pivot limitation device is formed by a stop integrated in the articulated joint. This abutment can be formed by at least one stud fixed to the support, which is pointed towards the inside of the cylindrical housing of the articulated joint and acts on the hinged pivot by limiting the rotation. The pin should preferably prevent disassembly of the hinge pin of the cylindrical housing at least in the open position of the lid. In one embodiment, the pivot limiting device is constructed such that a pivot opening movement of the lid is limited to about 90 ° from the closed position of the lid.
De plus, l'invention concerne un dispositif de fermeture pour un réservoir avec un couvercle et une structure articulée selon 1 ' invention.In addition, the invention relates to a closure device for a tank with a lid and an articulated structure according to the invention.

La figure 1 illustre un dispositif de fermeture 1 pour un réservoir en plastique (non représenté) , qui, comme la plupart des éléments du dispositif de fermeture 1, peut être moulé à partir d'une matière plastique. Le dispositif de fermeture 1 comprend, comme élément principal, un support 3 principalement en forme d'anneau - en forme d'anneau dans le sens entièrement entouré -, un couvercle 5 pouvant basculer ou pivoter par rapport au support 3, un dispositif de verrouillage 7, lequel maintient le couvercle dans la position fermée par rapport au support, et une structure articulée 11 selon l'invention, laquelle met à disposition un raccordement articulé entre le couvercle 5 et le support 3 avec un système d'aide pour entraîner l ' ouverture .Figures 13a-13c illustrate the support-cover structure according to Figure 7 respectively in the main operating positions - closed, open waiting, disassembled. Figure 1 illustrates a closure device 1 for a plastic container (not shown), which, like most elements of the closure device 1, can be molded from a plastic material. The closure device 1 comprises, as a main element, a support 3 mainly in the form of a ring - in the form of a ring in the fully encircled direction -, a cover 5 that can swing or pivot relative to the support 3, a locking device 7, which holds the cover in the closed position relative to the support, and an articulated structure 11 according to the invention, which provides an articulated connection between the cover 5 and the support 3 with a help system for driving the opening .
Le support 3 peut, comme illustré sur la figure 1, être conçu comme élément séparé ou comme élément en une seule pièce d'un réservoir non représenté.The support 3 may, as illustrated in Figure 1, be designed as a separate element or as a single piece of a tank not shown.
Le support 3 comprend, du côté intérieur, une lèvre d'étanchéité 12 en élastomère souple agissant conjointement avec le couvercle 5 dans sa position fermée. Le dispositif de verrouillage 7, qui peut être conçu comme dispositif à encliquetage, et qui agit conjointement de façon verrouillée avec un élément opposé du couvercle 5 dans la position fermée du couvercle, est prévu de façon diamétralement opposée à la structure articulée 11 selon l'invention au niveau du côté extérieur du dispositif de fermeture 1.The support 3 comprises, on the inner side, a sealing lip 12 made of flexible elastomer acting in conjunction with the cover 5 in its closed position. The locking device 7, which may be designed as a snap-in device, and which acts together in a locked manner with an opposite element of the cover 5 in the closed position of the cover, is provided diametrically opposite to the articulated structure 11 according to the invention. invention at the outer side of the closure device 1.
Par la suite, des détails du mode de réalisation selon l'invention d'une structure articulée 11 sont décrits en rapport avec les figures 1 à 6.Subsequently, details of the embodiment according to the invention of an articulated structure 11 are described in connection with Figures 1 to 6.
La structure articulée 11 comprend une articulation à charnière 13 et une bande d' élastomère 15, qui est séparée de façon structurelle de l'articulation à charnière 13.The hinged structure 11 comprises a hinge hinge 13 and an elastomer strip 15, which is structurally separated from the hinge hinge 13.
L'articulation à charnière 13 comprend un pivot à charnière 16, qui est maintenu de façon à pouvoir pivoter dans un logement cylindrique 17. Le logement cylindrique 17 est ouvert vers le haut. Au-dessus du logement cylindrique 17 s'étend une paire de tenons, du bord du support 3, dans la zone du logement cylindrique. Chaque tenon 20 comprend une surface d'arrêt 19.The hinge joint 13 includes a hinged pivot 16, which is pivotally held in a cylindrical housing 17. The cylindrical housing 17 is open upwardly. Above the cylindrical housing 17 extends a pair of tenons, the edge of the support 3, in the cylindrical housing area. Each post 20 comprises a stop surface 19.
Le pivot à charnière 16 est formé essentiellement en demi-cercle en travers dans la zone du logement cylin- drique 17, lorsque le couvercle 5 est monté. L'articulation à charnière 13 définit un axe de pivotement S, autour duquel le couvercle 5 peut être pivoté ou basculé.The hinge pin 16 is formed substantially in a semicircle across the region of the cylindrical housing 17 when the cover 5 is mounted. The hinge 13 defines a pivot axis S, around which the cover 5 can be pivoted or tilted.
La bande d'élastomère 15 est reliée au couvercle 5 et au support 3 par des parties en saillie formées d'une seule pièce avec l'élément respectif ou des sections de décalage 21, 23, lesquelles déplacent vers l'extérieur les points d'application de force 25, 27 de la bande d'élastomère 15 en les écartant du support 3 et du couvercle 5, de sorte que l'ensemble de la bande d'élastomère 15 se trouve de l'autre côté de l'axe de pivotement S par rapport au couvercle 5 et au support 3 , l'intervalle de la bande d'élastomère 15 vers le support 3 ou le couvercle 5 étant plus grand que l'intervalle de l'axe de pivotement S vers le support 3 ou le couvercle 5. Comme illustré sur la figure 5, le décalage des points d'application des forces 25, 27 de la bande d'élastomère 15 en position ouverte (figure 6) aussi bien qu'en position fermée (figure 5) du couvercle 5 met à disposition un grand bras de levier a, au niveau duquel un couple d'entraînement suscité est généré par une force de précontrainte F de la bande d'élastomère 15. Même lors du basculement du couvercle 5, la bande d'élastomère 15 reste toujours de l'autre côté de l'axe de pivotement S par rapport au support 3 , de sorte que des bras de levier agissent au cours des mouvements d'ouverture, lesquels permettent de générer un couple fort pour ouvrir le couvercle 5.The elastomer strip 15 is connected to the cover 5 and to the support 3 by projecting parts formed in one piece with the respective element or offset sections 21, 23, which outwardly move the points of contact. application of force 25, 27 of the elastomer strip 15 away from the support 3 and the cover 5, so that the entire elastomer strip 15 is on the other side of the pivot axis S with respect to the cover 5 and the support 3, the interval of the elastomer strip 15 towards the support 3 or the cover 5 being greater than the interval of the pivot axis S towards the support 3 or the cover 5. As illustrated in FIG. 5, the offset of the application points of the forces 25, 27 of the elastomer strip 15 in the open position (FIG. 6) as well as in the closed position (FIG. available a large lever arm a, at which an induced training torque is generated p by a prestressing force F of the elastomer strip 15. Even when the cover 5 is tilted, the elastomer strip 15 remains always on the other side of the pivot axis S with respect to the support 3, so that that lever arms act during the opening movements, which can generate a strong torque to open the lid 5.
Dans une position d'ouverture du couvercle 5 basculée de 90° par rapport au support 3, un côté plat du pivot à charnière 16 bat contre la surface d'arrêt 19 du tenon 20, par lequel un autre basculement du couvercle 5 de la position verticale représentée sur la figure 6 est empêché. Grâce à la force de précontrainte F agissant toujours entre les parties en saillie 21, 23, le couvercle 5 est contraint et maintenu dans la position d'ouverture représentée sur la figure 6.In an open position of the cover 5 tilted 90 ° relative to the support 3, a flat side of the hinge pin 16 beats against the stop surface 19 of the tenon 20, whereby another tilting of the cover 5 of the position vertical shown in Figure 6 is prevented. Thanks to the prestressing force F always acting between the parts protruding 21, 23, the cover 5 is constrained and held in the open position shown in FIG. 6.
Pour maintenir un accès libre par le couvercle 5 à une section d'ouverture 31 du support 3, le raccordement du couvercle 5 avec le support 3 peut être résolu par l'arti¬ culation à charnière 13, alors que le pivot à charnière 16 est retiré dans la position fermée illustrée sur la figure 5 à partir du logement cylindrique 17 contre la force de précontrainte F par une extension supplémentaire de la bande d'élastomère 15. Le diamètre du pivot à charnière 16 est ainsi légèrement inférieur à l ' intervalle de l ' extrémité libre du tenon 20 vers la section opposée du logement cylindrique 17.To maintain free access by the cover 5 to an opening section 31 of the support 3, the connection of the cover 5 with the support 3 can be solved by the hinged arti¬ culation 13, while the hinged pivot 16 is removed in the closed position illustrated in Figure 5 from the cylindrical housing 17 against the prestressing force F by additional extension of the elastomer strip 15. The diameter of the hinge pin 16 is thus slightly less than the range of the free end of the post 20 towards the opposite section of the cylindrical housing 17.
Dans la position démontée illustrée sur la figure 4, le couvercle 5 est couplé uniquement par la bande d'élastomère 15 au niveau du support 3, moyennant quoi la bande d'élasto¬ mère 15 est détendue.In the disassembled position illustrated in FIG. 4, the cover 5 is coupled solely by the elastomer strip 15 at the level of the support 3, whereby the elastomer band 15 is relaxed.
Des éléments entiers de la structure articulée 11 selon l ' invention ainsi que du support et du couvercle peuvent être fabriqués en polypropylène, plus particulièrement moulés. Un élastomère thermoplastique (TTE) est utilisé seulement pour la bande d'élastomère 15, qui est enrobée par moulage au niveau des extrémités des parties en saillie 21, 23.Whole elements of the hinged structure 11 according to the invention as well as the support and the cover may be made of polypropylene, more particularly molded. A thermoplastic elastomer (TTE) is used only for the elastomeric strip 15, which is molded at the ends of the projections 21, 23.
Sur la figure 7, un autre mode de réalisation d'une structure couvercle-support avec une structure articulée il selon l'invention est représentée, laquelle est formée d'une paire d'articulations à charnière 13 et d'une paire de bandes d'élastomère 15 disposées conformément au mode de réalisation selon les figures 2 à 6. La structure couvercle-support se différencie de celle selon la figure 1 en ce que la bande d'élastomère 15 est disposée principalement sans être décalée latéralement par rapport à l'articulation à charnière 13 opposée.In Fig. 7, another embodiment of a cover-support structure with an articulated structure according to the invention is shown, which is formed of a pair of hinge joints 13 and a pair of webs. elastomer 15 arranged according to the embodiment according to FIGS. 2 to 6. The support-support structure is different from that of FIG. 1 in that the elastomer strip 15 is arranged mainly without being offset laterally with respect to the hinge hinge 13 opposite.
La forme fondamentale du support 3 en forme d'anneau est caractérisée par deux sections latérales 41, 43 droites parallèles l'une par rapport à l'autre, qui sont reliées l'une à l'autre par des sections en arc de cercle 45, 47. Au niveau d'une section latérale 43 droite, qui s'oppose à la section avec l'articulation à charnière 13, une zone d' actionnement 42 est renforcée, laquelle s'étend de façon courbée vers l'intérieur. Un évidement de forme complémentaire à la zone d'actionnement 42 est prévu dans le couvercle 5, de sorte qu'un utilisateur (non illustré) peut saisir la zone renforcée du support par l' évidement .The basic shape of the ring-shaped support 3 is characterized by two lateral sections 41, 43 straight parallel to each other, which are connected to each other by arcuate sections 45 , 47. At the level of a right-hand side section 43, which opposes the section with the hinge joint 13, an actuating zone 42 is reinforced, which extends curved inwards. A recess of complementary shape to the actuating zone 42 is provided in the cover 5, so that a user (not shown) can grasp the reinforced area of the support by the recess.
La structure support-couvercle selon la figure 8 se différencie de celle selon la figure 7 uniquement en ce qu'aucune zone d'actionnement renforcée n'est prévue au support 3 ainsi qu'aucun évidement au couvercle 5. De plus, au niveau de la section latérale 43 droite, principalement au milieu, un mécanisme d' encliquetage 51 particulier ayant un crochet est prévu pour verrouiller le couvercle au niveau du support, de sorte qu'une ouverture autonome du couvercle 5 est empêchée par le support 3.The support-cover structure according to FIG. 8 differs from that according to FIG. 7 only in that no reinforced operating zone is provided for the support 3 as well as no recess in the cover 5. Moreover, at the level of FIG. the right side section 43, mainly in the middle, a particular latching mechanism 51 having a hook is provided for locking the cover at the support, so that an independent opening of the cover 5 is prevented by the support 3.
La structure couvercle-support selon la figure 9 correspond essentiellement à celle de la figure 1, moyennant quoi une zone d'actionnement 42 renforcée disposée au niveau d'une section du support 3 opposée à la structure articulée 11 est prévue, laquelle est formée conformément au mode de réalisation selon la figure 7.The cover-support structure according to FIG. 9 essentially corresponds to that of FIG. 1, whereby a reinforced actuation zone 42 disposed at a section of the support 3 opposite to the articulated structure 11 is provided which is formed in accordance with FIG. in the embodiment according to Figure 7.
Sur les figures 10a-10c et 11a-11c, 12a-12c et 13a-13c, on peut voir dans quelles positions le couvercle 5 peut être placé sur la structure articulée 11 selon l'invention. Sur les figures, qui sont prévues avec la lettre a, le couvercle 5 se trouve dans une position d'ouverture démontée, dans laquelle le couvercle 5 peut être placé dans une position parallèle à la section d'ouverture 31 du support 3. Dans cette position, un accès libre au support 3 est mis à disposition.In FIGS. 10a-10c and 11a-11c, 12a-12c and 13a-13c, it can be seen in which positions the cover 5 can be placed on the articulated structure 11 according to the invention. In the figures, which are provided with the letter a, the cover 5 is in a disassembled opening position, in which the cover 5 can be placed in a position parallel to the opening section 31 of the support 3. In this position, free access to the support 3 is made available.
Sur les figures, qui sont prévues avec la lettre b, le couvercle 5 est placé dans une position d'attente verticale ouverte par rapport au support 3, de laquelle il peut passer sans étapes de montage supplémentaires à la position fermée. Sur les figures, qui sont prévues avec la lettre c, le couvercle 5 est représenté en position fermée, dans laquelle la bande d' élastomère 15 est précontrainte au maximum et le dispositif de verrouillage 7 empêche un basculement autonome du couvercle 5. Lors du relâchement du dispositif de verrouillage 7, la bande d'élastomère 15 tire le couvercle 5 en position d'attente ouverte (figures 10b, 11b, 12b et 13b) .In the figures, which are provided with the letter b, the cover 5 is placed in a vertical standby position open relative to the support 3, from which it can pass without additional mounting steps to the closed position. In the figures, which are provided with the letter c, the cover 5 is shown in the closed position, in which the elastomer strip 15 is prestressed to the maximum and the locking device 7 prevents an independent tilting of the lid 5. Upon release of the locking device 7, the elastomer strip 15 pulls the lid 5 in the open waiting position ( Figures 10b, 11b, 12b and 13b).
En relâchant en même temps le dispositif de verrouillage 7 ainsi qu'en levant le pivot à charnière 16 du logement cylindrique 17 de l'articulation à charnière 13 contre la force de précontrainte F, la position démontée représentée sur les figures 10a, lia, 12a et 13a peut être créée .By releasing the locking device 7 at the same time as well as by raising the hinge pin 16 of the cylindrical housing 17 of the hinge 13 against the prestressing force F, the disassembled position shown in FIGS. 10a, 11a, 12a and 13a can be created.
Les caractéristiques données dans la description, les figures et les revendications existantes peuvent également avoir de l ' importance individuellement ou selon une combinaison choisie pour réaliser l'invention dans les différents arrangements. The features given in the description, the figures and the existing claims may also be of importance individually or in a combination chosen to achieve the invention in the various arrangements.
