The motorization block is maintained in a driving position of the driving mechanism with an anti-rotation blocking (10) with respect to the door leaf. An independent claim is also included for a heavy hinged door, comprising a door leaf or casement.

Description

La présente invention concerne le domaine des portes battantes très lourdes et comportant au moins un battant ou vantail monté pivotant sur un dormant grâce à des paumelles et notamment des portes battantes très lourdes permettant plus particulièrement l'accès dans des environnements hostiles tels que des centrales nucléaires, et a pour objet un dispositif de paumelle motorisée pour de telles portes battantes très lourdes. Elle a également pour objet une telle porte battante très lourde équipée dudit dispositif.The present invention relates to the field of heavy hinged doors and comprising at least one leaf or leaf pivotally mounted on a frame through hinges and in particular hinged doors very heavy allowing more particularly access in hostile environments such as nuclear power plants , and relates to a motorized hinge device for such heavy hinged doors. It also relates to such a very heavy swing door equipped with said device.

On sait que les portes battante très lourdes, pesant plusieurs tonnes, sont généralement constituées par un battant ou vantail très épais et de forte charge monté sur un dormant, autour d'un axe de rotation vertical, grâce à des paumelles comprenant chacune un axe de pivotement et plus particulièrement une paumelle inférieure supportant l'essentiel de la charge dudit battant et une paumelle supérieure formant essentiellement un point anti-basculement et de guidage axial dudit battant.It is known that very heavy hinged doors, weighing several tons, are generally constituted by a very thick and heavy load wing or leaf mounted on a frame, around a vertical axis of rotation, thanks to hinges each comprising a hinge pin. pivoting and more particularly a lower hinge supporting the bulk of the load of said leaf and an upper hinge essentially forming an anti-tilt point and axial guide said leaf.

De telles paumelles sont généralement constituées par une partie de paumelle mobile solidaire du battant et par une partie de paumelle fixe solidaire du dormant, ladite partie de paumelle mobile étant montée en rotation autour de l'axe de pivotement correspondant par rapport à ladite partie de paumelle fixe. La partie de paumelle mobile forme usuellement une pièce femelle comportant un palier destiné à recevoir l'axe de pivotement par glissement ou par l'intermédiaire de roulements, tandis que ledit axe de pivotement est généralement solidaire de la partie de paumelle fixe ou intégré dans cette dernière, en étant orienté vers le haut.Such hinges are generally constituted by a movable hinge portion secured to the hinge and by a fixed hinge portion secured to the frame, said hinge portion being rotatably mounted about the pivot axis corresponding to said hinge portion fixed. The movable hinge part usually forms a female part comprising a bearing intended to receive the axis of pivoting by sliding or by means of bearings, while said pivot axis is generally integral with the hinge part fixed or integrated in this last, pointing upwards.

En outre, ces portes très lourdes nécessitent habituellement la présence d'actionneurs pour permettre le déplacement, par pivotement, en ouverture ou en fermeture des battants.In addition, these very heavy doors usually require the presence of actuators to allow movement, by pivoting, opening or closing of the leaves.

Toutefois, l'environnement hostile d'une porte très lourde, par exemple dans un bâtiment de centrale nucléaire, exige une installation et une maintenance aisée et rapide qui ne peuvent être obtenues avec les actionneurs actuels, notamment les actionneurs à bras, tels qu'ils sont mis en oeuvre sur de telles portes très lourdes. Plus particulièrement, ils ne permettent pas une interchangeabilité sans une intervention complexe et de longue durée de l'opérateur.However, the hostile environment of a very heavy door, for example in a nuclear power plant building, requires easy and quick installation and maintenance that can not be achieved with current actuators, particularly arm actuators, such as they are implemented on such very heavy doors. More particularly, they do not allow interchangeability without complex and long-term operator intervention.

En outre, les actionneurs actuels sont d'un prix relativement élevé et occupent un volume fonctionnel important qui rend leur installation difficile, voire impossible, sur des portes très lourdes dont l'environnement est très restreint, ce qui est le cas notamment des portes très lourdes installées dans les bâtiments des centrales nucléaires.In addition, the current actuators are relatively expensive and occupy a large functional volume that makes their installation difficult or impossible on very heavy doors whose environment is very limited, which is particularly the case of doors very installed in the buildings of nuclear power plants.

Le document WO 2007/012965 a pour objet un système de charnière motorisée pour vantaux de portes ou pour volets, notamment en bois ou en aluminium, comportant une aile fixe avec un pivot à charnière, une aile mobile, un moto-réducteur fixé sur un axe de pivotement, solidaire de l'aile fixe, par sa face supérieure au moyen d'une pluralité de vis, tandis que l'axe d'entraînement du moto-réducteur fixé sur ladite aile fixe traverse cette dernière en s'étendant jusque dans un axe solidaire de l'aile mobile et traversant coaxialement ledit axe de pivotement, en vue de permettre l'entraînement en rotation de l'aile mobile autour dudit axe de pivotement.The document WO 2007/012965 relates to a motorized hinge system for door leaves or shutters, in particular of wood or aluminum, comprising a fixed wing with a hinged pivot, a movable wing, a geared motor fixed on a pivot axis, integral with the fixed wing, by its upper face by means of a plurality of screws, while the drive shaft of the geared motor fixed on said fixed wing crosses the latter extending into an axis integral with the mobile wing and coaxially traversing said pivot axis, to allow the rotational drive of the movable wing about said pivot axis.

Toutefois, si ce type de motorisation convient pour les portes ou volets classiques, celui-ci n'est pas adapté pour les portes très lourdes, notamment dans des environnements hostiles tels que les centrales nucléaires exigeant des opérations de maintenance et d'interchangeabilité aisée et de courte durée. En effet, la fixation du moto-réducteur sur l'aile fixe au moyen d'une multiplicité de vis assurant la fixation du moto-réducteur et son blocage en rotation nécessite des outils spécifiques et ne permet pas une fixation et une libération rapide dudit moto-réducteur, avec un minimum de contrainte. En outre, la fixation du moto-réducteur sous l'aile fixe nécessite son maintien lors du vissage, ce qui ajoute encore une contrainte supplémentaire à l'opérateur rendant très difficile, voire impossible, son changement dans de tels environnements sensibles.However, if this type of motorization is suitable for conventional doors or shutters, it is not suitable for very heavy doors, especially in hostile environments such as nuclear power plants requiring maintenance operations and easy interchangeability and of short time. Indeed, the attachment of the geared motor on the fixed wing by means of a multiplicity of screws ensuring the attachment of the geared motor and its locking in rotation requires specific tools and does not allow fixing and quick release of said motorcycle -reducer, with a minimum of constraint. In addition, fixing the geared motor under the fixed wing requires its retention during screwing, which adds another constraint to the operator making it very difficult or impossible to change in such sensitive environments.

La présente invention a pour but de pallier ces inconvénients en proposant un dispositif de paumelle motorisée adaptable sur une porte très lourde et permettant une installation et des interventions de maintenance ou d'interchangeabilité aisées et de courte durée, avec un minimum de contrainte, des moyens d'actionnement du déplacement du battant.The present invention aims to overcome these disadvantages by proposing a motorized hinge device adaptable to a very heavy door and allowing installation and maintenance interventions or interchangeability easy and short-term, with a minimum of constraints, means actuating movement of the wing.

A cet effet, la présente invention a pour objet un dispositif de paumelle motorisée pour porte battante très lourde destinée à être motorisée et étant constituée par au moins un battant ou vantail monté pivotant, autour d'un axe de rotation sensiblement vertical, sur un dormant, ledit dispositif comprenant une partie de paumelle fixe solidaire dudit dormant et une partie de paumelle mobile solidaire dudit battant et montée en rotation par rapport à ladite partie de paumelle fixe autour d'un axe de pivotement, ladite partie de paumelle mobile comportant un mécanisme d'entraînement mû par un bloc de motorisation, comportant de préférence un motoréducteur, apte à entraîner en rotation ladite partie de paumelle mobile autour de son axe de pivotement et, partant, à déplacer, par pivotement, en ouverture ou en fermeture, ledit battant, ledit bloc de motorisation étant monté de manière amovible sur ledit mécanisme d'entraînement et sur la partie de paumelle fixe et se caractérise essentiellement en ce que ledit bloc de motorisation est fixé sur la partie de paumelle fixe grâce à des moyens de fixation et de libération rapides en étant maintenu en position d'entraînement dudit mécanisme d'entraînement avec blocage anti-rotation dudit bloc par rapport au battant, éventuellement avec un jeu radial.For this purpose, the subject of the present invention is a motorized hinge device for a very heavy hinged door intended to be motorized and consisting of at least one flap or wing pivotally mounted about a substantially vertical axis of rotation on a frame , said device comprising a fixed hinge portion secured to said frame and a movable hinge portion secured to said leaf and rotatably mounted by relative to said fixed hinge portion about a pivot axis, said movable hinge portion having a drive mechanism driven by a motorization unit, preferably having a geared motor adapted to rotate said movable hinge portion around its pivot axis and thereby to move, by pivoting, opening or closing, said leaf, said motor block being removably mounted on said drive mechanism and on the fixed hinge portion and is characterized essentially in that said motor unit is fixed on the fixed hinge part by means of fast fixing and release means while being held in the driving position of said drive mechanism with anti-rotation blocking of said block relative to the leaf, possibly with a radial clearance.

La présente invention a également pour objet une porte très lourde motorisée et comportant au moins un battant ou vantail monté pivotant, autour d'un axe de rotation sensiblement vertical, sur un dormant par l'intermédiaire d'au moins une paumelle inférieure et d'au moins une paumelle supérieure, ladite porte très lourde, se caractérisant essentiellement en ce qu'au moins une paumelle inférieure consiste en un dispositif de paumelle motorisée selon la présente invention.The present invention also relates to a very heavy motorized door and comprising at least one leaf or leaf pivotally mounted about a substantially vertical axis of rotation, on a frame through at least one lower hinge and d ' at least one upper hinge, said heavier door, characterized essentially in that at least one lower hinge consists of a motorized hinge device according to the present invention.

Comme on peut le voir clairement sur les figures annexées, le bloc de motorisation 7 peut être monté de préférence sur la face supérieure de la partie de paumelle fixe 3, en reposant plus particulièrement sur celle-ci.As can be seen clearly in the accompanying figures, the motor unit 7 can be mounted preferably on the upper face of the fixed hinge portion 3, resting more particularly thereon.

De préférence, le bloc de motorisation 7 peut comporter un moyeu d'entraînement 12 et le mécanisme d'entraînement peut consister en un arbre d'entraînement 6 prolongeant la partie de paumelle mobile 4, coaxialement à son axe de pivotement 5, ledit arbre d'entraînement 6 étant mû en rotation axiale par ledit moyeu d'entraînement 12 du bloc de motorisation 7 grâce à des moyens de liaison et d'entraînement en rotation 8, 11 (figure 4 et figure 9).Preferably, the motor unit 7 may comprise a drive hub 12 and the drive mechanism may consist of a drive shaft 6 extending the mobile hinge part 4, coaxially with its pivot axis 5, said drive shaft. 6 training being moved in axial rotation by said drive hub 12 of the motor unit 7 by means of connecting and rotating means 8, 11 ( figure 4 and figure 9 ).

De préférence, les moyens de liaison et d'entraînement en rotation peuvent consister en une ou plusieurs clavettes 8 fixées sur ledit arbre d'entraînement 6, en étant par exemple fixées chacune longitudinalement sur la face externe dudit arbre 6 (figure 9), et en venant s'engager chacune dans une rainure de clavette 11 (figure 4) pratiquée dans le moyeu d'entraînement 12 du bloc de motorisation 6, ce de manière à transmettre le couple moteur à l'arbre d'entraînement 6 au travers de ladite clavette 8 correspondante.Preferably, the connection and rotary drive means may consist of one or more keys 8 fixed on said drive shaft 6, for example being each fixed longitudinally on the outer face of said shaft 6 ( figure 9 ), and coming each engage in a keyway 11 ( figure 4 ) made in the drive hub 12 of the motor unit 6, so as to transmit the motor torque to the drive shaft 6 through said corresponding key 8.

On peut voir également sur la figure 2 et sur la figure 4 que le moyeu d'entraînement 12 entraîné en rotation axiale par le motoréducteur 7' s'étend en traversant une avancée 7" du bloc de motorisation 7, par rapport à la partie dudit bloc 7 comportant la partie moteur, de manière à pouvoir implanter aisément et rapidement ledit bloc de motorisation 7 sur l'arbre d'entraînement 6 de la partie de paumelle mobile 4.We can also see on the figure 2 and on the figure 4 that the drive hub 12 driven in axial rotation by the geared motor 7 'extends through an advance 7 "of the motorization unit 7, relative to the portion of said block 7 comprising the motor part, so as to be able to implement easily and quickly said motor block 7 on the drive shaft 6 of the movable hinge portion 4.

L'avancée 7" peut être profilée, de préférence en forme globalement de parallélépipède rectangle, de manière à présenter deux faces opposées, respectivement inférieure et supérieure, traversées sensiblement perpendiculairement par ledit moyeu d'entraînement 12 qui débouche alors sur lesdites faces opposées par deux ouvertures respectivement inférieure 12' (figure 7) et supérieure 12" (figure 4), ce afin de permettre, d'une part, l'introduction de l'arbre d'entraînement 6 dans ledit moyeu d'entraînement 12 de préférence à travers l'ouverture inférieure 12', appelée ci-après ouverture d'introduction 12' et, d'autre part, le maintien avec blocage axial de l'arbre d'entraînement 6 dans ledit moyeu d'entraînement 12 grâce à une butée 6', telle qu'une rondelle, fixée, par exemple au moyen d'une vis 6", et donc par nature de façon amovible, sur la partie de l'extrémité libre dudit arbre d'entraînement 6 dépassant de l'autre face opposée, et venant en appui contre la surface externe de ladite face (figure 2) en empêchant tout retrait dudit arbre d'entraînement 6 hors dudit moyeu d'entraînement 12.The advance 7 "may be profiled, preferably in the form of a generally rectangular parallelepiped, so as to have two opposite faces, respectively lower and upper, traversed substantially perpendicularly by said drive hub 12 which then opens on said faces opposite by two openings respectively lower 12 '( figure 7 ) and upper 12 "( figure 4 ), in order to allow, on the one hand, the introduction of the drive shaft 6 into said drive hub 12 preferably through the lower opening 12 ', hereinafter referred to as the feed opening 12 and, on the other hand, the holding with axial locking of the drive shaft 6 in said drive hub 12 by means of a stop 6 ', such as a washer, fixed, for example by means of a screw 6 ", and thus by nature removably, on the part of the free end of said drive shaft 6 protruding from the other opposite face, and bearing against the outer surface of said face ( figure 2 ) by preventing any withdrawal of said drive shaft 6 from said drive hub 12.

De préférence, le bloc de motorisation 7 peut avantageusement être fixé, de manière amovible, avec blocage anti-rotation, sur la partie de paumelle fixe 3 par l'intermédiaire d'une pièce de liaison 9 fixée sur ledit bloc de motorisation 7 et comportant une partie de liaison 13 assurant la liaison mécanique avec ladite partie de paumelle fixe 3 par l'intermédiaire d'un axe ou doigt de liaison et de blocage anti-rotation 10 fixé sur cette dernière, la liaison mécanique entre la partie de liaison 13 et ledit doigt étant, de préférence, une liaison mécanique avec jeu radial apte à conférer un degré de liberté audit bloc 7 autorisant des déplacements éventuels et de faible ampleur de ce dernier, lors de l'ouverture ou de la fermeture du battant 1 (figure 2, figure 3, figure 7 et figure 8).Preferably, the motorization unit 7 can advantageously be removably fixed with anti-rotation locking on the fixed hinge portion 3 by means of a connecting piece 9 fixed to said motor unit 7 and comprising a connecting portion 13 providing the mechanical connection with said fixed hinge portion 3 via an axis or connecting finger and anti-rotation locking 10 fixed on the latter, the mechanical connection between the connecting portion 13 and said finger being, preferably, a mechanical connection with radial clearance capable of conferring a degree of freedom block 7 enabling possible small movements of the latter, when opening or closing the wing 1 ( figure 2 , figure 3 , Figure 7 and Figure 8 ).

La pièce de liaison 9 recevant le doigt de liaison et de blocage anti-rotation 10 en vue de permettre la fixation amovible du bloc de motorisation 7, tout en empêchant la rotation dudit bloc par rapport au battant 1, sur une partie fixe du dormant 2 et plus particulièrement sur la partie de paumelle fixe 3 ainsi que l'arbre d'entraînement 6 prolongeant la partie de paumelle mobile 4 en vue de son introduction dans le moyeu 12 du bloc de motorisation 7, permet une interchangeabilité aisée et de courte durée de ce dernier que n'offre pas les systèmes actuels qui ne comporte pas de tels moyens de fixation et de libération rapides dudit bloc à la fois sur la partie de paumelle mobile et sur la partie de paumelle fixe.The connecting piece 9 receiving the connecting finger and anti-rotation locking 10 to allow the removable attachment of the motor unit 7, while preventing the rotation of said block relative to the wing 1, on a fixed part of the frame 2 and more particularly on the fixed hinge portion 3 and the drive shaft 6 extending the movable hinge part 4 for insertion into the hub 12 of the motor unit 7, allows easy interchangeability and short-term the latter that does not offer current systems that does not include such means for fast fixing and release of said block both on the movable hinge portion and on the fixed hinge portion.

Dans un mode de réalisation préférentiel de la présente invention, la pièce de liaison 9 peut être fixée avantageusement sous le bloc de motorisation 7 et en partie en regard de l'ouverture d'introduction 12' de l'arbre d'entraînement 6 dans le moyeu d'entraînement 12 (figure 7 et figure 8).In a preferred embodiment of the present invention, the connecting piece 9 can be advantageously fixed under the motorization block 7 and partly opposite the insertion opening 12 'of the drive shaft 6 in the drive hub 12 ( Figure 7 and Figure 8 ).

On comprendra alors que la partie de liaison 13 constitue une extension latérale de la partie de la pièce de liaison 9 située en regard de ladite ouverture d'introduction 12'.It will be understood that the connecting portion 13 constitutes a lateral extension of the portion of the connecting piece 9 located opposite said insertion opening 12 '.

La présente invention peut prévoir que le doigt de liaison et de blocage anti-rotation 10 présente une forme allongée, préférentiellement globalement cylindrique, et soit relié mécaniquement par l'une de ses extrémités libres à la partie de liaison 13 de la pièce de liaison 9 et fixé par son autre extrémité libre sur la face externe de la partie de paumelle fixe 3, en s'étendant sensiblement parallèlement à l'axe de rotation 1' du battant 1, distinctement de la partie de paumelle mobile 4.The present invention may provide that the anti-rotation connecting and locking finger 10 has an elongated shape, preferably substantially cylindrical, and is mechanically connected by one of its free ends to the connecting portion 13 of the connecting piece 9 and fixed by its other free end to the outer face of the fixed hinge portion 3, extending substantially parallel to the axis of rotation 1 'of the flap 1, distinctly from the movable hinge part 4.

De préférence, la partie de paumelle fixe 3 peut présenter une structure profilée de forme globalement cylindrique d'axe sensiblement vertical et le doigt de liaison et de blocage anti-rotation 10 peut être fixé sur la face supérieure de ladite partie de paumelle fixe 3 en s'étendant sensiblement perpendiculairement à cette dernière, comme on peut le voir notamment sur la figure 2 et sur la figure 3.Preferably, the fixed hinge portion 3 may have a profiled structure of generally cylindrical shape with a substantially vertical axis and the anti-rotation connecting and locking finger 10 may be fixed on the upper face of said fixed hinge portion 3 in extending substantially perpendicular to the latter, as can be seen in particular in the figure 2 and on the figure 3 .

De préférence, comme on peut le voir sur la figure 7, la pièce de liaison 9 peut être réalisée sous la forme d'une plaque fixée sous le bloc de motorisation 7 et en partie en regard de l'ouverture d'introduction 12' de l'arbre d'entraînement 6 dans le moyeu d'entraînement 12. Ladite pièce de liaison 9 en forme de plaque peut s'étendre avantageusement dans un plan sensiblement perpendiculaire à l'axe 12"' du moyeu d'entraînement 12 et peut comporter, d'une part, une première lumière 9' apte à être traversée par ledit arbre d'entraînement 6 de la partie de paumelle mobile 4 en vue de permettre la liaison mécanique en entraînement dudit arbre d'entraînement 6 avec ledit moyeu d'entraînement 12 et, d'autre part, d'une deuxième lumière 9" apte à recevoir une partie de l'extrémité libre correspondante du doigt de liaison et de blocage anti-rotation 10 (figure 4) en vue d'assurer la liaison mécanique de ladite pièce de liaison 9 avec ledit doigt 10, ce afin d'assurer un blocage anti-rotation du bloc de motorisation 7, notamment autour de l'axe 12"' du moyeu d'entraînement 12.Preferably, as can be seen on the figure 7 , the connecting piece 9 can be made in the form of a plate fixed under the motorization block 7 and partly opposite the insertion opening 12 'of the drive shaft 6 in the hub of drive 12. Said connecting piece 9 in the form of a plate may advantageously extend in a plane substantially perpendicular to the axis 12 "'of the drive hub 12 and may comprise, on the one hand, a first light 9' fit to be traversed by said drive shaft 6 of the movable hinge portion 4 to allow the mechanical connection drive of said drive shaft 6 with said drive hub 12 and secondly a second 9 "light adapted to receive a portion of the corresponding free end of the connecting finger and anti-rotation lock 10 ( figure 4 ) in order to ensure the mechanical connection of said connecting piece 9 with said finger 10, in order to ensure an anti-rotation blocking of the motor unit 7, in particular around the axis 12 "'of the drive hub 12.

Si on se réfère à la figure 7 et à la figure 8, on peut voir que la pièce de liaison 9 en forme de plaque est fixée sous le bloc de motorisation 7 grâce à des vis 9IV, réparties de préférence autour de la première ouverture 9', permettant de serrer ladite pièce de liaison 9 contre la face inférieure 7"' dudit bloc de motorisation 7.If we refer to the figure 7 and at the figure 8 it can be seen that the connecting piece 9 in the form of a plate is fixed under the motorization unit 7 by means of screws 9 IV , distributed preferably around the first opening 9 ', making it possible to clamp the said connecting piece 9 against the lower face 7 "'of said motor unit 7.

La pièce de liaison 9, fixée sur le bloc de motorisation 7 et connectée mécaniquement au doigt de liaison et de blocage anti-rotation 10 solidaire d'un point fixe de la porte très lourde concernée et de préférence de la partie de paumelle fixe 3, est ainsi bloqué en rotation autour de l'axe 12"' du moyeu d'entraînement 12, ce qui a pour effet d'empêcher toute rotation dudit bloc de motorisation 7, notamment autour dudit axe 12"'.The connecting piece 9, fixed on the motor unit 7 and mechanically connected to the connecting finger and anti-rotation blocking 10 secured to a fixed point of the very heavy door concerned and preferably the fixed hinge portion 3, is thus locked in rotation about the axis 12 "'of the drive hub 12, which has the effect of preventing any rotation of said motor unit 7, especially around said axis 12"'.

On comprendra qu'en situation de fonctionnement, lorsque le motoréducteur 7' est alimenté, celui-ci est apte à entraîner le moyeu d'entraînement 12 qui entraîne alors en rotation axiale l'arbre d'entraînement 6, de préférence claveté, solidaire de la partie de paumelle mobile 4 et, partant, le pivotement, en ouverture ou en fermeture, du battant 1 solidaire en rotation de ladite partie de paumelle mobile 4.It will be understood that, in an operating situation, when the gearmotor 7 'is energized, it is able to drive the drive hub 12 which then drives in axial rotation the drive shaft 6, preferably keyed, integral with the movable hinge part 4 and thus the pivoting, in opening or closing, of the leaf 1 integral in rotation with said mobile hinge part 4.

On comprendra également qu'un bloc de motorisation 7 amovible mis en oeuvre dans le dispositif de paumelle selon la présente invention est maintenu, avec blocage anti-rotation, en position d'entraînement en rotation de la partie de paumelle mobile 4 et, partant, du battant 1 de la porte très lourde concernée, d'une part, en étant implanté fonctionnellement sur l'arbre d'entraînement 6 solidaire en rotation de la partie de paumelle mobile 4 et, d'autre part, en étant bloqué en rotation autour de l'axe 12"' du moyeu d'entraînement 12 par l'intermédiaire de la pièce de liaison 9 recevant le doigt de liaison et de blocage anti-rotation 10 solidaire de la partie de paumelle fixe 3.It will also be understood that a removable motor unit 7 used in the hinge device according to the present invention is maintained, with anti-rotation lock, in the rotational driving position of the mobile hinge part 4 and hence of the wing 1 of the very heavy door concerned, on the one hand, while being implanted functionally on the drive shaft 6 integral in rotation with the movable hinge portion 4 and, secondly, being locked in rotation about the axis 12 "'of the drive hub 12 via the connecting piece 9 receiving the connecting finger and anti-rotation locking 10 secured to the fixed hinge part 3.

D'autre part, la présente invention peut prévoir avantageusement que la deuxième lumière 9" présente une forme oblongue, d'axe longitudinal 9"' passant sensiblement par l'axe 12'" du moyeu d'entraînement 12 du bloc de motorisation 7, de préférence de largeur sensiblement égale au diamètre de la partie de l'extrémité libre correspondante du doigt de liaison et de blocage anti-rotation 10 globalement cylindrique la traversant. Ladite partie de l'extrémité libre traversant ladite deuxième lumière 9" oblongue est apte à coulisser librement dans cette dernière, ce de manière à lui conférer un jeu radial ou degré de liberté de déplacement radial dans le sens de la longueur de ladite deuxième lumière 9" oblongue (figure 7) permettant d'autoriser des déplacements radiaux éventuels et de faible ampleur dudit bloc de motorisation 7, lors de l'ouverture ou de la fermeture du battant 1.On the other hand, the present invention can advantageously provide that the second lumen 9 "has an oblong shape, of longitudinal axis 9"'passing substantially through the axis 12'"of the drive hub 12 of the motor unit 7, preferably of width substantially equal to the diameter of the portion of the corresponding free end of the generally cylindrical anti-rotation connecting and locking finger therethrough.said portion of the free end passing through said second oblong slot 9 is adapted to slide freely in the latter, so as to give it a radial clearance or degree of freedom of radial displacement in the direction of the length of said second oblong slot 9 "( figure 7 ) allowing to allow possible radial movements and small magnitude of said motor unit 7, when opening or closing the wing 1.

Enfin, la présente invention peut prévoir que l'axe de pivotement 5 peut être solidaire de la partie de paumelle fixe 3 et que la partie de paumelle mobile 4 peut être constituée par une platine de support 14 destinée à être fixée sur le battant 1, par exemple grâce à des vis 14', et se prolongeant par un bras 15 portant à son extrémité libre un embout 16, de préférence de forme globalement cylindrique, comportant une cavité de réception ou palier 16' destinée à recevoir l'axe de pivotement 5 de la partie de paumelle mobile 4 (figure 2, figure 3 et figure 9).Finally, the present invention can provide that the pivot axis 5 can be integral with the fixed hinge portion 3 and that the movable hinge portion 4 can be constituted by a support plate 14 intended to be fixed on the leaf 1, for example by means of screws 14 ', and extending by an arm 15 carrying at its free end a tip 16, preferably of generally cylindrical shape, having a receiving cavity or bearing 16' intended to receive the pivot axis 5 of the mobile hinge part 4 ( figure 2 , figure 3 and figure 9 ).

En outre le bras 15 peut s'étendre avantageusement en s'écartant du plan du battant 1, comme on peut le voir par exemple sur la figure 3, de manière à créer un espace ou dégagement suffisant permettant de loger et de mettre en oeuvre le bloc de motorisation 7, tandis que l'axe de pivotement 5 peut avantageusement être monté sur la partie de paumelle fixe 3 (figure 2 et figure 3).In addition, the arm 15 may extend advantageously away from the plane of the wing 1, as can be seen for example on the figure 3 , so as to create a space or clearance sufficient to accommodate and implement the motorization unit 7, while the pivot axis 5 can advantageously be mounted on the fixed hinge part 3 ( figure 2 and figure 3 ).

De préférence, l'arbre d'entraînement 6 de la partie de paumelle mobile 4 peut être fixé sur la face supérieure de l'embout 16 par l'intermédiaire d'un capot 17 de forme globalement cylindrique comportant une base élargie formant une couronne de fixation 18 pour sa liaison avec blocage en rotation sur ledit embout 16, de préférence par vissage de ladite couronne 18 sur ladite face supérieure de ce dernier et plus particulièrement par vissage de vis 19 espacées régulièrement sur toute la circonférence de ladite couronne 18 (figure 2, figure 3 et figure 9).Preferably, the drive shaft 6 of the movable hinge part 4 can be fixed on the upper face of the end piece 16 by means of a cover 17 of generally cylindrical shape having an enlarged base forming a crown of fixing 18 for its connection with rotational locking on said tip 16, preferably by screwing said 18 on said upper face of the latter and more particularly by screwing screws 19 regularly spaced over the entire circumference of said ring 18 ( figure 2 , figure 3 and figure 9 ).

La présente invention a également pour objet, comme on peut le voir notamment sur la figure 1, une porte très lourde motorisée comportant au moins un battant ou vantail 1 monté pivotant, autour d'un axe de rotation 1' sensiblement vertical, sur un dormant 2 par l'intermédiaire d'une paumelle inférieure 3, 4 et d'au moins une paumelle supérieure, non représentée, dont au moins une paumelle inférieure 3, 4 consiste en un dispositif de paumelle motorisée selon la présente invention.The subject of the present invention is also, as can be seen in particular on the figure 1 a very heavy motorized door having at least one leaf or leaf 1 pivotally mounted around a substantially vertical axis of rotation 1 ', on a frame 2 via a lower hinge 3, 4 and at least an upper hinge, not shown, of which at least one lower hinge 3, 4 consists of a motorized hinge device according to the present invention.

En outre, la présente invention peut prévoir un arrangement préférentiel dans lequel le bloc de motorisation 7 peut avantageusement occuper un espace contigü audit dormant 2, au niveau de l'axe de rotation 1' du battant 1, entre la ou les paumelle(s) inférieure(s) 3, 4 et la ou les paumelle(s) supérieure(s) de ladite porte, c'est-à-dire sensiblement dans l'alignement des paumelles respectivement inférieure et supérieure(s), ceci dans le but d'obtenir un encombrement limitée du bloc de motorisation et une mise en oeuvre à un emplacement ne demandant aucun travaux dans le dormant ou dans la dalle logeant ladite porte. Un tel arrangement répond ainsi parfaitement aux contraintes liées à l'environnement restreint, voire hostile, d'une telle porte, et notamment d'une porte permettant l'accès à un espace clos dans un bâtiment de centrale nucléaire.In addition, the present invention may provide a preferred arrangement in which the motorization unit 7 may advantageously occupy a space contiguous to said frame 2, at the axis of rotation 1 'of the leaf 1, between the hinge (s) lower (s) 3, 4 and the upper hinge (s) of said door, that is to say substantially in the alignment of the hinge respectively lower and upper (s), this for the purpose of obtain a limited size of the engine block and an implementation at a location that requires no work in the frame or in the slab housing said door. Such an arrangement thus perfectly meets the constraints related to the restricted environment, even hostile, of such a door, including a door allowing access to an enclosed space in a nuclear power plant building.

On notera que dans un tel dispositif de paumelle motorisée consistant en au moins une paumelle inférieure, le guidage en rotation de la partie de paumelle mobile 4 par rapport à la partie de paumelle fixe 3 de chaque dite paumelle inférieure, autour de son axe de pivotement 5 peut avantageusement être réalisé par interposition de moyens de roulement radiaux destinés à supporter principalement des charges radiales et de moyens de roulement axiaux destinés à supporter principalement les charges axiales, lesdits moyens de roulement étant aptes à autoriser un défaut angulaire de coaxialité de ladite partie de paumelle fixe par rapport à ladite partie de paumelle mobile, comme cela est décrit dans la demande de brevet française n° 09 57975 au nom de la présente demanderesse.Note that in such a motorized hinge device consisting of at least one lower hinge, the rotational guidance of the movable hinge portion 4 relative to the fixed hinge portion 3 of each said lower hinge, about its pivot axis 5 can advantageously be achieved by interposition of radial rolling means intended to support mainly radial loads and axial rolling means intended to support mainly the axial loads, said rolling means being able to allow an angular defect of coaxiality of said portion of fixed hinge relative to said movable hinge portion, as described in French patent application no. 09 57975 on behalf of the plaintiff.

Dans ce dernier cas et pour une porte très lourde comprenant au moins une paumelle supérieure, chaque dite paumelle supérieure, conformément à la demande de brevet française précitée, peut avantageusement comprendre des moyens de roulement radiaux destinés à supporter principalement les charges radiales et étant aptes à autoriser un défaut angulaire de coaxialité de sa partie de paumelle fixe par rapport à sa partie de paumelle mobile.In the latter case and for a very heavy door comprising at least one upper hinge, each said upper hinge, in accordance with the aforementioned French patent application, may advantageously comprise radial rolling means for to support mainly radial loads and being able to allow an angular defect of coaxiality of its fixed hinge portion relative to its movable hinge portion.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
