Description

L'invention concerne un dispositif de commande électromécanique pour porte basculante, notamment pour porte basculante de garage composée d'un ouvrant équilibré par des contre-poids latéraux reliés audit ouvrant par des câbles ou chaînes s'enroulant, partiellement, autour de poulies ou pignons dentés entraînés par l'intermédiaire de moyens de transmission coopérant avec des moyens d'entraînement d'un ensemble moto-réducteur.The invention relates to an electromechanical control device for an overhead door, in particular for an overhead garage door, comprising an opening balanced by lateral counterweights connected to said opening by cables or chains that are partially wound around pulleys or pinions. toothed driven by means of transmission cooperating with drive means of a geared motor assembly.

La présente Invention trouvera son application dans le domaine de la menuiserie du bâtiment et, plus particulièrement, chez les fabricants de portes basculantes, notamment de portes de garage.The present invention will find its application in the field of building joinery and, more particularly, in the manufacturers of tilting doors, in particular garage doors.

En fait, l'on connaît déjà des dispositifs de commande électromécanique pour porte basculante notamment pour porte basculante de garage correspondant à la description ci-dessus.In fact, electromechanical control devices are already known for tilting door, in particular for garage tilting door corresponding to the description above.

Ainsi, un tel dispositif est notamment décrit dans le document EP-B-0.089.909.Thus, such a device is described in particular in document EP-B-0.089.909.

Ainsi, ce dispositif de commande électromécanique connu au travers de ce document antérieur s'applique, plus particulièrement, à des portes basculantes de garage comportant un dormant composé de deux montants reliés à leur partie supérieure par un linteau placé horizontalement, ainsi qu'un ouvrant basculant guidé par l'intermédiaire de tétons de guidage ou similaires se déplaçant dans des rails verticaux aménagés, précisément, dans les montants du dormant. Cet ouvrant est, par ailleurs, équilibré au moyen de contre-poids latéraux coulissant dans des glissières verticales se situant, éventuellement, à hauteur des montants du dormant. En fait, ces contre-poids sont reliés à l'ouvrant par l'intermédiaire de câbles ou chaînes s'enroulant, partiellement, autour de poulies ou pignons dentés entraînés, précisément, au moyen du dispositif de commande électromécanique.Thus, this electromechanical control device known through this prior document applies, more particularly, to overhead garage doors comprising a frame made up of two uprights connected to their upper part by a lintel placed horizontally, as well as an opening tilting guided by means of guide pins or the like moving in vertical rails arranged, precisely, in the uprights of the frame. This opening is, moreover, balanced by means of lateral counterweights sliding in vertical slides situated, possibly, at the height of the uprights of the frame. In fact, these counterweights are connected to the opening by means of cables or chains which are partially wound around pulleys or toothed pinions driven, precisely, by means of the electromechanical control device.

Celui-ci consiste, plus précisément, en un ensemble moteur électrique réducteur fixé au moyen de supports sur le linteau du dormant.This consists, more precisely, of a reducing electric motor assembly fixed by means of supports on the lintel of the frame.

Ce moto-réducteur comporte un pignon moteur lequel entraîne un pignon mené disposé à l'une des extrémités d'un temporisateur mécanique. Ce dernier a pour fonction de provoquer un décalage de la phase d'ouverture et/ou de fermeture de l'ouvrant par rapport à la phase de déverrouillage et/ou de verrouillage. Plus précisément, au moyen de ce temporisateur mécanique, l'on obtient, notamment en cas de commande d'ouverture de la porte basculante, un décalage entre le moment où le moteur électrique est d'activité et celui où les moyens de transmission, reliés aux poulies ou pignons dentés, sont entraînés. Il convient, en effet, d'assurer préalablement à cette ouverture, le déverrouillage de l'ouvrant. Bien sûr, lors de la fermeture, ce décalage se produit dans l'autre sens dans la mesure où les moyens de transmission cessent d'être entraînés lorsque l'ouvrant est amené en contact avec le dormant, alors que le moto-réducteur continue à fonctionner en vue d'actionner les moyens de verrouillage.This gear motor comprises a motor pinion which drives a driven pinion arranged at one end of a mechanical timer. The latter has the function of causing a shift in the opening and / or closing phase of the opening with respect to the unlocking and / or locking phase. More precisely, by means of this mechanical timer, there is obtained, in particular in the event of an opening control of the overhead door, a time lag between the moment when the electric motor is active and that when the transmission means, connected pulleys or toothed gears are driven. It is indeed necessary to ensure, prior to this opening, the unlocking of the opening. Of course, when closing, this offset occurs in the other direction insofar as the transmission means cease to be driven when the door is brought into contact with the frame, while the gear motor continues to operate in order to actuate the locking means.

Quant au temporisateur mécanique, celui-ci se compose d'un élément tubulaire placé parallèlement au moto-réducteur et renfermant un élément élastique, tel qu'un ressort hélicoïdal qui, lorsqu'il est au repos présente un diamètre extérieur sensiblement égal au diamètre interne dudit élément tubulaire. Par ailleurs, l'une des extrémités de ce ressort hélicoïdal est rendue solidaire du pignon mené coopérant avec le pignon moteur du moto-réducteur, tandis que l'autre extrémité est rendue solidaire en rotation, par l'intermédiaire de moyens appropriés, dudit élément tubulaire.As for the mechanical timer, it consists of a tubular element placed parallel to the gear motor and containing an elastic element, such as a helical spring which, when at rest has an outside diameter substantially equal to the internal diameter of said tubular element. Furthermore, one end of this helical spring is made integral with the driven pinion cooperating with the motor pinion of the gear motor, while the other end is made integral in rotation, by appropriate means, of said element. tubular.

A noter, en outre, que ce temporisateur mécanique est traversé, de part en part, par un arbre d'entraînement sur lequel est monté, libre en rotation, le pignon mené tandis que l'élément tubulaire est, lui, rendu solidaire de cet arbre d'entraînement. Celui-ci constitue, en partie les moyens de transmission venant à coopérer avec les poulies ou pignons dentés.Note, moreover, that this mechanical timer is traversed, right through, by a drive shaft on which is mounted, free to rotate, the pinion driven while the tubular element is itself made integral with this drive shaft. This constitutes, in part, the transmission means coming to cooperate with the pulleys or toothed pinions.

Ainsi, le fonctionnement de ce dispositif connu est le suivant:
Si l'on considère que l'ouvrant est en train de se fermer et qu'il vient à buter contre le linteau du dormant, cet ouvrant est immobilisé, et le moto-réducteur continue à être activé, il s'en suit que l'élément tubulaire du temporisateur mécanique est bloqué, alors que le pignon mené est encore entraîné conduisant à la mise sous tension de l'élément élastique. En fait, cette rotation complémentaire du moto-réducteur a pour conséquence le verrouillage de la porte basculante par l'intermédiaire de moyens appropriés actionnés, précisément, pendant cette phase par ledit moto-réducteur.
Thus, the operation of this known device is as follows:
If we consider that the sash is closing and that it abuts against the lintel of the frame, this sash is immobilized, and the gear motor continues to be activated, it follows that the 'element tubular mechanical timer is blocked, while the driven pinion is still driven leading to the tensioning of the elastic element. In fact, this complementary rotation of the gear motor results in the locking of the tilting door by means of appropriate means actuated, precisely, during this phase by said gear motor.

Les inconvénients rencontrés au travers de ce dispositif de commande électromécanique connu sont de deux ordres. Tout d'abord ce dispositif n'est pas en mesure de garantir un verrouillage parfait de l'ouvrant contre le dormant dans la mesure où, si l'ouvrant rencontre un obstacle l'empêchant de venir, parfaitement, en applique contre le dormant, le moto-réducteur vient à actionner les moyens de verrouillage sans que ceux-ci puissent, réellement, coopérer avec l'ouvrant. Ainsi, l'expérience a démontré qu'un vent d'une moindre puissance était en mesure de gêner, précisément, cette opération de verrouillage.The drawbacks encountered through this known electromechanical control device are twofold. First of all, this device is not able to guarantee perfect locking of the door against the frame, since, if the door encounters an obstacle preventing it from coming, perfectly, applied against the frame, the gear motor comes to actuate the locking means without the latter being able to actually cooperate with the opening. Thus, experience has shown that a less powerful wind was able to hinder, precisely, this locking operation.

En outre, étant donné que le temporisateur mécanique fait intervenir un ressort que le moto-réducteur se doit de mettre sous tension à chaque fermeture et verrouillage de l'ouvrant basculant, le moteur électrique, proprement dit, doit disposer d'une puissance largement supérieure à la puissance réellement nécessaire pour ouvrir et fermer la porte, sachant que l'ouvrant est équilibré.In addition, given that the mechanical timer involves a spring which the gear motor must put under tension at each closing and locking of the tilting leaf, the electric motor itself must have a much higher power at the power actually required to open and close the door, knowing that the door is balanced.

Or, si cette puissance excessive n'est pas réellement un handicap si l'on envisage le point de vue économique de la porte basculante, elle est particulièrement peu souhaitable du point de vue de la sécurité. En effet, moins le moteur électrique est puissant, moins les manoeuvres d'ouverture et de fermeture de l'ouvrant sont dangereuses pour un éventuel usager se situant à proximité. Par ailleurs, la normalisation actuelle conduit à réduire au minimum cette puissance des moyens moteurs pour la commande d'ouverture automatique de porte basculante, puissance qui n'est plus compatible aux contraintes rencontrées dans le cadre du dispositif de commande électromécanique précisément décrit dans ce document EP-B-0.089.909.However, if this excessive power is not really a handicap if we consider the economic point of view of the overhead door, it is particularly undesirable from the point of view of safety. In fact, the less powerful the electric motor, the less dangerous the opening and closing operations of the opening are for a possible user located nearby. Furthermore, current standardization leads to reducing to a minimum this power of the motor means for the automatic opening control of the overhead door, a power which is no longer compatible with the constraints encountered in the context of the electromechanical control device precisely described in this document. EP-B-0.089.909.

Il convient de signaler, en outre, qu'en cas de commande de débrayage pour autoriser l'ouverture ou la fermeture manuelle de la porte basculante, ce débrayage intervient entre la partie moteur électrique et la partie réducteur de vitesse. Par conséquent, lors d'une ouverture manuelle de la porte basculante, le fait de maintenir la liaison entre les moyens de transmission, reliés à l'ouvrant, et ledit réducteur de vitesse oblige également, à entraîner ce dernier. Il en résulte que l'ouvrant basculant ne peut être manoeuvré que très lentement avec une impression de lourdeur de ce dernier.It should also be noted that in the event of a clutch release command to authorize the manual opening or closing of the door tilting, this disengagement occurs between the electric motor part and the speed reduction part. Consequently, during a manual opening of the tilting door, the fact of maintaining the connection between the transmission means, connected to the leaf, and said speed reducer also obliges, to drive the latter. As a result, the tilting opening can only be operated very slowly with an impression of heaviness of the latter.

La présente invention s'est donc proposée de remédier à l'ensemble des inconvénients précités et la solution qui a été retenue est, à la fois, simple, ce qui est synonyme de fiabilité, et sûre dans la mesure où le fonctionnement du dispositif de commande électromécanique perd son caractère aléatoire, tout en faisant intervenir un moteur électrique de moindre puissance.The present invention has therefore proposed to remedy all of the aforementioned drawbacks and the solution which has been adopted is both simple, which is synonymous with reliability, and safe insofar as the operation of the device electromechanical control loses its randomness, while involving a lower power electric motor.

En fait, l'invention telle qu'elle est caractérisée dans les revendications résout le problème et consiste en un dispositif de commande électromécanique pour porte basculante, notamment, pour porte basculante de garage, composé d'un ouvrant équilibré par des contre-poids latéraux reliés audit ouvrant par des câbles ou chaînes s'enroulant, partiellement, autour de poulies ou pignons dentés entraînés par l'intermédiaire de moyens de transmission coopérant avec des moyens d'entraînement d'un ensemble moto-réducteur, caractérisé par le fait qu'il comporte au moins un patin d'entraînement rapporté sur l'ouvrant et apte à coopérer, directement, avec les moyens d'entraînement de l'ensemble moto-réducteur en phase initiale, respectivement, finale, d'ouverture et de fermeture de la porte basculante, correspondant aux phases de verrouillage et de déverrouillage de l'ouvrant, ledit dispositif de commande électromécanique comportant, en outre, des moyens de débrayage actionnés au travers du ou des patins d'entraînement pour débrayer l'ensemble moto-réducteur desdits moyens de transmission durant cette phase initiale, respectivement, finale d'ouverture et de fermeture.In fact, the invention as characterized in the claims solves the problem and consists of an electromechanical control device for an up-and-over door, in particular for an up-and-over garage door, composed of an opening balanced by lateral counterweights. connected to said opening by cables or chains partially winding around toothed pulleys or pinions driven by means of transmission cooperating with means for driving a motor-reduction unit, characterized in that it comprises at least one drive shoe attached to the opening and able to cooperate, directly, with the drive means of the gear motor assembly in the initial, respectively, final, opening and closing phases of the tilting door, corresponding to the locking and unlocking phases of the opening, said electromechanical control device further comprising disengaging means e actuated through the drive shoe (s) to disengage the motor-reduction unit from said transmission means during this initial, respectively, final opening and closing phase.

Selon une autre caractéristique de cette invention, le dispositif de commande électromécanique comporte des moyens de verrouillage de l'ouvrant contre le dormant, lesdits moyens de verrouillage étant constitués par la coopération, en position de fermeture de la porte basculante, du ou des patins d'entraînement avec les moyens d'entraînement de l'ensemble moto-réducteur lequel comporte un frein mécanique actionné lorsque le moteur électrique n'est pas sollicité.According to another characteristic of this invention, the electromechanical control device comprises means for locking the opening against the frame, said locking means being formed by cooperation, in the closed position of the tilting door, of the pad or pads with the means drive of the gear motor assembly which includes a mechanical brake actuated when the electric motor is not stressed.

Selon une autre caractéristique de l'invention, ce dispositif de commande électromécanique comporte des moyens de commande de débrayage et de déverrouillage manuel agissant sur lesdits moyens de débrayage pour, d'une part, défaire la coopération entre les moyens de transmission et les moyens d'entraînement de l'ensemble moto-réducteur et, d'autre part, entre lesdits moyens d'entraînement de ce dernier et le ou les patins d'entraînement associés à l'ouvrant.According to another characteristic of the invention, this electromechanical control device comprises clutch release and manual unlocking means acting on said clutch release means, on the one hand, to undo the cooperation between the transmission means and the transmission means. drive of the gear motor assembly and, on the other hand, between said drive means of the latter and the drive shoe or pads associated with the opening.

Les principaux avantages obtenus grâce à cette invention consistent, essentiellement, en ce que le moteur électrique associé à l'ensemble moto-réducteur ne doit disposer que de la puissance nécessaire à la commande d'ouverture et de fermeture d'un ouvrant équilibré, puisqu'aucune fonction complémentaire ne lui est associée. En effet, ce dispositif de commande électromécanique est dépourvu de tout temporisateur mécanique, mais aussi de moyens de verrouillage spécifiques manoeuvrables individuellement, puisque ces moyens de verrouillage sont constitués, substantiellement, par la simple coopération des patins d'entraînement avec l'ensemble moto-réducteur au travers des moyens d'entraînement de ce dernier.The main advantages obtained thanks to this invention consist, essentially, in that the electric motor associated with the geared motor assembly must only have the power necessary to control the opening and closing of a balanced opening, since 'no additional function is associated with it. In fact, this electromechanical control device is devoid of any mechanical timer, but also of specific locking means which can be operated individually, since these locking means are constituted, essentially, by the simple cooperation of the drive pads with the motorized assembly. reducer through the latter's drive means.

Telle que représentée dans la figure 1, la présente invention est relative à un dispositif de commande électromécanique 1 pour porte basculante 2. Ainsi, ce dispositif est plus particulièrement applicable à une porte basculante de garage comprenant un dormant 3 composé de deux montants 4, 5, reliés, à leur partie supérieure, par un linteau 6 placé horizontalement. Cette porte basculante 2 est pourvue, en outre, d'un ouvrant basculant 7, celui-ci étant guidé, par l'intermédiaire de tétons de guidage ou similaires se déplaçant dans des rails verticaux aménagés précisément dans les montants 4, 5, du dormant 3. L'ouvrant 7 est, par ailleurs, équilibré au moyen de contrepoids 8, 9 coulissant dans des glissières verticales se situant, éventuellement à hauteur des montants 4, 5 du dormant 3.As shown in Figure 1, the present invention relates to an electromechanical control device 1 for overhead door 2. Thus, this device is more particularly applicable to a garage overhead door comprising a frame 3 composed of two uprights 4, 5 , connected at their upper part by a lintel 6 placed horizontally. This tilting door 2 is further provided with a tilting opening 7, the latter being guided, by means of guide pins or the like moving in vertical rails precisely arranged in the uprights 4, 5, of the frame. 3. The opening 7 is, moreover, balanced by means of counterweights 8, 9 sliding in vertical slides located, possibly at the height of the uprights 4, 5 of the frame 3.

Plus précisément, ces contrepoids sont reliés à l'ouvrant 7 par l'intermédiaire de câbles ou chaînes 10, 11 s'enroulant, partiellement, autour de poulies ou pignons dentés 12, 13. Ces derniers sont entraînés au moyen du dispositif de commande électromécanique 1.More precisely, these counterweights are connected to the opening 7 by means of cables or chains 10, 11 which are partially wound around pulleys or toothed pinions 12, 13. The latter are driven by means of the electromechanical control device 1.

Tel que représenté dans la figure 2, ce dispositif de commande électromécanique 1 consiste en un ensemble moto-réducteur électrique 14 rendu solidaire au moyen d'un support 15 de la face interne 16 du linteau 6 et comportant des moyens d'entraînement 17 coopérant avec des moyens de transmission 18 lesquels sont reliés aux poulies ou pignons dentés 12, 13 en vue de les entraîner en rotation.As shown in FIG. 2, this electromechanical control device 1 consists of an electric geared motor assembly 14 made integral by means of a support 15 of the internal face 16 of the lintel 6 and comprising drive means 17 cooperating with transmission means 18 which are connected to the pulleys or toothed pinions 12, 13 in order to drive them in rotation.

Il convient de préciser que le moteur électrique associé à l'ensemble moto-réducteur 14, est équipé d'un frein mécanique actionné dès la coupure de l'alimentation en énergie électrique dudit moteur.It should be noted that the electric motor associated with the geared motor assembly 14 is equipped with a mechanical brake actuated when the electric power supply to said motor is cut off.

En ce qui concerne, plus particulièrement, les moyens d'entraînement 17 équipant l'ensemble moto-réducteur 14, ceux-ci se présentent sous forme d'un tambour moteur 19 à axe de rotation horizontal et maintenu libre en rotation, au niveau de ses extrémités 20, 21 dans des paliers 22, 23 associés au support 15. En fait, ce tambour moteur 19 peut disposer dans sa partie interne et de manière connue pour l'Homme du Métier, d'un moteur électrique auquel est associé un réducteur. Toutefois, ce moteur électrique et ce réducteur sont également en mesure de prendre position extérieurement à ce tambour moteur 19 tout en assurant l'entraînement. Par ailleurs, ce dernier comporte, sur sa périphérie externe, un ou plusieurs éléments d'entraînement par friction 24, 24A, tels que des courroies en caoutchouc dont une, au moins, vient à coopérer avec lesdits moyens de transmission 18.As regards, more particularly, the drive means 17 equipping the geared motor assembly 14, these are in the form of a motor drum 19 with horizontal axis of rotation and kept free in rotation, at the level of its ends 20, 21 in bearings 22, 23 associated with the support 15. In fact, this drum motor 19 may have in its internal part and in a manner known to those skilled in the art, an electric motor with which a reduction gear is associated . However, this electric motor and this reducer are also able to take a position externally to this motor drum 19 while ensuring the drive. Furthermore, the latter comprises, on its outer periphery, one or more friction drive elements 24, 24A, such as rubber belts, one of which at least comes to cooperate with said transmission means 18.

Ces derniers se composent d'un arbre 25 parallèle au tambour moteur 19 et traversant, de part en part, des paliers 26, 27 disposés dans les mêmes plans verticaux que les paliers 22, 23. Tout comme ces derniers, ces paliers 26, 27 sont dépendant du support 15.The latter consist of a shaft 25 parallel to the motor drum 19 and passing right through from the bearings 26, 27 arranged in the same vertical planes as the bearings 22, 23. Just like the latter, these bearings 26, 27 are dependent on the support 15.

Par ailleurs, au-delà de ces paliers 26, 27, dans lesquels l'arbre 25 est, finalement, monté libre en rotation, celui-ci coopère, au travers de cardans 28, 29, avec des arbres d'entraînement 30, 31 reliés aux poulies ou pignons dentés 12, 13, en vue d'en assurer l'entraînement en rotation.Furthermore, beyond these bearings 26, 27, in which the shaft 25 is, finally, mounted to rotate freely, the latter cooperates, through cardan joints 28, 29, with drive shafts 30, 31 connected to the pulleys or toothed pinions 12, 13, in order to ensure the drive in rotation.

Il convient de remarquer, en outre, que sur l'arbre 25, se situant sous le tambour moteur 19, est monté solidaire ou en rotation au moins un rouleau mené 32 destiné à coopérer avec un élément d'entraînement par friction 24 notamment pour garantir l'ouverture et la fermeture de la porte basculante 2. Préférentiellement, tant le rouleau mené 32 que les éléments d'entraînement par friction 24, 24A sont constitués en un matériau relativement adhérent, par exemple en caoutchouc.It should be noted, moreover, that on the shaft 25, located under the motor drum 19, is mounted integral or in rotation at least one driven roller 32 intended to cooperate with a friction drive element 24 in particular to guarantee opening and closing of the tilting door 2. Preferably, both the driven roller 32 and the friction drive elements 24, 24A are made of a relatively adherent material, for example rubber.

Ainsi,en fonction du sens de rotation conféré au tambour moteur 19, l'on obtient, par l'intermédiaire desdits moyens de transmission 18, l'ouverture ou la fermeture de la porte basculante 2. Toutefois, se pose, plus particulièrement, le problème du verrouillage de l'ouvrant 7 une fois refermé sur le dormant 3.Thus, depending on the direction of rotation imparted to the motor drum 19, one obtains, by means of said transmission means 18, the opening or closing of the tilting door 2. However, arises, more particularly, the problem of locking the sash 7 once closed on the frame 3.

Aussi et selon l'invention, le dispositif de commande électromécanique 1 comporte au moins un patin d'entraînement 33, 33A rapporté en bordure supérieure 34 et du côté interne 35 dudit ouvrant 7 et apte à coopérer, directement, avec les moyens d'entraînement 17 de l'ensemble moto-réducteur 14, plus particulièrement, en phase initiale, respectivement, finale, d'ouverture et de fermeture de la porte basculante 2. En définitive, ces phases initiales, respectivement, finales d'ouverture et de fermeture correspondent aux phases de verrouillage et de déverrouillage de l'ouvrant 7.Also and according to the invention, the electromechanical control device 1 comprises at least one drive shoe 33, 33A attached at the upper edge 34 and on the internal side 35 of said opening 7 and able to cooperate, directly, with the drive means 17 of the geared motor assembly 14, more particularly, in the initial, respectively, final, opening and closing phase of the tilting door 2. Ultimately, these initial, respectively, final phases of opening and closing correspond during the locking and unlocking phases of the sash 7.

Cependant et de manière à permettre la coopération des patins d'entraînement 33, 33A avec lesdits moyens d'entraînement 17, le dispositif de commande électromécanique 1 est muni, en outre, de moyens de débrayage 36 actionnés au travers desdits patins d'entraînement 33, 33A, précisément, pour débrayer l'ensemble moto-réducteur 14 des moyens de transmission 18 durant cette phase initiale, respectivement, finale d'ouverture et de fermeture.However, and so as to allow the cooperation of the drive shoes 33, 33A with said drive means 17, the electromechanical control device 1 is further provided with declutching means 36 actuated through said drive shoes 33 , 33A, specifically, to disengage the motor-reducer assembly 14 of the transmission means 18 during this initial, respectively, final opening and closing phase.

Selon un mode de réalisation préférentiel, ces moyens de débrayage 36 consistent en des moyens de liaison élastiques 37 reliant les paliers 26, 27, correspondant à l'arbre 25, aux paliers 22, 23, supportant le tambour moteur 19, un seul jeu de palier 22, 23 ou 26, 27 étant monté de manière rigide sur la traverse 38 correspondant au support 15 et fixée sur la face interne 16 du linteau 6. En fait, il s'agit, au travers de cette mobilité relative entre les paliers 22, 23 du tambour moteur 19 et les paliers 26, 27 de l'arbre 25, d'autoriser le dégagement des moyens d'entraînement 17 par rapport aux moyens de transmission 18 en mettant sous contrainte des moyens élastiques susceptibles de ramener les éléments dans leur position d'engagement.According to a preferred embodiment, these declutching means 36 consist of elastic connection means 37 connecting the bearings 26, 27, corresponding to the shaft 25, to the bearings 22, 23, supporting the motor drum 19, a single set of bearing 22, 23 or 26, 27 being rigidly mounted on the crosspiece 38 corresponding to the support 15 and fixed on the internal face 16 of the lintel 6. In fact, it is, through this relative mobility between the bearings 22 , 23 of the drum motor 19 and the bearings 26, 27 of the shaft 25, of authorizing the disengagement of the drive means 17 relative to the transmission means 18 by stressing elastic means capable of bringing the elements back into their engagement position.

Dans le cadre du mode de réalisation illustré dans les dessins et plus particulièrement dans la figure 2, il a été retenu le cas où les paliers 22, 23, correspondant au tambour moteur 19, sont rendus solidaires de ladite travers 38, tandis que les paliers 26, 27, supportant l'arbre 25 sont rendus mobiles au travers des moyens de liaison élastiques 37 les reliant, précisément, auxdits paliers 22, 23. A noter que cette mobilité a lieu, notamment, dans le sens vertical de sorte qu'en cas d'intervention des patins d'entraînement 33, 33A ou de moyens de commande manuels 39, ledit arbre 25 soit en mesure de s'écarter du tambour moteur 19 afin que son rouleau mené 32 ne vienne plus à adhérer à l'élément d'entraînement par friction 24 correspondant.In the context of the embodiment illustrated in the drawings and more particularly in FIG. 2, the case has been retained where the bearings 22, 23, corresponding to the motor drum 19, are made integral with said cross member 38, while the bearings 26, 27, supporting the shaft 25 are made mobile through elastic connection means 37 connecting them, precisely, to said bearings 22, 23. Note that this mobility takes place, in particular, in the vertical direction so that in case of intervention of the driving pads 33, 33A or of manual control means 39, said shaft 25 is able to move away from the motor drum 19 so that its driven roller 32 no longer comes to adhere to the corresponding friction drive element 24.

A ce propos, il convient de remarquer que sur l'arbre 25 sont, en outre, montés, libres en rotation, des rouleaux 40, 40A au diamètre extérieur 41 à peine inférieur au diamètre 42 du ou des rouleaux menés 32. Ces rouleaux 40, 41 sont disposés en correspondance avec les éléments d'entraînement par friction 24, 24A du tambour moteur 19.In this regard, it should be noted that on the shaft 25 are further mounted, free to rotate, rollers 40, 40A with the outside diameter 41 just slightly less than the diameter 42 of the driven roller (s) 32. These rollers 40 , 41 are arranged in correspondence with the friction drive elements 24, 24A of the motor drum 19.

Ainsi, au moment de refermer la porte basculante 2 (voir figures 4A, 4B ; 5A, 5B) la ou les patins d'entraînement 33, 33A, se présentant sous forme d'une lame 43 disposée sensiblement perpendiculairement au plan de l'ouvrant 7 et orientée en direction du dormant 3, viennent à s'insérer entre lesdits éléments d'entraînement par friction 24, 24A et les rouleaux 40, 40A. Il en résulte par l'intermédiaire des moyens de débrayage 36 et notamment des moyens de liaison élastiques 37, l'écartement de l'arbre 25 par rapport au tambour moteur 19 sur une distance 44, de ladite lame 33. En fait, cet écartement suffit à empêcher l'adhérence du ou des éléments d'entraînement par friction 24 sur le ou les rouleaux menés 32. Il en découle l'arrêt de l'entraînement des moyens de transmission 18 tandis que l'ensemble moto-réducteur 14 continue à fonctionner de sorte qu'au travers de la coopération des éléments d'entraînement par friction 24, 24A sur lesdits patins d'entraînement 33, 33A, l'on obtienne un entraînement direct de l'ouvrant 7 jusqu'à la venue en applique de ce dernier contre le dormant 3. Un capteur équipant, avantageusement, le dispositif de commande électromécanique 1 permet de détecter cette position de fermeture de la porte basculante 2.Thus, at the time of closing the tilting door 2 (see FIGS. 4A, 4B; 5A, 5B) the drive shoe or pads 33, 33A, being in the form of a blade 43 arranged substantially perpendicular to the plane of the opening 7 and oriented in the direction of the frame 3, are inserted between said friction drive elements 24, 24A and the rollers 40, 40A. This results by means of declutching means 36 and in particular elastic connection means 37, the spacing of the shaft 25 relative to the motor drum 19 over a distance 44, from said blade 33. In fact, this spacing suffices to prevent the adhesion of the friction drive element or elements 24 to the driven roller (s) 32. This results in the stopping of the drive of the transmission means 18 while the motor-reducer assembly 14 continues to operate so that through the cooperation of the friction drive elements 24, 24A on said drive pads 33, 33A, there is obtained a direct drive of the leaf 7 until the applied surface of the latter against the frame 3. A sensor equipping, advantageously, the electromechanical control device 1 makes it possible to detect this closed position of the tilting door 2.

A ce propos, il convient d'observer que dans cette position de fermeture, d'une part, le maintien de la coopération des patins d'entraînement 33, 33A avec les éléments d'entraînement par friction 24, 24A, notamment au travers de la poussée exercée par les rouleaux 40, 40A et, d'autre part, l'emploi d'un moteur muni d'un frein mécanique, confère à cette association d'éléments la structure de moyens de verrouillage. En effet, le déverrouillage ne peut être obtenu, dans ces conditions, qu'en actionnant l'ensemble moto-réducteur 14 ou qu'en intervenant sur les moyens de commande manuels 39 aptes à actionner les moyens de débrayage 36 pour écarter davantage l'arbre 25 du tambour moteur 19 et, finalement, supprimer ou réduire l'adhérence des patins d'entraînement 33, 33A sur les éléments d'entraînement par friction 24, 24A sous l'action de la pression des rouleaux 40, 40A.In this regard, it should be observed that in this closed position, on the one hand, the maintenance of the cooperation of the drive shoes 33, 33A with the friction drive elements 24, 24A, in particular through the thrust exerted by the rollers 40, 40A and, on the other hand, the use of a motor fitted with a mechanical brake, gives this combination of elements the structure of locking means. In fact, unlocking can only be obtained under these conditions by actuating the geared motor assembly 14 or by intervening on the manual control means 39 capable of actuating the means of declutching 36 to further separate the shaft 25 from the motor drum 19 and, ultimately, to eliminate or reduce the adhesion of the drive shoes 33, 33A to the friction drive elements 24, 24A under the action of the pressure of the rollers 40, 40A.

Selon un mode de réalisation préférentiel, les moyens de commande manuels 39 des moyens de débrayage 36 consistent en un excentrique 45 disposé entre les paliers 22, 23 et 26, 27 et dont la rotation, assurée au travers d'une tige de commande 46 et d'un levier de manoeuvre 47, provoque, précisément, l'écartement du palier 22 par rapport au palier 26, respectivement, du palier 23 par rapport au palier 27. En ce qui concerne les moyens de liaison élastiques 37 ceux-ci sont constitués, principalement, par au moins un ressort 48 précontraint en vue de maintenir rapprochés les paliers 22, 23 des paliers 26, 27. Toutefois, des moyens de guidage appropriés 49 peuvent encore compléter ces moyens de liaison élastiques 37 afin de contrôler dans leur déplacement, les paliers 26, 27 ou, selon le cas les paliers 22, 23. Par ailleurs et selon un autre mode de réalisation, ces moyens de guidage 49 peuvent être remplacés par des moyens d'articulation reliant le jeu de palier mobile soit à la traverse 38, soit au jeu de palier fixe. En fait, là encore, de tels moyens d'articulation ont pour fonction de guider lesdits paliers mobiles dans leur déplacement.According to a preferred embodiment, the manual control means 39 of the declutching means 36 consist of an eccentric 45 disposed between the bearings 22, 23 and 26, 27 and the rotation of which is ensured through a control rod 46 and of an operating lever 47, causes, precisely, the spacing of the bearing 22 relative to the bearing 26, respectively, of the bearing 23 relative to the bearing 27. As regards the elastic connection means 37 these consist , mainly, by at least one spring 48 prestressed in order to keep the bearings 22, 23 close to the bearings 26, 27. However, suitable guide means 49 can also supplement these elastic connection means 37 in order to control their movement, the bearings 26, 27 or, as the case may be the bearings 22, 23. Furthermore and according to another embodiment, these guide means 49 can be replaced by articulation means connecting the set of mobile bearings either at the cross-member 38, or at the set of fixed bearings. In fact, here again, such articulation means have the function of guiding said movable bearings in their movement.

L'on observera que la présente invention a pour avantage qu'en cas de débrayage manuel, l'ensemble moto-réducteur 14 est totalement désolidarisé des moyens de transmission 18. Il en résulte une commande d'ouverture et de fermeture manuelle de la porte basculante 2 considérablement facilitée.It will be observed that the present invention has the advantage that in the event of manual declutching, the geared motor assembly 14 is completely disconnected from the transmission means 18. This results in a manual opening and closing control of the door tilting 2 considerably facilitated.

L'on se reporte, plus particulièrement, à la figure 6.We refer, more particularly, to FIG. 6.

En définitive, il convient d'observer que plus la lame 43 des patins d'entraînement 33, 33A est longue, c'est-à-dire s'étend en avant de l'ouvrant 7, plutôt l'on obtiendra un entraînement direct de cet ouvrant 7 par l'intermédiaire de l'ensemble moto-réducteur 14 et moins le fonctionnement du dispositif de commande électromécanique sera dépendant d'obstacles que peut rencontrer l'ouvrant 7 en phase finale de fermeture. Toutefois, en prolongeant, d'avantage cette lame 43, il est nécessaire de prévoir dans le linteau 6, correspondant au dormant 3, et, peut être, dans le linteau 50 dans la maçonnerie, une ouverture dans laquelle peut s'engager l'extrémité avant 51 de ladite lame 43 en position de fermeture et de verrouillage de l'ouvrant 7. A noter que cette extrémité avant 51 peut être légèrement effilée de manière à limiter l'entaillage des linteaux 6 et 50.Ultimately, it should be observed that the longer the blade 43 of the drive shoes 33, 33A, that is to say extends in front of the opening 7, rather a direct drive will be obtained of this opening 7 via the motor-reducer assembly 14 and less the operation of the electromechanical control device will be dependent on obstacles that the opening 7 may encounter in the final closing phase. However, by extending this blade 43 more, it is necessary to provide in the lintel 6, corresponding to the frame 3, and, may be, in the lintel 50 in the masonry, an opening in which can engage the front end 51 of said blade 43 in the closed and locked position of the opening 7. Note that this front end 51 can be slightly tapered so as to limit the notching of the lintels 6 and 50.

En outre, il doit être envisagé la situation particulière où, en raison d'un plafond bas, le chant supérieur du linteau 6, correspondant au dormant 3, ne respecte qu'une faible distance par rapport au plafond 52. Dans de telles conditions, une lame de grande longueur 43 associée au patin d'entraînement 33, 33A, peut créer une gêne et, plus particulièrement, à la fermeture de la porte basculante 2. Notamment, l'extrémité avant 51 de cette lame 43 peut buter contre ce plafond 52 et peut empêcher l'ouverture et/ou la fermeture de l'ouvrant 7. Dans une telle situation, ladite lame 43 peut être prévue pivotante autour d'un axe de rotation horizontal, à hauteur de son extrémité arrière 53 de sorte qu'en cours d'ouverture de la porte basculante 2, elle soit en mesure de se rabattre en direction de l'ouvrant 7 sous l'action d'une came 54 disposée au plafond 52 de la construction. En définitive, cette came 54 permet d'éviter que l'extrémité avant 51 de la lame 43 correspondant aux patins d'entraînement 33, 33A ne forme butée en venant à coopérer avec le plafond 52 et ne s'oppose, plus particulièrement, à la fermeture de l'ouvrant 7. Une telle lame 43 est encore soumise à des moyens de rappel élastiques lui permettant de retrouver sa position initiale après avoir quitté la came 54.In addition, the particular situation should be considered where, due to a low ceiling, the upper edge of the lintel 6, corresponding to the frame 3, respects only a small distance from the ceiling 52. Under such conditions, a very long blade 43 associated with the drive shoe 33, 33A, can create discomfort and, more particularly, when the tilting door 2 is closed. In particular, the front end 51 of this blade 43 can abut against this ceiling 52 and can prevent the opening and / or closing of the opening 7. In such a situation, said blade 43 can be provided pivoting about a horizontal axis of rotation, at the level of its rear end 53 so that during the opening of the tilting door 2, it is able to fold in the direction of the opening 7 under the action of a cam 54 disposed on the ceiling 52 of the construction. Ultimately, this cam 54 makes it possible to prevent the front end 51 of the blade 43 corresponding to the drive shoes 33, 33A from forming a stop coming to cooperate with the ceiling 52 and not, more particularly, opposing closing the opening 7. Such a blade 43 is still subjected to elastic return means enabling it to return to its initial position after leaving the cam 54.

Ainsi, la présente invention permet, malgré une grande simplicité, de répondre à l'ensemble des problèmes rencontrés, par le passé au travers des dispositifs de commande électromécanique connue. Cette simplicité est, bien sûr, gage de fiabilité ce qui n'est pas une qualité vaine dans le cadre des portes basculantes 2 où intervient la notion de sécurité à l'effraction.Thus, the present invention allows, despite great simplicity, to meet all of the problems encountered in the past through known electromechanical control devices. This simplicity is, of course, a guarantee of reliability, which is not a vain quality in the context of up-and-over doors 2 where the concept of security against break-in intervenes.
