Definitions

  • the invention relates to a tilting door device with assisted tilting. More particularly, the invention relates to a closing and opening device of a construction comprising a garage door type door for tilting from a vertical position to a horizontal position to obstruct or not a passage.
  • the tilting of the door is generally obtained by sliding along a guide device generally in the form of lateral guide rails which are mounted on a door jamb.
  • This switch has its origin in the ad hoc application of a tilting force by a user, for example by pulling on a handle provided on said door. This force can also come from a motor controlled by the user.
  • a traction system connected to the door to counterbalance the weight of the door, for example a counterweight or a system of springs.
  • the traction system is connected to the door via a connecting element. This traction system exerts, via the connecting element, a vertical traction force on the door partially compensating for the weight of the door.
  • the connecting element for example in the form of a cable, connects the counterweight to an anchoring device provided on the lower part of the door.
  • the pulling force resulting from this traction device is vertical and does not determine the orientation in which the door will swing.
  • the pulling force can cause the door to swing in one direction or the other, that is to say inwardly along the ceiling of the garage or outside the garage .
  • guiding elements generally pulleys mounted on the same face and on each side of said face of a door, cooperating with rails guidance.
  • These guide rails are integrated in the door frame for example vertically on either side of the door and horizontally along the ceiling of the garage.
  • these pulleys also serve as means for anchoring the connecting element, said connecting element being fixedly mounted on said pulleys for example in the center of the lower pulleys.
  • an engine can be installed in the device.
  • Such an engine can provide a force capable of completing or replacing the help provided by a traction system to tilt a door.
  • An engine can also be a means of fully automating the tilting of the door avoiding a user having to provide the initial pulling force to tilt the door.
  • the guide rails having a curved area are complex in construction and installation. In addition, they do not help to avoid a significant effort required by the user to initially move the door from its vertical position to a horizontal position.
  • the invention therefore aims to provide a closure device whose opening / closing tilting system is simple to implement and installation, the device according to the invention requiring only few additional parts and being compact while allowing to guide the tilting the door without requiring the application of excessive pulling force.
  • the closure device comprises a door having two opposite general faces, said front face and rear face, a so-called upper side, an opposite side said lower and opposite lateral sides connecting the upper and lower sides, at least two guiding systems comprising a first guide element which is arranged in line with the door, each associated respectively with the two opposite lateral sides of the door and near the upper side of said door.
  • each guide system comprises a second guide element remote from the first guide element and arranged on the side and offset from the rear face of the door in the vertical position thereof.

  • the guide elements are of the known type and such as rollers or guide pulleys. They are intended to cooperate with a guiding device such as guide rails located on either side of an opening to be closed by the garage door. To ensure the positioning of the door from the vertical to the horizontal parallel to the ceiling, two sides are therefore provided with vertical rails and horizontal rails.
  • the guide elements of each guide system when applying a vertical pulling force upwards on the door, abut against the upper part of the horizontal guide rails.
  • the presence and offset positioning of the secondary guide member provides the offset of the stop of the guide system against the upper portion of the guide rail relative to the axis of application of the pulling force.
  • This offset generates a bearing axis of the door inclined relative to the axis of application of the tensile force, such an axis passing on the one hand by the anchor point of the connecting element and on the other hand, by the stop point of the guidance system.
  • This inclination of the support axis with respect to the axis of application of the pulling force of the door makes it possible to ensure the tilting of the door according to the chosen orientation.
  • the first and second guide elements of each guide system are mounted on a common spacer so that they can both cooperate with the same horizontal guide rail.
  • This spacer is itself rotated on the door, in particular near a lateral upper side of said door, to allow a change in positioning of the guide elements relative to the plane of the door during the tilting.
  • the secondary guide element is mounted on the spacer in a position ensuring the desired support axis when the door is in the vertical position, typically closed, and that during the opening swing of the

  • Such positioning allows to limit the size of the door above the guide rails when in the open position.
  • the spacer comprises a movable part such as a hub cooperating with an interface piece integral with the rear face of the door and having at least one complementary orifice of said hub.

  • the guide elements are mounted in a fixed position on the spacer.
  • a rotation thereof changes the relative positioning of the guide elements relative to fixed elements of the doorframe, for example the guide rails.
  • the means for limiting the spacer imposes on said spacer a fixed position such that a horizontal plane tangential to the upper end of the secondary guide element is above a plane horizontal tangent to an upper end of the first guide member of the same pair.

  • the first element is positioned in this position without contact with said upper internal part of this guide rail.
  • the initial stop of the guiding system which determines the bearing axis of the door as defined above, is therefore directly and solely between the second element of guide and the inner upper part of the horizontal guide rail.
  • This stop only performed on the second guide member provides a bearing axis having an inclination relative to the axis of traction greater than if the two guide elements simultaneously abut against the inner upper portion of the guide rail. This greater inclination of the support axis ensures better tilting of the door opening.

Dans la suite de la description les termes « bas », « haut », « inférieur » «supérieur », « arrière », « avant » sont utilisés dans le cadre d'une installation normale du dispositif, c'est-à-dire relatif à une notion verticale par rapport à un sol plat horizontal.In the remainder of the description, the terms "down", "up", "lower", "upper", "back", "forward" are used as part of a normal installation of the device, that is to say relative to a vertical concept compared to a flat horizontal ground.

Il est connu dans l'état de la technique des portes basculantes qui obstruent un passage en position verticale et basculent dans une position horizontale afin de libérer ledit passage. Ces portes sont par exemple destinées aux garages, individuels ou collectifs, et peuvent être automatisées afin de laisser passer les voitures sans obliger le conducteur à descendre du véhicule pour ouvrir puis refermer la porte. En position ouverte et horizontale, la porte est généralement parallèle à un plafond le long duquel elle bascule pour libérer le passage.It is known in the state of the art tilting doors that obstruct a passage in vertical position and tilt in a horizontal position to release said passage. These doors are for example for garages, individual or collective, and can be automated to let the cars without requiring the driver to get off the vehicle to open and close the door. In the open and horizontal position, the door is generally parallel to a ceiling along which it tilts to free the passage.

Le basculement de la porte est généralement obtenu par son coulissement le long d'un dispositif de guidage se présentant généralement sous la forme de rails de guidage latéraux qui sont montés sur un chambranle de porte. Ce basculement trouve son origine dans l'application ad hoc d'une force de basculement par un utilisateur, par exemple en tirant sur une poignée prévue sur ladite porte. Cette force peut aussi provenir d'un moteur commandé par l'utilisateur.The tilting of the door is generally obtained by sliding along a guide device generally in the form of lateral guide rails which are mounted on a door jamb. This switch has its origin in the ad hoc application of a tilting force by a user, for example by pulling on a handle provided on said door. This force can also come from a motor controlled by the user.

Pour faciliter le basculement et afin que la porte reste horizontale malgré le poids de la porte, en particulier lorsque la force initiale de basculement est directement produite par un utilisateur, on utilise de manière connue un système de traction relié à la porte permettant de contre balancer le poids de la porte, par exemple un contrepoids ou encore un système de ressorts. Le système de traction est relié à la porte via un élément de liaison. Ce système de traction exerce, via l'élément de liaison, une force de traction verticale sur la porte compensant en partie le poids de la porte.To facilitate the tilting and so that the door remains horizontal despite the weight of the door, particularly when the initial tilting force is directly produced by a user, it is used in a known manner a traction system connected to the door to counterbalance the weight of the door, for example a counterweight or a system of springs. The traction system is connected to the door via a connecting element. This traction system exerts, via the connecting element, a vertical traction force on the door partially compensating for the weight of the door.

Cette compensation du poids de la porte facilite le basculement de la porte par un utilisateur. Dans le cas d'un contrepoids, l'élément de liaison, par exemple sous forme de câble, relie le contrepoids à un dispositif d'ancrage prévu sur la partie basse de la porte.This weight compensation of the door facilitates the tilting of the door by a user. In the case of a counterweight, the connecting element, for example in the form of a cable, connects the counterweight to an anchoring device provided on the lower part of the door.

Cependant, la force de traction résultant de ce dispositif de traction est verticale et ne permet pas de déterminer l'orientation dans laquelle la porte va basculer. Ainsi, sans dispositif de guidage particulier, la force de traction peut amener la porte à basculer dans un sens ou dans l'autre c'est-à-dire vers l'intérieur le long du plafond du garage ou vers l'extérieur du garage.However, the pulling force resulting from this traction device is vertical and does not determine the orientation in which the door will swing. Thus, without particular guiding device, the pulling force can cause the door to swing in one direction or the other, that is to say inwardly along the ceiling of the garage or outside the garage .

Afin d'éviter cela, il est connu de guider le basculement de la porte à l'aide d'éléments de guidage, généralement des poulies montés sur une même face et de chaque coté de ladite face d'une porte, coopérant avec des rails de guidage. Ces rails de guidages sont intégrés au chambranle par exemple verticalement de part et d'autre de la porte et horizontalement le long du plafond du garage. Généralement, ces poulies servent aussi de moyen d'ancrage de l'élément de liaison, ledit élément de liaison étant monté fixe sur lesdites poulies par exemple au centre des poulies inférieures.In order to avoid this, it is known to guide the tilting of the door by means of guiding elements, generally pulleys mounted on the same face and on each side of said face of a door, cooperating with rails guidance. These guide rails are integrated in the door frame for example vertically on either side of the door and horizontally along the ceiling of the garage. Generally, these pulleys also serve as means for anchoring the connecting element, said connecting element being fixedly mounted on said pulleys for example in the center of the lower pulleys.

Pour guider le basculement de la porte de sa position verticale à sa position horizontale, il est connu par exemple d'utiliser des rails de guidage ayant une zone courbée. De tels rails coopèrent avec les poulies et imposent auxdites poulies un chemin présentant une partie courbe assurant ainsi un basculement de la porte selon l'orientation définie par les rails. Eventuellement, afin de faciliter ou fournir l'effort initial permettant de faire basculer la porte, un moteur peut être installé dans le dispositif. Un tel moteur peut fournir une force apte à compléter ou remplacer l'aide fournie par un système de traction pour faire basculer une porte. Un moteur peut aussi représenter un moyen d'automatisation complet du basculement de la porte évitant à un utilisateur d'avoir à fournir la force de traction initiale permettant de faire basculer la porte.To guide the tilting of the door from its vertical position to its horizontal position, it is known for example to use guide rails having a curved area. Such rails cooperate with the pulleys and impose on said pulleys a path having a curved portion thus ensuring a tilting of the door according to the orientation defined by the rails. Optionally, to facilitate or provide the initial effort to tilt the door, an engine can be installed in the device. Such an engine can provide a force capable of completing or replacing the help provided by a traction system to tilt a door. An engine can also be a means of fully automating the tilting of the door avoiding a user having to provide the initial pulling force to tilt the door.

Cependant, les rails de guidage comportant une zone courbe sont complexes de réalisation et d'installation. De plus, ils n'aident pas à éviter un effort important nécessaire à l'utilisateur pour déplacer initialement la porte de sa position verticale à une position horizontale.However, the guide rails having a curved area are complex in construction and installation. In addition, they do not help to avoid a significant effort required by the user to initially move the door from its vertical position to a horizontal position.

Il est possible d'assurer le basculement de la porte selon le sens désiré en la motorisant. Toutefois, une telle solution est complexe et ajoute un dispositif coûteux, encombrant et lourd aussi bien en installation qu'en entretien. Le guidage par rails à partie courbe et la motorisation peuvent être associés mais ne permettent pas pour autant de résoudre les problèmes précités.It is possible to tilt the door in the desired direction by motorizing it. However, such a solution is complex and adds an expensive, bulky and heavy device both in installation and maintenance. The curved rail guide and the motorization can be associated but do not allow to solve the aforementioned problems.

Le brevet US2008000 décrit un dispositif de fermeture selon le préambule de la revendication 1.The patent US2008000 discloses a closure device according to the preamble of claim 1.

L'invention a donc pour but de fournir un dispositif de fermeture dont le système de basculement ouverture/fermeture soit simple de réalisation et d'installation, le dispositif selon l'invention ne nécessitant que peu de pièces additionnelles et étant peu encombrant tout en permettant d'orienter le basculement de la porte sans nécessiter l'application d'une force de traction excessive.The invention therefore aims to provide a closure device whose opening / closing tilting system is simple to implement and installation, the device according to the invention requiring only few additional parts and being compact while allowing to guide the tilting the door without requiring the application of excessive pulling force.

Selon l'invention, le dispositif de fermeture comporte une porte présentant deux faces générales opposées, dites face avant et face arrière, un côté dit supérieur, un côté opposé dit inférieur et des côtés latéraux opposés reliant les côtés supérieur et inférieur, au moins deux systèmes de guidage comportant un premier élément de guidage qui est disposé au droit de la porte, associés chacun respectivement aux deux côtés opposés latéraux de la porte et à proximité du côté supérieur de ladite porte.According to the invention, the closure device comprises a door having two opposite general faces, said front face and rear face, a so-called upper side, an opposite side said lower and opposite lateral sides connecting the upper and lower sides, at least two guiding systems comprising a first guide element which is arranged in line with the door, each associated respectively with the two opposite lateral sides of the door and near the upper side of said door.

Le dispositif selon l'invention est caractérisé en ce que chaque système de guidage comporte un second élément de guidage distant du premier élément de guidage et agencé du coté et de manière décalée par rapport à la face arrière de la porte en position verticale de celle ci, le premier et second élément de guidage d'un même système de guidage de la porte formant une paire d'éléments de guidage. Chaque système de guidage comporte en outre une entretoise associée à la porte et mobile en rotation par rapport à ladite porte, l'entretoise étant d'une part montée mobile en rotation autour d'un axe parallèle à la face arrière de la porte et en dessous des éléments de guidage et d'autre part fixée auxdits premier et second éléments de guidage.The device according to the invention is characterized in that each guide system comprises a second guide element remote from the first guide element and arranged on the side and offset from the rear face of the door in the vertical position thereof. , the first and second guide members of the same door guide system forming a pair of guide elements. Each guiding system further comprises a spacer associated with the door and movable in rotation with respect to said door, the spacer being on the one hand rotatably mounted around an axis parallel to the rear face of the door and below the guide elements and secondly fixed to said first and second guide elements.

Les éléments de guidage sont du type connu et tels que des galets ou poulies de guidage. Ils sont destinés à coopérer avec un dispositif de guidage tel que des rails de guidages situés de part et d'autre d'une ouverture destinée à être fermée par la porte de garage. Pour assurer le positionnement de la porte de la verticale à l'horizontal parallèlement au plafond, de deux côtés sont donc prévus des rails verticaux et des rails horizontaux.The guide elements are of the known type and such as rollers or guide pulleys. They are intended to cooperate with a guiding device such as guide rails located on either side of an opening to be closed by the garage door. To ensure the positioning of the door from the vertical to the horizontal parallel to the ceiling, two sides are therefore provided with vertical rails and horizontal rails.

Lors d'un basculement de la porte en ouverture, le guidage en basculement de la porte se fait par coopération des rails horizontaux avec respectivement la paire d'éléments de guidage de chaque système de guidage.When the door is tilted open, the tilting of the door is made by cooperation of the horizontal rails with respectively the pair of guide elements of each guide system.

Selon l'invention, lors de l'application d'une force de traction verticale vers le haut sur la porte, les éléments de guidage de chaque système de guidage butent contre la partie supérieure des rails de guidage horizontaux. La présence et le positionnement en décalage de l'élément de guidage secondaire procurent le décalage de la butée du système de guidage contre la partie supérieure du rail de guidage par rapport à l'axe d'application de la force de traction. Ce décalage génère un axe d'appui de la porte incliné par rapport à l'axe d'application de la force de traction, un tel axe passant d'une part par le point d'ancrage de l'élément de liaison et d'autre part par le point de butée du système de guidage. Cette inclinaison de l'axe d'appui par rapport à l'axe d'application de la force de traction de la porte permet d'assurer le basculement de la porte selon l'orientation choisie.According to the invention, when applying a vertical pulling force upwards on the door, the guide elements of each guide system abut against the upper part of the horizontal guide rails. The presence and offset positioning of the secondary guide member provides the offset of the stop of the guide system against the upper portion of the guide rail relative to the axis of application of the pulling force. This offset generates a bearing axis of the door inclined relative to the axis of application of the tensile force, such an axis passing on the one hand by the anchor point of the connecting element and on the other hand, by the stop point of the guidance system. This inclination of the support axis with respect to the axis of application of the pulling force of the door makes it possible to ensure the tilting of the door according to the chosen orientation.

Les premiers et seconds éléments de guidage de chaque système de guidage sont montés sur une entretoise commune afin qu'ils puissent tous deux coopérer avec un même rail de guidage horizontal. Cette entretoise est elle-même montée en rotation sur la porte, en particulier à proximité d'un côté supérieur latéral de ladite porte, afin de permettre un changement de positionnement des éléments de guidage par rapport au plan de la porte durant le basculement. Il est ainsi possible que l'élément de guidage secondaire soit monté sur l'entretoise dans une position assurant l'axe d'appui désiré lorsque la porte est en position verticale, typiquement fermée, et qu'au cours du basculement en ouverture de la porte la rotation de l'entretoise par rapport à la porte amène ledit élément de guidage secondaire dans une autre disposition par rapport à la porte, par exemple dans un plan horizontal lorsque cette dernière est en position ouverte. Un tel positionnement permet de limiter l'encombrement de la porte au dessus des rails de guidage lorsqu'elle est en position ouverte.The first and second guide elements of each guide system are mounted on a common spacer so that they can both cooperate with the same horizontal guide rail. This spacer is itself rotated on the door, in particular near a lateral upper side of said door, to allow a change in positioning of the guide elements relative to the plane of the door during the tilting. It is thus possible that the secondary guide element is mounted on the spacer in a position ensuring the desired support axis when the door is in the vertical position, typically closed, and that during the opening swing of the The rotation of the spacer relative to the door causes said secondary guide element to be arranged in another arrangement with respect to the door, for example in a horizontal plane when the latter is in the open position. Such positioning allows to limit the size of the door above the guide rails when in the open position.

Afin d'être montée en rotation sur la porte, l'entretoise comporte une partie mobile tel qu'un moyeu coopérant avec une pièce d'interface solidaire de la face arrière de la porte et présentant au moins un orifice complémentaire dudit moyeu.In order to be mounted in rotation on the door, the spacer comprises a movable part such as a hub cooperating with an interface piece integral with the rear face of the door and having at least one complementary orifice of said hub.

Avantageusement, un système de guidage comporte un moyen de limitation de la rotation de l'entretoise par rapport à la porte. Ce moyen de limitation de la rotation de l'entretoise coopère par exemple en butée avec la porte, en position verticale de la porte.Advantageously, a guidance system comprises means for limiting the rotation of the spacer relative to the door. This means for limiting the rotation of the spacer cooperates for example in abutment with the door, in the vertical position of the door.

De préférence, le moyen de limitation de la rotation de l'entretoise constitue également un moyen d'agencement des premiers et seconds éléments de guidage entre eux.Preferably, the means for limiting the rotation of the spacer also constitutes a means for arranging the first and second guide elements together.

Les éléments de guidage sont montés en position fixe sur l'entretoise. Une rotation de celle-ci change donc le positionnement relatif des éléments de guidage par rapport aux éléments fixes du chambranle comme par exemple les rails de guidage. Ainsi, En position verticale de la porte, le moyen de limitation de l'entretoise impose à ladite entretoise une position fixe telle qu'un plan horizontal tangent à l'extrémité supérieure de l'élément de guidage secondaire est au dessus d'un plan horizontal tangent à une extrémité supérieure du premier élément de guidage d'une même paire. Ainsi, lors d'un basculement en ouverture de la porte depuis sa position fermée, c'est-à-dire verticale, le second élément de guidage est dans une position initiale telle que sa partie supérieure est en contact direct avec la partie interne supérieure du rail de guidage horizontal dans lequel ledit élément de guidage est inséré. Le premier élément est positionné dans cette position sans contact avec ladite partie interne supérieure de ce rail de guidage.The guide elements are mounted in a fixed position on the spacer. A rotation thereof changes the relative positioning of the guide elements relative to fixed elements of the doorframe, for example the guide rails. Thus, in the vertical position of the door, the means for limiting the spacer imposes on said spacer a fixed position such that a horizontal plane tangential to the upper end of the secondary guide element is above a plane horizontal tangent to an upper end of the first guide member of the same pair. Thus, during a tilting opening of the door from its closed position, that is to say vertical, the second guide element is in an initial position such that its upper portion is in direct contact with the upper internal part horizontal guide rail in which said guide member is inserted. The first element is positioned in this position without contact with said upper internal part of this guide rail.

Lors de l'application de la force de traction en ouverture, la butée initiale du système de guidage, qui détermine l'axe d'appui de la porte tel que défini ci-dessus, se fait donc directement et uniquement entre le second élément de guidage et la partie supérieure interne du rail de guidage horizontal. Cette butée uniquement réalisée sur le second élément de guidage assure un axe d'appui ayant une inclinaison par rapport à l'axe de traction plus importante que si les deux éléments de guidage butaient simultanément contre la partie supérieure interne du rail de guidage. Cette inclinaison plus importante de l'axe d'appui assure un meilleur basculement de la porte en ouverture.When applying the pulling force in opening, the initial stop of the guiding system, which determines the bearing axis of the door as defined above, is therefore directly and solely between the second element of guide and the inner upper part of the horizontal guide rail. This stop only performed on the second guide member provides a bearing axis having an inclination relative to the axis of traction greater than if the two guide elements simultaneously abut against the inner upper portion of the guide rail. This greater inclination of the support axis ensures better tilting of the door opening.

Le positionnement des éléments de guidage d'un système de guidage est en outre tel qu'en position verticale de la porte, un plan horizontal tangent horizontal à une extrémité inférieure de l'élément de guidage secondaire est au dessus d'un plan horizontal tangent à l'extrémité inférieure du premier élément de guidage d'une même paire.The positioning of the guiding elements of a guiding system is further such that, in the vertical position of the door, a horizontal horizontal tangent plane at a lower end of the secondary guiding element is above a tangent horizontal plane. at the lower end of the first guide member of the same pair.

Typiquement, en position verticale et fermée de la porte, seule le premier élément de guidage est en contact avec la partie inférieure interne du rail de guidage. Ce contact permet au système de guidage de porter l'ensemble du poids de la porte sur le premier élément de guidage. Un axe de support de la porte, défini par le point de contact entre le premier élément de guidage et la partie interne inférieure du rail de guidage horizontal d'une part et le centre de gravité de la porte d'autre part est ainsi sensiblement vertical. Cet axe de support permet d'éviter le basculement de la porte ou l'application d'efforts importants sur les rails de guidage verticaux.Typically, in the vertical and closed position of the door, only the first guide element is in contact with the inner lower portion of the guide rail. This contact allows the guide system to carry the entire weight of the door on the first guide element. A support axis of the door defined by the point of contact between the first guide element and the lower internal part of the horizontal guide rail on the one hand and the center of gravity of the door on the other hand is thus substantially vertical. . This support axis makes it possible to avoid the tilting of the door or the application of significant forces on the vertical guide rails.

Ainsi, en position verticale de la porte, son poids est supporté par le premier élément de guidage définissant un axe de support sensiblement vertical, et, lors d'un basculement en ouverture, la butée du système de guidage sur le rail de guidage se fait avec le second élément de guidage, qui décalé par rapport à la verticale de la porte, définit ainsi un axe d'appui incliné de façon importante par rapport à l'axe d'application de la force de traction.Thus, in the vertical position of the door, its weight is supported by the first guide element defining a substantially vertical support axis, and, during an opening swing, the stop of the guide system on the guide rail is with the second guide element, which is shifted by relative to the vertical of the door, thus defines a bearing axis inclined significantly with respect to the axis of application of the tensile force.

Un perfectionnement prévoit que le dispositif selon l'invention comporte au moins un système de compression, ledit système étant, en position verticale de la porte, dans un état comprimé entre la porte et au moins une entretoise. Ce système de compression applique sur l'entretoise une force perpendiculaire à son axe de rotation. Lors d'un basculement en ouverture de la porte, cette force impose le maintien des positions relatives des éléments de guidage dans le rail de guidage jusqu'à l'arrivée à un état d'équilibre dudit système de compression, c'est-à-dire que le second élément de guidage est maintenu en contact avec la partie interne supérieure du rail de guidage lors d'un basculement en ouverture de la porte depuis la position de fermeture de la porte jusqu'à ce que le système de compression atteigne son état d'équilibre. Ce maintien du contact entre le second élément de guidage et la partie supérieure interne du rail de guidage sur une certaine distance en basculement d'ouverture de la porte permet de conserver un axe d'appui incliné de manière importante le plus longtemps possible. Lorsque le système de compression atteint son équilibre, le poids de la porte associé à l'inclinaison de cette-ci d'une part, et à la liberté en rotation de l'entretoise d'autre part, impose au second élément de guidage de venir en contact avec la partie inférieure interne du rail de guidage et de soutenir le poids de la porte conjointement avec le premier élément de guidage, l'axe d'appui n'étant dès lors plus défini à l'aide dudit second élément de guidage seul.An improvement provides that the device according to the invention comprises at least one compression system, said system being, in the vertical position of the door, in a compressed state between the door and at least one spacer. This compression system applies on the spacer a force perpendicular to its axis of rotation. When switching the door open, this force imposes the maintenance of the relative positions of the guide elements in the guide rail until the equilibrium state of said compression system is reached, that is to say that is, the second guide member is held in contact with the upper inner part of the guide rail when the door is tilted to open from the closed position of the door until the compression system reaches its end. steady state. This maintenance of the contact between the second guide element and the inner upper part of the guide rail over a certain opening swing distance of the door makes it possible to maintain a bearing axis inclined significantly as long as possible. When the compression system reaches its equilibrium, the weight of the door associated with the inclination of the latter on the one hand, and the freedom of rotation of the spacer on the other hand, imposes on the second guide member contacting the inner lower part of the guide rail and supporting the weight of the door in conjunction with the first guide element, the support axis therefore no longer being defined by means of said second guide element alone.

Dans une variante d'application du système de compression, le dispositif selon l'invention comporte une pièce intermédiaire, cette pièce intermédiaire coopérant d'une part en butée avec l'entretoise et d'autre part avec le système de compression. Dans cette variante, la rotation de l'entretoise en fin de fermeture de la porte amène cette dernière en butée contre la pièce intermédiaire dans un premier temps puis impose une compression du système de compression par ladite pièce intermédiaire dans un second temps, et ce jusqu'à fermeture de la porte. Lors d'un basculement en ouverture, la pièce intermédiaire est inversement entraînée par le système de compression et impose le maintien de l'entretoise selon une orientation telle que le second élément de guidage et le premier élément de guidage sont maintenus dans leurs positions relatives.In an alternative application of the compression system, the device according to the invention comprises an intermediate piece, this intermediate piece cooperating on the one hand in abutment with the spacer and on the other hand with the compression system. In this variant, the rotation of the spacer at the end of closing of the door brings the latter into abutment against the intermediate piece at first and then imposes a compression of the compression system by said intermediate part in a second time, and until the closing of the door. During an opening swing, the intermediate piece is inversely driven by the compression system and requires maintaining the spacer in such an orientation that the second guide member and the first guide member are maintained in their relative positions.

Un perfectionnement prévoit que dans au moins un système de guidage, un axe de rotation de l'entretoise est distant des éléments de guidage d'une part et de la porte d'autre part. De préférence cet axe de rotation est situé à un niveau inférieur à l'axe du rail de guidage horizontal coopérant avec le ou les éléments de guidage dudit système de guidage. Cet écart entre le rail de guidage et l'axe de rotation de l'entretoise permet un positionnement de la porte horizontalement, c'est-à-dire en position d'ouverture, au niveau dudit rail de guidage, évitant ainsi l'encombrement imposé par la porte en position ouverte au dessus du rail de guidage tel que dans l'art antérieur. Avantageusement, l'écart entre l'axe de rotation de l'entretoise et la porte est égal à l'écart entre ledit axe de rotation et le rail de guidage.An improvement provides that in at least one guide system, an axis of rotation of the spacer is spaced from the guide elements on the one hand and the door on the other hand. Preferably this axis of rotation is located at a level below the axis of the horizontal guide rail cooperating with the guide element or elements of said guide system. This gap between the guide rail and the axis of rotation of the spacer allows positioning of the door horizontally, that is to say in the open position, at said guide rail, thus avoiding clutter imposed by the door in the open position above the guide rail as in the prior art. Advantageously, the distance between the axis of rotation of the spacer and the door is equal to the distance between said axis of rotation and the guide rail.

Selon une variante avantageuse, la dite entretoise (ou chariot) comporte deux parties articulées l'une par rapport à l'autre, selon un axe horizontal, transversal à la direction de déplacement de ladite entretoise.According to an advantageous variant, said spacer (or carriage) comprises two parts articulated with respect to each other, along a horizontal axis, transverse to the direction of movement of said spacer.

Plus, précisément, l'entretoise comporte :

  • une première partie associée aux deux éléments de guidage ;
  • une seconde partie, en forme de L, articulée sur :
    • ∘ la première partie ;
    • ∘ la porte d'autre part ;
    • ∘ les moyens d'entrainement de la porte.
More precisely, the spacer comprises:
  • a first part associated with the two guide elements;
  • a second part, L-shaped, articulated on:
    • ∘ the first part;
    • ∘ the door on the other hand;
    • ∘ the drive means of the door.

La première partie est longiligne et les éléments de guidage sont montés articulés à ses extrémités.The first part is elongated and the guide elements are mounted articulated at its ends.

La seconde partie est en forme de L, à deux branches, l'extrémité supérieure d'une première branche étant articulée sensiblement au milieu de la première partie, le coin reliant les deux branches étant articulé sur les moyens d'entrainement et l'extrémité de la seconde branche étant articulé sur la porte. En outre, le dispositif comporte d'une part un organe de butée mobile associé à la porte et d'autre part une butée fixe disposée sur la partie fixe de la structure fixe sur laquelle la porte est montée, ladite butée mobile étant apte à porter contre ladite butée fixe dans la toute première partie du déplacement de la porte, à l'ouverture et à la fermeture.The second part is L-shaped, with two branches, the upper end of a first branch being articulated substantially in the middle of the first part, the corner connecting the two branches being articulated on the drive means and the end the second branch being articulated on the door. In addition, the device comprises on the one hand a movable abutment member associated with the door and on the other hand a fixed abutment disposed on the fixed part of the fixed structure on which the door is mounted, said movable abutment being able to carry against said fixed stop in the very first part of the movement of the door, opening and closing.

De préférence, la butée mobile est un galet monté à rotation libre sur un prolongement supérieur de la pièce d'interface du système de guidage.Preferably, the movable stop is a roller mounted to rotate freely on an upper extension of the interface piece of the guide system.

L'invention porte également sur un ensemble comprenant le dispositif de l'invention décrit ci-dessus et des rails de guidage verticaux et horizontaux, les systèmes de guidage étant complémentaires de rails de guidage, en position verticale de la porte, les premiers et seconds éléments de guidage d'un système de guidage étant en contact respectivement avec une surface interne supérieure et une surface interne inférieure d'un rail de guidage horizontal.The invention also relates to an assembly comprising the device of the invention described above and vertical and horizontal guide rails, the guide systems being complementary to guide rails, in the vertical position of the door, the first and second guide members of a guide system respectively in contact with an upper inner surface and a lower inner surface of a horizontal guide rail.

La figure 1 représente une vue schématique d'un dispositif de l'art antérieur.The figure 1 represents a schematic view of a device of the prior art.

Un dispositif 1 de porte basculante est intégré à une structure 2, par exemple un garage 2 comportant une ouverture 3, afin d'obstruer ou libérer cette ouverture 3 et donc permettre ou interdire l'accès à l'intérieur de ladite structure 2.A door 1 device is integrated in a structure 2, for example a garage 2 having an opening 3, to obstruct or release this opening 3 and thus allow or prohibit access to the interior of said structure 2.

Un tel dispositif comporte une porte 4, par exemple une porte 4 de garage 2, de forme sensiblement rectangulaire et complémentaire de l'ouverture 3. Une telle porte 4 présente deux faces planes opposées, une face arrière 5 et une face avant 6. La porte 4 comporte un coté supérieur 7, un coté inférieur 8 opposé au coté supérieur 7, et deux cotés latéraux 9 reliant le coté supérieur 7 et le coté inférieur 8.Such a device comprises a door 4, for example a door 4 of garage 2, of substantially rectangular shape and complementary to the opening 3. Such a door 4 has two opposite planar faces, a rear face 5 and a front face 6. The door 4 comprises an upper side 7, a lower side 8 opposite the upper side 7, and two lateral sides 9 connecting the upper side 7 and the lower side 8.

La porte 4 est montée dans un chambranle intégré à la structure ou fixé sur elle et destiné à la recevoir. Un dispositif de guidage 10, par exemple des rails de guidage 10 intégrés au chambranle, coopère avec des éléments de guidage 11 de la porte 4 afin de la guider et permettre son basculement.The door 4 is mounted in a frame integral with the structure or fixed on it and intended to receive it. A guide device 10, for example guide rails 10 integrated with the door frame, cooperates with guide elements 11 of the door 4 to guide and allow it to tilt.

En position de fermeture, la porte 4 est sensiblement verticale et obstrue l'ouverture 3. En position d'ouverture, libérant l'ouverture 3, la porte 4 est située le long d'un plafond 12.In the closed position, the door 4 is substantially vertical and obstructs the opening 3. In the open position, releasing the opening 3, the door 4 is located along a ceiling 12.

Les éléments de guidage 11 se présentent généralement sous la forme de poulies 11 montées sur la porte 4. Ces poulies sont insérées dans les rails de guidage 10 et coopèrent avec ces derniers pour guider la porte 4 en basculement. Pour cela, le dispositif de guidage 10 comporte des rails de guidages verticaux 1 0A situés de chaque coté vertical de l'ouverture 3 et des rails de guidage horizontaux 10B situés le long du plafond 12 de la structure 2.The guide elements 11 are generally in the form of pulleys 11 mounted on the door 4. These pulleys are inserted into the guide rails 10 and cooperate with the latter to guide the door 4 tilting. For this, the guide device 10 comprises vertical guide rails 1 0A located on each vertical side of the opening 3 and horizontal guide rails 10B located along the ceiling 12 of the structure 2.

Des éléments de guidage 11 sont montés proche du coté supérieur 7 et proche du coté inférieur 8 de chaque coté latéral 9 de la porte 4. Il y a ainsi deux éléments de guidage supérieurs 11 B montés proches du coté supérieur 7 de la porte 4 et coopérant avec les rails de guidage horizontaux 10B et deux éléments de guidage inférieurs 11 A montés proches du coté inférieur 8 de la porte 4 et coopérant avec les rails de guidage verticaux 10A.Guiding elements 11 are mounted close to the upper side 7 and close to the lower side 8 of each lateral side 9 of the door 4. There are thus two upper guide members 11 B mounted close to the upper side 7 of the door 4 and cooperating with the horizontal guide rails 10B and two lower guide members 11A mounted near the lower side 8 of the door 4 and cooperating with the vertical guide rails 10A.

Afin de faciliter le basculement de la porte 4, chaque élément de guidage inférieur 11 A est relié par un élément de liaison 13, par exemple un câble ou autre, à un dispositif d'entraînement 14, par exemple un contrepoids 14. Ce contrepoids 14 applique sur la porte 4 au niveau des éléments de guidage inférieurs 11 A une force d'entraînement 15 d'axe vertical et destinée à s'opposer au poids de la porte 4.In order to facilitate the tilting of the door 4, each lower guide element 11 A is connected by a connecting element 13, for example a cable or the like, to a driving device 14, for example a counterweight 14. This counterweight 14 applied to the door 4 at the lower guide elements 11 A drive force 15 of vertical axis and intended to oppose the weight of the door 4.

La figure 2 représente une vue en coupe latérale schématique d'un dispositif selon l'invention en position fermée.The figure 2 represents a schematic side sectional view of a device according to the invention in the closed position.

Le dispositif 1 selon l'invention comporte une porte 4 telle que connue de l'art antérieur. En revanche, le dispositif selon l'invention comporte au moins deux systèmes de guidage 16 associés à la porte 4 proches du coté supérieur 7 et proches respectivement des deux cotés latéraux 9 de la porte 4. Le système de guidage 16 de l'invention remplace l'élément de guidage supérieur 11 B connu de l'art antérieur.The device 1 according to the invention comprises a door 4 as known from the prior art. On the other hand, the device according to the invention comprises at least two guiding systems 16 associated with the door 4 close to the upper side 7 and close respectively to the two lateral sides 9 of the door 4. The guiding system 16 of the invention replaces the upper guide element 11 B known from the prior art.

Pour des raisons de compréhension, la suite de la description n'est effectuée que sur un seul système de guidage 16, étant évident qu'un tel système de guidage 16 est installé de chaque coté latéral 9 de la porte 4 en partie supérieure 7 de ladite porte et que les éléments de guidage inférieurs 11 A sont eux de toute forme et fonctionnement connu de l'homme de l'art, par exemple tel que dans l'art antérieur présenté ci-dessus.For reasons of understanding, the following description is performed only on a single guiding system 16, being obvious that such a guiding system 16 is installed on each lateral side 9 of the door 4 in the upper part 7 of said door and that the lower guide elements 11A are of any form and operation known to those skilled in the art, for example as in the prior art presented above.

Le système de guidage 16 selon l'invention comporte un premier élément de guidage 17 similaire à l'élément de guidage supérieur 11 B tel que connu de l'art antérieur, ainsi qu'un élément de guidage secondaire 18. Le premier élément de guidage 17 et le second élément de guidage 18 d'un même système de guidage 16 sont situés d'un même côté latéral 9 de la porte 4 et forment une paire d'éléments de guidage sensiblement similaires.The guide system 16 according to the invention comprises a first guide element 17 similar to the upper guide element 11 B as known from the prior art, as well as a secondary guide element 18. The first guide element 17 and the second guide element 18 of the same guide system 16 are located on the same lateral side 9 of the door 4 and form a pair of substantially similar guide elements.

Le système de guidage 16 comporte une entretoise 19 mobile et montée sur une pièce d'interface 20.The guide system 16 comprises a spacer 19 movable and mounted on an interface piece 20.

La pièce d'interface 20 est fixée proche du coté supérieur 7 de la porte 4 et sur la face arrière 5 de cette dernière. Elle comporte deux branches 21,ou flasques 21, munies chacune d'un orifice 22 circulaire. L'entretoise 19 comporte un moyeu 23 complémentaire des orifices 22 et montée en rotation dans ces derniers, c'est-à-dire que l'entretoise 19 est montée mobile en rotation sur la pièce d'interface 20 selon un axe de rotation 24 défini par le moyeu 23 et passant par le centre des orifices 22.The interface piece 20 is fixed close to the upper side 7 of the door 4 and on the rear face 5 of the latter. It comprises two branches 21, or flanges 21, each provided with a circular orifice 22. The spacer 19 has a hub 23 complementary to the orifices 22 and mounted in rotation in the latter, that is to say that the spacer 19 is rotatably mounted on the interface part 20 according to an axis of rotation 24 defined by the hub 23 and passing through the center of the orifices 22.

Le montage de l'entretoise 19 décrit ici n'est pas limitatif de la portée de l'invention et cette dernière pourrait être montée en rotation directement sur la porte 4.The mounting of the spacer 19 described here is not limiting the scope of the invention and the latter could be mounted in rotation directly on the door 4.

Le premier élément de guidage 17 et le second élément de guidage 18 sont tous deux fixés sur l'entretoise 19. Dans le cas d'éléments de guidage 17 et 18 sous forme de poulies, ils sont montés en rotation sur l'entretoise 19 selon des axes de rotation parallèle à l'axe de rotation de l'entretoise.The first guide element 17 and the second guide element 18 are both fixed on the spacer 19. In the case of guide elements 17 and 18 in the form of pulleys, they are rotatably mounted on the spacer 19 according to FIG. axes of rotation parallel to the axis of rotation of the spacer.

L'entretoise 19 (figures 2 et 3) possède une forme trapézoïdale plate présentant deux faces principales opposées qui s'étendent dans un plan vertical et perpendiculaire au plan de la porte 4. Un côté supérieur 47 de l'entretoise 19, au niveau de ses deux extrémités distales, porte respectivement les deux éléments de guidage 17 et 18, tandis que qu'à proximité de son côté inférieur 27 et dans l'alignement vertical du premier élément de guidage 17 est situé l'axe de rotation de l'entretoise 19. Les deux éléments de guidage 17 et 18 sont séparés d'une distance fixe.The spacer 19 ( figures 2 and 3 ) has a flat trapezoidal shape having two opposite major faces which extend in a vertical plane and perpendicular to the plane of the door 4. An upper side 47 of the spacer 19, at its two distal ends, respectively carries the two 17 and 18, while in the vicinity of its lower side 27 and in the vertical alignment of the first guide member 17 is located the axis of rotation of the spacer 19. The two guide members 17 and 18 are separated by a fixed distance.

Le premier élément de guidage 17 est de préférence monté sur l'entretoise 19 afin d'être disposé dans l'alignement vertical de l'élément de guidage inférieur 1 1 A lorsque la porte est en position verticale.The first guide member 17 is preferably mounted on the spacer 19 to be disposed in the vertical alignment of the lower guide member 11A when the door is in a vertical position.

Le second élément de guidage 18 est lui monté sur l'entretoise 19 décalé par rapport au plan de la face arrière 5 de la porte 4 lorsque cette dernière est en position verticale. Typiquement, en position verticale de la porte 4, le second élément de guidage 18 est en retrait par rapport à la face arrière 5 de la porte. En regard de la figure 2, ce décalage procure un axe d'appui 25 pour la porte 4, lors d'un basculement en ouverture à partir de sa position verticale. L'axe d'appui est incliné, par exemple d'un angle 29, par rapport à un axe d'application 26 vertical de la force d'entraînement 15.The second guide member 18 is mounted on the spacer 19 offset from the plane of the rear face 5 of the door 4 when the latter is in the vertical position. Typically, in the vertical position of the door 4, the second guide element 18 is set back relative to the rear face 5 of the door. With regard to the figure 2 this offset provides a support axis 25 for the door 4, during an opening swing from its vertical position. The support axis is inclined, for example at an angle 29, relative to a vertical axis of application 26 of the driving force 15.

L'axe d'appui 25 de la porte 4 passe d'une part par le point d'application de la force 15 sur l'élément de guidage inférieur 11 A et d'autre part par le point d'application de la force de résistance généré par la butée du système de guidage 16 contre une partie interne supérieure 28 du rail de guidage horizontal 10B.The bearing axis 25 of the door 4 passes on the one hand by the point of application of the force 15 on the lower guide element 11 A and on the other by the point of application of the force of resistance generated by the stop of the guide system 16 against an upper inner portion 28 of the horizontal guide rail 10B.

Le point d'application de la force 15 correspond au point d'ancrage de l'élément de liaison 13 sur la porte 4, c'est-à-dire sur l'élément de guidage inférieur 11 A.The point of application of the force 15 corresponds to the anchoring point of the connecting element 13 on the door 4, that is to say on the lower guide element 11 A.

Le point d'application de la force de résistance généré par la butée du système de guidage 16 sur la partie interne supérieure 28 du rail de guidage horizontal 10B correspond au point de contact entre le système de guidage 16 et ladite partie interne supérieure 28 dudit rail de guidage 10B lorsque la force de traction 15 est appliquée sur la porte 4.The point of application of the resistance force generated by the abutment of the guide system 16 on the upper inner portion 28 of the horizontal guide rail 10B corresponds to the point of contact between the guide system 16 and said upper inner portion 28 of said rail 10B when the traction force is applied to the door 4.

Lors de l'application de la force 15 sur la porte 4 en position verticale, le système de guidage 16 bute contre la partie interne supérieure 28 du rail de guidage horizontal 10B. Cette butée génère une force de résistance s'opposant au soulèvement de la porte 4 et engendre le basculement de cette dernière. Le positionnement du second élément de guidage 18 par rapport à la face arrière 5 de la porte 4, c'est-à-dire décalé en retrait par rapport à ladite face arrière 5, engendre un décalage vers l'arrière du point d'application de cette force de résistance de par la participation dudit second élément de guidage 18 à la butée du système de guidage 16 sur la partie interne supérieure 28. Ce décalage du point d'application de la force de résistance vers l'arrière engendre un axe d'appui 25 incliné par rapport à l'axe 26 d'application de la force de traction 15 en position verticale de la porte. Cette inclinaison de l'axe d'appui 25 favorise I basculement de la porte 4 vers l'arrière en direction du plafond malgré l'application de la force de traction 15 verticale.When the force is applied to the door 4 in the vertical position, the guiding system 16 abuts against the upper inner portion 28 of the horizontal guide rail 10B. This stop generates a resistance force opposing the lifting of the door 4 and causes the tilting of the latter. The positioning of the second guide element 18 relative to the rear face 5 of the door 4, that is to say offset back from said rear face 5, causes a rearward shift of the application point. this resistance force by the participation of said second guide member 18 to the abutment of the guide system 16 on the upper inner portion 28. This shift of the point of application of the resistance force towards the rear generates an axis d support 25 inclined relative to the axis 26 for applying the pulling force 15 in the vertical position of the door. This inclination of the support pin 25 promotes I tilting of the door 4 rearward towards the ceiling despite the application of the vertical pulling force.

Dans un perfectionnement, le système de guidage 16 comporte un moyen de limitation 30 de la rotation de l'entretoise 19 par rapport à la porte 4.In an improvement, the guiding system 16 includes a means 30 for limiting the rotation of the spacer 19 with respect to the door 4.

Les éléments de guidages 17 et 18 étant montés à des emplacements fixes sur l'entretoise 19, et éventuellement libre en rotation, la rotation de l'entretoise 19 détermine la position respective des éléments de guidage 17 et 18 par rapport à ladite porte 4.The guide elements 17 and 18 being mounted at fixed locations on the spacer 19, and possibly free in rotation, the rotation of the spacer 19 determines the respective position of the guide elements 17 and 18 with respect to said door 4.

Dans le mode de réalisation représenté sur la figure 2, l'entretoise 19 comporte un moyen de butée 31 coopérant avec la face arrière 5 de la porte 4 afin de bloquer sa rotation lorsque ladite porte 4 est en position verticale. Dans cette disposition, le second élément de guidage 18 est situé au dessus, selon un plan horizontal, du premier élément de guidage 17 de telle sorte qu'en position verticale de la porte, le plan horizontal 32 tangent à l'extrémité supérieure 33 du second élément de guidage 18 est au dessus du plan horizontal 34 tangent à une extrémité supérieure 35 du premier élément de guidage 17. Typiquement, le second élément de guidage 18 est maintenu en contact avec la partie interne supérieure 28 du rail de guidage 10B alors que le premier élément de guidage 17 est lui maintenu éloigné de ladite partie interne supérieure 28 du rail de guidage 10B.In the embodiment shown on the figure 2 , the spacer 19 comprises a stop means 31 cooperating with the rear face 5 of the door 4 in order to block its rotation when said door 4 is in the vertical position. In this arrangement, the second guide element 18 is located above, in a horizontal plane, of the first guide element 17 so that in the vertical position of the door, the horizontal plane 32 tangents to the upper end 33 of the second guide member 18 is above the horizontal plane 34 tangential to an upper end 35 of the first guide member 17. Typically, the second guide member 18 is held in contact with the upper inner portion 28 of the guide rail 10B while the first guide member 17 is kept away from said upper inner portion 28 of the guide rail 10B.

Lors d'un basculement de la porte 4 depuis sa position fermée, la mise en butée du système de guidage 16 sur la partie interne supérieure 28 du rail de guidage 10B, déterminant l'axe d'appui 25 de la porte 4, se fait donc uniquement au niveau du contact entre le second élément de guidage 18 et ladite partie interne supérieure 28 du rail de guidage 10B. L'angle 29 entre l'axe d'appui 25 et l'axe d'application 26 de la force de traction 15 est donc beaucoup plus grand qu'en cas de butée simultanée des deux éléments de guidage 17 et 18 sur la partie interne supérieure 28 du rail de guidage 1 0B, et pour laquelle l'angle serait alors plus petit.When the door 4 is tilted from its closed position, the abutment of the guide system 16 on the upper internal part 28 of the guide rail 10B, determining the bearing axis 25 of the door 4, is therefore only at the contact between the second guide member 18 and said upper inner portion 28 of the guide rail 10B. The angle 29 between the bearing axis 25 and the axis of application 26 of the traction force 15 is therefore much greater than in case of simultaneous stop of the two guide members 17 and 18 on the upper inner portion 28 of the guide rail 1 0B, and for which the angle would be smaller.

Afin de conserver la porte 4 verticale dans sa position de fermeture, c'est-à-dire que la force s'opposant verticalement au poids de la porte 4 soit située sur ou proche d'un axe vertical passant par le centre de gravité de la porte 4, seul le premier élément de guidage 17 situé proche de la porte 4 supporte ledit poids de la porte 4. Typiquement, en position verticale de la porte 4, seul le premier élément de guidage 17 est en contact avec une partie interne inférieure 37 du rail de guidage 10B, le plan horizontal 38 tangent à une extrémité inférieure 39 du second élément de guidage 18 étant au dessus d'un plan horizontal 40 tangent à l'extrémité inférieure 41 du premier élément de guidage 17. Si le second élément de guidage 17 devait participer également au support de la porte 4 dans sa position verticale, le non alignement selon un axe vertical entre le centre de gravité de la porte 4 et le point d'application de la force assurant le support de la porte entraînerait un basculement du coté inférieur 8 de la porte 4 vers l'intérieur de la structure 2. Dans l'art antérieur, ce basculement est empêché par une butée de l'élément de guidage inférieur 1 1A dans le rail de guidage vertical 10A, ce qui est néfaste au bon coulissement des éléments de guidages 11 dans lesdits rails de guidage 10.In order to keep the vertical door 4 in its closed position, that is to say that the force opposing vertically the weight of the door 4 is located on or near a vertical axis passing through the center of gravity of the door 4, only the first guide element 17 located near the door 4 supports said weight of the door 4. Typically, in the vertical position of the door 4, only the first guide element 17 is in contact with a lower internal part 37 of the guide rail 10B, the horizontal plane 38 tangential to a lower end 39 of the second guide member 18 being above a horizontal plane 40 tangential to the lower end 41 of the first guide member 17. If the second element 17 should also participate in the support of the door 4 in its vertical position, the non-alignment along a vertical axis between the center of gravity of the door 4 and the point of application of the force ensuring the support of the door would cause a tilting of the lower side 8 of the door 4 towards the inside of the structure 2. In the prior art, this tilting is prevented by a stop of the lower guide element 1 1A in the vertical guide rail 10A, which is detrimental to the smooth sliding of the guide elements 11 in said guide rails 10.

La figure 3 représente une vue éclatée de l'invention, le système de guidage étant pourvu d'un perfectionnement.The figure 3 is an exploded view of the invention, the guide system being provided with an improvement.

Selon ce perfectionnement, le dispositif 1 selon l'invention comporte au moins un système de compression 42. En position verticale de la porte 4, ce système de compression 42 est maintenu dans un état comprimé entre la porte 4 et l'entretoise 19. Le système de compression 42 peut se présenter sous toute forme adaptable par l'homme du métier telle qu'un plot 42 présentant une surface bombée et réalisée en élastomère déformable à mémoire de forme.According to this improvement, the device 1 according to the invention comprises at least one compression system 42. In the vertical position of the door 4, this compression system 42 is maintained in a compressed state between the door 4 and the spacer 19. The compression system 42 can present itself in any form adaptable by those skilled in the art such as a stud 42 having a curved surface and made of deformable elastomeric shape memory.

Dans le mode de réalisation décrit ici, une butée 43, par exemple une vis 43, est prévue sur le moyeu 23 de l'entretoise 19. Cette butée 43 est complémentaire d'une pièce intermédiaire 44 montée en rotation sur le moyeu 23. Cette pièce intermédiaire comporte un renfoncement 45 de forme complémentaire à la butée 43 de sorte que lors d'un basculement en fermeture de la porte 4, la rotation de l'entretoise 19 par rapport à ladite porte 4 amène ladite butée 43 à venir se loger dans ledit renfoncement 45. Si, une fois la butée 43 logée dans le renfoncement 45, la rotation de l'entretoise 19 continue, ladite butée 43 entraîne en rotation la pièce intermédiaire 44. Lors de cette rotation, la pièce intermédiaire 44 est amenée au contact du système de compression 42 et comprime ce dernier jusqu'à ce que celui soit en état comprimé et bloque la rotation de l'entretoise.In the embodiment described here, a stop 43, for example a screw 43, is provided on the hub 23 of the spacer 19. This stop 43 is complementary to an intermediate part 44 rotatably mounted on the hub 23. intermediate piece has a recess 45 of complementary shape to the stop 43 so that during a tilting closing of the door 4, the rotation of the spacer 19 relative to said door 4 causes said stop 43 to be housed in said recess 45. If, once the stop 43 housed in the recess 45, the rotation of the spacer 19 continues, said stop 43 rotates the intermediate piece 44. During this rotation, the intermediate piece 44 is brought into contact compression system 42 and compresses the latter until that is in a compressed state and blocks the rotation of the spacer.

Les figures 4A à 4C représentent les différentes étapes d'un basculement de la porte selon l'invention en regard de la vue de détail d'un système de guidage en fonctionnement et selon le perfectionnement de la figure 3.The Figures 4A to 4C represent the different stages of a swinging of the door according to the invention with regard to the detailed view of a guidance system in operation and according to the improvement of the figure 3 .

La figure 4A montre la porte 4 en position verticale, obturant le passage 3. Dans cette position, le premier élément de guidage 17 est seul en contact avec la partie interne inférieure 37 du rail de guidage 10B et sensiblement à la verticale de l'élément de guidage inférieur 1 1A. Le second élément de guidage 18 est lui seul en contact avec la partie interne supérieure 28 du rail de guidage 10B. La butée 43 est logée dans le renfoncement 45 et maintient la pièce intermédiaire 44 en position, comprimant la pièce de compression 42.The Figure 4A shows the door 4 in vertical position, closing the passage 3. In this position, the first guide member 17 is alone in contact with the lower inner portion 37 of the guide rail 10B and substantially vertically to the lower guide member 1 1A. The second guide member 18 is alone in contact with the upper inner portion 28 of the guide rail 10B. The abutment 43 is housed in the recess 45 and holds the intermediate piece 44 in position, compressing the compression piece 42.

Lors d'un basculement en ouverture de la porte 4 depuis sa position verticale, le second élément de guidage 18 judicieusement positionné en décalage détermine l'axe d'appui 25 initial, ce qui permettra le basculement de la porte 4 dans la bonne direction.During a tilting opening of the door 4 from its vertical position, the second guide member 18 judiciously positioned offset determines the initial support axis 25, which will allow the tilting of the door 4 in the right direction.

La figure 4B montre le dispositif selon l'invention dans un état proche de l'état d'équilibre du système de compression 42. Après un début de basculement en ouverture de la porte 4, le système de compression 42 n'est que partiellement comprimé, la rotation de l'entretoise 19 par rapport à la porte 4 ne permet plus le maintien de la pièce intermédiaire 44 contre le système de compression 42. Ce dernier repousse ladite pièce intermédiaire 44 qui, en coopération avec la butée 43, maintient l'entretoise 19 de façon que le second élément de guidage 18 reste en contact avec la partie interne supérieure 28 du rail de guidage 10B, tandis que le premier élément de guidage 17 reste en contact avec la partie interne inférieure dudit rail de guidage 10B.The Figure 4B shows the device according to the invention in a state close to the equilibrium state of the compression system 42. After a beginning of tilting in opening of the door 4, the compression system 42 is only partially compressed, the rotation the spacer 19 with respect to the door 4 no longer allows the intermediate part 44 to be held against the compression system 42. The latter pushes back said intermediate piece 44 which, in cooperation with the stop 43, holds the spacer 19 of so that the second guide member 18 remains in contact with the upper inner portion 28 of the guide rail 10B, while the first guide member 17 remains in contact with the lower inner portion of said guide rail 10B.

Le relâchement du système de compression 42 permet d'assurer un angle 29 important durant tout le début de course en basculement d'ouverture de la porte 4. Typiquement, cela permet d'éviter que le second élément de guidage 18 soit entraîné par le poids de la porte 4 en contact avec la partie interne inférieure du rail 10B dès le début du basculement de la porte 4.The release of the compression system 42 makes it possible to provide a large angle 29 during the entire start of the opening swinging stroke of the door 4. Typically, this makes it possible to prevent the second guiding element 18 from being driven by the weight of the door 4 in contact with the lower inner part of the rail 10B from the beginning of the tilting of the door 4.

La figure 4C montre un dispositif selon l'invention dans une position d'ouverture complète de la porte.The figure 4C shows a device according to the invention in a fully open position of the door.

Dans cette position, les deux éléments de guidage 17 et 18 sont uniquement en contact avec la partie interne inférieure 37 du rail de guidage 10B et participent conjointement au soutien de la porte 4. Par ailleurs, le positionnement de l'axe de rotation 24 de l'entretoise 19 est tel qu'il existe d'une part des écarts 46 et 48 constant entre ledit axe 24 de rotation et respectivement les éléments de guidage 17 et 18 et, d'autre part, un écart 36 constant entre ledit axe 24 de rotation et la face arrière 5 de la porte 4. Ces écarts 36 et 46 associés à la rotation de l'entretoise 19 au cours du basculement évitent un encombrement de la porte 4 au dessus du rail de guidage 10B en permettant le logement de la porte 4 dans sa position horizontale au même niveau que lesdits rails de guidage 10B.In this position, the two guide elements 17 and 18 are only in contact with the lower inner portion 37 of the guide rail 10B and participate jointly in the support of the door 4. Moreover, the positioning of the axis of rotation 24 of the spacer 19 is such that there are on the one hand constant gaps 46 and 48 between said axis 24 of rotation and respectively the guide elements 17 and 18 and, secondly, a constant distance 36 between said axis 24 of rotation and the rear face 5 of the door 4. These differences 36 and 46 associated with the rotation of the spacer 19 during the tilting avoid a congestion of the door 4 above the guide rail 10B allowing the housing of the door 4 in its horizontal position at the same level as said guide rails 10B.

La pièce intermédiaire 44 est maintenue dans une position sensiblement horizontale, afin d'éviter sa rotation sous l'effet de la gravité, par tout moyen connu de l'homme de l'art, par exemple par des épaulements interne prévus sur des faces internes des branches 21 de la pièce d'interface 20 sur lesquels la pièce intermédiaire vient reposer en position horizontale de la porte ou encore par des rainures de guidage sur les branches 21 limitant la rotation de ladite pièce intermédiaire ou tout autre système aisément adaptable par l'homme de l'art.The intermediate piece 44 is held in a substantially horizontal position, in order to prevent its rotation under the effect of gravity, by any means known to those skilled in the art, for example by internal shoulders provided on internal faces. branches 21 of the interface piece 20 on which the intermediate piece rests in horizontal position of the door or by guide grooves on the branches 21 limiting the rotation of said intermediate piece or any other system easily adaptable by the skilled in the art.

Il est fait référence aux figures 5A, 5B et 5C montrant une variante de réalisation de l'invention, selon chacune une vue perspective partielle d'une porte de garage et sa structure fixée aux murs (non représentés) de la construction sur laquelle est montée la porte, en positions respectives :

  • fermée (porte verticale)
  • au démarrage de l'ouverture
  • en position ouverte (horizontale).
Reference is made to FIGS. 5A, 5B and 5C showing an alternative embodiment of the invention, according to each a partial perspective view of a garage door and its structure attached to the walls (not shown) of the construction on which the door is mounted, in respective positions:
  • closed (vertical door)
  • at the start of the opening
  • in open (horizontal) position.

Les éléments identiques ou similaires à ceux des figures 1 à 4 portent les mêmes références.Elements identical or similar to those of Figures 1 to 4 bear the same references.

Selon cette variante, ladite entretoise (ou chariot) 19 comporte deux parties 50 et 51, articulées l'une par rapport à l'autre, selon un axe horizontal 52, transversal à la direction de déplacement de ladite entretoise 19 le long du rail 10 par le biais des éléments de guidage 17 et 18.According to this variant, said spacer (or carriage) 19 comprises two parts 50 and 51, articulated with respect to each other, along a horizontal axis 52, transverse to the direction of movement of said spacer 19 along the rail 10 through the guide members 17 and 18.

Plus, précisément, l'entretoise 19 comporte :

  • une première partie longiligne 50 associée aux deux éléments de guidage 17 et 18 ;
  • une seconde partie 51, en forme de L, articulée sur :
    • ∘ la première partie 50 selon un axe de rotation 52 ;
    • ∘ la porte d'autre part selon un axe de rotation 53, par la pièce 21 à section droite en U ;
    • ∘ les moyens d'entrainement 54A et 54B (liés à un moteur non représenté) de la porte 4 selon un axe de rotation 55.
More precisely, the spacer 19 comprises:
  • a first elongated portion 50 associated with the two guide members 17 and 18;
  • a second portion 51, L-shaped, articulated on:
    • The first part 50 along an axis of rotation 52;
    • The door on the other hand along an axis of rotation 53, by the U-shaped cross section piece 21;
    • ∘ the drive means 54A and 54B (linked to a motor not shown) of the door 4 along an axis of rotation 55.

La première partie 50 est longiligne et les éléments de guidage 17 et 18 sont montés articulés à ses extrémités.The first part 50 is elongate and the guide elements 17 and 18 are articulated at its ends.

La seconde partie 51 est en forme générale de L, à deux branches 56 et 57.The second part 51 is in the general shape of L, with two branches 56 and 57.

L'extrémité supérieure 56A d'une première branche 56 étant articulée (sensiblement au 2/3 de la première partie longiligne 50) selon l'axe de rotation 52. Le coin reliant les deux branches 56, 57 étant articulé sur les moyens d'entrainement 54A (axe de rotation 55). L'extrémité de la seconde branche 57 est articulé (axe de rotation 53) sur la porte 4.The upper end 56A of a first branch 56 being hinged (substantially to 2/3 of the first elongated portion 50) along the axis of rotation 52. The corner connecting the two branches 56, 57 being articulated on the means of 54A drive (rotation axis 55). The end of the second leg 57 is articulated (axis of rotation 53) on the door 4.

En outre, la seconde branche 57 de la seconde partie 51 en L comporte une patte 58 sensiblement parallèle à la première branche 56 (de la seconde partie 51 en L).In addition, the second leg 57 of the second portion 51 L comprises a lug 58 substantially parallel to the first leg 56 (of the second portion 51 L).

L'extrémité distale 58A de la patte 58 présente un bord franc 59 orthogonal proche de, ou en butée contre, un bord franc 60 de la première partie 50 longiligne.The distal end 58A of the lug 58 has a straight edge 59 orthogonal near or abutting against a straight edge 60 of the first elongate portion 50.

Enfin, toujours selon cette variante, il est prévu :

  • une butée fixe 61, solidaire d'un montant transversal 62, sensiblement à l'aplomb et au-dessus de la pièce 21 solidaire de la porte 4 et matérialisant l'axe de rotation 53 ; ladite butée fixe 61 comporte un plan d'appui 61 A incliné en pente ascendante vers l'arrière ;
  • une butée mobile 63 solidaire de la pièce 21, donc de la porte, sous la forme d'un galet 63 monté à rotation libre sur un axe 64 lui-même disposé sur des prolongements 21 A des flancs latéraux parallèles de la pièce 21
Finally, according to this variant, it is planned:
  • a fixed stop 61 secured to a transverse upright 62 substantially perpendicular to and above the part 21 integral with the door 4 and embodying the axis of rotation 53; said fixed stop 61 has a bearing plane 61 A inclined upwardly upwards;
  • a movable stop 63 secured to the part 21, and therefore to the door, in the form of a roller 63 mounted to rotate freely on an axis 64 itself disposed on extensions 21 A of the parallel lateral flanks of the part 21

Les figures 5A, 5B et 5C montrent les étapes successives d'ouverture de la porte.The FIGS. 5A, 5B and 5C show the successive steps of opening the door.

La porte étant fermée (figure 5A,) les divers éléments se trouvent dans les positions suivantes :

  • la porte est verticale
  • le galet de butée mobile 63 est à distance et en-dessous de la butée fixe 61
  • l'entretoise 19 est en bout de course dans le rail 10, en direction de la porte
  • la branche 56 du L que forme la seconde partie 51 (de l'entretoise 19) est verticale et la branche 57 dudit L est horizontale
  • la patte 58 de la seconde partie 51 est verticale
  • les bords francs respectifs de la première partie 50 d'une part et de la patte 58 d'autre part sont en butée l'un contre l'autre
  • les moyens d'entrainement 54A et 54B sont en bout de course vers la porte verticale
The door is closed ( Figure 5A ,) the various elements are in the following positions:
  • the door is vertical
  • the movable thrust roller 63 is at a distance and below the fixed stop 61
  • the spacer 19 is at the end of travel in the rail 10, in the direction of the door
  • the branch 56 of the L that forms the second part 51 (of the spacer 19) is vertical and the branch 57 of said L is horizontal
  • the leg 58 of the second part 51 is vertical
  • the respective free edges of the first part 50 on the one hand and the tab 58 on the other hand abut against each other
  • the drive means 54A and 54B are ultimately towards the vertical door

Sur la figure 5B, on a représenté une position où la porté a commencé à être entrainée par le biais des moyens d'entrainement 54A, 54B ; ces derniers se déplacent en translation vers l'arrière (opposé à la porte). Cette figure montre une position au tout début du processus d'ouverture.On the Figure 5B there is shown a position where the wear has begun to be driven through the drive means 54A, 54B; these move in translation backward (opposite the door). This figure shows a position at the very beginning of the opening process.

Les moyens d'entrainement se sont déplacés de 2 à 5 cm (valeur indicative), et ce faisant les divers éléments ont pris les positions respectives suivantes :

  • la porte est quasi verticale, avec un angle par rapport à la verticale de quelques degrés, et est légèrement (2 à 5 cm) en arrière
  • le galet de butée 63 porte contre le plan incliné 61 A de la butée fixe 61
  • l'entretoise 19 a été entrainée en translation sur le rail 10 d'une distance équivalente au déplacement des moyens d'entrainement 54A et 54B
  • la seconde partie 51 en L de l'entretoise a pivoté vers l'arrière par rapport à l'axe de rotation 55, ce qui fait que :
    • ∘ la branche 56 du L est légèrement inclinée vers l'arrière
    • ∘ la branche 57 dudit L est légèrement inclinée par rapport à l'horizontale
  • la patte 58 de la seconde partie 51 est légèrement inclinée par rapport à l'horizontale
  • les bords francs respectifs de la première partie 50 d'une part et de la patte 58 sont légèrement écartés l'un de l'autre
  • les moyens d'entrainement 54A et 54B sont translatés en arrière de quelques cm.
The training means moved from 2 to 5 cm (indicative value), and in doing so the various elements took the following respective positions:
  • the door is almost vertical, with an angle to the vertical of a few degrees, and is slightly (2 to 5 cm) back
  • the stop roller 63 bears against the inclined plane 61 A of the fixed stop 61
  • the spacer 19 has been driven in translation on the rail 10 by a distance equivalent to the displacement of the drive means 54A and 54B
  • the second L-shaped portion 51 of the spacer has pivoted rearwardly with respect to the axis of rotation 55, so that:
    • ∘ branch 56 of the L is tilted slightly backwards
    • The branch 57 of said L is slightly inclined with respect to the horizontal
  • the leg 58 of the second portion 51 is slightly inclined relative to the horizontal
  • the respective free edges of the first portion 50 on the one hand and the leg 58 are slightly apart from each other
  • the drive means 54A and 54B are translated back a few cm.

La rotation de la seconde partie 51 en L fait que l'axe 53 et donc la pièce 21, et ainsi la porte 4 subit un mouvement de translation verticale ascendant, outre un mouvement de translation en arrière.The rotation of the second portion 51 L is that the axis 53 and therefore the part 21, and thus the door 4 undergoes an upward vertical translation movement, in addition to a translation movement back.

Ce dernier mouvement ascendant fait que le galet de butée mobile 63 porte contre le plan incliné 61 A de la butée fixe 61. Ceci d'une part limite l'amplitude du mouvement ascendant de la porte et d'autre part « repousse » la porte vers l'arrière, augmentant alors l'effet de translation horizontale résultant de la translation de l'entretoise 19 à la quelle la porte est liée.This last upward movement causes the movable stop roller 63 to bear against the inclined plane 61 A of the fixed stop 61. This on the one hand limits the amplitude of the upward movement of the door and on the other hand "pushes" the door towards the rear, then increasing the horizontal translation effect resulting from the translation of the spacer 19 to which the door is linked.

La figure 5C montre les éléments pour une position totalement ouverte (ou quasi totalement ouverte) de la porte, et où :

  • la porte est horizontale ou quasi horizontale
  • l'entretoise 19 est en bout de course (ou quasiment) dans le rail 10, vers l'arrière
  • la branche 56 du L que forme la seconde partie 51 (de l'entretoise 19) est verticale et la branche 57 dudit L est horizontale
  • la patte 58 de la seconde partie 51 est verticale
  • les bords francs respectifs de la première partie 50 d'une part et de la patte 58 sont proches et/ou en butée l'un contre l'autre
  • les moyens d'entrainement 54A et 54B sont en bout de course (ou quasiment) vers l'arrière.
The Figure 5C shows the elements for a totally open (or almost completely open) position of the door, and where:
  • the door is horizontal or almost horizontal
  • the spacer 19 is at the end of travel (or almost) in the rail 10, towards the rear
  • the branch 56 of the L that forms the second part 51 (of the spacer 19) is vertical and the branch 57 of said L is horizontal
  • the leg 58 of the second part 51 is vertical
  • the respective free edges of the first part 50 on the one hand and the tab 58 are close and / or abutting against each other
  • the drive means 54A and 54B are at the end (or almost) towards the rear.
