Description

La présente invention se rapporte à un dispositif de blocage en rotation d'un ouvrant sur un encadrement.The present invention relates to a locking device in rotation of an opening on a frame.

Ce dispositif comporte un carter, fixe, dans lequel sont positionnés des moyens pour le blocage de l'ouvrant. Ces moyens comporte d'une part des moyens de retenu électromécanique (par exemple électromagnétiques : ventouse et contreplaque) et d'autre part des moyens de guidage comportant un fourreau tubulaire, fixé à l'ouvrant, dans lequel un cône est monté mobile en translation, ledit fourreau tubulaire comportant au moins deux cavités accueillant chacune une bille ainsi qu'une pièce d'arrêt, fixe, présentant au moins deux alésages complémentaires.This device comprises a housing, fixed, in which are positioned means for locking the opening. These means comprise on the one hand electromechanical retaining means (for example electromagnetic suction cup and counterplate) and on the other hand guiding means comprising a tubular sheath, fixed to the opening, in which a cone is mounted movable in translation , said tubular sheath having at least two cavities each accommodating a ball and a fixed stop member, having at least two complementary bores.

Elle concerne plus particulièrement un dispositif d'articulation à arrêt électromagnétique qui peut être utilisé en particulier comme crapaudine en partie basse d'une porte ou comme charnière.It relates more particularly to a hinge device with electromagnetic shutdown which can be used in particular as a truss at the bottom of a door or as a hinge.

Ce type de dispositif permet de bloquer une porte dans une position souhaitée une fois cette position atteinte (en général position porte ouverte à 90 °, 180 ° ou tout autre angle souhaité) à l'aide de moyens électromécaniques alimentés en courant électrique et permet de débloquer la porte en cas coupure de l'alimentation électrique des moyens électromécaniques, en particulier lors d'une incendie.This type of device makes it possible to block a door in a desired position once this position has been reached (in general door open position at 90 °, 180 ° or any other desired angle) by means of electromechanical means supplied with electric current and makes it possible to unlock the door in case of power failure of the electromechanical means, especially during a fire.

Ce genre de dispositif est en général proposé associé à d'autres dispositifs pour la même porte, en particulier un dispositif de refermeture qui permettra le retour de la porte dans une position porte fermée dès que les moyens électromécaniques ne seront plus alimentés, et éventuellement un dispositif d'amortissement de retour, par exemple un dispositif d'amortissement à freinage hydraulique, permettant de maîtriser la vitesse de retour de la porte sous l'effet du dispositif de refermeture si celui-ci n'est pas pourvu de moyen d'amortissement de retour.This type of device is generally proposed associated with other devices for the same door, in particular a reclosing device that will allow the return of the door in a closed door position as soon as the electromechanical means are no longer powered, and possibly a return damping device, for example a damping device with hydraulic braking, to control the speed of return of the door under the effect of the reclosing device if it is not provided with damping means back.

L'art antérieur connaît à ce titre la demande internationale de brevet N° WO 96/18793 qui porte sur une charnière à arrêt électromagnétique.The prior art knows in this respect the international patent application No. WO 96/18793 which relates to a hinge with electromagnetic shutdown.

Dans ce document, le premier carter, comportant les moyens électromécaniques pour le blocage électromécanique, est situé en partie supérieure du dispositif et est destiné à être fixé à l'ouvrant, alors que le second carter est situé en partie inférieure du dispositif et est destiné à être fixé à l'encadrement. Les deux carters sont donc positionnés l'un à la suite de l'autre. Par ailleurs, un fourreau porte-billes est guidé en rotation par un pallier solidaire du carter abritant les moyens de blocage de l'ouvrant, ce pallier comportant par ailleurs des trous afin de réaliser par ailleurs une pièce d'arrêt.In this document, the first housing, comprising the electromechanical means for the electromechanical blocking, is located in the upper part of the device and is intended to be fixed to the opening, while the second housing is located in the lower part of the device and is intended to to be fixed to the coaching. Both casings are therefore positioned one after the other. Furthermore, a bearing sleeve is guided in rotation by a step integral with the casing housing the locking means of the opening, this bearing further comprising holes in order to also achieve a stop piece.

L'art antérieur connaît par ailleurs la demande internationale de brevet N° WO 2008/017779 qui porte sur un dispositif d'articulation à arrêt électromagnétique dont les deux cartes sont au moins partiellement concentriques et qui est ainsi dissimulable, pour l'essentiel, dans l'ouvrant de la porte.The prior art also knows the international patent application No. WO 2008/017779 which relates to a hinge device with electromagnetic stop whose two cards are at least partially concentric and which is thus concealable, essentially, in the opening of the door.

Ce dispositif donne satisfaction car il permet de soutenir une partie du poids de l'ouvrant et par conséquent de réaliser un soutien dans la transmission des efforts entre l'ouvrant et l'encadrement, et ce, en particulier pour une utilisation comme crapaudine, en partie basse de la porte.This device is satisfactory because it allows to support part of the weight of the opening and therefore to provide support in the transmission of forces between the opening and the frame, and in particular for use as a crapaudine, in lower part of the door.

Toutefois, ce dispositif pourrait être encore amélioré pour permettre un soutien total du poids de l'ouvrant suffisamment fiable par exemple pour tenir 500 000 cycles, voire un million de cycle.However, this device could be further improved to allow a total support of the weight of the opening sufficiently reliable for example to hold 500,000 cycles or a million cycles.

L'art antérieur connaît d'autre part la demande de brevet français N° FR 2 903 445 qui porte également sur un dispositif d'articulation à arrêt électromagnétique.The prior art also knows the French patent application N ° FR 2,903,445 which also relates to a hinge device with electromagnetic shutdown.

Ce dispositif utilise une ventouse électromagnétique qui n'est pas dans l'axe de rotation de l'ouvrant. Des moyens sont donc prévus pour le transfert des efforts, mais ces transferts d'efforts risquent d'engendrer, à l'usage, une usure prématurée.This device uses an electromagnetic lock that is not in the axis of rotation of the opening. Means are therefore provided for the transfer of forces, but these efforts transfers may cause, in use, premature wear.

La présente invention entend remédier aux inconvénients de l'art antérieur en proposant un dispositif d'articulation à arrêt électromécanique à la fois compact et capable d'opérer efficacement la reprise de tout ou partie du poids de l'ouvrant.The present invention intends to overcome the drawbacks of the prior art by proposing an electromechanical stop joint device that is both compact and capable of efficiently operating the recovery of all or part of the weight of the opening.

Ainsi, ce dispositif est inaccessible dans sa quasi-totalité aux actes de malveillance ou de vandalisme tout en permettant un guidage en rotation fiable, même pour des ouvrants lourds.Thus, this device is almost inaccessible to malicious acts or vandalism while allowing reliable rotation guidance, even for heavy openings.

Par ailleurs, la présente invention entend permettre non seulement le guidage de la rotation et l'arrêt électromagnétique de la porte selon l'angle souhaité, comme précédemment, mais outre elle entend le faire avec moins de pièces mécaniques et des pièces plus simples à fabriquer, à agencer et à installer sur la porte.Furthermore, the present invention intends to allow not only the guidance of the rotation and the electromagnetic shutdown of the door according to the desired angle, as before, but in addition it intends to do so with fewer mechanical parts and simpler parts to manufacture. , to arrange and to install on the door.

Le dispositif selon l'invention entend ainsi être moins onéreux que les précédant tout en étant au moins autant, et de préférence plus, fiable que les précédents.The device according to the invention thus intends to be less expensive than the preceding while being at least as much, and preferably more, reliable than the previous ones.

Il entend en outre donner plus de liberté de réglage en fonction de la configuration de la porte.It also intends to give more freedom of adjustment depending on the configuration of the door.

La présente invention se rapporte ainsi dans son acception la plus large à un dispositif de blocage en rotation d'un ouvrant par rapport à un encadrement la revendication 1. Ce dispositif comporte un carter dans lequel sont positionnés des moyens pour le blocage de l'ouvrant, ces moyens comportant d'une part des moyens de retenu électromécanique et d'autre part des moyens de guidage comportant un fourreau tubulaire dans lequel un cône est monté mobile en translation, ledit fourreau tubulaire comportant au moins deux cavités accueillant chacune une bille ainsi qu'une pièce d'arrêt présentant au moins deux alésages complémentaires.The present invention thus relates in its broadest sense to a locking device in rotation of an opening relative to a frame claim 1. This device comprises a housing in which are positioned means for locking the opening these means comprising on the one hand electromechanical retaining means and on the other hand guiding means comprising a tubular sheath in which a cone is mounted to move in translation, said tubular sheath having at least two cavities each accommodating a ball as well as a stop member having at least two complementary bores.

Selon l'invention, ledit cône coopère avec lesdits moyens pour le blocage de l'ouvrant par l'intermédiaire d'une rotule comportant une extrémité sphérique présentant un diamètre extérieur et ladite rotule comportant en outre un rétrécissement de section avant l'extrémité sphérique dont le diamètre extérieur est inférieur à 0,95 fois le diamètre extérieur de l'extrémité sphérique, cette extrémité sphérique coopérant avec une surface d'appui qui est liée aux moyens de retenu électrique, ladite surface d'appui comportant une arête proximale au moins partiellement circulaire présentant un diamètre supérieur au diamètre extérieur du rétrécissement de section et inférieur au diamètre extérieur de l'extrémité sphérique.According to the invention, said cone cooperates with said means for locking the opening through a ball joint having a spherical end having an outer diameter and said ball further comprising a narrowing of the section before the spherical end of which the outer diameter is less than 0.95 times the outer diameter of the spherical end, this spherical end cooperating with a bearing surface which is connected to the electrical retaining means, said bearing surface having a proximal edge at least partially circular having a diameter greater than the outer diameter of the section narrowing and smaller than the outer diameter of the spherical end.

Le rétrécissement de section présente, de préférence, un diamètre extérieur de l'ordre de 0,2 à 0,8 fois le diamètre extérieur de l'extrémité sphérique et par exemple de l'ordre de 0,5 fois le diamètre extérieur de l'extrémité sphérique.The section shrinkage preferably has an outer diameter of the order of 0.2 to 0.8 times the outer diameter of the spherical end and for example of the order of 0.5 times the outer diameter of the spherical end. spherical end.

Ladite surface d'appui comporte, en outre de préférence, une arête distale au moins partiellement circulaire présentant un diamètre égal ou supérieur au diamètre extérieur de l'extrémité sphérique.Said bearing surface further preferably comprises an at least partially circular distal edge having a diameter equal to or larger than the outer diameter of the spherical end.

Cette surface d'appui est, de préférence, droite entre les deux arêtes et cette surface d'appui est, de préférence encore, orientée d'un angle compris entre 40 et 50 ° par rapport à l'axe A par lequel passe les centres des deux arêtes au moins partiellement circulaires. Elle est ainsi plus facile à usiner.This bearing surface is preferably straight between the two edges and this bearing surface is, more preferably, oriented at an angle of between 40 and 50 ° with respect to the axis A through which the centers pass. at least two partially circular edges. It is thus easier to machine.

Ladite surface d'appui est, de préférence, positionnée à l'intérieur d'un écrou fendu qui comporte sur sa face extérieure un alésage, ledit écrou fendu étant, de préférence encore, vissé par sa face extérieure à une contre-plaque coopérant avec une ventouse électromagnétique.Said bearing surface is preferably positioned inside a split nut which has on its outer face a bore, said split nut being, more preferably, screwed by its outer face to a counter-plate cooperating with an electromagnetic sucker.

Cet écrou fendu présente, de préférence, une fente d'une largeur égale ou supérieure au diamètre extérieur du rétrécissement de section.This slotted nut preferably has a slot of a width equal to or greater than the outside diameter of the section narrowing.

Dans une variante particulière, indépendamment ou en combinaison du fait que ledit cône coopère avec lesdits moyens pour le blocage de l'ouvrant par l'intermédiaire d'une rotule, lesdits moyens de guidage sont montés en rotation guidée dans ledit carter, c'est-à-dire à l'intérieur dudit carter, qui est fixe par un moyen qui est séparé de la pièce d'arrêt.In a particular variant, independently or in combination, in that said cone cooperates with said means for locking the opening by means of a ball joint, said guide means are mounted in guided rotation in said casing; that is to say inside said casing, which is fixed by a means which is separated from the stop piece.

Dans cette variante, ladite rotation guidée est, de préférence, opérée à l'aide d'au moins un roulement à billes ou d'un palier ou d'un coussinet, interposé entre d'une part ledit fourreau tubulaire et d'autre part ladite pièce d'arrêt et/ou ledit carter.In this variant, said guided rotation is preferably operated by means of at least one ball bearing or a bearing or a pad, interposed between firstly said tubular sheath and secondly said stop piece and / or said housing.

Cette rotation guidée est, de préférence, opérée à l'aide d'au moins un roulement à billes, et de préférence à l'aide de deux roulements à billes, ce(s) roulement(s) à billes étant interposé(s) :

  • pour l'un à l'extrémité supérieure dudit fourreau tubulaire entre d'une part ledit fourreau tubulaire et d'autre part ladite pièce d'arrêt et/ou ledit carter et/ou
  • pour l'autre à l'extrémité inférieure dudit fourreau tubulaire entre d'une part ledit fourreau tubulaire et d'autre part ladite pièce d'arrêt et/ou ledit carter.
This guided rotation is preferably carried out using at least one ball bearing, and preferably using two ball bearings, this (s) ball bearing (s) being interposed (s) :
  • for one at the upper end of said tubular sheath between on the one hand said tubular sheath and on the other hand said stop piece and / or said casing and / or
  • for the other at the lower end of said tubular sheath between firstly said tubular sheath and secondly said stop piece and / or said casing.

Les moyens électromécaniques comportent, de préférence, une ventouse électromagnétique positionnée, de préférence encore, à l'intérieur du carter. Ainsi, cette ventouse est fixe pendant les mouvements de rotation de l'ouvrant.The electromechanical means preferably comprise an electromagnetic lock positioned, more preferably, inside the housing. Thus, this sucker is fixed during the rotational movements of the opening.

Dans une variante tout particulière, indépendamment d'une part du fait que lesdits moyens de guidage sont montés en rotation guidée dans ledit carter par un moyen qui est séparé de la pièce d'arrêt et/ou d'autre part du fait que ledit cône coopère avec lesdits moyens pour le blocage de l'ouvrant par l'intermédiaire d'une rotule, ledit fourreau tubulaire est fixé à l'ouvrant par l'intermédiaire d'un système de réglage d'ouverture. Ce système comporte, de préférence, d'une part une goupille traversant transversalement ledit fourreau tubulaire et d'autre part un socle fixé à l'ouvrant et présentant une ouverture accueillant ledit fourreau tubulaire, ainsi que des moyens, comme par exemple au moins une vis, pour bloquer angulairement (par rapport à l'axe de rotation R) ledit socle vis-à-vis de ladite goupille (en fait le blocage se fait de préférence indirectement, par l'intermédiaire du manchon).In a very particular variant, independently of the fact that said guide means are mounted in guided rotation in said housing by a means which is separate from the stop piece and / or on the other hand because said cone cooperates with said means for locking the opening through a ball joint, said tubular sheath is fixed to the opening through an opening adjustment system. This system preferably comprises, on the one hand, a pin traversing transversely said tubular sheath and, on the other hand, a base fixed to the sash and having an opening accommodating said tubular sheath, as well as means, such as for example at least one screw, to lock angularly (relative to the axis of rotation R) said base vis-à-vis said pin (in fact the blocking is preferably indirectly through the sleeve).

La présente invention se rapporte également à une porte présentant au moins un ouvrant articulé sur un encadrement, voire deux ouvrants articulés sur un encadrement, et comportant au moins un dispositif selon l'invention.The present invention also relates to a door having at least one opening articulated on a frame, or two openings articulated on a frame, and comprising at least one device according to the invention.

Le carter est, de préférence, disposé à l'intérieur dudit ouvrant, de manière à être, pour l'essentiel, dissimulé dans l'ouvrant et à l'abri de tout acte de malveillance.The casing is preferably disposed within said opening, so as to be, for the most part, hidden in the opening and safe from any malicious act.

L'alimentation électrique des moyens électromécaniques est en outre, de préférence, dissimulée à l'intérieur dudit dispositif de manière à être, elle aussi, dissimulés et à l'abri de tout acte de malveillance.The power supply electromechanical means is further preferably concealed inside said device so as to be, too, concealed and safe from any malicious act.

Dans une variante avantageuse de l'utilisation de l'invention en tant que crapaudine, la plaque est fixée au sol.In an advantageous variant of the use of the invention as a crapaudine, the plate is fixed to the ground.

La figure 1 illustre une porte 30 selon l'invention mettant en oeuvre un dispositif 1 selon l'invention.The figure 1 illustrates a door 30 according to the invention implementing a device 1 according to the invention.

Ce dispositif est un dispositif de blocage en rotation d'un ouvrant 2 de la porte par rapport à un encadrement 3 de cette porte. L'ouvrant 2 présente bien sûr deux faces principales ainsi qu'un chant périphérique, ce chant coopérant ici en partie latérale et supérieure avec l'encadrement pour une fermeture étanche de la porte. Le chant latéral 32 de l'ouvrant 2 se trouve ainsi en vis-à-vis du chant latéral 33 de l'encadrement 3 lorsque la porte est fermée.This device is a locking device in rotation of an opening 2 of the door relative to a frame 3 of this door. The opening 2 of course has two main faces and a peripheral edge, this song cooperating here in the upper and lateral part with the frame for a sealed closure of the door. The side edge 32 of the opening 2 is thus vis-à-vis the side edge 33 of the frame 3 when the door is closed.

L'ouvrant peut être ouvert par un mouvement de rotation selon un axe vertical situé à proximité du chant latéral 32.The opening can be opened by a rotational movement along a vertical axis located near the side edge 32.

Le dispositif 1 comporte un carter 4 tubulaire, de section intérieure et extérieure circulaire et qui est fixé à l'encadrement ou au sol par l'intermédiaire d'une plaque 6, positionnée sensiblement perpendiculairement à son axe, et à laquelle il est relié fixement par collage ou soudage.The device 1 comprises a tubular casing 4, of circular inner and outer section and which is fixed to the frame or to the ground by means of a plate 6, positioned substantially perpendicularly to its axis, and to which it is fixedly connected. by gluing or welding.

Le dispositif 1 comporte des moyens électromécaniques pour le blocage électromécanique de l'ouvrant vis-à-vis du dormant dans une position souhaitée après que cette position ait été atteinte, en particulier par action manuelle contre l'ouvrant, ce blocage étant opéré grâce à l'alimentation électrique des moyens électromécaniques.The device 1 comprises electromechanical means for the electromechanical locking of the opening vis-à-vis the frame in a desired position after this position has been reached, in particular by manual action against the opening, this blocking being operated thanks to the power supply of the electromechanical means.

C'est le carter 4 qui comporte des moyens électromécaniques pour le blocage électromécanique de l'ouvrant 2.It is the casing 4 which comprises electromechanical means for the electromechanical locking of the opening 2.

Le dispositif 1 présente ainsi des câbles électriques 14, cachés dans des fourreaux, pour l'alimentation électrique des moyens électromécaniques et qui ne sont ainsi pas visibles entre l'ouvrant et le dormant.The device 1 thus has electric cables 14, hidden in sleeves, for the power supply of the electromechanical means and which are thus not visible between the opening and the frame.

La mise hors tension des moyens électromécaniques opère l'interruption du blocage, et par voie de conséquence rend possible tout mouvement de l'ouvrant.The deactivation of the electromechanical means operates the interruption of the blocking, and consequently makes possible any movement of the opening.

Dans l'exemple illustré ici le dispositif 1 constitue une crapaudine pour l'ouvrant 2, c'est-à-dire qu'il permet de transmettre en majeure partie le poids de l'ouvrant 2 à l'encadrement 3, en partie basse de l'ouvrant et plus précisément sous l'ouvrant. Au moins un autre dispositif d'articulation, pas nécessairement comme l'invention à arrêt électromécanique, est alors prévu en partie haute de la porte pour la transmission du reste du poids de l'ouvrant au dormant. Un dispositif de retour de porte en position fermée est en outre en général prévu, indépendamment ou en association avec ce dispositif d'articulation haut. A ce titre, le retour de porte à retour amorti pour le retour amorti de la porte connu en particulier de la demande de brevet européen N° EP 1 518 989 ou de la demande internationale de brevet N° WO 2007/135341 présente l'avantage de pouvoir cumuler les fonctions d'articulation et de retour amorti et peut lui aussi être pour l'essentiel caché dans le dormant de la porte.In the example illustrated here the device 1 constitutes a throttle for the opening 2, that is to say it allows to transmit most of the weight of the opening 2 to the frame 3, in the lower part of the opening and more specifically under opening. At least one other hinge device, not necessarily as the invention electromechanical stop, is then provided in the upper part of the door for the transmission of the rest of the weight of the opening to the frame. In addition, a door return device in the closed position is provided independently or in combination with this upper hinge device. As such, the return of amortized return door for the amortized return of the door known in particular the European patent application No. EP 1,518,989 or the international patent application No. WO 2007/135341 has the advantage of being able to combine the functions of articulation and return damped and can also be essentially hidden in the frame of the door.

Dans cette configuration crapaudine, le dispositif 1 ne constitue pas à proprement parler une charnière car l'axe de rotation est intégré dans l'ouvrant. Toutefois, il est tout à fait possible d'utiliser le dispositif selon l'invention de la même manière qu'une charnière à arrêt électromagnétique telle que celle connue de la demande internationale de brevet N° WO 96/18793 . Il n'est alors plus nécessaire d'utiliser une charnière ressort et une charnière amortisseur de retour pour la transmission du poids de l'ouvrant au dormant ; il est possible d'utiliser une charnière simple pour la transmission du reste du poids de l'ouvrant à l'encadrement et un retour de porte à retour amorti pour le retour amorti de la porte.In this configuration crapaudine, the device 1 does not strictly speaking a hinge because the axis of rotation is integrated in the opening. However, it is quite possible to use the device according to the invention in the same way as a hinge with electromagnetic shutdown such as that known from the international patent application No. WO 96/18793 . It is then no longer necessary to use a spring hinge and a return damper hinge for the transmission of the weight of the leaf to the frame; it is possible to use a simple hinge for the transmission of the rest of the weight of the opening to the frame and a return of cushioned return door for the amortized return of the door.

Par ailleurs, il est tout à fait possible d'utiliser le dispositif selon l'invention en partie haute de la porte, c'est-à-dire non pas comme pivot de rotation crapaudine, en bas, mais comme pivot de rotation haut, en association avec un pivot de sol classique pour la transmission du reste du poids de l'ouvrant au dormant. Un dispositif de fermeture de porte est en outre en général prévu, indépendamment ou en association avec ce pivot de sol.Furthermore, it is entirely possible to use the device according to the invention in the upper part of the door, that is to say, not as pivot rotation crapaudine, down, but as pivot of high rotation, in combination with a conventional floor pivot for the transmission of the rest of the weight of the opening to the frame. In general, a door closure device is provided independently or in association with this floor pivot.

Comme visible particulièrement sur la figure 2, tout le dispositif 1 à l'exception de la plaque 6 est dissimulé à l'intérieur de l'ouvrant 2 entre ses deux faces principales. Le dispositif est certes ici visible dans le bas du chant latéral 32, mais le carter 4 peut être dissimulé derrière une cache si nécessaire.As visible especially on the figure 2 , all the device 1 with the exception of the plate 6 is concealed inside the opening 2 between its two main faces. The device is certainly visible here at the bottom of the side edge 32, but the casing 4 can be hidden behind a cover if necessary.

La figure 2, ainsi que la figure 3, montrent que la partie mobile du dispositif 1 est reliée à l'ouvrant 2 par l'intermédiaire d'un socle 61 fixé à l'ouvrant 2 par exemple par des vis et détaillé ci-après.The figure 2 , as well as figure 3 , show that the mobile part of the device 1 is connected to the opening 2 through a base 61 fixed to the opening 2 for example by screws and detailed below.

L'ouvrant 2 est mobile par rapport à l'encadrement 3 selon un axe de rotation R, vertical, qui est confondu avec l'axe du carter 4.The opening 2 is movable relative to the frame 3 along an axis of rotation R, vertical, which coincides with the axis of the casing 4.

Des moyens pour le blocage de l'ouvrant 2 sont positionnés à l'intérieur du carter 4, à proximité de la plaque 6 : ces moyens comportent, comme dans la demande internationale de brevet N° WO 2008/017779 , d'une part des moyens de retenu électromécanique (ici plus précisément des moyens de retenu électromagnétiques comportant une ventouse électromagnétique et une contreplaque magnétique) et d'autre part des moyens de guidage comportant un fourreau tubulaire 13, fixé indirectement à l'ouvrant, dans lequel un cône 19 est monté mobile en translation, ledit fourreau tubulaire 13 comportant au moins deux cavités 15, 15' accueillant chacune une bille 16, 16' ainsi qu'une pièce d'arrêt 17, fixée indirectement à l'encadrement par l'intermédiaire du carter 4, présentant au moins deux alésages 18, 18' complémentaires.Means for locking the opening 2 are positioned inside the casing 4, close to the plate 6: these means comprise, as in the international patent application No. WO 2008/017779 on the one hand electromechanical retaining means (here more precisely electromagnetic retention means comprising an electromagnetic sucker and a magnetic counterplate) and, on the other hand, guiding means comprising a tubular sheath 13, fixed indirectly to the opening, in which a cone 19 is mounted to move in translation, said tubular sleeve 13 having at least two cavities 15, 15 'each accommodating a ball 16, 16' and a stop piece 17, fixed indirectly to the frame by the intermediate of the casing 4, having at least two complementary bores 18, 18 '.

Toutefois, selon l'invention, à la différence de la solution technique de la demande internationale N° WO 2008/017779 , lesdits moyens de guidage ne sont pas montés en rotation guidés à l'extérieur du carter 4, fixe, mais à l'intérieur de ce carter 4, fixe.However, according to the invention, unlike the technical solution of the international application No. WO 2008/017779 , said guide means are not mounted in rotation guided outside the casing 4, fixed, but inside this casing 4, fixed.

Cette rotation guidée est opérée ici à l'aide de deux roulements 40, 40' à billes interposés (comme visible sur les figures 9 et 10) :

  • pour l'un, le roulement 40, à l'extrémité supérieure dudit fourreau tubulaire 13 entre d'une part ledit fourreau tubulaire 13 et d'autre part ladite pièce d'arrêt 17 et ledit carter 4 et
  • pour l'autre, le roulement 40', à l'extrémité inférieure dudit fourreau tubulaire 13 entre d'une part ledit fourreau tubulaire 13 et d'autre part ladite pièce d'arrêt 17 et ledit carter 4.
This guided rotation is operated here using two bearings 40, 40 'interposed ball (as visible on the figures 9 and 10 ):
  • for one, the bearing 40, at the upper end of said tubular sheath 13 between said tubular sheath 13 and secondly said stop piece 17 and said casing 4 and
  • for the other, the bearing 40 'at the lower end of said tubular sheath 13 between said tubular sheath 13 on the one hand and said stop piece 17 and said casing 4 on the other.

Le dispositif 1 présente une hauteur hors-tout h1 de l'ordre de 150 mm et le diamètre du carter 4, d4 est de l'ordre de 40 mm.The device 1 has an overall height h 1 of the order of 150 mm and the diameter of the casing 4, d 4 is of the order of 40 mm.

Les moyens électromécaniques comportent une ventouse électromagnétique 12 située en partie basse dudit carter 4 à l'intérieur de ce dernier et sont alimentés en courant électrique grâce à des câbles 14 électriques qui passent au centre du carter 4 et sous ou dans la plaque 6. Ces câbles sont destinés à être reliés à une centrale de commande, non illustrée, chargée d'une manière connue de mettre la ventouse électromagnétique sous tension ou hors tension en fonction des critères retenus.The electromechanical means comprise an electromagnetic lock 12 located in the lower part of said casing 4 inside the latter and are supplied with electric current by means of electric cables 14 which pass to the center of the casing 4 and under or in the plate 6. cables are intended to be connected to a control unit, not shown, loaded in a known manner to turn the electromagnetic pad on or off depending on the criteria selected.

Le carter 4 renferme par ailleurs en partie haute le fourreau porte-billes 13, tubulaire, qui fait toutefois saillie hors du carter, en haut.The casing 4 also contains in the upper part the tubular carrying sleeve 13, tubular, which however protrudes out of the casing at the top.

Ce fourreau 13 présente, dans sa partie à l'intérieur du carter 4, deux trous 15, 15' coaxiaux et dont l'axe est perpendiculaire à l'axe de rotation R, dans chacun desquels une bille 16, 16' est positionnée, les diamètres des trous étant très légèrement supérieurs au diamètre des billes. Ces trous sont donc positionnés horizontalement à 180° l'un de l'autre. Chaque bille peut bouger selon l'axe des trous.This sleeve 13 has, in its part inside the casing 4, two holes 15, 15 'coaxial and whose axis is perpendicular to the axis of rotation R, in each of which a ball 16, 16' is positioned, the diameters of the holes being very slightly greater than the diameter of the balls. These holes are positioned horizontally 180 ° from each other. Each ball can move along the axis of the holes.

Toutefois, en direction centripète par rapport à l'axe R du centre du fourreau les billes 16, 16' sont retenue par le fourreau de blocage 17 tubulaire présentant deux alésages coaxiaux 18, 18', dont l'axe est perpendiculaire à l'axe de rotation R, positionnés aussi horizontalement à 180° l'un de l'autre et de diamètre inférieur au diamètre des billes 16, 16'.However, in a centripetal direction with respect to the axis R of the center of the sheath, the balls 16, 16 'are retained by the tubular locking sleeve 17 having two coaxial bores 18, 18' whose axis is perpendicular to the axis rotation R, also positioned horizontally at 180 ° from one another and of diameter less than the diameter of the balls 16, 16 '.

Lorsque la porte est fermée, la position relative des fourreaux 13, 17 est telle que les billes 16, 16' et les alésages 18, 18' du fourreau de blocage 17 sont décalés de l'angle d'ouverture et de blocage en position porte ouverte, ici de 90 °.When the door is closed, the relative position of the sleeves 13, 17 is such that the balls 16, 16 'and the bores 18, 18' of the locking sheath 17 are offset from the opening and locking angle in the door position. open, here 90 °.

Le fourreau porte-billes 13 comporte par ailleurs en son centre un cône 19, mobile axialement à l'intérieur de ce fourreau porte-billes. Ce cône présente à sa surface extérieure une cavité 20 annulaire, de forme complémentaire à celle des billes 16, 16'.The ball bearing sleeve 13 further comprises at its center a cone 19, axially movable inside this bearing sleeve. This cone has on its outer surface an annular cavity 20 of shape complementary to that of the balls 16, 16 '.

Un ressort 22 hélicoïdal prend appui à son extrémité basse contre la contre-plaque magnétique 21 et à son extrémité haute contre la face inférieure du fourreau porte-billes 13. Il est guidé en son centre par le cône 19.A helical spring 22 bears at its lower end against the magnetic counter-plate 21 and at its upper end against the underside of the ball-bearing sleeve 13. It is guided at its center by the cone 19.

Le cône 19 est relié à son extrémité basse à la contre-plaque magnétique 21 par l'intermédiaire d'une rotule 50, sans jeu, illustrée plus en détail en figures 5 à 8.The cone 19 is connected at its lower end to the magnetic counter-plate 21 via a ball 50 without play, illustrated in more detail in FIG. Figures 5 to 8 .

La rotule 50 comporte une extrémité sphérique 52, lisse, d'un diamètre extérieur d52 (d52 = 10 mm par exemple) et précédée d'un rétrécissement de section 51 de diamètre extérieur d51 ici de 0,5 fois le diamètre extérieur d52 de l'extrémité sphérique 52 (d51 = 5 mm par exemple).The ball 50 has a spherical end 52, smooth, with an outside diameter d 52 (d 52 = 10 mm for example) and preceded by a narrowing of section 51 of outer diameter d 51 by 0.5 times the outer diameter d 52 of the spherical end 52 (d 51 = 5 mm for example).

La rotule 50 comporte par ailleurs un écrou fendu 56 qui comporte sur sa face extérieure un alésage permettant de le visser sur la contre-plaque 21 qui dispose pour cela d'un trou borgne taraudé son centre. Cet écrou fendu 56 comporte une surface d'appui 53, lisse, sur laquelle vient reposer l'extrémité sphérique 52.The ball 50 also comprises a split nut 56 which has on its outer face a bore for screwing it on the plate against 21 which has for that a blind hole threaded its center. This split nut 56 has a bearing surface 53, smooth, on which comes to rest the spherical end 52.

Cette surface d'appui 53 comportant d'une part une arête proximale 54 au moins partiellement circulaire présentant un diamètre d54 (d54 = 9 mm par exemple) supérieur au diamètre extérieur d51 du rétrécissement de section 51 et inférieur au diamètre extérieur d52 de l'extrémité sphérique 52 et d'autre part une arête distale 55 au moins partiellement circulaire présentant un diamètre d55 (d55 = 10 mm par exemple) égal ou supérieur au diamètre extérieur d52 de l'extrémité sphérique 52. La surface d'appui 53 constitue ainsi la surface intérieure de l'écrou fendu qui est située entre l'arête proximale 54 et l'arête distale 55, l'arête proximale 54 présentant un diamètre d54 inférieur au diamètre d55 de l'arête distale 55.This bearing surface 53 having on the one hand an at least partially circular proximal edge 54 having a diameter of 54 (d 54 = 9 mm for example) greater than the outer diameter d 51 of the section narrowing 51 and smaller than the outer diameter d 52 of the spherical end 52 and, on the other hand, an at least partially circular distal edge 55 having a diameter d 55 (d 55 = 10 mm, for example ) or greater than the outer diameter d 52 of the spherical end 52. The bearing surface 53 thus constitutes the inner surface of the split nut which is located between the proximal edge 54 and the distal edge 55, the proximal edge 54 having a diameter d 54 smaller than the diameter d 55 of the distal edge 55.

Cette surface d'appui 53 est ici droite entre les deux arêtes 54, 55 (c'est-à-dire qu'elle forme un cône de circonvolution droite, mais fendu) et est ici orientée d'un angle de 45 ° par rapport à l'axe A passant par les centres des deux arêtes 54, 55 au moins partiellement circulaires.This bearing surface 53 is here right between the two edges 54, 55 (that is to say, it forms a cone of straight convolution, but split) and is here oriented at an angle of 45 ° relative to to the axis A passing through the centers of the two edges 54, 55 at least partially circular.

L'écrou fendu 56 (et ainsi aussi la surface d'appui 53) présente une largeur l56 (l56 = 16 mm par exemple) et une fente 57 d'une largeur l57 (l57 = 6 mm par exemple) égale ou supérieure au diamètre extérieur d51 du rétrécissement de section 51.The split nut 56 (and thus also the bearing surface 53) has a width l 56 ( 56 = 16 mm for example) and a slot 57 with a width l 57 ( 57 = 6 mm for example) equal or greater than the outside diameter d 51 of the section narrowing 51.

Comme visible sur les figures 5 à 7, respectivement, pour le montage de la rotule 60 :

  • l'écrou fendu 56 est introduit sur l'extrémité sphérique 52 en passant le rétrécissement de section 51 par la fente 57 ; l'extrémité sphérique 52 vient ainsi contre la surface d'appui 53 ; puis
  • l'axe du cône 19 est aligné avec l'axe de la contre-plaque 21 ; et enfin
  • l'écrou fendu 56 est vissé sur la contre-plaque 21.
As visible on Figures 5 to 7 , respectively, for mounting the ball 60:
  • the split nut 56 is introduced on the spherical end 52 by passing the section narrowing 51 through the slot 57; the spherical end 52 thus comes against the bearing surface 53; then
  • the axis of the cone 19 is aligned with the axis of the counterplate 21; and finally
  • the split nut 56 is screwed onto the plate 21.

Cette nature d'articulation permet un alignement parfait selon l'axe R de la contreplaque 21 par rapport à la ventouse 12 et évite une usure prématurée de l'un et/ou de l'autre.This nature of articulation allows a perfect alignment along the axis R of the counterplate 21 relative to the suction cup 12 and avoids premature wear of one and / or the other.

Le fonctionnement du dispositif 1 est, de préférence du type « sécurité positive » : Lorsqu'il y a rupture de courant d'alimentation des moyens électromagnétiques, le dispositif est libre et ne gêne en rien le passage par la porte, en particulier pour permettre l'évacuation des personnes.The operation of the device 1 is preferably of the "positive safety" type: When there is a break in the supply current of the electromagnetic means, the device is free and does not interfere with the passage through the door, in particular to allow the evacuation of people.

Armement du dispositifArmament of the device

Lorsque le dispositif est en position de sécurité (ouvrant libre d'être actionné) et que la porte est fermée, les billes 16, 16' ne sont pas alignées entre le fourreau porte-billes 13 et le fourreau de blocage 17 (situation non illustrée).When the device is in the safety position (open to be operated) and the door is closed, the balls 16, 16 'are not aligned between the ball bearing sleeve 13 and the locking sleeve 17 (situation not illustrated ).

Pour permettre le blocage de la porte en position ouverte, il convient alors d'alimenter la ventouse électromagnétique de la manière requise.To allow the door to be locked in the open position, it is then necessary to supply the electromagnetic lock in the required manner.

Lorsque la porte s'ouvre ensuite sous l'action d'une poussée manuelle, le fourreau porte-billes 13 tourne suivant l'axe de rotation R et va permettre d'aligner les billes avec les alésages présents dans le fourreau de blocage 17. Une fois cet alignement opéré, le ressort 22 pousse la contre plaque 21 vers la bas et cette dernière vient se « coller » sur la ventouse électromagnétique 12 entraînant ainsi le cône 19 solidaire de la contre-plaque 21. Par la même, les billes vont se loger dans les alésages 18, 18' du fourreau de blocage 17. Le dispositif est verrouillé.When the door then opens under the action of a manual push, the ball bearing sleeve 13 rotates about the axis of rotation R and will allow to align the balls with the bores present in the locking sleeve 17. Once this alignment has been made, the spring 22 pushes the plate 21 downwards and the latter "sticks" to the electromagnetic pad 12 thus causing the cone 19 secured to the plate 21. to be housed in the bores 18, 18 'of the locking sheath 17. The device is locked.

La porte est ouverte à 90° dans la configuration de la figure 9 et est bloquée dans cette position car la ventouse électromagnétique 12 exerce un effort de retenue sur la contre-plaque 21.The door is open at 90 ° in the configuration of the figure 9 and is locked in this position because the electromagnetic lock 12 exerts a retaining force on the counterplate 21.

Libération de l'ouvrantRelease of the opening

Deux cas sont possibles :

  • Cas 1 : Lorsqu'il y a rupture d'alimentation électrique, la ventouse électromagnétique 12 n'exerce plus d'effort de retenue sur la contre-plaque 21 et par conséquent, le couple induit du fourreau porte bille 13 sur les billes 16, 16' force celles-ci à rentrer dans la cavité 20 du cône 19 faisant du même coup remonter l'ensemble du cône 19 avec sa rotule 60 et sa contre-plaque 21.
    L'ouvrant est libéré de sa position de blocage pour revenir en position de sécurité, c'est-à-dire libre de tout mouvement. Si un moyen de retour exerce une force de retour sur l'ouvrant, par exemple par l'intermédiaire d'une charnière de retour ou par l'intermédiaire d'un retour de porte, alors l'ouvrant revient en position fermée.
  • Cas 2 : Le deuxième cas consiste à considérer qu'une force est appliquée contre l'ouvrant maintenu en position ouverte par la ventouse électromagnétique 12 alimentée en courant électrique. Le couple induit par l'ouvrant soumis à cette force de refermeture sur le dispositif, autrement dit du fourreau porte-billes 13 sur les billes 16, 16' force celles-ci à rentrer dans la cavité 20 par l'intermédiaire du cône 19 avec plus d'intensité (du fait de l'effort de retenue de la ventouse électromagnétique 12 toujours présent). Les billes 16, 16' par réaction du cône 19 font remonter celui-ci et viennent décoller la contre-plaque 21. La porte est alors ainsi libérée de sa position de blocage pour revenir en position de sécurité.
Two cases are possible:
  • Case 1 : When there is a break in the electrical supply, the electromagnetic lock 12 no longer exerts a retaining force on the counterplate 21 and consequently the induced torque of the ball bearing sheath 13 on the balls 16, 16 'forces them to enter the cavity 20 of the cone 19, at the same time raising the assembly of the cone 19 with its ball 60 and its counterplate 21.
    The opening is released from its locking position to return to the safety position, that is to say free of any movement. If a return means exerts a return force on the leaf, for example by means of a return hinge or through a door return, then the leaf returns to the closed position.
  • Case 2 : The second case consists in considering that a force is applied against the sash held in the open position by the electromagnetic pad 12 supplied with electric current. The torque induced by the sash subjected to this resealing force on the device, in other words the ball-bearing sleeve 13 on the balls 16, 16 'force them to enter the cavity 20 via the cone 19 with more intensity (due to the retaining force of the electromagnet 12 still present). The balls 16, 16 'by reaction of the cone 19 up the latter and come off the counter plate 21. The door is then released from its locking position to return to the safety position.

Lorsque la ventouse électromagnétique 12 n'est pas alimentée en courant électrique, l'ouvrant 2 est libre de tout mouvement, sous réserve de l'action de tout autre moyen (limitateur d'ouverture, butée, ...)When the electromagnetic lock 12 is not supplied with electric current, the opening 2 is free from any movement, subject to the action of any other means (opening limiter, stop, ...)

La figure 10 illustre ainsi la configuration dans laquelle l'ouvrant est libre de tourner et où il est ouvert à 90 °.The figure 10 illustrates the configuration in which the opening is free to rotate and where it is open at 90 °.

On voit bien sur cette figure que la contre-plaque 21 n'est plus retenue par la ventouse électromagnétique 12.This figure clearly shows that the counterplate 21 is no longer retained by the electromagnetic plunger 12.

Le mouvement de rotation de l'ouvrant s'opère par rotation des billes 16, 16' autour de la cavité 20 annulaire du cône 19 puisque le fourreau porte-billes 13 est solidaire de l'ouvrant 2.The rotational movement of the opening is effected by rotation of the balls 16, 16 'around the annular cavity 20 of the cone 19 since the bearing sleeve 13 is integral with the opening 2.

Réglage de la position de retenueAdjustment of the holding position

Dans une variante toute particulière de l'invention, ledit fourreau tubulaire 13 est fixé à l'ouvrant 2 par l'intermédiaire d'un système de réglage d'ouverture 60.In a very particular variant of the invention, said tubular sheath 13 is fixed to the opening 2 by means of an opening adjustment system 60.

Comme visible en figure 11, pour le montage de l'ouvrant 2 sur le dispositif 1, il est alors proposé de fixer au préalable un socle 61 à l'ouvrant 2. Ce socle présente un trou circulaire pour accueillir la partie supérieure du fourreau 13, celle qui fait saillie hors du carter 4.As visible in figure 11 , for the mounting of the opening 2 on the device 1, it is then proposed to fix beforehand a base 61 to the opening 2. This base has a circular hole to accommodate the upper part of the sleeve 13, the one that protrudes out of the housing 4.

Le système de réglage comporte d'une part une goupille 62 traversant transversalement le fourreau tubulaire 13 et d'autre part un socle 61 fixé à l'ouvrant 2, par exemple par des vis.The adjustment system comprises firstly a pin 62 traversing transversely the tubular sheath 13 and secondly a base 61 fixed to the opening 2, for example by screws.

Il est possible de procéder à un réglage de la position relative de la porte par rapport au dispositif de blocage et en conséquence de régler l'angle d'accrochage de la porte. Le socle 61, fixé solidairement à la porte par les vis, est inséré sur la partie cylindrique en partie supérieure du fourreau 13. Sur ce fourreau 13 un manchon 63 est monté via une goupille 62. Le jeu entre d'une part le socle 61 mobile autour de l'axe R et d'autre part le manchon 63 fixé rigidement au fourreau 13 est tel qu'il est possible au socle 61 de pivoter autour du fourreau 13 sur une plage angulaire d'amplitude ∼10°, limité par le manchon 61. Le socle 61 comporte deux trous taraudés, disposés de part et d'autre de l'axe de rotation, permettant d'accueillir deux vis de réglage 64.It is possible to adjust the relative position of the door relative to the locking device and consequently to adjust the hooking angle of the door. The base 61, fastened integrally to the door by the screws, is inserted on the cylindrical part in the upper part of the sleeve 13. On this sleeve 13 a sleeve 63 is mounted via a pin 62. The clearance between on the one hand the base 61 mobile about the axis R and secondly the sleeve 63 fixed rigidly to the sleeve 13 is such that it is possible for the base 61 to pivot about the sleeve 13 over an angular range of amplitude ~10 °, limited by the sleeve 61. The base 61 has two threaded holes, disposed on either side of the axis of rotation, for accommodating two adjusting screws 64.

Lorsque les vis 64 sont serrées, elles viennent en contact sur le manchon 63, immobilisant ainsi en rotation le socle 61 par rapport au manchon 63 et donc au dispositif 1.When the screws 64 are tightened, they come into contact with the sleeve 63, thus immobilizing in rotation the base 61 with respect to the sleeve 63 and thus to the device 1.

En modifiant la position des vis 64 dans le socle 61 (en vissant ou en dévissant), la position du socle par rapport au dispositif de blocage s'en trouve modifiée. Par ce fait, il est possible de régler la position d'arrêt de la porte autour du réglage usine à +/-5°, comme visible en figures 12 et 13.By changing the position of the screws 64 in the base 61 (by screwing or unscrewing), the position of the base relative to the blocking device is changed. As a result, it is possible to set the door stop position around the factory setting to +/- 5 °, as shown in Figures 12 and 13 .

La présente invention est décrite dans ce qui précède à titre d'exemple. Il est entendu que l'homme du métier est à même de réaliser différentes variantes de l'invention sans pour autant sortir du cadre du brevet tel que défini par les revendications.The present invention is described in the foregoing by way of example. It is understood that the skilled person is able to achieve different variants of the invention without departing from the scope of the patent as defined by the claims.
