Abstract

The door-closer (20) has a mechanical connection system interposed between an electromagnetic retaining part and a hydraulic damping return part. The system has cams (10, 10') that are provided with contact areas and hook areas and are movable in rotation around corresponding axes. The axes of the cams are located on an intermediate case (8) that is movable in translation by screwing/unscrewing along a longitudinal central axis with respect to the retaining part and/or the return part.

Description

La présente invention se rapporte au domaine des ferme-portes à retenue électromagnétique.The present invention relates to the field of door closers with electromagnetic retention.

Un ferme-porte à retenue électromagnétique et à amortissement hydraulique est connu de la demande de brevet européen N° EP 1 375 807 .An electromagnetic retention and hydraulic damping door closer is known from European Patent Application No. EP 1 375 807 .

Ce ferme-porte comporte une partie à retenue électromagnétique comportant un moyen de retenue électromagnétique et une partie de rappel comportant un moyen de rappel et notamment un moyen de rappel à amortissement hydraulique ainsi qu'un système de liaison mécanique entre ces deux parties. Ce système de liaison mécanique comporte une cloche, c'est-à-dire un cône ouvert à ces deux extrémités longitudinales, ainsi qu'une pluralité de billes logées dans des logements d'un piston liée mécaniquement à un moyen de rappel.This door closer comprises an electromagnetically held portion comprising an electromagnetic retaining means and a return portion comprising a return means and in particular a hydraulic damping return means and a mechanical connection system between these two parts. This mechanical connection system comprises a bell, that is to say a cone open at both longitudinal ends, and a plurality of balls housed in housings of a piston mechanically linked to a biasing means.

La présente invention concerne plus particulièrement un ferme-porte à retenue électromagnétique comportant une partie à retenue électromagnétique et une partie de rappel ainsi qu'un système de liaison mécanique comportant au moins une came, cette came présentant une zone de contact et une zone en crochet et cette came étant mobile en rotation autour d'un axe.The present invention more particularly relates to an electromagnetic retainer with an electromagnetic retention portion and a return portion and a mechanical connection system comprising at least one cam, this cam having a contact zone and a hook zone. and this cam being rotatable about an axis.

Un tel ferme-porte est connu de la demande de brevet britannique N° GB 2 188 674 . Dans ce dispositif, une came est mobile autour d'un axe fixé sur un manchon qui se déplace dans un carter en fonction de certains mouvements d'ouverture et de fermeture de la porte tout en étant en permanence soumis à l'effet d'un ressort en compression qui prend appui sur ce manchon.Such a door closer is known from British Patent Application No. GB 2,188,674 . In this device, a cam is movable about an axis fixed on a sleeve which moves in a housing according to certain movements of opening and closing of the door while being permanently subjected to the effect of a compression spring that bears on this sleeve.

Un tel ferme-porte est aussi connu du brevet américain N° US 4,506,407 . Dans ce dispositif, deux cames sont mobiles en rotation chacune autour d'un axe qui est fixé au carter qui accueille le moyen de retenue électromagnétique.Such a door closer is also known from US Patent No. US 4,506,407 . In this device, two cams are rotatable each around an axis which is fixed to the casing which houses the electromagnetic retention means.

Un tel ferme-porte est en outre connu de la demande de brevet allemand N° DE 102005040659 . Dans ce dispositif, chaque came est mobile en rotation autour d'un axe. Les cames du ferme-porte présenté dans ce document lorsque le ferme-porte est considéré longitudinalement (c'est-à-dire en coupe selon l'axe longitudinal central du ferme-porte), ont ceci de particulier : l'axe de rotation des cames est positionné à une extrémité des cames ; plus précisément, la zone de contact et la zone en crochet sont situées du même côté de l'axe de rotation des cames : du côté de la partie de rappel.Such door closer is also known from the German patent application No. DE 102005040659 . In this device, each cam is rotatable about an axis. The door closer cams presented in this document when the door closer is considered longitudinally (that is to say in section along the central longitudinal axis of the door closer), have this particular feature: the axis of rotation cams is positioned at a end of the cams; more precisely, the contact zone and the hook zone are located on the same side of the axis of rotation of the cams: on the side of the return portion.

Ainsi, dans ce ferme-porte, il y a selon l'axe longitudinal du ferme-porte une succession : partie à retenue électromagnétique / axe de rotation des cames / zone de contact / zone en crochet / chariot mobile dans une glissière qui est lié par un bras de liaison à un moyen de rappel ; ce chariot mobile appartient ainsi à la partie de rappel.Thus, in this door closer, there is along the longitudinal axis of the door closer a succession: part with electromagnetic retention / axis of rotation of the cams / contact zone / hook zone / moving carriage in a slide which is bound by a link arm to a return means; this mobile carriage thus belongs to the return portion.

Un inconvénient majeur du dispositif présenté dans ce document DE 102005040659 est constitué par le fait qu'il est difficile de le dissimuler dans un dormant et a fortiori dans un ouvrant en raison de son volume et en raison de la coopération chariot mobile/bras de liaison.A major drawback of the device presented in this document DE 102005040659 is constituted by the fact that it is difficult to hide it in a frame and a fortiori in an opening due to its volume and because of the mobile carriage / link arm cooperation.

En particulier au regard des efforts en jeux, les cames doivent être suffisamment longues et leurs axes de rotation suffisamment écartés de l'axe longitudinal central du ferme-porte. Il n'est pas envisageable de les raccourcir, sauf à écarter leurs axes de rotation de l'axe longitudinal central : le ferme-porte serait alors plus court, mais plus large.In particular, with regard to the forces involved, the cams must be sufficiently long and their axes of rotation sufficiently spaced from the central longitudinal axis of the door closer. It is not conceivable to shorten them, except to remove their axes of rotation from the central longitudinal axis: the closer would be shorter, but wider.

Par ailleurs, il arrive fréquemment que la position dans laquelle il est souhaité que la porte soit maintenue ouverte ne soit pas une position standard, comme 90 ° ou 180 °, mais soit 85 ° ou 95 °, ou encore 170 °. Les dispositifs de l'art antérieur ne permettent pas de régler facilement, après l'installation du ferme-porte, l'angle de maintien en position porte ouverte.Furthermore, it frequently happens that the position in which it is desired that the door is kept open is not a standard position, such as 90 ° or 180 °, but is 85 ° or 95 °, or 170 °. The devices of the prior art do not allow to easily adjust, after installation of the door closer, the holding angle in the open door position.

En outre, il apparaît que de nombreux ferme-porte de l'art antérieur ne présentent par la fiabilité requise (au moins 25 000 cycles en déclanchement électrique et 25 000 cycles en déclanchement forcé), en raison particulièrement du nombre de pièces en mouvement les unes par rapport aux autres lors de l'ouverture et de la fermeture de la porte.In addition, it appears that many door closers of the prior art do not have the required reliability (at least 25,000 cycles in electrical release and 25,000 cycles in forced release), particularly due to the number of moving parts the with each other when opening and closing the door.

Le but de l'invention est de pallier les inconvénients de l'art antérieur en proposant un ferme-porte compact, qui puisse être facilement dissimulé dans un dormant ou un ouvrant, ou qui puisse être conçu comme pivot de sol, tout en étant suffisamment fiable et dont l'angle de maintien en position porte ouverte soit réglable facilement.The object of the invention is to overcome the disadvantages of the prior art by providing a compact door closer, which can be easily concealed in a frame or an opening, or which can be designed as a floor pivot, while being sufficiently reliable and whose holding angle in the open door position is easily adjustable.

La présente invention se rapporte ainsi dans son acception la plus large à un ferme-porte à retenue électromagnétique selon la revendication 1. Les revendications dépendantes présentent des solutions plus particulières.The present invention thus relates in its broadest sense to an electromagnetic restraining door closer according to claim 1. The dependent claims present more particular solutions.

Le ferme-porte à retenue électromagnétique selon l'invention comporte une partie à retenue électromagnétique et une partie de rappel ainsi qu'un système de liaison mécanique comportant au moins une came, cette came présentant une zone de contact et une zone en crochet et étant mobile en rotation autour d'un axe et la came (et de préférence chaque came) est montée sur un carter intermédiaire qui est mobile en translation selon l'axe longitudinal par vissage/dévissage par rapport à ladite partie à retenue électromagnétique et/ou ladite partie de rappel. Ainsi, il est possible de modifier la position longitudinale de l'axe (ou des axes) de la (ou des) came(s) qui est (ou qui sont) monté(s) sur ce carter intermédiaire par rapport à ladite partie à retenue électromagnétique et/ou ladite partie de rappel. Ce réglage (ce vissage/dévissage) est opéré est dehors de tout mouvement à l'intérieur du ferme-porte pour le rappel de la porte.The electromagnetic retainer according to the invention comprises an electromagnetic retaining part and a return part as well as a mechanical connection system comprising at least one cam, this cam having a contact zone and a hook zone and being mobile in rotation about an axis and the cam (and preferably each cam) is mounted on an intermediate casing which is movable in translation along the longitudinal axis by screwing / unscrewing with respect to said electromagnetic retaining portion and / or said recall party. Thus, it is possible to modify the longitudinal position of the axis (or axes) of the (or) cam (s) which is (or are) mounted (s) on this intermediate casing relative to said portion to electromagnetic restraint and / or said return portion. This adjustment (this screwing / unscrewing) is operated outside of any movement inside the door closer for the return door.

La came (et de préférence chaque came) étant considérée longitudinalement (c'est-à-dire en coupe selon l'axe longitudinal du ferme-porte), l'axe de rotation de la came (et de préférence chaque came) est, de préférence, positionné entre la zone de contact et la zone en crochet.The cam (and preferably each cam) being considered longitudinally (that is to say in section along the longitudinal axis of the door closer), the axis of rotation of the cam (and preferably each cam) is, preferably, positioned between the contact zone and the hook zone.

La came (et de préférence chaque came) présente ainsi, de préférence, en coupe longitudinale une forme globale de haricot avec une zone de contact à une extrémité longitudinale, une zone en crochet à une autre extrémité longitudinale et la came (et de préférence chaque came) est mobile autour d'un axe de rotation qui est situé entre ces deux zones.The cam (and preferably each cam) thus preferably has, in longitudinal section, an overall shape of beans with a contact zone at one longitudinal end, a hook zone at another longitudinal end and the cam (and preferably each cam) is movable around an axis of rotation which is located between these two zones.

Dans une variante préférée de l'invention, l'axe de la came (et de préférence chaque came) est positionné sensiblement à égale distance des deux extrémités longitudinales de la came, ou l'axe de la came (et de préférence chaque came) est positionné plus près de l'extrémité longitudinale de la came (ou de chaque came) qui comporte la zone de contact que de l'extrémité longitudinale de la came qui comporte la zone en crochet.In a preferred variant of the invention, the axis of the cam (and preferably each cam) is positioned substantially equidistant from the two longitudinal ends of the cam, or the axis of the cam (and preferably each cam) is positioned closer to the longitudinal end of the cam (or each cam) which has the contact zone than the longitudinal end of the cam which has the hook zone.

Par ailleurs, de préférence, ladite came (et de préférence encore chaque came) étant considérée longitudinalement, la surface de la zone de contact et/ou la surface de la zone en crochet est arrondie (c'est-à-dire que dans cette et/ou ces zone(s), il n'y a pas de surface plane qui serait parallèle à l'axe de rotation de la came ; la surface est courbe avec au moins un, voir plusieurs, rayon(s) de courbure selon un axe parallèle à l'axe de rotation de la came).Furthermore, preferably, said cam (and preferably still each cam) being considered longitudinally, the surface of the contact zone and / or the surface of the hook zone is rounded (that is to say that in this and / or these zone (s), there is no plane surface which would be parallel to the axis of rotation of the cam, the surface is curved with at least one, or more, radius (s) of curvature according to an axis parallel to the axis of rotation of the cam).

Selon l'invention, les cames sont, de préférence, au nombre de deux, voire quatre. Elles sont de préférence en nombre pair.According to the invention, the cams are preferably two or even four. They are preferably even in number.

Dans une autre variante particulière, indépendamment du fait que l'axe de rotation de la (ou des) came(s) soit ou non positionné entre la zone de contact et la zone en crochet, il est préféré que la zone en crochet coopère avec une zone complémentaire qui est liée mécaniquement à un moyen de retenue électromagnétique appartenant à la partie à retenue électromagnétique ; la zone de contact coopère alors avec un élément de rappel appartenant à la partie de rappel ; la zone de contact coopère alors, de préférence, avec une zone complémentaire qui est située sur un doigt qui est lié mécaniquement à un moyen de rappel.In another particular variant, regardless of whether or not the axis of rotation of the cam (s) is positioned between the contact zone and the hook zone, it is preferred that the hook zone cooperate with a complementary zone which is mechanically connected to an electromagnetic retaining means belonging to the electromagnetic retaining part; the contact zone then cooperates with a return element belonging to the return portion; the contact zone then preferably cooperates with a complementary zone which is located on a finger which is mechanically linked to a return means.

Dans cette variante particulière, les zones en crochet de deux cames coopèrent, de préférence, avec une tige en forme de T, ladite tige étant de préférence montée en rotation selon un axe qui est orienté dans l'espace perpendiculairement aux axes des cames (cet axe n'est toutefois pas sécant avec les axes des cames), afin d'offrir un degré de liberté à la position du tronc de la forme en T autour de cet axe.In this particular variant, the hook zones of two cams preferably cooperate with a T-shaped rod, said rod preferably being mounted in rotation along an axis which is oriented in the space perpendicular to the axes of the cams (this axis is not secant with the axes of the cams), to provide a degree of freedom to the position of the trunk of the T-shape around this axis.

La présente invention se rapporte également à une porte dans l'ouvrant ou le dormant de laquelle est positionné un ferme-porte selon l'invention. Par « dormant » il faut comprendre ici toute l'ossature de la porte, qu'elle soit en menuiserie ou en maçonnerie.The present invention also relates to a door in the opening or the frame of which is positioned a door closer according to the invention. By "sleeping" it is necessary to understand here all the frame of the door, that it is in carpentry or in masonry.

Pour cette porte, ledit ferme-porte comprend un boîtier dans lequel est monté au moins un arbre d'entraînement mobile en rotation faisant saillie à l'extérieur dudit boîtier, ledit arbre d'entraînement étant relié par cette partie faisant saillie respectivement audit dormant ou audit ouvrant de la porte.For this door, said door closer comprises a housing in which is mounted at least one rotatable movable drive shaft protruding outside said housing, said drive shaft being connected by this protruding portion respectively to said frame or opening audit of the door.

Ce boîtier est alors, de préférence, caché, pour l'essentiel, à l'intérieur dudit ouvrant ou dudit dormant (les moyens qui permettent de visser/dévisser le carter intermédiaire doivent malgré tout être préhensibles).This housing is then preferably concealed, for the most part, inside said opening or said frame (the means which make it possible to screw / unscrew the intermediate casing must nevertheless be prehensile).

Avantageusement, le ferme-porte selon l'invention est très compact, avec une largeur faible et une longueur faible qui sont telles qu'il peut être facilement caché dans le dormant ou dans l'ouvrant d'une porte, tout en étant très fiable pour chaque utilisation (blocage/déblocage de la porte) et très fiable dans le temps (conservation du blocage).Advantageously, the door closer according to the invention is very compact, with a small width and a small length that are such that it can be easily hidden in the frame or in the opening of a door, while being very reliable. for each use (locking / unlocking the door) and very reliable over time (blocking retention).

Il n'y a pas de possibilité de fuite qui engendrerait une fermeture intempestive de la porte retenue et la porte est retenue avec la même force même après plusieurs milliers de refermeture.There is no possibility of leakage that would cause an inadvertent closing of the restrained door and the door is retained with the same force even after several thousand reclosure.

Avantageusement également, il est possible de régler facilement l'angle (par exemple autour de 90 ° ou de 180 °), ainsi que la force de retenue de la porte.Advantageously also, it is possible to easily adjust the angle (for example around 90 ° or 180 °), as well as the retention force of the door.

Avantageusement en outre, du fait que l'axe (ou les axes) de la (ou des) came(s) est (ou sont) monté(s) sur un carter intermédiaire qui est mobile en translation par vissage/dévissage uniquement d'une bague de réglage, le réglage de l'angle de maintien en position porte ouverte est alors très facile à réaliser, tout en étant très fiable dans le temps.Advantageously further, because the axis (or axes) of the (or) cam (s) is (or are) mounted (s) on an intermediate casing which is movable in translation by screwing / unscrewing only of a setting ring, the setting of the holding angle in the open door position is then very easy to achieve, while being very reliable over time.

Le nombre de pièces en mouvement les unes par rapport aux autres lors des mouvements d'ouverture ou de fermeture de la porte est limité afin d'augmenter la fiabilité du ferme-porte et permettre de passer le nombre de cycles requis.The number of moving parts relative to each other during the opening or closing movements of the door is limited to increase the reliability of the door closer and to pass the number of cycles required.

Avantageusement enfin, en fonctionnement (c'est-à-dire après le montage du ferme-porte et le réglage nécessaire à son utilisation), la partie à retenue électromagnétique est fixe par rapport à la partie de rappel et par rapport au carter intermédiaire qui est interposé entre ces deux parties afin d'améliorer, là encore, la fiabilité.Advantageously finally, in operation (that is to say after the mounting of the door closer and the adjustment necessary for its use), the electromagnetic retention portion is fixed relative to the return portion and relative to the intermediate housing which is interposed between these two parties to improve, again, the reliability.

La présente invention sera mieux comprise à la lecture de la description détaillée ci-après d'un exemple de réalisation non limitatif et des figures ci-jointes :

  • La figure 1 illustre une vue de face arrière d'un exemple de réalisation d'un ferme-porte selon l'invention ;

  • La figure 5 illustre une vue de dessus du ferme-porte de la figure 1, avec le carter intermédiaire et la partie à retenue électromagnétique tournés d'environ un quart de tour par rapport à la partie de rappel.
The present invention will be better understood on reading the detailed description below of a nonlimiting exemplary embodiment and the attached figures:
  • The figure 1 illustrates a rear view of an embodiment of a door closer according to the invention;
  • The figure 2 illustrates a sectional view according to EE of the figure 1 when the door closer according to the invention is in the unlocked position, the door being closed;

  • The figure 5 illustrates a top view of the door closer of the figure 1 , with the intermediate casing and the electromagnetically held portion turned about a quarter of a turn with respect to the return portion.

Il est précisé que dans ces figures les éléments de coupe en arrière plan ne sont pas toujours représentés mais que dans ces figures et d'une figure à l'autre (sauf pour la figure 5 qui est à une échelle plus petite) les proportions entre les divers éléments représentés sont respectées et, afin d'en faciliter la lecture.It is specified that in these figures the cutting elements in the background are not always represented but that in these figures and from one figure to another (except for the figure 5 which is on a smaller scale) the proportions between the various elements represented are respected and, in order to make them easier to read.

La figure 1 illustre un ferme-porte 20 à retenue électromagnétique et à amortissement hydraulique et plus précisément montre la partie arrière d'un tel ferme-porte.The figure 1 illustrates a door closer 20 with electromagnetic retention and hydraulic damping and more precisely shows the rear part of such a door closer.

Comme visible sur cette figure 1, le ferme-porte 20 comporte une partie à retenue électromagnétique A et une partie de rappel B à amortissement hydraulique.As visible on this figure 1 , the door closer 20 comprises an electromagnetically restrained portion A and a hydraulic damping return portion B.

La figure 1 n'illustre pas la partie avant du ferme-porte, dans laquelle est opéré le lien mécanique entre la partie de rappel B et l'ouvrant ou le dormant auquel cette partie est reliée. Ce lien mécanique peut être identique à celui connu de la demande de brevet européen N° EP 1 375 807 .The figure 1 does not illustrate the front part of the door closer, in which is made the mechanical connection between the return part B and the opening or the frame to which this part is connected. This mechanical link may be identical to that known from the European patent application No. EP 1 375 807 .

Dans le cadre de la présente invention, comme pour ce document antérieur, le ferme-porte est un dispositif permettant un maintien de la porte dans une zone autour de 90° d'ouverture. L'arrêt en position ouverte de la porte est réalisé par un système électromécanique et plus précisément par un système électromagnétique. Ce mécanisme verrouille le mouvement du dispositif de fermeture de porte en lui interdisant d'agir. La zone d'arrêt « position ouverte » est réglable angulairement autour de 90°.In the context of the present invention, as for this prior document, the door closer is a device for holding the door in an area around 90 ° opening. The stop in the open position of the door is achieved by an electromechanical system and more specifically by an electromagnetic system. This mechanism locks the movement of the door closing device by prohibiting it from acting. The "open position" stop zone is adjustable angularly around 90 °.

De même, la fermeture de la porte peut être provoquée : soit par déverrouillage de l'appareil, via une commande électrique (et dans ce cas précis une coupure électrique), soit par forçage mécanique sur la porte elle-même. Dans le cas d'un forçage, le mécanisme se déverrouille alors de lui-même.Similarly, the closing of the door can be caused: either by unlocking the device, via an electrical control (and in this case an electrical cut), or by mechanical forcing on the door itself. In the case of forcing, the mechanism then unlocks itself.

Les figures 2 et 3 ci-jointes illustrent chacune une vue en coupe selon EE de la figure 1, c'est-à-dire selon l'axe longitudinal central X du ferme-porte ; la différence entre ces figures est expliquée plus loin.The Figures 2 and 3 attached hereto each illustrate a sectional view according to EE of the figure 1 that is to say along the central longitudinal axis X of the door closer; the difference between these figures is explained below.

Un bouchon 5 cylindrique et tubulaire vient fermer l'extrémité d'un carter principal 21 qui accueille la partie de rappel B à amortissement hydraulique. Ce bouchon 5 est vissé à son bord extérieur sur ce carter et comporte en son centre un trou pour le passage d'un doigt 1. Le doigt 1 est assemblé (mécaniquement solidaire) avec un ressort de rappel 4 en compression qui est en appui à l'une de ses extrémités sur le bouchon 5 et à l'autre extrémité sur une rondelle 3 et un circlip 2 liés au piston de la partie de rappel B. Le doigt 1 est mobile par rapport au bouchon 5.A cylindrical and tubular plug 5 closes the end of a main casing 21 which receives the return portion B with hydraulic damping. This cap 5 is screwed to its outer edge on this housing and has in its center a hole for the passage of a finger 1. The finger 1 is assembled (mechanically secured) with a compression spring 4 which is in support of one of its ends on the plug 5 and at the other end on a washer 3 and a circlip 2 connected to the piston of the return portion B. The finger 1 is movable relative to the plug 5.

Un joint d'étanchéité 7 annulaire empêche toute fuite hydraulique en dehors de la partie de rappel B entre le bouchon 5 et le doigt 1.An annular seal 7 prevents hydraulic leakage outside the return portion B between the plug 5 and the finger 1.

Un carter intermédiaire 8 est accroché au bouchon 5 via une bague de réglage 6 qui est fixée sur la partie extérieure du bouchon 5 et qui présente une partie filetée intérieure sur laquelle le carter intermédiaire 8 est vissé.An intermediate casing 8 is hooked to the cap 5 via an adjusting ring 6 which is fixed on the outer part of the plug 5 and which has an inner threaded portion on which the intermediate casing 8 is screwed.

La partie à retenue électromagnétique A comporte une ventouse 16 électromagnétique, alimentée en courant via un câble d'alimentation 17. Cette ventouse coopère avec une contreplaque 14 située en vis-à-vis.The electromagnetic retention portion A comprises an electromagnetic suction cup 16, supplied with current via a power cable 17. This suction cup cooperates with a counterplate 14 located opposite.

La ventouse 16 est vissée sur un carter mécanique 15 formé d'un cylindre tubulaire. Ce carter mécanique 15 est lui-même vissé sur le carter intermédiaire 8.The suction cup 16 is screwed onto a mechanical casing 15 formed of a tubular cylinder. This mechanical casing 15 is itself screwed onto the intermediate casing 8.

Les trois carters : le carter principal 21, le carter intermédiaire 8 et le carter mécanique 15 sont ainsi positionnés l'un à la suite de l'autre, dans cet ordre, avec leurs axes centraux respectifs situés dans l'espace selon le même axe : l'axe longitudinal central du ferme-porte. Ces carters sont immobiles les uns par rapport aux autres pendant le mouvement d'ouverture/fermeture de la porte.The three housings: the main housing 21, the intermediate housing 8 and the mechanical housing 15 are thus positioned one after the other, in this order, with their respective central axes located in the space along the same axis : the central longitudinal axis of the door closer. These housings are stationary relative to each other during the opening / closing movement of the door.

Le carter intermédiaire 8 est mobile en translation par vissage/dévissage selon l'axe longitudinal par rapport à ladite partie à retenue électromagnétique A et/ou ladite partie de rappel B.The intermediate casing 8 is movable in translation by screwing / unscrewing along the longitudinal axis with respect to said electromagnetic retention portion A and / or said return portion B.

Le carter intermédiaire 8 peut présenter par ailleurs sur son pourtour des moyens qui permettent de visser/dévisser le carter intermédiaire : une couronne ou au moins un plot qui fait saillie entre le carter principal 21 et le carter mécanique 15.The intermediate casing 8 may furthermore have on its periphery means which make it possible to screw / unscrew the intermediate casing: a crown or at least one stud which projects between the main casing 21 and the mechanical casing 15.

Pour permettre ce mouvement de translation sans modification de la position angulaire du carter intermédiaire 8 par rapport à l'autre ou aux autres parties A et/ou B, le ferme-porte selon l'invention comporte de préférence au moins une bague de réglage 6 qui est interposée entre le carter intermédiaire 8 et une des parties A et/ou B et cette bague de réglage 6 présente un double filetage gauche/droit, dans deux sens opposés.To allow this translational movement without changing the angular position of the intermediate casing 8 relative to the other or the other parts A and / or B, the door closer according to the invention preferably comprises at least one adjustment ring 6 which is interposed between the intermediate casing 8 and one of the parts A and / or B and this adjusting ring 6 has a double left / right thread, in two opposite directions.

Cette bague de réglage 6 peut ainsi, comme illustrée, être vissée par un premier filetage sur le carter principal 21 accueillant la partie de rappel B et par un second filetage, inverse du premier, au carter intermédiaire 8, pour permettre de régler la position relative axiale du carter intermédiaire 8 par rapport à la partie de rappel B ; cette bague de réglage 6 comporte, de préférence, sur son pourtour des moyens facilitant sa préhension, comme par exemple une couronne ou au moins un plot.This adjustment ring 6 can thus, as illustrated, be screwed by a first thread on the main casing 21 accommodating the return portion B and by a second thread, inverse of the first, to the intermediate casing 8, to allow the relative position to be adjusted. axial of the intermediate casing 8 relative to the return portion B; this adjusting ring 6 preferably comprises on its periphery means facilitating its gripping, such as a crown or at least one stud.

Les figures 2 et 3 montrent par ailleurs qu'un système de liaison mécanique comportant deux cames 10, 10' est interposé entre la partie à retenue électromagnétique A et la partie de rappel B.The Figures 2 and 3 show also that a mechanical connection system comprising two cams 10, 10 'is interposed between the electromagnetic retention portion A and the return portion B.

Ces deux cames 10, 10' sont montées chacune respectivement sur un arbre 9, 9' cylindrique qui est fixé sur le carter intermédiaire 8. Les cames 10, 10' sont ainsi chacune mobiles en rotation par rapport au carter intermédiaire 8 par rotation autour des arbres 9, 9'. Chaque arbre 9, 9'est orienté respectivement selon un axe Y, Y' qui est fixe par rapport au carter intermédiaire 8.These two cams 10, 10 'are each mounted respectively on a cylindrical shaft 9, 9' which is fixed on the intermediate casing 8. The cams 10, 10 'are thus each movable in rotation relative to the intermediate casing 8 by rotation around the trees 9, 9 '. Each shaft 9, 9 is oriented respectively along an axis Y, Y 'which is fixed relative to the intermediate casing 8.

Chaque axe Y, Y' est en permanence orienté dans l'espace selon une direction qui est perpendiculaire à l'axe longitudinal central X du ferme-porte.Each Y, Y 'axis is permanently oriented in the space in a direction which is perpendicular to the central longitudinal axis X of the door closer.

Chaque came 10, 10' présente une zone de contact C, C' et une zone en crochet D, D'Each cam 10, 10 'has a contact zone C, C' and a hook zone D, D '

Les cames 10, 10' étant considérée longitudinalement, l'axe Y, Y' de chaque came est positionné entre la zone de contact C, C' et la zone en crochet D, D'.The cams 10, 10 'being considered longitudinally, the Y axis, Y' of each cam is positioned between the contact zone C, C 'and the hook zone D, D'.

Chaque came 10, 10' présente ainsi en coupe longitudinale une forme globale de haricot avec une zone de contact C, C' à une extrémité longitudinale (l'extrémité gauche sur les figures 2 et 3), une zone en crochet D, D' à une autre extrémité longitudinale (l'extrémité droite sur les figures 2 et 3) et chaque came est mobile autour d'un axe Y, Y' de rotation qui est situé entre ces deux zones.Each cam 10, 10 'thus has, in longitudinal section, an overall shape of beans with a contact zone C, C' at one longitudinal end (the left end on the Figures 2 and 3 ), a hook zone D, D 'at another longitudinal end (the right end on the Figures 2 and 3 ) and each cam is movable about a Y axis, Y 'of rotation which is located between these two zones.

Comme visible sur les figures 2 et 3, l'axe Y, Y' de chaque came 10, 10' est positionné plus près de l'extrémité longitudinale de chaque came 10, 10' qui comporte la zone de contact C, C' (à gauche des axes Y, Y' sur les figures) que de l'extrémité longitudinale de la came 10, 10' qui comporte la zone en crochet D, D' (à droite des axes Y, Y' sur les figures). Ainsi, le moment de force est plus grand pour la fonction crochet mise en oeuvre par les zones en crochet D, D' que pour la fonction contact mise en oeuvre par les zones de contact C, C'.As visible on Figures 2 and 3 the Y axis, Y 'of each cam 10, 10' is positioned closer to the longitudinal end of each cam 10, 10 'which has the contact area C, C' (to the left of the Y, Y 'axes) in the figures) that the longitudinal end of the cam 10, 10 'which has the hook zone D, D' (to the right of the axes Y, Y 'in the figures). Thus, the moment of force is greater for the hook function implemented by the hook zones D, D 'than for the contact function implemented by the contact areas C, C'.

Toutefois, il est aussi possible que l'axe Y, Y' de chaque came 10, 10' soit positionné sensiblement à égale distance des deux extrémités longitudinales de la came 10, 10', ou que l'axe Y, Y' de chaque came 10, 10' soit positionné plus loin de l'extrémité longitudinale de chaque came 10, 10' qui comporte la zone de contact C, C' que de l'extrémité longitudinale de la came 10, 10' qui comporte la zone en crochet D, D'.However, it is also possible that the Y axis, Y 'of each cam 10, 10' is positioned substantially equidistant from the two longitudinal ends of the cam 10, 10 ', or that the Y axis, Y' of each cam 10, 10 'is positioned further from the longitudinal end of each cam 10, 10' which comprises the contact zone C, C ' than the longitudinal end of the cam 10, 10 'which has the hook zone D, D'.

Par ailleurs, la surface de la zone de contact C, C' et la surface de la zone en crochet D, D' de chaque came est arrondie : c'est-à-dire que dans ces zones, il n'y a pas de surface plane qui serait parallèle à l'axe de rotation de la came ; chaque surface de zone est courbe avec au moins un, voir plusieurs, rayon(s) de courbure selon un axe parallèle à l'axe Y ; Y' de rotation des cames.Moreover, the surface of the contact zone C, C 'and the surface of the hook zone D, D' of each cam is rounded: that is to say that in these zones, there is no flat surface that would be parallel to the axis of rotation of the cam; each zone surface is curved with at least one, or more, radius (s) of curvature along an axis parallel to the Y axis; Y 'rotation of the cams.

Comme visible en figure 3, en position porte maintenue ouverte, chaque came 10, 10' s'oppose au rappel par la partie de rappel.As visible in figure 3 in the open-maintained holding position, each cam 10, 10 'opposes the return by the return portion.

Chaque zone s'étend sur une largeur (mesurée parallèlement aux axes Y, Y') comprise par exemple entre 1 et 2 cm. Toutes les zones présentent ici la même largeur et les deux cames présentent ainsi une largeur constante sur toute leur longueur.Each zone extends over a width (measured parallel to the Y, Y 'axes), for example between 1 and 2 cm. All the zones here have the same width and the two cams thus have a constant width over their entire length.

Chaque zone de contact C, C' coopère avec une zone complémentaire qui est situé à l'extrémité du doigt 1 qui est liée mécaniquement au moyen de rappel (ressort de rappel 4). Cette extrémité du doigt 1 présente une largeur (mesurée parallèlement aux axes Y, Y') sensiblement identique à la largeur des cames 10, 10'.Each contact zone C, C 'cooperates with a complementary zone which is located at the end of the finger 1 which is mechanically linked to the return means (return spring 4). This end of the finger 1 has a width (measured parallel to the axes Y, Y ') substantially identical to the width of the cams 10, 10'.

Du fait que le doigt présente une section rectangulaire, les deux zones complémentaires à l'extrémité du doigt 1 sont ici réalisées par deux surfaces qui sont chacune inclinées d'un angle d'environ 45 ° par rapport à l'axe X et orientée en pointe, vers cet axe. Le contact entre les zones de contact C, C' et les zones complémentaires à l'extrémité du doigt 1 est toujours le même : il s'agit d'un contact d'un contact de type « linéique ». Cette coopération est illustrée en détail sur la figure 4.Because the finger has a rectangular section, the two complementary areas at the end of the finger 1 are here made by two surfaces which are each inclined at an angle of about 45 ° with respect to the X axis and oriented in point towards this axis. The contact between the contact areas C, C 'and the complementary zones at the end of the finger 1 is always the same: it is a contact of a "linear" type contact. This cooperation is illustrated in detail on the figure 4 .

On peut voir par ailleurs sur cette figure 4 que la section intérieure du carter intermédiaire 8 est rectangulaire, avec une largeur du rectangle (mesurée parallèlement aux axes Y, Y') juste très légèrement supérieure à la largeur des cames 10, 10'.We can see elsewhere on this figure 4 that the inner section of the intermediate casing 8 is rectangular, with a width of the rectangle (measured parallel to the Y, Y 'axes) just slightly greater than the width of the cams 10, 10'.

Chaque zone en crochet D, D' coopère avec une zone complémentaire qui est liée mécaniquement au moyen de retenue électromagnétique et plus précisément qui est liée à la contre-plaque 14.Each hook zone D, D 'cooperates with a complementary zone which is mechanically connected to the electromagnetic retention means and more precisely which is connected to the counterplate 14.

Ici, les zones en crochet D, D' des deux cames 10, 10' coopèrent chacune avec une tige 11 unique en forme de T dont le tronc est coaxial avec l'axe longitudinal central X. Les deux branches du T sont orientés sensiblement perpendiculairement à l'axe X et présentent chacune une largeur sensiblement identique à la largeur des cames 10, 10'.Here, the hook zones D, D 'of the two cams 10, 10' each cooperate with a single T-shaped rod 11 whose trunk is coaxial with the central longitudinal axis X. The two branches of the T are oriented substantially perpendicularly. at the X axis and each have a width substantially identical to the width of the cams 10, 10 '.

Le contact entre les zones en crochet D, D' et les zones complémentaires des branches du T est toujours le même : il s'agit d'un contact de type « portion de plan ».The contact between the hook zones D, D 'and the complementary zones of the branches of the T is always the same: it is a contact of the "plan portion" type.

Toutefois, pour assurer que les deux segments de droite soient toujours bien parallèles, le tronc de la forme en T est mobile en rotation selon un axe Z qui est perpendiculaire à l'axe X. Pour ce faire, le tronc de la tige 11 présente à son extrémité opposées aux branche un trou débouchant à ses deux extrémité et orienté selon l'axe Z. Un arbre cylindrique 13 est glissé dans ce trou pour permettre au tronc de tourner autour du cylindre. Ce cylindre est lui-même glissé dans un trou orienté selon l'axe Z et ménagé dans la contre-plaque 14. Cet assemblage par ailleurs d'offrir un degré de liberté par rapport à l'axe Z de la contre-plaque 14 par rapport à la face électromagnétique positionnée en vis-à-vis.However, to ensure that the two straight segments are always well parallel, the trunk of the T-shape is rotatable along an axis Z which is perpendicular to the axis X. To do this, the trunk of the rod 11 has at its end opposite the branch a hole opening at both ends and oriented along the axis Z. A cylindrical shaft 13 is slid into this hole to allow the trunk to rotate around the cylinder. This cylinder is itself slid into a hole oriented along the Z axis and arranged in the counter plate 14. This assembly also offers a degree of freedom with respect to the Z axis of the counter plate 14. relative to the electromagnetic face positioned vis-à-vis.

ARMEMENT DU SYSTEME DE RETENUE (passage de la figure 2 à la figure 3) :ARMING THE RETENTION SYSTEM (passage from Figure 2 to Figure 3):

Lors de l'ouverture de la porte, le doigt 1, sous l'effet du ressort de rappel 4 suit le mouvement du piston de la partie de rappel B. Le doigt 1 tend à sortir de l'espace intérieur du carter intermédiaire 8. La contreplaque 14, sous l'effet de quatre ressorts de compression 12 entraine la tige 11, qui, par l'intermédiaire des deux zones en crochet D, D', provoque la rotation des cames 10, 10' respectivement autour des axes Y, Y', qui viennent en position de blocage (figure 3), interdisant le retour de doigt 1, par appui des zones de contact C, C' contre le doigt 1.When the door is opened, the finger 1, under the effect of the return spring 4, follows the movement of the piston of the return portion B. The finger 1 tends to come out of the interior space of the intermediate casing 8. The counterplate 14, under the effect of four compression springs 12 drives the rod 11, which, via the two hook zones D, D ', causes the cams 10, 10' respectively to rotate about the Y axes, Y ', which come to the blocking position ( figure 3 ), prohibiting the return of finger 1, by pressing the contact areas C, C 'against the finger 1.

Ainsi, la contreplaque 14 vient en contact avec la ventouse 16 qui est vissée à son extrémité droite sur le carter mécanique 15, lui-même vissé à son extrémité gauche sur le carter intermédiaire 8. Lorsque de la ventouse 16 est alimentée en courant électrique, elle assure le maintien en position de la contreplaque 14, ce qui a pour effet de maintenir les zones de contact C, C' plaquées contre l'extrémité du doigt 1.Thus, the counterplate 14 comes into contact with the suction cup 16 which is screwed at its right end to the mechanical casing 15, itself screwed at its left end to the intermediate casing 8. When the suction cup 16 is supplied with electric current, it maintains the position of the counterplate 14, which has the effect of keeping the contact areas C, C 'pressed against the end of the finger 1.

Comme visible en figure 3, dans cette position, l'axe de blocage 1 pénètre sur quelques millimètres seulement dans le carter intermédiaire 8.As visible in figure 3 in this position, the locking pin 1 penetrates a few millimeters only in the intermediate casing 8.

DEVERROUILLAGEUNLOCK Par rupture de courantBy power failure

En cas de rupture de courant, la partie de rappel B tend à ramener le doit 1 dans sa position initiale (extrémité du doigt 1 essentiellement dans le carter intermédiaire 8, ce qui a pour effet de ramener la contre plaque 14 en position éloignée de la ventouse 16, la ventouse n'opposant pas d'effort résistant.In the event of a power failure, the return part B tends to return the must 1 to its initial position (end of the finger 1 essentially in the housing intermediate 8, which has the effect of bringing the back plate 14 away from the suction cup 16, the suction cup not opposing any resistant force.

ForcéStrength

En cas de forçage sur la porte, cela entraine un effort qui est transmis au doigt 1 par le piston de la partie de rappel B, qui tend à le ramener dans sa position initiale « porte fermée », telle qu'illustrée en figure 2.In the event of forcing on the door, this causes a force which is transmitted to the finger 1 by the piston of the return portion B, which tends to return it to its initial "closed door" position, as illustrated in FIG. figure 2 .

Cet effort est transmis à la contreplaque 14 via les cames 10 et d'une part les surfaces inclinées du doigt 1 coopérant avec les zones de contact C, C' et d'autre part les surfaces inclinées de la tige 11 coopérant avec les zones en crochet D, D'.This force is transmitted to the counterplate 14 via the cams 10 and on the one hand the inclined surfaces of the finger 1 cooperating with the contact areas C, C 'and on the other hand the inclined surfaces of the rod 11 cooperating with the zones hook D, D '.

L'effort résultant au niveau de la contreplaque 14 s'oppose à celui de la ventouse 16. Lorsque l'effort résultant est supérieur à l'effort de maintien de la ventouse 16, le système se déverrouille (passage de la position de la figure 3 à la position de la figure 2).The resulting force at the level of the counterplate 14 opposes that of the suction cup 16. When the resulting force is greater than the holding force of the suction cup 16, the system unlocks (passage of the position of the figure 3 at the position of the figure 2 ).

Réglage de l'angle de maintien porte ouverteAdjustment of the open door angle

La position du doigt 1 est dépendante de l'angle d'ouverture de la porte, il est donc possible de régler l'angle de verrouillage de la porte en agissant sur la position du carter intermédiaire 8 par rapport au bouchon 5.The position of the finger 1 is dependent on the opening angle of the door, it is therefore possible to adjust the locking angle of the door by acting on the position of the intermediate casing 8 with respect to the cap 5.

La bague de réglage 6 dispose d'un filetage intérieur gauche/droit. Les deux parties de ce filetage sont séparées par un épaulement ; ce filetage permet de régler la position relative axiale du carter intermédiaire 8 par rapport au bouchon 5, en vissant ou dévissant le carter intermédiaire 8 et donc la position relative axiale des axes Y, Y' des cames 10, 10' par rapport au doigt 1.The adjusting ring 6 has a left / right internal thread. The two parts of this thread are separated by a shoulder; this threading makes it possible to adjust the axial relative position of the intermediate casing 8 with respect to the plug 5, by screwing or unscrewing the intermediate casing 8 and thus the axial relative position of the Y, Y 'axes of the cams 10, 10' relative to the finger 1 .

Ecarter le carter intermédiaire 8 du bouchon 5, revient à diminuer l'angle de maintien de la porte. A l'inverse, rapprocher le carter intermédiaire 8 du bouchon 5 revient à augmenter l'angle de maintien de la porte.Spread the intermediate casing 8 of the cap 5, is to reduce the angle of the door. Conversely, bringing the intermediate casing 8 of the cap 5 closer to increasing the holding angle of the door.

L'angle minimum d'accrochage est obtenu en bridant le déplacement relatif entre la bague de réglage 6 et le carter intermédiaire 8 : une butée (non illustrée) est en liaison complète avec le carter intermédiaire 8 : elle dispose d'une tête passant de l'autre côté distant de la bague de réglage 6. L'angle minimum est atteint lorsque la tête de la butée vient en appui sur la bague 6.The minimum angle of attachment is obtained by clamping the relative displacement between the adjusting ring 6 and the intermediate casing 8: a stop (not shown) is in complete connection with the intermediate casing 8: it has a head passing from the other remote side of the adjusting ring 6. The minimum angle is reached when the head of the stop abuts on the ring 6.

Le blocage du réglage de l'angle est obtenu via des vis en prise dans le carter intermédiaire 8. Pour bloquer le réglage, les vis sont serrées sur la partie de rappel B ce qui permet de bloquer la partie à retenue électromagnétique A.The locking of the angle adjustment is obtained via screws engaged in the intermediate casing 8. To lock the adjustment, the screws are tightened on the return portion B which blocks the electromagnetic retention portion A.

Réglage de l'effort de maintien porte ouverteAdjustment of the open door holding force

Par ailleurs, il est possible de régler l'effort de maintien en agissant sur la position de la ventouse 16 par rapport au carter intermédiaire 8 via le carter mécanique 15 les reliant. Reculer la ventouse 16 par rapport à la contre-plaque adjacente montée dans le carter mécanique 15 engendre entraine une diminution l'intensité de l'effort de retenue.Furthermore, it is possible to adjust the holding force by acting on the position of the suction cup 16 relative to the intermediate casing 8 via the mechanical housing 15 connecting them. Returning the suction cup 16 relative to the adjacent counter plate mounted in the mechanical housing 15 causes a decrease in the intensity of the retaining force.

Les cames 10 agissent comme un démultiplicateur de l'effort de la ventouse 16.The cams 10 act as a multiplier of the force of the suction cup 16.

Le nombre très réduit de pièces en mouvement les unes par rapport aux autres dans le ferme-porte selon l'invention ainsi que l'utilisation de came(s) à zones de contact et en crochet qui diminuent les pressions de contact (par rapport à des appuis ponctuels) permet de réaliser un ferme-porte très fiable, qui passe les tests de fiabilité mentionnés ci-avant.The very small number of moving parts relative to each other in the door closer according to the invention as well as the use of cam (s) with contact and hook zones which reduce the contact pressures (with respect to punctual support) allows for a very reliable door closer, which passes the reliability tests mentioned above.
