Description

La présente invention a pour objet une porte, notamment une porte coupe-feu montée dans un local public tel qu'un hôpital ou une école et comprenant un châssis dormant muni d'une traverse supérieure essentiellement horizontale ainsi que de deux vantaux, à savoir un vantail de service, en règle générale équipé d'une poignée et un vantail semi-fixe lui-même non équipé d'une poignée.The present invention relates to a door, in particular a fire door mounted in a public place such as a hospital or a school and comprising a sleeping frame provided with a substantially horizontal upper cross member and two leaves, namely a service leaf, usually equipped with a handle and a semi-fixed leaf itself not equipped with a handle.

Ces vantaux sont mobiles entre une position ouverte et une position fermée et sont respectivement rappelés mécaniquement vers la position fermée par un ferme-porte connu en lui-même équipé d'un bras d'actionnement soumis à l'action de ressorts de rappel.These leaves are movable between an open position and a closed position and are respectively mechanically biased to the closed position by a door closer known in itself equipped with an actuating arm subjected to the action of return springs.

La porte coupe-feu conforme à l'invention est en outre équipée d'un dispositif de sécurité ayant principalement une triple fonction consistant à :

  • permettre une fermeture mécanique des vantaux grâce au ferme-porte,
  • permettre de maintenir les vantaux en position ouverte en fonctionnement normal et de commander automatiquement leur fermeture mécanique par les ferme-portes, notamment en cas de détection d'un incendie sous l'action d'un signal transmis par une centrale incendie indépendante ou tout autre système, et également
  • assurer une fonction de sélection de nature à garantir que lors de la fermeture automatique, notamment en cas de détection d'un incendie, le vantail semi-fixe se ferme en premier, avant le vantail de service pour éviter un mauvais recouvrement, en particulier de nature à laisser passer le feu.
The fire door according to the invention is furthermore equipped with a safety device having mainly a triple function consisting of:
  • allow a mechanical closing of the leaves thanks to the door closer,
  • allow the leaves to be kept in the open position during normal operation and to automatically control their mechanical closing by the door closers, particularly in the event of detection of a fire under the action of a signal transmitted by an independent fire station or any other system, and also
  • ensure a selection function to ensure that during the automatic closing, especially in the event of fire detection, the semi-fixed leaf closes first, before the operating leaf to avoid a bad recovery, in particular nature to let fire.

Cette porte peut en outre avantageusement avoir une quatrième fonction consistant à transmettre des informations concernant la position des vantaux à la centrale incendie ou à tout autre système.This door can also advantageously have a fourth function of transmitting information concerning the position of the leaves to the fire station or any other system.

Il est indispensable que le dispositif de sécurité puisse remplir ces fonctions de manière satisfaisante pour garantir la sécurité des personnes se trouvant dans le local dans lequel est montée la porte, en particulier en cas d'incendie.It is essential that the safety device can perform these functions satisfactorily to ensure the safety of the persons in the room in which the door is mounted, particularly in case of fire.

On a déjà proposé un dispositif de sécurité susceptible de remplir ces fonctions qui est intégré à un profilé formant bandeau ayant en général une section carrée ou rectangulaire monté sur la traverse supérieure du châssis dormant de la porte.It has already been proposed a safety device capable of performing these functions which is integrated with a strip profile having generally a square or rectangular section mounted on the upper cross member of the door frame.

Un tel dispositif de sécurité qui s'est avéré globalement satisfaisant à l'usage du point de vue de la sécurité des personnes comporte, pour chacun des deux vantaux, d'une part un support fixe, portant un électroaimant alimenté en tension, monté à la partie interne du bandeau, et d'autre part, un patin coulissant mobile en translation horizontale, lui aussi à la partie interne du bandeau et équipé d'un axe faisant saillie à la partie externe de celui-ci qui est relié au bras du ferme-porte.Such a safety device, which has proven to be generally satisfactory for the use from the point of view of human security, comprises, for each of the two leaves, on the one hand a fixed support carrying an electromagnet supplied with tension, mounted on the inner part of the strip, and secondly, a sliding shoe movable in horizontal translation, also to the inner part of the strip and equipped with an axis projecting from the external part thereof which is connected to the arm of the close door.

Le support fixe portant l'électroaimant est également muni d'une contreplaque mobile en translation horizontale le long de celui-ci, sur laquelle est articulé un premier crochet monté libre en rotation ; cette contreplaque est maintenue contre l'électroaimant lorsque celui-ci est alimenté en tension.The fixed support carrying the electromagnet is also provided with a movable counterplate in horizontal translation along the latter, on which is articulated a first hook mounted freely in rotation; this counterplate is held against the electromagnet when the latter is supplied with voltage.

Le patin coulissant est quant à lui équipé d'un second crochet situé en regard du premier crochet et s'emboîtant dans celui-ci lors de l'ouverture manuelle de la porte, ainsi que d'une plaquette montée à sa partie arrière à l'opposé du second crochet.The sliding shoe is in turn equipped with a second hook located opposite the first hook and fitting into it when manually opening the door, and a plate mounted at its rear part to the door. opposite of the second hook.

L'électroaimant et la contreplaque maintiennent le premier crochet et le second crochet emboîtés l'un dans l'autre et donc le vantail en position ouverte lorsque l'électroaimant est alimenté en tension.The electromagnet and the counterplate keep the first hook and the second hook nested one inside the other and thus the leaf in the open position when the electromagnet is supplied with voltage.

En cas de coupure du courant, le premier crochet bascule vers le bas de façon à libérer le second crochet et le patin qui coulisse vers l'extérieur en s'éloignant du support fixe portant l'électroaimant pour commander la fermeture du vantail sous l'action du ferme-porte.In the event of a power cut, the first hook swings downwardly so as to release the second hook and the pad that slides outwards away from the fixed support carrying the electromagnet to control the closing of the leaf under the action of the door closers.

Simultanément, un ressort permet d'appliquer à nouveau la contreplaque contre l'électroaimant de façon à réenclencher le dispositif.Simultaneously, a spring makes it possible to reapply the counterplate against the electromagnet so as to reset the device.

Lors de l'ouverture manuelle suivante du vantail, les deux crochets peuvent à nouveau s'emboîter l'un dans l'autre.At the next manual opening of the leaf, the two hooks can again fit into one another.

Ce dispositif de sécurité connu comporte également un sélecteur constitué par une tige de sélecteur montée à la partie interne du bandeau et munie à ses extrémités respectives de roulettes coopérant respectivement avec les plaquettes montées à la partie arrière du patin coulissant associé au vantail de service et du patin coulissant associé au vantail semi-fixe de façon à assurer la fonction de sélection, c'est-à-dire à garantir que, lors de la fermeture automatique, notamment en cas de détection d'un incendie, le vantail semi-fixe se ferme en premier avant le vantail de service pour éviter un mauvais recouvrement, en particulier de nature à laisser passer le feu.This known safety device also comprises a selector consisting of a selector rod mounted to the inner part of the strip and provided at its respective ends with wheels cooperating respectively with the plates mounted at the rear part of the sliding shoe associated with the service leaf and the sliding shoe associated with the semi-fixed leaf so as to ensure the selection function, that is to say to ensure that during the automatic closing, especially in case of detection of a fire, the semi-fixed leaf is closes first before the service leaf to avoid a bad recovery, especially of a nature to let fire.

Malgré son caractère globalement satisfaisant du point de vue de la sécurité des personnes, un tel dispositif de sécurité présente un certain nombre d'inconvénients, en particulier liés au fait qu'il ne peut pas être vendu au détail en quincaillerie mais doit obligatoirement être fabriqué sur mesure du fait du nombre important d'options ce qui augmente son coût dans une large mesure et constitue un obstacle à sa distribution dans de nombreux pays, en particulier de nombreux pays européens.Despite its generally satisfactory character from the point of view of the safety of persons, such a safety device has a certain number of drawbacks, in particular related to the fact that it can not be sold retail hardware but must necessarily be manufactured tailor-made because of the large number of options, which increases its cost to a large extent and is an obstacle to its distribution in many countries, in particular many European countries.

Ces différentes options sont notamment liées à la nécessité de régler en usine de nombreux paramètres tels qu'à titre d'exemple la longueur de la tige de sélecteur en fonction de la largeur des vantaux, le sens de l'arrivée électrique qui est située à l'une des extrémités du bandeau ou encore la tension d'alimentation (24 ou 48 volts).These various options are particularly related to the need to adjust in the factory many parameters such as for example the length of the selector rod depending on the width of the leaves, the direction of the electrical inlet which is located at one end of the strip or the supply voltage (24 or 48 volts).

La présente invention a pour objet de remédier à ces inconvénients en proposant une porte, notamment une porte coupe-feu équipée d'un dispositif de sécurité du type susmentionné intégré à un bandeau monté sur la traverse supérieure du châssis dormant de cette porte présentant un caractère modulable permettant sa distribution au détail en quincaillerie et son montage ultérieur par l'utilisateur.The object of the present invention is to remedy these drawbacks by proposing a door, in particular a fire door equipped with a security device of the above-mentioned type integrated into a strip mounted on the upper cross member of the fixed frame of this door having a character. modular allowing its retail distribution in hardware and its subsequent installation by the user.

Bien entendu, un tel dispositif de sécurité peut également toujours être à la demande, fabriqué sur mesure.Of course, such a safety device can also always be on demand, made to measure.

Selon l'invention, le bandeau universel intégrant le dispositif de sécurité est ainsi constitué à chacune de ses extrémités de segments latéraux standards correspondant respectivement au vantail de service et au vantail semi-fixe et d'un segment médian pouvant être coupé par l'utilisateur à la longueur souhaitée.According to the invention, the universal strip incorporating the safety device is thus constituted at each of its ends of standard side segments respectively corresponding to the leaf semi-fixed leaf and a median segment that can be cut by the user to the desired length.

La porte conforme à l'invention est plus précisément caractérisée en ce qu'elle est munie d'un bandeau universel comprenant d'une part une partie médiane recoupable et d'autre part deux segments de bandeau latéraux standards correspondant respectivement au vantail de service et au vantail semi-fixe et renfermant un support fixe portant un électroaimant ainsi qu'un patin coulissant associé à ce vantail.The door according to the invention is more specifically characterized in that it is provided with a universal strip comprising on the one hand a median cut-off portion and on the other hand two standard side strip segments respectively corresponding to the service leaf and with semi-fixed leaf and containing a fixed support carrying an electromagnet as well as a sliding shoe associated with this leaf.

Selon l'invention, chacun des segments latéraux standards renferme également un embout enfichable fixé à celui-ci à sa partie médiane et équipé à son extrémité interne d'une roulette coopérant avec la plaquette montée à la partie arrière du patin coulissant.According to the invention, each of the standard lateral segments also encloses a plug-in endpiece fixed thereto at its median part and equipped at its inner end with a wheel co-operating with the plate mounted at the rear part of the sliding shoe.

Ces embouts enfichables standards constituent ainsi les parties d'extrémité d'une tige de sélecteur.These standard plug-in tips thus constitute the end portions of a selector rod.

Le segments médian recoupable comporte quant à lui un tube, de préférence un tube carré en aluminium de 10 mm constituant la partie centrale de la tige de sélecteur et destiné à être enfiché à ses extrémités respectives sur les embouts enfichables standards portant les roulettes fixés à la partie interne des segments de bandeau latéraux standards respectivement associés au vantail de service et au vantail semi-fixe.The median cut-off segment comprises meanwhile a tube, preferably a 10 mm square aluminum tube constituting the central part of the selector rod and intended to be plugged at its respective ends onto the standard plug-in sleeves carrying the rollers fixed to the internal part of the standard lateral strip segments respectively associated with the service leaf and the semi-fixed leaf.

Pour permettre cet enfichage, l'extrémité externe des embouts enfichables comporte une fiche faisant saillie à la partie externe des segments de bandeau latéraux standards.To enable this plugging, the outer end of the plug-in tips has a plug protruding from the outer portion of the standard sideband segments.

Selon l'invention, le segment médian recoupable du bandeau universel comprend un profilé, de préférence un profilé en U enclipsable, de préférence en aluminium, permettant le recouvrement du tube constituant la partie centrale de la tige de sélecteur, ainsi que deux caches en matière plastique, respectivement destinés à être enclipsés aux extrémités de ce profilé, à ses deux extrémités.According to the invention, the median cut-off segment of the universal strip comprises a profile, preferably an interlocking U-profile, preferably made of aluminum, for covering the tube constituting the central part of the selector rod, as well as two covers made of material plastic, respectively intended to be clipped to the ends of this section, at both ends.

Il est à noter que lors de la pose, le tube constituant la partie centrale de la tige de sélecteur et le profilé de recouvrement sont de préférence coupés à la même longueur pour simplifier cette pose.It should be noted that during installation, the tube constituting the central portion of the selector rod and the covering profile are preferably cut to the same length to simplify this installation.

Le profilé de recouvrement et les deux caches ont une fonction exclusivement d'ordre esthétique et permettent de conférer au bandeau modulaire universel conforme à l'invention, une fois monté, un aspect similaire à celui d'un bandeau en une seule pièce fabriqué sur mesure.The cover profile and the two covers have an exclusively aesthetic function and make it possible to give the universal modular strip according to the invention, once mounted, an appearance similar to that of a one-piece strip made to measure .

Selon une caractéristique préférentielle de l'invention, le segment médian recoupable du bandeau modulaire est équipé d'une nappe informatique, en particulier d'une nappe informatique 14 fils munie de connecteurs rapides enclipsables, fixée sur le tube constituant la partie centrale de la tige de sélecteur et permettant la liaison des deux segments de bandeau latéraux standards entre eux et avec les organes de commande de la porte pour permettre le fonctionnement correct de cette porte.According to a preferred feature of the invention, the exchangeable middle segment of the modular strip is equipped with a computer web, in particular a 14-wire computer web provided with snap-fit quick connectors, fixed on the tube constituting the central part of the rod. selector and allowing the connection of the two standard lateral strip segments between them and with the control members of the door to allow the correct operation of this door.

Selon une autre caractéristique de l'invention, les embouts portant les roulettes enfichés dans le tube recoupable constituant la partie centrale de la tige de sélecteur sont respectivement équipés de paliers conçus pour permettre la rotation de cette tige sur environ au maximum un quart de tour et son rappel automatique.According to another characteristic of the invention, the end pieces carrying the rollers inserted into the cut-out tube constituting the central part of the selector rod are respectively equipped with bearings designed to allow the rotation of this rod for a maximum of at least a quarter of a turn and its automatic recall.

La plaquette du patin coulissant de l'embout du segment de bandeau latéral associé au vantail semi-fixe a quant à elle une forme en biseau à son extrémité tandis que la plaquette du patin coulissant de l'embout du segment de bandeau latéral associé au vantail de service a une extrémité en équerre.The slider pad of the end of the lateral strip segment associated with the semi-fixed leaf has a bevel shape at its end while the slider pad of the end of the side strip segment associated with the leaf service at one end at right angle.

Compte tenu de cette configuration, lors de la fermeture automatique de la porte sous l'action du ferme-porte, la roulette de l'embout du segment de bandeau latéral associé au vantail semi-fixe roule sur l'extrémité en biseau de la plaquette du patin coulissant de ce segment de bandeau latéral, alors que la roulette de l'embout du segment de bandeau latéral associé au vantail de service bute contre l'extrémité en équerre de la plaquette du patin coulissant de ce segment de bandeau de façon à garantir que le vantail semi-fixe se ferme en premier.Given this configuration, when the door closes automatically under the action of the door closer, the caster wheel of the end of the lateral strip segment associated with the semi-fixed leaf rolls on the beveled end of the plate sliding shoe of this segment of lateral strip, while the roulette of the tip of the segment of side strip associated with the service leaf abuts against the angled end of the plate of the sliding pad of this segment of strip so as to guarantee the semi-fixed leaf closes first.

Simultanément, en roulant sur l'extrémité en biseau de la plaquette du patin coulissant du segment de bandeau latéral associé au vantail semi-fixe, la roulette de l'embout de ce segment de bandeau fait tourner la tige de sélecteur d'environ un quart de tour de façon à permettre à la plaquette du patin coulissant du segment de bandeau latéral associé au vantail de service de passer sous la roulette de l'embout de ce segment de bandeau et par suite permettre la fermeture décalée de ce vantail.Simultaneously, by rolling on the beveled end of the slider pad slider of the side strip segment associated with the semi-fixed leaf, the wheel of the tip of this segment of the strip makes turn the selector rod about a quarter of a turn so as to allow the slider pad slider of the side strip segment associated with the service leaf to pass under the wheel of the tip of this segment of strip and consequently allow the offset closure of this leaf.

Selon une autre caractéristique de l'invention, le bandeau universel est associé à une carte électronique permettant d'alimenter les électroaimants en fonctionnement normal, la porte étant ouverte et de détecter la tension d'alimentation, en particulier de déterminer si cette tension est égale à 24 volts ou à 48 volts.According to another characteristic of the invention, the universal strip is associated with an electronic card making it possible to supply the electromagnets during normal operation, the door being open and to detect the supply voltage, in particular to determine whether this voltage is equal. at 24 volts or 48 volts.

A cet effet, les électroaimants des supports fixes équipant les segments de bandeau latéraux sont avantageusement équipés d'au moins deux bobines dont la carte électronique commande le branchement en série ou en parallèle selon que la tension d'entrée détectée est de 24 volts ou de 48 volts.For this purpose, the electromagnets of the fixed supports equipping the lateral strip segments are advantageously equipped with at least two coils whose electronic card controls the connection in series or in parallel depending on whether the input voltage detected is 24 volts or less. 48 volts.

Selon une caractéristique préférentielle de l'invention, le bandeau universel est symétrique et réversible et est équipé d'un dispositif d'alimentation en tension à chacune de ses extrémités.According to a preferred feature of the invention, the universal strip is symmetrical and reversible and is equipped with a voltage supply device at each of its ends.

Il est à noter que ce caractère symétrique et réversible peut également s'adapter au bandeau d'un dispositif de sécurité fabriqué sur mesure à la demande.It should be noted that this symmetrical and reversible character can also adapt to the headband of a security device made to measure on demand.

Il est également à noter que le bandeau modulaire du dispositif de sécurité équipant la porte conforme à l'invention a un caractère très largement universel dans la mesure où il peut également s'adapter à une porte exempte de sélecteur si le segment médian recoupable n'est pas équipé d'un tube central mais uniquement d'un profilé de recouvrement et de deux caches, voire à une porte ne comportant qu'un seul vantail s'il n'est équipé que d'un seul segment de bandeau latéral.It should also be noted that the modular headband of the safety device fitted to the door according to the invention has a very largely universal character insofar as it can also be adapted to a selector-free door if the median cross-cut segment is not equipped with a central tube but only with a cover profile and two covers, or with a door with only one leaf if it is equipped with only one segment of lateral strip.

Selon une autre caractéristique de l'invention, le bandeau est équipé de capteurs susceptibles de transmettre des informations concernant la position des vantaux, c'est-à-dire leur position ouverte ou fermée à la centrale incendie ou à tout autre système.According to another characteristic of the invention, the strip is equipped with sensors capable of transmitting information concerning the position of the leaves, that is to say their open or closed position to the fire station or any other system.

Selon une autre caractéristique de l'invention, le bandeau est équipé d'organes de temporisation permettant de maintenir les bandeaux en position ouverte pendant une durée prédéfinie réglable après ouverture manuelle.According to another characteristic of the invention, the strip is equipped with timing devices making it possible to maintain the strips in open position for a preset time adjustable after manual opening.

Ces organes de temporisation permettent en particulier à un utilisateur ayant ouvert les vantaux de les bloquer en position ouverte pendant une durée programmée afin de lui permettre de faire passer des objets encombrants ou pour des raisons autres.In particular, these delaying members allow a user who has opened the leaves to lock them in the open position for a programmed duration in order to allow him to pass bulky objects or for other reasons.

Les vantaux se referment automatiquement lorsque cette durée programmée est écoulée.The leaves close automatically when this programmed time has elapsed.

Selon une autre caractéristique de l'invention, le bandeau est équipé d'organes antiréarmement désactivables devant être actionnés manuellement par un utilisateur après fermeture automatique des vantaux, notamment en cas de détection d'un incendie pour permettre le fonctionnement ultérieur du dispositif de sécurité.According to another characteristic of the invention, the strip is equipped with deactivatable anti-armament devices to be manually actuated by a user after automatic closing of the leaves, in particular in the event of detection of a fire to allow the subsequent operation of the safety device.

Un tel actionnement manuel peut notamment correspondre à un appui par l'utilisateur sur un bouton-poussoir monté à cet effet sur le bandeau.Such manual actuation can in particular correspond to a support by the user on a push-button mounted for this purpose on the headband.

Selon une autre caractéristique de l'invention, le bandeau est équipé d'organes de décondamnation à commande électrique dont l'actionnement manuel par un utilisateur permet de débloquer les vantaux et donc de les fermer lorsqu'ils sont en position ouverte.According to another characteristic of the invention, the strip is equipped with electrically controlled unlocking members whose manual actuation by a user makes it possible to unlock the leaves and thus to close them when they are in the open position.

Cet actionnement manuel peut là encore correspondre à l'appui sur un bouton-poussoir monté sur le bandeau.This manual actuation can again correspond to pressing a push button mounted on the headband.

Selon une autre caractéristique de l'invention, le dispositif de sécurité est équipé d'une électronique intelligente lui permettant de communiquer avec un utilisateur, notamment pour lui signaler des défauts de fonctionnement, d'installation, ou de configuration.According to another characteristic of the invention, the security device is equipped with intelligent electronics enabling it to communicate with a user, in particular to point out malfunctions, installation, or configuration.

Cette communication peut, à titre d'exemple, être établie au moyen d'une diode clignotant à des fréquences différentes en fonction des cas.This communication can, for example, be established by means of a flashing diode at different frequencies depending on the case.

L'invention se rapporte également à un dispositif de sécurité intégré à un profilé formant bandeau équipant une porte, notamment une porte coupe-feu du type susmentionné.The invention also relates to a safety device integrated into a strip forming section equipping a door, including a fire door of the aforementioned type.

Selon la figure 41 , lorsque l'électroaimant 9 du support fixe 7 est alimenté en tension, la contreplaque 10 est maintenue contre celui-ci et le premier crochet et le second crochet 13 sont emboîtés l'un dans l'autre ; le vantail 21, 22 est ainsi maintenu en position ouverte.According to figure 4 1 when the electromagnet 9 of the fixed support 7 is supplied with voltage, the counterplate 10 is held against it and the first hook and the second hook 13 are nested one inside the other; leaf 2 1 , 2 2 is thus kept in the open position.

Selon les figures 42 et 43 , en cas de coupure du courant, la contreplaque 10 se désolidarise de l'électroaimant 9 et n'est plus maintenue par celui-ci comme schématisé par la flèche (a) ; le premier crochet bascule alors vers le bas comme schématisé par la flèche (b) de façon à libérer le second crochet 13 et le patin coulissant 8 qui se déplace vers l'extérieur en s'éloignant du support fixe 7 comme représenté par la flèche (c) sous l'action du ferme-porte 3 pour commander la fermeture du vantail 21, 22.According to Figures 4 2 and 4 3 , in case of power failure, the counterplate 10 disengages from the electromagnet 9 and is no longer maintained by it as shown schematically by the arrow (a); the first hook then flips downwards as shown by the arrow (b) of in order to release the second hook 13 and the sliding shoe 8 which moves outwards away from the fixed support 7 as represented by the arrow (c) under the action of the door closer 3 to control the closing of the leaf 2 1 , 2 2 .

A partir de la position finale représentée sur la figure 43 , en cas de remise sous tension de l'électroaimant 9, la contreplaque 10 s'applique à nouveau contre celui-ci et le premier crochet 11 bascule à nouveau vers le haut dans la position représentée sur la figure 41 ; l'ouverture manuelle du vantail 21, 22 entraîne alors le déplacement du patin coulissant 8 vers le support fixe 7 selon la flèche (d) et le réenclenchement du dispositif suite à l'emboîtement du premier crochet 11 et du second crochet 13 comme représenté sur la figure 41 .From the final position shown on the figure 4 3 when the electromagnet 9 is turned back on, the counterplate 10 is again applied against it and the first hook 11 again swings upwards in the position shown in FIG. Figure 4 1 ; the manual opening of the leaf 2 1 , 2 2 then causes the sliding shoe 8 to move towards the fixed support 7 according to the arrow (d) and the reclosing of the device following the interlocking of the first hook 11 and the second hook 13 as represented on the figure 4 1 .

Selon la figure 5, le bandeau 5 est également muni à sa partie interne d'une tige de sélecteur centrale 16 fixée entre les patins coulissants 8 respectivement associés au vantail semi-fixe 21 et au vantail de service 22 et montée sur des paliers 20 réalisés pour permettre sa rotation sur elle-même sur un quart de tour et son rappel.According to figure 5 , the strip 5 is also provided at its inner part with a central selector rod 16 fixed between the sliding shoes 8 respectively associated with the semi-fixed leaf 2 1 and the service leaf 2 2 and mounted on bearings 20 made to allow its rotation on itself on a quarter turn and its recall.

La tige de sélecteur 16 est équipée à ses extrémités de roulettes 17 coopérant respectivement avec les plaquettes 15 montées à la partie arrière des patins coulissants 8 respectivement associés au vantail semi-fixe 21 et au vantail de service 22.The selector rod 16 is equipped at its ends with rollers 17 cooperating respectively with the plates 15 mounted at the rear part of the sliding shoes 8 respectively associated with the semi-fixed leaf 2 1 and the service leaf 2 2 .

Comme il sera décrit plus en détails dans la suite de cet exposé, la fonction de cette tige de sélecteur 16 consiste à garantir qu'en cas de fermeture automatique de la porte, le vantail semi-fixe 21 se ferme en premier avant le vantail de service 22.As will be described in more detail later in this presentation, the function of this selector rod 16 is to ensure that in case of automatic closing of the door, the semi-fixed leaf 2 1 closes first before the leaf service 2 2 .

Comme il résulte des figures 61 et 62 , les plaquettes 15 du patin coulissant 8 associé au vantail semi-fixe 21 et du patin coulissant 8 associé au vantail de service 22 ont une configuration quelque peu différente.As results from Figures 6 1 and 6 2 , the pads 15 of the sliding shoe 8 associated with the semi-fixed leaf 2 1 and sliding shoe 8 associated with the service leaf 2 2 have a somewhat different configuration.

Selon la figure 61 , la plaquette 152 du patin coulissant 8 associé au vantail de service 22 a une extrémité en équerre 18.According to figure 6 1 the plate 2 of the sliding shoe 8 associated with the operating leaf 2 2 has an angled end 18.

Selon la figure 62 , la plaquette 151 du patin coulissant 8 associé au vantail semi-fixe 21 a quant à elle une extrémité 19 en forme de biseau.According to the f igure 6 2 the plate 15 1 of the sliding shoe 8 associated with the semi-fixed leaf 2 1 has its end 19 in the form of a bevel.

Selon la figure 71 , lors de la fermeture automatique de la porte, les ferme-portes 3 rappellent automatiquement les patins coulissants 8 associés au vantail semi-fixe 21 et au vantail de service 22 vers les roulettes 17 équipant la tige de sélecteur 16.According to figure 7 1 when the door is closed automatically, the door closers 3 automatically return the sliding runners 8 associated with the semi-fixed leaf 2 1 and the operating leaf 2 2 to the rollers 17 fitted to the selector rod 16.

Au cours de ce déplacement, l'extrémité en biseau 19 de la plaquette 151 du patin coulissant 8 associé au vantail semi-fixe 21 peut passer au-dessous de la roulette 17 de la tige de sélecteur 16 située en regard de celle-ci de sorte que cette roulette 17 puisse rouler sur cette extrémité en biseau puis sur la partie de la plaquette 151 contigüe à celle-ci.During this movement, the beveled end 19 of the wafer 15 1 of the sliding shoe 8 associated with the semi-fixed leaf 2 1 can pass below the wheel 17 of the selector rod 16 located opposite the ci so that this wheel 17 can roll on this beveled end and then on the portion of the wafer 1 adjacent to it.

En revanche, l'extrémité en équerre 18 de la plaquette 152 du patin coulissant 8 associé au vantail de service 22 vient buter contre la roulette 17 de la tige de sélecteur 16 située en regard de celle-ci de façon à garantir que le vantail semi-fixe 21 se ferme avant le vantail de service 22.On the other hand, the angled end 18 of the wafer 15 2 of the sliding shoe 8 associated with the operating leaf 2 2 abuts against the roller 17 of the selector rod 16 situated opposite it so as to guarantee that the semi-fixed leaf 2 1 closes before the leaf 2 2 .

Toutefois, et selon la figure 72 , le roulement de la roulette 17 de la tige de sélecteur 16 sur l'extrémité en biseau 19 de la plaquette 151 du patin coulissant 8 associé au vantail semi-fixe 21 lors du déplacement de ce patin coulissant selon la flèche (e), entraîne la rotation de la tige de sélecteur 16 d'un quart de tour comme représenté par la flèche (f).However, and according to the figure 7 2 the rolling of the roller 17 of the selector rod 16 on the beveled end 19 of the plate 15 1 of the sliding shoe 8 associated with the semi-fixed leaf 2 1 during the displacement of this sliding shoe according to the arrow (e) , causes the rotation of the selector rod 16 by a quarter of a turn as represented by the arrow (f).

L'extrémité en équerre 18 de la plaquette 152 du patin coulissant 8 associé au vantail de service 22 n'est alors plus bloquée par la roulette 17 de la tige de sélecteur 16 située en regard de celle-ci.The angled end 18 of the plate 15 2 of the sliding shoe 8 associated with the operating leaf 2 2 is then no longer blocked by the roller 17 of the selector rod 16 located opposite it.

Selon la figure 73 , le patin coulissant 8 associé au vantail de service 22 peut alors se déplacer en passant sous cette roulette 17 comme schématisé par la flèche (g) pour permettre la fermeture du vantail de service 22.According to figure 7 3 , the sliding shoe 8 associated with the service leaf 2 2 can then move under this wheel 17 as shown schematically by the arrow (g) to allow the closing of the service leaf 2 2 .

Selon la figure 8, le bandeau universel 5 conforme à l'invention n'est pas monobloc mais comprend un segment médian recoupable 21 ainsi que deux segments latéraux standards 221, 222 qui correspondent respectivement au vantail semi-fixe 21 et au vantail de service 22 et sont respectivement équipés d'une arrivée électrique 23 à leur extrémité.According to figure 8 , the universal strip 5 according to the invention is not monobloc but comprises a median cross-cut segment 21 and two standard lateral segments 22 1 , 22 2 which correspond respectively to the semi-fixed leaf 2 1 and the service leaf 2 2 and are respectively equipped with an electric inlet 23 at their end.

De façon non représentée sur les figures, les segments latéraux standards 221, 222 renferment chacun à leur partie interne un support fixe 7 portant un électroaimant 9 ainsi qu'un patin coulissant 8 identiques à ceux représentés sur les figures 2, 3, 41, 42, 43, 61 et 62 .In a manner not shown in the figures, the standard lateral segments 22 1 , 22 2 each enclose at their inner part a fixed support 7 carrying an electromagnet 9 and a sliding shoe 8 identical to those shown in FIGS. Figures 2, 3, 4 1 , 4 2 , 4 3 , 6 1 and 6 2 .

Selon la figure 10, la tige de sélecteur 16 du bandeau universel conforme à l'invention est en revanche constituée par un tube carré recoupable 24 constituant la partie centrale de cette tige 16 ainsi que par deux embouts enfichables 25 constituant les parties d'extrémité de celle-ci.According to figure 10 , the selector rod 16 of the universal strip according to the invention is instead constituted by a square cut tube 24 constituting the central portion of the rod 16 and by two plug-in connectors 25 constituting the end portions thereof.

Le tube médian 24 est fixé à la partie interne du segment médian recoupable 21 du bandeau universel 5 et est coupé à la même longueur tandis que les embouts enfichables 25 sont respectivement fixés à la partie interne des segments de bandeau latéraux standards 221, 222.The median tube 24 is fixed to the inner part of the center cut-out segment 21 of the universal strip 5 and is cut to the same length while the plug-in tips 25 are respectively fixed to the inner part of the standard side strip segments 22 1 , 22 2 .

Les embouts enfichables 25 sont plus précisément montés sur des paliers 26 permettant la rotation de l'ensemble de la tige de sélecteur 16 sur un quant de tour.The plug-in tips 25 are more precisely mounted on bearings 26 allowing rotation of the entire selector rod 16 over a period of revolution.

Selon les figures 10 et 11, les embouts enfichables 25 constituant les parties d'extrémité de la tige de sélecteur 16 sont équipés à leur extrémité interne de roulettes 17 coopérant respectivement avec les plaquettes 151, 152 des patins coulissants 8 associés au vantail semi-fixe 21 et au vantail de service 22 et à leur extrémité externe opposée aux roulettes 17 d'une fiche 27 faisant saillie à l'extérieur des segments latéraux standards 221, 222 comme représenté sur la figure 11.According to Figures 10 and 11 the plug ends 25 constituting the end portions of the selector rod 16 are equipped at their inner end with rollers 17 cooperating respectively with the plates 15 1 , 15 2 of the sliding shoes 8 associated with the semi-fixed leaf 2 1 and with the operating leaf 2 2 and at their external end opposite the wheels 17 of a plug 27 projecting outside the standard side segments 22 1 , 22 2 as shown in FIG. figure 11 .

Ces fiches 27 permettent l'enfichage des embouts 25 constituant les parties d'extrémité de la tige de sélecteur 16 dans le tube carré 24 constituant la partie centrale de cette tige 16 de façon à conférer à celle-ci un caractère monobloc.These plugs 27 allow the plugs 25 constituting the end portions of the selector rod 16 to be inserted into the square tube 24 constituting the central part of this rod 16 so as to give the latter a one-piece character.

Selon les figures 8, 9A et 9B, le tube 24 constituant la partie centrale de la tige de sélecteur 16 est recouvert par un profilé en U enclipsable 28 recoupable à la même longueur que ce tube 24.According to Figures 8, 9A and 9B , the tube 24 constituting the central part of the selector rod 16 is covered by an interlocking U-shaped section 28 cut to the same length as this tube 24.

Le segment médian recoupable 21 du bandeau universel 5 conforme à l'invention est ainsi constitué par le tube carré central 24 et par le profilé en U enclipsable de recouvrement 28.The median cross-cut segment 21 of the universal strip 5 according to the invention thus consists of the central square tube 24 and the overlapping U-shaped cover section 28.

Des caches 29 sont respectivement enclipsés autour de la tige de sélecteur 16 entre les segments latéraux 221, 222 et le profilé de recouvrement 28 de sorte que le bandeau universel 5 conforme à l'invention ait un aspect similaire à celui d'un bandeau monobloc non recoupable.Covers 29 are respectively snapped around the selector rod 16 between the lateral segments 22 1 , 22 2 and the covering profile 28 so that the universal strip 5 according to the invention has a similar appearance to that of a strip unbreakable monobloc.
