Abstract

A pinion 9 attached to a door meshes with two parallel racks 10, 11 which face each other. A piston 14, connected by rods 29 to a rotatable lever 25 of a restoration assembly 4 which has a return spring 26 and a shock absorber 27, has an L-shaped pivotable hook 21 behind which a pin 12 of one of the two racks catches at the beginning of the opening. At the end of the closing, immobile stop 17 raises hook 21 to free pin 12. The same process occurs with the other rack to open the door in the other direction. The parts assemble in such a way that the door closure is not very thick and can be mounted directly inside a section of the door.

Description

La présente invention est relative à une ferme-porte à double action destiné notamment à assurer la fermeture automatique de portes pouvant s'ouvrir dans deux sens de rotation, ce ferme-porte comprenant un pivot dont la rotation est liée au mouvement de la porte et un dispositif de commande à levier tournant relié à une ressort de rappel et à un amortisseur.The present invention relates to a double action door closer intended in particular to ensure the automatic closing of doors which can open in two directions of rotation, this door closer comprising a pivot whose rotation is linked to the movement of the door and a rotary lever control device connected to a return spring and to a shock absorber.

Dans des ferme-porte à double action connus de ce type, tels que décrits dans le document DE-A 20 27 308, la liaison entre le pivot et le dispositif de commande à levier tournant est réalisée au moyen de cames. La réalisation de ces ferme-porte à double action nécessite l'usinage de cames de formes relativement complexes qui, pour avoir une durée de vie acceptable, doivent posséder des dimensions telles que les ferme-porte ne peuvent être placés dans les profilés étroits entrant dans la constitution de la porte.In known double action door closers of this type, as described in document DE-A 20 27 308, the connection between the pivot and the control device with rotary lever is produced by means of cams. The realization of these double action door closers requires the machining of cams of relatively complex shapes which, to have an acceptable lifetime, must have dimensions such that the door closers cannot be placed in the narrow profiles entering the constitution of the door.

Par ailleurs, le document DE-A-1 961 945 décrit un ferme-porte à double action ayant les caractéristiques énoncées dans le préambule de la revendication 1. Dans un tel dispositif, le pivot engrène avec deux crémaillères parallèles se faisant face, un ressort de rappel étant emprisonné entre des butées solidaires des deux crémaillères et un amortisseur étant disposé dans le prolongement du ressort. Ces ferme-porte présentent l'inconvénient qu'ils ont nécessairement une longueur importante. De plus, le ressort étant directement écrasé à ses deux extrémités par les butées, des crémaillères, un réglage de son écrasement est pratiquement irréalisable.Furthermore, document DE-A-1 961 945 describes a double action door closer having the characteristics set out in the preamble of claim 1. In such a device, the pivot meshes with two parallel racks facing each other, a spring return being trapped between stops integral with the two racks and a damper being arranged in the extension of the spring. These door closers have the disadvantage that they necessarily have a significant length. In addition, the spring being directly crushed at its two ends by the stops, racks, an adjustment of its crushing is practically impracticable.

L'invention a pour but de fournir un ferme-porte à double action ayant un encombrement réduit, à la fois étroit et de courte longueur, et facile à régler. A cet effet, elle a pour objet un ferme-porte à double action du type comportant un pivot dont la rotation est liée au mouvement de la porte et un dispositif de commande comprenant un amortisseur et un ressort de rappel, ledit pivot engrénant en permanence avec deux crémaillères parallèles se faisant face, caractérisé en ce qu'il est prévu des moyens de liaison sélectifs qui, pour chaque sens de rotation du pivot, solidarisent l'une des deux crémaillères avec le dispositif de commande pendant la course d'ouverture et désolidarisent cette crémaillère et ledit dispositif de commande à la fin de la course de fermeture.The object of the invention is to provide a double action door closer having a reduced size, both narrow and short in length, and easy to adjust. For this purpose, it relates to a double action door closer of the type comprising a pivot whose rotation is linked to the movement of the door and a control device comprising a damper and a return spring, said pivot permanently meshing with two parallel racks facing each other, characterized in that selective connecting means are provided which, for each direction of rotation of the pivot, secure one of the two racks with the control device during the opening stroke and separate this rack and said control device at the end of the closing stroke.

Grâce à la présence des moyens de liaison sélectifs, une des crémaillères est solidarisée avec le dispositif de commande dans un sens d'ouverture de la porte tandis que c'est l'autre crémaillère qui est solidarisée avec ce dispositif dans l'autre sens d'ouverture de la porte. Enoutre, dans le cas où l'on cherche à provoquer une fermeture de la porte à une vitesse supérieure à la vitesse de cetour préréglée assurée par le dispositif de commande, comme ce dernier se trouve solidarisé avec l'une des deux cremaillères, l'amortisseur du dispositif de commande peut jouer son côte et freiner le mouvement de cetour de la porte. L'épaisseur d'un tel ferme-porte peut facilement être rendue suffisamment faible pour permettre d'insérer le ferme-porte dans un profilé constitutif d'une porte.Thanks to the presence of the selective connecting means, one of the racks is secured to the control device in one direction of opening of the door while it is the other rack which is secured to this device in the other direction d door opening. Furthermore, in the case where it is sought to cause the door to close at a speed greater than the preset speed of the core provided by the control device, as the latter is secured to one of the two racks, the damper of the control device can play its side and slow down the movement of this around the door. The thickness of such a door closer can easily be made sufficiently small to allow the door closer to be inserted into a profile constituting a door.

Dans un mode de réalisation avantageux, les moyens de liaison sélectifs comprennent un levier oscillant porté par le dispositif de commande et présentant un crochet normalement situé sur les trajectoires d'une saillie de chaque crémaillère, le carter du ferme-porte comportant une butée attaquée par le levier oscillant en fin de course de fermeture pour écarter ce crochet desdites trajectoires.In an advantageous embodiment, the selective connection means comprise an oscillating lever carried by the control device and having a hook normally located on the paths of a projection of each rack, the housing of the door closer comprising a stop attacked by the lever oscillating at the end of the closing stroke to move this hook away from said trajectories.

En variante, les moyens de liaison sélectifs comprennent un élément mobile qui traverse avec jeu une tige longitudinale du dispositif de commande et des reliefs de chaque crémaillère qui déplacent latéralement l'élément mobile vers l'autre crémaillère pour solidariser cet élément avec cette autre crémaillère lorsque le pignon tourne dans le sens correspondant.Alternatively, the selective connecting means comprise a movable element which crosses with play a longitudinal rod of the control device and reliefs of each rack which laterally move the movable element towards the other rack to secure this element with this other rack when the pinion turns in the corresponding direction.

D'autres caractéristiques et avantages de l'invention ressortiront de la description qui va suivre, donnée à titre d'exemple non limitatif et en regard des dessins annexés, sur lesquels:

Le ferme-porte 1 représenté aux Fig. 1 à 4 comporte trois parties, à savoir, de gauche à droite en considérant la Fig. 1: un ensemble pivot-crémaillères 2, un ensemble de liaison 3 et un ensemble de commande 4. Chaque ensemble 2 à 4 est logé dans un boîtier 5 à 7 respectivement, ces boîtiers s'emboîtant les uns dans les autres pour constituer après vissage le carter du ferme-porte. Ce carter a une forme générale parallélépipédique dont l'épaisseur e (Fig. 2) est suffisamment faible pour loger le ferme-porte dans un profilé de porte.The door closer 1 shown in Figs. 1 to 4 has three parts, namely, from left to right considering FIG. 1: a pivot-rack assembly 2, a connection assembly 3 and a control assembly 4. Each assembly 2 to 4 is housed in a housing 5 to 7 respectively, these housings fitting into one another to constitute after screwing the door closer housing. This casing has a generally parallelepiped shape, the thickness e (Fig. 2) is small enough to accommodate the door closer in a door profile.

L'ensemble 2 comprend un pivot 8 d'axe vertical X-X librement rotatif dans le boîtier 5 mais axialement fixe. la partie intermédiaire de ce pivot forme un pignon 9 qui engrène avec deux crémaillères rectilignes 10 et 11 qui coulissent chacune contre une paroi latérale du boîtier 5 et qui forment l'image réfléchie l'une de l'autre. A une faible distance de son extrémité droite, chaque crémaillère porte un ergot horizontal 12 dirigé vers l'autre crémaillère. Au repos (Fig. 2), les ergots 12 se trouvent dans le prolongement l'un de l'autre, et les extrémités des crémaillères sont contenues dans deux plans verticaux perpendiculaires au plan de symétrie vertical P du ferme-porte.The assembly 2 comprises a pivot 8 of vertical axis XX freely rotatable in the housing 5 but axially fixed. the intermediate part of this pivot forms a pinion 9 which meshes with two rectilinear racks 10 and 11 which each slide against a side wall of the housing 5 and which form the reflected image one the other. At a short distance from its right end, each rack carries a horizontal pin 12 directed towards the other rack. At rest (Fig. 2), the pins 12 are in the extension of one another, and the ends of the racks are contained in two vertical planes perpendicular to the vertical plane of symmetry P of the door closer.

Le boîtier 6 de l'ensemble de liaison 3 présente un passage central 13 à section rectangulaire dans lequel coulisse un piston 14 parallélépipédique. La paroi supérieure du passage 13 comporte une rainure longitudinale 15 dans laquelle est fixée une lame souple 16. L'extrémité gauche de cette dernière est pliée vers le bas pour définir une courte butée 17, et son extrémité droite, qui possède une faculté de débattement vertical, présente un évidement arrondi 18. La lame 15 est fixée par des vis dans sa partie gauche, et une came rotative 19 à axe horizontal permet de régler la hauteur d'une partie de cette lame située entre ces vis et l'évidement 18.The housing 6 of the connection assembly 3 has a central passage 13 of rectangular section in which slides a piston 14 parallelepiped. The upper wall of the passage 13 has a longitudinal groove 15 in which a flexible blade 16 is fixed. The left end of the latter is folded down to define a short stop 17, and its right end, which has a capacity for movement vertical, has a rounded recess 18. The blade 15 is fixed by screws in its left part, and a rotary cam 19 with horizontal axis makes it possible to adjust the height of a part of this blade located between these screws and the recess 18 .

L'extrémité gauche du piston 14 porte un axe transversal 20 sur lequel est monté fou un levier 21 en L à deux bras. En position de repos (Fig. 1 ), un bras 22 est retenu par la butée 17 en position verticale; l'autre bras 23 fait saillie horizontalement vers la gauche hors du piston 14, et un crochet 24 dirigé vers le bas, qui forme l'extrémité de ce bras, est situé au-dessus du plan horizontal commun des ergots 12.The left end of the piston 14 carries a transverse axis 20 on which is mounted for a lever 21 in L with two arms. In the rest position (Fig. 1), an arm 22 is retained by the stop 17 in the vertical position; the other arm 23 projects horizontally to the left out of the piston 14, and a hook 24 directed downwards, which forms the end of this arm, is situated above the common horizontal plane of the pins 12.

L'ensemble de commande 4 comporte un levier rotatif 25 à axe horizontal dont un bras est relié à un ressort de compression réglable 26 et l'autre à un amortisseur hydraulique 27 également réglable, à piston 28. Cet ensemble 4 est classique; il ne sera donc pas décrit plus en détail et est représenté schématiquement. Deux bielles parallèles 29 sont articulées par une extrémité à un axe horizontal excentré 30 porté par le levier 25 et par l'autre extrémité à un axe horizontal 31 monté dans l'extrémité droite du piston 14. Les axes 20 et 31 et les ergots 12 sont parallèles et contenus dans le plan horizontal médian Q du ferme-porte. L'ensemble de commande 4 et le piston 14 forment le dispositif de commande du ferme-porte.The control assembly 4 comprises a rotary lever 25 with a horizontal axis, one arm of which is connected to an adjustable compression spring 26 and the other to a hydraulic damper 27 also adjustable, with piston 28. This assembly 4 is conventional; it will therefore not be described in more detail and is shown diagrammatically. Two parallel connecting rods 29 are articulated by one end to an eccentric horizontal axis 30 carried by the lever 25 and by the other end to a horizontal axis 31 mounted in the right end of the piston 14. The axes 20 and 31 and the pins 12 are parallel and contained in the median horizontal plane Q of the door closer. The control assembly 4 and the piston 14 form the control device for the door closer.

Le fonctionnement du ferme-porte double action 1 est le suivant:

  • Le carter du ferme-porte est par exemple fixé dans le profilé supérieur du cadre d'une porte, l'extrémité inférieure du pivot 8 étant fixée à la porte, suivant son axe de rotation. Toute autre disposition appropriée du ferme-porte peut également être envisagée.
The operation of the double action door closer 1 is as follows:
  • The door closer housing is for example fixed in the upper section of the frame of a door, the lower end of the pivot 8 being fixed to the door, along its axis of rotation. Any other suitable arrangement of the door closer can also be considered.

Sous l'effet de l'ouverture de la porte dans un premier sens, le pivot 8 tourne dans le sens horaire selon la flèche f (Fig. 4) en entraînant avec lui la crémaillère 10, qui coulisse vers la droite, et la crémaillère 11, qui coulisse en sens inverse. Sous l'effet de ce coulissement, la crémaillère 10 vient pousser directement le piston 14, qui coulisse également vers la droite. Les bielles 29 font alors tourner le levier 25 dans le sens horaire de la flèche g (Fig. 3), ce qui provoque d'une part la compression du ressort 26 et d'autre part le déplacement vers la droite sans entrave importante du piston amortisseur 28 dans son cylindre. Ce mouvement d'ouverture est limité par la butée de la crémaillère 11 contre la paroi d'extrémité gauche du boîtier 5.Under the effect of the opening of the door in a first direction, the pivot 8 rotates clockwise according to the arrow f (Fig. 4) by carrying with it the rack 10, which slides to the right, and the rack 11, which slides in the opposite direction. Under the effect of this sliding, the rack 10 directly pushes the piston 14, which also slides to the right. The connecting rods 29 then rotate the lever 25 in the clockwise direction of the arrow g (Fig. 3), which causes on the one hand the compression of the spring 26 and on the other hand the displacement to the right without significant hindrance of the piston shock absorber 28 in its cylinder. This opening movement is limited by the stop of the rack 11 against the left end wall of the housing 5.

Lorsque la crémaillère 10 vient en contact avec le piston 14, son ergot 12 se trouve juste derrière le crochet 24 du levier 21, au-dessous du bras 23 de celui-ci. Dès le début du coulissement du piston 14, le bras 22 du levier 21 s'écarte de la butée 17, ce qui laisse le levier 21 basculer vers la gauche sous l'effet de la gravité et amène le bras 23 sur l'ergot 12 de la crémaillère 10. Pendant la suite du coulissement, l'extrémité supérieure coudée 22a du bras 22 glisse le long de la lame 16 et assure que le crochet 24 ne peut plus se relever et reste en prise avec l'ergot 12.When the rack 10 comes into contact with the piston 14, its lug 12 is located just behind the hook 24 of the lever 21, below the arm 23 thereof. From the start of the sliding of the piston 14, the arm 22 of the lever 21 moves away from the stop 17, which leaves the lever 21 tilting to the left under the effect of gravity and brings the arm 23 onto the lug 12 of the rack 10. During the continuation of the sliding, the bent upper end 22a of the arm 22 slides along the blade 16 and ensures that the hook 24 can no longer rise and remains engaged with the lug 12.

Lors du relâchement de la porte, le ressort 26 tend à faire tourner le levier 25 dans le sens inverse de la flèche g, et cette rotation est freinée par l'amortisseur 27, la vitesse de retour étant réglable. La rotation du levier 25 dans le sens inverse de la flèche g provoque une poussée du piston 14 vers la gauche par les bielles 29; le piston 14 pousse à son tour vers la gauche la crémaillère 10, qui fait tourner le pivot 8 dans le sens inverse de la flèche f en assurant la fermeture de la porte. En fin de course de fermeture, l'extrémité coudée 22a du bras 22 du levier 21 traversant une ouverture de la butée 17, le bras 22 rencontre la butée 17 de sorte que le levier 21 pivote autour de son axe 20, le crochet 24 se relevant en libérant l'ergot 12 et reprenant sa position de départ comme représenté à la Fig. 1.When the door is released, the spring 26 tends to rotate the lever 25 in the opposite direction to the arrow g, and this rotation is braked by the damper 27, the return speed being adjustable. The rotation of the lever 25 in the opposite direction to the arrow g causes the piston 14 to be pushed to the left by the connecting rods 29; the piston 14 in turn pushes the rack 10 to the left, which rotates the pivot 8 in the opposite direction to the arrow f while ensuring the closing of the door. At the end of the closing stroke, the bent end 22a of the arm 22 of the lever 21 passing through an opening of the stop 17, the arm 22 meets the stop 17 so that the lever 21 pivots about its axis 20, the hook 24 raising by releasing the lug 12 and resuming its starting position as shown in FIG. 1.

L'ouverture de la porte dans l'autre sens entraîne le même fonctionnement du ferme-porte, mais sous l'effet de la crémaillère 11, son ergot 12 venant en prise sous le crochet 24.Opening the door in the other direction results in the same operation of the door closer, but under the effect of the rack 11, its lug 12 engaging under the hook 24.

Dans le cas où l'on cherche à provoquer une fermeture de la porte à une vitesse supérieure à la vitesse de retour préréglée assurée par l'ensemble de commande 4, c'est le pignon 8 qui devient moteur pour la course de fermeture, de sorte que la crémaillère considérée tend à s'écarter du piston 14. Cependant, l'accrochage de l'ergot 12 derrière le crochet 24 s'oppose à cette séparation, de sorte que le piston 14 est entraîné par la crémaillère et entraîne avec lui les bielles 29, le levier 25 et le piston amortisseur 28, qui freine le mouvement. L'amortisseur 27 peut comporter, comme connu, un dispositif limiteur de pression d'huile qui permet dans un tel cas une augmentation de la vitesse de déplacement de piston 28.In the case where it is sought to cause the door to close at a speed greater than the preset return speed provided by the control assembly 4, it is the pinion 8 which becomes the motor for the closing stroke, so that the rack considered tends to move away from the piston 14. However, the hooking of the lug 12 behind the hook 24 opposes this separation, so that the piston 14 is driven by the rack and drives with it the connecting rods 29, the lever 25 and the damping piston 28, which slows down the movement. The damper 27 may comprise, as known, an oil pressure limiting device which in such a case allows an increase in the speed of displacement of the piston 28.

Bien entendu, l'amortisseur 27 peut également être muni de moyens permettant l'accélération brusque du mouvement en fin de course de fermeture, afin de garantir la fermeture complète de la porte et, en particulier, l'enclenchement de la serrure de cette porte.Of course, the damper 27 can also be provided with means allowing the abrupt acceleration of the movement at the end of the closing stroke, in order to guarantee the complete closing of the door and, in particular, the engagement of the lock of this door. .

Comme on le voit, au cours du fonctionnement, le piston 14 est toujours solidaire de la crémaillère qui se déplace vers la droite, grâce au crochet 24, quel que soit le sens d'ouverture de la porte.As we can see, during the works ment, the piston 14 is always integral with the rack which moves to the right, thanks to the hook 24, whatever the direction of opening of the door.

La lame 16 peut servir non seulement de butée pour le levier 21 mais également de dispositif de maintien de la porte en position ouverte ou "arrêt de porte". En effet, lorsque la came 19 est rétractée, la lame 16 n'interfère pas avec la trajectoire d'une bille 32 portée par le piston 14. Cependant, si on le désire, on peut donner à la came 19 une position angulaire dans laquelle elle repousse vers le bas la partie droite de la lame 16. Dans ce cas, l'évidement 18 s'encliquette élastiquement en fin de course d'ouverture sur la bille 32, ce qui constitue l'arrêt de porte.The blade 16 can serve not only as a stop for the lever 21 but also as a device for holding the door in the open position or "door stop". In fact, when the cam 19 is retracted, the blade 16 does not interfere with the trajectory of a ball 32 carried by the piston 14. However, if desired, the cam 19 can be given an angular position in which it pushes down the right part of the blade 16. In this case, the recess 18 snaps resiliently at the end of the opening stroke on the ball 32, which constitutes the door stop.

Les Fig. 5 et 6 montrent une variante du dispositif de liaison sélectif entre les crémaillères 10 et 11 et le piston 14. Dans ce cas, le levier 21 est remplacé par une tige longitudinale 33 qui prolonge le piston 14 vers la gauche et est fixée rigidement à celui-ci. Une bille 34 traverse librement un trou 35 prévu à l'extrémité de la tige 33. Chaque crémaillère comporte à son extrémité droite un bloc 36 en saillie vers l'autre crémaillère, l'espacement entre les deux blocs étant inférieur au diamètre de la bille 34. L'extrémité gauche de chaque bloc 36 est creusée d'un évidement 37 à génératrices verticales et à fond 38 arrondi.Figs. 5 and 6 show a variant of the selective connection device between the racks 10 and 11 and the piston 14. In this case, the lever 21 is replaced by a longitudinal rod 33 which extends the piston 14 to the left and is rigidly fixed to that -this. A ball 34 freely passes through a hole 35 provided at the end of the rod 33. Each rack has at its right end a block 36 projecting towards the other rack, the spacing between the two blocks being less than the diameter of the ball 34. The left end of each block 36 is hollowed out by a recess 37 with vertical generatrices and with a rounded bottom 38.

Au repos, la bille 34 se trouve en regard des deux évidements 37, qui le retiennent dans le trou 35. Sous l'effet du déplacement vers la gauche de la crémaillère 11, cette bille 34 est poussée vers la crémaillère 10 par le fond 38 de i'évidement 37 de la crémaillère 11 et se loge au fond de l'évidement 37 de la crémaillère 10, ce qui assure la solidarisation du piston 14 avec la crémaillère 10 se déplaçant vers la droite. A part cette différence, le ferme-porte et son fonctionnement sont identiques à ce qui a été décrit plus haut en regard des Fig. 1 à 4.At rest, the ball 34 is opposite the two recesses 37, which hold it in the hole 35. Under the effect of the movement to the left of the rack 11, this ball 34 is pushed towards the rack 10 by the bottom 38 of the recess 37 of the rack 11 and is housed at the bottom of the recess 37 of the rack 10, which secures the piston 14 with the rack 10 moving to the right. Apart from this difference, the door closer and its operation are identical to what has been described above with reference to FIGS. 1 to 4.

En variante, la bille 34 peut être remplacée par un élément mobile de forme appropriée autre que sphérique permettant par exemple d'obtenir plus rapidément la solidarisation du piston avec la crémaillère en début d'ouverture.As a variant, the ball 34 can be replaced by a movable element of an appropriate shape other than a spherical one, for example making it possible more quickly to secure the piston with the rack at the start of opening.
