Abstract

The invention applies to a door closer. The device comprises a hydraulic chamber in which a piston is displaced when the door is turned by means of a pinion connected to one of the arms of the door closer. The device also comprises an injector via which the oil passes when the door recloses under the action of a spring. The injector has radial orifices, one of which can be closed by a valve associated with the piston and the other of which can be subjected to the action of a screw for setting the slow closing speed. The relative position between the injector tube and the piston determines the position of the door more or less near to the frame, from which it is to be displaced slowly. Longitudinal recesses offer a wider passage to the oil at the end of closing in order to overcome the resistance of the latch. Moreover, a locking element incorporated in the door closer makes it possible to keep the door open in a predetermined position. The invention is used in door closers. <IMAGE>

Description

La présente invention concerne un ferme-porte hydraulique perfectionné du point de vue de ses caractéristiques de forme et pouvant être avantageusement utilisé pour les fins auxquelles il est destiné.The present invention relates to a hydraulic door closer improved from the point of view of its shape characteristics and which can be advantageously used for the purposes for which it is intended.

Le ferme-porte qui fait l'objet de l'invention occupe peu de place et comprend plusieurs réglages parmi lesquels on peut mentionner entre autres : le réglage de la force de fermeture ; le réglage de la fermeture lente ou rapide en un endroit plus ou moins proche du b8- ti, et le réglage de la vitesse de fermeture lente.The door closer which is the subject of the invention occupies little space and comprises several adjustments among which one can mention among others: the adjustment of the closing force; adjusting the slow or fast closing in a place more or less close to the building, and adjusting the slow closing speed.

Le dispositif comprend une chambre hydraulique à l'intérieur de laquelle se trouve un piston se déplaçant quand on fait tourner la porte au moyen d'un pignon relié à l'un des bras de commande du ferme-porte . L'huile de la chambre passe d'un côté à l'autre du piston par l'intermédiaire d'une soupape associée à celui-ci.The device comprises a hydraulic chamber inside which is a piston which moves when the door is rotated by means of a pinion connected to one of the control arms of the door closer. The oil in the chamber passes from one side to the other of the piston via a valve associated with the latter.

Le dispositif comprend en outre un injecteur où passe l'huile après l'ouverture de la porte, lorsqu'elle se referme sous l'action d'un ressort. Ledit injecteur comprend un tube pourvu d'orifices radiaux l'un étant susceptible d'être fermé par la soupape et l'autre sur lequel agit une vis de réglage de la vitesse de fermeture lente. La position relative entre le tube injecteur et le piston règle la position de la porte plus ou moins proche du b8ti dans laquelle elle doit se déplacer lentement.The device further comprises an injector through which the oil passes after opening the door, when it closes under the action of a spring. Said injector comprises a tube provided with radial orifices one being capable of being closed by the valve and the other on which a screw for adjusting the slow closing speed acts. The relative position between the injector tube and the piston regulates the position of the door more or less close to the b8ti in which it must move slowly.

Une caractéristique de l'invention prévoit l'incorporation d'un dispositif permettant de fixer la porte dans une position préétablie et de préférence à 90°.A feature of the invention provides for the incorporation of a device for fixing the door in a predetermined position and preferably at 90 °.

Par contraste avec les autres dispositions dans lesquelles la fixation de la porte dans une position déterminée est obtenue au moyen d'un levier disposé sur l'un des bras, le ferme-porte qui fait l'objet de l'invention incorpore dans son corps général un élément de verrouillage coopérant avec une dent de blocage du piston de façon que sous l'action de cet élément de verrouillage sur le piston, la porte reste maintenue dans la position prédéterminée.In contrast to the other arrangements in which the fixing of the door in a determined position is obtained by means of a lever disposed on one of the arms, the door closer which is the subject of the invention incorporates into its body generally a locking element cooperating with a piston locking tooth so that under the action of this locking element on the piston, the door remains held in the predetermined position.

Selon une caractéristique de l'invention, aussi bien l'extrémité de l'élément de verrouillage que la dent de blocage ont leurs parois respectives inclinées de façon qu'en plus de rendre possible le verrouillage du piston dans la position qui détermine la fixation de la porte selon un angle d'ouverture prédéterminé, le dispositif permet en fermant légèrement la porte de débloquer le piston de l'élément de verrouillage.According to a characteristic of the invention, both the end of the locking element and the locking tooth have their respective walls inclined so that in addition to making it possible to lock the piston in the position which determines the fixing of the door at a predetermined opening angle, the device allows, by slightly closing the door, to unlock the piston of the locking element.

Selon une particularité de l'invention, il est prévu entre la dent de blocage et les dents où engrène le pignon de déplacement du piston une zone creuse où l'élément de verrouillage ne peut pas agir, ce qui rend possible un angle de pivotement plus important de la porte au-delà de sa position prédéterminée.According to a feature of the invention, there is provided between the blocking tooth and the teeth where the piston displacement pinion meshes a hollow zone where the locking element cannot act, which makes a more pivot angle possible. important of the door beyond its predetermined position.

L'invention sera mairtenant décrite plus en détail, avec référence aux dessins ci-annexés dans lesquels :

  • Les figures 1 et 2 sont une coupe du ferme-porte faisant l'objet de l'invention,
  • La figure 3 est une coupe du tube injecteur, et
  • La figure 4 représente un détail du piston et de l'élément de verrouillage.
The invention will now be described in more detail, with reference to the attached drawings in which:
  • Figures 1 and 2 are a section of the door closer forming the subject of the invention,
  • FIG. 3 is a section of the injector tube, and
  • Figure 4 shows a detail of the piston and the locking element.

Le ferme-porte comprend un corps général 1 fermé hermétiquement et à l'intérieur duquel est logé un piston 2 et une certaine quantité d'huile.The door closer comprises a general body 1 hermetically closed and inside which is housed a piston 2 and a certain amount of oil.

Sur le piston 2 agit un ressort 3 qui s'appuie entre ledit piston 2 et un écrou 4 monté sur la vis de tension 5. Le déplacement de la vis 5 détermine la variation de la force de fermeture de la porte.On the piston 2 acts a spring 3 which is supported between said piston 2 and a nut 4 mounted on the tensioning screw 5. The displacement of the screw 5 determines the variation of the closing force of the door.

Le piston 2 présente quelques dents 22 dans lesquelles engrène à la façon d'une crémaillère le pignon 6 relié à l'un des bras 7 de commande du ferme-porte, lequel bras 7 est articulé à l'autre bras 8 qui est par exemple celui qui est fixé sur le bâti de la porte. Le fait de faire tourner la porte détermine la rotation du pignon 6 et par là même le déplacement longitudinal du piston 2 d'un côté ou de l'autre de la chambre interne.The piston 2 has a few teeth 22 in which the pinion 6 connected to one of the arms 7 of the door closer control, in the manner of a rack, which arm 7 is articulated to the other arm 8 which is for example the one that is fixed on the door frame. Rotating the door determines the rotation of the pinion 6 and thereby the longitudinal displacement of the piston 2 on one side or the other of the internal chamber.

Dans le piston 2 est fixée une soupape 9 pourvue d'un ressort 10. La soupape 9 se déplace le long du tube injecteur 11 qui est pourvu d'un orifice axial 12 et d'orifices radiaux 13 et 14. Le tube injecteur 11 peut régler sa position par rapport au piston 2 grâce à la vis 15 qui en fait partie intégrante. Grâce à cette forme, on peut régler la position plus ou moins proche du bâti de la porte où la porte se ferme lentement puis passe à une seconde phase de fermeture rapide pour vaincre le loquet.In the piston 2 is fixed a valve 9 provided with a spring 10. The valve 9 moves along the injector tube 11 which is provided with an axial orifice 12 and radial orifices 13 and 14. The injector tube 11 can adjust its position relative to the piston 2 using the screw 15 which is an integral part thereof. Thanks to this shape, we can adjust the position more or less close to the door frame where the door closes slowly and then goes to a second phase of rapid closing to overcome the latch.

A l'intérieur de l'injecteur à vis 15 est logée la vis de réglage 16 agissant sur l'orifice radial 14 pour régler la vitesse de fermeture lente.Inside the screw injector 15 is housed the adjusting screw 16 acting on the radial orifice 14 to adjust the slow closing speed.

Quand on ouvre la porte, le piston 2 se déplace dans le sens de la flèche 17 à l'encontre du ressort 3. L'huile qui se trouvait dans la partie antérieure du piston 2 passe dans la partie postérieure à travers l'espace subsistant entre le piston 2 et la soupape 9.When the door is opened, the piston 2 moves in the direction of the arrow 17 against the spring 3. The oil which was in the front part of the piston 2 passes in the rear part through the remaining space between piston 2 and valve 9.

La fermeture de la porte est obtenue par l'action du ressort 3 qui pousse le piston 2 dans le sens de la flèche 18. Du fait de la pression propre de l'huile, la soupape 9 se déplace à l'encontre du ressort 10 en fermant le passage de communication. En conséquence, l'huile passe d'un côté à l'autre du piston 2 à travers les orifices radiaux 13 et 14 et l'orifice central 12et un mouvement de fermeture rapide se réalise jusqu'à ce que la soupape 9 obture l'orifice 13 ; à ce moment l'huile ne passe que par l'orifice radial 14, ce qui permet la fermeture lente dont la vitesse est réglée par la vis 16. Le réglage de la position dans laquelle la porte passe d'une fermeture rapide à une fermeture lente est déterminé par la vis 15 qui fait varier la position de l'orifice 13 par rapport à la soupape 9, ou ce qui revient au même, par rapport au piston 2.The door is closed by the action of the spring 3 which pushes the piston 2 in the direction of the arrow 18. Due to the oil pressure, the valve 9 moves against the spring 10 by closing the communication passage. Consequently, the oil passes from one side to the other of the piston 2 through the radial orifices 13 and 14 and the central orifice 12 and a rapid closing movement takes place until the valve 9 closes the orifice 13; at this time the oil only passes through the radial orifice 14, which allows slow closing, the speed of which is adjusted by screw 16. The adjustment of the position in which the door passes from a fast closing to a slow closing is determined by the screw 15 which varies the position of the orifice 13 relative to the valve 9, or what which is the same, compared to piston 2.

Le tube injecteur 11 comprend entre les deux orifices radiaux 14 et 13 des évidements longitudinaux 19.The injector tube 11 comprises between the two radial orifices 14 and 13 longitudinal recesses 19.

Lorsque la porte se ferme lentement du fait que le passage de l'huile ne s'effectue qu'à travers l'orifice radial 14, il arrive un moment où la soupape 9 est située sur les évidements 19 de manière que l'huile ne passe pas alors seulement par l'orifice 14 mais également par les évidements 19, ce qui détermine une fermeture rapide pour que la porte puisse vaincre le loquet de fermeture de ladite porte.When the door closes slowly because the passage of the oil only takes place through the radial orifice 14, there comes a point when the valve 9 is located on the recesses 19 so that the oil does not then not only passes through the orifice 14 but also through the recesses 19, which determines a rapid closing so that the door can overcome the closing latch of said door.

En fonction de la position de l'injecteur à vis, on ne règle pas seulement le moment où commence le mouvement de fermeture lente, mais également le moment où commence la fermeture rapide finale, que ce soit plus près ou plus loin du bâti, en fonction du type de loquet.Depending on the position of the screw injector, we not only regulate the moment when the slow closing movement begins, but also the moment when the final fast closing begins, whether it is closer or further from the frame, in depending on the type of latch.

Grâce au ferme-porte qui est l'objet de l'invention, il est possible d'effectuer divers types de réglages de façon simple et sans aucune spécialisation grâce aux éléments suivants :

  • a) la vis 16 qui constitue le dispositif de réglage de la seconde vitesse de fermeture ou fermeture lente ;
  • b) la vis 15 qui constitue le dispositif de réglage du coup final sur le loquet ;
  • c) la vis 5 par laquelle on agit pour régler la force du ressort par l'intermédiaire d'une clé de type "allen".
Thanks to the door closer which is the object of the invention, it is possible to carry out various types of adjustments in a simple manner and without any specialization thanks to the following elements:
  • a) the screw 16 which constitutes the device for adjusting the second closing speed or slow closing;
  • b) the screw 15 which constitutes the device for adjusting the final blow on the latch;
  • c) the screw 5 by which one acts to adjust the force of the spring by means of an "allen" type key.

Le corps général 1 comprend un logement pour un élément de verrouillage 20 qui est monté de manière à pouvoir agir sur le piston 2 par l'intermédiaire d'un ressort 21.The general body 1 comprises a housing for a locking element 20 which is mounted so as to be able to act on the piston 2 by means of a spring 21.

Le piston 2 comprend, en plus des dents 22 dans lesquelles engrène le pignon 6, une dent de blocage 23 avec laquelle coopère l'élément 20. Dans la position représentée sur la figure 4, l'élément de verrouillage 20 retient le piston 2 dans une position correspondant à la position d'ouverture de la porte de 90°, c'est-à-dire dans la position dans laquelle la porte reste constamment ouverte dans cette position préétablie.The piston 2 comprises, in addition to the teeth 22 in which meshes the pinion 6, a locking tooth 23 with which the element 20 cooperates. In the position shown in FIG. 4, the locking element 20 retains the piston 2 in a position corresponding to the open position of the door. 90 °, that is to say in the position in which the door remains constantly open in this preset position.

Selon une particularité de l'invention, la dent de blocage 23 et l'extrémité de l'élément 20 sont pourvues de parois inclinées 24 qui sont complémentaires et permettent l'action de déblocage ou de blocage de la position fixe d'ouverture.According to a feature of the invention, the locking tooth 23 and the end of the element 20 are provided with inclined walls 24 which are complementary and allow the action of unlocking or blocking the fixed open position.

Par exemple, si on désire éliminer la position d'ouverture fixe, une petite rotation de fermeture de la porte provoque un déplacement longitudinal du piston 2 dans la direction de la flèche 25, et le patinage de la paroi inclinée 24 de la dent sur la paroi inclinée 24 de l'élément 20, lequel se déplace à l'encontre du ressort 21, annulant ainsi le verrouillage de la porte. Quand on ouvre à nouveau la porte vers la position prédéterminée, on provoque le verrouillage du piston 2 par l'élément 20.For example, if one wishes to eliminate the fixed opening position, a small closing rotation of the door causes a longitudinal displacement of the piston 2 in the direction of the arrow 25, and the slippage of the inclined wall 24 of the tooth on the inclined wall 24 of the element 20, which moves against the spring 21, thereby canceling the locking of the door. When the door is opened again to the predetermined position, the piston 2 is locked by the element 20.

Selon une autre caractéristique de l'invention, il est prévu entre les dents 22 et la dent de blocage 23 une zone libre 26 où n'agit pas l'élément de verrouillage 20. Cette zone 26 permet de faire pivoter la porte sur un angle supérieur à celui qui est prédéterminé.According to another characteristic of the invention, there is provided between the teeth 22 and the locking tooth 23 a free area 26 where the locking element 20 does not act. This area 26 allows the door to pivot by an angle greater than that which is predetermined.

La porte est normalement réglée sur une position d'ouverture de 90°, mais toute autre position fixe plus ouverte ou plus fermée peut être choisie avec les bras articulés.The door is normally set to an opening position of 90 °, but any other more open or closed fixed position can be chosen with the articulated arms.

Le pivotement de la porte sur un angle inférieur à celui de 90° qui a été préétabli, ou de tout autre angle, peut être réalisé sans aucun problème du fait que l'élément de verrouillage 20 n'agit pas sur le piston 2.The pivoting of the door to an angle less than that of 90 ° which has been preset, or of any other angle, can be carried out without any problem since the locking element 20 does not act on the piston 2.

Ayant ainsi décrit la nature de l'invention ainsi que sa réalisation sur le plan industriel, il suffit d'ajouter qu'il est possible d'apporter des modifications de forme, de matériaux et de disposition à l'ensemble ou aux parties constituantes sans sortir du champ d'application de l'invention, dans la mesure où ces modifications ne supposent pas des changements essentiels apportés à ladite invention.Having thus described the nature of the invention as well as its implementation on the industrial level, it suffices to add that it is possible to make changes in shape, materials and layout to the assembly or to the constituent parts without departing from the scope of the invention, insofar as these changes do not imply essential changes to the said invention.
