Description

La présente invention se rapporte à un ferme-porte à amortissement hydraulique, du type comprenant un boítier pouvant être positionné dans l'ouvrant ou le dormant d'une porte et provoquant le retour de la porte vers une position de fermeture, ainsi qu'au procédé de fabrication de ce ferme porte.The present invention relates to a door closers with hydraulic damping, type comprising a housing that can be positioned in the opening or the frame of a door and causing the door to return to a closed position, as well as to the manufacturing process of this door farm.

Elle concerne plus particulièrement un ferme-porte dans le boítier duquel est monté au moins un arbre d'entraínement mobile en rotation selon un axe orienté selon une première direction et faisant saillie à l'extérieur dudit boítier, ainsi que deux galets également mobiles chacun en rotation selon un axe orienté selon ladite première direction, lesdits galets coopérant chacun d'une part avec ledit arbre et d'autre part respectivement avec un piston mobile en translation selon un axe orienté selon une deuxième direction sensiblement perpendiculaire à la première direction, un premier piston étant soumis à l'action de moyens de rappel et un deuxième piston séparant deux chambres hydrauliques reliées par un système de conduit(s).It relates more particularly to a door closer in the housing of which is mounted at least one drive shaft movable in rotation along an axis oriented according to a first direction and protruding outside said housing, and two pebbles also movable each in rotation along an axis oriented in said first direction, said rollers each cooperating on the one hand with said shaft and on the other hand respectively with a piston movable in translation along an axis oriented in a second direction substantially perpendicular to the first direction, a first piston being subjected to the action of return means and a second piston separating two hydraulic chambers connected by a system of conduit (s).

L'art antérieur connaít à ce titre la demande de brevet européen N° EP 146 693 qui porte sur un ferme-porte dont le boítier est fixé contre la porte, dans sa partie supérieure et dont l'arbre d'entraínement est relié à un bras d'actionnement pivotant, l'extrémité distale de ce bras coulissant dans un moyen de guidage fixé contre le dormant.The prior art is known in this respect the European patent application No. EP 146 693 which door on a door closer whose housing is fixed against the door, in its upper part and whose drive shaft is connected to a pivoting actuating arm, the distal end of this sliding arm in a guide means fixed against the frame.

L'art antérieur connaít par ailleurs la demande de brevet britannique N° GB 1 128 751 qui porte sur un ferme-porte dont le boítier est positionné dans un renfoncement, dans le linteau au-dessus de la porte et dont les moyens de rappel sont constitués d'au moins deux ensembles (empilements) de rondelles Belleville positionnés côte à côte, afin de permettre de réaliser une force de rappel présentant différentes valeurs à différents états d'ouverture de la porte, comme expliqué dans ce document.The prior art also known from British Patent Application No. GB 1,128 751 which concerns a door closer whose housing is positioned in a recess, in the lintel above the door and whose return means consist of at least two sets (stacks) of Belleville washers positioned side by side in order to make it possible to make a restoring force presenting different values to different states opening of the door, as explained in this document.

Dans ce document les moyens de rappel présentent une largeur telle qu'il est impossible d'envisager de dissimuler complètement le boítier dans le dormant ou a fortiori dans la porte.In this document the return means have a width such that it is impossible to consider completely conceal the housing in the frame or a fortiori in the door.

Il apparaít ainsi que jusqu'à maintenant, il était difficile de disposer la totalité du ferme-porte à l'intérieur de l'ouvrant ou du dormant de la porte, soit en raison de la présence d'un bras de levier ou d'un bras coulissant à l'extérieur du boítier, soit en raison de la largeur des moyens de rappel utilisés. It thus appears that until now, it was difficult to dispose of the entire door closer to the door opening or door frame, either because of the presence of a lever arm or a sliding arm outside the housing, either due to the width of the return means used.

La présente invention entend remédier aux inconvénients de l'art antérieur en proposant un ferme-porte compact et suffisamment étroit pour pouvoir être dissimulé dans l'ouvrant ou le dormant, sans qu'il soit nécessaire de prévoir un bras de levier.The present invention intends to overcome the drawbacks of the prior art by a compact door closer that is small enough to conceal the opening or the frame, without it being necessary to provide a lever arm.

Ainsi, le ferme-porte dans sa totalité est inaccessible aux actes de malveillance ou de vandalisme.Thus, the door closer in its entirety is inaccessible to malicious acts or vandalism.

En outre, la présente invention entend permettre une fermeture forcée selon les deux sens de fermeture selon un angle pouvant aller jusqu'à +180°, -180° ou ±180° par rapport à la position fermée.In addition, the present invention intends to allow a forced closure according to the two directions of closure at an angle of up to + 180 °, -180 ° or ± 180 ° compared to the closed position.

La présente invention se rapporte ainsi dans son acception la plus large à un ferme-porte selon la revendication 1. Dans ce ferme-porte lesdits moyens de rappel comprennent une pluralité de rondelles Belleville identiques ou différentes montées sensiblement coaxialement selon ladite deuxième direction, c'est-à-dire, la direction de l'axe du piston mobile en translation.The present invention thus relates in its broadest sense to a door closer according to claim 1. In this door closer said return means comprise a plurality of identical or different Belleville washers mounted substantially coaxially along said second direction, i.e., the direction of the piston axis mobile in translation.

Par « moyens de rappel", on entend des moyens qui sont destinés à exercer la force qui va rappeler, c'est-à-dire ramener, la porte dans sa position de fermeture."Reminder means" means means intended to exert force who will recall, that is to say, bring back the door in its closed position.

La pluralité de rondelles forme un ensemble unique : elles sont toutes coaxiales et positionnées de manière à ce que leur axe soit perpendiculaire à l'axe de l'arbre d'entraínement.The plurality of washers form a single set: they are all coaxial and positioned so that their axis is perpendicular to the axis of the tree drive.

Selon un mode de réalisation de l'invention, lesdites rondelles Belleville sont montées sur un tube de guidage central.According to one embodiment of the invention, said Belleville washers are mounted on a central guide tube.

Au moins une partie desdites rondelles Belleville adjacentes sont montées tête-bêche, c'est-à-dire avec le diamètre intérieur d'une rondelle orienté dans le sens opposé par rapport au diamètre intérieur d'au moins une rondelle adjacente et/ou au moins une partie desdites rondelles Belleville adjacentes sont montées sensiblement parallèles, c'est-à-dire avec le diamètre intérieur d'une rondelle orienté dans le même sens par rapport au diamètre intérieur d'au moins une rondelle adjacente.At least a portion of said adjacent Belleville washers are mounted upside down, that is with the inner diameter of a washer oriented in the opposite direction by ratio to the inside diameter of at least one adjacent washer and / or at least a portion adjacent Belleville washers are mounted substantially parallel, i.e. with the inner diameter of a washer oriented in the same direction relative to the diameter inside of at least one adjacent washer.

Lesdites rondelles Belleville présentent, de préférence, un diamètre intérieur identique et/ou un diamètre extérieur identique.Said Belleville washers preferably have an inside diameter identical and / or an identical outside diameter.

Lesdits moyens de rappel provoquent, de préférence, le retour de la porte vers une position de fermeture quel que soit le sens d'ouverture préalable.Said biasing means preferably cause the door to be returned to a closing position regardless of the direction of opening.

La présente invention se rapporte également à une porte dans l'ouvrant ou le dormant de laquelle est positionné un ferme-porte à amortissement hydraulique selon l'invention, ledit ferme-porte étant du type comprenant un boítier dans lequel est monté au moins un arbre d'entraínement mobile en rotation faisant saillie à l'extérieur dudit boítier, ledit arbre d'entraínement étant relié par cette partie faisant saillie respectivement audit dormant ou audit ouvrant de la porte.The present invention also relates to a door in the opening or the frame of which is positioned a hydraulic damping door closer according to the invention, said door closer being of the type comprising a housing in which is mounted to the less a drive shaft movable in rotation projecting outside said housing, said drive shaft being connected by this protruding portion respectively to said dormant or opening of the door.

Selon un mode préféré de réalisation de l'invention, ledit boítier est caché à l'intérieur dudit ouvrant ou dudit dormant.According to a preferred embodiment of the invention, said housing is hidden at inside said opening or said frame.

La présente invention se rapporte également à un procédé de fabrication d'un ferme-porte à amortissement hydraulique, du type comprenant un boítier dans lequel est monté au moins un arbre d'entraínement mobile en rotation selon un axe orienté selon une première direction et faisant saillie à l'extérieur dudit boítier, ainsi que deux galets également mobiles chacun en rotation selon un axe orienté selon ladite première direction, lesdits galets coopérant chacun d'une part avec ledit arbre et d'autre part respectivement avec un piston mobile en translation selon un axe orienté selon une deuxième direction sensiblement perpendiculaire à la première direction, un premier piston étant soumis à l'action de moyens de rappel et un deuxième piston séparant deux chambres hydrauliques reliées par un système de conduit(s), selon lequel on réalise lesdits moyens de rappel en sélectionnant une pluralité de rondelles Belleville identiques ou différentes et en montant sensiblement coaxialement lesdites rondelles Belleville selon ladite deuxième direction, ladite sélection et ledit montage étant opérés en fonction de la force souhaitée qui est exercée par lesdits moyens de rappel sur ledit premier piston.The present invention also relates to a method of manufacturing a door closers with hydraulic damping, of the type comprising a housing in which is mounted at least one drive shaft movable in rotation along an axis oriented according to a first direction and protruding outside said housing, and two pebbles also movable each in rotation along an axis oriented in said first direction, said rollers each cooperating on the one hand with said shaft and on the other hand respectively with a piston movable in translation along an axis oriented in a second direction substantially perpendicular to the first direction, a first piston being subjected to the action of return means and a second piston separating two hydraulic chambers connected by a conduit system (s), according to which said return means is selecting a plurality of identical or different Belleville washers and ascending substantially coaxially said Belleville washers in said second direction, said selection and said mounting being operated according to the desired force which is exerted by said biasing means on said first piston.

Les rondelles Belleville adjacentes sont, de préférence, montées tête-bêche ou parallèles les unes par rapport aux autres.Adjacent Belleville washers are preferably mounted upside down or parallel to each other.

La sélection et le montage desdites rondelles Belleville est, de préférence, opéré en fonction au moins de la force du ferme-porte désirée.The selection and assembly of said Belleville washers is preferably carried out in function at least the strength of the desired door closer.

Selon une variante de l'invention, lesdites rondelles Belleville sont montées précontraintes à l'intérieur dudit boítier.According to a variant of the invention, said Belleville washers are mounted prestressing inside said housing.

Pour la mise en oeuvre du procédé, il peut en outre être nécessaire de définir un profil de came particulier pour l'arbre d'entraínement.For the implementation of the method, it may further be necessary to define a particular cam profile for the drive shaft.

La présente invention se rapporte également à une utilisation de moyens de rappel comprenant une pluralité de rondelles Belleville identiques ou différentes pour un ferme-porte à amortissement hydraulique.The present invention also relates to a use of recall means comprising a plurality of identical or different Belleville washers for a door closer with hydraulic damping.

Ainsi, le ferme-porte selon l'invention, à force réglable, est encastrable dans un profil bois, aluminium, acier ou autre, soit dans le linteau au-dessus de la porte, soit dans la traverse haute d'ouvrant de la porte, soit dans la traverse basse (plinthe) de la porte. Thus, the door closer according to the invention, with adjustable force, is recessed into a profile wood, aluminum, steel or other, either in the lintel above the door, or in the through the door opening, either in the bottom rail (skirting) of the door.

Le ferme-porte selon l'invention ne peut pas être disposé en pivot de sol, c'est-à-dire avec le boítier intégré dans le sol car il ne présente pas une largeur suffisante pour réaliser un maintien adéquat.The door closer according to the invention can not be arranged in a floor pivot, that is to say with the integrated housing in the ground because it does not have a sufficient width for achieve adequate support.

De plus, une fois installé, il est complètement invisible pour éviter tout acte de vandalisme. La force de rappel de la porte dans sa position de fermeture étant directement transmise par l'arbre principal, le ferme-porte ne comporte pas de bras de levier ou de bras coulissant qui dépasse soit de la porte soit du linteau.Moreover, once installed, it is completely invisible to avoid any act of vandalism. The return force of the door in its closed position being directly transmitted by the main shaft, the door closer does not have a lever or arm sliding that exceeds either the door or the lintel.

Le ferme-porte selon l'invention est conçu pour pouvoir être installé soit au moment de l'installation de la porte dont il engendre la fermeture, soit pour pouvoir être installé après l'installation de la porte afin de permettre la fermeture d'une porte qui ne comportait pas auparavant de ferme-porte ou qui comportait un ferme-porte défaillant.The door closer according to the invention is designed to be installed either at the moment of the installation of the door which it causes the closure, that is to be installed after the door has been installed to allow the closing of a door that does not did not previously have a door closer or had a failing door closer.

Il présente une très grande résistante à l'usage et est moins onéreux à fabriquer que les ferme-porte de l'art antérieur. Il est en outre plus facile à fabriquer et surtout plus facile à adapter en fonction de la force de fermeture souhaitée.It is very resistant to use and is less expensive to manufacture than the door closers of the prior art. It is also easier to manufacture and above all easier to be adapted according to the desired closing force.

La force du ferme-porte est réglable de 3 à 5, voire de 2 à 5, (au sens de la norme EN1154) par l'intermédiaire d'une vis de réglage sur laquelle il est possible d'agir, par exemple avec une clef six pans.The force of the door closer can be adjusted from 3 to 5 or even from 2 to 5 (according to the standard EN1154) by means of a setting screw on which it is possible to act, by example with a hex key.

La vitesse de fermeture est réglable sur deux plages : de 0 à 25° pour la fin de course ; de 0° à 180° sur toute la plage de fermeture.The closing speed is adjustable over two ranges: from 0 to 25 ° for the end of race; from 0 ° to 180 ° over the entire closing range.

La figure 1 représente une vue en perspective d'une première variante de réalisation du ferme-porte à amortissement hydraulique selon l'invention.FIG. 1 represents a perspective view of a first variant embodiment hydraulic damping door closer according to the invention.

Ce ferme-porte (1) comprend un boítier constitué d'un carter (2) sensiblement parallélépipédique et d'un tube cylindrique (3) présentant un axe, le carter et le tube cylindrique étant disposés de telle manière que le tube cylindrique rentre dans le carter par une face de ce dernier, l'axe du tube cylindrique étant positionnée sensiblement perpendiculairement à ladite face du carter.This door closer (1) comprises a housing consisting of a casing (2) substantially parallelepiped and a cylindrical tube (3) having an axis, the housing and the tube cylindrical being arranged in such a way that the cylindrical tube enters the housing by a face of the latter, the axis of the cylindrical tube being positioned substantially perpendicular to said housing face.

Un arbre d'entraínement (4) mobile en rotation est monté dans le boítier du ferme-porte (1) et plus précisément dans le carter (2) en faisant saillie à l'extérieur dudit boítier, de telle manière que l'axe de l'arbre est orienté selon une première direction A.A drive shaft (4) movable in rotation is mounted in the housing of the door closer (1) and more precisely in the housing (2) protruding outside said housing, such that the axis of the shaft is oriented in a first direction A.

L'axe du tube cylindrique (3) est orienté selon une deuxième direction A' qui est perpendiculaire et sécante à la première direction A.The axis of the cylindrical tube (3) is oriented in a second direction A 'which is perpendicular and secant to the first direction A.

Comme on peut le voir sur la figure 2, le carter (2) comporte également deux galets (5, 6) tubulaires mobiles chacun en rotation selon un axe orienté parallèlement à ladite première direction A.As can be seen in FIG. 2, the casing (2) also comprises two tubular rollers (5, 6) each movable in rotation along an axis oriented parallel to said first direction A.

Lesdits galets (5, 6) coopèrent chacun d'une part avec ledit arbre (4) et d'autre part respectivement avec un piston (7, 8) mobile en translation selon un axe orienté selon la deuxième direction A'. Un premier piston (7) est soumis à l'action de moyens de rappel et un deuxième piston (8) sépare deux chambres hydrauliques (9, 9') reliées par un système de conduits (18).Said rollers (5, 6) each cooperate on the one hand with said shaft (4) and on the other hand respectively with a piston (7, 8) movable in translation along an axis oriented according to the second direction A '. A first piston (7) is subjected to the action of return means and a second piston (8) separates two hydraulic chambers (9, 9 ') connected by a system ducts (18).

Dans l'exemple illustré sur les figures 1 à 6, le boítier présente une longueur hors tout d'environ 35 cm ; le carter (2) présente une largeur d'environ 3,5 cm et une hauteur d'environ 4,2 cm et le tube cylindrique (3) présente un diamètre extérieur d'environ 3,5 cm.In the example illustrated in Figures 1 to 6, the housing has a length off all about 35 cm; the housing (2) has a width of about 3.5 cm and a height about 4.2 cm and the cylindrical tube (3) has an outside diameter of about 3.5 cm.

Selon l'invention, lesdits moyens de rappel comprennent une pluralité de rondelles Belleville (10) identiques ou différentes montées sensiblement coaxialement selon ladite deuxième direction A'.According to the invention, said return means comprise a plurality of washers Belleville (10) identical or different mounted substantially coaxially according to said second direction A '.

Pour faciliter le positionnement des rondelles de manière à ce qu'elles soient exactement parallaxes les unes avec les autres et avec l'axe du tube cylindrique (3), lesdites rondelles Belleville (10) sont montées sur un tube de guidage central (11) dont l'axe est confondu avec l'axe du tube cylindrique (3).To facilitate the positioning of the washers so that they are exactly parallaxes with each other and with the axis of the cylindrical tube (3), said Belleville washers (10) are mounted on a central guide tube (11) whose the axis coincides with the axis of the cylindrical tube (3).

Dans un exemple de réalisation on a disposé 100 rondelles identiques en acier, chacune de diamètre extérieur égal à 32 mm, de diamètre intérieur égal à 16 mm, pour une hauteur de 2 mm, toutes en opposition simple, c'est-à-dire avec les concavités des rondelles adjacentes en opposition.In an exemplary embodiment, 100 identical washers made of steel were each with an outer diameter of 32 mm and an inner diameter of 16 mm height of 2 mm, all in simple opposition, that is to say with the concavities of adjacent washers in opposition.

Cette disposition a permis d'obtenir une course du piston (7) de l'ordre de 10 cm.This arrangement has made it possible to obtain a piston stroke (7) of the order of 10 cm.

En utilisant ces rondelles Belleville pour la restitution du couple de fermeture sur la porte, on obtient, à dimensions de boítier équivalentes, un couple plus grand qu'avec un (ou plusieurs) ressort(s) hélicoïdal(aux) et il n'est plus nécessaire d'utiliser un bras de levier ou un bras coulissant. En effet, avec un ferme-porte tel que celui illustré sur les figures 1 à 6, présentant les dimensions exposées ci-dessus, le moment de fermeture délivré est de l'ordre de 50 Nm, alors qu'avec un ferme-porte présentant des dimensions équivalentes mais muni d'un ressort hélicoïdal de compression, le moment de fermeture délivré est environ deux fois moins élevé, soit de l'ordre de 25 Nm.By using these Belleville washers for the restitution of the closing torque on the door, we get, equivalent to housing dimensions, a larger torque than with a (or more) helical spring (s) and it is no longer necessary to use an arm of lever or a sliding arm. Indeed, with a door closer such as the one shown on the Figures 1 to 6, having the dimensions set out above, the closing moment delivered is of the order of 50 Nm, whereas with a door closer with dimensions equivalent but with a compression coil spring, the closing moment delivered is about half of the order of 25 Nm.

En outre, la longévité des moyens de rappel est augmentée car les tests menés ont montré que des moyens de rappel composés de rondelles Belleville peuvent atteindre le million de cycles sans perte notable de caractéristiques, alors qu'un ressort hélicoïdal de dimension équivalente ne dépasse pas 500 mille cycles sans perte notable de caractéristiques.In addition, the durability of the return means is increased because the tests conducted have have shown that return means consisting of Belleville washers can reach the million cycles without significant loss of characteristics, whereas a coil spring of equivalent dimension does not exceed 500 thousand cycles without significant loss of characteristics.

Un autre intérêt de l'usage des rondelles Belleville réside dans le fait que l'on évite ainsi tout effet de rotation des moyens de rappel sur eux-même, tel qu'il se produisait auparavant avec les ressorts. Cette rotation du ressort entraínait souvent une rotation du piston associé et par conséquent une perte d'efficacité.Another advantage of the use of Belleville washers lies in the fact that we avoid thus any effect of rotation of the return means on themselves, as it occurred previously with the springs. This rotation of the spring often led to a rotation of the associated piston and consequently a loss of efficiency.

Une rondelle Belleville, encore appelée « rondelle ressort » est, d'une manière connue une rondelle de forme annulaire, généralement en métal ou en alliage métallique, présentant un diamètre intérieur et un diamètre extérieur, le diamètre intérieur étant inférieur au diamètre extérieur, la forme annulaire n'étant pas plate mais conique. Une rondelle Belleville s'étend ainsi sur une hauteur supérieure à l'épaisseur de la matière constituant l'anneau.A Belleville washer, also called "spring washer" is, in a way known an annular washer, usually made of metal or metal alloy, having an inner diameter and an outer diameter, the inner diameter being less than the outside diameter, the annular shape being not flat but conical. A Belleville washer extends over a height greater than the thickness of the material constituting the ring.

La hauteur d'une rondelle Belleville dépend de la force de compression à laquelle elle est soumise. Cette compression est habituellement orientée parallèlement à l'axe de la forme annulaire. Généralement, une rondelle Belleville est fabriquée dans un matériau élastique et elle reprend sa hauteur initiale lorsqu'elle n'est plus soumise à une force de compression.The height of a Belleville washer depends on the compressive force at which she is submissive. This compression is usually oriented parallel to the axis of the annular form. Generally, a Belleville washer is made of a material elastic and it resumes its initial height when it is no longer subject to a force of compression.

Ainsi, il est possible de monter toutes les rondelles Belleville (10) adjacentes en opposition simple ou tête-bêche, comme illustré sur la figure 2, c'est-à-dire de telle manière que le diamètre intérieur d'une rondelle est orienté dans le sens opposé par rapport au diamètre intérieur de chaque rondelle adjacente.Thus, it is possible to mount all adjacent Belleville washers (10) in simple opposition or head-to-tail, as illustrated in Figure 2, that is to say, such the inner diameter of a washer is oriented in the opposite direction to to the inside diameter of each adjacent washer.

Toutefois, il est également possible de monter toutes les rondelles Belleville (10) adjacentes parallèles, c'est-à-dire avec le diamètre intérieur d'une rondelle orienté dans le même sens par rapport au diamètre intérieur d'au moins une rondelle adjacente.However, it is also possible to mount all Belleville washers (10) adjacent parallels, that is to say with the inside diameter of a washer oriented in the same direction relative to the inside diameter of at least one adjacent washer.

Il est également possible de monter dans un tube cylindrique (3), des rondelles Belleville (10) adjacentes tête-bêche et des rondelles Belleville (10) adjacentes parallèles.It is also possible to mount in a cylindrical tube (3), washers Belleville (10) adjacent head-to-tail and Belleville washers (10) adjacent parallel.

Pour faciliter le montage, les rondelles qui ont été choisies avaient toutes le même diamètre intérieur et le même diamètre extérieur, la même épaisseur et la même hauteur au repos.To facilitate assembly, the washers that were selected all had the same inside diameter and the same outside diameter, the same thickness and the same height at rest.

Toutefois, il est possible de choisir des rondelles qui ont toutes le même diamètre intérieur mais dont certaines ont un diamètre extérieur différent, ainsi qu'éventuellement une épaisseur et/ou une hauteur différente.However, it is possible to choose washers that all have the same diameter interior but some of which have a different outside diameter, as well as possibly a different thickness and / or height.

Toutes les configurations associant les différentes caractéristiques d'agencement des rondelles Belleville ci-dessus semblent possibles.All configurations associating different layout features Belleville washers above seem possible.

Comme on peut le voir sur la figure 2, les galets (5, 6) sont montés respectivement chacun sur une goupille cylindrique (13, 14), par l'intermédiaire, pour le galet (5) d'aiguilles (12) montées entre celui-ci et la goupille cylindrique (13).As can be seen in FIG. 2, the rollers (5, 6) are respectively mounted each on a cylindrical pin (13, 14), via, for the roller (5) of needles (12) mounted between it and the cylindrical pin (13).

Le diamètre extérieur des galets (5, 6) est constant sur toute leur longueur, mais l'arbre (4) présente une came constituée par une augmentation de son rayon de courbure extérieur sensiblement sur toute la hauteur du profil de came en contact avec les galets (5, 6). The outer diameter of the rollers (5, 6) is constant over their entire length, but the shaft (4) has a cam constituted by an increase in its radius of curvature outside substantially the full height of the cam profile in contact with the rollers (5, 6).

Pour faciliter la rotation de l'arbre (4) sur son axe, ce dernier est de préférence monté à une extrémité supérieure sur une douille à aiguille tubulaire (24) et à une extrémité inférieure sur un roulement (20), par exemple un roulement à billes.To facilitate the rotation of the shaft (4) on its axis, the latter is preferably mounted at an upper end on a tubular needle socket (24) and at one end lower on a bearing (20), for example a ball bearing.

L'extrémité distale du boítier, c'est-à-dire l'extrémité la plus éloignée de l'arbre (4), est munie d'un filetage sur la face intérieure du tube cylindrique (3). Ce filetage est destiné à permettre de visser un bouchon distal (21) présentant sur sa surface extérieure un filetage complémentaire. Une rondelle (22) en acier trempée est positionnée à chaque extrémité des moyens de rappel pour éviter une usure prématurée de la surface de contact d'une part du bouchon distal (21) et d'autre part du piston (7).The distal end of the housing, that is to say the end furthest from the shaft (4) is provided with a thread on the inner face of the cylindrical tube (3). This threading is intended to allow screwing a distal plug (21) having on its outer surface a complementary thread. A hardened steel washer (22) is positioned at each end of the return means to prevent premature wear of the contact surface on the one hand the distal plug (21) and on the other hand the piston (7).

La position du bouchon distal (21) vis-à-vis du tube cylindrique (3) permet de réaliser une précontrainte réglable des rondelles Belleville (10).The position of the distal plug (21) vis-à-vis the cylindrical tube (3) allows carry out an adjustable preload of the Belleville washers (10).

Le piston (7) est muni à sa périphérie d'un joint torique (23) en contact avec la face intérieure du carter (2), afin d'empêcher que l'huile présente dans la chambre (9) ne se propage dans le tube cylindrique (3). Le piston (7) est ainsi en contact, à une première extrémité par rapport à la direction A' avec une rondelle (22) et à l'autre extrémité avec le galet (5).The piston (7) is provided at its periphery with an O-ring (23) in contact with the face inside the housing (2) to prevent the oil in the chamber (9) from spread in the cylindrical tube (3). The piston (7) is thus in contact, at a first end with respect to the direction A 'with a washer (22) and at the other end with the roller (5).

Un joint torique (19) est également positionné autour de l'arbre (4), au niveau du chapeau supérieur (25) qui retient la partie interne de l'arbre (4) dans le carter (2).An O-ring (19) is also positioned around the shaft (4), at the upper cap (25) which holds the inner part of the shaft (4) in the housing (2).

L'extrémité proximale du boítier, c'est-à-dire l'extrémité la plus proche de l'arbre (4), est également munie d'un filetage sur la face intérieure du carter (2). Ce filetage est destiné à permettre de visser un bouchon proximal (26) présentant sur sa surface extérieure un filetage complémentaire.The proximal end of the housing, that is to say the end closest to the shaft (4) is also provided with a thread on the inner face of the housing (2). This thread is intended to allow screwing a proximal plug (26) having on its outer surface a complementary thread.

Le piston (8) est également muni à sa périphérie d'un joint torique (27) positionné dans la face intérieure du carter (2), afin d'empêcher que l'huile présente dans la chambre (9, 9') ne se propage respectivement dans l'autre chambre (9', 9) sans passer par les conduits (18) ménagés dans la paroi du carter (2). Le piston (8) est ainsi en contact, à une première extrémité par rapport à la direction A' avec le galet (6) et à l'autre extrémité avec la chambre (9'). Un ressort (16) est positionné dans cette chambre (9'), sensiblement coaxial avec la direction A', entre la face du piston (8) et la face du bouchon proximal (26) adjacente.The piston (8) is also provided at its periphery with an O-ring (27) positioned in the inner face of the housing (2), to prevent the oil in the chamber (9, 9 ') is propagated respectively in the other chamber (9', 9) without going through the ducts (18) formed in the wall of the casing (2). The piston (8) is thus in contact with a first end relative to the direction A 'with the roller (6) and at the other end with the bedroom (9 '). A spring (16) is positioned in this chamber (9 '), substantially coaxial with the direction A ', between the face of the piston (8) and the face of the proximal plug (26) adjacent.

Une soupape de sécurité (17) est également positionnée entre les deux faces opposés du piston (8) par rapport à la direction A', afin de permettre le passage de l'huile de la chambre (9') vers la chambre (9) en cas de surpression. A safety valve (17) is also positioned between the two faces opposing the piston (8) relative to the direction A ', to allow the passage of the oil from the chamber (9 ') to the chamber (9) in case of overpressure.

Un clapet anti-retour (15) est également positionnée entre les deux faces opposés du piston (8) par rapport à la direction D, visible sur la figure 6.A non-return valve (15) is also positioned between the two opposite faces of the piston (8) with respect to the direction D, visible in FIG.

Les deux conduits (18), visibles figures 4 et 5, sont chacun muni d'un pointeau (28) permettant de réguler le flux d'huile et par conséquent la vitesse de retour de la porte dans sa position fermée (0°) et présentent chacun à leur extrémité débouchant sur la face extérieure du carter (2) une bille de blocage (29).The two ducts (18), visible in FIGS. 4 and 5, are each provided with a needle (28) to regulate the oil flow and therefore the speed of return of the door in its closed position (0 °) and each have at their end opening on the face outer casing (2) a locking ball (29).

Un bouchon de remplissage (30) permet de remplir le ferme-porte d'huile à travers la paroi du carter (2).A filler cap (30) is used to fill the door closer with oil through the housing wall (2).

La seconde variante, illustrée figure 7 à 9 diffère de la première essentiellement par le positionnement du clapet anti-retour (15), le nombre de ressorts (16) et l'absence d'un bouchon de remplissage (30), comme on peut le constater en comparant les figures.The second variant, illustrated in FIGS. 7 to 9, differs from the first essentially by the positioning of the non-return valve (15), the number of springs (16) and the absence of a filling plug (30), as can be seen by comparing the figures.

Le ferme-porte (1) permet l'ouverture de la porte dans les deux sens d'ouverture, de 0° à 180° et provoque sa fermeture automatique. Toutefois, il est évident qu'il peut également être utilisé pour une porte ne s'ouvrant que dans un sens et selon un angle moins grand, de 90° par exemple.The door closer (1) allows the opening of the door in both directions of opening, 0 ° to 180 ° and causes its automatic closing. However, it is obvious that he can also be used for a door opening only in one direction and at an angle less large, 90 ° for example.

Ce ferme-porte provoque la fermeture amortie de la porte depuis l'angle maximal d'ouverture jusqu'à la position de fermeture complète.This door closer causes the soft closing of the door from the maximum angle opening to the fully closed position.

Il peut être installé de telle manière qu'il soit complètement invisible pour éviter tout acte de vandalisme. Les moyens de rappel utilisés sont si efficaces qu'il n'est pas nécessaire de prévoir de bras de levier ou de bras coulissant qui dépasse soit de la porte soit du linteau.It can be installed in such a way that it is completely invisible to avoid any act of vandalism. The means of recall used are so effective that it is not necessary to provide lever arm or sliding arm that protrudes either from the door either the lintel.

La force du ferme-porte est réglable de 3 à 5 (au sens de la norme EN1154) par l'intermédiaire d'une vis de réglage sur laquelle il est possible d'agir, par exemple avec une clef six pans.The door closer force is adjustable from 3 to 5 (according to EN1154) by via a set screw on which it is possible to act, for example with a six-sided key.

La vitesse de fermeture est réglable sur deux plages : de 0 à 25° pour la fin de course ; de 0° à 180° sur toute la plage de fermeture.The closing speed is adjustable over two ranges: from 0 to 25 ° for the end of race; from 0 ° to 180 ° over the entire closing range.

Le fonctionnement de la seconde variante du ferme-porte est décrit ci-dessous en référence aux figures 7 à 9 ; toutefois, ce fonctionnement est sensiblement identique à celui de la première variante illustrée figures 1 à 6.The operation of the second variant of the door closer is described below in reference to Figures 7 to 9; however, this operation is substantially identical to that of the first variant illustrated in FIGS. 1 to 6.

Première étape : L'ouverture de la porteStep one: Opening the door

La porte se reprend directement sur l'axe du ferme-porte.The door is taken directly on the axis of the door closer.

L'ouverture de la porte entraíne l'arbre (4) en rotation. Cette rotation provoque la translation de deux pistons (7, 8), par l'intermédiaire des deux galets (5, 6).The opening of the door drives the shaft (4) in rotation. This rotation causes the translation of two pistons (7, 8), via the two rollers (5, 6).

Le piston (7) en se déplaçant vient comprimer les moyens amortisseur constitués de rondelles (10) du type « Belleville » assemblées têtes bêches. L'empilage de rondelles est préalablement précontraint au montage de l'appareil.The piston (7) moving comes to compress the damper means consisting of washers (10) of the "Belleville" type assembled heads spades. The stack of washers is previously prestressed when mounting the device.

Dans le même mouvement de came, le piston hydraulique (8) se déplace, laissant ainsi passer l'huile de la chambre (9) vers la chambre (9') par l'intermédiaire du clapet anti-retour (15).In the same cam movement, the hydraulic piston (8) moves, leaving thus pass the oil from the chamber (9) to the chamber (9 ') via the non-return valve (15).

Deuxième étape : La fermeture de la porteSecond step: closing the door

Lorsque l'opérateur n'agit plus sur la porte après l'avoir ouverte, les moyens de rappel se détendent et exercent sur le piston (7) une force semblable à celle de l'ouverture, mais de sens opposé. Cette force exercée sur le galet (5) induit un couple sur l'arbre (4) par l'intermédiaire du profil de came et ce couple provoque la fermeture de la porte.When the operator no longer acts on the door after opening it, the means of reminder and relax on the piston (7) a force similar to that of the opening, but of opposite sense. This force exerted on the roller (5) induces a torque on the shaft (4) by through the cam profile and this couple causes the closing of the door.

Dans le même temps, par rotation de l'arbre (4), le piston hydraulique (8) est libéré et les ressorts (16) se détendent, entraínant ainsi la translation du piston (8) et la circulation de l'huile de la chambre (9') vers la chambre (9) par l'intermédiaire de deux conduits (18) - suivant les plages de réglages - et de deux pointeaux régulateurs de pression. La fermeture de la porte est ainsi amortie.At the same time, by rotation of the shaft (4), the hydraulic piston (8) is released and the springs (16) relax, thus causing the translation of the piston (8) and the circulation oil from the chamber (9 ') to the chamber (9) via two conduits (18) - following the setting ranges - and two pressure regulator valves. The closure the door is thus damped.

Troisième étape : La fermeture forcéeThird step: Forced closure

Au cours de la fermeture, pour éviter tous dommages à l'appareil lors d'une fermeture forcée (action par exemple d'un opérateur agissant sur la porte violemment dans le sens de la fermeture), l'huile ne passe plus de la chambre (9') vers la chambre (9) par les conduits (18) mais directement à travers la soupape de sécurité (17) positionnée dans le piston (8).During the closing, to avoid any damage to the device during a forced closure (eg action of an operator acting on the door violently in the direction of closing), the oil no longer passes from the chamber (9 ') to the chamber (9) by the ducts (18) but directly through the safety valve (17) positioned in the piston (8).

La pression de déclenchement de la soupape s'obtient de conception : pas de tarage nécessaire, la raideur du ressort de la soupape, sa longueur en charge et la surface de passage de l'huile définissent cette pression.The triggering pressure of the valve is obtained from design: no calibration necessary, the stiffness of the spring of the valve, its length in charge and the surface of Oil passage define this pressure.

Grâce au procédé de fabrication selon l'invention, on simplifie le choix des moyens de fermeture en fonction du couple souhaité. En effet, connaissant les valeurs de résistance à la compression de chaque rondelle, il est possible de réaliser les moyens de rappel en sélectionnant une pluralité de rondelles Belleville (10) identiques ou différentes et en montant sensiblement coaxialement lesdites rondelles Belleville (10) selon ladite deuxième direction A', ladite sélection et ledit montage étant opérés en fonction de la force souhaitée qui est exercée par lesdits moyens de rappel sur ledit premier piston (7), en intégrant, par exemple le poids de la porte ou un poids moyen.Thanks to the manufacturing method according to the invention, the choice of means is simplified. closing according to the desired torque. Indeed, knowing the resistance values at the compression of each washer, it is possible to realize the return means in selecting a plurality of identical or different Belleville washers (10) and substantially coaxially mounting said Belleville washers (10) according to said second direction A ', said selection and said assembly being operated according to the desired force which is exerted by said biasing means on said first piston (7), integrating, by example the weight of the door or an average weight.

Il peut en outre être nécessaire de définir un profil de came particulier pour l'arbre d'entraínement (4), pour coordonner la faible course avec l'effort important transmis. La définition de cette forme est à la portée de l'homme du métier.It may further be necessary to define a particular cam profile for the tree of training (4), to coordinate the weak race with the important effort transmitted. The definition of this form is within the reach of the skilled person.

La présente invention est décrite dans ce qui précède à titre d'exemple. Il est entendu que l'homme du métier est à même de réaliser différentes variantes de l'invention sans pour autant sortir du cadre du brevet tel que défini par les revendications.The present invention is described in the foregoing by way of example.
