Description

L'invention se rapporte à un dispositif de verrouillage de porte à crémone, plus particulièrement du genre destiné à être installé dans un montant tubulaire fixé le long de ladite porte et s'étendant jusqu'à un bord de celle-ci pour que ladite crémone puisse coopérer avec une gâche ancrée au mur ou à l'huisserie. L'invention s'applique particulièrement à la fermeture d'une porte en verre munie d'un tel montant abritant ledit dispositif de verrouillage, ce montant étant installé verticalement et maintenu à distance du plan de la porte par des entretoises.The invention relates to a cremone door locking device, more particularly of the type intended to be installed in a tubular upright fixed along said door and extending to an edge thereof for said cremone can cooperate with a strike anchored to the wall or the frame. The invention is particularly applicable to the closure of a glass door provided with such an amount housing said locking device, this amount being installed vertically and kept away from the plane of the door by spacers.

Le dispositif selon l'invention peut être actionné par un barillet, voir deux, ou bien par un barillet et un bouton rotatif.The device according to the invention can be actuated by a barrel, see two, or by a barrel and a rotary knob.

Dans un dispositif du genre défini ci-dessus, l'action d'une clé dans un barillet ou l'action d'un bouton de porte génère un mouvement de rotation qui doit être converti en translation des tiges de crémone. La plupart des systèmes actuels utilise des cylindres à profil dit "européen". Dans ce cas, un paneton est actionné en rotation par le barillet du cylindre. Généralement, ce mouvement de rotation est libre sur 270° puis, sur 45° le paneton pousse un premier piston déverrouillant la fourchette d'entraînement des crémones. Enfin, sur les 45° restant, il entraîne la fourchette solidaire des crémones. L'entraînement effectif des crémones est donc réalisé sur seulement un huitième de tour de clé, ce qui produit la sensation désagréable d'un mouvement saccadé et brutal, avec des à-coups successifs. De plus, cette faible course utile impose de faire au moins deux tours de clés pour engager les pênes de la crémone dans les gâches sur une profondeur suffisante d'au moins 25 à 30 mm.In a device of the kind defined above, the action of a key in a cylinder or the action of a door knob generates a rotational movement which must be converted into translation of the espagnolette rods. Most current systems use so-called "European" profile cylinders. In this case, a peg is rotated by the barrel of the cylinder. Generally, this rotational movement is free on 270 ° and then, over 45 ° the paneton pushes a first piston unlocking the drive fork of the cremones. Finally, on the 45 ° remaining, it drives the fork of the cremones. The effective training of the cremones is thus realized on only one eighth of turn of key, which produces the unpleasant sensation of a jerky and brutal movement, with successive jolts. In addition, this small useful stroke requires at least two turns of keys to engage the bolts of the espagnolette in strikes to a sufficient depth of at least 25 to 30 mm.

Surtout, pour un tel cylindre à profil européen, l'enveloppe extérieure du paneton dans son mouvement de rotation est très large, de sorte que le cylindre ne peut être logé que dans un tube de diamètre intérieur supérieur à 32 mm.Especially, for such a cylinder European profile, the outer casing of the blade in its rotational movement is very wide, so that the cylinder can be housed only in a tube of internal diameter greater than 32 mm.

Enfin, ce système procède toujours d'un empilage de pièces assez fragiles que des sollicitations anormales peuvent détériorer rapidement.Finally, this system always proceeds from a stack of fairly fragile parts that abnormal stresses can deteriorate quickly.

L'invention permet de surmonter tous ces inconvénients.The invention overcomes all these disadvantages.

L'un des buts de l'invention est de proposer un dispositif de verrouillage peu encombrant et susceptible d'être actionné sur toute la course d'un barillet ou d'un bouton rotatif.One of the aims of the invention is to provide a locking device that is compact and can be actuated over the entire stroke of a barrel or a rotary knob.

Plus particulièrement, l'invention concerne un dispositif de verrouillage de porte à crémone comprenant au moins une tige de crémone faisant saillie à une extrémité d'un boîtier allongé, caractérisé en ce que ladite tige de crémone est raccordée à un premier support de crémaillère, monté coulissant à l'intérieur du boîtier, en ce que ledit boîtier abrite un second support de crémaillère monté coulissant à l'intérieur dudit boîtier et installé en regard du premier, en ce que chaque support de crémaillère porte un tronçon de crémaillère muni d'une denture en prise avec un pignon installé entre les deux tronçons de crémaillère, en ce qu'au moins un tronçon de crémaillère est articulé à son propre support de crémaillère et en ce que la denture de ce tronçon de crémaillère articulé se prolonge sur une portion courbe d'une extrémité libre de ce tronçon de façon à permettre le pivotement en fin de course et l'arc-boutement dudit tronçon de crémaillère articulé, assurant l'irréversibilité du déplacement de ladite tige de crémone.More particularly, the invention relates to a cremone door locking device comprising at least one espagnolette rod projecting from one end of an elongate housing, characterized in that said cremone rod is connected to a first rack support, slidably mounted within the housing, in that said housing houses a second rack support slidably mounted inside said housing and installed opposite the first, in that each rack support carries a rack section provided with a toothing engaged with a pinion installed between the two rack sections, in that at least one rack section is articulated to its own rack support and in that the toothing of this articulated rack section extends over a portion curve of a free end of this section so as to allow pivoting at the end of stroke and the bracing of said section of articulated rack, ensuring the irreversibility of the movement of said cremone rod.

Ainsi, l'actionnement réparti sur toute la course du barillet et non plus sur le 8ème de celle-ci, ne nécessite qu'un tour de clé.Thus, actuation distributed over the entire stroke of the cylinder and not on the 8th thereof, requires only a turn of the key.

De plus, l'effort que l'on doit exercer sur la clé pendant cet unique tour de clé est relativement constant.In addition, the effort that must be exerted on the key during this single turn key is relatively constant.

De préférence, chaque support de crémaillère porte un tronçon de crémaillère articulé dont la denture se prolonge sur une portion courbe de son extrémité libre, les axes de pivotement des deux tronçons étant parallèles à l'axe dudit pignon et en symétrie par rapport à celui-ci.Preferably, each rack support carries a hinged rack section whose teeth are extended on a curved portion of its free end, the pivot axes of the two sections being parallel to the axis of said pinion and in symmetry with respect to this. this.

Avantageusement, ledit pignon est un pignon d'actionnement relié à des moyens de commande rotatifs, comme par exemple un barillet de serrure ou un simple bouton.Advantageously, said pinion is an actuating gear connected to rotary control means, such as for example a lock cylinder or a simple button.

Ces moyens de commande peuvent comporter un barillet de sécurité cylindrique mais à entraînement axial, ce qui permet de réduire le diamètre du tube formant le boîtier de ce cylindre. Ce tube constitue le plus souvent une entretoise d'un montant cylindrique fixé à la porte et formant une poignée de celle-ci.These control means may comprise a cylindrical safety cylinder but axial drive, which reduces the diameter of the tube forming the housing of the cylinder. This tube is most often a spacer of a cylindrical amount attached to the door and forming a handle thereof.

La commande peut être effectuée par une tige de relativement faible diamètre. Le perçage de la porte est donc d'un diamètre beaucoup plus faible qu'avec un barillet à paneton du type à profil européen.The control can be performed by a rod of relatively small diameter. The drilling of the door is therefore much smaller in diameter than with a paneton cylinder of the European profile type.

De préférence, ledit second support de crémaillère est raccordé à une seconde tige de crémone faisant saillie à l'extrémité opposée dudit boîtier allongé. On peut donc facilement réaliser un double verrouillage, haut et bas.Preferably, said second rack support is connected to a second espagnolette rod projecting from the opposite end of said elongated housing. We can easily achieve a double lock, up and down.

Le boîtier peut être globalement cylindrique et de faible diamètre, ce qui permet de l'intégrer facilement à un montant tubulaire fixe, installé le long de la porte, le plus souvent verticalement.The housing can be generally cylindrical and small diameter, which allows to easily integrate a fixed tubular upright, installed along the door, usually vertically.

Selon un mode de réalisation avantageux, le dispositif est caractérisé en ce que chaque support de crémaillère porte un autre tronçon de crémaillère muni d'une denture en prise avec un pignon à rotation libre et d'axe fixe par rapport au boîtier, monté entre lesdits autres tronçons de crémaillère et engrenant avec eux.According to an advantageous embodiment, the device is characterized in that each rack support carries another rack section provided with a toothing in engagement with a pinion with free rotation and fixed axis relative to the housing, mounted between said other sections of rack and meshing with them.

Ainsi, ce deuxième pignon dont la rotation est libre mais dont l'axe est supporté par des paliers, idéalement des roulements à billes sert à immobiliser l'ensemble dans l'espace et: à équilibrer les masses des crémones et des pênes haut et bas. Le premier pignon cité est utilisé pour l'entraînement de l'ensemble et ne supporte plus aucun effort vertical. Il n'est pas bloqué verticalement mais simplement soutenu sans contrainte par les crémaillères qu'il actionne.Thus, this second gear whose rotation is free but whose axis is supported by bearings, ideally ball bearings is used to immobilize the assembly in space and: to balance the masses of cremone bolts and bolts up and down . The first pinion cited is used to drive the whole and no longer supports any vertical force. It is not blocked vertically but simply supported without constraint by the racks it operates.

Cependant, on peut imaginer de ne pas avoir recours à ce deuxième pignon et à ces autres tronçons de crémaillère en prévoyant des paliers supports ou roulements entre le pignon d'actionnement et le boîtier, si on dispose d'une place suffisante dans le boîtier.However, it is conceivable not to use this second pinion and these other rack sections by providing support bearings or bearings between the drive pinion and the housing, if there is sufficient space in the housing.

L'invention sera mieux comprise et d'autres avantages de celle-ci apparaîtront plus clairement à la lumière de la description qui va suivre d'un mode de réalisation actuellement préféré d'un dispositif de verrouillage de porte à crémone conforme à son principe, donnée uniquement à titre d'exemple et faite en référence aux dessins annexés dans lesquels :

The invention will be better understood and other advantages thereof will appear more clearly in the light of the following description of a presently preferred embodiment of a cremone door locking device according to its principle, given only by way of example and with reference to the appended drawings in which:
  • the Figures 1 to 3 are cross-sectional views of a cremone door locking device according to the invention, shown in different states, to illustrate its operation;

Sur les dessins, on a représenté un dispositif de verrouillage 11 de porte, à crémone, aménagé à l'intérieur d'un boîtier 13 allongé, ici globalement cylindrique. Le boîtier pourrait aussi être parallélépipédique. Le dispositif comporte au moins une tige de crémone faisant saillie à une extrémité du boîtier 13. Dans l'exemple et de façon avantageuse, le dispositif comporte deux tiges de crémone 15, 17, faisant respectivement saillie aux deux extrémités 19, 21 opposées du boîtier cylindrique 13. Chaque tige 15, 17 forme un pêne à son extrémité libre et ce pêne coopère avec une gâche 23, 24 ancrée au mur ou à l'huisserie, ici près des bords supérieur et inférieur de la porte.In the drawings, there is shown a locking device 11 door, cremone, arranged inside an elongate housing 13, here generally cylindrical. The case could also be parallelepipedic. The device comprises at least one espagnolette rod projecting from one end of the casing 13. In the example and advantageously, the device comprises two espagnolette rods 15, 17 projecting respectively at the two opposite ends 19, 21 of the casing cylindrical 13. Each rod 15, 17 forms a bolt at its free end and the bolt cooperates with a striker 23, 24 anchored to the wall or the frame, here near the upper and lower edges of the door.

La tige de crémone 15, faisant saillie à l'extrémité 19 du boîtier, est raccordée à un premier support de crémaillère 25 monté coulissant à l'intérieur du boîtier 13.The cremone rod 15 protruding from the end 19 of the housing is connected to a first rack support 25 slidably mounted inside the housing 13.

Ce boîtier abrite un second support de crémaillère 27. Ce dernier est monté coulissant dans le boîtier et installé en regard du premier.This housing houses a second rack support 27. The latter is slidably mounted in the housing and installed opposite the first.

Les deux supports de crémaillère coulissent sans se rencontrer, en sens inverse l'un de l'autre.The two rack supports slide without meeting, in opposite directions from each other.

Dans l'exemple, le second support de crémaillère 27 est raccordé à la seconde tige de crémone 17 qui fait saillie à l'extrémité 21 du boîtier.In the example, the second rack support 27 is connected to the second espagnolette rod 17 which protrudes at the end 21 of the housing.

Chaque support de crémaillère 25, 27 porte un tronçon de crémaillère 31, 33 articulé à ce support et muni d'une denture 31a, 33a en prise avec un pignon 35 installé entre les deux tronçons de crémaillère. Les axes 31b, 33b des deux tronçons de crémaillère sont parallèles à l'axe immatériel 36 du pignon 35 et en symétrie par rapport à celui-ci.Each rack support 25, 27 carries a rack section 31, 33 articulated to this support and provided with a toothing 31a, 33a in engagement with a pinion 35 installed between the two rack sections. The axes 31b, 33b of the two rack sections are parallel to the intangible axis 36 of the pinion 35 and in symmetry with respect thereto.

La denture d'au moins un tronçon de crémaillère, avantageusement, la denture de chaque tronçon de crémaillère se prolonge sur une portion courbe 31c, 33c d'une extrémité libre dudit tronçon 31, 33, de façon à permettre le pivotement en fin de course et l'arc-boutement des deux tronçons de crémaillère de part et d'autre dudit pignon. Autrement dit, l'extrémité libre du ou chaque tronçon de crémaillère est pourvue de dents d'engrenage. C'est ce mouvement de fin de course, visible particulièrement sur la figure 3, qui assure l'irréversibilité du déplacement de la ou chaque tige de crémone 15, 17.The toothing of at least one rack section, advantageously, the toothing of each rack section is extended on a curved portion 31c, 33c of a free end of said section 31, 33, so as to allow pivoting at the end of the race and the bracing of the two rack sections on either side of said pinion. In other words, the free end of the or each rack section is provided with gear teeth. It is this end movement race, visible particularly on the figure 3 which ensures the irreversibility of the displacement of the or each cremone rod 15, 17.

Dans l'exemple décrit, le pignon 35 est un pignon d'actionnement relié à des moyens de commande rotatifs. Par moyens de commande rotatifs, on entend tout élément ou sous-ensemble mécanique susceptible d'être couplé à l'axe du pignon pour en commander l'entraînement en rotation. Il peut comprendre d'un simple bouton d'actionnement (figure 6) prolongé par une tige venant s'accoupler axialement au pignon ou bien un barillet de sécurité cylindrique à entraînement axial (figure 7), actionné par une clé, lui-même prolongé par une tige. Le dispositif tel que décrit sur les figures 1 à 3 prend avantageusement place à l'intérieur d'un tube 39 formant poignée monté par l'intermédiaire d'entretoises le long d'une porte, et s'étendant typiquement du haut en bas de la porte. Un trou, pratiqué dans le boîtier 13 en regard de l'axe du pignon 35 permet le passage d'une tige faisant partie desdits moyens de commande rotatif. Avantageusement, le boîtier comporte deux trous alignés, de part et d'autre du pignon d'actionnement de façon à permettre le couplage d'un élément d'actionnement intérieur et d'un élément d'actionnement extérieur.In the example described, the pinion 35 is an actuating gear connected to rotary control means. Rotary control means means any mechanical element or subassembly capable of being coupled to the axis of the pinion to drive the rotation drive. It can include a simple actuation button ( figure 6 ) extended by a pin coming axially to the pinion or a cylindrical safety cylinder with axial drive ( figure 7 ), operated by a key, itself extended by a rod. The device as described on the Figures 1 to 3 advantageously takes place inside a tube 39 forming a handle mounted via spacers along a door, and typically extending from the top to the bottom of the door. A hole made in the housing 13 facing the axis of the pinion 35 allows the passage of a rod forming part of said rotary control means. Advantageously, the housing comprises two aligned holes, on either side of the actuating pinion so as to allow the coupling of an inner actuating element and an external actuating element.

Le tube 39 contenant le dispositif de verrouillage est de préférence placé du côté intérieur. Les moyens de commande rotatifs (figure 7) peuvent être engagés dans une entretoise reliant le tube à la porte.The tube 39 containing the locking device is preferably placed on the inside. The rotary control means ( figure 7 ) can be engaged in a spacer connecting the tube to the door.

Comme on le voit sur la figure 4, chaque tronçon de crémaillère 31, 33 comporte un ergot 31d, 33d coulissant dans une rainure 31e, 33e correspondante. Cette rainure est creusée dans la paroi intérieure du boîtier 13. La forme de la rainure recopie la trajectoire de l'ergot lorsque le tronçon de crémaillère se déplace et pivote en fin de course. Ainsi, en position de verrouillage, la mise en butée de l'ergot contre le flanc d'une portion d'extrémité courbe 31f, 33f de la rainure correspondante, qui s'étend transversalement au trajet du support de crémaillère permet d'éviter que des efforts s'exerçant sur les tiges 15, 17, axialement dans un sens tendant à les faire rentrer dans le boîtier, ne s'exercent sur le pignon, au risque de provoquer des contraintes excessives dans les dentures du pignon et des crémaillères, voire une ovalisation du pignon. En d'autres termes, l'irréversibilité du mécanisme est essentiellement assurée par cette mise en butée des ergots 31d, 33d contre les flancs des portions d'extrémité courbes des rainures 31e, 33e correspondantes.As we see on the figure 4 , each rack section 31, 33 comprises a pin 31d, 33d sliding in a groove 31e, 33e corresponding. This groove is hollowed in the inner wall of the housing 13. The shape of the groove copying the trajectory of the lug when the rack portion moves and pivots at the end of the stroke. Thus, in the locking position, the abutment of the lug against the side of a curved end portion 31f, 33f of the corresponding groove, which extends transversely to the path of the rack support prevents that forces acting on the rods 15, 17, axially in a direction tending to get them into the housing, are exerted on the pinion, the risk of causing excessive stresses in the teeth of the pinion and racks, or ovalization of the pinion. In other words, the irreversibility of the mechanism is essentially ensured by this abutting of the lugs 31d, 33d against the flanks of the curved end portions of the corresponding grooves 31e, 33e.

Par ailleurs, chaque support de crémaillère 25, 27 porte un autre tronçon de crémaillère 45, 47 non articulé, muni d'une denture en prise avec un pignon à rotation libre 49 et d'axe fixe par rapport au boîtier. Ce pignon est monté entre les deux autres tronçons de crémaillère 45, 47 et engrène avec eux. Le pignon à rotation libre 49 est supporté par des paliers solidaires du boîtier. Avantageusement, ces paliers sont constitués par des roulements à billes 51 ou analogues.Furthermore, each rack support 25, 27 carries another rack portion 45, 47 not articulated, provided with a toothing engaged with a freely rotating pinion 49 and fixed axis relative to the housing. This pinion is mounted between the two other rack sections 45, 47 and meshes with them. The freely rotating pinion 49 is supported by bearings integral with the housing. Advantageously, these bearings are constituted by ball bearings 51 or the like.

Comme représenté sur la figure 5, la partie centrale du pignon d'actionnement 35 est évidée pour recevoir l'extrémité d'une tige d'actionnement. Cet évidement a la forme d'une cavité d'accouplement multilobulaire 53. Cette forme, présentant des lobes 54 faisant saillie circonférentiellement à l'intérieur de la cavité 53, est connue pour permettre la transmission d'un couple élevé. La cavité est donc adaptée à recevoir l'extrémité d'une tige d'actionnement 55 de forme complémentaire, solidaire ou couplée à un organe de manoeuvre. Par exemple, la figure 6 montre un bouton 57 de manoeuvre (pouvant notamment être utilisé pour manoeuvrer le dispositif de l'intérieur d'un local). Ce bouton 57 se prolonge par la tige 55 dont l'extrémité a une forme complémentaire de celle de la cavité pour pouvoir s'y engager axialement.As shown on the figure 5 , the central portion of the actuating pinion 35 is recessed to receive the end of an actuating rod. This recess is in the form of a multilobular coupling cavity 53. This shape, having lobes 54 protruding circumferentially inside the cavity 53, is known to allow the transmission of a high torque. The cavity is therefore adapted to receive the end of an actuating rod 55 of complementary shape, integral or coupled to an operating member. For example, the figure 6 shows a button 57 maneuver (which can be used to manipulate the device from the inside of a room). This button 57 is extended by the rod 55 whose end has a shape complementary to that of the cavity to engage axially.

L'un des lobes 54 de la cavité est supprimé pour l'indexage du système. De cette façon, le dispositif peut être actionné par un barillet de sécurité 41, ici cylindrique, à clé, le mouvement du barillet et celui du dispositif de verrouillage à crémone étant cinématiquement "synchronisés" par ce type d'indexage simple.One of the lobes 54 of the cavity is removed for indexing the system. In this way, the device can be actuated by a safety cylinder 41, here cylindrical, key, the movement of the barrel and that of the espagnolette locking device being kinematically "synchronized" by this type of simple indexing.

Le barillet peut avoir une autre forme. L'invention est compatible avec un cylindre à profil dit "européen".The barrel may have another shape. The invention is compatible with a so-called "European" profile cylinder.

La figure 7 illustre schématiquement le montage du barillet 41 dans un tube 61 monté perpendiculairement à la porte 62 dans l'axe du pignon d'actionnement 35. Le paneton de ce type de barillet, à l'extrémité de celui-ci, tourne dans le boîtier du barillet et comporte une empreinte dans laquelle s'engage un socle 42 (de forme complémentaire) prolongé par une tige 55a semblable à celle du bouton 57 de la figure 6 et dont l'extrémité s'engage dans la cavité 53 du pignon d'actionnement. Le diamètre de cette tige étant faible, celui du trou 65 pratiqué dans la porte 62, l'est aussi.The figure 7 schematically illustrates the mounting of the barrel 41 in a tube 61 mounted perpendicularly to the door 62 in the axis of the drive pinion 35. The bit of this type of barrel, at the end thereof, rotates in the housing of the barrel and has an impression in which engages a base 42 (of complementary shape) extended by a rod 55a similar to that of the button 57 of the figure 6 and whose end engages in the cavity 53 of the actuating pinion. The diameter of this rod being low, that of the hole 65 made in the door 62, is also.

Le fonctionnement découle avec évidence de la description qui précède. Dans la situation de la figure 1, la porte est en situation de fermeture mais n'est pas verrouillée. Les deux tiges de crémone 15, 17 sont en regard des gâches 23, 24 mais ne s'y engagent pas.The operation is evident from the foregoing description. In the situation of figure 1 , the door is closed but not locked. The two cremone rods 15, 17 are opposite strikes 23, 24 but do not engage.

Dans la situation de la figure 2, les moyens de commande rotatif ont été manoeuvrés pour provoquer les déplacements en sens inverse des deux supports de crémone 25, 27, par engrènement entre le pignon 35 et les deux tronçons de crémaillère 31, 33 articulés. Cette première partie de l'actionnement du dispositif se traduit par un engagement des tiges dans les gâches respectives sans pivotement des tronçons de crémaillère 31, 33. Le verrouillage est effectif mais est encore réversible car, si on exerce un effort axial rentrant sur l'une ou l'autre tige 15, 17, on provoque la rétractation desdites tiges et par conséquent la réouverture de la porte.In the situation of figure 2 , the rotary control means have been operated to cause displacements in opposite directions of the two cremone supports 25, 27, by meshing between the pinion 35 and the two articulated rack sections 31, 33. This first part of the actuation of the device results in an engagement of the rods in the respective latches without pivoting the rack sections 31, 33. The locking is effective but is still reversible because, if it exerts an axial force returning to the one or the other rod 15, 17, it causes the retraction of said rods and therefore the reopening of the door.

Cependant, comme le montre la figure 3, la fin de course d'actionnement du dispositif de verrouillage provoque (du fait que la denture de chaque tronçon de crémaillère 31, 33 se prolonge sur une portion courbe d'une extrémité libre de ce tronçon) le pivotement et l'arc-boutement des deux tronçons de crémaillère de part et d'autre du pignon 35. Comme mentionné précédemment, dans cette situation, les efforts axiaux pouvant s'exercer sur les tiges sont en fait repris par la mise en butée des ergots 31d, 33d contre les flancs des portions d'extrémité courbes des rainures 31e, 33e correspondantes. Le pignon 35 évidé est donc soustrait à toute sollicitation tendant à l'écraser entre les extrémités des deux tronçons de crémaillère.However, as shown in figure 3 , the actuation end of the locking device causes (because the toothing of each rack section 31, 33 is extended on a curved portion of a free end of this section) the pivoting and the bracing of the two rack sections on either side of the pinion 35. As mentioned above, in this situation, the axial forces that can exert on the rods are in fact resumed by the abutment of the lugs 31d, 33d against the flanks curved end portions of the corresponding grooves 31e, 33e. The hollow pinion 35 is therefore exempt from any stress tending to crush it between the ends of the two rack sections.
