Description

L'invention concerne une crémone ou crémone-serrure pour porte, porte-fenêtre ou analogue, comprenant, logé dans un boítier central un mécanisme de commande conçu apte à actionner au moins une tringle de manoeuvre et comportant, d'une part, des moyens élastiques pour le rappel automatique en position de verrouillage de la tringle de manoeuvre ainsi que des moyens de commande manuels, plus particulièrement un fouillot actionné par une poignée de commande, pour assurer notamment le déverrouillage de cette tringle de manoeuvre et le réarmement des moyens élastiques et, d'autre part, un dispositif de blocage apte à maintenir dans sa position déverrouillée la tringle de manoeuvre après ouverture de l'ouvrant de la porte, porte-fenêtre ou analogue, et des moyens de déblocage à même de désactiver ledit dispositif de blocage au moment de refermer l'ouvrant sur le cadre dormant pour permettre le rappel en position de verrouillage de ladite tringle de manoeuvre.The invention relates to a cremone bolt or door bolt, French window or the like, comprising, housed in a housing central control mechanism designed capable of operating at less an operating rod and comprising, on the one hand, elastic means for automatic return to position locking of the operating rod as well as means of manual control, more specifically an actuated follower by a control handle, to ensure in particular the unlocking of this operating rod and rearming elastic means and, on the other hand, a device for blocking able to maintain in its unlocked position the operating rod after opening the door leaf, French window or the like, and unlocking means capable of deactivate said blocking device when closing opening it on the frame to allow the recall in locking position of said operating rod.

La présente invention trouvera son application dans le domaine de la quincaillerie du bâtiment et concerne, plus particulièrement, les ferrures de verrouillage.The present invention will find its application in the field of the building hardware and concerns, more particularly the locking fittings.

En fait, l'on observera qu'il est d'ores et déjà connu des crémones ou crémones-serrures répondant à la description ci-dessus. De telles crémones ont pour but de faciliter la manoeuvre de verrouillage de la porte, porte-fenêtre ou analogue dans la mesure où la ou les tringles de manoeuvre sont automatiquement repoussées dans leur position de verrouillage sur l'influence de moyens de rappels élastiques dont l'action est, précisément, libérée au moment même où l'ouvrant est refermé sur le cadre dormant. Contrairement, lors du déverrouillage et de l'ouverture de cet ouvrant, la manoeuvre exécutée par l'usager sur une poignée de commande a pour conséquence de ramener cette ou ces tringles de manoeuvre dans leur position déverrouillée et d'assurer le réarmement des moyens élastiques précités, tandis qu'un dispositif de blocage approprié vient, simultanément, maintenir dans cette position déverrouillée la ou les tringles de manoeuvre contre l'action du ressort constituant, substantiellement, lesdits moyens de rappel élastiques.In fact, it will be observed that it is already known to cremone bolts or lock bolts corresponding to the above description. The purpose of such cremone bolts is to facilitate door, patio door or analogous insofar as the operating rod or rods are automatically pushed back into their locked position on the influence of elastic recall means whose action is, precisely, released at the very moment when the opening is closed on the sleeping frame. In contrast, during unlocking and opening this opening, the operation executed by the user on a control handle has for consequence of bringing this or these operating rods into their unlocked position and ensuring the rearmament of said elastic means, while a blocking device appropriate comes, simultaneously, maintain in this position unlocked the operating rod (s) against the action of the jurisdiction constituting, substantially, said means of elastic recall.

En fin de compte, une telle crémone comporte, encore, des moyens de déblocage qui sont à même de désactiver le dispositif de blocage au moment de refermer l'ouvrant sur le cadre dormant pour permettre le rappel en position de verrouillage de cette ou ces tringles de manoeuvre.Ultimately, such a cremone bolt, again, unlocking means which are able to deactivate the device blocking when closing the sash on the frame to allow the recall in the locked position of this or these operating rods.

Une crémone répondant à cette description a tout particulièrement été décrite dans le document FR-2.500.874. Dans ce cas d'espèce, le dispositif de blocage consiste en un doigt de blocage monté basculant au niveau d'une têtière abritant, usuellement, les différents organes de la crémone ou crémone-serrure à hauteur du chant avant de l'ouvrant. En fait, ce doigt de blocage agit dans le sens du mouvement de cet ouvrant de sorte qu'au moment d'ouvrir celui-ci il vient basculer automatiquement, dans la direction du cadre dormant, ceci sous l'impulsion d'un ressort tandis, qu'au moment de refermer cet ouvrant, le cadre dormant est à même de repousser ce doigt de blocage contre ledit ressort.A cremone bolt meeting this description has it all particularly described in document FR-2,500,874. In this case, the blocking device consists of a locking finger mounted tilting at the level of a headrest usually hosting the various organs of the cremone bolt or cremone bolt at the height of the edge before the opening. In fact, this locking finger acts in the direction of movement of this opening so that when it opens it comes switch automatically, in the direction of the frame, this under the impulse of a spring while, at the time of close this opening, the sleeping frame is able to push back this locking finger against said spring.

Il convient d'observer qu'un tel doigt de blocage est prolongé, au niveau de sa partie interne au boítier renfermant le mécanisme de commande par un levier par l'intermédiaire duquel il est, précisément, à même de maintenir la ou les tringles de manoeuvre dans leur position déverrouillée, ceci au moment même d'ouvrir l'ouvrant et, donc, dès que ce doigt de blocage a pu être libéré du cadre dormant. It should be noted that such a locking finger is extended, at the level of its internal part to the case containing the lever control mechanism through which it is, precisely, able to maintain the rod (s) of maneuver in their unlocked position, at the same time to open the sash and, as soon as this locking finger has been able be released from the sleeping frame.

En fait, une telle solution présente l'inconvénient que le mécanisme déclencheur est dissocié d'un organe de verrouillage de la crémone ou crémone-serrure. Il en résulte des effets non synchrones entre le déclencheur et, plus particulièrement, le pêne demi-tour qui est le premier de ces organes de verrouillage à entrer en contact avec une gâche du cadre dormant. Aussi, l'un ou l'autre de ces éléments peut venir percuter un organe de ce cadre dormant, par exemple, une gâche.In fact, such a solution has the disadvantage that the trigger mechanism is dissociated from a locking member of the cremone bolt or bolt lock. This results in effects not synchronous between the trigger and, more particularly, the bolt which is the first of these organs of lock to come into contact with a frame keeper sleeping. So either of these can come strike a member of this sleeping frame, for example, a strike.

De plus, un tel doigt de blocage doit, à lui seul et par l'intermédiaire de son levier de blocage disposé intérieurement au boítier, s'opposer à l'action des moyens de rappel élastiques destinés à rappeler la ou les tringles de manoeuvre en position de verrouillage.In addition, such a locking finger must, by itself and by through its internally arranged locking lever to the housing, to oppose the action of the recall means elastic bands to recall the operating rod (s) in the locked position.

En fait, la démarche inventive de la présente invention a consisté à séparer la fonction de retenue en position déverrouillée de la ou des tringles de manoeuvre de celle consistant à désactiver cette fonction de retenue au moment de refermer l'ouvrant sur le cadre dormant.In fact, the inventive step of the present invention has consisted in separating the restraint function in position unlocked from the operating rod (s) of that consisting of deactivating this restraint function when close the door on the frame.

A cet effet, l'invention concerne une crémone ou crémone-serrure pour porte, porte-fenêtre ou analogue comprenant, logé dans un boítier central, un mécanisme de commande conçu apte à actionner au moins une tringle de manoeuvre et comportant, d'une part, des moyens élastiques pour le rappel automatique en position de verrouillage de la tringle de manoeuvre, ainsi que des moyens de commande manuels, plus particulièrement un fouillot actionné par une poignée de commande, pour assurer notamment le déverrouillage de cette tringle de manoeuvre et le réarmement des moyens élastiques et, d'autre part, un dispositif de blocage apte à maintenir, dans sa position déverrouillée, la tringle de manoeuvre après ouverture de l'ouvrant et des moyens de déblocage à même de désactiver le dispositif de blocage au moment de refermer l'ouvrant sur le cadre dormant pour permettre le rappel en position de verrouillage de ladite tringle de manoeuvre, caractérisé par le fait que ledit dispositif de blocage consiste en une genouillère composée d'au moins deux biellettes reliées à l'aide d'un pivot, l'une de ces biellettes étant en outre rendue solidaire, par une articulation, de la tringle ou d'un chevalet relié à cette dernière, tandis que l'autre biellette est rendue solidaire par une articulation dudit boítier, ceci de telle sorte que, en position de déverrouillage, de la tringle de manoeuvre, le pivot et les deux articulations de cette genouillère viennent se situer, sensiblement, dans un même alignement parallèle au déplacement de ladite tringle ou du chevalet pour venir étayer cette ou ce dernier dans une position d'équilibre instable.To this end, the invention relates to a cremone bolt or bolt lock for door, French window or the like comprising, housed in a central box, a control mechanism designed capable of actuate at least one operating rod and comprising, on the one hand, elastic means for the automatic recall in locking position of the operating rod, as well as manual control means, more particularly a follower operated by a control handle, to ensure in particular the unlocking of this operating rod and the resetting of the elastic means and, on the other hand, a blocking device able to maintain, in its position unlocked, the operating rod after opening the opening and unlocking means able to deactivate the blocking device when closing the door on the frame to allow the return to the position of locking of said operating rod, characterized by that said blocking device consists of a knee brace made up of at least two links connected to using a pivot, one of these links being further made integral by a joint, the rod or a bridge connected to the latter, while the other link is made integral by an articulation of said housing, this so that, in the unlocked position, the operating rod, the pivot and the two joints of this kneepad is located, substantially, in a same alignment parallel to the displacement of said rod or the easel to support this or the latter in a unstable equilibrium position.

Quant aux moyens de déblocage, ceux-ci consistent, substantiellement, en un doigt de commande apte à repousser la genouillère lorsque celle-ci est dans sa position d'équilibre instable pour autoriser le verrouillage de la tringle de manoeuvre sous l'action des moyens élastiques, ce doigt de commande étant associé à un pêne demi-tour soumis à un ressort de rappel en position de verrouillage et comportant un organe de retenue apte à maintenir ce pêne demi-tour dans une position déverrouillée ou semi-déverrouillée, cet organe de retenue étant conçu apte à coopérer, directement ou indirectement avec ce cadre dormant au moment de refermer l'ouvrant pour libérer ledit pêne demi-tour et, sous l'impulsion du doigt de commande associé à ce dernier, assurer le verrouillage de la tringle de manoeuvre.As for the unlocking means, these consist, substantially, in a control finger capable of repelling the knee brace when it is in its equilibrium position unstable to allow locking of the rod maneuver under the action of elastic means, this finger control being associated with a latch bolt subjected to a spring in the locking position and comprising a member retainer capable of holding this latch bolt in a position unlocked or semi-unlocked, this retaining member being designed to cooperate, directly or indirectly with this frame sleeping when closing the door to release said latch turn and, under the impulse of the control finger associated with the latter, ensure the locking of the rod maneuver.

Les avantages découlant de la présente invention consistent en ce que la ou les tringles de manoeuvre sont maintenues dans leur position déverrouillée, contre l'action des moyens élastiques destinés à assurer leur rappel en position de verrouillage, par l'intermédiaire d'un ensemble mécanique qui se trouve, en fait, dans une position d'équilibre instable et qui, par conséquent, peut être aisément déséquilibré sous une impulsion de faible intensité. Aussi, pour donner cette impulsion, l'on a imaginé faire appel au ressort de rappel, finalement de faible raideur, qui ramène systématiquement le pêne demi-tour en position de verrouillage. En fait, en raison de cette faible raideur du ressort de rappel du pêne de verrouillage, celui-ci peut être aisément maintenu dans sa position déverrouillée ou semi-déverrouillée lorsque l'ouvrant est ouvert. Pour ce faire l'organe de retenue peut être de petite dimension et facilement actionné par le cadre dormant, plus particulièrement par la gâche avec laquelle est destiné à coopérer le pêne demi-tour au moment de refermer cet ouvrant. Finalement, la solution, selon l'invention, permet de répondre avantageusement au problème que posait jusqu'à présent la synchronisation des différentes pièces en mouvement au moment du verrouillage de porte.The advantages of the present invention consist of that the operating rod (s) are kept in their unlocked position, against the action of the means elastic to ensure their return to the position of locking, by means of a mechanical assembly which is, in fact, in an unstable equilibrium position and which, therefore, can be easily unbalanced under a low intensity pulse. Also, to give this impulse, we imagined using the return spring, finally of low stiffness, which systematically brings back the latch turn in the locked position. In fact, because of this low stiffness of the return spring of the bolt locking, it can be easily maintained in its unlocked or semi-unlocked position when opening is open. To do this, the retaining member can be small size and easily operated by the sleeping frame, more particularly by the keeper with which is intended to cooperate the latch bolt when closing this opening. Finally, the solution according to the invention makes it possible to respond advantageously to the problem posed so far by the synchronization of the different moving parts at the time door lock.

Tel que représenté dans la figure 1, la présente invention concerne une crémone ou crémone-serrure pour porte, porte-fenêtre ou analogue, comprenant, logé dans un boítier central 2, un mécanisme de commande 3 conçu apte à actionner au moins une tringle de manoeuvre 4, 4A.As shown in Figure 1, the present invention relates to a cremone bolt or bolt lock for door, French window or the like, comprising, housed in a central housing 2, a control mechanism 3 designed capable of actuating at least an operating rod 4, 4A.

A ce propos, l'on observera qu'une crémone ou crémone-serrure 1 peut être équipée d'une telle tringle de manoeuvre s'étendant au-dessus et/ou en-dessous dudit boítier central 2, tout comme elle peut être pourvue, comme représenté dans la figure 1, de deux tringles de manoeuvre 4, 4A se prolongeant, respectivement, au-dessus et en-dessous du boítier 2 et qui, au travers du mécanisme de commande 3, peuvent être amenés à se déplacer dans une même direction ou dans des directions opposées. Dans ce dernier cas de figure, ce mécanisme de commande 3 de la crémone ou crémone-serrure 1 intervient sur l'une des tringles de manoeuvre 4 par l'intermédiaire d'un inverseur de mouvement 5 connu par l'Homme du Métier et dont un mode de réalisation a été illustré, de manière schématisée, dans cette figure 1.In this regard, it will be observed that a cremone bolt or bolt lock 1 can be fitted with such an extending operating rod above and / or below said central box 2, just as it can be provided, as shown in Figure 1, with two maneuvering rods 4, 4A extending, respectively, above and below the housing 2 and which, at through the control mechanism 3, can be brought to move in the same direction or in directions opposite. In the latter case, this mechanism of command 3 of the cremone bolt or cremone bolt 1 intervenes on one of the operating rods 4 via a motion reverser 5 known to the skilled person and one of which embodiment has been illustrated schematically, in this figure 1.

De plus, ce mécanisme de commande 3 peut intervenir sur la ou les tringles de manoeuvre 4, 4A, soit directement ou encore au moyen d'un chevalet 6 logé dans le boítier 2 et raccordé à ses extrémités, par l'intermédiaire de moyens de liaison 7 appropriés, à cette ou ces tringles de manoeuvre 4, 4A.In addition, this control mechanism 3 can intervene on the or the operating rods 4, 4A, either directly or at by means of an easel 6 housed in the housing 2 and connected to its ends, by means of connecting means 7 suitable for this or these operating rods 4, 4A.

En fait, la présente invention s'attache, plus particulièrement, aux crémones ou crémones-serrures dont le mécanisme de commande 3 comporte, d'une part, des moyens élastiques 8 pour le rappel automatique en position de verrouillage de ces tringles de manoeuvre 4, 4A et, d'autre part, des moyens de commande manuels 9 pour permettre à l'usager d'assurer, manuellement, le déverrouillage de ces tringles de manoeuvre 4, 4A et le réarmement des moyens élastiques 8.In fact, the present invention is more in particular, with bolts or bolts and locks, the control mechanism 3 comprises, on the one hand, means elastic 8 for automatic return to position locking of these operating rods 4, 4A and, on the other hand, manual control means 9 to allow the user to manually unlock these operating rods 4, 4A and resetting the means elastic 8.

A ce propos, cette crémone ou crémone-serrure 1 comporte, encore, un dispositif de blocage 10 apte à maintenir, dans leur position déverrouillée, les tringles de manoeuvre 4, 4A après ouverture de l'ouvrant correspondant à la porte, porte-fenêtre ou analogue, ainsi que des moyens de déblocage 11 à même de désactiver ce dispositif de blocage 10 au moment de refermer l'ouvrant sur le cadre dormant et autoriser, de ce fait, le rappel en position de verrouillage desdites tringles de manoeuvre 4, 4A.In this regard, this cremone bolt or bolt lock 1 comprises, still, a blocking device 10 able to maintain, in their unlocked position, the operating rods 4, 4A after opening of the window corresponding to the door, French window or the like, as well as unlocking means 11 capable of deactivate this blocking device 10 when closing opening it on the frame and authorize, therefore, the return to the locking position of said rods of operation 4, 4A.

Selon un exemple de réalisation, non limitatif de la présente invention, lesdits moyens de commande manuels 9 sont constitués par un fouillot 12 comportant un logement 13 pour la réception d'un carré de manoeuvre d'une poignée de commande, ce fouillot 12 agissant sur les tringles de manoeuvre 4, 4A, notamment par l'intermédiaire du chevalet 6, à l'aide d'un organe d'entraínement 14 de configuration appropriée. Sur ce fouillot 12 peut encore être montée une couronne 15 munie d'un doigt d'entraínement 16 apte à intervenir sur la queue 17 d'un pêne demi-tour 18 repoussé dans sa position de verrouillage sous l'influence d'un ressort de rappel 19. According to an exemplary embodiment, without limitation of the present invention, said manual control means 9 are constituted by a follower 12 comprising a housing 13 for reception a control handle operating square, this follower 12 acting on the operating rods 4, 4A, in particular by through the easel 6, using an organ drive 14 of appropriate configuration. On this follower 12 can also be mounted a crown 15 provided with a finger 16 capable of working on the tail 17 of a bolt U-turn 18 pushed back into its locked position under the influence of a return spring 19.

A ce propos, des moyens de rappel élastiques 20 peuvent également intervenir sur le fouillot 12 pour ramener systématiquement celui-ci et, donc, la poignée de commande, dans une position de repos après une commande de verrouillage ou de déverrouillage.In this regard, elastic return means 20 can also intervene on the follower 12 to bring back systematically this and, therefore, the control handle, in a rest position after a locking command or unlocking.

Il convient encore de remarquer que de tels moyens de commande manuels 9 peuvent également servir d'assistance au moyen élastique 8 destiné à rappeler les tringles de manoeuvre 4, 4A dans leur position de verrouillage. Plus particulièrement lorsque ces tringles de manoeuvre 4, 4A rencontrent un obstacle résultant, par exemple, de la difficulté pour un organe de verrouillage, actionné par ces tringles de manoeuvre 4, 4A, d'entrer en coopération avec la gâche disposée en correspondance sur le cadre dormant, il se peut que la poussée exercée par ces moyens de rappel élastiques 8 soit alors insuffisante pour vaincre cet obstacle. A ce moment là, la manoeuvre peut être terminée à l'aide desdits moyens de commande manuels 9.It should also be noted that such control means textbooks 9 can also serve as assistance through elastic 8 intended to recall the operating rods 4, 4A in their locked position. More specifically when these operating rods 4, 4A encounter an obstacle resulting, for example, from the difficulty for an organ of locking, actuated by these operating rods 4, 4A, to enter into cooperation with the keeper arranged in correspondence on the sleeping frame, it may be that the thrust exerted by these elastic return means 8 or insufficient to overcome this obstacle. At that time, the maneuver can be completed using said means of manual control 9.

Dans le cadre d'une crémone-serrure, celle-ci reçoit, encore, un élément à clé 21 apte à intervenir, selon le cas, sur un pêne dormant 22 et/ou sur des moyens 23 de blocage des tringles de manoeuvre 4, 4A en position de verrouillage et/ou des moyens 24 de blocage en rotation du fouillot 12 dans le sens correspondant à une commande de déverrouillage.As part of a lock lever, it receives, again, a key element 21 capable of intervening, as the case may be, on a deadbolt 22 and / or on means 23 for locking the rods 4, 4A in the locking position and / or means 24 for blocking rotation of the follower 12 in the direction corresponding to an unlocking command.

Ceci précisé, selon une particularité de la présente invention, le dispositif de blocage 10, permettant de maintenir les tringles de manoeuvre 4, 4A dans leur position déverrouillée contre l'action des moyens élastiques 8, après ouverture de l'ouvrant, consiste en une genouillère 25. Celle-ci est composée d'au moins deux biellettes 26, 27 reliées à l'aide d'un pivot 28, au niveau de l'une de leurs extrémités, respectivement 26A, 27A, sachant que l'une 26 de ces biellettes est, en outre, à son autre extrémité opposée 26B, rendue solidaire par une articulation 29 des tringles de manoeuvre 4 ou 4A, en fait, du chevalet 6 relié à ces dernières. Quant à l'autre biellette 27, elle est rendue solidaire, à son extrémité 27B et par une articulation 30, du boítier 2. De plus, ces éléments sont ainsi disposés que, en position de déverrouillage des tringles de manoeuvre 4, 4A, le pivot 28 et les deux articulations 29, 30 de cette genouillère 25 viennent se situer, sensiblement, dans un même alignement 31 parallèle au déplacement 32 de ces tringles de manoeuvre 4, 4A ou encore du chevalet 6, pour venir étayer, notamment ce dernier, dans une position d'équilibre instable.That said, according to a feature of the present invention, the locking device 10, making it possible to maintain the operating rods 4, 4A in their unlocked position against the action of the elastic means 8, after opening of the opening, consists of a kneepad 25. This is composed of at least two links 26, 27 connected using a pivot 28, at one of their ends, respectively 26A, 27A, knowing that one 26 of these links is, in addition, at its other opposite end 26B, rendered secured by an articulation 29 of the operating rods 4 or 4A, in fact, the easel 6 connected to the latter. As for the other link 27, it is made integral, at its end 27B and by a joint 30, of the housing 2. Of more, these elements are so arranged that in the position of unlocking of the operating rods 4, 4A, the pivot 28 and the two joints 29, 30 of this toggle joint 25 come lie, substantially, in the same parallel alignment 31 displacement 32 of these operating rods 4, 4A or else bridge 6, to support, in particular the latter, in an unstable equilibrium position.

Avantageusement, cette crémone ou crémone-serrure 1, objet de l'invention, comporte en outre, des moyens d'assistance 33 pour garantir le maintien de cette genouillère 25 dans cette position d'équilibre instable pendant tout le temps où l'ouvrant de la porte, est ouvert et tant que cet équilibre instable n'est pas rompu volontairement par les moyens de déblocage 11 destinés, précisément, à désactiver le dispositif de blocage 10 au moment de refermer l'ouvrant sur son cadre dormant.Advantageously, this cremone bolt or bolt lock 1, the object of the invention further comprises assistance means 33 for guarantee that this toggle support 25 is maintained in this unstable equilibrium position all the time where the door opening, is open and as long as this balance unstable is not intentionally broken by means of release 11 intended, specifically, to deactivate the device blocking 10 when closing the door on its frame sleeping.

Selon un mode de réalisation préférentiel, ces moyens d'assistance 33 consistent en un ressort 34, de faible raideur, apte à maintenir, à hauteur du pivot 28, la genouillère 25, lorsque celle-ci est dans ladite position d'équilibre instable, en appui contre une butée 35 ménagée à cet effet à l'intérieur du boítier 2.According to a preferred embodiment, these means assistance 33 consist of a spring 34, of low stiffness, able to maintain, at the height of the pivot 28, the toggle joint 25, when the latter is in said unstable equilibrium position, bearing against a stop 35 provided for this purpose inside case 2.

Quant aux moyens de déblocage 11, tel que déjà précisé plus haut, ils sont pourvus aptes à briser cet équilibre instable de la genouillère 25, bien sûr dans une direction opposée à la butée 35, ceci au moment précis où l'ouvrant est refermé sur son cadre dormant en vue de permettre aux tringles de manoeuvre 4, 4A de regagner leur position de verrouillage automatiquement. Selon l'invention, les moyens de déblocage 11 consistent en un doigt de commande 36 associé à la queue 17 du pêne demi-tour 18 et qui, sous l'impulsion du ressort 19 destiné à rappeler ledit pêne demi-tour 18 dans sa position de verrouillage, est prévu apte à repousser la genouillère 25 de manière à décaler, légèrement le pivot 28 par rapport à l'alignement 31 des articulations 29, 30. Il en résulte, par rapport à ce pivot 28, un couple exercé par lesdites biellettes 26, 27 sous l'influence du chevalet 6 repoussé par les moyens élastiques 8.As for the unlocking means 11, as already specified more high, they are provided adept at breaking this unstable equilibrium of the knee brace 25 of course in a direction opposite to the stop 35, this at the precise moment when the opening is closed on its frame sleeping in order to allow the operating rods 4, 4A to return to their locked position automatically. According to the invention, the unlocking means 11 consist of a control finger 36 associated with the tail 17 of the latch turn 18 and which, under the impulse of the spring 19 intended to recall said U-bolt 18 to its position of locking, is provided capable of pushing the toggle switch 25 off so as to offset, slightly the pivot 28 relative to the alignment 31 of the joints 29, 30. This results, by relative to this pivot 28, a torque exerted by said links 26, 27 under the influence of the easel 6 repelled by the means elastic 8.

En fait, de tels moyens de déblocage 11 sont encore complétés par un organe de retenue 37 apte à retenir le pêne demi-tour 18 dans une position déverrouillée ou semi-verrouillée lorsque l'ouvrant est ouvert. Cet organe de retenue 37, rappelé, automatiquement dans une position active sous l'influence d'un ressort de rappel 38, est en outre prévu pour être commandé et donc désactivé pour libérer ledit pêne demi-tour 18 par le cadre dormant, préférentiellement la gâche équipant ce dernier et destinée à accueillir ledit pêne demi-tour 18.In fact, such unlocking means 11 are further supplemented. by a retaining member 37 capable of retaining the latch bolt 18 in an unlocked or semi-locked position when the opening is open. This retaining member 37, recalled, automatically in an active position under the influence of a return spring 38, is furthermore intended to be ordered and therefore deactivated to release said latch bolt 18 by the sleeping frame, preferably the keeper fitted to the latter and intended to accommodate said latch bolt 18.

Selon un mode de réalisation avantageux, cet organe de retenue 17 est directement intégré à la tête 18A du pêne demi-tour 18 et se présente sous forme d'un levier 39 logé dans une rainure 40 ménagée au niveau de la face dorsale 50, opposée à celle biaisée 51 de cette tête 18A du pêne demi-tour 18. Cette rainure 40 et donc ledit levier 39 s'étendent, parallèlement au déplacement de ce dernier. En fait, ce levier 39 est monté de manière pivotante dans cette rainure 40, autour d'un axe 52 vertical, perpendiculaire au déplacement dudit pêne demi-tour 18.According to an advantageous embodiment, this retaining member 17 is directly integrated into the head 18A of the latch bolt 18 and is in the form of a lever 39 housed in a groove 40 formed at the dorsal face 50, opposite to that biased 51 of this head 18A of the latch bolt 18. This groove 40 and therefore said lever 39 extend parallel to the displacement of the latter. In fact, this lever 39 is mounted pivotally in this groove 40, about an axis 52 vertical, perpendicular to the movement of said latch bolt 18.

De plus, au niveau du bord externe 53 de ce levier 39, est ménagée une découpe 54 apte à coopérer, en position active de cet organe de retenue 37, avec un rebord de retenue 55 prévu à cet effet au niveau du boítier 2.In addition, at the outer edge 53 of this lever 39, is formed a cutout 54 capable of cooperating, in the active position of this retaining member 37, with a retaining flange 55 provided at this effect at the housing 2.

Finalement, ledit levier 39 est prolongé, au-delà de son axe de pivotement 52, par un retour 56 sur lequel vient agir le ressort de rappel 38 sous forme, préférentiellement, d'un ressort à lame fixé à l'arrière de la tête 18A du pêne demi-tour 18. La forme de ce ressort à lames 38 a été représentée dans la figure 5.Finally, said lever 39 is extended, beyond its axis of pivot 52, by a return 56 on which the return spring 38 in the form, preferably, of a leaf spring fixed to the rear of the head 18A of the latch bolt 18. The shape of this leaf spring 38 has been shown in figure 5.

En fait, l'on observera que ce retour 56 prolongeant le levier 39 au-delà de son axe de pivotement 52 vient, lui aussi, se loger dans une rainure 57 laquelle s'étend dans ce cas, à l'arrière de ladite tête 18A du pêne demi-tour 18. Le fond de cette rainure 57 sert de butée contre laquelle le retour 56 est appliqué sous l'impulsion du ressort à lame 38 correspondant à la position active de l'organe de retenue 37.In fact, it will be observed that this return 56 extending the lever 39 beyond its pivot axis 52 also comes lodge in a groove 57 which in this case extends to the rear of said head 18A of the latch bolt 18. The bottom of this groove 57 serves as a stop against which the return 56 is applied under the impulse of leaf spring 38 corresponding to the active position of the retaining member 37.

De plus, pour permettre à l'organe de retenue 37 de s'effacer lors du recul du pêne demi-tour 18, le bord externe 53 du levier 39 en regard avec le rebord de retenue 55, est de forme définie sans redan pour autoriser cette manoeuvre.In addition, to allow the retaining member 37 to fade during the retraction of the latch bolt 18, the outer edge 53 of the lever 39 facing the retaining rim 55, is shaped defined without steps to authorize this maneuver.

Finalement, le levier 39 est encore conçu apte à coopérer avec le cadre dormant, plus particulièrement, la gâche destinée à accueillir le pêne demi-tour 18, au moment de refermer l'ouvrant, en vue de libérer le pêne demi-tour 18. Aussi, ce levier 39 comporte, le long de sa partie 58 restant dans tous les cas saillante par rapport au chant avant du boítier 2, un doigt de commande 59 sous forme d'un bossage au niveau de son bord externe 53. En fait, ce doigt de commande 59 se présente saillant par rapport à la face dorsale 50 de la tête 18A du pêne demi-tour 18 et est orienté, par conséquent, en direction dudit cadre dormant de la porte. Finally, the lever 39 is still designed capable of cooperating with the sleeping frame, more particularly, the keeper intended for receive the latch 18, when closing opening it, in order to release the latch bolt 18. Also, this lever 39 comprises, along its part 58 remaining in all the salient cases with respect to the front edge of the housing 2, a control finger 59 in the form of a boss at the level of its outer edge 53. In fact, this control finger 59 presents itself protruding from the dorsal face 50 of the head 18A of the latch turn 18 and is oriented, therefore, towards of said door frame.

Ainsi, le mode de fonctionnement d'une telle crémone ou crémone-serrure 1, partant de la position de verrouillage adoptée lorsque la porte ou fenêtre est fermée, consiste, le cas échéant après déverrouillage de l'élément à clé 21, à actionner les moyens de commande 9 d'où résulte le déverrouillage des tringles de manoeuvre 4, 4A et le réarmement des moyens élastiques 8 tandis que la genouillère 25 est amenée dans sa position d'équilibre instable résultant de l'alignement de son pivot 28 avec les articulations 29, 30. Cette genouillère 25 est alors maintenue dans cette position d'équilibre instable au travers des moyens d'assistance 33 que définit le ressort 34 apte à maintenir le pivot 28 de la genouillère 25 contre la butée 35.Thus, the mode of operation of such a lever or lock-bolt 1, starting from the locking position adopted when the door or window is closed, consists of if necessary after unlocking the key element 21, at activate the control means 9 from which the unlocking of operating rods 4, 4A and resetting elastic means 8 while the toggle 25 is brought in its unstable equilibrium position resulting from alignment of its pivot 28 with the joints 29, 30. This knee brace 25 is then held in this position of unstable equilibrium through assistance means 33 that defines the spring 34 capable of holding the pivot 28 of the toggle 25 against the stop 35.

En fait, l'action exercée à cet instant par l'usager sur la poignée de commande et donc sur le fouillot 12 que définit, substantiellement, les moyens de commande manuels 9, conduit, également, au recul du pêne demi-tour 18 de sorte que l'ouvrant peut être ouvert à ce moment là.In fact, the action exerted at this moment by the user on the control handle and therefore on the follower 12 that defines, substantially, the manual control means 9, leads, also, at the back of the latch bolt 18 so that the opening can be opened at this time.

Lorsque l'usager vient à relâcher son action sur ladite poignée de commande, le pêne demi-tour 18, sous l'impulsion du ressort 19 tente de regagner sa position de verrouillage. Intervient, alors, l'organe de retenue 37 qui, étant maintenu en position active par le ressort de rappel 38, vient coopérer avec le rebord de retenue 55 ménagé au niveau du boítier 2 pour retenir ledit pêne demi-tour 18 dans sa position déverrouillée ou, préférentiellement, semi-déverrouillée.When the user comes to relax his action on said handle control, the latch bolt 18, driven by the spring 19 attempts to regain its locked position. Speaks, then, the retaining member 37 which, being held in position activated by the return spring 38, cooperates with the retaining rim 55 formed at the level of the housing 2 for retaining said U-bolt 18 in its unlocked position or, preferably, semi-unlocked.

Au moment de refermer l'ouvrant sur le cadre dormant, l'action de la gâche sur la face biaisée 51 du pêne demi-tour 18 produit, tout d'abord, le recul de ce dernier. Puis, lorsque ce pêne demi-tour 18 est à même de pénétrer dans cette gâche, celle-ci vient actionner, automatiquement le doigt de commande 59 du levier 39 de manière à rendre l'organe de retenue 37 inactif permettant à ce pêne demi-tour 18 d'atteindre sa position totalement verrouillée, amenant le doigt de commande 36 solidaire de la queue 17 de ce pêne demi-tour à repousser la genouillère 25 et, donc, à la décaler par rapport à la position d'équilibre instable qu'elle occupait, ce qui vient libérer les moyens élastiques 8 assurant, par là même, le rappel en position de verrouillage des tringles de manoeuvre 4, 4A.When closing the door on the sleeping frame, the action strike plate on the biased face 51 of the latch bolt 18 produced, first of all, the decline of the latter. Then when this U-bolt 18 is able to enter this strike, it activates the control finger automatically 59 of the lever 39 so as to make the retaining member 37 inactive allowing this latch bolt 18 to reach its fully locked position, bringing the control finger 36 secured to the tail 17 of this latch bolt to repel the knee brace 25 and, therefore, to offset it from the position of unstable equilibrium which it occupied, which comes to free the elastic means 8 thereby ensuring the return to locking position of the operating rods 4, 4A.
