Description

La présente invention a trait à une crémone pour un système de verrouillage d'un dispositif de fermeture.The present invention relates to a cremone for a locking system of a closure device.

Cette invention concerne le domaine du bâtiment et, plus particulièrement, celui de la fabrication de la quincaillerie destinée à équiper un dispositif de fermeture d'une ouverture d'une construction comme une porte, une fenêtre, une porte-fenêtre ou analogue. This invention relates to the field of the building and, more particularly, that of the manufacture of hardware for fitting a closing device of an opening of a construction such as a door, a window, a French window or the like.

L'on connait, d'ores et déjà, des telles crémones pour un système de verrouillage d'un dispositif de fermeture.Known already, such cremones for a locking system of a closure device.

Une telle crémone comporte un boîtier destiné à être positionné à l'intérieur d'un logement que comporte le dispositif de fermeture, plus particulièrement l'ouvrant d'un tel dispositif de fermeture. Cette crémone comporte, également, un fouillot, monté au moins en rotation à l'intérieur du boîtier, ceci selon un axe de rotation ainsi qu'entre une position de déverrouillage et une position de verrouillage. Ce fouillot comporte une denture ainsi qu'une ouverture pour recevoir un carré de transmission. Ladite crémone comporte, encore, une tringle, mobile en translation par rapport au boîtier selon une direction de translation, ceci entre une position de déverrouillage et une position de verrouillage. Cette tringle comporte une crémaillère en prise avec la denture du fouillot, ceci pour un entraînement en translation de cette tringle sous l'impulsion d'une rotation du fouillot. Cette tringle comporte ou est reliée à une tringle de manoeuvre qui comporte au moins un organe de verrouillage conçu pour coopérer avec au moins une gâche, que comporte le système de verrouillage, et qui équipe, plus particulièrement, le dormant du dispositif de fermeture.Such cremone comprises a housing intended to be positioned inside a housing that includes the closure device, more particularly the opening of such a closure device. This cremone also comprises a follower, mounted at least in rotation inside the housing, this along an axis of rotation and between an unlocking position and a locking position. This nut has a toothing and an opening for receiving a transmission square. Said cremone further comprises a rod movable in translation relative to the housing in a translation direction, this between an unlocking position and a locking position. This rod comprises a rack engaged with the toothing of the follower, this for a drive in translation of this rod under the impulse of a rotation of the follower. This rod comprises or is connected to an operating rod which comprises at least one locking member designed to cooperate with at least one striker, which comprises the locking system, and which equips, more particularly, the frame of the closure device.

Lors d'une tentative d'effraction, un individu est susceptible d'exercer une contrainte directement sur la tringle ou sur les organes de verrouillage, ceci par l'intermédiaire d'un outil comme un tournevis ou analogue. Cette contrainte a pour effet de provoquer le déplacement de la tringle hors de sa position de verrouillage et dans sa position de déverrouillage. Il en résulte un déverrouillage du système de verrouillage ce qui permet l'ouverture du dispositif de fermeture.During an attempted break-in, an individual is likely to exert a stress directly on the rod or on the locking members, this by means of a tool such as a screwdriver or the like. This constraint for effect to cause the movement of the rod out of its locking position and in its unlocking position. This results in an unlocking of the locking system which allows the opening of the closure device.

Dans le cas particulier des dispositifs de fermeture conçus pour autoriser un maintien temporaire de l'ouvrant dans différentes positions préférentielles (ouvert, fermé, entrebâillé ou encore oscillo-battant, ouvert à la française, fermé), il est usuel de faire appel à des moyens additionnels élastiques liés aux moyens de verrouillage, ceci pour réaliser les fonctions de maintien temporaire dans ces différentes positions. Cependant, pour éviter à un utilisateur d'exercer des efforts de manoeuvre disproportionnés à chaque manoeuvre d'ouverture ou de fermeture, ces moyens élastiques présentent une capacité de maintien limitée. Il a, donc, été nécessaire de compléter ces dispositifs de fermeture avec des moyens antieffraction, qui immobilisent temporairement les moyens de verrouillage dans des positions adoptées par ces moyens de verrouillage lorsque l'ouvrant adopte les positions préférentielles, et qui s'opposent à tout mouvement ou à toute tentative d'ouverture qui résulterait d'une contrainte exercée directement sur ces moyens de verrouillage dans le cadre d'une effraction. Cependant, ces moyens antieffraction présentent de nombreux inconvénients. En particulier, ces moyens antieffraction font appel à de nombreux composants de sorte qu'ils sont particulièrement complexes. Ces moyens antieffraction peuvent, également, mettre en oeuvre des frottements importants de glissement sous charge entre les composants des moyens de verrouillage ce qui pénalise les manoeuvres d'ouverture et de fermeture.In the particular case of closing devices designed to allow a temporary holding of the opening in different preferred positions (open, closed, ajar or alternatively tilt-and-turn, open to the French, closed), it is customary to call upon additional elastic means related to the locking means, this to perform the temporary holding functions in these different positions. However, to prevent a user from exerting disproportionate maneuvering forces at each opening or closing maneuver, these elastic means have a limited holding capacity. It has therefore been necessary to complete these closure devices with anti-interference means, which temporarily immobilize the locking means in positions adopted by these locking means when the opening adopts the preferred positions, and which oppose any movement or any attempt to open that would result from a constraint exerted directly on these locking means in the context of a break-in. However, these anti-bursting means have many disadvantages. In particular, these anti-bursting means make use of many components so that they are particularly complex. These anti-bursting means can also implement significant sliding friction under load between the components of the locking means which penalizes the opening and closing maneuvers.

La présente invention se veut de remédier aux inconvénients des crémones de l'état de la technique.The present invention aims to overcome the disadvantages of the espagnolettes of the state of the art.

A cet effet, l'invention concerne une crémone pour un système de verrouillage d'un dispositif de fermeture d'une ouverture d'une construction.To this end, the invention relates to a cremone for a locking system of a closing device of an opening of a construction.

Cette crémone comporte, d'une part, un boîtier, d'autre part, un fouillot, monté au moins en rotation à l'intérieur du boîtier selon un axe de rotation ainsi qu'entre une position de déverrouillage et une position de verrouillage, et comportant une denture ainsi qu'une ouverture pour recevoir un carré de transmission et, d'autre part encore, une tringle, mobile en translation par rapport au boîtier selon une direction de translation, et comportant une crémaillère en prise avec la denture du fouillot.This cremone comprises, on the one hand, a housing, on the other hand, a follower, mounted at least in rotation inside the housing along an axis of rotation and between an unlocking position and a locking position, and having a toothing and an opening for receiving a transmission square and, secondly, a rod, movable in translation relative to the housing in a translational direction, and having a rack engaged with the toothing of the follower .

Cette crémone est caractérisée par le fait que, d'une part, elle comporte des moyens de logement pour loger le carré de transmission à l'intérieur de l'ouverture du fouillot, ceci avec un jeu transversal selon une direction transversale par rapport à l'axe de rotation du fouillot, d'autre part, elle comporte des moyens de montage pour monter le fouillot à l'intérieur du boîtier, ceci avec un jeu longitudinal selon une direction parallèle à la direction de translation de la tringle et, d'autre part encore, elle est configurée en sorte que, lorsque le fouillot est en position de verrouillage, le jeu transversal et le jeu longitudinal s'étendent selon une même direction, ceci pour autoriser un déplacement en translation du fouillot par rapport au boîtier.This espagnolette is characterized in that, on the one hand, it comprises housing means for housing the transmission square inside the opening of the follower, this with a transverse clearance in a transverse direction relative to the the axis of rotation of the follower, on the other hand, it comprises mounting means for mounting the follower inside the housing, this with a longitudinal clearance in a direction parallel to the direction of translation of the rod and, d ' still further, it is configured so that, when the follower is in the locking position, the transverse play and the longitudinal play extend in the same direction, this to allow a translational movement of the follower relative to the housing.

Une autre caractéristique de l'invention consiste en ce que les moyens de logement sont constitués par l'ouverture, que comporte le fouillot, qui présente une forme rectangulaire, et qui comporte, d'une part, des petits côtés qui présentent une longueur sensiblement égale à celle des côtés du carré de transmission et, d'autre part, des grands côtés qui présentent une longueur supérieure à celle des petits côtés de l'ouvertureAnother feature of the invention consists in that the housing means are constituted by the opening, which comprises the follower, which has a rectangular shape, and which comprises, on the one hand, small sides which have a substantially equal to that of the sides of the transmission square and, on the other hand, long sides which have a length greater than that of the short sides of the opening

Une caractéristique additionnelle concerne le fait que les moyens de montage comportent, d'une part, au moins un moyeu, que comporte latéralement le fouillot, et qui adopte une forme circulaire et, d'autre part, au moins un logement, que comporte le boîtier, qui adopte une forme oblongue, qui s'étend selon un axe parallèle à la direction de translation de la tringle, et à l'intérieur duquel s'étend ledit au moins un moyeu.An additional feature relates to the fact that the mounting means comprise, on the one hand, at least one hub, which laterally comprises the follower, and which adopts a circular shape and, on the other hand, at least one housing, that includes the housing, which adopts an oblong shape, which extends along an axis parallel to the translation direction of the rod, and within which extends said at least one hub.

De plus, le jeu transversal est au moins égal au jeu longitudinal.In addition, the transverse clearance is at least equal to the longitudinal clearance.

L'invention concerne, également, un système de verrouillage pour un dispositif de fermeture d'une ouverture d'une construction, ce système de verrouillage comportant une crémone et un carré de transmission. Ce système de verrouillage est caractérisé par le fait que la crémone présente les caractéristiques décrites ci-dessus.The invention also relates to a locking system for a device for closing an opening of a construction, this locking system comprising a espagnolette and a transmission square. This locking system is characterized in that the espagnolette has the characteristics described above.

Ainsi, dans cette crémone, le carré de transmission est logé à l'intérieur de l'ouverture du fouillot avec un jeu transversal tandis que ce fouillot est logé à l'intérieur du boîtier avec un jeu longitudinal. En position de verrouillage du fouillot, le jeu transversal et le jeu longitudinal s'étendent dans la même direction ce qui autorise une translation du fouillot par rapport au boîtier. Aussi, dans le cadre d'une effraction, une contrainte d'effraction, exercée directement sur la tringle ou sur un organe de verrouillage associé à cette tringle, a pour effet de provoquer une telle translation, par rapport au boîtier, du fouillot qui adopte, alors, une position de blocage en rotation. Un tel blocage en rotation du fouillot empêche, avantageusement et lorsqu'une contrainte d'effraction est exercée, un déplacement en translation, de la position de verrouillage vers la position de déverrouillage, de la tringle et, donc, de l'organe de verrouillage. Ce dernier reste, donc et malgré une telle contrainte d'effraction, dans une position de verrouillage ce qui permet de garantir le verrouillage du système de verrouillage et, donc, du dispositif de fermeture.Thus, in this espagnolette, the transmission square is housed inside the opening of the follower with a transverse clearance while the follower is housed inside the housing with a longitudinal clearance. In the locking position of the follower, the transverse play and the longitudinal play extend in the same direction which allows a translation of the follower relative to the housing. Also, in the context of a break-in, a burglary stress, exerted directly on the rod or on a locking member associated with this rod, has the effect of causing such a translation, with respect to the housing, the follower who adopts , then, a locking position in rotation. Such blockage in rotation of the follower prevents, advantageously and when a burglary stress is exerted, a displacement in translation, from the locking position to the unlocking position, of the rod and, therefore, of the locking member . The latter remains, therefore and despite such burglary, in a locking position which ensures the locking of the locking system and, therefore, the closure device.

On observera que ce résultat est atteint grâce aux caractéristiques techniques particulières de la crémone conforme à la présente invention. En fait, ces caractéristiques techniques particulières concernent des aménagements spécifiques (jeu transversal et jeu longitudinal) et astucieux que présentent des éléments traditionnels (le fouillot et le boitier) que comporte une crémone. Aussi et de manière avantageuse, la crémone selon l'invention intègre des éléments traditionnels mais qui présentent, cependant, de tels aménagements.It will be observed that this result is achieved thanks to the special technical features of the espagnolette according to the present invention. In fact, these particular technical characteristics concern specific arrangements (transverse play and longitudinal play) and clever that present traditional elements (the follower and the box) that includes a cremone. Also and advantageously, the cremone according to the invention incorporates elements traditional, but which, however, present such developments.

Un autre avantage consiste en ce que la crémone conforme à l'invention intègre un nombre limité de pièces (notamment le même nombre de pièces qu'une crémone traditionnelle dépourvue de moyens antieffraction spécifiques) et constitue, donc, une simplification notable par rapport aux crémones antieffraction de l'état de la technique.Another advantage is that the espagnolette according to the invention incorporates a limited number of parts (including the same number of parts as a traditional espagnolette devoid of specific anti-burglary means) and is, therefore, a significant simplification compared to cremones anti-interference of the state of the art.

Encore un autre avantage consiste en ce que la crémone conforme à l'invention, de par ses caractéristiques techniques particulières, n'occasionne pas de frottements de glissement sous charge qui pourraient pénaliser la manipulation du dispositif de fermeture.Yet another advantage is that the cremone according to the invention, because of its particular technical characteristics, does not cause sliding friction under load that could penalize the handling of the closure device.

Finalement et étant donné que la crémone selon l'invention intègre des éléments traditionnels (bien que présentant des aménagés), cette crémone est susceptible de se substituer facilement et à moindres frais à des crémones classiques, voire de remplacer de telles crémones, notamment dans le cadre d'une rénovation ou d'une amélioration de la sécurité d'une construction.Finally and since the cremone according to the invention incorporates traditional elements (although having developed), this cremone is likely to easily and cheaply replace conventional espagnolette bolts, or even to replace such cremones, especially in the part of a renovation or improvement of the safety of a construction.

La présente invention concerne le domaine du bâtiment et, plus particulièrement, celui de la fabrication de la quincaillerie destinée à équiper un dispositif de fermeture d'une ouverture d'une construction comme une porte, une fenêtre, une porte-fenêtre ou analogue.The present invention relates to the field of the building and, more particularly, that of the manufacture of hardware for fitting a closing device of an opening of a construction such as a door, a window, a French window or the like.

L'invention concerne, alors, plus particulièrement, une crémone 1 pour un système de verrouillage 2 d'un tel dispositif de fermeture d'une ouverture d'une construction.The invention relates, more particularly, to a cremone 1 for a locking system 2 of such a device for closing an opening of a construction.

Une telle crémone 1 comporte un boîtier 3 destiné à être positionné à l'intérieur d'un logement que comporte ledit dispositif de fermeture, plus particulièrement l'ouvrant d'un tel dispositif de fermeture.Such cremone 1 comprises a housing 3 intended to be positioned inside a housing that includes said closure device, more particularly the opening of such a closure device.

Cette crémone 1 comporte, également, un fouillot 4, monté au moins en rotation à l'intérieur du boîtier 3, ceci selon un axe de rotation ainsi qu'entre une position de déverrouillage (figures 1 et 2) et une position de verrouillage (figures 3 à 6) .This cremone 1 also comprises a follower 4, mounted at least in rotation inside the housing 3, this along an axis of rotation and between an unlocking position ( Figures 1 and 2 ) and a locking position ( Figures 3 to 6 ).

Ce fouillot 4 comporte, d'une part, une denture 40, qui comporte au moins une dent (voire une pluralité de dents tel que visible sur les figures en annexe), et qui équipe la périphérie de ce fouillot 4 et, d'autre part, une ouverture 41, notamment traversante, configurée pour recevoir un carré de transmission 5 que comporte le système de verrouillage 2.This follower 4 comprises, on the one hand, a toothing 40, which comprises at least one tooth (or even a plurality of teeth as visible in the appended figures), and which equips the periphery of this follower 4 and, on the other hand on the other hand, an opening 41, in particular a through opening, configured to receive a transmission square 5 that comprises the locking system 2.

La crémone 1 comporte, également, une tringle 6 qui peut être constituée par une tringle de manoeuvre comportant au moins un organe de verrouillage (non représenté) conçu pour coopérer avec au moins une gâche (non représentée), que comporte le système de verrouillage 2, et qui équipe, plus particulièrement, le dormant du dispositif de fermeture. De manière alternative, cette tringle 6 peut encore être constituée par une tringle de transmission en prise avec une telle tringle de manoeuvre.The espagnolette 1 also comprises a rod 6 which may consist of an operating rod comprising at least one locking member (not shown) designed to cooperate with at least one striker (not shown), which comprises the locking system 2 and which equips, more particularly, the frame of the closing device. Alternatively, this rod 6 may also be constituted by a transmission rod engaged with such an operating rod.

Quoi qu'il en soit, cette tringle 6 s'étend au moins en partie à l'intérieur du boîtier 3, plus particulièrement à l'arrière d'une têtière 30 qui referme un tel boîtier 3. Cette tringle 6 est mobile en translation par rapport à ce boîtier 3, ceci selon une direction de translation T ainsi qu'entre une position de déverrouillage (figures 1 et 2) et une position de verrouillage (figures 3 à 6).Anyway, this rod 6 extends at least partially inside the housing 3, particularly at the rear of a headrest 30 which closes such a housing 3. This rod 6 is movable in translation relative to this housing 3, this in a translation direction T as well as between an unlocking position ( Figures 1 and 2 ) and a locking position ( Figures 3 to 6 ).

Cette tringle 6 comporte une crémaillère 60 en prise avec la denture 40 du fouillot 4. En fait, cette crémaillère 60 comporte au moins un creux (voire une pluralité de creux) ou (et de préférence) au moins une ouverture 61 (voire une pluralité d'ouvertures comme visible sur les figures en annexe) qui coopèrent avec la ou les dents de la denture 40 du fouillot 4 ceci pour, sous l'impulsion d'une rotation de ce fouillot 4, entraîner la tringle 6 en translation selon la direction de translation T, entre la position de déverrouillage et la position de verrouillage.This rod 6 comprises a rack 60 engaged with the toothing 40 of the follower 4. In fact, this rack 60 comprises at least one hollow (or a plurality of depressions) or (and preferably) at least one opening 61 (or a plurality of openings as visible in the appended figures) which cooperate with the tooth or teeth of the toothing 40 of the follower 4, in order to drive the rod 6 in translation in the direction, under the impulse of a rotation of this follower 4 translation T, between the unlocking position and the locking position.

Selon l'invention, la crémone 1 comporte des moyens de logement 7 pour loger le carré de transmission 5 à l'intérieur de l'ouverture 41 du fouillot 4, ceci avec un jeu transversal 8 selon une direction transversale par rapport à l'axe de rotation du fouillot 4.According to the invention, the espagnolette 1 comprises housing means 7 for housing the transmission square 5 inside the opening 41 of the follower 4, this with a transverse clearance 8 in a direction transverse to the axis rotation of the follower 4.

De plus, cette crémone 1 comporte des moyens de montage 9 pour monter le fouillot 4 à l'intérieur du boîtier 3, ceci avec un jeu longitudinal 10 selon une direction parallèle à la direction de translation T de la tringle 6.In addition, this cremone 1 comprises mounting means 9 for mounting the follower 4 inside the housing 3, this with a longitudinal clearance 10 in a direction parallel to the translation direction T of the rod 6.

Cette crémone 1 est, alors, configurée en sorte que, lorsque le fouillot 4 est en position de verrouillage (figures 3 à 6), le jeu transversal 8 et le jeu longitudinal 10 s'étendent selon une même direction (à savoir une direction parallèle à la direction de translation T de la tringle 6), ceci pour autoriser un déplacement en translation du fouillot 4 par rapport au boîtier 3, entre une position de déblocage en rotation (figures 3 et 4) et une position de blocage en rotation (figures 5 et 6) de ce fouillot 4.This cremone 1 is then configured so that when the follower 4 is in the locking position ( Figures 3 to 6 ), the transverse clearance 8 and the longitudinal clearance 10 extend in the same direction (namely a direction parallel to the translation direction T of the rod 6), to allow a displacement in translation of the follower 4 relative to the housing 3, between a unlocking position in rotation ( Figures 3 and 4 ) and a locking position in rotation ( Figures 5 and 6 ) of this follower 4.

A ce propos, on observera que, lorsque le fouillot 4 et la tringle 6 sont dans la position de verrouillage, une contrainte C (notamment d'effraction) exercée sur la tringle 6 et/ou sur un organe de verrouillage provoque le déplacement en translation de cette tringle 6 (figure 5), ceci selon la direction de translation T, à partir de la position de verrouillage et en direction d'une position de déverrouillage de la tringle 6. Sous l'effet de la coopération entre la crémaillère 60 de la tringle 6 et la denture 40 du fouillot 4, ce déplacement en translation de la tringle 6 provoque le déplacement en translation du fouillot 4 (adoptant une position de verrouillage) par rapport au boîtier 3, ceci à partir d'une position de déblocage en rotation de ce fouillot 4 (figures 3 et 4) et pour un positionnement de ce fouillot 4 dans une position de blocage en rotation de ce fouillot 4 par rapport au boîtier 3 (figures 5 et 6). Dans cette position de blocage en rotation du fouillot 4, le blocage en rotation de ce fouillot 4 empêche la tringle 6 d'entraîner ce fouillot 4 en rotation ce qui empêche le déplacement de cette tringle 6 en translation et, par conséquent, le déplacement de l'organe de verrouillage hors de sa position de verrouillage. Il en découle que l'organe de verrouillage est maintenu dans sa position de verrouillage ce qui permet de garantir le verrouillage du système de verrouillage 2 et, par conséquent, le verrouillage du dispositif de fermeture.In this respect, it will be observed that, when the follower 4 and the bead wire 6 are in the locking position, a stress C (in particular breaking) exerted on the bead wire 6 and / or on a locking member causes the displacement in translation. of this rod 6 ( figure 5 ), this in the direction of translation T, from the locking position and towards an unlocking position of the rod 6. Under the effect of the cooperation between the rack 60 of the rod 6 and the toothing 40 4, this displacement in translation of the rod 6 causes the displacement in translation of the follower 4 (adopting a locking position) relative to the housing 3, this from a rotational unlocking position of the follower 4 ( Figures 3 and 4 ) and for positioning this follower 4 in a rotational locking position of this follower 4 relative to the housing 3 (FIG. Figures 5 and 6 ). In this rotational locking position of the follower 4, the locking in rotation of the follower 4 prevents the rod 6 from driving the follower 4 in rotation which prevents the displacement of the rod 6 in translation and, consequently, the displacement of the locking member out of its locking position. It follows that the locking member is held in its locking position which ensures the locking of the locking system. locking 2 and, therefore, locking the closure device.

Tel que mentionné ci-dessus, la crémone 1 comporte des moyens de logement 7 pour loger le carré de transmission 5 à l'intérieur de l'ouverture 41 du fouillot 4, ceci avec un jeu transversal 8 selon une direction transversale par rapport à l'axe de rotation du fouillot 4.As mentioned above, the espagnolette 1 comprises housing means 7 for housing the transmission square 5 inside the opening 41 of the follower 4, this with a transverse clearance 8 in a direction transverse to the rotation axis of the follower 4.

Selon un mode préféré de réalisation, ces moyens de logement 7 sont constitués par l'ouverture 41, que comporte le fouillot 4, et qui présente une forme rectangulaire. En fait, on observera que cette ouverture 41 comporte, alors, d'une part, des petits côtés 410 qui présentent une longueur sensiblement égale à celle des côtés 50 du carré de transmission 5 mais configurée pour autoriser un déplacement de ce carré de manoeuvre 5 à l'intérieur de cette ouverture 41. D'autre part, cette ouverture 41 comporte des grands côtés 411 qui présentent une longueur supérieure à celle des petits côtés 410 de l'ouverture 41.According to a preferred embodiment, these housing means 7 are constituted by the opening 41, which comprises the follower 4, and which has a rectangular shape. In fact, it will be observed that this opening 41 comprises, then, on the one hand, short sides 410 which have a length substantially equal to that of the sides 50 of the transmission square 5 but configured to allow movement of this square maneuver 5 inside this opening 41. On the other hand, this opening 41 has long sides 411 which have a length greater than that of the short sides 410 of the opening 41.

A ce propos, on observera que la différence de longueur entre les grands côtés 411 et les petits côtés 410 de l'ouverture 41 du fouillot 4 correspond, en fait, au jeu transversal 8.In this regard, it will be observed that the difference in length between the long sides 411 and the short sides 410 of the opening 41 of the follower 4 corresponds, in fact, to the transverse clearance 8.

Tel que mentionné ci-dessus, la crémone 1 comporte des moyens de montage 9 pour monter le fouillot 4 à l'intérieur du boîtier 3, ceci avec un jeu longitudinal 10 selon une direction parallèle à la direction de translation T de la tringle 6.As mentioned above, the espagnolette 1 comprises mounting means 9 for mounting the follower 4 inside the housing 3, this with a longitudinal clearance 10 in a direction parallel to the translation direction T of the rod 6.

A ce propos, il convient d'observer que ces moyens de montage 9 comportent, d'une part, au moins un moyeu 42, que comporte latéralement le fouillot 4, et qui adopte une forme circulaire et, d'autre part, au moins un logement 31, que comporte le boîtier 3, qui adopte une forme oblongue, qui s'étend selon un axe parallèle à la direction de translation T de la tringle 6, et à l'intérieur duquel s'étend ledit au moins un moyeu 42.In this regard, it should be noted that these mounting means 9 comprise, on the one hand, at least one hub 42, which laterally comprises the follower 4, and which adopts a circular shape and, on the other hand, at least a housing 31, which comprises the housing 3, which adopts an oblong shape, which extends along an axis parallel to the translation direction T of the rod 6, and within which extends said at least one hub 42 .

Selon un mode de réalisation préféré illustré sur les figures en annexe, ces moyens de montage 9 comportent, en fait, d'une part, deux moyeux 42, que comporte le fouillot 4 latéralement et de part et d'autre, et qui adoptent chacun une forme circulaire et, d'autre part, deux logements 31, que comporte de part et d'autre le boîtier 3, qui adoptent chacun une forme oblongue, qui s'étendent chacun selon un axe parallèle à la direction de translation T de la tringle 6, et à l'intérieur desquels s'étendent lesdits moyeux 42.According to a preferred embodiment illustrated in the appended figures, these mounting means 9 comprise, in fact, on the one hand, two hubs 42, which has the follower 4 laterally and on both sides, and which each adopt a circular shape and, secondly, two housings 31, which comprises on both sides the 3, which each adopt an oblong shape, each extending along an axis parallel to the translation direction T of the rod 6, and within which extend said hubs 42.

Ainsi, les moyens de montage 9 comportent, avantageusement, au moins un moyeu 42 de forme circulaire. A ce propos, il convient d'observer que ce ou ces moyeux 42 présentent, chacun, un centre traversé par l'axe de rotation du fouillot 4. De plus, un tel moyeu 42 présente un rayon déterminé.Thus, the mounting means 9 advantageously comprise at least one hub 42 of circular shape. In this regard, it should be noted that this or these hubs 42 each have a center through which the axis of rotation of the follower 4. In addition, such a hub 42 has a predetermined radius.

Une autre caractéristique consiste en ce que, lorsque les moyens de montage 9 comportent deux moyeux 42, ces moyeux 42 sont symétriques par rapport à un plan médian selon lequel s'étend le fouillot 4.Another characteristic is that, when the mounting means 9 comprise two hubs 42, these hubs 42 are symmetrical with respect to a median plane along which the follower 4 extends.

Les moyens de montage 9 comportent, également, au moins un logement 31 de forme oblongue. A ce propos, il convient d'observer que ce ou ces logements 31 sont délimités, chacun, d'une part, par deux côtés longitudinaux 310 parallèles et espacés d'une distance correspondant sensiblement au double du rayon du ou des moyeux 42 mais configurés pour autoriser un déplacement de ce ou ces moyeux 42 à l'intérieur de ce ou ces logements 31. D'autre part, ce ou ces logements 31 sont délimités, chacun, par deux portées hémisphériques (311 ; 311') dont le rayon est sensiblement égal au rayon du ou des moyeux 42.The mounting means 9 also comprise at least one housing 31 of oblong shape. In this regard, it should be noted that this or these housing 31 are delimited, each, on the one hand, by two longitudinal sides 310 parallel and spaced a distance corresponding substantially to twice the radius of the hub or hubs 42 but configured to allow a displacement of this or these hubs 42 inside this or these housings 31. On the other hand, this or these housing 31 are delimited, each, by two hemispherical bearings (311; 311 ') whose radius is substantially equal to the radius of the hub (s) 42.

En fait, ces deux portées hémisphériques (311 ; 311') présentent, chacune, un centre (312 ; 312') alors que les centres (312 ; 312') de ces deux portées hémisphériques (311 ; 311') sont distants d'un entraxe E correspondant au jeu longitudinal 10.In fact, these two hemispherical spans (311, 311 ') each have a center (312; 312') while the centers (312; 312 ') of these two hemispherical spans (311; 311') are distant from each other. a center distance E corresponding to the longitudinal clearance 10.

Les moyens de montage 9 permettent, en fait, un montage du fouillot 4 par rapport au boîtier 3 en sorte que ce fouillot 4 puisse adopter, d'une part, la position de déblocage en rotation illustrée figures 3 et 4 et, d'autre part, la positon de blocage en rotation illustrée figures 5 et 6. A ce propos, on observera que, dans la position de déblocage en rotation du fouillot 4, l'axe de rotation de ce fouillot 4 et/ou le centre du ou des moyeux 42 de ce fouillot 4 sont confondus avec le centre 312 de l'une 311 des deux portées hémisphériques (311 ; 311') du ou des logements 31 du boîtier 3. Dans la position de blocage en rotation du fouillot 4, l'axe de rotation de ce fouillot 4 et/ou le centre du ou des moyeux 42 de ce fouillot 4 sont confondus avec le centre 312' de l'autre 311' des deux portées hémisphériques (311 ; 311') du ou des logements 31 du boîtier 3.The mounting means 9 allow, in fact, a mounting of the follower 4 relative to the housing 3 so that the follower 4 can adopt, on the one hand, the unlocking position in rotation illustrated Figures 3 and 4 and, on the other hand, the blocking positon in illustrated rotation Figures 5 and 6 . In this respect, it will be observed that, in the unlocking position in rotation of the follower 4, the axis of rotation of this follower 4 and / or the center of the hub (s) 42 of this follower 4 coincide with the center 312 of the one of the two hemispherical bearings (311; 311 ') of the housing or recesses 31 of the housing 3. In the rotational locking position of the follower 4, the axis of rotation of this follower 4 and / or the center of the The hubs 42 of this follower 4 coincide with the center 312 'of the other 311' of the two hemispherical bearings (311; 311 ') of the housing 31 of the housing 3.

Tel que mentionné ci-dessus, la crémone 1 comporte des moyens de logement 7 pour loger le carré de transmission 5 à l'intérieur de l'ouverture 41 du fouillot 4, ceci avec un jeu transversal 8.As mentioned above, the espagnolette 1 comprises housing means 7 for housing the transmission square 5 inside the opening 41 of the follower 4, this with a transverse clearance 8.

A ce propos, on observera que, selon une autre caractéristique de l'invention, ce jeu transversal 8 est, alors, au moins égal au jeu longitudinal 10. Cette caractéristique permet, avantageusement, au fouillot 4 d'avoir un débattement, par rapport au carré de transmission 5, au moins un égal (voire supérieur) au débattement par rapport au boîtier 3. Ceci permet, alors, en position de verrouillage du fouillot 4, et en cas d'une contrainte C exercée sur la tringle 6 ou sur un organe de verrouillage (figures 5 et 6), au moyeu 42 (respectivement aux moyeux 42) de ce fouillot 4 de coopérer avec la portée hémisphérique 311' du logement 31 (respectivement des logements 31) du boîtier 3, ceci en sorte que ce fouillot 4 adopte une position de blocage en rotation.In this regard, it will be observed that, according to another characteristic of the invention, this transverse clearance 8 is then at least equal to the longitudinal clearance 10. This characteristic advantageously allows the follower 4 to have a clearance, relative to to the transmission square 5, at least one equal to (or greater than) the displacement relative to the housing 3. This allows, then, in the locking position of the follower 4, and in the case of a stress C exerted on the rod 6 or on a locking member ( Figures 5 and 6 ), the hub 42 (respectively the hubs 42) of the follower 4 to cooperate with the hemispherical bearing 311 'of the housing 31 (housing 31 respectively) of the housing 3, so that the follower 4 adopts a locking position in rotation .

Une autre caractéristique de l'invention consiste en ce que la crémone 1 comporte des moyens de positionnement (non représentés) pour au moins positionner le fouillot 4 par rapport au boîtier 3, ceci dans une position de déblocage du fouillot 4 autorisant la rotation de ce fouillot 4 par rapport au boîtier 3.Another feature of the invention consists in that the espagnolette 1 comprises positioning means (not shown) for at least positioning the follower 4 relative to the housing 3, this in a position of unlocking the follower 4 allowing the rotation of this follower 4 relative to the housing 3.

De tels moyens de positionnement peuvent, en fait, constituer des moyens de pré-positionnement pour positionner, lors de la fabrication de la crémone 1 et/ou préalablement à sa mise en place au sein du dispositif de fermeture, ledit fouillot 4 dans une position de déblocage dans laquelle ce fouillot 4 est susceptible de coopérer avec un carré de transmission 5 et/ou d'être actionné en rotation par un tel carré de transmission 5, ceci pour une commande en translation de la tringle 6.Such positioning means can, in fact, constitute pre-positioning means for positioning, during the manufacture of the espagnolette 1 and / or prior to its placing in the closure device, said follower 4 in an unlocking position in which this follower 4 is able to cooperate with a transmission square 5 and / or to be actuated in rotation by such a transmission square 5, this for a control in translation of the rod 6.

De tels moyens de positionnement peuvent, également, constituer des moyens de repositionnement pour repositionner le fouillot 4 dans une telle position de déblocage, ceci après que ce fouillot 4 ait été déplacé en translation et/ou positionné par rapport au boîtier 3, ceci dans une position de blocage en rotation de ce fouillot 4 par rapport au boîtier 3, plus particulièrement sous l'effet d'une contrainte C (notamment d'effraction).Such positioning means may also constitute repositioning means for repositioning the follower 4 in such a release position, after this follower 4 has been moved in translation and / or positioned relative to the housing 3, this in a rotational locking position of the follower 4 relative to the housing 3, more particularly under the effect of a stress C (including burglary).

En fait, de tels moyens de positionnement peuvent être constitués par des moyens de rappel élastique du fouillot 4 dans une telle position de déblocage.In fact, such positioning means may be constituted by elastic return means of the follower 4 in such a release position.

De tels moyens de rappel élastique peuvent adopter la forme d'au moins un ressort de rappel du fouillot 4 en position de déblocage.Such elastic return means may take the form of at least one return spring of the follower 4 in unlocking position.

Tel que mentionné ci-dessus, la tringle 6 est mobile en translation par rapport à ce boîtier 3, ceci entre une position de déverrouillage et une position de verrouillage. A ce propos, on observera que cette tringle 6 est, en fait, mobile selon une course déterminée et que, selon une autre caractéristique de l'invention, la longueur de cette course est supérieure au jeu transversal 8 et/ou au jeu longitudinal 10.As mentioned above, the rod 6 is movable in translation relative to the housing 3, this between an unlocking position and a locking position. In this regard, it will be observed that this rod 6 is, in fact, movable in a determined race and that, according to another characteristic of the invention, the length of this race is greater than the transverse clearance 8 and / or the longitudinal clearance 10 .

L'invention concerne, également, un système de verrouillage 2 pour un dispositif de fermeture d'une ouverture d'une construction. Tel que mentionné ci-dessus, ce système de verrouillage 2 comporte une crémone 1 et un carré de transmission 5.The invention also relates to a locking system 2 for a device for closing an opening of a construction. As mentioned above, this locking system 2 comprises a espagnolette 1 and a transmission square 5.

En fait, dans ce système de verrouillage 2, la crémone 1 présente les caractéristiques mentionnées ci-dessus.In fact, in this locking system 2, the espagnolette 1 has the characteristics mentioned above.

Quant au carré de transmission 5, celui-ci s'étend selon un axe (notamment un axe de rotation) et présente des côtés 50 présentant une longueur déterminée.As for the transmission square 5, it extends along an axis (including an axis of rotation) and has sides 50 having a predetermined length.

Tel que mentionné ci-dessus, la crémone 1 comporte des moyens de logement 7 pour loger le carré de transmission 5 à l'intérieur de l'ouverture 41 du fouillot 4, ceci avec un jeu transversal 8 selon une direction transversale par rapport à l'axe de rotation du fouillot 4.As mentioned above, the espagnolette 1 comprises housing means 7 for housing the transmission square 5 inside the opening 41 of the follower 4, this with a transverse clearance 8 in a direction transverse to the rotation axis of the follower 4.

A ce propos on observera que, selon une autre caractéristique de l'invention, les moyens de logement 7 sont, également, configurés pour loger ledit carré de transmission 5 à l'intérieur de l'ouverture 41 du fouillot 4, ceci avec le jeu transversal 8 selon une direction transversale par rapport à l'axe (notamment de rotation) de ce carré de transmission 5.In this respect it will be observed that, according to another characteristic of the invention, the housing means 7 are also configured to accommodate said transmission square 5 inside the opening 41 of the follower 4, this with the game. transverse 8 in a direction transverse to the axis (in particular of rotation) of this square of transmission 5.

Tel que mentionné ci-dessus, l'ouverture 41 du fouillot 4 présente une forme rectangulaire et comporte des petits côtés 410 ainsi que des grands côtés 411.As mentioned above, the opening 41 of the follower 4 has a rectangular shape and has short sides 410 and long sides 411.

En fait, une autre caractéristique du système de verrouillage 2 consiste en ce que, d'une part, les petits côtés 410 de l'ouverture 41 du fouillot 4 présentent une longueur sensiblement égale à celle des côtés 50 du carré de transmission 5 et, d'autre part, les grands côtés 411 de cette ouverture 41 du fouillot 4 présentent une longueur supérieure à celle de ces côtés 50 du carré de transmission 5. De plus, la différence de longueur entre les grands côtés 411 de l'ouverture 41 du fouillot 4 et les côtés 50 du carré de transmission 5 correspond au jeu transversal 8.In fact, another characteristic of the locking system 2 is that, on the one hand, the short sides 410 of the opening 41 of the follower 4 have a length substantially equal to that of the sides 50 of the transmission square 5 and, on the other hand, the long sides 411 of this opening 41 of the follower 4 have a length greater than that of these sides 50 of the transmission square 5. In addition, the difference in length between the long sides 411 of the opening 41 of the follower 4 and the sides 50 of the transmission square 5 corresponds to the transverse clearance 8.

Dans la suite de la description il sera décrit le fonctionnement de la crémone 1 et du système de verrouillage 2 conformes à l'invention.In the following description will be described the operation of the espagnolette 1 and the locking system 2 according to the invention.

Lorsque le fouillot 4 et la tringle 6 sont dans la position de verrouillage (figures 3 et 4), une contrainte C (notamment d'effraction) exercée sur la tringle 6 et/ou sur un organe de verrouillage provoque le déplacement en translation de cette tringle 6 (figure 5), ceci selon la direction de translation T, d'une part, à partir de la position de verrouillage de cette tringle 6 et dudit organe de verrouillage (figures 3 et 4) et, d'autre part, en direction d'une position de déverrouillage de cette tringle 6 et dudit organe de verrouillage (figures 1 et 2) .When the follower 4 and the rod 6 are in the locking position ( Figures 3 and 4 ), a stress C (in particular of breaking-in) exerted on the bead wire 6 and / or on a locking member causes the displacement in translation of this bead wire 6 ( figure 5 ), this in the direction of translation T, on the one hand, from the locking position of this rod 6 and said locking member ( Figures 3 and 4 ) and, on the other hand, towards an unlocking position of this rod 6 and said locking member ( Figures 1 and 2 ).

Sous l'effet du déplacement en translation de cette tringle 6, la crémaillère 60 de cette tringle 6 exerce, sur une dent de la denture 40 du fouillot 4, un effort correspondant à l'effort d'effraction exercé par la contrainte C sur la tringle 6 et/ou sur l'organe de verrouillage.Under the effect of the displacement in translation of this rod 6, the rack 60 of this rod 6 exerts, on a tooth of the toothing 40 of the follower 4, a force corresponding to the force of burglary exerted by the stress C on the rod 6 and / or on the locking member.

Cet effort est décentré par rapport à l'axe de rotation du fouillot 4 et génère, donc, automatiquement, sur ce fouillot 4, un moment correspondant au produit de l'effort et du bras de levier entre le point d'application de cet effort sur la dent de la denture 40 du fouillot 4 et l'axe de rotation de ce fouillot 4. Ce moment a tendance à faire tourner le fouillot 4 autour de son axe de rotation.This force is off-center with respect to the axis of rotation of the follower 4 and thus automatically generates, on this follower 4, a moment corresponding to the product of the force and the lever arm between the point of application of this effort. on the tooth of the toothing 40 of the follower 4 and the axis of rotation of the follower 4. This moment tends to rotate the follower 4 about its axis of rotation.

A ce propos, on observera que ce fouillot 4 est freiné en rotation par le carré de transmission 5, au travers de l'ouverture 41 qu'il comporte, ainsi que par des moyens annexes de commande associés à ce carré de transmission 5 (tels qu'une poignée de manoeuvre). Par ailleurs, ce carré de transmission 5 forme, avec les grands côtés 411 de l'ouverture 41 du fouillot 4, une liaison glissière conçue de manière à n'opposer qu'un frottement faible au mouvement de translation. On observera que ce faible frottement est obtenu par un choix de matériaux (notamment métalliques) présentant un faible coefficient de frottement, de faibles rugosités des états de surface et/ou d'un jeu transversal 8 faible.In this respect, it will be observed that this follower 4 is braked in rotation by the transmission square 5, through the opening 41 that it comprises, as well as by auxiliary control means associated with this transmission square 5 (such as only a maneuvering handle). Furthermore, this transmission square 5 forms, with the long sides 411 of the opening 41 of the follower 4, a slide connection designed to oppose only a low friction to the translational movement. It will be observed that this low friction is obtained by a choice of materials (especially metal) having a low coefficient of friction, low surface roughness and / or a low transverse clearance.

Etant donné que, en position de verrouillage du fouillot 4, le jeu transversal 8 et le jeu longitudinal 10 s'étendent selon une même direction, un déplacement en translation de ce fouillot 4 par rapport au boîtier 3 est autorisé de sorte que, sous l'effet de la coopération entre la crémaillère 60 de la tringle 6 et la denture 40 du fouillot 4, le déplacement en translation de la tringle 6 (lorsque la contrainte C est exercée sur cette tringle 6 et/ou sur l'organe de verrouillage) provoque le déplacement en translation du fouillot 4 par rapport au boîtier 3 ainsi que par rapport au carré de transmission 5. Ce déplacement en translation du fouillot 4 s'opère à partir de la position de déblocage en rotation de ce fouillot 4 (figures 3 et 4) sur une distance correspondant au moins au jeu longitudinal 10, voire au jeu transversal 8. Ce déplacement en translation s'opère, également, en direction de la position de blocage en rotation correspondant à une position de coopération dans laquelle le moyeu 42 (respectivement au moins un des moyeux 42) du fouillot 4 coopère avec une des portées hémisphériques 311' du logement 31 (respectivement d'au moins un des logements 31) du boîtier 3, ceci en un point de contact P (figures 5 et 6).Since, in the locking position of the follower 4, the transverse clearance 8 and the longitudinal clearance 10 extend in the same direction, a displacement in translation of the follower 4 relative to the housing 3 is allowed so that, under effect of the cooperation between the rack 60 of the rod 6 and the toothing 40 of the follower 4, the displacement in translation of the rod 6 (when the stress C is exerted on this rod 6 and / or on the locking member) causes displacement in translation of the follower 4 with respect to the housing 3 as well as with respect to the transmission square 5. translational movement of the follower 4 operates from the unlocking position in rotation of the follower 4 ( Figures 3 and 4 ) over a distance corresponding at least to the longitudinal clearance 10 or to the transverse clearance 8. This displacement in translation is also effected in the direction of the rotational locking position corresponding to a cooperation position in which the hub 42 (respectively at least one of the hubs 42) of the follower 4 cooperates with one of the hemispherical bearings 311 'of the housing 31 (or at least one of the housings 31) of the housing 3, this at a point of contact P ( Figures 5 and 6 ).

Dans cette position de coopération, le contact créé entre au moins un moyeu 42 du fouillot 4 et au moins une portée hémisphérique 311' du boîtier 3 génère, toujours sous l'action dudit effort susmentionné, un nouveau moment dont l'axe de rotation correspond sensiblement au point de contact P entre le moyeu 42 et la portée hémisphérique 311'. Ce moment a tendance à faire tourner le fouillot 4 autour de ce point de contact P de sorte que l'un des grands côtés 411 de l'ouverture du fouillot 41 est plaqué contre l'un des côtés 50 du carré de transmission 5. Etant donné que ce carré de transmission 5 est guidé en rotation par les moyens annexes de commande et/ou par des moyens associés au boîtier 3, ce carré de transmission 5 ne dispose que d'un unique degré de liberté, à savoir son propre axe de rotation. Il en découle que, dans ladite position de coopération, le nouveau moment engendre un état de blocage du fouillot 4 ainsi que de l'ensemble du mécanisme, ceci aussi longtemps que la contrainte C (notamment d'effraction) est maintenue.In this cooperation position, the contact created between at least one hub 42 of the follower 4 and at least one hemispherical surface 311 'of the housing 3 generates, again under the action of said force mentioned above, a new moment whose axis of rotation corresponds substantially at the point of contact P between the hub 42 and the hemispherical bearing 311 '. This moment has a tendency to turn the follower 4 around this point of contact P so that one of the long sides 411 of the opening of the follower 41 is pressed against one of the sides 50 of the transmission square 5. given that this transmission square 5 is guided in rotation by the auxiliary control means and / or by means associated with the housing 3, this transmission square 5 has only one degree of freedom, namely its own axis of rotation. It follows that, in said cooperation position, the new moment generates a locking state of the follower 4 as well as the entire mechanism, this as long as the stress C (including burglary) is maintained.

Ceci empêche, alors, la tringle 6 d'entraîner ce fouillot 4 en rotation, lorsque la contrainte C est exercée sur cette tringle 6 et/ou sur l'organe de verrouillage. Il en découle que le déplacement de cette tringle 6 en translation est empêché ce qui a pour effet d'empêcher, également, le déplacement de l'organe de verrouillage hors de sa position de verrouillage malgré l'application de la contrainte C. Il en découle que cet organe de verrouillage est maintenu dans sa position de verrouillage ce qui permet de garantir le verrouillage du système de verrouillage 2 et, par conséquent, le verrouillage du dispositif de fermeture.This prevents, then, the rod 6 to drive the follower 4 in rotation, when the stress C is exerted on the rod 6 and / or on the locking member. It follows that the displacement of this rod 6 in translation is prevented which also has the effect of preventing the displacement of the locking member out of its locking position despite the application of the constraint C. It It follows that this locking member is maintained in its position of locking which ensures the locking of the locking system 2 and, therefore, locking the closure device.

Après que la contrainte C ait cessé d'être exercée et à partir de la position de coopération (ou de la position de blocage en rotation du fouillot 4, figures 5 et 6), une action de commande de déverrouillage exercée par un utilisateur sur le carré de transmission 5 par l'intermédiaire d'un moyen de commande (tel qu'une poignée de manoeuvre) se traduit par l'application d'un moment centré sur l'axe de rotation du fouillot 4. Etant donné que le ou les moyeux 42 de ce fouillot 4 coopère (nt) avec la portée hémisphérique 311' du ou des logements 31 du boîtier 3, le fouillot 4 est autorisé à tourner librement. Il en découle que l'application dudit moment provoque la rotation de ce fouillot 4 et, ainsi, un contact entre au moins une dent de la denture 40 du fouillot 4 et le bord d'une ouverture 61 de la crémaillère 60 de la tringle 6, ceci en un point P' . Ainsi mis en contact de la tringle 6, le fouillot 4 prend appui sur la crémaillère 60 de cette tringle 6 pour, en poursuivant l'application du moment, provoquer la translation de ce fouillot 4 selon une direction parallèle à la direction de translation T de la tringle 6, ceci en sorte de permettre au fouillot 4 de quitter la position de blocage (figures 5 et 6) jusqu'à atteindre la position de déblocage (figures 3 et 4).After the stress C has ceased to be exerted and from the co-operating position (or the locking position in rotation of the follower 4, Figures 5 and 6 ), an unlocking control action exerted by a user on the transmission square 5 by means of a control means (such as an operating handle) results in the application of a moment centered on the 4. As the hub (s) 42 of this follower 4 cooperate (s) with the hemispherical bearing 311 'or the housing 31 of the housing 3, the follower 4 is allowed to rotate freely. It follows that the application of said moment causes the rotation of this follower 4 and, thus, a contact between at least one tooth of the toothing 40 of the follower 4 and the edge of an opening 61 of the rack 60 of the rod 6 , this at a point P '. Thus brought into contact with the bead wire 6, the follower 4 bears on the rack 60 of this bead wire 6 in order to continue the application of the moment, to cause the translation of this follower 4 in a direction parallel to the translation direction T of the rod 6, this so as to allow the follower 4 to leave the locking position ( Figures 5 and 6 ) until reaching the unlocking position ( Figures 3 and 4 ).

Dans cette position de déblocage du fouillot 4, l'axe (notamment de rotation) du carré de transmission 5 et l'axe (notamment de rotation) du fouillot 4 sont confondus, ce qui autorise une commande en rotation de ce fouillot 4 par le carré de transmission 5, ceci en vue d'un entraînement libre de la tringle 6. Aussi, dans la position de déblocage du fouillot 4, une action de commande de déverrouillage exercée sur le carré de transmission 5 provoque un passage du fouillot 4 de sa position de verrouillage (figures 3 et 4) vers sa position de déverrouillage (figures 1 et 2).In this unlocking position of the follower 4, the axis (in particular of rotation) of the transmission square 5 and the axis (in particular of rotation) of the follower 4 are combined, which allows a control in rotation of this follower 4 by the transmission square 5, this for a free drive of the rod 6. Also, in the unlocking position of the follower 4, an unlocking control action exerted on the transmission square 5 causes a passage of the follower 4 of its lock position ( Figures 3 and 4 ) to its unlock position ( Figures 1 and 2 ).
