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 lever for a locking system of a closing 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 construction and, more particularly, that of the manufacture of hardware intended to equip a device for closing 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.We already know such cremone bolts for a locking system of a closing 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 manœuvre 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 a cremone bolt comprises a box intended to be positioned inside a housing which comprises the closing device, more particularly the opening of such a closing device. This cremone bolt also comprises a nut, mounted at least in rotation inside the housing, this along an axis of rotation as well as between an unlocking position and a locking position. This follower has a toothing and an opening to receive a transmission square. Said cremone bolt further comprises a rod, movable in translation relative to the housing in a direction of translation, this between an unlocking position and a locking position. This rod comprises a rack engaged with the teeth of the follower, this for a translational drive 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 keeper, which comprises the locking system, and which equips, more particularly, the frame of the closing 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 has the effect of causing the rod to move out of its locked position and into its unlocked position. This results in an unlocking of the locking system which allows the opening of the closing 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 manœuvre disproportionnés à chaque manœuvre 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 œuvre des frottements importants de glissement sous charge entre les composants des moyens de verrouillage ce qui pénalise les manœuvres d'ouverture et de fermeture.In the particular case of closing devices designed to authorize a temporary retention of the opening in different preferred positions (open, closed, ajar or even tilt-and-turn, French-style, closed), it is customary to use additional elastic means linked to the locking means, this to perform the functions of temporary holding in these different positions. However, to avoid a user from exerting disproportionate maneuvering forces on each opening or closing maneuver, these elastic means have a limited holding capacity. It was, therefore, necessary to supplement these closing devices with burglar-proof means, which temporarily immobilize the locking means in positions adopted by these locking means when the opening adopts the preferred positions, and which oppose all movement or any opening attempt that would result from a stress exerted directly on these locking means in the context of a break-in. However, these burglar-proof means have numerous drawbacks. In particular, these anti-burglary means use many components so that they are particularly complex. These burglar-proof means can also implement significant sliding friction under load between the components of the locking means, which penalizes the opening and closing operations.

Le document EP 2 918 755 A1 divulgue une crémone pour un système de verrouillage d'un dispositif de fermeture d'une ouverture d'une construction. Cette crémone 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. Cette crémone comporte, aussi, 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. Ces moyens de montage comportent, d'une part, deux moyeux que comporte le fouillot latéralement et de part et d'autre, d'autre part, deux logements, que comporte de part et d'autre le boîtier, qui s'étendent chacun selon un axe parallèle à la direction de translation de la tringle, et à l'intérieur desquels s'étendent lesdits moyeux. Cette crémone 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. Dans ce document, l'un des moyeux présente une enveloppe dont le rayon n'est pas constant mais varie en direction de sa circonférence et présente une marche qui définit une surface de butée. Également, l'un des logements présente une surface interne qui s'écarte d'une trajectoire circulaire et comporte, d'une part, un support pour la réception d'un élément ressort et, d'autre part, une butée, que comporte le support, et qui est configurée pour coopérer avec la surface de butée de la marche.The document EP 2,918,755 A1 discloses a cremone bolt for a locking system of a device for closing an opening of a construction. This cremone bolt comprises housing means for accommodating the transmission square inside the opening of the follower, this with a transverse clearance in a transverse direction relative to the axis of rotation of the follower. This cremone bolt also includes mounting means for mounting the follower inside the housing, this with a longitudinal play in a direction parallel to the direction of translation of the rod. These mounting means comprise, on the one hand, two hubs which comprise the follower laterally and on both sides, on the other hand, two housings, which comprise on both sides the housing, which each extend along an axis parallel to the direction of translation of the rod, and inside which extend said hubs. This cremone bolt is configured so that, when the nut 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. In this document, one of the hubs has an envelope whose radius is not constant but varies in the direction of its circumference and has a step which defines a stop surface. Also, one of the housings has an internal surface which deviates from a circular path and comprises, on the one hand, a support for receiving a spring element and, on the other hand, a stop, which comprises the support, and which is configured to cooperate with the abutment surface of the step.

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 cremone bolt is characterized in that, on the one hand, it comprises housing means for accommodating the transmission square inside the opening of the follower, this with a transverse clearance in a transverse direction relative to 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 play in a direction parallel to the direction of translation of the rod and, on the other hand, it is configured so that, when the follower is in the locked 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 characteristic of the invention consists in that the housing means consist of the opening, which comprises the follower, which has a rectangular shape, and which comprises, on the one hand, short sides which have a length that is substantially equal to that of the sides of the transmission square and, on the other hand, of the long sides which have a length greater than that of the short sides of the opening

Les moyens de montage comportent, d'une part, deux moyeux, que comporte le fouillot latéralement et de part et d'autre, et qui adoptent chacun une forme circulaire et, d'autre part, deux logements, que comporte de part et d'autre le boîtier, qui adoptent chacun une forme oblongue, qui s'étendent chacun selon un axe parallèle à la direction de translation de la tringle, et à l'intérieur desquels s'étendent lesdits moyeux.The mounting means comprise, on the one hand, two hubs, which comprise the follower laterally and on both sides, and which each adopt a circular shape and, on the other hand, two housings, which comprise on the side and d 'other the housing, which each adopt an oblong shape, which each extend along an axis parallel to the direction of translation of the rod, and within which extend said hubs.

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

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 cremone bolt and a transmission square. This locking system is characterized by the fact that the cremone bolt 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 cremone bolt, the transmission square is housed inside the opening of the follower with transverse play while this follower is housed inside the housing with longitudinal play. In the locking position of the follower, the transverse clearance and the longitudinal clearance extend in the same direction, which allows translation of the follower relative to the housing. Also, in the context of a break-in, a break-in stress, exerted directly on the rod or on a locking member associated with this rod, has the effect of causing such translation, relative to the housing, of the follower which adopts , then, a rotation locking position. Such locking 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 a burglary constraint, in a locking position which guarantees the locking of the locking system and, therefore, of the closing 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 particular technical characteristics of the cremone bolt according to the present invention. In fact, these particular technical characteristics relate to specific arrangements (transverse play and longitudinal play) and clever that present traditional elements (the follower and the case) that a cremone bolt comprises. Also and advantageously, the cremone bolt according to the invention incorporates elements traditional but which, however, have such amenities.

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 cremone bolt according to the invention incorporates a limited number of parts (in particular the same number of parts as a traditional cremone bolt devoid of specific anti-tampering means) and therefore constitutes a significant simplification compared to the cremone bolts. anti-burglary 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 bolt according to the invention, by its particular technical characteristics, does not cause sliding friction under load which could penalize the manipulation 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 given that the cremone bolt according to the invention incorporates traditional elements (although having fitted out), this cremone bolt is capable of easily and cheaply replacing conventional cremone bolts, or even of replacing such cremone bolts, in particular 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 building sector and, more particularly, that of the manufacture of hardware intended to equip a device for closing 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 therefore relates more particularly to a cremone bolt 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 a cremone bolt 1 comprises a box 3 intended to be positioned inside a housing which comprises said closing device, more particularly the opening of such a closing 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 bolt 1 also comprises a nut 4, mounted at least in rotation inside the housing 3, this along an axis of rotation as well as 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 share, an opening 41, in particular through, configured to receive a transmission square 5 that includes the locking system 2.

La crémone 1 comporte, également, une tringle 6 qui peut être constituée par une tringle de manœuvre 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 manœuvre.The cremone bolt 1 also comprises a rod 6 which may be constituted by an operating rod comprising at least one locking member (not shown) designed to cooperate with at least one keeper (not shown), which comprises the locking system 2 , and which equips, more particularly, the frame of the closing device. Alternatively, this rod 6 can 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, more 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 direction of translation 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 teeth 40 of the follower 4. In fact, this rack 60 comprises at least one recess (or even a plurality of recesses) or (and preferably) at least one opening 61 (or even a plurality openings as visible in the appended figures) which cooperate with the tooth or teeth of the toothing 40 of the follower 4 this in order, under the impulse of a rotation of this follower 4, to drive the rod 6 in translation in the direction of 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 cremone bolt 1 comprises housing means 7 for accommodating the transmission square 5 inside the opening 41 of the follower 4, this with a transverse clearance 8 in a transverse direction relative 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 bolt 1 comprises mounting means 9 for mounting the nut 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 bolt 1 is then configured so that when the nut 4 is in the locking position ( figures 3 to 6 ), the transverse play 8 and the longitudinal play 10 extend in the same direction (namely a direction parallel to the direction of translation T of the rod 6), this to allow a displacement in translation of the follower 4 relative to the housing 3, between an unlocking position in rotation ( figures 3 and 4 ) and a rotation locking position ( 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 regard, it will be observed that, when the follower 4 and the rod 6 are in the locking position, a stress C (in particular of burglary) exerted on the rod 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 in the direction of 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 of the follower 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 position of unlocking in rotation of this follower 4 ( figures 3 and 4 ) and for positioning this follower 4 in a position for blocking the rotation of this follower 4 relative to the housing 3 ( Figures 5 and 6 ). In this position of blocking rotation of the follower 4, the blocking of rotation of this follower 4 prevents the rod 6 from driving this follower 4 in rotation which prevents the displacement of this 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 guarantees the locking of the locking 2 and, consequently, locking the closing 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 cremone bolt 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 transverse direction relative to the axis of rotation 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 manœuvre 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 includes the follower 4, and which has a rectangular shape. In fact, it will be observed that this opening 41 then comprises, 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 operating square 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 play 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 cremone bolt 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 direction of translation T of the rod 6.

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.These mounting means 9 in fact comprise on the one hand, two hubs 42, which comprise the follower 4 laterally and on either side, and which each adopt a circular shape and, on the other hand, two housings 31, which comprise on both sides the housing 3, which each take an oblong shape, which each extend along an axis parallel to the direction of translation T of the rod 6, and inside which said hubs 42 extend.

Il convient d'observer que 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.It should be observed that these hubs 42 each have a center crossed by the axis of rotation of the follower 4. In addition, such a hub 42 has a determined radius.

Une autre caractéristique consiste en ce que ces moyeux 42 sont symétriques par rapport à un plan médian selon lequel s'étend le fouillot 4.Another characteristic is that these hubs 42 are symmetrical with respect to a median plane along which the follower 4 extends.

Il convient d'observer que 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 des moyeux 42 mais configurés pour autoriser un déplacement de ces moyeux 42 à l'intérieur de ces logements 31. D'autre part, 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.It should be observed that these housings 31 are delimited, each, on the one hand, by two longitudinal sides 310 parallel and spaced by a distance corresponding substantially to twice the radius of the hubs 42 but configured to allow a displacement of these hubs 42 inside these housings 31. On the other hand, these housings 31 are each delimited by two hemispherical bearing surfaces (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 bearings (311; 311 ') each have a center (312; 312') while the centers (312; 312 ') of these two hemispherical bearings (311; 311') are distant from 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 des moyeux 42 de ce fouillot 4 sont confondus avec le centre 312 de l'une 311 des deux portées hémisphériques (311 ; 311') 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 des moyeux 42 de ce fouillot 4 sont confondus avec le centre 312' de l'autre 311' des deux portées hémisphériques (311 ; 311') des logements 31 du boîtier 3.The mounting means 9 allow, in fact, mounting the follower 4 relative to the housing 3 so that this follower 4 can adopt, on the one hand, the unlocked position in rotation illustrated figures 3 and 4 and, on the other hand, the blocking position in rotation illustrated Figures 5 and 6 . In this regard, 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 hubs 42 of this follower 4 are coincident with the center 312 of one 311 of the two hemispherical bearing surfaces (311; 311 ') of the housings 31 of the housing 3. In the position of rotation lock of the follower 4, the axis of rotation of this follower 4 and / or the center of the hubs 42 of this follower 4 are merged with the center 312 'of the other 311' of the two hemispherical bearings (311; 311 ') of the housings 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 cremone bolt 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), aux moyeux 42 de ce fouillot 4 de coopérer avec la portée hémisphérique 311' 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 at the transmission square 5, at least one equal (or even greater) to the travel relative to the housing 3. This then makes it possible, in the locking position of the follower 4, and in the event of a stress C exerted on the rod 6 or on a locking member ( Figures 5 and 6 ), to the hubs 42 of this follower 4 to cooperate with the hemispherical bearing surface 311 ′ of the housings 31 of the housing 3, this so that this follower 4 adopts a position of locking 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 characteristic of the invention consists in that the cremone bolt 1 comprises positioning means (not shown) for at least positioning the follower 4 relative to the housing 3, this in a position for unlocking the follower 4 allowing the rotation of this follower 4 relative to 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 production of the cremone bolt 1 and / or prior to its put into place within the closing device, said follower 4 in an unlocking position in which this follower 4 is capable of cooperating with a transmission square 5 and / or of being actuated in rotation by such a transmission square 5, this for a command 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 can also constitute repositioning means for repositioning the follower 4 in such an unlocking position, this after this follower 4 has been moved in translation and / or positioned relative to the housing 3, this in a position for blocking in rotation of this follower 4 relative to the housing 3, more particularly under the effect of a constraint C (in particular of 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 can be constituted by elastic return means of the follower 4 in such an unlocking 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 can take the form of at least one return spring of the follower 4 in the unlocked 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 this 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, mobile according to a determined stroke and that, according to another characteristic of the invention, the length of this stroke 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 cremone bolt 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 cremone bolt 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, this extends along an axis (in particular an axis of rotation) and has sides 50 having a determined 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 cremone bolt 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 transverse direction relative to the axis of rotation 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 regard, 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 play transverse 8 in a transverse direction relative to the axis (in particular of rotation) of this transmission square 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 as well as 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 consists in 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, the operation of the cremone bolt 1 and of the locking system 2 according to the invention will be described.

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 burglary) exerted on the rod 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, on the one hand, from the locking position of this rod 6 and of 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 breaking force 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 effort is off-center with respect to the axis of rotation of the follower 4 and therefore generates, automatically, on this follower 4, a moment corresponding to the product of the effort 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 this follower 4. This moment tends to rotate the follower 4 around 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 manœuvre). 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 regard, it will be observed that this follower 4 is braked in rotation by the transmission square 5, through the opening 41 which it comprises, as well as by additional control means associated with this transmission square 5 (such than a handle). Furthermore, this transmission square 5 forms, with the long sides 411 of the opening 41 of the follower 4, a slide connection designed so as 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 (in particular metallic) having a low coefficient of friction, low roughness of the surface conditions and / or a low transverse clearance 8.

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 au moins un des moyeux 42 du fouillot 4 coopère avec une des portées hémisphériques 311' 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 this follower 4 relative to the housing 3 is authorized so that, under the effect of 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 relative to the housing 3 as well as relative to the transmission square 5. This translational displacement of the follower 4 operates from the unlocking position in rotation of this follower 4 ( figures 3 and 4 ) over a distance corresponding at least to the longitudinal clearance 10, or even to the transverse clearance 8. This displacement in translation also takes place in the direction of the rotation locking position corresponding to a cooperation position in which at least one of the hubs 42 of the follower 4 cooperates with one of the hemispherical bearing surfaces 311 ′ of at least one of the housings 31 of the housing 3, this at a contact point 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 position of cooperation, the contact created between at least one hub 42 of the follower 4 and at least one hemispherical bearing surface 311 'of the housing 3 generates, still 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 surface 311 '. This moment tends to rotate the follower 4 around this point of contact P so that one of the long sides 411 of the opening of follower 41 is pressed against one of the sides 50 of the transmission square 5. Being 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 a single degree of freedom, namely its own axis of rotation. It follows that, in said position of cooperation, the new moment generates a locking state of the follower 4 as well as of the entire mechanism, this as long as the stress C (in particular of 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 then prevents the rod 6 from driving this follower 4 in rotation, when the stress C is exerted on this rod 6 and / or on the locking member. It follows that the displacement of this rod 6 in translation is prevented which has the effect of preventing, also, the displacement of the locking member out of its locking position despite the application of the stress C. It follows that this locking member is held in its position of locking which makes it possible to guarantee the locking of the locking system 2 and, consequently, the locking of the closing 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 manœuvre) se traduit par l'application d'un moment centré sur l'axe de rotation du fouillot 4. Etant donné que les moyeux 42 de ce fouillot 4 coopèrent avec la portée hémisphérique 311' 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 constraint C has ceased to be exerted and from the cooperation position (or the rotation locking position 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 'axis of rotation of the follower 4. Since the hubs 42 of this follower 4 cooperate with the hemispherical bearing surface 311' of the housings 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 rod 6, the follower 4 bears on the rack 60 of this rod 6 for, by continuing the application of the moment, causing 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 release 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 position for unlocking 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 authorizes a rotation control 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 passage of the follower 4 from its locking position ( figures 3 and 4 ) to its unlocking position ( Figures 1 and 2 ).
