Description

La présente invention concerne une ferrure de type crémone ou crémone-serrure, conçue apte à être encastrée dans une rainure en feuillure de menuiserie et comportant au moins un fouillot pour l'entraînement d'au moins une tringle de manoeuvre, le dit fouillot étant monté en rotation dans un boîtier autour d'un axe de rotation décalé par rapport au plan de ladite tringle de manoeuvre, du côté opposé à la rainure d'encastrement.The present invention relates to a cremone-type or espagnolette-lock type fitting, designed adapted to be embedded in a groove groove carpentry and having at least one follower for driving at least one operating rod, the said follower being mounted in rotation in a housing around an axis of rotation offset from the plane of said operating rod, on the opposite side to the embedding groove.

La présente invention entre dans le domaine de la quincaillerie du bâtiment et concerne plus particulièrement le domaine des ferrures de verrouillage, du type crémone ou crémone-serrure.The present invention is in the field of building hardware and more particularly relates to the field of lock fittings, type cremone or espagnolette-lock.

Une telle ferrure de verrouillage comporte, de façon connue, un mécanisme de commande logé dans un boîtier comportant au moins un fouillot pourvu d'une denture ou analogue, sur laquelle vient s'engrener au moins une crémaillère associée, directement ou au travers d'un chevalet, à une tringle de manoeuvre. Ce fouillot comporte en son centre un moyeu dont les extrémités, de part et d'autre de ce fouillot, sont maintenues en rotation dans des ouvertures et/ou des logements prévus à cet effet au niveau de parois verticales avant et arrière dudit boîtier.Such locking fitting comprises, in known manner, a control mechanism housed in a housing comprising at least one follower provided with a toothing or the like, on which is engaged at least one associated rack, directly or through an easel, to a rod of maneuvering. This nut has at its center a hub whose ends, on either side of the follower, are rotated in openings and / or housings provided for this purpose at vertical walls front and rear of said housing.

L'usager est en mesure d'agir, au travers d'un mécanisme de commande, par un bouton, une poignée, ou analogue, commandant directement ou non la rotation du fouillot, sur une tringle de manoeuvre s'étendant au-dessus et/ou en-dessous dudit boîtier. A noter que ces modes de liaison fouillot-tringle de manoeuvre se retrouvent tant au niveau des crémones de type mono que bidirectionnelles, c'est à dire aptes à communiquer à deux tringles des déplacements dans des directions opposées.The user is able to act, through a control mechanism, by a button, a handle, or the like, directly or indirectly controlling the rotation of the follower, on an operating rod extending above and / or below said housing. It should be noted that these modes of connection fouillot-rod maneuver are found both in the cremone type mono or bidirectional, ie able to communicate two rods displacements in opposite directions.

Quoi qu'il en soit, de telles crémones sont habituellement implantées dans une rainure prévue à cet effet en feuillure d'un ouvrant de porte, fenêtre ou analogue.Anyway, such cremones are usually implanted in a groove provided for this purpose in rebate of a door leaf, window or the like.

Par ailleurs, au droit de l'ouverture dans le fouillot le montant ou éventuellement la traverse de cet ouvrant, accueillant le boîtier de cette crémone, comporte une ouverture autorisant le passage de ce carré de manoeuvre.Moreover, the right of the opening in the follower amount or possibly the cross of this opening, welcoming the housing of this cremone, has an opening allowing the passage of this square maneuver.

Toutefois, l'ampleur de la rainure pratiquée dans une menuiserie, pour accueillir l'ensemble du mécanisme d'une telle ferrure, se traduit souvent par un affaiblissement local de cette menuiserie, alors qu'on recherche au contraire, lors de la pose d'une telle ferrure, un renforcement de la sécurité.However, the extent of the groove practiced in a carpentry, to accommodate the entire mechanism of such a fitting, often results in a local weakening of this joinery, while one seeks instead, during the installation of such a fitting, a reinforcement of security.

Cet affaiblissement est particulièrement préjudiciable dans le cas d'utilisation de menuiseries en profils creux, par exemple en matière plastique, notamment en PVC.This weakening is particularly detrimental in the case of using hollow joinery, for example plastic, especially PVC.

La rainure pratiquée par avance dans la menuiserie peut, encore, se révéler de dimension insuffisante, selon le type de ferrure utilisée, ce qui se traduit par des retouches coûteuses souvent exécutées sur site.The groove made in advance in the carpentry may, again, be of insufficient size, depending on the type of fitting used, which results in expensive retouching often performed on site.

On connaît des tentatives pour pallier ce problème, et permettre une fabrication plus facile et plus économique, avec le moins de retouches possible sur la menuiserie.There are known attempts to overcome this problem, and allow easier and more economical manufacturing, with the least possible retouching on the joinery.

Ainsi le document DE 203 08 230 U1 décrit un mécanisme de ferrure à crémone montée dans une rainure en feuillure de menuiserie, avec une crémone et un fouillot. Ce dernier est couplé avec un levier de manoeuvre par un arbre, par exemple un doigt polygonal, et coopère avec des évidements de la crémone. L'arbre de liaison entre le levier de manoeuvre et le fouillot, ici coaxiaux, est situé, par rapport au fond de la rainure, au-dessus de la crémone , et au-delà du plan du plan de feuillure.So the document DE 203 08 230 U1 discloses a cremone fitting mechanism mounted in a carpentry groove groove, with a cremone and a follower. The latter is coupled with an operating lever by a shaft, for example a polygonal finger, and cooperates with recesses of the espagnolette. The connecting shaft between the operating lever and the follower, here coaxial, is located, with respect to the bottom of the groove, above the cremone, and beyond the plane of the rabbet plane.

Ce fouillot traverse une ouverture longitudinale ménagée au niveau d'une têtière installée en retrait et en affleurement du plan de feuillure. Il est guidé par des paliers dans un boîtier, qui est fixé saillant par rapport à la têtière.This follower passes through a longitudinal opening formed at a headrest installed recessed and flush with the rabbet plane. It is guided by bearings in a housing, which is fixed protruding from the headrest.

Un tel boîtier occupe un volume important, qui n'est pas toujours compatible avec un montage sur une menuiserie telle qu'une fenêtre à deux battants sans montant central, où ce boîtier doit se loger dans l'espace compris entre les deux battants dans leur position de fermeture, ce qui peut alors nécessiter des retouches, notamment au niveau du battant antagoniste.Such a housing occupies a large volume, which is not always compatible with mounting on a joinery such as a window with two leaves without central pillar, where this housing must be housed in the space between the two leaves in their closing position, which may then require retouching, especially at the level of the antagonistic wing.

La demande de brevet EP 1 462 594 A1 décrit de façon analogue un mécanisme de ferrure pour porte, fenêtre ou analogue, notamment une crémone à larder dans une rainure en feuillure de menuiserie, comportant un boîtier, une tringle de crémone, et un fouillot dont la denture coopère avec celle de la tringle de crémone, et dont l'axe de rotation est déporté d'une certaine distance par rapport à la tringle de crémone, du côté opposé à celle-ci par rapport au plan de feuillure. Ce fouillot est guidé par des paliers dans le boîtier monté saillant par rapport au plan de feuillure. Son débattement angulaire est inférieur à 180°, et proche de 90°. L'agencement du boîtier et du fouillot est tel que ce dernier est limité en butée de part et d'autre de sa course angulaire.The patent application EP 1 462 594 A1 similarly describes a fitting mechanism for a door, window or the like, in particular a mortise cremone in a carpentry groove groove, comprising a housing, a cremone rod, and a follower whose toothing cooperates with that of the rod of cremone, and whose axis of rotation is offset from a distance from the espagnolette rod, the opposite side thereof relative to the rabbet plane. This follower is guided by bearings in the housing mounted projecting relative to the rabbet plane. Its angular deflection is less than 180 °, and close to 90 °. The arrangement of the housing and the follower is such that the latter is limited in abutment on both sides of its angular stroke.

Si ce débattement angulaire, proche de 90°, est bien adapté à certains types d'ouvertures, notamment une ouverture à la française, il ne permet pas l'adaptation à des portes ou fenêtres de type oscillant-battant. En effet pour permettre une ouverture à la fois en abattant et à la française, il est souvent utile, pour distinguer l'une de l'autre, de pouvoir communiquer à la poignée ou au bouton de commande une rotation d'amplitude suffisante, de l'ordre de 180°, se traduisant habituellement par un encombrement important du mécanisme de verrouillage, qui dans le cas d'un fouillot déporté, extérieurement par rapport au plan des tringles de manoeuvre, du côté opposé à la rainure d'encastrement, peut s'avérer incompatible avec le jeu en feuillure du profil de la menuiserie.Although this angular deflection, close to 90 °, is well adapted to certain types of openings, in particular a French opening, it does not allow adaptation to doors or windows of oscillating-swinging type. Indeed to allow an opening at the same time by flipping and the French, it is often useful, to distinguish one from the other, to be able to communicate to the handle or the knob a rotation of sufficient amplitude, the order of 180 °, usually resulting in a large locking, which in the case of a remote follower, externally relative to the plane of the operating rods, the opposite side to the embedding groove, may be incompatible with the rebate clearance of the profile of the joinery.

La présente invention se propose de pallier ce problème en proposant une ferrure de faible encombrement, dans laquelle le débattement du fouillot peut atteindre 180°.The present invention proposes to overcome this problem by providing a small footprint fitting, in which the travel of the follower can reach 180 °.

Ainsi, l'invention concerne une ferrure de type crémone ou crémone-serrure, conçue apte à être encastrée dans une rainure en feuillure de menuiserie et comportant au moins un fouillot pour l'entraînement d'au moins une tringle de manoeuvre, le dit fouillot étant monté en rotation dans un boîtier autour d'un axe de rotation décalé par rapport au plan de ladite tringle de manoeuvre, du côté opposé à la rainure d'encastrement, caractérisée par le fait que le fouillot comprend au moins un premier et un second secteurs dentés et comporte des moyens d'entraînement conçus aptes à entraîner, au-delà d'une première course angulaire au moins partiellement à vide pour l'entraînement du premier secteur denté, le second secteur denté sur une course angulaire correspondant à une course angulaire à vide, au moins partiellement, dudit fouillot par rapport au premier secteur denté.Thus, the invention relates to a type of espagnolette or espagnolette-lock, designed adapted to be embedded in a rabbet groove carpentry and having at least one follower for driving at least one operating rod, the said follower being mounted in rotation in a housing about an axis of rotation offset from the plane of said operating rod, on the opposite side to the embedding groove, characterized in that the follower comprises at least a first and a second toothed sectors and comprises drive means designed capable of driving, beyond a first angular stroke at least partially empty for the drive of the first sector toothed, the second sector gear on an angular stroke corresponding to an angular stroke at least partially empty of said follower relative to the first toothed sector.

Selon une autre particularité de l'invention, le premier secteur denté est conçu apte à coopérer avec une première portion de crémaillère et le deuxième secteur denté est conçu apte à coopérer avec une seconde portion de crémaillère, celle-ci étant conçue apte à assurer le prolongement du mouvement susceptible d'être communiqué par la première portion de crémaillère (associée à un chevalet ou une tringle de manoeuvre).According to another feature of the invention, the first toothed sector is designed to cooperate with a first rack portion and the second toothed sector is designed adapted to cooperate with a second rack portion, the latter being designed to ensure the extension of the movement likely to be communicated by the first rack portion (associated with an easel or rod maneuver).

De manière avantageuse encore, les secteurs dentés sont décalés l'un par rapport à l'autre par rapport à l'axe du fouillot, tandis que les portions de crémaillère sont décalées en correspondance sur le chevalet ou la tringle de manoeuvre.Advantageously, the toothed sectors are offset relative to each other with respect to the axis of the follower, while the rack portions are offset in correspondence on the easel or the operating rod.

De manière avantageuse encore, chaque portion de crémaillère est prolongée, au moins à l'une de ses extrémités, par un dégagement autorisant une course à vide par rapport au secteur denté correspondant.Advantageously, each rack portion is extended, at least at one of its ends, by a clearance allowing a vacuum stroke relative to the corresponding tooth sector.

Les avantages qui découlent de la première invention consistent en ce que, tout en disposant d'un fouillot décalé extérieurement par rapport à la rainure d'encastrement de la ferrure, il est possible de transmettre à ce fouillot une rotation d'un angle supérieur à 90° voire 180°, si ce n'est pas davantage, selon la taille des secteurs dentés, tout en limitant l'emprise de ce fouillot sur un secteur de 180°. Autrement dit, malgré ce décalage extérieurement au plan de feuillure du fouillot, il peut être associé pour ce type de crémone ou crémone-serrure à des menuiseries à ouvertures multiples, notamment de type oscillo-battant.The advantages which derive from the first invention consist in that, while having a nut offset externally with respect to the fitting groove of the fitting, it is possible to transmit to this follower a rotation of an angle greater than 90 ° or 180 °, if not more, depending on the size of the toothed sectors, while limiting the grip of this nut on a sector of 180 °. In other words, despite this offset externally to the furrow rebate plane, it can be associated for this type of espagnolette or espagnolette-lock to joinery with multiple openings, including tilt-and-turn type.

Tel que représenté dans les figures des dessins ci-joints, la présente invention a trait au domaine des ferrures de type crémone ou crémone-serrure pour porte, fenêtre ou similaire.As shown in the figures of the accompanying drawings, the present invention relates to the field of hardware type cremone or espagnolette-lock for door, window or the like.

Particulièrement, ladite ferrure 1 est prévue apte à être encastrée dans une rainure 2 prévue en feuillure 3 de cette menuiserie. Habituellement la ferrure équipe un ouvrant.In particular, said fitting 1 is provided capable of being embedded in a groove 2 provided in rebate 3 of this joinery. Usually the hardware equips an opening.

Tout particulièrement, elle comporte un boîtier 4 servant de logement au mécanisme d'entraînement sur lequel l'usager est susceptible d'intervenir selon le cas au moyen d'une poignée ou d'un bouton de commande voire d'un élément à clé. Au dessus et/ou en dessous du boîtier 4 s'étend une tringle de manoeuvre 5, destinée à assurer une fonction de verrouillage/déverrouillage. Cette ou ces tringles de manoeuvre 5 se déplacent, usuellement, à l'arrière d'une têtière 7 refermant la rainure d'encastrement 2 en feuillure 3.In particular, it comprises a housing 4 serving as a housing for the drive mechanism on which the user is likely to intervene as appropriate by means of a handle or a control button or a key element. Above and / or below the housing 4 extends an operating rod 5, intended to provide a locking / unlocking function. This or these operating rods 5 move, usually, to the rear of a headrest 7 closing the recess groove 2 rabbet 3.

De manière particulière, cette ferrure 1 comporte un fouillot 8 qui, dans le cas présent est monté en rotation dans le boîtier 4 autour d'un axe de rotation 9 qui est décalé par rapport au plan 10 de la ou des tringles de manoeuvre 5, du côté opposé à la rainure d'encastrement 2.In particular, this fitting 1 comprises a follower 8 which, in this case, is rotatably mounted in the casing 4 about an axis of rotation 9 which is offset relative to the plane 10 of the operating rod or rods 5, on the opposite side to the embedding groove 2.

D'ores et déjà on précisera que la présente ferrure de type crémone ou crémone-serrure peut être équipée d'une seule tringle de manoeuvre mono-directionnelle venant s'étendre au dessus et/ou en dessous du boîtier 4 tout comme elle peut être pourvue de deux tringles 5 distinctes, susceptibles de se déplacer en opposition au travers d'un pignon inverseur.From now on we will specify that the present type fitting espagnolette or espagnolette-lock can be equipped with a single directional rod mono-directional extending above and / or below the housing 4 as it can be provided with two separate rods 5, likely to move in opposition through a reversing gear.

De manière particulière à l'invention, le fouillot comporte un premier secteur denté 11 et un second secteur denté 12 qui, dans le mode de réalisation illustré dans les figures des dessins ci-joints, sont coaxiaux à l'axe 9 de ce fouillot 8.In a particular way to the invention, the follower comprises a first toothed sector 11 and a second toothed sector 12 which, in the embodiment illustrated in the figures of the accompanying drawings, are coaxial with the axis 9 of this follower 8 .

Tout particulièrement celui-ci comporte un moyeu 13 maintenu en rotation dans le boîtier 4, ce moyeu 13 comportant une ouverture 14 pour la réception de ce qui est communément appelé un carré de manoeuvre sur lequel est susceptible d'agir l'usager par l'intermédiaire d'une poignée ou d'un bouton de commande. On notera, en particulier, que ce carré de manoeuvre peut adopter une section qui n'est pas nécessairement carrée, comme cela est illustré dans les figures. L'ouverture 14 de ce moyeu 13 vient encore coïncider avec des ouvertures correspondantes 15 et 16, dans des parois latérales avant et arrière 4A, 4B du boîtier 4.This particularly includes a hub 13 rotated in the housing 4, the hub 13 having an opening 14 for receiving what is commonly called a maneuvering square on which the user is likely to act by the intermediate handle or control knob. It will be noted, in particular, that this square maneuver can adopt a section that is not necessarily square, as is illustrated in the figures. The opening 14 of this hub 13 again coincides with corresponding openings 15 and 16, in the front and rear side walls 4A, 4B of the housing 4.

Tout particulièrement, le fouillot 8 comporte des moyens d'entraînement 17 conçus aptes à entraîner, au delà d'une première course angulaire à vide 18 pour l'entraînement du premier secteur denté 11, le second secteur denté 12 sur une course angulaire 19 correspondant, au moins en partie, à une course angulaire à vide dudit fouillot 8 et plus exactement de son moyeu 13, par rapport audit premier secteur denté 11.In particular, the follower 8 comprises drive means 17 designed capable of driving, beyond a first angular vacuum stroke 18 for driving the first toothed sector 11, the second sector gear 12 on a corresponding angular stroke 19 at least in part, at an empty angular stroke of said follower 8 and more precisely of its hub 13, with respect to said first toothed sector 11.

Plus particulièrement, lesdits moyens d'entraînement 17 sont constitués, essentiellement, par un moyeu 13 du fouillot 8, constitué par deux demi-moyeux 13A, 13B, associés, respectivement, au premier 11 et au second secteur denté 12. chaque demi-moyeu comporte deux doigts d'entraînement 20, 21 qui se distinguent par leur longueur radiale, le premier étant plus long que le second. Ces doigts d'entraînement 20, 21, sont conçus aptes à coopérer avec un pion d'entraînement 22A, 22B, que comporte chaque secteur denté 11, 12, sachant que ce pion d'entraînement 22A, 22B, est monté mobile en translation dans une lumière 23A, 23B, s'étendant au moins radialement au niveau d'un secteur denté 11, 12.More particularly, said drive means 17 are constituted, essentially, by a hub 13 of the follower 8, constituted by two half-hubs 13A, 13B, associated, respectively, with the first 11 and the second toothed sector 12. each half-hub comprises two driving fingers 20, 21 which are distinguished by their radial length, the first being more long than the second. These drive fingers 20, 21 are designed to cooperate with a drive pin 22A, 22B, which comprises each toothed sector 11, 12, knowing that this drive pin 22A, 22B is mounted to move in translation in a light 23A, 23B, extending at least radially at a toothed sector 11, 12.

Plus exactement, la mobilité à composante radiale du pion d'entraînement 22A, 22B, dans la lumière 23A, 23B, d'un secteur denté 11, 12, est définie de sorte que, dans une première position 24 où ce pion d'entraînement 22A, 22B se situe au plus près de l'axe de rotation 9, chacun des doigts d'entraînement 20, 21, est conçu apte à agir sur ce pion pour l'entraînement en rotation du secteur denté 11, 12, correspondant, tandis que dans une seconde position 25 où ce pion 22A, 22B est le plus éloigné dudit axe de rotation 9, seul le doigt d'entraînement le plus long 20, permet la commande en rotation du secteur denté en question au travers de ce pion 22A, 22B.More exactly, the radial component mobility of the drive pin 22A, 22B, in the slot 23A, 23B, of a toothed sector 11, 12, is defined so that in a first position 24 where this driving pin 22A, 22B is located as close to the axis of rotation 9, each of the driving fingers 20, 21, is designed capable of acting on this pin for the rotary drive of the toothed sector 11, 12, corresponding, while that in a second position 25 where this pin 22A, 22B is furthest from said axis of rotation 9, only the longest drive finger 20, allows the rotation control of the toothed sector in question through the pin 22A, 22B.

Conformément à ce mode de réalisation de l'invention, le boîtier 4 comporte, de son côté, des moyens de commande en translation radiale 26 du pion d'entraînement 22A, 22B, entre ces positions extrêmes 24 et 25. Selon l'invention, ces moyens de commande en translation radiale 26 sont définis par des pistes de cames 27A, 27B, définies du côté interne à des parois latérales 4A, 4B du boîtier 4.According to this embodiment of the invention, the casing 4 comprises, on its side, radial translation control means 26 of the driving pin 22A, 22B, between these extreme positions 24 and 25. According to the invention, these radial translation control means 26 are defined by cam tracks 27A, 27B, defined on the internal side to side walls 4A, 4B of the casing 4.

Selon un mode d'exécution avantageux, ces pistes de cames 27A, 27B, se présentent sous forme de rainures du côté interne de ces parois latérales 4A, 4B, rainures dans lesquelles est maintenue une extrémité 28A, respectivement 28B, de chacun des pions d'entraînement 22A, 22B. Ainsi, les amplitudes de ces pistes de cames 27A, 27B, sont définies de manière à pouvoir conférer, au travers de la coopération doigts d'entraînement 20, 21 - pions d'entraînement 22A, 22B, une course angulaire déterminée à chacun des secteurs dentés 11, 12. De manière préférentielle, ces pistes de cames 27A, 27B, en coopération avec les pions d'entraînement 22A, 22B, contribuent à la limitation en rotation de chacun des secteurs dentés 11, 12 au travers du fouillot 8.According to an advantageous embodiment, these cam tracks 27A, 27B are in the form of grooves on the inner side of these side walls 4A, 4B, grooves in which one end is held 28A, respectively 28B, of each of the pegs. 22A, 22B. Thus, the amplitudes of these cam tracks 27A, 27B are defined in such a way as to be able to confer, via the driving fingers 20, 21 - drive pins 22A, 22B, a determined angular stroke to each of the sectors teeth 11, 12. Preferably, these cam tracks 27A, 27B, in cooperation with the drive pins 22A, 22B, contribute to the limitation in rotation of each of the toothed sectors 11, 12 through the follower 8.

Préférentiellement, la somme des courses angulaires 18, 19, est définie de manière à pouvoir communiquer à la poignée de commande, agissant sur le fouillot 8, une rotation d'environ 180° se décomposant en la succession des deux courses 18,19, sensiblement équivalentes, de l'ordre de 90° permettant très facilement de distinguer, si nécessaire, un premier et un second mode d'ouverture comme c'est habituellement le cas pour les ferrures de type crémone ou crémone-serrures appliquées à des ouvrants oscillo-battants.Preferably, the sum of the angular races 18, 19, is defined so as to be able to communicate to the control handle, acting on the follower 8, a rotation of about 180 ° decomposing in the succession of the two races 18, 19, substantially equivalents, of the order of 90 ° making it very easy to distinguish, if necessary, a first and a second opening mode as is usually the case for cremone or espagnolette-lock type fittings applied to oscillating openings. leaves.

Cependant, l'on comprend bien que la présente invention n'est nullement limitée à une application à de tels ouvrants à modes d'ouverture multiples. Le gain en amplitude de rotation résultant de l'invention permet dans tous les cas, un gain au niveau de l'amplitude de déplacement d'organes de verrouillage tels que la tringle de manoeuvre et ceci en vue, par exemple, d'un verrouillage plus sécurisé. En particulier, une rotation limitée à 90° se traduisant par un moindre déplacement d'une tringle de manoeuvre peut conduire à un entraînement insuffisant d'organes de verrouillage pour garantir leur engagement dans leurs gâches respectives sur le cadre dormant d'une porte, fenêtre ou similaire. Ce problème peut être rencontré, tout particulièrement, lors de jeux de feuillure trop importants.However, it is well understood that the present invention is not limited to any application to such multiple opening apertures. The gain in amplitude of rotation resulting from the invention makes it possible in all cases, a gain in the amplitude of displacement of locking members such as the operating rod and this in view, for example, of a locking safer. In particular, a rotation limited to 90 ° resulting in less movement of a drive rod can lead to insufficient drive of locking members to ensure their engagement in their respective latches on the frame of a door, window or similar. This problem can be encountered, especially, during too big rabbet play.

Pour en revenir au mode de fonctionnement de la ferrure selon l'invention, partant d'une disposition tel qu'illustré dans la figure 3 que nous interpréterons comme étant une position de verrouillage total, une première rotation du fouillot 8 par la poignée de commande selon la première course 18, conduit, au travers du doigt d'entraînement le plus court 21 du demi-moyeu 13A, à l'entraînement du premier secteur denté 11, et ceci dans la mesure où le pion d'entraînement 22A se trouve, sous l'impulsion de la piste de came 27A, non visible sur les figures, repoussé dans sa première position 24, la plus proche de l'axe de rotation 9 du fouillot 8. Simultanément et comme visible dans la figure 4, à cette première rotation référencée D dans la figure 3 et cette figure 4, le demi-moyeu 13B vient tourner librement par rapport au second secteur denté 12, du fait du pion d'entraînement 22B, repoussé sous l'impulsion de la piste de came 27B, dans la seconde position 25, la plus éloignée de l'axe 9 de rotation du fouillot 8. Plus exactement, le doigt d'entraînement 21 de ce second demi-moyeu 13B, ne rencontre pas, dans sa trajectoire semi circulaire, le pion d'entraînement 22B.To return to the mode of operation of the fitting according to the invention, starting from a disposition as illustrated in FIG. figure 3 which we will interpret as being a total locking position, a first rotation of the follower 8 by the control handle according to the first race 18, leads, through the shortest driving finger 21 of the half-hub 13A, to the drive of the first toothed sector 11, and this to the extent that the drive pin 22A is, under the pulse of the cam track 27A, not visible in the figures, pushed back into its first position 24, the closest to the axis of rotation 9 of the follower 8. Simultaneously and as visible in the figure 4 , at this first rotation referenced D in the figure 3 and this figure 4 , the half-hub 13B rotates freely with respect to the second toothed sector 12, because of the driving pin 22B, pushed back under the impetus of the cam track 27B, in the second position 25, furthest from the 9 axis of rotation of the follower 8. More exactly, the drive finger 21 of the second half-hub 13B, does not meet, in its semi-circular trajectory, the drive pin 22B.

Par contre on voit bien sur cette figure 4 et plus particulièrement en se référant à la figure 6, qu'au delà de cette première course 18, de l'ordre de 90°, le doigt d'entraînement 20 de ce demi-moyeu 13B est venu en contact du pion d'entraînement 22B. Aussi, en poursuivant la rotation du fouillot 8, c'est-à-dire en exécutant la seconde course 19, ce doigt d'entraînement 20, en agissant sur ce pion d'entraînement 22B, entraîne en rotation le second secteur denté 12.By cons we can see on this figure 4 and more particularly by referring to the figure 6 , beyond that first race 18, of the order of 90 °, the drive finger 20 of the half-hub 13B has come into contact with the driving pin 22B. Also, by continuing the rotation of the follower 8, that is to say by executing the second race 19, this drive finger 20, acting on this drive pin 22B, rotates the second toothed sector 12.

Cependant, au cours de la première course 18, le déplacement angulaire du premier secteur denté 11 a conduit à repousser le pion d'entraînement 22A dans sa seconde position 25 sous l'impulsion de la piste de came 27A. De la sorte, ce pion d'entraînement 22A s'est vu écarter de la trajectoire du doigt d'entraînement 21 du demi-moyeu 13A qui peut alors poursuivre librement sa rotation, c'est-à-dire sous forme d'une course à vide 19 par rapport au premier secteur denté 11. Si, en soi, les parois du boîtier 4 peuvent contribuer à limiter les courses angulaires de chacun des secteurs dentés 11, 12, cette limitation en rotation peut encore découler des pistes de cames 27A, 27B, dont les extrémités peuvent définir des butées conçues aptes à coopérer avec les pions d'entraînement, respectivement 22A, 22B.However, during the first race 18, the angular displacement of the first toothed sector 11 has led to pushing the drive pin 22A in its second position 25 under the impetus of the cam track 27A. In this way, this drive pin 22A has been removed from the trajectory of the drive finger 21 of the half-hub 13A which can then freely continue its rotation, that is to say in the form of a race with vacuum 19 relative to the first toothed sector 11. If, per se, the walls of the housing 4 can contribute to limiting the angular races of each of the toothed sectors 11, 12, this rotation limitation can still result from the cam tracks 27A, 27B, whose ends can define designed stops adapted to cooperate with the drive pins, respectively 22A, 22B.

Selon une autre particularité encore de l'invention, chaque secteur denté 11, 12 est conçu apte à coopérer, à l'arrière de la face avant opposée à la rainure du boîtier 4, avec une portion de crémaillère 29, 30 équipant selon le cas, un chevalet de transmission 31 comme cela apparaît dans le mode de réalisation illustré ou, directement, une tringle de manoeuvre 5 dans sa partie introduite dans le boîtier 4. Dans la suite de la description, on se limitera à faire référence à un chevalet de transmission 31.According to another feature of the invention, each toothed sector 11, 12 is designed to cooperate, at the rear of the front face opposite to the groove of the housing 4, with a rack portion 29, 30 fitted as appropriate , a transmission bridge 31 as it appears in the illustrated embodiment or, directly, an operating rod 5 in its portion introduced into the housing 4. In the following description, it will be limited to refer to a bridge of transmission 31.

Tout particulièrement, la portion de crémaillère 30 est définie apte, sous l'impulsion du second secteur denté 12, à communiquer au chevalet de transmission 31, un déplacement qui constitue le prolongement du déplacement qui lui a été communiqué précédemment par le premier secteur denté 11 en coopération avec la première portion de crémaillère 29 et inversement.In particular, the rack portion 30 is defined able, under the impulse of the second toothed sector 12, to communicate to the transmission bridge 31, a displacement which constitutes the extension of the displacement communicated to it previously by the first toothed sector 11 in cooperation with the first rack portion 29 and vice versa.

Dans la mesure où les secteurs dentés 11, 12 sont décalés axialement au niveau du fouillot 8, les portions de crémaillère 29, 30 sont elles-mêmes décalées transversalement au niveau du chevalet de transmission 31, voire de la tringle de manoeuvre 5.Insofar as the toothed sectors 11, 12 are axially offset at the follower 8, the rack portions 29, 30 are themselves offset transversely at the level of the transmission bridge 31, or even of the operating rod 5.

En outre, chacune de ces portions de crémaillère 29, 30, est prolongée à son extrémité 34, 35 (non représentée sur les figures), du côté en direction de l'autre portion de crémaillère 30, 29, d'un segment de débrayage 32, 33 défini dans le mode de réalisation illustré, sous forme d'une rainure, mais qui pourrait encore emprunter la forme d'un décrochement, voire d'une ouverture au niveau du chevalet de transmission 31. Ce segment de débrayage a pour but le libre déplacement dudit chevalet de transmission 31 lors des courses à vide 18, 19 du fouillot 8, respectivement, par rapport au second secteur denté 12 et au premier secteur denté 11.In addition, each of these rack portions 29, 30, is extended at its end 34, 35 (not shown in the figures), on the side towards the other rack portion 30, 29, of a disengagement segment. 32, 33 defined in the illustrated embodiment, in the form of a groove, but which could still take the form of a recess, or an opening at the easel 31. The aim of this disengaging segment is the free movement of said transmission bridge 31 during the idle races 18, 19 of the follower 8, respectively, with respect to the second toothed sector 12 and the first tooth sector 11.

Finalement, comme on peut le constater, malgré un encombrement réservé au fouillot 8 de l'ordre de 180°, il peut être communiqué à ce fouillot 8 une rotation d'un angle supérieur à 90° et pouvant atteindre 180° voire davantage.Finally, as can be seen, despite a space reserved for the follower 8 of the order of 180 °, it can be communicated to this follower 8 a rotation of an angle greater than 90 ° and up to 180 ° or more.

Ainsi, la présente invention vient répondre, de manière avantageuse au problème posé.Thus, the present invention responds, advantageously to the problem.
