Description

L'invention concerne une crémone à larder pour un ouvrant de fenêtre, de porte ou analogue comprenant un boîtier en deux parties se joignant dans un plan longitudinal de la crémone et venant en appui l'une contre l'autre, ledit boîtier assurant le logement d'un fouillot, ce dernier étant actionné par un organe de manoeuvre extérieur ; une têtière fixée rigidement sur le devant du boîtier qui est destinée à recouvrir une rainure longitudinale pratiquée sur le chant de l'ouvrant ; deux tringles de verrouillage situées approximativement sur la tangente au corps du fouillot et en prolongement l'une de l'autre et qui sont destinées à se déplacer dans ladite rainure ; des moyens d'entraînement agissant de part et d'autre du fouillot et transformant la rotation d'au moins un quart de tour du fouillot en une translation simultanée de course égale et dans des sens opposés de chacune des deux tringles de verrouillage.The invention relates to a cremone bolt for a window, door or the like opening comprising a casing in two parts joining in a longitudinal plane of the cremone bolt and bearing one against the other, said casing ensuring the accommodation a follower, the latter being actuated by an external operating member; a headrest rigidly fixed on the front of the housing which is intended to cover a longitudinal groove formed on the edge of the opening; two locking rods located approximately on the tangent to the body of the follower and in extension of one another and which are intended to move in said groove; drive means acting on either side of the follower and transforming the rotation of at least a quarter turn of the follower into a simultaneous translation of equal stroke and in opposite directions of each of the two locking rods.

On connaît par le brevet FR-A-1 345 596 une crémone à larder comportant un boîtier constitué par deux plaques identiques pliées sur trois côtés et rivetés sur une têtière. Ces plaques présentent deux douilles taraudées par la fixation d'une poignée. Dans ce boîtier est logé un fouillot fonctionnant de préférence en demi-tour et actionnant, d'une part, une première tringle de verrouillage et, d'autre part, une seconde tringle de verrouillage par l'intermédiaire d'un renvoi constitué par une petite tringle dont la course est limitée par le boîtier. La seconde tringle se déplace en sens contraire de la première.Patent FR-A-1 345 596 discloses a latch bolt comprising a casing constituted by two identical plates folded on three sides and riveted on a headrest. These plates have two threaded sockets by fixing a handle. In this housing is housed a follower preferably operating in a U-turn and actuating, on the one hand, a first locking rod and, on the other hand, a second locking rod by means of a return constituted by a small rod whose stroke is limited by the housing. The second rod moves in the opposite direction from the first.

Pour l'entaillage du logement du boîtier et des passages pour les moyens de liaison entre boîtier et poignée de cette crémone, il est nécessaire de procéder à deux opérations. En premier lieu, il faut fraiser, à partir du fond de la rainure recevant les tringles et leurs guides, cette rainure étant généralement pratiquée dans le chant de l'ouvrant de la fenêtre, porte ou analogue, un logement allongé destiné à recevoir le boîtier. Puis, dans une seconde phase, on perce, à l'aide d'une tête à mèches multiples, trois trous à partir de la face interne de l'ouvrant jusqu'au moment destiné à recevoir le boîtier de la crémone pour réaliser les passages nécessaires à la liaison entre le boîtier et la poignée devant actionner la crémone.For the notching of the housing of the housing and of the passages for the connection means between the housing and the handle of this cremone bolt, it is necessary to carry out two operations. Firstly, it is necessary to mill, from the bottom of the groove receiving the rods and their guides, this groove generally being practiced in the edge of the window opening, door or the like, an elongated housing intended to receive the housing. . Then, in a second phase, three holes are drilled, using a head with multiple wicks, from the internal face of the opening until the moment intended to receive the cremone bolt housing to make the passages. necessary for the connection between the housing and the handle which is to actuate the lever.

On connaît également par le brevet FR-A-2214311 une crémone à tringle unique. Cette crémone comporte un boîtier, composé de deux moitiés identiques, venant buter l'une contre l'autre selon un plan coïncidant avec l'axe médian longitudinal d'une têtière, dans lequel est monté un fouillot ayant la forme d'un pignon dont les dents s'engrènent avec des perforations réalisées dans une tringle de commande. Pour la mise en place de cette crémone dans un longeron d'ouvrant présentant une rainure pour la tringle de commande, on perce à partir de la face frontale du longeron trois formes. Les axes de ces trois formes sont disposés dans un même plan situé parallèlement à la direction longitudinale de la rainure et à une certaine distance du fond de cette rainure. Ainsi, le boîtier peut être placé dans un logement obtenu par une seule opération de perçage réalisée à partir de la face interne de l'ouvrant. Le ou les perçages, réalisés lors de cette opération, sont disposés de telle façon que leur paroi est coupée en sécante par le fond de la rainure recevant la tringle. Ainsi, on crée, d'une part, l'entaille pour le boîtier accessible à partir du chant de l'ouvrant et, d'autre part, les passages pour les moyens de liaison entre le boîtier et la poignée.Also known from patent FR-A-2214311 is a single rod cremone bolt. This cremone bolt comprises a housing, composed of two identical halves, abutting one against the other in a plane coinciding with the longitudinal median axis of a headrest, in which is mounted a nut having the shape of a pinion whose the teeth mesh with perforations made in a control rod. For the installation of this cremone bolt in a sash spar having a groove for the control rod, three shapes are drilled from the front face of the spar. The axes of these three forms are arranged in the same plane situated parallel to the longitudinal direction of the groove and at a certain distance from the bottom of this groove. Thus, the housing can be placed in a housing obtained by a single drilling operation carried out from the internal face of the opening. The hole (s) made during this operation are arranged in such a way that their wall is intersected by the bottom of the groove receiving the rod. Thus, one creates, on the one hand, the notch for the housing accessible from the edge of the opening and, on the other hand, the passages for the connecting means between the housing and the handle.

On connaît également, par le brevet FR-A-695868, un dispositif de fermeture à pêne déplacé par poussée au moyen d'une voie tournante placée dans un logement ayant une forme ronde et prolongé des deux côtés par des embouts creux dans lesquels se déplacent des chaînes servant d'élément de liaison entre la noix et des tringles de verrouillage. L'ensemble de ce logement comporte des pattes de fixation.Also known, from patent FR-A-695868, is a bolt closing device moved by pushing by means of a rotary track placed in a housing having a round shape and extended on both sides by hollow end caps in which move chains serving as a connecting element between the nut and locking rods. The whole of this housing has fixing lugs.

Toutefois, ce dispositif ne peut être utilisé en tant que crémone à larder logée dans une rainure pratiquée dans le chant de l'ouvrant. En effet, la crémone à larder comporte une têtière servant, d'une part, à couvrir la rainure et, d'autre part, de support non seulement au boîtier de la crémone mais également aux tringles de verrouillage. En voulant pourvoir ce dispositif, selon ce brevet, d'une têtière, soit la têtière est tangentielle au logement et les deux tringles de verrouillage se trouvent ainsi à une distance relativement importante de la face arrière de la têtière et il y a risque de flambage des tringles de verrouillage, soit la têtière coupe selon une sécante le logement et le dispositif, devient totalement inopérant.However, this device can not be used as a cremone bolt lodged housed in a groove made in the edge of the opening. Indeed, the cremone bolt has a headrest serving, on the one hand, to cover the groove and, on the other hand, as a support not only for the cremone bolt case but also for the locking rods. By wanting to provide this device, according to this patent, with a headrest, either the headrest is tangential to the housing and the two locking rods are thus at a relatively large distance from the rear face of the headrest and there is a risk of buckling. locking rods, that is to say the headrest cuts the housing and the device along a secant line, becomes totally inoperative.

La présente invention a pour but de solutionner le problème consistant à concevoir une crémone à larder à double action se posant dans une rainure à partir du chant de l'ouvrant tout en permettant une réalisation du logement du boîtier à partir de la face de l'ouvrant par une seule opération de perçage à partir de la face interne de l'ouvrant.The object of the present invention is to solve the problem of designing a double action latching rod which is posed in a groove from the edge of the opening while allowing the housing of the housing to be produced from the face of the opening by a single drilling operation from the internal face of the opening.

A cet effet, selon le concept inventif général de l'invention, il est nécessaire de réaliser une crémone plaçant les tringles, près de la têtière, tangentes ou approximativement tangentes au pourtour du fouillot, de disposer un tronçon de rainure droit d'au moins un couloir de guidage destiné à recevoir un élément flexible commandé par le fouillot en parallèle à au moins une tringle de verrouillage et de prévoir la disposition de l'élément flexible dans le tronçon de rainure concentrique tel que le parcours de l'élément flexible, lors d'une rotation du fouillot d'au moins un quart de tour, est disposé en dehors de l'espace occupé par l'élément reliant le fouillot à l'autre tringle qui peut être soit des orifices pratiqués à l'extrémité de ladite tringle engrenant avec des dents du fouillot soit un autre élément flexible de sorte que l'un des éléments flexibles puisse se déplacer sans entrer en collision avec l'élément reliant l'autre tringle lors d'une manoeuvre de fouillot d'au moins un quart de tour dans une crémone à larder comportant un boîtier entaillable par perçage.For this purpose, according to the general inventive concept of the invention, it is necessary to make a cremone bolt placing the rods, near the headrest, tangent or approximately tangent around the circumference of the follower, to have a straight groove section of at least a guide passage intended to receive a flexible element controlled by the follower in parallel with at least one locking rod and to provide the arrangement of the flexible element in the concentric groove section such that the path of the flexible element, during a rotation of the follower by at least a quarter of a turn, is arranged outside the space occupied by the element connecting the follower to the other rod which can either be orifices made at the end of said rod meshing with follower teeth is another flexible element so that one of the flexible elements can move without colliding with the element connecting the other rod during a follower maneuver of at least a quarter turn in a cremone bolt with a casing notched by drilling.

L'application des dispositions précitées permet de donner à la partie arrière du boîtier qui déborde le fond de la rainure pour les tringles et les guides, une forme ronde entaillable par perçage à partir de la face interne de l'ouvrant. En effet, la liaison entre le fouillot et au moins une tringle étant flexible, il devient possible de donner au boîtier une forme ronde tout en maintenant les tringles près de la têtière qui, généralement, les guide et les recouvre.The application of the aforementioned provisions makes it possible to give the rear part of the housing which projects beyond the bottom of the groove for the rods and the guides, a round shape which can be cut by drilling from the internal face of the opening. Indeed, the connection between the follower and at least one rod being flexible, it becomes possible to give the housing a round shape while maintaining the rods near the headrest which, generally, guides and covers them.

Par ailleurs, ces dispositions trouvent une application particulièrement avantageuse lorsque l'extrémité de l'élément flexible est guidée latéralement dans le tronçon droit, pour éviter tout flambage. L'extrémité de l'élément flexible est reliée par une de ses faces à ladite tringle de verrouillage. Ainsi, il est possible de réduire la longueur du boîtier d'une valeur égale à la longueur que nécessite un moyen de liaison disposé en prolongation de la tringle de verrouillage.Furthermore, these arrangements find a particularly advantageous application when the end of the flexible element is guided laterally in the straight section, to avoid any buckling. The end of the flexible element is connected by one of its faces to said locking rod. Thus, it is possible to reduce the length of the housing by a value equal to the length required by a connecting means arranged in extension of the locking rod.

D'autre part, ces dispositions permettent de donner aux boîtiers des crémones à deux tringles une configuration identique, dans l'essentiel, à celle connue des crémones à tringle unique dès lors que le couloir de guidage de l'élément flexible, reliant le fouillot à au moins une des tringles de verrouillage, est disposé en dehors de l'espace occupé par l'élément reliant le fouillot à l'autre tringle lors de la manoeuvre de la crémone.On the other hand, these provisions make it possible to give the housings of the rods with two rods a configuration identical, in essence, to that known of the rods with single rod since the guide passage of the flexible element, connecting the follower to at least one of the locking rods, is arranged outside the space occupied by the element connecting the follower to the other rod during the operation of the cremone bolt.

En effet, de ce fait, on permet que les tringles soient alignées tangentiellement au fouillot sans que les deux éléments de liaison, dont chacune relie le fouillot à une tringle, se gênent mutuellement lorsque le fouillot tourne d'au moins un quart de tour pour actionner les tringles. Par conséquent, il est ainsi possible de donner au boîtier une configuration identique à celle connue des crémones à tringle unique, de sorte que l'entaillage du boîtier des crémones à deux tringles ne puisse pas seulement se faire en une seule opération, mais également être identique à l'entaillage des crémones à tringle unique. Le travail du bois est, par conséquent, toujours identique, même si les séries de fabrication de fenêtre, porte ou analogue comprennent la pose de crémones à tringle unique et/ou de crémones à deux tringles.In fact, this allows the rods to be aligned tangentially to the follower without the two connecting elements, each of which connects the follower to a rod, interfering with each other when the follower turns at least a quarter of a turn to activate the rods. Consequently, it is thus possible to give the casing a configuration identical to that known for single rod cremone bolts, so that the notching of the casing for cremone bolts with two rods can not only be done in a single operation, but also be identical to the notching of the rods with single rod. Woodworking is therefore always the same, even if the window, door or similar manufacturing series include the installation of rods with single rods and / or rods with two rods.

Une première réalisation principale se caractérise, selon l'invention, en ce que les moyens d'entraînement du fouillot avec la première tringle de verrouillage sont constitués par des dents faisant saillie du corps du fouillot et engrenant directement avec des orifices correspondants pratiqués dans l'extrémité proche du fouillot de la première tringle ; les moyens d'entraînement du fouillot avec la deuxième tringle de verrouillage sont constitués par au moins une dent faisant saillie du corps du fouillot et engrenant avec au moins un orifice correspondant pratiqué dans un élément flexible lié au fouillot, fixée à l'extrémité proche du fouillot de la deuxième tringle et guidée dans un couloir réalisé dans le boîtier et se terminant par une rainure parallèle à la deuxième tringle de telle sorte que l'encombrement total du boîtier permette son montage dans l'épaisseur de l'ouvrant dans un logement entaillable par perçage à partir de la face intérieure de l'ouvrant.A first main embodiment is characterized, according to the invention, in that the drive means of the follower with the first locking rod are constituted by teeth projecting from the body of the follower and meshing directly with corresponding orifices made in the end close to the follower of the first rod; the means for driving the follower with the second locking rod consist of at least one tooth projecting from the body of the follower and meshing with at least one corresponding orifice formed in a flexible element linked to the follower, fixed to the end close to the follower of the second rod and guided in a corridor made in the housing and ending in a groove parallel to the second rod so that the total size of the housing allows its mounting in the thickness of the opening in a notch housing by drilling from the inside of the door.

Un premier avantage de cet aménagement latéral au fouillot du couloir de guidage réside dans le fait que la partie arrière du boîtier peut être de même grandeur que le logement circulaire du fouillot. Un deuxième avantage apparaît lorsque le fouillot est relié à chacune des deux tringles par un élément flexible. En effet, dans ce cas, les couloirs de guidage des deux éléments flexibles peuvent être disposés de part et d'autre du fouillot et comporter le même rayon pour obtenir une course identique des deux tringles. Cette dernière caractéristique est particulièrement avantageuse lorsque, pour des raisons de grandeur de rayon, les éléments flexibles sont, par exemple, des chaînes articulées.A first advantage of this arrangement lateral to the follower of the guide passage lies in the fact that the rear part of the housing can be of the same size as the circular housing of the follower. A second advantage appears when the follower is connected to each of the two rods by a flexible element. Indeed, in this case, the guideways of the two flexible elements can be arranged on either side of the follower and have the same radius to obtain an identical stroke of the two rods. This latter characteristic is particularly advantageous when, for reasons of radius size, the flexible elements are, for example, articulated chains.

Une seconde réalisation principale se caractérise, selon l'invention, en ce que les moyens d'entraînement du fouillot avec les deux tringles de verrouillage sont constitués par deux éléments flexibles, chacun étant, d'une part, ancré au fouillot et, d'autre part, fixé à l'extrémité proche du fouillot des tringles, les éléments flexibles étant guidés dans des couloirs réalisés dans le boîtier, lesdits couloirs comprenant une rainure circulaire autour du fouillot prolongée par deux rainures de courbures inverses se terminant par deux rainures droites opposées et parallèles aux tringles de verrouillage de telle sorte que l'encombrement total du boîtier permette son montage dans l'épaisseur de l'ouvrant dans un logement entaillable par perçage à partir de la face intérieure de l'ouvrant.A second main embodiment is characterized, according to the invention, in that the means for driving the follower with the two locking rods are constituted by two flexible elements, each being, on the one hand, anchored to the follower and, on the other hand, fixed to the end close to the rod follower, the flexible elements being guided in corridors made in the housing, said corridors comprising a circular groove around the follower extended by two reverse curved grooves ending in two opposite straight grooves and parallel to the locking rods so that the total size of the housing allows it to be mounted in the thickness of the opening in a housing notched by drilling from the inner face of the opening.

Cette conception s'applique de préférence aux éléments flexibles de faible épaisseur tels que lames en acier. Elle présente l'avantage que le ou les éléments flexibles peuvent comporter une largeur légèrement inférieure à la largeur du boîtier et, de ce fait, être. très résistants. Pour éviter toute superposition des deux éléments flexibles, ce qui entraînerait une différence entre les courses des deux tringles de verrouillage, l'invention propose une variante de cette réalisation qui se caractérise en ce que le second tronçon de rainure du couloir de guidage de l'élément flexible, reliant le fouillot à l'autre tringle, dont le rayon est inverse à la rainure concentrique, aboutit à un troisième tronçon de rainure de rayon à nouveau inversé dirigeant le couloir de guidage vers le tronçon de rainure droit, parallèle à l'autre tringle de verrouillage. En effet, ces caractéristiques permettent d'éviter toute collision entre les éléments flexibles, disposés dans un même plan avec le fouillot, en guidant chaque élément dans un couloir de guidage disposé en dehors de l'espace occupé par l'autre élément flexible lors d'une rotation du fouillot d'au moins un quart de tour, tout en faisant décrire à la rainure concentrique au fouillot et à la rainure de rayon inverse une courbure suivant le plus près possible une configuration de boîtier épousant parfaitement la configuration du logement réalisé par perçage à partir de la face interne de l'ouvrant. Une autre variante se caractérise, selon l'invention, en ce que les couloirs de guidage, pour deux éléments flexibles, sont constitués par une rainure circulaire dans laquelle débouchent, par un rayon de raccordement, deux paires de bretelles dont les sommets de jonction forment entre eux un angle approximatif de cent vingt degrés s'évasant vers des tronçons droits, parallèles aux tringles de verrouillage. Ainsi, il devient possible que le boîtier soit formé de deux moitiés identiques, ce qui réduit le coût de la fabrication et de l'outillage de la crémone.This design is preferably applied to flexible elements of small thickness such as steel blades. It has the advantage that the flexible element or elements may have a width slightly less than the width of the housing and, therefore, be. very resistant. To avoid any superposition of the two flexible elements, which would cause a difference between the races of the two locking rods, the invention proposes a variant of this embodiment which is characterized in that the second groove section of the guide corridor of the flexible element, connecting the follower to the other rod, the radius of which is opposite to the concentric groove, leads to a third section of again inverted ray groove directing the guide corridor towards the straight section of groove, parallel to the another locking rod. In fact, these characteristics make it possible to avoid any collision between the flexible elements, arranged in the same plane with the follower, by guiding each element in a guide corridor disposed outside the space occupied by the other element. flexible during a rotation of the follower by at least a quarter of a turn, while making the groove concentric with the follower and the groove of reverse radius describe a curvature as close as possible to a configuration of housing perfectly matching the configuration of the housing produced by drilling from the internal face of the opening. Another variant is characterized, according to the invention, in that the guideways, for two flexible elements, are constituted by a circular groove into which open, by a connection radius, two pairs of straps whose junction vertices form between them an approximate angle of one hundred and twenty degrees widening towards straight sections, parallel to the locking rods. Thus, it becomes possible that the housing is formed of two identical halves, which reduces the cost of manufacturing and tooling the cremone bolt.

Par ailleurs, la conception précitée rend possible que l'une des tringles de verrouillage comporte un élément de verrouillage disposé en regard à l'axe du fouillot lorsque la tringle de verrouillage se trouve à mi-course.Furthermore, the aforementioned design makes it possible for one of the locking rods to include a locking element disposed facing the axis of the follower when the locking rod is at mid-stroke.

D'autre part, les dispositions proposées par l'invention permettent de réaliser une réduction de la longueur du boîtier des crémones à larder. De ce fait, il est avantageux d'appliquer les dispositions de l'invention à toute crémone à larder, même si l'entaillage de son logement se réalise en deux opérations, par exemple en raison du matériau ou de la forme du profilé utilisé pour la fabrication de l'ouvrant.On the other hand, the arrangements proposed by the invention make it possible to achieve a reduction in the length of the housing of the cremones to be larded. Therefore, it is advantageous to apply the provisions of the invention to any rod to be larded, even if the notching of its housing is carried out in two operations, for example because of the material or the shape of the profile used for the manufacture of the opening.

On se réfère aux figures 1 et 2 montrant le travail du bois tel qu'il est connu pour l'entaillage permettant la mise en place du boîtier d'une crémone à tringle unique. Ce travail consiste à percer dans la face interne 1 de l'ouvrant 2, comportant dans son chant 3 une rainure 4 pour l'insertion de la têtière 5 et de la tringle 6 de la crémone 7, trois trous 8, 9, 10 d'une profondeur au moins égale à la distance 11 entre la paroi externe 12 de la rainure 4 et la face interne 1 de l'ouvrant 2. L'écartement entre les troux 8, 9, 10 ainsi que leur distance 13 du chant 3 sont donnés par la crémone 7 à poser. Les diamètres 14, 15, 16 des trous 8, 9, 10 sont choisis suffisamment grands afin que le fond 17 de la rainure 4 coupe les trous 8, 9, 10 selon une sécante et crée une ouverture 18, 19, 20 entre la rainure 4 et les trous 8, 9, 10 ou au moins entre la rainure 4 et le trou central 9. Parallèlement, ces diamètres 14, 15, 16 ou seulement le diamètre 15 du trou central 9, doivent permettre l'introduction de la partie arrière 21 du boîtier 22 de la crémone 7 qui déborde du fond 17 de la rainure 4.Reference is made to FIGS. 1 and 2 showing the working of the wood as it is known for notching allowing the installation of the casing of a single rod cremone bolt. This work consists in drilling in the internal face 1 of the opening 2, comprising in its edge 3 a groove 4 for the insertion of the headrest 5 and the rod 6 of the cremone bolt 7, three holes 8, 9, 10 d 'a depth at least equal to the distance 11 between the outer wall 12 of the groove 4 and the inner face 1 of the opening 2. The spacing between the holes 8, 9, 10 and their distance 13 from the edge 3 are given by the cremone bolt 7 to install. The diameters 14, 15, 16 of the holes 8, 9, 10 are chosen large enough so that the bottom 17 of the groove 4 cuts the holes 8, 9, 10 according to a secant and creates an opening 18, 19, 20 between the groove 4 and the holes 8, 9, 10 or at least between the groove 4 and the central hole 9. At the same time, these diameters 14, 15, 16 or only the diameter 15 of the central hole 9, must allow the introduction of the rear part 21 of the housing 22 of the cremone bolt 7 which projects from the bottom 17 of the groove 4.

On se réfère aux figures 3 et 4 montrant le boîtier 122 d'une crémone 107 à deux tringles de verrouillage 123, 124 actionnées par le fouillot 125 dans deux directions opposées. Ce boîtier 122 soit comporte, soit est fixé sur une têtière 105. Dans ce dernier cas, elle s'étend généralement sur toute la longueur du chant 3 de l'ouvrant 2. Ledit boîtier 122 comporte un logement circulaire 126 pour une rotation libre du fouillot 125 présentant en son centre un carré d'entraînement. La partie arrière 121 du boîtier 122 comporte une saillie centrale 127 ayant une configuration circulaire et épousant la circonférence du logement 126. Cette saillie centrale 127 se place dans le trou central 9 percé dans la face interne 1 de l'ouvrant 2 (voir figures 1 et 2). La partie arrière 121 du boîtier 122 comporte en plus, de part et d'autre et à égale distance de la saillie centrale 127, deux douilles latérales 128 et 129 percées d'un trou taraudé pour recevoir les vis de fixation de la poignée. Ces douilles latérales se logent dans les deux trous 8 et 10 (voir figures 1 et 2). Le fouillot 125 présente sur son pourtour extérieur 130 des dégagements laissant subsister les dents 131, 132, 133, 134 et 135. Les dents 131 et 132 sont engagées dans les orifices 136, 137 pratiqués dans une des extrémités 139 d'un élément flexible 140. L'autre extrémité 141 de l'élément flexible 140 est solidaire de l'extrémité 142 de la tringle de verrouillage 124 par une fixation latérale comprenant au moins un pontet 150 s'engageant dans un trou correspondant 151 réalisé dans l'extrémité 142 de la tringle de .verrouillage 124. Les dents 133, 134, 135, opposées aux dents 131 et 132, s'engrènent avec des orifices 143, 144, 145 réalisés dans l'extrémité 146 de l'autre tringle de verrouillage 123. En impliquant, par exemple, au fouillot 125 un mouvement de rotation selon la flèche F1' l'élément flexible 140 suit le même mouvement et exerce une poussée selon la flèche F2 sur la tringle de verrouillage 124 alors que le fouillot 125 exerce, par les dents 135, 134 et 133, une poussée selon la flèche F3 sur l'autre tringle de verrouillage 123. Ainsi, les déplacements des deux tringles 123, 124 sont de directions opposées. L'élément flexible 140 se déplace dans un couloir de guidage 100 réalisé dans le boîtier 122. Ce couloir de guidage 100 comprend une rainure 147 concentrique au fouillot 125 se prolongeant par une seconde rainure 148 d'un quart de cercle et de courbure inverse dirigeant le couloir de guidage 100 vers un tronçon de rainure droit 149, parallèle à la tringle 124. Le boîtier est formé de deux moitiés 171 et 172 symétriques par rapport au plan longitudinal médian de la crémone 107, ce qui permet d'utiliser la crémone soit à droite, soit à gauche.Referring to Figures 3 and 4 showing the housing 122 of a lever 107 with two locking rods 123, 124 actuated by the follower 125 in two opposite directions. This housing 122 either comprises or is fixed to a headrest 105. In the latter case, it generally extends over the entire length of the edge 3 of the opening 2. Said housing 122 comprises a circular housing 126 for free rotation of the follower 125 having in its center a square drive. The rear part 121 of the housing 122 has a central projection 127 having a circular configuration and matching the circumference of the housing 126. This central projection 127 is placed in the central hole 9 drilled in the internal face 1 of the opening 2 (see Figures 1 and 2). The rear part 121 of the housing 122 also comprises, on either side and at equal distance from the central projection 127, two lateral sockets 128 and 129 pierced with a tapped hole for receiving the fixing screws of the handle. These side sockets are housed in the two holes 8 and 10 (see Figures 1 and 2). The follower 125 has clearances on its outer periphery 130 leaving the teeth 131, 132, 133, 134 and 135. The teeth 131 and 132 are engaged in the orifices 136, 137 formed in one of the ends 139 of a flexible element 140 The other end 141 of the flexible element 140 is integral with the end 142 of the locking rod 124 by a lateral attachment comprising at least one bridge 150 engaging in a corresponding hole 151 produced in the end 142 of the locking rod 124. The teeth 133, 134, 135, opposite the teeth 131 and 132, mesh with orifices 143, 144, 145 made in the end 146 of the other locking rod 123. By involving, for example, in the nut 125 a rotational movement according to arrow F 1 ' the flexible element 140 follows the same movement and exerts a thrust according to arrow F 2 on the rod locking 124 while the follower 125 exerts, by the teeth 135, 134 and 133, a thrust according to arrow F 3 on the other locking rod 123. Thus, the movements of the two rods 123, 124 are in opposite directions. The flexible element 140 moves in a guide passage 100 produced in the housing 122. This guide passage 100 comprises a groove 147 concentric with the follower 125 extending by a second groove 148 of a quarter circle and of direct reverse curvature the guide passage 100 towards a straight groove section 149, parallel to the rod 124. The housing is formed of two halves 171 and 172 symmetrical with respect to the median longitudinal plane of the cremone pin 107, which makes it possible to use the cremone pin either right or left.

On se réfère aux figures 5 et 6. Selon cette variante, la crémone 207 comporte deux éléments flexibles 2401 et 2402 solidaires des tringles de verrouillage 223 et 224 par au moins un têton 250 engagé dans un trou 251. Les éléments flexibles 2401 et 2402 se déplacent dans deux couloirs de guidage 2001 et 2002 pratiqués dans le boîtier 222. Ces couloirs de guidage 2001 et 2002 sont obtenus en réalisant une rainure circulaire 252 et en faisant déboucher dans cette rainure circulaire 252, par un rayon de raccordement, quatre rainures 253, 254, 255, 256 sous forme de deux paires de bretelles dont les sommets de jonction 257, 258 forment entre eux un angle approximatif de cent vingts degrés dirigeant les couloirs de guidage 2001 et 2002 par des tronçons de rainure 259, 260 vers les tronçons de rainure droits 2491, 2492, Pour assurer l'entraînement de ces deux éléments flexibles 2401, 2402 et, par voie de conséquence, des deux tringles 223, 224, ces éléments flexibles 2401, 2402 comportent une extrémité recourbée 2611, 2612 venant se loger dans une fente 2621, 2622 pratiquée dans le fouillot 225. Les rayons de courbure des rainures 253 à 256 sont identiques au rayon de la rainure circulaire 252. De même, la somme des angles 263, 264 est égale à la somme des angles 265, 266, 267. Ceci permet d'utiliser des éléments flexibles 2401 et 2402 de même longueur et conception (voir figure 7). Selon l'invention, une des tringles de verrouillage 224 comporte un élément de verrouillage 268 disposé en regard de l'axe du fouillot 225, lorsque la tringle de verrouillage 224 se trouve à mi-course.Reference is made to FIGS. 5 and 6. According to this variant, the cremone bolt 207 comprises two flexible elements 240 1 and 240 2 secured to the locking rods 223 and 224 by at least one pin 250 engaged in a hole 251. The flexible elements 240 1 and 240 2 move in two guideways 200 1 and 200 2 made in the housing 222. These guideways 200 1 and 200 2 are obtained by making a circular groove 252 and by opening into this circular groove 252, by a connection radius, four grooves 253, 254, 255, 256 in the form of two pairs of straps whose junction vertices 257, 258 form between them an approximate angle of one hundred and twenty degrees directing the guideways 200 1 and 200 2 by groove sections 259, 260 towards the straight groove sections 249 1 , 249 2 , To ensure the driving of these two flexible elements 240 1 , 240 2 and, consequently, of the two rods 223, 224, these flexible elements 240 1 , 240 2 have a curved end 261 1 , 261 2 which is received in a slot 262 1 , 262 2 formed in the follower 225. The radii of curvature of the grooves 253 to 256 are identical to the radius of the circular groove 252. Likewise, the sum of the angles 263, 264 is equal to the sum of the angles 265, 266, 267. This makes it possible to use flexible elements 240 1 and 240 2 of the same length and design (see FIG. 7). According to the invention, one of the locking rods 224 comprises a locking element 268 disposed opposite the axis of the follower 225, when the locking rod 224 is at mid-stroke.

Le boîtier 222 est formé de deux moitiés identiques 271 et 272 pour réduire le coût de la fabrication et de l'outillage de la crémone. L'assemblage de ces deux moitiés identiques 271 et 272 se fait par emmanchement à force d'un têton 269 dans un trou 270, disposés tous les deux de même façon par rapport à l'axe de symétrie d'une moitié 271 ou 272.The housing 222 is formed from two identical halves 271 and 272 to reduce the cost of manufacturing and tooling the cremone bolt. The assembly of these two identical halves 271 and 272 is done by force fitting a stud 269 into a hole 270, both arranged in the same way with respect to the axis of symmetry of a half 271 or 272.

Comme visible dans les figures 3 à 6, le couloir de guidage 100, 2022 de l'élément flexible 140, 2402 reliant le fouillot 125, 225 à une des tringles de verrouillage 124, 224 est disposé en dehors de l'espace occupé par les dents 133, 134, 135 et élément flexible 2401 reliant le fouillot 125, 225 à l'autre tringle 123, 223 lors de la manoeuvre de la crémone. Ainsi, dans les figures 3 et 4 le couloir de guidage 100 est disposé latéralement et de part et d'autre des dents 133, 134, 135 reliant le fouillot 125 à la tringle 123. L'élément flexible 140 s'étend également de part et d'autre du fouillot 125 et comporte des raidisseurs sous forme de ponts 138 dont la largeur est inférieure à l'espace entre les dents 133, 134, 135. Par contre, dans les figures 5 et 6, le couloir de guidage 2002 est disposé extérieurement au secteur décrit par l'extrémité recourbée 2611 de l'élément 2401 reliant le fouillot 225 à l'autre tringle 223 lors de la manoeuvre de la crémone 207. De même que le couloir de guidage 2001 est disposé extérieurement au secteur décrit par l'extrémité recourbée 2612 de l'élément 2402 reliant le fouillot 225 à l'autre tringle 224 lors de la manoeuvre de la crémone 207.As shown in FIGS. 3 to 6, the guide passage 100, 202 2 of the flexible element 140, 240 2 connecting the follower 125, 225 to one of the locking rods 124, 224 is arranged outside the space occupied by the teeth 133, 134, 135 and flexible element 240 1 connecting the follower 125, 225 to the other rod 123, 223 during the operation of the cremone bolt. Thus, in Figures 3 and 4 the guide passage 100 is arranged laterally and on either side of the teeth 133, 134, 135 connecting the follower 125 to the rod 123. The flexible element 140 also extends from the and on the other side of the follower 125 and comprises stiffeners in the form of bridges 138 whose width is less than the space between the teeth 133, 134, 135. On the other hand, in FIGS. 5 and 6, the guide passage 200 2 is arranged outside the sector described by the curved end 261 1 of the element 240 1 connecting the follower 225 to the other rod 223 during the operation of the lever 207. Just as the guide passage 200 1 is disposed externally to the sector described by the curved end 261 2 of the element 240 2 connecting the follower 225 to the other rod 224 during the operation of the cremone bolt 207.

On se réfère aux figures 8 et 9 montrant le boîtier 322 d'une crémone 307 à deux tringles de verrouillage 323, 324 actionnées par le fouillot 325 dans deux directions opposées. Le boîtier 322, solidaire d'une têtière 305, comporte un logement circulaire 326 pour la rotation libre du fouillot 325. On pratique dans les deux moitiés 371 et 372, symétriques entre elles du boîtier 322, un couloir de guidage 300 dans lequel se déplace un élément flexible 340. Ce dernier peut être composé d'une pluralité de lames superposées dont une des extrémités 341 est solidaire de l'extrémité 342 de la tringle de verrouillage 324 par une fixation latérale comprenant au moins un pontet 350 s'engageant dans un trou correspondant 351 réalisé dans ladite extrémité 342. Le couloir de guidage 300 comprend, d'une part, une première rainure courbe 347 concentrique au fouillot 325 et, d'autre part, une seconde rainure courbe 348 de courbure inverse débouchant sur un tronçon de rainure droit 349 parallèle à la tringle 324. Les deux rainures courbes 347 et 348 sont reliées entre elles par un tronçon de rainure droit 373. La longueur de ce tronçon de rainure droit 373 est égale ou légèrement supérieure à la longueur de la course de la tringle 324. De ce fait, il est possible de remplacer l'élément flexible unique par une pluralité de lames flexibles superposées. Le tronçon de rainure courbe 347 concentrique au fouillot 325 du couloir de guidage 300 est dévié suivant une courbure en spirale vers le tronçon de rainure droit 373.Reference is made to FIGS. 8 and 9 showing the housing 322 of a cremone bolt 307 with two locking rods 323, 324 actuated by the follower 325 in two opposite directions. The housing 322, integral with a headrest 305, comprises a circular housing 326 for the free rotation of the follower 325. In the two halves 371 and 372, symmetrical to each other of the housing 322, there is a guide passage 300 in which moves a flexible element 340. The latter may be composed of a plurality of superimposed blades, one of the ends 341 of which is integral with the end 342 of the locking rod 324 by a lateral attachment comprising at least one bridge 350 engaging in a corresponding hole 351 made in said end 342. The guide passage 300 comprises, on the one hand, a first curved groove 347 concentric with the follower 325 and, on the other hand, a second curved groove 348 of reverse curvature leading to a section of straight groove 349 parallel to the rod 324. The two curved grooves 347 and 348 are connected together by a straight groove section 373. The length of this straight groove section 373 is equal or slightly nt greater than the length of the stroke of the rod 324. Therefore, it is possible to replace the single flexible element by a plurality of superimposed flexible blades. The curved groove section 347 concentric with the follower 325 of the guide passage 300 is deflected in a spiral curvature towards the straight groove section 373.

Le fouillot 325 comporte sur son pourtour extérieur 330 des dents 331, 333, 334 et 335. La dent 331 coopère avec l'orifice 336 pratiqué dans l'extrémité 339 de l'élément flexible 340 alors que les dents 333, 334 et 335 s'engrènent avec des orifices 343, 344, 345 réalisés dans l'extrémité 346 de l'autre tringle de verrouillage 323.The nut 325 has on its outer circumference 330 teeth 331, 333, 334 and 335. The tooth 331 cooperates with the orifice 336 formed in the end 339 of the flexible element 340 while the teeth 333, 334 and 335 s 'mesh with holes 343, 344, 345 made in the end 346 of the other locking rod 323.

Pour simplifier la conception des crémones actionnées par un quart de tour du fouillot, on prévoit également un autre mode d'exécution. On se réfère aux figures 10 et 11.To simplify the design of the cremones actuated by a quarter turn of the follower, we also provides for another mode of execution. We refer to Figures 10 and 11.

Selon l'invention, le fouillot 425 comporte trois dents 433, 434, 435 s'engrenant avec des trous 443, 444, 445 réalisés dans l'extrémité 446 de l'une des tringles de verrouillage 423 de la crémone 407, cette tringle 423 coulissant parallèlement à la têtière 405. Par ailleurs, le fouillot 425 comporte un doigt de commande 475 présentant une lumière 476 disposée radialement dans ledit fouillot 425. Dans cette lumière 476 coulisse un axe 477 solidaire de la face supérieure 478 d'une des extrémités 439 d'un élément flexible 440 dont l'autre extrémité 441 est reliée par l'intermédiaire d'un pontet 450 à l'extrémité 442 de la tringle de verrouillage 424.According to the invention, the follower 425 has three teeth 433, 434, 435 meshing with holes 443, 444, 445 made in the end 446 of one of the locking rods 423 of the cremone bolt 407, this rod 423 sliding parallel to the headrest 405. Furthermore, the follower 425 comprises a control finger 475 having a slot 476 disposed radially in said follower 425. In this slot 476 slides an axis 477 integral with the upper face 478 of one of the ends 439 a flexible element 440, the other end 441 of which is connected by means of a bridge 450 to the end 442 of the locking rod 424.

L'élément flexible 440 coulisse dans un couloir de guidage 400 réalisé dans les deux moitiés 471, 472 du boîtier 422 de la crémone 407. Ce couloir de guidage 400 comporte un premier tronçon de rainure droit 479. Ce tronçon de rainure 479 est perpendiculaire à un des diamètres 480 du fouillot 425. Par ailleurs, on pratique dans les deux moitiés 471, 472 du boîtier 422 une rainure droite 481, 482 parallèle au tronçon de rainure droit 479 dans laquelle coulisse l'axe 477. Au cours de la rotation du fouillot 425, l'extrémité 439 de l'élément flexible 440 coulisse dans le tronçon de rainure droit 479 alors que l'axe 477 se déplace dans la rainure droite 481, 482 en se rapprochant du centre 483 du fouillot 425 et en coulissant dans la lumière 476 du doigt de commande 475 du fouillot 425. La position « A de l'axe 477 la plus proche du centre 483 est située sur la médiatrice 484 du tronçon de rainure droit 479 passant par ledit centre 483.The flexible element 440 slides in a guide passage 400 produced in the two halves 471, 472 of the housing 422 of the cremone bolt 407. This guide passage 400 has a first straight groove section 479. This groove section 479 is perpendicular to one of the diameters 480 of the follower 425. Furthermore, in the two halves 471, 472 of the housing 422, a straight groove 481, 482 parallel to the straight groove section 479 in which the axis 477 slides. During the rotation of the follower 425, the end 439 of the flexible element 440 slides in the straight groove section 479 while the axis 477 moves in the straight groove 481, 482 approaching the center 483 of the follower 425 and sliding in the light 476 of the control finger 475 of the follower 425. The position "A of the axis 477 closest to the center 483 is located on the perpendicular bisector 484 of the straight groove section 479 passing through said center 483.

Le premier tronçon de rainure droit 479 aboutit à un second tronçon de rainure courbé 485 raccordant ce premier tronçon de rainure droit 479 à un troisième tronçon de rainure droit 486, ce dernier tronçon de rainure droit 486 étant parallèle à la tringle de verrouillage 424.The first straight groove section 479 ends in a second curved groove section 485 connecting this first straight groove section 479 to a third straight groove section 486, this last straight groove section 486 being parallel to the locking rod 424.

Les modes de réalisation représentés dans les figures 8 à 11 permettent l'utilisation d'un élément flexible composé de plusieurs lames superposées. En effet, lorsque l'élément flexible est composé de plusieurs lames superposées, chaque lame ayant une longueur égale au développement de la partie du couloir qu'elle occupe, il se produit un décalage entre les lames dans le sens de la longueur au moment où ces lames sont déplacées dans le couloir de guidage et passent d'un tronçon de rainure courbé à un autre tronçon de rainure courbé de rayon inverse.The embodiments shown in Figures 8 to 11 allow the use of a flexible element composed of several superimposed blades. Indeed, when the flexible element is composed of several superimposed blades, each blade having a length equal to the development of the part of the corridor that it occupies, there is a shift between the blades in the direction of the length when these blades are moved in the guide passage and pass from a curved groove section to another curved groove section of reverse radius.

Il s'ensuit qu'un élément flexible, composé de plusieurs lames superposées, ne peut, à au moins une de ses extrémités, être relié au fouillot ou à la tringle que par une seule lame. Si l'on voulait relier toutes les lames de l'élément flexible au fouillot ou à la tringle, les différentes lames feraient une boucle et coinceraient l'élément flexible dans le couloir de guidage.It follows that a flexible element, composed of several superimposed blades, can, at at least one of its ends, be connected to the follower or the rod only by a single blade. If one wanted to connect all the blades of the flexible element to the nut or the rod, the various blades would form a loop and would wedge the flexible element in the guide corridor.

La fragilité d'une liaison par l'une des lames d'un élément flexible composé de plusieurs lames augmente en fonction du nombre des lames d'une épaisseur d'autant plus faible, utilisées pour augmenter la souplesse et la flexibilité de l'élément flexible.The fragility of a connection by one of the blades of a flexible element made up of several blades increases as a function of the number of blades of an even thinner thickness, used to increase the suppleness and the flexibility of the element. flexible.
