Description

L'invention concerne une crémone pour fenêtre, porte ou analogue à double action comportant deux tringles de verrouillage se déplaçant dans deux directions opposées par l'action d'un élément flexible reliant les deux tringles et coopérant avec un élément d'entraînement tel qu'un fouillot logé dans un boîtier.The invention relates to a cremone bolt for window, door or the like with double action comprising two locking rods moving in two opposite directions by the action of a flexible element connecting the two rods and cooperating with a drive element such as a follower housed in a box.

On connaît déjà, par le brevet allemand n° 318.213, une crémone pour fenêtre, porte ou analogue à double action dont deux tringles se déplacent dans deux directions opposées par l'action d'un élément flexible reliant les deux tringles et coopérant avec un élément d'entraînement. Selon ce brevet, les deux tringles sont toujours rappelées dans leur position de verrouillage. Elles ne peuvent pas prendre, soit une position d'ouverture, soit une position de verrouillage.Already known from German patent No. 318.213, a cremone bolt for window, door or the like with double action, two rods of which move in two opposite directions by the action of a flexible element connecting the two rods and cooperating with an element drive. According to this patent, the two rods are always returned to their locked position. They cannot take either an open position or a locked position.

Par ailleurs, la crémone est apparente et ne peut pas se larder, par exemple dans l'épaisseur d'un ouvrant. De plus, elle comporte un élément d'entraînement relié à une poignée avec un poussoir agissant perpendiculairement au plan de la fenêtre ou porte.Furthermore, the cremone bolt is visible and cannot be larded, for example in the thickness of an opening leaf. In addition, it includes a drive element connected to a handle with a pusher acting perpendicular to the plane of the window or door.

On connaît également des crémones à double action et à larder dont l'élément d'entraînement agit parallèlement au plan de la fenêtre. Une de ces crémones connues selon le brevet français n° 69.16771 (2.044.493) comporte une roue dentée disposée entre les deux tringles de la crémone pour inverser le mouvement de la première tringle dans un mouvement opposé de la seconde tringle.We also know double action cremone bolts and larder whose drive element acts parallel to the plane of the window. One of these cremones known according to French patent n ° 69.16771 (2.044.493) comprises a toothed wheel disposed between the two rods of the cremone bolt to reverse the movement of the first rod in an opposite movement of the second rod.

Toutefois, les crémones à double action avec un tel renvoi à engrenage présentent une différence de course relativement importante entre les tringles actionnées en sens opposé. Cette différence de course provient des jeux inévitables, d'une part, dans l'articulation de la roue dentée et, d'autre part, entre les dents de la roue dentée et les dents de chaque tringle, ces jeux étant inévitables du fait que, pour des raisons économiques, les pièces composant les crémones sont obtenues par découpage. Il s'ensuit également que le mouvement de la crémone est souvent un mouvement saccadé. L'inégalité de la course des deux tringles ainsi que le mouvement saccadé ont toujours été considérés par l'Homme de l'Art comme des handicaps amenuisant la notion de qualité de la crémone.However, double action cremone bolts with such a gear return have a relatively large stroke difference between the rods actuated in the opposite direction. This difference in stroke comes from the inevitable games, on the one hand, in the articulation of the toothed wheel and, on the other hand, between the teeth of the toothed wheel and the teeth of each rod, these games being inevitable because , for economic reasons, the parts making up the cremones are obtained by cutting. It also follows that the movement of the cremone bolt is often a jerky movement. The uneven running of the two rods as well as the jerky movement have always been considered resisted by the skilled person as handicaps reducing the notion of quality of the cremone bolt.

Par ailleurs, ces crémones comportent un boîtier d'une longueur assez importante nécessitant, lorsqu'elles sont à larder, la réalisation d'un logement long, par exemple dans le montant ou la traverse de l'ouvrant de fenêtre, porte ou analogue à verrouiller. Par conséquent, le boîtier de la crémone est relativement cher, nécessite un temps d'entaillage relativement long et pour la mise en place d'une telle crémone dans le montant ou la traverse d'un ouvrant on affaiblit la section et la résistance du montant ou de la traverse de l'ouvrant.Furthermore, these cremone bolts comprise a housing of a fairly considerable length requiring, when they are to be larded, the production of a long housing, for example in the upright or the cross member of the window opening, door or the like. lock. Consequently, the cremone bolt case is relatively expensive, requires a relatively long notching time and for the installation of such a cremone bolt in the upright or the cross member of an opening, the cross section and the resistance of the upright are weakened. or the cross member of the opening.

De plus, les boîtiers des crémones à double action et à larder connues nécessitent, de par leur longueur, un entaillage particulier. Ceci présente un inconvénient important lorsqu'un lot de fabrication d'ouvrants comporte deux types de fenêtres avec des crémones à simple action et avec des crémones à double action. Il s'ensuit que les coûts de fabrication sont plus élevés du fait qu'il est nécessaire de mettre deux séries différentes en oeuvre.In addition, the housings of known double action cremones and larders require, by their length, a particular notching. This has a significant drawback when a manufacturing batch of openings has two types of windows with single action cremone bolts and with double action cremone bolts. It follows that the manufacturing costs are higher because it is necessary to implement two different series.

La présente invention a pour but de remédier à ces inconvénients. L'invention, telle qu'elle est caractérisée dans les revendications, se propose de fournir une crémone à double action avec un fouillot agissant parallèlement au plan de la fenêtre et présentant, de ce fait, tous les avantages des crémones à double action manoeuvrées par poignée rotative, tout en obtenant un renvoi plus précis de la course que celui des crémones à double action connues et tout en permettant une diminution des coûts et/ou une amélioration du fonctionnement.The present invention aims to remedy these drawbacks. The invention, as characterized in the claims, proposes to provide a double action cremone bolt with a nut acting parallel to the plane of the window and therefore having all the advantages of double action cremone bolts operated by rotary handle, while obtaining a more precise reference of the stroke than that of known double action cremone bolts and while allowing a reduction in costs and / or an improvement in operation.

4 cet effet, l'invention prévoit que l'élément flexible est guidé dans un couloir de guidage réalisé dans le boîtier et présentant approximativement la forme d'un U dont les branches droites, parallèles entre elles, sont parallèles aux tringles et présentent une longueur au noins égale à celle de la course des tringles de la crémone.4 for this purpose, the invention provides that the flexible element is guided in a guide passage formed in the housing and having approximately the shape of a U whose straight branches, parallel to each other, are parallel to the rods and have a length at least equal to that of the cremone rod race.

Le remplacement du renvoi à engrenage par un renvoi à élément flexible permet de réduire pratiquement à rien la différence entre la course de chaque tringle. Cette augmentation de la précision du renvoi de la course est particulièrement importante lorsque la crémone comporte des tringles renvoyées par ailleurs, par exemple moyennant de renvois d'angle, sur deux ou trois bords de l'ouvrant.Replacing the gear return with a flexible element return virtually eliminates the difference between the travel of each rod. This increase in the precision of the reference of the stroke is particularly important when the cremone bolt has rods returned elsewhere, for example by means of angle references, on two or three edges of the opening.

D'autre part, l'invention se propose de réduire sensiblement la longueur du boîtier de la crémone. On obtient ce second avantage par une mesure qui se caractérise en ce que la partie courbée du couloir de guidage, située entre les deux branches parallèles, est disposée concentriquement au fouillot.On the other hand, the invention proposes to significantly reduce the length of the cremone bolt case. This second advantage is obtained by a measurement which is characterized in that the curved part of the guide passage, situated between the two parallel branches, is arranged concentrically with the follower.

En effet, cette mesure, selon l'invention, permet que l'élément de renvoi ne soit plus placé à distance du fouillot mais se superpose au fouillot. De ce fait, la longueur du boîtier peut être réduite.Indeed, this measure, according to the invention, allows the return element is no longer placed at a distance from the follower but is superimposed on the follower. As a result, the length of the housing can be reduced.

Une réduction plus importante encore du boîtier de la crémone, voire même une adaptation du boîtier à une forme connue par les brevets français n° 69.15947 (2.010.998) et n° 73.29611 (2.214.311) concernant des crémones à tringle unique, est obtenue par le fait que l'une des branches du couloir de guidage, présentant approximativement la forme d'un U, est rapprochée et juxtaposée à l'autre branche.An even greater reduction in the cremone bolt case, or even an adaptation of the case to a form known by French patents n ° 69.15947 (2.010.998) and n ° 73.29611 (2.214.311) concerning single rod cremones, obtained by the fact that one of the branches of the guide corridor, having approximately the shape of a U, is brought together and juxtaposed with the other branch.

De ce fait, il devient possible de donner au boîtier des crémones à double action la même forme que celle des boîtiers des crémones à simple action connues par les brevets français cités ci-dessus, permettant son entaillage dans le montant ou la traverse de l'ouvrant pour la mise en place desdites crémones par une opération unique de perçage.Therefore, it becomes possible to give the case of double action cremones the same shape as that of the housings of the single action cremones known by the French patents cited above, allowing its notching in the amount or the crosspiece of the opening for the installation of said cremone bolts by a single drilling operation.

Les caractéristiques de l'invention présentent, par ailleurs, d'autres avantages. En effet, un élément flexible, guidé dans un couloir de guidage présentant au moins à ses extrémités des tronçons droits d'une longueur au moins égale à celle de la course des tringles, crée les conditions fondamentales pour que l'élément flexible, guidé dans le couloir de guidage, comporte plusieurs lames superposées fixées ensemble à leurs extrémités aux tringles de verrouillage.The characteristics of the invention also have other advantages. Indeed, a flexible element, guided in a guide corridor having at least at its ends straight sections of a length at least equal to that of the rod travel, creates the fundamental conditions for the flexible element, guided in the guide corridor, comprises several superimposed blades fixed together at their ends to the locking rods.

L'emploi de plusieurs lames superposées, à la place d'une lame unique dans un couloir de guidage d'une épaisseur déterminée, assouplit considérablement le fléchissement de l'élément flexible et, par voie de conséquence, la douceur de fonctionnement de la crémone. Toutefois, l'utilisation de plusieurs lames superposées et la fixation commune de toutes les lames par leurs deux extrémités aux éléments à relier entre elles telles que les tringles sont uniquement possibles que si ces extrémités sont guidées dans un tronçon droit de couloir de guidage d'une longueur au moins égale à la distance de déplacement de l'élément flexible. En effet, si l'on agit sur un élément flexible composé de plusieurs lames superposées à un emplacement où cet élément flexible est engagé dans une courbure de son couloir de guidage, on déplace chaque lame d'une valeur différente du fait que la longueur de l'arc décrit par chaque lame est différente en raison de la différence de courbure entre les lames.The use of several superimposed blades, instead of a single blade in a guide corridor of a determined thickness, softens con considerably the deflection of the flexible element and, consequently, the smooth operation of the cremone bolt. However, the use of several superimposed blades and the common fixing of all the blades by their two ends to the elements to be connected together such as the rods are only possible if these ends are guided in a straight section of guide corridor. a length at least equal to the distance of displacement of the flexible element. Indeed, if one acts on a flexible element composed of several blades superimposed at a location where this flexible element is engaged in a curvature of its guide passage, each blade is displaced by a different value because the length of the arc described by each blade is different due to the difference in curvature between the blades.

Par conséquent, l'invention réalise,et ceci immédiatement par les premiers moyens qu'elle met en oeuvre, une conception technique permettant, à la fois, d'améliorer la précision du renvoi, de diminuer les coûts et d'améliorer le fonctionnement de la crémone.Consequently, the invention realizes, and this immediately by the first means which it implements, a technical design making it possible, at the same time, to improve the precision of the return, to reduce the costs and to improve the operation of the cremone bolt.

L'invention est exposée ci-après plus en détail à l'aide de dessins représentant seulement un mode d'exécution.The invention is set out below in more detail with the aid of drawings representing only one embodiment.

La figure 1 est une vue en coupe longitudinale du boîtier d'une crémone à double action conforme à l'invention ; la figure 2 est une vue en coupe selon la ligne de coupe II-II de la figure 1.Figure 1 is a longitudinal sectional view of the housing of a double action lever according to the invention; FIG. 2 is a sectional view along the section line II-II in FIG. 1.

On se réfère aux deux figures.We refer to the two figures.

La crémone à double action 1 comporte un boîtier 2 présentant une saillie centrale 3 disposée entre deux saillies latérales 4, 5 percées d'un trou taraudé 6, 7 pour recevoir les vis de fixation de la poignée. La saillie centrale 3 ayant une configuration circulaire renferme un logement circulaire 8 dans lequel est disposé un fouillot 9 présentant en son centre un carré d'entraînement 10.The double action cremone bolt 1 comprises a box 2 having a central projection 3 disposed between two lateral projections 4, 5 pierced with a tapped hole 6, 7 to receive the fixing screws of the handle. The central projection 3 having a circular configuration contains a circular housing 8 in which is disposed a follower 9 having in its center a drive square 10.

Le fouillot 9 comporte sur son pourtour circulaire 11 des dents d'entraînement 12, 13, 14 s'engrènant avec des orifices 15, 16, 17 pratiqués dans une des extrémités 18 d'une première tringle de verrouillage 19 se déplaçant parallèlement à une têtière 20. On fixe sur l'extrémité 18 de la première tringle 19, par l'intermédiaire d'un pontet 21, l'extrémité 22 d'un élément flexible 23 dont l'autre extrémité 24 est reliée par l'intermédiaire d'un axe 25 à l'extrémité 26 d'une seconde tringle de verrouillage 27.The follower 9 has on its circular periphery 11 drive teeth 12, 13, 14 meshing with orifices 15, 16, 17 formed in one of the ends 18 of a first locking rod 19 moving parallel to a headrest 20. The end 18 of the first rod 19 is fixed, by means of a bridge 21, the end 22 of a flexible element 23 whose other end 24 is connected by means of a pin 25 at the end 26 of a second locking rod 27.

L'élément flexible 23 comporte une pluralité de lumières 28, 29, 30 disposées dans un même plan vertical que les orifices 15, 16, 17 de la première tringle 19 et permettant le passage des dents d'entraînement 12, 13, 14 du fouillot 9.The flexible element 23 comprises a plurality of openings 28, 29, 30 arranged in the same vertical plane as the orifices 15, 16, 17 of the first rod 19 and allowing the passage of the drive teeth 12, 13, 14 of the follower 9.

L'élément flexible 23 se déplace dans un couloir de guidage 31 réalisé dans le boîtier 2 et plus particulièrement dans la saillie centrale 3. Ce couloir de guidage 31, ayant approximativement la forme d'un U, se compose d'une partie courbée 32 disposée concentriquement au fouillot 9 et de deux branches droites 33, 34 parallèles entre elles et parallèles aux deux tringles 19 et 27. Ces deux branches droites 33, 34 ont une longueur au moins égale à celle de la course des tringles 19, 27 de la crémone 1.The flexible element 23 moves in a guide passage 31 produced in the housing 2 and more particularly in the central projection 3. This guide passage 31, having approximately the shape of a U, consists of a curved part 32 disposed concentrically with the follower 9 and two straight branches 33, 34 parallel to one another and parallel to the two rods 19 and 27. These two straight branches 33, 34 have a length at least equal to that of the stroke of the rods 19, 27 of the cremone bolt 1.

Selon une caractéristique de l'invention, la branche droite 34 du couloir de guidage 31 est rapprochée et juxtaposée à l'autre branche droite 33.According to a characteristic of the invention, the straight branch 34 of the guide passage 31 is brought together and juxtaposed with the other straight branch 33.

Selon une variante, l'élément flexible 23 est composé d'une pluralité de lames superposées dont les extrémités sont fixées ensemble aux extrémités des deux tringles 19 et 27.According to a variant, the flexible element 23 is composed of a plurality of superimposed blades, the ends of which are fixed together at the ends of the two rods 19 and 27.

Le fonctionnement de la crémone est le suivant : en actionnant le fouillot 9 selon la flèche F1, les dents 12, 13, 14 impliquent à la première tringle 19 un déplacement selon la flèche F2. Lors de son déplacement, la première tringle 19 repousse l'élément flexible 23 qui transmet cette poussée à la seconde tringle 27. Cette seconde tringle 27 va se déplacer selon la flèche F3, la direction de la flèche F3 étant contraire à celle de la flèche F 2* Bien entendu, en impliquant au fouillot 9 une rotation contraire, la première tringle 19 exerce une traction sur l'élément flexible 23, traction transmise par ledit élément flexible 23 à la seconde tringle 27 qui se déplacera en sens contraire par rapport à la première tringle 19.The operation of the cremone bolt is as follows: by actuating the nut 9 according to the arrow F 1 , the teeth 12, 13, 14 imply a movement according to the arrow F 2 at the first rod 19. During its movement, the first rod 19 pushes the flexible element 23 which transmits this thrust to the second rod 27. This second rod 27 will move according to arrow F3, the direction of arrow F 3 being opposite to that of arrow F 2 * Of course, by involving the follower 9 in opposite rotation, the first rod 19 exerts traction on the flexible element 23, traction transmitted by said flexible element 23 to the second rod 27 which will move in opposite direction with respect to the first rod 19.
