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 butée 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 destiné à recevoir 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 qui sont destinées à se déplacer dans ladite rainure; des moyens d'entraînement 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; lesdits moyens d'entraînement du fouillot avec la première tringle de verrouillage étant constitués par des dents qui font saillie du corps du fouillot et qui engrènent directement avec des orifices correspondants pratiqués dans l'extrémité proche du fouillot de la première tringle.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 abutting one against the other, said casing housing the '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 receive 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 which are intended to move in said groove; drive means 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; said means for driving the follower with the first locking rod being constituted by teeth which project from the body of the follower and which mesh directly with corresponding orifices made in the close end of the follower of the first rod.

On connaît par le EP-A-0009457 qui définit l'état de la technique conformément à l'Article 54(3) de la CBE et qui n'est pas pris en considération pour l'appréciation de l'activité inventive (Article 56 de la CBE), une crémone à larder pour un ouvrant de fenêtre, de ports 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 verrouil- tage 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. Les moyens d'entraînement du fouillot avec la première tringle de verrouillage sont constitués par des dents faisant saillie du corps du fouillot et engrènant 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 engrènant avec au moins un orifice correspondant pratiqué dans une bande flexible liée au fouillot, fixée à l'extrémité proche du fouillot de la seconde 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.We know from EP-A-0009457 which defines the state of the art in accordance with Article 54 (3) of the EPC and which is not taken into account for the assessment of inventive step (Article 56 of the EPC), a cremone bolt for a window, port or the like opening comprising a two-part casing joining in a longitudinal plane of the cremone bolt and bearing one against the other, said casing ensuring the housing 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 situated 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. The means for driving the follower with the first locking rod consist of teeth projecting from the body of the follower and engaging directly with corresponding orifices made in the near end of the follower of the first rod. The means for driving the follower with the second locking rod are constituted by at least one tooth projecting from the body of the follower and meshing with at least one corresponding orifice made in a flexible strip linked to the follower, fixed at 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.

On connaît également par le FR-A-1.345.596 une crémone à larder comportant un boîtier constitué par deux plaques identiques pliées sur trois côtés et rivetées 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.Also known from FR-A-1.345.596 is a latch bolt comprising a housing constituted by two identical plates folded on three sides and riveted to 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.

La présente invention a pour but d'obtenir un renvoi plus précis de la course que celui des crémones à double action connues tout en permettant une diminution des coûts et/ou une amélioration du fonctionnement. En plus, elle doit solutionner le problème consistent 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 obtain a more precise reference of the stroke than that of known double-action cremones while allowing a reduction in costs and / or an improvement in operation. In addition, it must solve the problem consisting in designing a double action latching bolt which is posed in a groove from the edge of the opening, while allowing the housing housing to be produced from the face of the opening. by a single drilling operation from the internal face of the opening.

Ce but est obtenu par l'invention en disposant entre les deux tringles un inverseur constitué d'une bande flexible en forme de boucle ouverte reliée de manière fixe par ses extrémités à chacune des tringles.This object is achieved by the invention by placing between the two rods an inverter consisting of a flexible strip in the form of an open loop fixedly connected by its ends to each of the rods.

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.This increase in the precision of the return of the race is particularly important when the cremone bolt comprises rods returned elsewhere, for example by means of angle references, on two or three edges of the opening.

D'autre part, l'invention permet 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.Furthermore, the invention makes it possible 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 FR-A-2010999 et FR-A-2214311 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 casing, or even an adaptation of the casing to a form known by FR-A-2010999 and FR-A-2214311 concerning single rod cremone bolts, is 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 de 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.As a result, it becomes possible to give the double-action cremone bolt casing the same shape as that of the single-action cremone bolt casings known by the French patents cited above, allowing its notching in the upright or the crosspiece of the opening for the installation of said cremones by a single drilling operation.

Les caractéristiques de l'invention présentent, par ailleurs, d'autres avantages. En effet, une bande 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 strip, guided in a guide corridor having at least at its ends straight sections of a length at least equal to that of the travel of the rods, creates the fundamental conditions for the flexible element, guided in the guide corridor has 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 la bande 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 deux tringles à relier entre elles ne 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 tel qu'indiqué dans le EP-A-0009457. En effet, si l'on agit sur une bande 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, considerably eases the deflection of the flexible strip 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 two rods to be connected together is only possible if these ends are guided in a straight section of guide corridor of a length at least equal to the distance of movement of the flexible element as indicated in EP-A-0009457. Indeed, if one acts on a flexible strip 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'une bande 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 22 of the first rod 19, by means of a bridge 21, fixes the end 22 of a flexible strip 23, the other end 24 of which is connected by means of a axis 25 at the end 26 of a second locking rod 27.

La bande 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 strip 23 includes a plurality of slots 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 .

La bande 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'une boucle ouverte, se compose d'une rainure circulaire 32 disposée concentriquement au fouillot 9 et de deux rainures droites 33, 34 parallèles entre elles et parallèles aux deux tringles 19 et 27. Ces deux rainures droites 33, 34 ont une longueur au moins égale à celle de la course des tringles 19, 27 de la crémone 1.The flexible strip 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 an open loop, consists of a circular groove 32 disposed concentrically with the follower 9 and two straight grooves 33, 34 parallel to each other and parallel to the two rods 19 and 27. These two straight grooves 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 rainure droite 34 du couloir de guidage 31 est rapprochée et juxtaposée à l'autre rainure droite 33.According to a characteristic of the invention, the right groove 34 of the guide passage 31 is brought together and juxtaposed with the other straight groove 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 F,, 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 second 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 F2. Bien entendu, en impliquant au fouillot 9 une rotation contraire, la première tringle 19 exerce une traction sur la bande flexible 23, traction transmise par ladite bande 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 ,, the teeth 12, 13, 14 imply a displacement 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 F 3 , 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 strip 23, traction transmitted by said flexible strip 23 to the second rod 27 which will move in the opposite direction relative to the first rod 19 .
