Description

L'invention concerne une crémone à larder pour un ouvrant de fenêtre, 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 présentant une partie arrière lardée dont la configuration permet un entaillage dans le longeron de l'ouvrant par perçage frontal ; une têtière fixée rigidement sur le devant du boîtier et destinée à recouvrir une rainure longitudinale pratiquée dans le chant de l'ouvrant ; deux tringles de verrouillage se déplaçant dans ladite rainure et situées approximativement sur la tangente au corps d'un fouillot et en prolongement l'une de l'autre ; un fouillot, logé dans le boîtier et actionné par un organe extérieur de manoeuvre, dont le corps est pourvu sur sa circonférence extérieure de dents coopérant directement ou indirectement avec les extrémités des tringles de verrouillage et transformant la rotation d'au moins un quart de tour du fouillot en une translation simultanée de course égale mais de 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 having a rear part larded, the configuration of which allows notching in the side member of the opening by front drilling; a headrest rigidly fixed on the front of the housing and intended to cover a longitudinal groove formed in the edge of the opening; two locking rods moving in said groove and located approximately on the tangent to the body of a follower and in extension of one another; a follower, housed in the housing and actuated by an external operating member, the body of which is provided on its external circumference with teeth cooperating directly or indirectly with the ends of the locking rods and transforming the rotation by at least a quarter turn of the follower in a simultaneous translation of equal but opposite directions of each of the two locking rods.

On connaît déjà, par le document EP-B1-0 009 457, une crémone à larder telle que décrite dans le paragraphe précédent et dont les caractéristiques essentielles sont reprises dans le préambule de la revendication 1. La coopération indirecte entre les dents disposées sur le pourtour du corps du fouillot et l'extrémité de l'une des tringles de verrouillage se fait par l'intermédiaire d'un élément flexible.Already known from document EP-B1-0 009 457, a latch bolt as described in the previous paragraph and whose essential characteristics are included in the preamble of claim 1. The indirect cooperation between the teeth arranged on the around the body of the follower and the end of one of the locking rods is made by means of a flexible element.

Il est aussi connu du FR-A-2.356 794 une crémone actionnée par les dents d'un fouillot et un pignon inverseur auxiliaire, les extrémités des tringles s'entrecroisant, mais cette crémone nécessite un entaillage de dimension importante à partir du chant de l'ouvrant et ne permet donc pas un montage frontal au moyen d'un entaillage par perçage frontal dans le longeron de l'ouvrant.It is also known from FR-A-2,356,794 a cremone bolt actuated by the teeth of a follower and an auxiliary reversing pinion, the ends of the rods intersecting, but this cremone bolt requires a large dimension from the edge of the opening and therefore does not allow a front mounting by means of a notching by front drilling in the side member of the opening.

Pour pouvoir impliquer aux tringles une course donnée, le fouillot doit avoir un diamètre primitif développant cette course. Ce dit diamètre, augmenté de l'épaisseur de l'élément flexible et de l'épaisseur de la paroi de son couloir de guidage, conditionne la configuration de la partie arrière du boîtier et, par conséquent, le diamètre du perçage pour l'entaillage de la partie arrière centrale du boîtier. De même, la configuration de la partie arrière du boîtier est dépendante de la courbure de l'élément flexible. Cette courbure ne peut présenter un rayon inférieur à un certain rayon minimum pour que l'élément flexible ne subisse pas de modification de structure par une répétition de pliures inversées et glisse facilement dans le couloir de guidage du boîtier.In order to be able to involve a given stroke in the rods, the follower must have a pitch diameter developing this stroke. Said diameter, increased by the thickness of the flexible element and the thickness of the wall of its guide passage, conditions the configuration of the rear part of the housing and, consequently, the diameter of the hole for notching. from the central rear part of the housing. Similarly, the configuration of the rear part of the housing is dependent on the curvature of the flexible element. This curvature cannot have a radius less than a certain minimum radius so that the flexible element does not undergo a modification of structure by a repetition of inverted folds and slides easily in the guide corridor of the housing.

Cependant, il est avantageux que la partie arrière centrale du boîtier s'insère dans un perçage dont le diamètre se rapproche le plus près que possible du diamètre extérieur du fouillot.However, it is advantageous for the central rear part of the housing to be inserted into a borehole whose diameter is as close as possible to the outside diameter of the follower.

La présente invention a pour but de remédier à ces inconvénients. L'invention, telle qu'elle est caractérisée dans les revendications, résout le problème consistant à créer une crémone à larder pour un ouvrant de fenêtre, porte ou analogue du type décrit dans le EP-B1-0 009 457 dans laquelle les dents du fouillot comportent une épaisseur s'étendant sur la plus grande partie de la largeur du boîtier dont les parois ont une épaisseur suffisante pour servir de paliers à l'arbre du fouillot; l'extrémité de la première tringle de verrouillage comporte une denture tangente au corps du fouillot s'engrènant directement avec une partie de l'épaisseur des dents du fouillot et l'extrémité de la seconde tringle de verrouillage comporte une denture tangente à la circonférence extérieure du fouillot s'engrénant sur l'autre partie de l'épaisseur des dents du fouillot par l'intermédiaire d'au moins un pignon inverseur placé entre le fouillot et l'extrémité de la seconde tringle de verrouillage, à l'intérieur de la rainure longitudinale dans laquelle se placent le boîtier et les tringles de verrouillage.The present invention aims to remedy these drawbacks. The invention, as characterized in the claims, solves the problem of creating a cremone bolt for a window, door or the like opening of the type described in EP-B1-0 009 457 in which the teeth of the follower have a thickness extending over the greater part of the width of the housing, the walls of which have a thickness sufficient to serve as bearings for the follower shaft; the end of the first locking rod has a toothing tangent to the body of the follower meshing directly with part of the thickness of the teeth of the follower and the end of the second locking rod has a toothing tangent to the outer circumference of the follower meshing on the other part of the thickness of the teeth of the follower by means of at least one reversing pinion placed between the follower and the end of the second locking rod, inside the longitudinal groove in which the housing and the locking rods are placed.

Les avantages obtenus grâce à cette invention consistent essentiellement en ce que la crémone à larder à double action se pose 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 et dont le diamètre de la partie arrière centrale est identique ou approximativement identique au diamètre extérieur du fouillot.The advantages obtained thanks to this invention consist essentially in that the double action latching rod is placed 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 and whose diameter of the central rear part is identical or approximately identical to the external diameter of the follower.

Pour augmenter le diamètre du pignon inverseur, l'invention prévoit que la têtière est déportée dans un plan parallèle, sur approximativement la longueur du boîtier, d'une valeur inférieure au jeu de feuillure de la fenêtre, porte ou analogue et que l'extrémité de la seconde tringle de verrouillage est déportée dans un plan parallèle à la partie déportée de la têtière.To increase the diameter of the reversing pinion, the invention provides that the headrest is offset in a parallel plane, over approximately the length of the housing, by a value less than the clearance of the window rebate, door or the like and that the end of the second locking rod is offset in a plane parallel to the offset portion of the headrest.

De plus, selon l'invention, une meilleure transmission entre le fouillot et l'extrémité de la seconde tringle de verrouillage est réalisée en concevant que la longueur de la denture de l'extrémité de la seconde tringle de verrouillage est telle que la denture s'engrène avec deux pignons inverseurs disposés de part et d'autre du fouillot.In addition, according to the invention, better transmission between the follower and the end of the second locking rod is achieved by conceiving that the length of the toothing from the end of the second locking rod is such that the toothing s '' meshes with two reverse gears arranged on either side of the follower.

Selon un autre mode de réalisation de l'invention, la place disponible pour le pignon inverseur et les tringles peut être augmentée davantage lorsque la têtière est supprimée entre les emplacements de fixation du boîtier sur la têtière et que l'emplacement ainsi dégagé est recouvert de part et d'autre par un retour de chaque partie du boîtier.According to another embodiment of the invention, the space available for the reversing pinion and the rods can be increased further when the headrest is removed between the locations for fixing the housing to the headrest and the location thus cleared is covered with on both sides by a return of each part of the housing.

La solidité du pignon inverseur est renforcée par une caractéristique selon laquelle l'arbre et la couronne dentée du pignon inverseur font une seule pièce.The solidity of the reversing pinion is reinforced by a characteristic according to which the shaft and the toothed crown of the reversing pinion form a single piece.

On se réfère aux figures 1 à 7.We refer to Figures 1 to 7.

La crémone à larder 1 pour un ouvrant de fenêtre, de porte ou analogue se pose dans une rainure longitudinale pratiquée dans le chant de l'ouvrant. Cette crémone à larder 1 comporte un boîtier 2 dont l'embase se place dans ladite rainure longitudinale et la partie arrière lardée dans un logement réalisé à partir de la face de l'ouvrant et obtenu par une seule opération de perçage pratiquée dans la face interne de l'ouvrant. Sur le devant 3 du boîtier 2 est fixée, d'une manière rigide, une têtière 4 destinée à recouvrir la rainure longitudinale pratiquée dans le chant de l'ouvrant.The cremone bolt 1 for a window, door or similar opening arises in a longitudinal groove made in the edge of the opening. This cremone bolt 1 comprises a box 2, the base of which is placed in said longitudinal groove and the rear part larded in a housing produced from the face of the opening and obtained by a single drilling operation carried out on the internal face. of the opening. On the front 3 of the housing 2 is fixed, in a rigid manner, a headrest 4 intended to cover the longitudinal groove formed in the edge of the opening.

Le boîtier 2 est réalisé en deux parties 5, 6 se joignant dans un plan longitudinal 7 de la crémone à larder 1. Ces deux parties 5, 6 parallèles entre elles sont perpendiculaires à la têtière 4 et comportent deux parois 8, 9 présentant sur leur chant arrière 10 une partie lardée 11. Celle-ci présente une configuration telle qu'elle permet ladite opération de perçage frontal pratiqué dans la face interne de l'ouvrant. Avantageusement, cette configuration présente approximativement la forme d'un disque coupé selon une sécante solidaire des parois 8, 9 et faisant saillie par rapport au chant arrière 10. Entre les faces internes 12, 13 des parois 8, 9 est disposé un fouillot 14 actionné par un organe de manoeuvre extérieur (non représenté). Le fouillot 14 se compose d'un corps 15 et d'un arbre 16 faisant saillie par rapport aux deux faces 17, 18 du corps 15 du fouillot 14. Les extrémités 19, 20 de cet arbre 16 sont logées dans des alésages 21, 22 réalisés dans les parois 8, 9. L'épaisseur de ces dernières est telle que les parois 8, 9 servent de palier à l'arbre 16 du fouillot 14. L'épaisseur 23 du corps 15 du fouillot 14 est pratiquement identique à l'espace séparant les faces internes 12, 13 des parois 8, 9. Le diamètre du corps 15 du fouillot 14 est tel que sa circonférence extérieure 24 est pratiquement à fleur avec le chant arrière 25, 26 des parois 8, 9. Du fait que le corps 15 du fouillot 14 est pratiquement égal à l'espace séparant les faces internes 12, 13 des parois 8, 9 du boîtier 2, le fouillot 14 rigidifie le boîtier 2 et annihile tout écrasement des deux parois 8, 9. Le fouillot 14 comporte sur sa circonférence extérieure 24 des dents 27, 28 s'étendant sur toute l'épaisseur du corps 15.The housing 2 is made in two parts 5, 6 joining in a longitudinal plane 7 of the cremone bolt 1. These two parts 5, 6 parallel to each other are perpendicular to the headrest 4 and have two walls 8, 9 having on their rear edge 10 a larded part 11. This has a configuration such that it allows said front drilling operation carried out in the internal face of the opening. Advantageously, this configuration has approximately the shape of a disc cut according to a secant secured to the walls 8, 9 and projecting with respect to the rear edge 10. Between the internal faces 12, 13 of the walls 8, 9 is disposed an actuator 14 actuated by an external operating member (not shown). The follower 14 is made up of a body 15 and a shaft 16 projecting with respect to the two faces 17, 18 of the body 15 of the follower 14. The ends 19, 20 of this shaft 16 are housed in bores 21, 22 made in the walls 8, 9. The thickness of the latter is such that the walls 8, 9 serve as a bearing for the shaft 16 of the follower 14. The thickness 23 of the body 15 of the follower 14 is practically identical to the space separating the internal faces 12, 13 from the walls 8, 9. The diameter of the body 15 of the follower 14 is such that its outer circumference 24 is practically flush with the rear edge 25, 26 of the walls 8, 9. Because the body 15 of the follower 14 is practically equal to the space separating the internal faces 12, 13 of the walls 8, 9 of the housing 2, the follower 14 stiffens the housing 2 and eliminates any crushing of the two walls 8, 9. The follower 14 comprises on its outer circumference 24 of the teeth 27, 28 extending over the entire thickness of the body 15.

La crémone à larder 1 comporte également deux tringles de verrouillage 29, 30 situées approximativement sur la tangente au corps 15 du fouillot 14. Ces deux tringles de verrouillage 29, 30 sont disposées dans le prolongement l'une de l'autre et se déplacent en sens contraire dans la rainure longitudinale pratiquée dans le chant de l'ouvrant. Chaque tringle de verrouillage 29, 30 comporte une extrémité 31, 32 de largeur réduite par rapport à la largeur normale des tringles de verrouillage 29, 30. De ce fait, ces extrémités 31, 32 peuvent s'entrecroiser et comportent chacune sur sa face supérieure 33, 34 une denture 35, 36 coopérant soit directement, soit indirectement avec les dents 27, 28 du fouillot 14.The cremone bolt 1 also has two locking rods 29, 30 located approximately on the tangent to the body 15 of the nut 14. These two locking rods 29, 30 are arranged in the extension of one another and move in opposite direction in the longitudinal groove made in the edge of the door. Each locking rod 29, 30 has one end 31, 32 of reduced width compared to the normal width of the locking rods 29, 30. Therefore, these ends 31, 32 can intersect and each have on its upper face 33, 34 a toothing 35, 36 cooperating either directly or indirectly with the teeth 27, 28 of the follower 14.

A cet effet, l'extrémité 31 de la première tringle de verrouillage 29 comporte une denture 35 tangente au corps 15 du fouillot 14. Comme visible dans les figures 2, 6 et 7, cette denture 35 s'engrène directement avec une partie 37 de l'épaisseur des dents 27, 28 du fouillot 14. Cette tringle de verrouillage 29 se déplace à travers une ouverture 38 réalisée dans l'extrémité 39 du boîtier 2 et coulisse sur un retour 40 solidaire de l'une des parties 6 du boîtier 2.To this end, the end 31 of the first locking rod 29 has a toothing 35 tangent to the body 15 of the follower 14. As can be seen in FIGS. 2, 6 and 7, this toothing 35 meshes directly with a part 37 of the thickness of the teeth 27, 28 of the follower 14. This locking rod 29 moves through an opening 38 produced in the end 39 of the housing 2 and slides on a return 40 integral with one of the parts 6 of the housing 2 .

Par contre, l'extrémité 32 de la seconde tringle de verrouillage 30 comporte une denture 36 tangente au pourtour du fouillot 14, c'est-à-dire que la denture 36 est tangente à la circonférence extérieure 24 des dents 27, 28 du fouillot 14. Cette denture 36 coopère indirectement avec l'autre partie 41 de l'épaisseur des dents 27, 28 du fouillot 14. Cette tringle de verrouillage 30 se déplace à travers une ouverture 42 réalisée dans l'autre extrémité 43 du boîtier 2 et coulisse le long de la face arrière 44 de la têtière 4. On intercale entre le fouillot 14 et la seconde tringle de verrouillage 30 au moins un pignon inverseur 45 s'engrénant, d'une part, avec les dents 27, 28 du fouillot 14 et, d'autre part, avec la denture 36 de l'extrémité 32 de la seconde tringle de verrouillage 30. Par suite de la présence de ce pignon inverseur 45, la seconde tringle de verrouillage 30 se déplace en sens contraire par rapport à la première tringle de verrouillage 29. Ce pignon inverseur 45 constitue le moyen de coopération indirecte entre le fouillot 14 et l'extrémité 32 de la seconde tringle de manoeuvre 30. Conformément à l'invention, ce moyen de coopération indirecte est situé à l'intérieur de la rainure longitudinale pratiquée dans le chant de l'ouvrant et dans laquelle sont logés le boîtier 2 et les tringles de verrouillage 29, 30. Le pignon inverseur 45 comporte un arbre 46 dont les extrémités 47, 48 sont engagées dans les alésages 49, 50 réalisés dans les parois 8, 9 (voir figure 6). Avantageusement, l'arbre 46 et la couronne 51 du pignon inverseur 45 forment une seule et même pièce, ce qui permet de renforcer la solidité du pignon inverseur 45.On the other hand, the end 32 of the second locking rod 30 has a toothing 36 tangent to the periphery of the follower 14, that is to say that the toothing 36 is tangent to the external circumference 24 of the teeth 27, 28 of the follower 14. This toothing 36 cooperates indirectly with the other part 41 of the thickness of the teeth 27, 28 of the follower 14. This locking rod 30 moves through an opening 42 made in the other end 43 of the housing 2 and slides along the rear face 44 of the headrest 4. There is interposed between the follower 14 and the second locking rod 30 at least one reversing pinion 45 meshing, on the one hand, with the teeth 27, 28 of the follower 14 and , on the other hand, with the toothing 36 of the end 32 of the second locking rod 30. As a result of the presence of this reversing pinion 45, the second locking rod 30 moves in the opposite direction relative to the first locking rod 29. This reversing pinion 45 constitutes the e indirect cooperation means between the follower 14 and the end 32 of the second operating rod 30. According to the invention, this indirect cooperation means is located inside the longitudinal groove practiced in the song of the opening and in which the housing 2 and the locking rods 29, 30 are housed. The reversing pinion 45 comprises a shaft 46, the ends 47, 48 of which are engaged in the bores 49, 50 produced in the walls 8, 9 (see figure 6). Advantageously, the shaft 46 and the crown 51 of the reversing pinion 45 form a single piece, which makes it possible to strengthen the solidity of the pinion. inverter 45.

Pour obtenir une meilleure transmission entre le fouillot 14 et la seconde tringle de verrouillage 30, on confère à l'extrémité 32 de cette seconde tringle de verrouillage 30 une longueur telle que la denture 36 peut coopérer avec deux pignons inverseurs 45 et 52. Ces pignons inverseurs 45, 52 sont identiques et disposés de part et d'autre du fouillot 14.To obtain better transmission between the follower 14 and the second locking rod 30, the end 32 of this second locking rod 30 is given a length such that the toothing 36 can cooperate with two reversing pinions 45 and 52. These pinions inverters 45, 52 are identical and arranged on either side of the follower 14.

Pour augmenter la fiabilité de la crémone à larder 1, on a intérêt d'augmenter le diamètre des pignons inverseurs 45, 52.To increase the reliability of the cremone bolt 1, it is advantageous to increase the diameter of the reversing pinions 45, 52.

Selon le premier mode d'exécution (voir essentiellement les figures 1 et 2), on confère à la têtière 4, sur approximativement la longueur du boîtier 2, une partie déportée 53, ce qui permet d'augmenter la place disponible entre la face arrière 44 de la têtière 4 et le corps 15 du fouillot 14. L'épaisseur 54 de cette partie 53, déportée dans un plan parallèle à l'ensemble de la têtière 4, a une valeur inférieure au jeu de feuillure de la fenêtre, porte ou analogue.According to the first embodiment (see essentially FIGS. 1 and 2), the faceplate 4 is given, over approximately the length of the housing 2, a remote part 53, which makes it possible to increase the space available between the rear face 44 of the headrest 4 and the body 15 of the follower 14. The thickness 54 of this part 53, offset in a plane parallel to the assembly of the headrest 4, has a value less than the clearance of the rebate of the window, door or similar.

De même, l'extrémité 32 de la seconde tringle de verrouillage 30 comporte une partie déportée 55 parallèle à la partie déportée 53 de la têtière 4.Likewise, the end 32 of the second locking rod 30 comprises a remote part 55 parallel to the remote part 53 of the headrest 4.

Selon le second mode d'exécution (voir essentiellement les figures 3 à 7), on augmente encore davantage la place disponible pour le ou les pignons inverseurs 45, 52 et les tringles de verrouillage 29,-30. Pour obtenir ce résultat, chaque partie 5, 6 du boîtier 2 comporte un retour 401, 402 permettant d'obtenir deux logements 56, 57. Dans ces logements 56, 57 sont engagées les extrémités 58, 59 de deux tronçons de têtière 4" 42. Les retours 401, 402 des deux parties 5, 6 du boîtier 2 s'étendent sur toute la longueur du boîtier 2. Cette longueur est supérieure à l'espace séparant les extrémités 58, 59 des deux tronçons de têtière 4" 42 de sorte que les retours 401, 402 . recouvrent selon une certaine longueur les extrémités 58, 59 des deux tronçons de têtière 41, 42, Ainsi, dans ce second mode d'exécution, la têtière unique 4 est remplacée par deux tronçons de têtière 41, 42. De ce fait, la têtière est supprimée entre les emplacements de fixation du boîtier 2 sur la têtière 4. Les deux extrémités 31, 32 des deux tringles de verrouillage 29, 30 coulissent sur la face interne 60, 61 des retours 40" 402 des deux parties 5, 6 du boîtier 2, étant entendu que l'épaisseur de ces deux retours 401, 402 est nettement inférieure à l'épaisseur de la têtière 4.According to the second embodiment (see essentially FIGS. 3 to 7), the space available for the reverse gear (s) 45, 52 and the locking rods 29, -30 is further increased. To obtain this result, each part 5, 6 of the housing 2 has a return 40 1 , 40 2 making it possible to obtain two housings 56, 57. In these housings 56, 57 are engaged the ends 58, 59 of two sections of headrest 4 "4 2. The returns 40 1 , 40 2 of the two parts 5, 6 of the housing 2 extend over the entire length of the housing 2. This length is greater than the space separating the ends 58, 59 of the two sections of headrest 4 "4 2 so that returns 40 1 , 40 2 . cover the ends 58, 59 of the two sections of headrest 4 1 , 4 2 over a certain length. Thus, in this second embodiment, the single headrest 4 is replaced by two sections of headrest 4 1 , 4 2 . Therefore, the headrest is removed between the fixing locations of the housing 2 on the headrest 4. The two ends 31, 32 of the two locking rods 29, 30 slide on the internal face 60, 61 returns 40 "40 2 two parts 5, 6 of the housing 2, it being understood that the thickness of these two returns 40 1 , 40 2 is significantly less than the thickness of the headrest 4.
