Description

L'invention concerne une crémone, en particulier une crémone-serrure pour porte, porte-fenêtre ou analogue comportant un mécanisme de commande solidaire de l'ouvrant comprenant un fouillot permettant la manoeuvre d'au moins une tringle de manoeuvre pourvue d'au moins un élément de verrouillage pénétrant dans une gâche solidaire du dormant; des moyens de rappel élastique permettant de faire passer la tringle de manoeuvre de la position déverrouillée à la position verrouillée; et un élément de blocage permettant le maintien de la tringle de manoeuvre en position déverrouillée, ledit élément de blocage étant rappelé élastiquement dans la position assurant le maintien en position déverrouillée de la tringle de manoeuvre, ledit élément de blocage étant apte à faire saillie sur le chant de l'ouvrant et à coopérer . avec des moyens de déblocage solidaires du dormant.The invention relates to a cremone bolt, in particular a cremone bolt for a door, a French window or the like comprising a control mechanism integral with the opening comprising a nut allowing the operation of at least one operating rod provided with at least a locking element penetrating a keeper integral with the frame; elastic return means making it possible to move the operating rod from the unlocked position to the locked position; and a blocking element enabling the operating rod to be held in the unlocked position, said blocking element being resiliently returned to the position ensuring the holding in the unlocked position of the operating rod, said blocking element being capable of projecting from the sash song and to cooperate. with unlocking means integral with the frame.

On connaît déjà, par le document DE-B-1.062.143, une crémone-serrure du type ci-dessus énoncé, dont la tringle de commande est automatiquement rappelée en position de verrouillage par l'intermédiaire d'un élément élastique. Pour maintenir ladite tringle de manoeuvre en position de déverrouillage, cette crémone-serrure est pourvue d'un élément de blocage traversant la têtière de la crémone-serrure et faisant saillie par rapport à la face avant de ladite têtière. En fermant l'ouvrant, cet élément de blocage est repoussé et on libère le blocage de la tringle de manoeuvre. Par voie de conséquence, la tringle de manoeuvre est aussitôt rappelée en position de verrouillage.Already known, from document DE-B-1,062,143, a lock-bolt of the type stated above, the control rod of which is automatically returned to the locking position by means of an elastic element. To maintain said operating rod in the unlocked position, this lock lever is provided with a blocking element passing through the headrest of the lock lever and projecting relative to the front face of said headrest. By closing the opening, this blocking element is pushed back and the blocking of the operating rod is released. Consequently, the operating rod is immediately returned to the locked position.

Toutefois, lors de la fermeture de l'ouvrant, l'action exercée sur cet élément de blocage par le moyen de déblocage solidaire du dormant est perpendiculaire à son sens de déplacement. Lorsque l'ouvrant est fermé avec une certaine brutalité, due par exemple à un courant d'air inopiné, il y a risque de déformation de l'élément de blocage. Dans ce cas, la crémone-serrure ne peut plus remplir sa fonction. De même, le sens de déplacement implique que l'élément de blocage est sensible à toute variation du jeu entre ouvrant et dormant. Si, par suite de tolérances de fabrication ou de rétrécissement des matériaux de l'ouvrant ou du dormant, le jeu entre ouvrant et dormant est devenu plus grand que le jeu initialement prévu, le déblocage de la tringle de manoeuvre ne s'opère pas et dans ce cas également la crémone-serrure ne peut plus remplir sa fonction.However, when the opening is closed, the action exerted on this blocking element by the unlocking means secured to the frame is perpendicular to its direction of movement. When the door is closed with a certain brutality, due for example to an unexpected draft, there is a risk of deformation of the blocking element. In this case, the lock-bolt can no longer fulfill its function. Likewise, the direction of movement implies that the blocking element is sensitive to any variation in the clearance between the opening and the standing. If, as a result of manufacturing tolerances or narrowing of the sash or sash materials, the clearance between the sash and the sash has become larger than the clearance initially provided, the release of the operating rod does not take place and in this case also the lock lever can no longer fulfill its function.

On connaît également, par le document US-A-1.387.643, un dispositif de fermeture d'une porte disposé sur les faces arrière de l'ouvrant et du dormant. Ce dispositif comporte une tringle de manoeuvre actionnée par une poignée traversant une lumière réalisée dans l'ouvrant et faisant saillie par rapport à la face avant dudit ouvrant. Cette tringle de manoeuvre comporte une bride dont le chant inférieur présente une partie saillante par rapport au chant de la tringle de manoeuvre. Cette partie saillante coopère avec l'extrémité supérieure d'un élément de blocage élastique solidaire de l'ouvrant lorsque la tringle de manœuvre est en position de déverrouillage. Sur sa face arrière, le cadre dormant comporte en tant que moyen de déblocage une butée ayant la forme d'une patte qui, lors de la fermeture de la porte, repousse l'élément élastique en l'appliquant frontalement contre l'une des faces de l'ouvrant pour supprimer la coopération entre ledit élément élastique et la bride de la tringle de manoeuvre libérant cette dernière. Cette butée fait saillie latéralement par rapport au chant du dormant.Also known, from document US-A-1,387,643, is a device for closing a door disposed on the rear faces of the leaf and of the frame. This device comprises an operating rod actuated by a handle passing through a lumen produced in the opening and projecting relative to the front face of said opening. This operating rod has a flange, the lower edge of which has a protruding part relative to the edge of the operating rod. This projecting part cooperates with the upper end of an elastic blocking element integral with the opening when the operating rod is in the unlocked position. On its rear face, the sleeping frame includes as a release means a stop having the shape of a tab which, when the door is closed, pushes the elastic element by applying it frontally against one of the faces of the opening to remove the cooperation between said elastic element and the flange of the operating rod releasing the latter. This stop protrudes laterally from the edge of the frame.

Toutefois, les différents éléments constituant ce dispositif de verrouillage ne forment ni un ensemble monobloc pouvant se poser en une seule opération dans l'ouvrant, ni une ferrure entaillable à partir du chant de l'ouvrant telle qu'une crémone ou crémone-serrure. De plus, tout cintrage de l'ouvrant provoqué par exemple par un chauffage intérieur et un froid hivernal extérieur risque d'éloigner l'élément élastique de blocage de la butée située derrière ledit élément élastique. Dès que cet éloignement est supérieur à l'action que peut exercer sur ledit élément de blocage le moyen de déblocage solidaire du dormant, le dispositif de fermeture ne peut plus remplir sa fonction.However, the various elements constituting this locking device form neither a one-piece assembly which can be posed in a single operation in the opening, nor a notchable fitting from the edge of the opening such as a cremone bolt or cremone bolt. In addition, any bending of the opening caused for example by interior heating and exterior winter cold risks moving the elastic blocking element away from the stop located behind said elastic element. As soon as this distance is greater than the action that can be exerted on said blocking element the unlocking means secured to the frame, the closing device can no longer fulfill its function.

La présente invention a pour but de remédier à ces inconvénients. L'invention, telle qu'elle est caractérisée dans les revendications, résout ces problèmes en créant une crémone-serrure présentant un élément de blocage repoussé par des moyens de déblocage solidaires du dormant dans un sens parallèle à la direction de l'action exercée sur lui par des moyens de déblocage solidaires du dormant.The present invention aims to remedy these drawbacks. The invention, as characterized in the claims, solves these problems by creating a locking lever having a blocking element pushed back by unlocking means integral with the frame in a direction parallel to the direction of the action exerted on him by unlocking means integral with the frame.

Les avantages obtenus grâce à l'invention consistent essentiellement en ce que l'élément de blocage, du fait qu'il se déplace transversalement par rapport au chant de l'ouvrant et parallèlement à l'action exercée sur lui par les moyens de déblocage solidaires du dormant, n'est ni soumis à des poussées perpendiculaires, ni sensible aux variations du jeu entre ouvrant et dormant. Toute variation du jeu entre ouvrant et dormant entraîne uniquement un contact plus ou moins large entre l'élément de blocage et les moyens de déblocage solidaires du dormant. Elle ne fait plus varier la longueur de la course de l'élément de blocage suscitée par les moyens de déblocage solidaires du dormant.The advantages obtained thanks to the invention essentially consist in that the blocking element, owing to the fact that it moves transversely relative to the edge of the opening leaf and parallel to the action exerted on it by the integral unlocking means of the frame, is neither subjected to perpendicular thrusts, nor sensitive to variations in the clearance between the opening and the frame. Any variation in the clearance between the opening and the frame only causes more or less wide contact between the locking element and the unlocking means secured to the frame. It no longer varies the length of the travel of the blocking element caused by the unlocking means integral with the frame.

On se réfère aux fig. 1 et 2.We refer to fig. 1 and 2.

La crémone-serrure 1 comporte un boîtier 2 constitué de deux plaques parallèles 3, 4 (voir fig. 4) renfermant les différentes pièces constituant le mécanisme 5 et provoquant le déplacement d'au moins une tringle de manoeuvre 6.The lock-bolt 1 comprises a box 2 made up of two parallel plates 3, 4 (see fig. 4) containing the various parts constituting the mechanism 5 and causing the displacement of at least one operating rod 6.

Le mécanisme 5 comporte un fouillot 7 présentant un carré de manoeuvre 8 dans lequel est engagé l'axe d'une poignée de manoeuvre (non représentée). Le fouillot 7 est pourvu d'un doigt 9 muni d'un téton 10 sur lequel prend appui l'extrémité 11 d'un élément élastique 12 tel qu'une lame de ressort dont l'autre extrémité 13 s'enroule en forme de spirale autour d'un axe 14. En actionnant la poignée, on provoque une rotation du fouillot 7 et le téton 10 sollicite l'élément élastique 12 en poussant l'extrémité 11. En relâchant la poignée, l'élément élastique 12 repousse le téton 10 et provoque une rotation du fouillot 7 en sens inverse. De ce fait, la poignée revient automatiquement en position de repos. Le rappel élastique du fouillot en position de repos ainsi que les moyens (non représentés) permettant d'amener et de maintenir la tringle de manoeuvre en position verrouillée font l'objet de la demande initiale 0029405 déposée le 7 novembre 1980.The mechanism 5 comprises a follower 7 having an operating square 8 in which is engaged the axis of an operating handle (not shown). The follower 7 is provided with a finger 9 provided with a stud 10 on which the end 11 bears on an elastic element 12 such as a spring leaf whose other end 13 is wound in the form of a spiral around an axis 14. By actuating the handle, the follower 7 is rotated and the stud 10 urges the elastic element 12 by pushing the end 11. By releasing the handle, the elastic element 12 pushes back the stud 10 and causes rotation of the follower 7 in the opposite direction. As a result, the handle automatically returns to the rest position. The elastic return of the follower to the rest position as well as the means (not shown) making it possible to bring and maintain the operating rod in the locked position are the subject of the initial application 0029405 filed on November 7, 1980.

Le fouillot 7 comporte également un second doigt de dommande 15. Celui-ci agit, en phase de déverrouillage, sur un axe 16 solidaire d'un talon 17 de la tringle de manoeuvre 6. Les extrémités 18, 19 de cet axe 16, soumis à un déplacement vertical, se déplacent dans des lumières verticales 20 pratiquées dans les deux plaques parallèles 3,4 du boîtier 2. Le talon 17 présente à ses extrémités supérieure 21 et inférieure 22 un téton 23, 24 s'engageant dans des trous 25, 26 réalisés dans la tringle de manoeuvre 6, ce qui assure la liaison entre la tringle de manoeuvre 6 et le talon 17. Ce dernier comporte une denture 27 coopérant avec un dispositif 28 de rappel automatique en position de verrouillage de la tringle de manoeuvre 6.The follower 7 also includes a second damage finger 15. This acts, in the unlocking phase, on an axis 16 secured to a heel 17 of the operating rod 6. The ends 18, 19 of this axis 16, subjected when moving vertically, move in vertical slots 20 made in the two parallel plates 3, 4 of the housing 2. The heel 17 has at its upper 21 and lower 22 ends a stud 23, 24 engaging in holes 25, 26 made in the operating rod 6, which ensures the connection between the operating rod 6 and the heel 17. The latter has a toothing 27 cooperating with a device 28 for automatically returning the operating rod 6 to the locking position.

Ce dispositif 28 comporte un flasque 29 dont le chant 30 est pourvu d'une denture 31 coopérant avec la denture 27 du talon 17. Ce flasque 29 pivote autour d'un axe fixe 32 traversé transversalement par l'une des extrémités 33 d'un ressort en spirale 34 dont l'autre extrémité 35 vient s'accrocher à une butée 36 solidaire du flasque 29. Lors de l'action sur le fouillot 7, la tringle de manoeuvre 6, coulissant derrière une têtière de recouvrement et de guidage 37, provoque, par la coopération des dentures 27 et 31, la rotation du flasque 29 et, de ce fait, la compression du ressort en spirale 34.This device 28 comprises a flange 29 whose edge 30 is provided with a toothing 31 cooperating with the toothing 27 of the heel 17. This flange 29 pivots about a fixed axis 32 traversed transversely by one of the ends 33 of a spiral spring 34, the other end 35 of which hangs on a stop 36 integral with the flange 29. During the action on the follower 7, the operating rod 6, sliding behind a cover and guide faceplate 37, causes, by the cooperation of the teeth 27 and 31, the rotation of the flange 29 and, therefore, the compression of the spiral spring 34.

Pendant l'ouverture de l'ouvrant, la tringle de manoeuvre 6 doit être maintenue en position de déverrouillage. A cet effet, on prévoit un ensemble 38. Cet ensemble 38 se compose d'un élément de blocage 39 comportant deux branches perpendiculaires 40,41 présentant une section d'une croix. Une des branches 40 est parallèle à la face avant 42 de la têtière 37. L'extrémité arrière 43 de l'autre branche 41 vient se loger dans une lumière 44 pratiquée dans le talon 17 et elle est maintenue dans cette lumière 44 par l'extrémité 45, 46 de deux éléments élastiques 47, 48 dont l'autre extrémité 49, 50 est fixée par des éléments de fixation 51, 52 sur les faces internes 53, 54 des plaques parallèles 3 et 4 (voirfig. 4). La branche 40 se déplace transversalement par rapport à la face avant 42 de la têtière 37 dans une coulisse 55 et elle est maintenue par deux griffes 56, 57 coiffant les extrémités supérieure 58 et inférieure 59 de la branche 40. L'extrémité avant 60 de la branche 41, faisant saillie par rapport à la face avant 42 de la têtière 37, se déplace latéralement entre le chant inférieur 61 de la griffe supérieure 56 et le chant supérieur 62 de la griffe inférieure 57 (voir fig. 3). Pour assurer le verrouillage automatique de la crémone-serrure et, par voie de conséquence, de la porte ou porte-fenêtre lors de la fermeture de l'ouvrant, il est nécessaire de dégager l'extrémité arrière 43 de la branche 41 de l'élément de blocage 39 de la lumière 44 du talon 17. On l'obtient en poussant latéralement sur l'extrémité avant 60 de cette même branche 41. Il en résulte un déplacement de l'extrémité 45, 46 du ressort 47, 48 qui traverse une lumière 63, 64 réalisée dans les plaques parallèles 3, 4 (voir fig. 4 et 6).During the opening of the opening, the operating rod 6 must be kept in the unlocked position. To this end, an assembly 38 is provided. This assembly 38 consists of a locking element 39 comprising two perpendicular branches 40, 41 having a cross section. One of the arms 40 is parallel to the front face 42 of the headrest 37. The rear end 43 of the other arm 41 is housed in a hole 44 made in the heel 17 and it is held in this hole 44 by the end 45, 46 of two elastic elements 47, 48, the other end 49, 50 of which is fixed by fastening elements 51, 52 on the internal faces 53, 54 of the parallel plates 3 and 4 (see fig. 4). The branch 40 moves transversely relative to the front face 42 of the headrest 37 in a slide 55 and it is held by two claws 56, 57 covering the upper 58 and lower 59 ends of the branch 40. The front end 60 of the branch 41, projecting relative to the front face 42 of the headrest 37, moves laterally between the lower edge 61 of the upper claw 56 and the upper edge 62 of the lower claw 57 (see fig. 3). To ensure automatic locking of the bolt lock and, consequently, of the door or French window when the opening is closed, it is necessary to release the rear end 43 of the branch 41 of the blocking element 39 of the light 44 of the heel 17. It is obtained by pushing laterally on the front end 60 of this same branch 41. This results in a displacement of the end 45, 46 of the spring 47, 48 which passes through a light 63, 64 produced in the parallel plates 3, 4 (see fig. 4 and 6).

Pour provoquer ce déplacement latéral, on prévoit des moyens de déblocage 65 solidaires du chant du dormant. Ces moyens de déblocage 65 comportent une butée 66 dont la face 67 coopère avec la face latérale 68 de l'extrémité avant 60 de la branche 41 de l'élément de blocage 39. Cette butée 66 est disposée entre deux évidements 69, 70 dans lesquels viennent se loger les griffes 56, 57. La pénétration de ces griffes 56, 57 est limitée par les fonds 71, 72 de ces évidements 69, 70.To cause this lateral movement, release means 65 are provided which are integral with the edge of the frame. These unlocking means 65 comprise a stop 66 whose face 67 cooperates with the lateral face 68 of the front end 60 of the branch 41 of the locking element 39. This stop 66 is disposed between two recesses 69, 70 in which the claws 56, 57 are housed. The penetration of these claws 56, 57 is limited by the bottoms 71, 72 of these recesses 69, 70.

Lors de la fermeture de l'ouvrant, le fonctionnement de la crémone-serrure, conforme à l'invention, est le suivant:

  • La face 67 de la butée 66 des moyens de déblocage 65 repousse latéralement l'extrémité avant 60 de la branche 41 et, par voie de conséquence, l'élément de blocage 39 coulisse dans la coulisse 55 sollicitant le ressort 48. De ce fait, on dégage l'extrémité arrière 43 de la branche 41 de l'élément de blocage 39 de la lumière 44 du talon 17. Le ressort en spirale 34 se détend et fait pivoter le flasque 29. La denture 31 du flasque 29 entraîne la denture 27 du talon 17 et il y a déplacement automatique de la tringle 6 depuis sa position de déverrouillage à sa position de verrouillage (voir fig. 5 à 7).
When the opening is closed, the operation of the locking lever, in accordance with the invention, is as follows:
  • The face 67 of the stop 66 of the unlocking means 65 laterally pushes the front end 60 of the branch 41 and, consequently, the locking element 39 slides in the slide 55 biasing the spring 48. As a result, the rear end 43 of the branch 41 of the blocking element 39 of the light 44 of the heel is released. The spiral spring 34 relaxes and makes the flange 29 pivot. The toothing 31 of the flange 29 drives the toothing 27 of the heel 17 and there is automatic displacement of the rod 6 from its unlocking position to its locking position (see fig. 5 to 7).
