Description

L'invention concerne une ferrure de verrouillage pour porte, fenêtre ou analogue, à ouvrant coulissant, composée :
- d'une embase fixée en applique sur le montant avant de l'ouvrant ;
- d'une poignée mobile en rotation munie d'un organe de verrouillage destiné à coopérer avec un gâche ou équivalent solidaire du dormant ;
- de moyens de rappel élastique en position de verrouillage de la poignée mobile ;
- et d'un dispositif de blocage de cette dernière en position déverrouillée.The invention relates to a locking fitting for a door, window or the like, with a sliding leaf, comprising:
- a fixed base applied on the front upright of the opening;
- a handle movable in rotation provided with a locking member intended to cooperate with a keeper or equivalent integral with the frame;
- elastic return means in the locking position of the movable handle;
- And a locking device for the latter in the unlocked position.

La présente invention concerne l'industrie spécialisée dans le domaine de la quincaillerie du bâtiment.The present invention relates to the industry specialized in the field of building hardware.

On connaît déjà par le document EP-A-0.067.075 une ferrure de verrouillage correspondant à la description ci-dessus. Ainsi, cette ferrure de verrouillage se compose d'une embase montée, en applique, sur le montant avant d'un ouvrant coulissant. Cette embase supporte une poignée mobile en rotation autour d'un axe vertical comportant un organe de verrouillage destiné à coopérer avec une gâche solidaire du dormant.Document EP-A-0.067.075 already knows a locking fitting corresponding to the above description. Thus, this locking fitting consists of a base mounted, on the surface, on the front upright of a sliding leaf. This base supports a handle movable in rotation about a vertical axis comprising a locking member intended to cooperate with a keeper secured to the frame.

Plus précisément, l'embase se présente sous forme d'une cornière à angle obtus comportant, dans l'angle intérieur, une rainure verticale destinée à coopérer avec un bourrelet hémicylindrique solidaire de la poignée mobile. Cette dernière est, plus particulièrement, formée par une aile radiale comportant, sur l'un de ses chants verticaux, ledit bourrelet hémicylindrique et, sur le chant vertical opposé, une aile circonférentielle, disposée coaxialement à l'axe de pivotement de la poignée et constituant l'organe de préhension et de commande de cette dernière. Quant à l'organe de verrouillage, il est fixé sur l'aile radiale précitée et comporte, à son extrémité libre, un bec susceptible d'entrer en liaison avec une gâche en forme de crochet disposée sur le dormant. Cette ferrure de verrouillage est également munie de moyens de rappel élastique en position de verrouillage de la poignée mobile. Ces moyens sont constitués, plus particulièrement, par un ressort hélicoïdal précontraint disposé entre l'aile radiale de ladite poignée mobile et l'une des ailes de la cornière formant l'embase. Ainsi, pour commander l'ouverture de la porte ou fenêtre coulissante, l'usager exerce une pression sur l'élément de préhension, décrit ci-dessus, de manière à provoquer le pivotement de la poignée mobile et comprimer le ressort hélicoïdal des moyens de rappel élastique, Il en résulte le désengagement de l'organe de verrouillage de la gâche correspondante et la possibilité de commander le coulissement de l'ouvrant.More specifically, the base is in the form of an obtuse angle angle comprising, in the interior corner, a vertical groove intended to cooperate with a semi-cylindrical bead secured to the movable handle. The latter is, more particularly, formed by a radial wing comprising, on one of its vertical edges, said semi-cylindrical flange and, on the opposite vertical edge, a circumferential wing, arranged coaxially with the axis of pivoting of the handle and constituting the gripping and control member thereof. As for the locking member, it is fixed to the above-mentioned radial wing and comprises, at its free end, a spout capable of coming into contact with a hook-shaped keeper disposed on the frame. This locking fitting is also provided with elastic return means in the locking position of the movable handle. These means consist, more particularly, of a prestressed helical spring disposed between the radial wing of said movable handle and one of the wings of the angle iron forming the base. Thus, to control the opening of the sliding door or window, the user exerts a pressure on the gripping element, described above, so as to cause the pivoting of the movable handle and compress the helical spring of the means of elastic return, This results in the disengagement of the locking member of the corresponding strike and the possibility of controlling the sliding of the opening.

En raison des moyens de rappel élastique, le relâchement de l'action de l'usager sur la poignée mobile provoque le retour, automatique, de cette dernière en position de blocage. De ce fait, l'usager venant de sortir de l'habitation, en franchissant le vantail ouvert, peut-être condamné à rester à l'extérieur, suite à une manipulation intempestive de l'ouvrant exécutée, par exemple, par un enfant. En effet, le simple fait de refermer l'ouvrant coulissant provoque, systématiquement, le verrouillage de ce dernier contre le dormant en raison desdits moyens de rappel élastique en position de verrouillage de la poignée mobile.Due to the elastic return means, the relaxation of the action of the user on the movable handle causes the automatic return of the latter to the locked position. Therefore, the user coming out of the house, crossing the open leaf, may be condemned to stay outside, following untimely manipulation of the opening performed, for example, by a child. Indeed, the simple fact of closing the sliding leaf causes, systematically, the locking of the latter against the frame because of said elastic return means in the locking position of the movable handle.

Pour éviter de tels incidents, la ferrure de verrouillage, connue et décrite dans le document antérieur cité ci-dessus, comporte, en outre, un dispositif de blocage de la poignée mobile en position déverrouillée. Ce dispositif se compose, d'une part, d'une rainure, de section ovale, accueillant le bourrelet hémicylindrique de la poignée mobile, rainure autorisant un jeu radial de cette dernière par rapport à son axe de pivotement. D'autre part, il est prévu, sur le chant vertical de l'aile saillante de la cornière constituant l'embase, une cavité susceptible d'accueillir un bossage aménagé au niveau de la face inférieure de l'aile circonférentielle formant l'élément de préhension.To avoid such incidents, the locking fitting, known and described in the prior document cited above, further comprises a device for locking the movable handle in the unlocked position. This device consists, on the one hand, a groove, of oval section, receiving the semi-cylindrical bead of the movable handle, groove allowing a radial clearance of the latter relative to its pivot axis. On the other hand, there is provided, on the vertical edge of the projecting wing of the angle iron constituting the base, a cavity capable of accommodating a boss arranged at the level of the underside of the circumferential wing forming the element. gripping.

Le dispositif de blocage est complété par les moyens de rappel élastique en position de verrouillage ayant, également, une action radiale susceptible de provoquer le déplacement transversal de la poignée mobile par rapport à son axe de pivotement et, finalement, d'assurer l'engagement du bossage précité dans la cavité correspondante pour maintenir ladite poignée en position déverrouillée. Cette configuration impose l'intervention d'un usager pour libérer, à nouveau, la poignée mobile, celle-ci reprenant sa position verrouillée sous l'action des moyens de rappel élastique.The locking device is completed by the elastic return means in the locking position having, also, a radial action capable of causing the transverse displacement of the movable handle relative to its pivot axis and, ultimately, ensuring engagement of the aforementioned boss in the corresponding cavity to maintain said handle in the unlocked position. This configuration requires the intervention of a user to release, again, the movable handle, the latter returning to its locked position under the action of the elastic return means.

L'avantage certain que procure ce type de ferrure de verrouillage semi-automatique consiste en une sécurité accrue. En effet, les manoeuvres intempestives de l'ouvrant coulissant sont normalement, sans conséquence sur le verrouillage et le déverrouillage de ce dernier.The clear advantage of this type of semi-automatic locking fitting is increased security. Indeed, untimely maneuvers of the sliding leaf are normally, without consequence on the locking and unlocking of the latter.

Toutefois, ces ferrures de verrouillage présentent un certain nombre d'inconvénients dus, essentiellement, à leur conception particulièrement complexe nécessitant l'utilisation de pièces spécifiques, non standard.However, these locking fittings have a certain number of drawbacks due, essentially, to their particularly complex design requiring the use of specific, non-standard parts.

Il en est ainsi des moyens de rappel élastique, à action radiale, agissant sur la poignée mobile, d'une part, pour ramener cette dernière, constamment, en position verrouillée et, d'autre part, pour conférer à ladite poignée mobile un déplacement transversal à son axe de pivotement. Ces moyens de rappel élastique, en raison de leur particularité, nécessitent, pour leur conception, un outillage et la programmation d'une fabrication spécifique. Ceci a pour conséquence d'augmenter, sensiblement, le prix de revient global de ce type de ferrure de verrouillage connu.This is the case with elastic return means, with radial action, acting on the movable handle, on the one hand, to bring the latter, constantly, into the locked position and, on the other hand, to give said movable handle displacement transverse to its pivot axis. These means elastic return, due to their particularity, require, for their design, tools and programming of a specific manufacturing. This has the effect of significantly increasing the overall cost price of this type of known locking fitting.

D'autre part, le dispositif de blocage mis en oeuvre s'avère peu fiable et totalement inefficace en cas de fatigue des moyens de rappel élastique. En effet, on constate que, seule l'action radiale de ces moyens de rappel élastique assure le blocage de la poignée mobile en position déverrouillée. Cependant, ces mêmes moyens de rappel élastique exercent, simultanément, une pression sur ladite poignée ayant tendance à provoquer le désengagement du bossage situé sur cette dernière, de sa cavité aménagée sur l'embase, cette action étant, de ce fait, totalement, antagoniste à la précédente. En conséquence, il est nécessaire de trouver un parfait compromis entre le coefficient de raideur dans le sens axial de ces moyens de rappel élastique et leur coefficient de raideur radiale pour assurer un bon fonctionnement du dispositif de blocage tout en autorisant une commande qui soit plus ou moins aisée de la poignée mobile.On the other hand, the blocking device used proves to be unreliable and totally ineffective in the event of fatigue of the elastic return means. Indeed, it is found that only the radial action of these elastic return means ensures the locking of the movable handle in the unlocked position. However, these same elastic return means simultaneously exert pressure on said handle, which tends to cause the boss located on the latter to disengage from its cavity arranged on the base, this action therefore being totally antagonistic. to the previous one. Consequently, it is necessary to find a perfect compromise between the coefficient of stiffness in the axial direction of these elastic return means and their coefficient of radial stiffness to ensure proper operation of the locking device while authorizing a control which is more or less easy of the movable handle.

En considérant qu'un tel compromis puisse être atteint dans la théorie, cela paraît tout à fait difficile dans le cadre de la réalité. En effet, il est possible qu'une manoeuvre intempestive, même commandée par un enfant, provoque l'entrechoquement de l'ouvrant contre le dormant. Ceci peut avoir pour conséquence de libérer, à nouveau, le pivotement de la poignée mobile, amenant cette dernière en position verrouillée et, finalement, en coopération avec la gâche disposée sur le dormant. Dans ce cas, on est dans une situation identique à celle évoquée plus haut, sans qu'aucune autre solution de secours ne soit proposée à l'usager, isolé à l'extérieur de l'habitation, pour pénétrer à nouveau à l'intérieur de cette dernière.Considering that such a compromise can be reached in theory, this seems quite difficult in the context of reality. Indeed, it is possible that an untimely maneuver, even commanded by a child, causes the door leaf to collide against the frame. This may have the consequence of releasing, again, the pivoting of the movable handle, bringing the latter into the locked position and, finally, in cooperation with the keeper disposed on the frame. In this case, we are in a situation identical to that mentioned above, without any other backup solution being offered to the user, isolated outside the house, to enter it again.

La présente invention a pour but de remédier aux inconvénients précités. L'invention telle qu'elle est caractérisée dans les revendications résout le problème consistant à créer une ferrure de verrouillage, pour porte, fenêtre ou analogue, à ouvrant coulissant, composée :
- d'une embase fixée en applique sur le montant avant de l'ouvrant ;
- d'une poignée mobile en rotation munie d'un organe de verrouillage destiné à coopérer avec une gâche ou équivalent solidaire du dormant ;
- de moyens de rappel élastique en position de verrouillage de la poignée mobile
- et d'un dispositif de blocage de cette dernière en position déverrouillée, ce dispositif de blocage étant constitué de moyens permettant de décaler l'axe de pivotement de la poignée mobile en cours de manipulation de la ferrure de verrouillage pour modifier le sens de rotation de ladite poignée mobile sous l'action des moyens de rappel élastique.The object of the present invention is to remedy the aforementioned drawbacks. The invention as characterized in the claims solves the problem of creating a locking fitting, for a door, window or the like, with a sliding leaf, comprising:
- a fixed base applied on the front upright of the opening;
- a handle movable in rotation provided with a locking member intended to cooperate with a keeper or equivalent integral with the frame;
- elastic return means in the locking position of the movable handle
- And a locking device for the latter in the unlocked position, this locking device consisting of means making it possible to offset the pivot axis of the movable handle during manipulation of the locking fitting to modify the direction of rotation of said movable handle under the action of the elastic return means.

Les avantages obtenus grâce à cette invention consistent, essentiellement, en ce que la ferrure de verrouillage comporte un dispositif de blocage de la poignée mobile en position déverrouillée qui est d'une efficacité et d'une fiabilité incontestable contrairement à la ferrure de verrouillage décrite dans le document antérieur. En effet, grâce à ses particularités, il permet de faire en sorte que les moyens de rappel élastique contribuent au maintien de la poignée mobile en position déverrouillée.The advantages obtained thanks to this invention consist, essentially, in that the locking fitting comprises a device for locking the movable handle in the unlocked position which is of undeniable efficiency and reliability unlike the locking fitting described in the previous document. Indeed, thanks to its peculiarities, it makes it possible for the elastic return means to contribute to the maintenance of the movable handle in the unlocked position.

D'autre part, la ferrure de verrouillage 1 est munie d'une poignée mobile 6 montée pivotante sur l'embase 2 et comportant un organe de verrouillage 7 destiné à coopérer avec une gâche 8 solidaire du dormant 9 de ladite porte, fenêtre ou analogue 10. On notera cependant, que, dans certains cas, la gâche est facultative, notamment lorsque la morphologie du profilé formant le montant 11 du dormant 9 autorise la coopération avec un organe de verrouillage 7 solidaire de la poignée mobile 6.On the other hand, the locking fitting 1 is provided with a movable handle 6 pivotally mounted on the base 2 and comprising a locking member 7 intended to cooperate with a keeper 8 integral with the frame 9 of said door, window or the like 10. Note, however, that, in certain cases, the keeper is optional, in particular when the morphology of the profile forming the upright 11 of the frame 9 authorizes cooperation with a locking member 7 secured to the movable handle 6.

Selon un mode de réalisation préférentiel, l'embase 2 est formée par une cornière à angle obtus composée d'une aile 12, venant en applique sur la face interne 3 de l'ouvrant 5, et d'une aile saillante 13. Cette embase 2 comporte, dans l'angle intérieur 14, une rainure verticale 15 dans laquelle est emboîté un bourrelet hémicylindrique 16 constituant un axe de pivotement 17 de la poignée mobile 6.According to a preferred embodiment, the base 2 is formed by an obtuse angle angle composed of a wing 12, applied on the internal face 3 of the opening 5, and a projecting wing 13. This base 2 has, in the interior corner 14, a vertical groove 15 in which is fitted a semi-cylindrical bead 16 constituting a pivot axis 17 of the movable handle 6.

Plus précisément, cette dernière est formée par une aile radiale 18 comportant sur l'un de ses chants verticaux 19 ledit bourrelet hémicylindrique 16. Sur le chant vertical opposé 20, cette aile radiale 18 est munie d'une aile circonférentielle 21 disposée coaxialement à l'axe de pivotement 17 et constituant l'organe de préhension et de commande de la poignée mobile 6.More precisely, the latter is formed by a radial wing 18 comprising on one of its vertical edges 19 said semi-cylindrical flange 16. On the opposite vertical edge 20, this radial wing 18 is provided with a circumferential wing 21 arranged coaxially with the pivot axis 17 and constituting the gripping and control member of the movable handle 6.

Quant à l'organe de verrouillage 7, il est formé par une lame 22 reliée à l'aile radiale 18 et comportant à son extrémité libre 23 un bec 24 destiné à coopérer avec la gâche 8, ou équivalent, présente sur le dormant 9 et ayant une configuration en forme de crochet.As for the locking member 7, it is formed by a blade 22 connected to the radial wing 18 and comprising at its free end 23 a spout 24 intended to cooperate with the keeper 8, or equivalent, present on the frame 9 and having a hook-like configuration.

La ferrure de verrouillage 1 objet de la présente invention, comporte, en outre, des moyens de rappel élastique 25 susceptibles de ramener, systématiquement, la poignée mobile 6 en position de verrouillage. Préférentiellement, ces moyens de rappel élastique 25 sont constitués par un ressort hélicoïdal 26 interposé entre l'aile radiale 18 de la poignée mobile 6 et l'aile saillante 13 de l'embase 2. Le maintien en position de ce ressort hélicoïdal 26 peut être assuré par tout moyen approprié et, notamment, par l'intermédiaire d'éléments en forme de crochets 27 susceptibles de coopérer avec l'une ou l'autre spire 28, 29 situées aux extrémités du ressort hélicoïdal 26.The locking fitting 1 that is the subject of the present invention further comprises elastic return means 25 capable of systematically bringing the movable handle 6 back into the locking position. Preferably, these elastic return means 25 are constituted by a helical spring 26 interposed between the radial wing 18 of the movable handle 6 and the projecting wing 13 of the base 2. The maintenance in position of this helical spring 26 can be provided by any appropriate means and, in particular, by means of hook-shaped elements 27 capable of cooperating with one or the other turn 28, 29 situated at the ends of the helical spring 26.

Cependant, de tels moyens de rappel élastique 25 constituent un inconvénient en cas de manipulation intempestive de l'ouvrant 5. En effet, une telle manipulation, ayant pour conséquence le verrouillage dudit ouvrant 5 peut empêcher un usager, situé à l'extérieur de l'habitation, de pénétrer, à nouveau, dans cette dernière. Dans ce but, la ferrure de verrouillage 1 comporte, également, un dispositif de blocage 30 qui soit en mesure de maintenir la poignée mobile 6 en position déverrouillée. Avantageusement, ce dispositif de blocage 30 peut être actionné par l'intermédiaire de moyens de commande interne 31 et de moyens de commande externe 32.However, such elastic return means 25 constitute a drawback in the event of untimely manipulation of the opening 5. In fact, such manipulation, resulting in the locking of said opening 5, can prevent a user, located outside the 'habitation, to penetrate, again, into the latter. For this purpose, the fitting of Locking 1 also includes a blocking device 30 which is able to keep the movable handle 6 in the unlocked position. Advantageously, this blocking device 30 can be actuated by means of internal control means 31 and external control means 32.

On obtient, ainsi, une double sécurité en cas de mauvaise manipulation de la ferrure de verrouillage 1 ou de l'ouvrant 5. D'une part, les moyens de commande interne 31 du dispositif de blocage 3 garantissent, à l'utilisateur, le maintien en position déverrouillée de la poignée mobile 6. D'autre part, en cas de manipulation intempestive de la ferrure de verrouillage 1 depuis l'intérieur de l'habitation, provoquant le verrouillage dudit ouvrant 5, il est possible à un usager, placé à l'extérieur, de déverrouiller la porte, fenêtre ou analogue 10 et actionner le dispositif de blocage 30 à l'aide des moyens de commande externe 32.This provides double security in the event of improper handling of the locking fitting 1 or of the opening 5. On the one hand, the internal control means 31 of the locking device 3 guarantee, to the user, the holding the movable handle in the unlocked position 6. On the other hand, in the event of untimely manipulation of the locking fitting 1 from inside the dwelling, causing the locking of said opening 5, it is possible for a user, placed outside, to unlock the door, window or the like 10 and actuate the locking device 30 using the external control means 32.

Selon une caractéristique de la présente invention, le dispositif de blocage 30 est constitué par des moyens 33 permettant de décaler l'axe de pivotement 17 de la poignée 6 en cours de manipulation de la ferrure de verrouillage 1 pour, finalement, modifier le sens de rotation de ladite poignée mobile 6 sous l'action des moyens de rappel élastique 25.According to a characteristic of the present invention, the blocking device 30 is constituted by means 33 making it possible to offset the pivot axis 17 of the handle 6 during manipulation of the locking fitting 1 in order, finally, to modify the direction of rotation of said movable handle 6 under the action of the elastic return means 25.

En somme, l'objectif visé par ces moyens 33 consiste à déplacer l'axe de pivotement de la poignée mobile 6 par rapport au centre d'application de la force exercée par le ressort hélicoïdal 26.In short, the objective targeted by these means 33 consists in moving the pivot axis of the movable handle 6 relative to the center of application of the force exerted by the helical spring 26.

Selon un mode de réalisation préférentiel, les moyens 33 sont constitués, d'une part, par une bielle 34 reliant la poignée mobile 6 à l'embase 2, l'axe de cette bielle 34 étant décalé angulairement par rapport au plan de l'aile radiale 18. D'autre part, les moyens 33 sont complétés par une rainure verticale 15 aménagée dans l'embase 2 autorisant une certaine mobilité du bourrelet 16 solidaire de ladite aile radiale 18, notamment, suivant une direction parallèle au plan de l'ouvrant 5.According to a preferred embodiment, the means 33 consist, on the one hand, of a connecting rod 34 connecting the movable handle 6 to the base 2, the axis of this connecting rod 34 being angularly offset relative to the plane of the radial wing 18. On the other hand, the means 33 are completed by a groove vertical 15 arranged in the base 2 allowing a certain mobility of the bead 16 secured to said radial wing 18, in particular, in a direction parallel to the plane of the opening 5.

Plus précisément, en ce qui concerne la bielle 34, celle-ci est reliée à l'embase 2, par une articulation 35 et à proximité du chant arrière 36 de la rainure verticale 15. Cette bielle 34 est fixée, en outre, sur la face arrière 37 de l'aile radiale 18 correspondant à la poignée mobile 6 par des moyens d'articulation 38 situés au-delà du centre d'application de la force exercée par les moyens de rappel élastique 25. Plus exactement, le ressort hélicoïdal 26 vient en applique sur la face arrière 37 de l'aile radiale 18, sensiblement, entre les moyens d'articulation 38 de la bielle 34 et l'axe de pivotement 17 de la poignée mobile 6.More specifically, as regards the connecting rod 34, this is connected to the base 2, by a hinge 35 and near the rear edge 36 of the vertical groove 15. This connecting rod 34 is fixed, moreover, on the rear face 37 of the radial wing 18 corresponding to the movable handle 6 by articulation means 38 situated beyond the center of application of the force exerted by the elastic return means 25. More precisely, the helical spring 26 comes to bear on the rear face 37 of the radial wing 18, substantially, between the articulation means 38 of the connecting rod 34 and the pivot axis 17 of the movable handle 6.

Ainsi, lors de la commande de la ferrure de verrouillage 1, la poignée mobile 6 entame, initialement, une rotation autour de l'axe de pivotement 17, le bourrelet hémicylindrique 16 de l'aile radiale 18 se présentant en butée contre le chant arrière 36 de la rainure verticale 15. Puis au-delà d'un certain angle de rotation, la poignée mobile 6 vient en appui sur la bielle 34 et pivote autour des moyens d'articulation 38. Au cours de cette rotation, le bourrelet hémicylindrique 16 se déplace transversalement dans la rainure verticale 15 jusqu'à atteindre le chant avant 40 de cette dernière.Thus, when ordering the locking fitting 1, the movable handle 6 starts, initially, a rotation about the pivot axis 17, the semi-cylindrical bead 16 of the radial wing 18 being in abutment against the rear edge 36 of the vertical groove 15. Then beyond a certain angle of rotation, the movable handle 6 comes to bear on the connecting rod 34 and pivots around the articulation means 38. During this rotation, the semi-cylindrical bead 16 moves transversely in the vertical groove 15 until it reaches the front edge 40 of the latter.

Ce décalage de l'axe de rotation de la poignée mobile 6 par rapport au ressort hélicoïdal 26 modifie l'action de ce dernier sur ladite poignée mobile 6 repoussant celle-ci selon un sens de rotation inverse au verrouillage. De ce fait, le dispositif de blocage 30 conforme à l'invention, permet d'amener la ferrure de verrouillage 1 dans une position déverrouillée parfaitement stable et seul un usager, placé à l'intérieur de l'habitation, est en mesure de commander le verrouillage de l'ouvrant 5.This offset of the axis of rotation of the movable handle 6 relative to the helical spring 26 modifies the action of the latter on said movable handle 6 pushing the latter in a direction of rotation opposite to locking. Therefore, the locking device 30 according to the invention allows to bring the locking fitting 1 in an unlocked position perfectly stable and only a user, placed at inside the house, is able to control the locking of the door 5.

Préférentiellement, la section de la rainure verticale 15 est de forme convexe de manière à définir deux centres de rotation 41, 42, du bourrelet hémicylindrique 16, ce qui tend à accroître la notion de sécurité telle qu'exposée ci-dessus. En effet, en raison de cette configuration, seule une action manuelle sur la poignée mobile 6 permet de vaincre les contraintes élastiques maintenant cette dernière dans ses positions extrêmes et, plus particulièrement, le bourrelet hémicylindrique 16 au niveau des centres de rotation 41, 42.Preferably, the section of the vertical groove 15 is of convex shape so as to define two centers of rotation 41, 42, of the semi-cylindrical bead 16, which tends to increase the concept of security as set out above. In fact, due to this configuration, only manual action on the movable handle 6 overcomes the elastic stresses maintaining the latter in its extreme positions and, more particularly, the semi-cylindrical bead 16 at the centers of rotation 41, 42.

Selon un mode de réalisation décrit ci-dessus, lors de la commande de verrouillage ou de déverrouillage de la poignée mobile 6, cette dernière exécute une rotation autour des moyens d'articulation 38, la reliant à la bielle 34 tout en venant à se décaler, transversalement, dans la rainure verticale 15.According to an embodiment described above, during the locking or unlocking command of the movable handle 6, the latter performs a rotation around the articulation means 38, connecting it to the connecting rod 34 while coming to shift , transversely, in the vertical groove 15.

Toutefois, il peut être préférable de décomposer ces mouvements de sorte que le déverrouillage de l'ouvrant 5 n'engendre pas, systématiquement, l'intervention du dispositif de blocage 30. Sans compter que, dans le cadre d'une telle disposition une mauvaise manipulation de la ferrure de verrouillage 1 peut amener le bourrelet hémicylindrique 16 à se dégager de sa rainure verticale 15 et mettre, momentanément, hors d'usage la poignée mobile 6.However, it may be preferable to decompose these movements so that the unlocking of the opening 5 does not systematically generate the intervention of the locking device 30. Besides, in the context of such an arrangement poor manipulation of the locking fitting 1 can cause the semi-cylindrical bead 16 to disengage from its vertical groove 15 and put the movable handle 6 temporarily out of use.

A cet effet et selon un second mode de réalisation, on dispose de moyens 43 pour guider et contrôler la course de la poignée mobile 6 lors de sa commande. Ces moyens 43 sont constitués, substantiellement, par au moins un flasque 44, rapporté à l'une et/ou l'autre extrémité, supérieure et inférieure, de l'embase 2 et venant, ainsi, se substituer à la bielle 34 formant, en partie, les moyens 33 permettant de décaler l'axe de pivotement de la poignée mobile 6. Dans ce flasque 44 est aménagée une lumière curviligne 45, disposée concentriquement à l'axe de pivotement 17 de la poignée mobile 6 et dans laquelle est engagée l'extrémité d'une broche 46 rapportée sur la face arrière 37 de l'aile radiale 18.To this end and according to a second embodiment, means 43 are available for guiding and controlling the travel of the movable handle 6 when it is ordered. These means 43 consist, substantially, of at least one flange 44, attached to one and / or the other end, upper and lower, of the base 2 and thus, replacing the connecting rod 34 forming, in part, the means 33 making it possible to offset the pivot axis of the movable handle 6. In this flange 44 is arranged a curvilinear light 45, arranged concentrically with the pivot axis 17 of the movable handle 6 and in which is engaged the end of a pin 46 attached to the rear face 37 of the radial wing 18.

De ce fait, lors de la commande de la ferrure de verrouillage 1, la poignée mobile 6 exécute une première rotation autour de l'axe de pivotement 17 selon un angle déterminé par les dimensions de la lumière curviligne 45. Puis, lorsque la broche 46 vient en butée contre l'extrémité 47 de ladite lumière curviligne 45 la poignée mobile 6 pivote autour de cette broche 46 mettant en oeuvre le dispositif de blocage 30.Therefore, when ordering the locking fitting 1, the movable handle 6 performs a first rotation around the pivot axis 17 at an angle determined by the dimensions of the curvilinear light 45. Then, when the pin 46 abuts against the end 47 of said curvilinear lumen 45 the movable handle 6 pivots around this pin 46 implementing the locking device 30.

Ainsi, les moyens de commande interne 31 du dispositif de blocage 30 sont constitués, substantiellement, par la poignée mobile 6, tandis que les moyens de commande externe 32 se présentent, selon un mode de réalisation préférentiel, sous forme d'un élément à clé 48 actionné depuis l'intérieur de la porte, fenêtre ou analogue 10.Thus, the internal control means 31 of the locking device 30 are constituted, substantially, by the movable handle 6, while the external control means 32 are, according to a preferred embodiment, in the form of a key element 48 operated from inside the door, window or the like 10.

Plus précisément, l'élément à clé 48 est un bloc du sûreté inséré dans un logement 49 aménagé depuis l'extérieur dans le montant avant 4 de l'ouvrant 5. Ce bloc de sûreté actionne, à son extrémité 50, introduite dans ledit logement 49, une pièce de transmission 51 formée par un disque 52 muni d'un doigt de commande excentré 53. Ce dernier évolue sur la piste d'une came 54 formée par un flasque 55 solidaire d'une tige de commande 56 émergeant, perpendiculairement, par rapport, à la face interne 3 du montant 4. Ladite tige de commande 56 traverse de part en part l'aile en applique 12 de l'embase 2 au travers d'une lumière 57 et coopère, au niveau de son extrémité libre 58, avec la lame 22 de l'organe de verrouillage 7.More specifically, the key element 48 is a safety block inserted in a housing 49 arranged from the outside in the front upright 4 of the opening 5. This safety block operates, at its end 50, inserted in said housing 49, a transmission part 51 formed by a disc 52 provided with an eccentric control finger 53. The latter evolves on the track of a cam 54 formed by a flange 55 secured to a control rod 56 emerging perpendicularly, relative to the internal face 3 of the upright 4. Said control rod 56 passes right through the applied wing 12 of the base 2 through a light 57 and cooperates, at its free end 58 , with the blade 22 of the locking member 7.

En raison de cette disposition, la commande du bloc de sûreté provoque la rotation du disque 52. Le doigt de commande excentré 53 vient alors à glisser sur la piste de la came 54 repoussant la tige de commande 56 vers l'intérieur de l'ouvrant 5. L'action de cette tige de commande 56 a pour conséquence, initialement, le déverrouillage de la porte, fenêtre ou analogue 10 et, finalement, la commande du dispositif de blocage 30. Lors de la commande inverse de l'élément à clé 48, ladite tige de commande 56 et le flasque 55 sont rappelés dans leur position initiale au moyen d'un élément élastique 59.Because of this arrangement, the control of the safety block causes the disc 52 to rotate. The eccentric control finger 53 then slides on the track of the cam 54 pushing the control rod 56 towards the interior of the opening 5. The action of this control rod 56 has the consequence, initially, of unlocking the door, window or the like 10 and, finally, the control of the locking device 30. During the reverse control of the key element 48, said control rod 56 and the flange 55 are returned to their initial position by means of an elastic element 59.

Il est bien évident que la ferrure de verrouillage conforme à l'invention apporte un plus incontestable sur le plan de la sécurité dans le cadre de son application à des ouvrants coulissants. Les risques d'une manipulation intempestive sont réduits, voire inexistants et la double commande de déverrouillage de l'ouvrant et du dispositif de blocage de la poignée mobile en position déverrouillée permet de solutionner tout problème susceptible d'intervenir.It is obvious that the locking fitting according to the invention provides an undeniable plus in terms of security in the context of its application to sliding doors. The risks of untimely manipulation are reduced, or even non-existent and the double unlocking control of the opening and of the device for locking the movable handle in the unlocked position makes it possible to solve any problem that may arise.
