Description

L'invention concerne une ferrure de fenêtre, porte-fenêtre ou analogue comportant un dispositif de sécurité empêchant une fausse manoeuvre de la ferrure pendant l'ouverture de l'ouvrant de la fenêtre, porte-fenêtre ou analogue, la ferrure comprenant au moins une tringle de manoeuvre coulissant derrière une têtière logée en feuillure et fixée sur au moins un des montants et/ou traverses de l'ouvrant, le dispositif de sécurité, comprenant un élément de blocage à rappel élastique se déplaçant transversalement pour bloquer la tringle de manoeuvre et dont la tête fait saillie par rapport à la face externe de la têtière.The invention relates to a window fitting, French window or the like comprising a safety device preventing a false operation of the fitting during the opening of the window opening, French window or the like, the fitting comprising at least one operating rod sliding behind a headrest housed in the rebate and fixed on at least one of the uprights and / or cross members of the opening, the safety device, comprising a blocking element with elastic return moving transversely to block the operating rod and whose head protrudes from the outer face of the headrest.

Ces ferrures comprennent une tringle de manoeuvre actionnée par une poignée située sur le montant ou la traverse du côté de l'ouverture de l'ouvrant. La tringle de manoeuvre, logée généralement dans une rainure réalisée dans le chant de l'ouvrant, est recouverte d'une têtière. Elle se déplace en translation longitudinale et actionne des éléments de verrouillage coopérant avec des gâches solidaires du dormant. Si l'on actionne la poignée par mégarde pendant l'ouverture de l'ouvrant, les éléments de verrouillage se déplacent en position de fermeture et on risque leur détérioration ainsi que celle des gâches. Si les ferrures sont conçues pour ouvrants oscillo-battants, la tringle de manoeuvre actionne en plus, par l'intermédiaire d'un ou de deux renvois d'angle, des éléments de ferrure situés sur une traverse ou sur l'autre montant de l'ouvrant. Pour passer la poignée de la position d'ouverture "à la française" à la position d'ouverture "à soufflet", il est nécessaire de fermer au préalable l'ouvrant. Sinon, on risque de déclencher une fausse manoeuvre provoquant la mise en "drapeau" de l'ouvrant. Sa remise en place est d'autant plus incommode que les dimensions et le poids de l'ouvrant sont importants.These fittings include an operating rod actuated by a handle located on the upright or cross member on the side of the opening of the opening. The operating rod, generally housed in a groove made in the edge of the opening, is covered with a headrest. It moves in longitudinal translation and actuates locking elements cooperating with strikes secured to the frame. If the handle is accidentally actuated during the opening of the door, the locking elements move to the closed position and there is a risk of their deterioration and that of the strikes. If the fittings are designed for tilt-and-turn windows, the operating rod also actuates, by means of one or two angular gearboxes, hardware elements located on a cross member or on the other upright of the opening. To pass the handle from the "French" open position to the "bellows" open position, it is necessary to close the sash beforehand. Otherwise, there is a risk of triggering a false maneuver causing the opening of the "flag". Its replacement is all the more inconvenient as the dimensions and the weight of the opening are important.

Il était donc nécessaire de prévoir un dispositif de sécurité devant prévenir toute fausse manoeuvre de la ferrure en position d'ouverture de l'ouvrant.It was therefore necessary to provide a safety device to prevent any false operation of the fitting in the opening position of the opening.

Ainsi, on connaît, par le document DE-A-2 918 274, un dispositif de sécurité confomre au précunbule del la revendication 1 empêchant la translation de la tringle de manoeuvre lorsque la fenêtre est ouverte. Ce dispositif de sécurité comporte un élément de blocage à rappel élastique dont la tête est saillante par rapport à la face externe de la têtière. Cette tête coopère avec une butée de déverrouillage présentant dans un plan horizontal deux rampes inclinées, cette butée étant solidaire du chant du dormant. L'élément de blocage présente une embase prenant appui contre un élément élastique, l'ensemble étant logé dans un boîtier inséré dans une entaille pratiquée dans le fond de la rainure dans laquelle se déplace la tringle de manoeuvre, le boîtier étant solidaire de la face interne de la têtière. A l'emplacement de l'élément de blocage, la tringle de manoeuvre coulisse entre la têtière et le boîtier et comporte une lumière longitudinale pour le passage de l'élément de blocage. Ce dernier traverse un orifice pratiqué dans la têtière pour rejoindre sa tête saillante. Sur la face inférieure de la tringle de manoeuvre est fixée une plaque comportant également une lumière longitudinale. La plaque comporte sur sa face interne des épaulements entre lesquels s'engage l'embase de l'élément de blocage. Cette embase est reliée à la tête par un étranglement dont l'épaisseur est légèrement inférieure à la largeur des lumières longitudinales.Thus, from document DE-A-2 918 274, a safety device is known as the preamble of claim 1 preventing the translation of the operating rod when the window is open. This safety device comprises a blocking element with elastic return, the head of which projects from the external face of the headrest. This head cooperates with an unlocking stop having in a horizontal plane two inclined ramps, this stop being integral with the edge of the frame. The locking element has a base bearing against an elastic element, the assembly being housed in a housing inserted in a notch made in the bottom of the groove in which the operating rod moves, the housing being integral with the face internal faceplate. At the location of the locking element, the operating rod slides between the headrest and the housing and has a longitudinal opening for the passage of the locking element. The latter crosses an opening made in the headrest to reach its protruding head. On the underside of the operating rod is fixed a plate also comprising a longitudinal lumen. The plate has on its internal face shoulders between which engages the base of the blocking element. This base is connected to the head by a constriction whose thickness is slightly less than the width of the longitudinal slots.

Lorsque l'ouvrant est ouvert, l'élément élastique repousse l'élément de blocage, de sorte que l'embase vient s'insérer entre les épaulements en prenant appui contre la face interne de la plaque. Il est alors impossible de manoeuvrer la ferrure. En fermant l'ouvrant, la tête de l'élément de blocage glisse le long de la rampe inclinée de la butée de déverrouillage et l'élément de blocage est repoussé dans le boîtier en comprimant l'élément élastique. L'embase se désengage des épaulements et il devient possible d'actionner la tringle de manoeuvre.When the door is open, the elastic element pushes the blocking element, so that the base is inserted between the shoulders by pressing against the internal face of the plate. It is then impossible to operate the fitting. By closing the opening, the head of the blocking element slides along the inclined ramp of the unlocking stop and the blocking element is pushed back into the housing by compressing the elastic element. The base disengages from the shoulders and it becomes possible to actuate the operating rod.

Cependant, ce dispositif de sécurité présente plusieurs inconvénients. La hauteur saillante de l'élément de blocage est constante. Or, il arrive que le jeu entre le chant de l'ouvrant et le chant du dormant soit variable. De ce fait, il y a, soit -la dissolution de la coopération entre l'élément de blocage et la butée de déverrouillage, soit le contact entre ces deux éléments ne se fait pas correctement et on risque de détériorer la tête de l'élément de blocage. Par ailleurs, il faut prévoir un entaillage supplémentaire dans le fond de la rainure dans laquelle se déplace la tringle de manoeuvre. Ceci crée un affaiblissement du montant au droit de cette entaille. Finalement, l'entaille doit être réalisée avant la pose de la ferrure.However, this security device has several drawbacks. The protruding height of the locking element is constant. However, it sometimes happens that the clearance between the song of the opening and the song of the frame is variable. As a result, there is either the dissolution of the cooperation between the blocking element and the unlocking stop, or the contact between these two elements is not made correctly and there is a risk of damaging the head of the element. blocking. In addition, it is necessary to provide an additional notching in the bottom of the groove in which the operating rod moves. This creates a weakening of the amount at the right of this notch. Finally, the notch must be made before fitting the hardware.

La présente invention a pour but de remédier à ces inconvénients et se propose de fournir une ferrure comportant un dispositif de sécurité dont le résultat recherché est identique à celui des dispositifs de sécurité connus mais de conception totalement différente permettant d'obtenir un certain nombre d'avantages techniques cités ci-après. L'invention, telle qu'elle est caractérisée dans les revendications, résout le problème consistant à créer une ferrure de fenêtre, porte- fenêtre ou analogue pourvue d'un dispositif de sécurité comportant un clapet de déverrouillage faisant saillie par rapport à la face externe de la têtière et articulé sur un axe situé du côté du dormant, ce clapet de déverrouillage, parallèle au plan médian de la têtière, étant tenu appliqué contre la tête de l'élément de blocage par un élément élastique.The present invention aims to remedy these drawbacks and proposes to provide a fitting comprising a safety device whose desired result is identical to that of known safety devices but of totally different design making it possible to obtain a certain number of technical advantages mentioned below. The invention, as characterized in the claims, solves the problem of creating a window fitting, French window or the like provided with a safety device comprising an unlocking valve projecting from the external face of the headrest and articulated on an axis located on the side of the frame, this unlocking valve, parallel to the median plane of the headrest, being held applied against the head of the blocking element by an elastic element.

Les avantages obtenus grâce à la présente invention consistent essentiellement en ce que la conception particulière de la partie saillante de l'élément de blocage permet de loger le dispositif de sécurité dans le jeu normal existant entre l'ouvrant et le dormant.The advantages obtained thanks to the present invention essentially consist in that the particular design of the projecting part of the blocking element makes it possible to accommodate the safety device in the existing normal play. between the sash and the frame.

Par ailleurs, on augmente la fiabilité de ce dispositif de sécurité du fait que le dormant n'appuie plus perpendiculairement sur la tête de l'élément de blocage mais qu'il agit de biais sur un clapet de déverrouillage qui, lui, transmet l'action quasi longitudinalement sur l'élément de blocage.Furthermore, the reliability of this safety device is increased by the fact that the frame no longer presses perpendicularly on the head of the blocking element but that it acts at an angle on an unlocking valve which, in turn, transmits the almost longitudinally acting on the locking element.

De plus, en raison de la conception compacte du dispositif de sécurité un entaillage supplémentaire est évité. Ceci permet non seulement de réduire les opérations de fabrication mais également de pourvoir les ferrures déjà mises en place du dispositif de sécurité en utilisant la rainure réalisée dans le chant de l'ouvrant pour la translation de la tringle de manoeuvre.In addition, due to the compact design of the safety device, additional nicking is avoided. This allows not only to reduce manufacturing operations but also to provide the fittings already in place of the safety device by using the groove made in the edge of the opening for the translation of the operating rod.

Finalement, du fait que le boîtier et le clapet de déverrouillage sont amovibles, on confère au dispositif de sécurité la possibilité de la réversibilité avant pose, ce qui permet une utilisation droite et/ou gauche dudit dispositif de sécurité.Finally, because the housing and the release valve are removable, the safety device is given the possibility of reversibility before installation, which allows right and / or left use of said safety device.

Conformément à l'invention, la ferrure de fenêtre, porte-fenêtre ou analogue comprend un dispositif de sécurité 1 destiné à interdire toute fausse manoeuvre de la ferrure d'une fenêtre, particulièrement celle d'une fenêtre s'ouvrant sélectivement autour d'un axe horizontal ou vertical au moyen d'une poignée de manoeuvre unique non représentée assurant, soit la fermeture de la fenêtre, soit l'ouverture "à la française", soit l'ouverture "à soufflet" de l'ouvrant 2, tel que décrit dans l'exemple ci-après.According to the invention, the window fitting, French window or the like comprises a safety device 1 intended to prevent any false operation of the fitting of a window, particularly that of a window opening selectively around a horizontal or vertical axis by means of a single operating handle, not shown, ensuring either the closing of the window, or the "French-style" opening, or the "bellows" opening of the opening 2, such as described in the example below.

On réalise dans le chant 3 de l'ouvrant 2 une rainure 4 permettant le logement de la ferrure et la translation d'une tringle de manoeuvre 5 assurant les trois positions de l'ouvrant 2. Cette tringle de manoeuvre se déplace derrière la face interne 6 d'une têtière 7 logée dans une seconde rainure 8 superposée à la rainure 4.A groove 4 is formed in the edge 3 of the opening 2 allowing the fitting of the fitting and the translation of an operating rod 5 ensuring the three positions of the opening 2. This operating rod moves behind the internal face 6 of a headrest 7 housed in a second groove 8 superimposed on the groove 4.

A un emplacement donné, de préférence à proximité de la poignée de manoeuvre, la ferrure comporte le dispositif de sécurité 1 dont un des composants coopère soit directement avec le chant 9 du dormant 10, soit avec une butée fixée à cet endroit. Seule la coopération entre ces deux éléments permet d'actionner la tringle de manoeuvre 5.At a given location, preferably close to the operating handle, the fitting comprises the safety device 1, one of the components of which cooperates either directly with the edge 9 of the frame 10, or with a stop fixed at this location. Only the cooperation between these two elements makes it possible to actuate the operating rod 5.

Selon l'invention, le dispositif de sécurité 1 comporte un ensemble compact 11 composé d'une partie interne 111 formée essentiellement d'un boîtier 12 logé dans la rainure 4 et d'un élément de blocage 13 coopérant avec la tringle de manoeuvre 5 et d'une partie externe 112 constituant le clapet de déverrouillage 14 qui, par suite de l'action du chant 9 du dormant 10 ou d'une butée fixée sur, ou entaillée dans le chant 9 du dormant 10, provoque la dissolution de la coopération de l'élément de blocage 13 avec la tringle de manoeuvre 5. Cette partie externe 112 située entre le chant 3 de l'ouvrant 2 et le chant 9 du dormant 10, est appliquée sur la face extèrne 15 de la têtière 7.According to the invention, the safety device 1 comprises a compact assembly 11 composed of an internal part 11 1 essentially formed by a housing 12 housed in the groove 4 and by a blocking element 13 cooperating with the operating rod 5 and of an external part 11 2 constituting the unlocking valve 14 which, as a result of the action of the edge 9 of the frame 10 or of a stop fixed on, or notched in the edge 9 of the frame 10, causes the dissolution of the cooperation of the locking element 13 with the operating rod 5. This external part 11 2 located between the edge 3 of the opening 2 and the edge 9 of the frame 10, is applied to the outer face 15 of the headrest 7 .

On se réfère à la figure 4.We refer to figure 4.

On pratique dans la tringle de manoeuvre 5 au droit du dispositif de sécurité 1 une lumière 16 traversée par l'ensemble compact 11. Cette lumière 16 comporte trois zones de positionnement la première concerne la position d'ouverture "à soufflet", la seconde se rapporte à l'ouverture "à la française" et la troisième à la position fermée de l'ouvrant 2. La lumière 16 est ainsi constituée d'une première partie oblongue 17, dont l'axe longitudinal est situé dans le plan médian 18 de la tringle de manoeuvre 5, qui concerne la position d'ouverture "à soufflet". L'une des extrémités 19 de cette première partie oblongue 17 est obturée alors que l'autre extrémité 20 aboute à une seconde partie oblongue 21 à travers laquelle passe l'élément de fixation 22 de la têtière 7 (voir figure 2). La seconde partie oblongue 21 concerne la position fermée de l'ouvrant 2. Les deux parties oblongues 17 et 21 sont situées dans le prolongement l'une de l'autre. La largeur 23 de la seconde partie oblongue 21 est supérieure à la largeur 24 de la première partie oblongue 17. On pratique dans cette dernière une entrée de gâche 25 dont la largeur 26 est de préférence identique à la largeur 23 de la seconde partie oblongue 21. De ce fait, on obtient deux paires d'épaulement 27, 28, 29, 30 servant d'arrêt à l'élément de blocage 13 et empêchant la tringle de manoeuvre 5 de coulisser lorsque la fenêtre est en position d'ouverture. De ce fait, ces épaulements 27, 28, 29, 30 constituent un des moyens de blocage de la tringle de manoeuvre 5. L'entrée de gâche 25 concerne la position d'ouverture "à la française" de l'ouvrant 2.There is a light 16 through the compact assembly 11 in the operating rod 5 in line with the safety device 1. This light 16 has three positioning zones the first relates to the "bellows" open position, the second relates to the "French" opening and the third to the closed position of the opening 2. The lumen 16 thus consists of a first oblong portion 17, the longitudinal axis of which is located in the median plane 18 of the operating rod 5, which relates to the "bellows" opening position. One of the ends 19 of this first oblong part 17 is closed while the other end 20 leads to a second oblong part 21 through which the fixing element 22 of the headrest 7 passes (see FIG. 2). The second oblong part 21 relates to the closed position of the opening 2. The two oblong parts 17 and 21 are located in the extension of one another. The width 23 of the second oblong part 21 is greater than the width 24 of the first oblong part 17. A door entry 25 is made in the latter, the width 26 of which is preferably identical to the width 23 of the second oblong part 21 As a result, two pairs of shoulders 27, 28, 29, 30 are obtained serving as a stop for the locking element 13 and preventing the operating rod 5 from sliding when the window is in position. opening hours. As a result, these shoulders 27, 28, 29, 30 constitute one of the means for blocking the operating rod 5. The keeper entry 25 relates to the "French" opening position of the opening 2.

Selon l'invention, la distance séparant deux zones de positionnement consécutives est égale à la course de translation de la tringle de manoeuvre 5 nécessaire à la modification de la position de l'ouvrant 2, à savoir fenêtre verrouillée, ouverture "à la française" ou ouverture "à soufflet".According to the invention, the distance separating two consecutive positioning zones is equal to the travel of translation of the operating rod 5 necessary for the modification of the position of the leaf 2, namely locked window, "French" opening or "bellows" opening.

On se réfère à la figure 5.We refer to figure 5.

A l'emplacement du dispositif de sécurité 1, la têtière 7 comporte un trou 31 pour le passage de l'élément de blocage 13. On pratique dans la têtiêre 7, à égale distance de part et d'autre du trou 31, deux orifices 32, 33 permettant le passâge des moyens d'assemblage du boîtier 12 et du clapet de déverrouillage 14 Le trou 31 et les deux orifices 32, 33 sont disposés dans un même alignement et sont situés sur le plan médian 34 de la têtière 7.At the location of the safety device 1, the headrest 7 has a hole 31 for the passage of the blocking element 13. There are two holes in the headrest 7, at equal distance on either side of the hole 31 32, 33 allowing the passage of the assembly means of the housing 12 and the unlocking valve 14 The hole 31 and the two orifices 32, 33 are arranged in the same alignment and are located on the median plane 34 of the headrest 7.

On se réfère aux figures 6, 7 et 8.We refer to Figures 6, 7 and 8.

Le boîtier 12 comporte une embase 35 dont la face arrière 36 vient s'appliquer contre le fond 37 de la rainure 4. Une des extrémités 38 de l'embase 35 fait saillie par rapport au chant transversal 39 du corps du boîtier 12. Dans cette extrémité 38 est réalisé un orifice 41 permettant le passage de l'élément de fixation 22 de la têtière 7. De ce fait, la ferrure est maintenue en position au droit du boîtier 12. Le corps 40 est séparé de l'embase 35 par une rainure 42 réalisée dans les deux chants transversaux 39, 43 et un bord longitudinal 44 du corps 40. Cette rainure 42 sert de logement à un élément de fixation 45 ayant la forme d'un "U" et qui assure la liaison entre le boîtier 12 et le clapet de déverrouillage 14 (voir également figures 2 et 12), cet élément de fixation 45 étant élastique.The housing 12 has a base 35, the rear face 36 of which rests against the bottom 37 of the groove 4. One of the ends 38 of the base 35 projects relative to the transverse edge 39 of the body of the housing 12. In this end 38 is made an orifice 41 allowing the passage of the fixing element 22 of the headrest 7. As a result, the fitting is held in position in line with the housing 12. The body 40 is separated from the base 35 by a groove 42 produced in the two transverse edges 39, 43 and a longitudinal edge 44 of the body 40. This groove 42 serves as a housing for a fastening element 45 having the shape of a "U" and which ensures the connection between the housing 12 and the unlocking valve 14 (see also FIGS. 2 and 12), this fixing element 45 being elastic.

La face supérieure 46 du corps 40 comporte quatre bossages longitudinaux 47, 48, 49, 50 entre lesquels coulisse la tringle de manoeuvre 5 qui est guidée latéralement par cesdits bossages 47, 48, 49, 50.The upper face 46 of the body 40 has four longitudinal bosses 47, 48, 49, 50 between which slides the operating rod 5 which is guided laterally by these said bosses 47, 48, 49, 50.

Pour assurer un certain jeu entre la tringle de manoeuvre 5 et la têtière 7, cette face supérieure 46 comporte des butées saillantes 51, 52, 53 venant prendre appui contre la face interne 6 de la têtière 7. La hauteur de ces butées saillantes 51, 52, 53 est légèrement supérieure à l'épaisseur de la tringle de manoeuvre 5. On pratique à travers le corps 40 et l'embase 35 deux orifices 54, 55, se trouvant, lorsque le dispositif de sécurité 1 est monté, dans le prolongement des orifices 32, 33 de la têtière 7 et servant de passages aux moyens d'assemblage du boîtier 12 et du clapet de déverrouillage 14. Dans ces orifices 54, débouche la rainure 42.To ensure a certain clearance between the operating rod 5 and the headrest 7, this upper face 46 has projecting stops 51, 52, 53 coming to bear against the internal face 6 of the headrest 7. The height of these projecting stops 51, 52, 53 is slightly greater than the thickness of the operating rod 5. It is practiced through the body 40 and the base 35 two orifices 54, 55, being, when the safety device 1 is mounted, in the extension orifices 32, 33 of the headrest 7 and serving as passages for the means of assembling the housing 12 and the unlocking valve 14. In these orifices 54, the groove 42 opens.

Deux de ces butées saillantes 52, 53 servent de guide à l'élément de blocage 13. On se réfère maintenant aux figures 2, 6, 7 et 8. L'élément de blocage 13 est logé dans un orifice 56 réalisé dans le corps du boîtier 2. Cet orifice 56 sert également de logement à un élément élastique 57 exerçant une poussée sur l'élément de blocage 13 pour assurer à ce dernier une position saillante, donnant au clapet de déverrouillage une position inclinée par rapport à la face externe 15 de la têtière 7.Two of these projecting stops 52, 53 serve as a guide for the blocking element 13. Reference is now made to FIGS. 2, 6, 7 and 8. The blocking element 13 is housed in an orifice 56 made in the body of the housing 2. This orifice 56 also serves as a housing for an elastic element 57 exerting a pressure on the blocking element 13 to ensure that the latter a protruding position, giving the unlocking valve an inclined position relative to the external face 15 of the headrest 7.

L'élément de blocage 13 se compose d'un corps rectangulaire 58 constituant le second moyen de blocage de la tringle de manoeuvre 5, ce corps rectangulaire 58 comportant une largeur 59 correspondant à la largeur 26 de l'entrée de gâche 25 réalisée dans la première partie oblongue 17 de la tringle de manoeuvre 5. La course de l'élément de blocage 13 à l'intérieur de l'orifice 56 est telle que ce corps rectangulaire 58 s'escamote entièrement dans ledit orifice 56. Ce corps rectangulaire 58 est surmonté d'un embout cylindrique 60 dont le diamètre est légèrement inférieur au diamètre du trou 31 de la têtière 7. On réalise dans cet embout cylindrique 60 un trou taraudé 61 dans lequel est vissée l'extrémité filetée 62 d'une vis 63 pourvue d'une tête 64 s'inscrivant dans un cercle de diamètre identique à celui de l'embout cylindrique 60 et présentant à sa partie supérieure 65 un moyen de prise 66 pour un outil.The blocking element 13 consists of a rectangular body 58 constituting the second blocking means of the operating rod 5, this rectangular body 58 having a width 59 corresponding to the width 26 of the strike entry 25 made in the first oblong part 17 of the operating rod 5. The stroke of the blocking element 13 inside the orifice 56 is such that this rectangular body 58 retracts entirely into said orifice 56. This rectangular body 58 is surmounted by a cylindrical end-piece 60 whose diameter is slightly less than the diameter of the hole 31 in the headrest 7. In this cylindrical end-piece 60 a tapped hole 61 is made in which the threaded end 62 is screwed with a screw 63 provided with 'A head 64 forming part of a circle of diameter identical to that of the cylindrical tip 60 and having at its upper part 65 a gripping means 66 for a tool.

Ainsi, on obtient un élément de blocage réglable en modifiant la position de la vis 63 par rapport à l'embout cylindrique 60. De ce fait, on peut modifier la partie saillante de l'élément de blocage 13 par rapport à la face externe 15 de la têtière 7, en fonction du jeu existant entre le chant 3 de l'ouvrant 2 et le chant 9 du dormant 10.Thus, an adjustable blocking element is obtained by modifying the position of the screw 63 relative to the cylindrical end piece 60. As a result, the protruding part of the blocking element 13 can be modified relative to the external face 15 of the headrest 7, as a function of the clearance existing between the edge 3 of the opening leaf 2 and the edge 9 of the frame 10.

Après mise en place de l'élément de blocage 13 dans l'orifice 56 du boîtier 12, on procède à un sertissage dans la surface 67 des butées saillantes 52, 53 pour obtenir des arrêts 68, 69. Ceux-ci évitent une perte des pièces 13 et 57 lors du retournement du dispositif 1 dans un sens inverse.After the locking element 13 has been placed in the orifice 56 of the housing 12, a protrusion is made in the surface 67 of the protruding stops 52, 53 to obtain stops 68, 69. These prevent loss of the parts 13 and 57 when the device 1 is turned in the opposite direction.

On se réfère aux figures 9 à 11.We refer to Figures 9 to 11.

Le clapet de déverrouillage 14 comporte avantageusement un support 70 qui, lors de l'assemblage du dispositif de sécurité 1, vient prendre appui contre la face externe 15 de la têtière 7. Dans ce support 70 est pratiqué un trou 71 pour le passage de la tête ronde 64 de l'élément de blocage 13. On procède dans ce support 70 à une découpe 72 permettant d'obtenir deux ailes parallèles 73, 74. Entre ces deux ailes 73, 74 est disposé un volet mobile 75 pivotant autour d'un axe d'articulation 76 dont les extrémités 77, 78 sont engagées dans des trous 79, 80 réalisés dans les deux ailes parallèles 73, 74. Sur cet axe d'articulation 76 est enfilé un élément élastique 81 dont une des extrémités 82 est engagée dans un trou 83 réalisé dans une des ailes parallèles 73 alors que l'autre extrémité 84 est enfoncée dans un trou 85 réalisé dans le chant 86 d'une découpe 87 pratiquée dans le volet mobile 75. Le support 70 surmonté du volet mobile 75 constituant le clapet de déverrouillage 14 comporte une épaisseur d'une valeur légèrement inférieure au jeu existant entre le chant 3 de l'ouvrant 2 et le chant 9 du dormant 10.The unlocking valve 14 advantageously comprises a support 70 which, during the assembly of the safety device 1, comes to bear against the external face 15 of the faceplate 7. In this support 70 a hole 71 is made for the passage of the round head 64 of the locking element 13. A cutout 72 is made in this support 70 making it possible to obtain two parallel wings 73, 74. Between these two wings 73, 74 is disposed a movable flap 75 pivoting around a hinge pin 76, the ends 77, 78 of which are engaged in holes 79, 80 made in the two parallel wings 73, 74. On this hinge pin 76 is threaded an elastic element 81, one of the ends 82 of which is engaged in a hole 83 made in one of the parallel wings 73 while the other end 84 is pressed into a hole 85 made in the edge 86 of a cut 87 made in the movable flap 75. The support 70 surmounted by the movable flap 75 constituting the release valve 14 includes a e thickness of a value slightly less than the clearance existing between edge 3 of the opening 2 and edge 9 of the frame 10.

Lorsque l'élément de blocage 13 est en position escamotée, l'élément élastique 81 appliquant le volet mobile 75 en direction de la face extérieure 88 du support 70, la face extérieure 89 dudit volet mobile 75 déborde la têtière 7 d'une valeur égale au jeu entre les chants 3 et 9. Le jeu mini est atteint lorsque le volet mobile 75 est à fleur avec le dessus 90 des ailes parallèles 73, 74.When the locking element 13 is in the retracted position, the elastic element 81 applying the movable flap 75 in the direction of the outer face 88 of the support 70, the outer face 89 of said movable flap 75 extends over the headrest 7 by an equal value to the clearance between the edges 3 and 9. The minimum clearance is reached when the movable flap 75 is flush with the top 90 of the parallel wings 73, 74.

La face interne 91 du support 70 comporte deux ergots de fixation 92, 93 traversant successivement les orifices 32, 33 de la têtière 7, les lumières oblongues 17, 21 de la tringle de manoeuvre 5 et les orifices 54, 55 du boîtier 12. Ces ergots de fixation 92, 93 présentent une rainure 94, 95 dans laquelle s'engagent les ailes 96, 97 de l'élément de fixation 45 (voir figure 12).The internal face 91 of the support 70 comprises two fixing lugs 92, 93 successively passing through the orifices 32, 33 of the headrest 7, the oblong slots 17, 21 of the operating rod 5 and the orifices 54, 55 of the housing 12. These fixing lugs 92, 93 have a groove 94, 95 in which the wings 96, 97 of the fixing element 45 engage (see FIG. 12).

Le montage du dispositif de sécurité 1 est le suivant on dispose dans la rainure 42 l'élément de fixation 45. Puis, on applique la face supérieure 46 du boîtier 12 contre la face interne de la tringle de manoeuvre 5 de sorte que cette dernière vient se placer entre les quatre bossages longitudinaux 47, 48, 49, 50 et que la tête 64 et l'embout cylindrique 60 traversent l'entrée de gâche 25 de la tringle de manoeuvre et le trou 31 de la têtière 7. Puis, on introduit depuis la face externe 15 de la têtière 7 les ergots de fixation 92, 93 du clapet de déverrouillage 14. Après leur passage à travers les orifices 32, 33 de la têtière 7, les deux ergots de fixation 92, 93 sont introduits dans les orifices 54, 55 du boîtier 12. Ces deux ergots de fixation 92, 93 écartent les deux ailes 96, 97 de l'élément de fixation 45 jusqu'à ce que les rainures 94, 95 se trouvent en face des deux ailes 96, 97. En raison de l'élasticité de l'élément de fixation 45, ces deux dernières viennent s'encliqueter dans les rainures 94, 95 et, de ce fait, les deux éléments boîtier 12, et clapet de déverrouillage 14 sont assemblés et, par voie de conséquence, le dispositif de sécurité 1 est solidaire de la têtière 7.The mounting of the safety device 1 is as follows, the fixing element 45 is placed in the groove 42. Then, the upper face 46 of the housing 12 is applied against the internal face of the operating rod 5 so that the latter comes be placed between the four longitudinal bosses 47, 48, 49, 50 and that the head 64 and the cylindrical endpiece 60 pass through the striker inlet 25 of the operating rod and the hole 31 of the headrest 7. Then, we introduce from the external face 15 of the headrest 7 the fixing lugs 92, 93 of the unlocking valve 14. After their passage through the orifices 32, 33 of the headrest 7, the two fixing lugs 92, 93 are introduced into the orifices 54, 55 of the housing 12. These two fixing lugs 92, 93 separate the two wings 96, 97 from the fixing element 45 until the grooves 94, 95 are opposite the two wings 96, 97. Due to the elasticity of the fastening element 45, the latter two snap into place. in the grooves 94, 95 and, as a result, the two elements housing 12, and release valve 14 are assembled and, consequently, the safety device 1 is secured to the headrest 7.

Le fonctionnement du dispositif de sécurité 1 est le suivant:

  • - On considère que la fenêtre est fermée et la ferrure en position verrouillée le corps rectangulaire 58 de l'élément de blocage 13 est situé face à la seconde partie oblongue 21 de la lumière 16 de la tringle de manoeuvre 5. Le volet mobile 75 du clapet de déverrouillage 14 a poussé l'élément de blocage 13 en position inactive.
The operation of the safety device 1 is as follows:
  • - It is considered that the window is closed and the fitting in the locked position the rectangular body 58 of the locking element 13 is located opposite the second oblong part 21 of the lumen 16 of the operating rod 5. The movable flap 75 of the unlocking valve 14 has pushed the locking element 13 into the inactive position.

On actionne la tringle de manoeuvre 5 pour permettre l'ouverture "à la française" de la fenêtre. A la fin de la translation de la tringle de manoeuvre 5, le corps rectangulaire 58, coulissant en face de la seconde partie oblongue 21, est placé en face de l'entrée de gâche 25 de la tringle de manoeuvre 5.The operating rod 5 is actuated to allow the "French" opening of the window. At the end of the translation of the operating rod 5, the rectangular body 58, sliding in front of the second oblong part 21, is placed opposite the striker inlet 25 of the operating rod 5.

En ouvrant la fenêtre, l'élément élastique 57 précontraint dans l'orifice 56 du corps 40 du boîtier 12 se détend en faisant saillir l'élément de blocage 13. Le corps rectangulaire 58 vient se placer dans l'entrée de gâche entre les épaulements 27, 28, 29, 30. Simultanément, l'embout cylindrique 60 pourvu de la vis 63 saillit du trou 71 du support et pousse le volet mobile 75. Celui-ci pivote autour de l'axe d'articulation 76 en provoquant la compression de l'élément élastique 81. De ce fait, le volet mobile 75 forme un angle avec le support 70 appliqué contre la face externe 15 de la têtière 7. La valeur de l'angle est variable en fonction de la position de la vis 63 dans le trou taraudé 61 de l'embout cylindrique 60. Il y a lieu de noter que l'axe d'articulation 76 est situé du côté du dormant 10. Du fait que le corps rectangulaire 58 de l'élément de blocage 13, est emprisonné entre les épaulements 27, 28, 29, 30, la manipulation de la tringle de manoeuvre 5 est rendue impossible. L'élément élastique 81 tient lé volet mobile 75 contre la face extérieure 88 du support 70 du clapet de déverrouillage 14.When opening the window, the elastic element 57 prestressed in the orifice 56 of the body 40 of the housing 12 relaxes by projecting the locking element 13. The rectangular body 58 comes to be placed in the strike entry between the shoulders 27, 28, 29, 30. Simultaneously, the cylindrical endpiece 60 provided with the screw 63 protrudes from the hole 71 of the support and pushes the movable flap 75. The latter pivots around the articulation axis 76 causing the compression of the elastic element 81. As a result, the movable flap 75 forms an angle with the support 70 applied against the external face 15 of the headrest 7. The value of the angle is variable depending on the position of the screw 63 in the threaded hole 61 of the cylindrical endpiece 60. It should be noted that the hinge pin 76 is located on the side of the frame 10. Because the rectangular body 58 of the locking element 13, is trapped between the shoulders 27, 28, 29, 30, the manipulation of the operating rod 5 is made impossible. The elastic element 81 holds the movable flap 75 against the external face 88 of the support 70 of the unlocking valve 14.

En fermant la fenêtre, le coin du dormant 10 entre en contact avec la face extérieure 89 du volet mobile 75 du clapet de déverrouillage 14. Ce contact se fait plus ou moins près de l'axe d'articulation 76 en fonction, d'une part, de l'angle d'ouverture conféré au volet mobile 75 par l'élément de blocage 13, et, d'autre part, du jeu existant entre le chant 9 du dormant 10 et le chant 3 de l'ouvrant 2. Au cours du glissement du coin du dormant 10 sur le volet mobile 75, ledit coin exerce une poussée sur le volet mobile 75. Ce dernier transmet cette poussée sur la tête 64 de la vis 63 et, par voie de conséquence, sur l'embout 60 et le corps rectangulaire 58 de l'élément de blocage 13. Au cours de cette poussée, on dissout la coopération entre le corps rectangulaire 58 et les épaulements 27, 28, 29, 30 de l'entrée de gâche 25 de la tringle de manoeuvre 5 en comprimant l'élément élastique 57. Le corps rectangulaire 58 est escamoté à l'intérieur de l'orifice 56.By closing the window, the corner of the frame 10 comes into contact with the outer face 89 of the movable flap 75 of the unlocking valve 14. This contact is made more or less near the hinge pin 76 depending on a on the one hand, the opening angle given to the movable flap 75 by the blocking element 13, and, on the other hand, the clearance existing between the edge 9 of the frame 10 and the edge 3 of the opening 2. At during the sliding of the corner of the frame 10 on the movable flap 75, said corner exerts a push on the movable flap 75. The latter transmits this push on the head 64 of the screw 63 and, consequently, on the end piece 60 and the rectangular body 58 of the locking element 13. During this thrust, the cooperation between the rectangular body 58 and the shoulders 27, 28, 29, 30 of the strike plate entry 25 of the operating rod is dissolved. 5 by compressing the elastic element 57. The rectangular body 58 is retracted inside the orifice 56.

De ce fait, il devient possible de provoquer la translation de la tringle de manoeuvre 5 soit pour verrouiller la fenêtre, soit de disposer cette dernière en position d'ouverture "à soufflet".As a result, it becomes possible to cause the translation of the operating rod 5 either to lock the window, or to have the latter in the "bellows" open position.

Dans ce dernier cas, les butées saillantes 51, 52, 53 du boîtier 12 et l'embout cylindrique 60 de l'élément de condamnation coulissent dans la première partie oblongue 17 de la tringle de manoeuvre 5.In the latter case, the projecting stops 51, 52, 53 of the housing 12 and the cylindrical end piece 60 of the locking element slide in the first oblong part 17 of the operating rod 5.
