Description

L'invention concerne un toquer pour ouvrants coulissants, comportant un pêne à crochet, articulé sur le boîtier du loquet et commandé par un élément de commande le reliant à une poignée de manoeuvre, un élément élastique, rappelant indirectement le pêne à crochet dans sa position de fermeture, des moyens de retenue du pêne à crochet en position de fermeture et un poussoir agissant sur ces derniers au moment de la fermeture de l'ouvrant coulissant pour permettre le rappel du pêne à crochet en position de fermeture par l'élément élastique.The invention relates to a latch for sliding doors, comprising a hook bolt, articulated on the latch housing and controlled by a control element connecting it to an operating handle, an elastic element, indirectly recalling the hook bolt in its position. closing, means for retaining the hook bolt in the closed position and a pusher acting on the latter when the sliding leaf is closed to allow the hook bolt to be returned to the closed position by the elastic element.

Un tel loquet est déjà connu par le document EP-A-0 142 342. Ce loquet comporte un dispositif de blocage manoeuvré par une clé. Par l'intermédiaire de cette dernière, on actionne un pêne à crochet, pivotant autour d'un axe d'articulation solidaire du boîtier, au moyen d'un ensemble de pièces composé d'une biellette reliée à l'une de ses extrémités par un axe d'articulation au pêne à crochet et à l'autre extrémité par un axe d'articulation à l'un des angles d'un élément basculant ayant approximativement 1a forme d'un triangle équilatéral. Cet élément basculant, pivotant autour d'un axe d'articulation solidaire du boîtier et situé à un autre angle de ce triangle équilatéral, est relié par un axe d'articulation situé sur le troisième angle de ce triangle équilatéral, à l'extrémité d'un bras de levier dont l'autre extrémité présente une lumière dans laquelle peut coulisser l'axe de la clé de manoeuvre. Sur ledit axe est montée une came coopérant avec un moyen de retenue pour maintenir le pêne à crochet en position de fermeture. Ce moyen de retenue est une pièce supplémentaire formée par un levier basculant pivotant autour d'un axe solidaire du boîtier. Ce levier basculant mis en position de retenue par un élément élastique, comporte une butée contre laquelle prend appui le chant supérieur du bras de levier.Such a latch is already known from document EP-A-0 142 342. This latch comprises a blocking device operated by a key. By means of the latter, a hook bolt is actuated, pivoting about a hinge pin secured to the housing, by means of a set of parts composed of a connecting rod connected to one of its ends by an axis of articulation with the hook bolt and at the other end by an axis of articulation at one of the angles of a tilting element having approximately the shape of an equilateral triangle. This tilting element, pivoting about an articulation axis integral with the housing and located at another angle of this equilateral triangle, is connected by an articulation axis located on the third angle of this equilateral triangle, at the end d 'a lever arm whose other end has a light in which can slide the axis of the operating key. On said axis is mounted a cam cooperating with a retaining means for holding the hook bolt in the closed position. This retaining means is an additional part formed by a rocking lever pivoting about an axis secured to the housing. This tilting lever placed in the retaining position by an elastic element, comprises a stop against which the upper edge of the lever arm bears.

La présente invention a pour objet de réaliser un loquet du type ci-dessus dans lequel le blocage du pêne à crochet dans sa position de fermeture ne fait pas appel à un dispositif de blocage manoeuvré par une clé. L'invention, telle qu'elle est caractérisée dans la revendication 1, permet de parvenir à cet objet en prévoyant un loquet pour ouvrants coulissants comportant un pêne à crochet articulé sur le boîtier du loquet et commandé par un élément de commande le reliant à une poignée de manoeuvre, un élément élastique rappelant indirectement le pêne à crochet dans sa position de fermeture, des moyens de retenue du pêne à crochet en position de fermeture et un poussoir agissant sur ces derniers au moment de la fermeture de l'ouvrant coulissant pour permettre le rappel du pêne à crochet en position de fermeture par l'élément élastique dont l'élément de commande, agissant sur le pêne à crochet, est logé coulissant dans le boîtier et comporte un moyen des moyens de retenue solidaire de l'élément de commande coopérant avec l'autre moyen des moyens de retenue solidaire du pêne à crochet en position de fermeture et qu'une liaison entre l'élément de commande et le pêne à crochet comporte une course à vide de dissolution de la coopération entre le moyen de retenue de l'élément de commande et le moyen de retenue du pêne à crochet en position de fermeture. De par les moyens mis en oeuvre par l'invention, le blocage du pêne à crochet, dans sa position de fermeture, se fait automatiquement. Le dégagement de ce blocage se fait également automatiquement au début de la manoeuvre de l'élément de commande avant que celui-ci n'entraîne le pêne à crochet vers sa position d'ouverture.The object of the present invention is to produce a latch of the above type in which the locking of the hook bolt in its closed position does not require a locking device operated by a key. The invention, as characterized in claim 1, makes it possible to achieve this object by providing a latch for sliding doors comprising a hook bolt articulated on the latch housing and controlled by a control element connecting it to a operating handle, an elastic element indirectly recalling the hook bolt in its closed position, means for retaining the hook bolt in the closed position and a pusher acting on the latter when the sliding leaf is closed to allow the return of the hook bolt in the closed position by the elastic element whose control element, acting on the hook bolt, is slidably housed in the housing and comprises a means of retaining means integral with the control element cooperating with the other means of the retaining means integral with the hook bolt in the closed position and that a connection between the control element and the hook bolt comprises a stroke to v ide of dissolution of the cooperation between the retaining means of the control element and the retaining means of the hook bolt in the closed position. By the means implemented by the invention, the locking of the hook bolt, in its closed position, is done automatically. The release of this blockage is also done automatically at the start of the operation of the control element before the latter causes the hook bolt to its open position.

De plus, ces moyens mis en oeuvre permettent que les moyens de retenue du pêne à crochet en position d'ouverture soient solidaires de l'élément de commande.In addition, these means used allow the means for retaining the hook bolt in the open position to be secured to the control element.

Selon un mode de réalisation avantageux de l'invention, on prévoit que le poussoir agissant sur les moyens de retenue coulisse dans le boîtier transversalement par rapport à l'élément de commande et coopère dans chacune de ses positions extrêmes avec un plan-butée et que l'écartement entre les plans-butées est égal à la course de la poignée.According to an advantageous embodiment of the invention, it is provided that the pusher acting on the retaining means slides in the housing transversely with respect to the control element and cooperates in each of its extreme positions with an abutment plane and that the distance between the abutment planes is equal to the stroke of the handle.

En effet, ces dernières dispositions permettent de réaliser des loquets nécessitant très peu d'encombrement et pouvant être équipés de garnitures pour fenêtres ou portes coulissantes à poignées coulissantes.Indeed, these latter arrangements make it possible to produce latches which require very little space and which can be fitted with fittings for windows or sliding doors with sliding handles.

Le cas échéant, ces garnitures peuvent être des garnitures comportant un bloc de sûreté transformant ainsi l'ensemble du loquet en une serrure de porte coulissante dès lors que l'élément élastique est un dispositif à double rappel inversé rappelant l'élément de commande, à partir de la mi-course, soit en position d'ouverture, soit en position de fermeture.Where appropriate, these linings can be linings comprising a safety block thus transforming the entire latch into a sliding door lock as soon as the elastic element is a double reverse inverted device recalling the control element, from the middle of the race, either in the open position or in the closed position.

Selon l'invention, les écarts de la cote nominale de saillie du poussoir provenant d'une pose plus ou moins précise du loguet dans l'ouvrant sont facilement compensés par des moyens de réglage prévoyant que le boîtier est fixé dans l'ouvrant par vis et contrevis.According to the invention, the deviations from the nominal projection dimension of the pusher originating from a more or less precise fitting of the loguet in the opening element are easily compensated by adjustment means providing that the housing is fixed in the opening element by screws. and reverse.

Lorsque le loquet présente une certaine longueur, les moyens de réglage peuvent avantageusement prévoir que la fixation du loquet comporte à une extrémité un axe permettant une légère oscillation contrôlée à l'autre extrémité par vis et contrevis.When the latch has a certain length, the adjustment means can advantageously provide that the latch fixing comprises at one end an axis allowing a slight oscillation controlled at the other end by screws and counter screws.

Les avantages obtenus grâce à cette invention consistent essentiellement en ce qu'en supprimant un nombre important de pièces, tel que biellette, élément basculant, bras de levier, liaison et axe d'articulation, on diminue, non seulement, le coût de revient dudit loquet, mais également les différents frottements des différentes pièces mobiles autour des axes d'articulation, ce qui permet de diminuer l'effort appliqué à la poignée de manoeuvre, pour vaincre tous ces frottements. Ainsi la manoeuvre du loquet est plus douce.The advantages obtained thanks to this invention consist essentially in that by eliminating a large number of parts, such as link, tilting element, lever arm, link and hinge pin, it not only reduces the cost price of said latch, but also the different friction of the different moving parts around the hinge pins, which reduces the force applied to the operating handle, to overcome all this friction. Thus the operation of the latch is smoother.

L'invention est exposée ci-après plus en détail à l'aide de dessins représentant seulement un mode d'exécution.The invention is set out below in more detail with the aid of drawings representing only one mode of execution.

La figure 1 représente, en vue partielle en élévation et en coupe, une fenêtre ou porte à ouvrants coulissants comportant un loquet conforme à l'invention.Figure 1 shows, in partial view in elevation and in section, a window or door with sliding doors having a latch according to the invention.

La figure 2 représente, en vue en coupe, le seul loquet selon ligne de coupe Il - Il de la figure 1. On se référe aux deux figures.Figure 2 shows, in sectional view, the only latch along the cutting line Il - Il of Figure 1. We refer to the two figures.

On dispose entre la paroi externe 1 et la paroi interne 2 d'un ouvrant coulissant 3 d'une fenêtre ou porte un loquet 4. Celui-ci comporte un boîtier 5 composé de deux moitiés de boîtier comportant chacune une paroi transversale 8, 9 et deux parois 6, 7 parallèles aux parois 1, 2 de l'ouvrant coulissant 3.There is between the external wall 1 and the internal wall 2 of a sliding opening 3 of a window or carries a latch 4. This comprises a housing 5 composed of two housing halves each comprising a transverse wall 8, 9 and two walls 6, 7 parallel to the walls 1, 2 of the sliding leaf 3.

Le boîtier 5 comporte un pêne à crochet 10 pouvant pivoter autour d'un axe 11 solidaire dudit boîtier 5. A cet effet, les parois 6, 7 des deux moitiés de boîtier du boîtier 5 présentent une lumière 12 faisant face à une lumière 13 réalisée dans la paroi interne 2 de l'ouvrant coulissant 3. Ces lumières 12, 13 permettent le passage du pêne à crochet 10 dont le crochet 14, en position de fermeture du loquet 4, fait saillie par rapport à la face externe 15 de la paroi interne 2 de l'ouvrant coulissant 3. Ce crochet 14 coopère avec un contrecrochet 16 d'une gâche 17 solidaire du dormant 18 de la fenêtre ou porte. Cette gâche 17 est constituée d'un élément interne 19 appliqué contre la face interne 20 du dormant 18 et d'un élément externe 21 appliqué contre la face externe 22 dudit dormant 18. L'élément interne 19 comporte sur sa face 23 dirigée vers l'élément externe 21 un bossage 24 traversant une lumière 25 pratiquée dans la paroi 26 du dormant 18. Ces deux éléments 19 et 21 sont maintenus ensemble par des éléments de fixation 27, 28 traversant également la lumière 25. Du fait que le bossage 24 et les éléments de fixation 27, 28 traversent la lumière 25, il est possible de positionner la gâche 17 par rapport à ladite lumière 25 en fonction de la position du pêne à crochet 10.The housing 5 comprises a hook bolt 10 which can pivot about an axis 11 integral with said housing 5. For this purpose, the walls 6, 7 of the two housing halves of the housing 5 have a light 12 facing a light 13 made in the internal wall 2 of the sliding leaf 3. These slots 12, 13 allow the passage of the hook bolt 10, the hook 14 of which, in the closed position of the latch 4, projects relative to the external face 15 of the wall internal 2 of the sliding leaf 3. This hook 14 cooperates with a counter-hook 16 of a keeper 17 secured to the frame 18 of the window or door. This keeper 17 consists of an internal element 19 applied against the internal face 20 of the frame 18 and an external element 21 applied against the external face 22 of said frame 18. The internal element 19 has on its face 23 directed towards the external element 21 a boss 24 passing through a lumen 25 formed in the wall 26 of the frame 18. These two elements 19 and 21 are held together by fastening elements 27, 28 also passing through the lumen 25. Because the boss 24 and the fastening elements 27, 28 pass through the lumen 25, it is possible to position the keeper 17 relative to said lumen 25 as a function of the position of the hook bolt 10.

Ce dernier est actionné par un élément de commande 29. Conformément à l'invention, cet élément de commande 29 coulisse à l'intérieur du boîtier 5 selon un mouvement parallèle aux parois 1, 2 de l'ouvrant coulissant 3. Cet élément de commande 29 comporte approximativement, une section en "U", vue en plan, dont l'ouverture est située du côté de la paroi interne 2 de l'ouvrant coulissant 3. Les faces internes 30, 31, 32, 33 des parois 6, 7, 8, 9, du boîtier 5 servent de guide à l'élément de commande 29. Ce dernier relie le pêne à crochet 10 à une poignée de manoeuvre 34 représentée dans la figure 1 par son axe de liaison 35. Cet axe de liaison 35 traverse des lumières 36, 37, pratiquées dans les deux ailes parallèles 38, 39 de l'élément de commande 29 et des lumières 40, 41 réalisées dans les parois transversales 8, 9 du boîtier 5. L'axe longitudinal 42 des lumières 36, 37 est perpendiculaire au coulissement de l'élément de commande 29 alors que l'axe longitudinal des lumières 40, 41 est parallèle à ce coulissement. Le pêne à crochet 10 est relié à l'élément de commande 29 par une liaison 43 comportant une course à vide 44. Cette liaison 43 est composée par un axe transversal 45 solidaire du pêne à crochet 10 et de deux lumières 46, 47 réalisées également dans les deux ailes parallèles 38, 39 de l'élément de commande 29, ledit pêne à crochet 10 étant disposé entre les deux ailes parallèles 38, 39.The latter is actuated by a control element 29. According to the invention, this control element 29 slides inside the housing 5 according to a movement parallel to the walls 1, 2 of the sliding leaf 3. This control element 29 comprises approximately a "U" section, plan view, the opening of which is situated on the side of the internal wall 2 of the sliding leaf 3. The internal faces 30, 31, 32, 33 of the walls 6, 7 , 8, 9, of the housing 5 serve as a guide for the control element 29. The latter connects the hook bolt 10 to an operating handle 34 represented in FIG. 1 by its connection axis 35. This connection axis 35 crosses lights 36, 37, formed in the two parallel wings 38, 39 of the control element 29 and lights 40, 41 produced in the transverse walls 8, 9 of the housing 5. The longitudinal axis 42 of the lights 36, 37 is perpendicular to the sliding of the control element 29 while the longitudinal axis of the lights 40, 41 is parallel to this sliding. The hook bolt 10 is connected to the control element 29 by a link 43 comprising an idle stroke 44. This link 43 is composed by a transverse axis 45 secured to the hook bolt 10 and two slots 46, 47 also produced in the two parallel wings 38, 39 of the control element 29, said hook bolt 10 being arranged between the two parallel wings 38, 39.

Le rappel du pêne à crochet 10 en position de fermeture tel que représenté dans la figure 1 est assuré par un élément élastique 48. Cet élément élastique 48 est intercalé entre un arrêt 49 solidaire de l'élément de commande 29 et un arrêt 50 solidaire du boîtier 5. Chaque arrêt 49, 50 comporte un guide 51, 52 sur lequel est enfilée une des extrémités 53, 54 de l'élément élastique 48.The return of the hook bolt 10 in the closed position as shown in FIG. 1 is ensured by an elastic element 48. This elastic element 48 is interposed between a stop 49 secured to the control element 29 and a stop 50 secured to the housing 5. Each stop 49, 50 comprises a guide 51, 52 on which is threaded one of the ends 53, 54 of the elastic element 48.

Pour condamner le pêne à crochet 10 dans sa position de fermeture et ainsi interdire tout essai d'effraction par action sur lédit pêne à crochet 10 en glissant une lame par exemple entre l'ouvrant coulissant 3 et le dormant 18, on prévoit des moyens de retenue 55 assurant le blocage du pêne à crochet 10 dans sa position de fermeture. Selon un premier mode de réalisation, ces moyens de retenue 55 comportent, d'une part, un cran 56 réalisé dans le pêne à crochet 10 et, d'autre part, un arrêt 57 solidaire de l'élément de commande 29. En position de fermeture, le chant d'action 58 du cran 56 du pêne à crochet 10 prend appui contre le chant de retenue 59 de l'arrêt 57 de l'élément de commande 29. Il est donc impossible de provoquer le basculement du pêne à crochet 10 en vue de son effacement libérant l'ouvrant coulissant 3. La profondeur d'engagement de l'arrêt 57 dans le cran 56 est légèrement inférieure à la course à vide 44 de la liaison 43 entre le pêne à crochet 10 et l'élément de commande 29.To condemn the hook bolt 10 in its closed position and thus prohibit any break-in test by action on the said hook bolt 10 by sliding a blade for example between the sliding leaf 3 and the frame 18, means are provided for retainer 55 ensuring the locking of the hook bolt 10 in its closed position. According to a first embodiment, these retaining means 55 comprise, on the one hand, a notch 56 produced in the hook bolt 10 and, on the other hand, a stop 57 secured to the control element 29. In position closing, the action edge 58 of the notch 56 of the hook bolt 10 bears against the retaining edge 59 of the stop 57 of the control element 29. It is therefore impossible to cause the tilting of the hook bolt 10 in view of its erasure releasing the sliding leaf 3. The depth of engagement of the stop 57 in the notch 56 is slightly less than the idle stroke 44 of the connection 43 between the hook bolt 10 and the element 29.

Selon un second mode de réalisation, ces moyens de retenue 55 se composent d'un têton faisant saillie par rapport à la face inférieure de l'arrêt 57 coopérant avec un logement réalisé dans le pêne à crochet 10.According to a second embodiment, these retaining means 55 consist of a stud projecting from the underside of the stop 57 cooperating with a housing produced in the hook bolt 10.

Inversement, ces moyens de retenue 55 peuvent être constitués d'un doigt de commande situé à la partie supérieure du pêne à crochet 10 et d'un logement pratiqué dans l'arrêt 57.Conversely, these retaining means 55 may consist of a control finger located at the upper part of the hook bolt 10 and of a housing provided in the stop 57.

La pénétration du têton ou du doigt de commande, respectivement, dans le logement du pêne à crochet 10 ou dans le logement de l'arrêt 57 est légèrement inférieure à la course à vide 44 de la liaison 43 entre le pêne à crochet 10 et l'élément de commande 29.The penetration of the pin or the control finger, respectively, in the housing of the hook bolt 10 or in the housing of the stop 57 is slightly less than the no-load stroke 44 of the connection 43 between the hook bolt 10 and the control element 29.

Pour le dégagement du blocage du pêne à crochet 10, on actionne la poignée de manoeuvre 34 provoquant un début de coulissement de l'élément de commande 29. Ce début de coulissement entraîne la dissolution de la coopération entre le cran 56 et l'arrêt 57. Au cours de ce début de coulissement, le pêne à crochet 10 n'est pas entraîné vers sa position d'ouverture du fait que la liaison 43, notamment l'axe 45 se déplace dans les lumières 46, 47. Ce n'est que lorsque le chant inférieur 60, 61 des lumières 46, 47 entre en contact avec l'axe 45 que le pêne à crochet 10 est actionné par l'élément de commande 29.To release the blocking of the hook bolt 10, the operating handle 34 is actuated, causing the sliding element of the control element 29 to start to slide. This sliding start causes the cooperation between the catch 56 and the stop 57 to dissolve. During this start of sliding, the hook bolt 10 is not driven towards its open position because the link 43, in particular the axis 45 moves in the slots 46, 47. This is not that when the song lower 60, 61 of the lights 46, 47 comes into contact with the axis 45 that the hook bolt 10 is actuated by the control element 29.

Par ailleurs, le loquet 4 comporte un poussoir 62. Celui-ci traverse une lumière 63 pratiquée dans les parois 7 du boîtier 5 et la lumière 13 de la paroi interne 2 de l'ouvrant coulissant 3. Le poussoir 62 coulisse transversalement par rapport à l'élément de commande 29 et il est rappelé élastiquement en position saillante par un élément élastique 64 interposé entre le fond 65 d'un alésage 66 réalisé dans la face arrière 67 du poussoir 62 et la face interne 30 de la paroi 6 du boîtier 5.Furthermore, the latch 4 comprises a pusher 62. The latter passes through a lumen 63 formed in the walls 7 of the housing 5 and the lumen 13 of the internal wall 2 of the sliding leaf 3. The pusher 62 slides transversely relative to the control element 29 and it is resiliently returned to the projecting position by an elastic element 64 interposed between the bottom 65 of a bore 66 formed in the rear face 67 of the pusher 62 and the internal face 30 of the wall 6 of the housing 5 .

La face arrière 67 est pourvue d'un coulisseau transversal 68 dont les extrémités 69, 70, se déplacent dans des lumières 71,72 réalisées dans les parois transversales 8, 9 du boîtier 5. On pratique dans les ailes parallèles 38, 39, de l'élément de commande 29 des lumières 73, 74. Ces lumières 73, 74 ont approximativement la forme d'une équerre, ce qui permet d'obtenir deux plans-butées 75, 76, chaque plan-butée 75, 76 correspondant à une des positions extrêmes de l'élément de commande 29. L'un des plans- butées 75 est constitué par le chant supérieur de l'aile verticale de la lumière en forme d'équerre 73, 74 alors que l'autre plan-butée 76 est formé par le chant supérieur de l'aile horizontale de la lumière en forme d'équerre 73, 74.The rear face 67 is provided with a transverse slide 68, the ends 69, 70 of which move in slots 71, 72 made in the transverse walls 8, 9 of the housing 5. In the parallel wings 38, 39, the control element 29 of the lights 73, 74. These lights 73, 74 have approximately the shape of a square, which makes it possible to obtain two abutment planes 75, 76, each abutment plane 75, 76 corresponding to a extreme positions of the control element 29. One of the abutment planes 75 is constituted by the upper edge of the vertical wing of the light in the form of a square 73, 74 while the other abutment plane 76 is formed by the upper edge of the horizontal wing of the square light 73, 74.

L'écartement 77 entre los plans-butées 75, 76 est égal à la course de la poignée de manoeuvre 34 et, par voie de conséquence, à la course de l'élément de commande 29.The spacing 77 between the abutment planes 75, 76 is equal to the stroke of the operating handle 34 and, consequently, to the stroke of the control element 29.

Le fonctionnement du loquet est le suivant:The operation of the latch is as follows:

On actionne la poignée de manoeuvre 34 provoquant un début de coulissement de l'élément de commande 29 entraînant la dissolution de la coopération de l'arrêt 57 et du cran 56. En continuant d'actionner la poignée de manoeuvre 34, le chant inférieur 60, 61 des lumières 46, 47 entraîne l'axe 45 provoquant la rotation du pêne à crochet 10 autour de l'axe 11 et, de ce fait, l'ouverture du loquet 4.The operating handle 34 is actuated, causing the start of sliding of the control element 29, causing the cooperation of the stop 57 and the notch 56 to dissolve. While continuing to operate the operating handle 34, the lower edge 60 , 61 of the lights 46, 47 drives the axis 45 causing the rotation of the hook bolt 10 about the axis 11 and, therefore, the opening of the latch 4.

Simultanément, on provoque la compression de l'élément élastique 48. Au cours du déplacement de l'élément de commande 29, les lumières en forme d'équerre 73, 74 glissent le long du coulisseau transversal 68 du poussoir 62 jusqu'à ce que le chant inférieur desdites lumières 73, 74 vient buter contre le chant inférieur du coulisseau transversal 68. En déplaçant l'ouvrant coulissant 3, l'élément élastique 64 se détend en poussant le puussoir 62 vers l'extérieur. Le plan-butée 76 empêche le retour de l'élément de commande 29 sous la poussée de l'élément élastique 48.Simultaneously, the elastic element 48 is compressed. During the movement of the control element 29, the square-shaped slots 73, 74 slide along the transverse slide 68 of the pusher 62 until the lower edge of said slots 73, 74 abuts against the lower edge of the transverse slide 68. By moving the sliding leaf 3, the elastic element 64 relaxes by pushing the puussoir 62 outwards. The abutment plane 76 prevents the return of the control element 29 under the thrust of the elastic element 48.

En fermant l'ouvrant coulissant 3, la gâche 17 repousse le poussoir 62 en comprimant l'élément élastique 64 de sorte que le coulisseau transversal 68 vient se placer dans l'aile verticale des lumières en forme d'équerre 73, 74 libérant l'action de l'élément élastique 48. Ce dernier se détend et repousse l'élément de commande 29 jusqu'à ce que le plan-butée 75 prend appui contre le chant supérieur du coulisseau transversal 68. L'action des lumières 46, 47 sur l'axe 45 provoque la coopération du cran 56 avec l'arrêt 57 alors que le coulissement de l'élément de commande 29 dans le boîtier 5 entraîne le retour de la poignée de manoeuvre 34.By closing the sliding leaf 3, the keeper 17 pushes the pusher 62 by compressing the elastic element 64 so that the transverse slide 68 comes to be placed in the vertical wing of the square-shaped lights 73, 74 releasing the action of the elastic element 48. The latter relaxes and pushes back the control element 29 until the abutment plane 75 bears against the upper edge of the transverse slide 68. The action of the lights 46, 47 on the axis 45 causes the notch 56 to cooperate with the stop 57 while the sliding of the control element 29 in the housing 5 causes the operating handle 34 to return.

Par ailleurs, le loquet 4 peut être équipe de garnitures puur fenêtres ou portes coulissantes à poignées coulissantes. Le cas échéant, ces garnitures peuvent être des garnitures comportant un bloc ce sûreté transformant le luquet en une serrure de porte coulissante. A cet effet, on prévoit un dispositif à double rappel inversé 78 rappelant l'élément de commande 29, à partir de la mi-course, soit en position d'ouverture, soit en position de fermeture.Furthermore, the latch 4 can be fitted with fittings for windows or sliding doors with sliding handles. If necessary, these fittings can be fittings comprising a block that transforms the safety latch into a sliding door lock. To this end, a double inverted return device 78 is provided, recalling the control element 29, from mid-stroke, either in the open position or in the closed position.

Ce dispositif à double rappel inversé 78 comporte un élément élastique 79 dont les deux extrémités 80, 81 sont enfilées sur des axes 82, 83 de deux bascules 84, 85. La tête 86 de la bascule 85 peut pivoter dans un logement 87 réalisé dans la paroi transversale 88 de l'élément de commande 29 alors que la tête 89 de la bascule 84 peut pivoter dans un logement 90 pratiqué dans les parois 7 du boîtier 5. Le logement 90 est fixe alors que le logement 87 se déplace d'une position basse, correspondant à la position de fermeture, à une position haute, correspondant à la position d'ouverture du loquet 4. L'écartement entre la position basse et la position haute est égal à la course de la poignée de manoeuvre 34. En actionnant cette dernière et, en conséquence, l'élément de commande 29, on comprime l'élément élastique 79. Dès que l'élément de commande 29 a dépassé la mi-course, l'élément élastique 79 se détenu en agissant sur l'élément de commande 29 pour que ce dernier occupe vraiment sa position d'ouverture ou sa position de fermeture.This inverted double return device 78 comprises an elastic element 79, the two ends 80, 81 of which are threaded on axes 82, 83 of two rockers 84, 85. The head 86 of rocker 85 can pivot in a housing 87 produced in the transverse wall 88 of the control element 29 while the head 89 of the rocker 84 can pivot in a housing 90 formed in the walls 7 of the housing 5. The housing 90 is fixed while the housing 87 moves from one position low, corresponding to the closed position, to a high position, corresponding to the open position of the latch 4. The distance between the low position and the high position is equal to the stroke of the operating handle 34. By actuating the latter and, consequently, the control element 29, the elastic element 79 is compressed. As soon as the control element 29 has passed halfway, the elastic element 79 is held in place by acting on the element order 29 so that the latter really occupies its positi on opening or its closed position.

Cependant, pour un bon fonctionnement du loquet 4, il est nécessaire que la cote nominale de saillie du poussoir 62 par rapport à la face externe 15 soit au moins égale à la largeur du plan-butée 76 pour permettre la saillie du pêne à crochet 10. En raison d'une pose plus ou moins précise du loquet 4 dans l'ouvrant coulissant 3, cette cote nominale peut être insuffisante ce qui empêche le fonctionnement du loquet 4. En effet, si la course du poussoir 62 n'est pas conforme à la cote de saillie nominale, il y a défaillance du mécanisme assurant la fermeture du pêne à crochet 10.However, for proper operation of the latch 4, it is necessary that the nominal projection dimension of the pusher 62 relative to the external face 15 is at least equal to the width of the abutment plane 76 to allow the projection of the hook bolt 10 Due to a more or less precise positioning of the latch 4 in the sliding leaf 3, this nominal dimension may be insufficient, which prevents the latch 4 from operating. In fact, if the stroke of the pusher 62 is not in conformity at the nominal projection dimension, there is a failure of the mechanism ensuring the closing of the hook bolt 10.

A cet effet, il est prévu des moyens de réglage permettant de modifier la position du loquet 4 par rapport à la paroi interne 2 de l'ouvrant coulissant 3.To this end, adjustment means are provided making it possible to modify the position of the latch 4 relative to the internal wall 2 of the sliding leaf 3.

Selon un premier mode de réalisation, ces moyens de réglage sont constitués de vis 91, 92 et de contrevis 93 disposées aux extrémités 94, 95 du boîtier 5 et assurant la fixation du loquet 4 sur l'ouvrant coulissant 3.According to a first embodiment, these adjustment means consist of screws 91, 92 and of a counter screw 93 arranged at the ends 94, 95 of the housing 5 and ensuring the fixing of the latch 4 on the sliding leaf 3.

Selon un second mode de réalisation particulièrement avantageux, lorsque le loquet 4 atteint une certaine longueur, ces moyens de réglage comportent un moyeu 96 fixé sur la paroi interne 2 de l'ouvrant coulissant 3 par la vis 91. Ce moyeu 96 est pourvu d'un tourillon 97 traversant des alésages 98, 99 réalisés dans des prolongements 100, 101 des extrémités supérieures des parois transversales 8, 9 du boîtier 5. De ce fait, le loquet 4 peut légèrement osciller autour du tourillon 97 et sa position est contrôlée par la vis 92 et la contrevis 93 agissant sur l'extrémité inférieure 95 du loquet 4. Ainsi, les écarts de la cote nominale de saillie du poussoir 62 peuvent être compensés.According to a second particularly advantageous embodiment, when the latch 4 reaches a certain length, these adjustment means comprise a hub 96 fixed to the internal wall 2 of the sliding leaf 3 by the screw 91. This hub 96 is provided with a journal 97 passing through bores 98, 99 produced in extensions 100, 101 of the upper ends of the transverse walls 8, 9 of the housing 5. As a result, the latch 4 can slightly oscillate around the journal 97 and its position is controlled by the screw 92 and the counter screw 93 acting on the lower end 95 of the latch 4. Thus, the deviations from the nominal projection dimension of the pusher 62 can be compensated.
