Description

L'invention a trait à une ferrure de verrouillage pour ouvrant coulissant de fenêtre, porte ou analogue comprenant, dans son boîtier, un coulisseau relié à un pêne à crochet coopérant avec une gâche solidaire du dormant et maintenu par un dispositif de condamnation présentant un levier de condamnation à rappel élastique dont l'extrémité supérieure peut prendre appui contre le chant inférieur du crochet du pêne à crochet condamnant la manoeuvre du coulisseau en position de verrouillage lorsque l'ouvrant coulissant se dégage du dormant.The invention relates to a locking fitting for a sliding window, door or similar opening comprising, in its housing, a slide connected to a hook bolt cooperating with a keeper secured to the frame and held by a locking device having a lever. elastic return lock whose upper end can bear against the lower edge of the hook of the hook bolt condemning the operation of the slide in the locked position when the sliding leaf is released from the frame.

On connaît déjà, par la demande de brevet EP-A 0 246 172, considérée au titre de l'Art. 54 (3) et (4) de la CBE, une ferrure de verrouillage, notamment pour ouvrant coulissant de fenêtre, porte ou analogue, comprenant dans son boîtier un coulisseau relié à un pêne à crochet coopérant avec une gâche solidaire du dormant et maintenu dans sa position d'ouverture par un dispositif de condamnation à rappel élastique.We already know, by patent application EP-A 0 246 172, considered under Art. 54 (3) and (4) of the EPC, a locking fitting, in particular for a sliding window, door or the like opening, comprising in its housing a slide connected to a hook bolt cooperating with a keeper secured to the frame and held in its open position by an elastic return locking device.

Ce dispositif de condamnation comporte un guide situé au-dessus de la vis de fixation et de réglage du pêne à crochet et coulissant dans un logement traversant de part en part le porte-pêne solidaire du coulisseau. Ledit guide, soumis à un déplacement perpendiculaire au sens de déplacement du coulisseau, sert de support à un palpeur.This locking device comprises a guide located above the screw for fixing and adjusting the hook bolt and sliding in a housing passing right through the bolt holder secured to the slide. Said guide, subjected to a movement perpendicular to the direction of movement of the slide, serves as a support for a probe.

En position d'ouverture, l'ensemble guide-palpeur est poussé vers l'extérieur par un élément élastique tel que le palpeur fasse saillie par rapport au chant de l'ouvrant et qu'un bossage du guide coopère avec un plan-butée obtenu par un décrochement réalisé dans l'une des deux parois parallèles du boîtier. En refermant l'ouvrant, le palpeur prend appui contre la gâche et provoque le déplacement vers l'arrière du guide, ce qui entraîne la dissolution de la coopération entre le bossage du guide et le plan-butée du décrochement de la paroi du boîtier. De ce fait, on peur ramener le coulisseau à sa position de verrouillage.In the open position, the probe-guide assembly is pushed outwards by an elastic element such that the probe protrudes relative to the edge of the opening and that a boss of the guide cooperates with a plane-stop obtained. by a recess produced in one of the two parallel walls of the housing. By closing the opening, the feeler bears against the strike plate and causes the guide to move towards the rear, which causes the cooperation between the boss of the guide and the abutment plane of the recess of the housing wall to dissolve. Therefore, we fear return the slide to its locked position.

Toutefois, cette ferrure présente plusieurs inconvénients. En effet, du fait que le guide coulisse dans un logement réalisé dans le porte-pêne du coulisseau, soit le porte-pêne est surdimensionné, notamment en ce qui concerne son épaisseur, ce qui entraîne une augmentation de l'épaisseur du boîtier, et par voie de conséquence, de l'ouvrant, soit le dispositif de condamnation à rappel élastique est relativement petit, ce qui diminue la fiabilité dudit dispositif. Par ailleurs, ce dernier n'est utilisable qu'avec un porte-pêne déterminé spécialement conçu.However, this fitting has several drawbacks. Indeed, the fact that the guide slides in a housing produced in the bolt holder of the slide, or the bolt holder is oversized, in particular as regards its thickness, which leads to an increase in the thickness of the housing, and Consequently, the opening, or the elastic return locking device is relatively small, which reduces the reliability of said device. Furthermore, the latter can only be used with a specific bolt holder specially designed.

On connaît également, par le document US-A 4 489 966 ayant servi de base pour le préambule de la revendication 1, une ferrure de verrouillage pour ouvrant d'une fenêtre, porte ou analogue pivotant autour d'un axe vertical. Cette ferrure comprend, dans son boîtier, un coulisseau à rappel élastique pour conférer à des éléments de verrouillage une position automatique de verrouillage. Ces éléments de verrouillage sont constitués d'un pêne coopérant avec une première gâche et d'une tringle de verrouillage coopérant avec une seconde gâche, les éléments de verrouillage étant solidaires du coulisseau et les gâches étant solidaires du dormant. Lors de la fermeture de l'ouvrant, ces gâches traversent des lumières réalisées dans le boîtier. On prévoit également un dispositif de condamnation présentant un levier de condamnation à rappel élastique. L'extrémité supérieure du levier de condamnation peut prendre appui contre le chant inférieur de la tringle de verrouillage pour maintenir la ferrure en position déverrouillée, le point de contact entre l'extrémité supérieure du levier de condamnation et le chant inférieur de la tringle de verrouillage étant situé au-dessus du chant supérieur de la lumière permettant la pénétration de la gâche correspondante dans le boîtier. En cas de fermeture, cette gâche repousse le levier de condamnation et, sous l'effet de l'élément élastique reliant le coulisseau au boîtier, la ferrure se met automatiquement en position de verrouillage et la tringle de verrouillage traverse automatiquement la lumière réalisée dans la gâche correspondante.Also known, from document US-A 4 489 966 having served as a basis for the preamble of claim 1, a locking fitting for opening a window, door or the like pivoting about a vertical axis. This fitting comprises, in its housing, an elastic return slide to give the locking elements an automatic locking position. These locking elements consist of a bolt cooperating with a first strike and a locking rod cooperating with a second strike, the locking elements being secured to the slide and the strikes being secured to the frame. When the opening is closed, these strikes pass through lights made in the housing. There is also a locking device having a locking lever with elastic return. The upper end of the locking lever can bear against the lower edge of the locking rod to keep the fitting in the unlocked position, the point of contact between the upper end of the locking lever and the lower edge of the locking rod being located above the upper edge of the light allowing the penetration of the corresponding strike in the housing. When closed, this keeper pushes the locking lever and, under the effect of the elastic element connecting the slider to the housing, the fitting automatically goes into the locking position and the locking rod automatically passes through the light produced in the corresponding keeper.

Toutefois, cette ferrure présente plusieurs inconvénients. En effet, pour chaque ouverture de l'ouvrant, l'usager est obligé de conférer à la ferrure une position de déverrouillage en actionnant la ferrure. Par ailleurs, du fait qu'il existe une certaine distance entre le point de contact levier de condamnation - tringle de verrouillage et le dessus de la gâche correspondante, l'ouverture de l'ouvrant est possible sans que le levier de condamnation s'est positionné sous la tringle de verrouillage et, après ouverture, la ferrure revient automatiquement en position de verrouillage. Finalement, le dispositif de condamnation ne peut être utilisé que pour des ferrures comportant une tringle de verrouillage.However, this fitting has several drawbacks. Indeed, for each opening of the opening, the user is obliged to give the fitting an unlocking position by actuating the fitting. Furthermore, because there is a certain distance between the point of contact of the locking lever - locking rod and the top of the corresponding keeper, the opening of the leaf is possible without the locking lever having positioned under the locking rod and, after opening, the fitting automatically returns to the locking position. Finally, the locking device can only be used for fittings comprising a locking rod.

La présente invention a pour but de remédier à ces inconvénients. L'invention, telle qu'elle est caractérisée dans la revendication 1 permet de parvenir à cet objectif en prévoyant une ferrure de verrouillage pour ouvrant de fenêtre, porte ou analogue comprenant, dans son boîtier, un coulisseau relié à un pêne à crochet coopérant avec une gâche solidaire du dormant et maintenu par un dispositif de condamnation présentant un levier de condamnation à rappel élastique dont l'extrémité supérieure peut prendre appui contre le chant inférieur du crochet du pêne à crochet, empêchant la manoeuvre du coulisseau vers sa position de verrouillage avec la gâche lorsque l'ouvrant coulissant se dégage du dormant qui se caractérise en ce que la ferrure de verrouillage est prévue pour un ouvrant coulissant et en ce que le dispositif de condamnation comporte un support logé entre deux ailes d'un profilé de section en "U" de l'ouvrant coulissant et dont la face arrière comprend un bossage s'engageant dans une lumière réalisée dans le fond du profilé en prenant appui, par son épaulement inférieur, contre te chant inférieur de cette lumière, le positionnement de ce support étant bloqué par des moyens de maintien de celui-ci coopérant avec des moyens de complémentarité de l'ouvrant coulissant.The present invention aims to remedy these drawbacks. The invention, as characterized in claim 1, achieves this objective by providing a locking fitting for window, door or the like opening comprising, in its housing, a slide connected to a hook bolt cooperating with a keeper secured to the frame and held by a locking device having a locking lever with elastic return, the upper end of which can bear against the lower edge of the hook of the hook bolt, preventing the slide from operating towards its locking position with the keeper when the sliding leaf emerges from the frame which is characterized in that the locking fitting is provided for a sliding leaf and in that the locking device comprises a support housed between two wings of a sectional profile in " U "of the sliding sash and the rear face of which comprises a boss engaging in a light made in the background d of the profile by taking support, by its lower shoulder, against the lower edge of this light, the positioning of this support being blocked by means for holding it cooperating with means of complementarity of the sliding leaf.

Les avantages obtenus grâce à cette invention consistent essentiellement en ce que le dispositif de condamnation n'est plus tributaire de l'épaisseur du porte-pêne et peut donc être renforcé, ce qui diminue son endommagement et augmente sa fiabilité. En outre, étant un ensemble séparé, le dispositif de condamnation peut être mis en place sur les ouvrants coulissants existants, pourvus déjà d'une ferrure de verrouillage.The advantages obtained thanks to this invention essentially consist in that the locking device is no longer dependent on the thickness of the bolt holder and can therefore be reinforced, which dimi bare its damage and increases its reliability. In addition, being a separate assembly, the locking device can be put in place on existing sliding doors, already provided with a locking fitting.

Par ailleurs, la réalisation du coulisseau et. du porte-pêne est simplifiée, ce qui influence également leur fiabilité, tout en permettant de diminuer leur coût de revient. Un autre avantage consiste en ce que le dispositif de condamnation vient se placer sous la gâche lors de la fermeture de l'ouvrant coulissant et il devient impossible de soulever ce dernier. De ce fait, le dispositif de condamnation joue également un rôle de sécurité en annihilant toute tentative de dégonder l'ouvrant coulissant. Finalement, il est possible de manoeuvrer à volonté l'ouvrant et la ferrure n'est mise en position de verrouillage qu'après une manoeuvre délibérée de l'usager, manoeuvre possible uniquement lorsque l'ouvrant est en position de fermeture.Furthermore, the realization of the slide and. of the bolt holder is simplified, which also influences their reliability, while making it possible to reduce their cost price. Another advantage is that the locking device is placed under the striker when the sliding door is closed and it becomes impossible to lift the latter. Therefore, the locking device also plays a security role by annihilating any attempt to unhook the sliding door. Finally, it is possible to maneuver the opening at will and the fitting is only put in the locking position after a deliberate maneuver by the user, maneuvering possible only when the opening is in the closed position.

On pratique dans le fond 27 de ce profilé 26 une lumière 28 permettant le passage et le déplacement vertical du pêne à crochet 22. Le pêne à crochet 22 coopère avec une gâche 29 solidaire du dormant 30 et logée entre les ailes 31, 32 d'un profilé 33 constituant le chant du dormant 30.The locking fitting 2 comprises a housing 15 consisting of two walls 16, 17 between which a slide 18 can be moved, which can be actuated by a handle 19 through a light 20 made in the inner plate 8. The slide 18 is integral with a bolt holder 21 serving as a support for a hook bolt 22 disposed perpendicularly to the direction of movement of the slide 18. This hook bolt 22 comprises at least one hook 23 directed downwards. This hook bolt 22, projecting relative to the wall 17 of the housing 15, moves between the two wings 24, 25 of a profile 26 having a section in the shape of a "U" and constituting the edge of the sliding leaf 1. A hole 28 is made in the bottom 27 of this profile 26 allowing the passage and the vertical displacement of the hook bolt 22. The hook bolt 22 cooperates with a keeper 29 integral with the frame 30 and housed between the wings 31, 32 a profile 33 constituting the edge of the frame 30.

La ferrure de verrouillage 2 comporte un dispositif de condamnation 34. Celui-ci est formé essentiellement d'un support 35 pourvu de moyens de maintien et de positionnement et d'un levier de condamnation 36.The locking fitting 2 includes a locking device 34. This essentially consists of a support 35 provided with holding and positioning means and a locking lever 36.

Le support 35 est logé entre les deux ailes 24, 25 du profilé 26 et sa largeur 37 est légèrement inférieure à l'espace 38 situé entre les faces internes 39, 40 des deux ailes 24, 25. La face arrière 41 du support 35, appliquée contre le fond 27 du profilé 26, comporte un bossage 42 s'engageant également dans la lumière 28 réalisée dans ledit fond 27 du profilé 26. L'épaulement inférieur 43 de ce bossage 42 prend appui contre le chant inférieur 44 de la lumière 28. Ce chant inférieur 44 de la lumière 28 constitue un des moyens de complémentarité de l'ouvrant coulissant 1 permettant le positionnement du dispositif de condamnation 34. Cet épaulement inférieur 43 de ce bossage 42 et le chant inférieur 44 de la lumière 28 constituent les moyens de positionnement du dispositif de condamnation 34. La hauteur 45 de ce bossage 42 est légèrement inférieure à l'épaisseur 46 du fond 27 du profilé 26 pour éviter que la face arrière 47 du bossage 42 gêne le déplacement du coulisseau 18.The support 35 is housed between the two wings 24, 25 of the profile 26 and its width 37 is slightly less than the space 38 located between the internal faces 39, 40 of the two wings 24, 25. The rear face 41 of the support 35, applied against the bottom 27 of the profile 26, has a boss 42 also engaging in the slot 28 formed in said bottom 27 of the profile 26. The lower shoulder 43 of this boss 42 bears against the lower edge 44 of the slot 28 This lower edge 44 of the light 28 constitutes one of the means of complementarity of the sliding opening 1 allowing the positioning of the locking device 34. This lower shoulder 43 of this boss 42 and the lower edge 44 of the light 28 constitute the means positioning the locking device 34. The height 45 of this boss 42 is slightly less than the thickness 46 of the bottom 27 of the profile 26 to prevent the rear face 47 of the boss 42 from hampering the movement slider cement 18.

La face arrière 41 est reliée à la face avant 48 par deux parois inclinées 49, 50. Cette face avant 48, décalée vers le bas par rapport à la face arrière 41, prend appui contre deux bossages verticaux 51, 52 faisant saillie des deux faces internes 39, 40 des deux ailes 24, 25 du profilé 26 en direction du plan médian 53. La face avant 48 comporte un bossage 54 dans lequel est pratiqué un trou 55. On engage dans ce dernier un élément de serrage 56 dont la pointe tronquée 57 prend appui contre le fond 27 du profilé 26. Avantageusement, l'élément de serrage 56 est une vis et, par voie de conséquence, le trou 55 est un trou taraudé. La face arrière 41 présente un dégagement 58 de sorte que l'élément de serrage 56 peut faire saillie. Ainsi, les moyens de blocage du dispositif de condamnation 34 sont constitués par la vis 56. En effet, en actionnant cette dernière, on a tendance à conférer au support 35 une certaine rotation par rapport à l'épaulement inférieur 43 du bossage 42 de sorte que la face arrière 41 du support 35 se plaque contre le fond 27 du profilé 26 alors que la face avant 48 se plaque contre les bossages verticaux 51, 52 des deux ailes 24, 25 du profilé 26 et qu'on obtient ainsi deux zones de serrage opposées. Ainsi, le fond 27 du profilé 26 et les deux bossages verticaux 51, 52 des deux ailes 24, 25 du profilé 26 constituent d'autres moyens de complémentarité de l'ouvrant coulissant 1 permettant de maintenir dans sa position le dispositif de condamnation 34. On pratique dans le corps 59 du support 35 une saignée verticale 60 dans laquelle est disposé le levier de condamnation 36. Celui-ci peut pivoter autour d'un axe 61 dont les extrémités 62, 63 sont engagées dans des orifices 64, 65 réalisés dans les faces 66, 67 du corps 59.The rear face 41 is connected to the front face 48 by two inclined walls 49, 50. This front face 48, offset downward relative to the rear face 41, bears against two vertical bosses 51, 52 projecting from the two faces internal 39, 40 of the two wings 24, 25 of the profile 26 in the direction of the median plane 53. The front face 48 has a boss 54 in which a hole 55 is made. A clamping element 56 is engaged in the latter, the truncated tip of which is 57 bears against the bottom 27 of the profile 26. Advantageously, the clamping element 56 is a screw and, consequently, the hole 55 is a tapped hole. The rear face 41 has a clearance 58 so that the clamping element 56 can protrude. Thus, the locking means of the locking device 34 are constituted by the screw 56. In fact, by actuating the latter, there is a tendency to give the support 35 a certain rotation relative to the lower shoulder 43 of the boss 42 so that the rear face 41 of the support 35 is pressed against the bottom 27 of the profile 26 while the front face 48 is pressed against the vertical bosses 51, 52 of the two wings 24, 25 of the profile 26 and that two zones of opposite tightening. Thus, the bottom 27 of the profile 26 and the two vertical bosses 51, 52 of the two wings 24, 25 of the profile 26 constitute other means of complementarity of the sliding leaf 1 making it possible to hold the locking device 34 in its position. Is practiced in the body 59 of the support 35 a vertical groove 60 in which is disposed the locking lever 36. The latter can pivot around an axis 61 whose ends 62, 63 are engaged in orifices 64, 65 made in the faces 66, 67 of the body 59.

Le levier de condamnation 36 comporte à son extrémité inférieure 68 un bras de rappel 69 basculant dans la saignée verticale 60. L'extrémité inférieure 70 de ce bras de rappel 69 comporte sur sa face externe 71 un téton 72 sur lequel est enfilée l'extrémité 73 d'un élément élastique 74 dont l'autre extrémité 75 est logée dans un trou borgne 76 réalisé dans le corps 59 du support 35 et débouchant perpendiculairement dans la saignée verticale 60. Cet élément élastique 74 est en position précontrainte entre le fond 77 du trou borgne 76 et la face externe 71 du bras de rappel 69.The locking lever 36 has at its lower end 68 a return arm 69 rocking in the vertical groove 60. The lower end 70 of this return arm 69 has on its external face 71 a stud 72 on which the end is threaded 73 of an elastic element 74, the other end 75 of which is housed in a blind hole 76 produced in the body 59 of the support 35 and opening perpendicularly into the vertical groove 60. This elastic element 74 is in the prestressed position between the bottom 77 of the blind hole 76 and the external face 71 of the return arm 69.

Par ailleurs, le levier de condamnation 36 comporte à son extrémité supérieure 78 un bras de commande 79 situé pratiquement dans le prolongement du bras de rappel 69. Ce bras de commande 79 présente à son extrémité supérieure 80 un chant-butée 81 contre lequel prend appui le chant inférieur 82 du crochet 23 du pêne à crochet 22. Par ailleurs, le bras de commande 79 comporte une cambrure 83 située entre le chant-butée 81 et l'extrémité supérieure 78 du levier de condamnation 36. Cette cambrure 83 permet d'escamoter le chant-butée 81 entre les deux ailes 24, 25 du profilé 26 de l'ouvrant coulissant 1.Furthermore, the locking lever 36 has at its upper end 78 a control arm 79 located practically in the extension of the return arm 69. This control arm 79 has at its upper end 80 a stop-song 81 against which is supported the lower edge 82 of the hook 23 of the hook bolt 22. Furthermore, the control arm 79 has a camber 83 located between the edge-stop 81 and the upper end 78 of the locking lever 36. This camber 83 makes it possible to retract the edge-stop 81 between the two wings 24, 25 of the profile 26 of the sliding leaf 1.

En outre, le corps 59 du support 35 se rétrécie vers son chant vertical 84 pour faciliter sa pénétration entre les deux ailes 31, 32 du profilé 33 du dormant 30 lorsque la ferrure est en position verrouillée.In addition, the body 59 of the support 35 narrows towards its vertical edge 84 to facilitate its penetration between the two wings 31, 32 of the section 33 of the frame 30 when the fitting is in the locked position.

Le fonctionnement est le suivant :

  • On considère l'ouvrant en position verrouillée tel que représenté dans les figures 1 et 2. Par l'intermédiaire de la poignée 19, on relève le coulisseau 18 et, par voie de conséquence, le pêne à crochet 22. De ce fait,le crochet (23) se désengage de la partie active 85 de la gâche 29. Puis, on ouvre l'ouvrant coulissant 1 de la fenêtre, porte ou analogue.
The operation is as follows:
  • The opening is considered in the locked position as shown in FIGS. 1 and 2. By means of the handle 19, the slide 18 is raised and, consequently, the hook bolt 22. As a result, the hook (23) disengages from the active part 85 of the keeper 29. Then, the sliding opening 1 of the window, door or the like is opened.

Au cours de ce coulissement de l'ouvrant, l'élément élastique 74 se détend et agit sur le bras de rappel 69 en provoquant la rotation du levier de condamnation 36 de sorte que le bras de commande 79 décrit un arc de cercle dans le sens d'avance des aiguilles d'une montre limité par le contact entre le bras de rappel 69 et la paroi arrière 86 de la saignée verticale 60. Au cours de cette rotation, le chant-butée 81 vient se placer sous le chant inférieur 82 du crochet 23 du pêne à crochet 22. Il devient, de ce fait, impossible de rabaisser le coulisseau 18 et le pêne à crochet 22 est maintenu en face de l'ouverture 87 de la gâche 29 tel que visible dans la figure 3.During this sliding of the opening, the elastic element 74 expands and acts on the return arm 69 by causing the rotation of the locking lever 36 so that the control arm 79 describes an arc of a circle in the direction in advance of the hands of a watch limited by the contact between the return arm 69 and the rear wall 86 of the vertical groove 60. During this rotation, the edge-stop 81 comes to be placed under the bottom edge 82 of the hook 23 of the hook bolt 22. It therefore becomes impossible to lower the slider 18 and the hook bolt 22 is held opposite the opening 87 of the keeper 29 as seen in FIG. 3.

En fermant l'ouvrant coulissant 1, la face avant 88 de la gâche 29 appuie sur l'extrémité supérieure 80 du bras de commande 79 en provoquant la rotation, en sens inverse du précédent, du levier de condamnation 36 jusqu'à ce que la cambrure 83 du bras de commande 79 soit en contact avec ladite face avant 88 de la gâche 29. Simultanément, le bras de rappel 69 décrit un arc de cercle et comprime l'élément élastique 74. Le chant-butée 81 étant situé dans le dégagement 89 du pêne à crochet 22 et le crochet 23 étant à l'intérieur de la gâche 29, il devient possible d'actionner le coulisseau 18 pour l'amener à la position de verrouillage tel que visible dans la figure 2. Ainsi, le dispositif de condamnation 34 vient se placer sous la gâche 29 et il devient impossible de soulever l'ouvrant coulissant 1 après fermeture et verrouillage.By closing the sliding sash 1, the front face 88 of the keeper 29 presses on the upper end 80 of the control arm 79 by causing the rotation, in opposite direction of the previous one, of the locking lever 36 until the camber 83 of the control arm 79 is in contact with said front face 88 of the keeper 29. Simultaneously, the return arm 69 describes an arc of a circle and compresses the elastic element 74. The edge-stop 81 being located in the clearance 89 of the hook bolt 22 and the hook 23 being inside the keeper 29, it becomes possible to actuate the slider 18 to bring it to the locking position as shown in FIG. 2. Thus, the device 34 is placed under the keeper 29 and it becomes impossible to lift the sliding leaf 1 after closing and locking.
