Description

L'invention a trait à une crémone automatique à double action comportant deux tringles tenues engagées en position de verrouillage dans un jeu de gâches, un boîtier, un jeu de leviers angulaires, articulés à leurs sommets et logés dans le boîtier de la crémone, et une poignée de manoeuvre et de commande rappelée en position de repos par un élément élastique et pourvue à l'une de ses extrémités d'une tige de commande munie d'un ergot qui, pour le verrouillage, exerce son action transversalement sur les tringles reliées chacune à l'extrémité de l'une des branches des leviers angulaires et qui, pour le déverrouillage, s'engage dans une lumière réalisée à l'extrémité de l'autre branche des leviers angulaires.The invention relates to a double action automatic cremone bolt comprising two rods held engaged in the locked position in a set of strikes, a casing, a set of angular levers, articulated at their apices and housed in the casing of the cremone bolt, and an operating and control handle returned to the rest position by an elastic element and provided at one of its ends with a control rod provided with a lug which, for locking, exerts its action transversely on the connected rods each at the end of one of the branches of the angular levers and which, for unlocking, engages in a slot made at the end of the other branch of the angular levers.

On connaît déjà, par le document DE-A-2730407, une crémone automatique à double action comportant deux tringles tenues engagées en position de verrouillage dans un jeu de gâches par des éléments élastiques de rappel et étant retirées dans une position de déverrouillage par un jeu de leviers angulaires articulés à leurs sommets dans le boîtier de la crémone et reliés chacun, par l'extrémité de l'une de ses branches, à une des tringles, ces leviers angulaires comportant, à l'extrémité de leur autre branche, une lumière dans laquelle s'engage un ergot d'au moins une tige de commande exerçant son action transversalement aux tringles et étant solidaire d'une poignée de manoeuvre et de commande rappelée en position de repos par un effet élastique.We already know, from document DE-A-2730407, a double action automatic cremone bolt comprising two rods held engaged in the locked position in a strike set by elastic return elements and being withdrawn in an unlocked position by a play angular levers articulated at their tops in the cremone bolt case and each connected, by the end of one of its branches, to one of the rods, these angular levers comprising, at the end of their other branch, a light in which engages a lug of at least one control rod exerting its action transverse to the rods and being secured to an operating and control handle returned to the rest position by an elastic effect.

Toutefois, cette crémone connue nécessite une poignée en forme de barre allongée permettant une certaine flexion pour pouvoir exercer une traction sur la tige de commande agissant sur les leviers angulaires pour retirer les tringles de teurs gâches.However, this known lever requires a handle in the form of an elongated bar allowing a certain flexion in order to be able to exert a traction on the control rod acting on the angular levers to remove the rods from the striker pins.

Outre l'encombrement et le coût de cette poignée, le mécanisme de la crémone, transmettant aux tringles l'impulsion donnée à la poignée, relie cette dernière aux tringles de façon constante. De ce fait, lors de la fermeture de l'ouvrant, les tringles s'enclenchent difficilement dans leurs gâches. En effet, pour fermer l'ouvrant, il faut exercer une poussée sur la poignée. Cette poussée est transmise aux tringles par l'intermédiaire du mécanisme de la crémone et elle s'oppose à tout recul des tringles.In addition to the size and cost of this handle, the mechanism of the lever, transmitting to the rods the impulse given to the handle, connects the latter to the rods in a constant manner. Therefore, when closing the door, the rods are difficult to engage in their keepers. Indeed, to close the opening, it is necessary to exert a push on the handle. This thrust is transmitted to the rods via the mechanism of the lever and it opposes any retreat of the rods.

Cependant, ce recul est indispensable pour permettre aux tringles de rentrer dans leur gâche respective. Par conséquent, il faut lâcher la poignée pendant la dernière phase de la fermeture de l'ouvrant et agir directement sur ce dernier pour provoquer le recul des tringles pour permettre leur enclenchement dans les gâches et conférer ainsi à la crémone sa position de verrouillage.However, this retreat is essential to allow the rods to return to their respective keepers. Consequently, it is necessary to let go of the handle during the last phase of the closing of the opening and act directly on the latter to cause the retraction of the rods to allow their engagement in the strikes and thus to give the cremone bolt its locking position.

La présente invention a pour but de remédier à ces inconvénients et de concevoir une crémone automatique pouvant équiper indifféremment des ouvrants vers l'extérieur comme des ouvrants vers l'intérieur, tout en permettant une fermeture facile et sûre de l'ouvrant. L'invention, telle qu'elle est caractérisée dans la revendication 1, permet de résoudre en prévoyant une crémone automatique à double action comportant deux tringles tenues engagées en position de verrouillage dans un jeu de gâches, un boîtier, un jeu de leviers angulaires, articulés à leurs sommets et logés dans le boîtier de la crémone, et une poignée de manoeuvre et de commande rappelée en position de repos par un élément élastique et pourvue à l'une de ses extrémités d'une tige de commande munie d'un ergot qui, pour le verrouillage, exerce son action transversalement sur les tringles reliées chacune à l'extrémité de l'une des branches des leviers angulaires et qui, pour le déverrouillage, s'engage dans une lumière réalisée à l'extrémité de l'autre branche des leviers angulaires, caractérisée en ce que la lumière de l'autre branche des leviers angulaires est disposée sur le bord de ladite branche de façon à former un dégagement ouvert dont le fond constitue un chant d'attaque coopérant, lors du déverrouillage de la crémone, avec l'ergot de la tige de commande.The object of the present invention is to remedy these drawbacks and to design an automatic cremone bolt capable of equipping either outward opening or inward opening, while allowing easy and secure closing of the opening. The invention, as characterized in claim 1, makes it possible to solve by providing an automatic double-action lever comprising two rods held engaged in the locked position in a set of strikes, a housing, a set of angular levers, articulated at their tops and housed in the cremone bolt housing, and an operating and control handle returned to the rest position by an elastic element and provided at one of its ends with a control rod provided with a lug which, for locking, exerts its action transversely on the rods each connected to the end of one of the branches of the angular levers and which, for unlocking, engages in a light produced at the end of the other branch of the angular levers, characterized in that the lumen of the other branch of the angular levers is arranged on the edge of said branch so as to form an open clearance, the bottom of which constitutes a co-operative edge ant, when unlocking the cremone bolt, with the lug on the control rod.

Par la mise en oeuvre de ces caractéristiques, il est désormais possible non seulement de pouvoir agir sur la poignée de manoeuvre et de commande pour retirer les tringles hors de leurs gâches lors de l'ouverture de l'ouvrant, mais aussi de pouvoir exercer une action sur ladite poignée pour la fermeture de l'ouvrant sans que les tringles soient gênées dans leur mouvement d'enclenchement dans les gâches. En effet, pour l'ouverture, l'ergot de la tige de commande coopère avec le chant d'attaque des leviers angulaires pour retirer les tringles et permettre l'ouverture de l'ouvrant, tandis qu'au moment de la fermeture de l'ouvrant, aucune coopération entre ces éléments ne gêne le bon enclenchement des tringles dans leurs gâches.By implementing these characteristics, it is now possible not only to be able to act on the operating and control handle to remove the rods from their keepers when the opening is opened, but also to be able to exert a action on said handle for closing the opening without the rods being hampered in their engagement movement in the strikes. Indeed, for the opening, the lug of the control rod cooperates with the leading edge of the angular levers to remove the rods and allow the opening of the opening, while at the time of closing of the opening, no cooperation between these elements hinders the proper engagement of the rods in their keepers.

En raison du désengagement de l'ergot de la tige de commande hors de la lumière de l'équerre angulaire, il est possible que l'action de l'ergot comporte une course à vide supplémentaire délimitée par le chant d'attaque et une des parois latérales du boîtier.Due to the disengagement of the lug from the control rod out of the light of the angle bracket, it is possible that the action of the lug includes an additional free stroke delimited by the leading edge and one of the side walls of the housing.

Comme exposé ci-dessous, l'invention, par cette course à vide, crée les conditions permettant de prévoir une conception assurant une fermeture certaine de l'ouvrant palliant à une défaillance éventuelle des moyens de rappel élastique des tringles ou que, pour une raison quelconque, la force nécessaire à l'introduction des tringles dans leurs gâches est supérieure à celle fournie par lesdits moyens de rappel élastique des tringles.As explained below, the invention, by this idle stroke, creates the conditions making it possible to provide a design ensuring a certain closure of the opening window compensating for a possible failure of the elastic return means of the rods or that, for a reason arbitrary, the force required to introduce the rods into their keepers is greater than that provided by said elastic return means of the rods.

La crémone automatique, objet de la présente invention, est d'une manoeuvre plus facile et peut s'employer indifféremment à droite ou à gauche après simple inversion, lorsque la poignée de manoeuvre et de commande est un levier solidaire du boîtier et articulé sur un axe parallèle aux tringles et comportant, opposée au bras du levier, la tige de commande pourvue de l'ergot.The automatic lever, object of the present invention, is easier to operate and can be used either on the right or on the left after simple reversal, when the operating and control handle is a lever secured to the housing and articulated on a axis parallel to the rods and comprising, opposite the lever arm, the control rod provided with the lug.

Le fonctionnement plus facile de la crémone automatique est encore accentué par une mesure prévoyant que la poignée de manoeuvre et de commande comporte deux tiges de commande parallèles et espacées agissant chacune par son ergot sur le chant d'attaque d'un levier angulaire disposé sur son champ d'action.The easier operation of the automatic lever is further accentuated by a measure providing that the operating and control handle has two parallel and spaced control rods each acting by its lug on the song of attack of an angular lever arranged on its field of action.

Cette dernière mesure est avantageusement complétée par le fait que le chant d'attaque de chaque levier angulaire comporte une courbure concave favorisant le glissement de l'ergot sur le chant d'attaque et que chaque tringle comporte à son extrémité reliée au levier angulaire un coulisseau guidé dans le boîtier et étant en prise avec le levier angulaire par un élément de liaison engagé dans une lumière.This last measure is advantageously supplemented by the fact that the leading edge of each angular lever has a concave curvature favoring the sliding of the lug on the leading edge and that each rod has at its end connected to the angular lever a slide guided in the housing and being engaged with the angular lever by a connecting element engaged in a light.

Cette conception particulière prévue par l'invention permet de concevoir une crémone automatique avec des tringles indépendantes, ce qui facilite le stockage et la mise à dimension des crémones. Selon l'invention, chaque coulisseau comporte, à cet effet, un élément de liaison avec une tringle.This particular design provided by the invention makes it possible to design an automatic cremone bolt with independent rods, which facilitates the storage and the dimensioning of the cremones. According to the invention, each slide comprises, for this purpose, a connecting element with a rod.

Pour assurer la fermeture certaine de l'ouvrant, l'invention prévoit que chaque tringle comporte à son extrémité reliée au levier angulaire une rampe disposée en travers du chemin parcouru par l'ergot respectif pendant la course à vide de la poignée.To ensure certain closure of the opening, the invention provides that each rod has at its end connected to the angular lever a ramp arranged across the path traveled by the respective lug during the empty stroke of the handle.

Par suite de la coopération entre la rampe et l'ergot respectif, les tringles sont toujours entièrement poussées en position de verrouillage, même lorsqu'un voilage de l'ouvrant ou autre empêchement fait échec au rappel élastique automatique des tringles. Les ergots, solidaires de la poignée de manoeuvre et de commande, glissent le long des rampes pendant la course à vide de la poignée et poussent les tringles dans leurs positions de verrouillage.As a result of the cooperation between the ramp and the respective lug, the rods are always fully pushed into the locking position, even when the opening of the sash or other obstacle prevents the automatic elastic return of the rods. The lugs, integral with the operating and control handle, slide along the ramps during the idle stroke of the handle and push the rods into their locked positions.

D'autres caractéristiques et avantages de l'invention résultent de la description d'un exemple de réalisation de crémone automatique pour un ouvrant à ouverture vers l'extérieur.Other characteristics and advantages of the invention result from the description of an exemplary embodiment of an automatic cremone bolt for an opening opening towards the outside.

Ces leviers angulaires 3, 4 peuvent pivoter autour d'un axe 7, 8 solidaire de la face interne 9 de l'une des parois 10 du boîtier 2. Cet axe 7, 8 traverse un orifice 11,12 réalisé dans le sommet 13,14 desdits leviers angulaires 3, 4. Ces derniers comportent une première branche 15,16 dans laquelle est réalisée une lumière 17,18 dans laquelle peut coulisser un téton 19, 20.The mechanism comprises a set of angular levers 3, 4 connected by a link 5, 6 to the rods. These angular levers 3, 4 can pivot around an axis 7, 8 secured to the internal face 9 of one of the walls 10 of the housing 2. This axis 7, 8 passes through an orifice 11, 12 produced in the apex 13, 14 of said angular levers 3, 4. The latter comprise a first branch 15, 16 in which a hole 17, 18 is produced in which a stud 19, 20 can slide.

Selon un premier mode de réalisation, ce téton 19,20 est solidaire de l'une des faces 21 de l'extrémité des tringles traversant des lumières réalisées dans les chants 22, 23 du boîtier 2.According to a first embodiment, this stud 19,20 is integral with one of the faces 21 of the end of the rods passing through lights made in the edges 22, 23 of the housing 2.

Selon un autre mode de réalisation, ce téton 19, 20 est solidaire de l'une des faces 21 d'un coulisseau 24, 25 se déplaçant dans le boîtier 2 et guidé par les parois latérales 26,27 de ce dernier. Dans ce cas, on pourvoit l'autre face 28 des coulisseaux 24, 25 d'un élément de liaison 29, 30 traversant une lumière oblongue 31 réalisée dans l'autre paroi 32 du boîtier 2. Cet élément de liaison 29, 30 fait saillie par rapport à la face externe 33 de la paroi 32 du boîtier 2. Avantageusement, cet élément de liaison 29, 30 a la forme d'un axe sur lequel est enfilée l'extrémité de l'une des tringles. De ce fait, il est possible de séparer le boîtier 2 des tringles, ce qui facilite le stockage de la crémone automatique 1. Par ailleurs, il est possible d'ajuster la longueur des tringles en fonction de la hauteur de l'ouvrant.According to another embodiment, this stud 19, 20 is integral with one of the faces 21 of a slide 24, 25 moving in the housing 2 and guided by the side walls 26, 27 of the latter. In this case, the other face 28 of the slides 24, 25 is provided with a connecting element 29, 30 passing through an oblong opening 31 made in the other wall 32 of the housing 2. This connecting element 29, 30 projects relative to the external face 33 of the wall 32 of the housing 2. Advantageously, this connecting element 29, 30 has the shape of an axis on which the end of one of the rods is threaded. Therefore, it is possible to separate the housing 2 from the rods, which facilitates the storage of the automatic locking rod 1. Furthermore, it is possible to adjust the length of the rods according to the height of the opening.

Les leviers angulaires 3, 4 comportent une seconde branche 34, 35 présentant également une lumière 36, 37. Cependant, cette lumière 36, 37 est disposée sur le bord 38, 39 de la seconde branche 34, 35 de sorte que l'on obtient un dégagement ouvert 40, 41. Le fond de ce dégagement ouvert 40, 41 constitue un chant d'attaque 42, 43 pour des moyens permettant d'actionner lesdits leviers angulaires 3, 4.The angular levers 3, 4 comprise a second branch 34, 35 also having a light 36, 37. However, this light 36, 37 is arranged on the edge 38, 39 of the second branch 34, 35 so that one obtains an open clearance 40, 41. The bottom of this open clearance 40, 41 constitutes a leading edge 42, 43 for means making it possible to actuate said angular levers 3, 4.

Un de ces moyens est un ergot 44 disposé à l'extrémité 45 d'au moins une tige de commande 46 exerçant son action transversalement aux tringles. Cette extrémité 46 pourvue de l'ergot 44 se déplace dans une lumière 47 réalisée dans la paroi 10 du boîtier 2. En phase d'ouverture, cet ergot 44 exerce une poussée sur le chant d'attaque 42, 43 du dégagement ouvert 40,41 de la seconde branche 34, 35 des leviers angulaires 3, 4. Pour favoriser le glissement de l'ergot 44 sur le chant d'attaque 42, 43, le chant d'attaque42,43 comporte une courbure concave 48, 49.One of these means is a lug 44 disposed at the end 45 of at least one control rod 46 exerting its action transversely to the rods. This end 46 provided with the lug 44 moves in a slot 47 produced in the wall 10 of the housing 2. In the opening phase, this lug 44 exerts a push on the leading edge 42, 43 of the open clearance 40, 41 of the second branch 34, 35 of the angular levers 3, 4. To promote the sliding of the lug 44 on the leading edge 42, 43, the leading edge42,43 has a concave curvature 48, 49.

La tige de commande 46 est solidaire d'une extrémité 50 d'une poignée de manoeuvre et de commande 51. Cette poignée de manoeuvre et de commande 51 peut pivoter autour d'un axe 52 maintenu par une chape 53 solidaire de la face externe 54 de la paroi 10 du boîtier 2. En actionnant la poignée de manoeuvre et de commande 51, celle-ci pivote autour de l'axe 52 en provoquant également la rotation de la tige de commande 46 autour du même axe 52. Ladite poignée de manoeuvre et de commande 51 est rappelée en position de repos par un élément élastique 55. Ce dernier peut être un ressort enroulé sur l'axe 52 dont une des branches 56 est fixe et dont l'autre branche 57 prend appui contre le chant 58 de la tige de commande 46.The control rod 46 is integral with one end 50 of an operating and control handle 51. This operating and control handle 51 can pivot around an axis 52 held by a yoke 53 secured to the external face 54 of the wall 10 of the housing 2. By actuating the operating and control handle 51, the latter pivots around the axis 52 while also causing the control rod 46 to rotate around of the same axis 52. Said operating and control handle 51 is returned to the rest position by an elastic element 55. The latter may be a spring wound on the axis 52 of which one of the branches 56 is fixed and of which the other branch 57 bears against the edge 58 of the control rod 46.

La tige de commande 46 comporte un cliquet de positionnement 59 coulissant dans un moyen 60 et rappelé en position d'action par un élément élastique 61. Comme visible dans la figure 6, le cliquet de positionnement 59 peut occuper trois positions 62,63,64, l'une 62 correspondant à la position 65 de la poignée de manoeuvre et de commande 51 poussée à fond pour l'ouverture de l'ouvrant, l'autre 64 correspondant à la position de repos 66 de la poignée de manoeuvre et de commande 51 et, dans la position intermédiaire 63, le cliquet de positionnement 59 retient la poignée de manoeuvre et de commande 51 en position intermédiaire 67 pour la fermeture de l'ouvrant.The control rod 46 comprises a positioning pawl 59 sliding in a means 60 and returned to the action position by an elastic element 61. As visible in FIG. 6, the positioning pawl 59 can occupy three positions 62,63,64 , one 62 corresponding to the position 65 of the operating and control handle 51 pushed fully to the opening of the opening, the other 64 corresponding to the rest position 66 of the operating and control handle 51 and, in the intermediate position 63, the positioning pawl 59 retains the operating and control handle 51 in the intermediate position 67 for closing the opening.

Avantageusement, la poignée de manoeuvre et de commande 51 comporte deux tiges de commande 46 parallèles et espacées, agissant chacune par son ergot 44 sur le chant d'attaque 42, 43 d'un levier angulaire 3,4 disposé dans son champ d'action.Advantageously, the operating and control handle 51 comprises two parallel and spaced control rods 46, each acting by its lug 44 on the leading edge 42, 43 of an angular lever 3, 4 disposed in its field of action .

Le fonctionnement de la crémone automatique 1 conforme à l'invention est le suivant:The operation of the automatic cremone bolt 1 according to the invention is as follows:

On considère que la crémone automatique 1 est en position verrouillée. L'ergot 44 de la tige de commande 46 prend appui contre la face interne de la paroi latérale 27 du boîtier 2, la poignée de manoeuvre et de commande 51 se trouve à la position 66 alors que le cliquet de positionnement 59 se trouve en 64 (voir figures 1 et 5). On actionne la poignée de manoeuvre et de commande 51 pour la mettre en position intermédiaire 67. Cette poignée de manoeuvre et de commande 51 parcourt une course à vide 68 correspondant à une course à vide 69 effectuée par les ergots 44 qui viennent se placer contre les chants d'attaque 42, 43 des leviers angulaires 3, 4 (voir figures 2 et 5).It is considered that the automatic lever 1 is in the locked position. The lug 44 of the control rod 46 bears against the internal face of the side wall 27 of the housing 2, the operating and control handle 51 is in position 66 while the positioning pawl 59 is in 64 (see figures 1 and 5). The operating and control handle 51 is actuated to put it in the intermediate position 67. This operating and control handle 51 travels through an idle stroke 68 corresponding to an idle stroke 69 effected by the pins 44 which are placed against the leading edges 42, 43 of the angular levers 3, 4 (see Figures 2 and 5).

En continuant à pousser la poignée de manoeuvre et de commande 51, les ergots 44 actionnés par cette dernière exercent une poussée sur les chants d'attaque 42, 43 en provoquant la rotation des leviers angulaires 3, 4 et la compression de l'élément élastique 55. Suite à cette rotation des leviers angulaires 3, 4, la première branche 15, 16, par l'intermédiaire de la coopération des lumières 17, 18 avec les tétons 19, 20, provoque le rapprochement des coulisseaux 24, 25 et, par voie de conséquence, par le recul des tringles, le déverrouillage de l'ouvrant.By continuing to push the operating and control handle 51, the lugs 44 actuated by the latter exert a push on the leading edges 42, 43 by causing the rotation of the angular levers 3, 4 and the compression of the elastic element 55. Following this rotation of the angular levers 3, 4, the first branch 15, 16, by means of the cooperation of the slots 17, 18 with the pins 19, 20, brings the sliders 24, 25 and, by consequently, by the retraction of the rods, the unlocking of the opening.

En fin de cette course supplémentaire 70, la poignée de manoeuvre et de commande 51 occupe la position 65 et le cliquet de postionnement 59 la position 62 (voir figures 3 et 5).At the end of this additional stroke 70, the operating and control handle 51 occupies position 65 and the positioning pawl 59 position 62 (see FIGS. 3 and 5).

En relâchant la poignée de manoeuvre et de commande 51, celle-ci sous l'effet de l'élément élastique 55 revient à sa position 67 et le cliquet de positionnement 59 se déplace et vient à sa position intermédiaire 63. Sous la poussée de l'élément élastique 61, la tête 71 dudit cliquet 59 s'engage dans un orifice d'arrêt 72 réalisé dans le boîtier 2 en retenant la poignée de manoeuvre de commande 51 en position intermédiaire 67 pour la fermeture de l'ouvrant. Pendant ce temps, l'ergot 44 parcourt en sens inverse la course à vide 69 (voir figures 4 et 5). Cependant, il se peut que, par suite d'un voilage de l'ouvrant, d'une détérioration des éléments élastiques de rappel des tringles ou tout autre empêchement, il soit fait échec au rappel automatique des tringles.By releasing the operating and control handle 51, the latter under the effect of the elastic element 55 returns to its position 67 and the positioning pawl 59 moves and comes to its intermediate position 63. Under the thrust of the 'elastic element 61, the head 71 of said pawl 59 engages in a stop orifice 72 made in the housing 2 while retaining the control operating handle 51 in the intermediate position 67 for closing the opening. During this time, the lug 44 traverses in the opposite direction the idle stroke 69 (see FIGS. 4 and 5). However, it may be that, as a result of the opening of the opening, a deterioration of the elastic return elements of the rods or any other impediment, the automatic recall of the rods will be frustrated.

A cet effet, on pourvoit soit chaque extrémité de tringle reliée au levier angulaire 3, 4, soit chaque coulisseau 24,25 d'une rampe 73, 74 faisant saillie par rapport à la face 21 de ces coulisseaux 24, 25. Cette rampe 73, 74 est disposée en travers du chemin parcouru par l'ergot respectif 44 pendant la course à vide de la poignée de manoeuvre et de la commande 51. En ramenant cette dernière de la position 67 à la position 66, l'ergot 44 glisse le long de la rampe 73, 74 et repousse les coulisseaux 24, 25. Ce mouvement est transmis par les éléments de liaison 28, 30 aux tringles. De ce fait, ces dernières sont repoussées dans leurs positions de verrouillage, donc engagées dans leur gâche respective.To this end, either each end of the rod connected to the angular lever 3, 4 is provided, or each slide 24.25 of a ramp 73, 74 projecting relative to the face 21 of these slides 24, 25. This ramp 73 , 74 is arranged across the path traveled by the respective lug 44 during the idle stroke of the operating handle and of the control 51. By bringing the latter from position 67 to position 66, lug 44 slides the along the ramp 73, 74 and pushes the slides 24, 25. This movement is transmitted by the connecting elements 28, 30 to the rods. As a result, the latter are pushed back into their locking positions, therefore engaged in their respective keepers.
