Description

L'invention concerne une crémone, en particulier une crémone-serrure pour porte, porte-fenêtre ou analogue comportant au moins une tringle de manoeuvre pourvue d'au moins un élément de verrouillage pénétrant dans une gâche solidaire du dormant; un élément de blocage de la tringle de manoeuvre en position déverrouillée, ledit élément de blocage étant rappelé élastiquement dans la position de maintien déverrouillée de la tringle de manoeuvre et coopérant avec des moyens de déblocage solidaires du dormant; des moyens de rappel élastique permettant de faire passer la tringle de manoeuvre de la position déverrouillée à la position verrouillée: et un mécanisme de commande comprenant, d'une part, un fouillot permettant la manoeuvre de la tringle et, d'autre part, un pêne horizontal déplaçable au moyen d'un barillet.The invention relates to a cremone bolt, in particular a cremone bolt for a door, French window or the like comprising at least one operating rod provided with at least one locking element penetrating into a keeper fixed to the frame; a locking element of the operating rod in the unlocked position, said locking element being resiliently returned to the unlocked holding position of the operating rod and cooperating with unlocking means integral with the frame; elastic return means making it possible to move the operating rod from the unlocked position to the locked position: and a control mechanism comprising, on the one hand, a follower allowing the rod to operate and, on the other hand, a horizontal bolt movable by means of a barrel.

On connaît déjà, par le brevet allemand no. 1 062 143, une crémone-serrure ayant les caractéristiques énoncées dans le préambule de la revendication 1. La tringle de manoeuvre de cette crémone-serrure est automatiquement rappelée en position de verrouillage par l'intermédiaire d'un élément élastique. Pour maintenir ladite tringle de manoeuvre en position de déverrouillage, cette crémone-serrure est pourvue d'un mécanisme de blocage comportant un doigt faisant saillie par rapport à la face visible de la têtière de la crémone-serrure. En fermant l'ouvrant, ce doigt est repoussé et il libère le mécanisme de blocage et, par voie de conséquence, la tringle de manoeuvre qui est aussitôt rappelée en position de verrouillage.We already know, by German patent no. 1 062 143, a locking lever having the characteristics set out in the preamble of claim 1. The operating rod of this locking lever is automatically returned to the locking position by means of an elastic element. To maintain said operating rod in the unlocked position, this lock-bolt is provided with a locking mechanism comprising a finger projecting from the visible face of the headrest of the lock-bolt. By closing the door, this finger is pushed back and it releases the locking mechanism and, consequently, the operating rod which is immediately returned to the locking position.

Toutefois, lors de la fermeture de l'ouvrant, il y a risque de blessure par suite d'un rappel brusque de la poignée lorsque les tringles sont poussées par le ressort dans leurs positions de verrouillage. Ce brusque rappel de la poignée est provoqué par le fait que la poignée, par l'intermédiaire du fouillot, est reliée aux tringles et suit tout mouvement de ces dernières. Par ailleurs, en cas de fatigue du ressort de rappel agissant sur la tringle de manoeuvre, la crémone-serrure ne peut pas être amenée en position de verrouillage et l'ouverture de la porte ou de la porte-fenêtre ne peut pas être condamnée.However, when the opening is closed, there is a risk of injury due to an abrupt return of the handle when the rods are pushed by the spring into their locked positions. This abrupt recall of the handle is caused by the fact that the handle, via the follower, is connected to the rods and follows any movement of the latter. Furthermore, in the event of fatigue of the return spring acting on the operating rod, the lock-bolt cannot be brought into the locking position and the opening of the door or the French window cannot be prevented.

La présente invention a pour but de remédier à ces inconvénients. L'invention, telle qu'elle est caractérisée dans les revendications, résout ces problèmes en créant une crémone-serrure présentant une poignée rappelée automatiquement en position de repos sans action sur la tringle de manoeuvre et, d'autre part, une sécurité totale d'un verrouillage automatique lors de la fermeture et/ou de la condamnation de l'ouvrant.The present invention aims to remedy these drawbacks. The invention, as characterized in the claims, solves these problems by creating a locking lever having a handle automatically returned to the rest position without action on the operating rod and, on the other hand, total security of '' an automatic locking when the door is closed and / or locked.

Les avantages obtenus grâce à l'invention consistent essentiellement en ce que, malgré une fatigue éventuelle des moyens de rappel de la tringle de manoeuvre en position de verrouillage, la crémone-serrure est amenée en position de verrouillage lors de fa condamnation de la porte, porte-fenêtre ou analogue. Parallèlement, l'invention permet d'obtenir une standardisation des garnitures de portes. Du fait que la poignée, une fois abaissée, revient automatiquement à sa position de repos, on peut utiliser les garnitures de portes courantes.The advantages obtained by virtue of the invention essentially consist in that, despite possible fatigue of the return means of the operating rod in the locked position, the locking lever is brought into the locked position when the door is locked, French window or the like. At the same time, the invention allows standardization of door fittings. Since the handle, once lowered, automatically returns to its rest position, standard door fittings can be used.

On se réfère aux figures 1 et 2.We refer to Figures 1 and 2.

La crémone-serrure 1 comporte un boîtier 2 constitué de deux plaques parallèles 3, 4 (voir figure 4) renfermant les différentes pièces constituant le mécanisme 5 et provoquant le déplacement d'au moins une tringle de manoeuvre 6.The lock-bolt 1 comprises a box 2 consisting of two parallel plates 3, 4 (see FIG. 4) containing the various parts constituting the mechanism 5 and causing the displacement of at least one operating rod 6.

Le mécanisme 5 comporte un fouillot 7 présentant un carré de manoeuvre 8 dans lequel est engagé l'axe d'une poignée de manoeuvre (non représentée). Le fouillot 7 est pourvu d'un doigt 9 muni d'un téton 10 sur lequel prend appui l'extrémité 11 d'un élément élastique 12 telle qu'une lame de ressort dont l'autre extrémité 13 s'enroule en forme de spirale autour d'un axe 14. En actionnant la poignée, on provoque une rotation du fouillot 7 et le téton 10 sollicite l'élément élastique 12 en poussant l'extrémité 11. En relâchant la poignée, l'élément élastique 12 repousse le téton 10 et provoque une rotation du fouillot 7 en sens inverse. De ce fait, la poignée revient automatiquement en position de repos.The mechanism 5 comprises a follower 7 having an operating square 8 in which is engaged the axis of an operating handle (not shown). The follower 7 is provided with a finger 9 provided with a stud 10 on which the end 11 bears on an elastic element 12 such as a leaf spring whose other end 13 is wound in the form of a spiral around an axis 14. By actuating the handle, the follower 7 is rotated and the stud 10 urges the elastic element 12 by pushing the end 11. By releasing the handle, the elastic element 12 pushes back the stud 10 and causes rotation of the follower 7 in the opposite direction. As a result, the handle automatically returns to the rest position.

Le fouillot 7 comporte également un second doigt de commande 15. Celui-ci agit, en phase de déverrouillage, sur un axe 16 solidaire d'un talon 17 de la tringle de manoeuvre 6. Les extrémités 18, 19 de cet axe 16, soumis à un déplacement vertical, se dépla- centdans des lumières verticales 20 pratiquées dans les deux plaques parallèles 3, 4 du boîtier 2. Le talon 17 présente à ses extrémités supérieure 21 et inférieure 22 un téton 23, 24 s'engageant dans dés trous 25, 26 réalisés dans la tringle de manoeuvre 6, ce qui assure la liaison entre la tringle de manoeuvre 6 et le talon 17. Ce dernier comporte une denture 27 coopérant avec un dispositif 28 de rappel automatique en position de verrouillage de la tringle 6.The follower 7 also includes a second control finger 15. This acts, in the unlocking phase, on an axis 16 secured to a heel 17 of the operating rod 6. The ends 18, 19 of this axis 16, subjected when moving vertically, move in vertical openings 20 made in the two parallel plates 3, 4 of the housing 2. The heel 17 has at its upper 21 and lower 22 ends a stud 23, 24 engaging in holes 25 , 26 made in the operating rod 6, which ensures the connection between the operating rod 6 and the heel 17. The latter has a toothing 27 cooperating with a device 28 for automatic return to the locking position of the rod 6.

Ce dispositif 28 comporte un flasque 29 dont le chant 30 est pourvu d'une denture 31 coopérant avec la denture 27 du talon 17. Ce flasque 29 pivote autour d'un axe fixe 32 traversé transversalement par l'une des extrémités 33 d'un ressort en spirale 34 dont l'autre extrémité 35 vient s'accrocher à une butée 36 solidaire du flasque 29. Lors de l'action sur le fouillot 7, la tringle de manoeuvre 6, coulissant derrière une têtière de recouvrement et de guidage 37, provoque, par la coopération des dentures 27 et 31, la rotation du flasque 29 et, de ce fait, la compression du ressort en spirale 34.This device 28 comprises a flange 29 whose edge 30 is provided with a toothing 31 cooperating with the toothing 27 of the heel 17. This flange 29 pivots about a fixed axis 32 traversed transversely by one of the ends 33 of a spiral spring 34, the other end 35 of which hangs on a bu tee 36 integral with the flange 29. During the action on the follower 7, the operating rod 6, sliding behind a cover and guide faceplate 37, causes, by the cooperation of the teeth 27 and 31, the rotation of the flange 29 and, therefore, the compression of the spiral spring 34.

Pendant l'ouverture de l'ouvrant, la tringle de manoeuvre 6 doit être maintenue en position de déverrouillage. Un tel dispositif de maintien en position déverrouillée fait l'objet de la demande divisionnaire européenne 82 108 310.2 déposée le 9 septembre 1982. Il a été désigné par 38 dans son ensemble. Il comporte deux branches perpendiculaires 40, 41 présentant une section d'une croix. Une des branches 40 est parallèle à la face avant 42 de la têtière 37. L'extrémité arrière 43 de l'autre branche 41 vient se loger dans une lumière 44 pratiquée dans le talon 17 et elle est maintenue dans cette lumière 44 par l'extrémité 45, 46 de deux éléments élastiques 47, 48 dont l'autre extrémité 49, 50 est fixée par des éléments de fixation 51, 52 sur les faces internes 53, 54 des plaques parallèles 3 et 4 (voir figure 4). La branche 40 se déplace transversalement par rapport à la face avant 42 de la têtière 37 dans une coulisse 55 et elle est maintenue par deux griffes 56, 57 coiffant les extrémités supérieure 58 et inférieure 59 de la branche 40. L'extrémité avant 60 de la branche 41, faisantsaillie par rapport à la face avant 42 de latêtiè- re 37, se déplace latéralement entre le chant inférieur 61 de la griffe supérieure 56 et le chant supérieur 62 de la griffe inférieure 57 (voir figure 3). Pour assurer le verrouillage automatique de la crémone-serrure et, par voie de conséquence, de la porte ou porte-fenêtre lors de la fermeture de l'ouvrant, il est nécessaire de dégager l'extrémité arrière 43 de la branche 41 de l'élément de blocage 39 de la lumière 44 du talon 17. On l'obtient en poussant latéralement sur l'extrémité avant 60 de cette même branche 41. Il en résulte un déplacement de l'extrémité 45, 46 du ressort 47, 48 qui traverse une lumière 63, 64 réalisée dans les plaques parallèles 3, 4 (voir figures 4 et 6).During the opening of the opening, the operating rod 6 must be kept in the unlocked position. Such a device for holding in the unlocked position is the subject of European divisional application 82 108 310.2 filed on September 9, 1982. It has been designated by 38 as a whole. It has two perpendicular branches 40, 41 having a cross section. One of the arms 40 is parallel to the front face 42 of the headrest 37. The rear end 43 of the other arm 41 is housed in a hole 44 made in the heel 17 and it is held in this hole 44 by the end 45, 46 of two elastic elements 47, 48, the other end 49, 50 of which is fixed by fastening elements 51, 52 on the internal faces 53, 54 of the parallel plates 3 and 4 (see FIG. 4). The branch 40 moves transversely relative to the front face 42 of the headrest 37 in a slide 55 and it is held by two claws 56, 57 covering the upper 58 and lower 59 ends of the branch 40. The front end 60 of the branch 41, projecting with respect to the front face 42 of the headrest 37, moves laterally between the lower edge 61 of the upper claw 56 and the upper edge 62 of the lower claw 57 (see FIG. 3). To ensure automatic locking of the bolt lock and, consequently, of the door or French window when the opening is closed, it is necessary to release the rear end 43 of the branch 41 of the blocking element 39 of the light 44 of the heel 17. It is obtained by pushing laterally on the front end 60 of this same branch 41. This results in a displacement of the end 45, 46 of the spring 47, 48 which passes through a light 63, 64 produced in the parallel plates 3, 4 (see FIGS. 4 and 6).

.Pour provoquer ce déplacement latéral, on prévoit des moyens de déblocage 65 solidaires du chant du dormant. ces moyens de déblocage 65 comportent une butée 66 dont la face 67 coopère avec la face latérale 68 de l'extrémité avant 60 de la branche 41 de l'élément de blocage 39. Cette butée 66 est disposée entre deux évidements 69, 70 dans lesquels vien- nentse loger les griffes 56, 57. La pénétration de ces griffes 56, 57 est limitée par les fonds 71, 72 de ces évidements 69, 70..To cause this lateral movement, release means 65 are provided which are integral with the edge of the frame. these unlocking means 65 comprise a stop 66 whose face 67 cooperates with the lateral face 68 of the front end 60 of the branch 41 of the locking element 39. This stop 66 is disposed between two recesses 69, 70 in which comes to house the claws 56, 57. The penetration of these claws 56, 57 is limited by the bottoms 71, 72 of these recesses 69, 70.

Lors de la fermeture de l'ouvrant, le fonctionnement de la crémone-serrure, conforme à l'invention. est le suivant:When the opening is closed, the operation of the locking lever, in accordance with the invention. is the next:

La face 67 de la butée 66 des moyens de déblocage 65 repousse latéralement l'extrémité avant 60 de la branche 41 et, par voie de conséquence, l'élément de blocage 39 coulisse dans la coulisse 55 sollicitant le ressort 48. De ce fait, on dégage l'extrémité arrière 43 de la branche 41 de l'élément de blocage 39 de la lumière 44 du talon 17. Le ressort en spirale 34 se détend, et fait pivoter le flasque 29. La denture 31 du flasque 29 entraîne la denture 27 du talon 17 et il y a déplacement automatique de la tringle 6 depuis sa position de déverrouillage à sa position de verrouillage (voir figures 5 à 7).The face 67 of the stop 66 of the release means 65 laterally pushes the front end 60 of the branch 41 and, consequently, the locking element 39 slides in the slide 55 biasing the spring 48. As a result, the rear end 43 of the branch 41 of the blocking element 39 of the light 44 of the heel 17 is released. The spiral spring 34 relaxes, and causes the flange 29 to pivot. The toothing 31 of the flange 29 drives the toothing 27 of the heel 17 and there is automatic displacement of the rod 6 from its unlocking position to its locking position (see FIGS. 5 to 7).

Pour condamner l'ouverture de la porte ou porte-fenêtre, on prévoit un second ensemble amenant et maintenant en position de verrouillage la tringle de manoeuvre 6 et assurant, par voie de conséquence, la condamnation de la crémone-serrure 1. Ce second ensemble est essentiellement constitué d'un pêne horizontal 73 guidé horizontalement par deux axes 74, 75 coulissant dans des lumières horizontales 76, 77 pratiquées dans les plaques parallèles 3, 4 du boîtier 2. Ce pêne transversal 73 comporte un plan incliné 78 coopérant avec un axe 79 solidaire du talon 17 de la tringle de manoeuvre 6. Le plan incliné 78 s'étend depuis l'extrémité supérieure 80 d'un doigt 81 jusqu'au chant supérieur 82 du corps 83 dudit pêne horizontal 73. Ce chant supérieur 82 comporte des évidements 84, 85, 86 dans lesquels vient se loger un téton 87 solidaire d'un pêne vertical 88. Ce pêne vertical 88 est maintenu en place par un élément élastique 89 partiellement enroulé autour d'un axe 90. L'une des branches 91 de cet élément élastique 89 prend appui contre le chant supérieur 92 du pêne vertical 88 et l'autre branche 93 prend appuis contre le pourtour 94 du fouillot 7. Le pêne vertical 88 est guidé, d'une part, par le téton 87 et, d'autre part, par un téton 95 coulissant dans des lumières verticales 96, 97 réalisées dans les plaques parallèles 3, 4 du boîtier 2. Par ailleurs, le chant inférieur 98 du pêne vertical 88 et le chant inférieur 99 du pêne horizontal 73 pourvu d'une denture 100 coopèrent avec un panneton ou un doigt de commande 101 d'une clé ou d'un barillet 102.To block the opening of the door or French window, a second assembly is provided bringing and now in the locking position the operating rod 6 and ensuring, consequently, the locking of the bolt-lock 1. This second assembly essentially consists of a horizontal bolt 73 guided horizontally by two axes 74, 75 sliding in horizontal slots 76, 77 formed in the parallel plates 3, 4 of the housing 2. This transverse bolt 73 has an inclined plane 78 cooperating with an axis 79 integral with the heel 17 of the operating rod 6. The inclined plane 78 extends from the upper end 80 of a finger 81 to the upper edge 82 of the body 83 of said horizontal bolt 73. This upper edge 82 includes recesses 84, 85, 86 in which is housed a stud 87 secured to a vertical bolt 88. This vertical bolt 88 is held in place by an elastic element 89 partially wound around an axis 90. One of the branches 91 of this elastic element 89 bears against the upper edge 92 of the vertical bolt 88 and the other branch 93 bears against the periphery 94 of the follower 7. The vertical bolt 88 is guided, on the one hand, by the stud 87 and, d on the other hand, by a stud 95 sliding in vertical slots 96, 97 produced in the parallel plates 3, 4 of the housing 2. Furthermore, the lower edge 98 of the vertical bolt 88 and the lower edge 99 of the horizontal bolt 73 provided with 'A toothing 100 cooperates with a bit or a control finger 101 of a key or a barrel 102.

Le fonctionnement de ce second ensemble amenant et maintenant en position de verrouillage la tringle de manoeuvre 6 de la crémone-serrure 1 pourvue d'une poignée est le suivant:The operation of this second assembly bringing and now in the locking position the operating rod 6 of the bolt lock 1 provided with a handle is as follows:

On considère que la crémone-serrure 1 est en position de décondamnation comme représentée dans la figure 1 et qu'elle doit être condamnée en position de verrouillage comme représentée dans la figure 5. On considère également que le ressort en spirale 34 n'a pas pu effectuer correctement le rappel automatique de la tringle de manoeuvre 6 malgré le déblocage de l'ensemble 38 de maintien en position de déverrouillage. De ce fait, la tringle de manoeuvre 6 et, en conséquence, la crémone-serrure 1 ne se trouvant plus en position de déverrouillage et pas encore en position de verrouillage, se trouvent dans une position intermédiaire. En actionnant le barillet 102, le doigt 101 repousse vers le haut le pêne vertical 88, ce qui permet de dégager le téton 87 de l'évidement 84 du pêne horizontal 73. Puis, le doigt 101 coopère avec la denture 100 du pêne horizontal 73 en lui impliquant une avance dirigée vers la têtière 37. L'extrémité supérieure 80 du doigt 81 prend contact avec l'axe 79 du talon 17 de la tringle de manoeuvre 6. Au cours de l'avance du pêne horizontal 73, ce doigt 81 oblige l'axe 79 de glisser le long du plan incliné 78 de ce doigt 81 et l'axe 79 descend au-fur-et-à-mesure de l'avance dudit pêne horizontal 73 en exerçant une traction sur la tringle de manoeuvre 6. Finalement, l'axe 79 et la tringle de manoeuvre 6 occupent la position de verrouillage. Ainsi, en actionnant le barillet, on est certain que la crémone-serrure est amenée en position de verrouillage et l'ouverture de la porte ou porte-fenêtre est condamnée, malgré une fatigue éventuelle du ressort en spirale 34.It is considered that the bolt lock 1 is in the unlocked position as shown in Figure 1 and that it must be locked in the locked position as shown in Figure 5. It is also considered that the spiral spring 34 has not could correctly perform the automatic return of the operating rod 6 despite the unlocking of the assembly 38 for holding in the unlocked position. Therefore, the operating rod 6 and, consequently, the lock-bolt 1 no longer being in the unlocked position and not yet in the locked position, are in an intermediate position. By actuating the barrel 102, the finger 101 pushes up the vertical bolt 88, which makes it possible to disengage the stud 87 from the recess 84 of the horizontal bolt 73. Then, the finger 101 cooperates with the teeth 100 of the horizontal bolt 73 by involving an advance directed towards the headrest 37. The upper end 80 of the finger 81 makes contact with the axis 79 of the heel 17 of the operating rod 6. During the advance of the horizontal bolt 73, this finger 81 forces the axis 79 to slide along the inclined plane 78 of this finger 81 and the axis 79 descends as the horizontal bolt 73 advances by exerting traction on the operating rod 6 Finally, the axis 79 and the operating rod 6 occupy the locking position. Thus, by actuating the barrel, it is certain that the locking lever is brought in locked position and the opening of the door or French window is condemned, despite possible fatigue of the spiral spring 34.
