Description

L'invention concerne une crémone à larder à double action comprenant un boîtier solidaire d'une têtière et renfermant un mécanisme de crémone composé d'un fouillot denté engrènant directement dans des dentures réalisées dans l'extrémité, disposées de part et d'autre du fouillot denté, de deux tringles de manoeuvre agissant en direction opposée et actionnant un pêne battant par l'intermédiaire d'un doigt solidaire du fouillot denté et engagé entre deux butées espacées solidaires du pêne battant.The invention relates to a double action latching bolt comprising a housing integral with a headrest and containing a lever mechanism composed of a toothed nut engaging directly in the teeth produced in the end, arranged on either side of the toothed nut, two operating rods acting in the opposite direction and actuating a beating bolt by means of a finger secured to the toothed nut and engaged between two spaced stops secured to the beating bolt.

On connaît, par le brevet FR-A-1 345 596, une crémone à larder à double action comprenant un boîtier solidaire d'une têtière et renfermant un mécanisme de crémone composé d'un fouillot denté engrènant directement dans des dentures réalisées dans l'extrémité disposée de part et d'autre du fouillot denté de deux tringles de manoeuvre agissant en direction opposée. Cette conception est avantageuse du fait de la disposition de deux tringles disposées de part et d'autre du fouillot et de la coopération directe de ces tringles avec ledit fouillot. En effet, cette conception permet de faire agir les tringles en sens opposé avec une course identique, contrairement aux conceptions antérieures des crémones à larder selon lesquelles le fouillot ne commande qu'une seule tringle, la commande de l'autre tringle étant obtenue par un engrenage inverseur. Cependant, cet engrenage inverseur implique une perte de course pour l'autre tringle que supprime la crémone à larder connue par ce brevet.We know, from patent FR-A-1 345 596, a double-action larding cremone bolt comprising a housing secured to a headrest and enclosing a cremone mechanism composed of a toothed nut engaging directly in the teeth produced in the end disposed on either side of the toothed follower of two operating rods acting in opposite directions. This design is advantageous due to the arrangement of two rods arranged on either side of the follower and the direct cooperation of these rods with said follower. Indeed, this design makes it possible to act on the rods in the opposite direction with an identical stroke, unlike previous designs of rods for larding according to which the follower controls only one rod, the control of the other rod being obtained by a reverse gear. However, this reversing gear implies a loss of travel for the other rod which eliminates the bolt lock known by this patent.

Toutefois, la crémone à larder connue par ledit brevet ne permet qu'un verrouillage aux extrémités de la crémone et non pas un verrouillage intermédiaire par pêne battant tel que prévu dans les conceptions antérieures de crémones à larder et connues par le brevet FR-A-1 013 125.However, the latch bolt known by said patent only allows locking at the ends of the latch and not an intermediate locking by beating bolt as provided in previous designs of latch bolts and known by the patent FR-A- 1,013,125.

Par ailleurs, on connaît, par le document FR-A-391 768, une crémone à larder à double action cor- recpondant au préambule de la revendication 1 et comprenant un boîtier solidaire d'une têtière et renfermant un mécanisme de crémone composé d'un fouillot denté engrènant directement dans des dentures réalisées dans l'extrémité disposée de part et d'autre du fouillot denté, de deux tringles de manoeuvre agissant en direction opposée et actionnant un pêne battant par l'intermédiaire d'un doigt solidaire du fouillot denté et engagé entre les deux butées espacées solidaires du pêne battant. Toutefois, toute rotation du fouillot denté agit simultanément sur les deux tringles de manoeuvre et sur le pêne battant tant dans la phase de verrouillage que dans la phase de déverrouillage.Furthermore, document FR-A-391 768 discloses a double action latch bolt corresponding to the preamble of claim 1 and comprising a housing secured to a headrest and containing a cremone mechanism composed of a toothed follower meshing directly into the teeth produced in the end arranged on either side of the toothed follower, of two operating rods acting in opposite direction and actuating a beating bolt by means of a finger secured to the toothed follower and engaged between the two spaced stops integral with the beating bolt. However, any rotation of the toothed nut acts simultaneously on the two operating rods and on the beating bolt both in the locking phase and in the unlocking phase.

Le but de la présente invention consiste à créer une crémone à larder à double action comportant simultanément les avantages d'un engrenage direct du fouillot sur les deux tringles ainsi que ceux d'un verrouillage intermédiaire par pêne battant et permettant, d'une part, l'entrée en action du verrouillage intermédiaire par le pêne battant avec un certain retard par rapport à l'entrée en action du verrouillage des extrémités de la crémone et, d'autre part, le déverrouillage simultané du verrouillage intermédiaire par le pêne battant et du verrouillage des extrémités de la crémone.The aim of the present invention is to create a double action latching rod which simultaneously has the advantages of a direct gear of the follower on the two rods as well as those of an intermediate locking by beating bolt and allowing, on the one hand, the entry into action of the intermediate locking by the latch bolt with a certain delay compared to the entry into action of the locking of the ends of the cremone bolt and, on the other hand, the simultaneous unlocking of the intermediate locking by the beating latch and of the locking the ends of the lever.

Cet objectif est atteint en prévoyant une crémone à larder à double action comprenant un boîtier solidaire d'une têtière et renfermant un mécanisme de crémone composé d'un fouillot denté engrènant directement dans des dentures réalisées dans l'extrémité disposée de part et d'autre du fouillot denté, deux tringles de manoeuvre agissant en direction opposée et actionnant un pêne battant par l'intermédiaire d'un doigt solidaire du fouillot denté et engagé entre deux butées espacées solidaires du pêne battant, caractérisée en ce que le doigt, solidaire en rotation du fouillot denté, comporte, en phase de verrouillage, une course à vide avant d'agir, par l'intermédiaire d'une des butées, sur le pêne battant et qu'au moins une des tringles comporte une surface d'attaque disposée, dans la position verrouillée de la crémone, en face d'une rampe solidaire du pêne battant et agissant sur le pêne battant par l'intermédiaire de la rampe dès la rotation du fouillot denté vers sa position correspondant à la position d'ouverture de la crémone.This objective is achieved by providing a double action latching bolt comprising a housing secured to a headrest and enclosing a lever mechanism composed of a toothed nut engaging directly in the teeth produced in the end arranged on either side. of the toothed nut, two operating rods acting in the opposite direction and actuating a latch bolt by means of a finger secured to the toothed follower and engaged between two spaced stops secured to the latch bolt, characterized in that the finger, integral in rotation of the toothed nut, comprises, in the locking phase, an idle stroke before acting, by means of one of the stops, on the beating bolt and that at least one of the rods has an attack surface arranged, in the locked position of the cremone bolt, in front of a ramp secured to the beating bolt and acting on the beating bolt via the ramp as soon as the toothed nut rotates towards its corresponding position ant to the open position of the lever.

Les avantages obtenus grâce à cette invention consistent essentiellement en ce qu'on réalise, en phase de verrouillage, sur le pêne battant une action retardée par rapport aux deux tringles de manoeuvre alors qu'en phase de déverrouillage, on agit immédiatement sur le pêne battant par l'intermédiaire d'une des tringles de manoeuvre, le pêne battant pouvant pivoter par rapport au fouillot denté.The advantages obtained thanks to this invention consist essentially in that, in the locking phase, a delayed action is carried out on the beating bolt with respect to the two operating rods, whereas in the unlocking phase, one acts immediately on the beating bolt via one of the operating rods, the beating bolt being able to pivot relative to the toothed nut.

Ainsi, la crémone à larder à double action conçue selon les caractéristiques précipées permet de réaliser le but que l'invention s'est fixée et d'obtenir également des avantages importants pour la réalisation de fenêtres ou porte-fenêtres modernes.Thus, the double action latching rod designed according to the precipitated characteristics makes it possible to achieve the aim which the invention has set for itself and also to obtain significant advantages for the production of modern windows or French windows.

Celles-ci sont équipées de joints d'étanchéité et la présence de ces derniers entraîne une dureté de manoeuvre de la crémone. L'invention, permettant la succession de l'entrée en action des verrouillages d'extrémité et du verrouillage intermédiaire, réduit l'effort à fournir lors du verrouillage des fenêtres ou porte-fenêtres.These are fitted with seals and the presence of these results in a hardness in operating the cremone bolt. The invention, allowing the succession of the entry into action of the end locks and of the intermediate lock, reduces the effort to be provided when locking windows or French windows.

Si, en plus, avec le temps, le ou les ouvrants de ces fenêtres ou porte-fenêtres ont légèrement gauchis ou se sont bombés, l'entrée en action du verrouillage intermédiaire, après un premier rapprochement de l'ouvrant contre le dormant par les verrouillages d'extrémité, évite un décalage total du pêne battant par rapport à sa gâche et annihile, de ce fait, l'impossibilité de fermer la fenêtre ou porte-fenêtre.If, in addition, over time, the opening (s) of these windows or French windows have slightly warped or bulged, the entry into action of the intermediate locking, after a first approach of the opening against the frame by the end locks, avoids a total offset of the beating bolt relative to its strike and annihilates, therefore, the inability to close the window or French window.

De même, la réalisation des crémones à larder et avantagée par l'invention. L'entrée en action du verrouillage intermédiaire après l'entrée en action des verrouillages d'extrémité permet de réduire sur le pêne battant et dans l'entrée de la gâche les conicités nécessaires pour faciliter l'engagement du pêne battant dans la gâche. La réduction de ces conicités permet une réduction de l'épaisseur de la crémone. Cette réduction de l'épaisseur de la crémone ne constitue pas seulement un avantage de la crémone mais également un avantage pour la réalisation des fenêtres ou porte-fenêtres, étant donné qu'un boîtier de crémone de faible épaisseur nécessite une entaille moins large et, de ce fait, le montant de l'ouvrant de la fenêtre ou porte-fenêtre est moins affaibli.Likewise, the production of cremones to be larded and advantageous by the invention. The entry into action of the intermediate lock after the entry into action of the end locks makes it possible to reduce on the swing bolt and in the entry of the strike the conicities necessary to facilitate the engagement of the swing bolt in the strike. The reduction of these tapers allows a reduction in the thickness of the cremone bolt. This reduction in the thickness of the cremone bolt is not only an advantage of the cremone bolt but also an advantage for the production of windows or French windows, since a cremone bolt case of thin thickness requires a notch narrower and, as a result, the amount of the window sash or French window is less weakened.

Une application avantageuse de l'invention s'obtient lorsque le pêne battant est articulé sur un arbre concentrique au fouillot. Cette dernière caractéristique permet, en effet, de diminuer la longueur du boîtier pour conférer à ce dernier une faible dimension.An advantageous application of the invention is obtained when the beating bolt is articulated on a shaft concentric with the follower. This last characteristic makes it possible, in fact, to reduce the length of the housing to give the latter a small dimension.

Une autre application avantageuse de l'invention se caractérise en ce que la pêne battant comporte la rampe sur l'un de ses chants.Another advantageous application of the invention is characterized in that the beating bolt comprises the ramp on one of its edges.

D'autres applications avantageuses ressortent de la description ci-après.Other advantageous applications will emerge from the description below.

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 embodiment.

La figure 1 représente, en vue en élévation, une crémone à larder à double action avec pêne battant, conforme à l'invention, la crémone étant en position déverrouillée et le couvercle du boîtier étant enlevé.Figure 1 shows, in elevational view, a double action latching bolt with beating bolt, according to the invention, the cremone bolt being in the unlocked position and the housing cover being removed.

La figure 2 représente, en vue en élévation, la même crémone mais en position de verrouillage.Figure 2 shows, in elevation view, the same cremone bolt but in the locked position.

On se réfère aux deux figures.We refer to the two figures.

La crémone à larder à double action 1 comporte un boîtier 2 présentant sur sa face avant 3 une têtière 4. Le long de la face arrière 5 de la têtière 4 coulissent en direction opposée deux tringles de manoeuvre 6, 7. Ces tringles de manoeuvre 6, 7 comportent des éléments de verrouillage (non représentés) coopérant avec des gâches (non représentées) solidaires du dormant de la fenêtre, porte, porte-fenêtre ou analogues. Ces tringles de manoeuvre 6, 7 assurent un verrouillage des extrémités de la crémone à larder 1.The double action latch bolt 1 comprises a housing 2 having on its front face 3 a headrest 4. Along the rear face 5 of the headrest 4 slide in the opposite direction two operating rods 6, 7. These operating rods 6 , 7 comprise locking elements (not shown) cooperating with strikes (not shown) integral with the window frame, door, French window or the like. These operating rods 6, 7 ensure locking of the ends of the latch bolt 1.

Le boîtier 2 renferme un mécanisme de crémone 8. Ce dernier est composé essentiellement d'un fouillot 9 actionné par le carré de manoeuvre 10 d'une poignée (non représentée). Le fouillot 9 comporte une couronne dentée 11 dont les dents 12, 13... engrènent directement dans des dentures 14, 15 réalisées dans les extrémités 16, 17 des tringles de manoeuvre 6, 7, ces extrémités 16, 17 étant disposées de part et d'autre du fouillot 9.The housing 2 contains a lever mechanism 8. The latter is essentially composed of a nut 9 actuated by the operating square 10 of a handle (not shown). The follower 9 comprises a toothed ring 11 whose teeth 12, 13 ... mesh directly with teeth 14, 15 produced in the ends 16, 17 of the operating rods 6, 7, these ends 16, 17 being arranged on one side and on the other side of the follower 9.

Ce dernier coopère par l'intermédiaire d'un doigt 18 avec un pêne battant 19 articulé sur un arbre 20 logé dans le boîtier 2. La tête 21 de ce pêne battant 19 traverse une lumière 22 réalisée dans la têtière 4 et, en position de verrouillage, s'engage dans une gâche (non représentée) solidaire du dormant de la fenêtre, porte, porte-fenêtre ou analogue, alors qu'en position de déverrouillage, ladite tête 21 est escamotée dans le boîtier 2.The latter cooperates by means of a finger 18 with a beating bolt 19 articulated on a shaft 20 housed in the housing 2. The head 21 of this beating bolt 19 passes through a light 22 made in the headrest 4 and, in the position of locking, engages in a keeper (not shown) integral with the window frame, door, French window or the like, while in the unlocking position, said head 21 is retracted into the housing 2.

Selon un autre mode de réalisation, le pêne battant 19 est articulé sur un arbre concentrique au fouillot 9, ce qui permet de réduire la longueur 23 du boîtier 2.According to another embodiment, the beating bolt 19 is articulated on a shaft concentric with the nut 9, which makes it possible to reduce the length 23 of the housing 2.

Selon un autre mode de réalisation, le fouillot 9 comporte une portée sur laquelle peut pivoter le pêne battant 19.According to another embodiment, the nut 9 has a bearing on which the swing bolt 19 can pivot.

Celui-ci sert d'élément de verrouillage intermédiaire. Cependant, il est souhaitable que l'entrée en action du verrouillage intermédiaire réalisé par le pêne battant 19 s'effectue postérieurement à l'entrée en action du verrouillage des extrémités de la crémone réalisé par les tringles de manoeuvre 6, 7 alors qu'inversement le déverrouillage du verrouillage intermédiaire et de déverrouillage du verrouillage d'extrémités doivent s'effectuer simultanément.This serves as an intermediate locking element. However, it is desirable that the entry into action of the intermediate locking effected by the beating bolt 19 takes place after the entry into action of the locking of the ends of the cremone rod effected by the operating rods 6, 7 while conversely the unlocking of the intermediate locking and the unlocking of the end locking must be carried out simultaneously.

A cet effet, l'invention prévoit différents moyens. Le pêne battant 19 comporte deux butées espacées 24, 25 entre lesquelles se déplace à vide le doigt 18 du fouillot 9, c'est-à-dire que le fouillot 9 n'agit pas sur le pêne battant 19, pendant une partie de sa rotation.To this end, the invention provides various means. The latch bolt 19 has two spaced stops 24, 25 between which the finger 18 of the follower 9 moves empty, that is to say that the follower 9 does not act on the latch bolt 19, during part of its rotation.

Selon un autre mode de réalisation, ces deux butées espacées 24, 25 sont les chants d'extrémités d'une lumière 26 réalisée dans le corps 27 du pêne battant 19. Avantageusement, cette lumière 26 est une lumière curviligne dont le centre de cintrage est le centre de rotation du fouillot 9.According to another embodiment, these two spaced stops 24, 25 are the edges of the ends of a light 26 produced in the body 27 of the beating bolt 19. Advantageously, this light 26 is a curvilinear light whose bending center is the center of rotation of the follower 9.

Selon un autre mode de réalisation, ces deux butées espacées 24, 25 sont des tétons faisant saillie par rapport à l'une des faces du corps 27 du pêne battant 19 entre lesquels se déplace le doigt 18 du pêne battant 19.According to another embodiment, these two spaced stops 24, 25 are studs projecting with respect to one of the faces of the body 27 of the latch bolt 19 between which the finger 18 of the latch bolt 19 moves.

Pour le déverrouillage simultané, au moins une des tringles de manoeuvre 6, 7 comporte une surface d'attaque 28 agissant sur le pêne battant 19. Ce dernier comporte au moins une rampe 29 faisant face à la surface d'attaque 28 lorsque la crémone à larder 1 est en position verrouillée.For the simultaneous unlocking, at least one of the operating rods 6, 7 comprises an attack surface 28 acting on the latch bolt 19. The latter comprises at least one ramp 29 facing the attack surface 28 when the cremone bolt larder 1 is in the locked position.

Selon un mode d'exécution, la surface d'attaque 28 est située soit sur l'un ou l'autre chant longitudinal de la tringle de manoeuvre 6.According to one embodiment, the attack surface 28 is located either on one or the other longitudinal edge of the operating rod 6.

Selon un autre mode d'exécution, la surface d'attaque 28 est située sur le chant d'extrémité 30 de la tringle de manoeuvre 6.According to another embodiment, the attack surface 28 is located on the end edge 30 of the operating rod 6.

Lorsque la surface d'attaque 28 est située sur l'un ou l'autre chant longitudinal de la tringle de manoeuvre 6, il est souhaitable que la rampe 29 fasse saillie par rapport à l'une ou l'autre face du pêne battant 19.When the attack surface 28 is located on one or the other longitudinal edge of the operating rod 6, it is desirable for the ramp 29 to project relative to one or the other face of the beating bolt 19 .

Si la surface d'attaque 28 est située sur le chant d'extrémité 30 de la tringle de manoeuvre 6, il est avantageux que le pêne battant 19 comporte la rampe 29 sur son chant 31.If the attack surface 28 is located on the end edge 30 of the operating rod 6, it is advantageous for the beating bolt 19 to have the ramp 29 on its edge 31.

Le fonctionnement de la crémone à larder conforme à l'invention est le suivant:The operation of the cremone bolt in accordance with the invention is as follows:

La crémone à larder est en position d'ouverture telle que représentée dans la figure 1. En actionnant la poignée, on implique au fouillot 9 une rotation dans le sens de déplacement des aiguilles d'une montre. Les dents du fouillot 9 engrènent dans les dentures 14, 15 des tringles de manoeuvre 6, 7 de sorte que ces dernières se déplacent en direction opposée l'une par rapport à l'autre et on obtient l'entrée en action du verrouillage des extrémités. Parallèlement, le doigt 18 du fouillot 9 parcourt l'espace entre les deux butées 25, 24 sans agir sur le pêne battant 19. Lorsque le doigt 18. entre en contact avec la butée 24, la rotation du fouillot 9 est transmise au pêne battant 19. Ainsi, l'entrée en action du verrouillage intermédiaire est postérieure à celle de l'action du verrouillage des extrémités.The cremone bolt is in the open position as shown in Figure 1. By actuating the handle, it involves the follower 9 a rotation in the direction of movement of the needles of a watch. The teeth of the follower 9 mesh in the teeth 14, 15 of the operating rods 6, 7 so that the latter move in opposite directions relative to each other and the entry into action of the locking of the ends is obtained. . In parallel, the finger 18 of the follower 9 traverses the space between the two stops 25, 24 without acting on the latch bolt 19. When the finger 18. comes into contact with the stop 24, the rotation of the follower 9 is transmitted to the latch bolt 19. Thus, the entry into action of the intermediate locking is later than that of the action of locking the ends.

En phase de àéverrouillage, on actionne la poignée en sens contraire, ce qui provoque la rotation dans le sens contraire de déplacement des aiguilles d'une montre du fouillot 9. Les dents du fouillot 9 engrènent dans les dentures 14, 15 des tringles de manoeuvre 6, 7 et exercent, de ce fait, une traction sur ces dernières. La surface d'attaque 28 de la tringle de manoeuvre 6 glisse le long de la rampe 29 du pêne battant 19 en provoquant la rotation de ce dernier. Ainsi, en phase de déverrouillage, il y a action simultanée sur le verrouillage intermédiaire et sur le verrouillage des extrémités.In the unlocking phase, the handle is actuated in the opposite direction, which causes the rotation in the counterclockwise movement of the clockwise of the follower 9. The teeth of the follower 9 mesh in the teeth 14, 15 of the operating rods 6, 7 and therefore exert traction on the latter. The attack surface 28 of the rod maneuver 6 slides along the ramp 29 of the beating bolt 19 causing the rotation of the latter. Thus, in the unlocking phase, there is simultaneous action on the intermediate locking and on the locking of the ends.
