Description

La présente invention concerne le domaine des dispositifs de commande des systèmes de verrouillage/déverrouillage d'un ouvrant tel qu'un vantail de fenêtre ou de porte. Elle concerne en particulier les dispositifs qui peuvent être vendus séparément des ouvrants pour être installés sur site sur des ferrures de verrouillage/déverrouillage de type crémone. Plus particulièrement l'invention a trait aux dispositifs de commande qui se montent en applique sur un montant d'ouvrant, notamment pour les ouvrants coulissants de porte ou de fenêtre.The present invention relates to the field of control devices for locking/unlocking systems of an opening such as a window or door leaf. It concerns in particular devices which can be sold separately from the openings to be installed on site on cremone type locking/unlocking fittings. More particularly, the invention relates to control devices which are mounted on an opening post, in particular for sliding door or window openings.

Il est courant d'utiliser des dispositifs de verrouillage/déverrouillage à crémone avec béquilles pivotantes, dans le domaine des ouvrants, tels que des fenêtres ou portes, dont l'ouverture de l'ouvrant se fait en général par rotation autour d'un axe de pivotement, dits à frappe.It is common to use cremone locking/unlocking devices with pivoting levers, in the field of openings, such as windows or doors, where the opening of the opening is generally done by rotation around an axis pivoting, called striking.

En effet il est connu de façon classique dans le domaine des ouvrants à frappe, d'utiliser des dispositifs de commande permettant d'agir sur le verrouillage/déverrouillage de ferrures de verrouillage/déverrouillage de type crémone encastrées dans le montant d'un ouvrant, comprenant une poignée tournante. Cette poignée agit par l'intermédiaire d'un arbre d'actionnement , en général une tige à section carrée dite carré d'actionnement, venant s'insérer en prise dans un orifice traversant à section carrée, le fouillot de crémone, de manière à transformer le mouvement de rotation de la poignée en un mouvement de translation sur lui-même de l'organe de verrouillage/déverrouillage suivant un montant de l'ouvrant. Cet organe de verrouillage/déverrouillage se présente en général sous forme d'au moins une tringle, le plus souvent de deux tringles. La poignée de commande est en général montée en applique sur un montant d'ouvrant, pour que sa rotation s'effectue autour de l'arbre d'actionnement monté transversalement au plan de l'ouvrant.Indeed, it is conventionally known in the field of striking openings to use control devices making it possible to act on the locking/unlocking of cremone type locking/unlocking fittings embedded in the amount of an opening, including a rotating handle. This handle acts via an actuating shaft, generally a rod with a square section called an actuation square, which is inserted into a through hole with a square section, the cremone follower, so as to transform the rotational movement of the handle into a movement of translation on itself of the locking/unlocking member following an amount of the opening. This locking/unlocking member is generally in the form of at least one rod, most often two rods. The control handle is generally mounted on an opening post, so that its rotation takes place around the actuating shaft mounted transversely to the plane of the opening.

Classiquement, en position vantail ouvert, la béquille est à l'horizontale (à 90 degrés) par rapport au montant sur lequel est montée la poignée. Une manoeuvre d'une course angulaire de 90 degrés de la béquille permet ainsi d'actionner d'un quart de tour le fouillot de la crémone, pour déverrouiller le vantail de la fenêtre en tournant dans un sens et de le verrouiller en tournant la béquille dans le sens inverse.Conventionally, in the open leaf position, the handle is horizontal (at 90 degrees) to the upright on which the handle is mounted. A maneuver of an angular stroke of 90 degrees of the handle thus makes it possible to activate the bolt follower by a quarter turn, to unlock the window leaf by turning in one direction and to lock it by turning the handle In the opposite way.

Ces dispositifs présentent des coûts compétitifs directement liés à leur production en masse.These devices have competitive costs directly linked to their mass production.

Toutefois pour ces dispositifs à crémone, en position déverrouillée, la béquille qui est à 90 degrés par rapport au montant sur lequel elle est appliquée, peut gêner visuellement ou physiquement.However, for these cremone devices, in the unlocked position, the crutch which is at 90 degrees relative to the upright on which it is applied, can be visually or physically obstructive.

En outre, notamment dans le cas des ouvrants coulissants, il se pose un problème d'ergonomie d'usage de la poignée. En effet sur un ouvrant coulissant, l'utilisateur va ouvrir le vantail en le faisant translater. Il va donc devoir tirer la béquille non pas vers lui comme pour une fenêtre à frappe, mais dans le sens de translation du vantail. En position vantail ouvert, la béquille étant à l'horizontale (à 90 degrés) par rapport au montant sur lequel est montée la poignée, la prise de la béquille peut être glissante donc peu ergonomique.In addition, particularly in the case of sliding openings, there is a problem of ergonomics of use of the handle. In fact, on a sliding opening, the user will open the leaf by moving it. He will therefore have to pull the handle not towards him as for a window, but in the direction of translation of the leaf. In the open leaf position, the handle being horizontal (at 90 degrees) to the upright on which the handle is mounted, gripping the handle can be slippery and therefore not very ergonomic.

Un autre problème est le risque de dégradation de la béquille. En effet une béquille à l'horizontale pour manoeuvrer le vantail secondaire d'un coulissant dans un plan horizontal peut entraîner un risque de choc de l'extrémité de la béquille sur le montant chicane du vantail principal.Another problem is the risk of damage to the crutch. In fact, a horizontal handle for operating the secondary leaf of a sliding door in a horizontal plane can cause a risk of the end of the handle hitting the chicane upright of the main leaf.

Un autre inconvénient est que la béquille à l'horizontale limite l'ouverture du vantail d'un espace au moins égal à la longueur de la béquille.Another disadvantage is that the horizontal handle limits the opening of the leaf by a space at least equal to the length of the handle.

Il est ainsi déjà connu de trouver, sur des ouvrants coulissants, des poignées adaptées à ce type particulier de menuiseries, mais ces poignées sont en général installées verticalement, avec un organe de manoeuvre du carré d'actionnement soit avec un bras de levier très court, soit avec une béquille dont la course angulaire est inférieure à 90 degrés, en général ne dépassant pas les 20 degrés.It is thus already known to find, on sliding openings, handles adapted to this particular type of joinery, but these handles are generally installed vertically, with an operating member of the actuating square or with a very short lever arm , or with a crutch whose angular travel is less than 90 degrees, generally not exceeding 20 degrees.

Dans la demande de brevet FR2865493 , on a ainsi proposé un dispositif permettant d'entraîner la rotation d'un arbre d'actionnement d'une crémone ou analogue sur un angle de valeur donnée au moyen de la rotation d'une poignée ou analogue sur un angle de valeur bien inférieure à ladite valeur donnée. Ce dispositif trouve des applications notamment dans la commande des crémones de portes et/ou de fenêtres, notamment de type coulissant pour des bâtiments d'habitation ou analogue.In the patent application FR2865493 , we have thus proposed a device making it possible to cause the rotation of an actuating shaft of a cremone bolt or the like over an angle of a given value by means of the rotation of a handle or the like over an angle of much lower value to said given value. This device finds applications in particular in the control of door and/or window cremones, in particular of the sliding type for residential buildings or the like.

Ces poignées ont toutefois un coût qui demeure plus élevé qu'une simple poignée de frappe, du fait d'un mode de fonctionnement et donc d'une conception plus complexe.These handles, however, have a cost which remains higher than a simple striking handle, due to a mode of operation and therefore a more complex design.

La demande de brevet FR3004207 décrit un dispositif de commande de crémone apte à commander des systèmes de verrouillage combinés quart de tour et demi-tour. Le dispositif comprend un arbre d'entraîneur dont une extrémité s'insère dans un organe de manoeuvre et l'autre extrémité se couple à une extrémité de couplage d'un axe adaptateur. L'extrémité de couplage dudit arbre d'entraîneur comporte deux ergots de saillie orientée axialement et dont les surfaces latérales peuvent venir en appui sur des surfaces en saillie d'une cavité en extrémité de la partie de couplage de l'adaptateur de sorte que ledit arbre entraîne en rotation ledit axe adaptateur sur un premier secteur angulaire de débattement dudit arbre et que ledit arbre n'entraîne pas en rotation ledit axe adaptateur sur un deuxième secteur angulaire de débattement dudit arbre, différent dudit premier secteur angulaire.The patent application FR3004207 describes a cremone control device capable of controlling combined quarter-turn and half-turn locking systems. The device comprises a drive shaft, one end of which inserts into an operating member and the other end couples to a coupling end of an adapter shaft. The coupling end of said drive shaft comprises two axially oriented projecting lugs whose lateral surfaces can bear on protruding surfaces of a cavity at the end of the coupling part of the adapter so that said shaft rotates said adapter axis on a first angular sector of movement of said shaft and that said shaft does not rotate said adapter axis on a second angular sector of movement of said shaft, different from said first angular sector.

La demande de brevet FR2836505 décrit une serrure à plusieurs points de condamnation du type comportant un fouillot actionnable par une béquille. La serrure comporte un actionneur comportant un secteur denté et coaxial au fouillot, apte à être entraîné en rotation par le fouillot dans un sens de rotation et restant en position lors du rappel en position du fouillot par un moyen élastique, ledit organe d'actionnement faisant partie d'une chaîne cinématique d'actionnement de tringles de condamnation. A cet effet le fouillot peut comporter un ergot coopérant avec les bords d'une lumière de l'actionneur de sorte que lorsqu'on actionne la béquille vers le bas, le fouillot n'agit pas sur l'actionneur car l'ergot débat librement à l'intérieur de la lumière de l'actionneur sans agir sur celui-ci, alors que lorsqu'on actionne la béquille vers le haut, l'ergot du fouillot pousse l'actionneur dans le sens de rotation correspondant à l'actionnement de la béquille.The patent application FR2836505 describes a lock with several locking points of the type comprising a follower operable by a handle. The lock comprises an actuator comprising a toothed sector coaxial with the follower, capable of being rotated by the follower in a direction of rotation and remaining in position when the follower is returned to position by an elastic means, said actuating member making part of a kinematic chain for actuating locking rods. For this purpose the follower can include a lug cooperating with the edges of a slot in the actuator so that when the lever is pressed downwards, the follower does not act on the actuator because the lug debates freely inside the light of the actuator without acting on it, whereas when the lever is activated upwards, the pin of the follower pushes the actuator in the direction of rotation corresponding to the actuation of the crutch.

L'invention vise à résoudre au moins en partie les problèmes évoqués ci-dessus. Elle vise à proposer un dispositif de commande alternatif d'un système de verrouillage/déverrouillage d'un ouvrant utilisant une crémone, et plus particulièrement s'appliquant à un ouvrant coulissant.

Avantageusement ledit moyen de couplage est en acier, ce qui contribue à une bonne résistance au cisaillement du dispositif.Advantageously, said coupling means is made of steel, which contributes to good shear resistance of the device.

En particulier ledit conduit transverse est creusé dans la masse de ladite partie de l'arbre et la traverse entièrement dans sa largeur (direction radiale de l'arbre).In particular, said transverse conduit is hollowed out in the mass of said part of the shaft and crosses it entirely in its width (radial direction of the shaft).

En particulier ladite au moins une ouverture est traversante selon la direction radiale de ladite paroi cylindrique autour de la cavité.In particular, said at least one opening passes through in the radial direction of said cylindrical wall around the cavity.

De préférence selon l'invention, ledit dispositif comprend deux ouvertures aménagées dans ladite paroi cylindrique et débouchantes dans ladite cavité, chaque dite ouverture ayant une forme de fente en arc de cercle qui s'étend d'une même longueur délimitée, et ledit moyen de couplage comprend deux éléments en saillie, disposés de sorte que lesdits éléments en saillie soient reçus respectivement dans une dite fente. La résistance au cisaillement du dispositif est encore améliorée selon cette configuration.Preferably according to the invention, said device comprises two openings arranged in said cylindrical wall and opening into said cavity, each said opening having the shape of an arcuate slot which extends the same delimited length, and said means of coupling comprises two projecting elements, arranged so that said projecting elements are received respectively in said slot. The shear resistance of the device is further improved according to this configuration.

De préférence, le/ les éléments en saillie du moyen de couplage est/sont situé(s) sur la périphérie dudit arbre d'actionnement. Quand lesdits éléments en saillie sont au nombre de deux, ils sont disposés de sorte qu'ils soient en concordance avec lesdites ouvertures dans lesquelles ils sont respectivement insérés.Preferably, the projecting element(s) of the coupling means is/are located on the periphery of said actuating shaft. When said projecting elements are two in number, they are arranged so that they are in concordance with said openings in which they are respectively inserted.

En particulier lesdites deux ouvertures aménagées dans ladite paroi cylindrique et débouchantes dans ladite cavité sont disposées de manière diamétralement opposées. En particulier lesdits éléments en saillie sont au nombre de deux et disposés de manière diamétralement opposés sur la périphérie dudit arbre d'actionnement, de sorte qu'ils soient en concordance avec lesdites deux ouvertures dans lesquelles ils sont respectivement insérés.In particular, said two openings arranged in said cylindrical wall and opening into said cavity are arranged diametrically opposite each other. In particular, said projecting elements are two in number and arranged diametrically opposite on the periphery of said actuating shaft, so that they are in concordance with said two openings in which they are respectively inserted.

Avantageusement ledit moyen de couplage est en acier, ce qui contribue à une bonne résistance au cisaillement du dispositif.Advantageously, said coupling means is made of steel, which contributes to good shear resistance of the device.

En particulier, ladite course active et ladite course inactive angulaires font chacune 90 degrés.In particular, said active stroke and said inactive angular stroke are each 90 degrees.

Avantageusement, le dispositif de commande est configuré pour fonctionner avec une crémone usuelle, c'est-à-dire de type quart de tour, qui a un fouillot à section carrée. L'orifice de l'organe de manoeuvre est aussi à section carrée.Advantageously, the control device is configured to operate with a usual cremone bolt, that is to say of the quarter-turn type, which has a follower with a square section. The orifice of the operating member is also square in section.

Selon un mode préféré de l'invention, ledit arbre d'actionnement est divisée en deux parties d'arbre distinctes, formant d'une part une partie d'arbre entrante dont une de ses extrémités (axiales) est insérée dans l'orifice d'entrée que comporte la cavité dudit support, et son extrémité opposée est apte à être insérée dans l'orifice récepteur que comporte l'organe de manoeuvre, et d'autre part une partie d'arbre sortante dont une de ses extrémités (axiales) est insérée dans l'orifice de sortie que comporte la cavité dudit support, et son extrémité opposée est apte à être insérée dans l'orifice d'actionnement (le fouillot) que comporte la crémone, ladite partie d'arbre sortante étant munie dudit moyen de couplage. Ledit orifice d'entrée de ladite cavité se situe du côté de l'organe de manoeuvre, et ledit orifice de sortie de ladite cavité se situe du côté de la crémone, lorsque le dispositif est installé entre l'organe de manoeuvre et la crémone.According to a preferred embodiment of the invention, said actuating shaft is divided into two distinct shaft parts, forming on the one hand an incoming shaft part of which one of its (axial) ends is inserted into the orifice of the entrance that the cavity of said support has, and its opposite end is capable of being inserted into the receiving orifice that the operating member has, and on the other hand an outgoing shaft part of which one of its (axial) ends is inserted into the outlet orifice that the cavity of said support comprises, and its opposite end is capable of being inserted into the actuation orifice (the follower) that the cremone has, said outgoing shaft part being provided with said means coupling. Said inlet orifice of said cavity is located on the side of the operating member, and said outlet orifice of said cavity is located on the side of the cremone, when the device is installed between the operating member and the cremone.

Avantageusement, chacune desdites deux parties d'arbre distinctes est à section carrée.Advantageously, each of said two distinct shaft parts has a square section.

En particulier le montage est réalisé de sorte que la course angulaire inactive de l'organe de manoeuvre puisse avoir lieu avant la course angulaire active de l'arbre d'actionnement, c'est-à-dire avant que la rotation de l'arbre d'actionnement puisse actionner le déverrouillage ou le verrouillage du système de verrouillage/déverrouillage à crémone. En particulier le sens de rotation de l'organe de manoeuvre peut être adapté au sens d'ouverture ou de fermeture par coulissement d'un ouvrant (vers la gauche ou vers la droite).In particular, the assembly is carried out so that the inactive angular stroke of the operating member can take place before the active angular stroke of the actuating shaft, that is to say before the rotation of the shaft actuation can activate the unlocking or locking of the cremone locking/unlocking system. In particular, the direction of rotation of the operating member can be adapted to the direction of opening or closing by sliding an opening (towards the left or to the right).

Selon un mode de réalisation préféré, ledit au moins un moyen d'aide au montage dudit moyen de couplage coopère avec ladite au moins une ouverture en forme de fente pour relier le sens du parcours entre les deux extrémités respectives de ladite au moins une fente au sens de rotation de l'organe de manoeuvre.According to a preferred embodiment, said at least one means of aiding the mounting of said coupling means cooperates with said at least one slot-shaped opening to connect the direction of travel between the two respective ends of said at least one slot to the direction of rotation of the operating member.

Dans la suite de la description, il est fait référence au trièdre orthonormé L,T,V représenté sur les figures, qui définit respectivement l'axe longitudinal, l'axe transversal, et l'axe vertical du convertisseur angulaire et de l'arbre d'actionnement d'un dispositif de commande selon l'invention. En outre il est fait référence au trièdre orthonormé X,Y,Z représenté sur les figures, qui définit respectivement la direction longitudinale, la direction transversale et la direction verticale pour un ouvrant coulissant qui s'installe usuellement dans un plan vertical.In the remainder of the description, reference is made to the orthonormal trihedron L, T, V represented in the figures, which respectively defines the longitudinal axis, the transverse axis, and the vertical axis of the angular converter and of the shaft actuation of a control device according to the invention. In addition, reference is made to the orthonormal trihedron X,Y,Z represented in the figures, which respectively defines the longitudinal direction, the transverse direction and the vertical direction for a sliding opening which is usually installed in a vertical plane.

Selon l'exemple, l'axe transversal T correspond à la direction de coulissement de l'ouvrant suivant son propre plan dans le dormant, soit la direction X, l'axe vertical V correspond à la direction du montant de fermeture, soit la direction Z, et l'axe longitudinal L correspond à la direction transversale de l'ouvrant, soit la direction Y.According to the example, the transverse axis T corresponds to the direction of sliding of the opening according to its own plane in the frame, i.e. the direction Z, and the longitudinal axis L corresponds to the transverse direction of the opening, i.e. the Y direction.

On comprendra que, sans sortir du contexte de l'invention, qu'on peut orienter différemment l'ouvrant par rapport au dormant, par exemple de manière à ce que l'ouvrant coulisse selon une direction verticale et que la tringle coulisse alors le long du montant de fermeture dans la direction longitudinale.It will be understood that, without departing from the context of the invention, that the opening can be oriented differently in relation to the frame, for example so that the opening slides in a vertical direction and the rod then slides along of the closure amount in the longitudinal direction.

Ledit moyen de couplage est constitué selon l'exemple d'une tige ronde de faible diamètre, telle qu'une goupille, dont les extrémités forment lesdits éléments en saillie. Ladite tige de couplage 13 est en acier.Said converter also comprises a coupling means 13 between said support 10 and said actuation shaft, and more precisely according to the example said outgoing shaft portion 11 (outgoing square) 11. Said cremone shaft 11 comprises at its end 111 , opposite its end 112 entering the cremone, an opening bore 110 transverse to the longitudinal axis of said shaft 11, said bore forming a conduit 110 receiving the coupling means 13 which comprises two projecting elements. Said coupling means is constituted according to the example of a round rod of small diameter, such as a pin, the ends of which form said projecting elements. Said coupling rod 13 is made of steel.

En référence aux figures 1 à 7, notamment à la figure 3 en éclaté, ledit support 10 a une forme de cylindre creux. Ledit support comporte ainsi une paroi cylindrique comprenant un évidement intérieur constituant une cavité à section circulaire présentant un orifice d'entrée 102 et un orifice de sortie 101. Ledit orifice entrant 102 est récepteur d'une extrémité 121 de l'arbre de béquille 12 (carré entrant) et ledit orifice sortant 101 récepteur d'une extrémité 111 de l'arbre de crémone 11 (carré sortant). Ladite paroi cylindrique comprend aussi deux ouvertures103, 104 en forme de fentes, traversantes selon la direction radiale de ladite paroi, qui débouchent dans ladite cavité, ou autrement dit ces ouvertures forment deux lumières 103, 104 (Fig. 7). Ces fentes sont de forme oblongue, en arc de cercle selon la direction (circulaire) de la circonférence de ladite paroi cylindrique. Elles sont disposées de manière diamétralement opposées sur la circonférence de ladite paroi, c'est-à-dire qu'elles sont creusées en opposition dans la paroi cylindrique dudit support et en suivant sa circonférence. Ces dites lumières 103, 104 ont la même longueur. Elles sont respectivement réceptrices des extrémités 131, 132 du moyen de couplage 13, ces extrémités formant les éléments en saillie, orientés radialement sur l'arbre de crémone et se logeant respectivement dans lesdites deux lumières103, 104, en entrant depuis la cavité vers l'extérieur de la paroi cylindrique. La longueur dudit moyen de couplage 13 est d'une longueur supérieure au diamètre de ladite cavité et adaptée au diamètre de la paroi cylindrique. En référence à la figure 7 notamment, chaque dite lumière 103, 104 comprend respectivement des extrémités 1031, 1032 et 1041, 1042 formant des butées d'appui pour lesdits éléments en saillie dudit moyen de couplage 13.With reference to figures 1 to 7 , particularly at Figure 3 exploded, said support 10 has the shape of a hollow cylinder. Said support thus comprises a cylindrical wall comprising an interior recess constituting a cavity of circular section having an inlet orifice 102 and an outlet 101. Said inlet orifice 102 receives one end 121 of the crutch shaft 12 ( incoming square) and said outgoing orifice 101 receiving one end 111 of the cremone shaft 11 (outgoing square). Said cylindrical wall also comprises two openings 103, 104 in the form of slots, passing through in the radial direction of said wall, which open into said cavity, or in other words these openings form two lights 103, 104 ( Fig. 7 ). These slots are oblong in shape, in an arc in the (circular) direction of the circumference of said cylindrical wall. They are arranged diametrically opposite on the circumference of said wall, that is to say that they are dug in opposition in the cylindrical wall of said support and following its circumference. These so-called lights 103, 104 have the same length. They respectively receive the ends 131, 132 of the coupling means 13, these ends forming the projecting elements, oriented radially on the cremone shaft and being housed respectively in said two slots 103, 104, entering from the cavity towards the exterior of the cylindrical wall. The length of said coupling means 13 is one length greater than the diameter of said cavity and adapted to the diameter of the cylindrical wall. In reference to the Figure 7 in particular, each said light 103, 104 respectively comprises ends 1031, 1032 and 1041, 1042 forming support stops for said elements projecting from said coupling means 13.

Partant d'une position de verrouillage correspondant à une fermeture verrouillée d'un ouvrant C, en manoeuvrant la béquille 2 suivant une rotation décrivant une première course angulaire d'une amplitude a2, par exemple de 90 degrés, l'arbre de béquille 12 (carré de béquille) entraîne le support 10 en rotation par guidage dans ses lumières 103, 104 autour des éléments en saillie dudit moyen de couplage 13 ( par exemple de la goupille) , comme illustré aux figures 4 et 5, donc en course angulaire inactive c'est-à-dire sans produire d'entrainement de l'arbre de crémone 11 dans la crémone, et ce jusqu'à ce que les éléments en saillie dudit moyen de couplage 13 (la goupille) viennent en appui contre une des butées d'appui 1032, 1042 respectives desdites lumières 103, 104 comme illustré par les figures 6 et 7. En poursuivant la course angulaire de la béquille 2, l'arbre de béquille 12 (carré entrant) et l'arbre de crémone 11 (carré sortant) entrent alors en rotation en décrivant une course angulaire active d'une amplitude angulaire α1, entrainant solidairement la crémone selon la même amplitude angulaire, ledit arbre de crémone 11 étant relié solidairement au fouillot de la crémone.Starting from a locking position corresponding to a locked closure of an opening C, by operating the lever 2 following a rotation describing a first angular stroke of an amplitude a2, for example 90 degrees, the lever shaft 12 ( crutch square) drives the support 10 in rotation by guiding in its slots 103, 104 around the projecting elements of said coupling means 13 (for example of the pin), as illustrated in figures 4 And 5 , therefore in inactive angular stroke, that is to say without producing any drive of the cremone shaft 11 in the cremone, until the projecting elements of said coupling means 13 (the pin) come resting against one of the respective support stops 1032, 1042 of said lights 103, 104 as illustrated by the figures 6 And 7 . By continuing the angular stroke of the crutch 2, the crutch shaft 12 (incoming square) and the cremone shaft 11 (outgoing square) then begin to rotate, describing an active angular stroke of an angular amplitude α1, jointly driving the cremone according to the same angular amplitude, said cremone shaft 11 being integrally connected to the follower of the cremone.

Une fois la course morte réalisée dans lesdites lumières, la goupille 13 en butée contre une des extrémités respectives desdites lumières est ainsi entrée en appui sur le support 10 du convertisseur qui a pu alors transmettre l'effort de couple entre lesdites arbres de béquille 12 et de crémone 11 sur les degrés de course restants (α1) jusqu'à la position de déverrouillage. Par exemple la course angulaire de l'arbre de crémone 11 couvre une amplitude angulaire α1 de 90 degrés, quand la béquille ainsi que l'arbre de béquille décrivent une course angulaire totale θ de 180 degrés (θ étant la somme de α2 et de α1). Ainsi, avec une manoeuvre à 180 degrés de la béquille 2, le fouillot de crémone opère une rotation a1 de 90 degrés seulement. La béquille 2 se retrouve à la verticale suivant un montant de fermeture M et dirigée vers le haut (+Z) quand sa position de départ, pour une position de fermeture verrouillée de l'ouvrant, est à la verticale suivant ledit montant M et dirigée vers le bas (-Z), comme illustré en figure 8.Once the dead stroke has been achieved in said slots, the pin 13 abutting against one of the respective ends of said slots thus came to rest on the support 10 of the converter which was then able to transmit the torque force between said prop shafts 12 and bolt 11 on the remaining degrees of travel (α1) to the unlocking position. For example the angular travel of the cremone shaft 11 covers an angular amplitude α1 of 90 degrees, when the crutch as well as the crutch shaft describe a total angular travel θ of 180 degrees (θ being the sum of α2 and α1 ). Thus, with a 180 degree maneuver of the stand 2, the cremone follower operates a rotation a1 of only 90 degrees. The support 2 is found vertically following a closing amount M and directed towards the top (+Z) when its starting position, for a locked closing position of the sash, is vertical along said amount M and directed downwards (-Z), as illustrated in figure 8 .

La longueur des lumières 103, 104 détermine l'amplitude de la course angulaire morte que l'on souhaite, la position initiale dudit moyen de couplage 13 (goupille) pour laquelle les éléments en saillie sont en appui sur une des butées respectives des lumières 103, 104, correspondant à la position de fermeture verrouillée de l'ouvrant et à une position donnée de la béquille, de préférence à la verticale et vers le bas ( -Z ) suivant le montant de fermeture.The length of the lights 103, 104 determines the amplitude of the dead angular travel that is desired, the initial position of said coupling means 13 (pin) for which the projecting elements are supported on one of the respective stops of the lights 103 , 104, corresponding to the locked closing position of the opening and a given position of the handle, preferably vertically and downwards (-Z) following the closing amount.

Ledit dispositif est réversible, au retour vers la position de verrouillage, lorsqu'on ramène la béquille 2 vers la position verrouillée en la tournant en sens inverse de celui à l'aller opéré lors de la manoeuvre de déverrouillage, l'arbre de béquille 12 est en rotation aussi selon le sens inverse de la course aller et entraîne en rotation le support 10 en course angulaire morte suivant ses dites lumières 103, 104, jusqu'à ce que le moyen de couplage 13 soit en appui contre l'autre extrémité desdites lumières, l'arbre de crémone 11 étant alors entrainé en rotation, et solidairement le fouillot de crémone qui opère une rotation jusqu'à atteindre la position de verrouillage (rotation de 90 degrés).Said device is reversible, on returning to the locking position, when the crutch 2 is brought back to the locked position by turning it in the opposite direction to that in the outward direction operated during the unlocking maneuver, the crutch shaft 12 is also in rotation in the opposite direction of the forward stroke and rotates the support 10 in dead angular stroke along its said slots 103, 104, until the coupling means 13 bears against the other end of said lights, the cremone shaft 11 then being rotated, and integrally the cremone follower which operates a rotation until reaching the locking position (rotation of 90 degrees).

Le convertisseur de course angulaire comprend des moyens d'aide au montage 3, 4 (Fig. 9A) pour le montage du moyen de couplage 13 pour relier le sens du parcours de la fente entre ses deux extrémités au sens de rotation de l'organe de manoeuvre, de sorte que la course angulaire inactive de l'organe de manoeuvre puisse avoir lieu avant la course angulaire active de l'arbre d'actionnement, c'est-à-dire avant que la rotation de l'arbre d'actionnement puisse actionner le déverrouillage ou le verrouillage du système de verrouillage/déverrouillage à crémone. Le sens de rotation de l'organe de manoeuvre est adapté à une ouverture de l'ouvrant vers la gauche ou vers la droite. Selon l'exemple de montage d'un dispositif de commande sur le montant respectifs des deux ouvrants coulissants V, V', installés en chicane l'un par rapport à l'autre, tel qu'illustré par la figure 8, et les figures 9A , 9B et 9C , les moyens d'aide au montage sont des lettres : la lettre D (3) et la lettre G (4), qui sont portées selon l'exemple sur la face externe de la paroi du support et aux extrémités de la fente (ou les fentes) du support 10, pour indiquer où positionner au départ du montage l'élément (ou les éléments) en saillie du moyen de couplage, soit la goupille 13, dans la fente (ou les fentes) du support.The angular stroke converter comprises mounting aid means 3, 4 ( Fig. 9A ) for mounting the coupling means 13 to connect the direction of travel of the slot between its two ends to the direction of rotation of the operating member, so that the inactive angular travel of the operating member can take place before the active angular travel of the actuating shaft, that is to say before the rotation of the actuating shaft can actuate the unlocking or locking of the cremone locking/unlocking system. The direction of rotation of the operating member is adapted to opening the sash to the left or to the right. According to the example of mounting a control device on the respective amount of the two sliding openings V, V', installed in a chicane relative to each other, as illustrated by the figure 8 , and the figures 9A , 9B And 9C , the means of aid to assembly are letters: the letter D (3) and the letter G (4), which are carried according to the example on the external face of the wall of the support and at the ends of the slot (or the slots) of the support 10, for indicate where to position at the start of the assembly the element (or elements) projecting from the coupling means, i.e. the pin 13, in the slot (or slots) of the support.

Selon l'exemple de la baie illustrée figure 8, des étapes de montage de l'organe de manoeuvre 2' pour l'ouvrant coulissant V' se situant sur la droite de l'opérateur regardant vers la baie depuis le côté recevant la poignée de manoeuvre, généralement à l'intérieur d'un bâtiment, sont illustrées aux figures 9A , 9B et 9C. Dans ce cas, la poignée 2' est montée sur le montant de droite M de l'ouvrant et la béquille doit être tournée vers la gauche pour déverrouiller le mécanisme. L'ouvrant étant en position fermeture, la béquille passe d'une position verticale orientée vers le bas à la position verticale orientée vers le haut (en pointillés) pour déverrouiller le mécanisme, et donc en position d'ouverture pour l'ouvrant. Comme illustré sur les figures 9A et 9B, au début du montage de l'organe de manoeuvre, on prépare l'organe de manoeuvre 2' et le convertisseur angulaire 1 : la béquille 20' doit être positionnée à 90 degrés par rapport au montant d'ouvrant M qui comprend la crémone 5, ainsi que le cache 220', qui fermait la semelle 22', est pivoté à 90 degrés. Lorsque l'arbre sortant 11 est installé dans le support 10, on introduit la goupille 13 dans le conduit 110 dudit arbre 11 à travers les fentes 103, 104 dudit support. Une extrémité 131, 132 de la goupille 13 est positionnée respectivement dans les fentes 103, 104 du support 10 en correspondance avec le moyen d'aide au montage 3 représenté par la lettre D, comme l'illustre le détail de la figure 9A zoomant sur le convertisseur angulaire. D est utilisé pour « Droite », la poignée s'installant sur le vantail de droite selon cet exemple. On peut aussi considérer que naturellement, une personne qui veut ouvrir l'ouvrant, utilisera préférentiellement sa main droite pour tourner la béquille, et ainsi que la lettre D correspond à la main utilisée. D'autres conventions peuvent être établies pour faciliter le montage correct de la poignée. Une extrémité 121 de l'arbre entrant 12 ayant été insérée dans le support 10, l'autre extrémité 122 est insérée dans l'orifice de la semelle de poignée 22'.According to the example of the bay shown figure 8 , steps for mounting the operating member 2' for the sliding opening V' located on the right of the operator looking towards the bay from the side receiving the operating handle, generally inside a building, are illustrated in figures 9A , 9B And 9C . In this case, the handle 2' is mounted on the right upright M of the opening and the handle must be turned to the left to unlock the mechanism. With the opening in the closed position, the handle moves from a vertical position facing downwards to the vertical position facing upwards (dotted) to unlock the mechanism, and therefore in the open position for the opening. As illustrated on the figures 9A And 9B , at the start of assembly of the operating member, the operating member 2' and the angular converter 1 are prepared: the lever 20' must be positioned at 90 degrees relative to the opening amount M which includes the cremone bolt 5 , as well as the cover 220', which closed the sole 22', is rotated 90 degrees. When the outgoing shaft 11 is installed in the support 10, the pin 13 is introduced into the conduit 110 of said shaft 11 through the slots 103, 104 of said support. One end 131, 132 of the pin 13 is positioned respectively in the slots 103, 104 of the support 10 in correspondence with the mounting aid means 3 represented by the letter D, as illustrated in the detail of the Figure 9A zooming in on the angle converter. D is used for “Right”, the handle being installed on the right leaf according to this example. We can also consider that naturally, a person who wants to open the opening will preferentially use their right hand to turn the handle, and thus the letter D corresponds to the hand used. Other conventions may be established to facilitate correct mounting of the handle. One end 121 of the incoming shaft 12 having been inserted into the support 10, the other end 122 is inserted into the orifice of the handle sole 22'.

Comme illustré en éclaté par la figure 9B, l'extrémité libre 112 de l'arbre sortant 11 est introduite dans le fouillot de crémone à travers un trou récepteur 50, que comprend le montant récepteur M, en correspondance avec ledit fouillot. On vient alors fixer par vissage l'organe de manoeuvre 2' sur ledit montant récepteur, à l'aide des vis 201', 202' dans les orifices de la semelle prévus à cet effet jusque dans les orifices correspondants du montant récepteur M. Le cache 220' est ensuite remis à la verticale pour fermer ladite semelle.As illustrated exploded by the Figure 9B , the free end 112 of the outgoing shaft 11 is introduced into the cremone follower through a hole receiver 50, which includes the receiver amount M, in correspondence with said follower. The operating member 2' is then fixed by screwing onto said receiving upright, using screws 201', 202' in the orifices in the sole provided for this purpose up to the corresponding orifices in the receiving upright M. The cover 220' is then returned to the vertical to close said sole.

Comme illustré par la figure 9C, on peut alors mettre la béquille 20' à la verticale, en la ramenant de sa position à 90 degrés (en pointillés) vers le bas, pour fermer l'ouvrant V' contre un montant P du dormant, en verrouillant le mécanisme de verrouillage dans ledit montant de dormant P. La béquille a donc fait une rotation de 90 degrés vers le bas. L'extrémité de la goupille qui était positionnée dans la fente au niveau de la lettre D au montage se retrouve au niveau de la lettre G (4) à l'autre extrémité de la fente qui a tourné de 90 degrés quand la poignée est en position de verrouillage.As illustrated by the Figure 9C , we can then put the handle 20' vertically, bringing it back from its 90 degree position (dotted) downwards, to close the opening V' against an upright P of the frame, locking the locking mechanism in said frame amount P. The crutch has therefore rotated 90 degrees downwards. The end of the pin which was positioned in the slot at the letter D during assembly is found at the letter G (4) at the other end of the slot which has rotated 90 degrees when the handle is in position. lock position.

Pour le montage du dispositif sur l'ouvrant de gauche V, non représenté, la goupille 13 sera positionnée sur la lettre G au début du montage, quand la béquille 20 est à 90 degrés. Quand la béquille est rabattue à la verticale vers le bas, les extrémités de la goupille 13 se retrouvent au niveau de la lettre G.For mounting the device on the left opening V, not shown, the pin 13 will be positioned on the letter G at the start of assembly, when the lever 20 is at 90 degrees. When the stand is folded vertically downwards, the ends of pin 13 are at the level of the letter G.

Ledit support et ladite béquille peuvent être formés d'une seule pièce, autrement dit d'une pièce monobloc. Par exemple cette pièce monobloc peut être formée par moulage d'un matériau plastique ou d'un autre matériau, ou par usinage.Said support and said stand can be formed in one piece, in other words a single piece. For example, this one-piece part can be formed by molding a plastic material or another material, or by machining.

Les exemples ont été décrits pour une baie vitrée comprenant un ouvrant coulissant verticalement dans son propre plan et se verrouillant contre un montant de dormant, mais non limitativement de l'invention. En effet l'ouvrant pourrait se verrouiller contre un autre montant tel qu'un autre montant de la baie comme un montant d'un autre vantail ou d'un panneau fixe que comprendrait la baie.The examples have been described for a bay window comprising an opening sliding vertically in its own plane and locking against a frame amount, but not limiting the invention. In fact, the opening could lock against another amount such as another amount of the bay such as an amount of another leaf or a fixed panel that the bay would include.

L'invention a atteint ses objectifs en proposant un dispositif de commande comprenant un convertisseur de course angulaire, compact, se montant en lieu et place de l'arbre d'actionnement usuel d'une poignée de frappe usuelle, ce convertisseur permettant de transformer une course angulaire d'une amplitude donnée de l'organe de manoeuvre, c'est-à-dire de la béquille, en une opération d'actionnement du fouillot de la crémone d'une amplitude angulaire différente de celle de l'organe de manoeuvre, notamment inférieure à ladite amplitude angulaire donnée de la course angulaire de l'organe de manoeuvre. Le convertisseur permet notamment de transformer une course angulaire de 180 degrés de la béquille en une manoeuvre d'un carré de crémone de 90 degrés d'amplitude. En outre ledit dispositif selon l'invention présente une bonne résistance mécanique, notamment une grande résistance au cisaillement.The invention has achieved its objectives by proposing a control device comprising a compact angular stroke converter, mounted in place of the usual actuating shaft of a handle. usual strike, this converter making it possible to transform an angular stroke of a given amplitude of the operating member, that is to say of the crutch, into an operation of actuation of the follower of the cremone of an angular amplitude different from that of the operating member, in particular less than said given angular amplitude of the angular stroke of the operating member. The converter makes it possible in particular to transform an angular travel of 180 degrees of the crutch into an operation of a cremone square of 90 degrees of amplitude. Furthermore, said device according to the invention has good mechanical strength, in particular high shear resistance.

L'invention présente aussi l'avantage de permettre l'utilisation d'une poignée usuelle de frappe sur des menuiseries coulissantes sans risque de collision de la béquille avec le montant chicane et ce sans limiter l'ouverture initiale du vantail portant ladite béquille. L'invention permet donc l'utilisation d'une poignée usuelle de frappe montée en saillie sur un montant de menuiseries coulissantes en conservant une ergonomie adaptée à la manoeuvre des vantaux en translation. Il est possible ainsi d'équiper tout un bâtiment avec des béquilles de même style, que ce soit pour des ouvrants à frappe ou coulissantsThe invention also has the advantage of allowing the use of a usual striking handle on sliding joinery without risk of collision of the lever with the chicane upright and this without limiting the initial opening of the leaf carrying said lever. The invention therefore allows the use of a usual striking handle mounted projecting on an amount of sliding joinery while maintaining ergonomics adapted to the operation of the leaves in translation. It is thus possible to equip an entire building with handles of the same style, whether for striking or sliding openings.

Les fabricants ou les installateurs d'ouvrants notamment coulissants peuvent en particulier employer une poignée usuelle mais présentant une béquille demeurant à la verticale pendant les phases de déplacement du vantail coulissant et compatible avec l'usage d'une crémone usuelle quart de tour.Manufacturers or installers of particularly sliding openings can in particular use a usual handle but having a crutch remaining vertical during the phases of movement of the sliding leaf and compatible with the use of a usual quarter-turn bolt.
