Description

La présente invention se rattache au secteur technique des volets, portes, vantaux et tous supports présentant des lames notamment pour l'orientation de la lumière de type persienne.The present invention relates to the technical sector of shutters, doors, leaves and all supports with blades, in particular for the orientation of the louver type light.

Généralement, les lames sont montées à libre articulation entre les montants de l'ossature support constituant le volet ou autres. L'articulation s'effectue au moyen d'axes transversaux montés en débordement de la partie médiane de chacune des extrémités des lames, ces axes étant montés à libre rotation dans des logements formés dans l'épaisseur des montants considérés. Le plus souvent, les lames sont disposées dans un plan horizontal et parallèlement les unes par rapport aux autres.Generally, the blades are mounted with free articulation between the amounts of the support frame constituting the flap or the like. The articulation is carried out by means of transverse axes mounted in overflow of the middle part of each of the ends of the blades, these axes being mounted for free rotation in housings formed in the thickness of the amounts considered. Most often, the blades are arranged in a horizontal plane and parallel to each other to others.

Le problème posé est de pouvoir orienter simultanément l'ensemble des lames, afin de pouvoir les positionner dans une position horizontale ou sensiblement horizontale correspondant à un passage maximum de lumière ou dans une position de chevauchement partiel, correspondant à une occultation totale avec, éventuellement, la possibilité de positions intermédiaires entre ces deux positions extrêmes. Dans ce but, les lames sont accouplées entre elles par des biellettes articulées reliées à au moins une tringle de commande, assujettie à un organe de manoeuvre, pour être déplacée en translation, en vue de provoquer une orientation concomitante desdites lames.The problem is to be able to orient simultaneously all the blades, so that they can be positioned in one position horizontal or substantially horizontal corresponding to a passage maximum light or in a partially overlapping position, corresponding to a total occultation with, possibly, the possibility of intermediate positions between these two extreme positions. For this purpose, the blades are coupled together by connecting rods articulated connected to at least one control rod, subject to a operating member, to be moved in translation, in order to cause a concomitant orientation of said blades.

Actuellement, les solutions proposées au niveau de l'organe de manoeuvre permettant la commande en translation de la ou des tringles de commande, ne donnent pas totalement satisfaction. Currently, the solutions proposed at the organ level maneuver allowing the control in translation of the rod (s) not fully satisfactory.

Par exemple, dans une forme de réalisation simplifiée, la ou les tringles de commande, sont actionnées par un système de leviers articulés formant genouillère et accouplés, avec capacité d'articulation, sur une partie de l'ossature. Un basculement angulaire du système de leviers articulés, provoque le déplacement en translation de la ou des tringles de commande.For example, in a simplified embodiment, the one or more control rods, are operated by a system of levers articulated forming a kneepad and coupled, with articulation capacity, on part of the frame. Angular tilting of the articulated levers, causes the translational displacement of the one or more control rods.

Par contre, aucun moyen n'est prévu pour assurer le blocage du système de leviers dans la position d'orientation souhaitée des lames.On the other hand, no means is provided for blocking the lever system in the desired orientation position of the blades.

Cet état de la technique peut être illustré par l'enseignement du brevet CH 220 149.This state of the art can be illustrated by the teaching of Patent CH 220 149.

A partir de cette conception de base, pour assurer le blocage en position angulaire souhaitée des lames, on a proposé d'équiper le système de leviers articulés faisant office de genouillère, d'un organe poussoir apte à assurer un tel blocage. Cette solution technique est relativement compliquée et surtout nécessite l'utilisation des deux mains, l'une pour agir sur un organe poussoir, l'autre pour manoeuvrer angulairement le système de leviers avec des risques de pincements.From this basic design, to ensure blocking in desired angular position of the blades, it has been proposed to equip the articulated lever system acting as a knee switch, an organ pusher capable of ensuring such blocking. This technical solution is relatively complicated and above all requires the use of both hands, one to act on a pusher organ, the other to maneuver angularly the lever system with risks of pinching.

Toujours pour assurer ce blocage dans la position angulaire souhaitée, de l'orientation des lames, on a proposé des agencements sous forme de cliquet et crémaillère. Là encore, la solution n'est pas satisfaisante, étant donné qu'il n'y a pas de réelle sécurité en position ouverte des lames, au motif qu'un appui exercé sur la tringle de commande, par exemple, provoque la fermeture des lames.Always to ensure this blocking in the angular position desired, the orientation of the blades, we proposed arrangements in the form of a ratchet and rack. Again, the solution is not satisfactory, since there is no real security in position open blades, on the ground that a pressure exerted on the rod command, for example, causes the blades to close.

Le brevet US 3 954 023 divulgue un système de commande de l'orientation des lames au moyen d'un levier assujetti, à l'une de ses extrémités, à un élément denté coopérant avec une denture complémentaire d'un système de biellettes articulées à une tringle de commande où sont montées, avec capacité d'orientation angulaire, les différentes lames. Les éléments dentés permettent d'obtenir un blocage en position. Toutefois, il n'est pas possible de débrayer à volonté ce système de denture, pour passer rapidement d'une position extrême de totale ouverture à une position d'orientation partielle, par simple pivotement, et cela d'une seule main.US Patent 3,954,023 discloses a control system for the orientation of the blades by means of a lever secured to one of its ends, to a toothed element cooperating with a toothing complementary to a system of rods hinged to a rod control where are mounted, with angular orientation capacity, the different blades. The toothed elements provide a blockage in position. However, it is not possible to disengage at will this toothing system, to quickly move from an extreme position of total opening to a partial orientation position, by simple swiveling, with just one hand.

L'invention s'est fixée pour but de remédier à ces inconvénients, de manière simple, sûre, efficace et rationnelle.The object of the invention is to remedy these drawbacks, in a simple, safe, efficient and rational way.

Le problème que se propose de résoudre l'invention est de pouvoir assurer d'une seule main, la commande en orientation de l'ensemble des lames avec la possibilité d'assurer automatiquement leur blocage dans des positions angulaires préétablies.The problem which the invention proposes to solve is to ability to operate with one hand control in orientation of all the blades with the possibility of automatically ensuring their locking in pre-established angular positions.

Pour résoudre un tel problème, il a été conçu et mis au point un dispositif d'orientation de lames de volets conforme aux caractéristiques de la revendication 1.To solve such a problem, it was designed and developed a shutter blade orientation device conforming to the characteristics of claim 1.

Compte tenu de ces caractéristiques, on obtient le libre pivotement angulaire des lames, depuis une position maximum d'ouverture jusqu'à une position fermée d'occultation, ainsi que leur orientation selon des positions angulaires prédéterminés.Given these characteristics, we get the free angular pivoting of the blades, from a maximum position opening to a closed concealment position, as well as their orientation according to predetermined angular positions.

Les leviers sont articulés entre deux flasques verticaux d'une platine support constituant le corps de l'organe de verrouillage, ladite platine étant articulée sur la partie de l'ossature. The levers are articulated between two vertical flanges of a support plate constituting the body of the locking member, said plate being articulated on the part of the framework.

Pour résoudre le problème posé de pouvoir manoeuvrer d'une seule main l'organe de commande, le levier de verrouillage et la platine support, sont articulés sur un axe commun monté dans une chape solidaire de l'ossature.To solve the problem of being able to maneuver a single-handed operation of the control unit, the locking lever and the support plate, are articulated on a common axis mounted in a yoke attached to the frame.

Pour résoudre le problème posé de permettre d'orienter angulairement les lames selon la position choisie, le levier de verrouillage comporte un logement pour le montage de l'élément de rappel élastique sous forme d'un ressort en appui sur la base de la platine support articulée, pour mettre en prise, d'une manière permanente, la dent avec le secteur denté, tandis qu'un effort de pression exercé sur ledit levier permet à ladite dent d'échapper la denture du secteur du levier d'accouplement.To solve the problem posed of allowing to orient angularly the blades according to the chosen position, the lever locking includes a housing for mounting the element of elastic return in the form of a spring resting on the base of the articulated support plate, to engage, in a way permanent, the tooth with the toothed sector, while a pressure effort exerted on said lever allows said tooth to escape the toothing of the sector of the coupling lever.

Avantageusement, le levier d'accouplement présentant le secteur denté, est articulé entre les flasques de la platine au moyen d'un axe transversal situé à l'opposé de l'axe commun d'articulation. Le secteur denté est formé sur une partie de circonférence, en bout du levier, et concentriquement à son axe d'articulation.Advantageously, the coupling lever presenting the sector toothed, is articulated between the flanges of the plate by means of an axis transverse located opposite the common axis of articulation. The area toothed is formed on a part of the circumference, at the end of the lever, and concentrically to its axis of articulation.

Pour résoudre le problème posé de pouvoir agir sur le levier de verrouillage d'une manière simultanée au basculement, dans un sens ou dans l'autre, de l'organe de main d'oeuvre et cela d'une seule main, l'extrémité libre de la platine support et de levier de verrouillage, sont recourbées d'une manière ergonomique pour permettre d'agir d'une seule main sur ledit levier de verrouillage.To solve the problem of being able to act on the lever lock simultaneously with tilting, in one direction or in the other, of the labor organ and that with one hand, the free end of the support plate and locking lever, are curved in an ergonomic way to allow to act in a one hand on said locking lever.

    • On a illustré figure 1, d'une manière schématique, une ossature (O) correspondant, par exemple, à celle d'un volet. Cette ossature (O) présente une ouverture (O1) délimitant deux montants verticaux (A) et (B) entre lesquels sont montées, au moyen d'axes tourillons (t), à libre articulation, des lames (L). Les lames (L) sont accouplées entre elles par des biellettes articulées (a) reliées à une tringle de commande (b) assujettie à un organe de commande (C) pour provoquer l'orientation concomitante des lames (L) depuis une position sensiblement horizontale (figures 1, 2 et 3), correspondant à une ouverture maximum, jusqu'à une position de chevauchement partiel (figures 4, 5 et 6), correspondant à une occultation totale de l'ouverture (O1).Illustrated in Figure 1, schematically, a frame (O) corresponding, for example, to that of a shutter. This framework (O) has an opening (O1) defining two vertical uprights (A) and (B) between which are mounted, by means of pins (t), free joint, blades (L). The blades (L) are coupled together by articulated links (a) connected to a control rod (b) subject to a control member (C) to cause orientation concomitant of the blades (L) from a position substantially horizontal (Figures 1, 2 and 3), corresponding to a maximum opening, to a partially overlapping position (Figures 4, 5 and 6), corresponding to a total occultation of the opening (O1).

    L'organe de manoeuvre comprend une platine support (1) articulée au moyen d'un axe transversal (2) dans une chape (3) fixée sur une partie de l'ossature (O). La platine support présente deux flasques verticaux (1a) (1b) établis à partir d'une embase commune (1c). Entre les deux flasques (1a) et (1b) est monté un levier de verrouillage (4). L'une des extrémités du levier (4) présente un nez (4a) pour être articulé sur l'axe d'articulation (2) de la platine support (1). Autrement dit, la platine support (1) et le levier de verrouillage (4) sont articulés sur un axe commun, en l'espèce, l'axe transversal (2) monté dans la chape (3).The operating member comprises a support plate (1) articulated by means of a transverse axis (2) in a yoke (3) fixed on part of the framework (O). The support plate has two flanges vertical (1a) (1b) established from a common base (1c). Between the two flanges (1a) and (1b) is mounted a locking lever (4). One end of the lever (4) has a nose (4a) to be articulated on the hinge pin (2) of the support plate (1). In other words, the support plate (1) and the locking lever (4) are articulated on a common axis, in this case, the transverse axis (2) mounted in the yoke (3).

    Le corps du levier de verrouillage (4), de section méplate, présente en débordement de sa face de dessus, au moins une dent (4b) apte à engrener avec une denture (5a) d'un levier d'accouplement (5). La denture (5a) est formée à l'une des extrémités du levier (5) et sur une partie de circonférence formée concentriquement à un axe d'articulation (6) monté entre les deux flasques (1a) et (1b) de la platine support (1), à l'opposé de l'axe commun d'articulation (2).The body of the locking lever (4), of flat section, has an overflow from its top face, at least one tooth (4b) able to mesh with a toothing (5a) of a coupling lever (5). The teeth (5a) are formed at one end of the lever (5) and on a part of the circumference formed concentrically with an axis of articulation (6) mounted between the two flanges (1a) and (1b) of the support plate (1), opposite the common axis of articulation (2).

    L'autre extrémité du levier (5), qui présente une forme générale coudée, est articulée, en (5b), à l'extrémité de la barre de commande correspondante (b). The other end of the lever (5), which has a general shape angled, is articulated, at (5b), at the end of the control bar corresponding (b).

    Pour mettre en position d'engrènement permanent la dent (4b) avec la denture (5a), le levier de verrouillage (4) est assujetti à un élément élastique de rappel sous forme d'un ressort (7) logé dans un chambrage d'un bossage (4c) formé en débordement de la face du levier de verrouillage (4) présentant la dent (4b). Ce ressort de rappel (7) est en appui sur l'embase (1c) de la platine support (1). Dans cette position d'engrènement (figure 12), le levier de verrouillage (4) est disposé angulairement par rapport à l'embase (1c) de sorte qu'un effort de pression exercé sur ce dernier comprime le ressort (7), de sorte que la dent (4b) échappe la denture (5a) du levier d'accouplement (5).To put the tooth (4b) in permanent engagement position with the teeth (5a), the locking lever (4) is subject to a elastic return element in the form of a spring (7) housed in a recess of a boss (4c) formed in overflow from the face of the lever locking (4) having the tooth (4b). This return spring (7) is in support on the base (1c) of the support plate (1). In this position meshing (Figure 12), the locking lever (4) is arranged angularly relative to the base (1c) so that an effort of pressure exerted on the latter compresses the spring (7), so that the tooth (4b) escapes the teeth (5a) of the coupling lever (5).

    Le montage articulé du levier d'accouplement (5) par rapport à la tringle de commande (b) et par rapport à la platine support (1), elle même articulée avec le levier de verrouillage (4) sur l'ossature (O), constitue un système à genouillère. Il en résulte qu'un effet de pivotement angulaire de l'organe de manoeuvre par rapport à l'axe commun (2), dans un sens ou dans l'autre, provoque le déplacement en translation, également dans un sens ou dans l'autre, de la tringle de commande (b) et, d'une manière concomitante, l'orientation angulaire des lames (L). On renvoie aux figures 2 et 5 notamment.The articulated mounting of the coupling lever (5) relative to the control rod (b) and relative to the support plate (1), it even articulated with the locking lever (4) on the frame (O), constitutes a toggle system. It follows that an effect of angular pivoting of the actuator relative to the axis common (2), in one direction or the other, causes displacement in translation, also in one direction or the other, of the rod command (b) and, concomitantly, the angular orientation blades (L). We refer to Figures 2 and 5 in particular.

    Compte tenu des caractéristiques à la base de l'invention, pour manoeuvrer angulairement d'une seule main l'organe de manoeuvre (C) incluant notamment la platine support (1) et le levier de verrouillage (4), il suffit de tenir les extrémités libres de ladite platine (1) et dudit levier (4) qui sont recourbées respectivement, d'une manière ergonomique, en (1d) et (4d). Given the characteristics underlying the invention, for angularly maneuver with one hand the operating member (C) including in particular the support plate (1) and the locking lever (4), just hold the free ends of said plate (1) and said lever (4) which are curved respectively, in an ergonomic manner, in (1d) and (4d).

    Comme indiqué, lorsque l'on appui sur le levier de verrouillage (4), la dent (4b) échappe la denture (5a), permettant, toujours avec la même main, de basculer dans un sens ou dans l'autre, la platine support (1). Lorsque l'orientation angulaire des lames est souhaitée, il suffit de relâcher le levier de verrouillage (4), qui, sous l'effet de détente de son ressort (7) vient par sa dent (1b) en prise avec la denture (5a) assurant ainsi 1e blocage. Le nombre de dents de la denture (5a) détermine par conséquent, le nombre de position angulaire des lames. Bien évidemment, pour passer des deux positions extrêmes de totale ouverture (figure 1) à la position de chevauchement partiel (figure 4), il suffit de maintenir en pression le levier de verrouillage (4) pour libérer le système de denture (4b-5a).As shown, when the locking lever is pressed (4), the tooth (4b) escapes the toothing (5a), allowing, always with the same hand, tilt in one direction or the other, the support plate (1). When the angular orientation of the blades is desired, it suffices to release the locking lever (4), which, under the effect of relaxation of its spring (7) comes by its tooth (1b) in engagement with the toothing (5a) ensuring thus blocking. The number of teeth in the teeth (5a) determined by Therefore, the number of angular position of the blades. Well obviously to go from the two extreme positions of total opening (Figure 1) at the partial overlap position (Figure 4), it just keep the locking lever (4) pressed to release the toothing system (4b-5a).

    Bien évidemment, les éléments constitutifs du dispositif, notamment au niveau de l'organe de manoeuvre, peuvent être réalisés en toutes dimensions et en tous matériaux.Obviously, the components of the device, in particular at the level of the operating member, can be carried out in all sizes and in all materials.
