Description

La présente invention est relative aux dispositifs d'actionnement de volet ou analogue, permettant d'ouvrir et fermer un volet, en particulier un volet d'exutoire de fumée.The present invention relates to shutter actuating devices or the like, for opening and closing a shutter, in particular a smoke outlet flap.

Les dispositifs d'actionnement de volet connus offrent en général un angle d'ouverture relativement faible, inférieur à 90°. Certains dispositifs d'actionnement connus offrent certes un angle d'ouverture élevé, jusqu'à 170° voire 180°, mais ils sont d'une conception complexe impliquant de nombreux composants.Known shutter actuators generally provide a relatively small opening angle of less than 90 °. Some known actuators offer a high opening angle, up to 170 ° or 180 °, but they are of a complex design involving many components.

Un tel dispositif d'actionnement, de conception complexe, est par exemple décrit dans le brevet EP 0 443 050, dans lequel le volet est monté pivotant, autour d'un axe de rotation fixe, sur un côté d'un cadre, entre une position d'ouverture maximale et une position fermée, le dispositif comportant un actionneur linéaire articulé, d'une part, en un emplacement du volet éloigné de son axe de rotation sur le cadre, et d'autre part, autour d'un axe d'appui monté à une première extrémité mobile d'un levier d'appui, lequel est monté pivotant autour d'un axe de bascule solidaire dudit côté du cadre, par une seconde extrémité fixe opposée à la première, à proximité de l'axe de rotation du volet.Such an actuating device, of complex design, is for example described in patent EP 0 443 050, in which the flap is pivotally mounted, about a fixed axis of rotation, on one side of a frame, between a maximum open position and a closed position, the device comprising an articulated linear actuator, on the one hand, at a location of the shutter remote from its axis of rotation on the frame, and on the other hand, around an axis of support mounted at a first movable end of a support lever, which is pivotally mounted about a rocker axis integral with said frame side, by a second fixed end opposite the first, close to the axis of shutter rotation.

Ce dispositif d'actionnement de volet fait appel à de nombreux composants, notamment un levier supplémentaire d'articulation, qui le rendent complexe à assembler et à monter. Ce dispositif d'actionnement est également encombrant, en particulier du fait des leviers d'appui et d'articulation qui dépassent en arrière du cadre de sorte que, durant l'ouverture ou la fermeture du volet, ils peuvent cogner contre des objets avoisinants.This flap actuation device utilizes many components, including an additional hinge lever, which makes it complex to assemble and assemble. This actuating device is also bulky, in particular because of the support levers and articulation that protrude behind the frame so that, during the opening or closing of the flap, they can bump against neighboring objects.

La présente invention vise à surmonter ces inconvénients en proposant un dispositif d'actionnement de volet qui soit compact, d'une conception simple facilitant son assemblage et son montage, et qui permette d'ouvrir un volet jusqu'à un angle de 170°, voire 180°, sans dépasser en arrière du cadre durant l'ouverture ou la fermeture du volet.The present invention aims to overcome these disadvantages by providing a shutter actuating device which is compact, of simple design facilitating its assembly and assembly, and which allows to open a flap up to an angle of 170 °, even 180 °, without going beyond the frame during the opening or closing of the shutter.

A cet effet, l'invention a pour objet un dispositif d'actionnement d'un volet, du genre précité, dans lequel le levier d'appui comprend deux ailes latérales situées de part et d'autre de l'actionneur linéaire et reliées, au moins au voisinage de l'axe de bascule, par une pièce formant berceau destinée à recevoir l'actionneur linéaire au-delà d'une position d'ouverture intermédiaire du volet, à partir de laquelle le levier d'appui quitte une position de butée de sa première extrémité mobile contre l'intérieur dudit côté du cadre, et pivote autour de son axe de bascule.For this purpose, the subject of the invention is a device for actuating a flap, of the aforementioned type, in which the support lever comprises two lateral wings located on either side of the linear actuator and connected, at least in the vicinity of the rocker axis, by a cradle member for receiving the linear actuator beyond an intermediate opening position of the flap, from which the support lever leaves a position of stop of his first end movable against the inside of said frame side, and pivots about its rocking axis.

Ainsi, le dispositif d'actionnement de volet selon l'invention comporte un unique levier d'appui dont la configuration en berceau avec des ailes latérales, prévue pour recevoir un actionneur linéaire, lui permet de ne pas dépasser en arrière du cadre pendant les mouvements d'ouverture et de fermeture du volet, tout en assurant, en fonction de l'angle d'ouverture du volet, un déplacement d'un point virtuel d'articulation de l'actionneur linéaire sur le cadre qui autorise d'ouvrir le volet jusqu'à un angle de 170° voire 180°.Thus, the shutter actuation device according to the invention comprises a single support lever whose cradle configuration with side wings, designed to receive a linear actuator, allows it to not protrude behind the frame during the movements. opening and closing the shutter, while ensuring, depending on the opening angle of the shutter, a displacement of a virtual pivot point of the linear actuator on the frame that allows to open the shutter up to an angle of 170 ° or 180 °.

Le dispositif d'actionnement est d'une conception simple qui facilite son assemblage et son montage contre un bord fixe du cadre. Son montage ne nécessite pas l'emploi d'une traverse qui gênerait le passage. Appliquée à un exutoire de fumée, l'invention permet donc d'optimiser le débit de fumée qui s'échappe.The actuator is of simple design which facilitates its assembly and mounting against a fixed edge of the frame. Its assembly does not require the use of a crossbar that would hinder the passage. Applied to a smoke outlet, the invention thus optimizes the flow of smoke that escapes.

L'actionneur linéaire peut être un vérin, notamment à double effet, commandé à distance.The linear actuator may be a cylinder, in particular double-acting, controlled remotely.

Dans un souci de compacité du dispositif d'actionnement, par rapport à la hauteur du cadre, la distance entre l'axe de bascule et l'axe d'appui est avantageusement inférieure ou égale à la hauteur du cadre.For the sake of compactness of the actuating device, relative to the height of the frame, the distance between the rocker axis and the support axis is advantageously less than or equal to the height of the frame.

Les ailes latérales du levier d'appui peuvent être articulées, autour de l'axe de bascule, entre deux ailes de support montées à l'intérieur dudit côté du cadre. Les ailes de support permettent de décaler sensiblement l'axe de bascule vers l'intérieur du cadre, et ainsi d'ajuster l'angle maximal d'ouverture du volet.The lateral wings of the support lever can be articulated, around the rocker axis, between two support wings mounted inside said side of the frame. The support wings can substantially shift the axis of rocking towards the inside of the frame, and thus adjust the maximum opening angle of the flap.

En fonctionnement normal du dispositif d'actionnement de volet, le mouvement d'ouverture maximale du volet est limité par la fin de course de l'actionneur linéaire. Néanmoins, pour sécuriser le dispositif d'actionnement en cas de fonctionnement anormal, notamment provoqué par une force extérieure non désirée exercée sous l'actionneur linéaire, chaque aile de support présente avantageusement un moyen de retenue des ailes latérales du levier d'appui, réalisé notamment sous la forme d'un pli ménagé à une extrémité vers l'intérieur du cadre, à proximité et au-delà de l'axe de bascule, et orienté vers l'aile de support adjacente. Cette disposition permet d'éviter que l'actionneur linéaire sorte du berceau formé par le levier d'appui et que le dispositif d'actionnement de volet bascule de manière irréversible et s'ouvre d'un angle supérieur à 180°, risquant d'endommager le volet.In normal operation of the shutter actuation device, the maximum opening movement of the shutter is limited by the limit switch of the linear actuator. Nevertheless, in order to secure the actuating device in the event of abnormal operation, in particular caused by an undesired external force exerted under the linear actuator, each support wing advantageously has a means for retaining the lateral wings of the support lever, realized in particular in the form of a fold formed at one end towards the inside of the frame, near and beyond the rocker axis, and oriented towards the adjacent support wing. This arrangement makes it possible to prevent the linear actuator from leaving the cradle formed by the support lever and that the shutter actuating device irreversibly tilts and opens at an angle greater than 180 °, risking to damage the shutter.

Le dessin, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer.The drawing, given by way of example, will provide a better understanding of the invention, the characteristics that it presents and the advantages that it is likely to provide.

La figure 1 est une vue d'un volet, dans son plan de pivotement, équipé d'un dispositif d'actionnement selon l'invention.Figure 1 is a view of a shutter, in its pivot plane, equipped with an actuating device according to the invention.

La figure 2 représente, en perspective, une partie du dispositif d'actionnement de la figure 1.FIG. 2 represents, in perspective, a part of the actuating device of FIG. 1.

La figure 3 est une vue similaire à la figure 2 en position d'ouverture maximale du volet.Figure 3 is a view similar to Figure 2 in the maximum open position of the flap.

La figure 4 est une vue en coupe selon IV-IV de la figure 3.FIG. 4 is a sectional view along IV - IV of FIG. 3.

On a représenté en figures 1 à 4 un dispositif d'actionnement d'un volet d'exutoire de fumée 4.FIGS. 1 to 4 show a device for actuating a smoke outlet flap 4.

Comme indiqué sur la figure 1, le volet 4 est monté pivotant, autour d'un axe de rotation 10 fixe, sur un côté 8a d'un cadre 8, entre une position d'ouverture maximale représentée en traits pleins, une position d'ouverture intermédiaire et une position fermée représentées en traits mixtes.As shown in FIG. 1, the flap 4 is pivotally mounted about a fixed axis of rotation on a side 8a of a frame 8 between a maximum open position shown in solid lines, a position of intermediate opening and a closed position shown in phantom.

Le cadre 8 est en position horizontale, ou en position verticale avec l'axe de rotation du volet 4 au dessus du cadre 8, ou dans une position intermédiaire entre les positions horizontale et verticale.The frame 8 is in a horizontal position, or in a vertical position with the axis of rotation of the flap 4 above the frame 8, or in an intermediate position between the horizontal and vertical positions.

Le dispositif d'actionnement comporte un unique vérin 1 à double effet, commandé à distance, et dont la tige 6 est articulée sur le volet 4, autour d'un axe de rotation 5 éloigné de l'axe de rotation 10 du volet 4 sur le cadre 8.The actuating device comprises a single jack 1 double effect, remotely controlled, and whose rod 6 is articulated on the flap 4, about an axis of rotation 5 away from the axis of rotation 10 of the flap 4 on the frame 8.

Le vérin 1 est également articulé autour d'un axe d'appui 3 monté à une première extrémité mobile d'un levier d'appui 2. Le levier d'appui 2 est monté pivotant par une seconde extrémité fixe opposée à la première, autour d'un axe de bascule 9 solidaire du côté 8a du cadre 8, à proximité de l'axe de rotation 10 du volet 4. La distance, entre l'axe de bascule 9 et l'axe d'appui 3, est sensiblement inférieure à la hauteur du cadre 8.The jack 1 is also articulated about a bearing pin 3 mounted at a first movable end of a support lever 2. The support lever 2 is pivotally mounted by a second fixed end opposite the first, around a rocker axis 9 secured to the side 8a of the frame 8, close to the axis of rotation 10 of the flap 4. The distance between the rocker axis 9 and the bearing axis 3 is substantially less at frame height 8.

Le levier d'appui 2 comprend deux ailes latérales 2a et 2b situées de part et d'autre du vérin 1, et articulées autour de l'axe de bascule 9 entre deux équerres de support 7a, 7b montées à l'intérieur du côté 8a du cadre 8. Les deux ailes 2a et 2b sont reliées, au voisinage de l'axe de bascule 9, par une pièce 2c formant berceau pour le vérin 1 (voir figures 2 et 4).The support lever 2 comprises two lateral wings 2a and 2b located on either side of the jack 1, and hinged about the rocker axis 9 between two support brackets 7a, 7b mounted inside the side 8a. 8. The two wings 2a and 2b are connected, in the vicinity of the rocker axis 9, by a part 2c forming a cradle for the cylinder 1 (see Figures 2 and 4).

Les équerres 7a et 7b permettent de décaler sensiblement l'axe de bascule 9 vers l'intérieur du cadre 8, et d'ajuster ainsi l'angle maximal d'ouverture du volet 4. L'angle maximal d'ouverture obtenu sur la figure 1 est de 150°, mais un angle supérieur, jusqu'à environ 170°, peut être facilement obtenu en changeant la position des axes 3, 5 et 9.The brackets 7a and 7b make it possible to substantially shift the rocker axis 9 towards the inside of the frame 8, and thus to adjust the maximum opening angle of the shutter 4. The maximum opening angle obtained in FIG. 1 is 150 °, but a higher angle, up to about 170 °, can be easily obtained by changing the position of the axes 3, 5 and 9.

En fonctionnement normal du dispositif d'actionnement de volet selon l'invention, le mouvement d'ouverture maximale du volet 4 (voir figures 3 et 4) est limité par la fin de course du vérin 1. Néanmoins, pour sécuriser le dispositif d'actionnement en cas de fonctionnement anormal, notamment provoqué par une force extérieure non désirée exercée sous le vérin 1, chaque équerre de support 7a, 7b présente un pli 12a, 12b de retenue des ailes latérales 2a, 2b du levier d'appui 2.In normal operation of the shutter actuation device according to the invention, the maximum opening movement of the shutter 4 (see FIGS. 3 and 4) is limited by the end of travel of the cylinder 1. Nevertheless, to secure the device of FIG. actuation in the event of abnormal operation, in particular caused by an unwanted external force exerted under the jack 1, each support bracket 7a, 7b has a fold 12a, 12b for retaining the lateral wings 2a, 2b of the support lever 2.

Comme le montrent les figures 2 et 3, le pli 12a, 12b est ménagé à une extrémité de l'équerre de support correspondante 7a, 7b vers l'intérieur du cadre 8, à proximité et au-delà de l'axe de bascule 9, et orienté vers l'équerre de support adjacente 7b, 7a. Cette disposition permet d'éviter que le vérin 1 sorte du berceau 2c formé par le levier d'appui 2 et que le dispositif d'actionnement de volet selon l'invention bascule de manière irréversible et s'ouvre d'un angle supérieur à 180°, risquant d'endommager le volet 4.As shown in Figures 2 and 3, the fold 12a, 12b is formed at one end of the corresponding support bracket 7a, 7b towards the inside of the frame 8, near and beyond the axis of rocker 9 and oriented toward the adjacent support bracket 7b, 7a. This arrangement makes it possible to prevent the jack 1 from coming out of the cradle 2c formed by the support lever 2 and the shutter actuation device according to the invention irreversibly rocking and opening at an angle greater than 180 °, which could damage the flap 4.

Le mouvement d'ouverture du volet 4 s'effectue en trois phases.The opening movement of the flap 4 takes place in three phases.

En premier lieu, le vérin 1, durant la sortie de sa tige 6, s'appuie sur l'intérieur du côté du cadre 8 et pivote par rapport à son axe d'appui 3, ce qui a pour conséquence d'ouvrir partiellement le volet 4. Le levier d'appui 2, sollicité en traction, est fixe et empêche l'axe 3 du vérin 1 de glisser sur l'intérieur du côté 8a du cadre 8.First, the cylinder 1, during the output of its rod 6, is supported on the inside of the side of the frame 8 and pivots with respect to its support axis 3, which has the effect of partially opening the 4. The support lever 2, biased in traction, is fixed and prevents the axis 3 of the cylinder 1 from sliding on the inside of the side 8a of the frame 8.

Lorsque l'axe principal du vérin 1 se trouve dans un plan formé par les deux axes 3 et 9 du levier d'appui 2, le volet 4 occupe une position d'ouverture intermédiaire (voir figure 1) dans laquelle l'axe d'appui 3 quitte le contact avec l'intérieur du cadre 8 et le vérin 1 pivote autour de l'axe de bascule 9 du levier d'appui 2, ce dernier étant toujours sollicité en traction.When the main axis of the jack 1 is in a plane formed by the two axes 3 and 9 of the support lever 2, the flap 4 occupies an intermediate open position (see FIG. 1) in which the axis of support 3 leaves the contact with the inside of the frame 8 and the cylinder 1 pivots about the rocker axis 9 of the support lever 2, the latter always being biased in traction.

Lorsque le centre de gravité du volet 4 passe au-delà de son axe avec le cadre 8, le vérin 1 vient en appui contre le berceau 2c du levier d'appui 2. Ce dernier est alors sollicité en compression et retient le vérin 1 qui, lui-même, retient le volet 4 dans la fin du mouvement d'ouverture. Le mouvement de fermeture s'effectue inversement au mouvement d'ouverture.When the center of gravity of the flap 4 passes beyond its axis with the frame 8, the cylinder 1 bears against the cradle 2c of the support lever 2. The latter is then urged into compression and holds the cylinder 1 which , itself, holds the flap 4 in the end of the opening movement. The closing movement is reversed to the opening movement.

On voit que le dispositif d'actionnement selon l'invention est d'une conception simple ne faisant appel qu'à un seul levier 2 dont la configuration en berceau est étudiée pour ne pas dépasser en arrière du cadre 8 pendant les mouvements d'ouverture et de fermeture du volet 4. Le dispositif d'actionnement présente aussi un faible encombrement en hauteur par rapport au cadre 8.It can be seen that the actuating device according to the invention is of a simple design using only one lever 2, the cradle configuration of which is designed so as not to project beyond the frame 8 during the opening movements. and closing shutter 4. The device actuation also has a small overall height in relation to the frame 8.

Les efforts impliqués dans les éléments avoisinants sont inférieurs à ceux impliqués par les dispositifs de l'art antérieur.The efforts involved in the neighboring elements are less than those involved in the devices of the prior art.

Enfin, le dispositif d'actionnement ne nécessite pas de traverse pour sa fixation, et peut donc se fixer directement sur la costière ou bord fixe du cadre 8.
