Abstract

Device for opening and closing a shutter of a building aperture. It comprises a pneumatic spring 3 articulated on the shutter 1 on the one hand and on the fixed frame of the aperture on the other hand; the spring, taking effect by extension, forms a motor displacing the shutter.

Description

Les volets d'occultation de baies telles que portes et fenêtres sont généralement manoeuvrés à la main pour leur ouverture et leur fermeture. En position fermée, ils doivent être maintenus par un verrou convenable, En position ouverte, ils doivent être également bloqués pour éviter entre actionnés par le vent. The blackout shutters such as doors and windows are generally operated by hand to open and close them. In the closed position, they must be held by a suitable latch, In the open position, they must also be locked to avoid between being actuated by the wind.

Les dispositifs de blocage sont le plus souvent d'un emploi incommode car ils obligent à se pencher par la fenêtre pour les atteindre. Locking devices are most often inconvenient to use because they force them to lean out of the window to reach them.

On connatt autre part les ressorts pneumatiques qui sont utilisés dans l'industrie automobile pour équilibrer le poids des portes de coffres, des hayons ou des capots de moteurs. Ces ressorts, qui sont remplis d'un gaz à haute pression, comportent un piston coulissant dans un cylindre et fixé sur une tige qui sort du cylindre à l'une de ses extrémités. Un passage calibré, contrtlé ou non par une soupape, est prévu dans le piston pour permettre un passage lent et contrôlé du gaz sous pression à travers le piston.Comme l'effort de la pression du gaz sur la face du piston qui est opposée à la tige est prépondérant par rapport à l'effort exercé par cette pression sur l'autre face du piston, dont la section est diminuée de celle de la tige, le piston tend toujours à se déplacer dans le sens de l'extension de l'appareil.  We also know the pneumatic springs which are used in the automotive industry to balance the weight of trunk doors, tailgates or engine covers. These springs, which are filled with a high pressure gas, comprise a piston sliding in a cylinder and fixed on a rod which leaves the cylinder at one of its ends. A calibrated passage, controlled or not by a valve, is provided in the piston to allow a slow and controlled passage of the gas under pressure through the piston. As the effort of the pressure of the gas on the face of the piston which is opposite the rod is preponderant compared to the force exerted by this pressure on the other face of the piston, whose section is reduced by that of the rod, the piston always tends to move in the direction of the extension of the apparatus.

La présente invention a pour objet l'application d'un tel ressort pneumatique à la fermeture et à l'ouverture de volets de baies, application qui fait du ressort pneumatique, non seulement un moteur pour l'ouverture et la fermeture des volets, mais encore un bloqueur des volets dans leur position finale. The subject of the present invention is the application of such an air spring to the closing and opening of bay shutters, an application which makes the air spring not only a motor for opening and closing the shutters, but another blocker of the flaps in their final position.

Le ressort pneumatique afférent à un volet est articulé d'une part sur ce volet et, d'autre part, sur le bati de la baie et l'articulation sur le volet est placée à une certaine distance de l'articulation du volet lui-même sur le cadre de la baie, de manière que dans le pivotement du volet il arrive un moment où les trois articulations se trouvent alignées en donnant ainsi une position de point mort, d'un côté de laquelle le ressort pneumatique actionne le volet en position d'ouverture, tandis que de autre caté il actionne le volet vers la position de fermeture. The air spring relating to a shutter is articulated on the one hand on this shutter and, on the other hand, on the frame of the bay and the articulation on the shutter is placed at a certain distance from the articulation of the shutter itself. even on the frame of the bay, so that in the pivoting of the shutter there comes a moment when the three articulations are aligned, thus giving a neutral position, on one side of which the air spring actuates the shutter in position opening, while on the other hand it activates the shutter towards the closed position.

Il suffit donc à l'utilisateur de commencer à la main le mouvement de fermeture ou d'ouverture du volet pour qu'après le franchissement du point mort ce mouvement se poursuive automatiquement sous l'action du ressort pneumatique, qui maintient finalement le volet dans sa position finale. It is therefore sufficient for the user to manually start the closing or opening movement of the shutter so that, after crossing neutral point, this movement continues automatically under the action of the pneumatic spring, which finally keeps the shutter in place. its final position.

la description qui va suivre en regard des dessins annexés, donnée à titre d'exemple non limitatif, fera bien comprendre comment l'invention peut être réalisée, les particularités décrites ainsi que celles ressortant du dessin faisant partie de l'inventåon.  the description which follows with reference to the appended drawings, given by way of nonlimiting example, will make it clear how the invention can be implemented, the features described as well as those which emerge from the drawing forming part of the invention.

les figures i et 2 sont des vues en élévation et en coupe horizontale de volets de fenêtre de type traditionnel équipés d'un ressort pneumatique selon l'invention. Figures i and 2 are views in elevation and in horizontal section of window shutters of the traditional type fitted with an air spring according to the invention.

La figure 3 est une coupe horizontale à plus grande échelle montrant le détail des articulations de l'un des ressorts pneumatiques. Figure 3 is a horizontal section on a larger scale showing the detail of the joints of one of the air springs.

La figure 4 est la vue en élévation correspondante. Figure 4 is the corresponding elevational view.

Comme on le voit sur les figures i et 2 à chacun des volets 1 d'une fenêtre, qui sont articulés par des gonds 2 sur le bâti de la fen8tre, est associé un ressort pneumatique 3 rempli de gaz sous pression et tendant constamment à l'extension comme on l'a dit dans le préambule de la présente description. Chacun des ressorts 3 est articulé, d'une part, en 4 sur le volet et, d'autre part, en 5 sur le linteau de la baie. As seen in Figures i and 2 to each of the shutters 1 of a window, which are articulated by hinges 2 on the frame of the window, is associated an air spring 3 filled with gas under pressure and constantly tending to l extension as said in the preamble to this description. Each of the springs 3 is articulated, on the one hand, in 4 on the shutter and, on the other hand, in 5 on the lintel of the bay.

L'articulation 4 sur le volet. est prévue sur une ferrure 6 fixée au volet, de manière que cette articulation 4 soit à une certaine distance de la ligne des gonds 2 du volet, ligne autour de laquelle se fait la rotation de celui-ci. Joint 4 on the flap. is provided on a fitting 6 fixed to the flap, so that this articulation 4 is at a certain distance from the line of the hinges 2 of the flap, line around which the rotation of the latter takes place.

On crée ainsi un bras de levier déterminant le moment du couple auquel le volet est soumis par le ressort pneumatique et on le choisira en fonction de la poussée exercée par ce ressort pour obtenir la meilleure action. On peut d'ailleurs remarquer que dans le pivotement du volet, l'articulation 4 décrit l'arc de cercle 7 dont le rayon doit outre compatible avec les possibilités d'extension et le raccourcissement du ressort pneumatique. This creates a lever arm determining the moment of the torque to which the flap is subjected by the pneumatic spring and will be chosen according to the thrust exerted by this spring to obtain the best action. It can moreover be noted that in the pivoting of the flap, the articulation 4 describes the circular arc 7 whose radius must also be compatible with the possibilities of extension and the shortening of the pneumatic spring.

On observe aussi, en examinant la figure 3 que dans le pivotement du volet, il existe- une position intermédiaire représentée en traits interrompus pour laquelle les trois articulations 2, 4 et 5 sont alignées (figure 3) en donnant une position de point mort. We also observe, by examining FIG. 3 that in the pivoting of the flap, there is an intermediate position represented in broken lines for which the three joints 2, 4 and 5 are aligned (FIG. 3) giving a neutral position.

D'un cEté de cette position, la poussée du ressort pneumatique tend à déterminer l'ouverture complète du volet qui est bloqué contre le mur d'une manière permanente à la fin de l'ouverture (position représentée en traits pleins sur la figure 3). Au contraire, de l'autre côté de cette position, la poussée du ressort tend à fermer le volet et à le maintenir fermé (position représentée en traits mixtes à la partie supérieure de la figure 3)'.  On one side of this position, the thrust of the air spring tends to determine the complete opening of the shutter which is locked against the wall permanently at the end of the opening (position shown in solid lines in Figure 3 ). On the contrary, on the other side of this position, the thrust of the spring tends to close the shutter and keep it closed (position shown in phantom in the upper part of FIG. 3) '.

Les manoeuvres d'ouverture et de fermeture des volets sont ainsi simplifiées à ltextrême puisqu'il suffît à l'utilisateur d'amorcer à la main l'ouverture ou la fermeture les ressorts pneumatiques se chargeant de la suite d'une façon automatique. Pour amorcer la manoeuvre des volets, on itinira chacun d'eux d'une poignée 8 placée à l'endroit le plus commode. The maneuvers for opening and closing the shutters are thus simplified in the extreme since it suffices for the user to manually initiate the opening or closing of the pneumatic springs, which are then automatically loaded. To initiate the operation of the shutters, each of them will be routed with a handle 8 placed at the most convenient location.

Qn peut noter que du fait de la teiporisation de l'égalisation des pressions de part et d'autre du piston du ressort pneumatique les mouvements se font sans brusquerie. La temporisation peut d'ailleurs être adaptée aux besoins par le réglage des passages calibrés du piston. Qn can be noted that due to the teiporisation of the equalization of the pressures on both sides of the piston of the pneumatic spring the movements are done without abruptness. The time delay can also be adapted to requirements by adjusting the calibrated passages of the piston.

On remarque aussi que les ressorte pneura- tiques sont disposés à la partie supérieure de la baie, de sorte qu'ils sont peu apparents. We also note that the pneumatic springs are arranged at the upper part of the opening, so that they are not very visible.

On voit sur les figures I et 4 la position inclinée des ressorts pneumatiques entre leurs articulations 4 et 5. Cette inclinaison est utile pour garantir la douceur du mouvement d'ouverture à partir du dépassement du point mort, quand le ressort pneumatique contient une certaine quantité d'huile qui amortit le mouvement du piston à la fin de la course d'extension. L' inclinaieon du ressort pneumatique maintient en effet cette huile pus de la sortie de tige, où elle a pour rSle coiplémentaire de lubrifier le joint d'étanchéité qui est ainsi plus durable. We see in Figures I and 4 the inclined position of the air springs between their joints 4 and 5. This inclination is useful to ensure the smooth opening movement from beyond neutral, when the air spring contains a certain amount of oil which dampens the movement of the piston at the end of the extension stroke. The inclination of the air spring in fact keeps this oil from the rod outlet, where it has the co-complementary role of lubricating the seal, which is thus more durable.

Comme on le voit sur les figures 3 et 4, la tige 3a du piston 3b représentée en pointillés peut être cachée par un tube 3c se déplaçant télescopiquement sur le cylindre 3d du ressort, dans lequel se meut le piston. As seen in Figures 3 and 4, the rod 3a of the piston 3b shown in dotted lines can be hidden by a tube 3c moving telescopically on the cylinder 3d of the spring, in which the piston moves.

Les ressorts pneumatiques peuvent Entre du type blocable dans une position intermédiaire et comporter pour cela une valve, ouvrant ou fermant la coaninication entre les deux faces du piston, ce qui permet d'arr9ter les volets à mi-ouverture si on le désire. The pneumatic springs can be of the lockable type in an intermediate position and for this purpose comprise a valve, opening or closing the co-connection between the two faces of the piston, which makes it possible to stop the flaps at mid-opening if desired.

ils peuvent aussi Entre associés à un contacteur électrique déclenché dans la course d' ouverture des volets pour actionner un dispositif d'alarme.  they can also be associated with an electrical contactor triggered in the opening stroke of the shutters to activate an alarm device.

Il va de soi que les modes de réalisation décrit ne sont que des exemples et l'on pourrait les modifier, notamment par substitution d'équivalents techniques, sans sortir pour cela du cadre de l'invention.  It goes without saying that the embodiments described are only examples and they could be modified, in particular by substitution of technical equivalents, without departing from the scope of the invention.
