Description
DESCRIPTION DESCRIPTION
TITRE : DISPOSITIF DE REGULATION D’UN FLUX D’AIR D’UN VEHICULE AUTOMOBILE TITLE: DEVICE FOR REGULATING AN AIR FLOW OF A MOTOR VEHICLE
[1] L’invention concerne un dispositif de régulation d’un flux d’air circulant au sein d’un échangeur de chaleur pour véhicule automobile et un module de refroidissement muni d’un tel dispositif. Elle est en particulier destinée à l’équipement d’une face avant de véhicule automobile. [1] The invention relates to a device for regulating a flow of air circulating within a heat exchanger for a motor vehicle and a cooling module equipped with such a device. It is intended in particular for equipping the front end of a motor vehicle.
[2] Il est connu d’utiliser des volets pilotés par un actionneur en face avant de véhicule afin de réduire le coefficient de traînée et aussi d’améliorer les performances de refroidissement et de climatisation. Un tel système est le plus souvent désigné par l’acronyme AGS provenant de l’expression de langue anglaise « Active Grille Shutter ». LAGS est de préférence installé au niveau d’une calandre du véhicule automobile. En position d’ouverture de l’entrée d’air, l'air peut circuler à travers la calandre et participer notamment au refroidissement du moteur du véhicule automobile. En position d’obturation de l’entrée d’air, l'air ne pénètre pas via la calandre ce qui réduit la traînée et permet ainsi de réduire la consommation de carburant et l'émission de dioxyde de carbone. LAGS permet donc de réduire la consommation d'énergie et la pollution lorsque le moteur n'a pas besoin d'être refroidi par l'air extérieur. [2] It is known to use flaps controlled by an actuator on the front of the vehicle in order to reduce the drag coefficient and also to improve cooling and air conditioning performance. Such a system is most often referred to by the acronym AGS from the English language expression “Active Grille Shutter”. LAGS is preferably installed at a grille of the motor vehicle. In the open position of the air intake, the air can circulate through the grille and participate in particular in the cooling of the engine of the motor vehicle. In the closed position of the air intake, the air does not enter via the grille which reduces drag and thus helps to reduce fuel consumption and carbon dioxide emissions. LAGS therefore makes it possible to reduce energy consumption and pollution when the motor does not need to be cooled by the outside air.
[3] Dans certains cas, il n’est pas possible de positionner un AGS au niveau de la calandre, devant les échangeurs, à cause d’un environnement inadapté, d’un souhait de client ou autre. [3] In some cases, it is not possible to position an AGS at the level of the grille, in front of the exchangers, due to an unsuitable environment, a customer request or other.
[4] Il est connu des modules de refroidissement pour véhicule automobile comprenant deux échangeurs de chaleur. Un premier échangeur de chaleur a pour fonction de refroidir un circuit annexe du véhicule, tel qu’un dispositif de climatisation ou un dispositif de refroidissement d’air de suralimentation. Un deuxième échangeur de chaleur est nécessaire au refroidissement du moteur du véhicule. Les échangeurs de chaleur sont disposés en face avant du véhicule, assemblés et alignés en série pour être successivement traversés par le flux d’air entrant à travers la calandre du véhicule. Ils comprennent typiquement un faisceau d’échange de chaleur, comprenant des tubes dans lesquels circule le fluide à refroidir et traversé par l’air provenant de la calandre. [4] Motor vehicle cooling modules comprising two heat exchangers are known. A first heat exchanger has the function of cooling an auxiliary circuit of the vehicle, such as an air conditioning device or a charge air cooling device. A second heat exchanger is required to cool the vehicle engine. The heat exchangers are arranged on the front of the vehicle, assembled and aligned in series to be successively crossed by the flow of air entering through the grille of the vehicle. They typically include a heat exchange bundle, comprising tubes in which the fluid to be cooled circulates and through which the air coming from the calender passes.
[5] Afin de dissocier le refroidissement des deux échangeurs de chaleur et optimiser le gain aérodynamique de chaque échangeur de chaleur, le déposant a récemment proposé un dispositif de régulation du flux d’air destiné à circuler dans les échangeurs de chaleur dans une demande de brevet non publiée du déposant. Le dispositif de régulation comprend deux rideaux montés dans un cadre et déplaçables alternativement en translation entre deux positions ouverte et fermée. En se déplaçant entre ces deux positions, les rideaux permettent
au dispositif de régulation de laisser passer ou obturer alternativement le flux d’air traversant la calandre du véhicule automobile. Le déplacement des rideaux s’effectue au moyen d’un système de transmission qui guide le mouvement desdits rideaux en translation, ainsi qu’un actionneur induisant un mouvement au système de transmission. [5] In order to separate the cooling of the two heat exchangers and optimize the aerodynamic gain of each heat exchanger, the applicant recently proposed a device for regulating the flow of air intended to circulate in the heat exchangers in a request for applicant's unpublished patent. The regulating device comprises two curtains mounted in a frame and movable alternately in translation between two open and closed positions. By moving between these two positions, the curtains allow the control device to pass or alternately block the flow of air passing through the grille of the motor vehicle. The movement of the curtains is carried out by means of a transmission system which guides the movement of said curtains in translation, as well as an actuator inducing a movement in the transmission system.
[6] L’invention a pour objet un dispositif de régulation d’un flux d’air destiné à circuler à travers un échangeur de chaleur pour véhicule automobile, le dispositif comprenant au moins un rideau, notamment deux rideaux, aptes(s) à se déplacer selon une direction d’ouverture/fermeture, entre une position fermée obturant le passage du flux d’air et une position ouverte laissant passer le flux d’air, ce dispositif de régulation comportant un système de transmission agencé pour guider le mouvement desdits rideaux, [6] The subject of the invention is a device for regulating a flow of air intended to circulate through a heat exchanger for a motor vehicle, the device comprising at least one curtain, in particular two curtains, capable of move in an opening/closing direction, between a closed position blocking the passage of the air flow and an open position allowing the air flow to pass, this regulation device comprising a transmission system arranged to guide the movement of said drapes,

[34] Selon l’un des aspects de l’invention, un actionneur électrique est prévu pour actionner, à savoir enrouler ou dérouler le ou les rideaux. [34] According to one of the aspects of the invention, an electric actuator is provided to actuate, namely to roll up or unroll the curtain or curtains.
[35] L’invention a encore pour objet, indépendamment ou en combinaison avec ce qui précède, un dispositif de régulation d’un flux d’air destiné à circuler à travers un échangeur de chaleur pour véhicule automobile, le dispositif comprenant deux rideaux aptes à se déplacer selon une direction d’ouverture/fermeture, entre une position fermée obturant le passage du flux d’air et une position ouverte laissant passer le flux d’air, ce dispositif de régulation comportant un système de transmission agencé pour guider le mouvement desdits rideaux, ainsi qu’un actionneur induisant un mouvement au système de transmission, ce système de transmission comportant deux arbres d’enroulement chacun pour l'enroulement et le déroulement de l’un des rideaux, ce système de transmission comportant en outre au moins une courroie actionnable en mouvement et agencée pour faire tourner l’un au moins des arbres d’enroulement à la fois dans le sens d’un enroulement du rideau et dans le sens d’un déroulement du rideau. [35] A further subject of the invention, independently or in combination with the foregoing, is a device for regulating a flow of air intended to circulate through a heat exchanger for a motor vehicle, the device comprising two curtains capable to move in an opening/closing direction, between a closed position blocking the passage of the air flow and an open position allowing the air flow to pass, this regulating device comprising a transmission system arranged to guide the movement said curtains, as well as an actuator inducing a movement in the transmission system, this transmission system comprising two winding shafts each for winding and unwinding one of the curtains, this transmission system further comprising at least a belt operable in movement and arranged to rotate at least one of the winding shafts both in the direction of winding of the curtain and in the direction of unwinding of the ri water.
[36] Selon l’un des aspects de l’invention, l’actionneur est agencé pour faire tourner l’un des arbres d’enroulement sélectivement dans un sens d’enroulement du rideau ou dans un sens de déroulement du rideau. [36] According to one of the aspects of the invention, the actuator is arranged to rotate one of the winding shafts selectively in a rolling direction of the curtain or in a rolling direction of the curtain.
[37] Selon l’un des aspects de l’invention, chaque arbre d’enroulement comporte un pignon denté agencé pour coopérer avec la courroie qui est crantée de sorte que le mouvement de l’un des arbres d’enroulement, notamment un mouvement provoqué par l’actionneur, soit transmis à l’autre arbre d’enroulement. [37] According to one of the aspects of the invention, each winding shaft comprises a toothed pinion arranged to cooperate with the belt which is notched so that the movement of one of the winding shafts, in particular a movement caused by the actuator, or transmitted to the other winding shaft.
[38] Selon l’un des aspects de l’invention, le dispositif de régulation comporte deux courroies chacune à l’une des extrémités des deux arbres d’enroulement de sorte que chaque courroie est associée à deux pignons dentés des deux arbres d’enroulement, ces deux courroies étant agencées pour être en mouvement synchronisé l’une par rapport à l’autre. [38] According to one of the aspects of the invention, the regulating device comprises two belts each at one of the ends of the two winding shafts so that each belt is associated with two toothed pinions of the two shafts of winding, these two belts being arranged to be in synchronized movement with respect to each other.
[39] Selon l’un des aspects de l’invention, le dispositif comporte au moins un organe d’entraînement solidaire d’un bord libre du rideau et agencé pour se déplacer en même temps que la courroie pour accompagner le rideau lors de son enroulement ou de son déroulement de manière à maintenir le rideau à plat.
[40] Selon l’un des aspects de l’invention, l’organe d’entrainement comporte des chariots agencés pour être fixés aux courroies, ou au moins à l’une d’elles, de sorte que l’organe d’entrainement soit solidaire des deux courroies. [39] According to one of the aspects of the invention, the device comprises at least one drive member secured to a free edge of the curtain and arranged to move at the same time as the belt to accompany the curtain during its winding or unwinding so as to keep the curtain flat. [40] According to one of the aspects of the invention, the drive member comprises carriages arranged to be fixed to the belts, or at least to one of them, so that the drive member is attached to the two belts.
[41] Selon l’un des aspects de l’invention, chaque chariot est pincé sur la courroie associée, notamment pincé sur une bande formant la courroie. [41] According to one of the aspects of the invention, each carriage is pinched on the associated belt, in particular pinched on a strip forming the belt.
[42] Selon l’un des aspects de l’invention, pour chaque courroie, le chariot associé à l’un des rideaux est fixé sur un premier brin de la courroie entre les deux arbres d’enroulement et l’autre chariot associé à l’autre des rideaux est fixé sur un deuxième brin de la courroie qui est opposé au premier brin de sorte que les deux chariots puissent être déplacés en directions opposées, soit en s’éloignant l’un de l’autre soit en se rapprochant l’un de l’autre. [42] According to one of the aspects of the invention, for each belt, the carriage associated with one of the curtains is fixed on a first strand of the belt between the two winding shafts and the other carriage associated with the other of the curtains is attached to a second strand of the belt which opposes the first strand so that the two carriages can be moved in opposite directions, either away from each other or toward each other each other.
[43] Selon l’un des aspects de l’invention, l’organe d’entrainement comporte une tige avec à chaque extrémité de la tige l’un des chariots, et la tige étant placée le long d’un bord libre du rideau associé. Notamment lorsque les deux rideaux sont en positon fermée, les deux tiges viennent en appui l’une contre l’autre. Les chariots sont notamment fixés sur la courroie sans possibilité de mouvement relatif par rapport à cette courroie. [43] According to one aspect of the invention, the drive member comprises a rod with at each end of the rod one of the carriages, and the rod being placed along a free edge of the curtain associated. In particular when the two curtains are in the closed position, the two rods come to bear against each other. The carriages are in particular fixed to the belt without the possibility of relative movement with respect to this belt.
[44] Selon l’un des aspects de l’invention, chaque chariot est réalisé en matière plastique. [44] According to one aspect of the invention, each trolley is made of plastic.
[45] Selon l’un des aspects de l’invention, le sens pour enrouler le rideau autour de l’arbre d’enroulement est le même sur les deux arbres. Ceci est permis par le fait que les rideaux s’enroulent de façon opposée sur les deux arbres [45] According to one aspect of the invention, the direction for winding the curtain around the winding shaft is the same on both shafts. This is enabled by the fact that the curtains wrap oppositely on the two shafts
[46] Ainsi la courroie permet la rotation de l’un des arbres d’enroulement simultanément à la mise en mouvement en translation de l’organe d’entrainement du rideau via les chariots. [46] Thus the belt allows the rotation of one of the winding shafts simultaneously with the setting in motion in translation of the drive member of the curtain via the carriages.
[47] L’invention a encore pour objet, indépendamment ou en combinaison avec ce qui précède, un dispositif de régulation d’un flux d’air destiné à circuler à travers un échangeur de chaleur pour véhicule automobile, le dispositif comprenant au moins un rideau, notamment deux rideaux, aptes(s) à se déplacer selon une direction d’ouverture/fermeture, entre une position fermée obturant le passage du flux d’air et une position ouverte laissant passer le flux d’air (F), ce dispositif de régulation comportant un système de transmission agencé pour guider le mouvement desdits rideaux, dans lequel le dispositif comporte un actionneur électrique pour actionner le système de transmission, et un cadre pour loger le ou les rideaux, et dans lequel le cadre comporte une partie avant et une partie arrière, la partie avant étant placée en amont par rapport à la partie arrière suivant le sens du flux d’air, et dans lequel les parties avant et arrière du cadre sont assemblées avec des éléments d’encliquetage.
[48] Selon l’un des aspects de l’invention, les deux parties de boitier sont assemblées de manière étanche, avec notamment interposition d’un joint entre ces parties de boitier. [47] A further subject of the invention, independently or in combination with the foregoing, is a device for regulating a flow of air intended to circulate through a heat exchanger for a motor vehicle, the device comprising at least one curtain, in particular two curtains, capable of moving in an opening/closing direction, between a closed position blocking the passage of the air flow and an open position letting the air flow (F) pass, this regulation device comprising a transmission system arranged to guide the movement of said curtains, in which the device comprises an electric actuator for actuating the transmission system, and a frame for housing the curtain or curtains, and in which the frame comprises a front part and a rear part, the front part being placed upstream with respect to the rear part in the direction of the air flow, and in which the front and rear parts of the frame are assembled with click elements floor. [48] According to one of the aspects of the invention, the two housing parts are assembled in a sealed manner, with in particular the interposition of a seal between these housing parts.
[49] Selon l’un des aspects de l’invention, les parties de boitier forment un logement pour le moteur électrique et l’une au moins des parties de boitier comporte un capot fermant ce logement, ce capot et la partie de boitier étant formés d’un seul tenant. [49] According to one of the aspects of the invention, the housing parts form a housing for the electric motor and at least one of the housing parts comprises a cover closing this housing, this cover and the housing part being formed in one piece.
[50] Selon l’un des aspects de l’invention, l’élément d’encliquetage comporte une patte d’encliquetage déformable agencée pour coopérer avec l’autre élément d’encliquetage. [50] According to one of the aspects of the invention, the latching element comprises a deformable latching tab arranged to cooperate with the other latching element.
[51] Selon l’un des aspects de l’invention, la patte d’encliquetage comporte une ouverture pour coopérer avec l’autre élément d’encliquetage qui comporte un bossage. [51] According to one of the aspects of the invention, the latching tab has an opening to cooperate with the other latching element which has a boss.
[52] Selon l’un des aspects de l’invention, le cadre comporte une pluralité de paires d’éléments d’encliquetage répartis notamment sur les quatre côtés du pourtour de ce cadre. [52] According to one of the aspects of the invention, the frame comprises a plurality of pairs of latching elements distributed in particular on the four sides of the perimeter of this frame.
[53] Selon l’un des aspects de l’invention, le cadre comporte une bordure et le boitier de l’actionneur est placé sur cette bordure. [53] According to one aspect of the invention, the frame has a border and the actuator housing is placed on this border.
[54] Selon l’un des aspects de l’invention, les éléments d’encliquetage présentent des dimensions inférieures aux dimensions de la bordure de sorte que les éléments d’encliquetage restent dans une largeur de cette bordure. [54] According to one of the aspects of the invention, the snap elements have dimensions smaller than the dimensions of the border so that the snap elements remain within a width of this border.
[55] Selon l’un des aspects de l’invention, les éléments d’encliquetage sont formés d’un seul tenant avec les parties de cadre respectives. [55] According to one aspect of the invention, the snap elements are formed integrally with the respective frame parts.
[56] Selon l’un des aspects de l’invention, les parties avant et arrière du cadre sont assemblées sans l’aide de vis ou de boulons. [56] According to one aspect of the invention, the front and rear parts of the frame are assembled without the aid of screws or bolts.
[57] L’invention permet ainsi un assemblage simplifié du cadre. [57] The invention thus allows a simplified assembly of the frame.
[58] L’invention a encore pour objet, indépendamment ou en combinaison avec ce qui précède, un dispositif de régulation d’un flux d’air destiné à circuler à travers un échangeur de chaleur pour véhicule automobile, le dispositif comprenant un ou deux rideaux, apte(s) à se déplacer selon une direction d’ouverture/fermeture, entre une position fermée obturant le passage du flux d’air et une position ouverte laissant passer le flux d’air (F), le ou les rideau(x) étant notamment souple(s), dans lequel le rideau comporte un bord libre solidaire, à l’aide d’un dispositif de fixation, de l’un d’un arbre d’enroulement ou d’un organe d’entrainement, notamment un organe d’entrainement coulissant, dans lequel le dispositif de fixation du rideau comporte deux éléments agencés pour coincer une portion du rideau entre ces deux éléments. [58] A further subject of the invention, independently or in combination with the foregoing, is a device for regulating a flow of air intended to circulate through a heat exchanger for a motor vehicle, the device comprising one or two curtains, able(s) to move in an opening/closing direction, between a closed position blocking the passage of the air flow and an open position allowing the air flow to pass (F), the curtain or curtains ( x) being in particular flexible(s), in which the curtain comprises a free edge secured, using a fixing device, to one of a winding shaft or a drive member, in particular a sliding drive member, in which the device for fixing the curtain comprises two elements arranged to wedge a portion of the curtain between these two elements.
[59] Grâce à l’invention, la fixation du rideau sur l’arbre enrouleur et/ou l’organe d’entrainement s’en trouve simplifiée. Il n’est pas nécessaire notamment d’avoir un élément
supplémentaire, par exemple un jonc, distinct de l’arbre enrouleur ou de l’organe d’entrainement. Le rideau peut être pris sur l’arbre enrouleur ou l’organe d’entrainement en même temps que cet arbre ou cet organe sont assemblés. [59] Thanks to the invention, fixing the curtain on the winding shaft and/or the drive member is simplified. In particular, it is not necessary to have an element additional, for example a ring, separate from the winding shaft or the drive member. The curtain can be taken on the winding shaft or the drive member at the same time as this shaft or this member are assembled.
[60] Selon l’un des aspects de l’invention, les deux éléments du dispositif de fixation font partie de l’arbre d’enroulement ou de l’organe d’entrainement sur lequel est fixé le bord libre du rideau. [60] According to one aspect of the invention, the two elements of the fixing device are part of the winding shaft or the drive member on which the free edge of the curtain is fixed.
[61] Selon l’un des aspects de l’invention, le bord libre du rideau qui est fixé sur le dispositif de fixation est rectiligne et les éléments entre lesquels est coincée la portion de rideau s’étendent parallèlement à ce bord libre rectiligne. [61] According to one aspect of the invention, the free edge of the curtain which is fixed to the fixing device is straight and the elements between which the curtain portion is wedged extend parallel to this straight free edge.
[62] Selon l’un des aspects de l’invention, les éléments de fixation présentent des faces de coincement entre lesquelles est coincée la portion de rideau. [62] According to one of the aspects of the invention, the fixing elements have wedging faces between which the curtain portion is wedged.
[63] Selon l’un des aspects de l’invention, les faces de coincement présentent des formes complémentaires entre lesquelles est placée la portion de rideau à coincer. [63] According to one of the aspects of the invention, the wedging faces have complementary shapes between which the portion of curtain to be wedged is placed.
[64] Selon l’un des aspects de l’invention, les faces de coincement présentent des formes sensiblement arrondies de sorte que la portion de rideau coincée s’enroule autour de l’une de ces faces d’enroulement, sur un tour complet ou sur un secteur angulaire seulement du tour. [64] According to one of the aspects of the invention, the wedging faces have substantially rounded shapes so that the stuck portion of the curtain wraps around one of these winding faces, over a complete turn. or on an angular sector only of the lathe.
[65] Selon l’un des aspects de l’invention, les deux éléments définissent entre eux une fente d’entrée pour la portion de rideau, et le rideau est notamment coincé entre les deux éléments depuis la fente d’entrée jusqu’au bord libre du rideau, formant la portion coincée du rideau. [65] According to one of the aspects of the invention, the two elements define between them an entrance slot for the curtain portion, and the curtain is in particular wedged between the two elements from the entrance slot to the free edge of the curtain, forming the wedged portion of the curtain.
[66] Selon l’un des aspects de l’invention, les éléments du dispositif de fixation sont assemblés ensemble par encliquetage. [66] According to one aspect of the invention, the elements of the fastening device are assembled together by snap-fastening.
[67] Notamment l’un des éléments comporte un resserrement qui est franchi par Tautre élément au moment de l’assemblage, et ce resserrement se remet en place et emprisonne l’élément complémentaire. [67] In particular, one of the elements has a constriction which is crossed by the other element at the time of assembly, and this constriction is put back in place and traps the complementary element.
[68] Selon l’un des aspects de l’invention, l’un des éléments du dispositif de fixation comporte un tube creux sur lequel est formé l’une des faces de coincement. [68] According to one aspect of the invention, one of the elements of the fixing device comprises a hollow tube on which is formed one of the wedging faces.
[69] Ce tube creux est notamment logé dans un logement cylindrique de l’autre élément du dispositif de fixation, ce logement présentant notamment un resserrement pour emprisonner le tube creux. [69] This hollow tube is in particular housed in a cylindrical housing of the other element of the fixing device, this housing having in particular a constriction to imprison the hollow tube.
[70] Dans ce cas, le tube creux est agencé pour franchir le resserrement du cylindre grâce à une déformation de l’élément correspondant, notamment par écartement de deux lèvres qui forment les deux rebords de ce resserrement. Puis une fois que le tube creux a franchi le
resserrement, les deux lèvres se rapprochent par déformation élastique pour emprisonner le tube creux. Il s’agit d’un assemblage par encliquetage. [70] In this case, the hollow tube is arranged to cross the constriction of the cylinder thanks to a deformation of the corresponding element, in particular by separating two lips which form the two edges of this constriction. Then once the hollow tube has crossed the tightening, the two lips come together by elastic deformation to trap the hollow tube. This is a snap fit assembly.
[71] Dans une variante, le tube creux est inséré dans ce logement par une ouverture latérale puis est glissé dans ce logement par un mouvement de translation suivant l’axe de ce cylindre. [71] Alternatively, the hollow tube is inserted into this housing through a side opening and is then slid into this housing by a translational movement along the axis of this cylinder.
[72] Dans cet exemple, la portion de rideau ne recouvre pas une face extérieure des éléments du dispositif de fixation. [72] In this example, the curtain portion does not cover an outer face of the elements of the fastening device.
[73] Dans cet exemple, le rideau ne s’enroule pas autour des éléments du dispositif de fixation, qui est notamment coulissant en translation, et non rotatif. Ce dispositif de fixation fait notamment partie de l’organe d’entrainement du rideau. [73] In this example, the curtain does not wrap around the elements of the fixing device, which is in particular sliding in translation, and not rotating. This fixing device is in particular part of the drive member of the curtain.
[74] Selon l’un des aspects de l’invention, les éléments de fixation comportent chacun une face extérieure sur lesquelles s’appuie le rideau, pour permettre au rideau de s’enrouler autour de ces deux faces extérieures. [74] According to one of the aspects of the invention, the fixing elements each have an outer face on which the curtain rests, to allow the curtain to wrap around these two outer faces.
[75] Dans cet exemple, le dispositif de fixation du rideau fait partie de l’arbre d’enroulement. [75] In this example, the curtain attachment device is part of the winding shaft.
[76] L’un des éléments du dispositif de fixation comporte un tube creux et, de part et d’autre de ce tube creux, deux extensions, et la face de coincement est formée sur ce tube creux et les extensions. [76] One of the elements of the fixation device comprises a hollow tube and, on either side of this hollow tube, two extensions, and the wedging face is formed on this hollow tube and the extensions.
[77] Ces extensions sont creuses notamment. [77] These extensions are notably hollow.
[78] La portion de rideau coincée s’étend notamment sur le tube creux et les extensions. [78] The stuck portion of the curtain extends in particular over the hollow tube and the extensions.
[79] Selon l’un des aspects de l’invention, à la place du ou des tubes creux mentionnés ci- dessus, il est possible d’avoir un tube plein. [79] According to one of the aspects of the invention, instead of the hollow tube or tubes mentioned above, it is possible to have a solid tube.
[80] Selon l’un des aspects de l’invention, les éléments du dispositif de fixation sont réalisés en matière plastique, notamment par moulage ou extrusion. [80] According to one of the aspects of the invention, the elements of the fixing device are made of plastic, in particular by molding or extrusion.
[81] Selon l’un des aspects de l’invention, ces éléments présentent notamment une forme de profilé. [81] According to one of the aspects of the invention, these elements have in particular a profile shape.

[96] .La figure 1 illustre un dispositif de régulation 10 d’un flux d’air F ainsi qu’un module de refroidissement 1 conformes à l’invention, selon une vue de côté. Le module de refroidissement 1 s’étend en profondeur selon une direction X destinée à correspondre à l’axe longitudinal du véhicule équipé. Le flux d’air F s’écoule sensiblement parallèlement à la direction X. Le module est configuré pour être fixé sur un support, tel qu’un châssis du véhicule. [96]. Figure 1 illustrates a device 10 for regulating an air flow F as well as a cooling module 1 in accordance with the invention, in a side view. The cooling module 1 extends in depth along a direction X intended to correspond to the longitudinal axis of the equipped vehicle. The air flow F flows substantially parallel to the direction X. The module is configured to be fixed on a support, such as a vehicle chassis.
[97] Le module de refroidissement 1 comprend un échangeur de chaleur amont 2 (situé à gauche sur la fig. 1) et un échangeur de chaleur aval 3 (situé à droite sur la fig. 1) agencés en série selon le sens d’écoulement du flux d’air F les traversant. Autrement dit, le module de
refroidissement 1 est configuré pour être disposé sur son support, de sorte que l’échangeur de chaleur amont 2 soit traversé par le flux d’air F en premier et l’échangeur de chaleur aval 3 en deuxième. [97] The cooling module 1 comprises an upstream heat exchanger 2 (located on the left in fig. 1) and a downstream heat exchanger 3 (located on the right in fig. 1) arranged in series according to the direction of flow of the air flow F passing through them. In other words, the modulus of cooler 1 is configured to be arranged on its support, so that the upstream heat exchanger 2 is crossed by the air flow F first and the downstream heat exchanger 3 second.
[98] L’échangeur de chaleur amont 2 est un radiateur de refroidissement, dit basse température, servant à refroidir un liquide de refroidissement d’une boucle d’échange de chaleur, dite basse température, comprenant, notamment, un condenseur de climatisation et/ou un refroidisseur d’air de suralimentation. L’échangeur de chaleur aval 3 est, par exemple, un radiateur de refroidissement haute température destiné à refroidir un liquide de refroidissement d’une boucle d’échange de chaleur comprenant un moteur du véhicule. L’air qui traverse cet échangeur aval 3 refroidit le liquide de refroidissement du moteur. [98] The upstream heat exchanger 2 is a so-called low temperature cooling radiator, used to cool a coolant of a so-called low temperature heat exchange loop, comprising, in particular, an air conditioning condenser and /or a charge air cooler. The downstream heat exchanger 3 is, for example, a high temperature cooling radiator intended to cool a coolant of a heat exchange loop comprising an engine of the vehicle. The air passing through this downstream exchanger 3 cools the engine coolant.
[99] Chaque échangeur 2, 3 comprend, par exemple, un faisceau d’échange de chaleur et des chambres de collecte disposées latéralement de part et d’autre du faisceau (non illustré). Le faisceau est traversé par le flux d’air F. Il comprend un ensemble de tubes parallèles les uns aux autres, débouchant dans les chambres de collecte, pour la circulation du liquide de refroidissement (non illustré). [99] Each exchanger 2, 3 comprises, for example, a heat exchange beam and collection chambers arranged laterally on either side of the beam (not shown). The bundle is crossed by the air flow F. It includes a set of tubes parallel to each other, opening into the collection chambers, for the circulation of the coolant (not shown).
[100] Le module de refroidissement 1 est avantageusement configuré pour autoriser un écoulement d’air de manière sensiblement étanche entre lesdits échangeurs de chaleur 2, 3, c’est-à-dire que l’échangeur de chaleur amont 2 et l’échangeur de chaleur aval 3 sont assemblés l’un à autre de sorte que l’échangeur de chaleur aval 3 ne soit pas directement traversé par de l’air venant de l’extérieur du module. Autrement dit, le flux d’air F traversant l’échangeur de chaleur aval 3 est issu du flux d’air traversant l’échangeur de chaleur amont 2. Pour cela, le module de refroidissement 1 peut, par exemple, comprendre des moyens d’étanchéité permettant de guider l’intégralité du flux d’air ayant traversé l’échangeur de chaleur amont 2 vers l’échangeur de chaleur aval 3 sans perte de débit d’air. Ces moyens d’étanchéité, non illustrés, peuvent par exemple comprendre une gaine agencée entre les deux échangeurs de chaleur 2,3. [100] The cooling module 1 is advantageously configured to allow a flow of air in a substantially sealed manner between said heat exchangers 2, 3, that is to say that the upstream heat exchanger 2 and the heat exchanger downstream heat exchanger 3 are assembled together so that the downstream heat exchanger 3 is not directly traversed by air coming from outside the module. In other words, the air flow F passing through the downstream heat exchanger 3 comes from the air flow passing through the upstream heat exchanger 2. For this, the cooling module 1 can, for example, comprise means of tightness to guide the entire flow of air having passed through the upstream heat exchanger 2 to the downstream heat exchanger 3 without loss of air flow. These sealing means, not shown, can for example comprise a sheath arranged between the two heat exchangers 2,3.
[101] Pour faciliter le passage du flux d’air dans le module de refroidissement 1 , notamment lorsque le véhicule est à l’arrêt, le module comprend avantageusement un groupe moto- ventilateur 10 apte à faire circuler l’air dans le module de refroidissement 1. Comme illustré sur la figure 1 , le groupe moto-ventilateur 4 est ici disposé en aval de l’échangeur de chaleur aval 3, le groupe moto-ventilateur 4 étant configuré pour aspirer l’air depuis une entrée d’air du véhicule, qui est de préférence définie par sa calandre. [101] To facilitate the passage of the air flow in the cooling module 1, in particular when the vehicle is stationary, the module advantageously comprises a motor-fan unit 10 able to circulate the air in the cooling module. cooling 1. As illustrated in Figure 1, the motor-fan unit 4 is here arranged downstream of the downstream heat exchanger 3, the motor-fan unit 4 being configured to suck air from an air inlet of the vehicle, which is preferably defined by its grille.
[102] Le module de refroidissement 1 selon l’invention comprend, en outre, un dispositif de régulation 10 du flux d’air agencé préférentiellement entre l’échangeur de chaleur amont 2 et l’échangeur de chaleur aval 3. Le dispositif de régulation 10 présente une faible épaisseur
dans la profondeur du module de refroidissement. Le dispositif de régulation 10 contrôle le passage du flux d’air F de l’échangeur de chaleur amont 2 vers l’échangeur de chaleur aval 3 par l’intermédiaire de stores ou rideaux 11 enroulables/déroulables. [102] The cooling module 1 according to the invention further comprises a device 10 for regulating the flow of air preferably arranged between the upstream heat exchanger 2 and the downstream heat exchanger 3. The regulating device 10 has a low thickness in the depth of the cooling module. The regulating device 10 controls the passage of the air flow F from the upstream heat exchanger 2 to the downstream heat exchanger 3 by means of blinds or curtains 11 that can be rolled up/unrolled.
[103] En variante, le module de refroidissement 1 selon l’invention peut comprendre un unique échangeur de chaleur, par exemple un radiateur de refroidissement, ledit dispositif de régulation 10 étant alors agencé en amont ou en aval dudit échangeur de chaleur. Dans une telle configuration, le flux d’air F traversant l’échangeur de chaleur est issu du flux d’air F traversant le dispositif de régulation ou débouche sur ledit dispositif de régulation. [103] As a variant, the cooling module 1 according to the invention may comprise a single heat exchanger, for example a cooling radiator, said regulating device 10 then being arranged upstream or downstream of said heat exchanger. In such a configuration, the air flow F passing through the heat exchanger comes from the air flow F passing through the regulating device or leads to said regulating device.
[104] En référence aux figures 2 et 3, le dispositif de régulation 10 selon un premier mode de réalisation de l’invention est illustré en vue schématique de face. Le dispositif comprend deux rideaux 11 de forme généralement rectangulaire. Chaque rideau 11 est délimité par une bordure proximale 11a, deux bordures latérales 11b, et une bordure distale 11c. Lesdites bordures latérales 11b sont opposées et sensiblement parallèles à une direction Z, orthogonale à la direction X, tandis que ladite bordure proximale 11a et ladite bordure distale 11c sont opposées et sensiblement parallèles à une direction Y, orthogonale aux directions X et Z, la direction Z représentant ici la verticale. [104] Referring to Figures 2 and 3, the control device 10 according to a first embodiment of the invention is illustrated in schematic front view. The device comprises two curtains 11 of generally rectangular shape. Each curtain 11 is delimited by a proximal border 11a, two lateral borders 11b, and a distal border 11c. Said lateral borders 11b are opposite and substantially parallel to a Z direction, orthogonal to the X direction, while said proximal border 11a and said distal border 11c are opposite and substantially parallel to a Y direction, orthogonal to the X and Z directions, the direction Z here representing the vertical.
[105] À la figure 2, le dispositif de régulation 10 est en position ouverte PO, c’est-à-dire que les rideaux 11 laissent passer le flux d’air F. Dans cette configuration, les bordures proximales 11a desdits rideaux 11 sont à distance l’une de l’autre. Plus précisément, une première bordure proximale 11a se situe à proximité d’un montant supérieur d’un cadre 50 du dispositif de régulation, notamment au niveau d’une première position ouverte PO1 , tandis qu’une deuxième bordure proximale 11a se situe à proximité d’un montant inférieur du cadre 50, notamment au niveau d’une deuxième position ouverte PO2, opposée à PO1 par rapport à un axe passant par une ligne en pointillés PF - PF. [105] In Figure 2, the control device 10 is in the open position PO, that is to say that the curtains 11 allow the flow of air F to pass. In this configuration, the proximal edges 11a of said curtains 11 are distant from each other. More specifically, a first proximal edge 11a is located near an upper upright of a frame 50 of the regulation device, in particular at a first open position PO1, while a second proximal edge 11a is located near of a lower upright of the frame 50, in particular at the level of a second open position PO2, opposite to PO1 with respect to an axis passing through a dotted line PF - PF.
[106] Le dispositif de régulation 10 comprend en outre des arbres 53 d’enroulement/déroulement des rideaux, reliés au cadre 50 par des paliers d’articulation 52. [106] The regulating device 10 further comprises shafts 53 for winding/unwinding the curtains, connected to the frame 50 by hinge bearings 52.
[107] Préférentiellement, chaque rideau 11 est maintenu tendu par un moyen de mise en tension 54 relié à sa bordure distale 11c. Les moyens de mise en tension 54 exercent une force sur les rideaux 11 , de sorte que lesdits rideaux soient continuellement maintenus tendus. Par exemple, les moyens de mise en tension 54 peuvent être des ressorts, notamment des ressorts spirales, ou tout autre moyen permettant de maintenir lesdits rideaux 11 tendus. Préférentiellement, chaque moyen de mise en tension 54 est lié d’une part au cadre 50 et d’autre part, à l’arbre d’enroulement/ déroulement 53.
[108] À la figure 3, le dispositif de régulation 10 est en position fermée PF. Les rideaux 11 s’étendent dans un plan, dit plan d’extension des rideaux en position fermée. Ledit plan d’extension des rideaux en position fermée est orienté selon la direction Z, correspondant à la direction d’ouverture/fermeture des rideaux, et selon la direction Y. Autrement dit, ledit plan d’extension des rideaux en position fermée s’étend de manière transversale au flux d’air F. Dans cette configuration, les bordures proximales 11a respectives des rideaux 11 sont en contact l’une de l’autre au niveau de la ligne en pointillés PF - PF. Les rideaux 11 obturent donc le passage du flux d’air F qui circule perpendiculairement au plan d’extension des rideaux en position fermée. [107] Preferably, each curtain 11 is held taut by tensioning means 54 connected to its distal edge 11c. The tensioning means 54 exert a force on the curtains 11, so that said curtains are continuously kept taut. For example, the tensioning means 54 can be springs, in particular spiral springs, or any other means making it possible to keep said curtains 11 taut. Preferably, each tensioning means 54 is linked on the one hand to the frame 50 and on the other hand to the winding/unwinding shaft 53. [108] In Figure 3, the control device 10 is in the closed position PF. The curtains 11 extend in a plane, called the curtain extension plane in the closed position. Said extension plane of the curtains in the closed position is oriented in the Z direction, corresponding to the opening/closing direction of the curtains, and in the Y direction. In other words, said extension plane of the curtains in the closed position is extends transversely to the airflow F. In this configuration, the respective proximal edges 11a of the curtains 11 are in contact with each other at the dotted line PF - PF. The curtains 11 therefore block the passage of the air flow F which circulates perpendicular to the plane of extension of the curtains in the closed position.
[109] Le dispositif de régulation 10 est configuré de sorte que lesdits rideaux 11 sont aptes à se déplacer selon la direction d’ouverture/fermeture Z, dans ledit plan d’extension des rideaux en position fermée. En d’autres termes, le dispositif peut adopter, alternativement les configurations illustrées aux figures 2 et 3. À cet effet, le dispositif de régulation 10 comprend un système de transmission 20 et au moins deux organes d’entraînement 30 reliés audit système de transmission 20. [109] The regulating device 10 is configured so that said curtains 11 are capable of moving in the opening/closing direction Z, in said curtain extension plane in the closed position. In other words, the device can alternatively adopt the configurations illustrated in FIGS. 2 and 3. To this end, the regulation device 10 comprises a transmission system 20 and at least two drive members 30 connected to said transmission system 20.
[110] Les caractéristiques et le principe de fonctionnement du système de transmission 20 sont décrits ci-dessous. [110] The characteristics and principle of operation of the transmission system 20 are described below.
[111] Le système de transmission 20 comprend des pignons 21. Comme cela peut être mieux vu à la figure 1 , lesdits pignons 21 comprennent une bordure périphérique 21a et une denture 21b située sur ladite bordure périphérique 21a. Les pignons 21 sont aptes à pivoter, dans le sens horaire ou, inversement, dans le sens anti-horaire, autour d’un axe de rotation orienté selon la direction Y. [111] The transmission system 20 comprises sprockets 21. As can best be seen in Figure 1, said sprockets 21 comprise a peripheral edge 21a and a toothing 21b located on said peripheral edge 21a. The pinions 21 are capable of pivoting, clockwise or, conversely, counter-clockwise, around an axis of rotation oriented in the direction Y.
[112] À cet effet, le dispositif de régulation 10 comprend, de préférence, au moins un actionneur 40 configuré pour entraîner ledit système de transmission 20. L’actionneur comprend un arbre moteur 41 , mobile en rotation autour de l’axe de rotation desdits pignons 21. L’actionneur 40 comprend en outre un vérin hydraulique ou pneumatique ou plus généralement tout organe moteur permettant d’induire un mouvement de rotation de l’arbre moteur 41. L’arbre moteur 41 est en liaison avec les pignons 21. Préférentiellement, l’organe moteur de l’actionneur 40 se situe en dehors du cadre 50. [112] To this end, the control device 10 preferably comprises at least one actuator 40 configured to drive said transmission system 20. The actuator comprises a motor shaft 41, rotatable around the axis of rotation of said pinions 21. The actuator 40 further comprises a hydraulic or pneumatic cylinder or more generally any motor member making it possible to induce a rotational movement of the motor shaft 41. The motor shaft 41 is in connection with the pinions 21. Preferably, the motor member of the actuator 40 is located outside the frame 50.
[113] Préférentiellement, ledit arbre moteur 41 est une tige cylindrique s’étendant entre deux montants latéraux du cadre 50, et suivant la ligne en pointillés PF - PF. De préférence, une bordure intérieure des pignons 21 se conforme avec l’arbre moteur 41 , c’est-à-dire que ladite bordure intérieure épouse le contour de l’arbre moteur 41 , de sorte que lesdits pignons 21 puissent être guidés en rotation par l’arbre moteur 41. L’arbre moteur 41 est articulé sur des paliers 44, liés au cadre 50.
[114] Le système de transmission 20 comprend en outre des tiges dentées 22 sensiblement parallèles à la direction Z. Comme cela peut être mieux vu sur la figure 1, chaque tige dentée 22 présente une denture 22a et une bordure plane 22b. Lesdites tiges dentées 22 sont engrenées deux à deux sur lesdits pignons 21 par l’intermédiaire de leurs dentures respective 22a. Autrement dit, la denture 22a des tiges dentées 22 se conforme précisément à la denture 21b des pignons 21. Les tiges dentées 22 sont situées de part et d’autre des pignons 21 selon la direction X. Ainsi, sur la figure 2, des premières tiges dentées 22, dont la denture 22a apparaît à une position Pt2, sont reliées à un premier rideau 11 situé en-dessous de la ligne en pointillés PF - PF, tandis que des deuxièmes tiges dentées 22, dont la bordure plane 22b apparaît à une position Pt1 , sont reliées à un deuxième rideau 11 situé au-dessus de la ligne en pointillés PF - PF. [113] Preferably, said motor shaft 41 is a cylindrical rod extending between two side uprights of the frame 50, and along the dotted line PF - PF. Preferably, an inner edge of the pinions 21 conforms with the motor shaft 41, that is to say that said inner edge matches the contour of the motor shaft 41, so that said pinions 21 can be guided in rotation. by the motor shaft 41. The motor shaft 41 is articulated on bearings 44, linked to the frame 50. [114] The transmission system 20 further comprises toothed rods 22 substantially parallel to the Z direction. As can best be seen in Figure 1, each toothed rod 22 has a toothing 22a and a flat edge 22b. Said toothed rods 22 are meshed two by two on said pinions 21 via their respective teeth 22a. In other words, the toothing 22a of the toothed rods 22 conforms precisely to the toothing 21b of the pinions 21. The toothed rods 22 are located on either side of the pinions 21 in the direction X. Thus, in FIG. 2, first toothed rods 22, whose toothing 22a appears at a position Pt2, are connected to a first curtain 11 located below the dotted line PF - PF, while second toothed rods 22, whose flat edge 22b appears at a position Pt1, are connected to a second curtain 11 located above the dotted line PF - PF.
[115] Lorsque les pignons 21 tournent, les tiges dentées 22 dont les dentures 22a apparaissent à la position Pt2 coulissent en direction du montant supérieur du cadre 50, c’est- à-dire vers la position Pt1 , tandis que simultanément les tiges dentées 22 dont les bordures planes 22b apparaissent à la position Pt 1 coulissent en direction du montant inférieur du cadre 50, c’est-à-dire la position Pt2. Les tiges dentées 22 associées à un même pignon sont donc aptes à effectuer des mouvements de translation symétriquement opposés dans la direction Z. [115] When the sprockets 21 rotate, the toothed rods 22 whose teeth 22a appear at the Pt2 position slide towards the upper upright of the frame 50, that is to say towards the Pt1 position, while simultaneously the toothed rods 22 whose planar edges 22b appear at position Pt 1 slide in the direction of the lower upright of frame 50, that is to say position Pt2. The toothed rods 22 associated with the same pinion are therefore able to perform symmetrically opposed translational movements in the Z direction.
[116] Avantageusement, les pignons 21 et une paire de tiges dentées 22 correspondantes sont situés symétriquement de chaque côté desdits rideaux 11. Dans cette configuration, lorsque l’actionneur 40 est en fonctionnement, le système de transmission 20 est capable d’entraîner les organes d’entraînement 30, auquel il est relié, en maintenant l’horizontalité desdits organes d’entraînement par rapport à la direction Y. [116] Advantageously, the pinions 21 and a pair of corresponding toothed rods 22 are located symmetrically on each side of said curtains 11. In this configuration, when the actuator 40 is in operation, the transmission system 20 is capable of driving the drive members 30, to which it is connected, maintaining the horizontality of said drive members with respect to the Y direction.
[117] Comme mentionné précédemment, le dispositif de régulation 10 comprend en outre au moins deux organes d’entraînement 30. Leurs caractéristiques et leur fonctionnement sont décrits ci-dessous. [117] As mentioned previously, the regulating device 10 further comprises at least two drive members 30. Their characteristics and their operation are described below.
[118] De façon générale, lesdits organes d’entraînement 30 sont reliés au système de transmission 20. Plus précisément, ici, chaque organe d’entraînement 30 est relié à l’une desdites tiges dentées 22, de sorte que tout coulissement desdites tiges dentées 22 selon la direction Z entraîne un mouvement de translation desdits organes d’entraînement 30 selon la même direction. [118] In general, said drive members 30 are connected to the transmission system 20. More specifically, here, each drive member 30 is connected to one of said toothed rods 22, so that any sliding of said rods toothed 22 in the direction Z causes a translational movement of said drive members 30 in the same direction.
[119] Dans une telle configuration, le système de transmission 20 étant « denté », par l’intermédiaire du pignon et des tiges dentées correspondantes, il permet de limiter le glissement lorsque l’actionneur 40 est en fonctionnement. Le système de transmission 20 permet donc de maintenir constante la vitesse avec laquelle sont entraînés les organes
d’entraînement. Cela permet, en outre, de transmettre efficacement les efforts. Par exemple, une tige dentée 22 dont la denture 22a se déplace depuis la position PT 1 vers la position PT2 induit un déplacement équivalent de l’organe d’entraînement 30 auquel elle est reliée depuis une position distale, proche de l’arbre d’enroulement/déroulement 53, vers une position proximale, proche de l’arbre moteur 41. [119] In such a configuration, the transmission system 20 being "toothed", via the pinion and the corresponding toothed rods, it makes it possible to limit slippage when the actuator 40 is in operation. The transmission system 20 therefore makes it possible to maintain constant the speed with which the components are driven. training. This also makes it possible to effectively transmit the forces. For example, a toothed rod 22 whose toothing 22a moves from the position PT 1 to the position PT2 induces an equivalent movement of the drive member 30 to which it is connected from a distal position, close to the drive shaft. winding/unwinding 53, towards a proximal position, close to the motor shaft 41.
[120] Préférentiellement, les organes d’entraînement 30 sont des barres d’entraînement rigides. Lesdites barres d’entraînement 30 relient entre elles, deux à deux, lesdites tiges dentées 22 et sont aptes à être guidées en translation par lesdites tiges dentées 22. Lesdites barres d’entraînement 30 sont liées directement auxdits rideaux 11 , de sorte que tout mouvement de translation de ladite barre d’entraînement selon la direction Z induise un mouvement de translation dudit rideau 11 selon la même direction. Lesdites barres d’entraînement 30 peuvent être liées de façon rigide aux rideaux 11. Alternativement, lesdites barres d’entraînement 30 peuvent être liées façon souple aux rideaux 11. En outre, les organes d’entraînement 30 étant maintenus horizontaux par la présence d’un pignon 21 et des tiges 22 correspondantes de chaque côté des rideaux 11 , les bordures 11a sont en conséquence maintenues horizontales. Cela permet également de répartir symétriquement les efforts au niveau des organes d’entraînement 30. [120] Preferably, the drive members 30 are rigid drive bars. Said drive bars 30 connect together, two by two, said toothed rods 22 and are able to be guided in translation by said toothed rods 22. Said drive bars 30 are linked directly to said curtains 11, so that any movement translation of said drive bar in direction Z induces a translational movement of said curtain 11 in the same direction. Said drive bars 30 can be linked rigidly to the curtains 11. Alternatively, said drive bars 30 can be linked flexibly to the curtains 11. In addition, the drive members 30 being kept horizontal by the presence of a gable 21 and corresponding rods 22 on each side of the curtains 11, the edges 11a are therefore kept horizontal. This also makes it possible to distribute the forces symmetrically at the level of the drive members 30.
[121] Comme cela peut être mieux vu dans l’exemple illustré à la figure 1 , la tige dentée 22 se trouvant en partie supérieure (à gauche sur le dessin) est rectiligne et la barre d’entraînement 30 associée est accrochée à une extrémité supérieure de ladite tige dentée 22. La tige dentée 22 se trouvant en partie inférieure (à droite sur le dessin) présente une configuration en L, la grande branche du L présentant la denture et la petite branche se terminant dans le prolongement de l’autre tige dentée 22. La barre d’entraînement 30 associée à la tige dentée 22 en L est située à l’extrémité libre de ladite petite branche du L, de sorte que les deux rideaux 11 soient sensiblement dans le même plan. [121] As can be better seen in the example illustrated in Figure 1, the toothed rod 22 located in the upper part (on the left in the drawing) is straight and the associated drive bar 30 is hooked at one end top of said toothed rod 22. The toothed rod 22 located in the lower part (on the right in the drawing) has an L configuration, the large branch of the L having the teeth and the small branch ending in the extension of the other toothed rod 22. The drive bar 30 associated with the L-shaped toothed rod 22 is located at the free end of said small branch of the L, so that the two curtains 11 are substantially in the same plane.
[122] En variante, lesdits organes d’entraînement 30 peuvent être des pions reliés de façon fixe d’une part au système de transmission 20 et d’autre part aux rideaux 11. Les pions sont prévus de part et d’autre de chacun des rideaux 11 , chaque coin proximal des rideaux étant alors fixé auxdits pions. [122] As a variant, said drive members 30 may be pegs fixedly connected on the one hand to the transmission system 20 and on the other hand to the curtains 11. The pegs are provided on either side of each curtains 11, each proximal corner of the curtains then being fixed to said pins.
[123] Le principe de fermeture des rideaux 11 est le suivant. [123] The principle of closing the curtains 11 is as follows.
[124] Lorsque l’actionneur 40 est activé, les pignons 21 effectuent un mouvement de rotation autour de son axe de rotation. Ce mouvement de rotation des pignons 21 induit un mouvement de translation des tiges dentées 22 qui leurs sont respectivement associées selon la direction Z. Comme illustré à la figure 3, lesdites tiges dentées 22 dont les dentures 22a sont initialement situées à une position Pt2 se déplacent depuis la position Pt2 vers la position Pt1 , et,
inversement les tiges dentées 22 dont les bordures planes 22b sont initialement situées à la position Pt1 se déplacent depuis ladite position Pt1 vers la position Pt2. [124] When the actuator 40 is activated, the pinions 21 perform a rotational movement around its axis of rotation. This rotational movement of the pinions 21 induces a translational movement of the toothed rods 22 which are respectively associated with them in the direction Z. As illustrated in FIG. 3, said toothed rods 22 whose teeth 22a are initially located at a position Pt2 from position Pt2 to position Pt1 , and, conversely the toothed rods 22 whose planar edges 22b are initially located at position Pt1 move from said position Pt1 to position Pt2.
[125] Incidemment, les organes d’entraînement 30 reliés auxdites tiges dentées 22 sont simultanément guidés en translation dans des sens opposés et entraînent les rideaux 11 dans leur mouvement. En se déplaçant, les organes d’entraînement 30 guident lesdits rideaux 11 , de sorte que leurs bordures proximales 11a, initialement situées aux positions PO1 et PO2, atteignent la position fermée PF et se trouvent en contact l’une de l’autre. [125] Incidentally, the drive members 30 connected to said toothed rods 22 are simultaneously guided in translation in opposite directions and drive the curtains 11 in their movement. As they move, drive members 30 guide said curtains 11 so that their proximal edges 11a, initially located at positions PO1 and PO2, reach the closed position PF and are in contact with one another.
[126] Les deux pignons 21 étant simultanément entraînés par l’arbre moteur 41 , les rideaux 11 sont guidés de manière symétrique l’un par rapport à l’autre lors de leur déplacement. La distance séparant les deux rideaux 11 , notamment leurs bordures proximales 11a, reste égale de part et d’autre de la ligne en pointillés PF - PF tout au long de leur déplacement. Lorsque les rideaux 11 sont en contact, ils ne laissent pas passer le flux d’air F circulant perpendiculairement au plan d’extension des rideaux en position fermée. [126] The two pinions 21 being simultaneously driven by the motor shaft 41, the curtains 11 are guided symmetrically relative to each other during their movement. The distance separating the two curtains 11, in particular their proximal edges 11a, remains equal on either side of the dotted line PF - PF throughout their displacement. When the curtains 11 are in contact, they do not allow the flow of air F to pass, circulating perpendicular to the plane of extension of the curtains in the closed position.
[127] Inversement, les rideaux 11 sont aptes à reprendre leur position d’origine (comme illustré à la figure 2) en se déplaçant selon la direction d’ouverture/fermeture Z, par exemple lorsque I’actionneur 40 n’est plus en fonctionnement. En effet, les organes de mise en tension 54 des rideaux exerçant continuellement une force sur les rideaux 11 , lesdits rideaux 11 s’enroulent de nouveau autour de leur arbre d’enroulement/déroulement 53 respectif et les éléments dudit système de transmission 20 ainsi que les organes d’entraînement 30 reprennent leur position d’origine. [127] Conversely, the curtains 11 are capable of resuming their original position (as illustrated in FIG. 2) by moving in the opening/closing direction Z, for example when the actuator 40 is no longer in functioning. Indeed, the tensioning members 54 of the curtains continuously exerting a force on the curtains 11, said curtains 11 wind up again around their respective winding/unwinding shaft 53 and the elements of said transmission system 20 as well as the drive members 30 return to their original position.
[128] Le dispositif de régulation 10 à rideaux décrit ci-dessus peut être placé dans un cadre 100 comme décrit sur les figures 4 et 5. [128] The curtain device 10 described above can be placed in a frame 100 as described in Figures 4 and 5.
[129] Ce cadre 100 ménage un espace intérieur 101 dans lequel est placé les rideaux 11 , le cadre 100 comportant une partie avant 110 et une partie arrière 120 assemblées entre elles, la partie avant 110 étant en amont de la partie arrière 120 dans le sens d’écoulement du flux d’air. [129] This frame 100 provides an interior space 101 in which the curtains 11 are placed, the frame 100 comprising a front part 110 and a rear part 120 assembled together, the front part 110 being upstream of the rear part 120 in the air flow direction.
[130] Les parties avant 110 et arrière 120 comportent des passages d’air 111 et 121 pour laisser passer le flux d’air lorsque les deux rideaux 11 sont en position ouverte. [130] The front 110 and rear 120 parts have air passages 111 and 121 to allow the flow of air to pass when the two curtains 11 are in the open position.
[131] La partie arrière 120 comporte une zone de grille 122, de forme plane, qui forme le passage d’air 121. [131] The rear part 120 comprises a grid zone 122, of flat shape, which forms the air passage 121.
[132] La partie arrière 120 du cadre comporte la zone de grille 122 et les rideaux 11 sont agencés pour pouvoir venir s’appuyer sur cette zone de grille 122 lorsque les rideaux 11 sont en positon fermée.
[133] La zone de grille 122, sensiblement de forme rectangulaire, est formée par des barreaux 125 qui se croisent, perpendiculairement. La zone de grille 122 comporte par exemple un groupe de barreaux parallèles entre eux et un autre de barreaux parallèles entre eux et les barreaux des deux groupes se croisent à angle droit. [132] The rear part 120 of the frame includes the grid area 122 and the curtains 11 are arranged to be able to rest on this grid area 122 when the curtains 11 are in the closed position. [133] The grid area 122, substantially rectangular in shape, is formed by bars 125 which intersect perpendicularly. The grid zone 122 comprises for example a group of bars parallel to each other and another of bars parallel to each other and the bars of the two groups intersect at right angles.
[134] La partie arrière 120 comporte une bordure périphérique 127 entourant la zone de grille 122. Cette bordure 127 comporte des nervures de renfort 128, par exemple sur deux côtés 129 parallèles de cette bordure 127. [134] The rear part 120 comprises a peripheral border 127 surrounding the gate zone 122. This border 127 comprises reinforcing ribs 128, for example on two parallel sides 129 of this border 127.
[135] La zone de grille 122 est d’un seul tenant et est dépourvue de montant qui passe en son sein, autre que les barreaux formant la grille. [135] The grating area 122 is in one piece and has no amount that passes through it, other than the bars forming the grate.
[136] La bordure 127 de la partie arrière comporte des parois 135 perpendiculaires à la zone de grille 122. [136] The border 127 of the rear part has walls 135 perpendicular to the grid zone 122.
[137] La partie avant 110 du cadre comporte une ouverture 111 totalement libre, en regard de la zone de grille 122 de la partie arrière, notamment étant sensiblement de même superficie que cette zone de grille. [137] The front part 110 of the frame has a totally free opening 111, opposite the grid zone 122 of the rear part, in particular being substantially of the same area as this grid zone.
[138] La partie avant 110 peut comporter une grille de protection, notamment une grille antiprojectiles, placée dans le passage d’air. [138] The front part 110 may include a protective grid, in particular an anti-projectile grid, placed in the air passage.
[139] La partie avant 110 du cadre comporte une bordure 117 entourant l’ouverture 111 , cette bordure 117 étant agencée pour coopérer avec la bordure127 de la partie arrière 120, ces bordures étant assemblées par des organes de fixation tels que des vis, des organes d’encliquetage, ou de la colle. [139] The front part 110 of the frame comprises a border 117 surrounding the opening 111, this border 117 being arranged to cooperate with the bord127 of the rear part 120, these borders being assembled by fixing elements such as screws, snap-fasteners, or glue.
[140] Les parties avant 110 et arrière 120 du cadre sont formées par moulage d’une matière plastique. [140] The front 110 and rear 120 parts of the frame are formed by molding a plastic material.
[141] Les rideaux 11 , une fois enroulés sur eux-mêmes, occupent un chacun un espace cylindrique qui longe un côté 150 de la bordure des parties avant et arrière, tout en étant à l'intérieur de l’espace délimité par le cadre. [141] The curtains 11, once rolled up on themselves, each occupy a cylindrical space which runs along one side 150 of the border of the front and rear parts, while being inside the space delimited by the frame .
[142] Un actionneur électrique 40 est prévu pour actionner, à savoir enrouler ou dérouler le ou les rideaux 11 . Cet actionneur 40 est ici placé en dehors du cadre 100. [142] An electric actuator 40 is provided to actuate, namely winding or unwinding the curtain or curtains 11 . This actuator 40 is here placed outside the frame 100.
[143] Bien entendu le cadre 100 peut être adapté pour d’autres types de rideaux et/ou de mécanisme d’actionnement des rideaux. [143] Of course, frame 100 can be adapted for other types of curtains and/or curtain operating mechanism.
[144] Ici les rideaux 11 se présentent chacun sous la forme d’une toile enroulable autour d’un axe.
[145] Bien entendu, le dispositif de régulation peut avoir deux rideaux qui sont activables de manière synchronisée, ou en variante n’avoir qu’un seul rideau qui occupe en position fermée toute l’ouverture. [144] Here the curtains 11 are each in the form of a fabric that can be rolled up around an axis. [145] Of course, the regulating device can have two curtains which can be activated in a synchronized manner, or alternatively have only one curtain which occupies the entire opening in the closed position.
[146] On a représenté sur les figures 5 à 8 un dispositif de régulation d’un flux d’air 300 selon un autre exemple de réalisation de l’invention, le dispositif 300 comprenant deux rideaux 11 aptes à se déplacer selon une direction d’ouverture/fermeture, entre une position fermée obturant le passage du flux d’air et une position ouverte laissant passer le flux d’air, ce dispositif de régulation comportant un système de transmission 301 agencé pour guider le mouvement desdits rideaux 11 , ainsi qu’un actionneur 40 induisant un mouvement au système de transmission, ce système de transmission 301 comportant deux arbres d’enroulement 302 et 303 chacun pour l'enroulement et le déroulement de l’un des rideaux 11 , ce système de transmission 301 comportant en outre au moins une courroie 305 actionnable en mouvement et agencée pour faire tourner l’un au moins des arbres d’enroulement à la fois dans le sens d’un enroulement du rideau et dans le sens d’un déroulement du rideau 11. [146] There is shown in Figures 5 to 8 a device for regulating an air flow 300 according to another embodiment of the invention, the device 300 comprising two curtains 11 capable of moving in a direction of opening/closing, between a closed position blocking the passage of the air flow and an open position allowing the air flow to pass, this regulating device comprising a transmission system 301 arranged to guide the movement of said curtains 11, as well as an actuator 40 inducing movement in the transmission system, this transmission system 301 comprising two winding shafts 302 and 303 each for winding and unwinding one of the curtains 11, this transmission system 301 further comprising at least one belt 305 operable in movement and arranged to rotate at least one of the winding shafts both in the direction of winding of the curtain and in the direction of unwinding of the curtain 11.
[147] L’ actionneur 40 est agencé pour faire tourner l’un des arbres d’enroulement, celui 303 sur les figures, sélectivement dans un sens d’enroulement du rideau ou dans un sens de déroulement du rideau 11 . [147] The actuator 40 is arranged to rotate one of the winding shafts, that 303 in the figures, selectively in a winding direction of the curtain or in an unwinding direction of the curtain 11.
[148] Chaque arbre d’enroulement 302 et 303 comporte un pignon denté 310 agencé pour coopérer avec la courroie 305 qui est crantée de sorte que le mouvement de l’arbre d’enroulement 303, un mouvement provoqué par l’actionneur 40, soit transmis à l’autre arbre d’enroulement 302. [148] Each winding shaft 302 and 303 comprises a toothed pinion 310 arranged to cooperate with the belt 305 which is notched so that the movement of the winding shaft 303, a movement caused by the actuator 40, is transmitted to the other winding shaft 302.
[149] Le dispositif de régulation 300 comporte deux courroies 305 chacune à l’une des extrémités des deux arbres d’enroulement 302 et 303 de sorte que chaque courroie 305 est associée à deux pignons dentés 310 des deux arbres d’enroulement, ces deux courroies 305 étant agencées pour être en mouvement synchronisé l’une par rapport à l’autre. [149] The regulating device 300 comprises two belts 305 each at one of the ends of the two winding shafts 302 and 303 so that each belt 305 is associated with two toothed sprockets 310 of the two winding shafts, these two belts 305 being arranged to be in synchronized movement relative to each other.
[150] Le dispositif 300 comporte un organe d’entraînement 320 solidaire d’un bord libre 321 du rideau 11 et agencé pour se déplacer en même temps que les deux courroies 305 pour accompagner le rideau 11 lors de son enroulement ou de son déroulement de manière à maintenir le rideau 11 à plat. [150] The device 300 comprises a drive member 320 secured to a free edge 321 of the curtain 11 and arranged to move at the same time as the two belts 305 to accompany the curtain 11 during its winding or unwinding of so as to maintain the curtain 11 flat.
[151] Chaque organe d’entrainement 320 comporte deux chariots 322 agencés pour être fixés aux deux courroies 305 de sorte que l’organe d’entrainement 320 soit solidaire des deux courroies 305. [151] Each drive member 320 comprises two carriages 322 arranged to be attached to the two belts 305 so that the drive member 320 is integral with the two belts 305.
[152] Chaque chariot 322 est pincé sur la courroie 305 associée, précisément pincé sur une bande 324 formant la courroie.
[153] Pour chaque courroie, le chariot 322 associé à l’un des rideaux est fixé sur un premier brin 328 de la courroie entre les deux arbres d’enroulement 302 et 303 et l’autre chariot associé à l’autre des rideaux est fixé sur un deuxième brin 329 de la courroie qui est opposé au premier brin de sorte que les deux chariots 322 puissent être déplacés en directions opposées, soit en s’éloignant l’un de l’autre soit en se rapprochant l’un de l’autre. [152] Each carriage 322 is pinched on the associated belt 305, precisely pinched on a band 324 forming the belt. [153] For each belt, the carriage 322 associated with one of the curtains is fixed on a first strand 328 of the belt between the two winding shafts 302 and 303 and the other carriage associated with the other of the curtains is fixed to a second strand 329 of the belt which is opposite the first strand so that the two carriages 322 can be moved in opposite directions, either away from each other or towards one another. 'other.
[154] Chaque organe d’entrainement 320 comporte une tige 331 avec à chaque extrémité de la tige 331 l’un des chariots 322, et la tige 331 étant placée le long d’un bord libre 321 du rideau 11 associé. Notamment lorsque les deux rideaux 11 sont en positon fermée, les deux tiges 331 viennent en appui l’une contre l’autre. Les chariots 322 sont notamment fixés sur la courroie sans possibilité de mouvement relatif par rapport à cette courroie. [154] Each drive member 320 comprises a rod 331 with at each end of the rod 331 one of the carriages 322, and the rod 331 being placed along a free edge 321 of the associated curtain 11. In particular when the two curtains 11 are in the closed position, the two rods 331 bear against each other. The carriages 322 are in particular fixed to the belt without the possibility of relative movement with respect to this belt.
[155] Les chariots 322 sont réalisés en matière plastique. [155] The carriages 322 are made of plastic.
[156] Ainsi pour ouvrir ou fermer le rideau, ce rideau 11 est entrainé à la fois par l’arbre d’enroulement et par l’organe d’entrainement, aux deux extrémités. L’action simultanée aux deux extrémités du rideau permet de maintenir ce rideau tendu comme souhaité, évitant ainsi des fronces ou plis et d’éventuels coincements du rideau. [156] Thus to open or close the curtain, this curtain 11 is driven both by the winding shaft and by the drive member, at both ends. Simultaneous action at both ends of the curtain keeps the curtain taut as desired, thus avoiding gathers or folds and possible jamming of the curtain.
[157] Selon l’un des aspects de l’invention, le sens pour enrouler le rideau 11 autour de l’arbre d’enroulement est le même sur les deux arbres. Ceci est permis par le fait que les rideaux s’enroulent de façon opposée sur les deux arbres [157] According to one aspect of the invention, the direction for winding the curtain 11 around the winding shaft is the same on both shafts. This is enabled by the fact that the curtains wrap oppositely on the two shafts
[158] Ainsi les courroies 305 permettent la rotation de l’un des arbres d’enroulement simultanément à la mise en mouvement en translation de l’organe d’entrainement 320 du rideau via les chariots 322. [158] Thus the belts 305 allow the rotation of one of the winding shafts simultaneously with the setting in motion in translation of the drive member 320 of the curtain via the carriages 322.
[159] L’arbre 303 coopère avec l’actionneur 40 via une patte de coopération 340. [159] The shaft 303 cooperates with the actuator 40 via a cooperation leg 340.
[160] On a représenté sur la figure 9 un exemple d’actionneur électrique 40, comme celui décrit en référence à la figure 6. [160] There is shown in Figure 9 an example of an electric actuator 40, like the one described with reference to Figure 6.
[161] Le dispositif de régulation 300 comporte un cadre 361 pour loger les rideaux 11. [161] The regulating device 300 comprises a frame 361 to house the curtains 11.
[162] Ce cadre 361 comporte une partie avant 362 et une partie arrière 363, la partie avant[162] This frame 361 comprises a front part 362 and a rear part 363, the front part
362 étant placée en amont par rapport à la partie arrière 363 suivant le sens du flux d’air, ce cadre 361 comportant un boitier 365 en association avec l’actionneur 40. 362 being placed upstream with respect to the rear part 363 following the direction of the air flow, this frame 361 comprising a box 365 in association with the actuator 40.
[163] Ce boitier 365 reçoit notamment un moteur électrique, non visible sur les figure, de l’actionneur 40, ce boitier 365 comportant une partie de boitier 366 formée d’un seul tenant avec la partie avant 362 du cadre et une autre partie de boitier 367 formée avec la partie arrière[163] This box 365 receives in particular an electric motor, not visible in the figures, of the actuator 40, this box 365 comprising a part of the box 366 formed in one piece with the front part 362 of the frame and another part of case 367 formed with the rear part
363 du cadre.
[164] Les deux parties de boitier 366 et 367 sont assemblées de manière étanche, avec interposition d’un joint entre ces parties de boitier. 363 of the frame. [164] The two housing parts 366 and 367 are assembled in a sealed manner, with the interposition of a seal between these housing parts.
[165] Les parties de boitier 366 et 367 forment un logement 368 pour le moteur électrique et l’une au moins des parties de boitier 366 ou 367 comporte un capot 369 fermant ce logement 368, ce capot 369 et la partie de boitier associée étant formés d’un seul tenant. [165] The housing parts 366 and 367 form a housing 368 for the electric motor and at least one of the housing parts 366 or 367 includes a cover 369 closing this housing 368, this cover 369 and the associated housing part being formed in one piece.
[166] Le capot 369 du boitier est plan. [166] The cover 369 of the box is flat.
[167] Le cadre 361 comporte une bordure 370 et le boitier 365 de l’actionneur est placé sur cette bordure 370. [167] The frame 361 has a border 370 and the housing 365 of the actuator is placed on this border 370.
[168] Les parties de boitier 366 et 367 sont formées respectivement avec un barreau 371 de la partie avant ou arrière du cadre, ces barreaux formant ensemble la bordure 370 du cadre qui est en contact avec le boitier 365 de l’actionneur. [168] The housing parts 366 and 367 are formed respectively with a bar 371 of the front or rear part of the frame, these bars together forming the edge 370 of the frame which is in contact with the housing 365 of the actuator.
[169] Le boitier 365 s’étend sur moins de la moitié de la longueur des barreaux 371, notamment moins d’un tiers, voire un quart, de cette longueur. [169] The box 365 extends over less than half the length of the bars 371, in particular less than a third, or even a quarter, of this length.
[170] Un orifice 372 est prévu dans le fond du boitier 365 pour le passage d’un élément d’engrenage par exemple, vers les rideaux. [170] A hole 372 is provided in the bottom of the box 365 for the passage of a gear element, for example, towards the curtains.
[171] Les parties de boitier 366 et 367 de l’actionneur sont formées par moulage ou comoulage avec les parties avant et arrière 362 et 363 respectives du cadre, comme on peut mieux le voir sur le figures 10 et 11. [171] The housing parts 366 and 367 of the actuator are formed by molding or co-molding with the respective front and rear parts 362 and 363 of the frame, as best seen in Figures 10 and 11.
[172] Les parties avant et arrière 362 et 363 du cadre sont assemblées avec des éléments d’encliquetage 377. [172] The front and rear parts 362 and 363 of the frame are assembled with snap elements 377.
[173] L’une au moins des parties avant et arrière 362 et 363 du cadre comporte un grillage 378, notamment en forme de nid d’abeille, réalisé notamment par moulage avec cette partie de cadre. [173] At least one of the front and rear parts 362 and 363 of the frame comprises a mesh 378, in particular in the form of a honeycomb, produced in particular by molding with this part of the frame.
[174] Le boitier 365 de l’actionneur comporte au moins un orifice 379 pour le passage d’un élément de connexion électrique, notamment pour le moteur de l’actionneur. [174] The housing 365 of the actuator has at least one hole 379 for the passage of an electrical connection element, in particular for the motor of the actuator.
[175] Les parties avant et arrière du cadre sont assemblées avec des éléments d’encliquetage 391 et 392 qui forment une paire 377 d’éléments d’encliquetage. [175] The front and rear parts of the frame are assembled with snap elements 391 and 392 which form a pair 377 of snap elements.
[176] Les deux parties de boitier 366 et 367 sont assemblées de manière étanche, avec notamment interposition d’un joint entre ces parties de boitier. [176] The two housing parts 366 and 367 are assembled in a sealed manner, in particular with the interposition of a seal between these housing parts.
[177] L’élément d’encliquetage 391 comporte une patte d’encliquetage déformable agencée pour coopérer avec l’autre élément d’encliquetage 392.
[178] La patte d’encliquetage 391 comporte une ouverture pour coopérer avec l’autre élément d’encliquetage 392 qui comporte un bossage. [177] The latching element 391 comprises a deformable latching tab arranged to cooperate with the other latching element 392. [178] The latching tab 391 has an opening to cooperate with the other latching element 392 which has a boss.
[179] Le cadre comporte une pluralité de paires d’éléments d’encliquetage 391 et 392 répartis sur les quatre côtés du pourtour de ce cadre. [179] The frame comprises a plurality of pairs of latching elements 391 and 392 distributed on the four sides of the circumference of this frame.
[180] Le cadre comporte une bordure 370 et le boitier de l’actionneur est placé sur cette bordure. [180] The frame has a border 370 and the actuator box is placed on this border.
[181] Les éléments d’encliquetage présentent des dimensions inférieures aux dimensions de la bordure 370 de sorte que les éléments d’encliquetage restent dans une largeur de cette bordure. [181] The snap elements have dimensions smaller than the dimensions of the border 370 so that the snap elements remain within a width of this border.
[182] Les éléments d’encliquetage sont formés d’un seul tenant avec les parties de cadre respectives. [182] The snap elements are formed integrally with the respective frame parts.
[183] Ainsi les parties avant et arrière du cadre sont assemblées sans l’aide de vis ou de boulons. [183] Thus the front and rear parts of the frame are assembled without the aid of screws or bolts.
[184] On a représenté sur la figure 12 un dispositif de régulation d’un flux d’air 400 comprenant au moins un rideau souple 11 apte à se déplacer selon une direction d’ouverture/fermeture, entre une position fermée obturant le passage du flux d’air et une position ouverte laissant passer le flux d’air F, comme dans les exemples décrits ci-dessus. [184] There is shown in Figure 12 a device for regulating an air flow 400 comprising at least one flexible curtain 11 able to move in an opening / closing direction, between a closed position closing the passage of the flow of air and an open position allowing the flow of air F to pass, as in the examples described above.
[185] Le rideau 11 comporte un bord libre 401 solidaire, à l’aide d’un dispositif de fixation 402, de l’un d’un arbre d’enroulement 403, ayant la même fonction que l’arbre 53 décrit ci- dessus, ou d’un organe d’entrainement 405 coulissant ayant la même fonction que l’organe d’entrainement 320 décrit ci-dessus. [185] The curtain 11 has a free edge 401 secured, using a fixing device 402, to one of a winding shaft 403, having the same function as the shaft 53 described above. above, or a sliding drive member 405 having the same function as the drive member 320 described above.
[186] La figure 12 décrit le cas de l’organe d’entrainement 405. [186] Figure 12 describes the case of drive member 405.
[187] Le dispositif de fixation 402 du rideau comporte deux éléments 410 et 411 agencés pour coincer une portion du rideau 412 entre ces deux éléments. [187] The fixing device 402 of the curtain comprises two elements 410 and 411 arranged to wedge a portion of the curtain 412 between these two elements.
[188] Les deux éléments 410 et 411 du dispositif de fixation 402 font partie de de l’organe d’entrainement 405 sur lequel est fixé le bord libre 401 du rideau 11. [188] The two elements 410 and 411 of the fixing device 402 are part of the drive member 405 on which is fixed the free edge 401 of the curtain 11.
[189] Le bord libre 401 du rideau qui est fixé sur le dispositif de fixation 402 est rectiligne et les éléments 410 et 411 entre lesquels est coincée la portion de rideau s’étendent parallèlement à ce bord libre rectiligne 401. [189] The free edge 401 of the curtain which is fixed to the fixing device 402 is straight and the elements 410 and 411 between which the curtain portion is wedged extend parallel to this straight free edge 401.
[190] Les éléments de fixation 410 et 411 présentent des faces de coincement respectivement 413 et 414 entre lesquelles est coincée la portion 412 de rideau.
[191] Les faces de coincement 413 et 414 présentent des formes complémentaires entre lesquelles est placée la portion 412 de rideau à coincer. [190] The fixing elements 410 and 411 have wedging faces respectively 413 and 414 between which the portion 412 of the curtain is wedged. [191] The wedging faces 413 and 414 have complementary shapes between which is placed the portion 412 of the curtain to be wedged.
[192] Les faces de coincement 413 et 414 présentent des formes sensiblement arrondies de sorte que la portion 412 de rideau coincée s’enroule autour de la face 413 d’enroulement, sur un secteur angulaire seulement. [192] The wedging faces 413 and 414 have substantially rounded shapes so that the wedged portion 412 of the curtain wraps around the winding face 413, over an angular sector only.
[193] Les deux éléments 410 et 411 définissent entre eux une fente d’entrée 415 pour la portion 412 de rideau, et le rideau est coincé entre les deux éléments 410 et 411 depuis la fente d’entrée 415 jusqu’au bord libre 401 du rideau, formant la portion 412 coincée du rideau. [193] The two elements 410 and 411 define between them an entry slot 415 for the curtain portion 412, and the curtain is wedged between the two elements 410 and 411 from the entry slot 415 to the free edge 401 of the curtain, forming the wedged portion 412 of the curtain.
[194] Les éléments 410 et 411 du dispositif de fixation sont assemblés ensemble par encliquetage. [194] The elements 410 and 411 of the fastening device are assembled together by snap-fastening.
[195] En particulier l’élément 411 comporte un resserrement 417 qui est franchi par l’autre élément 410 au moment de l’assemblage, et ce resserrement 417 se remet en place et emprisonne l’élément complémentaire 410. [195] In particular, element 411 has a constriction 417 which is crossed by the other element 410 at the time of assembly, and this constriction 417 goes back into place and traps the complementary element 410.
[196] L’élément 410 du dispositif de fixation comporte un tube creux 418 sur lequel est formé la face de coincement 413. [196] The element 410 of the fixing device comprises a hollow tube 418 on which the wedging face 413 is formed.
[197] Ce tube creux 418 est logé dans un logement cylindrique 419 de l’autre élément 411 du dispositif de fixation, ce logement 419 présentant le resserrement 417 pour emprisonner le tube creux. [197] This hollow tube 418 is housed in a cylindrical housing 419 of the other element 411 of the fixing device, this housing 419 having the tightening 417 to trap the hollow tube.
[198] Dans ce cas, le tube creux 418 est agencé pour franchir le resserrement 417 du cylindre grâce à une déformation de l’élément correspondant 411 , par écartement de deux lèvres 420 qui forment les deux rebords ou lèvres 420 de ce resserrement 417. Puis une fois que le tube creux 418 a franchi le resserrement 417, les deux lèvres 420 se rapprochent par déformation élastique pour emprisonner le tube creux 418. Il s’agit d’un assemblage par encliquetage. [198] In this case, the hollow tube 418 is arranged to cross the constriction 417 of the cylinder thanks to a deformation of the corresponding element 411, by separating two lips 420 which form the two edges or lips 420 of this constriction 417. Then once the hollow tube 418 has crossed the constriction 417, the two lips 420 come together by elastic deformation to trap the hollow tube 418. This is a snap-fit assembly.
[199] Dans cet exemple, la portion de rideau 412 ne recouvre pas une face extérieure des éléments 410 et 411 du dispositif de fixation. [199] In this example, the curtain portion 412 does not cover an outer face of the elements 410 and 411 of the fastening device.
[200] Dans cet exemple, le rideau ne s’enroule pas autour des éléments 410 et 411 du dispositif de fixation, qui est coulissant en translation, et non rotatif. Ce dispositif de fixation 402 fait partie de l’organe d’entrainement du rideau. [200] In this example, the curtain does not wrap around the elements 410 and 411 of the fixing device, which is sliding in translation, and not rotatable. This fixing device 402 is part of the drive member of the curtain.
[201] Dans l’exemple illustré à la figure 13, les éléments de fixation 430 et 431 du dispositif de fixation 425 comportent chacun une face extérieure respectivement 432 et 433 sur lesquelles s’appuie le rideau 11 , pour permettre au rideau 11 de s’enrouler autour de ces deux faces extérieures 432 et 433 qui définissent une surface cylindrique.
[202] Dans cet exemple, le dispositif de fixation 425 du rideau fait partie de l’arbre d’enroulement 403. [201] In the example illustrated in Figure 13, the fixing elements 430 and 431 of the fixing device 425 each have an outer face respectively 432 and 433 on which the curtain 11 rests, to allow the curtain 11 to s wrap around these two outer faces 432 and 433 which define a cylindrical surface. [202] In this example, the fixing device 425 of the curtain is part of the winding shaft 403.
[203] L’élément 430 du dispositif de fixation 425 comporte un tube creux 436 et, de part et d’autre de ce tube creux, deux extensions 437, et la face de coincement 438 est formée sur ce tube creux 436 et les extensions 437. L’autre face de coincement 439 est formé sur l’élément 431. [203] The element 430 of the fixing device 425 comprises a hollow tube 436 and, on either side of this hollow tube, two extensions 437, and the wedging face 438 is formed on this hollow tube 436 and the extensions 437. The other wedging face 439 is formed on element 431.
