Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

L'invention concerne un dispositif d'entrainement motorisé d'une structure mobile, tel que par exemple un dispositif d'entrainement motorisé pour l'ouverture et la fermeture d'abris pour piscine.The invention relates to a motorized drive device of a mobile structure, such as for example a motorized drive device for opening and closing swimming pool shelters.

ETAT DE LA TECHNIQUESTATE OF THE ART

On connaît des structures d'abris pour piscine, de type télescopiques, qui comprennent une pluralité de modules d'abris. Les modules sont mobiles par rapport au sol de sorte que la structure peut être rétractée pour découvrir le bassin ou déployée pour recouvrir le bassin. Chaque module d'abris comprend une couverture destinée à recouvrir le bassin et une armature ayant pour fonction de soutenir la couverture.Swimming pool enclosures of the telescopic type are known which comprise a plurality of shelter modules. The modules are movable relative to the ground so that the structure can be retracted to discover the pool or deployed to cover the pool. Each shelter module includes a cover for covering the pool and a frame for supporting the cover.

Ces modules incluent également des roues facilitant leur déplacement par rapport au sol. Les roues sont généralement montées sur des traverses s'étendant le long d'un côté du bassin et faisant partie de l'armature.These modules also include wheels facilitating their movement relative to the ground. The wheels are generally mounted on sleepers extending along one side of the pool and forming part of the frame.

Certaines structures d'abris sont également équipées d'une motorisation adaptée pour entrainer en rotation les roues de l'un des modules afin d'automatiser le déplacement des modules.Some shelter structures are also equipped with a motor adapted to rotate the wheels of one of the modules in order to automate the movement of the modules.

Cependant, la présence d'une motorisation nécessite l'installation d'un boîtier spécifique destiné à loger le moteur, le boîtier étant généralement rapporté sur une paroi latérale d'un module. La présence d'un tel boîtier peut être considérée comme peu esthétique.However, the presence of a motorization requires the installation of a specific housing for housing the motor, the housing being generally attached to a side wall of a module. The presence of such a housing can be considered unattractive.

On connait par ailleurs du document FR 2 882 779 un dispositif d'ouverture et de fermeture d'une structure mobile par rapport à une surface (telle que la surface du sol), comprenant au moins deux roues destinées à être mises en contact avec la surface, un moteur pour entrainer en rotation les deux roues, et un ensemble réducteur par l'intermédiaire duquel le moteur est apte à entrainer en rotation les deux roues.We also know of the document FR 2 882 779 a device for opening and closing a movable structure with respect to a surface (such as the ground surface), comprising at least two wheels intended to be brought into contact with the surface, a motor for rotating the two wheels, and a reduction unit through which the motor is adapted to drive in rotation the two wheels.

  • chaque pignon de plus petit diamètre engrène avec un pignon de plus grand diamètre de sorte que la vitesse de rotation de la roue est inférieure à la vitesse de rotation de l'arbre d'entrée,
  • l'arbre de sortie s'étend selon une direction perpendiculaire à une direction de l'arbre d'entrée,
  • l'ensemble de transmission comprend un dispositif d'embrayage adapté pour sélectivement accoupler l'arbre d'entrée et l'arbre de sortie lorsque l'arbre d'entrée est entraîné en rotation par le moteur et désaccoupler l'arbre d'entrée et l'arbre de sortie lorsque l'arbre d'entrée n'est pas entraîné en rotation par le moteur.
The device can furthermore have the following characteristics:

L'ensemble mécanique de transmission 27 comprend en outre un dispositif d'embrayage 44 agencé entre l'arbre d'entrée 31 (constituant la pièce motrice) et le premier pignon conique 32 (constituant la pièce réceptrice). Le dispositif d'embrayage 44 est un dispositif d'embrayage centrifuge, c'est-à-dire apte qu'il est adapté pour sélectivement accoupler l'arbre d'entrée 31 et le premier pignon conique 32 lorsque l'arbre d'entrée 31 est entraîné en rotation par le moteur 26 et désaccoupler l'arbre d'entrée 31 et le premier pignon conique 32 lorsque l'arbre d'entrée 31 n'est pas entraîné en rotation par le moteur 26.The mechanical transmission unit 27 further comprises a clutch device 44 arranged between the input shaft 31 (constituting the driving part) and the first conical pinion 32 (constituting the receiving part). The clutch device 44 is a centrifugal clutch device, that is to say capable of being adapted to selectively couple the input shaft 31 and the first bevel gear 32 when the input shaft 31 is rotated by the motor 26 and uncoupling the input shaft 31 and the first bevel gear 32 when the input shaft 31 is not rotated by the motor 26.

Chaque demi-boîtier 29, 30 comprend une patte de fixation 45, 46 destinée à être fixée sur une face du carter du moteur 26, de sorte que lorsque les deux demi-boîtiers 29, 30 sont assemblés, les pattes de fixation 45, 46 s'étendent de part et d'autre du moteur 26 pour maintenir le moteur 26 sur l'ensemble mécanique de transmission 27.Each half-housing 29, 30 comprises a fixing lug 45, 46 intended to be fixed on one face of the housing of the motor 26, so that when the two half-housings 29, 30 are assembled, the fixing lugs 45, 46 extend on either side of the motor 26 to maintain the motor 26 on the mechanical transmission unit 27.

L'arbre d'entrée 31 s'étend selon une direction parallèle à une direction longitudinale du profilé formant la traverse 11.The input shaft 31 extends in a direction parallel to a longitudinal direction of the section forming the cross-member 11.

Les deux demi-boîtiers 29 et 30 supportent les arbres intermédiaires 34, 37 et 43, et l'arbre de sortie 40. Les arbres intermédiaires 34, 37 et 43 et l'arbre de sortie 40 s'étendent parallèlement les uns aux autres, dans une direction générale perpendiculaire à l'arbre d'entrée 31 et parallèle à l'arbre 25 supportant la roue 13. De plus, les arbres intermédiaires 34, 37 et 43 sont montés fixes par rapport au boîtier 28.The two half-housings 29 and 30 support the intermediate shafts 34, 37 and 43, and the output shaft 40. The intermediate shafts 34, 37 and 43 and the output shaft 40 extend parallel to each other, in a general direction perpendicular to the input shaft 31 and parallel to the shaft 25 supporting the wheel 13. In addition, the intermediate shafts 34, 37 and 43 are mounted fixed relative to the housing 28.

L'arbre de sortie 40 est monté rotatif par rapport au boîtier 28. L'arbre de sortie 40 présente deux portions d'extrémité 47, 47' qui font saillie à l'extérieur du boîtier 28. L'arbre de sortie 40 s'étend donc à travers les parois des demi-boîtiers 29 et 30.The output shaft 40 is rotatably mounted relative to the housing 28. The output shaft 40 has two end portions 47, 47 'which protrude outside the housing 28. The output shaft 40 is extends therefore through the walls of the half-housings 29 and 30.

L'arbre intermédiaire 43 présente également deux portions d'extrémité 48, 48' qui font saillie à l'extérieur du boîtier 28. L'arbre intermédiaire 43 s'étend également à travers les parois des demi-boîtiers 29 et 30.The intermediate shaft 43 also has two end portions 48, 48 'which protrude outside the housing 28. The shaft intermediate 43 also extends through the walls of the half-housings 29 and 30.

L'arbre d'entrée 31 est accouplé à une sortie du moteur 26 et supporte le premier pignon conique 32.The input shaft 31 is coupled to an output of the motor 26 and supports the first conical gear 32.

Le premier arbre intermédiaire 34 supporte le deuxième pignon conique 33 et le premier pignon cylindrique 35.The first intermediate shaft 34 supports the second bevel gear 33 and the first cylindrical gear 35.

Le deuxième arbre intermédiaire 37 supporte le deuxième pignon cylindrique 36 et le troisième pignon cylindrique 38.The second intermediate shaft 37 supports the second cylindrical gear 36 and the third cylindrical gear 38.

L'arbre de sortie 40 supporte le quatrième pignon conique 39, le cinquième pignon cylindrique 41 et le septième pignon cylindrique 41', les pignons 39, 41 et 41' étant montés solidaire en rotation de l'arbre 40. Le cinquième pignon cylindrique 41 et le septième pignon cylindrique 41' sont montés respectivement à l'extrémité 47 et à l'extrémité 47' du troisième arbre intermédiaire 40, les pignons 41 et 41' s'étendant à l'extérieur du boîtier 28.The output shaft 40 supports the fourth bevel gear 39, the fifth cylindrical gear 41 and the seventh cylindrical gear 41 ', the pinions 39, 41 and 41' being mounted integral in rotation with the shaft 40. The fifth cylindrical gear 41 and the seventh cylindrical gear 41 'are respectively mounted at the end 47 and the end 47' of the third intermediate shaft 40, the gears 41 and 41 'extending outside the housing 28.

L'arbre intermédiaire 43 supporte à la fois le sixième pignon cylindrique 42 et le huitième pignon cylindrique 42'. Le sixième pignon cylindrique 42 et le huitième pignon cylindrique 42' sont montés respectivement à l'extrémité 48 et à l'extrémité 48' de l'arbre de sortie 43, les pignons 42 et 42' s'étendant à l'extérieur du boîtier 28.The intermediate shaft 43 supports both the sixth cylindrical gear 42 and the eighth cylindrical gear 42 '. The sixth cylindrical gear 42 and the eighth cylindrical gear 42 'are respectively mounted at the end 48 and the end 48' of the output shaft 43, the gears 42 and 42 'extending outside the housing 28.

Les pignons 41, 41', 42, 42', 49 et 49' situés à l'extérieur du boîtier 28 peuvent être formés en métal, tel que de l'acier, tandis que les pignons 32, 33, 35, 36, 38, 39 situés à l'intérieur du boîtier 28 peuvent être formés en matière plastique, tel qu'un polyoxyméthylène (POM).The pinions 41, 41 ', 42, 42', 49 and 49 'located outside the housing 28 may be formed of metal, such as steel, while the pinions 32, 33, 35, 36, 38 , 39 located inside the housing 28 may be formed of plastic, such as polyoxymethylene (POM).

Le dispositif d'embrayage 44 est apte à sélectivement mettre en prise le premier pignon conique 32 avec l'arbre d'entrée 31 ou libérer le premier pignon conique 32 de l'arbre d'entrée 31 de manière à ce que le premier pignon conique 32 soit libre en rotation autour de l'arbre d'entrée 31.The clutch device 44 is adapted to selectively engage the first bevel gear 32 with the input shaft 31 or release the first bevel gear 32 from the input shaft 31 so that the first bevel gear 32 is free to rotate around the input shaft 31.

Le premier pignon conique 32 engrène avec le deuxième pignon conique 33, le deuxième pignon conique étant monté rotatif par rapport au premier arbre intermédiaire 34 qui le porte. Les pignons coniques 32 et 33 forment un renvoi d'angle. Les pignons coniques 32 et 33 permettent ainsi de lier l'arbre d'entrée 31 à l'arbre de sortie 40, l'arbre d'entrée 31 étant rotatif autour d'un axe de rotation sensiblement perpendiculaire à l'axe de rotation de l'arbre de transmission 40.The first bevel gear 32 meshes with the second bevel gear 33, the second bevel gear being rotatably mounted relative to the first intermediate shaft 34 which carries it. The bevel gears 32 and 33 form a bevel gear. The bevel gears 32 and 33 thus allow to connect the input shaft 31 to the output shaft 40, the input shaft 31 being rotatable about an axis of rotation substantially perpendicular to the axis of rotation of the transmission shaft 40.

Le deuxième pignon conique 33 est monté rotatif autour du premier arbre intermédiaire 34 et est solidaire du premier pignon cylindrique 35, le premier pignon cylindrique 35 étant également monté rotatif autour du premier arbre intermédiaire 34.The second conical gear 33 is rotatably mounted around the first intermediate shaft 34 and is integral with the first cylindrical gear 35, the first cylindrical gear 35 also being rotatably mounted around the first intermediate shaft 34.

Le premier pignon cylindrique 35 engrène avec le deuxième pignon cylindrique 36. Le deuxième pignon cylindrique 36 est monté rotatif autour du deuxième arbre intermédiaire 37 qui le porte. Le deuxième pignon cylindrique 36 est solidaire du troisième pignon cylindrique 38 qui est également monté rotatif sur le deuxième arbre intermédiaire 37.The first cylindrical gear 35 meshes with the second cylindrical gear 36. The second cylindrical gear 36 is rotatably mounted around the second intermediate shaft 37 which carries it. The second cylindrical gear 36 is integral with the third cylindrical gear 38 which is also rotatably mounted on the second intermediate shaft 37.

Le troisième pignon cylindrique 38 engrène avec le quatrième pignon cylindrique 39. Le quatrième pignon cylindrique 39 est monté de manière solidaire sur l'arbre de sortie 40. Les pignons 41 et 41' sont également montés solidaires de l'arbre de sortie 40.The third cylindrical gear 38 meshes with the fourth cylindrical gear 39. The fourth cylindrical gear 39 is integrally mounted on the output shaft 40. The gears 41 and 41 'are also mounted integral with the output shaft 40.

Les cinquième et septième pignons 41 et 41' engrènent respectivement avec les sixième et huitième pignons 42 et 42'. Les sixième et huitième pignons 42 et 42' sont montés rotatifs autour de l'arbre intermédiaire 43.The fifth and seventh gears 41 and 41 'mesh respectively with the sixth and eighth gears 42 and 42'. The sixth and eighth gears 42 and 42 'are rotatably mounted around the intermediate shaft 43.

Les sixième et huitième pignons 42 et 42' engrènent respectivement avec les neuvième et dixième pignons 49 et 49'. Les neuvième et dixième pignons 49 et 49' sont montés rotatifs autour de l'arbre de roue 25. Les neuvième et dixième pignons 49 et 49' sont positionnés de part et d'autre de la roue 13 en étant solidaires de la roue 13.The sixth and eighth gears 42 and 42 'mesh respectively with the ninth and tenth gears 49 and 49'. The ninth and tenth gears 49 and 49 'are rotatably mounted around the wheel shaft 25. The ninth and tenth gears 49 and 49' are positioned on either side of the wheel 13 while being integral with the wheel 13.

Ainsi, les neuvième et dixième pignons 49 et 49' sont montés rotatifs autour d'une axe de rotation commun et entrainent tous les deux en rotation la roue 13.Thus, the ninth and tenth gears 49 and 49 'are rotatably mounted about a common axis of rotation and both cause the wheel 13 to rotate.

En fonctionnement, lorsque le moteur 26 est mis en marche, le moteur 26 entraîne en rotation l'arbre d'entrée 31. Cela a pour effet de mettre en prise le dispositif d'embrayage 44.In operation, when the motor 26 is turned on, the motor 26 rotates the input shaft 31. This has the effect of engaging the clutch device 44.

Le dispositif d'embrayage 44 est alors en position embrayée. Dans cette position, l'arbre d'entrée 31 entraîne en rotation l'arbre de sortie 40 par l'intermédiaire des pignons 32, 33, 35, 36, 38, et 39.The clutch device 44 is then in the engaged position. In this position, the input shaft 31 rotates the output shaft 40 via pinions 32, 33, 35, 36, 38, and 39.

L'arbre de sortie 40 entraîne en rotation la roue 13 par l'intermédiaire des pignons 41, 42, 49 et 41', 42', 49' respectivement.The output shaft 40 rotates the wheel 13 through the pinions 41, 42, 49 and 41 ', 42', 49 'respectively.

On notera que les pignons de plus petit diamètre 35, 38, 41, 41' sont montés solidaires en rotation de pignons de plus grand diamètre 33, 36, 39. De plus, chaque pignon de plus petit diamètre 44, 35, 38, 41, 41' engrène avec un pignon de plus grand diamètre 33, 36, 39, 42, 42' de sorte que la vitesse de rotation de la roue 13 est inférieure à la vitesse de rotation de l'arbre d'entrée 44. L'ensemble de transmission 27 fonctionne ainsi comme un réducteur.It will be noted that the smaller-diameter pinions 35, 38, 41, 41 'are mounted integral in rotation with larger-diameter pinions 33, 36, 39. In addition, each pinion of smaller diameter 44, 35, 38, 41 , 41 'meshes with a larger diameter pinion 33, 36, 39, 42, 42' so that the speed of rotation of the wheel 13 is less than the rotational speed of the input shaft 44. The Transmission unit 27 thus functions as a reducer.

La roue 13 est ainsi entrainée simultanément en rotation par les deux chaînes de pignons 41, 42, 49 et 41', 42', 49' agencées symétriquement de part et d'autre de la roue 13. Autrement dit, les deux chaînes de pignons 41, 42, 49 et 41', 42', 49' agissent en parallèle sur la roue 13 pour entrainer la roue 13 en rotation. Du fait de la symétrie entre les deux chaînes de pignons, les efforts exercés sur l'arbre 25 de la roue via les pignons 41, 42, 49 et 41', 42', 49' sont symétriques et se compensent mutuellement.The wheel 13 is thus driven simultaneously in rotation by the two chains of pinions 41, 42, 49 and 41 ', 42', 49 'arranged symmetrically on either side of the wheel 13. In other words, the two chains of sprockets 41, 42, 49 and 41 ', 42', 49 'act in parallel on the wheel 13 to drive the wheel 13 in rotation. Because of the symmetry between the two chains of sprockets, the forces exerted on the shaft 25 of the wheel via the sprockets 41, 42, 49 and 41 ', 42', 49 'are symmetrical and compensate each other.

Cela a pour avantage que le dispositif d'entrainement 17 peut être fabriqué à partir de composants (arbres et pignons) de petite taille pouvant être logés à l'intérieur du profilé, malgré le couple important s'exerçant sur la roue 13.This has the advantage that the drive device 17 can be made from components (shafts and pinions) of small size that can be housed inside the profile, despite the significant torque exerted on the wheel 13.

On remarquera que les pignons cylindriques 41, 41', 42 et 42' sont disposés à l'extérieur du boîtier 28, de sorte que les pignons cylindriques 41, 41', 42 et 42' peuvent facilement être remplacés en vue d'ajuster la vitesse d'entraînement de la roue 13.It will be noted that the cylindrical gears 41, 41 ', 42 and 42' are disposed outside the housing 28, so that the cylindrical gears 41, 41 ', 42 and 42' can easily be replaced to adjust the wheel drive speed 13.

Les pignons 441, 41', 42 et 42' sont accessibles à un opérateur et leur changement ne nécessite pas d'ouvrir le boîtier 28. Ainsi, lors de l'installation du dispositif d'entrainement, un opérateur peut choisir des pignons adaptés au type de structure d'abris à déplacer.The pinions 441, 41 ', 42 and 42' are accessible to an operator and their change does not require opening the housing 28. Thus, during the installation of the drive device, an operator can choose gears adapted to the operator. type of shelter structure to move.

Lorsque le moteur 26 est désactivé, le dispositif d'embrayage 44 revient en position débrayée et l'arbre d'entrée 31 n'est plus en prise avec le premier pignon conique 32. La roue 13 du dispositif peut tourner sans entrainer le moteur 26, ce qui facilite une manipulation manuelle de la structure d'abris sur laquelle est monté le dispositif d'entrainement 17.When the motor 26 is deactivated, the clutch device 44 returns to the disengaged position and the input shaft 31 is no longer in engagement with the first conical gear 32. The wheel 13 of the device can rotate without driving the motor 26 , which facilitates manual manipulation of the shelter structure on which the drive device 17 is mounted.
