    • a drive mechanism having a first freewheel coupling connected to the winding drum, a second freewheel coupling connected to the rolling elements, and a drive motor connected to the first and second freewheeling clutches and rolling through an endless transmission element, the first overrunning coupling being movable between an engaged state in which the first overrunning coupling is adapted to transmit a rotational torque to the winding drum and a state disengaged wherein the first overrunning clutch is unable to transmit rotational torque to the take-up drum, and the second overrunning clutch being movable between an engaged state in which the second clutch is capable of transmitting torque of rotation to the rolling elements and a disengaged state in which the second wheel coupling free is unable to transmit a rotational torque to the rolling elements.

Un tel mécanisme d'entraînement est plus particulièrement configuré de telle sorte que :

  • une rotation du moteur d'entraînement dans un premier sens de rotation de moteur entraîne un déplacement du premier accouplement à roue libre dans l'état débrayé et un déplacement du deuxième accouplement à roue libre dans l'état embrayé, et entraîne ainsi une rotation des éléments de roulement dans un premier sens de rotation de manière à déplacer la partie de support dans un sens de déroulement de la couverture de bassin, et
  • une rotation du moteur d'entraînement dans un deuxième sens de rotation de moteur, opposé au premier sens de rotation de moteur, entraîne un déplacement du premier accouplement à roue libre dans l'état embrayé et un déplacement du deuxième accouplement à roue libre dans l'état débrayé, et entraîne ainsi une rotation du tambour d'enroulement dans le deuxième sens de rotation de manière à déplacer la partie de support dans un sens d'enroulement de la couverture de bassin.
Such a drive mechanism is more particularly configured such that:
  • a rotation of the drive motor in a first direction of motor rotation causes a displacement of the first freewheeling coupling in the disengaged state and a displacement of the second freewheeling coupling in the engaged state, and thus causes rotation of the rolling elements in a first direction of rotation so as to move the support portion in a direction of unwinding of the basin cover, and
  • a rotation of the drive motor in a second direction of motor rotation, opposite to the first direction of motor rotation, causes a displacement of the first overrunning clutch in the engaged state and a displacement of the second overrunning clutch in the state disengaged, and thus causes a rotation of the winding drum in the second direction of rotation so as to move the support portion in a winding direction of the basin cover.

Cependant, lors de l'enroulement de la couverture de bassin, la partie menée du deuxième accouplement à roue libre, qui est solidaire en rotation des éléments de roulement est susceptible d'être entraînée en rotation, en fonction des diamètres des éléments de roulement et du diamètre du tambour d'enroulement qui évolue au cours de la phase d'enroulement de la couverture de bassin, à une vitesse de rotation pouvant induire le passage du deuxième accouplement à roue libre dans l'état embrayé. Or, un tel passage du deuxième accouplement à roue libre dans l'état embrayé lors de l'enroulement de la couverture de bassin, alors que les éléments de roulement roulent sur les surfaces de roulement disposées de part et d'autre du bassin, nuit à la qualité de l'enroulement de la couverture de bassin, mais également à la fiabilité du mécanisme d'entraînement, puisqu'il peut induire une usure, voire une rupture de certains éléments du mécanisme d'entraînement, tels que les premier et deuxième accouplements à roue libre et l'élément de transmission sans fin.However, during the winding of the pool cover, the driven portion of the second freewheel coupling, which is rotatably integral with the rolling elements, is capable of being rotated, depending on the diameters of the rolling elements and the diameter of the winding drum that evolves during the winding phase of the pond cover, at a speed of rotation that can induce the passage of the second freewheel coupling in the engaged state. However, such a passage of the second freewheel coupling in the engaged state during the winding of the pool cover, while the rolling elements roll on the rolling surfaces arranged on either side of the basin, night the quality of the winding of the pool cover, but also the reliability of the drive mechanism, since it can induce wear or even breakage of certain elements of the drive mechanism, such as the first and second freewheel couplings and the endless transmission element.

Un tel chariot de support est complexe et onéreux. En outre, un tel chariot de support comporte de nombreuses pièces susceptibles d'être défaillantes, ce qui nuit à la fiabilité du chariot de support et donc du système de recouvrement.Such a support carriage is complex and expensive. In addition, such a support carriage has many parts likely to be faulty, which affects the reliability of the support carriage and therefore the cover system.

La présente invention vise à remédier à tout ou partie de ces inconvénients.The present invention aims to remedy all or part of these disadvantages.

Le problème technique à la base de l'invention consiste donc à fournir un chariot de support pour système de recouvrement de bassin qui soit de structure simple et fiable, tout en assurant un enroulement et un déroulement aisés et fiables d'une couverture de bassin.The technical problem at the base of the invention therefore consists in providing a support carriage for a basin covering system that is of structural simple and reliable, while ensuring an easy and reliable winding and unwinding of a pond cover.

A cet effet, la présente invention concerne un chariot de support pour système de recouvrement de bassin, le chariot de support comprenant :

  • une partie de support déplaçable en translation suivant une direction de déplacement et selon un premier sens de déplacement et un deuxième sens de déplacement opposé au premier sens de déplacement,
  • un tambour d'enroulement configuré pour enrouler et dérouler une couverture de bassin entre une position de recouvrement dans laquelle la couverture de bassin recouvre un bassin et une position de libération dans laquelle la couverture de bassin libère l'accès au bassin, le tambour d'enroulement étant monté mobile en rotation sur la partie de support autour d'un axe de rotation s'étendant transversalement à la direction de déplacement et selon un premier sens de rotation correspondant à un sens de déroulement de la couverture de bassin et un deuxième sens de rotation opposé au premier sens de rotation et correspondant à un sens d'enroulement de la couverture de bassin,

    • une rotation du moteur d'entraînement dans un premier sens de rotation de moteur entraîne un déplacement de l'accouplement à roue libre dans l'état débrayé et entraîne une rotation des roues motrices dans un premier sens de rotation de roue de manière à déplacer la partie de support dans le premier sens de déplacement,
    • une rotation du moteur d'entraînement dans un deuxième sens de rotation de moteur, opposé au premier sens de rotation de moteur, entraîne un déplacement de l'accouplement à roue libre dans l'état embrayé et une rotation du tambour d'enroulement dans le deuxième sens de rotation de manière à déplacer la partie de support dans le deuxième sens de déplacement, et entraîne en outre une rotation des roues motrices dans un deuxième sens de rotation de roue opposé au premier sens de rotation de roue, et
    • un dispositif de levage pourvu de deux organes de roulement configurés pour rouler respectivement sur les deux surfaces de roulement disposées de part et d'autre du bassin, le dispositif de levage étant configuré pour déplacer la partie de support entre une position abaissée dans laquelle les roues motrices sont configurées pour rouler sur les deux surfaces de roulement et les organes de roulement sont configurés pour être situés à distance des deux surfaces de roulement, et une position levée dans laquelle les roues motrices sont configurées pour être situées à distance des deux surfaces de roulement et les organes de roulement sont configurés pour rouler sur les deux surfaces de roulement, le dispositif de levage étant configuré pour déplacer la partie de support dans la position levée lorsque le moteur d'entraînement est entraîné en rotation dans le deuxième sens de rotation.
For this purpose, the present invention relates to a support carriage for a pond cover system, the support carriage comprising:
  • a support part displaceable in translation in a direction of displacement and in a first direction of displacement and a second direction of displacement opposite to the first direction of movement,
  • a winding drum configured to wind and unwind a pool cover between a lap position in which the pool cover overlaps a pool and a release position in which the pool cover releases access to the pool, the pool drum; winding being rotatably mounted on the support portion about an axis of rotation extending transversely to the direction of movement and in a first direction of rotation corresponding to a direction of unwinding of the basin cover and a second direction of rotation opposite to the first direction of rotation and corresponding to a winding direction of the basin cover,
  • two driving wheels configured to roll respectively on two rolling surfaces arranged on either side of the basin, and
  • a drive mechanism having a freewheel coupling connected to the winding drum and a drive motor connected to the freewheel coupling and to the driving wheels, the overrunning clutch being movable between an engaged state in which the freewheel coupling is adapted to transmit a rotational torque to the winding drum and a disengaged state in which the freewheel coupling is unable to transmit a rotational torque to the winding drum, the drive mechanism being configured so that:
    • a rotation of the drive motor in a first direction of motor rotation causes a displacement of the freewheel coupling in the disengaged state and causes a rotation of the drive wheels in a first direction of wheel rotation so as to displace the support part in the first direction of movement,
    • a rotation of the drive motor in a second direction of motor rotation, opposite the first direction of motor rotation, causes the freewheel coupling to move in the engaged state and a rotation of the winding drum in the second direction of rotation so as to move the support part in the second direction of movement, and furthermore causes a rotation of the drive wheels in a second direction of wheel rotation opposite to the first direction of wheel rotation, and
    • a lifting device provided with two rolling members configured for rolling respectively on the two rolling surfaces arranged on either side of the basin, the lifting device being configured to move the support part between a lowered position in which the wheels engines are configured to roll on both tread surfaces and the tread members are configured to be spaced apart from the two tread surfaces, and a raised position in which the driving wheels are configured to be located away from the two tread surfaces and the rolling members are configured to roll on both rolling surfaces, the lifting device being configured to move the support portion into the raised position when the driving motor is rotated in the second direction of rotation.

Par conséquent, lorsque le moteur d'entrainement est entraîné en rotation dans le premier sens de rotation, les roues motrices roulent sur les deux surfaces de roulement et provoquent ainsi un déplacement de la partie de support dans le premier sens de déplacement. Un tel déplacement de la partie de support induit une traction sur la couverture de basse, ce qui provoque une rotation du tambour d'enroulement dans le premier sens de rotation et donc un déroulement de la couverture de bassin.Therefore, when the drive motor is rotated in the first direction of rotation, the drive wheels roll on both rolling surfaces and thereby cause a displacement of the support portion in the first direction of travel. Such a displacement of the support portion induces a pull on the bass cover, which causes a rotation of the winding drum in the first direction of rotation and thus a flow of the pool cover.

Lorsque le moteur d'entrainement est entraîné en rotation dans le deuxième sens de rotation, les roues motrices sont situées à distance des deux surfaces de roulement et tournent librement tandis que le tambour d'enroulement est entraîné en rotation dans le deuxième sens de rotation par l'intermédiaire de l'accouplement à roue libre. Une telle rotation du tambour d'enroulement induit un enroulement de la couverture de bassin autour du tambour d'enroulement et donc un déplacement de la partie de support dans le deuxième sens de déplacement.When the drive motor is rotated in the second direction of rotation, the driving wheels are located at a distance from the two running surfaces and rotate freely while the winding drum is rotated in the second direction of rotation by through the freewheel coupling. Such a rotation of the winding drum induces a winding of the basin cover around the winding drum and thus a displacement of the support part in the second direction of movement.

Une telle configuration du chariot de support permet, lors de l'enroulement de la couverture de bassin, d'éviter tout contact entre les roues motrices et les deux surfaces de roulement disposées de part et d'autre du bassin, et donc d'assurer notamment un enroulement optimal et fiable de la couverture de bassin autour du tambour d'enroulement.Such a configuration of the support carriage makes it possible, during the winding of the pool cover, to avoid any contact between the drive wheels and the two running surfaces arranged on either side of the pool, and thus to ensure in particular an optimal and reliable winding of the pool cover around the winding drum.

However, the basin cover 4 could have a different structure, and for example be made in the form of a deck blade.

Le système de recouvrement 2 comprend en outre un chariot de support 7 s'étendant selon une direction générale d'extension De.The covering system 2 further comprises a support carriage 7 extending in a general extension direction De.

Comme montré plus particulièrement sur la figure 1, le chariot de support 7 comporte une partie de support 8 déplaçable en translation suivant une direction de déplacement Dd et selon un premier sens de déplacement S1 et un deuxième sens de déplacement S2 opposé au premier sens de déplacement S1.

Le chariot de support 7 comporte en outre deux roues motrices 13 montées mobiles en rotation respectivement sur les deux éléments de support 9 autour d'axes de rotation B s'étendant parallèlement à l'axe de rotation A du tambour d'enroulement 11. Avantageusement, chaque roue motrice 13 comporte une bande de roulement, par exemple en matière plastique.The support carriage 7 further comprises two driving wheels 13 rotatably mounted respectively on the two support elements 9 about axes of rotation B extending parallel to the axis of rotation A of the winding drum 11. Advantageously each driving wheel 13 comprises a tread, for example made of plastics material.

Les deux roues motrices 13 sont configurées pour rouler respectivement sur deux surfaces de roulement longitudinales 14 disposées de part et d'autre du bassin 3, et s'étendant plus particulièrement respectivement le long des bords longitudinaux 10 du bassin 3.The two drive wheels 13 are configured to roll respectively on two longitudinal running surfaces 14 disposed on either side of the basin 3, and extending more particularly respectively along the longitudinal edges 10 of the basin 3.

Avantageusement, le chariot de support 7 comporte un arbre d'entraînement 15 sur lequel sont fixées les roues motrices 13. L'arbre d'entraînement 15 s'étend parallèlement au tambour d'enroulement 11 et comprend plus particulièrement deux portions d'extrémité opposées l'une à l'autre et respectivement montées sur les deux éléments de support 9.Advantageously, the support carriage 7 comprises a drive shaft 15 on which are fixed the drive wheels 13. The drive shaft 15 extends parallel to the winding drum 11 and more particularly comprises two opposite end portions. to one another and respectively mounted on the two support elements 9.

Le chariot de support 7 comporte en outre deux éléments de roulement 16 ayant des axes de rotation C s'étendant parallèlement à l'axe de rotation A du tambour d'enroulement 11, et configurés pour rouler respectivement sur les deux surfaces de roulement 14 disposées de part et d'autre du bassin 3. Avantageusement, les éléments de roulement 16 sont décalés par rapport aux roues motrices 13 suivant la direction de déplacement Dd. Une telle disposition des éléments de roulement 16 et des roues motrices 13 assure une grande stabilité au chariot de support 7.The support carriage 7 further comprises two rolling elements 16 having axes of rotation C extending parallel to the axis of rotation A of the winding drum 11, and configured to roll respectively on the two rolling surfaces 14 arranged on either side of the basin 3. Advantageously, the rolling elements 16 are offset relative to the drive wheels 13 in the direction of displacement Dd. Such an arrangement of the rolling elements 16 and the driving wheels 13 ensures a great stability to the support carriage 7.

Le chariot de support 7 comporte de plus un mécanisme d'entraînement 17 configuré pour entraîner en rotation les roues motrices 13 dans deux sens de rotation opposés, et pour entraîner en rotation le tambour d'enroulement 11 dans le deuxième sens de rotation ST2.The support carriage 7 further comprises a drive mechanism 17 configured to drive the driving wheels 13 in rotation in two opposite directions of rotation, and to rotate the winding drum 11 in the second direction of rotation S T 2 .

Le mécanisme d'entraînement 17 comporte plus particulièrement un accouplement à roue libre 18, également nommé roue libre, fixé à l'une des portions d'extrémité du tambour d'enroulement 11 de telle sorte que l'accouplement à roue libre 18 et le tambour d'enroulement 11 s'étendent coaxialement. L'accouplement à roue libre 18 est déplaçable entre un état embrayé dans lequel l'accouplement à roue libre 18 peut transmettre un couple de rotation au tambour d'enroulement 11 et un état débrayé dans lequel l'accouplement à roue libre 18 ne peut pas transmettre un couple de rotation au tambour d'enroulement 11. L'accouplement à roue libre 18 comporte par exemple une partie menante et une partie menée, qui sont coaxiales et qui sont associées de manière à s'accoupler l'une à l'autre et à se désaccoupler l'une de l'autre selon le sens de rotation de la partie menante. La partie menée de l'accouplement à roue libre 18 est avantageusement fixée à la portion d'extrémité respective du tambour d'enroulement 11.The drive mechanism 17 more particularly comprises a freewheel coupling 18, also called a freewheel, attached to one of the end portions of the winding drum 11 so that the freewheel coupling 18 and the winding drum 11 extend coaxially. The freewheel coupling 18 is movable between an engaged state in which the freewheeling coupling 18 can transmit a rotational torque to the winding drum 11 and a disengaged state in which the freewheeling coupling 18 can not transmitting a rotational torque to the winding drum 11. The overrunning clutch 18 includes, for example, a driving portion and a driven portion, which are coaxial and are associated to mate with each other and to disconnect from each other in the direction of rotation of the driving portion. The driven portion of the freewheel coupling 18 is preferably attached to the respective end portion of the winding drum 11.

Le mécanisme d'entraînement 17 comporte en outre un pignon moteur 21 solidaire en rotation de l'arbre de sortie du moteur d'entraînement 19, et un pignon d'entraînement 22 solidaire en rotation des roues motrices 13, et plus particulièrement d'une portion d'extrémité de l'arbre d'entraînement 15 sur lequel sont montées les roues motrices 13. Avantageusement, le pignon d'entraînement 22 et l'arbre d'entraînement 15 s'étendent coaxialement.The drive mechanism 17 further comprises a motor pinion 21 rotatably connected to the output shaft of the drive motor 19, and a drive pinion 22 rotatably connected to the driving wheels 13, and more particularly to a driving pinion. end portion of the drive shaft 15 on which are mounted the drive wheels 13. Advantageously, the drive pinion 22 and the drive shaft 15 extend coaxially.

Le mécanisme d'entraînement 17 comporte de plus un élément de transmission sans fin 23, tel qu'une courroie de transmission, reliant le pignon moteur 21 à la partie menante de l'accouplement à roue libre 18 et au pignon d'entraînement 22. L'élément de transmission 23 est ainsi configuré pour transmettre un mouvement de rotation du moteur d'entraînement 19 à l'accouplement à roue libre 18 et au pignon d'entraînement 22.The drive mechanism 17 further comprises an endless transmission element 23, such as a transmission belt, connecting the drive pinion 21 to the driving portion of the freewheel coupling 18 and to the drive pinion 22. The transmission element 23 is thus configured to transmit a rotational movement of the drive motor 19 to the freewheel coupling 18 and to the drive gear 22.

Le mécanisme d'entraînement 17 est plus particulièrement configuré de telle sorte que :

  • une rotation du moteur d'entraînement 19 dans un premier sens de rotation de moteur SM1 entraîne un déplacement de l'accouplement à roue libre 18 dans l'état débrayé et entraîne une rotation des roues motrices 13 dans un premier sens de rotation de roue SR1,
  • une rotation du moteur d'entraînement 19 dans un deuxième sens de rotation de moteur SM2, opposé au premier sens de rotation de moteur SM1, entraîne d'une part un déplacement de l'accouplement à roue libre 18 dans l'état embrayé et ainsi une rotation du tambour d'enroulement 11 dans le deuxième sens de rotation ST2, et d'autre part une rotation des roues motrices 13 dans un deuxième sens de rotation de roue opposé au premier sens de rotation de roue SR2.
The drive mechanism 17 is more particularly configured such that:
  • a rotation of the drive motor 19 in a first direction of motor rotation S M 1 causes a displacement of the freewheel coupling 18 in the disengaged state and causes a rotation of the drive wheels 13 in a first wheel rotation direction S R 1,
  • a rotation of the drive motor 19 in a second direction of rotation of the motor S M 2, opposite the first direction of motor rotation S M 1, causes on the one hand a displacement of the freewheel coupling 18 in the state engaged and thus a rotation of the winding drum 11 in the second direction of rotation S T 2, and secondly a rotation of the drive wheels 13 in a second direction of wheel rotation opposite to the first direction of wheel rotation S R 2.

Le chariot de support 7 comporte de plus un dispositif de levage 24 pourvu de deux organes de roulement 25 configurés pour rouler respectivement sur les deux surfaces de roulement 14 disposées de part et d'autre du bassin 3. Le dispositif de levage 24 est plus particulièrement configuré pour déplacer la partie de support 8 entre une position abaissée dans laquelle les roues motrices 13 sont configurées pour rouler sur les deux surfaces de roulement 14 et les organes de roulement 25 sont configurés pour être situés à distance des deux surfaces de roulement 14, et une position levée (voir la figure 6) dans laquelle les roues motrices 13 sont configurées pour être situées à distance des deux surfaces de roulement 14 et les organes de roulement 25 sont configurés pour rouler sur les deux surfaces de roulement 14.The support carriage 7 further comprises a lifting device 24 provided with two rolling members 25 configured to roll respectively on the two rolling surfaces 14 disposed on either side of the basin 3. The lifting device 24 is more particularly configured to move the support portion 8 between a lowered position in which the drive wheels 13 are configured to roll on the two rolling surfaces 14 and the rolling members 25 are configured to be located at a distance from the two rolling surfaces 14, and a raised position (see figure 6 ) in which the driving wheels 13 are configured to be located at a distance from the two running surfaces 14 and the rolling members 25 are configured to roll on the two running surfaces 14.

Le dispositif de levage 24 comporte plus particulièrement :

  • deux organes de support 26, tels que des chapes de support, sur lesquels sont montés respectivement les deux organes de roulement 25, chaque organe de support 26 étant monté mobile sur la partie de support 8, et plus particulièrement sur un élément de support 9 respectif, entre une première position correspondant à la position abaissée de la partie de support 8 et une deuxième position correspondant à la position levée de la partie de support 8, et
  • deux actionneurs 27 associés chacun à un organe de support 26 respectif, chaque actionneur 27 étant configuré pour déplacer l'organe de support 26 respectif entre les première et deuxième positions.
The lifting device 24 more particularly comprises:
  • two support members 26, such as support screeds, on which are respectively mounted the two rolling members 25, each support member 26 being mounted to move on the support portion 8, and more particularly on a respective support member 9 between a first position corresponding to the lowered position of the support part 8 and a second position corresponding to the raised position of the support part 8, and
  • two actuators 27 each associated with a respective support member 26, each actuator 27 being configured to move the respective support member 26 between the first and second positions.

Selon le mode de réalisation représenté sur les figures, chaque organe de support 26 est monté pivotant sur la partie de support 8 autour d'un axe de pivotement parallèle à l'axe de rotation du tambour d'enroulement 11, et chaque actionneur 27 est un vérin, par exemple électrique, comportant une première portion fixée à la partie de support 8 et une deuxième portion fixée à l'organe de support 26 respectif.According to the embodiment shown in the figures, each support member 26 is pivotally mounted on the support portion 8 about a pivot axis parallel to the axis of rotation of the winding drum 11, and each actuator 27 is a jack, for example electric, having a first portion attached to the support portion 8 and a second portion attached to the respective support member 26.

Le chariot de support 7 comporte avantageusement une unité de commande 28 configurée pour commander notamment le fonctionnement du moteur d'entraînement 19 et du dispositif de levage 24. L'unité de commande 26 est plus particulièrement configurée pour commander un déplacement de la partie de support 8 dans la position levée lorsque le moteur d'entraînement 19 est entraîné en rotation dans le deuxième sens de rotation SM2, et pour commander un déplacement de la partie de support 8 dans la position abaissée lorsque le moteur d'entraînement 19 est entraîné en rotation dans le premier sens de rotation SM1.The support carriage 7 advantageously comprises a control unit 28 configured to control in particular the operation of the drive motor 19 and the lifting device 24. The control unit 26 is more particularly configured to control a displacement of the support portion 8 in the raised position when the drive motor 19 is rotated in the second direction of rotation S M 2, and to control a displacement of the support portion 8 in the lowered position when the drive motor 19 is driven. in rotation in the first direction of rotation S M 1.

Par conséquent, lorsque le moteur d'entrainement 19 est entraîné en rotation dans le premier sens de rotation SM1, les roues motrices 13 roulent sur les deux surfaces de roulement 14 et provoquent ainsi un déplacement de la partie de support 8 dans le premier sens de déplacement S1. Un tel déplacement de la partie de support 8 induit une traction sur la couverture de basse 4, ce qui provoque une rotation du tambour d'enroulement 11 dans le premier sens de rotation ST1 et donc un déroulement de la couverture de bassin 4.Consequently, when the drive motor 19 is rotated in the first direction of rotation S M 1, the driving wheels 13 roll on the two rolling surfaces 14 and thus cause the support portion 8 to move in the first direction. direction of movement S1. Such a displacement of the support portion 8 induces a pull on the lower cover 4, which causes a rotation of the winding drum 11 in the first direction of rotation S T 1 and thus a flow of the basin cover 4.

Lorsque le moteur d'entrainement 19 est entraîné en rotation dans le deuxième sens de rotation SM2, les roues motrices 13 sont situées à distance des deux surfaces de roulement 14 tandis que le tambour d'enroulement 11 est entraîné en rotation dans le deuxième sens de rotation ST2 par l'intermédiaire de l'accouplement à roue libre 18. Une telle rotation du tambour d'enroulement 11 induit un enroulement de la couverture de bassin 4 autour du tambour d'enroulement 11 et donc un déplacement de la partie de support 8 dans le deuxième sens de déplacement S2.When the drive motor 19 is driven in rotation in the second direction of rotation S M 2, the drive wheels 13 are located at a distance from the two rolling surfaces 14 while the winding drum 11 is rotated in the second direction of rotation S T 2 via the overrunning coupling 18. Such a rotation of the winding drum 11 induces a winding of the pool cover 4 around the winding drum 11 and thus a displacement of the support portion 8 in the second direction of movement S2.

De façon avantageuse, le chariot de support 7 comprend un dispositif d'ajustement 29 configuré pour ajuster la tension de l'élément de transmission sans fin 23. Selon le mode de réalisation représenté sur les figures, le dispositif d'ajustement 29 comprend :

  • an adjustment member 31 configured to exert a pressure on an outer surface of the endless transmission member 23, the adjustment member 31 being translationally movably mounted on one of the support members 9 in a direction d transverse adjustment to the axis of rotation of the winding drum 11 and between a first adjustment position in which the adjustment element 31 is brought closer to the driving pinion 21 and a second adjustment position in which the element adjustment 31 is remote from the driving pinion 21, and
  • a biasing member (not shown in the figures) configured to bias the adjustment member 31 toward the first adjustment position.

Avantageusement, l'élément d'ajustement 31 est en outre monté mobile en rotation par rapport à la partie de support 8 autour d'un axe de rotation s'étendant parallèlement à l'axe de rotation A du tambour d'enroulement 11, et comporte une denture périphérique 32 configurée pour coopérer avec l'élément de transmission sans fin 23.Advantageously, the adjustment element 31 is further mounted rotatably with respect to the support portion 8 about an axis of rotation extending parallel to the axis of rotation A of the winding drum 11, and has a peripheral toothing 32 configured to cooperate with the endless transmission element 23.

Le chariot de support 7 pourrait en outre comporter un ou plusieurs panneaux photovoltaïques 33 configurés pour alimenter électriquement notamment l'unité de commande 28, le moteur d'entraînement 19 et les actionneurs 27. Chaque panneau photovoltaïque 33 peut par exemple être monté sur une face supérieure du capot de protection 12.The support carriage 7 could also comprise one or more photovoltaic panels 33 configured to supply electrical power, in particular to the control unit 28, the drive motor 19 and the actuators 27. Each photovoltaic panel 33 may for example be mounted on one face top of the protective cover 12.

Comme montré sur les figures 10 et 11, le chariot de support 7 pourrait également comporter avantageusement une première brosse de nettoyage 34 disposée sur un bord avant de la partie de support 8 et une deuxième brosse de nettoyage 35 disposée sur un bord arrière de la partie de support 8. La première brosse de nettoyage 34 est plus particulièrement configurée pour nettoyer les bords longitudinaux 10 du bassin 4 lors des déplacements de la partie de support 8 selon le premier sens de déplacement S1, et donc avant la dépose de la couverture de bassin 4 sur les bords longitudinaux 10 du bassin 3. La deuxième brosse de nettoyage 35 est plus particulièrement configurée pour nettoyer la surface supérieure de la couverture de bassin 4 lors des déplacements de la partie de support 8 selon le deuxième sens de déplacement S2, et donc avant l'enroulement de la couverture de bassin 4 autour du tambour d'enroulement 11.
