Description

Domaine techniqueTechnical field

La présente invention concerne un chariot de support pour système de recouvrement de bassin, et un système de recouvrement de bassin comprenant un tel chariot de support.The present invention relates to a support trolley for a pool covering system, and to a pool covering system comprising such a support trolley.

Etat de la techniqueState of the art

Le document FR2244066 divulgue un système de recouvrement d'un bassin, tel qu'une piscine, comprenant :

  • une couverture de bassin configurée pour protéger le bassin contre la pollution de l'eau et les déperditions de chaleur de l'eau, et pour assurer la sécurité des enfants près du bassin, et
  • un chariot de support comportant :
    • une partie de support déplaçable en translation 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 le 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 et un deuxième sens de rotation opposé au premier sens de rotation,
    • deux éléments de roulement configurés pour rouler respectivement sur deux surfaces de roulement disposées de part et d'autre du bassin, et
    • un mécanisme d'entraînement comportant un premier accouplement à roue libre relié au tambour d'enroulement, un deuxième accouplement à roue libre relié aux éléments de roulement, et un moteur d'entraînement relié aux premier et deuxième accouplements à roue libre et aux éléments de roulement par l'intermédiaire d'un élément de transmission sans fin, le premier accouplement à roue libre étant déplaçable entre un état embrayé dans lequel le premier accouplement à roue libre est apte à transmettre un couple de rotation au tambour d'enroulement et un état débrayé dans lequel le premier accouplement à roue libre est inapte à transmettre un couple de rotation au tambour d'enroulement, et le deuxième accouplement à roue libre étant déplaçable entre un état embrayé dans lequel le deuxième accouplement à roue libre est apte à transmettre un couple de rotation aux éléments de roulement et un état débrayé dans lequel le deuxième accouplement à roue libre est inapte à transmettre un couple de rotation aux éléments de roulement.
The document FR2244066 discloses a system for covering a basin, such as a swimming pool, comprising:
  • a pool cover configured to protect the pool from water pollution and heat loss from the water, and to ensure the safety of children near the pool, and
  • a support trolley comprising:
    • a support part movable in translation in a first direction of movement and a second direction of movement opposite to the first direction of movement,
    • a winding drum configured to wind and unwind a pool cover between a covering position in which the pool cover covers the pool and a release position in which the pool cover releases access to the pool, the winding drum being mounted rotatably on the support portion about an axis of rotation extending transversely to the direction of movement and in a first direction of rotation and a second direction of rotation opposite the first direction of rotation,
    • two rolling elements configured to roll respectively on two rolling surfaces arranged on either side of the basin, and
    • a drive mechanism comprising a first overrunning clutch connected to the winding drum, a second overrunning clutch connected to the rolling elements, and a drive motor connected to the first and second overrunning clutches and the rolling elements via an endless transmission element, the first overrunning clutch being movable between an engaged state in which the first overrunning clutch is capable of transmitting a rotational torque to the winding drum and a disengaged state in which the first overrunning clutch is incapable of transmitting a rotational torque to the winding drum, and the second overrunning clutch being movable between an engaged state in which the second overrunning clutch is capable of transmitting a rotational torque to the rolling elements and a disengaged state in which the second overrunning clutch is incapable of transmitting 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 motor rotation direction causes a movement of the first overrunning clutch in the disengaged state and a movement of the second overrunning clutch in the engaged state, and thus causes a rotation of the rolling elements in a first rotation direction so as to move the support part in a direction of unwinding of the pool cover, and
  • a rotation of the drive motor in a second motor rotation direction, opposite to the first motor rotation direction, causes a movement of the first overrunning clutch in the engaged state and a movement of the second overrunning clutch in the disengaged state, and thus causes a rotation of the winding drum in the second rotation direction so as to move the support part in a winding direction of the pool 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, when rolling up the pool cover, the driven part of the second overrunning clutch, which is rotationally secured to the rolling elements, is likely to be driven in rotation, depending on the diameters of the rolling elements and the diameter of the winding drum which changes during the phase of rolling up the pool cover, at a rotational speed which may induce the second overrunning clutch to switch to the engaged state. However, such a switch of the second overrunning clutch to the engaged state when rolling up the pool cover, while the rolling elements are rolling on the rolling surfaces arranged on either side of the pool, is detrimental to the quality of the winding of the pool cover, but also to the reliability of the drive mechanism, since it may induce wear or even breakage of certain elements of the drive mechanism, such as the first and second overrunning clutches and the endless transmission element.

De plus, 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. EP 3 318 700 A1 , EP 3 739 149 A1 et FR 2 908 402 A1 divulguent aussi des chariots de support selon l'état de la technique.In addition, such a support carriage is complex and expensive. Furthermore, such a support carriage has many parts that are susceptible to failure, which adversely affects the reliability of the support carriage and thus of the covering system. EP 3 318 700 A1 , EP 3 739 149 A1 And FR 2 908 402 A1 also disclose support carts according to the state of the art.

  • 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'organe d'accouplement selon la direction de déplacement et dans le deuxième état embrayé et entraîne une rotation de la roue motrice respective dans un sens de fermeture de bassin.
For this purpose, the present invention relates to a support trolley for a pool covering system, the support trolley comprising:
  • a support portion configured to be movable in translation relative to the pelvis in a translation direction, the support part comprising two lateral support frames intended to move respectively along two opposite lateral edges of the basin,
  • a winding drum configured to wind and unwind a pool cover between a covering position in which the pool cover covers a pool and a release position in which the pool cover releases access to the pool, the winding drum comprising two end portions opposite each other and respectively supported by the two lateral support frames, the winding drum being mounted to be rotatably movable relative to the support portion about an axis of rotation extending transversely to the translation direction and in a cover winding direction and a cover unwinding direction opposite the cover winding direction,
  • two drive wheels which are mounted rotatably on the two lateral support frames respectively and which are configured to roll respectively on two rolling surfaces arranged on either side of the basin, and
  • a rotational drive device configured to rotationally drive the winding drum and the two drive wheels, the rotational drive device comprising a drive motor and at least one coupling mechanism arranged at least partly in one of the lateral support frames, the at least one coupling mechanism comprising a coupling member, such as a coupling dog, movable relative to the respective lateral support frame in a direction of movement and between a first engaged state in which the coupling member is configured to rotationally couple the drive motor to the winding drum and is uncoupled from the respective drive wheel, and a second engaged state in which the coupling member is configured to rotationally couple the drive motor to the respective drive wheel and is uncoupled from the winding drum, the at least one coupling mechanism being configured such that:
  • a rotation of the drive motor in a first motor rotation direction causes a movement of the coupling member in the direction of movement and in the first engaged state and causes a rotation of the winding drum in the cover winding direction, and
  • a rotation of the drive motor in a second direction of motor rotation, opposite to the first direction of motor rotation, causes a movement of the coupling member in the direction of movement and in the second engaged state and causes a rotation of the respective drive wheel in a basin closing direction.

Par conséquent, lorsque le moteur d'entrainement est entraîné en rotation dans le premier sens de rotation de moteur, le tambour d'enroulement est entraîné en rotation dans le sens d'enroulement de couverture par l'intermédiaire de l'organe d'accouplement, ce qui induit un enroulement de la couverture de bassin autour du tambour d'enroulement et donc un déplacement de la partie de support dans un sens de déplacement correspondant à une ouverture du bassin.Therefore, when the drive motor is rotated in the first motor rotation direction, the winding drum is rotated in the blanket winding direction via the coupling member, thereby inducing a winding the pool cover around the winding drum and thus moving the support part in a direction of movement corresponding to an opening of the pool.

Lorsque le moteur d'entrainement est entraîné en rotation dans le deuxième sens de rotation de moteur, les roues motrices sont entraînées en rotation dans le sens de fermeture de bassin par l'intermédiaire de l'organe d'accouplement et roulent sur les deux surfaces de roulement disposées de part et d'autre du bassin, ce qui provoque un déplacement de la partie de support dans un sens de déplacement correspondant à une fermeture du bassin. Un tel déplacement de la partie de support induit une traction sur la couverture de bassin, ce qui provoque une rotation du tambour d'enroulement dans le sens de déroulement de couverture et donc un déroulement de la couverture de bassin.When the drive motor is rotated in the second motor rotation direction, the drive wheels are rotated in the pool closing direction via the coupling member and roll on the two rolling surfaces arranged on either side of the pool, which causes the support part to move in a direction of movement corresponding to a pool closing. Such a movement of the support part induces traction on the pool cover, which causes the winding drum to rotate in the cover unwinding direction and thus unwinds the pool cover.

Une telle configuration du dispositif d'entraînement en rotation, et en particulier du mécanisme d'accouplement, assure notamment un enroulement optimal de la couverture de bassin autour du tambour d'enroulement.Such a configuration of the rotation drive device, and in particular of the coupling mechanism, ensures in particular optimum winding of the pool cover around the winding drum.

Description détailléeDetailed description

Les figures 1 à 12 représentent un système de recouvrement de bassin 2 destiné à recouvrir un bassin 3, tel qu'une piscine.THE Figures 1 to 12 represent a basin covering system 2 intended to cover a basin 3, such as a swimming pool.

Le système de recouvrement de bassin 2 comprend une couverture de bassin 4 comportant deux bords transversaux 5 opposés l'un à l'autre et deux bords longitudinaux 6 également opposés l'un à l'autre. L'un des bords transversaux 5 de la couverture de bassin 4 est destiné à être fixé à un bord transversal du bassin 3, par exemple, selon le mode de réalisation représenté sur la figure 1, le bord transversal opposé aux escaliers permettant l'accès au bassin 3.The pool covering system 2 comprises a pool cover 4 having two transverse edges 5 opposite each other and two longitudinal edges 6 also opposite each other. One of the transverse edges 5 of the pool cover 4 is intended to be fixed to a transverse edge of the pool 3, for example, according to the embodiment shown in the figure 1 , the transverse edge opposite the stairs providing access to pool 3.

Selon le mode de réalisation représenté sur les figures, la couverture de bassin 4 comporte une bâche 4.1 qui est souple et qui peut par exemple être réalisée en PVC, et des barres de support 4.2 fixées à la bâche 4.1 et configurées pour reposer sur des bords opposés du bassin 3, et plus particulièrement sur les bords longitudinaux du bassin 3. Chaque barre de support 4.2 peut par exemple être insérée dans un fourreau respectif prévu sur la bâche. Une telle couverture de bassin 4 est également nommée couverture à barres ou bâche à barres. Toutefois, la couverture de bassin 4 pourrait présenter une structure différente, et par exemple être réalisée sous la forme d'un tablier à lames.According to the embodiment shown in the figures, the pool cover 4 comprises a tarpaulin 4.1 which is flexible and which can for example be made of PVC, and support bars 4.2 fixed to the tarpaulin 4.1 and configured to rest on opposite edges of the pool 3, and more particularly on the longitudinal edges of the pool 3. Each support bar 4.2 can for example be inserted into a respective sheath provided on the tarpaulin. Such a pool cover 4 is also called a bar cover or bar tarpaulin. However, the pool cover 4 could have a different structure, and for example be made in the form of a slatted apron.

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

Comme montré plus particulièrement sur la figure 1, le chariot de support 7 comporte une partie de support 8 configurée pour être déplaçable en translation suivant une direction de translation Dt et selon un premier sens de déplacement S1 et un deuxième sens de déplacement S2 opposé au premier sens de déplacement S1. La direction de translation Dt de la partie de support 8 s'étend avantageusement perpendiculairement à la direction générale d'extension De du chariot de support 7 et parallèlement à la direction d'extension du bassin 3.As shown more particularly on the figure 1 , the support carriage 7 comprises a support portion 8 configured to be movable in translation in a translation direction Dt and in a first direction of movement S1 and a second direction of movement S2 opposite the first direction of movement S1. The translation direction Dt of the support portion 8 advantageously extends perpendicular to the general direction of extension De of the support carriage 7 and parallel to the direction of extension of the basin 3.

Comme montré plus particulièrement sur la figure 2, la partie de support 8 comporte deux châssis de support latéraux 9 destinés à se déplacer respectivement le long de deux bords latéraux opposés du bassin, et plus particulièrement le long de deux bords longitudinaux du bassin 3. Afin de renforcer la structure du chariot de support 7, la partie de support 8 pourrait éventuellement comprendre en outre un ou plusieurs éléments de renfort, tel(s) que des poutres de renfort, reliant les deux châssis de support latéraux 9.As shown more particularly on the figure 2 , the support part 8 comprises two lateral support frames 9 intended to move respectively along two opposite lateral edges of the basin, and more particularly along two longitudinal edges of the basin 3. In order to reinforce the structure of the support carriage 7, the support part 8 could optionally further comprise one or more reinforcing elements, such as reinforcing beams, connecting the two lateral support frames 9.

Le chariot de support 7 comporte également un tambour d'enroulement 11 configuré pour enrouler et dérouler la couverture de bassin 4 entre une position de recouvrement dans laquelle la couverture de bassin 4 est déroulée et recouvre la totalité ou sensiblement la totalité du bassin 3, et une position de libération dans laquelle la couverture de bassin 4 est enroulée et libère l'accès au bassin 3. Pour cela, le bord transversal 5 de la couverture de bassin 4, qui est opposé au bord transversal 5 fixé au bassin 3, est fixé au tambour d'enroulement 11.The support carriage 7 also comprises a winding drum 11 configured to wind and unwind the pool cover 4 between a covering position in which the pool cover 4 is unwound and covers all or substantially all of the pool 3, and a release position in which the pool cover 4 is rolled up and releases access to the pool 3. For this, the transverse edge 5 of the pool cover 4, which is opposite the transverse edge 5 fixed to the pool 3, is fixed to the winding drum 11.

Le tambour d'enroulement 11 comprend deux portions d'extrémité opposées l'une à l'autre et respectivement supportées par les deux châssis de support latéraux 9. Le tambour d'enroulement 11 est monté mobile en rotation par rapport à la partie de support 8 autour d'un axe de rotation A (voir la figure 7) s'étendant perpendiculairement à la direction de translation Dt et selon un sens d'enroulement de couverture SE et un sens de déroulement de couverture SD opposé au sens d'enroulement de couverture SE.The winding drum 11 comprises two end portions opposite each other and respectively supported by the two lateral support frames 9. The winding drum 11 is mounted to be movable in rotation relative to the support part 8 about an axis of rotation A (see FIG. figure 7 ) extending perpendicular to the translation direction Dt and in a cover winding direction SE and a cover unwinding direction SD opposite to the cover winding direction SE.

Avantageusement, les éléments de roulement 14 sont décalés par rapport aux roues motrices 13 suivant la direction de translation Dt. Une telle disposition des éléments de roulement 14 et des roues motrices 13 assure une grande stabilité au chariot de support 7.The support carriage 7 further comprises two rolling elements 14, such as casters or rollers, having axes of rotation extending parallel to the axis of rotation A of the winding drum 11, and configured to roll respectively on the two rolling surfaces arranged on either side of the basin 3. Advantageously, the rolling elements 14 are offset relative to the drive wheels 13 in the translation direction Dt. Such an arrangement of the rolling elements 14 and the drive wheels 13 ensures great stability for the support carriage 7.

Le chariot de support 7 comporte également un dispositif d'entraînement en rotation configuré pour entraîner en rotation le tambour d'enroulement 11 dans le sens d'enroulement de couverture SE et pour entraîner en rotation les deux roues motrices 13 dans un sens de fermeture de bassin.The support carriage 7 also comprises a rotation drive device configured to rotate the winding drum 11 in the cover winding direction SE and to rotate the two drive wheels 13 in a basin closing direction.

De façon avantageuse, la première roue dentée 19 s'étend coaxialement avec le tambour d'enroulement 11, et la deuxième roue dentée 21 s'étend coaxialement avec la roue motrice 13 respective.Each coupling mechanism 17 further comprises a first gear wheel 19 which is rotationally fixed to the winding drum 11, and a second gear wheel 21 which is rotationally fixed to the respective drive wheel 13. Advantageously, the first gear wheel 19 extends coaxially with the winding drum 11, and the second gear wheel 21 extends coaxially with the respective drive wheel 13.

Les première et deuxième roues dentées 19, 21 de chaque mécanisme d'accouplement 17 s'étendent respectivement dans deux plans d'extension respectifs qui sont sensiblement parallèles et qui sont décalés l'un par rapport à l'autre selon un axe longitudinal central de l'arbre d'entraînement 16.The first and second gear wheels 19, 21 of each coupling mechanism 17 extend respectively in two respective extension planes which are substantially parallel and which are offset from each other along a central longitudinal axis of the drive shaft 16.

Chaque organe d'accouplement 18 est plus particulièrement déplaçable par rapport au châssis de support latéral 9 respectif selon une direction de déplacement Dd qui est parallèle à l'axe longitudinal central de l'arbre d'entraînement 16 et entre un premier état embrayé (voir les figures 5, 8 et 10) dans lequel l'organe d'accouplement 18 s'étend dans le plan d'extension de la première roue dentée 19 respective et la denture périphérique de la partie d'accouplement 18.2 respective est couplée en rotation à la première roue dentée 19 respective, et un deuxième état embrayé (voir les figures 6, 9 et 11) dans lequel l'organe d'accouplement 18 s'étend dans le plan d'extension de la deuxième roue dentée 21 respective et la denture périphérique de la partie d'accouplement 18.2 respective est couplée en rotation à la deuxième roue dentée 21 respective.Each coupling member 18 is more particularly movable relative to the respective lateral support frame 9 in a direction of movement Dd which is parallel to the central longitudinal axis of the drive shaft 16 and between a first engaged state (see figures 5 , 8 And 10 ) in which the coupling member 18 extends in the extension plane of the respective first gear wheel 19 and the peripheral toothing of the respective coupling part 18.2 is rotatably coupled to the respective first gear wheel 19, and a second engaged state (see the figures 6 , 9 And 11 ) in which the coupling member 18 extends in the extension plane of the respective second gear wheel 21 and the peripheral toothing of the respective coupling part 18.2 is rotatably coupled to the respective second gear wheel 21.

Ainsi, les organes d'accouplement 18 sont configurés pour accoupler en rotation l'arbre d'entraînement 16 au tambour d'enroulement 11 et pour désaccoupler l'arbre d'entraînement 16 des roues motrices 13 lorsque les organes d'accouplement 18 occupent le premier état embrayé, et sont configurés pour accoupler en rotation l'arbre d'entraînement 16 aux roues motrices 13 et désaccoupler l'arbre d'entraînement 16 du tambour d'enroulement 11 lorsque les organes d'accouplement 18 occupent le deuxième état embrayé.Thus, the coupling members 18 are configured to rotatably couple the drive shaft 16 to the winding drum 11 and to uncouple the drive shaft 16 from the drive wheels 13 when the coupling members 18 occupy the first engaged state, and are configured to rotatably couple the drive shaft 16 to the drive wheels 13 and uncouple the drive shaft 16 from the winding drum 11 when the coupling members 18 occupy the second engaged state.

Selon le mode de réalisation représenté sur les figure, la partie de montage 18.1 de chaque organe d'accouplement 18 comporte une paire de rainures de liaison 22 qui s'étendent chacune hélicoïdalement autour de l'axe longitudinal central de l'arbre d'entraînement 16 et dans chacune desquelles est monté coulissant un ergot de liaison 23 respectif prévu sur la portion d'extrémité respective de l'arbre d'entraînement 16. Chaque rainure de liaison 22 peut par exemple être traversante, et ainsi former une fente de liaison, et chaque ergot de liaison 23 peut par exemple s'étendre radialement par rapport à l'axe longitudinal central de l'arbre d'entraînement 16. De façon avantageuse, les deux ergots de liaison prévus sur chaque portion d'extrémité de l'arbre d'entraînement 16 sont diamétralement opposés.According to the embodiment shown in the figures, the mounting portion 18.1 of each coupling member 18 comprises a pair of connecting grooves 22 which each extend helically around the central longitudinal axis of the drive shaft 16 and in each of which is slidably mounted a respective connecting lug 23 provided on the respective end portion of the drive shaft 16. Each connecting groove 22 may for example be through, and thus form a connecting slot, and each connecting lug 23 may for example extend radially relative to the central longitudinal axis of the drive shaft 16. Advantageously, the two connecting lugs provided on each end portion of the drive shaft 16 are diametrically opposed.

Comme montré sur les figures 10 et 11, chaque rainure de liaison 22 comporte une première surface de came 22.1 configurée pour coopérer avec l'ergot de liaison 23 respectif lorsque l'arbre d'entraînement 16 est entraîné en rotation dans un premier sens de rotation, et une deuxième surface de came 22.2 configurée pour coopérer avec l'ergot de liaison 23 respectif lorsque l'arbre d'entraînement 16 est entraîné en rotation dans un deuxième sens de rotation. Lorsque l'arbre d'entraînement 16 est entraîné en rotation dans le premier sens de rotation et que les organes d'accouplement 18 occupent le deuxième état embrayé (voir la figure 11), chaque ergot de liaison 23 glisse sur la première surface de came 22.1 respective, et, puisque la partie d'accouplement 18.2 respective est couplée en rotation avec la deuxième roue dentée 21 respective, l'organe d'accouplement 18 respectif est déplacé en translation selon la direction de déplacement Dd jusqu'à atteindre le premier état embrayé qui correspond à une position dans laquelle ledit ergot de liaison 23 est en butée contre une première extrémité de la rainure de liaison 22 respective (voir la figure 10). Lorsque l'arbre d'entraînement 16 est entraîné en rotation dans le deuxième sens de rotation et que les organes d'accouplement 18 occupent le premier état embrayé (voir la figure 10), chaque ergot de liaison 23 glisse sur la deuxième surface de came 22.2 respective, et, puisque la partie d'accouplement 18.2 respective est couplée en rotation avec la première roue dentée 19 respective, l'organe d'accouplement 18 respectif est déplacé en translation selon la direction de déplacement Dd jusqu'à atteindre le deuxième état embrayé qui correspond à une position dans laquelle ledit ergot de liaison 23 est en butée contre une deuxième extrémité de la rainure de liaison 22 respective (voir la figure 11)As shown on the Figures 10 and 11 , each connecting groove 22 has a first cam surface 22.1 configured to cooperate with the respective connecting lug 23 when the drive shaft 16 is rotated in a first direction of rotation, and a second cam surface 22.2 configured to cooperate with the respective connecting lug 23 when the drive shaft 16 is rotated in a second direction of rotation. When the drive shaft 16 is rotated in the first direction of rotation and the coupling members 18 occupy the second engaged state (see FIG. figure 11 ), each connecting lug 23 slides on the respective first cam surface 22.1, and, since the respective coupling part 18.2 is rotatably coupled with the respective second gear wheel 21, the respective coupling member 18 is moved in translation in the direction of movement Dd until reaching the first engaged state which corresponds to a position in which said connecting lug 23 abuts against a first end of the respective connecting groove 22 (see FIG. figure 10 ). When the drive shaft 16 is rotated in the second direction of rotation and the coupling members 18 occupy the first engaged state (see figure 10 ), each connecting lug 23 slides on the respective second cam surface 22.2, and, since the respective coupling part 18.2 is rotatably coupled with the respective first gear wheel 19, the respective coupling member 18 is moved in translation in the direction of movement Dd until reaching the second engaged state which corresponds to a position in which said connecting lug 23 abuts against a second end of the respective connecting groove 22 (see FIG. figure 11 )

Selon le mode de réalisation représenté sur les figures, chaque mécanisme d'accouplement 17 comporte une roue dentée intermédiaire 24 montée mobile en rotation sur le châssis de support latéral 9 respectif et configurée pour coupler en rotation l'organe d'accouplement 18 avec la première roue dentée 19 respective lorsque l'organe d'accouplement 18 occupe le premier état embrayé.According to the embodiment shown in the figures, each coupling mechanism 17 comprises an intermediate toothed wheel 24 mounted rotatably on the respective lateral support frame 9 and configured to rotatably couple the coupling member 18 with the respective first toothed wheel 19 when the coupling member 18 occupies the first engaged state.

Chaque mécanisme d'accouplement 17 est plus particulièrement configuré de telle sorte que :

  • une rotation du moteur d'entraînement 15 dans un premier sens de rotation de moteur entraîne un déplacement de l'organe d'accouplement 18 selon la direction de déplacement Dd et dans le premier état embrayé et entraîne une rotation du tambour d'enroulement 11 dans le sens d'enroulement de couverture SE, et
  • une rotation du moteur d'entraînement 15 dans un deuxième sens de rotation de moteur, opposé au premier sens de rotation de moteur, entraîne un déplacement de l'organe d'accouplement 18 selon la direction de déplacement Dd et dans le deuxième état embrayé et entraîne une rotation de la roue motrice 13 respective dans un sens de fermeture de bassin.
Each coupling mechanism 17 is more particularly configured such that:
  • a rotation of the drive motor 15 in a first motor rotation direction causes a movement of the coupling member 18 in the direction of movement Dd and in the first engaged state and causes a rotation of the winding drum 11 in the cover winding direction SE, and
  • a rotation of the drive motor 15 in a second motor rotation direction, opposite to the first motor rotation direction, causes a movement of the coupling member 18 in the direction of movement Dd and in the second engaged state and causes a rotation of the respective drive wheel 13 in a basin closing direction.

Par conséquent, lorsque le moteur d'entrainement 19 est entraîné en rotation dans le premier sens de rotation de moteur, le tambour d'enroulement 11 est entraîné en rotation dans le sens d'enroulement de couverture SE par l'intermédiaire de l'organe d'accouplement 18, ce qui 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.Therefore, when the drive motor 19 is rotated in the first motor rotation direction, the winding drum 11 is rotated in the second direction. cover winding drive SE via the coupling member 18, which induces a winding of the pool cover 4 around the winding drum 11 and therefore a movement of the support part 8 in the second direction of movement S2.

Lorsque le moteur d'entrainement 19 est entraîné en rotation dans le deuxième sens de rotation de moteur, les roues motrices 13 sont entraînées en rotation dans le sens de fermeture de bassin par l'intermédiaire de l'organe d'accouplement 18 et roulent sur les deux surfaces de roulement disposées de part et d'autre du bassin 3, ce qui provoque 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 bassin 4, ce qui provoque une rotation du tambour d'enroulement 11 dans le sens de déroulement de couverture SD et donc un déroulement de la couverture de bassin 4.When the drive motor 19 is rotated in the second motor rotation direction, the drive wheels 13 are rotated in the pool closing direction by means of the coupling member 18 and roll on the two rolling surfaces arranged on either side of the pool 3, which causes a displacement of the support part 8 in the first direction of movement S1. Such a displacement of the support part 8 induces a traction on the pool cover 4, which causes a rotation of the winding drum 11 in the cover unwinding direction SD and thus an unwinding of the pool cover 4.

Le chariot de support 7 comporte en outre une unité de commande configurée pour commander notamment le fonctionnement du moteur d'entraînement 15, et peut également comporter un ou plusieurs panneaux photovoltaïques configurés pour alimenter électriquement notamment l'unité de commande et le moteur d'entraînement 15. Chaque panneau photovoltaïque peut par exemple être monté sur une face supérieure du capot de protection 12.The support carriage 7 further comprises a control unit configured to control in particular the operation of the drive motor 15, and may also comprise one or more photovoltaic panels configured to electrically supply in particular the control unit and the drive motor 15. Each photovoltaic panel may for example be mounted on an upper face of the protective cover 12.

Selon le mode de réalisation représenté sur les figures, le chariot de support 7 comporte en outre un dispositif anti-balourd 31 configuré pour exercer un couple résistif, directement ou indirectement, sur le tambour d'enroulement 11, de telle sorte que, lorsqu'une barre de support 4.2 quitte le tambour d'enroulement 11 lors du déroulement de la couverture de bassin 4, la masse de ladite barre de support 4.2 n'entraîne pas une accélération de la rotation du tambour d'enroulement 11 et donc un impact bruyant de ladite barre de support 4.2 contre le bassin 3.According to the embodiment shown in the figures, the support carriage 7 further comprises an anti-imbalance device 31 configured to exert a resistive torque, directly or indirectly, on the winding drum 11, such that, when a support bar 4.2 leaves the winding drum 11 during the unwinding of the pool cover 4, the mass of said support bar 4.2 does not cause an acceleration of the rotation of the winding drum 11 and therefore a noisy impact of said support bar 4.2 against the pool 3.

De façon avantageuse, le dispositif anti-balourd 31 comporte un galet de freinage 32 qui s'étend sensiblement coaxialement avec le tambour d'enroulement 11 et qui est solidaire en rotation du tambour d'enroulement 11, une courroie de friction 33 configurée pour coopérer par friction avec une paroi périphérique externe du galet de freinage 32 et un dispositif de mise en tension 34 configuré pour tendre la courroie de friction 33. Le dispositif de mise en tension 34 peut par exemple comporte un ressort de traction 35 configuré pour exercer un effort de traction sur la courroie de friction 33 qui est orienté sensiblement radialement par rapport à l'axe de rotation A.Advantageously, the anti-imbalance device 31 comprises a braking roller 32 which extends substantially coaxially with the winding drum 11 and which is integral in rotation with the winding drum 11, a friction belt 33 configured to cooperate by friction with an external peripheral wall of the braking roller 32 and a tensioning device 34 configured to tension the friction belt 33. The tensioning device 34 may for example comprise a tension spring 35 configured to exert a tensile force on the friction belt 33 which is oriented substantially radially relative to the axis of rotation A.

Selon un mode de réalisation de l'invention non représenté sur les figures, le dispositif d'entraînement en rotation pourrait comporter deux arbres d'entraînement 16, chaque organe d'accouplement 18 étant alors relié mécaniquement à une portion d'extrémité d'un arbre d'entraînement 16 respectif.According to an embodiment of the invention not shown in the figures, the rotation drive device could comprise two drive shafts 16, each coupling member 18 then being mechanically connected to an end portion of a respective drive shaft 16.

Selon un mode de réalisation de l'invention non représenté sur les figures, le dispositif d'entraînement en rotation pourrait comporter deux moteurs d'entraînement 15, chaque arbre d'entraînement 16 étant alors couplé en rotation à un moteur d'entraînement 15 respectif.According to an embodiment of the invention not shown in the figures, the rotation drive device could comprise two drive motors 15, each drive shaft 16 then being coupled in rotation to a respective drive motor 15.

Comme il va de soi, l'invention ne se limite pas aux seuls modes de réalisation de ce chariot de support 7 et de ce système de recouvrement de bassin 2, décrits ci-dessus à titre d'exemples, elle en embrasse au contraire toutes les variantes de réalisation, selon les revendications attachées.It goes without saying that the invention is not limited to the embodiments of this support carriage 7 and this basin covering system 2, described above as examples; on the contrary, it embraces all the variant embodiments thereof, according to the attached claims.
