DESCRIPTION DETAILLEEDETAILED DESCRIPTION

La présente invention permet de recouvrir automatiquement toute surface plane, en l'espèce un sol 200, par une bâche 210 rectangulaire. La forme de la surface plane peut être quelconque tant qu'elle s'inscrit dans le rectangle de la bâche 210.The present invention makes it possible to automatically cover any flat surface, in this case a floor 200, with a rectangular tarpaulin 210. The shape of the flat surface can be any as long as it fits into the rectangle of the tarpaulin 210.

Par concision, seul le cas où la surface plane est celle d'un bassin, et en particulier d'une piscine, est décrit ici. La piscine peut présenter toute forme.For brevity, only the case where the flat surface is that of a basin, and in particular a swimming pool, is described here. The swimming pool can have any shape.

Le principe de l'invention consiste à enrouler ou dérouler automatiquement une bâche 210 rectangulaire sur la surface plane, de sorte à recouvrir celle-ci par la bâche 210, typiquement par l'intermédiaire d'une télécommande.The principle of the invention consists in automatically winding or unrolling a rectangular tarpaulin 210 on the flat surface, so as to cover the latter with the tarpaulin 210, typically by means of a remote control.

La présente invention comprend un enrouleur 10 automatique de bâche 210 et peut comprendre en outre la bâche 210 correspondant audit enrouleur 10 automatique, ces deux éléments étant décrits ci-après.The present invention comprises an automatic tarpaulin reel 210 and may further comprise the tarpaulin 210 corresponding to said automatic reel 10, these two elements being described below.

Enrouleur automatiqueAutomatic rewinder

L'enrouleur 10 automatique, ci-après « enrouleur » par concision, comprend un tube d'enroulement 20 monté à rotation entre deux blocs mobiles en translation.The automatic winder 10, hereinafter "winder" for brevity, comprises a winding tube 20 rotatably mounted between two blocks movable in translation.

Chaque bloc mobile comprend un capot fermé par un ensemble de vis. Le bloc moteur 60 comprend un capot 70 et le bloc suiveur 65 comprend un capot 170.Each movable block comprises a cover closed by a set of screws. The engine block 60 includes a cowl 70 and the follower block 65 includes a cowl 170.

Le capot protège des éléments extérieurs (pluie, neige, projections d'eau, etc.). Le dévissage des vis permet d'accéder aux éléments du bloc mobile, pour sa configuration initiale ou sa maintenance.The hood protects from external elements (rain, snow, splashing water, etc.). Unscrewing the screws allows access to the elements of the mobile unit, for its initial configuration or maintenance.

Chaque bloc mobile en translation comprend un ensemble d'au moins une roue motrice et de préférence un ensemble d'au moins une roue suiveuse (non motrice).Each block movable in translation comprises a set of at least one driving wheel and preferably a set of at least one following wheel (non-driving).

Les axes des roues motrices et des roues suiveuses sont parallèles et de préférence sont distincts, c'est à dire non confondus. En l'espèce, on prévoit par bloc mobile une roue motrice 40 et une roue suiveuse 50. La roue motrice 40 est entraînée par un moteur 80, La roue motrice et la roue suiveuse ont des axes de rotation parallèles mais non confondus, de sorte que l'une des roues motrice 40 ou suiveuse 50 est une roue avant et l'autre est une roue arrière.The axes of the driving wheels and of the following wheels are parallel and preferably are distinct, that is to say not coincident. In this case, a driving wheel 40 and a follower wheel 50 are provided per movable block. The driving wheel 40 is driven by a motor 80, the driving wheel and the follower wheel have parallel axes of rotation but not coincident, so that one of the driving 40 or follower wheels 50 is a front wheel and the other is a rear wheel.

Avantageusement, l'enrouleur 10 ne comprend qu'un unique moteur 80, en l'espèce un motoréducteur, permettant d'entraîner la roue d'entraînement de chaque bloc mobile simultanément et à la même vitesse. L'une des roues d'entraînement est entraînée directement et l'autre roue d'entraînement est entraînée indirectement, c'est-à-dire via un arbre de transmission 30 reliant les deux blocs mobiles en translation.Advantageously, the reel 10 comprises only a single motor 80, in this case a geared motor, making it possible to drive the drive wheel of each mobile unit simultaneously and at the same speed. One of the drive wheels is driven directly and the other drive wheel is driven indirectly, that is to say via a transmission shaft 30 connecting the two blocks movable in translation.

Le bloc mobile comprenant le moteur 80 est appelé « bloc moteur » 60 et le bloc mobile ne comprenant pas le moteur 80 est appelé « bloc suiveur » 65.The movable block comprising the motor 80 is called "motor block" 60 and the movable block not comprising the motor 80 is called "follower block" 65.

Chaque bloc mobile comprend une roue d'entraînement respective, l'enrouleur 10 peut se déplacer selon ligne droite puisque les deux roues d'entraînement sont entraînées à la même vitesse de rotation.Each movable block comprises a respective drive wheel, the reel 10 can move in a straight line since the two drive wheels are driven at the same rotational speed.

De préférence, on prévoit que les roues d'entraînement soient toutes les deux soit les roues avant, soit les roues arrière. En l'espèce, les roues d'entraînement sont les roues avant.Preferably, provision is made for the drive wheels to both be either the front wheels or the rear wheels. In this case, the drive wheels are the front wheels.

Le moteur 80 est alimenté en énergie électrique par un ensemble d'au moins une batterie 190 électrique, en l'espèce rechargeable grâce à une prise de recharge électrique 180, de préférence répondant à la norme de l'indice de protection IP65, 2 fils conducteurs et un détrompeur (non illustrés). La batterie 190 peut être rechargée sur secteur ou grâce un circuit électrique comprenant un ensemble d'au moins un panneau photovoltaïque.The motor 80 is supplied with electrical energy by a set of at least one electric battery 190, in this case rechargeable thanks to an electrical recharging socket 180, preferably meeting the standard of protection index IP65, 2 wires. conductors and a polarizer (not shown). The battery 190 can be recharged from the mains or by means of an electrical circuit comprising an assembly of at least one photovoltaic panel.

Le moteur 80 est piloté grâce à une carte électronique 220.The motor 80 is controlled by an electronic card 220.

Le moteur 80 entraîne la rotation avant ou la rotation arrière des roues motrices, permettant à l'enrouleur 10 d'avancer ou de reculer en ligne droite. Le moteur 80 entraîne également la rotation du tube d'enroulement 20, permettant d'enrouler ou de dérouler la bâche 210 comme décrit ultérieurement.Motor 80 drives forward or reverse rotation of the drive wheels, allowing reel 10 to move forward or backward in a straight line. The motor 80 also drives the rotation of the winding tube 20, making it possible to wind up or unwind the tarpaulin 210 as described later.

Le moteur 80 entraîne une pluralité de pignons et de chaînes de transmission.Motor 80 drives a plurality of transmission sprockets and chains.

En l'espèce, dans le bloc moteur 60, le moteur 80 entraîne en rotation un premier pignon 100, qui est relié à un deuxième pignon 101 par une première chaîne de transmission 110. Le deuxième pignon 101 est solidaire en rotation de l'arbre de transmission 30.In this case, in the engine block 60, the motor 80 drives in rotation a first pinion 100, which is connected to a second pinion 101 by a first transmission chain 110. The second pinion 101 is integral in rotation with the shaft. transmission 30.

Un troisième pignon 102 est coaxial avec le deuxième pignon 101 et solidaire en rotation de celui-ci. Un quatrième pignon 103 est coaxial avec le moyeu de la roue motrice et solidaire en rotation de celle-ci. Une deuxième chaîne de transmission 111 relie le troisième pignon 102 et le quatrième pignon 103.A third pinion 102 is coaxial with the second pinion 101 and integral in rotation with the latter. A fourth pinion 103 is coaxial with the hub of the drive wheel and integral in rotation with the latter. A second transmission chain 111 connects the third sprocket 102 and the fourth sprocket 103.

Ainsi la rotation du moteur 80 entraîne en rotation d'une part l'arbre de transmission 30 et d'autre part la roue motrice.Thus, the rotation of the motor 80 drives in rotation on the one hand the transmission shaft 30 and on the other hand the drive wheel.

Un cinquième pignon 104 est également coaxial avec le deuxième pignon 101. Il est solidaire en rotation du tube d'enroulement et entraîné en rotation par une troisième chaîne de transmission 112 le reliant au moteur 80 via le premier pignon 100. Ainsi la rotation du moteur 80 entraîne également la rotation du tube d'enroulement.A fifth pinion 104 is also coaxial with the second pinion 101. It is integral in rotation with the winding tube and driven in rotation by a third transmission chain 112 connecting it to the motor 80 via the first pinion 100. Thus the rotation of the motor 80 also drives the rotation of the winding tube.

On prévoit que la vitesse de rotation du tube d'enroulement est différente de la vitesse de rotation des roues motrices, ce qui permet de maintenir la bâche 210 en tension à l'enroulement comme au déroulement.Provision is made for the speed of rotation of the winding tube to be different from the speed of rotation of the drive wheels, which makes it possible to keep the tarpaulin 210 in tension during winding as well as during unwinding.

On prévoit une première paire de composants tribologiques rotatifs 130, 140 pour la rotation et le maintien du tube d'enroulement, une deuxième paire de composants tribologiques rotatifs 150, 160 pour la rotation et le maintien de l'arbre de transmission 30 dans le bloc moteur 60. Par exemple, les composants tribologiques rotatifs sont des roulements à billes ou à rouleaux, des paliers ou des bagues.A first pair of rotary tribological components 130, 140 are provided for the rotation and maintenance of the winding tube, a second pair of rotary tribological components 150, 160 for the rotation and maintenance of the transmission shaft 30 in the block. motor 60. For example, the rotary tribological components are ball or roller bearings, bearings or rings.

De préférence, on prévoit que la roue suiveuse, opposée à la roue motrice, est montée sur palier, ou rotule 270, ce qui permet d'orienter la roue suiveuse pour compenser une éventuelle dérive.Preferably, provision is made for the follower wheel, opposite the driving wheel, to be mounted on a bearing, or ball joint 270, which makes it possible to orient the follower wheel to compensate for any drift.

Dans le bloc suiveur 65, l'arbre de transmission 30 entraîne en rotation un sixième pignon 105, relié par une quatrième chaîne de transmission 113 à un septième pignon 106, coaxial avec la roue motrice du bloc suiveur 65.In the follower block 65, the transmission shaft 30 drives in rotation a sixth pinion 105, connected by a fourth transmission chain 113 to a seventh pinion 106, coaxial with the driving wheel of the follower block 65.

De préférence, de même que pour le bloc moteur 60, on prévoit que la roue suiveuse, opposée à la roue motrice, est montée sur palier, ou rotule, ce qui permet d'orienter la roue suiveuse pour compenser une éventuelle dérive.Preferably, as for the engine block 60, provision is made for the follower wheel, opposite the driving wheel, to be mounted on a bearing, or ball joint, which makes it possible to orient the follower wheel to compensate for any drift.

La roue motrice du bloc moteur 60 et la roue motrice du bloc suiveur 65 tournent de manière synchrone et à la même vitesse. Par exemple, le septième pignon 106 et le quatrième pignon 103 sont identiques.The driving wheel of the motor block 60 and the driving wheel of the follower block 65 rotate synchronously and at the same speed. For example, the seventh pinion 106 and the fourth pinion 103 are identical.

De manière identique au bloc moteur 60, on prévoit une première paire de composants tribologiques rotatifs 130, 140 pour la rotation et le maintien du tube d'enroulement, une deuxième paire de composants tribologiques rotatifs 150, 160 pour la rotation et le maintien de l'arbre de transmission 30 dans le bloc suiveur 65.Similarly to the engine block 60, there is provided a first pair of rotary tribological components 130, 140 for the rotation and maintenance of the winding tube, a second pair of rotary tribological components 150, 160 for the rotation and maintenance of the winding tube. 'transmission shaft 30 in the follower block 65.

Chaque bloc comprend une rampe de guidage 90, disposée sur le flanc intérieur, configurée pour faire glisser la dernière barres 230 d'une bâche 210 à barres vers le sol 200 lors du déroulement de la bâche 210.Each block comprises a guide ramp 90, arranged on the inner side, configured to slide the last bar 230 of a tarpaulin 210 with bars towards the ground 200 during the unwinding of the tarpaulin 210.

Arbre de transmission 30Drive shaft 30

L'arbre de transmission 30 est de préférence coaxial avec le tube d'enroulement 20, sur lequel la bâche 210 peut s'enrouler, et disposé à l'intérieur de celui-ci.The transmission shaft 30 is preferably coaxial with the winding tube 20, on which the tarpaulin 210 can be wound, and arranged inside the latter.

L'arbre de transmission 30 est monté sur une roue libre 71 qui débraye à l'enroulement de la bâche 210 sur le tube d'enroulement 20. Ainsi à l'enroulement, c'est la rotation du tube d'enroulement 20 qui entraîne la translation de l'enrouleur 10.The transmission shaft 30 is mounted on a freewheel 71 which disengages when winding the cover 210 on the winding tube 20. Thus when winding, it is the rotation of the winding tube 20 which drives the translation of the reel 10.

Il existe un rapport de réduction entre les vitesses de rotation de l'arbre de transmission 30 et du tube d'enroulement 20, de sorte que la vitesse de rotation du tube d'enroulement 20 est de préférence inférieure à la vitesse de rotation de l'arbre de transmission 30.There is a reduction ratio between the rotational speeds of the transmission shaft 30 and the winding tube 20, so that the rotational speed of the winding tube 20 is preferably lower than the rotational speed of the winding tube 20. 'drive shaft 30.

Tube d'enroulement 20Winding tube 20

Le tube d'enroulement 20 présente un axe d'allongement parallèle à l'axe de rotation des roues motrices, perpendiculaire au mouvement de translation de l'enrouleur 10.The winding tube 20 has an axis of elongation parallel to the axis of rotation of the drive wheels, perpendicular to the translational movement of the reel 10.

Comme l'arbre de transmission 30, le tube d'enroulement 20 est monté sur une roue libre 72, mais qui débraye dans le sens opposé de la roue libre 71 de l'arbre de transmission 30. Ainsi lorsque l'enrouleur 10 avance, c'est à dire au déroulement, le moteur 80 n'entraîne pas directement en rotation le tube d'enroulement 20, ce qui permet de maintenir la bâche 210 en tension.Like the transmission shaft 30, the winding tube 20 is mounted on a freewheel 72, but which disengages in the opposite direction from the freewheel 71 of the transmission shaft 30. Thus when the reel 10 advances, That is to say during unwinding, the motor 80 does not directly drive the winding tube 20 in rotation, which makes it possible to keep the tarpaulin 210 in tension.

Bâche 210Tarpaulin 210

La bâche 210 selon l'invention est une bâche 210 présentant une forme rectangulaire. En l'espèce, il s'agit d'une bâche 210 à barres 230. Les barres 230 sont parallèles entre elles et perpendiculaires au sens de déplacement de l'enrouleur 10. La longueur des barres 230 est supérieure à celle de la largeur de la piscine que la bâche 210 doit recouvrir.The tarpaulin 210 according to the invention is a tarpaulin 210 having a rectangular shape. In this case, it is a tarpaulin 210 with bars 230. The bars 230 are mutually parallel and perpendicular to the direction of movement of the reel 10. The length of the bars 230 is greater than that of the width of the swimming pool that the cover 210 must cover.

On peut prévoir une bâche 210 à barres 230 classique, c'est à dire avec des barres 230 qui présentent une section circulaire, et qui sont solidaires de la bâche 210, par exemple par rivetage ou par des jeux de sangles. Cependant de telles barres 230 sont compliquées à désolidariser de la bâche 210.It is possible to provide a tarpaulin 210 with conventional bars 230, ie with bars 230 which have a circular section, and which are integral with the tarpaulin 210, for example by riveting or by sets of straps. However, such bars 230 are complicated to separate from the tarpaulin 210.

Avantageusement, on prévoit donc que les barres 230 sont solidaires de la bâche 210 par un ensemble de joncs 240, eux-mêmes solidaires de la bâche 210, par exemple par collage ou par couture, et en l'espèce par soudage de ceux-ci à la bâche 210 par hautes fréquences. Ainsi, quand la bâche 210 est enroulée, les barres 230 restent solidaires de la bâche 210.Advantageously, therefore, provision is made for the bars 230 to be secured to the cover 210 by a set of rods 240, themselves secured to the cover 210, for example by gluing or by stitching, and in this case by welding them. to the covering 210 by high frequencies. Thus, when the tarpaulin 210 is rolled up, the bars 230 remain integral with the tarpaulin 210.

Par exemple, les joncs 240 sont en matériau à base de caoutchouc, solidaire d'une base en tissu comprenant un matériau à base de plastique, en l'espèce du PVC. Ainsi, le PVC du tissu est soudable au PVC de la bâche 210 par hautes fréquences. On peut aussi remplacer la base en tissu par un morceau de bâche 210.For example, the rods 240 are made of a rubber-based material, integral with a fabric base comprising a plastic-based material, in this case PVC. Thus, the PVC of the fabric can be welded to the PVC of the tarpaulin 210 at high frequencies. You can also replace the fabric base with a piece of tarpaulin 210.

De préférence, on prévoit un couple de joncs 240 par barres 230. La largeur de chaque jonc 240 est inférieure ou égale à la largeur de la bâche 210, et de préférence strictement inférieure à la largeur de la bâche 210, ce qui améliore étanchéité de la bâche 210 sur les marges de la piscine. On prévoit en l'espèce que la largeur de chaque jonc 240 est égale à la largeur de la bâche 210 moins une largeur prédéterminée. Pour une largeur prédéterminée, par exemple de 30 cm, cela permet ainsi de laisser 15 cm de chaque côté pour que la bâche 210 recouvre chaque extrémité du jonc 240.Preferably, a pair of rods 240 is provided by bars 230. The width of each rod 240 is less than or equal to the width of the tarpaulin 210, and preferably strictly less than the width of the tarpaulin 210, which improves sealing. the cover 210 on the margins of the swimming pool. In this case, provision is made for the width of each ring 240 to be equal to the width of the tarpaulin 210 minus a predetermined width. For a predetermined width, for example 30 cm, this thus makes it possible to leave 15 cm on each side so that the tarpaulin 210 covers each end of the ring 240.

De préférence, on prévoit que chaque barre 230 comprend un bouchon (non illustré) en forme arrondie à chacune de ses extrémités, afin d'éviter que celle-ci présente une arête qui risquerait d'abraser la bâche 210.Preferably, provision is made for each bar 230 to include a plug (not shown) in rounded shape at each of its ends, in order to prevent the latter from presenting an edge which would risk abrading the cover 210.

Par exemple, chaque barre 230 présente en coupe transversale une section rectiligne 250 parallèle à la bâche 210, et une section arrondie, opposée à la section rectiligne.For example, each bar 230 has in cross section a rectilinear section 250 parallel to the tarpaulin 210, and a rounded section, opposite the rectilinear section.

Pour permettre le passage des joncs 240, une barre 230 comprend une gorge respective par jonc 240, dont le diamètre est supérieur ou égal au diamètre du jonc 240 et dont l'ouverture est inférieure audit diamètre.To allow the passage of the rods 240, a bar 230 comprises a respective groove by rod 240, the diameter of which is greater than or equal to the diameter of the rod 240 and the opening of which is smaller than said diameter.

Avantageusement, le profil d'une barre 230 est dissymétrique par rapport au plan de la bâche 210 et symétrique par rapport à un plan perpendiculaire au plan de la bâche 210, ce qui permet non seulement de pouvoir faciliter l'enroulement de la bâche 210 à barres 230 mais aussi de pouvoir monter une barre 230 dans la bâche 210 indistinctement dans un sens ou dans l'autre.Advantageously, the profile of a bar 230 is asymmetrical with respect to the plane of the tarpaulin 210 and symmetrical with respect to a plane perpendicular to the plane of the tarpaulin 210, which not only makes it possible to facilitate the winding of the tarpaulin 210 to bars 230 but also to be able to mount a bar 230 in the tarpaulin 210 indiscriminately in one direction or the other.

De préférence, la dernière barre 230 de la bâche 210, c'est à dire la barre la plus proche du tube d'enroulement 20, comprend deux galets de guidage (non illustrés) qui viennent agripper la rampe de guidage 90 des deux blocs, ce qui permet de venir plaquer la bâche 210 au sol 200.Preferably, the last bar 230 of the tarpaulin 210, that is to say the bar closest to the winding tube 20, comprises two guide rollers (not shown) which grip the guide ramp 90 of the two blocks, which allows the tarpaulin 210 to be placed on the ground 200.

La bâche 210 est reliée au tube d'enroulement 20 par un ensemble d'au moins une sangle de liaison 260, de préférence non élastique ou très peu élastique.The tarpaulin 210 is connected to the winding tube 20 by a set of at least one connecting strap 260, preferably inelastic or very inelastic.

De même, à l'autre extrémité de la bâche 210, ladite bâche 210 est de préférence reliée à un ensemble d'au moins point fixe par un ensemble d'au moins deux sangles de préférence non élastiques ou très peu élastiques.Likewise, at the other end of the tarpaulin 210, said tarpaulin 210 is preferably connected to a set of at least fixed point by a set of at least two straps which are preferably non-elastic or very poorly elastic.

Barres d'extrémitéEnd bars

La bâche 210 à barres 230 comprend deux barres 230 d'extrémité, positionnées aux deux extrémités de la bâche 210 dans le sens de sa longueur, c'est à dire dans le sens d'enroulement, et un ensemble de barres 230 intermédiaires. Avantageusement, toutes les barres 230 intermédiaires sont positionnées sur la face inférieure de la bâche 210, et les 2 barres 230 d'extrémité sont positionnées sur la face supérieure de la bâche 210.The tarpaulin 210 with bars 230 comprises two end bars 230, positioned at the two ends of the tarpaulin 210 in the direction of its length, that is to say in the winding direction, and a set of intermediate bars 230. Advantageously, all the intermediate bars 230 are positioned on the lower face of the tarpaulin 210, and the two end bars 230 are positioned on the upper face of the tarpaulin 210.

On peut prévoir que la bâche 210 comprend un ensemble de trous traversants permettant d'évacuer l'eau de pluie ou de fonte de neige, disposés entre au moins deux barres 230 adjacentesProvision can be made for the tarpaulin 210 to include a set of through holes allowing rainwater or snowmelt water to be evacuated, arranged between at least two adjacent bars 230.

On peut prévoir d'équiper la bâche 210 de moyens d'accrochage rapide à l'ensemble d'au moins un point fixe, par exemple un tendeur excentrique.Provision can be made to equip the tarpaulin 210 with rapid attachment means to the assembly with at least one fixed point, for example an eccentric tensioner.

En fonctionnement, l'une des extrémités de la bâche 210 est accrochée à l'ensemble d'au moins un point fixe et l'autre extrémité de la bâche 210 est accrochée au tube d'enroulement 20.In operation, one end of the tarpaulin 210 is hooked to the assembly of at least one fixed point and the other end of the tarpaulin 210 is hooked to the winding tube 20.

DéroulementProcess

Lors du déroulement de la bâche 210, l'enrouleur 10 est positionné à une extrémité de la piscine.During the unwinding of the cover 210, the reel 10 is positioned at one end of the pool.

La mise en route du moteur 80 entraîne les roues motrices et l'arbre de transmission 30. La roue libre 72 montée sur le tube d'enroulement 20 débraye. Ce sont alors les roues motrices qui font déplacer l'enrouleur 10 selon une trajectoire rectiligne.The starting of the motor 80 drives the driving wheels and the transmission shaft 30. The freewheel 72 mounted on the winding tube 20 disengages. It is then the driving wheels which cause the reel 10 to move along a rectilinear path.

Dans un mode de réalisation, la carte électronique 220 est reliée à un capteur de détection de couple 120, en l'espèce le capteur est intégré à la carte électronique sous forme de seuil de courant dont la valeur est prédéterminée, et comprend un programme d'ordinateur configuré pour stopper le moteur 80, donc l'avancée de l'enrouleur 10, lorsque le couple détecté est supérieur à une valeur seuil prédéterminée.In one embodiment, the electronic card 220 is connected to a torque detection sensor 120, in this case the sensor is integrated into the electronic card in the form of a current threshold whose value is predetermined, and comprises a program d computer configured to stop the motor 80, therefore the advance of the reel 10, when the detected torque is greater than a predetermined threshold value.

Une fois déroulée, lorsque le moteur 80 est stoppé, la bâche 210 reste en tension et un utilisateur peut alors attacher l'extrémité de la bâche 210 à un autre ensemble d'au moins un point fixe, de préférence par des moyens d'accrochage rapide, ladite extrémité de la bâche 210 étant également toujours reliée au tube d'enroulement 20 par un ensemble d'au moins deux sangles.Once unrolled, when the motor 80 is stopped, the tarpaulin 210 remains under tension and a user can then attach the end of the tarpaulin 210 to another set of at least one fixed point, preferably by hooking means rapid, said end of the cover 210 also always being connected to the winding tube 20 by a set of at least two straps.

La vitesse de rotation de l'arbre de transmission 30 est supérieure à celle du tube d'enroulement 20, ce qui permet de conserver la bâche 210 en tension.The speed of rotation of the transmission shaft 30 is greater than that of the winding tube 20, which makes it possible to keep the tarpaulin 210 in tension.

EnroulementWinding

Pour l'enroulement de la bâche 210, l'actionnement du moteur 80 entraîne en rotation le tube d'enroulement 20.For the winding of the tarpaulin 210, the actuation of the motor 80 drives the winding tube 20 in rotation.

La roue libre des roues motrices débraye celles-ci, c'est donc l'enroulement de la bâche 210 qui entraîne la translation de l'enrouleur 10. Le moteur 80 entraîne la rotation du tube d'enroulement 20 mais la rotation de l'arbre de transmission 30 n'est entraînée que par sa roue libre.The freewheel of the drive wheels disengages the latter, so it is the winding of the cover 210 which drives the translation of the reel 10. The motor 80 drives the rotation of the winding tube 20 but the rotation of the transmission shaft 30 is only driven by its freewheel.

La vitesse de rotation du tube d'enroulement est de préférence constante. Au cours de l'enroulement, la vitesse linéaire de déplacement augmente donc avec l'enroulement. La roue motrice étant débrayée, la vitesse de rotation de l'arbre de transmission 30 reste inférieure ou égale à la vitesse de rotation du tube d'enroulement, par conséquent la bâche 210 reste tendue lors de l'enroulement.The speed of rotation of the winding tube is preferably constant. During the winding, the linear displacement speed therefore increases with the winding. The drive wheel being disengaged, the speed of rotation of the transmission shaft 30 remains lower or equal to the speed of rotation of the winding tube, consequently the tarpaulin 210 remains stretched during winding.
