Definitions

  • the present invention relates to the technical field of cord winders associated with electrical devices provided with a cord, and used at variable distances from the electrical power source.
  • the present invention also relates to the field of canister vacuums, and more particularly to the field of portable compact canister vacuums whose size and / or weight are reduced.
  • Document FR 2 642 638 discloses an electric cord reel, the body of the drum of which is partially hollowed out around its hub. This recess is used to allow circulation of cooling air in the cord reel, preventing heat build-up in the coiled cord mass.
  • the winding of the cord is carried out on a rim having a relatively large diameter, generally greater than the height of the reel, so that the reel appears rather flat than high.
  • This space is all the more significant as a reel generally has a brake allowing the drum to be blocked when a certain length of cord has been unwound.
  • This brake is essentially arranged on the periphery of the reel or on the cheek of the drum.

  • the base also includes a disconnection pedal provided to allow the body of the device to be removed from said base.
  • This solution has the advantage of limiting the weight and size of the movable part of the device since the reel constitutes a base separate from the body of the device. The user only needs to move the mobile part while the base remains fixed. When the body of the device is detached from the base, the user can freely unwind the cord connecting the body of the device to the base.
  • This solution however has the drawback of authorizing the rewinding of the cord only on intervention of the user. The unrolled cord remains blocked until the user places the body of the device on the base, or presses himself, for example with the foot, on

Description

ENROULEUR POUR ASPIRATEUR HOSE REEL FOR VACUUM CLEANER
DOMAINE TECHNIQUETECHNICAL AREA
La présente invention se rapporte au domaine technique des enrouleurs de cordons associés à des appareils électriques munis d'un cordon, et utilisés à des distances variables de la source d'alimentation électrique. La présente invention se rapporte également au domaine des aspirateurs traîneaux, et plus particulièrement au domaine des aspirateurs traîneaux compacts portables dont l'encombrement et/ou le poids sont réduits.The present invention relates to the technical field of cord winders associated with electrical devices provided with a cord, and used at variable distances from the electrical power source. The present invention also relates to the field of canister vacuums, and more particularly to the field of portable compact canister vacuums whose size and / or weight are reduced.
TECHNIQUE ANTERIEUREPRIOR ART
Il est connu, par le document FR 2 642 638, un enrouleur de cordon électrique dont le corps du tambour est partiellement évidé autour de son moyeu. Cet évidement est utilisé afin de permettre une circulation d'air de refroidissement dans l'enrouleur du cordon, évitant une accumulation de chaleur dans la masse enroulée de cordon. Ainsi, l'enroulement du cordon est réalisé sur une jante présentant un diamètre relativement important, généralement supérieur à la hauteur de l'enrouleur, de sorte que l'enrouleur apparaît plutôt plat que haut.Document FR 2 642 638 discloses an electric cord reel, the body of the drum of which is partially hollowed out around its hub. This recess is used to allow circulation of cooling air in the cord reel, preventing heat build-up in the coiled cord mass. Thus, the winding of the cord is carried out on a rim having a relatively large diameter, generally greater than the height of the reel, so that the reel appears rather flat than high.
Par ailleurs, il est connu et classique d'utiliser un ressort d'enroulement de type ruban dont une extrémité est solidaire du bâti de l'aspirateur et l'autre extrémité solidaire du tambour de l'enrouleur, de telle sorte que la rotation du tambour, par le déroulement du cordon, tende le ressort qui exerce alors une action de rappel vers sa position initiale. De tels ressorts présentent un coefficient de torsion suffisant pour permettre un réenroulement du cordon dès qu'une faible longueur de cordon est déroulée. Dès lors, lorsque le cordon est totalement déroulé, le couple de torsion du ressort de rappel devient très élevé, de sorte que le cordon est réenroulé de façon brusque et rapide, pouvant occasionner des dommages aux objets environnants, voire aux personnes présentes. Il pourrait être envisagé de diminuer la raideur du ressort afin de ne pas présenter cet inconvénient. Cependant, un tel ressort ne pourrait enrouler totalement le cordon, et une portion du cordon devrait être enroulée manuellement, présentant un inconvénient d'utilisation certain.Furthermore, it is known and conventional to use a ribbon-type winding spring, one end of which is secured to the frame of the vacuum cleaner and the other end of which is secured to the drum of the reel, so that the rotation of the drum, by the unwinding of the cord, tightens the spring which then exerts a return action towards its initial position. Such springs have a sufficient twist coefficient to allow the cord to be rewound as soon as a short length of cord is unwound. Therefore, when the cord is fully unwound, the torsion torque of the return spring becomes very high, so that the cord is rewound suddenly and quickly, which can cause damage to surrounding objects, or even to people present. It could be envisaged to reduce the stiffness of the spring so as not to have this drawback. However, such a spring could not completely wind the cord, and a portion of the cord should be wound manually, having a certain drawback of use.
II est surprenant de constater, que les configurations comportant un tambour tel que précédemment décrit, où l'enroulement du cordon a lieu sur une jante au diamètre conséquent, permettent de résoudre le problème précédemment cité. En effet ces configurations permettent de réduire le nombre de tours nécessaires à l'enroulement total du cordon. De ce fait, en utilisant un ressort dont la raideur permet de réenrouler toute portion du cordon déroulée, le couple maximal, correspondant au déroulement total du cordon, est diminué, évitant ainsi tout désagrément lors du rembobinage du cordon. De tels enrouleurs présentent donc un intérêt tout particulier.It is surprising to note that the configurations comprising a drum as described above, where the winding of the cord takes place on a rim with a consequent diameter, make it possible to solve the problem mentioned above. Indeed, these configurations make it possible to reduce the number of turns necessary for the total winding of the cord. Therefore, by using a spring whose stiffness makes it possible to rewind any portion of the unwound cord, the maximum torque, corresponding to the total unwinding of the cord, is reduced, thus avoiding any inconvenience during rewinding of the cord. Such reels are therefore of particular interest.
Cependant, de tels enrouleurs sont encombrants car présentant un diamètre important.However, such reels are bulky because they have a large diameter.
Cet encombrement est d'autant plus conséquent qu'un enrouleur dispose généralement d'un frein permettant de bloquer le tambour lorsqu'une certaine longueur de cordon a été déroulée. Ce frein est essentiellement disposé en périphérie de l'enrouleur ou sur la joue du tambour.This space is all the more significant as a reel generally has a brake allowing the drum to be blocked when a certain length of cord has been unwound. This brake is essentially arranged on the periphery of the reel or on the cheek of the drum.
Un des buts de la présente invention est de réduire l'encombrement de tels dispositifs, pour un appareil électroménager, de type aspirateur.One of the aims of the present invention is to reduce the size of such devices, for a household appliance, of the vacuum cleaner type.
Par ailleurs, le document JP 05 309 509 décrit un aspirateur comportant un corps principal d'aspirateur connectable mécaniquement sur un socle dans lequel est disposé un enrouleur de cordon électrique, ledit cordon reliant le socle au corps de l'appareil. Le socle comporte un bouton de réenroulement prévu pour être actionné par le corps de l'appareil lors de sa mise en place sur le socle. Le socle comporte également une pédale de déconnexion prévue pour permettre le retrait du corps de l'appareil dudit socle. Cette solution présente l'avantage de limiter le poids et l'encombrement de la partie mobile de l'appareil puisque l'enrouleur constitue un socle distinct du corps de l'appareil. L'utilisateur n'a besoin de déplacer que la partie mobile alors que le socle reste fixe. Lorsque le corps de l'appareil est désolidarisé du socle, l'utilisateur peut dérouler librement le cordon reliant le corps de l'appareil au socle. Cette solution présente toutefois l'inconvénient d'autoriser le réenroulement du cordon uniquement sur intervention de l'utilisateur. Le cordon déroulé reste bloqué jusqu'à ce que l'utilisateur replace le corps de l'appareil sur le socle, ou appuie lui-même, par exemple avec le pied, sur le bouton de réenroulement.Furthermore, document JP 05 309 509 describes a vacuum cleaner comprising a main vacuum cleaner body that can be mechanically connected to a base in which an electric cord winder is arranged, said cord connecting the base to the body of the appliance. The base has a rewind button designed to be actuated by the body of the device when it is placed on the base. The base also includes a disconnection pedal provided to allow the body of the device to be removed from said base. This solution has the advantage of limiting the weight and size of the movable part of the device since the reel constitutes a base separate from the body of the device. The user only needs to move the mobile part while the base remains fixed. When the body of the device is detached from the base, the user can freely unwind the cord connecting the body of the device to the base. This solution however has the drawback of authorizing the rewinding of the cord only on intervention of the user. The unrolled cord remains blocked until the user places the body of the device on the base, or presses himself, for example with the foot, on the rewind button.
Un autre objet de l'invention vise à remédier à l'inconvénient précité, et à fournir à l'utilisateur le choix du mode de réenroulement du cordon : différé sur commande de l'utilisateur, immédiat, ou permanent en sélectionnant le mode de réenroulement choisi.Another object of the invention is to remedy the aforementioned drawback, and to provide the user with the choice of the cord rewinding mode: deferred at the user's command, immediate, or permanent by selecting the rewinding mode. selected.
Un autre objet de l'invention vise à fournir un ensemble électroménager comportant un appareil électrique, notamment un aspirateur, dont le poids et l'encombrement sont réduits, et qui offre une grande facilité d'utilisation.Another object of the invention is to provide a household appliance comprising an electrical appliance, in particular a vacuum cleaner, whose weight and size are reduced, and which offers great ease of use.
EXPOSE DE L'INVENTIONSTATEMENT OF THE INVENTION
L'un des buts assigné à l'invention est atteint avec un enrouleur de cordon électrique pour appareil électroménager, notamment un aspirateur, comprenant un tambour comportant un moyeu prolongé radialement par un disque, en périphérie duquel se trouve une jante dont les bords supportent chacun un flasque constituant, avec la jante, une zone annulaire d'enroulement et de retenue du cordon électrique, un ressort disposé autour du moyeu, susceptible d'être tendu par la rotation du tambour lors du déroulement du cordon, ainsi qu'un assemblage de blocage du tambour comportant un frein prévu pour empêcher le tambour de l'enrouleur de tourner dans le sens de l'enroulement du cordon électrique, et un bouton de commande prévu pour coopérer avec l'assemblage de blocage, caractérisé en ce que ledit frein est agencé dans l'espace intérieur défini par la jante de telle sorte à venir en appui contre la face interne de ladite jante.One of the objects assigned to the invention is achieved with an electric cord winder for household appliances, in particular a vacuum cleaner, comprising a drum comprising a hub extended radially by a disc, at the periphery of which is a rim whose edges each support a flange constituting, with the rim, an annular zone for winding and retaining the electrical cord, a spring disposed around the hub, capable of being stretched by the rotation of the drum during the unwinding of the cord, as well as an assembly of blocking of the drum comprising a brake provided to prevent the drum of the reel from rotating in the direction of winding of the electric cord, and a control button provided to cooperate with the blocking assembly, characterized in that said brake is arranged in the interior space defined by the rim so as to come into abutment against the inner face of said rim.
En disposant ainsi le frein dans l'espace intérieur de la jante, le volume de l'enrouleur n'est pas augmenté par le système de freinage, et garde une allure générale compacte, permettant de pouvoir l'intégrer dans la majorité des appareils électroménagers sans modification générale de l'esthétisme de ces appareils, tout en offrant une sécurité accrue lors du rembobinage du cordon, par diminution du couple de rappel maximal du ressort de moyeu.By thus placing the brake in the interior space of the rim, the volume of the retractor is not increased by the braking system, and keeps a general compact appearance, making it possible to be able to integrate it in the majority of household appliances. without general modification of the aesthetics of these devices, while offering increased security when rewinding the cord, by reducing the maximum return torque of the hub spring.
Selon un premier mode de réalisation de l'invention, le frein de l'enrouleur est situé à une extrémité d'une tige mobile en rotation ou en translation contre un moyen élastique, le bouton de commande étant situé en l'autre extrémité de la tige ou d'un prolongement et émergeant hors de l'enrouleur, ledit bouton étant susceptible de prendre une première position de réenroulement différé lorsque le moyen élastique est au repos, et une deuxième position d'enroulement immédiat en agissant sur le moyen élastique et en retirant le frein hors la face interne de la jante.According to a first embodiment of the invention, the brake of the reel is located at one end of a rod movable in rotation or in translation against an elastic means, the control button being located at the other end of the rod or an extension and emerging from the reel, said button being capable of assuming a first deferred rewinding position when the elastic means is at rest, and a second immediate winding position by acting on the elastic means and removing the brake from the inside of the rim.
Cette configuration permet de contrôler le déroulement et l'enroulement du cordon à l'aide d'un bouton de commande, facilitant l'utilisation de l'appareil équipé d'un tel enrouleur.This configuration makes it possible to control the unwinding and winding of the cord using a control button, facilitating the use of the device equipped with such a reel.
Avantageusement, selon ce dernier mode de réalisation, l'enrouleur et/ou la tige et/ou le bouton de commande comprennent des moyens de blocage du bouton de commande dans la deuxième position d'enroulement immédiat, permettant un déroulement et enroulement sous tension du ressort de moyeu, sans intervention de l'utilisateur.Advantageously, according to this latter embodiment, the reel and / or the rod and / or the control button comprise means for blocking the control button in the second immediate winding position, allowing the tension to be unwound and wound under tension. hub spring, without user intervention.
Il est en effet intéressant, pour de nombreux appareils tels que ponceuses, scies, fers à repasser..., de posséder une stricte longueur de cordon, l'excès de cordon pouvant être endommagé par l'appareil. Par ailleurs, pour des appareils nécessitant de fréquents déplacements, tels les aspirateurs, il est toujours désagréable d'être gêné dans son déplacement ou dans l'opération d'aspiration, par un cordon trop long. Selon un deuxième mode de réalisation de l'invention, le bouton de commande est monté mobile axialement contre un moyen de rappel et se prolonge par une tige, à travers une lumière d'un support solidaire du bâti de l'appareil électroménager ou d'une partie de celui-ci, la tige étant prévue pour coopérer avec une surface de came disposée sur un bras de l'assemblage de blocage monté mobile en translation, à l'extrémité duquel est monté un galet formant le frein prévu pour bloquer le tambour lorsque le bouton de commande est dans la position de réenroulement différé, le galet étant appliqué sur la jante du tambour par la translation de l'assemblage de blocage provoquée par la poussée de l'extrémité de la tige sur la surface de came lorsque le bouton est déplacé contre le moyen de rappel pour occuper une position d'enroulement immédiat.It is indeed interesting, for many devices such as sanders, saws, irons ..., to have a strict length of cord, excess cord can be damaged by the device. Furthermore, for devices requiring frequent movements, such as vacuum cleaners, it is always unpleasant to be hindered in its movement or in the suction operation, by a too long cord. According to a second embodiment of the invention, the control button is mounted axially movable against a return means and is extended by a rod, through a lumen of a support integral with the frame of the household appliance or part of it, the rod being provided to cooperate with a cam surface disposed on an arm of the blocking assembly mounted movable in translation, at the end of which is mounted a roller forming the brake intended to block the drum when the control button is in the delayed rewinding position, the roller being applied to the rim of the drum by the translation of the locking assembly caused by the pushing of the end of the rod on the cam surface when the button is moved against the return means to occupy an immediate winding position.
Cette configuration permet de disposer d'un bouton de commande mobile selon l'axe de l'enrouleur, ce qui permet, lorsque l'axe du tambour est disposé perpendiculairement au sol, de pouvoir actionner facilement un tel bouton de commande, notamment avec le pied, évitant ainsi à l'utilisateur de se baisser.This configuration provides a movable control button along the axis of the reel, which allows, when the axis of the drum is arranged perpendicular to the ground, to be able to easily actuate such a control button, especially with the foot, thus preventing the user from stooping.
Selon une troisième variante de réalisation, le bouton de commande est monté mobile axialement contre un moyen de rappel et se prolonge par une tige, à travers une lumière d'un support solidaire du bâti de l'appareil électroménager ou d'une partie de celui-ci, ladite tige étant prévue pour coopérer avec une surface de came disposée sur un bras de l'assemblage de blocage monté mobile en rotation et comportant un autre bras à l'extrémité duquel est monté un galet formant le frein prévu pour bloquer le tambour lorsque le bouton de commande est dans la position de réenroulement différé, le galet étant dégagé du tambour par la rotation de l'assemblage de blocage provoquée par la poussée de l'extrémité de la tige sur la surface de came lorsque le bouton est déplacé contre le moyen de rappel pour occuper une position d'enroulement immédiat.According to a third alternative embodiment, the control button is mounted axially movable against a return means and is extended by a rod, through a lumen of a support integral with the frame of the household appliance or a part of it here, said rod being designed to cooperate with a cam surface disposed on an arm of the blocking assembly mounted movable in rotation and comprising another arm at the end of which is mounted a roller forming the brake provided for blocking the drum when the control button is in the delayed rewinding position, the roller being released from the drum by the rotation of the locking assembly caused by the pushing of the end of the rod on the cam surface when the button is moved against the return means for occupying an immediate winding position.
Cette troisième configuration permet d'obtenir un dispositif plus compact et comportant un bras de levier pouvant augmenter la force avec laquelle le frein entre en contact avec la jante afin d'immobiliser le tambour. Elle permet également d'inverser le mouvement au niveau du bouton de commande, de sorte que ce dernier doit être maintenu contre le moyen de rappel afin d'obtenir un réenroulement du cordon, ce qui peut sembler, pour certaines personnes, une action plus logique donc plus compréhensible pour l'utilisateur, facilitant l'utilisation d'un tel enrouleur.This third configuration makes it possible to obtain a more compact device comprising a lever arm which can increase the force with which the brake comes into contact with the rim to immobilize the drum. It also makes it possible to reverse the movement at the level of the control button, so that the latter must be held against the return means in order to obtain a rewinding of the cord, which may seem, for some people, a more logical action. therefore more understandable for the user, facilitating the use of such a reel.
Selon un quatrième mode de réalisation de l'invention, le bouton de commande est monté mobile axialement contre un moyen de rappel et se prolonge par un secteur à travers une lumière d'un support solidaire du bâti de l'appareil électroménager ou d'une partie de celui-ci, le secteur comportant une butée, prévue pour coulisser dans un décrochement de la lumière, et un chanfrein, prévu pour coopérer avec une surface de came disposée sur un bras de l'assemblage de blocage, le moyen de blocage étant formé par la paroi du support contiguë au décrochement, l'assemblage étant monté mobile en rotation et comportant un autre bras à l'extrémité duquel est monté un galet formant le frein prévu pour bloquer le tambour lorsque le bouton est dans la position de réenroulement différé, le galet étant dégagé du tambour par la rotation de l'assemblage de blocage provoquée par la poussée du chanfrein sur la surface de came lorsque le bouton est enfoncé pour occuper la position d'enroulement immédiat, la butée étant maintenue contre le moyen de blocage sous l'action du moyen de rappel lorsque le bouton est tourné depuis la position d'enroulement immédiat pour occuper une position de réenroulement permanent, empêchant l'échappement de la surface de came du secteur.According to a fourth embodiment of the invention, the control button is mounted axially movable against a return means and is extended by a sector through a lumen of a support integral with the frame of the household appliance or of a part of it, the sector comprising a stop, intended to slide in a recess of the light, and a chamfer, intended to cooperate with a cam surface disposed on an arm of the blocking assembly, the blocking means being formed by the wall of the support contiguous to the recess, the assembly being mounted movable in rotation and comprising another arm at the end of which is mounted a roller forming the brake provided for locking the drum when the button is in the deferred rewinding position , the roller being released from the drum by the rotation of the locking assembly caused by the thrust of the chamfer on the cam surface when the button is pressed to occupy the po immediate winding position, the stop being held against the locking means under the action of the return means when the button is turned from the immediate winding position to occupy a permanent rewinding position, preventing escape from the surface sector cam.
Cette configuration autorise une position où le frein est maintenu débrayé afin de ne dérouler que la stricte longueur nécessaire de cordon, avec les avantages tels que précédemment décrits.This configuration allows a position where the brake is kept disengaged in order to unroll only the strict necessary length of cord, with the advantages as previously described.
Un autre des buts de l'invention est atteint à l'aide d'un socle pour appareil électrique, notamment pour aspirateur, comprenant au moins un patin de positionnement au sol dudit socle, un premier cordon électrique destiné à être relié électriquement au corps de l'appareil, ainsi qu'un second cordon électrique relié électriquement au premier cordon et prévu pour un branchement amovible à une prise du secteur, le premier cordon est prévu pour être enroulé sur un tambour d'un enrouleur de cordon disposé dans le socle, l'enrouleur, selon une première configuration, étant conforme à la présente invention et tel que précédemment décrit.Another object of the invention is achieved using a base for an electrical appliance, in particular for a vacuum cleaner, comprising at least one pad for positioning on the ground of said base, a first electrical cord intended to be electrically connected to the body of the appliance, as well as a second electrical cord electrically connected to the first cord and provided for a removable connection to a mains outlet, the first cord is intended to be wound on a drum of a cord reel arranged in the base, the reel, according to a first configuration, being conform to the present invention and as previously described.
Cette configuration permet de combiner les avantages d'un appareil à socle, par la légèreté résultante de l'appareil correspondant, aux avantages précédemment décrits de l'enrouleur conforme à la présente invention. Un avantage supplémentaire d'un tel socle est sa stabilité, due notamment à la faible hauteur de l'enrouleur.This configuration makes it possible to combine the advantages of a base device, by the resulting lightness of the corresponding device, with the previously described advantages of the reel according to the present invention. An additional advantage of such a base is its stability, due in particular to the low height of the reel.
Selon une seconde configuration, l'enrouleur comprend un ressort susceptible d'être tendu par le déroulement du premier cordon, et un assemblage de blocage débrayable adapté pour empêcher le tambour de l'enrouleur de tourner dans le sens de l'enroulement, le socle comportant un bouton de réenroulement, associé à un moyen de rappel, et prévu pour coopérer avec l'assemblage de blocage, le bouton de réenroulement étant prévu pour occuper soit :According to a second configuration, the reel comprises a spring capable of being stretched by the unwinding of the first cord, and a disengageable blocking assembly adapted to prevent the drum of the reel from rotating in the direction of winding, the base comprising a rewinding button, associated with a return means, and designed to cooperate with the blocking assembly, the rewinding button being provided for occupying either:
- une position de réenroulement différé dans laquelle l'assemblage de blocage engage le tambour de l'enrouleur de manière à empêcher ledit tambour de tourner dans le sens de l'enroulement,a deferred rewinding position in which the blocking assembly engages the drum of the reel so as to prevent said drum from rotating in the direction of winding,
- une position de réenroulement assisté dans laquelle le bouton débraye l'assemblage de blocage du tambour de l'enrouleur de manière à obtenir l'enroulement du premier cordon, le bouton de réenroulement dans la position de réenroulement assisté étant prévu pour reprendre la position de réenroulement différé sous l'action du moyen de rappel, le socle étant caractérisé en ce que le bouton de réenroulement peut également occuper une position de réenroulement immédiat dans laquelle le bouton engage l'assemblage de blocage et le débraye du tambour de l'enrouleur, de manière à obtenir l'enroulement du premier cordon, le bouton engageant ou étant engagé par un moyen de blocage prévu pour empêcher le désengagement dudit bouton de l'assemblage de blocage sous l'action du moyen de rappel.- an assisted rewinding position in which the button disengages the blocking assembly of the reel drum so as to obtain the winding of the first cord, the rewinding button in the assisted rewinding position being provided to resume the position of deferred rewinding under the action of the return means, the base being characterized in that the rewinding button can also occupy an immediate rewinding position in which the button engages the locking assembly and disengages the reel drum, so as to obtain the winding of the first cord, the button engaging or being engaged by a locking means provided to prevent the disengagement of said button from the assembly blocking under the action of the return means.
Ainsi l'utilisateur a la possibilité de choisir entre un réenroulement différé, lorsque le bouton de réenroulement occupe la position de réenroulement différé, et un réenroulement immédiat, lorsque le bouton de réenroulement occupe la position de réenroulement immédiat. L'utilisateur sélectionne la position du bouton de réenroulement et n'a plus à intervenir.Thus the user has the possibility of choosing between a deferred rewinding, when the rewinding button occupies the deferred rewinding position, and an immediate rewinding, when the rewinding button occupies the immediate rewinding position. The user selects the position of the rewind button and no longer has to intervene.
Selon ces configurations, avantageusement, le coefficient de friction du ou des patin(s) du socle présente une valeur minimale assurant que la force nécessaire pour déplacer le socle par glissement est supérieure à la force de rappel maximale du ressort de moyeu, obtenue lors du déroulement complet du cordon. Ainsi, l'utilisateur est certain, notamment dans le mode de réenroulement permanent, de pouvoir constamment se déplacer en enroulant ou déroulant le cordon sans entraîner le socle avec lui.According to these configurations, advantageously, the coefficient of friction of the pad (s) of the base has a minimum value ensuring that the force necessary to move the base by sliding is greater than the maximum return force of the hub spring, obtained during the complete unwinding of the cord. Thus, the user is certain, especially in the permanent rewinding mode, to be able to constantly move by winding or unwinding the cord without carrying the base with it.
De manière avantageuse le socle comporte un second enrouleur sur le tambour duquel est enroulé le second cordon.Advantageously, the base includes a second reel on the drum from which the second cord is wound.
Les buts assignés à l'invention sont également atteints avec un ensemble électroménager, caractérisé en ce qu'il comprend un socle selon l'invention et un appareil électrique, notamment aspirateur, dont le corps comporte une base prévue pour reposer sur le socle.The objects assigned to the invention are also achieved with a household appliance, characterized in that it comprises a base according to the invention and an electrical appliance, in particular a vacuum cleaner, the body of which comprises a base intended to rest on the base.
L'utilisateur bénéficie d'un ensemble électroménager pratique et maniable. Le socle selon l'invention offre un enrouleur de cordon perfectionné et le corps de l'appareil est compact et allégé, l'enrouleur de cordon étant séparé.The user benefits from a practical and handy household appliance. The base according to the invention offers an improved cord winder and the body of the device is compact and light, the cord winder being separate.
Avantageusement, le socle comporte des moyens d'accrochage et le corps comporte des moyens de verrouillage prévus pour coopérer avec les moyens d'accrochage.Advantageously, the base comprises attachment means and the body comprises locking means provided to cooperate with the attachment means.
Ainsi l'utilisateur peut assembler le corps et le socle, afin de maintenir en place le corps sur le socle. De manière avantageuse le corps comporte une poignée disposée sensiblement à l'opposé des moyens de verrouillage.Thus the user can assemble the body and the base, in order to hold the body in place on the base. Advantageously, the body comprises a handle disposed substantially opposite the locking means.
Ainsi l'utilisateur peut transporter aisément l'ensemble corps et socle.Thus the user can easily transport the body and base assembly.

L'enrouleur 37 est agencé dans un compartiment 25 d'un appareil électroménager ou d'une partie de celui-ci. Il comporte un tambour 7 constitué d'un moyeu 16, prolongé radialement par un disque 10. Une jante 9 est disposée à la périphérie de ce disque 10 et comporte deux flasques 8a et 8b orientés radialement et vers l'extérieur de la jante 9, de façon à ménager un espace annulaire d'enroulement d'un cordon électrique 20 prévu pour un branchement amovible à une prise secteur. L'enrouleur 37 comprend un ressort 14 susceptible d'être tendu par la rotation du tambour 7 suite au déroulement du cordon 20. L'enrouleur 37 comprend également un assemblage de blocage débrayable 27 adapté pour empêcher le tambour 7 de l'enrouleur 37 de tourner dans le sens de l'enroulement du cordon 20. Un bouton de réenroulement 4, associé à un moyen élastique 23, solidaire, par l'une de ses extrémités, du compartiment 25, est prévu pour coopérer avec l'assemblage de blocage 27, afin de débrayer ledit assemblage du tambour 7. Selon un premier mode de réalisation, l'assemblage de blocage 27 comporte une tige coudée 21 reliée au bouton de commande 4 et terminée par un frein 22 situé dans l'espace intérieur défini par la jante 9. Le ressort 23 est monté en compression de sorte qu'au repos, il maintienne la tige 21 et donc le frein 22 contre la face interne de la jante 9, immobilisant ainsi le tambour 7.The reel 37 is arranged in a compartment 25 of an appliance or a part thereof. It comprises a drum 7 consisting of a hub 16, extended radially by a disc 10. A rim 9 is disposed at the periphery of this disc 10 and comprises two flanges 8a and 8b oriented radially and towards the outside of the rim 9, so as to provide an annular space for winding an electric cord 20 provided for a removable connection to a power outlet. The reel 37 includes a spring 14 capable of being stretched by the rotation of the drum 7 following the unwinding of the cord 20. The reel 37 also includes a disengageable blocking assembly 27 adapted to prevent the drum 7 of the reel 37 from turning in the direction of the winding of the cord 20. A rewinding button 4, associated with an elastic means 23, secured, by one of its ends, to the compartment 25, is provided to cooperate with the locking assembly 27, in order to disengage said assembly from the drum 7. According to a first embodiment, the locking assembly 27 comprises a bent rod 21 connected to the control button 4 and terminated by a brake 22 located in the interior space defined by the rim 9. The spring 23 is mounted in compression so that at rest, it maintains the rod 21 and therefore the brake 22 against the internal face of the rim 9, thus immobilizing the drum 7.
Selon un deuxième mode de réalisation de l'enrouleur et présenté figure 2, la tige 21 est montée en rotation autour d'un axe 24 solidaire du compartiment 25.According to a second embodiment of the reel and shown in FIG. 2, the rod 21 is mounted in rotation about an axis 24 integral with the compartment 25.
Selon un troisième mode de réalisation présenté figure 3, le bouton 4 est monté mobile axialement et est prolongé par une tige 25, débouchant à travers une ouverture 29 d'un support 52. L'assemblage de blocage 27 comporte un bras 34, monté sur le support 52 par un pion 30 et mobile en translation sensiblement radiale dans une fenêtre 33 ménagée dans le bras 34. A l'une des extrémités de ce bras est monté un galet 57 réalisé avantageusement en un matériau de type caoutchouc. Avantageusement, le support 67 du galet permet à ce dernier, lorsque celui-ci est appliqué contre la jante du tambour par le moyen de blocage 27, de tourner librement autour de son axe lors de la rotation du tambour dans le sens du déroulement du cordon et d'être bloqué lors de la rotation du tambour dans le sens de l'enroulement du cordon. De tels galets sont connus et ne seront pas davantage détaillés dans la présente demande.According to a third embodiment shown in Figure 3, the button 4 is mounted axially movable and is extended by a rod 25, opening through an opening 29 of a support 52. The locking assembly 27 comprises an arm 34, mounted on the support 52 by a pin 30 and movable in substantially radial translation in a window 33 formed in the arm 34. At one end of this arm is mounted a roller 57 advantageously made of a rubber type material. Advantageously, the support 67 of the roller allows the latter, when the latter is applied against the rim of the drum by the locking means 27, to rotate freely around its axis during the rotation of the drum in the direction of unwinding of the cord and to be blocked when the drum is rotated in the direction of winding the cord. Such rollers are known and will not be further detailed in the present application.
L'autre extrémité du bras 34 est terminée par une surface de came 61. La tige 25 est positionnée de telle sorte à pouvoir coopérer avec la surface de came 61 par l'intermédiaire du bouton 4 afin de déplacer l'assemblage de blocage 27 pour appliquer le galet 57 contre la jante 9. La tige 25 peut être terminée par un chanfrein afin de coopérer plus facilement avec la surface de came 61. La figure 3 présente le cas où le frein n'est pas appliqué.The other end of the arm 34 is terminated by a cam surface 61. The rod 25 is positioned so as to be able to cooperate with the surface of cam 61 by means of the button 4 in order to move the locking assembly 27 to apply the roller 57 against the rim 9. The rod 25 can be terminated by a chamfer in order to cooperate more easily with the cam surface 61. The Figure 3 shows the case where the brake is not applied.
Selon un quatrième mode de réalisation de l'invention présenté figure 4, l'assemblage de blocage 27 est monté mobile en rotation autour d'un axe 55 et comporte un premier bras 56 à l'extrémité duquel est monté un galet 57 réalisé avantageusement en un matériau de type caoutchouc. Un moyen élastique 58 disposé entre le premier bras 56 et un appui 59 tend à amener le galet 57 contre le tambour 7, afin de bloquer celui-ci. L'assemblage 27 comporte un second bras 60 terminé par une surface de came 61. La tige 25 est positionnée afin de pouvoir coopérer avec la surface de came 61 et peut être, à ce titre, terminée par un chanfrein.According to a fourth embodiment of the invention presented in FIG. 4, the blocking assembly 27 is mounted movable in rotation about an axis 55 and comprises a first arm 56 at the end of which is mounted a roller 57 advantageously made of a rubber-like material. An elastic means 58 disposed between the first arm 56 and a support 59 tends to bring the roller 57 against the drum 7, in order to block the latter. The assembly 27 comprises a second arm 60 terminated by a cam surface 61. The rod 25 is positioned so as to be able to cooperate with the cam surface 61 and can be, as such, terminated by a chamfer.
Avantageusement, selon l'un des modes de réalisation précédemment décrits, l'assemblage de blocage 27 peut être maintenu en permanence dans l'état correspondant au débrayage du frein, par tout moyen mécanique par ailleurs connu. Ces moyens peuvent être composés de crochets solidaires du compartiment de l'enrouleur ou d'une pièce d'écartement permettant de maintenir comprimé le ressort pour les premiers et deuxième mode de réalisation, d'un ressort de rappel lié au bras 34 pour le troisième mode de réalisation, le quatrième mode de réalisation pouvant être modifié selon la figure 13 afin d'obtenir un tel effet. Ces moyens de blocage ne sont pas limités aux simples exemples cités, et toute autre configuration peut être utilisée sans sortir du cadre de la présente invention. Dans cette configuration, l'enrouleur présente un mode fonctionnement «autoreverse» ou immédiat, où le cordon est enroulé ou déroulé selon les sollicitations de l'utilisateur.Advantageously, according to one of the previously described embodiments, the blocking assembly 27 can be permanently maintained in the state corresponding to the release of the brake, by any otherwise known mechanical means. These means may be composed of hooks integral with the reel compartment or of a spacer allowing the spring to be compressed for the first and second embodiment, a return spring linked to the arm 34 for the third. embodiment, the fourth embodiment can be modified according to FIG. 13 in order to obtain such an effect. These blocking means are not limited to the simple examples cited, and any other configuration can be used without departing from the scope of the present invention. In this configuration, the reel has an “autoreverse” or immediate operating mode, where the cord is wound or unwound according to the user's demands.
Un tel enrouleur présente donc l'avantage d'un stockage optimisé du cordon en vue de son enroulement sous l'effet d'un ressort de rappel, tout en gardant une forme compacte, obtenue notamment par la disposition du frein, dans l'espace interne de la jante du tambour de l'enrouleur. Un autre but de l'invention concerne un appareil électrique muni d'un socle enrouleur. Le socle 1 selon l'invention comporte un boîtier 3 dans lequel est disposé un enrouleur 12 de cordon comprenant un tambour 7 sur lequel est enroulé un premier cordon électrique 20, ainsi qu'un second cordon électrique 19 relié électriquement au premier cordon 20 et prévu pour un branchement amovible à une prise secteur. L'enrouleur 12 comprend un ressort 14 susceptible d'être tendu par le déroulement du premier cordon 20. L'enrouleur 12 comprend également un assemblage de blocage débrayable 27 adapté pour empêcher le tambour 7 de l'enrouleur 12 de tourner dans le sens de l'enroulement. Un bouton de réenroulement 4, associé à un moyen de rappel 28, est disposé sur le boîtier 3. Le bouton 4 est prévu pour coopérer avec l'assemblage de blocage 27, afin de débrayer ledit assemblage du tambour 7. Le boîtier 3 comporte une face inférieure 5, prévue pour être posée sur le sol ou sur tout support adéquat, et avantageusement munie de patins 40 en matériau antidérapant. Le boîtier 3 comporte également une face supérieure 6, avantageusement sensiblement parallèle à la face inférieure 5, et prévue pour recevoir un corps 2 d'un appareil électrique, par exemple un aspirateur, tel que représenté à la figure 5.Such a reel therefore has the advantage of optimized storage of the cord for winding under the effect of a return spring, while keeping a compact shape, obtained in particular by the arrangement of the brake, in space internal of the reel drum rim. Another object of the invention relates to an electrical device provided with a winding base. The base 1 according to the invention comprises a housing 3 in which is disposed a cord winder 12 comprising a drum 7 on which is wound a first electrical cord 20, as well as a second electrical cord 19 electrically connected to the first cord 20 and provided for removable connection to a power outlet. The reel 12 comprises a spring 14 capable of being tensioned by the unwinding of the first cord 20. The reel 12 also includes a disengageable blocking assembly 27 adapted to prevent the drum 7 of the reel 12 from turning in the direction of the winding. A rewinding button 4, associated with a return means 28, is disposed on the housing 3. The button 4 is provided to cooperate with the locking assembly 27, in order to disengage said assembly from the drum 7. The housing 3 comprises a lower face 5, intended to be placed on the ground or on any suitable support, and advantageously provided with pads 40 of non-slip material. The housing 3 also includes an upper face 6, advantageously substantially parallel to the lower face 5, and designed to receive a body 2 of an electrical appliance, for example a vacuum cleaner, as shown in FIG. 5.
Le corps 2 de l'appareil est relié électriquement au socle 1 par le premier cordon 20. Avantageusement le cordon 20 se termine par une prise électrique femelle prévue pour être branchée sur une prise mâle disposée sur le corps 2. Le corps 2 de l'appareil comporte une base 11 prévue pour reposer sur le socle 1 , avantageusement une poignée 35 ainsi qu'une sangle 36 de transport. Les patins 40 assurent au socle de ne pas glisser sur le sol lorsque le cordon 20 est déroulé, même lorsque le cordon est déroulé en totalité, induisant un couple de rappel important du ressort 14.The body 2 of the device is electrically connected to the base 1 by the first cord 20. Advantageously, the cord 20 ends in a female electrical outlet intended to be connected to a male outlet disposed on the body 2. The body 2 of the device comprises a base 11 intended to rest on the base 1, advantageously a handle 35 and a strap 36 for transport. The pads 40 ensure that the base does not slide on the ground when the cord 20 is unwound, even when the cord is fully unwound, inducing a significant return torque of the spring 14.
Selon une version préférée de l'invention, représentée aux figures 6 àAccording to a preferred version of the invention, shown in Figures 6 to
13, le socle 1 comporte des moyens d'accrochage 31 prévus pour coopérer avec des moyens de verrouillage 32 disposés sur le corps 2 de l'appareil. L'utilisateur peut ainsi solidariser le corps 2 au socle 1. Selon le mode de réalisation représenté aux figures 6 et 7, le socle 1 comporte sur la face supérieure 6 du boîtier 3 une gorge annulaire 41 prévue pour recevoir un anneau 42 avantageusement disposé sur la base 11 du corps 2. La gorge 41 comporte des ergots 43 disposés régulièrement sur la circonférence de ladite gorge, formant les moyens d'accrochage 31. L'anneau 42 comporte des oreilles 44 disposées régulièrement sur sa circonférence, formant les moyens de verrouillage 32. Les moyens d'accrochage 31 et les moyens de verrouillage 32 forment ainsi un système à baïonnette. D'autres modes de réalisation pour les moyens d'accrochage 31 et les moyens de verrouillage 32 sont envisageables. Les moyens d'accrochage 31 et les moyens de verrouillage 32 peuvent former par exemple un système à vis quart de tour (non représenté aux figures).13, the base 1 comprises hooking means 31 provided to cooperate with locking means 32 arranged on the body 2 of the device. The user can thus secure the body 2 to the base 1. According to the embodiment shown in Figures 6 and 7, the base 1 has on the face upper 6 of the housing 3 an annular groove 41 provided for receiving a ring 42 advantageously disposed on the base 11 of the body 2. The groove 41 comprises lugs 43 regularly arranged on the circumference of said groove, forming the attachment means 31. L 'ring 42 includes ears 44 regularly arranged on its circumference, forming the locking means 32. The hooking means 31 and the locking means 32 thus form a bayonet system. Other embodiments for the attachment means 31 and the locking means 32 can be envisaged. The hooking means 31 and the locking means 32 can for example form a quarter-turn screw system (not shown in the figures).
Avantageusement la poignée 35 est disposée sensiblement à l'opposé de la base 11 par rapport au centre de gravité du corps 2, tel que le montre par exemple la figure 5. L'utilisateur peut ainsi saisir aisément le corps 2 au moyen de la poignée 35 et verrouiller ou déverrouiller le corps 2 comportant les moyens de verrouillage 32 par rapport au socle 1 comportant les moyens d'accrochage 31 (non représentés à la figure 5).Advantageously, the handle 35 is disposed substantially opposite the base 11 relative to the center of gravity of the body 2, as shown for example in FIG. 5. The user can thus easily grasp the body 2 by means of the handle 35 and lock or unlock the body 2 comprising the locking means 32 relative to the base 1 comprising the hooking means 31 (not shown in FIG. 5).
Selon le mode de réalisation montré aux figures 8 à 13, le bouton 4 est monté mobile axialement contre le moyen de rappel 28 dans un logement cylindrique 50 formé par les parois 51 d'un support 52 solidaire du boîtier 3. Le support 52 comporte une ouverture 53 à travers laquelle le bouton 4 se prolonge par un secteur 54. L'assemblage de blocage 27 est monté mobile en rotation autour d'un axe 55 et comporte un premier bras 56 à l'extrémité duquel est monté un galet 57 réalisé avantageusement en un matériau de type caoutchouc. Un moyen élastique 58 disposé entre le premier bras 56 et un appui 59 tend à amener le galet 57 contre le tambour 7, tel que représenté à la figure 9. L'assemblage 27 comporte un second bras 60 terminé par une surface de came 61. Le secteur 54 comporte un chanfrein 62 prévu pour coopérer avec la surface de came 61. Le secteur 54 comporte une butée 64, prévue pour coulisser dans un décrochement 63 de l'ouverture 53.According to the embodiment shown in Figures 8 to 13, the button 4 is mounted axially movable against the return means 28 in a cylindrical housing 50 formed by the walls 51 of a support 52 secured to the housing 3. The support 52 has a opening 53 through which the button 4 is extended by a sector 54. The blocking assembly 27 is mounted movable in rotation about an axis 55 and comprises a first arm 56 at the end of which is mounted a roller 57 advantageously produced made of a rubber-like material. An elastic means 58 disposed between the first arm 56 and a support 59 tends to bring the roller 57 against the drum 7, as shown in FIG. 9. The assembly 27 comprises a second arm 60 terminated by a cam surface 61. The sector 54 comprises a chamfer 62 intended to cooperate with the cam surface 61. The sector 54 comprises a stop 64, intended to slide in a recess 63 of the opening 53.
Le fonctionnement du socle 1 selon l'invention, et de l'ensemble électroménager comprenant un socle 1 selon l'invention et un appareil électrique, notamment aspirateur, comportant un corps 2, est le suivant.The operation of the base 1 according to the invention, and of the assembly household appliances comprising a base 1 according to the invention and an electrical appliance, in particular a vacuum cleaner, comprising a body 2, is as follows.
Dans la configuration des figures 8 à 11, l'enrouleur 12 offre un réenroulement différé. Le réenroulement n'est obtenu que lorsque l'utilisateur agit sur le bouton 4, par exemple par l'intermédiaire du pied, ou lorsqu'il replace le corps 2 sur le socle 1. Le bouton de réenroulement 4 dans la position de réenroulement différé représentée à la figure 8 est susceptible d'être actionné par le corps 2 de l'appareil lorsque celui-ci est reposé sur le socle 1, de manière à atteindre la position de réenroulement assisté représentée à la figure 10. Le bouton de réenroulement 4 dans la position de réenroulement assisté est prévu pour reprendre la position de réenroulement différé sous l'action du moyen de rappel 28.In the configuration of FIGS. 8 to 11, the reel 12 offers deferred rewinding. The rewinding is only obtained when the user acts on the button 4, for example by means of the foot, or when he replaces the body 2 on the base 1. The rewinding button 4 in the deferred rewinding position shown in Figure 8 is capable of being actuated by the body 2 of the device when it is rested on the base 1, so as to reach the assisted rewinding position shown in Figure 10. The rewinding button 4 in the assisted rewinding position is provided to resume the deferred rewinding position under the action of the return means 28.
Dans les figures 8 et 9, le bouton de réenroulement 4 occupe une position de réenroulement différé dans laquelle l'assemblage de blocage 27 engage le tambour 7 de l'enrouleur 12 de manière à empêcher ledit tambour de tourner dans le sens de l'enroulement. Le galet 57 amené par le moyen élastique 58 contre le tambour 7 empêche le retour du ressort 14 vers sa position de repos. Dans cette position l'utilisateur peut dérouler le premier cordon 20 mais celui-ci reste déroulé lorsque l'utilisateur le relâche. Selon le mode de réalisation présenté aux figures, le bouton de réenroulement 4 en position de réenroulement différé est proéminent par rapport à la face supérieure 6 du socle 1.In FIGS. 8 and 9, the rewinding button 4 occupies a deferred rewinding position in which the locking assembly 27 engages the drum 7 of the reel 12 so as to prevent said drum from turning in the direction of winding. . The roller 57 brought by the elastic means 58 against the drum 7 prevents the return of the spring 14 to its rest position. In this position the user can unroll the first cord 20 but it remains unrolled when the user releases it. According to the embodiment presented in the figures, the rewinding button 4 in the deferred rewinding position is prominent relative to the upper face 6 of the base 1.
Dans les figures 10 et 11, le bouton de réenroulement 4 occupe une position de réenroulement assisté et débraye l'assemblage de blocage 27 du tambour 7 de l'enrouleur 12 de manière à obtenir l'enroulement du premier cordon 20. Lorsque le bouton 4 est enfoncé, sous l'action du corps 2 reposé ou verrouillé sur le socle 1, le secteur 54 monte à travers l'ouverture 53 et le chanfrein 62 repousse la surface de came 61, provoquant la rotation de l'assemblage de blocage 27, dégageant ainsi le galet 57 du tambour 7. L'assemblage de blocage est alors débrayé et le ressort 14 tend à entraîner le tambour 7 de l'enrouleur 12 dans le sens de l'enroulement. La figure 10 montre le corps 2 verrouillé sur le socle 1 par les moyens d'accrochage 31 coopérant avec les moyens de verrouillage 32. Lorsque le corps 2 est retiré du socle 1, le moyen de rappel 28 retourne vers sa position de repos et le bouton 4 reprend la position de réenroulement différé. Selon le mode de réalisation présenté aux figures, le bouton de réenroulement 4 en position de réenroulement assisté est enfoncé par rapport à la position de réenroulement différé.In FIGS. 10 and 11, the rewinding button 4 occupies an assisted rewinding position and disengages the locking assembly 27 of the drum 7 of the reel 12 so as to obtain the winding of the first cord 20. When the button 4 is pressed, under the action of the body 2 rested or locked on the base 1, the sector 54 rises through the opening 53 and the chamfer 62 pushes the cam surface 61, causing the rotation of the locking assembly 27, thus releasing the roller 57 from the drum 7. The locking assembly is then disengaged and the spring 14 tends to drive the drum 7 of the reel 12 in the winding direction. FIG. 10 shows the body 2 locked on the base 1 by the hooking means 31 cooperating with the locking means 32. When the body 2 is removed from the base 1, the return means 28 returns to its rest position and the button 4 returns to the delayed rewinding position. According to the embodiment shown in the figures, the rewinding button 4 in the assisted rewinding position is pressed relative to the deferred rewinding position.
Selon l'invention le bouton de réenroulement 4 peut également occuper une position de réenroulement immédiat dans laquelle le bouton 4 engage l'assemblage de blocage 27 et débraye l'assemblage de blocage 27 du tambour 7 de l'enrouleur 12, de manière à obtenir l'enroulement du premier cordon 20, le bouton 4 engageant un moyen de blocage 17 prévu pour empêcher le désengagement dudit bouton de l'assemblage de blocage 27 sous l'action du moyen de rappel 28. Tel que représenté à la figure 13, le moyen de blocage 17 est formé par la paroi du support 52 contiguë au décrochement 63.According to the invention, the rewinding button 4 can also occupy an immediate rewinding position in which the button 4 engages the locking assembly 27 and disengages the locking assembly 27 from the drum 7 of the reel 12, so as to obtain the winding of the first cord 20, the button 4 engaging a locking means 17 provided to prevent the disengagement of said button from the locking assembly 27 under the action of the return means 28. As shown in FIG. 13, the blocking means 17 is formed by the wall of the support 52 contiguous to the step 63.
Lors de la rotation du bouton 4 initialement en position de réenroulement assisté vers la position de réenroulement immédiat le secteur 54 tourne dans l'ouverture 53 et la butée 64 arrive en regard du moyen de blocage 17. Avantageusement le bord 66 du décrochement 63 forme une seconde surface de came facilitant le déplacement de la butée 64 vers le moyen de blocage 17. Lors du relâchement du bouton 4, le moyen de rappel 28 amène ou maintient la butée 64 au contact du moyen de blocage 17, empêchant l'échappement de la surface de came 61 du secteur 54. L'assemblage de blocage reste débrayé, le second bras 60 étant maintenu par le secteur 54, écartant ainsi le galet 57 du tambour 7. Selon le mode de réalisation présenté aux figures, le bouton de réenroulement 4 en position de réenroulement immédiat est tourné par rapport à la position de réenroulement assisté.During the rotation of the button 4 initially in the assisted rewinding position towards the immediate rewinding position, the sector 54 rotates in the opening 53 and the stop 64 comes opposite the locking means 17. Advantageously the edge 66 of the recess 63 forms a second cam surface facilitating the movement of the stop 64 towards the locking means 17. When the button 4 is released, the return means 28 brings or maintains the stop 64 in contact with the locking means 17, preventing the escape of the cam surface 61 of sector 54. The locking assembly remains disengaged, the second arm 60 being held by sector 54, thus moving the roller 57 away from the drum 7. According to the embodiment presented in the figures, the rewinding button 4 in the immediate rewinding position is rotated relative to the assisted rewinding position.
Lorsque le bouton de réenroulement est amené par l'utilisateur dans la position de réenroulement immédiat, l'assemblage de blocage reste constamment débrayé. Dans cette configuration l'enrouleur 12 offre un fonctionnement «autoreverse» ou immédiat. Le premier cordon 20 sort et rentre du socle 1 selon les sollicitations de l'utilisateur. Le bouton 4 conserve la position de réenroulement immédiat indépendamment de la présence ou non du corps 2 sur le socle 1 , tel que représenté à la figure 12.When the rewind button is brought by the user to the immediate rewind position, the locking assembly remains constantly disengaged. In this configuration the reel 12 offers a "autoreverse" or immediate operation. The first cord 20 leaves and returns from the base 1 according to the user's requests. The button 4 retains the immediate rewinding position regardless of the presence or not of the body 2 on the base 1, as shown in FIG. 12.
Selon une version avantageuse de l'invention représentée à la figure 14, le socle 1 comporte un second enrouleur 13 sur le tambour duquel est enroulé le second cordon 19. Le second enrouleur 13 comprend un ressort de rappel 15 susceptible d'être tendu par le déroulement du second cordon 19. L'utilisateur peut ainsi bénéficier de facilités de rangement pour le second cordon 19.According to an advantageous version of the invention shown in FIG. 14, the base 1 comprises a second winder 13 on the drum from which the second cord 19 is wound. The second winder 13 comprises a return spring 15 capable of being tensioned by the unwinding of the second cord 19. The user can thus benefit from storage facilities for the second cord 19.
Le second cordon 19 peut également bénéficier d'un moyen de blocage (non représenté aux figures), débrayable au moyen d'un second bouton de réenroulement, disposé par exemple sur un côté du socle 1 , le second bouton de réenroulement étant associé à un moyen de rappel et étant prévu pour débrayer le moyen de blocage, de manière à obtenir le réenroulement du second cordon 19, lorsque l'utilisateur actionne ledit second bouton contre le moyen de rappel. Selon une autre version de l'invention, également non représentée aux figures, le second bouton de réenroulement est disposé sur la face du socle prévue pour reposer sur le sol ou tout autre support adéquat, et est prévu pour débrayer le moyen de blocage, de manière à obtenir le réenroulement du second cordon 19, lorsque l'utilisateur soulève le corps 2, fixé au socle 1 par les moyens de verrouillage 32 coopérant avec les moyens d'accrochage 31, par exemple en saisissant la poignée 35 ou la sangle 36.The second cord 19 can also benefit from a locking means (not shown in the figures), disengageable by means of a second rewinding button, arranged for example on one side of the base 1, the second rewinding button being associated with a return means and being provided to disengage the blocking means, so as to obtain the rewinding of the second cord 19, when the user actuates said second button against the return means. According to another version of the invention, also not shown in the figures, the second rewinding button is arranged on the face of the base intended to rest on the ground or any other suitable support, and is provided to disengage the locking means, so as to obtain the rewinding of the second cord 19, when the user lifts the body 2, fixed to the base 1 by the locking means 32 cooperating with the hooking means 31, for example by grasping the handle 35 or the strap 36.
Selon le mode de réalisation représenté aux figures, le bouton 4 est disposé sur la face supérieure 6 du boîtier 3. A titre de variante le bouton 4 peut occuper d'autres emplacements, par exemple sur une face latérale du boîtier 3, le corps 2 de l'appareil étant prévu pour repousser le bouton 4 initialement en position de réenroulement différé vers la position de réenroulement assisté, lorsque ledit corps est posé ou verrouillé sur le socle 1.
