Description

La présente invention concerne généralement un dispositif d'aspiration utilisable sur au moins un niveau d'un bâtiment.The present invention generally relates to a suction device usable on at least one level of a building.

Elle a essentiellement pour objet un dispositif d'aspiration du type comportant une buse d'aspiration tenue à la main et reliée par un tuyau flexible à une conduite d'aspiration elle-même reliée à un collecteur d'aspiration centralisée.It essentially relates to a suction device of the type comprising a suction nozzle held in the hand and connected by a flexible hose to a suction pipe itself connected to a centralized suction manifold.

L'invention trouve notamment application dans le nettoyage industriel des bâtiments ou immeubles à plusieurs étages, comme par exemple le nettoyage interne des bureaux et des locaux.The invention finds particular application in the industrial cleaning of buildings or buildings with several floors, such as for example the internal cleaning of offices and premises.

On connaît un dispositif d'aspiration utilisable sur au moins un niveau d'un bâtiment. Ce dispositif consiste d'une part, à connecter sur un collecteur vertical d'aspiration centralisée, un ou plusieurs sous-collecteurs d'aspiration équipés de bouches d'aspiration qui sont installés en parallèle de manière fixe, à chaque niveau du bâtiment, et d'autre part, à brancher un tuyau flexible, successivement sur chacune des bouches d'aspiration d'un même sous-collecteur, afin d'assurer l'aspiration sur la totalité de la surface du niveau considéré. Chaque sous-collecteur comporte des bouches d'aspiration qui sont fixes. Ainsi, une buse d'aspiration et ses accessoires tels qu'un capteur de sol ou une brosse, peuvent être reliés à l'une de ces bouches d'aspiration par l'intermédiaire du tuyau flexible et enroulable, voir US-A 3 011 201.A suction device is known which can be used on at least one level of a building. This device consists on the one hand, in connecting to a vertical centralized suction manifold, one or more suction sub-collectors equipped with suction outlets which are installed in fixed parallel fashion, at each level of the building, and on the other hand, to connect a flexible pipe, successively to each of the suction outlets of the same sub-collector, in order to ensure the suction over the entire surface of the level considered. Each sub-collector has fixed suction outlets. Thus, a suction nozzle and its accessories such as a soil sensor or a brush, can be connected to one of these suction mouths by means of the flexible and rollable hose, see US-A 3,011 201.

Or, un tel dispositif d'aspiration, comportant des bouches d'aspiration à poste fixe sur un niveau donné du bâtiment, nécessite une installation de sous-collecteurs sur une grande longueur, sur le plan horizontal de chaque niveau du bâtiment. Cette installation s'effectue lors de la construction et de l'aménagement du bâtiment ou de l'immeuble.However, such a suction device, comprising suction hoods at a fixed position on a given level of the building, requires the installation of sub-collectors over a great length, on the horizontal plane of each level of the building. This installation is carried out during the construction and layout of the building or building.

De plus, le nombre important de bouches d'aspiration implique un plus grand risque d'obturation ou de fuite. En outre, toute réparation ou tout entretien des sous-collecteurs et de leurs bouches d'aspiration entraîne un démontage partiel de l'installation par niveau, ce qui est long et peu pratique.In addition, the large number of suction outlets implies a greater risk of blockage or leakage. In addition, any repair or maintenance of the sub-collectors and their suction outlets leads to a partial dismantling of the installation by level, which is long and inconvenient.

Par ailleurs, un tel dispositif d'aspiration nécessite beaucoup de manipulations pour l'utilisateur, qui doit brancher et débrancher le tuyau flexible sur les différentes bouches au fur et à mesure du nettoyage des portions de surface par aspiration. De surcroît, ce dispositif d'aspiration oblige l'utilisateur à évoluer dans un rayon de travail limité lorsque le tuyau flexible est branché sur une bouche d'aspiration d'un sous-collecteur donné.Furthermore, such a suction device requires a lot of manipulation for the user, who must connect and disconnect the flexible hose on the various mouths as and when cleaning the surface portions by suction. In addition, this suction device forces the user to move within a limited working radius when the flexible hose is connected to a suction mouth of a given sub-collector.

La présente invention a pour objet de pallier l'ensemble des inconvénients précités dans le cas d'un dispositif d'aspiration classique, en éliminant l'installation de un ou plusieurs sous-collecteurs disposés sur un même niveau d'un bâtiment, tout en permettant l'aspiration sur la totalité de la surface considérée de ce même niveau.The object of the present invention is to overcome all of the aforementioned drawbacks in the case of a conventional suction device, by eliminating the installation of one or more sub-collectors arranged on the same level of a building, while allowing aspiration on the entire surface considered of this same level.

Le dispositif d'aspiration, selon l'invention, remplit une fonction identique à un dispositif d'aspiration traditionnel et permet, en outre, de créer une bouche d'aspiration fictive qui est mobile à tout endroit quelconque du niveau du bâtiment.The suction device according to the invention fulfills a function identical to a traditional suction device and also makes it possible to create a fictitious suction mouth which is movable at any location on the level of the building.

La solution conforme à la présente invention, pour résoudre ce problème technique, consiste en un dispositif d'aspiration utilisable sur au moins un niveau d'un bâtiment, du type comportant une buse d'aspiration tenue à la main et reliée par un tuyau flexible à une conduite d'aspiration elle-même reliée à un collecteur d'aspiration centralisée, caractérisé en ce qu'au moins la conduite d'aspiration est enroulable de préférence automatiquement sur un dispositif enrouleur mobile monté sur un véhicule et entraîné par le déplacement de ce dernier, la conduite d'aspiration étant déconnectable dudit collecteur.The solution according to the present invention, to solve this technical problem, consists of a suction device usable on at least one level of a building, of the type comprising a suction nozzle held in the hand and connected by a flexible hose. to a suction pipe itself connected to a centralized suction manifold, characterized in that at least the suction pipe is preferably automatically windable on a mobile winder device mounted on a vehicle and driven by the movement of the latter, the suction line being disconnectable from said manifold.

Au moyen d'un tel dispositif enrouleur mobile, où s'enroule automatiquement la conduite d'aspiration qui elle-même est reliée à un collecteur d'aspiration centralisée, une bouche d'aspiration mobile est alors créée.By means of such a mobile winding device, where the suction line is automatically wound up, which itself is connected to a centralized suction manifold, a mobile suction mouth is then created.

Ce dispositif d'aspiration, de par sa mobilité, permet de réaliser l'aspiration sur la totalité de la surface du niveau concerné sans aucune opération de branchement et débranchement du tuyau flexible sur la conduite d'aspiration. Par conséquent, tous les problèmes existant avec les dispositifs d'aspiration antérieurement connus sont supprimés.This suction device, due to its mobility, makes it possible to perform suction on the entire surface of the level concerned without any operation of connection and disconnection of the flexible pipe on the suction pipe. Consequently, all the problems existing with the previously known suction devices are eliminated.

Selon une autre caractéristique avantageuse, le dispositif enrouleur précité est entraîné par le déplacement manuel du véhicule.According to another advantageous characteristic, the aforementioned winding device is driven by the manual movement of the vehicle.

Selon une autre caractéristique avantageuse, le tuyau flexible est lui même enroulable, de préférence automatiquement, sur un autre dispositif enrouleur associé au premier.According to another advantageous characteristic, the flexible pipe is itself windable, preferably automatically, on another winding device associated with the first.

Selon une caractéristique avantageuse, chaque dispositif enrouleur comprend un tambour rotatif de préférence cylindrique à axe vertical, et un moyen de guidage automatique d'enroulement du tuyau flexible ou de la conduite d'aspiration sur le tambour.According to an advantageous characteristic, each winding device comprises a rotary drum, preferably cylindrical with a vertical axis, and means for automatically guiding the winding of the flexible pipe or of the suction line on the drum.

Selon toujours une autre caractéristique avantageuse, le véhicule précité est un chariot sur lequel est monté chaque dispositif enrouleur et le mouvement d'un tambour associé est asservi à la rotation d'au moins une roue porteuse ou menante dudit chariot, de préférence, de façon sélectivement débrayable.According to another advantageous characteristic, the aforementioned vehicle is a carriage on which each winding device is mounted and the movement of an associated drum is controlled by the rotation of at least one carrying or driving wheel of said carriage, preferably so selectively disengageable.

Selon un second mode de réalisation, le dispositif d'aspiration utilisable sur au moins un niveau d'un bâtiment, est caractérisé en ce qu'il comprend au moins un moteur électrique d'entraînement d'une roue motrice du véhicule commandé par des moyens de commande, de préférence à bouton-poussoirs, et en ce que le dispositif enrouleur précité de la conduite d'aspiration est entraîné par un moteur électrique, également commandé par les moyens de commande, d'une manière telle que la vitesse d'enroulement ou de déroulement de la conduite d'aspiration soit en relation avec la vitesse de déplacement du véhicule.According to a second embodiment, the suction device usable on at least one level of a building, is characterized in that it comprises at least one electric motor for driving a driving wheel of the vehicle controlled by means control, preferably push-button, and in that the aforementioned winding device of the suction line is driven by an electric motor, also controlled by the control means, in such a way that the winding speed or the progress of the suction line is related to the speed of movement of the vehicle.

Selon une autre caractéristique du second mode de réalisation, le dispositif comprend deux moyens de commande, l'un pour commander le moteur électrique d'entraînement du véhicule dans un sens de rotation de marche vers l'avant du véhicule et pour commander simultanément le moteur électrique d'entraînement du dispositif enrouleur dans un sens de rotation de déroulement de la conduite d'aspiration, l'autre, pour commander le moteur electrique d'entraînement du véhicule dans un sens de rotation de marche vers l'arrière du véhicule et pour commander simultanément le moteur électrique d'entraînement du dispositif enrouleur dans le sens de rotation d'enroulement de la conduite d'aspiration.According to another characteristic of the second embodiment, the device comprises two control means, one for controlling the electric motor driving the vehicle in a direction of rotation of forward travel of the vehicle and for simultaneously controlling the motor. electric drive of the winding device in a direction of rotation of unwinding of the suction line, the other, to control the electric motor for driving the vehicle in a direction of rotation towards the rear of the vehicle and for simultaneously controlling the electric motor for driving the take-up device in the direction of rotation for winding the suction line.

Selon toujours une autre caractéristique avantageuse de ce second mode de réalisation, le dispositif comprend un moteur électrique commandé par un moyen de commande de préférence à bouton-poussoir, et assurant l'entraînement du dispositif enrouleur du tuyau flexible dans le sens d'enroulement.According to still another advantageous characteristic of this second embodiment, the device comprises an electric motor controlled by a control means preferably with a push button, and ensuring the drive of the hose reel device in the winding direction.

En référence à la figure 1, le dispositif d'aspiration, manoeuvrable manuellement, est situé sur un niveau 1 d'un bâtiment. Ce dispositif est mobile sur toute la surface du niveau 1 et est relié à une installation fixe dans le bâtiment.Referring to Figure 1, the suction device, manually operable, is located on a level 1 of a building. This device is mobile over the entire surface of level 1 and is connected to a fixed installation in the building.

L'installation fixe comprend un collecteur vertical 2 d'aspiration centralisée, qui s'étend sensiblement sur la hauteur du bâtiment, nécessaire pour desservir tous les niveaux de celui-ci, et une installation d'aspiration classique 3 qui est située en sous-sol du bâtiment, et sur laquelle est fixé le collecteur vertical 2. Ce collecteur 2 comporte une bouche d'aspiration 4 à chaque niveau ou étage du bâtiment.The fixed installation comprises a vertical collector 2 of centralized suction, which extends substantially over the height of the building, necessary to serve all the levels thereof, and a conventional suction installation 3 which is located below building floor, and to which the vertical collector 2 is fixed. This collector 2 has a suction mouth 4 on each level or floor of the building.

Le dispositif d'aspiration selon l'invention se présente sous la forme d'un véhicule 5 déplaçable manuellement.The suction device according to the invention is in the form of a vehicle 5 which can be moved manually.

Il comporte une buse d'aspiration 6 tenue à la main et reliée par un tuyau flexible 7 à une conduite d'aspiration 8. Cette dernière est elle-même reliée au collecteur vertical 2 d'aspiration centralisée, par l'intermédiaire de la bouche d'aspiration 4.It comprises a suction nozzle 6 held in the hand and connected by a flexible pipe 7 to a suction pipe 8. The latter is itself connected to the vertical collector 2 of centralized suction, via the mouth suction 4.

La buse d'aspiration 6 peut être équipée à son extrémité libre d'un capteur de sol 9 ou de divers accessoires tels que des suceurs ou des brosses.The suction nozzle 6 can be equipped at its free end with a soil sensor 9 or with various accessories such as squeegees or brushes.

La conduite d'aspiration 8 est enroulable de préférence automatiquement sur un dispositif enrouleur monté sur le véhicule 5. Ainsi lors du déplacement du véhicule par étapes, en s'éloignant de la bouche d'aspiration 4, la conduite d'aspiration se déroule progressivement afin de permettre l'aspiration sur la totalité du niveau par portion de surface de celui-ci.The suction line 8 is preferably automatically windable on a winding device mounted on the vehicle 5. Thus when moving the vehicle in stages, moving away from the suction mouth 4, the suction line takes place gradually in order to allow aspiration over the entire level per portion of the surface thereof.

La conduite d'aspiration 8, déconnectable du collecteur vertical centralisé 2, est de grande longueur: par exemple entre environ 10 et 40 mètres, et de préférence entre 20 et 30 mètres. Le tuyau flexible 7 a une longueur par exemple d'environ 10 mètres. Ce dernier permet d'aspirer une portion de surface donnée et d'effectuer le nettoyage interne des bureaux ou des locaux.The suction line 8, which can be disconnected from the centralized vertical collector 2, is very long: for example between around 10 and 40 meters, and preferably between 20 and 30 meters. The flexible pipe 7 has a length for example of around 10 meters. The latter makes it possible to vacuum a given portion of surface and to carry out internal cleaning of offices or premises.

Le véhicule déplaçable manuellement peut être roulant tel qu'un chariot ou glissant tel qu'un traîneau.The manually movable vehicle can be rolling such as a cart or sliding such as a sled.

La figure 2 représente le dispositif d'aspiration mobile selon l'invention, se présentant sous la forme d'un chariot.Figure 2 shows the mobile suction device according to the invention, in the form of a carriage.

Comme le montre la figure 2, le chariot comporte deux tambours cylindriques 10 et 11 qui sont chacun à axe vertical 12 et 13 et supportés sur un châssis 14 de préférence muni d'une garniture destinée à amortir les chocs et qui ne laisse pas de trace lorsque le véhicule heurte les murs du bâtiment. En référence à la figure 4, des montants verticaux 15 relient le châssis 14 à une poignée de préférence tubulaire 16 qui entoure les deux tambours 10 et 11. Quand le dispositif d'aspiration ne fonctionne pas, la poignée tubulaire 16 peut recevoir la buse d'aspiration 6, ce qui facilite le rangement du dispositif.As shown in Figure 2, the carriage comprises two cylindrical drums 10 and 11 which are each with a vertical axis 12 and 13 and supported on a chassis 14 preferably provided with a lining intended to absorb shocks and which leaves no trace when the vehicle hits the walls of the building. Referring to Figure 4, vertical uprights 15 connect the frame 14 to a preferably tubular handle 16 which surrounds the two drums 10 and 11. When the suction device does not work, the tubular handle 16 can receive the nozzle d suction 6, which facilitates the storage of the device.

Le châssis est équipé de cinq roues. Deux paires de roues porteuses 17 et 18 sont situées respectivement aux extrémités opposées du châssis 14. Ces roues 17 et 18 sont avantageusement orientables. Par ailleurs, une roue menante 19 roulant sur le sol 1 est située sous la partie médiane du châssis 14 et n'est pas orientable mais a son axe perpendiculaire à la direction longitudinale du châssis 14.The chassis is equipped with five wheels. Two pairs of supporting wheels 17 and 18 are located respectively at the opposite ends of the chassis 14. These wheels 17 and 18 are advantageously orientable. Furthermore, a driving wheel 19 rolling on the ground 1 is situated under the middle part of the chassis 14 and is not orientable but has its axis perpendicular to the longitudinal direction of the chassis 14.

Ainsi, l'utilisateur peut déplacer le chariot manuellement, par traction ou en le poussant, au moyen de la poignée tubulaire 16.Thus, the user can move the carriage manually, by pulling or pushing it, by means of the tubular handle 16.

En référence aux figures 2, 3 et 4, le dispositif enrouleur sur lequel est enroulée la conduite d'aspiration 8, comprend en outre le tambour rotatif 10 à axe vertical 12, une barre 20 parallèle à l'axe 12 du tambour 10. Cette barre 20 est positionnée sur le châssis 14 du dispositif d'aspiration en fonction du diamètre d'enroulement de la conduite d'aspiration 8 et est extérieurement espacée de la paroi latérale 22 du tambour 10. La barre verticale 20 est munie d'un galet rotatif fou 24 de guidage de la conduite d'aspiration 8. Ce galet 24 est monté librement coulissant sur la barre verticale 20. La conduite d'aspiration est alors enroulée en hélice en au moins une couche, notamment à spires jointives, autour du tambour 10, tout en étant guidée par le galet 24 qui coulisse vers le haut ou vers le bas de la barre 20 suivant l'enroulement ou le déroulement de la conduite d'aspiration 8. Pour faciliter l'enroulement de la conduite d'aspiration, le tambour 10 peut comporter, dans sa partie basse, une rainure hélicoïdale. Cette dernière permet de bien amorcer l'enroulement en hélice de la conduite d'aspiration 8.Referring to Figures 2, 3 and 4, the winding device on which is wound the suction line 8, further comprises the rotary drum 10 with vertical axis 12, a bar 20 parallel to the axis 12 of the drum 10. This bar 20 is positioned on the frame 14 of the suction device as a function of the winding diameter of the suction pipe 8 and is externally spaced from the side wall 22 of the drum 10. The vertical bar 20 is provided with a roller idler rotary 24 for guiding the suction pipe 8. This roller 24 is mounted to slide freely on the vertical bar 20. The suction pipe is then helically wound in at least one layer, in particular with contiguous turns, around the drum 10, while being guided by the roller 24 which slides up or down the bar 20 depending on the winding or unwinding of the suction line 8. To facilitate the winding of the suction line, the drum 10 may include, in its lower part, a helical groove. The latter makes it possible to properly initiate the helical winding of the suction line 8.

Par ailleurs, le mouvement du tambour 10 est commandé par la rotation de la roue menante 19. Plus précisément, le tambour 10 est entraîné par la roue 19 du chariot par l'intermédiaire d'un système de transmission à friction qui se compose comme suit : une roue menée de friction 26, entraînée par la roue menante 19 tournant en roulant au sol, est en contact frottant avec un plateau ou une couronne 27 formant la base du tambour 10. L'entraînement de la roue menée 26 par la roue 19 se fait au moyen d'une transmission comprenant une courroie 28 passant sur deux poulies 26 et 30 coaxialement solidaires respectivement des roues 19 et 26.Furthermore, the movement of the drum 10 is controlled by the rotation of the driving wheel 19. More specifically, the drum 10 is driven by the wheel 19 of the carriage by means of a friction transmission system which is composed as follows : a driven friction wheel 26, driven by the driving wheel 19 rotating while rolling on the ground, is in friction contact with a plate or a crown 27 forming the base of the drum 10. The driving of the driven wheel 26 by the wheel 19 is done by means of a transmission comprising a belt 28 passing over two pulleys 26 and 30 coaxially integral respectively with the wheels 19 and 26.

Ce système de transmission est sélectivement embrayable ou débrayable respectivement par mise en tension et détente de la courroie de transmission 28. La mise en tension provoquant l'entraînement de la roue menée 26 tandis que la détente de la courroie 28 provoque le glissement de celle-ci sur les poulies 29 et 30 de façon que la roue menée 26 ne soit pas entraînée. Le dispositif tendeur et détendeur comprend un palonnier 31 monté basculant en un point intermédiaire sur un axe horizontal 32 et dont une extrémité, située au voisinage du brin supérieur ou inférieur de la courroie 28, par exemple au-dessus du brin supérieur, porte un galet 33, rouleau ou patin susceptible, par basculement du palonnier dans un sens ou dans le sens contraire, de s'écarter dudit brin pour détendre la courroie 28 ou de venir en contact et d'appuyer sur ledit brin pour tendre la courroie 28. La commande du palonnier 31 peut être manuelle ou de préférence au moyen d'une pédale 34 portée par l'extrémité d'un levier coudé 35 basculant monté en un point intermédiaire sur un axe horizontal 36 et dont l'autre extrémité est reliée mobilement à l'extrémité libre du palonnier 31. A cet effet, l'extrémité du levier 35 coulisse dans une glissière de guidage 37 solidaire du palonnier 31.This transmission system is selectively clutchable or disengageable respectively by tensioning and relaxing the transmission belt 28. The tensioning causing the driving of the driven wheel 26 while the relaxation of the belt 28 causes the sliding thereof. ci on the pulleys 29 and 30 so that the driven wheel 26 is not driven. The tensioner and regulator device comprises a lifter 31 mounted tilting at an intermediate point on a horizontal axis 32 and one end of which, located in the vicinity of the upper or lower strand of the belt 28, for example above the upper strand, carries a roller 33, roller or shoe capable, by tilting the lifter in one direction or in the opposite direction, to move away from said strand to relax the belt 28 or to come into contact and to press on said strand to tension the belt 28. The control of the spreader 31 can be manual or preferably by means of a pedal 34 carried by the end of a tilting bent lever 35 mounted at an intermediate point on a horizontal axis 36 and the other end of which is movably connected to the free end of the lifter 31. To this end, the end of the lever 35 slides in a guide slide 37 secured to the lifter 31.

Pour embrayer, l'opérateur appuit sur la pédale 34 par son pied pour l'abaisser dans la position représentée en trait plein. Cet abaissement fait pivoter le palonnier 31 dans le sens de rotation inverse des aiguilles d'une montre sur la figure 2 de manière que le galet 33, rouleau ou patin, vienne appuyer sur la courroie 28 de façon à la tendre suffisamment pour entraîner la roue menée 26. Dans cette position embrayée, le bras de levier 35 coudé, de préférence, en équerre, sera en position sensiblement verticale de sorte que son extrémité supérieure 38 constitue un point mort haut bloquant ainsi le palonnier 31 dans sa position tendeuse. Pour débrayer le système d'entraînement, l'opérateur relève la pédale 34 depuis la position sensiblement horizontale basse vers le haut jusqu'à la position extrême haute représentée en pointillé sur la figure 2 en faisant ainsi basculer le palonnier 31 dans le sens de rotation des aiguilles d'une montre, ce qui détend la courroie 28 en provoquant son glissement sur les poulies 29 et 30.To engage, the operator presses on the pedal 34 with his foot to lower it to the position shown in solid lines. This lowering causes the lifter 31 to pivot in the opposite direction of clockwise rotation in FIG. 2 so that the roller 33, roller or shoe, comes to press on the belt 28 so as to tension it sufficiently to drive the wheel. driven 26. In this engaged position, the lever arm 35 bent, preferably at right angles, will be in a substantially vertical position so that its upper end 38 constitutes a top dead center thus blocking the lifter 31 in its tensioning position. To disengage the drive system, the operator raises the pedal 34 from the substantially horizontal low position upwards to the extreme high position shown in dotted lines in FIG. 2, thereby causing the lifter 31 to tilt in the direction of rotation. clockwise, which relaxes the belt 28 by causing it to slide on the pulleys 29 and 30.

Selon une variante de réalisation, le système de transmission par friction peut être remplacé par un système de transmission à entraînement positif par engrenages ou par un système de poulies et de courroies ou de chaînes, avec dispositif de débrayage associé.According to an alternative embodiment, the friction transmission system can be replaced by a positive drive transmission system by gears or by a system of pulleys and belts or chains, with associated declutching device.

En référence aux figures 2, 3 et 4, l'autre dispositif enrouleur sur lequel est enroulé le tuyau flexible 7, comprend le tambour rotatif 11 à axe vertical 13 et une barre 21 parallèle à l'axe 13 du tambour 11. De façon similaire au premier dispositif enrouleur, cette barre 21 est positionnée sur le châssis 14 du chariot en fonction du diamètre d'enroulement du tuyau flexible 7 et est extérieurement espacée de la paroi latérale 23 du tambour 11. La barre verticale 21 est également munie d'un galet rotatif fou 25 de guidage du tuyau flexible 7. Ce galet 25 est monté librement coulissant sur la barre verticale 21. Le tuyau flexible est enroulé en hélice en au moins une couche, notamment à spires jointives, autour du tambour 11. Le galet 25 tout en coulissant le long de la barre verticale 21, permet de guider l'enroulement ou le déroulement du tuyau flexible 7. De même ici, pour faciliter l'enroulement du tuyau flexible, le tambour 11 peut comporter, dans sa partie basse, une rainure hélicoïdale qui sert à amorcer l'enroulement en hélice du tuyau flexible 7.With reference to FIGS. 2, 3 and 4, the other winding device on which the flexible pipe 7 is wound, comprises the rotary drum 11 with a vertical axis 13 and a bar 21 parallel to the axis 13 of the drum 11. Similarly at the first winding device, this bar 21 is positioned on the chassis 14 of the carriage as a function of the winding diameter of the flexible pipe 7 and is externally spaced from the side wall 23 of the drum 11. The vertical bar 21 is also provided with a idler rotary roller 25 for guiding the flexible pipe 7. This roller 25 is mounted to slide freely on the vertical bar 21. The flexible pipe is wound helically in at least one layer, in particular with contiguous turns, around the drum 11. The roller 25 while sliding along the vertical bar 21, makes it possible to guide the winding or unwinding of the flexible pipe 7. Similarly here, to facilitate the winding of the flexible pipe, the drum 11 may include, in its lower part e, a helical groove which serves to initiate the helical winding of the flexible pipe 7.

En référence à la figure 4, ce dispositif enrouleur comporte des moyens de blocage, déblocables, de la mise en rotation du tambour 11. Ces moyens de blocage se présentent sous la forme d'un frein auto- bloquant qui est constitué d'un patin 39 qui vient en contact frottant avec le plateau 40 formant la base du tambour 11. Un levier basculant 41 est monté sur un pivot horizontal 42 et comporte à l'une de ses extrémités, le patin 39 assurant le freinage par contact de friction du plateau 40, et, à son extrémité opposée, une pédale 43. En outre, le système de blocage comprend un ressort de rappel 44 agissant sur le levier 41 pour le solliciter constamment vers la position de freinage (contact du patin 43 avec le plateau 40 du tambour 11). En abaissant la pédale 43, le patin 39 s'écarte du plateau 40 du tambour 11. Le tambour 11 est alors débloqué et libre en rotation pour le déroulement du tuyau flexible 7. Lorsqu'il n'est exercée aucune traction sur le tuyau flexible 7, le frein est appliqué en permanence. Le tambour 11 est donc bloqué automatiquement lorsque l'utilisateur aspire au moyen du tuyau flexible 7 déroulé partiellement. Quand l'utilisateur déroule le tuyau flexible 7 par simple traction, le frein se débloque alors automatiquement par basculement du levier 41 dans le sens de rotation des aiguilles d'une montre sur la figure 4 et toute amorce de rotation intempestive du tambour 11 dans le sens d'enroulement provoque le blocage automatique du tambour 11 par application du frein.With reference to FIG. 4, this winding device comprises unlockable locking means for rotating the drum 11. These locking means are in the form of a self-locking brake which consists of a pad 39 which comes into rubbing contact with the plate 40 forming the base of the drum 11. A rocking lever 41 is mounted on a horizontal pivot 42 and comprises at one of its ends, the pad 39 ensuring braking by friction contact of the plate 40, and, at its opposite end, a pedal 43. In addition, the blocking system comprises a return spring 44 acting on the lever 41 to constantly urge it towards the braking position (contact of the pad 43 with the plate 40 of the drum 11). By lowering the pedal 43, the shoe 39 moves away from the plate 40 of the drum 11. The drum 11 is then released and free to rotate for the unwinding of the flexible pipe 7. When no traction is exerted on the flexible pipe 7, the brake is applied continuously. The drum 11 is therefore blocked automatically when the user sucks in by means of the flexible hose 7 partially unwound. When the user unrolls the flexible pipe 7 by simple pull, the brake is then released automatically by tilting the lever 41 in the direction of rotation of the needles of a watch in FIG. 4 and any untimely initiation of rotation of the drum 11 in the winding direction causes the automatic blocking of the drum 11 by applying the brake.

Par ailleurs, en référence à la figure 2, ce même dispositif enrouleur comporte un organe élastique de rappel assurant l'entraînement automatique du tambour 11 dans le sens d'enroulement. Le système de rappel est constitué d'une part d'une poupée 45 coaxialement solidaire du plateau 40 du tambour rotatif 11, et d'autre part d'un cordon élastique 46 simple ou multiple (du type "Sandow") relativement long, dont une extrémité est attachée à la poupée 45 en un point d'attache 47 et dont l'autre extrémité est fixée au châssis du chariot après être passée une ou plusieurs fois sur quatre poulies folles 48 montées respectivement aux quatre coins du châssis 14 sur des axes 49 sensiblement parallèles à l'axe 12 du tambour 11.Furthermore, with reference to FIG. 2, this same winding device comprises an elastic return member ensuring the automatic driving of the drum 11 in the winding direction. The return system consists on the one hand of a doll 45 coaxially integral with the plate 40 of the rotary drum 11, and on the other hand of a relatively long elastic cord 46 simple or multiple (of the "Sandow" type), of which one end is attached to the headstock 45 at an attachment point 47 and the other end of which is fixed to the chassis of the carriage after having passed one or more times over four idler pulleys 48 mounted respectively at the four corners of the chassis 14 on axes 49 substantially parallel to the axis 12 of the drum 11.

En référence au schéma réprésenté à la figure 5, le cordon 46 passe autour des quatre poulies 48 (cordon représenté en trait plein). Selon une variante de réalisation, le cordon 46 passe autour de trois poulies (cordon représenté en trait "mixte" ou en trait "interrompu"). Suivant la figure 5, le fonctionnement du système de rappel est le suivant. Lorsque le tuyau flexible 7 est enroulé sur le tambour 11, le cordon 46 est en position détendue, c'est-à-dire qu'il subit uniquement une pré-contrainte initiale. Dès que l'opérateur déroule manuellement le tuyau flexible 7, par simple traction, dans le sens de la flèche sur la figure 5, le tambour 11 est entraîné en rotation dans le sens inverse des aiguilles d'une montre sur la figure 5. De ce fait, la poupée 45 est également entraînée solidairement dans le même sens, ce qui provoque l'enroulement du cordon 46 sur cette poupée 45. Ainsi, le cordon 46 se tend en provoquant une réaction élastique de rappel dudit cordon en sens inverse sur le tambour 11. Puis, lorsque l'opérateur abaisse la pédale 43 représentée à la figure 4 (le patin 39 s'écartant du plateau 40), le tambour 11 est libéré et entraîné automatiquement dans le sens d'enroulement par la détente du cordon élastique 46. Le tuyau flexible 7 s'enroule alors automatiquement sur le tambour 11.Referring to the diagram shown in Figure 5, the cord 46 passes around the four pulleys 48 (cord shown in solid lines). According to an alternative embodiment, the cord 46 passes around three pulleys (cord shown in "mixed" line or in "broken" line). According to Figure 5, the operation of the reminder system is as follows. When the flexible pipe 7 is wound on the drum 11, the cord 46 is in the relaxed position, that is to say that it undergoes only an initial pre-stress. As soon as the operator manually unrolls the flexible pipe 7, by simple pulling, in the direction of the arrow in FIG. 5, the drum 11 is rotated in an anticlockwise direction in FIG. 5. From this fact, the doll 45 is also driven integrally in the same direction, which causes the winding of the cord 46 on this doll 45. Thus, the cord 46 is stretched by causing an elastic reaction of return of said cord in the opposite direction on the drum 11. Then, when the operator lowers the pedal 43 shown in FIG. 4 (the pad 39 moving away from the plate 40), the drum 11 is released and driven automatically in the winding direction by the relaxation of the elastic cord 46. The flexible pipe 7 is then automatically wound up on the drum 11.

Selon une variante de réalisation, l'organe élastique de rappel peut être sous la forme d'un ressort de rappel.According to an alternative embodiment, the elastic return member may be in the form of a return spring.

En réference aux figures 2 et 3, le tuyau flexible 7 est relié à la conduite d'aspiration 8 par un tube de liaison 50 qui comporte des joints tournants 51 et 52 étanches à la dépression. Ces joints tournants 51 et 52 sont respectivement coaxiaux des axes verticaux 12 et 13 de rotation des tambours cylindriques 10 et 11.With reference to FIGS. 2 and 3, the flexible pipe 7 is connected to the suction pipe 8 by a connection tube 50 which includes rotary joints 51 and 52 which are vacuum tight. These rotary joints 51 and 52 are respectively coaxial with the vertical axes 12 and 13 of rotation of the cylindrical drums 10 and 11.

Les tambours cylindriques 10 et 11 sont creux. Leurs volumes intérieurs 53 et 54 constituent des espaces de rangement d'ustensiles de nettoyage et/ou d'aspiration tels que capteurs de sol, brosses, chiffons, produits d'entretien et autres. Ces volumes peuvent également constituer un espace de rangement d'un sac poubelle dans lequel l'utilisateur déversera par exemple les contenus des corbeilles de bureaux.The cylindrical drums 10 and 11 are hollow. Their interior volumes 53 and 54 constitute storage spaces for cleaning and / or suction utensils such as floor sensors, brushes, rags, cleaning products and others. These volumes can also constitute a storage space for a garbage bag into which the user will pour, for example, the contents of the office baskets.

Suivant les figures 1 à 5, le fonctionnement du dispositif d'aspiration utilisable sur au moins un niveau est le suivant.According to Figures 1 to 5, the operation of the suction device usable on at least one level is as follows.

Dans un premier temps, l'utilisateur met en place le chariot mobile 5 sur un niveau 1 donné du bâtiment. Il branche alors l'extrémité libre de la conduite d'aspiration 8 sur la bouche d'aspiration 4 qui est disposée sur le collecteur vertical d'aspiration centralisée.First, the user sets up the mobile carriage 5 on a given level 1 of the building. It then connects the free end of the suction pipe 8 to the suction mouth 4 which is arranged on the vertical centralized suction manifold.

Puis, en fonction de la portion de surface que l'utilisateur désire aspirer, le chariot 5 est déplacé manuellement à l'aide de la poignée tubulaire 16. Or, le déplacement du chariot 5 s'opère par translation de l'ensemble du dispositif d'aspiration. Un tel déplacement entraîne, au moyen du système de transmission par friction, la rotation du tambour 10 sur lequel est enroulée la conduite d'aspiration 8. Ainsi, la conduite d'aspiration 8 se déroule sans traction par tronçon rectiligne relativement au déplacement du chariot.Then, depending on the portion of the surface that the user wishes to vacuum, the carriage 5 is moved manually using the tubular handle 16. However, the movement of the carriage 5 takes place by translation of the entire device suction. Such a displacement causes, by means of the friction transmission system, the rotation of the drum 10 on which the suction pipe 8 is wound. Thus, the suction pipe 8 takes place without traction by straight section relative to the movement of the carriage .

L'enroulement de la conduite d'aspiration 8 s'effectue suivant le même principe.The winding of the suction line 8 is carried out according to the same principle.

Il est également possible de déplacer le chariot 5 sans entraîner en rotation le tambour 10, c'est-à-dire sans provoquer le déroulement ou l'enroulement de la conduite d'aspiration 8. Il suffit alors de relever la pédale 34 pour débrayer le système de transmission.It is also possible to move the carriage 5 without rotating the drum 10, that is to say without causing the unwinding or winding of the suction line 8. It is then enough to raise the pedal 34 to disengage the transmission system.

Ce dispositif de débrayage permet à l'utilisateur de changer de niveau ou d'étage, ou encore de ranger l'appareil après l'avoir débranché de la bouche d'aspiration 4 du collecteur vertical d'aspiration centralisée 2.This declutching device allows the user to change level or stage, or even to store the device after having disconnected it from the suction mouth 4 of the vertical central suction manifold 2.

Dans un second temps, une fois que l'utilisateur a choisi la portion de surface qu'il désirait aspirée, il laisse le chariot en position d'arrêt et déroule alors manuellement le tuyau flexible 7 qui est enroulé sur le tambour 11. Le déroulement se fait manuellement en tirant simplement l'extrémité libre du tuyau flexible 7.In a second step, once the user has chosen the portion of surface he wishes to vacuum, he leaves the carriage in the stopped position and then manually unrolls the flexible pipe 7 which is wound on the drum 11. The unwinding is done manually by simply pulling the free end of the flexible pipe 7.

Lorsque l'utilisateur a déroulé une longueur suffisante du tuyau flexible 7, le frein se met en action automatiquement. Ainsi, l'utilisateur peut travailler dans un rayon donné.When the user has unwound a sufficient length of flexible hose 7, the brake is applied automatically. Thus, the user can work within a given radius.

L'aspiration est effectuée avantageusement lorsque le tuyau flexible 7 est equipé à son extrémité d'une buse d'aspiration 6 prolongée d'un capteur de sol.The suction is advantageously carried out when the flexible pipe 7 is equipped at its end with a suction nozzle 6 extended by a soil sensor.

Lorsque l'utilisateur a terminé l'aspiration d'une portion de surface, il débloque le frein autoblo- quant, en appuyant sur la pédale 43 qui provoque la détente de l'organe élastique de rappel, ce qui entraîne l'enroulement automatique du tuyau flexible 7 par rotation du tambour 11, avant de déplacer le chariot mobile 5.When the user has finished sucking up a portion of the surface, he releases the self-locking brake, by pressing on the pedal 43 which causes the elastic return member to relax, which causes the automatic winding of the flexible pipe 7 by rotation of the drum 11, before moving the mobile carriage 5.

Les figures 6 et 7 illustrent le second mode de réalisation du dispositif selon l'invention qui diffère du premier mode de réalisation par le fait que le véhicule 5 et les deux dispositifs enrouleur sont entrai- nés par des moteurs électriques à la manière décrite ci-dessous. Les éléments identiques à ces deux modes de réalisation portent les mêmes références et ne seront pas décrits de nouveau.FIGS. 6 and 7 illustrate the second embodiment of the device according to the invention which differs from the first embodiment in that the vehicle 5 and the two winding devices are driven by electric motors in the manner described above. below. The elements identical to these two embodiments bear the same references and will not be described again.

Le dispositif suivant le second mode de réalisation comprend de préférence deux moteurs électriques 55 et 56 à courant continu et à réducteurs de vitesse solidaires du châssis 14 et disposés symétriquement de part et d'autre de l'axe longitudinal du véhicule. Chaque moto-réducteur 55, 56 entraîne par l'intermédiaire par exemple d'une roue à friction 57, une roue motrice 55a, 56a du véhicule. Cette transmission peut également se faire par un système de transmission à entraînement positif par engrenages, courroies ou chaînes.The device according to the second embodiment preferably comprises two electric motors 55 and 56 with direct current and with speed reducers integral with the chassis 14 and arranged symmetrically on either side of the longitudinal axis of the vehicle. Each geared motor 55, 56 drives, for example via a friction wheel 57, a driving wheel 55a, 56a of the vehicle. This transmission can also be done by a positive drive transmission system by gears, belts or chains.

Le dispositif comprend de plus un moteur électrique à courant continu 58 d'entraînement du tambour 10 autour duquel est enroulée la conduite d'aspiration 8. Ce moteur est relie au tambour 10 par l'intermédiaire, par exemple d'une roue à friction 59 solidaire de l'arbre d'entraînement du moteur, et en contact par exemple frottant avec le plateau 27 formant base du tambour 10. Le moteur 58 est fixé sur une plaque inclinée 60 solidaire du châssis 14 et à angle d'inclinaison réglable de façon à modérer la force de contact de la roue à friction 59 sous le plateau 27. La transmission du moteur 58 au tambour 10 peut également se faire par un système de transmission à entraînement positif par engrenages, courroies ou chaînes.The device further comprises a direct current electric motor 58 for driving the drum 10 around which the suction pipe 8 is wound. This motor is connected to the drum 10 via, for example a friction wheel 59 integral with the motor drive shaft, and in con tact for example rubbing with the plate 27 forming the base of the drum 10. The motor 58 is fixed to an inclined plate 60 integral with the chassis 14 and at an adjustable angle of inclination so as to moderate the contact force of the friction wheel 59 under the plate 27. The transmission from the motor 58 to the drum 10 can also be done by a positive drive transmission system by gears, belts or chains.

Avantageusement, les moteurs électriques 55, 56; 58 sont commandés simultanément par deux organes de commande 61 et 62 de préférence à deux bouton-poussoirs, l'un 61 mettant en service les moteurs 55, 56; 58 de façon à entraîner la roue motrice 55a, 56a dans un sens correspondant au déplacement vers l'avant du véhicule c'est-à-dire d'éloignement de celui-ci de la bouche d'aspiration 4 et de façon à entraîner le tambour 10 dans le sens de déroulement de la conduite d'aspiration 8, l'autre 62 mettant en service les moteurs 55, 56; 58 de façon à entraîner la roue motrice 55a, 56a dans un sens contraire correspondant au déplacement vers l'arrière du véhicule c'est-à-dire de rapprochement de celui-ci vers la bouche d'aspiration 4 et de façon à entraîner le tambour 10 dans le sens d'enroulement de la conduite d'aspiration 8. Bien entendu, les vitesses de déplacement vers l'avant ou vers l'arrière du véhicule sont en relation appropriée respectivement avec les vitesses d'enroulement et de déroulement de la conduite d'aspiration 8 sur le tambour 10.Advantageously, the electric motors 55, 56; 58 are controlled simultaneously by two control members 61 and 62 preferably with two push-buttons, one 61 putting the motors 55, 56 into service; 58 so as to drive the drive wheel 55a, 56a in a direction corresponding to the forward movement of the vehicle, that is to say, moving it away from the suction mouth 4 and so as to drive the drum 10 in the direction of unwinding of the suction line 8, the other 62 putting the motors 55, 56 into service; 58 so as to drive the drive wheel 55a, 56a in an opposite direction corresponding to the rearward movement of the vehicle, that is to say of bringing it towards the suction mouth 4 and so as to cause the drum 10 in the winding direction of the suction line 8. Of course, the forward or rearward travel speeds of the vehicle are in appropriate relation to the winding and unwinding speeds of the vehicle respectively. suction line 8 on the drum 10.

Le dispositif comprend également un organe de commande 63 de préférence a bouton-poussoir permettant de commander le moteur électrique 58 dans le sens d'enroulement de la conduite d'aspiration 8 et ce indépendamment des organes de commande 61 et 62. Ceci permet donc à l'utilisateur d'enrouler la conduite d'aspiration 8 sans mettre en service les moteurs 55 et 56.The device also comprises a control member 63 preferably with a push button enabling the electric motor 58 to be controlled in the direction of winding of the suction pipe 8 and this independently of the control members 61 and 62. This therefore allows the user to wind the suction line 8 without putting the motors 55 and 56 into service.

Le dispositif est de plus équipé d'un moteur électrique à courant continu 64, permettant l'entraînement du tambour 11 autour duquel est enroulé le tuyau flexible 7. Ce moteur est relié au tambour 11 par l'intermédiaire par exemple d'une roue à friction 65 solidaire de l'arbre d'entraînement du moteur 64 et en contact frottant avec le plateau 40 formant base du tambour 11. Le moteur 64 est également fixé sur une plaque inclinée 66 solidaire du châssis 14, et à angle d'inclinaison réglable de façon à modérer la force de contact de la roue à friction 65 sous le plateau 40. La transmission du moteur 64 au tambour 11 peut également se faire par un système de transmission à entraînement positif par engrenages, courroies ou chaînes.

This motor is connected to the drum 11 by means of, for example, a wheel. friction 65 secured to the drive shaft of the motor 64 and in rubbing contact with the plate 40 forming the base of the drum 11. The motor 64 is also fixed to an inclined plate 66 secured to the chassis 14, and with an adjustable angle of inclination so as to moderate the contact force of the friction wheel 65 under the plate 40. The transmission from the motor 64 to the drum 11 can also be done by a transmission system with positive drive by gears, belts or chains. The electric motor 64 is put into service by a control member 67 preferably with a push button to drive the drum 11 in the direction of winding of the flexible pipe 7.

Avantageusement, les organes de commande 61, 62, 63 et 67 sont logés dans une console de commande 68 solidaire de la poignée 16.Advantageously, the control members 61, 62, 63 and 67 are housed in a control console 68 secured to the handle 16.

La figure 8 représente le schéma électrique permettant à l'aide des organes de commande 61, 62, 63 et 67 de commander les moteurs 55, 56, 58 et 64, à la manière expliquée ci-dessus.FIG. 8 represents the electric diagram allowing using the control members 61, 62, 63 and 67 to control the motors 55, 56, 58 and 64, in the manner explained above.

Comme cela ressort de cette figure, l'organe de commande 61 lorsque fermé, excite des relais R1 et R2 qui ferment respectivement des groupes de contacts Ci et C2 pour alimenter les moteurs 55, 56 et 58 de façon à déplacer vers l'avant le véhicule 5 et simultanément dérouler la conduite d'aspiration 8.As can be seen from this figure, the control member 61 when closed, excites relays R 1 and R 2 which close contact groups Ci and C 2 respectively to supply the motors 55, 56 and 58 so as to move towards the 'before the vehicle 5 and simultaneously unwind the suction line 8.

De même, lorsque l'organe de commande 62 est fermé, les groupes de contacts G, C2 sont fermés pour alimenter les moteurs 55, 56 et 58 suivant une polarité inverse pour entraîner le véhicule vers l'arrière et simultanément enrouler la conduite d'aspiration 8.Similarly, when the control member 62 is closed, the contact groups G, C 2 are closed to supply the motors 55, 56 and 58 in reverse polarity to drive the vehicle to the rear and simultaneously wind the line d suction 8.

La fermeture de l'organe de commande 63 excite le relais Rs qui ouvre deux contacts Cs et C4 d'alimentation des moteurs 55 et 56 et qui ferme un contact C5 d'alimentation du moteur 58.The closure of the control member 63 excites the relay Rs which opens two contacts Cs and C 4 for supplying the motors 55 and 56 and which closes a contact C 5 for supplying the motor 58.

La fermeture de l'organe de commande 67 excite le relais R4 qui ferme les contacts Ce et C7 d'alimentation du moteur 64.Closing the control member 67 excites the relay R 4 which closes the contacts Ce and C 7 supplying the motor 64.

La figure 8 montre également la présence de contacts de relais Cs et C9 qui lorsque ouverts sous la commande d'un organe de commande de préférence par sélecteur ou interrupteur (non représenté), permettent de couper l'alimentation du moteur 58. Ceci permet de déplacer vers l'avant ou vers l'arrière le véhicule 5 sans enroulement ou déroulement conco- mittant de la conduite d'aspiration 8.FIG. 8 also shows the presence of relay contacts Cs and C 9 which, when opened under the control of a control member preferably by selector or switch (not shown), make it possible to cut the power supply to the motor 58.
