Description

La présente invention concerne une machine pour le nettoyage à sec des sols ou autres parois par aspiration qui fonctionne comme un aspirateur à sec et dont le sabot suceur est conçu pour réaliser un action mécanique sur la paroi à nettoyer.The present invention relates to a machine for dry cleaning of floors or other walls by suction which functions as a dry vacuum cleaner and whose suction shoe is designed to perform a mechanical action on the wall to be cleaned.

Les aspirateurs à sec connus comportent sur un bâti, doté d'organes de roulement et/ou de glissement, une enceinte ou cuve dans laquelle le vide est obtenu au moyen d'un ventilateur extracteur ou turbine.Known dry vacuum cleaners comprise on a frame, provided with rolling and / or sliding members, an enclosure or tank in which the vacuum is obtained by means of an extractor fan or turbine.

Un conduit d'aspiration relie un sabot suceur à l'enceinte et y déverse l'air chargé des poussières ou autres salissures.A suction duct connects a suction shoe to the enclosure and discharges the air loaded with dust or other dirt.

Dans la plupart des aspirateurs à sec connus, un réceptacle à poussières amovible ou sac, est fixé à l'intérieur de l'enceinte pour recevoir les salissures.In most of the known dry vacuum cleaners, a removable dust receptacle or bag is fixed inside the enclosure to receive the dirt.

Le sac est constitué en un matériau imperméable aux poussières et perméable à l'air.The bag is made of a material impermeable to dust and breathable.

La forme du sac est dans certains aspirateurs connus adaptée à la forme de l'enceinte en sorte que presque tout le volume interne de l'enceinte soit occupé par le sac et que ses parois se plaquent contre les parois internes de l'enceinte.The shape of the bag is in certain known vacuum cleaners adapted to the shape of the enclosure so that almost the entire internal volume of the enclosure is occupied by the bag and that its walls press against the internal walls of the enclosure.

Il a été constaté que cette disposition des aspirateurs à sec connus était génératrice d'inconvénients.It has been found that this arrangement of known dry vacuum cleaners generates drawbacks.

En effet, dans le cas où l'extraction par le ventilateur s'effectue à travers le sac, aspirateur à ventilateur sous la cuve par exemple, les parois du sac se plaquent contre les parois de la cuve et la poussière se répartit sur toute la superficie des parois du sac, ce qui freine l'aspiration.Indeed, in the case where the extraction by the fan is carried out through the bag, vacuum cleaner with fan under the tank for example, the walls of the bag are pressed against the walls of the tank and the dust is distributed over the whole surface area of the bag, which slows suction.

Cela oblige l'utilisateur à vider fréquemment l'enceinte.This forces the user to empty the enclosure frequently.

En outre, lorsque les poussières et les salissures sont humides elles peuvent colmater le sac.In addition, when the dust and dirt are wet they can clog the bag.

Le même problème se trouve dans le cas des aspirateurs à sec ou l'extraction s'effectue par le haut puisqu'il est nécessaire pour éviter que les poussières ne pénètrent dans le ventilateur et dans le moteur de disposer entre ledit ventilateur et l'enceinte un filtre qui a tendance à se boucher.The same problem is found in the case of dry vacuum cleaners where extraction is carried out from above since it is necessary to prevent dust from entering the fan and into the motor to have between said fan and the enclosure. a filter that tends to clog.

Pour remédier à cet inconvénient, il est connu sur certains types d'aspirateur à sec de disposer au niveau du déversement des poussières un dispositif du genre cyclone qui permet d'obtenir la chute au fond de l'enceinte de la plupart des poussières et salissures agglomérées ou lourdes.To overcome this drawback, it is known on certain types of dry vacuum cleaner to have at the level of the dust spillage a device of the cyclone type which makes it possible to obtain the fall to the bottom of the enclosure of most of the dust and dirt agglomerated or heavy.

Cependant, ces dispositifs sont coûteux et ont tendance à se boucher.However, these devices are expensive and tend to get clogged.

Un exemple de ce type d'aspirateur à sec est donné par le brevet US-A-3.343.199.An example of this type of dry vacuum cleaner is given by patent US-A-3,343,199.

Ce brevet décrit un aspirateur comportant une enceinte ou cuve sous laquelle est monté un groupe d'aspiration en relation avec l'intérieur de ladite enceinte.This patent describes a vacuum cleaner comprising an enclosure or tank under which is mounted a suction group in relation to the interior of said enclosure.

Un couvercle obture l'ouverture supérieure de ladite enceinte. Le déversement du flux d'air aspiré s'effectue dans l'enceinte au moyen d'un embout coudé disposé transversalement au couvercle et suivant l'axe de l'enceinte.A cover closes the upper opening of said enclosure. The discharge of the aspirated air flow takes place in the enclosure by means of a bent nozzle arranged transversely to the cover and along the axis of the enclosure.

Dans l'enceinte est disposé un réceptable ou panier perforé tronconique qui reçoit un sac en un matériau perméable à l'air.In the enclosure is arranged a receptacle or frustoconical perforated basket which receives a bag made of an air permeable material.

Les parois du réceptable tronconique sont écartés des parois internes de l'enceinte pour permettre l'aspiration.The walls of the frustoconical receptacle are spaced from the internal walls of the enclosure to allow aspiration.

Le déversement des poussières s'effectue suivant l'axe de l'enceinte en sorte que comme représenté en fig. 2 dudit brevet elles occupent l'intégralité du volume du sac et du réceptacle ce qui tend progressivement à boucher celui-ci et à freiner ou à empêcher que soit obtenue une aspiration satisfaisante.The dust is discharged along the axis of the enclosure so that, as shown in fig. 2 of said patent they occupy the entire volume of the bag and the receptacle, which gradually tends to clog the latter and to brake or prevent satisfactory suction from being obtained.

La présente invention vise à obvier à cet inconvénient à l'aide d'une combinaison de moyens particulièrement simple.The present invention aims to overcome this drawback using a particularly simple combination of means.

Un autre inconvénient des machines du type aspirateurs à sec connus à ce jour réside au niveau des organes à action mécanique sur la surface à nettoyer disposés sur le sabot suceur et destinés à détacher les salissures.Another drawback of machines of the dry vacuum cleaner type known to date resides in the organs with mechanical action on the surface to be cleaned arranged on the suction shoe and intended to loosen the dirt.

Ces organes sont généralement constitués par une ou plusieurs brosses cylindriques à axe horizontal disposées transversalement au sens d'avancement du sabot et dont une génératrice affleure le sol.These bodies generally consist of one or more cylindrical brushes with a horizontal axis arranged transversely to the direction of advancement of the shoe and of which a generator is flush with the ground.

De ce fait la surface de la brosse en contact avec le sol est trop réduite pour que soit obtenue une action mécanique efficace sur celui-ci notamment lorsque la surface du sol présente du fait de sa structure des irrégularités de niveau et le rôle de telles brosses est essentiellement de projeter les poussières et salissures vers le suceur.As a result, the surface of the brush in contact with the ground is too small for an effective mechanical action to be obtained on it, in particular when the surface of the ground presents, due to its structure, level irregularities and the role of such brushes. is essentially to throw dust and dirt towards the squeegee.

La présente invention vise également à réaliser un appareil de conception simple doté d'organes à action mécanique sur le sol qui en raison de leur conception soient réellement efficaces.The present invention also aims to provide an apparatus of simple design provided with mechanical action members on the ground which due to their design are really effective.

La présente invention vise en outre à réaliser un appareil qui soit particulièrement adapté pour réaliser le nettoyage par action mécanique et aspiration sur les sols présentant des différences de niveau comme c'est le cas de certains revêtements d'usure dont la configuration représente une succession de rainures ou creux.The present invention further aims to provide an apparatus which is particularly suitable for carrying out cleaning by mechanical action and aspiration on floors with differences in level as is the case with certain wear coatings whose configuration represents a succession of grooves or hollows.

A cet effet, la machine du type aspirateur à sec pour le nettoyage des sols et parois selon l'invention comporte un bâti doté de moyens de roulement et de manoeuvre, une enceinte d'aspiration en relation avec un groupe aspirateur définie par une cuve verticale et son couvercle, un conduit reliant l'enceinte à un sabot suceur, le conduit débouchant dans l'enceinte à sa partie supérieure par un embout coudé orienté vers le fond de l'enceinte, et un sac logé dans la cuve ayant une paroi qui intercepte le flux d'air aspiré et qui a une forme telle qu'elle reste écartée de la cuve, ladite machine étant caractérisée en ce que l'embout coudé comporte un ajutage orienté suivant une inclinaison en biais par rapport à l'axe de la cuve ou d'une de ses génératrices et tangentiellement à la paroi interne de la cuve, et en ce que le couvercle de la cuve est en forme de calotte sphérique, l'ensemble permettant d'animer le flux d'air chargé de poussières d'un mouvement tourbillonnaire qui évite leur répartition sur les parois du sac et au cours duquel les poussières les plus lourdes, par effet de cyclone, tombent au fond du sac.To this end, the machine of the dry vacuum cleaner type for cleaning floors and walls according to the invention comprises a frame provided with rolling and operating means, a suction enclosure in relation to a vacuum cleaner group defined by a vertical tank. and its cover, a conduit connecting the enclosure to a suction shoe, the conduit opening into the enclosure at its upper part by a bent end pointing towards the bottom of the enclosure, and a bag housed in the tank having a wall which intercepts the flow of aspirated air which has a shape such that it remains spaced from the tank, said machine being characterized in that the bent end piece has a nozzle oriented according to an inclination at an angle to the axis of the tank or one of its generators and tangentially to the internal wall of the tank, and in that the cover of the tank is in the form of spherical cap, the assembly allowing to animate the air flow charged with dust in a swirling movement which avoids their distribution on the walls of the bag and during which the heaviest dusts, by cyclone effect, fall to the bottom from the bag.

Suivant encore une autre caractéristique de l'invention, le sabot suceur comprend, parallèlement à une brosse transversale rotative en plan vertical, un ou plusieurs organes à action mécanique sur le sol rotatifs en plan horizontal, ce qui accroît l'action du sabot suceur sur le sol et l'efficacité de la machine selon l'invention.According to yet another characteristic of the invention, the suction shoe comprises, parallel to a transverse brush rotating in the vertical plane, one or more mechanical action members on the ground rotating in the horizontal plane, which increases the action of the suction shoe on the soil and the efficiency of the machine according to the invention.

Tel que représenté en fig. 1 à 3 la machine selon l'invention est constituée par un bâti 1 à parois latérales 2 doté d'organes de roulement 3. Sous le bâti est monté un groupe aspirateur 4.As shown in fig. 1 to 3 the machine according to the invention is constituted by a frame 1 with side walls 2 provided with rolling members 3. Under the frame is mounted a vacuum group 4.

En regard du groupe aspirateur la paroi supérieure du bâti 1 est dotée d'un orifice 5.Opposite the vacuum cleaner group, the upper wall of the frame 1 is provided with an orifice 5.

Pour fonctionner avec le sabot doté de moyens rotatifs à action mécanique sur le sol le rebord 2 du bâti est doté d'un boîtier électrique de raccordement non représenté.To operate with the shoe provided with rotary means with mechanical action on the ground, the flange 2 of the frame is provided with an electrical connection box, not shown.

Sur le bâti est fixé de préférence de manière à être amovible une enceinte constituée d'une cuve 6 et de son couvercle 7.On the frame is preferably fixed so as to be removable an enclosure consisting of a tank 6 and its cover 7.

A l'avant des côtés du caisson formé par le bâti et tout autour de celui-ci est fixé un tube 8 périphérique qui fait fonction de pare-choc et qui permet également de fixer le sabot suceur.At the front of the sides of the box formed by the frame and all around it is fixed a peripheral tube 8 which acts as a bumper and which also makes it possible to fix the suction shoe.

Le fond de la cuve 6 est doté d'un orifice de préférence axial et circulaire aligné avec l'orifice de la paroi du caisson et celui du carter du groupe aspirateur 4.The bottom of the tank 6 has a preferably axial and circular orifice aligned with the orifice in the wall of the box and that of the housing of the vacuum cleaner group 4.

De préférence le couvercle 7 coopère avec le bord supérieur de la cuve par emboîtement, tout autre disposition peut cependant être adaptée à la machine selon l'invention pour obtenir une obturation étanche de la cuve par le couvercle.Preferably the cover 7 cooperates with the upper edge of the tank by interlocking, any other arrangement can however be adapted to the machine according to the invention to obtain a sealed closure of the tank by the cover.

Le couvercle 7 est percé au voisinage de son bord d'un orifice de passage de l'embout ou manchon 9 avec ajutage 10 de déversement des poussières sur lequel se branche le conduit 11 d'aspiration.The cover 7 is pierced in the vicinity of its edge with an orifice for the passage of the endpiece or sleeve 9 with a nozzle 10 for discharging dust onto which the suction duct 11 is connected.

Le couvercle 7 a la forme d'une calotte sphérique.The cover 7 has the shape of a spherical cap.

L'embout 9 est un tube coudé à angle droit en sorte que l'ajutage soit dirigé vers le fond de la cuve tangentiellement à la paroi interne de ladite cuve.The end piece 9 is a tube bent at a right angle so that the nozzle is directed towards the bottom of the tank tangentially to the internal wall of said tank.

La partie de l'embout orienté vers le fond de la cuve est inclinée en biais par rapport à l'axe de la cuve et à l'une des génératrices de ladite cuve ou à l'un des côtés de ladite cuve suivant un angle de l'ordre de 15 à 75°.The part of the endpiece oriented towards the bottom of the tank is inclined at an angle with respect to the axis of the tank and to one of the generatrices of said tank or to one of the sides of said tank at an angle of around 15 to 75 °.

Cette disposition de l'invention permet comme il sera exposé plus avant de diriger le flux de fluide aspiré tangentiellement à la cuve suivant une spire théorique qui s'enroule sur la paroi interne de la cuve en sorte que le déversement des poussières s'effectue tangentiellement à la paroi de la cuve en lui donnant un mouvement tourbillonnaire.This arrangement of the invention allows, as will be explained above, to direct the flow of fluid aspirated tangentially to the tank according to a theoretical turn which is wound on the internal wall of the tank so that the dust is discharged tangentially. to the wall of the tank giving it a swirling motion.

A l'intérieur de l'enceinte est disposé un réceptacle à poussière 12 qui est constitué par un sac en un matériau textile imperméable à la poussière et perméable à l'air.Inside the enclosure is arranged a dust receptacle 12 which is constituted by a bag made of a textile material impermeable to dust and breathable.

Le sac est doté d'un dispositif connu de fixation sur le bord supérieur de l'enceinte qui peut être comme représenté constitué d'une rondelle 13 à laquelle est soudée la paroi du sac et qui repose sur le bord de l'enceinte.The bag is provided with a known device for fixing on the upper edge of the enclosure which can be as shown consisting of a washer 13 to which the wall of the bag is welded and which rests on the edge of the enclosure.

La paroi du sac est séparée de la paroi interne de l'enceinte par un espacement 14, le volume du sac étant de dimension inférieure au volume interne de l'enceinte.The wall of the bag is separated from the internal wall of the enclosure by a spacing 14, the volume of the bag being of dimension smaller than the internal volume of the enclosure.

Le volume délimité par la paroi du sac est fermé par un fond 15. De préférence la largeur ou diamètre du fond 15 est inférieure à la largeur ou diamètre de l'orifice du sac délimité par la rondelle 13 en sorte que le sac ait la forme d'un tronc de cône inversé dont la section inférieure délimitée par le fond est disposée en regard de l'orifice d'aspiration de la turbine et dont la paroi est inclinée par rapport à l'axe de l'enceinte et à sa paroi.The volume delimited by the wall of the bag is closed by a bottom 15. Preferably the width or diameter of the bottom 15 is less than the width or diameter of the orifice of the bag delimited by the washer 13 so that the bag has the shape of an inverted truncated cone, the lower section of which is delimited by the bottom and is disposed opposite the suction orifice of the turbine and the wall of which is inclined relative to the axis of the enclosure and to its wall.

Il va de soi que dans le cas d'une enceinte ou cuve non cylindrique le sac est adapté à la conformation du volume interne de l'enceinte en présentant la même caractéristique de largeur décroissante lui conférant une forme plus resserrée au niveau de son fond qu'à son orifice.It goes without saying that in the case of a non-cylindrical enclosure or tank, the bag is adapted to the conformation of the internal volume of the enclosure by having the same characteristic of decreasing width, giving it a tighter shape at its bottom than 'to its orifice.

Cette forme peut par exemple être tronc pyramidale. Cette disposition de l'invention permet d'éviter que la paroi du sac ne soit plaquée contre la paroi de l'enceinte lors de l'aspiration.This shape can for example be a pyramidal trunk. This arrangement of the invention makes it possible to prevent the wall of the bag from being pressed against the wall of the enclosure during suction.

Comme représentée en fig. 1, 2, 3 la cuve est de préférence amovible et fixée sur le bâti 1 au moyen d'attaches rapides.As shown in fig. 1, 2, 3 the tank is preferably removable and fixed to the frame 1 by means of quick couplers.

Le groupe aspirateur 8 est également fixé sous la paroi supérieure du bâti 1 au moyen d'un système par exemple d'attaches rapides ayant pour but de faciliter son enlèvement.The vacuum cleaner group 8 is also fixed under the upper wall of the frame 1 by means of a system, for example of quick couplers intended to facilitate its removal.

Suivant une forme préférée de réalisation (fig. 1, 2) sous le bâti 1 est fixée une patte coudée 17 sur laquelle repose le carter du groupe. Un système de vis 18 articulée avec molette de manoeuvre permet de bloquer le groupe en position.According to a preferred embodiment (fig. 1, 2) under the frame 1 is fixed a bent tab 17 on which the group housing rests. A system of articulated screws 18 with an operating wheel makes it possible to lock the group in position.

Le sabot suceur de la machine selon l'invention qui est fixé en bout du conduit 11 souple peut être soit mobile indépendamment de la machine telle que définie plus avant, soit fixé devant elle au caisson ou au tube 3 de manière connue.The suction shoe of the machine according to the invention which is fixed at the end of the flexible conduit 11 can be either movable independently of the machine as defined above, or fixed in front of it to the box or to the tube 3 in a known manner.

Le sabot suceur comprend un châssis recevant les différents organes de forme sensiblement rectangulaire réalisé par soudage de longerons tubulaires et de traverses.The suction shoe comprises a chassis receiving the various shaped organs substantially rectangular made by welding tubular beams and crosspieces.

Le châssis 11 est couvert par un capot de protection en forme de caisson fixé audit châssis de préférence par boulonnage de manière à être amovible.The chassis 11 is covered by a protective cover in the form of a box fixed to said chassis preferably by bolting so as to be removable.

De part et d'autre du capot sont articulés les branches parallèles d'une barre de manoeuvre permettant de pousser et de diriger le sabot suceur lorsqu'il n'est pas fixé à la machine aspirateur.On both sides of the cover are articulated the parallel branches of an operating bar making it possible to push and direct the suction shoe when it is not fixed to the vacuum cleaner machine.

Le sabot suceur de la machine selon l'invention peut être doté d'organes de roulement qui peuvent être réglables en hauteur.The suction shoe of the machine according to the invention can be provided with rolling members which can be adjustable in height.

Les organes de roulement peuvent être constitués de rouleaux, l'un des rouleaux peut être moteur, l'autre ou les autres étant librement rotatifs.The rolling members may consist of rollers, one of the rollers may be motor, the other or the others being freely rotatable.

Le châssis de l'appareil tel que décrit reçoit des organes à action mécanique sur le sol pour en détacher les salissures et impuretés et un ou des embouts d'aspiration reliés à la machine par le conduit 11 représenté schématiquement.The chassis of the device as described receives mechanically acting members on the ground to detach dirt and impurities and one or more suction nozzles connected to the machine by the conduit 11 shown diagrammatically.

Les organes de nettoyage du sol à action mécanique sur celui-ci comprenent une brosse 20 cylindrique, sensiblement médiane au châssis dont au moins une génératrice est en contact avec le sol, montée transversalement au châssis et au sens d'avancement de l'appareil. L'arbre de la brosse 20 est monté rotatif dans deux paliers fixés respectivement sur chacun des longerons du châssis.The mechanically acting soil cleaning members on this comprise a cylindrical brush, substantially median to the chassis, at least one generator of which is in contact with the ground, mounted transversely to the chassis and in the direction of travel of the apparatus. The shaft of the brush 20 is rotatably mounted in two bearings fixed respectively on each of the frame rails.

L'entraînement de la brosse s'effectue par courroie comme il sera décrit plus avant.The brush is driven by a belt as will be described later.

Transversalement au châssis entre la brosse cylindrique 20 et la paroi avant de son capot est montée une platine horizontale 21 surélevée par rapport aux montants parallèles 22 du châssis au moyen d'équerres ou de goussets soudés suivant un axe transversal au châssis sur respectivement chacun des longerons.Transversal to the chassis between the cylindrical brush 20 and the front wall of its cover is mounted a horizontal plate 21 raised relative to the parallel uprights 22 of the chassis by means of brackets or gussets welded along an axis transverse to the chassis on each of the side members respectively .

Sous la platine 21 est montée suivant un alignement de préférence parallèle à l'axe de la brosse 20 une série de brosses à axe vertical actionnées en rotation en plan horizontal, chacune d'elles étant entraînée sur une trajectoire fermée.Under the plate 21 is mounted in an alignment preferably parallel to the axis of the brush 20 a series of brushes with vertical axis actuated in rotation in the horizontal plane, each of them being driven on a closed path.

A cet effet, la platine est dotée de perçages alignés sur un même axe.For this purpose, the plate is provided with holes aligned on the same axis.

Dans chacun des perçages est calé un tourillon 23 par un épaulement 24 et un écrou 25.In each of the bores is wedged a pin 23 by a shoulder 24 and a nut 25.

Sous la platine est calé sur le tourillon un engrenage fixe 26 au moyen d'un pion 27 pénétrant dans un perçage de la platine et dudit engrenage.Under the plate is fixed on the journal a fixed gear 26 by means of a pin 27 penetrating into a hole in the plate and said gear.

Entre l'épaulement de butée du tourillon et l'engrenage fixe 26 est monté une roue dentée rotative 28.Between the abutment shoulder of the journal and the fixed gear 26 is mounted a rotary toothed wheel 28.

La roue dentée 28 est dotée d'un perçage par lequel passe l'axe rotatif 29 de la brosse 30 calé en enfoncement dans le perçage par un épaulement de butée, une bague en une matière autolubrifiante facilite la rotation de l'axe 29.The toothed wheel 28 is provided with a bore through which the rotary axis 29 of the brush 30 passes, wedged into the bore by a stop shoulder, a ring made of a self-lubricating material facilitates the rotation of the axis 29.

Sur l'extrémité de l'axe 29 est calé un pignon tangent à l'engrenage fixe avec lequel il s'engrenne.On the end of the axis 29 is wedged a pinion tangent to the fixed gear with which it meshes.

Une des roues dentées est actionnée autour du tourillon 23 en rotation par un pignon moteur tangent 32 actionné au moyen d'un renvoi d'angle représenté schématiquement en 33 en prise sur l'arbre de sortie du moteur électrique 34 fixé sur la platine.One of the toothed wheels is actuated around the journal 23 in rotation by a tangent motor pinion 32 actuated by means of a bevel gear shown diagrammatically at 33 engaged on the output shaft of the electric motor 34 fixed on the plate.

Un arbre de sortie 35 du renvoi d'angle 33 dans le prolongement de l'arbre de sortie du moteur reçoit une poulie à gorge qui par une courroie entraîne en rotation une poulie à gorge calée sur l'arbre de la brosse 20.An output shaft 35 of the bevel gear 33 in the extension of the output shaft of the motor receives a grooved pulley which, by a belt, rotates a grooved pulley wedged on the shaft of the brush 20.

La roue dentée 28 entraîne la brosse 30 suivant une trajectoire en circuit fermé circulaire et par engrenement du pignon 31 et de l'engrenage fixe la brosse est animée au cours de cette trajectoire d'un mouvement de rotation continu.The toothed wheel 28 drives the brush 30 along a circular closed circuit trajectory and by gear of the pinion 31 and of the fixed gear the brush is animated during this trajectory of a continuous rotational movement.

La trajectoire circulaire avec rotation de chacune des brosses 30 en plan parallèle contribue en accroissant la surface du sol en contact avec chacune des brosses à détacher les salissures du sol et à rendre la machine selon l'invention plus efficace.The circular trajectory with rotation of each of the brushes 30 in parallel plane contributes by increasing the surface of the ground in contact with each of the brushes to detach the dirt from the ground and to make the machine according to the invention more efficient.

Des pignons intermédiaires 38 tangents à deux roues dentées 26 consécutives et s'engrenant avec elles permettent de transmettre la rotation de la première roue dentée actionnée par le pignon moteur aux autres en sorte que les brosses soient toutes entraînées suivant une trajectoire circulaire qui leur est propre.Intermediate pinions 38 tangent to two toothed wheels 26 consecutive and meshing with them make it possible to transmit the rotation of the first toothed wheel actuated by the driving pinion to the others so that the brushes are all driven along a circular trajectory which is proper to them .

Pour éviter la collision des brosses entre elles le calage de chacune des brosses est identique sur chacune des roues dentées.To avoid the brushes colliding with each other, the timing of each of the brushes is identical on each of the toothed wheels.

La rotation des brosses en plan horizontal suivant une trajectoire fermée permet d'accroître la surface balayée par chacue brosse quelles que soient les différences de niveau du sol à nettoyer.Rotating the brushes in a horizontal plane along a closed path makes it possible to increase the surface swept by each brush whatever the differences in level of the soil to be cleaned.

Afin d'accroître cette capacité à nettoyer des sols présentant des différences de niveau les fibres de chacune des brosses sont de longueur croissante de leur centre vers leur périphérie.In order to increase this capacity for cleaning floors with differences in level, the fibers of each of the brushes are of increasing length from their center to their periphery.

Le sabot suceur est doté d'un ou plusieurs embouts d'aspiration situés avant et/ou après les brosses à action mécanique sur le sol.The suction shoe has one or more suction nozzles located before and / or after the brushes with mechanical action on the floor.

Il va de soi que le sabot est doté du câblage électrique d'alimentation et de commande de ses différents organes.It goes without saying that the shoe has electrical supply and control wiring for its various components.

La commande peut être effectuée soit à partir de la barre de manoeuvre dotée de dispositifs de commande des brosses, soit à partir du tableau de commande de l'aspirateur tel qu'énoncé plus haut doté d'un câblage de raccordement à celui du sabot.The control can be carried out either from the operating bar provided with brush control devices, or from the control panel of the vacuum cleaner as stated above provided with a wiring connection to that of the shoe.

De préférence le sabot selon l'invention est fixé à l'avant de l'aspirateur par tout moyen connu en sorte qu'en poussant l'un, l'utilisateur pousse l'autre.Preferably the shoe according to the invention is fixed to the front of the vacuum cleaner by any known means so that by pushing one, the user pushes the other.

En fig. 6 est représenté un autre mode de réalisation du sabot suceur destiné à être raccordé à l'aspirateur tel que défini.In fig. 6 shows another embodiment of the suction shoe intended to be connected to the vacuum cleaner as defined.

Selon ce mode de réalisation le châssis constitué par assemblage de longerons et traverses couvert par un capot est doté d'un organe de roulement 18 librement rotatif transversalement au châssis.According to this embodiment, the chassis constituted by the assembly of beams and crosspieces covered by a cover is provided with a rolling member 18 freely rotatable transversely to the chassis.

Transversalement au châssis et dans la partie avant de celui-ci est montée une brosse rotative 20 dont au moins une génératrice est en contact avec le sol.Crosswise to the chassis and in the part before this is mounted a rotary brush 20 of which at least one generator is in contact with the ground.

La brosse fait rotation dans des paliers fixés au châssis. Son axe est doté d'une poulie à gorge entraînée en rotation par une courroie coopérant avec l'arbre de sortie d'un moteur électrique de type connu fixé au châssis.The brush rotates in bearings fixed to the frame. Its axis is provided with a grooved pulley rotated by a belt cooperating with the output shaft of an electric motor of known type fixed to the chassis.

Le sabot suceur est doté de deux embouts suceurs 39 et 40 transversaux au châssis réunis au conduit d'aspiration 11 en formant une dérivation 41.The suction shoe has two suction tips 39 and 40 transverse to the frame joined to the suction duct 11 by forming a bypass 41.

L'embout suceur 39 vient en avant de la brosse cylindrique, l'embout suceur 40 est placé à l'arrière de la brosse cylindrique.The suction nozzle 39 comes in front of the cylindrical brush, the suction nozzle 40 is placed at the rear of the cylindrical brush.

Les lèvres de chacun des embouts sont au-dessus du niveau du sol à nettoyer.The lips of each of the nozzles are above the level of the floor to be cleaned.

De préférence un clapet articulé 42 est actionné par une électro-vanne 43 reliée au clapet par une tige rigide.Preferably an articulated valve 42 is actuated by a solenoid valve 43 connected to the valve by a rigid rod.

Un axe transversal à la dérivation et dont les extrémités sont fixées de part et d'autres du sabot par exemple dans des perçages des flancs du capot permet de faire basculer l'ensemble 39, 40 en sorte que l'un ou l'autre des embouts suceurs soit en contact avec le sol.An axis transverse to the bypass and the ends of which are fixed on either side of the shoe, for example in holes in the sides of the cover, makes it possible to tilt the assembly 39, 40 so that one or the other of the nozzles are in contact with the ground.

Le basculement peut être obtenu par tout moyen. De préférence on utilise un électroaimant 44 fixé au châssis et relié à l'un des embouts suceurs par une tige rigide.Failover can be achieved by any means. Preferably, an electromagnet 44 is used fixed to the chassis and connected to one of the nozzle ends by a rigid rod.

Suivant une autre forme de réalisation de l'invention non représentée chacun des embouts est doté d'un manchon souple en accordéon ce qui permet au moyen d'un système à vis, crémaillère ou à chaînette de relever l'un ou l'autre des embouts.According to another embodiment of the invention not shown, each of the end pieces is provided with a flexible accordion sleeve which allows by means of a screw, rack or chain system to raise one or the other of the end caps.

Dans la forme de réalisation de la machine selon l'invention telle que représentée, lorsque la turbine est mise en marche, elle extrait l'air contenu dans l'enceinte en y produisant une dépression et une aspiration des poussières à travers le conduit fixé au couvercle.In the embodiment of the machine according to the invention as shown, when the turbine is started, it extracts the air contained in the enclosure by producing a vacuum and a dust suction through the duct fixed to the lid.

Sous l'effet de l'extraction qui, en raison de l'espacement 14, s'effectue tout autour du sac et à travers sa paroi, ledit sac se gonfle et se tend, son fond se cintre en une calotte bombée vers l'orifice du carter de la turbine, sans que toutefois les parois dudit sac se plaquent contre celle de l'enceinte.Under the effect of the extraction which, due to the spacing 14, takes place all around the bag and through its wall, said bag inflates and tightens, its bottom bends into a domed cap towards the orifice of the turbine casing, without however the walls of said bag pressing against that of the enclosure.

De ce fait, l'air est extrait de l'enceinte à travers la totalité de la paroi du sac ce qui permet d'utiliser au maximum la capacité d'extraction de la turbine.Therefore, the air is extracted from the enclosure through the entire wall of the bag which allows maximum use of the extraction capacity of the turbine.

En raison de la conformation de l'embout dont l'ajutage permet le passage dans l'enceinte de l'air chargé de poussières aspirées au niveau du sabot suceur, le flux d'air est dirigé tangentiellement à la paroi cylindrique de l'enceinte et suivant une spire.Due to the shape of the nozzle, the nozzle of which allows the passage of air charged with dust sucked in at the suction shoe, the air flow is directed tangentially to the cylindrical wall of the enclosure. and following a turn.

Ledit flux d'air est intercepté par la paroi tronconique du sac et par le fond cintré en calotte en sorte qu'il est renvoyé vers le couvercle qui par sa conformation en calotte sphérique joue un rôle de déflecteur dudit flux d'air qui effectue à l'intérieur du sac un mouvement tourbillonnaire elliptique.Said air flow is intercepted by the frustoconical wall of the bag and by the bottom curved in a cap so that it is returned towards the cover which by its conformation in a spherical cap plays a role of deflector of said air flow which inside the bag an elliptical swirling motion.

Au cours de ce mouvement du flux d'air qui contribue à détacher les particules de poussières de la paroi du sac et surtout à empêcher qu'elles s'y fixent, les poussières les plus lourdes tombent par gravité et viennent se concentrer sur le fond du sac ledit flux d'air fonctionnant à la manière d'un cyclone.During this movement of the air flow which contributes to detaching the dust particles from the wall of the bag and especially to prevent them from fixing there, the heaviest dusts fall by gravity and come to concentrate on the bottom from the bag, said air flow operating in the manner of a cyclone.

Cette disposition de l'invention permet d'éviter le colmatage des pores du sac qui freinerait l'aspiration.This arrangement of the invention avoids clogging of the pores of the bag which would slow down the suction.
