Abstract

PCT No. PCT/FR91/00157 Sec. 371 Date Oct. 25, 1991 Sec. 102(e) Date Oct. 25, 1991 PCT Filed Feb. 26, 1991 PCT Pub. No. WO91/12762 PCT Pub. Date Sep. 5, 1991.A vacuum cleaning device comprising an enclosure (20) containing a chamber (30) in which is located at least one flexible wall such as a bag (2) designed to stop solid particles while letting through the air, and containing a compartment (40) provided with a movable tray (41) located beneath the chamber (30) in order to catch the solid particles which fall by the force of gravity. The device is characterized in that it includes a means (5) for forming a sealed connection between the flexible wall (2) and the tray (41), the latter comprising at least one inlet (48-49) for air to be filtered. In a preferred embodiment, the flexible wall (2) is secured by frame (3) the edge of which acrries a flexible seal (5) so that the assembly (1) thereby formed is self-contained and interchangeable without needing to be dismantled.

Description

On connaît de multiples dispositifs de nettoyage destinés à évacuer des particules solides : poussières, déchets, etc. par aspiration.There are known multiple cleaning devices intended for removing solid particles: dust, waste, etc. by suction.

Ils comprennent tous un moteur et une turbine provoquant une dépression dans un conduit dont une extrémité doit être placée devant la zone à nettoyer et l'autre est située à l'entrée d'une chambre contenant au moins une paroi souple telle qu'un sac à travers lequel la turbine aspire l'air et qui joue le rôle d'un filtre car il retient les particules solides tandis qu'il laisse passer l'air aspiré par la turbine.They all include a motor and a turbine causing a vacuum in a duct, one end of which must be placed in front of the area to be cleaned and the other is located at the entrance to a chamber containing at least one flexible wall such as a bag through which the turbine sucks in air and which acts as a filter because it retains solid particles while it lets the air sucked in by the turbine pass.

La paroi souple est généralement disposée verticalement sur une armature en présentant une ouverture à sa partie inférieure, située au dessus d'un bac de récupération dans lequel tombent par gravité, les particules solides non accrochées à la paroi souple Lors du nettoyage ou du remplacement de la paroi souple, on lui imprime des secousses afin de faire tomber dans le bac de récupération le maximum de particules et de poussiéres.The flexible wall is generally arranged vertically on a frame by presenting an opening at its lower part, located above a collecting tank into which fall by gravity, the solid particles not attached to the flexible wall When cleaning or replacing the flexible wall, it is shaken to make the most of the particles and dust fall into the recovery tank.

Le bac est monté mobile dans un compartiment d'où on le retire pour évacuer son contenu.The bin is mounted mobile in a compartment from which it is removed to evacuate its contents.

L'air chargé de poussières est introduit dans le compartiment et, pour éviter de trop grandes pertes de charge, on ferme ce compartiment au moyen d'une porte qui est plaquée contre un dormant avec interposition d'un joint d'étanchéité.Dust-laden air is introduced into the compartment and, to avoid too great a pressure drop, this compartment is closed by means of a door which is pressed against a frame with the interposition of a seal.

Une telle structure ne donne pas satisfaction et cela à plusieurs titres:

  • Pour de simples raisons géométriques, le bac de récupération ne peut pas occuper exactement tout le volume intérieur du compartiment car il faut prévoir un jeu permettant les mouvements du bac qui est mobile par rapport au compartiment fixe. Il en résulte que des particules solides tombent à l'extérieur du bac, dans le compartiment, et non à l'intérieur. Ces particules s'accumulent et finissent par créer des amas qui, en grossisssant, finissent par géner les mouvements du bac.
  • Le bac est ainsi repoussé petit à petit et arrive un moment ou l'on ne peut fermer la porte du compartiment qu'en forçant sur le bac puis, ces circonstances s'aggravant nécessairement, il devient impossible de fermer la porte. Il faut alors retirer le bac et nettoyer le compartiment à la main, ce qui est une opération difficile.
  • Les ouvertures et fermetures successives de la porte provoquent tout naturellement l'usure du joint dont l'efficacité se dégrade jusqu'au moment où il faut le remplacer. Mais, par souci d'économie, on attend le plus longtemps possible avant de changer le joint de sorte que, petit à petit et pourrait-on dire de manière insensible, l'étanchéité diminue de telle sorte que la turbine aspire de l'air extérieur par les intervalles non obturés de la porte au lieu d'aspirer l'air chargé de poussières exclusivement par le conduit. Dans la pratique, cela peut provoquer jusqu'à 80 % de perte de rendement de l'appareil.
  • La paroi souple, ou sac, est fixé à un cadre au moyen de boulons qui sont une gêne pour le retrait facile du sac en vue de son nettoyage ou de son remplacement. En outre, le sac doit être retiré et remis en place par le côté amont du système, c'est-à-dire du côté sale, empoussiéré par l'air chargé, ce qui est une opération pénible.
Such a structure is not satisfactory and this for several reasons:
  • For simple geometric reasons, the recovery tank cannot occupy exactly the entire interior volume of the compartment because it is necessary to provide a clearance allowing the movements of the container which is movable relative to the fixed compartment. As a result, solid particles fall outside the tank, in the compartment, and not inside. These particles accumulate and eventually create clusters which, when growing, end up hampering the movements of the tank.
  • The bin is thus pushed back little by little and arrives at a time when the compartment door can only be closed by forcing on the bin, then, these circumstances necessarily getting worse, it becomes impossible to close the door. It is then necessary to remove the container and clean the compartment by hand, which is a difficult operation.
  • The successive openings and closings of the door naturally cause the wear of the seal, the effectiveness of which deteriorates until it is time to replace it. But, for the sake of economy, we await the as long as possible before changing the seal so that, little by little and one could say insensitively, the tightness decreases so that the turbine sucks in outside air through the unobstructed intervals of the door instead suck the dust-laden air exclusively through the duct. In practice, this can cause up to 80% loss of device performance.
  • The flexible wall, or bag, is fixed to a frame by means of bolts which are a hindrance for easy removal of the bag for cleaning or replacement. In addition, the bag must be removed and replaced by the upstream side of the system, that is to say on the dirty side, dusted by the charged air, which is a tedious operation.

Pour fixer l'état de la technique on peut citer :
   Le brevet GB-A-865 262 qui décrit un aspirateur comportant un bac contenant un sac à poussières et un couvercle qui surmonte l'ensemble bac/sac à l'intérieur duquel est disposé une paroi filtrante.To fix the state of the art we can cite:
GB-A-865 262 which describes a vacuum cleaner comprising a container containing a dust bag and a cover which surmounts the container / bag assembly inside which a filtering wall is disposed.

Cette paroi filtrante est maintenue en forme par une armarture complexe pour être tendue.This filtering wall is held in shape by a complex frame to be stretched.

Entre le couvercle et le haut du bac est disposé un joint d'étanchéité qui peut être supporté par le couvercle ou par le bac.Between the cover and the top of the tank is arranged a seal which can be supported by the cover or by the tank.

Des crochets pivotants sur des piéces articulées assujetties au bac coopérent avec des trous ménagés dans le couvercle afin d'assurer la fermeture de l'aspirateur et de maintenir le bac contre le joint d'étanchéité.Swivel hooks on articulated parts secured to the tank cooperate with holes made in the cover in order to close the vacuum cleaner and to keep the tank against the seal.

En raison de la présence d'un sac à poussières disposé dans le bac, une partie non négligeable des poussières tombe à l'extérieur du sac puisqu'il n'y a pas d'étanchéité entre le sac et le bac. Il en résulte un encrassement du bac qui nécessite son nettoyage simultanément à celui du sac. De plus, le filtre est assujetti à une armature métallique complexe qui génère son usure par frottement.Due to the presence of a dust bag placed in the bin, a significant part of the dust falls outside the bag since there is no seal between the bag and the bin. This results in fouling of the tank which requires cleaning simultaneously with that of the bag. In addition, the filter is subject to a complex metal frame which generates its wear by friction.

Le brevet US-A-2.044.827 qui décrit un aspirateur comportant un logement supérieur à l'intérieur duquel est assujettie sur une armature complexe une paroi filtrante totalement indépendante d'un bac à poussières inférieur. Il en résulte une usure importante de la paroi filtrante par frottement.The patent US-A-2,044,827 which describes a vacuum cleaner comprising an upper housing inside which is fixed on a complex frame a filter wall completely independent of a lower dust bin. This results in significant wear of the filter wall by friction.

Par ailleurs, cet aspirateur ne comporte aucun moyen pour assurer une bonne étanchéité entre ce filtre, le bac à poussières et le compartiment contenant ce bac ce qui provoque des pertes de charges importantes qui diminuent considérablement le rendement.Furthermore, this vacuum cleaner does not have any means to ensure a good seal between this filter, the dust bin and the compartment containing this bin, which causes significant pressure drops which considerably reduce the yield.

Le brevet CH-A-409.266 qui décrit un aspirateur industriel comportant dans sa partie inférieure un bac à poussières équivalent à une poubelle. Ce bac à poussières est monté mobile de bas en haut par une plaque associée à un étrier. La partie supérieure de l'aspirateur comprend un filtre maintenu sur une armature complexe, tout à fait indépendant du bac.Patent CH-A-409,266 which describes an industrial vacuum cleaner comprising in its lower part a dust bin equivalent to a dustbin. This dust bin is mounted movable from bottom to top by a plate associated with a bracket. The upper part of the vacuum cleaner includes a filter held on a complex frame, completely independent of the tank.

Ce receptacle est monté mobile de bas en haut par des moyens mécaniques complexes qui n'assurent pas une étanchéité correcte et directe entre le filtre et le receptacle. Par ailleurs, le filtre est assujetti à des armatures métalliques de sorte qu'il subit des contraintes importantes et qu'il s'use.This receptacle is mounted movable from bottom to top by complex mechanical means which do not ensure correct and direct sealing between the filter and the receptacle. In addition, the filter is subjected to metallic reinforcements so that it undergoes significant stresses and that it wears out.

Cet appareil comporte un joint d'étanchéité entre une partie intermédiaire fixe et une partie inférieure amovible, joint qui subit les contraintes mécaniques résultant des mises en place et des retraits successifs du réceptacle. Il en résulte une diminution de l'étanchéité et donc de performances de l'appareil par perte de charge.This device comprises a seal between a fixed intermediate part and a removable lower part, a seal which undergoes the mechanical stresses resulting from the positioning and removal of the receptacle. This results in a reduction in the seal and therefore in the performance of the device by pressure drop.

Le brevet DE-A-3.723.148 décrit un appareil de nettoyage par aspiration dont la partie supérieure comporte des moyens de filtration et la partie inférieure un bac contenant un sac à poussières amovible et monté mobile de bas en haut.Patent DE-A-3,723,148 describes a suction cleaning apparatus, the upper part of which comprises filtration means and the lower part a bin containing a removable dust bag and mounted movable from bottom to top.

Ce bac est assujetti par un ensemble mécanique complexe de pièces articulées à la partie supérieure lorsque l'appareil est en position de fonctionnement.This tank is secured by a complex mechanical assembly of parts articulated at the top when the device is in the operating position.

Le brevet US-A-4.222.753 qui décrit un appareil de nettoyage comportant un bac sans entrée d'air surmonté d'une partie qui comporte un filtre. Ce filtre est maintenu à sa base par une pièce métallique associée à un ressort qui exerce une force radiale, ce qui accentue les efforts mécaniques supportés par le filtre et donc son usure voire sa déchirure.US-A-4,222,753 which describes a cleaning device comprising a tank without air inlet surmounted by a part which includes a filter. This filter is held at its base by a metal part associated with a spring which exerts a radial force, which accentuates the mechanical forces supported by the filter and therefore its wear or even its tear.

En outre, la partie inférieure est constituée par un bac contenant un sac qui n'interdit pas la chute accidentelle de poussières entre lui et le bac et il n'y a aucune liaison mécanique étanche avec le filtre.In addition, the lower part consists of a container containing a bag which does not prevent the accidental fall of dust between it and the container and there is no tight mechanical connection with the filter.

De plus, cet appareil ne comporte aucun moyen assurant l'étanchéité entre le bac et la partie qui le surmonte et, donc, l'appareil ne peut fournir des performances de rendement satisfaisantes.In addition, this device has no means ensuring the seal between the tank and the part which overcomes it and, therefore, the device can not provide satisfactory performance performance.

Les brevets US-A-3.910.781 et FR-A-787.871 décrivent un aspirateur à poussières comportant un filtre assujetti et maintenu par une structure métallique complexe associée à des ressorts. Il en résulte une usure accrue de celui-ci.The patents US-A-3,910,781 and FR-A-787,871 describe a dust vacuum cleaner comprising a filter attached and held by a complex metallic structure associated with springs. This results in increased wear thereof.

La présente invention remédie à tous ces inconvénients en prévoyant une structure nouvelle à l'entrée de l'appareil qui permet de garentir un rendement maximum à l'appareil en supprimant les causes de fuites et de perte de charge.The present invention overcomes all these drawbacks by providing a new structure for the input of the device which guarantees maximum efficiency for the device by eliminating the causes of leaks and pressure drop.

En outre, cet appareil permet :

  • d'assurer une étanchéité directe et totale entre le filtre et le bac.
  • de supprimer les portes d'accés au compartiment contenant le bac.
  • d'assurer une propreté absolue du compartiment à l'intérieur duquel se trouve le bac à poussières.
In addition, this device allows:
  • ensure a direct and total seal between the filter and the tank.
  • remove the access doors to the compartment containing the bin.
  • ensure absolute cleanliness of the compartment inside which the dust bin is located.

A cette fin, l'invention a pour objet un dispositif de nettoyage par aspiration, du type comportant une enceinte comprenant d' une part une chambre dans laquelle se trouve au moins une paroi souple telle qu'un sac devant arrêter des particules solides tout en laissant passer l'air aspiré et, d'autre part, un compartiment devant contenir un bac amovible situé sous la chambre et destiné à recueillir les particules solides pouvant tomber par gravité, caractérisé en ce qu'il comprend des moyens de liaison étanches tels qu'un joint périphérique souple assujetti à la paroi souple et qui assure une liaison directe et étanche entre ladite paroi et le bac, lequel comporte au moins une entrée d'air.To this end, the subject of the invention is a suction cleaning device, of the type comprising an enclosure comprising on the one hand a chamber in which there is at least one flexible wall such as a bag which has to stop solid particles while allowing the sucked air to pass and, on the other hand, a compartment to contain a removable tray located under the chamber and intended to collect the solid particles which can fall by gravity, characterized in that it comprises watertight connecting means such as 'A flexible peripheral seal attached to the flexible wall and which provides a direct and sealed connection between said wall and the tank, which comprises at least one air inlet.

L'invention sera mieux comprise par la description détaillée ci-après, faite en référence au dessin annexé. Bien entendu, la description et le dessin ne sont donnés qu'à titre d'exemple indicatif et non limitatif.The invention will be better understood from the detailed description below, given with reference to the accompanying drawing. Of course, the description and the drawing are given only by way of an indicative and nonlimiting example.

La figure 1 est une vue schématique en perspective d'un ensemble conforme à l'invention, comprenant une paroi souple à trois chambres et une monture de fixation.Figure 1 is a schematic perspective view of an assembly according to the invention, comprising a flexible wall with three chambers and a mounting fixture.

La figure 2 est une vue schématique en perspective avec coupe partielle d'un dispositif complet conforme à l'invention, seuls les organes mécaniques eux-mêmes n'étant pas représentés (moteur, turbine, etc.).Figure 2 is a schematic perspective view with partial section of a complete device according to the invention, only the mechanical members themselves not being shown (engine, turbine, etc.).

Les figures 3 et 4 sont deux vues schématiques en perspective d'un dispositif complet conforme à l'invention, dont on a retiré un capot de protection devant masquer et protéger les organes mécaniques (moteur, turbine, etc.).Figures 3 and 4 are two schematic perspective views of a complete device according to the invention, which has been removed a protective cover to hide and protect the mechanical components (engine, turbine, etc.).

La figure 5 est une vue schématique partielle montrant le bac en cours de mise en place.Figure 5 is a partial schematic view showing the tray being put in place.

La figure 6 est une vue schématique partielle montrant le bac en position de fonctionnement.Figure 6 is a partial schematic view showing the tank in the operating position.

En se reportant au dessin, on voit qu'un dispositif conforme à l'invention comprend un ensemble 1 formé d'un sac 2 en tissu filtrant, qui présente une bordure 3 telle qu'un cadre rigide 4 sur les faces duquel est assujetti un joint d'étanchéité souple 5.Referring to the drawing, it can be seen that a device according to the invention comprises an assembly 1 formed of a bag 2 of filter cloth, which has an edge 3 such as a rigid frame 4 on the faces of which is subjected a flexible seal 5.

Le sac 2 et la bordure 3 peuvent être dissociables, notamment si l'on veut pouvoir nettoyer le sac 2 sans la bordure 3 puis les associer à nouveau. Dans ce cas, on utilise des organes d'assujettissement de tout type connu : bride et boulons, collier de serrage etc., ce problème pouvant être résolu aisément par l'homme de métier.The bag 2 and the border 3 can be dissociable, in particular if one wants to be able to clean the bag 2 without the border 3 and then associate them again. In this case, securing devices of any known type are used: flange and bolts, clamp, etc., this problem being able to be easily resolved by a person skilled in the art.

Le sac 2 et la bordure 3 peuvent aussi former un tout indissociable, par exemple en surmoulant directement le joint 5 sur l'embouchure du sac 2. Le joint 5 est réalisé en matière synthétique dont la rigidité est choisie pour permettre à la fois de donner une forme stable à l'embouchure du sac et d'assurer une déformation souple pour constituer un joint d'étanchéité.The bag 2 and the border 3 can also form an inseparable whole, for example by directly overmolding the seal 5 on the mouth of the bag 2. The seal 5 is made of synthetic material whose rigidity is chosen to allow both to give a stable shape at the mouth of the bag and provide flexible deformation to form a seal.

Dans ce cas, on stocke des ensembles 1 et on les remplace un par un au fur et à mesure des besoins, les ensembles 1 saturés ou usés étant éliminés purement et simplement.In this case, sets 1 are stored and replaced one by one as needed, the sets 1 saturated or worn being eliminated altogether.

Le sac 2 comprend, ainsi que cela est connu en soi, trois poches 6, 7 et 8 qui vont en se rétrécissant depuis une embouchure quadragulaire commune 9 jusqu'à un sommet individuel 10, 11 et 12.The bag 2 comprises, as is known per se, three pockets 6, 7 and 8 which tapering from a common quadragular mouth 9 to an individual vertex 10, 11 and 12.

Aux sommets 10, 11 et 12, se trouvent des boucles 13 destinées à l'accrochage de l'ensemble 1 dans un dispositif d'aspiration que l'on va décrire maintenant.At the peaks 10, 11 and 12, there are loops 13 intended for the attachment of the assembly 1 in a suction device which will now be described.

Sur les figures 2, 3 et 4, on voit qu'un dispositif conforme à l'invention comprend une enceinte 20 montée sur des roulettes 21 et fermée à sa partie supérieure par une plaque 22 supportant les différents organes mécaniques voulus, dont un moteur électrique 23 alimenté en courant par un câble 24 et une turbine 25 entraînée par le moteur 23 au moyen d'une courroie 26.In FIGS. 2, 3 and 4, it can be seen that a device according to the invention comprises an enclosure 20 mounted on casters 21 and closed at its upper part by a plate 22 supporting the various desired mechanical organs, including an electric motor 23 supplied with current by a cable 24 and a turbine 25 driven by the motor 23 by means of a belt 26.

La turbine est associée à un conduit 27 placé en regard d'un passage ménagé dans la plaque 22 et débouchant dans une chambre 30 munie de crochets 31 pour y suspendre l'ensemble 1 par ses boucles 13.The turbine is associated with a duct 27 placed opposite a passage formed in the plate 22 and opening into a chamber 30 provided with hooks 31 to suspend the assembly 1 by its loops 13.

La chambre 30 présente en façade une fenêtre 32 qui, en service normal, est obturée par une plaque amovible étanche (non représentée).The chamber 30 has a window 32 on the front which, in normal service, is closed by a removable waterproof plate (not shown).

Des cornières 33 sont fixées à l'intérieur des parois de la chambre 30 pour constituer une butée périphérique à la bordure 3.Angles 33 are fixed inside the walls of the chamber 30 to constitute a peripheral stop at the edge 3.

L'ensemble 1, mis en place, détermine un compartiment inférieur 40 dans lequel un bac 41 est monté mobile à la manière d'un tiroir, ce pourquoi il présente une poignée de manoeuvre 42.The assembly 1, put in place, determines a lower compartment 40 in which a tray 41 is mounted movable in the manner of a drawer, which is why it has an operating handle 42.

Le bac 41 présente un rebord plan continu 43 dont la largeur correspond sensiblement à celle du joint 5 de la bordure 3.The container 41 has a continuous flat edge 43 whose width corresponds substantially to that of the seal 5 of the edge 3.

Sur ses deux parois latérales opposées, le bac 41 possède deux rampes 44 et 45 situées à deux niveaux différents chacun un peu plus bas que des butées 46 et 47 placées à l'intérieur du compartiment 40. Chaque butée 46 et 47 est constituée par un galet monté pivotant afin d'éviter des frottements lors de leur mise en action comme on le décrira plus loin.On its two opposite side walls, the tank 41 has two ramps 44 and 45 located at two different levels each a little lower than stops 46 and 47 placed inside the compartment 40. Each stop 46 and 47 is constituted by a roller mounted pivoting in order to avoid friction when they are put into action as will be described later.

Des orifices 48 et 49 traversent les parois latérales du bac 41, orifices qui sont situés en regard de passages 28 et 29 ménagés à travers les parois de l'enceinte 20.Ports 48 and 49 pass through the side walls of tank 41, ports which are located opposite passages 28 and 29 formed through the walls of enclosure 20.

Le compartiment 40 n'a pas de fond afin d'éviter toute accumulation accidentelle de poussières lors des manipulations des ensembles 1 saturés, après retrait du bac 41. Mais pour faciliter les mouvements de ce dernier, on prévoit des glissières longitudinales 50 (figures 3 et 4) dont une centrale sur laquelle repose un galet 51 monté pivotant à l'avant du bac 41.The compartment 40 has no bottom in order to avoid any accidental accumulation of dust when handling the saturated assemblies 1, after removal of the container 41. However, to facilitate the movements of the latter, longitudinal slides 50 are provided (FIGS. 3 and 4) including a central unit on which a roller 51 pivotally mounted in front of the tank 41 rests.

En prévoyant que le compartiment 40 n'a pas de fond mais de simples cornières, les poussières qui tombent, après retrait du bac 41, lors du changement de sac, salissent le sol, ce qui peut n'avoir pas trop d'importance, par exemple lorsque le dispositif est situé dans un garage qui doit nécessairement être nettoyé de manière particulièrement énergique.By providing that the compartment 40 has no bottom but simple angles, the dust which falls, after removal of the container 41, when changing the bag, soil the soil, which may not be too important, for example when the device is located in a garage which must necessarily be cleaned in a particularly vigorous manner.

Dans d'autres cas, cette structure peut avoir des inconvénients et, afin d'éviter que les poussières ne salissent le sol, on prévoit un tiroir 60, engagé dans des guides fixes (non visibles sur le dessin) et qui est situé sous les glissières 50. Il reste en place quand on enlève l'ensemble 1 usagé et on le retire pour le vider avant de mettre en place le nouvel ensemble 1 propre.In other cases, this structure can have drawbacks and, in order to prevent dust from dirtying the ground, a drawer 60 is provided, engaged in fixed guides (not visible in the drawing) and which is located under the slides 50. It remains in place when the used assembly 1 is removed and remove it to empty it before installing the new clean set 1.

Le tiroir est, par exemple, muni de boutons 61 pour sa manoeuvre.The drawer is, for example, provided with buttons 61 for its operation.

Le fonctionnement du dispositif qui vient d'être décrit est le suivant :The operation of the device which has just been described is as follows:

On place un ensemble 1 dans la chambre 30 en l'introduisant de bas en haut, par le compartiment 40, après retrait du bac 41. Pour plus de commodité, on retire la plaque de fermeture (non représentée) qui obture normalement la fenêtre 32. On accroche les boucles 13 aux crochets 31 et l'on s'assure que la bordure 3 est bien en appui contre les cornières 33, puis on remet en place la plaque de fermeture sur la fenêtre 32.An assembly 1 is placed in the chamber 30 by introducing it from bottom to top, through the compartment 40, after removal of the container 41. For greater convenience, the closure plate (not shown) is removed which normally closes the window 32 The loops 13 are hooked to the hooks 31 and it is ensured that the edge 3 is well pressed against the angles 33, then the closure plate is replaced on the window 32.

On introduit le bac 41 dans le compartiment 40 en faisant rouler son galet 51 sur la glissière centrale 50.The tank 41 is introduced into the compartment 40 by rolling its roller 51 on the central slide 50.

Pour que le mouvement du bac 41 soit simple et libre, il faut qu'il subsiste un jeu entre le rebord 43 du bac 41 et la face inférieure du joint 5 de la bordure 3. Ce jeu est un espace de hauteur H visible sur la figure 4.For the movement of the container 41 to be simple and free, there must be a clearance between the rim 43 of the container 41 and the underside of the seal 5 of the edge 3. This clearance is a space of height H visible on the figure 4.

A la fin du mouvement d'introduction du bac 41 selon la flêche F1 (figure 5), les rampes 44 et 45 rencontrent les galets 46 et 47. La forme et la disposition des rampes 44 et 45 sont choisies de telle sorte qu'en continuant à pousser le bac 41, on les oblige à passer par dessus les galets 46 et 47 et, en conséquence, elles élèvent le bac 41 selon la flêche F2 d' une distance au moins égale à la hauteur H.At the end of the movement of introduction of the container 41 according to the arrow F1 (FIG. 5), the ramps 44 and 45 meet the rollers 46 and 47. The shape and the arrangement of the ramps 44 and 45 are chosen so that at continuing to push the tray 41, they are forced to pass over the rollers 46 and 47 and, consequently, they raise the tray 41 according to the arrow F2 by a distance at least equal to the height H.

Le rebord 43 du bac 41 est alors énergiquement appliqué contre la bordure 3, en comprimant un peu le joint 5, ce qui assure la jonction étanche entre le bac 41 et le sac 2.The rim 43 of the container 41 is then energetically applied against the edge 3, by slightly compressing the seal 5, which ensures the tight connection between the container 41 and the bag 2.

On voit qu'avec l'invention, on constitue une enceinte continue et étanche formée d'une partie supérieure (la paroi souple 2) et d'une partie inférieure (le bac 41) sans intermédiaire entre elles, sauf le joint d'étanchéité 5.We see that with the invention, a continuous and sealed enclosure is formed, formed by an upper part (the flexible wall 2) and a lower part (the tank 41) without any intermediary between them, except the seal 5.

On choisit de raccorder un conduit d'aspiration 70 soit à l'orifice 48, soit à l'orifice 49 après mise en place du bac 41, en utilisant le passage 28 ou le passage 29. On place une tape 71 fixée par des boulons 72 sur l'orifice 48 ou 49 que l'on n'a pas choisi, mais le passage non utilisé 28 ou 29 peut rester ouvert sans inconvénient puisqu'il se trouve à l'extérieur de bac 41. Le passage utilisé, d'ailleurs, n'a lui-même aucune liaison étanche avec le conduit 70 qui est raccordé directement à l' orifice du bac 41.We choose to connect a suction duct 70 either to the orifice 48, or to the orifice 49 after installation of the tank 41, using the passage 28 or the passage 29. A tape 71 is placed fixed by bolts 72 on the orifice 48 or 49 which one has not chosen, but the unused passage 28 or 29 can remain open without drawback since it is outside of tank 41. The passage used, moreover, itself has no tight connection with the conduit 70 which is directly connected to the orifice of the tank 41.

On réalise ainsi une jonction sans fuite depuis une buse d'aspiration 73 de tout type connu fixée à l'extrémité du conduit 70 jusqu'à l'intérieur du sac 2, par l'intérieur du bac 41.A leak-free junction is thus produced from a suction nozzle 73 of any known type fixed at the end of the duct 70 to the inside of the bag 2, through the inside of the tank 41.

On branche le câble d 'alimentation 24 et l'on met le moteur 23 en marche, soit par action directe sur un interrupteur, soit en utilisant un mécanisme déclanché par un jeton, une carte ou une pièce de monnaie.The power cable 24 is connected and the motor 23 is started, either by direct action on a switch, or by using a mechanism triggered by a token, a card or a coin.

Le dispositif est alors utilisable de la manière bien connue en soi. La turbine 25 aspire l'air et crée ainsi une dépression à l'embouchure de la buse 73. L'air chargé de poussières et d'impuretés chemine dans le conduit 70, arrive dans le bac 41 et s'élève dans les trois poches 6, 7 et 8 du sac 2 qui offrent ainsi une très grande surface pour le passage de l'air et la rétention des poussières et impuretés.The device can then be used in a manner well known per se. The turbine 25 sucks in the air and thus creates a vacuum at the mouth of the nozzle 73. The air loaded with dust and impurities travels through the duct 70, arrives in the tank 41 and rises in the three pockets 6, 7 and 8 of the bag 2 which thus provide a very large surface for the passage of air and the retention of dust and impurities.

En cours d'usage, on peut imprimer des secousses au sac 2, par la fenêtre 32, afin de le désaturer en faisant tomber des poussières et impuretés accrochées au sac 2 dans le bac 41. On voit qu'ici ces poussières et impuretés ne peuvent rien souiller car elles ne peuvent tomber que dans le bac 41, relié de manière étanche au sac 2 par la bordure 3.In use, jolts can be printed in bag 2, through window 32, in order to desaturate it by causing dust to fall and impurities attached to the bag 2 in the container 41. It can be seen that these dusts and impurities cannot soil anything here because they can only fall into the container 41, tightly connected to the bag 2 by the edge 3.

Quand le sac 2 est devenu inutilisable parce qu'il est saturé ou usé, on débranche le conduit 70, on retire le bac 41 que l'on vide et l'on retire le sac 2 par le compartiment 40 après avoir décroché les boucles 13.When the bag 2 has become unusable because it is saturated or worn, the conduit 70 is disconnected, the tank 41 is removed and emptied and the bag 2 is removed by the compartment 40 after having unhooked the loops 13 .

Aucun organe de fixation ne vient gêner ou ralentir cette opération puisque l'on retire simultanément le sac 2 et la bordure 3.No fixing member interferes with or slows down this operation since the bag 2 and the border 3 are simultaneously removed.

On peut, tout aussitôt, remettre un ensemble 1 comme dit ci-dessus, ce qui ne prend que très peu de temps. On remet le bac 41 en place et l'on rebranche le conduit 70, et le dispositif est immédiatement opérationnel.We can immediately put back a set 1 as mentioned above, which takes only a very short time. The tray 41 is replaced and the duct 70 is reconnected, and the device is immediately operational.

Si l'on choisit le mode de réalisation selon lequel le sac 2 est dissociable de la bordure 3, on peut les séparer, sans perdre aucun temps de fonctionnement du dispositif, par exemple pour nettoyer et/ou laver le sac 2 en vue de son remploi.If one chooses the embodiment according to which the bag 2 is separable from the border 3, they can be separated, without losing any time of operation of the device, for example for cleaning and / or washing the bag 2 in view of its re-use.

Si l'on choisit le mode de réalisation selon lequel le sac 2 et la bordure 3 sont indissociables, on jette l'ensemble 1. Ce mode de réalisation peut sembler plus onéreux, mais comme le joint 5 n'est utilisé qu'une seule fois, il peut être moins robuste que s'il devait être réutilisé souvent et on peut donc le réaliser dans un matériau plus économique. Il en est de même pour le sac 2 qui peut être relativement fragile et donc bon marché.If we choose the embodiment according to which the bag 2 and the border 3 are inseparable, we discard the assembly 1. This embodiment may seem more expensive, but since the seal 5 is used only one times, it can be less robust than if it had to be reused often and it can therefore be made of a more economical material. It is the same for bag 2 which can be relatively fragile and therefore inexpensive.

La bordure 3 peut ne pas comprendre de cadre rigide 4, celui-ci étant seulement une aide à la mise en place et au maintien du joint 5.The border 3 may not include a rigid frame 4, this being only an aid in the establishment and maintenance of the seal 5.

Le raccord 74 utilisé pour la jonction du conduit 70 au bac 41 peut être de tout type connu et sa réalisation est à la portée de l'homme de métier, de sorte qu'il est inutile d'en donner une description complète.The connector 74 used for joining the conduit 70 to the tank 41 can be of any known type and its production is within the reach of those skilled in the art, so that it is unnecessary to give a complete description.

On remarque en particulier sur la figure 4, que les organes mécaniques sont d'un accès particulièrement facile car lorsque l'on a retiré le capot de protection (non représenté) on peut sans aucune difficulté changer la courroie 26 ou le conduit 27, ou bien faire une réparation, voire retirer le moteur 23 ainsi que la turbine 25, sans faire appel à une main d'oeuvre extérieure et spécialement formée.It is noted in particular in FIG. 4, that the mechanical members are of particularly easy access because when the protective cover has been removed (not shown) it is possible without any difficulty to change the belt 26 or the conduit 27, or make a repair, or even remove the motor 23 as well as the turbine 25, without calling on an external and specially trained workforce.
