Description

La présente invention concerne un suceur d'aspirateur pour tapis et moquettes, sols durs secs et sols durs mouillés.The present invention relates to a vacuum cleaner for carpets and rugs, dry hard floors and wet hard floors.

Un tel suceur comprend, d'une part, un boîtier muni d'une tubulure d'aspiration et faisant corps avec une semelle qui délimite entre des patins au moins un canal communiquant par au moins un passage avec ladite tubulure et, d'autre part, une platine mobile équipée d'une brosse traversant une fente ménagée entre la semelle et le boîtier, platine qui est commandée par un dispositif d'actionnement la plaçant en position haute pour le nettoyage des tapis ou moquettes ou en position basse pour le nettoyage des sols durs.Such a nozzle comprises, on the one hand, a housing provided with a suction tube and forming a body with a sole which delimits between pads at least one channel communicating by at least one passage with said tube and, on the other hand , a movable plate fitted with a brush passing through a slot made between the soleplate and the housing, plate which is controlled by an actuating device placing it in the high position for cleaning carpets or rugs or in the low position for cleaning hard floors.

Ce type de suceur connu n'est pas conçu pour le nettoyage des sols durs mouillés, mais seulement pour le nettoyage des sols durs secs : carrelages, dalles, parquets ... de sorte que la brosse s'étend généralement sur tout le pourtour de la semelle et se déplace avec la platine mobile, pour reposer sur le sol en position basse et être escamotée en position haute.This known type of nozzle is not designed for cleaning hard wet floors, but only for cleaning dry hard floors: tiles, slabs, parquet floors ... so that the brush generally extends around the entire periphery of the sole and moves with the movable plate, to rest on the ground in the low position and be retracted in the high position.

Lorsque le sol est mouillé, il est nécessaire d'en enlever l'eau et la présente invention vise ce but en procédant par raclage et aspiration.When the ground is wet, it is necessary to remove the water and the present invention aims at this object by proceeding by scraping and suction.

Dans ce but et conformément à l'invention, un dispositif racleur en matière souple est monté sur la platine du côté du canal opposé à celui où se trouve une partie rectiligne de la brosse, le dispositif racleur s'étendant parallèlement à la brosse jusqu'à un niveau situé légèrement en-dessous de celui de ladite brosse pour que ce dispositif fléchisse et découvre des passages à emprunter par l'eau raclée.For this purpose and in accordance with the invention, a scraper device made of flexible material is mounted on the plate on the side of the channel opposite to that where there is a straight part of the brush, the scraper device extending parallel to the brush up to at a level located slightly below that of said brush so that this device flexes and discovers passages to be taken by the scraped water.

La brosse rectiligne, avant ou arrière, est prolongée par des parties latérales pour former une brosse conformée en U.The rectilinear brush, front or rear, is extended by lateral parts to form a U-shaped brush.

Suivant une première forme de réalisation dite à simple effet, le dispositif racleur est situé à l'arrière du canal et constitué par une lame monolithique présentant en creux sur la face arrière des saignées verticales qui débouchent vers le bas, ainsi que vers l'avant pour laisser passer l'eau lorsque le suceur étant tiré vers l'arrière avec la platine en position basse, la lame est couchée vers l'avant et repose sur le sol en délimitant des passages par les crêtes de nervures séparant les saignées.According to a first embodiment known as a single effect, the scraper device is located at the rear of the channel and consists of a monolithic blade having recessed on the rear face of the vertical grooves which open downward, as well as forward to let the water pass when the squeegee is pulled back with the plate in the low position, the blade is laid forward and rests on the ground, delimiting passages through the ridges of ribs separating the grooves.

Selon une variante particulièrement avantageuse, la lame est inclinée vers le bas et vers l'avant.According to a particularly advantageous variant, the blade is inclined downward and forward.

Suivant une deuxième forme de réalisation dite à double effet, le dispositif racleur, qu'il soit situé à l'arrière ou à l'avant du canal, est constitué par deux alignements de volets parallèles l'un à l'autre, les volets d'un alignement étant séparés les uns des autres par des passages situés en regard de volets de l'autre alignement de façon que la "vague" raclée sur le sol par les volets en marche avant soit avalée par le canal aspirant sans possibilité de s'échapper vers l'arrière par les passages en quinconce, alors que la "vague" raclée sur le sol en marche arrière est aspirée vers l'avant par ledit canal à travers lesdits passages en quinconce.According to a second so-called double-acting embodiment, the scraper device, whether located at the rear or at the front of the channel, consists of two alignments of flaps parallel to each other, the flaps of an alignment being separated from each other by passages located opposite flaps of the other alignment so that the "wave" scraped on the ground by the flaps in forward direction is swallowed by the suction channel without the possibility of s 'escape backwards through the staggered passages, while the "wave" scraped on the ground in reverse is sucked forward by said channel through said staggered passages.

Quelle que soit la forme de réalisation retenue, elle peut également améliorer l'arrachage des fils. A cet effet le bord inférieur du dispositif racleur s'étend au niveau ou au-dessus du plan de glissement de la semelle et à faible distance.Whatever the embodiment chosen, it can also improve the pulling of the wires. For this purpose the lower edge of the scraper device extends at or above the sliding plane of the sole and at a short distance.

Divers autres caractéristiques et avantages de l'invention ressortent d'ailleurs de la description détaillée qui suit.Various other characteristics and advantages of the invention will also emerge from the detailed description which follows.

Des formes de réalisation de l'objet de l'invention sont représentées, à titre d'exemples non limitatifs, sur le dessin annexe.Embodiments of the object of the invention are shown, by way of nonlimiting examples, in the accompanying drawing.

Sur ce dessin :

  • - la figure 1 est une coupe longitudinale illustrant une première forme de réalisation du suceur et prise suivant la ligne I-I de la figure 2, sans semelle sur la moitié gauche,
  • - la figure 2 est une vue en plan de dessous prise suivant la ligne II-II de la figure 1,
  • - les figures 3 et 4 sont des coupes transversales prises suivant la ligne III-III de la figure 1 et montrant la platine en position rentrée et respectivement en position sortie,
  • - la figure 5 est une vue analogue à la figure 3 illustrant une deuxième forme de réalisation du suceur,
  • - la figure 6 est une vue partielle analogue à la figure 2, prise suivant la ligne VI-VI de la figure 5.
  • - la figure 7 est une vue analogue à la figure 5 illustrant une troisième forme de réalisation du suceur.
On this drawing :
  • FIG. 1 is a longitudinal section illustrating a first embodiment of the nozzle and taken along line II of FIG. 2, without a sole on the left half,
  • FIG. 2 is a bottom plan view taken along line II-II of FIG. 1,
  • FIGS. 3 and 4 are transverse sections taken along line III-III of FIG. 1 and showing the plate in the retracted position and respectively in the extended position,
  • - Figure 5 is a view similar to Figure 3 illustrating a second embodiment of the nozzle,
  • - Figure 6 is a partial view similar to Figure 2, taken along the line VI-VI of Figure 5.
  • - Figure 7 is a view similar to Figure 5 illustrating a third embodiment of the nozzle.

Ainsi que cela ressort des figures 1 à 4, le suceur comporte un boîtier 1 en matière plastique faisant corps, à sa partie supérieure arrière, avec un manchon 2 dans lequel une tubulure d'aspiration 3 est montée tournante avec étanchéité autour d'un axe antéro-postérieur sensiblement horizontal. Cette tubulure 32 débouche dans une cheminée 4 communiquant, à travers un passage 5, avec un canal 6 d'une semelle métallique 7 fixée dans le boîtier 1. Cette semelle est destinée à glisser sur le sol par des patins 8 délimitant entre eux le canal 6 précité.As is apparent from Figures 1 to 4, the nozzle comprises a housing 1 made of plastic forming a body, at its rear upper part, with a sleeve 2 in which a suction pipe 3 is rotatably mounted with sealing around an axis substantially horizontal anteroposterior. This tubing 32 opens into a chimney 4 communicating, through a passage 5, with a channel 6 of a metal sole 7 fixed in the housing 1. This sole is intended to slide on the ground by pads 8 delimiting between them the channel 6 cited above.

Bien entendu, le boîtier 1 peut faire corps avec la tubulure d'aspiration 3 ou bien celle-ci peut être montée tournante relativement au boîtier autour non seulement d'un axe antéro-postérieur mais également d'un axe transversal. Dans ce dernier cas, le suceur peut coopérer avec un galet postérieur d'appui et plus particulièrement il peut être du type flottant décrit dans le brevet français n° 2.546.054.Of course, the housing 1 can be integral with the suction tube 3 or it can be rotatably mounted relative to the housing around not only an anteroposterior axis but also a transverse axis. In the latter case, the squeegee can cooperate with a rear support roller and more particularly it can be of the floating type described in French patent No. 2,546,054.

Le boîtier 1 contient, au-dessus de la semelle 7, une platine 9 susceptible d'occuper deux positions illustrées par les figures 3 et 4. La platine 9 est maintenue en position haute, dite position rentrée d'escamotage (figure 3), par des ressorts hélicoïdaux coniques 10 interposés entre la semelle 7 et elle-même, ces ressorts étant enfilés sur des tiges 11 de guidage de ladite platine en translation verticale, lui permettant de se déplacer parallèlement à elle-même. La platine 9 est commandée en translation vers la position basse dite position sortie d'intervention (figure 4) et verrouillée dans cette position, par des tourillons extrêmes 12 d'une bielle de transmission 13 traversant des leviers 15 de deux pédales d'actionnement 16, 17 articulées au moyen de pivots 18 dans le boîtier. Dans l'exemple représenté, les tourillons 12 portent directement sur des rampes inclinées 14 faisant corps avec la platine 9 et se terminant par des crans hauts 19 de verrouillage.The housing 1 contains, above the sole 7, a plate 9 capable of occupying two positions illustrated by FIGS. 3 and 4. The plate 9 is held in the high position, called the retracted retracted position (FIG. 3), by conical helical springs 10 interposed between the sole 7 and itself, these springs being threaded on rods 11 for guiding said plate in vertical translation, allowing it to move parallel to itself. The plate 9 is controlled in translation towards the low position called the intervention output position (FIG. 4) and locked in this position, by end pins 12 of a transmission rod 13 passing through levers 15 of two actuating pedals 16 , 17 articulated by means of pivots 18 in the housing. In the example shown, the pins 12 bear directly on ramps inclined 14 integral with the plate 9 and ending in high notches 19 for locking.

Une fente périphérique 20 est ménagée entre la femelle 7 et le boîtier 1 pour le passage d'organes de nettoyage sur sol dur. Ces organes comportent une brosse linéaire 21 dite "strip" qui, dans l'exemple représenté, est conformée en U ; elle présente une partie faciale 22 s'étendant devant le canal 6 et prolongée par des parties latérales 23, 24. Les poils de cette brosse 21 sont fixés dans une monture 25 insérée dans une glissière 26 de la platine 9.A peripheral slot 20 is formed between the female 7 and the housing 1 for the passage of cleaning members on hard ground. These members include a linear brush 21 called "strip" which, in the example shown, is shaped like a U; it has a facial part 22 extending in front of the channel 6 and extended by lateral parts 23, 24. The bristles of this brush 21 are fixed in a frame 25 inserted in a slide 26 of the plate 9.

Les organes de nettoyage comportent, outre la brosse 21, un dispositif racleur 27 constitué par une matière souple telle qu'un caoutchouc ou autre élastomère. Ce dispositif dont deux formes de réalisation sont décrites dans ce qui suit, s'étend parallèlement à la partie faciale 22 de la brosse 21 et est située de l'autre côté du canal 6. Le dispositif racleur 27 fait corps avec une réglette 28 insérée dans la glissière 26 de la platine 9.The cleaning members comprise, in addition to the brush 21, a scraper device 27 constituted by a flexible material such as a rubber or other elastomer. This device, two embodiments of which are described in the following, extends parallel to the facial part 22 of the brush 21 and is located on the other side of the channel 6. The scraper device 27 is integral with a strip 28 inserted in the slide 26 of the plate 9.

Suivant la première forme de réalisation illustrée par les figures 1 à 4, la partie 22 de la brosse est située à l'avant et le dispositif racleur 27 à l'arrière. Ce dispositif racleur est constitué par une lame monolithique 29 présentant en creux, face à l'arrière, des saignées verticales 30 séparées par des nervures 31 profilées en V. Les saignées débouchent en bas.According to the first embodiment illustrated in Figures 1 to 4, the part 22 of the brush is located at the front and the scraper device 27 at the rear. This scraper device consists of a monolithic blade 29 having in hollow, facing the rear, vertical grooves 30 separated by ribs 31 profiled in V. The grooves open at the bottom.

Comme le montre la figure 3, le bord libre 32 de la lame 29 au repos est situé à un niveau légèrement plus bas que celui de la brosse 21. Par exemple, lorsque la platine 9 est escamotée (figure 3), ce bord 32 est situé à d = 3 mm de la surface de glissement 33 de la semelle 7, alors que la brosse 21 en est éloignée de D = 7 mm et peut descendre de 12 mm. En fonction de la souplesse de la lame et de sa conformation, d peut être compris entre 1 et 4 mm, alors que D est compris entre 5 et 8 mm.As shown in Figure 3, the free edge 32 of the blade 29 at rest is located at a slightly lower level than that of the brush 21. For example, when the plate 9 is retracted (Figure 3), this edge 32 is located at d = 3 mm from the sliding surface 33 of the sole 7, while the brush 21 is distant from D = 7 mm and can descend by 12 mm. Depending on the flexibility of the blade and its conformation, d can be between 1 and 4 mm, while D is between 5 and 8 mm.

Comme le montre la figure 4, lorsque la brosse 21 repose sur le sol 34 dont la semelle 7 est écartée de E = 5 mm dans l'exemple choisi, la lame 29 est incurvée.As shown in Figure 4, when the brush 21 rests on the ground 34 whose sole 7 is spaced E = 5 mm in the example chosen, the blade 29 is curved.

Si le suceur est déplacé vers l'arrière dans le sens de la flèche F, ladite lame 29 est couchée vers l'avant (représentation en trait plein) et repose sur le sol 34 par les crêtes de ses nervures 31. L'eau se trouvant sur ledit sol n'est alors pas raclée mais reste sur place en empruntant les passages délimités de part et d'autre desdites nervures par les saignées 30 et le sol.If the squeegee is moved backwards in the direction of arrow F, said blade 29 is lying forward (solid line representation) and rests on the ground 34 by the ridges of its ribs 31. The water being on said ground is then not scraped but remains on place using the passages delimited on either side of said ribs by the grooves 30 and the ground.

Par contre, si le suceur est déplacé vers l'avant dans le sens opposé à celui de la flèche F, la lame 29 est couchée vers l'arrière (représentation en trait mixte) et repose sur le sol 34 par le bord rectiligne 32 de sa face avant. L'eau se trouvant sur ledit sol est donc raclée et forme une "vague" vers l'avant qui se trouve aspirée.On the other hand, if the squeegee is moved forwards in the direction opposite to that of arrow F, the blade 29 is laid backwards (representation in phantom) and rests on the ground 34 by the straight edge 32 of its front side. The water on said ground is therefore scraped and forms a "wave" towards the front which is sucked.

Suivant une variante représentée en trait mixte sur la figure 3, la lame 29 au repos, au lieu d'être verticale, est inclinée vers le bas et vers l'avant lorsqu'elle est au repos. Cette inclinaison permet de favoriser l'incurvation de la lame en marche arrière pour ne pas racler l'eau et de raidir la lame incurvée en marche avant pour mieux racler l'eau.According to a variant shown in phantom in Figure 3, the blade 29 at rest, instead of being vertical, is inclined downward and forward when it is at rest. This inclination makes it possible to favor the curving of the blade in reverse so as not to scrape the water and to stiffen the curved blade in forward to better scrape the water.

Suivant une deuxième forme de réalisation illustrée par les figures 5 et 6, la partie 22 de la brosse est toujours située à l'avant et le dispositif racleur 27 à l'arrière. Ce dispositif racleur comporte deux alignements sensiblement parallèles de volets 35 et 36 faisant corps avec la réglette 28 montée dans la platine. Les volets 35 sont séparés les uns des autres par des passages 37 et les volets 36 par des passages 38. Les volets 36 du deuxième alignement sont situés en regard des passages 37 du premier alignement. Dès lors, les passages 37 et 38 sont répartis en quiconce et communiquent entre eux par le couloir 39 ménagé entre les deux alignements.According to a second embodiment illustrated in Figures 5 and 6, the part 22 of the brush is always located at the front and the scraper device 27 at the rear. This scraper device comprises two substantially parallel alignments of flaps 35 and 36 forming one body with the strip 28 mounted in the plate. The flaps 35 are separated from each other by passages 37 and the flaps 36 by passages 38. The flaps 36 of the second alignment are located opposite the passages 37 of the first alignment. Consequently, the passages 37 and 38 are distributed in a staggered fashion and communicate with each other by the passage 39 formed between the two alignments.

Dans cette deuxième forme de réalisation, les volets 35, 36 et la réglette 28 sont relativement raides. Les faces antérieure et postérieure de ces volets sont planes. Les bords inférieurs desdits volets sont rectilignes et situés à un niveau légèrement inférieur à celui de la brosse 21 ; cependant, la distance "e" (figure 5) de ces niveaux est réduite de façon que les volets 35, 36 fléchissent à peine lors du déplacement du suceur en marche avant ou en marche arrière ; elle peut même être égale à zéro.In this second embodiment, the flaps 35, 36 and the strip 28 are relatively stiff. The front and rear faces of these flaps are flat. The lower edges of said flaps are rectilinear and situated at a level slightly lower than that of the brush 21; however, the distance "e" (FIG. 5) from these levels is reduced so that the flaps 35, 36 barely bend when moving the squeegee forward or reverse; it can even be zero.

Ce type de dispositif racle et aspire l'eau dans les deux sens.This type of device scrapes and draws water in both directions.

En effet, en marche avant dans le sens opposé à celui de la flèche F, les volets antérieurs 35 raclent et refoulent la vague d'eau vers l'avant où elle est aspirée ; au droit des passages 37, l'eau reste en place, mais les volets postérieurs 36 la raclent et la refoulent vers l'avant, l'aspiration favorisant ce refoulement et avalant l'eau.Indeed, in forward direction in the opposite direction to that of arrow F, the front flaps 35 scrape and push back the wave of water forward where it is sucked; in line with the passages 37, the water remains in place, but the rear flaps 36 scrape it and discharge it forward, the suction favoring this discharge and swallowing the water.

En marche arrière dans le sens de la flèche F, les volets postérieurs 36 raclent l'eau qui forme une "vague", laquelle est aspirée à travers les passages 38 et 37 en quinconce en suivant un cheminement opposé au déplacement.In reverse in the direction of arrow F, the rear flaps 36 scrape the water which forms a "wave", which is sucked through the passages 38 and 37 in staggered rows following a path opposite to the movement.

Dans cette deuxième forme de réalisation, la disposition en quinconce des volets et des passages permet de racler l'eau sur le sol et de l'enlever, lorsque le suceur est tiré ou poussé, en ligne droite ou en zig-zag, du fait que l'aspiration combine ses effets avec les volets de raclage grâce à la présence des passages à travers lesquels ladite aspiration intervient.In this second embodiment, the staggered arrangement of the flaps and passages makes it possible to scrape the water off the ground and to remove it, when the nozzle is pulled or pushed, in a straight line or in a zig-zag, because that the suction combines its effects with the scraping flaps thanks to the presence of the passages through which the said suction intervenes.

Une troisième forme de réalisation illustrée par la figure 7 est applicable en particulier au suceur flottant faisant l'objet du brevet français n° 2.546.054.A third embodiment illustrated in FIG. 7 is applicable in particular to the floating nozzle which is the subject of French patent n ° 2.546.054.

Ce suceur est identique à celui décrit en se référant aux figures 1 à 5, aux seules différences près que le boîtier 1 ne fait pas corps dans ce cas avec le manchon 2. En effet, une buse basculante 40 est montée pivotante autour d'un axe transversal 41 du boîtier et son conduit interne 42 débouche dans la cheminée 4. Le manchon 2 dans lequel la tubulure d'aspiration 3 est montée tournante autour d'un axe longitudinal antéro-postérieur est monté pivotant sur la buse basculante 40 autour d'un axe transversal 43 situé entre l'axe 41 précité et un axe 44 autour duquel un galet 45 est monté tournant. L'axe 44 est porté par la buse 40 en arrière du boîtier 1 et en bas. Ainsi, le boîtier 1, la semelle 7, la platine 9, la brosse 21 et la raclette 27 forment un ensemble flottant.This nozzle is identical to that described with reference to Figures 1 to 5, with the only differences that the housing 1 is not integral in this case with the sleeve 2. Indeed, a tilting nozzle 40 is pivotally mounted around a transverse axis 41 of the housing and its internal duct 42 opens into the chimney 4. The sleeve 2 in which the suction pipe 3 is mounted to rotate about an anteroposterior longitudinal axis is pivotally mounted on the tilting nozzle 40 around a transverse axis 43 located between the aforementioned axis 41 and an axis 44 around which a roller 45 is mounted to rotate. The axis 44 is carried by the nozzle 40 behind the housing 1 and at the bottom. Thus, the housing 1, the sole 7, the plate 9, the brush 21 and the squeegee 27 form an assembly floating.

Dans cette troisième forme de réalisation, la brosse 21 conformée en U est symétrique de la précédente, étant donné que sa partie faciale 22 est maintenant située à l'arrière. Dès lors, le dispositif racleur 27 à volets 35, 36 et passages quinconcés 37, 38, 39 est monté dans la platine 9 à l'avant ; il fonctionne de la même façon que cela est exposé dans ce qui précède pour la deuxième forme de réalisation. Il présente en outre l'avantage d'être manoeuvrable de façon sensitive.In this third embodiment, the brush 21 shaped into a U is symmetrical to the previous one, since its facial part 22 is now located at the rear. Consequently, the scraper device 27 with flaps 35, 36 and staggered passages 37, 38, 39 is mounted in the plate 9 at the front; it operates in the same way as set forth in the above for the second embodiment. It also has the advantage of being sensitive to maneuverability.

Quelle que soit la forme de réalisation retenue, il est important de remarquer que dans la position rentrée d'escamotage (figures 3 et 5) utilisée pour le nettoyage des tapis et moquettes, le dispositif racleur 27 peut être utilisé comme arrache-fil, à condition cependant que son bord inférieur soit situé à faible distance et au-dessus du plan de glissement 33 de la semelle 7. Cette distance d est avantageusement comprise entre 1 et 3 mm.Whatever the embodiment chosen, it is important to note that in the retracted retracted position (FIGS. 3 and 5) used for cleaning carpets and rugs, the scraper device 27 can be used as a thread puller, provided, however, that its lower edge is located at a short distance and above the sliding plane 33 of the sole 7. This distance d is advantageously between 1 and 3 mm.
