Definitions
- the present invention relates to a vacuum cleaner for carpets and rugs, dry hard floors and wet hard floors.
- a first known type of 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 mobile plate fitted with a brush passing through a slot made between the sole 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.
- This known nozzle is not designed for cleaning hard wet floors, but only for cleaning dry hard floors: tiles, tiles, parquet ... so that the brush generally extends around the entire periphery of the sole. and moves with the mobile stage, to rest on the ground in the low position and be retracted in the high position.
- a second known type of nozzle is described in European patent application No. 0 158 145. It comprises a housing integral with a bent duct, the rear upper end of which is connected to a suction pipe and the lower end of which is median opens through an opening in a transverse suction channel from below the housing. Two brushes extending parallel to this channel are guided in vertical translation on either side of the bent conduit and are moved by a transverse slide to occupy several positions. The slide guided in horizontal translation in the housing can be moved, to select the position of the brushes, by the user. To this end, it acts on a pusher of said slide which passes through the housing and projects outside.
- a flexible blade is fixed under the housing between the brushes to come into contact with the ground or a carpet when the brushes are retracted or in low projection, the blade having the function of increasing the speed of the air at l entry of the squeegee.
- the present invention aims at this object by perfecting the nozzle of the first type.
- 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 to a level located slightly below that of said brush so that, the plate being in the low position, the device flexes in the direction opposite to that of the displacement of the squeegee and delimits passages through which the water which is not scraped travels.
- the rectilinear brush, front or rear, is extended by lateral parts to form a U-shaped brush.
- 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.
- the blade is inclined downward and forward.
- 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 in staggered passages, while the "wave” scraped on the ground in reverse is sucked forward by said channel through said passages staggered.
- the lower edge of the scraper device extends at or above the sliding plane of the sole and at a short distance.
- the squeegee comprises a housing 1 made of plastic forming a body, at its upper rear part, with a sleeve 2 in which a suction tube 3 is mounted to rotate 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.
- 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.
- 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.
- 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.
- the pins 12 bear directly on inclined ramps 14 integral with the plate 9 and ending in high notches 19 for locking.
- a peripheral slot 20 is formed between the sole 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.
- 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 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.
- 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.
- the free edge 32 of the blade 29 at rest is located at a slightly lower level than that of the brush 21.
- d can be between 1 and 4 mm, while D is between 5 and 8 mm.
- the blade 29 at rest instead of being vertical, is tilted down and forward when 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.
- 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.
- 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" ( Figure 5) of these levels is reduced so that the flaps 35, 36 barely bend when moving the squeegee in forward or reverse; it can even be zero.
- This type of device scrapes and draws water in both directions.
- 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.
- 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.
- 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.
- a tilting nozzle 40 is pivotally mounted around a transverse axis 41 of the housing and its internal conduit 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.
- the housing 1, the sole 7, the plate 9, the brush 21 and the squeegee 27 form a floating assembly.
- 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.
- the scraper device 27 can be used as a thread puller, provided however that its lower edge is located at low distance and above the sliding plane 33 of the sole 7. This distance d is advantageously between 1 and 3 mm.

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 premier type de suceur connu 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.A first known type of 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 mobile plate fitted with a brush passing through a slot made between the sole 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 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 nozzle is not designed for cleaning hard wet floors, but only for cleaning dry hard floors: tiles, tiles, parquet ... so that the brush generally extends around the entire periphery of the sole. and moves with the mobile stage, to rest on the ground in the low position and be retracted in the high position.
Un deuxième type de suceur connu est décrit dans la demande de brevet européen n° 0 158 145. Il comprend un boîtier faisant corps avec un conduit coudé dont l'extrémité supérieure arrière est raccordée à une tubulure d'aspiration et dont l'extrémité inférieure médiane débouche par une ouverture dans un canal aspirant transversal du dessous du boîtier. Deux brosses s'étendant parallèlement à ce canal sont guidées en translation verticale de part et d'autre du conduit coudé et sont mûes par une coulisse transversale pour occuper plusieurs positions. La coulisse guidée en translation horizontale dans le boîtier, peut être déplacée, pour sélectionner la position des brosses, par l'utilisateur. A cet effet, celui-ci agit sur un poussoir de ladite coulisse qui traverse le boîtier et en fait saillie à l'extérieur.A second known type of nozzle is described in European patent application No. 0 158 145. It comprises a housing integral with a bent duct, the rear upper end of which is connected to a suction pipe and the lower end of which is median opens through an opening in a transverse suction channel from below the housing. Two brushes extending parallel to this channel are guided in vertical translation on either side of the bent conduit and are moved by a transverse slide to occupy several positions. The slide guided in horizontal translation in the housing can be moved, to select the position of the brushes, by the user. To this end, it acts on a pusher of said slide which passes through the housing and projects outside.
Par ailleurs, une lame souple est fixée sous le boîtier entre les brosses pour venir en contact avec le sol ou un tapis lorsque les brosses sont escamotées ou en faible saillie, la lame ayant pour fonction d'accroître la vitesse de l'air à l'entrée du suceur.In addition, a flexible blade is fixed under the housing between the brushes to come into contact with the ground or a carpet when the brushes are retracted or in low projection, the blade having the function of increasing the speed of the air at l entry of the squeegee.
Lorsque le sol est mouillé, il est nécessaire d'en enlever l'eau, ce que ne permettent ni le suceur du premier type, ni celui du deuxième type.When the soil is wet, it is necessary to remove the water, which neither the nozzle of the first type nor that of the second type allows.
La présente invention vise ce but en perfectionnant le suceur du premier type.The present invention aims at this object by perfecting the nozzle of the first type.
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, la platine étant en position basse, le dispositif fléchisse en direction opposée à celle du déplacement du suceur et délimite des passages à travers lesquels l'eau qui n'est pas raclée chemine.According to 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 to a level located slightly below that of said brush so that, the plate being in the low position, the device flexes in the direction opposite to that of the displacement of the squeegee and delimits passages through which the water which is not scraped travels.
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-effect 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 in staggered passages, while the "wave" scraped on the ground in reverse is sucked forward by said channel through said passages staggered.
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 annexé.Embodiments of the object of the invention are shown, by way of nonlimiting examples, in the accompanying drawing.

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 can be seen from FIGS. 1 to 4, the squeegee comprises a
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
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
Une fente périphérique 20 est ménagée entre la semelle 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
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
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
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
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
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 rearward in the direction of arrow F, said
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
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
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
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
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
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
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
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
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.Whichever embodiment is chosen, it is important to note that in the retracted retracted position (FIGS. 3 and 5) used for cleaning carpets and rugs, the
Claims (6)
- Suction nozzle for carpets or for hard dry and damp floors, comprising, on the one hand, a casing (1) provided with a suction tube (3) and forming an integral part of a sole plate (7) which defines between runners (8) at least one channel (6) communicating by means of at least one passage (5) with the said tube and, on the other hand, a movable plate (9) provided with a brush (22) traversing a slot (20) formed between the sole plate and the casing, this plate being controlled by an actuating device (12) placing it in an upper position for cleaning carpets or in a lower position for cleaning hard floors, characterised in that a scraper (27) of flexible material is mounted on the plate (9) on the side of the channel (6) opposite the one at which a rectilinear portion of the brush (22) is situated, the scraper (27) extending parallel to the brush (22) to a level situated slightly below that of the said brush so that, when the plate is in the lower position, the device bends in the direction opposite to that of the displacement of the suction nozzle and defines passages (30; 37 to 39) through which any water not scraped passes.
- Suction nozzle according to claim 1, characterised in that the front or rear rectilinear brush is extended by lateral portions in order to form a U-shaped brush.
- Suction nozzle according to claim 1 or claim 2, characterised in that the scraper (27) is situated to the rear of the channel (6) and is formed by a monolithic blade (29) provided on its rear face with vertical recessed grooves (30) which open towards the bottom and towards the front to allow for the passage of water when, the suction nozzle being pulled towards the rear with the plate (9) in the lower position, the blade (29) is laid down towards the front and rests on the floor, thereby defining passages by means of the crests of ridges (31) separating the grooves (30).
- Suction nozzle according to claim 3, characterised in that the blade (29) is inclined towards the bottom and towards the front at rest.
- Suction nozzle according to claim 1 or claim 2, characterised in that the scraper (27), irrespective of whether it is situated to the rear of or in front of the channel (6), is formed by two rows of flaps substantially parallel to one another, the flaps (35; 36) of one row being separated from one another by passages (37; 38) situated opposite flaps (36; 35) of the other row so that the "wave" scraped from the floor by the flaps in forward motion is swallowed up by the suction channel (6) and cannot escape towards the rear via the staggered passages, while the "wave" scraped from the floor during the rearward motion is drawn towards the front via the said channel through the said staggered passages.
- Suction nozzle according to any one of claims 1 to 5, characterised in that, in order to strip the threads of a carpet, the lower edge (32) of the scraper (27) extends at the level of or above the sliding plane (33) of the sole plate (7) and at a short distance therefrom.
