Description

La présente invention concerne un suceur d'aspirateur comprenant un boítier susceptible d'être raccordé, vers le haut et vers l'arrière, à une tubulure d'aspiration par l'intermédiaire d'un manchon de raccordement pivotant, une semelle qui est située sous le boítier et qui présente un canal d'aspiration, des roues disposées vers l'arrière du suceur et un organe racleur avant, disposé vers l'avant de la semelle par rapport auxdites roues arrière, cet organe racleur étant fixe et faisant continuellement saillie sous la semelle, l'axe de pivotement du manchon étant situé en arrière de l'axe de rotation desdites roues ou coïncidant avec cet axe de rotation.The present invention relates to a vacuum cleaner nozzle comprising a box capable of being connected, upwards and backwards, to a suction pipe via a connection sleeve swivel, a sole which is located under the housing and which has a suction channel, wheels arranged towards the rear of the nozzle and a front scraper member, disposed towards the front of the sole in relation to to said rear wheels, this scraper member being fixed and forming continuously protruding under the sole, the pivot axis of the sleeve being situated behind the axis of rotation of said wheels or coinciding with this axis of rotation.

Un suceur d'aspirateur de ce type est connu par la demande de brevet PCT WO 99/34 721. L'organe racleur avant est fixe et reste constamment en position active, de sorte qu'il est efficace en permanence. En raison de la position de l'axe de pivotement du manchon par rapport à celui des roues, le suceur est du type "à corps flottant".A vacuum cleaner nozzle of this type is known from the application for PCT patent WO 99/34 721. The front scraper member is fixed and remains constantly in active position, so it is effective in permanence. Due to the position of the sleeve pivot axis compared to that of the wheels, the nozzle is of the "floating body" type.

Ce système donne toute satisfaction sur le plan de la qualité d'aspiration, tant sur un sol "dur", du type carrelage ou parquet, ou que sur un sol du type tapis ou moquette.This system gives full satisfaction in terms of quality suction, both on a "hard" floor, such as tiles or parquet, or on a carpet or carpet type floor.

Toutefois, la Société Demanderesse s'est aperçue que, sur certains types de sols durs, relativement fragiles, il existe éventuellement un risque que les roues du suceur au contact avec le sol laissent des traces sur ce dernier. De plus, il arrive que l'utilisateur ou l'utilisatrice exerce une pression verticale trop forte sur la tubulure d'aspiration, cette pression se répercutant sur les roues, ce qui augmente ce risque.However, the Applicant Company has noticed that, on certain types of hard, relatively fragile soils, there may be a risk that the squeegee wheels in contact with the ground leave traces on this latest. In addition, the user may sometimes exercise vertical pressure too strong on the suction pipe, this pressure is repercussion on the wheels, which increases this risk.

Lorsque l'on déplace le suceur sur le sol selon une trajectoire ayant des virages très serrés, ce déplacement est parfois obtenu en imprimant un mouvement latéral, transversal au sens naturel antéro-postérieur de roulement. Ce faisant, le contact entre le sol et les roues (au moins pour la roue intérieure au virage) n'est plus un contact de roulement mais de glissement relatif. Les roues sont généralement réalisées en matière plastique et, lorsque cette matière est relativement dure, un tel glissement pourrait laisser des traces de patinage sur le sol, par exemple pour un sol ciré.When the squeegee is moved on the ground along a trajectory having very tight turns, this displacement is sometimes obtained by printing a lateral, transverse movement in the anteroposterior natural sense of rolling. In doing so, the contact between the ground and the wheels (at least for the inner wheel at the bend) is no longer a rolling contact but relative slip. The wheels are generally made of material plastic and, when this material is relatively hard, such slippage could leave traces of skating on the ground, for example for a ground wax.

L'invention a pour but de remédier aux inconvénients précités.The invention aims to remedy the aforementioned drawbacks.

Ce but est atteint grâce au fait que le suceur de l'invention comporte en outre un organe racleur arrière, situé au voisinage des roues arrière, et des moyens de commande dudit organe racleur arrière, situés vers l'arrière du suceur, ces moyens étant aptes à commander l'organe racleur arrière entre une position inactive, dans laquelle le suceur est apte à reposer sur le sol par les roues arrière et par l'organe racleur avant, et une position active dans laquelle ledit organe racleur arrière fait saillie par rapport aux roues arrière de telle sorte que le suceur est apte à reposer sur le sol par les organes racleurs avant et arrière.This object is achieved thanks to the fact that the nozzle of the invention further includes a rear scraper member, located in the vicinity of the wheels rear, and control means of said rear scraper member, located towards the rear of the nozzle, these means being able to control the organ rear scraper between an inactive position, in which the squeegee is suitable to rest on the ground by the rear wheels and by the front scraper member, and an active position in which said rear scraper member projects compared to the rear wheels so that the squeegee is able to rest on the ground by the front and rear scraper members.

Par "organe racleur", on entend désigner tout organe tel qu'une brosse, par exemple du genre couramment dénommé "strips" par l'homme du métier ou, plus généralement, tout organe du type apte à coopérer avec le sol par un frottement pouvant aller du grattage d'une brosse jusqu'à un contact plus doux analogue à un lustrage doux. Par exemple, les organes racleurs avant et arrière peuvent être constitués par deux strips, de rigidités identiques ou différentes. L'organe racleur arrière contribue à l'effet de raclage, mais celui-ci est généralement correctement assuré par le seul organe racleur avant. Par conséquent, l'organe racleur arrière peut être plus souple et plus "doux" que l'organe racleur avant, en restant toutefois suffisamment rigide pour, dans sa position active, empêcher que les roues arrière ne reposent sur le sol.By "scraper organ" is meant any organ such as a brush, for example of the type commonly referred to as "strips" by a person skilled in the art or, more generally, any organ of the type capable of cooperate with the ground by friction that can range from the scraping of a brush until softer touch similar to soft buffing. Through example, the front and rear scraper members can be constituted by two strips, of identical or different rigidities. The rear scraper member contributes to the scraping effect, but this is generally correct provided by the only front scraper member. Therefore, the scraper member rear may be more flexible and "softer" than the front scraper member, remaining however rigid enough to, in its active position, prevent the rear wheels from resting on the ground.

L'organe racleur avant étant fixe, le suceur est de constitution simple et il est efficace sur tout type de sol. Seul l'organe racleur arrière est mobile. Dans la mesure où les moyens de commande de l'organe racleur arrière servent seulement à commander ce dernier et sont disposés à l'arrière du suceur, ils peuvent être réalisés de manière simple et peu encombrante. La commande de l'organe racleur arrière dans sa position active relève légèrement l'arrière du suceur par rapport au sol et place les roues hors de contact du sol. Ainsi, grâce à l'invention, il est possible de manière simple d'obtenir un suceur efficace dans toutes les situations sans aucun risque de rayures ou de traces de glissement sur un sol dur fragile.The front scraper member being fixed, the nozzle is of constitution simple and effective on any type of soil. Only the rear scraper member is mobile. Insofar as the control means of the organ rear scraper are used only to control the latter and are arranged at the rear of the squeegee, they can be made in a simple manner and space-saving. The control of the rear scraper member in its active position slightly raises the rear of the squeegee from the ground and place the wheels out of contact with the ground. Thus, thanks to the invention, it is possible in a simple way to obtain an effective nozzle in all situations without any risk of scratches or traces of slipping on a hard fragile soil.

Avantageusement, lorsque les roues arrière sont constituées par deux roues distinctes et espacées, l'organe racleur arrière est disposé entre lesdites roues arrière.Advantageously, when the rear wheels are constituted by two separate and spaced wheels, the rear scraper member is arranged between said rear wheels.

L'organe racleur arrière est alors logé dans l'espace naturellement ménagé entre les deux roues arrière. Sa présence ne nuit pas à la compacité du suceur et n'augmente que peu son prix de revient. The rear scraper member is then naturally housed in the space formed between the two rear wheels. Its presence does not harm the compactness of the squeegee and only slightly increases its cost price.

Selon une disposition avantageuse, l'organe racleur arrière est solidaire d'un bâti monté pivotant par rapport à la semelle du boítier, autour d'un axe parallèle à l'axe de pivotement du manchon.According to an advantageous arrangement, the rear scraper member is secured to a frame mounted to pivot relative to the sole of the housing, about an axis parallel to the pivot axis of the sleeve.

Des moyens de commande de l'organe racleur arrière comprennent alors des moyens pour faire pivoter ce bâti entre une première position angulaire dans laquelle il est logé dans l'épaisseur de la semelle et une deuxième épaisseur angulaire dans laquelle l'organe racleur arrière fait saillie sous la semelle.Control means for the rear scraper member include then means for pivoting this frame between a first position angular in which it is housed in the thickness of the sole and a second angular thickness in which the rear scraper member makes protrusion under the sole.

L'invention sera bien comprise et ses avantages apparaítront mieux à la lecture de la description détaillée qui suit, d'un mode de réalisation représenté à titre d'exemple non limitatif. La description se réfère aux dessins annexés sur lesquels :

  • les figures 1 et 2 sont deux vues en perspective, respectivement de dessus et de dessous du suceur,
  • la figure 3 est une vue en coupe antéro-postérieure, globalement prise dans le plan III-III de la figure 1, sur laquelle des parties arrachées et coupées selon un plan décalé permettent de mieux visualiser les moyens de commande de l'organe racleur arrière, et
  • la figure 4 est une vue en perpective illustrant l'organe racleur arrière et son mécanisme de commande.
The invention will be clearly understood and its advantages will appear better on reading the detailed description which follows, of an embodiment shown by way of nonlimiting example. The description refers to the accompanying drawings in which:
  • FIGS. 1 and 2 are two perspective views, respectively from above and from below of the nozzle,
  • Figure 3 is an anteroposterior sectional view, generally taken in the plane III-III of Figure 1, on which parts cut away and cut along an offset plane allow to better visualize the control means of the rear scraper member , and
  • Figure 4 is a perspective view illustrating the rear scraper member and its control mechanism.

Le suceur représenté sur les figures 1 et 2 comporte un boítier 10 susceptible, à l'aide d'un manchon de raccordement 12 dirigé vers le haut et vers l'arrière, d'être raccordé à une tubulure d'aspiration. Le suceur comporte également une semelle 14 située sous le boítier et munie d'une ouverture d'aspiration.The nozzle shown in Figures 1 and 2 includes a housing 10 susceptible, using a connection sleeve 12 directed upwards and backwards, to be connected to a suction pipe. The nozzle also includes a sole 14 located under the housing and provided with a suction opening.

Dans toute la suite, on considérera que le sens vers l'avant, indiqué par la flèche F, est celui qui va en s'éloignant du manchon de raccordement 12. Ce sens correspond naturellement au sens de poussée du suceur dans des conditions d'utilisation normale de ce dernier. Le sens vers l'arrière est le sens inverse. La direction longitudinale du suceur indiquée par la double flèche L, est perpendiculaire à cette direction antéro-postérieure.In the following, we will consider that the direction forward, indicated by the arrow F, is the one which goes away from the sleeve of connection 12. This direction naturally corresponds to the direction of thrust of the nozzle in normal conditions of use of the latter. Meaning backwards is the opposite direction. The longitudinal direction of the squeegee indicated by the double arrow L, is perpendicular to this direction anteroposterior.

Dans la semelle, une ouverture d'aspiration 16 est réalisée dans une portion centrale d'un canal d'aspiration 18 qui s'étend longitudinalement dans la partie avant de ladite semelle. La face inférieure de la semelle comporte deux bandes arrache-fils 20 et 22, respectivement disposées devant et derrière l'ouverture d'aspiration 16.In the soleplate, a suction opening 16 is made in a central portion of a suction channel 18 which extends longitudinally in the front part of said sole. The underside of the sole has two tear-off strips 20 and 22, respectively arranged in front of and behind the suction opening 16.

Le suceur comporte également des roues arrière, respectivement 24 et 26 montées en rotation autour d'un axe longitudinal indiqué par la référence A sur la figure 3. Sur la même figure, on a indiqué par la référence B l'axe longitudinal de pivotement du manchon de raccordement 12, qui est en arrière de l'axe A.The squeegee also has rear wheels, respectively 24 and 26 mounted in rotation around a longitudinal axis indicated by the reference A in FIG. 3. In the same figure, we have indicated by reference B the longitudinal pivot axis of the connection sleeve 12, which is behind axis A.

Le suceur comporte encore un organe racleur avant 28, qui fait saillie sous la semelle 14. Cet organe racleur est situé vers l'avant de la semelle. Plus précisément, il est situé en avant du bord arrière 16A de l'ouverture d'aspiration 16. De manière avantageuse, comme dans l'exemple représenté, l'organe racleur 28 s'étend dans le canal d'aspiration 18. Il est alors interrompu dans la région de l'ouverture d'aspiration 16.The squeegee also has a front scraper member 28, which protrusion under the sole 14. This scraper member is located towards the front of the sole. More specifically, it is located in front of the rear edge 16A of the suction opening 16. Advantageously, as in the example shown, the scraper member 28 extends in the channel suction 18. It is then interrupted in the region of the opening suction 16.

Le suceur comporte encore un organe racleur arrière 30 qui est situé dans une partie arrière de la semelle.The squeegee further comprises a rear scraper member 30 which is located in a rear part of the sole.

Sur la figure 2, on voit cet organe racleur arrière dans sa position inactive, dans laquelle il est logé dans l'épaisseur de la semelle 14. Un renfoncement 32 est en effet ménagé dans cette semelle. L'organe racleur arrière 30 est situé au voisinage des roues arrière 24 et 26. Il s'étend avantageusement dans un espace de la semelle ménagé entre les deux roues arrière 24 et 26.In Figure 2, we see this rear scraper member in its position inactive, in which it is housed in the thickness of the sole 14. A recess 32 is in fact formed in this sole. The organ rear scraper 30 is located in the vicinity of the rear wheels 24 and 26. It advantageously extends into a space in the sole between the two rear wheels 24 and 26.

Par exemple, la semelle 14 est formée en une seule pièce avec une portion de raccordement 14A de cette semelle qui s'étend dans sa partie arrière. Cette portion 14A est délimitée par des joues latérales, respectivement 15A et 15B.For example, the sole 14 is formed in one piece with a connection portion 14A of this sole which extends in its rear part. This portion 14A is delimited by lateral cheeks, 15A and 15B respectively.

Les roues 24 et 26 sont raccordées aux faces extérieures de ces joues 15A et 15B. Le manchon de raccordement 12 est quant à lui disposé entre les joues 15A et 15B, mais du côté supérieur de la semelle, dans le conduit d'aspiration d'air séparé de la face inférieure de la semelle par un élément de paroi 15C. L'organe racleur arrière 30 est également disposé entre les joues 15A et 15B, mais sous la semelle, c'est-à-dire sous l'élément de paroi 15C précité, qui délimite le renfoncement 32.The wheels 24 and 26 are connected to the external faces of these cheeks 15A and 15B. The connection sleeve 12 is disposed between the cheeks 15A and 15B, but on the upper side of the sole, in the air intake duct separated from the underside of the soleplate by a wall element 15C. The rear scraper member 30 is also disposed between the cheeks 15A and 15B, but under the sole, that is to say under the aforementioned wall element 15C, which delimits the recess 32.

On voit sur la figure 2 que l'organe racleur arrière 30 est solidaire d'un bâti 34 qui est monté pivotant par rapport à la semelle 14, autour d'un axe C s'étendant longitudinalement, c'est-à-dire parallèlement aux axes A et B précités.We see in Figure 2 that the rear scraper member 30 is integral a frame 34 which is pivotally mounted relative to the sole 14, around a axis C extending longitudinally, i.e. parallel to axes A and B above.

On voit que ce bâti a sensiblement la forme d'un U dont les ailes 34A et 34B sont respectivement disposées contre les faces intérieures des joues 15A et 15B.We see that this frame has substantially the shape of a U whose wings 34A and 34B are respectively arranged against the interior faces cheeks 15A and 15B.

Des moyens de commande de l'organe racleur arrière 30 entre ses deux positions sont disposés vers l'arrière du boítier 10. Ils comportent une pédale de commande 36 montée pivotante autour d'un axe D. Par exemple, l'axe D est matérialisé par deux tétons 37A et 37B, disposés de chaque côté de la pédale.Control means for the rear scraper member 30 between its two positions are arranged towards the rear of the housing 10. They comprise a control pedal 36 pivotally mounted about an axis D. By example, axis D is materialized by two pins 37A and 37B, arranged with each side of the pedal.

Le téton 37A est introduit dans une ouverture correspondante pratiquée dans une patte de support 38 s'étendant au-dessus de la semelle, à l'intérieur du carter 11 du boítier. Cette patte peut être monobloc avec la pièce qui constitue la semelle, avantageusement en matière plastique moulée.The 37A pin is inserted into a corresponding opening made in a support leg 38 extending above the sole, inside the housing 11 of the housing. This leg can be monobloc with the part which constitutes the sole, advantageously in molded plastic.

Du côté opposé, le téton 37B peut être introduit, par exemple par encliquetage, dans la joue 15A formée à l'arrière de la semelle, du côté de la face extérieure de cette joue, ou dans une joue 11A analogue, mais pratiquée dans le carter 11. Ces joues sont par exemple des parois minces en plastique et peuvent être légèrement déformées élastiquement.On the opposite side, the pin 37B can be introduced, for example by snap-fastening, in the cheek 15A formed at the rear of the sole, on the side of the outer face of this cheek, or in a similar 11A cheek, but made in the housing 11. These cheeks are for example walls thin plastic and can be slightly elastically deformed.

La pédale 36 porte une patte de commande 40, dénommée biellette de commande, en raison de sa forme analogue à celle d'une biellette. Toutefois, cette patte est solidaire en rotation de la pédale. Le bâti 34 ou, plus précisément son aile 34A, porte quant à lui une patte commandée 42, dénommée biellette commandée en raison de sa forme, solidaire en rotation du bâti 34 et formant une liaison articulée avec la biellette 40. La biellette commandée 42 peut être réalisée monobloc avec le bâti 34, de même que la biellette de commande 40 peut être monobloc avec la pédale 36. Il peut également s'agir d'éléments rapportés, respectivement solidarisés en rotation avec la pédale et avec le bâti par tout moyen approprié.The pedal 36 carries a control tab 40, called control rod, due to its shape analogous to that of a link. However, this tab is integral in rotation with the pedal. The frame 34 or, more precisely its wing 34A, carries a leg ordered 42, called rod ordered because of its shape, integral in rotation with the frame 34 and forming an articulated connection with the connecting rod 40. The controlled connecting rod 42 can be made in one piece with the frame 34, as well as the control rod 40 may be in one piece with pedal 36. It can also be added components, respectively secured in rotation with the pedal and with the frame by any appropriate means.

Les biellettes 40 et 42 coopèrent entre elles de telle sorte que le pivotement de la pédale 36 autour de son axe D entraíne le pivotement du bâti 34 entre ses positions actives et inactives. A cet effet, l'une des biellettes, par exemple la biellette commandée 40, comporte une lumière 44 dans laquelle est inséré un téton 46 solidaire de l'autre biellette, par exemple la biellette 42. Le bâti 34 tourne autour de l'axe C, qui est par exemple matérialisé par des tétons 35A et 35B, respectivement solidaires des ailes 34A et 34B de ce bâti. Ces tétons ou l'un d'entre eux (en l'espèce, le téton 35A) peuvent être directement solidaires de la ou des biellettes commandées 42, elles(s)-même(s) solidaire(s) des ailes 34A et 34B.The rods 40 and 42 cooperate with each other so that the pivoting of the pedal 36 about its axis D causes the pivoting of the frame 34 between its active and inactive positions. One of the rods, for example the controlled rod 40, includes a light 44 in which is inserted a stud 46 integral with the other link, by example the link 42. The frame 34 rotates around the axis C, which is by example materialized by pins 35A and 35B, respectively integral wings 34A and 34B of this frame. These nipples or one of them (in the species, the nipple 35A) may be directly integral with the one or more controlled rods 42, they (themselves) integral with the wings 34A and 34B.

La figure 3 montre la pédale 36, les biellettes 40 et 42 et le bâti 34 en traits forts dans la position inactive de l'organe racleur arrière 30. Les mêmes éléments sont représentés en traits mixtes interrompus dans la position active dudit organe racleur.Figure 3 shows the pedal 36, the links 40 and 42 and the frame 34 in strong lines in the inactive position of the rear scraper member 30. The same elements are represented in broken lines broken in the active position of said scraper member.

Sur la figure 3, le repère P1 indique le plan de repos du suceur sur le sol lorsque l'organe racleur arrière 30 est dans sa position active. On voit que dans cette situation, le suceur repose sur le sol par les deux organes racleurs 28 et 30, tandis que les roues arrière sont relevées pour être situées à une distance d du sol. On a indiqué par la référence P2 le plan de repos du suceur sur le sol lorsque l'organe racleur 30 occupe sa position inactive, et l'on voit que dans cette situation, le suceur repose par les roues arrière et par l'organe racleur avant 28.In FIG. 3, the reference P1 indicates the plane of rest of the nozzle on the ground when the rear scraper member 30 is in its active position. We sees that in this situation the squeegee rests on the ground by both scraping members 28 and 30, while the rear wheels are raised to be located at a distance d from the ground. We indicated by the reference P2 the rest plane of the squeegee on the ground when the scraper member 30 occupies its inactive position, and we see that in this situation, the squeegee rests by the rear wheels and by the front scraper member 28.

Grâce à la liaison articulée formée par la coopération des biellettes 40 et 42, on commande de manière très simple l'organe racleur 30 entre ses deux positions. Les moyens de commande sont simples, fiables, peu coûteux et peu encombrants. Ceci est notamment dû au fait que seul l'organe racleur arrière 30 doit être commandé par ces moyens de commande, l'organe racleur avant 28 étant fixe.Thanks to the articulated connection formed by the cooperation of the rods 40 and 42, the scraper member 30 is very simply controlled its two positions. The control means are simple, reliable, little expensive and space-saving. This is notably due to the fact that only the rear scraper member 30 must be controlled by these means of control, the front scraper member 28 being fixed.

Comme on le constate en particulier sur la figure 4, on réalise avantageusement ces moyens de commande sur un seul côté du suceur. Ils coopèrent alors avec le bâti 34 seulement par l'aile 34A de ce dernier et portent une unique biellette commandée 42, tandis que la pédale 36 porte une unique biellette de commande 40.As can be seen in particular in FIG. 4, one realizes advantageously these control means on one side of the nozzle. They then cooperate with the frame 34 only by the wing 34A of the latter. and carry a single controlled link 42, while the pedal 36 carries a single control rod 40.

Les deux positions de la pédale 36 représentée sur la figure 3 peuvent être déterminées par des points durs liés à une conformation appropriée des tétons 37A et 37B et des orifices qui les reçoivent. Par ailleurs, la pédale peut coopérer avec des moyens de butée tels que, pour sa position active, l'élément de paroi interne 48 avec lequel coopère la face intérieure de la pédale. The two positions of the pedal 36 shown in Figure 3 can be determined by hard points linked to a conformation appropriate nipples 37A and 37B and the orifices which receive them. Through elsewhere, the pedal can cooperate with stop means such as, for its active position, the internal wall element 48 with which the inside of the pedal.

Plutôt qu'à l'aide d'une pédale du type représenté sur les dessins, on pourrait choisir de commander l'organe racleur arrière à l'aide d'un levier actionnable manuellement, par exemple situé dans une région centrale du carter, au-dessus de l'ouverture d'aspiration.Rather than using a pedal of the type shown in the drawings, one could choose to control the rear scraper member using a manually operable lever, for example located in a region crankcase center, above the suction opening.

Les roues 24, 26 sont disposées de part et d'autre des joues 15A, 15B et l'organe racleur arrière 30 est disposé entre ces joues, le bâti 34 dudit organe racleur comportant les tétons 35A et 35B qui définissent son axe de pivotement C et ces tétons étant encastrés dans ces joues.The wheels 24, 26 are arranged on either side of the cheeks 15A, 15B and the rear scraper member 30 is disposed between these cheeks, the frame 34 of said scraper member comprising pins 35A and 35B which define its pivot axis C and these nipples being embedded in these cheeks.

Les tétons 35A, 35B coopèrent avec les joues 15A, 15B par encliquetage.The nipples 35A, 35B cooperate with the cheeks 15A, 15B by snap-in.
