Description

SUCEUR D'ASPIRATEUR VACUUM CLEANER
La présente invention concerne un suceur d'aspirateur comprenant un boîtier susceptible d'être raccordé, vers le haut et vers l'arrière, à un tube d'aspiration par l'intermédiaire d'un manchon de raccordement pivotant, une semelle qui est située sous le boîtier et qui présente un canal d'aspiration dont le fond s'étend en creux dans la semelle, une ouverture d'aspiration située dans le canal d'aspiration, un organe racleur situé sous le boîtier et des roues arrière, l'axe de pivotement du manchon de raccordement 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 housing capable of being connected, upwards and backwards, to a suction tube by means of a pivoting connection sleeve, a soleplate which is located under the housing and which has a suction channel, the bottom of which recesses in the sole, a suction opening located in the suction channel, a scraper member located under the housing and rear wheels, the pivot axis of the connecting sleeve being located behind the axis of rotation of said wheels or coinciding with this axis of rotation.
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 tel qu'une raclette qui, lors du passage du suceur sur le sol, frotte sur le sol pour favoriser le nettoyage. On connaît des suceurs de ce type, pour lesquels l'organe racleur, constitué par une ou plusieurs brosses, est monté sur une platine logée dans le boîtier. Les fabriquants de suceurs d'aspirateur considèrent en général que l'organe racleur doit pouvoir être escamoté dans le boîtier pour le passage du suceur sur des tapis ou des moquettes, tandis qu'il doit faire saillie sous la semelle à travers une fente de cette dernière pour le passage du suceur sur les sols durs. Ainsi, la plupart des suceurs connus comportent un dispositif de commande permettant d'escamoter l'organe racleur, qui comprend une platine actionnée par une pédale. La nécessité de prévoir de tels moyens de commande augmente considérablement les coûts de fabrication du suceur et, du fait de la nécessité de les actionner fréquemment, ces moyens risquent de s'user ou de se détériorer.The term “scraper member” is intended to denote any member such as a brush, for example of the type commonly referred to as "strips" by those skilled in the art, or such as a squeegee which, when the nozzle is passed over the ground, rubs on the floor to promote cleaning. Nozzles of this type are known, for which the scraper member, consisting of one or more brushes, is mounted on a plate housed in the housing. Manufacturers of vacuum cleaner nozzle generally consider that the scraper member must be able to be retracted into the housing for the passage of the nozzle on carpets or rugs, while it must protrude under the soleplate through a slot in this last for the passage of the squeegee on hard floors. Thus, most of the known nozzles have a control device making it possible to retract the scraper member, which comprises a plate actuated by a pedal. The need to provide such control means considerably increases the manufacturing costs of the nozzle and, because of the need to actuate them frequently, these means risk wearing out or deteriorating.
La demande de brevet français 2 729 842, au nom de la demanderesse, simplifie ces suceurs connus en prévoyant la possibilité d'escamoter automatiquement l'organe racleur selon que le suceur est poussé ou tiré. Ainsi, la semelle présente un logement longitudinal en creux qui permet à l'organe racleur de venir se replier en position escamotée, ce logement étant délimité par un élément de paroi contre lequel l'organe racleur coopère en butée dans sa position active. II est vrai que ces dispositions permettent de limiter les coûts de fabrication du suceur ainsi que ses risques d'usure, puisqu'aucun dispositif d'actionnement particulier ne doit être prévu. Cependant, la nécessité de prévoir l'élément de paroi et le logement pour l'organe racleur en position escamotée oblige à adapter la dimension antéro-postérieure de la semelle en conséquence. De plus, l'organe racleur ne travaille efficacement que lorsqu'il occupe sa position active, c'est-à-dire seulement lorsque le suceur est déplacé sur le sol dans le sens de la traction.French patent application 2,729,842, in the name of the applicant, simplifies these known nozzles by providing for the possibility of automatically retracting the scraper member as the nozzle is pushed or pulled. Thus, the sole has a recessed longitudinal housing which allows the scraper member to come back to the retracted position, this housing being delimited by a wall element against which the scraper member cooperates in abutment in its active position. It is true that these provisions make it possible to limit the costs of manufacturing the nozzle and its risks of wear, since no no special actuation device should be provided. However, the need to provide the wall element and the housing for the scraper member in the retracted position means that the anteroposterior dimension of the sole has to be adapted accordingly. In addition, the scraper member works effectively only when it occupies its active position, that is to say only when the nozzle is moved over the ground in the direction of traction.
On a longtemps pensé qu'il n'est pas possible d'équiper un suceur destiné à être utilisé sur tous types de sols d'un organe racleur fixe, et que l'organe racleur devait être obligatoirement escamoté lors du passage du suceur sur des sols tels que des tapis ou des moquettes, pour éviter à l'utilisateur ou à l'utilisatrice un effort trop important. C'est lors du déplacement de poussée du suceur sur le sol que l'utilisateur ou l'utilisatrice exerce l'effort maximal, tandis que le mouvement de traction vers l'arrière est moins pénible. Ainsi, dans la demande de brevet français 2 729 842 précitée, il était prévu que l'organe racleur n'occupe sa position active que lors des mouvements de traction vers l'arrière ce qui, comme indiqué précédemment, présente l'inconvénient de ne rendre l'organe racleur efficace que sur la moitié du trajet du suceur sur le sol. L'invention a pour but de proposer un suceur encore plus simple et moins coûteux à fabriquer que les suceurs de l'art antérieur précité, qui soit utilisable sur tous types de sols, sans effort démesuré de la part de l'utilisateur ou l'utilisatrice, tout en donnant des résultats, quant à la qualité de l'aspiration et au nettoyage final des sols, qui soient au moins comparables à ceux des suceurs de l'art antérieur, voire meilleurs.It has long been thought that it is not possible to equip a squeegee intended for use on all types of soil with a fixed scraper member, and that the scraper member must be retracted when passing the squeegee over floors such as rugs or carpets, to save the user too much effort. It is during the pushing movement of the squeegee on the ground that the user exerts the maximum effort, while the pulling movement towards the rear is less painful. Thus, in the aforementioned French patent application 2 729 842, it was provided that the scraper member occupies its active position only during rearward traction movements which, as indicated above, has the drawback of not make the scraper organ effective only on half of the path of the squeegee on the ground. The object of the invention is to propose a nozzle which is even simpler and less expensive to manufacture than the nozzle of the aforementioned prior art, which can be used on all types of soil, without excessive effort on the part of the user or the user, while giving results, as to the quality of the suction and the final cleaning of the floors, which are at least comparable to those of the nozzles of the prior art, or even better.
Ce but est atteint grâce au fait que l'organe racleur est fixe et fait continuellement saillie sous la semelle, le plan de repos du suceur sur le sol étant défini par les zones de contact des roues arrière et de l'organe racleur avec le sol et l'ensemble de la semelle étant continuellement situé en retrait par rapport à ce plan de repos, et au fait que l'organe racleur s'étend seulement dans une zone longitudinale du suceur qui, considérée par rapport au bord arrière de l'ouverture d'aspiration, se trouve à l'avant du suceur.This object is achieved thanks to the fact that the scraper member is fixed and continuously protrudes under the sole, the rest plane of the squeegee on the ground being defined by the zones of contact of the rear wheels and of the scraper member with the ground. and the entire sole being continuously set back relative to this rest plane, and to the fact that the scraper member extends only in a longitudinal zone of the nozzle which, considered with respect to the rear edge of the opening is located at the front of the squeegee.
La présente invention, en prévoyant un organe racleur qui fasse continuellement saillie sous la semelle, permet de faire en sorte qu'il soit continûment actif et efficace. A la suite de nombreux essais, on s'est aperçu que le fait de prévoir un organe racleur fixe, dans la mesure où celui-ci équipe un suceur dit "à corps flottant" (c'est-à-dire un suceur dans lequel l'axe de pivotement du manchon de raccordement est situé en arrière de l'axe de rotation des roues arrière ou est tout au plus confondu avec ce dernier), et dans la mesure où ledit organe racleur est situé dans une zone du suceur qui s'étend en avant du bord arrière de l'ouverture d'aspiration, donne d'excellents résultats en matière de qualité d'aspiration et n'oblige pas l'utilisateur ou l'utilisatrice à accomplir des efforts importants pour déplacer le suceur sur le sol, que celui-ci soit constitué par un tapis ou une moquette ou par un sol dur.The present invention, by providing a scraper member which projects continuously under the sole, makes it possible to ensure that it is continuously active and effective. Following numerous tests, it has been found that the fact of providing a fixed scraper member, insofar as this equips a so-called "floating body" nozzle (that is to say a nozzle in which the pivot axis of the connecting sleeve is located behind the axis of rotation of the rear wheels or is at most coincident with the latter), and insofar as said scraper member is located in a zone of the nozzle which s extends in front of the rear edge of the suction opening, gives excellent results in terms of suction quality and does not force the user to make significant efforts to move the squeegee on the floor, whether it is a carpet or carpeted floor or hard floor.
En effet, dans un suceur à corps flottant, l'effort appliqué par l'utilisateur ou l'utilisatrice sert simplement à faire rouler les roues arrière et à permettre le déplacement du suceur, sans plaquer ce dernier contre le sol, c'est seulement sous l'effet de la dépression engendrée par l'aspiration que le suceur à corps flottant est plaqué contre le sol. Le fait d'utiliser un organe racleur fixe permet de s'affranchir de la nécessité de prévoir des moyens de commande du déplacement de l'organe racleur, ou même des moyens de sollicitation automatique de l'organe racleur vers sa position active ou vers sa position inactive. Quel que soit le sens de déplacement du suceur sur le sol, l'organe racleur occupe la même position et son efficacité est constamment assurée.Indeed, in a floating body nozzle, the force applied by the user simply serves to roll the rear wheels and allow the displacement of the nozzle, without pressing the latter against the ground, it is only under the effect of the depression generated by the aspiration that the floating body nozzle is pressed against the ground. The fact of using a fixed scraper member eliminates the need to provide means for controlling the movement of the scraper member, or even means for automatically urging the scraper member towards its active position or towards its inactive position. Whatever the direction of movement of the squeegee on the ground, the scraper member occupies the same position and its efficiency is constantly ensured.
Le fait de prévoir que l'organe racleur s'étende dans une région avant du suceur par rapport au bord arrière de l'ouverture d'aspiration permet de conférer au suceur son efficacité maximum. En effet, d'une part, l'organe racleur est suffisamment éloigné des roues arrière pour qu'effectivement aucun effort vertical ne soit directement exercé sur cet organe racleur lorsque l'utilisateur ou l'utilisatrice exerce un effort sur les roues arrière pour déplacer le suceur sur le sol. De plus, grâce à cette disposition, le suceur est parfaitement stabilisé sur le sol puisqu'il repose, dans sa région arrière, sur les roues arrière et, dans sa région avant, sur l'extrémité inférieure de l'organe racleur. L'efficacité de l'aspiration est tout à fait satisfaisante dans la mesure où, lors de la poussée du suceur, les poussières détachées du sol par l'organe racleur sont ensuite aspirées dans l'ouverture d'aspiration. On obtient ainsi un bon compromis entre les efforts de poussée à exercer pour déplacer le suceur sur le sol et l'enlèvement de la poussière. Pour diminuer les efforts de poussée nécessaires tout en conservant les mêmes résultats en termes d'enlèvement de poussière, on choisit avantageusement de placer l'axe de pivotement du manchon plus proche du sol que dans les suceurs à corps flottant traditionnels, par exemple en diminuant le rayon des roues arrière.Providing that the scraper member extends in a region before the nozzle relative to the rear edge of the suction opening allows to give the nozzle maximum efficiency. Indeed, on the one hand, the scraper member is sufficiently distant from the rear wheels so that effectively no vertical force is directly exerted on this scraper member when the user exerts a force on the rear wheels to move the nozzle on the floor. In addition, thanks to this arrangement, the nozzle is perfectly stabilized on the ground since it rests, in its rear region, on the rear wheels and, in its front region, on the lower end of the scraper member. The suction efficiency is entirely satisfactory insofar as, when the squeegee is pushed, the dust detached from the ground by the scraper member is then sucked into the suction opening. A good compromise is thus obtained between the thrust forces to be exerted to move the nozzle on the ground and dust removal. To reduce the necessary thrust forces while retaining the same results in terms of dust removal, it is advantageous to choose to place the pivot axis of the sleeve closer to the ground than in traditional floating body squeegees, for example by reducing the radius of the rear wheels.
Selon une disposition avantageuse, l'organe racleur est disposé dans le canal d'aspiration et, sur une partie au moins de la longueur dudit canal, sépare ce dernier en une portion de canal avant et une portion de canal arrière.According to an advantageous arrangement, the scraper member is disposed in the suction channel and, over at least part of the length of said channel, separates the latter into a front channel portion and a rear channel portion.
Grâce à cette disposition, les poussières repoussées vers l'avant par l'organe racleur lors de la poussée du suceur, et les poussières repoussées vers l'arrière lors de la traction sur le suceur sont parfaitement aspirées. De plus, l'organe racleur est "autonettoyant", puisque la dépression créée par l'aspiration s'exerce dans le canal d'aspiration, c'est- à-dire dans la région dans laquelle l'organe racleur est disposé, et nettoie ce dernier.Thanks to this arrangement, the dust repelled towards the front by the scraper member when the squeegee is pushed, and the dust repelled towards the rear during the pulling on the squeegee are perfectly sucked. In addition, the scraper member is "self-cleaning", since the vacuum created by the suction is exerted in the suction channel, that is to say in the region in which the scraper member is disposed, and cleans it.
Des tests ont été réalisés conformément à la norme CEI 60312, sur le tapis dit "tapis Wilton" auquel cette norme fait référence. Ces tests ont consisté à mesurer la capacité d'aspiration sur ce tapis d'un aspirateur équipé, d'abord, d'un suceur ne comportant pas d'organe racleur et, ensuite, d'un suceur du même type, mais avec un organe racleur disposé dans le canal d'.^spiration selon la disposition précitée. On a constaté que l'efficacité, en termes de dépoussiérage du tapis, était supérieure d'environ 10 % avec le deuxième suceur par rapport au premier.Tests have been carried out in accordance with standard IEC 60312, on the so-called "Wilton carpet" to which this standard refers. These tests consisted in measuring the suction capacity on this conveyor belt of a vacuum cleaner equipped, first, with a squeegee not comprising a scraper member and, then, with a squeegee of the same type, but with a scraper member disposed in the spiral channel according to the above-mentioned arrangement. It was found that the efficiency, in terms of dusting the carpet, was about 10% higher with the second nozzle compared to the first.
Avantageusement, le suceur comporte des éléments de paroi qui ferment sensiblement la portion de canal arrière sur les côtés de la semelle.Advantageously, the nozzle has wall elements which substantially close the rear channel portion on the sides of the sole.
Cette disposition permet d'augmenter la dépression dans la portion de canal arrière, ce qui plaque davantage le suceur sur le sol et confine les poussières dans la portion de canal arrière, avant de les aspirer dans l'ouverture d'aspiration, sans pour autant trop augmenter les efforts que doit exercer l'utilisateur ou l'utilisatrice déplaçant le suceur sur le sol.This arrangement increases the vacuum in the rear channel portion, which further presses the squeegee on the ground and confines the dust in the rear channel portion, before sucking them into the suction opening, without however Too much increase the efforts that the user must exert moving the nozzle on the floor.

- la figure 1 montre, en perspective et en vue de dessous, un suceur conforme à l'invention, - la figure 2 montre le suceur de la figure 1 en coupe dans un plan antéro-postérieur selon la ligne ll-ll de la figure 3, et- Figure 1 shows, in perspective and in bottom view, a nozzle according to the invention, - Figure 2 shows the nozzle of Figure 1 in section in an anteroposterior plane along the line ll-ll of the figure 3, and
- la figure 3 montre le même suceur en coupe longitudinale dans le plan lll-lll de la figure 2.FIG. 3 shows the same nozzle in longitudinal section in the plane III-III of FIG. 2.
Les figures montrent un suceur d'aspirateur comprenant un boîtier 10, susceptible à l'aide d'un manchon de raccordement 12 dirigé vers le haut et vers l'arrière, d'être raccordé à un tube d'aspiration (non représenté). Le suceur comporte également une semelle 14 située sous le boîtier et munie d'une ouverture d'aspiration 16.The figures show a vacuum cleaner nozzle comprising a housing 10, capable of being connected to a suction tube (not shown) by means of a connection sleeve 12 directed upwards and rearwards. The squeegee also includes a soleplate 14 located under the housing and provided with a suction opening 16.
Dans toute la suite, on considérera que les parties avant des divers éléments qui seront décrits seront celles qui sont les plus éloignées de l'ouverture 12A du manchon 12 à laquelle on raccorde le tube d'aspiration. Ainsi, le sens vers l'avant (indiqué par la flèche F sur la figure 2) correspond naturellement au sens de poussée du suceur dans les conditions d'utilisation normale de ce dernier, tandis que le sens vers l'arrière (indiqué par la flèche G) correspond au sens vers lequel on tire le suceur. De plus, on considérera que la direction longitudinale du suceur, indiquée par la double flèche L sur la figure 3, est perpendiculaire à la direction antéro-postérieure de ce suceur, indiqué par la double flèche A-P sur la figure 2. L'ouverture d'aspiration 16 est réalisée dans la partie centrale d'un canal d'aspiration 18 ménagé en creux dans la semelle. La face inférieure de la semelle comporte une première et une deuxième bandes arrache-fils 20, 22 respectivement ménagées en avant et en arrière de l'ouverture de l'aspiration 16. Comme l'indique la double flèche P de la figure 2, le manchon de raccordement 12 est monté pivotant par rapport au boîtier 10. Il pivote autour d'un axe de pivotement qui, dans l'exemple représenté, est sensiblement confondu avec l'axe de rotation A de roues arrière 24 et 26. De manière générale, l'axe de pivotement du manchon de raccordement coïncide avec l'axe de rotation A ou est situé en arrière de ce dernier, de sorte que le suceur est du type "à corps flottant". Le suceur comporte également un organe racleur 28 qui fait saillie sous la semelle 14, l'extrémité inférieure 28A de l'organe racleur s'étendant sur une distance H vers le bas au-delà des parties de la semelle les plus basses lorsque le suceur repose sur le sol. Avantageusement, ces parties les plus basses sont respectivement disposées sur les bords avant et arrière du canal d'aspiration, respectivement 18A et 18B. La distance H est avantageusement comprise entre 1 et 4mm, de préférence de l'ordre de 3mm. L'organe racleur 28 est fixe et non escamotable, de sorte que le plan de repos PR du suceur sur le sol est défini par les zones de contact des roues arrière 24 et 26 avec le sol et par l'extrémité inférieure 28A de l'organe racleur, également en contact avec le sol. Comme on le voit sur la figure 2, l'ensemble de la semelle est située en retrait par rapport à ce plan PR, c'est-à-dire qu'il se trouve au-dessus du sol et sans contact avec ce dernier lorsque le suceur repose sur le sol. Pour faciliter la visualisation sur la figure 3, on a légèrement relevé la partie avant du suceur, l'extrémité inférieure 28A de l'organe racleur 28 se trouvant ainsi légèrement au-dessus du plan de contact des roues arrière avec le sol.In what follows, it will be considered that the front parts of the various elements which will be described will be those which are the furthest from the opening 12A of the sleeve 12 to which the suction tube is connected. Thus, the direction towards the front (indicated by the arrow F in FIG. 2) naturally corresponds to the direction of thrust of the squeegee under the conditions of normal use of the latter, while the direction towards the rear (indicated by the arrow G) corresponds to the direction in which the nozzle is drawn. In addition, it will be considered that the longitudinal direction of the nozzle, indicated by the double arrow L in FIG. 3, is perpendicular to the anteroposterior direction of this nozzle, indicated by the double arrow AP in FIG. 2. The opening of 'suction 16 is carried out in the central part of a suction channel 18 formed hollow in the sole. The underside of the sole has first and second wire-stripping strips 20, 22 respectively formed in front of and behind the opening of the suction 16. As indicated by the double arrow P in FIG. 2, the connection sleeve 12 is pivotally mounted relative to the housing 10. It pivots about a pivot axis which, in the example shown, is substantially coincident with the axis of rotation A of rear wheels 24 and 26. In general , the pivot axis of the connecting sleeve coincides with the axis of rotation A or is situated behind the latter, so that the nozzle is of the "floating body" type. The squeegee also comprises a scraper member 28 which projects under the sole 14, the lower end 28A of the scraper member extending a distance H downward beyond the lowest parts of the sole when the squeegee rests on the ground. Advantageously, these lowest parts are respectively arranged on the front and rear edges of the suction channel, respectively 18A and 18B. The distance H is advantageously between 1 and 4mm, preferably of the order of 3mm. The scraper member 28 is fixed and not retractable, so that the rest plane PR of the squeegee on the ground is defined by the contact zones of the rear wheels 24 and 26 with the ground and by the lower end 28A of the scraper member, also in contact with the ground. As seen in Figure 2, the entire sole is set back from this plane PR, that is to say that it is above the ground and without contact with the latter when the squeegee rests on the ground. To facilitate viewing in FIG. 3, the front part of the nozzle is slightly raised, the lower end 28A of the scraper member 28 thus being slightly above the plane of contact of the rear wheels with the ground.
Comme on le voit en particulier sur les figures 1 et 2, l'organe racleur 28 s'étend seulement dans une zone longitudinale du suceur qui, considéré par rapport au bord arrière 16A de l'ouverture d'aspiration, se trouve à l'avant du suceur.As can be seen in particular in FIGS. 1 and 2, the scraper member 28 extends only in a longitudinal zone of the squeegee which, considered with respect to the rear edge 16A of the suction opening, is located at the before the squeegee.
L'organe racleur 28 est disposé dans le canal d'aspiration 18. Plus précisément, il comporte deux tronçons 29A et 29B alignés dans le sens longitudinal du suceur et disposés de part et d'autre de l'ouverture d'aspiration 16. Dans l'exemple représenté, l'organe racleur est donc interrompu dans la région de l'ouverture d'aspiration, mais on pourrait également utiliser un organe racleur continu s'étendant en travers de l'ouverture d'aspiration. On voit sur les figures 1 et 2 que, en avant et en arrière de chacun des tronçons 29A et 29B, le canal d'aspiration 18 est ainsi séparé en une portion de canal avant 18C et une portion de canal arrière 18D. L'organe racleur 28 (plus précisément ses tronçons 29A et 29B) est disposé sensiblement au milieu de la largeur du canal 18 mesurée dans la direction antéro-postérieure du suceur. Des éléments de parois, respectivement 19A et 19B ferment sensiblement la portion de canal arrière 18D sur les côtés de la semelle. Plus précisément, comme on le voit sur la figure 2, ces éléments de parois s'étendent vers le bas lorsque le suceur est posé sur le sol sensiblement jusqu'au même niveau que les bords avant et arrière 18A et 18B du canal d'aspiration 18. Ils s'étendent sur toute la largeur de la portion de canal arrière 18D mesurée dans la direction antéro-postérieure du suceur, sensiblement jusqu'à la face avant de l'organe racleur 28.The scraper member 28 is disposed in the suction channel 18. More specifically, it comprises two sections 29A and 29B aligned in the longitudinal direction of the nozzle and arranged on either side of the suction opening 16. In the example shown, the scraper member is therefore interrupted in the region of the suction opening, but one could also use a continuous scraper member extending across the suction opening. It can be seen in FIGS. 1 and 2 that, in front and behind each of the sections 29A and 29B, the suction channel 18 is thus separated into a front channel portion 18C and a rear channel portion 18D. The scraper member 28 (more precisely its sections 29A and 29B) is disposed substantially in the middle of the width of the channel 18 measured in the anteroposterior direction of the nozzle. Wall elements, respectively 19A and 19B substantially close the rear channel portion 18D on the sides of the sole. More precisely, as can be seen in FIG. 2, these wall elements extend downwards when the nozzle is placed on the ground substantially up to the same level as the front and rear edges 18A and 18B of the suction channel 18. They extend over the entire width of the rear channel portion 18D measured in the anteroposterior direction of the squeegee, substantially up to the front face of the scraper member 28.
L'organe racleur 28 peut être constitué par une brosse ou "strips" connue en soi. Plus précisément, dans l'exemple représenté, il comporte deux tronçons d'une telle brosse. Compte tenu de la nature des poils utilisés et de leur densité, cette brosse est suffisamment rigide pour ne pas se plier et "beurrer" le sol lors du déplacement du suceur sur le sol.The scraper member 28 may consist of a brush or "strips" known per se. More specifically, in the example shown, it comprises two sections of such a brush. Given the nature of the bristles used and their density, this brush is rigid enough not to bend and "butter" the floor when the nozzle is moved over the floor.
En variante, l'organe racleur peut être formé par une bande en matière plastique, également convenablement choisie pour ne pas se plier sur elle-même lors du déplacement du suceur. Si nécessaire, on peut choisir de doter l'organe racleur de fentes transversales afin de créer de petits passages d'aspiration pour les poussières, ce qui sera particulièrement avantageux si, selon une variante non représentée, l'organe racleur se trouve à l'avant du canal d'aspiration 18. Les deux tronçons 29A et 29B de l'organe racleur peuvent être disposés de manière à former les branches d'un V très ouvert, dont la pointe, interrompue dans la région de l'ouverture d'aspiration, serait tournée vers l'arrière du suceur.As a variant, the scraper member can be formed by a plastic strip, also suitably chosen so as not to fold on itself when the nozzle is moved. If necessary, it is possible to choose to provide the scraper member with transverse slots in order to create small suction passages for dust, which will be particularly advantageous if, according to a variant not shown, the scraper member is located front of the suction channel 18. The two sections 29A and 29B of the scraper member can be arranged so as to form the branches of a very open V, the tip of which is interrupted in the region of the suction opening , would face the rear of the squeegee.
La semelle du suceur d'aspirateur conforme à l'invention présente une géométrie simple et, comme on le comprend sur la figure 2, peut éventuellement être moulée en une seule pièce avec la paroi supérieure 30 du boîtier (dont la face inférieure délimite l'ouverture d'aspiration et le guide du pivotement de la pièce 32 qui porte le manchon 12). Eventuellement, un simple carter de décoration 34 indiqué en traits interrompus mixtes sur la figure 2 peut être ajouté pour parfaire l'esthétique du suceur. Les axes 24A et 26A de rotation des roues peuvent également être réalisés en une seule pièce avec la semelle, les roues pouvant quant à elles être emmanchées à force sur ces axes.The soleplate of the vacuum cleaner nozzle according to the invention has a simple geometry and, as can be understood in FIG. 2, can optionally be molded in one piece with the upper wall 30 of the housing (the lower face of which delimits the suction opening and the guide for pivoting the part 32 which carries the sleeve 12). Optionally, a simple decorative casing 34 indicated in broken dashed lines in FIG. 2 can be added to perfect the appearance of the nozzle. The axes 24A and 26A of rotation of the wheels can also be made in one piece with the sole, the wheels being able to be force fitted on these axes.
Cette possibilité de réaliser en une seule pièce la semelle et la paroi 30 est liée au fait que, l'organe racleur étant fixe, le boîtier est exempt de moyens de commande d'escamotage de cet organe racleur. Par exemple, l'organe racleur peut être monté sur une simple monture profilée encliquetée ou emmanchée à force dans une ouverture longitudinale correspondante que présente la face inférieure de la semelle. En prolongeant l'ouverture d'aspiration, on peut disposer un deuxième canal d'aspiration en creux (non représenté), situé en arrière du canal 18, les deux canaux étant séparés par une paroi longitudinale.This possibility of producing the soleplate and the wall 30 in one piece is linked to the fact that, the scraper member being fixed, the housing is free of means for controlling the retraction of this scraper member. For example, the scraper member can be mounted on a simple profiled mount snapped or force fitted into a corresponding longitudinal opening that has the underside of the sole. By extending the suction opening, a second hollow suction channel (not shown) can be arranged, located behind the channel 18, the two channels being separated by a longitudinal wall.
On peut également disposer un organe racleur secondaire 36 représenté en traits interrompus sur la figure 2 et situé en arrière de l'organe 28, par exemple dans la région de la rainure 38 située vers l'arrière de la semelle. Pour éviter de soulever la semelle et d'augmenter les efforts de poussée nécessaires pour déplacer le suceur sur le sol, cet organe racleur secondaire est de préférence doté d'une grande flexibilité et/ou est disposé de telle sorte que son extrémité libre s'étend en retrait par rapport au plan PR (jeu j). L'organe racleur secondaire est par exemple une raclette en matière plastique très flexible. One can also have a secondary scraper member 36 shown in broken lines in Figure 2 and located behind the member 28, for example in the region of the groove 38 located towards the rear of the sole. To avoid lifting the sole and increasing the thrust forces necessary to move the squeegee on the ground, this secondary scraper member is preferably provided with great flexibility and / or is arranged so that its free end s' extends back from the PR plane (clearance j). The secondary scraper member is for example a very flexible plastic squeegee.
