Definitions
- the present invention relates to a vacuum cleaner nozzle comprising a box capable of being connected, upwards and backwards, to a suction tube via a connection sleeve swivel, a sole 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 sleeve of connection being located behind the axis of rotation of said wheels or coinciding with this axis of rotation.
- swipe member is intended to denote any member such as a brush, for example of the type commonly referred to as “strips” by a person skilled in the art, or such as a squeegee which, during the passage of the nozzle on the floor, rub on the floor to promote cleaning.
- suckers of this type for which the scraper member, consisting of one or more brushes, is mounted on a plate housed in the case.
- the manufacturers of vacuum cleaner nozzles consider general that the scraper member must be able to be retracted into the housing for the passage of the squeegee on carpets or rugs, while it must protrude under the sole through a slit in the latter for the passage of the squeegee on hard floors.
- most of the suckers known include a control device for retracting the scraper member, which comprises a plate actuated by a pedal. The need to provide such control means increases considerably the manufacturing costs of the squeegee and, due to the need to operate them frequently, these means may wear out or deteriorate.
- French patent application FR-A-2 729 842 simplifies these known suckers by providing for the possibility automatically retract the scraper member depending on whether the squeegee is pushed or pulled.
- the sole has a longitudinal housing in hollow which allows the scraper member to fold back into position retracted, this housing being delimited by a wall element against which the scraper member cooperates in abutment in its active position.
- Document JP-A-05261038 discloses a vacuum cleaner nozzle, the sole has two wire-stripping elements located in its part front and sides, as well as two brushes, respectively arranged in front and behind the suction opening. At the back, the squeegee has a wire puller roller. The scraping organs that constitute brushes are fixed, which is allowed by the fact that these brushes are in shrinkage with respect to the fixed wire stripping elements and the roller hard son.
- the object of the invention is to propose an even simpler nozzle and less expensive to manufacture than the nozzles of the aforementioned prior art, which can be used on all types of soil, without excessive effort on the part of the user, while giving results, as to the quality suction and final cleaning of floors, which are at least comparable to those of the nozzles of the prior art, or even better.
- the present invention by providing a scraper member which makes continuously protruding under the sole, helps to ensure that it is continuously active and effective.
- the scraper member extends into a region front of the squeegee relative to the rear edge of the suction opening helps to give the nozzle maximum efficiency. Indeed, from apart, the scraper member is far enough away from the rear wheels to that indeed 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 ground. In addition, thanks to this available, the squeegee 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 scraper member is arranged in the suction channel and over at least part of the length of the said channel channel, separates the latter into a portion of front channel and a portion of rear channel.
- the scraper member is "self-cleaning", since the depression created by aspiration is exerted in the suction channel, that is to say in the region in which the scraper member is placed, and cleans this last.
- the nozzle has wall elements which substantially close the rear channel portion on the sides of the sole.
- This arrangement increases the depression in the portion rear channel, which further pushes the squeegee to the ground and confines the dust in the rear channel portion, before sucking it in the suction opening, without increasing the efforts too much must exercise the user moving the nozzle on the floor.
- the figures show a vacuum cleaner nozzle including a housing 10, susceptible by means of a connection sleeve 12 directed towards the top and back, to be connected to a suction tube (not represented).
- the squeegee also has a sole 14 located under the housing and provided with a suction opening 16.
- connection sleeve 12 is pivotally mounted by 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 rear wheels 24 and 26. In general, the pivot axis of the connection sleeve coincides with or is located on the axis of rotation A behind the latter, so that the nozzle is of the "body type floating".
- the squeegee also includes a scraper member 28 which projects under the sole 14, the lower end 28A of the scraper member extending a distance H downward beyond parts of the lowest sole when the squeegee rests on the ground.
- these lowest parts are respectively arranged on the front and rear edges of the suction channel, 18A and 18B respectively.
- the distance H is advantageously included between 1 and 4mm, preferably around 3mm.
- the scraper member 28 is fixed and not retractable, so that the plane of rest 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.
- the organ scraper 28 extends only in a longitudinal zone of the nozzle which, considered relative to the rear edge 16A of the suction opening, is located at the front of the squeegee.
- the scraper member 28 is disposed in the suction channel 18. More specifically, it has two sections 29A and 29B aligned in the direction longitudinal of the squeegee and arranged on either side of the opening suction 16. In the example shown, the scraper member is therefore interrupted in the area of the suction opening but we could also use a continuous scraper member extending across the suction opening.
- the suction channel 18 is thus separated into a channel portion before 18C and a channel portion rear 18D.
- the scraper member 28 (more precisely its sections 29A and 29B) is arranged substantially in the middle of the width of the channel 18 measured in the anteroposterior direction of the squeegee.
- Wall elements respectively 19A and 19B close substantially the rear channel portion 18D on the sides of the sole. More precisely, as can be seen in FIG. 2, these elements of walls extend downwards when the nozzle is placed on the floor substantially 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 from the squeegee, substantially to the front face of the scraper member 28.
- 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 hairs used and their density, this brush is rigid enough not to not bend and "butter" the floor when moving the squeegee on the floor.
- the scraper member may be formed by a strip of plastic material, also suitably chosen not to bend on itself when moving the squeegee.
- the scraper member can choose to provide the scraper member with slots transverse to create small suction passages for dust, which will be particularly advantageous if, according to a variant not shown, the scraper member is located at the 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, interrupted in the region of the suction opening, would facing the rear of the squeegee.
- the sole of the vacuum cleaner nozzle according to the invention has simple geometry and, as can be understood in Figure 2, can optionally be molded in one piece with the top wall 30 of the housing (the underside of which delimits the suction opening and the guide for pivoting the part 32 which carries the sleeve 12).
- a simple decoration housing 34 indicated in lines interrupted mixed in Figure 2 can be added to perfect the aesthetics of the squeegee.
- the axes 24A and 26A of rotation of the wheels can also be made in one piece with the sole, the wheels can be force fitted on these axes.
- the scraper member can be mounted on a simple mount profile snapped or force fitted into an opening corresponding longitudinal that the underside of the sole.
- a second hollow suction channel (not shown), located behind the channel 18, the two channels being separated by a longitudinal wall.
- the secondary scraper member is preferably endowed with great flexibility and / or is arranged so that its free end recedes compared to the PR plan (set j).
- the secondary scraper member is by example a very flexible plastic squeegee.
Description
La présente invention concerne un suceur d'aspirateur comprenant un boítier 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 boítier 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 boítier 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 box capable of being connected, upwards and backwards, to a suction tube via a connection sleeve swivel, a sole 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 sleeve of connection 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.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 a person skilled in the art, or such as a squeegee which, during the passage of the nozzle on the floor, rub on the floor to promote cleaning.
On connaít des suceurs de ce type, pour lesquels l'organe racleur, constitué par une ou plusieurs brosses, est monté sur une platine logée dans le boítier. Les fabriquants de suceurs d'aspirateur considèrent en général que l'organe racleur doit pouvoir être escamoté dans le boítier 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.We know suckers of this type, for which the scraper member, consisting of one or more brushes, is mounted on a plate housed in the case. The manufacturers of vacuum cleaner nozzles consider general that the scraper member must be able to be retracted into the housing for the passage of the squeegee on carpets or rugs, while it must protrude under the sole through a slit in the latter for the passage of the squeegee on hard floors. So most of the suckers known include a control device for retracting the scraper member, which comprises a plate actuated by a pedal. The need to provide such control means increases considerably the manufacturing costs of the squeegee and, due to the need to operate them frequently, these means may wear out or deteriorate.
La demande de brevet français FR-A-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.French patent application FR-A-2 729 842, in the name of Applicant, simplifies these known suckers by providing for the possibility automatically retract the scraper member depending on whether the squeegee is pushed or pulled. Thus, the sole has a longitudinal housing in hollow which allows the scraper member to fold back into position retracted, this housing being delimited by a wall element against which the scraper member cooperates in abutment in its active position.
Il 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.It is true that these provisions make it possible to limit the costs of manufacture of the squeegee and its risk of wear, since none no special actuation device should be provided. However, the need to provide the wall element and the housing for the organ scraper in retracted position requires adaptation of the dimension anteroposterior of the sole accordingly. In addition, the organ scraper only works effectively when it is in its active position, that is to say only when the nozzle is moved on the ground in the sense 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'utiltsateur 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 FR-A-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.It has long been thought that it is not possible to equip a nozzle intended to be used on all types of soil with a fixed scraper member, and the scraper member must be retracted when passing the crevice on floors such as carpets or rugs, to avoid the user too much effort. It is during displacement of the squeegee thrust on the ground that the user or the user exerts the maximum effort, while the pulling movement backwards is less painful. Thus, in the French patent application FR-A-2 729 842 above, it was intended that the scraper member does not occupy its position active only when pulling backwards which, like indicated above, has the drawback of not rendering the organ effective scraper only on half the path of the squeegee on the ground.
Le document JP-A-05261038 divulgue un suceur d'aspirateur dont la semelle comporte deux éléments arrache-fils situés dans sa partie avant et sur les côtés, ainsi que deux brosses, respectivement disposées en avant et en arrière de l'ouverture d'aspiration. A l'arrière, le suceur comporte un rouleau arrache-fils. Les organes racleurs que constituent les brosses sont fixes, ce qui est autorisé par le fait que ces brosses sont en retrait par rapport aux éléments arrache-fils fixes et au rouleau arrache-fils.Document JP-A-05261038 discloses a vacuum cleaner nozzle, the sole has two wire-stripping elements located in its part front and sides, as well as two brushes, respectively arranged in front and behind the suction opening. At the back, the squeegee has a wire puller roller. The scraping organs that constitute brushes are fixed, which is allowed by the fact that these brushes are in shrinkage with respect to the fixed wire stripping elements and the roller hard son.
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.The object of the invention is to propose an even simpler nozzle and less expensive to manufacture than the nozzles of the aforementioned prior art, which can be used on all types of soil, without excessive effort on the part of the user, while giving results, as to the quality suction and final cleaning of floors, which are at least comparable to those of the nozzles of the prior art, or even better.
Ce but est atteint dans un suceur d'aspirateur selon la revendication 1. This goal is achieved in a vacuum cleaner nozzle according to claim 1.
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. The present invention, by providing a scraper member which makes continuously protruding under the sole, helps to ensure that it is continuously active and effective.
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.After many tests, we realized that planning a fixed scraper member, insofar as this is fitted to a nozzle said "to floating body "(ie a nozzle in which the pivot axis of the connection sleeve is located behind the axis of rotation of the rear wheels or is at most confused with the latter), and in the extent that said scraper member is located in an area of the nozzle which extends in front of the rear edge of the suction opening, gives excellent results in terms of suction quality and does not require the user to make significant efforts to move the squeegee on the floor, whether it is a carpet or a carpet 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 user simply rolls rear wheels and allow the displacement of the squeegee, without pressing the latter against the ground, it is only under the effect of the depression generated by the suction that the floating body nozzle is pressed against the ground. The fact using a fixed scraper member eliminates the need for provide means for controlling the movement of the scraper member, or even means for automatically urging the scraper member towards its active position or to its inactive position. Whatever the meaning of displacement of the squeegee on the ground, the scraper member occupies the same position and its efficiency is constantly assured.
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 into a region front of the squeegee relative to the rear edge of the suction opening helps to give the nozzle maximum efficiency. Indeed, from apart, the scraper member is far enough away from the rear wheels to that indeed 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 ground. In addition, thanks to this available, the squeegee 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 efficiency of suction is everything quite satisfactory insofar as, when the nozzle is pushed, the dust detached from the ground by the scraper member is then vacuumed in the suction opening. We thus obtain a good compromise between the pushing forces to be applied to move the squeegee on the ground and dust removal. To reduce pushing efforts necessary while maintaining the same results in terms dust removal, we choose advantageously to place the axis sleeves pivot closer to the ground than in the squeegees traditional floating bodies, for example by reducing the radius of the wheels back.
Selon l'invention, 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 the invention, the scraper member is arranged in the suction channel and over at least part of the length of the said channel channel, separates the latter into a portion of front channel and a portion of rear channel.
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 pushing the squeegee, and the dust pushed back when pulling on the squeegee are perfectly sucked. In addition, the scraper member is "self-cleaning", since the depression created by aspiration is exerted in the suction channel, that is to say in the region in which the scraper member is placed, and cleans this last.
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'aspiration 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 have consisted in measuring the suction capacity on this carpet of a vacuum cleaner equipped, first, with a squeegee not comprising a scraper member and, then, of a nozzle of the same type, but with a scraper member disposed in the suction channel according to the above-mentioned arrangement. We found that the efficiency, in terms of dusting the carpet, was higher about 10% 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 depression in the portion rear channel, which further pushes the squeegee to the ground and confines the dust in the rear channel portion, before sucking it in the suction opening, without increasing the efforts too much must exercise the user moving the nozzle on the floor.
L'invention sera bien comprise et ses avantages apparaítront mieux à la lecture de la description qui suit, d'un mode de réalisation représenté à titre d'exemple non limitatif. La description se réfère aux dessins annexés sur lesquels :
- 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 II-II de la figure 3, et
- la figure 3 montre le même suceur en coupe longitudinale dans le plan III-III de la figure 2.
- FIG. 1 shows, in perspective and in view from below, a nozzle according to the invention,
- FIG. 2 shows the squeegee of FIG. 1 in section in an anteroposterior plane along line II-II of FIG. 3, and
- 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 boítier
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
boítier et munie d'une ouverture d'aspiration 16.The figures show a vacuum cleaner nozzle including a
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 boítier 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". In the following, we will consider that the front parts of the various
elements which will be described will be those which are furthest from
the opening 12A of the
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.The squeegee also includes a
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 seen in particular in Figures 1 and 2, the
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.The
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.Wall elements, respectively 19A and 19B close
substantially the rear channel portion 18D on the sides of the sole.
More precisely, as can be seen in FIG. 2, these elements of
walls extend downwards when the nozzle is placed on the floor
substantially to the same level as the front and
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
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.Alternatively, the scraper member may be formed by a strip of plastic material, also suitably chosen not to bend on itself when moving the squeegee.
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.If necessary, one can choose to provide the scraper member with slots
transverse to create small suction passages for
dust, which will be particularly advantageous if, according to a variant
not shown, the scraper member is located at the front of the
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.The two
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 boítier (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 sole of the vacuum cleaner nozzle according to the invention has
simple geometry and, as can be understood in Figure 2, can
optionally be molded in one piece with the
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 boítier 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.This possibility of making the sole and the sole in one
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.By extending the suction opening, a
second hollow suction channel (not shown), located behind the
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.It is also possible to have a
