Definitions
- the present invention relates to the field of vacuum cleaners equipped with a suction head for sucking dust and small-size waste present on a surface.
- the invention aims to design a suction head easily adaptable according to the nature of the surface to be sucked.
- Aspirators equipped with a suction head are well known on the market, they allow to clean surfaces by suction for the evacuation of dust and small size waste based on them.
- the surface to be vacuumed can be for example tiled, parquet, laminate, carpet or carpet. It is therefore best to adapt the suction head sweeping the surface according to the nature of it.
- the suction head traditionally comprises a connecting sleeve and a sole, which comprises a lower face with a cavity extending transversely on the head, said cavity communicating with said sleeve via a rigid or flexible conduit.
- the underside of the soleplate is positioned adjacent to the surface to be sucked during use of the suction head.
- the suction head comprises a set of two brushes arranged at the front and rear of the sole, each on one side of the cavity.
- a mechanism operated by a joystick allows to define three positions of the game of two brushes. According to a first position of the joystick, favorable for use on carpet with long bristles, the mechanism raises the brushes recessed vis-à-vis the underside of the sole which thus rests on the suction surface. According to a second position of the joystick, favorable for use on hard floors, the mechanism descends the brushes protruding vis-à-vis said lower face which is thus detached from the suction surface, the brushes being in contact with said surface. According to a third position of the joystick, favorable for use on compact carpet or short pile, the mechanism inclines the set of brushes relative to said lower face, the rear brush being projecting vis-à-vis that and the front brush set back.
- the sole and the connecting sleeve of the suction head communicate with each other through a rigid fork-shaped tube.
- the tube is articulated, on the one hand, with the sleeve at the axis of the support wheels on the surface to be sucked and, on the other hand, with the sole at an axis parallel to the axis. wheels.
- the suction head comprises a mechanism actuated by a lever, for projecting or withdrawing a set of two brushes vis-à-vis the underside of the sole, down or up.
- One of the brushes is disposed at the front of the sole and the other at the back, each on one side of the cavity.
- the sole and the connecting sleeve of the suction head are connected via a connecting rod mounted in pivot connection, on the one hand, with the soleplate along a first axis and, on the other hand, with the sleeve along a second axis, said axes being parallel to each other and with the axis of rotation of support wheels on the surface to be sucked.
- the sole comprises two angular stops and the connecting rod comprises at its front end an arm which comes into contact against the angular stops during pivoting upwards or downwards of the soleplate relative to the connecting rod.
- the sole comprises on its underside two edges disposed respectively at the front and rear of the cavity.
- the arm comes into contact with the upper angular abutment, which brings the front edge into contact with the surface to be sucked while the rear edge is slightly peeled off this surface.
- the arm comes into contact against the lower angular abutment, which contacts the rear edge on the surface to be sucked while the front edge is slightly peeled off. this surface.
- the contact of an edge with said surface makes it possible to scrape it and, conversely, the detachment of the edge vis-à-vis the latter makes it possible to let a stream of air into the cavity.
- the sole and the connecting sleeve of the suction head are connected by means of a coupling part allowing an angular displacement between said parts.
- the coupling member is pivotally connected to the soleplate and includes a trunnion-receiving lumen arranged on the sleeve that pivots in and slides along the lumen.
- a mechanism actuated by a joystick makes it possible to raise or lower a brush inside the soleplate depending on the nature of the soil to be sucked.
- the present invention aims to design a suction head to better adapt to the nature of the surface to be sucked, the adaptation being done by the action of a single handle to facilitate the use of the vacuum cleaner and visualization of the use position.
- the first position is favorable for use on smooth floors such as a tiled, parquet or laminate surface.
- the second position is favorable for use on carpet or carpet.
- the third position advantageously makes it possible to constrain the soleplate to tilt in a position favoring the scraping of the surface to be sucked. These different positions are obtained simply by operating the lever, which greatly facilitates the use of the suction head.
- the mechanism comprises two angular stops configured to approach one vis-à-vis the other when actuating the handle of the first position to the third position, and conversely to deviate upon actuation of the joystick from the third position to the first position.
- a low angular abutment will be fixed and a stop angular high will be mobile, but we could consider a mechanism on which the high and low angular stops are both mobile and move closer to each other.
- These angular stops are intended to limit the pivoting of the fork relative to the sole, to reach the blockage between the fork and the sole in the third position of the joystick.
- the mechanism is configured so that, in the third position of the lever, the locking of the fork wedges it in the tilted position forward vis-à-vis the sole, which tends to lift the fork and the sleeve relative to the sole.
- the fork is configured to ballast the sole, in particular because of the lifting of the latter and the sleeve vis-à-vis the sole, which forces the inclination towards the rear of said sole due to the wedging , thus positioning it in a preferential position of scraping the surface to be sucked.
- this inclination is made at an angle of seven to ten degrees, preferably eight to nine degrees.
- the mechanism is configured so that, in the second position of the lever, the pivoting of the fork is limited when it tilts backwards.
- This limitation of pivoting and the ballast generated by the configuration of the sole and the sleeve also force the inclination towards the rear of the sole.
- this inclination is effected by an angle of one to three degrees, preferably of two degrees.
- a transverse axis pivot connection is arranged between the handle and the sole, this lever being preferably arranged on the top of the sole to facilitate its accessibility with the foot or the hand.
- the mechanism comprises at least one high stop piece and means for securing the stop piece to the handle, the fork comprising at least one support piece arranged to come into contact with the at least one piece stop when the fork is tilted backwards.
- two stop pieces are distributed over the lateral parts of the suction head and two support pieces are arranged in correspondence with said stop pieces.
- the mechanism comprises at least one low abutment piece, the fork comprising at least one support piece arranged to come into contact with the at least one low abutment piece when a tilting forward of the fork.
- the at least one abutment piece is implemented directly by the upper part of the sole, the at least one bearing part of the fork coming into contact therewith.
- the suction head object of the invention comprises a stop system of the handle and the mechanism according to the three positions.
- the stop system comprises in addition, or alternatively, at least one protuberance on the sole and at least one abutment plate coming into contact with said protuberance when returning to the first position of the joystick and mechanism. This ensures proper stopping of the brushes in protruding position vis-à-vis the underside of the sole.
- return means are configured to participate in the ascent of the at least one brush when moving the handle from the first position to the second position.
- the suction head comprises two brushes respectively arranged on the front side and the rear side of the sole, each on one side of the cavity.
- the underside of the sole comprises a front portion and a rear portion, the rear portion being inclined upwardly vis-à-vis the front portion.
- the front part is more or less parallel to the surface to be sucked and when the sole is tilted backwards, in the third position, the edge between the front part and the rear part. is in contact with said surface.

- the lugs 59 and 61 are respectively housed in the grooves 62 when the parts 22-23 are mounted on the sole 5, said lugs 59 and 61 coming to bear slightly in the bottom of these grooves 62. Due to the flexibility of the legs stop 58 and 60, the lugs 59 and 61 penetrate inside the orifices 63-64 when they correspond, which stops the position of the parts 22-23 and, consequently, that of the lever 20. The lever 20 and the mechanism are in second position in this configuration.
- the flexibility of the stop tabs 58 and 60 allows the release of the lugs 59 and 61 outside the orifices 63-64, thus enabling actuation of the mechanism 21 and the lever 20.
- the lugs 59 and 61 then move in the respective grooves 62 to come, in one direction, in abutment against the first ends 62a of said grooves 62 where the lever 20 and the mechanism 21 have reaches the first position or, in the other direction, in abutment against the second ends 62b of said grooves 62 where the handle 20 and the mechanism 21 have reached the third position.

The invention aims to design a suction head easily adaptable according to the nature of the surface to be sucked.
Les aspirateurs équipés d'une tête de succion sont bien connus sur le marché, ceux-ci permettant de nettoyer des surfaces par aspiration pour l'évacuation des poussières et des déchets de faible granulométrie reposant sur celles-ci.Aspirators equipped with a suction head are well known on the market, they allow to clean surfaces by suction for the evacuation of dust and small size waste based on them.
La surface à aspirer peut être par exemple du carrelage, du parquet, du stratifié, de la moquette ou un tapis. Il convient donc de pouvoir adapter au mieux la tête de succion balayant la surface en fonction de la nature de celle-ci.The surface to be vacuumed can be for example tiled, parquet, laminate, carpet or carpet. It is therefore best to adapt the suction head sweeping the surface according to the nature of it.
La tête de succion comprend traditionnellement un manchon de raccordement et une semelle, laquelle comprend une face inférieure avec une cavité s'étendant transversalement sur la tête, ladite cavité communiquant avec ledit manchon par l'intermédiaire d'un conduit rigide ou flexible. La face inférieure de la semelle est positionnée de manière attenante à la surface à aspirer durant l'utilisation de la tête de succion.The suction head traditionally comprises a connecting sleeve and a sole, which comprises a lower face with a cavity extending transversely on the head, said cavity communicating with said sleeve via a rigid or flexible conduit. The underside of the soleplate is positioned adjacent to the surface to be sucked during use of the suction head.

La présente invention a pour objectif de concevoir une tête de succion permettant de s'adapter au mieux à la nature de la surface à aspirer, l'adaptation se faisant par l'action d'une seule manette afin de faciliter l'utilisation de l'aspirateur et la visualisation de la position d'utilisation.The present invention aims to design a suction head to better adapt to the nature of the surface to be sucked, the adaptation being done by the action of a single handle to facilitate the use of the vacuum cleaner and visualization of the use position.
A cet effet, l'invention concerne une tête de succion d'aspirateur qui comprend :
- une semelle munie d'une face inférieure et d'une cavité débouchant sur cette face inférieure ;
- au moins une brosse qui s'étend transversalement sur la semelle ;
- un manchon de raccordement configuré pour communiquer avec la cavité par l'intermédiaire d'un tube flexible ;
- une fourche agencée entre la semelle et le manchon et montée en liaisons pivots d'axes transversaux vis-à-vis de ladite semelle et dudit manchon.
- a sole provided with a lower face and a cavity opening on this lower face;
- at least one brush extending transversely on the sole;
- a connecting sleeve configured to communicate with the cavity via a flexible tube;
- a fork arranged between the sole and the sleeve and mounted in pivot connections of transverse axes vis-à-vis said sole and said sleeve.
En outre, selon l'invention, la tête de succion comprend un mécanisme et une manette, ladite manette étant configurée pour actionner ledit mécanisme selon trois positions, ledit mécanisme étant configuré pour :
- dans la première position, descendre l'au moins une brosse et la positionner en saillie sur la face inférieure en laissant pivoter la fourche par rapport à la semelle ;
- dans la seconde position, monter l'au moins une brosse et la positionner en retrait de la face inférieure en laissant pivoter la fourche par rapport à la semelle ;
- dans la troisième position, maintenir l'au moins une brosse en retrait de la face inférieure en bloquant la fourche vis-à-vis de la semelle.
- in the first position, lowering the at least one brush and positioning it projecting on the lower face by allowing the fork to pivot relative to the sole;
- in the second position, mount the at least one brush and position it back from the lower face by allowing the fork to pivot relative to the sole;
- in the third position, hold the at least one brush back from the underside by blocking the fork vis-à-vis the sole.
La première position est favorable à une utilisation sur des sols lisses tels qu'une surface carrelée, parquetée ou stratifiée. La seconde position est favorable à une utilisation sur de la moquette ou un tapis. La troisième position permet avantageusement de contraindre la semelle à s'incliner dans une position favorisant le grattage de la surface à aspirer. Ces différentes positions sont obtenues simplement en actionnant la manette, ce qui facilite grandement l'utilisation de la tête de succion.The first position is favorable for use on smooth floors such as a tiled, parquet or laminate surface. The second position is favorable for use on carpet or carpet. The third position advantageously makes it possible to constrain the soleplate to tilt in a position favoring the scraping of the surface to be sucked. These different positions are obtained simply by operating the lever, which greatly facilitates the use of the suction head.
Dans une réalisation de la tête de succion selon l'invention, le mécanisme comprend deux butées angulaires configurées pour se rapprocher l'une vis-à-vis de l'autre lors de l'actionnement de la manette de la première position jusqu'à la troisième position, et inversement pour s'écarter lors de l'actionnement de la manette de la troisième position jusqu'à la première position. Dans une réalisation préférentielle, une butée angulaire basse sera fixe et une butée angulaire haute sera mobile, mais on pourrait envisager un mécanisme sur lequel les butées angulaires haute et basse sont toutes les deux mobiles et se rapprochent l'une de l'autre. Ces butées angulaires ont pour but de limiter le pivotement de la fourche par rapport à la semelle, jusqu'à atteindre le blocage entre la fourche et la semelle dans la troisième position de la manette.In one embodiment of the suction head according to the invention, the mechanism comprises two angular stops configured to approach one vis-à-vis the other when actuating the handle of the first position to the third position, and conversely to deviate upon actuation of the joystick from the third position to the first position. In a preferred embodiment, a low angular abutment will be fixed and a stop angular high will be mobile, but we could consider a mechanism on which the high and low angular stops are both mobile and move closer to each other. These angular stops are intended to limit the pivoting of the fork relative to the sole, to reach the blockage between the fork and the sole in the third position of the joystick.
Dans une réalisation de la tête de succion selon l'invention, le mécanisme est configuré pour que, dans la troisième position de la manette, le blocage de la fourche cale celle-ci en position basculée vers l'avant vis-à-vis de la semelle, ce qui tend à soulever la fourche et le manchon par rapport à la semelle. En outre, la fourche est configurée pour lester la semelle, notamment du fait du soulèvement de celle-ci et du manchon vis-à-vis de la semelle, ce qui force l'inclinaison vers l'arrière de ladite semelle du fait du calage, la positionnant ainsi dans une position préférentielle de grattage de la surface à aspirer. De préférence, cette inclinaison s'effectue d'un angle de sept à dix degrés, préférentiellement de huit à neuf degrés.In one embodiment of the suction head according to the invention, the mechanism is configured so that, in the third position of the lever, the locking of the fork wedges it in the tilted position forward vis-à-vis the sole, which tends to lift the fork and the sleeve relative to the sole. In addition, the fork is configured to ballast the sole, in particular because of the lifting of the latter and the sleeve vis-à-vis the sole, which forces the inclination towards the rear of said sole due to the wedging , thus positioning it in a preferential position of scraping the surface to be sucked. Preferably, this inclination is made at an angle of seven to ten degrees, preferably eight to nine degrees.
Dans une réalisation de la tête de succion selon l'invention, le mécanisme est configuré pour que, dans la seconde position de la manette, le pivotement de la fourche soit limité lors de son basculement vers l'arrière. Cette limitation du pivotement et le lestage généré par la configuration de la semelle et du manchon forcent également l'inclinaison vers l'arrière de la semelle. De préférence, cette inclinaison s'effectue d'un angle d'un à trois degrés, préférentiellement de deux degrés.In an embodiment of the suction head according to the invention, the mechanism is configured so that, in the second position of the lever, the pivoting of the fork is limited when it tilts backwards. This limitation of pivoting and the ballast generated by the configuration of the sole and the sleeve also force the inclination towards the rear of the sole. Preferably, this inclination is effected by an angle of one to three degrees, preferably of two degrees.
Selon la tête de succion objet de l'invention, une liaison pivot d'axe transversal est agencée entre la manette et la semelle, cette manette étant préférentiellement agencée sur le dessus de la semelle pour faciliter son accessibilité avec le pied ou la main. En outre, le mécanisme comprend au moins une pièce de butée haute et des moyens d'assujettissement de la pièce de butée à la manette, la fourche comprenant au moins une pièce d'appui agencée pour venir en contact contre l'au moins une pièce de butée haute lors d'un basculement vers l'arrière de la fourche. De préférence, deux pièces de butée haute sont réparties sur les parties latérales de la tête de succion et deux pièces d'appui sont agencées en correspondance avec lesdites pièces de butée.According to the suction head object of the invention, a transverse axis pivot connection is arranged between the handle and the sole, this lever being preferably arranged on the top of the sole to facilitate its accessibility with the foot or the hand. In addition, the mechanism comprises at least one high stop piece and means for securing the stop piece to the handle, the fork comprising at least one support piece arranged to come into contact with the at least one piece stop when the fork is tilted backwards.
