Definitions
- the present invention relates to the field of vacuum cleaners and relates particularly to the design of the vacuum nozzle, also called suction head or suction head, which are sucked dust.
- the invention aims to design a suction nozzle which ensures optimal suction over the entire surface to be sucked, despite the possible presence of obstacles.
- vacuum cleaners trolley type vacuum or brush type vacuum comprises a nozzle consisting of a head having either a rectangular shape or a triangular shape.
- suckers with rectangular head can effectively dust all types of surfaces, such as carpets, carpets, smooth floors, floors or other, the most difficult to achieve performance on carpets.
- the arrival of energy labels in the field of vacuum cleaners has led manufacturers to reduce the power of the vacuum cleaner motors and thus the air flow sucked in and to develop rectangular suckers maintaining maximum suction performance with a lower suction airflow.
- each vacuum cleaner with two suckers, one consisting of a rectangular head and the other consisting of a triangular head, in order to have optimal performance in all circumstances (clear surfaces or in the presence of obstacles such as a corner of a room, a plinth or furniture).
- the nozzle consists of a suction head having two rectangular side elements adapted to fold for suction in the corners of rooms.
- the present invention aims to design a nozzle to overcome the aforementioned drawbacks.
- the invention relates to a vacuum nozzle designed to be moved on a surface to be sucked.
- the nozzle comprises a first, preferably rectangular head, which comprises a first suction pipe connected to a first suction mouth arranged on a lower face of said first head.
- the nozzle comprises a second head, preferably triangular, which extends forwardly the first head.
- the second head comprises a second suction duct connected to a second suction mouth arranged on a lower face of said second head.
- the nozzle comprises a hinge system arranged between the second head and the first head.
- the hinge system is configured to allow at least one inclination of the lower face of the first head relative to the surface to be sucked while maintaining an orientation of the lower face of the second head substantially fixed with respect to said surface to be sucked during the movements back and forth, and vice versa, said nozzle.
- the first head can rotate freely in at least one direction relative to the surface to be sucked.
- the second head can pivot about an axis parallel to the surface to be sucked and preferably around an axis perpendicular to the direction of movement of the nozzle back and forth on the surface to be sucked.
- the first head of the nozzle according to the invention can operate and position itself on the surface to be sucked substantially independently of the second suction head.
- the first suction head can therefore function in a manner similar to the way it behaves when it is not associated with a second head.
- Such a characteristic therefore makes it possible to obtain a sucker with two suction heads comprising a first suction head resuming the shape and the main elements constituting a suction head whose performance has already been qualified when it is used. only as a nozzle and to associate a second suction head without this too disrupts the behavior of the first head and degrades too much performance on the surface to be sucked during the movements of back and forth of the nozzle.
- the nozzle according to the invention has the advantage of being constituted by a first head, which can be standard and marketed in large quantities without being associated with the second head, and a second more specific head that differentiates the nozzle according to the invention of the nozzle constituted by the single first head to provide additional functionality such as dust removal in a difficult to access area.
- the nozzle thus produced may comprise a first head incorporating all the advantageous functions of the suckers, in particular those with a rectangular head, which currently exist, such as the functions making it possible to perform angular wedging of the head, for example to scrape the surface while by aspiring him.
- the latter comprises at least one connecting rod whose two ends are mounted in pivot connection respectively on the first head and on the second head.
- the articulation system comprises two connecting rods.
- the second head comprises a ground clearance greater than that of the first head. This makes it possible to maintain all the efficiency of the dust collection, in particular during carpet-type surface suction; this greater ground clearance for the second head, disposed in front of the first head, ensures in fact that the underside of said second head does not touch the surface, especially in the case of carpets, which would have the effect of retaining the dust on the surface during aspiration by the first head.
- the nozzle comprises distributing means for modifying the distribution of the suction between the first suction mouth and the second suction mouth.
- Such a feature allows to have a nozzle whose suction performance and ergonomics of use can be greatly modified by changing the distribution of suction between the two heads. It is thus possible to obtain a nozzle whose suction performance approaches that of the first head used alone, the second head used alone or a mix of the two heads.
- the distribution means can occupy a first position in which they allow suction only by the first suction mouth and at least a second position in which they allow aspiration at least by the second suction mouth .
- Such a nozzle has the advantage of being able to be used with a position of the distributor means in which the suction takes place only through the first head, making it possible to obtain suction performance similar to the nozzle usually only constituted by the first head.
- the nozzle can combine both the performance of the first head, which has been the subject of in-depth studies and whose suction performance has been optimized to successfully pass the various performance tests, and those of a second head providing additional functionality such as dusting in a difficult to access area.
- the distribution means in the second position, can occupy a position in which they allow suction only by the second suction mouth.
- the second head comprises an obstacle detection device and the distribution means are automatically moved to the second position when the detection device detects an obstacle.
- the detection device detects an obstacle.
- the first head has a trapezoidal shape, preferably rectangular.
- Such a characteristic makes it possible to have a nozzle having a first head of usual shape and construction, the performances of which have been tested on other suckers.
- the second head has a width in width smaller than the first head.
- Such a characteristic makes it possible to obtain a nozzle having both a first head having a width sufficient to ensure dust suction over a large width and a second head, arranged in front of the first head, having a smaller width to suck more easily in the corners of the rooms or in the recesses.
- the second head has a shape converging towards a front end of reduced width, the second head advantageously having a triangular shape.
- Such a feature can further optimize the ability of the nozzle to suck in the corners.
- the first head ensures suction of the surface, the suction by the second head being condemned.
- the nozzle meets an obstacle, for example a room angle, a plinth along a wall or furniture, or only the second head ensures suction of the surface, the suction by the first head being condemned, either to both the first head and the second head provide suction.
- the second head is triangular and the stop means comprise two stop bars arranged respectively along the two sides forming the tip of the triangular head.
- the two stop bars are mounted pivotally connected to each other at the tip of the triangular head.
- Other abutment means remain possible within the scope of the invention.
- the orifice is preferably arranged in a bent portion of the first suction duct.
- sealing means are implemented between the shutter and the orifice to ensure a tight closure of said orifice. This seal optimizes suction performance by the first head.
- At least a portion of the intermediate conduit is flexible so as to allow freedom of movement between the first head and the second head. This freedom of movement allows the first head to work freely and correctly during the suction of an unobstructed surface, without interference of the second head.
- the shutter is constituted by a valve mounted in pivot connection, said valve being configured to pivot in a closed position of the orifice or in an open position of the orifice, said valve being configured to close the first suction mouth in its open position of the orifice.
- said sealing means are configured to ensure a seal between the valve and the first suction mouth in the open position of said valve.

Description
La présente invention concerne le domaine des aspirateurs et porte tout particulièrement sur la conception du suceur d'aspirateur, encore appelé tête de succion ou tête d'aspiration, par lequel sont aspirées les poussières.The present invention relates to the field of vacuum cleaners and relates particularly to the design of the vacuum nozzle, also called suction head or suction head, which are sucked dust.
L'invention vise à concevoir un suceur d'aspirateur qui assure une aspiration optimale sur toute la surface à aspirer, malgré la présence éventuelle d'obstacles.The invention aims to design a suction nozzle which ensures optimal suction over the entire surface to be sucked, despite the possible presence of obstacles.
Traditionnellement, les aspirateurs de type aspirateur chariot ou de type aspirateur balai comprennent un suceur constitué d'une tête qui présente soit une forme rectangulaire soit une forme triangulaire.Traditionally, vacuum cleaners trolley type vacuum or brush type vacuum comprises a nozzle consisting of a head having either a rectangular shape or a triangular shape.
Les dernières conceptions de suceurs à tête rectangulaire permettent de dépoussiérer efficacement tous types de surfaces, par exemple les moquettes, les tapis, les sols lisses, les parquets ou autres, les performances les plus difficiles à atteindre étant sur des moquettes. En particulier, l'arrivée des étiquettes énergie dans le domaine des aspirateurs a conduit les constructeurs à réduire la puissance des moteurs d'aspirateur et donc le débit d'air aspiré et à développer des suceurs à tête rectangulaire conservant des performances d'aspiration maximales avec un débit d'air aspiré plus faible.The latest designs of suckers with rectangular head can effectively dust all types of surfaces, such as carpets, carpets, smooth floors, floors or other, the most difficult to achieve performance on carpets. In particular, the arrival of energy labels in the field of vacuum cleaners has led manufacturers to reduce the power of the vacuum cleaner motors and thus the air flow sucked in and to develop rectangular suckers maintaining maximum suction performance with a lower suction airflow.
De tels suceurs à tête rectangulaire ne permettent cependant pas un accès convenable dans les angles de pièces et le long de plinthes. L'efficacité du dépoussiérage est en effet bien meilleure dans les angles de pièces ou le long des plinthes en utilisant un suceur à tête triangulaire.Such suckers with rectangular head, however, do not allow proper access in the corners of rooms and along skirting boards. The effectiveness of dust removal is indeed much better in the corners of rooms or along the skirting boards by using a nozzle with triangular head.
Il conviendrait donc idéalement d'équiper chaque aspirateur de deux suceurs, l'un constitué d'une tête rectangulaire et l'autre constitué d'une tête triangulaire, afin de disposer des performances optimales dans toutes les circonstances (surfaces dégagées ou en présence d'obstacles tels qu'un angle de pièce, une plinthe ou un mobilier).It would therefore be ideal to equip each vacuum cleaner with two suckers, one consisting of a rectangular head and the other consisting of a triangular head, in order to have optimal performance in all circumstances (clear surfaces or in the presence of obstacles such as a corner of a room, a plinth or furniture).
Certaines conceptions de suceurs à tête rectangulaire cherchent à pallier cet inconvénient.Some designs of suckers rectangular head seek to overcome this disadvantage.

La deuxième tête comprend un second conduit d'aspiration raccordé à une seconde bouche d'aspiration agencée sur une face inférieure de ladite deuxième tête.According to the invention, the nozzle comprises a second head, preferably triangular, which extends forwardly the first head. The second head comprises a second suction duct connected to a second suction mouth arranged on a lower face of said second head.
En outre, selon l'invention, le suceur comprend un système d'articulation agencé entre la deuxième tête et la première tête. Le système d'articulation est configuré pour permettre au moins une inclinaison de la face inférieure de la première tête par rapport à la surface à aspirer tout en conservant une orientation de la face inférieure de la deuxième tête sensiblement fixe par rapport à ladite surface à aspirer durant les déplacements d'avant en arrière, et inversement, dudit suceur.In addition, according to the invention, the nozzle comprises a hinge system arranged between the second head and the first head. The hinge system is configured to allow at least one inclination of the lower face of the first head relative to the surface to be sucked while maintaining an orientation of the lower face of the second head substantially fixed with respect to said surface to be sucked during the movements back and forth, and vice versa, said nozzle.
Par inclinaison de la face inférieure de la première tête par rapport à la surface à aspirer on entend que la première tête peut pivoter librement selon au moins une direction par rapport à la surface à aspirer. De manière avantageuse, la deuxième tête peut pivoter autour d'un axe parallèle à la surface à aspirer et préférentiellement autour d'un axe perpendiculaire à la direction de déplacement d'avant en arrière du suceur sur la surface à aspirer.By inclining the lower face of the first head relative to the surface to be sucked is meant that the first head can rotate freely in at least one direction relative to the surface to be sucked. Advantageously, the second head can pivot about an axis parallel to the surface to be sucked and preferably around an axis perpendicular to the direction of movement of the nozzle back and forth on the surface to be sucked.
Ainsi, la première tête du suceur selon l'invention peut fonctionner et se positionner sur la surface à aspirer de façon sensiblement indépendante de la deuxième tête d'aspiration. La première tête d'aspiration peut donc fonctionner en se comportant de manière similaire à la façon dont elle se comporte lorsqu'elle n'est pas associée à une deuxième tête. Une telle caractéristique permet donc d'obtenir un suceur à deux têtes d'aspiration comportant une première tête d'aspiration reprenant la forme et les principaux éléments constitutifs d'une tête d'aspiration dont les performances ont déjà été qualifiées lorsqu'elle est utilisée seule en tant que suceur et de lui associer une deuxième tête d'aspiration sans que cela ne perturbe trop le comportement de la première tête et ne dégrade trop sa performance sur la surface à aspirer lors des mouvements de va-et-vient du suceur.Thus, the first head of the nozzle according to the invention can operate and position itself on the surface to be sucked substantially independently of the second suction head. The first suction head can therefore function in a manner similar to the way it behaves when it is not associated with a second head. Such a characteristic therefore makes it possible to obtain a sucker with two suction heads comprising a first suction head resuming the shape and the main elements constituting a suction head whose performance has already been qualified when it is used. only as a nozzle and to associate a second suction head without this too disrupts the behavior of the first head and degrades too much performance on the surface to be sucked during the movements of back and forth of the nozzle.
Ainsi, le suceur selon l'invention présente l'avantage d'être constitué par une première tête, qui peut être standard et commercialisée en grande quantité sans être associée à la deuxième tête, et d'une deuxième tête plus spécifique qui permet de différencier le suceur selon l'invention du suceur constitué par la seule première tête en permettant d'apporter une fonctionnalité supplémentaire comme par exemple un dépoussiérage dans une zone difficile d'accès. La réutilisation de la première tête, aux performances déjà établies, permet de réduire les coûts de développement et de production du suceur selon l'invention.Thus, the nozzle according to the invention has the advantage of being constituted by a first head, which can be standard and marketed in large quantities without being associated with the second head, and a second more specific head that differentiates the nozzle according to the invention of the nozzle constituted by the single first head to provide additional functionality such as dust removal in a difficult to access area. The reuse of the first head, already established performance, reduces the costs of development and production of the nozzle according to the invention.
En particulier, le suceur ainsi réalisé pourra comporter une première tête reprenant toutes les fonctions avantageuses des suceurs, notamment à tête rectangulaire, existant actuellement, telles que les fonctions permettant d'effectuer un calage angulaire de la tête, par exemple pour gratter la surface tout en l'aspirant.In particular, the nozzle thus produced may comprise a first head incorporating all the advantageous functions of the suckers, in particular those with a rectangular head, which currently exist, such as the functions making it possible to perform angular wedging of the head, for example to scrape the surface while by aspiring him.
Selon une réalisation du système d'articulation, celui-ci comprend au moins une bielle dont les deux extrémités sont montées en liaison pivot respectivement sur la première tête et sur la deuxième tête. De préférence, le système d'articulation comprend deux bielles.According to one embodiment of the articulation system, the latter comprises at least one connecting rod whose two ends are mounted in pivot connection respectively on the first head and on the second head. Preferably, the articulation system comprises two connecting rods.
Selon le suceur objet de l'invention, la deuxième tête comprend une garde au sol plus importante que celle de la première tête. Cela permet de conserver toute l'efficacité du dépoussiérage, notamment lors de l'aspiration de surface de type moquette ; cette garde au sol plus importante pour la deuxième tête, disposée devant la première tête, garantit en effet que la face inférieure de ladite deuxième tête ne touche pas la surface, notamment dans le cas de moquettes, ce qui aurait pour incidence de retenir la poussière sur la surface durant l'aspiration par la première tête.According to the nozzle object of the invention, the second head comprises a ground clearance greater than that of the first head. This makes it possible to maintain all the efficiency of the dust collection, in particular during carpet-type surface suction; this greater ground clearance for the second head, disposed in front of the first head, ensures in fact that the underside of said second head does not touch the surface, especially in the case of carpets, which would have the effect of retaining the dust on the surface during aspiration by the first head.
Selon une caractéristique avantageuse de l'invention, le suceur comprend des moyens répartiteurs permettant de modifier la répartition de l'aspiration entre la première bouche d'aspiration et la seconde bouche d'aspiration.According to an advantageous characteristic of the invention, the nozzle comprises distributing means for modifying the distribution of the suction between the first suction mouth and the second suction mouth.
Une telle caractéristique permet d'avoir un suceur dont les performances d'aspiration et l'ergonomie d'utilisation peuvent être fortement modifiées en modifiant la répartition de l'aspiration entre les deux têtes. On peut ainsi obtenir un suceur dont les performances d'aspiration s'approchent de celle de la première tête utilisée seule, de la deuxième tête utilisée seule ou d'un mix des deux têtes.Such a feature allows to have a nozzle whose suction performance and ergonomics of use can be greatly modified by changing the distribution of suction between the two heads. It is thus possible to obtain a nozzle whose suction performance approaches that of the first head used alone, the second head used alone or a mix of the two heads.
Selon une conception préférentielle du suceur, les moyens répartiteurs peuvent occuper une première position dans laquelle ils permettent une aspiration uniquement par la première bouche d'aspiration et au moins une deuxième position dans laquelle ils permettent une aspiration au moins par la seconde bouche d'aspiration.According to a preferred design of the nozzle, the distribution means can occupy a first position in which they allow suction only by the first suction mouth and at least a second position in which they allow aspiration at least by the second suction mouth .
Un tel suceur présente l'avantage de pouvoir être utilisé avec une position des moyens répartiteurs dans laquelle l'aspiration ne s'effectue qu'au travers de la première tête, permettant d'obtenir des performances d'aspiration similaires au suceur habituellement constitué uniquement par la première tête.Such a nozzle has the advantage of being able to be used with a position of the distributor means in which the suction takes place only through the first head, making it possible to obtain suction performance similar to the nozzle usually only constituted by the first head.
Ainsi, le suceur peut combiner à la fois les performances de la première tête, qui a pu faire l'objet d'études approfondies et dont les performances d'aspiration ont été optimisées pour passer avec succès les différents tests de performance, et celles d'une deuxième tête offrant une fonctionnalité supplémentaire comme par exemple un dépoussiérage dans une zone difficile d'accès.Thus, the nozzle can combine both the performance of the first head, which has been the subject of in-depth studies and whose suction performance has been optimized to successfully pass the various performance tests, and those of a second head providing additional functionality such as dusting in a difficult to access area.
Selon une conception du suceur, dans la deuxième position, les moyens répartiteurs peuvent occuper une position dans laquelle ils permettent une aspiration uniquement par la seconde bouche d'aspiration.According to a design of the nozzle, in the second position, the distribution means can occupy a position in which they allow suction only by the second suction mouth.
Selon une autre conception du suceur, la deuxième tête comporte un dispositif de détection d'un obstacle et les moyens répartiteurs sont déplacés automatiquement dans la deuxième position lorsque le dispositif de détection détecte un obstacle.
Une telle caractéristique permet de privilégier l'aspiration au plus près de l'obstacle lorsque le suceur rencontre un obstacle telle une plinthe.According to another design of the nozzle, the second head comprises an obstacle detection device and the distribution means are automatically moved to the second position when the detection device detects an obstacle.
Such a characteristic makes it possible to favor suction as close as possible to the obstacle when the nozzle meets an obstacle such as a skirting board.
Selon une autre conception du suceur, la première tête présente une forme trapézoïdale, avantageusement rectangulaire.According to another design of the nozzle, the first head has a trapezoidal shape, preferably rectangular.
Une telle caractéristique permet d'avoir un suceur présentant une première tête de forme et construction habituelles, dont les performances ont été éprouvées sur d'autres suceurs.Such a characteristic makes it possible to have a nozzle having a first head of usual shape and construction, the performances of which have been tested on other suckers.
Selon une autre conception du suceur, la deuxième tête présente un encombrement en largeur plus faible que la première tête.According to another design of the nozzle, the second head has a width in width smaller than the first head.
Une telle caractéristique permet d'obtenir un suceur présentant à la fois une première tête présentant une largeur suffisante pour assurer une aspiration des poussières sur une grande largeur et une deuxième tête, disposée devant la première tête, présentant une largeur moindre pour aspirer plus facilement dans les angles des pièces ou dans les recoins.Such a characteristic makes it possible to obtain a nozzle having both a first head having a width sufficient to ensure dust suction over a large width and a second head, arranged in front of the first head, having a smaller width to suck more easily in the corners of the rooms or in the recesses.
Selon une conception du suceur, la deuxième tête présente une forme convergeant vers une extrémité avant de largeur réduite, la deuxième tête présentant avantageusement une forme triangulaire.According to a design of the nozzle, the second head has a shape converging towards a front end of reduced width, the second head advantageously having a triangular shape.
Une telle caractéristique permet d'optimiser encore la faculté du suceur à aspirer dans les coins.Such a feature can further optimize the ability of the nozzle to suck in the corners.
Selon une conception du suceur, les moyens répartiteurs comportent un système d'aiguillage comprenant :
- un conduit intermédiaire qui comprend une extrémité avant et une extrémité arrière, l'extrémité avant étant raccordée à une extrémité arrière du second conduit d'aspiration et l'extrémité arrière débouchant sur un orifice agencé sur le premier conduit d'aspiration,
- un obturateur configuré pour être déplacé dans une position de fermeture de l'orifice et dans une position d'ouverture l'orifice,
- des moyens de commande permettant de déplacer l'obturateur de sa position de fermeture à sa position d'ouverture et vice-versa.
- an intermediate duct which comprises a front end and a rear end, the front end being connected to a rear end of the second duct suction and the rear end opening on an orifice arranged on the first suction duct,
- a shutter configured to be moved into a closed position of the orifice and in an open position the orifice,
- control means for moving the shutter from its closed position to its open position and vice versa.
Selon une conception du suceur, les moyens de commande comprennent :
- des moyens de butée agencés sur deux côtés au voisinage de l'extrémité avant de la deuxième tête,
- des moyens de transmission agencés entre les moyens de butée et l'obturateur et configurés pour déplacer l'obturateur dans sa position de fermeture en condition normale d'utilisation et dans sa position d'ouverture lorsque les moyens de butée entrent en contact avec l'obstacle.
- stop means arranged on two sides in the vicinity of the front end of the second head,
- transmission means arranged between the stop means and the shutter and configured to move the shutter into its closed position under normal use and in its open position when the stop means comes into contact with the shutter obstacle.
En condition normale d'utilisation, c'est-à -dire lorsque la surface à aspirer est dégagée (sans obstacles), seule la première tête assure une aspiration de la surface, l'aspiration par la deuxième tête étant condamnée. Lorsque le suceur rencontre un obstacle, par exemple un angle de pièce, une plinthe le long d'une paroi ou un mobilier, soit seule la deuxième tête assure une aspiration de la surface, l'aspiration par la première tête étant condamnée, soit à la fois la première tête et la deuxième tête assurent une aspiration.In normal use, that is to say when the surface to be vacuumed is clear (without obstacles), only the first head ensures suction of the surface, the suction by the second head being condemned. When the nozzle meets an obstacle, for example a room angle, a plinth along a wall or furniture, or only the second head ensures suction of the surface, the suction by the first head being condemned, either to both the first head and the second head provide suction.
Selon une conception du suceur, la deuxième tête est triangulaire et les moyens de butée comprennent deux barrettes de butée agencées respectivement sur le long des deux côtés formant la pointe de la tête triangulaire. De préférence, les deux barrettes de butée sont montées en liaison pivot entre elles au niveau de la pointe de la tête triangulaire. D'autres moyens de butée restent envisageables dans le cadre de l'invention.According to a design of the nozzle, the second head is triangular and the stop means comprise two stop bars arranged respectively along the two sides forming the tip of the triangular head. Preferably, the two stop bars are mounted pivotally connected to each other at the tip of the triangular head. Other abutment means remain possible within the scope of the invention.
Selon cette conception préférentielle du suceur, l'orifice est préférentiellement agencé dans une partie coudée du premier conduit d'aspiration.According to this preferred design of the nozzle, the orifice is preferably arranged in a bent portion of the first suction duct.
Selon cette conception préférentielle du suceur, des moyens d'étanchéité sont mis en oeuvre entre l'obturateur et l'orifice pour assurer une fermeture étanche dudit orifice. Cette étanchéité permet d'optimiser les performances d'aspiration par la première tête.According to this preferred design of the nozzle, sealing means are implemented between the shutter and the orifice to ensure a tight closure of said orifice. This seal optimizes suction performance by the first head.
Selon cette conception préférentielle du suceur, au moins une portion du conduit intermédiaire est souple de sorte à laisser une liberté de mouvement entre la première tête et la deuxième tête. Cette liberté de mouvement permet à la première tête de travailler librement et correctement durant l'aspiration d'une surface dégagée, sans interférence de la deuxième tête.According to this preferred design of the nozzle, at least a portion of the intermediate conduit is flexible so as to allow freedom of movement between the first head and the second head. This freedom of movement allows the first head to work freely and correctly during the suction of an unobstructed surface, without interference of the second head.
Selon cette conception préférentielle du suceur, dans une première variante de réalisation, l'obturateur est constitué d'un clapet monté en liaison pivot, ledit clapet étant configuré pour pivoter dans une position de fermeture de l'orifice ou dans une position d'ouverture de l'orifice, ledit clapet étant configuré pour obturer la première bouche d'aspiration dans sa position d'ouverture de l'orifice. Ainsi, le suceur permet une aspiration uniquement par la seconde bouche d'aspiration lorsque la tête triangulaire est en butée contre un obstacle.According to this preferred design of the nozzle, in a first embodiment, the shutter is constituted by a valve mounted in pivot connection, said valve being configured to pivot in a closed position of the orifice or in an open position of the orifice, said valve being configured to close the first suction mouth in its open position of the orifice. Thus, the nozzle allows suction only by the second suction mouth when the triangular head is in abutment against an obstacle.
Selon cette première réalisation de l'obturateur, en la présence des moyens d'étanchéité précités, lesdits moyens d'étanchéité sont configurés pour assurer une étanchéité entre le clapet et la première bouche d'aspiration dans la position d'ouverture dudit clapet.According to this first embodiment of the shutter, in the presence of the aforementioned sealing means, said sealing means are configured to ensure a seal between the valve and the first suction mouth in the open position of said valve.
Selon cette première réalisation de l'obturateur, les moyens de transmission comprennent au moins un bras prolongeant vers l'avant le clapet et au moins un levier monté en liaison pivot et agencé entre l'au moins un bras et les moyens de butée, l'activation des moyens de butée au contact d'un obstacle entraînant le pivotement du clapet en position d'ouverture de l'orifice. De préférence, les moyens de transmission comprennent deux bras sur le clapet et deux leviers agencés respectivement entre les deux bras et les deux barrettes de butée précitées.According to this first embodiment of the shutter, the transmission means comprise at least one arm extending forwards the valve and at least one lever mounted in pivot connection and arranged between the at least one arm and the stop means, activation of the abutment means in contact with an obstacle causing the pivoting of the valve in the open position of the orifice. Preferably, the transmission means comprise two arms on the valve and two levers respectively arranged between the two arms and the two abutment bars mentioned above.
Selon cette première réalisation de l'obturateur, les moyens de transmission comprennent un élément de rappel du clapet en position de fermeture de l'orifice. Ainsi, lorsque le suceur est dégagé de l'obstacle, celui-ci coupe le mode d'aspiration par la deuxième tête et repasse instantanément sur le mode d'aspiration par la première tête.According to this first embodiment of the shutter, the transmission means comprise a return element of the valve in the closed position of the orifice. Thus, when the nozzle is cleared of the obstacle, it cuts the suction mode by the second head and instantly returns to the suction mode by the first head.
Selon la conception préférentielle du suceur, dans une seconde variante de réalisation, l'obturateur comprend une soupape montée en translation dans le conduit intermédiaire, ladite soupape étant configurée pour translater dans une position de fermeture de l'orifice ou dans une position d'ouverture de l'orifice. Ainsi, le suceur permet une aspiration à la fois par la première bouche d'aspiration et par la seconde bouche d'aspiration lorsque la tête triangulaire rencontre un obstacle.According to the preferred design of the nozzle, in a second embodiment, the shutter comprises a valve mounted in translation in the intermediate conduit, said valve being configured to translate into a closed position of the orifice or in an open position of the orifice. Thus, the nozzle allows a suction both by the first suction mouth and the second suction mouth when the triangular head meets an obstacle.
Selon cette seconde variante de réalisation de l'obturateur, les moyens de transmission comprennent une pièce rotative et au moins une bielle agencée entre la pièce rotative et les moyens de butée, l'activation des moyens de butée au contact d'un obstacle entraînant la rotation de la pièce rotative. En outre, les moyens de transmission comprennent un câble agencé entre la pièce rotative et la soupape, la rotation de la pièce rotative permettant au câble de translater la soupape dans la position d'ouverture de l'orifice.According to this second embodiment of the shutter, the transmission means comprise a rotating part and at least one connecting rod arranged between the rotating part and the abutment means, the activation of the abutment means in contact with an obstacle causing the rotation of the rotating part. In addition, the transmission means comprise a cable arranged between the rotating part and the valve, the rotation of the rotating part allowing the cable to translate the valve in the opening position of the orifice.
Selon cette seconde variante de réalisation de l'obturateur, les moyens de transmission comprennent un élément de rappel de la soupape en position de fermeture de l'orifice. Ainsi, lorsque le suceur est dégagé de l'obstacle, celui-ci coupe le mode d'aspiration par la deuxième tête et repasse instantanément sur le mode d'aspiration par la première tête, uniquement.According to this second embodiment of the shutter, the transmission means comprise a return element of the valve in the closed position of the orifice. Thus, when the nozzle is cleared of the obstacle, it cuts the suction mode by the second head and returns instantly to the suction mode by the first head, only.
Selon l'invention, le suceur comprend un embout de raccordement à un tube rigide ou flexible, ledit embout étant connecté à une extrémité arrière du premier conduit d'aspiration.According to the invention, the nozzle comprises a connecting piece to a rigid or flexible tube, said nozzle being connected to a rear end of the first suction duct.
Selon une autre caractéristique de l'invention, l'embout de raccordement est porté par un chariot qui comporte deux roues montées sur un axe.According to another characteristic of the invention, the connection piece is carried by a carriage which comprises two wheels mounted on an axis.
Selon une autre caractéristique de l'invention, le système d'articulation est configuré pour permettre un pivotement de la deuxième tête autour d'un axe parallèle à l'axe de rotation des roues.According to another characteristic of the invention, the articulation system is configured to allow pivoting of the second head about an axis parallel to the axis of rotation of the wheels.
Selon une autre caractéristique de l'invention, le chariot comprend une fourche dont la partie arrière est montée en liaison pivot selon l'axe des roues, d'une part, et dont la partie avant est montée en liaison pivot vis-à -vis de la première tête, d'autre part.According to another characteristic of the invention, the carriage comprises a fork whose rear portion is mounted in pivot connection along the axis of the wheels, on the one hand, and whose front portion is mounted in pivot connection vis-a-vis of the first head, on the other hand.
L'invention concerne également un aspirateur comprenant un suceur présentant l'une et/ou l'autre des caractéristiques décrites précédemment. L'aspirateur sera de préférence de type aspirateur chariot ou de type aspirateur balai, bien connu de l'homme du métier.The invention also relates to an aspirator comprising a nozzle having one and / or the other of the characteristics described above. The vacuum cleaner will preferably be a vacuum cleaner type vacuum or brush type, well known to those skilled in the art.

Dans une réalisation préférentielle, selon les deux variantes décrites précédemment, voire pour d'autres variantes, la garde au sol de la tête triangulaire 3, c'est-à -dire l'espace séparant sa face inférieure 10 de la surface 5, est supérieure à la garde au sol de la tête rectangulaire 2, c'est-à -dire l'espace séparant sa face inférieure 8 de la surface 5. Cette augmentation de la garde au sol de la tête triangulaire 3 a pour but d'éviter de retenir les poussières au niveau de la seconde bouche d'aspiration 4, en particulier lorsque la surface 5 aspirée est de la moquette dont les poils peuvent être plus ou moins longs.In a preferred embodiment, according to the two variants described above, or even for other variants, the ground clearance of the
Les caractéristiques décrites précédemment pour les deux variantes du suceur 1 ne sont pas limitatives, d'autres variantes restant envisageables.The characteristics described above for the two variants of the
A titre d'exemple, la liaison pivot entre les deux barrettes de butée 34, 35 pourrait être remplacée par un montage en translation de ces barrettes de butée 34, 35 vis-à -vis des côtés 36, 37 du corps 22 de la tête triangulaire 3. On pourrait aussi, dans ce cas, remplacer chacune des barrettes de butées 34, 35 par plusieurs éléments de butée. Il conviendrait alors, bien entendu, d'adapter les moyens de transmission permettant l'actionnement du clapet 26 ou de la soupape 60.For example, the pivot connection between the two stop bars 34, 35 could be replaced by a translational mounting of these stop bars 34, 35 vis-à -vis the
Les deux variantes de réalisation décrites en regard des
Bien entendu, l'invention n'est nullement limitée aux modes de réalisation précédemment décrits et illustrés qui n'ont été donné qu'à titre d'exemples. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the previously described and illustrated embodiments which have been given only as examples. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
Ainsi, dans une variante de réalisation non représentée, la deuxième tête pourra être reliée par une articulation directement à l'axe des roues du chariot ou à l'embout de raccordement et non pas à la première tête.Thus, in an alternative embodiment not shown, the second head may be connected by a hinge directly to the axis of the wheels of the carriage or to the connecting end and not to the first head.
Ainsi, dans une variante de réalisation de l'invention non représentée, la première tête pourra comporter une forme différente de celle décrite dans le mode de réalisation illustré ci-dessus. A titre d'exemple, la première tête pourra présenter une forme sensiblement trapézoïdale avec un bord arrière légèrement plus grand que le bord avant. Les bords latéraux de la première tête pourront également être légèrement courbes. La première tête pourra également présenter une forme oblongue. La deuxième tête pourra quant à elle présenter un bord arrière présentant une largeur inférieure ou égale à la largeur du bord avant de la première tête et une forme convergeant vers une extrémité avant de plus faible largeur. Ainsi, la deuxième tête pourra présenter un bord avant de forme arquée présentant par exemple la forme d'un demi-cercle.Thus, in an alternative embodiment of the invention not shown, the first head may have a shape different from that described in the embodiment illustrated above. For example, the first head may have a substantially trapezoidal shape with a rear edge slightly larger than the front edge. The lateral edges of the first head may also be slightly curved. The first head may also have an oblong shape. The second head may have a rear edge having a width less than or equal to the width of the front edge of the first head and a shape converging towards a front end of smaller width. Thus, the second head may have an arcuate front edge having for example the shape of a semicircle.
Ainsi, dans une variante de réalisation non représentée, les moyens répartiteurs permettant de modifier la répartition de l'aspiration entre la première bouche d'aspiration et la seconde bouche d'aspiration pourront comprendre un clapet, ou un obturateur, motorisé et commandé électriquement par des interrupteurs associés aux barrettes de butées disposées sur l'extrémité avant de la deuxième tête. Dans une variante de réalisation, le clapet motorisé ou l'obturateur motorisé pourra également être piloté par une carte électronique en fonction du signal émis par un dispositif de détection d'un obstacle comprenant avantageusement des capteurs de proximité portés par le suceur, ces capteurs de proximité pouvant par exemple être constitués par un capteur optique, un capteur capacitif ou un capteur à ultrasons. Dans une autre variante de réalisation non représentée, le dispositif de détection d'un obstacle pourra également faire appel à une analyse d'image à l'aide d'une caméra.Thus, in an alternative embodiment not shown, the distribution means for changing the distribution of the suction between the first suction mouth and the second suction mouth may comprise a valve, or a shutter, motorized and electrically controlled by switches associated with the stop bars disposed on the front end of the second head. In an alternative embodiment, the motorized valve or the motorized shutter may also be controlled by an electronic card according to the signal emitted by an obstacle detection device advantageously comprising proximity sensors carried by the nozzle, these sensors of proximity may for example be constituted by an optical sensor, a capacitive sensor or an ultrasonic sensor. In another variant embodiment not shown, the device for detecting an obstacle may also use an image analysis using a camera.
Dans une autre variante de réalisation non représentée, les moyens répartiteurs pourront comprendre un clapet, ou un obturateur, dont le positionnement est commandé mécaniquement ou électriquement au moyen d'un bouton de commande permettant à l'utilisateur de sélectionner manuellement le mode de fonctionnement du suceur qu'il souhaite utiliser parmi différents modes de fonctionnement proposés tels que : aspiration uniquement au travers de la première tête, aspiration uniquement au travers de la deuxième tête, ou aspiration combinée au travers des deux têtes.In another variant embodiment not shown, the splitter means may comprise a valve, or a shutter, whose positioning is controlled mechanically or electrically by means of a control button allowing the user to manually select the operating mode of the nozzle that it wishes to use among different modes of operation proposed such as: aspiration only through the first head, suction only through the second head, or combined suction through both heads.
