Description

ASPIRATEUR À FEUILLES SHEET VACUUM CLEANER
Domaine de l'inventionField of the invention
La présente invention a pour objet un aspirateur à usage horticole ou agricole destiné en particulier mais non exclusivement à aspirer des feuilles ou des débris présents sur un gazon.The present invention relates to a horticultural or agricultural vacuum cleaner intended in particular but not exclusively to suck leaves or debris present on a turf.
Description de l'art antérieurDescription of the prior art
II est bien connu que les aspirateurs à feuilles comprennent habituellement une turbine d'aspiration placée entre une entrée d'air par laquelle les feuilles ou les débris sont aspirés et un réservoir ou un sac, dans lesquels ils sont récupérés.It is well known that leaf cleaners usually comprise a suction turbine placed between an air inlet through which the leaves or debris are sucked and a tank or bag into which they are recovered.
II est également connu que la force d'aspiration d'un aspirateur dépend entre autres de la taille de la turbine utilisée, du nombre de pales qu'elle contient et de la vitesse à laquelle elle tourne. En fait, le choix de la turbine dépend de la distance entre la turbine et l'orifice du bec de l'aspirateur. Plus la force d'aspiration nécessaire au bon fonctionnement d'un aspirateur est grande, plus l'utilisation de ce dernier est énergivore et occasionne du bruit.It is also known that the suction force of a vacuum cleaner depends inter alia on the size of the turbine used, the number of blades it contains and the speed at which it rotates. In fact, the choice of turbine depends on the distance between the turbine and the mouth of the nozzle of the vacuum cleaner. The greater the suction force required for the operation of a vacuum cleaner, the more the use of the latter is energy-consuming and causes noise.
La demande de brevet des Etats-Unis N° 2005/0229571 A1 (SATOSKI, D. J.), décrit un aspirateur à feuilles comprenant une turbine aspirante positionnée horizontalement dans un bec circulaire, mais relativement loin du réservoir à déchets. L'aspiration doit donc être suffisamment forte pour permettre aux débris d'être projetés dans le réservoir. ;U.S. Patent Application No. 2005/0229571 A1 (SATOSKI, D.J.) discloses a leaf cleaner comprising a suction turbine positioned horizontally in a circular spout, but relatively far from the waste container. The suction must be strong enough to allow debris to be thrown into the tank. ;
Le brevet français N° 2.571.587 (GARNOT, G.R.C.) décrit un aspirateur ayant une turbine positionnée à mi-chemin entre le bec aspirant et le réservoir. Les distances entre le bec et la turbine et la turbine et le réservoir sont là encore importantes et implique donc l'utilisation d'une grande force d'aspiration. Les turbines généralement décrites dans l'art antérieur sont constituées d'une ou plusieurs pales positionnées sur une seule des deux faces de la turbine. On peut se référer à ce sujet aux brevets des Etats-Unis Nos 5.340.035, 5.707.017 et 4.426.830. Il en résulte l'utilisation d'une grande vitesse de rotation de la turbine pour créer une force d'aspiration optimale.French Patent No. 2,571,587 (GARNOT, GRC) describes a vacuum cleaner having a turbine positioned halfway between the suction nozzle and the reservoir. The distances between the nozzle and the turbine and the turbine and the tank are again important and therefore implies the use of a large suction force. The turbines generally described in the prior art consist of one or more blades positioned on only one of the two faces of the turbine. Reference can be made to US Pat. Nos . 5,340,035, 5,707,017 and 4,426,830. This results in the use of a high rotational speed of the turbine to create an optimal suction force.
En conséquence, la plupart des aspirateurs à feuilles connus à ce jour sont des appareils énergivores et bruyants.As a result, most leaf cleaners known to date are energy-consuming and noisy.
II existe donc un réel besoin pour un nouvel aspirateur à feuilles utilisable dans le domaine agricole ou horticole, permettant d'aspirer efficacement et en grande quantité des feuilles mortes ou tout autre type de débris légers présents sur le sol, et le tout en respectant les nouvelles normes énergétiques et sur le bruit.There is therefore a real need for a new vacuum cleaner with leaves usable in the agricultural or horticultural field, to suck effectively and in large quantities of dead leaves or any other type of light debris on the ground, and while respecting the new energy and noise standards.
Sommaire de l'inventionSummary of the invention
La présente invention a pour but de répondre aux besoins ci-dessus évoqués.The present invention aims to meet the needs mentioned above.
Plus précisément, un premier objet de la présente invention est un aspirateur à feuilles et débris du type comprenant une chambre contenant une turbine conçue et disposée pour aspirer les feuilles et les débris via un bec et les projeter dans un réservoir de stockage, la turbine étant activée par un arbre d'entraînement. Cet aspirateur à feuilles et débris est caractérisé en ce que :More specifically, a first object of the present invention is a vacuum cleaner with leaves and debris of the type comprising a chamber containing a turbine designed and arranged to suck leaves and debris via a spout and project them into a storage tank, the turbine being activated by a drive shaft. This vacuum cleaner leaves and debris is characterized in that:
- la chambre contenant la turbine fait partie intégrante du bec de l'aspirateur;the chamber containing the turbine is an integral part of the nozzle of the vacuum cleaner;
- la turbine comprend deux faces pourvues chacμne d'au moins une pale; etthe turbine comprises two faces each provided with at least one blade; and
- la turbine est positionnée verticalement et perpendiculairement au sein du bec de façon à ce que ses deux faces puissent aspirer les feuilles et les débris dans le bec. L'aspirateur à feuilles selon l'invention peut avantageusement être conçu pour être tracté ou poussé par un véhicule ou manuellement par son utilisateur, un en vue d'aspirer tout débris présent sur le sol, et ce sur une grande surface.- The turbine is positioned vertically and perpendicularly within the beak so that both sides can suck leaves and debris into the beak. The leaf cleaner according to the invention can advantageously be designed to be towed or pushed by a vehicle or manually by its user, one to suck any debris present on the ground, and this over a large area.
Un second objet de la présente invention est l'utilisation de l'aspirateur tel que décrit ci-dessus pour aspirer tout type de débris présent sur un sol.A second object of the present invention is the use of the vacuum cleaner as described above to suck any type of debris present on a floor.
Les avantages de la présente invention sont essentiellement dus à l'utilisation simultanée d'une turbine à double face disposée directement dans le bec d'entrée d'air. Ceci amène à une diminution de la force nécessaire pour aspirer les débris présents sur la surface du sol et par conséquent à une diminution de la vitesse de rotation de la turbine entraînant une diminution de la consommation énergétique de l'aspirateur et du volume sonore occasionné par son utilisation.The advantages of the present invention are essentially due to the simultaneous use of a double-sided turbine disposed directly in the air inlet spout. This leads to a decrease in the force required to suck the debris present on the ground surface and therefore to a decrease in the speed of rotation of the turbine resulting in a decrease in the energy consumption of the vacuum cleaner and the volume of noise caused by its use.
L'invention et ses avantages ressortiront mieux de la description non limitative qui suit d'un mode de réalisation préféré de l'invention, faite en se référant aux dessins annexés.The invention and its advantages will become more apparent from the following nonlimiting description of a preferred embodiment of the invention, with reference to the accompanying drawings.

Description détaillée de l'inventionDetailed description of the invention
L'aspirateur à feuilles (1 ) selon le mode de réalisation préféré illustré sur les Figures 1 a et 1 b, comprend une chambre (3) contenant une turbine (5) conçue et disposée de façon à aspirer les feuilles via un bec (7) et les projeter dans un réservoir de stockage (9).The sheet vacuum cleaner (1) according to the preferred embodiment illustrated in Figures 1a and 1b, comprises a chamber (3) containing a turbine (5) designed and arranged to suck the sheets via a spout (7). ) and project them into a storage tank (9).
Tel qu'on peut mieux le voir sur la Figure 1 b, la turbine (5) est activée et maintenue dans la chambre à l'aide d'un arbre d'entraînement (11 ).As best seen in Figure 1b, the turbine (5) is activated and maintained in the chamber with a drive shaft (11).
Selon l'invention, cet aspirateur à feuilles (1) est caractérisé en ce que :According to the invention, this leaf cleaner (1) is characterized in that:
- le bec (7) comprend directement en son sein la chambre (3) contenant la turbine (5); - la turbine (5) comprend deux faces, chacune des faces étant pourvue d'au- The spout (7) comprises directly within it the chamber (3) containing the turbine (5); the turbine (5) comprises two faces, each of the faces being provided with
, moins une pale (13); et ; minus one blade (13); and ;
- la turbine (5) est positionnée verticalement et perpendiculairement au sein du bec (7) de façon à ce que ses deux faces puissent aspirer les feuilles et les débris dans le bec.- The turbine (5) is positioned vertically and perpendicularly within the spout (7) so that both sides can suck the leaves and debris into the spout.
On comprendra que l'arbre d'entraînement (1 1) est activé en étant relié à un moteur ou à tout autre moyen d'entraînement bien connu dans le domaine de l'invention.It will be understood that the drive shaft (1 1) is activated by being connected to a motor or other drive means well known in the field of the invention.
Selon un mode de réalisation préféré illustré sur les Figures 1 b et 2a, la turbine (5) comprend en fait plusieurs pales (13) positionnées en vis-à-vis sur chacune des faces de la turbine. Les pales sont fixées sur un moyeu central (15) percé en son centre d'un orifice (17) adapté à recevoir l'arbre d'entraînement (11).According to a preferred embodiment illustrated in Figures 1b and 2a, the turbine (5) comprises in fact several blades (13) positioned vis-a-vis on each of the faces of the turbine. The blades are fixed on a central hub (15) pierced at its center with an orifice (17) adapted to receive the drive shaft (11).
Dans le mode de réalisation préféré illustré sur la Figure 2b, les pales (13) de la turbine (5) sont constituées d'une plaque métallique en demi-lune dont les extrémités (19) sont repliées en vis-à-vis afin de former à proprement parler les ailerons des pales (13). Plusieurs pales sont ensuite fixées dos-à-dos par leur partie centrale (20) et côte à côte par leurs ailerons respectifs pour former la turbine (5) à deux faces. Au centre de la turbine est fixé le moyeu central (15).In the preferred embodiment illustrated in FIG. 2b, the blades (13) of the turbine (5) consist of a half-moon metal plate whose ends (19) are folded facing each other in order to to properly train the fins of the blades (13). Several blades are then attached back-to-back by their central portion (20) and side by side by their respective fins to form the turbine (5) with two faces. In the center of the turbine is fixed the central hub (15).
Toujours selon le mode de réalisation préféré illustré sur les Figures 2a et 2b, le moyeu (15) est constitué d'une rondelle (21) dont le centre (22) est percé afin de recevoir un manchon (23) en forme de T1 dont le centre est également percé de façon à recevoir l'arbre d'entraînement (11), tel que cela est représenté sur la Figure 1b. Les faces de la rondelle (21) sont percées de trous (25) permettant de fixer sur le moyeu (15) les pales (13) de la turbine (5).Still according to the preferred embodiment illustrated in Figures 2a and 2b, the hub (15) consists of a washer (21) whose center (22) is drilled to receive a sleeve (23) T-shaped 1 whose center is also drilled to receive the drive shaft (11), as shown in Figure 1b. The faces of the washer (21) are pierced with holes (25) for fixing on the hub (15) the blades (13) of the turbine (5).
Tel qu'on peut mieux l'apprécier sur la Figure 1 b, la turbine (5) est placée de façon verticale dans le bec (7) et est soutenue par son arbre d'entraînement horizontal (11). De plus, le plan contenant le moyeu de la turbine est perpendiculaire au plan contenant le bec.As best appreciated in Figure 1b, the turbine (5) is placed vertically in the spout (7) and is supported by its horizontal drive shaft (11). In addition, the plane containing the hub of the turbine is perpendicular to the plane containing the nozzle.
Tel qu'on peut mieux l'apprécier sur la Figure 3a où la trajectoire de l'air est représentée par des flèches, l'air est aspiré sur toute la largeur de l'extrémité du bec (27) jusqu'aux deux faces de la turbine (5). La distance à parcourir de l'air est fortement diminuée par rapport à ce qu'il existe dans l'art antérieur du fait que :As can best be appreciated in Figure 3a where the air trajectory is represented by arrows, the air is sucked over the entire width of the end of the spout (27) to the two faces of the turbine (5). The distance to be traveled in the air is greatly reduced compared to what exists in the prior art because:
- la turbine (5) est placée à l'intérieur du bec (7) proche du sol, et - cette turbine (5) a une position à la fois verticale et perpendiculaire, le plan contenant la turbine (5) étant perpendiculaire au plan contenant le bec (7).the turbine (5) is placed inside the spout (7) close to the ground, and - This turbine (5) has a position both vertical and perpendicular, the plane containing the turbine (5) being perpendicular to the plane containing the spout (7).
De plus, les deux faces de la turbine sont actives car chacune sont équipées de plusieurs pales (13) permettant d'aspirer l'air.In addition, both faces of the turbine are active because each are equipped with several blades (13) for sucking air.
De par ces propriétés caractéristiques de l'invention, la force nécessaire pour aspirer les feuilles du sol vers la turbine est grandement diminuée. Comme on peut l'apprécier sur la Figure 3b, l'air est ensuite propulsé à la sortie de la chambre (3) directement dans le réservoir de stockage (9), via une canalisation (29).By these characteristic properties of the invention, the force required to suck the soil leaves to the turbine is greatly reduced. As can be appreciated in Figure 3b, the air is then propelled to the outlet of the chamber (3) directly into the storage tank (9) via a pipe (29).
Dans le mode de réalisation préféré illustré sur la Figure 1 b, l'aspirateur à feuilles (1) comprend également une brosse rotative (31 ) installée au sein du bec (7) sous la turbine (5). Cette brosse permet de ratisser tous les débris présents sur le sol et de les envoyer en direction de la turbine. La présence de cette brosse permet là encore de minimiser la force d'aspiration nécessaire au fonctionnement optimal de l'aspirateur. La brosse rotative utilisée peut être une brosse rotative à poils durs ou une brosse rotative à marteaux fous telle que décrite et revendiquée dans la demande en coïnstance N° CA 2.XXX.XXX, déposée le 10 janvier 2006 par la Demanderesse.In the preferred embodiment illustrated in FIG. 1b, the sheet vacuum cleaner (1) also comprises a rotary brush (31) installed within the spout (7) under the turbine (5). This brush makes it possible to rake all the debris present on the ground and to send them towards the turbine. The presence of this brush again makes it possible to minimize the suction force necessary for optimal operation of the vacuum cleaner. The rotary brush used may be a rotary brush with hard bristles or a rotary brush with crazy hammers as described and claimed in the application co-pending No. CA 2.XXX.XXX, filed January 10, 2006 by the Applicant.
Tel que cela est également illustré sur les Figures 1 et 3, l'aspirateur à feuilles selon l'invention peut être monté sur un châssis (33) muni d'au moins une roue de support (35) et d'un moyen de fixation (37) permettant de le fixer à un véhicule de traction. Pour une plus grande stabilité, le châssis peut être muni d'un essieu et de deux ou plusieurs roues.As is also illustrated in FIGS. 1 and 3, the sheet vacuum cleaner according to the invention can be mounted on a frame (33) provided with at least one support wheel (35) and a fixing means (37) for attaching to a traction vehicle. For greater stability, the chassis can be equipped with an axle and two or more wheels.
Selon un deuxième mode de réalisation préféré illustré sur les Figures 4 à 6, l'aspirateur (1 ) selon l'invention est conçu de façon à être plus compact et ainsi pouvoir être déplacé manuellement par son utilisateur. Tel qu'illustré sur ces Figures 4 à 6, cet aspirateur à feuilles compact et monté sur un châssis (39) et comprend deux roues (41) sur le châssis à l'avant de l'aspirateur et deux roues (43) fixées sur le châssis (39) à l'arrière de l'aspirateur.According to a second preferred embodiment illustrated in Figures 4 to 6, the vacuum cleaner (1) according to the invention is designed to be more compact and thus able to be moved manually by its user. As illustrated in FIGS. 4 to 6, this compact leaf vacuum cleaner is mounted on a frame (39) and comprises two wheels (41) on the frame at the front of the vacuum cleaner and two wheels (43) fixed on the frame (39) at the rear of the vacuum cleaner.
L'aspirateur à feuilles compact comprend également au sein de son bec (7) une brosse rotative (31) telle que décrite précédemment (voir Figures 4 à 6).The compact leaf cleaner also comprises within its spout (7) a rotary brush (31) as described above (see Figures 4 to 6).
L'aspirateur illustré sur les Figures 4 à 6 comprend également un socle (45) fixé sur l'un des cotés du bec permettant de recevoir un engin à moteur (47). L'engin à moteur est relié via des moyens d'entraînement à la turbine et/ou la brosse rotative et/ou aux roues pour les faire tourner. Ces moyens d'entraînement peuvent être constitués d'un jeu de poulies (49) et de courroies (voir Figure 4, 5 et 6a).The vacuum cleaner illustrated in Figures 4 to 6 also comprises a base (45) fixed on one side of the spout for receiving a motor vehicle (47). The motor vehicle is connected via drive means to the turbine and / or the rotating brush and / or the wheels to rotate them. These drive means may consist of a set of pulleys (49) and belts (see Figure 4, 5 and 6a).
Finalement, l'aspirateur compact tel qu'illustré sur les Figures 4, 5 et 6b comprend un moyen de déplacement manuel. Préférentiellement, ce moyen de déplacement manuel est constitué de deux bras optionnellement réunis ensemble pour former un U (51 ). Le déplacement de l'aspirateur (1 ) est assisté par l'utilisation de l'engin à moteur (47) relié aux roues arrières (43).Finally, the compact vacuum as illustrated in Figures 4, 5 and 6b includes a manual moving means. Preferably, this manual displacement means consists of two arms optionally joined together to form a U (51). The displacement of the vacuum cleaner (1) is assisted by the use of the motor vehicle (47) connected to the rear wheels (43).
Tel qu'on peut le voir sur les Figures annexées, on comprendra que la distance entre l'extrémité du bec (7) aspirant et la turbine est minimisée, de par l'utilisation d'une turbine (5) comprenant des pales (13) sur ces deux faces et positionnée verticalement au sein du bec et perpendiculairement par rapport au plan du bec, de façon à ce que les deux faces de ,Ia turbine servent à l'aspiration de l'air.As can be seen in the appended figures, it will be understood that the distance between the end of the suction nozzle (7) and the turbine is minimized by the use of a turbine (5) comprising blades (13). ) on both sides and positioned vertically within the nozzle and perpendicular to the plane of the nozzle, so that the two faces of the turbine are used for the suction of air.
On comprendra aussi l'utilisation optionnelle d'une brosse rotative (31) à l'extrémité du bec (27) rend l'aspiration de l'aspirateur à feuilles (1) encore plus efficace. Le fonctionnement optimal de l'aspirateur à feuilles selon l'invention nécessite donc une force d'aspiration inférieure comparativement aux aspirateurs connus dans ce domaine. Tel qu'indiqué précédemment, une force d'aspiration moindre implique une vitesse de rotation de la turbine plus faible et ainsi une diminution de l'énergie nécessaire à son fonctionnement et du bruit.It will also be understood that the optional use of a rotating brush (31) at the end of the spout (27) makes the suction of the leaf cleaner (1) even more efficient. Optimum operation of the sheet vacuum cleaner according to the invention therefore requires a lower suction force compared to vacuum cleaners known in this field. As indicated above, a lower suction force implies a lower rotational speed of the turbine and thus a decrease in the energy required for its operation and noise.
Bien qu'un mode de réalisation préféré de l'invention ait été décrit en détail ci- haut et illustré dans les dessins annexés, l'invention n'est pas limitée à ce seul mode de réalisation. Des changements et modifications pourraient en fait être effectués par une personne versée dans le domaine sans sortir du cadre ni de l'esprit de l'invention. Although a preferred embodiment of the invention has been described in detail above and illustrated in the accompanying drawings, the invention is not limited to this single embodiment. Changes and modifications could in fact be made by someone versed in the field without departing from the scope or spirit of the invention.
