- the user 5 can thus vary the acceleration, the speed or the orientation of the propellers 31 a and 31 b in order to place the cutting / clearing tool 20 at the height he wishes.
- the user 5 then starts the pruning / brushcutting tool 20 using the piloting means 60 provided for this purpose, and begins pruning.

- security means will be provided to prevent the user 5 from letting go of the grip handle 10. He will, for example, have to permanently press on one or more organ (s) (buttons, handles), as on many tools of this type (mower, hedge trimmer) so that any loosening of the members described above will immediately stop the pruning / brush cutting tool 20 and the motors 35a and 35b of the propellers 31 a and 31 b (from preferably gradually to avoid an excessively brutal shock when the grip handle 10 falls to the ground).
- organ s
- These means for ensuring, in use, its handling in an uninterrupted manner by a user will in the present case be materialized by the control means 60 of the pruning / brushcutting tool 10 and / or by the control means 50 of the propellers. 31 a and 31 b.

- the assembly 1 comprises, in place of the pruning tool, a light projector 24 orientable on an articulated system 25 such as a ball joint. Again, the operation of this device is similar to that described above in order to relieve the user 5 of the maximum weight to be carried.
- the user 5 can place the proximal end 11 of the grip handle 10 in a robust and sufficiently heavy support 200 which is placed on the ground at a chosen location.
- the proximal end 1 1 is introduced into an orifice of an articulated connection 210 of the ball type which is integral with the support 200.
- the user 5 (not shown) can direct the grip handle 10 at a distance (inclination , rotation using the ball 210) and therefore the projector 24 to switch on remote areas which are difficult to access.

Description
Ensemble comportant un manche de préhension pour un outil de travail et des moyens de lévitation aérodynamique motorisés. Assembly comprising a grip handle for a working tool and motorized aerodynamic levitation means.
DOMAINE TECHNIQUE DE L’INVENTION TECHNICAL FIELD OF THE INVENTION
La présente invention concerne un ensemble comprenant au moins un manche de préhension présentant une extrémité proximale pour sa prise en main par un utilisateur et une extrémité distale supportant un outil de travail actionnable à distance par ledit utilisateur. The present invention relates to an assembly comprising at least one grip handle having a proximal end for its grip by a user and a distal end supporting a working tool which can be actuated remotely by said user.
ÉTAT DE LA TECHNIQUE STATE OF THE ART
A l’heure actuelle, dans de nombreux domaines techniques, il est courant d’utiliser une perche ou un manche supportant un outil de travail à son extrémité distale (NB : extrémité la plus éloignée d’un utilisateur), permettant ainsi à l’utilisateur de travailler à distance. At present, in many technical fields, it is common to use a pole or a handle supporting a working tool at its distal end (NB: end furthest from a user), thus allowing the user to work remotely.
On peut citer par exemple les dispositifs d’élagage, de pulvérisation de produit fluide (traitement de charpente ou de plantation, peinture, nettoyage de toiture ou de véhicule terrestre, nautique ou aéronautique), de prise de vue et/ou de son (caméra/appareil photo/microphone), d’éclairage, de support d’appareil tel qu’une antenne ou un haut-parleur, etc. Mention may be made, for example, of pruning devices, spraying of fluid product (frame or planting treatment, painting, cleaning of roofs or land, nautical or aeronautical vehicles), shooting and / or sound (camera / camera / microphone), lighting, device mount such as an antenna or speaker, etc.
Tous ces systèmes permettent à un utilisateur de faire fonctionner un outil ou un appareil à une distance plus ou moins importante du point où il se trouve car il ne peut en général pas y accéder pour différentes raisons (trop haut, trop risqué, trop difficile d’accès). All these systems allow a user to operate a tool or an appliance at a greater or lesser distance from the point where it is located because he generally cannot access it for various reasons (too high, too risky, too difficult to 'access).
Dans le domaine particulier de l’élagage pour tailler/débroussailler la végétation (arbustes, arbres), les dispositifs de type connu se composent essentiellement d’un outil de taille/débroussaillage, par exemple une tronçonneuse à chaîne, un taille-haie à lames ou un sécateur à mâchoires, tenu manuellement par un utilisateur. Ces dispositifs donnent a priori entière satisfaction pour des opérations se tenant « à hauteur d’homme », l’utilisateur prenant appui sur le sol, à proximité de la végétation à élaguer. In the particular field of pruning for pruning / clearing vegetation (shrubs, trees), the devices of known type essentially consist of a pruning / clearing tool, for example a chain saw, a hedge trimmer with blades. or a jaw pruner, held manually by a user. These devices are a priori entirely satisfactory for operations standing "at breast height", the user resting on the ground, close to the vegetation to be pruned.
Cependant, lorsqu’il est nécessaire de tailler des haies d’arbustes ou des arbres à une hauteur importante, par exemple au-delà de 2 m, ces dispositifs ne sont pas adaptés. Il existe alors globalement trois solutions à ce problème. However, when it is necessary to trim hedges of shrubs or trees at a significant height, for example beyond 2 m, these devices are not suitable. There are then generally three solutions to this problem.
La première consiste à monter dans les arbres avec l’outil de taille/débroussaillage. Or, les élagueurs pratiquant cette technique prennent énormément de risques de blessures par chute, par chute des branches The first is to climb trees with the pruning / clearing tool. However, pruners practicing this technique take a huge risk of injury from falling, from falling branches
FEUILLE DE REMPLACEMENT (RÈGLE 26)
coupées ou par chute de l’outil en fonctionnement. Ce travail à hauts risques est également très coûteux en assurance et en temps. SUBSTITUTE SHEET (RULE 26) cut or dropped from the tool during operation. This high-risk work is also very costly in terms of insurance and time.
La deuxième solution, extrêmement simple mais limitée, consiste à utiliser un moyen pour que l’utilisateur lui-même soit placé plus en hauteur. Pour cela, il peut utiliser un tabouret, un escabeau, une échelle, voire un dispositif motorisé de type nacelle ou camion spécialisé de déboisement. The second solution, which is extremely simple but limited, consists in using a means so that the user himself is placed higher. For this, he can use a stool, a stepladder, a ladder, or even a motorized device of the nacelle or specialized deforestation truck type.
Cependant, ces solutions sont soit potentiellement dangereuses pour les premières, avec un risque que l’utilisateur se blesse plus ou moins gravement en chutant avec l’outil, soit onéreuses et/ou complexes à mettre en oeuvre pour la seconde (problème d’accessibilité du porte-nacelle ou du camion, impossibilité pour le porte-nacelle ou le camion de se déplacer facilement si le terrain est accidenté par exemple). However, these solutions are either potentially dangerous for the first, with a risk that the user will be more or less seriously injured by falling with the tool, or expensive and / or complex to implement for the second (accessibility problem from the basket or truck, impossibility for the basket or the truck to move easily if the terrain is rough, for example).
Une troisième solution connue consiste alors à placer l’outil de taille/débroussaillage au bout d’une tige pour l’éloigner de l’utilisateur et atteindre des branches plus hautes et/ou des endroits plus difficiles d’accès (végétation épaisse et dense par exemple). A third known solution then consists in placing the pruning / clearing tool at the end of a rod to move it away from the user and reach higher branches and / or places more difficult to access (thick and dense vegetation for example).
On connaît par exemple les solutions décrites dans les brevets FR2455427, FR2610167, FR2621779, FR2671689, FR270841 1 , FR2826234 et FR2953683 concernant une cisaille manuelle ou électrique, dans les brevets EP3058807, US5884403, US2005086813, US2006005673, US2006048397 et US4207675 concernant les tronçonneuses et dans les brevets EP3213627, et US5787590 concernant les tailles-haie. We know, for example, the solutions described in patents FR2455427, FR2610167, FR2621779, FR2671689, FR270841 1, FR2826234 and FR2953683 concerning a manual or electric shears, in patents EP3058807, US5884403, US2005086813, US2006005673, US2006048757 and US4607757 and patents EP3213627, and US5787590 concerning hedge trimmers.
Ces dispositifs de report de l’outil au bout d’un bras permettent en effet à l’utilisateur de prendre une position stable sur le sol. Mais en contrepartie, l’utilisateur doit redoubler d’effort pour effectuer la taille des arbustes ou arbres. En effet, l’élagage s’effectue à distance de la zone où l’utilisateur tient la tige, c’est à dire entre son bassin et ses épaules, et plus probablement au niveau de son abdomen. Or, plus la zone de taille est éloignée de l’utilisateur, notamment quand il s’agit d’élagage en hauteur, plus le porte-à-faux de l’outil est important, plus les efforts à fournir peuvent être difficile à supporter. These devices for transferring the tool to the end of an arm allow the user to take a stable position on the ground. But in return, the user must redouble their efforts to prune the shrubs or trees. Pruning is done at a distance from the area where the user holds the stem, ie between his pelvis and his shoulders, and more probably at the level of his abdomen. However, the further the pruning area is from the user, especially when it comes to pruning in height, the greater the overhang of the tool, the more the efforts to be made can be difficult to bear .
Ainsi, toutes ces solutions présentent globalement les mêmes inconvénients, à savoir un poids particulièrement élevé qui rend l’élagage fatiguant voire dangereux pour l’utilisateur à cause du porte à faux important,
un élagage potentiellement inefficace (manque de précision) du fait de la difficulté de manipuler la charge constitué par l’outil disposé au bout de la tige, et une accessibilité des branches à élaguer réduite à une hauteur relativement faible pour les raisons évoquées précédemment. Thus, all of these solutions generally have the same drawbacks, namely a particularly high weight which makes pruning tiresome or even dangerous for the user because of the large overhang, potentially ineffective pruning (lack of precision) due to the difficulty of handling the load constituted by the tool placed at the end of the rod, and accessibility of the branches to be pruned reduced to a relatively low height for the reasons mentioned above.
De la même façon, dans le domaine du traitement des toitures (tuiles, charpentes), il est connu d’utiliser des pulvérisateurs mais ceux-ci ne présentent qu’une courte distance d’utilisation. Or, il est souvent nécessaire d’accéder à des endroits particulièrement hauts donc et potentiellement dangereux. Similarly, in the field of roofing treatment (tiles, frameworks), it is known to use sprayers but these only have a short distance of use. However, it is often necessary to access particularly high and therefore potentially dangerous places.
Le même problème se pose dans le domaine de la peinture ou encore dans le nettoyage de véhicules automobiles (camions), nautiques (paquebots, cargos) ou aéronautiques (avions, hélicoptères). Là encore, ces dispositifs sont limités notamment en distance et/ou en poids supporté. The same problem arises in the field of painting or in the cleaning of motor vehicles (trucks), nautical vehicles (ocean liners, cargo ships) or aeronautics (planes, helicopters). Again, these devices are limited in particular in distance and / or weight supported.
Dans le milieu de la prise de vue et/ou de son, on connaît également des solutions faisant appel à des perches utilisées par exemple dans les concerts (en plein air ou dans de grandes salles de spectacle notamment) ou sur un tournage, afin de pouvoir déplacer une caméra et/ou un micro loin d’un opérateur, en survolant par exemple une foule de spectateurs ou des acteurs. Mais ces systèmes sont extrêmement coûteux, complexes à concevoir et compliqués à manipuler. In the field of shooting and / or sound, solutions are also known which use poles used for example in concerts (in the open air or in large concert halls in particular) or on a set, in order to ability to move a camera and / or microphone away from an operator, for example by flying over a crowd of spectators or actors. But these systems are extremely expensive, complex to design and complicated to handle.
Par conséquent, les solutions de l’art antérieur ne sont donc pas optimisées, leur utilisation est donc restreinte et elles manquent potentiellement d’efficacité. Consequently, the solutions of the prior art are therefore not optimized, their use is therefore restricted and they potentially lack efficiency.

La présente invention a pour objectif de répondre au moins en partie aux limitations de l’art antérieur précédemment évoqué. The present invention aims to respond at least in part to the limitations of the prior art mentioned above.
A cet effet, l’invention se rapporte à un ensemble comprenant au moins un manche de préhension s’étendant selon une direction longitudinale et présentant une extrémité proximale pour sa prise en main par un utilisateur et une extrémité distale supportant un outil de travail actionnable à distance par ledit utilisateur au niveau de l’extrémité proximale, caractérisé en ce que le manche de préhension est pourvu de moyens de lévitation aérodynamique motorisés.
De cette façon, le poids de l’outil est en partie supporté par les moyens de lévitation, typiquement au moins 50%, sans pour autant que l’utilisateur lâche le manche de préhension. Le porte-à-faux est également notablement réduit voire totalement annulé, ce qui facilite énormément le travail. L’utilisateur peut donc non seulement être plus précis dans ces gestes, car il a moins de charge à soulever, mais il peut également travailler pendant une période plus longue du fait de ce soulagement d’une grande partie de la charge habituellement soulevée. Enfin, l’utilisateur peut utiliser des manches de préhension bien plus longs (et potentiellement plus lourds) et/ou des outils plus massifs, et donc travailler à des distance bien plus importantes que dans l’art antérieur. To this end, the invention relates to an assembly comprising at least one grip handle extending in a longitudinal direction and having a proximal end for its grip by a user and a distal end supporting a working tool that can be actuated distance by said user at the proximal end, characterized in that the grip handle is provided with motorized aerodynamic levitation means. In this way, the weight of the tool is partly supported by the levitation means, typically at least 50%, without the user letting go of the grip handle. The overhang is also significantly reduced or even completely canceled, which greatly facilitates the work. The user can therefore not only be more precise in these gestures, since he has less load to lift, but he can also work for a longer period because of this relief of a large part of the load usually lifted. Finally, the user can use much longer (and potentially heavier) gripping handles and / or more massive tools, and therefore work at much greater distances than in the prior art.

Les figures 1 à 4 représentent un dispositif d’élagage 1 pour tailler/débroussailler la végétation, en particulier des branches d’arbres ou d’arbustes éloignées d’un élagueur 5, situées par exemple en hauteur par rapport à ce dernier. Figures 1 to 4 show a pruning device 1 for pruning / clearing vegetation, in particular branches of trees or shrubs distant from a pruner 5, located for example in height relative to the latter.
On entend par « éloignées » ou « situées en hauteur » le fait que l’utilisateur 5 n’a pas directement accès à la végétation qu’il doit élaguer mais qu’il doive utiliser, comme on va le décrire ci-après, un moyen lui permettant de tailler/débroussailler de la végétation située à distance de lui, par exemple des branches situées en hauteur à plus de 2 m au dessus du sol, jusqu’à plusieurs dizaines de mètres, ou loin de l’utilisateur en raison d’une végétation dense et épaisse. By “distant” or “located in height” is meant the fact that the user 5 does not have direct access to the vegetation which he must prune but that he must use, as will be described below, a means enabling it to trim / clear vegetation located at a distance from it, for example branches located in height more than 2 m above the ground, up to several tens of meters, or far from the user due to '' dense and thick vegetation.
Ce dispositif d’élagage 1 comporte typiquement un manche de préhension 10 s’étendant selon une direction longitudinale et présentant une
extrémité proximale 1 1 pourvue d’une part d’une zone de préhension 12 pour un utilisateur 5 et d’autre part d’une extrémité distale 13 supportant un outil de taille/débroussaillage 20 tel qu’une lame mobile de taille-haie, des mâchoires de cisaille ou une chaîne de tronçonneuse. This pruning device 1 typically comprises a gripping handle 10 extending in a longitudinal direction and having a proximal end 1 1 provided on the one hand with a gripping zone 12 for a user 5 and on the other hand with a distal end 13 supporting a pruning / clearing tool 20 such as a movable hedge trimmer blade, shear jaws or a chainsaw chain.
Le manche de préhension 10 comporte également, proche de l’outil de taille/débroussaillage 20, des moyens 30 de lévitation aéronautique motorisés faisant l’objet de la présente invention. The gripping handle 10 also comprises, close to the pruning / brushcutting tool 20, motorized aeronautical levitation means 30 which are the subject of the present invention.
Ces moyens de lévitation 30 prennent typiquement la forme d’au moins une hélice 31 , et de préférence au moins deux hélices 31 a et 31 b, montées respectivement en rotation sur des axes 32a et 32b qui se dressent perpendiculairement audit manche de préhension 10 (voir figure 4 par exemple). Les axes des 32a et 32b des hélices 31 a et 32b sont mis en rotation à l’aide de moteurs respectifs 35a et 35b. These levitation means 30 typically take the form of at least one propeller 31, and preferably at least two propellers 31 a and 31 b, mounted respectively in rotation on axes 32a and 32b which stand perpendicular to said grip handle 10 ( see figure 4 for example). The axes of 32a and 32b of the propellers 31a and 32b are rotated using respective motors 35a and 35b.
Comme cela est également visible sur les figures 1 à 4, les hélices 31 a et 31 b sont pourvues respectivement de premiers carénages de proximité 33a et 33b les entourant chacune sur toute leur circonférence et permettant d’améliorer leur portance. As is also visible in FIGS. 1 to 4, the propellers 31 a and 31 b are respectively provided with first proximity fairings 33 a and 33 b each surrounding them around their entire circumference and making it possible to improve their lift.
L’hélice 31 a disposées la plus proche de l’outil de taille/débroussaillage 20 comporte également un second carénage de protection 34a destiné à éviter que l’hélice 31 a se prennent dans les branches à tailler/taillées ou dans les feuilles. Ce second carénage 34a entoure localement le premier carénage 33a et prend la forme d’une portion annulaire décrivant par exemple un quart de cercle et comportant une structure ajourée de type grillage. The propeller 31a disposed closest to the pruning / brushcutting tool 20 also includes a second protective fairing 34a intended to prevent the propeller 31a from getting caught in the branches to be pruned / pruned or in the leaves. This second fairing 34a locally surrounds the first fairing 33a and takes the form of an annular portion describing for example a quarter of a circle and comprising an openwork structure of the mesh type.
Le manche de préhension 10 comporte, au voisinage de son extrémité proximale 1 1 , des moyens 50 de commande d’au moins un paramètre de rotation de chaque hélice 31 a et 31 b parmi sa vitesse, son accélération et son inclinaison. Ces moyens de commande 50 peuvent prendre la forme de bouton, levier, poignée rotative « de gaz » ou autre. The grip handle 10 comprises, in the vicinity of its proximal end 11, means 50 for controlling at least one parameter of rotation of each propeller 31 a and 31 b among its speed, its acceleration and its inclination. These control means 50 can take the form of a button, lever, rotary “gas” handle or the like.
Les moyens de commande 50 de chaque hélice 31 a et 31 b sont avantageusement pourvus d’une assistance électronique au démarrage, décollage et atterrissage pour faciliter le pilotage du dispositif d’élagage 1.
Le manche de préhension 10 comporte également, proche de son extrémité proximale 1 1 , des moyens de pilotage 60 de l’outil de taille/débroussaillage 10. Ces moyens de pilotage 60 sont indépendants des moyens de commande 50 des hélices 31 a et 31 b et peuvent là encore prendre différentes formes : levier, bouton, poignée rotative, etc. The control means 50 of each propeller 31 a and 31 b are advantageously provided with electronic assistance at start-up, take-off and landing to facilitate piloting of the pruning device 1. The gripping handle 10 also comprises, near its proximal end 11, control means 60 of the pruning / brushcutting tool 10. These control means 60 are independent of the control means 50 of the propellers 31 a and 31 b and can again take different forms: lever, button, rotary handle, etc.
Le manche de préhension 10 est pourvu, au voisinage de l’extrémité proximale 1 1 , d’une barre transversale de direction 70 qui se dresse latéralement par rapport audit manche. Cette barre transversale 70, mesurant par exemple quelques dizaines de centimètres, permet à l’utilisateur 5 d’une part d’améliorer la préhension du dispositif d’élagage 1 en répartissant au mieux la charge soulevée, de garantir une meilleure stabilisation du manche de préhension 10 et de faciliter le pilotage du dispositif d’élagage 1 comme cela sera décrit ultérieurement. The grip handle 10 is provided, in the vicinity of the proximal end 11, with a transverse direction bar 70 which stands laterally with respect to said handle. This transverse bar 70, measuring for example a few tens of centimeters, allows the user 5 on the one hand to improve the grip of the pruning device 1 by distributing the lifted load as well as possible, to guarantee better stabilization of the handle of gripping 10 and to facilitate the control of the pruning device 1 as will be described later.
En variante, comme illustré, les moyens de pilotage 60 peuvent être portés par la barre transversale 70. As a variant, as illustrated, the control means 60 can be carried by the transverse bar 70.
Avantageusement, l’outil de taille/débroussaillage 20 est articulé par rapport au manche de préhension 10 selon au moins un axe de rotation perpendiculaire audit manche de préhension 10 et/ou dans le prolongement de ce dernier. Ces articulations peuvent être obtenues à l’aide de pivots de rotation motorisés s’étendant perpendiculairement au manche de préhension 10, ou d’une rotule. Ils permettent de régler à distance l’inclinaison de l’outil de taille/débroussaillage 20 pour s’adapter aux positions, orientations et formes respectives des branches à couper. Advantageously, the pruning / clearing tool 20 is articulated relative to the gripping handle 10 along at least one axis of rotation perpendicular to said gripping handle 10 and / or in the extension of the latter. These joints can be obtained using motorized rotation pivots extending perpendicular to the grip handle 10, or a ball joint. They allow the inclination of the pruning / brushcutting tool 20 to be adjusted remotely to adapt to the positions, orientations and respective shapes of the branches to be cut.
L’outil de taille/débroussaillage 20 ainsi que les moteurs de lévitation 35a et 35b dont sont munies les hélices 31 a et 31 b sont alimentés par une source d’énergie électrique (non représentée). Il pourra typiquement s’agir de batteries de forte capacité (Li-lon) portées par l’utilisateur 5, par exemple dans un sac à dos (non illustré), et reliées de manière amovibles aux moteurs 35a et 35b des hélices 31 a et 31 b et à l’outil de taille/débroussaillage 20 par l’intermédiaire de câbles (non représentés) guidés par le manche de préhension 10. The pruning / brushcutting tool 20 as well as the levitation motors 35a and 35b with which the propellers 31a and 31b are provided are powered by a source of electrical energy (not shown). It can typically be high capacity batteries (Li-lon) carried by the user 5, for example in a backpack (not shown), and detachably connected to the motors 35a and 35b of the propellers 31 a and 31b and to the pruning / brushcutting tool 20 via cables (not shown) guided by the gripping handle 10.
Afin de pouvoir avoir accès à des branches notablement éloignées de l’utilisateur 5, le manche de préhension 10 est télescopique et comporte par
exemple plusieurs tronçons emboîtables les uns dans les autres et démontables. Avantageusement, pour des questions de rapport poids/résistance, le manche de préhension 10 sera majoritairement constitué de fibre de carbone et/ou de verre (pour le côté isolant électriquement en cas de contact avec des câbles électriques). Il mesurera entre 2m (un tronçon) et plusieurs dizaines de mètres, par exemple 20 mètres (10 tronçons). Les tronçons du manche de préhension 10 peuvent être de section carré afin d’éviter le problème de rotation des tronçons les uns par rapport aux autres. In order to be able to have access to branches which are significantly distant from the user 5, the grip handle 10 is telescopic and comprises example several sections which fit together and which can be dismantled. Advantageously, for questions of weight / resistance ratio, the grip handle 10 will mainly consist of carbon fiber and / or glass (for the electrically insulating side in the event of contact with electric cables). It will measure between 2m (a section) and several tens of meters, for example 20 meters (10 sections). The sections of the gripping handle 10 may be of square section in order to avoid the problem of rotation of the sections relative to each other.
Le dispositif d’élagage 1 est équipé d’un amortisseur de choc 80 situé à proximité de l’outil de taille/débroussaillage 20, par exemple sous le second carénage 34a, ou directement fixé à l’outil de taille/débroussaillage 20. Cela permet d’éviter d’abimer l’outil de taille/débroussaillage 20 lorsque les moteurs 35a et 35b des hélices 31 a et 31 b sont stoppés et que le poids de l’ensemble du dispositif d’élagage 1. The pruning device 1 is equipped with a shock absorber 80 located near the pruning / brushcutting tool 20, for example under the second fairing 34a, or directly attached to the pruning / brushcutting tool 20. This avoids damaging the pruning / brushcutting tool 20 when the motors 35a and 35b of the propellers 31 a and 31 b are stopped and the weight of the entire pruning device 1.
Comme l’utilisateur 5 est souvent placé relativement loin de l’outil de taille/débroussaillage 20, ou qu’il lui est quasiment impossible de le voir à cause de la densité de la végétation, il est prévu de munir le dispositif d’élagage 1 d’une caméra 90 disposée proche de l’outil de taille/débroussaillage 20, et accessoirement d’un écran de contrôle 100 disposé au voisinage de l’extrémité proximale 1 1 du manche de préhension 10, par exemple sur la barre transversale 70. As the user 5 is often placed relatively far from the pruning / clearing tool 20, or it is almost impossible for him to see it because of the density of the vegetation, provision is made to provide the pruning device 1 of a camera 90 placed close to the pruning / clearing tool 20, and incidentally of a control screen 100 placed in the vicinity of the proximal end 11 of the grip handle 10, for example on the crossbar 70 .
Selon un mode de réalisation illustré par la figure 5, les moteurs 35a et 35b des axes de rotation 32a et 32b des hélices 31 a et 31 b sont montés respectivement au bout de bras 41 a et 41 b tournant autour de pivots 42a et 42b liés. Avantageusement les bras 41 a et 42b pivotent sur 90° de manière à éloigner latéralement les hélices 31 a et 31 b du manche de préhension 10, les deux bras 41 a et 42b étant alors de préférence orientés du même angle (dans le sens des aiguilles d’une montre pour l’un et dans le sens antihoraire pour l’autre) afin de ne pas gêner la stabilisation latérale du manche de préhension 10. According to an embodiment illustrated in FIG. 5, the motors 35a and 35b of the axes of rotation 32a and 32b of the propellers 31a and 31b are mounted respectively at the end of arms 41a and 41b rotating around pivots 42a and 42b linked . Advantageously, the arms 41 a and 42 b pivot through 90 ° so as to move the propellers 31 a and 31 b laterally from the grip handle 10, the two arms 41 a and 42 b then preferably being oriented at the same angle (in the direction of the needles one for one and counterclockwise for the other) so as not to hinder the lateral stabilization of the grip handle 10.
Le fonctionnement du dispositif d’élagage 1 conforme à la présentation est le suivant :
Une fois positionné dans la zone à élaguer, avec les batteries chargées logées dans le sac à dos et branchées au câble d’alimentation des moteurs de lévitation des hélices et de l’outil de taille/débroussaillage 20, l’utilisateur 5 saisi alors le manche de préhension 10 au niveau de la zone de préhension 12 et met en route les hélices 31 a et 31 b pour le décollage du dispositif d’élagage 1. Il peut alors soulager le poids du dispositif d’élagage 1 , en particulier de l’outil de taille/débroussaillage 20 situé à son extrémité distale 13 grâce à la lévitation aérodynamique procurée par les hélices 31 a et 31 b. The operation of the pruning device 1 in accordance with the presentation is as follows: Once positioned in the area to be pruned, with the charged batteries housed in the backpack and connected to the power cable of the propeller levitation motors and of the pruning / clearing tool 20, the user 5 then grasps the gripping handle 10 at the gripping zone 12 and starts the propellers 31 a and 31 b for the take-off of the pruning device 1. It can then relieve the weight of the pruning device 1, in particular the 'pruning / brushcutting tool 20 located at its distal end 13 thanks to the aerodynamic levitation provided by the propellers 31 a and 31 b.
En manipulant les moyens de commande 50 des moteurs 35a et 35b des hélices 31 a et 31 b, l’utilisateur 5 peut faire se soulever plus ou moins haut le manche de préhension 10 et l’incliner dans l’air au-dessus de lui, ou le maintenir en altitude, toujours en le tenant manuellement au niveau de la zone de préhension 12, de manière à atteindre les branches plus ou moins éloignés. En fonction de la vitesse des hélices 31 a et 31 b, l’inclinaison pourra varier de 0° à environ 70° par rapport au plan du sol sur lequel se trouve l’utilisateur 5, 70° étant la position maximale au-delà de laquelle l’élagage peut devenir dangereux car il s’agit d’une limite de sécurité imposée. By manipulating the control means 50 of the motors 35a and 35b of the propellers 31 a and 31 b, the user 5 can raise the handle 10 more or less high and tilt it in the air above him , or maintain it in altitude, still holding it manually at the level of the gripping zone 12, so as to reach the more or less distant branches. Depending on the speed of the propellers 31 a and 31 b, the inclination may vary from 0 ° to around 70 ° relative to the ground plane on which the user is located 5, 70 ° being the maximum position beyond which pruning can become dangerous because it is a safety limit imposed.
L’utilisateur 5 peut ainsi faire varier l’accélération, la vitesse ou l’orientation des hélices 31 a et 31 b pour placer l’outil de taille/débroussaillage 20 à la hauteur qu’il souhaite. Une fois l’altitude atteinte, l’utilisateur 5 met alors en route l’outil de taille/débroussaillage 20 à l’aide des moyens de pilotage 60 prévus à cet effet, et commencer l’élagage. On notera que le second carénage 34a permettra d’éviter que des branches ou des feuilles se coincent dans les hélices 31 a et 31 b (principalement l’hélice 31 a celle la plus proche de l’outil de taille/ débroussaillage 20). The user 5 can thus vary the acceleration, the speed or the orientation of the propellers 31 a and 31 b in order to place the cutting / clearing tool 20 at the height he wishes. Once the altitude is reached, the user 5 then starts the pruning / brushcutting tool 20 using the piloting means 60 provided for this purpose, and begins pruning. Note that the second fairing 34a will prevent branches or leaves from getting stuck in the propellers 31 a and 31 b (mainly the propeller 31 to the one closest to the pruning / brushcutting tool 20).
Lorsque l’utilisateur 5 souhaite aller vers la gauche, et s’il tient la barre transversale 70 de la main gauche (a priori pour un droitier), il fait pivoter ladite barre 70 légèrement vers le bas, en gardant sensiblement la même inclinaison du manche de préhension 10 par rapport à l’horizontale, ce qui a pour effet d’orienter les axes respectif de rotation 32a et 32b des hélices 31 a et 31 b vers la gauche, ce qui provoque le déplacement du dispositif d’élagage 1 vers la gauche. S’il veut aller vers la droite, il exécute la manoeuvre inverse et relève légèrement la barre transversale 70.
La caméra 90 permet à l’utilisateur 5 de visualiser des zones loin de lui et d’adapter au mieux la force de lévitation des hélices 31 a et 31 b pour amener l’outil de taille/débroussaillage 20 au plus proche des branches à couper. L’utilisateur 5 pourra vérifier en temps réel son approche à l’aide de l’écran de contrôle 100 fixé à la barre transversale de direction 70. When the user 5 wishes to go to the left, and if he holds the transverse bar 70 with his left hand (a priori for a right-handed person), he pivots said bar 70 slightly downward, keeping substantially the same inclination of the gripping handle 10 relative to the horizontal, which has the effect of orienting the respective axes of rotation 32a and 32b of the propellers 31 a and 31 b to the left, which causes the pruning device 1 to move towards left. If he wants to go to the right, he performs the reverse maneuver and slightly raises the crossbar 70. The camera 90 allows the user 5 to view areas far from him and to best adapt the levitation force of the propellers 31 a and 31 b to bring the pruning / brushcutting tool 20 as close as possible to the branches to be cut. . The user 5 will be able to check his approach in real time using the control screen 100 fixed to the transverse steering bar 70.
Une assistance électronique est prévue pour faciliter les opérations de décollage et atterrissage du manche de préhension 10. On peut par exemple prévoir qu’un appui sur un bouton provoque le démarrage progressif des hélices 31 a et 31 b (simultanément ou l’une après l’autre) et la stabilisation du manche de préhension 10. Electronic assistance is provided to facilitate take-off and landing of the gripping handle 10. It can for example be provided that pressing a button causes the propellers 31 a and 31 b to start gradually (simultaneously or one after the 'other) and stabilization of the grip handle 10.
Bien entendu, des moyens de sécurité seront prévus pour empêcher à l’utilisateur 5 de lâcher le manche de préhension 10. Il devra par exemple appuyer en permanence sur un ou plusieurs organe(s) (boutons, poignées), comme sur de nombreux outils de ce type (tondeuse, taille-haie) de sorte que tout relâchement des organes décrits ci-dessus provoquera l’arrêt immédiat de l’outil de taille/débroussaillage 20 et des moteurs 35a et 35b des hélices 31 a et 31 b (de préférence progressivement pour éviter un choc trop brutal lors de la retombée du manche de préhension 10 au sol). Ces moyens pour assurer, en utilisation, sa prise en main de manière ininterrompue par un utilisateur seront dans le cas présent matérialisés par les moyens de pilotage 60 de l’outil de taille/débroussaillage 10 et/ou par les moyens de commande 50 des hélices 31 a et 31 b. Of course, security means will be provided to prevent the user 5 from letting go of the grip handle 10. He will, for example, have to permanently press on one or more organ (s) (buttons, handles), as on many tools of this type (mower, hedge trimmer) so that any loosening of the members described above will immediately stop the pruning / brush cutting tool 20 and the motors 35a and 35b of the propellers 31 a and 31 b (from preferably gradually to avoid an excessively brutal shock when the grip handle 10 falls to the ground). These means for ensuring, in use, its handling in an uninterrupted manner by a user will in the present case be materialized by the control means 60 of the pruning / brushcutting tool 10 and / or by the control means 50 of the propellers. 31 a and 31 b.
A cet effet, l’amortisseur de choc 80 permettra d’éviter d’abimer ou de détruire l’outil de taille/débroussaillage 20. To this end, the shock absorber 80 will make it possible to avoid damaging or destroying the pruning / brushcutting tool 20.
Selon un autre mode de réalisation illustré par la figure 6, l’ensemble 1 comprend les mêmes éléments que précédemment à ceci près que l’outil d’élagage 20 est remplacé par un appareil 21 de projection de fluide muni d’un réservoir 22 et d’une buse 23, tel qu’un pulvérisateur pour le traitement de la végétation, de poutres de charpente ou de tuiles de toiture. Dans un autre mode de réalisation, le réservoir peut être placé au sol et relié à la buse via un tuyau qui transite par la barre de préhension According to another embodiment illustrated by FIG. 6, the assembly 1 comprises the same elements as previously except that the pruning tool 20 is replaced by an apparatus 21 for spraying fluid provided with a reservoir 22 and of a nozzle 23, such as a sprayer for the treatment of vegetation, of structural beams or roof tiles. In another embodiment, the reservoir can be placed on the ground and connected to the nozzle via a pipe which passes through the grip bar
Dans tous les cas évoqués précédemment de manière non limitative, le pulvérisateur 21 peut comporter une pompe de type « airless » portée par
l’utilisateur 5 (ou être posée au sol) et reliée au réservoir 22 à l’aide d’une durite (non représentée) guidée par le manche 10. In all the cases mentioned above in a nonlimiting manner, the sprayer 21 may include an “airless” type pump carried by the user 5 (or be placed on the ground) and connected to the reservoir 22 using a hose (not shown) guided by the handle 10.
L’utilisation de cet ensemble 1 dit « de pulvérisation » est identique à celle de l’ensemble d’élagage décrit précédemment en relation avec les figures 1 à 4, à la différence qu’il s’agit dans le cas présent de pulvériser un liquide dans des zones bien définies afin par exemple d’exterminer des nuisibles (végétation, charpente) ou de la mousse (tuiles). The use of this assembly 1 called “spraying” is identical to that of the pruning assembly described above in relation to FIGS. 1 to 4, with the difference that it is a question here of spraying a liquid in well defined areas in order for example to exterminate pests (vegetation, frame) or moss (tiles).
Selon un autre mode de réalisation illustré par la figure 7, l’ensemble 1 comporte, à la place de l’outil d’élagage, un projecteur lumineux 24 orientable sur un système articulé 25 tel qu’une rotule. Là encore, le fonctionnement de cet appareil est similaire à celui décrit précédemment à fin de délester l’utilisateur 5 du maximum de poids à porter. According to another embodiment illustrated in Figure 7, the assembly 1 comprises, in place of the pruning tool, a light projector 24 orientable on an articulated system 25 such as a ball joint. Again, the operation of this device is similar to that described above in order to relieve the user 5 of the maximum weight to be carried.
Par ailleurs, une fois les moteurs 35a et 35b amorcés et l’ensemble 1 bien stabilisé avec un angle d’inclinaison avec le sol déterminé (70° dans le cas présent), l’utilisateur 5 peut placer l’extrémité proximale 1 1 du manche de préhension 10 dans un support 200 robuste et suffisamment lourd qui est posé sur le sol à un endroit choisi. Avantageusement, l’extrémité proximale 1 1 est introduite dans un orifice d’une liaison articulée 210 de type rotule qui est solidaire du support 200. Ainsi, l’utilisateur 5 (non représenté) peut diriger le manche de préhension 10 à distance (inclinaison, rotation à l’aide de la rotule 210) et donc le projecteur 24 pour allumer des zones éloignées et difficiles d’accès. Ce type de système trouve son application sur des tournages de films mais également dans des événements festifs (mariage, festival), pour la protection civile, pour les pompiers/ambulances en cas d’accident, etc. Furthermore, once the motors 35a and 35b are started and the assembly 1 is well stabilized with an angle of inclination with the determined ground (70 ° in this case), the user 5 can place the proximal end 11 of the grip handle 10 in a robust and sufficiently heavy support 200 which is placed on the ground at a chosen location. Advantageously, the proximal end 1 1 is introduced into an orifice of an articulated connection 210 of the ball type which is integral with the support 200. Thus, the user 5 (not shown) can direct the grip handle 10 at a distance (inclination , rotation using the ball 210) and therefore the projector 24 to switch on remote areas which are difficult to access. This type of system finds its application on film shoots but also in festive events (wedding, festival), for civil protection, for firefighters / ambulances in the event of an accident, etc.
Il doit être bien entendu que la description détaillée de l’objet de l'Invention, donnée uniquement à titre d'illustration, ne constitue en aucune manière une limitation, les équivalents techniques étant également compris dans le champ de la présente invention It should be understood that the detailed description of the object of the invention, given only by way of illustration, does not in any way constitute a limitation, the technical equivalents also being included in the field of the present invention
Ainsi, le nombre d’hélices 31 peut varier et être supérieur à 1 ou 2, de même que les bras d’éloignement latéral. Thus, the number of propellers 31 can vary and be greater than 1 or 2, as can the lateral distance arms.
L’outil de taille/débroussaillage 20 peut être alimenté par une source thermique. Dans ce cas un réservoir de carburant amovible sera prévu et porté par l’utilisateur pour alléger le dispositif d’élagage 1 et le carburant sera
apporté à l’outil de taille/débroussaillage 20 par l’intermédiaire d’une durite guidée par le manche de préhension 10. The pruning / clearing tool 20 can be powered by a thermal source. In this case a removable fuel tank will be provided and carried by the user to lighten the pruning device 1 and the fuel will be brought to the pruning / clearing tool 20 via a hose guided by the gripping handle 10.
Le second carénage 34a peut prendre d’autres formes que celle illustré, il peut par exemple être simplement droit ou formés de plusieurs pans inclinés (un pan droit face à l’outil et deux pans latéraux inclinés). The second fairing 34a can take other forms than that illustrated, it can for example be simply straight or formed from several inclined faces (a straight face facing the tool and two inclined side faces).
Le manche de préhension peut également être accroché, au niveau de son extrémité proximale 1 1 , à un harnais (non représenté) porté par l’utilisateur 5. The gripping handle can also be hooked, at its proximal end 11, to a harness (not shown) worn by the user 5.
Le support 200 peut être très simple et n’être constitué que d’un creux sur lequel on vient poser le manche de préhension 10 équipé d’une rotule au niveau de son extrémité proximale 1 1. The support 200 can be very simple and consist only of a recess on which the gripping handle 10 is fitted, fitted with a ball joint at its proximal end 11.
L’ensemble ainsi décrit trouve également son application dans la peinture, notamment de façades, dans le lavage de véhicules automobiles (camions), nautiques (paquebots, cargos, bateaux de plaisance à voile et/ou à moteur) ou aéronautiques (carlingue d’avions, cabine d’hélicoptères), dans le support de caméras/appareils photo et/ou de microphones pour le cinéma ou les concerts, dans le support d’appareils tel qu’une antenne ou un haut-parleur, ou encore pour permettre à une lance d’incendie d’accéder en toute sécurité à des zones dangereuses. The assembly thus described also finds its application in painting, in particular of facades, in the washing of motor vehicles (trucks), nautical (ocean liners, cargo ships, sailing and / or motorized pleasure boats) or aeronautical (cabin of planes, helicopter cabin), in the support of cameras / cameras and / or microphones for cinema or concerts, in the support of devices such as an antenna or a speaker, or even to allow a fire hose safely entering dangerous areas.
Enfin, les hélices pourront fonctionner à l’aide d’une turbine électrique ou d’un petit moteur à réaction (type modélisme).
Finally, the propellers can operate using an electric turbine or a small jet engine (model making type).
