Description

Dispositif de support, de positionnement et de guidage d'un outil. Device for supporting, positioning and guiding a tool.
La présente invention se rapporte au domaine des dispositifs de support et de guidage d'outils montés sur un axe et plus particulièrement au domaine des dispositifs de support et de guidage d'outils de débroussaillage 5et d'élagage.The present invention relates to the field of devices for supporting and guiding tools mounted on an axis and more particularly to the field of devices for supporting and guiding brushing and pruning tools.
Lors d'une opération de débroussaillage, l'outil utilisé généralement est une débroussailleuse formée par un disque comportant une ou plusieurs lames montées en rotation, ce disque se trouvant positionné à l'extrémité d'un élément axial de support porté à bras, de sorte que l'utilisateur puisse lOpositionner correctement l'outil de coupe au niveau des surfaces à débroussailler. Cependant, lorsque le débroussaillage vient s'opérer sur des surfaces de taille importante, le poids de l'outil de débroussaillage, c'est-à- dire des moyens de coupe, de l'élément de support, mais également du moteur d'entraînement des moyens de coupe, fatigue rapidement l'utilisateurIn a brushcutting operation, the tool generally used is a brushcutter formed by a disc having one or more rotatably mounted blades, this disc being positioned at the end of an axial support element carried by arm, from so that the user can correctly position the cutting tool at the level of the brushcutter surfaces. However, when the brushing is performed on large surfaces, the weight of the brushcutter tool, that is to say, cutting means, the support member, but also the engine of drive cutting means, quickly fatigue the user
15de l'appareil.15of the device.
Pour réduire la fatigue tout en conservant une autonomie de mouvement optimale dans le guidage de l'outil de coupe, il est courant d'utiliser un harnais porté par l'utilisateur entre sa taille et ses épaules auquel vient s'accrocher l'appareil de débroussaillage par son élément axial de 20support. Le poids de l'outil se trouve alors supporté par l'ensemble du corps de l'utilisateur et non plus uniquement par ses bras. Toutefois, si le transport de l'appareil de coupe grâce à un harnais permet de réduire l'effet du poids de l'appareil sur les membres de l'utilisateur, une utilisation prolongée de l'outil de débroussaillage fatigue rapidement l'utilisateur.To reduce fatigue while maintaining optimal movement autonomy in the guidance of the cutting tool, it is common to use a harness worn by the user between his waist and his shoulders to which hangs the device of brushing by its axial element of 20support. The weight of the tool is then supported by the entire body of the user and not only by his arms. However, if the transport of the cutting apparatus with a harness makes it possible to reduce the effect of the weight of the apparatus on the members of the user, prolonged use of the brushcutter tool quickly fatigues the user.
25 La présente invention a pour objet de palier un ou plusieurs inconvénients de l'art antérieur et notamment de proposer un dispositif de support, de positionnement et de guidage d'appareil de débroussaillage permettant de limiter voire de supprimer la fatigue généré par le port et le transport de l'appareil de débroussaillage lors de son utilisation au cours de périodes prolongées, tout en permettant une adaptation du dispositif à d'autres appareils.The object of the present invention is to overcome one or more disadvantages of the prior art and in particular to propose a device for supporting, positioning and guiding a brushcutter device making it possible to limit or even eliminate the fatigue generated by the port and the transport of the brushcutter during its use during the periods, while allowing the device to be adapted to other devices.
Cet objectif est atteint grâce à un dispositif de support, de positionnement et de guidage d'un outil monté à une extrémité d'un élémentaxial de support d'outil caractérisé en ce que le dispositif de support comprend :This object is achieved by means of a device for supporting, positioning and guiding a tool mounted at one end of an axial tool support element, characterized in that the support device comprises:

The device can then, for example and without limitation, be used
15avec des outils d'élagage ou bien encore avec des outils de détection de métaux ou de déminage.15 with pruning tools or with tools for detecting metals or demining.
L'outil (1) supporté par le dispositif de l'invention se trouve positionné à une des extrémités d'un élément axial de support (2). Cet élément de support (2) forme ainsi un axe par lequel l'utilisateur peut contrôler leThe tool (1) supported by the device of the invention is positioned at one end of an axial support member (2). This support element (2) thus forms an axis by which the user can control the
20déplacement et le positionnement de l'outil à distance. L'élément de support (2) est monté mobile sur un mât (3) du dispositif au niveau d'une première articulation (5). Oe même, l'extrémité inférieure du mât (3) du dispositif est montée pivotante sur une embase (4) au niveau d'une seconde articulation (6), l'embase assurant le contact du dispositif avec le sol et/ou la surface sur20displacement and positioning of the tool remotely. The support member (2) is movably mounted on a mast (3) of the device at a first articulation (5). Similarly, the lower end of the mast (3) of the device is pivotally mounted on a base (4) at a second articulation (6), the base ensuring the contact of the device with the ground and / or the surface sure
25laquelle l'outil (1) est destiné à venir opérer. Ainsi, l'élément de support (2) et le mât (3) du dispositif s'articulent comme les deux branches d'une paire de ciseaux au niveau de la première articulation (5), avec une première extrémité du dispositif en contact avec le sol au niveau de l'embase (4) et une seconde extrémité du dispositif fixée à l'outil (1). L'importance deWhich tool (1) is intended to operate. Thus, the support element (2) and the mast (3) of the device articulate like the two branches of a pair of scissors at the first articulation (5), with a first end of the device in contact with the the floor at the base (4) and a second end of the device attached to the tool (1). The importance of
30l'écartement entre l'élément de support (2) et le mât (3) du dispositif au niveau de la première articulation (5) permet d'éloigner ou de rapprocher l'outil (1) de l'embase (4).The distance between the support element (2) and the mast (3) of the device at level of the first articulation (5) makes it possible to move the tool (1) away from or towards the base (4).
Selon un premier mode de réalisation, l'utilisateur déplace et positionne l'outil (1) grâce à un moyen de guidage (7) positionné à hauteur 5de bras sur l'élément de support (2) de l'outil entre l'extrémité où est monté l'outil (1) et l'articulation (5) de l'élément de support (2) avec le mât (3).According to a first embodiment, the user moves and positions the tool (1) by means of a guide means (7) positioned at arm height on the support element (2) of the tool between the end wherein is mounted the tool (1) and the hinge (5) of the support member (2) with the mast (3).
Selon un second mode de réalisation, le déplacement et le positionnement de l'outil (1) par l'utilisateur sont assuré par deux moyens de guidage positionnés respectivement au niveau des extrémités de l'élément lOde support (2) et du mât (3) du dispositif positionnée à l'opposée des extrémités qui respectivement supporte l'outil (1) ou fixe l'embase (4).According to a second embodiment, the movement and positioning of the tool (1) by the user is ensured by two guiding means positioned respectively at the ends of the support member (2) and the mast (3). ) of the device positioned opposite the ends which respectively support the tool (1) or fixed the base (4).
Ces moyens de guidage peuvent, par exemple, être formés par un guidon ou une poignée de contrôle, etc. et sont adaptables en hauteur à la morphologie de l'utilisateur.These guide means may, for example, be formed by a handlebar or a control handle, etc. and are adaptable in height to the morphology of the user.
15 L'élément de support (2) de l'outil (1) et le mât (3) du dispositif forment deux éléments dont les structures sont sensiblement rectilignes et montées mobiles l'une par rapport l'autre autour d'un pivot qui forme un axe (A) perpendiculaire à chacun des axes respectifs de chacun des deux éléments (2, 3). Les sections respectives de l'élément de support (2) et duThe support member (2) of the tool (1) and the mast (3) of the device form two elements whose structures are substantially rectilinear and movably mounted relative to each other around a pivot which forms an axis (A) perpendicular to each of the respective axes of each of the two elements (2, 3). The respective sections of the support member (2) and the
20mât (3) peuvent être de toute forme : par exemple cylindrique, ovale, ovoïde, carré, rectangulaire, etc. Lors du mouvement de pivotement autour de l'axe (A), l'élément de support (2) et le mât (3) viennent réaliser des déplacements dans des plans respectifs parallèles entre eux. Ces déplacements de l'élément de support (2) et du mât (3) réalisent ainsi un cisaillement.20mast (3) can be of any shape: for example cylindrical, oval, ovoid, square, rectangular, etc. During the pivoting movement about the axis (A), the support member (2) and the mast (3) are made to move in respective planes parallel to each other. These displacements of the support element (2) and the mast (3) thus achieve a shear.
25 Selon un mode de réalisation particulier, l'articulation (5) de l'élément de support (2) de l'outil (1) avec le mât (3) du dispositif est réalisée grâce à au moins une tige (5b), par exemple filetée ou partiellement filetée, fixée par une de ses extrémités au mât (3) du dispositif perpendiculairement à l'axe du mât (3). La tige filetée (5b), qui vient former un pivot dans l'articulation (5),According to a particular embodiment, the articulation (5) of the support element (2) of the tool (1) with the mast (3) of the device is achieved by means of at least one rod (5b), for example threaded or partially threaded, fixed by one of its ends to the mast (3) of the device perpendicular to the axis of the mast (3). The threaded rod (5b), which comes to form a pivot in the articulation (5),
30traverse également un alésage de l'élément de support (2) orienté perpendiculairement à l'axe de l'élément de support (2). Entre l'élément de support (2) et le mât (3) du dispositif, une entretoise (5c) se trouve positionnée, traversée par la tige (5b) filetée, de façon à faciliter l'articulation de l'élément de support (2) par rapport à l'outil (1). L'extrémité de la tige 5fιletée (5b) qui n'est pas fixée sur le mât (3) comprend alors un moyen de serrage de l'élément (2) de support contre l'entretoise (5c) de l'articulation (5), ce moyen de serrage pouvant être par exemple un écrou de type papillon ou à oreilles.30traverse also a bore of the support member (2) oriented perpendicular to the axis of the support member (2). Between the support element (2) and the mast (3) of the device, a spacer (5c) is positioned, traversed by the threaded rod (5b), so as to facilitate the articulation of the support element ( 2) relative to the tool (1). The end of the 5fιletée rod (5b) which is not fixed on the mast (3) then comprises a means for clamping the support member (2) against the spacer (5c) of the articulation (5). ), this clamping means being for example a butterfly or wing type nut.
Selon une variante de fixation mobile de la tige (5b) à l'élément axial lOde support (2) de l'outil (1), cette fixation fait intervenir un élément d'articulation (9) monté sur l'élément (2) axial de support. Cet élément d'articulation (9) comprend alors au moins un espace orienté perpendiculairement à l'axe de l'élément (2) axial de support de l'outil (1). La tige (5b) qui joue le rôle de pivot dans l'articulation (5) vient se positionnerAccording to a variant of movable attachment of the rod (5b) to the axial element 10 of support (2) of the tool (1), this attachment involves a hinge element (9) mounted on the element (2) axial support. This hinge element (9) then comprises at least one space oriented perpendicular to the axis of the axial support element (2) of the tool (1). The rod (5b) which acts as a pivot in the articulation (5) is positioned
15dans cet espace de façon à uniquement être autorisée à réaliser une rotation axiale selon l'axe de la tige-pivot (5b) et selon l'axe de l'espace de l'élément d'articulation (9). La tige (5b) permet ainsi d'articuler l'élément axial de support (2) sans nécessiter un alésage dans cet élément (2) de support lorsque, par exemple, celui intègre un axe de transmission entre l'outil (1) et15in this space so as to only be allowed to perform axial rotation along the axis of the pivot rod (5b) and along the axis of the space of the hinge member (9). The rod (5b) thus makes it possible to articulate the axial support element (2) without requiring a bore in this support element (2) when, for example, that integrates a transmission axis between the tool (1) and
20un moteur positionné à l'autre extrémité de l'élément (2) de support.A motor positioned at the other end of the support member (2).
Selon une variante de réalisation de l'articulation (5), la tige filetée (5b) est fixé au mât (3) du dispositif par l'intermédiaire d'un élément mobile (5a) qui peut se déplacer le long d'au moins une portion continue de l'axe du mât (3) du dispositif. Cet élément mobile (5a) permet de modifier le 25positionnement de l'axe de pivotement le long du mât (3) et ainsi d'améliorer le positionnement de l'outil lorsque l'écartement entre l'élément de supportAccording to an alternative embodiment of the articulation (5), the threaded rod (5b) is fixed to the mast (3) of the device via a movable element (5a) which can move along at least a continuous portion of the axis of the mast (3) of the device. This movable element (5a) makes it possible to modify the positioning of the pivot axis along the mast (3) and thus to improve the positioning of the tool when the distance between the support element
(2) et le mât (3) au niveau de l'articulation (5) est maximal.(2) and the mast (3) at the joint (5) is maximum.
Selon un mode de réalisation particulier du dispositif de l'invention, l'élément mobile (5a) est formé par un manchon. Ce manchon (5a) est montéAccording to a particular embodiment of the device of the invention, the movable element (5a) is formed by a sleeve. This sleeve (5a) is mounted
30coulissant sur au moins une portion continue de la longueur de l'axe du mât30coulding on at least one continuous portion of the length of the axis of the mast
(3) du dispositif. Le manchon (5) forme un tube de section similaire à celle de l'axe du mât (3) mais dont les dimensions intérieures de la section sont sensiblement supérieures et/ou égales aux dimensions extérieures de la section du mât (3) au niveau de la portion destinée au coulissage. Cette portion, où le coulissage est autorisé, est définie par au moins deux butées 5qui se trouvent positionnées à chaque extrémité de la portion de l'axe du mât (3). Le mât (3) présentant une extrémité basse qui s'articule avec l'embase (4), il permet alors de définir sur son axe une butée haute (5a 1) et une butée basse (5a2) de part et d'autre de la portion de coulissage du mât (3). Dans une variante de réalisation, pour s'assurer que le manchon (5a) ne coulisse lOque le long de la longueur de l'axe du mât (3) et ne réalise pas une rotation sur son axe, une solution consiste à faire en sorte que les sections de l'axe du mât (3) et du manchon (5a) ne soient pas circulaires.(3) of the device. The sleeve (5) forms a tube of section similar to that of the axis of the mast (3) but whose internal dimensions of the section are substantially greater and / or equal to the outer dimensions of the mast section (3) at the portion intended for sliding. This portion, where the sliding is allowed, is defined by at least two stops 5 which are positioned at each end of the portion of the axis of the mast (3). The mast (3) having a low end which articulates with the base (4), it then allows to define on its axis an upper stop (5a 1) and a lower stop (5a2) on either side of the sliding portion of the mast (3). In an alternative embodiment, to ensure that the sleeve (5a) slides along the length of the axis of the mast (3) and does not rotate on its axis, one solution is to make sure that the sections of the axis of the mast (3) and the sleeve (5a) are not circular.
Selon un autre mode de réalisation du dispositif de l'invention, l'élément mobile (5a) est formé par un prolongement du pivot de l'articulationAccording to another embodiment of the device of the invention, the movable element (5a) is formed by an extension of the pivot of the articulation
15(5). Ce prolongement vient se positionner dans l'épaisseur de l'axe du mât (3) du dispositif au niveau d'une fente (11) qui est disposée dans la longueur du mât (3) est traverse le mât dans sa largeur, la longueur de cette fente (11 ) venant définir la portion de l'axe du mât (3) sur laquelle l'articulation (5) est mobile. De part et d'autre du mât (3), cette fente (11) présente un orifice15 (5). This extension is positioned in the thickness of the axis of the mast (3) of the device at a slot (11) which is arranged in the length of the mast (3) is traversed by the mast in its width, the length this slot (11) defining the portion of the axis of the mast (3) on which the hinge (5) is movable. On both sides of the mast (3), this slot (11) has an orifice
20sensiblement allongé voire oblong. Dans cette fente (11), le prolongement du pivot est maintenu en position par un moyen de serrage monté à son extrémité située du coté opposé à l'articulation (5) de l'élément de support (2) avec le mât (3). Ce moyen de serrage empêche tout déplacement selon l'axe (B) du pivot et du prolongement. Dans la fente (11), le prolongement et20sensibly elongated or oblong. In this slot (11), the extension of the pivot is held in position by a clamping means mounted at its end located on the opposite side to the articulation (5) of the support member (2) with the mast (3). . This clamping means prevents any displacement along the axis (B) of the pivot and the extension. In the slot (11), the extension and
25l'articulation (5) ne sont autorisés qu'à réaliser des mouvements de translations selon une direction perpendiculaire à l'axe du prolongement et confondue avec l'axe du mât (3).The articulation (5) is only allowed to perform translation movements in a direction perpendicular to the axis of the extension and coincident with the axis of the mast (3).
Selon une particularité de réalisation, le dispositif comprend au moins un ressort de rappel (10) dont une première extrémité est fixée surAccording to a particular embodiment, the device comprises at least one return spring (10) whose first end is fixed on
