Abstract

The invention relates to appliances for maintaining gardens. It relates in particular to an undergrowth clearing device of the type comprising a tubular handle 1 bearing at its upper end a drive motor 2 and at its lower end a bevel-gear connection 4 bearing a rotating cutting disc 5 driven rotationally by a control shaft passing through the handle 1, the handle also comprising gripping means 6, 7 making it possible for the user to hold and to guide the undergrowth clearing device.

Description

La présente invention concerne une débroussailleuse du type comportant un manche tubulaire portant à son extrémité supérieure un moteur d'entraine- ment et à son extrémité inférieure un raccord de renvoi d'angle portant un disque tournant tranchant entrainé en rotation par un arbre de commande traversant le manche, le manche comportant de plus des moyens de prise permettant à l'utilisateur de maintenir et de guider la débroussailleuse. The present invention relates to a brushcutter of the type comprising a tubular handle carrying at its upper end a drive motor and at its lower end a bevel gear connection carrying a sharp rotating disc driven in rotation by a through drive shaft the handle, the handle further comprising gripping means allowing the user to maintain and guide the brushcutter.

De tels engins présentent l'inconvénient que leur manipulation est malaisée et fatiguante pour l'utilisateur. En effet celui-ci supporte la totalité du poids de l'engin et doit maintenir le disque tranchant à une distance regulière au-dessus du sol, tout en compensant les efforts engendrés par le travail à grande vitesse de rotation de ce disque. Such devices have the disadvantage that their handling is difficult and tiring for the user. Indeed it supports the entire weight of the machine and must maintain the cutting disc at a regular distance above the ground, while compensating for the forces generated by the work at high speed of rotation of this disc.

Pour remedier à cet inconvénient, on utilise des organes de prise constitués par des véritables guidons et des sangles permettant de maintenir l'engin. Mais aucun des moyens proposés ne permet efficacement de soulager l'utilisateur. To remedy this drawback, grips are used which consist of real handlebars and straps used to hold the machine. However, none of the means proposed effectively relieves the user.

La présente invention a pour objet de concevoir une débroussailleuse du type décrit ci-dessus qui peut facilement être maintenue au-dessus du sol et être guidée sur le sol sans effort particulier. The object of the present invention is to design a brush cutter of the type described above which can easily be held above the ground and be guided over the ground without any particular effort.

Selon l'invention, ledit manche comporte dans sa partie inférieure une traverse supportant au moins deux galets montés tournant- autour d'un axe vertical et rotatif sur un axe horizontal. According to the invention, said handle comprises in its lower part a crosspiece supporting at least two rollers mounted to rotate- about a vertical axis and rotatable on a horizontal axis.

Grâce aux galets, le disque tranchant est toujours maintenu à une distance régulière au-dessus du sol et l'engin peut être orienté sans effort grâce au montage tournant des galets autour d'un axe vertical. Thanks to the rollers, the cutting disc is always kept at a regular distance above the ground and the machine can be oriented without effort thanks to the rotating mounting of the rollers around a vertical axis.

Suivant un mode de réalisation préféré de l'invention, ladite traverse est reliée au manche par un arceau fixé sur le manche par l'intermédiaire d'un collier de serrage amovible. According to a preferred embodiment of the invention, said crosspiece is connected to the handle by a hoop fixed on the handle by means of a removable clamp.

On peut ainsi ajuster sans difficultés la hauteur au-dessus du sol du disque tranchant. The height above the ground of the cutting disc can thus be adjusted without difficulty.

D'autres réalisations et avantages de l'invention ressortiront de la description qui va suivre et en se référant à la figure unique annexée montrant une vue en perspective de la débroussailleuse selon l'invention. Other embodiments and advantages of the invention will emerge from the description which follows and with reference to the single appended figure showing a perspective view of the brush cutter according to the invention.

La débroussailleuse représentée ici comporte d'une manière connue un manche tubulaire (1) portant à son extrémité supérieure un moteur d'entrainement (2) qui peut être un moteur électrique ou un moteur à combustion interne muni d'un réservoir d'essence (3). A l'extrémité inférieure du manche (1) est prévu un raccord portant le disque tranchant tournant (5) constituant l'outil de coupe de la débroussailleuse. L'inclinaison du raccord (4) par rapport au manche (l)-est telle que le disque (5) s'étend dans la position de service de la débroussailleuse dans un plan sensiblement parallèle au sol. Le disque (5) est entrainé par le moteur (2) par l'intermédiaire d'un arbre de commande (non représenté) traversant le manche (1). Sur la partie intermédiaire du manche (1) est fixé par un collier (7) un guidon (6) servant à maintenir et à guider la débroussailleuse.Le manche (1) comporte de plus un collier (9) pour la fixation d'une sangle (8) servant à soutenir l'engin et qui est engagée sur le col ou l'épaule de l'utilisateur (14) comme représenté ici. The brushcutter shown here comprises in a known manner a tubular handle (1) carrying at its upper end a drive motor (2) which can be an electric motor or an internal combustion engine provided with a fuel tank ( 3). At the lower end of the handle (1) is provided a fitting carrying the rotating cutting disc (5) constituting the cutting tool of the brush cutter. The inclination of the connector (4) relative to the handle (l) -is such that the disc (5) extends in the operating position of the brushcutter in a plane substantially parallel to the ground. The disc (5) is driven by the motor (2) via a control shaft (not shown) passing through the handle (1). On the intermediate part of the handle (1) is fixed by a collar (7) a handlebar (6) used to hold and guide the brushcutter.The handle (1) further comprises a collar (9) for fixing a strap (8) used to support the machine and which is engaged on the neck or shoulder of the user (14) as shown here.

Selon la présente invention, le manche (1) porte dans sa partie inférieure deux galets (11) montés tournant autour d'axes verticaux sur une traverse (10). Cette dernière est supportée par un arceau (12) fixé par un collier (13) sur le manche (1). L'emplacement de l'ensemble (10 à 13) sur le manche (1) est réglable et choisi d'une manière telle que le disque (5) s'étend à une distance prédéterminée au-dessus du sol. Grâce à cette disposition, l'effort fourni par l'utilisateur (14) pour soutenir et guider l'en- gin est considérablement réduit. Ce guidage peut être effectué librement et sans effort grâce au montage tournant des galets (11). According to the present invention, the handle (1) carries in its lower part two rollers (11) mounted rotating around vertical axes on a crosspiece (10). The latter is supported by a hoop (12) fixed by a collar (13) on the handle (1). The location of the assembly (10 to 13) on the handle (1) is adjustable and chosen in such a way that the disc (5) extends at a predetermined distance above the ground. Thanks to this arrangement, the effort provided by the user (14) to support and guide the machine is considerably reduced. This guidance can be carried out freely and effortlessly thanks to the rotating mounting of the rollers (11).

Bien entendu, l'invention n'est pas limité au mode de réalisation décrit et représenté ici, mais on peut y apporter de nombreuses modifications sans pour cela sortir du cadre de l'invention.  Of course, the invention is not limited to the embodiment described and shown here, but many modifications can be made without departing from the scope of the invention.
