A tubular frame with handles and adjustable support rod carries the drill, the drive shaft and protective guards over the tools. A drive shaft runs the length of the tool and is carried in a tube which acts both as protective housing and central spine of the tool. The top of the shaft projects beyond the tube and can be fitted to the chuck of an electric hand drill. A protective cover fitted over the upper end of the tube covers the drill chuck. The lower end of the drive shaft carries a wormgear and a bevel gear, the worm gear driving the horizontal output shaft, and the bevel gear the vertical. The gears are enclosed in a casing, and a guard is fitted to the spine tube to protect the user.

Description

La présente invention a pour objet un dispositif perfectionné pour le jardinage permettant d'effectuer différents travaux, notamment le binage, le débroussaillage, sans nécessiter l'achat d'un matériel onéreux. The subject of the present invention is an improved device for gardening making it possible to carry out various works, in particular hoeing, brush cutting, without requiring the purchase of expensive equipment.

Actuellement, il existe sur le marché des engins motorisés autonomes permettant d'effectuer ces travaux tels que des motobineuses, mais ils sont lourds et demandent un investissement important. Currently, there are autonomous motorized devices on the market allowing this work to be carried out, such as power hoes, but they are heavy and require significant investment.

La présente invention a pour objet un dispositif simple, léger, robusté, permettant d'effectuer différents travaux de jardinage d'un prix de revient très bas. Ce dispositif ne comporte pas de moteur. Pour son entraînement, on l'adapte simplement sur un bloc-moteur du commerce, par exemple une perceuse. The present invention relates to a simple, light, robust device for performing various gardening works at a very low cost price. This device does not include a motor. For its training, it is simply adapted on a commercial engine block, for example a drill.

Le dispositif sélon l'invention est constitué d'un axe d'entraînement disposé à l'intérieur d'un tube-guide dont une extrémité peut etre rendue solidaire du mandrin d'une perceuse et dont l'autre extrémité entraîne une vis sans fin engrenant une roue dentée tangente portant un axe sur lequel seront adaptés différents outils. L'extrémité de l'axe d'entranement est pourvu également d'un engrenage de renvoi d'angle permettant de disposer d'outils travaillant dans un autre plan. The device according to the invention consists of a drive pin arranged inside a guide tube, one end of which can be made integral with the mandrel of a drill and the other end of which drives an endless screw. meshing a tangent gear carrying an axis on which different tools will be adapted. The end of the drive shaft is also provided with a bevel gear making it possible to have tools working in another plane.

Le dispositif selon l'invention comporte > en outre, deux mancherons réglables, une béquille permettant de prendre appui sur le sol et un harnais pour le porter. The device according to the invention comprises> in addition, two adjustable handlebars, a stand making it possible to rest on the ground and a harness for carrying it.

Le dispositif selon l'invention sera mieux compris à la lecture de la description qui suit d'une de ses réalisations préférées et à l'examen des dessins annexés sur lesquels
- la figure 1 est une vue en perspective du dispositif selon l'invention, monté sur une perceuse;
- la figure 2 est une vue en coupe du dispositif de la figure 1;
- la figure 3 est une vue partielle de face montrant le montage des outils de travail;
- la figure 4 est une vue en perspective d'une variante de l'invention. The device according to the invention will be better understood on reading the following description of one of its preferred embodiments and on examining the appended drawings in which
- Figure 1 is a perspective view of the device according to the invention, mounted on a drill;
- Figure 2 is a sectional view of the device of Figure 1;
- Figure 3 is a partial front view showing the assembly of the working tools;
- Figure 4 is a perspective view of a variant of the invention.

En se reportant aux figures 1 et 2, on voit que le dispositif selon l'invention comporte un tube-guide 1 à l'intérieur duquel est disposé un axe d'entraînement 2, maintenu par deux paliers 3 et 4. L'une des extrémités 5 de l'axe d'entraînement est rendue solidaire du mandr-in d'une perceuse 6. Afin d'éviter tout accident, le mandrin de la perceuse 6 vient se loger à l'intérieur d'un cône de protection 7 soudé sur le tube-guide 1. L'autre extrémité de l'axe d'entraînement 2 entraîne une vis sans fin 8 engrenant une roue dentée 9 disposée tangentiellement et dont l'axe 10, perpendiculaire à l'axe d'entraînement 2, recevra de chaque côté les outils de travail. Le rapport entre la vis sans fin 8 et la roue dentée 9 est calculé de façon telle que l'axe 10 constitue une sortie lente, c'est-à-dire tourne à environ 150 tours/ minute.Sur l'axe-d'entratnement 2 est calé également un engrenage de renvoi d'angle 11 coopérant avec un second engrenage identique 12 dont l'axe 13 sort à 450 dans le plan vertical par rapport à l'axe d'entraînement 2. Cet axe 13 constitue une sortie rapide, le rapport des engrenages de renvoi d'angle 11 et 12 étant tel qu'il tourne à plus de 4500 tours/minute environ. L'ensemble de ces éléments est enfermé dans un carter de protection 14, qui peut éventuell-e- ment contenir un bain d'huile. Sur le tube 1 sont montés deux mancherons 15 réglables en hauteur au moyen d'une fixation en matière plastique 16, et une béquille repliable 17 articulée sur la fixation 16. Par ailleurs, une tôle de protection 18 est disposée à l'extrémité inférieure du tube, au-dessus du carter 14.Un harnais 19 peut avantageusement être adapté à-ltensemble.  Referring to Figures 1 and 2, we see that the device according to the invention comprises a guide tube 1 inside which is disposed a drive shaft 2, held by two bearings 3 and 4. One of the ends 5 of the drive shaft is made integral with the mandr-in of a drill 6. In order to avoid any accident, the mandrel of the drill 6 is housed inside a protective cone 7 welded on the guide tube 1. The other end of the drive shaft 2 drives an endless screw 8 meshing with a toothed wheel 9 disposed tangentially and whose axis 10, perpendicular to the drive axis 2, will receive the work tools on each side. The ratio between the worm screw 8 and the toothed wheel 9 is calculated in such a way that the axis 10 constitutes a slow output, that is to say rotates at approximately 150 revolutions / minute. drive 2 is also wedged a bevel gear 11 cooperating with a second identical gear 12 whose axis 13 exits at 450 in the vertical plane relative to the drive axis 2. This axis 13 constitutes a rapid output , the ratio of the bevel gear 11 and 12 being such that it rotates at more than around 4500 rpm. All of these elements are enclosed in a protective casing 14, which may optionally contain an oil bath. On the tube 1 are mounted two handlebars 15 adjustable in height by means of a plastic attachment 16, and a folding stand 17 articulated on the attachment 16. Furthermore, a protective plate 18 is arranged at the lower end of the tube, above the casing 14. A harness 19 can advantageously be adapted to the assembly.

Le dispositif peut être utilisé avec la sortie lente 10 comme tondeuse hélicoîdale, scarificateur, aérateur, bineuse, balayeuse. Avec la sortie rapide 13, il peut être utilisé comme débroussailleuse, ou ponceuse par exemple. The device can be used with the slow output 10 as a helical mower, scarifier, aerator, cultivator, sweeper. With the quick outlet 13, it can be used as a brushcutter, or sander for example.

L'axe de sortie 13 a la particularité d'être amovible.The output axis 13 has the distinction of being removable.

Sur la figure 3, on voit de face l'extrémité du tube 1 avec la tôle de protection 18 et le carter 14. Sur l'axe de sortie 10 sont montées des fraises 20 pour le binage, aucun outil n'étant monté sur l'axe 13.  In Figure 3, we see from the front the end of the tube 1 with the protective plate 18 and the casing 14. On the output axis 10 are mounted cutters 20 for hoeing, no tool being mounted on the axis 13.

Sur la figure 4, on a représenté une variante du dispositif selon l'invention. Dans cette réalisation, la perceuse 6 est adaptée comme dans l'exemple précédemment décrit sur un tube 1, de longueur plus courte. L'ensemble ainsi formé est fixé sur un second tube-support 21 au moyen d'une fixation 22. Ce tube porte deux mancherons 15 et la béquille repliable 17. Cette variante a pour objet de faire descendre le centre de gravité de ensemble plus près du sol, afin d'en assurer une plus grande maniabilité. In Figure 4, there is shown a variant of the device according to the invention. In this embodiment, the drill 6 is adapted as in the example previously described on a tube 1, of shorter length. The assembly thus formed is fixed on a second support tube 21 by means of a fixing 22. This tube carries two handlebars 15 and the folding stand 17. The purpose of this variant is to bring the center of gravity of the assembly closer together. of the ground, in order to ensure greater maneuverability.

Le dispositif selon l'invention permet d'utiliser le moyen le plus simple, une perceuse portative, pour entraîner des outils de jardinage les plus divers, afin de réaliser un ensemble polyvalent bon marché, de faible poids, donc très maniable. Dans le cas d'un dispositif de binage, la béquille d'enterrage (non représentée) est solidaire du capot 18.  The device according to the invention makes it possible to use the simplest means, a portable drill, to drive the most diverse gardening tools, in order to produce an inexpensive versatile assembly, of low weight, therefore very handy. In the case of a hoeing device, the burial stand (not shown) is integral with the cover 18.
