Abstract

It comprises two approximately semi-cylindrical spades (21, 22) located facing one another and secured by their upper ends to a flat iron (23) bent into a U to which the spade (21) is welded while the spade (22) is mounted so that it can pivot about a horizontal pin (24) secured to the flat iron (23); a vertical tube (25) secured to the flat iron (23) approximately at its middle, to which a flyweight (27) is slidingly mounted; an elbowed tube (29) secured to the upper edge of the spade (22) and the upper end of which is connected to that of the tube (25) through the use of two coaxial horizontal cylinders (31, 32) forming a hand grip (3) and one of which, the cylinder (32), is closed and can be entirely housed in the cylinder (31) which encloses a coil spring (33) positioned between its closed end and the end of the cylinder (32) which it pushes back, which has the effect of moving the tube (29) away from the tube (25), thus exerting a lateral pressure on the spade (22) which keeps it pressed against the spade (21) during the entire duration of their penetration into the ground.

Description

La présente invention a pour objet un outil à main utile dans le domaine de la culture, notamment des légumes, cet outil permettant de creuser des trous dans la terre afin d'y planter des plants ou des bulbes. The present invention relates to a hand tool useful in the field of cultivation, in particular vegetables, this tool making it possible to dig holes in the ground in order to plant plants or bulbs therein.

On utilise habituellement à cet effet des petites pelles au bout effilé, dont la mise en oeuvre nécessite plusieurs opérations pour creuser et évacuer la terre, le trou devant avoir un certain diamètre et une certaine profondeur. Small shovels with a tapered end are usually used for this purpose, the implementation of which requires several operations to dig and remove the earth, the hole having to have a certain diameter and a certain depth.

La présente invention a pour but de remédier à cet inconvénient en proposant un outil qui permet de faire un trou de la dimension voulue et d'évacuer la terre en une seule opération. The object of the present invention is to remedy this drawback by proposing a tool which makes it possible to make a hole of the desired size and to remove the earth in a single operation.

L'outil selon l'invention est constitué de deux pelles semi-cylindriques disposées en regard et solidarisées à leur extrémité supérieure, formant ensemble un emporte-pièce au-dessus duquel est soudé un tube, muni à son autre extrémité d'une poignée, autour duquel peut coulisser une masselotte. The tool according to the invention consists of two semi-cylindrical shovels arranged opposite and secured at their upper end, together forming a cookie cutter above which a tube is welded, provided at its other end with a handle, around which a flyweight can slide.

Pour creuser un trou, on applique les deux pelles à l'endroit choisi, puis on fait faire manuellement des aller et retour à la masselotte le long du tube, de manière à ce qu'elle vienne frapper le fer plat qui solidarise les deux pelles, lesquelles s'enfoncent dans le sol. Lorsqu'on retire l'outil on évacue la terre restée entre les deux pelles en faisant pivoter l'une d'elles qui est mobile autour d'un axe horizontal, et qu'un système de ressort et de levier maintient appliquée contre l'autre pendant toute la durée de la pénétration dans le sol. To dig a hole, we apply the two shovels at the chosen location, then we go back and forth manually with the flyweight along the tube, so that it comes to strike the flat iron which secures the two shovels , which sink into the ground. When the tool is removed, the earth remaining between the two shovels is removed by rotating one of them which is movable about a horizontal axis, and which a system of spring and lever keeps applied against the other throughout the duration of penetration into the ground.

Les caractéristiques et avantages de la présente invention ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif. The characteristics and advantages of the present invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents a non-limiting embodiment thereof.

Dans le dessin annexé
- la figure 1 représente une vue en perspective avec arraché partiel d'un outil selon l'invention en position fermée.
In the attached drawing
- Figure 1 shows a perspective view with partial cutaway of a tool according to the invention in the closed position.

- la figure 2 représente une vue en perspective du même outil en position ouverte. - Figure 2 shows a perspective view of the same tool in the open position.

Si on se réfère à la figure 1, on voit que le plantoir selon l'invention est constitué d'une pelle 21 et d'une pelle 22 de forme approximativement semi-cylindrique, dont le diamètre augmente légèrement de la partie inférieure à la partie supérieure. Les parties concaves des deux pelles se font face, formant un emporte-pièce.  If we refer to Figure 1, we see that the dibber according to the invention consists of a shovel 21 and a shovel 22 of approximately semi-cylindrical shape, the diameter of which increases slightly from the lower part to the part superior. The concave parts of the two shovels face each other, forming a cookie cutter.

Au-dessus des deux pelles est fixé un fer plat 23 plié en U, soudé à la pelle 21 et solidarisé à la pelle 22 par l'intermédiaire d'un axe transversal horizontal 24, permettant à la pelle 22 de pivoter par rapport à la pelle 21. Above the two shovels is fixed a flat iron 23 folded in a U, welded to the shovel 21 and secured to the shovel 22 by means of a horizontal transverse axis 24, allowing the shovel 22 to pivot relative to the shovel 21.

Sur le fer plat 23, approximativement en son milieu, se trouve fixé un tube vertical 25 dont la base est entourée d'un anneau métallique 26 servant de butoir à une masselotte 27, constituée d'un cylindre métallique muni de deux perçages axiaux monté coulissant sur le tube 25, entre le butoir 26 et un butoir 28 constitué d'un anneau métallique soudé à l'autre extrémité dudit tube 25. On the flat iron 23, approximately in the middle, there is fixed a vertical tube 25, the base of which is surrounded by a metal ring 26 serving as a stopper for a counterweight 27, consisting of a metal cylinder provided with two axial holes mounted to slide. on the tube 25, between the stopper 26 and a stopper 28 consisting of a metal ring welded to the other end of said tube 25.

Un tube coudé 29 est par ailleurs soudé obliquement au bord supérieur de la pelle 22, approximativement en son milieu. Ce tube 29 est coudé non loin de son extrémité inférieure et s'écarte sur toute sa longueur du tube 25. A bent tube 29 is also welded obliquely to the upper edge of the shovel 22, approximately in the middle. This tube 29 is bent not far from its lower end and deviates over its entire length from the tube 25.

Une poignée cylindrique horizontale 3 est fixée entre les deux extrémités supérieures des tubes 25 et 29, permettant de tenir le plantoir d'une main pendant que l'autre main déplace la masselotte 27. La poignée 3 est constituée de deux cylindres 31 et 32 coaxiaux, le cylindre 32, fermé, pouvant se loger entièrement dans le cylindre 31, qui est fermé à son extrémité voisine du tube 25. Un ressort à boudin 33 est placé à l'intérieur du cylindre 31, entre son extrémité fermée et l'extrémité du cylindre 32, repoussant le cylindre 32, ce qui a pour effet d'écarter le tube 29 du tube 25, et par voie de conséquence d'exercer sur la pelle 22 une pression latérale qui la maintient appliquée contre la pelle 21. A horizontal cylindrical handle 3 is fixed between the two upper ends of the tubes 25 and 29, making it possible to hold the dibber with one hand while the other hand moves the counterweight 27. The handle 3 consists of two coaxial cylinders 31 and 32 , the cylinder 32, closed, which can be entirely housed in the cylinder 31, which is closed at its end close to the tube 25. A coil spring 33 is placed inside the cylinder 31, between its closed end and the end of the cylinder 32, pushing the cylinder 32, which has the effect of moving the tube 29 from the tube 25, and consequently exerting on the shovel 22 a lateral pressure which keeps it applied against the shovel 21.

La figure 2 permet de voir que si l'on comprime le ressort 33 en rapprochant les tubes 25 et 29, on fait pivoter la pelle 22 autour de l'axe 24, l'écartant de la pelle 21 suffisamment pour que la terre puisse s'évacuer. Figure 2 shows that if the spring 33 is compressed by bringing the tubes 25 and 29 together, the shovel 22 is pivoted about the axis 24, moving it away from the shovel 21 enough so that the earth can s 'clear out.

Deux petites saillies 3 ménagées bilatéralement sur la pelle 21, approximativement à mi-hauteur, servent de guides à la pelle 22, pour qu'elle se positionne correctement en face de la pelle 21 lorsqu'on relâche la pression sur le ressort 33.  Two small projections 3 arranged bilaterally on the shovel 21, approximately halfway up, serve as guides for the shovel 22, so that it is positioned correctly in front of the shovel 21 when the pressure on the spring 33 is released.
