Abstract
Description
[: La présente invention concerne un dispositif articulé qui, adapté à une fourche- bêche outil de jardinage connu, permet de retourner la terre ou le sable au bord de mer avec facilité et un effort moindre. [: The present invention relates to an articulated device which, adapted to a pitchfork known gardening tool, allows to return the earth or sand to the seaside with ease and less effort.
Traditionnellement l'utilisation d'une fourche- bêche comporte deux opérations essentielles
Tout d'abord il faut planter les fourches de l'outil dans le sol après positionnement préalable en s'aidant de la force musculaire des jambes
Ensuite on exerce un effort vers le bas sur le manche de l'outil afin de retourner le chargement. Ici le résultat escompté n'est pas à la mesure des efforts dépensés . En effet le point d'appui du levier en contact avec le sol sous l'effet de la rotation de l'outil et sa faible surface de contact a tendance à s'enfoncer dans le sol sous l'effet de l'effort appliqué Le manche de l'outil étant en position basse et le chargement encore enterré dans le sol, il faut procéder à une opération supplémentaire et pénible qui consiste à soulever en force le contenu de la fourche- bêche qui n'a pas encore décollé du sol et ceci dans de mauvaises conditions
Le dispositif selon l'invention permet de remédier à cet inconvénient
Adapté à la fourche- bêche, il permet d'améliorer son fonctionnement et son rendement en modifiant la position et la surface du point d'appui du chargement tout en l'articulant autour d'un l'axe.Traditionally the use of a spade fork involves two essential operations
First of all, the forks of the tool must be planted in the ground after prior positioning, using the muscular strength of the legs.
Then we exert a downward force on the handle of the tool in order to return the load. Here the expected result is not commensurate with the efforts expended. Indeed, the fulcrum of the lever in contact with the ground under the effect of the rotation of the tool and its small contact surface tends to sink into the ground under the effect of the force applied. the handle of the tool being in the low position and the load still buried in the ground, it is necessary to carry out an additional and painful operation which consists in forcibly lifting the contents of the spade fork which has not yet taken off from the ground and this in bad conditions
The device according to the invention overcomes this drawback
Adapted to the fork-spade, it improves its operation and its output by modifying the position and the surface of the load support point while articulating it around an axis.
I1 comporte selon une première caractéristique une pièce réglable en hauteur en forme de U. La partie horizontale de ce profilé importante en surface est prévue pour être en contact avec le sol Fixé sur la partie supérieure externe de l'outil sur lequel on aura prévu des bossages percés de trous, il est solidaire de la fourche- bêche et articulé par l'intermédiaire d'un axe. Les parties verticales du dispositif comportent des trous situés à différentes altitudes et placés au dessus de son centre de gravité .permettant ainsi et suivant la position choisie d'adapter la hauteur idéale de l'outil suivant la morphologie ou la taille de l'utilisateur. Après pénétration des fourches de la fourche-bêche, et sa mise en contact avec le sol , ce dispositif articulé forme un point d'appui plus adapté et efficace du levier qui, sous l'effet de la force exercée sur le manche de l'outil, permet de retourner facilement le contenu de la fourche-bêche. I1 comprises, according to a first characteristic, a piece adjustable in height in the shape of a U. The horizontal part of this large profile on the surface is designed to be in contact with the ground Fixed on the external upper part of the tool on which we will have provided bosses drilled with holes, it is integral with the spade fork and articulated by means of an axis. The vertical parts of the device have holes located at different altitudes and placed above its center of gravity. Thus allowing and depending on the chosen position to adapt the ideal height of the tool according to the morphology or size of the user. After penetration of the forks of the fork-spade, and its contact with the ground, this articulated device forms a more suitable and effective fulcrum of the lever which, under the effect of the force exerted on the handle of the tool, allows you to easily turn the contents of the spade fork.
Selon des modes particuliers de réalisations:
- La partie horizontale du dispositif peut comporter des trous situés à différentes altitudes au dessus de son centre de gravité et permettre ainsi suivant la position choisie d'adapter la hauteur de l'outil suivant la morphologie de l'utilisateur.According to particular embodiments:
- The horizontal part of the device may include holes located at different altitudes above its center of gravity and thus allow, depending on the chosen position, to adapt the height of the tool according to the morphology of the user.
- Le dispositif peut comporter un axe permettant son articulation avec l'outil. - The device may include an axis allowing its articulation with the tool.
-La fourche-bêche peut comporter des bossages percés afin de recevoir l'axe. -The spade fork can include bosses drilled to receive the axle.
Les dessins annexés illustrent l'invention. The accompanying drawings illustrate the invention.
- La figure 1 représente le dispositif fixé sur la fourche- bêche. - Figure 1 shows the device attached to the fork.
- La figure 2 représente le dispositif avec son axe monté. - Figure 2 shows the device with its axis mounted.
- La figure 3 représente le dispositif et l'outil en fonctionnement avec son
chargement.- Figure 3 shows the device and the tool in operation with its
loading.
En référence à la figure 1 le dispositif se compose d'une pièce en
forme de U Oi fixée et articulée à la fourche- bêche par l'intermédiaire
d'un axe 02. Celui-ci comporte à chaque extrémité une gorge prévue pour
recevoir un clip 0 . Les parties verticales du profilé comportent des trous (i) traversés par l'axe et situés au dessus de son centre de gravité
permettant à l'articulation par inertie et suivant n'importe position d'être
parallèle au sol . La fourche- bêche comportera des bossages moulés 05
percés eux aussi de trous pour recevoir le même axe
Le dispositif selon l'invention est particulièrement destiné à
augmenter l'efficacité et le rendement d'une fourche- bêche avec un
fonctionnement plus aisé et plus spécialement pour des travaux sur les
sols mous On peut également l'utiliser pour arracher de l'herbe. Referring to Figure 1 the device consists of a piece in
U Oi shape fixed and articulated to the spade fork through
an axis 02. This has at each end a groove provided for
receive a clip 0. The vertical parts of the profile have holes (i) crossed by the axis and located above its center of gravity
allowing the joint by inertia and in any position to be
parallel to the ground. The spade fork will have molded bosses 05
also drilled holes to receive the same axis
The device according to the invention is particularly intended for
increase the efficiency and output of a spade fork with a
easier to operate and more specifically for work on
soft soil It can also be used to pull up grass.
