Description

OUTIL MANUEL POUR COUPER ET RECOLTER
DES PRODUITS A TIGE CORIACE
La présente invention concerne un outil manuel pour couper et récolter les produits agricoles à tige coriace, notamment les fruits tels que par exemple les raisins, comportant une poignée constituée de deux branches articulees l'une par rapport à l'autre et portant des organes complémentaires de coupe ainsi que des moyens pour pincer et maintenir le fruit par sa tige lorsque cette dernière a été coupée par les organes de coupe, selon la revendication du brevet principal.MANUAL TOOL FOR CUTTING AND HARVESTING
PRODUCTS WITH CORIACEOUS STEM
The present invention relates to a manual tool for cutting and harvesting agricultural products with a tough stem, in particular fruit such as, for example, grapes, comprising a handle consisting of two branches articulated with respect to each other and carrying complementary members. cutting and means for pinching and holding the fruit by its stem when the latter has been cut by the cutting members, according to claim of the main patent.

L'outil selon le brevet principal comporte une lame dont la ligne de coupe est sensiblement parallèle à la surface inférieure du bec supérieur de l'outil. De cette manière, notamment lorsque l'utilisateur coupe des tiges de relativement faible diametre, les tiges sont entierement coupes avant que les surfaces de pincement des becs n'entrent en action. Il en résulte que l'outil ne remplit qu'incomplètement sa double fonction qui consiste à la fois à couper les tiges et retenir par pincement cette tige entre les deux becs de l'outil.The tool according to the main patent comprises a blade whose cutting line is substantially parallel to the lower surface of the upper spout of the tool. In this way, especially when the user cuts rods of relatively small diameter, the rods are completely cut before the gripping surfaces of the nozzles come into action. As a result, the tool only partially fulfills its double function which consists in both cutting the rods and pinching this rod between the two nozzles of the tool.

La présente invention se propose de pallier cet inconvénient en rea- lisant un outil grâce auquel l'opérateur peut retenir le fruit par sa tige, quel que soit le diamètre de celle-ci, lorsqu'elle a été coupée.The present invention proposes to overcome this drawback by using a tool by which the operator can retain the fruit by its stem, whatever the diameter thereof, when it has been cut.

Dans ce but, cet outil est caractérisé en ce que les organes de coupe comportent une lame amovible attachée au bec supérieur solidaire de 1' une des branches de la poignée et disposée de telle manière que la ligne de coupe de la lame forme un angle aigu avec la surface inférieure dudit bec supérieur.For this purpose, this tool is characterized in that the cutting members comprise a removable blade attached to the upper beak secured to one of the branches of the handle and arranged in such a way that the cutting line of the blade forms an acute angle with the lower surface of said upper spout.

Selon un mode de réalisation préféré, quelle que soit la position relative des becs solidaires des branches de la poigne, la distance entre les surfaces de pincement, en fin de course des deux becs est toujours supérieure à la distance entre la ligne de coupe de la lame et la surface inférieure du bec supérieur.According to a preferred embodiment, whatever the relative position of the spouts integral with the arms of the handle, the distance between the nipping surfaces, at the end of the travel of the two spouts is always greater than the distance between the cutting line of the blade and the lower surface of the upper beak.

Par ce moyen, quelle que soit l'épaisseur de la tige du fruit à couper, à condition que cette tige soit engagée au fond de l'ouverture de 1' outil, les surfaces de pincement des deux becs entrent en fonction pour pincer cette tige et retenir le fruit, avant que la lame ait terminé de sectionner complètement cette tige.By this means, whatever the thickness of the stem of the fruit to be cut, provided that this stem is engaged at the bottom of the opening of the tool, the gripping surfaces of the two nozzles come into operation to pinch this stem and retain the fruit, before the blade has finished severing this stem completely.

Ceci correspond au but recherché quel que soit le diamètre de la tige à couper.This corresponds to the desired goal regardless of the diameter of the rod to be cut.

Pour assurer une meilleure préhension de la tige du fruit, l'une au moins des surfaces de pincement de l'un des becs solidaires des branches de la poignée est dentée.To ensure better grip of the fruit stem, at least one of the nip surfaces of one of the spouts secured to the branches of the handle is toothed.

En outre, l'axe d'articulation des deux branches de la poignée a eté déplace vers la pointe des becs de l'outil, par rapport à la position qu'il occupait dans l'outil selon le brevet principal. Ceci permet de définir une ouverture limite de ce bec, ouverture correspondant sensiblement au diamètre de la tige la plus épaisse que l'on envisage de couper avec cet outil.In addition, the axis of articulation of the two branches of the handle has been moved towards the tip of the spouts of the tool, relative to the position it occupied in the tool according to the main patent. This makes it possible to define a limit opening of this spout, an opening corresponding substantially to the diameter of the thickest rod which it is intended to cut with this tool.

La présente invention sera mieux comprise en référence à la description d'un exemple de realisation et du dessin annexé dans lequel
La figure 1 est une vue en élévation de l'outil selon l'invention,
La figure 2 est une vue de face de l'outil de la fig. 1, et
Les figures 3 et 4 sont des vues partielles en coupe illustrant le fonctionnement de l'outil selon l'invention.The present invention will be better understood with reference to the description of an exemplary embodiment and the attached drawing in which
FIG. 1 is an elevation view of the tool according to the invention,
FIG. 2 is a front view of the tool of FIG. 1, and
Figures 3 and 4 are partial sectional views illustrating the operation of the tool according to the invention.

En référence aux figures, l'outil selon l'invention comporte une poignée 30 constituée par deux branches 31 et 32 articulées autour d'un axe de pivotement 33 matérialisé apr un bouchon dont l'extrémité filetée porte un écrou de blocage 34. Cet axe a eté décalé vers l'avant des becs 35 et 36, respectivement solidaires des branches 31 et 32 de la poignée 30, par rapport à la position qu'il occupait sur l'outil du brevet principal. Ceci permet d'assurer une ouverture limite des becs 35 et 36, ouverture obtenue (comme le montre la figure 1), lors que la surface 37 de la branche 32 est en appui contre la surface 38 en regard du bec 35 relié à la branche 31 au moyen de deux rivets 39 et 40.L'angle d'ouverture des becs 35 et 36 étant limité, l'opérateur n a plus d'efforts à faire, comme c'était le cas avec l'outil du brevet principal, pour limiter l'écartement des branches 31 et 32 de la poignée 30. Ceci est avantageux parce qu'il se fatigue moins et n'aura à vaincre la résistance du ressort 41 que pendant la phase de coupe.With reference to the figures, the tool according to the invention comprises a handle 30 constituted by two branches 31 and 32 articulated around a pivot axis 33 materialized after a plug whose threaded end carries a locking nut 34. This axis was shifted forward of the spouts 35 and 36, respectively integral with the branches 31 and 32 of the handle 30, relative to the position it occupied on the main patent tool. This ensures a limit opening of the spouts 35 and 36, opening obtained (as shown in Figure 1), when the surface 37 of the branch 32 is in abutment against the surface 38 opposite the spout 35 connected to the branch 31 by means of two rivets 39 and 40. The angle of opening of the spouts 35 and 36 being limited, the operator no longer has to make efforts, as was the case with the tool of the main patent, to limit the spacing of the branches 31 and 32 of the handle 30. This is advantageous because it tires less and will only have to overcome the resistance of the spring 41 during the cutting phase.

Par ailleurs, comme le montrent les figures 1 et 2, la surface de pincement 42 du bec inferieur 36 est dentée. I1 est bien entendu que la surface de pincement 43 du bec supérieur 35 pourrait être dentee en remplacement de la surface 42 ou les-deux surfaces 42 et 43 pourraient être dentees conjointement.Furthermore, as shown in Figures 1 and 2, the gripping surface 42 of the lower spout 36 is toothed. It is understood that the gripping surface 43 of the upper spout 35 could be toothed to replace the surface 42 or the two surfaces 42 and 43 could be toothed together.

Un des avantages les plus importants de cet outil réside dans le fait que la lame 44 fixée de façon amovible au bec 35, par l'intermédiaire de deux vis 45, présente une ligne ou un bord de coupe 46 qui forme un angle aigu par rapport à la surface de pincement 43 du bec supérieur 35. Si en outre, la distance entre les surfaces de pincement, en fin de course reste légèrement supérieure à la profondeur de coupe de la lame, la tige est pincée avant d'être entièrement coupée, comme le montrent les figures 3 et 4. En admettant que le terme "fin de course" s'applique à la position des surfaces ou mâchoires de pincement lorsqu'elles sont en appui contre la tige, sans toutefois la- comprimer, si l'écartement des surfaces de pincement en fin de course, qui est en fait égal à l'épaisseur de la tige, est supérieur à la distance entre la ligne de coupe 46 et la surface 43, la tige sera pincée avant d'être coupée. Ceci signifie que pour couper complètement la tige, il faudra resserrer les becs 35 et36 de telle maniere que les surfaces de pincement compriment légèrement la tige, comme le montre nettement la figure 4.One of the most important advantages of this tool resides in the fact that the blade 44 removably fixed to the spout 35, by means of two screws 45, has a line or a cutting edge 46 which forms an acute angle with respect to to the nipping surface 43 of the upper spout 35. If, in addition, the distance between the nipping surfaces, at the end of the stroke remains slightly greater than the cutting depth of the blade, the rod is nipped before being completely cut, as shown in Figures 3 and 4. Assuming that the term "limit switch" applies to the position of the gripping surfaces or jaws when they are pressed against the rod, without however compressing it, if the spacing of the pinching surfaces at the end of the stroke, which is in fact equal to the thickness of the rod, is greater than the distance between the cutting line 46 and the surface 43, the rod will be pinched before being cut. This means that to completely cut the rod, it will be necessary to tighten the nozzles 35 and 36 in such a way that the pinching surfaces slightly compress the rod, as clearly shown in FIG. 4.

Il est bien entendu que cet outil peut présenter différentes modifications et être réalisé sous différentes variantes évidentes pour 1 'hom- me de l'art. It is understood that this tool can have different modifications and be produced in different variants obvious to one skilled in the art.
