Abstract

Multi blade cutter consists of a peripheral frame, which carries a series of parallel blades (1). Each blade extends between two cross beams (5, 6) of the frame and to which the blades are attached at their ends. At least one (6) of the cross beams is elastically deformable and presents, at rest, link points with the blades separated along the length of a curve (6a), with the concave side towards the other beam. The frame is completed at each end by two keepers (7, 8) which are forced between the cross beams, to straighten the curve.

Description

La présente invention concerne un organe de coupe multi-lame destiné particulièrement à la découpe en tranches de denrées alimentaires telles que des légumes ou des fruits. The present invention relates to a multi-blade cutting member intended in particular for slicing foodstuffs such as vegetables or fruits.

I1 existe des appareils ménagers ou destinés à la préparation industrielle de mets dont la fonction est de réaliser la coupe en tranches d'un produit comestible, ces tranches pouvant être utilisées comme telles ou recoupées en bâtonnets par une découpe subséquente à la première. I1 exist household appliances or intended for the industrial preparation of dishes whose function is to carry out the slicing of an edible product, these slices being able to be used as such or cut into sticks by a cutting subsequent to the first.

Lorsqu'il s'agit d'appareils domestiques manuels ou électriques, l'usage relativement peu intensif de ceux-ci permet de pouvoir s'accommoder de certains défauts dans les outils mis en oeuvre, et notamment d'une tension inégale et imparfaite des lames de coupe. When it comes to manual or electric domestic appliances, the relatively low intensity of these makes it possible to be able to accommodate certain faults in the tools used, and in particular of an uneven and imperfect tension of the cutting blades.

En revanche dans le cas d'appareils de cuisine destinés soit à des collectivités soit à la préparation industrielle des mets, il convient de disposer d'outils plus performants et se pose alors la question d'une fabrication soignée sans laquelle les outils se dégradent rapidement. Aucune technique de fabrication n'est aujourd'hui satisfaisante pour obtenir un bon résultat. C'est ainsi qu'une méthode consistant à maintenir les lames tendues dans un moule de surmoulage du bâti en matière plastique n'a pas permis d'obtenir un outil de coupe satisfaisant. On the other hand in the case of kitchen appliances intended either for communities or for the industrial preparation of dishes, it is necessary to have more efficient tools and the question then arises of a careful manufacturing without which the tools degrade quickly . No manufacturing technique is satisfactory today to obtain a good result. Thus, a method consisting in keeping the blades stretched in a mold for overmolding the plastic frame did not make it possible to obtain a satisfactory cutting tool.

L'invention est une solution à ce problème mal résolu qui permet l'obtention d'outils de coupe multi-lame de qualité satisfaisante et durable. The invention is a solution to this poorly resolved problem which makes it possible to obtain multi-blade cutting tools of satisfactory and lasting quality.

Elle a pour objet un organe de coupe multi-lame comportant un bâti périphérique dans lequel est montée une pluralité de lames parallèles, chaque lame s'étendant entre deux traverses du bâti auquel elle est reliée par ses deux extrémités. Dans l'invention, au moins une traverse et élastiquement déformable et présente au repos des points de liaison avec les lames répartis le long d'une courbe dont la concavité est tournée du côté de l'autre traverse tandis que le bâti comprend de part et d'autre de la pluralité de lames une entretoise engagée à force entre les traverses en tendant à redresser la courbe susdite. It relates to a multi-blade cutting member comprising a peripheral frame in which is mounted a plurality of parallel blades, each blade extending between two cross members of the frame to which it is connected by its two ends. In the invention, at least one cross member which is elastically deformable and which, at rest, has connection points with the blades distributed along a curve whose concavity is turned towards the side of the other cross member while the frame comprises on the one hand and on the other, from the plurality of blades, a spacer force-fitted between the crosspieces, tending to straighten the above curve.

Dans un mode particulier de réalisation, chaque lame est pourvue d'une lumière à chacune de ses extrémités, la distance séparant les extrémités des lumières les plus extérieures est constante d'une lame à l'autre et chacune des traverses est formée par une plaque courbe glissée dans une lumière d'extrémité de chaque lame de manière que son bord convexe soit redressé pour porter contre l'extrémité extérieure de la lumière de chaque lame lorsque les entretoises sont mises en place. In a particular embodiment, each blade is provided with a light at each of its ends, the distance separating the ends of the outermost lights is constant from one blade to the other and each of the crosspieces is formed by a plate curve slid into an end lumen of each blade so that its convex edge is straightened to bear against the outer end of the lumen of each blade when the spacers are in place.

Enfin, dans l'organe selon l'invention, les traverses et les entretoises une fois mises en place avec ses lames, sont revêtues d'une matière plastique par surmoulage. Finally, in the member according to the invention, the crosspieces and the spacers once put in place with its blades, are coated with a plastic material by overmolding.

D'autres caractéristiques et avantages de l'invention ressortiront de la description d'un mode de réalisation particulier de l'invention donné ci-après à titre d'exemple. Other characteristics and advantages of the invention will emerge from the description of a particular embodiment of the invention given below by way of example.

I1 sera fait référence aux dessins annexés parmi lesquels - la figure 1 est un schéma qui illustre les composants de l'outil selon l'invention dans leur état non assemblé, - la figure 2 est un schéma de cet outil, les composants étant assemblés, - la figure 3 est une représentation d'une traverse mise industriellement en oeuvre, - la figure 4 est une vue en plan de l'outil selon l'invention complètement réalisée avec le surmoulage du bâti périphérique par une matière plastique. Reference will be made to the appended drawings, in which - FIG. 1 is a diagram which illustrates the components of the tool according to the invention in their unassembled state, - FIG. 2 is a diagram of this tool, the components being assembled, - Figure 3 is a representation of a crosspiece industrially used, - Figure 4 is a plan view of the tool according to the invention completely produced with the overmolding of the peripheral frame by a plastic material.

A la figure 1, les lignes parallèles 1 représentent des lames vues en coupe faisant apparaître à chacune de leurs extrémités une lumière 2a et 2b. Dans l'exemple représenté, on a désigné par d la distance qui sépare les bords extrêmes les plus éloignés des lumières 2a et 2b de chaque lame. Cette distance d est commune à toutes les lames. L'extrémité extérieure de la lumière 2a est notée 3 et l'extrémité extérieure de la lumière 2b est notée 4. In FIG. 1, the parallel lines 1 represent blades seen in section showing at each of their ends a lumen 2a and 2b. In the example shown, d is designated by the distance which separates the most distant extreme edges of the slots 2a and 2b of each blade. This distance d is common to all the blades. The outer end of the light 2a is denoted 3 and the outer end of the light 2b is denoted 4.

Une traverse 5 est glissée dans toutes les lumières 2b pour s'appuyer sur les extrémités 4 de chacune des lames. Cette traverse 5 est en un matériau qui n'est pas déformable pour les besoins de l'explication, mais ceci n'est pas limitatif. Une traverse 6 est logée quant à elle dans les lumières 2a. Cette traverse est en forme d'un arc de cercle, c'est-à-dire que son bord convexe 6a qui est celui qui au final va porter contre les extrémités 3 des lumières 2a forme une courbe dont la concavité est tournée vers la traverse 5. En d'autres termes les points de liaison de la traverse 6 avec les lames 1 qui seront les points de contact de cette traverse avec les extrémités 3 de lumières 2a sont, lorsque la traverse est au repos, le long d'une courbe dont la concavité est tournée vers la traverse opposée. A cross 5 is slid into all of the slots 2b to rest on the ends 4 of each of the blades. This cross-member 5 is made of a material which is not deformable for the purposes of the explanation, but this is not limiting. A cross 6 is housed in turn in the lights 2a. This cross is in the form of an arc of a circle, that is to say that its convex edge 6a which is the one which will ultimately bear against the ends 3 of the lights 2a forms a curve whose concavity is turned towards the cross 5. In other words, the points of connection of the cross-member 6 with the blades 1 which will be the points of contact of this cross-member with the ends 3 of slots 2a are, when the cross-member is at rest, along a curve whose concavity is turned towards the opposite cross-member.

A la figure 1 on a également représenté deux entretoises 7 et 8 qui vont constituer avec les traverses 5 et 6, le bâti périphérique de maintien avec les lames 1. Chaque entretoise est en forme de tige présentant à chacune de ses extrémités une gorge 9 et 10 de sorte que chaque extrémité puisse recevoir les extrémités des entretoises 5 et 6. La distance dl qui sépare le fond des gorges 9 et 10 est au moins égale à la distance d séparant les bords 3 et 4 des lumières de chaque lame diminuée de la valeur des deux largeurs el et e2 des traverses 5, 6, et de préférence légèrement supérieure à cette dimension d - (el + e2). FIG. 1 also shows two spacers 7 and 8 which will constitute, with the crosspieces 5 and 6, the peripheral support frame with the blades 1. Each spacer is in the form of a rod having at each of its ends a groove 9 and 10 so that each end can receive the ends of the spacers 5 and 6. The distance dl which separates the bottom of the grooves 9 and 10 is at least equal to the distance d separating the edges 3 and 4 of the lumens of each strip minus the value of the two widths el and e2 of the crosspieces 5, 6, and preferably slightly greater than this dimension d - (el + e2).

A la figure 2 on a représenté l'outil avec son bâti monté et on remarque qu'ayant introduit en force entre les extrémités des traverses 5, 6 les entretoises 7, 8, on a provoqué un redressement de l'entretoise 6 qui, déformable élastiquement, prend appui sur l'extrémité 3 des lumières 2a de chaque lame 1. Avec une différence entre (dl + el + e2) et d de l'ordre du dixième de millimètre, on s'est rendu compte qu'on assurait une tension régulière et équilibrée de chacune des lames 1 de l'outil. In Figure 2 there is shown the tool with its frame mounted and it is noted that having introduced in force between the ends of the crosspieces 5, 6 the spacers 7, 8, it caused a straightening of the spacer 6 which, deformable elastically, rests on the end 3 of the lights 2a of each blade 1. With a difference between (dl + el + e2) and d of the order of a tenth of a millimeter, we realized that we were ensuring a regular and balanced tension of each of the blades 1 of the tool.

La figure 3 illustre la forme réelle d'une traverse 11 telle qu'elle est mise en oeuvre industriellement dans l'invention. Cette traverse se présente sous la forme d'une lame en acier ressort courbe ayant une flèche de l'ordre du millimètre et dont les extrémités présentent des chanfreins 12 et 13 avant un épaulement 14, 15 contre lequel sera appuyée chacune des entretoises 7 et 8. Les chanfreins 12 et 13 permettent de faciliter la mise en place en force des entretoises 7 et 8 au moyen d'un outillage de montage tel qu'un vérin pneumatique. Contrairement aux figures 1 et 2, dans la réalisation industrielle de l'invention, on utilise deux traverses 11 placées de manière que leur concavité se fasse face. FIG. 3 illustrates the actual shape of a cross member 11 as it is used industrially in the invention. This crosspiece is in the form of a curved spring steel blade having an arrow of the order of a millimeter and the ends of which have chamfers 12 and 13 before a shoulder 14, 15 against which each of the spacers 7 and 8 will be supported. The chamfers 12 and 13 make it easier to force the spacers 7 and 8 into place by means of mounting tools such as a pneumatic cylinder. Unlike Figures 1 and 2, in the industrial embodiment of the invention, two cross members 11 are used so that their concavity faces each other.

A la figure 4 enfin, on a représenté par une vue de dessus l'aspect de l'outil multi-lame selon l'invention dans lequel le bâti formé des traverses 11 et des entretoises 7 et 8 est surmoulé par injection d'une matière plastique 16 du genre polyamide.Finally, in FIG. 4, a top view shows the appearance of the multi-blade tool according to the invention in which the frame formed by crosspieces 11 and spacers 7 and 8 is overmolded by injection of a material. plastic 16 of the polyamide type.
