Abstract

The knife, for cutting foodstuffs into slices of a controlled thickness, has the handle (2) equipped with a thickened portion (2a) adjacent to its joint, with the blade which contains a square aperture for the support (3) of a plate (4). The plate is equipped with a side rim (4a) which controls the thickness of the slice of food cut by the knife blade. The plate is equipped with a bush (4b) which is able to pivot about a cylindrical projection (5b) connected to the support. The support can be inserted into either side of the handle for right- or left-handed use, and the thickness regulator is interchangeable to provide for slices of different thickness.

Description

La présente invention concerne un couteau équipé d'un dispositif interchangeable pour régler à volonté l'épaisseur de l'aliment que l'on doit couper, offrant la possibilité de remplacer ledit dispositif par un autre identique de façon spéculaire, de manière à pouvoir saisir le manche du couteau soit de la main droite soit de la main gauche.The present invention relates to a knife equipped with an interchangeable device for adjusting the thickness of the food to be cut at will, offering the possibility of replacing said device with another identical specularly, so as to be able to grasp the knife handle either with the right hand or with the left hand.

Tout en considérant toujours la même main qui saisit le couteau, le renversement du dispositif de réglage par rapport à la lame devient tout à fait nécessaire au cas où la lame se présenterait, comme il arrive souvent, avec un double aiguisage, à la denture de forme différente permettant de couper des produits alimentaires de genre et de consistance différents.While always considering the same hand which grasps the knife, the reversal of the adjusting device with respect to the blade becomes absolutely necessary in the event that the blade presents itself, as often happens, with a double sharpening, to the teeth of different shape for cutting food products of different kinds and consistency.

Actuellement, on connaît déjà des couteauxéquipés du dispositif de ré glage équivalents, mais de tels couteaux présentent une formulation de construction qui en empêche un usage universel, c'est à dire que lesdits couteaux sont de façon univoque doitiers ou gauchers, sans aucune possibilité d'interchanger le dispositif,ni de le renverser, c'est pourquoi on ne peut même pas monter des lames à deux tranchants.Currently, knives are already known equipped with the equivalent adjustment device, but such knives have a construction formulation which prevents their universal use, that is to say that said knives are unequivocally right-handed or left-handed, without any possibility of 'Interchanging the device, or overturning it, that's why you can't even mount double-edged blades.

Le couteau selon notre invention utilise une lame dont un morceau est enfoncé dans le manche, moulé en matière plastique, caractérisé par un épaississement prismatique transversal, percé axialement, en correspondance de la zone de jonction de la lame, qui se trouve sur un plan de symétrie longitudinale du manche.The knife according to our invention uses a blade, a piece of which is pressed into the handle, molded in plastic material, characterized by a transverse prismatic thickening, pierced axially, in correspondence with the junction zone of the blade, which lies on a plane of longitudinal symmetry of the handle.

Dans le trou du corps prismatique susdit on peut introduire, soit de soit de la gauche, la droite,/avec l'arrêt par forçage de fin de course, un étui de support de la tablette, profilée convenablement, contre laquelle on pose l'aliment que l'on doit couper en tranches et qui fléchit élastiquement, en pivotant vers le haut, quand la lame touche sur le plan où se trouve le produit alimentaire, à la fin de chaque tranche.In the hole of the aforementioned prismatic body one can introduce either either from the left, the right, / with the stop by forcing at the end of the stroke, a tablet support case, suitably profiled, against which the food is placed which must be cut into slices and which bends elastically , pivoting upwards, when the blade touches the plane where the food product is located, at the end of each slice.

La susdite tablette déborde, à la partie frontale, d'un tourillon transversal qui peut pivoter et défiler dans un trou axial obtenu spécialement dans l'étui de support susdit, puisque l'on a prévu une vis de réglage qui permet de faire coulisser ledit tourillon à l'inté rieur de son logement, en déplaçant solidairement la tablette et en réglant conséquemment sa distance de la lame et donc l'épaisseur de la tranche.The aforesaid shelf overflows, at the front, with a transverse pin which can pivot and slide in an axial hole obtained specially in the aforementioned support case, since an adjustment screw has been provided which makes it possible to slide the said pin inside its housing, by moving the tablet securely and consequently adjusting its distance from the blade and therefore the thickness of the wafer.

Pour une plus claire explication de l'invention, la description continue en référence aux dessins ci-annexés qui ne sont donnés qu'à titre d'exemple illustratif, non limitatif, et où:

  • - la fig. 1 est une représentation axonométrique du couteau selon l'invention avec le dispositif de réglage monté pour une prise droitière)

En référence aux figures sudites, le couteau en question comporte une lame (1), à deux tranchants, enfoncée à l'une de ses extrémités dans le manche (2), qui présente, en correspondance de la zone de jonction de la lame, un épaississement (2a), allongé transversalement, comportant un trou de passage (2b) de section carrée, où est logé l'étui prismatique (3) de support pour la tablette (4) équipée, à la partie inférieure, d'un rebord latéral (4a) contre lequel on appuve l'aliment que l'on doit couper en tranches.With reference to the Sudite figures, the knife in question comprises a blade (1), with two cutting edges, inserted at one of its ends in the handle (2), which has, in correspondence with the junction zone of the blade, a thickening (2a), elongated transversely, comprising a passage hole (2b) of square section, where is housed the prismatic case (3) for supporting the tablet (4) equipped, at the bottom, with a rim side (4a) against which the food is pressed which must be cut into slices.

Ladite tablette (4) déborde à la partie frontale d'un tourillon transversal (4b), tiré d'un seul morceau moulé en plastique avec la susdite tablette, puisque ledit tourillon (4b) ira s'insérer partiellemnt dans le trou borgne (3a) prévu à l'une des extrémités de l'étui de support (3).Said shelf (4) projects beyond the front part of a transverse journal (4b), drawn from a single piece molded in plastic with the above-mentioned shelf, since said pin (4b) will be inserted partially into the blind hole (3a) provided at one end of the support case (3).

Le tourillon (4b), creux, peut pivoter librement à l'intérieur du trou (3a) de l'étui (3), où il est maintenu par une vis, dont la tige (5a) traverse axialement le tourillon (4b) et se visse à l'intérieur d'un tube (6), taraudé à l'interieur, enfoncé partiellement sur le fond du trou (3a) puisque J 'on a prévu un ressort hélicoidal cylindrique (7), introduit dans le même trou (3a) et dans le tourillon (4b) et qui exerce constamment une poussée sur le tourillon qui tend à l'expulser de l'étui (3).The hollow pin (4b) can pivot freely inside the hole (3a) of the case (3), where it is held by a screw, the rod (5a) of which axially crosses the pin (4b) and is screwed inside a tube (6), internally threaded, partially pressed into the bottom of the hole (3a) since I have provided a cylindrical helical spring (7), introduced into the same hole ( 3a) and in the pin (4b) and which constantly exerts a thrust on the pin which tends to expel it from the case (3).

Il est évident que, si l'on visse dans un sens ou dans l'autre la vis susdite en intervenant sur sa tête avec pommeau (5b), on peut faire défiler le tourillon (4b) dans l'étui (3) et par conséquent on peut régler la distance entre la paroi latérale (4a) de la tablette (4) et la lame (1).It is obvious that, if one screws in one direction or the other the aforementioned screw by intervening on his head with knob (5b), one can scroll the pin (4b) in the case (3) and by therefore, the distance between the side wall (4a) of the shelf (4) and the blade (1) can be adjusted.

Au but d'obtenir un affaissement élastique de la tablette (4) à la fin de chaque tranche, au moment où la lame (1) va toucher le plan d'appui du produit coupé, la tablette (4) présente, à la partie postérieure, une entaillure longitudinale (4c) dans laquelle est encastrée une pat te élastique (4d) adressée vers le manche et inclinée vers le haut par rapport au plan de la tablette (4).In order to obtain an elastic collapse of the tablet (4) at the end of each section, when the blade (1) will touch the plane of support of the cut product, the tablet (4) has, at the part posterior, a longitudinal notch (4c) in which is embedded an elastic tab (4d) addressed towards the handle and inclined upward relative to the plane of the shelf (4).

Ladite patte (4d) termine par une petite tête plate (4e), aux coins ar rondis, qui s'aboute au-dessous et dans l'angle raccordé (8) formé, sur la paroi frontale du corps (2a) du manche (2), par une nervure longitu dinale médiane (2c) de section svmétrique.Said tab (4d) ends with a small flat head (4e), with rounded ar corners, which abuts below and in the connected angle (8) formed, on the front wall of the body (2a) of the handle ( 2), by a median longitu dinal rib (2c) of svmetric section.

Lors du renversement vers le haut de la tablette (4), qui comporte la rotation conséquente du tourillon (4b) à l'intérieur de l'étui (3), la patte encastrée (4d) fléchit élastiquement en bas à cause du contraste et de l'arrêt de la tête d'extrémité (4e) sous la nervure (2c), dans l'angle (8) susdit.During the upward tilting of the tablet (4), which involves the consequent rotation of the pin (4b) inside the case (3), the recessed tab (4d) flexes elastically downwards due to the contrast and from the stop of the end head (4e) under the rib (2c), in the angle (8) above.

Une fois que l'on a terminé de couper, le retour Elastique de la patte (4d) reporte la tablette (4) à sa juste position de repos et c'est à dire avec son rebord latéral (4a) au-dessous du tranchant inférieur de la lame (1).Once you have finished cutting, the elastic return of the tab (4d) transfers the tablet (4) to its correct rest position and that is to say with its lateral edge (4a) below the lower edge of the blade (1).

Comme nous avons déjà esquissé dans l'introduction, le dispositif de réglage selon l'invention permet d'être utilisé sur des couteaux aux lames à deux tranchants, puisqu'il est suffisant, dans ce cas, d'enle ver l'étai (3) du manche (2) et de l'introduire de nouveau de l'autre côté, après avoir retourné le couteau.As we have already outlined in the introduction, the adjustment device according to the invention makes it possible to be used on knives with blades with two cutting edges, since it is sufficient, in this case, to remove the prop ( 3) from the handle (2) and insert it again on the other side, after turning the knife over.

En outre, si l'on équipe le couteau de deux dispositifs de réglage, identiques de façon spéculaire, on pourra appliquer sur le même couteau un dispositif ou l'autre alternativement suivant que la prise soit faite de la main gauche ou de la main droite.In addition, if one equips the knife with two adjustment devices, identical in a specular manner, one can apply on the same knife one device or the other alternately depending on whether the grip is made with the left hand or the right hand. .
