Description

MANCHE D'OUTIL COUPANT CUTTING TOOL HANDLE
L'invention a trait à un manche d'outil coupant. De tels outils coupants, notamment des couteaux, sont utilisés dans des industries agroalimentaires, par exemple pour effectuer des opérations de découpe de produits carnés ou de poissons. Lors de ces opérations, la prise en main du couteau doit être sûre pour éviter tout risque de blessure de l'utilisateur. La main tenant le couteau est fréquemment équipée d'un gant fabriqué en un matériau résistant aux coupures et isolant, ces opérations de découpe devant avoir lieu dans des salles réfrigérées. Compte tenu de la nature des produits travaillés, les outils et les mains, gantées ou non, de l'utilisateur sont rapidement imprégnés de matière grasse. La présence de gras sur le manche du couteau et/ou le gant ou la main nuit à la tenue du couteau, ce qui favorise le risque de perte et/ou de dérapage de l'outil, et donc augmente le risque de blessures.The invention relates to a cutting tool handle. Such cutting tools, in particular knives, are used in food processing industries, for example to carry out cutting operations of meat products or fish. During these operations, the grip of the knife must be safe to avoid any risk of injury to the user. The hand holding the knife is frequently equipped with a glove made of a material resistant to cuts and insulation, these cutting operations to take place in refrigerated rooms. Given the nature of the products worked, the tools and hands, gloved or not, the user are quickly impregnated with fat. The presence of grease on the handle of the knife and / or glove or hand impairs the holding of the knife, which promotes the risk of loss and / or skidding of the tool, and thus increases the risk of injury.
Pour remédier à cela, on connaît un type de manche réalisé dans un matériau à fort pouvoir d'adhésion. On connaît également un autre type de manche pourvu de nombreuses excroissances adjacentes pour améliorer Ia tenue du couteau. Néanmoins, lors de l'utilisation, une pellicule grasse se forme sur les excroissances, ce qui diminue son adhérence et diminue la nettoyabilité du manche. Par ailleurs, les excroissances présentes sur ce type de manche sont relativement rigides, ce qui entraîne une gêne et un inconfort et ne favorise pas la prise en main. On connaît par WO-A-0147682 un manche de couteau équipé de reliefs en forme de bouton arrondi. US-A-5528834 décrit un manche de couteau en caoutchouc pourvu de picots.To remedy this, we know a type of handle made of a high adhesion material material. There is also known another type of handle provided with numerous adjacent growths to improve the holding of the knife. Nevertheless, during use, a greasy film is formed on the growths, which reduces its adhesion and decreases the cleanability of the handle. Moreover, the excrescences present on this type of handle are relatively rigid, which causes discomfort and discomfort and does not promote handling. WO-A-0147682 discloses a knife handle equipped with reliefs in the shape of a rounded button. US-A-5528834 discloses a rubber knife handle provided with pins.
L'invention propose, en alternative, un manche d'outil coupant permettant une prise en main efficace, confortable et permettant de diminuer les risques de blessure, même après plusieurs heures d'utilisation du couteau en milieu gras, tout en étant aisé à nettoyer.The invention proposes, alternatively, a cutting tool handle for an effective grip, comfortable and to reduce the risk of injury, even after several hours of use of the knife in a bold medium, while being easy to clean .
A cet effet, l'invention a pour objet un manche d'outil coupant pourvu d'un dispositif favorisant la prise en main du manche par un utilisateur, ce dispositif comprenant au moins quatre reliefs disposés en un parallélogramme incliné par rapport à un axe longitudinal du manche, caractérisé en ce que les reiiefs sont sensiblement cylindriques, avec une génératrice courbe dont la concavité est tournée vers l'extérieur et en ce que la périphérie du sommet de chaque relief s'étend vers l'extérieur du corps du relief, au voisinage du sommet, de manière à former un organe d'accrochage.To this end, the subject of the invention is a cutting tool handle provided with a device that facilitates grip of the handle by a user, this device comprising at least four reliefs arranged in a parallelogram inclined with respect to a longitudinal axis. of the handle, characterized in that the reiiefs are substantially cylindrical, with a curved generatrix whose concavity is turned towards the outside and in that the periphery of the vertex of each relief extends outwardly of the body of the relief, at the near the top, so as to form a fastening member.
La présence de reliefs ainsi configurés et disposés, de facto, en quinconce entre deux rangées parallèles à un axe longitudinal du manche, permet d'obtenir une prise en main efficace. Les reliefs sont ainsi suffisamment espacés pour ne pas réaliser une surface continue et potentiellement glissante lors de la prise en main de l'outil.The presence of reliefs thus configured and arranged, de facto, staggered between two rows parallel to a longitudinal axis of the handle, provides an effective grip. The reliefs are thus sufficiently spaced apart so as not to produce a continuous and potentially slippery surface when taking up the tool.
Selon des aspects avantageux mais non obligatoires de l'invention, le manche peut incorporer une ou plusieurs des caractéristiques suivantes : -le dispositif comprend au moins deux rangées parallèles de reliefs réalisées par plusieurs parallélogrammes positionnés de manière à avoir au moins un coté mitoyen.According to advantageous but non-mandatory aspects of the invention, the handle may incorporate one or more of the following features: the device comprises at least two parallel rows of reliefs made by several parallelograms positioned so as to have at least one side adjoining.
- les reliefs d'une même rangée sont régulièrement espacés. - l'espace entre deux reliefs d'une même rangée est globalement compris entre 2 et 8 millimètres.- The reliefs of the same row are regularly spaced. - The space between two reliefs of the same row is generally between 2 and 8 millimeters.
- les reliefs occupent au moins une partie d'au moins une face du manche.- The reliefs occupy at least a portion of at least one face of the handle.
- la densité des reliefs est comprise entre 4 et 11 reliefs par centimètre carré par face du manche. - la densité des reliefs est comprise entre 6 et 8 reliefs par centimètre carré par face du manche.the density of the reliefs is between 4 and 11 reliefs per square centimeter per face of the handle. the density of the reliefs is between 6 and 8 reliefs per square centimeter per face of the handle.
- chaque relief est réalisé dans un matériau d'une dureté Shore A comprise entre 70 et 99.each relief is made of a material with a Shore A hardness between 70 and 99.
- chaque relief est réalisé dans un matériau d'une dureté Shore A comprise entre 95 et 99.each relief is made of a material with a Shore A hardness between 95 and 99.
L'invention concerne également un couteau pourvu d'un manche selon une des caractéristiques précédentes.The invention also relates to a knife provided with a handle according to one of the preceding characteristics.
L'invention sera mieux comprise et d'autres avantages de celle-ci apparaîtront plus clairement à la lecture de la description qui va suivre d'un manche conforme à l'invention, donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés dans lesquels :The invention will be better understood and other advantages thereof will appear more clearly on reading the following description of a handle according to the invention, given solely by way of example and made with reference to the following drawings in which:
- la figure 1 est une vue d'un manche d'outil coupant conforme à l'invention, une. lame étant partiellement représentée,- Figure 1 is a view of a cutting tool handle according to the invention, a. blade being partially represented,
- la figure 2 est une vue de dessus du manche de la figure 1 et - la figure 3 est une vue, à plus grande échelle, du détail ni à la figure 2.FIG. 2 is a plan view of the handle of FIG. FIG. 3 is a view, on a larger scale, of the detail or in FIG. 2.
Le manche 1 d'un couteau, représenté aux figures 1 et 2, est réalisé dans un matériau dit "de qualité alimentaire", aisé à nettoyer, inerte chimiquement et physiquement lors de son utilisation à toutes les températures rencontrées en industrie agroalimentaire. Un tel matériau est, par exemple, à base deThe handle 1 of a knife, shown in Figures 1 and 2, is made of a material called "food grade", easy to clean, chemically and physically inert during its use at all temperatures encountered in the food industry. Such a material is, for example, based on
polymères, tel que celui commercialisé sous la dénomination SARLINK® polymers, such as that marketed under the name SARLINK ®
Entre l'extrémité libre arrondie ou talon 2 du manche 1 et son extrémité ou garde 3 recevant la lame, chaque face latérale 4, 5 du manche 1 est pourvue d'une zone 6 destinée à faciliter la prise en main. Cette zone 6, de forme allongée, est positionnée globalement en partie centrale de chacune des faces 4, 5. Elle s'étend sur au moins 20 % de la surface de chaque face 4, 5. Le talon 2 et la garde 3 du manche 1 , de même que les faces inférieure 7 et supérieure 8 définissant la largeur du manche 1 , sont dépourvus du dispositif.Between the rounded free end or heel 2 of the handle 1 and its end or guard 3 receiving the blade, each side face 4, 5 of the handle 1 is provided with a zone 6 intended to facilitate handling. This zone 6, elongated, is positioned generally in the central portion of each of the faces 4, 5. It extends over at least 20% of the surface of each face 4, 5. The heel 2 and the guard 3 of the handle 1, as well as the lower 7 and upper 8 defining the width of the handle 1, are devoid of the device.
Selon un mode de réalisation non représenté, la zone 6 peut occuper l'ensemble du manche. Selon une autre variante, seule une des faces 4 ou 5 peut être pourvue d'une zone 6. Selon encore une autre variante, plusieurs zones 6 peuvent être prévues sur une ou chaque face 4 ou 5.According to an embodiment not shown, the zone 6 can occupy the entire handle. According to another variant, only one of the faces 4 or 5 may be provided with a zone 6. According to yet another variant, several zones 6 may be provided on one or each face 4 or 5.
La zone 6 comprend un fond relativement lisse réalisé dans le même matériau que le manche. Cette zone 6 comprend au moins quatre reliefs 10 disposés en un parallélogramme incliné par rapport à un axe longitudinal A-A' du manche. Ce parallélogramme est avantageusement un carré C, repéré en pointillés à la figure 1 , dont les cotés forment un angle d'environ 45° avec l'axe A-A'. En variante, les reliefs 10 sont disposés en rectangle ou en. losange et/ou l'inclinaison du parallélogramme est différente. Plusieurs carrés C de reliefs 10 sont positionnés de manière à avoir au moins un coté mitoyen et former ainsi au moins deux rangées de reliefs 10, Au moins deux rangées 9 de reliefs 10 sont disposées sur chaque zone 6 des faces 4, 5. Les reliefs 10 sont régulièrement espacés sur chaque rangée 9 qui est repérée par un trait d'axe à la figure 1. Dans l'exemple, la zone 6 visible à la figure 1 comprend cinq rangées 9 parallèles à l'axe longitudinal A-A1 du manche.Zone 6 comprises a relatively smooth bottom made of the same material as the handle. This zone 6 comprises at least four reliefs 10 arranged in a parallelogram inclined with respect to a longitudinal axis AA 'of the handle. This parallelogram is advantageously a square C, dashed in Figure 1, the sides of which form an angle of approximately 45 ° with the axis A-A '. Alternatively, the reliefs 10 are arranged in a rectangle or in. rhombus and / or the inclination of the parallelogram is different. Several squares C of reliefs 10 are positioned so as to have at least one side joint and thus form at least two rows of reliefs 10, At least two rows 9 of reliefs 10 are arranged on each zone 6 of the faces 4, 5. The reliefs 10 are regularly spaced on each row 9 which is marked with a center line in Figure 1. In the example, the area 6 visible in Figure 1 comprises five rows 9 parallel to the longitudinal axis AA 1 of the handle.
Une rangée 9 comporte au moins 5 reliefs 10 et, préférentiellement, de 8 à 12. Les reliefs 10, de facto, sont disposés, sur chaque rangée 9, en quinconce par rapport aux reliefs 10 d'au moins une rangée 9 adjacente. Ces rangées 9 adjacentes sont à considérer autant comme des rangées sensiblement parallèles à l'axe A-A' du manche que comme des rangées sensiblement perpendiculaires à cet axe. Les reliefs 10 des carrés C sont donc disposés en quinconce, que l'on considère ces reliefs dans le sens de la longueur ou de la largeur du manche 1. En d'autres termes, les reliefs 10 ne sont situés en regard les uns des autres que sur des rangées 11 , parallèles et inclinées à 45° par rapport a l'axe A-A'.A row 9 has at least 5 reliefs 10 and, preferably, 8 to 12. The reliefs 10, de facto, are arranged on each row 9, staggered relative to the reliefs 10 of at least one row 9 adjacent. These adjacent rows 9 are to be considered as rows substantially parallel to the axis A-A 'of the handle and as rows substantially perpendicular to this axis. The reliefs 10 of the squares C are thus arranged in staggered rows, that we consider these reliefs in the direction of the length or width of the handle 1. In other words, the reliefs 10 are not located opposite any of the other than on rows 11, parallel and inclined at 45 ° to the axis A-A '.
Dans l'exemple représenté, l'écart d entre les bases D de deux reliefs 10 d'une même rangée 9 ou 11 est globalement compris entre 2 et 8 millimètres. L'écart moyen entre deux rangées 9 est d'environ 3 millimètres. Les reliefs 10, visibles notamment à la figure 3, sont réalisés à partir d'un matériau souple. Ce matériau est, par exemple, à base d'élastomère, notamment du caoutchouc, d'une dureté Shore A comprise entre 70 et 99. Les reliefs 10 sont venus de matière, par exemple par moulage, avec le fond de la zone 6. Avantageusement, la dureté des reliefs 10 est comprise entre 95 et 99 shore A. Une dureté des reliefs inférieure à 70 Shore A, compte tenu des dimensions des reliefs, induit une déformation de ces derniers ne permettant pas un « accrochage » efficace lors de la prise en main. A contrario, une dureté des reliefs supérieure à 99 Shore A nuit au confort de l'utilisateur.In the example shown, the distance d between the bases D of two reliefs 10 of the same row 9 or 11 is generally between 2 and 8 millimeters. The average distance between two rows 9 is about 3 millimeters. The reliefs 10, visible in particular in Figure 3, are made from a flexible material. This material is, for example, based on an elastomer, in particular rubber, with a Shore A hardness between 70 and 99. The reliefs 10 are made of material, for example by molding, with the bottom of the zone 6. Advantageously, the hardness of the reliefs 10 is between 95 and 99 shore A. A hardness of the reliefs lower than 70 Shore A, taking into account the dimensions of the reliefs, induces a deformation of these latter not allowing an effective "hooking" during the taken in hand. On the other hand, a relief hardness greater than 99 Shore A is detrimental to the comfort of the user.
Dans un mode de réalisation non illustré, les reliefs 10 sont rapportés sur le fond de la zone 6. Ils sont alors fixés sur la zone 6 soit de manière pérenne, par exemple par collage ou soudage, soit de manière amovible, par exemple par vissage ou insertion dans des logements ménagés dans le fond de la zone 6. En variante, c'est la zone 6 munie de reliefs 10 qui est fixée, de manière pérenne ou amovible, sur un manche préalablement fabriqué.In a non-illustrated embodiment, the reliefs 10 are attached to the bottom of the zone 6. They are then fixed on the zone 6 either perennially, for example by gluing or welding, or removably, for example by screwing or insertion into housing provided in the bottom of the zone 6. Alternatively, it is the area 6 provided with reliefs 10 which is fixed permanently or removably on a handle previously manufactured.
Les reliefs 10 sont de forme cylindrique avec une génératrice courbe dont la concavité est tournée vers l'extérieur. La base 12 et le sommet 13 de chaque relief 10 sont circulaires. En variante, le sommet et/ou la base sont non circulaires, par exemple ovales. La base 12 de chaque relief a un diamètre D compris entre 1,5 et 6 millimètres, le sommet 13 ayant un diamètre compris entre 0,5 et 4 millimètres. La hauteur de chaque relief 10 est comprise entre 0,8 et 1 ,2 millimètres, avantageusement voisine de 1 millimètre. Dans l'exemple, tous les reliefs 10 sont identiques. Dans un autre mode de réalisation non . représenté, les reliefs sont différents d'une zone 6 à l'autre. Dans une variante non illustrée, ils sont également différents au sein d'une même zone 6.The reliefs 10 are of cylindrical shape with a curved generatrix whose concavity is turned towards the outside. The base 12 and the top 13 of each relief 10 are circular. Alternatively, the top and / or the base are non-circular, for example oval. The base 12 of each relief has a diameter D between 1.5 and 6 millimeters, the apex 13 having a diameter of between 0.5 and 4 millimeters. The height of each relief 10 is between 0.8 and 1.2 millimeters, advantageously close to 1 millimeter. In the example, all the reliefs 10 are identical. In another non embodiment. represented, the reliefs are different from one zone 6 to another. In a variant not illustrated, they are also different within the same zone 6.
La périphérie 14 du sommet 13 de chaque relief 10 s'étend vers l'extérieur, au-delà du corps 15 du relief 10. Le diamètre du sommet 13 est donc sensiblement supérieur au diamètre du corps 15, au voisinage de la partie terminale de celui-ci. La périphérie 14 forme ainsi un bord en saillie. Les reliefs 10, relativement souples, ont une hauteur adaptée pour que, lorsque l'utilisateur prend le manche 1 , la peau de ia main ou le gant arrive en contact direct avec la surface supportant les reliefs 10 c'est-à-dire le fond de la zone 6. Les périphéries 14 des sommets 13 agissent alors comme autant d'organes d'accrochage, soit sur la peau de l'utilisateur, soit entre les mailles du gant. La souplesse et la nature du matériau utilisé pour réaliser les reliefs 10 permettent que cet accrochage soit efficace tout en n'étant pas traumatisant et/ou gênant pour l'utilisateur. L'espace entre les rangées 9, 11 et les reliefs 10 favorise l'accrochage et la prise en main sur le manche grâce à une surface de contact importante entre les reliefs 10 et la main de l'utilisateur. Cet accrochage du manche permet de sécuriser la prise et d'améliorer le confort de travail de l'utilisateur. L'espace entre les rangées 9, 11 et les reliefs 10 permet également d'éviter une accumulation de souillure et de faciliter le nettoyage. Un tel manche est d'un entretien aisé et permet une utilisation dans des conditions d'hygiène optimales. L'entretien du manche est également favorisé par l'absence d'angle droit entre la base 12 d'un relief 10 et le fond de Ia zone 6. L'absence. de reliefs, tant sur la face inférieure 7 que supérieure 8 du manche, autorise une tenue du manche de type poignard, c'est-à-dire avec une lame, orientée vers le haut ou le bas, et globalement perpendiculaire à l'avant bras de l'utilisateur.The periphery 14 of the vertex 13 of each relief 10 extends outwardly, beyond the body 15 of the relief 10. The diameter of the vertex 13 is therefore substantially greater than the diameter of the body 15, in the vicinity of the portion terminal of it. The periphery 14 thus forms a projecting edge. The reliefs 10, relatively flexible, have a height adapted so that, when the user takes the handle 1, the skin of the hand or the glove comes into direct contact with the surface supporting the reliefs 10 that is to say the bottom of the zone 6. The peripheries 14 of the peaks 13 then act as many fasteners, either on the skin of the user, or between the mesh of the glove. The flexibility and nature of the material used to make the reliefs 10 allow this attachment is effective while not being traumatic and / or inconvenient for the user. The space between the rows 9, 11 and the reliefs 10 promotes attachment and grip on the handle through a large contact area between the reliefs 10 and the hand of the user. This hooking of the handle makes it possible to secure the grip and to improve the working comfort of the user. The space between the rows 9, 11 and the reliefs 10 also makes it possible to prevent an accumulation of dirt and to facilitate cleaning. Such a handle is easy to maintain and allows use in optimal hygiene conditions. The maintenance of the handle is also favored by the absence of a right angle between the base 12 of a relief 10 and the bottom of zone 6. The absence. reliefs, both on the lower face 7 and upper 8 of the handle, allows holding the dagger-type handle, that is to say with a blade, oriented upwards or downwards, and generally perpendicular to the front arm of the user.
La zone 6 peut être réalisée dans un matériau différent de celui constitutif du manche. En variante, cette zone 6 peut être teintée différemment du reste du manche. Le nombre total des reliefs 10 sur un manche 1 dépend de la géométrie du manche et/ou du type « d'accrochage » souhaité, notamment en fonction du produit travaillé. La densité des reliefs est généralement comprise entre 4 et 11 reliefs par centimètre carré par face 4, 5 du manche 1. Une densité inférieure de reliefs 10 ne permettrait pas d'obtenir un accrochage suffisant. A l'inverse, une densité supérieure conduirait, de facto, à une diminution de la « surface utile » des reliefs. On recréerait ainsi une surface de contact lisse, cette surface étant formée par la somme des aires des sommets 13 des reliefs 10. En d'autres termes, une densité trop élevée de reliefs 10 reviendrait à recréer une répartition uniforme de l'effort exercé sur le manche lors de la prise ce qui annulerait l'effet d'accrochage de chaque relief 10. Une densité trop forte en reliefs serait par ailleurs préjudiciable à l'entretien et au nettoyage du manche. Une densité optimale de reliefs est comprise entre 6 et 8 reliefs au centimètre carré, de manière à assurer une prise en main confortable, efficace et avec un nettoyage aisé du manche, que l'utilisateur porte ou non des gants. Zone 6 may be made of a material different from that constituting the handle. Alternatively, this zone 6 may be tinted differently from the rest of the handle. The total number of reliefs 10 on a handle 1 depends on the geometry of the handle and / or the type of "hooking" desired, especially depending on the product worked. The density of the reliefs is generally between 4 and 11 reliefs per square centimeter per side 4, 5 of the handle 1. A lower density of reliefs 10 would not obtain a sufficient hooking. Conversely, a higher density would lead, de facto, to a decrease in the "useful surface" of the reliefs. A smooth contact surface would thus be recreated, this surface being formed by the sum of the areas of the vertices 13 of the reliefs 10. In other words, a too high density of reliefs 10 would be equivalent to recreating a uniform distribution of the force exerted on the handle when taking what would cancel the hooking effect of each relief 10. A too high density in relief would also be detrimental to the maintenance and cleaning of the handle. An optimal density of reliefs is between 6 and 8 reliefs per square centimeter, so as to ensure a comfortable grip, effective and with easy cleaning of the handle, whether the user wears gloves or not.
