Description

PERFECTIONNEMENT AUX APPAREILS POUR AFFILER LES LAMES D'OUTILS TRANCHANTS  IMPROVING DEVICES TO AFFILIATE TOOLS OF SHARP TOOLS
La présente invention concerne les appareils pour affiler les lames d'outils tranchants ou coupants, en particulier les lames de couteaux.  The present invention relates to apparatus for sharpening the blades of sharp or cutting tools, in particular knife blades.
Les lames d'outils tranchants nécessitent un entretien régulier pour conserver leur pouvoir de coupe.  Sharp cutting blades require regular maintenance to maintain cutting power.
Cet entretien consiste en des opérations régulières d'affûtage au cours desquelles on reforme le taillant au moyen d'une meule ou d'une machine adaptée ; entre deux opérations d'affûtage, l'usure du taillant est retardée par des opérations d'affilage au moyen d'un outil appelé « fusil », au moyen d'un affileur à diabolo, ou encore au moyen d'un module d'affilage à broches croisées (fixes ou articulées).  This maintenance consists of regular grinding operations during which the cutting is reformed by means of a wheel or a suitable machine; between two sharpening operations, the wear of the cutting edge is delayed by sharpening operations by means of a tool called a "rifle", by means of a diabolo sharpener, or by means of a module of sharpening with crossed pins (fixed or articulated).
Le type de fusil d'affilage utilisé est fonction du degré d'usure de la lame. Bien souvent l'opérateur se sert d'un fusil « rugueux » pour dégrossir le travail, avant d'utiliser un fusil de finition « lisse » servant de brunissoir pour le fil de la lame.  The type of sharpening rifle used is a function of the degree of wear of the blade. Often the operator uses a "rough" shotgun to rough out the work, before using a "smooth" finishing gun to burn the blade wire.
Mais la mise en œuvre de ces fusils d'affilage nécessite une technicité importante et un coup de main expérimenté ; en conséquence ils ne peuvent pas être utilisés efficacement par n'importe qui. But the implementation of these sharpening rifles requires significant technical expertise and an experienced hand; as a result they can not be used effectively by anyone.
Les affileurs du type à diabolo ou à broches fixes sont peu efficaces et ne permettent pas d'obtenir une qualité d'affilage intéressante.  The diabolo-type or fixed-pinch-type edgers are inefficient and do not provide an interesting sharpening quality.
Les modules d'affilage du type à broches croisées articulées servent généralement à brunir les lames d'outils et présentent l'intérêt de pouvoir être utilisés de manière satisfaisante même par des personnes ne disposant pas d'une grande expérience ou d'une grande technicité dans le domaine de l'affilage.  The sharpening machines of the articulated cross-pin type are generally used to brown the tool blades and have the advantage of being able to be used satisfactorily even by people who do not have a great deal of experience or a high degree of technicality. in the field of sharpening.
Un appareil de ce genre, décrit dans le document US-A-5 478 272, est constitué d'une base plane dans laquelle est aménagée une fente verticale destinée au passage de la lame à aiguiser, et munie de deux broches d'affilage qui se croisent en regard de ladite fente. Les deux broches d'affilage, réalisées en fil d'acier, ont une forme générale courbe et elles sont articulées au niveau de leur extrémité supérieure sur la base plane, par l'intermédiaire de boutons rotatifs associés à des ressorts de rappel. Ces broches forment entre elles un Vé d'affilage qui est mobile sous la pression de la lame d'outil que l'on désire affiler ; le Vé mobile correspondant permet d'assurer une pression de traitement régulière ou relativement régulière sur la lame d'outil.  An apparatus of this type, described in US-A-5 478 272, consists of a planar base in which is arranged a vertical slot for the passage of the blade to sharpen, and provided with two sharpening pins which intersect opposite the said slot. The two sharpening spindles, made of steel wire, have a generally curved shape and they are articulated at their upper end on the flat base, by means of rotary knobs associated with return springs. These pins form between them a vee sharpening which is movable under the pressure of the tool blade that is desired to sharpen; the corresponding Vee mobile ensures a regular or relatively regular treatment pressure on the tool blade.
Des butoirs inférieurs et supérieurs limitent le pivotement desdites broches entre une position haute et une position basse.  Lower and upper stops limit the pivoting of said pins between a high position and a low position.
Un autre appareil du type à broches croisées articulées, fonctionnant selon le même principe, est décrit dans le document EP-1 260 318.  Another apparatus of the articulated cross-pin type, operating according to the same principle, is described in document EP-1 260 318.
Ici, les broches d'affilage sont portées par une platine métallique dont l'extrémité inférieure se prolonge par une patte monobloc plane située dans le plan de ladite platine, et dont la largeur est décroissante du haut vers le bas. Cette patte sert à la préhension de l'appareil, d'une main, par un opérateur qui souhaite traiter la lame d'un outil tenu par l'autre main ; elle peut aussi servir à la fixation de l'appareil sur un support adapté. La platine de cet appareil (avec sa patte monobloc) est réalisée à partir d'une tôle métallique découpée et pliée. Here, the sharpening pins are carried by a metal plate whose lower end is extended by a flat monobloc tab located in the plane of said plate, and whose width decreases from top to bottom. This tab is used to grip the device, with one hand, by an operator who wishes to treat the blade of a tool held by the other hand; it can also be used to fix the device on a suitable support. The plate of this device (with its monobloc tab) is made from a metal sheet cut and folded.
Mais la tenue de l'appareil par sa patte de préhension, lors du travail sur l'outil, est source de risque de blessure par coupure pour la main de l'opérateur. En outre cette patte ne permet pas une tenue en main optimale de l'appareil.  But the holding of the device by its gripping lug, when working on the tool, is a source of risk of cut-off injury to the hand of the operator. In addition this tab does not allow an optimal grip of the device.
Un appareil du même genre, réalisé en matière plastique moulée, est décrit dans le document DE-10 2007 005 974. Ici encore, la patte de préhension monobloc s'étend dans le même plan que la platine porte-outils ; un volet saillant s'étend vers l'avant, entre la platine porte-outils et la patte de préhension, pour servir d'organe de butée de sécurité.  A similar device, made of molded plastic material, is described in document DE-10 2007 005 974. Here again, the one-piece gripping lug extends in the same plane as the tool-holder plate; a projecting flap extends forwardly between the tool plate and the gripping tab, to act as a safety abutment member.
Ce type d'appareil en matière plastique moulée n'est pas très facile d'entretien et à nettoyer. De plus, les outils en cours de traitement peuvent en couper des petites parties, au risque, dans l'industrie alimentaire, d'en retrouver certaines dans les aliments.  This type of molded plastic device is not very easy to maintain and clean. In addition, the tools being processed can cut small parts, at risk in the food industry, to find some in food.
La présente invention propose un perfectionnement à ce type d'appareil d'affilage, permettant de remédier aux inconvénients précités, facile à fabriquer et à nettoyer, et procurant également une grande sécurité d'utilisation, ainsi qu'une bonne tenue en main.  The present invention provides an improvement to this type of sharpening apparatus, to overcome the aforementioned drawbacks, easy to manufacture and clean, and also providing great safety of use, as well as a good handling.
Pour cela, dans l'appareil d'affilage conforme à la présente invention, l'extrémité inférieure de la platine support de broches se prolonge, du côté de sa face arrière, par un volet intermédiaire, qui lui-même se prolonge par ladite patte de préhension, cette dernière s'étendant dans un plan P' qui est parallèle ou sensiblement parallèle audit plan P de ladite platine, et qui est décalé par rapport à ce plan P, du côté de ladite face arrière de ladite platine. Le volet intermédiaire est délimité par - une bordure avant raccordée à l'extrémité inférieure de ladite platine, - une bordure arrière, parallèle à la bordure avant, raccordée à l'extrémité supérieure de la patte de préhension, et - deux bordures latérales, lesdites bordures avant et arrière définissant la largeur I dudit volet intermédiaire ;  For this, in the sharpening apparatus according to the present invention, the lower end of the pin support plate is extended, on the side of its rear face, by an intermediate flap, which itself is extended by said leg gripper, the latter extending in a plane P 'which is parallel or substantially parallel to said plane P of said plate, and which is offset with respect to this plane P, on the side of said rear face of said plate. The intermediate flap is delimited by - a front edge connected to the lower end of said platen, - a rear border, parallel to the front edge, connected to the upper end of the gripping tab, and - two lateral edges, said front and rear borders defining the width I of said intermediate flap;
et pour optimiser le maintien et la sécurité de la main de l'opérateur, les bordures latérales du volet intermédiaire sont chacune prolongées par une oreille latérale. and to optimize the maintenance and safety of the hand of the operator, the lateral edges of the intermediate flap are each extended by a side ear.
En outre la platine, le volet intermédiaire, la patte de préhension et les oreilles latérales de l'appareil sont réalisés monobloc en tôle métallique découpée et pliée (avantageusement une tôle d'acier inoxydable dont l'épaisseur est comprise entre 2 et 4 mm).  In addition, the plate, the intermediate flap, the gripping tab and the lateral lugs of the apparatus are made in one piece of sheet metal cut and folded (advantageously a stainless steel sheet whose thickness is between 2 and 4 mm). .
Le volet intermédiaire constitue une sorte de butée pour le chant de la main qui porte l'appareil (en particulier pour le dessus du pouce ou de l'index), facilitant ainsi le maintien de l'appareil par cette même main, et limitant sensiblement les risques d'atteinte de cette main par la lame de l'outil en cours de traitement.  The intermediate flap is a kind of stop for the edge of the hand that carries the device (especially for the top of the thumb or forefinger), thus facilitating the holding of the device by the same hand, and substantially limiting the risk of reaching this hand by the blade of the tool being processed.
L'association du volet intermédiaire et des oreilles latérales permet une très bonne ergonomie de l'appareil lorsqu'il est tenu à la main. En effet, la répartition du poids en est améliorée en apportant un appui supplémentaire, en particulier sur le dessus du pouce ou de l'index, et en réduisant l'effort nécessaire de préhension de la poignée. Selon une forme de réalisation préférée, le volet intermédiaire est en forme de volet plan qui s'étend à l'équerre ou sensiblement à l'équerre par rapport au plan P de la platine, et la patte de préhension s'étend à l'équerre ou sensiblement à l'équerre par rapport audit volet intermédiaire. The combination of the intermediate flap and side lugs allows a very good ergonomics of the device when held by hand. Indeed, the distribution of the weight is improved by providing additional support, especially on the top of the thumb or forefinger, and reducing the effort required to grip the handle. According to a preferred embodiment, the intermediate flap is in the form of a plane flap which extends at right angle or substantially at right angles to plane P of the plate, and the gripping tab extends to square or substantially square to said intermediate flap.
Pour assurer un bon maintien et une sécurité optimale, la largeur I du volet intermédiaire est de préférence comprise entre 20 et 40 mm.  To ensure good support and optimum safety, the width I of the intermediate flap is preferably between 20 and 40 mm.
De préférence, les oreilles latérales sont planes et elles s'étendent sur toute ou pratiquement toute la largeur I du volet intermédiaire, dans un plan incliné de quelques degrés, par rapport au plan de ce volet intermédiaire, en direction de la patte de préhension.  Preferably, the lateral lugs are flat and they extend over all or substantially the entire width I of the intermediate flap, in a plane inclined by a few degrees, relative to the plane of this intermediate flap, in the direction of the gripping lug.
L'angle d'inclinaison correspondant de chaque oreille latérale par rapport au plan du volet intermédiaire est avantageusement compris entre 10 et 40°, de préférence entre 20 et 30°. The corresponding angle of inclination of each lateral ear relative to the plane of the intermediate flap is advantageously between 10 and 40 °, preferably between 20 and 30 °.
L'invention sera encore illustrée, sans être aucunement limitée, par la description suivante d'un mode de réalisation particulier, donné uniquement à titre d'exemple et représenté sur les dessins annexés dans lesquels :  The invention will be further illustrated, without being limited in any way, by the following description of a particular embodiment, given solely by way of example and shown in the accompanying drawings in which:

Dans la partie supérieure de cette ouverture 2, la platine 1 comporte des extensions monobloc 3 et 4 constituant des supports, d'une part pour un couple de lames plates 6, 7 destinées à guider la lame de l'outil que l'on désire affiler, et d'autre part pour deux broches d'affilage 8, 9 qui se croisent juste devant lesdites lames de guidage 6, 7.  In the upper part of this opening 2, the plate 1 comprises monobloc extensions 3 and 4 constituting supports, on the one hand for a pair of flat blades 6, 7 intended to guide the blade of the tool that is desired sharpening, and secondly for two sharpening pins 8, 9 which intersect just in front of said guide blades 6, 7.
La platine 1 a une forme générale triangulaire ; elle est plane et s'étend dans un plan P. Cette platine 1 est délimitée par une face avant 10, une face arrière 1 1 , une extrémité supérieure 12, une extrémité inférieure 13 et deux côtés latéraux 14,15.  Platinum 1 has a generally triangular shape; it is flat and extends in a plane P. This plate 1 is delimited by a front face 10, a rear face 1 1, an upper end 12, a lower end 13 and two lateral sides 14,15.
L'ouverture 2 a une forme générale triangulaire qui s'ouvre vers le haut et qui débouche dans l'extrémité supérieure 12.  The opening 2 has a generally triangular shape that opens upwards and opens into the upper end 12.
L'extrémité inférieure 13 de la platine 1 se prolonge vers l'arrière (c'est-à-dire du côté de sa face arrière 1 1 ), à l'équerre ou sensiblement à l'équerre, par un volet intermédiaire monobloc The lower end 13 of the plate 1 extends rearwardly (that is to say on the side of its rear face 1 1), square or substantially square, by a one-piece intermediate flap
16 qui se prolonge lui-même, à l'équerre ou sensiblement à l'équerre, par une patte monobloc16 which extends itself, at the square or substantially square, by a monobloc leg
17 utile pour la préhension de l'appareil, et éventuellement pour sa fixation sur un support adapté. 17 useful for gripping the device, and possibly for its attachment to a suitable support.
Le volet intermédiaire 16 est plan et il présente une forme générale rectangulaire ou sensiblement rectangulaire. Ce volet 16 comporte une bordure avant 18 et une bordure arrière 19, parallèles entre elles, ainsi que deux bordures latérales 20, également parallèles entre elles. La distance séparant ses bordures avant 18 et arrière 19 correspond à sa largeur I. Ce volet 16 s'étend dans un plan perpendiculaire ou sensiblement perpendiculaire par rapport au plan P de la platine 1 ; il se raccorde à l'extrémité inférieure 13 de ladite platine 1 au niveau de sa bordure avant 18. The intermediate flap 16 is flat and has a generally rectangular or substantially rectangular shape. This flap 16 has a front edge 18 and a rear edge 19, parallel to each other, and two side edges 20, also parallel to each other. The distance separating its borders before 18 and rear 19 corresponds to its width I. This flap 16 extends in a plane perpendicular or substantially perpendicular to the plane P of the plate 1; it is connected to the lower end 13 of said plate 1 at its front edge 18.
La patte monobloc 17 présente une forme générale triangulaire avec une largeur décroissante du haut vers le bas ; elle est plane et son extrémité supérieure 21 se raccorde avec la bordure arrière 19 du volet intermédiaire 16.  The one-piece lug 17 has a generally triangular shape with a decreasing width from top to bottom; it is flat and its upper end 21 is connected with the rear edge 19 of the intermediate flap 16.
Cette patte de préhension 17 s'étend dans un plan P' qui est parallèle au plan P de la platine 1 . Ce plan P' est décalé vers l'arrière par rapport au plan P de la platine 1 (c'est-à-dire du côté de la face arrière 1 1 de la platine 1 ), cela d'une distance I correspondant à la largeur du volet intermédiaire 16.  This gripping tab 17 extends in a plane P 'which is parallel to the plane P of the plate 1. This plane P 'is shifted rearward with respect to the plane P of the plate 1 (that is to say on the side of the rear face 1 1 of the plate 1), that of a distance I corresponding to the width of the intermediate flap 16.
D'autre part, on remarque que les bordures latérales 20 du volet intermédiaire 16 se prolongent par des oreilles monobloc 22 dont la largeur correspond sensiblement à celle I dudit volet intermédiaire 16.  On the other hand, it is noted that the lateral edges 20 of the intermediate flap 16 are extended by one-piece lugs 22 whose width corresponds substantially to that of said intermediate flap 16.
Comme on peut le voir en particulier sur les figures 1 à 3, ces oreilles 22 s'étendent dans un plan qui est légèrement décalé angulairement vers le bas (c'est-à-dire en direction de la patte de préhension 17), par rapport au plan du volet intermédiaire 16.  As can be seen in particular in FIGS. 1 to 3, these lugs 22 extend in a plane which is slightly angularly offset downwards (that is to say in the direction of the gripping tab 17), by report to the middle tier plan 16.
L'angle d'inclinaison correspondant a est de préférence compris entre 10 et 40° et encore de préférence entre 20 et 30° ; il est ici de l'ordre de 25°. The angle of inclination corresponding to is preferably between 10 and 40 ° and more preferably between 20 and 30 °; it is here of the order of 25 °.
On comprend que lorsqu'un opérateur tient en main l'appareil d'affilage par la patte 17, le volet intermédiaire 16 sert de garde de protection pour cette main. L'appui de l'index et/ou du pouce contre la surface inférieure de ce volet 16 optimise en plus le maintien de l'appareil Les deux oreilles latérales 22 augmentent la protection obtenue, ainsi que le confort de maintien par une plus grande répartition des surfaces de contact. Leur légère inclinaison vers le bas par rapport au plan du volet 16 permet d'optimiser l'ergonomie de tenue en main.  It will be understood that when an operator holds the sharpening apparatus in his hand by the tab 17, the intermediate flap 16 serves as a protective guard for this hand. The support of the index finger and / or the thumb against the lower surface of this flap 16 further optimizes the maintenance of the apparatus The two lateral lugs 22 increase the protection obtained, as well as the comfort of maintenance by a greater distribution contact surfaces. Their slight inclination downwards relative to the plane of the flap 16 optimizes the ergonomics of handling.
De leur côté, chaque support 3, 4 est en forme générale de L réalisé monobloc avec la platine 1 .  On their side, each support 3, 4 is in the general form of L made in one piece with the plate 1.
En particulier chaque support 3, 4 est ménagé à partir de l'extrémité supérieure de l'ouverture 2, le long de l'une des bordures de cette ouverture 2, et s'étend en porte-à-faux vers l'avant.  In particular each support 3, 4 is formed from the upper end of the opening 2, along one of the borders of this opening 2, and extends cantilevered forward.
Les deux supports 3 et 4 comprennent une embase 23 qui s'étend perpendiculairement au plan P de la platine 1 , prolongée par une aile d'extrémité 24 qui s'étend perpendiculairement à ladite embase 23 et parallèlement au plan P de la platine 1 (dans un plan décalé vers l'avant par rapport au plan P de la platine 1 ).  The two supports 3 and 4 comprise a base 23 which extends perpendicularly to the plane P of the plate 1, extended by an end flange 24 which extends perpendicular to said base 23 and parallel to the plane P of the plate 1 ( in a plane shifted forward with respect to the plane P of the plate 1).
L'embase 23 des supports 3 et 4 comporte un orifice taraudé qui permet la fixation amovible des lames plates 6 et 7 au moyen d'une vis 25. Cet orifice taraudé peut être obtenu au moyen d'un insert taraudé serti sur un orifice ménagé dans l'embase 23.  The base 23 of the supports 3 and 4 comprises a threaded orifice which allows the removable attachment of the flat blades 6 and 7 by means of a screw 25. This threaded orifice can be obtained by means of a threaded insert crimped on a hollow orifice in the base 23.
Les deux lames plates 6 et 7 sont réalisées par exemple en inox; elles sont disposées en vis-à-vis et elles s'étendent perpendiculairement au plan de la platine 1 . Ces lames 6, 7 comportent chacune un retour d'extrémité en L 26 qui permet leur fixation sur les supports 3 et 4 au moyen des vis 25 ; à partir de ce retour en L 26, les deux lames 6 et 7 prennent chacune la forme d'un dièdre pour constituer ensemble un premier Vé évasé 27 dans la partie supérieure de l'ouverture 2, suivi d'un second Vé resserré 28, dans la partie inférieure de ladite ouverture 2 (figure 3). The two flat blades 6 and 7 are made for example of stainless steel; they are arranged vis-a-vis and they extend perpendicular to the plane of the plate 1. These blades 6, 7 each comprise an L-end return 26 which allows their attachment to the supports 3 and 4 by means of the screws 25; from this return in L 26, the two blades 6 and 7 take each the shape of a dihedron together to form a first flared Vee 27 in the upper part of the opening 2, followed by a second constricted Vé 28, in the lower part of said opening 2 (Figure 3).
Les bordures inférieures 29 et 30 des deux lames 6 et 7 viennent en contact l'une avec l'autre pour former un système de guidage auto-serrant.  The lower edges 29 and 30 of the two blades 6 and 7 come into contact with each other to form a self-tightening guide system.
Comme décrit dans le document EP-1 260 318, juste au-dessus de leur bordure inférieure 29 et 30, les deux lames 6 et 7 comportent des découpes internes décalées 31 et 32 qui forment des languettes monobloc pliées en sens inverse l'une de l'autre pour constituer un Vé 33 permettant le redressage du fil de la lame d'outil, dans un alignement parfait.  As described in EP-1 260 318, just above their lower edge 29 and 30, the two blades 6 and 7 have offset internal cutouts 31 and 32 which form one-piece folded tongues in the opposite direction. the other to form a VE 33 for straightening the wire of the tool blade, in perfect alignment.
L'angle que forment entre elles ces deux languettes 31 , 32 est de l'ordre de 40 °. The angle formed between them these two tabs 31, 32 is of the order of 40 °.
Chacune de ces languettes monobloc est associée à une ouverture latérale permettant l'encastrement de la languette homologue.  Each of these one-piece tabs is associated with a lateral opening for embedding the homologous tongue.
Comme décrit dans le document EP-1 260 318, les deux broches d'affilage 8 et 9 sont réalisées en fil métallique, par exemple en fil d'inox. Elles sont constituées d'une tige conformée en U, comportant deux bras parallèles solidaires à l'une de leurs extrémités et dont les extrémités libres comportent des retours monobloc à l'équerre qui viennent s'emmancher dans des orifices appropriés aménagés dans l'aile d'extrémité 24 des supports 3 et 4.  As described in EP-1 260 318, the two sharpening pins 8 and 9 are made of wire, for example stainless steel wire. They consist of a U-shaped rod, comprising two parallel arms secured to one of their ends and whose free ends comprise monobloc returns to the bracket which come to slip into suitable holes arranged in the wing end 24 of the supports 3 and 4.
Cet encastrement des retours de broches dans les orifices associés autorise l'articulation des broches 8 et 9 sur leur support respectif 3, 4, autour d'axes perpendiculaires à la platine support 1 . This embedding of the pin returns in the associated orifices allows the articulation of the pins 8 and 9 on their respective support 3, 4, about axes perpendicular to the support plate 1.
Ces orifices s'étendent perpendiculairement au plan de la platine 1 et ils traversent de part en part l'aile d'extrémité 24 des supports 3 et 4.  These orifices extend perpendicularly to the plane of the plate 1 and they pass right through the end flange 24 of the supports 3 and 4.
A ce niveau on remarque la présence de pièces 24' rapportées par soudage sur les faces externes des ailes 24 pour augmenter leur épaisseur. Ces pièces rapportées 24', dans lesquelles sont ménagés les orifices d'encastrement des broches, servent à maintenir un écart bien défini des deux bras des broches, du fait, ici, de la faible épaisseur de la tôle employée pour former la platine 1 et ses supports monoblocs 3 et 4.  At this level we note the presence of parts 24 'reported by welding on the outer faces of the wings 24 to increase their thickness. These inserts 24 ', in which are formed the recessing holes of the pins, serve to maintain a well-defined separation of the two arms of the pins, because, here, the small thickness of the sheet used to form the plate 1 and its monobloc supports 3 and 4.
Ces pièces 24' évitent aux broches de frotter l'une sur l'autre et elles assurent un pivotement de ces broches sans frottements parasites.  These parts 24 'prevent the pins from rubbing against one another and they provide a pivoting of these pins without parasitic friction.
D'autre part, les orifices ménagés dans ces pièces rapportées 24' et qui se prolongent dans l'aile 24 des supports 3 et 4, assurent un bon guidage des retours de broches et assurent une rotation parfaitement perpendiculaire au plan de la platine support 1 . On the other hand, the orifices formed in these inserts 24 'and which extend in the flange 24 of the supports 3 and 4, ensure good guidance of the pin returns and ensure a rotation perfectly perpendicular to the plane of the support plate 1 .
Les deux orifices correspondants sont désaxés sur chaque aile 24 pour obtenir un système de rappel élastique des broches 8 et 9 par un effet de torsion des deux bras parallèles, comme détaillé dans le document EP-1 260 318. Le positionnement des retours de broches, et celui des deux orifices d'accueil, est adapté pour obtenir les caractéristiques de rappel élastiques désirées. Au repos, les deux bras des broches 8 et 9 sont parallèles, et l'un de ces bras a une longueur un peu plus importante que l'autre pour désaxer les deux retours d'extrémité, afin de permettre leur encastrement dans les orifices associés. The two corresponding orifices are off-center on each wing 24 to obtain an elastic return system of the pins 8 and 9 by a twisting effect of the two parallel arms, as detailed in the document EP-1 260 318. The positioning of the pin returns, and that of the two reception ports, is adapted to obtain the desired elastic return characteristics. At rest, the two arms of the pins 8 and 9 are parallel, and one of these arms has a slightly longer length than the other to offset the two end returns, to allow their embedding in the associated holes .
Ces retours sont orientés en sens inverse l'un de l'autre pour que les deux bras parallèles des broches 8, 9 se positionnent de part et d'autre des ailes d'extrémité 24 des supports 3 et 4, ce positionnement étant possible grâce à l'élasticité de la liaison d'extrémité desdites broches. Les retours correspondants sont simplement emmanchés dans les orifices d'accueil, libres de rotation et amovibles.  These returns are oriented in the opposite direction to each other so that the two parallel arms of the pins 8, 9 are positioned on either side of the end wings 24 of the supports 3 and 4, this positioning being possible thanks to to the elasticity of the end link of said pins. The corresponding returns are simply fitted into the receiving holes, free from rotation and removable.
Les deux broches d'affilage 8 et 9 sont montées imbriquées l'une dans l'autre pour optimiser les opérations d'affilage, et aussi pour limiter l'encombrement de l'appareil.  The two sharpening spindles 8 and 9 are mounted nested one inside the other to optimize the sharpening operations, and also to limit the size of the device.
Sur les figures 1 et 3, on remarque la forme générale courbe des deux broches 8 et 9, qui permet de conserver entre elles un angle de l'ordre de 40°, quelle que soit la profondeur de pénétration de la lame d'outil.  In Figures 1 and 3, note the general curved shape of the two pins 8 and 9, which allows to keep between them an angle of the order of 40 °, regardless of the depth of penetration of the tool blade.
Au repos, les deux broches d'affilage 8 et 9 sont en position haute, leur extrémité étant bloquée par des structures de butées 34 aménagées sur les côtés de la platine 1 . Ces butées 34 peuvent être réalisées monobloc, par pliage des parties latérales de la platine 1 ; elles peuvent aussi être constituées d'éléments indépendants, rapportés et fixés par tout moyen approprié.  At rest, the two sharpening pins 8 and 9 are in the high position, their end being blocked by abutment structures 34 arranged on the sides of the plate 1. These stops 34 can be made in one piece by folding the lateral parts of the plate 1; they may also consist of independent elements, reported and fixed by any appropriate means.
Au repos, on remarque que les deux broches d'affilage 8 et 9 se croisent juste en dessous du niveau de transition entre le Vé évasé 27 et le Vé resserré 28 des lames de guidage 6 et 7.  At rest, it is noted that the two sharpening spindles 8 and 9 intersect just below the level of transition between the flared V 27 and the constricted V 28 of the guide blades 6 and 7.
Dans le mode de réalisation décrit ci-dessus, la platine 1 , le volet intermédiaire 16, les oreilles 22, la patte 17, les supports 3 et 4, ainsi que les butées 34 sont réalisés monobloc à partir d'une tôle métallique découpée et pliée, avantageusement une tôle d'acier inoxydable dont l'épaisseur est comprise entre 2 et 4 mm.  In the embodiment described above, the plate 1, the intermediate flap 16, the lugs 22, the lug 17, the supports 3 and 4, as well as the stops 34 are made in one piece from a cut sheet metal and folded, preferably a stainless steel sheet whose thickness is between 2 and 4 mm.
Dans une variante de réalisation cet ensemble pourrait être obtenu en matière plastique moulée.  In an alternative embodiment this assembly could be obtained from molded plastic.
D'une manière générale, la hauteur de cet appareil peut être de l'ordre de 280 mm, sa largeur de l'ordre de 130 mm, et son épaisseur de l'ordre de 80 mm. La largeur I du volet intermédiaire est avantageusement comprise entre 20 et 40 mm.  In general, the height of this device may be of the order of 280 mm, its width of the order of 130 mm, and its thickness of about 80 mm. The width I of the intermediate flap is advantageously between 20 and 40 mm.
L'appareil d'affilage peut être utilisé tenu en main ou installé dans ou sur un support approprié, fixé sur le poste de travail. L'appareil peut ainsi très facilement être enlevé de son support, en particulier en vue de son nettoyage ou de sa désinfection.  The sharpening apparatus can be used held by hand or installed in or on a suitable stand attached to the workstation. The apparatus can thus very easily be removed from its support, in particular for cleaning or disinfection.
Une découpe interne 35 aménagée dans la patte monobloc 17 permet d'alléger le poids de l'appareil.  An inner cut 35 arranged in the one-piece lug 17 makes it possible to lighten the weight of the apparatus.
Une fois l'appareil tenu en main ou positionné verticalement sur son support, l'opérateur place la lame d'outil qu'il désire affiler entre les deux lames 6, 7 qui forment un guidage auto- serrant. S'il désire utiliser le Vé de redressage 33 formé par les deux languettes monobloc 31 et 32, il exerce une pression verticale sur l'outil, suffisante pour que sa lame atteigne ledit Vé 33 ; l'opérateur peut alors exercer les mouvements de va-et-vient adaptés pour « travailler » le fil de la lame d'outil, d'une manière similaire ou apparentée au travail classique par un fusil « rugueux ». Once the device is held in the hand or positioned vertically on its support, the operator places the tool blade that he wants to sharpen between the two blades 6, 7 which form a self-tightening guide. If he wishes to use the straightening vee 33 formed by the two one-piece tongues 31 and 32, he exerts a vertical pressure on the tool, sufficient for his blade to reach said Vee 33; the operator can then perform the back and forth movements adapted to "work" the wire of the tool blade, in a manner similar or related to conventional work by a "rough" shotgun.
La lame d'outil est alors guidée par le Vé auto-serrant des lames de guidage 6, 7 qui assure un angle de travail parfait.  The tool blade is then guided by the self-clamping vee guide blades 6, 7 which ensures a perfect working angle.
Les deux broches d'affilage 8 et 9 sont ensuite utilisées pour assurer la finition de l'opération d'affilage, c'est-à-dire pour « brunir » ou lisser la lame d'outil, comme on peut le faire de manière classique au moyen d'un fusil « lisse ».  The two sharpening pins 8 and 9 are then used to finish the sharpening operation, ie to "brown" or smooth the tool blade, as can be done classic by means of a "smooth" shotgun.
L'opérateur effectue alors des mouvements de va-et-vient de la lame d'outil sur les deux broches d'affilage 8, 9, en exerçant une pression juste suffisante pour ne pas atteindre le Vé de redressage.  The operator then moves back and forth of the tool blade on the two sharpening spindles 8, 9, exerting a pressure just enough not to reach the straightening Vee.
Les deux broches d'affilage 8 et 9 s'apparentent à des barres de torsion mobiles en forme d'arcs et elles permettent de conserver entre elles, et quelle que soit la profondeur de pénétration de la lame d'outil dans le Vé resserré 28, le bon angle d'attaque permettant d'optimiser le travail sur le fil de la lame.  The two sharpening pins 8 and 9 are similar to mobile torsion bars in the form of arches and they allow to keep between them, and regardless of the depth of penetration of the tool blade in the constricted Vé 28 , the right angle of attack to optimize the work on the wire of the blade.
Le mouvement vers le bas de la lame d'outil est limité par la présence du Vé de redressage 33 et il n'est donc pas nécessaire de prévoir des structures de butées basses pour les deux broches d'affilage 8 et 9. En tout état de cause, les deux broches 8 et 9, imbriquées l'une dans l'autre, ne peuvent pas s'écarter l'une de l'autre en partie inférieure.  The downward movement of the tool blade is limited by the presence of the straightening vee 33 and it is therefore not necessary to provide low abutment structures for the two sharpening pins 8 and 9. In any state Because of this, the two pins 8 and 9, nested one inside the other, can not deviate from each other in the lower part.
Les deux broches d'affilage 8 et 9 comportent intrinsèquement leurs propres moyens de rappel élastiques, ce qui simplifie la structure de l'appareil. En outre, ces deux broches peuvent très facilement être démontées et remontées de leur support, en particulier pour les opérations de maintenance.  The two sharpening pins 8 and 9 intrinsically have their own elastic return means, which simplifies the structure of the device. In addition, these two pins can easily be dismantled and reassembled from their support, especially for maintenance operations.
L'appareil conforme à la présente invention a une structure générale relativement simple et il est très complet puisqu'il propose deux ensembles associés qui permettent de travailler différemment le fil des lames d'outils.  The apparatus according to the present invention has a relatively simple overall structure and is very complete since it proposes two associated assemblies that make it possible to work the wire of the tool blades differently.
D'autre part, la présence du volet intermédiaire 16 et des oreilles monobloc 22 optimisent sa sécurité d'utilisation et sa tenue en main.  On the other hand, the presence of the intermediate flap 16 and one-piece lugs 22 optimize its safety of use and its handling in hand.
