Abstract

The invention relates to a set of guide devices making it possible to sharpen knives, scissors and other cutting tools using dry grinding wheels in a simple and quick fashion and in a way which minimises the risk of damaging the tools. It comprises a holding surface 1 which gives the specific sharpening inclination to the blade of the tool 2 with respect to the grinding wheel 7. A plate 9 which can be adjusted as a function of the various inclinations of the support surface 1 makes it possible to guide the tool blade over its inclined part 10 opposite the inclined part 11 which is in contact with the grinding wheel 7. Amongst the most beneficial applications of the invention, mention may be made of the possibility of offering a sharpening service in multi-service outlets which do not have staff with a specific sharpening training.

Description

La présente invention concerne un ensemble de dispositifs de guidage permettant l'affûtage des couteaux, ciseaux et autres outils de coupe par des meules à sec, d'une façon simple, rapide et qui#miflimise les risques de détérioration des outils. The present invention relates to a set of guide devices allowing the sharpening of knives, scissors and other cutting tools by dry grinders, in a simple, rapid manner and which minimizes the risks of deterioration of the tools.

Dans les appareils d'affûtage connus utilisant des meules à sec 1 'opé- ration est effectuée à main levée et le temps d'affûtage ainsi que la qualité de travail dépendent de l'expérience et de l'habileté de l'opérateur. In known sharpening devices using dry grinding wheels, the operation is carried out by freehand and the sharpening time and the quality of work depend on the experience and skill of the operator.

Sans une expérience spécifique cette opération ne peut être exécutée d'une façon convenable. Même avec l'experience, la rapidité et la qualité du travail dépendent du degré d'habileté de l'opérateur. Les risques de déterioration des- outils sont importants pour un Opérateur sans expérimentation et peuvent subsister également pour un opérateur expérimenté dans le cas d'inadvertances. Without specific experience this operation cannot be carried out in a suitable manner. Even with experience, the speed and quality of work depend on the skill level of the operator. The risks of deterioration of the tools are significant for an operator without experimentation and can also remain for an experienced operator in the event of oversight.

L'ensemble des dispositifs de l'invention permettent d'eviter ces in convenients. Ils permettent en effet à un opérateur sans expérience spécifique d'effectuer cette opération d'une façon rapide, tout en obtenant une qualité d'affûtage convenable et sans risques de détérioration des outils. All the devices of the invention make it possible to avoid these in conveniences. They allow an operator without specific experience to perform this operation quickly, while obtaining a suitable quality of sharpening and without risk of damage to the tools.

La présente invention comprend d'abord un support inclinable selon un angle déterminé qui s'affiche sur une face du support et qui permet de présenter la lame du couteau face à la meule avec une inclinaison adaptée à l'angle d'affûtage déterminé et affiché sur le support. The present invention firstly comprises a support tiltable at a determined angle which is displayed on one face of the support and which makes it possible to present the blade of the knife facing the grinding wheel with an inclination adapted to the determined and displayed sharpening angle. on the support.

La lame de l'outil de coupe est placée dans une position d'affûtage contraire au sens de rotation de la meule. Ceci évite qu'elle ne soit avalée entre la meule et le support par la force de rotation. The blade of the cutting tool is placed in a sharpening position opposite to the direction of rotation of the grinding wheel. This prevents it from being swallowed between the grinding wheel and the support by the rotational force.

Le dessin annexe Figure 1 est une vue en coupe du support pendant l'opération d'affûtage. The accompanying drawing Figure 1 is a sectional view of the support during the sharpening operation.

Tel qu'il est représenté, le support comporte une face de maintien (1) de la lame de l'outil (2). En faisant coulisser le secteur (3) sur l'axe (4) fixe à un corps fixe (5) on obtient des inclinaisons différentes de la surface de maintien (1) par rapport à la tangente (6) de la meule (7). Sur la face (8) de la glissière sont affichées les degrés correspondant à l'angle d'inclinaison (22) entre la surface de maintien (1) et la tangente (6) correspondant à la surface de travail de la meule (7). As shown, the support comprises a holding face (1) of the blade of the tool (2). By sliding the sector (3) on the axis (4) fixed to a fixed body (5) we obtain different inclinations of the holding surface (1) relative to the tangent (6) of the grinding wheel (7) . On the face (8) of the slide, the degrees corresponding to the angle of inclination (22) between the holding surface (1) and the tangent (6) corresponding to the working surface of the grinding wheel (7) are displayed. .

La présente invention comprend ensuite un dispositif réglable qui permet d'obtenir un arrêt contre lequel bute la partie #inclinée de la lame de l'outil sur le coté opposé à celui qui est en contact avec la meule. The present invention then comprises an adjustable device which makes it possible to obtain a stop against which the inclined part of the blade of the tool abuts on the side opposite to that which is in contact with the grinding wheel.

En appuyant la lame de l'outil et en la faisant coulisser contre cet arrêt celle-ci est constamment guidée pendant l'opération d'affûtage.  By pressing the blade of the tool and sliding it against this stop it is constantly guided during the sharpening operation.

Ceci permet d'avoir un affûtage régulier sur toute la longueur, y compris la pointe, de la lame de l'outil. This allows regular sharpening over the entire length, including the tip, of the tool blade.

Le dessin annexe Figure 2 est une vue en coupe du dispositif pendant l'o pération d'affûtage. The accompanying drawing Figure 2 is a sectional view of the device during the sharpening operation.

Tel qu'il est représenté le dispositif comporte une plaquette (9) qui guide la lame de l'outil (2). Sur la partie inclinée (10) la lame est guidée par la plaquette (9) alors qu'elle est en contact avec la meule (7) sur la partie inclinée (11). As shown, the device comprises a plate (9) which guides the blade of the tool (2). On the inclined part (10) the blade is guided by the plate (9) while it is in contact with the grinding wheel (7) on the inclined part (11).

En vissant ou dévissant l'axe taraudé (12) par la poignée (13) et par rapport à la pièce du support taraudée (14) on obtient le déplacement et réglage vertical de la plaquette (9). By screwing or unscrewing the threaded axis (12) by the handle (13) and relative to the part of the threaded support (14), the displacement and vertical adjustment of the plate (9) are obtained.

L'ensemble des pièces (9)-(12)-(13)-(14) est soutenu par l'axe (15) qui coulisse dans le corps fixe (16). En agissant sur la poignée (19) et l'axe taraudé (18) on déplace la plaquette taraudée (17), fixée à l'axe (15). The set of parts (9) - (12) - (13) - (14) is supported by the axis (15) which slides in the fixed body (16). By acting on the handle (19) and the threaded axis (18), the threaded plate (17), fixed to the axis (15), is moved.

Par conséquent, en tournant la poignée (19) on obtient un déplacement horizontal de l'ensemble des pièces (9)-(12)-(13)-(14), ce qui permet un réglage par rapport au diamètre de la meule en fonction de son usure. Consequently, by turning the handle (19), one obtains a horizontal displacement of all the parts (9) - (12) - (13) - (14), which allows an adjustment relative to the diameter of the grinding wheel. depending on its wear.

Le support de la Figure 1 et le dispositif de la Figure 2 agissent simul tanément. Le premier définie l'angle d'affûtage et le deuxième guide la lame pendant l'opération d'affûtage. The support of Figure 1 and the device of Figure 2 act simultaneously. The first defines the sharpening angle and the second guides the blade during the sharpening operation.

Le dessin annexe Figure 3 est une vue en coupe des deux dispositifs des
Figures 1 et 2 illustrant l'action simultanée.The annexed drawing Figure 3 is a sectional view of the two devices of the
Figures 1 and 2 illustrating the simultaneous action.

Tel qu'elle est représentée la plaquette (9) est déplacée verticalement ou horizontalement en fonction de l'angle d'inclinaison de la surface de maintien (1) de façon à guider toujours la lame de l'outil (2) sur la partie:incli née (10) opposée à la partie inclineeqAi est en contact avec la meule (7). As shown, the insert (9) is moved vertically or horizontally depending on the angle of inclination of the holding surface (1) so as to always guide the blade of the tool (2) on the part : inclined (10) opposite the inclined part qAi is in contact with the grinding wheel (7).

La lame de l'outil de coupe (2) est placée dans une position d'affûtage contraire au sens de rotation de la meule. L'angle oc (22) entre la lame de l'outil (2) et la tangente (6) de la meule qui tourne dans le sens (20) est toujours inférieure à 900
Enfin l'invention n'est évidemment pas limitée aux différentes réalisations illustrées et décrites ci-dessus mais au contraire s'étend à toutes les variantes de dispositifs de guidage permettant d'affûter des couteaux, ciseaux et autres outils de coupe par des meules à sec dans lesquels la lame de l'outil, durant l'affûtage, est maintenu inclinée dans le sens contraire à celui de la rotation de la meule, selon un angle déterminé et affiche, de plus, une butée réglable assure le guidage de la lame sur toute la longueur à affûter. The blade of the cutting tool (2) is placed in a sharpening position opposite to the direction of rotation of the grinding wheel. The angle oc (22) between the blade of the tool (2) and the tangent (6) of the grinding wheel which turns in the direction (20) is always less than 900
Finally, the invention is obviously not limited to the various embodiments illustrated and described above, but on the contrary extends to all variants of guide devices making it possible to sharpen knives, scissors and other cutting tools by grinding wheels. dry in which the blade of the tool, during sharpening, is kept inclined in the opposite direction to that of the rotation of the grinding wheel, by a determined angle and displays, moreover, an adjustable stop ensures the guiding of the blade over the entire length to be sharpened.
