PROCEDE DE FABRICATION D'UNE POIGNEE MAGNETIQUE POUR OUTILS A MAIN La présente invention concerne un procédé de fabrication d'une poignée magnétique pour outil à main.  The present invention relates to a method for manufacturing a magnetic handle for a hand tool.

Un outil à main conventionnel comprend généralement une poignée et une tige qui est reliée à la poignée. Il n'existe aucun endroit spécifique pour placer l'outil à main qui pourrait s'éloigner des utilisateurs de telle sorte que les utilisateurs n'arrivent pas à trouver l'outil immédiatement. La figure 1 illustre une poignée 10 d'un outil à main comprenant deux aimants 11 10 reliés à ladite poignée de telle sorte que la poignée 10 puisse être attirée sur une surface métallique par les aimants 11. Les aimants 11 sont facilement neutralisés lorsque les aimants 11 sont touchés par un objet dur. En outre, la poignée 10 ne peut être attirée sur une surface métallique que par la portion sur laquelle se trouvent les aimants 11 de telle sorte que les utilisateurs 15 vérifient la position des aimants 11 avant que l'outil ne soit attiré sur la surface métallique. L'objectif de la présente invention est de proposer un procédé qui mélange des poudres magnétiques dans un matériau de la poignée et qui éjecte le mélange à l'aide d'une machine afin qu'il devienne une poignée. La 20 poignée est ensuite aimantée de manière électrique de telle sorte que la poignée soit magnétique.  A conventional hand tool generally includes a handle and a shank which is connected to the handle. There is no specific place to place the hand tool that could move away from users so that users cannot find the tool immediately. FIG. 1 illustrates a handle 10 of a hand tool comprising two magnets 11 10 connected to said handle so that the handle 10 can be attracted to a metal surface by the magnets 11. The magnets 11 are easily neutralized when the magnets 11 are hit by a hard object. Furthermore, the handle 10 can only be attracted to a metal surface by the portion on which the magnets 11 are located so that the users 15 check the position of the magnets 11 before the tool is attracted to the metal surface. . The object of the present invention is to provide a method which mixes magnetic powders into a material of the handle and which ejects the mixture using a machine so that it becomes a handle. The handle is then electrically magnetized so that the handle is magnetic.

Plus précisément, l'invention a pour objet un procédé de fabrication de poignées magnétiques comprenant les étapes suivantes: - étape 1: le mélange de poudres magnétiques dans un 25 matériau plastique; - étape 2: l'injection du mélange des poudres magnétiques et du matériau plastique dans une poignée à l'aide de l'injection plastique; - étape 3: l'aimantation de la poignée en la reliant à des pôles électriques, et étape 4: la finition finale de la poignée.  More specifically, the subject of the invention is a method of manufacturing magnetic handles comprising the following steps: step 1: mixing magnetic powders in a plastic material; - step 2: injecting the mixture of magnetic powders and plastic material into a handle using plastic injection; - step 3: the magnetization of the handle by connecting it to electrical poles, and step 4: the final finish of the handle.

D'autres caractéristiques, détails et avantages de l'invention ressortiront à la lecture de la description faite en référence aux dessins annexés donnés à titre d'exemple qui représentent respectivement: - La figure 1, une vue en perspective illustrant deux poignées 35 magnétiques conventionnelles d'outils à main; - la figure 2, une vue illustrant les étapes du procédé de la présente invention; et - la figure 3, une vue illustrant le fait que les poignées fabriquées par le procédé de la présente invention sont attirées sur une surface métallique.  Other characteristics, details and advantages of the invention will emerge on reading the description given with reference to the accompanying drawings given by way of example which represent respectively: - Figure 1, a perspective view illustrating two conventional magnetic handles hand tools; - Figure 2, a view illustrating the steps of the method of the present invention; and - Figure 3, a view illustrating that the handles made by the method of the present invention are attracted to a metal surface.

En référence aux figures 2 et 3, le procédé de fabrication de poignées magnétiques comprend l'étape 1 de mélange de poudres magnétiques ou de petites pièces magnétiques dans un matériau plastique, l'étape 2 d'injection du mélange des poudres magnétiques et du matériau 10 plastique dans une poignée 20 à l'aide d'une injection plastique, l'étape 3 d'aimantation de la poignée 20 en la reliant à des pôles électriques, et l'étape 4 de finition finale de la poignée 20.  Referring to Figures 2 and 3, the method of manufacturing magnetic handles comprises step 1 of mixing magnetic powders or small magnetic parts in a plastic material, step 2 of injecting the mixture of magnetic powders and material 10 plastic in a handle 20 using a plastic injection, step 3 of magnetization of the handle 20 by connecting it to electrical poles, and step 4 of final finishing of the handle 20.

La poignée globale 20 est magnétique de telle sorte que les utilisateurs n'ont pas besoin de vérifier l'orientation de la poignée 20 avant le 15 positionnement sur une surface métallique.  The overall handle 20 is magnetic so that users do not need to check the orientation of the handle 20 before positioning it on a metal surface.

L'invention n'est nullement limitée à l'exemple de réalisation donné uniquement à titre d'illustration de l'objet de l'invention.  The invention is in no way limited to the exemplary embodiment given solely by way of illustration of the subject of the invention.
