Description détaillée de l'inventionDetailed description of the invention

Pour que l'unité de coupe 2 d'une tondeuse à barbe ou trimmer motorisée soit suffisamment mobile pour adapter automatiquement son angle d'inclinaison de manière optimale à la forme du menton, elle doit avant tout être légère. Ceci ne peut être réalisé qu'en dissociant la fonction moteur de l'unité de coupe et en rapprochant le plus possible l'axe de basculement de l'unité de coupe de la peau, donc de la surface d'appui 11 du peigne 4. Par ailleurs, les contraintes morphologiques du visage font que l'unité de coupe 2 doit être la moins encombrante possible pour pouvoir travailler au niveau de la moustache par exemple.In order for the cutting unit 2 of a motorized beard trimmer or trimmer to be sufficiently mobile to automatically adapt its angle of inclination optimally to the shape of the chin, it must above all be light. This can only be achieved by dissociating the motor function of the cutting unit and bringing as close as possible to the tilting axis of the cutting unit of the skin, therefore of the bearing surface 11 of the comb 4 Moreover, the morphological constraints of the face mean that the cutting unit 2 must be the least bulky possible to be able to work at the mustache for example.

La présente invention divulgue une tondeuse à barbe 1 avec une unité de coupe 2 comportant un mécanisme de coupe 9 et au moins un peigne 4 constituant la surface d'appui 11 de l'unité de coupe 2. L'unité de coupe 2 est articulée autour d'un axe de basculement 8 matérialisé par des points pivots et maintenus par un ou deux bras tendus en avant de la poignée 3 permettant à l'unité de coupe 9 de basculer librement sur un angle (α) suffisant pour s'adapter automatiquement aux courbes du visage.The present invention discloses a beard trimmer 1 with a cutting unit 2 having a cutting mechanism 9 and at least one comb 4 constituting the bearing surface 11 of the cutting unit 2. The cutting unit 2 is hinged around a tilting axis 8 materialized by pivot points and held by one or two arms stretched forward of the handle 3 allowing the cutting unit 9 to freely tilt over an angle (α) sufficient to adapt automatically to the curves of the face.

L'axe de basculement se trouve aligné dans le prolongement de la poignée de sorte que la force d'appui qui est appliquée sur la peau passe à proximité de la ligne de tangence de la surface d'appui 11 du peigne 4.The tilting axis is aligned in the extension of the handle so that the pressing force which is applied to the skin passes close to the line of tangency of the bearing surface 11 of the comb 4.

Afin de faciliter au maximum la rotation de l'unité de coupe 2 autour de l'axe de basculement 8, cet axe doit être le plus proche possible de la peau et donc de la surface d'appui 11 du peigne 4. Par le plus proche possible, nous entendons ce qui est géométriquement faisable en tenant compte de l'encombrement des éléments proches de cet axe. Lorsque les points pivots de l'axe de basculement 8 se trouvent sur le peigne 4, cette distance n'est guère supérieure à 3 ou 4mm. Cette situation est représentée dans les figures 11 et 12. Par contre, lorsque les points pivots de l'axe de basculement 8 se trouvent sur le mécanisme de coupe la distance entre cet axe et la peau varie en fonction de la longueur de coupe choisie par l'utilisateur. Cette situation est représentée dans les figures 6 et 7. Dans ce cas elle ne dépasse néanmoins pas non plus une distance d'environ 8mm lorsque la longueur de coupe est réglée au maximum.In order to facilitate as much as possible the rotation of the cutting unit 2 around the tilting axis 8, this axis must be as close as possible to the skin and therefore to the support surface 11 of the comb 4. By the most close possible, we mean what is geometrically feasible taking into account the size of the elements close to this axis. When the pivot points of the tilt axis 8 are on the comb 4, this distance is hardly greater than 3 or 4mm. This situation is represented in the Figures 11 and 12 . On the other hand, when the pivot points of the tilting axis 8 are on the cutting mechanism, the distance between this axis and the skin varies according to the cutting length chosen by the user. This situation is represented in the Figures 6 and 7 . In this case, however, it does not exceed a distance of approximately 8 mm when the cutting length is set to the maximum.

L'objectif de cette nouvelle tondeuse à barbe est d'offrir à l'utilisateur un dispositif avec une unité de coupe peu encombrante et légère qui permet de tailler les endroits les plus exigus du visage et qui permet en même temps une grande liberté de mouvement, car elle autorise le maintien du bras dans la même position pour plusieurs angles d'attaque différents.The goal of this new beard trimmer is to offer the user a device with a space-saving and lightweight cutting unit that can trim even the smallest areas of the face and at the same time allow great freedom of movement because it allows the arm to be held in the same position for several different angles of attack.

Pour atteindre ce but, l'inventeur a considérablement allégé l'unité de coupe en la séparant conceptuellement de la poignée comportant le bloc moteur et en veillant à une construction où l'axe de basculement est parallèle et le plus proche possible de la peau et donc de la surface d'appui du peigne.To achieve this goal, the inventor has considerably lightened the cutting unit by separating it conceptually from the handle comprising the engine block and ensuring a construction where the tilting axis is parallel and as close as possible to the skin and therefore the support surface of the comb.

La liberté de mouvement de l'unité de coupe 2 autour de l'axe de basculement 8 peut varier dans une plage très large qui peut être comprise entre 10 et 90°. En pratique elle est cependant d'environ 40°, et dans le cas illustré de l'ordre de 25°. Un ressort de rappel 13 représenté à la figure 5 ramène toujours l'unité de coupe dans sa position initiale après application sur la peau. L'angle de basculement est largement tributaire du rapport des distances axe de basculement 8 et surface d'appui 11 du peigne 4 d'une part et la longueur du peigne d'autre part. Dans le contexte de la présente invention, la distance entre l'axe de basculement 8 et la surface d'appui 11 du peigne 4 est la plus faible possible. Le peigne peut se présenter en deux parties, comme sur les figures 4, 6 et 7. Cette configuration en deux parties ne permet cependant pas d'enlever le peigne en le faisant basculer comme montré sur les figures 10a à 10d. Pour pouvoir effectuer cette opération le peigne doit se présenter en une seule pièce comme représenté sur les figures 5 et 10.The freedom of movement of the cutting unit 2 about the tilting axis 8 can vary within a very wide range which can be between 10 and 90 °. In practice, however, it is about 40 °, and in the illustrated case of the order of 25 °. A return spring 13 shown at figure 5 always returns the cutting unit to its initial position after application to the skin. The tilting angle is largely dependent on the ratio of the tilt axis distances 8 and bearing surface 11 of the comb 4 on the one hand and the length of the comb on the other hand. In the context of the present invention, the distance between the tilting axis 8 and the bearing surface 11 of the comb 4 is as small as possible. The comb can be divided into two parts, as on the figures 4 , 6 and 7 . This two-part configuration does not, however, make it possible to remove the comb by tilting it as shown on Figures 10a to 10d . To perform this operation the comb must be in one piece as shown on the figures 5 and 10 .

La distance entre la surface d'appui du peigne 11 et la ligne de coupe 5 peut être adaptée au moyen d'un réglage motorisé se trouvant sur la poignée de la tondeuse à barbe selon l'invention. Cette distance déterminera la longueur de coupe désirée de la barbe. Le réglage peut se faire aisément et avec précision si l'utilisateur décide de tailler sa barbe à des longueurs différentes selon les endroits. Le réglage peut se faire en adaptant la position du peigne 4 et donc de la surface d'appui 11 ce qui nécessite dans ce cas précis une mobilité du peigne 4 (Figures 11 et 12). Elle peut cependant également se faire en maintenant le peigne 4 fixe et en adaptant la position de la ligne de coupe 5 ce qui nécessite alors une mobilité du mécanisme de coupe 9 (Figures 6 et 7).The distance between the support surface of the comb 11 and the cutting line 5 can be adapted by means of a motorized adjustment on the handle of the beard trimmer according to the invention. This distance will determine the desired cutting length of the beard. The adjustment can be done easily and accurately if the user decides to trim his beard to different lengths depending on the location. The adjustment can be done by adapting the position of the comb 4 and therefore of the bearing surface 11 which requires in this case a mobility of the comb 4 ( Figures 11 and 12 ). However, it can also be done by maintaining the fixed comb 4 and adapting the position of the cutting line 5, which then requires a mobility of the cutting mechanism 9 ( Figures 6 and 7 ).

La poignée peut également comporter une indication de la longueur de coupe désirée ; celle-ci varie généralement de 0,3 à 6mm, de préférence de 0,5 à 5mm.The handle may also include an indication of the desired cutting length; this generally varies from 0.3 to 6 mm, preferably from 0.5 to 5 mm.
