Title
(EN) A SHAVING APPARATUS AS WELL AS A CUTTING UNIT FOR SUCH A SHAVING APPARATUS
(FR) APPAREIL DE RASAGE, ET UNITÉ DE COUPE POUR UN TEL APPAREIL DE RASAGE
Abstract
(EN)
A shaving apparatus (1) provided with at least one cutting unit (3) comprising an external cutting member (4) and an internal cutting member (5) which is drivable relative to the external cutting member in at least one driving direction P. The internal cutting member comprises at least one cutting element (10) comprising a cutting edge (11) being movable along a cutting path (12) whilst being driven in the at least one driving direction. The external cutting member comprises at least one hair-entry aperture (8) which is bounded by at least a first and a second wall portion of the external cutting member, at least the first wall portion (13) comprising a cutting edge A for cooperation with the cutting edge of the internal cutting member. An edge portion of the second wall portion (44, 54) facing a plane comprising the cutting path, in a cross section taken substantially perpendicularly to the plane (22) comprising the cutting path, touches a virtual circle (58) with a radius of at least (30) micrometer at at least two contact points (59, 60) on the virtual circle, and wherein the tangents at two successive contact points where the edge portion touches the virtual circle, enclose an angle of at least 150 degrees.
(FR)
L'invention porte sur un appareil de rasage (1), lequel appareil comporte au moins une unité de coupe (3) comprenant un élément de coupe externe (4) et un élément de coupe interne (5) qui peut être entraîné par rapport à l'élément de coupe externe dans au moins une direction d'entraînement P. L'élément de coupe interne comprend au moins un élément de coupe (10) comprenant un bord de coupe (11) qui est mobile le long d'une trajectoire de coupe (12) tandis qu'il est entraîné dans la ou les directions d'entraînement. L'élément de coupe externe comprend au moins une ouverture d'entrée de poils (8) qui est délimitée par au moins une première et une seconde partie paroi de l'élément de coupe externe, au moins la première partie paroi (13) comprenant un bord de coupe A pour la coopération avec le bord de coupe de l'élément de coupe interne. Une partie de bord de la seconde partie paroi (44, 54) faisant face à un plan comprenant la trajectoire de coupe, dans une coupe transversale prise sensiblement perpendiculairement au plan (22) comprenant la trajectoire de coupe, touche un cercle virtuel (58) avec un rayon d'au moins 30 micromètres en au moins deux points de contact (59, 60) sur le cercle virtuel, et les tangentes au niveau de deux points de contact successifs où la partie de bord touche le cercle virtuel renfermant un angle d'au moins 150 degrés.
