Title
(EN) CUTTING ASSEMBLY AND TRIMMER COMPRISING THE SAME
(FR) ENSEMBLE DE COUPE ET TONDEUSE LE COMPRENANT
Abstract
(EN)
Provided is a cutting assembly (100) for cutting hairs on skin. The cutting assembly comprises a guard plate (102) for contacting the skin. The guard plate has a first toothed edge (104A) which extends along an axis. The first toothed edge comprises guard teeth (106A). The cutting assembly further comprises a cutter plate (108) which is disposed on the guard plate. The cutter plate is slidable relative to the guard plate in directions parallel with the axis. The cutter plate comprises a second toothed edge (110 A) extending parallel with the axis. The second toothed edge comprises cutting teeth (112A). The cutter plate and the guard plate are aligned such that the hairs are cut by the cutting teeth against the guard teeth when the cutter plate slides. The cutting teeth each include a cutting portion (114A) and a tip (116A). The tip is outwardly enlarged relative to the cutting portion in at least one direction parallel with the axis. The minimum space between adjacent tips is less than the minimum space between adjacent guard teeth. The tip thereby maintains overlap with at least one of the guard teeth during sliding of the cutter plate relative to the guard plate. Further provided is a trimmer including the cutting assembly.
(FR)
L'invention concerne un ensemble de coupe (100) pour couper des poils sur la peau. L'ensemble de coupe comprend une plaque de protection (102) pour entrer en contact avec la peau. La plaque de protection comprend un premier bord denté (104A) qui s'étend le long d'un axe. Le premier bord denté comprend des dents de protection (106A). L'ensemble de coupe comprend en outre une plaque de coupe (108) qui est disposée sur la plaque de protection. La plaque de coupe peut coulisser par rapport à la plaque de protection dans des directions parallèles à l'axe. La plaque de coupe comprend un second bord denté (110A) s'étendant parallèlement à l'axe. Le second bord denté comprend des dents de coupe (112A). La plaque de coupe et la plaque de protection sont alignées de telle sorte que les poils sont coupés par les dents de coupe contre les dents de protection lorsque la plaque de coupe coulisse. Les dents de coupe comprennent chacune une partie de coupe (114A) et une pointe (116A). La pointe est élargie vers l'extérieur par rapport à la partie de coupe dans au moins une direction parallèle à l'axe. L'espace minimal entre les pointes adjacentes est inférieur à l'espace minimal entre les dents de garde adjacentes. La pointe maintient ainsi un chevauchement avec au moins l'une des dents de protection pendant le coulissement de la plaque de coupe par rapport à la plaque de protection. L'invention concerne en outre une tondeuse comprenant l'ensemble de coupe.
