  • Publication number: 20230074295
    Abstract: A cutting mechanism for a hair cutting apparatus, such as a shaving apparatus, includes an outer cutting member having hair-entry openings and an inner cutting member having cutting elements each having a first cutting edge. The inner cutting member is moveable with respect to the outer cutting member so as to perform a cutting operation within a cutting region of the cutting mechanism. Adjacent hair-entry openings are separated by a dividing element having a cutting section that lies within the cutting region and a non-cutting section that is outside the cutting region. The non-cutting section includes an inner wall facing the inner cutting member and a side wall which is substantially perpendicular to the inner wall. A single chamfer is provided between the inner wall of the non-cutting region and the side wall of the non-cutting region.

  • Publication number: 20200061857
    Abstract: There is disclosed a cutting mechanism (4) for a hair cutting apparatus (1), such as a shaving apparatus, comprising an outer cutting member (6) comprising a plurality of hair-entry openings (14) and an inner cutting member (8) comprising a plurality of cutting elements (18) each having a first cutting edge (20). The inner cutting member (8) is moveable with respect to the outer cutting member (6) so as to perform a cutting operation within a cutting region of the cutting mechanism. Adjacent hair-entry openings (14) are separated by a dividing element (16) comprising a cutting section (32) that lies within the cutting region and a non-cutting section (36) that is outside the cutting region. The non-cutting section comprises an inner wall (30) facing the inner cutting member (8) and a side wall (24) which is substantially perpendicular to the inner wall (30). A single chamfer (40) is provided between the inner wall (30) of the non-cutting region and the side wall (24) of the non-cutting region.

  • Patent number: 10456937
    Abstract: A guard element (4) for use in a hair cutting unit as a guard of a movable hair cutting element of the hair cutting unit has a disc-shaped base (10) and an annular wall (20) comprising a main part (21) extending from the periphery of the base (10), and a flange-shaped part (22) comprising an outwardly bent section (24). The annular wall (20) is reinforced on the basis of at least one of a design where a smallest inner periphery of the flange-shaped part (22) has a diameter which is smaller than a diameter of a largest inner periphery of a straight section (23) of the main part (21) connected to the periphery of the base (10), and a design where a free end section (25) of the flange-shaped part (22) is at least partially bent.
