  • Patent number: 11642802
    Abstract: A cutter system for an electric shaver and/or trimmer, having a pair of cooperating cutting elements with two rows of comb-like cutting teeth at opposite edges thereof and at least one field of cutting perforations between the rows of comb-like cutting teeth. The cutting elements are movably supported relative to each other by a support structure with an inner one of the cutting elements being sandwiched between an outer one the cutting element and the support structure. The support structure includes a pair of outer frame portions and a pair of inner frame portions supporting the inner cutting element. The inner frame portions form rigid support ribs extending from a base portion of the support structure at a steeper angle than the outer frame portions and forming rigid support edges supporting the inner cutting element along the outer edge of the field of cutting perforations.

  • Publication number: 20230019742
    Abstract: The present invention relates to cutting body hair such as beard stubbles of multidays' beard. More particularly, the present invention relates to a cutter system for an electric shaver and/or trimmer, comprising an inner cutting element and an outer cutting element forming a pair of cooperating cutting elements with at least one row of comb-like outer cutting teeth extending parallel to a first axis (I), wherein said cutting elements are movably supported relative to each other. Skin irritation may be reduced by the at least one row of comb-like outer cutting teeth having, at a position of 0.2 mm away from the tip, a ratio between tooth width in a direction perpendicular to said first axis (I) and width of an opening slot between two adjacent teeth between 1.0 and 2.0.

  • Publication number: 20210347071
    Abstract: The present invention relates to a cutter system for an electric shaver and trimmer, comprising a pair of cooperating cutting elements with two rows of comb-like cutting teeth at opposite edges thereof and cutting perforations between said rows of comb-like cutting teeth, wherein said cutting elements are movably supported relative to each other by a support structure. The cutting perforations may be arranged in two separated elongated fields of perforations which are separated from each other by an elongated unperforated center section of an outer one of said cutting elements defining a skin contact surface, and which include each at least two rows of perforations extending along the rows of comb-like cutting teeth.
