  • 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.

    Abstract: The present invention relates to cutting body hair such as beard stubble. More particularly, the present invention relates to a cutter system for an electric shaver and/or trimmer, with a pair of cooperating cutting elements with at least one row of comb-like cutting teeth. The cutting elements are movably supported relative to each other by a support structure. At least one of the cutting elements, when viewed in cross section, has a C-shape including a pair of dog-eared holding flanges attached to the support structure and a slightly dome shaped or flat center section. The row of comb-like cutting teeth are formed in a transitional section between the dog-eared holding flanges and the center section. The dog-eared holding flange at the transitional section may be provided with a step-like concave depression forming thinned-out tooth tips.
