发明名称 Trimmer and double acting blade assemblies for trimmers
摘要 In an embodiment, a pair of blades, one or both of which is adapted to be reciprocated along a longitudinal axis, comprises a first blade and a second blade, each blade having a cutting edge extending along a portion of the blade length. The cutting edge includes a series of teeth. A width of each blade is stepwise reduced along the cutting edge to the distal end so that one or more teeth from the series of teeth has a cutting surface that is receded relative to a tooth from the series of teeth that is closer to the proximal end. The teeth of the series of teeth are uniformly oriented relative to the longitudinal axis.

主权项 1. A pair of blades one or both of which is adapted to be reciprocated along a longitudinal axis, the pair of blades comprising: a first blade having a proximal end,a distal end,a length extending between the proximal end and the distal end, anda cutting edge extending along a portion of the length to the distal end,wherein the cutting edge includes a series of teeth, andwherein a width of the first blade is stepwise reduced along the cutting edge to the distal end so that one or more teeth from the series of teeth has a cutting surface that is receded relative to a tooth from the series of teeth that is closer to the proximal end; and a second blade having a proximal end,a distal end,a length extending between the proximal end and the distal end,a cutting edge extending along a portion of the length to the distal end,wherein the cutting edge includes a series of teeth, andwherein a width of the second blade is stepwise reduced along the cutting edge to the distal end so that one or more teeth from the series of teeth has a cutting surface that is receded relative to a tooth from the series of teeth that is closer to the proximal end.
