Abstract:
A motor-powered depilating device comprising:a hair-plucking assembly, coupled to motor means, and being exposed through an opening in a manually-held housing, said hair-plucking assembly being rotatable about an axis or rotation and including a plurality of disc assemblies, each disc assembly comprising: a pair of complementary discs, each of said discs having at least two radial arms extending outwardly, each one of said complementary discs being mounted, respectively, on each of two axial faces of a hub having a predetermined thickness, said hub having at least two shoulders, each shoulder engaging one of said radial arms so as to impart rotational motion to said pair of discs upon rotation of said hub about the axis of rotation, said hub further including engagement means, for engaging at least one adjoining hub such that rotational motion of one hub imparts rotational motion to said adjoining hub, each of said radial arms terminating in a flattened peripheral portion which, when pressed against a corresponding portion of a complementary disc in a pivoting motion about an edge of said hub, forms a trap for the hair, each trap lying in a predetermined one of a plurality of virtual planes, said virtual planes comprising three substantially parallel planes orthogonal to the axis of rotation, including: a centerplane bisecting said hub thickness, a first offset plane, offset from said centerplane by a first offset dimension, and a second offset plane, offset from said centerplane by a second dimension, said three virtual planes defining a plurality of contiguous depilating coverage zones on the skin surface within said offset dimensions, said at least two shoulders of said hub each having a pair of protrusions which extend axially from each of said shoulders towards adjoining disc assemblies, one on either side thereof, such that, at intervals, during the rotation of said plurality of said disc assemblies, said axial protrusions extend through open spaces between adjacent radial arms of said discs to press a radial arm of an adjoining disc assembly, so as to alternately close and open said hair-traps in said plurality of disc assemblies, wherein at least one of said radially extending arms and its opposing complementary disc radial arm are bent, so that the hair-trap formed thereby lies in a different one of said predetermined virtual planes offset from another hair-trap associated with said disc assembly, thus forming a staggered arrangement of hair-traps, said staggered arrangement of hair-traps thereby plucking skin hair with improved coverage within said depilating coverage zones, and releasing said plucked skin hair.
