ABSTRACT:
A head for attachment to the body of the electric shaver. The head comprises a guard comb that attaches to the body of the electric shaver, a rotary shaft that extends axially in the guard comb, a plurality of blades that are individual, parallels inclined, and extend in, and to, the guard comb. The plurality of blades have centers through which the rotary shaft extends for rotation therewith, and when rotated by the rotary shaft, the plurality of blades traverse an elliptical path, in a sweeping back and forth motion, by virtue of their incline. The head further includes a sliding trimmer that is slidably mounted in an axial slot in the guard comb, and is operatively connected to a periphery of a blade for axial sweeping back and forth motion as the blade rotate, by virtue of their incline. The sliding trimmer includes a trimmer blade that is slidably mounted on the axial slot in the guard comb and a pair of spaced-apart followers that depend from the trimmer blade, through the axial slot, and straddlably engage the blade for sweeping back and forth movement relative thereto, by virtue of their incline. The guard comb of the head is either semi-cylindrically-shaped with a straight, a convexed, or a concaved axial contour, or has an axial contour comprising a plurality of convexed-semi-circular-shaped portions, with the plurality of blades having shapes and sizes to match the specific contour of the specific guard comb.
