1. A personal grooming device, comprising:
a handle portion (120) having a generally elongate shape; a head portion (110) disposed at an end of the handle portion (120); a razor blade (140) rotatably attached to a face (112) of the head portion (110), and being adapted to reversibly rotate through a one hundred eighty degree range of motion, wherein the razor blade (140) is in an operable orientation at either end of the one hundred eighty degree range of motion; a manually actuatable lever (130) in mechanical communication with the razor blade (140) and adapted to cause the razor blade (140) to reversibly rotate through the one hundred eighty degree range of motion; an enclosure (305A, 305B) defining a hollow space within the head portion (110), wherein the face (112) area of the head portion (110) includes an aperture (309) extending into the hollow space of the head portion (110), the aperture (309) of the face (112) area being adapted to receive a mounting post (333) of the razor blade (140); a planetary gear (330) having a central aperture (335) sharing a common axis with the aperture (309) extending into the hollow space of the head portion (110), the planetary gear (330) being adapted to press fit to the mounting post (333), wherein the planetary gear (330), aperture (309) and mounting post (333) cooperate to define the rotatable attachment between the razor blade (140) and the head portion (110); a sun gear (322) mounted by a pin (321) to an annulus (311) formed upon an interior surface (307) of the enclosure (305B), the sun gear (322) rotatably engaging the planetary gear (330); a linkage having a first end (315), a second end (319), and an off-center pivot point (317) between the first end (315) and the second end (319), wherein the second end (319) of the linkage slidably engages a radial slot (325) in the sun gear (322), and wherein the off-center pivot point (317) engages an annulus (313) formed upon the interior surface (307) of the enclosure (305B); and the lever (130) having tabs (132) at either end, and a recess (134) between the tabs (132), the recess (134) being adapted to engage the first end (315) of the linkage, wherein the tabs (132) of the lever protrude from opposing lever apertures (306) of the enclosure (305A, 305B), wherein the linkage, the sun gear (322) and the planetary gear (330) cooperate to define the mechanical communication between the razor blade (140) and the lever (130). |
