ABSTRACT:
A self-powered razor head for shaving hair from a skin surface with at least one reciprocating blade with a roller with an annular skin engaging surface rotatably supported by a support case. In one embodiment, a first razor shuttle has first and second drive arms extending therefrom to travel oppositely in phase against a plurality of ridges and troughs of the roller to induce a reciprocation of the first razor shuttle and a first razor blade that is attached thereto in response to a rotation of the roller. A reciprocation of a second razor shuttle is generated by a pivoting drive lever that has a first end pivotally coupled to the first razor shuttle, a second end pivotally coupled to the second razor shuttle, and a fulcrum point therebetween. Instead of the second drive arm and the ridges and troughs against which it is disposed, the first drive arm may be biased to travel against the plurality of ridges and troughs of the first end of the roller by a resilient biasing member. The ends of the drive lever may be pivotally coupled by a frictional coupling, by restrictive shoulders, or by a unitary formation of that end of the drive lever and a razor shuttle.
