ABSTRACT:
An improved hand-held motor-driven oscillating razor for wet shaving provides a substantially vibration-free gripping during the shaving. The razor comprises a grip housing adapted to be gripped by the hand of a user and a shaver head movably supported on top of the grip housing. The shaver head carries a razor blade element and includes a weight which is driven by a motor to impart oscillatory movement to the shaver head. The motor is mounted within the shaver head together with the weight so as to confine an oscillatory system within the shaver head. A damper member is utilized to singly support the shaver head to the grip housing in order to made the shaver head movable with respect to the grip housing such that the grip housing can be isolated substantially from the oscillatory system in the shaver head, permitting the shaver head to oscillate substantially indpendently of the grip housing, thereby minimizing a counter-vibration transmitted back to the grip housing from the shaver head. The damper member is preferably configured to exhibit different elasticity in differing directions in order to minimize the counter vibration which the user feels during the shaving, while assuring effective shaving.
