ABSTRACT:
Vibratory shavers are provided having a battery powered DC motor, which when energized rotates a weight eccentrically mounted to a motor shaft. The rotating weight imparts vibratory motion in the shaver housing and thereby a razor cartridge attached to the head of the shaver. The housing is specially designed so that the shaver head will move more front to back than side to side. This can be achieved (a) with the shaver housing having a wider aspect than a front to back aspect; (b) by thickening the side walls of the neck of the shaver relative to the front and back walls of the neck; and (c) by appropriately positioning and designing braces of varied thicknesses. The housing of the shaver may be permanently sealed and provided with a battery that may be recharged via induction. Alternatively, a cap can be provided to provide access to a replaceable battery.
