Patent ID: 7028405

Claim:
A vibratory shaver comprising: a. an outer housing having an elongated body defining front, back and opposite side walls of the body, said side walls of the body connecting side front and back walls of the body, a neck extending essentially axially from the body, and a head attached to the neck at a location remote from the body, said head having a side to side length and a front to back width with said side to side length being elongated relative to said front to back width, the body and neck being formed as an essentially rigid, continuous and non-jointed structure that resists side to side motion along said length of said head to a greater degree than from to back motion. b. a battery positioned in the body; c. a motor capable of being energized by the battery and also being positioned in the body; and d. a weight positioned in the housing and mounted to the motor so as to be rotated thereby to vibrate the housing; wherein the neck is hollow and has side walls and front and back walls, and there is internal bracing extending from one of said neck side walls to the other of said neck side walls, that internal bracing of the neck extending from adjacent an interior surface of said back wall of the neck towards said front wall of the neck; wherein at a given location along the neck, the thickness of the neck side walls exceeds the thickness of the neck front and neck back walls; and that internal bracing of the neck extending from adjacent an interior surface of said back wall of the neck towards said front wall of the neck; wherein at a given location along the neck, the thickness of the neck side walls exceeds the thickness of the neck front and neck back walls; and whereby rotation of the weight causes the head of the shaver to oscillate with a greater front to back amplitude than a side to side amplitude, and side to side flexing of the neck is suppressed, compared to front to back flexing, by the bracing.
