Abstract
A shaving system for use with mechanical hand-held shavers includes a housing in which is disposed a DC motor, an eccentric weight coupled to a shaft of the motor, and a DC power source. The eccentric weight and motor shaft are oriented such that the axis of vibrations produced by the motor are parallel to an axis of the cutting edge of a razor blade attached to a handle in mechanical vibratory communication with the motor. The result is vibratory displacement of the razor blade, typically back-and-forth, over a range approximating the dimension of a human hair. In one embodiment a housing accepts the handle of a generic shaver, and in a second embodiment the housing is bifurcated and the handle of a shaver.
Claims16
A shaving system, comprising:
- a handholdable housing having a centered housing portion, and a distal housing portion, which distal housing portion has a distal tip adapted to receive a razor blade;
- said centered housing portion pivotally joined to said distal housing portion by a pivot axle;
- a DC motor having a rotatable shaft, disposed in said housing;
- an eccentric weight attached to said shaft of said motor;
- and
- a compartment in said housing sized to receive a battery coupleable to energize said DC motor so as to vibrate at least a portion of said distal tip and a razor blade attached thereto.
A method to reduce friction when using a manual shaver of the type having a handle to which a replaceable razor blade is attached, the method including the following steps:
- (a) mounting an eccentric weight on the shaft of a DC motor;
- and
- (b) mechanically coupling vibrations produced by said motor when energized with DC to said handle such that said razor blade is vibrated to produce vibratory displacement approximating a dimension of a human hair.
A shaving system, comprising:
- a handholdable housing having a centered housing portion and a distal housing portion which distal housing portion is adapted to receive a razor blade;
- a DC motor having a rotatable shaft, disposed in said distal housing portion;
- an eccentric weight attached to said shaft of said motor;
- a compartment in said central housing portion sized to receive a battery coupleable to energize said DC motor so as to vibrate at least a portion of said distal tip and a razor blade attached thereto;
- and
- a pin connection between said distal housing portions and said central housing portion.
