Patent ID: 7814601

Claim:
A vibrating hair brush for enhanced detangling of hair, comprising (A) a head portion and (B) a handle portion; the head portion including: an isolator assembly, a motor assembly for operating a vibrating actuator and a plurality of bristles depending from a bristle pad of the head portion, and the handle portion including a handle extending from the head portion in a handle axial direction within a plane generally parallel to the bristle pad, wherein the actuator comprises an offset weight rotating in a plane generally parallel to the bristle pad and is disposed for generating a vibrating movement of the bristles in a curvilinear direction within a plane generally parallel to the bristle pad and wherein the bristle pad is elastomerically supported by the isolator assembly, and wherein the isolator assembly: (a) is supported along a line perpendicular to the handle axial direction, (b) is configured to translate a movement of the offset weight to an elliptical bristle pad vibrating movement, and (c) is configured to inhibit vibrating movement in a direction perpendicular to the handle axial direction, and wherein the isolator assembly has a first stiffness in the handle axial direction and a second stiffness perpendicular to the handle axial direction, the first stiffness being less than the second stiffness.
