Abstract
An electrically powered vibrating hair brush including an electric vibratory drive, a handle portion, and a brush head portion driven by the vibratory drive, the brush head portion being non-fixedly mounted onto the handle portion about a longitudinal axis, so as to permit both relative axial movement along the longitudinal axis and relative rotational movement thereabout.
Claims15
An electrically powered vibrating hair brush comprising:
- an electric vibratory drive;
- a handle portion;
- and
- a brush head portion, driven by the vibratory drive,
- the brush head portion comprising a base portion which lies generally in a plane and a multiplicity of bristles which extend outwardly from the base portion, generally perpendicular to the plane, said brush head portion being non-fixedly mounted onto the handle portion about a longitudinal axis, so as to permit both relative axial movement along said longitudinal axis and relative rotational movement thereabout,
- said electric vibratory drive being operative to provide vibration of the brush head portion both in the plane and in a plane perpendicular thereto and perpendicular to the longitudinal axis.

An electrically powered vibrating hair brush comprising:
- an electric vibratory drive;
- a handle portion;
- and
- a brush head portion, driven by the vibratory drive,
- the brush head portion being non-fixedly mounted onto the handle portion about a longitudinal axis, so as to permit both relative axial movement along said longitudinal axis and relative rotational movement thereabout,
- wherein said electric vibratory drive comprises a rotating eccentric drive operative to produce travel of the brush head portion relative to the handle portion along a three-dimensional travel path,
- and wherein said rotating eccentric drive has an axis of rotation which substantially intersects the longitudinal axis.
4 more elements
An electrically powered vibrating hair brush comprising:
- an electric vibratory drive;
- a handle portion;
- and
- a brush head portion, driven by the vibratory drive,
- biasing apparatus, comprising a helical spring, disposed between said brush head portion and said handle portion for absorbing vibration forces produced by the vibratory drive and at least partially preventing the vibration forces from being applied to the handle portion,
- the brush head portion being non-fixedly mounted onto the handle portion about a longitudinal axis, so as to permit both relative axial movement along said longitudinal axis and relative rotational movement thereabout.
