Abstract

A comb suitable for use as a teasing comb in hair styling is motor-operated so that consistent, high quality results are obtained without tiring the service provider. The motor is light-in-weight and is electrically-powered so that it can be housed in the comb handle. An elongate rocker arm is mounted for pivotal movement so that a leading end of the rocker arm is oscillated when the motor oscillates the trailing end of the rocker arm. The teeth-carrying part of the comb is mounted to the leading end of the rocker arm. At the trailing end of the rocker arm, rotary motion of the motor'"'"'s output shaft is translated into an oscillating, arcuate motion and at the leading end of the rocker arm, the oscillating, arcuate motion is translated into a straight back-and-forth motion having no arcuate component to simulate a manual teasing motion. In one embodiment, the comb is made of a deionizing material that inhibits the buildup of static electrical charges on the comb as the comb strokes the hair. In another embodiment, the comb is made of a dielectric material sandwiched between conductive, oppositely charged plates. In all embodiments, the speed of the motor may be controlled by suitable speed control circuitry.

Claims

1. A hair-treatment apparatus, comprising:

an elongate rocker arm having a leading end and a trailing end;

a pivot means connected to said rocker arm substantially mid-length thereof;

a motor means for oscillating said trailing end of said rocker arm through a predetermined, arcuate path of travel at a predetermined rate of oscillations per unit of time so that said leading end of said rocker arm oscillates in a predetermined, arcuate path of travel at said predetermined rate of oscillation;

a first translation means for translating a rotary output of said motor means into said arcuate path of travel of said trailing end;

an elongate, longitudinally-extending slot formed in said trailing end of said rocker arm;

a transversely disposed pin that extends through said slot;

a radius-defining arm carried by an output shaft of said motor means so that it extends radially relative to an axis of rotation of said output shaft;

said transversely disposed pin being mounted on said radius-defining arm near a free end thereof;

a second translating means for translating the arcuate path of travel of said leading end into a straight back-and-forth motion;

said second translating means including a mounting means adapted to hold a comb so that said comb is displaced in a straight back-and-forth motion so that said comb has utility as a hair-teasing comb;

whereby rotation of said output shaft causes travel of said pin in a circle having a radius determined by a distance between said axis of rotation of said output shaft and said pin, said pin oscillating within said longitudinally-extending slot and oscillating said trailing end of said rocker arm in said arcuate path of travel.

2. The apparatus of claim 1, said second translating means comprising:

an upstanding guide post fixedly secured to a predetermined location in closely spaced apart relation to said leading end of said rocker arm;

said mounting means provided in the form of a slide plate having a bore formed therein for sliding reception of said guide post, said slide plate being fixedly secured to said leading end of said rocker arm; and

connecting means for loosely connecting said slide plate to said leading end of said rocker arm so that said arcuate path of travel of said leading end of said rocker arm is translated into a straight back-and-forth oscillating travel of said slide plate relative to said guide post.

3. The apparatus of claim 2, wherein said connecting means includes a longitudinally-extending slot formed in said leading end of said rocker arm and a fastening means that extends through said slot and engages said slide plate so that a straight back-and-forth component of said arcuate path of travel of said leading end of the rocker arm is transmitted to said slide plate and so that an extending and retracting component of said arcuate path of travel is not transmitted to said slide plate.

4. The apparatus of claim 1, wherein said motor means is an electric motor.

5. The apparatus of claim 4, wherein said electric motor is a nine volt battery-powered motor.

6. The apparatus of claim 4, further comprising a speed control means for controlling the speed of said motor means.

7. The apparatus of claim 6, wherein said speed control means is infinitely adjustable.

8. The apparatus of claim 1, wherein said comb is made of a deionizing material that inhibits build-up of a static electricity charge thereon as said comb is oscillated with respect to said hair.

9. The apparatus of claim 8, wherein said deionizing material is activated charcoal.

10. The apparatus of claim 8, wherein said deionizing material is substantially pure carbon.

11. The apparatus of claim 8, wherein said deionizing material is a resinous material having substantially equal parts of anions and cations.
