Abstract

A hair brush adapted to impart both a straightening effect and a curling effect on a length of hair includes first and second members. The first member includes a first handle and a first brush head having an inner row of centrally disposed primary teeth, an outer row of bristles mounted on each side of the centrally disposed primary teeth, and a thermal conductive element. The thermal conductive element defines an arcuate surface configured for imparting a curl within a lock of hair. The second member includes a second handle, a second brush head having a second head frame defining a longitudinal channel, and an elongate member having a wiper segment disposed on each side of the longitudinal channel, and configured to engage the length of hair to facilitate one of straightening of the length of hair or removing substances from the length of hair.

First claim

What is claimed is:

1. A hair brush, which comprises:
first and second members defining a longitudinal axis and configured for relative movement between open and approximated conditions, the first member including:
a first handle and a first brush head extending from the first handle, the first brush head having:
a first head frame;
an inner row of centrally disposed primary teeth mounted to the first head frame and extending along the longitudinal axis, the centrally disposed primary teeth each defining a first primary dimension along the longitudinal axis and a second primary dimension orthogonal to the longitudinal axis, the second primary dimension being greater than the first primary dimension;
a row of supplemental teeth extending along the longitudinal axis on each side of the centrally disposed primary teeth, the supplemental teeth each defining a first supplemental dimension along the longitudinal axis and a second supplemental dimension orthogonal to the longitudinal axis, the second supplemental dimension being greater than the first supplemental dimension;
an outer row of bristles mounted to the first head frame and extending along the longitudinal axis on each side of the centrally disposed primary teeth; and
a thermal conductive element mounted to an outer surface of the first head frame, the thermal conductive element defining an arcuate surface configured for imparting a curl along a length of hair; and

the second member including a second handle and a second brush head depending from the second handle, the second brush head having:
a second head frame defining an open longitudinal channel extending therethrough configured to receive the centrally disposed primary teeth of the first brush head when the first and second members are in the approximated condition; and
an elongate member disposed on each side of the longitudinal channel, each elongate member having a wiper segment configured to engage the length of hair to impart a straightening effect on the length of hair or to remove substances from the length of hair when the first and second members are in the approximated condition;

wherein the outer rows of bristles are disposed outwardly of respective longitudinal sides of the second brush head when the first and second members are in the approximated condition; and
wherein individual teeth of respective rows of the supplemental teeth are disposed between adjacent individual bristles of respective rows of bristles to define an alternating arrangement of bristles and supplemental teeth along the longitudinal axis.

2. The hair brush according to claim 1 wherein the wiper segment of each elongate member is flexible to conform to the length of hair disposed between the first and second brush heads.

3. The hair brush according to claim 1 wherein the outer rows of bristles are disposed outwardly on respective longitudinal sides of the second brush head when the first and second members are in the approximated condition.

4. The hair brush according to claim 1 wherein the thermal conductive element comprises a metallic material.

5. The hair brush according to claim 1 wherein the first and second members are configured for pivotal movement between the open and approximated conditions.

6. The hair brush according to claim 5 wherein the first and second members are normally biased toward the open condition by a spring member.

7. The hair brush according to claim 6 including a lock mounted relative to the first and second members, the lock movable between a locked position to retain the first and second members in the approximated condition and a release position permitting movement of the first and second members toward the open condition under the influence of the spring member.

8. The hair brush according to claim 1 wherein the first head frame and the thermal conductive member include respective vent openings.

9. The hair brush according to claim 8 wherein the first head frame defines an internal chamber in fluid communication with the vent openings.

10. The hair brush according to claim 1 wherein:
the primary teeth each define a first height;
the supplemental teeth each define a second height; and
the outer bristles each define a third height;
wherein the first height is greater than the second height and the third height.

11. The hair rush according to claim 10 wherein the third height is greater than the second height.

12. The hair brush according to claim 1 wherein individual bristles of the outer rows of bristles are longitudinally offset with respect to individual teeth of the primary teeth.

13. The hair brush according to claim 1 wherein at least portions of the individual teeth of the respective rows of the supplemental teeth are disposed outwardly of respective longitudinal sides of the second brush head when the first and second members are in the approximated condition.
