Abstract

A hair brush has a semi-circular configuration, and has a head having a support member with a plurality of apertures therein that accommodate a plurality of bristles each having a hollow therein, and has a rear having an elongated hollow therein that complements the semi-circular configuration. When air is applied to the bristles, each bristle communicates with the aperture so that air can flow through the openings of the bristles, the aperture and outward through the hollow in the rear of the hair brush and away from the hair of a user. When air is applied to the hollow in the rear, the air is directed through the apertures and bristles onto the hair of the user.

First claim

What is claimed is:

1. A hair brush comprising:
a head portion having a semi-circular cross-section and a longitudinal axis;
an opening extending from a back to a front of the head portion having a rectangular shape with a length that is substantially the same as a longitudinal length of the head portion;
a convex support member spanning the opening in the head portion, the convex support member having a plurality of apertures; and
a plurality of bristles extending from the convex support member, each of the plurality of bristles forming a flattened triangular shape having a linear base defined at a bottom of the triangular shape and a hole formed through each of the plurality of bristles, the plurality of bristles being arranged in longitudinal rows relative to the longitudinal axis defined by the head portion, the longitudinal rows forming a plurality of primary rows having a portion of the plurality of bristles with each linear base aligned parallel to the longitudinal axis of the head portion and a plurality of secondary rows having another portion of the plurality of bristles with each linear base aligned perpendicular to the longitudinal axis of the head portion, and the plurality of secondary rows each being adjacent to at least one of the plurality of primary rows.

2. The hair brush of claim 1 , wherein the convex support member has the plurality of bristles extending therefrom from a first side and a rear portion opposite the first side that forms a hollow portion with tapered walls.

3. The hair brush of claim 1 , wherein each of the plurality of bristles is aligned with a different one of the plurality of apertures through the convex support member.

4. The hair brush of claim 1 , wherein each of the plurality of bristles has a pair of outer ribs and an inner fin forming the flattened triangular shape having the linear base defined at the bottom of the triangular shape and the hole formed through each of the plurality of bristles.

5. The hair brush of claim 4 , wherein each of the plurality of bristles has a round head where the pair of outer ribs connect.

6. The hair brush of claim 1 , wherein the plurality of secondary rows that are each adjacent to the at least one of the plurality of primary rows are separated from one another by a first constant distance, and each adjacent pairs of bristles of the plurality of bristles are separated from each other along the longitudinal axis by a second constant distance.

7. The hair brush of claim 6 , wherein the first and second constant distances are the same distance.

8. The hair brush of claim 1 , wherein the plurality of bristles are formed in a plurality of columns along a latitudinal axis of the head portion with each adjacent pair of the plurality of columns having a portion of the plurality of bristles positioned perpendicular with respect to one another.

9. The hair brush of claim 8 , wherein the plurality of columns along the latitudinal axis of the head portion have a first column formed by a first portion of the plurality of bristles that are separated from an adjacent second column formed by a second portion of the plurality of bristles by a third constant distance, and each adjacent pairs of bristles in each the first column and the second column are separated from each other along the latitudinal axis by a fourth constant distance.

10. The hair brush of claim 9 , wherein the third and fourth constant distances are the same distance.
