Abstract

The hair brush (12) includes an elongated member having a handle segment (13) and a bristle substrate segment (14). The bristle substrate defines a cylindrical core having a smoothly curve, concave central region (16) and radially larger end regions (18, 20). A plurality of bristles (25) are attached over the bristle substrate. In a preferred embodiment, the bristles have substantially equal length such that the outer peripheral portions of the plurality of bristles define a smooth curve, concave shape complementary (50) to the concave central region (16) of the bristle substrate. The bristles are further segmented into groups of small bundles and these bundles are disposed over the peripheral surface of the bristle substrate in a series (31). Each series of bristle bundles are axially spaced apart in a common radial plane passing through the axial center line of the brush. A rectangular bristle substrate (70) with a concave shape (74) is also disclosed herein.

INVENTION TITLE: Hair brush The following statement is a full description of this invention, including the best method of performing it known to me/us:- The present invention relates to a hair brush.

Background of the Invention Conventional hair brushes include an elongated member typically including a handle segment and a bristle segment. Commonly, the bristle segment is a solid, cylindrical shape having a constant diameter throughout its axial length.

There is a need in the marketplace for an anatomically correct hair brush.

Objects of the invention It is an object of the p resent invention to provide an anatomically correct hair brush.

It is another object of the present invention to provide a hair brush that has an hourglass shape about its bristle substrate.

It a further object of the present invention to utilize bristles having a substantially equivalent length such that hourglass shape of the substrate is projected radially outward to the outer peripheral edges of the bristles.

•go* It is a further object of the present invention to provide an anatomically correct hair .ooooi brush which requires less force to pass through the user's hair.

o:ooo It is another object of the present invention to provide an anatomically correct hair brush which presents less bristle material in the central mid-region of the brush thereby reducing the force needed to brush one's hair and enhancing the heating and blow drying of one's hair.

Its is a further object of the present invention to provide a brush with a concave substrate, forming a concave shape bristle edges, on a generally rectangular bristle substrate.

It is an additional object of the present invention to provide an anatomically correct hair brush which enables the user to roll-.up more hair on the brush due to hourglass shape of the bristle substrate.

It is an additional object of the present invention to provide an anatomically hair brush wherein the hourglass shape enables a tighter hold on hair wrapped about the hourglass shape bristle system.

It is another object of the present invention to provide an anatomically correct hair brush which, when utilized, creates hair styles with more volume.

Summary of the Invention The hair brush includes an elongated member having a handle segment and a bristle substrate segment. The bristle substrate defines a cylindrical core having a smoothly curve, concave central region and radically larger end regions. A plurality of bristles are attached over the bristle substrate. In a preferred embodiment, the bristles have substantially equal length such that the outer peripheral portions on the plurality of bristles define a smooth curve, concave shape complementary to the concave centrallregion of the bristle substrate. The bristles are further segmented into groups of small bundles and these bundles are disposed over the peripheral surface of the bristle ooooo substrate in a series. Each series of bristle bundles are axially spaced apart in a common radial plane passing through the axial center line of the brush. A rectangular bristle substrate with a concave shape is also disclosed herein.

Brief Description of the Drawings Further objects and advantages of the present invention can be found in the detailed description of the preferred embodiments when taken in conjunction with the accompanying drawings in which: FIG 1. Diagrammatically illustrates a perspective view of the hair brush; FIG.2. diagrammatically illustrates a side view of the hair brush; 3FIG 3. Diagrammatically illustrates the hair brush particularly the hourglass shape or smoothly curved concave central portion of the bristle segment substrate.; FIG 4 diagrammatically illustrates a side view of a rectangular bristle substrate with a concave central region; and FIG 5 illustrates an end view of the brush of FIG 4.

Detailed Description of the Preferred Embodiments The present relates to a hair brush.

FIG 1 diagrammatically shows a perspective view of hair brush 12 FIG 2 i.s diagrammatically illustrates a side view of the hair brush and FIG 3 diagrammatically illustrates a schematic o the hair brush particularly showing the hour glass shape of bristle.

substrate segment 14. The figures are discussed concurrently herein. Similar reference number are utilized in all the figures. Brush 12 includes handle segment 13 and bristle substrate segment 14. As best show in FIG 3, bristle substrate 14 has a generally cylindrical core segment with smoothly curved concave central region 16 and radially larger end regions 18,20. Bristle substrate 14 carries a plurality of bristles 25 on its peripheral surface.

The plurality of bristles 25 are grouped together in small bundles, one of which is identified as bristle bundle 27 in FIG 1. A sub-plurality of bundles are axially aligned in a row such as row 29 shown in FIG 1. Bristle row 29 is linear such that all bundles in the row of bristles are disposed in a common radial plane extending through the axial centerline of the core. See bristle row 31 in FIG 2. Further, the bristle rows are circumferential or angular offset between adjacent radial row of bristles reduces the force necessary to pass the brush through the hair of the user, enables faster drying of the hair with a blow dryer and requires less heat to blow-dry the hair. Further, the hourglass shape of concave central region 16 (FIG 3) enables faster blow drying time, less heat and less effort to brush the user's hair. The brush also gives the hair styles more volume.

The angular offset between radial rows also enhances massaging of the scalp during a brushing session.

Hair brush 12 is anatomically configured such that the hourglass shape of curved concave central region 16 (FIG 3) generally matches curves on the user" head.

Handle segment 14 has a continuously curved convex region 40 and radially smaller end regions 42,44.

The bristles have substantially equivalent lengths 46 such that the outer periphery of a row of bristles defines a smooth curved concave shape about central region 50 that is complementary the hourglass shape 16 of bristle substrate 14.

FIG4. Diagrammatically illustrates hair brush 12 with an elongated, generally rectangular member 44. A cross-sectional aspect of member 44, from the perspective •of section line 80'-80", is generally rectangular in shape. This generally rectangular cross- sectional shape is carried forward to core segment 70 which is part of the bristle substrate segment. FIG 5 shows the end as a rectangular shape.

Brush 12 includes handle segment 78 and a bristle substrate segment extending over region 72. Bristles 25 protrude upward from the smoothly curved concave central region 74 of the elongated, rectangular shape of bristle substrate segment 72. Concave central region 74 and bristles 25 create a concave plurality of bristles at region 76. The angular offset of bristles 25 in linear rows is shown in FIG The brush may be made of wood, plastic, aluminum or other material. Any combination of those elements can be utilized in the brush. The brush can be manufactured with different lengths and in different colors.

The claims appended hereto are meant to cover modifications and changes within the scope and spirit of the present invention.

Throughout this specification and the claims which follow, unless the context requires otherwise, the word "comprise", and variations such as "comprises" and "comprising", will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps.

The reference to any prior art in this specification is not, and should not be taken as, an acknowledgment or any form of suggestion that that prior art forms part of the common general knowledge in Australia.
