ERGONOMIC HAIR BRUSH
This application relates to a hairbrush which has a shape that when
combined with a selected bristle combination and placement improves the
grooming characteristics of the brush over known brushes of the prior art.
The bristles of the brush described herein are a combination of
double pinned nylon bristles which are the longest bristles in the brush
head and are arranged in rows preferably forming a spiral arrangement on
the brush head. Surrounding the double pinned nylon bristles at each site
in each row is a series of shorter bristles of a different type whose
io function it is to groom the hair in a particular manner for a hair
treatment
operation.
In this instance, the disclosure describes two different types of
shorter bristles which surround the longer doubled pinned nylon bristles.
The shorter bristles of a first type surround the double pinned nylon
bristles in a first row, and the shorter bristles of a second type are made to
surround the double pinned nylon bristles of the next adjacent row.
Each such row always contains double pinned nylon bristles which
have a length such that the outer ends lie in the surface of a right cylinder.
These rows alternate preferably in a spiral fashion over a brush surface
that is described to be concave, so that the entire bush head surface is
CA 02578180 2007-02-12
2 EHO 07191
covered with rows of bristles arranged (in this instance) in spiral fashion.
Each row of bristles is staggered so that the bristles of each row are offset
from each other to ensure excellent engagement with hair being treated.
The surface of the brush head containing the bristle sites may be coated
with a suitable colour changing thermochromic material to indicate to the
brush user the temperature of the surface of the hair brush barrel in which
the bristles are held.
The surface of the hair brush head is therefore concave and is
preferably that of a surface revolution in which the central portion has a
io minimum diameter so as to be a concave surface. The smooth concave
surface is interrupted at the ends to define a sharply rising surface at each
end of the brush head which is enlarged so as to prevent hair tangling
when the operator is performing a hairstyling operation. The end of the
brush remote from the handle is designed to be flat.
SUMMARY OF THE INVENTION
The combination of bristle selection combined with the shape of
the barrel provides a hair brush with superior hair grooming
characteristics. Coupled with this, the barrel of the brush may be coated
with a thermochromic material to indicate the temperature of the brush
barrel. This combination provides the hairstylist with a balanced brush

which is easy to use and has excellent hair grooming qualities which
generally avoids hair tangles to which prior art brushes are subject.
BRIEF DESCRIPTION OF THE DRAWINGS
Figure 1 is a perspective of the brush of the prior art;
Figure 2 is a plan view of the brush of this invention;
Figure 3 is an enlargement of the brush bristle-barrel surface of the
brush of Figure 2.
io DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to Figure 1, a brush 10 of the prior art is shown
having a handle 12 and brush head 14. IIere bristles 16 are shown
protruding through apertures in cylindraceous surface 18 of brush head
14.
is Referring now to Figures 2 and 3, the hair brush 100 of this
invention is illustrated. Here a brush handle 112 is shown being
integrally attached to brush head 114. Brush handle 112 is generally
covered with a soft high friction material. Bristles 116 (hard nylon)
protrude from bristle sites 118 in the surface of brush head 114.
20 Similarly, bristles 116 also protrude from the brush head alternate sites
140.

Note that the bristle sites 118 and 140 are staggered so that there
will be a maximum contact with the strands of hair being first separated
by the long (nylon) bristles 116. Each bristle site always gives rise to at
least one long (nylon) bristle which is surrounded by short bristles of a
specific type. Sites in each row are offset with sites of adjacent rows.
Handle 112 decreases in diameter at 122 and brush head 114
enlarges to form anti-tangle rings 124, 126 at each end of concave surface
of revolution 128. It will be quite evident that the anti-tangle end rings
are formed to be separate from the concave surface 128; there being a
io definite step in the surface topography shown at conical ring surface 130.
Referring specifically to Figure 3, it will be seen that bristle sites
118 and 140 have been shown to illustrate the various positions of
bristles. Each of the bristle sites 118 and 140 always has at least one long
bristle 116 (nylon) projecting therefrom. The bristle sites 118 and 140
is are staggered with respect to each other so as to provide the maximum
contact with the locks of hair being treated on brush 100.
Each of bristle sites such as 120 also supports short bristles (white
boar) 120 as well as long (nylon) bristles 116. Each of the bristle sites
140 supports at least one long (nylon) bristle 116 as well as short black
20 (boar) bristles 142. In this manner, brush 100 may be used to straighten
hair, or it may be used to shine hair.

This brush is ergonomic, that is the handle 112 is shaped to feel
comfortable in the hand of the user and the balance provided by the large
brush head 114 makes the brush feel "good" to the user.
There are many advantages to this brush. First the combination of
s bristles 116, 120 and 142 produces a superior hair grooming performance.
The long nylon bristles 116 provide an extended length of the brush head
bristles so that hair may be conveniently separated and wrapped on brush
head 14 because of early contact with the long stiff nylon bristles 116.
The hair being groomed is then contacted by bristles 120 or 142. These
io bristles serve to either "shine" the hair being contacted (white boar
bristles 120) or the gripping bristles (black boar bristles 142) which are
useful in straightening hair.
The shape of the brush head, the concave surface 128 which may
be coated with a thermochromic colour changing material is a handy
is reference to indicate surface temperature of the brush head. The rows of
bristles may be spiraled (not shotivn) and in any event, the bristles of
different types are staggered to provide maximum contact with the hair
being groomed.
The ends of the brush head are enlarged to prevent tangling of the
2o hair, as prior art brushes are prone to do. With this brush, it is almost
impossible to wrap hair being groomed around the end of the brush.

Because the end of the brush is flat, there is a natural tendency to
place the brush on its head end when not in use. This provides a
convenient storage mode for the brush.
Many modifications and other embodiments of the invention will
come to the mind of one skilled in the art having benefit of the teachings
presented in the foregoing descriptions and the associated drawings.
Therefore, it is to be understood that the invention is not to be limited to
the specific embodiments disclosed, and that the modifications and
einbodiments are intended to be included within the scope of the
io dependent claims.
