Field of the Invention
The present ion relates to a hair iron.
Background to the Invention
Many people wish to treat their hair to either create increased volume
or to straighten the hair. For people with vely fine hair that sits flat against
the head, it may be desired to treat the hair to lift the hair away from the head
and create the appearance of a fuller head of hair. Crimping irons can be used
to add small waves to portions of the hair near the scalp to make the hair
stand away from the head and provide increased volume. Crimping irons
generally comprise a pair of heated plates that can be pivoted together around
ns of hair.
Hair straightening irons for straightening wavy or curly hair comprise a
similar construction. That is, a pair of heated plates that can be engaged
around sections of hair to heat the hair and straighten it. In the case of
straightening irons, the heated plates include a flat surface.
The present invention relates to an improved hair iron uction that
may be used for treating the hair, including straightening and volumizing. The
construction of the hair iron makes the process of separating and treating
sections of the hair easier.

Detailed Description of Preferred Embodiments
ing to Figures, there is shown a hair iron 10 comprising generally
a first side member 12 and a second side member 14. Each of the first and
second side members 12 and 14 comprises an elongate member having a
first end 16 and a second end 17.
The first and second side members 12 and 14 are pivotally connected
to each other adjacent the first ends 16. Each of the first and second side
members 12 and 14 includes a first side surface 18. The first side surfaces 18
are generally planar and the first side surface 18 of the first side member 12 is
adjacent the first side surface 18 of the second side member 14.
The pivotal tion between the first and second side members 12
and 14 is provided by a hinge mechanism 20 located adjacent the first ends
16 of the first and second side members 12 and 14. The first and second side
members 12 and 14 are pivotable n a closed position (as shown in
Figure 2), in which the first side surface 18 of the first side member 12 is
adjacent and parallel to the first side surface 18 of the second side member
14, and an open configuration in which the first and second side members 12
and 14 are moved away from each other.
The hinge mechanism 20 is located offset slightly from the first ends 16
of the first and second side s 12. The first and second side members
12 and 14 can therefore be pivoted to the open position by pressing together
the first and second side members 12 and 14 between the hinge mechanism
and the first end 16.
The first end 16 of the first side member 12 is provided with a hook 40
for hanging the heating iron 10. The hook 40 ses a shaft extending
outwardly from the first end 16 of the first side member 12 having a ring on a
distal end thereof.
In the embodiment shown, each of the first and second side members
12 and 14 includes a second side surface 19, being te the first side
surface 18. The second side surfaces 19 are arcuate in transverse cross
section such that each second side surface 19 extends from a first longitudinal
edge 34 of the first side surface 18 to an opposite second longitudinal edge 35
of the first side surface 18.
The first side member 12 is ed with a first heating plate 22
secured to the first side surface 18 thereof. The second side member 14 is
ed with a second heating plate 24 secured to the first side surface 18
thereof. Each of the first and second heating plates 22 and 24 includes a
lower surface that is secured to the first side surface 18 of the corresponding
side member 12 or 14 and an upper surface 21 that is located remote from the
lower surface. The upper surface 21 of the first heating plate 22 is ore
arranged adjacent the upper surface 21 of the second heating plate 24 such
that the upper surfaces 21 engage when the first and second side members
12 and 14 move to the closed uration.
Each of the g plates 22 and 24 extends along a portion of the
length of the associated side member 12 or 14 from a location adjacent the
second end 17 to a location adjacent a midpoint of the side member 12 or 14.
In the embodiment shown, the heating iron 10 is constructed as a
crimping iron in order to add volume to the hair. The upper surfaces 21 of the
first and second heating plates 22 and 24 include udinal corrugations 26
along the length thereof. It will be appreciated though that in the case of the
heating iron 10 being used for htening the hair, the upper surfaces 21 of
the heating plates 22 and 24 would be flat.
The corrugations 26 in the upper surfaces 21 comprise a plurality of
ribs extending parallel to longitudinal axes of the side members 12 and 14.
The corrugations 26 in the first g plate 22 are complementary to the
corrugations 26 of the second heating plate 24. That is, when the first heating
plate 22 engages with the second heating plate 24 (as best seen in Figures 4c
to 4e), the ribs of the first heating plate 22 are received between adjacent
pairs of ribs on the second heating plate 24.
The hair iron 10 is provided also with a heating element on each of the
first and second side members 12 and 14. The heating elements are provided
to apply heat to the heating plates 12 and 14. The g ts comprise
electrical heating elements and a power cord 28 is ed extending from
the first end of the second side member 14 to supply power to the heating
elements.
A heat control may also be provided to control the operation of the
heating elements and thereby the temperature of the heating plates 22 and
24. The heat control in the embodiment shown comprises a dial 30 located on
the first side surface 18 of the second side member 14 between the second
heating plate 24 and the hinge mechanism 20. The dial 30 is located such that
a n of the periphery thereof extends outwardly beyond the first
longitudinal edges 34 of the first and second side members 12 and 14, as best
seen in Figure 3a. The dial 30 can therefore be operated while the first and
second side members 12 and 14 are in the closed position by turning the dial
via the extending portion thereof.
The corrugations 26 are provided on the heating plates 24 such that
the amplitude thereof decreases moving in a direction moving away from a
first longitudinal edge 32 towards a second longitudinal edge 33. That is, the
height of the ribs (and therefore the depth of the grooves between the ribs)
decreases towards the second longitudinal edge 33. The first longitudinal
edge 32 of the heating plates 22 and 24 is the edge ed closest to the
scalp in use.
The ribs in the embodiment shown are generally square in shape. That
is, the corrugations define a generally square waveform sing in
amplitude from the first longitudinal edge 32 towards the second longitudinal
edge 33.
The first and second longitudinal edges of the heating plates 22 and 24
and the first and second longitudinal edges 34 and 35 of the first and second
side members 12 are each curved. The first and second side s 12 and
14 are curved such that the first longitudinal edge 34 is concave in shape to
conform generally to the curvature of the head. The second udinal edge
of the first and second side members 12 and 14 is curved to lly
follow the curve of the first longitudinal edge 34.
In the embodiment shown, the curves in the first and second
longitudinal edges 34 and 35 extend from a location between the first and
second ends 16 and 17 of the first and second arm members 12 and 14 to the
second ends 17 thereof.
From the first ends 16 of the first and second arm members 12 and 14
to a location between the first and second ends 16 and 17 thereof, the first
and second udinal edges 34 and 35 are el to each other. From said
location between the first and second ends 16 and 17, the curve of the second
longitudinal edge 35 is greater than that of the first longitudinal edge 34 such
that the first and second longitudinal edges 34 and 35 approach each other to
form a tapered end portion 21 adjacent the second end 17.
Also, the second side surfaces 19 of the first and second side members
12 and 14 decrease in height above the tive first surfaces 18. That is,
the arcuate shape of the longitudinal cross section of the second side
surfaces 19 decrease in size along a portion adjacent the second end 17 such
that the tapered end portion 21 decreases in cross sectional size towards the
second end. That is, the tapered end portion 21 tapers down to a point.
The first and second side members 12 and 14 are also provided with
an adjustment mechanism to limit the amount by which the first and second
side s 12 and 14 move apart. In the embodiment shown, the
adjustment mechanism comprises a peg 36 provided h an aperture in
the first side member 12 between the hinge mechanism 20 and the first end
An inner end of the peg 36 extends into a space n the first ends
16 of the first and second side members 12 and 14 such that when the side
members 12 and 14 are pivoted towards the open position, the first end 16 of
the second member 14 engages with the inner end of the peg 36. The peg 36
includes a threaded outer surface to engage with an internal thread in the
aperture such that ng the peg 36 causes an inner end to move towards
or away from the second side member 14 to adjust the amount of movement
of the side members 12 and 14 before the engagement with the peg 36.
In use, the hair iron 10 is used to treat sections of the hair for
straightening or crimping. The first and second side members 12 and 14 are
moved to the open configuration and oriented such that the first longitudinal
edge 34 is adjacent and generally parallel to the scalp. The tapered end
portions 21 of the first and second side members 12 and 14 are inserted into
the hair and the hair iron 10 is then moved longitudinally such that a section of
hair is received between the first and second side s 12 and 14. The
d end portions 21 provide easier separation of a section of hair for
treatment.
The hair iron 10 is moved so that a section of hair is received between
the first and second side members 12 and 14 with the hair passing lly
transversely between the first and second side s 12 and 14 with the
hair iron adjacent the scalp. By moving the first and second side members 12
and 14 to the closed position, the portion of the section of hair between the
first and second side members 12 and 14 is clamped between the first and
second g plates 22 and 24.
In the case of heating plates 22 and 24 with corrugations 16, the
corrugations 26 crimp the portion of the hairs and this crimp is set into the hair
by the applied heat. As the corrugations decrease in size towards the second
longitudinal edge 33, the size of the crimp in the hair ses in a direction
away from the scalp. Preferably the first rib on the first heating plate (and
consequently the corresponding groove on the second heating plate) is
located relatively close to the first longitudinal edge 32 such that the first crimp
is placed close to the scalp.
The arrangement of the first and second side members 12 and 14 of
the hair iron 10 and the heating plates 22 and 24 allows ease of use for
separating sections of the hair and crimps the hair only adjacent the scalp, so
the remainder of the hair appears straight. The sing of the crimp size
away from the scalp provides a useful volumizing effect and square wave type
crimp is believed to add a significant amount of volume over a relatively short
section of hair.
In the case of use as a straightening iron, the heating iron 10 can
engage sections of the hair from closely adjacent the scalp and then be
moved outwardly to straighten the hair between the heating plates 22 and 24.
It will be readily apparent to persons skilled in the relevant arts that
various modifications and ements may be made to the foregoing
embodiments, in addition to those already described, without departing from
the basic inventive concepts of the present invention.
