DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0032] Referring now to FIGS. 1a and 1b, a hair styling device 10
includes first and second arms 12, 14. Each arm has a handle
portion, 18, 20 which is coupled to a clamping portion 22, 24. The
arms are coupled together via a hinge 16 at one end, adjacent the
handle portions. The hinge 16 may be any type of hinge mechanism
which biases apart the clamping portions 22, 24 of the two arms of
the hair styling device into an open position, as illustrated in
FIGS. 1a, 1b, and 3a. A user can apply a squeezing force to the
handle portions 18, 20 to push the clamping portions 22, 24
together, closing the hair styling device 12. FIG. 3b illustrates
the device 12 in a closed position.
[0033] The clamping portions 22, 24 include inner clamping surfaces
28, 30 which are shaped to receive a curl forming apparatus such as
that described in WO2017/098282.
[0034] FIGS. 3a, 3b, 4a and 4b illustrate various cross-sectional
views through the hair styling device 10. As shown in these
figures, the upper clamping portion 22 includes a concave inner
clamping surface 28, and the lower clamping portion 24 includes a
convex shaped inner clamping surface 30.
[0035] As shown in FIG. 4a, when the clamping portions 22, 24 are
in a closed position the concave inner surface 28 of the upper
clamping portion and the convex inner surface 30 of the lower
clamping portion 24 are spaced apart by a distance labelled X.
[0036] FIGS. 5a, 5b and 5c illustrate an example of a curl forming
apparatus or curler 32 that may be heated with the hair styling
device of the invention. The curler 32 comprises two spaced apart
side portions 40, 42 connected by a centrally located connector
portion 34. The first side portion 40 is substantially flat in
profile and the second side portion 42 is curved in shape. In this
example, the first side portion 40 is provided with barrier members
in the form of five elongate protrusions, or posts 44 which extend
towards the second side portion 42, in substantially the same
direction as the connector portion 34. The second side portion 42
is configured such that it has two fixed states. The first fixed
state is illustrated in FIG. 5a, where the second side portion 42
is convex in shape and curves away from the first side portion 40.
This is the open configuration of the curler 32, and allows for
hair to be wound around the connector portion 34. The second fixed
state is illustrated in FIG. 5c, whereby the second side portion 42
has been folded over so that it is now concave in shape and curves
over the top of the connector portion 34 and the first side portion
40. This is the closed configuration of the curler 32, and allows
hair wrapped around the connector portion 34 to be secured within
the curler 32. The curler 32 is fabricated from a material which is
both resilient and thermally conductive, and the connector portion
24 is preferably hollow, allowing the curler 32 to be
compressed.
[0037] FIG. 4b illustrates the curler 32 clamped between the two
inner clamping surfaces 28, 30. The distance X between the upper
and lower clamping surfaces 28, 30 allows the curler 32 to be
accommodated between the clamping surfaces, but also ensures that
the curler 32 is compressed between the clamping surfaces 28, 30 to
heat the hair located within the curler 32 more efficiently. The
separation distance X is therefore smaller than the length of the
connector portion 34 of the curler 32. The posts 44 which bridge
the gap between the first and second side portions 40, 42 of the
curler 32 are also thermally conductive and in this embodiment,
when the curler is compressed, these posts are in contact with the
heated clamping surfaces, assisting the transfer of heat to the
hair within the curler 32.
[0038] The hair styling device 10 includes a power cord 26 that
extends out from the device 10 adjacent the hinge 16. The upper
clamping portion 22 of the first arm 12 houses a heater element and
the heater element heats the concave inner clamping surface 28
located on the inside of the upper clamping portion 22. The concave
inner clamping surface 28 is fabricated from a thermally conductive
material such as aluminium, steel, titanium, ceramic or other
suitable materials. The upper clamping surface 28 may be ceramic
coated, or tourmaline coated or teflon coated or coated with other
suitable materials. The lower inner clamping surface 30 of the
lower clamping portion 24 may also be heatable by a heater element
which may be located within the lower clamping portion 24. The
lower clamping surface 30 may be fabricated from similar materials
as the upper clamping surface 28. The apparatus may include a
controller which allows a user to control the temperature of one or
both of the clamping surfaces 28, 30, preferably using a switch 36
located on one of the handle portions. Preferably the upper
clamping surface 28 is heatable to a temperature of approximately
220.degree. C. Preferably both the upper and lower clamping
portions include insulation to prevent the external surfaces of the
device 10 from becoming hot to the touch.
[0039] The lower clamping portion 24 may contact a user's head
during use so the lower clamping surface 30 may not be heated to
avoid discomfort. Alternatively, the lower clamping surface 30 may
be heated to a lower temperature than the upper clamping surface
28. The user may be able to select the temperature of the lower
clamping surface 30 from a predetermined choice of three or more
temperatures. For example the temperature of the lower clamping
surface 30 may be altered by sliding a switch 36 or turning a dial
(not shown) to a position corresponding with a desired temperature
setting. Choices of temperature setting may be, for example,
0.degree. C., 70.degree. C., 100.degree. C., 220.degree. C.
[0040] Each of the clamping portions 22, 24 may be provided with a
plurality of venting holes 38.
[0041] In use, several curl formers 32 are applied to the head by
winding strands of hair around the central portion 34 of each curl
former 32. Once the curl former 32 is in position, it is grasped by
the device 10 and clamped between the two clamping portions 22, 24.
The device 10 may include a timer which is initiated on closing the
arms 12, 14 and clamping the clamping portions 22, 24 around the
curl former 32. Preferably an audible alert is emitted after the
curl former 32 has been heated for an optimum amount of time. This
audible alert indicates that the curl former 32 held within the
device 10 has been heated sufficiently and should be released.
Preferably the curl former 32 is heated to a temperature of around
100.degree. C., and the hair within the curl former 32 to a
temperature of around 80.degree. C. Curl formers 32 are only
removed from the hair once they have cooled down and the curl has
set, typically when the temperature of the curl former 32 is
30.degree. C. or less. Several curl formers 32 are typically used
on one head of hair, and each curl former 32 is heated individually
using the hair styling device 10 of the invention.
