## Background
FIELD OF THE INVENTION
The present invention relates broadly to a hairstyling device.
BACKGROUND OF THE INVENTION
Hairstyling often requires drying wet or moist hair. This is traditionally done by directing hot air from a blow dryer onto the hair. This process however, gives the hair a frizzy texture that is not compatible with many desirable hairstyles.
Frizzy hair can be prevented somewhat by the application of a brush to the hair while blow drying hair. Furthermore, the brush and blow dryer combination can achieve a remarkable variety of desirable hairstyles. However, achieving high quality styling with the simultaneous use of a hair brush and blow dryer requires a skilled operator. It can take many years of training before the operator can achieve a satisfactory skill level.
One hairstyle that is particularly difficult to achieve using the brush and blower combination is straight and flat hair. To achieve this style some professional hairstylists use chemical hair straightening techniques, such as “Japanese hair straightening”. It will be understood however, that this is an expensive, permanent process that takes many hours and can result in damage to the hair.
Other stylists use hair irons, also known as straightening irons or hair tongs, which can be used to temporarily straighten hair. Hair irons change the structure of the hair by pressing the hair between two hot iron surfaces. Some hair irons are applied to the hair after blow drying. Others are applied to wet hair.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
One embodiment of a hairstyling device is shown in FIGS. 1 and 2 and generally indicated as 10. The hairstyling device 10 has an elongate arm 12 having a flat and generally rectangular hair receiving surface 14 that extends along part of the arm 12. The hair receiving surface 14 may be made of ceramic or a metal such as aluminium or plastic. Within the arm 12 there is an air passageway 16 that carries air injected into it by a fan 18 driven by an electric motor 20. In this embodiment the fan 18 and motor 20 are mounted in a fan casing 22 rigidly attached to the arm 12, the fan casing 22 also including heating elements 23 to heat the air.
In some other embodiments, however, the fan casing is separate to the arm 12 but connected to the arm 14 by a flexible pipe which is a continuation of the air passageway 16.
The air passageway 16 has an elongate air outlet 24 which is parallel to the arm 12 and extends along the side of the hair receiving surface 14. The air outlet 24 is configured to blow air across the hair receiving surface 14 and thus substantially along the length of the hair placed perpendicular to the arm 12 and on the surface 14. Attached to the hair receiving surface 14 are bristles 26 to form a brush, although in some embodiments the bristles 26 may be placed along an edge of the surface 14. The bristles could be made of nylon; wire, metal, copper, bone, plastic, aluminium, pure bristle or any other type of bristle. In some embodiments not illustrated here, the brush is rotationally mounted on the arm 12 and coupled to an electric motor for driving the brush in a circular motion. The brush is round, but could be another shape such as square. This would help tension the hair.
The hairstyling device 10 is of a modular design and includes a handle or hand grip 28.
This embodiment of a hairstyling device is mains powered, however it may alternatively be powered by batteries.
Another embodiment of hairstyling device is shown in FIG. 3, and is generally indicated as 30. The hairstyling device 30 has a pair of tongs including two elongate arms 32 and 34 that are closable with respect to one another. The arms 32 and 34 are biased or urged away from one another in an open position. Each arm has a generally rectangular hair receiving surface 36 and 38. The surface may be constructed, for example, of ceramic, aluminium or titanium. One or both of the hair receiving surfaces 36 and 38 are heated by a heating element 40 connected directly under the hair receiving surface 36. Within the arm 32 there is an air passageway 42 that carries air injected into it by a fan 44 driven by an electric motor 46. The fan 44 and motor 46 are mounted in a fan casing 48 attached to the arms 32 and 34, the fan casing 48 also including heating elements 50 to heat the air.
The air passageway 42 has an elongate air outlet 52 which is parallel to the arm 32 and extends along the side of the hair receiving surface 36. The air outlet 52 is configured to blow air across the hair receiving surface 36 and thus substantially along the length of hair placed perpendicular to the arm 32 on the surface 36. Attached to the hair receiving surfaces 36 and 38 are bristles 43 to form a brush, although in some embodiments the bristles may be alternatively placed along an edge of the surfaces 36 and 38. In some embodiments, the brush is rotationally mounted on the arm 12 and coupled to an electric motor for driving the brush in a circular motion. This would help to tension the hair.
The hair receiving surfaces 36 and 38 are spring loaded relative to their respective arms 32 and 34 to apply pressure to hair placed between the surfaces 36 and 38 before they are fully closed. There is approximately 2 mm of travel available to each surface.
This embodiment of a hairstyling device is mains powered, however it may alternatively be powered by batteries. The hairstyling device is of a modular design and includes a handle or hand grip 53 to which the arm 12 or tongs are detachably connected. FIG. 4 shows some of the components of the hairstyling device of FIG. 3.
Another embodiment of a hairstyling device, similar to the embodiment of FIG. 3, is shown in FIG. 3a and indicated as 31. Features in FIG. 3a that are common in function to features in FIG. 3 have been identically numbered. The configuration of the elongate air outlet 52 is shown in section A-A of FIG. 3a. The air exiting the elongate air outlet 52 is deflected by a shroud 53 across the hair receiving surfaces 36 and 38 as indicated by the airflow lines. A distinguishing feature of the embodiment of FIG. 3a is that the air heating elements 50 are located within the arms 32 and 34. Another distinguishing feature is that the bristles mounted on a detachable strip run along one side of the hair receiving surfaces 36 and 38. The hairstyling device has a power cord 33 for connecting it to mains power.
FIGS. 5 to 12 show other embodiments of a hairstyling device similar to that shown in FIGS. 3 and 4. The reference numerals used correspond to the parts listing of that drawing.
FIG. 13 shows another embodiment of the hairstyling device generally indicated as 60. In this embodiment the fan casing 62 containing the fan, motor and heating element is separate to the arms 64 and 66 but connected to the arms 64 and 66 by a flexible pipe 68 for transporting the heated air. FIG. 14 shows a more detailed drawing of the arms 64 and 66. FIG. 15 shows a more detailed drawing of the fan casing 62, which is connected to mains power by a power cable 70.
FIG. 16 shows an embodiment of a hairstyling device 80 of the invention in use. Hair 81 is placed between the hair receiving surfaces 82 and 84 and the arms 86 and 88 closed together to grasp the hair. The hairstyling device is then drawn along the tensioned hair 82, in a direction generally away from the scalp 90. The direction of air flow is also generally away from the scalp 90. Importantly, the air flow is directed substantially along the length of the hair away from the scalp 90.
FIGS. 17 and 18 are specification sheets for one embodiment of a hairstyling device according to the invention.
It will be appreciated by persons skilled in the art that numerous variations and/or modifications may be made to the invention as shown in the specific embodiments without departing from the spirit or scope of the invention as broadly described. For example the hair receiving surfaces may not be a straightening plate but a flocked plate, a deep wave plate, or a mirco-crimp plate to curl, crimp, bend, flip, spiral, or straighten the hair. Additionally, there may be means to apply thermal protectors such as lotion to protect the hair during treatment or some other hair product. The brush means may be in the form of relatively rigid comb elements rather than the bristles described. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
