Abstract

Claims (20)

1 . A hair styling device comprising a first member and a second member, the first and second members being moveable relative to one another between an operative condition and an inoperative condition, the first member having a first heating panel and the second member having a second heating panel, the first and second heating panels being adapted to heat a length of hair as the length of hair moves therebetween and being spaced apart in the operative condition, the length of hair moving along a heating path between the first and second heating panels in use, the first member also having a first pressing panel and the second member also having a second pressing panel, the first and second pressing panels being substantially planar and being closer together than the heating panels in the operative condition, the length of hair moving along a pressing path between the first and second pressing panels in use, the length of the heating path being greater than the length of the pressing path.

2 . A hair styling device according to claim 1 in which the pressing panels are heated in use.

3 . A hair styling device according to claim 2 in which the pressing panels are heated in use to a lower temperature than the heating panels.

4 . A hair styling device according to claim 2 in which each pressing panel is actively heated by a heating element.

5 . A hair styling device according to claim 2 in which the pressing panels are heated by conduction from the heating panels.

6 . A hair styling device according to claim 5 in which the first pressing panel is movable towards and away from the first heating panel and the second pressing panel is movable towards and away from the second heating panel, whereby to adjust the temperature difference between the pressing panels and the heating panels.

7 . A hair styling device according to claim 1 in which the first member and the second member have at least one set of cooperating spacing formations to maintain a predetermined gap between the heating panels in the operative condition.

8 . A hair styling device according to claim 7 in which the first member and the second member are elongate with first and second ends, the first and second members being connected together at a pivoting joint adjacent to the first ends of the members, at least one cooperating spacing formation being adjacent to the second ends of the members.

9 . A hair styling device according to claim 1 in which the first member and the second member have at least one set of cooperating aligning formations to maintain the alignment of the members in the operative condition.

10 . A hair styling device according to claim 1 in which at least one of the first member and the second member is asymmetrical in plan view.

11 . A hair styling device according to claim 1 in which the first pressing panel is movable relative to the first heating panel between an operative position and an inoperative position, and the second pressing panel is movable relative to the second heating panel between an operative position and an inoperative position.

12 . A hair styling device according to claim 1 in which the heating panels are spaced apart by at least 0.5 mm in the operative condition.

13 . A hair styling device according to claim 1 in which the pressing panels are less than 20 mm wide.

14 . A hair styling device according to claim 13 in which the pressing panels have a width of between 10 mm and 15 mm.

15 . A hair styling device according to claim 1 in which the length of the heating path is at least twice the length of the pressing path.

16 . A hair styling device according to claim 15 in which the length of the heating path is at least three times the length of the pressing path.

17 . A method of straightening a length of hair with a hair styling device according to claim 1 by heating the length of hair and pressing the length of hair, in which the heating of the length of hair and the pressing of the length of hair are carried out separately and sequentially.

18 . A method according to claim 17 in which the hair styling device is moved along the length of hair with the first and second members in their operative condition and with the length of hair passing between the heating panels before it passes between the pressing panels.

19 . A hair styling device comprising a first member and a second member, the first and second members being moveable relative to one another between an operative condition and an inoperative condition, the first member having a first heating panel and the second member having a second heating panel, the first and second heating panels being adapted to heat a length of hair as the length of hair moves therebetween and being spaced apart in the operative condition, the length of hair moving along a heating path between the first and second heating panels in use, the first member also having a first pressing panel and the second member also having a second pressing panel, the first and second pressing panels being substantially planar, the length of hair moving along a pressing path between the first and second pressing panels in use, the length of the heating path being greater than the length of the pressing path, in which first and second heating panels are corrugated with the peaks and troughs of the first heating panel facing the troughs and peaks respectively of the second heating panel.

20 . A hair styling device according to claim 19 having a roller at a peak of a corrugation.
