  • Patent number: 6053181
    Abstract: An instrument for styling hair comprises a housing (9), a carrier (10, 11) which is movable supported by the carrier (10, 11), elongate hair guides (12, 13, 14) which project from the carrier (10, 11), a passage (15) for allowing hot air to pass through, and an air guide (17) which is controllable so as to direct the air stream in dependence upon forces exerted on the hair guides (12, 13, 14). The passage (15) and the carrier (10, 11) are adapted to influence the discharge direction in dependence upon the position of the carrier (10, 11) with respect to the housing (9). As the air guide (17) and the carrier (10, 11) are constructed in such a manner that the effective passage area of the passage (15) remains substantially constant when the discharge direction is changed, the air output and the temperature of the emerging air changes hardly when the discharge direction is changed. The hair-style is better under control and less combing and brushing is necessary.

  • Patent number: 5894849
    Abstract: An instrument for styling hair comprises a movable carrier, elongate hair guides which project from the carrier, and a passage for allowing hot air to pass through. The passage and the carrier being adapted to influence the discharge direction in dependence upon the position of the carrier in such a manner that a pivotal movement in a first direction of the carrier with the hair guides which project therefrom results in a change of the discharge direction through the passage in a substantially opposite second direction. During use this prevents hairs just released by the hair guides passing through the hair from being muddled up again. The hair-style is better under control and less combing and brushing is necessary.
