Definitions

  • the present invention relates to a hair iron.
  • Japanese Unexamined Patent Application Publication No. 2005-198984 discloses a related hair iron including: a pair of grips which are openably provided by turnably joining base ends to each other; and heat generators (holding portions) of a flat shape which are provided to be opposed to each other on tip end sides of the respective grips and are provided with curling portions respectively on back sides thereof.
  • the hair is styled by pulling the hair iron down along the hair with the hair held between the heat generators (the holding portions) opposed to each other, and with unheld portions of the hair pressed against the curling portions.
  • the hair iron cannot curl the hair only by holding the hair between the heat generators (the holding portions) because the heat generators are formed in the flat shape, and thereby may fail to set the hair into a desired style.
  • An object of the present invention is to provide a hair iron which is capable of more certainly setting the hair into a desired style.
  • An aspect of the present invention is a hair iron comprising a first holding portion having a first hair holding surface; and a second holding portion having a second hair holding surface configured to hold hair with the first hair holding surface, wherein the first holding portion includes a protrusion configured to guide hair held between the first hair holding surface and the second holding surface toward the second holding portion.
  • the first holding portion is provided with the protrusion configured to guide the hair toward the second holding portion when holding the hair between the first hair holding surface and the second hair holding surface.
  • the hair can be pushed toward the second holding portion by use of the protrusion.
  • it is possible to style the hair by use of the protrusion, and thereby to style the hair more certainly.
  • it is possible to set the hair more certainly into a desired style.
  • the protrusion may be provided at an end portion of the first holding portion in an extending direction of hair to be held between the first hair holding surface and the second hair holding surface, and extend in a direction intersecting the extending direction of the hair.
  • the protrusion is provided in the end portion of the first holding portion in the extending direction of the hair and in the direction orthogonal to the extending direction of the hair. For this reason, it is possible to push the hair more evenly toward the second holding portion when the hair is held between the first hair holding surface and the second hair holding surface.
  • the protrusion may be provided at each of both end portions of the first holding portion in an extending direction of hair held between the first hair holding surface and the second hair holding surface, and extend in a direction intersecting the extending direction of the hair.
  • the protrusions are provided in both end portions of the first holding portion in the extending direction of the hair in the direction orthogonal to the extending direction of the hair. For this reason, it is possible to style the hair more certainly, and the directions of the hair tips need not be taken into consideration when holding the hair. This improves usability of the hair iron.
  • the protrusion may have a peak in an arc shape.
  • the peak of the protrusion is formed substantially in the shape of an arc, it is possible to reduce a load to be applied to the hair when the hair is held between the protrusion and the second hair holding surface, and thereby to reduce damage on the hair.
  • the first holding portion may include: a holding portion main body; and a hair holding member including the first hair holding surface and being supported by the holding portion main body.
  • the hair holding member may be supported to be reciprocable relative to the holding portion main body in a direction normal to the first hair holding surface.

  • At least one of the first holding portion and the second holding portion may include a heat generator configured to heat hair held between the first hair holding surface and the second hair holding surface.
  • the heat generator configured to apply heat to the hair held between the first hair holding surface and the second hair holding surface, the hair, in which the hydrogen bonds between hair fibers are broken by application of thermal energy, can be pushed toward the second holding portion. Hence, it is possible to style the hair more certainly.
  • the first hair holding surface and the second hair holding surface may have a photocatalytic function.
  • the hair holding surface is provided with the photocatalytic function, it is possible to impart a sterilizing function, a deodorizing function, and the like to the hair holding surface.
  • the first hair holding surface and the second hair holding surface may contain titanium dioxide.
  • a vertical direction is defined based on a hair iron in a state where a first hair holding surface and a second hair holding surface are caused to abut on each other and the second hair holding surface faces upward. Moreover, the description will be made on the assumption that a holding portion-side of the hair iron is defined as the front while a grip portion-side thereof is defined as the back.

  • the upper holding portion 2b and the lower holding portion 3b are respectively provided with a heater 23 and a heater 33 serving as heat generators as shown in Fig. 3 .
  • a curling portion 10e for curling the hair H is provided on an outer surface of the setting member 10.
  • the hair H is set into a curled style or a straight style by: holding the hair H between the upper hair holding surface 22a and the lower hair holding surface 32a formed on the tip end sides of the upper arm portion 2 and the lower arm portion 3; and applying heat generated by the heater 23 and the heater 33 to the hair H through the upper hair holding surface 22a and the lower hair holding surface 32a.
