Definitions

  • the present invention relates to a hair straightener with two mutually movable arms and device with at least one curling device.
  • the strand of hair to be treated is placed near the hairline between the arms of the device, taken the strand of hair with the free hand, rotated the hair straightener 180 ° about its longitudinal axis and pulled the hair strand in the rotated state through the arms of the device.
  • the result of hair styling is corkscrew curls.
  • the hair should cool down during the redirection phase so that previously dissolved or weakened hydrogen bonds and ionic interactions stabilize in the new deflected shape.
  • this required cooling takes place through the outer housing of the arms of the device.
  • the diameter of the curls forming is disadvantageously fixed by the diameter of the arms of the device. A flexible and adapted to the user curl diameter can not be achieved by these conventional hair straightener.
  • the object of the present application is therefore to provide an improved hair straightener, which is characterized inter alia by a flexible application, in particular by forming different curl diameters.
  • a hair straightener with a first device arm and a second device arm for treating hair wherein the device arms are connected to one another via a joint and are movable relative to each other.
  • the hair straightener further comprises at least one curling device which can be fastened to the first device arm or attached, wherein the curling device increases the diameter of the first device arm on a side opposite the second device arm side. Between the curling device and the first device arm, a thermal insulation is at least partially arranged.
  • the curling device is advantageously the diameter around which the hair is wound during the curling process, individually adjustable.
  • the diameter around which the hair is wound during the curling process individually adjustable.
  • By means of a single hair straightener curling can be made flexible due to the curling device with advantage, by offering the user the possibility of different degrees defined curls.
  • defined by the Adjustarm a first possible curl diameter and the curling device, a further, in particular larger curl diameter.
  • the thermal insulation between the curling device and the device arm advantageously allows cooling of the hair in its deflection phase.
  • the previously dissolved or weakened hydrogen bonds and ionic interactions in the deflected and thus curled form stabilize upon heating.
  • An improved curl shaping is thus possible with advantage.
  • a "curling device” is to be understood as meaning, in particular, a device which is suitable for shaping curls of, in particular, heated hair.
  • a part-circular body which is preferably directly downstream of a heating region of the hair straightener is suitable for this purpose.
  • the curling device is thermally insulated from the heated area.
  • thermal insulation is meant in the present case, in particular, any insulation which is suitable for preventing or at least weakening heat transfer from the heated region or components of the hair straightener, such as the first device arm, to the curling device.
  • a thermal space or a distance between the curling device and the first device arm, which contains air, is suitable as thermal insulation.
  • the term "attachable” is to be understood in particular as any attachment of the curling device to the first device arm, which can be released again by the user.
  • the curling device is repeatably attachable to the device arm. This means that the user can repeatedly attach the curling device on the first device arm as needed and also replace it again.
  • the term "fastened” is to be understood to mean in particular any attachment of the curling device to the first device arm, which is unsolvable or fixed or fixed.
  • the curling device is therefore not removable from the user from the first device arm here.
  • the curling device can be flexibly attached to the first device arm so far that it is movable at least relative to the first device arm, for example, can be folded away from the first device arm. In this case, however, the curling device is firmly connected at least in one area further to the first device arm.
  • the term "increase the diameter” is to be understood in particular as meaning that the curling device attached to the first device arm increases the outside dimensions of the first device arm.
  • advantageously increases the diameter of the hair straightener, which is provided for curling, thereby increasing the curl diameter formed compared to the straightener without curling device.
  • the thermal insulation is formed from air.
  • a distance between the curling device and the first device arm which contains air.
  • the air causes a deterioration of the thermal conductivity between the device arm and curling device.
  • heat transfer from the first device arm to the curling device is reduced or even prevented, so that the curling device does not unnecessarily heat up during operation of the hair straightener.
  • Mutual and excessive heating of the components of the hair straightener can thus be counteracted.
  • the curling device is formed by way of a half shell.
  • the half-shell is preferably part-circular educated. This means that the curling device at least partially has a round outer shape, which is suitable and intended for hair treatment. The round shape can prevent damage to the hair such as hair abrasion during curling.
  • the first device arm has grooves which are guided in a longitudinal direction of the first device arm and onto which the curling device can be pushed.
  • edges of the grooves are deburred and rounded, so that hair passed by takes no damage during the curling process with the hair straightener without curling device.
  • the curling device Due to the releasable attachment of the curling device to the first device arm, it is possible to cool the curling device separately before the hair-forming process or between the forming of individual hair strands.
  • the curling device placed in a refrigerated compartment, cooled there and then pushed onto the first Adjustarm and used for curling.
  • the hair straightener is accompanied by a plurality of lock devices which can be slid onto the first device arm, so that the user can replace this curling device if necessary, that is to say in particular when the curling device used heats up. This ensures an optimal curl result.
  • the curling device has an electrically conductive material which counteracts a static charge on the hair, which may occur as a result of the rubbing of the hair.
  • this is a light metal such as aluminum or an electrically conductive plastic, which is offset, for example, with silver particles, graphite or carbon nanotubes, or which is itself conductive by a specific arrangement of individual plastic polymers.
  • air-filled cavities are integrated in the curling device, for example in the form of air bubbles.
  • the air causes a deterioration of the thermal conductivity, which counteracts excessive heating of the curling device.
  • the curling device can be configured double-walled, so that a thermal insulation over trapped air is also advantageously formed.
  • the curling device can be folded away from the first device arm and can be fixed in the folded-away state on the first device arm.
  • the fixing is formed via a fixing device attached to the curling device and via a notch formed on the first device arm.
  • the curling device is firmly or fixedly connected to the first device arm on one side.
  • the solid compound is formed by a hinge.
  • the fixing aid is preferably attached to the curling device with a further hinge, whereby the fixing aid can be folded away from the curling device.
  • the fixing aid is designed for example in the form of one or more rods.
  • the curling device and the fixing aid are folded away from the first device arm, the fixing aid is folded away from the curling device and placed and fastened in the notch provided for this purpose.

  • the tying process can be designed to be even more gentle on the hair due to the avoidance of defective friction.
  • the static friction between the hair and the roller surface causes rotation of the roller about its longitudinal axis.
  • the roller is attached at each end to a strut of the curling device.
  • the curling device has a plurality of such rotatable rollers.
  • the second device arm has a second curl device, which enlarges the diameter of the second device arm on a side opposite the first device arm.
  • Embodiments of the second curling device can be designed according to the embodiments of the first curling device.
  • the curling devices are arranged directionally independent on the arms of the device. This means that the arrangement of the curling devices on the first device arm and the second device arm are formed point-symmetrical to each other. The point symmetry is aligned relative to a center of the hair straightener in cross section.
