Definitions

  • the present invention relates to an electric apparatus for styling or shaping the hair, more particularly an apparatus for setting the volume of the hair or for detaching the roots of the hair. It is then a question of giving a smooth and curved shape to the hair roots.
  • Most hair setting devices are devices comprising two hot or heated treatment surfaces which come into contact on a lock of hair passing from an open position allowing the insertion of the hair to a closed position. for their contact between the two surfaces.

  • This makes it possible to form different undulations according to the shape of the attached mandrel.
  • ripples it is expected that the mandrel is in contact with the hair over a maximum circumference: it is found that three-quarters of the mandrel are in simultaneous contact with the wick to be waved. This makes it possible to form a greater length of drill bit in several shapes corresponding to several mandrels.
  • This styling device is to ensure good shaping of the hair without, however, making it possible to form a relatively localized volume on the lock of hair treated.
  • a heated hairdressing apparatus for shaping hair comprising a first housing comprising a plate forming at least a first hair treatment surface of concave shape; a second housing comprising a longitudinal mandrel forming a second electrically heated hair treatment surface; the mandrel is in free rotation around its longitudinal axis and is substantially the same radius as the plate; the boxes are pivotally connected by a hinge to define open and closed positions of the device; the concave plate is intended to cover the mandrel in the closed position at a recovery angle ⁇ around 180 °.

  • the flat treatment plates are manually and angularly adjustable relative to the grip handle, the angular mobility being always written in the plane including the flat treatment zone.
  • the treatment surfaces are movable in rotation. This orientation allows the treatment area to be slightly bent when the device is moved along the wick, this making it possible to give a slight undulation to the whole wick.
  • the user must stop using the device, and, when the plates are cooled, turn them manually to return to a strictly straight configuration of the arms.
  • JP4020328 describes a straightener whose branches have a fairly small deflection angle between the handle and the treatment zone, the hinge connection between the two branches being able to be arranged at the end of the branches or else in the middle between the treatment zone and the handle .
  • the user must change the device or break his wrist.

  • This angle formed between the axis of the treatment zone and that of the gripping and actuating means prevents the user from breaking his wrist when he rotates the device for a localized undulation.
  • This angle ⁇ also makes it possible to produce a conventional smoothing.
  • the ergonomics of use are intuitive and all the positions that the device takes in use on the hair allow the hand to remain in a natural position.
  • This angle is defined between two longitudinal axes but the covers of the boxes covering these axes are not necessarily strictly longitudinal with completely straight shapes: the boxes can take a curved shape, for example the shape of a tight curve where the angle ⁇ existing between the support and the treatment surface is not as visible on the outer cover.

  • This configuration as a counter-form makes it possible to statically create a particularly durable undulation at a chosen location of the lock, for example creating detachment at the root of the lock, without damaging the scalp.
  • the two treatment surfaces will create a treatment zone by pinching the hair because they are mounted facing each other in the closed position and their slight or no spacing in the closed position allows the device to be slid along the wick in use.
  • the overlap angle ( ⁇ ) is between 170 ° and 185 °, preferably equal to around 180 °.
  • the value of 180 ° makes it possible to produce a symmetrical device usable by right-handed or left-handed indifferently and in all directions.
  • the value of 180 ° makes it possible to form a natural semicircle with the veil of hair near the scalp.
  • At least one of the two edges longitudinal of the plate has a thickness (e) between 2 and 6mm.
  • This small thickness which follows the mandrel makes it possible to form a pronounced curve as close as possible to the root and with the most natural shape possible.
  • the two longitudinal edges of the plate may each have a thickness (e) of between 2 and 6mm. This allows a right-handed or a left-handed person to work as close as possible to the root.

  • the user begins by turning on the device which then controls the temperature rise of the treatment surface (s).
  • An indicator light can warn that the heating phase has ended.
  • the figure 12 illustrates in detail the steps of the process for forming volume at the root.
  • the user grabs a wick of hair (step a) and introduces the wick, for example at the root, between the treatment surfaces and closes the device (step b) and pinches the wick statically for several seconds (step b) .
  • the housing comprising the concave plate is arranged at the top and the housing comprising the mandrel is arranged at the bottom.
  • step c The edges of the device are applied tangentially to the curve of the scalp. Then the user can rotate (step c) the device around its longitudinal axis (axis parallel or coincident with the axis Lz) about a quarter of a turn down without translating the device (the only movement is substantially pivoting). Then the user slides the device along the wick to its end and upon release of the wick. The result on the hair is illustrated. During tests, the inventors have found that this volume at the root can hold for 1 or 2 days, without having to repeat the process the next day.
