Definitions

  • the present invention relates to a housing of a hair styling apparatus for housing component parts of the hair styling apparatus and in particular to a housing to which arms of a hair styling apparatus may be pivotally coupled.
  • Hair styling apparatuses such as hair straighteners or hair curlers are well known.
  • Typical hair straighteners that have become widely used in recent decades involve two arms pivoted together at one end.
  • a spring biases the arms apart and each arm houses a plate that is electrically heated, with the plates arranged to oppose one another.
  • the user operates the straightener by placing it such that the hair is located between the two opposing plates and then forces the arms together against the biasing force of the spring to clamp the hair between the plates. After holding for a desired amount of time, the user releases the force on the straightener and the spring urges the arms apart, thereby releasing the now-straightened hair.
  • Hair curlers typically have a barrel-shaped styling part around which the user’s hair can be wrapped.
  • the barrel-shaped styling part is electrically heated.
  • the user coils their hair around the styling part and holds for a short time, and then unravels their now-curled hair from the styling part.
  • Some hair styling apparatuses involves two arms which may be used in a straightening function as described above, but when the arms come together, they form a barrel-shaped styling part that can also be used for curling hair.
  • a power cable is fitted to an end of one of the arms of the hair styling apparatus, and the interior wiring extends along each arm to the heatable plates located at the styling part.
  • the arms are typically pivoted together by a pivot pin, with the pivot point being located forward of where the power cable connects to one of the arms.
  • the arms are not symmetrical and the distribution of weight on the straightener is uneven.
  • the arms When the arms are opened, the arms at one side of the pivot point move apart, but at the other side of the pivot point the arms move together.
  • the arms As the power cable is typically present at the rear of the device, the arms must be adapted in such a way to accommodate the arms moving together, but without interfering with the location of the power cable. This is usually done by creating a gap between the arms behind the pivot to allow the arms to open.
  • the structure In known hair straighteners, the structure is therefore typically, in a direction starting from the rear of the straightener towards the front: power cable socket/housing, adaptation to accommodate the opening of the arms, pivot pin, then arms and heatable plates. Therefore, a part of the length of the straightener is reserved solely for accommodating the power cable.
  • a housing of a hair styling apparatus the housing being adapted to house component parts of a hair styling apparatus, the housing comprising a first pivot to which an arm of a hair styling apparatus may be pivotally coupled, and a second pivot to which a second arm of a hair styling apparatus may be pivotally coupled.
  • each arm has a styling part and a handle.
  • the styling part has a heatable plate and/or surface that can be heated directly by a power source.
  • a power source When we say directly, we mean that it is the power source which generates the heat in the styling part as opposed to indirect heating through conduction from another part which is heated directly by the power source.
  • the first pivot is a separate pivot than that of the second pivot.
  • the axis of the first pivot is spaced apart from the axis of the second pivot.
  • the axis of the first pivot is parallel with the axis of the second pivot.

  • the housing is adapted to receive and retain a connector of a power cable.
  • the first and second pivot are symmetrically or approximately symmetrically arranged with respect to one another in the housing.
  • the axis of symmetry between the first and second pivot and the housing is aligned with or approximately aligned with the longitudinal axis of the housing.
  • the housing comprises a stop to prevent the power cable from being inserted past the stop in the housing.
  • the first and/or second pivot is located at or about the location of the stop in the housing.
  • first and/or second pivot are in alignment with the stop of the housing.
  • the stop extends inwardly into the housing from the first and/or second pivot.
  • the location of the pivots relative to the power cable is optimal as there is almost no distance between where the power cable ends, and the pivots begin.
