  • the heating plate includes at least aluminium Brief Description of the Drawings
  • Figure 1 shows a perspective view of a first embodiment first and second heating plates fitted to a hair straightener
  • Figure 2 shows a further embodiment of a heating plate wherein the heating plate is detached from a hair straightener, the heating plate including first and second releasably attachable edges to enable selectably interchangeable combinations of edge shape profiles to be provided,
  • Figure 3 shows a prior art squared-edge heating plate engaging with a hair line of a section of hair to be straightened whereby it is unable to engage substantially uniformly with the bulk of roots of the hair section,
  • Figure 4 shows the first embodiment heating plate engaging with the roots of a section of hair to be straightened whereby the tapered edge substantially complements a hair line contour of a hair section to be straightened
  • FIG 1 corresponding first embodiment heating plates (1a, 1b) are shown in perspective view fitted to upper and lower frames (2a, 2b) of a hair straightener (2)
  • the heating plate (1 b) includes a substantially planar hair engagement surface (1c) and first and a second edges (1d,1e) defining a periphery of first end (1f) of the hair engagement surface (1c)
  • the upper and lower frames (2a, 2b) are rotatably coupled to each other around a hinge (2c) whereby the heating plates (1a, 1b) are able to be rotatably clamped together around a section of hair (3) during straightening
  • Figure 1 shows the upper and lower frames (2a, 2b) arranged in the opened position prior to clamping upon the section of hair (3)
  • Surfaces of the upper and lower frames (1a, 1b) upon which the corresponding first and second heating plates (1a, 1b) are fitted include substantially similar shape profiles such that the hair straighter is relatively streamlined
  • outward-facing surfaces of the first and second frames (1a, 1b) include substantially curved contours which further provide the hair straightener with a relatively streamlined shape
  • the hair straightener (2) includes a power cord (2g) for connection with a mam power supply
  • the power cord (2g) includes a ringlet (2b) to allow the hair straightener (2) to be suspended from a hook if desired
  • the hair straightener (2) further includes a control switch (2d) for controlling the temperature of the heating plates (1a, 1b) and hence the amount of heat that may be transferred to the hair (3) in use
  • the hair straightener (2) also includes an on/off button implemented by way of a sliding switch (2f) disposed on the upper frame (1a) of the hair straightener (2)
  • the first and second edges (1d,1e) of the hair engagement surface (1c) each include substantially concurve-shape profiles which cooperatively, and substantially, form a bullet-head shaped end profile of the periphery of the hair engagement surface (1c)
  • the tapered shape profile of at least one of the first and second edges (1d,1e) may assist a user in positioning the hair engagement surface (1c) in closer and more uniform contact with the roots (3) at the hair line (3c) of a section of hair (3) to be straightened Consequently, the hair engagement surface (1c) may then be applied more uniformly substantially along an entire length of the hair (3) from the roots (3) to the tips (3d)
  • the deficiency in the prior art is depicted in Fig 3 in which the squared-edge (4a) of the prior art heating plate (4) is unable to substantially engage in uniform fashion with the roots (3) at the hair line (3c)
  • the tapered-shape profile allows a user to selectively angle only the first end (1f) of the hair engagement surface (1c) inwardly towards the roots (3) to enable closer proximity and more uniform contact with the roots (3) of the hair (3) to be straightened whilst at the same time enabling an unused region (1g) of the hair engagement surface (1c) to be positioned outwardly away from the person's head (not shown) in use in order to alleviate the risk of inadvertently burning the head
  • the relatively dangerous proximity of a substantially rectangular-shaped prior art heating plate (4), when engaging with the hair (3) - that is, the unused portion (4b) of the prior art heating plate (4) extends linearly in close proximity to the head where inadvertent burning may arise
  • the tapered-shape profile of at least one of the first and second edges (1e,1e) of the heat engagement surface (1c) may assist in sectioning or partitioning the hair (3) due to the relatively streamlined configuration of the tapered-shape profile which is relatively easier to penetrate through the hair (3) during sectioning
  • the non-streamlined squared ends of the heating plates do not lend themselves towards ease of partitioning or penetrating through the person's hair
  • the bullet-head shape profile is substantially symmetrical relative to an elongate axis (1h) of the hair engagement surface (1c)
  • a second embodiment heating plate (5) is shown in which a first edge (5b) of the heat engagement surface (5a) includes a shape profile which is substantially asymmetrical with a shape profile of a second edge (5c) Specifically, the first edge (5b) includes a triangular-shape profile whilst the second edge includes a concurve shape profile [0044]
  • Alternative combinations of first and second edge shape profiles may be employed in other embodiments.
  • the first edge may include a concurve-shape profile whilst the second edge may include a concave-shape profile, or, the first edge may include a triangular shape profile whilst the second edge may include a concave-shape profile.
  • the heating plates (1 ,5) described in relation to the first and second embodiments are made from aluminium which provides suitable heat conductivity from the heating plates (1 ,5) to the hair (3) in use. More specifically, the heating plates (1 ,5) are formed by punching the heating plates from a sheet of aluminium or other suitably heat conductive metal.
  • the first and second edges of the heating plate are releasably attachable to a frame of the hair straightener using a suitable attachment means.
  • the attachment means may include screwing the heating plate into position upon a support surface of the lower frame.
  • first and second edges may conveniently enable selectable interchanging of first and second edges having different shape profiles each of which may be particularly suitable for use with different head shape contours and/or different orientations of the person's hair to be straightened.
  • the selectable interchangeability of first and second edges may provide commercial advantages in that the hair straightener may be conveniently sold separately to the heating plates so as to enable more flexible user-choice in selecting first and second edges which are of specific use to the user.
  • a user may conveniently purchase a suitable replacement first or second edge for the hair straightener.
  • the heating plate may have different shape contours formed into the heating plate at the point of manufacture.
  • selectable interchangability may not be available, however, the different shape contours on each edge of the heating plate may still provide great flexibility in use when straightening the hair of different persons.
