Definitions

  • the present invention relates to heated irons having jaws between which hair can be clamped for straightening, and a clamp for holding hair wound about the closed jaws for waving, and particularly to irons having a locking mechanism for locking the jaws together in this waving configuration.
  • WO 2006/044570 describes an iron having a pair of heated jaws between which hair can be clamped for straightening, and a clamp for holding hair wound about the closed jaws for waving.
  • a locking mechanism is provided locking the clamp to a pivoting jaw, such that the clamp and jaw pivot together in a straightening configuration and releasing the clamp from the pivoting jaw in the waving configuration.
  • the locking mechanism however does not lock the jaws closed together in the waving configuration. It is an object of the present invention to meet the above needs or more generally to provide an improved hair straightening and waving iron.
  • a hair styling iron comprising:
  • the invention provides a hair styling iron comprising:
  • the iron further includes a detent for holding the pivot in the first position and second position.
  • the inner faces of the jaws are substantially flat.
  • the outer faces of the jaws are preferably convex and the clamp face concave such that with the pivot in the second position hair wound about both jaws can be held against the jaws by the clamp for waving.
  • the first jaw is rigidly fixed to the handle, and further including a spring biasing the clamp toward the first jaw, the clamp having a lever portion on the opposite side of the pivot from the clamp surface, such that pressing the lever portion toward the handle pivots the clamp face away from the first jaw.
  • the iron preferably further comprises a spring biasing the pivot to one of the first and second positions, the detent including a slider fixed in a slot in the handle, the slider having an outer side configured to be manually engaged and an opposing inner side for engaging the pivot, the inner side including a ramp inclined to the axis of the pivot for moving the pivot axially.
  • This invention provides a hair straightening and waving iron with a locking mechanism for locking the jaws together which is effective and efficient in operational use, and which has an overall simple design and a small number of parts which minimizes manufacturing costs.
  • an electric hair styling iron 10 comprises a handle 11 having a convex cross-section and formed from upper and lower elongate shell mouldings 11 a, 11 b.
  • a power cord (not shown) may extend from the end of the handle 11.
  • a first jaw 12 is rigidly fixed to the handle 11 and has flat inner surface 12a and cylindrical outer surface 12b.
  • Both jaws 12, 13 are elongate and hollow, their distal ends being closed by tips 14, 15 respectively, made of thermally insulating material.
  • a hair waving clamp 16 has a clamp portion 16a with concave cylindrical clamp face 16b shaped to conform to the cylindrical face 13b.
  • the clamp 16 is attached by the pivot 19 to the handle 11.
  • a lever portion 17 extends from the clamp portion 16a to the opposite side of the pivot 19 such that pressing the lever portion 17 toward the handle 11 pivots the clamp face 16b away from the first jaw 12, thereby either opening the jaws 12, 13 in a straightening configuration ( Fig. 2 ) or else opening the clamp 16 in a curling configuration ( Fig. 3 ).
  • a torsion spring 22 is fixed to the handle 11 and located under the lever 17, biasing the lever 17 to close both the clamp 16 and second jaw 13.
  • a locking mechanism includes a longitudinally moving slider 18 or actuating member on a side of the handle 11 adjacent its inner end.
  • the slider 18 actuates the locking mechanism and also provides a detent, it is moveable between an outer position ( Figs 1 and 2 ) wherein second jaw 13 and clamp assembly 16 are locked together (the straightening configuration), and an inner position ( Fig. 3 ) wherein the first and second jaws 12, 13 are locked together (the curling configuration).
  • the pivot 19, as shown in Fig. 4 is substantially cylindrical with projecting key portions 30, 31, 32, 33, 34, 35, 36, 37 formed thereon.
  • the key portions are symmetrically arranged in pairs 30/31, 32/33, 34/35, 36/37 the projections of each pair being on opposing sides of a central plane 20, the pairs being spaced apart longitudinally.
  • the pivot 19 extends through apertures 24, 25, 26 in the first jaw 12 (which is fixed to the handle 11), the second jaw 13 and the clamp 16 respectively.
  • the apertures 24, 25, 26 are configured to receive the pivot 19 in a sliding fit and have respective cylindrical faces 24a, 25a, 26a and keyway portions 24b, 25b, 26b on opposing sides of the central plane 20 for receiving the key portions 30, 31, 32, 33, 34, 35, 36, 37.
  • Two stop pins 41 are held in an interference fit in apertures 43 in the jaw 12, and slidably received in part-annular slots 44, 45 in the second jaw 13 and clamp 16 respectively, for limiting the angular displacement of the jaw 13 and clamp 16.
  • FIG. 6 shows that the first jaw 12, second jaw 13 and clamp 16 are generally U-shaped in transverse section, the pivot-receiving aperture 24 extending through two flanges 12a, 12b of the first jaw 12, pivot-receiving aperture 25 extending through two flanges 13a, 13b of the second jaw 13, pivot-receiving aperture 26 extending through two flanges 16a, 16b of the clamp 16.
  • Fig. 7 illustrates the longitudinally extending element 40 received within the pivoting jaw 13.
  • the spring is extended and the pivot 19 is in a first position wherein the key portions 30, 31, 36, 37 are received in the apertures 26 in the clamp 17, rotationally fixing the pivot 19 to the clamp 17.
  • the key portions 32, 33, 34, 35 are received in the apertures 25 in the second jaw 13, likewise rotationally fixing the pivot 19 to the second jaw 13.
  • the key faces 30a, 31a, 36a, 37a on the pivot 19 engage the key faces 25d, 26d, 25e, 26e on the second jaw 13 and the clamp 17 for connecting the second jaw 13 and the clamp 17 together for pivoting relative to the first jaw 12.
  • the slider 18 has an inclined ramp face 41 which engages the end of the pivot 19 when the slider 18 is moved to its inner position, thereby displacing the pivot 19 to a second position shown in Fig. 9 . In this manner slider 18 provides a detent for holding the pivot 19 in the first position or second position.
