Definitions

  • the present invention relates to hair styling irons, particularly electrical appliances for hair curling, having a winder for winding up hair.
  • One class of hand-held electric hair irons has a winder that is driven to rotate, or to rotate relative to, a barrel onto which a lock of hair is thereby wound for curling, such as described in US20130025620 and WO2013186547.
  • These prior art motorised curling irons have two jaws connected by a hinge so as to be moveable from an open position allowing the insertion of hair to a closed position to put the hair in contact with the heater and perform the curling treatment.
  • the principal advantages of these appliances are the speed and ease with which they allow hair to be styled, however there is an on-going need for improvements in the performance of this class of hair iron, particularly with respect to ergonomics.
  • the first jaw carries the barrel, and a hair-receiving opening in a head surrounding the barrel has a slot portion parallel to the barrel is opened and closed by movement of the second jaw relative to the first jaw.
  • this slot portion is too narrow to allow a user's fingers to into the heated chamber next to the barrel.
  • ease of use is compromised by the second jaw blocking access to the slot portion, requiring hair to be fed along a complex path, firstly in a longitudinal direction, and then transversely into the slot portion. There is a risk that some strands of hair will not be retained in the slot portion and wound about the barrel, resulting in incomplete styling of lock of hair.
  • the lack of symmetry or “handedness” of the appliance also means that it is not equally readily used both left- and right-handed. It would also be advantageous to have a simple and compact structure that can be manufactured for a lower cost. It is an object of the present invention to overcome or substantially ameliorate the above disadvantages or, more generally, to provide an improved curling iron.
  • a curling iron comprising:
  • a barrel having a proximal end mounted within the body and an opposing distal end, the body surrounding the barrel and enclosing a hair-receiving space between the barrel and the body;
  • an opening in the body comprising a circumferential portion extending about the distal end and a slot portion extending from the circumferential portion toward the proximal end, whereby opposing ends of a lock of hair passing through the hair-receiving space may extend from the circumferential portion and the slot portion.
  • the curling iron further comprises: a gating coupling connecting the barrel to the body to provide for relative movement between the barrel and the body between a closed position, in which the circumferential portion is closed to restrict movement of the lock of hair about the circumferential portion, and an open position, in which the circumferential portion is opened to allow a curled lock of hair to be withdrawn from the hair-receiving space.
  • a gating coupling connecting the barrel to the body to provide for relative movement between the barrel and the body between a closed position, in which the circumferential portion is closed to restrict movement of the lock of hair about the circumferential portion, and an open position, in which the circumferential portion is opened to allow a curled lock of hair to be withdrawn from the hair-receiving space.
  • the barrel substantially abuts the body in the closed position i.e. the barrel is very close to, or in abutment with, the body in the closed position.
  • a portion proximate to the distal end of the barrel preferably substantially abuts the body in the closed position.
  • the gating coupling may allow sliding movement of the barrel with respect to the body.
  • the sliding movement may be substantially perpendicular to a central axis of the barrel.
  • the gating coupling may comprise an elongate guide fixed to one of the body and the barrel and a block slidingly engaged with the guide and fixed to the other of the body and the barrel.
  • the gating coupling may comprise a pivot allowing relative pivoting movement of the barrel with respect to the body.
  • the pivot may have a pivot axis substantially orthogonal to a central axis of the barrel.
  • the pivot axis may intersect the central axis.
  • the barrel may fixed to a handle of the curling iron, so that the gating coupling provides relative movement between the handle and the body.
  • an operating lever is fixed to the body, for sliding or pivoting the body relative to the handle.
  • a switch may be actuated by movement of the operating lever for supplying power to a winder for winding the lock of hair about the barrel.
  • the curling iron further comprises a temperatures sensor for providing a temperature signal indicative of a temperature of the element and a controller that receives the temperature signal and controls power supply to the element to maintain the element within i) a predefined standby temperature range and ii) a predefined operating temperature range higher than the standby temperature range, and further comprising a winder for winding the lock of hair about the barrel, and feedback means connected to the controller for indicating that the winder is in operation, when power is supplied to the curling iron the controller actuates the element to maintain the element in the standby temperature range and when the feedback means indicates that the winder is in operation, the controller actuates the element to maintain the element in the operating temperature range.

  • a winder for winding the lock
  • the controller comprises a timer circuit and records an elapsed time from the activation of the feedback means that indicates that the winder is in operation, and after the elapsed time exceeds a predefined limit, the controller reverts to actuate the element to maintain the element in the standby temperature range.
  • a rotary encoder is connected to the controller to indicate the angular displacement of the winder, and after a predefined angular displacement is exceeded, the controller reverts to actuate the element to maintain the element in the standby temperature range.

  • the gating coupling 90 , 91 may allow sliding movement of the barrel 16 with respect to the body 10 .
  • the gating coupling may comprise a linear guide 90 , formed in the body 10 and elongated generally orthogonal to the axis 17 of the barrel 16 , the guide 90 receiving a sliding block 91 that houses the gear motor 21 .
  • the barrel 16 is mounted to this gear motor housing or sliding block 91 to reciprocate thererewith.
  • the barrel 16 is fixed to the handle (not shown in FIGS. 11-14 , see FIG. 21 ) and, in this manner, the body 10 may be mounted to the handle so as to allow the body to slide back and forth transversely to the axis 17 between open and closed positions.
  • the open position is shown in FIGS. 11 and 12 and shows that the barrel 16 may be disposed generally coaxially with the internal cylindrical wall 25 of the body 10 that surrounds it, so as to form the annular hair-receiving space 19 .
  • a lock of hair can be entered through the opening 18 into the hair-receiving space 19 and, once formatted into a generally helical coil, it can slide axially out from the hair-receiving space.
  • the closed position shown in FIGS. 13 and 14
  • the barrel 16 is disposed eccentrically, after being displaced along the guide 90 , transverse to the axis 17 .
  • the distal end 16 b may be disposed closely adjacent to, or in abutment with, the inner cylindrical surface 25 and providing contact along an axial line at a pinch point 92 .
  • the pinch point 92 is shown located at about 90° from the slot portion 18 b , but may generally be located at any angular position around the internal wall surrounding the barrel. In this manner, the circumferential portion 18 a is closed to restrict movement of the lock of hair in the circumferential portion past the pinch point 92 .
  • One or more springs may act between the barrel and body, to bias them to the open position.
  • FIGS. 15 and 16 illustrate an embodiment in which the circumferential portion 18 a is opened and closed by transverse sliding movement of the barrel 116 inside the body 110 .
  • the body 110 may be fixed to a handle (not shown).
  • the hair-receiving space 119 may be symmetrical about the axis 17 and taper to narrow in the axial direction toward the distal end 116 b .
  • the distal end 116 may be domed, as by a hemispherical surface 94 which may extend from the body 110 .
  • the hemispherical surface 94 may be disposed, in the closed position (see FIG.
  • line contact may be also provided along a curved line at pinch point 92 .
  • FIGS. 17-20 illustrate embodiments in which a pivot 97 having an axis transverse to the axis 17 of the barrel serves to provide the gating coupling that connects the barrel and body to turn relative to one another.
  • the pivot axis may be offset to one side of the axis 17 (see FIGS. 17 and 18 ) or may be disposed centrally to intersect the axis 17 (see FIGS. 19 and 20 ).
  • a torsion spring (not shown) may act between the barrel and body, to urge them to the open position, as shown in FIG. 20 .
  • FIG. 21 illustrates how the barrel 116 may fixed by a pivot 97 to one end of an elongate handle 111 of the curling iron, so that the body 310 pivots relative to the handle 111 .
  • a lever operator 113 fixed to the body 310 may extend adjacent to the handle 11 so that it can be readily operated, as by the user's thumb, for pivoting the body 310 .
  • a start switch 170 such as a microswitch, may be actuated by movement of the lever operator 113 for supplying power to a winder 101 for winding the lock of hair 20 about the barrel 116 .
  • a control circuit 105 of the curling iron controls the supply of power from a power supply 106 to a motor 107 and the heating elements 81 .
  • the gear motor 121 turns the winder 101 to wind the lock around the barrel 116 .
  • a temperature sensor 109 provides a temperature signal indicative of a temperature of the element 81 and a controller 108 receives the temperature signal and controls power supply to the element 81 , according a value preset by the user via the temperature control 111 .
  • the controller 108 maintains the element 81 either within i) a predefined standby temperature range or ii) within a predefined operating temperature range higher than the standby temperature range, as by 5° C.
  • Feedback means in the form of a rotary encoder 110 is connected to the controller for indicating that the winder motor 121 is in operation, and provides an indication of the angle through which the winder 101 has been turned.
  • the user may select one of a plurality of predefined standby temperature ranges as required according to the operation to be performed. Thereafter, the controller 108 supplies power to the element 81 to maintain the element 81 within the standby temperature range selected.
  • the barrel 116 is up to temperature the appliance is located toward the root end 20 a of a lock of hair 20 , so that the axis 17 is approximately aligned lengthwise with the lock of hair 20 , which is then inserted into the slot portion 18 b by a generally transverse relative movement.
  • the controller 108 boosts power to the element 81 and maintains the element in the higher operating temperature range.
  • the control circuit measures an elapsed time starting from actuation of the start switch 170 and after a predefined elapsed time or after a predefined angular displacement is exceeded (as determined from the rotary encoder 110 ), the controller 108 lowers the power level to the element 81 and reverts to actuate the element to maintain the element 81 in the selected standby temperature range.
  • the controller 108 may operate an alarm to indicate when the curling is completed, whereupon the user releases the lever operator 113 and a spring restores the lever operator 113 to an extended position and the body 310 to its open position.
