Definitions

  • the present invention relates generally to hand-held hair-styling appliances.
  • the present invention relates to a hair-curling appliance that is electrically heated and includes a motor to wind and unwind hair, to curl hair automatically.
  • Heated styling irons are commonly used to style hair to a wide variety of styles, such as by curling hair to impart a curl that does not naturally occur in the hair and by straightening hair to remove a kink or curl that does naturally occur in that hair.
  • a circular or semicircular-shaped curl can be created by wrapping hair about the outer surface of a heated cylindrically shaped curling iron tip.
  • Conventional curling irons include a curling mandrel comprising a generally cylindrical, elongated curling bar having a clamping member adapted to fit about a portion of the circumference thereof for at least a portion of the length thereof.
  • the curling mandrel is heated and a strand of hair is clamped against the bar by the clamping member.
  • Manual rotation of the entire curling iron winds the remainder of the strand of hair about the mandrel.
  • the heat in the mandrel alters the texture of the hair so as to curl it and after a predetermined amount of time, the curled hair is unwound.
  • One of the greatest difficulties encountered in the use of a curling iron is that of winding the hair about the mandrel.
  • Winding is typically a slow process in which the entire curling iron must be manually rotated. Such winding requires the use of two hands thereby making it difficult for a person to set their own hair. Rotating the entire device may also result in tangling of the power cord or the need for the power cord to have an independent swivel connection to the curling iron. Furthermore, since the degree of curl is dependent upon the temperature of the mandrel and the time of contact therewith, such winding should be rapidly or consistently accomplished in order to allow for uniform curl formation and to prevent burning of portions of the hair; however, this is difficult to perform when the device must be manually rotated. Accordingly, there is a need for a curling iron having a driven mandrel which will simplify the winding of the hair thereabout.
  • a hair curling iron for curling hairs which includes a handle for housing a motor and a first member having a first end rotatably coupled to the handle and selectively driven into rotation by the motor.
  • the first member has a second end spaced from the first end in a direction of elongation.
  • the hair curling iron further includes a heating element disposed within the first member and extending partially in the direction of elongation between the first end and the second end and a clamp mounted for rotation with the first member, the clamp having a closed position suitable for retaining the hairs and an open position suitable for receiving and withdrawing the hairs.
  • the hair curling iron also includes a clutch rotatably coupled between the motor and the first member wherein the first member and the clutch rotate for so long as the drag on the first member is less then a prescribed value.
  • FIG. 1 is a perspective view of a particular hair styling appliance structured in accordance with the principals of the present invention in a closed position;
  • FIG. 2 is a side view of the hair styling appliance of FIG. 1;
  • FIG. 3 is an exploded view of the styling appliance of FIG. 1 illustrating the major components thereof;
  • FIG. 4 is a bottom view of the hair styling appliance of FIG. Ia broken away to show internal components
  • FIG. 5 is a schematic diagram of a magnetic reed relay structured in accordance with a further aspect of the present invention.
  • FIG. 6 is a block diagram of control circuitry structured in accordance with a salient aspect of the present invention.
  • the present invention provides a curling iron constructed and suitable for heating and revolving hair into a curl which is set by the heat and contours of the curling iron.
  • curling iron 10 is shown in a closed position and generally includes a curling mandrel 12 and a handle 22.
  • the mandrel 12 includes an electrically heated male member 20. Additionally, mandrel 12 is motor driven to allow for rotation in a clockwise or counterclockwise direction to aid in curling of hah- around the mandrel.
  • the mandrel 12 includes an elongated, generally cylindrical male member 20 having a clamping element (female member 28) in contact with at least a portion of the circumference thereof.
  • the female member 28 is an elongated element which is preferably pivotally attached to a be2el 65 (FIG. 3) at a pivot point 34.
  • Bezel 65 is rotatably mounted between handle 22 and male member 20.
  • Female member 28 includes a projecting contact portion 29 which can be used to move the female member 28 to an open position wherein the curved portion thereof is pivoted out of engagement with the male member 20.
  • Projecting portion 29 is adapted to bias the female member 28 between the open position and a closed position to enable retention and release of one or more strands of hair.
  • a spring 62 can be connected to the female member 28 to movably bias the female member to the closed position and to resist movement of the female member to the opened position.
  • the handle 22 of the curling iron 10 can be provided with a power cable 40 (as shown) or can be battery driven.
  • the handle preferably includes a switch 16 for controlling power to the device.
  • An indicator light 30 is provided on housing 22 for indicating when the curling iron 10 is being heated.
  • Handle 22 further includes a motor switch 32 for initiating and terminating rotation of the mandrel 12.
  • the motor switch 32 may further be adapted to control the direction of mandrel rotation and it should be understood that different arrangements for the switches can be provided for control over heating and the motor.
  • curling iron 10 is configured so that the components thereof are disposed along a common linear central axis so as to provide a linear appliance.
  • a heat level selector switch can be provided to control an appropriate level of heat, typically a high or low level, and a motor speed selection switch can be provided so as to choose a desired mandrel rotational speed, typically a high, medium or low speed.
  • switch 16 is first turned on to heat curling iron 10. Once sufficiently heated, projecting portion 29 of female member 28 is depressed to open the female member 28. One or more strands of hair are inserted between female member 28 and male member 20, and projecting portion 29 is then released so as to retain the strands of hair.

  • the male member is preferably heated by the heating element 42 being located within it; however, in certain embodiments, male and female members 20, 28 are both heated or the heating element can be disposed in the female member 28.
  • the female member 28 has a spring 62 associated with the pivot point 34 thereof for purposes of biasing the female member 28 to its closed position. Release of a manual force on the projecting portion 29 allows the spring 62 to return the female member 28 to the closed position illustrated in FIG. 1.
  • motor 102 can be a DC motor.
  • the use of a DC motor confers several advantages in curling irons. DC motors are typically small sized and therefore allow for lightweight, compact appliances having a linear configuration. Additionally, use of DC motors allows for the ready, electrical control of motor rotation so as to provide for simple control of mandrel rotation. Surfaces 20 and 28 can grasp the trapped hair strands yet slide freely in a stroking manner from the scalp to the hair tips to accomplish a hair straightening effect. Slight rotation of hair styling appliance 10 as by cooking the user's wrist during the stroke, adds a flip to the hair.
  • hair styling apparatus 10 includes magnetic reed relay 500 for monitoring the revolutions of the motor 102, and consequently the revolutions of the mandrel.
  • a magnet 502 is connected to the motor shaft gear 504. As motor 102 drives the motor shaft gear 504 the magnet 502 comes into and out-of contact with the magnet reed relay 500. When magnet 502 reaches magnet reed relay 500 it causes contacts A and B to short circuit. Magnetic reed relay 500 can be connected to a microprocessor via contact A and B for detecting, for example, the short circuit of contacts A and B, thereby recording each revolution of the motor shaft gear 504.
  • Signals issued by the rotating shaft can comprise a magnetic field that selectively influences the magnet reed relay 500, e.g., to close the relay whenever the magnet is proximate the relay (e.g., in the 12 o'clock position as shown). Closure of the relay can interrupt power to the motor for a moment (as timed by suitable electronic circuitry or software) or until the switch 16 is activated again. In this way, the user can cease curling operations precisely at each complete rotation and be able to open female member and free the curled hair 89 from the hair styling appliance 10. More generally, circuitry can be provided to limit each actuation to a certain number of rotations or time of rotation for more precise curling control by the user.
  • a controller 700 with inputs for sensing closure of relay 500 via contacts A and B is provided.
  • control circuit 700 When the relay 500 is closed, control circuit 700 will output a signal on terminal 709 stopping the motor 102 for a predetermined time period set by RC circuit 703.
  • the motor 102 can be reactivated by triggering switch 16 or, otherwise, waiting a prescribed time interval upon which control circuit 700 will automatically reactivate the motor 102. Accordingly, the above described arrangement will permit controllable reactivation of motor 102 after each full rotation of the mandrel. After each full rotation, the user will be given the choice to stop further curling and free the hair held thereby or to continue curling for another complete rotation.
  • the relay described above can be set upon activating the motor and reset when a short circuit signal is generated after the mandrel has rotated 360°, or vice versa. If for any reason the reset condition does not occur, such as if motor 102 experiences a jam or a power off condition occurs prior to a full 360° rotation of motor shaft gear 504, the relay will remain set informing the microprocessor that the motor has not completed its rotation and may have been unnecessarily prevented from completing its cycle.
  • Embodiments of the hair styling technology described herein may be applied to various other hair treating or styling devices for shaping hair, such as, curlers, clamp curling brushes, steam curlers, hair rollers, hot hair rollers, hair straighteners, hair flatteners, and curling wands.
  • hair styling appliance with concave/convex heating surfaces of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes and modifications may be made thereto without departing from the invention in its broader aspects.
