Definitions

  • the present application relates to hair styling apparatus, and more particularly to electrical irons for shaping hair.
  • Hair curlers for example, are used to impart curls into hair. They may be used on dry hair but work best on wet hair. Steam may assist in setting the hair to the curl of the curlers.
  • Curling irons typically incorporate an electrical heating element to heat one or both sides of a smooth but curved pair of mating surfaces between which hair is placed to be curled. The hair may preferably be pulled through the interface of the mating surfaces of the curling iron to aid in curling the hair.
  • Other apparatus include hair straighteners and smoothers that operate much like curling irons, but have flat or curved, smooth mating surfaces which act more like a clothes iron to straighten and/or smooth, or curve or curl the hair when compressed against and pulled along the hair.
  • One or both surfaces may incorporate a source of dry heat, or a source of steam is provided with a trigger for discharging the steam through holes in at least one of the surfaces as an aid to hair styling.
  • This apparatus overcame a limitation of prior irons and straighteners that used untextured surfaces for engaging the hair, sometimes tangling the hair or requiring much additional brushing with another apparatus such as a brush to achieve the desired style.
  • the apparatus with pins reduced the time required to style the hair and the heat applied.
  • the prior apparatus could not conveniently be adapted for use without the detangling pins when desired. Users that wanted to use both flat untextured surfaces and surfaces with detangling pins had to either use two separate irons or change one or more plates making up the mating surface of the textured iron during use. Some of the convenience provided by the new iron was lost for some users.
  • an apparatus for styling air includes a hinged frame comprising two opposing arms and a hinge.
  • the apparatus includes a platen for engaging hair with a plurality of through holes arranged in a pattern, having a mounted surface against a first one of the arms and a free surface facing a second one of the two arms.
  • the platen should be thermally conductive and capable of engaging hair without snagging or undue friction, e.g., smooth.
  • the platen may be thermally coupled to an electrical heating element controlled by a thermal controller.
  • a pin carrier is interposed between the first one of the arms and the flat plate, comprising a plurality of pins coupled to a substrate and arranged in the pattern for inserting into the through holes.
  • a facing platen coupled to the second one of the arms may likewise be heated and may include a pattern of holes or recesses for receiving the detangling pins when the pins are extended and the two opposing arms are held together closely by a user.
  • the apparatus may further include a mechanism coupled to the pin carrier, movable between an extended state wherein the plurality of pins protrudes above the free surface and a retracted state wherein the plurality of pins are retracted below the free surface.
  • a user-operable actuator on one arm may activate the mechanism, allowing the user to extend and retract the pins as often as desired during hair styling.
  • the user is provided with a versatile apparatus useful as a detangling iron and as a flat iron, without needed to change out any components.
  • FIG. 1 is a perspective view illustrating an apparatus for styling hair with retractable detangling pins.
  • Fig. 2 is a cross-sectional view illustrating interior components of the apparatus shown in Fig. 1 .
  • Fig. 3 is an exploded perspective assembly view further illustrating interior components of the apparatus of Fig. 1.
  • Fig. 4 is a schematic diagram illustrating an electrical circuit for an apparatus as shown in Fig. 1 .
  • FIGs. 5A-B are simplified cross-sectional diagrams illustrating aspects of the retractable detangling pins and associated components, for a flat platen embodiment.
  • Fig. 6 is a simplified cross-sectional diagram illustrating aspects of the retractable detangling pins and associated components, for a contoured platen embodiment.
  • an apparatus 100 for styling hair includes a hinged frame 10 having two opposing arms 1 12, 1 14 joined by a hinge 124 that permits opening closing the two arms 1 12, 1 14 for capturing and releasing hair under treatment. While a pivoting hinge 124 is shown, other mechanisms for guiding movement of the arms 1 12, 1 14 may also be suitable.
  • the apparatus includes a perforated platen 108 (Figs. 1 , 3) having a plurality of through holes 1 10 (Fig. 3) arranged in a pattern.
  • the perforated platen is shown smooth on its upper surface to allow hair to pass over the perforated platen 108 without snagging or undue friction, non-smooth contours such as ridges that do not snag hair may also be useful.
  • the bottom of the perforated platen 108, its "mounted surface” need not be smooth and may include various non-smooth mounting features, partially visible in Fig. 3.
  • the mounted surface (bottom) of the perforated platen 108 is mounted against a first one of the arms, with its free surface facing a second one of the two arms as shown in Figs. 1 , 3.
  • the perforated platen may be coated with a non-stick high-temperature coating, for example, a ceramic, fluoropolymer (e.g., polytetrafluoroethylene), or chloro- fluoropolymer for greater smoothness and protection from oxidation.
  • a non-stick high-temperature coating for example, a ceramic, fluoropolymer (e.g., polytetrafluoroethylene), or chloro- fluoropolymer for greater smoothness and protection from oxidation.
  • a non-stick high-temperature coating for example, a ceramic, fluoropolymer (e.g., polytetrafluoroethylene), or chloro- fluoropolymer for greater smoothness and protection from oxidation.
  • the perforated platen as shown in Figs. 1 and 3 includes a pattern of cylindrical holes (i.e., holes with cylindrical walls)
  • the perforations may be of any configuration that accommodates the detangling pins inserted through the perfor
  • the apparatus 100 may further include a pin carrier 106, 106' interposed between the first one of the arms 1 14 and the perforated plate.
  • the pin carrier may be made of any suitable structural material in any useful shape. While dual pin carriers 106, 106' are illustrated in Fig. 3, any useful number of pin carriers may be used, for example, one, two, or three.
  • the dual pin carriers 106, 106' may be joined by clips 132 at or near ends thereof, forming an integrated pin carrier 107.
  • inner rows of the pins 104' may be spaced apart further than the outer rows of pins 104; for example, about 1 .5 to 3 times further apart, such as about twice as far apart.
  • Each of the two separate pieces 106, 106' may be positioned relative to the perforated platen 108 so the first 104 of the two rows is along and closer to an edge of the perforated platen than the second 104' of the two rows of pins.
  • the pattern of through holes in the perforated plate 108 may include a row of more closely-spaced holes along each long edge of the smooth plate, and two or more rows of more widely-spaced holes there between, as shown in Fig. 3.
  • Each pin carrier 106, 106' includes a plurality of pins 104, 104' coupled to a substrate and arranged in the pattern of perforations for inserting into the through holes.
  • the pins 104, 104' should be smooth enough for detangling hair, for example a surface roughness of about 3 micrometers or smoother and made of a ductile and/or tough structural material capable of operating in the expected high-temperature environment. Suitable materials may include, for example, stainless steel, uncoated or coated with a high-temperature friction- reducing coating as described for the perforated platen 108, structural ceramics, or similarly tough materials.
  • the detangling pins illustrated in Figs. 1 , 3 are cylinders with rounded, tapered, blunt or pointed ends, about 0.5 to 1.5 mm in diameter and about 4 to 8 mm long; however, other sizes and shapes of pins may also be useful.
  • the apparatus 100 may further include a mechanism 149 coupled to the pin carrier 106, 106'.
  • the mechanism 149 may be an assembly of multiple components, for example, a slider 138, a link 148, a sliding actuator 144, and a frame 142.
  • the slider 138 includes sliding bearings 136 of low-friction material at or near its four corners. The bearings 136 facilitate smooth sliding of the slider 138 relative to the integrated pin carrier 107, under a pushing or pulling force exerted by the user against the manual actuator 144 in a receiver of the first arm 1 14. The pushing or pulling force is transmitted to the slider 138 by the link 148.
  • the frame 142 may include linear cams 140, also called ramps, that a lower surface or additional bearings of the slider traverses as it slides back and forth.
  • the cams or ramps convert linear motion parallel to perforated plate 108 into linear motion perpendicular to the perforated plate 108, pushing the pin carrier 107 towards the perforated plate 108 and compressing resilient spring members 102 (for example, coil springs).
  • the resilient members 102 impart a return force when the slider moves in the opposite direction and back down the ramps 140.
  • the mechanism 149 and pin carrier 107 are movable between an extended state wherein the plurality of pins protrudes above the free surface and a retracted state wherein the plurality of pins is retracted below the free surface of the perforated plate 108.
  • the resilient springs 102 bias the pin carrier towards one of the extended state and the retracted state (bias towards the retracted state is illustrated).
  • the ramps 140 are disposed against the pin carrier 107 by the slider 138 and springs 102, positioned for transforming motion of the pin carrier 107 parallel to the perforated platen 108 into motion perpendicular to the perforated platen.
  • Other reciprocating mechanisms may also be used, instead of the illustrated sliding linear-cam mechanism.
  • the apparatus may further include a water reservoir 1 17 for producing steam (Fig. 2) and a steam control button 1 18 (Fig. 3).
  • Other components may include, for example, the second arm 1 12, a keypad 120 for power and temperature control, and hinge pin bearings 122, 156 in the second and first arms 1 12, 1 14.
  • a hinge pin 124 mounted through a wire guide 126 completes the hinge assembly.
  • AC power may be supplied via a power bushing 130 and coupling 128.
  • Wire guide channels in the guide 126 may be covered by one or more cover plates 146.
  • a lower screen 152 ventilates an interior of the first arm 1 14.
  • a fuse assembly 154 may provide overload protection.
  • Upper and lower radiative housings 1 16, 1 15 help radiate excess heat and prevent skin contact with hot surfaces.
  • the perforated platen 108 and/or a second platen are in thermal conductive communication with a resistive heating wire or element under the control of a heating circuit.
  • a heating circuit 400 includes a platen 412 thermally coupled to a resistive (or inductive) heating element 414.
  • One or more temperature sensors 416 are likewise coupled to the platen 412.
  • An AC power source 410 (e.g., via a connector to a wall socket) is coupled to a power controller 408, that supplies DC power to digital components of the circuit 400 and modulates power to the heater 414 under control of the microprocessor (or microcontroller) 402.
  • the microprocessor 402 runs a control and user interface program that accepts inputs from the temperature sensor (or sensors) 416 and keypad 404 and provides a digital or analog output signal to the power controller 408 that controls energy supplied to the heater 414.
  • the microprocessor 402 controls a digital readout 406 that informs the user of the platen temperature as measured by the sensor 412.
  • the apparatus 100 may include a second platen 103 mounted to the second arm opposite to the smooth plate (Fig. 2).
  • a platen-pin assembly 500 may include a second platen 502 mounted as shown for platen 103 in Fig. 2 may include a pattern of recesses 510 matching the pattern of pins 504 fixed normal to the pin carrier 506 and the pattern of through holes in the perforated platen 508.
