  • Patent number: 10772406
    Abstract: A hair styling device is described, for waving hair by forming a length of hair into a wave form. A first forming member, a second forming member and a third forming member are located within a chamber of the device. There is a first hair-receiving region between the first and second forming members and a second hair-receiving region between the second and third forming members. A first driving member drives a portion of the length of hair into the first hair-receiving region and a second driving member drives another portion of the length of hair into the second hair-receiving region. The first and second driving members move independently and sequentially so as to reduce the tension applied to the length of hair.

  • Patent number: 9872549
    Abstract: A hair styling device comprising two hinged arms able to move relative to each other for the receiving and shaping of a strand of hair. Each arm carries a shaping plate on its side facing the other arm. These shaping surfaces making contact with the hair strand being styled. The hair being styled is pulled past these shaping surfaces. One of the two arms has a hair support on its side carrying the shaping plate. The hair support is arranged at a spacing from the shaping surface of the other arm, so that the other arm can be introduced into an arm support between the hair support and the shaping surface of the shaping plate of the arm carrying the hair support. The shaping plates of the two arms which cooperate with each other for the hair styling can move relative to each other in the manner of scissors.

  • Patent number: 6014977
    Abstract: A curling iron includes a handle that supports a heating element that projects out from the handle. An adjustable barrel is also carried by the handle and surrounds the heating element such that the heating element is substantially centrally disposed in the barrel. The barrel is adjustable between first and second positions where the diameter of the barrel is larger in the second position than the first position. The heating element remains centrally disposed in the barrel in the first and second positions. The barrel is adjusted by moving the clip assembly that is connected to the barrel. The clip assembly includes a clip that accommodates the changes in barrel diameter. A plurality of support elements are connected to the handle and adjustably support the barrel. The support elements include springs that support shoes that slidably engage the barrel.

  • Patent number: 5934293
    Abstract: A hair iron for straight permanents includes a pair of arms joined by a pivot to enable opening and closing, and hair pinching parts formed in such a way that they approach and leave in accordance with the closing and opening of the arms. On both hair pinching parts, convex and concave arrays in waveform cross sections are formed in the arms so as to engage each other when the arms are in the approaching position. The convex and concave arrays are arranged in such a way that, along the full width of the hair pinching part, the hair tip region is dense with a short waveform pitch and the hair root region is sparse with a long waveform pitch.

  • Patent number: 5832939
    Abstract: An improved hair waving appliance is disclosed. The disclosed hair waving, appliance includes a pair of W-shaped arms that pivot in relation to one another in a scissors motion. One disclosed W-shaped arm comprises a center raised heater prong bounded by a trough portion on each side. The outer edges of each trough portion may include a curved lip to prevent undue damage to hair. Another W-shaped arm is disclosed comprising two raised heated prongs separated by a trough portion. The disclosed arms fit together to form an interstitial gap therebetween such that more even temperatures are provided over the entire surface of each arm. The disclosed prongs might be of a variety of cross sections, including ovoid and substantially circular. Further disclosed is a plurality of stand members protruding downwardly from the appliance for resting the appliance upon a substantially horizontal surface without causing any heat damage thereto.

  • Patent number: 5799671
    Abstract: A curly hair curing iron having a jerking portion which does not exert a severing action on the hair and a stretching portion for making the hair straight. The iron is a scissors type iron having a rod housing with heaters therein. The inlet side constitutes the jerking portion having a strong gripping force. The outlet side constitutes the stretching portion having a weaker gripping force than the jerking portion. The jerking portion includes convex portions 8, 9 and 10 on one rod, and plane portions in engagement with the convex portions on the opposite rod. The stretching portion has a plurality of convex portions 11 on one rod which are square or trapezoidal in section and a plane on the other rod. Both the convex portions and the plane portions on both the jerking portion and the stretching portion are formed of an elastic material.

  • Patent number: 5783800
    Abstract: A hair braiding tool for fusing the end of a braid of synthetic fibers includes a first elongated member having at least one substantially semi-cylindrical transverse groove formed in a surface thereof with the groove having an open end and a closed end and a second elongated member pivotally connected to the first elongated member and having at least one substantially semi-cylindrical transverse groove formed in a surface thereof with the groove having an open end and a closed end. Upon bringing the first and second members into engagement with each other, the semi-cylindrical grooves therein mate with each other to define a cylindrical passage having an open end and a closed end for receiving a braid end therein. An electrical heating element is disposed in contact with the closed end of the cylindrical passage for trimming and fusing the braid end.

  • Patent number: 5119846
    Abstract: An apparatus for waving the hair comprises a pair of snap-together complementary pieces made of resilient plastic. The pieces when fitted together define a sinuous or swirled path between them. When the pieces are snapped together over a strand of hair, the strand is held in a sinuous waving shape for imparting a "perm". A first piece includes a cylindrical roller and two partial cylindrical cages, resembling those used in ordinary hair rollers except for their mutual attachment and the angular cut from each cage. The second, mating piece includes one cage and two rollers. In both pieces a cage is tangentially attached to a roller at two places. Each roller or cage on one piece mates to a respective cage or roller on the other piece. The pieces snap together by forcing the middle roller of the first piece between the two rollers of the second piece into the cage of second piece; the two rollers of second piece simultaneously snap into the two cages of the first piece.

  • Patent number: 5025850
    Abstract: A hair crimping device for use in setting human hair includes a pair of complementary formed triangular wave form members dimensioned for nesting engagement. A base plate is secured to a first tiangular wave form member and includes an elongated projecting handle. A plurality of resilient tabs extend upwardly at opposite ends of the first triangular wave form member and a plurality of apertures are formed in a second trangular wave form member and dimensioned for engagement with the tabs for securing the first and second triangular wave form members in nesting relation. In use, an individual's hair is clamped between the triangular wave form members, thereby assuming a triangular wave form configuration. A plurality of holes are formed through each of the triangular wave form members for establishing fluid communication with hair clamped therebetween.
