  • Patent number: 6425404
    Abstract: A hair curler device has a hair roller formed as a longitudinally extending body with a thicker intermediate portion around which a strand of hair may be wrapped and thinner arm portions on opposite sides thereof, and a hair-holding element having a pair of flat extended leg portions lying in a common plane which are joined together at their ends on one longitudinal side. The leg portions are spaced apart from each other by a gap extending to an opening on an opposite longitudinal side. The leg portions have respective non-linear surfaces facing opposite each other across the gap which have complementary shapes so as to define a first distance apart between the surfaces of the leg portions at the opening, a second distance apart at an intermediate position of the leg portions which is narrower than the first distance, and a third distance apart at the longitudinal side where the leg portions are joined which is about equal to the first distance.

  • Patent number: 4378814
    Abstract: The subject invention relates to a new and improved roller to produce curls in a strand of hair. More particularly, an improved hair roller is disclosed which includes a longitudinally extending body having an irregular cross section. In use, a strand of hair is wound around the body in a helical manner along the length thereof such that the diameter of successive turns varies. By this arrangement, when the strand is unwound, curls having various curvatures are formed. In the preferred embodiment of the subject invention, the roller includes an intermediate solid body having an oblate spheroid configuration. In addition, two sets of rods are provided which extend axially away from the opposed ends of the spheroid each terminating in a flange portion. Each set of rods is spaced apart to define a cross sectional diameter which is less than the maximum diameter of the intermediate solid body. A plurality of rollers may be utilized to create a naturally curly hair style.
