Abstract: The invention relates to hair rollers and provides for the use of a cylindrical tube rolled from a rectangular sheet of flexible material, the sheet having an outer edge which overlaps a portion of the tube. The tube has a pair of opposing transverse edges, each of which is engaged within a spiral groove formed in opposing caps. The caps are rotationally mounted on an elongated shaft, such that rotation of the disks causes advancement of the transverse edges within the spiral groove, changing the diameter of the outer tube, as desired.

Abstract: A hair-curling device for use in creating Z-shaped, angular or squared curls in the hair comprises a long double-hinged flat curler which includes an elongated flat rectangular main body and a pair of end flaps integrally attached to the ends of the main body by thin, narrow folding hinges. An elongated C-shaped locking receptacle extends along a free end of one end flap, and a cylindrical solid locking member extends along a free end of the other end flap. The hair is wrapped around the main body portion of the curler and the end flaps are then folded over the same side of the main body portion and interlocked in a snap fit by finger pressure applied to the end flaps. The end flaps, including the locking member and receptable, are together slightly longer than the main body of the curler, and the main body of the curler is slightly flexible laterally, so that the locking portions of the end flaps can be snapped together when the aligned end flaps are pressed down against the main body member.

Abstract: A hair curler system is disclosed which includes a selected length of flexible tubing used in conjuction with one or more flare members and a male coupling member to obtain a configurable assembly for rolling and looping a curl having different incremental diameters along its length. A first flare member is adapted to be partially inserted into one end of the tubing and has an outside diameter which tapers outwardly toward the flare member free end to obtain a graduated diameter along its length. The male coupling member is partially inserted into the opposite end of the tubing and terminates in a bulbous coupling element which is dimensioned and configured to be manually snapped through a reduced diameter neck region within the hollow interior of the first flare member such that, once a curl has been rolled onto the assembly, the assembly may be looped by snapping the coupling element through the reduced diameter neck region for retention during the perming process.
