ABSTRACT:
The invention relates to an adjustable hair curler of general spool or roller shape with a pair of telescoping elongated tubes axially and rotatably movable relative to one another. A pair of nested larger diameter end caps is secured at each end of each tube with the roller generally resembling a spool. Each pair of caps includes a first cap with plural spiralled cam slots radiating from its center and a second cap nested in the first with a plurality of corresponding or equal number of straight cam slots radiating from its center. The nesting caps are rotatable relative to each other and the caps at each end are connected together by a plurality of toothed elongated curler segments. Each segment has structure at each end cooperating with the cap slots such that by rotating the end caps in opposite directions the segments are radially cammed to change the curler roller diameter. Additional structure locks the cap rotation at any desired roller diameter. All the components are molded plastic except the inner elongated tube is aluminum to absorb heat as a central thermal mass for curling hair on the curler roller.
