ABSTRACT:
A hair curler includes a flexible central lattice element 2 flanked by hinged wing elements 3, 4 and having a flattened coil spring 5 mounted thereon under tension, thus tending to roll up the curler. The curler is held open in a first embodiment by a segmented strip 6 mounted on a wing element and only rollable in one direction, whereby it blocks rolling when the wing element is folded out and enables it when the wing element is folded over the central element. Rolling is prevented in a second embodiment by angle springs 9 and/or corner bands 10 connected at the hinge points of cross bars 8 extending across the central and wing elements, to thus hold the opened wing elements perpendicular to the main element.
