Abstract

A hair-curler of the non-electrothermal type comprising a cage-like tubular core formed at its one end with at least two slots intersecting each other at the center of the end, a hollow cylindrical cover of cellular synthetic resin covering the tubular core, a frame support fitted in the other end of the tubular core and rotatable relative to the tubular core, and a rectangular holding frame having one end pivoted to the support and the other end provided with an engaging projection detachably engageable in one of the slots so that the hair is wound onto the cover while rotating the tubular core relative to the holding frame and is then held to the cover with the holding frame by engaging the projection in the slot. The hair can be readily effectively held in place by the holding frame in the desired angularly displaced position of the tubular core without using a separate hairpin for holding the hair.

Dependent claims

A hair-curler comprising a cage-like tubular core, a hollow cylindrical cover of cellular synthetic resin covering the tubular core, and a rectangular holding frame pivotally connected to one end of the tubular core and provided with an engaging projection detachably engageable in the other end of the tubular core;

the tubular core:
(1) being formed at its one end with at least two slots intersecting each other at the center of the end for engaging the engaging projection of the holding frame, the slots being formed in an outwardly bulged center portion of the end which provides a guide surface for the engaging projection of the holding frame;
(2) having at its longitudinal midportion a flexible portion bendable with the cover when the tubular core is subjected to an external force at its opposite ends;
and (3) having a frame support fittingly retained on the inner peripheral wall of the other end of the tubular core against displacement longitudinally of the tubular core but rotatable circumferentially of the tubular core;
and the rectangular holding frame being integral in its entirety and surrounding the cover.
