Abstract:
A hairstyling device including:a first jaw and a second jaw, hinged together by hinge means enabling them to pivot about a transverse hinge axis between a spread apart position and a close together position, an elastically flexible wire spring wound helically around said transverse hinge axis and having two radially projecting ends respectively adapted to bias said first jaw and said second jaw relative to each other toward said spread apart or said close together position, said hinge means including two parallel first perforated lugs on said first jaw spaced apart by a distance for stability, and two parallel second perforated lugs on said second jaw spaced apart by a distance appropriate for them to engage with respective opposite sides of said first perforated lugs, with a connecting spindle oriented along said transverse hinge axis and passing through said four perforated lugs to connect said jaws, a casing attached between said first perforated lugs, retained in a fixed position on said first jaw and forming an axial internal housing containing at least said helically wound portion of said spring, said first radially projecting end of said spring being in fixed bearing engagement with said casing or with said first jaw, said second radially projecting end of said spring exiting said casing to bear functionally against said second jaw and to bias it toward said close together position, said casing having ends with axial openings through which said connecting spindle can pass, in which device: said casing has a peripheral lateral wall with a generally cylindrical outside surface and its first end is extended by a rim on three of its sides to enclose at least in part the outside edge of the corresponding first perforated lug, said second end of said casing has no rim, and includes an end notch through which said second radially projecting end of said spring passes and in which it can move, and the other first perforated lug of said first jaw is oversized so that its outside edge is substantially continuous with the outside surface of the lateral wall of said casing.
