  • Patent number: 6619296
    Abstract: A hair article according to the invention comprises two jaws which are elongate in a direction of extension and each include a rigid body having a principal part which is elongate in the direction of extension and parallel transverse excrescences to which is attached an elastically flexible structure parallel to the direction of extension, offset from the principal part of the rigid body and including projecting parts oriented toward the second jaw. A lighter hair article, in which the flexibility of the elastically flexible structure improves the hold in the hair, is thus produced.

  • Patent number: 6354307
    Abstract: A hairstyling device includes two jaws hinged together about a transverse hinge axis around which a helical spring is helically wound. The spring is contained in an opaque casing attached to the first jaw and which has an end notch through which one second radially projecting end of the spring passes to bear against the second jaw. The casing is in one piece, with a rim at one end covering the outside edge of a first perforated lug to prevent rotation. Its other end has no rim but is associated with another first perforated lug which is oversized and has an outside edge substantially continuous with the outside lateral surface of the casing.

  • Patent number: 6189544
    Abstract: A hair grip has two elongate one-piece jaws connected by a spring-loaded hinge and delimited by two respective first longitudinal edges, two respective other longitudinal edges. The respective other longitudinal edges each carry spaced curved penetrating teeth extending the jaw on the side opposite the first edges and concave sides of which face toward the teeth of the other jaw to penetrate the hair. These pluralities of penetrating teeth conjointly form a longitudinal succession of pairs of teeth of each respective plurality of teeth. The longitudinal succession of pairs of teeth includes at least one pair of bearing teeth whose end areas are disposed and oriented to rest on or slightly below the surface of the hair, and at least one pair of penetrating teeth offset from each other along said other longitudinal edges of the jaws and which can cross over to penetrate in the hair.

  • Patent number: 5979467
    Abstract: A hair clip of the invention comprises two jaws hinged together by hinge means. At least some of the teeth are relatively narrow in the vicinity of their base and can have a maximal width in the central area of the tooth and be relatively narrow in the vicinity of the free end of the tooth. This improves the retention of the clip in the hair.

  • Patent number: 5842485
    Abstract: The hairclip of the invention comprises two elongate branches hinged together at their first ends about a transverse hinge axis, with retaining lugs or a retaining spring for selectively and separably fastening them together at their second ends. Each branch has curved teeth extending laterally from the first lateral edge, curving towards the other branch and interdigitated with the curved teeth of said other branch. This improves the retention of said hair in the hairclip.

  • Patent number: 5842482
    Abstract: A hairstyling device includes, according to the invention, two jaws hinged together by hinge means including a hinge pin and a coil spring wound in a spiral around the pin. The spring is contained in an opaque casing attached to the first jaw, and incorporating a slot through which the second end of the spring passes to bear against the second jaw. This facilitates assembly of the hairstyling device, and enhances its esthetic appearance.

  • Patent number: 5664591
    Abstract: A hair clip includes a first jaw operable by a first opening lever and hinged to a second jaw operable by a second opening lever. The hinge is provided by perforated lugs respectively projecting beyond inside surfaces of intermediate connecting areas between the levers and the jaws through which passes a connecting pin defining a transverse hinge axis. Two open annular springs disposed coaxially around the hinge axis pass through corresponding openings in the levers and bear in corresponding housings on outside surfaces of the jaws. The annular springs cover the perforated lugs. A tubular member covers the connecting pin between the two sets of perforated lugs. The resulting clip has a posterior side of considerably improved esthetic appearance.
