Definitions

  • the present invention relates generally to the field of hair removing devices and particularly to devices for uprooting facial hair.
  • a common method of removing unwanted hair at skin level is by shaving, by using a razor or other types of blades. Shaving however easily cuts the skin and may require daily shaves. The results are often rather short-lived. Besides, this is not a practical method for precisely removing individual hairs.
  • Another method is to apply chemicals to the skin for dissolving or burning out unwanted hair. Such depilation method may however cause chemical burns or allergic reactions. Besides, this treatment being on the surface, the results may be inconsistent or short-lived, requiring frequent applications of the chemicals. Using such chemicals on the face is generally too harsh.

  • the thread (102) under the tension is rested with a pressure, on the hairy surface (108) as shown in FIG. la.

Abstract

La présente invention concerne un dispositif (200) d'élimination des poils comprenant un élément formant base (301) pourvu de deux pattes allongées (302) s'étendant vers l'extérieur tout en maintenant un espace (310) entre ces dernières. Deux éléments souples allongés (311) forment une partie torsadée (304) entre leurs première et seconde extrémités (303), (305) qui sont fixées aux deux pattes (302). La partie torsadée (304) est positionnée dans l'espace (310), sous tension. Un élément mobile (306) s'étend vers l'extérieur depuis l'élément formant base (301) et peut bouger par rapport à l'élément formant base (301) avec des mouvements vers l'avant et vers l'arrière. L'élément mobile (306) entraîne la partie torsadée (304) à se déplacer vers l'avant pendant le mouvement avant et libère la partie torsadée (304) afin qu'elle se rétracte de manière résiliente pendant le mouvement inverse. La partie torsadée (304) peut retenir et extirper un poil (314) pendant le mouvement vers l'avant.
