Depilation apparatus with a housing and a depilation member for gripping hairs on human skin and pulling the hairs from the skin comprises a vibration member for exerting mechanical vibrations on the skin. Such mechanical vibrations have an anaesthetizing effect on the skin so that pain sensations caused by the process of pulling hairs from the skin are relieved. The vibration member comprises flexible protrusions which have been disposed on a carrier. In this way, the mechanical vibrations are introduced into the skin in distinct concentrated positions on the skin.

Depilation apparatus with vibration member

A depilation apparatus including a number of pinching discs (35) which are coupled to a drive shaft (7) in positions which are mutually rotated through 120.degree. about the drive shaft (7) is provided. Each pair of adjoining pinching discs (35) is pivotable under the influence of a compression member (83) into a pinching position in which two cooperating pinching surfaces (67, 63) exert a pinching force on one another. The pivot axis (113) of each pair of pinching discs (35) is determined by a stud part (55b) of a bipartite stud (55) of one of the two pinching discs (35) and by the mutually facing steps (41) of the two pinching discs (35). The cooperating pinching surfaces (67, 63) are supported on either side in the pinching position by the stud parts (55b) and (55a), respectively, of the bipartite studs (55) of the adjoining pinching discs (35), so that a substantially straight force transmission path is created in the pinching position. Each pair of cooperating pinching discs is provided with a delaying stud (59) by which the pinching position is temporarily delayed after tilting of the pinching discs (35) about the pivot axis (113). Furthermore, each pair of cooperating pinching surfaces (67, 63) is provided with two nose-shaped combs (73, 71) which are bent into a hair-trapping funnel.

Disc-type depilation apparatus with force transmission studs

The invention relates to a depilation apparatus, in which a driving roller (3) and a drive roller (4) are provided with tooth means (5, 6) and form a roller pair, the rollers performing a rotary movement which is directed into the interior of the apparatus at the location where they interengage circumferentially. The driven roller (4) of each roller pair has teeth (5) along its entire circumference but the driving roller (3) has teeth only along part of its circumference, so that the rollers intermesh only during part of a revolution of the driving roller.
