Abstract: A hair removal device having a plurality of springs mounted on a rotary head and arranged to open and close during rotation, to trap and pluck skin hair over a relatively wide area. In a preferred embodiment, the rotary head multi-spring design is provided as a hand-held, motor-powered depilatory device having a plurality of compression coil springs each mounted in one of a set of tweezers.Each coil spring is operated by one of the tweezers, with the set of tweezers mounted in the rotary head so that at one tweezer end, the coil spring faces the skin and at the other tweezer end, a set of rollers contact a circular cam. During rotation of the rotary head, the rollers and cam arrangement cause each tweezer to alternately close and open, actuating the spring which traps hairs between it loops. The hair is plucked upon continued rotation of the rotor, and is released when the tweezer opens, and the next hair is trapped, etc.

Abstract: A hair removal device having a multiple-tweezer element arranged to pluck skin hair, by plucking action of a set of movable tweezers in a continuously repetitive fashion. In the preferred embodiment, the hair removal device is provided as a hand-held, motor-powered design having a hair plucking element which comprises a set of disc-shaped, fixed-position tweezer elements and an interleaved set of disc-shaped, movable tweezer elements mounted on a central shaft. The spaces formed between these elements are repetitively opened and closed by lateral push-pull sliding motion of the shaft against a cam which drives the movable elements in both directions in relation to the fixed-position elements, to trap and pluck skin hair. The design allows for an increase in the effective number of hair plucking operations over prior art designs since the spaces may be closed at any time, thus improving the mechanical efficiency without additional mechanical parts.
