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 cup-like rotor formed with two concentric supports. A plurality of compression coil springs are mounted in in freely rotatable fashion on pins extending radially between the supports. The springs have normally open loops with spaces between them along the pin length. A cam is arranged proximate the pins such that when the rotary head rotates about a shaft, the pins slide radially between the supports in accordance with the cam shape. Radial movement of the pin forces a shoulder formed at one end against the end of the spring, compressing and closing its loops. When passed over the skin, the loops of each spring mounted on the rotary head rotate freely on the skin, reducing friction, while the loops open and close over a wide area, and skin hair in this area is grasped and plucked as the loops close, performing the hair removal function.
