  • Patent number: 4078569
    Abstract: A device for plucking out hairs by utilizing heat generated by the application of high frequency waves but which prevents the transfer of the heat to the skin. The device comprises a main body substantially in the form of a letter U including a pair of elongated legs and a curved portion which has a certain degree of flexibility. One of such elongated legs is connected to a high frequency wave generator. A pair of hair clamping members formed as hair clamping tongs is connected to the other elongated leg. A link mechanism is arranged in the two legs and coupled to a set lever for moving the tips of the hair clamping members from a position in which they are in engagement with each other, to a position in which they are out of engagement with each other by utilizing the flexibility of the curved portion of the main body so that the hair clamping members can nip, transmit heat to and pluck out a hair in one operation.
