Hair removal apparatus
An apparatus ( 10 ) for removing hair employs two overlapping thread portions ( 14 ) and ( 16 ) wherein one thread portion is helically wound or coiled around the other to form at least one hair trap ( 18 ) to grasp and pull strands of hair. A motorized oscillation arm ( 32 ) alternately tightens and loosens each side of one thread portion to manipulate the hair trap. The thread is held in tension in a readily removable and replaceable yoke ( 12 ) to facilitate disposal of the used thread and replacement with unused thread. A housing ( 20 ) contains a battery-operated motor ( 24 ) to move the oscillation arm which has hooks ( 36 ) to engage the thread.
1 . Hair removal apparatus comprising first and second threads overlapping in a coiled engagement to define at least one hair trap, said apparatus including a yoke for maintaining said first and second threads resiliently under tension, said apparatus also including a motorized oscillation arm to alternatively tighten and loosen said second string to manipulate said at least one hair trap in a manner to capture and extract hair.
2 . Hair removal apparatus as in claim 1 wherein said first and second threads are defined by the single thread which is formed in a loop and coiled to define said hair trap, said yoke including a flexible U-shaped, resilient member, ends of a first side of said loop being anchored at end points of said resilient member, ends of a second side of said loop being anchored at said flexible U-shaped member at positions spaced apart from said end points.
3 . Hair removal apparatus as in claim 1 , said yoke comprising a flexible U-shaped member having first and second end anchor points, said first thread being anchored between said first and second end anchor points under tension, said second thread being anchored to said U-shaped member at first and second positions on said U-shaped member spaced apart from said first and second end anchor points respectively.
4 . Hair removal apparatus as in claim 1 further comprising a housing having a motor and a source of power for said motor, said motor being coupled to said oscillation arm for angular oscillatory motion of said arm.
5 . Hair removal apparatus as in claim 4 wherein said motor is coupled to said oscillation arm by a rotating disc and a connecting arm, said connecting arm being connected to said disc and to said oscillation arm.
6 . Hair removal apparatus recited in claim 1 wherein said hair trap comprises a portion of said first thread around which a portion of said second thread is helically wound.
7 . Hair removal apparatus recited in claim 6 wherein said hair trap manipulation causes the helically wound portion of said second thread to translate along said first thread.
8 . Hair removal apparatus recited in claim 1 wherein said first and second threads are two distinct portions of one continuous thread.
