Patent ID: 8801576

Claim:
A vibratory exercise apparatus having an electricity generating function, comprising: upper and lower plates formed to be spaced apart from each other at a predetermined interval; a vibrator configured to vertically vibrate the upper plate up and down including an operating unit fixed to a center of the upper plate, and a bobbin unit installed on the lower plate at a position corresponding to the operating unit and having a coil wound on the bobbin unit and configured to generate a magnetic field by receiving a drive signal; and a vibration absorbing unit installed between the upper plate and the lower plate and configured to absorb an impact generated when the upper plate is lowered while the upper plate is vertically vibrated up and down, wherein the operating unit of the vibrator includes an operating unit cover formed as a circular disk made of a magnetic material and having a plurality of fastening holes for fastening to the upper plate, an outer ring fastened to an edge of the cover and formed in an annular shape having a predetermined height, an inner ring installed to be spaced apart from the outer ring at a predetermined interval while forming a concentric circle inside the outer ring, a center post installed to be spaced apart from the inner ring at a predetermined interval while forming another concentric circle inside the inner ring, a vibration generating magnet made of a ferromagnetic material, attached between one side of the inner ring and the operating unit cover, and configured to magnetize the inner ring and the outer ring, and an electricity generating magnet installed on a protruding end of the center post, and wherein the bobbin unit of the vibrator includes an inner bobbin having a center hole which the electricity generating magnet of the center post is drawn into and out, and an electricity generating coil wound on an outer circumferential surface thereof, an outer bobbin installed to be spaced apart from the inner bobbin at an interval that allows the inner ring of the operating unit to be drawn into and out, while forming a concentric circle outside of the inner bobbin, and having a vibration generating coil wound on an outer circumferential surface thereof, and a bobbin cover coupled to the inner bobbin and the outer bobbin, and having a plurality of fastening holes for fastening to the lower plate.
