Abstract:
1. Vibrating plate apparatus, comprising a vibrating plate adapted to support a user desiring muscular toning, a vibration motor member connected to the vibrating plate and adapted to vibrate said plate at a pre-determined frequency, a plurality of air cushions provided under said vibrating plate and adapted to dampen vibrations, and an air tank in communication with each of the air cushions and adapted to maintain an air pressure of said air cushions at a pre-determined value, wherein said tank is adapted to establish the air pressure in at least one of the said air cushions at a pre-determined value independently from a weight of the user; wherein said vibration motor member includes two motors rotating in opposite directions, each of the two motors including a set of flyweights driven by a rotation axis of the motors and having a center of gravity that is offset relative to the axis, wherein both sets of flyweights have the same mass and are symmetrical relative to each other and include at least one movable flyweight that can assume at least one position for varying a vibration amplitude of said vibrating plate, wherein said set of flyweights comprises at least one flyweight fixed to said motor member and wherein said movable flyweight is in an intermediate position at 90° in reference to a position of said fixed flyweight in order to cause a slope change of the amplitude vibration of said vibrating plate so as to obtain a double wave.
