Abstract
A system includes a vibration unit that provides independent adjustability of vibration characteristics such as frequency and amplitude and may provide a first motor that rotates an eccentric and can adjust vibration frequency and a second motor that that may move the eccentric within the vibration unit in a manner that adjusts amplitude of the vibration.
Claims8
An apparatus for generating musculoskeletal vibration comprising:
- a shaft with a diagonal segment positioned for rotation about an axis angularly intersecting the diagonal segment of the shaft and having an eccentric portion arranged for rotation along an eccentric path about the axis so as to produce vibrations;
- a motor for rotating the shaft;
- a positioner that engages the eccentric portion at opposite sides of the eccentric portion for adjustably moving the eccentric portion to different locations within the apparatus corresponding to different positions with respect to the diagonal segment of the shaft during use;
- and
- a support that can engage a foot of a user of the apparatus and that is adapted to be reciprocally driven by the eccentric portion to receive vibrations having an amplitude that corresponds to a position of the positioner and the eccentric portion with respect to the diagonal segment of the shaft within the apparatus and so as to adjustably conduct the vibrations to the foot during use.
