Abstract
A reversibly slide-swingable balance-training apparatus includes a base unit, a transmission unit mounted in the base unit and providing a movement-constraining eccentric shaft and a power-maintaining rotary member for rotating the movement-constraining eccentric shaft continuously, one or a pair of linkages each having a first link pivotally connected to the movement-constraining eccentric shaft of the transmission unit, a second link pivotally coupled between the first link and the base unit and a third link pivotally connected to the second link, and a platform pivotally connected to the first link and third link of each linkage. Subject to the oscillation motion of the links of the linkage counteracting the postures of the user and the functioning of the movement-constraining eccentric shaft and the continuation of the energy of the power-maintaining rotary member, the platform is reversibly slide-swinging for best balance training.
