Patent ID: 7354406

Claim:
An exercising apparatus comprising: at least one motion unit, each motion unit including a moving unit installed at one end thereof with a hinge unit rotatably fixed; and an up-and-down reciprocating unit connected with the other end of the moving unit, the up-and-down reciprocating units reciprocating upward and downward and making the moving units rotate in an angular interval; and wherein a driving unit is connected with the up-and-down reciprocating units of the at least one motion unit, the driving unit driving the up-and-down reciprocating units to reciprocate upward and downward; wherein a pair of the motion units are arranged in a longitudinal direction thereof, and the hinge units of the pair of the motion units face each other; wherein each up-and-down reciprocating unit comprises: a driving unit connecting shaft to which rotating force is transmitted from the driving unit; an eccentric rotary shaft eccentrically connected with the driving unit connecting shaft; and at least one link unit, one end of the link unit hingedly connected with the other end of the moving unit, and the other end of the link unit rotatably connected with the eccentric rotary shaft; and wherein the driving unit is a motor having a pair of driving shafts respectively at ends of the motor, the respective driving shafts are connected with the driving unit connecting shafts of the respective motion units by a rotation transmitting unit; and wherein further, the rotation transmitting unit comprises pulleys respectively connected with the driving shaft and the concentric shaft and a belt connecting the pulleys.
