Abstract

A waist twist machine having a base frame, a rear support, and a front upright rod with a handle at the top thereof. A crossbar is positioned near the center of the base frame. A rotating rod is pivotally disposed at the top of the crossbar. A rotating plate assembly is pivotally connected to the rotating rod. The rotating plate assembly includes a front rotating arm, a rear rotating arm, and two foot plates that are pivotally connected to one another. The bottom of the front and the rear end of the foot plates is pivotally attached to the front and rear rotating arms. The front and rear rotating arms each include a pivoting portion at the center thereof. The pivoting portions are pivotally coupled to both ends of the rotating rod. As a result, the front and rear rotating arms create a rotational deformation due to the action of the pivoting points when the foot plates are subject to force and are rotated. In this way, both of the foot plates create more rotational angles.

Claims

1. A rotating plate structure of a waist twist machine having:

a base frame,

a rear support,

a front upright rod with a handle at the top thereof,

a crossbar positioned at the center of the base frame,

a rotating rod wherein the rotating rod is pivotally connected at a midpoint of the rotating rod to a midpoint of the top of the crossbar, and

a rotating plate assembly being pivotally connected to the rotating rod, wherein the rotating plate assembly includes

a front rotating arm,

a rear rotating arm, and

two foot plates that are pivotally connected to one another, and wherein the bottom of the front and the rear end of each foot plate is pivotally attached to the front and the rear rotating arms, and wherein the front and rear rotating arms each include a pivoting portion at the center thereof, and wherein the pivoting portions are pivotally coupled to both ends of the rotating rod;

therefore, the front and rear rotating arms create a rotational deformation due to the action of the pivoting points when the foot plates are subject to force and are rotated.
