Rocking roller exerciser

摘要

An exercise machine including a rocker frame movably coupled with a roller assembly via a torsion resistance mechanism is described. The rocker frame may include at least one arcuate rail to provide floor support for a rocking motion of the rocker frame. One or more pedal control structures may be pivotally coupled with the rocker frame near each distal end of the arcuate rail to drive the rocking motion. The roller assembly may be configured to make a rolling motion when the rocker frame rocks. A torque force can be generated via the torsion resistance mechanism as a result of changes in relative positions between the rocker frame rocking and the roller assembly rolling. The force driving the rocking motion can be countered by the torque force to support exercising movements of a user exerting the force.

1. An exercising device comprising:
a rocker frame having at least one arcuate rail to provide floor support for a rocking motion; at least one pedal control structure pivotally coupled with the rocker frame near each distal end of the arcuate rail, the pedal control structure to drive the rocking motion; and a roller assembly movably coupled with the rocker frame via a torsion resistance mechanism, the roller assembly confined to a rolling motion on a floor via the rocking motion of the rocker frame, wherein changes in relative positions between the rocker frame and the roller assembly via the rocking motion and the rolling motion cause a torque force in the torsion resistance mechanism, the torque force to counter a force driving the rocking motion to support exercising movements of a user exerting the force, and wherein the torsion resistance mechanism comprises a torsion bar affixed transversely with the roller assembly and the rocker frame, the torsion bar to generate the torque force when deformed by the changes in the relative position between the roller assembly and the rocker frame.
