Double-purpose body building machine for stepping motion and elliptic motion

Abstract

The invention relates to a double-purpose body building machine for stepping motion and elliptic motion, which comprises a base, a stander, a rear shaft, left and right oscillating support poles, a drive axle and a damping mechanism. Lower ends of the left and the right oscillating support poles are respectively pivoted with left and right pedal levers through a pivot A, and outer sides of rear parts of the left and right pedal levers are respectively pivoted with left and right vertical connecting rods through a pivot B; upper ends of the left and right vertical connecting rods are respectively pivoted with left and right bent rods through a pivot C, and front ends of the left and right bent rods are respectively pivoted with left and right front connecting rods through a pivot D; upper ends of the left and right front connecting rods are respectively pivoted with left and right cranks through a pivot E, and the left and right cranks are respectively arranged on two sides of the drive axle; and middle parts of the left and right bent rods are respectively pivoted on left and right pivot seats of the base through a pivot F, and the upper part of the stander is also provided with left and right fixed handles. The double-purpose body building machine has the advantages of simple structure, low cost, harmonious action, safety, reliability, and capacity of providing the stepping motion or the elliptic motion for a user; a damping flywheel is replaced by a generator to supply power to an instrument; and the double-purpose body building machine can be widely applied to various body building places.

Description

technical field [0001] The invention belongs to the technical field of fitness equipment, and more specifically relates to the improvement and innovation of stepping and elliptical dual-purpose fitness machines. Background technique [0002] When the human body walks or runs, the trajectory of the foot is basically an ellipse. The elliptical machine is welcomed by bodybuilders because it imitates the walking action of the human body and conforms to the principles of human physiology and ergonomics. But the traditional elliptical machine can only complete the elliptical body-building exercise, can not imitate the stepping exercise, and has a single function. Taiwan's Zhuang Jincheng and Zhuang Longfei's Chinese patent application titled "Elliptical Machine", publication number CN101347667A, and application number 200710136419.X discloses an elliptical machine. But its "a pivot (12) is located at the front (13) of the support (11)", and another "a pivot (21) is located at th...

AI Technical Summary

Problems solved by technology

Therefore, it is both inconvenient and very dangerous to hold for stepping exercise

[0004] Also, the flywheel on this elliptical trainer does nothing but apply resistance

Moreover, the elliptical machine is not equipped with electronic instruments, so it cannot provide corresponding exercise data and parameters
