Elliptic motion trace pedal system

Abstract

The invention discloses a pedal system with elliptic moving track, it mainly includes big gear, small gear, control plate, and adjusting equipment, the control plate is immovable or forced rotating to adjust equipment limitation, the big gear uses the axes of control plate as its axes and can rotate freely, the peripheral of big gear sets a reversely rotating axe, there are small gear and extending pole at two ends of eversal axe, the small gear connects with control plate through chains or gear plate, the end of extending pole has pedals.

Description

technical field [0001] The invention relates to a pedal system, in particular to a pedal system with an elliptical motion track. Background technique [0002] Generally used as a sports or rehabilitation appliance for simulating the foot movement trajectory when the human body walks, such as U.S. Patent No. 5,242,343, No. 5,383,829, No. 5,518,473, No. 5,562,574, No. 5,577,985, No. In this case, according to the structure of these appliances, when the operator steps on the pedal with his foot, the motion trajectory of the pedal is usually in a shape similar to an ellipse, so as to simulate the foot motion trajectory when the human body walks. [0003] According to the survey report, when the human body walks, the trajectory of its feet is generally in the shape of a true ellipse. However, the structure of the above-mentioned reference case shows that the trajectory of the pedals can only complete a shape similar to an ellipse, that is, It can't really reach the foot movement...

[0003] According to the survey report, when the human body walks, the trajectory of its feet is generally in the shape of a true ellipse. However, the structure of the above-mentioned reference case shows that the trajectory of the pedals can only complete a shape similar to an ellipse, that is, It can't really achieve the foot movement trajectory when simulating human walking
