Document Type and Number:
WIPO Patent Application WO/2020/235924
Kind Code:
A1
Abstract:
Disclosed is a crank system of a pedal-type simulation device. The present invention is characterized by comprising: a plurality of crankshafts installed side-by-side in a body; a pair of left and right engagement links which eccentrically hinge-connect left end portions and right end portions at the same time in the plurality of crankshafts, and which configure the left and right hinge portions to be symmetrical with respect to the centers of the crankshafts; and a pair of left and right operation pedals which are mounted to the respective engagement links to rotate the crankshafts. According to the present invention, the plurality of crankshafts are connected by links and engaged with each other, and thus the operation pedals mounted to crank arms can constantly maintain a horizontal position so that a user can put both feet thereon. Also, the risk of the pedals tilting or the feet of the user falling off due to an imbalance in the force applied to both feet can be effectively prevented, thus enabling accurate and stable operation.
