Title:
LEFT AND RIGHT OSCILLATION WIDTH ADJUSTMENT AND ROTATION STRUCTURE OF STATIONARY BIKE SADDLE
Document Type and Number:
WIPO Patent Application WO/2021/206453
Kind Code:
A1
Abstract:
The present invention relates to a right and left oscillation width adjustment and rotation structure of a stationary bike saddle, which enables a user to directly perform adjustment to correspond to the range of motion of the hip joint while inducing the buffering action of the left and right oscillations of the saddle and the dispersed load when the user sits on the saddle of the stationary bike and pedals thereon, so as to secure stability for the motion of the pelvis and spine during pedaling and enables core muscle training at the same time as lower body exercise during pedaling, the structure consisting of: a buffering part (100) which is disposed on the bottom surface of a saddle member (8) to relieve the load and left and right oscillations dispersed by the user's pedaling operation; a left and right moving part (200) which is coupled to the buffering part to perform a left and right sliding motion; a forward and backward moving part (300) which is coupled to the left and right moving part (200) to perform a forward and backward sliding motion; and an eccentric rotating part (400), in which the left and right moving part (200) and the forward and backward moving part (300) are coupled and which is rotated eccentrically to simultaneously control the sliding motion of each moving part. The eccentric rotation radius of the eccentric rotation part (400) can be expanded or reduced according to the user's selection, and the left and right sliding and forward and backward sliding motions are controlled by the adjusted rotation radius.
