Document Type and Number:
WIPO Patent Application WO/2024/009742
Kind Code:
A1
Abstract:
Provided are a load transmission mechanism unit for a training machine that enables build-up of more flexible and elastic muscles, and a training machine employing the same. This load transmission mechanism unit comprises: a main driving shaft portion to an end portion of which an input portion is connected and that rotates together with the input potion; an intermediate shaft portion that rotates in coordination with rotation of the main driving shaft portion; a first rotation transmission portion; a second rotation transmission portion; an inner housing; an outer housing; a sliding shaft portion that is arranged in the outer housing and biased in a linear direction by an external force; rotation having a first central axis orthogonal to the axial direction of the sliding shaft portion; and a coupling joint portion. The coupling joint portion converts rotation and axial movement of a crank shaft portion into a displacement of the sliding shaft portion in an up-and-down direction. When a user moves the main driving shaft portion horizontally through a gripping portion or a footrest portion, an external force applied to the sliding shaft portion is transmitted to the grip portion or the footrest portion through the main driving shaft portion.
