US Patent 11607598 Folding treadmill and folding method

Disclosed are a folding treadmill and a folding method. A folding method of a folding treadmill includes the following steps: unlocking a pin lock assembly to enable a column assembly and a running platform to be in an unlocked free state, then unfolding or folding the column assembly to be in an unfolded state or a folded state relative to the running platform, and locking the pin lock assembly to complete the unfolding or folding of the treadmill. By means of the pin lock assembly, the column assembly can be firmly locked on the running platform no matter whether the column assembly is in the unfolded state or the folded state, thus not only achieving rapid unfolding and folding, but also ensuring the stability of the unfolded state or the folded state, and improving the safety of the folded state.
