Abstract (en)
There is disclosed a rotary type adjustable cushioning mechanism of a treadmill (10), comprising a cushioning unit (20) being interposed the base frame (11) and the running board such that an expected and proper cushioning effect is created after the running board is subject to a force. The cushioning unit (20) consists of two regulating mechanisms (22) and a resilient element (30). Each of the regulating mechanisms includes a scale displaying disc, an adjustment knob, a transmission gear set, a position-adjusting threaded bolt, an elastic cushioning element, a coupled compression lever, and a coupled bracket pivotably attached to the running board. The resilient element (30) is pivotably connected between both of the coupled brackets. When the adjustment knob is turned, the elastic cushioning element (20) can move up and down on the position-adjusting threaded bolt, thereby changing the compression force between the elastic cushioning element and the coupled compression lever. As a result, the cushioning force acting on the running board can be effectively adjusted.
