Abstract
The present invention relates to an elevating apparatus of an exercise treadmill. The elevating apparatus utilizes a servomotor to drive a transmission spindle into rotation by a gearbox, thereby driving a slide shaft to move to and fro between two base bars of the main frame. At least two lift shafts are pivotably connected to one end of the slide shafts while the other end thereof is pivotably connected to folding bars. Either folding bar is L-shaped and includes a first, a second and a third pivoting members. Moreover, the first pivoting member is pivotally mounted on the deck, the second pivoting member is pivotally mounted on the main frame and the third pivoting member is selectively pivotally attached to the deck by a latch. Accordingly, when the third pivoting member is separated from the deck, the elevating apparatus will perform an elevating action to be located at an inclined position. And when the third pivoting member is positioned in the pivoting hole of the deck, the elevating apparatus will perform a folding action to be located at a substantially upright position.
