Abstract
The present invention relates to an elevatingly folding unit of an electric exercise treadmill having a main frame, a deck frame, a belt-driving assembly and an elevatingly folding unit. The deck frame is interposed between two foot seats, including a deck and a continuous belt. And the belt-driving assembly is disposed at one end of the deck frame to drive the continuous belt for a cyclical rotation. In addition, the elevatingly folding unit is used for the deck frame to perform an elevating or a folding action. This folding unit makes use of a servomotor to drive the transmission spindle through a gearbox such that a slide shaft is movable forward and backward. The slide shaft is pivoted with two elevating rods while the other end thereof is pivotally mounted on a fixing shaft of the deck frame. When the slide shaft moves forward and backward, a relatively elevating action will be created at one end of the deck frame. Moreover, when the slide shaft moves, the folding support pivoted at one end of the foot seat and a movable support are pivotally joined with the deck frame such that a relatively folding action of the deck frame is created.
