Abstract (en)
The present invention relates to a lifting device for a treadmill. A lifting motor (41) with a locating transmission spindle (40) is pivotably connected to the front end of the base frame (20). A socket (42) is movable backward and forward by means of the rotational movement of the locating transmission spindle (40) while the other end of the socket (42) is pivotably connected to the top of an inverted-T-shaped cross bar (26) which extends beyond both sides of the base frame (20) and is connected with a pull rod (27), respectively. The other end of each of pull rods (27) is pivotably connected to the upright support (10), thereby forming a pivot point (28). Accordingly, when the lifting motor (41) is actuated to let the socket (42) rotate by means of the rotational movement of the locating transmission spindle (40), the inverted-T-shaped cross bar (26)and the pull rod (27)will move in the desired direction. Therefore, the base frame (20) will be moved upward and downward on the pivot point (28). <IMAGE>
