Foldable treadmill having lifting mechanism

Abstract

A foldable treadmill having lifting mechanism is provided. A base is connected to a running platform through two swing arms. The running platform controlled by the actuation device and the link of a lifting mechanism is upwardly swung on the base. When the lifting mechanism is activated, the link is moved on a support surface. When the actuation device is stretched out, the running platform is lifted and backwardly shifted relative to the stand post. When the actuation device is contracted, the running platform is descended and forwardly shifted relative to the the stand post.

What is claimed is: 
     
         1 . A foldable treadmill having lifting mechanism characterized in that:
 a base, two sides of the base having a member respectively, one end of each member having a stand post that is upwardly disposed;   a running platform having a pivot portion respectively at the front end;   a lifting mechanism disposed between the base and the running platform and comprising a telescopic actuation device and a link, one end of the link connected to the pivot portion, one end of the actuation device connected to the running platform while another end of the actuation device connected to the link, wherein when the lifting mechanism is activated, another end of the link moves on a support surface, and when the actuation device is stretched, the running platform is lifted and backwardly shifted relative to the stand post, and when the actuation device is contracted, the running platform is descended and forwardly shifted relative to the stand post;   two swing arms, one end of the two swing arms connected to the pivot portion of the running platform while another end of the two swing arms pivotally connected to the base and located between front and rear ends of the member.   
     
     
         2 . The foldable treadmill having lifting mechanism as recited in  claim 1 , characterized in that the support surface is a rail, and the rail is parallel the member. 
     
     
         3 . The foldable treadmill having lifting mechanism as recited in  claim 1 , characterized in that a support component is disposed between the running platform and the base to support the running platform that is folded. 
     
     
         4 . The foldable treadmill having lifting mechanism as recited in  claim 1 , characterized in that the link comprises two support rods, and a horizontal rod is connected between the two support rods, one end of the actuation device is pivotally connected to the horizontal rod, one end of the two support rods is pivotally connected to the pivot portion of the running platform, and another end of each support rod is moved on the support surface. 
     
     
         5 . The foldable treadmill having lifting mechanism as recited in  claim 1 , characterized in that the actuation device comprises a lift motor, a screw and a sleeve, one end of the sleeve is pivotally connected to the link.
