Abstract:
1. A liftable and foldable treadmill, comprising: a base frame comprising two opposing inner sides, and two sliding tracks respectively mounted at said two opposing inner sides, each said sliding track defining an upward opening at a front end thereof; a running platform mounted at a top side of said base frame, said running platform comprising a front side and a rear side opposite to the front side; two sliding devices respectively bilaterally mounted at the front side of said running platform; a lift frame mounted at a bottom side of said running platform, said lift frame comprising a front coupling portion and a rear coupling portion, said front coupling portion being pivotally connected said running platform; a folding frame mounted at a bottom side of said running platform, said folding frame comprising at least one front coupling portion and at least one rear coupling portion, the front coupling portion of said folding frame being pivotally connected to the rear coupling portion of said lift frame in such a manner that when the rear side of said running platform is lifted, said two sliding devices are respectively inserted into the upward openings of said sliding tracks and moved backwardly along said sliding tracks, and at the same time, the rear coupling portion of said lift frame and the front coupling portion of said folding frame are carried upwards by said running platform; and a linear brake mounted at said running platform, said linear brake comprising an axially movable output bar extending downwards to said lift frame and pivotally connected to said lift frame in such a manner that when said axially movable output bar is moved from an initial position in direction away from said running platform, said lift frame is turned upwardly about the axis extending through the rear coupling portion thereof from a substantially horizontal position to a tilted position to lift the front side of said running platform.
