A treadmill includes a horizontal frame, an upright frame disposed upwardly on a front portion of the horizontal frame, and a horizontal deck laid over the horizontal frame and having a front portion connected pivotally to the front portion of the horizontal frame so that the deck can be turned upwardly on the horizontal frame to a folded position, where the deck abuts against the upright frame. A locking device includes a front tube having a front end connected pivotally to the rear portion of the horizontal frame, and a front positioning hole formed in a rear end thereof. A rear tube has a rear end that is connected pivotally to the rear portion of the deck, a front end that is connected telescopically to the rear end of the front tube so that the deck can be folded on the upright frame, and a rear positioning hole formed therein such that rotation of the deck to the folded position causes the rear tube to move away from the front tube. A spring-biased lock pin is disposed on one of the front and rear tubes, and is biased to extend through the front and rear positioning holes in the front and rear tubes when the deck is rotated to the folded position.

1. A treadmill comprising:a base member including a horizontal frame with front and rear portions, and an upright frame disposed on and extending upwardly from said front portion of said horizontal frame, and having a handle member attached to an upper thereof; an elongated horizontal deck laid over said horizontal frame of said base member, and having a front portion pivotally connected to said front portion of said horizontal frame so that said deck can be turned upwardly on said base member to a folded position, and a rear portion that abuts against said upright frame when said deck is rotated to said folded position; and a locking device including a front tube having a front end that is connected pivotally to said rear portion of said horizontal frame of said base member, a rear end, and a front positioning hole formed therein, a rear tube having a rear end that is connected pivotally to said rear portion of said deck, a front end that is connected telescopically to said rear end of said front tube so that said deck can be folded on said upright frame of said base member, and a rear positioning hole formed therein, rotation of said deck to said folded position causing said rear tube to move away from said front tube, thereby increasing total length of said front and rear tubes, and a spring-biased lock pin disposed on one of said front and rear tubes and biased to extend through said front and rear positioning holes in said front and rear tubes when said deck is rotated to said folded position, thereby locking said deck at said folded position.
