Abstract

This invention is relating to a buffer structure to be installed in between the framework of jogging machine and the floor surface. The jogging machine is comprised of one framework, one front floor-rod, one hand holder and one rear floor-rod, etc. components. Amid the components, framework has a jogging board installed on its end surface. And one jogging track is enclosed to surface of this jogging board on its up and down end. Thus this installation can enable user to stand on jogging track and start jogging exercise. The key point here is that there is a pulling board transversely pivoted to the top end of two bent chips incorporated to rear floor-rod. And one side of the pulling board has a pivot lug to pivot an adjustment screw rod. Then let this screw rod pass through the holes drilled on the front & rear partition boards and place a buffer pad in between front and rear partition boards. Finally use one screw rod socket and one knob to bolt screw rod together. After the buffer pad is installed, it can effectively absorb the gravity that framework is carrying. It can also lessen the reaction force fed back by floor surface, and further to weaken the vibration phenomena created when framework is stressed.

Claims

1. A buffer structure for a jogging machine having a framework movably supporting a jogging track, the framework having side frames, first and second partition boards extending transversely between the side frames, and a floor support assembly supporting the framework on a floor surface, the floor support assembly pivotally connected to the framework so as to pivot about a transverse pivot axis, the buffer structure comprising:

a) an adjustment screw rod extending through the first and second transverse partition boards, the adjustment screw rod having a threaded first end and a second end;

b) a tubular buffer pad mounted on the adjustment screw rod, the buffer pad located between the first and second transverse partition boards;

c) a pulling board attached to the floor support assembly at a location spaced from the transverse pivot axis;

d) a connection device connecting the second end of the adjustment screw rod to the pulling board; and

,

e) an adjusting knob mounted on the threaded end of the adjustment screw rod.

2. The buffer structure of claim 1 wherein the connection device comprises a clevis connection.

3. The buffer structure of claim 1 further comprising a screw rod socket interposed between the adjusting knob and an adjacent partition board.
