<p>This invention relates to a buffer structure to be installed in between the framework (21) of jogging machine and the floor surface. The jogging machine comprises one framework (21), one front floor-rod (22), one hand holder (23) and one rear floor-rod (24). The framework (21) comprises a jogging board (26) installed on its end surface. A jogging track (27) is enclosed to surface of this jogging board (26) on its up and down end. Thus this installation can enable the user to stand on the jogging track and start jogging exercise. The key point is that there is a pulling board (30) transversely pivoted to the top end of two bent plates (28) incorporated to rear floor-rod (24). One side of the pulling board (30) has a pivot lug (31) to pivot an adjustment screw rod (32). The screw (32) rod is passed through the holes drilled on the front and rear partition boards (211,212) and a buffer pad in placed in between the front and rear partition boards (211,212). Finally one screw rod socket (34) and one knob (36) are used to bolt the 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 weaken the vibration phenomena created when framework is stressed. <IMAGE></p> |
