Abstract:
1. A shock absorption device for a running apparatus, the device comprising: a support frame, being provided at a bottom side of a lifted base of a running apparatus that is resting on a support surface; a cushion seat, being pivotably attached to a middle portion of the support frame via a pivotal shaft; a support base having two upwardly protruding cylindrical openings, each with a first diameter, being provided at a distance below the cushion seat; at least one slide rod, having an upper end and a lower end, being disposed in the cylindrical openings between and connecting with the support base and the cushion seat, and the slide rod being surrounded with a first elastic member respectively, the slide rod includes a member fixedly attached to said lower end wherein the member has a diameter that is larger than said cylindrical openings; and and a second elastic member having a dome shape, being provided at a bottom side of the support base, has a receiving space available for the slide rod moving in and out thereof; whereby when the lifted base of the running apparatus is angularly elevated or lowered relative to the support surface, the pivotal shaft allows for the shock absorption device to maintain a substantially upright position such that an impact force on the lifted base can be mitigated more sensitively by the first and second elastic members.
