Shock absorbing mechanism of displacement for stick, leg, etc.

摘要

This invention intends to provide a shock absorbing mechanism for displacement for a stick, an artificial leg etc such as a walking stick, a crutch, a stick for sports, an artificial leg, a walking tool for a patient, a chair, or a protecting bed, in which elastic materials having several different moduli of elasticity are built in a small space of a compression coil spring, and accomplish an elastic sticky force like a human muscle which is light and low in cost.
