    Abstract: A stick that is excellent in shock absorption and is also excellent in stability is provided. A stick body is provided with a telescopic extension pipe formed by fitting an outer tube and an inner tube together in a nesting manner. Inside the extension pipe, a velocity-dependent damper that damps the relative sliding movement between the outer tube and the inner tube, and a compression coil spring that concentrically fits onto the damper and urges the extension pipe so as to be extended are connected in parallel. According to such a stick, the shock transmitted to the hand can be mitigated as the compression coil spring contracts upon landing. Also, since the damper suppresses unwanted vibration of the extension pipe, the length of the stick quickly becomes stable after landing, allowing the user to keep stable balance with the stick.

    Abstract: An ambulatory aid is revealed. The ambulatory aid includes a hollow main rod and a hollow support pole connected with each other, and a cushion unit therebetween. The main rod, the hollow support and the cushion unit all have insertion holes, aligned with each other. By insertion pins inserted into the insertion holes, the main rod, the hollow support and the cushion unit are assembled with each other. The structure of the assembly of the main rod, the hollow support and the cushion unit is more firm and tighter. When the ambulatory aid is pressed by a larger pressure, the assembly will not come loose and move around and the unstable walking stick makes the users fall down due to a loss of support.
