ABSTRACT:
A stick, such as a trekking stick, ski pole or walking stick, is provided with a shock absorber between a first and a second tubular section of a stick shaft that is equipped with a handle and a stick tip. According to the invention, the shock absorber comprises a guide sleeve, which is held in a rotationally fixed manner in a tubular section and In which a damping rod that is held in an axially fixed manner on the other tubular section Is guided and a compression spring device, operating between the guide sleeve and the damping rod. The aim of the invention is to obtain softer shock absorbing characteristics and resilience characteristics that are less abrupt with minimal kickback. This is achieved by the provision of an elastomer spring in the compression spring device, said spring being located in series with a helical compression spring.
