2. Description of the state of the technique

Generally is a walking stick of many people for mountain hiking and for athletic activities and used by patients as a walker. Of the Walking stick has a rod and a handle, which at one end area of the rod is provided. The rod is usually replaced by several Connecting pipes formed, which are connected so that they convenient storage and use in a longitudinal direction can be folded.

An example of the walking stick is in the 1 and 2 shown.

As the 1 and 2 show, the walking stick has a handle 2 which may have different shapes according to different purposes, a rod 4 which forms a body, and a pointed head area 6 for contact with the ground.

The rod 4 is through a plurality of connecting pipes 10 . 20 and 30 formed, which are connected together in a collapsible longitudinal direction, and detents 40 and 40a are intended for connection areas to lock the walking stick in a maximum length or to release the lock to collapse the walking stick.

In particular, in the first connecting pipe 10 the second connecting pipe 20 with smaller diameter and in the second connecting pipe 20 the third connecting pipe 30 used with smaller diameter, and the detents 40 and 40a are respectively for the connection area between the first and the second connecting pipe 10 and 20 and the connecting portion between the second and third connecting pipes 20 and 30 intended. Depending on your needs, hiking poles of various lengths can be made by adding the number of connecting pipes 10 . 20 . 30 is increased or decreased.

In the connecting portions between the upper connecting pipe and the lower connecting pipe, that is, between the lower end of the first connecting pipe 10 and the upper end of the second connecting pipe 20 and between the lower end of the second connecting pipe 20 and the upper end of the third connecting pipe 30 , are anti-vibration elements 51 . 52 . 61 and 62 intended to prevent vibration during use of the walking stick.
