<p>The stick (10) is assembled of several segments (12, 13, 14, 15, 16) which can be joined with sleeves (21, 22, 23) positioned between them. The second lowest segment (16) is telescopically joined to the lowest segment (15). A rope (19), locked under a helical spring (37) inside the upper segment (12) is guided through all segments (13, 14, 15, 16) and locked with the opposite end inside the second lowest (16) of the segments. For assembly the sleeves (21, 22, 23) are arrested and the second lowest section (16) pulled into position resulting in a tensioning of the rope (19).</p> |
