| 摘要 |
A slalom post (1) is described comprising at least one eccentrically pivoted disc-like anchor element (5, 8) normally positioned substantially within the cross-sectional area of the lower end of the post. By simply twisting the slalom post (1) around its vertical longitudinal axis (4), the anchoring element (5, 8) is brought from its normal ineffective position into its effective anchoring position by rotation around a vertical axis offset and parallel to the vertical longitudinal axis of the slalom post. If desired, a roughened peripheral edge of the disc may be provided for engagement with the snow or ice into which the lower end of the post is placed so that the rotation of the post will rotate the disc-like anchoring element relative thereto to move it into its effective anchoring position. A stop or guide means may be attached to the post or the extension thereof containing the anchoring element in order to limit the orthogonal projection of the anchoring means in both its ineffective and most effective positions. Furthermore, sleeves may be provided over the lower end of the post for indicating whether the post is to be rotated clockwise or counterclockwise and for lining the hole into which the end of the slalom post is to be inserted.
