1. A slalom post having a central longitudinal axis and a cylindrical outer surface, and having at its lower end an anchoring means, said anchoring means comprising:

  • a sleeve around said post, a disc-like anchoring element below said sleeve having an area substantially equivalent to the circular cross-sectional area of the cylindrical surface of said post, a pivot for said element on an axis offset and parallel to the central vertical axis of said post, and a guide means on said sleeve engaging said anchoring element for limiting the relative oscillations of said anchoring element to the oscillations of said post about its central vertical axis, whereby oscillation of said post about its central vertical axis causes said anchoring element to move about its offset axis from an ineffective position substantially within the cross-sectional area of said post to an effective anchoring position projecting radially outwardly from the cylindrical surface of said post, and vice versa.
