Abstract
Abstract A slalom post (1) is described at the bottom end of which an anchoring element (3) shaped as a flange (3) is provided collaborating with a protection wedge (7). The flange (3) may be moved from a non-effective position when the flange (3) is within the profile of the protection wedge (7) into an effective position when it projects beyond the profile of the slalom post. In this way, a structurally simple, easily operable and very effective anchoring of the slalom post is obtained.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
212 words
A slalom post having a bottom end, said slalom post comprising: a. at least one anchoring element connected to said slalom post in the area of said bottom end, each said anchoring element comprising a laterally projecting substantially horizontally flat flange extending perpendicular to the vertical axis of said post and torsionally stably secured to and extending outwardly beyond the cross-sectional profile of said post; and b. at least one protection wedge rotatably attached to said post adjacent said flange for rotation about the axis of said post, holding means preventing said protection wedge from moving along said axis of said post, the direction of the longest dimension of said wedge being parallel to the axis of said post with the protection wedge having a cross-sectional profile perpendicular to said post axis, said profile being approximately the same shape and size as said projecting flange, the wedge and flange being aligned with the post is forced into the snow such that said wedge protects said flange from bending, and then on rotation of said post about its axis once said post has been forced into the snow the relative rotation of said flange and wedge exposes said flange so that it acts to prevent the slalom post being pulled from the snow.
Claim 2
Dependent Claim
212 words
A slalom post having a bottom end, said slalom post comprising: a. at least one anchoring element connected to said slalom post in the area of said bottom end, each said anchoring element comprising a laterally projecting substantially horizontally flat flange extending perpendicular to the vertical axis of said post and torsionally stably secured to and extending outwardly beyond the cross-sectional profile of said post; and b. at least one protection wedge rotatably attached to said post adjacent said flange for rotation about the axis of said post, holding means preventing said protection wedge from moving along said axis of said post, the direction of the longest dimension of said wedge being parallel to the axis of said post with the protection wedge having a cross-sectional profile perpendicular to said post axis, said profile being approximately the same shape and size as said projecting flange, the wedge and flange being aligned with the post is forced into the snow such that said wedge protects said flange from bending, and then on rotation of said post about its axis once said post has been forced into the snow the relative rotation of said flange and wedge exposes said flange so that it acts to prevent the slalom post being pulled from the snow.
Claim 3
Dependent Claim
47 words
The Slalom post according to claim 1 wherein said protection wedge is arranged directly above said flange, the greatest cross sectional profile of said protection wedge facing said flange and the other end of said protection wedge being flattened and gradually angled inward towards said slalom post.
Claim 4
Dependent Claim
22 words
The Slalom post according to claim 1 wherein said protection wedge is secured to a rotatable bushing provided over said slalom post.
Claim 5
Dependent Claim
50 words
The Slalom post according to claim 3 wherein said bushing has an oblong hole extending peripherally about said bushing, and said holding means comprises a holding screw screwed into said slalom post and having a head thicker than the width of said oblong hole is arranged through said oblong hole.
Claim 6
Dependent Claim
21 words
The Slalom post according to claim 1 wherein said anchoring element is secured to the lower-most end of said slalom post.
Claim 7
Dependent Claim
63 words
The slalom post according to claim 1 wherein said slalom post further comprises a lower portion, an upper portion and a hinge-like joint between said lower and upper portions for permitting said upper portion to tilt relative to said lower portion, and means engaging said lower and upper portions for preventing a twisting of said lower and upper portions relative to each other.
Claim 8
Dependent Claim
26 words
The Slalom post according to claim 6 further comprising a rubber-elastic bushing positioned over and connected to the adjoining ends of said lower and upper portions.
Claim 9
Dependent Claim
17 words
The Slalom post according to claim 6 wherein said lower and upper portions have serrated joining ends.
Claim 10
Dependent Claim
19 words
The Slalom post according to claim 8 wherein said serrated joining ends are plates rendering the tilting movement possible.
Claim 11
Dependent Claim
25 words
The Slalom post according to claim 1 wherein said protection wedge is shaped as a bushing having an eccentric bore to receive said slalom post.
Claim 12
Dependent Claim
15 words
The Slalom post according to claim 10 wherein the profile of said bushing is non-circular.
Claim 13
Dependent Claim
25 words
The Slalom post according to claim 10 wherein a second flange is secured to the upper end of said bushing extending beyond the profile thereof.
