Abstract
Intermediate regions are provided between straight and circular-arc slide sections having a curved sliding surface in cross-section, the intermediate regions being clothoid-shaped in top view. In an intermediate region, which starts with a quarter-elliptic cross-section of the sliding surface at the outer side of the curve corresponding to the cross-sectional shape of the straight slide section, the ratio between the major and the minor axes of the ellipse continuously changes towards the other end so that individual trajectories depending on the velocity of the vehicle form in top view a sheaf of clothoids having the same initial point. The individual structural elements of the slide are flanged at their ends, one flange, each, of two structural elements being adjustable in various directions and supported by a strut.
Claims7
A sporting or recreational slide, particularly for use with unsteered vehicles, said slide comprising:
- a plurality of joined sections which form a sliding surface and which form regions which are, when viewed from above, straight regions, circular-arc regions and clothoid-shaped intermediate regions between and joining adjacent straight and circular-arc regions;
- said intermediate region having a first end at said straight region and a second end at said circular-arc region;
- and
- said sliding surface at the outer curved side of said intermediate region having a cross-sectional shape which continuously changes between said first and second ends, said cross-sectional shape at said first end comprising a quarter of an ellipse corresponding to the cross-sectional shape of said sliding surface at said straight region, and the ratio between the major axis and the minor axis of the ellipse continuously decreasing toward said second end.
