摘要： A plurality of longitudinally extending straight and curved, slide segments, the upper ends of consecutive ones of which are overlapped by the lower ends of the preceding segment to define a continuous, sledding run having a predetermined configuration, including straight and curved portions. Each segment is of generally trough-like configuration and has a cross-sectional configuration comprising a shallow, concave central sled-supporting portion terminating in convex side rail portions. The convex side rail portions have a generally inverted U-shape cross section with depending flanges extending integrally and downwardly from the outer portion thereof. Butt straps removably fastened to the depending flanges interconnect each slide segment to an underlying support. The underlying supports consist of universally mounted and adjustable struts each having a tube-shaped rail insertable in the inverted U-shape of the slide rail portions. Only one strut on each side of a slide segment at one end thereof is necessary. A plurality of spaced apart ground supports are positioned along the run supporting the universal mounts of the struts. Cables having turnbuckles extend between each ground support and the next succeeding strut downhill thereof. A ski lift may extend between the ends of the run.
