RUNNING TRACK

FIELD: sports equipment. SUBSTANCE: running track has continuous drive belt formed as set of V-belts and flat belts, driving and driven rollers, driving and driven rings, driven shaft, paired outer hemispherical support with antifriction and shank and inner support with horizontal opening and vertical surface, guide, inner bolt, outer bolt with internal and external threads and nut. V-belt and flat belts are mounted one behind the other and in symmetry with their longitudinal mid portion. Each neck of driving and driven rollers and rings is disposed in inner support, each neck of driven shaft is disposed in outer hemispherical support, and shank is positioned in guide. Outer bolt is in contact with vertical surface of inner support and inner bolt is in contact with shank end through internal thread of outer bolt and horizontal opening of inner support. Flat belts run around driving rings, driven shaft and antifrictions of outer hemispherical supports. Such construction allows power consumed by continuous drive belt to be reduced and width of training ground to be increased without increasing size of running track. EFFECT: increased efficiency, simplified construction and reduced power consumption. 2 dwg
