Abstract
Adjustable hurdle apparatus (10, 110) positionable on a running track as a barrier to runners in track events including a supporting framework (11, 111), a horizontal crossbar (45, 75, 120) to be cleared by runners positioned proximate an extremity of the supporting framework, a base (12, 112) attached to the supporting framework proximate the extremity of said framework opposite the horizontal crossbar for normally maintaining the supporting framework in a substantially vertical orientation relative to the track, and means (25, 26; 75, 76; 130) for infinitely adjustably vertically positioning the horizontal crossbar from competition heights to heights which are substantially below the lowest competition height.
