Abstract: A hurdle includes two base parts, each base part having a hollow space; a counterweight; a gear transmission arranged in each base part to displace the counterweight; tubular elements that include first second tubes displaceable telescopically relative to one another, each of the first tubes being fixed to one of the base parts; locking elements that lock the first and second tubes relative to one another; a bar connecting upper ends of the second tubes; a force-transmitting unit that extends from the hollow space in each base part and is connected to an associated second tube; and guides arranged in each base part, where the gear transmission engages both with the force-transmitting unit and with a driver for the counterweight, where the force-transmitting unit is received in the guides, and where the gear transmission is adapted to cooperate with openings provided in the force transmitting unit.

Abstract: A hurdle for hurdle racing with two hollow base parts/feet arranged at a distance from one another and designed to rest on a supporting surface, wherein a counterweight is displaceably arranged in each base part, tubular elements extending vertically in relation to the supporting surface are fixed to one end of each base part, with each tubular element consisting of two tubes displaceable telescopically relative to one another, elements for locking the telescopic tubes relative to one another and a bar connects the upper ends of the tubes situated furthest away from the associated base part. A strip-type force-transmitting element extends from the hollow space in each base part to the associated tubular element, and is connected to the tube supporting the bar, a gear transmission device arranged in each base part engages both with the strip-type force-transmitting element and with a driver element for the counterweight.
