ABSTRACT:
A departure gate for sporting runs includes two riser members forming an outlet, each riser member bearing a device comprising a bar arranged to be angularly movable, the bar extending at least halfway over the width of the outlet. Each device includes an electrical contractor controlled by the bar and operated thereby as soon as the bar has traversed a predetermined angle (.alpha.). The contactors are coupled in a manner such that an electrical output signal is produced only when at least one of the bars has traversed the angle .alpha.. The gate minimized or eliminates the influence that the starting position of the contestant may have on his result.
