The present invention relates to a
stirrup safety structure, which is integrally formed and mainly composed of pedals and
inverted U-shaped suspension locking racks. Wherein, appropriate number and shape of troughs are engraved on the pedal to limit the sticking on of mud. Moreover, a stopper ring is respectively set at the prefixed position of the lower section
lying in between both ends of the suspension rack; appropriate numbers of movable pulleys are set at the lower rod between said stopper ring and pedal; said movable pulleys have the effect of free rotating. Hence, when a horse-rider falls down from the horseback, said movable
pulley can enable the rider to free slip and withdraw his feet from
stirrup smoothly, by means of said movable
pulley's
rubbing and revolving with the rider's feet and the
momentum caused by the horse's running, to avoid his feet being hooked by the
stirrup. Therefore the present invention can solve the problem of a horse-rider's being dragged along by the horse and get hurt when he falls down from the horseback and, therefore, becomes a simple and effective safety protection device.
