Abstract
A retractible stop mechanism is disclosed, for a conveyor system or the like, in which a stop member is moved up and down between a retracted position and a position in which it blocks an article, and a pivoted tension link is connected between the supporting structure and the stop member to provide the reaction force against the force exerted by the blocked article on the stop member, thereby removing frictional resistance to retraction of the stop member. Also, the location of the pivot of the tension link is such that a force component is developed which assists the retracting force acting on the stop member.
