发明名称 One way gate for animals
摘要 A one way gate primarily for pigs is located between a pair of parallel panels to be mounted in a fence line and includes two gate portions each defined by a transverse rail across the passage between the panels at a height above the passage and a plurality of fingers hanging from the rail separately pivotal in one direction only to the animal to pass and prevented from rotation in the opposite direction. The distance between the gate portions is less than 3.0 feet so as to be less than the length of the animal to prevent an animal being located between the rails and greater than 0.5 feet such that an animal attempting to lift the second fingers cannot simultaneously lift the first fingers.
