Having means biasing gate about pivot:

(under subclass 599.1) Barrier means which is swung about its connection and held either in or out of its obstructing positions by a biasing force stored in either (a) a separate spring or (b) an integral, resilient* extension of the barrier means which does not itself act as a barrier.
