  • Patent number: 6792716
    Abstract: A barrier gate includes a crossbar selectively pivoting between a saddle post and anchor post. The crossbar includes a first end and a second end. The first end of the cross bar is pivotally secured to the anchor post such that the second end of the crossbar may be selectively lifted from the saddle post opening the barrier gate and providing access therethrough. The barrier gate also includes a locking mechanism at the first end of the crossbar for permitting the selective locking of the crossbar in a substantially vertically orientation. The barrier gate further includes a counterweight interacting with the crossbar for assisting in the lifting of the crossbar between a closed orientation and an open orientation, and a cable linking the counterweight to the crossbar.
