  • Figure eight hinge
    Patent number: 6112369
    Abstract: The figure eight hinge of the present invention allows a gate to be quickly and safely attached to a support structure. The hinge includes two legs having two different radii of curvature. The legs also include a slot which allows the hinge to have the desired figure eight configuration. The present invention advantageously eliminates pinch points and minimizes the distance between the gate and the support structure. In particular, the hinge remains stationary with respect to the support structure while allowing the gate to rotate within one end of the hinge. The figure eight hinge is preferably used with animal enclosures such as kennels or pens because it reduces the risk that an animal will catching its feet or other body parts between the gate and the support structure.
