  • Breakaway sign post connector
    Patent number: 6308927
    Abstract: A breakaway sign post connector includes a shear member and a bushing. The shear member includes a first end, a second end, and a necked down section intermediate the first and second ends. A shoulder is attached to the second end, and a resilient bushing is positioned over the shoulder and surrounds the shear member. When attached to an anchor plate and a support plate for a sign post, the bushing strengthens the connector and resists wind shear while allowing the shear member to fracture in the necked down section at a predetermined impact load.
