  • Electrostatic grounding system for work surfaces
    Patent number: 4945447
    Abstract: An electrostatic grounding system for work surfaces having a covering such as a laminate covering, which includes a conductive layer to carry static charges. The system includes a grounded conductive plug in the work surface. To maximize the area of contact between the plug and conductive layer, the plug has a head with a tapered circumference which may also include ridges to further maximize the area of contact. Also set forth is the plug and a device for grounding a person through the work surface and plug.
