  • Patent number: 6649825
    Abstract: A lightning rod system including both methods and specific types of lightning rod protection apparatus, which address the need for lightning rod safety features to deter impalement and minimize injury when humans inadvertently fall upon or strike the projecting air terminal through use of a hebetative contiguous impact surface (10) on an end cap(s). The system involves lightning rod system components such as humanized quantal rod (3) or coil spring coupler (13) engineered to be responsive within the range of forces achieved when a human of average size and weight falls onto the projecting air terminal from a standing surface level with that on which the lightning rod system is mounted to. The lightning rod system also involves a method and engineered components to retrofit existing lightning rod assemblies.
