Abstract
Abstract A seal for a piano hinge for preventing passage of electromagnetic energy through the hinge; said seal comprising a first sealing member of conductive material comprising a connecting section for attachment to and for electrical contact with one hinge leaf and an arcuate section shaped to fit over the hinge knuckles, and a second sealing member of conductive material comprising a connecting section for attachment to and for electrical contact with another hinge leaf and an arcuate section for overlapping and for making electrical contact with the arcuate section of the first sealing member. Preferably the sealing members are of hard copper alloy. Another embodiment includes a detachable sealed hinge assembly wherein the hinge includes three leaves; an attached leaf, an insertion leaf, and an attachable leaf.
