Abstract
A seismic expansion joint cover assembly installed at a motion-absorbing gap between a member A on one side of the gap and a member B on the other side of the gap includes a cover panel spanning the gap and a hinge joining one edge A of the cover panel to the member A for pivotal movement about a pivot axis. The pivot axis is spaced apart from the expansion gap so as to enable a stop between member A and the cover panel to prevent the cover panel from pivoting about the pivot axis into the expansion gap upon widening of the expansion gap. A permanent magnet and magnet striker releasably secure the other edge B of the cover panel to the member B. A tensioned cable connected between the cover panel and one of the members A and B limits the pivoting movements of the cover panel and automatically recloses the cover panel over the gap.
