Expansion joint cover

An expansion joint cover for bridging an expansion gap between first and second building floor members has a pivot frame adapted to be affixed to the first building floor member, the pivot frame including a base portion and a longitudinally continuous bearing of spherical cross-section supported by and located above the base portion, and a slide frame adapted to be affixed to the second building floor member. A cover unit is pivotally mounted in spaced-apart relation to a proximal end thereof on the bearing in cantilevered relation to the bearing, is adapted to span the gap, and has a distal end supported on the slide frame. A plurality of spaced-apart compression spring units engaged between the base portion of the pivot frame and a portion of the cover unit intermediate the proximal end and the bearing bias the cover unit about the bearing so as to forcibly engage the distal end of the cover unit with the slide frame.
