Abstract
An architectural joint system is disclosed, which incorporates a slidably supported arched cover plate to span the open space between two relatively movable structural units. The edge margins of the arched cover plate are slidably received in housings, mounted at the adjacent corners of the structural units. The housing assemblies are formed of base members and cover members assembled to define a narrow gap for the reception of a thin cover plate, and an enclosure for receiving the edges of the plate. The cover members are uniquely designed to have an outwardly and upwardly convergent taper, extending over a substantial distance of at least about two times the thickness of the cover member. The arched plate is of a shallow, upwardly convex contour, closely conforming to the long convergent taper of the cover member. The new construction is a significant improvement over known arched cover type joint systems, in that it presents a substantially inconsequential deviation from a flat, planar surface of the adjacent structures, an important advantage in the construction of floors for hospitals and similar institutions.
