Abstract
A bridging apparatus for spanning the space defined between two relatively movable structural floor members includes anchor sections adapted to be mounted to the edges of the floors and a two part bridging unit having outer edges pivotally connected to the anchor members. One inner edge of a bridging member includes a spaced pair of legs defining a groove arrayed at an acute angle to the floor, the other bridging member including a tongue riding in the groove. The upper leg of the member defining the groove is wedge-shaped the upper surface of the leg being parallel to the floor structures when the same are aligned horizontally.
