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.
Claims5
An apparatus for bridging a span defined between two relatively movable structural floor members comprising first and second elongate anchor units adapted to be mounted to the opposed edges of the respective said floor members and a bridging unit formed of first and second elongate bridge members, each said bridge member having a captive end pivotally connected to a respective said anchor unit for movement about a horizontal axis and a free end, the free end of said first bridge member including upper and lower spaced legs defining therebetween a groove upwardly inclined at an acute angle to the plane of said floor members, the free end of said second bridge member being downwardly inclined at said acute angle and slidably received within said groove, said upper leg being wedge-shaped in transverse section, becoming progressively thicker in the direction from said free end toward said captive end, the upper surface of said upper leg lying substantially in the plane of said floor members when said floor members are in coplanar alignment.
