Abstract

Abstract An improved bed frame assembly including a pair of parallel side rails and a pair of end cross rails extending perpendicularly between the side rails also includes a central support rail extending parallel to the side rails and midway of the cross rails. The central rail is T-shaped in cross section, having a vertical leg and a pair of horizontal legs extending outwardly from the top of the vertical leg. At least one end of the central rail is connected to a cross rail by means of a plate secured to the midportion of the cross rail. The plate includes a pair of opposed protruding fingers extending horizontally below the plate, and having opposed ends spaced from each other. The fingers define a T-shaped space into which an end of the central rail is inserted, so that an end of each horizontal leg of the central rail is held between a respective finger and the plate, for a positive connection between the central rail and the cross member.
