  • Patent number: 7665163
    Abstract: A bed frame comprising T shaped side rails provide support for a box spring and mattress. A leg assembly is affixed to the bed frame and is affixed to the side rail and to the cross rails for better strength of connection. The use of T-shaped side rails provides more resistance to twisting and bowing and thereby more resistant to damage a leg or other structural component of the bed frame from moving the bed frame across the floor. The use of the T-shape cross section side rails enables the overall bed frame to support more weight with less deflection than the convention L-shaped side rails. There are also headboard and footboard brackets that take advantage of the greater height of the vertical flange of the side rail to have affixation means, such as rivets, that are further spaced apart to provide a more rigid connection between the brackets and the side rails.

    Abstract: A universal cross member that can be used with a bed frame or bed rails to provide support for a box spring and mattress. The universal cross member has a straight bar with telescoping ends so that the universal cross member can be used even where there are variances in the distance between the side rails and still be fitted to those side rails. A tensioning system is provided to add strength to the universal cross member to eliminate, in almost all instances, the need for some further support of the universal cross member from the floor, such as a caster or a glide. In the system, a tensioning bar has its ends affixed at or near the ends of the straight member and its center contacts a block at a finite distance from the straight member at or about the center of the straight member. By placing the tension bar in a predetermined tension, a force is created that acts through the block against the approximate center of the straight member.
