Abstract: A support rail for springs as might be used in a spring assembly such as a bedding or seat foundation. The support rails are metal and form part of a frame to which the springs are mounted. The support rails have a generally inverted U-shape and include a pair of spaced upright webs with a load carrying plate extending between and located below the upper ends. The plate is further defined by a base and side sections which curve outwardly and upwardly from the base before connecting to the upper ends of the webs. The curves of the side sections define inwardly facing receptacles located immediately below a necked area of reduced width. The support rails are utilized with springs that include at least one mounting portion shaped to snap mount into the receptacles upon downward insertion into the load carrying plate. Features are also provided to limit longitudinal movement of the springs relative to the support rails once mounted.
Abstract: A furniture seat spring assembly is presented which allows simplicity and economical seating for chairs, sofas or the like. The spring assembly comprises a U-shaped base having an eccentrically positioned coil spring which is covered with an elastic webbing. The eccentric position of the spring allows the user's weight to depress the webbing without "feeling" the coil spring which is positioned near the seat frame front rail. Multiple assemblies are positioned at selected intervals within conventional seat frames, depending on the particular frame size used.
Abstract: A box spring includes a border frame with an opening therethrough and spaced and parallel slats extending thereacross, a wire grid spaced from and parallel with the border frame and slats, and a plurality of springs extending between the wire grid and the border frame/slats, wherein the internally located springs have ends which are secured to plastic clips, and each of these clips is removably secured to one of the slats via a snap-on connection. Each of the clips also has a hook for removably retaining a spring portion. The snap-on connections of these spring holding clips, and additionally, the hooks for removable spring retention, facilitate interconnection of the wire grid to the border frame/slats. The snap-on clips of this invention reduce the costs associated with construction and assembly of a box spring, while providing secure interconnection of the internal springs.
Abstract: A bedding foundation frame for use in manufacturing a bedding foundation. The foundation frame includes side rails and end rails formed into a rectangular configuration and a plurality of slats extending between the side rails and parallel to the end rails. Selected ones or all of the slats are reinforced by sheet metal strips positioned in juxtaposition to the bottom of the reinforced slats with a longitudinally extending flange in the central portion of the strip extending upwardly into a longitudinally extending slot in the center of the bottom face of the reinforced slat. These sheet metal strips, because of the presence of the flange in the sheet metal strip, function to provide additional resistance to bending of the slats under normal loads while simultaneously preventing breakage of those slats under abnormal loads.
Abstract: A frame for a spring assembly has a plurality of parallel transverse cross rails with mounting slots that form openings through the top portion of the cross rail. Springs are firmly secured to the cross rails by inserting foot portions of the springs into the mounting slots by a simple press fit.

Abstract: An elastomeric hanger structure is designed to provide both force stabilization and vibration isolation while connecting a part such as a vehicle exhaust system with a supporting structure such as a vehicle chassis. The elastomeric hanger of the invention is also capable of being selectively tailored to control numerous static and dynamic conditions which may be encountered when the part is suspended.
Abstract: A foundation unit having a top bearing grid structure secured to a bottom substructure by intermediate support elements. The grid structure comprises a series of spaced longitudinal and transverse spring elements, each spring element being formed to permit elastic elongation thereof. Elastic elongation is accomplished by a series of V-shaped segments in each of the spring elements, the segments being located at the intersections of the spring elements and being joined by a clip. The support elements comprise wire elements which are L-shaped and which are composed of two planar portions connected at right angles to one another. The wire elements are located in transverse rows with the orientation of the wire elements in each row being opposite to the orientation of the wire elements in the adjacent row so that loads applied to the foundation unit are balanced.
