Mounted On Frame Spanning Strips Patents (Class 267/100)
  • Patent number: 9332854
    Abstract: A coil spring bracket assembly that supports a cushion on a furniture frame is disclosed. A flat spring spans the furniture frame along a support plane to support the cushion. A cross member spanning the furniture frame is aligned with and spaced from the flat spring. A helical spring extends from the cross member to the flat spring to bias the flat spring toward the support plane. A bracket is disposed at opposite ends of the cross member to anchor the cross member to the furniture frame. The bracket includes a top portion that extends outwardly over the furniture frame along the support plane, a middle portion that extends from the top portion into the furniture frame, and a bottom portion that extends inwardly from the middle portion to abut a portion of the cross member in overlapping relationship.

  • Patent number: 5639071
    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.

  • Patent number: 5548857
    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.
