  • Patent number: 6032307
    Abstract: A bedding product comprising a collapsible spring assembly, a pad covering the spring assembly and a fabric covering encasing the padded spring assembly. The spring assembly comprises a plurality of collapsible spring modules connected to a plurality of spaced parallel helical lacing wires and locking means to hold the assembly in an expanded condition and prevent its collapse. Each of the spring modules comprises four individual wires joined together with helical lacing wire wrapped around a center section of each of the wires. Upon the collapse of the assembly, each of the spring modules collapses. The assembly is held in an expanded condition by a plurality of locking rods, pieces of plastic mesh or other locking means.

  • Patent number: 5765240
    Abstract: A bedding product comprising a collapsible spring assembly, a pad covering the spring assembly and a fabric covering encasing the padded spring assembly. The spring assembly comprises a plurality of collapsible spring modules connected to a plurality of spaced parallel connecting rods and locking means to hold the assembly in an expanded condition and prevent its collapse. The parallel connecting rods are located between border rods in the top and bottom planes of the assembly. Each of the spring modules comprises four individual wires joined together with helical lacing wire wrapped around a center section of each of the wires. The center sections of the wires define an axis about which each of the wires are capable of rotational movement. Upon the collapse of the assembly, each of the spring modules collapses rotating around the axis of the module. The assembly is held in an expanded condition by a plurality of locking rods, pieces of plastic mesh or other locking means.

  • Patent number: 5364082
    Abstract: A spring includes upper and lower runs of wire interconnected by an intermediate run of wire, all of the runs being integrally formed from spring wire. The opposite ends of the upper and lower runs respectively include hooks and coils while the intermediate run includes a coil. The hooks and coils of the upper and lower runs are used to connect the spring to an adjacent spring with the hook of one spring being received about the coil of an adjacent spring. The upper and lower runs are offset above and below the coils of the upper and lower runs respectively to accommodate a helical wire which is wrapped around the upper run for interconnecting runner wires which extend transversely of the upper run. The runner wires have offset portions which are secured to the upper runs by the helical wire. In one form the coils in the upper and lower runs are provided with a projecting recess or ear for receiving the hooks of an adjacent spring.

  • Patent number: 4003564
    Abstract: A torsion spring assembly in which the means for mounting the bail portion of the torsion spring to a supporting frame comprises an elongate strip having a bore extending lengthwise therethrough dimensioned to receive the bail portion in seated relation therein, an entrant portion communicating with the bore for guiding the bail into the bore, and slots extending crosswise in the strip spaced one from the other longitudinally in a pair to correspond with the spaced relation between the bar supporting side arms of the torsion spring.

  • Patent number: 3945627
    Abstract: A resilient foundation assembly for furniture expecially a box spring for supporting a mattress. A frame means which defines a generally planar foundation area, a grid means overlaying and spaced in a plane above and generally parallel to the foundation area plane and a plurality of spring units resiliently connected between the frame means and grid means. The spring units are formed of a single length of wire and comprise two end segments and a plurality of dual counter reaction modular coil springs contiguous therebetween. Each dual counter reaction spring comprises two leg sections extending downwardly from the grid plane toward the planar foundation area formed by the frame means, the two leg sections are joined by a bridging segment of wire lying in the grid plane. Each leg section is formed by linear segments of wire positioned in predetermined angular relationships and joined by a coil section of wire.
