  • Patent number: 10905246
    Abstract: A pocketed spring, such as that used in a mattress, comprises: a compression spring having an upper end convolution and a lower end convolution opposite the upper end convolution, and a plurality of helical intermediate convolutions between the upper end convolution and the lower end convolution; a flexible enclosure including a top wall positioned adjacent to the upper end convolution of the compression spring, a bottom wall positioned adjacent to the lower end convolution of the compression spring, and a side wall that extends from the top wall to the bottom wall; and a tension member connected to the flexible enclosure. The tension member acts in opposition to the compression spring until the pocketed spring is compressed to a point at winch the tension member no longer applies any force. Thus, the pocketed spring exhibits a non-linear response when compressed.

    Abstract: Encased hourglass coils and encased hourglass coil mattress cores have steel wire coils with an hourglass profile encapsulated in a sheet material enclosure, package, casing, housing, containment or encapsulation, wherein coils are enclosed within an enclosure made of fabric, non-woven, or other material which encapsulates each individual coil spring and serves to maintain multiple coil springs in an array or alignment in a mattress core. The hourglass configurations of the coils, wherein at least one helical convolution of the coil body located between the coil ends has a diameter which is less than every other convolution of the coil body, provides a mattress core which has a relatively lower spring rate upon initial compression and a higher spring rate at higher compression loads.
