Abstract
Dual spring support structures for mattresses or other reflective support structures employ foam springs in combination with inner springs or foam cores to provide multimodal and multi-structured support surfaces with multiple, invariant or identical spring coefficients and support properties. Foam springs have a geometric cross-sectional arrangement with mechanical spring properties that act in combination with the spring properties of the foam. In one embodiment foam springs are used around the wire foam inner spring or around the foam core. The foam spring may have a spring factor that is equal to, greater than or less than that of the inner spring or core. Foam springs of different arrangements and spring coefficients are used alone or in combination with different shaped cores to provide a spring or cushion structure.

This application claims priority to US provisional patent application 61 / 022,041, filed January 18, 2008.
Field of invention
The present disclosure and related inventions relate to mattresses and more specifically to mattresses having multimodal and multistructured support surfaces having multiple, constant or identical spring coefficients and support properties.
Metal springs, foam layers, solid foam blocks, water, air and other structures have been used in the mattress construction. These materials can be used separately or in combination. Mattresses are constructed with varying degrees of firmness to provide supports of different degrees and shapes. The edge portion of the mattress, i.e. the horizontal support surface close to the vertical sidewall, is an important part of the structure to prevent the tendency to roll-off or taper down toward the edge and to resist seat pressure. . If built more than necessary, the transition between the edge of the mattress and the inner spring may be abrupt or uncomfortable. The mattress edges typically do not provide much support to the seater in this seated position. In addition, having a stronger and better supporting mattress in relation to the sleeping area extends the sleeping area so that consumers can sleep at or near the edge without inconvenient and uneven transition between the inner spring and the mattress edge.
The present disclosure provides mattresses with edges that provide a stronger and better supporting seat edge that creates an even transition and contributes to the overall comfort and support of the entire mattress.
Summary of the Invention
A foam spring and inner spring combination is disclosed that includes a foam spring component used in the edge region of a mattress proximate the edge or core of a mattress inner spring. One aspect of the present disclosure and related invention is a foam spring that acts as an internal component of the mattress as both a foam element and a support element. The foam spring includes one or more first segments extending in a first direction that are interconnected with one or more second segments extending in a second direction, and the foam springs include the interconnection of the first and second pieces and As a result of relative motion, it has both mechanical spring action and foam cushion support properties, and foam spring action results from the compressibility and elastic material properties of the foam from which the foam spring is made.
Another aspect of the present disclosure and related inventions is a combination of
A further aspect of the present disclosure and related invention is the combination of foam springs with inner springs, where one or more pieces of foam springs are close to or approximately close to the inner springs, such as wire-shaped inner springs with multiple springs or coils. Wherein the surface of the foam spring is adjacent to the support surface or horizontal plane of the inner spring and compressible with respect to the inner spring, wherein the spring coefficient of the foam spring is similar to or the same as the spring coefficient of the inner spring, or intentionally internal It is made different from the spring coefficient of the spring.
Another aspect of the present disclosure and related inventions includes a mattress having an internal spring and a multimodal and multi-structured support surface having a multi-, invariant, or the same spring coefficient and support properties as the surrounding foam structure acting alone and in combination. do.
These and other aspects of the disclosure and related inventions are further disclosed herein and claimed as claims in connection with the accompanying drawings of specific, preferred and alternative embodiments of various inventive concepts.
