This patent application is a continuation-in-part of co-pending International Patent Application No. PCT/CN2023/073510, filed Jan. 28, 2023, the disclosure of which is incorporated herein by reference in its entirety.
TECHNICAL FIELDThe present disclosure relates generally to mattress assemblies. More specifically, the present disclosure relates to an elastomeric grid layer used in mattress assemblies.
BACKGROUNDA mattress' construction is one of the factors that will impact its unique feel. There are various types of mattresses. One type of mattress includes a pillow top mattress that has a “floating” layer of upholstery that feels similar to having a giant pillow on top of the mattress. Pillow top mattresses may range from medium to very soft in feel. Another type of mattress includes an all-foam mattress, which can be made using some combination of polyurethane foam, memory foam, and/or latex foam. The memory foam will typically be positioned close to the sleeping surface to yield the best benefit. A further type of mattress includes a hybrid mattress that use an innerspring as a support core and added layers of specialty foam (memory foam or latex foam) on top. Hybrid mattresses provide the active support of an innerspring with the unique feel of specialty foam materials.
It is well known that one of the challenges in the mattress industry is to create a mattress that provides comfortable support to all portions of a human body. It is desirable to achieve a level of comfort that reduces localized pressure points in areas of the human body, such as shoulders, hips, back, and legs. In recent years, the mattress industry has developed mattresses pads that incorporate a combination of gel, pillow top padding, and foam layers that can conform to contours of a human body to provide support. Typically, the gel layer extends over the entire width and length of the mattress. However, the disadvantage of incorporating pillow-top padding, gel, and/or foam layers is that there exists a greater propensity for sagging mattresses and mattresses developing depressions. Also, the gel layer can increase the overall weight of the mattress.
Accordingly, there is a need in the art for an improved mattress that provides a comfortable mattress having a long useful life with increased stability. The present disclosure addresses this and other related and unrelated issues.
SUMMARYThe present application relates to a thermoplastic elastomer grid designed to overcome drawbacks of the prior art and provide a mattress that has stability and a simple structure.

For example, the flex foam encasement 134 may be constructed of four pieces 134a, 134b, 134c, and 134d that together define the center opening 148. The four pieces 134a, 134b, 134c, and 134d may be fixedly coupled to one another by fastener, adhesive, frictional engagement of the pieces 134a, 134b, 134c, and 134d themselves, or combinations thereof. In other examples, the flex foam encasement 134 may be formed by more or less pieces.
During assembly, the flex foam encasement 134 may surround the first, second, third, fourth, fifth, and sixth cushion elements 136, 138, 140, 142, 144, 146 to provide a perimeter thereabout.

The dividers 156 may have a different material composition than that of the flex foam encasement 134. The dividers 156 may be mounted within the center opening 148 in perpendicular relation to major sides 158 of the flex foam encasement 134 and parallel to minor sides 160 of the flex foam encasement 134, although alternatives are possible. As such, the dividers 156 may be oriented perpendicular to a longitudinal axis X of the flex foam encasement 134 and attach to the major sides 158 of the flex foam encasement 134, although alternatives are possible.

The cut out portions 312 can be in a variety of shapes such as, but not limited to circular, square, rectangular, triangular, star-shaped, hexagonal, octagonal, pentagonal, oval, etc. In the example shown in
The individual cushion elements 310 are inserted into a respective one of the cut out portions 312. No adhesive or glue is used to secure the individual cushion elements 310 within the cut out portions 312. The individual cushion elements 310 may have the same size and shape as the cut out portions 312 so that each individual cushion elements 310 may be firmly, but releasably, retained in the appropriate cut out portions 312 through frictional forces. The individual cushion elements 310 may each be positioned into a respective cut out portion 312 without creating uncomfortable ridges or creases that might be felt by the user. The symmetrical and uniform design of the elastomeric layer 302 allows for the desired comfort, stability and balance in the mattress assembly 300. For example, a desired comfort can be achieved at the head region, hip region, and leg region of the mattress assembly 300.

The individual cushion elements 310 may each include a cylindrical, rod-shaped element 314 at its center and a plurality of interconnected side wall segments 316 extending from the cylindrical, rod-shaped element 314 about its axis. The plurality of interconnected side wall segments 316 also extend at various angles to an outer circumferential wall 318 of the individual cushion element 310.
In certain examples, the plurality of interconnected side wall segments 316 can be angled with respect to each other to provide a plurality of polygon shaped members. In certain examples, the plurality of interconnected side wall segments 316 can be angled with respect to each other to provide a plurality of pentagon-shaped members in addition to other polygon shapes. It will be appreciated that the interconnected side wall segments 316 of the individual cushion elements 310 may be arranged to form other shapes such as quadrilateral, hexagon, heptagon, octagon, etc.
