Abstract

The present invention relates to a gelatinous composite article. The article has a first and a second heat formable and heat reversible gelatinous elastomer material, a first permeable layer, and a control gap. Each of the gelatinous materials is a three-dimensional shape having an upper side, a base side and at least one connecting side. The first connecting side and the second connecting side are adjacent to each other so the first and second materials are essentially side-by-side within the same horizontal plane. The first permeable layer has a top side and a bottom side. The top side attaches to the first and second connecting side. The control gap is interspaced between the bottom side of the first permeable layer. This gap degrades the rigidity between each connecting side and provides an equivalent structural property throughout the article.

Claims

1. A gelatinous composite article in a mattress unit comprising:

a foam crib in the mattress unit divided into an upper crib and a lower crib;

a sealant layer that melts within a first temperature range;

a first permeable layer over the sealant layer that attaches to the underside of the upper foam crib and melts at a second temperature greater than the first temperature range;

a first heat formable and heat reversible gelatinous elastomer material over the first permeable layer that fuses to the sealant layer within the first temperature range thereby securing the permeable layer to the gelatinous layer and the first material to the upper crib;

a second heat formable and heat reversible gelatinous elastomer material having a set of apertures within the lower crib; and

a second permeable layer having a palm-base attached to the underside of the lower crib, and a set of finger-like structures wherein each finger-like structure secures the second material to the lower crib by having each finger inserted into a corresponding aperture to the top side of the lower crib wherein the distal part of the finger-like structure fuses between the top side of the lower crib and the sealant layer to secure the second material to the mattress unit.

2. The gelatinous composite article of claim 1 wherein the permeable layer is selected from the group consisting of polyester and non-woven nylon.

3. The gelatinous composite article of claim 1 wherein the sealant layer is selected from the group consisting of a polyolefin, adhesive, nail, velcro, magnetism, and screws.

4. The gelatinous composite article of claim 1 wherein the gelatinous elastomer material comprises a high viscosity triblock copolymer of the general configuration poly(styrene-ethylene-butylene-styrene).

5. The gelatinous composite article of claim 1 wherein the first temperature ranges between 250°

and 450°

F.

6. The gelatinous composite article of claim 1 wherein the area of the permeable layer is greater than the area of the gelatinous elastomer material.

7. The gelatinous composite article of claim 1 wherein the foam crib comprises the upper foam crib, the lower foam crib, and an adhesive material;

the adhesive layer is between the upper and lower foam cribs, and attaches the first and second permeable layers to the foam crib.

8. The gelatinous composite article of claim 1 wherein the foam crib is along the perimeter of the heat formable and heat reversible gelatinous elastomer material.

9. The gelatinous composite article of claim 1 wherein the distal portion of each of the finger-like structures has an aperture.

10. The gelatinous composite article of claim 1 wherein the palm-base portion of the second permeable layer has apertures.

11. The gelatinous composite article of claim 1 wherein the first gelatinous elastomer material is a first section and a second section, each section has a three-dimensional shape, the shape has an upper side, a base side and at least one connecting side, the first connecting side and the second connecting side are adjacent to each other so the first and second sections are essentially side-by-side;

a first permeable layer having a top side and a bottom side, wherein the top side attaches to the first and second connecting side; and

a control gap interspaced between the bottom side of the first permeable layer to degrade the rigidity of between each connecting side and provide an equivalent structural property throughout the first gelatinous elastomer material.

12. The gelatinous composite article of claim 1 wherein the second gelatinous elastomer material is a first section and a second section, each section has a three-dimensional shape, the shape has an upper side, a base side and at least one connecting side, the first connecting side and the second connecting side are adjacent to each other so the first and second sections are essentially side-by-side;

a first permeable layer having a top side and a bottom side, wherein the top side attaches to the first and second connecting side; and

a control gap interspaced between the bottom side of the first permeable layer to degrade the rigidity of between each connecting side and provide an equivalent structural property throughout the first gelatinous elastomer material.
