US 4754511 AAbstract
1. A lightweight, shapable cushioning apparatus which is easily conformable to a desired configuration for supporting an item comprising:exterior surface means of a material stretchable in two directions for forming a desired shape for the apparatus and defining an internal cavity therein; and a plurality of lightweight, resilient, solid, expanded rounded thermoplastic particles substantially completely filling said internal cavity, said rounded particles capable of compression, deformation and three-dimensional movement throughout the internal cavity to allow shaping of the apparatus for support of an item, said rounded particles further capable of returning to their rounded shape after the item to be supported is removed from the apparatus; said exterior surface means and rounded particles capable of easily conforming to the desired configuration while also providing softness, lightweight and washability features to the apparatus. 2. The apparatus of claim 1 which further comprises external means for prestressing said exterior surface means.
10. A lightweight shapable cushioning apparatus which is easily conformable to a desired configuration for supporting an item comprising:exterior surface means of a material stretchable in two directions for forming a desired shape for the apparatus and defining an internal cavity therein; means for adjusting a dimension of said shape, said adjusting means extending through said internal cavity for forcing one dimension of said exterior surface to any position located between an elongated position and a compressed position, a first end of said adjusting means attached to said surface means with a second end of said adjusting means extending through said exterior surface means to facilitate operation of said adjustment means; and a plurality of lightweight, resilient solid, expanded, rounded thermoplastic particles substantially completely filling said internal cavity, said particles capable of compression, deformation and three-dimensional movement throughout the internal cavity without interference from the adjustment means to allow shaping of the apparatus for support of an item, said particles further capable of returning to their rounded shape after the item to be supported is removed from the apparatus; said exterior surface means, adjustment means and particles capable of easily conforming to the desired configuration while also providing softness, lightweight and washability features to the apparatus. 11. The apparatus of claim 10 which further comprises external means for prestressing said exterior surface means.
16. A lightweight, shapable cushioning apparatus which is easily conformable to a desired configuration for supporting an item comprising:exterior surface means of a flexible, fabric material stretchable in two directions for forming a desired shape for the apparatus and defining an internal cavity therein, a portion of said exterior surface means being of a non-stretchable fabric material to assist in obtaining a desired shape for the apparatus; and a plurality of lightweight, resilient, solid expanded, rounded thermoplastic particles substantially completely filling said internal cavity to retain said exterior surface means in the desired shape, said particles capable of reversible compression, deformation and three-dimensional movement throughout the internal cavity without interference to allow shaping of an apparatus for support of an item, said particles further capable of returning to their rounded shape after the item to be supported is removed from the apparatus; said exterior surface means and rounded particles capable of easily conforming to the desired configuration while also providing softness, lightweight and washability features to the apparatus. 17. The apparatus of claim 16 wherein said rounded particles are spherical and a majority of said particles have a diameter of between about 1/64 and 1/2 inch.
18. A lightweight, shapable cushioning apparatus which is easily conformable to a desired configuration for supporting an item comprising:exterior surface means of a flexible, fabric material stretchable in two directions for forming a desired shape for the apparatus and defining an internal cavity therein; frame means of a substantially rigid material located within the internal cavity to assist in maintaining the desired shape of the apparatus; and a plurality of lightweight, resilient, solid, expanded, rounded thermoplastic particles substantially completely filling said internal cavity to retain said exterior surface means in the desired shape, said rounded particles capable of compression, deformation and three-dimensional movement to allow shaping of the apparatus for support of an item, yet further capable of returning to their rounded shape after the item to be supported is removed from the apparatus. 19. The apparatus of claim 18 wherein a majority of said rounded particles are spheres having a diameter of between about 1/64 and 1/2 inch.
21. A lightweight, shapable cushioning apparatus which is easily conformable to a desired configuration for supporting an item comprising:exterior surface means of a material stretchable in two directions for forming a desired shape for the apparatus and defining an internal cavity therein; means for adjusting a dimension of said shape, said adjusting means extending through said internal cavity for forcing one dimension of said exterior surface to any position located between an elongated position and a compressed position, a first end of said adjusting means attached to said surface means with a second end of said adjusting means extending through said exterior surface means in a more than one location to facilitate operation of said adjustment means; external means for prestressing said exterior surface means; and a plurality of lightweight, resilient, solid, expanded rounded thermoplastic particles substantially filling said internal cavity, said particles capable of compression, deformation and three-dimensional movement through the internal cavity without interference from the adjustment means to allow shaping of the apparatus for support of an item, said particles further capable of returning to their rounded shape after the item to be supported is removed from the apparatus; said exterior surface means, adjustment means and particles capable of easily conforming to the desired configuration while also providing softness, lightweight and washability features to the apparatus. 22. The apparatus of claim 21 wherein said exterior surface means is a natural or synthetic fabric and wherein the adjusting means passes through the surface means in at least three locations.
Expanded or foamed thermoplastics are preferred due to their springiness, resiliency, and ultra-light weight. If spheres of these materials are compressed, they will substantially return to their original shape after the compressive force has been removed. Thus, the spheres contribute to the invention in that they are easily capable of movement or deformation to allow shaping of the cushion. If they are deformed, these spheres do return to their original configuration reasonably well after the item to be supported is removed from the pillow. This also enables the cushion to be easily shaped, since the spheres can easily be moved through the internal cavity without interference from the tension elements or draw-cord. In addition, the use of such expanded thermoplastics in conjunction with lightweight covering materials enables an extremely ultra lightweight overall cushion to be provided. For example, a 14"�10"�10" box-like cushion containing expanded polystyrene spheres having diameters between 1/8 and 1/4 inch with a Lycra Spandex fiber blend of 40.8% cotton, 35.4% Lycra, and 23.8% nylon as the outer surface material and Lycra Spandex tension members would weigh approximately 131/2 ounces. This is a significant improvement in weight compared to the much heavier pillows of the prior art.
