  • Patent number: 8904584
    Abstract: A cellular cushioning system includes cells or support units arranged in one or more stacked arrays. The cells are hollow chambers that resist deflection due to compressive forces, similar to compression springs. The arrays are attached to one or more intermedial binding layers. The intermedial binding layer(s) links the cells together while allowing the cells to deform independently of one another. An external load compresses of one of the void cells within an independent compression range without significantly compressing at least one void cell adjacent the compressed void cell. The independent compression range is the displacement range of the compressed void cell that does not significantly affect the compression of adjacent void cells. If the void cell is compressed beyond the independent compression range, the intermedial binding layers may be deflected and/or the void cells adjacent the compressed void cell may be compressed.

  • Patent number: 7426766
    Abstract: A tufted air mattress including a first printed sheet and a second sheet. The first printed sheet is printed over a selected area with an ink containing a fluoropolymer. The portion of the printed sheet with the ink defines a coated area. The first printed sheet attached to the second sheet where the printed sheet is not coated with the ink. The coated area of the printed sheet inhibits heat welding of the first sheet to the second sheet. The coated area also lubricates the first and second sheets to aid in inflating the air mattress without flaking and contaminating the air inflating the air mattress. In one embodiment of such a mattress, three sheets define two air volumes that are alternatingly inflated and deflated through an alternating air supply valve.

The air chamber is defined by top and bottom sheet panels and a valve allowing air passage into and out of the air chamber. The foam panel includes apertures therethrough, and the top and bottom sheet panels are mechanically coupled directly together via the apertures in the foam panel. As a result, the foam panel need not be mechanically connected to the top and bottom sheet panels and improved air flow within the chamber results. Furthermore, by virtue of the direct mechanical coupling between top and bottom sheet panels distributed throughout the air mattress, the top and bottom sheet panels are limited in their relative spacing and the air mattress tends to better support any weight placed thereon, there being no pillowing of the air mattress in response to weight placed thereon.

  • Patent number: 5655239
    Abstract: Generally, the present invention is directed to a cellular air loss mattress system comprising an air mattress and an air supply means. Cells of the mattress system are welded onto a unitary top piece and a unitary bottom piece. Means for supplying air, preferably an air blower, is connected to the center cell (also referred to as the pelvic cell) via a supply hose. The air exiting the air blower travels through the supply hose and fills the center cell. The air is allowed to directly travel into adjacent cells via internal air connectors. The inner diameter of each air connector is adjusted to create different pressure zones within the air mattress to support the different pressure requirements of a patient's body. The highest pressure zone is the center cell that initially receives air from the air supply means. The pressure decreases as air moves from the center cell to adjacent cells.

  • Patent number: 5515560
    Abstract: A frame for a soft sided waterbed has four rails of foam covered with vinyl or other water impervious sheet. The cover sheet extends completely around each foam rail, and a central portion extends across the frame to the opposite foam rail. A reinforcing sheet can be coextensive with the central portion if needed. The cover sheet is then sealed to itself at each foam rail, so the frame defines a waterproof safety liner integrally therewith. The cover sheet may have holes in each corner, on the bottom of the frame, so the foam rails can be removed and reinserted. This allows the frame to be shipped in "knocked-down" condition and assembled by the user.

  • Patent number: 5173974
    Abstract: An article of furniture which is convertible to form a crib, a youth bed, or an adult bed. The crib is produced through the interconnection of a rear panel, a right side panel, a left side panel, a front panel and a mattress support frame. This interconnection of parts provides a substantially rectangular configuration having the mattress support frame horizontally disposed therein. The front panel is comprised of at least a lower section and an upper gate section. The upper access gate section permits a greater access to the confines of the crib. The crib is converted to a youth bed through the removal of the upper gate section and the downward vertical displacement of the mattress support frame. The lower section functions as a "roll bar" purposed to prevent a toddler from rolling off of the edge of a mattress. The roll bar may be eliminated by inverting the lower section.
