Human cushion apparatus
View Patent ↗The present invention may be used for support of a human on a cushion. A mattress apparatus may have a base member of generally rectangular shape with four upstanding peripheral side walls. A plurality of bars may be disposed on the base member in a rectangular matrix configuration and the plurality of bars may have a separation space longitudinally and laterally between adjacent bars. A gas member of generally elongated tubular shape may be positioned longitudinally in each of the longitudinal separation spaces with each of the gas members having a gas conduit connected to a first pressurized gas source. Lateral gas tubes that may be of generally rectangular shape may be positioned transversally of the longitudinal gas tubes with a first end of each lateral gas tube connected to the first pressurized gas source or to a second pressurized gas source. A bed sheet covering the base member to enclose the top of the mattress apparatus.
1. An apparatus for support of a human on a cushion comprising:
a mattress apparatus having a base member of generally rectangular shape with four upstanding peripheral side walls;
a plurality of bars disposed on said base member arranged in rows and columns in a rectangular matrix configuration and said plurality of bars having a separation space longitudinally and laterally between adjacent bars;
a gas member of generally elongated tubular shape disposed longitudinally in each of said longitudinal separation spaces wherein each of said gas members having a gas conduit connected to a first pressurized gas source;
a plurality of lateral gas tubes of generally rectangular shape disposed transversally of said longitudinal gas tubes wherein a first end of each of said lateral gas tubes is connected to a second pressurized gas source; and
a bed sheet disposed over said base member to cover an upper portion of said mattress apparatus.
2. The apparatus as in claim 1 wherein each of said gas members has a plurality of tube bars attached to an upper surface.
3. The apparatus as in claim 2 wherein said plurality of bars and said plurality of tube bars have cooperatively attached and disposed a plurality of projections on adjacent bars and tube bars to inhibit interference during raising and lowering of said tube bars.
4. The apparatus as in claim 2 wherein said tube bars are sufficient height to be elevated above the height of said bars by inflation of said gas members.
5. The apparatus as in claim 1 wherein a central longitudinal row of said bars has approximately at least twice the width of the remainder of said plurality of bars.
6. The apparatus as in claim 5 wherein at least one of said bars in said central longitudinal row has a reduced height relative to the remainder of said bars in said central longitudinal row.
7. The apparatus as in claim 1 wherein said first pressurized gas source and said second pressurized gas source each have an exhaust port.
8. The apparatus as in claim 1 wherein said four upstanding peripheral side walls have indentations in a top surface.
9. The apparatus as in claim 1 wherein:
a flexible tube is disposed in each of said longitudinal separation spaces adjacent to said gas members;
each of said flexible tubes has a gas aperture; and
each of said flexible tubes is connected to a supply tube that is connected to a third gas pressure source.
10. The apparatus as in claim 9 wherein a fluid container is connected to said supply tube to allow entrainment of a fluid disposed in said fluid container.
11. The apparatus as in claim 1 wherein said bed sheet has a sheet detachably attached to an upper surface.
12. The apparatus as in claim 11 wherein said sheet has a thickness to reduce a user's sensing of said bars, said gas members and said lateral gas tubes.
13. The apparatus as in claim 1 wherein said bars are approximately 2 to 3 inches in height and width, approximately 6 to 8 inches long, and are spaced apart approximately 2 to 3 inches.
14. The apparatus as in claim 1 wherein said plurality of lateral gas tubes has a plurality of apertures therein and a central lateral gas tube of said lateral gas tubes has user body disposed apertures therein.
15. The apparatus as in claim 1 wherein said gas members are approximately 6 inches wide and inflatable to approximately 2 to 3 inches in height.
16. The apparatus as in claim 1 wherein said bed sheet generally encloses said mattress apparatus.
17. The apparatus as in claim 1 wherein said second gas source is actually said first gas source.
18. A method for relief of human body pressure areas using the apparatus of claim 1 comprising inflating and deflating said gas members and said lateral gas tubes for a period of time of 15 minutes to 4 hours.
