Portable cushion and method of use

Abstract

A seating system for a chair in the form of a deflatable cushion. The two-inch-thick cushion, divided into nine rectangular sections, will have an open-end casing comprised of viscoelastic foam. The air compressor, connected to the battery power source, shoots pressurized gas into a check valve and then into branched rubber tubings. The sequence of deflation is as follows: pressurized gas passes through the air compressor's plastic compartment, which encases antibacterial liquid that the gas can pass through before entering the check valve. Having exited the air compressor and entered the check valve, the valve will regulate the flow of air to the cushion based on synchronization with the compressor and electronic feedback from the application or manual control. Having entered the check valve, the pressurized, sanitary gas enters the rubber tubings and the porous rubber tubes' eight subsections. This will cause deflation of the cushion. In addition, a heat sensor will be on the top-layer of the cushion and it can be linked to a computer for the user to monitor which areas of contact are too high in heat.

(15) FIG. 1 shows one embodiment of the present invention in an exploded form. The present inventive cushion 100 is illustrated. As shown the horizontal surface of the cushion 5 is preferably designed to be semi-pliable but formed to hold the shape of substantially an outer edge wall. Horizontal surface 5 can be comprised of a plurality of materials both natural and synthetic. Horizontal surface 5 forms the upper face of the cushion upper cover 6. As shown in some embodiments, upper cover 6 is defined by vertical walls 10 and horizontal surface 5.

(16) As shown inner cushion 15 is preferable designed to be a hollow frame with a top surface 16 and side wall edge 17. Inner cushion 15 is designed to comfortably and pliably support a user. The upper top surface 16 is preferably constructed with perforations or pores 20 designed for the egress of air and gas exiting the cushion compartments.

(17) Further shown is the bottom hoard 30 of one embodiment of the present invention. As shown three gas tubes 40, 41, 42 and preferably arranged in parallel such that the ends of the tubes exit off of the bottom board 30 and may attach to the air tube 50. As shown, air containment modules 35a, 35b, and 35c are attached to tube 40 and designed to hold the air in compartments without spreading, with the goal being to keep air in the varying compartment combinations. As shown, air containment modules 36a, 36b, and 36c are attached to tube 11 and designed to hold the air in the appropriate compartment. As shown, air containment modules 37a, 37b, and 37c are attached to tube 42 and designed to hold the air in the appropriate compartment. The vertical edge 45 of cushion pad with pipes is preferably designed to support the weight of a user.

(18) As shown air tube 50 separates into two different passages to attach to tubes 40 and 41 in the cushion. Likewise, tube 50 attaches to air tube 55 designed to move air towards the cushion for distribution while in use. Further shown, compartment 56 can carry medication inside of it and humidify it into the air that Will flow into tube 55. Pipe 58 connects the air pump 60 to the medication container, or compartment 56. Air pump 60 is an air pump/air compressor as is known in the industry. 62a and 62b are electrical wires from the battery, indicated by 90 on the drawings, to power the air pump 60. Electrical wire 65 is covered in a sheath to protect it in the manner normally known in the art.

(19) Receiver 70 is also attached to the air pump 60. The purpose of the receiver is to receive the signal from the remote and convert the signal to instructions to the pump. Wire 75 that connects the remote control 80 to the receiver 70. Wire 85 connects the receiver 70 to the battery 90.

(20) FIG. 2 illustrates one embodiment of the present invention in assembled form. As shown upper cover 6 in mechanically place over inner cushion 15 and attached to bottom board 30 (FIG. 1). In many embodiments, these three elements are attached as a single functional unit. Further shown are the two connection ports 150 and 250 on the exterior of one side of the connection between the tube 50 and the cushion wall 10. Subsections 6a-6i are the sections of top cushion 6 which have varying air mists pushed through the perforations located on the surface of the cushion mesh cover 120.

(21) FIG. 3 illustrates one embodiment of the present invention in partial transparency. Medicated air 200 is being released from the pores 20 on the inner cushion 15 and then through the perforations on subsections 6a-I on the top cushion 6. FIG. 4 shows the additional divider walls 131, 132, 133, 134, 135, 136, 137, 138 and 139, which have orifices designed have the tubes 40, 41, and 42 pass through them in a tight seal such that air cannot escape between divided sections. The sections 106a-i are further defined by dividing walls 141, 142, 143, 144, 145, and 146 which are substantially in airtight seal with the corresponding adjacent walls. In each section 106a-i there is air containment module that is in electronic communication with controller 80. During operation is it envisioned that individual controllers can be activated individually to allow air to flow into each individual subsection 160a-i. Further drawing of the sections 106a-i included in FIG. 4.

(22) FIG. 4 illustrates one embodiment, of the interior frame 115 shown inner cushion 15 is preferable designed to be a hollow frame 115 with a top surface 16 and side wall edge 17 (FIG. 1). Inner cushion 15 is designed to comfortably and pliably support a user. The upper top surface 16 is preferably constructed with perforations or pores 20 designed for the egress of air and gas exiting the cushion compartments. FIG. 4 shows the additional divider walls 131, 132, 133, 134, 135, 136, 137, 138 and 139, which have orifices designed have the tubes 40, 41, and 42 pass through them in a tight seal such that air cannot escape between divided sections. The sections 106a-i are further defined by dividing walls 141, 142, 143, 144, 145, and 146 which are substantially in airtight seal with the corresponding adjacent walls. In each section 106a-i there is air containment module that is in electronic communication with controller 80. During operation is it envisioned that individual controllers can be activated individually to allow air to flow into each individual subsection 106a-i. Further drawing of the sections 106a-i included in FIG. 4.

(23) FIG. 5 illustrates a partial cross sectional side view of one embodiment of the present invention. As shown, tube 41 is attached to air containment module 36a, b, and c through port 43. Tube 41 is attached to inner cushion 15 through port 47. The ports 47 and 48 are left open for the air to openly flow from the tubes to the cushion 15. Ports 42 and 43 are controlled by 35b and 36b. When allowed by 35b and 36b, air will flow into the tubes 41 and 40. As shown, tube 40 is attached to air containment module 35a through port 42. Tube 40 is attached to inner cushion 15 through port 48. Also shown is the empty air vacuum space between the two tubes (40, 41).

(24) FIG. 6 illustrates one embodiment of the present invention with a user 2000 sitting on the inventive cushion 100. As shown the user 2000 is sitting in a wheelchair 1000 which is a wheelchair s known commonly in the art. A wheelchair provides the user the ability to be mobile. It can be either manually powered or automated, and in this case, it is manually powered. The user 2000 is holding remote control 80 and the control 80 is attached to receiver 70 as is earlier described. Inventive cushion 100 is in a deflated mode in this illustration.

(25) FIG. 7 illustrates one embodiment of the present invention in which the cushion 100 is inflated with air to the highest capacity. That is why the individual (2000) is elevated in contrast to FIG. 5. These two figures were included to show the variance of the cushions inflation levels.

(26) While preferred embodiments have been shown, and described, modifications thereof can be made by one skilled in the art without departing from the scope or teaching herein. The embodiments described herein are exemplary only and are not limiting. Many variations and modifications of the system and apparatus are possible and will become apparent to those skilled in the art once the above disclosure is fully appreciated. For example, the relative dimensions of various parts, the materials from which the various parts are made, and other parameters can be varied. Accordingly, it is intended that the following claims be interpreted to embrace all such variations and modifications.
