[0032] With reference now to the drawings, and in particular to FIGS. 1 through 6 thereof, a new heated air mattress embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

[0033] As best illustrated in FIGS. 1 through 6, the heated air mattress 10 generally comprises a device for positioning on a conventional massage table 70. The massage table 70 has a platform 72 and a plurality of legs 74. The platform 72 has a back edge 76 having a pair of wells 78 extending therein.

[0034] The device 10 includes an air mattress 12 having a top wall 14, a bottom wall 16, a back wall 18, a front wall 20, a first side wall 22 and a second side wall 24. Each of the walls of the air mattress 12 is substantially flexible. An air valve 26 for filling the air mattress 12 with air is coupled to the top wall 14 and extends into an interior of the air mattress 12. It should be understood, the air mattress may also include water filled mattresses, or mattresses which have a resiliently flexible material such as a foamed elastomeric material in place of the air. A distance between the first 22 and second 24 side walls is substantially equal to 30 inches. A distance between the back 18 and front 20 walls is substantially equal to 72 inches. These measurements are conventional measurements of a massage table and may vary within 12 inches for both measurements. A height of the air mattress 12 is generally between ¾ inch and 1 inch when the air mattress is filled with air to a pressure greater than one atmosphere. The height is generally less than 1 inch so that the edges of the device to not cover the edges of the person who is being massages, and thus hindering the massage.

[0035] A pillow portion 28, or headrest, has an upper wall 30, a lower wall 32, and a peripheral wall 34 extending between and integrally coupled to the upper 30 and lower 32 walls. Each of the walls of the pillow portion 28 is substantially flexible. An air valve 26 for filling the pillow portion 28 with air is coupled to the upper wall 30 and extends into an interior of the pillow portion 28. As with the mattress, the headrest may be filled with a foamed elastomeric material or water. The pillow portion 28 has a generally U-shaped, or C-shaped, cross-section taken along a plane extending through the peripheral wall 34 and is orientated generally parallel to the upper 30 and lower 32 walls.

[0036] A coupler for removably coupling the pillow portion to the massage table includes a plate 36. The plate 36 generally has a shape substantially identical to the lower wall 32 and is securely coupled to the lower wall 32. Each of a pair of rods 40 is securely coupled to the plate 36. Each of the rods 40 extends in a generally parallel direction. The rods are of a standard size which may be extended into conventional wells 78 of a massage table 70.

[0037] A tube 42 for carrying water into the air mattress is elongated and has a first end 44 and a second end 46. The tube 42 is positioned in the air mattress 12. Each of the first 44 and second 46 ends of the tube 42 extends outwardly through the front wall 20 of the air mattress 12. The portion of the tube 42 within the air mattress is securely attached to an inner surface of the top wall 14. The portion of the tube within the air mattress ideally weaves about the top wall as shown in FIG. 2. The portion of the tube within the air mattress has a break therein such that a third end 48 and a fourth end 50 of the tube 42 is defined. Each of the third 48 and fourth 50 ends extends outwardly through the back wall 18 of the air mattress. The third 48 and fourth 50 ends may be fluidly coupled together.

[0038] Each of the first 44 and second 46 ends of the tube 42 is fluidly coupled to a water heating and pumping device 52. The water heating and pumping device 52 is adapted for heating water positioned in the tube and circulating the water in the tube 42. The water heating and pumping device 52 is conventional and is preferably coupled to the massage table 70.

[0039] A conduit 54 for carrying water into the pillow portion 28 is elongated and has a first end 56 and a second end 58. The conduit 54 is positioned in the pillow portion 28. Each of the first 56 and second 58 ends of the conduit 54 extends outwardly through the peripheral wall 34 of the pillow portion 28. The portion of the conduit 54 in the pillow portion 28 is securely attached to an inner surface of the upper wall 30. Each of the first 56 and second 58 ends of the conduit may be fluidly coupled to one of the third 48 and fourth 50 ends of the tube 42. The areas where the tube 42 extends through the air mattress and the conduit 54 extends through the pillow portion are airtight so that the mattress and pillow do not lose their air. FIGS. 3 and 4 depict different orientations of the conduit 54.

[0040] In use, the device 10 is positioned on a massage table 70 as shown in FIG. 1. The water heating and pumping device 52 is turned on so that water positioned in the tube 42 circulates about the air mattress 12 and pillow portion 28 to warm each of them for the comfort of the person on the massage table 70. The device 10 may be used without the massage table 70.
