TI-IERMO-CLOUD ELECTRIC MATTRESS OBJECTS AND ADVANTAGES OF THE PRESENT INVENTION The present invention pertains to bed mattresses, including heating means embedded therein, to provide a very substantial degree of relief for people suffering from various forms of back ailments by stimulating blood circulation and relaxing the muscles.
In practice, the electric bed mattress of the present invention has proven its ability to reestablish a very substantial degree of mobility for persons having back ailments to a degree which seriously impared their ability to walk.
One of the principal objects of the present invention is to provide a thermostatically controlled heating element within a bed mattress to stimulate the blood circulation and to relax the muscles of a person sleeping thereon.
Another principal object of the instant invention is to provide a thermostatically controlled heating element within a bed mattress which is interposed between upper and lower protective pads in the bottom portion of the mattress.
A further object of this invention is to provide a relatively thick resilient pad, such as foam rubber, above the upper protective pad.
A still further object of the present invention is to provide insulation means beneath the lower protective pad including means, such as aluminum foil on the top side thereof to reflect the heat upwardly to the body of a person disposed on the mattress.
Yet another object of this invention is to provide a wool pad atop the foam rubber pad.
Another object of the instant invetion is to provide a fabric cover about the heating element, upper and lower protective pads, the relatively thick resilient pad, insulation means, and wool pad, said cover, for example, beingformed of rayon damask.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a bed mattress in accordance with the present invention;
FIG. 2 is a fragmentary sectional view taken along the line 2--2 of FIG. 1.
DETAILED DESCRIPTION OF THE INVENTION With reference to the drawings in which like reference numerals designate like or corresponding elements throughout the various views, and with particular reference to FIG. 1, the electric bed mattress of the present invention is indicated generally at with electric leads l2 and 14 extending therefrom to a conventional thermostat control (not illustrated).
With reference to FIG. 2, the mattress 10 provides a heating element 16 in the lower portion thereof which is controlled by the thermostat through the leads 12 and 14. A lower pad 18, formed, for example, of cotton protects the heating element from the stiffness of a lower insulating element 20 having means such as an aluminum foil upper side 22 to reflect the heat from the element 16 upwardly. An upper pad 24, similar to the lower pad 18, is disposed between the heating element 16 and a relatively thick resilient pad 26 formed, for example, of foam rubber. A wool pad 28 is preferably disposed atop the resilient pad between said resilient pad 28 and the top portion 30 of a fabric cover 32 surrounding the entire mattress structure. The cover 32 may, for example, be formed of a rayon-damask material.
The heat from the element 16 is radiated upwardly by the foil 22 through the upper pad 24, resilient pad 26, wool pad 28 and top 30 of the fabric cover 32 and provides a very beneficial effect to a person lying thereon in that it relaxes the nerves and stimulates the blood circulation to promote a more restful sleep.
The thermostat is preferably ofa type which provides a substantial number of settings, nine, for example, to provide varied degrees of heat for the comfort of the individual user. Insulating element 20 is preferably formed of paper and prevents humidity, drafts and coldness from passing upwardly through the mattress. In practice the bed mattress of the present invention has proven to be invaluable in promoting a more restful sleep, thereby eliminating many nervous disorders as well as providing a substantial degree of relief for people with arthritic problems.
What is claimed is:
1. An electric bed mattress comprising:
a thermostatically controlled heating element interposed between upper and lower protective pads, fabricated of cotton;
insulating means disposed beneath said lower protective pad;
a relatively thick resilient pad formed of foam rubber positioned above said upper protective pad;
a fabric cover of a material such as rayon-damask fixed about the entire exterior of the mattress assembly;
a relatively thin wool pad interposed between the top surface of said resilient pad and the underside of the top portion of said fabric cover; I
said insulating means comprising an insulated paper structure covered with foil on its top side to radiate the heat from said heating element upwardly through the mattress.
