## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a therapeutic mattress system and more particularly pertains to strategically creating holes for pressure relief purposes.
2. Description of the Prior Art
The use of cushioning devices of known designs and configurations is known in the prior art. More specifically, cushioning devices of known designs and configurations previously devised and utilized for the purpose of cushioning a user through known methods and apparatuses are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.
By way of example, U.S. Pat. No. 1,742,186 issued Jan. 7, 1930 to Claus relates to a cushion. U.S. Pat. No. D411,933 issued Jul. 13, 1999 to Bernstein relates to a modular maternity mattress system. Lastly, U.S. Pat. No. 6,523,198 issued Feb. 25, 2003 to Temple relates to a modular medical-bed mattress with underlying bed pan.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe therapeutic mattress system that allows strategically creating holes for pressure relief purposes.
In this respect, the therapeutic mattress system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of strategically creating holes for pressure relief purposes.
Therefore, it can be appreciated that there exists a continuing need for a new and improved therapeutic mattress system which can be used for strategically creating holes for pressure relief purposes. In this regard, the present invention substantially fulfills this need.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of cushioning devices of known designs and configurations now present in the prior art, the present invention provides an improved therapeutic mattress system. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved therapeutic mattress system and method which has all the advantages of the prior art and none of the disadvantages.
To attain this, the present invention essentially comprises a generally rectilinear bloc. The block is made of an elastomer. The elastomer is selected from a class of elastomers. The class of elastomer includes rubber and plastic, natural and synthetic, and blends of rubber and plastic. The elastomer is preferably a closed cell polyurethane foam. The block has a horizontal top surface, a parallel bottom surface and a vertical peripheral surface between the top and bottom surfaces. The block has an upper edge, a lower edge and parallel side edges between the upper and lower edges. The block also has a height, a width, and a thickness. The height is between about 175 and 225 percent of the width. The width is between about 500 and 700 percent of the thickness.
A plurality of apertures are provided. The apertures are cut into the block. The apertures include a central aperture. The central aperture is in the general configuration of an isosceles right triangle with slightly curved sides. The sides of the triangle include a base side. The base side is located midway between the side edges and closer to the upper edge than to the lower edge. The base side is between about 30 and 40 percent of the width of the block. The sides of the triangle also include two leg sides. An apex is located midway between the side edges and closer to the lower edge than to the upper edge.
The apertures also include a plurality of ovals. Each of the ovals has a long major axis and a short minor axis. The ovals are arranged in pairs. One pair of ovals has its major axes aligned in proximity to the base side of the triangle. Each of the other two pairs of ovals have their major axes aligned in proximity to the leg sides of the triangle respectively. In this manner the major axes of the three pairs of the ovals form an isosceles triangle around. The isosceles triangle is congruent with, the isosceles right triangle of the central aperture. Each aperture has vertical sides. The vertical sides extend between the top and bottom surfaces. At least 30 percent of the block, measured from the upper edge, is devoid of apertures. At least 30 percent of the block, measured from the lower edge, is devoid of apertures.
Provided last is a plurality of inserts. The inserts are fabricated of the same material as the block. The inserts are of a size and shape corresponding to the size and shape of the apertures. In this manner each aperture may be selectively filled with an insert so that all of the apertures may be simultaneously filled for maximizing pressure on a user. In the alternative, none of aperture may be filled with an insert for minimizing pressure on a user. In the alternative, preselected apertures may be selectively filled with inserts at the discretion of the user for the selective application of pressure.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be betters appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims attached.

The present invention, the therapeutic mattress system 10 is comprised of a plurality of components. Such components in their broadest context include a generally rectilinear block, a plurality of inserts and a plurality of apertures. Such components are individually configured and correlated with respect to each other so as to attain the desired objective.
First provided is a generally rectilinear block 12. The block is made of an elastomer. The elastomer is selected from a class of elastomers. The class of elastomer includes rubber and plastic, natural and synthetic, and blends of rubber and plastic. The elastomer is preferably a closed cell polyurethane foam. The block has a horizontal top surface 14, a parallel bottom surface 16 and a vertical peripheral surface 18 between the top and bottom surfaces. The block has an upper edge 20, a lower edge 22 and parallel side edges 24 between the upper and lower edges. The block also has a height 26, a width 28, and a thickness 30. The height is between about 175 and 225 percent of the width. The width is between about 500 and 700 percent of the thickness.
A plurality of apertures are provided. The apertures are cut into the block. The apertures include a central aperture 32. The central aperture is in the general configuration of an isosceles right triangle with slightly curved sides. The sides of the triangle include a base side 34. The base side is located midway between the side edges and closer to the upper edge than to the lower edge. The base side is between about 30 and 40 percent of the width of the block. The sides of the triangle also include two leg sides 36. An apex 38 is located midway between the side edges and closer to the lower edge than to the upper edge.
The apertures also include a plurality of ovals 40, 42, 44, 46, 48, 50. Each of the ovals has a long major axis and a short minor axis. The ovals are arranged in pairs. One pair of ovals 40, 42 has its major axes aligned in proximity to the base side of the triangle. Each of the other two pairs of ovals 44, 46 and 48, 50 have their major axes aligned in proximity to the leg sides of the triangle respectively. In this manner the major axes of the three pairs of the ovals form an isosceles triangle around. The isosceles triangle is congruent with, the isosceles right triangle of the central aperture. Each aperture has vertical sides. The vertical sides extend between the top and bottom surfaces. At least 30 percent of the block, measured from the upper edge, is devoid of apertures. At least 30 percent of the block, measured from the lower edge, is devoid of apertures.
Provided last is a plurality of inserts 52, 54, 56, 58, 60, 62, 64. The inserts are fabricated of the same material as the block. The inserts are of a size and shape corresponding to the size and shape of the apertures. In this manner each aperture may be selectively filled with an insert so that all of the apertures may be simultaneously filled for maximizing pressure on a user. In the alternative, none of aperture may be filled with an insert for minimizing pressure on a user. In the alternative, preselected apertures may be selectively filled with inserts at the discretion of the user for the selective application of pressure.
As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
