The abstract is neither intended to define the invention of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way. 
     It is therefore an object of the present invention to provide a new and improved water bed sheet arrangement which has all the advantages of the prior art sheet construction and none of the disadvantages. 
     It is another object of the present invention to provide a new and improved water bed sheet arrangement which may be easily and efficiently manufactured and marketed. 
     It is a further object of the present invention to provide a new and improved water bed sheet arrangement which is of a durable and reliable construction. 
     An even further object of the present invention is to provide a new and improved water bed sheet arrangement which is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such water bed sheet arrangements economically available to the buying public. 
     Still yet another object of the present invention is to provide a new and improved water bed sheet arrangement which provides in the apparatuses and methods of the prior art some of the advantages thereof, while simultaneously overcoming some of the disadvantages normally associated therewith. 
     These together with other objects of the invention, along with the various features of novelty which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and the specific objects attained by its uses, reference should be had to the accompanying drawings and descriptive matter in which there is illustrated preferred embodiments of the invention.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 10 thereof, a new and improved water bed sheet arrangement embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the water bed sheet arrangement 10 of the instant invention essentially comprises positioning within a water bed 11 having a water bed mattress 12 of fluid filled construction. The mattress 12 is mounted within a container frame 13 having frame side walls and a container frame foot board 13a. A first sheet member 14 and a second sheet member 15 are arranged coextensively relative to one another positioned to a top surface of the mattress 12. The first sheet member and the second sheet member 14 and 15 respectively include respective first and second sheet member first side edges 16 and 17 that overlap in a parallel relationship, as illustrated in the FIGS. 1 and 2 for example. A row of button members 18 is mounted to the second sheet 15 adjacent the second sheet first side edge 17 received through button receiving slots 19 directed through the first sheet 14 adjacent the first sheet members first side edge 16 to permit selective securement of the first and second sheets together. 
     Optionally, a lower seam 21 is directed along the overlap of the first and second side edges 16 and 17 extending from a first sheet lower edge 22 and a second sheet lower edge 23 that in turn is positioned below the mattress 12 to permit securement of the sheet structure relative to the mattress structure. 
     As illustrated in the FIGS. 6 and 7, a flexible corner plate 24 is positioned below the mattress 12 at corners of the mattress adjacent the foot board 13a. The corner plate 24 is mounted to secure the second side edges relative to the lower edges of the sheets adjacent the foot board for positioning under the mattress to provide for proper orientation of the sheets mounted to the mattress structure. FIGS. 8-10 illustrate that each of the corner plates 24 (for purposes of illustration, only one such corner plate is illustrated but it is understood that the identical construction is arranged for securement to the first sheet member 14) includes a matrix of conical resilient projections 25 extending into communication with a bottom surface of the mattress 12 to enhance positioning of the corner plates to minimize displacement of the corner plates relative to the associated mattress structure. 
     As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall 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.
