     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1-6 thereof, a new tilting bed apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the tilting bed apparatus 10 of the instant invention comprises support framework including a first end wall 11 spaced from a second end wall 12, with a pair of spaced side walls 13 extending therebetween. At least one of the side walls 13, and preferably both of the side walls, includes a row of side wall apertures 14 oriented between the first and second end walls 11 and 12. Support legs 15 extend from the comer intersection of the side walls with the first and second end walls to space the side walls and end walls above an underlying support, such as a floor or the like. 
     A bed frame 16 having bed frame side rails 17 and a first end rail 18 spaced from a second end rail 19 is provided. The second end rail 19 includes a frame hinge 16a mounted to the second end rail and to the second end wall 12 to hingedly mount in a pivotal relationship the bed frame 16 relative to the side walls 13. A support leg 20 having first and second ends includes a pivot axle 21 pivotally mounting the support leg 20 to one of the side rails 17, with the second end of the support leg 20 having a peg 22 received selectively with one of the side wall apertures 14. It may be desirable to employ support leg 20 mounted to each of the bed frame side rails 17, in a manner as illustrated in FIG. 2, to provide for additional support. 
     A mattress pad 23 is arranged for securement to the bed frame 16. Spaced hook and loop fastener strips 24 are mounted onto the bed frame side rails 17 and arranged for selective securement to the mattress pad 23 that in turn is formed of a fibrous material to permit adherence of the hook and loop fastener strips 24, thereby selectively securing the mattress pad to the frame 16. 
     Mounting legs 25 are provided and are fixedly mounted to the first end rail 18 to extend upwardly therefrom beyond the mattress pad 23, as best illustrated in FIGS. 2 and 3. The mounting legs 25 support a cylindrical container 26 which is mounted in a fixed relationship relative to the mounting legs. The cylindrical container includes a cylindrical container axis 26a, as shown in FIG. 1, which is substantially parallel relative to the mattress pad 23. 
     With reference now to FIG. 5, it can be shown that the cylindrical container 26 further includes a container floor 27 receiving a support disc 28 thereon. The support disc 28 is rotatably mounted about a support disc axle 29 that is directed coaxially through an aperture in the container floor aligned with the axis 26a. The axle is provided with a bearing 30 interposed between the container floor 27 and the support disc 28 to permit free rotation of the support disc 28 with respect to the cylindrical container 26. The support disc is provided with a central recess 31 arranged to receive a flange 32 therewithin. A tube 33 is fixedly mounted to the flange 32, with the tube 33 projecting through the both support disc 28 and through the container floor 27 to engage the support disc axle 29 while rotatably capturing the support disc therebetween. In this manner, the flange 32 provides a stable rotative mounting of the support disc 28 relative to the container floor 27. 
     The support disc 28 includes a support disc hook and loop fastener surface 34 arranged for securement to a resilient pad 35. More specifically, the rear wall 37 of the resilient pad is provided with a hook and loop rear wall surface, as illustrated in FIG. 5. The resilient pad 35 includes a front wall 38 having plural pairs of straps 47 (see FIG. 3) to receive an individual&#39;s feet therethrough for securement of the individual to the resilient pad 35, as well as to the cylindrical container 26. In this manner, a person may secure his feet within the straps 47, whereby a tilting of the apparatus 10 may then be commenced. When a desired angle has been reached, the support legs may be engaged to corresponding side wall apertures to secure such an angle. The person may then comfortably sleep at such inclined angle and, because of the rotational mounting of the straps as described above, even turn or rotate into any desired position. In addition, is contemplated that cooperative footwear and releasable mounting plates be secured to the support disc in place of the foot straps to effect a more secure engagement between the person and the support disc. 
     To effect a tilting of the apparatus, a pivoting means is provided. FIG. 4 indicates the use of a gear sector 43 fixedly mounted to the bed frame 16, such that the gear sector cooperates with a drive motor 44 having a drive motor gear 45, with the drive motor gear 45 rotatably mounted about a drive motor axle 46, such that upon rotation of the drive motor gear 45 effects pivoting of the bed frame 16 into a desired position. 
     Additionally or alternatively, if desired, the pivoting means may take the form of a pneumatic chamber 48 oriented between the bed frame 16 and the side walls 13 of the support structure, as indicated in FIG. 7, such that inflation of the mounting chamber 48 by a manual or electric pump 49 effects positioning of the bed frame in a pivoted orientation in lieu of or in addition to the use of the support legs 20. 
     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.
