     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 7 thereof, a new and improved blanket elevator apparatus embodying the principles and concepts of the present invention and generally designated by the reference numerals 10 and 10a will be described. 
     More specifically, the blanket elevator apparatus 10 of the instant invention essentially comprises a cooperating bed frame having bed frame spaced side rails 11 of conventional construction, wherein a plurality of bed mattress members 12 are mounted upon the bed frame. A U-shaped clip 13 is mounted to each of the side rails 11 (it is indicated that only one such U-shaped clip 13 is indicated in FIG. 1, but it should be understood that a mirror image identical such U-shaped clip 13 is mounted to the opposing bed frame side rail 11), with the U-shaped clip having an entrance opening 14 to receive an associated side rail 11 within the clip, with generally U-shaped ends 15 defining the extremities of the U-shaped clip, with a U-shaped front flange 17 fixedly mounting a base tube 16 thereon, with the base tube projecting above the U-shaped clip, such that the base tube includes cooperating aligned base tube bores 23, with the base tube bores positioned in a spaced relationship relative to the clip 13 to provide manual access to a lock pin 22 without interference from the clip structure 13. A U-shaped frame 18 is provided having spaced parallel frame legs 19, with each of the frame legs 19 received within an individual one of the base tubes 16. The U-shaped frame 18 includes a connecting leg 21 extending substantially orthogonally between the frame legs 19, with each of the connecting legs 21 having a row of adjustment apertures 20 directed therethrough. In this manner, the adjustment apertures 20 are aligned with the base tube bores 23 and the lock pin 22 directed therethrough to provide for elevational positioning of the U-shaped frame 18 relative to an uppermost mattress 12, whereupon a blanket member (illustrated in FIG. 7) is merely positioned over the U-shaped frame 18 to space the blanket from an individual&#39;s legs in use. 
     The apparatus 10a, as indicated in FIG. 7, is arranged to provide for enhanced support of the blanket 39 positioned over a modified U-shaped frame 18a, with additionally, a blanket lock plate 26, of the type as indicated in the FIGS. 4 and 5, employed to secure the periphery of the blanket 39 against the mattress structure 12 to arrest the blanket and its movement relative to the mattress structure. 
     The modified U-shaped frame 18a includes a modified connecting leg 21a telescopingly arranged with additional lateral support tubes 24 also of telescoping construction to provide for accommodation of various mattress widths in use. 
     The blanket lock plate, of a type as indicated in the FIGS. 4 and 5, includes a plate top wall 35, with a plate rear wall 27, spaced plate side walls 28, and a plate front wall 29. A U-shaped groove 30 extends coextensively along the plate side walls 28 and the front wall 29, as the forward surface of a U-shaped flange 38 orthogonally projecting below the lock plate side and front walls 28 and 29, such as indicated in the FIGS. 4-6. In this manner, the U-shaped flange 38 provides for an abutment to a lowermost mattress 12 to properly align and orient the lock plate structure 26 relative to the spaced mattresses in use, such as indicated in the FIG. 7. A connecting flange 31 extends orthogonally from the ends of the U-shaped groove 30 at the side walls 28, with each of the connecting flanges 31 having a flange aperture 32. A resilient tether line 36 is provided, having tether line hooks 37 at each end of the tether line, with each of the hooks 37 arranged for reception within an individual one of the flange apertures 32 to thereby capture the blanket 39 between the resilient tether line 36 and the U-shaped groove 30 and arrest its relative movement relative to the mattress structure 12, as well as to the apparatus 10a. The lock plate 26 further includes extension legs 33 extending beyond the rear wall 27 colinearly with the plate side walls 28, such that each of the extension legs 33 terminates in a leg tube 34 oriented orthogonally relative to the plate top wall 35, such that each leg tube 34 is arranged to receive an individual one of the frame legs 19 therethrough to interlock the blanket lock plate structure 26 relative to the U-shaped frame structure 18a. 
     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.
