looking at fig1 , 4 , 7 , 10 and 14 , several embodiments 20 , 60 , 70 , 90 and 100 of the bedclothes support assembly are illustrated . each of the embodiments 20 , 60 , 70 , 90 and 100 has an upper horizontal member 21 with its ends 22 and 23 supported by a pair of upright members 24 and 25 . the length of the upper horizontal member 21 is equal to or greater than the width 27 of a mattress 28 so that the mattress 28 fits between the upright members 24 and 25 . as shown in fig2 , 5 , 8 , 11 and 15 , the upper horizontal member 21 is supported above the mattress 28 at an elevation substantially higher than the uppermost point of the protected part of the anatomy of the patient . the bedcovers 30 , as shown including linens 31 and a blanket 32 , extend over the upper horizontal member 21 so as to create a cavity 33 around the protected part of the anatomy . the support provided by the upright members 24 and 25 at the ends 22 and 23 of the horizontal member 21 assures that both ends 22 and 23 will be maintained at the desired elevation . the upper horizontal member 21 and the upright members 24 and 25 are further sufficiently rigid so as to substantially prevent deflection of these members 21 , 24 and 25 under the weight of the bedcovers 30 . the bedcovers 30 will not tend to shift toward either end 22 or 23 of the upper horizontal member 21 because neither end 22 or 23 can drop below the other end 23 or 22 . the bedcovers 30 will not tend to shift toward the center of the upper horizontal member 21 because it is sufficiently rigid to resist sagging . therefore , absent application of some exterior force to the bedcovers 30 or to the support assemblies 20 , 50 , 70 , 90 and 100 , the integrity of the cavity 33 will be secure provided the upright members 24 and 25 are adequately supported . the upper horizontal member 21 and upright members 24 and 25 may be of any material and cross - section provided the rigidity and cavity requirements above mentioned are satisfied . however , as best seen in fig1 , 4 , 7 , 10 and 14 , it is preferred that the upper horizontal member 21 and the upright members 24 and 25 be made of ¾ inch pvc pipe with the upper ends 34 and 35 of the upright members 24 and 25 connected to the ends 22 and 23 of the horizontal member 21 by ninety degree elbows 36 and 37 , also preferably made of pvc plastic . an upper horizontal member 21 approximately 36 to 38 inches long will extend across most single bed mattresses . an upper horizontal member 21 approximately 54 – 56 inches long will extend across most double bed mattresses . upright members 24 and 25 approximately 20 to 24 inches long will hold the bedcovers 30 sufficiently above the bottom surface 29 of the mattress 28 or the top surface of the bed frame 29 to provide a sufficient elevation for the cavity 33 to accommodate any part of the patient &# 39 ; s anatomy . in the embodiment 20 of the bedclothes support assembly illustrated in fig1 , 2 and 3 , the upright members 24 and 25 are supported in their vertical condition by a horizontally planar base 40 . the base 40 shown in fig1 , 2 and 3 extends from a lower horizontal member 38 having ends 39 and 41 attached between the lower ends 42 and 43 of the upright members 24 and 25 . the planar base 40 functions like a tongue sandwiched between and abutting the bottom surface 26 of the mattress 28 and the top surface of the bed frame 29 . it should be noted , by reference to fig2 , that this embodiment 20 of the bedclothes support assembly is free - standing . that is , when placed on a horizontal surface , the assembly will remain in its upright condition and is not reliant upon any external structures to remain in the upright condition . sandwiching the base 40 between the crosswires of the bed frame 29 and the bottom surface 26 of the mattress 28 locks the bedclothes support assembly 20 in its vertical upright condition . the base 40 can be made of any material and cross - section provided the free - standing capability of the assembly 20 is not compromised . preferably , it consists of three tubular members 44 , 45 and 46 connected to each other by ninety degree elbows 47 and 48 and connected to the lower horizontal member 38 by t - junctions 49 and 51 . most preferably , the base 40 is formed from ¾ inch pvc pipe connected by pvc elbows and t - junctions and the ends 39 and 41 of the lower horizontal member 38 are connected to the lower ends 42 and 43 of the upright members 24 and 25 by ninety degree elbows 52 and 53 of pvc plastic . as shown , using ¾ inch pvc pipe , the elbows 52 and 53 can be seated on the horizontal flanges 54 and 55 and between the vertical flanges 56 and 57 of the bed frame 29 . a second embodiment 60 , illustrated in fig4 , 5 and 6 , is substantially identical in all respects to the embodiment 20 illustrated in fig1 , 2 and 3 except that the base 40 extends both forwardly and rearwardly of the lower horizontal member 38 so as to provide additional stability to the free - standing capability of the bedclothes support assembly 60 . as best seen in fig6 , this can be accomplished by replacing the t - junctions 49 and 51 illustrated in fig3 with four - way junctions 61 and 62 . additional members 62 , 63 and 64 are connected to each other with ninety degree elbows 65 and 66 and the ends of this assembly are connected to the four - way junctions 61 and 62 . in a third embodiment 70 illustrated in fig7 , 8 and 9 , floor - mounted bases support the uprights 24 and 25 in their upright condition . in the preferred configuration shown , the lower ends 42 and 43 of the upright members 24 and 25 have downward extensions 72 and 73 terminating at horizontal cross - members 74 and 75 which may rest directly on the floor or may be supported above the floor by vertical legs 76 and 78 and 77 and 79 . as shown , the cross members 74 and 75 are connected to the downward extensions 72 and 73 of the upright members 24 and 25 by t - junctions 81 and 82 and the legs 76 and 78 and 77 and 79 are connected to the cross members 74 and 75 by ninety degree elbows 83 and 85 and 84 and 86 . the bases can be made of any material and cross - section provided the free - standing capability of the embodiment 70 is not compromised . preferably , the components are made of ¾ inch pvc pipe and compatible pvc elbows and t - junctions . cross - members 74 and 75 having a length or a distance between legs 76 and 78 and 77 and 79 of approximately 9 inches and upright extensions 72 and 73 and legs 76 , 77 , 78 and 79 having a combined length of approximately 12 inches have been found to perform satisfactorily . in a fourth embodiment 90 illustrated in fig1 – 13 , two bed frame mounted bases support the uprights 24 and 25 in their upright condition . in the configuration shown , the lower ends 42 and 43 of the upright members 24 and 25 are connected to cross members 92 and 93 which extend horizontally and in substantially transverse relationship to the upper horizontal member 21 . as best seen in fig1 , the cross - member 92 has a lengthwise slot 94 which is horizontally radially disposed through the lower wall of a tubular portion 95 of the cross - member 92 . the vertical flange 56 extends into the slot 94 as the cross member 92 is seated on the horizontal flange 54 of the bed frame 29 . the tubular member 95 need not necessarily be round or hollow so long as the slot can receive the vertical flange 56 . the cross member 93 is identical to the cross member 92 illustrated in fig1 . the cross members 92 and 93 may be of any material in cross section provided the free - standing capability of the embodiment 90 is not compromised . preferably , the cross members 92 and 93 are t - junctions having a horizontal length of approximately three inches or more and are made of pvc plastic . as shown , the t junctions can be extended by use of additional sections of pvc pipe 96 and 98 and 97 and 99 having slots in their lower walls aligned with the slots 94 in the t - junctions 92 and 93 . again , the bases can be made of any material in cross section provided the free - standing capability of the embodiment 90 is not compromised . in a fifth embodiment 100 illustrated in fig1 – 17 , bed frame mounted bases support the uprights 24 and 25 in their upright condition . the embodiment 100 is in all respects the same as the fourth embodiment illustrated in fig1 – 13 except that the cross - members 102 and 103 have lengthwise slots 104 which are through a horizontally radial side wall of the cross members 102 and 103 . thus , the cross members 102 and 103 can be engaged on the horizontal flanges 54 and 55 by insertion of the inside edges of the horizontal flanges 54 and 55 into the slots 104 of their respective cross members 92 and 93 . as best seen in fig1 , the horizontal length of the cross members 92 and 93 can be extended by use of additional segments of pipe 106 and 108 and 107 and 109 which can be added to their respective cross members 92 and 93 . the various embodiments of the bedclothes support assembly herein illustrated and described have been generally dimensioned to accommodate a single bed . however , the bedclothes support assembly can be used with any size bed , from single to king size , with appropriate variations in the width of the assembly . thus , it is apparent that there has been provided , in accordance with the invention , a bedclothes support assembly that fully satisfies the objects , aims and advantages set forth above . while the invention has been described in conjunction with specific embodiments thereof , it is evident that many alternatives , modifications and variations will be apparent to those skilled in the art and in light of the foregoing description . accordingly , it is intended to embrace all such alternatives , modifications and variations as fall within the spirit of the appended claims .
