For concise illustration of the present invention, hereunder only the lowerleg supporting rack 20, as an example, is given for discussion.FIGS. 2 and 3 are cross-sectional view and exploded view of a part of the lowerleg supporting rack 20. As shown inFIGS. 2 and 3 , the lowerleg supporting rack 20 is composed of aframe 30, a supportingcloth 40, afirst clamping member 50 and asecond clamping member 60. - The
frame 30 has a rectangular shape having parallel and longitudinally arrangedfirst rod 31 andsecond rod 32, and parallel and transversally arrangedthird rod 33 andfourth rod 34. Therods first rod 31 is taken as an example for discussion. Thefirst rod 31 has a circular cross-section. Thefirst rod 31 is further provided with aninner edge 311 facing an inner portion 301 (hollow center) of theframe 30, atop edge 312 facing upwardly, anouter edge 313 opposite to theinner edge 311, and abottom edge 314 facing downwardly. In other embodiments, therods 31 to 34 may have a rectangular cross-section or specific-shaped cross-section. - The supporting
cloth 40 has a supportingportion 41 for supporting mattress and bearing weight, a first connecting portion, namelyfirst bending portion 44, extending downwardly from a firstlateral side 42 of the supportingportion 41 and attached on theinner edge 311 of thefirst rod 31, and a second connecting portion, namelysecond bending portion 47, extending downwardly from a secondlateral side 43 of the supportingportion 41 and attached on theinner edge 321 of thesecond rod 32. For the supportingcloth 40, woven or nonwoven cloth made of plastic material, such as nylon, or natural material, such as cotton or linen, may be used. - The
first clamping member 50 is an elongated sheet member made of metal or plastic material. Thefirst clamping member 50 has an arc-shaped cross-section, such that thefirst clamping member 50 can be smoothly attached on theinner edge 311 of thefirst rod 31. Thefirst clamping member 50 is provided with three throughholes 52, through which threefasteners 54 are inserted. For thefasteners 54, bolts, screws, rivets or other equivalent members may be used. In this embodiment, thefasteners 54 are realized as bolts having threaded shanks inserted through the throughholes 52 and thefirst bending portion 44 of the supportingcloth 40 and screwingly threaded into thefirst rod 31, such that thefirst clamping member 50 is fixedly mounted to thefirst rod 31 of theframe 30 and thefirst bending portion 44 of the supportingcloth 40 is tightly clamped between thefirst clamping member 50 and thefirst rod 31. - Similarly, the
second clamping member 60 is fixedly mounted to thesecond rod 32 of theframe 30 in a way that thesecond bending portion 47 of the supportingcloth 40 is tightly clamped between thesecond clamping member 60 and thesecond rod 32. - With the above-mentioned structure, the supporting
