A multi-function and automatic sick bed which allows a patient to place his (or her) head, arms, legs, and feet at a most comfortable position comprising: (a) a base frame comprising two longitudinal rods and two horizontal rods connected together to form a substantially rectangular frame having four corners, and four castors mounted under the four corners, respectively, of said base frame to provide said base frame with a mobil function; (b) a bottom layer bed frame being mounted above said base frame by means of a plurality of first vertical supports, second vertical supports, and first connecting rods; said bottom layer bed frame being a rectangular rigid flat frame having a top portion, a middle portion and a bottom portion said first vertical supports being affixed to said base frame, said second vertical supports being affixed to said bottom layer bed frame, and said first vertical and second vertical supports being movably connected by said first connecting rods; (c) a middle layer bed frame above said bottom layer bed frame comprising a left bed frame, a right bed frame, a rear bed frame and a front bed frame, wherein (i) said left bed frame and said right bed frame being two opposite and symmetrical members; said left bed frame having an inner side and an outer side, the inner side of said left bed frame being pivotally connected to the middle portion of said bottom layer bed frame to allow the outer side of said left bed frame to pivot upward, said right bed frame having an inner side and an outer side, the inner side of said right bed frame being pivotally connected to the middle portion of said bed bottom layer bed frame to allow the outer side of said right bed frame to pivot upward, (ii) each of said rear bed frame and said front bed frame having an inner and an outer side, the inner side of each said front bed frame and said rear bed frame being also hinged to the middle portion of said bottom layer bed frame so as to allow the outer side of each of said front and rear bed frames to be lifted upward; (d) a top layer bed frame disposed vertically above said left and right bed frames and said front and rear bed frames, said top layer bed frame comprising two front frames, two mid-front frames, two mid-rear frames, and two rear frames, each pair of said two front frames, said two mid-front frames, said two mid-rear frames and said two rear frames are hinged together to allow pivotal movement therebetween, said two front frames and said two mid-front frames, and said two mid-rear frames and said two rear frames are also respectively hinged together to allow pivotal movement with respect thereto; (e) a bed elevating mechanism mounted under said bottom layer bed frame comprising a first motor, a first screw rod, a pair of second connecting rods, a longitudinal rod and a first sleeve, said longitudinal rod is connected to said two second vertical supports through said pair of second connecting rods respectively, and said sleeve being adapted to cause a horizontal movement of said longitudinal rod, whereby when said first motor is actuated, said first screw rod and said first sleeve will cause a horizontal movement of said longitudinal rod so as to cause vertical movements of said second vertical supports, thus allowing said bottom layer, middle layer and top layer bed frames to be lifted upward or downward; (f) a left elevating mechanism and a right elevating mechanism for tilting left side and right side, respectively, of said top layer and middle layer bed frames, said left and right elevating mechanisms being mounted under said bottom layer bed frame, and each of said left and right elevating mechanisms comprising a second motor, a second gear assembly, a second screw rod, a second sleeve and third and fourth connecting rods, said fourth connecting rod being affixed to said left or right frame, said second motor being connected to said left or right frame via said second screw rod, said second sleeve, and said third and fourth connecting rods in such a manner that when said second motor is actuated, said fourth connecting rods will be lifted upward or downward to cause said left or right bed frame to pivot about the inner side thereof; and (g) a front elevating mechanism and a rear elevating mechanism for tilting front end and rear end, respectively, of said top layer and middle layer bed frames, said front and rear elevating mechanism being mounted under said bottom layer bed frame, and each of said front and rear elevating mechanisms comprising a third moter, a third gear assembly, a third screw rod, a third sleeve, and fifth and sixth connecting rods, said sixth connecting rod being affixed to said front or rear frame, and said third motor being connected to said top or rear frame of said middle layer bed frame via said third screw rod, said third sleeve, and said fifth and sixth connecting rods in such a manner that when said third motor is actuated, said sixth connecting will be lifted upward or downward to cause said front or rear bed frame to pivot about the inner side thereof.
