#Drg. 1 shows a complete bed unit of normal size.

#Drg. 2 shows a complete oversize bed unit.

#Drg. 3 shows a bottom base frame with swivel wheels.

#Referring to FIGS. 3, 4, 5 comprising of six sectional frames 41, 43, 43a, 45 with corner posts 41a, 45a denotes a larger diameter size tubing. Referring to frames 42, 44, 44a, 46 with corner posts 44b denotes a smaller size tubing. Frames 41, 43, 43a, 45 with corner posts 41a, 45a denotes telescoping within another and signifies a complete base frame 20. Referring to swivel sheels 69 secured to frame FIG. 1 with bolts 72 and nuts 72a, brackets 108 secured to frame 41 and signifies weight of recipient using bed frames FIGS. 1, 2 will prevent frames 41, 42 from sagging or binding. Referring to FIGS. 1, 2, frame sections 41-46 is assembled and secured with shaded pins 68 and keys 68a inserted in holes 108a secures frame 20. Removing pins 68 and keys 68a and telescoping frames 41-46 to the required alignment holes denotes adjusting frame 20. Refer to a pre-drilled mounting plate 38FIG. 2 denotes repositioning drive train 70 and denotes changing the length of reciprocation for two different length frames 50-50a. The plate 38 is secured to brackets 108 and holes 89.

#Referring to FIG. 9 repositioning L brackets 78 denotes repostioining the length of frame 20 and plate 65 with nuts 66a and bolts 66c and denotes a fixed attachment when repositioning plate 65. Referring to power components for reciprocating frames 50-50a FIG. 1 denotes a gear box motor 21 and drive pulley 22 which turns belt 23. To prevent belts from slipping on pulley's, self adjustment assemblies 32a, 37a when motor is energized, pressure is applied to belts by means of pivot arms 33 secured with pins 34 attached to tension springs 36, 37 secured to support arms 35, 35a. The drive pulley 25 turns belt 29 to reduction pulley 26 that turns crank wheel 27. A view of two drive train assemblies 70, 70a FIGS. 1, 2 show the required length of reciprocation. The normal size frame 50 attached to crank wheel hole 84c and bearing hole 109a to arm 47 and arm bearing 109, secured to pins 84 and keys 84a. When the longer distance of reciprocation is required for taller recipients, frame 50a FIG. 7 means replacing frame 50. Referring to FIG. 2 is the longer distance of reciprocation, by repositioning train assembly denotes predrilled holes 89 in plate 38, FIG. 8 and using belt 29. The arm 28 secured to wheel hole 84d to bearing hole 109b. The arm bearing 109 in arm 28 secured with pins 84 and keys 84a. Referring to components of 70a FIG. 8, support brackets 30 denotes securing pillow blocks 79 and bearings 79a with bolts 39. Inserting shaft thru bearings 79a with pulley's 24, 25 to each end of shaft, denotes turning belt 29 and pulley 26. Referring to train 70 is identical to components in 70a except brackets 31 are longer, denotes clearance of undercarriage of frames 50-50a. Referring to belt supports 56-62 denotes belt attachments to the body limbs to manually adjustable buckles 63 to u-bolts 66 secured to predrilled mounting plates 64-65 denotes interchangeable holes 67a FIG. 9 which indicates securing either u-bolts 66 or automatically controled forward-reverse motors 76. with belt wheels 76a and belts 77 which signifies automatically lifting and lowering the body limbs by means of a motor control 86 FIG. 8. Also a timer control 85 denotes energizing frames 50-50a at any given time and a off-on switch 87 to overide all electrical controls.

#Referring to foot and head supports 52FIGS. 1, 2 secured to frames 50-50a with foot support 52a and head support 53 denotes adjusting to the length of recipients body and secured with wing. bolts 52b. The upper and lower body belts 54, 55 means assisting foot supports 52a and head supports 53 for recipients incapable of supporting their body or extremely heavy recipients from sliding in the direction of the lifting motion. Referring to channel brackets 74FIG. 4 when hinged down over frames 44, 44b frames 43, 43a will be identical, which means the longer frame 50a with wheels 48 secured to brackets 49FIG. 10 will reciprocate the longer distance required. Also FIG. 10, the undercarriage of frames 50-50a with pillow blocks 79 and bearings 79a and shafts 92 turns wheels 48 on tracks 44.
