Referring now in detail to the drawings a combination adjustable side rail and hoist mechanism is generally indicated at 20, and is shown attached to the rails 21 of a conventional bed 22. As shown in FIGS. 5 and 6, the bed rails 21 may be of inverted L-shape having a horizontal leg 23 and a vertical leg 24.

Attached to and extending upwardly from the bed rails 21 are a pair of protective side rails, generally indicated at 25 and 26, disposed on oposite sides of the bed 22 and being normally disposed in spaced panallel relationship.

The side nail 25 comprises a pair of spaced parallel vertical standards 27 and 23 having a rigid horizontal cross bar 29 extending therebetween and integrally secured thereto at a point intermediate the top and middle of the standards 27 and 28.

A railing 30 extends across and is integrally secured to the top of the standards 27 and 28. The opposite ends of the railing 3% are downwardly turned as at 31. As shown in FIG. 1, a series of spaced vertically aligned keeper holes 33 are formed in the outer faces of the standards 27 and 28. These holes 33 are arranged in the lower intermediate portion of the standards for the purpose to be hereinafter more fully described.

The side mail 26 comprises a pair of spaced parallel vertical standards 37 and 38 having a rigid horizontal cross bar 39 extending therebetween and integrally secured thereto at a point intermediate the top and middle of the standards 37 and 38.

A railing 40 extends across and is integrally secured to the top of the standards 37 and 38. The opposite ends of the railing 40 are downwardly turned as at 41.

As shown in FIG. 2, a series of spaced vertically aligned keeper holes 43 are formed in the outer faces of the standards 37 and 38. These holes 43 are arranged in the lower intermediate portion of the standards substantially in alignment with the keeper holes 33 of the side rail 25.

From the foregoing it will be noted that the side rails 25 and 26 are of like construction in so far as the arrangement of their vertical standards 27, 28 and 37', 38, cross bars 29 and 39, railings 30 and 40, and keeper holes 33 and 43, respectively, are concerned, so that said side rails will function to assist in confining a patient within the limits of the bed 22. However, in addition to the cross bar 39, the side rail 26 is provided with a second rigid horizontal cross bar 44 which extends between the standards 37 and .38 as is integrally secured thereto at a point a suitable distance below the cross bar 39.

As shown in FIGS. 2 and 3, a hoisting lever unit or lifter frame 45, comprising a pair of spaced substantially parallel side arms 46 and 47, is provided for reasons presently to be assigned. As shown in FIG. 4, the side arms 46 and 47 may be channels arranged in reverse, such as The cross bar 44 is journalled through openings 48 in the upper portion of the arms 46 and 47 so that the hoisting :lever unit 45 is pivotally connected to the side rail 26.

The side arms 46 and 47 are connected by a pair of cross bars 49 and 50, the cross bar 49 being arranged at a suitable point below the pivotal connection of the hoisting lever unit 45 with the cross bar 44, and the cross bar 50 being arranged adjacent the lower portion of said hoisting lever unit to provide a handle therefor.

An eye bolt 51 extends through the .cross bar 50 intermediate the ends thereof and is secured thereto by a nut 52.

A tie strap 53 has one end detachably secured to the .eye .bolt 51.

ments about the fulcrum provided by the cross bar 44 by an operator actuating the handle bar 50 or the tie strap 53.

A roller 54 is detachably mounted between the side arms 46 and 47 of the hoisting :lever unit 45 in the space between the cross :bars 49 and 50.

The roller 54 comprises an elongated hollow tubular or cylindrical body 55 having a pair of bushings 56 fixedly secured therein in spaced relation from the ends thereof.

Slidably mounted in each of the bushings 56 is the inner end portion of a pin or rod 57 having a stop washer 58 fixedly secured thereon adjacent the outer end thereof.

A coiled spring 59 encircles each pin 57' and has one end bearing against the bushing 56 and its other end bearing against the washer 58.

A cap 60 having a centrally llocated opening 61 is mounted on each end of the roller body '55 and is held in place thereon by means of a screw 62.

Normally the springs 59 urge the pins 57 outwardly so that the washers 58 abut against the inner faces of the caps 60. In this position the outer ends of the pins 57 project a suitable distance from the ends of the roller 54 for engagement in a respective pair of apertures 63 in the side arms 46 and 47, for suspending the roller 54 therebetween. As shown in FIG. 3, a series of vertically aligned apertures 63 are formed in the lower intermediate portion of each side arm 46 and 47 so that the roller 54 can be mounted in a predetermined position in the lever unit 45.

Attached to each bed rail 21 are a pair of clamp supporting brackets 65 for receiving and supporting the side rails 25 and 26.

As will best be seen in FIGS. and 6, each of the brackets 65 has a horizontal leg 66 and an elongated vertical leg 67. The horizontal leg 66 overlies the horizontal leg 23 of the bed rail 21 and the upper portion of the vertical leg 67 is normally disposed in abutting relation to the vertical leg 24- when the brackets 65 are in clamping position.

An aperture 68 extends [through the vertical leg 67 at a point below the bottom of the vertical leg 24 for the reception of a threaded bolt 69.

A flat substantially rectangular clamping plate 70 is provided, having an aperture 71 through which the bolt 69 extends. The clamping plate 70 abuts against the inner face of the vertical leg 24 of the bed 21.

A hand pressure wheel 72 is threadedly engaged on the bolt 69 and bears against the clamping plate 70, when in operative position, to clamp the bracket 65 to the bed rail 21.

A hollow cylindrical sleeve member 73 is fixedly secured to the outer face of the vertical leg 67 adjacent the top thereof, and extends upwardly therefrom. The sleeve 73 has a threaded aperture 74 extending through the outer face thereof. The aperture 74 is axially aligned with a selected one of the keeper holes 33, 43 of the standards 27, 28 and 37, 38, respectively, when the standards are mounted in the sleeve 73.

A threaded locking pin 75 extends through the apertune 74- and a selected one of the keeper holes 33, 43 for locking the side rails 25 and 26 against vertical movement.

Referring now to FIGS. 7 and 8, a separate base 79 is shown for supporting the patient lift without fixedly attaching the same to a bed frame.

The base 79 comprises two supporting units 80 and 81, each having a pair of hollow cylindrical legs 82 and 83. An elongated substantially rectangular bar 84, having apertures 85 and 86 therethrough, is slidably disposed on the legs 82 and 83. Hand pressure wheels 87 are provided for locking the bars 84 in position with the legs 82 and 83. The supporting units 80 and 81 are ad justaibly secured together by telescoping connecting rods 88 and '89. Hand adjustment screws 90 permit lateral adjustment of the connecting rods 88 and 89 for accommodating the base 79 to beds of varying width. Hand adjustment screws 91 are also threadedly engaged in the legs 82 and 83 adjacent the top thereof.

In use, the base 79 is positioned beneath the bed 92, and is locked against accidental movement by tightening the screws 90. The vertical standards or legs of the side rails 25 and 26 of the patient lift are then telescopically engaged into the hollow legs 82 and 83, re spectively, of the-base 79, and the screws 91 tightened, when the lift has been positioned in the desired relationship to the bed.

In FIGS. 9 and 10 another modified form of means for attaching the patient lift to a bed frame is shown. In this embodiment of the invention an elongated sub stantially rectangular bar '93 is provided having a pair of vertical apertures 94 and 95 extending therethrough adjacent the ends thereof.

A hook member 96 is fixedly secured to the bottom of the bar 93 for engagement over the vertical leg 24 of the bed rail 21.

A pair of spaced elongated latching bolts 97 extend through the bar 93 adjacent the top thereof. These latching bolts 97 have one end thereof reverted as at 98 for locking engagement against the horizontal leg 23 of the bed rail 21. The other end 99 of the latching bolts is threaded for the reception of an internally threaded hand pressure wheel 100. p

In use, the bar 93 is attached to the bed rail 21 by placing the hook 96 around the vertical leg 24 of the bed rail 21 and by turning the reverted end 98 of the latching bolt 97 to an engaging position with the horizontal leg 23 of the bed rail 21, and exerting pressure on the hand wheel 100.

The apertures 94 and 95 receive the legs 82 and 83, as in the unit shown in FIGS. 7 and 8, and the legs 82 and 83 receive the patient lift in the same manner as does the unit shown in the aforesaid FIGS. 7 and 8.

In FIG. 11 the unit illustrated in FIGS. 9 and 10 is shown in an inverted position for use with beds wherein the vertical leg 101 of the rail 102 extends vertically upward instead of in a downward direction from the horizontal leg of the bed rail.

In order to hoist a patient to a position above the bed a sling member is arranged crosswise of the bed and supported by the side rails 25 and 26 in the manner shown in FIG. 1.

Various forms of slings may be used, such as the sling 108 illustrated in FIGS. 12 and 13, the sling 109 shown in FIG. 14, and the sling 110 of FIG. 15.

Referring to FIGS. 12. and 13, the sling 108 comprises an elongated substantially rectangular body made of canvas or any other suitable material.

A pair of J-shaped books 111 having buckle portions 112 integrally formed thereon, are fixedly secured to one end 113 of the sling 108 by means of straps 114 passed through the buckles 112, the straps 114 being sewn to the sling 108 by stitches 115.

The material at the other end 116 of the sling 108 is reverted and a series of spaced transverse stitchees 117, 118 and 119 are extended through the doubled material to form a plurality of channels 120, 121 and 122 therein.

Referring now to FIG. 14, the sling 109 comprises an elongated body of material having one end 124 provided with a pair of J-shaped hooks 125. These hooks 125 have a connecting bar 126 extending therebetween. The material of the sling 109 at the end 124 is passed over the connecting bar 126 and then reverted under the bar 126, after which the double thickness of material is stitched as at 127 to secure the sling 109 to the connecting bar 126. The other end 128 of the sling 109 is also reverted and by extending a series of spaced transverse stitches 129 across the doubled material a plurality of channels 130 are formed as in the sling 108 heretofore referred to.

In FIG. 15, the sling member 110 may comprise a conventional pelvic belt having a loop 132 secured to one side thereof for attachment to a traction cord (not shown), a plurality of grommets 133 for anchoring the same, and straps 134 on each end thereof for attachment thereof about the waist of the patient. The belt .110 may be used in conjunction with the subject hoist whereby traction, pulling or stretching of the patients low back or pelvic spine may be efiected without having to drag the patient on the bed sheets.

In preparing the hoist for operation, the sling 108 is passed under the body of the patient (not shown), after which the lever unit 45 is raised to an upright position. The roller 54 is then detached from in between the side arms 46 and 47 of the lever unit 45 and passed through a selected one of the channels 120, 121 or 122 of the sling. The length of the sling 108 will be varied according to the selection of a particular channel. Next, the sling 108 is trained over the railing 40 of the side rail 26 and the roller 54 is then replaced between the side arms 46 and 47 by inserting the pins 57 in a selected pair of the apertures 63 in the side arms 46 and 47. Here again, the lengthwise adjustment of the sling may be varied according to the selection of the respective apertures 63 in the side arms 46 and 47. Finally, the hooks 111 are engaged over the cross bar 29 of the side rail 25 in the manner illustrated in FIG. 1.

After the foregoing steps have been completed, the hoist is ready for operation. The patient can then be lifted by pivoting the lever unit 45 from its upright position in a downwardly direction, which will cause the sling 108 to move upwardly between the side rails 25 and 26 and efiect a raising of the patient. It the patient is to be kept in a raised position for an extended length of time, the strap 53 may be attached to the bed rail 21 to prevent the release of the lever unit 45.
