Filed March I5, 1967 United States Patent 3,383,717 BED DEVICE FOR MOVING PATIENTS Raymond Underwood, Cleveland, Tex., assignor of one-half to Opal M. Underwood, Cleveland, Tex. Filed Mar. 3, 1967, Ser. No. 620,393 4 Claims. (Cl. 61)

ABSTRACT OF THE DISCLOSURE This application describes a bed attachment for care of bedridden persons and is based upon a construction which adjusta'bly secures an angle iron to each of the four corner posts of a bed. Other adjustable tie members and shafts mounted on the angle irons convert the angle irons into a rigid structure which may support the patient independently of the spring and bed frame. Shafts which extend one on each side of the bed are rotatable and can hold bed sheets therebetween on which the bed occupant may be lifted or turned by appropriate rotation of the shafts. A similar head or foot end shaft may move the bed occupant longitudinally.

This invention relates to a bed attachment which facilitates moving, lifting and otherwise caring for bedridden persons like invalids or patients. More particularly this invention relates to an attachment adapted for use with beds having a head-board, or a footboard or both.

It is an object of this invention to provide a patient lifting and moving structure which may be detachably connected to most beds without requiring structural modification of the bed.

It is another object of the invention to provide a bed attachment which permits shifting the patient about in the bed as from one side to the other, or from back to side, and which also permits raising the patient above the mattress level to permit bed linen to be changed readily.

Still another object of the invention is to provide a patient moving and lifting attachment for beds which includes an improved means for securing thereto the sheet on which the patient rests.

Still a further object of the invention is to provide means for securing a split sheet to the moving and lifting attachment.

In achievement of these objectives the present patient moving and lifting attachment includes four angle iron members, one for each of the four corner supports of a bed. The angle members are constructed with arcuate cutout recesses which serve to support therein a pair of parallel shafts extending longitudinally, one at each bed side. The opposed longitudinal side edges of the bed sheet are secured to each of the parallel shafts by a rod disposed in a hollowed out slot on the shaft surface. Crank members received in shaped openings at the shaft ends may selectively rotate the shaft members to lift one or both longitudinal side edges of the sheet, causing the patient to be turned or lifted appropriately.

In addition, the angle members at each post have mounted thereon support brackets which receive and rotatably support a shaft transversely extending across the head or foot of the bed. This transversely extending shaft may have secured thereto an auxiliary sheet so that rotation of the transverse shaft may serve to shift the patient longitudinally of the bed.

An important advantage of the present structure is that all the components of the present accessory structure are mounted only on the four angle members, including any bracing elements needed to form a rigid structure. Other advantages of the present invention will become apparent 3,383,717 Patented May 21, 1968 "ice from the more detailed following description taken in conjunction with the accompanying drawings in which:

FlGURES 7, 8 and 9 are fragmentary perspective views of the rods and locking devices for rolling the sheets on; and

FIGURE 10 is a section through FIGURE 9.

Referring now to the drawing and more particularly to FIGURE 1, there is shown ahospital type bed 10 having a head end member 14 and afoot end member 16. At each corner of the bed is mounted anangle iron 18 formed with a plurality of spaced apartcutouts 22 on oneflange 20. Theother flange 24 ofangle 18 is essentially blank, being provided only with some drilled holes for attaching certain component elements ontoangle iron 18. As shown in the drawing theangle irons 18 are mounted on the four corner posts with aperturedflanges 20 face to face lengthwise ofbed 10 andblank flanges 24 face to face across the foot end and head end ofbed 10.

Angle irons 18 are secured without damage to the bed structure, by boltingfiat tie pieces 28 to the back face of the aperturedflange 20. Thesetie pieces 28 extend inside head end 14 andfoot end 16 ofbed 10 as is shown in the drawing. For greater stability a pair oftie pieces 28 are provided at both head and foot ofbed 10 with the lower tie pieces resting onside frame member 26. Cooperating withtie pieces 28 areangle pieces 30 each of which is bolted at itsslotted leg 32 to the back face of a flange 24-. Theother leg 34 ofangle 30 extends parallel totie pieces 28, being spaced therefrom a distance equal to width of the head end member 14 orfoot end member 16 as the case may be. The actual distance betweentie piece 28 andangle 30 is determined by the adjustment of the angle piece in its slot attachment toflange 24. In consequence head end member 14 andfoot end member 16 are securely clamped between the flat faces ofangle piece leg 34 andtie piece 28. To avoid marring or disfiguring the headboard and foot-board aplastic bumper 36 may be wrapped around theangle leg 34 and a similar bumper around thetie piece 28. Reinforcing rigidity for the four associatedangle irons 18 may be provided by mountingrail 40 on the blank face offlanges 24 across the top of the head end member 14 andfoot end member 16 as is shown in the drawings.

Since bed It) and its component parts like headboard 14 andfootboard 16 come in varying sizes, an important aspect of the present structure resides in its provision for substantial adjustment to fit different bed sizes. An adjustment is provided for bed width in the length oftie pieces 28 by formingtie pieces 28 as an adjustable composite structure of two tie piece segments 27 and 29. One tie segment e.g. 27 is slotted near its juncture with the other tie segment 29 (suitably by a four inch slot) and the other tie segment 29 is provided with a multiplicity of bolt holes (e.g. two). The variable over-lap provided by the slot-bolt hole connection provides an adjustment of several inches which is adequate for the usual variation in width bed-to-bed. Inlike fashion rails 40 may be adjustable-length composite members joined e.g. bycouplings 42 as is shown in the drawing.

It may be seen in the drawing howflange 24 ofangle irons 18 face each other across the foot and the head end of the beds, while flanges 2% face each other longitudinally of the bed with cut-outarcuate slots 22 opposed so that a pair of longitudinally extendingshafts 44 may be removably mounted for rotation onangle irons 18 in the arcuate portions of cut-out 22 of flanges 29. Additional flexibility is provided by presence of the multiple cut-outs 22, three being illustrated on each angle iron.

The detailed construction ofsiaft 44 and its mounting for rotation .in the flange arcuate portion 45 is shown in FIGURES 4 and 5. A circular rotatable bearing (e.g. nylon) rests on the flange material at arcuate portion 46. In turn, bearing 5%) is held in predetermined position longitudinally ofshaft 44 by a pair of flangedretainer rings 52 whose opposed flanges 5 2- serve to further retainshaft 44 longitudinally in position relative to the flanges 20'.Rings 52 are held ontoshaft 44 by set screws or some other fashion which permits releasable engagement and longitudinal movement on theshaft 44. Freedom of movement longitudinally of the shaft is important since it permits theshaft 44 to be relatively oversized so that it might fit varying bed sizes. Adjustment of retainingrings 52 onshaft 44 and therewith bearing 50 permits a perfect lit for each bed.

As may be seen also in the drawing theretainer ring flanges 54 are provided with a plurality of spaced apart circular apertures 56 (FIGURE 3).Apertures 56 are sized to fit alocking pin 58 and with locking pin 53 in place inopposed apertures 56, the shaft assembly as a whole can no longer rotate in arcuate portion 46.

The ends ofshaft 44 are each provided with a.square key slot 60 so that a crank 62. may be inserted therein to rotateshaft 44.

As may be seen also from FIGURES 7, 8, 9 and an elongated recess orslot 64 is provided in the outer surface of theshaft 44 androd 66 is disposed therein.Rod 66 may extend the entire length ofshaft 44 or as a preferred alternative is a split rod with two half-sized rods 67 and 69 resting inrecess 54. Adjacent each terminal end ofshaft 44 is alocking ring 68 containing a threaded opening adapted for a set screw which then serves to lockring 68 ontoshaft 44 and at the same time also to lock rod 66 (or alternativelyhalf rod 67 and 69) inrecess 64.

For moving a patient longitudinally of the bed, a transversely disposedshaft 44, constructed likelongitudinal shafts 44, is mounted for rotation in bearing supports 70 (shown in FIGURE 6) on the flanges at one end ofbed 10, with a rotatablecircular bearing 72 resting on the material of supports 70 (shown in FIGURE 7). If desired retainer rings 52 may also be provided to fix the position of bearing 72 on transverserotatable shaft 44. FIGURE 1 illustrates crank 62 mounted intransverse shaft 44 for rotation thereof causing longitudinal movement of the attached sheet. 76 serves a purpose similar toring 68.

It can be seen from the foregoing that there is provided in accordance with this invention an attachment for hospital beds and the like which may be easily attached to a hospital bed, and, in fact, to almost any bed having posts at the four corners thereof. The attachment of the invention permits the sheet or the like underlying the patient to be wound onto one of the longitudinal shafts to move the patient from side to side or from his back to his side, and also permits the sheet or other flexible member to be entirely raised above the level of the mattress to permit changing of the underlying linens on the bed. The attachment mechanism also includes means for shifting the patient longitudinally along the bed. It can be seen, therefore, that the structure hereinbefore described has great utility and practical value.

While there has been shown and described a particular embodiment of the invention, it will be obvious to those skilled in the art that various changes and modifications may be made therein without departing from the invention, and, therefore, it is aimed to cover all such changes and modifications as fall within the true spirit and scope of the invention.
