'2 Claims.

The invention relates to hospital beds, and has for its object to provide a device yof this kind comprising a head section connected to a foot section by an intermediate section, and means whereby the head section may be elevated with a patient on the same, toa position where the intermediate section will extend upwardly, thereby allowing a bed pan to .be placed beneath the patient in a position for use, .and at the `same time o'bviating the labor involved in lifting. patients, now experienced with conventional hospital beds.

A further objectl is to provide meanswhereby the head section may be adjusted to various angles, and independent means whereby the toot section may be .adjusted to various angles.

A further object is to provide the side rails. of the bed with plates, andto connect the .foot end of the intermediate section pivotally thereto and to provide elevating and adjusting. meansfor the various sections and cooperating with the bed rails for the elevating operation.

A further object is to provide downwardly offset transverse braces for the intermediate section connected together by longitudinally vextending bars and operating means connected to one of said braces for hingedly moving the intermediate -seotion on its hinged connection to the plates carried by the side rails of the bed.

A further object is to provide means whereby the head section may be raised in a horizontal plane through a link connection including the intermediate section 'and means. whereby' said head section may be inclined at. various angles after an elevating operation.

A further object is to provide an. adjustable hospital bed having a head section whichmay be elevated for elevating the body of .a patient land allowingT a bed pan to be easily and quickly placed under the buttocks without. the necessity of manually lifting the patient,and at the same time facilitating the .cleaning operation of the patient after the use of the bed pan,

With the above and other objects .in View the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment oi the invention may be made without departing from the spirit of the invention.

In the drawings:

Figure 2 is a top plan view of the bed.

Figure 3 is a vertical transverse sectional View taken on line 3?--3 of Figure l.

Figure 4 is a vertical transverse sectionalview taken on line fl--Jl of Figure l.

Figure 5 is a vertical longitudinal. sectional view through the bed, showing the head section elevated.

Figure 6 is a longitudinal sectional View through .the extensible connection of one of the operating shafts.

Figure l is a side elevation of a modified form of bed showing the head section elevated.

Figure 8 is a perspective View of the form shown in Figure '7.

Figure 9 is a top plan View of the form shown in Figure 7.

Referring to the drawings, and particularly to Figuresl l to 6 inclusive, the numeral l `designates the head frame of the bed and 2 the foot. The head and foot of the bed are connected together by side rails 3 for forming a rigid structure. Secured to the outer sides of the side rails 3 by means oi rivets il are upwardly extending plates 5. Disposed above the side rails t, preferably in registry therewith are the head section t, the intermediate section l and the foot section 8 of the adjustable parts of the bed. The foot section may be formed in two sections, hingedly connected `at 9, if desiired, so that a leg adjustment may be obtained. The foot end of the intermediate section i is hingedly connected at lll to one of the ends of the plates 5, and adapted to be hingedly moved upwardly to the dotted line position shown in `rfigure l, and the full line position in Figure 5 for elevating the section 6, hingedly connected at ll to the end of the section 1 The opposite sides of the intermediate section l are connected together by downwardly arched transverse braces i2, one of which forms the ,pivotal point lil, and these braces in turn further braced by longitudinally extending braces i3. Connected to one of the braces l2 at Hl is an operating shaft l5 which extends to the foot 2 of the bed and has an extensible connection l 6 therein. The extensible connection i6 includes a threaded member carried by the shaft section ld. and this threaded member is designated by the numeral ll. When the shaft o is rotated a push or pull is imparted to the shaft l5 for raising or lowering the intermediate section l. Shaft lila is rotatably mounted in a rock sleeve bearing lf pivotally mounted at lil in a bracket 2i! carried by the foot 2 of the bed, and terminates in a crank 2l adapted to be grasped by the operator for raising or lowering the intermediate section l.

The head section which hingedly connected at ll to the intermediate section 'l is raised or lowered to the proper elevation by means of I rollers 22 engaging the under side of the frame extends to the foot 2 of the bed and terminates in an operating crank 30. Shaft 29 is provided with an extensible connection 3|, similar in construction to the connection I6, therefore it will be seen that by operating cranks 2| and 30 the intermediate and head sections I and 6 can be easily and quickly adjusted upwardly or downwardly and that the body of the patient can be raised so a bed pan can be placed under the buttocks. l

A conventional form of mattress 32 rests on the bed sections 6, 'l and 8, and it will be seen that this mattress will conform to the adjustment of the various sections, clearly shown in Figure 5, and at the same time, with the body of the patient resting on the portion of the mattress carried by the adjustable section 6, the mattress will not become displaced during the body elevating or lowering operation.

After the sections have been properly adjusted as shown in Figure 5, the bed pan 33 is placed under the buttocks 34 of the patientwith the extension 35 of the bed pan extending upwardly above the buttocks and in close engagement with the mattress 32. It will be seen, during the elevating operation, that the Weight of body is lifted mechanically, and it will not be necessary for the nurse to lift the body as is now the common practice when a pan is used.

It will be noted that the foot section 8 has hingedly connected thereto at 9 a second foot section 8a, and these sections may be adjusted upwardly by means of a U-shaped frame 34a having arms 35a extendingtowards the foot 2 of the bed and pivotally connected onthe hinging points 9. Where the U-shaped bracket 34a merges into the arms 35a rollers 36 are provided which have a trackway on the upper sides of the side rails 3 of the bed, and it will be seen that when the U-shaped bracket 34a, Figure 5, is moved in the direction of the arrow a. the hingedly connected portion of the foot sections 8 and 8a will be moved upwardly, therefore it will be seen that a leg adjustment may be obtained when desired. The U-shaped bracket `34a, is operated by means of a shaft 3l having an extensible connection therein, designated by the numeral 38 and similar in connection to the connection I6. Shaft 31 term.-

minates in a crank 39 at the foot of the bed. It

will be noted that the adjustable sections 6, `1 and 8 are in registry with the side rails 3 of the bed, therefore it will be seen that it will not be necessary to materially vary the construction of a conventional form of hospital bed when applying the device thereto.

Referring to the modified form shown in Figures 7 to 9 inclusive, the foot section 40 may be rigidly mounted in a frame 4| which rests on the bed rails 3 and said frame may be connected to the bed rails 3 by means of plates 42, however applicant does not limit himself in this particular. An intermediate section 43 is hingedly connected at 44 to the foot section 40 y and has hingedly connected thereto at 45 a head for extending the extensible member I carried by the shaft 52. The shaftA 52 is pivotally connected at 53 to a, cross bar 54 carried by the downwardly curved arms 55, connected by welding or otherwise to the intermediate section 43 adjacent its hinging point. As the intermediate section 43 is hinged upwardly the l links 46, which are the length of the intermediate section, will cause the head section 45 to move upwardly, maintaining a horizontal position. At times, it is desirable to further elevate or incline the head section 45a, and to accomplish this result, the operator rotates the crank 56 which extends the extensible connection 51 and imparts a movement in the direction of the arrow b, Figure 8, to the shaft 58, and this shaft is pivotallyv connected-at 59 to the cross bar Ell the ends of which are connected to the pivoted levers 6I, pivotally connected at 82 to the frame 4l and terminate in rollers 62a which'engage the under sides of the side arms 48 of the auxiliary frame 4l, therefore it will be seen that the head section can be easily and quickly adjusted to various angular positions or left in a horizontal-position for bed pan use.

It will be noted, in the form shown in Figure 5, that the head section can be inclined downwardly towards the head I of the bed,v and this is particularly desirable where encinas are used, so the patient will retain the enema.

From the above it will be seen that a hospital bed is provided which is simple in construction and one wherein the body of the patient may be mechanically elevated when it is desired to use a bed pan, administer enemas or for other purposes, and at the same time the nurse is relieved of the necessity of lifting the patient, as is now the common practice. The intermediate section, when inclined upwardly, may be adjusted at an angle for the reception of the special bed pan, held in position by the weight of the body of the patient. This bed pan forms the subject matter of a separate application, Serial No. 396,922, filed June 6, 1941, which became Patent No. 2,359,830 on Oct. 10, 1944.

The invention having been set forth what is claimed as new and useful is:

l. The combination with a bed comprising a stationary main frame, a foot section anchored to the main frame, a head section, an intermediate section, said sections being hingedly connected to each other at their adjacent ends, means for hingedly moving the intermediate section upwardly or downwardly on its hinged connection to the foot section', of means for raising the outer end of the head section, said means comprising a hinged auxiliary frame below the head section and hingedly connected to the main frame, link connections between the auxiliary frame and the free end of the head section whereby a parallel movement is formed in connection with the intermediate section when the intermediate section is upwardly hinged, means for upwardly hinging the intermediate section, and means cooperating with the auxiliary frame for raising the same whereby the head section may be adjusted to various angular positions.

2. A device as set forth in claim 1 wherein the intermediate section and the link connections between the auxiliary frame and the free end of the head section are the same length between their hinging points.
