Bronx, N. Y., assignors to Geriatric Utility Bed Corporation, Mount Vernon, N. Y., a corporation of New York Application `lune 27, 1952, Serial No. 295,998 11 Claims. (Cl. 5-65) Our invention relates to improvements in beds for invalids which are especially adapted for use in hospitals, sick rooms and nurseries.

Our yobject is to provide a simple sanitary structure which is designed for the comfort -of the patients and which lessens the work `of those who care for them.

We have retained the feature shown in our copending applications for U. S. patents, Serial Numbers 86,944 and 165,322, tiled respectively `on April 12, 1949, and May 3l, 1950, of stretching a removable sheet of textile material on a frame to form a support for the patient and have invented certain cooperative features which are disclosed and claimed herein.

Referring to the drawings:

Fig. ll is la plan view of a bed which is made according to and embodies our invention. Certain parts are broken away to show the construction more clearly.

Fig. `2 is aside elevation of the bed yshown in Fig. 1.

Fig. 3 is an end elevation of the bed shown in the preceding figures with some of its parts shown in diiferent relative positions.

Fig. 4 is a sectional end elevation on a larger scale taken on the 4line 4 4 of Fig. l, of some of the parts shown in the preceding `figures illustrating the initial step in Vassembling the parts.

Fig. 5 is a similar View of the assembled parts in different relative positions. In this figure a blanket is shown which is not illustrated in the other figures.

Fig. 6 is a similar `sectional view of the parts in other relative positions.

Fig. 7 is a sectional end elevation `of some of the parts shown in Figs. l, 5 and 6 in other relative positions.

Fig. 8 is an end elevation, partly in section and on a still larger scale, of operating gearing which forms part of the structure. This section is taken on the line V8--8 of Fig. l.

Fig. 9 is asectional side elevation of some of the gearing shown in Fig. 8. This section is taken on the line 9-9 of the latter ligure.

The frame of the bed comprises four vertical posts, 10A, 10B, 10C and 10D. The posts 10A and 10B are interconnected by horizontally spaced transverse bars 11, 11A and 11B. The posts 10C and 10D are interconnected by horizontally spaced

transverse bars

12, 12A and 12B.

Longitudinal bars

13 and 13A `interconnect the posts 10A and 10D and -the

posts

10B and 10C, respectively. These parts are preferably of square tubing and `together form a rigid yframe upon `which the other parts of the structureare supported.

Gear casings

20 and 20A are aiiixed to the posts 10A and 1GB respectively. These `form bearings fora shaft 21 to which are -aiiixedright-and left

hand worm gears

22 and 22A within the casings 2l) `and 20A. A crank arm 23 is affixed to `one end of the shaft 21. From it `ahan dle 24 extends in a direction `parallel to the shaft 21. A gear 25 meshes with lthe worm 4gear 22 and a gear 25A meshes with worm gear 22A. The

gears

25 and 25A are atxed to

stub shafts

26 and 26A which are rotatively mounted in rthe posts 10A and 10B above the

bars

13 and 13A.

Longitudinally disposed -

bars

14 and 15 of square cross section are aixed toand rotate with

fthe shafts

26 and 26A. The 4opposite ends of these longitudinal `:bars 14 and are provided with

pintles

16 and 16A which rotatively support them in the posts 10D and 10C respectively.

A .spaced series of studs 17 project from one side Vof the

bars

14 and 15 and also from the transverse bars 11A .and 12A. iOther .st-uds 17A project from a side of the central partof the

bars

13 and 13A. A series of spaced hooks 18 project from a side of the

rotatable bars

14 and 15 adjacent the sides from which the studs 17 project.

30 isa sheet of rubber or the like to the under side of which are ai'lxed a spaced series of transverse straps 31 having holes near the ends thereof. When the

bars

14 and 15 are in the positions `shown in Figs. 4 and 46, the hooks 18 are passed through the holes in the straps 31. The sheet 30 thereby becomes suspended loosely between the

bars

14 and 15. While in this position -two

mattress sections

32, 33 of foam rubber or like material of substantial lateral rigidity are pushed onto the sheet 30 from an `end of the bed. `These are enclosed in water proof covers 32A, 33A.

Now, by rotating lthe shaft 21 in a direction to rotate the bar 14 as shown in Fig. 4- in a counterclockwise direction, ,and `the bar 15 in a clockwise direction to the posit-ions shown in Fig. 5, the straps 31 will be tightened and the mattress .members raised to a horizontal position. Thestuds 17 on the

bars

14 and 15 will then project outwardly.

40 `is ,a sheet of rayon .or `the 4like which has reinforced button-holes near its edges, spaced to register with the studs 17 on the

bars

14, 15 and 11A, 12A. The sheet is attached to the frame by passing the studs through `the buttonholes.

An orifice 41 is `formed in the central part of the sheet 4.0. When not in use this orifice is closed by a `narrow auxiliary `sheet `42. Button-holes are provided near one of its -edges through which a few of the studs on bar 14 arepassed `before these studs are passed through the button-holes `in sheet40. Straps 43 extend from the opposite edge of the auxiliary sheet. These `straps are passed through openings 44 in lsheet 40, thence over bar 15 to the studs projecting therefrom to Which they are aixed in the lmanner `described previously.

This arrangement is such that although the auxiliary sheet 42 is under the main sheet14il, it may be removed without disturbing a patient lying on the main sheet.

By reversing the previously `described rotation of` the bars 14 and 1S, the parts will be brought into the posi-v tions in which they are shown in Fig. 6. The mattress sections will be lowered and the sheet 40 brought into tension `sufficient to support the patient.

50 indicates a position into which a bed pan supported by the

mattress sections

32, 33 may be moved under the orifice 41. Intermediate positions of the sheet 40 and mattress section 33 are shown in Fig. 7. In either the Fig. 6 -or the Fig. 7 positions of the parts, the patient may use the bed pan in comfort and with a minimum of soiling.

In either the Fig. 6 orthe Fig. 7 positions ,of the parts (preferably vthe latter.) the patient or an infant 'may be bathed. In Figs. 2 and 3, the position ,of a water receptacle is indicated at till. This is 4supported upon a comparatively .narrow vsheet :61 provided on opposite edges with button-.holes ithrough which pass studs 17A which project from Vthe longitudinal bars 1.3 and 13A. An orifice y311A is provided .in the sheet 30 under the orifice r41.

In Fig. 5, the position of a body ,is .indicated at 70. Over it is spread a blanket 71. designated a strip :of nylon or the like, apart 73 ,of `which `is stitched to three sides `of the blanket .corresponding to the sides and foot of the pa-tient, Ain positions spaced from these edges .of the blanket. A free part 74 is provided with buttonholes through which the studs 17 projecting from the

longitudinal bars

14 and 15 may be passed.

A similar part (not shown) is provided to receive the studs projecting from the transverse bar 12A.

When the blanket is thus connected to the bed frame it cannot become displaced, neither can a patient covered by the blanket roll out of bed. This blanket or other suitable covering material when properly modified may be used as a form of restraint for disturbed patients.
