Patented June 9, 1942 UNHTED STT 4 Claims.

The present invention relates to beds, and particularly to such as are intended for use inhospitals and the like, and an object of the invention is to generally improve the construction and operation of devices of this class.

More specifically, an object of the invention is to provide a bed adapted to facilitate the use of the bed-pan.

Other objects are to provide for the use of the pan with the least possible discomfort to the patient; to give the patient a sense of security during the use of the pan, thereby encouraging this function; to minimize the accidental soiling of the bed linen, and to lessen the work connect ed with tending the patient.

More particularly, an object of the invention is to provide a bed structure which is in effect divided transversely near the middle so that a difference in the level, or stepped configuration may be established whereby the bed-pan may be readily inserted in the space beneath the patient, and with the least possible inconvenience and discomfort to him.

Certain other adjustments may be made to increase the comfort of the patient during normal occupancy of the bed or when the bed-pan is not being used.

Further objects and advantages of the invention will be apparent from the following specification and accompanying drawings, in which:

Fig. 8 is a detail of a modified pivot construction applicable to the embodiments of Figs. 6, '7, and 3,

Similar reference characters have been applied to the same parts throughout the drawings and specification.

In the embodiment of Fig. 1, the bed includes a bedstead or outer portion including rails l and 2,

connected by a head board 3 and a foot board 4, the whole being supported on posts 5, 6, 1 and 8, and serving to support the spring frames. In this embodiment there arev two independent framesections or portions, generally designated as 9 and Ill, on which may be supported mattress portions II and i2, respectively (Fig. 2), the parts being movable from a contiguous position, forming the usual flat surface, to a relatively displaced position giving a stepped arrangement or configuration, as shown in Fig. 2.

Various arrangements are contemplated for obtaining this movement and relation of parts, and nothing in this specification is to be taken as limiting the invention to the construction illustrated or in fact in any manner except as defined in the claims.

For moving section 9 it is supported, in the present instance, through a plurality of jack elements generally designated as l3, l4, I5, and I6. These units being alike, it will be necessary to describe only one. A sleeve 11 is fixed in a substantially vertical position in a corner of frame portion 9, depending therefrom and interiorly threaded to receive a screw l8. The screw has fixed therewith a sprocket l9 and projects downwardly through a strap or cross-member 20 carried by side rails l and 2, a suitable thrust washer or bearing 2! being interposed. Screw l8'may have a square or other suitable shank portion 22 depending below cross-member 20 on which may be engaged a crank or other control means 23. Sprocket I9 is connected by a chain 24 with similar sprockets 25, 26, 21 associated respectively with jacks I3, l4 and i5. Rotation of screw l8 as by crank 23 will accordingly cause simultaneous operation of all four jacks and bodily raising or lowering of frame section 9. In like manner crank 23 may be applied to any of the other jacks that may be more conveniently accessible.

Raising of sectionll (which is the head section) relatively to section [0 raises the patient bodily with the exception of the feet, leaving a space beneath the legs into which the bed-pan may be readily inserted. The patient may then be shifted slightly toward the foot of the bed onto the pan with very little effort or inconvenience. When the patient is in position it will be noted that the hips are not elevated with respect to the rest of the body, thus giving .a feeling of security and also minimizing the danger of accidents and soiled linen, a very common occurrence in the ordinary use of the pan, since with the hips elevated there is danger of urine running up the patients back.

Obviously the operation may be reversed when the pan is to be removed, and the bed restored to normal condition by lowering section 9 to the level of section I8.

Section ID, if desired, may be lowered to give a still further relative displacement between the sections, being hinged, for example, on a rod 28 extending across from rail I to rail 2 at the foot of the bed.

Near the middle of the bed racks 29 and 38 may be pivoted or otherwise suitably connected with the sides of section I8 as at 3|, and may engage pinions 32 and 33 fixed on a shaft 34 journaled in rails and 2, guides or the like as 35 being arranged to maintain the racks in mesh with the pinions. Shaft 34 may have a ratchet wheel 36 thereon controlled by a pawl 3'! pivoted at 38 to rail and a hand wheel 39 or other suitable means may be provided for turning the shaft to raise and lower the racks and accordingly section It), the adjustment being maintained by engagement of pawl 31 with ratchet wheel 36.

Other means is contemplated for controlling section It]. For this purpose as seen in Fig. 8 section l has a rod 39 carrying rollers as 48 resting on ribs or runways as 4| carried on side rails whereby to provide for longitudinal displacement of the section as well as pivotal movement about rod 39 The inner end of section I8 as seen in Fig. 6 is provided with pins or the like as 42 engaged in the slots 43 of cams such as 44 fixed on a cross shaft 45, the slots being so shaped (for example L-shaped) as to tend to support section l0 in its up position without any appreciable tendency to rotate shaft 45. Initial clockwise rotation of shaft 45 causes bodily movement of section Ill away from section 9, whereby to materially separate the abutting surfaces of mattress sections H and I2 after which continued rotation causes a dropping movement similar to that caused by the above described racks 29 and 38, and as indicated in Fig. 7. In the reverse movement of the shaft, section l0 is first raised, continued rotation of the shaft forcing section I8 toward section 9 and pressing the sections of the mattress firmly together. In this manner the separable sections of the bed are tightly joined for normal use and there is no suggestion of a crack between the sections to annoy the patient.

Suitable or well-known means such for example as above described hand wheel 39 and .ratchet 36 may be applied to shaft 45 for turning and controlling it.

A variation of the basic idea is shown in Fig. 3, in which a bed-stead, having side rails such as 46, and head and foot boards 41 and 48, respectively, has a spring frame including a head section 49 which may be pivoted to the side rails as 'at 58, a stationary section 5| being fixed to the rails and having a movable intermediate section 52 pivoted thereto at 53.

It is contemplated that sections 49 and 5| may be combined in a single immovable section, if desired.

Section 52 has pivoted thereto at 54 a foot section 55 which is carried at the foot of the bed by rollers as 56 carried on a rod or the like 51, the rollers running on ribs or the like 58 carried on the side rails, all as in the manner described in connection with Fig. 8. It will be understood that the frame portions shown in section are rectangular and .that the pivots etc. are duplicated on the side of the bed that has been removed in the sectional view.

A flexible mattress is contemplated for use on this bed construction, although there is nothing to prevent the use of a mattress of two or more pieces, which would be conveniently divided at one or more of the pivotal points.

In this arrangement the several pivoted sections of the frame may be disposed in a common plane for the ordinary uses of the bed, but, for the use of the bed-pan, movable section 52 may be dropped about pivot point 53, carrying foot section 55 downwardly into a slanting position as shown in Fig. 5, thus providing the stepped configuration in the middle of the bed common to the other embodiments for accommodating the receptacle.

Various mechanisms are contemplated for controlling this movement, in the present illustrative embodiment a plurality of members 59 and 68 being arranged to form a toggle, member 59 being pivoted to section 52 at 6| and to member 68 at 62, member 68 being fixed with a cross shaft 63 extended through the side rails and having a lever 64 or other suitable control element within convenient reach of an attendant. In Fig. 3 the toggle is shown as broken, and section 52 as part way down. Continued clockwise movement of shaft 63 will continue the downward movement of the section to the position shown in Fig. 5, as will be understood.

Movement of lever 64 in a counterclockwise direction will obviously cause a straightening of the toggle, raising section 52 into line with section 5|, the parts finally taking the position shown in Fig. 4, with section 52 in the plane of sections 5| and 55. It will be noted that the toggle parts 59 and 68 have passed slightly beyond the position wherein pivots 6| and 62 and shaft 63 are in alignment, so that the weight on the bed will tend to cause further upward movement of pivot 62, and this is prevented by a stop portion 65, in the present instance contacting the under side of member 68, although other dispositions of the stop means are contemplated as within the scope of the invention. The linkage is accordingly self-locking, and constitutes a very simple and positive means of holding the bed parts in normal position.

Head section 49 may be raised about pivot 58 if desired, a bail, link, or similar element 66 being pivoted to the section at 61 and having its lower portion pivoted to a nut 68 engaged on a screw 69 journaled in suitable bearings 18 and 1|, bearing 10 being carried by a cross member 12, forming, conveniently, part of head board 41, and bearing being fixed with a cross member 13 fixed with the rails as at 14. A crank or the like 15 may be formed or fixed on the screw 69 for turning it, whereupon the head will be raised or lowered as desired. This adjustment may give a degree of comfort to the patient in con nection with the use of the bed-pan, or it may obviously be used alone when the other parts of the bed frame are in a single plane, as shown in Fig. 4.
