Filed Apr. 11, 1%1, Ser. No. 102,236

6 Claims. (Cl. -60) This invention relates to invalid furniture, and more particularly to an improved convertible bed-chair device such as may be readily adapted alternatively to either bed or wheelchair use while being occupied by the patient.

A primary object of the invention is to provide an improved device as aforesaid which is convertible with improved facility and without requiring the occupant to be lifted or to step out of the furniture piece.

Another object is to provide an improved device as aforesaid whereby the patient may with utmost ease shift his body between alternative use positions of the device.

Another object is to provide an improved device as aforesaid which is of simple and rugged design and relatively inexpensive to manufacture.

Another object is to provide an improved device as aforesaid which may be operated by the nurse or attendant with improved ease and facility.

Other objects and advantages of the invention will appear from the specification hereinafter and the accompanyingdrawing of an exemplary form of the inven tion wherein:

FIG. 1 is a top perspective view of a device of the invention, shown as being set up for bed use.

FIG. 2 is a corresponding view showing the device arranged for use in chair form.

FIG. 3 is a fragmentary sectional view on enlarged scale, taken along line 3--3 of FIG. 1.

FIG. 4 is a fragmentary sectional view taken along line 4-4 of FIG. 3.

FIG. 5 is a fragmentary sectional view taken along line 55 of FIG. 4.

FIG. 6 is a view corresponding to FIG. 4 but showing adjustment of the device to chair form.

FIG. 7 is a fragmentary sectional view taken along line 7-7 of FIG. 6; and

FIG. 8 is a fragmentary end view of the device as shown in FIG. 2.

As indicated hereinabove, the present invention contemplates provision of a hospital type bed which is readily convertible into wheelchair form; a particular feature being that the patient may either with or without assistance shift his body with maximum ease and natural movements between recumbent and upright sitting positions, thereby utilizing alternatively the bed and chair portions of the device. The mechanical features of the device are such as to facilitate and minimize the assistance required by the patient incidental to the conversion operations.

Thus, as illustrated at FIG. 1 herein the device of the invention comprises a three unit construction including head, center, and foot sections designated generally at It), 12, 14 respectively. Each section comprises essentially a horizontally disposed rectangular frame 16 carrying trmsversely disposed spring slats 18 for support of corresponding mattresses or cushions 20, 22, 24. The frames 16 are supported upon vertical legs 26, the leg devices at the front and foot ends of the bed conveniently comprising portions of the conventional head and foot bed frames. The head and foot frames may include if de sired, transverse bars 28, and all of the legs 26 are provided with wheel castors as indicated at 30.

For bed use the units 10, 12, 14 are maintained in end-to-end aligned interconnection as shown in FIGS. 1 and 3 by means of a tie-rod 32 which slide-fits through 3,138,895- Patented June 30, 1964 guide tubes 34-34 carried by the frames 1616 of at least two of the units; the rear end of the rod 32 being fitted with a hand crank 35 and the leading end of the rod being screw-threaded as indicated at 38 for threading engagement with a bored and tapped block 46 carried by the frame of the third unit. Thus, it will be appreciated that when the three units are disposed in side-byside alignment as shown in FIG. 1, and the tie-rod is slide-fitted through the directionally aligned guides and then rotated by the crank 36, the threaded end of the tie-rod will draw through the block 40 and thereby snug the three bed units together and maintain them in bed-forming arrangement as shown in FIGS. 1 and 3. However, upon withdrawal of the tie-rod, as indicated by broken lines in FIG. 3, the three units will be freed from one another and will be individually self-supporting upon their own leg and castor devices.

It will be seen that the center unit 12 is disposed substantially at the longitudinal center of the device when arranged in bed form, and thus the mattress portion 22 is disposed to support the pelvic portion of the patients body when recumbent upon the bed. Hence, whenever the patient swings his body so as to extend his legs laterally from the bed he naturally swivels his pelvic section upon the cushion 22 and then assumes a sitting position thereon with his legs hanging over the side. In accord with the present invention, the cushion 22 is of two-piece construction and comprises cushion sections 22a and 22b hingedly connected as indicated at 44 (FIGS. 1 and 6), the portion 22a being suitably dimensioned to function as a comfortable seat cushion, while the portion 22b is suitably dimensioned to function as a back rest when tilted to its raised position as shown in FIG. 6. To provide for this alternative positioning of the cushion part 221), a supplemental support frame 46 is provided to hinge upon pins 48 carried by the main frame 16; the frame piece 46 being slotted as indicated at 49 (FIGS. 4, 6) to enable the cushion part 2212 to rise to the position shown in FIG. 6. The pins 48, as well as companion pins 43a, may be arranged to mate with holes found in the next adjacent frames to act as guide devices to accurately position the unit parts in aligned relation.

U-shaped members 50-50 are pivotally mounted as indicated at 52 upon the main frame 16 of the center unit 12 and normally suspend thereunder as shown in solid lines at FIGS/1 and 2. However, when the center unit is separated from the two end units the members 50-59 may then be swung up to arm rest forming positions as shown in broken lines at FIG. 2, and in FIGS. 6, 8; the arm-rests 561-50 and the back-rest frame 46 being then interlocked by means of latch plates 54 which are pivotally carried upon the arm rests as indicated at 56. Thus, it will be appreciated that whenever a recumbent patient desires to sit upright in wheel chair fashion he may be simply swivelled upon the seat cushion portion 22a into upright sitting position, whereupon the tie-rod 32 will be cranked out of connecting relation and withdrawn whereby the center unit is fully separated from the end units which are then rolled aside. The back rest and arm rest devices are then folded upwardly and interlocked to provide complete sitting support for the patients torso. Handle bars as indicated at 58--53 may be provided for the convenience of the patients attendant when wheeling the latter from place to place. Foot-rest devices as indicated at 6G60 are conveniently suspended from the main frame 16 of the unit 12, and are preferably hinged thereto as indicated at 62 and arranged to be held in positional adjustments by means of corresponding ratchet bar devices 64 (FIG. 8).

Although only one form of the invention has been illustrated and described in detail herein, it will be understood that various changes may be made therein without departing from the spirit of the invention or the scope of the appended claims.
