1 i The present invention relates to a chair which is expressly constructed for use by sick andA bedridden persons, the same `being especially and suitably designed to occupy a satisfactory position atop the mattress, whereby to provide a con, venient chair and support for the occupant of the bed. y

Although the chairv was expressly constructed, at the time of inception,` for use in connection with hospital beds, it is obviously, and equally well ladapted for use in the home, and places of convalescence and recreation Brieliy, the preferred chair is characterized by. a suitable frame which is adapted to t firmly and horizontally on the mattress, this` part of` the structure being provided with conning sides and armrests .and being .expressly designed to accommodate a tiltably adjustable back-rest. More explicitly, the` chair proper comprises a pair of spaced, parallel, horizontal rails to rest upon themattress, uprights connected to and rising from said rails, and auxiliary rails above the mainbase rails, said auxiliary rails constituting side guards and arm rests, and being constructed at their rear ends to appropriately coniine and adjustably support a'back-rest, the latter hingedly connected to the rear end portions of the base rail.

Other objects, features and advantages of the invention will become more readily apparent from the following description and the accompanying illustrative drawing.

In the drawing, wherein like numerals are employed to designate like parts throughout the views:

Figure 1 is a front elevation of a bed chair constructed in accordance with the principles of the present invention showing the same set up and ready for use.

Figure 2 is a side View of same illustrating it positioned on a mattress and also showing the adjustable positions of the back-rest.

Figure 3 is a bottom plan View.

Figure 4 is an enlarged detail section on the line 4-4 of Figure 2 to show the latch construction, certain of the parts being omitted for clear-A ness of illustration.

Figure 5 is an enlarged View showing how the table board is slidably mounted and held in place.

denoted at B. The back-rest is the simplest ofl the two parts in form, and comprises a frame embodying vertical members 6, top and bottom v 4 Claims.

members 'I and 8` and suitablyfiattached andV spaced slats 9. The side members are` mortised, as shown in Figure 4, to accommodate, ineach instance, the projecting portion I0 of a latch plate II. `The latter is screwed orotherwise fastened in place and the part I0 issocketed. toraccom-f. modate a coil spring I2. The spring servestoprol ject the keeper endI3 of the head-equipped latch pin or plunger I4. i The chair A comprisesa pair Iofspaced parallel bottom or base rails I5, these `being adapted to; sit flat on the mattress I6, as shown in Figure .2.l

Inwardly of the rear end is a substantially U- shaped strap II having its outer end portions secured to the top surfaces` ot thenbase'railsJS, the free ends being `upturnedtoprovide accom-L modation ears or lugs I8 to which the hinge Pintles I9, on the back-restB, are connected. This U-strap I'I is the `main means lor" connecting the` rails together.

I now call attention tota plurality of uprights 20, 2| and 22, as seenV in Figurex2,'these hav-` ing their inner,- laterally-directed, lower ends .23A riveted or otherwise secured .to longitudinallyspaced portions ofthe respective baserails 1I5.\

Next, I call attentionfto theupper lor auxiliary chair rails 24. I provide a pair of these disposed in parallelism and of angular form. The horizontal, inturned anges are denoted at 25 and are reinforcing elements as well as ledges. The upper ends of the uprights 20, '2l and 22 are riveted to the vertical anges of said rails 24. As seen in Figure 5, a slide board or suitable plate 26 is provided, it being of general rectangular form, this part serving as a general utility table. Its outer, transverse ends slide on the ledge flanges 25 and said flanges 4have channels 21 formed in their under surfaces. The channels constitute keyways and serve to accommodate the keys or detents 28 carried by the keying cleats 29 bolted or otherwise secured to the under surface of the table board y2li. It will be noted that these flanges 25 stop short of the point occupied by the back-rest B when said back-rest is in perpendicular position, as shown in Figure 2. Thus, the rear or terminal end portions of the rails constitute adapters and are denoted by the numerals 30. The curve slightly down and have their free ends inturned and riveted to a cross-strap 3|. This serves as a rest for the rearmost and inclined position of the back-rest, as shown at the right in Figure 2. It is also to be noted that these downturned end portions 30 are provided with longitudinally spaced apertures which constitute keepers 32 for selective reception oi the ends I3 sits directlyA onl themattress between said,` rails.,y The uprightsandauxiliary side rails constitute;

coniining sides as well as arm rests toaid in supporting'tmpatient. The table 26 comes in handy for reading, eating, and other useful purposes.` The back-rest is lightweight, yet sturdy, and easy to adjust, making it possible for the patient to recline to a position of requisite comfort;

Finally, my improved chair, with backrest and side arms, can be used to advantage as a convenient support for patients that need a sitting position in bed, such as with heart disease. The side arms serve as fa protection against falling sideways when'patients are unconscious orvsemiconscious. I f

It is thought that persons skilled in the art to which the inventionrelates will be able to obtain a clear understanding of the invention after considering the. description in connection with the drawing. Therefore, a more lengthy. description is regarded as unnecessary. Y I
