ADJUSTABLE-REST FOR nEnsrEAns.

1 My invention relates to adjustable rests for bedsteads and is of. particular value in connection with back rests employed .on hospital beds equippedwith resilient 'bed bottoms.

The principal objects of the invention are to provide an adjustable rest. which can be conveniently applied to an ordinary bed bottom without extensive reconstruction of the frame or other-parts; to provide a rest' which will partake of the same general movement as the surface of the bed bottom itself; to provide abackrest which, when not .inuse, will not materially interferewith the normal action of the bed bottom or with the bedclothing; to provide a construction which shall be simple and economical to design and manufacture and in general to provide a neat, convenient, substantial and eflicient rest of the character referred to.

In the drawings which illustrate my invention asappliedv to a bedstead of what, in the trade, is known. as the three piece yp Fig.. 1 is an elevation of the bedstead showing the back restin elevated position; Fig. 2 is a sectiontaken on the, 1ine2 2 ofFig.1;

Fig. 3-is a sectiontaken on ofF1g. 1;and I Fig. 4 is a View similar to Fig. 1, but showing the back rest in depressed position.

' Referring to the drawings, and 1-1'jrep' {resent respectivelythe head and foot end frames of the bedstead to which by means of suitable corner fastenings, as at 12 the combined bed bottom and connecting frame 13 is detachably; connected. Said corner fastenings 12- are fully. set forth and described in the U. S. patent to Busch, dated Nov. 15, 1921, No. 1,397,203. a

1 The tubular stretcher bars or side rails 14 are located at some distance below the bed bottom-supporting surface in order to permit same to be depressed when conforming to the'shape of the occupant of the bedstead. Said I supporting surface in the present instance comprises a fabric made upoflong links 15 connected end to end to form longitudinal chains, said chains being: tied together transversely by cross links 16, The

. helicals 18 in the .usual manner and the side edges or side boundaries of the bed fabric are composed of a pair of fiexiblesteelslats 19 also connected to and stretched between thecrossmembers 17 by helicals as at 20. I

In the present instance I have shown my inventlon as applied to a backrest suchas is desirably employed inhospitals in order topermit the patient tov assume a more comfortable position or to sit up in bed when able to do so. Said back rest, comprises a substantially rectangular section of fabric constructed like the main be d fabric of ion gitudinal and cross links suitably; connected together. However, in the case of the back" rest, the chains formed. from the longlinks 15 are stretched transversely acrossthe' arms of a U'shaped frame 21. i V The ends22 of the arms ofthe U -shapedframe: are preferably flattened andperforated'to receive-pivots or rivets 23. Said r vets also extend; through the upper or jvertical flanges 241. of stripsofangle iron,25'

riyetedthrough, the horizontal flanges 26 to the slats oredge members 19 so that said longitudinally extending angle irons move witlrtheside slats, 19 when the latter are depressed. Because helicals 27, by which .pivotal points of. the backrest atthe proper distance apart. t I v :transversestretcher baror tube 28, the in- Said means comprises. a

termediate portion of'whichis; ofiset a sUfiicient distance below the surfacev of the main bed fabricto prevent interference therewith xdue tofthe weight ofthe occupant. .The ends,

of said transverse stretcher bar 28 arerigidly united to the ends of angle irons 25 by the fiattened'to facilitate insertion of said rivets. ln orderto' maintain .the'back rest in its 'Jdesired angular, position of adjustment, I

employ an-adjustable strut framecomprising .-a pair ofzside members as-at 30 pivoted at theirupper. ends to pins 31 on the outer sides of the U-shape d frame 21 and ha-ving their lower ends. connected by means of 'a trans- }versely extendingghorizontal tie rod 32. Said .tie"rid 32 1is=preferablya round-bar ends of the longitudinal chainsare "connectfand is adaptedto cooperate with notches or ed to the end pieces or. cross angles 17 by flange 2 4: oftheangle members 25; Sa d notches33 arev suitable spaced apart soas to serrations 3-3 formed in the upper orvertic'al the transverse chains of :the backrest fabric rivets 29, the ends of. bar 28 being suitably position, the nurse simply lifts'up' on U- shaped frame 21, permitting rod 32 110 ride over the serrations and automatically locking the back rest when the rod 32 drops into the proper notches. To lower the back rest form, its elevated position shown in Fig. l to the position shown in- Fig. 4, or to an intermediate positionthe nurse raises the back rest slightly u-n til rod- 32- canbe disengaged from its notch. Then the strut frame, by meansofon'e of the side members can be swung. up into afsubstantially horizontal position permittingthe back rest to be lowered. Y

' It-wil-l be observed that when the back rest isi-n its operative position, as shown in Fig. 1, the lower edge of the'back rest fabric is substantially in engagement with the upper surface of the main bed fabric, which condition prevails even though the main bedfabric iscon-siderably depressed by the weight of the occupant. This results from the fact that the pivotal point of the back rest'is Supported onthe flexible sla-t member 19, of the movement of the bed fabric; g

The. described'details of construction and operation are merely illustrative of a' single phase ofmy invention, thescope of which should be determinedby reference to the appended claims, said claims being construed as broadly as possible, consistent with the state of the art.
