i The present invention relates to attach ments for chairs, couches orbeds, but-is more particularly intended for use with invalid chairs and serves-toprovide a rest for a tra book, newspaper or the like.

ne of the primary objects ofthe-invention resides in the provision of such a support which'may be readily swung into position across'the front of the chair. and which may,

with equal facility be collapsed andswun back into storage position at the side .of-the chair. w

Another object of the invention consists in the provision of a support which may be adjusted to various. heightsa'nd at various angles so as to adapt it to the convenience of the occupant of thechair.

Other objects andadvantages oftheinvensv tion will beapparent from the followlng de-' scription when taken in connection with the accompanying drawings; in which Figure 1 is afragmentary perspectlve View of an invalid chair with the novel attachment placed in operative position for=supporting a book orthelike.

.Figure2 is a similar view wlth the attachment adjusted to position to serve as a-support'for a-lunch' tray;

F igure .3 s a similar, view showlngthe attachment completely collapsed ,and, 11,1 stored position attheside of the chair, and also indicatingin dotted lines the attachment about to be swung into position across; the front of the chair. 7

' Figure 4 is. a detail perspective view of the chair handle showing the manner of mounting one of the supporting rods for the attachment, H I c Figure 5 is a sectional view taken on' line 55 of Figure 3.,

Figure 6 is a sectional detail view showing the attachment stored in its supporting bracket.v

Figure 7 is a 'sectionalqview taken on line 7'-7 ofFigurel.

Referring to the drawings in greater detail the numeral, 1 indicates an invalid chair of any conventional construction and provided with arms2 on; which the novel attachment is mounted; It is to be understood, however,

that thepresent constructionis also'adapted for use on anyothertype of-furniture which,

may-be. provided with the equivalent of the arms 2, so as to attachment. a i c. v,

In the present embodiment of the invention one ofv the arms 2isprovided with a pair of brackets or bearings 8 on its -undersideiin which-is slidably m'ounteda rode; To the g outer endof the rod 4 a block 51s pivoted and to whicha bar 6 is fixedly securedmOnithis bar 6 a bracket or plate 7 is rotatably mount ed and-is preferably spaced intermediate the ends thereof-by meansof'sleeves 8 and; 9. I On the end'ofthe bar 6 remotefromthe block 5a clip 10 is provided which is adapted provide a support" for: the

to engage over the outerend of arod- 1'1.

This rod 'llis slidably mounted on theother arm 2 of the chair by means-of bearings12, and may be slid backwardly into concealed position or extended outwardly inthe same I manner as the rod 4. I i The restfor the support of a lunch tray,

book, newspaper, orthe like, is generally in- '75 plurality of 1 metal strips 14 preferably of dicated 'by-the numeral l3,-and comprises'a angular cross section and supported in paral lel relationship by aseries of lazy-tongs 15 Three of these metal strips are providedand the inner one thereof'is adapted in certain positionsof the rest to bear upon the arms 2.

For this purposegpartsof the ends thereof are bent downwardly as indicated numeral 16 so that two'fingers are provided'on each end .of this {particular strip. These fingers are preferably'covered by sheet rubber or the. like .17 so as to prevent damage to the finish of the chair, and as v-willgappearfrom an inspection of Figure 1, the downturned v fingers 16 engage against? the inner sides of the arms'and thus prevent any lateral movement of therest when in the particular positionshown in Figure l -with its lower edge supported directly on the chai'r'; r p The bookrest or the like as just described,

is connected to the plateor bracket 7 by means ofa pair of. lazy tongs 1 8; whichhave their upper ends connected to themiddle bar 14 of V the rest and their lower ends secured to the plate 7; The manner of securing the lazy tongs .18 to the plate 7 is indicated more Between the; plate 7 and" the head of the eye bolts 19 c1i'ps'21 are inserted and are provided with inturned ends 22 which are adapted to frictionallyengage the bar 6 when the nuts are screwed up-into po'sitionl 'By this" means it will'be apparent that the bolts 19 ,7 and their nuts 20 serve not only to connect the lazy tongs to the plate 7, butalso to lock'the plate 7 with respect: to its bar 6, thereby permittingthe adjustinguoftherest or book sup port in any preferred angular position. As anadditiona l'means of 'lockingthe plate 7 against relativemovementwithrespect to the barv 6, another eye bolt 23 and .nut2 are .7

provided.,; 1' V a Y L; From the construction thus vfar described, it' will be apparentthat the present attach m'ent may be-swung intoposition'shown 1n orby. means of the; lazy tongs18 it a any; angular-position by setting upon the nuts 120 and 24. When the attachment is not desir,ed;for:use, the rest may be collapsed by pressing together. thelthree 1 strips 14: .of angle iron'as indicated indotted lines in Figure 3,

and may of course, by means of lazy tongs 18 be depressed into engagement with the plate 7., By detaching the friction clip 10, the entire-apparatus may then be.swung about the outer end of rodt and brought into substantially parallel position relative thereto; In ,order to store the attachment in an accessible position for-further use a spring clip 25 is secured to the underside of the'arm 2 on whiohtherod lis mounted; It will be apparent that whenthe collapsed apparatus is swung below. thearm 2 as indicated in Fig ure 3-itis free and'may be readily pressed intothe c1ip25, andin 0rder to preventits accidental displacementtherefrom, the end of vthe-plate 7 whichis adjacent the clip 10 is provided with a tongue 26 which is adapted to engagej.-behind"-the vertical'portion oflthe clip 25 ljby a forward movement of the apparatusafteritiis placed inthe clip 2 5.1'This sliding movement of the. apparatus is, f

- course, permitted by the'slid'able mounting of the-rod 4 to which'the apparatusis connected.

lathe operation:ofthe devicea slight rear- .ward movement ofthe collapsed support will release, the tongue 26 from the clip 25 and thus permit thesame to be withdrawn from V the clip-and swung outwardly across the 'frontof the chair 'asindicated in dotted lines 'in Figure;3.- The rod ll is thendrawn outwardly as indicated in F igure3'so asito receivetheclip'lflongtheend of the bar 6330 asto support the device in athori zontal ,posijreadily-swung intoposition for supporting a included within course, permit any 'desired'horizontal ad justment of the attachment; Furthermore, by reason of the lazytong connections bee -tweenthe restand plate7 and the locking nuts 20 and 24, the rest may be arrangedin any desired "angular position for supporting anewspaper, book, or the like.

v From the foregoing description, taken in connect-ionwith theaccompanying drawlngs,

it willbe apparent that I have provided a comparatively simple and inexpensive construction of chair attachment whichimay be lunch .tray, book, orfother :article in; a position best suited to the occupant of the chair, and-that when use .iof thede'vice-is discontinned it maybe readily. collapsed into a compact bundle... or package and-Jswunginto a storage position beneath anarmof theichair and practically concealed from view, The
