Figure 3 is a perspective view fromathe same aspects as Figures 1' and 2, showing ;the:article of furniture made up as a bed. a 11- Figure 4 is a vertical sectional.view-;on-an:en.- larged scale, taken on they line '4-14"of.rFigure;1i", with the direction of view. as indicatedshowing the'upholstery cushion of the davenport back in conventional position, and, in broken line, moved to a position permitting thedavenport to be con verted to a bed. i 1' Figure 5 is. a fragmentary'detail from: Figure '4, on a further enlarged scale, showing the method of attaching the back upholstery of the v davenport to the back support.
Figure 6 is another fragmentary sedtionalqdetail onlapproximately the scale of Figure15, and taken on the line 6-6 of Figure 4, with the direc tion of 'view as indicated, showing the means used to mount the back support of the davenport pivotally upon the arm-rests. 1 I v Figure '7 is a horizontal sectional view on the plane of section indicated by the line 1-4 of Figure 6, showing means for controlling the pivotal movement of the -davenport back support. Figure 8 is a vertical fragmentary: sectional detail on a further enlarged scale, taken onthe plane of section indicated by the line'8'-" -8lof Fig-" Having reference now to the details of-the drawings, #my improved convertible bed and davenport may comprise a main frame Ii supporting a seat mattres's' 'll and havingarm-restsi l3 at each end secured to the frame and forming" part thereof. -One or more of the arm-re'sts is may contatin a compartment i4, closable by 'a 'Ihe'frame H and the seat mattress l2 may have thew'idth of a standard single bed;
door I 5 and of coursethe length of theiseat 'mattress l-23 betweenth'e arm-rests I3 is ofsuitable' lengthf" for a bed.
Each of the arm-rests l3 haspivotally mountedthereon, as shown in detail in Figures 4.:to B,
a back support 11. The two back supportsii'l; are each substantially half the length-:of, the: seat mattress [2 so as to be adapted to be swun to each of the back supports I1, extending nori mally downwardly over the frontal face lfliof' the back support to substantial contiguity with the seat mattress l2 and forming a closure for the cabinet 28. The cushions 22 may besecured' to the back supports I! in any suitable manner permitting them to be swung upwardly, as shown in broken line in Figure 4, but preferably I employ a hinge connection, asshown in Figure 5,
which' permits the cushions 22 to be easily disengaged and removed from the back supports. Plates 23 are inserted in the upper panelling 25 of the back supports H; and haveslots"25 for receiving hooks lfisec'ured: to the rearward sides of the cushions 7,2. F The forward-imargins'21 0f the plates 23, definin'gthe'sl'ots 25 form adequate hinge bars'f'ror'n which the hooks. 26 may be easily disconnected V Y, Each of the back-supports -11 is pivotallybecured by a' 'bearingbracket. 25.! to a pivot post $0,:as:sliown-f in-"Figure 6, the post 39 extending downwardly into the arm-rest |3.:andi there being mounted in a bearing bracket 31'. 'AJcoHar-BZ on the post 3i!v provides; a suppcrtinglibearing for theback support ll, separatingthe lowersurface of the back support and theupper surface of arm-rest l3 sufficiently to permit swinging' 'the biackxsupport without friction on the arm-rest. rr' To limit the pivotarmovenrent cf'the back supportsfllfl to movement between the aligned positions above described invrhich' they form a sofazback, and positions in upward extension of the arm.-- .:ests I3, in which they form head and foot members for a bed, a plate 34 is secured to the lower surface of each back support and has an arcuater'slot 35 describing an'arcof substantially ninety degrees. A plate'tt secured to'theupper surface of thearm-rest 13 serves to locate apost 31, the upper'end of which is adaptedetor travel in thecslot 35. The post 31, accordingly, stops further pivotal; movement of: tlreback support-l 1: whenever either: end of the slot -35 comes into contact with-it. *W-henmy convertible v bed-and davenportis to; be used as a davenport, the back supports?" are; swung into alignment'abovethe rearward margin of the frame H and seat mattress l2, and ,the upholstery cushions 22 are allowed tohang naturally fromthe hinge bars 27,. as shown iii-Figural. The cushions 22'then cover the cabinets 20 and extend downwardly tothe seatmattress l2, and are projected forwardlywby the inclinedv faces I8 of the back supports ll, so as' to' reduce. the effective width of the seatmattress" l=2i-to a width appropriate for a davenport'seat; To convertthearticle of furniture toa bed, it is merely necessary to raise the cushions 22, as shown in Figure 2, so as to clear the arm-rests l3), and to swing the back supports IT to the positions shown in Figures, in upward extension of the arm rests. The cushions 22 are-then allowed to drop as closures to the cabinets 20.
4 In this position, the back supports I! form adequate head and foot members for a bed, permitting pillows tobe banked against either support in a manner comfortable to a person sitting up in bed. Blankets and sheets may be tucked between the seat mattress l3 and the frame H, as with an ordinary bed, as the seat mattress does not overhang the frame. The cabinets 20 are asreadily accessible as thecabinet [4, providing space for storing personal articles:
