CONVERTIBLE'DAVENPORT AND ab 7 Thomas F. Coney, l\l'ew Haven, Conn. Application January 21, 1946, Serial No. 642,524

-'-This invention relates to an article of furniture which may be employed as a combined davenport and bed in that it may be used as a davenport when in folded position, may be unfolded to be used as a half-size bed, and may thereafter be extended to be used as a full-size bed.

In certain of its aspects the present invention relates to improvements in the operating unit for acombined davenport and bed shown in my prior Patent No. 2,328,260, granted: August 31, 1943." In the device shown in this patent, and also in the present device, there is provided a main frame similar to that of the ordinary davenport in that there are provided a pair of end walls secured together adjacent the' rear edges thereof so as to make a frame like that of the usual davenport. Between these end walls is mounted an auxiliary frame which may be moved forward- 1y to a position extended from the mainframe, which frame carries a pair of superposed cushions 'or mattresses, one of which is pivoted to swing'upwardly and outwardly to an extended position, and the other of whichis mounted to be moved vertically while maintained in substantially parallel horizontal position,

The present invention is particularly concerned with the mechanism for holding the slidable frame in any position to which it may be ex: tended and also concerns the provision of auto matically extensible folding legs upon the swinging. mattress or cushion, so that when the'latter' is swung outwardly to extended position the legs will automatically be extended to engage the floor, and when the cushion is swung in a reverse direction to folded position the legs will likewise be moved in a reverse direction and be folded against the side of the mattress in a concealed position.

., One object of the invention is to provide a combined davenport and bed having an extenf sible auxiliary frame which may be slidably ad.- justed with respect to the main frame, and improved means for holding this unit in any ad-.

cushion is swung outwardly and restoring thesupporting legs to their folded position whenthe;

cushion is swung inwardly.

2 Claims. (Cl. 5'-18)" A still further object of the invention is to provide a combined davenport and bed having an auxiliary frame slidably engaged with the main frame for extension therefrom, a cushion pivotally mounted in the unit, and resilient means for supporting the pivotal mounting of the cushion whereby thep-ivotal axis of the latter may yield verticallylwhen subjected to weight. I

To these and other ends the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

- In the accompanying drawings:

To illustrate a preferred embodiment of my in-' vention, I have shown in Fig. 1 of the drawings. a davenport having side frames l0 and I l which side frames are connected by rods I3 and I4 and by the back frame l5. At their inner sides, the side frames l0. and II are recessed or cut away tion and are hollow and contain certain operating I mechanism which will be hereinafter described.

The inner sides of the sectionsv have secured thereto a plate 23 to cover the hollow. portion or chamber which contains the operating mechamsm.

Each of the end sections is provided with, a roller 24 by which it is supported from the floor and which rollersenable it to move outwardly with the rollers in contact with the floor when moved, for example, from the full-line to the dotted-line position'shown in Fig. 4. Also, the end sections may be provided with rollers 25 at the rear edges thereof, which rollers operate in slots 26 in the side frames I and H of the main frame, so that the sliding or extensible unit will be properly supported at its rear end by the main frame in any position of adjustment.

Within each of the end frames 22 of the sliding unit is the operating mechanism for the lower of the two superposed cushions 21 and 28. This operating mechanism consists of a member 29 to the ends of which are pivoted links 136, the links being pivoted at 39a to the frames 22. Also pivoted to the ends of the member 29 are links 3| carrying upon their free ends pins 32 ex tending through arcuate slots 3'31'111 the z-plate fi, which pins 32 carry the lower cushion 21 so that, when the links 30 and 3| at one -end'of the member 29 tend to straightenou-t,the-cushion 21 will be raised from the position shownin'Fig. 2 to that shown in Fig. 3. It will be noted th'at due to the arcuate shapeof the slots 33 the cushion 2 lis movedrear wardly duringathe beginning of. its :upward or raising .movement' andthen again moved :forwardl-y to .'lie in close juxtaposition to the cushion or mattress .28 when the parts, are in. thepositi'on. shown in Fig. 4.

.The.-mattress -28is hinged or. piVOtBd' tO'thB forward portion of-eachof the members '22-.as shown in Figs. 2,4 and .6. .For this purpose a rod- 35 extends :through themattress and projects from-both ends-thereof, this rod being rotatably mounted 52$ its ends in blocks 35-1supportedin casings 3'! in the-.end-frames 22 uponcompression springs #38. It will bernoted that with this construction the mattress 28 may be swung through the "dotted-line position shown :in this figure .to the .full-line position shown finFig. 4'. In the latter position the parts are=adapted to be employed as a=half-size bed. Itwil-lbealso'understood that, as indicated in-dotted linesfin Fig. 4, theentire unit consisting of theframes 22 and bothpf the mattresses .2! and 2.8 maybe slidably moved .outwardly :from the main frame of the davenport tdmakea full-size bed, asvind'rcated in dotted lines in Fig. 4.

.ltwillbe noted -that zthe pivotrod 35- mounted half-waybetween .the upper and lower surfaces of themattress2 8 :so that when this mattresstis swung outwardly to its extended position 'the reverse side thereof will be uppermost, but this uppermostside will be in thesameplane as that occupied by the :uppermost side of .the mattress whenit. was in its folded position'superposed upon themattressfl. .In ordenhowever, for-the-upper surface of .the mattress .21 and 28 to .be at the same level in .the .extended position shown'in Fig. .4 it is necessary to raise themattressfl when the mattress 28 is .swung outwardly.

In order that thismay be effected, a link-40 is ,pivoted at 4 l .to .themattress28, .this linkJeeing provided witha slot '42 to .receivea pin 43. upon the upper end ofalever 4.4..pivotedat 45in one of the end units 22, the lower endiof .this lever being pivotally connected to oneend .of-..a.link 4a, the other end of which-.ispivo-tedlat 41 to the member 29. With this construction, it will be apparent that when themattress 28 is moved from its folded position .to .the .dottedeline position shown in Fig. 2, the link 40 will be moved forwardly so that about .the time the .mattress reaches the verticalposition-shown in dotted lines infFig. '2, the rear end ofithe slot. 42 will .have engaged the pin .43. .This lost motion connection, permitting considerable .movement of the mattressizs'before the lever 44 is.moved, permits the'mattress 28*to :move 'out of "thewayzof the 4 mattress 21 before the raising movement of the latter is begun. When the mattress 28 is moved from the dotted-line position in Fig. 2 to the position in Fig. 4, the lever 44 will also be moved about its pivot to move the member 29 to the left as shown in these figures and thereby raise the mattress Zlto the position shown in Fig. 4. The initial rearward movement of this lower mattress prevents it from striking against the mattress 23 until the latt'erhas been. moved outwardly to a sufficient extent to permit the forward movement of the mattress 2'! as is effected by the upper ends of the slots 33. It will, there- \tore,.- be seenwthat tomove the parts from the folded position shown in Fig. 2 to the position 'show-n Fig. 4' it is only necessary to swing the .cushionml outwardly, and. the cushion 21 will automaticallybe moved upwardly.

Tham'attress 28 is provided at each of its front corners with legs 49 pivoted to the mattress frame: 2.13.59. Theselegs occupy a foldedposition beside the mattress when :the latter is infolded position.. and being extended when the: mattress. is-s'wungwto theposition-shown-in Fig. 4. .Forathis purposeea link 5l=is pivotedat52 to the leg :49, theother end of the link being-curved. downwardly and pivoted at 53 to the link 40 just rearwardlyof thejpivo-t 4. With this construction .it .will

be .seenthatas .the mattress-member 28 moves fromsthe position shown in .Fig. :4 to the position. shown in Fign Z, the link '51 will-be moved for-- wardly-relatively tothe pivot 50.so that the legs 49 will-be moved .inza counterclockwisedirection.

Adjacent the outer ends of the lever are provided pins 66 and 61 projecting through slots 68 and 69 in one face of the unit 22, so that these pins may be engaged by the link 40 when the latter is in horizontal position as it is when the mattress frame 28 is in its folded position or in the extended position shown in Fig. 4. As illustrated in the latter figure, the lower surface of the link 40 will strike the pin 61 and depress the outer end of the lever 6|], thus raising the plunger head 56 into engagement with the main frame of the structure and frictionally locking the auxiliary or sliding frame against movement. When the mattress frame 28 is in its folded position the lever 40 will engage the rear pin 66 and likewise lock the parts against movement.

The action of the Spring 62 tends to keep the pins 66 and 61 at the upper ends of the slots in which they ride and also tends to maintain the plunger head 56 out of contact with the main davenport frame when there is no pressure upon the lever 60. Pressure upon the ends of this lever tends to compress the heavier spring 59 and acts to force the plunger head 56 upwardly. It does, however, permit movement of the inner end of the lever 60 relatively to the plunger after the plunger head strikes the main frame so as to provide for additional movement of the lever if necessary without further movement of the plunger. This lost motion connection between the parts allows for any inaccuracy that may exist in the manufacture or installation of the mechanism.

Springs 10 secured to the frame of one of the units 22 at their upper ends and at their lower ends to the member 29 assist in the movement of the member 29 in a direction to raise the cushion or mattress 21 and thus lessen the effort required to simultaneously swing the mattress 28 about its pivot and raise the mattress 21. It will also be understood that raising the mattress 28 about its pivot 35 whether from the position shown in Fig. 2 or from the position shown in Fig. 4 immediately disengages the member 40 from the pins 66 or 61, and thus relieves any pressure of the braking member 56 on the main frame so as to permit the auxiliary frame to be moved to extended position. In other words, if it is desired to extend the auxiliary frame from the position shown in full lines in Fig. 4, it is only necessary to slightly raise the mattress 28, thus relieving pressure of the member 40 on the pin 61 which will immediately free the brake and thus permit extension of the auxiliary frame.

While I have shown and described a preferred embodiment of my invention, it will be understood that it is not to be limited to all of the details shown, but is capable of modification and variation within the spirit of the invention and within the scope of the claims.

What I claim is:

1. A davenport bed construction comprising a main frame having rigidly connected end sections, an auxiliary frame slidably connected to the main frame for retraction between said end sections and extension therefrom, a cushion member pivotally connected to said auxiliary frame to swing upwardly and outwardly therefrom, a braking member on said auxiliary frame adapted to frictionally engage one of said end sections, said member comprising a plunger movably mounted in the auxiliary frame, spring means urging said plunger out of engagement with said main frame, a lever pivoted on the auxiliary frame and having one end engaged with said plunger, a compression spring disposed between said end of the lever and a part of the plunger, and means engaging the lever on the side of the pivot opposite said end to compress said last-named spring and cause the braking member to engage the end section.
