' My '.invention relates to' a bed-daven'port and particularlyto a convertible device of this character in which provisions are made for utilizing a-full-width; full-thickness innerspring mattress,

suchas' commonly-used on "standard stationary 10 315;. V "I is".

The principal'obj ect of my invention is to providea convertible bed-davenport of this type and 'u'sing' suchafull-sized mattress without "increasingtheseat and back dimensions of the dawnport beyond comfortable limits and pleasing appearance;

' Another "object is to provide a davenport of this type which includes a bed member having suitable frame andspring means separate from the seating members (wliich require a different type of springs *for comfort) and whereby the bed is nct'used-as a seat nor the seatused as'a bed,

1 A'nothe'r object is to provide a davenport of this typevvhich facilitates the convenient-placing of bedding materiallsuch as quiltablankets, pillows,

etc on the front of the mattress prior tcclosing tlie'device into a davenport and whereby such beddingmaterial is carried by the: mattress to a position under theseat, thus eliminating any awkward stuffingor cramming of such materials into inconvenient compartments.-

- A further object of the invention is to pro v'idea inode f foperationin which conversion from a davenport toe-bed orvlcversais accomplished in more'than a single operation in order to divide the'wor'k into easy stages and eliminate excessively difficult, "operation." Another object" is to provide a bed davenport which may remain disposed against a wall ofa roomwhen converted intoa bed, and whichwhe'n opened into a beddoes not leave'the rear edgeof the bed portionjdisposerlagainst such wall nor ih "close juxtaposition to aback rest or other obstruction such provision facilitating the draping of bed covers overthe edgeof the bed.

Another object is to provide a bed or sleeping portion at a higher level than the seati of the closed daifenport- A further object is to provide a bed daveriport in which the moving parts are counterbalanced throughout 'their'imovement' and in which a minimum'amount of springs, levers, links,'etc., are employed. l 1 Another object is to provide a bed-davenport in. which the bed sections are carried-principally by rollers operating upon tracks and which cooperate to convey the sections fro'ma stored po sitionu-w'ithin the closed davenportt'o a bed =pos'i Other objects are toproyide means forputilizing a reversible mattress without seams, joints, ridges or depressions and which is uniformly sprung throughout, such means being capable of handling amattress of this type without ex-.

cessively acute bending of the mattress andwhich in folding is raised simultaneously at'the front and backyedges during the; initial operation whereby themattress will be flexed prior to being shiftedinto its final position thereby preventing any inclination of the mattress to slip or?v become dislocated on the frame ofthe bed and eliminating thenecessity of fastening the mattress to the bed-frame. i a

f In the accomplishment! of -these;objects I have provided a stationary main frame for housing, a

seat member adapted-to be turned over forwardly into an inverted position in front'of the'main housing, a mattress or bed frame comprising articulated sections; the rear section of which carries at each end a-pairof spaced rollers adapt ed to engage trackscarried by the end members of thehousing, the tracks being so shaped and disposed that when the rollers traverse the tracks the bed sectionwill be carried from a vertical position at the rear ofthehousingto a horizontal position at bed height a back rest hinged at its'top .to the' rear bed section and held in an uprigh'tback-rest position when the bed section isjvertically disposed andwhich is adapted'to be carried by the bed section'to a horizontal 'posi-p tionwhen the latter is so disposed, after which it may be swung'balckw'ardly out-of the' way; a centrall bed section articulated with the rear section and having centrally of each end rollers which'engage tracks carried by the housing endmembers and adapted to carry this section from an inclined position at the rear and bottom of the housing to a horizontal position: forwardly of the rear section'and on a level therewith; a

front bed-section articulated-with thei'central section and adapted to be raised at the front from a position at the bottom of the housing and to be pulled forward together with the other sections into a co-planarhorizontalposition with the front sectionresting upon supports carried bythe invertedseat member; links interconnecting the front bed section withthe seat member at'each end andadapted to raise the front edge of the front bed-section'to approximately bedhei'ght when the seat isinverte'd after which the links act-as guides forthe front sectionas it is swung forwardly on thelinks toits=final forward position, bringing the' entire bed frame into horizontal position; and 'a'spring means for aiding in also aiding in balancing the parts during other operations.

In the drawings, Fig. 1 is a fragmentary perspective view of my device; Fig. 2 is a vertical section taken on 2-4, Fig. 1, showing the device as a seat; Fig. 3 is a vertical section corresponding with Fig. 2, and showing the device opened as a bed; Fig. 4 is a fragmentary horizontal section taken on 4--4,"Fig.. 3; Fig. 5 is'a' fragmentary front view showing the device opened; Fig. 6 is a vertical section showing hinge for back rest memher; Fig. 7 is a longitudinal section taken on:

'I-I, Fig. 6 showing hinge and roller supporting means; Fig. 8 is a vertical section taken on 8--8, Fig. 3, showing roller supporting means; Figures" lifting the seat member from a seat position and "ance for the weight of the seat and facilitating V lifting it from the seating position.

9, 10, Hand 12 are diagrammatical views show- I ing theaction .of the device and representing operative positions intermediate the closed posi-" tion of Fig. 2 and the open position of Fig. 3.

Throughout the various views the same numerals represent similar'parts.

In more detail and with reference'to the drawings a frame, or housing is provided'including end walls I, a back panel-board 2,- a front panelboard 3, a floor 4'and a horizontal brace 5. The end Walls and front panel board are upbolstered with suitable material 6 and I respectively. A cloth -back 8, serves to. complete the housing into a dust-proof compartment when the device is closed.

The walls I at each end of-the" davenport support tracks 9, I0 and II for carrying the hinged bed frame which is provided 'with rollers I2,. I3 and I4 at each end for engaging: the tracks. The bed frame comprisesthree sections, hinged through the end members H.415 and; I! for articulation and forming rear, middle and front sections respectively. Members H5. at either end of the bed are joined longitudinally by the rear rail. I8, whilethe members HJare interconnected by a front rail I9. End members I6 are joined by a brace which maintains parallelism between the members I1 and is underslung to provide room for depression of the spring fabric 2| carried by the bed frame. The spring fabric 2| may be of any conventional type'and is designed to support a standardinnerspring mattress indicated by the dotted lines 2 IA, rcpresenting the mattress in' phantom; 22 is an upholstered'lback rest which has endmembers 23-attached to brackets-24 pivoted on the roller supporting studs 25,: (Figs. 6 and '7 show this feature in detail). Longitudinab members 26 and 21 attached at each endto'the brackets 24 form atop member for the back rest while a longitudinal member 28 forms a bottom member for the back rest. Springs 29 of the well'known' No-Sag type (disclosedin Patent No. 2,002,399 issued by the U. S. Patent Oflice) span the space from the top to the bottom members of theback rest to form a spring base for the padding assembly 30. 1

3| is an upholstered seat which has endmembers 32, a frontrail33 attached to the-angle bar 34-and-a rear rail 35 attached to the angle bar 36. The angle bars are secured to the end membersi32-toform a seat frame and springs 31 having hooked ends which engage openings in the 'angle'bar 36 are secured at the front to the rail 33 and form a basefor the coil springs 38;.Which support the padding-assembly 39;

Hinges 40 interconnectthefront panel board 3 and the front angle bar 34 whereby the seat is articulated with the housing of the device so it Links 41 pivoted at one end to the seat and members 32 at 48 and to the front ends of the front bed sections I1 at 49 provide supporting means for the front bed section.

50 is a hand strap by which the seat may be operated.

It will be notedit-hat the back rest is supported entirely by. the :bed framethrough-t-h'e studs '25 which carry the .rollers:-I-2and that'the back rest .isqpivotedronr these studs so that its end members 23 may rest against the bed frame member I5, thus. the back rest moves with-the bed frame when the latter i's'transferred from a vertical-to a horizontal position and vice versa. It is also noted that the bed frame :issupported entirely-by the rollers-I 2, -I3;an'd. I i-(preferably of theball bearing wtype) and-bythe links" while being moved from one position to another. The rollers I2 andl3 carried by members I5 andbeing guided and supported by the tracks 9 and Hi respeetivelymaintain a positively controlled relation between" the members I5 and the housing-of the device'throughout its movement from -;a= vertical position to a.- horizontal position. I The intermediate frame. members I 5 being articulated, at their rear ends-with. the frame members I5f-and being-supportedcem trall-y through the-rollers by the tracks II also maintain a positive relation with the rear section-members and withthe housing of the device throughout the movement from a seat positi-on' toabed position. The front section members Il' being articulatedwiththecentral sections .i6 and having theirfront-ends carried by the links4'l also maintain-apositive corelation with the other. parts throughout their travel.

The end members 32- of the seatcarry legs 5| adapted to slide within the supports 52 and 53,

the legs being retained bythe foot portion 54 and the flange 55 carried by the leg. A weighted catch- 56 is loosely pivoted on the pin-51 and moves freely within aslot formed in the seat end member 32 (shown in section in Fig. 3). Whentheseat is turned forward the legs 5| slide downward to extendthe footed end to form a support for the seat-unit-while the catch 56 by its own weight assumes a position to engage the flange 55 of the leg, locking the latter in position; When the seat unit is turned backward the catch 56 disengages the-flange 55 and the leg slides downward, the footed end-receding below'the level of :the seatsurface.

Studs fad-projecting outwardly of the seat ends 32 are adapted to be engagedby thelinks 41 to limit the movement of the latter.

Rollers I3 and I4 are carried by supports 53 and respectively (shown indetail in Fig. 8) .-In operation 3 from aseat'or closed position as Fig.2 the seat israised :(aided by the springs 46) as in Fig. Q'Whereby; through thezlinksfl the front e of the front bed-.sectionis lifted to a point in line with the hinges) whereupon the links engage the studs 58; Further move ment 'ofthe seat unit forwardly and downwardly as in Fig. 10 causes the links to pull the front bed section forwardly slightly whichsimultan'e ously brings the other bed sections into new positions. The frontportion of the middle section in moving forward is caused to rotate somewhat on the axis ofthe rollers (the ro ler m -f in from the inclined rear pOIti0nof the track.

" Themattress (shown in phantom in the various viewsfby dottedlines 2IA) .is not at any time subjected to excessive-bending. :Sincethe bed section-is articulated at two places and the mattress is required to assume only about a right angle at the extreme ends the divided angle is only about 45 degrees. This permits the use of a standard i'nners'pring mattress of: the usual deep construction ordinarily used on stationary "Due-to thearrangemen'tcf the-"deviceland the vice is in: closed positionsuflicient room is providedlfor a mattress of full thickness'without ward andupwardon the front rail IQ of the bed frame whereby (see Fig. 11) the middle bed section, carried by rollers [4 operating upon the horizontal portion of tracks ll is rotated in its forward movement to a horizontal position and the rear section is carried downward andits low er portion moved considerably forward on the inclined portion of tracks ID (the upper-portion o'fthe rea'r section being guided by the Vertical section isflowered to nearly a horizontal posi-] tion carrying the back restjwith it. It will-be notedthat at thispoint-the lever 431s engaged by "the front rollerishaft 60 whereby further for'- Ward movement is impeded" by thejsprings 4t,

,thus' compensating the otherwise unbalanced weight of the front bed section. I I -A'further movement downward on the'frontrail crowding and additional space isprovided ontop of -the mattress under the seat portion for bed clothes, 'quilts, blankets, pillows, etc., which may be placed 'on the front of the mattress while'the device. is opened as a bediand carried with the mattress"toj the closed p ositi'on, thus eliminating the usual awkward procedure of stuffing the becl ding material into a box under the seat The structure herein provided also permitsuse of a mattress of standard bed width without increasing the-{{depth of theiseatfront-to-back nor. the height of'the backrest. By way of com-I bined widths do not provide a-bedi'of comfortable dimensions, Often in practice manufacturers resortv to unusual front-to-back widths of seat or'a'nexcessivelyhigh back in order to providea wide'rfibed but this only .makesan. uncomfortal9jcompletes the second operation and'brings all the bed sections to a horizontal'co-planar posi tionwiththe front bed section resting upon the.

It will bejnoted that throughout the second operation themoving parts are practicallyfbfalaneed. to provide easy movement. ,Wl1 ile; the front bed section is being raisedth'e rearsection is being lowered (from Fig. 101to Fig. 11) andb the central section'maintains a .uniform level.

While the front section is being lowered the middle section isjbeing raised (from Fig. vl1 .to

- Contrary .to usual' objectives' in mfolding'fbed I I da'venports wherein they are j designed to 'c'omplete "the opening" or closingf operations by a singlet-movement of: some part thereof, and which ,necess'itatesthe' use of considerable force due to the limited movement-involved; the present structureris designed to lessen the labor of open+ ing or closing by dividing the total operationintothree easy stages, heitherbf which require any excessive iexertion to perform. For instance in opening,. the seat is'pulledover as one-opera l tion without" appreciable movement of the-other the springs 46 act to compensatej'the qtherwise unbalanced weight of the-front section,

When the bed sections are in ajhorizontal posi- 1 tion as in', Fig. 3 the rollers l2, l3 and I4 occupy horizontally disposed sections of the tracks whereby weight or pressure on the bed-sections v does not cause movement and it will be noted that the "front bed-section must be raised; bef,o re

'These' easy'operations are-reversed to closethe device-into seating posi It willqbeobserved that in the present structure; without pulling the davenport itself away from :'the Wall, the -rearedge of the mattress is some distancefromthe-back rest -when in' a the' bed-position providing ample, room-for bed cov-' ers to drape overthe edge. This is more desirable than .a structure wherein: the mattress or bed" portion; abuts against the backrest or against a wall when .opened. g jt'Pr'ovision' is made-for a'soec'alled soft front seat portion wherein a deepf-spring action is allowed.
