FOLDING Bnn f Application mea `Au'gust 22, 1928;" serial No. 301,185.

The presentinvention relates to folding couch or day beds of the general type consisting of-a main stationary frame section and a movable or extension bed section and in which the extension bed section is mov'- able either into superposed relation with the stationary section to form a couch or seat or laterally of the stationary section to `form a double bed. Morel particularlymy inven-` tion relates to beds of this type in which the stationary and extension bed sections are each provided with a mattress support ing spring structure having helical springs of a depth normally V'usedin stationary beds of this size and in whichithe spring structure oi' the stationary section is on aninner movable bed section, which is elevated or low` ered Vsimultaneously with the moving of the tions respectively. f Y

The general object of my invention is to provide an improved construction yand jarra-ngement of the various partsof a couch bed of the type described.` A more specific object of my invention is to provide simple and effective means for assisting the user in simultaneously moving the spring structures of the stationary and extension sections to ither the open or closed positions. A iur#- ther object omy invention is the provision` of a storage space for the mattress and bed-y ding between thedeep helical 'spring struc-k tures of the-sections when they sections are in the closed position.

The various features of novelty which characterize my invention arev pointed Outwith particularity in the claims annexed to and 'forming apart of this" specification. For a better understanding of lthe invention, however, and the advantages possessed by it reference should behad tothev accompany' ing drawings and descriptive Vmatter Y in which I have illustrated and described a pre l ferred embodiment of theinvention.v

Each end frame B -is made of an angle bar bent toprovidevertical legs B and B2 and a horizontalzportion B3.. vA horizontal cross bar Btfconnects' the lowerportions of the legs Bf .and B2. Side iioor bars BG extend longitudinally between the frame4 members B. Reinforcing corner pieces B5 connect the horizontal portion Ba to each of the legs. A second:'horizontall cross bar C formed of angle iron `hasfits ends connected to the legs B- andfB'2Sat' points intermediate the bars B3` and'B; AIheganglebar C is arranged with. its'y horizontal leg C extending outwardly between lthe legs B. and B2 and its yvertical-legV C2provided withl a pair of nar* extending slots C3V andy row Vllongit,udinally @horizontally spaced apart.A

The main stationary frame section iszproplan view of the bed in the n,

videdgwith an; inner movable bed section consisting of a Spring structure D having a rect'angular'spring frame D of angle iron, f

aseries of helical lspring coils D2 suitably connected at ytheir, upper and lower ends, anda border rod D3 supported by and connected'ito the' 'marginal spring coils. The lower ends ofthe marginal spring coils are connected 5to. the frame` D.y 1

y. The .extension bed section which is alsovr positioned' between theframe members A" is` also providedlwitlra spring. structure `E similar tothespring structure D of the main section eandcomprising la rectangular frame E', helicalcoils E2 and ,border rod E3; Vertical legs vEare secured to the two outer cornersof the frame Eand' are slightly 19 spring structure-E withv the extension springalone serving as a resilient support for the occupant. The space between the springsv can be utilized as a storage space for the main spring mattress andother bedding.

The spring structures D and E are pivotallyconnected to the end-frames B and to each other in such a manner that when the extension spring .E is moved to the open position, the main spring structure will. be simultaneously elevated-to substantially the same position occupied by the extension,

spring in the closed-position of 'j the bed.

The pivoted connectionsat each end com- A prise a pair of parallel leversy or: links F 25'and Gr,'the upper end of the linkA F being inwardly offset and pivotally connected tothe adjacent end bar. ofthe trame-Efat one end thereof and the upperl end of the link G also being inwardly offset; and pivotally ilconnected tothe end` barV at a pointhorizontally spaced from-'the pivot connection-v of the 1linkv F. The pivoted end of. the link Gis enclosed by the Ul-shaped'bar E5.

The link F is providedwith aprojecting 25 stud F2 at a pointadjacent its lower. endv and positioned inthe slot@3 in the vertical leg of the cross-bar C; :The link GI is similarly provided with a stud G2 positionedin the slot C2. A rigid distance link H- coni 10j nects the studs F2 and Gg'together 0n the' outer side ofthe cross bar4 verticalleg. The links F and G are provided with rigid lateral extensions F3 andG3, respectively, projecting downwardly atan angle from points Jon the links immediately' above the studs F2 and Gr2y respectively. Braces Fv'and G2, respectively, reinforce the connections between'the extensions F2" and Gr3v and their lrespectivelinks.. The lower endsof the eX- 59 tensions are inwardly-.offset and pivotally connected to the adjacent` endlV barzof the spring frame D Aat horizontally spaceda points by pivot pins F5 andG, respectively.

A distance linkFK isfpivotally connectedto:

55 oneend-oly the crossjbar. C adjacent .the leg B andhas itsopposite end pivotally connected lto the eXtensionF3`at a point-r K2'on the extension abovefthe pivotal connection ofthe-extension.with-the frame D. 60,' v

nected to the correspondingnbrace at the opposite end off the bed by-anangle bar M;

.end ofthe slotsC3 andC4.

'lhelbrace Gr4 as shown in Fignl? projects beyond the linkG andi is positively condownwardly beyond the stud F2. A tension spring O is connected between the lower end of the link N and the frame leg B2 at a point immediate below the cross bar C. A second tension spring P is connected between the link F at a ypoint above the stud F2 and the legB2 at a point above the cross bar C. i

The parts have been described particularly-with reference to Figs. l-3 where the bed sect-ions Vare shown inA the closed position. Then it isV desired to move the sections to the open position, the side bar of the eXtenv sion trame-E is grasped by the user and the extension section littedupwardly and outwardly; This movement is initially assisted by the spring P which is in its extended position when the sections are in the closed position. Simultaneous with the movement oiithe extension section the spring structure Dis moved upwardly in a substantially perpendicular distance lin K with the extension F3 of the link F. The pivot points F2 and G2 move slowly to thek right while the link Kis movingfrom the position shown in Fig. 1 to a substantially horizontal position. On a further upward movement. of the links, the pivot` pins move to the left until the extensionsectjion is in the open` position. At that point. the pivot pins are at the extremel left The movement. of the links F and Grv fromV a substantially vertical position to the open position of the sections shown in Fig. t is accompanied by a tensioning of the spring O, which thus prevents a tool rapid downward movement. of the extension section.

The extension sectionis supported in the open position by the legs F1* and by the upperportion of the link Grk contacting with the bent portion of'v the U-shapedv bar` E5. Asshownin Fig. Atthe-springs of both sections are at the same levelwvhen the bed is in the open position andthe adjacent. sides of the springs are Yslightly spaced apart.

There is no tendency for the inner, bed section to drop and the'extension section to risc; due to a heavy load on the spring D as such loads are transmitted ldownwardly to the supporting links at points on the side of the link pivots tending to hold the sections in the open position. XVhile it is preferable that the user grasp the middle portion of the frame side when j operating they bed, the movements can be effected at any point along the frameA side. The bar- M effects a positive connection ybetween the operating4 mechanism at each end of the bed.

Vhen it is desiredto restore' the bed to' the closed position, the extension section is lifted and moved inwardly. VThe spring action in this case is the reverse ofthat occurring during-the opening movement and thespring O- first assists in the return movement andthe path dueto the connectionof the spring P later retards the lowering of the extension section into position. The eXten-v sion spring is supported inthe closed position partly by the link G contacting with the other bentportion of the U-shaped bar E5, partly by the legs E4 and partlyby the bar M which contacts with the lower side of the frame E.

My invention is characterized bythe sim-` plicity, strength and ease of manipulation of the construction, by the facilities for storing the bedding with spring structures of this type, by the small amount of floor space required in both the open and closed positions of the bed, and the maintenance of the supporting spring structure at the same high level in both the open and closed positions.

While in accordance with the provisions of the statutes, I have illustrated and described the best form of embodiment of my invention now known to me, it will be apparent to those skilled in the art that changes may be made in the form of they apparatus disclosed without departing from the spirit of my invention as set forth in the appended claims and that in some cases certain features of my invention may be used to advantage without a corresponding use of other features.
