Y., assignor to United States Cabinet Bed 00., Brooklyn, N. Y., a corporation of New York Application August 2, 1941, Serial No. 405,152 Claims. (01. 5-13) This invention relates to couch beds in general and more especially to couch bed having three bed sections such as disclosed in my copending application for patent, Serial No. 381,265, filed March 1, 1941, which became Patent No. 2,264,090 5 on November 25, 1941.

Among the objects of the present invention, it is aimed to provide an improved three section bed couch requiring a minimum amount of effort to operate, which may be operated from couch formation into bed formation and back again while disposed closely adjacent to the wall against which the bed couch may be located in couch formation and the outer section of which may be supported in bed formation not only at its outer free end but also at its inner end where such other bed section is connected to an intermediate bed section.

It is also an object of the present invention to provide an improved three section bed couch having an interchangeable back and bed section which when moving from back formation into bed formation will have its rear lower edge descend without at any time projecting rearwardly of the vertical plane passing through the rearmost edge of the back section in erect position, and which, in turn, when moving from bed formation into back formation will again not pro-e trude beyond a point lying in such vertical plane whereby the main section of a couch bed made according to the present invention may remain stationary against a wall both in couch formation as well a in bed formation and while moving the back member into and out of bed formation.

It is still another object ofthe present invention to provide an improved linkage for the leg members of the third or outer bed section whereby the outer end of the intermediate bed section as well as the third and outer bed section will be effectively supported in bed formation.v

These and other features, capabilities and .advantages of the present invention will appear from the subjoined detailed description of one '45 specific embodiment thereof illustrated in the accompanying drawings in which Fig. 1 is a side elevation partly in section of the couch bed in bed formation;

Fig. 2 is an enlarged fragmental detail;

Fig. 3 is a fragmental plan of the couch bed in bed formation;

Fig. 4 is a side elevation partly in section illustrating an intermediate position when moving from'bed formation to couch formation;

Fig. 5 is a side elevation partly in section illustrating the couch bed in couch formation.

Fig. 6 is a fragmental detail of one of the side bars.

In the embodiment illustrated there are provided two side frames I and 2 to which there is secured the frame member 3 consisting essentially of a rectangular angle iron portion having two end bars 4 with the vertically extend- 0 ing webs extending upwardly from the outer sides ends of the uprights 8 and connecting the two there is provided the angle iron bar l0 having one of its webs extending rearwardly at the upper end of said bar l0. At the front corners of the frame member 3, that is, at the ends of the side bar I, there extend the upright angle iron bars ll each having one of its webs extending rearwardly along the sides of the end bars 4. To the inner faces of the upper ends of the front webs of the uprights I] there is secured the cross bar I! which is deflected inwardly'at its intermediate portion and has secured to the outer face thereof the flat bar I3 extending down to and secured to the inner face of the upwardly extending web of the front side bar I. The frames l and 2 are secured to the frame member 3 by bolts l4 extending through the uprights 8 and by the bolts I5 extending through uprights ll. To the front face of the upwardly extending web of the side bar I there are secured the hinge plates l6 connected tothe hinge plates I! by the pins 18 which hinge plates [1 are secured to the front footboard l9 in erect position'having an upholstered outer portion 10 to serve as an outer'finish for the front footboard of the couch bed in couch formation. In bed formation the footboard I9 is swung downwardly to clear the spring mattress of the intermediate or first bed section 20.

To the rear of the intermediate bed section 20 in bed formation there is provided the bed section 21 which also constitutes a back member in couch formation,serving at one time as a bed section in bed formation, shown in Fig. 1, and at another time as a back member in couch formatiom the position shown in Fig. 5. To the front side of the intermediate bed section there 26 of the bed section 2| and at its front ends there are pivotally connected the fiat links 21.

The lower ends of the flat links 21 are provided 1,

with pins 28 slidably mounted in the slots 29 of the upwardly extending webs of the end bars 4. In the present instance the lower ends of the flat bars 21 extend along the inner faces of the end bars 4. I

The intermediate bed section includes a 7 metal frame portion 3!] and an upholstered or mattress portion 3| secured to said metal frame portion 30,, The metal frame portion 30 in the present instance is provided with two end angle bars 32 connected to one another by two down:- wardly extending transversely extending bars 33 and 34.

The ends of the two end angle irons 32 are free, that is, are not connected to one another by side bars, so that the mattress portion 31 and its supporting flat spring 36 may freely flex downwardly throu hout the entire width of the intermediate section 29.

On each side of the intermediate section 20 and pivotally connected to the outer face of one of the side bars 30, there is provided a flat bar 3"! near the rear end of a sidebar 30, which side bar is in turn pivotally connected at its other end to the inner face of the upwardly extending web of a side bar 4. Nearer the forward side of the intermediate bed section 20 and also at each end thereof there is pivotally connected a bent lever 38 to the outer face of a side bar 30, the pivotal connection 39 coinciding in the present instance substantially with the elbow in the bent lever 38. The lower end of such bent lever 38 is pivotally connected to the inner face of the upwardly extending web of a side bar 4 near the forward end of such side bar 4.

So that the intermediate section 20 may operate With and cooperate with the rear bed section 2!, the rearmost link of each set of links 25, 21

has pivotally connected to the inner face thereof,

in the present instance, about one-third up from its lower end one end of the flat link 40 while-the other end of such link is pivotally connected to the outer face of an adjacent link' 3?! also'abput one-third up from the lower end thereof. In addition, to the outer face of each link 31 between the link 49 and the sidebar 4, there is pivotally connected one end .of the link 4! while the other end of such link 4! is connected to the pin 2-8 on the inner face of a link 27. So that the intermediate section 20 may operate with and in turn lower the footboard l9 into the position shown in Fig. l in bed formation and into erect position, that shown in Fig. 5, in couch formation, each lever 38 has pivotally connected intermediate its length to the outer face thereof, one end of a link 42, while the other end of .such'link is pivotally connected to a bearing .43 at oneen of the inner face of the footboard l9. Y

The outer" or third section 22, as shown in Fig. 1, has not connected thereto a mattress member, but, see Fig. 3, has its end ars 4 onnected to. one'another by the flat sprin ifi bll 45. The outer ends of the end bars 44 of the section 22, looking at the same in bed formation, has connected thereto the side bar 45. The end bars 44 preferably as shown consist of angle irons with one of their webs extending upwardly along the outer end thereof.

So that the outer bed section 22 may operate with and cooperate with the intermediate bed section 20, there are provided three pairs of links,

one pair 4! connecting the inner ends of the end bars 44 of the section 22 with the side bars 32 of the intermediate bed section 20, another pair 48 connecting the links 41 with the bent lever 38 and a third pair 49, being bent links in the present'instance, connecting the side bars 44 withthe upper ends of the bent levers 38. More particularly, each link 41, being angle iron, is

bar 44 while the other end of such link 41 is pivotally connected to the inner face fthe 1 1 Wardly extending web of a side bar 32 at apoint removed from the outer end of suchside bar 32 and intermediate such outer end and the pivotal connection of such side bar 32 with a bent lever 38. Each link 48, of flat stock, is pivotally connected at one end, to the inner face of, a link 41 removed from but near to thepivotal connection 50 of such link 41 with a sidebar 44 while the other end of such link 48 is pivotally connected to the inner face of the extension of the bent lever 33 immediately above the pivotal connection 39. The pin 5| constituting the pivotal connection between such link 48 and the extension of the bent lever 38, see Fig, 3, extends across andinto recess'l32 in the upwardly extending pin 5! a predetermined distance toenable the outer bed section 22 and the bed section 20 to aline with one another in bed formation and in addition to cooperate with the links 31, 38, 2'5 and 21 properly'to position the intermediate bed section 20 with respect to the bed section 2|. Each bent link 49-has one of'its ends pivotally connected to the inner face of the upwardly extending web of a side bar 44 removed from but adjacent the pivot pin 50, while the other end of-such link 49 is pivotally connected to the inner face of the upper end of a bent'lever 33. By means of the bent levers 49 and 3 8, the link 4! and th ooper ti n of the levers 49 and .38 with the h rizontal webs of the side ba s 4 and 44, respectively, forming stops in couch formation, that shown in Fig. 5, the portion of the bent levers 38 between the side bars 32 and 4,wil l rest on the horizontal webs of the side bars 4 as a stop, and the portions of the bent levers 49 nearest the side bars 44 will rest against the lower faces of the horizontal webs of the side bars 44, forming stops to maintain the bed sections 30 and 22 in the spaced relation shown in Fig; 5'to form a compartment for the cushions 3| and 6B. The outer bed section 22 is provided with two pairs of leg members 52 and 53 arranged to be folded up in substantial alinement with the end bars 44 of the outer bed section in couch formation, see Fig. 5, and to be extended into supporting position in bed formation, that shown in Fig. 1. So that the leg members 52 and 53 may operate with the bed sections 22, 20 and 2|, when being moved into and out of bed formation, there are provided two pairs of links 54 and I55, in the present instance composed of flat stock. More particularly, each leg member 52 isv suban end bar 44.

stantially straight and has one of its ends pivotally connected to the pivot pin 50 and along the outer face of an upwardly extending web of Each leg 53 has an elongated portion 55 and a short extension 56 slightly bent relative to .the portion 55 and is pivotally connected by a pin positioned'at the elbow of the leg 53 with the leg 53 pivotally mounted along the outer face of the upwardly extending web of the end bar 44. As shown in Fig. 1, the portion 55 of each leg member 53 corresponds in length to a leg member 52.

.The links I55 are provided to connect one leg member 52 of each pair to the short extension 56 of-each leg of the other pair of leg members 53. Each link I55 has 'one of its ends pivotally connected'to the outer face of a leg member 52 about two-thirds up from'the outer free end of a leg member 52, while the other end of such link I55'is pivotally connected to the outer face of the extension 56 of a leg member 53 removed from the pivot pin 51 and adjacent to the free end of the extension 56. The links 54 are provided to connect the bent links 49 with the extensions 56. Each link 54 has one end pivotally connected to the inner face ofa link 49 a short distance removed from the pivotal connection of such link 49 with an end bar 44, while the other end of such link 54 is pivotally connected to the outer face of the free end of an extension 56.

To serve as a brace for the inner ends of the end bars 44 and therefore for the inner end of the outer bed section 22, adownwardly depending cross bar 58 connects the two links 4'! to one another at a position where it will clear the adjacent ends of the bed sections 20' and 22 in bed formation, see Fig. 1. To counteract the weight in the interest of operation when moving from bed formation into couch formation, and in turn to absorb the shock when moving from couch formation into bed, formation, a pair of springs 59 are provided each spring in the present instance, being connected to an upright 8 at one end and to the pivot pin 60 connecting a link 40 to a link 25.

In turn, to counteract the weight in the interest of easy operation on moving from couch formation into bed formation and in turn to serve as a cushion to ease the collapsing blow when moving from bed formation into couch formation, a pair of springs 6| is provided. Each spring is connected at one end to a link. 62 and at its other end to the pivot pin 63 connecting a link 48 to a link 41. Each link 62 in turn is pivotally connected at its other end to the outer face of a bent lever 38 between a pivotpin 5| and a pivot pin 64 connecting a bent lever 38 with a link 49. 1 v

The mattress member 3| of the intermediate bed section 20 is hingedly connected by a fabric hinge 65 to the mattress portion 66. The fabric hinge 65 is disposed at the outer upper side of the mattress member 3|. Extending from the inner upper side of the mattress portion 3| there is provided an extended sheet of fabric 61. In bed formation, see Fig. l, the sheet of fabric 6'! preferably composed of a material such as mattress ticking, is folded over on to the decorative surface of the upholstered inner bed section 2| and the mattress portion 66 is folded over on to the spring fabric 45 and frame of the outer bed section 22. In couch formation, see Figs. 4 and 5, initially the fabric 61 is folded over on to the upper face of the mattress member 3| and then the mattress member'66 folded away from the outer bed section 22 on to the fabric 61. Thereupon, when the transformation has been completed from bed formation into couch formation, the bed section or back member 2| will be substantially erect, the intermediate bed section 20 and its mattress members 3| and 66 nested downso that the end bars 32 are disposed adjacent to the end bars 4 and the end bars 44 are disposed in substantial alinement with the then upper face of'themattress member 66, the seat cushion or cushions 68 are placed upon the spring fabric 36 of the frame 30, as shown in Fig. 5, which seat cushion or cushions 68 will extend from engagement .with the lower end of the back member 2| to the upper edge of the footboard I9, the spring fabric 36 thus forming with the end board 10, a top and front wall respectively, of a compartment for the mattress members 3| and 66.

As will be clearly seen from Figs. 1, 4 and 5, during the transformation from bed formation into couch formation and .in turn from couch formation into bed formation, the bed section or back member 2| will never extend beyond the rear upper extension 69 of the side frames and 2. Consequently, if the couch bed is positioned against a wall with the portions 69 of the side frames and 2 disposed adjacent to or engaging a wall of a room, it will be unnecessary to move this portion of the couch bed when converting the same from couch formation into bed formation and in turn from bed formation into couch formation.

It will also be seen that in couch formation the leg members 52 and 53 are neatly folded away out of view and in turn in bed formation, that shown in Fig. 1, such leg members will effectively cooperate to support not only the outer bed section 22 but also cooperate to support or aid in supporting the outer side of the intermediate bed section 22. Furthermore, the cross bar III will support one end of the inner bed section 2| in bed formation and aid and cooperate with the links 25 and 21 to support such bed section in prone position, shown as slightly inclined to.

simulate a bolster or headrest in bed formation.

In other words, one advantage of the invention results from the combination of a fixed frame 3, a first bed section 30, a second bed section 22, and two pairs of leg members 52 and 53 with a first pair of levers 38 pivotally connecting said first bed section 30 to said fixed frame 3 to control the elevation of said first bed section 3|], a first pair of links 41 pivotally connecting said second bed section 22 to said first bed section 30,

both pairs of said leg members 52 and 53 being pivotally connected to said second bed section 22 with one pair of said leg members .53 having bent extensions 56, a second pair of links 54 pivotally connected to said extensions 56 and also pivotally connected to the other pair of leg members 52, a second pair of levers 49 pivotally connected to said first pair of levers 38 and also pivotally connected to said second bed section 22, a third pair of links 54 pivotally connected to said extensions 56 and also pivotally connected to said second pair of levers 49, and means 31 supplementing said first pair of levers 38 to pivotally connect said fixed frame 3 with said first bed section 30, all contributing to enable said bed sections 30 and 22 at one time to be supported in alinement with one another and with the links 41, with the 'means 31, levers 38, and leg members 52 and 53 in upright position, see Figure 1, and at another time, see Fig. .5, enabling the bed section 3.0 to be .depressed relative to the fixed frame 3, 'with the bed section 22 spaced from the bed section 30 to form a compartment therebetween for the mattress members 2!! and 6.6 with the links 41 now erect and the means 31, portions of the levers 38 and leg members 52 and 53 collapsed.

Another advantage of the invention results from the combination of a fixed frame 3, a first bed section 30 and an interchangeable back and bed section 26 with a pair of levers 38 pivotally connected to said first bed section 30 and to said frame 3 to control the elevation of .said first bed section 30, a first pair of links 31 pivotally connected to said fixed frame '3 and to said first bed section 36, a first set of two pairs of links 35 and 21 pivotally connected to said interchangeable back and bed section 26, one pair of two pairs .of links also pivotally connected to said fixed frame 3 and the other pair of said two pairsof links 2'! slot and pin connected to said fixed frame 3, and a second set of two pairs of links 40 and ill pivotally connected to said first pair .of links 31, one pair 4!! of said second set being also pivotally connected to one pair 25 of said first set and the other pair 4! of said second set being also pivotally connected .to the other pair 2] of said first set, all contributing to enable the interchangeable back and bed section 26 to aline with the first bed section 38 when said links 3'! and levers 38 are erect and said links 25 and 21 are .slightly inclined downwardly with the lower ends of the links 21 at the ends of the slots nearest to the links 31, see Figure l, and see Figs. 4 and 5, to enable the back section 2! when swinging into erect position out of horizontal position not to project beyond the rear edge of the frame elements 69, and the bed section in depressed position relative to the frame with the back section 2! in erect position when the links 25 and 2'! are substantially erect and the links 3'! and portions of the levers 38 are collapsed, see Fig. 5.
