2 Claims.

This invention relates to bed construction and more particularly to a folding sofa-bed comprising a piece of furniturehaving the appearance of a sofa by day and functioning as a double bed by night or when the occasion arises for the need of an extra bed. Prior to the instant invention it has been proposed that sofas be provided with folding springs and mattresses so that they may be unfolded to make up a, double bed, but such constructions have been relatively expensive to manufacture and thereby incapable of universal use, particularly by those who are in most need of such dual purposefurniture but cannot afford the very high cost of prior constructions.

Not only have prior constructions been relatively expensive to manufacture, but they have been objectionable because, of the fact that when the sofas are converted into beds, the temporary bed was too low'for the occupant and left the impression with the occupant that he or she was sleeping on the floor or very close thereto. This disadvantage will be'apparent when it is con sidered that sofa-beds are but temporary sleeping equipment and that the occupant has already been accustomed to sleeping in a bed of normal height.

It is an object of the instant invention to provide a piece of dual purpose furniture capable of being used for sitting in the day time and as a double bed at night, which-piece of furniture will be relatively inexpensive to manufacture and comfortable when used for either sitting or sleepmg. l

- It is a further object of the instant invention to provide a low cost mechanical sofa-bed of such construction'as to make up into a comfortable sofa in the day time and into a double bed of normal height in the night time.

Other objects and the nature and advantages of the invention will be apparent from the following description taken in conjunction. Withthe accompanying drawings, wherein:

Fig. 1 is a view in perspective of the sofa-bed in accordance with the invention in open position as a double bed;

Fig. 2 is a detail of the combined leg and hinge construction associated with the two sections of the double bed;

Fig. 3 is a detail of the rotatable support for the rear section of the double bed;

Fig. 4 is a transverse sectional view taken close to one end of the sofa, showing the bed sections in closed position in solid lines and the bed sections in partially open position in broken lines; and

- pearance thereto;

Fig. 5 isa view similar to Fig. 4 with parts of the sofa broken away and with the bed sections in fully opened position."

Referring to the drawings, the sofa-bed I0 may comprise a conventional frame ll, back 12, side arms I3,- and'in addition the'bed sections l4 and I5 which, when folded, make up the seat of the sofa as shown in Fig. 4.

i The bed sections and larin construction," with the exception that the section I5 may be a little wider than the section It as best shown in Fig. 4, wherein the front portion of the section I5 is shown to overlap the frame ll, whereas the corresponding portion of the section l4, when the said section is in, folded position, simplyabuts the frame ll. These sections 14 and I5 which make up the sofa seat as well'as the double bed, comprise an angle iron 7 frame Hi to which may be attached wooden pieces H to facilitate the securing thereto of the outer fabric or other material that the upholsterer may use for this purpose. This angle iron frame supports a crisscross arrangement of wire H! which in turn supports a plurality of coil springs I9.

These coils l9 are tied together at their upper ends by aplurality of very small helical springs and the entire assembly is framed at' the upper portions of'the outer coil springs [9 by a wire margin whereby a complete spring unit is formed. The fabric 20 and stuffing 2| complete the bed section assemblies and give a comfortable ap- In Fig. 3. the sofa is shown with the bed sections in closed position and the parts arranged for sitting purposes. Removable pillows, not

shown, may be associated with the top of thebed section' [5, if desired, or they may be dispensed with as the bed section l5 by itself is quite comfortable. The twosections l4 and I5 are supported within the sofa-bed lll,'when the sections are in closed position, by the bolt 22 and the right angle element 23', one endof which is secured to the bed section l4 and the other end of which is pivotally secured to the frame of the sofa l0. Secured to the angle iron frame of section I4 is a pair of metal extensions 24 which may cooperate with corresponding extensions from the frame of the sofa when the sections .are in closed position so that the said sections may besupported at the rear thereof. It is to be understood that it is within the spirit of the invention to utilize other stop means for supporting the sections when in closed position, which stop means may be simply a frame member positoned beneath the section 14 or otherwise in IS are generally simi-' eration will effect pivotal action about the bolt 22 as also is shown in the broken lines in Fig. 4. Continued rotation of the element 23 about the bolt 22 and a straight horizontal pulling action on the front of the bed section I5 will bring the bed sections to the positions shown in Fig. 5. r

The combined legs and double pintled hinges 25 will automatically take the positions shown in Figs. 1 and 5 and the front legs 26' 'may 'be straightened to the positions shown in Figs. 1 and 5. The bed section l5 may be provided with: strips at its front and rear, if desired, to facilitate the opening and closing ,of the sofa bed II]. In order to make the construction sturdy andyet as inexpensive as possible, the legs 25 are of the proper length to support the sections l4 and I5 at comfortablebed height, as indicated in Figs. 4 and 5, and the upper portions thereof are associated with the adjacent corners of the angle iron frame It of the sections I4 and I5 by a pair of pintles 2'! and 28, see Figs. 2 and 5,, whichmay simply comprise loose fitting rivets orother suitable pintle elements. The legs 26 are pivotally secured at their upper portions 29 to;.the front part of the angle iron frame I6 of the section 15, whereby when it is desired to convert 1:

the bed sections into a seat for the sofa, the legs 26* may be rotated in a direction toward each other to a position within the angle iron making up the front part of the frame l6 for the section l5. It will be noted that the legs 25 automatically take care of themselves and when the bed sections I4 and [5 are closed, the legs 25 fit therein. This feature isperhaps best illustrated by the broken lines in Fig. 4.

In order to ensure that the bed sections will be in the proper sitting position when the sofa-.

bed I!) is'closed and in the proper sleeping positionat bed height when the sections I4 and I5 are opened, and in order that the mechanism ensuring such operation may be fabricated inexpensively without sacrifice of smoothness of operation, the bolt 22 is provided with a washer 30 which engages one side of the vertical leg 231) of the. right angle element 23. Between the other side of the vertical leg 23v and. the frame H is a helical spring 3| which serves as a bushing and spacerelement 3! for the rotating right angle element 23. The bolt 22 extends through the frame II and is provided at its other end with a washer 32 and a nut 33. The horizontal leg 2371. is secured to the frame 16 of the section l5 as already described.

It will now be understood that the construction set forth above permits of fabrication at low cost and that the resultant sofa-bed will be comfortable for both sitting and sleeping purposes. It will be noted that the simplest materials have been utilized and that no separate mattress is necessary for association with the bed sections l4 and I5 which are already upholstered for both sitting and sleeping purposes. The particular frame construction for the bed sections and the novel and inexpensive legs associated therewith are factors in keeping the cost of the construction at a minimum. The novel construction which permits the bed sections to be stowed 'away in the sofa-bed when the same is to be used for sitting purposes and effects the arrangement or the bed sections at a bed height level when the sofa-bed is to be used for sleeping purposes is particularly advantageous and makes for the great comfort of the user.

It will be obvious to those skilled in the art that various changes may be made in this device without departing from the spirit of the invention and thereforethe invention is not limited to what is shown in the drawings and described in the specification but only as indicated in the appended claims.

What is claimed is:

11. In a sofa-bed having a common section utilized as a bed portion when the sofa bed is used. as a bedand utilized as a seat when the sofa-bed is used as a. sofa and the construction being such that the said common section is at relatively higher bed height level when the sofabed is used as a bed andat relatively lower seat level when the sofa-bed is used asa sofa comprising: a frame, a first bed section and a second upholstered innerspring'combined seat andbed section, said sections being secured together in foldable relation and in such. manner that the said second section is on top when the sections are folded by moving the second section toward the first section in a first rotary direction, an extension elementpivotally secured to said frame and fixed to: said first section, so that said first section may be swung relative to said frame in the opposite rotary direction, the pivot. point being locatedon the frame at such distance from the bottom thereof, and the length of the extension element and the height of the upholstered second section each being such that when the foldable sections arein open bed position, the top of the second section is at bed height, which is higher than the level of the second section when the twosections are folded together in the frame.
