SOFA-BED.

Specification of Letters Patent.

Patented May 3, 19 10.

Application led April 5, 1909. Serial No. 488,095.

To all whom 'it 'may concern:

Be it known that I, SOLOMON KARPEN, a citizen of the United States, residing at Chicago, in the county of Cook andl State of Illinois, have invented a new and useful Improvement in Sofa-Beds, of which the following is a specification.

My invention relates particularly to combination sofas and beds, or combination couches and beds, in which a foldable mattress frame is normally housed within the main frame beneath the seat of the sofa and equipped with a flexible bed-bottom, or wire mattress, the parts being so related as to afford ro'om between the sections of the folded mattress for the bed, that is, the mattresspad, bed-linen and covers.

My primary object is to provide an improved construction of the character indicated having the att rihutes of simplicity and durability and which is readily convertible from sofa-form to bed-form and vice versa.

It may be preliminarily stated that in the preferred construction of the invention, which is illustrated in the accompanying drawing, there are employed a main frame, a forwardly-swinging seat, a stationary back and a lfolded bed-frame normally housed within the main frame beneath said seat, the

seat serving as a medium 'for elevating andV extending the bed-frame when the seat is swung-to occupy a substantially horizontal position infront of the main frame. The seat is so linked to the front section of the bed-frame, or mattress-frame, as to be capable of dropping with relation to said frontsection when the bed is unfolded so that the seat structure will not interfere with the comfortable use of the bed. Ordinarily, the bed is secured to the mattress-frame before thestructure is folded into sofa-form, and the relation of the sections of the mattress-frame is suchv as to afford space for the not shown in the accompanying drawings.

In the accompanying drawings-Figure 1 represents a sectional view of my improved sofa-bed, with the mattress-frame, or bedframe, shown in the extended position; Fig.

2, a similar section showing the structure4 folded into sOfa-form; Fig. 43, a broken pers ective view showing a truss-member emp oyed as a part of the main-frame, upon the vertically-disposed arms of which the central section of the folding bed-frame, or mattress-frame, is pivotally mounted; and Fig. 4, a broken plan sectional view showing the structure in bed-form.

In the construction illustrated, A represents a main-frame; B, a stationary back supported by the end-standards of the mainframe; C, a folding bed-frame, or mattressframe; and D, a seat movably connected with the front-section of the bed-frame, beneath which the bedframe is normally housed when the structure is in sofa-form.

The frame A may be of any suitable construction. As shown, it comprises endstandards 1 which constitute the arms of the sofa; a rear counecti11g-member 2; a frontconnecting-member 3, which may be of Wood and which serves to connect the lower front portions of the end-standards; a bed-frame truss and standard 4 comprising a longitudinal channel-member 5 and arms or standards 6 rising from the ends thereof and secured by braces 7; and an angle-bar-S located adjacent to the channel-bar and havin its endportions connected, by braces 9, wit the uprights 6. The end-standards are equipped on their inner surfaces with lower stops' 10 and upper stops 11 which serve, respectively, to support the rear bed-frame section and the front bed-frame section when the bed is in the folded condition. p

The back B, when employed, may be connected with the end-standards 1 in any desii-ed manner. As shown, the back comprises a frame 12 which is rigidly connected with the end-standards b 'members 13; and an upholstered pad 14 shown in dotted lines) applied to the frame 12.

The bed-frame C, as illustrated, comprises a substantially U-shaped front section 15; a substantially U-shapedrear section 16; and an interm iate section 17 comprising endmembers which are joined by pivots 18 to the arms, or end-members, of the front section 15, and by pivots 19 to the arms,lor endmembers, of the section 16. The end-members of the intermediate section 17 have applied thereto blocks or brackets 20 whose lower ends eferring to the extended position of the ed) depend beneath said endmembers and are equipped with inwardlyextending pivots, studs, or bolts, 21, which are supported in eyes with which the up rights 6 are equipped at their upper ends. The mattress-frame, or bed-frame, has applied thereto a flexible bed-bottom, or wire mattress, 22. As shown, the end-members of the front and rear bed-frame sections are angle-bars and the end-members of the intermediate section 17 are angle-bars. 'Ihe arrangement is such that the horizontal flanges of the end-members of the section 17 rest upon the horizontal fianges of the endmembers of the sections 15 and 16 when the bed is in the extended position. If desired, stops 23 may be applied to the end-standards 1 to limit the forward swing of the 'intermediate bed-section 17. The rear portion of the rear bed-section 16 is connected, by links 24, with the lower rear corners of the endstandards 1.

The seat D comprises a frame 25 and an upholstered pad 26, which is shown in dotted lines. The front portion of the seatframe is connected, by links 27, with the end-members of the front bed-section 15. The rear portion ofthe seat is equipped with legs 28 having curved extensions 29 connected with the swinging edge of the front bedsection 15. The connections are made by means of pivots or studs 30 and 31, the stud 31 being adapted to work in a curved slot 32 in the curved extension 29. The curved extension 29 has an-extremity 33 provided with a shoulder adapted to engagea stud 34 with which the front bed-frame section 15 is equipped. In the unfolded condition of the structure, the seat is suspended at a distance beneath the `frame-section 15, while the legs 28 serve as supportsfor the outer or free edge of said section 15. In the sofa-form, the seat collapses with relation to the framesection 15 and is supported directly thereon,

- as shown in Fig. 2.. The links 27 fold to permit the-seat to 'approach the frame 15, and the legs 28 slide with relation to the studs 31, the projecting portions of the legs being practically hidden at the ends of the cushions of the seat and back, as will be `verted to sofa-form, the mattress understood from Fi 2.

The'operation wiIl be readily understood from the foregoing description. The bed is usually made up before thel structure is conroper, bed-linen and covers being secured 1n any suitable manner to the mattress-frame, so that when the mattress-frame is folded the bedding will be folded therewith.k The con= version is effected by swinging the seat D upwardly and rearwardly from the-position shown in Fig. 1 to the position shown in Fig. 2. In thisoperation the bed is foldedyand the seat collapses with relation to the section 15 of the mattress frame and rests thereon, the stops 1l serving to support the free edge of the front mattressframe section. As appears from Fig. 2, there is ample room afforded between the mattress-frame sections 15 and 16 to accommodate the bedding Iin folded condition. lVhen the conversion to bed-form is desired, this may be effected by swinging the seat upwardly and forwardly, thereby unfolding the bed and dropping the seat with relation to the frame-section 15. In the unfolding operation, the intermediate bed-section 17 is turned upon the pivots21, and the rear bed-section 16 is raised to the elevated position shown in Fig. 1. In the folding operation the intermediate bed-sec-4 t-ion 17' assumes the vertical position and the rear bed-section is lowered to rest upon the stops 10.- l The construction described is simple, durable, and may be manufacturedat a very moderate cost. In this construction itis to be observed, the intermediate bed-section 17v is pivotally supported upon the fixed or sta-` tionary truss 4; and in Vthe folding operation, the rear bed-section is lowered when the rear end of the intermediate section 17 swings downwardly,v and the rear bed-section is raised by a sort of cantaliver action, when the structure is converted to bed-form. The foregoing detailed description has y been given for clearness of understanding only, and no undue limitation is to be under- 95 stood therefrom, but the appended claims f are to be construed as broadly as is permissi'' ble in view of the prior art. lVhat I regard as new, and desire tose'- cure by Letters Iatent, is-
