DAY BED Filed Dec, 4. 1922 sheets-sheet 2 Patented Dec. 24, 1929 UNITED STATES PATENT OFFICE CHARLES I-IULTGREN, OF CHICAGO, ILLINOIS, ASSIGNOR TO S. KARPEN & BROS., OF CHICAGO, ILLINOIS, A COREORATION OF VEST VIRGINIA DAY BED Application filed December 4, 1922.

This invention relates particularly to a type of furniture known as the day bed, but the construction is equally adapted for a davenport cr sofa bed. The principal objects of the invention are: to provide a construction of this kind which is solidly supported in open and in closed positions; to assist the overturning movement of the seat with a spring; to raise the seat from its closed position in overturning it so that the construction when folded will be close to the floor; to provide improved pivoting and overturning supports at the ends of the seat; and in general, to provide the construction herein shown and described.

In the accompanying drawings, Fig. 1 is a View with one end of the day bed removed, illustrating the preferred embodiment of my invention, the broken outline showing the seat in raised position; Fig. 2 is a similar view showing the seat overturned and the bed bottom extended; Fig. 3 is a sectional view showing one end of the day bed. Figure 4 is a broken view showing the position of the operating parts when the seat is closed; and Figure 5 is a view with parts broken away showing the seat in partially raised position.

In a day bed the two ends are unconnected above the seat at either side while a davenport or sofa bed has a back along one side either stationary or raisable, so that the'construction of the present invention is applicable to either type of furniture. It is desirable that the seat shall not be too high above the floor, that sufficient space is provided beneath the seat for accommodating the foldin bed construction, mattress and bed clothes, and that sutlicient space is afforded for upholstering the seat to make it soft and comfortable.

In carrying out the present invention, a pair ,of ends 1 are provided which may be made entirely of wood or may be frames covered or partially covered with upholstery, and beneath the two ends an upholstered'seat 2 is mounted for overturning movement. A metal frame 3 is provided at each end and it is preferably seated within the end 1 by recessing the inner side of the end or by making Serial No. 604,876.

it with projections 4 at the edges of the inner side of sufficient depth to receive the metal frame 3. This frame 3 may be permanently attached to the ends 1 but it is preferably made removable by means of bolts 5 projecting inwardly from the frame end 1 through the metal frame 3 and held in place by wing nuts 6. At one side of the sofa bed usually called the back, is a fixed base board 7 permanently attached to the metal frames 3 and corresponding in appearance to a front board 8 which is attached to the opposite side of the seat 2. Extending below the end frames 3 is a connecting strip 9 to assist in bracing them against movement apart. The front side covered by the front board 8 is usually left unbraced so that a supporting member is needed to strengthen the frames. If the front board 8 is broken or divided lengthwise, the lower portion of it is attached at the ends to the frames 3, to brace them, in accordance with well known practice.

The upholstery of the seat 2 is mounted upon a frame 10 of wood or meta-l so that the upholstered part can be built up of springs and fabric making a soft edge all around. Mounted on the underside of the seat is a bed bottom comprising a plurality of pivotally connected sections 11, 12 and 13. The bed bottom is connected to the seat frame by means of a fixed bracket 14 at each end of which the intermediate section 12 is pivoted and by means of a slotted guide 15 in which a headed pin 16 attached to one of the sections 11 is slidable. When these sec-tions are foldable under the seat they are held in place by a pivoted lock 17 attached to the front board 8, and when the sections are unfolded, as shown in Fig. 2, the outer sections 13 are supported by means of legs 18 pivotally connected at the outer side of each section 13, and connected by means of a link 19 with the pivot of brace 14, and each leg 18 being strengthened against lateral movement by a brace 20.

In mounting the seat for its overturning movement, apair of links 21 and 22 are connected to a pivot 21a at each end of the seat frame 10 adjacent the center thereof. One link 21 has a fixed pivotal connection 21b with the frame 3 or an extension 23 thereof, and the other link 22 is pivotally connected at its other end 22a to a lever 24, the lever being pivoted at 24a to the top cross piece of the frame 3 and having a. bent downwardly turned extremity 25 to which one end of a spring 26 is connected, the other end of the spring being connected to a fixed portion of the frame 3. Also connecting the seat 1 and the frame 3 is a link 27 pivotally connected to the frame 3 at 24a adjacent the center thereof and at 27a to the seat frame 10 between the pivotal connection of the links 21 and 22 therewith and the inner edge of the seat.

The links 21 and 22 normally rest in either open or closed portion of the seat on the upper cross piece of the frame 3, as shown by both of Figs 1 and 2. The links are preferably Vof double thickness, as shown in Fig. 3, made by folding a piece on a central fold line thus giving added strength and rigidity. In op'- eration the links 21 and 22 together with the lever 24 act-as swinging` bars for raising `the axis of the seat and thereby actually shifting the fulcrum upon which the seat is overturned. The result is that the seat normally lies as close'to the floor as possible, but it will and' balanced act-ion.

swing freely without touching the floor in overturning it, as the fulcrum is shifted upwardly beforefthe seat is inverted.

For limiting the movement of the seat in either direction, a projecting bracket 28 is attached to the seat frame which is adapted to engage a corresponding stop 29 attached to the end frame-3 in one position and to engage another stop 30, also attached to the frame' 3, in the overturning position, as shown in Fig. 2. This also takes some of the weight from the seat pivots, reducing the wear upon them.

In assembling this structure, the metal end frames 3, the links, and all the connect-ing parts are attached to the seat frame and the rear board 7 vand the under supports 9 are attached to the end frames entirely separate from the sofa bed ends 1. The structure thus described is entirely capable of complete action in overturning the seat without the attachment of the ends 1, and the ends can therefore be attached by simply inserting the bolts 5 through thecorresponding holes in metal end frames 3 and tightening the bolts in place. This can easily be done when the seat is in an intermediate position, asshown by the broken outline inr Fig. 2 whereuponthe construction will be ready for use.

If desired, the bed portion may simply cover the under side of the seat, making a narrow single bed without any folding 'sections. It will also be observed that for the overturning action, only the links 21 and 27 are absolutely necessary, the links 22, levers 2li, and springs 2G producing a more smooth Practically the same appearance of both sides is substantially the' same, and as the links 21 and 22 are resting on the upper edge of the frame 3there is no tendency whatever for theseat to tip on either side. In order to overturn the seat and eX- -tend the bed the lower edge of the front board 8 is grasped and raised upwardly which will' cause a toggle action of the links 24 and 22 raisingthe fulcrum of the seat, this action being assisted by the spring 26. lVhen raised to the uppermost position, as shown in the broken outline in' Fig. 2, the seat is easily overturned, the rear or lower edge swinging above and entirely clear of the floor until the underside of the seat lis-u-pper'most, with the links 21 and 22 again lowered and're'sting upon the upper cross piece Vof the end frame 3, as clearly shown in Fig. 2. In chang# ing from one position to the' other, thev guide link 27 is turned from the right handl side of its pivot (as shown in Fig.` 1) tothe oppof site side thereof when it assumestheinverted position. When the seat has been inverted,

lthe lock 17 is turned to release-the bed bottom sections from their connection therewith and the section 13 is folded. outwardly'.- This causes the central. section 12-to' swing upon its action takes place, the sections being first folded in the underside of the seat andthe seat being overturned by the fulcrum raising toggle action of the links 21 and 22 until the seat assumes the day bed position.

For shipping purposes the ends 1 can be easily detached from the seat and packed or crated with it thereby occupying' very little more space than the seat itself, thus commending the completed article of furniture from the manufacturers standpoint.
