12 Claims.

This invention relates to convertible furniture, particularly to a divan-bed article of furniture.

In our modern living conditions, it usually is necessary to effect a maximum utilization of a minimum amount of space. One way to effect such maximum utilization of space is by the use of convertible furniture, such as a divan-bed.

Different types of divan-beds have been suggested heretofore, all of which articles of furniture endeavor to provide a comfortable divan which can be readily and easily converted at any desired time into a bed and can thereafter be reconverted into a divan for interchangeable use of such piece of furniture. In such convertible furniture, the desired degree of comfort is frequently not realized, in either of the uses for the convertible piece of furniture. Also, some of such convertible furniture has been relatively compli cated in construction, or has been expensive, or it may have been objectionable for other reasons.

The general object of this invention is to provide a novel type of a divan-bed which is characterized by the comfort provided thereby when used either as a divan or as a bed.

Another object of the invention is to provide a relatively compact, sturdily constructed, inexpensive type of a divan-bed.

Yet another object of the invention is to provide a divan-bed wherein the bed is provided by the seat portion of the divan but with the bed having greater width than the divan.

Yet another object of the invention is to vary the height of the rear portion of an article of furniture when changing it from a divan to a bed.

Still another object of the invention is to utilize a rotatable support post for the rear portion of a divan-bed and to carry the rear part of the furniture support frame on such rear support post for varying the vertical positioning of the rear portion of the furniture frame with variation in use of the article of furniture;

The foregoing and other objects and advantages of the invention will be made more apparent as the specification proceeds.

In order to show the features of the invention,

one presently known form thereof is completely illustrated in the accompanying drawings, wherein:

Fig. 1 is an end elevation of a divan-bed embodying the principles of the invention, showing it in its divan arrangement and with the bed arrangement being partially indicated in broken lines on this drawing figure;

Fig. 2 is a front elevation of the divan-bed of Fig. l;

Fig. 3 is a plan of the divan-bed of Fig. l with the bed positioning ofthe divan back cushions being indicated;

Fig. 4 is a vertical section of the divan-bed of Fig. 1, taken on line 44 thereof, with the cushioning removed;

Fig. 5 is an enlarged fragmentary vertical section taken on line 5-5 of Fig. 4;

Fig. 6 is an end elevation of the frame shown in Fig. 4, with portions thereof being shown in vertical sections and with other portions thereof being broken away;

Fig. '7 is a fragmentary vertical section taken on line 'l--'! of Fig. 6;

Fig. 8 is a broken horizontal section taken on line 8-8 of Fig. 6 with the rear stop member ro tated to its down position;

Fig. 9 is a horizontal section taken on line 9-9 of Fig. 6; and

Fig. 10 is an enlarged vertical section through a modified type of a coupling between a rear support post and a sleeve carried thereby.

When referring to corresponding parts in the following specification, corresponding numerals will be used in both the specification and accompanying drawings to represent the same part whereby identification between such corresponding members is facilitated.

With reference to the details of the structure shown in the drawings, a divan-bed is indicated as a whole by the numeral ID. This divan-bed l0 usually includes an enclosure frame H which is positioned adjacent the lower portion of the article of furniture and which has any suitable supports provided therefor, such as one or more front leg supports [2 that are suitably secured to a portion of the enclosure frame H. The rear portion of the'enclosure frame II is shown as being supported by a pair of rear corner posts, or supports, or support members l3, which rear corner posts engage with the enclosure frame in a manner described hereinafter in detail.

The divan-bed It] includes a pair of rear cushions I4 and I5 that are carried by and supported from the rear corner posts [3. A conventional seat cushion l6 completes the supporting cushions of the invention and this cushion [6 will normally extend the length of the divan-bed It. The seat cushion I6 is usually supported by a box spring I? which in turn is carried on a frame l8. This frame i8 may be of substantially rectangular shape, as is the enclosure frame 1 I, and the front portion of this frame I8 is suitably supported on means, such as the enclosure frame I l or the front leg supports l2. In this instance,

, the frame It is secured to the enclosure frame I I by one or more hinges I9 to facilitate the vertical adjustment of the rear portion of the frame I8. as hereinafter described. There are no supports provided for the end portions of the frame I8 whereas the rear side or section of this frame IB is supported on the rear corner posts I3.

The principles embodied in the support of the rear portion of the frame I8 comprise one of the important features of the present invention by which the level of the seat cushion I6 is changed when used as a bed and as a divan. The rear corner posts I3, as indicated in Fig. 4, have suitable studs 20 in threaded engagement therewith with the heads of the studs extending therefrom. A sleeve 2| is telescopically and rotatably received by or engaged with each of the rear corner posts I3 and Fig. 5 shows that a substantially vertically but angularly inclined slot 22 is formed in each of the sleeves 2 I. These slots 22 each receive one of the studs 20 therein in order to provide certain limited but fixed relative movement between the sleeves and the support members provided therefor. In some instances, it may be desired to reverse the arrangement of the stud 20 and the slots 22 and in such instance the slot member could be provided in the rear corner post, while some protuberance could be provided in the bore of the sleeve 2| so that, if the sleeves 2| are held against rotary or arcuate movement. arcuate movement of the rear corner posts I3 will effect a vertical movement of the sleeve either upwardly, or downwardly, depending upon the particular correlation of the stud 20 and the slot 22 at such time.

Figs. 4 and 6 of the drawings show that usually some' kind of a stud, pin or protuberance 23 is secured to or formed integrally with each of the sleeves 2| and extends forwardly therefrom. These pins 23 engage with the rear portion of the frame I8 to support the frame on the sleeve. Likewise, the pins 23 retain the sleeves 2| against arcuate movement with the rear corner posts when such members are moved arcuately of the divan-bed I of the invention and insure the desired vertical movement of the frame I8.

Fig. 4 of the drawings shows the sleeves 2| supporting the rear portion of the frame I8. in its lowest position whereas Fig. 6 of the drawings illustrates the vertical position of the sleeve 2| and rear part of the frame I8 when the divanbed is positioned for use as a bed. At such time, it will be noted that the frame I8 is horizontally positioned wherea in Fig. 4, when adapted for use as a divan, th frame I8 slants appreciably downwardly of the divan-bed from front to rear thereof.

The rear portion of the enclosure frame II may be secured to the rear corner posts I3 by means of split collars 24 one of which is carried by each of the posts I3. Each of the collars 24 is provided with a circumferentially extending 'recess 25 that lies in a horizontal plane when the collar 24 is engaged with the post I3 and these recesses 25 receive therein studs 26 formed on each of the rear corner posts I3. Thus the collars 24 can b fixedly secured to the enclosure frame II and can be supported by the rear corner post but permit relative arcuate movement of the corner posts.

Each of the rear cushions I4 and I has a frame indicated generally by the numeral 21 provided therefor and with each such frame 21 having a plurality of plates or bars 28 secured thereto and also suitably secured, as by welding, to the rear corner posts I3 whereby the cushions are fixedly secured to and supported by such rear corner posts. The rear cushion frames 21 each have a bottom plate or board 28 provided therein.

In order to prevent undesired movement of the rear cushions I4 and I5 when positioned at either extremity of their arc of movement, a support arm 29 is pivotally secured to or otherwise carried on the enclosure frame I I at the rear thereof. This support arm 29 has a shoulder 30 formed on the upper surface thereof that engages the bottom plates 28, of the rear cushion frames 21 adjacent the free ends thereof. Support arm 29 also carries a pair of locking pins 3| which are resiliently urged up beyond the upper surfac of the shoulder 30 for releasable engagement with a hole 32 provided in each bottom plate 28 adjacent the free end thereof. Thus the rear cushions I4 and I5 can be fixedly positioned in their longitudinally extending positions, at which time the rear cushions I4 and I5 are longitudinally aligned and are adjacent but above the rear portion of the enclosure frame II. In some constructions, it may not be necessary to use the locking pins 3|, or some other type of a device could b provided for limiting rearward movement of the rear cushions I4 and I5 and preventing distortion or movement of same when one or more persons sits upon the divan-bed I0 and leans backwardly against a rear cushion. A similar support arm 33 is p votally secured to each end section of the enclosure frame II adjacent the front corner thereof. Thes support arms 33 each carry a locking pin or stud 34 that is urged outwardly or longitudinally of the support arm 33 by a coil spring 35 with which each such pin 34 is engaged. Fig. 7 best shows that the springs 35 may be positioned within a little compartment 36 that is secured to th free end of each support arm. The pins 34 are shown as having flanges 31 that engage with one end of the spring 35 and are urged outwardly of the compartment 36 thereby. Preferably a finger receiving loop 38 is provided at the exposed end of the pin 34 to make it easier to engage such pin for movement thereof. When the rear cushions I4 and I5 are positioned in their bed forming places, the pins 34 of the support arm 33 can extend through second holes 39 that are provided in the bottom plates 28 of the frames 21 and be releasably engaged therewith.

Fig. 10 of the drawings shows a slight modification of the invention wherein a rear corner post, or support H3, is provided and which carries a sleeve I2I thereon. This sleeve I2I has a suitable slot I 22 therein that extends angularly upwardly, or vertically of the sleeve I2I with relation to its longitudinal axis. The sleeve and support I|3 are secured to each other for a predetermined and limited amount of relative vertical movement therebetween by means of a stud I20 that is in threaded engagement with the support post H3 and with the enlarged head of the stud I20 having a bearing portion provided thereon that carries a suitabl roller bearing I30 or other bearing device thereon to facilitate a rolling or sliding movement of the stud I20 with relation to the slot I22 and sleeve I2I.

It will be realized that the vertically extending slots used in the sleeve members of the invention may be of any desired contour but that such slots should only be of in arcuate length. The ends of these slots may be substantially horizontally directed for short distances to provide end locks in the device of the invention.

The rear cushions I4 and I5 may be of any desired thickness and it will be appreciated that when used as a divan, the depth of the rear cushions l4 and I5 effectively reduce th seating depth of the divan-bed and provide a more comfortable seating action, particularly when taken in conjunction with the vertical movement of the seat cushion if of the clivan-bed. That is, the seat cushion it of the divan-bed is slanted downwardly of the articl of furniture when it is being used as a divan. However, when the rear cushions are swung to their positions adjacent the ends of the divan-bed, then the rear cushions l4 and I5 merely serve more or less as head and foot bOards of the resultant bed.

It will be noted that in some instances the frame l8 need not be provided and any spring means used to support the seat cushion l6 can be suitably supported by the front portion of the divan-bed and have the rear support means for such seat cushion l6 be engaged with and carried by the sleeve 2 I in any desired manner.

While one specific type of a rotatable support is shown for the seat portion of the bedframe, it will be realized that any other similar device may be used to support the rear of the seat of the divan-bed in a vertically adjustable manner. Henc one post could support the frame II and carry a second post that would support both the seat cushion I6 and the back cushions l4 and IS with the second post being rotatable and movabl vertically with relation to the first post. It may be desired to move the support posts through arcs as great as 180 in some instances although a 90 swing of the back cushions is usually all that is desired. When referring to the slot 22 being angularly vertically directed, it means that the slot 22 extends in, a direction having both axial and circumferential components. The slot 22 need not be either straight or be on an arc and may extend in a substantially axial direction in the center portion thereof.

In some instances, it may be preferred to have the corner posts positioned in different relation to the cushions that they support so that the entire length of the divan cushion H5 is available for use as a bed, when desired.

It will be noted that a novel combination furniture piece has been provided by the invention and that the objects thereof have been achieved.
