2 Claims.

This invention has to do with that type of furniture known as convertible seat beds and more particularly to what is sometimes called a love seat, by which is meant a sofa having the appearance of a davenport but much shorter and usually just long enough, like a Pullman car seat, to accommodate a seated couple and, therefore, much too short to be used as a comfortable bed, it ordinarily having a length about equal to the width of a full-size bed, which is about 54".

The object of the present invention is to provide a love or Pullman seat type sofa having the usual upholstered seat, back and arms but which may be readily and easily converted into e, fulllength bed with a full-sized mattress in length, Width and depth or thickness as compared with this type of furniture now on the market, and requiring no separate handling of the mattress, and which is simple and durable in construction and economical to manufacture.

As is well known both to manufacturers and users, convertible upholstered sofa-davenports or other structures of this type usually present an attractive appearance as an article of furniture and useful to sit upon but when converted into a bed, have little to recommend them for sleeping qualities because of the impracticability of providing them with comfortable mattresses. Aside from this, in order to convert them from one type to another requires considerable work in the removal and replacement of the mattresses or the lifting of heavy sections, the depth of the seat usually limiting the width of the structure when converted into a bed so that many unsuccessful attempts have been made to overcome these disadvantages or else they are so expensive that they are not within the means of the average householder.

As is also well known, a full-length davenport is too large an article of furniture for the average department room today, giving it a crowded appearance. Therefore, it has become necessary to shorten it, thus providing What is called a love seat which, however, is toc short fo-r a fulllength bed.

The present improvement which I have designated a Pullman bed, while having only the usual length of such seat, nevertheless is so constructed that it may be readily converted into a full-length bed transversely of the seat or back and having the width of a full-sized bed with comfortable inner spring mattresses of the proper thickness for comfort, and which requires no special handling, displacement or removal of the mattresses to convert the article from a seatto a bed or vice-versa and, therefore, I believe I have provided the most practicable and easily handled low-cost convertible seat-bed that has ever been placed upon the market.

In the drawings accompanying and forming a part of this specincation,

Fig. 1 is a perspective view of this improvement in the form of a love seat.

Fig. 2 is a perspective View thereof in the form of a full-length and width bed, the two illustrations being somewhat foreshortened to enable them to be placed upon the same sheet of drawings.

Fig. 3 is a transverse sectional view of this convertible seat-bed illustrating the spring mattress sections partly pulled forward from under the back.

Fig. 4 is also a transverse sectional view of this convertible seat-bed illustrating the spring mattress sections fully pulled forward from under the back with the sections raised and the swinging top section in position to form a full-length double bed, the dotted lines illustrating the swinging section in upright position.

Figs. 5 and 6 are detail views of the automatic latch or lock for maintaining the structure in bed position, Fig. 6 being a section of Fig. 5 looking in the direction of the arrows in Fig. 5.

Similar reference characters indicate corresponding parts in the several views.

Before explaining in detail the present improvement and its mode of operation, I desire it understood that the invention is not limited to the details of construction and arrangement of parts illustrated in the accompanying drawings since the invention is capable of other embodiments, and that the phraseolcgy employed is for the purpose of description and not of limitation.

The love seat shown in Figs. 1 and 2 comprises a suitable framework or main frame having a back and a pair of arms, usually upholstered, and which framework is provided with legs having V casters if desired.

Since, in order to form a bed transversely of the seat or back, the two mattress sections, when extended, must be over six feet in length, it follows that, when folded, one upon the other, each section would be more than 36" long which would be much too great a depth for a comfortable seat and would present an unwieldy appearance, therefore, the back 2, in the present instance, is shortened in its height to provide a space 3 into ywhich the inner ends of the spring mattress sections extend When the structure is in the form of a seat, thus giving the proper depth to the seat (see Fig. 1).

To transfer the structure into a double bed, these sections are first slid forward to free the inner ends thereof from the back and then the top or outer section is swung over to form a full length double bed (see Fig. 2) and since the width of the sections from arm to arm is about 53" to form the ordinary love seat and as this is usually the width of a fullesize bed, it follows that th'e structure thus provides a full-width and fulllength bed for sleeping purposes. Not only this, but the stuffed mattresses A and B of full height or depth, usually provided with inner springs, are carried permanently in position, one, as A, on top of the inner or lower spring mattress section 4 and the other, as B, under the topof the swinging or upper or outer spring mattress section 5 when th'e two are folded and thus are always. in position when the structure is extended, without any separate handling thereof. VrIhe top side of the upper 'or' swinging spring -top section 5 is provided with the usual upholstered seat or cushion C' conforming to the style vof the back.

As the top vor upper section 5 is swung outward and over to form the full-length bed, th'e 'connections are such that the lower section issirnultaneously and automatically raised to bed VVheight and, of course, lowered to `give seat height when ,the upper section is folded upon Ythe lower section.

In the preferred'form herein shown. and vdescribed, in addition t'o the usual framework hereinbefore referred to, th'e structure comprises two spring mattress sections 4 and 5 preferably made of suitable angle irons;r the end irons of which are suitably connected by lengthwise extending bars. Each has a suitable spring or `link fabric carrying, as before stated, the .usual stuffed 'mattresses A and B, the upper mattress -B'usually being so `connected with the link fabric that it will not be displaced vduring the swinging movement of the yupper section 5.

These'two spring mattress lsections Il and 5 `are link or lever connected for simultaneous sliding movement and topermit the topor upper section-5 -to lbeY swung -over from. its seat position to -bedposit-ion, the lower section 4 is connected with' a sliding under frame 6 having rolls 1 traveling on .tracks -8 .formed by angle iron cross end bars fixed to the ends of the/.main frame. 1

This forward sliding -movement is, however, a limited oneand, as shown in Fig. 4, is onlysubs'tan'tially equal tothe depth of the back 2 so that even when the bedis open or extended, it takes up much less space in the room than would be the f casei'f the mattress sections had to be sh'iftedto the front .edge'of the supporting frame before they could be swung open. As the 'twomattress sections are slid out only substantially the 'depth of the back, and vthen only after this partial sliding movement swungopen, it 4follows that the bed, even when extended, takesup much 'less room space than many forms of lfolding bedsfyet it is a full-length and full-width bed made -upof but -two spring mattress sections Ywhile the seat still vhas the proper depth, usuallya'bout 22" to sit upon in comfort. Attempts to swing the mattress sections open without this .partial sliding .fmovement have .only .resulted .in .impractical cumbersome structures. This .partial sliding movement is `limited iin any suitable way -as by havingY the4 rolls, 'such as the yrear rolls YV'I of rthe underslung frame yengage rany suitable projection or stop which' maybe in the form of a lguide roll carried by the angle bars ortrack v8. This sliding under frame 6 has its cross end bars 9 carrying the rolls 'l suitably connected by lengthwise extending bars Iii. Pivoted to these cross bars 9, as at I2 at each end of the bed, is a pair of links or levers I3 and i4, each having a pin or roll I5 and I6 moving in slots I'I and I8 of the ends of the mattress section A. The opposite ends of these levers I3 and I4 are forwardly bent or curved and are connected, by a link ISI to which is pivotally connected va raising and lowering lever 25, the opposite end of which is pivotally connected to a T-shaped plate or iron 2l secured to and forming a part of the top or upper swinging mattress section 5 and located at the inner side thereof when the section is extended. This iron 2I is also pivotally connected to a bar v 2'2 .fixed to the front of the lower section 4.

The lever Ie is extended to form a supporting leg M having a roller or caster I to support the mattress section 5 when extended into a bed approximately midway thereof and it will be observed that while this leg supports the two mattress sections substantially midway of their width, the linkage connection through the Inedium of the links 20, 2l and 22 supports vthe Icuter bed section at .its front by suspension.

As before stated, the upper side of the top o r swinging spring mattress section 5 is vupholstered or provided with a seat cushion C' to form the seat.

From `the foregoing, it will be seen that, without th'e lremoval of the seat C or of the two stuffed mattresses A and B, the sections may first be slid forward a sufficient distance to clear the lower edge of the back 2 and then the seat or uppersection -5 may be readily thrown over into position to extend the lower section and thus form ks, full length bed. At this time, a folding `leg '24, link connected as Aat 25 by a pin and slot connection with the leg, is shifted or thrown Vinto position to support .the outer end of the .bed vsection 5, this foot being folded up when the reversal of this operation takes place to foldtheouter section 5 on top of the lower section Il. The front legs of the swinging section 5 have a dog or catch 24 for preventing collapse of the ,legs and are .released and fall into position by gravity.

To facilitate manipulation of the structure and render it easy to operate, the 'link or lever I3 has attached thereto a pair of coiled springs 26 connected at one endY to an extension or upwardly bent lend. v25 of the Vlink I3 while at the other end they are connectedv to a rigid .lug ZB carried by the main frame.

To this 4lug 2S" alink .35 is pivoted, the opposite end of 4which is pivoted yto the under side of the section 4 as Aat 36. Connecting the two links or levers I3 is a lengthwise extending'cross bar 31 and, also, -to these levers I3 are attached coiled vsprings .38, the opposite ends being con* nected to a cross bar i0 ,of the sliding under frame .6. Stops 35 are secured to the tracks .3 -(see Figs. 4, 5 and "6) which, when the rbed sections 4 and ,5 are slid out, :are engaged by the ends of pivoted latches @il carried by upstanding arms .4I secured to the roll carrying bars 9 `and serve `to prevent the bed sections Il and IE from being ,prematurely slid back. :This latch works automatically for,when the top bed Vsection 5 is :folded Vover on'the 'bcttorn bed section @and the two sections are lowered into seat position, a projection 42 von the lever i3 strikes the end 43 of the .latch yand disengages it fromA the stop Y to permit the bed sectionsi and 5 to .slide .backwardintoplace under vthe back;2.

Since the two bed sections 4 and 5 are spaced apart a suitable distance necessary to provide for'the superposed stuffed mattresses A and B, it follows that when arranged as a sofa or seat, it is necessary, in order to provide an attractive appearance to the front of the seat comprising the front edges of the mattress sections 4 and 5 and the stuffed mattresses carried thereby, that they be covered and, for this purpose, I have provided a panel 2l, upholstered if preferred, which is so connected with the mattress sections 4 and 5 that it will automatically position itself to accomplish this purpose.

As shown, this panel 2i is link connected as at 28 and 29 to the mattress sections 4 and 5. Consequently, when the upper or tcp section is thrown over into bed position, this panel automatically assumes the suspended position shown in Fig. 4 below the two sections but, when the two .sections are folded, one uponthe other, it automatically assumes the vertical position shown in. Fig. 3. As shown, it is of' substantially U- shape so as to overlap the outer edges of the link fabric mattress sections l and 5. As will be seen in Fig. 4, the panel 2l is hinged to the under sides of both spring mattress sections d and 5 so that it is suspended in a substantially horizontal position when the sections are eX- tended but when the spring mattress sections are closed, as in Fig. 3, the hinged connection of this panel is at the top side of the top spring mattress section 4 and at the under side of the bottom spring mattress section Y5` Thus, when the structure is in the form of a love or Pullman seat, it is rst merely necessary to pull or slide the two spring mattress sections together forward to free them from under the back, then swing over the top section 5 to form a full length bed with the stuied mattress sections A and B in position for use. During this swinging movement, the lower section `li, through the medium of the linkage connections hereinbefore described, is automatically raised to bed height so that the two sections will be level at such height. When it is desired to convert the bed into a seat, it is merely necessary to swing the top or outer section 5 upon the lower section, thereby lowering the two sections 4 and 5 into scat position and permit the saine to be slid back with their rear edges under the back 2 whereby, as stated, the structure is then in seat height position.

It will be observed that when the top or upper mattress section 5 is swung into bed position, the opposed lengthwise edges thereof are in juxtaposition, the structure being so proportioned as to accomplish this and, in practice, since it is desirable to prevent a space between the adjoining stuifed mattress sections A and B, these two stuffed mattresses are flexibly connected together and, for this purpose, they are hinged together to form a continuous sleeping surface when the structure is extended to form a bed. This also assists in maintaining the position of the stuied mattresses on the spring fabrics, preventing movement of one away from the other as well as eliminating any space therebetween and providing, as stated, a continuous comfortable mattress to sleep upon.

From the foregoing, it will be seen that one of the great advantages of the present improvement is that, instead of sleeping, as is usually necessary, lengthwise of the seat, the structure permits one or two sleepers to rest crosswise of the seat while, at the same time, the seat is very much shorter than the ordinary davenport and obviously, since there are many advantages resulting from the construction of the present improvement, the same operating mechanism could, if desired, be used with other forms of furniture to make single, double, or even triplewidth beds by merely shortening or lengthening the seats.

Furthermore, it will be observed that this improved bed is so simply constructed that the entire bed structure comprising the two spring mattress sections and the sliding under frame 6 may, as a whole, be readily withdrawn from the main frame comprising the back and the ends or assembled therewith in a simple and expeditious manner whenever this is desired.

It is to be understood that, by describing in detail herein any particular form, structure or arrangement, it is not intended to limit the invention beyond the terms of the several claims or the requirements of the prior art.

It will be understood, of course, that the upholstered seat C may be replaced by separate cushions if desired and also some suitable means may be provided to prevent the seat section from moving forward on its rolls when the structure is in the form of a sofa. A simple means for this purpose may consist of a spring catch or merely a pivoted latch button which may be secured to the inner side of the part 21 so that when the seat is pushed into place under the back, turning of this button will engage the inner end of the xed arm frame and thus keep the seat from inadvertently sliding forward when the user reclines against the back 2.

Having thus explained the nature of my said invention and described a way of constructing and using the same although without attempting to set forth all of the forms in which it may be made or all of the modes of its usefI claim:
