Specification of Letters Patent.

PatentedMar. I, 1910.

Application filed June 1, 1909. Serial No. 489,572.

Improvement in Sofa-Beds, of which the following is a specification.

My invention relates particularly tocombination sofas and beds, or combination couches and beds, in which a foldable mattress-frame, or foldable bed-frame, is normally housed within the main. frame beneath the seat of the sofaand equip ed with a foldable' wire mattress, or flexi le bedbottom, the parts being so related as to afford room between the sections of the folded bed-frame and bottom for the bedding, 2'. a, the mattress pad, bed linen and covers.

My primary object is to provide an improved construction of the character lll Cllcated possessing the qualities of simplic ty, durability and handiness of operation, while adording a comfortable sofa of pleasing appearance when in the sofa form and a thoroughly comfortable bed when in the bed form.

lhe present invention constitutes a modification of an improvement on the invention disclosed and broadly claimed in my application No. 485,973, filed March 26, 1909.

It may be preliminarily stated that in the preferred construction of the invention which is illustrated in the accompanying drawings there are employed a main frame; a stationary back carried thereby; a seat mounted to swing rearwardly and assume a standing position adjacent to the back; a forwardly shiftable carriage normally housed in the main frame when the struc-. ture is in sofa form; and a folding bed mounted on said carriage and shiftable forwardly therewith with relation to the main frame, said folded bed comprising a front bed-section pivotally joined to the front upper portion of said carriage, a normally depressed rear bed'section having its end members forming guides, or equipped with guides, and slides connected with said guides and carried by links mounted on said carriage, said slides and links connected with the front bed-section, whereby, when the front bed-section is swung forwardly to the open position said links will be swung and thereby elevate said slides, the slides at the same time moving on the guides of the rear bed-section and serving to'elevate the same to the level of the front bed-section. As has been indicated, the mattress-frame, or foldmg bed, is preferably equipped with a flex- 1b e mattress, or bed-bottom, which is unfolded; orspread in the operative position when the device is converted to bed form; I

and the mattress-pad, or mattress proper, and other bedding, including: the bed linen and covers, are secured in position and folded between the sections of the foldable mattress-frame, so that the bedding will be spread out with the mattress, or flexible bedbottom, when the device is converted to bed form.

lln the drawings-Figure 1 represents a sectional view of my im roved combined sofaand bed, taken! as inchcated at line 1 of Fig. 3, and illustrating the device in unfolded condition, that is in bed form, the flexible bed-bottom and bedding not being shown in this View, however; Fig. 2, a simllar section showing the device in sofa form; Fig. 3, a horizontal section taken as indicated at line 3 of Fig. I; Fig. 49,. a broken plan view showing the connections between the front and rear bedsections and oneof the front corners of the carriage; Fi 5, a broken vertical section taken as indicated at. line 5 of Fig. 4:, and showing a connectionbetween one of the slides which carries the rear bedsection and one of the links supporting said slide; Fig. 6, a broken vertical sectional view taken as indicated at line 6 of Fig. 1 and showing a connection between the front bedsection and the carriage; Fig. 7, a broken vertical sectional view taken as indicated at line? of Fig.1; Fig. 8-, a broken vertical section taken as indicated at line 8 of Fig. 1; Fig. 9, a broken vertical sectional view illustrating the front portion of the carriage and showing a modified form of connection between the front extremities of the end members of the rear bed-section and the front portion of the carriage; and Fig. 10,;1 broken horizontal sectional view taken as indicated at line 10 of Fig. 9.

in the preferred construction, A represents the main frame; B, a sofa-back fixedly secured between the end-standards thereof; C, a swinging sofa-seat adapted to assume a standing position adjacent the back; D, a forwardly and reaiava-rdly movable carriage mounted on the main frame; and E, a folding bed mounted on the carriage D. The frame A may be of any suitable conloo lltl

struction. In the construction illustrated, the frame comprises wooden end-standards 1 which constitute the arms of the sofa and which may be made as ornamental as desired; a rear connecting member 2; and a bottom connecting member 3 which joins the end-standards near their front portions. As shown, the end-standards l are equipped on their inner surfaces at their lower portions with channel-bar tracks 4, which are carried by brackets 5 at their ends.

The back B may be attached in any preferred manner. As shown, it fits between the end-standards 1 and is ri idly connected therewith by angle-bars 6. he back preferably inclines rearwardly slightly, as shown. Ordinarily, the back comprises a frame 7 equipped with an upholstered pad 8, which is shown by dotted lines.

The seat C may be of any preferred construction. As shown, it comprises a springsupporting frame 9 which usually is equipped with an upholstered pad 10, shown by dotted lines. The rear portion of the seat is linked to the main frame, the connection being made by means of links 11 whose ends are joined, by pivots 12, to clips 13 and 14, carried, respectively, by the end-standards 1 of the main frame and the end pieces of the seat-frame 9. The rear, or inner edge portion, of the seat is preferably pivotally joined to the rear portion of the carriage D. As shown, the connection is made by means of arms 15 which are rigidly attached to the end members of the seat frame 9 and have their extremities joined, by pivots 16, to the clips or brackets 17 with which the end members of the carriage D are equipped at their rear upper corners. The pivotal, or hinged, connections may be of any desired form.

The carriage D, in the form illustrated, comprises a pair of rectangular frames, or slides, 18 mounted on the tracks, or runways, 4; a rear connecting member 19 joining the rear lower corners of the slidable frames 18; and a front truss member 20 which connects the front lower corners of the slidable frames 18, the end portions of the member 20 being joined, by braces 21, to the upper front corner portions of the members 18. Casters 22 support the front portion of the carriage through the medium of the truss member 20; and casters, or rollers. 23 support the rear portion of the carriage on the tracks of runways 4. The main frame is also preferably provided with casters 24, for convenience in moving the article of furniture, as a whole, about the room.- The carriage D carries a movable frontpieces 25 which serves asa front piece for the sofa beneath the seat C when the structure is in sofa form, and which moves forward with the carriage when the seat is raised to the standing position and is automatically swung downwardly out of the way of the bed when the bed is unfolded, the operation of swingingsaid front piece dowmvardly being performed by links 26 which are pivotally connected with" said front piece and with the front section of the bed. The lower portion of the front piece 25 is preferably connected with the cross member 20 of the carriage by means of hinges 27. The carriage is equipped at its front corners with uprights, or standards, 28, 28 which form guides for the front extremities of the end members of the rear bed section. The members 28 are preferably in the form of channel-bars with their flanges turned. toward the end-standards 1' of the main frame. Said members 28 have their lower ends connected with the end portions of the member 20 and have their upper portions connected, by brackets 29, with the braces 21.

The folding bed E preferably comprises a U-formed rear bed-seotion, or mattressframe section, 30 whose end members 31 are carried by slides 32 mounted on parallel links 33 carried by the end frames 18 of the carriage D; a U-shaped front bed-section, or mattress-frame section, 34 whose end members 35 are connected, by pivots 36, with the end frames 18 of the carriage; links 37 having their front ends connected, by pivots 38, with the end members 35 of the front mattress-frame section, and having their rear ends connected, by pivots 39 (see Figs. 4 and 5), with the, upper ends of the front links 33 and the front ends of the slides 32; legs 40 pivotally connected with the end members 35 of the front bed-section and adapted to fold alongside said end members when the bed is folded; and a wire fabric, or flexible bed-bottom, 41 connected with the front and rear mattress-frame section and adapted to fold therewith. A loop, or handle-device. 42 embraces the section 34 and is provided for the purpose of affording convenient means for swinging the front bedsection forwardly about the pivots 36 from the folded position.

According to the preferred C(mstruction, the end members 31 of the rear mattressframe section are of T-shaped cross-section, upon the vertical flanges of which the slides 32 are folded and to the horizontal flanges of which the bottom fabric 41 is attached. This will be readily understood by reference to Figs. 4 and 5. The front extremities of the horizontal flanges of the end members 31 are provided with notches, or guide-grooves, 43, which, as shown in Fig. 4, engage the rearmost upturned flanges of the standards, or guide-members, 28located near the front corners of the carriage. The extremities of the members 31 lie outside the standards, or guides, 28, so that the standards 28 serve effectually to prevent the extremities of the rear matt-ressframe section from being drawn toward each other when the bed is occupied and the actual bed-bottom under tension. The upper ends ofthe rear links 33 are joined by pivots 44 (shown in dotted 5 lines in Fig. 1), to the rear ends of the slides 32. The lower ends of both pairs of links 33 are joined to the bottom port-ions of the end-frame 18 of the carria eby pivots 45, the connections being made through the medium of bars 46 applied to the lower portions of said end-frames, as shown in Fig. 1. The'lowcr ends of the rear pair of links 33 have extensions 47 which project beneath the pivots .45'and engage the front ends of the tracks 4 when the bed is in the open conditionshown in Fig. 1, thereby locking the carriage against rearward movement with relation to the main frame, so that it will be impossible to lower the seat C when the bed isin the open condition.

The form of the pivots 36 is best shown in Fig. 6, from which it will be understood that each pivot comprises a bolt having a shank 48 extending through the end-frame l8 and the vertical portion of the brace 21, a spacing collar 49 adapted to space the extremities of the end member of the front mattress-frame section with relation to the end frame 18, and a nut- 50 applied to the bolt, 3 the extremity of the end member 35 being confined between said nut and collar. As thus described, there is afforded a space 51 adapted to accommodate the link 37. The link 37 is provided at its lower edge with a 5 notch or recess 52, affording a shoulder 53 adapted to engage the pivot-bolt 36 (or its collar 49) and lock the bed in its unfolded position. This feature is not an essential, inasmuch as the links 37 occupy a substantially horizontal position when the bed is unfolded and the pivots 36 are preferably somewhat above the horizontal plane in which the

pivots

38, 38, which connect the front ends of the links 37 with the end members 35 ofthefront mattress-frame section, lie. The pivots 38 also serve, as before stated, to connect the adjacent extremities of the links 26 to the front mattress-frame section. I have shown the front extremities of the end members 31 of the rear mattress-frame section equipped with lugs 55 to-which are attached springs 56 whose rear ends are connected by lugs 57 carried by the slides 32. 55 These springs aid in drawing the slides 32 forwardly in the operation of unfolding the bed, and hence aid in swinging the links 33 upwardly and elevating the slides 32 upon which the rear..mattress-frame section is 0 mounted.

The operation will be readily understood from the foregoing description. Assuming the structure to be in the sofa form, as illustrated in Fig. 2, the seat may beswung to a standing position, in which operation, by

reason of the relation of the links 11 and hinges 1-5, the carriage D will be moved forwardly with relation to the main frame. In this opera-tion, the front piece 25 of the sofa moves forward with the carriage. The operator may then swing the front bed-section forward y about the pivots 36, in which operation the links 37 will daw the slides 32 forwardly and turn the it links 33 to a been properly made up before the structure was folded into sofa form, the bedding will be spread out when the bed is unfolded in the manner just described. Prior to the operlition of converting to sofa. form, the bedis made up and the bedding secured tothe mattress-frame. The bed is then folded, the rear section at the same time dropping so as to lie a sufficient distance below the superposed front section to afford am le space for the bedding in the folded condition thereof. After the bed has been folded, the seat C, which becomes released when the bed is folded, may be swung to the horizontal 10o position, in which operation the carriage will be automatically retracted. In the operation of folding the bed, prior to the re traction of the carriage, the front piece 25 is automatically swung to the vertical position, so that when the carriage is retracted the front piece serves as a front piece for the sofa and to hide the bed which is normally housed beneath the sofa seat.

While it is preferred to employ the links 11 to automatically shift the bed, as a whole,

changes; an the corresponding parts are similarly ide -'fied by numerals,- and the changes will now be described. Instead of employing the channel-form vertical guide member 28 and notching the front extremity of the end member 31' to the rear mat tress-frame section to engage therewith, I

employ, inthe modification, a guide-plate 58 which is secured to the front portion of the end frame 18 and equi ed with a vertical guide-slot 59in WhIC slides a bolt 60 carried by the extremityof the end member 31 of the rear mattress frame section. The extremity of the member 31,.a-sshown in Fig. 10, is spaced with relationto the guideplate 58 by a sleeve 61. located between the end member 31 and said guide-plate. The front upright of the end frame 18 is provided with a slot 62 which accommodates the head of the bolt 60 in its vertical'movement. It will benoted that the bolt 60 is equipped with a nut 63, and thus the front extremities of the end members 31 of the rear mattress-frame section are prevented from springing toward each other when the bed is occupied. While the modified form of guide-sections between the front extremities of the end members of the rear mattressframe section and the front portions of the end frames of the carriage "is a desirable form, the form previously explained ispreferred, because 1t can be more cheaply constructed and will nevertheless prove entirely satisfactory in ,use.

Thev foregoing detailed description has been given for clearness of understanding only, and no undue limitation is to be understood therefrom, but the appended claims are to be construed as broadly as permissible in view of the prior art.
