SOFA-BED.

Specification of Letters Patent.

Patented Mar.' 2l, 1911.

To all whom 'it may concern: l

Be it known that I, SoLoMoN Kuren', a citizen of the United States, residing at Chicago, in the county ofCoolf and State of 1llinois',-have invented a new anduseful Improvement in Sofadeds, of which the following is a specification.

invention relates particularly to combination sofas and beds, in whieh a foldable mattress-frame is normally housed Within the main frame beneath the seat of the sofa vand equipped with afoldable bed-bottom,

tion is provide a simple construction ofY or wire mattress the parts being so related as to afford room between the sections of t-he'fol'ded bed for' the bedding, z'. e., the mattress proper, bed-1inen 'and covers.

The primary object of the present inven- 'oombined sofa and bed which may be comortubly employed either as a sofa or a bed,

sind which can be manufactured at very to be' unfolded in the operation-of swinging the seat to the inverted'. position. In this construction, there is employed a truss which isA pivotally supported at the lower' front portion ofthe end-standards' of the frame; and the folded bed comprises a central bedsection which is pivotally mounted upon the -arms of said truss, and substantially U- shaped front and rear bed-sections pvotally connected with the intermediate bed-section.

The seat hasits front portion connected with thel frame by aV sort of double-hinge arrangement, which permits the seat to be swung to a position in front of the frame, and the front bed-section is attached to the 4seat so that the bed will be unfolded when the seatisV swung to the inverted position. The rea-r portion ofthe rear bed-section is mounted upon links, or folding legs, whose lower ends are connected with guides which permit thefolding to take place.

ln the. accompanying drawings-Figure 1 tfeprcsents a sectional view of my improved combined sofa and bed in the open position; Fig. 2, a 'broken perspectiveview lllustrat- I ing the manner in which the truss employed is plvotally connected -with the' main frame; Fig. 3, a broken sectional view similar to the section shown in Fig. 1, but showing the structure in sofa form; and Fig-4, a broken horizontal sectional view showing the strucf. .ture in bed form.

In the preferred construction, A represents a main frame; B, a pivotally supported back C, a seat mounted on the main fra-me and. adapted to swing to a position in front of the main frame; D, a foldable mattress-frame, o1 bed-frame, normally housed within the main frame in folded condition beneath the seat .of the sofa, as shown in Fig. 3, E, a truss pivotally mounted on the main frame, upon which the folding bed is mounted and F, links, or folding legs, connected with the rearportion of the rear bed# section.

The frame A may be of any suitable construction. In the construction illustrated, it comprises end-standards 1' which may be of Wood and asornamental as desired; and a. rear connecting member 2 'joining said end-standards.

The back B may be of any approved .construetion. As shown, it is equipped at the upper portion of its ends with pivotal studs 2l which are received in pivot-sockets (not shown) with which the upper rear portions of the arms, or end-standards, l of the sofa are provided. The back stands normally in the rearwardl -inclining posit-ion shown in Fig..3, but w en disengaged from the seat of the sofa, the back drops automatically to the vertically depending position shown in Fig'. 1, so as not to interfere with the use of the bed. I

The seat C may be of any suitable con struction. It preferably comprises the-usual frame.. springs mounted thereon, and a cushion-'pad mounted on said springs. It has pivotally connected with its ends links 4, which, in turn, are joined byl-pivots 5 to links. The linkpf are pivotally connected with the 'frame in a manner"which will b'e presently described. The rem: portion of the seat is connected, by links. or chains, 7, wit-h the swinging edge of the. upper or front bed- .sectioIL The back B is equipped with astructure is in sofa form catch-member 8 which is rigidly secured thereto;'and a loop, or handle, 9 is provided, by means of which the back may be swung forward to enable it to be lockingly engaged with the rear portion of the seat. The rear portion of the seat is equipped with a movable catch 10 which is pivotally supported at l1, and which maybe released by means of a loop, or handle, 12. When the structlu'e is in the sofa. form, the catches are in engagement with each other, and release may be effected by n'ioving the catch l() through the/,medium of the loop 12. The particular form of means for locking the seat and back together is of 'no importance, and no claim to a specific device for sueh purpose is made herein.

The folding bed I) comprises an upper o1' front section 13; a lower or rear section 14; and an intermediate section 15. The inter- .mediate section is securely fastened by bolts 16 to the arms of the truss E. The intermediate section comprises end-members; and the front and rear sections comprise substantially U-shaped members having the eX tremities of their arms connected, respectively, by pivots 17 and 18, with the extremities of the end-1nembers of the intermediate section 15. AThe folding bed-frame, or mattress-frame, has attached thereto the flexible bed-bottom, or wire mattress, 19.

The truss E upon which the intermediate section 15 of the bed-fra1ne is mounted, comprises, in the form shown, a longitudinally disposed channel-bar 2O having pivot-studs 21 projecting from the ends thereof; and upwardly extending arms 22 which may be formed of angle-bars, secured. at rightangles to the channel-bar 20, the pivots 21 `projecting beyond the uprights 22. The arms 22 are connected with the longitudinal member 20 by braces 23. The ends of the arms 22 are provided with perforations 24 which receive the pivotal bolts 16 which serve to connect the intermediate bed-section with the truss. The end-standards -1 of -the main frame are equipped with pivot-plates 25 which are loca-ted at the front portions of said standards a short distance above the lower ends of the standards. 4The plates 25 are of Z-form, and -have perforations 26 adapted to receive the pivots 21 of the truss E, and perforations 27 adapted to receive pivotal rivets 28 which serve to connect the links (5 with the plates 25. The Webs 29 of the Z-form plates 25 are disposed horizon tally and aHord ledges upon which the links '6 bear When the bed is unfolded and the links 6 are in the horizontal position shown in Fig. 1. The channel-bar 20 of the truss E has secured to it a front piece, or molding, 30 which lies in a vertical plane when the and which swings to a horizontal ,plane when the structure is lin bed form. The space between the front portion of the seat and the front piece 30 is spanned by fabric 31 which conceals the interior structure. l

Pivotally connected with the end-members of t-he front bed-section 13 are folding legs 32 which have extensions above their pivots which are pivotally connected with links 33 whose opposite ends are connected, by pivots 34, with the intermediate bed-section.

The links F are joined by pivots 35 to the rear pori ions of the end-1ne1nbers of the bed* section I4, and the links have extensions 3G with which are pivotally connected links 37 whose other ends are connected, by pivots 38, with the intermediate bed-section. The lower ends of the links,. or legs, 'F are equipped with cam-studs 39 which move in inclined guides 40 with which the end-standards of the main frame are equipped on their inner surfaces. Springs 41 connect the legs F with the rear portion of the frame-section 14.

rI`he operation will be readily understood from the foregoing detailed description. The bed is usually made up before converting the structure t-o sofa form, the beddinff, which includes the mattress proper, the bedlinen and covers, being secured to the mattress-frame, or bed-frame, so as to fold therewith.' In converting to sofa form, the seat is swung from the position shown in Fig. 1 to the position shown in Fig. 3. In this operation, the links 4 and 6 assume the position shown in Fig. 3, and the bed-frame is folded to the position shown in Fig. 3. In the same operation, the truss E turns upon the trunnions, or pivots, 21, thus carrying the pivots 1G downwardly and rear'- wardly. At the same time the links, or legs, F swing rearwardly about the studs 39, while the studs 39 also slide in the guides 40. In the sofa form, the intermediate bed-seo tion 15 assumes a vertical position and the arms 22 of the truss E assume a horizontal position. After the seat has been swung to the normal position for use as a seat, the lower portion of the back is swung forwardly through the medium of the loop 9, and the back is loekingly engaged with the catch with which the seat is equipped.

In converting from sofa form to bed form, the loop 12 is employed to lift the rear'portion of the seat, the initial lift serving to release the back, which swings to the vertical position shown in Fig'l. -In the operation of swinging the seat to the position shown in Fig. 1, the links 4 and 6 Iare brought into substantial alinement, .and the links G rest upon `the ledges 29 ofthe pivot members i' 25. The links 4 are equipped with stops 42 which engage the projecting ends of the linksl 6, so that the edge of the seat which lies adjacent to the frame in the inverted position of the seat will be supported` through the medium of the links 4 vand 6. The opposite edge ofv the seat is supported .ist

. legs through the medium of the chains-7. In the f loperation of swinging the seat to the inverted position, the bed is unfolded through they medium of the chains 7, the truss E swinging upon its pivots so that its arms assume an .upright position and elevate the intermediate section of the bed. In the unfolding operation, the front legs 32 and rear F are swung to thev upright position through the medium of, the links 33 and 37, respectively. f

The foregoing detailed description has been given for clearness of understanding only, and no undue limitation should be understood therefrom. Hence,- the appended claims should be construed as broadly as permissible in view of the prior art.
