JOHN A. ARTON, OF CHICAGO, ILLINOIS.

CONVERTIBLE FURNITURE.

Application filed July 26, 1920, Serial Nb. 399,025. Renewed November 11, 1926 practically continuous movements of the.

parts. a

By means of my invention hereinafter described, I am able to produce a simple and comparatively light device which is opened or extended by a practically continuous movement of the extending parts. The general features of my improved beds are set forth in my Patent No. 1,281,265, issued October 15, 1918. But by improvements thereon I am able to do away with a considerable number of parts, thereby lightening and sim lifying not only the bed portions but the amework with which they are contained. It is a further objection to many of the bed devices heretofore made, that it is necessary to completely disassemble the sofa in order that it may pass through doors of ordinary width. I am further able by means of my improvements to provide a substantial framework within which all of the moving parts of the bed mav be contained for shipment, the internal space being utilized and the external dimensions being reduced, thereby reatly reducing the space required for freigfilt shipments. In connection with my said improvements, I also provide a device by which the movable parts of the combination are held in rigid relative positions when used as a sofa.

The rinciples of my invention are illustrated in the drawings in which Fig. 1 is an end View of my device, the near end being removed. Fig. 2 is a similar view with movable parts partly extended and Fig. 3 shows the parts fully extended for use as a bed. Fig. 4 is a top view of a portion of Fig. 3. Fig. 5 is a detail of the removable head and locking device. Fig. 6 is a front view of the same. Fig. 7 is a locking device latch and Figs. 8 and 9 illustrate means by which said removable head may be attached to the body of a davenport.

Further describing my invention with reference to the drawings in which like characters of reference denote like parts throughout; 1 and 2 are respectively the rear and front legs of a sofa bed frame, while 4 repthe head section.

resents the arms and 5 the end panels thereof. An attaching structure 6, connects the rear posts of the bed. A seat having the end piece 10, the front or finishing piece 11, and the back piece 12provided on its normally upper side with upholstery 13 is swung at the ends and overturnable in trunnions 14 which are attached to the end pieces or panels of the frames.

A back having the foundation 16 and upholstery 16 is mounted on the extension framing of the bed by means hereafter to be described.

A folding bed structure is adapted to be connected to the under side of the seat and extended transversely therefrom in opposite directions. One section thereof having a plurality of end members 17, is attached to the under side of the seat, and the ends 17' are extended rearwardly therefrom as shown in Fig. 1. To the said extended ends are pivoted at 18 the members 19 which form the ends of the back section. Drop arms 20, are securely attached to the extended portions of the members 17. Drop arms24 are attached to the back section'members 19 at a short distance from the point of their pivotal attachment to the seat member 17. Bracket-s 25 are secured to the seat section end members 17 at points adj acentto their inner ends and have upwardly-projecting flanges 25 to which at 26 are pivoted end members 27 of members are attached to each other by the tion for the completed bed frame. The inner ends 29 of the head section are formed by cutting away the lateral flange of the angle iron of which the member is com osed, thereby leaving the vertical flange which will pass readily by the outer face of the seat member 17 when turned as hereinafter described. Pivots 30 attach the inner ends of said members 29 to one end of connecting bar 31. The other end thereof is pivoted at 32 to the drop arms 24 on the back section members 19 and the adjacent end thereof is extended beyond the point-of pivotal attachment to the said drop arm for a purpose hereinafter to be described.

The outer or foot end of the bed is formed similarly to the head section and consists of end members 33, connected by the. transverse angle bar 34, thereby forming a foot section. The inner ends of the end members have the lateral flanges cut away for some The outer ends of said distance, leaving the vertical flanges which form levers 36 which are pivoted at 37 to the bracket 38 at the extreme ends thereof. Said levers are pivoted at 39 to one end of connecting bars 40, the other ends of which are pivoted at 41 to the drop arm 20. The

back of the sofa .is mounted on the extension portions of the bed frame by means of a hinge having the leaf 42 and the leaf 43 turned into a-plane at right angles to the other leaf .at 44. The leaf 42 is securely attached to the foundation 16 of the back. The leaf 43 is pivotally attached at 44' to the end piece 19 of the back section. A tie bar 45 is pivoted to the leaf 43 at 46 and the other end of said tie bar is pivoted at 47 to the extension 31' of the connecting bar 31. By means of this connection and pivoting the back is caused, by means of thefolding and unfolding of the bed parts to assume the respective positions as shown in Figs. 1, 2, and 3, in the latter of which it assumes the position and performs the function of a leg to support the extended bed frame.

'- In order that the extension bed frame may be retarded or aided in its movements, I

provide a helical spring 63, which is attached at one end to the head section 27 and at the other end to the bed frame as at 63. This when provided of proper dimensions and strength acts as shown .in Fig. 1 to aid in opening the bed and as shown m Fig. 2 to retard opening motion at the latter portion thereof.

In'the ordinary and usual construction of davenports and similar articles of furniture which are to be used as the supporting and containing'parts of extension bed structures, it has been customa to extend the rear legs upwardly to a conslderable distance above the .arms thereby forming a head. This is done both for symmetry and to provide a space which corresponds to the upper portions ofthe folded bed irons and in connection with which, such movable partsmay be secured and concealed. The ends of such head, have heretofore been formed integrally with the legs as upper extensions thereof. But for the purpose of reducing external dimensions of the bed frame for packin and shipment and for the purpose of provi ing a rigid independent structure to whicha closin or concealing piece may be pivotally attac ed and for the further pur se of utilizing such concealing pieces as a. part of the lockin device, I construct the head? independent y of the frame. In so doing I only cause the rear legs to be extended upwardly as far. as the arms 4, to which they are framed. My improved head com rises the end pieces 70, a back piece 71 an a top or closing piece 72. The ends and back should be strongly and firmly framed together to make a permanent and independent structure to which the top or closing piece may be pivotally mounted within the ends thereof.

The pivoting device provides a foundation piece 73 rigidly secured to the end pieces by screws 74. mounting piece 75 of angle iron is pivoted to the upper end of 7 3 by its vertical flange, while the transverse flange is rigidly secured to the finishing piece or board 72 which can thus be turned on the pivot to close the space above and rearwardly of the back or to permit clearance when the bed members are opened out. Midway of the foundation piece 73, at 76 is pivoted a latch or hook 77 shown in enlarged form in Fig. 7. One end thereof is provided with a book 78 and the other end ispivoted at 79 to a link 80 which is attached at 81 to the mounting piece 7 5 on which the closing board 7 2 is mounted. 1

It will be seen that when the finishing piece or board is in the position shown in Fig. 1 or as shown in enlarged detail in Fig. 5, the latch 77 will engage the leaf 43 by which the back is hinged to the end piece .19 of the back section. When it is desired to extend the movable portions to form a bed, the top or finishing board is raised, thereby depressing the link 80and raising the book 77, permitting the movable portions to be extended.

The entire structure last described issecured to the seat arm in such manner as to be readily removable. The arm-4, is provided with slots 85 and the end pieces 70 may have screw threadedly attached thereto the L books 86 which may be turned into looking or disengaging relation to the arm 4.

JOHN A. Aaron.
