7 Claims.

My invention is an improvement in sofas or settees of that special type which is convertible to a bed by extending a slidable section beyond one end thereof to increase the length of the sofa, the width of the extended article of furniture corresponding with that of a single bed.

In the present instance my invention contemplates the provision of a small sofaorsettee,commonly known as a love-seat, in which a slidable section forming a part of the bed frame is normally housed within the main supporting frame and forms a part of the seat bottom thereof, to support a sectional pad or folded mattress providing the upholstered part of the seat when the article of furniture is being used as a sofa and to also provide the mattress when the structure is extended to bed form.

A further object of my invention is to provide a convertible sofa and bed in which the slidable section: forming a part of the bed frame, is connected to the seat structure in such a manner that said slidable section can be extended its full length beyond one end of the seat frame, whereby a comparatively short sofa or love-seat is provided convertible to a bed of a standard length.

My invention further contemplates an economical arrangement for a convertible sofa and bed which includes a dual seat-bottom frame or a folding bed bottom frame constructed of angle irons, with the two parts thereof hinged together and employed in connecion with the seat supporting frame and associated slidable bed frame section, the dual seat and bed bottom frame when a folded forming a reinforced seat bottom for the article of furniture in its use as a sofa or loveseat and a bed bottom when the structure is converted to bed form.

With these principal objects in view my invention consists in the construction of the dual element forming the seat and bed bottoms, and in the combination therewith of a slidable bed frame the feet 15 at the other end of the sofa.

frame broken away to show the hinge and slidable connections between the movable parts.

Fig. 4 is a plan view of the article of furniture in bed form'without the mattress. v

Fig. 5 is an enlarged detail sectional view show-e .5 ing the means for connecting the movable parts, including the slidable section of the bed frame and swinging section of the bed bottom.

Fig. 6 is a sectional view on the line 6-6 of Fig. 5. i

Fig. '7 is a perspective view of a corner of the main frame, the slidable and swinging sections being removed, and

Fig. 8 is a detail perspective view of the slid connecting the slidable section of the bed frame: 1 to the stationary part of the seat and bed bottom.

In carrying out my invention I employ any conventional construction or type of main frame which will present a sofa or love seat of attractiveappearance, it being essential however that one end thereof be detachable and movable with the extension section to form one of the end pieces of the bed as well as an end piece of the sofa. As illustrated in the drawings the main frame is; in the form of a box-like seat framewith front and rear sides II], II, permanently connectedat one end by a crosspiece I2 with corner posts l3, l3, and at the other end by a narrow bottom board I 4, the corner posts being extended to'form feet l5 at one end of the frame while the other end is supported by feet l6, IS. The structure is completed as a sofa. frame by a movable end piece comprising corner'posts I1, I! connected by a crosspiece l8, and this movable end piece 4 is a part of the extensible bed frame section, hereinafter described, with the lower ends of the corner posts shaped to form feet I9 cooperating with the feet l6 of the main frame so as to match Within the main frame there is secured a rectangular frame 28, forming one part of the combined seat and bed bottom, said frame being, preferably constructed of angle bars with side rails 20a, 20a and a cross rail 20b at one end, while the other ends of said side rails are connected by hinges 2|, 2| to the contiguous ends of a similar seat and bed bottom frame 22, consisting of opposite side rails 22a, 22a and cross rail 22!). The frame 20 upon which the frame 22 is folded is permanently attached at one end to the crosspiece [2 of the main frame by screws 23 (Fig. 6) and at its other end is supported on and attached to angle brackets 24, 24 mounted on the crosspiece I4, it being noted by reference to Fig. 7 that the ends bf the side rails or angle bars of this frame are securely attached to the 7 angle brackets by rivets 25, 25, so that the depending member of each side bar or rail will be spacedfrom the angle bracket and a short distance from the adjoining side of the sofa frame for the operation of the slidable element (hereinafter described), connecting the extensible ,sec-

. '7 tion of the bed frame to the stationary "section.

This arrangement provides the supporting means for'a dual seat and'bed'b'ottom frame'adapted to be unfolded for the'purpose of forming the bed bottom, and as it isintended to use any conventional construction'or type ofwire-fabric 'gfor the seat and bed bottom, with the usual helical springs (not shown), there is considerable tension on the bed frame laterally and consequently i bed frame by'riVetsZSw'. V

I provide a tubular brace 26 extending between to brackets '28, 28 fastened to the corner posts 11,1! of the movable end piece'of'the; sofa and at their inner ends by slides 29, to the angle bars ZUa, 20a; of the stationary section of the dual seat and bed bottom, the aforementioned slides and side rails of the extensible section of a V the bed frame being disposed at the outer sides 35: V V

of ,the dual seat andbed bottom frames 'to travel in-the spacebetweenthe side rails of thesta tionary section or said frames and side pieces of h fa-,,@ I

gThe slides'are of a particular construction to travel oonthe'a'n'gle bars 20a, ifor which purpose each slide is provided with astraight'flange 29a at its upper edge, overlying the upper'member of said angle bar, andwith'an outwardly and upwardly turned flange 29b'at its lower edge to receivethe dependingmember of said angle bar thereby insuring positive sliding engagement.

7 The side rails 21 of the extensible section of the bed frameare connected to the outer'ends of Y 7 these. slides by pins 30, and in order to provide ',for the desired extraordinary extension of this section the pin" connecting each slide engages a hole 290 in the slide and a horizontal slot 3| in ,the side rail 21; that is to say, by this arrangement the side rails of the bed frame section may be of substantially the same length as the side pieces of the seat'frame, and in the closing oper-- ation of this bed frame section the inner ends of the side rails thereof move on the slides or con- -necting pins 38 the full length of theslots so as to. extend approximately to the crosspiece l2 of the mainframe (see dotted lines, Fig. 4); Conversely when this bed frame sectionis extended to its fullest extent it is entirely beyond the end of the seat frame .(see Fig.4) with its inner end firmly supported by the projecting ends of the slides, thus providing a bed frame of a standard length and a comparatively short sofa or loveseat. When the slidable bed framesection is ex- 7 b tended it receives the folding section of the hinged bed bottom, and for supporting the outer or free :end'of this folding section on the bed frame within the slidable section thereof it is provided with projecting pins 32 seating in corresponding recesses '33 in the side rails 21.

The particular construction of the extensible bed frame section and its slidable connection with the stationary seat bottom frame, including the folding part of the bed bottom, provides metal parts for a convertible sofa and bed of simple'and economical construction, durable in use, and

which may be easily manipulated in converting the sofa or love-seat to bed form, and vice Versa.

As will be seen the parts are locked in extended position or bed form by the engagement of the pins 32 in the recesses 33, and in order to lock the extensible bed frameisection in place when the article of furniture is being used. as'a sofa or love-seat-any suitable form of catch device may be employed, one member, as 34, of which is secured to the posts ll of the movable end piece and the other member, 35, attached to the underside of the bottom board M of the seat As no claim is made to this catch or locking device, per se, it is not shown tintdetail, it being understoodhjowever that one ofthe memframe.

bers, .34 or 35, may be in the form of spring jaws engaging the other member, or one of the conventional forms of friction catches for holding the slidable section closed and force to open and close it.

v 7 From the foregoing de scription in connection with the drawings "it will be readily seen that the construction provides acomparativelyshort sofa. l inthe form of a love-seat, as illustrated in Fig.

l, adapted for day use, andthat byextending the bed/frame section it will serve to support the folding-section of the bed bottom so that the pad orupholstered' portion ofthe seat, which is removedxin the operation of converting the article of furniture from a seat to a bed, is unfolded trated in 'Fig. 2. When the article of furniture requiring a little j an'd serves as the mattress for; the bed, illusis 'used as a sofa or love-seat it is placed near 'a'wall, and as the seat is a little wider than usual for a sofa, pillows may be used to form a back 7 for the sofa or love-seat.
