GOPERT COMBINATION SEAT AND FOLDING BED 2 Sheets-Sheet 2 Filed July 19, 1950 United States Patent COMBINATION SEAT AND FOLDING BED Gote Yngve Mattias Gopert, Joukopiug, Sweden Application July 19, 1950, Serial No. 174,713 1 Claim. or. -36) This invention relates to convertible furniture, such as a sofa or a chair, which may be unfolded to form one or more beds.

An object of the invention is to provide a folding bed requiring only a few number of parts which are of a simple and rigid construction.

Another object is to provide a folding bed which can be easily operated and in which the bedding may be folded together with the bed frame.

A further object of this invention is to provide a simple connection between the bed frame and a main frame as well as between different sections of the bed frame whereby these sections may be manufactured and provided with fixed seat or back cushions independently of the manufacture of the main frame and thereafter be easily mounted together. A still further object is to provide a simple construction of a support for the unfolded bed frame to be used for special purposes when the bed has been folded.

Other objects and advantages of the invention will be fully understood from the detailed description hereinafter, reference being made to the accompanying drawing, in which:

Fig. 1 is a vertical section of a folding bed according to one form of the invention.

Fig. 2 is a vertical section of the folding bed in bedforming position, and

Fig. 3 is a corresponding plan view thereof.

The folding bed is shown in the drawing as a chair having two end portions 1 connected with a back portion 2 to a main frame enclosing a space for a bed frame. This frame is formed of four sections 3, 4, 5 and 6 being hingedly connected to each other, and the front section 4 is pivotally supported by pins 7 secured to the end portions 1. The bed frame sections are made from steel tubes having a longitudinal flange 8 provided with holes for fastening a resilient bed bottom. The longitudinal frame members of the section 3 have their inner ends connected by a cross member 9 which slides on two sloping guide surfaces 10. The front section 4 is at its lower end provided with a U-shaped cross frame member 11, and the back section 6 has at the top end a cross frame member 12 in the same plane as the longitudinal frame members. These cross frame members form a rigid cross connection between the longitudinal frame members, and it should be noted that they do not form any obstacle for the resilient bed bottom owing to their construction or location.

On the longitudinal frame members of the seat section 5 is fastened a closed seat frame 13 of angle iron or of tubes. Its rear end is bent upwardly to a position parallel to the back section 6 against which it rests, and its fore end, which projects over the fore joint of the seat section frame, is bent somewhat upwardly to form a rigid support of the fore end of a seat cushion 18. The longitudinal frame portions of the closed seat frame are connected by four cross frame portions of which 14 and 15 are located at the ends, 16 at some distance above the 2,718,643 Patented Sept. 27, 1955 lower ends of the rear portion which is bent upwardly and 17, which is U-shaped at some distance infront of said ends. It is obvious that also these cross frame portions allow the bed bottom to be depressed sufliciently. The cross frame portion 17 serves to maintain the longitudinal frame members of the seat frame 13 and thereby also both frame members of section 5 in fixed relation to each other, and as the member 17 is located at the rear end of the seat cushion and connected therewith it is of no inconvenience when the chair is used in folded position. To the closed frame 13 a number of lugs 19 are welded which are removably connected with the frame 5 by bolts 19', and to the cross bar 15 a U-shaped bolt 21 is welded to serve as a foot when the bed is unfolded. The seat cushion 18 as well as the back cushion 29 are secured to the frame 13 in any suitable way.

The back section 6 is at its upper end at 22 hingedly connected to a metal how 23 having its shanks located at the outside of the longitudinal frame members of the back section, and to this bow an angle-shaped frame 24 is welded and adapted to rest with its upper cross portion on the top of the back 2 thereby causing its lower cross portion to rest against the bow 21. This frame which can be made from an angle iron or a tube is provided with an upper back cushion 25 secured thereto.

When the bed frame is unfolded the cross member 9 slides on the guide surfaces 10 to an end position on a shoulder 26, and the frame section 3 may in its upper position be further supported by any suitable means. When the seat section is swung 180 the bow 21 will rest on the floor, and the rear, upwardly bent portion of the frame 13 thus serves as legs for the seat section 5. The frame 24 is automatically swung out from the back section 6 to serve as end legs for this section.

I t appears from the above that all cross frame members are located at a sufficient distance from the resilient bed bottom, and that they are of no inconvenience or serve special purposes in the folded bed. When changing the article of furniture from one position to the other this may be performed by a single and simple operation without removing any cushions or other parts in advance, and the bedding accompanies the bed frame whereby the bed is at once ready for use. Another advantage is that the frames 13 and 24 may be manufactured and provided with the cushions independently of the manufacture of the main frame, to which they may easily be mounted afterwards. The seat section requires no support from below when used as a seat as it rests against the back section 6 by the upwardly bent portion and sections 5 and 6 form a system supported only in two fixed points. In the drawing the main frame is shown to be made of wood, but it is also possible to make them of another material and also as a tube frame.

I claim:

In a combined seat and folding bed, a main frame having two end members and a back member connected there to, a bed frame having a plurality of sections hingedly connected one to another, one of said sections being pivotally supported by said main frame, one of said sections comprising two longitudinal frame members forming both a seat section and a bed section, and one of said hingedly connected sections forming a back section, a closed metal seat frame secured to said longitudinal frame members and provided with supporting means for a seat cushion, said closed metal seat frame comprising two longitudinal frame portions and two end cross frame portions, the rear end of said closed metal seat frame being bent upwardly so as to form a bow member which is upholstered and serves as a support for the seat section of the unfolded bed, and the fore end of said closed metal seat frame being bent slightly upwardly to serve as a support for the fore end of a seat upholstery, and an angle-shaped, up-

ice

holstered back frame pivoted 'to the top of said back sec- 7 tion and comprising a downwardly extending portion bearing in its folded position against said bow member and serving in the unfolded position of the bed frame as a'support for the back section and a rearwardly projecting portion resting from above on the top of the said back member and bearing against the fore side thereof for carrying the back section and the seat section in their unfolded position.
