A CORPORATION OF MICHIGAN FOLDING BED' Application led September 25, 1828. Serial No. 308,226.

rlhis invention relates to folding beds. It is an object and purpose of the present invention to provide a folding bed structure which in one position is extended into the form of a double bed and in its folded position is a couch or davenport. The invention consists in many novel details of construction and of arrangements and organizations of parts for provi-ding a folding bed structure of the type and easily changed from one position to the other, is of economical manufacturing construction and is effective to fuliill the purposes for which it is designed.

An understanding of the invention and the construction embodying the same may be had from the following description taken in connection with the accompanying drawings, in which,

Fig. 1 is a transverse vertical section through the folding bed in its folded position, the section being taken immediately inside one end of the bed.

Fig. 2 is a similar section showing the bed in the process of being turned to its unfolded position.

Fig. 3 is a like section with the bed in its completely unfolded position, and

Fig. 4 is a fragmentary, longitudinal, vertical section through one end of the bed when it is folded, as in Fig. 1.

Like reference f characters refer to like parts in the different figures of the drawings.

In the construction of the bed two spaced apart ends are used including in each a front I respectively, while a Vback 5, suitably upholstered, extends between the rear posts 2 at the upper portions thereof. Each end is completed as indicated at 6 by end frames which make the ends of the couch or davenport when the bed is in folded position.

At each end of the construction, substantially between the horizontal rails 4, and de tachably connected to the posts 1 and 2 are supporting frames, each formed of two vertiars 7 and two parallel horizontal bars 8 permanently secured at their ends to the upper and lower ends of the angle bars 7. These frames are detachably secured to the posts 1 and 2, the outwardly extending legs of the angle bars 7 being diagonally slotted upwardly and inwardly to connect with headed pins 9 (see Fig. 4) fastened to the inner sides of said posts 1 and 2. Substantially midway between the ends of the bars 8 a vertical bar 10 is located and connected at its ends to said bars 8, while back of the same and at the opposite side of the bars 8 a vertical post 11 is secured which extends above the frame and at its upper end is formed with an outturned lip 12, the purpose of which will later appear.

Two links 13 and 14 are pivotally connected at one end to each of the front posts 1 and the bars 10 as best shown in Figs. 2 and 3, and each of said links at its opposite end is turned at an obtuse angle making the extensions 15 and 16. Said links are pivotally connected to the ends of a horizontal frame 17 which lies between the end boards 3 and which is movable to different positions on pivotal movements of the links 13 and 14.

At the front side of the frame 17 and at each y one of which a mattress 2O is placed, whilecoiled springs 21 extend between and are secured at their ends to said frames 19. The mattress 2O is substantially twice the width of the frame 17 or the spring structure supported thereby, one-half of the mattress only being supported above the spring structure while the other half is otherwise supported as will be later described. The links 13 and 14- at each end of the bed are connected by a horizontal bar 22 at a point beyond the pivotal connections of said links to the ends of said frame. i

A second spring and mattress supporting frame 23 adjacent one side and at each end,

carries posts24 which in the unfolded position of the bed, shown in Fig. 3, are located in front of the posts 18 and extend upwardly from the frame 23 and at their upper ends are curved tothe rear, being pivotally connected to the upper ends of the posts 18. This permitsv the frame 23 to be turned through 180 from a position where it lies overl the frame 17, as in Fig. 1, to another position where it lies in the same horizontal plane with the frame 17, as shown in Fig. 3.

The frame 23 is made of angle bars and carries an open wood frame 25 (see Fig. 4) with which a spring and mattress and cushion structure is connected. r1`he cushion coverY 26 is fastened to the frame 25, extends therefrom and covers cushioning material 27 which is located over a plurality of coiled springs28 extending from the cushion 27 through the frames 25 and 23 and connected aty their other ends to a wire frame 29 to which the other half 30 of the mattress 2O is secured. The frame 25 with the cover 26, cushion 27 and spring structure 28 and 29 are readily assembled as a unit and then joined with the supported frame 23.

When the frame 23 is turned to its unfolded position, as shown in Fig. 3, the mattress sections'20 and 30 lie respectively over the various spring structures carried by the frames 17 and 23 and the unfolded mattress is in. a horizontal plane. On turning the frame 23 about the pivots connecting posts 18 and 24 to the position shown in Fig. 1 the mattress sections 2O and 30 are folded upon each other and the cushion 27 is disposed. between the endsof the davenport bed and is at the upper side whereby a spring supported cushion for a davenport or couch is rovided.

The bars 22 connecting links 13 and 14 are joined with the posts 24 by means of links 31,7best shown in Fig. 3, which are pivotally connected at their ends to said bars and posts. An irregularly shaped bar 32 at one end has an arm 33 pivotally connected to each link 31 and at the opposite end has an arm 34 extending substantially in the same direction as the arm 33 which is pivotally connected toa supported leg 35 at one end thereof. Said leg, a short distance from where it is pivotally connected to the arm 34,

Vis pivotally connected between its ends to the end of the frame 33. When the bed is in unfolded position, as shown in Fig. 3, the irregularly shapedbar 32 at each end is in substantially inverted U-shaped position and the legs 35 extend downwardly from the frame 23 and rest upon the floor thereby supporting the outer part of the frame 23 in the same horizontal plane with the frame 17.

The extensions 16 are bent at an angle from the links 14, one at each end 'of the bed, extend a distance beyond where they are pivotally Y:connected to the bars 22'. A coiled tension spring 36 is secured at one end to the free end of each extension 16 and at its opposite end to a link bar 37 which in turn is connected with the U-shaped bar 32.

When the bed is in its unfolded position, as shown in Fig. 3, the links 13 and 14 have been swung forwardly in a clockwise direction from a position below the horizontal to vertical position. The bars 22 lie directly over the ends of the frame 17 which furnish stops against which said vframe'V engages. The frame 17, with its superimposed spring and mattress structure, has been lifted from a lower position toY an upper and somewhat forward position. rThe other s-pring and mattress supported frame 23 lies in the horlzontal plane with the frame 17 and is held in such position, being supported at one side bythe depending posts 24 and at the outer side Vby the ysupporting legs- 35.

On folding the bed the entire outer frame structure 23 with the attached bars 32 and legs 35 are turned about the pivots connecting the posts 18 and 24. Themovement of the posts 24 through the connecting links 31 causes a longitudinal and downward movement of the bars 22 which actuates the links 13 and 14 to move pivotally in a reverse or counterclockwise direction, thereby lowering the entire structure to the position shown in Fig. 1. Springs 36, under tension aid 1n the folding operation as the same partially counterbalance the weight of the frame' 23 and the constructions attached thereto. Inthe fully foldedposition the frame 23 rests at the rear on the lips 12 at the upper ends of posts-11 andv at the front are supported by the posts 18 and 24 as shown iii/Fig.l 1. The U-shaped bars 32 are also automatically moved so as to swing into horizontal position alongside the ends of the frame 33.

This construction has proved very practical and effective in service.V It4 1s readily and easily manufactured and assembled. The invention is defined in the appended claims and is to be considered comprehensive of all 'forms of structure coming within the scope of said claims.
