SOFA-BED.

Application filed November 5, 1912. Serial No. 729,665.

Beds, of which the following is a specification. y

This invention relates to sofa beds, and more particularly to that type of sofa bed comprising seat and back members which are hinged together and provided with looking and unlocking means, so that these members may be swung in fixed angular relation and then spread out flat to form a bed, the members being connected with a supporting structure and guided and controlled in their movement by two pairs of pivoted levers or links, known in the art as standards and throw-bars. m The object of this invention is to produce a bed of this character of simplified and inexpensive construction, and especially to provide an all-metal sanltary bed without projecting end pieces, suitable forhospital or other use, and capable of being readily taken apart for cleaning and for shlpment in compact condition. 0

The preferred embodiment of the mvention accordingly comprises seat and back members of metal construction, hinged and connected as aforesaid, an underlying metal supporting frame on which the bed sectlons rest, and pivoted standards andthrow bars which are separably connected wlth such underlying support.

In the accompanying drawings illustrating the invention; Figure 1 is a perspect ve view of a supporting frame with the two bed sections omitted; Flg. 2 is a vertical sectlon through the bed, part being broken away, in sofa or davenport condition; and Fig. 3 is a similar view showing the two members spread out to form a bed.

The seat and back members 10 and 11 are of metal frame construction, as shown more particularly in my copending application Serial No. 729,664, filed November 5, 1912. Each member preferably comprises a bottom frame 12 of angle iron, angle iron corner pieces 13, and spring-fabric supporting end angle bars 14 carried by these corner pleces at a sufficient distance above the bottom frame to prevent the spring-fabric sagging into contact With'parts beneath. The spring structure or mattress is not shown, but may be of any suitable character. The members are hlnged together, as by extended ends of the bars 14-. with their flanges cut away and connected by a pivot 15. A tie rod or locking link 16 with a releasing dog 17 carried by the seat member and cooperating with a pin 18 on the backmember constitute means for locking and unlocking the members. The operation of this construction is well knownin the art. Suffice it to say that when the seat member 10 is lifted at its forward edge and swung upward the tie rod 16 holds the member in fixed angular relation, so that the back member 11 is lowered to horizontal position. Further movement causes the releasing dog 17 to drop by gravity into engagement with the pin 18, so-that reverse movement of the seat causes said dog to lift the tie rod 16 out of engagement, thereby permitting the seat to be lowered alongside the back. To restore the parts to sofa condition the seat is raised only until the tie rod 16 drops into engagement with the pin, after which downward pressure on the seat swings the back up into vertical position. v

The underlying supporting frame is indicated as a whole by the reference character 20. In the construction illustrated it comprises front and back supporting angle bars 21, 22, having legs 23, 24 to rest on the floor, these legs being formed by bending the end portions of said bars downward vertically, the vertical flanges of the bars being mitered at the bend and the legs being braced by diagonal struts 25. The bars 21, 22 are connected at the tops by cross bars 26 in the form of T-irons having the end portions of their vertical depending flanges cut away with the shoulders so formed abutting against the inner edges of the horizontal flanges of the front and rear bars 21, 22. Side bars 27 connect the legs 23, 24:- These bars and the cross bars 26 are bolted or screwed in position, so that the supporting frame may be taken apart and tied up in a compact bundle.

Rearwardly inclined standards 28 are pivoted at their lower ends to the sidebars 27 and at their upper ends on the hinge pin 15. Forwardly inclined throw bars 29 are pivoted at their lower ends to the back legs 24; and at their upper ends to the back member 11. The connections of the standards and throw bars with the underlying support are separable. To this end the side bars 27 Specification of Letters Patent. Patented Man 17, 1914 have key-hole slots 30 to receive headed studs 31 carried by the standards, while the throw bars are pivoted on stud bolts 32 and are held thereon by nuts 33. Thus the bed members may be readily separated from the su port and folded together for compact shipment or storage. In effect the bed comprises but two parts, one being the hinged bed members and the other the underlying sup orting frame, and these two parts are rea ily separable yet solidly and firmly connected. As shown in Fig. 3 the bed members rest directly on-the supporting members 21, 23 and 22, 24.

What I claim as new is:

In a sofa bed, a metal supporting frame comprising front and, back members each of which consists of a single angle bar bent and braced at the ends and extended vertically downward to form legs to stand on the floor, and bars extending from front to back and detachably connecting said front and back members, in combination with hinged seat and back bed sections of metal framework adapted to be spread out on said supporting frame to form a bed, said frame being entirely beneath the bed sections and said bed sections being adapted to rest on said front and back members having the down-bent legs, and standards and throwbars pivotally connected with said sections and pivotally and detachably connected with said supporting frame.

In witness whereof I have signed my name in the presence of two subscribing i;
