' 4 Claims. (01. 155-45) The present invention relates to improvements in folding furniture, and has for its object to provide a simple, strong and inexpensive article, whichmay be folded into a small compass when not in use, and which is adapted to have its parts ,so related as to form either a chair or a cot or couch. f V

.Articles of furniture of this class are commonly employed as porchfurniture, andthe object of the presentinvention is to providesuch an article which will comprise a minimum number of parts securelyunited, and which can be converted to either of the uses referred to with a minimum amount of effort. a

In the accompanying drawing:

Figure 1 is a side elevation of an article of furniture embodying the invention, showing the parts thereof positioned to serve as a chair.

Figure 2 is a front elevation of parts shown in Figure 1.

Figure 3 is a longitudinal section showing the arrangement of parts when arranged to constitute a couch or, cot. I 1

Referring to the drawing, in the several views .of which like parts are designated by the same reference character,'it will be seen that the improvements comprise essentially two main frames, one including parallel side bars 1 connected by suitable transverse bars 3, 3a, and the other comprising elongated parallelside bars 2, which are connected by suitable transverse bars or members 4,5,and6.

As shown in Figures 1 and-2,whenthe parts are related toadapt the article for use as a chair, said mainframes are positioned so that the side bars 1, 2, thereof are in intersecting relation and a strip of fabric, such as suitable canvas 7, is connected with'the cross bars 3, 4, andconstitutes the back andseat of [the chair.

Two arms 10 pivotally connected with the side bars 2 of one of the main frames are adapted to be detachably connected with the side bars 1 of the other main frame, and constitute arms of the chair andhold the same in the relative'positions shown. p

By disconnecting the arms 10 from the side bars 101 the main frame, said arms may be turned about their pivotal connection with the side bars 2 into a vertical position,such as shown in Figure 3, in which they constitute legs for supporting one end of the frames when positioned to constitute a couch or cot.

Wh'en'in this position, the bevelled upper end of the leg 10 contacts with the cross bar 5 to prevent turning movement thereof about its pivot in one direction, and each leg is disposed in subs'tantially the same vertical plane as one of a pair of links 13, which links are pivotally connected to the side bars of the main frames at points below the intersections thereof when related to serve as the frame of a chair. By this arrangement I insure that there is no danger of the stability of the cot being destroyed by unintentional turning of the arms or legs 10 about their pivotal connection with the members 2 of the main frame. A metallic plate 13a, disposed on the outer face of member 13, overlies the outer surface of leg 10 (Figs. 1 and 3) and prevents the respective legs from spreading. The end of bar 1 overlies a portion of the inner surface of leg 10 and prevents accidental collapse in the opposite direction. As stated above, the bevelled upper end of each leg 10 contacts the cross bar 5 and prevents pivotal movement of the leg outwardly away from the link 13. Because of the fact that leg 10 and link 13 lie in substantially the same vertical plane, pivotal movement of the leg in a clockwise direction (Fig. 3) is prevented by the end of the link 13 which acts as an abutment to arrest movement in that direction. Thus the legs are braced in four directions. I r r I Coil springs 15 depending from eyes attached to the cross bar 5 are adapted to be detachably engaged with eyes 16 on the side members 1 of the main frame and act to yieldingly support the fabric strip 7, so that it is adapted to serve as a comfortable bottom for the couch or cot when the parts are'positioned asshown in Figure 3. If no supporting means were provided between the ends of the .side bars 1 and the cross bar 5 of the second frame, thebars 1 would be forced downwardly by weight on the canvas 7 until they contacted the cross bar 6 located therebelow. By interposing springs 15 between the first-named frame and an upper portion of the second named frame, the fabric 7 is yieldingly supported at its lower ends because the cross bar 3 is permitted to give some under the weight of the person reclining upon thecouch.

When the parts are arranged to constitute a chair, as shown in Figures 1. and 2, thesprings 15 may alsobe engaged with theeyes 16 to assist in holding the parts in operative position, although, they are not necessary, and, if desired, may be arranged as shownin dotted lines in Figure 2, in which the ends thereof, adapted to engage the eyes 16, are interengaged one with the other.

An additional frame comprising side bars 20 pivotally connected with the sides 1 of the main frame and adapted to be turned to constitute an extension ofsuch frame, as shown in Figure3, or to lie behind, and depend from, said main frame when the parts are positioned to serve as a chair, completes the article, 5 1 V The side bars 20 of the supplemental frame are cohnected'by cross bars 21, which are united by-a strip of canvas, or suitable material 22, and when such supplemental frame-is positioned as shown frame, said material 22 serves as a portion of the top of the cot or couch.

Each of the side bars of the supplemental frame is provided with afoot 23, which, when the parts are positioned as shown in Figure 3,

serves as a support for the lower end of the cot;

or couch. Each foot is pivoted tothe adjacent side bar 20, and may be swung inside of the same when not in use, as shown in Figure 1. Cross bar 21a acts as a stop and holds the legs upright when they are in supporting position. 1

When the parts are positioned to constitute a chair, as shown in Figures 1 and 2, the supplemental frame is retained in'the operative position shown by means of a hook carried by one of the side bars 1 of the mainframe and engaging an eye on a side bar of the supplemental frame. In this position the supplemental frame is in rear of and entirely concealed from view by the seat and back portion 7 of the chair, and yet does not in any way interfere with the use of the chair.

By disconnecting the arms 10 from the projections 12 and allowing the same to assume a vertical position and turning the supplemental frame section about its pivotal connection with the main frame, the parts can be readily converted into the relation shown in Figure 3 and adapted to serve as a comfortable couch or cot.

When desired, by disconnecting the arms 10 from the side bars 1 of the main frame, the main frames can be folded into substantial alignment with each other and with the supplemental frame, so that the entire article will occupy a minimum amount of space.

It is believed that the manner of use and advantages of the improved article will be readily apparent from the'foregoing description in connection with the drawing, and it will be understood that except where specifically described in the appended claims, the invention is not to be limited to the exact details shown, the drawing being intended to be illustrative rather than restrictive of the invention.

When the parts are positioned to serve as a chair, the latter is capable, owing to the pivotal ing, in combination, two main frames each including two parallel side bars, the side bars of said frames being in intersecting relation, cross bars connecting the side bars of each frame, a strip of fabric uniting said cross bars, arms pivotally "connected to the side bars of one of said frames and having means. for detachably connecting their other ends with the side bars of the other said frame; whereby when said arms are detached from the'rlast said frame they may assume a vertical position and constitute legs of a cot, two links pivotally connected respectively to the respective side bars of both frames at points below the'intersection of said bars, a supplemental section including parallel side bars pivotally connected to the side bars of one of the main frames,

whereby they may be positioned to form a con-' tinuation of said main frame or to lie behind said main frame, cross bars connecting the side bars of the supplemental section, a strip of fabric united to the cross bars of the supplemental section, and a foot piece projecting downward'from said supplemental section when it is positioned to form an extension of the main frame.

3. A combined folding chair and cot, comprising, in combination, two main frames each including two parallel side bars, the side bars of said frames being in intersecting relation, cross bars connecting the'side bars of each frame, a strip of fabric uniting said cross bars, arms pivotally connected to the side bars of one of said frames and having means for detachably connecting their other ends with the side bars of the other said frame, whereby when said arms are detached from the last said frame they may assumea vertical position and constitute legs of a cot, two links pivotally connected respectively to the respective side bars of both frames at points below the intersection of said bars, a supplemental section including parallel side bars pivotally connected to the side bars of one of the main frames, whereby they may be positioned to form a continuation of said mainframe or to lie behind saidmain frame, and means for fixedly securing the supplemental section in predetermined rela-' connections between the main frames by the bars. tion t the adjacent m fr m when the frames 13 to have a limited rocking movement, and when the parts are adjusted into the relation shown in Figure 3, the resulting cot or couch has a yielding or flexible bottom extending substantially throughout its length.
