CONVERTILE SOFA. CHAIR AND COUCH.

Specification of Letters Patent.

Application led June O 1910. Serial No. 567,762.

To all whom it may concern: y

Bc it known that we7 Jaco Kuoni-inni and' Zot/ran B. Csinr, subjects ot' Austria- Hungary, residing at Cleveland, in the countyot Cuyahoga and State of Chio, have invented certainnew and useful Improvements in Convertible Sofa Chairs and Couches, of which the following is a specification.

Our invention relates to a convertible sofa chair and couch. the same being adapted to be used as a chair with or without a reclin ing back and as a base rocker and also to be opened into a couch or bed, all as hereinlaiter fully described and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a vertical sectional elevation 'lront to reary of our invention with the parts in the po sition of'a chair but locked in respect to the base to prevent rocking. Fig. 2 is a cross section on a line corresponding substantially to @@ag Fig. 4,' looking to the right. Fig. 3 is a plan view of a portionA of the invention showing the parts open to tor-m a bed. Fig. 4 is a longitudinal sectional elevation of the structure partly broken out at one end'and showing the position of the parts as they form a bed.

The invention herein is an improvement more particularly upon the construction of a combined chair and'bed 'shown and described in an application tiled December 3l, 1909, Ser. No. 535,806. In the further development of said chair and bed a number ot changes have been found to be necessary to render the structure altogether convenient and desirable and at least some of these are embodied in the present application. Thus, the invention is comprised in three main portions or sections consisting of a middle section A, a buck section B and a seatsees tion C. These three sections are adapted to be folded together to constitute a chair as seen particularly in Fig. l, and to be unfolded or opened in respect to each other to form a couch or bed, as seen in Fig. 4, or in plan, Fig. 3. incident to vthis opening of the structure to constitute a couch or bed-it will be understood that the back B may bev moreor less inclined than shown in Fig. 1 to form what is known as a reclining chair, and in this connection it should be understood also that the entire structure rest-s upon a base or floor trame F upon which the middle section A ot the chair proper is engaged or released and owing tothe construction and relation of parts it was eX-w eeedmgly inconvenient to reach these hooks as wellv as its being very objectionable' toV always have this todo to make so slight aI change in the structure. Hence we have de vised the presentmeans which are convenient and etl'eetive and can be controlled from behind the chair by a small cord 2 when the spring laction ot the chair is to be restored' but which will be automatically locked by a spring 8 at, the 'front when rigidity of the" parts is desired. v To these ends we employ front and rear swinging or pivoted brace rods suspended from the seatrame AA and which have their extremities bent down at right angles to form braces 4t andv 5 respec-` tively. The braces t at the front are shorter date the ditlerences of distance between the two frames A and F at the front and rear respectively, but otherwise they are the same in construction and operation. Links va conV nectsaid braces front and rear and have slots ,6 intheir rear ends supported on pins on the braces and affording a` certainV amount ot' play between the said front and rear braces to accom modate their operations.

vIt will be noticed that the spring 5l is arranged in respect to braces 4- m such way as to exert a closing action thereon with a 'constant spring tendency and through linkse also pull the braces 5 to closing or rigid position. The cord 2 is connected' with the braces 5 and adapted to pull agalnst the spring to open position, and when the chair is to be converted into a rocker the said cord is drawn far enough'to withdraw the said braces and the extremity thereot is then engaged. on the hook or catch 7 on the back of the chair. Then as the chair is tobe made rigid again it is only necessary to release the cord and the spring 3 will draw the.' parts' to Patent-fea Nov. 5, 1912. y

supportediby rocker springs S, the idea of than the braces 5 at the rear, to accommo- Aioo` bracing position, and possibly a little rockling by hand will help braces 5 to come to rocking chair by merely handling the cord ferred to is found' in 2, the end of which is always convenient, and the springs 3 and b close the braces.

Again, in the application above referred to We found that with a structure of this kind jointed here and tiere and depending upon the opening or spreading of the end sections to getthe desired tension to the mattress M the mattress was liable to sag and did not afford as comfortable a bed as it ought to., Hence we have improved the structure by introducing a series of spring Wires W transversely of the bed between the sides thereof and engaged with the top connecting bars 9 of the mattress supporting frame comprising the posts l0 with said bars or links, Vand which is adapted to fold as before. lVhen the bed is open or stretched the mattress M is sustained from edge to edge at its middle by these cross wires, Which in a sense are incorporated-therewith and constitute a portion of the spring mechanism for carrying the bedding which comes upon the Wire mattress. These transverse Wires W run at an angle to each other from side to side of the bed and are supplemented at the front by a series of spirally wound sustaining springs G which rest upon a cross piece g in the seat frame (1.1, The' said springs Gr and lV cooperate with each other and afford all the additional spring support at the middle of the bed which is required in addition to the spring action Which the mattress M itself provides, and thus a very comfortable bed is made. he folded positiongof the several parts just described comprising the mattress M and the said -springs andthe frame 9 ,is clearly seen in Fig. 1,-where thesaid parts are `entirely removed from observation and occupy space which otherwise would not be occupied and Where they are not in the way.

A 'third distinct and material improvement herein over the application above ret-he means for making the back section B rigid with the middle section A when the said back section is 'lowered more or less to or toward its lowest attainable position as when used for a bed. In the foregoing-application a plain ratchet is shown as occupying the position relatively herein, but the said .ratchet -as said base section is liable to become detached in its engagements and particularly when the tension of the mattress M is exerted te litt the back .B from the lowered position seen in Fig. 4. rlhis frequently oet'furred, and hence in the present construction the ratchet 12 which engages on the cross portion 13 in the frame has locking notches n at its pivot end adapted to absolutely hold the head section-in the desired position when down to form a bed. For thatmatter all the notches of the .ratchet could be made in the same way with recessed ends, or their equivalent, and such notches are required when the back is lowered to an approximately horizontal position wherein it ought to be fixed rigidly with the remainder of the structure and particularly since said back should hold a given Iixed position on account of the mattress ilfhbeing connected therewith and dependent thereon to stretch the same to just the requisite tension. Otherwise the construction of the various parts herein and their operation is substantially the Same in the application above mentioned and need not be more particularly referred to.' This applies to the folding end frame la for the mattress and braces l5.

that we claim is:

l. A convertible chair and bed, in combination with a mattress therein adapted to be strctclied lengthwise and to be folded upon itself when out of use, and means to raise and support said mattress in use comprising a head section to which the mattress is attached at one end, a loldable foot section and a .pivotcd sujiport for the other end ot' the mattress in saidhfoot section adapted to swing to an elevation clear of said section, a middle section on which said l'oot section is adapted to be inverted and a pair of braces-engaging the middle ol said support and pivotcd at the top and front oi said .middle-section.

2. A convertible chair? and bed having a base section and a back, section adapted to be lowered to approximately the same p lane adapted to be inverted at the front of the base, in coml'iination with a spring wire mattress attached at one cud to said back section and a 'loldablc frame pivotally n'iountcd on the bottom ot' said seat section having the front. end ol. said mattress attached thereto, and braces for said loldable frame engaged with said base section, whereby the mattress stretched when the bed is opened. j

3. A convertible chair and bed comprising head and toot and middle sections'respectively in hinged relations, in con'lbiuation with a wire spring mattress adapted to be stretched lengthwise to form a bed and engaged at its head end with the upper end of said head section, a foldable support for and a seat section 'Lonen-1 2 l l 1 support in raised position engaged at one end With said middle section and adapted to i stretch the mattress automatically, and a double sidesupport 'for the middle of the.

mattress oldably mounted on said middle section and having side connections at its top between its front' and rear portions and having tlle'mattress attached to said .support 1o and )'oldable therewith. 1
