FOLDING DAVENPORT.

Specification of Letters Patent. Patentgd June 10, 1919.

Application filed March 25, 1916. Serial No. 86,773. v

To all who) it may concern:

Be it known that I, \Viimiur E. FRANK, a. citizen of the United States, residing at St. Louis, lS'Iissouri, have invented a certain new and useful improvement in Folding Davenports. of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it'appertaiiis to make and use the same. I

This invention relates to folding davenports. couches and similar articles, and has for its main object to provide an article of the character mentioned that is easy to open and close; that is not liable to get out of order and which can be manufactured at a low cost.

Another object is to provide a folding davenport. couchor similar article of novel construction in which the back serves as a foothoard for the bed and also as a support for the front end of the mattress frame when the. article is open.

Another object is to provide an article of the charactermentioned. in which the mattress frame serves to stiffen the end frame of the article.

Another object to provide a folding daveu-port, couch or similar article in which the extensible mattress frame is held securely in its open position by XHCIIHS Of the mattresssupporting fabric. which is placed under tension or drawn taut during the operation of opening the article or converting it into a bed. I

And still another object is to provide a inattress-siipporting frame for couches and similar articles that is light and strong and which is composed of only a few rugged parts of simple construction that can be nnuiufactured cheaply and installed easily.

Other objects and desirable features of my invention will be licreinafter'pointed out.

Fig. 6 is a view similar to Fig. 5, illustratingtlie mattress cli in its operative positiou.

Briefly described, my invention consists'i-n a folding davenport, couch or similar article that comprises end frames, at mattress-sup porting means carried by'said end frames and comprising a sectional frame whose parts are hinged or pivotally connected together, a seat carried by one section of said mattress frame '.and a back carried by another sectionof said mattressframe and joined to it in such a manner that it acts as a supporting leg for the front end of thematt-ress frame and also serves as a footboard for the bed when the davenport is arranged in its openposition, theseat being preferably connected to the section of the mattress frame that 'arries same in such a manner that said seat will move into sucha position when the davenportis opened that the mattress will not strike against the seat when the mattress sags under a heavy load.

Referring to the drawings, which illustrate the preferred form of my invention, A designates the end frames of a'folding (lavenport, which end frames are prefe ably connected together by a number of cross members 1 and by a cross member 2 that serves as an auxiliary stop or support for the upper edge of the back of the daveuport whenit. is in its closed position. Theiend frames A carry a foldable mattress-supporting means that comprises a jointed mattress frame composed of a plurality of sections and a mat- 'tress-snmiortiug structure formed either of woven fabric or links 3 that are connected together and combined with coiled springs T which are secured to the end iiieinbei's of the mattress frame. as shown in Fig. 1. The jointed mattress frame above referred to comprises a rear portion or section B arranged between the end frames A and securely connected to same, an intermediate portion or section (I which is lunged or pivotally connected to the rear vsectionB in such a manner that it will lie abovesame when the davciiport is in its closed position, as shown in Fig. 3, and which is adapted to lie-swung forwardly into a position in front of the rear section B when the davenport is opened, as shown in Fig. 1, and a front portion or sect ion D which is hinged or pivotally connected to the intermediate section in the. embodiment. of my invention herein illustrated the sectional mattress frame above referred to is formed from pieces of angle iron. the rear and front sections i3 and 1), respectively, being substantially. U-shaped in outline and the intermediate section consisting of two parallel side members that form continuations of the side pieces of the end sections 13 and l) and join the same together when the davenport is in its open. position, as shown in Figs. 1 and 2.

The intermediate section (I is pivotally connected to the rear section B of the mat tress frame by pivots 5, and the side pieces of the front section ,l) of the mattress frame are pivotally connected at (i to the intermediate section 0. Said side pieces are provided with extensions 7 that lap over the side pieces of the intermediate section C and hear pon the horizontal flanges 11 on said intermediate section C when the mattress f ame is extended, as shown in Fig. l, the pivotal i'ronnections (5 between said parts being so located that the end section I) inclined upwardly slightly with relation to the intermediate section 0 when the mattress frame is extended. During the opera tion of opening the davenport the woven wire fabric or linked structure on which the mattress rests is placed under tension, and thereafter, while the mattress frame is extended, the resilient structure on which the mattress rests exerts a suliicient pull on the cross piece of the front section of the mattress frame to hold the extensions 7 at the rear end of said section tightly against the flanges 11 on the intermediate section C. When the davenport is closed, as shown in Fig. 3, the extensions 7 on the front section I) of the mattress irame project downwardly through slots 8 .in the, horizontal flanges 12 ot the rear section B, as shown in Figs. 2 and I3, and thus hold said section D in such a position that it cannot tilt forwardly or iawkwardly. The back i of the darenport carried by the front section D of the mattress trame. and is joined to said front section in such a manner that the hack F can either be arranged in front of the section i) of the frame in parallel relation to same, when the da vonport is closed, as shown in Fig. 3, or arranged at right angles to the section I) of the mattress frame, when the davenport is open, as shown in Fig. 1, so as to form a footboard for the, bed and also act as a support. or front leg for the front end of the mattress frame. ()ne convenient way of joining the hack F to the front section I) of the mattress frame consists in mounting the back I! on two pairs of

crossed links

13 and 14 which are pivotally connected to the hack F at the. ends of same and'to the side pieces of he end section I), as shown in Figs. 1, 2 and 3 This form of ace- 75 connection permits the back F to lie parallel to the front section I) of the mattress frame when the ilarenport is closed and permits the back to move bodily into a position at right angles to the section 1) when the'mattress frame is moved into its open position. The cross piece 15 of the. front section I) is provided with stops 1?), shown in li ies. 1. 5 and (3, that strike against the links 13 when the back F is moved into the position shown in Fig. l, and thus limitthe movement of the back with relation to the. section l) of the mattress frame said stops co perating with the links 13 to transmit the load on the mattress frame directly to the back i whose lower edge rests upon the loor. The links 14 operate to hold the back I in an upright or vertical position and prevent. the upper edge of same from; tilting forwardly when the mattress frame is extended. When the davcnport is closed, as shown in Fig. 3, the cross member 2 that is connected to the end frames A acts as an auxiliary stop againstwhich the back F strikes, the back I being prevented from tiltingforwardly by means of the crossed links 1 1% and H which connect it to the end section D of the mattress frame, and said end section D being prevented from tilting forwardly or rcarwardly by means of the extensions thereon that project through the slots 8 in the .tiang'es 12 of the rear section of the mattress frame.

To close the davcnport it is only necessary to lift. the. front: end of the mattress frame and swing the back F downwardly, so that it lies parallel with the front section I) of the frame, then swing. the end section D ,into a position at. right angles to the intermediate section and thereafter swing said intermediate section {1 upwardly and rearwardly, so that it lies parallel to the section it of the frame. To open the davenport the user graspsthe upper edge of the back F and pushes it forwardly, thereby causing the intermediate section C of the mattress frame to swing upwardly and forwardly on its pivots 5, the back F and the front section D of the mattress frame still remaining in a position at right angles to the intermediate section C. iet'ore the intermediate section C reaches a horizontal position the user pulls the back F upwardly so that it will be positioned at right angles to the front section-l), and thereafter said front section I) is swung upwardly so as to turn it on its pivots (5 and arrange said section in front of the intermediate section C substantially level with same, the operation of swinging the section D upwardly causing the mattress supporting fabric or structure to be placed under tension. The two sections (3 and D of the mattress frame are held substantially rigid or are prevented from moving relatively to each other by the tension of the mattresssupporting structure, and conse quently, said sections can be swung downwardly as one unit, so as to cause the lower edge of the back F to rest upon the floor, as shown in Fig. 1. In order that theseat E will be arranged the proper distance above the floor, when the davenport is closed and still not interfere with the downward movement of the mattress when the davenport is open and the mattress is subjected to a heavy load, which causes it to sag, I have connected the seat E to the intermediate section C of the mattress frame'by means of links 10 that permit said seat to move downwardly some distance below the mattress frame, when said frame is extended, as shown in Fig. 1. In this position it is impossible for even a very heavy person to miss the mattress to sag suliiciently to strike the seat. vVhen the davenport is moved into its closed position, the links 10 cause the seat E to move into engagement with the intermediate section of the mattress frame on which it rests when the davenport is closed, as shown in Fig. 3. By forming the davenport in this manner I eliminate the possibility of the seat interfering with the free movement of the mattress and the fabric on which the mattress rests. I am able to use a shallow seat and Iran arrange the seatat the usual height above the floor.

When the davcnport is in its closed posi tion the space between-the seat E and the bottom cross member 1 that joins the end frames together is closed by a rigid member 17 that is hinged to the member 1 and to the front edge of the seat, said member 17 swinging downwardly into a horizontal 'position when the davenport is opened.

Any suitabletypc of mattress clip may be used for holding the mattress in position, but I prcfcr to provide the front section I) of the mattress frame with two mattress clips of the form shown in Figs. 5 and (3. Each of said clips comprises a horizontally-disposed, U-shaped member 19 that reccivcs one edge of the mattress and a clamping device 20 pivotally connected to the top arm of said member and adapted to be turned over from the position shown in Fig. 5 into the position shown in Fig. 6, so as to securely clamp the mattress, the U-shaped member 19 of the clip being preferably formed from metal that has more or less resiliency, and the bottom arm of said member being connected to the mattress frame by a rivet 21, or in any other suitable manner.

From the foregoing it will be seen that it is a very simple matter to open or close a davenport of the construction above described, as there are no sliding parts which are apt to jam or get out of order. The back F not only serves as a substantial support for the front end of the mattress frame and as a footboard for the bed, but italso greatly improves the appearance of the davenport when it is open. The mattresssupporting means of the davenport comprises only a few parts of simple design; it is light and it can be n'nlnufzu-turcd at a low cost. Furthermore, the rear section B of the mattress frame serves to stiffen the end frames A of the davenport and tie them together securely, and the seat is connected to the intermediate section U of the mattress frame in such a manner that it cannot possibly be hit by the mattress, even when the mattress is subjected to an abnormal load. Another desirable feature of such a davcnport is that there is only one portion of the mattress that is doubled or completely folded over when the davenport is closed, as shown in Fig. In addition to the desirable features above mentioned, the mattress frame of the davenport is very rigid when it is extended, and the niattross-supporting structure is con nected to said frame in such a manner that it is stretched or drawn taut simultaneously with the operation of opening the davenport.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is:
