DAY BED.

Application filed .Tilly 11, 1921. Serial No. 483,773.

To all whom it may concern:

Be it known that I, WILLIAM E. FRANK, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Day Beds, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to day beds of the type in which the extensible section is slidingly mounted with relation to the stationary section and is arranged underneath said stationary section when it is not in use.

One object of my invention is to provide a practicable day bed of simple design and neat appearance that can be easily converted from a couch or single bed into a double bed and vice versa, and which is so constructed that the frame of the extensible section will be perfectly rigid when said extensible section is arranged in operative position to form a double bed.

Another object is to provide a day bed of the general type referred to in which the frames of the two (zo-operating sections are spaced far enough apart when the extensible section is in its inoperative position to provide adequate space between them for a mattress in the event the mattress supporting portions of said sections are composed of woven Wire fabric or a linked structure.

And still another object is to provide a day bed in which both the stationary section and the extensible section are provided with coiled or spiral springs for supporting the mattress, thereby producing a day bed that is as comfortable to lie upon as an ordinary double bed equipped with box springs and which is as comfortable to sit upon when the extensible section is not in use as an ordinary upholstered couch or davenport. Other objects and desirable features of my invention will be hereinafter pointed out.

'Figure 1 of the drawings is a perspective view of a day bed constructed in accordance with my invention, showing the extensible section arranged in its inoperative position.

Figure 2 is a perspective view of a portion of the mechanism that is used to raise proved day bed, showing the extensible section arranged in its operative position.

Figure 4 is a top plan view of portions of the spring frames of the two sections, showing one of the devices that is used to draw said frames together when the spring frame of the extensible section is raised: an

Figure 5 is a detail sectional View of the parts shown in Figure 4, taken on the line 5-5 of Figure 3.

I have herein illustrated my invention embodied in a day bed composed of a stationary section and an extensible section having mattress supporting portions formed by frames equipped with coiled or spiral springs, but I wish it to be understood that it is immaterial, so far as my broad idea is concerned, whether said frames are equipped with coiled or spiral springs or with a woven wire fabric or linked structure for supporting the mattress.

Referring to the drawings which illustrate the preferred form of my invention, A designates a frame that is combined with afoot piece B and a head piece C of any preferred construction to form the stationary section of a day bed and D designates a frame that is combined with a shiftable` supporting structure E, hereinafter referred to as a base frame, to form the extensible section of said day bed. The frame A of the stationary section maybe of any preferred construction and it can be equipped with any suitableA means that will serve as a support for a. mattress. lIn the form of my invention herein illustrated the frame A of the -stationary section, which I will refer to as a spring frame, is of oblong shape in general outline and is provided with transverselydisposed cross pieces 1 that support coiled or spiral springs 2, as shown in Figure 1, said frame being composed of two longitudinally-disposed side members 3, two transversely-disposed end members 4 and four vertically-disposed corner members 5 formed preferably from angle iron and joined together in such a way as to form a rigld frame which can either be permanently connected to or detachably connected to the foot piece and head piece B and C, respectively, of the stationary section of the bed. The base frame E of the extensible section of the bed consists ofa rigid oblong-shaped frame, con structed preferably from pieces of angle iron and combined with the stationary section of the bed in such a manner that it can be shifted laterally into a position at one side of the stationary section, as shown in Figure 3, or shifted in the opposite direction y'into the vertical plane of said stationary section, as shown in Figure 1. One'convenient way of constructing the bed is to provide the lfront side of the base iframe vE with legs 6 equipped with rollers or casters 7 and pro- 'vide the rear side of said base'frame E with upwardlyiprojecting'arms or ul'arightS 8 provided at their upper ends with hooks 9 (see Figure 1) that'lapy over and slide upon horizontally-dis`posed rails10secured to the corner members 5 of the spring frame of the stationary section of the bed. The spring frame D ofthe extensible section is similar to the springfraine ofthe stationary section, in that it consists of an oblong-shaped frame provided with transversely-disposed cross pieces 1a that support coiled or spiral springs but said spring` frame D isconibined with the base frame E ofthe extensible section in sucha'manner that it can be raised and lowered witliirelationto said base frame; When the extensible section is"inv its inoperative position, as shown in Figure 1, the 'spring frame D lies close enough .to said base frame to provide a considerable space lbetween the spring frames of the stationary sect-ion and the`4 extensible section 'of the bed, thereby making it practicableftto 4use coiled or spiral springs on the extensible section to form a support for the mattress. ln cases where the mattress supportingportion is formed by a. woven wire fabric or a linked structure1 thereis ample space between the frames A and D of the two sections to storeaway the mattress during the day when the extensible section of the bed is not in use. When it is desired to convert the bed into a double bed the base frainerl of the extensible section ispulle'd forwardly and the spring frame D of said extensible'section is moved upwardly into horizontal alignment with the spring frameA of the stationary' section, as shown in Figure 3. y' 1 Various means can be used for `raising and lowering the spring frame of the extensible section'y and for rigidly supporting said frame in its elevated position, but I prefer, to connect the spring frame Dk of the'extensible section to thebase frame E by four'p'airs of toggle links, each of which. comprises a link 11 pivotally connected at 12 tothe base frame E, a link 13 pivotally connected atlt to the spring frame Dand pivo.v

tally connected at 15 to the upper end of the link 11, and a rigid curved arm or extension 13a on the link 13 formed in such a manner that when the toggle is straightened to raise the spring frame D, the lower end of said arm 13a will bear against thel base frame E, and thus forni a rigid one-piece'strut between the spring frame D and the base frame l. ln other words, each toggle of the four toggles that are usedto raise and lower the spring frame D comprises a one-piece strut (formed by the link 13 and the extension 13 thereof) whose upper end is pivotally connected to the spring frame D land Whose lower end is brought into snug engagement with the base frame E when the toggles straighten. lt will thus be seen that while the link 11 of each toggle co-operates with the link 13 to raise the spring frame D, the weight or load imposed upon the spring frame D when said frame is elevated is transmitted directly to the base frame lknot by the links 11, but on the contrary, by the rigid extensions 13l of the links'l. When the toggles are broken or collapsed the free ends of the rigid extensions 13"L of the links 1S swing upwardly into the positionv shown in Fignrel, the spring frame 4D beingprovided with stops or laterally-projecting pins 1G against which the extensions 13'L of the links 13v strike when said spring frame is depressed.l i

i `Various means can be used for actuating the niggles vthat raise and lower the spring frame D of the extensible section of the bed, lint one means that l have found to be very ellicicnt, 'relilble and easy to operateconsists of an oscillating actuating member F rockably rmounted von vertical]y-disposed ln'ackets 1T, arranged at approximately the center of the basati-amc D and connected by pairs of links itl and 19 with the pairs of toggles arranged at the opposite ends of the be', said actnating member F preferably coiisisting of two inverted T-slnwed portions pivotally connnccted at 2O to the brackets 1K7 and having' their npwardly-projccting, vertically-disposed parts joined together by a cross piece 21, as shown in Figure r2, the links 1S beingconnected to one end of the horizontallydisposed parts of said inverted 'll-shaped vportfionsanfl the links 19 being` pivotally connected to the other end of said horizontally-disposed parts. The horizontally-disposed part of one of the inverted Tshaped portions of the ,actuating member F is nrm'ided with an integral extension or handle by means of which said member F is operated. ln practice l prefer to construct the-mcmber F in such a way tliatthe cross piece Zlof same bears against the un. derside ofthe spring frame'D of the exten-` sible ctionvolf the bed when said member turned in a direction to .raise said frame so 'that the intermediate portion ofsaid trame will be supported. by the member F, thus insuring an absolute rigid support 'for the springr traine D composed ot four pairs ot topy 'le links that support the end portions of said trame and a transversely-disposed supporting element locate-.il at the center oi said spring iframe. The links 18 and .i9 are provided with curved portions andare pivotally coinicetral to the actuating member l* in such a manner that the pivotal eonnec; tions l'ietween said parts are so arranged with relation to ilse vaxis ol: rotation ot the member lll that the links 'IS and l-l will seeurely hold the toggle links straight or in theii intended condition when the hi'indle 22 is swung to the lett into the position shown in llligure 3.

ln order to prevent the spring 'traine l) ot' the extensible section from moving laterallv with relation to 'the spring frame A oit the stationary section ot the bed, one of the longitudinal members ot the 'trame D is provii'led with devices i253 ot' sueh torni and arrangement that they will engage one of the longitudinal members ol'Y the spring lrame when the spline, 'trame D ot the extensible section is ele vated, and iih'us prevent the spring Ytraine D Atroni swa ing or moving laterally away' from. the spring 'frame A, the devices 2? having upwardly inclined portions, as shown in Figure 5. that move into engagement with the adjacent longitudinal member oi* the spring frame A when the spring 'frame D is elevated and thus tend to draw said trames together. ln other words, l do not rely upon the supporting toggles for the spring 'traine D to hold said frame rigidly in its operative position` but l provide separate devices on the Vtraine D that more inte ei ement with the traine A in si l wav to draw the 'traine D towards the Ytraine .l and hold said trame D trom swaying or `trom moving outwardly away from the traine A ot the stationary section ot the bed, As this drawing together of the 'trames D and A is effected automatically, and as the raising and lowerin of the spring Yl'raiue D of: the extensible section is effected by simply swinging a hand lever in one direction or the other, it is a very simple matler to convert the bed into a double hed or into a single bed or couch.

A day bed of the construction. above described is ineq'rensiif'e te manufacture; it is light in weight; it presents a neat appearance and when the extensible section is in operative position. it Jforms a double bed that as comfortable to lie upon as an ordinary stationary double bed equipped with box springs, due, of course, to the tact that the sining trames of the two co-operating sections are provided with coiled or spiral springs that support the mattress. When the extensible section is in its inoperative position the bed is as comfortable to sit upon as an ordinary couch or davenport, owing to the tact that the seat portion of the structure is eduippeifl with coiled or spiral springs sini to those used in upholstered couches and lilavenports.

Having thus i'lescribed my invention, what I cla-im as new and. desire to secure by Letters Patent is:
