T0 all whom t may con-cera.'

Be it known that I, JOHN M. RroHAnD- soN, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of lVisconsin, have invented certain new and useful improvements in Davenports; and i do hereby declare. that the following is a full, clear, and exact description thereof.

This invention relates to improvements in foldable couch beds of the davenport or day-bed type, in which a section of bed frame is normally housed beneath the seat, which seat serves as an extension to the bed frame section when swung to its inverted position before the couch.

The primary object of the present invention resides in the provision, of a simple andV economical structure of the above character, that is capable of use in connection with a hair spring mattress, heretofore considered impractical for the reason that a mattress of this type cannot be folded, and consequently its proper housing beneath the seat has presented serious diiiiculties.

Incidental to the foregoing, a. further object resides in the provision of means for automatically shifting that portion of the mattress supportedl on the section of bed frame which is normally housed beneath thel seat. A more specific object is to provide a simple structure of counterbalance adapted to serve as a cushion, for the folding parts at the end of their folding movement, and to initially assist in the extending operation.

A still further object is to provide a convertible couch structure which is detachably connected: to the couch frame and may, therefore, be readily detached for shipping, repairing, and so on.

W ith the foregoing and other objects in view, the present invention consists of what is herein shown and described and more particularly pointed out and defined by the appended claims, it being understood that various changes and modiiications in theY structural details are Vcontemplated as within the invention.

ln the drawings Figure 1 is a plan view of a davenpert constructed within the plans of the present invention, parts ofthe davenport frame being in section to more clearly illustrate the strucural features.

Figure 2 is a transverse sectional view taken on the line 2*-2 of Figure l, and illus- .trates the various parts in their bed-forming position.

Figure 3 is a similar view illustrating the parts in one of their intermediate positions.

Figure 4 is a similar view illustrating another intermediate position.

Figure. 5 is asimilar view illustrating the parts in their couch-forming position.

Figure o is a detail sectional view taken on the line 6 6 of Figure 5.

vFigure 7 is a detail sectional view taken on the line 7 7 of Figure l.

Figure 8 is a detail sectional view taken on the line 8-*8 of Figure l.

Referring now more particularly to the accompanying drawings, wherein the present invention is illustrated in connection with a bed davenport, the numeral 1 designates a pair of end standards connected at the rear by a stationary upholstered back 2, and at their front by a face board 3, to form a davenport frame. Pivoted between rthe end standards l, adjacent their front ends, is a seat section 4, which, when folded to couch-forming position, as illustrated in Figure 5, supports an upholstered cushion A., preferably of the hair spring type, the same being indicated in dotted lines. Secured to the sides of the seat section 4, adjacent its pivoted end, are a pair of brackets 5, to which are pivoted at 6 a pair of ears 7, that in turn carry an inner bed-frame section 8, preferably constructed of angle iron, to form a skeleton frame. Secured to the ears 7 are a pair of plates 9, adapted to abut the brackets 5, thus serving as a stop to maintain the seat section 4 and bed frame 8 in alignment, when the davenport is being converted into its bed-forming position, as illust-rated in Figures 2 and 3.

From the foregoing description, it will be seen that, as the seat section 4 is swung outwardly from its couch-forming position illustrated in Figure 5, the forward end o vthe inner bed frame section 8, which is pivyotally connected to the seat section 4, will hinged connection with the seat section, l provide 'a pair of spring control latches 10, which are pivotally connected to the brackets 11, secured to the end standards 1. The latches 10 are held in their normal position against the stops 12 projecting from the brackets 11, by means of the springs 13. Cooperating with the latches 10 are a pair of brackets 14, secured to the sides of the bed frame 8, adjacent its inner end, the brack ets 14 being provided with lateral exten' sions 14, which extensions, upon upward movement of the bed frame 8, will wipe past the latches 10, and when the bed frame section 8 has been raised to its bcd-forming position, illustrated in Figure 2, the latches 10, by means of the springs 12, are caused to swing under the extensions 14 and support the same.

lt is further obvious that, upon initial movement of thek seatmember 4 from its bed-forming position, the hinge joint between it and the bed frame 8 Vwill 'break and the inner end of the bed section will be forced rearwardly until the lateral extensions 14 drop oif of the latches 10, after which, further swinging movement of the seat member 4 will cause the inner end of the bed frame section to move downwardly until the lateral projections 14 engage the supports 15, secured to the end standards adjacenty their lower portion, as illustrated in Figure 3. V.b`i`iiirt-lier movement of the seat member 4 to the position illustrated in Figure 4 will cause the joint between the seat and bed frame to break, and as this movement takes place, it will be seen that the inner end of the bed frame section 8 is slidably suppo-rted by the elongated supports 15, thus compensating for the movement of the bed frame section.

As set forth in the objects of the invention, one of the primary features of the present construction is to provide a structure capable of use in connection with a mattress of the hair spring type, which, due to its rigidness, cannot be folded for the purpose of housing beneath the seat when the latter is folded to its couch forming position; Therefore, in o-rder to utilize this type of mattress, l propose to construct the samein two parts, one of which is to be housed beneath the seat member, while the other, which has been previously described,

lsused as an upholstered seat for the davenport in one instance and as a portion 'of the bed mattress when the davenport is converted into a bed. Because of the limited dimensions of the `davenport, as .compared with the length of the mattress required for a'bed, it is essential to provide means for shifting that portion of the mattress housed beneath the seat, in ordery to permit folding of the seat member with relation to the bed frame section 8. This is accomframe 8, said auxiliary support having its Y Vinner end 17 turned upwardly to retain that portion of the mattress B supported thereon.

Due to the difference in dimensions between the sections of mattress necessary to form the bed, and the bed frame section 8 and seat member 4, it will be seen, as illustrated in Figure 2, that a portion of the m'attress B is supported 0n the seat member 4j It is therefore necessary to provide an extension 18 for the seat member 4 in order to properly support the remaining section of the mattress A. This extension is held in telescopic relation to the seat member 4 by means of the guides 19, extending over the upright portions of the angle irons 20, which form the sides of the'extension. The guides 19 are formed integrally with the plates 21, secured to the sides of the seat member 4, and to which are pivoted a pair,V

of legs 22, having their upper end connected to the ears 7 by means of the links 28. The

links 23 not only serve to collapse and ex-Y tend the legs 22 upon the movement of the seat member, but are also utilized for the purpose of automatically shifting the auxiliary mattress support 16 as the associated parts are moved to their various positions. This latter opeiation is accomplished by means of the links 24 pivotally connected to the links 28;.at one end and secured to the ears 25 at their other end, said ears being secured to the sides' of the auxiliary mattress support 16. Y v

rllaking up the operation ofconverting the davenport into a bed, attention is directed to Figures 5, 4, 3 and 2 in the order named. The first step necessary is to remove the mattress section A. from the seat inember, after which the latter is gripped by the strap S, secured to its inner end, and raised to the position illustrated in Figure 4, duriing which movement the legs 22 'are-swung on the seat member to their supporting position by means of their linked connection with the bed frame section 8, and simultaneously with the foregoing action, the mattress support 16 will be retracted on the bed frame 8 by means of its linked connections' 24, thus causingthe mattress to be shifted forwardly until its inner end will clear the upholstered back, as the bed frame is swung upwardly. The extension 18 is then .manually slid outwardly and the mattress section A placed thereon adjacent to sectionrB,

thus forming a complete mattress of ample dimensions. v

For the purpose of initially assisting in the raising of the seat member from its couch position, I provide spring controlledV levers 27, pivoted to the plates 28 which are secured to the end standards ladjacent their rear edge. In the folded position of the seat member, illustrated in Figure 5, the levers 27 engage the angular brackets 28, carried by the angle irons 20 of the extension 18, and inasmuch as the springs 27', which actuate the levers 27, are expanded in this position of the levers, it is obvious that a slight pull on the seat member 4 will cause it to raise with little effort, being assisted by the levers 27. It will be further seen that, upon completion of the folding movement of the seat member, to its davenport position, the angular braclfets 28 will be engaged by the levers 27, which cushion the holding movement and insure the retraction of the extension 18, thus preventing the same from becoming accidentally extended. When in closed position, the seat member 4 is supported by means of the brackets 29, which engage extensionsBO, formed integrally with the plates 11.

To facilitate removal of the foldable parts from the davenport frame, I provide a detachable pivotal connection between these parts, which comprises a pair of plates 31, connected to the end standards and provided with notches 32, which are adapted to receive the headed pivots 33, carried by the brackets 34, that are secured to the sides of the seat member 4. Thus it is obvious that, by loosening the front connection between the end standards 1, the foldable mechanism, including the seat and bed frame sections, can be readily removed from the main frame.

Attention is further directed to the adaptability of the present invention to a couch bed of the day-bed type, in which instance, due to the greater width of a day-bed, the seat and bed frame sections can be increased in width to accommodate the section of mattress, without necessitating the extension 18 and the shiftable mattress support 16,- otlierwise the structure remains the same. It will also be noted that very little effort is required to convert the structure from one position to another, due to the fact that the seat and frame section serve as a counterbalance for one another, with the exception of the initial opening movement and the end of the closing movement, at which time the load is relieved by the counterbalance levers 27.
