VFOLDABLE DISAPPEARING BED.

Application filed November 1, 1919. Serial No. 334,969.

To all whom it my concern: I Be it known that I, O'r'ro KoNRAn, a citizen of the United States and resident of Oshkosh, in the county of Winnebago and State of 'Wisconsin, have invented new and useful Improvements in Foldable Disappearing Beds, 9f w hich..the following is a description, reference being had to the accompanying drawings, which are a part of this specific'ation- 4 The present invention relates to certain new and useful improvements in beds, and refers more particularly to what may be called a foldable disappearing bed. I

One object of the present invention 1s to provide a disappearing bed hav n a foldable spring frame connected wit a supportin member, and provided with means:

Another object of my invention is to provide a novel link supporting connection between the supporting member and one of the spring frame sections, w1heireby said spring section may have a limited vertical movement, but itwill at alltimes be parallelwith reference to the supporting member.

A further .ob'ect of this invention is to rovide a slidable supporting member formin what ma ceiving the olded spring frame sections, and carrying the same into a concealing recess, the outer side or face of said supporting member forming a part of the outer face of the wall surrounding the concealing recess.

A still further object of the present invention is to provide a disappearing bed including a supporting member and a spring frame having two hingedly connected together sections connected with the support ing member and having means for elevating one of said sections when they are extended, and locking the same in extended position and means for collapsing and disposing the be termed a drawer for respring sections within the supporting member when they are moved to folded position. A more specific object of this invention 18 to provide a brace bar for the spring frame where its sections are connected 'together, which is offset to accommodate for the sagging of the spring, and which has means or guid ng its offset portion when the spring frame is nested 'within its supporting member.

With the above and other which will appear as the, description proceeds, my invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the ap-. pended claims, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claims.

In the accompanying drawing, 1' have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have objects in view so far devised for the practical application of the principles thereof, and in which:

'Fig. 1 is a; perspective view of a davenport in connection with which my invention is employed, the spring frame being ..illustrated as nested within the supporting member, and the supporting member beingshown as partly moved to its position outwardly thereof.

Fig. 2 is a perspective view thereof illustrating the bed as inoperative position. i. e.-,' with the supporting member exteriorly of the davenport, and the spring frame sections unfolded or in extended position, said view having parts broken away to more clearly illustrate the various details of my invention. I

Fig. 3 1S an enlarged fragmentary sectional View illustrating the novel guide means for the offset portion of-the intermediate sprinxr frame brace rod, said view being taken on the line 33 of Fig. 2.

Fig. 4 is a side plan view of my invention illustrating the various parts thereof as in folded position and nested within the drawer-like. supporting member which is shown in its outward position, and Fig. 5 is the side plan view thereof illustrating the parts as in their operative position.

My invention is adaptedto be folded or nested within a' drawer-like supporting member '6 which includes a substantially rec-' of a davenport as illustrated in Figs. 1 and 2. In either case the outer end of the supporting member 6 has secured thereto a board or partition 10 shaped and finished to conform with the exterior appearance of the wall, davenport or the like, in which the bed is adapted to be concealed, and also has secured to its outer end suitable sup-porting feet 11,- so that its outer end when outwardly of its concealing recess will be maintained substantially level with its inner end.

The supporting member 6 has pivoted to each side thereof in space relation as at 12 the lower end of a pair of links 13 having their upper ends pivotally connected with the lower ends of like links 14 having their upper ends pivoted as at 15to the adjacent side of a bed spring section 16. Each pair of connected together links 13 and 14- have secured thereto adjacent their outer ends as at 17 the outer ends of links 18 having their inner ends pivotally connected together as at 19, each set ofconnect-ed together links 13 14 and 18 forming what may be termed one section of a lazy tong. The pivots 20 of each pair of connected together links 13 and 14 are connected together and maintained in space relation by an intermediate bar 21 as best shown in Figs. 4 and 5 and the pivots 19 of the links 18 have sliding engagement within slots 22 formed in. said bar 21.

As will be readily obvious this structure maintains the spring structure 16'at all times parallel with the supporting frame 7 but at the same time permits its ready vertical movement so that the frame 16 may be nested tolie against the frame 7 or may be releasab-ly locked or held in raised position as depicted in Fig. 5 by means now about to be described. 4

Pivotally connected as at 23 to the spring frame section 16 is a complementary spring frame section 24 which is readily movable on its pivots 23 to the folded position depicted in Fig. 4 or to the extended position depicted in Fig. 5 in which position its outer end is supported by a foldable support 25 to be later described and its inner end supported by the section 16.

As will be readily understood the adjacent sides of the section 16 and the frame 7 are connected together by the means of the links before-described and as their operations are identical but one side will be hereinafter referred to. The innermost pair of link members 13 and 14 have pivotally connected with their pivot 20 the inner lower. end of an operating or locking bar 26 which has its outer upper endpivoted as at 27 to the adjacent side of the section 24 near its pivot 23, but so positioned on a plane beneath that of the pivot 23 that when the section 24 is in its extended position said pivot 27 will lock the link structure before described and retain the same against collapsing. The bar 26 besides locking the links in their ex tended position as depicted in Fig. 0 provides the means for raising and lowering the section 16 to operative position or to its position nested within the drawer formed by the supporting member.

The operation of this link structure is substantially as follows:

Assuming the spring sections 16 and 24 to be in folded position as depicted in Fig. 4 the section 24 is swung on its pivots 23 when it is desired to place the parts in position for use. This movement of the section 24 moves with it the bar 26 which exerts a forward pull on the pivot 20 of the innermost link members 13 and 14 which having their outer ends pivoted to the section 16 and supporting frame 7 arenot permitted of forward movement and following the line of least resistance will raise the frame 16 to the position depicted in Fig. 5. The links 18 will also have the distance between their pivots 17 increased and the upward movement of the section 16 will be limited by the pivots 19 striking the inner ends of the slots 22. hen the section 24 reaches the fully extended position the pivot 27 of the bar 26 will drop below the pivot 23 between the sections 16 and 24 and thus lock the links 13 and 14 in their extended position as any weight which is placed upon the bed springs which will naturally tend to collapse the links will merely place a strainupon the bar 26 as will be obvious.

The support 25 for the outer end of the section 24 consists of two supporting legs 28 formed of angle ironand having their upper ends pivoted'to the section 24 as at 29 and the legs 28 are connected together by means of a brace 30. The legs 28 are" permitted a free movement to fold against the under side of the section 24 but are limited in their outward movement to a position just outwardly of an imaginary line drawn vertically through the pivot 29 so that weight placed upon the spring will not tend to collapse the same. \Vhen the sections 16 and 24 are folded together support 25 is folded I against the under side of the section 24 which is. its top side when in folded position as best shown in Fig. 4. g

The spring frame is braced adjacent the pivot 23 by means of a rod 31 having its ends pivoted as at 32 to one of the spring sections and the brace rod' is provided with an offset portion 33 intermediate its ends so that the same will be out of the way of the give of. the spring 34 carried by the sections 16 and 24. Were the ofi'set portion of the brace rod 31 to be free considerable inconvenience would be experienced in folding the bed so I provide a means for guidance to prevent its interference with the. functioning of the other parts of my invention, which means includes a' guide link 35 havin a pivotal connection with a link 36 secure to the outer end of the supporting member 6 and a pivotal connection 37 with the offset portion 33 of said rod. Theoperation of this will be at once apparent as when the section 16 is. lowered by the means hereinbefore described the member 35 will guide the lower end of the offset portion, 33 inwardly to the position depicted in Fig. 4.

From the description taken in connection withaccompanying drawing it will be at once apparent that I provide a disappearing bed which may be concealed within the walls of a room, or else be concealed within the bottom of a davenport. In the latter the seat of the davenport forms no part of the bed as is the case of structures of this class now in use and therefore the davenport may,

be provided with the best of finish without danger of being damaged by constant use as a bed.

What I claim for my invention is:

prising a supporting member, a spring frame including-two connected sections, pairs of pivotally connected together link members having their outer ends pivoted to the supporting member and to one of the frame sections, a second pair of pivotally connected together link members carried by each pair of first mentioned link members and having their outer ends pivotally secured thereto, and means operable, by movement of the other frame section to raise and lower the first mentioned frame section with respect to the supporting member.
