(on s-29) Claims.
This invention relates to sofa beds of the general type which includes a foldable bed bottom comprising a plurality of interconnected hinged sections which may be extended in horizontal alinement to form a bed or folded to form a sofa seat as disclosed in my Patent No. 2,352,989, issued July 4, 1944.
In such constructions, the outer or foot section of the bed bottom is foldable over an intermediate section to form the sofa seat while the inner or head section is movable into vertical position in a compartment behind the stationary back of the sofa.
One of the objectionable features of bed davenports heretofore in common use has been the excessive height of the seat when a bed mattress of standard thickness was used. When attempts were made to lower the seat in folded position, the sections when extended to bed position were positioned too close to the floor.
The main objects of this invention are toprovide a sofa bed having improved mechanism for supporting and interconnecting the bed sections whereby they are positioned at comfortable heights for use as a seat or as a bed; to provide a sofa bed of this kind which will accommodate a full-sized mattress of standard thickness; to provide improved locking means for holding the outer or seat section in foldedgposition overlying the intermediate section when the bed is closed to form a sofa; and to provide a sofa bed of this type which may be quickly and easily converted to eitherbed or sofa position.
An illustrative embodiment of this invention is shown in the accompanying drawings, where- Figure 1 is a side elevation, partly broken away, showing the sections in fully extended position for use as a bed. W
Figure 2 is a fragmentary plan view of the bed bottom without the mattress. 7
Figures 3 and 4 are fragmentary side eleva tions illustrating intermediate positions of the outer or foot section of the bed bottom.
Figures 5, 6, and '7 are side elevations, partly broken away, showing various intermediate positions of the bed bottom sections in their movement from the fully extended position shown in Figure 1 to the fully closed position. I
Figure 8 is a side elevation, partly broken away, showing the parts in folded position for use as a sofa seat. v
In the form shown, the improved sofa bed includes a stationary frame I, and a movable bed bottom 2 comprising interconnected hinged secin'Figurel.
2 tions 3, 4, 5, and 5, on which is mounted a flexible fabric! for supporting a matt ress 8.
The-frame 1 includes a pair of arm rests 9, and a fixed upholstered back 10 having'end bars it supported on arms [2, 13 extending forwardly from uprightwmembers M mounted on a base section I5 supported on feet I6 and providedwith upright posts I? at the two front corners thereof. Rearwardly of the upholstered back rest i0 is a space or compartment l8 for receiving the inner or head section 3: of the bed bottom when the sections arefolded into seat position, as illustrated in Figure 8.
At each end of the backrest, is a bracket l9 which pivotally supports'links 20, 2! which are also pivotally' secured to the head section 3. These links are operative to cause the inner or head sectionof-the bed bottom to move in its entirety through a fixed path of travel between its upwardly extending, folded position and its unfolded, horizontally extending bed position, as shown and described in Bayer Patent No. 2,333,087.
Extending between the posts I1 is a tubular member 22 having its ends secured tobrackets 23-mounted at the forward corners of the base l5. V The four bed bottom sections 3, 4, 5, and 6 comprise side bars having their opposed ends pivotally connected together by hinge pins 24, 25, and 26.
' The side members of the section 3 are connected to across bar 21 and diagonal braces 28 connected to the bar and offset downwardly as shown The forward ends of the side members' of the foot section 6 are connected to a crossbar 29.
Adjacent the hinge pins 26, are braces 30 having their forward ends pivotally connected to the section 6' by pins 31. Formed in the rear end of each" of the braces 30, is a slot 32 and notch 33 for receiving a pin '34 on the adjacent section 5. These bracesSOare operative to cause the intermediate section-5 to assume a vertical position normal to the sections 4 and 6 when the bed sec tions are folded to form a seat and also to serve to latch the section 6 in such angular relationship withthe intermediate section.
The lower edge of the braces 39 are notched, as shown at 35, so as to permit the braces to be lowered into the plane of the open bed sections without being obstructed by the hinge pins 26.
When the bed bottom is folded to seat position, it is concealed at the front of the sofa by a front board 36h'aving' arms 37 pivotally secured to the sidemembers of the'section' 6.
When the bed bottom is extended to bed position its inner end is supported by the links 20, 2! connected to the head section 3, and its outer end is supported on a pair of foldable legs 38 pivotally connected to the section 6, a pair of foldable legs 39 pivotally connected to the section 4, and a pair of hell crank levers 46, the lower ends of which are rigidly connected to a pivot rod 4| rotatably mounted in the tubular member 22 of the stationary frame I.
The legs 38 have pin and slot connections with a pair of links 42 which are pivotally connected to the arms 31 of the front board. The legs 39 are connected to the front board by links 43 and to the upper ends of the bell cranks by links 44. The legs 39 are rigidly connected together by a tubular bar 39' so as to operate as a unit. With this construction, the legs are automatically folded and extended by the closing and opening of the bed bottom.
At its apex, each of the bell cranks is pivotally connected to the adjacent side bar of the section 4 by means of a hinge pin 45 which engages an upstanding lug 46. On the outer end of each bell crank, is a roller 41 positioned to engage a lug 48 on the section 6 to firmly support the seat section when the bed bottom is folded as shown in Figure 8.
Extending between the intermediate sections 4 and 5 at each side of the bed bottom, is a brace bar 50 having a flange 5| positioned to overlie the upper edges of the side members of the sections 4 and 5 when the bed is open, as shown in Figures 1 and 2. The forward end of this brace is pivotally secured to the section 5 and its rear end carries a pin 52 which slidably engages a slot 53 in the side bar of the section 4.
Mounted on each side of the structure, is an improved latch bar or closing element 54, the inner end of which is pivotally connected to a bracket 55 on the section 3 by means of a pin 56 which is offset from the pin 24 whereby movement of the section 3 around the pivot 24 effects a longitudinal shifting of the latch bar. Formed in the latch bar adjacent its outer end, is a slot 51 and notch 58 for receiving the pin 52 of the bar 50. When the seat section 6 is folded so as to overlie the section 4, the brace 30 moves downwardly until the pin 34 enters the notch 33, and the brace 50 moves inwardly, shifting its pin 52 inwardly along .the slot 53. As the partially folded bed bottom is shifted into the frame, the latch bar or closing element 54 is shifted longitudinally rearwardly whereupon the notch 58 engages the pin 52, enabling the latch bar 54, acting through the braces 50 and 30 to lock the sections 4, 5 and 6 against unfolding and to draw the section 6 downwardly toward the section 4.
When the bed bottom sections are positioned as shown in Figure 5, the pins 52 are located to the rear of the notches 58 and when the sections 5 and 6 are unfolded the pins 52 move forwardly. To prevent the pins 52 from entering the notches 58 during this forward movement of the pins, the latch bars are provided with shoulders 59 adapted to engage pins 60 on the sections 4 to hold the latch bars in elevated position during the time in which the sections 3 and 4 are positioned in horizontal alinement.
In the form shown, the flexible fabric 1 which supports the mattress comprises a metal link section 6| connected to the bed sections 3, 4, and 5, and a textile fabric section 62 connected to the seat section 6.
As shown in Fig. 2 the metal fabric section BI is connected to the bed sections 3, 4. and 5 through a series of helicals, as in my previous Patent 2,352,989. In the structure of that patent, the pull of the fabric 61 and its connectin helicals is resisted in part by an intermediate tubular cross brace which is united to the opposed side frame members of the intermediate bed-bottom section. In the present structure no such intermediate cross tube is used or needed, because the pull exerted on the side members by the fabric is resisted by the braces 28 which braces also have the additional function of preserving the rectangularity of the bed section frame 3 when the latter is subjected to any unbalanced or racking stresses.
The mattress 8 is of standard thickness and is split at the center of the bed section 5 so as to facilitate folding. Ihe mattress may be tied to the supporting fabric by any suitable means.
When the structure is folded to sofa position, seat cushions 63 are placed on top of the fabric 62.
In the sofa seat position, as illustrated in Figure 8, the bed bottom is folded so that its section 5 is disposed vertically behind the front board 36, the seat section 6 overlies the section 4, and the head section 3 is disposed vertically behind the fixed back ID. In this folded position, the seat section is supported by the rollers 41 as well as by the hinge pins 26 and braces 30, and the structure is secured against accidental unfolding by the improved latch bars 54 through the links 30 and 50.
To open the bed, the cushions 63 are removed and the forward edge of the structure is raised in order to withdraw the head section 3 from the compartment I8. The bed bottom is then moved forwardly to the position shown in Figure 5. During this unfolding movement, the links 20, 2| are operative to cause the head section 3 to move in its entirety through a fixed path of travel, while the hinge pins 24 cooperate with the bell cranks 40 to guide the movement of the outer sections, and the legs 39 are automatically unfolded by the links 44 connected to the bell cranks.
During this portion of the unfolding operation, the latch bars 54 are shifted forwardly so as to disengage the pins 52 from the notches 58. The sections 5 and 6 may then be locked forwardly around the pins 25 and during this movement the pins 34 become disengaged from the notches 33 so as to permit the section 6 to pivot on the pins 26. Forward movement is continued until the legs 38 are unfolded and all of the bed sections are horizontally alined as shown in Figure 1.
To fold the structure, the sections are moved rearwardly through the various positions illustrated in Figures 3, 4, 5, 6, and 7 until they finally assume the positions illustrated in Figure 8.
Although but one specific embodiment of this invention has been herein shown and described, it will be understood that details of the construction shown may be altered without departing from the spirit of the invention as defined by the following claims.
