This invention relates to folding beds and more particularly to a collapsible bed con struction incorporated in seating furniture, such for example, as in sofas or davenports for the parlor, living-room and the like.
One object of the invention is to provide upholstered seating furniture of improved construction which is readily convertible into a comfortable bed, the bed portion being normally concealed within the framework of said furniture and forming a novel foldable structure which shall be easily installed as a unit into 'the framework of the furniture n for operation without interfering with, mar- Y improved construction having a tension spring mattress support stretched on a foldable frame work forming a rigid structure when either folded closed or unfolded open.
A further object of the invention is to provide a bed convertible seating furniture of the character described including a bed portion comprised of few and simple parts assembled to form a. compact foldable structure, which may be easily and quickly openn ed to provide a rigidly supported comfortable bed, which shall require a minimum effort on the part of the user in converting said furniture from a seat to a bed, and vice versa, and which shall be relatively unexpensive to manufacture, and practical and eflicient to a high degree in use.
Other objects of this invention will in part be obvious and in part hereinafter pointed out.
The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the constructionhereinafter described and of which the scope of application will be indicated in the following claims.
In the accompanying drawings, in which is shown one of the various possible illustrative embodiments of this invention,
Fig. 1 is a side view of a convertible upholstered sofa constructed to embody the invention showing the bed portion in opened up position, a portion of the sofa frame and upholstery being broken away to expose the bed portion structure.
Fig. 'Q is an end elevational view of the improved bed portion shown in folded position under the sofa seat, frame parts being shown vin dot and dash lines.
Fig. 3 is top plan view corresponding to Fig. 1 partly shown broken away, and
Figs. 4 and 5 are fragmentary views, as seen on lines 4-4 and A5---5 in Figs. 4 and 1, respectively.
Referring in detail to the drawings, 10 denotes a bed convertible sofa constructed to embody the invention. Saidv sofa may comprise frame member corne-r uprights 11 terminating in legs 11a; for supporting the lsofa on the floor surface S, side stretchers 12, joining said uprights 11,'.suitable upholstery including a back rest 13 applied over the frame members in any well understood manner, a removable upholstered seat 14, and a bed portion, indicated generally at 15, adapted to be foldably mounted within the sofa frame members under the seat 14. The latter swings with movable parts of the bed portion 15 when said sofa is opened up to provide a bed in the manner hereinafter described.
The bed portion 15 is preferably made entirely of metal, as for example forming a steel collapsible structure which can be installed as a unit in the sofa framework and is seen to comprise an inner end section 15a, an outer end section 15b, and an intermediate section 150 hinged at 15d to each of said end sections. Said sections may also include a continuous spring tension mattress support 16 of the flexible resilient stretched 'fabric type. These sections with the fabric spring permits forming a compact collapsible structure which is relative by light weight yet strong durable and adapted to withstand rough usage.
To mount the bed portion 15 within the sofa framework, angle member 17 may be provided, which extend between the rear and front stretchers 12 just above the legs 11a. Each membel .l has a suitable hanger portion 18 adjacent the rear end thereof, and as here shown said portion is provided with a slot 18a detachably engaging with a hook 19 which is fixedly secured to the side stretcher 12. The front end of each angle member 17 may be upturned to provide a hanger portion 20, and a slot 20a in one side of the angle may be provided fordetachably engaging with a hook 21 secured in the front end of the side stretchers 12. The other side of the angle of hanger portion adjacent the slot 20a may be drilled to receive wood screws 22 for fastening to the front stretcher 12 as is clearly shown in Fig. 1. A cross strap 22, may be provided to serve as an additional bracing for the hanger portion 20 with the memberj17 For swingably mounting the inner end section 15a on the members 17 there is yprovided two sets or pairs of spaced links 24 and 25. The inner or rear pair of links 24 have one end of each pivoted at 26 to the section 15a outwardly from the inner end thereof and are pivoted at 27 to the members 17. Said links 24 extend down through slots 17a in members 17 and beyond the latter, terminating in suitable attachments 24a for the ends of the rear hanger portions 18 as shown in Figs. 1 and 2. The front pair of links 25 have the lower end of each pivoted at 28 adjacent the hanger portions 20. The upper ends 25a of said links are extended beyond the section 15a and may be pivoted to the latter at 29, said link ends 25a serve as supports for pivoting, at 3Q, bracket arms 31 which interconnect `the link ends 25al with pivots 32, the latter being positioned midway between pivots 15d on intermediate section 15e.
The hanger portions 20 may terminate in stops 205 against which the links 25 abut for retaining the latter in upright position when elevated on opening the bed portion 15.
One end of each suspension link 33 is also pivoted at 32, the other end of the link 33 being pivoted at 34 to an end of an angle inner brace 35 secured by suitable means, such as screws 3G, to the seat 14 for supporting an end the seat 14 when the bed portion is in open position as shown in Figs. 1, 3, and4. Y
A pair of spaced hinged leg stanchions 3 may be provided for the bed portion 15, each stanchion being pivoted at 38 to an angle bracket 39 carried by the brace 35 on the end opposite the pivot 34. The upper end 37a of said stanchion extends beyond the section 15?), and may be hinged to it at 40. Said stanchion ends 37a serve as supports for pivoting at 41 bracket arms 42 interconnecting the stanchion ends 37a with pivots 43 provided on a mid portion on the intermediate section lc'adjacent the pivots 32.
For stiflening the bed portion 15 and for bracing the sections against the tension action of the spring mattress support 1G, the end of the outer section 15b is provided with a strut 44 which may be formed of a pipe flatened at the ends and secured in position in any suitable manner, as by means of rivets 45. Extending lengthwise the bed portion and connecting with the intermediate section 150, there is provided a strut 46 having off setting of the ends 46a of said strut 47 provides a clearance for the middle of the spring mattress support 16.
Upstanding from the outer end of the section 15b adjacent the ends of the strut 44, spaced bars 47 are secured. Said bars serve to retain the folded sections in relatively fixed spaced position for rigidly supporting the seat 14, on the portion 15 when the latter is closed, the ends of the bars 47 being adapted to engage with the angle member 17 as is clearly shown in Fig. 2.
If desired, one or more foldable pillow rests may be provided, and as here shown each rest may comprise a U-shaped member 48 having the ends 49 thereof hinged to the bar 47, and other spaced upright support 50 secured to the section 15b. A suitable spring 51 may be anchored to the section 15d and connect-ed withthe U-shaped member 48 by means of the strap 52 for holding the rest in an upright or collapsible position.
The movement of the parts of the bed portion 15 during the opening and closing thereof will now be apparant. lVith the combination bed-sofa 10 constructed and assembled as described above and shown in the drawings the parts when positioned with the bed portion 15 open as shown in Fig. 1. may be closed by first swinging the head support down so that the U-shaped member` 48 lies against the Vbed spring support 1G. The spring 51 assists in retaining the pillow support rest in its down folded position. Next the seat 14 is raisedand the section 157 folded over at the same time applying pressure for moving the bed portion 15 toward the back rest 13. This will cause section 15a to swing down on the links 24 and 25 to the position shown in Fig. 2 and the seat 14 will be positioned rigidly supported in its proper relation with respect to the back rest 13. The spring 60 prevents the sections from accidentally folding closed and serves to provide smooth and even opening and closing operations.
To convert the sofa 10 to a bed, the seat 14 is drawn out of its normal position on the folded bed portion 15 and swung from the position shown in Fig. 1 to that shown in Fig. 2. Said seat carries with it the foldable sections.
It should be noted that when the bed portion 15 is open the section 15a. is spaced from the back rest 13. In order to prevent any of the bed clothing or the person reclining on the bed portion from accidentally passing into the space between the end of said section 15a and the back rest 13, a suitable guard rail 53 is provided. Said rail extends the length of the bed and has its ends supported on the corner bars 54.
The bed portion l5 can obviously be constructed as an individual unit, and manufactured in iron working factory, independently of the upholstered sofa portion and the two portions may then be readily assembled to provide the improved combination of the bed convertible sofa embodying the invention.
It will thus be seen that there is provided devices in which the several objects of this invention are achieved and which are well adapted to meet the conditions of practical use.
As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
Having thus described my invention, I claim as new and desire to secure by Letters Patent:
