FOLDING BED.

Application filed April 8, 1925.

This invention relates to improvements in folding beds and has as one of its objects to provide a bed which, when not in use, may be folded to very compact form so as to occupy'but'little space in the room in which it is 'to be located, and which may be readily unfolded or extended so as to provide a full sized bed.

Another object of the invention is to pro-- vide a folding bed so constructed that when folded there will be no tendency for it to "unfold;

Another object of the invention is to provide a folding bed so constructed that when set up for use and occupied, there will be no tendency whatsoever for the bedto collapse but the structure will, on the other hand, he as substantial a rigid bed of the ordinary t1 e.

rluother objectof the invention is to provide', in a folding bed, a spring bottom of novel construction adapted to be automatically folded or collapsed when the bed as a whole is folded;

Another object of the invention is to so ns r c the pring bo t m of th b tha it p s ss sea r sil e cy a d Pr sent a substantially flat and smooth supporting.

preferably interposed between the intersecting portions of the bars 2, and arranged upon the studs 4, and washers 8 and cap nuts ,9 being fitted onto the outer ends of the said studs to holdthe bars properly assembled.

At this point, it will be evident that the two sides of the bed can be collapsed by shoving against one end of the structure, the other end be ng disposed against a wall surface, and, on the other hand, the structure can be unfolded or extended by pulling upon one end thereof. The cross rails 6 serve, of course, to connect and properly space and likewise relatively brace the two sides of the structure, and in order to provide against complete extension of the structure or, in

neath the series of rails. By reference to Figure 4 of the drawings, it will be observed that when the structure is folded, the portions of the straps 10 which extend between relatively adjacent ones of the rails, .6, will be permitted to sag so that when the structure is extended as shown in Figure 1, the straps will be taut.

In order to provide the head 11 and foot 12 of the bed, a pair of the bars 2 at the head end of the structure are extended upwardly a suitable distance,as indicated by the numeral 13, and the upper ends of the extended portions are connected by a cross rod 14:. A brace rod 15 is preferably anchored at its upper end in the cross rod midway between the ends thereof and secured at its lower end, as at 16, to the rear side of the 'rearmost one of the rails 6. sheet of cloth material 17 is provided. at its upper edge with a hern 18 which encloses the cross rod 14:, and the lower edge por tion of this sheet of materialis secured along the rear side of the said rearmost rod 21 which extends between thenpper ends of the extended portions of the end bars 2 at thisend or the structure. The

sheet 19'is; secured at its laws edge along the for\ ard side of the foremost one of the cross rails G, as indicated by the numeral 23.

The spring bottom of the bed is composed of a number of relatively broad and sub stantial leaf springs and the numeral 24; indicates a series of such springs which are arranged at the foot end 12 of the bed struc ture. Each of these springs 2a has its forward end portion turned downwardly at right angles to its body portion as indicated by the numeral 25 and thence forwardly at right angles to its portion to provide an attaching portion 26 which secured by screws or other suitable fastening elements 27 to the upper side of the foremost one of the cross rails b, the springs extending rearwardly from this cross rail in a sligl'itly eleat-ed position and being so constructed and arranged as to incline slightly upwardly and rearwardly from their attached. ends. The springs 24, are arranged in a transverse series and their free end portions extend above and in spaced relation to the next adjacent one of the cross rails 6, as best shown in Figure 1. The numeral 23 indicates another series of springs each comprising a supporting spring 29 which is relatively short and secured at one end as at 30, to the upper side of that one of the rails 6 which is located immediately in advance of the rearmost one of said rails, the said short spring 29 being curved upwardly and rearwardly from its attached end and being riveted or otherwise secured as at 31, at a point near its rear end, to the under side of another spring leaf 32 which is relatively broad and longer than the spring 29. The point of attachment 31 is located nearer the forward end of the leaf 32 than the rear end thereof and the rear end of certain of the leaves 32 are bent to provide sleeve portions 33 which lit about a cross rod indicated by the numeral 34, this rod serving to relatively brace the springs and prevent displacement .of their rear ends. The other ones of the spring leaves 32 have their rear end portions bent downwardly substantially at right angles as indicated by the numeral 35, and thence upwardly upon themselves at an acute angle to the portions 35, as indicated by the numeral 36, the rear ends of these leaves being designed to rest upon the rearmostone of the cross rails 6, as best shown in Figure 1 of the drawings. Each of the other cross rails 6 supports a series of cushioning springs each indicated in general by the numeral 37 and comprising a relatively short leaf 38 corresponding to the short leaf 29 of the spring 28 previously described and secured at one end as at 39 to the upper side of the respective rail 6 and being bent to extend upwardly and rearwardly and secured at its rear end to the under side of a spring leaf lO corresponding to the spring leaf 32. The rear ends of the spring leaves 40 extend above the cross rails 6 in rear of the rails to which their respective suj'iporting springs 38 are secured and it will. be observed that the springs, throughout the entire assemblage, are so arranged that the rear end of each spring will overlap the rear end of the spring leaf innnediately in rear thereof; It will be evident at this point that when the bed is occupied and pressure is exerted upon the springs, they will be forced downwardly and the weight will be sustained firs by the supporting springs 29 and 38 and, if sufliciently heavy, will bring the front and rear ends of the spring leaves 32 and 40 and the rear ends of the saring. leaves as into bearing engagement witi the upper sides of the rails or, more specifically, the ends of the springs which are secured to the rails. Thus, a very substantial and yet perfectly pliable and resilient bed bottom is provided which will be comfortable and present a yielding supporting surface substantially uniform throughout.

Referring to Figures 1 and 4 of the drawings, it will be observed that when the structure is collapsed by shoving against one end thereof, the other end being disposed against a wall surface, the free ends of the spring leaves will slide over the leaves in rear thereof, the rear end of one of the leaves 32 riding against the rod 15 and the cross rails 6 being partly rotated until the spring leaves assume substantiall the position shown in Figure 4:, in which position they will be more or less upright and will be housed between and concealed by the head and foot sheets 17 and 19.

It will also be evident from the foregoing description and accompanying drawings, that the bed will be exceptionally substantial inasmuch as the lower ends of all of the bars 2 rest upon the floor surface.

If desired, the spring leaves 32 and 40 may be made of resilient slabs of wood and be supported by the respective supporting springs 29 and 38.

Having thus described the invention, what I claim is: y

1. A bed bottom comprising a plurality of spaced parallel bars, a plurality of leaf 1 springs disposed above the bars in spaced relation thereto having adjacent ends overlapped in vertical line with the respective bars and short springs connected at one end to the bars and at the opposite end to the respective leaf springs, said short springs being offset intermediate their ends.

2. A bed bottom comprising a plurality of spaced parallel bars, a plurality of leaf springs disposed above the bars in spaced relation thereto having adjacent ends overlapped in vertical line with the respective bars, the outer ends of the leaf springs at one end of the bottom being bent vertically and laterally and the outer ends of the leaf springs at the opposite ends of the bottom having certain ones formed into sleeves and others bent to rest upon the adjacent bar, a rod supported in the said sleeve and engaging under the corresponding ends of the adjacent springs, and short springs attached at one end to the intermediate bars and at the opposite end to the underlapping ends of the leaf springs.

3. A folding bed comprising lazy tongs sides, the end members being extended to provide head and foot sections, cross bars pivotally connecting the bars of the lazy tongs and supported thereby, closely related leaf springs connected at one end to the respective cross bars and overlapping in vertical line with the respective cross bars, a transverse rodengaging the free ends of the leaf springs at one end of the bed, a guide rod forming a brace at one end of the bed and adapted to coact with the said transverse rod to effect a folding of the springs, and means for limiting the extension of the bed when adjusted for use.

45A bed including extensible and colla sible side members, cross rails extending etween the side members and supported thereby for rotative movement, a cross rod extending between the side members at one end of the structure, a guide rod extending between said cross rod and the adjacent end one of the cross rails, and a series of leaf springs supported at their ends by each cross rail, the free end portions of the springs of each series overlapping the supported ends of the springs upon the next adjacent cross rail, one spring of one of the'series having its free end positioned to coact with the said guide rod in the collapsing of the structure to effect upward swinging of the said spring and a consequent rotation of the cross rail by which it is supported and upward swinging of the other springs upon-said cross rail, whereby to elevate the 'free ends of the springs of successive series to collapsed position.

In testimony whereof I afiix my signature.
