. COLLAPSIBLE BED.

Application filed January 25, 1922. Serial No. 531,585.

My invention has reference more particu larly to abed structure comprising two sections, which may be nested. one within the other to form a single bed or davenport, or may be extended to afl'ord a double bed, or completely separated, thus fornnng twin beds.

Beds of this type heretofore have had the movable section arranged to slide under the mattress supporting surface, or spring frame of the stationary section, and as the mattress was usually doubled over on the stationary section toward the side from which the movable section is withdrawn, it was necessary to lift the entire mattress in order to fold or unfold same. Moreover a flounce or drape is usually provided on the mattress to hang down along the ends and outer SlClGOf the collapsed bed, and in previous structures thls was in the way and liable to become caught in the moving parts and had to be stralghtened out each time the bed was extended or collapsed. It has also been the prevlous practice to provide supporting legs for the movable section only at the outer side, the inner side being slidably mounted on the stationary section.

In my construction the upper section 18 movable so that the doubled overmattress is pulled out with this section, and it is merely necessary to lay the top fold of the mattress back over the stationary section in extending the bed, and vice versa in collapsing the structure, thus avoiding the necessity of lifting the entire mattress as in pre vious bed structures of asimilar character.

Moreover as the fiounce is attached to the lower fold of the mattress which latter moves with the movable section. the fiounce is not disturbed by the extending or collapsing of the bed structure, nor by the folding and unfolding of the mattress, and there is also no danger of the fiounce becoming caught in the moving parts.

Another important feature of my construction is that neither of my Sections depend upon the other for support, but each is constructed in the form of a complete selfsupporting cot which interlocks with the other to form the extensible bed but maybe readily separated and used independently as a separate cot.

Other features or objects of my invention have to do with facilities for insuring direct in and out movement of the movable section 1 and there so that the latter may be grasped atany point and. easily adjust-ed without danger of cramping or. binding between the sections,

are also other features of improvement embodied in my invention which will appear from the following detailed description thereof.

Fig. 15, asection view on the line 15-15 the angle iron being notched at the juncture I of the legs 3 with the intern'iediate portion 6 to effect the bond and afford. a iuitre fit. A corner brace 7 connects each leg with the intermediate portions 6 as shown.

The side rails 4 which are preferably of angle iron are positioned a suflicient dis ,t-ance below the upper ends of the legs 3 so as to afford ample clearance below the spring structure 8 which extends between the intermediate or top portions 6 of the end frames and there are corner braces 9 between the side rails and legs 3 as shown. The spring structure 8 which supports the mattress is preferably of woven or link wire fabric and has a number of helicals 10 at each end connected with the top portion 6 of the corresponding end frame to hold the spring structure under the required tension, and in order to brace the end frames against the strain of the spring structure and the supported weight, the brace rods or bars 5 are positioned well below the side rails at, substantially as shown.

The section 1 of the bed is sufficiently smaller in length and height to nest within the section 2 and is combined therewith by inserting the legs 3 at one side of the section 1 between the spring structure 8 and side rail at of the section 2 as shown in Fig. 8, so that the sections are adjustable for extending and collapsing the bed, and are interlocked so as to prevent scpartion thereof when the bed is extended.

The section 1 which remains stationary is preferably provided with knobs 11 instead of casters on the lower ends of the legs 3 so that itwill not move easily. The other section 2 is preferably mounted on bed ends 12 which serve to enhance the appearance of the bed and afford arm rests when the strutcure is collapsed to couch or davenport form. The marginal frame of these bed ends comprises side posts 13 which correspond to the legs 3 of the section 2 and are secured to the latter by bolts 14 or other suitable fastenings and project below said legs so as to support the section 2 at the proper elevation. This construction renders it possible to convert the section 2 into an ordinary cot by merely removing the bed ends 12, or a standard cot structure may be utilized in making the bed by merely attaching the bed ends 12 thereto. The posts 13 are supported by rollers 15 which do not have a caster mounting but are held in a fixed position in line with the required direction of movement of the section 2 or their axes of rotation remain always parallel with the length direction of the bed so that they serve to eifectivly guide the movement of this section and avoid cramping or binding which occurs when the usual caster wheels are employed. These wheels or rollers 15 may be mounted on the posts 13 in any suitable manner, as for example as shown in Figs. 13, 1 1 and 15, wherein the yoke 16 has the wheel or roller 15 journaled on a stem or pin 17 which extends between and connects the arms of the yoke and the intermediate portion of the yoke is inserted into the lower end of the post 13 and secured therein by the rivet 18 or other suitable fastening.

It is not necessary to use any bed ends or arm rests on the section 2 as the latter may,

if desired, have the legs long enough to support the spring structure 8 at the re quired elevation and the rollers 15 mounted directly on the lower ends of the legs 3. Arm rests can be provided on this structure as shown at 19 in Fig. 4: wherein a short frame is secured to the upper ends of the legs 3.

For the purpose of further insuring the necessary direct in and out movement of the section 2, I have provided a pair of guide straps 20 and 21 at each end of the section 2, and between which the legs 3 of the section 1 are confined. These guide straps extend between the side rails 4 of the section 2 and the former may be permanently attached to the side rails. The guide strap 21, however, is preferably pivoted to the upper flange of the inner side rail 4;, as indicated at 22, so that when the outer end is released it may be swung as indicated by the dotted lines 23 to a position directly over the side rail 4, thereby rendering it possible to disconnect or separate the sections 1 and 2 without difliculty when it is desired to use them separately as individual cots. To this end the outer ends of the guide straps 21 are preferably secured to the side rail 4 by bolts 24 or other detachable fastenings, so that these guide straps may be swung out of the way whenever the occasion may require.

A mattress 25 of suitable width to extend over both sections 1 and 2 when the latter are opened out to the full width is provided, and when the bed structure is contracted or collapsed, the portion of the mattress lying over the section 1 is merely folded over on top of the portion of the section 2, as indicated by dotted lines at 26 in Fig. 9. This mattress preferably has a flounceor drape 27 which hangs down along the outer side of the section 2, and there may also be end portions 28 of the flounce or drape preferably separate from the portion 27 so as to fit down between the section 2 and the bed end 12 thereon. WVith this construction it will be observed that the lifting of the mattress in collapsing or extending the bed is not only avoided as it is merely necessary to fold half of the mattress to the position shown by dotted lines at 26, or to the position shown in full lines. but moreover as the flounce or drape extends down around the movable section 2 it is not in anyway disturbed in open ing or closing thebed and there is no possibility that it may become caught in moving parts, as in bed structures of this character which have been provided heretofore.

The bed end 12 at one end of the section 2 may serve as a pillow rest and to provide a pillow rest for the other section 1 a wire ill) frame 29 is pivoted to the top portion 6 of by full lines.

After a bed has been used for some time the spring tension on the spring structure 8 some times becomes relaxed and as the spring structure 8 of the section 1 slides under the spring structure 8of the section 2 in rather close proximity thereto, it is possible that the spring structure of the section 2 might sag sufficiently to catch on the spring structure of the section 1. To avoid contact between the sprin structures and facilitate the sliding relative movement thereof, a pair of straps 30 are extended across under the spring structure 8 of the bed section 2 at suitable intervals and have the outer ends connected to opposite sides of the spring structure 8 so as to serve as guides which slide over theupper surface of the springs 8 on the section 1.

lVith the construction as above described, having the rollers on the movable section arranged to confine the movement of the latter to a direct in and out movement, and also having the guide straps 20 and 21, it is not necessary to grasp the section 2 intermediate of the ends for operating same so as to avoid binding as in previous structures, but the section may be readily operated Without binding by applying the required pressure at the ends of the section or any other point.

In the description of my invention and particularly in the following claims, I use the terms stationary and movable to dis tinguish the sections,-not intending, of course, that the one section is incapable of movement, but to signify that the so-called movable section is the one which is designed and intended to be moved or adjusted in extending or collapsing the bed structure and that the so-called stationary section is de signed and intended to remain stationary while the other section is adjusted.

While I have shown and described my in vention in a preferred form, I am aware that various changes and modifications may be made Without departing from the principles of my invention, the scope of which should be determined by reference to thefollowing claims.
