T0 all fr0/wm t may concern.'

Be it known that I, EDVARD M. S. THOME- SEN, a subject of the King of Norway, residin at Chicago, in the county of Cook and tate of Illinois, have invented certain new and useful Improvements in Folding Metal Beds, of which the following is a specification.

My invention relates to improvements in folding beds, preferably formed of metal, while the same may be formed of any other suitable material.

An important object of the invention is to provide a bed of the above-mentioned character, which is simple in construction, inexpensive to manufacture, convenient in use, and will occupy when folded the minimum space for shipment or exhibition.

Other objects and advantages of the invention will be apparent during the course of the following description.

Figure 1 is a plan view of the bed with parts in section. Fig. 2 is a longitudinal sectional view taken on the line 2 2 of Fig. 1. Fig. 3 is 'a transverse sectional view taken kon the line 3-3 of Fig. 1. Fig. 4 is a similar view taken on line 4 4 of Fig. 1. Fig. 5 is a horizontal section on line 5-5 of Fig. 3. Fig. 6 is a side elevation showing the bed folded and Fig. 7 is a detail side elevation of a foot removed.

My improved bed structure comprises a head member l, and a foot member 2 preferably formed of metal, but any suitable material may be employed. Each head and foot member comprises upstanding preferably tubular standards 2a, connected near and spaced from their lower ends with preferably tubular horizontal bars or elements 2b, as shown. The lower end of each of the tubular standards 2a, is preferably provided with a foot, designated as a whole by the numeral 3. Each foot 3 (see Fig. 7) comprises a preferably tubular body portion 4, to the lower end of which is suitably secured a caster 5', as shown. The upper end of the tubular body portion 4 receives a connecting plug 5, which enters the lower end of the tubular standard 2a, to securely preferably detachably connect the foot thereto, as is obvious. l

The members 1 and 2 are connected by substantially rectangular frames A and B. These frames or frame-sections A and B, are identical, each comprising longitudinal rails or bars 6, which are preferably inverted L- shaped in cross section and connected at their outer ends by transverse horizontal bars 7, also formed inverted L-shaped in cross section. The inner contiguous ends of the longitudinal rails 6 are disposed in end to end relation as shown, and connected by hinge means to be described; the rails 6 of frame B being movable into the rails 6 of the frame A, which may be accomplished by swinging the vertical webs of rails 6 of frame B in to rails 6 of the frame A. This hinge means comprises a connecting member 8, arranged within each of the rails 6 of the frame B, and rigidly secured thereto by means of bolts or rivets 9, having their heads preferably countersunk, as shown. As more clearly shown in Fig. 4, each con-- necting member 8 is preferably inverted U- shaped in cross-section with one end extending into the rail 6 of the frame A. Passing through apertures in the connecting members 8 and in the vertical webs of rails 6 of frame A is a transverse rod 10, the ends of which are flattened to retain the same in place. It is thus seen that a hinged joint is obtained between the inner ends of the frames A and B, whereby such inner ends may be readily swung upwardly but not downwardly below the horizontal position of the rails 6. Arranged within each of the connected members 8 is a spacing sleeve or ring 11 preventing lateral bending of the sides of the connecting member and consequently perceptible lateral movement of one rail 6 with relation to the adjacent rail 6. The intermediate portion of the rod 10 is bent downwardly or depressed, and carries a spacing tube 12, correspondingly depressed or bent, and preferably loosely mounted thereon. The ends of this tube engage the connecting members 8, and together with the spacing sleeves or rings 11, serve to prevent improper relative lateral movement of the rails 6, such as bulging, or contracting laterally. The transverse bars or members 7 of the frames A and B are pivotally lapertured to receive a rod 19. Surrounding the rod'19ris a compressible coil spring 20, serving to urge the bolts 17 outwardly, as shown. y

The numeral 21 designates a bed bottom,

preferably formed of an open metal fabric, attached to the'rails 6 and bars or members 7 by retractive coil springs 22. The springs 22 Vare under suitable tension, when the rails 6 occupy their horizontal position, to retain the intermedial or central portion of the In the use of the bed structure, when it is desired to fold up the same, the bolts 17 are withdrawn from the veyes 14, whereby the inner ends of the frames A and B may be swung upwardly, the rails 6 of the. frame B passing into the rails 6 of the vframe A, as

`more clearly shown inV Fig. 6. The members 1 and 2 then lie flat against the frames yA and B. Vhen thus folded, the bed-bottom 21 is also folded about the tube 12, to be supported thereby, whereby the entire bed structure will occupy theleast space.

1t is obvious that the frames A and B may be readily swung to the horizontal, and

againploclred in such position by meansv of the bolts17 and associated elements.

Itis to be understood that the form of my f invention is to be taken as apreferred embodiment of the same, and that various changes in theshape, size and Yarrangement ofAparts, without departing from the spirit of the same or the kscope of the subjoined claims.

Having described the invention what is claimed, is

1. A bed comprising head and foot members; cross bars hinged to the head and foot members to turn upon their longitudinal axes; lugs secured to the inner sides of the ,head and foot members and arranged in proximity to the cross bars; movable bolts secured to the cross bars and movable into and out of engagement with the lugs; side rails connectedwith the cross bars,r comprising sections which are pivotally connected; and a bed bottom coperating with the cross bars. e

2. A kbed comprising head and foot memfbers', cross bars hingedto the head and foot members, eyes carried bythe head and foot members, Y spring pressed bolts carried by the cross bars and engageable with the eyes, side rails connected with the cross'bars and Vcomprising. sections pivotallyconnected together,:and a bed bottom connected with the cross bars.

3. A bed comprising head and foot members, cross bars hingedly connected with the head and foot members, eyes carried by the head and foot members and adapted to pass through the cross bars, bolts slidably mounted upon the cross bars and having inwardly disposed extremities at their inner ends, springs interposed between lthe extremities of the adjacent bolts and being under ten- Y sion with a tendency to force the bolts away from eachV other and through the said eyes,

side rails connected ywith the cross bars and composed of sections hingedly connected tovgetherand aV spring fabric connected with the side rails and cross bars. Y

4. A bed structure, comprising head and foot members, rails havingV their outer ends permanently pivotally connected with the headA and foot members'A and adapted to swing iny a substantially vertical plane, a bed-bottom, resilient; means connecting' the bed-bottomvwith the head and foot members, and vartransverse member serving to permanently pivotally connect the inner ends of the rails and having itsrintermediate portion depressed to be spaced a substantial distance below the bedsbottom when said bed bottom is vhorizontally arranged ,and to engage the bed-bottom when the rails are swung upwardly in the folding operation of .the bed with allthe parts thereof Y Y.
