COLLAPSIBLE BED.

Specification of Letters Patent. Application filed August 27, 1910.

Patented Mar. 18,1913. Serial No. 579,314.

Bc it known thaty l, LnoroLD BIR, a sub- Austria-Hungary,

and a resident ot' Vienna. 1n the Empire ot .\ustria-liungarv. have invented new and n v x n useful lniprovements in (Jollapslble Beds,

of which the following is a specification.

in which the My invention relates to a collapsible bed in which, inY its collapsed condition, the mattress frame does not posts. 'lhis result is attained owing to the fact that the -connecting members to which the parts of the mattress frame are pivoted move downwardly along the bed-posts when the bedstead the collapsible cross connections between the members of the mattress frame serve for stretching the mattress.

In accordance with the present invention the mattress is foldable and preferably folds up automatically when the bedstead is collapsed. ln the construction illustrated the mattress, like the collapsible parts of the mattress frame, are formed of two independent parts each of which consists of a number of longitudinal which can be collapsed, accordion fashion, by spring action.

An embodiment of the invention is illustrated in the which-A Figure 1 is a side elevation. Fig. 2 is a front elevation, and Fig. 8 shows the bedstead collapsed. lThe positions shown in broken lines in Figs. 1 and 2 show the intermediate positions assumed by the several parts.during collapsing. Fig. 4 shows the sleeve serving for connecting the horizontal bars of the bedstead. Fig. 5 shows the hinge provided in the middle of the horizontal longitudinal bars viewed from the middle of the bed. Fig. 6 is a side elevation of a bedstead posts and the mattress frame membersconsist of angle iron. Fig. 7 is a cross section, on a larger scale, on the line A-A in Fig. 6. Fig. 8 shows the bed in plan with the transverse stays l2, 13, removed; the mattress is here shown on the left hand side with wire meshes, while on the right hand side only the longitudinal wires are visible. Figs. 9 and l0 show Separate links of the mattress to a larger scale.

igs. l1 and 12 show the collapsed bed in side elevation and in plan respectively, and

project, beyond the bed I is collapsed. In this bedstead panels or divisions accompanying .drawing in- Figs. 13 and 14. show the manner in which the mattress is folded.

The pillars .l and 2, arranged in pairsatf the head and foot of the bed, are connected by horizontal bars on which the mattress or the like is secured. Each of these bars "of the mattress frame, two of which run longitudinally of the bed and two transversely thereof, consist of two parts 3, et and 5, 6 respectively; the outer ends of each part 3 and 5 and 4 and 6 being pivoted to sleeves 7 slidable on pillars l and 2 while the adjacent ends of the parts 3, 4 and 5, 6, are hinged together. This renders it possible to bring the horizontal bars in a parallel position to the pillars of the bed, the sleeves 7 traveling downwardly and the hinges 8 and S), provided at the middle moving upwardly, so that in the collapsed position'the members of the mattress frame do not project beyond the pillars.

To provide for guidance and stiifening of the parts, the longitudinal members are connected by coupling rods 10, 11 with the pillars. and the pair of pillars at the head, and at. the foot of the bed, are connected by transverse stays 12,13, the lower ends of which are also pivoted to the sleeves 7. As a result of this construction, the vloedstead can be folded both longitudinally and transversely. Finally, in the position in which the bed is ready for use the sleeves 7 can be retained by means of hooks 14 or the like mounted on the pillars.

The longitudinal bars are supported at the middle by feet 15 stitfened by means of cross bars 16 and pivoted to the hinge 8 (Fig. 5). AThe transverse bars 16 and in particular the hinged parts 5, 6 serve for stretching the mattress transversely as when opened out they extend the mattress along its width. `When opened parts 5, l6 are secured automatically but they can also be secured from collapsing by means of some suitable device, such for example as a clamp 17, adapted to be slid over the hinge 9 (Figs. 6 land 8).

The bedstead may consist of tubes (Figs. l to 5) or parts may consist of angle iron.

and 8 for example the pil- Thus in Figs. 6

lars l', 2 may be formed of T iron the cross stays 5 of angle iron and the parts 6 of T iron. In such a case the displaceable .connecting members 7 are' formed t0
