FOLDING COT.

To all whom it may concern:

Be it known that I, Jos-nrii LUPrINo, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New. York, have invented certain new and useful Improvements in Folding Cots, of :which the following is a specification.

' .This invention relates to folding cot-beds and particularly to cot-bed of this type which may be readily and easily folded into atcompact structure so as to occupy a minimunrof space and to .facilitate the portage andtransportation of the same, and which use, easily manipulated, and comfortable to 'ing the ei nlsections inwardly to a position above and parallel to the main sectiomthe main section having a length at least as great as the combined length of the two end or: outersections, the latterin folded position-being located in non-overlapping relation thereby providing an inoreasedlengthwise housing space and at the same time a compact structure.

- Other objects of the invention will appear during the course of the ensuing description, reference being had to the accompanying drawing forming a part of thespecification wherein like reference characters indicate similar parts'throughout the several views and wherein Fig.1 is a perspective view of my. improved cot-bed in an open or unfolded position; Fig. 2 is a side view thereof in its folded position; Figs. 3 and 4 are detail views indicating successive stepsin theoperation-of the parts and Fig. 5 is a detail view indicatingfthemanner of operation of the outer sections.

In-the preferred fornrherein shown and described my improved folding "cot comprises a main or relatively stationary mattress section 10, and a pair of inter-connected swinging sections 11 and 12 pivoted or hinged thereto at each end. Each con- Application filed January 17, 1921. Serial No. 437,748.

each end of the bed.

Specification of Letters Patent. Patented Feb. 28, 1922.

necting mattress section 11 is pivoted, or hinged intermediate its length as at 13 to the main mattress section. 10. One end 14of each section 11 is pivoted or hinged to an outer or end section 12 and at its opposite end has connected thereto a pair of folding legs 15. In the present instance in order to provide space for the legs 15 between the sections 10 and 11, the latter preferably comprises a pair of members or side bars 30 and 31 suitably secured together. The member 31 has an offset-portion 32 and is pivotally connected to the leg 15 as .at 17. The folding legs 15 are preferably pivoted as at 1.5 to depending brackets'16 rigidly secured to the siderails of the main mattress section 10. Suitable lost motion slots 18 are provided in each leg 15-f0r the movement of the pivot 17 thereby ensuring the necessary flexibility during-the operation of the various parts. i

In order to provide suitable supporting i means for the outer or end folding sections 12 each section thereofis provided with. a pair of foldable legs 19 pivoted as at 19 to the side rails of section 12 and adapted, upon swinging said sections to their folded position above the main section '10, ,to loe moved to a position substantially parallel vith.the section 1.0. This operation; as i will be observed ;is controlled by means ofalink 2O pivoted to the upper end 20"of each movable leg 19 andalso pivoted to each intermediate section 11; In order tostrengthen the structure and maintain the legs 19in parallel relation, I provide suitable tie bars or braces 25 connecting the adjacent legs19 at It will beseen that I have provideda very simple but ellicient cot-bed whichmay be readily manipulated and converted from. an 1 open or unfolded position into a compact structure occupying a minimum of space as illustrated in Fig. 2. Inoperation in order to fold or collapse my improved bed or cot from the position illustrated in Fig. 1 it is merely necessary-to grasp the outer section I 12'and swing the same upwardly and inwardly to a position above and substantially parallel to the main section 1O. During this operation due to the fact that each intermediate section 11 is pivoted to the main section 10, this section upon being swung about the axis 13 will act as a leverto swing the legs 15 in an opposite direction .and to a position substantially parallel with the side tal and endwise alinement with each other thereby providing sufi icient housing space for the mattress without causing the ends of the latter to be overlapped one above the other. v Furthermore due to the fact that each leg 15 is pivoted adjacent to one end'thereof as at 15 to the bracket 16, and' due to the fact that the side rails of the section 11 are pivoted as at 17 to the legs 15, the sections 11 therefore when swung from a horizontal position to a vertical position as illustrated inFig s. 5, 4 and 3, due to the inter-connections will swing the legs 15 from a'verti cal position to a horizontal position, the one having a swinging movement in a direction I opposite to the swinging movement of the other. The legs 15 have each a fulcrum in termediate its length at 15 upon thernain section-10, and are operated by the interniediate section 11 by virtueof thedirect connection at oneend' 17 with the free ends of the intermediatebed section. Also it will be observed that the supporting legs 19 and 15 are automatically controlled and oper- 'atedthrou'gh'the medium of the sections 11 andiipon folding the bed from the position of Fig. 1 150 the position of Fig. 2 the supporting legs 19 and 15 will be swung from a vertical position to a horizontal position toward each other. Each of the supportlegsle are provided with suitable casters 27 whereby in its folded position the bed is adapted to rest thereupon and may be easily shifted or moved from 'placeto place. In the present instance the several sections of tliefra'rnework are all connected by a single "stuffed mattress support herein shown as a spring or spring mattress 40 which may be connected at its ends to the framework by suitable coiled springs 41.

When it is desiredto unfold my improved cotbed from the position illustrated in Fig. 2, it is merely necessary to grasp each outer section 12 and swingthe same through the successive positions illustrated in the Figs. 3 and 4-to the position shown in Fig. 5 wherein the section 12 is in an upright position at right angles to the section 11 which has assumed a horizontal position in the operation. From an inspection of Fig; 5 it will be observed that the foldablelegs 19 are not opened or moved during thisope'ration so that the operation is not hampered by the 'tion of the parts. served that the distance between the pivots swinging thereof, but that the legs 15 alone are swung to their supporting position and thus "support the weight of the bed, making itmuoh easier to manipulate the other parts,

wvhereas if it were attempted to first open the sections 12 and consequently ,both'pair of legs at the same time the operator would have to supportthe entire weight of the bed oif the floor, which would be a very diflicult thing to do. Hence owing to the particular location of the several pivots betwe'enlthe legs 19, links 20, and bed section 12 the legs 19 are locked in position at this time and it is practically impossible to open orunfold the same by an attempt to do this by moving the bed section 12 until the legs have been grasped and swung outwardly (as illi1s-' trated in dotted lines in Fig.5) thereby swinging the pivots 19 and bed section 12 outwardly and downwardly which thus permits the section 12 to be readily swung to a horizontal position and the legs 19 swung to their supporting position.

i In other words itwill be seen with reference to F ig; 2 and Fig. 5 in full lines; that normally the legs 19 in closed position are substantially in alinement with the section 12, and hence theseveral pivots 20", 19; and

14, are in such approximate 'alinement as to form substantially a dead .center. v Thus when attempting to swing the sections 12 downwardly from the full line position of Fig. 5, the links 20, by virtue of this relation of pivots, act as a locking means and hence,

at this time, the section 12 together with the legs 19 are immovable. Thereforeinorder to accomplish the unfolding of the legs 19 and sections 12, it is necessary to shift the pivots 19 with relation to the pivots 20 and 14 in order to permit the links2O tobe actuated and to unfold the legs.19. This is acoutvvardly a small distance as shown in complished merely by swinging thelegs 19 dotted lines in Fig. 5, and thereupon by grasping the ends of section 12, the same together with the legs" 19 -=can be readily swung-to the position in Fig; 1.

My cot-bed is opened inthe manner above described whereby the legs 15 arefirst swung to a position to support the entire bed, and thereupon the legs 19 are unfolded to support the sections 12 sothat the user does not have to contend during the openmg of the bed with two sets of swinging legs while supportingthe entire weight-of the mattress; During the operation of the legs 15 by the intermediate sections 11 each pivot 17 slides freely in its slot 18,-the

latter being important for flexible;opera- Itwill be further 6b- 13 and 17 of the section 11 is substantially the same as the distance between the pivot 15 and the outer end of the slot 18, o'rfbe tween the pivot 15" and the normal posi tion ot'the pivot 17 in the slot 18. Hence the essential purpose of the bracket 16 is-to space the pivot 15" from the central longitudinal'aXis of the section 10 by a distance substantially equal to the distance between automatically foldable' legs for the bed adapted to; be operated upon a predetermined movement of certain of said sections, and means for automatically restricting the movement of certain of said legs, whereby the others may be operated prior thereto.
