To all whom it may concern:

Be it known that I, GEORGES MIssoGENrs, a subject of the King of Greece, residing at Edgewater, county of Bergen, State of New Jersey, have made a certain new and useful Invention in Foldable Cots, of which the following is a specification.

This invention relates to foldable cots or beds.

The obj ect of the invention is to provide a cot or bed structure which is simple, economical to manufacture, efiicient in operation, and which is capable of being folded into a light compact package of small dimensions and small weight or distended into position to form a cot or bed. 2

A further object of the invention is to provide a foldable cot of the nature referred to which is strongand durable, and which affords comfortable resiliency when in use.

A further object of the invention is to pro vide a foldable cot of the naturereferred to with a convenient head rest.

Other objects of the invention will appearmore fully hereinafter.

The invention consists substantially in the construction, combination, location and relative arrangement of parts, all as will be more fully hereinafter set forth, as shown in the "accompanying. drawing, and finally pointed out in the appended claim.

In the drawings Figure 1 is a view in side elevation of the frame for a foldable cot or bed constructed in accordance with and embodying the principles of my invention, and showing the frame in distended position for use.

Fig. 2 is a top plan'view of the construction shown 1n Fig. 1; 1

Fig. 3 1s a view 1n vertical transverse sec- I tion on the line 3, 3, F ig. 1, looking inthe direction of the arrows.

Flg. 4 1s a broken detail view in section of r the construction at the foot of asupporting leg.

Fig. 5 is a broken detail view showing the v ,foldable' connections of the brace rods em- :Fig. 6- is 'a broken detail view in top plan,

partsin horizontal section, showing the side tensioning members. I

Fig. 7 is a broken detall'vlew on the line 7, 7, Fig, 1, looking in the direction of the" arrows, and showing the swivel plate conpection ofthe legs and top or mattress supporting arms to the main body member of the frame. I

Fig. 8 is a broken detail view in section on the line 8, 8, Fig. 7, looking in the direction of the arrows. r

Fig. 9 is a broken detail view in elevation 1 The main body portion of the cot frame swivel conconsists' of the member 12-, 13,-preferably formed of metaland of channel formation,

as clearly shown in Figs. 3, 7and 8. These main body members are hinged together at their abutting ends upon the hinge pivot 14: so as to fold upon each other when the frame isto be folded up or distended into line with each other for use as acot or bed as shown in Figs. 1 and .2. Suitably hinged upon the pivot bolt 14 of the main body members 12, 13, and depending therefrom when the frame is distended for use, but foldable against the body members when the frame is folded up, is a bracket 15, to the lower end of which is connected a brace plate 16 to which are anchored the brace rods 17 18. Also suitably pivoted upon the body members 12,13, at their hinge axis upon a pivot bolt 19 is a plate 20, to cars on which are pivotally connected as at 21 brace arms 22 which extend transversely across the frame when distended for use to brace the side members 23 of the mattress support. It willbe observedthat thebrace plate 20 extends transversely across the main body members 12, 13'. The brace plate 16, however,extends in'thedirection of the extended length of the body members, and

at the opposite edges thereof is provided with hook portions 24 over which the leg braces 18' engage, flaIIClH-Wlth eyeletsfinto which the braces 17-engageg At the remote ends of the body members12, 13, are pivotally secured swivel members 25', which project outwardlyor away from the-endsof the body members 12, 13, and each of which pmvided with ears26 forming sockets condition ofthe frame. In practice the, dis ;tention between the free ends of the corresponding= legs= 27 atoppositeends of the 6bwithin which are pivoted the ends ofleg members27 and top supporting arms 28 in equally spaced relation to each other. The leg members27 when the frame is distended for use extend outwardly and downwardly away from each other to constitute sup porting leg for the cot. In practice I prefer to form the leg and arm members 27 28, of metal tubes to reduce weight and to the free ends of the leg members 27 are suitably secured caps 29 to afford means for attachment thereto of the brace members or rods. A 'simplemethodof attaching the caps 29 to the free ends of thelegs is shown in Fig. 4 wherein the free ends of-the tu-' bular legs are rounded over as indicated at 30 to form a retaining shoulder for an interior washer 31. or over the free end of the tubular leg 27 and is riveted as at 32 to the interior washer 31. When the frame is in distended position for use'the caps 29 at the free ends of the legs 27 at the same end of the frame are connected together by brace rods 33.

Said caps are also connected through'brace rods 34 to the free ends of the top supporting arms 28. referred to which are connected at one end to the brace plate 16 as above described are s also connected at their opposite ends tothe caps 29. In practice I prefer to'makethe various braces 17, 18, 33rand 34 in pivotally connected sections so as to permit'them to be readily and easily folded together. In

' the case of the leg braces 18a single member is connected to the hook portion 24; of

the'brace plate 16 while independent portions connect the opposite end of said single portion respectively to the caps 29 of the two opposite legs 27 at the same end of the same, as most clearly shown in' Figs. 2 and 3. A simple form of hinge connectionbetween the portions of the various braces is shown wherein in thecajse of the leg braces 18, for example, seeFig. 5, the single portion which is connectcd to the brace plate 16 has the end thereof bent or doubled back upon itself'to form 'an eyelet 35, and held in place by means of a clip or sleeve 36, the extremity 37 of said end portion. being bent over the end ofthe sleeve 36. Through the eye 35 is passed similar eyes, similarly formed in the ends of the otheriportions 0f the braces 18. In like manner theportions of the brace or'tie rods 34 are connected together. See particularly Figs. 1,

2 and 3. This affords an exceedingly sinr -ple form of connection which issufiiciently rigid when the parts are distended *foruse but which permits the parts ofthe ties or braces to be folded togetherin the collapsed main framegis somewhat greater than the A cap '29 is applied to" The leg braces 18 above combined lengths of the main body mem-' bers 12, 13, thereby securingstability in the 1 while at their opposite ends is pivotally connected a clamp member 41. ,.Tliis clamp member is provided with a curved arm 42,

see Fig.10; which engages through a link 43 and is retained in engaging relation by a ring 44 carried by the side wire or member 23. By simply slip-ping the ring 44 toward the left from'the position shown in Figs. 1

and 10, the arm 42 is released and may be readily withdrawn from the loop or link 43 thereby detaching the mattress side supporting member 23. The linlc43is engaged into aplate 45 which is secured to the ex- ;tremity or free end of the "top supporting arm28. The plate 45 may be secured to' the tubular end of the arm 28 in identically the same manner in which the'c'ap 29 is secured to the freeiend of the. leg 27 'as shown in Fig. 4. The plates 45' at opposite sides of the frame are connected together by a tie rod 46, see right hand end of Fig. 2, which 'tierodis made in sections swivelly connected together by engag'ingeyes 35 "exactly as above described with reference to the sectional leg ties 18. The vertical tie rods 34 are also 1 connected intopthe plates' 45. As:

in the caseof the legs 27 the :distance between the free ends of' arms 28 on thesame side of the bed or. other frame are a greater distance apart than the combined distended lengths ofthe main body frame members 12, 13, and, hencethe tie rods 34 and 46 and the side members 23" of the :mattress support formpin effect trusses to take' the strains while securing a desirable degree of flexibility and comf'ort when the bed is in use and atxthe same, time permitting parts to be detached and folded together into compact are connected tothe caps 29 at the fI'QGBIldS "of the leg members at thatend of the'frame through thetie rods.34,' and the plates 40 at opposite sides of the frame are connected or braced together by the tie rods 47 which in like manner @to lthetie rods 34am made in sections pivotally" connected together 1' through engaging eyelets 35- as "above ex- 'plained; I vAtthe headend of the frame I provide a foldable head rest of extremely simple "eonrelation. "In like 'manner to the plates 45 the :plates 40-at the opposite end of the frame struction consisting of vertical tubular supports 48, see Figs. 1, 3 and 11. These supports are pivotally connected to clips 49 carried by horizontally disposed head rest side members 50. At their extreme outer ends the horizontal members 50 are connected together by a cross member 51 which is hinged as at 52 to one of the horizontal side members 50 and detachably engaged by means of a hook end 53 in the outer end of the opposite horizontal side member 50, see Fig. 2. The opposite ends of the horizontal members 50 are detachably connected by short rods 54 to the vertical tubular sup ports 48. The lower ends of the Vertical supports 48 are provided with longitudinally extending slots 55 through which pass the vertical tie rods 34. This structure'af fords a very simple and eflicient and at the same time a foldable or collapsible and resilient comfortable head rest for the cot or bed when in distended position for use.

It is desirable to apply a suitable yielding transverse tension to the side members '23 of the mattress support, and for this purpose the transversely extending brace arms 22 are employed. To the outer or free ends of these brace arms 22 are pivotally connected vertically disposed members 56 having outwardly presenting hook portions 57 at their upper ends which engage the side members 23 of the mattress support. To the lower ends of the hook members 56 are pivotally connected transversely extending rods 57, the inner ends of which carry suitable plates 58, see Fig. 6. A tension spring 59 is interposed between the stop plate 58 and a relatively fixed plate 60 carried by' the ends of a link 61 which is connected to the associated brace arm 22 adjacent to the point of pivotal connection with the plate 20. The stop plate 58 slides freely along the legs of the link 61 and the spring 59 pressing thereagainst exerts its tension upon the said stop plate 58 and arm 57 and hook member 56 in a direction to rock the hook end 57 outwardly thus imposing a desirable yielding. tension upon the side members 23 of the mattress support.

It is to be understood that a strong canvas, not shown, is applied over the head rest and over the side members 23, said canvas to be applied along its side edges to the side members 23, and at its ends over the tie rods 46,

47, which in addition to their tie rod function constitute the transverse end wires of the mattress support.

A cot or bed frame constructed as above describedis exceedingly simple, can be compactly folded into a space a little more than a foot and a half long, a little more than a half a foot wide, and a little more than a quarter of a foot high, with a total weight of approximately ten pounds, thereby rendering the same exceedingly desirable and useful not only as a foldable cot or bed easily transportable, but which is strong and durable and which can be quickly distended for use or folded for transportation, and

are not only strong and durable but capable;

of being easily manufactured and quickly assembled, and the completed article capable of being quickly and easily folded for transportation or distended for use.

Having now set forth the objects and nature of my invention, and a construction embodying the principles thereof, what I claim as new and useful and of my own invention, and desire to secure by Letters Patcut, is

In a foldable cot or bed structure, a foldable head rest frame including vertically disposed arms, and means for supporting the same, horizontally disposed members pivotally connected to said vertical arms, rods detachably connecting one end of said horizontal members to said vertical arms, and a rod pivotally connected to the free end of one of said members and having detachable connection with the free end of the other of said members.

In testimony whereof I have hereunto set my hand on this 30th day of July, A. I).

GEORGES MISSOGENIS.
