Application fi1ed February 26,1`023..` Serial' No. 621,451.`

My iinventionf relatesV to foldable beds' `'which are adapted to be concealed in a suitable closet or compartment whennot in use.

It is lan robject of the inventioiirtoprovide a bed of this characterV having a very narrow., carriage and anextensiblev means mounted upon the carriage for preventing the bed from overturning when beinglowered from the raised position into, horizontal posi-tion.

The especial/advantages and further ob` Vjects will be made evident hereinafter.

Referring tothe drawings which are for illustrative purposes only, Fig.. 1 is a side elevational View of avcloset bed incorporating thc features of my in* vention. f

Fig. 2 is a. view taken as indicated by the line 2,-2 of Fig. 1. j f s Fig. 3 is an enlarged fragmentary 'View illustrating the mechanismv of they extensiblebalancing member, in which vi-ew the member is shown in raised position. s Fig. 4 is an enlarged fragmentary section showing a form of retaining member I have devised. ,s 1

Fig. 5 is a fragmentary view similar to Fig. 4 showing the manner in which the re-l taining member rotates inwardly whenthe sp'ringstructure is deflected downwardly.

Fig. 6 is a diagrammatic plan view of an alternative form of spring structure which vmay be employedl with the bed.

Fig. 7 is an enlarged fragmentary plan view of one corner of the spring structure shown Vin Fig. 6, illustrating the manner in which the retaining' edge is `formed continuously around the edge of the spring.

. Fig. `8 is an enlarged fragmentary section taken'` upon applanerepresented by the line v.8e-8 of Fig. 7.k Y v 'l 1 p The bed'structure shown in Figs. 1 to 3 of the drawing comprises a. carriage 411 provided with castors 12 which are inserted in the vends of the legs 13 yof end frames 14; A pair o'fthes'e' end frames is provided, each of which is provided with a lowei cross bar 16 land an upper cross bar 17. An intercon-v pair of posts 22. These posts are situated Vertically f from the interconnecting bar 18 are extended ay adjacent'to Vthe ends of. ther-member 61:8, if

rbetweenithe upper ends of the posts22 and ,the upper crossbar 17 pivot-'bolts 24 are extended upon which boltsk the sidebars 25 of the spring supporting structurer 26 are .piv-

shown inV dotted lines in'thatfigure.A y At the foot of the spring structure 26 a *,oted, thusenabling the spring structure 26":t 1

rto swung between ther raised position shown in full lines land the loweredposition i foldable foot frame 27 is secured whichmay be-swung into vertical position 'as sh'ownvat i 28 when lthe springY structure isv lowered.

V-Upwardly from the brackets 30 situated yat fthehead'of the spring structure 26 there extend posts 31 towhich ahead board 32 is*- pivoted at 33. This headboard/is.linked to the carriage structure bylinks 35 which are turnably secured upon brackets 37 mounted upon the uppe1vcros'sbarsf17. In

this manner al parallel link arrangement is provided whereby the head board 32Vis main-k tained in asubstantiallyperpendicular posii tionpat' all times, with tlieresult that when the .spring structure is swung ilntothe raised position, the head board 32 extends substantially perpendicular thereto and serves asa yineans for clamping'thc lbed clothesfand pillows firmly in placewhile thefspring frame is thus raised. w

Inorder tol counter-balance the weight of `the spring structure, tension springs 40 are employed which areiatta'ched to the extreme rearwardend of the .spring supporting strucjt'ure and impart a rotative force .thereto v which assists ini'swinging the-lower end of the spring structure upwardly.` It. will readilyA be perceived that such springs also -resistthe lowering ofthe spring structure from the vertical position andr'itfis for this reason thatl the carriages of closetjbedshavef-l Y been made of considerable width to prevent their overturning when the loweringv of the bed is attempted. 1 .l

My invention lprovides a meanswhereby a very narrow carriage may/be employed, and j further provides means 'for stabilizing :the

structure while the .spring member isbeing lowered, thus preventing the bed fromv 'top- -pling over upon the person attempting rto lower it. Forl this purpose- I' employ an extensiblemember 41, whichis formed from f a light structural angle,A and is employed with the legs 42 thereofinwardly directed.l

At thev outer extremity of this;l U-shaped'- member 41 short legs 43 are secured which Y. tracteclY position shownV in Fig. 8.

support` castors' 44.*Theinner ends of the legs 42am' pivoted upon rivets `45@ located adajcent to the' forward ends 4of the upper cross 'bar 17, thus making. it .possible to .savingy the extensible member'41 from the position' in whichfit is shown inl.i1 ig. Ito-there- The springs which act as al counter-balance vfor "the spring structure 26 are attached to brackets 47 which are swingably mounted uponv rivets 48 positioned upon the impor` crossbars 17 between the bolts 24 upon which the springstructl''nel is pivoted and the rivets aboutr which the member 41fis swingable.

A tension spring 49 extends fromthe lower end of eachbracket 4:7, in a' direction oppositev to that of the spring 40, and connects-- Vto the *member` 41 at 50.: These springs 49 servev to hold the" extensible member'41 either "in the retracted position shown in Fig; 3 or the extended: position shown in Figs. 1 and 2. It will bese'en'th'a't astthe member 41V is swung outwardly as indicated bythe arrow 52, the points 50 at which the' springsh49 attach thereto wild describe ar'c' aroimd'` the pivot 45and thespr'ings upon passing' the pivot pointwiil exert their tension in a plane belowthe pivot point, as indicated by the dotted line 53,. thus applying a force which will. hold the extensible member; 41 securely `down and will resist its raised by hand, or relatively' raised/.due to they tendency for the bed to over-#balance as the spring supporting structure 26 is lowered.;4

For the purpose oflilnitino the downward Vswing of the extensible member' 41, a link 55 'is pivoted at 56 to the inner' face of each leg 42'. In the lower end oi each link 55 aslot 58 is formed which rides over a pin 59 mounted in a leg 13 of the carriage frame 14.

In Fig.r 3 the slot 58 is shown raised upon the pin 59until the upper end thereof comes to rest against the pin, thus vpreventing further downward travel of the linlil with lthe result that a limitto the-downward swing of the member 41 is provided. The link 55 is `soproportioned.that the memberl 41 will be brought to rest in a position in which the c'a'sto'r's l11i-*Will just rest upon the Hoor vas insieme Fig 1.- f

' 'A rivet 60 is placed each side' rail 25 loi thev spring structure 26' at a" point just above that at which the cross portion'l of the.` member 41 strikes .the side vrails; as shown at 62 in Fig. 3. In this manner means are provided. for preventing. thelowering Aof the bed structure when the extensible member is in raised position. In order to lower thesprinfg' supporting structure 26,

the eXtensible Ymeniber must iir'st be lowered Vinto the position shown in Fig.' 3. l
