Our present inventionrelates generally to collapsible beds, and has purticulnr reference to it construction and mechanism for support mg and guiding themoveinent of such shed as the head thereof, a highly undesirable con-V ditionohtains in thatthe heed o'l the sleeper is insufiiciently exposed to obtain the maxi mum benefit of air und ventilation.

It an object otthc-presentinvention to provide a bed oonstructimi" wherein the bed may be normally positioned entirely Within i1v closet and at the sometime automatically adjustable upon (L11 opening thereof to bring the entire bed out of the closet and into the room. I i

It is an important object to provide such on arrangenientin a manner whereby the single operation oi: drawing the bed outwardly into the room will function autonmtically to withdraw theentirohed in this'munncr, no 7 Briefly, our invent on contemplates the mally positionable: in or substantially verticnl manner Within a suitnhly sized closet, and means for simultaneously (a) sw nging said support outwardly about its'lower end, and (61 causing suid lower end itself tomove hodily out of umclosety i e achieve this gene ral purpose by the provision of two cooperating levers or mem hers, one of which serves as a carrier for the pivot for the lower end of the bed support, and the other of which serves thefnnotion of controlling the movements of the former. In a preferred construction the control lever is pivotnlly mounted to o fixed point upon the floor of the closet and forconvenience sake, this lever Wlll hereinafter he referred to by us as the floor lever. Similarly, thepivot carrier referred to may be in the form of, a lever pivotally supported Within the closet fsido mu of :t-heeloset and upon Wall thereof, in d gSlIIlllflIf 1 this memheriorlever willhe hereinreasons, 7 after termed tl ef wall? lever.

A triangular supportig bracket first positioncd wi'thinthe [closet and m'ay compr e n hii'se13,n rear 14, andnn oblique reinlorc ng embe 15, thisstructnre being suituliily positioned Lin @fix' d, in nor within, the/lower corner of gthecl'oset.

' l e r fined e e ew ji fi mechanism, as illustrated in Fig. 1, is arranged adjacent to the wall 10, these two sets being symmetrical and juxtaposed, and the description of one set being sufficient to disclose the nature of the other.

The forward end of the base 13 is preferably positioned at theextreme forward edge of the closet floor, and this forward end constitutes a pivot point 16 about which a floor lever 17 is designed to swing. The lever 17 may therefore be said to be pivoted at its lower end to a fixed point on the floor of the closet, and it will be observed that the lever 17 extends upwardly in a substantially vertical direction and is provided at its upper end with two spaced rollers 18 arranged in a substantially horizontal plane.

e will point out at this time that a bed support 19, preferably emnprising the usual tubular element forming one longitudinal side support for the bed, is designed to be slidably positioned between the rollers 18. e will also point out that the floor lever 17 is designed to swing from a normal position as shown in F ig. 1 outwardly into an operating position as shown in Fig. 41.

The rear member 14 is of such a length that its upper end will be positioned at a distance from the floor substantially equal to the height which the bed support 19 is designed to assume when in operative position. A point on the member 1 1 is arranged to constitute a pivot point for a wall lever, thispivot point 20 being preferably arranged at the uppermost end of the member 14. The wall lever 21 normally extends from the pivot point 20 obliquely downwardly at an angle of approximately so that its free end lies adjacent to the floor. The lever 21 is ofsuch a length that in its normal position it will be disposed entirely within the closet whereasoutward swingingthereof about the pivot 20 as an axis will serve to bring the free end ontirely out of the closet. In the construction shown, the various parts areso designed that the lever 21 is of a length greater than the depth of the closet, and the dot and dash line 22 indicates the general path of the free end of this lever. i

The rear or lower end of the bed support 19 is pivotally associated, as at 23, to the free end of the lever 21. This may be accomplished by providing an integralstructtn'el 2 1 which includes a socket for the reception of the end of the support 19. It will be noted that the latter is preferably arranged along a gradual double curve adjacent to its rear end so that it may position itself within the socket and at the same time pass between the rollers 18.

Our invent-ion contemplates that a pull will be exerted uponv the support 19 tending to draw it outwardly in a swinging direction about the point 23 as an axis. It will be observed that when this 1s done, the engagement of the support 19 with the rollers 18 will cause the floor lever 17 to swing outwardly in a manner indicated by the dot and dash line 25. So that this outward swinging of the floor lever 17 may at the same time control the movement of the wall lever 21, a link 26 is provided extciuiing between the free end of the lever 17 and a medial point 27 of the lever 21. In this way, an outward pull upon the support 19 will cause the latter to pivot about the point 23, while the point will at the same time be made to move bodily out of the closet along the path 22.

These movements of the elements 17, 19, 2G, and 21 are more clearly shown in Figs. 3 and i, and it will be noted that in the ultimate position, wherein the bed is ready for occupancy, the support 19 is substantially horizontal and in substantial alignment with both the link 26 and the lever 21. These GlGlllClli'S are retained in this position by the weight of the bed itself, it being understood that the end portion of the support 19 shown in the drawings is but a relatively small portion of the entire length thereof.

In 2, which is a view taken from the right of Fig. 1 and looking at the mechanism adjacent to the wall 10, one method of constructing and arranging the elements de scribed has been shown. It will be noted that the lower end of the floor lever 17 is forked to provide two spaced bearing points 28 and 29, these portions being rotatably mounted upon a spindle or shaft 30 provided in the forward end of the member 13.

It will also be noted that the wall lever 21 is not directly behind the lever 17, and that the structure 24. therefore comprises an angular portion 31 the lower end of which is arranged to provide a bearing 32 and the upper port-ion of which is arranged to provide the socket hereinbefore referred to for receiving the end of the support 19. The bearing 32 is mounted upon a pin carried by the lower end of the lever 21, thereby constituting the pivot point 23 shown in Fig. 1.

It will also be noted that the link 26 is p referably provided with a forked upper end which provides two bearing portionsfii and 34:, the latter being mounted upon a spindle or shaft 35 extending completely across the closet.

So that the manipulation of the bed will be one of substantial balance. a set of springs 86 is provided extending between the lower end of the lever 17 and a lined point upon the structure 241. The latter fixed point is pre erably provided in the form of a transverse beam 37 extending transversely across the closet and between the portions 2 1. Before explaining the functions andoperations of the springs 36, we will point out that the support 19 will slide out "ardly"between the rollers 18 during its out-ward swing. in

other words. whereas a certain portion of the lower end oi the support it) is disposed hotwecn the pivot 23 and the rollers 18 when the support 19 is in its normal position m shown in Fig. 1, u much smaller portion ot the element 19 lies lgietwecn these q iointsntter the bed husbeen opened. This d-ue to tl tin-t thnt the pivot point '12?) hos changed. position. relative to the pivot point 16, and consequently the support 19 will have moved tli.ti'\\'21ttll}' in a slidnhle manner during the opening of the bed. lneidentell v. this out- Nzli'tl sliding of the support 19 will bring the rollers 18 adjacent to the end ot' the socket utter the bed has heen'opened, this disposition of the elements being clearly shown in Fig. 1. i

When the eleincntsere in their normal rel-- lnpsed positions as shown in Fi l. the support 19 is in substantially vertlezil tion its Weight being supported 'iupon on adjustable block 38 provided on the portion 13. hen the support 19 is pulled out werdly, its'center of gravity will shift to the right, end the rollers 18 will ossun'iethe :tunetions of fuller-unis. In the absence oft the springs 36. thesupport 19 would tend to fall outwardly, swingingnlmntthese tulcrnn'is, because of the ever increasing lever erni between these fnleruins and the center of gravity. By providing the springs 36,. this tendency to fell outwardly is counternoted, and the springs are so ermmgjetl, looth as to strength and disposition,that the sup port 19 will he in substantial hnlnnce during nil portions of its movement.
