PORTABLE BED.

Application ined February 23,1926, Serial m saass; Rnewed January 3, 1828.

My invention relates to folding beds and more particularly pertains to sanitary beds of all metal construction, designedjto be mounted on rollers, and when foldedup, to

bemoved into a closet andkept'out of sight. In constructingbeds of this/type it is 7 important that they be as narrow in side elevation as possible in .orderto economize incloset space and atthe same time be steady and rigid when'moved'out of the closet and utilized. Heretofore it has been found ne cessary. that the head piece of the bed beheavily weighted in order that: it will nottilt or lift upwardly when the bedis lowered, asthe "base space must necessarily be narrow.

It is the object of myrpresent invention to provide a construction which will serve to overcome the above recited disadvantages,

"and at the same time preserve the narrow base span and obviate the necessity of Weighting the bed in any'manner. c A further object is to provide a bed'which will be perfectly counterbalanced at all times while being manipulated intoor out of usable position. I

Still another object is to provide means for preventing the structure from rolling backward or forward while the mattress is being lowered or lifted.

The above and other objectsof my in ventionwill be more fully disclosed in the following specification, and by; referring tothe annexed drawings, in which: v

Figure 1 is a side'elevation of thefbed as it would appear when in a lowered position.

Figure 2 is a rear view of a portion .of the same Figure 3 is a longitudinal section through the head portion of the bed as would appear when the brace legs are let down.

Figure 411s alongitudinalsection through the head portion of the bed as it would'appear when closed and out of use.

Figure 5 is a similar view showing the bed as it "would appear 'when open and ready :for use. i I

In the construction of the bed, opposite sides are identical, they being tied together by suitable spacing bars which will be hereu inafter mentioned, so a description of one side will serve as a description of the other.

Referring tothe drawings, 10 and 11 represent oppositely disposed head leg members, which are U-shaped inform, and preferably made of round tubing,and comprise the horizpntally disposed bars 12 and the depending legs 13 and 14 which are equipped with rollers'15 and 16. The leg members 13 andli are-preventedfrom spreading apart by means of the angle irons 17 "End '18,'the lugs of which are-secured thereto, 1tDheIse constituting the mainframe of the Pivoted to the'angle'irons v17 by means of bolts 19 are the bed rails 20 and 21, which are tied together at their head ends by means of a transverse angle ironfbar 22, goose neck fittings 23 and 24cbeing interposedbetween the bars and the rai'lends.

The foot ends of-the'rails 20'and2l 'are provided with goose neck fittings 25 which are held properly spaced apart by the bars 26 and 27 asshown inFigure 1 of the drawings. I A bed spring 28 is stretched between the two sets of goose neck fittings .to formthe usual platform for the bed mattress,

- (not shown) I The foot'legs of the bed are formed of a U-shaped piece of tubing 29 and are foldably secured tothe bed rails by means of hinge straps 30 and 31.

Leg bars32 'and33'are respectively pivoted to the angle irons 17 and 18 at one of their ends by means of pins'34rand are provided at'their opposite ends with'rollers 35 adapted'to rest upon the floor when the bed is down and-just before the bed is low. ered, and are tied together by the transverse anglebar '36. Pivoted' at 37 to the brace legs, at one of their ends, are'brace bars 38,- which are slotted at their opposite ends,

3 as at 39. Pins 40 project from the angle irons 18 and pass through the slots 39, thus permitting the'brace bars'38'to have a sliding movement. The bars 33 and 38 form a toggle truss for the support ofvthe bed frame when thebed is lowered as clearly shown in Figure 5 of the drawings.

A head board 41, which is preferably formed of tubing bent into theshape of a U, is provided, and the legs of the same are pivotedat 42 to the extension arms 43 sec'ured'to the goose neck members '23 and The ends of the link brace straps 44 are pivoted at 45 to the legs of the head board 41 and their opposite ends have pivoted to them at 46 the link members 47, said link straps 44 being pivoted intermediate of their ends at 48, to standards 49 secured to the fixed angle irons 17 Pivoted at 50 to they brace legs 32 and 33 are link brace straps 51, the opposite ends of which are pivoted on the pins 52 projecting from the link members 47 and also pivoted on the pins 52 intermediate of their ends are the cross bars 53. Interposed between one of the ends of each of the crossbars 53 arid the leg bars 32 and 33 are the springs 54, shown more clearly in Figure 5 of the drawings, the spring is broken out for sake of clearness. Interposed between the opposite ends of the cross bars 53 and the goose neck members 23 and 24 are springs 55, and interposed between theends of the link-members 47 and the goose neck members 23 and 24 are the springs 56.

It will be noticed by reference to Figure 5 of the drawings that the entire bed occupies exceptionally narrow space, and that the bed rails constituting the platform, are locked in a vertical position by means of the transverse angle bar 36 secured to the leg bars 32 and 33, which are also looked in substantially an upright position, the springs 54 acting to pull the brace straps 51 past the pivotal center 34 for this purpose. When the members 32 and 33 arelowered into bracing position the same springs serve to ,press these members downwardly on to the floor when the operator exerts a slight pres-- sure on them to move them past the center 34 in. the opposite direction, as clearly shown in Figures 3 and 4 of the drawings.

As the platform of the bed is lowered, the springs 55 and 56 serve to counterbalance the same, they being so disposed as to increase in tension as the foot end of the platform increases the leverage.

When it is desired to open the bed, first, the members 32 and 33 are lowered to the position shown in Figure 3. During this operation all of the springs assist in cansing them to move downwardly after. they have passed the vertical position.

The bed platform is next swung on its pivots 19 to a horizontal position as shown in Figure 5,

before mentioned. During this operation the springs 55 and 56 exert a straightening out strain on the toggle truss formed by the thereby giving to the frame a wide base supit being counterbalanced throughout this operation by the'springs as During the lowering operation the members.

44 are rocked on the pivots 48 to cause the bed head 41 to assume the position shown in Figure 5. The foot legs 29 are also swung into proper position during the lowering operation, toform a support for the foot end of the platform.'
