FOLDING BED.

Application filed November 15, 1927. Ser'ialfNo. 233,468.

It is the object of this invention to provide a bed so constructed. that when it is swung upwardly, the beddingwillbe gripped and held against slidingdownwardly, lengthwise of the bed. Another object of the invention a is to provide novel means whereby the legs,-

of the bed will be folded, when the bed is swung upwardlyand when the bedding is gripped. I i i A further object of the invention is to provide novel means whereby the legs will, be swung downwardly and the bedding released, automatically, as the bed is swung downwardly to a horizontal position.

It is within the provinceofthe disclosure to in'iprove generally and to enhance the:

utility of devices ofthat .typeto Which thev invention appertains. r J

lVith the above and other objects in view which will-appear as the descriptionprocoeds, the invention resides in the combination and arrangement of parts and in the (mails of construction hereinafter described and claimed, being understood that changes in the precise embodiment of the invention herein disclosed, may be madewithin the scope of what is claimed without.

departing from the spirit of the invention.

In the accompanying drawings Figure l shows in side elevation, a device constructed in accordance with the invention, the bed being lowered;

Figure 2 is a similar View wherein the bed appears partly raised;

Figure 3 is an elevation wherein the bed has been completely raised, parts being broken away, 1

Figure 1 is a top plan; V

Figure 5 is a fragmental perspective showing one end of the bed.

The device forming the subject matter of this application con'iprises a main frame 1 which is pivotally mounted intermediate its ends, and nearer to one end than the other, as shown at 2, upon inverted U-shaped supports 3, having upstanding lugs 41. An auxiliary frame 5 is located above the main frame 1 and is provided with any suitable means 6 for supporting the bedding 7.

A loop-shaped end member or bedding grip S is pivoted at 9 to the auxiliary frame 5 and is pivoted at 10 to the main frame 1, the pivotelements 9 and 10 being spaced apart longitudinally of the bed, and verti- "ally as well, as Figure 1 clearly shows.

Legs 11 are PIOVidBC, iii-the embodiment disclosed, although the legs may be omitted if desired, and any suitable support ng structure supplied in-their place. The legs llare pivoted at 12 to the sides otthe auxiliary name 5, a, re p voted at let to the sides of the main 'frame'-1,-;the P117013 elements 1 1 and 12 being spaced apart both vertically and lengthwise of the bed. A fixed' head section 15 secured to one end of the auxiliary frame 5.

:Levers 16a e suppliecl,-and are pivoted at 17 to the :auxihary frame 5 and at 18 to the main frame 1. The' pivot elements 17 and 18 are spaced apartlongitudinallyof I the, bed, as well as vertically. Thelevers are located'at that end of the bed which is remote from the loop-shaped end member 8. The levers 16 have studs 19 which slide in slotsQO formed in radius arms 21,-the

upper ends of the radius-armsbeing pivoted to the frames 1 and 5. The operator swings the bed upwardly on the pivot points 2, the auxiliary frame 5 moves-lengthwise of at 22 to the lugs onthe supports 3. For the sake of 1 brevity, the parts '16 may be alludedto as :bell crank levers fulcrumed' at 18 on the main frame 1, the bell cranklevers the main frame 1, and as the bed is raised toward the vertical, the frame 5 tends to move downwardly, or to the left in Figure 2, the frame 5 and the bedding 7 upon it,

exerting a pull on the grip 8 and causing the grip to hold the bedding firmly. I During the operation of raising the bed, the lever 16 tilts, the stud 19 moves in the slot 20 of the radius arm 21, and the radius arm swin s a little but durino the raisin of c: 7 a b the bed to a vertical position,no work is accomplished by the radius arm 21 or the i lever 16, aside from the fact that the levers 16 aid in carrying the auxiliary frame 5, becaus they are pivoted at 17 to the auxiliary frame,,-and are pivoted at 18 to the main frame 1. a y i Suppose that the bed is swung downwardly below the position shown in Figure 2. Ultimately, and before the bed reaches the horizontal position, the stud 19 in the lever 16 reaches the upper end of the slot 20 in the radius arm 21. The radius arm 21 then act as stops which cause the levers auxiliary frame,

16 to tilt on their fulcra 1'8 and move the auxiliary frame 5 to the'right in Figure 2, the bed grip 8 being raised, the legs 11 being lowered, and the parts ultimately arriving in the positions shownin Figure 1.

What is claimed is 1. In a device ofthe class described, a support, a main frame pivoted to the supportpan auxiliary frame having means for supporting a bedding, an end member, means for pivotally connecting the end 1 memher with the mainframe, means for pivotthe end member with the the end member being tiltable to constitute a bedding grip, the auxiliary frame being movable longitudinally of ally connecting the main frame tocause the end member to grip the bedding, fulcrumed on the main frame and a bell crank lever to the auxiliary frame, and a radius arm mounted to swing on the support, the hell crank lever having limited sliding connec- -t1on with the radius arm, whereby the radius arm will tilt the lever, move the auxiliary frame longitudinally of the main frame, and

move the end member out of beddinggripping position when the main and auxiliary frames have been swung downwardly to a redetermined point.

2. n a device of the class described, a

support, a 'main frame pivoted to the support, an auxiliary frame, a leg pivoted pivoted to the main frame and to the auxiliary frame, the auxiliary frame being movable longitudinally of the main frame, when the bed is lowered, thereby to swing the leg 7 out of alinelnent with the frames and into a position substantially at right angles to the frames, a bell crank lever fulcrumed on the main frame and pivoted to the auxiliary frame, and a radius arm mounted to swing on the support, the bell crank lever having limited sliding connection with the radius arm, whereby the radius arm will tilt the i move the auxiliary frame longitudi and swing the leg lever, nally of themain frame,

as aforesaid, when themain and auxiliary structed to carry bedding: a bedding-grip pivoted at its lower end directly to the frame, the beddin -grip being pivoted main intermediate its ends irec-tly to the outer end of the auxiliary frame, and the inner end of the auxiliary frame being carried the main frame independently of the support, whereby the auxiliary frame may respond readily bedding when the main :frame is raised, slide longitudinally of the main frame,and

to the weight of the I,

hold the bedding-grip engaged with the bedding.

In testimony that claimthe foregoing as my own, I have hereto aflixed my signature.
