UNITED STATES ALBERT ERNEST, 0F PAXTON, ILLINOIS.y

FOLDING BED.

Application filed February 28, 1916.

To all whom t may concern:

Be it known that I7 ALBERT ERNEST, a subject of the Emperor of Germany, and a resident of Paxton, in the county of Ford and State of Illinois, have invented certain new and useful Improvements in Folding Beds, of which the following is a specifica tion.

My invention relates to improvements in folding beds, more particularly folding beds of the type in which the bed is normally turned into a vertical position during the day-time, and then lowered into a horizontal position at night-time. l

The principal objects of my present invention are to provide improved means for bringing the bed from a vertical position to a horizontal position; to provide Vmeans whereby in addition to turning the bed .from a vertical position to a horizontal position, the bed is simultaneously given an additional forward movement; to provide means whereby receptacles may be arranged in front of the bed when in its vertical position; to provide means whereby these receptacles may be moved with the bed without interfering with the normal horizontal position of the receptacles; to provide improved means for increasing the effective length of the bed as compared with the length of the bed when in its vertical position; to provide means whereby a bed and a receptacle, such as a bookcase, may be conveniently combined in a single structure, and generally, to improve, simplify and cheapen the construction of folding beds and combined folding beds and receptacles.

In attaining these and other objects to be hereinafter described, I have provided a construction one embodiment of which is illustrated in the accompanying drawings, in which Figure 1 is a vertical section through the combined bed and bookcase with the bed folded away;

Fig. 2 is a view similar to Fig. 1 showing the bed in its horizontal extended position;

Fig. 3 is a' section on the line 3--3 of Fig. 2;

Fig. 4 is a section on the line 4--4 of Fig. 2; and

Fig. 5 is a section on the line 5-5 of Fi 2.

Fig. 6 is a detail view of a portion of the device.

The structure illustrated in the drawings Specification of Letters Patent.

includes a pair of

bookcases

10, 11, a disk 12 and a container 13 for papers or the like arranged one over the other when the bed is in its vertical fposition, as shown in Fig. l. The bed includes an upper member 14 and a lower member 15 which supports the springs 16 on which the mattressV rests. When this bed 14 is moved outwardly, the desk 12 and the upper bookcase 10 tswing outwardly with the bed `so that when the bed is in its extended position, as shown in Fig. 2, these parts are held suspended underneath the bed. The uppermost container 13 is moved outwardly and then turned upwardly out of the way of the end of the bed, as shown in Fig. 2. The bed is connected to the side walls 17 of the frame work of the structure by means of two pairs of

links

18 and 19. The link 18 is pivotally connected at 21 to ya plate 20 attached to the wall 17 of the structure. Similarly the link 19 is pivotally connected at 22 to a plate 23 attached to the side wall 17 of the structure. The'link 18 is connected at its other end to the bed at the point 24, while the link 19 is connected to the bed at the point 25. These links are so arranged and proportioned that if the upper (Fig. 1) end of the bed is moved outwardly, the lower end of the bed moves not only upwardly, but outwardly as well into the position shown in Fig. 2. The object of this outward movement is to increase the effective length of the bed. rIlhis is accomplished by means of the

links

33 and 34 which support the head of the sleeper when the bed is in its extended position, as shown in Fig. 2. The link 33 is pivotally con nected to the bed at the point 24, and a shoulder 52 is provided to prevent the link 33 turning through a greater angle relatively to the bed than that shown in Fig. 2, which is the angle found to be most suitable in practice. These

links

33 and 34 are preferably formed of angle iron so that the link 33 supports the link 34 as a whole when the bed is in its extended position. For guiding the end ofthe link 34 a slide 35 is provided in which runs a boss 36 (F ig. 5) connected to the link 34. 'Io act to some extent as a counterweight for the weight of the bed, a spring 27 is provided connected at one end to the member 47 at the rear lower edge of the structure by the pin 28, and at the other end to va chain 29 passing around the

pulleys

30 and 31. The 'other end of the chain is` connected to the mid-point of the -link 19 at the point 32. It will be evident that when the bed is pulled downwardly the spring' 27 is extended so that the latter will aid subsequently in the lifting of the bed structure.

On the otherhand, the spring tends to check the movement of the bed as it approaches the vertical position, Vand so prevents the bed slamming against the back wall of the structure. This double function of the spring is due to the fact that the point 32 to which the chain 29 is connected moves from one side across to the other side of the line adjoining the point 22 to the peripheryl of the pulley 31. As the spring tends to throw the bed forward when the latter is in its vertical position, a catch. may bevprovided to hold the bed in its desired vertical position, particularly when the desk is being used. Y

In order to avoid constructing the structure asa whole of excessive height not only is the bed portion 14 arranged to move outwardly as well.as downwardly when unfoldingthe bed, but also an extension 37 is provided which is connected to the outer end of the bed proper 14 by means of a link 38. This extension is supported at its outer end by legs 39 connected thereto by hinges 40. This extension 37 and its legs 39 are folded on top of the bed before the latter is moved into its vertical position, as shown in Fig. 1. Spring catches 48 and 49 are attached to the parts 14 and 37, respectively, `for detachably folding the parts 14 and 37 in their folded position relatively. to each other.

The bed 14 is supported at its inner endV b meansI of the link 18, and the extension 3??7 is supported at its outer end by the leg 39. The links 37 and 38 are of angle iron so that the latter cannot fall'below the horizontal position shown in Fig. 2.V In order, however, to support the outer end of the bed 14 a leg 41 is provided pivotally attached at 42 to the arm 43. The leg 41 is Vas shown most clearly in Fig. 2, whiley the bookcase 10 is similarly pivotally connected at 44 to an arm 45 which also projects downwardly from the1 underside of the bed. The pivot points 42 and 44 are arrangedL substantially Vvertically above the Vcenters of gravity of the desk and bookcase, respectively, so that these parts retain their normal horizontal position asa whole7 during themovelrnentf Qt the bed, from itsI vertical to its horizontal position, so that the contents of these receptacles are not spilled on the floor. A link 46 connecting the desk and bookcase tends to prevent swinging of Y one or other, or both, of these receptacles above the points of suspension 42 and 44 respectively. This link 46 prevents the receptacle 42 swinging for the reason that when the bed is extended the pivots 44 and 61 are in a straight line with the link 46 so that movement of the link 46 to the left (Fig. 2) which must occur if the receptacle 12 is toswing is almost impossible as the turning movement on the receptacle 10 produced by pulling the link 46 is zero. This link also prevents in very large measure the swinging of the receptacleV 10 as the pivots 62 and 63 are nearly in line so that the turning moment on the receptacle 12 produced by pulling. the link 46 to the rig-ht (Fig. 2) is very. slight.

The book case 10 is preferably provided with rollers 50 and 51 on its underside to facilitate movement forward or backward along the top of the book case 1l.
