WALL BED.

Application fl1ed September 15, 1924. Serial No. 737,661.

My invention relates to improvements in Wall-beds. It is of particular service in connection with that type of upending wall- .which may be conveniently swung on a vertical axis when folded or unfolded; to provide a construction the mani ulation of which is exceedingly simple an requires a minimum of effort in its manipulation; to provide a construction which, while being easy to operate will be safe against accidental folding when in use as a bed; to provide a structure which will securely retain its folded position when folded; to provide a construction which shall be neat in'appearance, rugged and durable, sim le in design, economical to manufacture anrftrouble-free, and in eneral, to provide an'improved wall bedstea of the character referred to.

In the drawings which illustrate my invention as applied to a wall-bed adapted to swing through the door of a closet,

Fi 1 is a side elevation of the structure showing the bedstead extended or unfolded.

the line 5--5 A 7-7 of Fig. 3, and

Fig. 8 is a section taken on the line 8-8 ofFi 1.

Refining to the drawings, 10 represents a portion of the jamb of the doorway through which the bedstead with its sup porting structure is adapted to swing. Said swinging connection is in the present instance afforded through the medium of a tubular standard 11, to which the structure is secured, and which standard is supported at its upper end by a bracket 12, and at its lower end by a pedestal 13. As shown best in Fig. 7, the pedestal 13 comprises a casting which is bolted to the floor of the room, said pedestal having a boss 14 bored out to rotatably receive thereduced end 15 of a pivot stud 16 fitting the interior of the tubular standard 11 and secured therein by means of a transverse, diametric pin 17. The pivotal connection of the upper end of the tubular standard 11 is effected by securing in the upper-end of said standard a pivot stud 18, having an upper reduced extension 19 r0 tatable in the projecting lug 20 formed as a part of the bracket 21. Said bracket 21 is secured to the amb 10 by means of suitable wood screws as at 22.

There is looped around the upper end of the standard 11 a length of angle iron, the horizontal flange of which is cut away so that it will fit the. standard 11', as indicated in Fig. 5. Adjacent the standard, the uncut portions of the said flange are connected together by riveting thereto a short strapmember 23. The outer ends of the vertical flanges 24 of said angle iron are bent in opposite directions, as indicated at 25 and Y A pin 30 extending diametrically through the standard and portions of the flanges 2 1 of the arm 28 serve to lock said arm rigidly to the upper end of the standard.

A lower arm 31 similar in construction to the arm 28 is secured to the lower end of the standard 11 by means of the diametric pin 17 previously described, the outer end of said arm 31 being similarly secured to a length of angle iron 32 below the angle iron 27 and parallel thereto. The angle irons 27 and 32 are suitably secured as by bolts 33 to somewhat larger and longer similarly extending angle iron bars 3 1 and 35,'which structure, the vertical members of which are designated 36 and 37.

To the verticals 36 and 37 there are secured, for example, by means of bolts 38 (see Fig. 5), the post members 39 and 40 of anornamental head frame shown best in Fig. 3, said head frame moving with and constituting a part of the swinging, supporting structure. I To the lower ends of the verticals 36 and 37, there are secured, for example, by means of bolts 41, a pair of outwardly extending substantially horizontal angle bars 42 which may conveniently be made of asingle piece of angle iron, the intermediate portion-of which constitutes a cpnnecting cross bar 43, for the outer' end of saidextensions 42. As shown, the extensions 42'are spaced slightly from the floor surface 44 so as not to interfere with the swinging of the main structure around the axis'of thestandard 11. The outer ends of said bars 42 are maintained in vertical posipivoted at its lower end on a pivot 49, fixed in the end of the bar 42 adjacent the junc-' tion of said bar 42 with the vertical frame "preferably tubular. Each of said tubular side bars 51 carries at its ends, risers 52-53,

member 36.

The principal supporting elements of the bedstead proper designated as a whole 50, comprise a pair of side longitudinals 51 of any desired form but preferably constructed of forged angle iron. To the outer ends of said risers 53 there is secured an angle iron cross bar 54 to which one end of the bed fabric 55 is connected through the medium of helicals56. To said cross bar 54 there is also secured a bail shaped rod 57 which constitutes a stop. for the inner end of the mattress 58.

- To the-outer end of the risers 52- there is similarly secured a cross bar 59 to which the outer end of the bed fabric 55 is similarly connected. Also, to said cross rail 59 there are secured a pairof bedding clamps 60 of a construction well known to those skilled in the art. The risers 52' also serve as supports for plates 61 secured thereto, said plates being fastened to the inner side of the vertical post members 62 of the ornamental foot end frame designated as 'a whole 63. As is usual with bedsteads ofthis up-ending type, the legs of theouter end of the bedstead are adapted to fold as indicated at 64 in Fig, 2. Said folding connection comprises a slotted filler member 65 secured in theupper end of the folding leg 64 by the pin 66. The

balance the weight of the structure.

sliding movement when the outer end of the bedstead is elevated.

There are provided as an important feature of the construction, a series of balancing or assisting springs, such springs which are of the helically coiled wire tension type having their lower ends hooked into apertures punched inthe vertical flange of a cross angle 68 secured to the lower extension bars 42 of the supporting frame at points intermediate the pivots 46 and 49. The upper ends ofsaid helieals 69 are hooked into apertures punched inthe upper flange of an angle iron crossbar 70, secured to the side bars 51 of, the bedstead, by means of an intermediate angle-iron 71 riveted to the upper surfaces of said side bars 51.

As shown best. in Fig. 1, the upper ends of the helicals 69 are thus connected to the bedstead at a point located a substantial distance above the center line of the side bars 51, through which center. line passes the axes of the pivots 72 and 73 of the upper ends of links 48 and 47. The construction of said pivot connection 72 and 73 is best shown in Figs. 5 and 8, and it will be also observed by reference to Fig. 1, that the upper endsof the springs 69 occupy a position intermediate the pivots 72 and 73, in the present instance slightly closer to the pivot 72.

The dimensions of the various parts are such that when the bedstead occupies the pothe pivot 72 rapidly swings outwardly as shownby the dotted lines in Fig. 2, so that by the. time the end of the bedstead attains an elevation, such that it is difiicult to manage without considerable assistance, the

lifting tendency of the sprin s has been increased toa point where it will substanti ai ltlly e dotted line position in Fig. 2 indicates approximately the position of equilibrium. WVhen the bedstead is further elevated the center of gravity of same finally moves inwardly of a vertical plane passing through the upper pivot 73 of the outer link 47, and hence in the full line position shown in Fig. 2, the bedstead will maintain itself seeurely in folded position, even though in such position the springs 69 are completely relaxed; However, in order to prevent the springs from unhooking, I preferto make them of such len th that there is a very slight pulling tendbncy, even when the bedstead has attained the vertical position shown in Fig. 2. i

Since the described details of construction and operation are illustrative of merely a single embodiment of my invention, the scope of same should be determined by reference to the appended claims, said claims being construed as broadly as possible consistent with the state of the art.

I claim as my invention:
