ALBERT W. SMITH'AND .WILLIAM J. DUVALL, OF ST. LOUIS, MISSOURI.
Application filed October 18,1922. Serial No. 595,260.-
To all whom it may concern.
Be it known that we, ALBERT WV. SMITH' and lVILLIAM J. DUVALL, citizens of the United States, residing at the city of St. Louis, in the tate of Missouri, have invented certain new and useful Improve mentsin Beds, ofwhich the following is a specification. i
The object of this invention is to provide a bed adapted for use as what is known as a wall-bed or an in-a-wall-bed, which shall be of the simplest form of construction and devoid of the cumbersome and special head and lifting parts heretofore common in such constructions. Such beds now on the mar ket are usually provided with a separate head-piece for the lifting and balancing members, which extra head-piece projects to the rear of the head proper and takes up a material amount of room, whichis an extremely undesirable feature in a wall-bed or similar structure. The said extra projecting part is a source of large expense, not only because of the material and labor embodied in it, but also because of forcing the provision in the building of an apartmenthouse or the like, in which the same is to be used, of closets or receptacles of large dimensions,'in'order to receive a wall-bed having such a rear projection.
Among the merits of the present invention may be mentioned the inclusion" between its head and foot of the necessarylifting and balancing devices and means for holding the mattress from slipping, whereby less room will be required within the wall of a building to receive the same when This is of the greatest importance, because it permits greater use by an architect and builder of the available land area and it allows the construction of apartments or the like on lots of land that would otherwise be too small or it enables.theprovision in such buildings of larger and more commodious rooms.
Moreover, this invention can be attached to practically any standard or stock bed, and the same thereby be converted into a wall-bed or the like, which saves much in the way of special parts, special manufacture, machinery, and equipment. I
WVhile this bed is primarily intended as a wall-bed, yet other uses are possible.
In the accompanying drawings forming part of this specification, in wh h li e numbers of reference denote like parts wherever they occur,
Figure 1 is a side elevation of .the bed extended;
Figure 2 is a side elevation of the same folded'and' attached to a'door or other movable wall-piece; and
' Figure is a vertical transverse sectional view on the irregular line 33 of Figure 1.
When used as a wall-bed the head 1 of the bed may be attached in any desired manner tothe door 2. Then temporarily not in use, thebed will be caused in any desired manner to be withdrawn into the alcove, closet, or recess provided for that purpose.
The foot 3 of the bed is preferably pivoted at 4; to the main frame 5. The box-spring 6 and the mattress 7 rest upon bed-bottom frame 5. This bed is not restricted to the use ofa boxspring, but may be variously equipped. v
Preferably a projection 8, which may be limits the travel of the box-spring 6 and the mattress? or a substitute for the same in the direction toward the head 1 which results when the parts are moved to the position shown in Figure 2 with the spring 6 or the mattress in'its place resting thereon, and, also, limits their downward movement.
, The frame 5 is supported upon the floor when the bed is open, asshown in Figure 1, by the foot 3 resting on the floor, the rods 9 and 10, pivoted in the plate "4, swinging from the position shown in Figure 2 to that shown in Figure 1, for the purpose of allowing foot 3 to occupy the position shown in Figure 1.
At the other end the frame 5 is supported by the frame 11, fixed'to the head 1, which in general extends from one side of the bed to the other and is pivoted at' 12 to the side members of frame 5 on each side. Indirectly frame 5 is supported by the head 1, which rests upon the floor, but the connection therebetween is by means of the frame 11, springs 18,rod or plate 14, and links 15,
rods 20. To the upper part or rod 21 of frame 19, pivoted at 29 to end projection 8, are attached by hooks or eyelets 22 a plurality of rods 23, which are telescoped'by'hoh low rods 2-l-, and are adapted to move longitudinally therein, ascending when the bed frame 11 and the frame 28, of which rod or plate 14 forms a part. Frame 28 is pivoted at 30 to head 1, similarly the hooks 17 on links 15 form another pivotal connection for frame 28, hooks 16 forming a pivotal con nection between the end member 18, connect ing the end projections 8 of the frame 5, and the links 15; Furthermore, frame 11 is pivoted at 12 to the sides of frame 5.
Thus the bed bottom 5 is adapted to rotate on pivot points 12 on both sides of frame 11, the degree of its said rotation being indicated by the change of position depicted in Figure 2 as compared to the position shown in Figure 1.
By this construction it is possible so to arrange springs 13 and the various pivot points just mentioned that a'slight upward impulse conveyed to the foot 3 of the bed will cause the bed to rise to the position shown in Figure 2, because the springs 13 will do the major part of the lifting. The movement forward or backward ofthe pivotal points at hooks 17 and 26 will provide adjustment that will accommodate any alteration in weight or load or material of manufacture. One of the greatest advantages of this construction is that the springs 13 are not under constant tension; nevertheless, whenever it is desired to close the bed they immediately exert their pulling force. In other beds the lifting springs are under constant tension, which necessarily reduces the length of their life, and, also, reduces theirresiliency and tends to produce the objectionable feature of the danger that at any time there may be a broken spring.
The feature of the springs 13 not being of pivoting may be practiced, as, for instance, the hooks may be eyes; the hooks herein shown may be placed upon the other members i reverse arrangement from what is herein iown; or other means for pivoting may be used.
This constructionis adapted for use in davenets and similar beds or couches.
Having thus described this invention, we hereby reserve the benefit of all changes in form, arrangement, order, or use of parts, as it is evident that many minor changes may be made therein without departing from the spirit of this invention or the scope of the following claim.
A bed comprising a stationary head presenting a plurality of hollow rods spaced laterally across its upper portion, a bed bottom pivoted to'the said head for movement into a vertical position, a frame composed of a plurality of curved rods arranged between the said stationary head and the pivoted end of the said bed bottom with its lower part pivoted to the said. bed bottom, said frame being adapted to move vertically of the said stationary head as the said bed bottom is raised and lowered and being of such curvature as to close over the lower endof the bed bottom in the upended position of the latter, and a plurality of rods slidably engaged within the said hollow rods ofthe stationary head. and connected to the said frame for movement exteriorly of the hollow rods as the said frame is moved downwardly, said rods being adapted when extended from the hollow rods to form continuations of the said hollow rods.
In testimony whereof we hereunto aflix our signatures.
