WILLIAM A. MATHESON, OF CHICAGO, ILLINOIS, ASSIGNOR TO BOLL A-WAY BED CORPORATION, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

BED CONSTRUCTION.

Application filed August 8, 1928. Serial 170. 297,649.

My invention relates to beds and has to to do more particularly with beds of the folding type which may be disposed in a recess of a Wall or the like when not in use.

A common objection to beds of this type which are secured to an immovable support and normally disposed in a recess is that when such beds are opened for use, the head portion thereof remains entirely, or at least partially, within the recess. As a result of this the sleepers head lies within the recess, which forms a sort of air pocket in which the ventilation is not such as would be desired for sleeping.

While this disadvantage is overcome by the type of folding bed which may be rolled out into the room, the fixed type of bed has several advantages, such as that it permits greatersimplicity of design and consequent reduction of.cost, and is, in general, easier to manipulate and with a minimum of effort.

An object of my invention is to provide a bed which is fixed to an immovable support and is normally disposed, when not in use, in a recess in a wall or the like and, when desired for use, may be moved out into the sleeping room in such manner that the head portion is substantially clear of the recess.

A further object of my invention is to provide such a bed which is of cantilever construction; that is, which is swingingly mounted on a vertical support, so as to be manipulable with a very slight amount of effort.

A still further object is to provide such a device which is extremely simple in construction, inexpensive to manufacture and at the same time rugged.

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from .the disclosure herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

Referring now to the drawings forming part of this specification:

Fig. 1 represents a plan view of a bed embodying my invention extended for occupancy in a plurality of positions, a portion of a wall with shown in section;

Fig. 2 is a side elevation of such a bed in position for occupancy, the bed in elevated position being shown in dotted lines, and a portion of a wall and floor being shown in section;

Fig. 4 is a sectional view taken on line 4-4 of Fig. 3;

Fig. 5 is a sectional 5-5 of Fig. 4;

Fig. 6 is a plan view similar to Fig. 1 showing a modified form of the invention;

Fig. 7 is a side elevation of the embodiment of Fig. 6, the bed being shown in full lines in elevated position, and fragmentary portions in dotted lines representing the bed extended for occupancy;

Fig. 8 is a section taken on the line 8-8 of Fig. 6;

Fig. 9 is a sectional 99 of Fig. 6; and.

Fig. 10 is a sectional view taken on line 1010 of Fig. 9. r r

A bed embodying my invention when not in use is normally disposed in a recess A a wall 10. Doors 11 and 12 nora recess therein being view taken on line view taken on line formed in mally close the opening 13 to the recess when the bed is disposed therein so as to completely conceal the bed. The main for the bed is rovided by a vertical member which prefera ly is in the form of a post 15 rotatably mounted on pintles 16 and 16' seated in plates 17 and 17 secured to the threshold and upper jamb of the doorway 13. Projectinglaterally from the post 15 so as to be swingable therewith, is a supporting member 18 which may be in the form of a channel bar as shown in Fig. 3. Lugs 20 and 20 are provided adjacent the extremities of the channel bar 18 for pivotally mounting the bed frame 22 at points 23 and 23, suitable brackets 24 and 24' forming a connection between the frame and the lugs.

A gravity counterbalance 25 is mounted on the rear of the bed frame 22 and may take the form of a section of heavy tubing. A leg 26 is pivotally secured to a bracket 27 on the bed frame, a guide ring 29 being sematerial. An arm 87 is rigidly secured to the end of the support 18, and pivotally connected thereto and to the head board 36 is alink 89.

Connected to the bed frame at any suitable place adjacent the rear thereof, these points conveniently being on the gravity counterbalance member 25,

are a pair of springs 10 and 41. These springs are looped at-their other ends into the projecting eyes 42 and 43 of a nut 15 which is threaded onto a headed bolt 46 passing through the uthreaded sleeve 47 formed, in the channel 18.

From the above description, the operation of the bed embodying my invention will be readily apparent. When not in use, the bed will normally be in elevated position as (shown in dotted lines in Fig. 2 and will occupy the recess A and will be concealed from view by the doors 11 and 12. "When it is desired to use the bed, the doors are opened as shown in Fig, 1 and thebed is grasped iat any convenient point adjacent its foot and w as in elevated drawn toward the floor, the bed frame pivoting at points 23 and 28'. By means of this movement, the feet 28, which were disposed parallel to the bed frame 22 when the same position, will be extended to a position at right angles thereto bymeans of the link 31. The leg 26 guided by the ring 29 will at the same time be moved downwardly to the floor, pivoting on the bracket 27. The head board 36 at the same time will be raised and guided by the link 39 so as to occupy a position substantially in prolongation of the head These positions are clearly shown in Fig. 2.

Before the bed is brought completely to the floor, it may be determined at what position inthe room it is desired that it be disposed. As shown in Fig. 1, the entire bed may be pivoted about the vertical axis deter- I mined by the post 15 and moved about this axis at any desired angle and, if preferred, it may be moved entirely clear of the recess A. The bed may be moved in a horizontal plane until the feet 28 and the leg 26 have come in contact with the floor and this occurs only at the limit of the movement of the bed frame toward the floor on the pivots 23 and 23.

WVhen it is desired to dispose the bed in the recess A when not in use, the reverse of the operation described above will be performed. Thus the bed is grasped at any convenient portion adjacent the foot; the gravity counterbalance 25, as well as the springcounterbalances 10 and 41, will exert practically sufficient force to raise the bed with a very slight amount of manual effort, the latter being used mostly to guide the same and prevent jarring of the parts. The bed, after it has been elevated, is swung on its pivot determined by the post 15 into the recess A, whereupon the doors may be closed and the bed entirely concealed.

Referring to the Figs. 6 to 10, inclusive, this embodiment is similar to the one just described, except thatmeans is provided for locating the bed at a desired position in the sleeping room, which means operates automatically when the bed is manually drawn down for use. The bed is indicated generally at 50 and is substantially similar in construction to the one shown in the embodiment of Figs. 1 to 5 and is similarly sup ported. Secured to the floor of the alcove or recess 10 by means of screws or the like is a plate 51 on which is mounted, preferably integral with the plate, a vertical post 52. A bolt 53 is disposed in an aperture 5st near the upper end of the post and is retained by means of nuts 55 and 56 threaded thereon. At one end ofthe bolt 53 and integral therewith is a ball 57 engageable in a socket 58 of a lever 59. As will be clearly seen in Fig. 7, the lever 59 is angular in shape, having a bend which represents an angle slightly more than 90, for a reason which will presently appear. The opposite endof the lever 59 has a socket 60 similar to the socket 58 which receives a ball 61 carried at one end. of bolt 62. This bolt is retained by means of nuts (53 and 63 in an aperture of aflange (55 integral with a collar 66 secured on thetubular counter weight member 25'of the bed, the collar 66 being retained on the member 25 by means of a bolt 67 and nut 68. Obviously, instead of the ball and socket joints disclosed, any universal type of joint may be used.

It will be seen that when the bed is moved from the elevated position shown in full lines in Fig. 7 to the open or extended position shown in dotted lines, the lever 59 will swing it positively in a horizontal plane simultaneously with the downward movement thereof so that when it has reached the fully extended position where it is ready for occupancy the bed will have been swung angularlyaround the pivoted support 1.5 to the position shown in Fig. 6. Obviously, this position will always be the same for a given adjustment of the vertical post 52. However, it will be readily apparent that this position may be changed at will by modifying the position of the post 52 on the floor of the recess and by shifting the collar 56 on thetubular member 25, either of which obviously is a simple operation.

It will be readily apparent that the lever 59 is formed angularly,as shown, for the purpose of accommodating the head portions of the bed 45 and 36 when the bed is in .folded position, as shown in Figure 7.

It will be obvious that by means of the devices embodying my invention the bed will always clear objects disposed along the wall of a sleeping room, such. as radiators. chairs, and the like, and by means of the embodiment shown in Figs. 6 to 10 articles of furniture, etc., may be more or less permanently placed about the room with the assurance that they will not be collided with by the bed when the latter is extended for use, inasmuch as the bed will always occupy a given position. In this embodiment, also, the user is relieved of the labor of shifting the bed about the room to find a suitable position, inasmuch as the bed automatically takes the position which has once been determined upon.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention. For example, any number of spring counterpoises may be employed and 1 do not wish to be limited to two, as shown. Obviously, more than two eyes may be formed on the nut 15 and a corresponding number of springs attached thereto. Hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or uses mentioned.
