J. D. BELL DIVAN BED Filed Dec. 17, 1938 2 Sheets-Sheet 2 INVENTOR,

Patented Jan. 20, 1942 UNITED STATES PATENT OFFICE DIVANTBED Joseph 1). Bell, San Francisco, Calif.

Application December 17, 1938, Serial No. 246,510

13 Claims The present invention relates to improvements in divan beds, and is a continuation in part of my copending applications, Serial Numbers 124,050, filed Feb. 4, 1937, which issued as Patent No. 2,248,603 on July 8, 1941; 202,480, filed April 16, 1938 and issued July 15, 1941 as Patent No. 2,249,266; and 210,888, filed May 31, 1938.

The principal object of the invention is to provide a device of the character described which may be readily converted from a divan into a bed and vice versa.

A further object of the invention is to provide a divan bed which, when used as a divan, provides a relatively low seat so as to permit the use of loose cushions for building it up to normal seating height, and which, when converted into a bed, raises the seat to bring it up to convenient bed height.

It is further proposed to provide suitable opcrating mechanism for the divan bed which al-' lows changes to be efiected with a minimum of efiort.

Another object of the present invention is to provide extension means for the divan bed which may be concealed under the seat when the device is used as a divan and which may be projected forward for increasing the length of the bed.

While the term divan is commonly used to signify a body rest of the sofa type, with room for two or three persons it should be understood that the principles of the present invention apply also to a single seat body rest, such as'a chair.

Further objects and advantages of my invention will appear as the specification proceeds.

The preferred forms of my invention are illustrated in the accompanying drawings, in which:

Figure 1 shows a perspective view of a preferred form of my divan bed, with upholstery omitted;

Figure 2, a perspective view of a modification of the form shown in Figure 1;

Figure 3, a side elevation, partly in section, of the form shown in Figure 2; and

Figure 4, a perspective view showing the form shown in Figure 2 in divan position, and Figure 5, a side elevation, partly in section of the form shown in Figure 2, in chair position.

While I have shown only the preferred forms of my invention, I wish to have it understood that various changes or modifications may be made within the scope of the claims hereto without departing from the spirit of my invention.

bed I comprises a main frame consisting of two side pieces or arm rests 3, a rear member 4 and a front member 5, the latter being somewhat lower than the former and both cooperating with 1 the arm rests in forming a rectangular box 6.

It also comprises a movable mattress frame, which latter is made in two sections 8 and 9, and which will be referred to hereinafter as the back and seat sections, respectively, and having hinged connection at l0. The hinge is arranged to allow the two sections to assume a position of angularity as in Figures 1, 3 and 4 and to swing into positions of partial or full alinement, as in Figure 2.

The back section receives its principal support in two links I I, which are pivoted,- at their lower ends, to the side pieces 3, and at their upper ends, to the back section intermediate its height. When the back section is in upright position, as in Figure 4, the two links are also substantially upright and lean against the rear member 4 of the main frame. From this position they are able to move into a forward slanting position, as shown in Figures 1 and 3.

For guiding the lower portion of the back frame, I provide another pair of links l2, which are pivoted to the side pieces, as at l3, and to slotted brackets 14 disposed on the back frame near the hinge connection. These links are capable of swinging from a slightly inclined position to the substantially vertical position of Figures 1 and 3, and when in the latter position, form a prop for the center portion of the extended bed near the hinge.

To guide the seat upward during its forward movement, I provide shoes 32 which have slanting faces 33 riding on the front frame members 5 and thus lift the front section into alinement with the rear section as shown in dotted lines in Figures 1 and 3. The shoes 32 may have a more decided cam angle near their points 34 to cause the seat to drop back on return movement with a certain locking action. The rear section of the shoe is flat as shown at 35 to rest on the member 5 when the bed is fully extended.

Figure 1 further shows an extension frame hinged to the forward edge of the seat section and provided with folding legs 46 at its front edge to support the latter when the extension is in alinement with the seat and back as shown in dotted lines.

When the seat is retracted, with the back in upright position, the extension 45 with its folding legs, may be swung underneath the seat for In the forms shown in the drawings the divan 1 accommodation-"within the box, the extension being then disposed between the shoes 32, which latter may be referred to as legs for supporting the seat in raised position.

Figures 2-4, inclusive, show, in different views, a bed-divan essentially similar to that of Figure 1, except that upholstery has been added to give a clearer understanding of the entire structure and that a few modifications have been introduced.

The extension 45 is hinged to the front edge of the seat frame, as at 55, with an offset which brings the extension rather higher in bed position and also allows of accommodation of the bottom frame 52 underneath the extension.

The bottom frame is more in the nature of a real bed frame, with two legs and a top member and bracing members, as illustrated,'and is hinged to the extension by means of two pairs of links 53 and 54 which allow the frame to be swung from a vertical, bed-supporting position to a horizontal position underneath the extension, as shown in Figure 3, so that both the bed frame and the extension may be swung underneath the seat section 9., v

The shoes shown in Figures 2 and 3 differ from the shoes 33 shown in Figure 1 insofar as a slight S-curve is imparted to the central portion 55 of the shoe, between the end portions 34 and 35 thereof. Careful experimentation with shoes of diiferent shapes have proven that a slight S-curve imparted to the intermediate portion of the shoe will effect a somewhat better balance for the whole divan during intermediate positions than a straight intermediate section.

It will be noted that the extension has a crossmember 60 Figure 2 at the free end thereof, which may be the front edge of the extension, and that the front wall 5 of the box has a rod or guide 6| Figure 3 projecting rearwardly therefrom in a downward slanting direction. This guide gives sliding support to the cross-member when the seat is lowered from the upright position of Figure 3 with the extension folded underneath the same. 7

In operation, beginning with the dotted line position of Figure 1, a person may swing the front edge of the seat upward on the hinge I0, swing thelegs 46 underneath the extension frame 45 and the latter underneath the seat and again lower the seat to allow the shoes or legs 32 ,to

come to rest on the front board. He may then' lift the rear overhang of the back frame section 8 which causes the links H to swing backward to a vertical position so as to lean against the back board 4, while the links l2 move backward to a rearward inclined position, and the shoes 32 ride downward on the front rail to alowered seat position. Rearward pressure on the back section 8, when in chair position, will bring about a reversal of the movement back to a position of,

horizontal alinement. Any desired change in angularity may be readily effected by a chair occupant by mere changes of weight distribution.

When an occupant, in chair position, presses against the upper end of the back for increasing the angle between back and seat, the seat moves forward, causing the shoe to ride upward on the front rail 5. This rising movement necessarily intensifies the friction between the shoes and the front rail and brings about a braking action which tends to give the occupant better control over the movements to be effected. The shoes and the front rail may be referred to properly as cooperating braking members.

I claim:
