SOFA-BED OF THE DAVENPORT STYLE.

Specification of Letters Patent.

Patented June 4, 1912.

Application filed January 4, 1912. Serial No. 669,361.

To all whom it may concern:

Be it known that I, HARRY CHnssLER, a citizen of the United States of America, and a'resident of New York, county and State of New York, have invented certain new and useful Improvements in Sofa-Beds of the Davenport Style, of which the following is a specification.

This invention relates to novel sofa-beds of the davenport style. During day-time such acombination sofa resembles an ordinary sofa in appearance and occupies relatively small space, while at night it may be transformed into a bed, usually by unfold- Tt is the special object of this invention to produce a convertible sofa which is provided with mechanism to turn over the seat and simultaneously move the back and place it side by side with the seat. Accordingly the transformation of the sofa into a' bed is accomplished by one simple operation and mattresses may be provided on the rear of the back, which are also turned down by the single operation of the device, so that the entire transformation may be effected in a few moments. The mechanism for transforming the sofa. into a bed is of such construction that it forms two bottom supports or feet at each side of the sofa.

In addition to the above main advantages, it has been sought to produce an article that is an ornament to a room. The operative mechanism is so simply constructed and occupies so little space that there is no indication whatsoever of same in the finished sofa, and the increase in the cost of production is accordingly so slight as to be negligible in an article of this kind.

In order to make the invention entirely clear, reference is made to the accompanying drawing, in which:

Figure 1 represents somewhat in perspective view a sofa-bed of the davenport style. Fig. 2 illustrates the inner box frame in side elevation with back and seat in the same position as in a sofa, and Fig. 3 shows in side elevation the inner box frame with back and seat as in a sofa-bed.

Similar characters of reference denote like parts in all the figures.

In the drawing A, B, C represent the frame of the sofa-bed, which covers the inner box frame D, while E is the back of the frame. The brackets F shown in Figs. 2 and 3 are secured in the rear portion of At each side of the front portion of the I sofa-bed a hinge I is provided, one member of which is secured to the frame D near its front end and the other member to the bottom end of the seat.

For the purpose of converting the sofa into a bed by one movement or operation, two connecting braces J are secured one at each side. This connecting brace J is of peculiar shape, it is substantially S-shaped, as shown, and connected to the seat and back in well defined locations. One end of said brace-is connected by means of a pivot K to the back, somewhat beyond the middle and near the rear side, as shown. Near the bottom-end portion of the back the brace is curved and-continues at practically a right angle to the first described portion to near the top surface of the seat. Near the middle portion of the seat there is a second slight curve in the brace and at the end of same a second pivot L secured in the seat. The brace continues in a straight line to the bottom surface of the seat and then forms a slight curve and extends downwardly for a certain predetermined length. The brace as described is in the location found in the sofa-bed when same forms the sofa, as shown in Fig. 2. Two mattresses M, N, are held in position on therear of the back. The mattresses are connected at their inner ends and the mattress resting on the rear side of the back is held in position by means of two short braces at each side. The second mattress is held in position by means of two somewhat longer braces P at each side, extending from the free end portion of same over to the sides of the back.

To facilitate the working of the operative mechanism, the grip Q, is secured to the rear side of the seat in. the center. When this grip is pulled up, the seat moves on the hinges I and the pivot L by virtue of the connecting brace J, which moves on said pivot in the direction of the semicircle and the arrow shown in Fig. 2. Simultaneously the back moves on the pivot K in the arc of a circle with arrows, shown in dotted lines in Fig. 2. As soon as both the back and the seat assume a horizontal position side by side as shown in Fig. 3, the turning movement of same is at an end because the connecting brace J is so constructed as to form a support or foot by means of the large curved portion R, which rests on the floor. Furthermore, the end portion S of said brace extends downwardly from the seat and is ,of such length as to form a second support or foot, as shown in Fig. 3. In this manner two supports or feet are formed at each side of the sofa when same has been transformed into a bed. Now the holding braces O and P of the mattresses are released and the mattress N placed over the top side of the seat.

' position, shown in Fig. 1.

Thus the sofa may be transformed into a double bed by one simple operation in a few moments. As described, this is effected particularly by means of the peculiar construction of the connecting braces J, the hinges I and the pivots L, K. The entire operative mechanism forms a permanent part of the sofa and, therefore, nothing can be lost or mislaid.

In order to transform the double bed again into a sofa, the mattress N is secured. to the back. Then both the back and seat are moved by pulling the grip in an upward direction until both assume their original It is evident that the form of the connecting brace, the location of its pivots and of the hinges on the seat and back are important features for attaining the desired results in a quick and reliable manner. The mattress, however, and the other details may be arranged in various manners without de parting from the spirit of the present invention.

I claim 1. A sofa-bed convertible by a single movement comprising essentially a frame, a

- seat and a back, and two substantially S- shaped braces one on each side, a pivot attaching one end portion of each brace cen trally to a side of the back, a pivot attaching a second bent portion adjoining the center of the seat to same, and ahandle in the rear center portion of the seat'whereby the back and seat are simultaneously moved toward the operator when forming a bed out of the sofa.

2. A sofa bed convertible by a single movement; comprising essentially a frame, a seat and a back, supporting brackets for the back, two pivots in the rear bottom end portion of the back connecting with said brackets, two hinges connecting each a frontbottom portion of the seat and the frame, and two pivotally secured substantially S- shaped braces connecting the back and seat and forming feet when a bed has 7 been formed.

3. In a sofa-bed a movable seat and back, two substantially S-shaped braces one at each side of said seat and back, a pivot in each side of the back engaging one end portion of said brace, a second pivot in approximately the middle of the side of the seat engaging the adjoining portion of the brace, and a handle in the rear portion of the seat by which the back and seat are movable in one operation, said braces being so shaped as to form two feet when the sofa has been transformed into a bed.

4. In a sofa bed operative mechanism for converting same by one movement, comprising essentially two substantially S-shaped braces connecting said back and seat each consisting of a straight rear portion with its end pivotally connected to the side of the back, a portion curved at about a right angle thereto, a second straight portion pivotally secured to the side of the seat, and a slanting end portion, said first curved and said end portions being adapted to form feet when the sofa has been transformed into a bed.

Signed at New York, N. Y., this 3rd day of January 1912.
