The present invention relates to improvements ln chair beds, and has particular reference to apparatus of the character described that may be readily yconverted from a bed to a chair and vice versa from a chair to a bed.

The present application is a continuation in part of my co-pending application, Serial Numtablishing closer cooperative relationship bei" tween the seat deck and the mattress frame, and providing Vgreater clearance for the mattress during the unfolding operation.

Further 'objects and advantages of my invention will appear as the specification proceeds and the novel features of the same will be fully set forth in the claims hereto appended.

The preferred form of the invention is illustrated in the accompanying drawings, formin part Aof this application, in which: l

Figure 1 shows a vertical longitudinal section through my chair bed, in bed position;

Figure 2, a similar section through my chair bed in an intermediate position;

Figure 3, a similar section'through my chair bed in chair position; and i Figure 4, a plan view of a seat deck used in my invention.

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

My chair bed comprises in its principal parts, a main frame l, a foldable mattress 2 and a seat deck 3. The main frame may be of any suitable form, and as here shown, comprises a back 4, side members 5, and a front rail 6, the back and the sides and the front forming a rectangular box adapted to accommodate the folding mattress.

The main frame may be provided with suitable legs l, and bottom slats 8 to support part of the mattress frame. It also has an upholstered chair back 9 hinged to the upper edge of its back, as at l0, the chair back being adapted to move into normal chair-back position, as shown in Figure 3, so as to conceal a portion of the folded mattress frame, and being also adapted to be swung out of the way, as shown in Figure 2, so as to give clearance for the unfolding of the mattress.

The mattress 2 consists of three rigid'sections il, I`2 and I3, hinged together, as at I4 and l5, suitable webbing I5 spanning the frame sections, and upholstery ll uniformly covering the three frame sections, so as to form a uniform sleeping surface when the frame is unfolded, as in Figure l.

The upholstery is made in such a manner that it will readily fold over the hinges M and I5, as shownat I8 and I9.

In this connection it should be observed that the mattress generally is of the same construction as described in my co-pending application Ser. No. 202,480, and contains springs arranged to collapse over the hinges, so as to allow of the folding operations, but at the same time placed under compression so as to yieldingly aid in unfolding the mattress.

The entire mattress may be accommodated in folded condition, in the main frame, with the rear section ll disposed in upright position in the back of the frame, the intermediate section resting in the bottom of the frame on the slats 8, and the front section I3 turned over backwards on the intermediate section.

When in this position, as illustrated in Figure 3, the back is supported by a pair of links 20 having their lower ends pivoted to the main frame,as at 2|, and their upper ends pivoted to the back, as at 22, intermediate the height of the latter. rIhe upper end of the back is further supported by means vof Aa pair of pins 23 projecting laterally therefrom into slots 24 provided in the sides of the main frame, the slots being substantially vertical in their upper ends and curving forward in their lower ends, as shown particularly well in Figure l.

The seat deck 3 comprises a horizontal frame 25 curving downwardly at its forward end, as at 26, and pivoted to the top of the front rail, as at 2l. Handles Y2t project upwardly from the rear of the frame 25 and rest against the rear mattress section when the frame 25 occupies a horizontal position.

The specific construction of the seat deck, which is intended to be very thin, so as to occupy little room, is illustrated particularly in Figure 1, according to which the frame 2.5 lincludes two parallel side bars 29, a rear bar 30, and a front bar 3| connecting the side bars. The space between these bars is occupied by additional bars 32 having a plurality of springs 33 connecting the latter bars with one another and with the frame 25. Suitable cloth material, such as canvas is stretched across the frame, as at 33'.

At the eXtreme front of the seat deck, I provide a cushion strip 34 which extends much more deeply than the remainder of the seat deck, and includes conventional coiled spring construction resting on a horizontal slat 35 supported by the front bar 3l.

The seat deck is connected to the intermediate frame section I2 of the mattress by means of a pair of links 36 pivoted to the seat section intermediate the length thereof, as at 31, and to the intermediate mattress section at a point 38 lying substantially midway between the front and the center of the mattress section.

The links 36 are dimensioned to maintain the seat deck in substantially parallel relation to the mattress frame I2 in normal chair position, as shown in Figure 3. A pry member 39 is provided forwardly of each link 36 on the seat deck frame so as to prevent the links 36 from swinging downwardly when the seat deck is swung upward on its pivot 2l. A slight amount of play is left, however, between the links 36 and the pry members 39 to allow the links 36 to properly function during the initial inverting movement.

In operation, beginning with the position of Figure 3, the operator rs't swings the upholstered back 9 upward in the manner shown in Figure 2,

and then pulls forward on one of the handles 28.

This causes the seat deck to swing forward on the hinge 21 in the manner indicated in Figures l and 2, until the extreme ends of the handle strike the floor. During this movement, the links 36 swing the intermediate frame section I2 upward and forward, through the intermediate position of Figure 2 until it reaches the final horizontal position of Figure 1.

The intermediate frame section pulls forward the lower end of the back section II during this movement, and the latter section is guided by the links 2i), and the slots 24, into a position of horizontal alinement with the intermediate section, as shown in Figure l.

The front section I3 may then be turned 'for- Ward on its hinge I to complete the bed.

It should be particularly noted that, in the position shown in Figure 3, the upper edge of the front section I3 is pressed downwardly by the seat deck, so as to place the mattress upholstery under compression, and that the front section extends above the bottom of the cushion strip 34.

It should further be noted that, due to the action of the links 36 and the pry members 39,

the pivot I5 at the front of the intermediate frame section I2, is raised to a considerable height above the front rail 6 when crossing the vertical plane of the latter, so as to give ample clearance for the operation as illustrated in Figure 2, the pivot I5 rises a considerable distance above the normal height of the seat deck and above the horizontal plane of the pivot 3T when the seat deck is in chair position.
