Renewed December 2, 1931 25 Claims.

This invention relates in general to a folding chair and davenport structure and has more particular reference to a chair bed in which the sections are contained when folded below the seat and behind the back of the chair.

One of the principal objects of the invention is in the provision of a chair or sofa construction in which the seat is overturned and the bed sections are slidable outwardly from behind the back and under the seat. A further object of the invention is in the provision of a connected reversible seat structure which is overturned in sliding the other sections from below the seat and behind the back.

A still further object is in the provision of a fixed upholstered back which is engaged by a spring section and slidable behind it for adding to the resiliency of the back. Another object of the invention is in the provision of an improved spring counterbalance at each side of the frame for assisting in opening and cushioning the closing action of the seat section.

A further object is in the provision of a reversible seat structure and a stop for holding it in an inclined position. Other objects are: to provide an improved automatic folding leg; to provide a divided guide rail at the sides of the frame; to improve the mounting of a spiral spring bed section in the frame of a folding bed so that 0 either side of the spring section may be used;

and in general to produce the folding bed structure herein shown and described.

In the drawings, Fig. 1 is a sectional elevation of a folded chair bed constructed in accordance with the principles of this invention; Fig. 2 is a view of the bed in partially open position; Fig.

3 is a view of. the bed in its distended open position; Fig.4 is an enlarged detail of the spring operating mechanism; Figs; 5 and 6 are closed and open views respectively of a similar bed in" which the seat is extended in advance of the other sections without overturning; and Figs. 7 and 8 are closed and open views of a similar bed in which the seat section is first overturned and is then pulled out in advance of the other sections.

Although the present invention is particularly adapted for a folding bed structure of the chair bed type, it may also be used for a wider type of seat, such as a sofa or davenport without changing the structure or method of operation.

In a coil spring folding bed, it is difficult to dispose of the folding sections and still produce a seat which is sufliciently low or close to the floor. Particularly is this true of the present type of folding sofas or chairs which include a loose cushion for the seating surface.

The present invention overcomes this objection by providing an invertible seat section and by sliding the other sections one below the seat and the'other in a vertical position at the back of the frame, engaging the rear of a fixed and upholstered back in such a manner that the coil springs of this vertical section engage the back at the rear thereof, adding the resilience of the springs of this section to the back and pressing the back forwardly.

Referring more particularly to the drawings, a pair of side frames 10 are connected at the back by fixed cross pieces 12 upon which an upholstered back 11 is mounted. This back may sag loosely from cross pieces 12 as shown in Fig. 3, but when engaged by the upright bed section the back will be distended, as shown in Fig. 1.

At the insides of the frame 10 are guide rails 13, 1 1, and' 15, a portion of the latter extending below the other two and the rail 14 terminating at its lower end at a distance from the lower rail 15. The upper ends of the rails 13 and 14 extend upwardly behind the back 11 and together these rails form a guide forsliding, guiding and retaining the bed sections within the frame. The bed comprises a seat section 16, a middle section 17, and an outer section 18. Each section comprises a coil spring frame mounted in marginal or end frames so that both ends of the coil springs 19 in one ofthe sections, as seat section 16, are free and may be utilized for spring movement, the coil spring section being usually covered or enclosed by a fabric cover or container 20.

Supporting the middle bed section 1'7 is a frame 21 which carries rollers 22 and 23 at each end for engagement in the guideways and supporting the outer bed section 18 is a frame 24 having an eictension 25 directly pivoting item a pin 25' at the ends of the .frame 21 for moving the frames .together, the frames being held in alignment by the butt 25 on the extension 25. The frame 24 carries a pivoted leg 26 at each end limited in its supporting position by a stop ,24 on the frame 24, and having a roller 2'7 at its free end-for engaging the guide rails 13 and 15 when the leg is folded.

Theseat section has a frame 28 pivotally mounted at the outer end of a lever 29 at each side of the frame 10, each lever being pivoted at its lower end to the frame adjacent a spring supporting block 30 which has opposite curved surfaces 31 for engaging spring blades 32. The

outer ends of the blades 32 are confined between projections 33 so that the blades operate to counter-balance the weight of the seat section in raising it and to cushion the movement of the section in closing it. Secured to the outer end of each lever 29 is a guide 34 and a projection 35 for engaging a projection 36 on a jointed jackknife link 37 the ends of which are pivoted to the frame 28 and one link having an extending projection 37' for engaging the other and limiting their movement in one direction, and a lever 38 which is pivoted to the seat frame or outer end of the lever 29, the other end of the lever 38 beingpivoted near one end on a pin 38 to the middle bed section 21 and forming the only connection between these two bed sections. The guide rails 34 control the overturning movement of the seat section 16 and the projections 35 prevent the seat section from lunging forward at a certain point in the overturning movement of the seat section.

To operate the legs 26, a bar 39 is pivoted to the free end of each lever 38 at the ends of the middle section 17 and the bar is held in place by a projection 40 at the end of the frame so that the free end of each bar engages the end of a lever 41 pivoted intermediate its ends at 42 to the frame 21 and connected at its other end by a pivot 41' to the upper end of the adjacent leg 26.

In order to hold the seat section in an inclined position, as shown in Fig. 2, a lever 43 is pivoted at one end to each of the levers 38 and has a projection 44 at the other end for engaging the guide rail 13. Intermediate the ends are notches 45 adapted to be engaged by a projection 46 carried by a lever 47 pivoted at one end to the frame 21 and movable into locking engagement with the notches 45 by means of a handle 48 at the free end. The engagement of the projection 46 with the notches 45 prevent the continued unfolding movement of the levers 38 and therefore lock the seat section in any selected inclined position. As the extension of the bed is not complete the outer sections will be inclined, as shown in Fig. 2.

Carried by the seat section is a front board 49 which engages a front cross rail 50 when the bed is closed and may form a head or foot rest when the bed is open. At the outer end of the bed, forming an extension of the frame 24, are projections 51 which carry a cross rail 52, preferably in the form of a handle by means of which the sections may be folded or unfolded.

Secured to the inner end of the seat frame 28 is an angle bar 53 adapted to engage the lower cross rail 12 when the bed sections are folded, as shown in Fig. 1, and to confine and hold the bed sections in place by such engagement. In unfolding the bed the seat section is first raised at its outer end which depresses the inner end, disengaging the bar 53 from the cross piece 12.

This structure is suitably upholstered and covered so that no part of the operating mechanism is visible when the sections are folded, and a fabric cover 54 may even be extended over the rear ..for the storage of bed clothes which is easily accessible by simply lifting up the seat section and even if the compartment is more than full it will only compress the springs of the bed sections to include them.

In operation, assuming the structure to be folded, the loose cushion or cushions 55 are first removed. The seat section is grasped at its outer edge and raised upwardly by means of a fabric strap 56 or any other suitable means which disengages the rail 53 from the cross bar 12, the seat section swinging about the axis of levers 29. This uncovers the handle or cross bar 52 of the outer section which is then grasped and pulled outwardly, moving the outer and middle sections 18 and 17 upon their rollers 27, 22 and 23 which are in engagement with the guide ' rails 13, 14 and 15.

As the bed sections are moved outwardly, the seat section 16 is turned over about levers 38 and. 29, and as they approach the position indicated in Fig. 2, the projection 36 of the jointed link 37 engaging the guide 34 controls the operation of the seat section, first straightening out the jointed link 37 from its partially folded position, as shown in Fig. 1, to its straight line position as shown, in Fig. 2, and causing the gradual lowering" movement of the seat section as the other sections are pulled outwardly, until the levers 29 engage frame limit stops 58.

In the completely extended position shown in Fig. 3 the sections are in horizontal alignment, the projection 36 is in contact with the guide rail 34 and infolding the bed an inward push or slight raising movement at the end of the outer section pulls the upper end of the lever 38 about its pivot, causing the inner end of the seat section 16 to be pulled upwardly about the upper end of the lever 29. The continued inward sliding movement of the middle and outer sections 17 and 18 engages the rollers 22 and 23 of the middle section with the guide rails 13, 14 and 15, and the continued movement of the levers 38 and 29 toward each other rotates the seat section 16 about the end of the lever 29 as controlled by the engagement of the projections 36 with the guide rails 34. When the seat reaches a vertical position, it would tend to flop over forwardly were it not for the engagement of the projections 36 with the projections 35 at the ends of'the levers- 29 which limits and controls the overturning movement of the seat. The rotative movement of the levers 38 about their pivots in folding the sections fold the legs 26, which cause the rollers 27 to engage between the guide rails 13 and 15.

In the inward movement of the sections, the guide rails 13 and 14 incline upwardly at the rear so that when the outer rollers 23 of the middle section reach the space between the lower ends of the guide rails 14 and the guide rail 15, the rollers 23 will drop through the openings and will continue upon the lower guide rails 15 until they reach the stops at the ends of the rails. Likewise the rollers 2'7 at the ends of the legs 26 will drop through the opening following the lower guide rails 15, thereby supporting the middle section in a vertical position at the back of the frame and the outer section below the seat and behind the foot board 49 which is carried by the seat frame and folded downwardly thereover.

In its closed position the resilient portion of the middle bed section 1'7 engages the rear of the upholstered back 11 and presses it outwardly, as clearly shown in Fig. 1, so that the resiliency of the back upholstering is increased by the resiliency of the middle bed section 17 which also causes the back to assume a more bulging position and provide sufiicient space in the back for containing the middle bed section.

To assist the movement of the sliding sections, a pair of rollers 57 may be mounted one at each side of the frame below or at one side of the guide rail to engage the edges of legs 26 and the under sides of the frames 21 and 24 as they are moved into and out of the frame. Near the top of each guide rail 14 is a projection 60 which assists in holding the section 17 in place by the engagement of roller 22 thereover.

Instead of mounting the seat section so that it is inverted at the rear of the other sections, a

seat section 61, as shown in Figs. 5 and 6, may be mounted in a frame 62 so that it swings outwardly upon levers 63 in advance of the sections, the outward movement unfolding a supporting leg 64, and the other sections 65 and 66 being mounted on rollers 6'7, 68, and 69 which engage guide rails '70 and 71. The outward movement of the seat section raises the section 65 by the engagement of levers 63 with fixed stops 72 at the rear of the seat section which extends the connected links ,73 and '74, one having a fixed pivot 75 with the frame at each side thereof and the other having a pivoted connection '76 with the bed section 65 so that in unfolding a leg 77 pivoted at each side of the section '65 is positively unfolded by a link '78 extending between it and one of the connected links 74. A fixed stop 79 in the frame engages the other connected link '73 in one limiting position, and a fixed stop 80 engages the same link in the other limiting position, and the bed section 65' carries a fixed stop 81 which engages the other connected link 74 in the other position to hold the bed sections 65 and 66 uprightly at their joint.

Connecting the sections 65 and 66 is a hinge 82 and when extended this side of the rear bed section is supported by its connection with the middle section 65 and the inner end of the section 66 is supported by its rollers 69 in engagement with the stops at the ends of the guide rails 71.

In the folding movement of this construction, the rear section 66 moves backwardly to an upright position where its upper edge engages and distends an upholstered back 83, the supporting rollers 68 and 69 engaging difierent guide rails and the lower section 65 engaging only the guide rail '70 with its projections 81 and rollers 67. The seat section is supported at its rear side by engagement with the guide rails '71 and at its front by a front board 84 which rests upon lower cross pieces 85.

In another form of the invention as shown in Figs. '7 and 8, the rear and middle sections are similar in construction and operation to those shown in Figs. 5 and 6, but a seat section 90 is mounted for overturning movement by means of links 91 at each side connected at one end to the lower section 65 and at the other end the seat section 90 and having a link 92 for connecting it to a leg 93 pivoted at the upper side of the seat so that when the seat is inverted, as shown in Fig. 8, the leg will swing downwardly therefrom. To permit the overturning movement of the seat 90 a front board 94 is mounted by means of a loose hinge or links 95 so that it will swing about the ends of the seat from the position shown in Fig. '7 to the position shown below the seat in Fig. 8. In this construction the seat section is inverted about the upper end of the levers 91 as a pivot and the sections 65 and 66 are pulled outwardly to unfold the bed as explained in'connection with Figs. 5 and 6. In this form of the invention the seat section is supported by engagement with the guide rail 71 by the side links 91 and by the front board 94 which engages the cross rail 85.

As thus disclosed, the structure of the seat mounting may be varied without materially changing the operation of the other sections which are stored at the back and below the seat and-are drawn outwardly or are uncovered for outward movement by the movement of the seat section. The sections in each case are guided by fixed rails at the sides of the frame and the movementis continuous and automatic when started.

It is obvious that other changes may be made in the construction, operation and arrangement of the parts.
