Application led July 1,

To all 'whom t may concern.:

Be it known that I, RUDOLPH Coornn- SMITH, a citizen of the United States, and resident of the city of Montreal, in the Province -of Quebec and Dominion of Canada, have invented certain new and useful lmprovements in Divanettes, of which the following is a full, clear, and exact description. v

This invention relates to improvements in divanettes, and the object of the invention is to provide an article of furniture which may be arranged as a divan or seat in the daytime and transformed into a bed at night.

A further object is to provide a device of -this character which will ,accommodate a mattress of standard thickness, thus providing a. more comfortable bed.

' A still urther'object is to provide a device which may be converted from one form to the other with very little exertion.

Another object is to provide a device in which the bed andseat construction is supported directly on the floor and no t on the ends of the divanette.

The device consists briefly of a framework supported by casters or the like from the floor and carrying a folding bed bottom and a seat linked up to the bedy bottom so as to move automatically into and out of position. The divanette ends are mounted upon the frame and are connected by .a back member carrying a movably mounted divanette back.

In the drawings which illustrate theinvention;-

Fig. 1 is an end elevation of the device in folded position, one end being removedv to expose the mechanism. j

Fig. 2 isa view similar to Figure 1 extended to bed form. i

Fig. 3 is a partial section on the line 3-3, Figure 1.

Fig. 4 is an elevation of the centre ,connection of the bed. y'

Referring more' particularly to the drawings, 11 designates a frame of suitable construction supported by means of casters 12 or the like on the floor and provided at each front corner with a short upright 13 supported by a brace 14. The frame 11 may be stiffened by braces 15 and the uprights connected toward their upper ends by a cross member 16. A Jfront foot-board 17 is carmaar Parent orricn.

ried by the front frame member 11 and a cross member 16 and extends froml end to end of the device. Seat ends 18 of any suitable construction are provided for the divanette or seat and are. each provided toward the front vertical edge with an inwardly projecting bracket 19 carrying a suitable number of bullet-pointed pins 20 adapted to engage in the upright 13. At the lower back corner each end is provided with a bracket 21 adapted to be bolted to the frame 11.- Each end is thus supported by the frame 11. The ends are connected and held a'gainst possible swaying by a seat back 22 provided -metal disposed adjacent the ends. At each end of the device, an approximately U- shaped arm 26 is pivotally connected at one,

end to a bracket 25 and at its opposite end vis rigidly connected to a back cushion 27. The l -shape of the members 26 enables them to clear the top-board 24, so that the cushion 27 may be swung up to the position shown in Figure 2. One at least of the members 26 carries a latchl 28 pivoted near its upper end and notched at 29 at its lower end to co-operate with a catch 30 on the bracket 25 when the cushion is in its elevated position, as clearly shown in Figure 2. It will thus be seen that the only load on the ends 18 is their own weight and the weight of the back 22 and cushion 27.

The bedbottom is formed of four sections31, 32, 33 and 34 pivotally connected one to the other. The section 31, which ma be termed the centre connection, is at eac side of the. bed a rigid T-shaped structure comprising a head 35 and a stem 36 pivoted near its lower end at 37 to the upper end of an upright 13.

The head and stem are'held rigidly with respect to one another by a diagonal brace 38. The sections 32 and 33 comprise, at each side of the bed, members 39 L-shaped in cross section and pivoted adjacent their ends to the extremities of the head member 35. The extremities of the members 39 each embrace thehead member 35 and the movement of these members relative to the head is thereby limited, so that the members will swing upwardly relative to the head lmember but cannot swing downwardly past the horizontal position, as be clearly seen in Figure 2. The sectioit`34 comprises, on each side of the bed, members similar to the members 39 and connected inside the members 39 of the section 33, so that `the section 34 may swin ,downward from the `horizontal position re atively to the members pending from the section 33. The remote ends of the sections 32 and 34 are connected across the bed by members 44 and 45. Any suitable type of bed bottom fabric 46 is stretched in the frame formed by the sections 31, 32, 33 and 34 and is preferably one continuous fabric from side to side and end to end of the bed bottom. The head section 32 is provided with a rigid head frame 47 of any suitable construction. having a cross bar 48 at the top terminating in upwardly proliectng lugs 49. A folding foot rail 50 of any suitable type issecured to the free extremity of the lsection 34. The length of the centre section between the points of attachment tothe adjoining sections is approximately double the thickness of the mattress which it is intended to use. and the lengt-n of the section 33 between its points of attachment to adjoining sections is slightly less than the length of the section 32 between its point of attachment to the section 31 and the Vhead frame, so that the section 33 may be folded upon the section 32. The section 33 is provided at each side adjacent its connection to the section 34 with a lug 51, adapted to rest upon the to-p rail 48` of the head frame and to be retained by the upturned lug 49.

In order to support the bed bottom in the extended position shown in Figure 2, certain instrumentalities are provided conly ofthe device will be described, as both sides are exactly similar. A link 52 is pivotally connected at one end to the frame 11 and at the other end has pivotal and sliding. connection in a slotted bracket 53 secured under the free extremity of the section 32. A link 54 is pivotally connected at one ena to the stem 36 of the centre connection abouJ midway between'the head and the pivot 37. This link has sliding and pivotal connection at its opposite extremity with the link 52. These members support and control-the movement of the section 32. A cross arm 55 is rigidly connected to the stem 36'on the oppositeside of the pivot 37 from the head 31 and is supported by a bracket 56. The i extremity of this cross arm adjacent the bedV foot is pivotally connected to a bracket 57 secured to the under side of a seat frame 58 adjacent the front edge thereof. A short leg 59f is connected to the rear corner of the seat frame and is provided-with a supporting. member 60. This leg is'adap'ted to extend to the loor and support the rear edge of the seat frame in the position shown in Figure 2, the front edge being supported ultimately by the frame 11. A short .link 61 is pivotally connected between the seat frame 58 and the bed bottom section 33 as close as `possible to its footward end, thus virtually supporting the footward end of the section 33 and the headward end of the section 34. A link 62 is connected between the rear edge of the seat frame 58 at a point on the bed bottom section 34 toward the foot. It will thus be seen that, each of the sections 32, 33 and 34 is provided with a double support, while the section 31 is supporteddirectly by the rigid frame. The headward extremity of the cross arm 55 is connected to one end of a spring 63, the opposite extremity of which is connected to the frame 11, the spring serving to' assist both in the opening and closing of the bed. A seat cushion 64 is mounted on the frame 58, which also carries at its rear edge a suitable'number of stops 65 for the lower edge of the back cushion 27.

Assuming the device to be in the folded seat forming positionshown in Figure 1, it may be converted to a bedV by first pulling forwardly and upwardly on the lower edge of theback cushion 27 until the cushion swings to the position Shown in Figure 2, where it is held by the latch 28 engaging the catch 30. The operator then grasps the foot cross rail of the bed, thus exposed immediately under the-top-board 24, and pulls forwardly and upwardly on the same. The spring `63 at each side supplements this pull and swings the centre connection 31 from the position shown in Figure 1 to the position shown in Figure 2, so that the section i 33 is carried upwardly and outwardly and operating wlth the centre connection 31. For convenience, the arrangement at one side,

eventually vinverted'to occupy the position shown in Figure 2. Toward the latter part of this movement the spring reaches its maximum contraction and during further movement tends to resist a sudden straightening into line of the sections 33 and 34 and a sudden ldropping of the seat cushion 64. As the section 33 pivots' around the section 31 and the section34 pivots around the section 33, a combined action is exerted on the seat frame 58,.moving it away from the section 33 upon which -it previously rested until if occupies Vthe positionshown in Figure 2.

Asl thejccntre connection 31 swings up, it

raises lonen-end of the ,section 32 and also lll draws up the link 54, which operates the link 52 to raise the head end of the sectlon.

To convert the device from a bed to a seat, the foot cross `member 45 -is raised. The sections 34 and 33 remain relatively rigid for a time and the two swing u from the centre connection 31. Early in t is upward swmg, tension is exerted through the link 62 and seat frame 58 on the cross arm 55, so that the centre connection 31 gradually swmgs down toward the position shown in Flgure 1, thus lowering the footward end of the section 32 and allowing the links 52 to' lower the headend of the section. This movement is at irst assisted by the sprin 63. When the movement is partially complete, the tension in the seat frame 58 and 'nk 62. is .increased owing to the seat frame swmgmg about an entirely different centre from the section 33, and at the same time a strong thrust is exerted through the link ,61, so that the sections 33 and 34 swing relatively to one another, the section 33 folding down over the section 32 and the section 34 assuming a vertical position against the back 22.v

As the centre connection 31 swings to the' position shown in Figure 1, the footward extremity of the arm 55 swings up thus raising the front edge of the seat frame into position. The 'relative movement of the sections 33 and 34 acts through the links to force the seat forward relatively to the section 33 until it assumes a slightly inclined position, resting at its rear edge upon the down folded section 33 and passing 1n front of the cross bar 42.` The brackets 53 of the section 32 eventually come to rest on the frame 11 and the lugs v51 of the section 33 come to rest on the cross bar 48 of the head frame, so that a rigid support is obtained for the rear edge of the seat. The back cushion 27 is now Vsupported with one hand and slightly raised so that the latch28 may be disengaged from the catch 30 and the cushion lowered into a osition of rest against the stops earned by the seat frame. If it is desired, the back cushion '27 may be lowered, while the device is arranged as a bed, and will'come to rest on the mattress forming a conveniently inclined back rest or head rest.

The feature of hanging the ends 18 and back 22 on the bed frame in place of hanging the bed frame between the .ends is a point of very considerable importance. The bed is supported directly on the Hoor, and constant operation of the device will never have the effect of loosening the connection between the bed and the lounge ends and causing the device when arranged as a dvanette or seat to be loose in the joints and wabbly. The arrangement also presents a very considerable advantage to both dealers and customers in assembling the structure after transportation or storage. The bed ried out.

proper is a unit in itself and the back carrying the cushion 27 and the ends 13 may be removed without affecting the bed -1n any particular. The device is shipped and stored in this knock-down condition and when assembly is desired, it is only necessary to slip the pins 20 of the ends into the frame members 13 and bolt the brackets 21 innplace. This operation is extremely simple, owing to the fact that the bed frame is self-supporting and does not require blocking up or holding in proper position for connection with the ends. When the ends are in place the back is slipped between them and secured by means of the lu s 23. The operations of extending and folding up the bed require no skill on the part of the operator as the seat and springs 63 virtually direct the movement, so that it cannot be improperly car- The distribution. of wei ht, combined with the assistance rendere oy the springs, is such that very little more than an initiating movement is required to operate the device. The provision of the wide centre connection 31 between the bed bottom sections .32 `and 31 rovides sufficient room for the. doubling o a full thickness mattress. l
