CONVERTIBLE CHAIR BED.

Application filed April 12, 1927. Serial No. 183,088.

My invention relates to a chair of the type adapted for conversion, by extension of certain parts, to form a bed. i

The principal object of my invention is to provide such a convertible chair which is adapted to be over-stuffed and upholstered to resemble the ordinary typeof over-stuffed arm chair in present day use. A second obj ect is to provide means for converting such a chair into either a reclining chair or a bed. A still further object is to preserve the comfort and appearance of the ordinary arm chair, without interfering with its ready conversion into a comfortable bed. Such an article can be made to match other pieces'of furniture to form a drawing roomset, and can be ordinarily used in the drawing room as a chair. It is of such a size that it can beeasily moved from one room to another, when its use as a bed is desired.

Other objects and advantages of the invention will be apparent from the following specification, which should be read with the understanding that the form, construction, and arrangement of the several parts may be varied, within the limits of the claims hereto appended, without departing fromv the pirit of the-invention as set forth in said arms.

lVith this in View a preferred embodiment of my invention will now be described fully with reference tothe accompanying drawings, wherein Fig. 1 is a perspective view of my convertible chair and bed, indicating in dotted lines the projection of the foot extension frame.

Fig. 8 is a sectional detail, showing the folding of the foot extension on the seat frame.

In the drawings, the reference numeral 1 designates the frame of the seat and base portions of my chair, said frame being preferably made of wood and similar in form and construction to that of the'usual over-stuffed chair, as shown in Figs. land 2. 2 designates, in general, the upholstery, any well known type and. form, and which'is, in general, attached to the frame 1 inthe usual manner. 3 and 8 are the arms,whioh are also framed and upholstered in the usual manner, except that one or both of said arins is mounted upon hinges and adapted to swing outwardly and downwardly in aman'ner to be described later. i

A pair of baranembers 4, preferably angle iron, Fig. 8, are the seat portion ofthe frame 1, Figs. 2 and 8, one at each side thereof, at the base of the arms 3 and3. A second pair of bar members 5 are 'pivotally connected at 5 Figs. 2 and 8, with the forward ends of the fixed bar members 4, and are adapted either to be fold.- ed back bars 4, as shown in Fig. 8, or to be extended permanently mounted uponparallel and adjacent to said-fixed which ma be of forwardly in line therewith, as shown in Fig. I

2. The are rigidly joined by a cross/member 6, to which a pair of legs 7 are pivotally connected. As shown in Fig. 7'said legs are pivoted to the cross bar 6 at 8, and either folded against said cross bar or extended downwardly to form legs or supports therefor, as indicated in dotted lines. When so extended, said legsare slightly inclined outwardly, to providegreater lateral stability, and are provided with shoulders 9 which engage fixed pins 10. both .to limit their swinga the pivots 8 of a Theifolding bars 5 and the end cross member 6 constitute an extension frame, which, when extended with its free end supported by the legs 7, forms as shown in Figs. 1 and 2,.a horizontal continuation of the seat frame are adapted to be forward ends of the folding bars 5 bars 4. A suitable resilient fabric, such as the tinuous, with its forward end connected with the cross member 6, and being adapted to fold back upon itself when the extension frame 5-6 is folded back upon the seat frame, as seen in Fig. 8.

A rear extension frame is formed similarly to the forward extension frame 5-6, having side bars 12 pivoted at 13, Fig. 2 to the rear ends of the fixed bars 4 and a rear cross member 14. This rear extension frame is adapted to swing back horizontally, as shown by the dotted lines in Fig. 2, to form a rearward continuation of the seat frame, and the resilient fabric is continued to its rear cross member 14 as indicated. Thus when the two end frame portions are extended, as shown in Fig. 2, theyform with the fixed center portion virtually a single frame of suitable length to make a bed, and actually support a continuous re silient bed fabric, upon which a suitable mattress, not shown, may be placed.

The rear extension frame 12-14, when swung to a substantially upright position, as shown in Fig. 2, forms the support for the back 15 of the chair, and when lowered to its extended or horizontal position, said back 15 is adapted to be inverted to form a leg or support for said frame, Fig. 2. The back 15 is formed in the usual manner over a wooden or other suitable rigid frame 16, similar in general form to the usual chair back frame, except that it is provided with grooves 17 2 and 5, in its rear surface into which the extension frame 12 14 can fit. connected at 19 with the extension frame members 12 and at 20 with the side members of the back frame 16, and are so positioned that the back 15 can be inverted and swung over the end of the extension frame 12-14, as seen in Fig. 2. When the latter is in its horizontal position, as shown in said Fig. 2, the top of the back 15 rests upon the floor, and said back is tilted under the frame 1214 sufiiciently to cause the end member 14 of the latter to bind securely against said back when weight is applied. This binding prevents the end of the frame 12-14 from dropping, and also prevents the back 15 from slipping out of its supporting position.

In the chair position, as shown in Figs. 2 and 5, the extension frame 1214 lies entirely within the grooves 17 at the back 15. The back or bottom of said extension frame is covered with a piece 21 of the cover material of the chair, which conceals it from view. Said cover piece I is preferably continuous from the rear bottom of the chair, as inFig. 2, its upper end being secured to the extension cross member 14 by being passed around and under a strip 22 suitably secured thereto. The back 15 and extension frame 12 14 are held in the chair position by suitable latches,

preferably swinging notched. members 23,

Fig. 6, pivoted at 24 to the frame members 12, and adapted to engage pins 25 in the rear ends Links 18 are pivotally of the arms 3 and 3'. Suitable retarding springs are provided to partially support the weight of the back 15 and extension frame 1214, so that they will not drop suddenly when the latch-es 23 are released. I prefer to make such springs as flat leaves 26, Fig. 6, having their lower ends secured at 27 to the base frame 1, and their other ends bearing against the side members 12 of the extension frame.

When the device is in the extended or bed position, the arm 3 can be swung outwardly and downwardly, out of the way, as indicated in dotted lines in Fig. 1, to provide more convenient access to the bed. For this purpose I connect said arm 3 with the base frame 1 by hinges 28. A bolt 29, Fig. 4, slidable through the side of the base frame 1, and adapted to enter a socket 30 in the arm 3, holds said arm in its upper position. The lower end of said bolt is provided with a handle 31 by which it may be operated, and it is also provided with a pin 32 travelingin a bayonet slot 33 to hold it in its upper position. The joint between the chair base and the arm 3 is concealed by the continuous outer covering 34. Both arms may, of course, be made to swing if desired. The flat surfaces 35, Fig. 1, when the arm is lowered, can be used as a convenient bed-side stand.

I prefer to provide the seat portion of my chair with additional helical compression springs 36, Figs. 2'and 8, of the usual type, under the wire fabric 11. Such springs reinforce the wire fabric at the region receiving the greatest weight, both as a chair and as a bed, that is, the seat of the chair and the central portion of the bed. The forward edge of the chair seat is also preferably reinforced by a transverse flexible or articulated wire 37, independent of the wire fabric 11 and connected with, the side frame members 4 by tension springs 38, Fig. 3. The covering 39 of the front of the chair base is continued up and over the front edge of the seat, to conceal the fold of the wire fabric 11, and is provided with a welt 40 to serve as a further reinforcement of said front edge, Fig. 8. The end of said covering 39 is secured to the extension frame members 5 by suitable resilient connections, such as strips 41 of elastic material, as shown in Fig. 3, so that the front edge of the seat may give without straining said covering. The endof said covering is also slit, as shown at 42, Fig. 3, and the edges of the slit are joined by an elastic connecting strip 43, for the same purpose.

I provide a removable seat cushion 44, Fig. 1, made in two parts folded together along one end, as shown at 45. Both parts are preferably provided with springs, not shown, after the manner of the well known spring-filled cushions. When the forward extension frame 4-4 is extended, the cushion 44 can be opened out and laid upon the seat and said extension, covering both, and providinga full cushioned reclining or extension chair.

The front and rear of' the base frame 1 are cut away at their upper edges, as shown in front at 47, Fig. 1, to provide clearance for the deflection of the wire fabric 11. The front cut out portion also provides clearance for the deflection of the forward edge of the seat when used as a chair.

It will be seen that my device, when in its chair position, has both the comfort and appearance of the ordinary over-stuffed arm chair, the entire extension mechanism being concealed. To make a reclining chair, the

cushion 44 is removed, the forward extension frame 45 is swung forwardly and its legs 7 extended to rest upon the floor, and said cushion is opened out and replaced. To make a bed, the back and rear extension frame 1214 are let down, said back is swung over the end of said frame to rest upon the floor, the arm 3 is let down, and a suitable mattress, not shown, is placed upon the wire fabric 11. A chair of ordinary size will provide a bed inches wide by six feet or more in length, depending upon the height of the chair back. I
