erally been constructed so that the main frame The main reason for providing for a delay in remains resting upon its own legs when converted the leg-projecting movement while the extension into a bed. In such constructions, a comfortable section isswung through a predetermined initial seat height above the floor level results in a bed movement, is to make it an easy task for the surface whichis rather lower than that of the extension section to be swung up vertically and 55;

thereafter to take advantage of the weight of the pivoted section to exert a leg-projecting effort, such effort being aided, if desired, by the pulling power of springs associated with the legprojection mechanism, as will be apparent from the description of particular constructions which follow. For the same reason, the actuating mechanism is also arranged so that when converting a bed into a chair or settee a predetermined initial swinging movement of the extension section must be made before the retraction of the bed-legs is initiated or effected.

The accompanying drawings, which illustrate various embodiments of the invention, show clearly the comparatively large space provided below the seat of the chair or settee in which the bed-clothing may be loosely accommodated, in addition to flock or other mattress pads which are preferably laced to the bed-supporting surface, this latter being composed of two wire spring-mattresses, one on the main frame and the other on the extension section.

Figures 1 to 8 of the drawings show a construction of bedchair employing jointed bed-legs which are housed in the collapsed condition solely within the main frame, Figure 1 being a pictorial view of the chair showing how closely it resembles in appearance an ordinary upholstered armchair, whilst Figure 2 shows the extended bed (Without flock mattresses or bed-clothing) and illustrates the natural bed-like appearance which the article presents. Figure 3 is a part-sectional side View of the article in chair form. Figures 4 and 5 are part-sectional fragmentary front views, the sections being taken on lines IVIV; V--V respectively of Figure 3. Figure 6 is a longitudinal section of the article in bed-form. Figure '7 a fragmentary sectional plan on line VII- III of Figure 6 and Figure 8 is a sectional view of one of the erected jointed bed-legs to an enlarged scale.

Figure 9 is a detail vertical sectional view taken on the line Q-9 of Figure 8.

In the construction of bedchair illustrated in Figures 1 to 8, the same comprises a chair base designated generally as A and a seat unit B, the base A includes a main frame which normally rests upon the floor and has four jointed collapsible legs associated therewith, said legs being hereinafter referred to as bed-legs, and which are housed in a pair of side members in the form of boxes or housings 2 having open bottoms 3. A wire mattress support l extends between side members or boxes 2 and an upright member 5 forms the head board of the bed when the article has been converted into bedform. The seat unit or extension section B comprises a pair of upholstered arms 5, an upholstered back 1, and a wire mattress support 8 having an upholstered seat 9 at its upper side. Said support 8 extends transversely between a pair of closed-in side boxes it which latter extend vertically above and below the level of the mattress 8, the upper parts of said boxes ll) being enclosed within the upholstered arms 5. In this construction the boxes Ill serve only to house the auxiliary front-end legs used when the chair is extended to bed-form. The use of these auxiliary legs is optional and if not required there is no necessity to employ the boxes ill, any other suitable side members being then provided.

The chair base or main frame A and the seat unit or extension section B are connected together solely by means of a pair of hinge bars ll,

one at each side of the chair, said bars ll being hinged to the boxes 2 of the mainframe A at pivots I2, and to the boxes ll) of the extension section B at pivots l3.

The wire mattress 5 of the main frame A is resiliently mounted for use as bed-supporting surface by being suspended on tension springs M anchored to housings l5 and secured to the walls of the boxes 2. Similarly, in order that the wire mattress 8 of the extension section B shall yield when the seat 9 is sat on, rods 16 are provided which rest upon compression springs l'l carried in housings l8 secured to the walls of the boxes Hi. When the section B is swung over to form a bed extension, the mattress 8 also yields to any weight imposed thereon by reason of the rods [6 then bearing down upon the compression springs Ii) carried in housings 20 also secured to the walls of the boxes l5.

The collapsed bed-legs 2| and the leg-projecting mechanism associated therewith are housed in each of the open-bottom main-frame boxes 2, each leg consisting of a pair of tubes 2la2lb forming upper and lower sections connected together by a pivoted knee joint 22, the upper tube 2m being anchored by a pivot connection 23 to the roof 24 of the box 2 whilst the lower tube 2H2 is anchored by a pivot 25 to a longitudinal hollow connecting bar. 26 which joins the two legs on one side of the chair together and has knobs 2? for supporting the bar 26 above floor level. In order to ensure equal collapsing and erecting movement of the bed-legs, worm sectors 2lc are secured to the bottom sections of the half-legs 2H) which co-operate with a spindle 26a rotatably mounted within the hollow bar 26, the opposite ends of the spindle 26a having worm threads or pinions 2% adapted to mesh with the sectors 2lc. Transverse connection bars 28 join together the two side bars 26 on opposite sides of the frame which constitutes the base of the chair which rests on the floor. Within each tubular leg section 2la2lb is housed a tension spring 29, anchored at the knee-joint end thereof to a plug 35 and at the opposite end to an anchorage pin 3i which is eccentrically disposed in relation to the axis of swinging of the halfleg 2la2lb about the pivot 24 or 25 respectively that the springs 29 function to assist the legs in moving from the collapsed to the extended position. The leg-operating mechanism consists of a system of pivoted linkage comprising a main link 32 pivoted to the lower end of the hinge bar H and to a straight lever 33 pivotally anchored at 35, a connecting link 35 extending between the lever 33 at the cranked lever 36 which is pivotally anchored at 31. From the levers 33 and 36 outwardly extend in opposite directions links 3839 respectively which arev connected to the upper parts of the upper halflegs 2 la. It will be apparent from Figures 3 and 6 that when the hinge bars H swing about pivots l2, the linkage operates to erect the collapsed legs, the leg springs 29 assisting in the action. It will also be quite clear from. the drawings that during .the initial swing-over movement of the extension section B, said section swings about the pivots I3, without moving the hinge bars II. When the section B reaches the position indicated in chain-dotted lines in Figure 3, the floors lil of the boxes l5 abut against the hitherto stationary hinge bars l i so that during the continued swinging movement of the section B, said bars ll move with the section and thus actuate the leg-projecting mechanism. In other words, the 7 axis of swinging of section 'B is transferred from pivots E3 to pivots I2.

During the initial swing-over movement of extension section B about pivots I3, the links 4! swing idly about the upper ends of the stationary hinge bars ll without imparting much swinging movement to the spring-controlled cranked levers 42, so that the front-end legs 43 which slide Within tubular housings 44 in the chair back 'i are not projected beyond the top of said back I. When the section B and hinge bars H swing about pivots i2, however, the links 4| and levers 42 operate to project the front-end legs 43 to the position shown in Figure 6.

It will be observed that ample space for the storage of flock mattresses (which are preferably laced to the wire mattresses 4, 8) and of all the necessary bedclothes is afforded in the chair within the space between the wire mattresses 4, 8. Figure 9 illustrates clearly the extent'to which the extension section B can be swung over before the leg-projecting movements are effected, whilst Figure 10 shows how, after the predetermined initial swing-over movement has been effected,

.the continued swinging of the section B is accompanied by the projection of the bed-legs. The opening at the front of the chair between the wire mattresses 4 and 8 is normally covered by a flexible curtain 45.
