As shown on the drawings:

The improved collapsible and convertible article of furniture embodying this invention is of the combination bed and chair type, normally adapted when not in use to be carried in collapsed form within a suit case or carrier along with other articles of collapsible furniture, such as chairs, as illustrated in Figure 2, which discloses a convertible type of suit case or carrier consisting of two integrally connected sections I and 2. The suit ease or carrier is of the convertible type, whereby the suit case may be opened up and used as a table or the like of the type illustrated and claimed in my co-pending application for patent entitled Table and carrying case, filed on even date herewith, Serial No. 238,998.

Each of the case or carrier sections I and 2 has mounted therein a pair of collapsible legs 3 which are normally folded within the case sections l and 2, as illustrated in Figure 2. The collapsible and portable type of combination bed and chair embodying the present invention is normally adapted to be collapsed in compact separate sections, as illustrated in Figures 4 and 8, permitting the same to be placed side by side in collapsed form within a section of the suit case, as illustrated in Figure 2, to occupy a comparatively small amount of space, to permit the bed to be stored away when not in use and also permitting the collapsed bed to be transported.

The improved combination bed and chair consists of two units adapted when in collapsed form to be entirely separated from one another and furthermore adapted to be interlocked with one another to form a joint article of collapsible furniture. The base or supporting unit of the article of furniture comprises a pair of side rails or bars 4 constructed of wood or other suitable material. Each of the side rails 4 has secured on each end thereof, by means of a screw 5 or the like, a metal end casting comprising a side or outer wall 6, a top flange 1, a bottom flange 8, and an end wall 9. Integrally formed on the outer face of the lower corner of the side plate 6 on each of the castings is a leg stop or abutment lug I0. The side wall 6 on each of the castings is provided with a leg bolt opening and a leg bolt slot I I. The bottom flange 8 of each of the castings is provided with a guide slot I2 (Figure 6) Also provided on the side wall 6 of each of the castings is an inverted T-slot I3 (Figure 3), the shank end of which projects upwardly and opens through the top flange 'I to communicate with a slot or notch I4.

Provided in the top and bottom anges 'I and 8 of each of the corner castings of the base unit are bolt openings. Integrally formed on the inner surface of each of the casting top flanges 'I is a boss I5, positioned to project into a recess or notch provided on the top surface near each end of the side rails 4 to assist in preventing the side rails from being pulled out of the corner castings.

Integrally supported against the outer face of the side plate 6 of each of the corner castings by means of a supporting bolt I6, is a base leg I'I, which when in vertically supporting position contacts the stop I0 to limit the swing of the leg. To prevent the leg I1 from swinging back to a closed position away from the stop I0, each of the corner castings has slidably engaged therein a transversely projecting lock bolt I8 adapted to slide outwardly through the slot Il. Integrally formed on the bottom edge of each of the locking bolts I8 is a downwardly projecting extension or nger I 9 which projects downwardly through the guide slot I2 in the bottom flange 8, thereby providing an arrangement for limiting the shifting of the lock bolt I 8. To assist in holding the lock. bolt in position, a spring-controlled pin or stud 2) is mountedin each end of the side rails 4 (as clearly illustrated in Figure 7). When the lock bolt I8 is projected outwardly, as illustrated in Figure 6, a base leg I I is engaged between the stop I0 and the bolt I8 to prevent pivotal swinging of the leg in either direction.

Engaged through the bolt openings of the corner casting top and bottom flanges TI and 8 respectively is a bolt 2l. Pivotally supported on each of the bolts 2l within the corner casting is one end of an end brace rail or transverse member 22 constructed of wood or other suitable material. The opposite end of each of the transverse or end brace rails 22 is pivotally connected by means of a hinge 23 to the inner end of another end brace rail or member 22, the outer end of which is pivotally connected by means of a bolt 2l to an opposite corner casting. The two hingedly connected transverse brace rails 22 are arranged in pairs at each end of the base unit and form transverse braces for holding the side rails properly spaced apart when the base unit is set up, as illustrated in Figure 5.

For the purpose of preventing the hingedly connected transverse braces 22 from accidentally collapsing, each of the brace rails 22 is provided with a recess 24 in which a gravity controlled latch bar 25 is pivotally supported at one end by means of a pivot pin or bolt 26, as illustarted in Figure 7. The opposite end of the pivoted latch bar or bolt 25 has one corner thereof notched as at 2l, forming a contact or stop pin 28 adapted to drop into contact with the inner face of the bottom flange 8 of a corner casting when the brace rail 22 is in bracing position at substantially right angles to the side rail 4. The notch 2'I in the latch bolt 25 permits the latch bolt to drop over the inner edge of the flange 8 to position the latch bolt 25 in an inclined position, as shown in Figure '7, to act as a brace preventing the accidental collapsing of the hingedly connected brace rails 22.

To brace the lower end of the leg II against spreading outwardly away from the side of the base section when the same is set up for use, the lower endsA of the two legs at each end of the base unit are connected by means of a flexible brace strap 29 constructed of leather, canvas, belting or other suitable material and having the ends thereof bent around the lower portions of the legs l'I and secured thereto by means of nails or other suitable fastening devices. It will thus be seen that the combination article of furniture includes a base or supporting unit, as illustrated in Figures 4 to 7, inclusive, adapted normally to be collapsed and folded into a compact form, as illustrated in Figure 4, to store the same in a comparatively small amount of space or to pack the same into a suit case, as illustrated in Figure 2. The base unit may be readily opened up for use by rst swinging the supporting legs I'I downwardly from the positions illustrated in Figure 4 at right angles to the side rails 4 and against the stop members I0, after which the shiftable latch bolts I8 are moved from the dotted linepositions shown in Figure`6 into thewfull `line positions, to hold the supporting legs l1 properly braced against accidental collapsing.

After the legs l1 have been dropped into supporting position, the two side rails 4 are moved apart to their full amount, thereby causing the hingedly connected transverse brace rails 22 to swing to the full line positions illustrated in Figure, so that the two brace rails 22 at each end of the base unit are in substantial alignnient with one another. In the open position of the two transverse brace rails, the gravity-controlled latch bolts or bars 25 are adapted to drop downwardly into the full line position illustrated in Figure '1 to engage the bottom flanges 3 of the respective corner castings to hold the .hingedly connected transverse brace rails 22 against accidental collapsing. With the transverse brace rails in extended position, as illustrated in Figure 5, the ilexible brace straps 29 are opened up into full position for use and are held stretched across the iront and rear ends of the 4base unit to brace the lower portions of the legs complete the assemblage.

Referring now to Figures 8 to 12, inclusive, which illustrate in detail the various features of the top or bed section, consisting of a mattress unit constructed oi a strip oi canvas or other similar strong material. The mattress strip comprises a wide middle or intermediate main or seat section 3U, a head or chair back section 3l, and a foot or leg `section 32 which is narrower than the head section 3l. The head section 3l is slightly narrower than the middle Section 3u, as clearly illustrated in Figure 10. The outer end of the head section 3l of the mattress unit is provided with a suitable hem at 33, leaving an end loop 34 for removably receiving a head dowel rod or bar 35, the ends of which project beyond the sides of the loop 34 for engagement in side frame members, as hereinafter .more fully described. The outer end of the mattress root section 32 is also provided with a hem 33, forming a loop portion 34 for removably receiving a foot dowel rod or bar 3E, the ends oi which project for engagement in the side frame members, as hereinafter more fully described.

Disposed longitudinally along each of the side margins of the mattress strip are side frame units, each comprising an intermediate rail 31 constructed of wood or other suitable material, the outer side of which is provided with a lon- `gitudinal groove 33 (Figure 3) for the reception of a clamping strip 39 for securely holding the side margin of the mattress center section 3u clamped in the groove 38. The clamping strip 3e is held in position by means of screws fit1 or other suitable devices. For the purpose of mounting the mattress unit upon the base supporting unit ofthe device, each of the intermediate side irame rail members 31 has engaged in the lower surface at each end thereof an attaching bolt 4i having a washer 42 engaged thereon. Secured on the inner side of the head end of each of theframe rails 31 is a stop or spacing block Pivoted to the head end of each of the side frame intermediate rails 31, by means of a wing bolt 44, is the inner end of aside frame head rail 45 provided with a dowel receiving opening 46 near the outer end` of the inner side thereof. l i

Pvotally supported on the outer surface near `one end of each of the head side rails 45 `is the upper end of a. head leg 41 constructed of metal or other suitable material. Rigidly secured on the outer surface of each of the head rails 45, near one end and adjacent the lower edge of the head rail, is a sto-p member or block 48 for limiting the swing of the leg 41 when the same is swung downwardly to a supporting position for use, as illustrated in Figures l. and 2, To prevent accidental collapsing of the legs 41, a

`spring-controlled stud or pin 49 (Figure 12) is` mounted in the head rail 45 to project from the inner side thereof to engage the side of. a leg 41 opposite the stop block 43. To swing the leg 41 into a closed position adjacent the head rail 45, it is only necessary to depress the spring-controlled pin 49.

Rigidly secured to the inner face of the `foot end of each oi the intermediate side frame rails 31 is a spacing block 5t. Pivotally supported on the spacing block 5u, by means of a wing bolt 5l, is the inner end of a side frame foot rail 52 constructed of wood or other suitable material. The inner face of the outer end of the side frame foot rail 52 is provided with a recess or opening 53 for removably receiving one end ofA the foot dowel bar Zit. Pivotally supported at one end on the inner side of each of the frame ioot rails 52 is `one end of a foot leg 54, the swing of which is limited by means of a stop block or stop nut 55. To prevent accidental collapsing of the foot leg 54, each oi the foot rail frame members 52 is provided with a spring controlled detent or pin 49 similar in construction to that illustrated in Figure 12.

For the purpose of securing the side margins of the head and foot mattress sections 3| and 32 respectively to the respective side frame head rails 45 and foot rails 52, the side margins of the mattressrhead and foot sections are provided with oval fastener eyelets 5G for the removable reception of oval curtain fasteners 51 secured upon the top surfaces of the side frame rails 45 and 52, as illustrated in Figure 9.

Whenthe combination bed and chairis not in use,the base section is adapted to be collapsed, as illustrated in Figure 4, and the bed or mattress section is adapted to be collapsed, as illustrated in Figure 8, so that both of the collapsed sections maybe placed side by side within a suitcase section 2, as illustrated in Figure 2. The opposite half of the suitcase, namely, the Section l is adapted to have removably engaged therein a folding and collapsing chair 58 of the type illustrated in my co-pending application for patent entitled Chain iiled of even date herewith, Serial No. 238,99'1.- Several of the collapsed chairs 58 may be carried in the suitcase section i, if desired.

From the assemblage illustrated in Figure 2, it will be noted that a convenient furniture combinationV is provided in the collapsible sectional combination bed and chair and the collapsible and folding type oi chairs which may be conveniently stored and transported in a combination suitcase and table to provide a very convenient camping or beach outt.

To set up the combination bed and chair into the assembled relationship ready for use, as illustrated in Figure l, the base unit, illustrated in collapsed form in Figure 4, is iirst opened up by dropping the legs I1 into a vertical position and projecting the latch bolts i8 from the dotted line position illustrated in Figure 6 into the full line position to prevent the base legs from accidentally collapsing. The side rails 4 are now separated, thereby opening up the transverse hingedly connected brace rails 22 and simultaneously stretching the brace straps 29. With the brace rails 22 in extended position, as illustrated in Figure 5, the latch bolts 25 fall into position by the action of gravity, as illustrated in Figure 7, to prevent accidental collapsing of the hingedly connected trans'- verse brace rails 22.

The collapsed mattress or top section is now partly opened up and placed upon the base section by engaging the attaching bolts ll and the washer d2 in the T-slots I3 and top slots I4 provided in the metal corner castings of the base section. With the middle portion of the top or mattress unit engaged to the base unit, the mattress side frame, head rails i5 and foot rails 52 are swung outwardly from the full line positions illustrated in Figure 9 into the dotted line positions, and the end legs 4l and 52 are swung downwardly into the full line positions illustrated in Figure 1 to complete the opening up of the mattress frame section. The mattress end sections 3l and 32 are now opened up and the dowel rod 35 is engaged to the loop portion Sli of the mattress head section 3i, while the dowel bar 36 is engaged to the loop portion 34 of the mattress foot section 32. The ends of the dowels are engaged in the recesses provided in the side frame rails 45 and 52, thereby transversely stretching the mattress strip within the set up mattress frame. rIl'le bed is now in a position for use, as illustrated in full lines in Figure 1.

For the purpose of converting the bed sections into a camp or deck chair or the like, it is only necessary to swing the head section upwardly into the dotted line position shown in Figure 1, allowing the head section legs 4l to have the lower ends thereof engaged behind a stop bead or flange 59 integrally formed on the top of each of the front corner castings', as illustrated in Figure 3. rIAhe head legs il therefore act as braces to hold the front section in an inclined position to serve as the back of a chair. The foot section is now swung downwardly from the full line position illustrated in Figure 1 into the dotted line position to provide a leg rest. The intermediate section 3D of the mattress strip now serves as the seat portion of the chair construction.

It will, of course, be understood that many details of construction may be varied through a wide range without departing from the principles of the invention, and it is therefore not the purpose to limit the patent granted hereon otherwise than necessitated by the scope of the appended claims.
