Patented Feb. 4, 1930 UNITED STATES 1 JOHN W. STERBENZ, LOS ANGELES, CALIFORNIA CHAIR BED Application filed June 30,

This invention relates to convertible furniture adapted to form either a bed or a chair, and it is the object of the invention to provide-an article of furniture which when the bed is'not in use will present exactly .the appearance of a usual upholstered chair but which is adapted for convenient conversion to position the bed ready for use, the invention being particularly applicable and hereinafter 1 described with reference to a combined chair and single-width bed although the same construction might readily be incorporated in a structure adapted to form a convertible davenport and a double-width bed, and it therefore being understood that reference to achair is meant to include any article of furniture such as a chair, davenport, etc. forming a seating medium.

= One feature of the invention is the orovision of a bedstead which may be foldedwithin the chair frame or may be extended to form a full-length bed, the folding arrangement providing for concealment of the bedstead, mattress and bedclothes entirely Within the chair frame without in any way distorting its usualappearanoe, with a portion of the mattress'forming the seat cushion so as to simulate exactly the appearance" of a usual chair structure.-

A further feature of the invention is the mounting ofthe' bedstead in a chair frame which is adapted for swinging movement of its arms so that when the bed is to be used the chair arms may be-swung outwardly to permit unobstructed use of the full width of the bed, and also permitting the chair arms to be swung toward one another and locked in normal position when the bed is folded so as to form a rigid chair structure completely concealing the bed and retaining it in inoperative position.

A still further feature of the invention is the simplified arrangement whereby sections of the bedstead may be folded upon one another and securely held in folded position when concealed in the chair frame or may be readily extended and suitably'supported in braced relation 'to formv a sturdy and rigid bedstead. All these andfurther features of the in- 1927. Serial No. 202,603.

vention will be readily understood from the following description of the aocompanyin drawings showing a preferred embodiment 0 the invention and in which:

Fig. 1 is a front elevation of the construction partly in transverse section, showing the bedstead in posit-ion for use.

ing the bedstead folded for use of the structure as a chair.

Fig. 5 is a detail section on the line 55 of Fig. 4.

Fig. 6 is a detail elevation of one of the supporting legs for the bedstead.

Fig. 7 is a detail section on the line 7 7 of Fig. 4.

The chair structure cooperating with the folding bedstead to form a convertible article of furniture may comprise a usual upholstered type of chair having back 1 and side arms 2, and the bedstead is fixed at one end to back 1 and is adapted for folding of its various sections upon one another between side arms 2 so as to form the seat of the chair, or the sections of the bedstead may be extended one beyond another to form a full-length bed projecting forwardly from back 1.

The side arms 2 are hinged to back 1 as shown at 3 so that when the bed is to be extended the side arms may be swung outwardly as shown in Figs. 1 and 3 to permit convenient access to the entire length of the bed, and when the bedstead is folded between the side arms the latter are swung toward one another to'normal position projecting substantially at right angles from back 1 and are locked in such position supporting the folded bedstead, preferably by means of a transverse panel 4 which may be suitably upholstered and which detachably connects the front ends of the side arms at their lower portions so as to conceal the folded bedstead in its seat forming position and present the appearance of the usual spring-cushioned seat portion of a chair.

Fig. 4 is a view similar to Fig. 2 but show- The bedstead is a usual rectangular structure adapted to form a full-length, singlewidth bed as shown in Fig. 3, and is preferably constructed of angle-lronwith its transverse head bar 6 bolted at 7 to the back 1 just below the usual seat level of the chair where the back is rearwardly recessed by termination of the .usual cushioned backing 8; The side bars of the bedstead comprise hin ed' sections adapted for folding upon one anot er so that the folded bedstead terminates short of the front ends of side arms 2 as shown I in Fig. 4, and in the present instance the desired restricted length of the folded bedstead is obtained byforming its side bars of hinged at their respective ends to

sections

10 and 12 form an intermediate section of the bed. A suitable bedspring structure is supported in the rectangular bedstead and is of a type permitting it to readily fold when the sections of the bed are folded upon one another,

and for this purpose the spring structure may comprise crossed supporting wires or thelikeshown at 15, preferably resiliently connected at their ends to the angle-irons forming the bedstead, as for example by coil springs 16, thereby providing a usual comforta-ble spring frame for the bed.

Angle-ironsll and 12 may be hinged at their vertical webs as shown at 20 so as to fold one within another as shown in Fig. 4'

and thereby permit the spring frame to follow the fold without being stretched, but the angle-irons 10-11are preferably hinged at vertical extensions 21 -22 of their vertical webs so that the folded sections 11l2 overlie the section 10 as shown in Fig. 4, and to permit the spring frame to follow this last fold without being stretched the hinge connections for extensions 21-22 are preferably pin and slot connections 23 permitting limited longitudinally shifting of folded sec, tions 1112 relative to section 10.

The sections of the bedstead when in operative position are supported by suitable legs 25 which are adaptedto fold alongside the frame of the bedstead when the latter is folded, the said legs being shown as pivoted to the forward ends of angle-

irons

10 and 11 and to .the end portions of angle-iron 13' so as to provide a rigid support for the bedstead, with the legs preferably releasably held in operative position by braces 26 which are pivoted at one end to the respective angle-irons 10, 1 -and'13 as shown at 27, and which are provided at their opposite ends with quickreleasable means show-n. aspin and slot connections 28 for detachably engaging the corresponding legs sothat by manually releasimmu 'ing the said connections both'the ,le

and

their braces may be folded alongsig e the angle-irons.

- The bedstead is preferably transversely braced when in operative position to insure a rigid constructlon, and for this purpose braces may be provided at the forwardends of sections 10 and ll wherethey will cooperate with the end braces formed-by the head and

foot'bars

6 and 13 to rigidly brace the entire frame. The braces are shown as rods 30 having offset crank ends 31 journaled in bearings 32 on the horizontal webs of the forward ends of angle-

irons

10 and 11, the crank ends being, turned in their bearings so as to space the transverse rods 30 below the spring structureof the bed when the latter is in operative position, sothat" the transverse rods will brace-the bedstead but will not hinder the usual sagging of the.

springs to conform to the weight placed thereon. v a

The bedstead is preferably of somewhat greater width than the chair back 1 so as to permit the bed being of standard width for a single-bed without distorting the usual proportions of the chair, andthe side arms 2 are recessed at their inner sides as shown at 40 for reception of this excess width of the bed when the latter is folded, with said re-., cesses preferably terminating short of the forward ends of the arms as shown at 41- so that when the chair is in use the non-recessed; forward ends of the arms present the appearance of a usual chair structure and lie/in front ofthe' excess width of the folded bed. The forward end of thefolded bedmay be v ioo supported by side arms 2, and forthis pur pose suitable shoulders 45 are provided at, the forward ends of recesses-.40; so that the forward ends of angle irons lO areadaptedv to rest thereon.

The panel 4 which locks side arms 2' i chair to the usual seat level and thereby'cooperates with the forward ends of side arms 2 to completely conceal the folded bed. Th1

the panel in proper position, and the panel closed position extends from thebaseof the may be releasa'bly locked in operative posivtion by suitableconcealedbutaccessible locking means shown as hooks 55 longitudinally projectable and retractable beyond the ends of the inner face of the panel and adapted to engage cooperating eyes ,56 at the forward endsof recesses 40. The hooks when i'n pro 1 jected position engage the eyes and are then I retracted so as to draw side arms 2 tightly against the ends of panel 4, with the operating connections for the hooks adapted to auto 1 l mat ically lock the same in retractedposition. w As an instance of this arrangement the inneri ends of the hook rods may be connected to operating levers 58 which are pivoted to the inner face of panel 4 and which are adapted for manual engagement to swing the same so as to retract or project thehooks, the operating levers being arranged for swinging beyond dead center when retracting the hooks so as to provide a locking connection, which, however, is readily manually released.

The mattress for the bed comprises sepa rate mattress sections for the respective folding sections of the bedstead, and these

mattress sections

60, 61 and 62 are placed one beond another on the spring frame of the edstead when the latter is in operative position, and are adapted for concealment along with the folded bedstead when the structure is arranged for use as a chair. As an instance of this arrangement the

mattress sections

61 and 62 may be removed from the foot and intermediate sections of the bedstead when the latter is to be folded, and the foot section of the bed is then folded onto the intermediate section with these folded sections then folded onto the head section, the extensions 21-22 for pivots 23 providing for this last fold with folded sections 1112 supported on head bar 6 and vertically spaced from head section 10 so that mattress section 60 may be left in place on this head section of the bed.

The intermediate mattress section 61 is adapted to form the seat cushion for the chair and for this purpose may be provided with an ornamentalcover conforming to the chair covering so that when the bedstead is folded with its intermediate section turned uppermost, the mattress section 61 may be placed upon the spring frame of this intermediate section as shown in Fig. 4, in order to provide a usual seat for the chair. As previously stated the mattress section 60 is removed when the bed is folded, and this mattress section,

together with the bedclothes may be concealed in the space between the base of the chair and the under side of the folded bedstead. As an instance of this arrangement a supporting base 7 0 may be hinged to back 1 as shown at 71 with the forward end of this supporting base adapted to be releasably held in horizontal position to provide a support for the mattress section and the bedclothes. The releasable engagement for the supporting base may comprise a hook 7 5 adapted to engage the base rod 30 which extends across the bedstead at the forward end of its head section, the hook 75 being readily accessible for manual release or engagement when panel 4 is removedt 0 that the supporting base 70 may be held in position forming storage space, or may be allowed to drop to the floor to permit bedclothes and the like being placed thereon in the storage space.

By the arrangement as thus described the sections of the folded bedstead are positively supported by resting upon one another with the lowermost head section of the bed held in place in the chair frame by its fixed connections 7 and thesupporting shoulders 45, and the spring frame of the intermediate section of the bed which is turned uppermost when folded, forms a spring seat structureat the proper height so that the mattress section 61 when mounted thereon completes a cushioned chair construction having exactly the same appearance as a similar usual chair lacking the dual utility of the present invention. The folded sections of the bedstead may be fixed against any tendency to accidentally unfold by swinging the brace rod 30 which is positioned at the forward ends of angleirons 11 upwardly over the foot section of the bed when the latter is folded upon the intermediate section, so that when sections 1112 are folded on section 10 this brace rod may be hooked beneath the cushioned portion 8 of back 1 asshown in Fi 4, and the folded sections l1'-12 may be a so held in folded position on section 10 and in fixed relation in the chair frame by suitable releasable retaining means shown as clips 90 pivoted to head bar 6 so that they may be manually turned to engage or disengage the angle-irons 12.

The entire structure is thus rigidly locked in chair forming position when panel 4 is in place connecting side arms 2 and completely concealing the bed structure, and the panel is adapted for ready release and removal to permit disengagement ofvangle-irons 10 from shoulders 45 so that side arms 2 may be swung open and the bedstead unfolded and supported by its legs 25 in operative position.
