Patented July 18, 1933 UNITED STATES LUDWIG- GILCH, OF CIV-IIYCAGOQILLINOIS CONVERTIBLE CHAIR Apphcatonrled January 18, 1932. Serial No. 587,269.

This invention relates to convertible chairs,

with the extended seat so as to form a bed bottom for a cot or bed.

Another object is .to provide` a convertible chair in which the back may be tilted into various inclined comfortable and restful positions.

Another object is to provide a convertible chair in which one or both of the arms may be swung down, out of its upright position when the chair is converted into a bed or cot, whereby to obtain more room and greater comfort.

With these and other objects and advantages in view, this invention consists in the several novel features -of construction, arrangement and combination of parts hereinafter fully set forth and claimed.

The invention is clearly illustrated in the drawings accompanying this specification in which Figure 1 is a plan of a chair with the upholstering removed and embodying asimple form of the present invention, showing the back in a tilted position with the seat moved forward somewhat;

Fig. 2 is a side elevation of the chair with the parts occupying the position seen in Fig. 1, and part of the upholstering broken away;

Fig. 3 is a front elevation of the front portion of the chair frame;

Fig. 4 is a rear elevation thereof; y'

Fig. 5 is a detail horizontal section taken on the line 5-5 of Fig. 2;

Fig. 6 is a View partly in side elevation and partly in vertical longitudinal section taken on the line 6 6 of Fig. l, showing the seat fully extended and the back fully lowered, the upholstering being illustrated by broken lines; Y

Fig. 7 is a vertical longitudinal section taken on the line 77 of Fig. 1, and showing the back in its upright position with the seat drawn back;

Fig. 8 is a vertical cross section taken on the line 8-8 of Fig. 7 'with the upper portieri of the chair broken away; l

Fig. 9 is a detail side elevation of a fragment of one or' the side frames of the chair illustrating the locking means for the hinged arm of the chair, the view being taken in the direction of the arrow 9 in Fig. 3; and l Fig. 10 is a detail' vertical cross Sectio taken on the line 10-10 of 9. l

Referring to said drawings, the reference characters 11,111 designate the side framesand 12 and lthehorizontal crossl bars which 6 connect the side frames. These parts comprise the chair frame. The side frames have arms 14, one or both of which is hinged to the lower portion of the side frame by hinges 15, whereby the arm may be swung down alongside of the lower'portionof the side frame, as seen in Fig. 8. A latch bolt 16 is provided for locking the arm in upright position. The latch bolt is slidably mountedl in a bracket 17 (see Fig. 9)v screwed or otherwise fastened to the inner face of the side iframe, and said latch bolt is adapted to engage in an eye member 18 fastenedv to the inner face of the arm 14. Endwise movementor the nach boit 16 is limited by a rug 75 19 thereon which moves in the cutout part of the bracket 17 as is clearlylseen'in Fig. 9.

Slidably mounted on rails 20' secured to the inner face of the side frames lis the seat, 21, the latter being provided with rollers 22 '80 which run on the' rails 20. The rollers-are mounted in housings23 lscrewed or otherwise fastened to the frame of the seat and may be provided `with anti-friction bearings, as is well understood. `The seat is composed of a lower seat frame 24 and an upper seat frame 25 hinged thereto at its forward end by hinges 26, the lupper Vseat frame 25 being capable of being extended into alignment with the lower seat frame, as is illustrated in Fig. 6, toprovide an extension for the lower seat frame when the chair is'converted into a bed or cot. The lower seat frame is composed of longitudinal side frame mem-A bers 27 connected by cross : trarne members 28 and 29 to provide a substantialseat frame and the upper seat frame 25 is also composed of longitudinal side'frame members 30 connected by cross frame members 81.

The side frames are formed with longitul dinally extending slideways, here shown in the form of slots 11a, formed in the side frames, and the lower seat frame 24 is provided with lateral projections 24a that enter the slots. This arrangement prevents the seat from tilting upward at its rear end whenever the back is manipulated in raising or lowering the same, or in case the weight of a person is applied to the forward end of the seat whenever the latter is adjusted to its foremost position.

Spring constructions are carried by both the upper and lower seat frames and they may be upholstered in the usual manner to provide cushion seats. The outlines of the upholsterings are indicated by the characters 24b and 25". lVhen the upper seat portionA occupies itsnorma-l position, its cushion construction reacts upon the cushion construction of the lower seat portion, thereby providing avery comfortable seat, and when the upper seat' portion isswung into its extended position, the two spring constructions are substantially in alignment so as to provide a spring construction for the bed bot- OIII.-

The back 82 is composed of a frame having longitudinal side frame members 33 connected` by cross frame members 34 and 85. The lower end of the back frame is hinged to the lower seat frame by hinges 36, whereby the back may bei tilted from an upright position, as seen inrFfig. 7, to an approximately horizontalA position, as seen in- Fig. 6, where it rests upon'thecross bar 13 of the chair frame. The backr frame is provided with the usual spring construction. andupholstering, as is customary, the outline of which is indicated by the reference character 32".

Connectible and disconnectible connectionsv are provided between the side frames andthe back frame, whereby the back frame is held in various inclinedpositions and is alsolper-mitted to bevdisconnected from the side frames to allow it to be lowered into an approximately horizontal position for' use asapart of the bedlbottom. As shown, the interconnectionsbetweenthe side frames and back frame comprise slotted plates 37 fas tened tothe inner faces ofthe side frames by screws or the like, the portionsBS of-the slots extending in approximately upright direction and. opening outward rearwardly at their lower ends through curved portions 39. At the curved portions of the slots, the plates are formedwith rests or shoulders 40 lwhich serve aspositive stops-to-holdthe back-in a definite inclined position.

From the sideedges ofthevback frame project/headed pins or lugs 41 which engage in the slots of the slotted plates 37. and cooperate with said slots/to hold the back in'any desired position of inclined adjustment. Grooves 42 are provided in the side frames behind the slots of the slot-ted plates 37, into which grooves project the heads of the pins or lugs 41. Said pins are secured to and extend from plates 43 screwed or otherwise fastened to the side edges of the back frame.

Then in use as a chair, the upper seat portion rests upon the lower seat portion so as to provide a cushioned seat Vand the back is held in upright or tilted position by reason of the engagement of the headed pins or lugs 41 in the slots 38 of the slotted plates 37. A person sitting upon the seat may easily adjust the back to any desired angle of inclination by merely moving his body or pressing backward upon the upper port-ion of the back and the latter may be tilted backward until the pins 41 encounter the rests or shoulders 40 at the lower ends of the slots 38. It will be understood that as the backvis tilted, the seat moves forward. If a person desires to usethe upper seat portion as a foot rest, he merely swings the upper seat portion into its extended position.

To convert the chair into a bed or cot, the back is detached from the side frames by lowering the back until the pins can be moved out of the open lower ends of the slots and then lowering the back to the Cross bar 13. In this position the cushioned parts of the seat and back provide-al cushion bed bottom. In case more room is desired between the two arms of the chair, the latch bolt 16 is drawn out, thereby unlocking the hinged chair arm and permitting it to be swung down, thusexposing one side of the chair.

To restore the chair to normal position, the arm is swung back into upright position and locked in place, the back raised, the pins 41 moved into the open lower ends of the slots 38 and the back is then swung upward until the pins reach the upper ends of the slots. As the back is being swung upward, the seat is drawn back, and when the upper seat portion has been lowered upon the lower seat portion, the chair is in positionto be usedfas a chair.

It is to-be understood that the side frames may be upholstered in the usual manner, so as to correspond with the seat and back, or the side frames, seats and back may be finished with cane or other suitable material. If desired, a separate loose cushion 44 may be provided, which may be used as a pillow when the chair is converted into a bed, or when in use as a chair with the upper seat portion extended as a foot rest, the cushion 44 may be placed on the lower seatportion to provide a raised seat above the foot rest.

I Claim as new, and desire to secure by Letters Patent:

A convertible chair comprising in combination, a chair frame hav-ing side frames, horizontal cross connections therebetween, and a pair of rails, a seat movably mounted on said rails and comprising upper and lower sections hinged together at the front, whereby justed into inclined positions with the pins traveling in the straight portions of the slots, and whereby the stop shoulders positively support the back in its lowermost inclined position, and whereby the pins may be moved out of said slots at the lower ends thereof, permitting the back to lie substantially horizontally with the upper hinged portion of the seat extended horizontally.
