SOFA-BED.

1,1O,34Q. Specification of Letters Patent.

Application tiled January 5, 1914. Serial No 810,374.

To all 'whomit may concern.' A

Be it known that I, Louis a subject lof the lEmperor of Germany, and a resident of the city of Chicago, county of Cook, and State of Illinois, lhave invented certain new and useful Improvements in VSofa-Beds, of which the following is a. specification. Y

My invention relates to improvements in sofa beds and hasfor its object the production of a sofa bed which may be readily and easily converted from a sofa to a bed and vice versa and one which will be durable and economical in construction and efcient in use.

Other objectsl will appear hereinafter.

The-invention consists in the combinations a'nd arrangements of parts hereinafter described and claimed.

, The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a vertical section ofa sofa bed embodying my invention, the section being taken just inside of one of the end members of the frame of the device, Fig. 2 is un enlarged fragmentarydetail section taken on line w--w of Fig. 1, Fig. 3 is a fragmentary detail illustrating the connection of one end of the sofa back member with the outer sectioniof the bed bottom, Fig. 4 is a front elevation of the device in unfolded condition the upper end portion of the frame of the device beingbroken away, Fig. 5 is a section taken on line .1f-a: of Fig. 1., Figs. 6 and 7 are enlarged fragmentary detail sections taken on lines y-y and z-z rcspecLively of Fig. 1, and Fig. 8

is a top plan view ofthe device in unfolded condition, the frame thereof being shown in section.

The preferred form of construction as illustrated in the drawings comprises a frame or body consisting or end members 1 which are lspaced A)art and `rigidly conuected by a rear piece 2 and a front bar 3. Arranged in the frame thus formed is the foldable bed bottom consisting of a plurality of pivotally connected sections 4, 5 and 6, the innermost section# bein pvotally connected at its rearward en with arms 7 which are pivoted at 8 to angle irons `9 rigidly 'secured to theinner sides of frame members l. The arrangement is such that, when the bed bottom ism folded condition,

as shownin full lines in Fig. 1, the upper ends of the members 7will rock rearwardly to permit of the bed bottom section .4 assuming a position.in close proximity with the frame 'member 2 so as to permit of a maximum utilization of the space within the frame of the device `for storage purposes,

as for the mattress or bed clothing arranged wardly being limited in their forward movement, by engagement of the lower ends thereof with flanges 10, as will be readily understood.

Rigidly connected at 11 with the outer bed bottom section 6 are the free ends of levers 12, the opposite enils of said levers being fulcru'med at 13 to the frame members 1, straps or cleats 14being`hprovided at the inner-sides of the framemembers 1 to reinforce the sameV at the points of connection therewith of said levers. -With this arrangement in the .unfolding of the bed bottom, the upperend of the section- 6 is engaged and rocked forwardly, the forward rocking being, of course, about the fulcrums 13 of levers 12. In this forward rocking of the section 6, the sections 4@ and 5 lwill be moved therewith and, when vthe section 6 reaches a horizontal position, said sections 4 und 5 will be in a corresponding coplanar position. The Section5 is provided with rollers 16 adapted, when the bed bottom is unfolded. to rest upon angleirons 17 provided uponythe inner sides of the frame members 1 in order to support said bed bottom section in loperative position. Said supporting members 17 are comparatively short so that in the rearward or folding movement of the bed bottom, the rollers 16 will move rearwardly-and downwardly out of qngagement therewith in order to permit of the collapsing or folding of the bed bottom to the condition shown in full lines in Fio. 1.

'The rearward end portion of the section 6 of the bed bottom is supported-in operar;

tive position, when the bedV bottom is unv idly secured at their upper ends to the sides of said section, the legs 18 and levers l2 being rigidly connected at their points of intersection .in order to produce a. rigid construction.

Loosely mounted between the frame members 1 is the sofa seat member 19, substantially rectangular in form and suitably upholstered. Said seat member is provided at its under side with cleats 19 adapted, when the former is in operative position, to rest upon the upper edges of a storage receptacle or compartment 20 rigidly secured in position in the lower portion of the frame of the device at the front end thereof. The receptacle 20 is provided for the storage of bed clothing or other articles desired, and the ends thereof are spaced slightly from the corresponding sides of the frame members 1 in order to permit of clearance for the va rious levers employed in the construction.

The seat member 19 is provided at its respective ends adjacent the rearward end of said member with angle irons 21 rigidly secured thereto. The rearward ends of angle irons 2l are provided with laterally projecting pins 22 which engage elongated slots 23 provided in levers 24, the front ends of said levers being connected by means of links 25 with the angle irons 21, as clearly shown in Fig. 1. This arrangement permits of upward rocking of the seat member in order to permit of access being gained to the storage receptacle 20, it being clear that with the construction set forth, upon upward pressure upon the forward end of the seat member, the pins 22 will slide forwardly in slots 23 of` members 24 and the seat member will turn about the points of pivotal connection thereof with the links 25, the rearward ends of the links 25 rock-- ing upwardly in this operation and serving to hold said seat member in elevated position, as shown in dotted lines in Fig. 1.

The rearward ends of the levers 24 are angular in form and pivotally connected at 26 with levers 27 which are fulcrumed at 28 to the inner sides of frame members 1. The forward ends of levers 2 4 are pivotally connected by means of links 29 and 30 with the legs 18- carried by the bed bottom section 6. Provided upon the 'legs 18 are laterally projecting stop pins 30 which limitrearward rocking of the links 30. The arrangement is such that the seat member will be supported by the levers 24 and in the unfolding movement of the bed bottom, said seat member will be carried forwardly in a substantially horizontal position and automatically transferred from its operative position, as shown in full lines in Fig. 1, to a position resting upon the Hoor at the under side of the bed bottom, as shown in dotted lines in said figure. Conversely, when the bed bottom 65 is folded, said seat merinber will be carried upwardly and transferred from its dotted line position in Fig. 1 to its full line or operative position. The links 29 and 30 coperate with the lever 24 in this operation to constantly maintain the same in a substantially horizontal position and hence to maintain the seat member 19 in a corresponding position, as above set forth Also arranged between the frame members 1 is the sofa back member 31 which is carried by the section 6 of the bed bottom. Said back member is movably connected with said bed bottom section through the medium of links 32 and 33, corresponding ends of said links being pivotally connected with angle irons 34 which are arranged upon the rearward side of said back member adjacent the lateral edges thereof. The links 33 are of the splitlink type, the outer ends of the pivotally connected sections of each of said links being extended as at 35, in Fig. 3, in order to engage against the adjacent portions of the bed bottom section 6 and angle irons 31 to serve as stops in order to hold said links against assuming dead center positions and in order to insure the breaking of said links in one direction. The angle irons 34 are provided with elongated slots 36 for engagement by the links 32 in order to. permit the sliding of the corresponding ends of said links relative to said angle irons under the influence of rods. 37 which are connected at corresponding ends with said links 32, the opposite ends of said rods being connected with links 29, as clearly shown in Fig. 1.

Elongated slots 38are provided at the points of pivotal connection of the rods 37 with the links 29 in order to permit of slight relative movement. The links 32 are connected intermediate their ends with corresponding ends of links 39 which are pivotally connected at their rearward ends with the angle irons 34. The arrangement is such that, in the -sliding movement of the lower or rearward ends of links 32 in the slots 36, the forward or upper end of the sofa back will be rocked rearwardly to the position shown in full lines in Fig. 1. With this arrangement then, the upper end of the sofa back will normally assume the position shown in full lines in Fig. 1. As the bed bottom is unfolded said back member will be carried thereby to a position at the under side thereof when unfolded. As the bed bottom is unfolded, the rods 37 are moved rearwardly causing the upper or forward end of the back member to move to the dotted line position shown in Fig. 1. Conversely, as the bed bottom is folded, the rods 37 are moved upwardly causing the lower ends of links 32 to be slid forwardly in slots 36 in order to cause the forward or upper edge of said back member to rock rearwardly.

The forward end of the bed bottom`sec tion 6 when in unfolded position, is supported by legs 40 which are pivoted at 41 to angle irons 42v secured rigidly to the forward or upper edge of back member 31, the supporting of the bed bottom section being effected indirectly through said back member and links which connect the same with said bed bottom section. The upper ends of links 40v are provided with forwardly projecting pins or lugs 43 which engage notches 44 provided in the front bar of the bed bottom section 6 when said legs are in operative position. Also provided in said bar of section 6 are notches 45, the upper side of said bar being provided with elongated slots 46 which extend between the notches 44 and 45, as clearly shown in Fig. 8. Coperating with the legs 4() are links 47. The arrangement is such that, when the legs 4Q are moved upwardly, the upper ends thereof will project through the slots 46, the pins 43 being thereby disengaged from the notches 44. In this upward movement of said legs, the links 47 will operate to cause the upper ends thereof to be rocked inwardly to engage the pins 43 with the notches 45, the lower ends of the links 47 engaging elongated slots provided in the legs 40 in order to permit of relative movement between said parts such as is required in this operation. Hence, with the construction set forth, folding and unfolding of the legs 40 will be effected by movement of the pivotal points 4l of said legs toward and from the bed bottom section 6. This movement of said pivotal points is secured through the movement of the upper or forward edge of the back member toward and from the bed bottom section 6 in the folding and unfolding of the bed bottom, as above described. This movement of the back member being effected automatically withthe folding and unfolding operation of the bed bottom. the folding and unfoldingr of the supporting legs 40 will also be automatically effected, the arrangement being such that, when the bed bottom is unfolded, said legs will be racked to operative position, and when the bed bottom is folded, said legs will be rocked upwardly into close engagement and parallel with the front bar of the section 6 of the bed bottom.

Provided at the upper end of the bed bottom section 6 is a handle 48 provided to facilitate the unfolding and folding operation of the device. Said handle is preferably of such a length as to permitof the person operating the device, when unfolding the same, to stand a sufficient distance away from the seat member 19 as to avoid being struck by the forward edge of the latter when said seat member moves forwardly as is the case in the unfolding operation of the device.

Provided at the front side of the frame of the device immediately' below the seat member 19 is a cross piece 49 which serves normally to close or tgaverse the gap which otherWise is left between the frame member 3 and the seat member. This member 49 is supported by bell crank levers 50 which are fulcrumed at 51 to the inner sides of frame members 1. The rearward ends of said bell crank levers are connected by means of helical tension springs 52 with the bed bottom section 6, the arrangement being such that, when said bed bottom is in folded condi tion, said springs will hold the bell crank levers 50 in such a position as .to adapt the same to support the member 49 in operative or traversing position. As the bed bottom is unfolded, said springs will cause the forward ends of said bell crank levers to rock downwardly in order to drop the member 49 to non-traversing position and thereby provide clearance.for the levers 1'2 and 27. The movement of the member 49 is thus controlled automatically by the movement of the bed bottom. The springs 52 in addition to serving as means of operation of levers 50, serve also to facilitate the folding and unfolding operation of the bed bottom, the tension of said springs, when the bed bottom is in folded condition, being such as to tend to unfold the bed bottom, and when the bed bottom is in unfolded condition, the tension of said springs is such as to tend to fold the same.

Provid :l at the upper edge of the frame member 2 is a pivoted leaf 53 adapted n0rmally to close the opening or space between said edge of said member 2 and the upper edge of the bed bottom section G when the bed bottom is in folded condition. Said leaf 53 is provided at its forward edge with a depending lip or flange 54 adapted for engagement with the upper edge of bed bottom section in order to releasably lock the same' against unfolding movement, it being required. in the unfolding of the bed bottom to first swing the member 53 upwardly in order to release the section 6.

A sofa bed of the construction set forth may be readily and easily manipulated and will be found highly efficient in use.

While I have illustrated and described the preferred form of construction for carryin my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
