BED DAVENPORT Application filed February 27,1928. Serial No. 257,241. Y i I V 7 Theinvention relates to davenports and more particularly tothat type of davenport convertible into a bedl I a An object of the invention is to provide; in

that type of bed davenport including an invertible seat member, animprovedform of linkage which afi'ordsvsimplicity, compactness andrigidity of construction, the linkage being of such character as to afford a rigid, mutual support for the bed members of the davenport when they are extended to {bedforming position, and suitable provision being made forinsuring against thecollapse of the rear portions of the elevated bed.

Another object of theinvention is toprovide spring means acting on swinging'supports for the invertible seat member to facilitatemanipulation of the linkage and to insure proper folding and unfolding of the linkage. v V V V A further object of theinvention is to perfect details ofconstruction generally, v k

. The invention further consists in the several features hereinafter set forth andimoren 4 particularly definedby the annexed claims.

In the accompanying drawings, 1- is va transverse sectional v ew'of a bed davenport I embodying the invention;

The upperforwardlyprqectmg ends, of

tending longitudinallyrof the davenport.

A u shaped frame member 22 of angle crosssection has its endssecured to the angle member: 21 near the, ends of the latter to form a rectangular seatframe to the outer flanges of which I are secured surrounding, wooden strips 23' for 'facilitating upholstering. A The endsof theangle' member 21extend beyond the ends oftheangle member 22 inorder that the, hookshaped arms a 17- will clear the wooden strips 23 at the ends of the seat frame,

andj in theseat-forming position of Fig.1, the

lower 7 edgev of;v the forward WOO en: strip 23 liesv close to the upper edge ofthe fixed front rail-1 1., a I.

*The seat frame has mounted thereon two setsof upholstery springs, 24 and 25v which project fromopposite facesfofithe frame. The springs 24 constitute part ofthe seat upholsteryv and have placed thereabove seat cushions 26 whichcmay be offthe removable and reversible type-,while the coiled springs 25 on the, other face of the seat frame form part; of the upholstery of a bed section 27, ashereinafter described; ,When a boxiseat of the swinging arms 17 providing the necessary clearance for the inversion of the seat.

When in the position shown in Fig. 1, the sides of the seat frame ad acent its rear portions rest on brackets 28 secured to the end frames 10, and the swinging arms 17 are limited in their backward movement by their res ctive engagement with pins 32 secured to t e upper portions of the mounting plates 12. At each side of the davenport, a coiled spring 34 in tension has its upper end anchored on the pin 32 and its lower end anchored on the rear end of a bar 35. secured to and projecting rearwardly from the lower portions of the swi 'n'g arm 17, thereby urging the bar upwar y to exert a forward thrust on the arm '17. A bed section 36 includes an angle frame 37 similar to that of theseat frame and has secured thereto a set of upholstery springs 38. The forward portions of the bed frame 37'have upstanding brackets or plates 39 secured thereto, one at each end of the frame, and each of a pair of crossed links 40 has a 'votal connection 41 at one end with each racket 39. The other end of each link 40 has a pivotal connection 42 with one of a pair of brackets or. plates 43 fixedly secured to the opposite end portions of the seat frame and adjacent the pivotal connections 19 for the seat-supporting arm 17. The crossed links 40 are dis osed on opposite sides of their brackets 39 an 43 and bear laterally against the brackets. In the seat-forming position of the davenport shown in Fig. 1, the bracket 43 depends from the seat frame. The crossed links 40 ivotally connecting these brackets are of so stantially thesame length but are so related that the forward pivotal connection 41 on the bracket 39 of the bed frame 37 is at a lower elevation than the Other pivotal connection 41, while at the seat frame bracket 43 the forward pivotal connection 42 is spaced above the other. The pivotal connections 42 are at regions somewhat below and to the rear of the pivotal connection 19 on'each seat-supportin'garm in the seat-form ing position of the davenport, so that upon the inversion of the seat member the links 40 will be both lifted and drawn forward.

The rear portion of the bed frame 37 carries aligned pins 44 at its opposite ends on which egs or links 45 are each pivotally mounted at an end portion. The other end portion of each leg or link 45 carries a pin 45 which is slidably mounted in a horizontally disposed slot 47 formed in a horizontal bracket 48 secured by screws 49 or other suitable fastening means to the lower and rearward portions of each mounting plate 12. A swinging strut 50 has one end pivotally connected by a pin 51 to each leg 45 at an intermediate point on the leg near the pivot pin 44, and the other end of the strut 50 is pivotally mounted on a pin 51 secured to the mounting plate 12 at a point forward of the bracket 48 and slightly above the plane of the slot 47. The legs or links 45 serve to support the rear part of the bed when the seat is inverted, as seen in Fig. 4 in which position the pivotally-mounted struts 50 hold the link in a vertical position. The seat member when inverted to bed-forming osition is supported in part by the usual f0 ding legs 52 which are swung down from the outer portion of the inverted seat frame to prevent tipping of the bed. The bed-supporting legs 45 and their connected struts 50, all formed of flat metal bars, are provided with suitable 011'- sets, as best seen in Fig. 5, to provide operating clearance.

In order to support the rear bed section 36 from the floor when it is stored beneath the upright seat, an angle bracket 53 is secured to each end of the frame 10 adjacent the rear end of the rear bed section to receive the lower edge of the bed section frame 37. The brackets 53 limit the downward movement ofthe rear bed section to a point spaced a suitable distance from the floor and also form supports on which the bed section frame may slide and pivot during the manipulation of the linkage.

To change the davenport from the seatforming position of Fig. 1 to the bed-forming position of Fig. 4, the operator grasps the rear portion of the seat member and draws it forwardly and upwardly, a passing position of the moving parts being shown in Fig. 3. On the first part of the upward movement of the seat member, the seat-supporting arms 17 swing forwardly towards the fixed front rail 14 under urge of the coiled springs 3 which assist this movement. The arms 17 are limited in their forward travel by their abutment with the flanges 15 of the mounting plates 12, and the pivot pins 19 on the forwardly projecting portions'on the arms assume positions forward of the fixed frontrail. During this movement of the seat-supporting arms 17, the pivot pins drop no substantial distance in elevation. Simultaneously with the initial movement of the seat member, the forward portion of the bed frame 37 is lifted by the links 40, the rear portion of this frame pivoting momentarily on the bracket 53 until the bed-supporting legs or links 45 pass over center with respect to the struts 50. As soon'as such point is reached the action of the crossed links 40 is to lift the rear bed section 36 in a substantially horizontal position until the During this upward movement of therear finally reach positions at the rear ends of.

these slots, at which point the bed-supporting legs or links assume a vertical position as seen in Fig. 4:. In this position of the ;angle brackets"53. In the seat-formingposition ofthedavenpornithe bedding is folded {in the; spacebetween the .bed' sections. During the folding operation the .retractile legs the struts 5O prevent accidental forward displacement of the pins 46 at the lower ends of the bed-supporting legs to insure against collapse of the rear bed section. In the bed-. forming position of the davenport, as seen in Fig. 4, the CIOSSBCl'llIlkS 40 connecting the brackets 39 and 43 on the rear and front bed sections, respectively, are disposed in such relation that they rigidly bracethe'rear bed section from the forward bed section against either upward or downward movement, one.

of these links forming a tension member while the other simultaneouslyforms acom.

pression or strut member; The lateral abutment of the links 40 with opposite sides of' the brackets 39 and 43 serves to avoid any undesirable side play between thebed sec tions. The pivotal connections of theseliiiks with their brackets, however, permit the smooth folding and unfolding of the linkage and provide a supporting means whereby the rear bed section is raised or lowered in a substantially horizontal disposition. Nhen the seat member reaches its inverted position the folding legs 52 carried by the seat frame are swung down as seen in Fig. '4: to prevent tipping of the completed bed. Bedding 55,

which may include. a hinged mattress, is placed above thecoiledsprings 25 and 38 of' the bed sections, and may, if desired,be fastened to the bed sections in order that itniay fold and unfold with the davenport. l

To return the parts from the open position.

of Fig. 4 to the closed position of Fig. 1, the

supporting legs 52 are swung back to folded position along the seat frame and the movements of the seat member are reversed, the

seat frame being lifted and swung upwardly I,

while the bed frame 37 simultaneously de- -scends to a position behind the front rail.

During this initial lifting movement of the inverted seat frame, the seat-supportingarins 17 are retained in their forward position by the tension of the springs 34 and the links 40 are urged rearwardly which causes the rear bed section to be also urged rearwardly simultaneously. with its downward movement,

, The rearward displacement of the bed section causesthe bed-supporting legs or links 45 to pivot on the pins 51 on the ends of the struts 50, thereby causing the pins 46 at the lower ends of the legs 45 to move forwardly in the slots 47. As the linkage folds further from the position shown-in ,Fig. 3, thefurther descent of the bed. section causes the rearward movement of the seat-supporting arms 17 simultaneously with'the lowering of the seat frame to its seat-forming position, the seat-supporting arms be'inglimited in their rearward movementwby1 their abutment with the stop pins 32. vInthis position of .=the linkage, the, rear portions of the seat frame rest. on the brackets-28, While' the rear bed'section is suspended on the -links-40. and"rests on the sprin'gs3t retard the downwardmovement of theifseat frame 1 and 1 bed frame to insure smooth operation, and the travel of the legs 45 in the slots 47 serves to minimize the rearward movement of the bed frame. 3

The longitudinalaxes of the crossed links 40 remain in crossed relation in the entire travel of the seat member from its seat-forming position to its inverted bed-forming position, thereby enabling the bracing effect of the links to be attained when the parts are intheir bed-forming position and also preventing binding of the linkage in any position of the linkage. l

The invention provides a davenport in-' eluding a simple but effective type of linkage which provides rigid construction, compactness and smooth operation.

What'l'claim as new and desire to secure by Letters Patent is:

1.],In abed davenport, the combination of aseat member invertible to bed-formingpd s1tion,swinging supporting arms on which said seat member isipivoted for inversion, a

bed member having an articulated connection Jwith said seat member for movement to elevated bed-forming position upon the inver- S1011 of said seat member, astop member limiting the rearward movement of each sup anchored at itsupper end on said stop member and at itslower. end on the lower por" tions of the adjacent supporting arm for urging said arm to a forward position upon the inversion of said'se'at member and for retarding the return movement of said supporting arm during the subsequent movement I of the seat member to itsv seat-forming po sition, I

porting arm, and a retractile coiled spring 2. In abed davenport,the combination of said seat member to bed-forming position,

a bracket secured to each of said supporting plates and having a substantially horizontal slot, a. linkmember' pivotally secured to said bed member to extend there-below in substantially upright position in the elevated bed-f0rming position of said bed member and said link member being connected to said 5 bracket for sliding travel in said'slot, and a,

strut member ivotally mounted on said supporting plate ibrwardly ofsaid slot and hav- I ing a pivotal connection with an intermediate portion of said link member whereby to brace said link member in its bed-supporting position.

In testimony whereof I afiix my signature.
