DAVENPORT BED 4 Sheets-Sheet 4 Filed May 15, 1963 FEE United States Patent O 3,209,377 DAVENPRT BED Martin Fox, Chicago, Ill., assignor to The Seng Company, a corporation of Delaware Filed May 15, 1963, Ser. No. 280,652 3 Claims. (Cl. 5-13) This invention relates to a davenport bed, and in particular it relates to such a bed in which the sleeping surface extends longitudinally between the davenport arms and in which the base has a one-piece front rail behind which the folding bed mechanism is completely concealed in davenport position.
A common objection to davenport beds which have a folding bed frame is that in davenport position the convertible nature of the piece is apparent because the front rail is longitudinally split. The base has a very low fixed front rail, and a front board carried on the folding bed frame extends upwardly from the front rail of the base. Accordingly, even though the lixed front rail and the movable front board are upholstered in the same fabric the line of division between them is plainly visible which makes it obvious that the piece is convertible.
The present invention provides a davenport bed in which the base has a relatively high fixed front rail, and the entire folding bed mechanism occupies a space behind the front rail and substantially entirely below the plane of the top surface of said rail.
The principal object of the present invention, therefore, is to provide a davenport bed in which the base has a fixed front rail that completely conceals the bed mechanism in davenport position.
Another object of the invention is to provide a davenport bed in which an inner bed section is supported upon rear links and front links for movement between a bed position entirely above the front rail and a folded position a substantial distance below the plane `of the top of the front rail, so that the articulated intermediate and outer bed sections, the latter of which overlies the inner section in davenport position, may be substantially entirely below said plane.
The invention is illustrated in a preferred embodiment in the accompanying drawings in which:
FIG. 1 is a longitudinal sectional View of a davenport embodying the invention with the articulated bed sections in bed position, taken substantially as illustrated along the line 1-1 of FIG. 2;
FIG. 2 is a fragmentary plan view on an enlarged scale, taken substantially as indicated along the line 2 2 of FIG. l;
FIG. 3 is an enlarged fragmentary plan view of a pontion of FIG. 2, showing the inner bed section and the links by means of which said bed section is supported upon the davenport base;
FIG. 4 is a view similar to FIG. 1 but with the folding bed in an intermediate position between bed position and folded position;
FIG. 5 is a View similar to FIGS. 1 and 4 with the bed in folded position; and
FIG. 6 is a view similar to FIGS. 1, 4 and 5 with the bed in a position intermediate the positions shown in FIGS. 4 and 5.
Referring to the drawings in greater detail, a base, indicated generally at 10, has a pair of parallel end rails such as the end rail 11, a back rail 12 and a front rail 13. Also included in the base are arms 14 and an inclined back rest 15. A convertible bed mechanism, indicated generally at 16, takes the form of a prefabricated subassembly which is mounted in the base by a pair of supporting brackets 17 that are secured to the end rails at 17a and to the front rail 13 at 17b (see FIG. 3).
A folding bed mechanism, indicated generally at 18, is of a conventional type which has its side rails extending longitudinally between the ends of the base, so that the head of the bed is adjacent one arm and the foot adjacent the other arm of the danvenport. Thus, the folding bed has an inner section 19, an intermediate hinge section 20, and an outer section 21; and as seen in FIGS. 4 and 5 when the bed is folded the inner section 19 is at the bottom, the hinge section 20 extends generally upright at the front of the davenport base, and the outer section 21 overlies the inner section and is generally parallel thereto. 'I'he outer section has outer folding legs 22 operated by links 23 that are pivotally connected to the legs and to the hinge section 20; and intermediate legs 22a are operated by auxiliary links 23a from the links 23.
The inner bed section 19 is carried upon the supporting brackets 17 by means of a pair of rear links 24 which are pivoted on the brackets at 25 and pivotally connected to the ends of the inner bed section 19 at 26, immediately adjacent the inner side rail of the bed. Likewise supporting the inner bed section 19 are front links 27 which are pivotally mounted upon the bracket 17 at 28 and pivotally connected to the inner bed section 19 at 29. The rear links 24 carry fixed plates 30, and pivots 31 on said fixed plates receive the inner ends of actuating links 32 which are pivoted at 33 to hook shaped locking plates 34 that are mounted upon the ends of the inner bed section by pivots 35. As best seen in FIGS. 4 and 5, the locking plates 34 are rolled outwardly in movement from intermediate position to folded position of the bed, and in doing so they engage locking studs 36 which pivotally connect adjacent ends of a locking link 37 and a guide link 38 that are connected, respectively, to the outer bed section 21 at 39 and to the intermediate hinge section 20 at 40.
The xed plates 30 and the rear links 24 also carry spring studs 41, and tension springs 42 engage said studs and studs 43 on fixed plates 44 connected to the front links 27. The fixed plates 44 are connected by a tie rod 45 which gives necessary rigidity to the link assembly.
Comparison of FIGS. 1 or 4 with FIG. 5 shows that in bed position the rear links 24 extend upwardly and forwardly, while the front links 27 extend upwardly and rearwardly, so that the rear and front links converge in bed position; while in folded position the rear links 24 extend downwardly and rearwardly in a nearly vertical disposition while the front links 27 extend downwardly and rearwardly in a nearly horizontal disposition.
Analysis of the relative positions of the links 24 and 27 in FIGS. 4 and 5 shows that, in moving from folded position to bed position, the links 27 move first to a horizontal position, during which time the rear links 24 must pivot a short distance rearwardly. This swings the entire folded bed structure rearwardly so as to provide slight additional clearance with respect to the front rail 13. The front links 27 then swing upwardly and forwardly to a nearly vertical position (FIG. 6) while the rear links 24 move to their horizontal dead center position. Accordingly, at this point the entire folded bed frame is in a sharply inclined position, with the front portion of the inner bed section 19 above the plane which it occupies in bed position. The rear of the folded bed is still very low, and for the most part is simply swung forwardly to clear the inclined back rest 15. During a second part of the movement from folded position to bed position the rear links swing from their horizontal dead center positions upwardly and rearwardly to bed position to elevate the rear of the inner bed section 19, while the front links 27 swing rearwardly and thus lower the front of the inner bed section to bed position. It is seen that in bed position the converging orientation of the rear links 24 and front links 27 provides completely stable support for the inner bed section 19.
During the movement of the bed from the folded position of FIG. 5 tothe intermediate position of FIG. 4 the action of the links 24 acts through the links 32 to roll back the hooked locking plates 34 and release the locking studs 36, so that the outer bed section may be swung outwardly to bring it and the end section 20 into horizontal alignment with the inner section 19.
The foregoing detailed description is given for clearness of understanding only and no unnecessary limitations are to be understood therefrom, as some modications will be obvious to those skilled in the art.
I claim:
