FOLDING BERTH AND SEATING UNIT Filed March 24, 1950 6 Sheets-Sheet 6 FIG.|4. 55

INVENTOR. WARREN Jx WILLIAMS Fatented cc. 1, 1953 UNITED i smear orrlcs This invention relates to folding berths and, more particularly, to the duplex type adapted, when not in use, to be swung into a recess in a bulkhead or partition wall, and particularly adapted to ship staterooms or other sleeping quarters (and also to railway sleeping cars and similar installations). The invention is shown in connection with ship sleeping quarters which, when not used for sleeping, is used as a lounge or parlour, and for this purpose, has a seat or sofa.

One of the objects of this invention is to provide a duplex folding berth in which the upper berth may be turned more than 90 to an inclined or slanted position in which it can be readily made-up by a person standing on the floor (i. e., without having to climb up to make the bed). An allied object is to provide means enabling the upper berth to be selectively turned 90 to sleeping position, or a greater angle (such as 115) to said make-up position.

Another object of invention is to provide a safety lock or latch arrangement which will assure that the berth will remain positively in selected position, whether that be the normal, closed position, or the open, sleeping position, or the aforementioned make-up (slanted) position.

A further object of invention is to provide in the folding berth of the type described, an equalizing spring which will make easier the task of returning the berth to closed position. An allied object is to provide an equalizing spring for a folding berth which is readily adjusted to regulate the tension of the spring, as may be required.

A still further object of invention is to provide the folding berth with an improved form of berth-ladder which has a number of features which will be fully described and pointed out in the ensuing specification.

For the attainment of the foregoing and such other objects of invention as may appear or be pointed out herein, I have shown a, preferred embodiment of my invention in the accompanying drawings, wherein:

Fig. 1 is a front View of the improved folding berth in non-sleeping position, closed except for the sofa or seat;

Fig. 2 is likewise a front view but showing the upper berth in open or sleeping position;

Fig. 3 is a front view similar to Fig. 2, but showing both the lower and the upper berths in open, sleeping position, and with the berth-ladder extended to the floor;

Fig. 4 is a side view of the improved folding berth, with the upper berth in open or sleeping position;

Fig. 5 is an elevational section taken on the line 5-5 of Fig. 2, and showing the upper berth in closed position and the lower berth in open or sleeping position;

Fig. 6 is a horizontal cross-section through the improved folding berth;

Fig. '7 is a fragmentary sectional elevation taken substantially on the line 'l--':l of Fig. 2, showing the upper berth in make-up position;

Fig. 8 is a fragmentary section, in elevation, taken on the line 8-43 of Fig. 6, showing particularly, the equalizing spring;

Fig. 9 is a section taken longitudinally through the improved berth on the line 9-4) of Fig. 6;

Fig. 10 is a fragmentary front View of the front of the upper berth (in open or sleeping position), showing the berth-ladder in reposed position;

Fig. 11 is a front view of the berth-ladder in its operative position;

Fig. 12 is an enlarged detail of the ladder articulation, taken on the line l2--l2 of Fig. 11;

Fig. 13 is an enlarged detail of the ladder construction taken on the line iS-l 3 of Fig. 10; and

Fig. 14- is a sectional view taken on the line I l-l4 of Fig. 11, showing further details of the ladder construction.

Referring first to Fig. 6, it will be seen that the improved folding berth of this invention is disposed between a pair of stanchions it, ill, which extend normally from bulkhead l. Referring now to Figs. 4 and 5, it will be seen that the upper berth 2D is pivotally mounted (between said pair of stanchions [0, ill) to turn on axis 2| from the open or sleeping position (shown in Fig. 4) to the closed position (shown in Fig. 5); it will also be seen that the lower berth it is similarly pivotally mounted to turn on axis 3i from its closed position (shown in Fig. 4) to the open or sleeping position (shown in Fig. 5). The structure of the two berths, e. g. that of the upper berth, is best shown in Figs. '7 and 6, from which it will be seen that the berth (the upper berth, that is) has a floor panel 22 (Fig. 7), constructed of hollow plate construction and end walls 23, 23 (Fig. 6).

The bottom face of floor panel 22 presents a smooth, uninterrupted surface or plane 2%, which is decoratively treated because when the berth (upper) is closedas it is in Fig. l--said decorated or finished surface 24 will be exposed, as shown in said figure.

To open the upper berth from its closed position (shown in Fig. 1) a hand-latch 25 is provided, Fig. 1, at one side. A similar hand-latch 35 is provided for the lower berth. Stops are provided to limit the extent of opening or the berths to open position; the stops associated with the lower berth 30 will be first described, because these are simple, fixed stops (unlike those of the upper berth, subsequently explained). Referring to Fig. 4, a lug or stop 36 projects laterally-on both sides-from floor panel 32 of the lower berth 30, which, when the berth is turned 90 to open position (see Fig. 5) abuts and is stopped by a lug or stop l6 provided in the side stanchion Ill, or rather, stanchions II], II).

Similar fixed stops are not provided in connection with the upper berth, because of the feature of the improved berth of this invention which enables the upper berth to be turned more than 90, to an inclined or slanted position in which it can be readily made-up by a person standing on the floor. Upper berth is shown in Fig. 7 in said inclined make-up position. That is, whereas in sleeping position, upper berth :26 is turned 90 (to.positionv ofEFigy-A). in the make-up position,.it is turned '115f21Fig. 7. I have found this angle of slant to be satisfactory, but it is to be understood thatmyxinvention is not limited to this, or any other angle.

To enable the upper berth. 28 to be selectively turned 90 to sleeping position or 115'to makeup position, the stops on the berth (unlike {3,6, 36) are not fixed but -.ar.e adjusted selectively. For this purpose, a shaft-.21, see Fig.'9,:extends across the length of the upperberth 26, being mounted in end walls 23 for an extent ofturning, and is provided atboth ends with an arm orstop-arm 26, :26. .ShaftZ? is turnable (by means subsequently described) from a position in which it is normal to the floor plate 24 of the berth 20 (as in Figs. 5 and 4) to a position in which it abuts or lies against the floor plate 24 (as, in Fig. 7). Shaft21 is journaled in the walls 23 to rotate about a constant/axis. The

ends of shaft 21 are fixed to stop lugs 26, 25 so that stop lugs 26, 261may be turned to lie against fioorplate 2d by turning the shaft2'l. When the end stop lugs 26, 25 are in said normal position (Figs. 5-4), they contaot, vwhenthe upper berth is turned 90 (as in Fig. 4),,a predetermined surface l5, l5 of stops it, I l-fixed in the side stanchions H3, H3 see Figs. 4, 5 and-also Fig. 9. Referring particularly to Fig.4, the stop surface I5 is so disposed that, with theend stops .26, 25 in saidnormal position ,(of Figs. 5 -4), these stops *26-[5 will engage to limit the open turning to 90 as in Fig, 4. But ifshaft 21 had been turned to lie end'stops 126526 against-floor plate 24 (as in Fig. 7), stopzsurface I5 will not be effective to limit the turning to said 90. Instead, the berth will continue turning-to 115, as explained ab0ve,until the -side,-rather than the end, of stop 26 abuts .a second (inclined) stop surface l3 provided on stop lugs M, M.

To enable shaft 21 to be turned to selective position, its end stops 26,126 as just described, it is provided with a centrally-disposed bevel gear 28, Fig. 9, and the plate 24-see Fig. l-.-is provided with a small aperture '29, wherethrough may be inserteda hand-tool 9 which has a'bevel gear 8'at its inserted end. After insertingtool 9 to mesh its gear 8 with bevel gear. 2-9,;it is turned to impart a turning in the desireddirection, to shaft 21.

It had been mentioned earlier that the berth may be opened and closed by manipulationof hand-latches 25 (upper berth) and (1ower berth) Fig. 1. These will now be describedpwith reference toFigs."4,.5 and 'ig -andalso'rFigrzG. Se

cured on the two side trunions II, II, Figs. 64, upon which upper berth 20 is pivotally mounted (to turn on axis 2|, 2| as before described) are two stationary discs l1, H, see especially Figs. 5-4-7. As there shown, the periphery of disc (i. e., discs) I! is provided with a plurality of notches in which may be received a lug 48 provided at the distal end ofa lever 41 pivotally mounted, at 45, to theeend wall 23 of :the upper berth. At said distal end of lever "41 but on the Side opposite said lug 48, is articulated one end of a link 35, the other end of which is articulated to ;one-arm of a bell-crank lever 44, pivotally mounted at 33. To the other arm of the bell-crank lever 44 is articulated one end of the hand latch .25. A tensile spring 42, anchored at one endto end wall 23 and secured at its other end to link 45.

By reason of tensile spring 42, lever 57 is constantly urged towards; the periphery of stationary disc !7,,so that its said lug -48. will entercertain notches provided in the periphery ;of-;disc ll. "One of such notches is designated iBc-and islocated, see Fig. 5, sothat, when upperrberth is in closed position, lug :48-wi1lsnapinto said notch 86, to positively lock the parts in closed position, as shown.

To manipulate, the safetylock (for opening the berth), hand-latch-.2 -5 ispul-led'out, to the-left Fig. 5, thus turning bell-crank lever M counterclockwise and raising lever. 4'], thus withdrawing its lug .48 from notchiBc. ZUpper berthZEi is then turned eoyunuistepped by26-i5 (as described above) in this-positionqof the berth, lug es snaps intoa second notch l8 on the periphery of disc i7 asshown inF igQ. A, third notch Him is, provided in the periphery of disc .llfinto which, lug-48 snaps, when. the upper. berth is in slanted or make-up positionas inFig. 7.

A similar safety lock arrangement is provided on lower berth3ii and manipulated by hand-latch 35, ,Fig. 1, the .partsbeing the same reference numerals as described-andshown with reference to the upper-berth. The only differenceis that the disc ll associated withthelower berth has only two notches, viz, .lSc-andJB, there being no notch for azslanted or makesup position. I

Referring to Fig. 2, flashing [.2 is provided to the rear of the berths, between the side stanchions i9, it. The berths, .such as .upperberth 20, Fig. 2, are provided with rollers [9 which engage said flashing l2.

ReferringtoFig. '7, .the sides of the. berth are provided with rubber bumpers. 37,...3'! whichfcontact rubber bumpers 38,138 which, line the opening in the housing, ,see Fig. 1. I

An equalizing. coil spring,2,.Fig. 8,Iis provided at each trunnion or axis 2!, see;Fig. .6. .As clearly shown in Fig- 8, the inner end of-the coil, spring is'held in a stud or spindle (axis) v2| of upper berthZG, While the other. end ofthe spring. is secured to stanchion. ,Thissecure nent is made adjustable so that the proper. t e,nsion maybefapplied to the coil spring. Forfthis purposa a plate 50, Fig. 8, is held to -stanchionllii,easbymeans..of threaded bolt ea, and provided with,an opening or hook 52. by which theeenduof the spring can be secured. .By turning boltfil thespringanchor 50 may be movedtowards, pr away (from,- the rightside of stanchion l0,,thus-.varying thft sion of .coilspringZ. v

The berth-ladder in itsznormal Knot-meme) position,iis.turned so: that it is.-re.p.0sed horizontallyjalong the-frontof the; upperziberth' 20;;as clearly shown in Fig. 2. To enable it to be sojnmed.

its two sidepieces 60, are pivotally secured to the front of the berth. The details of construction are clearly shown in Figs. 10-11, from which it will be seen that one of the sidepieces, more particularly, 90, is radially aligned with the pivotal point SE of securement to the berth, whereas the other sidepiece i0 is offset or spaced from its pivotal point ll. That is, sidepiece '10 is connected to the pivotal securement by an elbow fitting 72.

The sidepieces 80, 70 may be made tubular and round (cylindrical) but for several reasons, such as strength, beauty of appearance, economy, etc. they are given the oval shape shown in Fig. 13 and hollowed internally by a large central bore 53, 73 and two smaller bores 84, 14. The manner of articulating the sidepieces to the front of the berths, represented by plate 20 in Fig. 12, is shown in that figure with reference to the sidepiece 80. In the central bore 63 at the upper end of sidepiece 30 is securely held the threaded, bolt-like end 85 of a fitting 86. Freely rotatable on bolt end 85 and disposed between the end of sidepiece 60 and a pair of lock nuts 67 is a disc or roller 88. Fitting 66 has a spherical seat 69 for a ball or sphere 59 which projects from a bracket 57 secured to the aforesaid plate 20 of the upper berth. Also secured to the bracket is a cam surface 58 engaged by the disc roller 88. The other sidepiece (0, Figs. 10-11, is similarly articulated, the parts being similarly designated 58-3806.

By reason of the spherical connection 59-68 between the two sidepieces 80, 70 and the upper berth and the provision of cam surfaces 58, 58 and rollers 68, 68, the ladder, more particularly, its sidepieces 60, 70 is extended outwardly away from the wall, when the ladder is being turned to open position, see Fig. 3.

The rungs of the ladder, designated 53, are disposed between sidepieces 60, 10, being articulated at 54, 54 to elbows or lateral projections 55, 56 directed inwardly from sidepieces 80, Ill.

The berth-ladder is held in its folded, non-use position by means of a latch 15, Fig, 13, which is turnably mounted to a bracket 19 secured to the berth, as by the pin 18. Pin 78 may not only turn relative to the bracket 19, but may also be pulled outwardly, together with latch 15, away from the bracket. However, a small compression spring 17 abutting the headed end 18 of the pin, normally maintains the latch 75 in close relation to bracket 79, as shown in Fig. 13, in which position the sidepieces 50, 70 are clamped in position, as shown in Fig. 13. Preparatory to turning the ladder to operative position, the latch 75 is pulled away from bracket 19 (i. e. to the right in Fig. 13), the opening 75 enabling the hand to grasp the latch. The latch is then turned 90 to the position shown in Fig. 3, thus freeing the sidepieces of the ladder.

Upper berth 30 is provided with a protective railing at the head end, i. e., at the right as viewed in Fig. 3. Said protective railing comprises an ell-shaped tube having one leg 80 extending longitudinally, Fig. 3, and its other leg 8| extending transversely, Fig. 4. When the upper berth is turned to closed position, said protective railing is collapsed for folded and becomes erected to protecting position, when the berth is turned to sleeping position, as in Fig. 4, For this reason protective rail 8! is mounted on the berth by a parallel linkage which comprises a pair of supporting arms 82, 83, pivotally mounted on the end wall of the upper berth at 84 and 85 respectively, said arms being distally articulated to the ends of rail 8!, Fig. 4. To one of said arms, more particularly, 82, is articulated one end of the anchorage link 89, the other end of which is pivotally mounted to the berth Wall at 87.

I claim:

1. In a berth installation disposed adjacent a bulkhead, in combination, a pair of stanchions secured to the bulkhead at the spaced distance of the berth, at least one berth disposed between the bulkheads, axially-aligned trunnions for pivotally mounting the berth, a stationary disc disposed on one of said trunnions at one of said stanchions, a lever pivotally mounted at one end wall of the berth having a distal lug engaging the periphery of the disc, said disc periphery having a plurality of notches, spring means for normally urging said lever towards the disc to engage its said lug in said notches, one of said notches being angularly disposed on the disc to lock the berth in closed position, and another of said notches being disposed from said first notch to lock the berth in open sleeping position, manual means for withdrawing said lever lug, said berth adapted to be turned more than 90 from its closed position to an inclined slanted makeup position, said stationary disc having a pcripheral notch to lock said berth in said slanted make-up position, a coil tensile spring disposed at said trunnion, one end of the spring being secured to said trunnion to turn with the berth, the other end of the spring being secured to said stanchion.
