9 Claims.

This invention relates to berth structures and more particularly to the type useful for sleeping cars, boats and small bedrooms.

Shiftable berth structures, as now employed in railway cars, are formed of relatively heavy metal parts so that they will be strong enough to withstand distortion caused in the operation of the car and abuse resulting from movement between stored and prone positions. The weight of such berths is objectionable because of the physical effort required to` move them between stored and prone positions.

It is an object of this invention to provide a relatively light weight metal berth structure constructed in such a manner that it will withstand the distortive forces to which it is sub- J'ected.

Another object of the invention is to strengthen a sheet metal berth pan by the provision of reinforcing means forming a box-like frame around the base portion.

Another object of the invention is to provide reinforcing means for a sheet metal berth pan structure that will prevent distortion and also act as a shelf for the mounting of a false bottom.

Another object of the invention is to provide a hinged sheet metal berth pan with a false bottom detachably secured therein spaced above the bottom of the pan to provide a chamber for the reception of accessories, such as 'mounting pins and latch operating mechanism.

Still another object of the invention resides in the mounting of pivot pins with a sheet metal berth pan structure in which the mounting is formed as a part of marginal walls and a pan reinforcing means within the marginal walls.

Another object of the invention is to provide a mounting for a pivoted berth that can be assembled with the berth and the bearing portion properly located within the walls of the room prior to being anchored thereto.

These and other objects of the invention will be apparent to those skilled in the art from a study of the following description and accompanying drawings, in which:

Figure 1 is a transverse sectional view through a portion of a sleeping car showing the berth structure in stored position.

Figure 2 is a horizontal sectional view through a car room showing the berth structure in prone position.

Figure 3 is an enlarged fragmentary View, partly broken away, of one of the pivotal mountings for the berth.

Figure llis a sectional view in the room showing the berth in side elevation and in pronev position with the seat back attached, the-view being taken substantially on line 4 4 of Figure 2.

Figure 5 is a sectional view of one of the pivotal mountings for the berth taken on line 5-5 of Figure 3.

In the drawings a sleeping car, indicated by numeral i0, has a roof irl, outer side wal-1 I2, aisle wall i3 and floor 64. The space between the side wall and the aisle wall is divided into rooms by longitudinally spaced transversely extending partition walls I4. Walls l5 extend parallel with and adjacent the aisle wall and the outer wall at one end of the room and the ends thereof, toward the center of the room, join with transverse front walls i6 extending to the ceiling 55, the outer car wall and the aisle wall. Walls l5 and i@ provide an alcove Il of slightly more than sufficient size to receive the pivoted berth structure i3 when swung into vertical stored position.

The berth structure is formed of relatively thin metal and has marginal wall means comprising side members i9 and end members 20 preferably formed as aluminum extrusions of similar cross section. rihere is a bottom cover means 2 i, pref 7 erably formed as a metal plate, secured to the base portion of the marginal wall means. The marginal wall members are welded together at their adjacent ends as indicated by numeral 22 and the upper edge is formed with a bead 23 projecting inwardly of the pan. Relatively short flanges 2li are turned inwardly from the base oi' the wall members and the lower marginal portion of the wall members is thickened, as shown in Figure 5 and indicated by numeral. E5. The bottom plate 2l is preferably permanently scoured by welding to the under-face of flanges 2e to form with the marginal walls the berth pan structure.

Reinforcing truss means are provided within the pan and comprise W-shaped angle members 26 substantially coextensive with the wall members and over-lying the flanges 24. The upper leg 2l' of the reinforcing members extends parallel with and is secured to an intermediate portion of the adjacent pan wall, by welding or other suitable means, and the lower leg 23 of such reinforcing members extends horizontally and parallel with bottom plate 2l to which they are permanently secured by suitable means, such as welding. The inner legs 29 of the reinforcing members extend parallel with legs 2l and the adjacent marginal wall member while the inner legs 30 of the reinforcing members extend parallel with the bottom plate and in spaced relation thereabove. Legs 28 and 29 are arranged to extend inwardly beyond the adjacent wall base flanges 24. The legs 3U of the reinforcing members provide a shelf on which a false bottom plate 3l is detachably secured by screws 32.

The marginal walls below legs 2l of the reinforcing members being thickened adds to the strength of the base portion of the pan. The reinforcing members, the thickened lower portions of the marginal walls, anges 24 and base plate 2| form a box-like hollow frame around the base portion of the pan giving it such rigidity that the parts composing the pan can be relatively thin and at the same time provide sufcient strength to prevent distortion of the pan in the normal use of the berth structure in a sleeping car. The bead at the upper edges of the marginal walls provides an inwardly extending over-hang assisting in the retention of the mattress and bed clothes.

The pan structure is further reinforced by transversely extending ribs 33 of inverted V formation, such ribs terminating in legs 3d that are welded to the inner face or" the bottom plate 2i. The pan is further reinforced by angle members 66 welded to the adjacent ends of the reinforcing members. As the bed is mounted to be swung upwardly into alcove Il in stored position, the outer face of base plate 2l is provided with a suitable finish to harmonize with the furniture and interior nish of the room in which it is located.

The reinforcing members 25 in addition to serving to form the box-like frame structure of the pan and providing a shelf on which the false bottom is mounted in spaced relation from the bottom plate, also provides a mounting for pivot pins 35 arranged concentrically adjacent one end of the bed. The legs 25 of the reinforcing niembers adjacent side walls IS of the berth pan are formed with an opening 35 and concentric with such openings there are similar openings Sl formed in the pan side walls, see Figure 5. A reinforcing plate 3S is riveted to the inner face of the side walls I9 and has an opening concentric with openings 35 and 3l. A head 3S is welded or otherwise suitably secured to the inner end of each pin and the pins are assembled with the'pan by moving them axially through openings 36 and 3l until the heads abut the legs il@ of the reinforcing members to which they are detachably secured by screws 4B. This method of assembling the pins with the berth from the interior of the pan is made possible by the removability of the false bottom.

A supporting device 4l for each pin carries a bearing 42 into which the ends of the pins projecting beyond the pan side walls are received. Formed as a part of these devices are face plates 43 having openings dll therein for receiving screws A5. These plates i3 over-lie openings in walls I5 and i6 for accommodating the supporting device 4l. Due to manufacturing inaccuracies, it is extremely difficult to provide drilled holes for the supporting devices so that the bed will be properly located when mounted but with the present construction, the supporting means can be mounted on the projecting ends of the pins, with washers 45 first assembled on the pins adjacent the marginal walls, whereupon the berth can be properly located in its desired pivotal position. After so locating the supporting devices holes can be drilled in walls I6 through openings 44 and the screws 45 then applied to properly secure the supporting devices.

Extending across one end portion of the pan is a detachable strip 55 having depending feet 49 at its ends resting upon the upper surface of the false bottom. These feet are detachably secured to threaded backing members 5l on the underside of the false bottom by screws 52 that pass through the openings in the false bottom. As the strip 5i) is spaced above the false bottom, it provides an anchor for a mattress strap 55.

Referring to Figure 1, a chair seat is indicated by numeral 55 and a chair back is indicated by numeral 56. This back is arranged to be detachably secured to the bottom plate of the pan. Bracket 5l is fixed to the seat back and is secured to the bottom plate of the pan by a wing nut 59. Strap 58 is secured to the base plate by rivets 5t. A hanger El is xed to the upper portion of the seat back and slides under the strap.

The invention may be modified in various respects as will occur to those skilled in the art and the exclusive use of all modifications as come within the scope of the appended claims is contemplated. Y
