Description

United States Patent PATENTE-IU 1m28 um SHEET 3 UF 6 PTENTED DEC28 197i SHEET 5 UF 6 i y #1910 JA.
PORTABLE FOLDABLE SHELTER BACKGROUND OF THE INVENTION It has been the common practice when providing troop shelters to build shelters that are somewhat permanent in nature, though they may be called portable shelters. However, the need for relocation and mobility in limited warfare situations requires lightweight, highly mobile shelters. Experience has proven that troops living in an austere situation will continue to elevate their standard of living utilizing any free time available. A design which would avoid this environmental deficiency would make more man-hours available to be devoted to the assigned tasks.
BRIEF SUMMARY OF THE INVENTION According to this invention a lightweight 100 percent recoverable portable shelter which may be stored in storage container 3X8 I3Xfeet expands into a shelter 8 I3X33 feet. A novel folding pattern for the wall and roof of an accordion type structure permits the walls and roof to fold in a 180 configuration for storage to leave about 160 cubic feet of storage area for personal gear such as cots, pillows and other gear. Folding end walls and floor members unfold from the sides of the storage container. Foldable roof support beams are secured to the center structure and end walls. The accordion wall and roof structure is secured to the center structure, floor and end walls with special type seals.

DETAILED DESCRIPTION OF THE INVENTION Reference is now made to FIGS. l and 2 of the drawing which shows a shelter l0 having a central storage section 12, a pair of end wall sections 14, a pair ofexpansible roofmembers l5 and wall sections 16, roof support beams 18 and a pair of floor sections 20. When the shelter is packed for movement, the roof and wall sections l5 and 16, support beams I8, floor sections 20 and end walls 14 are stored in the central storage section l2, as shown in FIG. 3.
The roof and wall members l5 and 16 are made by scoring a plastic-coated polyurethane foam board in the pattern shown in FIG. 4 in the manner shown in FIG. 5, wherein die blocks 22 provide a double indentation to form a folded configuration as shown in FIG. 6. The positive folds are shown as broken lines 23 and the negative folds are shown as dotted lines 24. The juncture of the roof and wall sections shown generally at 2S, in FIG. 1, has positive folds 23' forming inverted approximately angles and the portion 24" between the vertices having an opposite fold to the fold 23 outside the vertices. Also portion 23" has the opposite fold to the fold portion 24 outside the juncture section. This fold configuration permits a fold ofthe wall sections 16.
Bottom flaps 27 and 28 are taped together to form a substantially straight line edge for attachment to the floor member, as will be explained later.
Hinges 26 connect the floor sections to the central section and end wall and the two parts of the floor section together so that the floor and end walls fold out from the center storage section 12, in the manner shown in FIGS. 7 and 8.
Jacks 30 are attached to floor studs 29, as shown in FIGS. 9 and l0. The jacks 30 are used to level the floor. A latch mechanism for securing the floor members 20 in storage section I2 is shown at 19.
Foldable beams 18, shown in greater detail in FIGS. l1 and I2, are hinged at 3l with the ends brought together and secured by tumable hooks 32 which engage pins 33. The ends 34 of beam 18 are secured to end wall 14 in the manner shown in FIG. 13. At the storage section end, flange 36, as shown in FIG. I4, fits into the end 35 of beam I8, shown in FIG. l5. The beams from one side of the shelter are placed in hangers 38 until the other side of the shelter is erected. The ends 35 are placed on flanges 36, when both sides of the shelter have been erected, and the ends are secured by latches 39, as shown in FIG. 16.
The roof l5 and walls 16 are stored in the position shown in FIG. 17. Straps 42 and 43 pass through loops 45 attached to the central storage container l2 and support the folded roof and wall sections l5 and 16. Folded beams 18 are supported on flanges 47 within the container l2. Items shown schematically at 49, such as tool kits may be stored on the beams 18. Also the jacks may be stored on beams 18 and may be taken out through access door 2l. The compartment 5l below the beam may be used for personal items such as beds. Other items, such as exhaust fan 53, may also be located in the storage compartment 51.
After the support beams are in place, the roof and wall section is extended as shown in FIG. I9. The roof is secured to the center section, as at S5, in FIG. 20. A flysheet 57 is secured to flange 58 by a fastener 60 to form a weather seal between the roof and the container. Similar weather seals are provided by means of flysheets 62, flanges 63 and fasteners 64 between the roof and wall and the end wall as shown in FIG. 2l. Also, a similar seal is provided between the wall I6 and the center container. The wall I6 is secured to the floor by means of flysheets 66, flanges 67 and fasteners 68 as shown in FIG. 22. The roof 15 is then secured to beams 18 by means of straps 37, shown in FIG. l5.
The wall of the central section, floor, and end wall are made of conventional honeycomb material to reduce the weight; however, other lightweight material could be used.
Though the end walls have been described as hinged to the floor members, in some applications the end walls can be separate from the floor'members.
Means other than jacks can be used for leveling, for example, adjustable floor pads.
There is thus provided a lightweight, easily constructed, 100 percent recoverable shelter that can be erected in about 4 man-hours and which stores in a compact storage container.
