13 Claims.

The present invention relates to buildings which can be knocked down for convenient manufacture and.transportation and which are particularly adapted to shelter human beings.

An object of our invention is to provide a building which may be insulated so as to be suitable for shelter in very cold or very. warm climates and to provide, if desired, a suitably'insulated floor for this purpose.-

Another object of our invention is to provide a building of the class which i light and can be knocked down so as to occupy minimum space for convenient transportation either by truck, railroad, vessel or transport plane.

A still further object of our invention is to provide a building which can'be quickly erected and knocked. down by a limited number of unskilled persons so it is particularly adapted for the use of the armed forces.

An object of our invention is to provide a building of the class which issuitable for emergency Red Cross use or for living quarters.

Generally stated, the objects of our invention are to provide a buildin which can be manufactured at low cost in mass production, is simple and pleasing in appearance.

Another object of our invention is to provide a structure which can be efliciently and cheaply anchored tothe ground.

To these and other useful ends, our invention consist of parts, combinations of parts, or their equivalents, as hereinafter set forth and claimed 1 and shown in the accompanying drawings in which: I r

As thus illustrated, the coverings of our improved building are designated in their entireties by reference characters A. The front wall of the building is designated in its entirety by reference character B. The rear wall of the building is designated in its entirety by reference character C. The main ribs in their entirety are designated by reference character D and the supplemental ribs are designated in their entirety by reference character E. The floor sections in their entirety are designated by reference character F. The side base panels or sills are designated in their entireties by reference characters G and the end base sills are designated in their entireties by reference character H.

Members F comprise plywood sections Ill, Gen erally it requires four or eight of these members side sills so they may be easily packed with the other parts of the-building. For the building illustratd in Figures 1 and 2, eight of these members are required. In this building, it will be *noted that three main ri-bs D and two supplemental ribs E are required. ,In the frame shown in Figure 4, three main and foursupplemental ribs are required.

Sills or floor boards G comprise preferably plywood panels I I having preferably at the outer top edge a half round stiffening strip l2 and secured to its bottom inside edge a stiffening strip l3 which may be either plywood or integral strips of wood.

Members II and I3 are secured together by bolts. Sills H are similar to sills G except as to length and having the same'part numbers H and I3. On the outside of each sill G and H-we mount a number of spaced hooks ll, the purpose of which will hereinafter-appear. Members I are mounted on; frames comprising sills l5 which extend around the edge of these members and preferably other sills it which extend across the center of member F longitudinally with the building".

When sills l6 and I6 are attached to members In, waterproof fabric pieces H are secured at their edges between the sills and members l0. These the floor assembly as illustrated in Figures 11 and 12. v

Members G and H are provided with spaced hook brackets each having a ring 26 which is adapted to fit loosely over stakes 21 which are pointed at their bottom ends and reinforced at their tops by means of ferrule 28. Posts 21 are each provided with a number of cut-away slots 29, the stake, when being driven, extending loosely through rings 26.

At the proper time, ring 26 is permitted to drop into one of slots 29 in the stake and the stake further driven into the ground so as to hold members G and H firmly on the ground and against members F. Clearly members G and H will be caused to hug the ground and tightly contact the outside edges of members F.

Members D comprise preferably three laminated members 30 (see Figures 3, 4, 6 and 9) having strips 3| on opposite sides thereof. Members 30 are secured together by means of pairs of hinges 33, as illustrated in Figures 3, 6 and 7.

Che hinge of each pair of hinges is provided with a removable pin 34 which is preferably secured to the hinge by means of a chain 35 so pins 34 may be removed and the three members of the ribs folded as illustrated in Figures 6 and 7. When members 30 are unfolded and pins 34 placed into position, the ribs will be rigid as if made integral.

Members E are similarly secured together by means of a number ofvpairs of hinges, members E however, being considerable narrower than members D, as illustrated in Figure 10.

After ribs D and E are made rigid, as already described, their ends are preferably secured to members G, as illustrated in Figure 12, members E being preferably detachably secured to member G as illustrated in Figure 11, wherein two spaced brackets 36 (one not shown) are secured to members G so they contact members E. Members 36 are provided with L-extensions 3'! and U-strips 38 which are hinged to members 31 as at 39. Clearly when the building is knocked down, members 38 may be folded so as to save space.

Members D may be secured to members G, as illustrated in Figure 11 wherein brackets 40 (one not shown) are secured to members G so they fit snugly on opposite sides of members D and having slots 4| forthe reception of bolts 42; thus when member D is. in position, these bolts may be made taut and the assembly made rigid.

' After members D and E are secured to members G, three or more spacing strips 43 are detachably secured to these members in any convenient manner whereby the ribs are suitably spaced for their length and the assembly made rigid for mounting members A thereon.

As illustrated in Figures 3, 4 and 12, the frame of our building will be suitably held to the ground and made rigid. After the, frame has been assembled as described, members A are mounted thereon. These members comprise preferably an outer water proof fabric member and an inner water proof fabric member 5|. These members are formed as shown in Figure 15 for the reception of insulating material 52, the portion inclosing the insulating material being adapted to lie between two members D having spaced wood strips 53 which are preferably tacked to fabric 5|, as illustrated, the ends adapted to lie on members 3| as illustrated in Figure 10.

The edges of members 5| extend outwardly as at 49 and are stitched to member 50 as at 48. Insulating material 52 is stitch mounted to a fabric piece 41 as at 46 and corners are formed in member 5| by stitching as at 45. Members 50 extend past member 49 so as to form flaps 54 which are folded at their edges in any suitable manner around ropes 55. Members A on their longitudinal centers lie on the outer surface of members E; thus to prevent the coverings from sagging.

Member B is formed somewhat similar to members A having an inner fabric member 56 and an outer fabric member 51, having stiffening ribs 58 which are preferably spaced horizontally, the upper end lying on the outer surface of end member D and the lower end (not shown) lying against the upper edge of member H. Members 56 and 51 are stitched together as at 59, forming flaps 60, the outer edge having a rope 6|. The shape of member B is such whereby the fiap will lie over member D when the rope is pulled taut, as illustrated in Figure 10.

Member C is similar to member B. The bottom edges of members A, B and C are folded and have spaced grommets 65 (see Figures 1, 2, 11 and 12) through which ropes 66 extend and are laced under hooks l4 and 25 and made taut as illustrated in Figures 1 and 2, the ends being preferably anchored to stakes 21. It will be seen that members A. B and C will be stretched tightly, their flaps 54 and 60 lying over the outer edges of member D (see Figure 10) and tightly against members |2 so as to make an air tight inclosure. Ropes and 6| are, at their ends, preferably also anchored to stakes 21.

We provide preferably a door Ill in member B,

I the frame ll of the door being suitably shaped so as to lie against an offset in the door jamb '12. The edges of member 13 are folded as at 13 and being covered preferably by means of half round strips I4 which are nailed to member 12, as illustrated. Door 10 is preferably supplied with a window I5 and a ventilating grille 16 is ositioned in the top of member B as illustrated in Figure 1.

We provide preferably a somewhat wider door 80 for member C having a window 8|. This door is preferably hinged to the door jamb as at 82. Member 80 is preferably formed similar to member C wherein the structure extends to and over the top of the building as illustrated in Figure 10.

Stiifening ribs 58 terminate below the horizontal plane of the axis of hinges 82 so the structure of the door will bend in conformity to these hinges. It is desired to use the door when open as a shelter or canopy and the door is made wide so automobiles and the like may be driven into the shelter. .The sides of the door are provided with door jambs similar to jambs 12 shown in Figure 13.

As illustrated in Figure 10, members D and E are preferably laminated and clearly when the building is completely assembled, because of the flaps onmembers A, B and C and ropes 55 and BI the building will be practically air tight.

Strips I! (see Figure 11) are provided as stiffeners for members G and H and also a curved surface around which members A, B and C may be stretched tightly, After the building has tion, we claim:

been assembled, it is the custom to dig a small trench fl'ooriofthe building. V

In Figureb we illustrate a bundle made up from i all of the parts of a complete building. It will 'be seen that the blankets may be rolled into compact bundles. Members E, D, G, H and F may be stacked as illustrated or several bundles made of a shelter.

It will be understood .that any desired. shape and size of door may be provided in members LB and C. 'When door" is used, frame ll co- .operates with the plywood members to stiffen the structure so the doormay be hinge supported.- When door 80 is used in member C, the side frame I members of the door shown'in Figure 4 terminate slightly below the'horizontal plane of the axis of hinges 82, the door thus-formed having a door frame which rests on the door jamb as illustrated.

It will be-se'en that as long as the stakes are in position and ropes 55, El and 66 are firmly" anchored tothe ground, the building will remain practically air tight and will withstand severe stormswithout danger'of becoming dislodged or damaged.

From, the foregoing, it will be seen'that our improved shelter may be quickly erected by a limited number of unskilled men without the use of tools of any kind except for driving the stakes in the ground and the building may be knocked down quickly without the use of special tools.

It will also be'noted that while the building is suitably insulated and strong, it is not heavy and is particularly suited for army use in any territory and under any weather conditions.
