No. 791,431 Claims priority, application Japan, Jan. 16, 1968, 43/ 1,928 Int. Cl. F41h /08 U.S. Cl. 109-495 3 Claims ABSTRACT OF THE DISCLOSURE A shelter for military use consists of a dome having a protecting brim integrally formed therewith at the front side, and a skirt integrally formed therewith at the back side and spread around the substantially half periphery thereof.

BACKGROUND OF THE INVENTION This invention relates to a shelter for military use and more particularly to a transportable shelter used in covering a pit or trench in the battle field so as to provide a simple fortified place.

There has been known a fort built of a dome-shaped concrete block as a tochka. Such fort was conveniently available for a stationary hostile action. But where fighting was carried out from place to place, the fort was of no use, because its construction required large amounts of time and labor.

SUMMARY OF THE INVENTION An object of this invention is to provide a fort conveniently available, even in the case fighting is carried out from place to place.

Therefore, there is developed a transportable shelter used in covering a pit or trench in the battle field so as to form a simple fortified place. Said shelter consists of a dome having a protecting brim integrally formed therewith at the front side, and a skirt integrally formed therewith at the back side and spread around the substantially half periphery thereof.

Said shelter should be strong enough to endure the load of sandbags placed thereon, and light enough easily to be carried by a suitable number of fighters. Accordingly, said shelter is preferably made of reinforced plastic materials.

3,521,580 Patented July 21, 1970 ice FIGS. 1 to 3 indicate a transportable shelter for military use embodying this invention. The shelter consists of a dome 1 having a protecting brim 2 and a skirt 3. Said brim is integrally formed with said dome at the front side and spread around the substantially half periphery thereof. Said skirt is integrally formed with said dome at the back side and spread around the remaining substantially half periphery thereof. Said brim 2 is positioned at a higher level than the peripheral edge of the skirt 3, whereby an opening is so formed at the front side as to afford a full sight for the fighter, in the case where the shelter is placed on the ground in a manner to cover a pit or trench 4 as shown in FIGS. 4 and 5.

Said shelter preferably involves a plurality of creases 5 formed thereon so as sufficiently to prevent sandbags 6 or a bulk of earth and sand 7 to slip down therefrom as shown in FIGS. 4 and 5, as well as to reinforce said shelter.

Said shelter is preferably made of such reinforced plastic materials formed by the steps of closely attaching a sheet of glass fabric to the inner surface of a mold which negatively forms the configuration of said shelter, coating said fabric with a body of liquid synthetic resin for impregnation, and repeating said steps until a product attains a suitable thickness, followed by heating said product for solidification.

The shelter made of said reinforced plastics is strong enough to endure the load of sandbags placed thereon, and light enough easily to be carried by a suitable number of fighters.

Consequently, the shelter can defend the fighters from being exposed to weather as well as to the enemys bullets. The sandbags and a bulk of earth and sand placed on the shelter are conveniently available in protecting the fighters from the enemys bombs or grenades.

Spacers 8 made of elastic material such as rubber have an aperture formed through the center thereof. Said spacers 8 are attached to the upper surface of the shelter by means of bolt and nut 9 to that of a plurality of shelters can be superposed in a stable condition when they are not employed.

Each embodiment indicated in FIGS. 6 to 11 has a different configuration and size from that of FIGS. 1 to 3. Such kinds of shelters will be selected in accordance with the conditions in which they are employed.

What is claimed is:

1. A shelter for military use consisting of a dome having a protecting brim integrally formed therewith at the front side, and a skirt integrally formed therewith at the back side and spread around the substantially half periphery thereof.

2. The shelter for military use claimed in claim 1 in which a plurality of creases are formed on the shelter.

3. The shelter for military use claimed in claim 1 in which said shelter is made of reinforced plastic materials.
