Compared with the conventional gable roof type, the improvement rate is 74.5% without the trapezoidal roof type sheet lid, and 72.4 to 66.0% with the sheet lid type, which is about 45%. It can be seen that the blow-up force decreases.

Regarding the windward wind-up force, as shown in the comparison table of windward wind-up force in Fig. 13, the tent blow-up force of the conventional gable roof type is the largest, followed by the trapezoidal roof type (without sheet lid). It can be seen that the tent blowing force for the trapezoidal roof type (with a sheet lid) is the smallest.

In contrast to the conventional gable roof type, which falls (NG) at a wind speed of 1 OmZ s, the trapezoidal roof type (without sheet lid and with sheet lid) falls at a wind speed of 13 m / s. (NG). . Industrial Applicability

According to the present invention, the following effects can be expected.

1. According to the outdoor tent of the present invention, the vertical cross-sectional area of the tent is reduced, so that the wind pressure received by the crosswind is reduced, and an outdoor tent that can cope with a sudden strong crosswind can be realized.

2. According to the crosswind-type outdoor tent of the present invention, since the tent height can be kept low, it is possible to construct a tent with high safety, a long depth, and a large floor area.

3. According to the crosswind-type outdoor tent of the present invention, the tent height can be lowered, so that the use of the outdoor tent in places where there is a structure above the bridge, such as a riverbed, which cannot be used by a normal outdoor tent, is increased. I do. 4. According to the crosswind-type outdoor tent of the present invention, when a gust or strong wind blows into the tent, the ventilation opening formed of one or more holes adjacent to the tent roof and the ventilation opening provided on the side surface. By automatically opening the lid that covers the outer surface, it is possible to prevent the tent from falling or being lifted by gusts or strong winds, thereby reducing the risk of harm to people.

5. In the case of a crosswind-compatible outdoor tent in which the left and right edges of the lid of the ventilation opening are fixed to the awning via a waterproof sheet that is made to be stretchable by folds, when the ventilation opening is open, The inflow of rainwater can be prevented.

6.Because the tension of the awning portion left between the holes keeps the shape of the awning, the awning near the ventilation opening does not cause any inconvenience such as hanging down, and it is installed on the outer surface of the ventilation opening. The fall of the lid into the tent can be prevented.
