DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inflatable air tent.

[0002]

2. Description of the Related Art A conventional air inflatable air tent has a structure in which a vertical air column, a horizontal air column, and a tent forming a skeleton are made of a rubber cloth or a rubber sheet.

[0003]

The conventional inflatable air tent made of a rubber cloth and a rubber sheet is heavy, and requires time and a large number of people to carry, assemble and fold. In addition, since the air column and the tent are equipped with a gas release mechanism, the use of the octopus system for charging and exhausting air makes it possible to release air in a short time, but it is difficult to release air from the entire tent. In addition, it takes time to fold and, at the same time, an air pocket is generated, which swells almost four times in length (2) × width (2), and requires a bulky and large storage bag. In addition, the bonding method using an adhesive requires a wide portion at the bonding portion, which has spurred an increase in weight. Furthermore, if foreign substances enter the air safety valves provided for the multiple vertical and horizontal air columns, or if the ropes inside the air columns are sucked into the safety valves, the normal function of the air safety valves may not be maintained. Was.

[0004]

An air tent according to the present invention.
Are the vertical columns and the horizontal columns that form the skeleton.
The tent is made of a synthetic resin sheet. Then, the vertical air column, the horizontal air column, and the awning, which become the synthetic resin sheet, are subjected to high frequency fusion at an arbitrary bonded portion.

It is preferable that the vertical air column, the plurality of horizontal air columns, and the awning are formed using a sheet made of a thermoplastic polyurethane synthetic resin.

In addition, a plurality of air leak holes are provided in the inclined portion around the ceiling of the awning, and an air leak cover portion having a diameter two to three times the diameter of the air leak holes is provided below the rainwater flow direction. An air escape device having a non-adhesion portion of 10 to 40% of the circumference of the air escape adhesion portion is provided.

Further, a fiber net cloth is fixedly installed at the air passage opening of each air safety valve attached to the vertical air column and the horizontal air column.

In addition, a fiber mesh cloth is provided around the air passage to promote air supply by eliminating foreign matter from entering the gap between the fixed part of the air safety valve and the butterfly when supplying air to the vertical and horizontal air columns of the air tent. And eliminate supply over air.

[0030]

The air tent of the present invention is made by using a synthetic resin sheet instead of the conventional rubber-coated cloth air tent. Due to the fusion, the bonding area was small and labor for setting up and storing was saved. In addition, air leakage was reduced as compared with the bonding method, and maintenance of the air tent was facilitated. In addition, a plurality of air leaks are provided around the ceiling of the awning, which makes it possible to save time and effort for folding. In addition, a plurality of air safety valves are attached to the vertical air column and the horizontal air column, and a fiber mesh cloth that prevents foreign matter from entering the air column inside the air passage opening is subjected to high frequency fusion, so that the bonding area is small. In addition, it is thin and has no air permeability at the bonding portion, so that waste of air supply can be eliminated.
