Abstract

PURPOSE:To provide an air expansion type air tent which is easy in carrying, assembling and folding by forming the skeleton of a roof section of a plurality of vertical columns and a plurality of lateral columns crossing the vertical columns at right angles, covering the vertical column, the lateral column and the roof section with a synthetic resin sheet, and providing a plurality of air leaking devices on the periphery of a ceiling section. CONSTITUTION:The skeleton of a roof section is formed of a plurality of vertical columns 2 and a plurality of lateral columns 3 crossing the vertical columns 2 at right angles. The vertical column 2, the latral column 3 and the roof section are covered with a cloth coated by thermoplastic polyurethane resin. In addition, a plurality of tent pneumatic check valves 28 are provided in the ceiling peripheral part 30 of a tent at equal intervals to leak air at the time of folding the tent. The check valve is tray-shaped, and has the inside diameter of a lower disc part 28d being smaller than the outside diameter of the upper edge periphery 28c of the tent pneumatic check valve and an oblique part 28b. In the adhesin section 28a of the check valve 28, about half of the upper part of the oblique part of the tent adheres to the check valve adhering part 29 of the tent, and the lower part of the tent oblique part of the check valve 28 is not applied with adhesives. Thus an air expansion type air tent which is easy in carrying, assembling and folding can be obtained.

Description

Detailed Description of the Invention

[0001]

[Field of Industrial Application] The present invention relates to an air inflatable air tent.

[0002]

2. Description of the Related Art In a conventional air-inflatable tent, a vertical air column, a horizontal air column, and a roof member that covers the skeleton are made of rubberized cloth or a rubber sheet.

[0003]

The conventional air inflatable air tent made of rubberized cloth or rubber sheet has the following drawbacks. 1) It was heavy and required time and a lot of manpower for carrying, assembling and folding. 2) It takes a long time to fold, and at the same time air pockets occur, making it bulky and making a large storage bag.
Was needed.

[0004]

In order to solve the above problems, the present invention has been achieved as a result of intensive research, that is, the present invention comprises a plurality of vertical air columns and a plurality of vertical air columns which intersect at right angles. The vertical air column, the horizontal air column, and the roof part are covered with a synthetic resin sheet to form a skeleton of the roof with the horizontal air column of In addition, in an air tent in which the horizontal air column and the roof part are made of synthetic resin sheets, a plurality of air escape devices are provided around the ceiling part, and one of the air escape devices of the air tent is a check valve. In addition, an air leak hole of 5 to 10 cm is opened in the inclined portion around the ceiling of the air tent, and a synthetic resin sheet having a diameter of 2 to 3 times is provided around the air leak port in the rainwater flow direction. The non-adhesive portion of 10-40% of the circumference is provided in the lower part of the An air 逃漏 device air tent.

FIG. 1 is an assembled perspective view of an air inflatable air tent according to the present invention. The features of the air inflatable air tent of the present invention are listed as follows: 1) Since high-strength polyamide fiber and thermoplastic polyurethane resin are used for the main body material, weather resistance, ozone resistance,
It has excellent wear resistance and self-extinguishing properties. 2) Since the thermoplastic polyurethane resin cloth is used, it is possible to make it 30% or more lighter than the conventional rubber cloth. 3) Appropriate air column The pressure is high, so the rigidity is strong and the stability of the tent is good. 4) Since the safety valve 10 is attached to each air column, it is safe because the air column is not filled with a pressure higher than the specified pressure. 5) The front and rear, right and left sides of the tent are hoisted, so you can enter and leave freely. 6) A plurality of tents can be connected by the connecting mechanism attached to the entrance / exit. 7) Equipped with an anchor rope (not shown) and a water baffle 23 to hold the tent
Therefore, it is stable even in strong winds. 8) Suspending hooks (which can move in any direction, not shown) are attached to various places inside the tent, so it is possible to take in electric wires, ventilation holes, etc. 9) Since the side of the tent has an inlet (not shown), it is possible to take in electric wires, ventilation holes, etc. 10) New charge / exhaust device Octopus system (not shown)
This allows a small number of people to deploy in a short time. 11) The air column and tent are equipped with a gas venting function, and it is possible to vent air in a short time by using the new octopus system, which is a replenishment / exhaust system, but it is difficult to vent the entire tent.

FIG. 2 is a perspective view of the framework of the vertical and horizontal air columns of the air inflatable air tent of the present invention.

FIG. 3 is a perspective view of the awning air check valve 28 of the present invention. The use of the awning air check valve in the present invention is effective when an octopus system (not shown) is used as the air vent for the air column, but when the awning is folded, an air trap (not shown) is generated. Vertical (2) x Horizontal (2)
It swells up to 4 times. In order to escape the air when folded, a plurality of awning air check valves 2 should be provided in the peripheral portion 30 of the awning ceiling.
By arranging 8 at equal intervals, it has succeeded in letting air escape during folding. The check valve is a tray type, and the lower disk portion 28d is larger than the outer diameter of the upper peripheral portion 28c of the awning air check valve.
Has a small inner diameter and has an inclined portion 28b. Check valve 2
In the adhesive portion 28a of FIG. 8, about half of the upper portion of the inclined portion (not shown) of the awning is attached to the check valve adhesive portion 29 of the awning, and the lower portion of the awning inclined portion of the awning air check valve 28 is coated with adhesive. Do not consist of non-bonded parts.

FIG. 5 is a plan view showing an air leakage method without using the air check valve of the present invention. A plurality of air escape ports 31 are cut out around the ceiling of the awning 1, and the air escape port covering portions 32 are formed in the form of covering the air escape ports 10 to 40 at a lower portion of the awning inclined portion of the air escape port. % Non-adhesive air escape portion 31
a is provided.

If the air escape port is 5 cm or less, it is necessary to provide an innumerable number of air escape ports, and if it is 10 cm or more, there is backflow of rainwater, which is not desirable. 10% of the air escape part of the air escape port
In the following, there is no backflow of rainwater, but there is a drawback that it takes a long time to release air when folding. When it exceeds 40%, backflow of rainwater occurs.

FIG. 6 shows an air bleeding promotion method in the case where air bleeding portions are in close contact with each other in FIG. 5 and air bleeding is insufficient. An open cell body, through which air can flow freely, is fixed to the air escape portion to prevent close contact.

[0011]

[Operation] Multiple air check valves are provided around the ceiling of the awning in order to eliminate air traps when the air tent is folded and facilitate air bleeding, and air escape ports are provided separately from the check valves. By providing the air leakage cover portion excluding the leakage portion, water leakage from rainwater can be prevented, and at the same time, generation of an air pool during folding can be eliminated.

[0012]

EFFECTS OF THE INVENTION Instead of the air of the conventional rubberized cloth, the air tent is made by using the synthetic resin sheet, so that the labor for the construction can be saved. In addition, multiple check valves and air leaks are provided around the ceiling of the awning, making it possible to save the trouble of folding.
