DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inflatable house in which an awning extends when an air is filled to form an arch-shaped skeleton, and more particularly to an inflatable house configured to have anti-wind drag. .

[0002]

2. Description of the Related Art Conventionally, an inflatable house is constructed by assembling a plurality of arched vertical air columns which are to be inflated cylinders, and a plurality of horizontal air columns connected horizontally between the vertical air columns. It is generally well known that a tent having a mountain-shaped top surface, left and right side surfaces and front and rear surface portions is integrally attached so as to cover the entire skeleton, and the vertical air column is integrally formed on a ground sheet. Have been. The inflatable house is used in a wide range of fields because it can be easily transported and set up and can be easily folded and stored.

In a full landfill system at a waste landfill site, a roof is installed in the landfill to prevent an increase in the amount of leachate in the landfill. Is designed in the form of an expensive tent called a framed membrane structure in order to provide wind resistance against wind, and because the landfill is divided into many sections, the roof is formed to cover one section. Are designed to be able to move to the next adjacent section when the landfill section is full.

[0004] However, the former inflatable house (hereinafter referred to as "house") is not only rigid but not rigid in the arch-shaped skeleton supporting the awning, even if it is easy and convenient to transport, set up or fold and store it. Since the ground sheet laid on the ground is only anchored with an anchor, the basic strength of the house in the installed state is extremely weak. For this reason, the inflatable house has a low resistance to strong winds, and therefore may not be able to maintain the shape of the house under strong winds.In addition, there is a concern that the house may be blown off in the event of a gust of wind. Was.

[0005] The roof installed in the latter landfill site, even if it has wind resistance, is not only an extremely expensive facility, but also requires several days to move to an adjacent section. Must. Therefore, the use of an inflatable house that expands and expands when filled with air is being studied.
As described above, this air-inflatable house has an extremely poor resistance to strong winds, and is considered to be unsuitable for use in places where strong winds are constantly blowing, such as landfills. .

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object thereof is to form a large number of ventilation holes in front, rear, left and right sides of a house. At the same time, a bellows-type telescopic cylinder is provided inside the house at the ventilation opening to reduce the force applied to each surface, and to provide an inflatable house having a resistance to positive pressure and negative pressure received by the house under strong wind. is there.

[0007]

In order to achieve the above-mentioned object, an air-inflatable house according to the present invention comprises an arch-shaped vertical air column comprising an air-inflation chamber and a horizontal column connected between the vertical air columns. In an air inflatable house having a skeleton that forms a skeleton from an air column and covers the entire top surface and four side surfaces of the skeleton, the tent is provided at an arbitrary position between a left side portion, a right side portion, a front portion, and a rear portion. A large number of vents are drilled in each of these, and a bellows type telescopic tube with a mesh bag at the tip inside the awning is attached to these vents, and a depression angle opening is formed between the tent and the outside of the awning. A flap is provided to cover each of the vents so as to have a one-way ridge shape.

The flap is formed by biasing the left and right sides of the trapezoidal sheet symmetrically at a predetermined angle from an airtight cloth, and extending the lower side of the trapezoidal sheet along the inner periphery of a U-shaped frame formed from a rubber or synthetic resin foam. An opening that is fixed and a part of the awning is used as a base cloth, the left and right sides and the upper side of the trapezoidal sheet are attached to the awning, and both ends of the shape-retaining frame are attached to the awning. It is preferable that each of the vents is provided so as to have a single flow ridge shape and cover each vent from the outer surface of the awning.

Preferably, a mesh cloth is attached to the surface of the opening surrounded by the shape-retaining frame and the awning.

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of an air inflatable house according to the present invention, and FIG. 2 is a perspective view showing the inside of the house with a front portion of an awning partially cut away. 1 are arranged at predetermined intervals, and a skeleton 3 is formed by horizontally connecting the horizontally-long air columns 2 to be straight, at the ridge portion and the cross section between the vertical air columns 1,
The skeleton 3 is provided with an awning 4 having a mountain-shaped top surface portion 4a, a left side surface portion 4b, a right side surface portion 4c, a front surface portion 4d, and a rear surface portion 4e. A door cloth 5 serving as an entrance is provided on the front part 4d and the rear part 4e of the awning 4.
Are openably and closably provided by a fastener 6 such as a slide fastener, and the left and right lower ends of the plurality of vertical air columns 1 are fixedly mounted on band-like base cloths 7 and 7 via a fastener 8 such as a fastener. The ground sheet 9 is detachably installed. The vertical air column 1 and the horizontal air column 2 are formed as air expansion chambers by a flexible airtight cloth such as a rubberized cloth or a thermoplastic synthetic resin processed cloth.

In the present invention, the awning 4 is provided with a large number of ventilation holes 10 at arbitrary positions on the left side surface 4b, the right side surface 4c, the front surface 4d, and the back surface 4e. The telescopic cylinder 11 is connected and installed inside the awning 4, and the respective ventilation holes 10 are connected from the outer surface of the awning 4.
And a flap 12 is provided to cover the flap.

As shown in FIGS. 3 and 4, the telescopic cylinder 11 is formed in a bellows shape with an airtight cloth or a synthetic resin or rubber. A mesh cloth bag 13 is provided at the end of the cylinder to form a duct.

As shown in FIGS. 3 and 4, the flap 12 is formed into a U-shaped trapezoidal frame 15 in which the lower side of a trapezoidal sheet 14 cut from a hermetic cloth into right and left sides symmetrically at a predetermined angle and cut into a U shape. The flap 12 is attached to the awning 4 at a position covering the ventilation holes 10 with the upper side and the left and right sides of the trapezoidal sheet 14 at a position covering the ventilation holes 10. Attachment margins 16 at both ends of the shape retaining frame 15 are attached to the awning 4 to form an opening 17 opening between the awning 4 and the shape retaining frame 16 in the depression angle direction as shown in FIGS. The trapezoidal sheet 14 is installed so as to exhibit a one-sided ridge shape by the inclined sides on the left and right sides, and is formed by attaching a mesh cloth 18 to the surface of the opening 17 surrounded by the shape retaining frame 15 and the awning 4. So that each vent 10 is covered from the outer surface of the tent 4 Install. The shape retaining frame 15
Is formed of a foam of rubber or synthetic resin, is folded together when the house H is housed, recovers the U-shape at the time of molding together with the expansion of the house H, and forms the awning 4 and the shape-retaining frame 15 together. It is preferable to form the opening portion 17 that opens in the depression angle direction by itself and surely, and to form the one-way ridge-like flap 12 with the trapezoidal sheet 14. In FIG. 4, reference numerals 19, 20, 21 and 22 indicate an adhesive layer or a welding layer.

The house H of the present invention having the above-described structure.
Is transported in a folded state, and when the storage is released and air is injected, the skeleton 3 is formed and the awning 4 is expanded. The flap 12 forms an opening 17 between the awning 4 and the shape-retaining frame 15 and is formed in a one-way ridge shape with the trapezoidal sheet 14 to ensure the ventilation of each ventilation opening 10.

When the house H according to the present invention is exposed to a strong wind and receives a positive pressure on the flap 12, air enters the room of the house H through the opening 17 and the wind passing through the vent 10 is When the vehicle passes through the telescopic cylinder 11 and the mesh cloth bag 13 and enters the room, the air is buffered and soft. tent
The force applied to each of the left and right side surfaces 4b and 4c and the front and rear surfaces 4d and 4e is reduced.

The flap 12, which is formed in the shape of a one-way ridge and opens in the depression direction, not only prevents the invasion of rain blasted by strong winds, but also has a resistance to negative pressure generated when the wind blows up. Can be

The shape retaining frame 15 in which the opening 17 is shielded by the mesh cloth 18 not only allows the opening 17 and the flap 15 to be formed by itself when the house H is extended, but also causes a negative pressure to act on the flap 15. Then, the flap 15 is prevented from being caught in the vent 10.

The telescopic cylinder 11 provided on the indoor side prevents the house H from being folded and stored.
Numeral 1 acts to reduce the flow rate by extending in a straight shape. Also,
When the opening 17 receives a negative pressure that often occurs when the opening 17 is blown up by the wind, since the telescopic cylinder 11 is always kept at a predetermined diameter, the outdoor air is introduced into the room from the other opening 17. Opening 1 which was taken in and received negative pressure
7, the air in the room can be kept fresh.

Further, since the ground sheet 9 is detachable, the ground sheet 9 is detached and the bottom surface is released, so that the ground sheet 9 can be used as a roof of a waste landfill. When the ground sheet 9 is detached and used, the left and right base cloths 7a and 7b are connected by connecting members (not shown) such as a band plate and a rope to open both sides of the vertical air column 1 when the floor surface is released. The outward opening stress is regulated.

In the air inflatable house having the shape and structure shown in FIG. 1, both the case where the vent and the telescopic tube of the present invention are not provided and the case where the vent and the telescopic tube are provided are used to control the wind speed. As a result of testing the anti-wind drag in a strong wind of about 15 m / sec, the former was unable to maintain its shape due to the wind, whereas the latter was relatively stable and worked in the house. The deformation of the shape was not so great as to cause trouble.

[0021]

The air inflatable house of the present invention having the above-described structure is provided with a large number of vents on the front, rear, left and right sides of the tent, and these vents are provided with rubber or synthetic resin on the outdoor side. A flap that opens with a shape-retaining frame made of foam is provided, and a bellows-type telescopic cylinder is provided on the indoor side. From then on, it is taken into a mesh cloth bag and always into a telescopic cylinder that keeps a predetermined diameter and discharged outside the room.Moreover, since each ventilation port performs an independent suction and exhaust function here, complicated when strong wind blows It has excellent wind resistance against a smooth air flow. Further, transportation, installation, and movement can be easily performed. Therefore, there is an effect that the utility value is large as a temporary house in an area where the wind blows, and the utility value is particularly large as a cover for a disposal site by burying waste.
