Utility Model Registration No. 31307779 JP 2003-184349 A

The air house described in Patent Document 1 has no partition in the wall portion forming the dome, and the interval between the sheet constituting the outer surface and the sheet constituting the inner surface at the top of the air house is large, and as it approaches the floor portion. Since the interval is small, it lacks stability. For this reason, it is likely to be greatly deformed when a force is applied by wind blowing or the like.
The air tent described in Patent Document 2 is configured on the assumption that a plurality of units are connected and used. Therefore, the spherical body unit is not semi-circular but is semi-circular when viewed from above. When setting up a spherical dome-shaped tent, since two hemispherical units are required, two or more blowers are required, and the setting and withdrawal are complicated. Furthermore, since the thickness of the wall of the unit is the same at the top and bottom of the spherical body unit, it is easily deformed when a force is applied by blowing wind or the like.
The present invention solves the above problems, and an object thereof is to obtain an air tent that hardly deforms even in a strong wind and is easy to be folded after the air is removed.

The present invention has the following configuration.
1. The outer surface and the inner surface are dome-shaped, and are air tents with an entrance at the bottom.
The wall portion has an outer membrane that forms an outer surface and an inner membrane that forms an inner surface, and is further connected to the outer membrane and the inner membrane, and vertically partitions a space between the outer membrane and the inner membrane. A plurality of film-like spacers having properties are provided in the vertical direction from the bottom to the top,
An air tent in which the distance between the outer membrane and the intima at the bottom is larger than the distance between the outer membrane and the intima at the top.
2. 2. The air tent according to 1, wherein the top has a hole formed by a tubular material penetrating between the outer membrane and the inner membrane.
3. The air tent according to 1 or 2, comprising a floor portion made of a sheet-like material and integrated with a lower surface of the bottom portion.
4). The air tent according to any one of 1 to 3, having a container storing water and / or sand and / or a storage part storing a bag at the bottom.
5). The air tent according to any one of 1 to 4, wherein the shape viewed from above is a quadrangle, a hexagon, an octagon, a circle, or an ellipse.

According to the present invention, the whole can be inflated by injecting air from only one place of the air tent. Since the distance between the outer membrane and the intima at the top is larger than the distance between the outer membrane and the intima at the top, the air tent moves without being greatly deformed even when an external force is applied from the lateral direction such as under strong wind. There is nothing. Further, when the air is evacuated and folded, the wall portion is squeezed in a state where the film spacer provided between the inner membrane and the outer membrane is fixed to the outer membrane and the inner membrane. Therefore, after squeezing, the outer membrane, the inner membrane, and the membrane spacer are integrated into one sheet, and the wall itself has no corners. It is very easy to fold an air tent.
Further, since water and / or sand can be stored in the lowermost portion of the wall portion, the water or sand can be used as a heavy stone and can be fixed facing the wind or the like.

(Whole structure of air tent)
The air tent of the present invention has a quadrangular, hexagonal, octagonal, circular or elliptical floor shape, and is formed so that a wall portion rises from the floor of this shape. Since it is a dome shape, the wall rising from the floor gently curves to the top of the air tent, so the ceiling and wall are not clearly separated.

Embodiments will be described with reference to the drawings.
1 is a side view of an air tent of the present invention having a circular shape when viewed from above, FIG. 2 is a top view, and FIG. 3 is a cross-sectional view taken along the line AA in FIG. The room size of the air tent of the present invention may be any size that allows a person to enter. For example, it is sufficient if it is wide enough for about 3 to 15 people to enter, but it is not limited to this size.
As shown in FIG. 1, in the air tent of the present invention, the wall 1 rising from the floor gently curves to the top of the air tent, and the wall 1 rising from the floor extends to the top as it is. The dome shape is unclear.
An entrance / exit 2 is formed in the wall 1. The air tent of the present invention is preferably provided with about 1 to 4 doorways. However, it shall be provided in consideration of the size and application of the air tent. Doors can be arbitrarily attached to the doorway.
The outer surface of the tent is formed by sewing a plurality of sheets and cloth. There is a seam 3 on the outer membrane formed by such means as sewing. The plurality of seams 3 formed in the air tent of the present invention extend substantially perpendicular to the floor surface from the bottom to the top of the air tent.
The seam 3 is a place where a film spacer is fixed to the outer membrane and the inner membrane by sewing or the like. As shown in FIG. 1, a plurality of such seams 3 are formed in the air tent.

Furthermore, you may provide the one or more storage parts 4 in the lower part of the wall part 1 of an air tent. Each storage unit 4 can store a container and / or bag storing water and / or sand as a weight, and further store a device or an article in place of the weight. When the storage unit 4 is provided, the storage unit lid can be opened and closed after the air is blown into the air tent, and the inner surface of the storage unit 4 communicates with the space filled with air by the inner surface of the wall. Good or not. In any case, the storage unit 4 may have a lid, but when communicating, it has sufficient airtightness when the lid is closed.
By storing these heavy stones, etc., the air tent will fly or move inadvertently even when air is supplied into the air tent or when crosswinds are blown when using the air tent. Can be prevented.

A daylighting window L can be provided at an arbitrary position on the wall of the air tent. The window L is provided by forming the corresponding locations of the outer membrane and the inner membrane with transparent members.
The air tent of the present invention has at least one air hole (not shown) that can be sealed and covered. And the air blower B, such as a blower, is connected to the air hole via the pipe | tube P, and it blows in the whole air tent. Air is supplied from the blower B between the outer membrane and the inner membrane of the air tent to inflate the air tent. When the space between the outer membrane and the inner membrane of the air tent of the present invention is formed with a certain degree of airtightness, the air blowing may be stopped after sufficiently filling with air. If a large amount of filled air escapes when the air blowing is stopped, the air blower is operated at an arbitrary frequency or continuously during the use period of the air tent.
In FIG. 1, the blower B is installed outside the air tent. However, the blower may be installed in a space filled with air between the outer membrane and the inner membrane, and air may be introduced from the outside.

  FIG. 2 is a top view of the air tent, and an air hole 5 can be provided near the top of the air tent at the center thereof. The air hole 5 has a function of discharging and collecting the air trapped inside the air tent. The air hole 5 is made of a tube-shaped member made of a material having no air permeability. The air tent shown in FIG. 2 has a circular shape, but is not limited thereto, and may be a quadrangular shape, a hexagonal shape, an octagonal shape, a circular shape, an elliptical shape, or an indefinite shape. A plurality of air holes 5 can also be provided.

FIG. 3 is a cross-sectional view taken along the line AA in FIG.
As shown in FIG. 3, between the outer membrane 6 and the inner membrane 7, a membrane spacer 8 connected to each other by sewing with a thread or the like is provided. The membrane spacer 8 is connected to the outer membrane 6 and the inner membrane 7 over the entire height from the bottom to the top of the air tent.
Therefore, the air inside can be leaked from the seam. At this time, there is a possibility that the air tent is deflated due to leakage of the internal air from the moment when the blowing is stopped.
Both the outer membrane 6 and the inner membrane 7 are made of a sheet-like material of a known flexible material that does not have air permeability. Each membrane spacer 8 is made of a breathable material such as a net-like material, and in the air tent, each membrane spacer 8 is positioned substantially along the vertical direction, and the membrane spacer 8, the bottom surface, the outer membrane 6 and the inner membrane The portion surrounded by the film 7 forms a unit such as a long and narrow substantially continuous fan. The film spacer 8 is connected to a member that forms the air hole 5 at the top of the air tent. However, if there is no air hole 5, a plurality of film spacers 8 may be fixed at one point. At the bottom of the air tent, the film spacers 8 can be provided at intervals of 40 cm to 80 cm in the lateral direction, but are not limited to this interval.

As described above, the air tent is formed by employing the air-permeable membrane spacer 8 so that the entire air tent is evenly inflated or deflated at the time of the air blowing and after the air blowing is stopped. be able to.
In addition, the shape of the air tent can be maintained even after the air blowing is stopped by covering all the seams with an adhesive tape having no air permeability. At this time, it is necessary to suck the internal air when the air tent is folded.

4 is a cross-sectional view taken along line BB in FIG.
In FIG. 4, it can be seen that the maximum value d2 of the distance between the outer membrane and the intima at the bottom is larger than the minimum value d1 between the outer membrane and the intima at the top. The distance between the outer membrane and the inner membrane increases continuously or discontinuously from the top to the bottom. As a result, the bottom wall of the air tent becomes thicker, so that the shape of the entire air tent can be maintained appropriately. Further, even when a wind is blown and a force is applied in the lateral direction from the outside, the deformation of the entire air tent can be further reduced.
Therefore, the value of d1 is preferably 5 cm or more, more preferably 10 cm or more, still more preferably 15 cm or more, and most preferably 20 cm or more, preferably 50 cm or less, more preferably 40 cm or less. The value of d2 is preferably 100 cm or less, more preferably 80 cm or less, still more preferably 60 cm or less, and preferably 40 cm or more.
Note that if the outer membrane 6 and the inner membrane 7 are rigid, they move and fly in the wind as in the case of a tent in which only the roof portion is formed by a metal support.
Further, since the appearance of the air tent is based on a hemispherical shape, even if a pressure is applied to the wall portion 1 due to a cross wind, the wind passes along the surface of the hemispherical outer membrane 6, so You can make the wind flow toward you. As a result, the pressure from the side to the air tent is reduced, and the air tent is not deformed by receiving a cross wind more than necessary.

For example, one or more speakers S can be provided in the air tent. The height at which the speaker is installed may be adjusted to the position of the ear depending on the posture of the person in the room, such as when standing, hanging on a chair, or sleeping. In particular, the interior shape formed by the inner membrane 7 is approximately hemispherical, and more appropriate acoustic effects can be obtained by selecting the material of the inner membrane 7. Further, a moving image may be projected onto the intima 7, a screen or display for displaying a moving image may be installed indoors, or may be fixed to the intima 7. Other necessary equipment and furniture can be installed.
Moreover, you may provide the floor part 9 connected with the air tent main body in the room | chamber interior of an air tent. As such a floor portion, any material such as a sheet made of the same material as the outer membrane or the inner membrane and a sheet made of a material different from the outer membrane or the inner membrane can be selected. The floor may be a single sheet, or may be a bag having an upper layer and a lower layer and filled with air between them. Further, as means for connecting to these sheets and the like, any means such as sewing with the air tent body, adhesion, temporary fixing with a button or the like can be adopted.
Moreover, you may provide the floor part which is not connected with an air tent instead of the floor part which is connected with an air tent main body and is integral. In this case, means known as a flooring material such as a cocoon worm, an air mat, etc., such as a sheet made of the same material as the outer membrane or inner membrane, a sheet made of a material different from the outer membrane or inner membrane, and the like can be used.
The air hole 5 may be formed by stitching the outer membrane 6 and the inner membrane 7 together at the top of the air tent. Further, the tubular object 10 may be used as an air hole by inserting and fixing the tubular object 10 in the air hole 5 formed thereby. Furthermore, the outer membrane 6 and the inner membrane 7 can be sewn to the outer periphery of the tubular article 10 so as to be integrated with the tubular article.

The process for installing the air tent of the present invention is shown below.
FIG. 5 shows an air tent before the air is blown into the interior, and basically, air is not actively introduced into the interior like a floating ring before the air is introduced. However, it is shown in a slightly swollen state for the purpose of illustration.
A blower (not shown) is connected to an air hole (not shown) with an air hole (not shown) by an air hose or the like to the air tent having the outer membrane 6, the inner membrane 7, the membrane spacer 8, etc.

FIG. 6 shows a state in which a little air is introduced.
As can be seen from FIG. 6, the portion forming the wall portion is substantially raised. Then, the entire air tent is blown uniformly through the film spacer 8.

By continuously blowing air, it is possible to obtain an upright air tent as shown in FIG.
And after using an air tent, the inside air can be extracted and folded. By turning off the power supply of the blower and stopping the blow, normally, air leaks from the seam of the entire air tent, particularly from the seam, so that the entire air tent is evenly deflated. In addition, when storing a heavy stone etc. in the storage part 4, taking out a heavy stone etc. before turning off the power supply of a ventilation apparatus is desirable from the point of workability | operativity when folding.

The progress due to the escape of air is the reverse of the progress of FIG. 5, FIG. 6 and FIG. After the air has sufficiently escaped, the state shown in FIG. 5 is obtained. Thereafter, the air tent that has become a substantially circular shape is folded by an arbitrary folding method, so that it can be made very compact.
For example, as can be seen from FIGS. 5 and 6, the deformation of the air tent when the air escapes maintains the overall shape and the positional relationship of the membrane spacer 8 and maintains the curved surface of the outer membrane and the inner membrane. Get up. Therefore, the wall portion is bent so as to be placed inside by the curved surface of the outer membrane and the inner membrane, so that the shape of the air tent after the air has been removed is always as shown in FIG. Thereafter, the operator can easily fold the entire air tent together while venting the air inside.

A plurality of the air tents of the present invention can be used in combination. For example, by connecting and integrating the entrances and exits of the air tent shown in FIG. 1, each air tent can be made as if it were a continuous room. In addition, it is possible to allow people to enter and exit from other opening / closing openings.
When a plurality of air tents are connected in this way, for example, air holes for connecting the air tent blower can be connected by a connecting pipe. As a result, for example, in a state where two or three air tents are connected, one air blower B can be connected to the air hole of any one air tent, and all the air tents can be raised at the same time.

  When connecting the entrances and exits of a plurality of air tents as described above, a space between the entrances and exits of the two opposing air tents may be covered with a sheet-like material. At this time, the sheet-like material may or may not be fixed around the entrance / exit of the two air tents.
