DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. The tent shown in FIGS. 1 to 5 is a relatively small air tube tent used as, for example, a work room or a storage room for storing tools, components, and the like at a construction site or the like. In this air tube tent, a frame structure a composed of a combination of cylindrical air chambers is installed on a floor sheet c laid on the ground (FIG. 5), and a roof surface and a periphery of the frame structure a are provided. It is configured by covering the four sides (front, back, left and right sides) with awnings b.

The frame structure a of the air tube tent is as follows:
It is constituted by connecting a pair of columnar air chambers a1 formed in a substantially arch shape with a connecting air chamber a2 and a connecting air chamber a3. Although not shown, the case where the connection air chamber a3 is not connected and the provision of several beam air chambers are optional. The columnar air chamber a1 is formed in a substantially arch shape by using a rubberized cloth or the like, and lower portions at both ends of the air chamber a1 are configured as leg portions a10 of the frame structure a. When the connection air chamber a3 is not connected, the lower part on both sides of the columnar air chamber a1 becomes the leg part a10.

The two columnar air chambers a1 are opposed to each other at a distance corresponding to the depth of the tent.
One or several beam air chambers a2 are erected between the central portions of one. Then, the legs a10 at both ends of the columnar air chamber a1
By arranging the connecting air chambers a3 between each other, the two columnar air chambers a1 are integrally connected by the beam air chambers a2 and a3, thereby forming a self-supporting frame structure a. The frame structure a is configured as a single air chamber by connecting both columnar air chambers a1 to each other via a beam air chamber a2 and a connecting air chamber a3.

As described above, by connecting the two columnar air chambers a1 by the beam air chamber a2 and the connecting air chamber a3, the distance between the leg portions a10 is maintained at a constant distance, and the columnar air chambers a1 are maintained. The bending deformation of the leg a10 can be effectively prevented. On both left and right sides of the beam air chamber a2 connecting the two columnar air chambers a1, tension lines a5 made of a rope, a belt, or the like are provided so as to prevent the gap between the right and left ceiling portions of the two columnar air chambers a1 from expanding. I support it. Both ends of the tension line a5 are detachably connected via a hook 12 to a fixture 11 fixed to the column-shaped air chamber a1 side. It is also possible to provide an air chamber similar to the beam air chamber a2 in place of the above-mentioned line a5.

In addition to the connecting air chamber a3, short-axis fixed air chambers a4 protrude horizontally and in a cantilever manner beneath the four legs a10 which support the frame structure a so as to be capable of standing. The fixed air chamber a4 is connected or not connected to the air chamber a1. That is,
The two connecting air chambers a3 and the fixed air chambers a4 connected to the legs a10 of the skeleton structure a are formed at the lower part of the columnar air chamber a1 by extending horizontally from the lower ends of the legs a10. And both air chambers a3 and a4 together with the same leg a10,
It functions as a leg a20 that touches the ground.

The frame structure a comprises a leg a10 of both columnar air chambers a1 and a connecting air chamber a connecting the legs a10.
3, and a cantilevered fixed air chamber a4, that is, legs a20 form a substantially U-shaped grounding portion on both left and right sides of the grounding surface, so that the frame structure a is stably self-standing. It is configured to do so. The leg part a20 is constituted by both or one of the connection air chamber a3 and the fixed air chamber a4. When the two air chambers a3 and a4 are not connected, the leg part a2 is formed.
0 is not formed. In addition, the above-mentioned frame structure a
The air inlets 13 are provided one by one on the side surface of the base 10. Further, a safety valve 1 for avoiding excessive pressure in each of the air chambers a1 to a4.

As a result, the legs a10 and a20 are fixed to the installation position on the floor sheet c by the holding force of the rising portion 21, and are further held so as not to be displaced from this position.

The rising portion 21 provided on the outer peripheral portion of the floor sheet c has a good holding function by being set to a height substantially equal to the diameter of the connecting air chamber a3 as in this embodiment. However, the height of the rising portion 21 is not limited to this, and may be set slightly higher or lower than this. Further, the rising portion 21 of the floor sheet c is configured such that the front and rear center portions are cut off so that the right and left rising portions 21 are separated from each other. As long as the floor sheet can be held, it may be provided over the entire circumference of the floor sheet, or the comb may be provided with a part thereof cut off. Furthermore, the frame structure of the air tube tent is not limited to the above-described form, and the form of the ceiling, the number of beam air chambers or connection air chambers, and the number of fixed air chambers may be arbitrarily changed.

On the other hand, the roof surface of the frame structure a and the periphery 4

A connection air chamber a3 of a frame structure a 'is placed between the hook-and-loop fastener 35b and the rising portion 21 on the side surface, and a lower edge portion of a blind sheet 34 provided along a lower portion of the awning b from above. By fastening the hook-and-loop fastener 35a, the upper surfaces of the connection air chamber a3 and the fixed air chamber a4, which are the legs a20 of the frame structure a, are covered.

Next, the air tube tent shown in FIG. 10 will be described. The above air tube tent is
The air tube tent shown in FIGS. 1 to 5 is substantially the same as the air tube tent shown in FIGS. 1 to 5 except that the legs of the frame structure c ″ ′ are composed of only the legs a10 at both ends of the columnar air chamber a1. That is, the frame structure does not include the connecting air chamber a3 and the fixed air chamber a4 as described above.

The floor sheet c "" of the air tube tent is flat along the inside of each corner of the rising portion 21 formed along the left and right edges of the floor sheet c "". A frame-shaped leg fitting in which a holding sheet 22 ′ bent substantially in an L shape is attached, and a leg a 10 of the skeleton structure a ″ is fitted between the holding sheet 22 ′ and the rising portion 21. The joint 20 'is formed.

The above frame structure a ″ is replaced with a floor sheet c ″ ″.
When installed on the upper side, the leg a10 is
0 ', the lower end of the leg a10 serving as the ground contact portion fits exactly into the frame of the leg fitting portion 20', and the leg a
10 is substantially completely prevented from shifting in the front-rear and left-right directions. That is, according to the frame structure a ″ of the air tube tent, the leg portions a10 are fixed at the four corners on the floor sheet c at the installation position by the holding force of the fitting portion 20 ′. It is securely held so as not to deviate from this position. As described above, the awning is covered on the skeleton structure a ″ installed on the floor sheet c ″ ″ in the same manner as the air tube tent described above, so that the installation state is the same as that shown in FIG. . In the case of the frame structure a ″ of this embodiment, it is preferable to raise the holding sheet 22 ′ to form the leg fitting portion 20 ′. However, as described above, the holding sheet 22 ′ and the leg fitting Without forming the joint portion 20 ', the leg portion a10 can be held at the corner of the rising portion 21 formed on the outer periphery of the floor sheet c.

As described above, the leg portion of the frame structure of the air tube tent of the present invention may have any shape. The shape of the leg fitting portion into which the leg is fitted may be arbitrarily changed in accordance with the shape of the grounding portion of the leg. Note that the air tube tent of the above embodiment is a relatively small tent configured as a work room used at a construction site or the like, but the air tube tent of the present invention is a comparative example like an evacuation tent at the time of disaster.

[0040]

As described above, according to the present invention, the rising portion is formed along the outer periphery of the floor sheet, and the legs provided in the framework structure are placed on the floor sheet. The leg portions are configured to be held from the surroundings by the rising portions. Therefore, in a state where each leg of the frame structure is placed on the floor sheet, the rising portion abuts on each leg in a form surrounding the periphery, and each leg is moved to a predetermined position on the floor sheet. Can be securely held so as not to deviate from the position. As a result, it is possible to prevent the legs of the frame structure from being displaced from predetermined positions on the upper surface of the floor sheet due to the influence of the weight and wind pressure of the awning, thereby lowering the shape retention force of the air tube tent and loosening the awning. In addition, buckling of the air chamber can be effectively prevented.

As in the air tube tent according to the second aspect, a substantially frame-shaped leg fitting having an open upper surface is provided between the rising portion and the holding sheet raised along the inside of the rising portion. In the case where the lower end of the frame structure is fitted into the leg fitting portion by forming a mating portion, compared to a case where the leg fitting portion is not provided, each of the mating portions has a stronger holding force generated by the above-described fitting relationship. The movement of the lower end of the leg along the upper surface of the floor sheet is more reliably prevented, and each leg can be reliably held at a predetermined position on the floor sheet. Also, the work of placing each leg of the framework structure at a predetermined position on the floor sheet,
It can be easily performed simply by fitting the lower end of the leg into the leg fitting portion provided on the floor sheet. Furthermore, since the lower end of each leg can be inevitably and accurately positioned with respect to the leg installation position on the floor sheet, the framed structure composed of columnar air chambers can be accurately positioned at the fixed position on the floor sheet. Can be assembled.
