Reference numeral 1 is a membrane structure, and the membrane structure 1 is composed of a skeleton 3 and a membrane body 5 stretched on the skeleton 3. The skeleton 3 comprises two supporting units 7 formed in a convex shape upward, one upper connecting unit 9 and two side connecting units 11, and each unit 7, 9 and 11 is made of an air tube. is there.

The support unit 7 is composed of a pair of leg portions 13, and the pair of leg portions 13 extend in a substantially X shape when viewed from above the membrane structure 1 as shown in FIG. As shown, the membrane structure 1 extends upward in a substantially inverted V shape when viewed from the front. In addition, as shown in FIG. 4, when viewed from the side of the membrane structure 1, the lower part and the upper part are closer to each other and are connected at the upper part. It is formed in a circular shape. Explaining the leg portions 13 in more detail, each leg portion 13 is configured by connecting two tube bodies 1301 at an upper portion 1303, and a weight 15 for preventing lifting is provided inside the lower end of each tube body 1301. It is housed.

The supporting unit 7 having the above-mentioned structure
Are arranged so that the upper portions 1303 face each other. The upper connection unit 9 is connected between the upper portions 1303 of the support units 7, and the upper portions 1303 of the support units 7 are connected.
The side connection units 11 are connected to the outer sides of the respective.

The upper connection unit 9 is composed of a single tube body 901 that extends linearly in the horizontal direction. Both ends of the tube body 901 are irremovably integrated with the center of the upper portion 1303 of each support unit 7. still,
Connect both ends of the tube body 901 to the upper part 13 of each support unit 7.
It is needless to say that it may be detachably connected to the center. Further, one or both ends of the tube body 901 are internally communicated with the corresponding support unit 7 and are configured to expand simultaneously when the support unit 7 expands.

The side connection unit 11 is composed of a tube body 1101 extending vertically in an arc shape.
The upper end is detachably connected to the center of the upper portion 1303 of the support unit 7 via the detachable portion 16. A weight 15 is housed in the lower end of the tube body 1101 as in the support unit 7.

A film body 5 is stretched over approximately the upper half of the skeleton 3 having the above structure, and the film structure 1 is constituted by the skeleton 3 and the film body 5. The number of blowers for expanding the air tube depends on the scale of the skeleton 3. For example, when one blower is sufficient for the skeleton 3, as shown in FIG. 4, the legs 13 of the support unit 7 are provided.
The blower 17 is disposed above the weight 15 at the inner lower end of one tube body 1301 of the four tube bodies 1301 that make up the support unit 7, the upper connection unit 9, and the side connection. When the number of blowers 17 is smaller than the number of units 11, each unit 7, 9,
It suffices to provide a communication port for communicating the inside with each other at the connection portion of 11.

Since this embodiment is constructed as described above, for example, when it is desired to make the membrane structure 1 large, the support unit 7 and the upper connection unit 9 are added as shown in FIG. That is, the side connection unit 11 is removed, the support units 7 are arranged outside the support unit 7 with the upper portions 1303 facing each other, and the removed side connection units are provided on the side surfaces of the upper portion 1303 located outside these support units 7. The unit 11 is connected, and the upper connection unit 9 is connected between the side surface of the upper part 1303 located inside the added support unit 7 and the side surface of the upper part 1303 located outside the existing support unit 7. The number of support units 7 and upper connection units 9 added in this way is arbitrary, and therefore the size of the membrane structure 1 can be changed according to the number of users and the shape of the site. In addition, since the weight 15 and the blower 17 are housed in the lower end of the inside of the tube body 1301, the weight 15 and the blower 17 cannot be seen from the outside, and the appearance of the membrane structure 1 can be enhanced, and the membrane structure 1 The practical value of 1 can be further enhanced.
