Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flexible structure, and more particularly to a flexible structure in which the shape of the flexible structure can be easily changed or moved by moving a fluid. It is about structure.

[0002]

2. Description of the Related Art In recent years, a flexible structure whose external shape is formed by filling the inside with a fluid has been
It has been formed into external shapes such as "people", "animals", and "imaginary animals", and it has come to be used by being attached to the walls of department stores and buildings, or by standing on its own in open spaces.

Further, the flexible structure has "eyes move".
It is now required to add "movement" such as "waving hands" and "moving legs".

Further, there is also a method of floating a flexible structure in a concert hall, a baseball field, etc. where a large number of people gather and adding various "movements" by remote control using wireless to improve the advertising effect. It came to be used.

As described above, it is considered that flexible structures will be required for various purposes in the future.

[0006] Traditionally, "filling" of a flexible structure, whose exterior shape is formed by filling the interior with a fluid.
As a method of providing the above, Japanese Utility Model Publication No. 54-124490, Japanese Utility Model Publication No. 56-117788, Japanese Patent Publication No. 2-1.
It is disclosed by Japanese Patent No. 1918. Both publications use a means of "bending" by pulling a string.

A method of "bending" a flexible structure disclosed in Japanese Patent Publication No. 211918/1990 will be described below.

Referring to FIG. 25, a conventional flexible structure 9
Reference numeral 0 is composed of a main body 90a having a cylindrical shape and a pedestal 90b. On the pedestal 90b of the flexible structure 90,
Air holes 92 are provided. Air is always sent into the inside of the main body 90a through the air holes 92. This causes the flexible structure 90 to stand upright and assume its external shape.

Next, a method of bending the flexible structure 90 having the above-described structure will be described with reference to FIGS. 25 to 27.

FIG. 25 shows an overall side view of the flexible structure 90. FIG. 26 shows a side sectional view of the flexible structure 90. 27 is an end view taken along the line XX in FIG.

In each figure, an arrow Q indicates the bending direction of the flexible structure 90. An opening 98 is formed in the bending portion A of the flexible structure 90 on the side opposite to the bending direction. Both ends 93, 94 of the opening 98 form a bending fulcrum.

A margin cloth 95 is sewn to the inside of the main body of the opening 98 so as to close the opening.

Next, the flexible structure 90 has an opening 98.
The fitting 96 is fixed to the tip end side of the fitting 96. Further, the operation string 97 is fixed to the attachment 96.

Next, referring to FIG. 28, the flexible structure 9
0 bends in the arrow Q direction with the fulcrums 93 and 94 as a pair of fulcrums by pulling the operation string 97 in the R direction shown in the figure. At this time, the body cloth near the attachment 96 is indicated by the arrow R
Draws in the direction to form wrinkles and reduces the internal volume near the fixture 96. Therefore, the flexible structure 90
Bending increases its internal pressure. On the other hand, the allowance cloth 95 uses the fulcrums 93 and 94 as a pair of fulcrums, and expands into a tension state in response to an increase in the internal pressure of the flexible structure 90. As a result, the increase in the internal pressure of the flexible structure 90 is offset, and the change in the internal pressure of the flexible structure 90 before and after bending can be minimized.

With the above structure, the bending of the flexible structure is
This can be easily done by applying a relatively small force to the operation string 97.

[0016]

However, the bending means of the flexible structure has the following problems.

An operation string for applying a bending force is provided inside the flexible structure body, and an allowance cloth for offsetting the increased pressure is provided on the opposite side. As a result, the bending direction of the flexible structure 90 is limited to one direction.

The bending portion of the flexible structure 90 is usually in a tensioned state, but when a force is applied to the operation string to draw it, it becomes wrinkled and becomes unsightly in appearance.

The force applied to the operating cord is concentrated on one point of the fixture, and there is a high risk that the cloth at the fixture attachment portion of the flexible structure will be heavily fatigued and damaged.

Due to the elongation of the operation cord and the elongation of the cloth at the mounting portion of the fixture, there is a limit in giving the flexible structure a smooth motion and a delicate motion.

The present invention has been made to solve the above-mentioned problems, and enables a flexible structure to be given a smooth motion and a delicate motion, and the flexibility can be obtained without using an operation cord. An object of the present invention is to provide a flexible structure capable of changing or moving the form of the structure.

[0022]

In order to solve the above problems, a flexible structure based on the invention according to claim 1 is
A main fluid chamber forming the shape of the main body, a first auxiliary fluid chamber connected to the main body and airtightly isolated from the main fluid chamber, and a first auxiliary fluid chamber connected to the main body and airtightly isolated from the main fluid chamber And a second auxiliary fluid chamber connected to the first auxiliary fluid chamber via an openable / closable flow path, and a fluid moving means for exchanging fluid between the first and second auxiliary fluid chambers. There is.

According to a second aspect of the present invention, there is provided a flexible structure, which includes an outer skin member forming an outer surface of the flexible structure body, and the outer skin member, which is connected to the outer skin member and cooperates with a part of the outer skin member to be closed. A first auxiliary skin member that forms a first auxiliary fluid chamber, and a first auxiliary skin member that is connected to the outer skin member at a distance from the first auxiliary fluid chamber and is closed in cooperation with a part of the outer skin member. A second auxiliary skin member forming a second auxiliary fluid chamber, a flow path connecting the first auxiliary fluid chamber and the second auxiliary fluid chamber, and the first and second flow paths provided in the flow path. Between the auxiliary fluid chambers of
And a fluid moving means for exchanging the fluid.

[0024]

According to the flexible structure of the first aspect of the present invention, the shape of the flexible structure can be easily changed by exchanging fluid between the first and second auxiliary fluid chambers. Move it. For example, in a flexible structure floating in the air, when the fluid having a large specific gravity is exchanged between the first and second auxiliary fluid chambers, the center of gravity of the structure moves. With this movement of the center of gravity, the flexible structure performs a tilting motion or a rotating motion.

Next, in the flexible structure according to the second aspect of the present invention, the auxiliary fluid chamber is directly connected to the outer skin member. The outer skin member in contact with the one auxiliary fluid chamber from which the fluid is drawn loosens, and the outer skin member in contact with the other auxiliary fluid chamber filled with the fluid expands. As a result, the flexible structure bends toward the one auxiliary fluid chamber side.

The first auxiliary skin member forming the chamber and the first auxiliary fluid chamber are separated from each other, and are connected to the outer skin member to form a second auxiliary fluid chamber closed in cooperation with a part of the outer skin member. Second
Of the auxiliary skin member, a flow path connecting the first auxiliary fluid chamber and the second auxiliary fluid chamber, and the first and second
And a fluid moving means for exchanging fluid between the auxiliary fluid chambers. This makes it possible to give a smooth movement to the flexible structure and a delicate movement by utilizing the change in pressure and the movement of the center of gravity due to the movement of the fluid between the auxiliary fluid chambers, and does not use the operation cord. Thus, it is possible to change or move the shape of the flexible structure.
