行われる。(Operation) In the expanded structure of the present invention, the surface of the skeleton of the aggregate is covered with the panel during the expansion. By sliding the slide member along the connecting rod by the driving means, the opposing first and second trusses are in the same direction along the intermediate longitudinal truss aggregate in the process of convoluting the deployed structure. They are folded in two and approach each other. Along with this, the connecting aggregates connected to one end side and the other end side of both trusses are bent in an inverted V shape while being connected to each other by the connecting aggregates, and are folded in two in the same direction as the trusses. In the end, the structure is folded compactly into a plate shape with the panel still incorporated. In the case of unfolding, if the action of the drive means is released, the action opposite to the above is performed by the action of the elastic means.

って行うことができる。スライド部材へどのようにして
駆動力を加えるかについては、一例を後で詳述する。To fold the unfolded structure of FIG. 1, as shown in FIG. 2, the intermediate node members 19a, 19b, 19c are in the plane parallel to the planes of the first and second trusses T 1 , T 2 on both sides. Is displaced upward in the figure. As a result, the connecting aggregates 13, 14, 15 on both sides rotate so as to form an inverted V shape in the respective virtual planes including the vertical truss aggregates 1a and 7a, 1b and 7b, 1c and 7c, The panels P on both sides have a roof shape. On the other hand, the slide member 26a,
26b and 26c are relatively displaced downward in the figure along the connecting rods 25a, 25b and 25c. Further, the intermediate node members 20a, 20b, 20c and the connecting aggregates 16, 17, 18 on the lower side in the figure also perform the same displacements as the upper intermediate node members and the connecting aggregates on the figure. The above displacement is actually caused by, for example, the slide member 26.
This can be done by first applying a driving force for displacement to a, 26b, 26c. An example of how to apply the driving force to the slide member will be described later in detail.
以上のような変位が進行するにつれ、両側のパネルＰ
の傾斜は益々急になり、第１、第２のトラスT1,T2は漸
次接近する。As the above displacement progresses, the panels P on both sides are
Is steeper, and the first and second trusses T 1 and T 2 gradually approach each other.
上述の変位と同時に、両トラスT1,T2は次に述べるよ

（上端）に節点部材3b,9bを介して連結されている連結
骨材14,14も図において右方へ変位させられる。Simultaneously with the above-mentioned displacement, both trusses T 1 and T 2 undergo the following deformation. That is, as shown in FIG. 3, the vertical truss aggregates 1b, 7b in the middle of the trusses T 1 , T 2 are located on the right side of the vertical truss aggregates 1a, 1c, 7a, 7c on both sides thereof. Is displaced to. As a result, the two trusses T 1 and T 2 are bent in a V shape when viewed in the direction of the truss surface (when viewed from above in FIG. 3) such that the intermediate vertical truss aggregates 1b and 7b serve as bending tips. Along with this, the connecting aggregates 14, 14 connected to one end (upper end) of the intermediate vertical truss aggregates 1b, 7b via the node members 3b, 9b are also displaced to the right in the figure.

時に進行するものである。Such bending displacement is caused by the first and second bending in the state of FIG.
When the trusses T 1 and T 2 are closer to each other and the whole structure is close to a flat plate, two flat plate-like structures are provided along the intermediate vertical truss aggregates 1b and 7b and the connecting aggregates 14 and 14. It becomes easier to understand by thinking that it is folded into. However, in reality, the approaching displacement and the folding displacement of the first and second trusses T 1 and T 2 simultaneously proceed.

1cにも設けることができる。To automatically perform the deformation in the developed state from a folded state as described above, as shown in FIG. 5, the truss T 1,
As shown by arrows A and B, a torsion spring 33 that gives a rotational force can be installed. These torsion springs 33 are mounted around the pivots of the nodal members 3a, 3b, 3c, 5a, 5b, 5c and the transverse truss aggregates 4, 4, 6, 6 and the first truss T 1 A force that constantly tries to expand from the folded state of FIG. 5 to the plane state of FIG. 1 is applied. The torsion spring 33 is similarly provided on the second truss T 2 . In addition, this kind of spring is used for the node members 19a, 19b, 19c, 20a, 20b, 20c, 9a, 9b, 9c, 11a, 11b, 1 in FIG.
It can also be provided in 1c.

The aggregate structure supporting the panel P 1 is the same as that shown in FIG. However, when the panel P 1 having a curvature is used, when the panel P 1 is folded in the same manner as in the case of FIG. 3, the convex surfaces of the panel P 1 face each other,
As in the case of the flat panel P, it is difficult to obtain an approaching state close to surface contact, and the storage efficiency at the time of folding is deteriorated. In order to solve this problem, as can be seen from FIG. 15, of the two adjacent sections over the first and second trusses T 1 and T 2 without installing a panel for each of the above sections of the aggregate structure. Panels P 1 are attached to one of them alternately. As a result, the adjacent panels P 1 have a convex surface and a concave surface facing each other at the time of folding as shown in FIG. 16, and the storage efficiency is improved. In this embodiment, the aggregate structure is
As shown in the figure, it is given a shape corresponding to a curved surface formed by a composite of many panels P 1 .

It is possible to fold the deployable structure with panels attached to the compartments in a small size and to fold it into a thin shape, or to create a deployable shape. In the present invention, not only the quadrilateral compartments to which the panels are attached but also the quadrilateral compartments that form other skeletons do not lose their shape when folded, and any bone agent that composes any quadrilateral compartment is bent in the middle of folding. Since it is not, it is structurally strong and simple, and the structure is lightweight. Further, the structure is advantageous in that it is flattened when folded and then bent into a V-shape to be further miniaturized.
