2. Description of the Related Art As a roof frame of a variable shape which has been proposed, for example, there is one having the following configuration (for example, see US Pat. No. 5,024,031). The stretch member is manufactured such that the pivot point at the approximate center of the long stretch member and the pivot points at both ends thereof are not on the same line. A pair of struts having slightly different lengths and pivot point locations are rotatably connected at their central pivot point to produce a scissors-type member.
A first scissor-shaped member is manufactured from a pair of struts, a number of first scissor-shaped members are arranged in a ring with connecting pieces therebetween, and each of the first scissor-shaped members is provided in a ring shape. The ends are pivotally connected to each connecting piece at their pivot points to form a first annular assembly. A second scissor-type member is fabricated with a pair of struts slightly shorter than the pair of struts of the first scissor-type member, and a second scissor-type member is provided inside each first scissor-type member of the first annular assembly. And each of the outer ends of each of the elastic members of each of the second scissor-type members is rotatably connected to the inner connecting piece of the first annular assembly, and each of the elastic members of each of the second scissor-type members is rotatable. Connecting pieces are respectively disposed between the inner ends of the members, and the respective inner ends of the struts are pivotally connected to the connecting pieces at their pivot points to form a second annular assembly. . The third scissor-type member is manufactured using a pair of struts slightly shorter than the strut of the second scissor-type member,

In the roof frame of the above-mentioned proposed variable shape type, the projecting member is manufactured so that the pivot point at substantially the center and the pivot points at both ends thereof do not come on the same line. Since it is necessary to prepare various types of tension members having different lengths and positions of pivot points, it is expensive to manufacture the scissors-shaped member. In addition, the roof frame proposed above has a plurality of scissor-shaped members, each end of each of which is rotatably connected using a connecting piece. It takes a lot of trouble and cost to connect. Further, since the roof frame proposed above is constructed by connecting the respective strut members of a large number of scissors-shaped members with the connecting pieces, the expansion / contraction operation can be performed smoothly if the accuracy of the strut members, the connecting pieces, etc. is not high. In addition, there is a drawback that it is not possible to construct a product with good operability and shape retention. The problem to be solved by the present invention is to provide a roof frame using a multiple polygonal type link mechanism which does not have the above-mentioned drawbacks of the above-mentioned proposed roof frame, in other words, has a simple structure and operability. Another object of the present invention is to provide a roof frame using a multi-polygonal link mechanism that has good shape retention and is relatively inexpensive to construct.

The double hexagonal link mechanism 2 has an outer regular hexagonal link 2A as shown in FIGS.
And an inner regular hexagonal link 2B. Each side of the outer regular hexagonal link 2A is a pair of outer link members 2Aa having the same length.
Of the pair of outer link members 2Aa constituting each side of the outer regular hexagonal link 2A are connected to the outer vertex. An outer regular hexagonal link 2A is formed by connecting the outer vertex connecting shafts at a position corresponding to each vertex of the regular hexagon of the outer regular hexagonal link. In addition, each side of the inner regular hexagonal link 2B is a pair of inner link members 2 of equal length.
One end of Ba is rotatably connected to each other by an inner midpoint connecting shaft, and the other end of the pair of inner link members 2Ba forming each side of the inner regular hexagonal link 2B is connected to the outer end. The inner regular hexagonal link 2 is rotatably connected by a point connecting shaft, and the vertex of the regular hexagon of the inner regular hexagonal link is positioned at a position corresponding to the midpoint of each side of the regular hexagon of the outer hexagonal link.
Construct B.

As shown in FIGS. 3A to 3C, the double octagonal ring mechanism 3 has an outer regular octagonal link 3A.
And an inner regular octagonal link 3B. Each side of the outer regular octagonal link 3A is formed by rotatably connecting one end of an outer link member 3Aa of equal length to each other with an outer midpoint connecting shaft, thereby constituting each side of the outer regular octagonal link 3A. The other end of the pair of outer link members 3Aa is rotatably connected by an outer vertex connecting shaft, and each outer vertex connecting shaft is positioned at a position corresponding to each vertex of the regular octagon of the outer regular octagonal link 3A. The outer regular octagonal link 3A is configured. Further, each side of the inner regular octagonal link 3B is connected to the inner link member 3Ba having the same length.
Of the pair of inner link members 3Ba forming each side of the inner regular octagonal link 3B is connected to the outer middle point. The inner regular octagonal link of the inner regular octagonal link 3B is connected to the inner regular octagonal link 3B at a position corresponding to the midpoint of each side of the regular octagonal side of the outer regular octagonal link 3A. Configure.

Each side of the outer polygonal links 1A to 3A and the inner polygonal links 1B to 3B bends inward at an outer midpoint connecting axis and an inner midpoint connecting axis at the midpoint.
Therefore, the double polygonal link mechanism shifts the outer vertex connection axes corresponding to the vertices of the outer polygonal links 1A to 3A toward the centers of the outer polygonal links 1A to 3A. 1A to 3A and the outer and inner link members 1Aa to 3Aa of the inner polygonal links 1B to 3B,

In the multi-polygon type link mechanism, when the number of corners of the polygon is changed, the following values (1) and (2) change. (1) Frame aperture ratio, that is, the ratio of the area of the outer polygon to the area of the inner polygon inscribed therein. (2) Reduction ratio of the outer polygon, that is, the ratio of the length of the outer polygon when it is fully opened to the difference between when it is fully closed and when it is fully closed, from the vertex to the center of the outer polygon. In the case of the double rectangular link mechanism shown in FIGS. 1A to 1C, the frame opening ratio is 50%, the reduction ratio is 0.05, and the frame opening ratio is 0.05%. In the case of a double hexagonal link mechanism, the frame opening ratio is 76% and the reduction ratio is 0.1%.
In the case of the double octagonal link mechanism shown in FIGS. 3A to 3C, the frame opening ratio is 84% and the reduction ratio is 0.3. As the number of corners of the polygon increases, the frame aperture ratio and the reduction ratio increase. As can be easily guessed from FIGS. 1 to 3, if the triple polygonal link mechanism is further added to the inside of the double polygonal link mechanism, the reduction rate of the outer polygon is significantly reduced, and The amount of movement of the vertex of the outer regular polygonal link (outer vertex connection axis) leading to full closure is reduced. This reduction in the amount of movement of the vertex means a reduction in the drive stroke of the drive device, and is extremely important from a practical point of view. For the purpose of applying the multi-polygon type link mechanism having the above features to the roof frame of a large building, when the weight and the number of angles of the link are selected,
