本発明に係る正多角形枠の自動方位制御機構の実施例を
図面に基いて説明する。An embodiment of the automatic orientation control mechanism for a regular polygonal frame according to the present invention will be described based on the drawings.
第１実施例として、正多角形枠を正六角形枠として第１
図乃至８図に基いて説明する。As a first example, a regular polygonal frame is used as a regular hexagonal frame.
This will be explained based on FIGS. 8 to 8.

対角線長よりも大である。3 is a funnel-shaped guide port, 4 is an orientation setting part, 5 is a regular polygon guide part 3 has a conical inner surface having a large-diameter upper opening 3a and a small-diameter lower opening 3b, and the diameter of the lower opening 8b is set to accommodate It is larger than the maximum diagonal length of hole 2.

ｃ’、４ｃ’を該切欠き４ｂ。The orientation setting part 4 has a notch 4ti facing oppositely to the inner peripheral surface of a cylindrical part 4m concentrically connected to the lower opening 3b of the funnel-shaped guide port;
The upper end portion 4 of the leaf spring 4c, 4c is provided with <b and bent.
c', 4c' is the notch 4b.

採り得る。The width of the leaf spring 4C is approximately equal to the length of one side S\ of the regular hexagonal frame 10, and both leaf springs 4c, 4c, in a compressed state, are connected to the diagonal line passing through the center of the regular hexagonal frame 10 (7). The maximum gap corresponds to the length, and the gap corresponds to at least the distance between two opposing sides in the repulsed state.

る。The regular polygonal guide part 5 is connected to the orientation setting part 4 with its axes aligned with each other, and has an inner surface of a regular hexagonal pyramid that is reduced downward from the upper opening 5a to form a lower opening 5b, and the lower opening 5b is a regular hexagonal bar. lO
It has a small gap following the leaf spring 4C, and its sides are deviated by about 36074Xn degrees as the number of sides fn of a regular polygon, that is, about 15 degrees in the case of a regular hexagon. This means that the regular hexagonal frame 1O, which hangs down under its own weight in a rotatable state from the upper opening 5a, is at the angle of approximately 360/4Xn degrees while its tip passes through the regular polygonal guide portion 5, that is, in the embodiment. This is because we have learned through experiments that in a regular hexagon like this, the guide is rotated by about 15 degrees.
また下開口５ｂは同形の正六角形の収納穴２に接続して
いる。Further, the lower opening 5b is connected to the same regular hexagonal storage hole 2.

えながら収納穴２に収納される。When the regular hexagonal rod is suspended in the direction of the arrow (A) with 10% of its own weight toward the container 1 placed vertically below the regular hexagonal frame 10, the tip of the regular hexagonal frame 10 becomes the direction setting portion of the double plate spring 4c,
Contact 4c. At that time, as shown in FIG. 6, the diagonal line passing through the center of the regular hexagonal frame 10 is perpendicular to both leaf springs 4C, 4C, or as shown in FIG. Except for the cases in which the regular hexagonal frame 1G is in contact with the leaf springs 4c and 4c, rotational force is applied to the regular hexagonal frame 1G by the elastic force P of the leaf springs 4c and 4c, and the regular hexagonal frame 10 is rotated. , as shown in FIG. 7, the opposite sides of the regular hexagonal frame 10 are in a stable position where they are in contact with the respective spring plates 4c, 4cK of the orientation setting part, that is, the regular hexagonal frame 10 is at a position δ from the opening ol of the storage hole 2. (50k) Fig. 6. Even when the position is set and the rotational force is not applied from the direction setting part 4 and the direction remains as it is, the regular hexagonal rod 10 is of course located in the storage hole. The position is deviated by about 15 degrees from 2. Furthermore, when the regular hexagonal frame 10 is allowed to hang down under its own weight, the tip of the regular hexagonal frame 10 is rotated by about 15 degrees while passing through the regular polygonal guide part 5, and during this time, both leaf springs 4c, 4c are slightly tilted back. It is stored in the storage hole 2 while giving some protection.

A position offset by about 360/4 x n degrees, that is, about 18 degrees, with respect to two sides sandwiching one apex angle of the storage hole τ, and a position offset by about 18 degrees from the two sides sandwiching one apex angle of the storage hole τ. They are also arranged to be offset by about 18 degrees with respect to the opposing sides so that each side forms one side of a regular pentagon. The reason why the three leaf springs 4'c are arranged for the regular polygonal storage hole lK with odd numbered sides is to ensure that the position of the regular polygonal bar with odd numbered sides in the orientation setting part I is maintained.

They may be arranged sequentially with their axes aligned and configured separately from the container 1. In this case, the regular polygonal rod 10 can also be stored in the container by aligning the polygonal storage hole 2 of the container with the regular polygon guide portion 5 in advance.
