Description

この発明は、例えば宇宙船に収納状態で搭載され、軌道上にて展開する太陽電池パネルやフェーズドアンテナ等の平面、又は大型アンテナや太陽光集光板等の曲面を構成するような展開構造物における動力伝達機構に関するものである。 The present invention is, for example, in a deployment structure that is mounted in a spacecraft and accommodates a flat surface such as a solar cell panel or a phased antenna that is deployed in orbit, or a curved surface such as a large antenna or a solar collector plate. The present invention relates to a power transmission mechanism.

従来の宇宙用展開構造物は、複数個のパネルが一列となるように隣接するパネル同士をヒンジにより連結されて構成された複数個のパネル列を有し、複数個のパネル列が隣りのパネル列と展開方向を異なるようにパネル同士をヒンジにより連結されている。そして、各パネル列は、山折りと谷折りとを交互に繰り返す収納形状となるようにパネル間がヒンジにより連結されている。さらに、パネル列を構成するパネルは、同期機構により同期して動作し、収納形状から展開形状に展開される（例えば、特許文献１参照）。 A conventional space deployment structure has a plurality of panel rows formed by connecting adjacent panels with hinges so that the plurality of panels are arranged in a row, and the plurality of panel rows are adjacent panels. The panels are connected to each other by hinges so that the rows and the development directions are different. And each panel row | line | column is connected with the hinges so that it may become the storage shape which repeats a mountain fold and a valley fold alternately. Furthermore, the panel which comprises a panel row | line | column operate | moves synchronously with a synchronizing mechanism, and is expand | deployed from a storage shape to a deployment shape (for example, refer patent document 1).

この種の宇宙用展開構造物では、宇宙でのパネル列の展開動作が確実に行われるように、地上でのパネル列の展開動作試験が行われる。このパネル列の展開動作試験には、パネル列の収納動作が付随する。また、パネル列を展開させてパネルの評価試験が行われる。
従来の宇宙用展開構造物では、パネル列を構成するパネルが同期機構により同期して動作するように構成されているので、太陽電池パネルのような自動収納できない展開構造物の場合には、複数の作業者が展開されたパネル列の周りに立ち、人手により各パネルの動作を同期させつつ収納する必要があり、収納作業効率が低下していた。また、近年の太陽電池パネルでは、各パネル間の角度を１８０度と異なる角度に展開させる場合がある。このような場合には、パネル列を構成する各パネルの動作を同期させつつ収納することがさらに困難となり、収納作業効率がさらに低下してしまう。
また、個々のパネルの評価試験を実施する場合でも、パネル列を構成する全パネルを展開状態に展開してパネルの評価試験を実施しなければならず、評価試験の作業性が悪化してしまっていた。 In this type of space deployment structure, a panel row deployment operation test on the ground is performed so that the panel row deployment operation in space is performed reliably. The panel row unfolding operation test is accompanied by a panel row storing operation. Moreover, the panel evaluation test is performed by expanding the panel row.
In the conventional space deployment structure, since the panels constituting the panel row are configured to operate in synchronization by a synchronization mechanism, in the case of a deployment structure such as a solar panel that cannot be automatically stored, a plurality of It is necessary for the workers to stand around the deployed panel row and store them while the operation of each panel is synchronized manually, which reduces the storage work efficiency. In recent solar cell panels, the angle between the panels may be expanded to an angle different from 180 degrees. In such a case, it becomes more difficult to store the panels constituting the panel row while synchronizing the operations, and the storage work efficiency is further reduced.
Even when an evaluation test is performed on each panel, all the panels constituting the panel row must be expanded and the panel evaluation test must be performed, which deteriorates the workability of the evaluation test. It was.

この発明は、上記課題を解決するためになされたもので、パネル列を構成するパネル間の動力伝達機構に動力の伝達／非伝達を切り換える同期／非同期切り換え手段を設け、パネル列の収納動作時或いは展開動作時に動力伝達機構による動力伝達を止め、パネルを非同期に動作できるようにし、パネル列の収納作業性を向上させることができるとともに、所望のパネルのみを展開させて評価試験を行えるようにした展開構造物の動力伝達機構を得ることを目的とする。 The present invention has been made in order to solve the above-described problem. A synchronous / asynchronous switching means for switching between transmission and non-transmission of power is provided in a power transmission mechanism between panels constituting the panel row, and when the panel row is stored. Alternatively, the power transmission by the power transmission mechanism can be stopped during the unfolding operation so that the panels can be operated asynchronously, the panel work can be improved, and the evaluation test can be performed by deploying only the desired panel. It aims at obtaining the power transmission mechanism of the developed structure.

この発明による展開構造物の動力伝達機構は、複数個のパネルが、隣接する該パネル同士をヒンジにより連結されて一続きのパネル列となるように構成され、それぞれの該ヒンジの部位で山折りと谷折りとを交互に繰り返して折り畳まれた収納状態と、隣接する該パネル間の展開角度を設定された角度となるように展開された展開状態と、をとる展開構造物の動力伝達機構である。１個置きの上記パネルで構成される一方のパネル群の各パネルには、プーリがその軸心を当該パネルに取り付けられている上記各ヒンジの回転軸心に一致させて、かつ、当該パネルから該各ヒンジの回転軸心の方向の一側に延出するように取り付けられ、１個置きの上記パネルで構成される他方のパネル群の各パネルには、プーリがその軸心を当該パネルに取り付けられている上記各ヒンジの回転軸心に一致させて、かつ、当該パネルから該各ヒンジの回転軸心の方向の他側に延出するように取り付けられている。上記一方のパネル群を構成する隣り合うパネル同士が、それぞれ同期ワイヤを隣り合う上記プーリ対に緊張状態に掛け渡して連結され、かつ、上記他方のパネル群を構成する隣り合うパネル同士が、それぞれ上記同期ワイヤを隣り合う上記プーリ対に緊張状態に掛け渡して連結されている。上記同期ワイヤが掛け渡された上記プーリ対の一方のプーリは、当該パネルに固定状態又は軸心周りに回転自在に取り付けられ、かつ、他方のプーリは、当該パネルに軸心周りに回転自在に取り付けられている。さらに、当該パネルに軸心周りに回転自在に取り付けられた上記プーリは、同期／非同期切り換え手段により当該パネルに対する回転状態と回転阻止状態とが切り換えられるように構成されている。 The power transmission mechanism of the unfolded structure according to the present invention is configured such that a plurality of panels are connected to each other by hinges to form a series of panel rows. A power transmission mechanism of the unfolding structure that takes a folded state in which the folding angle is alternately repeated and a folded state, and a unfolded state in which the unfolded angle between the adjacent panels is set to a set angle. is there. In each panel of one panel group composed of every other panel, a pulley has its axis aligned with the rotational axis of each hinge attached to the panel, and from the panel A pulley is attached to each panel of the other panel group, which is mounted so as to extend to one side in the direction of the rotational axis of each hinge, and is composed of every other panel. It is attached so as to coincide with the rotation axis of each of the attached hinges and to extend from the panel to the other side in the direction of the rotation axis of each of the hinges. Adjacent panels composing the one panel group are connected in tension to the pulley pair adjacent to each other, and adjacent panels composing the other panel group are respectively connected. The synchronous wire is connected to the adjacent pulley pair in a tensioned state. One pulley of the pair of pulleys around which the synchronization wire is stretched is fixedly attached to the panel or rotatably around the axis, and the other pulley is rotatable around the axis on the panel. It is attached. Further, the pulley attached to the panel so as to be rotatable around the axis is configured to be switched between a rotation state and a rotation prevention state with respect to the panel by a synchronous / asynchronous switching means.

この発明によれば、パネル列を展開状態から収納させる際に、同期／非同期切り換え手段により少なくとも一方のプーリを自身が取り付けられているパネルに対して回転状態に切り換える。そこで、パネル列の収納動作時に、パネルの収納動作に連動して他方のプーリに発生する回転トルクが同期ワイヤを介して一方のプーリに伝達されても、一方のプーリは自身が取り付けられているパネルに対して回転し、当該パネルには伝達されない。これにより、パネル列を構成する各パネルを単独に動作させることができ、パネル列を少人数で簡易に収納することができる。また、パネル列を収納状態から展開させる際に、同期／非同期切り換え手段により所定のプーリを回転状態に切り換え、試験評価対象のパネルを単独で動作させるようにできる。そこで、評価試験対象のパネルのみを展開して、評価試験を行うことができる。 According to the present invention, when the panel row is housed from the unfolded state, at least one pulley is switched to the rotating state with respect to the panel to which it is attached by the synchronous / asynchronous switching means. Therefore, even when the rotational torque generated in the other pulley in conjunction with the panel storage operation is transmitted to one pulley via the synchronization wire during the panel storage operation, one pulley is attached to itself. It rotates relative to the panel and is not transmitted to the panel. Thereby, each panel which comprises a panel row | line | column can be operated independently, and a panel row | line can be easily accommodated with a small number of people. Further, when the panel row is expanded from the housed state, the predetermined pulley is switched to the rotating state by the synchronous / asynchronous switching means, and the panel to be tested can be operated independently. Therefore, the evaluation test can be performed by developing only the panel to be evaluated.

図１において、展開構造物１は、例えば宇宙船などの本体部２と、複数個のパネル３と、本体部２とパネル３とを連結するヒンジ４と、複数個のパネル３が一列（一続き）のパネル列となるように隣り合うパネル３同士を連結するヒンジ５と、パネル列を構成するパネル３に展開力および収納力を伝達する後述する動力伝達機構と、を備えている。 In FIG. 1, a deployment structure 1 includes a main body 2 such as a spacecraft, a plurality of panels 3, a hinge 4 that connects the main body 2 and the panel 3, and a plurality of panels 3. A hinge 5 that connects adjacent panels 3 so as to form a panel row, and a power transmission mechanism that will be described later and that transmits a deployment force and a storage force to the panels 3 constituting the panel row.

パネル３は、図２に示されるように、例えば矩形平板状に作製された太陽電池パネルである。各パネル３は、相対する両側面の中央部で、対応するパネル３の側面の中央部にヒンジ５により連結されている。そして、ヒンジ５の回転軸５ａの軸方向は、パネル３の側面の長さ方向に一致している。これにより、複数個のパネル３は、一列のパネル列を構成するようにヒンジ５により連結されている。パネル列の一端のパネル３は、他方の側面の中央部で、ヒンジ４により本体部２に連結されている。このヒンジ４の回転軸の軸方向は、ヒンジ５の回転軸５ａの軸方向と平行である。そして、パネル列は、一端のパネル３がヒンジ４の回転軸周りに回転自在に本体部２に連結され、隣り合うパネル３がヒンジ５の回転軸５ａ周り回転自在に連結され、図１の（ａ）に示されるように、山折りと谷折りとを交互に繰り返して折り畳まれた収納状態をとる。 As shown in FIG. 2, the panel 3 is a solar cell panel that is manufactured in a rectangular flat plate shape, for example. Each panel 3 is connected to the center part of the side surface of the corresponding panel 3 by a hinge 5 at the center part of the opposite side surfaces. The axial direction of the rotation shaft 5 a of the hinge 5 coincides with the length direction of the side surface of the panel 3. Thereby, the several panel 3 is connected by the hinge 5 so that the panel row of 1 row may be comprised. The panel 3 at one end of the panel row is connected to the main body 2 by a hinge 4 at the center of the other side surface. The axial direction of the rotation axis of the hinge 4 is parallel to the axial direction of the rotation axis 5 a of the hinge 5. In the panel row, the panel 3 at one end is connected to the main body 2 so as to be rotatable around the rotation axis of the hinge 4, and the adjacent panels 3 are connected so as to be rotatable around the rotation axis 5a of the hinge 5, as shown in FIG. As shown in a), the folded state is taken by alternately repeating mountain folds and valley folds.

つぎに、動力伝達機構について、図２乃至図４を参照しつつ説明する。
一対のプーリ取付台６が、図２に示されるように、各パネル３のヒンジ結合された両側面の長さ方向一側縁部にそれぞれ一体に配設されている。
第１プーリ７は、図４に示されるように、有底円筒状の胴部８と、胴部８の先端に一体に形成されたリング状のフランジ部９と、を備えている。この第１プーリ７は、取付ねじ（図示せず）などを用いて胴部８を一側のプーリ取付台６に締着固定されている。この第１プーリ７は、その軸心がヒンジ５の回転軸５ａと同軸となり、かつ、少なくともフランジ部９がパネル３から反ヒンジ５側に延出するようにプーリ取付台６に取り付けられている。この第１プーリ７の軸心は、フランジ部９の中心である。 Next, the power transmission mechanism will be described with reference to FIGS.
As shown in FIG. 2, a pair of pulley mounting bases 6 are integrally disposed on one side edge in the longitudinal direction of both side surfaces of each panel 3 that are hinged.
As shown in FIG. 4, the first pulley 7 includes a bottomed cylindrical barrel portion 8 and a ring-shaped flange portion 9 integrally formed at the tip of the barrel portion 8. In the first pulley 7, the body 8 is fastened and fixed to the pulley mounting base 6 on one side using a mounting screw (not shown) or the like. The first pulley 7 is attached to the pulley mounting base 6 so that its axis is coaxial with the rotation shaft 5a of the hinge 5 and at least the flange portion 9 extends from the panel 3 to the anti-hinge 5 side. . The axis of the first pulley 7 is the center of the flange portion 9.

第２プーリ１０は、図３に示されるように、固定部としての有底円筒状の胴部１１と、リング状のフランジ部１３が円筒状の筒部１４の先端に一体に形成され、筒部１４を胴部１１に同軸、かつ、外嵌状態に装着され、胴部１１に回転自在に取りつけられた可動部１２と、可動部１２の胴部１１からの抜けを防止する抜け止め部材１５と、連結部材としての固定ピン１６と、固定ピン１６の抜けを防止するナット１７と、を備えている。この第２プーリ１０は、取付ねじ（図示せず）などを用いて胴部１１を他側のプーリ取付台６に締着固定されている。この第２プーリ１０は、その軸心がヒンジ５の回転軸５ａと同軸となり、かつ、少なくともフランジ部１３がパネル３から反ヒンジ５側に延出するようにプーリ取付台６に取り付けられている。この第２プーリ１０の軸心は、胴部１１（可動部１２）の中心である。
そして、胴部１１には、穴方向を軸心と直交する固定側穴としての一対の貫通穴１１ａが穿設され、筒部１４には、高さ位置を貫通穴１１ａと同じくして、穴方向を軸心と直交する可動側穴としての一対の貫通穴１４ａが穿設されている。そして、固定ピン１６が貫通穴１１ａ，１４ａに挿入されて、可動部１２の胴部１１に対する回転が阻止される。ここで、貫通穴１１ａ，１４ａ、固定ピン１６およびナット１７が同期／非同期切り換え手段を構成している。 As shown in FIG. 3, the second pulley 10 has a bottomed cylindrical barrel portion 11 as a fixed portion and a ring-shaped flange portion 13 integrally formed at the tip of the cylindrical tube portion 14. The movable part 12 is mounted coaxially and externally on the body part 11 and is rotatably attached to the body part 11, and a retaining member 15 that prevents the movable part 12 from coming off from the body part 11. And a fixing pin 16 as a connecting member, and a nut 17 for preventing the fixing pin 16 from coming off. The second pulley 10 is fastened and fixed to the pulley mounting base 6 on the other side by using a mounting screw (not shown) or the like. The second pulley 10 is attached to the pulley mounting base 6 so that its axis is coaxial with the rotation shaft 5a of the hinge 5 and at least the flange portion 13 extends from the panel 3 to the anti-hinge 5 side. . The axis of the second pulley 10 is the center of the trunk portion 11 (movable portion 12).
The body portion 11 is provided with a pair of through holes 11a serving as fixed side holes whose hole direction is orthogonal to the axis, and the cylindrical portion 14 has the same height as the through hole 11a. A pair of through holes 14a are formed as movable side holes whose directions are perpendicular to the axis. And the fixed pin 16 is inserted in the through holes 11a and 14a, and rotation with respect to the trunk | drum 11 of the movable part 12 is blocked | prevented. Here, the through holes 11a and 14a, the fixing pin 16 and the nut 17 constitute a synchronous / asynchronous switching means.

パネル列は、パネル３のプーリ取付台６の配設側を互い違いにしてヒンジ５により連結されている。そして、無端状の同期ワイヤ１８が、各パネル３の両側に位置する一側のパネル３の第１プーリ７のフランジ部９と、他側のパネル３の第２プーリ１０のフランジ部１３とに緊張状態に掛け渡されている。ここで、第１プーリ７のフランジ部９の直径（プーリ径）は、第２プーリ１０のフランジ部１３の直径（プーリ径）に等しい。 The panel rows are connected by hinges 5 with the arrangement side of the pulley mounting base 6 of the panel 3 being staggered. An endless synchronization wire 18 is connected to the flange portion 9 of the first pulley 7 of the panel 3 on one side and the flange portion 13 of the second pulley 10 of the other panel 3 located on both sides of each panel 3. It is stretched over tension. Here, the diameter (pulley diameter) of the flange portion 9 of the first pulley 7 is equal to the diameter (pulley diameter) of the flange portion 13 of the second pulley 10.

そこで、パネル列は、本体部２側から１番目と３番目のパネル３の対、３番目と５番目のパネル３の対、５番目と７番目のパネル３の対、７ａ番目と９番目のパネル３の対、９番目と１１番目のパネル３の対が、それぞれ動力伝達機構により連結され、本体部２と２番目のパネル３の対、２番目と４番目のパネル３の対、４番目と６番目のパネル３の対、６番目と８番目のパネル３の対、８番目と１０番目のパネル３の対が、それぞれ動力伝達機構により連結されている。なお、パネル列の１番目のパネル３の本体部２側と、最先端に位置するパネル３の先端側とには、第１プーリ７又は第２プーリ１０が不要となる。 Therefore, the panel row includes the first and third panel 3 pairs, the third and fifth panel 3 pairs, the fifth and seventh panel 3 pairs, the 7ath and the ninth panel from the main body 2 side. The pair of panels 3, the pair of the ninth and eleventh panels 3 are connected by the power transmission mechanism, respectively, the pair of the main body 2 and the second panel 3, the pair of the second and fourth panels 3, and the fourth The pair of the sixth panel 3, the pair of the sixth and eighth panels 3, and the pair of the eighth and tenth panels 3 are connected by a power transmission mechanism. In addition, the 1st pulley 7 or the 2nd pulley 10 becomes unnecessary in the main-body part 2 side of the 1st panel 3 of a panel row | line | column, and the front end side of the panel 3 located in the forefront.

ついで、パネル列の動力伝達機構による動作について図５および図６を参照しつつ説明する。
まず、固定ピン１６が貫通穴１１ａ，１４ａに挿入されている状態では、パネル３がヒンジ５の回転軸５ａ周りに回転すると、第１プーリ７がパネル３の回転に連動して回転軸５ａ周りに回転する。そして、第１プーリ７の回転トルクが同期ワイヤ１８を介して１個離れたパネル３の第２プーリ１０に伝達され、当該パネル３がヒンジ５の回転軸５ａ周りに回転する。つまり、１個離れたパネル３の対が、互いに拘束状態となり、図５に示されるように、同期して展開、あるいは収納動作する。
また、固定ピン１６が貫通穴１１ａ，１４ａから取り外されている状態では、パネル３がヒンジ５の回転軸５ａ周りに回転すると、第１プーリ７がパネル３の回転に連動して回転軸５ａ周りに回転する。そして、第１プーリ７の回転トルクが同期ワイヤ１８を介して１個離れたパネル３の第２プーリ１０に伝達される。この時、第２プーリ１０の可動部１２が胴部１１、即ちプーリ取付台６に対して回転し、第１プーリ７の回転トルクは、当該パネル３に伝達されない。つまり、パネル３の対は、固定ピン１６を取り外すことにより、互いの拘束状態が解除され、図６に示されるように、独自にヒンジ５の回転軸５ａ周りに回転できる。
このように、固定ピン１６の抜き差しにより、パネル３の対の同期／非同期状態（拘束状態／非拘束状態）が切り換えられる。 Next, the operation of the panel row power transmission mechanism will be described with reference to FIGS.
First, in a state where the fixing pin 16 is inserted into the through holes 11 a and 14 a, when the panel 3 rotates around the rotation axis 5 a of the hinge 5, the first pulley 7 moves around the rotation axis 5 a in conjunction with the rotation of the panel 3. Rotate to. Then, the rotational torque of the first pulley 7 is transmitted to the second pulley 10 of the panel 3 separated by one via the synchronization wire 18, and the panel 3 rotates around the rotation axis 5 a of the hinge 5. That is, the pair of panels 3 that are separated from each other are in a restrained state, and as shown in FIG.
When the fixing pin 16 is removed from the through holes 11 a and 14 a, when the panel 3 rotates around the rotation axis 5 a of the hinge 5, the first pulley 7 moves around the rotation axis 5 a in conjunction with the rotation of the panel 3. Rotate to. Then, the rotational torque of the first pulley 7 is transmitted via the synchronization wire 18 to the second pulley 10 of the panel 3 separated by one. At this time, the movable part 12 of the second pulley 10 rotates relative to the body part 11, that is, the pulley mounting base 6, and the rotational torque of the first pulley 7 is not transmitted to the panel 3. That is, the pair of panels 3 is released from the mutual restraint state by removing the fixing pin 16 and can independently rotate around the rotation axis 5a of the hinge 5 as shown in FIG.
As described above, the synchronous / asynchronous state (constrained state / unconstrained state) of the pair of the panels 3 is switched by inserting / removing the fixing pin 16.

このように構成された展開構造物は、図１の（ａ）に示されるように、パネル３が山折りと谷折りを交互に繰り返すように折り畳まれて収納される。そして、パネル列の最先端のパネル３（本体部２から最も離れたパネル３）を展開方向に移動させると、図１の（ｂ）に示されるように、各パネル３が同期して展開する。この時、各パネル３の展開角度は等しい。さらに、パネル列の最先端のパネル３を展開方向に移動させると、図１の（ｃ）に示されるように、各パネル３の展開角度が１８０度となり、展開動作が終了する。
そして、全ての固定ピン１６を取り外してパネル３間を同期状態から非同期状態に切り換えることにより、例えば、パネル列を構成するパネル３を個々にヒンジ４，５の回転軸周りに回転させ、図１の（ａ）に示される収納状態に収納することができる。 As shown in FIG. 1A, the unfolded structure thus configured is housed by being folded so that the panel 3 alternately repeats the mountain fold and the valley fold. When the most advanced panel 3 in the panel row (the panel 3 farthest from the main body 2) is moved in the deployment direction, the panels 3 are deployed in synchronization as shown in FIG. . At this time, the deployment angle of each panel 3 is equal. Further, when the most advanced panel 3 in the panel row is moved in the developing direction, as shown in FIG. 1C, the developing angle of each panel 3 becomes 180 degrees, and the developing operation ends.
Then, by removing all the fixing pins 16 and switching between the panels 3 from the synchronous state to the asynchronous state, for example, the panels 3 constituting the panel row are individually rotated around the rotation axes of the hinges 4 and 5. It can be stored in the storage state shown in (a).

また、パネル３の評価試験を行う場合、評価試験すべきパネル３のみを非同期状態とするように固定ピン１６を取り外す。これにより、図１の（ｄ）に示されるように、評価試験すべきパネル３のみを展開状態にすることができる。従って、全てのパネル３を展開状態にすることなく、対象のパネル３のみの評価試験を実施することができる。 Moreover, when performing the evaluation test of the panel 3, the fixing pin 16 is removed so that only the panel 3 to be evaluated is in an asynchronous state. Thereby, as shown in (d) of Drawing 1, only panel 3 which should be evaluated can be made into a deployment state. Therefore, the evaluation test of only the target panel 3 can be performed without setting all the panels 3 in the unfolded state.

ここで、第１プーリ７のフランジ部９の直径（プーリ径）と、第２プーリ１０のフランジ部１３の直径（プーリ径）とを異ならせることにより、パネル３の展開角度を適宜設定することができる。
このように構成された展開構造物では、図７の（ａ）に示される収納状態から展開させると、各パネル３は、図７の（ｂ）に示されるように、第１プーリ７と第２プーリ１０とのプーリ比に応じて、展開角度を異ならせて展開する。そして、各パネル３は、図７の（ｃ）に示されるように、第１プーリ７と第２プーリ１０とのプーリ比により設定される展開角度に展開される。
そして、この展開状態では、個々のパネル３の展開角度が異なることから、パネル３の対が同期状態（拘束状態）であると、極めて煩雑な収納作業となる。しかし、パネル３の対を非同期状態（非拘束状態）とすることにより、簡易に収納することができる。 Here, the deployment angle of the panel 3 is appropriately set by making the diameter (pulley diameter) of the flange portion 9 of the first pulley 7 different from the diameter (pulley diameter) of the flange portion 13 of the second pulley 10. Can do.
In the unfolded structure configured as described above, when the panel 3 is unfolded from the storage state illustrated in FIG. 7A, each panel 3 is connected to the first pulley 7 and the first pulley 7 as illustrated in FIG. 7B. Depending on the pulley ratio with the two pulleys 10, the deployment angle is varied. Each panel 3 is deployed at a deployment angle set by a pulley ratio between the first pulley 7 and the second pulley 10 as shown in FIG.
In this unfolded state, the unfolding angles of the individual panels 3 are different. Therefore, if the pair of panels 3 is in a synchronized state (restrained state), it is an extremely complicated storing operation. However, the pair of panels 3 can be easily housed by placing them in an asynchronous state (unconstrained state).

FIG. 10 is a sectional view for explaining the operation of the synchronous / asynchronous switching means in the transmission mechanism, and FIG. 10 is a process sectional view for explaining the switching method from the synchronous state to the asynchronous state in the power transmission mechanism of the developed structure according to Embodiment 2 of the present invention. FIG.

図８および図９において、同期／非同期切り換え手段は、円筒状のガイド体２０と、ガイド体２０の外周面に案内されて、ガイド体２０の軸方向に摺動自在にガイド体２０の両端に外嵌状態に装着された連結部材としての一対のピン部２１と、ガイド体２０に外嵌状態に装着されて一対のピン部２１間に縮設されたばね部材２２と、を備えている。そして、細長のスリット２１ａがガイド体２０の軸方向に延びるように各ピン部２１に形成されている。さらに、ピン２３がスリット２１ａから延出するようにガイド体２０に突設されている。このピン２３は、スリット２１ａの細長の長手方向の両壁面に係合して、ピン部２１の伸縮量を規定している。 8 and 9, the synchronous / asynchronous switching means is guided to the cylindrical guide body 20 and the outer peripheral surface of the guide body 20, and is slidable in the axial direction of the guide body 20 at both ends of the guide body 20. A pair of pin portions 21 serving as connecting members mounted in an external fitting state, and a spring member 22 mounted on the guide body 20 in an external fitting state and contracted between the pair of pin portions 21 are provided. An elongated slit 21 a is formed in each pin portion 21 so as to extend in the axial direction of the guide body 20. Furthermore, the pin 23 protrudes from the guide body 20 so as to extend from the slit 21a. The pin 23 is engaged with both long and slender longitudinal wall surfaces of the slit 21 a to define the amount of expansion and contraction of the pin portion 21.

このように構成された同期／非同期切り換え手段は、ピン部２１を押し縮めた状態で胴部１１内に挿入される。そして、ピン部２１を貫通穴１１ａに合わせて、ピン部２１の押し縮めるのを止める。これにより、ピン部２１がばね部材２２の付勢力によりガイド体２０の軸方向外方に移動され、貫通穴１１ａ内に挿入され、図９の（ｂ）に示されるように、同期／非同期切り換え手段が装着される。この状態では、ピン部２１が貫通穴１１ａ内にのみ挿入されているので、筒部１４は胴部１１に対して回転自在になっている。即ち、可動部１２がプーリ取付台６に対して回転自在となっており、パネル３の対は非同期状態となっている。
そして、可動部１２が回転し、貫通穴１４ａが貫通穴１１ａの位置にくると、図９の（ａ）に示されるように、ピン部２１はばね部材２２の付勢力によりガイド体２０の軸方向外方に押し出され、貫通穴１４ａ内に挿入される。この時、ピン２３はスリット２１ａの壁面に当接し、ピン部２１のそれ以上の延出が阻止される。この状態では、ピン部２１が貫通穴１１ａ，１４ａ内に挿入されているので、筒部１４は胴部１１に対して回転できない。即ち、可動部１２がプーリ取付台６に対して固定され、パネル３の対は同期状態となっている。 The synchronous / asynchronous switching means configured as described above is inserted into the trunk portion 11 with the pin portion 21 being compressed. And the pin part 21 is match | combined with the through-hole 11a, and the compression of the pin part 21 is stopped. As a result, the pin portion 21 is moved outward in the axial direction of the guide body 20 by the urging force of the spring member 22, and is inserted into the through hole 11a. As shown in FIG. 9B, synchronous / asynchronous switching is performed. Means are mounted. In this state, since the pin portion 21 is inserted only into the through hole 11 a, the cylindrical portion 14 is rotatable with respect to the trunk portion 11. That is, the movable part 12 is rotatable with respect to the pulley mounting base 6, and the pair of panels 3 is in an asynchronous state.
When the movable portion 12 rotates and the through hole 14a comes to the position of the through hole 11a, as shown in FIG. 9 (a), the pin portion 21 is pivoted by the spring member 22 to the shaft of the guide body 20. Pushed outward in the direction and inserted into the through hole 14a. At this time, the pin 23 comes into contact with the wall surface of the slit 21a, and further extension of the pin portion 21 is prevented. In this state, since the pin portion 21 is inserted into the through holes 11 a and 14 a, the tube portion 14 cannot rotate with respect to the trunk portion 11. That is, the movable portion 12 is fixed to the pulley mounting base 6 and the pair of panels 3 are in a synchronized state.

つぎに、動力伝達機構の同期状態から非同期状態への切り換え方法について図１０を参照しつつ説明する。なお、図１０中、同期解除治具２４は、貫通穴１４ａに挿入できる大きさの凸部２４ａが先端に設けられている。
まず、図１０の（ａ）に示される同期状態では、ピン部２１が貫通穴１１ａ，１４ａ内に挿入されている。
ついで、図１０の（ｂ）に示されるように、同期解除治具２４の凸部２４ａを両側から各ピン部２１の先端に押し当て、ピン部２１を押し込む。これにより、ピン部２１はばね部材２２の付勢力に抗してガイド体２０の外周面上を摺動しつつ移動し、貫通穴１４ａから抜ける。
そして、図１０の（ｃ）に示されるように、筒部１４を僅かに回転させる。これにより、貫通穴１４ａの穴中心が貫通穴１１ａの穴中心から外れる。そこで、図１０の（ｄ）に示されるように同期解除治具２４を取り外し、同期状態から非同期状態への切り替えが完了する。 Next, a method for switching the power transmission mechanism from the synchronous state to the asynchronous state will be described with reference to FIG. In FIG. 10, the synchronization release jig 24 is provided with a convex portion 24 a at a tip that can be inserted into the through hole 14 a.
First, in the synchronized state shown in FIG. 10A, the pin portion 21 is inserted into the through holes 11a and 14a.
Next, as shown in FIG. 10B, the convex portion 24 a of the synchronization release jig 24 is pressed against the tip of each pin portion 21 from both sides, and the pin portion 21 is pushed in. Accordingly, the pin portion 21 moves while sliding on the outer peripheral surface of the guide body 20 against the urging force of the spring member 22, and comes out of the through hole 14a.
And as FIG.10 (c) shows, the cylinder part 14 is rotated a little. Thereby, the hole center of the through hole 14a deviates from the hole center of the through hole 11a. Therefore, as shown in FIG. 10D, the synchronization release jig 24 is removed, and the switching from the synchronous state to the asynchronous state is completed.

この実施の形態２によれば、ピン部２１を貫通穴１１ａ，１４ａ内に挿入させる方向に付勢するばね部材２２を備えているので、ピン部２１を押圧してピン部２１を貫通穴１４ａから押し出して同期状態を解除でき、貫通穴１１ａ，１４ａの穴中心が一致したときに、ピン部２１がばね部材２２の付勢力により貫通穴１１ａ，１４ａに挿入されて同期状態を確保でき、同期状態と非同期状態との切り換え作業が簡単となる。 According to the second embodiment, since the spring member 22 that urges the pin portion 21 in the direction in which the pin portion 21 is inserted into the through holes 11a and 14a is provided, the pin portion 21 is pressed to cause the pin portion 21 to pass through the through hole 14a. When the hole centers of the through holes 11a and 14a coincide with each other, the pin portion 21 is inserted into the through holes 11a and 14a by the urging force of the spring member 22 to ensure the synchronized state. Switching between the state and the asynchronous state is simplified.

ここで、同期解除治具２４は凸部２４ａの突出高さを貫通穴１４ａの深さ（筒部１４の厚み）と同等に形成しておけば、同期解除治具２４でピン部２１を押圧した際に、凸部２４ａが胴部１１の貫通穴１１ａまで入り込まないので、同期状態から非同期状態への切り替え作業が簡易となる。
また、パネル列が収納状態となっているときに、両者の穴中心が一致するように貫通穴１１ａ，１４ａを形成しておけば、展開状態から収納状態に収納することで、ピン部２１がばね部材２２の付勢力により自動的に貫通穴１１ａ，１４ａに挿入される。従って、展開構造物の展開動作試験や評価試験を行っても、展開構造物を一旦展開状態から収納状態に戻すことで、自動的に同期状態に復帰する。そこで、展開構造物が宇宙船に収納状態で搭載されて打ち上げられ、軌道上にて展開しようとした際に、展開構造物を確実に展開できる。即ち、展開構造物が軌道上で展開できないという不具合は確実に解消される。 Here, the synchronization release jig 24 presses the pin portion 21 with the synchronization release jig 24 if the protruding height of the convex portion 24a is formed to be equal to the depth of the through hole 14a (the thickness of the cylindrical portion 14). In this case, since the convex portion 24a does not enter the through hole 11a of the trunk portion 11, the switching operation from the synchronous state to the asynchronous state is simplified.
Further, when the through holes 11a and 14a are formed so that the hole centers coincide when the panel row is in the storage state, the pin portion 21 is stored in the storage state from the expanded state. The spring member 22 is automatically inserted into the through holes 11a and 14a by the urging force of the spring member 22. Therefore, even if a deployment operation test and an evaluation test of the deployment structure are performed, the deployment structure is automatically returned to the synchronized state by returning it from the deployed state to the stored state. Therefore, when the unfolding structure is mounted and launched in the spacecraft and is about to unfold in orbit, the unfolding structure can be reliably unfolded. That is, the problem that the unfolding structure cannot be unfolded on the track is surely solved.

実施の形態３．
図１１はこの発明の実施の形態３に係る展開構造物の動力伝達機構における同期／非同期切り換え手段の構成を説明する断面図である。
図１１において、同期／非同期切り換え手段は、有底円筒状のガイド体２５と、ガイド体２５の内周面に案内されて、ガイド体２５の軸方向に摺動自在にガイド体２５内に装着された連結部材としての円柱状のピン部２６と、ガイド体２５内に装着されてピン部２６をガイド体２５から延出させるように付勢するばね部材２７と、を備えている。そして、細長のスリット２５ａがガイド体２５の軸方向に延びるようにガイド体２５に形成されている。さらに、ピン２８がスリット２５ａから延出するようにピン部２６に突設されている。このピン２８は、スリット２５ａの細長の長手方向の両壁面に係合して、ピン部２６のガイド体２５からの伸縮量を規定している。
なお、図１１において、左側の同期／非同期切り換え手段は同期状態を示し、右側の同期／非同期切り換え手段は非同期状態を示している。 Embodiment 3 FIG.
FIG. 11 is a cross-sectional view for explaining the configuration of the synchronous / asynchronous switching means in the power transmission mechanism of the developed structure according to Embodiment 3 of the present invention.
In FIG. 11, the synchronous / asynchronous switching means is mounted in the guide body 25 so as to be slidable in the axial direction of the guide body 25 guided by the bottomed cylindrical guide body 25 and the inner peripheral surface of the guide body 25. A cylindrical pin portion 26 serving as a connecting member, and a spring member 27 that is mounted in the guide body 25 and urges the pin portion 26 to extend from the guide body 25 are provided. An elongated slit 25 a is formed in the guide body 25 so as to extend in the axial direction of the guide body 25. Further, the pin 28 protrudes from the pin portion 26 so as to extend from the slit 25a. The pin 28 is engaged with both long and slender longitudinal wall surfaces of the slit 25 a to define the amount of expansion and contraction of the pin portion 26 from the guide body 25.
In FIG. 11, the left synchronous / asynchronous switching means indicates a synchronous state, and the right synchronous / asynchronous switching means indicates an asynchronous state.

このように構成された同期／非同期切り換え手段は、ガイド体２５がその穴位置を貫通穴１４ａに一致させて筒部１４の外周面に固着されている。
そして、貫通穴１１ａ，１４ａの穴中心が一致すると、ばね部材２７の付勢力によりピン部２６がガイド体２５から延出し、貫通穴１１ａ，１４ａに挿入される。この時、ピン２８がスリット２５ａのガイド体２５の開口側の壁面に当接し、ピン部２６のガイド体２５からの延出が阻止される。この状態では、ピン部２６が貫通穴１１ａ，１４ａに挿入されているので、筒部１４は胴部１１に対して回転できない。即ち、可動部１２がプーリ取付台６に対して固定され、パネル３の対は同期状態となっている。
また、ピン２８をスリット２５ａに沿ってガイド体２５の底部側に移動させると、ピン部２６がばね部材２７の付勢力に抗してガイド体２５の底部側に移動し、貫通穴１１ａから抜ける。この状態では、ピン部２６が貫通穴１４ａ内にのみ挿入されているので、筒部１４は胴部１１に対して回転自在になっている。即ち、可動部１２がプーリ取付台６に対して回転自在となっており、パネル３の対は非同期状態となっている。 In the synchronous / asynchronous switching means configured as described above, the guide body 25 is fixed to the outer peripheral surface of the cylindrical portion 14 with its hole position aligned with the through hole 14a.
When the hole centers of the through holes 11a and 14a coincide, the pin portion 26 extends from the guide body 25 by the biasing force of the spring member 27 and is inserted into the through holes 11a and 14a. At this time, the pin 28 comes into contact with the wall surface of the slit 25a on the opening side of the guide body 25, and the extension of the pin portion 26 from the guide body 25 is prevented. In this state, since the pin portion 26 is inserted into the through holes 11 a and 14 a, the tube portion 14 cannot rotate with respect to the body portion 11. That is, the movable portion 12 is fixed to the pulley mounting base 6 and the pair of panels 3 are in a synchronized state.
Further, when the pin 28 is moved along the slit 25a toward the bottom side of the guide body 25, the pin part 26 moves toward the bottom side of the guide body 25 against the urging force of the spring member 27 and comes out of the through hole 11a. . In this state, since the pin portion 26 is inserted only into the through hole 14 a, the cylindrical portion 14 is rotatable with respect to the trunk portion 11. That is, the movable part 12 is rotatable with respect to the pulley mounting base 6, and the pair of panels 3 is in an asynchronous state.

この実施の形態３によれば、ピン部２６を貫通穴１１ａ，１４ａ内に挿入させる方向に付勢するばね部材２７を備えているので、ピン２８をガイド体２５の底部側に移動させてピン部２６を貫通穴１１ａから抜いて同期状態を解除でき、貫通穴１１ａ，１４ａの穴中心が一致したときに、ピン部２６がばね部材２７の付勢力により貫通穴１１ａ，１４ａに挿入されて同期状態を確保でき、同期状態と非同期状態との切り換え作業が簡単となる。
また、この実施の形態３においても、上記実施の形態２と同様に、パネル列が収納状態となっているときに、両者の穴中心が一致するように貫通穴１１ａ，１４ａを形成しておけば、展開構造物が軌道上で展開できないという不具合を確実に解消できる。 According to the third embodiment, since the spring member 27 that urges the pin portion 26 in the direction in which the pin portion 26 is inserted into the through holes 11a and 14a is provided, the pin 28 is moved to the bottom side of the guide body 25 and the pin is moved. The synchronous state can be released by removing the portion 26 from the through hole 11a, and when the hole centers of the through holes 11a and 14a coincide with each other, the pin portion 26 is inserted into the through holes 11a and 14a by the urging force of the spring member 27 and synchronized. The state can be secured, and the switching operation between the synchronous state and the asynchronous state is simplified.
Also in the third embodiment, as in the second embodiment, when the panel row is in the housed state, the through holes 11a and 14a may be formed so that the hole centers coincide with each other. Thus, it is possible to surely solve the problem that the deployable structure cannot be deployed on the track.

実施の形態４．
図１２はこの発明の実施の形態４に係る展開構造物の動力伝達機構における同期状態から非同期状態への切り換え方法を説明する工程断面図である。
図１２において、係止穴２６ａがピン部２６の先端側に凹設され、テーパ面２６ｂがピン部２６の先端部に形成されている。また、有底円筒状のガイド筒３０が開口側を貫通穴１１ａの出口に面するように胴部１１の内壁面に固着されている。そして、係止ピン３１が伸縮自在にガイド筒３０内に装着され、ばね部材３２が係止ピン３１を延出させる方向に付勢するようにガイド筒３０内に縮設されている。また、細長のスリット３０ａがガイド筒３０の軸方向に延びるようにガイド筒３０に形成されている。さらに、ピン３３がスリット３０ａから延出するように係止ピン３１に突設されている。このピン３３は、スリット３０ａの細長の長手方向の両壁面に係合して、係止ピン３１のガイド筒３０からの伸縮量を規定している。ここで、係止穴２６ａ、ガイド筒３０、係止ピン３１およびばね部材３２がラッチ機構を構成している。
なお、他の構成は上記実施の形態３と同様に構成されている。 Embodiment 4 FIG.
FIG. 12 is a process cross-sectional view illustrating a switching method from the synchronous state to the asynchronous state in the power transmission mechanism of the developed structure according to Embodiment 4 of the present invention.
In FIG. 12, a locking hole 26 a is recessed at the tip end side of the pin portion 26, and a tapered surface 26 b is formed at the tip end portion of the pin portion 26. A bottomed cylindrical guide tube 30 is fixed to the inner wall surface of the body 11 so that the opening side faces the outlet of the through hole 11a. Then, the locking pin 31 is mounted in the guide tube 30 so as to be extendable and contracted, and the spring member 32 is contracted in the guide tube 30 so as to be biased in a direction in which the locking pin 31 extends. The elongated slit 30 a is formed in the guide cylinder 30 so as to extend in the axial direction of the guide cylinder 30. Further, the locking pin 31 protrudes from the slit 30a so that the pin 33 extends. The pin 33 engages with both long and slender longitudinal wall surfaces of the slit 30 a to define the amount of expansion and contraction of the locking pin 31 from the guide tube 30. Here, the locking hole 26a, the guide tube 30, the locking pin 31, and the spring member 32 constitute a latch mechanism.
Other configurations are the same as those in the third embodiment.

この実施の形態４では、図１２の（ａ）に示されるように、ピン部２６はばね部材２７の付勢力により貫通穴１４ａ，１１ａ内に挿入される。そして、図１２の（ｂ）に示されるように、このピン部２６の挿入動作に伴って、係止ピン３１がばね部材３２の付勢力に抗してテーパ面２６ｂに沿って押し上げられる。そして、図１２の（ｃ）に示されるように、ピン部２６がさらに挿入され、係止穴２６ａが係止ピン３１の位置までくると、係止ピン３１がばね部材３２の付勢力によりガイド筒３０から押し出され、係止穴２６ａ内に挿入される。これにより、パネル３の対の同期状態が確保される。
また、ピン３３を押し上げて、係止ピン３１を係止穴２６ａから抜き、ついでピン部２６を貫通穴１１ａから引き抜いて、パネル３の対を非同期状態とする。 In the fourth embodiment, as shown in FIG. 12A, the pin portion 26 is inserted into the through holes 14 a and 11 a by the urging force of the spring member 27. Then, as shown in FIG. 12 (b), the locking pin 31 is pushed up along the tapered surface 26 b against the urging force of the spring member 32 as the pin portion 26 is inserted. Then, as shown in FIG. 12C, when the pin portion 26 is further inserted and the locking hole 26 a reaches the position of the locking pin 31, the locking pin 31 is guided by the biasing force of the spring member 32. It is pushed out from the cylinder 30 and inserted into the locking hole 26a. Thereby, the synchronized state of the pair of panels 3 is ensured.
Further, the pin 33 is pushed up, the locking pin 31 is pulled out from the locking hole 26a, and then the pin portion 26 is pulled out from the through hole 11a, so that the pair of panels 3 is brought into an asynchronous state.

このように、この実施の形態４によれば、同期／非同期切り換え手段にラッチ機構を持たせているので、展開構造体を宇宙船に収納状態で搭載して打ち上げても、動力伝達機構の同期状態が確保され、軌道上で展開構造体を確実に展開させることができる。
また、係止ピン３１がガイド筒３０内に伸縮自在に配設され、ばね部材３２が係止ピン３１を延出させるようにガイド筒３０内に縮設されているので、ピン部２６が貫通穴１１ａを挿通し、係止穴２６ａが係止ピン３１の位置に到達すると、係止ピン３１が自動的に係止穴２６ａ内に挿入される。そこで、振動等に起因するパネル３の対の同期状態から非同期状態への移行が確実に阻止される。 Thus, according to the fourth embodiment, since the synchronization / asynchronous switching means is provided with the latch mechanism, even if the deployment structure is mounted in the spacecraft and launched, the synchronization of the power transmission mechanism is achieved. The state is secured, and the deployment structure can be reliably deployed on the track.
Further, the locking pin 31 is disposed in the guide tube 30 so as to be extendable and contractable, and the spring member 32 is contracted in the guide tube 30 so as to extend the locking pin 31, so that the pin portion 26 penetrates. When the locking hole 26a reaches the position of the locking pin 31 through the hole 11a, the locking pin 31 is automatically inserted into the locking hole 26a. Therefore, the transition from the synchronous state of the pair of panels 3 due to vibration or the like to the asynchronous state is reliably prevented.

実施の形態５．
図１３はこの発明の実施の形態５に係る展開構造物の動力伝達機構における第２プーリの構成を説明する断面図である。
図１３において、第２プーリ１０Ａは、プーリ取付台６に締着固定される固定部としての円柱状の軸部３５と、軸部３５に同軸、かつ、外嵌状態に装着されて軸部３５に回転自在に取りつけられた可動部１２と、を備えている。そして、固定側穴としての貫通穴３５ａが高さ位置を貫通穴１４ａと同じくして、穴方向を軸心と直交するように軸部３５に穿設されている。なお、軸部３５には、可動部１２の抜けを防止するフランジ部が形成されている。 Embodiment 5. FIG.
FIG. 13 is a cross-sectional view illustrating the configuration of the second pulley in the power transmission mechanism of the developed structure according to Embodiment 5 of the present invention.
In FIG. 13, the second pulley 10 A includes a columnar shaft portion 35 as a fixing portion that is fastened and fixed to the pulley mounting base 6, and a shaft portion 35 that is coaxially mounted on the shaft portion 35 and fitted in an externally fitted state. And a movable part 12 mounted rotatably. A through hole 35a serving as a fixed side hole is formed in the shaft portion 35 so that the height position is the same as that of the through hole 14a and the hole direction is orthogonal to the axis. The shaft portion 35 is formed with a flange portion that prevents the movable portion 12 from coming off.

このように構成された第２プーリ１０Ａでは、図示していないが、例えば実施の形態１における固定ピン１６を貫通穴３５ａ，１４ａに挿通状態に装着することで、可動部１２が軸部３５、即ちプーリ取付台６に固定される。また、固定ピン１６を貫通穴３５ａ，１４ａから取り外すことで、可動部１２と軸部３５との拘束状態が解除され、可動部１２が軸部３５、即ちプーリ取付台６に対して回転自在となる。
従って、この実施の形態５による第２プーリ１０Ａを第２プーリ１０に代えて動力伝達機構を構成しても、同様の効果が得られる。 In the second pulley 10A configured in this manner, although not shown, for example, by attaching the fixing pin 16 in the first embodiment to the through holes 35a and 14a so as to be inserted, the movable portion 12 becomes the shaft portion 35, That is, it is fixed to the pulley mounting base 6. Further, by removing the fixing pin 16 from the through holes 35a and 14a, the restrained state between the movable portion 12 and the shaft portion 35 is released, and the movable portion 12 is rotatable with respect to the shaft portion 35, that is, the pulley mounting base 6. Become.
Therefore, even if the second pulley 10A according to the fifth embodiment is replaced with the second pulley 10 to configure a power transmission mechanism, the same effect can be obtained.

FIG. 14 is a cross-sectional view illustrating the configuration of the second pulley in the power transmission mechanism of the developed structure according to Embodiment 6 of the present invention.
In FIG. 14, the second pulley 10 B includes a cylindrical shaft portion 36 as a fixed portion formed integrally with the pulley mounting base 6, and a shaft portion 36 that is coaxially mounted on the shaft portion 36 and fitted in an internally fitted state. And a fixed bolt 37 loosely inserted in the axial center position of the movable portion 12 and fastened to the shaft portion 36. A pair of through holes 36a as fixed side holes are formed in the shaft portion 36 so that the hole direction is orthogonal to the axis. Further, a pair of holes 14b as movable side holes are recessed in the cylindrical portion 14 so that the height position is the same as the through hole 36a and the hole direction is orthogonal to the axis.

このように構成された第２プーリ１０Ｂでは、図示していないが、例えば実施の形態３におけるピン部２６を貫通穴３６ａおよび穴１４ｂに差し込んで装着することで、可動部１２が軸部３６、即ちプーリ取付台６に固定される。また、ピン部２６を貫通穴１４ａから取り外すことで、可動部１２と軸部３６との拘束状態が解除され、可動部１２が軸部３６、即ちプーリ取付台６に対して回転自在となる。
従って、この実施の形態６による第２プーリ１０Ｂを第２プーリ１０に代えて動力伝達機構を構成しても、同様の効果が得られる。 In the second pulley 10B configured in this manner, although not shown, for example, by inserting the pin portion 26 in the third embodiment into the through hole 36a and the hole 14b and mounting, the movable portion 12 becomes the shaft portion 36, That is, it is fixed to the pulley mounting base 6. Further, by removing the pin portion 26 from the through hole 14a, the restrained state of the movable portion 12 and the shaft portion 36 is released, and the movable portion 12 is rotatable with respect to the shaft portion 36, that is, the pulley mounting base 6.
Therefore, even if the second pulley 10B according to the sixth embodiment is replaced with the second pulley 10 to configure a power transmission mechanism, the same effect can be obtained.

図１５はこの発明の実施の形態７に係る展開構造物の動力伝達機構における第２プーリの構成を説明する断面図である。
図１５において、第２プーリ１０Ｃは、プーリ取付台６に締着固定される固定部としての円柱状の軸部３５と、軸部３５に同軸、かつ、外嵌状態に装着されて軸部３５に回転自在に取りつけられた可動部１２と、を備えている。この軸部３５には、可動部１２の抜けを防止するフランジ部が形成されている。そして、固定側穴としての一対の貫通穴３５ｂが穴方向を軸心に平行として、軸心を中心として対称な位置に軸部３５のフランジ部に穿設されている。また、可動側穴としての一対の穴１４ｃが穴方向を軸心に平行として、各貫通穴３５ｂに対応するように可動部１２に形成されている。 Embodiment 7 FIG.
FIG. 15 is a cross-sectional view illustrating the configuration of the second pulley in the power transmission mechanism of the developed structure according to Embodiment 7 of the present invention.
In FIG. 15, the second pulley 10 C includes a columnar shaft portion 35 as a fixing portion that is fastened and fixed to the pulley mounting base 6, and a shaft portion 35 that is coaxially mounted on the shaft portion 35 and fitted in an externally fitted state. And a movable part 12 mounted rotatably. The shaft portion 35 is formed with a flange portion that prevents the movable portion 12 from coming off. A pair of through holes 35b as fixed side holes are formed in the flange portion of the shaft portion 35 at positions symmetrical with respect to the shaft center with the hole direction parallel to the shaft center. Further, a pair of holes 14c as movable side holes are formed in the movable portion 12 so as to correspond to the respective through holes 35b with the hole direction being parallel to the axial center.

このように構成された第２プーリ１０Ｃでは、図示していないが、例えば実施の形態１における固定ピン１６を貫通穴３５ｂおよび穴１４ｃに差し込んで装着することで、可動部１２が軸部３５、即ちプーリ取付台６に固定される。また、固定ピン１６を貫通穴３５ｂおよび穴１４ｃから取り外すことで、可動部１２と軸部３５との拘束状態が解除され、可動部１２が軸部３５、即ちプーリ取付台６に対して回転自在となる。
従って、この実施の形態７による第２プーリ１０Ｃを第２プーリ１０に代えて動力伝達機構を構成しても、同様の効果が得られる。 In the second pulley 10 C configured as described above, although not shown, for example, by inserting the fixing pin 16 in the first embodiment into the through hole 35 b and the hole 14 c and mounting, the movable portion 12 becomes the shaft portion 35, That is, it is fixed to the pulley mounting base 6. Further, by removing the fixing pin 16 from the through hole 35b and the hole 14c, the restrained state of the movable portion 12 and the shaft portion 35 is released, and the movable portion 12 is rotatable with respect to the shaft portion 35, that is, the pulley mounting base 6. It becomes.
Therefore, even when the second pulley 10C according to the seventh embodiment is replaced with the second pulley 10, a power transmission mechanism is configured, and the same effect can be obtained.

Further, the nine panels 3 are in a two-dimensionally expanded state as shown in FIG.

つぎに、動力伝達機構について、図１８を参照しつつ説明する。なお。図１８は本体部２側から５番目乃至８番目のパネル３の群を示している。
一対のプーリ取付台６が、本体部２側から１番目、３番目、５番目および７番目の各パネル３のヒンジ結合された２つの側面のヒンジ４，５の回転軸心の方向の一側縁部にそれぞれ一体に配設されている。また、プーリ取付台６が、本体部２側から９番目のパネルのヒンジ結合された側面のヒンジ５の回転軸心の方向の一側縁部に一体に配設されている。
そして、一対のプーリ取付台６が、本体部２側から２番目、４番目、６番目および８番目の各パネル３のヒンジ結合された２つの側面のヒンジ４，５の回転軸心の方向の他側縁部にそれぞれ一体に配設されている。また、プーリ取付台６が、本体部２のヒンジ結合された側面のヒンジ４の回転軸心の方向の他側に一体に配設されている。
そして、本体部２側から１番目乃至８番目の各パネル３に取り付けられた一対のプーリ取付台６には、それぞれ第１プーリ７および第２プーリ１０が取り付けられている。また、本体部２および９番目のパネル３に取り付けられた各プーリ取付台６には、それぞれ第１プーリ７および第２プーリ１０が取り付けられている。
そして、本体部２側から奇数番目のパネル群において、隣り合うパネル３同士が、同期ワイヤ１８を一方のパネル３に取り付けられた第１プーリ７と他方のパネル３に取り付けられた第２プーリ１０とに緊張状態で掛け渡されて、連結されている。同様に、本体部２と本体部２側から偶数番目のパネル群において、隣り合うパネル３同士が、同期ワイヤ１８を一方のパネル３に取り付けられた第１プーリ７と他方のパネル３に取り付けられた第２プーリ１０とに緊張状態で掛け渡されて、連結されている。ここでは、説明の便宜上、本体部２もパネル３として表現している。 Next, the power transmission mechanism will be described with reference to FIG. Note that. FIG. 18 shows a group of the fifth to eighth panels 3 from the main body 2 side.
A pair of pulley mounting bases 6 are located on one side in the direction of the rotational axis of the hinges 4 and 5 on the two side surfaces of the first, third, fifth and seventh panels 3 that are hinged to the main body 2 side. Each of the edges is integrally provided. Further, the pulley mounting base 6 is integrally disposed on one side edge portion in the direction of the rotation axis of the hinge 5 on the side surface of the ninth panel hinged to the ninth panel from the body portion 2 side.
Then, the pair of pulley mounting bases 6 are arranged in the direction of the rotation axis of the hinges 4 and 5 on the two side surfaces of the second, fourth, sixth and eighth panels 3 which are hinged from the main body 2 side. The other side edge portions are integrally disposed. The pulley mounting base 6 is integrally disposed on the other side in the direction of the rotation axis of the hinge 4 on the side surface of the main body 2 to which the hinge is coupled.
A first pulley 7 and a second pulley 10 are attached to a pair of pulley mounting bases 6 attached to the first to eighth panels 3 from the main body 2 side, respectively. A first pulley 7 and a second pulley 10 are respectively attached to the pulley mounting bases 6 attached to the main body 2 and the ninth panel 3.
Then, in the odd-numbered panel group from the main body 2 side, adjacent panels 3 are connected to each other by the first pulley 7 having the synchronization wire 18 attached to one panel 3 and the second pulley 10 attached to the other panel 3. It is stretched over and connected to each other. Similarly, in the even-numbered panel group from the main body 2 and the main body 2 side, adjacent panels 3 are attached to the first pulley 7 attached to one panel 3 and the other panel 3 with the synchronization wire 18 attached. The second pulley 10 is connected in a tensioned state. Here, for convenience of explanation, the main body 2 is also expressed as a panel 3.

ここで、展開方向を変えるパネル３間の連結方法について説明する。
同期ワイヤ１８は、６番目のパネル３に取り付けられたステー４０に設けられた溝に通されて張力方向を９０度変換されて、５番目のパネル３に取り付けられた第１プーリ７と７番目のパネル３に取り付けられた第２プーリ１０とに緊張状態で掛け渡される。これにより、７番目のパネル３は、５番目のパネル３に対する６番目のパネル３の展開方向と直交する方向に展開される。
また、同期ワイヤ１８は、７番目のパネル３に取り付けられたステー４１に設けられた溝に通されて張力方向を９０度変換されて、６番目のパネル３に取り付けられた第１プーリ７と８番目のパネル３に取り付けられた第２プーリ１０とに緊張状態で掛け渡される。これにより、８番目のパネル３は、６番目のパネル３に対する７番目のパネル３の展開方向と直交する方向に展開される。
なお、３番目、４番目および５番目のパネル３も、同様に連結されている。 Here, the connection method between the panels 3 which change a developing direction is demonstrated.
The synchronizing wire 18 is passed through a groove provided in a stay 40 attached to the sixth panel 3, the tension direction is changed by 90 degrees, and the first pulley 7 attached to the fifth panel 3 and the seventh pulley are attached. It is stretched over the second pulley 10 attached to the panel 3 in a tensioned state. As a result, the seventh panel 3 is expanded in a direction orthogonal to the expansion direction of the sixth panel 3 relative to the fifth panel 3.
Further, the synchronization wire 18 is passed through a groove provided in a stay 41 attached to the seventh panel 3, the tension direction is changed by 90 degrees, and the first pulley 7 attached to the sixth panel 3 is connected to the first pulley 7. It is stretched around the second pulley 10 attached to the eighth panel 3 in a tension state. As a result, the eighth panel 3 is expanded in a direction orthogonal to the expansion direction of the seventh panel 3 relative to the sixth panel 3.
The third, fourth, and fifth panels 3 are similarly connected.

このように、この実施の形態８においても、第２プーリ１０の胴部１１と可動部１２に対する固定ピン１６の抜き差しにより、パネル３の対の同期／非同期状態（拘束状態／非拘束状態）が切り換えられるので、上記実施の形態１と同様の効果が得られる。 Thus, also in this eighth embodiment, the pair 3 of the panel 3 is synchronized / asynchronized (restrained / unconstrained) by inserting / removing the fixed pin 16 with respect to the body 11 and the movable portion 12 of the second pulley 10. Since they are switched, the same effect as in the first embodiment can be obtained.

なお、上記各実施の形態では、各パネル３に第１および第２プーリ７，１０を取り付けるものとして説明しているが、第１プーリ７に代えて第２プーリ１０を用い、各パネル３に第２プーリ１０，１０を取り付けるようにしてもよい。
また、上記各実施の形態では、太陽電池パネルが山折りと谷折りを交互に繰り返すように収納された展開構造物について説明しているが、パネルは太陽電池パネルに限定されるものではなく、パネルが山折りと谷折りを交互に繰り返すように収納される展開構造物であればよく、フェーズドアンテナ、大型アンテナ、太陽光集光板等のパネルを用いてもよい。
また、上記各実施の形態では、宇宙船に収納状態で搭載され、軌道上にて展開する展開構造物について説明しているが、この発明は、この形態に限定されるものではなく、パネルが山折りと谷折りを交互に繰り返すように収納される展開構造物に適用できることは言うまでもないことである。 In each of the above embodiments, the first and second pulleys 7 and 10 are described as being attached to each panel 3, but the second pulley 10 is used instead of the first pulley 7, and each panel 3 is attached to each panel 3. The second pulleys 10 and 10 may be attached.
Further, in each of the above embodiments, the solar cell panel is described as an unfolded structure stored so as to alternately repeat the mountain fold and the valley fold, but the panel is not limited to the solar cell panel, The panel may be a developed structure that is housed so as to alternately repeat mountain folds and valley folds, and a panel such as a phased antenna, a large antenna, or a solar light collector may be used.
In each of the above embodiments, a deployment structure that is mounted in a spacecraft and deployed in orbit is described. However, the present invention is not limited to this embodiment, and a panel is provided. It goes without saying that the present invention can be applied to an unfolded structure that is housed so that mountain folds and valley folds are alternately repeated.
