本発明は、置型の断面を有する硬１肌と、この硬帆の後
端部に展帆される軟帆とから成る複合帆の改良に関し、
特に硬帆の折り曲げ構造を提供するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the improvement of a composite sail consisting of a hard sail having a stationary cross section and a soft sail that is extended at the rear end of the hard sail.
In particular, it provides a folding structure for rigid sails.
大型の船舶の運航に要するエネルギーを節約するために
、船舶に帆装置を植立して風力を有効に利用する方法が
提案されている。In order to save the energy required for operating large ships, a method has been proposed in which a sail device is installed on the ship to effectively utilize wind power.
この種の帆装置として、最も有効な構造の物としては置
型の断面を有する硬帆と、この硬帆の後輪部に展帆され
る軟帆との組合せからなる複合帆がある。The most effective structure of this type of sail device is a composite sail consisting of a hard sail with a stationary cross section and a soft sail that is extended from the rear wheel of the hard sail.
この複合帆は、船舶に比例してかなり大型のもあが採用
されており、例えば硬帆の高さが２０〜６０ｍで幅か２
〜６ｍのものが実用化されようとしている。This composite sail uses a sail that is quite large in proportion to the ship, for example, the height of the hard sail is 20 to 60 m and the width is about 2.
~6m length is about to be put into practical use.
前記のように複合帆はかなり大型の装置であり、従来の
帆装置を有しない船舶に比較して高い構造物を植立して
いる関係上、港湾設備や橋等にも影響される場合が多い
。従って若し硬帆が港１４設備や橋に比較して高いもの
である場合にはごの硬帆が邪魔になって、入・出港及び
橋の通過が困難となる。As mentioned above, composite sails are quite large devices, and because they have tall structures erected compared to ships without conventional sail devices, they may be affected by port facilities, bridges, etc. many. Therefore, if the hard sail is higher than the port equipment or bridge, the hard sail will get in the way, making it difficult to enter and leave the port and pass through the bridge.
また、航海中に台風のような強風を船舶が受ける場合に
はこの複合帆がそのま＼の状態に植立していることば危
険な場合かある。Furthermore, if a ship is exposed to strong winds such as a typhoon while sailing, it may be dangerous to leave the composite sail in place.
前記のように大型の硬帆がその高さのま＼で植立してい
ると各種の問題を生ずるので、ごの問題点を解消するこ
とが必要となる。As mentioned above, if large hard sails are planted at that height, various problems will occur, so it is necessary to solve these problems.

The upper rigid sail 6 has a support member 1 at its tip that supports it.
5 is provided. This supporting member may be oar-shaped as in the embodiment, or an existing device on the deck of the ship may be used, or a device for fixing the upper hardness: 1σt6 to this supporting gH material 15 may be provided. good.
第２図より明らかなように、上部硬帆６の一側面の中央
部が端部より削られて溝部８が形成されている。従って
、上部硬帆６の溝部８を設けた部分の断面ば、「コ」字
状となっている。As is clear from FIG. 2, the center portion of one side of the upper hard sail 6 is cut away from the end portion to form a groove portion 8. Therefore, the cross section of the portion of the upper hard sail 6 in which the groove portion 8 is provided has a "U" shape.
また、この溝部８の深さは、上部硬ＩＪ・Ｌ６の端部が
最も深く、先端に向か鵜に従って次第に浅（形成されて
いる。Further, the depth of this groove portion 8 is the deepest at the end of the upper hard IJ/L6, and gradually becomes shallower toward the tip.
また、断面の「コ」字形状は出口側が広く、奥になるに
従って狭くなっており、上部硬帆６を植立するとぎ延長
部７を溝部８に収納できるようになっている。Further, the U-shaped cross section is wide on the exit side and narrows toward the back, so that the extension part 7 can be stored in the groove part 8 when the upper hard sail 6 is erected.
本考案において、溝部８を上部硬帆６の片面に形成し、
この溝部８の内部に下部硬帆５の延長部７を収容するよ
うに構成し、この延長部７の先端部にヒンジ１０を設け
、この延長部７の先端部で上部硬帆６の中央部を支持す
るように構成した点に特徴がある。In the present invention, the groove 8 is formed on one side of the upper hard sail 6,
The extension part 7 of the lower hard sail 5 is housed inside the groove part 8, and a hinge 10 is provided at the tip of the extension part 7, and the tip of the extension part 7 connects the center part of the upper hard sail 6. It is distinctive in that it is configured to support.
このように硬帆４を構成することによって、上部硬帆６
は片面に溝部８が形成されているが他の面には切り込み
が無く、第１図の植立状態においては下部硬帆５と上部
硬帆６との組合せによって断面が置型の硬帆４を構成し
ている。By configuring the hard sail 4 in this way, the upper hard sail 6
has a groove 8 formed on one side, but no notch on the other side, and in the planted state shown in Fig. 1, the combination of the lower hard sail 5 and the upper hard sail 6 creates a hard sail 4 with a stationary cross section. It consists of
結局、上部硬帆６は最小限の範囲内で溝部８が形成され
ていること−なり、上部硬帆６に対して強度的に不利な
点を避けている。As a result, the upper rigid sail 6 has the groove portion 8 formed within the minimum range, thereby avoiding disadvantages in terms of strength compared to the upper rigid sail 6.
また、上部硬帆６のヒンジ１０を設ける部分に重心が来
るように構成することによって、バランス性が向上し、
必要な駆動力が小さくなり上部硬帆６を植立・倒伏が容
易となるのである。In addition, by configuring the upper rigid sail 6 so that the center of gravity is located at the part where the hinge 10 is provided, balance is improved,
The required driving force is reduced, and the upper rigid sail 6 can be easily planted and lowered.
本考案に係る複合帆によれば、大型の複合帆であっても
これを簡単に植立し、また倒伏することが可能であり、
大型の船舶用の複合帆に効果的に採用することが可能で
ある。According to the composite sail according to the present invention, even a large composite sail can be easily set up and lowered,
It can be effectively employed in composite sails for large ships.
