〈技術分野〉
本発明はボードセーリング、更に詳しくはセイ
リング中にマストからブームが絶対に離れないボ
ードセーリングに関する。DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to board sailing, and more particularly to board sailing in which the boom never separates from the mast during sailing.
〈従来技術〉
従来、ウインドサーフイン（登録商標）用ブー

締結する方法が一般に行なわれている。<Prior art> Conventionally, in order to attach a windsurf-in (registered trademark) boom to a mast, as shown in Fig. 1, the mast is tied to the inside of the boom using a rope or the like. .

た。 However, with this method of attachment, when forces are applied to the sail during sailing, the boom is forced away from the mast, causing the fasteners to loosen. If this fastening part becomes loose, it is not only difficult to operate, but also extremely dangerous. Therefore, although great care has been taken in this fastening, no matter how much care is taken, it has not been possible to completely prevent loosening.

造について検討を進め、本発明に到達したのであ
る。 As a result of extensive research into a fastening method that would ensure that the mast and boom never separate during sailing, the inventor of the present invention decided to completely reverse the conventional method of combining the mast and boom, that is, combining the mast with the boom on the outside of the boom. I came to the conclusion that if the boom were pressed against the mast when a force was applied to the sail, the fastening would not loosen at all during sailing, even if I did not have to be very careful about the fastening. After studying the structure, they arrived at the present invention.

グに係るものである。<Structure of the Invention> That is, the present invention is used in board sailing, in which a recess is provided in the front part of a boom used to fit the mast, the mast is fitted into the recess, the mast is combined, and a presser piece is applied from the outside of the boom. This relates to board sailing in which the boom and mast are integrated by fixing the boom and mast.
本発明を図面によつて説明する。第１図は従来
のブームを示した図である。１はブーム、２はマ
ストの断面である。従来の方法では、ブーム１の
フロント部の内側にマスト２を合体させており、
この場合、セールに力が働くと、ブームは左方向
に移動するような力が働く、即ちマストから離れ
ようとする力が働き締結部が緩み易い。 The present invention will be explained with reference to the drawings. FIG. 1 is a diagram showing a conventional boom. 1 is the boom, and 2 is the cross section of the mast. In the conventional method, the mast 2 is integrated inside the front part of the boom 1,
In this case, when a force is applied to the sail, a force is applied that moves the boom to the left, that is, a force that tends to move the boom away from the mast, making the fastening part likely to loosen.
第２図は、本発明のブームの基本を示す図であ
り、ブーム１のフロント部にマスト２に合致した
凹部を設けてある。このようにすることにより、
セールに力が働くと、ブームは左方向に移動する
ような力が働く、即ちマストにより密着しようと
する力が働き、締結部が緩むことはない。 FIG. 2 is a diagram showing the basics of the boom of the present invention, in which a recessed portion that matches the mast 2 is provided in the front portion of the boom 1. By doing this,
When a force is applied to the sail, a force is applied to the boom to move it to the left, that is, a force is applied to the boom to make it fit closer to the mast, so that the fastening part does not come loose.
第３図は、本発明の実施態様例を示す図であ
り、マストにブームを合体させた後、押え片３を
外側から当てがつた場合を示している。 FIG. 3 is a diagram showing an embodiment of the present invention, and shows a case where the presser piece 3 is applied from the outside after the boom is combined with the mast.
第４図は、第３図と異なる本発明の実施態様例
であり、押え片３としてグリツプを設けたものを
使用したものである。 FIG. 4 shows an embodiment of the present invention different from that shown in FIG. 3, in which a grip is provided as the presser piece 3.
第３図及び第４図における押え片の材質は、強
靭で、錆びにくいものが好ましく、例えばステン
レス板、強化プラスチツク板等は特に好ましいも

定することができる。 The material of the holding piece shown in FIGS. 3 and 4 is preferably strong and rust-resistant, and for example, stainless steel plate, reinforced plastic plate, etc. are particularly preferable. Moreover, the means for fixing the presser piece to the boom may be arbitrary, and can be easily fixed using a belt or the like, for example.
ブーム自体の材質は、強靭で、軽く、錆びない
ものが使用され、従来使用されているものも、任
意に使用できる。 The material used for the boom itself is strong, light, and rust-free, and conventional materials can be used as desired.
なお、本発明のブームを使用するに当たつて、

ーム接触部における衝撃力を緩和するために、こ
の接触部にプレートや弾性板等を当てがうことも
好ましいことである。 In addition, when using the boom of the present invention,
It is also preferable to apply a plate, an elastic plate, etc. to the contact area of the mast in order to reduce the impact force generated at the boom contact area of the mast when a force is applied to the sail.
