Description
【考案の詳細な説明】
この−’ｌは、ゴムボートの船底より水中に突出させて
ボートの保針性風上航性能を向上させるセンターボード
の昇降装置に関するものである。[Detailed Description of the Invention] This item -'1 relates to a centerboard lifting device that protrudes into the water from the bottom of a rubber boat to improve the course-keeping and windward sailing performance of the boat.
従来、ゴムボートには簡単な構造で且つ廉価に製造でき
るセンターボード昇降装置が存在せず、従ってゴムボー
トに帆を立てて風を受けて走行するセールボートとして
使用することができなかった。Conventionally, rubber boats have not had centerboard lifting devices that have a simple structure and can be manufactured at low cost, and therefore, rubber boats cannot be used as sailboats that travel in the wind by setting up sails on them.
この考案は上述の難点を解消し、ボート内部に水が侵入
せず簡単な構造で且つ廉価に製造できるセンターボード
昇降装置を提供することを目的とするものである。The object of this invention is to solve the above-mentioned difficulties and to provide a centerboard lifting device that does not allow water to enter the boat, has a simple structure, and can be manufactured at low cost.
以下、この考案の構成を一実施例として示した図面に従
って説明する。Hereinafter, the configuration of this invention will be explained with reference to the drawings shown as one embodiment.
ゴムボートの船首中心点と船尾中心点を結ぶ線上で船底
１に適宜長さの切り目を形成し、この切り目に透孔な有
する枠箱３の先端部を挿脱自在に嵌装し、枠箱３の外周
を巻回するように船底１内面に空気室２を固着形成して
いる。A cut of an appropriate length is formed in the bottom 1 on a line connecting the center point of the bow and the center point of the stern of the rubber boat, and the tip of the frame box 3 having a through hole is removably inserted into the cut. An air chamber 2 is fixedly formed on the inner surface of the boat bottom 1 so as to wrap around the outer circumference of the boat.
空気室２は空気を充填することによって空気室２の外壁
で枠箱３を押圧して支持するのであるが、同時に船底１
に形成した切り目から侵入した水がボート内部にまで達
するのを防ぐ役目も果たすのである。By filling the air chamber 2 with air, the outer wall of the air chamber 2 presses and supports the frame box 3, but at the same time, the bottom of the ship 1
It also serves to prevent water from entering through the cuts made in the boat from reaching the inside of the boat.
すなわち、空気室２の船底１からの高さはゴムボートの
吃水線よりも高く形成しているので、空気室２と枠箱３
の間を通って侵入した水は空気室２を越えてボート内部
には入って来ない。In other words, since the height of the air chamber 2 from the bottom 1 of the boat is higher than the water line of the rubber boat, the height of the air chamber 2 and the frame box 3 is higher than the water line of the rubber boat.
Water that has entered through the space does not cross the air chamber 2 and enter the inside of the boat.
また、枠箱３の透孔にはセンターボード４を摺動自在に
挿通しており、先端部はボートの船底１より水中に突出
させて自由に昇降することができる。Further, a center board 4 is slidably inserted into the through hole of the frame box 3, and the tip thereof projects into the water from the bottom 1 of the boat so that it can be freely raised and lowered.
枠箱３の高さは空気室２の船底１からの高さよりも高く
形成しているので、水は枠箱３を越えてボート内部に入
って来ることはない。Since the height of the frame box 3 is formed higher than the height of the air chamber 2 from the bottom 1 of the boat, water does not cross the frame box 3 and enter the inside of the boat.
さらに、この枠箱３とセンターボード４は取外し可能で
あるから、センターボード４を使用して走行中に不要に
なれば取外してそのまま通常のゴムボートとして使用す
ることができ大変便利であると共に、持運びも容易であ
る。Furthermore, since the frame box 3 and centerboard 4 are removable, if the centerboard 4 is no longer needed while the boat is running, it can be removed and used as a normal rubber boat, which is very convenient and portable. It is also easy to transport.
この考案は上述のような構成を有するもので、ボート内
部には水が侵入することはく、簡単な構造で且つ廉価に
製造できるセンターボード昇降装置を提供するものであ
り、実用的効果に優れている。This invention has the above-mentioned structure, and provides a centerboard lifting device that prevents water from entering the boat, has a simple structure, can be manufactured at low cost, and has excellent practical effects. ing.
