【考案の詳細な説明】
この考案は、船外機等のエンジンのスロワ１〜ル弁開度
規制装置に関する。[Detailed Description of the Invention] This invention relates to a throttle valve opening regulating device for an engine such as an outboard motor.
船外機は、上部のエンジンで下部のスクリューを駆動し
ており、その間に前進用ギヤと後進用ギヤがあり、変速
レバーに連動する噛合クラッチで、前進、中立、後進が
選択できるようになっている。An outboard motor uses an engine at the top to drive a screw at the bottom, and between them there is a forward gear and a reverse gear, and a dog clutch linked to the gear shift lever allows you to select forward, neutral, or reverse. ing.
そして、エンジンが高回転のとき、噛合クラッチを入れ
たりすると、ギヤか次けたり、船が急に暴走したりする
危険か′ある。Also, if you engage the dog clutch when the engine is running at high speeds, there is a danger that the gear may shift or the boat may suddenly go out of control.
この考案は、かかる点に鑑み、変速レバーが中立時は、
スロットル弁が一定以上開かないようにして、エンジン
か゛高回転にならないようにして、上記のようなことが
起きないようにしたもので、以下図面に示す本考案の実
施例について説明する。In consideration of this point, this invention has been developed so that when the gear shift lever is in neutral,
The throttle valve is prevented from opening beyond a certain level, and the engine is prevented from reaching a high speed, thereby preventing the above-mentioned situation from occurring.An embodiment of the present invention shown in the drawings will be described below.
変速レバー１は中立Ｎ位置から、Ｆ ｆｕｌｌに傾ける
と前進位置になり、Ｒ側に傾けると後進位置になる。When the shift lever 1 is tilted from the neutral N position to F full, it becomes a forward position, and when it is tilted to the R side, it becomes a reverse position.
そして、変速レバー１にリンク２を介して、揺動片３を
連動させる。Then, the swinging piece 3 is interlocked with the speed change lever 1 via the link 2.
揺動片３は、気化器ボテ゛−４に回動自在に軸着しであ
る。The swinging piece 3 is rotatably attached to the carburetor body 4.
一方、エンジンの回転をコントロールするスロットル弁
５の軸６の一側に規制板７を固着する。On the other hand, a regulating plate 7 is fixed to one side of a shaft 6 of a throttle valve 5 that controls the rotation of the engine.
規制板７は一側に切欠き８を設け、他側は、アクセルレ
バ−に連動するボーデンワイヤ９に連結してあって、ス
ロットル弁５の操作アームを兼ねている。The regulating plate 7 has a cutout 8 on one side, and the other side is connected to a Bowden wire 9 that is linked to an accelerator lever, and also serves as an operating arm for the throttle valve 5.
そして、揺動片３に設けた突部１０が、規制板７の切欠
き８に近接するようにしである。The protrusion 10 provided on the swinging piece 3 is arranged to be close to the notch 8 of the regulating plate 7.
作用について説明する。The effect will be explained.
変速レバー１が中立位置のとき、揺動片３の突部１０が
、規制板７の切欠き８に近接している。When the shift lever 1 is in the neutral position, the protrusion 10 of the swing piece 3 is close to the notch 8 of the regulation plate 7.
従ってホ゛−テ゛ンワイヤ９を引いて、スロットル弁５
を開こうとしても、切欠き８が、すぐ突部１０に当り、
それ以上は開くことができなくなる。Therefore, pull the main wire 9 and close the throttle valve 5.
Even if you try to open it, the notch 8 will immediately hit the protrusion 10,
It will not be possible to open it any further.
こうして、エンジン回転を上昇させなくできる。In this way, it is possible to prevent the engine rotation from increasing.
変速レバー１を前進又は後進位置にすると、これに連動
して揺動片３が揺動し、突部１０が切欠き８から離れる
。When the shift lever 1 is placed in the forward or reverse position, the swing piece 3 swings in conjunction with this, and the protrusion 10 separates from the notch 8.
従って、規制板７は、自由に回動できるようになり、ス
ロットル弁５を大きく開いて、エンジンを高回転にでき
る。Therefore, the regulation plate 7 can freely rotate, the throttle valve 5 can be opened wide, and the engine can be rotated at high speed.
以上説明したように、この考案は、変速レバーに連動す
る揺動片を設け、スロットル弁の一側に一端に切欠きを
設けた規制板を設け、変速レバーが中立時に揺動片の突
部が規制板の切欠きに近接し、変速レバーが、前進又は
後進位置のとき、揺動片の突部が規制板から離れるよう
にしたので、中立時にスロットル弁を開こうとしても規
制板の切欠きが、揺動片の突部に当って、それ以上開か
ないので、エンジン回転を高くすることがない。As explained above, this invention provides a rocking piece that interlocks with the gear shift lever, and a regulating plate with a notch at one end on one side of the throttle valve. When the gear lever is in the forward or reverse position, the protrusion of the rocking piece moves away from the restriction plate, so even if you try to open the throttle valve in neutral, the restriction plate will not cut out. Since the notch hits the protrusion of the rocking piece and does not open any further, the engine speed does not increase.
こうして、エンジンの空吹かしを規制でき、急激に噛合
ドッグを噛合せることもなくなって、破損が防止できる
。In this way, it is possible to restrict the engine from revving, prevent the meshing dogs from engaging suddenly, and prevent damage.
又、構造も簡単で、安価にでき、安全性が向上する。In addition, the structure is simple and inexpensive, and safety is improved.
図は本考案の一実施例を示す正面図である。 The figure is a front view showing an embodiment of the present invention.
