Description
本考案は、自動二輪車等に取り付けられたキャブレターのアイドリング調整をするためのアイドリング調整工具及びそれを備えたキャブレターに関する。 The present invention relates to an idling adjustment tool for adjusting the idling of a carburetor attached to a motorcycle or the like, and a carburetor equipped with the same.
自動二輪車等に取り付けられるキャブレターは、空気と燃料を混合した混合気の供給量を制御する装置であり、キャブレターには様々なタイプのものがある。それらを用いるエンジンを搭載した機械の中で、年式やその特性によっては極めて頻繁にアイドリング調整作業を必要とするものが存在する。特に、キャブレターの形状や構造、調整機構の位置や角度、並びにキャブレターを取り付けたエンジンの形状、構造によってはドライバーなどの工具を必要とする物がある。従来、キャブレターのアイドリング調整作業を行うツールとして各種提案がなされている。（特許文献１，２参照） A carburetor attached to a motorcycle or the like is a device that controls the supply amount of a mixture of air and fuel, and there are various types of carburetors. Among machines equipped with engines that use these, there are machines that require idling adjustment work extremely frequently depending on the model year and its characteristics. In particular, tools such as screwdrivers may be required depending on the shape and structure of the carburetor, the position and angle of the adjustment mechanism, and the shape and structure of the engine to which the carburetor is attached. Conventionally, various proposals have been made as tools for adjusting the idling of a carburetor. (See Patent Documents 1 and 2)
ここで、自動二輪車用の米国リンカート社製キャブレターを例に挙げる。当該キャブレターのアイドリング調整は、運転者が走行中であっても常時携帯していたドライバー（工具）を用いて頻繁に行われていた。ところが、このキャブレターのアイドリング調整部（雄ねじ）が奥まった狭い場所にあるため、エンジンの振動に伴って揺動するアイドリング調整部をドライバーにて回転させる動作は非常に困難であり、走行中に工具を落下させる危険性もあった。 Here, we will take as an example a carburetor manufactured by Linkert, Inc. in the US for motorcycles. The idling adjustment of the carburetor was frequently performed using a screwdriver (tool) that the driver carried with him at all times even while driving. However, since the idling adjustment part (male thread) of this carburetor is located in a recessed and narrow place, it is extremely difficult to use a screwdriver to rotate the idling adjustment part, which swings with the vibrations of the engine. There was also the risk of it falling.
また、特許文献２の遠隔調整装置はアイドリング調整部とケーブルが直接繋がっている構造であるため、ケーブル部分を曲率が大きい曲線でしか曲げることができず、上記米国リンカート社製キャブレターの様なアイドリング調整部が奥まった場所にある場合、遠隔調整装置の装着自体が非常に困難であった。さらに、このようなアイドリング調整部に、遠隔調整装置のケーブル部を大きな曲線となるように曲げて強引に装着すると、遠隔調整装置のノブ部分が他部品に干渉してしまい、雄ねじを回転させる動作が非常に困難であった。加えて、このような取り付け方で使用を続けた場合、アイドリング調整部やワイヤーの接続部分などに負荷がかかり、遠隔調整装置の破壊やキャブレター本体の破壊を招いていた。 In addition, since the remote adjustment device of Patent Document 2 has a structure in which the idling adjustment part and the cable are directly connected, the cable part can only be bent in a curve with a large curvature. If the idle adjustment section is located in a deep place, it is very difficult to attach the remote adjustment device. Furthermore, if the cable part of the remote adjustment device is bent into a large curve and forcefully attached to such an idling adjustment part, the knob part of the remote adjustment device will interfere with other parts, and the operation of rotating the male screw will be interrupted. was extremely difficult. In addition, if the engine was installed in this way, continued use would place stress on the idling adjustment section, wire connections, etc., leading to damage to the remote adjustment device and the carburetor itself.
本考案は上記問題点に鑑みてなされたものであり、あらゆるタイプのキャブレターに対応でき、アイドリング調整工具の可動範囲が大きく自在性に優れており、キャブレターのアイドリング調整時にキャブレターの調整機構や調整工具への過負荷を軽減し、円滑に調整操作を行うことができるアイドリング調整工具及びそれを備えたキャブレターを提供することを目的とする。 The present invention was developed in view of the above problems, and is compatible with all types of carburetors.The idling adjustment tool has a large movable range and is highly flexible.

（アイドリング調整工具の構成）
図１に示すように、本形態のアイドリング調整工具１０は、自動二輪車等のキャブレターのアイドリング調整部に取り付けられて、アイドリング調整を行うための工具であり、スクリュー部材１と、長尺状の軸部材２と、スクリュー部材１と軸部材２とを連結する自由関節３とを備えている。(Configuration of idling adjustment tool)
As shown in FIG. 1, the idling adjustment tool 10 of this embodiment is a tool that is attached to the idling adjustment part of a carburetor of a motorcycle or the like to adjust the idling, and includes a screw member 1 and a long shaft. It includes a member 2 and a free joint 3 that connects the screw member 1 and the shaft member 2.
スクリュー部材１はステンレスや鉄などの金属素材からなり、一端側（図示左側）に後述するキャブレター調整部に適合するサイズのねじ切り加工を施した雄ねじ４と、他端側に内径が１～５ｍｍ程度の第１の透孔ｈ１が穿設された頭部５を一体的に有している。なお、キャブレター調整部は、キャブレターのスロットルバルブの開き具合を調整する部位であり、右回りに締めればアイドリング回転数が上昇し、左回りに緩めればアイドリング回転数は下降する。 The screw member 1 is made of a metal material such as stainless steel or iron, and has a male thread 4 on one end (on the left side in the figure) that is threaded to a size suitable for the carburetor adjustment part described later, and the other end has an internal diameter of about 1 to 5 mm. The head 5 is integrally formed with a first through hole h1. The carburetor adjustment part is a part that adjusts the opening degree of the throttle valve of the carburetor. Tightening it clockwise will increase the idling speed, and loosening it counterclockwise will decrease the idling speed.
長尺状の軸部材２は、一端側（図示右側）に使用者が指先でつまむことができるつまみ部６と、他端側に内径が１～５ｍｍ程度の第２の透孔ｈ２が穿設された接続部８と、つまみ部６と接続部８を繋ぐ本体部７とを有している。つまみ部６の外周には滑り止め用のローレット加工が施されている。本体部７は、硬鋼線材やステンレス鋼線材などからなるワイヤーや、ステンレス等の棒材や、金属と樹脂の複合材等の素材で構成され、直径が２～１０ｍｍ程度、長さが５０～２００ｍｍ程度の長尺部材である。本体部７の両端はつまみ部６および接続部８に固着されている。具体的には、つまみ部６の端部に本体部７を挿嵌可能な有底穴６ａが形成されると共に、接続部８の端部に本体部７を挿嵌可能な有底穴８ａが形成され、それぞれの有底穴６ａ、８ａに本体部７の端部を挿嵌してカシメや溶接等で固着されている。なお、当該アイドリング調整工具１０の操作性を高める観点から、本体部７をワイヤー等で構成し、本体部７に可撓性を持たせることが望ましい。 The elongated shaft member 2 has a knob portion 6 on one end (on the right side in the figure) that the user can pinch with his or her fingertips, and a second through hole h2 with an inner diameter of about 1 to 5 mm on the other end. The main body part 7 connects the knob part 6 and the connection part 8. The outer periphery of the knob portion 6 is knurled to prevent slipping. The main body 7 is made of a material such as a wire made of hard steel wire or stainless steel wire, a bar made of stainless steel, or a composite material of metal and resin, and has a diameter of about 2 to 10 mm and a length of about 50 to 50 mm. It is a long member of about 200 mm. Both ends of the main body part 7 are fixed to the knob part 6 and the connecting part 8. Specifically, a bottomed hole 6a into which the main body 7 can be inserted is formed at the end of the knob 6, and a bottomed hole 8a into which the main body 7 can be inserted is formed at the end of the connecting portion 8. The end portions of the main body portion 7 are inserted into the respective bottomed holes 6a and 8a and fixed by caulking, welding, or the like. In addition, from the viewpoint of improving the operability of the idling adjustment tool 10, it is preferable that the main body part 7 is made of wire or the like to give the main body part 7 flexibility.
図２に示すように、自由関節３は、スクリュー部材１の頭部５に穿設された第１の透孔ｈ１と、軸部材２の接続部８に穿設された第２の透孔２ｈを連通する環状体９を有する。本実施形態において、環状体９はステンレスや鉄等の素材からなる丸カンもしくは二重カンである。環状体９の外形は円形に限らず、楕円形、丸みを帯びた矩形、多角形などを採用することができる。環状体９を構成する素材の太さは、第１および第２の透孔ｈ１、ｈ２の内径よりも細い。当該アイドリング調整工具１０を回転操作する際、環状体９に一定の負荷がかかるため、環状体９はその負荷に耐えうる強度・耐久性を有するものとする。 As shown in FIG. 2, the free joint 3 includes a first through hole h1 drilled in the head 5 of the screw member 1, and a second through hole 2h drilled in the connecting portion 8 of the shaft member 2. It has an annular body 9 that communicates with the. In this embodiment, the annular body 9 is a round ring or double ring made of a material such as stainless steel or iron. The outer shape of the annular body 9 is not limited to a circle, but may be an ellipse, a rounded rectangle, a polygon, or the like. The thickness of the material constituting the annular body 9 is thinner than the inner diameters of the first and second through holes h1 and h2. When the idling adjustment tool 10 is rotated, a certain load is applied to the annular body 9, so the annular body 9 should have strength and durability to withstand the load.
スクリュー部材１と軸部材２は環状体９を有する自由関節３により連結されている。それ故、図３に示すように、自由関節３を基点として、スクリュー部材１と軸部材２は相対的に任意の方向に角度を変化させることができる。換言すれば、スクリュー部材１をキャブレターのアイドリング調整部に取り付けて固定した場合、自由関節３の存在によって、軸部材２はスクリュー部材１に対して任意の方向に回動可能である。例えば、軸部材２を矢印Ｂや矢印Ｃの方向に回動させたり、紙面手前側や紙面奥側に回動させたりすることができる。
なお、自由関節３は、本実施形態のように２つの透孔ｈ１、ｈ２に連通する環状体９で構成する形態のほか、周知のユニバーサルジョイントや自在継手でスクリュー部材１と軸部材２を連結してもよい。 The screw member 1 and the shaft member 2 are connected by a free joint 3 having an annular body 9. Therefore, as shown in FIG. 3, the angle of the screw member 1 and shaft member 2 can be relatively changed in any direction with the free joint 3 as a base point. In other words, when the screw member 1 is attached and fixed to the idling adjustment part of the carburetor, the shaft member 2 can rotate in any direction with respect to the screw member 1 due to the presence of the free joint 3. For example, the shaft member 2 can be rotated in the direction of arrow B or arrow C, or can be rotated toward the front or back of the page.
The free joint 3 may be constructed of an annular body 9 that communicates with the two through holes h1 and h2 as in this embodiment, or may be constructed by connecting the screw member 1 and the shaft member 2 with a well-known universal joint or universal joint. You may.
そして、図３に示すように、軸部材２の一端側のつまみ部６を指でつまんで、例えば右回りに所定の回転角だけ回すと、その回転力が自由関節３を介してスクリュー部材１に伝わり、スクリュー部材１が同等の回転角で右回りに締められる。したがって、キャブレターの調整部が奥まった場所にあっても、つまみ部６の位置を他部品に干渉しない位置まで延出することができるので、アイドリング調整操作を容易に行うことができる。 As shown in FIG. 3, when the knob 6 on one end of the shaft member 2 is pinched with fingers and turned clockwise, for example, by a predetermined rotation angle, the rotational force is transferred to the screw member 1 through the free joint 3. , and the screw member 1 is tightened clockwise at the same rotation angle. Therefore, even if the adjusting section of the carburetor is located in a deep place, the position of the knob section 6 can be extended to a position where it does not interfere with other parts, so that the idling adjustment operation can be easily performed.
図４に示すように、アイドリング調整工具１０は、軸部材２のつまみ部６の近傍からスクリュー部材１の頭部５にかけて、樹脂製またはゴム製のカバー部材Ｃで封止することが望ましい。カバー部材Ｃとしては、耐熱編組チューブや収縮チューブを単独または併用で用いることができる。キャブレターの周囲は、エンジンが駆動すると比較的高温になるうえ、風雨や紫外線に晒されるため、カバー部材Ｃでアイドリング調整工具１０の大部分を被覆することで、機能を低下させずに保護することができ、耐久性が向上する。 As shown in FIG. 4, the idling adjustment tool 10 is preferably sealed with a cover member C made of resin or rubber from the vicinity of the knob 6 of the shaft member 2 to the head 5 of the screw member 1. As the cover member C, a heat-resistant braided tube or a shrinkable tube can be used alone or in combination. The area around the carburetor becomes relatively hot when the engine is running and is exposed to wind, rain and ultraviolet rays, so by covering most of the idling adjustment tool 10 with the cover member C, it is possible to protect it without reducing its functionality. and improves durability.
以上のように、本考案にかかるアイドリング調整工具１０は、スクリュー部材１と軸部材２が自由関節３を介して連結され、スクリュー部材１に対して軸部材２が任意の方向に回動可能であるため、アイドリング調整を行う際にキャブレターの調整機構や調整工具にかかっていた負荷が軽減されて、両者が破損・変形することを未然に抑止することができる。さらに、キャブレターの調整部が奥まった場所にあっても、調整用のつまみ部６の位置を他部品に干渉しない位置まで延出することができるので、アイドリング調整操作を容易に行うことができる。さらにまた、このアイドリング調整工具１０をキャブレターに常時取り付けておけば、キャブレター調整用のドライバーを携帯する必要もなくなるため工具の落下の危険性も生じない。 As described above, in the idling adjustment tool 10 according to the present invention, the screw member 1 and the shaft member 2 are connected via the free joint 3, and the shaft member 2 is rotatable in any direction with respect to the screw member 1. Therefore, the load placed on the carburetor adjustment mechanism and adjustment tool when adjusting the idling is reduced, and damage and deformation of both can be prevented. Furthermore, even if the adjustment part of the carburetor is located in a deep place, the position of the adjustment knob part 6 can be extended to a position where it does not interfere with other parts, so that the idling adjustment operation can be easily performed. Furthermore, if this idling adjustment tool 10 is always attached to the carburetor, there is no need to carry a screwdriver for adjusting the carburetor, and there is no risk of the tool falling.
（アイドリング調整工具を備えたキャブレターの構成）
図５に示すキャブレター２０は、最もベーシックな米国リンカート社製キャブレターであって、固定ベンチュリ―式＋強制開閉というキャブレターの原理原則的な仕組みを採用している。ロースピードニードル２１とハイスピードニードル２２で混合気の調整を行うことができる。エンジン稼動時四面手前側から空気を吸い込み筒状の本体を抜けていく際に矢印２０あたりでガソリンと空気が混ざり混合気となりエンジン内部に吸い込まれる。その際に本体内部（２３あたり）についている開閉扉がアクセルと連結しておりアクセルの開け閉めによりエンジン内部におくりこむ混合気の量を調整する。停車時アイドリングを調整する際は２３に接続されている部品１０の６（つまみ）を持ち回転させることで調整が可能となる。(Carburetor configuration with idling adjustment tool)
The carburetor 20 shown in FIG. 5 is the most basic carburetor made by Linkert, Inc. in the United States, and employs the basic mechanism of a carburetor: fixed venturi type + forced opening/closing. The mixture can be adjusted using the low speed needle 21 and the high speed needle 22. When the engine is running, air is sucked in from the front side on all sides and as it passes through the cylindrical body, gasoline and air mix at around arrow 20 to form a mixture and are sucked into the engine. At that time, an opening/closing door attached to the inside of the main body (around 23) is connected to the accelerator, and the amount of air-fuel mixture sent into the engine is adjusted by opening and closing the accelerator. When adjusting the idling when the vehicle is stopped, the adjustment can be made by holding the knob 6 (knob) of the part 10 connected to 23 and rotating it.
符号２３は、左右に回転させてアイドリングの回転数を設定するアイドリング調整部として機能するスロットルストップスクリューが本来取り付けられていた位置である。本実施形態において、図５に示すように、このスロットルストップスクリュー２３（アイドリング調整部）の位置に、上述した実施形態にかかるアイドリング調整工具１０が取り付けられている。すなわち、キャブレター２０に元々螺合されていたスロットルストップスクリュー２３に替えて、アイドリング調整工具１０のスクリュー部材１の雄ねじ４が螺合されている。なお、雄ねじ４のピッチや直径・寸法はスロットルストップスクリュー２３と同一に加工されている。そして、つまみ部６はアイドリング調整部２２から所定距離以上離れた開放空間に位置している。所定距離とは、アイドリング調整工具１０の全長と同等の長さであり、例えば１００～２５０ｍｍとすることができる。 The reference numeral 23 is the position where the throttle stop screw, which functions as an idling adjustment section that rotates left and right to set the idling speed, was originally installed. In this embodiment, as shown in FIG. 5, the idling adjustment tool 10 according to the embodiment described above is attached to the position of the throttle stop screw 23 (idling adjustment section). That is, instead of the throttle stop screw 23 that was originally screwed onto the carburetor 20, the male thread 4 of the screw member 1 of the idling adjustment tool 10 is screwed onto it. Note that the pitch, diameter, and dimensions of the male thread 4 are machined to be the same as those of the throttle stop screw 23. The knob portion 6 is located in an open space at least a predetermined distance away from the idling adjustment portion 22. The predetermined distance is a length equivalent to the entire length of the idling adjustment tool 10, and can be, for example, 100 to 250 mm.
本考案にかかるアイドリング調整工具１０が長尺である上、自由関節３がスクリュー部材１に対して軸部材２を任意の方向に回動可能に連結していて、しかも、自由関節３が局部的に屈曲できるため、作業者は奥まった場所にあるアイドリング調整部にわざわざ工具を当てることなく、軸部材２の一端側にあるつまみ部６を左右に回すだけで、容易にアイドリング調整を行うことができる。 The idling adjustment tool 10 according to the present invention is long, and the free joint 3 connects the shaft member 2 to the screw member 1 so as to be rotatable in any direction. Since the shaft member 2 can be bent to the left or right, the operator can easily adjust the idling by simply turning the knob 6 at one end of the shaft member 2 to the left or right, without having to touch the idling adjustment part located in a deep place with a tool. can.
