Description

【０００１】
【発明の属する技術分野】
この発明は、自動車のオイルパンの内部のオイル（潤滑油）の量を検出するためのオイルレベルゲージに関するものである。
【０００２】
【従来の技術】
従来のオイルレベルゲージは、丸棒状で、一端部に平板状のゲージ部が設けられるとともに、他端部にピン挿入孔が設けられた杆体と、この杆体の他端部側を挿入する円筒状の挿入穴が設けられるとともに、ピン挿入孔に連通する外側ピン挿入孔が設けられた取手部と、挿入穴へ杆体の他端部側を挿入した状態で連通する外側ピン挿入孔およびピン挿入孔へ挿入することにより、取手部に対して杆体を固定するピンとで構成されている。
【０００３】
次に、このオイルレベルゲージの組立について説明する。
まず、取手部に設けられた円筒状の挿入穴へ丸棒状の杆体の他端部側を挿入しながら外側ピン挿入孔とピン挿入孔とを連通させる。
そして、連通した外側ピン挿入孔およびピン挿入孔へピンを挿入し、取手部に対して杆体を固定することにより、組立が完了する。
【０００４】
【発明が解決しようとする課題】
上述したように、オイルレベルゲージを組み立てる場合、挿入穴へ杆体の他端部側を挿入しながら外側ピン挿入孔とピン挿入孔とを連通させなければならないが、挿入穴が円筒状で、杆体が丸棒状であるので、外側ピン挿入孔とピン挿入孔とを連通させる位置決めがし難く、組立を作業性よく行うことができなかった。
また、取付平板部をプレス加工によって形成するため、取付平板部の挿入穴に対する寸法精度は悪いものである。
したがって、取付平板部のみで杆体を取手部に取り付けると、取付平板部と挿入穴との隙間により、取手部に対する杆体のがたつきが大きくなってしまう。
【０００５】
この発明は、上記したような不都合を解消するためになされたもので、組立を作業性よく行うことができ、杆体を取手部へがたつかないように取り付けることのできるオイルレベルゲージを提供するものである。
【０００６】
【課題を解決するための手段】
この発明にかかるオイルレベルゲージは、丸棒状で、一端部に平板状のゲージ部が設けられるとともに、他端部にピン挿入孔を有する取付平板部、および、この取付平板部のゲージ部と反対側に連なる丸棒部分が設けられた杆体と、取付平板部の少なくとも一部を収容する挿入穴の奥に、丸棒部分が挿入される円筒状の嵌合穴が設けられるとともに、ピン挿入孔に連通する外側ピン挿入孔が設けられた取手部と、挿入穴および嵌合穴へ杆体の他端部側を挿入した状態で連通する外側ピン挿入孔およびピン挿入孔へ挿入することにより、取手部に対して杆体を固定するスプリングピンとからなり、挿入穴は、丸棒部分が挿通される、嵌合穴に連通した丸孔部分と、この丸孔部分の両側へ突出し、取付平板部の両側端部が挿入される扁平な回動規制部分とからなることを特徴とする。
【０００７】
【発明の実施の形態】
以下、この発明の実施形態を図面に基づいて説明する。
図１はこの発明の一実施形態であるオイルレベルゲージの一部を省略した分解斜視図、図２は図１に示した杆体、取手部およびスプリングピンを組み立てて一部を破断した要部の正面図、図３は図２に示したオイルレベルゲージ部分の縦断面図である。
【０００８】
これらの図において、Ｇはオイルレベルゲージを示し、杆体１１と、この杆体１１が取り付けられる取手部２１と、この取手部２１に対して杆体１１を抜けないように固定するスプリングピン３１と、取手部２１にシール性を確保するために取り付けられるＯリング４１，４２とで構成されている。
【０００９】
上記した杆体１１は、丸棒状をした金属製で、一端部にプレス加工で形成した平板状のゲージ部１２が設けられ、他端部にピン挿入孔１４を有するプレス加工で形成した取付平板部１３が設けられるとともに、取付平板部１３の他端側（ゲージ部１２と反対側）に丸棒部分１５が連接させて設けられている。
そして、ゲージ部１２には、一端側（取付平板部１３から遠い方）に下限標線１２ｄが刻設され、他端側（取付平板部１３に近い方）に上限標線１２ｕが刻設されている。
なお、ピン挿入孔１４は、取付平板部１３の平面に垂直に設けられている。
【００１０】
上記した取手部２１は、合成樹脂製で、下端の外周が下側へ窄む円錐面２２ｃとされた円柱部２２と、この円柱部２２の上端に円柱部２２よりも太径で、円柱部２２と同軸に連設された鍔部２８と、この鍔部２８の上端に同軸に連設され、指を通すことのできる環状部分を有した取手部分２９とで構成されている。
そして、円柱部２２には、下端に開放し、取付平板部１３が挿入される挿入孔（穴）２３と、この挿入孔２３と同軸で、挿入孔２３の奥に連設された丸棒部分１５が嵌合する円筒状の嵌合穴２４と、取付平板部１３を挿入孔２３へ挿入した状態でピン挿入孔１４に連通する外側ピン挿入孔２５と、この外側ピン挿入孔２５よりも上側外周にＯリング４１，４２を収容する周回したＯリング収容溝２６，２７とが設けられている。
上記した挿入孔２３は、丸棒部分１５が挿通される円筒状の丸孔部分２３ｃの両側に扁平な四角が均等に突出した平断面形で、丸孔部分２３ｃから突出した部分が回動規制部分２３ｆとなっている。
【００１１】
Ｐはオイルパンを示し、杆体１１が挿入され、円柱部２２および鍔部２８で閉塞され、周壁にＯリング４１，４２が密接する挿通孔ｈを有する装着部Ｍが設けられている。
【００１２】
次に、オイルレベルゲージＧの組立について説明する。
まず、取手部２１のＯリング収容溝２６，２７にＯリング４１，４２を収容させた後、挿入孔２３の丸孔部分２３ｃに杆体１１の丸棒部分１５を対応させるとともに、回動規制部分２３ｆに取付平板部１３の両端を対応させ、丸棒部分１５側を挿入孔２３内へ挿入させる。
このように丸棒部分１５側を挿入孔２３内へ挿入させると、図２および図３に示すように、丸棒部分１５は丸孔部分２３ｃで案内されて嵌合穴２４に嵌合し、取付平板部１３の両端は回動規制部分２３ｆに嵌合し、外側ピン挿入孔２５とピン挿入孔１４とは連通する。
【００１３】
この連通した状態の外側ピン挿入孔２５およびピン挿入孔１４へスプリングピン３１を挿入する（圧入させる）ことにより、スプリングピン３１によって取手部２１に対して杆体１１を抜けないように固定することができ、オイルレベルゲージＧの組立が完了する。
【００１４】
次に、オイルレベルゲージＧの使用方法について説明する。
上述のようにして組み立てたオイルレベルゲージＧのゲージ部１２側を下にし、杆体１１をゲージ部１２側から装着部Ｍの挿通孔ｈ内へ挿入すると、円錐面２２ｃがガイド面となって円柱部２２を挿通孔ｈ内へ案内する。
そして、図２に示すように、鍔部２８が装着部Ｍへ当接する状態まで取手部２１を押し込むと、円柱部２２が挿通孔ｈに嵌合し、Ｏリング４１，４２が挿通孔ｈの周壁に密接するとともに、鍔部２８が装着部Ｍの上端に当接することにより、挿通孔ｈは閉塞される。
【００１５】
そして、取手部分２９の環状部分に指を挿通して引っ掛け、引っ張ると、円柱部２２が挿通孔ｈから外れるので、そのままオイルレベルゲージＧを装着部Ｍから引き抜けば、オイルがゲージ部１２のどの部分まで付着しているか、付着したオイルの色により、オイルパンＰ内に適量のオイルが入っているか、オイルが汚れていないかなどを知ることができる。
【００１６】
上述したように、この発明の一実施形態によれば、杆体１１にピン挿入孔１４を有する取付平板部１３を設け、取手部２１に取付平板部１３を収容して杆体１１の回動を阻止する扁平な回動規制部分２３ｆを有する挿入孔２３を設けるとともに、ピン挿入孔１４に連通する外側ピン挿入孔２５を設けたので、取付平板部１３を単に挿入孔２３へ挿入するだけで外側ピン挿入孔２５とピン挿入孔１４とを連通させることができる。
したがって、オイルレベルゲージＧを作業性よく組み立てることができる。
【００１７】
そして、杆体１１の取付平板部１３のゲージ部１２と反対側に連接させて丸棒部分１５を設け、取手部２１の挿入孔２３に連接させて丸棒部分１５が嵌合する嵌合穴２４を設けたので、丸棒部分１５が嵌合穴２４に嵌合することにより、取手部２１に対して杆体１１をがたつかないように取り付けることができる。
また、取付部２１を構成する円柱部２２の下端の外周を下側へ窄む円錐面２２ｃとしたので、円錐面２２ｃがガイド面となり、取手部２１（円柱部２２）を装着部Ｍの挿通孔ｈへスムーズに挿入することができる。
【００１８】
【発明の効果】
以上説明したように、この発明によれば、杆体にピン挿入孔を有する取付平板部を設け、取手部に取付平板部を収容して杆体の回動を阻止する扁平な回動規制部分を有する挿入穴を設けるとともに、ピン挿入孔に連通する外側ピン挿入孔を設けたので、取付平板部を単に挿入穴へ挿入するだけで外側ピン挿入孔とピン挿入孔とを連通させることができる。
したがって、オイルレベルゲージを作業性よく組み立てることができる。
そして、杆体の取付平板部のゲージ部と反対側に連接させて丸棒部分を設け、取手部の挿入穴に連接させて丸棒部分が嵌合する嵌合穴を設けたので、丸棒部分が嵌合穴に嵌合することにより、取手部に対して杆体をがたつかないように取り付けることができる。

The above-described housing 11 is made of a metal having a round bar shape, and is provided with a flat gauge portion 12 formed by pressing at one end and a mounting flat plate formed by pressing having a pin insertion hole 14 at the other end. 13 is provided, and a round bar portion 15 is connected to the other end side (opposite side of the gauge portion 12) of the mounting flat plate portion 13.
The gauge part 12 is engraved with a lower limit mark 12d on one end side (away from the mounting plate part 13) and an upper limit mark 12u on the other end side (closer to the attachment plate part 13). ing.
The pin insertion hole 14 is provided perpendicular to the plane of the mounting flat plate portion 13.
[0010]
The handle part 21 described above is made of a synthetic resin and has a cylindrical part 22 having a conical surface 22c whose outer periphery at the lower end is constricted downward, and has a diameter larger than that of the cylindrical part 22 at the upper end of the cylindrical part 22. 22 is constituted by a collar portion 28 that is coaxially connected to 22 and a handle portion 29 that is coaxially connected to the upper end of the flange portion 28 and has an annular portion through which a finger can pass.
The cylindrical portion 22 is open to the lower end and is inserted into an insertion hole (hole) 23 into which the mounting flat plate portion 13 is inserted, and a round bar portion that is coaxial with the insertion hole 23 and is continuously provided behind the insertion hole 23. 15, a cylindrical fitting hole 24 that fits in, an outer pin insertion hole 25 that communicates with the pin insertion hole 14 in a state in which the mounting flat plate portion 13 is inserted into the insertion hole 23, and an upper side than the outer pin insertion hole 25. Circulated O-ring receiving grooves 26 and 27 for storing O-rings 41 and 42 are provided on the outer periphery.
Insertion holes 23 described above is a plan cross-sectional shape round bar portion 15 has both sides in a flat square equally protruding cylindrical round hole portion 23c to be inserted, turning the protruding portion from the circular hole portion 23 c It is a restriction portion 23f.
[0011]
P denotes an oil pan, and the housing 11 is inserted, is closed by the cylindrical portion 22 and the collar portion 28, and is provided with a mounting portion M having an insertion hole h in which the O-rings 41 and 42 are in close contact with the peripheral wall.
[0012]
Next, assembly of the oil level gauge G will be described.
First, after the O-rings 41 and 42 are accommodated in the O-ring accommodating grooves 26 and 27 of the handle portion 21, the round bar portion 15 of the housing 11 is made to correspond to the round hole portion 23c of the insertion hole 23, and the rotation restriction is performed. Both ends of the mounting flat plate portion 13 are made to correspond to the portion 23 f and the round bar portion 15 side is inserted into the insertion hole 23.
Thus, when the round bar portion 15 side is inserted into the insertion hole 23, the round bar portion 15 is guided by the round hole portion 23c and fitted into the fitting hole 24, as shown in FIGS. Both ends of the mounting flat plate portion 13 are fitted into the rotation restricting portion 23f, and the outer pin insertion hole 25 and the pin insertion hole 14 communicate with each other.
