本考案は、ボルトの螺軸部に嵌装された座金と弾性シール体とによりボルトを 締め付けた際にボルトの頭部と締結部材との間を密閉することができるボルトの シール装置に関するものである。 The present invention relates to a bolt seal device that can seal between a bolt head and a fastening member when a bolt is tightened by a washer fitted to a screw shaft portion of the bolt and an elastic seal body. is there.
【0002】[0002]
この種のボルトのシール装置は、水の浸入等に対する確実な密閉効果があるう えに取付作業が容易である必要があるのでこれらの観点から種々の改良が試みら れており、その1例として最近では実開平5ー58933号に示される技術があ る。この技術は図3および図4に示すように、ボルトBの螺軸部に嵌装される皿 型の座金Wとゴムなどの弾性材よりなる凸環状のパッキンPとよりなり、ボルト Bの回動により被締結部材Jに締結部材Kが締結されるようにしたもので、詳し くは、パッキンPに座金Wの内周面とボルトBの外周面との間に嵌まる環状突起 Paを形成する一方、座金Wの内周縁WaをボルトBの先端方向に向けてくの字 状に折り曲げることによりパッキンPの一端面Pbと座金Wとの間に隙間Sを形 成してある。 This type of bolt sealing device needs to be easy to install in order to have a reliable sealing effect against water intrusion, and various improvements have been tried from these viewpoints. Recently, there is the technology shown in Jitsukaihei 5-58933. As shown in FIGS. 3 and 4, this technique comprises a dish-shaped washer W fitted on the screw shaft portion of the bolt B and a convex annular packing P made of an elastic material such as rubber. The fastening member K is fastened to the fastened member J by the movement. Specifically, the packing P has an annular projection Pa fitted between the inner peripheral surface of the washer W and the outer peripheral surface of the bolt B. On the other hand, the inner peripheral edge Wa of the washer W is bent in a dogleg shape toward the tip of the bolt B to form a gap S between the one end face Pb of the packing P and the washer W.
【0003】 このようなボルトのシール装置は、まず、ボルトBに座金Wを嵌めてから、座 金Wの内周の孔部に凸環状のパッキンPの環状突起Paを嵌める作業が必要であ り、この後、ボルトBを被締結部材Jのめねじ部に締結部材Kを挟んでねじ込み 図3で示されるようにパッキンPの一端面Pbと座金W間に隙間Sが生じている 状態とし、この状態により、ボルトBを回動して被締結部材Jにねじ込むと、座 金Wの内周縁Waが矢印方向、即ち、パッキンPの内周部に食い込む。その後、 パッキンPは座金Wの押圧作用により大きく変形し、遂には図4で示されるよう に、パッキンPは座金Wと締結部材Kとの間およびボルトBの環状凹所Ba内に 充満されて締結作業を完了する。この状態において、パッキンPは座金Wのスカ ート部Wb、鍔部Wcに拘束されて外部に露出されることなく外観上の見栄えは 良好となる。In such a bolt sealing device, it is necessary to first fit the washer W to the bolt B and then to fit the annular projection Pa of the convex annular packing P into the hole on the inner circumference of the washer W. After that, the bolt B is screwed into the female thread portion of the member J to be fastened with the fastening member K sandwiched therebetween, and as shown in FIG. 3, a gap S is formed between the one end face Pb of the packing P and the washer W. In this state, when the bolt B is rotated and screwed into the fastened member J, the inner peripheral edge Wa of the washer W bites in the arrow direction, that is, the inner peripheral portion of the packing P. After that, the packing P is largely deformed by the pressing action of the washer W, and finally, as shown in FIG. 4, the packing P is filled between the washer W and the fastening member K and in the annular recess Ba of the bolt B. Complete the fastening work. In this state, the packing P is not restricted by the skirt portion Wb and the collar portion Wc of the washer W and is not exposed to the outside, and the appearance is good.
【0004】 ところが、このようなボルトのシール装置では上記したボルトの締め付けの際 に隙間SによってパッキンPの一端面Pbに対する押圧力は緩和されるものの、 特に矢印に示す座金Wの内周縁Waによる力によってパッキンPが大きく変位さ れ締め付け力も大きくなる傾向があり、締め付け、取り外しを何回も繰り返すと きは、パッキンPを傷めて復元性を無くする要因となるという問題が残されてい た。However, in such a bolt seal device, although the pressing force against the one end face Pb of the packing P is relaxed by the gap S when the bolt is tightened as described above, the inner peripheral edge Wa of the washer W shown by an arrow in particular is reduced. The packing P tends to be largely displaced by the force and the tightening force also tends to be large, and if tightening and removing are repeated many times, the problem remains that the packing P is damaged and the restorability is lost.

本考案が解決しようとするところは、前記した従来のボルトのシール装置の長 所を残したまま問題点のみを改良し、座金とパッキンとを一体化することにより 構成部品を少なくして作業の容易性を高めるとともに、締め付け、取り外しを何 回も繰り返してもシール性が損なわれることがなく、しかも、軽いボルトの締め 付け力により確実に密閉可能としたボルトのシール装置を提供することにある。 The problem to be solved by the present invention is to improve only the problem while maintaining the advantages of the conventional bolt seal device described above, and to reduce the number of components by integrating the washer and the packing. (EN) Provided is a bolt sealing device which not only enhances the easiness, but also does not impair the sealing performance even if it is repeatedly tightened and removed, and which is capable of reliably sealing with a light bolt tightening force. .

前記のような課題を解決した本考案に係るボルトのシール装置は、ボルトの螺 軸部にシール部材を嵌装したボルトのシール装置において、前記シール部材は環 状の座金と環状の弾性シール体とが一体化されたものとし、且つ、前記座金は、 内側を傾斜内庇とした環状座板部の外周縁に短筒状の裾部を連設してその内部を 弾性シール体収納部に形成したものであり、一方、前記弾性シール体は、前記座 金のシール体収納部に収納一体化された環状盤部の中央に中間部分が前記傾斜内 庇に対応する狭窄部に形成された短筒部を連設してその遊端に前記環状座板部よ り突出する環状***部を形成するとともに環状盤部の座面に前記裾部の端縁より 突出する複数の環状リップを形成したものであることを特徴とするものである。 The bolt sealing device according to the present invention, which has solved the above-mentioned problems, is a bolt sealing device in which a sealing member is fitted on a screw shaft portion of the bolt, wherein the sealing member is an annular washer and an annular elastic sealing body. And the washer are integrated, and the washer has a short tubular hem part continuously connected to the outer peripheral edge of the annular seat plate part having an inclined inner side, and the inside thereof serves as an elastic seal body storage part. On the other hand, in the elastic seal body, an intermediate portion is formed in a narrowed portion corresponding to the inclined inner portion at the center of the annular plate portion housed integrally in the seal body housing portion of the washer. A series of short cylinders are formed to form an annular ridge projecting from the annular seat plate at its free end, and a plurality of annular lips projecting from the edge of the skirt on the seating surface of the annular disc. It is characterized by being

このような本考案に係るボルトのシール装置は、取付シール作業に際しては座 金と弾性シール体とが一体化されたシール部材が螺軸部に嵌められているボルト を被締付部材と締付部材の孔に通して裏側のナットに螺合し回動するだけでよい ので取付作業性が極めてよいうえに、シール部分は弾性シール体に形成されて座 金より突出している環状突縁と環状リップとが有効に平面状に変形して行われる こととなるので、軽くボルトを締め付けるだけで密閉は確実なものとなり、しか も、座金はその外周縁に短筒状の裾部があるのでその縦幅に制限されて過度の締 め付けは防止される。 In the bolt sealing device according to the present invention, a seal member, in which a washer and an elastic seal body are integrated, is attached to a screw shaft portion when a mounting seal work is performed. It only needs to be screwed through the hole of the member and screwed into the nut on the back side to rotate, so the mounting workability is very good, and the sealing part is formed on the elastic seal body and has an annular ridge protruding from the washer and an annular shape. Since the lip is effectively deformed into a flat surface, a light bolt can be tightened to ensure a tight seal, but the washer has a short tubular hem on its outer peripheral edge. Restricted to the vertical width, excessive tightening is prevented.

The annular disc portion 36 is housed and integrated in the seal body accommodating portion 28 and the short tubular portion 34 is The outer peripheral portion is integrated with the diameter-increasing slope 23 and the diameter-decreasing slope 24 of the sloped inner visor 26.
【0011】 そして、このシール部材5をボルト1の螺軸部2に前記座金21を平面座4側 として嵌装しただけの締め付け以前においては、環状座板部22より上方に突出 する弾性シール体31の上面の環状***部33が平面座4に接するだけで座金2 1の環状座板部22は平面座4に接することがなく、また、シール部材5をボル ト1の螺軸部2に嵌め込んだ状態でボルト1の螺軸部2を締結部材51とこれに 重ねられる被締結部材52の各孔部に通しただけの状態ではシール部材5の弾性 シール体31の下面に形成されている環状リップ35のみが締結部材51に接し ているが座金21の短筒状の裾部27の端縁は締結部材51に接することがなく また、弾性シール体31の短筒部34の中間の狭窄部32は螺軸部2に接した図 1に示す状態となり、更に、弾性シール体31の短筒部34の中間の狭窄部32 は螺軸部2に接していて螺軸部2の上端と頭部3の平面座4と弾性シール体31 の短筒部34の拡径斜面23との間に断面3角状の環状空間41が形成されると ともに、螺軸部2の上方部分と締結部材51と弾性シール体31の短筒部34と の間にも断面3角状の環状空間42が生じるように設定されている。Before tightening the seal member 5 by simply fitting the washer 21 on the screw shaft portion 2 of the bolt 1 with the flat seat 4 side, an elastic seal body protruding upward from the annular seat plate portion 22. Only the annular raised portion 33 on the upper surface of 31 is in contact with the flat seat 4, the annular seat plate portion 22 of the washer 21 is not in contact with the flat seat 4, and the seal member 5 is attached to the screw shaft portion 2 of the bolt 1. When the threaded shaft portion 2 of the bolt 1 is simply inserted into the holes of the fastening member 51 and the fastened member 52 to be overlapped therewith, it is formed on the lower surface of the elastic seal body 31 of the seal member 5. Only the annular lip 35 that is in contact with the fastening member 51, but the edge of the short tubular skirt portion 27 of the washer 21 does not contact the fastening member 51. The narrowed portion 32 is in contact with the screw shaft portion 2 as shown in FIG. In addition, the narrowed portion 32 in the middle of the short tubular portion 34 of the elastic seal body 31 is in contact with the screw shaft portion 2, and the upper end of the screw shaft portion 2, the flat seat 4 of the head 3 and the elastic seal body 31. An annular space 41 having a triangular cross section is formed between the short cylindrical portion 34 and the enlarged diameter slope 23, and the upper cylindrical portion 34 of the screw shaft portion 2, the fastening member 51, and the elastic seal body 31 is formed. Also, an annular space 42 having a triangular cross section is formed between and.
【0012】 このように構成されたボルトのシール装置は、シール部材5として環状の弾性 シール体31と環状の座金21とが一体化されたものを用いているので、取付シ ール作業に際してはこのシール部材5のみをボルト1の螺軸部2に嵌めるだけで 後は螺軸部2を締結部材51とこれに重ねられる被締結部材52の各孔部に通し て溶接ナット53に螺合すればよく、取付け作業が極めて簡略化できる。In the bolt seal device having the above-described structure, the seal member 5 has the annular elastic seal body 31 and the annular washer 21 integrated with each other. Only the seal member 5 is fitted to the screw shaft portion 2 of the bolt 1, and then the screw shaft portion 2 is passed through the holes of the fastening member 51 and the member 52 to be fastened to be overlapped therewith, and screwed into the welding nut 53. The installation work can be greatly simplified.
【0013】 しかも、このシール部材5の弾性シール体31は中間を狭窄部32とした短筒 部34の遊端に環状座板部22より突出する環状***部33を形成するとともに 基端には座金21の裾部27の端縁より突出する複数の環状リップ35が座面に 形成された環状盤部36を連設したものであるから、締め付け時には図2に示す ように環状***部33が圧潰された状態で短筒部34の遊端がボルト1の頭部2 の下面の平面座4に密接されるとともに、複数の環状リップ35が圧潰された状 態で環状盤部36の座面が締付部材51に密接されるとともに、環状空間41、 42は共に埋められた状態となり、この弾性シール体31の変形による弾性力に より優れたシール効果を発揮することとなり、断面波状の環状リップ35の波数 を増加すれば更にシール効果を高めることができ、また、環状***部33と環状 リップ35は従来の弾性シール体に比べてはるかに軽い締付力で的確に変形しシ ール効果を発揮する。さらに、座金21の裾部27の端縁が締付部材51を撓み なく押圧するので、適切な軸力と締付力を保持することができる。しかも、この 弾性シール体31は環状座板部22の外周縁に裾部27を連設して内部に形成し た弾性シール体収納部28内に一体に設けられているので、過度な締付力が弾性 シール体31に加えられることがなく締め付け過ぎは完全に防止される。Moreover, the elastic seal body 31 of the seal member 5 has an annular raised portion 33 protruding from the annular seat plate portion 22 at the free end of the short cylindrical portion 34 having the narrowed portion 32 at the middle thereof, and at the base end thereof. Since a plurality of annular lips 35 projecting from the edge of the hem portion 27 of the washer 21 are connected to the annular disc portion 36 formed on the seating surface, the annular ridge 33 is tightened as shown in FIG. 2 during tightening. In the crushed state, the free end of the short tubular portion 34 is brought into close contact with the flat seat 4 on the lower surface of the head portion 2 of the bolt 1, and the seating surface of the annular disc portion 36 is crushed in a state where the annular lips 35 are crushed. Is closely contacted with the tightening member 51, and the annular spaces 41 and 42 are both filled, so that the elastic force due to the deformation of the elastic seal body 31 exerts a superior sealing effect. The wave number of lip 35 If the number is increased, the sealing effect can be further enhanced, and the annular ridge 33 and the annular lip 35 can be accurately deformed with a much lighter tightening force as compared with the conventional elastic seal body to exert the sealing effect. Further, since the end edge of the skirt portion 27 of the washer 21 presses the tightening member 51 without bending, it is possible to maintain appropriate axial force and tightening force. Moreover, since the elastic seal body 31 is integrally provided in the elastic seal body accommodating portion 28 formed inside by forming the skirt portion 27 continuously on the outer peripheral edge of the annular seat plate portion 22, excessive tightening. No force is applied to the elastic seal 31 and overtightening is completely prevented.

本考案は前記説明から明らかなように、シール部材として環状の弾性シール体 と座金とが一体化されたものを用いたので取付け工数を低減することができ、ま た、弾性シール体には座金の環状座板部より突出する環状***部と座金の裾部の 端縁より突出する複数の環状リップとを備えたものとしたので、締め付けに要す る力も小さくてよいうえ弾性シール体の傷みが少なくなって従来のものより寿命 も長くなり繰り返し使用性にも優れたものとなり、さらに、この弾性シール体は 環状座板部の外周縁に設けられた座金の裾部内にあるので、シール体の剛性を格 段に高くすることができるうえに座金の縦幅によりボルトの締め付け過ぎを有効 に防止することができ、また、取付後における弾性シール体のはみ出しがなく外 観上の見栄えが良いなど種々の利点がある。 従って、本考案は従来のこの種ボルトのシール装置の問題点を解決したものと して実用的価値極めて大きいものである。 As is apparent from the above description, the present invention uses the ring-shaped elastic seal body and the washer integrated as the seal member, so that the number of mounting steps can be reduced. Since it is equipped with an annular ridge protruding from the annular seat plate and a plurality of annular lips protruding from the edge of the skirt of the washer, the force required for tightening can be small and the elastic seal body is not damaged. It has a longer life than conventional ones and has excellent repeatability.In addition, since this elastic seal is inside the hem of the washer provided on the outer peripheral edge of the annular seat plate, the seal The rigidity of the washer can be remarkably increased, and the vertical width of the washer can effectively prevent overtightening of the bolts.In addition, the elastic seal body does not stick out after mounting, and the appearance is good. There are a variety of advantages such as the stomach. Therefore, the present invention has a great practical value as a solution to the problems of the conventional bolt seal device.
