Description

【0001】
【発明の属する技術分野】
本発明は、溝部に圧入され被対象物に弾接してシールする断面略円状のゴムシール材に関するものである。
【0002】
【従来の技術】
図4,図5に示すように、例えば自動車の機械部品100に形成された溝部110に断面略円状のゴムシール材1が嵌合され、被対象物200に弾接して被対象物200との隙間をシールするものが知られている。
一般的に断面略円状のゴムシール材1は、それが嵌合される溝部110の幅Wよりも若干大きい径を設定し、ゴムシール材1を圧縮させた状態で設置するので、ゴムシール部1は溝部110の側面111,112で保持されることになる。
【0003】
したがって、溝部110の側面111,112での保持が弱い場合、ゴムシール材1が溝部110が浮いてしまうという欠点がある。特に、ゴムシール材1をエンドレスで使用し、3次元コーナーに設置した場合、この欠点は顕著に現れることになる。
【0004】
また、ゴムシール材1は上述したように断面が略円状であるように方向性がないため、ゴムシール材1をねじった状態で設置した場合には、ねじれた部分にシワが発生し、その結果、止水性を損なうという欠点も上げられる。
【0005】
これに対して、下記に示すような特許文献がある。

特開平2−256967号公報(第1図,第3図)
【0007】
特許文献1には、固定用Oリングとして保持部を設けたものが記載されているが、その保持部は溝部側面に当接するにすぎないため、浮き上がり防止対策としては不十分である。
また、特許文献2には、シリンダヘッドカバー用ガスケットとして突起部を設けガスケットの脱落防止を図ったものが記載されているが、突起部が非常に大きいために溝部に挿入するのが難しく、さらに、突起部間に断面略V字形の切込部が形成されているため溝部挿入後に、ガスケットを溝部から外に引き出す方向に力がはたらくという問題もある。
【0008】
【発明が解決しようとする課題】
そこで、本発明の目的とするところは、上述した課題を解決するものであり、溝部に対する保持力を向上し浮き上がりや脱落を防止しうるゴムシール材を提供することにある。また、目印の設置によりゴムシール材のねじれを防止することにある。
【0009】
【課題を解決するための手段】
上記の目的を達成するために、本発明の請求項1に記載のゴムシール材は、断面矩形状の溝部(110)に、略下半部が圧入され略上半部が被対象物(200)に弾接してシールする、断面略円状のゴムシール材(11)であって、
前記略下半部を前記溝部(110)に圧入した際に、前記溝部(110)の奥側に形成される2つのコーナー部(113,114)に相対向するように、凸部(13,14)をそれぞれ、前記略下半部の先端に離間させて設けたことを特徴とする。
【0010】
また請求項2に記載の発明は、請求項1に記載の発明において、前記略下半部に設けられた2つの凸部(13,14)を結ぶ線(A)に対する垂直2等分線(B)が、前記略上半部の上端と交わる部位(P)に、凹部(15)を設けたことを特徴とする。
【0011】
さらに請求項3に記載の発明は、請求項1に記載の発明において、前記略下半部に設けられた2つの凸部(13,14)を結ぶ線(A)に対する垂直2等分線(B)が、前記略上半部の上端と交わる部位(P)に、凸部(25)を設けたことを特徴とする。
【0012】
また請求項4に記載の発明は、請求項1乃至3に記載の発明において、前記断面略円状の中心(S)と、前記2つの凸部(13,14)をそれぞれ結んだ場合、両凸部(13,14)を挟む角度(θ)を略90度にしたことを特徴とする。
【0013】
また請求項5に記載の発明は、請求項1乃至4に記載の発明において、前記2つの凸部(13,14)は断面略円状に突出したものでありその曲率半径を、前記断面略円状のゴムシール材(11)の曲率半径よりも小さくしたことを特徴とする。
【0014】
なお、括弧内の記号は、図面および後述する発明の実施の形態に記載された対応要素または対応事項を示す。
【0015】
本発明のゴムシール材によれば、略上半部が被対象物に弾接してシールする断面略円状のゴムシール材を、断面矩形状の溝部に圧入した際に、溝部の奥側に形成される2つのコーナー部に相対向するように、凸部をそれぞれ、圧入側となる略下半部の先端に離間させて設けたので、溝部に対するゴムシール材の保持力が単に溝部の側面に弾接させる場合と比較して向上する。
これによって、溝部に対するゴムシール材の浮き上がりや脱落が一層防止される。
【0016】
また本発明によれば、略下半部に設けられた2つの凸部を結ぶ線に対する垂直2等分線が、略上半部の上端と交わる部位、すなわち、被対象物とのシール面に、凹部あるいは凸部を設けたので、凹部あるいは凸部を目印にして、ゴムシール材を溝部に圧入し設置することができる。
これによって、ゴムシール材のねじれを防止することができる。
また、凸部よりも凹部を設けるものの方が、略下半部に設けられた2つの凸部との識別が容易になるので、溝部に対するゴムシール材の圧入方向に間違いを生じ難くなる。
【0017】
【発明の実施の形態】
図1および図2を参照して、本発明の実施形態に係るゴムシール材について説明する。図1はゴムシール材11の外観を示す断面図であり、図2は、そのゴムシール材11を溝部110に取付けた状態を示す断面図である。なお、従来例で示したものと同一部分には同一符合を付した。
【0018】
本発明の実施形態に係るゴムシール材11は、自動車の機械部品100に形成された長手方向に延びる断面矩形状の溝部110に嵌合されている。ゴムシール材11は、ゴム様弾性体から構成された断面略円状であり、溝部110と同様に長手方向に延びている。
またゴムシール材11の径は、それが嵌合される溝部110の幅Wよりも若干大きい径に設定してあり、これにより溝部110に対して、ゴムシール材11の略下半部が圧入され、逆側の略上半部が、被対象物200に弾接して被対象物200との隙間をシールするようになっている。
なお、溝部110が形成されるものは、自動車の機械部品100に限定されるものではなく、産業資材の部品でもよく、その材質も金属製,樹脂製等特に限定されるものではない。
【0019】
そして、ゴムシール材11の略下半部の先端には、互いに離間させた状態で、2つの凸部13,14が設けられている。
略下半部の先端におけるこの凸部13,14の設置位置は、略下半部を溝部110に圧入した際に、溝部110の奥側に形成される2つのコーナー部113,114に相対向する位置になるようにしてある。
これによれば、2つの凸部13,14は、溝部110の側面111,112ではなく、溝部110の奥側に形成される2つのコーナー部113,114を埋めるようにコーナー部113,114に確実に弾接するようにしてあるので、溝部110に対するゴムシール材11の保持力が単に側面111,112に弾接させる場合と比較して向上する。
【0020】
また2つの凸部13,14は断面略円状に突出したものでありその曲率半径は、断面略円状のゴムシール材11の曲率半径よりも小さくしている。この実施形態では、凸部13,14の曲率半径をゴムシール材11の曲率半径の略1/3にしている。
そして、ゴムシール材11の断面略円状の中心Sと、2つの凸部13,14をそれぞれ結んだ場合、両凸部13,14を挟む角度θを略90度にしたものである。
【0021】
さらに略下半部に設けられた2つの凸部13,14を結ぶ線Aに対する垂直2等分線Bが、略上半部の上端と交わる部位Pには、長手方向に延びる凹部15を設けている。2つの凸部13,14と凹部15とはゴムシール材11に対して略逆Y字状に設置されている。
凹部15は、被対象物200とのシール面に設けられることになるので、溝部110と同様に長手方向に延びる凹部15を目印にして、ゴムシール材11を溝部110に圧入し設置することにより、ゴムシール材11のねじれを防止することができる。
【0022】
なお、本発明の実施形態ではゴムシール材11のシール面に凹部15を設けるようにしたが、図3に示すゴムシール材21のように、凹部15が設置された位置に、凹部15にかえて凸部25を設けるようにしてもよい。
これによっても、凸部25を目印にして、ゴムシール材11を溝部110に圧入し設置することにより、ゴムシール材11のねじれを防止することができる。
なお、凸部25よりも凹部15を設けるものの方(図1,図2)が、他の凸部13,14との識別が容易になるので、溝部110に対するゴムシール材11の圧入方向に間違いを生じ難くなる。
【0023】
【発明の効果】
本発明のゴムシール材によれば、略上半部が被対象物に弾接してシールする断面略円状のゴムシール材を、断面矩形状の溝部に圧入した際に、溝部の奥側に形成される2つのコーナー部に相対向するように、凸部をそれぞれ、圧入側となる略下半部の先端に離間させて設けたので、溝部に対するゴムシール材の保持力が単に溝部の側面に弾接させる場合と比較して向上する。
これによって、溝部に対するゴムシール材の浮き上がりや脱落が一層防止される。
【0024】
また本発明によれば、略下半部に設けられた2つの凸部を結ぶ線に対する垂直2等分線が、略上半部の上端と交わる部位、すなわち、被対象物とのシール面に、凹部あるいは凸部を設けたので、凹部あるいは凸部を目印にして、ゴムシール材を溝部に圧入し設置することができる。
これによって、ゴムシール材のねじれを防止することができる。
また、凸部よりも凹部を設けるものの方が、略下半部に設けられた2つの凸部との識別が容易になるので、溝部に対するゴムシール材の圧入方向に間違いを生じ難くなる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a rubber seal material having a substantially circular cross section, which is press-fitted into a groove and elastically contacts and seals an object.
[0002]
[Prior art]
As shown in FIGS. 4 and 5, for example, a rubber seal material 1 having a substantially circular cross section is fitted into a groove 110 formed in a mechanical component 100 of an automobile, and is elastically contacted with the object 200 to be in contact with the object 200. One that seals a gap is known.
Generally, the rubber seal material 1 having a substantially circular cross section is set to have a diameter slightly larger than the width W of the groove 110 into which the rubber seal material 1 is fitted, and is installed in a state where the rubber seal material 1 is compressed. It is held by the side surfaces 111 and 112 of the groove 110.
[0003]
Therefore, when the holding of the groove portions 110 on the side surfaces 111 and 112 is weak, the rubber seal material 1 has a disadvantage that the groove portions 110 float. In particular, when the rubber sealing material 1 is used endlessly and installed at a three-dimensional corner, this disadvantage becomes remarkable.
[0004]
Further, since the rubber seal material 1 has no directionality so that the cross section is substantially circular as described above, when the rubber seal material 1 is installed in a twisted state, wrinkles are generated in the twisted portion, and as a result, However, there is also a disadvantage that the water blocking property is impaired.
[0005]
On the other hand, there are patent documents as shown below.

JP-A-2-150575 (FIGS. 3 and 4)
[Patent Document 2]
Japanese Patent Application Laid-Open No. Hei 2-256969 (FIGS. 1 and 3)
[0007]
Patent Literature 1 discloses an O-ring provided with a holding portion as a fixing O-ring. However, the holding portion only comes into contact with the side surface of the groove portion, which is insufficient as a measure for preventing floating.
Patent Literature 2 discloses a cylinder head cover gasket provided with a protrusion to prevent the gasket from falling off.However, the protrusion is very large, so that it is difficult to insert the gasket into the groove. Since a notch having a substantially V-shaped cross section is formed between the projections, there is also a problem that a force acts in a direction in which the gasket is pulled out from the groove after the groove is inserted.
[0008]
[Problems to be solved by the invention]
Then, an object of the present invention is to solve the above-mentioned problems, and to provide a rubber seal material which can improve the holding force to a groove portion and can prevent floating and falling off. Another object of the present invention is to prevent the rubber seal material from being twisted by providing the mark.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the rubber sealing material according to claim 1 of the present invention is configured such that a substantially lower half is press-fitted into a groove (110) having a rectangular cross section and a substantially upper half is an object (200). A rubber seal material (11) having a substantially circular cross section, which elastically contacts and seals
When the substantially lower half is press-fitted into the groove (110), the projections (13, 14) are opposed to two corners (113, 114) formed on the inner side of the groove (110). 14) are provided separately from each other at the tip of the substantially lower half.
[0010]
According to a second aspect of the present invention, in the first aspect of the present invention, a perpendicular bisector (A) to a line (A) connecting the two convex portions (13, 14) provided in the substantially lower half portion is provided. B) is characterized in that a concave portion (15) is provided at a portion (P) intersecting the upper end of the substantially upper half portion.
[0011]
Further, according to a third aspect of the present invention, in the first aspect of the present invention, a perpendicular bisector (A) to a line (A) connecting the two convex portions (13, 14) provided in the substantially lower half portion is provided. B) is characterized in that a projection (25) is provided at a portion (P) intersecting the upper end of the substantially upper half.
[0012]
According to a fourth aspect of the present invention, in the first to third aspects, when the center (S) having the substantially circular cross section and the two convex portions (13, 14) are connected, respectively, The angle (θ) sandwiching the projections (13, 14) is substantially 90 degrees.
[0013]
According to a fifth aspect of the present invention, in the first to fourth aspects of the present invention, the two convex portions (13, 14) project in a substantially circular shape in cross section, and the curvature radius thereof is set to be substantially equal to the cross section. It is characterized in that it is smaller than the radius of curvature of the circular rubber seal material (11).
[0014]
The symbols in parentheses indicate corresponding elements or matters described in the drawings and embodiments of the invention described later.
[0015]
According to the rubber seal material of the present invention, when a rubber seal material having a substantially circular cross section, whose substantially upper half resiliently contacts and seals an object, is pressed into a groove having a rectangular cross section, the rubber seal is formed on the inner side of the groove. The convex portions are spaced apart from the tips of the substantially lower half portions on the press-fit side so as to oppose the two corner portions, so that the holding force of the rubber seal material with respect to the groove portion is merely elastically contacted with the side surface of the groove portion. It is improved as compared with the case where it is performed.
This further prevents the rubber seal material from rising and falling off the groove.
[0016]
Further, according to the present invention, the perpendicular bisector to the line connecting the two convex portions provided in the substantially lower half portion intersects the upper end of the substantially upper half portion, that is, at the sealing surface with the object. Since the concave portions or the convex portions are provided, the rubber seal material can be press-fitted into the groove portions and set using the concave portions or the convex portions as a mark.
Thereby, the twist of the rubber sealing material can be prevented.
In addition, the provision of the concave portion rather than the convex portion makes it easier to distinguish between the two convex portions provided in the substantially lower half portion, and thus the error in the press-fitting direction of the rubber seal material into the groove is less likely to occur.
[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
The rubber seal material according to the embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a cross-sectional view showing an appearance of the rubber seal material 11, and FIG. 2 is a cross-sectional view showing a state where the rubber seal material 11 is attached to the groove 110. The same parts as those shown in the conventional example are denoted by the same reference numerals.
[0018]
The rubber seal material 11 according to the embodiment of the present invention is fitted in a groove 110 having a rectangular cross section and extending in a longitudinal direction formed on a mechanical component 100 of an automobile. The rubber seal material 11 has a substantially circular cross section made of a rubber-like elastic body, and extends in the longitudinal direction similarly to the groove 110.
The diameter of the rubber seal material 11 is set to be slightly larger than the width W of the groove 110 into which the rubber seal material 11 is fitted, whereby the substantially lower half of the rubber seal material 11 is pressed into the groove 110, A substantially upper half portion on the opposite side elastically contacts the object 200 to seal a gap with the object 200.
The part in which the groove 110 is formed is not limited to the mechanical part 100 of an automobile, but may be a part made of an industrial material, and the material is not particularly limited, such as metal and resin.
[0019]
At the tip of the substantially lower half of the rubber seal material 11, two projections 13 and 14 are provided in a state of being separated from each other.
The positions of the projections 13 and 14 at the tip of the substantially lower half are opposite to the two corners 113 and 114 formed on the inner side of the groove 110 when the substantially lower half is pressed into the groove 110. It is in a position where you do.
According to this, the two convex portions 13 and 14 are formed not on the side surfaces 111 and 112 of the groove portion 110 but on the corner portions 113 and 114 so as to fill the two corner portions 113 and 114 formed on the inner side of the groove portion 110. Since the elastic contact is ensured, the holding force of the rubber seal material 11 with respect to the groove 110 is improved as compared with the case where the rubber seal material 11 is simply elastically contacted with the side surfaces 111 and 112.
[0020]
The two convex portions 13 and 14 project in a substantially circular cross section, and have a radius of curvature smaller than that of the rubber seal material 11 having a substantially circular cross section. In this embodiment, the radii of curvature of the projections 13 and 14 are set to approximately one third of the radius of curvature of the rubber seal material 11.
When the center S of the rubber seal material 11 having a substantially circular cross section is connected to the two protrusions 13 and 14, respectively, the angle θ between the two protrusions 13 and 14 is set to approximately 90 degrees.
[0021]
Further, a concave portion 15 extending in the longitudinal direction is provided at a portion P where a perpendicular bisector B to a line A connecting the two convex portions 13 and 14 provided in the substantially lower half portion intersects the upper end of the substantially upper half portion. ing. The two convex portions 13 and 14 and the concave portion 15 are installed in a substantially inverted Y-shape with respect to the rubber seal material 11.
Since the concave portion 15 is provided on a sealing surface with the object 200, the rubber seal material 11 is pressed into the groove portion 110 and installed by using the concave portion 15 extending in the longitudinal direction similarly to the groove portion 110 as a mark. The twist of the rubber seal material 11 can be prevented.
[0022]
In the embodiment of the present invention, the concave portion 15 is provided on the sealing surface of the rubber seal material 11. However, like the rubber seal material 21 shown in FIG. The unit 25 may be provided.
Also in this case, the rubber seal material 11 can be prevented from being twisted by press-fitting the rubber seal material 11 into the groove 110 and setting the rubber seal material 11 with the protrusion 25 as a mark.
In the case where the concave portion 15 is provided rather than the convex portion 25 (FIGS. 1 and 2), it is easier to identify the other convex portions 13 and 14. It is unlikely to occur.
[0023]
【The invention's effect】
According to the rubber seal material of the present invention, when a rubber seal material having a substantially circular cross section, whose substantially upper half resiliently contacts and seals an object, is pressed into a groove having a rectangular cross section, the rubber seal is formed on the inner side of the groove. The convex portions are spaced apart from the tips of the substantially lower half portions on the press-fit side so as to oppose the two corner portions, so that the holding force of the rubber seal material with respect to the groove portion is merely elastically contacted with the side surface of the groove portion. It is improved as compared with the case where it is performed.
This further prevents the rubber seal material from rising and falling off the groove.
[0024]
Further, according to the present invention, the perpendicular bisector to the line connecting the two convex portions provided in the substantially lower half portion intersects the upper end of the substantially upper half portion, that is, at the sealing surface with the object. Since the concave portions or the convex portions are provided, the rubber seal material can be press-fitted into the groove portions and set using the concave portions or the convex portions as a mark.
Thereby, the twist of the rubber sealing material can be prevented.
Further, the provision of the concave portion rather than the convex portion makes it easier to distinguish between the two convex portions provided in the substantially lower half portion, so that it is less likely that an error occurs in the press-fitting direction of the rubber seal material into the groove portion.
