Description

本発明は、耐圧乃至は断熱などの目的でエアタイト性が要求される扉に適用して特に好適なパッキンに関する。 The present invention relates to a packing particularly suitable for application to doors that require air tightness for the purpose of pressure resistance or heat insulation.

一般に耐圧性や断熱性など扉の内，外で遮断性が求められる部屋や保管庫などの開口部に設置される扉は、その扉受けの部位に、扉の外周縁に沿って弾力性のあるパッキンが装着されることが多い。 In general, a door installed in an opening of a room or storage room that requires barrier properties inside or outside the door, such as pressure resistance or heat insulation, is elastic at the door receiving part along the outer periphery of the door. A packing is often installed.

このようなパッキンにおいて、扉受け側にパッキン装着用の溝が形成されている場合には、その溝に嵌り易く、かつ、嵌めた後にその溝から容易には離脱しない断面のパッキンが用いられる。例えば、扉受け側に「あり溝」状の逆テーパ断面の溝が設けられている場合、溝の断面の入口が溝の底より狭いため、溝の断面に合った断面形状に嵌合部を形成したゴム製やプラスチック製のパッキンであると、溝に嵌めた後、離脱し難いという利点がある一方、溝に嵌める作業に手間取る、つまり、溝に嵌まり難いという問題がある。 In such a packing, when a groove for packing attachment is formed on the door receiving side, a packing having a cross section that is easy to fit into the groove and does not easily come off from the groove after fitting is used. For example, if the door receiving side has a groove with a reverse taper cross-section, the inlet of the cross-section of the groove is narrower than the bottom of the groove, so that the fitting part has a cross-sectional shape that matches the cross-section of the groove. The formed rubber or plastic packing has an advantage that it is difficult to remove after being fitted into the groove, but there is a problem that it takes time to fit in the groove, that is, it is difficult to fit into the groove.

溝に嵌まり易いことを考えると、Ｏ−リング状断面のチューブ状のパッキンを使いたくなるが、Ｏ−リング状断面のパッキンでは、溝に嵌まった状態で扉受けの外面からの突出量が少なくなるため、十分なパッキン効果が得られないおそれがある。 Considering that it is easy to fit into a groove, it would be tempting to use a tube-shaped packing with an O-ring-shaped cross section. Therefore, a sufficient packing effect may not be obtained.

また、装着されたパッキンによって、扉を閉じたときにそのパッキンが扉の全周に亘り均等に変形しないと、扉全体において均等な遮断性能（耐熱や耐圧など）が得られない場合がある。 Further, if the packing is not uniformly deformed over the entire circumference of the door when the door is closed by the mounted packing, there may be a case where uniform shutoff performance (heat resistance, pressure resistance, etc.) cannot be obtained for the entire door.

従来、扉用のシール材乃至パッキン材として断面が中空の略三角形状、或は、充実した略三角形状のシール材やパッキン材が特許文献１〜５などとして公知であるが、いずれも上述した問題点を解決できる形態（断面形状）を備えたものではない。

Japanese Patent No. 2849502 JP-A-8-61507 Utility Model Registration No. 2558147 Japanese Examined Patent Publication No. 7-38614 Japanese Utility Model Publication No. 61-71784

本発明の発明者らは、扉受け側に設けられた逆テーパの溝に嵌り易く、また、扉に押圧されるパッキンがその全長（扉の全周）に亘って均等、かつ、柔軟に変形して完璧なパッキン効果を発揮できるパッキンを、従来技術を検討した上で鋭意研究した結果、本発明の完成を見たのである。 The inventors of the present invention easily fit into a reverse taper groove provided on the door receiving side, and the packing pressed against the door is deformed uniformly and flexibly over the entire length (the entire circumference of the door). As a result of diligent research on a conventional packing that can exhibit a perfect packing effect, the present invention has been completed.

即ち、本発明者らが上記課題を解決することを目的として完成した本発明パッキンの構成は柔軟な合成ゴム乃至合成樹脂で形成されたほぼ三角状の外面とその外面形状に沿った三角形状の内面を有する中空パッキンであって、左右斜辺の内面に断面略凹状の溝を形成すると共に、頂部の内部に断面が小径の円形状の溝を形成し、かつ、底辺外面の央部に微小凸部を形成したことを特徴とするものである。 That is, the configuration of the packing of the present invention completed by the present inventors for the purpose of solving the above problems is a substantially triangular outer surface formed of a flexible synthetic rubber or synthetic resin and a triangular shape along the outer surface shape. A hollow packing having an inner surface, a groove having a substantially concave cross section is formed on the inner surface of the left and right oblique sides, a circular groove having a small cross section is formed inside the top portion, and a micro-projection is formed at the center of the outer surface of the bottom side. The portion is formed .

本発明パッキンの外面形状は、略三角形又は正三角形である。 The outer surface shape of the packing of the present invention is a substantially triangular or equilateral triangle.

本発明パッキンは、柔軟な合成ゴム乃至合成樹脂で形成されたほぼ三角形状の外面とその外面形状に沿ったほぼ三角形状の中空内面を有するようにパッキンを形成すると共に、中空内面の左右斜辺と頂部にこのパッキンの長さ方向に沿った断面凹状の溝と小円形断面の溝を形成して構成したので、扉受け側に設けた逆テーパ状断面の溝に容易に嵌めることができる一方で脱落することがなく、また、中空内面において左右の斜辺に設けた断面略凹状の溝と頂部に設けた小円形断面の溝によって、中空三角形のパッキン全体が頂部を押圧されたとき左右均等に変形するので、高いパッキン効果を得ることができる。しかも、この三角形中空断面のパッキンは、押出成形により容易に大量生産できるので、そのコストも至って低廉になる。 The packing of the present invention forms a packing so as to have a substantially triangular outer surface formed of a flexible synthetic rubber or a synthetic resin and a substantially triangular hollow inner surface along the outer surface shape, and the left and right oblique sides of the hollow inner surface. since it is configured to form a groove and the groove of the small circular section of concave cross section for the top along the length of the packing, while it is possible to easily fitted in the groove of the reverse tapered section provided on the door receiving side without falling off, and by the groove of the small circular cross section provided in the groove and the top portion of the cross section concave provided on the hypotenuse of Oite left and right hollow inner surface, laterally equalized when the entire packing hollow triangle is pressed top Therefore, a high packing effect can be obtained. Moreover, this triangular hollow cross-section packing can be easily mass-produced by extrusion molding, so that the cost is also low.

次に、本発明パッキンの実施の形態例について、図を参照して説明する。図１は本発明パッキンの正断面図、図２は、図１のパッキンを扉受けの外面に形成した逆テーパ溝に嵌めた本発明パッキンの状態の要部の平断面図、図３は図２のパッキンと閉じた扉の当り面との関係を例示した平断面図である。 Next, an embodiment of the packing of the present invention will be described with reference to the drawings. FIG. 1 is a front sectional view of the packing of the present invention, FIG. 2 is a plan sectional view of the main portion of the packing of the present invention in which the packing of FIG. 1 is fitted in a reverse taper groove formed on the outer surface of the door receiver, and FIG. It is the plane sectional view which illustrated the relation between packing of 2 and the contact surface of the closed door.

図１において、Ｐは、外形１を大略正三角形状乃至はそれに近い形状に形成した本発明パッキンの一例で、内部が外形１とほぼ相似形をなす三角形状の中空部２に形成されている。 In FIG. 1, P is an example of the packing of the present invention in which the outer shape 1 is formed in a substantially equilateral triangular shape or a shape close thereto, and is formed in a triangular hollow portion 2 whose inside is substantially similar to the outer shape 1. .

上記パッキンＰは、一例としてシリコンゴムの押出し成形により形成するが、使用する材質はシリコンゴムに限られるものではなく、成形可能で柔軟な他の合成ゴムやプラスチック材であってもよい。また、図１に示した本発明パッキンＰは、この例では、外形の１辺が15mm前後の三角形状に成形されているが、この寸法も例示したものに限られるものではない。 The packing P is formed by extruding silicon rubber as an example, but the material used is not limited to silicon rubber, and may be other synthetic rubber or plastic material that can be molded and is flexible. Further, in this example, the packing P of the present invention shown in FIG. 1 is formed in a triangular shape having one side of the outer shape of about 15 mm, but this dimension is not limited to the illustrated one.

本発明パッキンＰは、上記の押出し成形時、その内部の中空部２の各辺に、以下に説明する形状，形態が同時に付与される。 In the present invention packing P, the shape and form described below are simultaneously imparted to each side of the hollow portion 2 at the time of extrusion molding.

即ち、図１における中空部２の左，右の斜辺の略中間部には、断面が略凹状をなす溝部3a，3bが形成されると共に、頂部には、小径の略円形断面の溝部４が形成される。そして、この実施形態例では、三角形状の底辺の外面央部に微小凸部５が形成される。 That is, groove portions 3a and 3b having a substantially concave section are formed at the substantially middle portion of the left and right hypotenuses of the hollow portion 2 in FIG. 1, and a groove portion 4 having a substantially circular cross section with a small diameter is formed at the top portion. It is formed. And in this example of embodiment, the micro convex part 5 is formed in the outer surface center part of a triangular base.

図１の本発明パッキンＰは、図２に例示した片開き扉用の扉受け６の外面6aに、後述する扉８の内面（当り面）8aにおける外周縁の内側に対応して、平断面が逆テーパ状をなすパッキン嵌入溝７が形成されているので、この溝７に、当該パッキンＰがその三角形状の底辺側から嵌入される。この嵌入において本発明パッキンＰは、柔軟性のあるシリコンゴムなどによる中空の成形品であるから、溝7への嵌入時に容易に変形して嵌入作業を容易にする。しかも、このパッキンＰにおける外形１の底辺側と２つの斜辺が、逆テーパ状の溝７にほぼ合致する形状であるため、一旦溝７に嵌入されると、溝７から容易に離脱することはない。 The packing P of the present invention shown in FIG. 1 corresponds to the outer surface 6a of the door receiver 6 for a single door illustrated in FIG. 2 and corresponds to the inner side of the outer peripheral edge of the inner surface (contact surface) 8a of the door 8 described later. Since the packing insertion groove 7 having a reverse taper shape is formed, the packing P is inserted into the groove 7 from the bottom side of the triangle. In this insertion, since the packing P of the present invention is a hollow molded product made of flexible silicone rubber or the like, it is easily deformed when fitted into the groove 7 to facilitate the fitting operation. In addition, since the bottom side of the outer shape 1 and the two oblique sides of the packing P substantially coincide with the reverse tapered groove 7, once inserted in the groove 7, it can be easily detached from the groove 7. Absent.

図２のように本発明パッキンＰが溝７に装着された状態の扉受け６に、片開き扉８が閉じられ、その内面8aが溝７に保持された本発明パッキンＰにおいて、前記溝７から突出している外形１の頂部に当接すると、当該パッキンＰは、中空部２の両斜辺が、扉８が当接する内面頂部に形成した溝部４の作用で左右均等に開き、全体として三角形が頂点から潰され加減になると共に、左右の斜辺の潰れ作用が凹状の溝3a，3bによって当該左右の斜辺に均等に伝わり、偏った潰れ変形をすることがない。 As shown in FIG. 2, in the packing P of the present invention in which the single door 8 is closed and the inner surface 8 a is held in the groove 7 in the door receiver 6 with the packing P of the present invention mounted in the groove 7, the groove 7 When the packing P comes into contact with the top of the outer shape 1 protruding from the side, both the oblique sides of the hollow portion 2 are equally opened left and right by the action of the groove 4 formed on the top of the inner surface with which the door 8 comes into contact. In addition to being crushed from the apex, the crushing action of the left and right hypotenuses is evenly transmitted to the left and right hypotenuses by the concave grooves 3a and 3b, and there is no biased deformation.

因みに、図２において、本発明パッキンＰは、扉受け６の外面から約４〜５mm程度突出しており、扉８の内面8aが当接すると図３に例示したように、約２mm前後の隙間を保って、当該パッキンＰにおける外形１の頂部が押し潰された形になる。 Incidentally, in FIG. 2, the packing P of the present invention protrudes from the outer surface of the door receiver 6 by about 4 to 5 mm, and when the inner surface 8a of the door 8 abuts, a gap of about 2 mm is formed as illustrated in FIG. The top of the outer shape 1 of the packing P is crushed.

この結果、扉受け６の外面6aと扉８の内面8aとは、本発明パッキンの三角形状をなす外形１の頂部と底辺外面の微小凸部５によってほぼ完成に遮断されるので、扉８の内，外において耐熱，耐圧等の遮断性が要求される扉におけるその扉と扉受けとの間に介在させるパッキンとしてきわめて有用である。 As a result, the outer surface 6a of the door receiver 6 and the inner surface 8a of the door 8 are almost completely cut off by the top of the outer shape 1 forming the triangular shape of the packing of the present invention and the minute convex portion 5 on the bottom outer surface. It is extremely useful as a packing that is interposed between a door and a door holder of a door that requires a barrier property such as heat resistance and pressure resistance inside and outside.

本発明は以上の通りであって、柔軟な合成ゴム乃至合成樹脂によりほぼ三角形状の外面とその外面形状に沿ったほぼ三角形状の内面を有する中空のパッキンを形成すると共に、内面の左右斜辺と頂部にこのパッキンの長さ方向に沿った溝部を形成して本発明パッキンを構成したので、扉受け側に設けた逆テーパ状断面の溝に容易に嵌って脱落することがなく、また、内面に設けた溝部によって、パッキン全体が均等に変形するので、扉の内外面における高い遮断性を実現するパッキン効果を得ることができる。 The present invention is as described above, and forms a hollow packing having a substantially triangular outer surface and a substantially triangular inner surface along the outer surface shape by a flexible synthetic rubber or synthetic resin, and the left and right oblique sides of the inner surface. Since the groove portion along the length direction of the packing is formed at the top portion to constitute the packing of the present invention, it does not easily fit into the groove of the reverse tapered cross section provided on the door receiving side, and does not fall off. Since the entire packing is uniformly deformed by the groove portion provided in, a packing effect that realizes a high barrier property on the inner and outer surfaces of the door can be obtained.

しかも、本発明パッキンは、断面形状が簡潔かつ端正であるから、成形金型も容易に作成でき、よって、高性能パッキンを低コストで大量生産することが可能である。 Moreover, since the packing of the present invention has a simple and neat cross-sectional shape, a molding die can be easily created, and high-performance packing can be mass-produced at low cost.
