Description
【０００１】[0001]
この考案は、例えば内燃機関のエアクリーナその他のエアフィルタに装着され るフィルタエレメントに関する。 The present invention relates to a filter element mounted on an air cleaner or other air filter of an internal combustion engine, for example.
【０００２】[0002]
従来、内燃機関のエアクリーナに装着されるフィルタエレメントは、ひだ折り した濾材の端面と側面を枠体で矩形に囲み、ひだ折り濾材と枠体を固着し、枠体 の下端部４辺に外側に張り出す弾性体パッキンを固着し、弾性体パッキンの上面 にフランジ状の押え板を載置した角形のフィルタエレメントが知られている。こ のようなフィルタエレメントは、例えば、実開平４ー１３４４１８号公報に開示 されている。この例のフィルタエレメントは、傾斜したパッキン座を有するボデ ーとフィルタエレメントの弾性体パッキンに当接した押え板の３辺を押圧するコ の字形のリブを有するカバーとの間に挟持され弾性体パッキンがボデーのパッキ ン座の全面に密着し、空気の清浄側と非清浄側とのシールを確保している。 Conventionally, a filter element mounted on an air cleaner of an internal combustion engine surrounds the end surface and the side surface of the fold-folded filter medium with a frame in a rectangular shape, and the fold-folded filter medium and the frame body are fixed to each other. There is known a rectangular filter element in which an elastic packing which sticks out is fixed, and a flange-shaped pressing plate is placed on the upper surface of the elastic packing. Such a filter element is disclosed, for example, in Japanese Utility Model Laid-Open No. 4-134418. The filter element of this example is sandwiched between a body having an inclined packing seat and a cover having a U-shaped rib that presses the three sides of the holding plate that is in contact with the elastic body packing of the filter element. The packing is in close contact with the entire surface of the body's packing seat, ensuring a seal between the clean side and the non-clean side of the air.
【０００３】[0003]
従来のフィルタエレメントは、エアクリーナのカバーに形成された３辺のコの 字形のリブにより、フィルタエレメントのフランジ状の押え板の３辺を押圧し、 弾性体パッキンがボデーのパッキン座の全面に密着する。押え板の残り１辺に該 当する弾性体パッキンは、カバーのリブで押圧されないので、フィルタエレメン トが長期間にわたり使用されたり、エンジン等の振動を受けるとへたったり、パ ッキン座への圧縮荷重が部分的に不均一となり、パッキン座へ全面が密着しなく なりシール不良に至るという恐れがある。 In the conventional filter element, the U-shaped ribs on the three sides of the air cleaner press the three sides of the flange-shaped holding plate of the filter element, and the elastic packing closely adheres to the entire packing seat of the body. To do. The elastic packing that hits the remaining one side of the holding plate is not pressed by the ribs on the cover, so the filter element will be used for a long period of time, will be worn out when the engine is vibrated, and will not be attached to the packing seat. There is a risk that the compressive load will become partially uneven and the entire surface will not adhere to the packing seat, resulting in poor sealing.

ひだ折りした濾材の端面と側面を枠体で矩形に囲み、ひだ折り濾材と枠体を固 着し、枠体の下端部に外側に張り出す弾性体パッキンを固着し、弾性体パッキン の上面に４辺のフランジ面を有する押え金具を載置したフィルタエレメントにお いて、１辺以上のフランジ面のほぼ中央になだらかに湾曲した下向きの凸部を形 成したバネ材から成る押え金具を弾性体パッキンに載置した。 The end face and the side face of the fold-folded filter medium are surrounded by a frame in a rectangle.The fold-folded filter medium and the frame are fixed together, and the elastic packing that extends outward is fixed to the lower end of the frame, and is attached to the upper surface of the elastic packing. In a filter element on which a holding metal fitting having four side flange surfaces is mounted, a pressing metal fitting made of a spring material that forms a downwardly curved convex portion that is gently curved in the approximate center of the flange surface of one or more sides is made of an elastic body. Placed on packing.

フィルタエレメントは、エアクリーナのケーシングに挟持されると、カバーの ３辺のリブにより押え金具を押圧し弾性体パッキンの下端部全周をエアクリーナ のボデーのフィルタエレメント取付座に押圧する。カバーのリブで押圧されない １辺の押え金具は、ほぼ中央になだらかに湾曲した下向きの凸部により、弾性体 パッキンの形状変化に追従し弾性体パッキンをパッキン取付座へ均一に押圧する 。 When the filter element is sandwiched by the air cleaner casing, the ribs on the three sides of the cover press the pressing metal fittings, and the entire lower end of the elastic packing is pressed against the filter element mounting seat of the body of the air cleaner. The pressing metal fittings on one side, which are not pressed by the ribs of the cover, have a downwardly convex part that is gently curved in the center and follows the shape change of the elastic packing, and uniformly presses the elastic packing to the packing mounting seat.

The frame 3 is formed in a rectangular shape and is composed of paper side plates 6 and 7 and thin iron plate end plates 8 and 9, and the upper edges of the side plates 6 and 7 and the end plates 8 and 9 are bent inward. At the same time, the end face of the filter medium 2 is fixed to the end plates 6 and 7, and the side face is fixed to the end plates 8 and 9, respectively.
【０００７】 弾性体パッキン４は、枠体３の４辺の下端部に外側に張り出して固着されてお り、断面が逆台形状を成している。押え金具５は、バネ用圧延鋼材製で４辺のフ ランジ面を有し、矩形に形成されている。その２辺のフランジ面５ａ、５ｂの内 側には、向合ってほぼ平行な側壁１０、１１が立設している。そして、残りの２ 辺のフランジ面５ｃ、５ｄには、ほぼ中央になだらかに湾曲した下向きの凸部１ ２、１３を形成している。押え金具５は、側壁１０、１１を枠体３の側板６、７ に面するように弾性パッキン４上に載置している。The elastic packing 4 is bulged outward and fixed to the lower ends of the four sides of the frame 3 and has an inverted trapezoidal cross section. The retainer 5 is made of rolled steel for springs, has four side flange surfaces, and is formed in a rectangular shape. Side walls 10 and 11 facing each other and substantially parallel to each other are provided upright on the inner sides of the two flange surfaces 5a and 5b. Then, on the remaining flange surfaces 5c and 5d on the two sides, downwardly projecting convex portions 12 and 13 that are gently curved are formed substantially in the center. The holding metal fitting 5 is mounted on the elastic packing 4 so that the side walls 10 and 11 face the side plates 6 and 7 of the frame body 3.
【０００８】 フィルタエレメント１は、図２、図３に示すようにボデー２１、カバー２２か らなるケーシング２３に収容されてエアクリーナ２０を形成させる。ケーシング ２３は、外形がほぼ直方体状の容器である。ボデー２１は、空気の入口２４と出 口２５を有し、開放端により形成される開口部の全周縁にパッキン溝２６を設け 、空気の入口２４から出口２５からなる空気通路に、傾斜したフィルタエレメン ト取付座２７を有している。また開口部周縁には、クリップ２８を有している。 カバー２２には、段付部２９の内側に沿ってリブ３０が周縁の３辺にコの字形に 設けられている。ボデー２１のフィルタエレメント取付座２７には、フィルタエ レメント１のひだ折り濾材２の折り目が空気の流通方向と垂直になるように、フ ィルタエレメント１が載置され、パッキン溝２６には、パッキン３１が嵌入して いる。そして、ボデー２１にカバー２２が組み合わされクリップ２８で締付られ る。As shown in FIGS. 2 and 3, the filter element 1 is housed in a casing 23 composed of a body 21 and a cover 22 to form an air cleaner 20. The casing 23 is a container having a substantially rectangular parallelepiped outer shape. The body 21 has an air inlet 24 and an air outlet 25, a packing groove 26 is provided on the entire peripheral edge of the opening formed by the open end, and an inclined filter is provided in the air passage formed from the air inlet 24 to the outlet 25. It has an element mounting seat 27. A clip 28 is provided on the peripheral edge of the opening. The cover 30 is provided with ribs 30 along the inner side of the stepped portion 29 in a U-shape on three sides of the peripheral edge. The filter element mounting seat 27 of the body 21 is mounted with the filter element 1 such that the folds of the pleated filter medium 2 of the filter element 1 are perpendicular to the air flow direction, and the packing groove 26 is provided with the packing 31. Has been inserted. Then, the body 22 and the cover 22 are combined and fastened with the clip 28.
