[Industrial applications]

この考案は内燃機関等に装着されるエアクリ−ナに関する。 This invention relates to an air cleaner mounted on an internal combustion engine or the like.

【０００２】[0002]

[Prior art]

従来のエアクリ−ナは図５に示すようにボディ３０内にエレメント３１を収納しカバ−３２でボディ３０を閉塞していた。エレメント３１とカバ−３２はセンタ−ボルト３３に螺合する蝶ナット３４、３５でそれぞれ締付け固定される。 In the conventional air cleaner, as shown in FIG. 5, the element 31 is housed in the body 30 and the body 30 is closed by the cover 32. The element 31 and the cover 32 are respectively tightened and fixed by wing nuts 34 and 35 which are screwed into the center bolt 33.

【０００３】また図４に示すようにボディ４０内にエレメント４１を収納し、カバ−４２をクランプ４３でボディ４１に締付けている。エレメント４１は、その上下端に設けたパッキン４４ａ、４４ｂをボディ４０の出口側筒状部４０ａとカバ−４２に設けた筒状部４２ａにそれぞれ嵌入することによって側面でシ−ルされ保持される。Further, as shown in FIG. 4, an element 41 is housed in a body 40, and a cover 42 is clamped to the body 41 by a clamp 43. The element 41 is sealed and held on the side surface by fitting the packings 44a and 44b provided at the upper and lower ends thereof into the tubular portion 40a on the outlet side of the body 40 and the tubular portion 42a provided on the cover 42, respectively. .

[Problems to be solved by the device]

これらのエアクリ−ナはエレメントを交換や掃除のため着脱するとき二つの蝶ナットをゆるめて取外したり、ボディ全周にわたって数個取付けられているクランプを外したりしたうえ、エレメントを軸方向に長い移動距離を引き出さねばならないので着脱作業が繁瑣であり作業性が悪い。特に農業機械用等頻繁に掃除するものは影響が大である。 These air cleaners have two wing nuts that can be loosened and removed when the element is attached or detached for replacement or cleaning, and several clamps that are attached around the entire circumference of the body can be removed. Since the moving distance has to be extracted, the work of attaching and detaching is complicated and the workability is poor. Especially those that are frequently cleaned, such as those for agricultural machinery, have a great impact.

【０００５】さらにこのエアクリ−ナは例えば車両塔載用として狭いエンジンル−ムや床下、車側等に装置される場合レイアウト上の制約があり、ケ−シング端面のカバ− を外して軸方向にエレメントを引き出すだけのスペ−スの余猶がとれない場合がある。Further, this air cleaner has a layout restriction when it is installed on a narrow engine room for vehicle tower installation, under the floor, or on the vehicle side, for example, by removing the cover on the casing end face in the axial direction. In some cases, there may not be enough space to pull out the element.

【０００６】[0006]

【課題と解決するための手段】この考案のエアクリ−ナは円筒状のケ−シングの側面に矩形状の開口と、この開口を開閉自在に被う蓋体を設ける。開口の２辺の長さは円筒状エレメントの軸方向長さおよび直径よりも大とする。さらにエレメントとケ−シングの端面間にばねを設けてエレメントを押圧して固定し、ばねに一端を固定したレバ−を、ケ −シングの端面を貫通させて設け、レバ−を引張ることによりばねを縮ませてエレメントの固定を解放するようにし、レバ−の引張り位置でレバ−を係止する係止機構を設けるものである。An air cleaner according to the present invention is provided with a rectangular opening on a side surface of a cylindrical casing and a lid that covers the opening so as to be openable and closable. The length of the two sides of the opening is greater than the axial length and diameter of the cylindrical element. Further, a spring is provided between the element and the end surface of the casing to press and fix the element, and a lever whose one end is fixed to the spring is provided by penetrating the end surface of the casing, and the lever is pulled to spring the spring. The locking mechanism is provided to lock the lever at the tensioned position of the lever so as to release the fixation of the element by contracting.

[Action]

この考案のエアクリ−ナはエレメントの掃除・交換にあたり蓋体を明けてレバ −を引けば直ちにエレメントが取出せるのでエレメントの取扱作業が簡単容易である。 In the air cleaner of the present invention, when cleaning or replacing the element, the element can be immediately taken out by opening the lid and pulling the lever, so that the element can be easily handled.

【Example】

図１、図２に実施例を示す。エアクリ−ナ１は円筒状のボディ２とカバ−３とがクランプ４で締付けられてケ−シング５を形成する。ボディ２の側面に空気入口６、カバ−に空気出口７を設け、ケ−シング５内に円筒形のエレメント８を収納する。エレメント８の一方の端板９とケ−シング５の一方の端面１０との間にコイルばね１１を配置しその押圧力によってエレメント８をパッキン１２を介してカバ−３側に押付けて固定する。 An embodiment is shown in FIGS. In the air cleaner 1, a cylindrical body 2 and a cover 3 are clamped by a clamp 4 to form a casing 5. An air inlet 6 is provided on the side surface of the body 2, an air outlet 7 is provided on the cover, and a cylindrical element 8 is housed in the casing 5. A coil spring 11 is arranged between one end plate 9 of the element 8 and one end face 10 of the casing 5, and the pressing force of the coil spring 11 presses and fixes the element 8 to the cover-3 side via the packing 12.

【０００９】図２に示すようにボディ２の側面に矩形状の開口１３を設けその軸方向の辺および円周方向の辺の長さをそれぞれエレメント８の軸方向長さおよび直径より大とする。開口１３の一方縁に蓋体１４を蝶番１５で取付け、開口１３の他方側の縁に取付けたクランプ１６で締付けて開口１３を閉塞すると、蓋体１４は開口１３を被いボディ２の側面の一部となる。蓋体１４の四辺縁にはパッキン１７を取付ける。図２はエレメント８を取り外した状態を示す。As shown in FIG. 2, a rectangular opening 13 is provided on the side surface of the body 2, and the lengths of the axial side and the circumferential side thereof are larger than the axial length and the diameter of the element 8, respectively. To do. When the lid 14 is attached to one edge of the opening 13 with the hinge 15, and the opening 13 is closed by tightening with the clamp 16 attached to the other edge of the opening 13, the lid 14 covers the opening 13 and the side surface of the body 2. Become part of. The packing 17 is attached to the four edges of the lid 14. FIG. 2 shows the element 8 removed.

【００１０】図３に示すようにコイルばね１１のエレメント８側端に保持板１８を配置して握り２０を有するレバ−１９を取付け、ケ−シング５の一方の端面１０を貫通させて配置する。レバ−１９の軸部に切り欠き凹部２１を設ける。またケ−シング５の端面１０に固定されたばね２２に付勢されて端面１０に沿って移動し、レバ −１９の軸部を押圧する突出子２３を設ける。突出子２３の形状は凹部２１に嵌合する形状である。凹部２１とばね２２と突出子２３とで係止機構２４を形成する。また凹部２１はその深さが円周方向に漸減する傾斜面を備えている。As shown in FIG. 3, a holding plate 18 is arranged at the end of the coil spring 11 on the element 8 side, a lever 19 having a grip 20 is attached, and one end surface 10 of the casing 5 is penetrated and arranged. To do. A cutout recess 21 is provided in the shaft portion of the lever 19. Further, a protrusion 23 is provided which is biased by a spring 22 fixed to the end surface 10 of the casing 5 and moves along the end surface 10 to press the shaft portion of the lever 19. The shape of the protrusion 23 is a shape that fits into the recess 21. The recess 21, the spring 22, and the protrusion 23 form a locking mechanism 24. Further, the recess 21 has an inclined surface whose depth gradually decreases in the circumferential direction.

【００１１】エアクリ−ナ１のエレメント８を掃除または交換するためにエレメント８を取出すときはクランプ１６を外し蓋体１４を明け、握り２０を持ってレバ−１９を引くと、保持板１８が移動し、凹部２１が突出子２３に引懸かり係止され、コイルばね１１が縮んだままとなる。従ってエレメント８は固定状態から開放されるので開口１３から容易に取出すことができる。When removing the element 8 for cleaning or replacing the element 8 of the air cleaner 1, the clamp 16 is removed, the lid 14 is opened, the grip 20 is held, and the lever 19 is pulled. When the coil spring 11 moves, the recess 21 is hooked and locked by the protrusion 23, and the coil spring 11 remains contracted. Therefore, the element 8 is released from the fixed state and can be easily taken out from the opening 13.

【００１２】エレメント８を装着するときは開口１３からエレメント８を挿入し、握り２０をひねると、突出子２３は凹部２１の傾斜面をせり上がり係止が外れるので、コイルばね１１は伸長しエレメント８を定位置に固定する。この場合エレメント８を定位置へ誘導するため、要すれば空気出口７の内端にテ−パ７ａを付し、あるいは端板９に凹部９ａ、保持板１８に凸部１８ａを設けて組合わせるようにしてもよい。（図３参照）When the element 8 is mounted, when the element 8 is inserted through the opening 13 and the grip 20 is twisted, the protrusion 23 rises up the inclined surface of the concave portion 21 and is released from the locking, so that the coil spring 11 extends. Fix element 8 in place. In this case, in order to guide the element 8 to a fixed position, if necessary, a taper 7a is attached to the inner end of the air outlet 7, or the end plate 9 is provided with a concave portion 9a and the holding plate 18 is provided with a convex portion 18a. It may be combined. (See Figure 3)

【００１３】図１、図２に示した例のほか、図１、図２の端面１０がカバ−であり、空気出口７のある側をボディの端面とするものについても、カバ−側にコイルばね、レバ−および係止機構を設けることによりこの考案を実施することができる。さらにエレメント着脱用の開口をケ−シング側面に設けたので、日常の保守点検のためのカバ−着脱は不要となるから、ボディとカバ−とを溶接または溶着によって一体化したケ−シングであってもよく、あるいはブロ−成形法等により両端面が一体成形されたケ−シングであってもよい。In addition to the examples shown in FIGS. 1 and 2, the end face 10 of FIGS. 1 and 2 is a cover, and the end face of the body is on the side where the air outlet 7 is located, This invention can be implemented by providing a coil spring, a lever, and a locking mechanism. Furthermore, since the opening for attaching and detaching the element is provided on the side of the casing, it is not necessary to attach and detach the cover for daily maintenance and inspection. Or both ends may be integrally molded by a blow molding method or the like.

【００１４】[0014]

【考案の効果】この考案のエアクリ−ナはケ−シングの側面にエレメントの出し入れ可能な開口を設け、エレメントはばねの操作により固定できるようにしたので、日常点検にあたりエレメントの取付け取外しが容易になり、作業性が向上する。またエレメント着脱のスペースが少なくてよい。The air cleaner of the present invention has an opening on the side of the casing that allows the element to be taken in and out, and the element can be fixed by the operation of a spring, so it is easy to attach and detach the element for daily inspection. And the workability is improved. Also, the space for attaching and detaching elements is small.
