Description

この発明は、車両用エンジンの吸気側に接続されるエアクリーナに関するものである。 The present invention relates to an air cleaner connected to an intake side of a vehicle engine.

従来、この種のエアクリーナとしては、例えば特許文献１に開示されるような構成が提案されている。この従来構成においては、エアクリーナのハウジングが、上面を開口した第１ケースと、その第１ケースの開口部に開閉可能に取り付けられた第２ケースとより構成されている。ハウジング内に収容されるように、第１ケース及び第２ケースの開口部間にはフィルタが着脱可能に挟持されている。両ケースの開口部の外周縁間には複数のクランプ金具が設けられ、これらのクランプ金具により両ケースが閉鎖状態に掛け止め保持されるようになっている。 Conventionally, as this type of air cleaner, for example, a configuration as disclosed in Patent Document 1 has been proposed. In this conventional configuration, the housing of the air cleaner is composed of a first case having an open upper surface and a second case attached to the opening of the first case so as to be opened and closed. A filter is detachably sandwiched between the openings of the first case and the second case so as to be accommodated in the housing. A plurality of clamp fittings are provided between the outer peripheral edges of the opening portions of both cases, and both cases are latched and held by these clamp fittings.

特開２００７−１００５６８号公報Japanese Patent Laid-Open No. 2007-1000056

以上のように、この従来のエアクリーナにおいては、両ケースの開口部の外周縁間に、両ケースを閉鎖状態に掛け止め保持するための複数のクランプ金具が設けられている。このため、部品点数が多くなり、ハウジングの構造が複雑で製作コストが高くなるという問題があった。また、第１ケースに対して第２ケースを開閉する際に、複数のクランプ金具を１つずつ係脱操作する必要があるため、両ケースの開閉が面倒で時間がかかるという問題もあった。さらに、エアクリーナはエンジンルーム内の限られたスペースに配置され、その周囲には補機類やワイヤハーネス等の各種部品が密集状態で設けられている。このため、所望の位置においてクランプ金具を操作するためのスペースを確保できない場合もあり、そのクランプ金具の設置位置ついて制約を受けることが多い。 As described above, in this conventional air cleaner, a plurality of clamp fittings for holding and holding both cases in a closed state are provided between the outer peripheral edges of the openings of both cases. For this reason, there are problems that the number of parts is increased, the structure of the housing is complicated, and the manufacturing cost is increased. In addition, when opening and closing the second case with respect to the first case, it is necessary to engage and disengage a plurality of clamp fittings one by one, and there is a problem that both cases are troublesome to open and close. Furthermore, the air cleaner is disposed in a limited space in the engine room, and various parts such as auxiliary machines and wire harnesses are provided in a dense state around the air cleaner. For this reason, there are cases where a space for operating the clamp fitting cannot be secured at a desired position, and there are many restrictions on the installation position of the clamp fitting.

加えて、前記のように、エアクリーナの周囲には各種部品が配置されているため、クランプ金具を見ることができない場合がある。このような場合は、クランプ金具の操作は手探りとなり、その操作が困難であるばかりでなく、開閉状態を誤認してしまうおそれもあった。 In addition, as described above, since various parts are arranged around the air cleaner, the clamp fitting may not be visible. In such a case, the operation of the clamp fitting is frustrated, which is not only difficult to operate, but also has the risk of misidentifying the open / closed state.

しかも、ケースのリサイクル等の廃棄処理においては、クランプ金具をケース本体から外して分別するという面倒な作業が必要であった。
この発明は、このような従来の技術に存在する問題点に着目してなされたものである。その目的は、ハウジングの構造が簡単で安価に製作することができるとともに、両ケースの開閉操作を容易かつ短時間に行うことができる等、各種の利点を有するアクリーナを提供することにある。 In addition, in the disposal process such as recycling of the case, a troublesome work of removing the clamp fitting from the case main body and separating it is necessary.
The present invention has been made paying attention to such problems existing in the prior art. An object of the present invention is to provide an cleaner having various advantages such that the structure of the housing is simple and can be manufactured at low cost, and the opening / closing operation of both cases can be performed easily and in a short time.

上記の目的を達成するために、この発明は、第１ケースと、その第１ケースの開口部に開閉可能に取り付けられる第２ケースとよりなるハウジングと、前記両ケースの開口部間に着脱可能に挟持されるフィルタとを備えたエアクリーナにおいて、前記第１ケース及び第２ケースの開口部の一側部には、相対移動可能に係合して、両ケースの一側部を閉鎖位置に結合するための結合部を設け、前記結合部は、前記第１ケースの一側部に設けられ、透孔を有する側壁、及び前記側壁からケース内方に向かって突出する係合部を備える第１結合部と、前記第２ケースの一側部に設けられ、ケース外方に向かって突出するとともに、前記第１結合部の前記透孔に挿通可能な第２結合部とにより構成され、前記第１ケース及び第２ケースの開口部の他側部には、両ケースの係合状態において、前記第１ケースに対して前記第２ケースを他側部側へ移動させる相対移動により係合して、両ケースの他側部を閉鎖位置に結合するとともに、両ケースの相対移動を規制するための規制部を設け、前記規制部における相対移動の規制の解除、及び前記第１ケースに対して前記第２ケースを一側部側へ移動させる相対移動により、両ケースは開放可能な状態となることを特徴としている。 In order to achieve the above object, the present invention is detachable between a housing comprising a first case and a second case which is attached to the opening of the first case so as to be opened and closed, and between the openings of the two cases. In the air cleaner including the filter sandwiched between the first case and the second case, one side of the opening of the first case and the second case are engaged with each other so as to be relatively movable, and one side of both cases is coupled to the closed position. A coupling portion is provided on one side of the first case, and includes a side wall having a through hole and an engagement portion protruding from the side wall toward the inside of the case. A coupling portion; and a second coupling portion that is provided on one side of the second case, protrudes outward from the case, and can be inserted into the through hole of the first coupling portion . The other side of the opening of the first case and the second case To is have you engaged state of both cases, the said second casing engaged by the relative movement for moving to the other side portion with respect to the first case, in the closed position the other side of both cases A restricting portion for restricting relative movement between the two cases is provided , the restriction of the relative movement in the restricting portion is released, and the second case is moved to one side with respect to the first case. Both cases are openable by relative movement .

従って、この発明においては、両ケースの開口部の外周縁間に複数のクランプ等を設ける必要がなく、ハウジングの構造が簡単で安価に製作することができる。また、第１ケースに対して第２ケースを開閉する場合には、両ケースの一側部に設けられた結合部及び他側部に設けられた規制部を係脱させることにより、ケースを容易に開閉することができる。また、クランプ金具が不要であるため、クランプ金具に関わる不都合を解消できる。 Therefore, in the present invention, it is not necessary to provide a plurality of clamps between the outer peripheral edges of the openings of both cases, and the housing structure can be manufactured easily and inexpensively. In addition, when opening and closing the second case with respect to the first case, the case can be easily removed by engaging / disengaging the connecting portion provided on one side of both cases and the restricting portion provided on the other side. Can be opened and closed. Moreover, since a clamp metal fitting is unnecessary, the problem regarding a clamp metal fitting can be eliminated.

以下に、この発明の第１実施形態を、図１〜図７に基づいて説明する。
図１〜図３に示すように、エアクリーナのハウジング１１は、上面を開口したほぼ四角箱形の第１ケース１２と、その第１ケース１２の上面開口部に開閉可能に取り付けられ、下面を開口した同じくほぼ四角箱形の第２ケース１３とより構成されている。第１ケース１２の開口部の外周縁には、フランジ部１２ａが形成されている。第２ケース１３の開口部の外周縁には、フランジ部１３ａが形成されている。第２ケース１３側のフランジ部１３ａの下面には、後述するフィルタ１６のシール部１６ｂに接合可能な突起としての断面ほぼ山形状の接合部１３ｂが突設されている。ハウジング１１の前面側において第１ケース１２の側壁には、大気に連通するインレット１４が形成されている。ハウジング１１の後面側において第２ケース１３の側壁には、車両用エンジンの吸気側に接続されるアウトレット１５が形成されている。 (First embodiment)
Below, 1st Embodiment of this invention is described based on FIGS.
As shown in FIGS. 1 to 3, an air cleaner housing 11 is attached to a substantially square box-shaped first case 12 having an open upper surface, and an upper surface opening portion of the first case 12 so as to be openable and closable. The second case 13 has a substantially square box shape. A flange portion 12 a is formed on the outer peripheral edge of the opening of the first case 12. A flange portion 13 a is formed on the outer peripheral edge of the opening of the second case 13. On the lower surface of the flange portion 13a on the second case 13 side, a joint portion 13b having a substantially mountain-shaped cross section as a protrusion that can be joined to a seal portion 16b of the filter 16 described later is provided. An inlet 14 communicating with the atmosphere is formed on the side wall of the first case 12 on the front side of the housing 11. An outlet 15 connected to the intake side of the vehicle engine is formed on the side wall of the second case 13 on the rear surface side of the housing 11.

図３に示すように、前記ハウジング１１内においてインレット１４とアウトレット１５との間に配置されるように、第１ケース１２及び第２ケース１３のフランジ部１２ａ，１３ａ間にはエアフィルタ１６が着脱可能に挟持されている。このフィルタ１６は、不織布をひだ状に成形してなる濾過部１６ａと、その濾過部１６ａの外周に被覆装着されたシール部１６ｂとから構成されている。そして、このエアクリーナがエンジンの吸気側に接続された状態で、エンジンが作動されたとき、エアがインレット１４から第１ケース１２内に導入されて、フィルタ１６の濾過部１６ａで濾過された後に、アウトレット１５からエンジンの吸気側に導かれる。 As shown in FIG. 3, an air filter 16 is attached and detached between the flange portions 12 a and 13 a of the first case 12 and the second case 13 so as to be disposed between the inlet 14 and the outlet 15 in the housing 11. It is pinched as possible. The filter 16 includes a filtration part 16a formed by forming a nonwoven fabric into a pleat shape, and a seal part 16b that is covered with the outer periphery of the filtration part 16a. When the air cleaner is connected to the intake side of the engine and the engine is operated, air is introduced from the inlet 14 into the first case 12 and filtered by the filter 16a of the filter 16. It is led from the outlet 15 to the intake side of the engine.

図１〜図３に示すように、前記第１ケース１２の一側部においてフランジ部１２ａの外周縁には、ほぼ横Ｕ字状をなす一対の第１結合部１７が形成されている。第１結合部１７の上部にはケース内方に向かって係合部１７ａが形成されるとともに、第１結合部１７の側壁には透孔１７ｂが形成されている。第１結合部１７と係脱可能に対応するように、第２ケース１３の一側部においてフランジ部１３ａの外周縁には、突片状をなす一対の第２結合部１８が形成されている。そして、この第２結合部１８が第１結合部１７の透孔１７ｂに挿入された後に、第２ケース１３とともに第２結合部１８が係合部１７ａに対して両ケース１２，１３の他側部側（図３の左側）へ相対移動されることにより、後述するように両ケース１２，１３が閉鎖位置に結合される。 As shown in FIGS. 1 to 3, a pair of first coupling portions 17 having a substantially U shape are formed on the outer peripheral edge of the flange portion 12 a on one side of the first case 12. An engaging portion 17 a is formed on the upper portion of the first coupling portion 17 toward the inside of the case, and a through hole 17 b is formed on the side wall of the first coupling portion 17. A pair of second coupling portions 18 having a protruding piece shape are formed on the outer peripheral edge of the flange portion 13a on one side portion of the second case 13 so as to be detachable from the first coupling portion 17. . And after this 2nd coupling | bond part 18 is inserted in the through-hole 17b of the 1st coupling | bond part 17, the 2nd coupling | bond part 18 with the 2nd case 13 is the other side of both cases 12 and 13 with respect to the engaging part 17a. By relative movement to the part side (left side in FIG. 3), both cases 12 and 13 are coupled to the closed position as will be described later.

前記第１ケース１２の他側部においてフランジ部１２ａの外周縁には、ほぼ横Ｕ字状をなす一対の第１規制部１９が形成されている。第１規制部１９の頂壁下面には、係合凸部１９ａが形成されている。第１規制部１９と係脱可能に対応するように、第２ケース１３の他側部においてフランジ部１３ａの外周縁には、突片状をなす一対の第２規制部２０が形成されている。第２規制部２０の上面には、第１規制部１９の係合凸部１９ａに係脱可能な係合凹部２０ａが形成されている。そして、両ケース１２，１３が一側部側において、結合部１７，１８の係合によって結合された状態で第２ケース１３が他側部側（図３の右側）へ移動されることにより、第２規制部２０の係合凹部２０ａが第１規制部１９の係合凸部１９ａに係合されて、両ケース１２，１３の移動が規制される。 A pair of first restricting portions 19 having a substantially U shape are formed on the outer peripheral edge of the flange portion 12a on the other side portion of the first case 12. On the lower surface of the top wall of the first restricting portion 19, an engaging convex portion 19a is formed. A pair of second restricting portions 20 having a protruding piece shape are formed on the outer peripheral edge of the flange portion 13a on the other side portion of the second case 13 so as to be detachable from the first restricting portion 19. . On the upper surface of the second restricting portion 20, an engaging recess 20a that can be engaged with and disengaged from the engaging convex portion 19a of the first restricting portion 19 is formed. And by moving the 2nd case 13 to the other side part side (right side of Drawing 3) in the state where both cases 12 and 13 were joined by engagement of joint parts 17 and 18 in one side part side, The engagement concave portion 20a of the second restricting portion 20 is engaged with the engaging convex portion 19a of the first restricting portion 19, so that the movement of both cases 12, 13 is restricted.

さて、このエアクリーナにおいて、ハウジング１１内にフィルタ１６を取り付ける場合には、開放状態の第１ケース１２内にフィルタ１６を挿入して、そのフィルタ１６のシール部１６ｂを第１ケース１２のフランジ部１２ａ上に支持する。続いて、図４に示すように、第１ケース１２に対して第２ケース１３を一側部側に向かい下降傾斜させた状態で、第２ケース１３の第２結合部１８を第１ケース１２の第１結合部１７の透孔１７ｂに内側から対向配置させる。そして、図５に示すように、第２結合部１８を第１結合部１７の透孔１７ｂに対して内側から挿入する。 In this air cleaner, when the filter 16 is mounted in the housing 11, the filter 16 is inserted into the open first case 12, and the seal portion 16b of the filter 16 is connected to the flange portion 12a of the first case 12. Support on top. Subsequently, as illustrated in FIG. 4, the second coupling portion 18 of the second case 13 is connected to the first case 12 in a state where the second case 13 is inclined downward toward the one side with respect to the first case 12. The first coupling portion 17 is arranged to face the through hole 17b from the inside. Then, as shown in FIG. 5, the second coupling portion 18 is inserted into the through hole 17 b of the first coupling portion 17 from the inside.

その後、第２ケース１３をその一側部側を中心にして傾斜状態から下方へ回動させると、図６（ａ）に示すように、第２結合部１８が第１結合部１７の係合部１７ａに対して、ケース１２，１３の他側部側に向かい移動可能に係合される。この場合、図６（ｂ）に示すように、ケース１２，１３の他側部側においては、第２ケース１３の第２規制部２０が第１ケース１２の第１規制部１９に対して係合可能に対応配置される。 Thereafter, when the second case 13 is rotated downward from the inclined state around the one side portion side, the second coupling portion 18 is engaged with the first coupling portion 17 as shown in FIG. The part 17a is engaged so as to be movable toward the other side of the case 12, 13. In this case, as shown in FIG. 6B, the second restricting portion 20 of the second case 13 is engaged with the first restricting portion 19 of the first case 12 on the other side of the cases 12 and 13. Corresponding arrangement is possible.

次いで、第２ケース１３を第１ケース１２に対して他側部側（図６の右側）に移動させると、図７（ａ）に示すように、ケース１２，１３の一側部側においては、第２結合部１８が第１結合部１７の係合部１７ａに係合した状態で、透孔１７ｂが内側に抜け出す。それとともに、図７（ｂ）に示すように、ケース１２，１３の他側部側においては、第２規制部２０の係合凹部２０ａが第１規制部１９の係合凸部１９ａに係合されて、両ケース１２，１３の移動が規制される。 Next, when the second case 13 is moved to the other side (the right side in FIG. 6) with respect to the first case 12, as shown in FIG. In a state where the second coupling portion 18 is engaged with the engaging portion 17a of the first coupling portion 17, the through hole 17b is pulled out inward. At the same time, as shown in FIG. 7B, on the other side of the cases 12 and 13, the engaging recess 20 a of the second restricting portion 20 is engaged with the engaging convex portion 19 a of the first restricting portion 19. Thus, the movement of both cases 12 and 13 is restricted.

その結果、第２ケース１３が第１ケース１２に対して閉鎖した状態に掛け止め保持される。そして、この状態において、図３に示すように、フィルタ１６のシール部１６ｂが両ケース１２，１３のフランジ部１２ａ，１３ａ間に狭着保持される。この場合、第２ケース１３のフランジ部１３ａの下面に設けられた接合部１３ｂがフィルタ１６のシール部１６ｂに接合されることにより、シール性が確保されるとともに、第２ケース１３とフィルタ１６との間の移動が規制される。 As a result, the second case 13 is latched and held in a closed state with respect to the first case 12. In this state, as shown in FIG. 3, the seal portion 16 b of the filter 16 is held tightly between the flange portions 12 a and 13 a of both cases 12 and 13. In this case, the joining portion 13b provided on the lower surface of the flange portion 13a of the second case 13 is joined to the seal portion 16b of the filter 16 to ensure sealing performance, and the second case 13 and the filter 16 Movement between is regulated.

さらに、ハウジング１１内のフィルタ１６の脱着交換時等において、第１ケース１２から第２ケース１３を開放させる場合には、前述した第２ケース１３の閉鎖時と逆の順序で、規制部１９，２０の係合状態からの解除、及び結合部１７，１８の係合状態からの解除を行えば、第２ケース１３を第１ケース１２から取り外すことができる。 Further, when the second case 13 is opened from the first case 12 when the filter 16 in the housing 11 is attached or detached, the restricting portions 19 and 19 are arranged in the reverse order to that when the second case 13 is closed. The second case 13 can be removed from the first case 12 by releasing the engagement state of 20 and releasing the engagement portions 17 and 18 from the engagement state.

従って、この実施形態のエアクリーナにおいては、以下の効果がある。
（１）第１ケース１２及び第２ケース１３の開口部の外周縁に、結合部１７，１８及び規制部１９，２０が一体に形成されている。よって、両ケース１２，１３の開口部の外周縁間に複数のクランプ金具等を設ける必要がなく、ハウジングの構造が簡単で安価に製作することができる。 Therefore, the air cleaner of this embodiment has the following effects.
(1) The coupling portions 17 and 18 and the regulating portions 19 and 20 are integrally formed on the outer peripheral edges of the opening portions of the first case 12 and the second case 13. Therefore, it is not necessary to provide a plurality of clamp fittings between the outer peripheral edges of the openings of both cases 12 and 13, and the housing structure can be manufactured easily and inexpensively.

（２）第１ケース１２に対して第２ケース１３を開閉する場合には、第２ケース１３をスライドさせて両ケース１２，１３間において結合部１７，１８及び規制部１９，２０を係脱させることにより、両ケース１２，１３を容易かつ素早く開閉させることができる。 (2) When the second case 13 is opened and closed with respect to the first case 12, the second case 13 is slid to disengage the coupling portions 17, 18 and the regulating portions 19, 20 between the cases 12, 13. By doing so, both cases 12 and 13 can be opened and closed easily and quickly.

（３）第１ケース１２に対して第２ケース１３をスライドさせるのみで、第２ケース１３を着脱させることができるため、複数のクランプ金具を操作する従来構成と比較して、その着脱が容易である。 (3) Since the second case 13 can be attached and detached simply by sliding the second case 13 relative to the first case 12, it is easier to attach and detach compared to the conventional configuration in which a plurality of clamp fittings are operated. It is.

（４）前記と同様に、第１ケース１２に対して第２ケース１３をスライドさせるのみで、第２ケース１３を着脱させることができるため、エアクリーナの周囲に補機類等が密集状態で配置されていても、第２ケース１３の上部に対する操作により、第２ケース１３の着脱を問題なく行うことができる。 (4) Similarly to the above, the second case 13 can be detached by simply sliding the second case 13 with respect to the first case 12, so that auxiliary equipment and the like are arranged in a dense state around the air cleaner. Even if it is done, by the operation with respect to the upper part of the 2nd case 13, the attachment or detachment of the 2nd case 13 can be performed without a problem.

（５）クランプ金具を用いないため、そのクランプ金具を用いた場合に生じる前述の設置位置の制約の問題は生じない。
（６）クランプ金具が不要であるため、リサイクル等のための廃棄処理において、面倒な分別作業が不要となり、その廃棄処理作業を容易に行うことができる。
(第２実施形態)
次に、この発明の第２実施形態を、前記第１実施形態と異なる部分を中心に説明する。 (5) Since the clamp metal fitting is not used, the above-mentioned problem of the restriction of the installation position that occurs when the clamp metal fitting is used does not occur.
(6) Since the clamp metal fitting is unnecessary, in the disposal processing for recycling or the like, troublesome separation work is unnecessary, and the disposal processing work can be easily performed.
(Second embodiment)
Next, a second embodiment of the present invention will be described with a focus on differences from the first embodiment.

さて、この第２実施形態においては、図８に示すように、前記第１実施形態における第２ケース１３のフランジ部１３ａの下面の接合部１３ｂに代えて、フィルタ１６のシール部１６ｂの上面に突起としての外向きのリップ部１６ｃが形成されている。そして、このリップ部１６ｃが第２ケース１３のフランジ部１３ａの下面に接合されることにより、第２ケース１３とフィルタ１６との間の移動が抑制されるようになっている。 In the second embodiment, as shown in FIG. 8, instead of the joint portion 13b on the lower surface of the flange portion 13a of the second case 13 in the first embodiment, the upper surface of the seal portion 16b of the filter 16 is provided. An outward lip portion 16c as a protrusion is formed. The lip portion 16c is joined to the lower surface of the flange portion 13a of the second case 13, so that the movement between the second case 13 and the filter 16 is suppressed.

従って、この第２実施形態においても、前記第１実施形態に記載の効果とほぼ同様な効果を得ることができる。
（変更例）
なお、この実施形態は、次のように変更して具体化することも可能である。 Therefore, also in the second embodiment, substantially the same effect as that described in the first embodiment can be obtained.
