Description

この発明は、フィルターボックスやダクト等の内部に組み込むエアフィルタの固定装置、更に詳しくは、フィルタ出し入れ口を開閉する扉部材を閉位置にすると、これと連動してエアフィルタを固定化することができるエアフィルタの固定装置に関する。   The present invention relates to a fixing device for an air filter incorporated in a filter box, a duct or the like. More specifically, when the door member for opening and closing the filter opening / closing port is set to the closed position, the air filter can be fixed in conjunction with this. The present invention relates to a fixing device for an air filter.

例えば、ビルや工場の空調や換気において用いられているエア清浄装置は、フィルタボックスやダクト等の内部エア通路にエアフィルタを組み込み、エアフィルタに対して流動するエアを通過させることにより、エアに含まれている異物をエアフィルタで捕捉し、エアの清浄化を図るようにしている。   For example, an air purifier used in air conditioning and ventilation in buildings and factories incorporates an air filter into an internal air passage such as a filter box or duct, and allows air flowing through the air filter to pass through the air. The contained foreign matter is captured by an air filter to clean the air.

上記のようなエア清浄装置において、エアフィルタは異物の捕捉と共に濾過機能が低下するため、定期的に新たなものとの取換えが必要になり、これに対応するため、エアフィルタは、フィルタボックスやダクトに対して固定と取り外しができるように取付けられている。   In the air cleaning device as described above, since the filtration function of the air filter decreases as foreign substances are captured, it is necessary to replace the air filter with a new one periodically. To cope with this, the air filter is a filter box. It is attached so that it can be fixed to and removed from the duct.

また、エアフィルタは、エア通路内に組み込んだ状態で、エア通路内の周囲に設けた固定受け部材に一面側を押付けた固定状態とし、エアフィルタと固定受け部材の間に隙間が生じないようにすることで、濾過機能が低下しないようにしなければならない。   In addition, the air filter is in a fixed state in which one side is pressed against a fixed receiving member provided around the air passage in a state where the air filter is incorporated in the air passage so that no gap is generated between the air filter and the fixed receiving member. Therefore, it is necessary to prevent the filtration function from being deteriorated.

従来、フィルタボックスやダクトに対して、エアフィルタを抜き差し自在とすると共に、固定受け部材に一面側を押付けた固定状態とするエアフィルタの固定構造は、フィルタボックスやダクトの周壁に、エアフィルタの出し入れ口と、この出し入れ口を外部から開閉する扉部材を設け、前記フィルタボックスやダクトの内部に、エアフィルタの一面側を支持する固定受け部材と、この固定受け部材とエアフィルタを抜き差しできる間隔を設けた位置に配置され、エアフィルタの挿入方向と平行に移動可能な可動部材と、前記扉部材により前記出し入れ口を閉鎖して可動部材を押し込み移動させることにより、エアフィルタ側に押付けられる押付け部材を設けた構造になっている（例えば、特許文献１参照）。   Conventionally, an air filter fixing structure in which an air filter can be freely inserted into and removed from a filter box and a duct and the one surface side is pressed against a fixed receiving member has been mounted on the peripheral wall of the filter box or duct. A door member that opens and closes the inlet / outlet port from the outside is provided, a fixed receiving member that supports one side of the air filter inside the filter box and duct, and an interval at which the fixed receiving member and the air filter can be inserted and removed. A movable member that is movable at a position parallel to the insertion direction of the air filter, and a pressing member that is pushed toward the air filter side by closing and moving the movable member by closing the inlet / outlet port by the door member. The structure is provided with a member (see, for example, Patent Document 1).

特開２０１１−２００９５号公報JP 2011-20095 A

ところで、上記のように、扉部材により可動部材をエアフィルタの挿入方向と平行に移動させ、更に、可動部材のエアフィルタの挿入方向と平行な移動によって押付け部材がエアフィルタ側へ押付け移動する構造は、長い杆状の可動部材と、二つ折りリンクによって形成された押付け部材が必要になり、構成部材の数が多くなって構造が複雑となるため、製作コストが高くつくという問題がある。   By the way, as described above, the movable member is moved in parallel with the insertion direction of the air filter by the door member, and the pressing member is pushed and moved to the air filter side by the movement of the movable member in parallel with the insertion direction of the air filter. This requires a long hook-shaped movable member and a pressing member formed by a double-folded link, which increases the number of constituent members and complicates the structure, resulting in high manufacturing costs.

また、二つ折りリンクによって形成された押付け部材の折れ曲がった先でエアフィルタを押圧する構造は、エアフィルタの一部分を線接触で押し込むため、エアフィルタに部分的な力が加わり、エアフィルタのフィルタ枠が紙製などの柔らかい材質であると、経時的にフィルタ枠の一部だけが部分的に変形するので、固定受け部材に対するエアフィルタの押付け力が弱まり、このため、固定受け部材との密着性が低下することで、エアフィルタを用いた濾過装置の濾過機能が低下するという問題がある。   In addition, the structure in which the air filter is pressed at the point where the pressing member formed by the bi-fold link is bent pushes a part of the air filter in line contact, so a partial force is applied to the air filter, and the filter frame of the air filter If the material is made of a soft material such as paper, only part of the filter frame will be partially deformed over time, so the pressing force of the air filter against the fixed receiving member will be weakened. As a result, the filtration function of a filtration device using an air filter is degraded.

そこで、この発明の課題は、エアフィルタの固定と解除が扉部材の開閉に連動して自動的に行えるだけでなく、固定受け部材に対するエアフィルタの押付け固定が、構成部材数を可能な限り少なくして実現でき、しかも、エアフィルタの幅方向全長を面で均一に押圧することで、固定受け部材との密着性を維持することができるエアフィルタの固定装置を提供することにある。   Therefore, the object of the present invention is not only to automatically fix and release the air filter in conjunction with opening and closing of the door member, but also to press and fix the air filter to the fixed receiving member as few as possible. In addition, an object of the present invention is to provide a fixing device for an air filter that can be realized and can maintain the adhesion to a fixed receiving member by uniformly pressing the entire length of the air filter in the width direction.

上記のような課題を解決するため、この発明は、エア通路形成部材の周壁に、前記内部エア通路の途中に配置するエアフィルタの出し入れ口と、この出し入れ口を外部から開閉する扉部材を設け、前記エア通路形成部材の内部に、出し入れ口から挿入したエアフィルタの一面側を支持する固定受け部材と、前記エアフィルタの他面側に可動当て金具が配置され、前記可動当て金具は、エアフィルタの面方向に沿って長く、その一端側が前記出し入れ口からエア通路形成部材の内外に出没可能となり、閉位置にある扉部材で内側に押し込まれるように配置され、扉部材で内側に押し込まれたとき、長さ方向に対して斜め移動することにより、エアフィルタを前記固定受け部材に押圧固定するようにしたものである。   In order to solve the above-described problems, the present invention is provided with a door for opening and closing an inlet / outlet of an air filter disposed in the middle of the internal air passage, and a door member for opening / closing the inlet / outlet from the outside. A stationary receiving member for supporting one side of the air filter inserted from the inlet / outlet and a movable metal fitting on the other surface of the air filter are disposed inside the air passage forming member; It is long along the surface direction of the filter, and one end side of the filter can be moved in and out of the air passage forming member from the inlet / outlet, and is arranged to be pushed inward by the door member in the closed position, and pushed inward by the door member. Then, the air filter is pressed and fixed to the fixed receiving member by moving obliquely with respect to the length direction.

上記可動当て金具は、エア通路形成部材に対する重なり片とエアフィルタの押圧片を有する断面形状に形成され、前記重なり片に傾斜長孔が長さ方向に対して傾斜するように設けられ、上記エア通路形成部材側に前記傾斜長孔が嵌る固定ピンを設け、可動当て金具が長さ方向に対して前記傾斜長孔と固定ピンによって斜め移動するようになっており、この可動当て金具にばねで上記出し入れ口からエア通路形成部材の外方に突出する方向の移動弾性が付勢した構造とすることができる。   The movable contact fitting is formed in a cross-sectional shape having an overlap piece with respect to an air passage forming member and an air filter pressing piece, and an inclined long hole is provided in the overlap piece so as to be inclined with respect to a length direction. A fixed pin into which the inclined long hole is fitted is provided on the passage forming member side, and the movable metal fitting is moved obliquely by the inclined long hole and the fixed pin with respect to the length direction. It can be set as the structure where the movement elasticity of the direction which protrudes to the outward of an air passage formation member from the said entrance / exit was urged | biased.

また、エア通路形成部材の周壁に、前記内部エア通路の途中に配置するエアフィルタの出し入れ口と、この出し入れ口を外部から開閉する扉部材を設け、前記エア通路形成部材の内部で上下の位置に、エアフィルタを抜き差しするための抜き差しケースを固定し、この抜き差しケースにおけるエアの流れ方向に対して、下流側の位置にエアフィルタの固定受け部材と上流側の位置に凸条を設け、この凸条に対して長さ方向と幅方向の移動が可能となる可動当て金具の取付け部を重ねて設け、上記可動当て金具は、凸条に対する重なり片とエアフィルタの押圧片を有する断面形状に形成され、前記凸条に傾斜長孔が長さ方向に対して傾斜するように設けられ、前記可動当て金具の重なり片に前記傾斜長孔を貫通するピンが設けられ、可動当て金具が長さ方向に対して前記傾斜長孔とピンによって斜め移動するようになっており、この可動当て金具にばねで上記出し入れ口からエア通路形成部材の外方に突出する方向の移動弾性を付勢した構造とすることができる。   In addition, an inlet / outlet port of an air filter disposed in the middle of the internal air passage and a door member for opening / closing the inlet / outlet port from the outside are provided on the peripheral wall of the air passage forming member, and the upper and lower positions are provided inside the air passage forming member. In addition, an insertion / removal case for inserting / removing the air filter is fixed, and a fixed receiving member of the air filter is provided at the downstream position with respect to the air flow direction in the insertion / removal case, and a protrusion is provided at the upstream position. A mounting portion of a movable fitting that can move in the length direction and the width direction is provided on the ridge, and the movable fitting has a cross-sectional shape having an overlapping piece on the ridge and an air filter pressing piece. The projecting ridge is provided with an inclined long hole so as to be inclined with respect to the length direction. It is designed to move obliquely with respect to the longitudinal direction by the inclined elongated hole and the pin, and this movable contact fitting is provided with a moving elasticity in a direction projecting outward from the inlet / outlet port by the spring. It is possible to have a striking structure.

ここで、上記エアフィルタは、前後面が開口するフィルタ枠の内部に、プリーツ状に折り曲げ加工されたろ材を組み込み、フィルタ枠の一面側にパッキンを設けた構造を有し、上記フィルタボックスやダクトは、その内部がエア通路となり、周壁がこのエアフィルタが納まる角筒形に形成され、前記周壁の一方側面に設けた出し入れ口は、前記エアフィルタが出し入れできる大きさに形成されている。   Here, the air filter has a structure in which a filter medium bent into a pleat shape is incorporated inside a filter frame having front and rear surfaces opened, and a packing is provided on one surface side of the filter frame, and the filter box and duct The inside is an air passage, the peripheral wall is formed in a rectangular tube shape in which the air filter is accommodated, and the inlet / outlet port provided on one side surface of the peripheral wall is formed in a size that allows the air filter to be taken in / out.

上記した扉部材は、フィルタボックスやダクトの周壁における外面に蝶番で取り付けられ、この蝶番を支点に回動することで出し入れ口を開閉し、出し入れ口を閉じることで上記可動当て金具を長さ方向に押し込み、可動当て金具は斜め移動によりエアフィルタに向けて接近動してこれを長さ方向の全長で押圧し、固定受け部材とでエアフィルタを挟んで固定することになる。   The door member described above is hinged on the outer surface of the filter box or duct, and the hinge is pivoted around the hinge to open and close the inlet / outlet and close the inlet / outlet to move the movable metal fitting in the length direction. The movable fitting is moved toward the air filter by oblique movement and pressed with the entire length in the length direction, and is fixed by sandwiching the air filter with the fixed receiving member.

この発明によると、扉部材の開閉に連動してエアフィルタの固定と解除が自動的に行え、エアフィルタの取換え作業の省力化と能率向上が図れるだけでなく、可動当て金具で直接エアフィルタを押圧固定するので、構成部材は可動当て金具と固定ピンだけでよく、部材数の削減により構造の簡素化が図れ、製作コストの低減が可能になる。   According to the present invention, the air filter can be automatically fixed and released in conjunction with the opening and closing of the door member, and not only can the labor and efficiency of the air filter replacement work be improved, but also the air filter can be directly used with a movable metal fitting. Therefore, the structural members need only be a movable metal fitting and a fixed pin, and the structure can be simplified by reducing the number of members, and the manufacturing cost can be reduced.

また、可動当て金具は、長さ方向に対して斜め移動することにより、その全長でエアフィルタを面で均一に押圧することができ、面による押圧によってエアフィルタに部分的な変形を生じさせることがなく、固定受け部材との圧接面における全面の密着性を維持することで、経時的に濾過機能が低下するのを防ぐことができる。   Further, the movable metal fitting can move obliquely with respect to the length direction so that the air filter can be uniformly pressed with the entire length thereof, and partial deformation of the air filter is caused by the pressing with the surface. In addition, by maintaining the adhesion of the entire surface on the pressure contact surface with the fixed receiving member, it is possible to prevent the filtration function from being deteriorated over time.

以下、この発明の実施の形態を図示例と共に説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１乃至図８は、エア濾過装置１とその内部に組み込み使用する、この発明に係るエアフィルタの固定装置２の第１の実施の形態を示している。   FIG. 1 to FIG. 8 show a first embodiment of an air filter 1 and an air filter fixing device 2 according to the present invention, which is incorporated in the air filter 1 and used therein.

エア濾過装置１のエア通路形成部材であるボックス本体３は、内部中空の箱形に形成され、図１の右側にエアの流入筒４と、左側にエアの流出筒５が内部と連通するように設けられ、前記流入筒４と流出筒５にはそれぞれエア供給側と流出側の蛇腹状のホースが接続される。   The box main body 3 which is an air passage forming member of the air filtration device 1 is formed in an internal hollow box shape so that the air inflow cylinder 4 on the right side of FIG. 1 and the air outflow cylinder 5 on the left side communicate with the inside. The inflow cylinder 4 and the outflow cylinder 5 are connected to an air supply side and an outflow side bellows-shaped hose, respectively.

上記ボックス本体３の内部が、流入筒４から流出筒５に向けてエアが流れるエア通路６となり、このエア通路６内で流入筒４と流出筒５間の位置にエアフィルタ（以下メインエアフィルタという）７と、その上流側にプレフィルタ８が所定の間隔を設けて組み込まれている。   The inside of the box body 3 serves as an air passage 6 through which air flows from the inflow tube 4 toward the outflow tube 5, and an air filter (hereinafter referred to as a main air filter) is located in the air passage 6 between the inflow tube 4 and the outflow tube 5. 7) and a pre-filter 8 is incorporated at a predetermined interval on the upstream side.

上記メインエアフィルタ７は、図３や図７のように、前後面が開口するフィルタ枠９の内部に、プリーツ状に折り曲げ加工されたろ材１０を組み、フィルタ枠９の下流側となる一面側の周囲にパッキン１１を設けた構造を有し、また、プレフィルタ８は、メインエアフィルタ７の上流側で大きな異物を捕捉する周知の構造を有している。   As shown in FIG. 3 and FIG. 7, the main air filter 7 is constructed by assembling a filter medium 10 bent in a pleat shape inside a filter frame 9 whose front and rear surfaces are open, and one side of the filter frame 9 on the downstream side. The pre-filter 8 has a well-known structure that captures large foreign matters on the upstream side of the main air filter 7.

なお、上記パッキン１１は、フィルタ枠９の下流側に取付けるのが一般的であるが、これとは別に固定受け部材１７の上流側に取付ける場合もある。   The packing 11 is generally attached to the downstream side of the filter frame 9, but may be attached to the upstream side of the fixed receiving member 17 separately from this.

上記ボックス本体３の周壁はこのメインエアフィルタ７及びプレフィルタ８が丁度納まる角筒形になり、メインエアフィルタ７とプレフィルタ８の組み込により、内部のエア通路５は上流側と下流側に仕切られることになる。   The peripheral wall of the box body 3 has a rectangular tube shape in which the main air filter 7 and the pre-filter 8 are just accommodated. By incorporating the main air filter 7 and the pre-filter 8, the internal air passage 5 is formed on the upstream side and the downstream side. It will be partitioned.

ボックス本体３の周壁における一方側面に、メインエアフィルタ７とプレフィルタ８を出し入れすることができる大きさの出し入れ口１２が設けられ、前記周壁における一方側面の外側に、出し入れ口１２を開閉するための扉部材１３が取り付けられている。   In order to open and close the inlet / outlet port 12 on the outer side of the one side surface of the peripheral wall, the inlet / outlet port 12 is provided on one side surface of the peripheral wall of the box body 3 so that the main air filter 7 and the prefilter 8 can be inserted and removed. The door member 13 is attached.

この扉部材１３は、出し入れ口１２を閉鎖することができる大きさを有し、一方端部の上下位置をボックス本体３に蝶番１４で取付け、蝶番１４を支点にして水平に回動することにより出し入れ口１２を開閉することができ、他端側に設けたリブボルトやクレセント１５又は他の周知固定手段を操作することにより、出し入れ口１２を閉じた状態を固定化できるようになっており、その内面には断熱材１６が貼設され、出し入れ口１２を閉じたとき、この出し入れ口１２の周縁面に断熱材１６が圧接することで、出し入れ口１２を密閉することができるようになっている。   The door member 13 has a size capable of closing the inlet / outlet opening 12, and the vertical position of one end is attached to the box body 3 with a hinge 14, and the door member 13 is rotated horizontally around the hinge 14 as a fulcrum. The entrance / exit 12 can be opened and closed, and the closed state of the entrance / exit 12 can be fixed by operating a rib bolt or crescent 15 provided on the other end side or other known fixing means. The heat insulating material 16 is stuck on the inner surface, and when the inlet / outlet port 12 is closed, the heat insulating material 16 is pressed against the peripheral surface of the inlet / outlet port 12 so that the inlet / outlet port 12 can be sealed. .

上記ボックス本体３の内部は、出し入れ口１２からメインエアフィルタ７を挿入する部分の上下間隔が、メインエアフィルタ７の上下寸法が丁度納まるように設定されていると共に、このメインエアフィルタ７を挿入する部分を挟んで下流側の位置に、メインエアフィルタ７の一面側を支持する固定受け部材１７と、同じく上流側の位置に、メインエアフィルタ７を前記固定受け部材１７に押圧固定するための固定装置２が設けられている。   The inside of the box body 3 is set so that the vertical distance of the portion where the main air filter 7 is inserted from the insertion / exit opening 12 is set so that the vertical dimension of the main air filter 7 is just fit, and the main air filter 7 is inserted. A fixed receiving member 17 that supports one surface side of the main air filter 7 at a downstream position across the portion to be fixed, and a main air filter 7 that is pressed and fixed to the fixed receiving member 17 at an upstream position. A fixing device 2 is provided.

上記固定受け部材１７は、ボックス本体３の周壁の内周に沿って、メインエアフィルタ７におけるフィルタ枠９の一面側周囲に配置するパッキン１１受けることができる枠状に形成されている。   The fixed receiving member 17 is formed in a frame shape that can receive the packing 11 disposed around the one surface side of the filter frame 9 in the main air filter 7 along the inner periphery of the peripheral wall of the box body 3.

また、上記固定装置２は、ボックス本体３の周壁における上面と下面に設けられ、固定受け部材１７との間にメインエアフィルタ７の抜き差しできる間隔を形成するように配置され、メインエアフィルタ７の抜き差し方向に沿って平行する配置になっている。   The fixing device 2 is provided on the upper surface and the lower surface of the peripheral wall of the box body 3, and is disposed so as to form a space in which the main air filter 7 can be inserted and removed between the fixing receiving member 17. The arrangement is parallel to the insertion / removal direction.

この固定装置２は、メインエアフィルタ７の抜き差し方向に沿う長い可動当て金具１８を用い、この可動当て金具１８は、後端側が前記出し入れ口１２からボックス本体３の内外に出没可能となり、閉位置にある扉部材１３で内側に押し込まれるようになっている。ここで、可動当て金具１８は、出し入れ口１２側の端部を後端、それと反対側の端部を先端という。   The fixing device 2 uses a long movable metal fitting 18 that extends along the direction in which the main air filter 7 is inserted and removed, and the movable metal fitting 18 can be retracted into and out of the box body 3 from the inlet / outlet 12 at the rear end side. The door member 13 is pushed inward. Here, in the movable metal fitting 18, the end on the side of the loading / unloading port 12 is called the rear end, and the end on the opposite side is called the front end.

上記可動当て金具１８は、図３乃至図５のように、ボックス本体３の周壁に対する水平の長い重なり片１８ａと、この重なり片１８ａの下流側縁から直角に屈曲する押圧片１８ｂを備えた断面Ｌ形の杆状に形成され、前記ボックス本体３の幅方向に納まる程度の長さを有している。   As shown in FIGS. 3 to 5, the movable metal fitting 18 has a cross section including a long horizontal overlapping piece 18a with respect to the peripheral wall of the box body 3 and a pressing piece 18b bent at a right angle from the downstream edge of the overlapping piece 18a. It is formed in an L-shaped bowl shape and has a length enough to fit in the width direction of the box body 3.

上記可動当て金具１８は、重なり片１８ａの複数箇所に傾斜長孔１９が設けられ、この傾斜長孔１９は図１の横断平面図において、出し入れ口１２の側から見て左上がりの傾斜になり、前記傾斜長孔１９を貫通する固定ピン２０が前記ボックス本体３の側に固定され、可動当て金具１８を長さ方向に押し込むと、傾斜長孔１９の長さの範囲だけ移動可能となり、傾斜長孔１９と固定ピン２０の作用で斜め移動することになる。   The movable fitting 18 is provided with inclined long holes 19 at a plurality of positions of the overlapping piece 18a. The inclined long holes 19 are inclined upward to the left when viewed from the entrance / exit 12 in the transverse plan view of FIG. When the fixed pin 20 penetrating the inclined long hole 19 is fixed to the box body 3 side and the movable fitting 18 is pushed in the length direction, the movable pin 18 can be moved within the range of the length of the inclined long hole 19. The long hole 19 and the fixing pin 20 are moved obliquely.

上記可動当て金具１８をボックス本体３内にむけて押し込むと、固定受け部材１７の側に接近する斜め移動をすることになり、メインエアフィルタ７を押圧片１８ｂで押圧することで固定し、また、可動当て金具１８をボックス本体３の出し入れ口１２側に移動させると固定受け部材１７から離反する斜め移動をし、メインエアフィルタ７の固定を解除するようになっている。   When the movable metal fitting 18 is pushed into the box body 3, it is moved obliquely toward the fixed receiving member 17, and is fixed by pressing the main air filter 7 with the pressing piece 18b. When the movable metal fitting 18 is moved toward the loading / unloading port 12 of the box body 3, it is moved obliquely away from the fixed receiving member 17 to release the main air filter 7 from being fixed.

上記可動当て金具１８は、メインエアフィルタ７の抜き差し方向に沿う幅寸法に見合う長さを有するので、メインエアフィルタ７を押圧固定したとき、押圧片１８ｂはメインエアフィルタ７の抜き差し方向に沿う幅寸法の全長を、垂直の面で均等に押圧することになり、このような押圧はメインエアフィルタ７のフィルタ枠９に部分的な変形を発生させることがなく、固定受け部材１７に対してパッキン１１を密着させることで濾過機能の低下発生を防ぐことができる。   Since the movable metal fitting 18 has a length corresponding to the width dimension along the insertion / removal direction of the main air filter 7, when the main air filter 7 is pressed and fixed, the pressing piece 18 b has a width along the insertion / removal direction of the main air filter 7. The entire length of the dimensions is pressed evenly on a vertical surface, and such pressing does not cause partial deformation of the filter frame 9 of the main air filter 7 and packing against the fixed receiving member 17. By causing 11 to adhere, it is possible to prevent the filtration function from being lowered.

上記可動当て金具１８は、先端にこの可動当て金具１８と一体に移動するように抱持して突出するように設けたコイル状のばね２１がボックス本体３の内面に当接し、この可動当て金具１８に常時出し入れ口１２からボックス本体３の外部に突出する方向の弾性が付勢されている。   A coiled spring 21 provided at the tip of the movable pad 18 so as to be held and protruded so as to move integrally with the movable pad 18 abuts against the inner surface of the box body 3. The elasticity of the direction which protrudes to the exterior of the box main body 3 from the always in / out opening 12 is urged | biased by FIG.

この可動当て金具１８は、図５のように、扉部材１３を開くとその押し込みが解かれ、ばね２１によって出し入れ口１２側に押し戻された可動当て金具１８は、傾斜長孔１９の先端側が固定ピン２０に当接して停止し、可動当て金具１８の後端が出し入れ口１２から外部に所定長さ突出した位相となり、この状態で、固定受け部材１７と押圧片１８ｂの間隔がメインエアフィルタ７の厚みよりも広くなっている。   As shown in FIG. 5, when the door member 13 is opened, the movable metal fitting 18 is released from being pushed, and the movable metal fitting 18 pushed back to the loading / unloading port 12 side by the spring 21 is fixed at the distal end side of the inclined elongated hole 19. The phase is such that the rear end of the movable fitting 18 protrudes from the loading / unloading port 12 by a predetermined length, and in this state, the distance between the fixed receiving member 17 and the pressing piece 18b is the main air filter 7. It is wider than the thickness.

また、扉部材１３を閉じて可動当て金具１８を押し込むと、図６のように、可動当て金具１８は先端側に移動するとき固定ピン２０に沿って傾斜長孔１９により傾斜移動することで、メインエアフィルタ７に向けて接近し、押圧片１８ｂがメインエアフィルタ７の上下においてフィルタ枠９を固定受け部材１７に向けて面で押圧し、固定受け部材１７とでメインエアフィルタ７を挟み込んで固定する。   Moreover, when the door member 13 is closed and the movable metal fitting 18 is pushed in, as shown in FIG. 6, when the movable metal fitting 18 moves to the front end side, the movable metal fitting 18 is inclined and moved by the inclined long hole 19 along the fixed pin 20, Approaching the main air filter 7, the pressing piece 18 b presses the filter frame 9 toward the fixed receiving member 17 on the upper and lower sides of the main air filter 7, and sandwiches the main air filter 7 with the fixed receiving member 17. Fix it.

なお、上記した扉部材１３の内面には、上下の可動当て金具１８と対応する位置に、可動当て金具１８の押し込み金具２２が固定してある。   In addition, on the inner surface of the door member 13 described above, the push-in fitting 22 of the movable fitting 18 is fixed at a position corresponding to the upper and lower movable fittings 18.

次に、図９乃至図１４は、この発明に係るエアフィルタの固定装置の第２の実施の形態を示している。なお、第１の実施の形態と同一部分には同一符号を付すことにより説明に代える。   Next, FIGS. 9 to 14 show a second embodiment of an air filter fixing device according to the present invention. In addition, it replaces with description by attaching | subjecting the same code | symbol to the same part as 1st Embodiment.

図９と図１０のように、ボックス本体３の内部で、出し入れ口１２からメインエアフィルタ７を挿入する部分の上下位置に、メインエアフィルタ７を横差しするための抜き差しケース２３が固定され、この抜き差しケース２３におけるエアの流れ方向に対して、下流側の位置にメインエアフィルタ７の固定受け部材１７と上流側の位置に固定装置２が、前記メインエアフィルタ７の挿入できる間隔を形成した状態で設けられている。   As shown in FIGS. 9 and 10, an insertion / removal case 23 for laterally inserting the main air filter 7 is fixed inside the box body 3 at a vertical position of a portion where the main air filter 7 is inserted from the insertion / exit port 12. With respect to the air flow direction in the insertion / removal case 23, a fixing receiving member 17 of the main air filter 7 is formed at a downstream position and an interval at which the fixing device 2 can be inserted into the upstream position is formed. It is provided in the state.

上記抜き差しケース２３は、上下に対称状の配置となる同一構造を有し、ボックス本体３のメインエアフィルタ７を抜き差しする方向の幅の全長にわたる長さになっており、この抜き差しケース２３に設けた固定受け部材１７は、抜き差しケース２３を形成する金属板の端部をボックス本体３の内側へ向けて直角に折り曲げることにより形成され、また、上下の抜き差しケース２３間における固定受け部材１７の上下端部間の位置に、金属板を用いた上下方向の固定受け部材が設けられ、パッキン１１の四周面を受けることができるようになっている。   The insertion / removal case 23 has the same structure that is symmetrically arranged in the vertical direction, and has a length over the entire length in the direction of inserting / removing the main air filter 7 of the box body 3. The fixed receiving member 17 is formed by bending the end portion of the metal plate forming the insertion / removal case 23 at a right angle toward the inside of the box body 3, and the upper and lower portions of the fixed reception member 17 between the upper and lower insertion / removal cases 23. A fixed receiving member in the vertical direction using a metal plate is provided at a position between the end portions so that the four circumferential surfaces of the packing 11 can be received.

第２の実施の形態の固定装置２は、図１１乃至図１４のように、抜き差しケース２３における上流側の端部位置に、メインエアフィルタ７の面方向に沿って長い断面コ字形の凸条２４をボックス本体３の内側に向けて突出するように、抜き差しケース２３を形成する金属板から一体に折り曲げることにより設け、この凸条２４に断面コ字形の可動当て金具１８を被せ、前記凸条２４のボックス本体３の内側に向く平坦面２４ａで長さ方向の複数箇所に、長さ方向に対して傾斜する傾斜長孔１９を上記第１の実施形態と同様に設け、前記可動当て金具１８に下面側へ突出するよう固定したピン２０ａを傾斜長孔１９に嵌め合わせ、前記凸条２４の内部空間に突出するピン２０ａにばね２５を取付けた構造になっている。   As shown in FIGS. 11 to 14, the fixing device 2 according to the second embodiment is a convex strip having a U-shaped cross section that is long along the surface direction of the main air filter 7 at the upstream end position of the insertion / removal case 23. 24 is provided by being integrally bent from a metal plate forming the insertion / removal case 23 so as to protrude toward the inside of the box body 3, and the protrusion 24 is covered with a movable brace 18 having a U-shaped cross section. In the same manner as in the first embodiment, inclined movable holes 19 that are inclined with respect to the length direction are provided at a plurality of positions in the length direction on the flat surface 24a facing the inside of the box body 3 of 24, and the movable metal fitting 18 is provided. A pin 20 a fixed so as to protrude to the lower surface side is fitted into the inclined elongated hole 19, and a spring 25 is attached to the pin 20 a protruding into the inner space of the ridge 24.

上記可動当て金具１８は、メインエアフィルタ７の抜き差し方向に沿う幅と同程度の長さを有し、上記凸条２４よりも少し広幅の断面形状となって長さ方向と幅方向に移動できる余裕をもって外嵌する断面コ字形となり、メインエアフィルタ７に向く垂直の長い板となる面が押圧片１８ｂになっている。   The movable metal fitting 18 has a length approximately equal to the width along the insertion / removal direction of the main air filter 7 and has a slightly wider cross-sectional shape than the ridge 24 and can move in the length direction and the width direction. The surface is a U-shaped section that fits outside with a margin, and the surface that is a long vertical plate facing the main air filter 7 is the pressing piece 18b.

上記ばね２５は、一本の線材を用い、コイル巻き部分２５ａの両端延長部２５ｂを外開きの状態にした形状となり、コイル巻き部分２５ａをピン２０ａに固定すると共に、両端延長部２５ｂを凸条２４の下流側に位置する側面に当接させ、ピン２０ａを介して可動当て金具１８をエア流れの上流側（図１１の右側）に向けて幅方向に押圧している。   The spring 25 uses a single wire, and has a shape in which both end extension portions 25b of the coil winding portion 25a are in an open state. The coil winding portion 25a is fixed to the pin 20a, and the both end extension portions 25b are convex. 24, the movable metal fitting 18 is pressed in the width direction toward the upstream side (right side in FIG. 11) of the air flow through the pin 20a.

従って、ばね２５により弾性が付勢されたピン２０ａは傾斜長孔１９の後端に戻る弾性が付勢され、このピン２０ａが固定された可動当て金具１８は、図１２のように、扉部材１３を開くとその押し込みが解かれ、ばね２５によって出し入れ口１２側に斜め移動して図１１の断面図のように押し戻され、傾斜長孔１９の後端側にピン２０ａが当接して停止し、可動当て金具１８の後端が出し入れ口１２から外部に所定長さ突出した位相となり、この状態で、固定受け部材１７と押圧片１８ｂの間隔がメインエアフィルタ７の厚みよりも広くなっている。   Therefore, the pin 20a whose elasticity is urged by the spring 25 is urged to return to the rear end of the inclined long hole 19, and the movable metal fitting 18 to which the pin 20a is fixed is a door member as shown in FIG. When the opening 13 is opened, the push-in is released, and the spring 25 is moved obliquely toward the loading / unloading port 12 and pushed back as shown in the cross-sectional view of FIG. 11, and the pin 20a comes into contact with the rear end side of the inclined long hole 19 and stops. In this state, the rear end of the movable metal fitting 18 protrudes from the loading / unloading port 12 by a predetermined length. In this state, the distance between the fixed receiving member 17 and the pressing piece 18b is wider than the thickness of the main air filter 7. .

また、図１４のように、扉部材１３を閉じると、可動当て金具１８は傾斜長孔１９とピン２０ａの作用でボックス本体３内に向けて斜め移動しながら押し込まれ、図１３の断面図のように固定受け部材１７の側に接近し、メインエアフィルタ７を押圧片１８ｂで押圧することで固定するようになっている。   Further, as shown in FIG. 14, when the door member 13 is closed, the movable metal fitting 18 is pushed into the box body 3 while being obliquely moved into the box body 3 by the action of the inclined long hole 19 and the pin 20a. Thus, it approaches to the side of the fixed receiving member 17 and is fixed by pressing the main air filter 7 with the pressing piece 18b.

なお、エア濾過装置１として、何れの実施の形態においてもエア通路形成部材としてフィルタボックスを示したが、固定装置２の組み込みは、内部をエアが流れるダクトであってもよい。   In addition, although the filter box was shown as an air passage formation member in any embodiment as the air filtration apparatus 1, incorporation of the fixing apparatus 2 may be a duct through which air flows.

この発明のエアフィルタの固定装置は、上記のような構成であり、次に第１の実施の形態を主体に用いてその作用を説明する。   The air filter fixing device according to the present invention has the above-described configuration. Next, the operation of the air filter fixing device will be described by mainly using the first embodiment.

図６と図７のように、ボックス本体３内にメインエアフィルタ７を挿入して扉部材１３を閉じた状態に保持すると、扉部材１３でばね２１が圧縮するように押し込まれた可動当て金具１８が、固定ピン２０と傾斜長孔１９の作用で斜め移動してメインエアフィルタ７に接近し、押圧片１８ｂがメインエアフィルタ７の上下においてフィルタ枠９を押圧し、固定受け部材１７とでメインエアフィルタ７を挟み込んで固定している。   As shown in FIGS. 6 and 7, when the main air filter 7 is inserted into the box body 3 and the door member 13 is held in a closed state, the movable metal fitting pressed into the spring 21 to be compressed by the door member 13. 18 is moved obliquely by the action of the fixing pin 20 and the inclined long hole 19 and approaches the main air filter 7, and the pressing piece 18 b presses the filter frame 9 above and below the main air filter 7. The main air filter 7 is sandwiched and fixed.

この状態で、流入筒４から流入したエアは、エア通路６内を流出筒５向けて流れるとき、メインエアフィルタ７のろ材１０を通過することで濾過され、清浄になったエアが流出筒５から流出し、このとき、メインエアフィルタ７の一面側周囲に設けたパッキン１１が固定受け部材１７に押付けられて圧着しているので、メインエアフィルタ７の周囲からエアが漏れるようなことがなく、エアの濾過が確実に行える。   In this state, when the air flowing in from the inflow cylinder 4 flows in the air passage 6 toward the outflow cylinder 5, it is filtered by passing through the filter medium 10 of the main air filter 7, and the cleaned air becomes the outflow cylinder 5. At this time, since the packing 11 provided around the one surface side of the main air filter 7 is pressed against the fixed receiving member 17 and crimped, air does not leak from the periphery of the main air filter 7. Air filtration can be performed reliably.

次に、メインエアフィルタ７を取り換える場合は、図１のように扉部材１３を開けばよく、扉部材１３を開くと押し込みが解かれた可動当て金具１８はばね２１で押し戻され、後端側に移動してメインエアフィルタ７から斜め移動して離反し、その押圧を解くことでメインエアフィルタ７を出し入れ口１２から取出すことができる。   Next, when the main air filter 7 is replaced, the door member 13 may be opened as shown in FIG. 1, and when the door member 13 is opened, the movable brace 18 that has been released is pushed back by the spring 21, and the rear end side is opened. The main air filter 7 can be taken out from the inlet / outlet port 12 by moving obliquely and moving away from the main air filter 7 to release the pressure.

また、新たなメインエアフィルタ７を固定受け部材１７と可動当て金具１８の間に出し入れ口１２から挿入すると、図７のように扉部材１３を閉じるようにすればよく、可動当て金具１８は扉部材１３で押し込まれることにより、メインエアフィルタ７に接近する斜め移動することでメインエアフィルタ７を押圧して固定化する。   When a new main air filter 7 is inserted between the fixed receiving member 17 and the movable metal fitting 18 through the insertion / removal port 12, the door member 13 may be closed as shown in FIG. By being pushed by the member 13, the main air filter 7 is pressed and fixed by moving obliquely closer to the main air filter 7.

なお、第２の実施の形態の固定装置２においても、扉部材１３の開閉によって可動当て金具１８は、傾斜長孔１９とピン２０ａの作用で斜め移動することになり、扉部材１３を閉めることによって図１４に示すメインエアフィルタ７の押圧固定状態と、扉部材１３を開けることによって図１２に示すメインエアフィルタ７の押圧解除状態が得られることになる。   Also in the fixing device 2 of the second embodiment, the movable metal fitting 18 is moved obliquely by the action of the inclined long hole 19 and the pin 20a by closing and opening the door member 13, and the door member 13 is closed. Thus, the pressing and fixing state of the main air filter 7 shown in FIG. 14 and the pressing release state of the main air filter 7 shown in FIG. 12 are obtained by opening the door member 13.

上記ように、第１及び第２の実施の形態の固定装置２においては、ボックス本体３に対するメインエアフィルタ７の取り換えが、扉部材１３による出し入れ口１２の開閉と出し入れ口１２からのメインエアフィルタ７の抜き差しだけで行え、扉部材１３を閉じると自動的にメインエアフィルタ７を固定化できるので、取替え作業の能率向上と省力化が図れる。   As described above, in the fixing device 2 according to the first and second embodiments, the replacement of the main air filter 7 with respect to the box body 3 is performed by opening / closing the access port 12 by the door member 13 and the main air filter from the access port 12. The main air filter 7 can be automatically fixed when the door member 13 is closed. Therefore, it is possible to improve the efficiency of the replacement work and save labor.

また、メインエアフィルタ７の押圧固定が、可動当て金具１８と固定ピン２０又はピン２０ａ及びばね２１又は２５を用いた構造になっているので、構造の簡素化と構成部材数の削減により、製作コストを低減できるという利点がある。   In addition, since the main air filter 7 is pressed and fixed using a movable metal fitting 18, a fixed pin 20 or 20a, and a spring 21 or 25, it can be manufactured by simplifying the structure and reducing the number of components. There is an advantage that the cost can be reduced.
