Description

【０００１】
【発明の属する技術分野】
本発明は、車両用空調装置のエアフィルタ装着部の蓋体の取付などに適用され、合成樹脂の一体成形ヒンジを介して蓋体を開閉可能に取り付けた蓋体の取付構造に関する。
【０００２】
【従来の技術】
例えば、車両用空調装置において、外気と内気を切り替えて導入する内外気切替ケースの出口側と送風機の吸入口との間に、エアフィルタを配設し、内気及び外気の送風がエアフィルタを通過して、空気中の塵埃や悪臭成分を吸着除去する構造の空調装置が知られている（例えば、下記特許文献１を参照）。
【０００３】
【特許文献１】
特開平９−１４２１３０号公報
【０００４】
この内外気切替ケース内に装着されるエアフィルタは、使用によって塵埃や悪臭成分を吸着し汚れてくるため、所定の保守点検時には、内外気切替ケースからエアフィルタを取り出して交換する必要がある。このために、エアフィルタは、蓋体で開閉可能な挿入口からケース内に挿入し、汚れた場合には、蓋体を開いてエアフィルタを交換する構造となっている。具体的には、内外気切替ケースと蓋体が一体成形ヒンジを介して合成樹脂により一体成形されており、蓋体はこの一体成形ヒンジを介して、内外気切替ケースのフィルタの挿入口を覆って、閉鎖するように構成されている。
【０００５】
【発明が解決しようとする課題】
しかし、一般に、合成樹脂製の一体成形ヒンジは、折り曲げが可能であっても、蓋体を挿入口に対し閉鎖した折り曲げ状態では、ヒンジ部のばね弾性力によって反発力が発生し、閉鎖していた蓋体がその力により徐々に浮き上がり閉鎖状態が不完全になる虞があった。そこで、蓋体の浮き上がりを防止するために、蓋体をねじ止めするなどの固定手段が検討されたが、別部品の固定手段を使用すると、部品点数の増加につながり、また、保守点検時などに蓋体を開く際、開放作業が煩雑となる問題があった。
【０００６】
本発明は、上述の課題を解決するものであり、一体成形ヒンジを設けた蓋体であっても浮き上がりを防止して良好なシール性を確保し、簡単に開閉を行うことができる蓋体の取付構造を提供することを目的とする。
【０００７】
【課題を解決するための手段】
上記目的を達成するために、本発明の蓋体の取付構造は、蓋体が被取付部に対し一体成形ヒンジを介して合成樹脂により一体成形されてなる蓋体の取付構造において、一体成形ヒンジは帯状本体の横断方向に薄肉の曲げ部を、３箇所に設けて形成され、被取付部側の一体成形ヒンジの近傍にヒンジ嵌入部が設けられ、ヒンジ嵌入部には、蓋体を閉じて一体成形ヒンジが折り畳まれたときに一体成形ヒンジの一部が嵌入する嵌入孔が設けられ、蓋体を閉じたとき、３箇所の曲げ部のうち真ん中の曲げ部が折り畳まれた状態で、真ん中の曲げ部を先端とするヒンジ先端部がヒンジ嵌入部に嵌入されることを特徴とする。
【０００８】
ここで、被取付部に爪嵌入部を設ける共に、蓋体に爪部を突設し、蓋体を一体成形ヒンジを介して被取付部側に閉じたとき、爪部が爪嵌入部に嵌入するように構成することもできる。
【０００９】
【作用】
上記構成の蓋体の取付構造では、蓋体を被取付部に対し閉鎖したとき、その一体成形ヒンジが折り畳まれるが、３箇所の曲げ部のうち真ん中の曲げ部が折り畳まれた状態で、真ん中の曲げ部を先端とするヒンジ先端部が被取付部側のヒンジ嵌入部に嵌入される。これにより、合成樹脂製の一体成形ヒンジは、通常、閉鎖して折り曲げた状態で反発力が発生して、閉鎖していた蓋体がその力により徐々に浮き上がりやすいが、上記のように、折り畳まれた一体成形ヒンジが被取付部側のヒンジ嵌入部に嵌め込まれて保持されるため、蓋体の浮き上がりを防止し、固定ねじなどの他の部品を使用せずに、蓋体の閉鎖状態を良好に保持することができる。また、蓋体を開く場合は、ヒンジ嵌入部の嵌入孔から一体成形ヒンジの一部を外せば、蓋体を簡単に開放することができる。
【００１０】
【発明の実施の形態】
以下、本発明の一実施形態を図面に基づいて説明する。図１は本発明を適用した車両用空調装置の内外気を切り替える内外気切替ケース１の斜視図を示している。内外気切替ケース１は、上部に外気取入れ口１ａと内気取入れ口１ｂを設け、内部には図示しない切替ドアが内気と外気を切り替えて導入するように軸支される。この内外気切替ケース１の下部に、エアフィルタ１０の挿入部が設けられ、その挿入部の端部に、挿入口４が開口形成されている。
【００１１】
エアフィルタ１０の挿入口４は横長の長方形に形成され、その４辺の周縁部には、板状の縁突部５が突出して形成され、その挿入口４は後述の蓋体２によって閉鎖可能に構成される。挿入口４の縁部の上部には、蓋体２の係止片７が係止される係止部８が突設されている。内外気切替ケース１と挿入口４に被せられる蓋体２は同じ合成樹脂製であり、蓋体２は一体成形ヒンジ（インテグラルヒンジ）３を介して内外気切替ケース１と一体成形される。
【００１２】
一体成形ヒンジ３は、内外気切替ケース１の挿入口４の下側における縁部の２箇所に形成され、蓋体２はこの１対の一体成形ヒンジ３を介して上下に回動し挿入口４を閉鎖、開放する。この一体成形ヒンジ３が接続される内外気切替ケース１の下側には、板状のヒンジ嵌入部６が閉鎖時の一体成形ヒンジ３を嵌入保持するように突設される。この一体成形ヒンジ３の下側に突設された１対のヒンジ嵌入部６には、蓋体２が閉鎖状態のとき、折り畳まれた状態の一体成形ヒンジ３が嵌入可能な矩形の嵌入孔６ａが形成されている。
【００１３】
１対の一体成形ヒンジ３は、帯状本体に３箇所の曲げ部３ａ，３ｂ，３ｃをその横断方向に設けて形成される。それらの曲げ部３ａ，３ｂ，３ｃは、各々その帯状本体の横断方向に厚さ約０．３〜０．５ｍｍの溝つまり薄肉部を設けて形成され、蓋体２を上下に回動させたとき、一体成形ヒンジ３は、３箇所の曲げ部３ａ，３ｂ，３ｃを曲折してその動きに追従するように折れ曲がる。
【００１４】
挿入口４の蓋体２の上部には係止片７が２箇所に突設され、縁突部５に嵌合可能な縁凹部９が蓋体２の内側周縁部に形成され、蓋体２を挿入口４に対し閉鎖する際、その縁凹部９がケースの縁突部５に嵌着され、係止片７がケース側の係止部８に係止可能である。
【００１５】
このように構成された蓋体の取付構造では、エアフィルタ１０の交換時などにエアフィルタ１０を挿入した後、蓋体２を挿入口４に被せて閉鎖する場合、蓋体２を図４のように一体成形ヒンジ３を介して上方に回動し、蓋体２を挿入口４に対向させる。この状態で、図４のように、一体成形ヒンジ３の曲げ部３ａの近傍がヒンジ嵌入部６に接触した状態となる。そして、蓋体２をそのまま挿入口４の側に押すと、図５のように、一体成形ヒンジ３がその曲げ部３ａ，３ｂを介してさらに折れ曲がる状態となり、このとき、一体成形ヒンジ３の一部がヒンジ嵌入部６を押し下げ、ヒンジ嵌入部６は下側に弾性変形する。
【００１６】
そして、このまま蓋体２を挿入口４側に押してその縁凹部９をケース側の縁突部５に嵌め込むようにすると、一体成形ヒンジ３におけるヒンジ嵌入部６との当接部が次第に内側に移動し、終には図２にように、一体成形ヒンジ３の先端部が折れ畳んだ状態でヒンジ嵌入部６の嵌入孔６ａに嵌入する。
【００１７】
このような操作により、図２に示す如く、蓋体２は挿入口４に被さるように閉鎖され、蓋体２の一体成形ヒンジ３は、折れ畳まれた状態でヒンジ嵌入部６に嵌入して保持され、蓋体２は確実に閉鎖された状態となる。従って、このように蓋体２が閉鎖された状態で、一体成形ヒンジ３が折れ畳まれてヒンジ嵌入部６に嵌入し、その折り曲げ状態が完全に保持されるため、蓋体２が一体成形ヒンジ３の反発力（復元力）を受けることがなく、固定ねじなどの別部品を使用せずに、振動などにより蓋体２が浮き上がってくる不具合を防止することができ、内外気切替ケース１の良好なシール性を確保することができる。
【００１８】
一方、エアフィルタ１０を交換する際に蓋体２を開く場合には、ヒンジ嵌入部６を下側に曲げて、その嵌入孔６ａから一体成形ヒンジ３の一部を抜いて、一体成形ヒンジ３の保持状態を外せば、ヒンジの機能を回復させて、蓋体２を挿入口４から外して開放することができる。
【００１９】
図６〜図１０は他の実施形態の蓋体の取付構造を示している。この例では、蓋体２の一体成形ヒンジ３の隣に爪部２６を設け、閉鎖時にその爪部２６を、挿入口４の下側に設けた爪嵌入部１６に嵌入させるように構成される。上記実施形態と同様な部分については、図に上記と同じ符号を付してその説明を省略する。
【００２０】
図６に示すように、蓋体２を内外気切替ケース１に対し接続する一対の一体成形ヒンジ３の内側に、一対の爪嵌入部１６がケース１の挿入口４の下側に突設される。爪嵌入部１６には、爪部２６が嵌入可能な嵌入孔１６ａが形成されている。蓋体２の下側の縁部には、爪嵌入部１６に対応した位置に一対の爪部２６が突設され、蓋体２をケース１側の挿入口４に被せたとき、爪部２６が爪嵌入部１６の嵌入孔１６ａに嵌入される構造である。
【００２１】
このように構成された蓋体の取付構造では、エアフィルタ１０の交換時などにエアフィルタ１０を挿入した後、蓋体２を挿入口４に被せて閉鎖する場合、蓋体２を図９のように一体成形ヒンジ３を介して上方に回動し、蓋体２を挿入口４に対向させる。そして、蓋体２をそのまま挿入口４の側に押すと、図１０のように、一体成形ヒンジ３がその曲げ部３ａ，３ｂを介してさらに折れ曲がる状態となり、このとき、蓋体２側の爪部２６が爪嵌入部１６を押し下げ、ケース１側に進み、爪嵌入部１６は下側に弾性変形していく。そして、さらに蓋体２の縁凹部９をケース１側の縁突部５に嵌め込み、蓋体２を閉じていくと、図７のように、爪部２６が爪嵌入部１６の嵌入孔１６ａに嵌入し、蓋体２の閉鎖状態が保持された状態となる。
【００２２】
このように、蓋体２が挿入口４を閉鎖した状態で、爪部２６が爪嵌入部１６に嵌入し保持されるため、蓋体２が一体成形ヒンジ３の反発力（復元力）を受けて浮き上がることはなく、振動などにより蓋体２が浮き上がる不具合を防止することができ、内外気切替ケース１の良好なシール性を確保することができる。
【００２３】
一方、エアフィルタ１０を交換する際に蓋体２を開く場合には、爪嵌入部１６を下側に曲げて、その嵌入孔１６ａから爪部２６を外せば、蓋体２を挿入口４から外して開放することができる。
【００２４】
【発明の効果】
以上説明したように、本発明の蓋体の取付構造によれば、蓋体を閉じたとき、折り畳まれた一体成形ヒンジの一部を、被取付部側のヒンジ嵌入部の嵌入孔に嵌め込むことができる。これにより、折り畳まれた一体成形ヒンジが被取付部側のヒンジ嵌入部に嵌め込まれて保持されるため、通常、閉鎖して折り曲げた状態で反発力を有する一体成形ヒンジを使用しても、蓋体の浮き上がりを防止し、固定ねじなどの他の部品を使用せずに、蓋体の閉鎖状態を良好に保持することができる。また、蓋体を開く場合は、ヒンジ嵌入部の嵌入孔から一体成形ヒンジの一部を外せば、蓋体を簡単に開放することができる。

BACKGROUND OF THE INVENTION
The present invention is applied to attachment of a lid of an air filter mounting portion of a vehicle air conditioner, and the like, and relates to a lid attachment structure in which a lid is attached so as to be openable and closable via an integrally molded hinge of synthetic resin.
[0002]
[Prior art]
For example, in a vehicle air conditioner, an air filter is disposed between the outlet side of an inside / outside air switching case that switches between outside air and inside air and the suction port of the blower, and the ventilation of the inside air and outside air passes through the air filter. An air conditioner having a structure that adsorbs and removes dust and malodorous components in the air is known (see, for example, Patent Document 1 below).
[0003]
[Patent Document 1]
JP-A-9-142130 [0004]
The air filter mounted in the inside / outside air switching case adsorbs dust and malodorous components and becomes dirty by use. Therefore, it is necessary to take out the air filter from the inside / outside air switching case and replace it during a predetermined maintenance inspection. For this reason, the air filter is configured to be inserted into the case from an insertion opening that can be opened and closed by a lid, and when the air filter becomes dirty, the lid is opened to replace the air filter. Specifically, the inside / outside air switching case and the lid are integrally formed of synthetic resin via an integrally formed hinge, and the lid covers the filter insertion port of the inside / outside air switching case via the integrally formed hinge. And is configured to close.
[0005]
[Problems to be solved by the invention]
However, in general, an integrally molded hinge made of synthetic resin is closed because a repulsive force is generated by the spring elastic force of the hinge portion in a folded state in which the lid is closed with respect to the insertion opening even if it can be bent. There was a risk that the lid would gradually float by the force and the closed state would be incomplete. Therefore, in order to prevent the lid from lifting, fixing means such as screwing the lid have been studied. However, using another part fixing means leads to an increase in the number of parts, and also during maintenance inspections. When opening the lid, there is a problem that the opening operation becomes complicated.
[0006]
The present invention solves the above-mentioned problems, and even a lid provided with an integrally formed hinge prevents a lift and ensures a good sealing property, and can be easily opened and closed. An object is to provide a mounting structure.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, a lid mounting structure according to the present invention is a lid mounting structure in which a lid is integrally molded with a synthetic resin via an integrally molded hinge with respect to a mounting portion. Is formed with three thin bent parts in the transverse direction of the belt-shaped body, and a hinge insertion part is provided in the vicinity of the integrally formed hinge on the attached part side, and the lid is closed to the hinge insertion part. When the integral hinge is folded, a fitting hole is provided to insert a part of the integral hinge. When the lid is closed, the middle bent portion of the three bent portions is folded and the middle The tip of the hinge having the bent portion of the tip is inserted into the hinge insertion portion .
[0008]
Here, when the nail insertion part is provided on the attached part, the nail part is inserted into the nail insertion part when the nail part protrudes from the cover body and the cover body is closed to the attached part side via the integrally formed hinge. It can also be configured to.
[0009]
[Action]
In the lid mounting structure of the above configuration, when the lid is closed with respect to the mounted portion, the integrally formed hinge is folded, but the middle bent portion of the three bent portions is folded in the middle. hinge tip to the bending portion and the distal end is fitted into the hinge fitting part of the mounting portion. As a result, synthetic hinges made of synthetic resin usually generate a repulsive force when they are closed and folded, and the closed lid tends to lift up gradually due to the force, but it is folded as described above. Since the integrated hinge is inserted into and held in the hinge insertion part on the mounted part side, the cover body is prevented from lifting, and the cover body can be closed without using other parts such as fixing screws. It can be held well. Moreover, when opening a cover body, if a part of integral molding hinge is removed from the insertion hole of a hinge insertion part, a cover body can be open | released easily.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a perspective view of an inside / outside air switching case 1 for switching inside / outside air of a vehicle air conditioner to which the present invention is applied. The inside / outside air switching case 1 is provided with an outside air inlet 1a and an inside air inlet 1b at the top, and is pivotally supported so that a switching door (not shown) switches between the inside air and outside air. An insertion part for the air filter 10 is provided at the lower part of the inside / outside air switching case 1, and an insertion port 4 is formed at the end of the insertion part.
[0011]
The insertion port 4 of the air filter 10 is formed in a horizontally long rectangle, and a plate-like edge projection 5 is formed on the periphery of the four sides, and the insertion port 4 can be closed by a lid 2 described later. Configured. At the upper part of the edge portion of the insertion port 4, a locking portion 8 for locking the locking piece 7 of the lid 2 is projected. The inside / outside air switching case 1 and the lid 2 that covers the insertion port 4 are made of the same synthetic resin, and the lid 2 is integrally formed with the inside / outside air switching case 1 via an integrally formed hinge (integral hinge) 3.
[0012]
The integrally molded hinge 3 is formed at two locations on the lower side of the insertion port 4 of the inside / outside air switching case 1, and the lid body 2 is pivoted up and down via the pair of integrally molded hinges 3. 4 is closed and opened. On the lower side of the inside / outside air switching case 1 to which the integrally formed hinge 3 is connected, a plate-like hinge insertion portion 6 is provided so as to fit and hold the integrally formed hinge 3 when closed. A pair of hinge insertion portions 6 projecting on the lower side of the integrally formed hinge 3 has a rectangular insertion hole 6a into which the folded integrally formed hinge 3 can be inserted when the lid 2 is closed. Is formed.
[0013]
The pair of integrally formed hinges 3 is formed by providing three bent portions 3a, 3b, 3c in the transverse direction of the belt-shaped main body. Each of the bent portions 3a, 3b, 3c is formed by providing a groove having a thickness of about 0.3 to 0.5 mm, i.e., a thin portion, in the transverse direction of the belt-like main body, and rotating the lid 2 up and down. At this time, the integrally formed hinge 3 is bent so as to bend the three bent portions 3a, 3b, and 3c and follow the movement.
[0014]
At the upper part of the lid body 2 of the insertion opening 4, locking pieces 7 are projected at two locations, and an edge recess 9 that can be fitted to the edge projection 5 is formed on the inner peripheral edge of the lid body 2. Is closed with respect to the insertion port 4, the edge recess 9 is fitted into the edge protrusion 5 of the case, and the locking piece 7 can be locked to the locking portion 8 on the case side.
[0015]
In the lid mounting structure configured as described above, when the air filter 10 is inserted when the air filter 10 is replaced and the lid 2 is closed by covering the insertion port 4, the lid 2 is shown in FIG. In this manner, the lid body 2 is rotated upward via the integrally formed hinge 3 so that the lid body 2 faces the insertion port 4. In this state, as shown in FIG. 4, the vicinity of the bent portion 3 a of the integrally molded hinge 3 is in contact with the hinge insertion portion 6. Then, when the lid 2 is pushed to the insertion port 4 as it is, the integrally formed hinge 3 is further bent through the bent portions 3a and 3b as shown in FIG. The portion pushes down the hinge insertion portion 6, and the hinge insertion portion 6 is elastically deformed downward.
[0016]
Then, when the lid 2 is pushed toward the insertion port 4 as it is and the edge recess 9 is fitted into the edge projection 5 on the case side, the contact portion with the hinge insertion portion 6 in the integrally formed hinge 3 gradually becomes inward. Finally, as shown in FIG. 2, the integrated hinge 3 is inserted into the insertion hole 6a of the hinge insertion portion 6 in a folded state.
[0017]
By such an operation, as shown in FIG. 2, the lid body 2 is closed so as to cover the insertion port 4, and the integrally formed hinge 3 of the lid body 2 is fitted into the hinge insertion portion 6 in a folded state. The lid 2 is securely closed. Therefore, in the state in which the lid 2 is closed in this way, the integrally molded hinge 3 is folded and fitted into the hinge insertion portion 6, and the folded state is completely maintained. 3 without receiving a repulsive force (restoring force) 3, and without using a separate part such as a fixing screw, it is possible to prevent a problem that the lid body 2 is lifted due to vibration or the like. Good sealing performance can be ensured.
[0018]
On the other hand, when the lid 2 is opened when the air filter 10 is replaced, the hinge fitting portion 6 is bent downward, and a part of the integrally molded hinge 3 is removed from the fitting hole 6a. If the holding state is removed, the function of the hinge can be restored and the lid 2 can be removed from the insertion port 4 and opened.
[0019]
6-10 has shown the attachment structure of the cover body of other embodiment. In this example, a claw portion 26 is provided next to the integrally formed hinge 3 of the lid 2, and the claw portion 26 is configured to be fitted into a claw insertion portion 16 provided on the lower side of the insertion port 4 when closed. . About the same part as the said embodiment, the code | symbol same as the above is attached | subjected to a figure, and the description is abbreviate | omitted.
[0020]
As shown in FIG. 6, a pair of claw insertion portions 16 project from the inside of the pair of integrally formed hinges 3 that connect the lid 2 to the inside / outside air switching case 1 and below the insertion port 4 of the case 1. The The nail insertion portion 16 is formed with an insertion hole 16a into which the claw portion 26 can be inserted. A pair of claw portions 26 project from the lower edge portion of the lid body 2 at a position corresponding to the claw insertion portion 16, and when the lid body 2 is put on the insertion opening 4 on the case 1 side, the claw portion 26. Is a structure that is inserted into the insertion hole 16 a of the nail insertion portion 16.
[0021]
In the lid mounting structure configured as described above, when the air filter 10 is inserted when the air filter 10 is replaced, and the lid body 2 is closed by covering the insertion port 4, the lid body 2 is shown in FIG. In this manner, the lid body 2 is rotated upward via the integrally formed hinge 3 so that the lid body 2 faces the insertion port 4. When the lid 2 is pushed to the insertion port 4 as it is, the integrally formed hinge 3 is further bent through the bent portions 3a and 3b as shown in FIG. The part 26 pushes down the nail insertion part 16 and proceeds to the case 1 side, and the nail insertion part 16 is elastically deformed downward. Then, when the edge recess 9 of the lid 2 is further fitted into the edge projection 5 on the case 1 side and the lid 2 is closed, the claw portion 26 is inserted into the insertion hole 16a of the claw insertion portion 16 as shown in FIG. The closed state of the lid body 2 is maintained.
[0022]
Thus, since the claw portion 26 is fitted and held in the claw insertion portion 16 with the lid body 2 closing the insertion port 4, the lid body 2 receives the repulsive force (restoring force) of the integrally formed hinge 3. Therefore, it is possible to prevent a problem that the lid 2 is lifted due to vibration or the like, and to ensure a good sealing property of the inside / outside air switching case 1.
[0023]
On the other hand, when the lid body 2 is opened when the air filter 10 is replaced, the lid body 2 can be removed from the insertion port 4 by bending the claw insertion portion 16 downward and removing the claw portion 26 from the insertion hole 16a. It can be removed and opened.
[0024]
【The invention's effect】
