Description

本発明は、通気弁を収納自在な収納ボックスに取付自在な収納ボックス用カバー装置に関する。 The present invention relates to a cover device for a storage box that can be attached to a storage box in which a ventilation valve can be stored.

通気弁は、排水管内の負圧発生時に開状態となり、排水管内に空気を取り込み、スムーズな排水を促すことで、封水トラップの封水が流出してしまうトラップ切れの発生等を防止している。通気弁は、箱状の収納ボックスに収納されて伸頂通気管に連通接続する状態で設置されている（例えば、特許文献１参照）。 The vent valve opens when negative pressure is generated in the drain pipe, draws air into the drain pipe, promotes smooth drainage, and prevents the trap from breaking, which would cause the water sealed in the trap to flow out. There is. The ventilation valve is housed in a box-shaped storage box and is installed in a state where it is communicated and connected to the top ventilation pipe (see, for example, Patent Document 1).

特許文献１に記載のものでは、収納ボックスの前面部の全体が、その内部空間を開放する開放部として形成され、その開放部を閉塞するカバー部が備えられている。カバー部には、収納ボックスの外部からの空気を吸気する多数の開口部からなる吸気部が備えられ、この吸気部を通して収納ボックスの外部からの空気を吸気することで、その空気を開状態の通気弁を通して排水管内に取り込んでいる。 In the device described in Patent Document 1, the entire front part of the storage box is formed as an open part that opens the internal space, and is provided with a cover part that closes the open part. The cover part is equipped with an intake section consisting of a number of openings that take in air from outside the storage box. It is taken into the drain pipe through the ventilation valve.

特許第６２６０２３２号公報Patent No. 6260232

特許文献１に記載のものでは、収納ボックスの開放部を閉塞するカバー部に多数の開口部からなる吸気部が配設されているので、収納ボックスの外部と収納ボックスの内部空間とが吸気部を通して直接的に連通されることになる。よって、収納ボックスの外部からの空気を吸気部を通して直接的に収納ボックスの内部空間に導くことができ、その空気を排気管内に取り込むことができる。 In the device described in Patent Document 1, an intake section consisting of a large number of openings is arranged in a cover section that closes an open section of the storage box, so that the outside of the storage box and the internal space of the storage box are connected to the intake section. will be directly communicated through. Therefore, air from outside the storage box can be directly guided into the internal space of the storage box through the intake section, and the air can be taken into the exhaust pipe.

しかしながら、収納ボックスの外部と収納ボックスの内部空間とが吸気部を通して直接的に連通されるので、通気弁が開状態となった場合に、排水管における排水音が、吸気部を通して、収納ボックスの外部に直接的に伝達されてしまう。よって、排水音がそのまま収納ボックスの外部に漏れてしまい、その排水音が騒音となってしまう。 However, since the outside of the storage box and the internal space of the storage box are directly communicated through the intake part, when the ventilation valve is open, the sound of drainage in the drain pipe is transmitted through the intake part to the inside of the storage box. It is directly transmitted to the outside. Therefore, the drainage sound leaks directly to the outside of the storage box, and the drainage sound becomes noise.

この実情に鑑み、本発明の主たる課題は、収納ボックスの外部からの空気を排気管内に取り込むことができながら、収納ボックスの外部に伝達される排水音を低減することができる収納ボックス用カバー装置を提供する点にある。 In view of this situation, the main object of the present invention is to provide a cover device for a storage box that can reduce drainage sound transmitted to the outside of the storage box while allowing air from outside the storage box to be taken into the exhaust pipe. The point is to provide the following.

本発明の第１特徴構成は、通気弁を収納自在な収納ボックスの開放部を閉塞する状態で前記収納ボックスに取付自在な収納ボックス用カバー装置において、
前記開放部の少なくとも一部を開口させる第１開口部を有し、前記収納ボックスの前記開放部を閉塞する閉塞部と、
前記収納ボックスの外部からの空気を吸気自在な第２開口部を有し、その第２開口部と前記第１開口部とを連通させる状態で前記閉塞部を覆うカバー部とが備えられ、
前記第１開口部の配設位置と前記第２開口部の配設位置とが、前記収納ボックスの中央部を基準に反対側となる位置関係に設定されている点にある。 A first feature of the present invention is a storage box cover device that can be attached to a storage box in a state that closes an opening of the storage box that can store a ventilation valve.
a closing portion that has a first opening that opens at least a portion of the opening, and that closes the opening of the storage box;
a cover part having a second opening capable of freely sucking air from outside the storage box and covering the closing part in a state where the second opening and the first opening are communicated;
The arrangement position of the first opening and the arrangement position of the second opening are set in a positional relationship such that they are on opposite sides with respect to the center of the storage box.

本構成によれば、第２開口部と第１開口部とを連通させる状態で閉塞部を覆うカバー部が備えられているので、収納ボックスの外部からの空気は、カバー部の第２開口部から吸気されて第１開口部に導かれ、その第１開口部を通して収納ボックスの内部空間に到達することになる。よって、通気弁が開状態となった場合には、収納ボックスの内部空間に到達する空気を排水管内に取り込むことができる。 According to this configuration, since the cover part that covers the closed part is provided in a state where the second opening part and the first opening part are communicated with each other, air from the outside of the storage box flows through the second opening part of the cover part. Air is taken in from the storage box, guided to the first opening, and reaches the internal space of the storage box through the first opening. Therefore, when the ventilation valve is in the open state, air that reaches the internal space of the storage box can be taken into the drain pipe.

第１開口部にて開放部の少なくとも一部を開口させるものの、閉塞部が、開放部を閉塞しているので、収納ボックスの内部空間における排水音が、開放部を通して、そのまま収納ボックスの外部側に伝達されるのを防止することができる。しかも、第１開口部の配設位置と第２開口部の配設位置とが、収納ボックスの中央部を基準に反対側となる位置関係に設定されているので、第１開口部の配設位置と第２開口部の配設位置との間の距離を極力長く取ることができる。これにより、排水管における排水音が、収納ボックスの内部空間から、第１開口部及び第２開口部を経て、収納ボックスの外部に伝達されるまでの距離を長くすることができる。よって、排水音が収納ボックスの外部に伝達されるまでの過程で、排水音が分散したり、排水音が壁部等で反射されることになり、排水音の低減を図ることができ、排水音がそのまま収納ボックスの外部に漏れてしまうのを防止することができる。 Although at least a part of the open part is opened at the first opening, the closing part closes off the open part, so the sound of drainage in the internal space of the storage box passes through the open part and goes directly to the outside of the storage box. can be prevented from being transmitted to Moreover, since the arrangement position of the first opening and the arrangement position of the second opening are set to be on opposite sides with respect to the center of the storage box, the arrangement position of the first opening is The distance between the position and the arrangement position of the second opening can be made as long as possible. Thereby, the distance that drainage sound in the drain pipe is transmitted from the internal space of the storage box to the outside of the storage box via the first opening and the second opening can be increased. Therefore, in the process of the drainage sound being transmitted to the outside of the storage box, the drainage sound is dispersed and reflected by the walls, etc., which makes it possible to reduce the drainage sound. This can prevent the sound from leaking directly to the outside of the storage box.

本発明の第２特徴構成は、前記収納ボックスにおいて、前記通気弁が前記収納ボックスの下端側部位に相当する位置に配設されている場合には、前記第１開口部が、前記閉塞部において、前記収納ボックスの上端側部位に相当する位置に配設され、前記第２開口部が、前記カバー部において、前記収納ボックスの下端側部位に相当する位置に配設されている点にある。 A second characteristic configuration of the present invention is that, in the storage box, when the ventilation valve is disposed at a position corresponding to a lower end side portion of the storage box, the first opening portion is located in the closing portion. , the storage box is disposed at a position corresponding to an upper end side portion of the storage box, and the second opening portion is disposed at a position corresponding to a lower end side portion of the storage box in the cover portion.

本構成によれば、上下方向において、通気弁の配設位置と第１開口部の配設位置との位置関係が収納ボックスの中央部を基準に反対側となり、しかも、第１開口部の配設位置と第２開口部の配設位置との位置関係も収納ボックスの中央部を基準に反対側となっている。これにより、第１開口部と第２開口部との間の距離だけでなく、通気弁と第１開口部との間の距離も長く取ることができるので、排水音が収納ボックスの外部に伝達されるまでの過程で、その排水音の低減を効果的に図ることができる。 According to this configuration, in the vertical direction, the positional relationship between the arrangement position of the ventilation valve and the arrangement position of the first opening is on the opposite side with respect to the central part of the storage box, and furthermore, the arrangement position of the first opening is The positional relationship between the installation position and the installation position of the second opening is also on opposite sides with respect to the center of the storage box. This makes it possible to increase not only the distance between the first opening and the second opening, but also the distance between the ventilation valve and the first opening, so that drainage sound is transmitted to the outside of the storage box. In the process of draining water, the sound of drainage can be effectively reduced.

本発明の第３特徴構成は、前記第２開口部と前記第１開口部とを連通する連通部は、前記収納ボックスの一端側端部に延びたのち、その一端側端部にて反対側に折り返して前記収納ボックスの他端側端部に延びる蛇行状の通路を１つ又は複数備えている点にある。 A third characteristic configuration of the present invention is that the communication portion that communicates the second opening and the first opening extends to one end of the storage box, and then extends to the opposite end at the one end of the storage box. The storage box has one or more meandering passages that are folded back and extended to the other end of the storage box.

本構成によれば、第２開口部と第１開口部とを連通する連通部は、蛇行状の通路を１つ又は複数備えているので、例えば、第２開口部と第１開口部とを直線状に連通するものと比べて、第１開口部から第２開口部に排水音が伝達される距離を長く取ることができる。これにより、排水音が収納ボックスの外部に伝達されるまでの過程で、その排水音の低減を効果的に図ることができる。 According to this configuration, since the communication portion that communicates the second opening and the first opening includes one or more meandering passages, for example, the second opening and the first opening communicate with each other. Compared to the case of linear communication, the distance over which drainage sound is transmitted from the first opening to the second opening can be increased. Thereby, the drainage sound can be effectively reduced in the process until it is transmitted to the outside of the storage box.

本発明の第４特徴構成は、前記閉塞部は、固定具により前記収納ボックスの前記開放部を閉塞する状態で前記収納ボックスに対して取付自在に構成され、
前記カバー部は、前記閉塞部との係合により前記閉塞部及び前記固定具を覆う状態で前記閉塞部に対して取付自在に構成されている点にある。 A fourth characteristic configuration of the present invention is that the closing part is configured to be freely attachable to the storage box in a state where the opening part of the storage box is closed by a fixture,
The cover part is configured to be able to be attached to the closure part in a state where it covers the closure part and the fixture by engaging with the closure part.

It can be firmly attached in a fixed position, and it is possible to appropriately prevent foreign matter such as dust from entering the storage box through the opening. Moreover, since the cover part can be attached to the closure part in a state that covers the closure part and the fixture by engaging with the closure part, it is necessary to form a hole etc. in the cover part for attaching the fixture. Therefore, the shape of the fixture itself is not exposed to the outside. Therefore, as a cover device for a storage box, the external shape can be finished with a beautiful finish, and the design can also be improved.

本発明の第５特徴構成は、前記閉塞部に対して前記カバー部を取り付ける場合に、前記カバー部の姿勢が適正姿勢であると、前記閉塞部に対する前記カバー部の係合を許容し、且つ、前記カバー部の姿勢が適正姿勢以外の姿勢であると、前記閉塞部に対する前記カバー部の係合を阻害する取付姿勢調整部が備えられている点にある。 A fifth characteristic configuration of the present invention is that when the cover portion is attached to the closing portion, if the posture of the cover portion is a proper posture, the engagement of the cover portion with the closing portion is allowed, and The present invention is characterized in that an attachment attitude adjusting section is provided that inhibits engagement of the cover section with the closing section when the cover section is in a posture other than the proper posture.

本構成によれば、取付姿勢調整部を備えることで、カバー部の姿勢が適正姿勢であるときだけ、閉塞部に対するカバー部の係合を許容して、閉塞部に対してカバー部を取り付けることができる。これにより、閉塞部に対してカバー部を取り付ける場合に、カバー部の姿勢間違いを防止することができ、閉塞部に対するカバー部の取付を簡易にかつ適切に行うことができる。 According to this configuration, by providing the attachment attitude adjusting section, the cover section can be attached to the blocking section by allowing engagement of the cover section with the blocking section only when the posture of the cover section is in the proper posture. Can be done. Thereby, when attaching the cover part to the closed part, it is possible to prevent the cover part from being erroneously positioned, and it is possible to easily and appropriately attach the cover part to the closed part.

本発明の第６特徴構成は、前記閉塞部として、前記開放部の少なくとも一部を開口させる第３開口部を有し、前記収納ボックスの内部空間側に凹入する状態で前記開放部を閉塞する凹入状の第１閉塞部と、
その第１閉塞部における凹入空間の少なくとも一部を開口させる前記第１開口部を有し、前記第１閉塞部を覆う第２閉塞部とが備えられている点にある。 A sixth characteristic configuration of the present invention is that the closing portion includes a third opening that opens at least a part of the opening, and the opening portion is closed in a state recessed into the internal space side of the storage box. a recessed first closing portion;

本発明に係る収納ボックス用カバー装置の実施形態を図面に基づいて説明する。
〔第１実施形態〕
この収納ボックス用カバー装置は、図１に示すように、通気弁付き収納ボックス１に取付自在なものであり、まず、通気弁付き収納ボックス１について説明する。 Embodiments of a storage box cover device according to the present invention will be described based on the drawings.
[First embodiment]
As shown in FIG. 1, this storage box cover device is attachable to a storage box 1 with a ventilation valve. First, the storage box 1 with a ventilation valve will be explained.

通気弁付き収納ボックス１は、図２に示すように、伸頂通気管２に対して通気弁３を連通接続する状態で設置される。通気弁付き収納ボックス１は、図１に示すように、通気弁３と、その通気弁３を収納自在な収納ボックス４とが備えられ、通気弁３が、収納ボックス４に対して移動不能な状態で収納ボックス４に一体的に備えられている。 As shown in FIG. 2, the ventilation valve-equipped storage box 1 is installed with the ventilation valve 3 connected to the top ventilation pipe 2 in communication. As shown in FIG. 1, the storage box 1 with a ventilation valve includes a ventilation valve 3 and a storage box 4 in which the ventilation valve 3 can be freely stored. It is integrally provided in the storage box 4 in this state.

通気弁３は、連通接続される伸頂通気管２（図２参照）内の圧力状態等に応じて、開閉自在に構成されている。伸頂通気管２内が通常の大気圧である場合には、通気弁３が閉状態となり、伸頂通気管２内の臭気等が外部に漏れるのを防止している。伸頂通気管２内に負圧が発生した場合には、通気弁３が開状態となり、伸頂通気管２を通して排水管内に空気を取り込み、スムーズな排水を促している。伸頂通気管２内に正圧が発生した場合には、通常の大気圧の場合と同様に、通気弁３が閉状態となっている。 The vent valve 3 is configured to be openable and closable depending on the pressure state within the elongated vent pipe 2 (see FIG. 2) to which it is connected. When the inside of the top ventilation pipe 2 is at normal atmospheric pressure, the ventilation valve 3 is in a closed state to prevent odor and the like inside the top ventilation pipe 2 from leaking to the outside. When negative pressure is generated in the top ventilation pipe 2, the ventilation valve 3 is opened, and air is taken into the drain pipe through the top ventilation pipe 2, thereby promoting smooth drainage. When positive pressure is generated within the elongated top vent pipe 2, the vent valve 3 is in a closed state, as in the case of normal atmospheric pressure.

通気弁３の構成について、簡単に説明する。通気弁３は、図１及び図２に示すように、伸頂通気管２に連通接続自在な円筒状の通気弁本体部３１と、弁体やその弁体を開閉するための開閉機構を有する円形状の通気弁ユニット３２と、その通気弁ユニット３２の上部を覆う円形状の通気弁カバー部３３とが備えられている。 The configuration of the ventilation valve 3 will be briefly explained. As shown in FIGS. 1 and 2, the vent valve 3 has a cylindrical vent valve main body 31 that can be freely connected to the elongated vent pipe 2, a valve body, and an opening/closing mechanism for opening and closing the valve body. A circular vent valve unit 32 and a circular vent valve cover portion 33 that covers the top of the vent valve unit 32 are provided.

通気弁本体部３１は、図２に示すように、下方側部位３１ａと中間部位３１ｂと上方側部位３１ｃとが備えられている。下方側部位３１ａは、伸頂通気管２の外径と同じ大きさの内径を有する円筒状に形成され、伸頂通気管２に外嵌する状態で伸頂通気管２に連通接続自在に構成されている。中間部位３１ｂは、下方側部位３１ａ及び上方側部位３１ｃよりも小径の円筒状に形成され、その外面部が凹入溝状に形成されている。上方側部位３１ｃも円筒状に形成され、通気弁ユニット３２を内嵌させる状態で通気弁ユニット３２を装着自在に構成されている。 As shown in FIG. 2, the vent valve main body portion 31 includes a lower side portion 31a, an intermediate portion 31b, and an upper side portion 31c. The lower side portion 31a is formed into a cylindrical shape having an inner diameter that is the same as the outer diameter of the elongated apex vent pipe 2, and is configured to be freely connected to the elongated apex vent pipe 2 in a state where it is fitted onto the elongated apex vent pipe 2. has been done. The intermediate portion 31b is formed in a cylindrical shape with a smaller diameter than the lower side portion 31a and the upper side portion 31c, and the outer surface thereof is formed in a recessed groove shape. The upper part 31c is also formed in a cylindrical shape, and is configured such that the vent valve unit 32 can be freely attached thereto by fitting the vent valve unit 32 therein.

通気弁ユニット３２の開閉機構としては、例えば、伸頂通気管２内が大気圧や正圧のときに、錘により弁体を閉止状態とし、伸頂通気管２内が負圧のときに、その負圧によって弁体を開放位置に揺動させる錘を利用した回転式の開閉機構を用いることができる。通気弁ユニット３２の上方側部位には、その周方向に間隔を隔てて複数の通気弁開口部３４が形成され、この通気弁開口部３４を通して、その周囲からの空気を通気弁ユニット３２の内部に取込自在に構成されている。なお、本実施形態に係る通気弁付き収納ボックスに適用可能な通気弁はこのような構造のものに限定されず、伸頂通気管又は排水管に連通接続可能であり、それらの管内が大気圧又は正圧時に閉じて負圧時に開く機能を有し、且つ、下記のように収納ボックスへの固定が可能なものであれば、特に制限なく適用することができる。 The opening/closing mechanism of the vent valve unit 32 is, for example, when the inside of the summit ventilation pipe 2 is at atmospheric pressure or positive pressure, the valve body is closed by a weight, and when the inside of the summit ventilation pipe 2 is under negative pressure, the valve body is closed. A rotary opening/closing mechanism using a weight that swings the valve body to the open position by the negative pressure can be used. A plurality of ventilation valve openings 34 are formed in the upper part of the ventilation valve unit 32 at intervals in the circumferential direction, and air from the surroundings is drawn into the inside of the ventilation valve unit 32 through these ventilation valve openings 34. It is structured so that it can be freely incorporated into. Note that the ventilation valve that can be applied to the storage box with ventilation valve according to this embodiment is not limited to one having such a structure, and can be connected to a top ventilation pipe or a drain pipe, so that the inside of these pipes is kept under atmospheric pressure. Alternatively, it can be applied without any particular limitation as long as it has the function of closing when positive pressure and opening when negative pressure is applied, and can be fixed to the storage box as described below.

As shown in FIGS. 1 and 2, the closing portion 5 has a rectangular plate shape that closes the open portion 45 of the storage box 4, and is configured to be freely attached to the storage box 4 with a fixture 7. As shown in FIGS. 1 to 3, the closed portion 5 has a first opening 101 that opens a part of the open portion 45. As shown in FIGS. FIG. 3 shows a perspective view of the closure portion 5 seen from the front side. The closing part 5 is configured to be larger than the storage box 4 by a predetermined amount in the vertical and horizontal directions, and as shown in FIGS. Only the corresponding area is opened, and all other areas are closed. As shown in FIGS. 2 to 4, the first opening 101 is a rectangular opening that is elongated in the left-right direction and is disposed in the closing part 5 at a position corresponding to the upper end side of the open part 45 of the storage box 4. is formed. FIG. 4 shows a front view of the storage box 4 with the closing part 5 and the cover part 6 attached, with the wall 204 and the like omitted.

閉塞部５には、図１及び図３に示すように、固定具７にて収納ボックス４に取り付けるための取付孔部１０２が形成されている。取付孔部１０２は、閉塞部５において、上下方向の中央部における左右両端部に配設されている。これにより、閉塞部５を収納ボックス４に取り付ける場合には、閉塞部５の取付孔部１０２と収納ボックス４の固定具用取付部６２とを位置合わせして、取付孔部１０２を挿通させた固定具７を固定具用取付部６２に取り付けることで、収納ボックス４に対して閉塞部５を所望位置に位置合わせした状態で、収納ボックス４に閉塞部５を取り付けることができる。閉塞部５の左上端部位には、図３に示すように、閉塞部５の上端部位であることを示す上端識別部１０４（「ｕｐ△」）が備えられ、作業者が、閉塞部５の上端部位がどの部位であるかを容易に認識できるようにしている。 As shown in FIGS. 1 and 3, the closing portion 5 is formed with a mounting hole 102 for attaching it to the storage box 4 with the fixture 7. The attachment holes 102 are disposed at both left and right ends of the vertically central portion of the closing portion 5 . As a result, when attaching the closure part 5 to the storage box 4, the attachment hole part 102 of the closure part 5 and the fixture attachment part 62 of the storage box 4 are aligned, and the attachment hole part 102 is inserted. By attaching the fixing device 7 to the fixing device attachment portion 62, the closing portion 5 can be attached to the storage box 4 while the closing portion 5 is aligned at a desired position with respect to the storage box 4. As shown in FIG. 3, the upper left end portion of the closing portion 5 is provided with an upper end identification portion 104 (“up△”) indicating that it is the upper end portion of the closing portion 5. This makes it easy to recognize which part is the upper end part.

カバー部６は、図１及び図２に示すように、収納ボックス４の外部からの空気を吸気自在な第２開口部１１１を有し、その第２開口部１１１と閉塞部５の第１開口部１０１とを連通させる状態で閉塞部５を覆うように備えられている。カバー部６は、上下方向及び左右方向で閉塞部５と略同じ大きさに構成されている。カバー部６は、図３に示すように、上端部位、両側端部位、及び、下端部位の夫々を後方側に折り曲げた折曲部１１２を有する折り曲げ板状に構成され、その後方側の内部に折曲部１１２にて周囲が囲まれた中空空間が形成されている。図３では、カバー部６について後方側から見た斜視図を示している。カバー部６は、折曲部１１２が閉塞部５の外周部に係合（嵌まり込む）する状態で閉塞部５に取付自在に構成されている。これにより、カバー部６の折曲部１１２の後端部を閉塞部５に当接させる状態でカバー部６を閉塞部５に取り付けることで、図２に示すように、閉塞部５とカバー部６との間に、第２開口部１１１と第１開口部１０１とを連通させる連通部１１３が形成されている。 As shown in FIGS. 1 and 2, the cover part 6 has a second opening 111 that can freely take in air from outside the storage box 4, and the second opening 111 and the first opening of the closing part 5 are connected to each other. It is provided so as to cover the closing part 5 in a state of communicating with the part 101. The cover portion 6 is configured to have approximately the same size as the closing portion 5 in the vertical and horizontal directions. As shown in FIG. 3, the cover portion 6 is formed into a bent plate shape having bent portions 112 in which the upper end portion, both side end portions, and the lower end portion are bent rearward. A hollow space surrounded by the bent portion 112 is formed. FIG. 3 shows a perspective view of the cover portion 6 viewed from the rear side. The cover portion 6 is configured to be freely attachable to the closure portion 5 in a state in which the bent portion 112 engages with (fits into) the outer peripheral portion of the closure portion 5 . As a result, by attaching the cover part 6 to the closing part 5 with the rear end of the bent part 112 of the cover part 6 in contact with the closing part 5, the closing part 5 and the cover part can be connected to each other as shown in FIG. A communication portion 113 is formed between the second opening 111 and the first opening 101 to communicate with each other.

連通部１１３は、図３及び図４に示すように、通路形成部１１４により、左右方向で収納ボックス４の一端側端部に延びたのち、その一端側端部にて反対側に折り返して収納ボックス４の他端側端部に延びる蛇行状の通路にて構成されている。ちなみに、この実施形態では、複数の蛇行状の通路が連続する状態で備えられているが、例えば、左右方向で往復するだけの１つの蛇行状の通路かを備えることもできる。図４では、連通部１１３の形状等を分かり易くするために、カバー部６及びカバー部６に備えられる各部を点線にて示している。通路形成部１１４は、図３に示すように、カバー部６の後面部から後方側に延びる起立壁状に形成されている。通路形成部１１４は、図３において、右側の折曲部１１２から左側の折曲部１１２の所定量だけ手前位置まで左右方向に延びる第１通路形成部１１４ａと、左側の折曲部１１２から右側の折曲部１１２の所定量だけ手前位置まで左右方向に延びる第２通路形成部１１４ｂとが、上下方向で交互に存在するように配設されている。 As shown in FIGS. 3 and 4, the communication portion 113 extends in the left-right direction to one end of the storage box 4 by the passage forming portion 114, and then is folded back to the opposite side at the one end for storage. It is constituted by a meandering passage extending to the other end of the box 4. Incidentally, in this embodiment, a plurality of meandering passages are provided in a continuous state, but for example, it is also possible to provide one meandering passage that only reciprocates in the left and right direction. In FIG. 4, the cover part 6 and each part included in the cover part 6 are shown by dotted lines in order to make it easier to understand the shape of the communication part 113, etc. As shown in FIG. 3, the passage forming portion 114 is formed in the shape of an upright wall extending rearward from the rear surface portion of the cover portion 6. As shown in FIG. In FIG. 3, the passage forming part 114 includes a first passage forming part 114a that extends in the left-right direction from the right bent part 112 to a position in front of the left bent part 112 by a predetermined distance, and a first passage forming part 114a that extends from the left bent part 112 to the right side. 2nd passage forming portions 114b extending in the left-right direction by a predetermined distance to a position in front of the bent portion 112 are arranged so as to alternate in the vertical direction.

第２開口部１１１は、図２及び図３に示すように、カバー部６において、収納ボックス４の下端側部位に相当する位置に配設されている。第２開口部１１１は、図３に示すように、下端部位の折曲部１１２を切り欠く（備えない）ことで、下方側に向けて開口されており、前方側からは第２開口部１１１が視認できない位置に備えられている。ちなみに、この実施形態では、閉塞部５及びカバー部６が、収納ボックス４の開放部４５よりも上下方向及び左右方向で所定量だけ大きく構成されていることから、第２開口部１１１が、収納ボックス４の下端側部位よりも所定量だけ下方側に配設されている。 As shown in FIGS. 2 and 3, the second opening 111 is disposed in the cover portion 6 at a position corresponding to the lower end portion of the storage box 4. As shown in FIGS. As shown in FIG. 3, the second opening 111 is opened downward by cutting out (not including) the bent part 112 at the lower end, and from the front side, the second opening 111 is installed in a location where it cannot be seen. Incidentally, in this embodiment, since the closing part 5 and the cover part 6 are configured to be larger by a predetermined amount in the vertical and horizontal directions than the open part 45 of the storage box 4, the second opening 111 is larger than the opening part 45 of the storage box 4. It is disposed a predetermined amount below the lower end portion of the box 4 .

カバー部６は、閉塞部５との係合により閉塞部５及び固定具７を覆う状態で閉塞部５に対して取付自在に構成されている。そのために、図３に示すように、閉塞部５には、取付用被係合部１０３が備えられ、カバー部６には、取付用被係合部１０３に係合する取付用係合部１１５が備えられている。取付用被係合部１０３は、矩形状の閉塞部５の角部（四隅部）の夫々に配設され、後方側に凹入させた凹入溝部にて構成されている。取付用係合部１１５は、矩形状のカバー部６の角部（四隅部）の夫々に配設され、後方側に突出する突起部にて構成されている。これにより、カバー部６における取付用係合部１１５を閉塞部５における取付用被係合部１０３に係合させることで、閉塞部５及び固定具７を覆う状態でカバー部６を閉塞部５に対して取付自在としている。 The cover part 6 is configured to be freely attachable to the closure part 5 in a state where it covers the closure part 5 and the fixture 7 by engaging with the closure part 5 . To this end, as shown in FIG. 3, the closing portion 5 is provided with an attachment engaged portion 103, and the cover portion 6 is provided with an attachment engagement portion 115 that engages with the attachment engagement portion 103. is provided. The attachment engagement portions 103 are disposed at each corner (four corners) of the rectangular closing portion 5, and are constituted by recessed grooves recessed toward the rear side. The attachment engagement portions 115 are provided at each of the corners (four corners) of the rectangular cover portion 6 and are constituted by protrusions that protrude rearward. As a result, by engaging the attachment engagement portion 115 of the cover portion 6 with the attachment engagement portion 103 of the closure portion 5, the cover portion 6 is moved to the closure portion 5 while covering the closure portion 5 and the fixture 7. It can be installed freely against.

閉塞部５に対してカバー部６を取り付ける場合に、カバー部６の姿勢が適正姿勢であると、閉塞部５に対するカバー部６の係合を許容し、且つ、カバー部６の姿勢が適正姿勢以外の姿勢であると、閉塞部５に対するカバー部６の係合を阻害する取付姿勢調整部１２１（図３参照）が備えられている。 When attaching the cover part 6 to the closing part 5, if the posture of the cover part 6 is in the proper posture, engagement of the cover part 6 with the closing part 5 is allowed, and the posture of the cover part 6 is in the proper posture. An attachment attitude adjustment part 121 (see FIG. 3) is provided that inhibits engagement of the cover part 6 with the closing part 5 if the cover part 6 is in any other attitude.

カバー部６は、図１に示すように、第２開口部１１１が下方側に位置する姿勢が適正姿勢に設定されている。取付姿勢調整部１２１は、図３及び図５に示すように、閉塞部５の外周部や取付用被係合部１０３等の閉塞部５側の被係合部と、カバー部６の折曲部１１２や取付用係合部１１５等のカバー部６側の係合部とを有し、カバー部６が適正姿勢であるか否かによって、カバー部６が閉塞部５に係合するか否かを切り替えている。そのために、取付用係合部１１５及び取付用被係合部１０３は、上下方向での中央部から配設位置までの距離を、上方側部位に配設されるものと下方側配設されるものとで異ならせている。 As shown in FIG. 1, the cover portion 6 is set to have a proper posture in which the second opening 111 is located on the lower side. As shown in FIGS. 3 and 5, the attachment attitude adjusting section 121 is configured to adjust the engaged parts on the closing part 5 side, such as the outer peripheral part of the closing part 5 and the engaging part 103 for attachment, and the bending of the cover part 6. The cover part 6 has an engaging part on the cover part 6 side such as a part 112 and an engaging part 115 for attachment, and whether or not the cover part 6 engages with the closing part 5 depends on whether the cover part 6 is in a proper posture. I am switching between Therefore, the engaging part 115 for attachment and the engaged part 103 for attachment are arranged in such a manner that the distance from the center part to the disposed position in the vertical direction is different from the one disposed at the upper side and the one disposed at the lower side. It's different depending on the thing.

例えば、図５に示すように、閉塞部５において、上下方向の中央部に相当する取付孔部１０２から上方側部位に配設された上側の取付用被係合部１０３ａまでの距離Ｋ１を、上下方向の中央部に相当する取付孔部１０２から下方側部位に配設された下側の取付用被係合部１０３ｂまでの距離Ｋ２よりも大きくして、距離Ｋ１と距離Ｋ２とを異ならせている。これにより、上側の取付用被係合部１０３ａから閉塞部５の外周部（上端部）までの距離と、下側の取付用被係合部１０３ｂから閉塞部５の外周部（下端部）までの距離とが異なっている。よって、カバー部６が適正姿勢である場合には、閉塞部５の外周部にカバー部６の折曲部１１２を係合させながら、取付用被係合部１０３に対する取付用係合部１１５の係合も行うことがで、閉塞部５に対してカバー部６を適切に係合させて取り付けることができる。それに対して、カバー部６が上下反転している等、適正姿勢以外の場合には、閉塞部５の外周部にカバー部６の折曲部１１２を係合させようとすると、取付用被係合部１０３に取付用係合部１１５を係合させることができず、逆に、取付用被係合部１０３に取付用係合部１１５を係合させようとすると、閉塞部５に対してカバー部６が外側にはみ出してしまい、閉塞部５の外周部にカバー部６の折曲部１１２を係合させることができない。 For example, as shown in FIG. 5, in the closing part 5, the distance K1 from the mounting hole 102 corresponding to the center part in the vertical direction to the upper mounting engaged part 103a disposed in the upper part is, The distance K1 and the distance K2 are made to be larger than the distance K2 from the mounting hole portion 102 corresponding to the center portion in the vertical direction to the lower mounting engaged portion 103b arranged at the lower side portion, and the distance K1 and the distance K2 are made different. ing. As a result, the distance from the upper engaged part 103a for attachment to the outer periphery (upper end) of the closing part 5, and the distance from the lower engaged part 103b for attachment to the outer periphery (lower end) of the closing part 5. The distance is different. Therefore, when the cover part 6 is in the proper posture, the bent part 112 of the cover part 6 is engaged with the outer circumferential part of the closing part 5 while the engaging part 115 for attachment is engaged with the engaged part 103 for attachment. By also performing the engagement, the cover part 6 can be appropriately engaged and attached to the closing part 5. On the other hand, if the cover part 6 is not in the proper posture, such as when it is upside down, when trying to engage the bent part 112 of the cover part 6 with the outer circumferential part of the closing part 5, If the engagement part 115 for attachment cannot be engaged with the mating part 103, and conversely, the engagement part 115 for attachment cannot be engaged with the engaged part 103 for attachment, The cover portion 6 protrudes outward, and the bent portion 112 of the cover portion 6 cannot be engaged with the outer peripheral portion of the closing portion 5.

このようにして、収納ボックス４（通気弁付き収納ボックス１）の前面部に、閉塞部５及びカバー部６が取り付けられると、図２に示すように、第２開口部１１１と第１開口部１０１とを連通部１１３にて連通させる状態で閉塞部５を覆うカバー部６が備えられている。これにより、収納ボックス４の外部からの空気は、カバー部６の第２開口部１１１から吸気されて連通部１１３にて第１開口部１０１に導かれ、その第１開口部１０１を通して収納ボックス４の内部空間４６に到達することになる。よって、通気弁３が開状態となった場合には、収納ボックス４の内部空間４６に到達する空気を伸頂通気管２を通して排水管内に取り込むことができる。 When the closing part 5 and the cover part 6 are attached to the front part of the storage box 4 (storage box 1 with ventilation valve) in this way, as shown in FIG. 101 is provided with a cover part 6 that covers the closing part 5 in a state of communicating with it through a communication part 113. As a result, air from outside the storage box 4 is sucked in through the second opening 111 of the cover part 6 and guided to the first opening 101 through the communication part 113, and passes through the first opening 101 to the storage box 4. It reaches the internal space 46 of. Therefore, when the ventilation valve 3 is in the open state, air reaching the internal space 46 of the storage box 4 can be taken into the drain pipe through the elongated top ventilation pipe 2.

第１開口部１０１にて収納ボックス４の開放部４５を開口させるものの、基本的には、閉塞部５が、収納ボックス４の開放部４５を閉塞しているので、通気弁３が開状態となった場合に、収納ボックス４の内部空間４６における排水音が、開放部４５を通して、そのまま収納ボックス４の外部側に伝達されるのを防止することができる。 Although the first opening 101 opens the opening 45 of the storage box 4, the closing portion 5 basically closes the opening 45 of the storage box 4, so the ventilation valve 3 is not in the open state. In this case, the drainage sound in the internal space 46 of the storage box 4 can be prevented from being directly transmitted to the outside of the storage box 4 through the opening 45.

しかも、収納ボックス４において、通気弁３が収納ボックス４の下端側部位に相当する位置に配設され、第１開口部１０１が、閉塞部５において、収納ボックス４の上端側部位に相当する位置に配設され、第２開口部１１１が、カバー部６において、収納ボックス４の下端側部位に相当する位置に配設されている。よって、通気弁３、第１開口部１０１、第２開口部１１１の配置関係については、上下方向において、通気弁３の配設位置と第１開口部１０１の配設位置との位置関係が収納ボックス４の中央部を基準に反対側となり、第１開口部１０１の配設位置と第２開口部１１１の配設位置との位置関係も収納ボックス４の中央部を基準に反対側となっている。これにより、通気弁３と第１開口部１０１との間の距離だけでなく、第１開口部１０１と第２開口部１１１との間の距離も長く取ることができるので、排水音が収納ボックス４の外部に伝達されるまでの過程で、排水音が分散したり、排水音が壁部等で反射されることになり、排水音の低減を効果的に図ることができる。 Moreover, in the storage box 4, the ventilation valve 3 is arranged at a position corresponding to the lower end side of the storage box 4, and the first opening 101 is arranged in the closing part 5 at a position corresponding to the upper end side of the storage box 4. The second opening 111 is disposed in the cover portion 6 at a position corresponding to the lower end portion of the storage box 4 . Therefore, regarding the arrangement relationship between the ventilation valve 3, the first opening 101, and the second opening 111, the positional relationship between the arrangement position of the ventilation valve 3 and the arrangement position of the first opening 101 in the vertical direction is The positions are opposite to each other with respect to the center of the box 4, and the positional relationship between the first opening 101 and the second opening 111 is also opposite with respect to the center of the storage box 4. There is. As a result, not only the distance between the ventilation valve 3 and the first opening 101 but also the distance between the first opening 101 and the second opening 111 can be made longer, so that the sound of drainage can be reduced from the storage box. In the process of being transmitted to the outside of 4, the drainage sound is dispersed and reflected by the walls, etc., so that the drainage sound can be effectively reduced.

上述の閉塞部５及びカバー部６を取り付けた場合に、カバー部６の前方側等の収納ボックス４外において、排水音をどれだけ低減できているかの実験を行った。その実験結果を表１に示している。表１では、通気弁３が閉弁状態であり、排水音が収納ボックス４内に伝達されていない状態での音の大きさを測定した場合を環境音としている。例えば、閉塞部５及びカバー部６を取り外して、通気弁３が開弁状態となり、排水音をそのまま測定した場合を排水音としている。上述の閉塞部５及びカバー部６を取り付けた状態で排水音を測定した場合を本実施形態としている。 An experiment was conducted to see how much drainage sound could be reduced outside the storage box 4, such as on the front side of the cover part 6, when the above-mentioned closing part 5 and cover part 6 were attached. The experimental results are shown in Table 1. In Table 1, the environmental sound is defined as the sound level measured when the ventilation valve 3 is in the closed state and the drainage sound is not transmitted into the storage box 4. For example, when the blocking part 5 and the cover part 6 are removed, the vent valve 3 is in an open state, and the drainage sound is directly measured, the drainage sound is defined as the drainage sound. In this embodiment, the drainage sound is measured with the above-mentioned closing part 5 and cover part 6 attached.
